Description

Technical Field

[0001] This application relates to the technical field of battery cold plate spraying apparatus, and in particular to a multi-size fixing assembly for a general automotive battery cold plate. Background Technology

[0002] Battery cooling plates are key components in the battery thermal management system of new energy vehicles, used to maintain the temperature stability within the battery pack and ensure that the battery operates within its optimal temperature range. During the production of battery cooling plates, insulating and anti-corrosion coatings are typically applied to the surface using a spraying device. This extends the lifespan of the cooling plate and ensures the efficient operation and safety of the battery thermal management system.

[0003] When spraying cold-rolled steel sheets, the sheets are fixed to the worktable using a fixing component within the spraying device before spraying. However, since different models of cold-rolled steel sheets require fixing components of different specifications, the existing technology requires the manufacture of fixing components of different specifications to meet production needs. This increases production costs, and also reduces production efficiency during the replacement of fixing components. Summary of the Invention

[0004] To improve the versatility of cold plate fixing components, this application provides a multi-size fixing component for general automotive battery cold plates.

[0005] This application provides a multi-size mounting assembly for a general-purpose automotive battery cooling plate, which adopts the following technical solution:

[0006] A multi-size fixing assembly for a general-purpose automotive battery cold plate includes a base frame, a pair of first clamping devices and a second clamping device, wherein the cold plate is placed on the base frame.

[0007] The first clamping device includes a clamping drive, a connecting seat, and a plurality of first rollers; the clamping drive is connected to the base frame, and the plurality of first rollers are rotatably mounted on the connecting seat; the clamping drive drives the connecting seat to move, so that the first rollers abut against the side end of the cold plate; two first clamping devices cooperate to clamp the cold plate;

[0008] The second clamping device includes a clamping block and a pushing structure. The clamping block is connected to the base frame, and the pushing structure is disposed on the base frame. After the two first clamping devices clamp the cold plate, the pushing structure pushes the cold plate to move until it abuts against the clamping block.

[0009] By adopting the above technical solution, the clamping drive unit drives the connecting seat to move, causing the first roller to abut against the side end of the cold plate, thereby clamping the cold plate. After the cold plate is clamped by the two first clamping devices, the pushing structure pushes the cold plate to abut against the clamping block, thereby limiting the position of the cold plate around its perimeter. Through the cooperation of the first clamping device and the second clamping device, the fixing component of this application can be adapted to fix cold plates of different specifications, thereby reducing production costs.

[0010] Optionally, the pushing structure includes a push plate support, a push plate, and a pushing mechanism. The push plate support is connected to the base frame, the push plate is slidably connected to the push plate support, and the pushing mechanism is disposed on the push plate support. The pushing mechanism drives the push plate to move, so that the push plate pushes the cold plate.

[0011] By adopting the above technical solution, the pushing mechanism can drive the pushing plate to slide on the base frame, thereby enabling the pushing plate to move the cold plate.

[0012] Optionally, the pushing mechanism includes a pushing drive component, a rack, a slide groove, and a slider. The pushing drive component is connected to the push plate support, the slide groove is connected to the push plate support, the slider is connected to the push plate, the slide groove is slidably connected to the slider, the rack is connected to the push plate, and the pushing drive component is drively connected to the rack.

[0013] By adopting the above technical solution, the cooperation of the rack, the slider and the groove enables the push drive to drive the push plate to slide on the push plate support.

[0014] Optionally, the pushing structure further includes multiple feeding components, which are disposed on the pushing plate; the feeding components abut against and attract the cold plate, so that the cold plate moves with the pushing plate.

[0015] By adopting the above technical solution, when the cold plate needs to be unloaded after spraying, the unloading component contacts the cold plate and drives the cold plate out of the base frame, thereby unloading.

[0016] Optionally, the feeding assembly includes a feeding component and a telescopic mechanism, the telescopic mechanism being disposed on the push plate; the cold plate abuts against the feeding component, causing the telescopic mechanism to compress.

[0017] By adopting the above technical solution, under the elastic force of the telescopic mechanism, the unloading component is pressed against the cold plate, thereby improving the stability of the connection between the unloading component and the cold plate. Simultaneously, when the base plate is placed on the base frame, the telescopic mechanism compresses after the cold plate contacts the unloading component, providing cushioning for the cold plate and reducing the possibility of wear when the cold plate contacts the base frame.

[0018] Optionally, the telescopic mechanism includes a telescopic support base, a limiting block, and an elastic element. The limiting block is connected to the unloading component and is slidably connected to the inner wall of the telescopic support base. The two ends of the elastic element are respectively connected to the limiting block and the inner wall of the telescopic support base.

