[0002] An industrial control board (circuit board) is an electronic board used in industrial automation and control systems. It is usually used to monitor and control production equipment, process control, data acquisition, system integration and other tasks. An industrial control board has high reliability, durability and anti-interference capabilities in industrial environments. There are many components installed on the industrial control board, which has a certain recycling value. After recycling, the electroplated protective layer on the industrial control board needs to be polished.

[0020] The present invention also provides a surface treatment method for industrial control board processing, which is characterized by comprising the above-mentioned surface treatment device for industrial control board processing, and further comprising the following steps:

[0021] S1. First, place the industrial control board on the conveying component, then fix the industrial control board through the fixing component, and then transport the industrial control board to the bottom of the second sandblasting head through the conveying component. The second sandblasting head sprays high-speed cleaning steel sand to perform preliminary grinding and cleaning on the coating on the industrial control board. The fixing component can be adjusted according to the sandblasting cleaning effect of the industrial control board to adjust the angle between the industrial control board and the second sandblasting head to achieve a better sandblasting cleaning effect.

[0022] S2. During the initial grinding, the sandblasting head 2 is driven to rotate at high speed by fixing the grinding assembly. The steel sand ejected from the high-speed rotating sandblasting head 2 will generate inertia in the horizontal direction. When the steel sand contacts the industrial control board, it will not only generate vertical impact force between the industrial control board and the industrial control board, but also generate horizontal impact force under the action of inertia, thereby achieving a better grinding and cleaning effect;

[0023] S3. After the initial grinding is completed, the industrial control board will enter the scanning box along with the conveying component. The scanning box will scan and sense the residual coating on the industrial control board, and then control the mobile grinding component to move, so that the sandblasting head 1 moves to the top of the industrial control board to be polished, and the industrial control board will be finely polished by the sandblasting head 1. The sandblasting head 1 can change the angle according to the position of the coating on the industrial control board, and perform targeted sandblasting and grinding on the coating on the industrial control board. Not only the coating on the surface can be polished, but also the coating at the corners and holes on the industrial control board can be polished, and the polishing is more thorough.

[0024] Compared with the prior art, the present invention has the following advantages:

[0025] 1. When the surface treatment device for industrial control board processing is grinding the surface of the industrial control board, the sandblasting head 2 is set to perform preliminary sandblasting on the industrial control board. Compared with grinding with a grinding strip, the grinding efficiency is higher and the grinding is more uniform. At the same time, the steel sand used for sandblasting can be recycled and reused, and the material loss is low.

[0026] 2. When the surface treatment device for industrial control board processing is grinding the surface of the industrial control board, the motor three is set to drive the sandblasting head two to rotate at a high speed. The steel sand sprayed by the sandblasting head two not only has a high speed in the vertical direction, but also generates high-speed inertia in the horizontal direction. The high-speed inertia in the horizontal direction will improve the grinding efficiency of the industrial control board.

[0027] 3. When the surface treatment device for industrial control board processing is grinding the surface of the industrial control board, a sandblasting head with freely changeable angles and a scanning box are set to perform targeted grinding on the industrial control board after preliminary grinding. Not only the bent parts of the industrial control board can be ground, but also the coating in the holes on the industrial control board can be ground, so that the industrial control board can be ground more thoroughly.

[0028] To sum up, when the present invention is grinding the industrial control board, not only the surface of the industrial control board can be ground, but also the bending parts of the industrial control board and the inside of the holes on the industrial control board can be ground, and there are two grinding methods: preliminary grinding and fine grinding, so that the grinding is more thorough. In addition, the grinding steel sand used in the grinding process can be recycled and reused, and the material loss is low. The use of sandblasting has the advantages of uniform grinding, high grinding efficiency and precise control of surface roughness. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0046] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0047] Example 1: Reference Figure 1-Figure 6 A surface treatment device for industrial control board processing includes multiple legs 1, a shell 5 and a scanning box 8; a conveying part, used to convey the industrial control board to realize automatic loading of the industrial control board, and the conveying part includes a conveying component and a fixing component. The conveying component is used to transport the industrial control board, and the fixing component is used to fix the industrial control board on the conveying component to improve the stability of the industrial control board and prevent the industrial control board from falling.

