[0002] Automatic vehicle body sandblasting is a surface treatment technology that uses a high-speed jet of abrasive to physically impact and rub the vehicle body surface. Its main purpose is to remove stains, oxide layers, paint, and plating from the vehicle body surface, while simultaneously creating different textures and finishes. Sandblasting not only enhances the adhesion of the vehicle body surface but also improves the durability and aesthetics of the coating. The principle of sandblasting is to use a high-speed jet of abrasive to physically impact and rub the vehicle body surface, thereby achieving a cleaning and improvement effect.

[0003] In the existing technology, the automatic sandblasting and cleaning device for vehicle body uses a sandblasting robot to automatically sandblast the vehicle body. However, when the sandblasting robot is automatically sandblasting and cleaning, it cannot sandblast the vehicle body from all directions. Furthermore, when positioning and fixing the vehicle body, it is easy to cause the vehicle body to shake during the sandblasting process, thereby affecting the sandblasting and cleaning effect. Also, it cannot clean the residual sandblasting on the vehicle body during the sandblasting and cleaning process, thus affecting the sandblasting and cleaning effect. Summary of the Invention

A mounting block and a mounting groove cooperate to rotate the lead screw body, causing the mounting block to slide along the mounting groove on the outer wall of the lead screw body. This allows for adjustment of the mounting plate distance by sliding the mounting block. Simultaneously, a first sliding groove and a first slider cooperate, and the activation of a first electric lifting rod raises and lowers the sliding plate and the first connecting plate within the first sliding groove via the first slider. This allows for adjustment of the mounting sleeve height by activating the first electric lifting rod, thereby facilitating adjustment of the lateral and longitudinal distance of the mounting sleeve and improving the sandblasting effect of the sandblasting head.

[0023] This invention proposes an automatic sandblasting and cleaning device and method for vehicle bodies. By starting a second drive motor, the drive shaft and the second gear body are rotated. The second gear body meshes with the first gear body, causing the second gear body to rotate, which in turn drives the first gear body and the rotating rod body to rotate simultaneously. This allows the rotating rod body to rotate, which in turn drives the turntable body to rotate, thereby driving the sandblasting robot base and sandblasting head to rotate in all directions, resulting in a better all-round sandblasting effect on the vehicle body.

[0024] This invention proposes an automatic sandblasting and cleaning device and method for vehicle bodies. A fourth drive motor is activated to rotate the first brush body. The design of the second brush body allows both the first and second brush bodies to rotate and clean the sand from the vehicle body. Simultaneously, a second lead screw body is threadedly connected to a second threaded hole, and a guide rail and guide block cooperate with each other. Activating a third drive motor rotates the second lead screw body, and the guide block and guide rail cause a second connecting plate to slide on the outer wall of the second lead screw body.

[0027] The following is in conjunction with the appendix Figure 1-10 The present invention will be described in further detail below.

[0028] Example 1, please refer to Figure 1-10 As shown, one embodiment of the present invention provides an automatic sandblasting and sand removal device for vehicle bodies, comprising a sandblasting workshop mechanism 1, a lateral movement mechanism 2, a rotation mechanism 3, a sand removal mechanism 4, and a positioning and fixing mechanism 5; the sandblasting workshop mechanism 1 includes a top plate body 101, which is fixedly installed at the top of the sandblasting workshop mechanism 1; sandblasting barrels 102 are installed on the side walls at both ends of the sandblasting workshop mechanism 1; and a sandblasting pump body 103 is installed at the top of the sandblasting barrel 102; the output end of the sandblasting pump body 103 is equipped with a spray nozzle. The sand pipe 104 and the bottom of the sandblasting workshop mechanism 1 are equipped with a track body 105, and a track car 106 is provided at the top of the track body 105. A car body 107 is provided at the top of the track car 106. The side walls at both ends of the sandblasting workshop mechanism 1 are provided with mounting grooves 108, and a mounting plate 109 is provided on one side wall of the mounting groove 108. A sliding plate 1010 is provided on one side wall of the mounting plate 109, and a first connecting plate 1011 is installed at the bottom of one side wall of the sliding plate 1010.

[0029] The sidewall of the mounting plate 109 is provided with a first sliding groove 1093, and a first slider 1094 is provided inside the first sliding groove 1093. The sidewall of the first slider 1094 is fixedly connected to the sidewall of the sliding plate 1010. A first support plate 1091 is installed on the sidewall of the mounting plate 109, and a first electric lifting rod 1092 is installed at the bottom of the first support plate 1091. The bottom of the first electric lifting rod 1092 is fixedly connected to the top of the sliding plate 1010. By activating the first electric lifting rod 1092, the sliding plate 1010 can be adjusted to rise and fall simultaneously.

[0030] The lateral movement mechanism 2 includes a mounting block 201 and a second support plate 203. The mounting block 201 is disposed inside the mounting groove 108, and a first threaded hole 202 is provided inside the mounting block 201. The second support plate 203 is fixedly installed on the side wall of one side of the sandblasting workshop mechanism 1. A first drive motor 204 is installed at the top of the second support plate 203, and a first lead screw body 205 passing through the first threaded hole 202 is installed at the output end of the first drive motor 204 through a coupling. The first lead screw body 205 is threadedly connected to the first threaded hole 202. Through the threaded connection between the first lead screw body 205 and the first threaded hole 202, the rotation of the first lead screw body 205 drives the mounting block 201 to slide on the outer wall of the first lead screw body 205.

