The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0050] This embodiment provides a laser coating removal device with high operating efficiency, which can prevent the laser from irradiating the battery pole, improve the protection of the pole, improve product yield, and save costs.

[0051] like Figure 1-Figure 4As shown, the laser coating removal device mainly includes a feeding module 100, a conveying module 200 and a laser module 300. Among them, the conveying module 200 is configured to receive and convey the battery 10 clamped by the feeding module 100. The laser module 300 includes a laser generator 310, a support frame 320 and a shielding component 330. The support frame 320 is set beside the conveying module 200. The laser generator 310 is set on one side of the support frame 320. The support frame 320 is provided with a laser hole 3201. The laser emitted by the laser generator 310 can pass through the laser hole 3201 to irradiate the battery 10. The shielding component 330 is located between the laser generator 310 and the battery 10. One end of the shielding component 330 is connected to the support frame 320, and the other end of the shielding component 330 can abut against the top of the battery 10 and shield the pole 11 of the battery 10.

[0052] Based on the above design, in this embodiment, the laser emitted by the laser generator 310 in the laser module 300 can remove the bad coating on the surface of the battery 10, which can not only improve the work efficiency and avoid wear and tear on the battery 10; it can also avoid the problem of chemical solvents corroding the battery 10, extend the service life of the battery 10, and save costs. The shielding component 330 in this embodiment is arranged between the laser generator 310 and the battery 10. At the same time, the shielding component 330 is located on the optical path of the laser. When the transmission module 200 transmits the battery 10 to the laser module 300, the laser generator 310 in the laser module 300 starts and emits laser. The laser passes through the laser hole 3201 on the support frame 320 and irradiates the battery 10 to remove the bad coating on the battery 10. At the same time, the shielding component 330 can shield the laser to prevent the laser from irradiating the pole 11 of the battery 10, thereby protecting the pole 11, avoiding thermal damage, thermal stress cracks and other adverse phenomena on the pole 11, improving the product yield of the battery 10 and saving costs.

[0053] like Figure 1-Figure 4 As shown, in this embodiment, the shielding assembly 330 includes an elastic member 3301 and a cam 3302, one end of the elastic member 3301 is connected to the cam 3302, and the other end of the elastic member 3301 is connected to the top of the support frame 320; the width of the cam 3302 is greater than the width of the laser hole 3201, and the cam 3302 can abut against the top of the battery 10 and shield the pole 11 of the battery 10.

[0054] When the transmission module 200 transmits the battery 10 to the laser module 300, the top of the battery 10 abuts against the cam 3302. At this time, the cam 3302 can stably abut against the top of the battery 10 under the action of the elastic member 3301, avoiding the problem of laser irradiation on the pole 11 caused by a gap between the cam 3302 and the battery 10.

[0055] Furthermore, the shielding assembly 330 in this embodiment also includes a connecting plate 3303, one end of the connecting plate 3303 is connected to the elastic member 3301, and the other end of the connecting plate 3303 is movably connected to the cam 3302 so that the cam 3302 can rotate relative to the connecting plate 3303; the width of the connecting plate 3303 is greater than the width of the laser hole 3201.

[0056] The connection plate 3303 is provided to improve the stability and convenience of the connection between the cam 3302 and the elastic member 3301. At the same time, a rotating shaft is provided on the connection plate 3303, and the cam 3302 is movably connected to the connection plate 3303 through the rotating shaft, so that the cam 3302 can rotate relative to the connection plate 3303. When the battery 10 is transferred to the laser module 300, the cam 3302 is lifted by the battery 10, and the elastic member 3301 contracts. During the transfer of the battery 10, the cam 3302 rotates continuously to reduce hard contact with the top of the battery 10, avoid wear of the battery 10, and protect the battery 10. The laser is shielded by the connection plate 3303 and the cam 3302 to prevent the laser from irradiating the pole 11, thereby protecting the pole 11.

[0057] In this embodiment, the width of the cam 3302 and the width of the connecting plate 3303 are both greater than the width of the laser hole 3201 , which can increase the area of ​​laser shielding and further improve the protection of the pole 11 .

[0058] It should be noted that the width of the cam 3302 in this embodiment is Figure 4 The distance between M and the width of the connecting plate 3303 is Figure 4 The distance N, the width of the laser hole 3201 is Figure 4 In other words, the width of the cam 3302 , the width of the connecting plate 3303 , and the width of the laser hole 3201 are all the size distances along the conveying direction of the battery 10 .

[0059] like Figure 5-Figure 6 As shown, in this embodiment, a fixed fixture 400 is provided on the conveying module 200, and the conveying module 200 is drivingly connected to the fixed fixture 400. A loading position 210 and a unloading position 220 are provided on the conveying module 200, and the fixed fixture 400 can reciprocate between the loading position 210 and the unloading position 220.

[0060] Optionally, the conveying module 200 in this embodiment can be configured as a linear motor, and the fixed fixture 400 is used to receive and place the battery 10 loaded by the loading module 100. The linear motor can transfer the battery 10 between the loading position 210 and the unloading position 220 by forward and reverse rotation. The setting of the fixed fixture 400 can improve the stability and reliability of the placement of the battery 10, and avoid or reduce the risk of the battery 10 shaking or even falling during the conveying process.