[0048] The transmission assembly includes a motor 3 fixedly mounted on one of the legs 1, and the multiple legs 1 are divided into two groups. A rotating shaft 2 is installed between the two legs 1 of each group for common rotation. The driving end of the motor 3 is fixedly connected to one of the rotating shafts 2. Two gears 11 are fixedly mounted on the two rotating shafts 2. A chain 1 is jointly sleeved on the two matching gears 11. The chain 1 is composed of multiple chain links (which are existing chain parts and are not elaborated on here). A supporting frame 4 is jointly fixedly mounted on the two matching legs 1. A baffle 10 matching the corresponding chain 1 is fixedly mounted on the two supporting frames 4. The two baffles 10 are fixedly connected to the outer shell 5.

[0049] The driving end of the motor 3 rotates to drive the rotating shaft 2 fixedly connected thereto to rotate, and cooperates with the gear 11 to drive the chain 1 to rotate, thereby achieving the transmission effect; the function of the baffle 10 is to block the ejected steel sand and reduce the range of high-speed steel sand splashing, thereby making the recycling of steel sand more convenient; the function of the support frame 4 is to limit the support leg 1 and improve the stability of the support leg 1. The rotating shaft 2 and the baffle 10 are rotatably connected through a bearing.

[0050] The fixing assembly includes two connecting rods 14 fixedly installed on the same chain link, a connecting plate 13 is fixedly installed on the two matching connecting rods 14, a placement plate 15 is rotatably installed between the connecting plates 13 on the two chains, the placement plate 15 is fixed to the two connecting plates 13 by bolts, a movable splint 16 is slidably installed on the placement plate 15, a spring 19 is fixedly installed between the movable splint 16 and the placement plate 15, and a fixed splint 17 matching the movable splint 16 is fixedly installed on the placement plate 15.

[0051] Place one end of the industrial control board against the side of the movable clamping plate 16, and place the lower surface of the industrial control board on the fixed clamping plate 17. Then, push the movable clamping plate 16 to move through the industrial control board to compress the spring 19. At this time, the distance between the movable clamping plate 16 and the fixed clamping plate 17 gradually increases until the distance between the two is equal to the length or width of the industrial control board. At this time, the industrial control board will fall between the two, and then manually press the industrial control board downward to make the industrial control board close to the placement plate 15 to complete the fixing operation of the industrial control board.

[0052] The angle of the placement plate 15 can be adjusted by bolts. The purpose of adjusting the angle of the placement plate 15 is to change the non-horizontal state of the surface of the industrial control board placed on the placement plate 15, so that the contact between the sprayed steel sand and the industrial control board is oblique contact rather than vertical contact, which can not only improve the grinding efficiency, but also change the roughness of the surface of the industrial control board (vertical sandblasting is used at the beginning, the impact force is large, and the initial coating cleaning speed is fast. Batch grinding is adopted, and the first batch is vertically sandblasted. After the vertical sandblasting is completed, the industrial control board is removed, the angle of the placement plate 15 is adjusted, and then the industrial control board is placed again on the placement plate 15 with the adjusted angle for inclined sandblasting).

[0053] The placement plate 15 is provided with a slide groove, and a sliding block matching the slide groove is fixedly installed on the movable splint 16. The spring 19 is located inside the slide groove, and the spring 19 is fixedly connected to the sliding block. The purpose of providing the slide groove and setting the sliding block is to facilitate the movement of the movable splint 16. The purpose of arranging the telescopic baffle 18 on the upper part of the slide groove is to block the slide groove to prevent steel sand from entering the slide groove and causing the slide groove to be blocked. Since the telescopic baffle 18 can only block the slide groove on one side of the movable splint 16, and the other side cannot be blocked by the telescopic baffle 18, but the other side is blocked by the processed industrial control board, the steel sand will not enter the inside of the slide groove.

[0054] A rotating shaft 9 is installed on the two support frames 4 for common rotation. The rotating shaft 9 is located in the middle position of the support frames 4. Two gears 2 12 that match the corresponding chain 1 are fixedly installed on the rotating shaft 9. The purpose of this part design is to support the middle part of the chain 1 and reduce the probability of the chain 1 derailing.

[0055] Embodiment 2: This embodiment is different from the embodiment 1 in that: Figure 1-Figure 3 , Figure 7-Figure 15 The polishing part is divided into a fixed polishing component and a mobile polishing component. The fixed polishing component includes a sandblasting head 21 for preliminary polishing of the industrial control board. The mobile polishing component includes a sandblasting head 20, which is used in conjunction with the scanning box 8 to perform targeted fine polishing on the industrial control board.

