Description

Technical Field

[0001] The present invention relates to the technical field of welding interconnection bar processing, and in particular to a welding interconnection bar processing method and device. Background Art

[0002] Solar cell welding is the process of welding solar cells and interconnecting bars together at high temperature. The cells are connected in series or in parallel through the interconnecting bars to form a battery module. During welding, the cells are arranged at set intervals, and the interconnecting bars cross across the surface of the cells to achieve series connection of the cells.

[0003] In the prior art, in order to prevent the edges of front and rear adjacent battery cells or the ends of front and rear adjacent welding interconnection strips from contacting each other and causing a short circuit, a gap of 0.5 to 2 mm is left between adjacent battery cells, and the two ends of each welding interconnection strip are indented 2 to 5 mm from the edge of the battery cell, which requires that a distance of about 10 mm be maintained between the ends of two adjacent welding interconnection strips. In order to obtain a group of interconnection strips distributed along the length and with a head-to-tail spacing of 10 mm at one time, the current practice is to pull a long welding interconnection strip and lay it on a stamping die, and a number of evenly spaced cutters will cut the welding interconnection strip into a number of evenly spaced short welding interconnection strips at one time. The welding interconnection strips at a gap of about 10 mm between the welding interconnection strips will be cut off when they are truncated, that is, a long interconnection strip is cut off by 10 mm at a certain distance to obtain a group of short interconnection strips with a head-to-tail spacing of 10 mm.

[0004] However, each short interconnection strip is about 170 cm long. If 10 cm is cut off every 170 cm, the loss is about 5.5-6%, which is a relatively large loss. At the same time, the existing welding interconnection strip processing solution adopts an overall design method, and due to process requirements, the interconnection strip processing device needs to be frequently disassembled, maintained or replaced. When a part of it fails and needs maintenance or replacement, the part needs to be disassembled as a whole for maintenance or replacement, which not only requires a lot of work but also causes a huge waste of cost. In addition, the existing welding interconnection strip cutting and pressing structure adopts a cylinder plus connecting rod structure. When cutting and pressing, the cutter and the pressing block have a rotating downward pressing action. In the actual production process, this rotating action will cause the welding interconnection strip to rub and produce torsional deformation around the central axis. Whether rubbing or deformation, the interconnection strip cannot be accurately placed in the predetermined welding position, resulting in poor welding. Summary of the invention

[0005] The purpose of the present invention is to provide a method and device for processing welding interconnection strips, aiming to solve the problem that each short interconnection strip is about 170 cm long, and the loss is about 5.5-6% calculated by cutting 10 cm every 170 cm, which is a relatively large loss; at the same time, the existing welding interconnection strip processing scheme adopts an overall design method, and because of process requirements, the interconnection strip processing device needs to be frequently disassembled, maintained or replaced. When a part of it fails and needs maintenance or replacement, the part needs to be disassembled as a whole for maintenance or replacement, which not only requires a large workload but also causes a huge waste of cost; and the existing welding interconnection strip cutting and pressing structure adopts a cylinder plus connecting rod structure. When cutting and pressing, the cutter and the pressing block have a rotating downward pressing action.

The welding interconnection strip is cut off by the device, thereby avoiding the problem of material waste caused by the cutting of the welding interconnection strip, and saving 5% of the cost of the welding interconnection strip. In this way, the problem is effectively solved that each short interconnection strip is about 170 cm long, and according to the calculation of cutting 10 cm every 170 cm, the loss is about 5.5-6%, which is a large loss.

In addition, the existing welding interconnection bar cutting and pressing structure adopts a cylinder plus connecting rod structure. When cutting and pressing, the cutter and the pressing block have a rotating downward pressing action. In the actual production process, this rotating action will cause the welding interconnection bar to rub and produce torsional deformation around the central axis. Whether rubbing or deformation, the interconnection bar cannot be accurately placed in the predetermined welding position, resulting in technical problems such as poor welding.

[0037] Furthermore, the first frame 1, the two auxiliary frames 2 and the third frame 3 are all provided with transverse guide rails 5, slot plates 6 and translation cylinders 7, two transverse sliders 8 are slidably provided on the transverse guide rails 5, and moving seats 9 are provided on the two transverse sliders 8, and a fixed plate 10 is provided on the moving seat 9, and a pressure claw mechanism is provided on the end surface of the fixed plate 10, and the fixed plate 10 is driven by the translation cylinder 7, and a limit plate 11 and a plurality of guide grooves 12 are provided on the slot plate 6, and a plurality of limit grooves 13 are provided on the limit plate 11, and the other end surfaces of the fixed plates 10 of the first frame 1 and the two auxiliary frames 2 are all provided with a lower cutter lifting cylinder 16 and a plurality of upper cutter bodies 17, and a lower cutter sliding plate 18 is provided at the output end of the lower cutter lifting cylinder 16, and a plurality of lower cutter bodies 19 are provided on the lower cutter sliding plate 18.

