Description

Technical Field

[0001] This utility model relates to the field of photovoltaic equipment manufacturing, specifically to a filamentous material carrying device. Background Technology

[0002] During the string welding process, the welding ribbon needs to contact the grid lines on the battery cells and be aligned with them. Typically, the welding ribbon placed on the grid lines of the battery cells needs to be pulled from the ribbon tray by the ribbon traction device of the string welding machine and transported to a designated position via a ribbon lifting mechanism. Existing ribbon lifting mechanisms in string welding machines have solved the problem of the welding ribbon being difficult to fall into the lifting mechanism; for example, Chinese Utility Model Patent Publication No.: CN 220543937 U, entitled "A Ribbon Lifting Mechanism." However, this utility model has drawbacks. Because the string welding machine operates at high speed and continuously, and the welding ribbon itself is lightweight, even if the ribbon falls into the lifting mechanism, the high-speed movement of the mechanism or device within the string welding machine may cause the ribbon to deviate from the ribbon lifting mechanism, affecting the welding quality of subsequent battery strings. Utility Model Content

[0003] In view of the problems in the prior art, the purpose of the present invention is to provide a filamentous material carrying device.

[0004] This utility model provides the following technical solution: a filamentous material carrying device, including: a carrying plate, a limiting groove, and a sealing plate for closing the limiting groove; at least two guide grooves are opened on the upper surface of the carrying plate corresponding to the grid lines of the battery cell, the guide grooves extend outward to the limiting groove, and the sealing plate forms a sealing plate corresponding to the position of the limiting groove.

[0005] The design of the support plate, limiting groove, and sealing plate ensures that even when the equipment is operating at high speed continuously, the welding strip will not deviate from the guide groove due to high-speed movement, thus guaranteeing the quality of subsequent battery string welding.

[0006] Specifically, the inner wall of the guide groove and the top of the inner wall form a chamfer.

[0007] Preferably, the width of one end of the guide groove is greater than the width of the other end, and the depth of one end of the guide groove is greater than the depth of the other end.

[0008] With the guide groove, even if the pulled-out welding strip has a positional deviation, it can slide into the guide groove through the chamfer at the top of the guide groove. Even if the tail of the welding strip shakes after being cut, it will not fall out of the guide groove. Furthermore, the slightly deformed welding strip can be reshaped when it is pulled out of the guide groove.

[0009] As a further aspect of the present invention, it also includes a telescopic power device, which is connected to the sealing plate. The telescopic power device can drive the sealing plate to move laterally relative to the bearing plate, thereby realizing the lateral movement of the sealing plate relative to the limiting groove and realizing the opening and closing of the limiting groove.

[0010] As a further embodiment of the present invention, it also includes a lifting power device and a translating power device. The lifting power device is connected to the bearing plate, and the translating power device is connected to the lifting power device. By setting up the lifting power device and the translating power device, the filament material bearing device can avoid interference with other devices of the equipment and perform translation in the direction of the battery cell grid line, thereby realizing the full-process limited bearing of the welding strip.

[0011] In summary, the design of the support plate, limiting groove, and sealing plate ensures that even under high-speed continuous operation, the welding strip will not deviate from the guide groove due to high-speed movement, thus guaranteeing the quality of subsequent battery string welding. The guide groove allows the pulled-out welding strip to slide back into the groove even with positional deviations, thanks to the chamfer at the top. Even if the tail of the welding strip wobbles after being cut, it will not detach from the guide groove, and slight deformation of the welding strip can be reshaped when it is pulled out. The telescopic power device allows the sealing plate to move laterally relative to the support plate, thereby enabling the sealing plate to move laterally relative to the limiting groove, facilitating the opening and closing of the limiting groove. The lifting and translational power devices prevent interference between the filamentous material carrying device and other equipment components, and allow for translational movement along the battery cell grid lines, achieving full-process limiting and carrying of the welding strip.

Detailed Implementation

[0019] This application relates to a device for carrying filamentous materials, which will be explained in detail below through specific embodiments.

[0020] In view of the problems existing in the prior art, in order to avoid the welding strip deviating from the welding strip support groove of the welding strip support mechanism due to the high speed of the equipment, this application provides a filamentous material support device for supporting, guiding and limiting the welding strip pulled out by the welding strip traction device. The filamentous material support device includes a support plate 10, a limiting groove 12 and a sealing plate 20 for closing the limiting groove 12.

[0021] During the movement of the welding ribbon to the cell grid lines, it needs to be supported and assisted in transportation. Therefore, the filamentous material carrying device includes a support plate 10 for supporting and assisting in the transportation of the welding ribbon. However, during the welding process of the battery string, since the welding ribbon needs to contact the grid lines on the cell and be on the same straight line, the contact accuracy requirement is high. Therefore, the upper surface of the support plate 10 is provided with 20 guide grooves 11 parallel to the cell grid lines and arranged at equal intervals along the long side of the support plate 10. The support plate 10 not only supports and assists in the transportation of the welding ribbon during its movement, but also guides it, ensuring the contact accuracy between the welding ribbon and the cell grid lines.

