During battery cold plate production, insulating and anti-corrosion coatings are typically applied to the cold plate surface using a spraying device to extend the cold plate's service life and ensure the efficient and safe operation of the battery thermal management system.

[0003] When spraying a cold plate, a fixing assembly within the spraying device secures the cold plate to a workbench before spraying. However, since different cold plate models require fixing assemblies of varying specifications, existing technologies require the manufacture of fixing assemblies of varying specifications to meet production needs.

DETAILED DESCRIPTION

[0028] The following is combined with Figure 1 -Attached Figure 8 This application is described in further detail.

[0029] Example 1

[0030] Example 1 of the present application discloses a universal automotive battery cold plate multi-size fixing assembly. Figure 1 and Figure 2As shown, the fixing assembly includes a base frame 1, a pair of first clamping devices 2, and a second clamping device 3. The first clamping device 2 includes a clamping frame 28 and a plurality of first rollers 23, and the first rollers 23 are rotatably connected to the clamping frame 28. The base frame 1 includes a plurality of connecting rods 12, and the plurality of connecting rods 12 are fixedly connected to form the base frame 1. The clamping frame 28 is provided with mounting holes for mounting bolts, and the clamping frame 28 is mounted on the connecting rods 12 via the bolts. By adjusting the position of the clamping frame 28, cold plates of different sizes can be clamped, thereby improving the versatility of the fixing assembly.

[0031] like Figure 2 and Figure 3 As shown, the second clamping device 3 includes a clamping block 31 and a pushing structure 32. The clamping block 31 is connected to the base frame 1. The pushing structure 32 includes a push plate support seat 321, a push plate 322, and a pushing mechanism 323. The pushing mechanism 323 includes a push driving member 3231, a rack 3232, a slide 3233, and a slider 3234. The body of the push driving member 3231 is fixedly connected to the push plate support seat 321. The output end of the push driving member 3231 is fixedly connected to a gear. The rack 3232 is fixedly connected to the push plate 322, and the gear meshes with the rack 3232. The slider 3234 is fixedly connected to the push plate 322, the slide groove 3233 is fixedly connected to the push plate support seat 321, the slider 3234 is slidably connected to the slide groove 3233, and through the cooperation of the rack 3232, the slider 3234 and the slide groove 3233, the push driving member 3231 can drive the push plate 322 to slide on the push plate support seat 321.

[0032] The implementation principle of a multi-size fixing assembly for a universal vehicle battery cold plate in Example 1 of the present application is as follows:

[0033] When the cold plate needs to be sprayed, the position of the clamping frame 28 is adjusted according to the size of the cold plate so that the two side ends of the cold plate abut against the first roller 23 respectively, thereby limiting the cold plate in one direction.

[0034] Then, the driving member 3231 is controlled to drive the pushing plate 322 to move, and the pushing plate 322 pushes the cold plate to abut against the clamping block 31 , thereby limiting the four sides of the cold plate and facilitating spraying.

[0035] Embodiment 1 of the present application utilizes the cooperation of the first clamping device 2 and the second clamping device 3, and can be applicable to fixing cold plates of different specifications during the spraying process, thereby reducing the cost of the production process.

[0036] Example 2

[0037] Example 2 of the present application discloses a universal automotive battery cold plate multi-size fixing assembly, such as Figure 4As shown, the fixing assembly includes a base frame 1 , a pair of first clamping devices 2 and a second clamping device 3 .

[0038] Specifically, such as Figure 4 and Figure 5 As shown, the first clamping device 2 includes a clamping drive 21, a connecting seat 22, a plurality of first rollers 23, a plurality of second rollers 24, a lifting drive 25 and a detection member 27. Among them, the connecting seat 22 includes a first connecting plate 221 and a second connecting plate 222. In this embodiment 2, the first clamping device 2 includes two clamping drives 21, the body of the clamping drive 21 is fixedly connected to the base frame 1, and the output end of the clamping drive 21 is rotatably connected to the second connecting plate 222. The second connecting plate 222 can be driven to move by the clamping drive 21. Preferably, the clamping drive 21 is an electric push rod. In addition, a guide seat 11 is fixedly connected to the base frame 1, and the output end of the clamping drive 21 is passed through the guide seat 11. The stability of the clamping drive 21 in the process of driving the second connecting plate 222 to move is improved by the guide seat 11.

