Technical Field

[0001] This invention belongs to the technical field of coating removal devices, and particularly relates to a laser removal device and method for insulating coatings on battery casings. Background Technology

[0002] Some battery casings use paint as the shielding layer; however, when paint is used as the shielding layer, the paint surface that needs to be electroplated needs to be removed using a laser coating removal device to serve as the electrode.

[0003] Laser coating removal devices are only suitable for removing coatings from battery casings with the same regular shape. However, when removing coatings from battery casings of different sizes, it is necessary to change the removal device, which reduces the versatility of laser coating removal devices for removing insulating coatings from battery casings.

A sliding platform is connected to the outer right side of the base plate through a sliding mechanism, and a bearing platform is connected to the top left side of the sliding platform through a rotation and lifting mechanism. The bearing platform is fixedly installed on the top right side of the sliding platform, and an abutment plate is connected to the outer side of the top of the bearing platform through an adjustment mechanism.

[0007] The rotary lifting mechanism includes side support plates symmetrically installed at the top left side of the sliding platform, and side connecting blocks are fixedly installed at the top inner side of each side support plate. The tops of the side connecting blocks are fixedly installed on both sides of the bottom end of the connecting plate. A first motor is installed on the outer left side wall of the left side support plate, and the right output end of the first motor passes through the outer wall of the left side connecting block and is installed in the middle of the outer wall of the left side of the first bevel gear.

A first hydraulic rod is installed in the middle of the top of the second bevel gear, and the top of the first hydraulic rod passes through the middle of the connecting plate and is installed in the middle of the bottom end of the bearing platform. A fixing sleeve is fixedly installed on the outer wall of the upper middle part of the first hydraulic rod, and four sets of side connecting rods are equidistantly connected in a ring at the bottom of the outer outer wall of the fixing sleeve.

[0008] The position between the battery casing of different sizes and the laser removal head can be adjusted to ensure efficient removal of the insulating coating on the battery casing.

[0009] As a preferred embodiment of the above technical solution, the sliding mechanism includes a first threaded sleeve block fixedly installed at the bottom of the sliding platform, and the middle part of the first threaded sleeve block is threadedly connected to the outer wall of the first threaded rod.

The first limiting groove is opened on the outer wall of the top end of the base plate, and the top right end of the first threaded rod is fixedly installed at the middle of the left side of the motor.

[0010] The distance between the battery casing and the laser removal head can be adjusted for different widths to ensure the removal effect of the insulating coating.

[0011] As a preferred embodiment of the above technical solution, multiple sets of rolling beads are equidistantly embedded at both ends of the outer wall of the bottom of the sliding platform, and the bottom ends of the rolling beads roll against the outer wall of the top of the bottom plate.

[0012] The rolling action of the ball bearings enables the sliding platform to move stably at the top of the base plate, improving the stability of the device during use.

[0013] As a preferred embodiment of the above technical solution, the adjustment mechanism includes an L-shaped connecting plate at the top of the abutment plate, and the bottom inner side of the L-shaped connecting plate is fixedly installed in the middle of the outer wall of the second threaded sleeve block. The second threaded sleeve block is threadedly connected to the outer wall of the second threaded rod. The top end of the second threaded rod is movably connected to the middle of the inner wall of the second limiting groove. The bottom end of the second threaded rod is installed on a motor at the bottom inner side of the second limiting groove. The second limiting groove is opened at the upper end of the outer wall of the right side of the support plate. A slider is fixedly installed in the middle of the outer wall of the inner side of the second threaded sleeve block, and the inner sides of the slider are slidably connected to the inner side of the slide rail. The slide rail is opened in the middle of the inner wall of the second limiting groove. The bottom end of the support plate is fixedly installed on the right side of the top of the sliding platform.

[0014] It can limit the battery casing supported at the top of the platform to prevent the battery casing from being flung away by centrifugal force due to rotation.

[0015] As a preferred embodiment of the above technical solution, an anti-slip pad is glued to the top center of the bearing platform, and an abutment pad is glued to the bottom of the abutment plate.

[0016] This can effectively ensure the aesthetic appearance of the battery casing's outer wall.

The outer wall of the first rotating wheel is connected to the second rotating wheel via a transmission belt. A rotating rod is fixedly installed at the middle of the bottom end of the second rotating wheel, and the bottom end of the rotating rod is fixedly installed at the top end of the second motor. The top left end of the second motor is fixedly installed on the outer right side wall of the right side support plate. The first hydraulic rod is installed at the middle of the top end of the first rotating wheel.

[0018] To avoid situations where wear occurs during the meshing connection of the first and second bevel gears, rendering the device unusable.

