I. Background and Industry Demand for Dual-Y Vacuum Soldering Machine

In the fields of new energy, automotive electronics, industrial control power supply, and precision electrical components manufacturing, vacuum encapsulation is a core process for ensuring insulation, moisture-proofing, shock resistance, and corrosion resistance of products. Although traditional single-station vacuum encapsulation machines can complete non-bubble encapsulation operations, they can only handle a single batch of workpieces at a time. The loading and unloading, as well as the picking up and placing of products, require equipment to stop and wait. There are gaps in process connection, and overall production capacity is limited, making it difficult to meet the requirements of large-scale mass production. Ordinary atmospheric pressure encapsulation equipment also has quality issues such as bubble residue and non-compact encapsulation, and cannot meet the process standards of high-end precision products. The dual-Y vacuum encapsulation machine combines the advantages of dual-station cyclic operation structure and vacuum degassing technology, taking into account both precise encapsulation quality and efficient mass production capabilities, solving the industry problem of being unable to balance efficiency and quality of traditional equipment. It has become the mainstream equipment for the current upgrade of precision encapsulation automation. 

II. Structure and Operation Principle of Dual-Y Axis Dual-Station Equipment

The dual-Y vacuum encapsulation machine adopts an innovative dual-Y-axis independent movement and dual-station alternating operation structure, different from traditional single-platform encapsulation equipment. The entire machine is equipped with two sets of independent Y-axis worktables, with the workstations not interfering with each other and operating alternately in a cycle. The equipment integrates a vacuum negative pressure system, a dual-component precise proportioning system, a dynamic mixing mechanism, and an intelligent control system. The frame structure is stable, the operation has little jitter, and the long-term operation stability is excellent. The operation logic of the equipment is flexible. When one workstation enters the vacuum encapsulation and degassing solidification process, the staff can complete the operation of taking the finished product, placing the workpiece, and resetting the tooling in the other workstation. There is no need for equipment to stop, completely eliminating the waiting time for loading and unloading, and achieving uninterrupted continuous encapsulation operations. At the same time, the sealed vacuum chamber is suitable for dual-station rotation operation, maintaining a stable negative pressure environment continuously, and ensuring the consistency of encapsulation process for each batch of products.

III. Vacuum Degassing Technology, Ensuring Precise Encapsulation Quality

Bubbles, pores, and voids are the main quality hazards in the encapsulation of precision components, which will directly affect the insulation performance and service life of the products. The dual-Y vacuum encapsulation machine continues to use the mature negative pressure vacuum process, completing the entire process of vacuuming, degassing of the glue, and workpiece filling in the sealed chamber. The equipment can precisely control the vacuum degree of the chamber, effectively removing tiny bubbles mixed during the mixing and blending of the glue, and extracting the trapped air in the workpiece chamber, fine gaps, and the gaps between the pins of the components. Under the action of negative pressure, the fluidity and permeability of the glue are significantly improved, which can fully fill the irregular cavities, fine gaps, etc., and after curing, the glue body is dense, without pores, bubbles, or missing glue defects. The stable vacuum process can effectively avoid problems such as poor insulation, sealing failure, and glue cracking, and is suitable for encapsulation standards of high-demand products such as new energy modules, precision sensors, and automotive electronics.

IV. Precise Proportioned Supply of Glue, Adapting to Multiple Process Requirements

This equipment is equipped with an independent dual-channel precise metering supply system for A and B glues. The glues are stored separately and transported independently. It can freely adjust the proportion ratio according to different product process requirements, adapting to the production needs of multiple specifications of two-component glues. The precise pump body metering structure dispenses glue evenly and stably, effectively avoiding problems such as incomplete curing, softening of the glue, and color change and cracking caused by imbalance in the glue ratio. The equipment is compatible with various industrial encapsulation glues such as epoxy resin, polyurethane, and organic silicon, and can meet various process scenarios such as insulation sealing, heat conduction filling, and shock reinforcement. The storage tank can be selected with heating and uniform stirring functions as needed to effectively improve the problems of sedimentation, caking, and poor fluidity of high-viscosity glue, ensuring the stability of glue performance, and adapting to continuous encapsulation operations of various viscosities.

V. Flexible Dual-Station Production, Improving Mass Production Efficiency The dual-Y dual-station structure is the core highlight of this equipment. Compared with the traditional single-station vacuum injection molding machine, the production mode is more flexible and efficient. The two workstations operate independently and do not interfere with each other. They complete the operation in a cyclic manner, significantly improving the equipment utilization rate and effectively enhancing the overall production capacity. The equipment is equipped with an intelligent touch control operating system, which supports the storage of multiple sets of process parameters and one-click retrieval. It can preset parameters such as vacuum degree, vacuuming duration, injection speed, and output volume in advance. When changing product models, there is no need for repeated debugging, and the production transfer operation can be completed quickly. It is suitable for alternating production modes of multiple categories, small batches, and large batches. The entire equipment realizes fully automated operation for vacuuming, mixing, blending, injection, and resetting. Only the operators need to be responsible for loading and unloading, significantly reducing manual intervention, reducing operational errors, and improving the degree of production standardization.

Six. Equipment Maintenance Convenience and Environmental Benefits

The dual-Y vacuum injection molding machine adopts a modular integrated design, with a regular structure layout, strong core components, and a low overall failure rate. It can be adapted to long-term continuous production conditions in the workshop. The equipment is equipped with an automatic cleaning function. After the operation, it can quickly clean the residual glue in the pipelines to avoid glue drying and blocking the pipelines, and extend the service life of the accessories. The easily damaged parts of the dual-station are convenient to disassemble and assemble. Daily maintenance only requires cleaning the cavity, checking the pipeline sealingity, and maintaining the transmission structure to complete the basic maintenance. The maintenance cost is low, and the time is short. At the same time, the equipment adopts a closed negative pressure operation design, effectively reducing the diffusion of volatile gases from the glue, optimizing the workshop operation environment, and conforming to industrial environmental protection production norms. The precise glue control system can reduce glue overflow and residue waste, improve glue utilization rate, and help enterprises optimize production costs in the long term.