[0056] The fixed grinding assembly also includes a motor 3 7 fixedly mounted on the outer shell 5, a storage tank 38 is fixedly mounted on the driving end of the motor 37, the sandblasting head 21 is connected to the storage tank 38, and an annular feeding box 37 is rotatably connected to the storage tank 38, and the annular feeding box 37 is connected to an external feeding device.

[0057] The driving end of motor three 7 rotates to drive the storage tank 38 fixedly connected thereto to rotate, thereby driving the sandblasting head two 21 on the storage tank 38 to rotate, so that the steel sand sprayed by the sandblasting head two 21 produces horizontal inertia, thereby generating horizontal impact force on the industrial control board, which is beneficial to improving the grinding efficiency. The rotating annular feeding box 37 on the storage tank 38 is rotationally connected to the storage tank 38, and the annular feeding box 37 is communicated with the storage tank 38, which does not affect the annular feeding box 37 from replenishing steel sand into the storage tank 38 during the rotating sandblasting process.

[0058] In a further embodiment, the mobile grinding assembly also includes a chain 22 rotatably installed inside the outer shell 5 through two limit bearings 24, the chain 22 is composed of a chain body and two gears 3, a motor 26 is fixedly installed on the outer shell 5, the driving end of the motor 26 is fixedly connected to one of the gears 3, and a shock-absorbing plate 30 is installed inside the outer shell 5 through a sliding mechanism, and the shock-absorbing plate 30 is fixedly connected to the sandblasting head 1 20.

[0059] The driving end of motor 2 6 rotates to drive gear 3 fixedly connected thereto to rotate, thereby driving chain 2 22 to rotate. The rotation of chain 2 22 drives the shock-absorbing plate 30 to move, thereby bringing the sandblasting head 1 20 to the top of the industrial control board to be polished. The process is controlled by scanning the coating polishing condition on the industrial control board through the scanning box 8.

[0060] The sandblasting head 20 includes a nozzle 1 31 fixedly connected to the shock absorbing plate 30, a nozzle 2 32 is rotatably mounted on the nozzle 1 31, a nozzle 3 33 is rotatably mounted on the nozzle 2 32, a nozzle 34 is rotatably mounted on the nozzle 3 33, a motor 36 is fixedly mounted on the nozzle 1 31, the nozzle 2 32 and the nozzle 3 33, a gear disc 1 is fixedly mounted on the driving end of each motor 36, and a gear disc 2 35 meshing with the corresponding gear disc 1 is fixedly mounted on the nozzle 2 32, the nozzle 3 33 and the nozzle 34.

[0061] When the sandblasting head 20 is fine-grinding, the scanning box 8 will scan the position of the coating, and then control the motor 36 to operate through the controller, and the motor 36 will drive the gear disc 1 to rotate, and cooperate with the gear disc 2 35 to drive the corresponding nozzle 2 32, nozzle 3 33 and nozzle 34 to rotate, so that the nozzle 34 can rotate at multiple angles, thereby performing multi-angle and all-round sandblasting and cleaning of the residual coating on the industrial control board, thereby improving the grinding and cleaning efficiency and making the grinding and cleaning more thorough.

[0062] The sliding mechanism includes a slide rail 23 fixedly installed inside the housing 5, two sliders 26 are slidably installed on the slide rail 23, a mounting plate 27 is fixedly installed on the two sliders 26, a moving plate 29 is fixedly installed on the mounting plate 27, a connecting block 28 is slidably installed on the moving plate 29, the connecting block 28 is rotationally connected to the chain 22, and the mounting plate 27 is fixedly connected to the shock-absorbing plate 30 via a connecting bracket.

[0063] A limiting plate 25 that cooperates with the slider 26 is fixedly mounted on the slide rail 23 . The limiting plate 25 is used to limit the slider 26 , prevent the slider 26 from being separated from the slide rail 23 , and ensure the stability of the slider 26 moving on the slide rail 23 .