[0019] As a preferred embodiment of the above technical solution, a second hydraulic rod is fixedly installed on both sides of the bottom end of the bearing platform, and the bottom ends of the second hydraulic rods are all fixedly installed on the top of the first rotating wheel.

[0020] It can perform stable lifting and lowering operations, improving the stability and efficiency of the device during use.

[0023] S2, in conjunction with the lifting action of the first hydraulic rod, enables the lifting platform of the battery casing of the vehicle to be lifted;

[0024] S3. Start the motor. Under the action of the threaded connection between the first threaded rod and the first threaded sleeve, the sliding platform moves horizontally at the top of the base plate to adjust the distance between the battery casing of different widths and the laser removal head.

[0025] S4. Start the motor. Under the action of the threaded connection of the second threaded sleeve and the second threaded rod, and with the limiting sliding action of the slider and the slide rail, the L-shaped connecting plate is driven to move up and down, and the battery shell supported on the top of the bearing platform is limited.

[0026] As a preferred embodiment of the above technical solution, the second motor is started, so that the first hydraulic rod and the side connecting rod at the top of the first rotating wheel are rotated under the transmission action of the first rotating wheel, the transmission belt and the second rotating wheel.

[0037] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0038] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown in the embodiments of the present invention:

[0039] Example 1:

[0040] A laser removal device for insulating coating on battery casing includes a base plate 1, a support base 2, and a laser removal head 3. The support base 2 is installed on the top left side of the base plate 1, and the top of the support base 2 is installed at the middle of the bottom of the laser removal head 3. The outer wall of the right side of the base plate 1 is connected to a sliding platform 7 through a sliding mechanism, and the top left side of the sliding platform 7 is connected to a bearing platform 24 through a rotation lifting mechanism. The bearing platform 24 is fixedly installed on the top right side of the sliding platform 7, and the outer wall of the top of the bearing platform 24 is connected to an abutment plate 27 through an adjustment mechanism.

[0041] The rotary lifting mechanism includes side support plates 9 symmetrically installed on the top left side of the sliding platform 7, and side connecting blocks 10 are fixedly installed on the top inner side of each side support plate 9. The tops of the side connecting blocks 10 are fixedly installed on both sides of the bottom of the connecting plate 14. A first motor 11 is installed on the outer left side wall of the left side support plate 9, and the right output end of the first motor 11 passes through the outer wall of the left side connecting block 10 and is installed in the middle of the outer wall of the left side of the first bevel gear 12. The outer wall of the top of the first bevel gear 12 is meshed with the bottom of the outer wall of the left side of the second bevel gear 13. A first hydraulic rod 20 is installed in the middle of the top of the second bevel gear 13, and the top of the first hydraulic rod 20 passes through the middle of the connecting plate 14 and is installed in the middle of the bottom of the bearing platform 24. A fixing sleeve block 23 is fixedly installed on the outer wall of the upper middle part of the first hydraulic rod 20, and four sets of side connecting rods 21 are equidistantly connected in a ring at the bottom of the outer wall of the fixing sleeve block 23.

[0042] The first motor 11 is started, which drives the first hydraulic rod 20 and the support platform 24 to rotate under the action of the meshing connection of the first bevel gear 12 and the second bevel gear 13. In conjunction with the lifting action of the first hydraulic rod 20, the support platform 24 of the battery housing of the vehicle is lifted and lowered, so that the position between the battery housing of different sizes and the laser removal head 3 can be adjusted to ensure the efficiency of removing the insulating coating of the battery housing.

[0043] like Figure 1 and Figure 3 As shown, the sliding mechanism includes a first threaded sleeve 6 fixedly installed at the bottom of the sliding platform 7, and the middle part of the first threaded sleeve 6 is threadedly connected to the outer wall of the first threaded rod 5. The top left side of the first threaded rod 5 is movably connected to the middle of the inner wall of the first limiting groove 4. The first limiting groove 4 is opened on the top outer wall of the base plate 1, and the top right side of the first threaded rod 5 is fixedly installed in the middle of the left side of the motor.

[0044] The motor is started, and under the action of the threaded connection between the first threaded rod 5 and the first threaded sleeve 6, the sliding platform 7 moves horizontally at the top of the base plate 1, so that the distance between the battery shell of different widths and the laser removal head 3 can be adjusted to ensure the removal effect of the insulating coating.

[0045] like Figure 3 As shown, multiple sets of rolling beads 8 are rolled and embedded at equal distances at the front and rear ends of the bottom outer wall of the sliding platform 7, and the bottom ends of the rolling beads 8 all roll and abut against the top outer wall of the base plate 1.

[0046] The rolling action of the ball bearing 8 enables the sliding platform 7 to move stably at the top of the base plate 1, improving the stability of the device during use.

