Description

Technical Field

[0001] This invention relates to the field of sandblasting vehicle cleaning technology, and more specifically, to a sandblasting vehicle cleaning device. Background Technology

[0002] Sandblasting machines use compressed air as power, and the sand-air mixture forms a high-speed jet that propels the abrasive material along the conveying pipe at high speed onto the surface of the workpiece to be treated. This causes the adhering substances on the surface of the workpiece to peel off or changes the mechanical properties of the outer surface. After the product has been sandblasted, the carrier used to support it needs to be cleaned in time for reuse. Existing cleaning equipment requires a robotic arm to move and transport the carrier carrying the product after each cleaning operation. This method occupies a large area during operation, and the use of a robotic arm increases the handling and transportation time, reducing the cleaning efficiency of the device.

[0028] Example

[0029] Please see Figure 1-8 The present invention provides the following technical solutions:

[0030] A sandblasting carrier cleaning device includes a base 1, a conveying assembly 2 and a return assembly 3 mounted on the top of the base 1, the return assembly 3 being located on one side of the conveying assembly 2, a bearing assembly 4 slidably connected to the top of the return assembly 3, a protective assembly 5 mounted on the top of the base 1, the return assembly 3 passing through the interior of the protective assembly 5, a cleaning assembly 6 mounted inside the protective assembly 5, the cleaning assembly 6 being located directly above the return assembly 3, two blocking assemblies 7 and two positioning platforms 8 mounted on the top of the base 1, the blocking assemblies 7 and positioning platforms 8 on the same side forming a group, both groups of blocking assemblies 7 and positioning platforms 8 being installed below the conveying assembly 2, according to... Figure 1As shown, the positioning platform 8 at the front end of the top of the base 1 is the post-sandblasting positioning platform 8, used to support the product after sandblasting. The positioning platform 8 at the rear end of the top of the base 1 is the pre-sandblasting positioning platform 8, used to support the product before sandblasting. Two blocking components 7 respectively limit and block the products on the two positioning platforms 8. A robot arm is connected to the side of the base 1 near the protective component 5. The robot arm is used to place the product on the pre-sandblasting positioning platform 8, convey it through the conveying component 2 and process the product through the sandblasting machine. After processing, it flows back to the post-sandblasting positioning platform 8 through the conveying component 2. The robot arm removes the product from this position. The carrier component supporting the product can be obtained through the conveying component 2. The return component 3 is used to displace the conveying component 2. When the conveying component 2 is displaced into the protective component 5, the cleaning component 6 inside the protective component 5 can clean the carrier component.

[0031] The conveying assembly 2 includes a first conveyor belt 21 and a second conveyor belt 22. Both the first conveyor belt 21 and the second conveyor belt 22 are installed on the top of the base 1. Two sets of blocking assemblies 7 and positioning platforms 8 are respectively installed below the first conveyor belt 21 and the second conveyor belt 22. The first conveyor belt 21 is used to control product return, and the second conveyor belt 22 is used to control product conveying waiting for processing. The corresponding positioning platforms 8 and blocking assemblies 7 can control the conveying of products in different states.

[0032] The return assembly 3 includes a bracket 31, which is mounted on the top of the base 1 and located on one side of the conveying assembly 2. A slide rail 32 is mounted on the top of the bracket 31. The carrying assembly 4 is slidably connected to the top of the slide rail 32. A rodless cylinder 33 is installed inside the slide rail 32 and is connected to the carrying assembly 4. The bracket 31 is used to support the slide rail 32, thereby lifting the slide rail 32 and the carrying assembly 4. The height of the carrying assembly 4 is the same as the height of the conveying assembly 2. The rodless cylinder 33 is used to push the carrying assembly 4 to slide on the slide rail 32, thereby adjusting the position of the carrying assembly 4 on the slide rail 32.

[0033] The carrying assembly 4 includes a slide 41, which is slidably connected to the top of the slide rail 32. The bottom of the slide 41 is connected to the housing of the rodless cylinder 33. A synchronous belt 42 with the same width as the first conveyor belt 21 and the second conveyor belt 22 is installed on the top of the slide 41. A sandblasting carrier 43 is provided on the top of the synchronous belt 42. Clamps 44 are evenly arranged on the top of the sandblasting carrier 43. A buffer 45 is installed on the top of the slide 41 and on the side away from the conveying assembly 2. A photoelectric sensor 46 is installed on the top of the buffer 45. The photoelectric sensor 46 and the synchronous belt 42 are electrically connected by wires. The sandblasting carrier 43 is used to carry the product, and the clamps 44 are used to clamp and fix the product. When the carrying assembly 4 moves as a whole... When the product reaches the end of the second conveyor belt 22, the synchronous belt 42 starts running, thereby conveying the sandblasting carrier 43 to the second conveyor belt 22 for product loading. After the product is processed, the sandblasting carrier 43 and the product are moved to the position of the sandblasting post-positioning platform 8 by the first conveyor belt 21. The bearing assembly 4 is reset to the position of the first conveyor belt 21. After the robot arm removes all the products, the first conveyor belt 21 conveys the sandblasting carrier 43 to the synchronous belt 42. The buffer 45 is used to block the sandblasting carrier 43, and the photoelectric sensor 46 is used to sense the position of the sandblasting carrier 43. If the sandblasting carrier 43 moves into position on the synchronous belt 42, the photoelectric sensor 46 can control the synchronous belt 42 to stop moving.