[0039] Furthermore, if Figure 6 As shown, multiple lifting drive members 25 are mounted on the second connecting plate 222. Preferably, the lifting drive members 25 are electric push rods. The body of the lifting drive member 25 is fixedly connected to the second connecting plate 222, and the output end of the lifting drive member 25 is fixedly connected to the first connecting plate 221. Multiple guide rods 26 are fixedly connected to the second connecting plate 222. The guide rods 26 pass through the first connecting plate 221. The lifting drive member 25 can drive the first connecting plate 221 to slide on the guide rods 26. The first roller 23 and the second roller 24 are respectively rotatably connected to the first connecting plate 221. Through the cooperation of the clamping drive member 21 and the lifting drive member 25, the first roller 23 and the second roller 24 can be moved to abut the cold plate.

[0040] like Figure 5 As shown, the body of the detection member 27 is fixedly connected to the base frame 1, and the detection member 27 is electrically connected to the clamping drive member 21. In this second embodiment, the first clamping device 2 has two detection members 27. Preferably, the detection members 27 are distance sensors. The two detection members 27 respectively measure the distance to the side of the cold plate, thereby obtaining the inclination angle of the cold plate. This causes the output ends of the two clamping drive members 21 to move a specified distance, causing the entire connector 22 to rotate to match the inclination angle of the cold plate.

[0041] It should be noted that since the cold plate may tilt when placed on the base frame 1, it is necessary to adjust its position before spraying. During the adjustment process of the cold plate, the bottom surface of the cold plate contacts the base frame 1, which can easily cause wear on the cold plate and affect production quality. The present application utilizes the detection member 27 and the clamping drive member 21 to cooperate so that the connecting seat 22 moves at the same tilt angle as the cold plate, thereby clamping the cold plate when the first rollers 23 on both sides of the cold plate move to abut against the cold plate. After the first rollers 23 on both sides clamp the cold plate, the lifting drive member 25 drives the first connecting plate 221 to move, causing the second roller 24 to abut against the bottom surface of the cold plate and lift the cold plate to a height where it does not contact the base frame 1. After the cold plate is lifted, the clamping drive member 21 drives the connecting seat 22 to move and adjust the angle, thereby adjusting the orientation of the cold plate, reducing the possibility of wear caused by friction with the base frame 1 during the adjustment process of the cold plate from the tilted state.

[0042] like Figure 7 and Figure 8 As shown, the second clamping device 3 includes a clamping block 31 and a pushing structure 32. The clamping block 31 is connected to the base frame 1. The pushing structure 32 includes a push plate support seat 321, a push plate 322, and a pushing mechanism 323. The pushing mechanism 323 includes a push driving member 3231, a rack 3232, a slide 3233, and a slider 3234. The body of the push driving member 3231 is fixedly connected to the push plate support seat 321. The output end of the push driving member 3231 is fixedly connected to a gear. The rack 3232 is fixedly connected to the push plate 322, and the gear meshes with the rack 3232. The slider 3234 is fixedly connected to the push plate 322, the slide groove 3233 is fixedly connected to the push plate support seat 321, the slider 3234 is slidably connected to the slide groove 3233, and through the cooperation of the rack 3232, the slider 3234 and the slide groove 3233, the push driving member 3231 can drive the push plate 322 to slide on the push plate support seat 321.

[0043] After the two first clamping devices 2 clamp the cold plate and adjust its position, the driving member 3231 drives the pushing plate 322 to move, causing the pushing plate 322 to push the cold plate until it abuts the clamping block 31, thereby cooperating with the first clamping device 2 to achieve positioning of the cold plate on all sides. As the pushing plate 322 pushes the cold plate to move, the first roller 23 abuts the side of the cold plate, and the second roller 24 abuts the bottom of the cold plate. The first and second rollers 23 and 24 reduce the resistance of the cold plate during movement, thereby reducing the possibility of wear on the cold plate. At the same time, the cold plate is in an elevated state during movement, reducing the possibility of wear on the bottom of the cold plate from contact with the base frame 1 during movement. In addition, a buffer pad is installed on the clamping block 31 to provide cushioning when the cold plate contacts the clamping block 31, further reducing the possibility of wear on the cold plate.

