Description

Technical Field

[0001] This application relates to equipment for manufacturing water-cooled plates, and more particularly to a dust collection mechanism for a laser cleaning machine and a laser cleaning machine for water-cooled plates. Background Technology

[0002] The descriptions in this section provide background information related to this disclosure only and do not constitute prior art. A water-cooled plate is a crucial component of liquid cooling in a battery pack. The water-cooled plate includes a plate body and current collectors located at both ends of the plate body. During manufacturing, a welding ring is fitted around the outer periphery of the plate body, and the current collectors are pressed to the ends of the plate body. The water-cooled plate is then fed into a high-frequency welding machine, where the welding rings are heated to a preset temperature, melting them into a liquid state and filling the seam between the current collectors and the plate body, thus welding the current collectors and the plate body together. The weld surface between the current collectors and the plate body needs to be polished to meet relevant process requirements. In related technologies, water-cooled plate cleaning machines use laser polishing, but the dust generated during polishing is directly exposed to the natural environment, affecting the production environment. Summary of the Invention

[0003] In view of this, this application provides a dust collection mechanism for a laser cleaning machine and a water-cooled plate laser cleaning machine, which can reduce the diffusion of dust during laser cleaning.

[0004] To achieve the above objectives, this application employs the following technical solution:

[0005] A dust collection mechanism for a laser cleaning machine is characterized by comprising: a laser movable plate, a laser lifting module connected to the laser movable plate for driving the laser movable plate to move up and down, and at least one laser unit fixedly mounted on the laser movable plate; each laser unit includes a laser lens fixedly mounted on the laser movable plate and a dust collection hood fixedly mounted on the laser movable plate and located below the laser lens, the dust collection hood opening downwards so that it covers a water-cooled plate when the laser movable plate descends, and a laser light inlet is provided at the top of the dust collection hood; clearance notches are provided on the left and right sides of the dust collection hood to prevent the water-cooled plate from interfering with the dust collection hood during the flipping process; a suction port is also provided on the dust collection hood, and the suction port is also connected to a negative pressure dust collection system for dust collection.

[0006] The dust collection mechanism of the laser cleaning machine described in this application has a dust collection hood set below the laser lens. When the dust collection hood descends, it can cover the part of the water-cooled plate to be cleaned in a relatively small space. In this way, the dust cleaned off by the laser lens is not easily dispersed into the air. Finally, it is adsorbed by the negative pressure dust collection system, which can reduce the diffusion of dust.

[0007] In some embodiments, the dust collection mechanism also includes a laser left and right module for driving the laser lifting module to move left and right, and the number of laser units on the laser movable plate is two and they are spaced apart in the front-back direction.

[0008] This application also provides a water-cooled plate laser cleaning machine, which has the dust collection mechanism of the aforementioned laser cleaning machine. The machine is characterized by: a frame and a conveyor platform mechanism mounted on the frame for forward conveying of water-cooled plates. The conveyor platform mechanism is provided with at least two positioning blocks spaced apart front to back for positioning and placing the water-cooled plates. The water-cooled plate laser cleaning machine also includes two clamping mechanisms respectively located on the left and right sides of the conveyor platform mechanism for clamping the two ends of the water-cooled plates. Each clamping mechanism includes two clamping rotating components spaced apart front to back. One clamping rotating component clamps the first water-cooled plate and can drive it to rotate, and the other clamping rotating component clamps the second water-cooled plate and can drive it to rotate. A mounting frame is also fixedly mounted on the frame. Two sets of dust collection mechanisms are installed on the left and right sides of the mounting frame for cleaning the left and right ends of the two water-cooled plates respectively. Two laser units in each set of dust collection mechanisms are located above the two clamping rotating components for cleaning the first and second water-cooled plates respectively.

[0009] This water-cooled plate laser cleaning machine has two stations, allowing simultaneous cleaning of both the first and second water-cooled plates. Compared to single-station cleaning machines, it is more efficient and has a faster cycle time. The first clamping and rotating assembly grips the first water-cooled plate, while the corresponding first laser unit cleans its front side. The first clamping and rotating assembly then rotates the first water-cooled plate 90 degrees, and the corresponding laser unit cleans its side. Finally, the first clamping and rotating assembly rotates the first water-cooled plate another 90 degrees to flip it over, and then the first water-cooled plate is conveyed forward via a conveyor mechanism. The first water-cooled plate from the previous process enters the second station as the second water-cooled plate. The second clamping and rotating assembly grips the second water-cooled plate, and the corresponding second laser unit cleans its back side. The second clamping and rotating assembly then rotates the second water-cooled plate 90 degrees, and the second laser unit cleans its other side.

