Description

Technical Field

[0001] The present application relates to a water-cooling plate manufacturing device, and in particular to a water-cooling plate laser cleaning machine. Background Art

[0002] The water-cooling plate is an important component of liquid cooling in the battery pack. The water-cooling plate in the related art includes a plate body and current collectors arranged at both ends of the plate body. During the manufacturing process of the water-cooling plate, a welding ring is put on the outer periphery of the plate body, and then the current collector is pressed to the end of the plate body. The water-cooling plate is then sent into a high-frequency welding machine, and the welding ring is heated to a preset temperature to melt it into a liquid state, and fill the joint between the current collector and the plate body, thereby welding the current collector and the plate body together. The weld surface between the current collector and the plate body needs to be polished to meet the corresponding process requirements, but manual processing is labor-intensive, time-consuming, and inefficient, and the polishing effect is not ideal. Summary of the Invention

[0003] In view of this, the present application provides a water-cooled plate laser cleaning machine that can perform laser cleaning on welds to improve work efficiency.

[0004] In order to achieve the above objectives, this application is implemented through the following technical solutions:

[0005] A water-cooling plate laser cleaning machine is characterized by comprising a machine platform, a clamping mechanism arranged on the machine platform for clamping the water-cooling plate and driving it to flip, a laser cleaning mechanism arranged on the machine platform for polishing the corresponding position of the water-cooling plate, and a transfer mechanism for sending the water-cooling plate to a position that can be clamped by the clamping mechanism or moving the water-cooling plate outward from the clamping position. During the flipping process of the water-cooling plate, the laser cleaning mechanism polishes all four sides of the water-cooling plate.

[0006] The above-mentioned water-cooling plate laser cleaning machine of the present application can send the water-cooling plate to the position of the clamping mechanism through the transfer mechanism. The clamping mechanism can clamp the water-cooling plate and flip it over. This laser cleaning mechanism can grind the four sides of the weld of the water-cooling plate, that is, the entire circle. Compared with manual operation, the work efficiency is high and the quality of the finished product is good.

[0007] In some embodiments, the transfer mechanism includes a longitudinally arranged transfer platform, a transfer linear module for driving the transfer platform to move horizontally, two transfer clamps respectively arranged at the longitudinal ends of the transfer platform for clamping the longitudinal ends of the water-cooled plate, and two or more lifting mechanisms arranged on the transfer platform; the transfer clamp has two fingers that can open and close in the transverse direction, and the lifting mechanism includes a lifting cylinder fixedly mounted on the bottom of the transfer platform and capable of vertical extension and contraction, and a top plate fixedly mounted on the piston rod of the lifting cylinder; when the top plate rises, it can push the water-cooled plate to move above the transfer platform so that the clamping mechanism can grasp it, and when the top plate descends, it can support the water-cooled plate and descend to its initial position. The transfer clamp is a pneumatic finger, and the linear module is mainly composed of a motor, a ball screw, and a linear guide assembly.

[0008] In some embodiments, there are two clamping mechanisms and they are arranged on both longitudinal sides of the transfer linear module, and the two clamping mechanisms are arranged opposite to each other. The clamping mechanism includes a first clamping platform, a clamping linear module for driving the first clamping platform to move longitudinally, a displacement platform fixedly mounted on the first clamping platform and capable of horizontal and vertical movement adjustment, a second clamping platform fixedly mounted on the slider of the displacement platform, a clamping claw rotatably connected to the second clamping platform, and a rotating motor for driving the clamping claw to rotate; the clamping claw has fingers that can be opened and closed up and down, and the two clamping claws respectively clamp the longitudinal ends of the water-cooling plate, and can be driven by the rotating motor to drive the water-cooling plate to flip.

[0009] In some embodiments, the number of the laser cleaning mechanisms is two and is arranged on one lateral side of the clamping mechanism. The two laser cleaning mechanisms are arranged opposite to each other in the longitudinal direction. The laser cleaning mechanism includes a first laser linear module for driving the laser head to move vertically up and down, and a second laser linear module for driving the first laser linear module to move longitudinally.