[0034] The protective assembly 5 includes a protective cover 51, which is mounted on the top of the base 1. A slide rail 32 passes through the interior of the protective cover 51. The bottom of the protective cover 51 extends through the top of the base 1 and connects to a collection chamber 52. The bottom of the collection chamber 52 connects to a discharge pipe 53. The cleaning assembly 6 includes a first support frame 61, which is mounted on the top of the base 1 and located inside the protective cover 51. Two springs 64 are mounted on the inner top wall of the protective cover 51. A nozzle 63 is mounted on the bottom of each spring 64. A connecting pipe 62 connects to the top of the nozzle 63. One end of the connecting pipe 62 extends to the outside of the protective cover 51. The protective cover 51 supports the cleaning assembly 6. The connecting pipe 62 connects to an external air supply device. The fan is not specifically defined here. When the bearing component 4 moves the empty sandblasting carrier 43 into the interior of the protective cover 51, the air supply equipment sprays gas through the connecting pipe 62 and the nozzle 63. Supported by the spring 64, the nozzle 63 is tilted, causing the air sprayed from the nozzle 63 to have an angle. After the air blows onto the surface of the empty sandblasting carrier 43, the impurities remaining on the surface of the sandblasting carrier 43 are blown out. As the sandblasting carrier 43 moves continuously, the air completely cleans the surface of the sandblasting carrier 43. The impurities fall into the collection chamber 52 and are discharged and collected through the discharge pipe 53. When the sandblasting carrier 43 is removed from the protective cover 51, the cleaning is completed. The clean sandblasting carrier 43 moves to the position of the second conveyor belt 22 for reuse.

[0035] Both blocking components 7 include blocking cylinders 71. Both blocking cylinders 71 are mounted on the top of the base 1 and are located below the first conveyor belt 21 and the second conveyor belt 22, respectively. The piston rods of both blocking cylinders 71 are equipped with stop seats 72. The top of the stop seat 72 is hinged with a stop block 73. When the synchronous belt 42 moves the clean sandblasting carrier 43 to the position of the pre-sandblasting positioning platform 8, the piston rod of the blocking cylinder 71 extends and drives the stop seat 72 and the stop block 73 to move upward. The stop block 73 blocks the sandblasting carrier 43, making it convenient for the robot to load the product.

[0036] When the first conveyor belt 21 transports the sandblasting carrier 43 to the position of the sandblasting post positioning platform 8, the corresponding blocking cylinder 71 drives the stop seat 72 and the stop block 73 to block the sandblasting carrier 43, so that the robot can unload the product.

[0037] One end of the stop block 73 is rotatably connected to a wheel 74. An inclined portion 75 is provided at the end of the stop block 73 near the wheel 74. The distance between the top of the stop block 73 and the stop seat 72 is small. When the sandblasting carrier 43 and the stop block 73 come into contact, the wheel 74 on the stop block 73 first contacts the sandblasting carrier 43. The stop block 73 swings under the influence of the thrust of the sandblasting carrier 43. As the stop block 73 continues to swing, the end of the stop block 73 away from the wheel 74 contacts the stop seat 72, causing the stop block 73 to swing to its limit. One side of the sandblasting carrier 43 slides from the position of the wheel 74 to the position of the inclined portion 75. At this time, the sandblasting carrier 43 completes the blocking.

[0038] Both positioning platforms 8 include a second support frame 81, which is mounted on the top of the base 1. The two second support frames 81 are located below the first conveyor belt 21 and the second conveyor belt 22, respectively. The second support frame 81 corresponding to the first conveyor belt 21 is located on the side of the corresponding blocking cylinder 71 closer to the return assembly 3, while the second support frame 81 corresponding to the second conveyor belt 22 is located on the side of the corresponding blocking cylinder 71 away from the return assembly 3. A lifting cylinder 83 is mounted on the top of each of the two second support frames 81, and the piston rod of the lifting cylinder 83 is connected to a base plate 84. Two L-shaped height limiting plates 82 are symmetrically mounted on the top of the second support frames 81, with the tops of the two L-shaped height limiting plates 82 extending to the base plate 8. Above 4, and the top of the L-shaped height limiting plate 82 overlaps with the top of the base plate 84. One end of the first conveyor belt 21 and the second conveyor belt 22 are respectively inserted between the two base plates 84 at the top of the corresponding second support frame 81. When the sandblasting carrier 43 moves to the position above the two positioning platforms 8, the lifting cylinder 83 pushes the base plate 84 and the sandblasting carrier 43 upward. The top surface of the sandblasting carrier 43 contacts the inner wall of the L-shaped height limiting plate 82. At this time, the sandblasting carrier 43 is separated from the conveying assembly 2 and remains stationary, which facilitates the robot to load and unload products. After the products are loaded and unloaded, the lifting cylinder 83 drives the base plate 84 and the sandblasting carrier 43 downward, causing the sandblasting carrier 43 to fall back onto the conveying assembly 2 to continue conveying.