[0031] The working principle is as follows: The first drive motor 204 is activated to rotate the first lead screw body 205. The first lead screw body 205 is threadedly connected to the first threaded hole 202. The mounting block 201 cooperates with the mounting groove 108, causing the first lead screw body 205 to rotate and the mounting block 201 to slide through the mounting groove 108 on the outer wall of the first lead screw body 205. This allows the mounting block 201 to slide and adjust the distance of the mounting plate 109. Simultaneously, the first sliding groove 1093 and the first slider 1094 cooperate, and the first electric lifting rod 1092 is activated to raise and lower the sliding plate 1010 and the first connecting plate 1011 through the first slider 1094 within the first sliding groove 1093. This allows the first electric lifting rod 1092 to adjust the height of the mounting sleeve 301, thereby facilitating the adjustment of the lateral and longitudinal distances of the mounting sleeve 301 and improving the sandblasting effect of the sandblasting head 3011.

[0032] Example 2, please refer to Figure 1-10 As shown, the rotating mechanism 3 includes a mounting sleeve 301, which is fixedly mounted on the top of the first connecting plate 1011.

A fourth electric lifting rod 3012 is installed at the top of the sandblasting robot base 308, and one end of the fourth electric lifting rod 3012 is hinged to the bottom end of the second telescopic arm 3010. By hinged to the bottom end of the second telescopic arm 3010, the rotation angle of the second telescopic arm 3010 can be adjusted by activating the fourth electric lifting rod 3012 to raise and lower.

[0034] The output end of the second drive motor 305 is connected to a drive shaft 306 via a coupling. A second gear body 307 is mounted on the top of the drive shaft 306. The second gear body 307 meshes with the first gear body 304. Through the meshing of the second gear body 307 and the first gear body 304, the second drive motor 305 is started to drive the second gear body 307 to rotate and simultaneously drive the first gear body 304 to rotate.

[0035] The working principle is as follows: by starting the second drive motor 305, the drive shaft 306 and the second gear body 307 are driven to rotate. The second gear body 307 meshes with the first gear body 304, causing the second gear body 307 to rotate, which in turn drives the first gear body 304 and the rotating rod body 303 to rotate simultaneously. This allows the rotating rod body 303 to rotate, which in turn drives the turntable body 302 to rotate, thereby driving the sandblasting robot base 308 and the sandblasting head 3011 to rotate in all directions, resulting in a better all-round sandblasting effect on the vehicle body.

[0036] Example 3, please refer to Figure 1-10 As shown, the sand-cleaning mechanism 4 includes a second groove 401 and a third drive motor 4043.

[0037] A second electric lifting rod 409 is installed at the bottom of the first fixed plate 406, and a fixed sleeve 4010 is installed at the bottom of the second electric lifting rod 409. A roller 4011 is provided at the bottom of the fixed sleeve 4010, and a second brush body 4012 is installed at one end of the roller 4011 that is close to each other. A high-pressure spring body 40102 is installed at the top inside the fixed sleeve 4010, and a connecting rod 40101 is installed at the bottom of the high-pressure spring body 40102. The bottom end of the connecting rod 40101 is fixedly connected to the top end of the roller 4011. The height of the fixed sleeve 4010 is adjusted by raising and lowering the second electric lifting rod 409, thereby adjusting the second brush body 4012 to clean the sand from the vehicle body by raising and lowering the fixed sleeve 4010.

[0038] The second connecting plate 404 has a second threaded hole 4041 inside, and the second lead screw body 4042 is threadedly connected inside the second threaded hole 4041.

By starting the third drive motor 4043 to rotate, the second lead screw body 4042 is rotated and the second connecting plate 404 slides on the outer wall of the second lead screw body 4042.

[0039] The working principle is as follows: through the design of the sand-removing mechanism 4, the first brush body 408 is rotated by starting the fourth drive motor 407 to lightly sand the vehicle body, and the third drive motor 4043 is started to adjust the installation box 405 and the first brush body 408 to move laterally at the top of the top plate body 101, so that the first brush body 408 and the second brush body 4012 have a better sand-removing effect on the vehicle body.

[0040] Example 4, please refer to Figure 1-10 As shown, the positioning and fixing mechanism 5 includes a second fixing plate 501, which is fixedly installed on the inner wall of the railcar 106. The top of the second fixing plate 501 is equipped with a mounting bracket 502, and the mounting bracket 502 is hinged to a hinge plate 503.

By hinged to the bottom of the hinge plate 503, the third electric lifting rod 508 is raised and lowered to drive the hinge plate 503 to rotate inside the mounting frame 502.

[0042] The working principle is as follows: the positioning and fixing mechanism 5 is designed, and the third electric lifting rod 508 is activated to lift and lower, thereby driving the hinge plate 503 and the pressing block 507 to rotate and fix the vehicle body. The positioning block 506 and the pressing block 507 are adjusted by rotating the threaded rod 505 to fix the vehicle body, so that the positioning and fixing effect of the positioning and fixing mechanism 5 is better.
