DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Reference Figure 1-Figure 5 A plasma cleaning machine clamping mechanism includes a body 1, two groups of plasma emitters 2 are installed in the body 1 (the plasma emitters 2 are prior art and are not described in detail here), a U-shaped support seat 3 is fixedly installed in the body 1, a U-shaped moving seat 4 is slidably installed on the support seat 3 through a moving assembly, the moving assembly is used to drive the moving seat 4 to reciprocate, the moving assembly includes a reciprocating screw rod 9 rotatably installed on the support seat 3 and a driving motor 10 fixedly installed on the side of the support seat 3, the output shaft of the driving motor 10 is fixedly connected to the reciprocating screw rod 9, a threaded hole is opened on the moving seat 4, and the moving seat 4 is threadedly sleeved on the reciprocating screw rod 9.

[0025] By starting the driving motor 10, the reciprocating screw 9 is driven to rotate on the supporting seat 3. Since the moving seat 4 is threadedly sleeved on the reciprocating screw 9, the moving seat 4 is driven to reciprocate on the supporting seat 3. The moving seat 4 drives the main board to be cleaned to move directly under the two groups of plasma emitters 2 to achieve cleaning.

[0026] A rotating hole is opened on the moving seat 4, and two rotating shafts 5 are provided on the moving seat 4. One of the rotating shafts 5 is rotatably installed on the moving seat 4, and the other rotating shaft 5 is inserted in the rotating hole, and a pull rod 6 is fixedly installed at one end. A clamping block 7 is fixedly installed at one end of the two rotating shafts 5, and a telescopic spring 8 is sleeved on one of the rotating shafts 5, and the telescopic spring 8 is located between the clamping block 7 and the moving seat 4.

[0027] When placing the main board on the movable seat 4, pull the pull rod 6 to drive one of the rotating shafts 5 to move in the rotating hole. At this time, the telescopic spring 8 is compressed, and the clamping block 7 is driven to move through the rotating shaft 5, so that the distance between the two clamping blocks 7 is reduced. Then the main board is placed between the two clamping blocks 7, and the pull rod 6 is released. Under the action of the elastic force of the telescopic spring 8, the two clamping blocks 7 approach each other and clamp the main board between the two clamping blocks 7. Therefore, when the movable seat 4 drives the main board to move, the position of the main board can be prevented from shifting during the cleaning process, ensuring that all parts of the surface of the main board can be fully cleaned, thereby improving the cleaning effect of the device.

[0028] The support seat 3 is symmetrically fixed with limit rails 11, and both limit rails 11 are in sliding contact with the moving seat 4. When the moving seat 4 moves horizontally, the limit rails 11 can limit the moving seat 4 from rotating during movement.

[0029] Support rods 12 are fixedly installed horizontally and symmetrically on both side surfaces of the support seat 3. Every two support rods 12 are respectively in the same vertical plane with the two clamping blocks 7. The support rods 12 intermittently slide in contact with the clamping blocks 7. A transmission assembly for driving the rotating shaft 5 to rotate is provided on the support seat 3. The transmission assembly includes a rotating wheel 13 fixedly sleeved on one of the rotating shafts 5, a mounting block 14 fixedly installed on the support seat 3, a spring rod 15 symmetrically fixedly installed on the top of the mounting block 14 and a resistance block 16 fixedly installed at one end of the two spring rods 15. The longitudinal section of the resistance block 16 is an isosceles trapezoid. The resistance block 16 is located in the middle of the support seat 3 and is in the same vertical plane with the rotating wheel 13. The length of the upper surface of the resistance block 16 is equal to half the circumference of the rotating wheel 13.

[0030] When the moving seat 4 moves to the bottom of one of the plasma emitters 2, the clamping block 7 slides in contact with the support rod 12. Under the action of the support rod 12, the clamping block 7 will not rotate. When the moving seat 4 is about to move to the middle of the two plasma emitters 2, the clamping block 7 will separate from the support rod 12. At this time, the resistance block 16 will just contact the rotating wheel 13. Under the action of resistance, the rotating wheel 13 will be driven to rotate, thereby driving the clamping block 7 to rotate through the rotating shaft 5. Since the upper surface length of the resistance block 16 is equal to the general length of the circumference of the rotating wheel 13, Therefore, when the resistance block 16 is separated from the rotating wheel 13, the rotating shaft 5 just rotates half a circle, just driving the main board to flip one side, and when the resistance block 16 is separated from the rotating wheel 13, the clamping block 7 just contacts the other support rod 12 horizontally. Under the action of the elastic force of the spring rod 15, the rotating wheel 13 is ensured to be in tight contact with the resistance block 16. The moving seat 4 drives the main board to move to the bottom of another plasma emitter 2 to achieve cleaning of the other side. There is no need to manually flip during the cleaning process, the operation is simple, and the cleaning effect of the device is further improved.

[0031] An anti-skid pad is fixedly installed on the surface of the rotating wheel 13. The anti-skid pad is made of rubber material and can increase the friction between the rotating wheel 13 and the resistance block 16 to prevent relative sliding between the two.

[0032] In the utility model, when the mainboard is placed on the movable seat 4, the pull rod 6 is pulled to drive one of the rotating shafts 5 to move in the rotating hole. At this time, the telescopic spring 8 is compressed, and the clamping block 7 is driven to move through the rotating shaft 5. Then the mainboard is placed between the two clamping blocks 7, and the pull rod 6 is released. Under the action of the elastic force of the telescopic spring 8, the two clamping blocks 7 are close to each other, and the mainboard is clamped between the two clamping blocks 7. Therefore, when the movable seat 4 drives the mainboard to move, the position of the mainboard can be prevented from shifting during the cleaning process, ensuring that all parts of the surface of the mainboard can be fully cleaned, thereby improving the cleaning effect of the device.

[0033] In general, with respect to the technical problem that when cleaning the mainboard, due to the lack of clamping and fixing of the mainboard, the position of the mainboard may be shifted during the cleaning process, resulting in that part of the mainboard cannot be cleaned and the cleaning effect is poor; a technical solution is adopted: through the cooperation of the movable seat 4, the rotating shaft 5, the pull rod 6, the telescopic spring 8 and the clamping block 7, the mainboard during the cleaning process can be clamped; because the implementation process of the technical solution is: when the mainboard is placed on the movable seat 4, the pull rod 6 is pulled to drive one of the rotating shafts 5 to move in the rotating hole, at this time the telescopic spring 8 is compressed, and the clamping block 7 is driven to move through the rotating shaft 5, and then the mainboard is placed between the two clamping blocks 7, the pull rod 6 is released, and under the action of the elastic force of the telescopic spring 8, the two clamping blocks 7 are close to each other, and the mainboard is clamped between the two clamping blocks 7; so the technical problem can be solved inevitably, and the technical effect achieved is: when the movable seat 4 drives the mainboard to move, the position of the mainboard can be prevented from shifting during the cleaning process, ensuring that all parts of the mainboard surface can be fully cleaned, and improving the cleaning effect of the device.

[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
