Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0033] To address the problem of uneven heat distribution in existing technologies, which hinders effective drying of circuit boards, the following solution is disclosed. Please refer to [link / reference]. Figures 1-7 This utility model provides a technical solution: an antistatic treatment device for circuit board surface, including a device body 1 and a filter frame 12 disposed inside the device body 1. The device body 1 is provided with a lifting mechanism, and the bottom of the lifting mechanism is inside the filter frame 12. The bottom of the device body 1 is provided with a cavity. The rear end of the device body 1 is connected to a resistance wire heating box 25, and the front end of the resistance wire heating box 25 is connected to a drying mechanism.

[0034] The device body 1 is equipped with a drive motor 2 at the top, and the bottom of the drive motor 2 is connected to the lifting mechanism. The rear end of the device body 1 is connected to the drying mechanism. The drive motor 2 can drive the lifting mechanism or the drying mechanism to operate.

[0035] The drive motor 2 is connected to a first sprocket 3 at its bottom, and a chain 4 is engaged on the outer side of the first sprocket 3. A second sprocket 5 is engaged at the rear end of the chain 4. Both the first sprocket 3 and the second sprocket 5 are provided with ratchet assemblies at their bottoms.

[0036] The second sprocket 5 is rotatably connected to the top of the device body 1 via a bearing seat, and the ratchet assembly includes a first ratchet 6, the bottom of the first ratchet 6 is engaged with a second ratchet 7, and the bottom of the second ratchet 7 is connected to a spring shaft 8. The ratchet assembly at the bottom of the first sprocket 3 and the ratchet assembly at the bottom of the second sprocket 5 face opposite directions.

[0037] The bottom of the first sprocket 3 is connected to the lifting mechanism via a ratchet assembly. The lifting mechanism includes a reciprocating screw 9, and a screw sleeve 10 is provided on the outside of the reciprocating screw 9. A fixing frame 11 is connected to the bottom of the screw sleeve 10, and the bottom of the fixing frame 11 is fixedly connected to the filter frame 12.

[0038] The main body 1 of the device is provided with an inclined plate 15 in the middle, and the top of the inclined plate 15 is rotatably connected to the reciprocating lead screw 9. The top of the inclined plate 15 is provided with a sliding rod 14, which is slidably connected to the fixed frame 11.

[0039] The top of the sliding rod 14 is fixedly connected to the main body 1 of the device, and the bottom of the second sprocket 5 is connected to the drying mechanism through a ratchet assembly. The drying mechanism includes a first bevel gear 16, the right end of which meshes with a second bevel gear 17, and the right end of the second bevel gear 17 is connected to a drive shaft 18. The outside of the drive shaft 18 is connected to a third bevel gear 19, the front end of the third bevel gear 19 meshes with a fourth bevel gear 20, and the front end of the fourth bevel gear 20 is connected to a fan blade 21. The fan blade 21 is located at the front of the resistance wire heating box 25, and the fan blade 21 can transfer the hot air inside the resistance wire heating box 25 to the inside of the main body 1 of the device.

[0040] A water pump 23 is connected to the right end of the main body 1 of the device, and a liquid storage tank 22 is connected to the right end of the water pump 23. A drain port 24 is connected to the left end of the main body 1 of the device, and a clamp 13 is provided inside the filter frame 12.

[0041] Working principle: When using the antistatic treatment device for circuit board surface, first connect the device power supply and the power grid. Then place the circuit board inside the filter frame 12. Then rotate the drive motor 2 in the forward direction, which drives the lifting mechanism to lift the filter frame 12 to the bottom of the device body 1 to be immersed in the antistatic liquid. After immersion, the lifting mechanism is restarted to lift the filter frame 12. Then, the drive motor 2 rotates in the reverse direction, which drives the drying mechanism to transfer the hot air inside the resistance wire heating box 25 to the device body 1, so that the hot air dries the surface of the circuit board inside the filter frame 12.

[0042] When the drive motor 2 rotates in the forward direction, the ratchet group at the bottom of the first sprocket 3 will engage, causing the first ratchet 6 to engage with the second ratchet 7. This causes the second ratchet 7 to drive the reciprocating screw 9 to rotate via the spring shaft 8. Since the ratchet group at the bottom of the second sprocket 5 faces the opposite direction to the ratchet group at the bottom of the first sprocket 3, the ratchet group at the bottom of the second sprocket 5 will disengage, causing the first ratchet 6 to disengage with the second ratchet 7. The second ratchet 7 will then retract under the drive of the spring shaft 8.

[0043] When the drive motor 2 rotates in the forward direction, the first sprocket 3 drives the lifting mechanism through the ratchet assembly, causing the reciprocating screw 9 to drive the screw sleeve 10 and the fixed frame 11 to rise and fall, thereby causing the fixed frame 11 to drive the filter screen frame 12 to rise and fall. When the drive motor 2 rotates in the reverse direction, the bottom of the second sprocket 5 drives the drying mechanism through the ratchet assembly, causing the first bevel gear 16 to drive the second bevel gear 17 and the drive shaft 18 to rotate, thereby causing the drive shaft 18 to drive the third bevel gear 19 to rotate, thereby causing the third bevel gear 19 to drive the fourth bevel gear 20 and the fan blade 21 to rotate, thereby causing the fan blade 21 to transfer the hot air inside the resistance wire heating box 25 to the inside of the device body 1.

[0044] When the antistatic liquid is being transferred inside the main body 1, the antistatic liquid inside the storage tank 22 can be transferred to the main body 1 by the water pump 23. When the antistatic liquid is being discharged, it can be discharged through the drain port 24 at the left end of the main body 1.

[0045] This completes a series of tasks. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
