Description

Technical Field

[0001] This utility model relates to the field of circuit board coating, and in particular to an automatic feeding device for a circuit board coating machine. Background Technology

[0002] A circuit board coating machine is a device specifically designed to uniformly coat the surface of circuit boards with ink. It is mainly used to protect circuit boards and printed circuit patterns. The working principle of the circuit board coating machine is to uniformly coat the surface of the circuit board with ink through a wet film coater or a bar coater. Some advanced coating machines are also equipped with pressure sensors, which can accurately control the pressure during coating to ensure the uniformity and accuracy of the coating.

[0003] Currently, coating machines use either manual or automated feeding methods. Regardless of the method, the circuit board is pre-moved above the feeding roller, and the coating is achieved by the rotation of the feeding roller. During the feeding process, the circuit board needs to be aligned; otherwise, the coating pattern will be tilted, affecting the coating quality. Existing alignment methods use a rising baffle plate at the circuit board's traveling end, with the side plates pressed towards the center by hydraulic equipment to align the circuit board. However, the inventors found in actual use that after the side pressing plates reset, the rising baffle plate rubs against the circuit board during its descent, causing the circuit board to move and tilt slightly, potentially affecting the subsequent coating quality. Therefore, to address these issues, an automatic feeding device for a circuit board coating machine is proposed. Utility Model Content

[0004] In view of the above-mentioned problems in the prior art, the main purpose of this utility model is to provide an automatic feeding device for a circuit board coating machine. When separating from the circuit board, the device uses a blocking plate to rotate towards the side of the circuit board. This method avoids the circuit board from falling and contacting it, which would cause it to tilt. This ensures stable feeding of the circuit board and guarantees its coating quality.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: an automatic feeding device for a circuit board coating machine, including coating equipment;

[0006] The coating equipment is equipped with automatic feeding rollers for feeding circuit board substrates.

[0007] Hydraulic devices are fixedly connected to both sides of the coating equipment in a symmetrical arrangement. The free end of the hydraulic devices is fixedly connected to a vertically arranged positioning top plate for positioning the circuit board substrate.

[0008] The bottom of the coating equipment is also equipped with a blocking mechanism for blocking the circuit board during the feeding process. Both sides of the blocking mechanism are equipped with transition mechanisms that are fixedly connected to the coating equipment.

[0009] Furthermore, the blocking mechanism includes a mounting frame that is fixedly connected to the coating equipment, a motor that is fixedly connected inside the mounting frame, a rotating shaft that is fixedly connected to the output shaft of the motor, and the other end of the rotating shaft that is rotatably connected to the mounting frame.

[0010] A drive gear is fixedly connected to the outer side of the rotating shaft, a driven gear meshes with the outer side of the drive gear, and a rotating rod is fixedly connected to the inner side of the driven gear. The two ends of the rotating rod are rotatably connected to the mounting frame.

[0011] A disc is fixedly connected to the outside of the rotating rod, and a baffle plate is fixedly connected to the outside of the disc.

[0012] Furthermore, the side of the mounting frame furthest from the transition mechanism is open.

[0013] Furthermore, the baffle plate is curved.

[0014] Currently, coating machines use either manual or automated feeding methods. Regardless of the method, the circuit board is pre-positioned above the feeding roller, and the rotation of the roller facilitates coating. During feeding, the circuit board must be aligned correctly; otherwise, the coating pattern will be tilted, affecting coating quality. Existing alignment methods use a rising baffle plate at the circuit board's traveling end, with side plates pressed towards the center by hydraulic pressure to align the circuit board. However, the inventors discovered in practical use that after the side pressing plates reset, the descending baffle plate rubs against the circuit board. The wiping action can cause the circuit board to move and tilt slightly, potentially affecting the coating quality of subsequent circuit boards. By setting a blocking mechanism below the feeding roller, when blocking the circuit board, the motor drives the rotating shaft to rotate, which in turn drives the driving gear to rotate. The driving gear drives the driven gear to rotate, which in turn drives the inner rotating rod to rotate. The rotating rod drives the outer disc to rotate, thus making the blocking plate vertically positioned to block the circuit board. When separating from the circuit board, the blocking plate rotates towards the side where the circuit board is moving. This method avoids the circuit board from tilting due to contact with it while descending, ensuring stable feeding of the circuit board and guaranteeing its coating quality.

[0015] Furthermore, the transition mechanism includes a horizontal plate that is fixedly connected to the coating equipment. The horizontal plate has a rectangular groove inside, and multiple sets of conveying shafts that are rotatably connected to the horizontal plate are arranged inside the rectangular groove. Conveying rollers are fixedly connected to the outside of each conveying shaft.

[0016] Furthermore, the upper surface of the conveyor roller is 2cm higher than the upper surface of the horizontal plate, and the top of the conveyor roller is on the same horizontal plane as the top of the feeding roller.