[0019] By adopting the above technical solution, when the cold plate comes into contact with the unloading part, the limiting block moves to compress the elastic element, thereby achieving buffering of the cold plate.

[0020] Optionally, the first clamping device further includes a lifting drive component, the connecting seat includes a first connecting plate and a second connecting plate, the first connecting plate and the second connecting plate are slidably connected, the first roller is rotatably connected to the first connecting plate, and the lifting drive component is disposed on the second connecting plate; the lifting drive component drives the first connecting plate to move, so that the first connecting plate drives the cold plate to move vertically.

[0021] By adopting the above technical solution, the lifting drive component drives the first connecting plate to move, thereby lifting the cold plate and reducing the possibility of wear caused by the surface of the cold plate contacting the base frame when the pushing plate pushes the cold plate.

[0022] Optionally, a second roller is rotatably connected to the first connecting plate, and the second roller abuts against the bottom surface of the cold plate.

[0023] By adopting the above technical solution, when the second roller moves to the bottom of the cold plate, it moves with the first connecting plate to lift the cold plate. At this time, when the push plate pushes the cold plate, the second roller reduces the possibility of the cold plate coming into contact with the first connecting plate and causing wear.

[0024] Optionally, the first clamping device further includes a detection element, the output end of the clamping drive element is rotatably connected to the connecting seat, and the detection element is electrically connected to the clamping drive element; the detection element detects the tilt angle of the side end of the cold plate, so that the clamping drive element drives the connecting seat to rotate to adapt to the tilt angle of the side end of the cold plate.

[0025] By adopting the above technical solution, when the cold plate is placed on the base frame, the detection component can detect the tilt angle of the side end of the cold plate. Since the cold plate may tilt when placed on the base frame, the clamping drive component drives the connecting seat to rotate to adapt to the tilt angle of the side end of the cold plate. This allows for clamping and lifting of the cold plate in a tilted state. Furthermore, after the cold plate is lifted, the clamping drive component adjusts the position of the cold plate, reducing the possibility of wear caused by friction with the base frame during the adjustment process from a tilted state.

[0026] Optionally, the clamping block is provided with a buffer pad.

[0027] By adopting the above technical solution, the buffer pad can buffer when the cold plate comes into contact with the clamping block, thereby reducing the possibility of wear on the cold plate.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] 1. The clamping drive unit drives the connecting seat to move, causing the first roller to abut against the end side of the cold plate, thereby clamping the cold plate. After the cold plate is clamped by the two first clamping devices, the pushing structure pushes the cold plate to abut against the clamping block, thereby limiting the position of the cold plate around its perimeter. Through the cooperation of the first and second clamping devices, the fixing component of this application can be used to fix cold plates of different specifications, thereby reducing production costs;

[0030] 2. The first connecting plate is moved by the lifting drive component, thereby lifting the cold plate and reducing the possibility of wear caused by the cold plate surface contacting the base frame when the push plate pushes the cold plate;

[0031] 3. By cooperating with the detection component and the clamping drive component, when the cold plate is placed on the base frame, the detection component can detect the tilt angle of the side end of the cold plate. Since the cold plate may tilt when placed on the base frame, the clamping drive component drives the connecting seat to rotate to adapt to the tilt angle of the side end of the cold plate. This allows for clamping and lifting of the cold plate in a tilted state. After the cold plate is lifted, the clamping drive component adjusts the position of the cold plate, reducing the possibility of wear caused by friction with the base frame during the adjustment process from a tilted state.

[0041] The following is in conjunction with the appendix Figure 1 -Appendix Figure 8 This application will be described in further detail.

[0042] Example 1

[0043] Embodiment 1 of this application discloses a multi-size fixing assembly for a general-purpose automotive battery cooling plate. For example... 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 multiple first rollers 23, with the first rollers 23 rotatably connected to the clamping frame 28. The base frame 1 includes multiple connecting rods 12, which are fixedly connected to form the base frame 1. Mounting holes are provided on the clamping frame 28 for mounting bolts, and the clamping frame 28 is mounted on the connecting rods 12 by bolts. By adjusting the position of the clamping frame 28, cold-rolled plates of different sizes can be clamped, improving the versatility of the fixing assembly.

[0044] like Figure 2 and Figure 3 As shown, the second clamping device 3 includes a clamping block 31 and a pushing structure 32, with the clamping block 31 connected to the base frame 1. The pushing structure 32 includes a push plate support 321, a push plate 322, and a pushing mechanism 323. The pushing mechanism 323 includes a pushing drive 3231, a rack 3232, a slide groove 3233, and a slider 3234. The body of the pushing drive 3231 is fixedly connected to the push plate support 321, and a gear is fixedly connected to the output end of the pushing drive 3231. 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 321, and the slider 3234 is slidably connected to the slide groove 3233. Through the cooperation of the rack 3232, the slider 3234 and the slide groove 3233, the push drive 3231 can drive the push plate 322 to slide on the push plate support 321.