[0022] Because the contact precision requirements between the solder ribbon and the cell grid lines are high, the width of the guide groove 11 will also be narrowed due to the precision requirements. This makes it difficult for the solder ribbon to fall into the guide groove 11 due to positional deviation. Therefore, the inner wall and the top of the inner wall of the guide groove 11 are chamfered 13. Through the chamfer 13 formed at the top of the guide groove 11, even if there is a positional deviation, the solder ribbon can slide into the guide groove 11 through the chamfer 13 at the top of the guide groove 11.

[0023] When the welding strip enters the guide groove 11, the tail of the welding strip will shake and slightly deform due to the pulling force of the welding strip traction device (not shown in the figure) when it is cut to a fixed length. In order to prevent the welding strip from falling out of the guide groove 11 due to the shaking of the tail during cutting, a dovetail shape is set at one end of the guide groove 11 corresponding to the tail of the welding strip, and a limiting groove 13 extends along the guide groove 11 at one end corresponding to the head of the welding strip. The width of the guide groove 11 gradually narrows from the tail end to the head end, and the depth gradually decreases. Even if the tail of the welding strip shakes after being cut, it will not fall out of the guide groove 11. Furthermore, the slightly deformed welding strip can be reshaped when it is pulled out of the guide groove 11, which gradually narrows.

[0024] When the equipment is running at high speed, the welding strip is light and often deviates from the guide groove 11 due to high speed. In this embodiment, in order to prevent the welding strip from deviating from the guide groove 11 due to the high speed of the equipment after entering the guide groove 11, the filamentous material carrying device includes a sealing plate 20 and a carrying plate 10. The sealing plate 20 is slidably connected to the carrying plate 10 with a slide rail by a slider. The sealing plate 20 has a sealing plate 21 at the position corresponding to the limiting groove 12. By setting the sealing plate 20, the sealing plate 21 can cooperate with the limiting groove 12 to limit the position of the welding strip head.

[0025] When the welding strip is pulled out of the support plate 10, the sealing plate 21 needs to move to cancel the closed limiting groove 12 and wait for the welding strip to enter the support plate 10 again. Therefore, the filamentous material carrying device includes a telescopic power device fixed below the support plate 10 and connected to the sealing plate 20. In this embodiment, the telescopic power device is a cylinder 30. The movable end of the cylinder 30 is connected to the sealing plate 20. The setting of the cylinder 30 can drive the sealing plate 20 to move laterally relative to the support plate 10, thereby realizing the lateral movement of the sealing plate 21 relative to the limiting groove 12 and realizing the opening and closing of the limiting groove 12.

[0026] In this embodiment, during the process of the welding strip being pulled and moved by the welding strip traction device, in order to prevent the filamentous material carrying device from interfering with its movement, the filamentous material carrying device needs to first descend to move the welding strip to the designated position, and then rise to allow the welding strip to enter the guide groove 11. Therefore, the filamentous material carrying device is equipped with a lifting power device located below the carrying plate 10. The lifting power unit includes a driver, a lead screw module, a synchronous belt 48, a lifting side plate 46, and a connecting block 47. The driver includes a motor 40 and a drive wheel 41 mounted on the output shaft of the motor 40. The lead screw module includes a lead screw 42, a slide rail 43, a slider 44, and a driven wheel 45. In the lead screw module, two sets of slide rails 43 are vertically mounted on the lifting side plate 46. A bearing plate 10 is connected to the upper end of the connecting block 47. The connecting block 47 is slidably connected to the slide rails 43 mounted on the lifting side plate 46 through two sets of sliders 44 mounted on one side, enabling the bearing plate 10 to lift relative to the lifting side plate 46. The lead screw 42 is mounted below the connecting block 47, and the power end of the lead screw 42 is fixedly connected to the driven wheel 45. The driven wheel 45 is connected to the drive wheel 41 through the synchronous belt 48. When the motor 40 drives the drive wheel 41, it drives the driven wheel 45 to rotate. The driven wheel 45 drives the lead screw module to lift, thereby realizing the automatic lifting function of the filamentous material carrying device.

[0027] To ensure the contact accuracy between the solder strip and the cell grid lines during the pulling and moving process, it is necessary to follow the solder strip throughout the process to limit and support it. Therefore, the filament material carrying device is also equipped with a translational force device (not shown in the figure) located below the lifting power device. In this embodiment, the translational force device adopts an open synchronous belt module. The translational force device can make the filament material carrying device translate in the direction of the cell grid lines, thereby achieving full-process limit and support of the solder strip.
