Description

Technical Field

[0001] This invention belongs to the field of photovoltaic module printing equipment, and particularly relates to a printing equipment and method for multi-cell batteries. Background Technology

[0002] In the photovoltaic cell manufacturing field, screen printing technology is commonly used for the metallization process of crystalline silicon solar cells. This process has a crucial impact on the final electrical performance of the cells and the production line efficiency. Optimizing existing printing processes has become an important research direction in the industry, aiming to continuously reduce manufacturing costs and improve output efficiency.

[0003] Currently, most mainstream production lines adopt a single-cell serial printing mode, meaning that each printing operation is completed for only one battery cell. While this mode is technologically mature, as production line speed requirements increase, the original process, which produces only one battery cell per operation, is increasingly showing its limitations in efficiency, gradually becoming a major bottleneck restricting further breakthroughs in overall production capacity. To improve printing capacity per unit time, existing technologies mainly employ the following two improvement approaches: First, by arranging multiple independent printing machines in parallel to achieve capacity aggregation, but this method significantly increases equipment investment and factory space requirements, leading to a substantial increase in overall costs; Second, by integrating multiple independent printing units within a single machine, however, this solution makes the mechanical structure and control system exceptionally complex, not only increasing the difficulty of equipment manufacturing and maintenance but also facing problems such as difficulties in synchronization and coordination between units and reduced reliability in actual operation. Summary of the Invention

[0004] The present invention aims to solve the above-mentioned problems and provides a printing apparatus and method for printing multi-segment batteries that can simultaneously transmit and print multiple batteries.

[0005] In a first aspect, the present invention provides a method for printing multi-segmented batteries, the method comprising: S1. The battery pack to be printed is fed into the positioning component via the feeding and conveying component; S2, the CCD detection device detects each cell in the battery pack; based on the detection results, the battery handling and positioning components adjust the position of the cells. S3. The battery transport component transports the battery pack, after its position has been adjusted, to the printing platform; S4. The printing platform moves the battery pack to the printing position of the printing component; the printing component prints on the battery pack; the printing platform, including the A-track printing platform and the B-track printing platform, reciprocates between the battery pick / place position and the printing position of the two conveying devices. S5. The printing platform moves the printed battery pack to the battery pick / place position and transfers the battery pack to the discharge conveyor to complete the printing of a set of battery cells.

[0006] Furthermore, in the multi-segment battery printing method of the present invention, the positioning component includes a conveyor belt, a positioning platform, and an adjustment assembly arranged from top to bottom; the adjustment assembly includes a Y1 moving component, a Y2 moving component, an θ1 movable joint, an θ2 movable joint, and an X movable joint; the upper ends of the θ1 and θ2 movable joints are both connected to the positioning platform; the lower ends of the θ1 and θ2 movable joints are respectively connected to the Y1 and Y2 moving components; the X movable joint is disposed between the lower end of the θ2 movable joint and the Y2 moving component. Step S2, based on the detection results, involves the battery transport component and positioning component adjusting the position of the battery cells, including: S21. By adjusting the Y1 moving component, Y2 moving component, θ1 movable joint, θ2 movable joint, and X movable joint below the positioning component, the battery cell is moved in the Y direction and its angle deflection is adjusted; specifically including: S211. Move the Y1 moving part and the Y2 moving part synchronously and by the same distance to achieve the Y-axis adjustment of the positioning platform; S212. Move the Y1 moving part and the Y2 moving part synchronously, and the moving distances of the two moving parts are not the same. When the moving distances are not the same, the distance difference between the two causes the θ1 moving joint and the θ2 moving joint to start rotating. At the same time, the X moving joint provides the X-direction movement channel for rotation, thereby synchronously realizing the Y-direction adjustment and angle deflection adjustment of the positioning platform. S22. The battery transport component picks up the tested battery cell and moves it in the X direction. The X-direction movement of the battery cell is adjusted to complete the position adjustment of the battery cell.

[0007] Furthermore, in the multi-segment battery printing method of the present invention, step S4, in which the A-track printing platform and the B-track printing platform reciprocate between the battery pick-up / placement position and the printing position of the two conveying devices, includes: S41, the A-track printing platform moves to the battery pick / place position of the A-track conveyor to complete the transfer of the printed battery packs and the loading of the unprinted battery packs on the A-track. The B-track printing platform moves synchronously to the printing position to complete the printing of the unprinted battery packs on the B-track. S42, the A-track printing platform moves to the printing position to complete the printing of the unprinted battery packs on the A-track. The B-track printing platform moves synchronously to the pick-up / place-on battery position of the B-track conveyor to complete the transfer of the printed battery packs on the B-track and the transfer of the unprinted battery packs on the B-track. S43. Repeat steps S41-S42, and complete the continuous printing of multiple battery packs by coupling the A-track printing platform and the B-track printing platform in the Y direction.

[0008] Secondly, the present invention provides a printing apparatus for multi-segment batteries, comprising two parallel conveying devices, namely an A-track conveying device and a B-track conveying device. The conveying device includes a feeding conveying component, a positioning component, a battery pick-up / placement position, and a discharging conveying component arranged in sequence; a battery handling component is provided on one side of the positioning component and the battery pick-up / placement position; a CCD detection device is provided above the positioning component; The battery pick / place positions in the A-rail conveyor and the B-rail conveyor are coaxially arranged. A printed position is provided in the middle of the battery pick / place position in the A-rail conveyor and the B-rail conveyor. The printing station is equipped with printing components and a movable printing platform; The printing platform includes an A-track printing platform and a B-track printing platform; the A-track printing platform and the B-track printing platform are coupled.

[0009] Furthermore, in the multi-segment battery printing apparatus of the present invention, the positioning component includes a conveyor belt, a positioning platform, and an adjustment assembly arranged from top to bottom; The adjustment assembly includes a Y1 motion component, a Y2 motion component, an θ1 movable joint, an θ2 movable joint, and an X movable joint; the upper ends of the θ1 and θ2 movable joints are both connected to the positioning platform; the lower end of the θ1 movable joint is connected to the Y1 motion component; the X movable joint is located between the lower end of the θ2 movable joint and the Y2 motion component; the lower end of the X movable joint is connected to the Y2 motion component, and the upper end of the X movable joint is connected to the θ2 movable joint.

[0010] The technical solution of this application can produce the following beneficial effects:

[0011] 1. Effectively improve unit output and equipment utilization: Through the collaborative design of coupled dual printing platforms, the two platforms can operate in parallel. While one platform is performing the printing process, the other platform can simultaneously perform cell loading, unloading, and positioning preparation, thereby eliminating the station waiting time inherent in the traditional serial mode and achieving seamless connection of major process steps. This working mode minimizes equipment downtime and significantly improves the unit time output and overall operating efficiency of a single machine.

[0012] 2. Significantly Reduced Manufacturing and Operating Costs per Unit Capacity: Compared to traditional sequential printing of single cells, this solution can process multiple cells in a single transfer and printing operation. While achieving the same production line capacity, this design reduces the need for a larger number of printing units or parallel equipment, directly reducing the complexity and manufacturing cost of individual devices and saving space. Simultaneously, the optimized frequency of mechanism movements helps reduce long-term energy consumption and maintenance requirements, thereby lowering the unit manufacturing cost of battery production from both investment and operating cost perspectives.
