The integrated circuit board is mainly composed of silica gel, so it is generally green. The circuit board is the basis of electronic components. With the rapid development of electronic products, the market demand for circuit boards is increasing, and at the same time, the production quality requirements for circuit boards are also getting higher and higher. During the processing of circuit boards, sometimes the circuit boards need to be cleaned, and after cleaning, they need to be dried before entering the next process.

[0003] In the prior art, there is a circuit board drying device for continuous electroplating equipment with the patent publication number CN215063483U. When the above patent is used, through the mutual cooperation between a box body, a hot air box, a blower, heating wires, a motor, a transmission mechanism, etc., the blower can convey the heated air into the spray pipe to dry the circuit board, and the motor drives the spray pipe to move left and right reciprocally through a reciprocating lead screw, which can effectively improve its use efficiency. However, there are still the following deficiencies in actual use: Starting from reality, when the device is in use, the spray pipes arranged on the rectangular blocks symmetrically arranged up and down blow dry the circuit board from above and below at the same time, which may cause the local temperature to be too high and damage the circuit board. Moreover, when the device transports circuit boards with different thicknesses, there is a lack of a limiting device, resulting in easy tilting during transportation and affecting the drying effect.

[0024] The drying mechanism 4 is composed of a transmission shaft 401, a gear 402, a rack 403, a limit block 404, a connecting plate 405, a moving plate 406, a heating pipe 407, a fan 408 and a jet pipe 409. The transmission shaft 401 is symmetrically and rotatably connected to the front and rear inner surfaces of the protective cover 3. The transmission shaft 401 is connected to the output end of the second motor. The gear 402 is fixedly connected to the outside of the transmission shaft 401. The racks 403 are symmetrically arranged on the upper and lower sides of the gear 402, and the racks 403 are meshed with the gear 402. The connecting plate 405 is fixedly connected to the side of the rack 403 away from the gear 402. The moving plate 406 is fixedly connected to the lower part of the connecting plate 405.

[0025] Further, as shown in Figure 1 , Figure 2 and Figure 4 it is worth specifically stating that the limit blocks 404 are symmetrically and fixedly connected to the inside of the protective cover 3, and the racks 403 are slidably connected to the inside of the limit blocks 404.

[0026] Further, as shown in Figure 1 , Figure 2 and Figure 4 it is worth specifically stating that the heating pipes 407 are uniformly fixedly connected to the inside of the moving plate 406. The fans 408 are symmetrically arranged above the heating pipes 407, and the fans 408 are fixedly connected to the moving plate 406. The jet pipes 409 are uniformly fixedly connected to the bottom surface of the moving plate 406;

[0027] By starting the heating pipes 407, the heat of the heating pipes 407 is ejected through the fans 408 through the jet pipes 409 and sprayed onto the upper and lower surfaces of the circuit board for drying at the same time.

[0028] Further, as shown in Figure 1 , Figure 2 and Figure 4 it is worth specifically stating that a second motor is fixedly connected to the middle of the front surface of the protective cover 3, and the output end of the second motor is connected to the front end of the transmission shaft 401 on the front surface.

[0029] According to the above working process, it can be seen that: by setting the drying mechanism 4, the transmission shaft 401 can drive the gear 402 to rotate, and then drive the two moving plates 406 to move through the upper and lower racks 403, so as to blow-dry the upper and lower surfaces of the circuit board in a staggered manner, avoiding blowing-drying the upper and lower surfaces of the same position of the circuit board at the same time, causing local overheating and damaging the circuit board, and improving the safety and efficiency of drying.

[0030] Further, as shown in Figure 1 , Figure 2 and Figure 3As shown, it is worth specifically explaining that the limiting mechanism 2 is composed of a support plate 201, a lead screw 202, a slide bar 203, a moving block 204, a first connecting shaft 205, an upper roller body 206, a first motor 207, a second connecting shaft 208, and a lower roller body 209. The support plate 201 is symmetrically and fixedly connected above the bottom plate 1. The lead screw 202 is threadedly connected to the upper part inside the front support plate 201. The slide bar 203 is fixedly connected to the inside of the rear support plate 201. There are two moving blocks 204, which are symmetrically arranged front and rear. The front moving block 204 is threadedly connected to the outside of the lead screw 202, and the rear moving block 204 is slidably connected to the outside of the slide bar 203.

[0031] Further, as shown in Figure 1 , Figure 2 and Figure 3 it is worth specifically explaining that the first connecting shaft 205 is rotatably connected between the two moving blocks 204, and the upper roller body 206 is fixedly connected to the outside of the first connecting shaft 205.

[0032] Further, as shown in Figure 1 , Figure 2 and Figure 3 it is worth specifically explaining that the first motor 207 is fixedly connected to the front of the support plate 201. The second connecting shaft 208 is connected to the output end of the first motor 207, and the second connecting shaft 208 is rotatably connected to the support plate 201. The lower roller body 209 is fixedly connected to the outside of the second connecting shaft 208;

[0034] This solution has the following working process: During use, place the circuit board above the lower roller 209, and then manually rotate the lead screw 202 to drive the moving block 204 to rotate. Since the rear moving block 204 is slidably connected to the outside of the slide bar 203, it drives the first connecting shaft 205 to move downward until the upper roller 206 moves downward to restrict the circuit board. Then, drive the first motor 207 to drive the second connecting shaft 208 to rotate. Through the rotation of the lower roller 209, the circuit board is driven into the interior of the protective cover 3. Through the internally rotatably arranged conveying wheels 5, the conveying of the circuit board can be limited to ensure the stability of the conveying inside the protective cover 3. When it is conveyed to the interior of the protective cover 3, start the second motor to drive the front drive shaft 401 to rotate. Through the gear 402, the upper and lower racks 403 are driven to move. Through the connecting plate 405, the moving plate 406 is driven to move, so as to drive the two moving plates 406 to move towards each other. At the same time, start the heating tube 407, and the heat of the heating tube 407 is sprayed out through the air jet pipe 409 by the fan 408 and sprayed onto the upper and lower surfaces of the circuit board for drying at the same time, thereby improving the drying efficiency and avoiding damage to the circuit board caused by the high temperature of drying the upper and lower surfaces of the same position at the same time.

[0035] In summary: Through the provided drying mechanism 4, the drive shaft 401 can be driven to rotate the gear 402, and then the two moving plates 406 can be driven to move through the upper and lower racks 403 arranged up and down, so as to blow-dry the upper and lower surfaces of the circuit board in a staggered manner, avoiding blowing and drying the upper and lower surfaces of the same position of the circuit board at the same time, resulting in local overheating and damage to the circuit board, and improving the safety and efficiency of drying; through the provided limiting mechanism 2, circuit boards of different thicknesses can be limited and dried, improving the applicable range of the device, and at the same time preventing the circuit board from shifting or deforming inside the protective cover 3, and improving the drying effect.