[0038] Furthermore, the transverse guide rail 5 is located at the inner bottom of the first frame 1, the two auxiliary frames 2 and the third frame 3, the groove plate 6 is located above the first frame 1, the two auxiliary frames 2 and the third frame 3, and the translation motor 31 is located on the inner side of the first frame 1, the two auxiliary frames 2 and the third frame 3.

[0039] Furthermore, the other end surface of the fixed plate 10 of the first frame 1 and the two auxiliary frames 2 is also provided with two lower cutter lifting guide rails 20, and lower cutter lifting sliders 21 are provided at both ends of the sliding plate, and the lower cutter lifting sliders 21 are sleeved on the lower cutter lifting slide rails.

[0040] Furthermore, the pressing claw mechanism includes a pressing claw sliding plate 22, two pressing claw lifting guide rails 23 and a pressing claw lifting cylinder 24, a plurality of pressing claw bodies 25 are arranged on the pressing claw sliding plate 22, and two pressing claw lifting sliders 26 are arranged on the end face of the pressing claw sliding plate 22, the pressing claw sliding plate 22 is fixedly connected to the pressing claw lifting cylinder 24 and is located at the output end of the pressing claw lifting cylinder 24, the two pressing claw lifting guide rails 23 are respectively fixedly connected to the fixed plate 10 and are located on the end face of the fixed plate 10, the pressing claw lifting cylinder 24 is fixedly connected to the fixed plate 10 and is located on the end face of the fixed plate 10, and the two pressing claw lifting sliders 26 are respectively sleeved on the corresponding pressing claw lifting guide rails 23.

[0041] In this embodiment, by starting the pressure claw lifting cylinder 24, the pressure claw lifting cylinder 24 pushes the pressure claw sliding plate 22 upward, and the multiple pressure claw bodies 25 move in the direction away from the guide groove 12, which is convenient for the entry of the welding interconnection strip. Then, the pressure claw lifting cylinder 24 moves the pressure claw sliding plate 22 downward, so that the multiple pressure claw bodies 25 move downward and press the welding interconnection strip, so as to achieve the clamping and release of the welding interconnection strip, ensuring that the welding interconnection strip will not shift during the cutting process, thereby improving the accuracy and stability of the cutting.

[0042] Further, the plurality of upper cutter bodies 17 and the plurality of pressing claw bodies 25 are all higher than the corresponding guide grooves 12 , and the plurality of lower cutter bodies 19 are all lower than the corresponding guide grooves 12 .

[0043] In this embodiment, this structure can ensure that the cutting and pressing operations can act on the welding interconnection strip at the same time, thereby improving the cutting efficiency and accuracy.

[0044] Furthermore, the spacing drive mechanism includes two spacing guide rails 27, a rack plate 28 and a base plate 29, the two spacing guide rails 27 are respectively fixedly connected to the base plate 29 and are located above the base plate 29, and a plurality of the second frames and the third frames 3 are respectively slidably arranged on the corresponding spacing guide rails 27 through the longitudinal slider 15, the rack plate 28 is fixedly connected to the base plate 29 and is located on one side of the base plate 29, and the drive mechanism is arranged on the rack plate 28.

[0045] Furthermore, the driving mechanism includes a gear 30, a motor 31 and a bracket 32, the gear 30 is fixedly connected to the motor 31 and is located at the output end of the motor 31, and the gear 30 is meshed with the rack plate 28 and is located on the rack plate 28, the motor 31 is fixedly connected to the bracket 32 ​​and is located below the bracket 32, and the gear 30 extends into the bracket 32, and the bracket 32 ​​is fixedly connected to the connecting plate 14 and is located below the connecting plate 14.

[0046] In this embodiment, by starting the motor 31, the motor 31 drives the gear 30 to rotate, and the connecting plate 14 moves under the action of the rack plate 28 and the gear 30, thereby realizing spacing adjustment, and then the spacing between the welding interconnected strips can be accurately adjusted to meet different truncation requirements.

[0047] Furthermore, the pressing and cutting actions of the pressing claw body 25 and the lower cutter body 19 are in a vertical state, and are perpendicular to the direction of the slot plate 6 and perform linear motion.

[0048] In the invention, the welding interconnection strip is first laid in the corresponding guide groove 12, and the multiple upper cutter bodies 17 and the multiple lower cutter bodies 19 are moved toward the position of the guide groove 12 under the action of the translation cylinder 7 and cover the guide groove 12. At this time, the upper cutter body 17, the lower cutter body 19 and the guide groove 12 restrict the welding interconnection strip from four directions of up, down, left and right. Then, the lower cutter lifting cylinder 16 pushes the lower cutter body 19 upward to move and cut off the welding interconnection strip. After the welding interconnection strip is cut off, the lower cutter body 19 descends, and then the upper cutter body 17 and the lower cutter body 19 move to the left. The above operation process is repeated to continuously cut off the welding interconnection strip.