[0045] The implementation principle of a multi-size fixing assembly for a general-purpose automotive battery cold plate in Embodiment 1 of this application is as follows:

[0046] When the cold plate needs to be sprayed, the position of the clamp 28 is adjusted according to the size of the cold plate so that the two sides of the cold plate abut against the first roller 23 respectively, thereby limiting the cold plate in one direction.

[0047] Then, the push drive component 3231 drives the push plate 322 to move. The push plate 322 pushes the cold plate to abut against the clamping block 31, thereby limiting the cold plate around its perimeter and facilitating spraying.

[0048] Embodiment 1 of this application utilizes the cooperation of the first clamping device 2 and the second clamping device 3 to fix cold plates of different specifications during the spraying process, thereby reducing the cost in the production process.

[0049] Example 2

[0050] Embodiment 2 of this application discloses a multi-size fixing assembly for a general-purpose automotive battery cooling plate, 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.

[0051] Specifically, such as Figure 4 and Figure 5 As shown, the first clamping device 2 includes a clamping drive component 21, a connecting seat 22, multiple first rollers 23, multiple second rollers 24, a lifting drive component 25, and a detection component 27. 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 drive components 21. The body of the clamping drive component 21 is fixedly connected to the base frame 1, and the output end of the clamping drive component 21 is rotatably connected to the second connecting plate 222. The clamping drive component 21 can drive the second connecting plate 222 to move. Preferably, the clamping drive component 21 is an electric push rod. Furthermore, a guide seat 11 is fixedly connected to the base frame 1, and the output end of the clamping drive component 21 passes through the guide seat 11. The guide seat 11 improves the stability of the clamping drive component 21 during the movement of the second connecting plate 222.

[0052] Furthermore, such as Figure 6 As shown, multiple lifting drive components 25 are mounted on the second connecting plate 222. Preferably, the lifting drive component 25 is an electric push rod. The body of the lifting drive component 25 is fixedly connected to the second connecting plate 222, and the output end of the lifting drive component 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, and the lifting drive component 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 rotatably connected to the first connecting plate 221, respectively. Through the cooperation of the clamping drive component 21 and the lifting drive component 25, the first roller 23 and the second roller 24 can move to abut against the cold plate.

[0053] like Figure 5 As shown, the body of the detection element 27 is fixedly connected to the base frame 1, and the detection element 27 is electrically connected to the clamping drive element 21. In this embodiment 2, the first clamping device 2 has two detection elements 27, preferably, the detection element 27 is a distance sensor. The two detection elements 27 respectively measure the distance to the side end of the cold plate, thereby obtaining the tilt angle of the cold plate, so that the output ends of the two clamping drive elements 21 move a specified distance respectively, so that the connecting seat 22 rotates as a whole to adapt to the tilt angle of the side end of the cold plate.

[0054] It should be noted that since the cold plate may tilt when placed on the base frame 1, its position needs to be adjusted before spraying. During the adjustment process, the bottom surface of the cold plate comes into contact with the base frame 1, which can easily cause wear and affect production quality. This application utilizes the cooperation of the detection component 27 and the clamping drive component 21 to move the connecting seat 22 at the same tilt angle as the cold plate, thereby clamping the cold plate when the first rollers 23 on both sides move to abut against it. After the first rollers 23 on both sides clamp the cold plate, the lifting drive component 25 drives the first connecting plate 221 to move, so that the second roller 24 abuts against the bottom surface of the cold plate and lifts the cold plate to a height where it does not contact the base frame 1. After the cold plate is lifted, the clamping drive component 21 drives the connecting seat 22 to move and adjust the angle, thereby adjusting the orientation of the cold plate and reducing the possibility of wear caused by friction with the base frame 1 during the adjustment process from a tilted state.

[0055] like Figure 7 and Figure 8 As shown, the second clamping device 3 includes a clamping block 31 and a pushing structure 32, with the clamping block 31 connected to the base frame 1. The pushing structure 32 includes a push plate support 321, a push plate 322, and a pushing mechanism 323. The pushing mechanism 323 includes a pushing drive 3231, a rack 3232, a slide groove 3233, and a slider 3234. The body of the pushing drive 3231 is fixedly connected to the push plate support 321, and a gear is fixedly connected to the output end of the pushing drive 3231. 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 321, and the slider 3234 is slidably connected to the slide groove 3233. Through the cooperation of the rack 3232, the slider 3234 and the slide groove 3233, the push drive 3231 can drive the push plate 322 to slide on the push plate support 321.