[0010] In some embodiments, the clamping mechanism includes a clamping slide rail extending in the left-right direction and fixedly mounted on the frame, a clamping slide table slidably connected to the clamping slide rail in the left-right direction, a clamping linear module for moving the clamping slide table left and right, a clamping lifting platform connected to the clamping slide table in a vertical lifting manner, and a clamping lifting cylinder for driving the clamping lifting platform to move up and down. Two clamping rotating components are spaced apart on the clamping lifting platform in the front-back direction. The clamping rotating components include a first gripper cylinder that can open and close up and down for clamping the upper and lower surfaces of the corresponding water-cooling plate, and a rotary motor mounted on the clamping lifting platform for driving the first gripper cylinder to rotate.

[0011] In some embodiments, the clamping slide is further fixedly equipped with two second gripper cylinders that can open and close back and forth to clamp the front and rear sides of the water-cooling plate. These second gripper cylinders are used to position the front and rear sides of the water-cooling plate.

[0012] In some embodiments, the conveying platform mechanism includes a conveying slide rail extending in the front-to-back direction and fixedly mounted on a frame, a conveying slide table slidably connected to the conveying slide rail in the front-to-back direction, a conveying linear module for driving the conveying slide table to move back and forth, a conveying lifting platform slidably connected to the conveying slide table in the vertical direction, and a conveying lifting cylinder for driving the conveying lifting platform to move up and down, wherein the positioning block is fixedly mounted on the conveying lifting platform.

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

[0014] This application discloses a dust collection mechanism for a laser cleaning machine and a laser cleaning machine for water-cooled plates. By setting a dust collection hood below the laser lens, the dust collection hood can cover the part of the water-cooled plate to be cleaned in a relatively small space when it descends. In this way, the dust cleaned off by the laser lens is not easily dispersed into the air. Finally, it is adsorbed by the negative pressure dust collection system, which can reduce the diffusion of dust. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of this application clearer, the application will be described in further detail below with reference to the accompanying drawings. The terminology used in the embodiments section of this application is only for explaining specific embodiments and is not intended to limit the application.

[0022] See Figures 1 to 5 This application provides a water-cooled plate laser cleaning machine, including a frame 1, a dust collection mechanism 5, and a conveying platform mechanism 2 mounted on the frame 1 for forward conveying of water-cooled plates. The conveying platform mechanism 2 is provided with at least two positioning blocks 25 for positioning and placing water-cooled plates respectively. The water-cooled plate laser cleaning machine also includes two clamping mechanisms 3 respectively disposed on the left and right sides of the conveying platform mechanism 2 for clamping the two ends of the water-cooled plates respectively. Each clamping mechanism 3 includes two clamping rotation components 36, one clamping rotation component 36 for clamping the first water-cooled plate and driving it to rotate, and the other clamping rotation component 36 for clamping the second water-cooled plate and driving it to rotate.

[0023] The vacuuming mechanism 5 includes a laser movable plate 51, a laser lifting module 52 connected to the laser movable plate 51 for driving the laser movable plate 51 to move up and down, and at least one laser unit 53 fixedly installed on the laser movable plate 51. Each laser unit 53 includes a laser lens 531 fixedly installed on the laser movable plate 51 and a vacuum hood 532 fixedly installed on the laser movable plate 51 and located below the laser lens 531. The vacuum hood 532 opens downward so that it covers the water-cooled plate when the laser movable plate 51 descends. A laser light inlet 5321 is provided on the top of the vacuum hood 532. Avoidance notches 5322 are provided on the left and right sides of the vacuum hood 532 to prevent the water-cooled plate from interfering with the vacuum hood 532 during the flipping process. A suction port 5323 is also provided on the vacuum hood 532, and the suction port 5323 is also connected to a negative pressure vacuuming system for vacuuming. The dust collection mechanism 5 also includes a laser left and right module 54 for driving the laser lifting module 52 to move left and right, and the laser unit 53 on the laser movable plate 51 is two and is arranged at intervals along the front and back direction.

[0024] A mounting bracket 4 is also fixedly installed on the frame 1. Two dust collection mechanisms 5 are installed on the mounting bracket 4 for cleaning both ends of the water flow plate respectively. The two laser units 53 in the dust collection mechanism 5 are located above the two clamping and rotating components 36 respectively for cleaning the first water cooling plate and the second water cooling plate respectively.