[0049] In the invention, firstly, the pressure claw body 25 presses and fixes the welding interconnection strip to prevent the welding interconnection strip from deviating during cutting. Secondly, after cutting, the welding interconnection strip is spaced apart. The first frame 1, multiple second frames and the third frame 3 move to both sides with the welding interconnection strip. The pressure claw body 25 fixes the welding interconnection strip to prevent the welding interconnection strip from slipping and causing uneven spacing. The fixed plate 10 is slidably connected to the frame through the transverse slider 8 and the transverse guide rail 5, and the frame can push the fixed plate 10 to reciprocate in the horizontal direction in the translation cylinder 7, thereby driving the pressure claw body 25, multiple upper cutter bodies 17 and the lower cutter body 19 to reciprocate in the horizontal direction to make room for laying the welding interconnection strip. The pressure claw body 25 is slidably connected to the pressure claw lifting guide rail 23 and the fixed plate 10 through the pressure claw lifting slider 26, and the pressure claw body 25 reciprocates up and down under the action of the pressure claw lifting cylinder 24 to press the welding interconnection strip.

[0050] The present invention also provides a method for processing a welding interconnection bar, which is applied to the above-mentioned welding interconnection bar processing device and comprises the following steps:

[0051] S1: Laying the welding interconnection strip in the corresponding guide groove 12, and the plurality of upper cutter bodies 17, the plurality of lower cutter bodies 19 and the plurality of pressing claw bodies 25 are translated toward the direction of the guide groove 12 under the action of the translation cylinder 7, and cover the corresponding welding interconnection strip;

[0052] S2: Control the plurality of pressing claw bodies 25 to press down the welding interconnection strip, and then push the lower cutter body 19 upward based on the lower cutter lifting cylinder 16 to move, so as to cut off the welding interconnection strip;

[0053] S3: After the welding interconnection strip is cut off, the lower cutter body 19 descends, and the states of the plurality of pressing claw bodies 25 remain unchanged;

[0054] S4: Based on the driving mechanism, the first frame 1, the second frames and the third frame 3 are respectively moved to the specified spacing, and then the plurality of pressure claw bodies 25 are raised, and then the plurality of pressure claw bodies 25 and the plurality of upper cutter bodies 17 are controlled to translate and reset to make room for the next laying.

[0055] In the present invention, the design scheme makes the parts with the same functions and structures into separate modules, and the modules are assembled together to realize the maintenance or replacement of the separate modules. The production and processing of the modules are also simpler, and the modular design can reduce a lot of workload and maintenance costs; at the same time, the design of the linear motion truncation and compression method constrains and truncates the interconnection strip in one direction to ensure the shape of the interconnection strip is intact to improve the welding yield. In this way, the problem that each short interconnection strip is about 170 cm long and 10 cm is cut off every 170 cm is effectively solved. The loss is about 5.5-6%, which is relatively large; at the same time, the existing welding interconnection strip processing scheme adopts an overall design method, and Due to process requirements, the interconnection bar processing device needs to be frequently disassembled and maintained or replaced. When a part of it fails and needs maintenance or replacement, the entire part needs to be disassembled for maintenance or replacement, which not only requires a large workload but also causes a huge waste of cost. In addition, the existing welding interconnection bar cutting and pressing structure adopts a cylinder plus connecting rod structure. When cutting and pressing, the cutter and the pressing block have a rotating downward pressing action. In the actual production process, this rotating action will cause the welding interconnection bar to rub and produce torsional deformation around the central axis. Whether rubbing or deformation, the interconnection bar cannot be accurately placed in the predetermined welding position, resulting in technical problems such as poor welding.

[0056] In the present invention, the pressure claw body 25 and the lower cutter body 19 on the first frame 1 press and cut an odd number of welding interconnection bars; the pressure claw body 25 and the lower cutter body 19 on the second frame press and cut an even number of welding interconnection bars; the pressure claw body 25 and the lower cutter body 19 on one of the auxiliary frames 2 of the second frame press and cut an even number of welding interconnection bars, and the pressure claw body 25 and the lower cutter body 19 on the other auxiliary frame 2 press and cut an odd number of welding interconnection bars; the pressure claw body 25 on the third frame 3 presses an odd and even number of welding interconnection bars. This design adopts a modular design instead of making the two auxiliary frames 2 on the second frame into a whole, in order to reduce the maintenance and replacement workload and processing costs. At the same time, the cutting action adopted in this design is vertical lifting without rotation to ensure that the welding interconnection bars are not rubbed and twisted during pressing and cutting, thereby greatly improving the welding yield.

[0057] What is disclosed above is only a preferred embodiment of the present invention, and it certainly cannot be used to limit the scope of rights of the present invention.