[0017] Transition mechanisms are provided on both sides of the blocking mechanism. The conveying roller protrudes upward, and the circuit board can be guided after contacting it, thus achieving the purpose of conveying and transitioning. The power is provided by the rotation of the feeding roller.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] 1. By setting a blocking mechanism below the feeding roller, when blocking the circuit board, the starting motor drives the rotating shaft to rotate, the rotating shaft drives the driving gear to rotate, the driving gear drives the driven gear to rotate, the driven gear drives the inner rotating rod to rotate, and the rotating rod drives the outer disc to rotate, so that the blocking plate is set vertically to block the circuit board. When separating from the circuit board, the blocking plate rotates towards the side of the circuit board. This method avoids the circuit board from falling and contacting it, which would cause it to tilt. This ensures stable feeding of the circuit board and guarantees the quality of its subsequent coating.

[0020] 2. Transition mechanisms are provided on both sides of the blocking mechanism. The conveying roller protrudes upward. After the circuit board comes into contact with it, it can guide the circuit board and serve as a conveying transition. The power is provided by the rotation of the feeding roller.

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments. Example

[0026] An automatic feeding device for a circuit board coating machine, such as Figure 1-3 As shown, it includes coating equipment 1;

[0027] The coating equipment 1 is equipped with an automatic feeding roller 2 for feeding circuit board substrates;

[0028] Hydraulic devices 3 are fixedly connected to both sides of the coating equipment 1 in a symmetrical arrangement. A vertically arranged positioning top plate 4 for positioning the circuit board substrate is fixedly connected to the free end of the hydraulic device 3.

[0029] The bottom of the coating equipment 1 is also equipped with a blocking mechanism 5 for blocking the circuit board during the feeding process. Both sides of the blocking mechanism 5 are provided with transition mechanisms 6 that are fixedly connected to the coating equipment 1.

[0030] The blocking mechanism 5 includes a mounting frame 501 fixedly connected to the coating equipment 1. A motor 502 is fixedly connected inside the mounting frame 501. A rotating shaft 503 is fixedly connected to the output shaft of the motor 502. The other end of the rotating shaft 503 is rotatably connected to the mounting frame 501.

[0031] A drive gear 504 is fixedly connected to the outer side of the rotating shaft 503. A driven gear 505 meshes with the outer side of the drive gear 504. A rotating rod 506 is fixedly connected to the inner side of the driven gear 505. The two ends of the rotating rod 506 are rotatably connected to the mounting frame 501.

[0032] A disc 507 is fixedly connected to the outer side of the rotating rod 506, and a baffle plate 508 is fixedly connected to the outer side of the disc 507.

[0033] The side of the mounting frame 501 away from the transition mechanism 6 is open.

[0034] The baffle plate 508 is curved.

[0035] Currently, coating machines use either manual or automated feeding methods. Regardless of the method, the circuit board is pre-positioned above the feeding roller, and the rotation of the roller facilitates coating. During feeding, the circuit board needs to be aligned correctly; otherwise, the coating pattern will be tilted, affecting coating quality. Existing alignment methods use a rising baffle plate at the circuit board's traveling end, with side plates pressed towards the center by hydraulic equipment to align the circuit board. However, the inventors found in actual use that after the side pressing plates reset, the rising baffle plate rubs against the circuit board during its descent, causing the circuit board to move and tilt slightly. This may affect the coating quality of subsequent circuit boards. By setting a blocking mechanism 5 below the feeding roller 2, when blocking the circuit board, the motor 502 is started to drive the rotating shaft 503 to rotate. The rotating shaft 503 drives the driving gear 504 to rotate, the driving gear 504 drives the driven gear 505 to rotate, the driven gear 505 drives the inner rotating rod 506 to rotate, and the rotating rod 506 drives the outer disc 507 to rotate, so that the blocking plate 508 is set vertically to block the circuit board. When separating from the circuit board, the blocking plate 508 rotates towards the side of the circuit board that is moving. This method avoids the circuit board from falling and contacting it, which would cause it to tilt. This ensures stable feeding of the circuit board and guarantees its coating quality.

[0036] The mounting frame 501 is open on one side, which ensures that the baffle plate 508 can rotate stably.

[0037] The transition mechanism 6 includes a horizontal plate 601 fixedly connected to the coating equipment 1. A rectangular groove is provided inside the horizontal plate 601, and multiple sets of conveying shafts 602 are rotatably connected to the horizontal plate 601 inside the rectangular groove. Conveying rollers 603 are fixedly connected to the outer side of each conveying shaft 602.

[0038] The upper surface of the conveyor roller 603 is 2cm higher than the upper surface of the horizontal plate 601, and the upper surface of the conveyor roller 603 is on the same horizontal plane as the upper surface of the feeding roller 2.

[0039] Transition mechanisms 6 are provided on both sides of the blocking mechanism 5. The conveying roller 603 protrudes upward. After the circuit board comes into contact with it, it can guide the circuit board and serve as a conveying transition. The power is provided by the rotation of the feeding roller 2.

[0040] The upper surface of the conveyor roller 603 is higher than the horizontal plate 601, so it will not come into contact with the horizontal plate 601 when the circuit board is fed, thus ensuring stable conveying of the circuit board.

[0041] Finally, it should be noted that the above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