[0039] Specifically, the device is first electrically connected to the control system. The control system controls the operation of the first conveyor belt 21 and the second conveyor belt 22. The operator places the sandblasting carrier 43 at the position of the pre-sandblasting positioning platform 8. The control system then activates the blocking cylinder 71 corresponding to the pre-sandblasting positioning platform 8. The piston rod of the blocking cylinder 71 extends and drives the stop seat 72 and the stop block 73 to move upward. The stop block 73 blocks the sandblasting carrier 43. When the sandblasting carrier 43 and the stop block 73 come into contact, the wheel 74 on the stop block 73 first contacts the sandblasting carrier 43. The stop block 73 swings under the thrust of the sandblasting carrier 43. As the stop block 73 continues to swing, the end of the stop block 73 away from the wheel 74 contacts the stop seat 72, causing the stop block 73 to swing to its limit. One side of the sandblasting carrier 43 slides from the position of the wheel 74 to the position of the inclined part 75. The sandblasting carrier 43 completes the blocking, causing the stop block 73 to remain stationary in the conveying direction of the second conveyor belt 22. At this time, the control system controls the corresponding lifting cylinder 83 to push the base plate 84 and the sandblasting carrier 43 upward. The top surface of the sandblasting carrier 43 contacts the inner wall of the L-shaped height limit plate 82. At this time, the sandblasting carrier 43 disengages from the second conveyor belt 22 and remains stationary. The robot arm performs the product loading operation. After the product loading is completed, the lifting cylinder 83 drives the base plate 84 and the sandblasting carrier 43 downward, causing the sandblasting carrier 43 to fall back onto the second conveyor belt 22. The control system controls the piston rod of the blocking cylinder 71 to retract again, thereby canceling the blocking of the sandblasting carrier 43.

[0040] The second conveyor belt 22 continues to transport the sandblasting carrier 43 and the product to the sandblasting machine for product processing. After the product processing is completed, the sandblasting carrier 43 transports the sandblasted product to the first conveyor belt 21 for return transport. The first conveyor belt 21 transports the sandblasting carrier 43 to the position of the sandblasting positioning platform 8. The control system controls the corresponding blocking cylinder 71 to drive the stop seat 72 and the stop block 73 to block the sandblasting carrier 43. The sandblasting carrier 43 remains stationary in the conveying direction of the first conveyor belt 21. At this time, the control system controls the corresponding lifting cylinder 83 to push the base plate 84 and the sandblasting carrier 43 upward. The sandblasting carrier 43 separates from the first conveyor belt 21 and remains stationary. The robot unloads the product. After the product unloading is completed, the lifting cylinder 83 drives the base plate 84 and the sandblasting carrier 43 downward, causing the sandblasting carrier 43 to fall back onto the first conveyor belt 21. The control system controls the piston rod of the blocking cylinder 71 to retract again, thereby canceling the blockage of the sandblasting carrier 43.

[0041] The first conveyor belt 21 continues to convey, and the sandblasting carrier 43 gradually separates from the first conveyor belt 21. At this time, the synchronous belt 42 gradually takes over the sandblasting carrier 43. As the sandblasting carrier 43 gradually moves onto the synchronous belt 42, the buffer 45 blocks the sandblasting carrier 43. The photoelectric sensor 46 is used to sense the position of the sandblasting carrier 43. If the sandblasting carrier 43 moves into position on the synchronous belt 42, the photoelectric sensor 46 can control the synchronous belt 42 to stop moving.

[0042] The control system controls the rodless cylinder 33 to start, and the rodless cylinder 33 pushes the bearing component 4 to slide on the slide rail 32, thereby adjusting the position of the bearing component 4 on the slide rail 32;

[0043] When the carrier component 4 moves the empty sandblasting carrier 43 into the interior of the protective cover 51, the air supply device sprays gas through the connecting pipe 62 and the nozzle 63. Supported by the spring 64, the nozzle 63 is tilted, causing the air sprayed from the nozzle 63 to have an angle. After the air blows onto the surface of the empty sandblasting carrier 43, the impurities remaining on the surface of the sandblasting carrier 43 are blown out. As the sandblasting carrier 43 moves continuously, the air completely cleans the surface of the sandblasting carrier 43. The impurities fall into the collection bin 52 and are discharged and collected through the discharge pipe 53. When the sandblasting carrier 43 is removed from the protective cover 51, the cleaning is completed. The clean sandblasting carrier 43 moves to the position of the second conveyor belt 22 for reuse.