[0010] In some embodiments, the laser cleaning machine further includes two longitudinally opposed cleaning assemblies, disposed between the transfer mechanism and the clamping mechanism. The cleaning assemblies include a cleaning bracket fixed to the machine platform and two rows of brushes spaced apart from one another. When the transfer mechanism moves the water-cooling plate outward from the clamping position, the brushes move through the gap between the upper and lower rows of brushes, thereby cleaning debris from the corresponding portion of the water-cooling plate surface. The cleaning assemblies are stationary, and debris from the surface of the water-cooling plate can be cleaned by the brushes as the water-cooling plate moves outward.

[0011] In some embodiments, limit plates are provided on both longitudinal sides of the transfer mechanism, wherein the limit plates are mainly used to ensure that the water cooling plate is in a set position.

[0012] In some embodiments, a coding device is also provided on the machine platform for coding. Coding on the water-cooled plate facilitates later tracing.

[0013] It can be seen from the above technical solution that this application has at least the following advantages and positive effects:

[0014] The above-mentioned water-cooling plate laser cleaning machine of the present application can send the water-cooling plate to the position of the clamping mechanism through the transfer mechanism. The clamping mechanism can clamp the water-cooling plate and flip it over. This laser cleaning mechanism can grind the four sides of the weld of the water-cooling plate, that is, the entire circle. Compared with manual operation, the work efficiency is high and the quality of the finished product is good. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In order to make the purpose, technical solutions and advantages of this application clearer, this application will be further described in detail below with reference to the accompanying drawings. The terms used in the implementation methods of this application are only used to explain the specific embodiments of this application and are not intended to limit this application.

[0023] See also Figure 6When assembling the water-cooling plate 8, the welding ring 82 is inserted into the plate body 81 and then the current collector 83 is inserted. During the high-temperature heating process, the welding ring 82 melts, and the current collector 83 is welded to the plate body 81. The surface of the weld is rough and needs to be laser cleaned.

[0024] Based on the above, see Figures 1 to 5 The present invention provides a water-cooling plate laser cleaning machine, which is mainly used to clean the weld seams of the water-cooling plate 8. The machine comprises a platform 1, a clamping mechanism 2 disposed on the platform 1 for clamping the water-cooling plate 8 and driving its rotation, a laser cleaning mechanism 3 disposed on the platform 1 for polishing corresponding positions of the water-cooling plate 8, and a transfer mechanism 4 for delivering the water-cooling plate 8 to a position that can be clamped by the clamping mechanism 2 or for moving the water-cooling plate 8 outward from the clamping position. During the rotation of the water-cooling plate 8, the laser cleaning mechanism 3 polishes all four sides of the water-cooling plate 8.

[0025] The laser cleaning machine can send the water-cooling plate 8 to the position of the clamping mechanism 2 through the transfer mechanism 4. The clamping mechanism 2 can clamp the water-cooling plate 8 and flip it over. The laser cleaning mechanism 3 can grind the four sides of the weld of the water-cooling plate 8, that is, the entire circle. Compared with manual operation, the work efficiency is high and the quality of the finished product is good.

[0026] The transfer mechanism 4 includes a longitudinally arranged transfer platform 41, a transfer linear module 42 for driving the transfer platform 41 to move horizontally, two transfer clamps 43 respectively arranged at the longitudinal ends of the transfer platform 41 for clamping the longitudinal ends of the water-cooling plate 8, and two or more lifting mechanisms arranged on the transfer platform 41; the transfer clamp 43 has two fingers that can open and close in the horizontal direction, and the lifting mechanism includes a lifting cylinder 44 fixedly mounted on the bottom of the transfer platform 41 and capable of vertical extension and contraction, and a lifting plate 45 fixedly mounted on the piston rod of the lifting cylinder 44; when the lifting plate 45 rises, it can push the water-cooling plate to move above the transfer platform 41 so that the clamping mechanism 2 can grasp it, and when the lifting plate 45 descends, it can support the water-cooling plate and descend to its initial position. The transfer clamp 43 is a pneumatic finger, and the linear module is mainly composed of a motor, a ball screw, and a linear guide assembly.