[0056] After the two first clamping devices 2 clamp and adjust the position of the cold plate, the drive member 3231 drives the push plate 322 to move, causing the push plate 322 to push the cold plate until it abuts against the clamping block 31, thereby cooperating with the first clamping devices 2 to limit the cold plate around its perimeter. During the process of the push plate 322 pushing the cold plate, the first roller 23 abuts against the side end of the cold plate, and the second roller 24 abuts against the bottom of the cold plate. The first roller 23 and the second roller 24 reduce the resistance of the cold plate during the movement, thereby reducing the possibility of cold plate wear. At the same time, the cold plate is in a raised state during the movement, reducing the possibility of the bottom of the cold plate contacting the base frame 1 and causing wear. In addition, a buffer pad is installed on the clamping block 31, which can cushion the contact between the cold plate and the clamping block 31, thereby further reducing the possibility of cold plate wear.

[0057] like Figure 4 and Figure 7 As shown, the pushing mechanism 323 also includes multiple feeding components 324. Each feeding component 324 includes a feeding part 3241 and a telescopic mechanism. The telescopic mechanism includes a telescopic support base 3242, a limiting block 3243, and an elastic element 3244. The telescopic support base 3242 is fixedly connected to the pushing plate 322, the limiting block 3243 is slidably connected to the inner wall of the telescopic support base 3242, and the two ends of the elastic element 3244 are fixedly connected to the limiting block 3243 and the inner wall of the telescopic support base 3242, respectively. In this embodiment 2, the feeding part 3241 is a suction cup with a certain degree of flexibility, and the elastic element 3244 is a spring.

[0058] During the placement of the cold plate onto the base frame 1, the cold plate first contacts the unloading component 3241, compressing the elastic component 3244. The elastic component 3244 provides cushioning, reducing the possibility of wear between the cold plate and the base frame 1. After the cold plate is coated, the unloading component 3241 holds the cold plate against the elastic component 3244, improving the stability of the connection between the unloading component 3241 and the cold plate. After the unloading component 3241 holds the cold plate, the movement of the push plate 322 can move the cold plate, allowing it to move out of the base frame 1 and facilitating its entry into the next production stage.

[0059] The implementation principle of a multi-size fixing assembly for a general-purpose automotive battery cold plate in Embodiment 2 of this application is as follows:

[0060] During the process of placing the cold plate into the bottom frame 1, the cold plate first comes into contact with the unloading part 3241 and gradually compresses the elastic part 3244.

[0061] After the cold plate is placed on the base frame 1, the detection element 27 detects the tilt angle of the cold plate and controls the output ends of the two clamping drive elements 21 to move a specified distance respectively, so that the tilt angle of the connecting seat 22 is adapted to the tilt angle of the cold plate. Then, the first roller 23 moves to abut against the side end of the cold plate. At this time, the second roller 24 is located on the underside of the cold plate.

[0062] When the first rollers 23 on both sides of the cold plate abut against the cold plate, the cold plate is clamped. At this time, the lifting drive 25 drives the first connecting plate 221 to rise until the second roller 24 abuts against the bottom of the cold plate, and lifts the cold plate until it is no longer in contact with the base frame 1. After the cold plate is lifted a specified distance and is no longer in contact with the unloading part 3241, the clamping drive 21 moves a specified distance to adjust the position of the cold plate.

[0063] After the cold plate is positioned, the drive component 3231 drives the push plate 322 to move. The push plate 322 pushes the cold plate to abut against the clamping block 31, thereby limiting the cold plate around its perimeter. Then, the lifting drive component 25 drives the first connecting plate 221 to descend, placing the cold plate on the base frame 1. After the cold plate is placed on the base frame, the painting process is carried out.

[0064] After the cold plate is coated, the lifting drive 25 drives the first connecting plate 221 to move a specified distance, raising the cold plate to a state where it is not in contact with the base frame 1, and keeping the unloading part 3241 in contact with the bottom of the cold plate. At this time, the unloading part 3241 works to hold the bottom of the cold plate, and at the same time, it pushes the drive 3231 to drive the push plate 322 to move. Driven by the unloading part 3241, the cold plate moves out of the range of the base frame 1 with the push plate 322, thus facilitating the base frame 1 to enter the next production stage.

[0065] Embodiment 2 of this application utilizes the cooperation of the first clamping device 2 and the second clamping device 3 to fix cold-rolled steel sheets of different specifications during the spraying process, thereby improving the automation level of the cold-rolled steel sheet production process and reducing production costs. Simultaneously, it reduces the possibility of wear during the fixing process, improving the production quality of the cold-rolled steel sheets.

[0066] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