[0044] like Figure 4 and Figure 7 As shown, the pushing mechanism 323 also includes a plurality of blanking assemblies 324, each comprising a blanking member 3241 and a telescopic mechanism, wherein the telescopic mechanism comprises a telescopic support seat 3242, a stop block 3243, and an elastic member 3244. The telescopic support seat 3242 is fixedly connected to the pushing plate 322, the stop block 3243 is slidably connected to the inner wall of the telescopic support seat 3242, and the ends of the elastic member 3244 are respectively fixedly connected to the stop block 3243 and the inner wall of the telescopic support seat 3242. In this embodiment 2, the blanking member 3241 is a suction cup having a certain degree of flexibility, and the elastic member 3244 is a spring.

[0045] When the cold plate is placed on the base frame 1, the cold plate first contacts the blanking piece 3241, causing the elastic piece 3244 to compress. The elastic piece 3244 can provide a buffering effect for the cold plate, reducing the possibility of wear and tear caused by the contact between the cold plate and the base frame 1. After the cold plate is sprayed, the blanking piece 3241 is pressed against the cold plate under the action of the elastic force of the elastic piece 3244, thereby improving the stability of the connection between the blanking piece 3241 and the cold plate. After the blanking piece 3241 absorbs the cold plate, the movement of the push plate 322 can drive the cold plate to move, thereby allowing the cold plate to move out of the range of the base frame 1, thereby facilitating the cold plate to enter the next production link.

[0046] The implementation principle of a multi-size fixing assembly for a universal vehicle battery cold plate in Example 2 of the present application is as follows:

[0047] When the cold plate is placed on the bottom frame 1 , the cold plate first contacts the blanking piece 3241 and gradually compresses the elastic piece 3244 .

[0048] After the cold plate is placed on the chassis 1, the detection member 27 detects the cold plate's tilt angle and controls the output ends of the two clamping drive members 21 to move a specified distance, thereby adjusting the tilt angle of the connecting seat 22 to that of the cold plate. The first roller 23 then moves to abut against the side of the cold plate. At this point, the second roller 24 is located on the underside of the cold plate.

[0049] When the first rollers 23 on either side of the cold plate come into contact with the plate, the plate is clamped. The lifting drive 25 then drives the first connecting plate 221 upward until the second rollers 24 come into contact with the underside of the cold plate, lifting the plate until it is no longer in contact with the base frame 1. After the cold plate is lifted a specified distance, freeing it from contact with the blanking member 3241, the clamping drive 21 moves a specified distance to adjust the position of the cold plate.

[0050] After the cold plate is positioned correctly, the push drive member 3231 drives the push plate 322 to move, and the push plate 322 pushes the cold plate into contact with the clamping block 31, thereby limiting the cold plate's periphery. Then, the lifting drive member 25 drives the first connecting plate 221 downward, placing the cold plate on the base frame 1. After the cold plate is placed on the base frame, spraying is performed.

[0051] After the cold plate is sprayed, the lifting drive 25 drives the first connecting plate 221 to move a specified distance, lifting the cold plate to a position that is not in contact with the base frame 1, and keeping the blanking member 3241 in contact with the bottom of the cold plate. At this time, the blanking member 3241 works to attract the bottom of the cold plate. At the same time, the push drive 3231 drives the push plate 322 to move. Driven by the blanking member 3241, the cold plate and the push plate 322 move out of the range of the base frame 1, thus facilitating the base frame 1 to enter the next production stage.

[0052] The second embodiment of the present application utilizes the cooperation of the first clamping device 2 and the second clamping device 3 to secure cold plates of different specifications during the spraying process, thereby improving the degree of automation in the cold plate production process and reducing production costs. Furthermore, the possibility of wear during the securing process is reduced, thereby improving the production quality of the cold plate.

[0053] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