[0025] By setting a dust collection hood 532 below the laser lens 531, the dust collection hood 532 can cover the part of the water-cooled plate to be cleaned in a relatively small space when it descends. In this way, the dust cleaned off by the laser lens 531 is not easily dispersed into the air. Finally, it is adsorbed by the negative pressure dust collection system, which can reduce the spread of dust.

[0026] This water-cooled plate laser cleaning machine has two stations, allowing simultaneous cleaning of both the first and second water-cooled plates. Compared to single-station cleaning machines, it is more efficient and has a faster cycle time. The first clamping and rotating assembly 36 grips the first water-cooled plate, while the corresponding first laser unit 53 cleans its front side. The first clamping and rotating assembly 36 then rotates the first water-cooled plate 90 degrees, and the corresponding laser unit 53 cleans its side. Finally, the first clamping and rotating assembly 36 rotates the first water-cooled plate another 90 degrees to flip it over. The first water-cooled plate is then conveyed forward by the conveyor mechanism 2, becoming the second water-cooled plate in the second station. The second clamping and rotating assembly 36 grips the second water-cooled plate, and the corresponding second laser unit 53 cleans its back side. The second clamping and rotating assembly 36 then rotates the second water-cooled plate 90 degrees, and the second laser unit 53 cleans its other side.

[0027] The clamping mechanism 3 includes a clamping slide rail 31 extending in the left-right direction and fixedly mounted on the frame 1, a clamping slide 32 slidably connected to the clamping slide rail 31 in the left-right direction, a clamping linear module 33 for driving the clamping slide 32 to move left and right, a clamping lifting platform 34 connected to the clamping slide 32 in a vertical lifting manner, and a clamping lifting cylinder for driving the clamping lifting platform 34 to move up and down. Two clamping rotating components 36 are spaced apart on the clamping lifting platform 34 in the front-back direction. The clamping rotating components 36 include a first gripper cylinder 361 that can open and close up and down for clamping the upper and lower surfaces of the water-cooled plate, and a rotary motor 362 mounted on the clamping lifting platform 34 for driving the first gripper cylinder 361 to rotate.

[0028] Two second gripper cylinders 37, which can open and close back and forth, are also fixedly installed on the clamping slide 32 to clamp the front and rear sides of the water-cooling plate. The second gripper cylinders 37 are used to position the front and rear sides of the water-cooling plate.

[0029] The conveying platform mechanism 2 includes a conveying slide rail 21 extending in the front-to-back direction and fixedly mounted on the frame 1, a conveying slide 22 slidably connected to the conveying slide rail 21 in the front-to-back direction, a conveying linear module 23 for driving the conveying slide 22 to move back and forth, a conveying lifting platform 24 slidably connected to the conveying slide 22 in the vertical direction, and a conveying lifting cylinder 26 for driving the conveying lifting platform 24 to move up and down. A positioning block 25 is fixedly mounted on the conveying lifting platform 24.

[0030] The following is a brief description of the working process and usage method of the above embodiments:

[0031] Several water-cooled plates are placed on the positioning block 25 of the conveyor mechanism 2. The conveyor lifting platform 24, driven by the conveyor lifting cylinder 26, lifts the water-cooled plates, and the conveyor linear module 23 moves the conveyor lifting platform 24 forward one station. The clamping slides 32 of the two clamping mechanisms 3 move along the clamping slide rail 31 towards the two ends of the water-cooled plates, that is, the two clamping slides 32 move closer to each other. The conveyor lifting platform 24 descends, and the two second gripper cylinders 37 of the clamping slides 32 clamp the first water-cooled plate and the second water-cooled plate respectively. The first gripper cylinder 361 closes up and down to clamp the upper and lower surfaces of the water-cooled plate. The laser unit 53 descends to clean the weld position on the upper surface of the water-cooled plate. After cleaning, the second gripper cylinder 37 releases the water-cooled plate, the clamping lifting platform 34 rises, and the first gripper cylinder 361 rotates 90 degrees to face the side of the water-cooled plate upwards. The laser unit 53 cleans the side of the water-cooled plate. The first gripper cylinder 361 in the first station also flips the water-cooled plate so that the second station can clean the reverse side of the water-cooled plate. The first station only cleans the front and one side, while the second station cleans the back and the other side.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the embodiments of this application, and are not intended to limit them; although the embodiments of this application have been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