[0047] like Figure 1 and Figure 4 As shown, the adjustment mechanism includes an L-shaped connecting plate 28 at the top of the abutment plate 27, and the bottom inner side of the L-shaped connecting plate 28 is fixedly installed in the middle of the outer wall of the second threaded sleeve block 29. The second threaded sleeve block 29 is threadedly connected to the outer wall of the second threaded rod 30. The top end of the second threaded rod 30 is movably connected to the middle of the inner wall of the second limiting groove 31. The bottom end of the second threaded rod 30 is installed on the motor at the bottom inner side of the second limiting groove 31. The second limiting groove 31 is opened at the upper end of the right outer wall of the support plate 34. A slider 32 is fixedly installed in the middle of the outer wall of the inner side of the second threaded sleeve block 29, and the inner side of the slider 32 is slidably connected to the inner side of the slide rail 33. The slide rail 33 is opened in the middle of the inner wall of the second limiting groove 31. The bottom end of the support plate 34 is fixedly installed on the right side of the top of the sliding platform 7.

[0048] When the motor is started, the L-shaped connecting plate 28 is moved up and down under the action of the threaded connection of the second threaded sleeve 29 and the second threaded rod 30, and the limiting sliding action of the slider 32 and the slide rail 33. This ensures that the battery casing supported on the top of the bearing platform 24 is limited and prevents the battery casing from being flung away by centrifugal force due to rotation.

[0049] like Figure 1 As shown, an anti-slip pad 25 is glued to the top center of the bearing platform 24, and an abutment pad 26 is glued to the bottom of the abutment plate 27.

[0050] The anti-slip pad 25 and the abutment pad 26 prevent the outer wall of the battery casing from directly contacting the inner outer wall of the support platform 24 and the abutment plate 27, thus avoiding scratches and effectively ensuring the aesthetics of the outer wall of the battery casing.

[0051] Example 2:

[0052] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the rotary lifting mechanism also includes a first rotating wheel 15 through which the top end of the first hydraulic rod 20 passes. The outer wall of the first rotating wheel 15 is connected to the second rotating wheel 17 via a transmission belt 16. A rotating rod 18 is fixedly installed at the middle of the bottom end of the second rotating wheel 17, and the bottom end of the rotating rod 18 is fixedly installed at the top end of the second motor 19. The top left end of the second motor 19 is fixedly installed on the outer right side wall of the right side support plate 9. The first hydraulic rod 20 is installed at the middle of the top end of the first rotating wheel 15.

[0053] Because the teeth of the first bevel gear 12 and the second bevel gear 13 are prone to wear during meshing, if the teeth wear down and the efficiency of the device decreases, the second motor 19 is started. Under the transmission action of the first rotating wheel 15, the transmission belt 16 and the second rotating wheel 17, the first hydraulic rod 20 at the top of the first rotating wheel 15 and the side connecting rod 21 are rotated, so that the battery casing can be rotated and lifted.

[0054] like Figure 1 , Figure 2 and Figure 3 As shown, the bottom of the bearing platform 24 is fixedly installed with second hydraulic rods 22 on both sides, and the bottom ends of the second hydraulic rods 22 are fixedly installed on the top of the first rotating wheel 15.

[0055] Under the action of the second hydraulic rod 22, in conjunction with the first hydraulic rod 20, the bearing platform 24 can carry the battery casing and perform stable lifting operations during removal work, thereby improving the stability and efficiency of the device during use.

[0056] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the laser removal method for the insulating coating on the battery casing includes the following steps:

[0057] S1. Start the first motor 11, so that the first hydraulic rod 20 and the bearing platform 24 will rotate under the action of the meshing connection of the first bevel gear 12 and the second bevel gear 13;

[0058] S2. With the lifting action of the first hydraulic rod 20, the support platform 24 for carrying the battery casing of the vehicle is lifted and lowered.

[0059] S3. Start the motor. Under the action of the threaded connection between the first threaded rod 5 and the first threaded sleeve 6, the sliding platform 7 moves horizontally at the top of the base plate 1 to adjust the distance between the battery shells of different widths and the laser removal head 3.

[0060] S4. Start the motor. Under the action of the threaded connection of the second threaded sleeve 29 and the second threaded rod 30, and with the limiting sliding action of the slider 32 and the slide rail 33, the L-shaped connecting plate 28 is driven to move up and down, and the battery shell supported on the top of the bearing platform 24 is limited.

[0061] S1' starts the second motor 19, which, under the transmission action of the first rotating wheel 15, the transmission belt 16 and the second rotating wheel 17, drives the first hydraulic rod 20 and the side connecting rod 21 at the top of the first rotating wheel 15 to rotate.

[0062] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