[0027] There are two clamping mechanisms 2, which are arranged on both longitudinal sides of the transfer linear module 42, and the two clamping mechanisms 2 are arranged opposite each other. The clamping mechanisms 2 include a first clamping platform 21, a clamping linear module 22 for driving the longitudinal movement of the first clamping platform 21, a displacement platform 23 fixedly mounted on the first clamping platform 21 and capable of horizontal and vertical movement adjustment, a second clamping platform 24 fixedly mounted on the slider of the displacement platform 23, a clamping jaw 25 rotatably connected to the second clamping platform 24, and a rotary motor 26 for driving the clamping jaw 25 to rotate; the clamping jaw 25 has fingers that can be opened and closed up and down, and the two clamping jaws 25 respectively clamp the longitudinal ends of the water-cooling plate 8. Driven by the rotary motor 26, the water-cooling plate 8 can be driven to flip. The displacement platform 23 is also called the xy-axis displacement platform 23, and the displacement platform 23 is mainly used for manually fine-tuning the second clamping platform 24.

[0028] Two laser cleaning mechanisms 3 are positioned on either side of the clamping mechanism 2, facing each other longitudinally. Each laser cleaning mechanism 3 includes a laser head 33, a first laser linear module 31 for driving the vertical movement of the laser head 33, and a second laser linear module 32 for driving the longitudinal movement of the first laser linear module 31. Because both ends of the water-cooled plate 8 have welds, the two laser cleaning machines can operate simultaneously, increasing processing efficiency.

[0029] The laser cleaning machine also includes two cleaning assemblies 5 arranged longitudinally opposite each other. The cleaning assemblies 5 are arranged between the transfer mechanism 4 and the clamping mechanism 2. The cleaning assemblies 5 include a cleaning bracket 51 fixed to the machine 1 and two rows of brushes 52 spaced apart from each other. When the transfer mechanism 4 moves the water-cooling plate 8 outward from the clamping position, it moves through the gap between the upper and lower rows of brushes 52, so that the brushes 52 can clean the surface debris of the corresponding parts of the water-cooling plate 8. The cleaning assemblies 5 are fixed, and the brushes 52 can clean the surface debris of the water-cooling plate 8 as the water-cooling plate 8 moves outward.

[0030] Limiting baffles 6 are also provided on both longitudinal sides of the transfer mechanism 4. The limiting baffles are mainly used to ensure that the water cooling plate 8 is in a set position.

[0031] A coding device for coding is also provided on the machine 1. Coding on the water-cooled plate 8 facilitates tracing back later.

[0032] The following briefly describes the working process and usage of the water-cooled plate laser cleaning machine in the above embodiment:

[0033] Place the water-cooled plate 8 on the transfer platform 41, with both ends supporting the limit plates. The two transfer clamps 43 clamp the water-cooled plate 8. The transfer linear module 42 moves to drive the water-cooled plate 8 to move to the clamping position. The upper cylinder moves upward, and the top plate 45 lifts the water-cooled plate 8. Then the two clamping mechanisms 2 move synchronously. The clamping linear module 22 drives the clamping jaws 25 to move toward the water-cooled plate 8. The two fingers of the clamping jaws 25 close up and down to clamp the water-cooled plate 8. Driven by the first linear module and the second linear module, the laser head 33 of the laser cleaning mechanism 3 moves to the top of the weld of the water-cooled plate 8 and performs laser cleaning on one surface. After one surface is completed, the clamping jaws 25 rotate to drive the water-cooled plate 8 to turn over, and laser cleaning continues until all four surfaces are cleaned. Then the top plate 45 rises to catch the water-cooled plate 8, the clamping jaws 25 release the water-cooled plate 8, the water-cooled plate 8 descends to the transfer platform 41, the transfer jaws 43 clamp the water-cooled plate 8 again, and move outward to the coding device 7. After the coding is completed, it continues to reset outward, passes through the brush body 52 of the cleaning component 5, removes the surface debris, returns to the initial position, removes the water-cooled plate 8, and completes the laser cleaning work.