[0064] The movement of chain 22 will drive the connecting block 28 rotatably connected thereto, and the connecting block 28 will drive the moving plate 29 to move. The connecting block 28 will move with the chain 22. When the connecting block 28 moves with the chain 22 to the turning point of the chain 22, the connecting block 28 will slide on the moving plate 29, and then the connecting block 28 will move back with the chain 22, driving the moving plate 29 to move back, and the moving plate 29 will drive the mounting plate 27 fixedly connected thereto to move, and the mounting plate 27 will drive the slider 26 to slide on the slide rail 23, and the slide rail 23 is located below the chain 22, thereby driving the shock-absorbing plate 30 to move. The function of the shock-absorbing plate 30 is to reduce the vibration amplitude of the sandblasting head 20 during sandblasting, improve the stability of sandblasting, and help improve the sandblasting cleaning effect.

[0065] The specific operation steps of this device are as follows:

[0066] First, place one end of the industrial control board against the side of the movable clamping plate 16, and place the lower surface of the industrial control board on the fixed clamping plate 17. Then, push the movable clamping plate 16 to move through the industrial control board to compress the spring 19. At this time, the distance between the movable clamping plate 16 and the fixed clamping plate 17 gradually increases until the distance between the two is equal to the length or width of the industrial control board. At this time, the industrial control board will fall into the gap between the two. Then, manually press the industrial control board downward to make the industrial control board close to the placement plate 15, and complete the fixing operation of the industrial control board.

[0067] Then the driving end of the motor 1 3 rotates to drive the rotating shaft 2 fixedly connected thereto to rotate, and the gear 1 11 drives the chain 1 to rotate. The rotation of the chain 1 drives the placement plate 15 to move through the connecting plate 13 and the connecting rod 14, thereby transporting the industrial control board to the bottom of the sandblasting head 2 21, and the sandblasting head 21 sprays high-speed cleaning steel sand to perform preliminary rough cleaning of the coating on the industrial control board;

[0068] After the rough cleaning is completed, the industrial control board is removed from the placement board 15, and the angle of the placement board 15 is adjusted to make the placement board 15 tilted by 15 degrees. Then, the industrial control board is placed on the placement board 15 and fixed, and a preliminary sandblasting and grinding operation is performed;

[0069] During the preliminary grinding, the driving end of the motor 37 rotates to drive the storage tank 38 fixedly connected thereto to rotate, thereby driving the sandblasting head 21 on the storage tank 38 to rotate, so that the steel sand sprayed by the sandblasting head 21 produces horizontal inertia, thereby generating a horizontal impact force on the industrial control board, which is beneficial to improving the grinding efficiency. The rotating annular feeding box 37 on the storage tank 38 is rotationally connected to the storage tank 38, and the annular feeding box 37 is connected to the storage tank 38, so that it does not affect the annular feeding box 37 to replenish the steel sand in the storage tank 38 during the rotating sandblasting process;

[0070] After the preliminary grinding is completed, the industrial control board will enter the scanning box 8 along with the conveying component, and the scanning box 8 will be used to scan and sense the residual coating on the industrial control board, and then the motor 26 will be turned on, and the driving end of the motor 26 will rotate to drive the gear 3 fixedly connected thereto to rotate, thereby driving the chain 22 to rotate, and the movement of the chain 22 will drive the connecting block 28 connected thereto to rotate, and the connecting block 28 will drive the moving plate 29 to move, and the connecting block 28 will move with the chain 22. When the connecting block 28 moves with the chain 22 to the turning point of the chain 22, the connecting block 28 will slide on the moving plate 29, and then the connecting block 28 will move back with the chain 22, driving the moving plate 29 to move back, and the moving plate 29 will drive the mounting plate 27 fixedly connected thereto to move, and the mounting plate 27 will drive the slider 26 to slide on the slide rail 23, and the slide rail 2 3 is located below the chain 22, thereby driving the shock absorbing plate 30 to move, and the shock absorbing plate 30 will bring the sandblasting head 20 to the top of the industrial control board to be polished. The control of this process is to scan the polishing situation of the coating on the industrial control board through the scanning box 8, and then control the operation of the motor 3 7 through the controller to change the angle of the sandblasting head 20 to finely polish the industrial control board (angle change: when the sandblasting head 20 is finely polishing, the scanning box 8 will scan the position of the coating, and then control the operation of the motor 36 through the controller, and drive the gear plate 1 to rotate through the motor 36, and cooperate with the gear plate 2 35 to drive the corresponding nozzle 2 32, nozzle 3 33 and nozzle 34 to rotate, so that the nozzle 34 can rotate at multiple angles), so as to perform multi-angle and all-round sandblasting and polishing cleaning on the residual coating on the industrial control board, improve the polishing and cleaning efficiency, and make the polishing and cleaning more thorough.