[0061] like Figure 5-Figure 6 As shown, further, the fixing fixture 400 in this embodiment includes a first base 410, a first driving component 420 and a clamp 430, the first base 410 is drivingly connected to the transmission module 200, the first driving component 420 is arranged on the first base 410, the clamp 430 is drivingly connected to the first driving component 420, and the first driving component 420 can drive the clamp 430 to clamp the battery 10.

[0062] Optionally, in this embodiment, two clamping plates 430 are provided, and the two clamping plates 430 are arranged opposite to each other. The two clamping plates 430 can be driven by the first driving assembly 420 so that the two clamping plates 430 can clamp or release the battery 10.

[0063] Optionally, the first driving assembly 420 in this embodiment can be configured as a cylinder.

[0064] like Figure 5 As shown, in this embodiment, a sensor 460 is provided on the first base 410, and the sensor 460 is used to detect whether the battery 10 on the first base 410 is placed in place. When the sensor 460 detects that the battery 10 is placed in place, the first driving component 420 drives the clamps 430 on both sides to clamp the battery 10 together.

[0065] It is understandable that the laser coating removal device in this embodiment further includes a controller, which is electrically connected to the sensor 460 and the first drive assembly 420. The sensor 460 can transmit the detected battery 10 position signal to the controller, and the controller can control the first drive assembly 420 to drive the clamping plates 430 on both sides to clamp the battery 10 according to the signal. The controller in this embodiment can be set as a common PLC controller on the market, so the working principle and specific structure of the controller are not described in detail in this embodiment.

[0066] Furthermore, the fixing fixture 400 in this embodiment also includes a rotating assembly 440 and a second base 450 , the second base 450 is drivingly connected to the transmission module 200 , the rotating assembly 440 is disposed on the second base 450 , and the output end of the rotating assembly 440 is connected to the first base 410 .

[0067] The first base 410 can be driven to rotate by the rotating assembly 440. Specifically, when the bad coating on one side of the battery 10 is removed, the rotating assembly 440 can drive the first base 410 to rotate 180 degrees, so that the other side of the battery 10 faces the laser module 300, and then the conveying module 200 rotates in the opposite direction to drive the battery 10 to pass through the laser module 300 again, thereby removing the bad coating on the other side of the battery 10. After the bad coating on both sides of the battery 10 is removed, the conveying module 200 finally transports the battery 10 to the unloading position 220.

[0068] Optionally, the loading module 100 at the loading position 210 and the unloading module 500 at the unloading position 220 in this embodiment have the same structure, which can reduce the cost of the laser coating removal device and facilitate subsequent maintenance and repair.

[0069] like Figure 1-Figure 2 , Figure 7 As shown, in this embodiment, the feeding module 100 includes a second driving assembly 110, a cam follower 120 and at least two clamping jaws 130; the driving end of the second driving assembly 110 is drivingly connected to the cam follower 120, and at least two slide grooves 1201 are provided on the cam follower 120, and the slide grooves 1201 are arranged one by one with the clamping jaws 130, and the clamping jaws 130 are slidably connected with the slide grooves 1201, so that the clamping jaws 130 can clamp or release the battery 10. Exemplarily, the clamping jaws 130 and the slide grooves 1201 in this embodiment can be set to two.

[0070] When the battery 10 needs to be clamped, the second driving assembly 110 drives the cam follower 120 to descend, and at this time, the clamping jaws 130 in the two slide slots 1201 can move upward along the track of the slide slots 1201, thereby clamping the battery 10. When the battery 10 needs to be released, the second driving assembly 110 drives the cam follower 120 to move upward, and at this time, the clamping jaws 130 in the two slide slots 1201 can move downward along the track of the slide slots 1201, increasing the distance between the two clamping jaws 130, thereby releasing the battery 10.

[0071] Optionally, the two slide grooves 1201 in this embodiment are in an "eight-shaped" shape.

[0072] It should be noted that the cam follower 120 in this embodiment is a conventional component in the art, and therefore, the specific structure and working principle of the cam follower 120 will not be described in detail herein.

[0073] Optionally, the second driving assembly 110 in this embodiment can be configured as a cylinder.

[0074] like Figure 7As shown, the loading module 100 in this embodiment further includes a connecting frame 140, on which a first slide rail 1401 and a second slide rail 1402 are provided, a fixed end of the second driving assembly 110 is connected to the connecting frame 140, a cam follower 120 is slidably connected to the first slide rail 1401, and a clamping jaw 130 is slidably connected to the second slide rail 1402. The second driving assembly 110 can drive the cam follower 120 to move up and down on the first slide rail 1401, and then the cam follower 120 drives the clamping jaw 130 to move on the second slide rail 1402, so as to achieve the purpose of clamping or releasing the battery 10 by the clamping jaw 130.

[0075] Furthermore, the loading module 100 in this embodiment also includes a third driving component 150, which is drivingly connected to the connecting frame 140 to drive the connecting frame 140 to move up and down, so that the clamping jaws 130 can be close to or away from the battery 10 to facilitate the taking and placing of the battery 10.

[0076] Optionally, the third driving assembly 150 in this embodiment can be configured as a motor or a cylinder.

[0077] Since the structure of the loading module 100 in this embodiment is the same as that of the unloading module 500 , the specific structure of the unloading module 500 will not be described in detail herein.

[0078] This embodiment also provides a battery processing device, which includes the above-mentioned laser coating removal device. When processing and producing the battery 10, the battery processing device can prevent the laser from irradiating the pole 11 of the battery 10, thereby improving the protection of the pole 11, improving the product yield, and saving costs.
