Description

Technical Field

[0001] This utility model relates to the field of PCB board coating technology, specifically to a PCB board coating device for preventing displacement. Background Technology

[0002] PCB boards are the carriers for the electrical connections of electronic components. They achieve circuit connections of components by etching conductive patterns on an insulating substrate. They are widely used in computers, communication equipment, consumer electronics and other fields, and are a core component of electronic devices. To improve the insulation performance, anti-oxidation ability and surface protection effect of PCB boards, their surfaces need to be coated. PCB board coating equipment is an automated processing equipment used to attach protective films, insulating films and other materials to the surface of PCB boards. Its performance directly affects the coating accuracy and product quality.

[0003] In existing PCB board laminating devices, the PCB board is prone to lateral displacement during transport due to factors such as belt vibration and inertia. This can easily lead to insufficient alignment accuracy between the film and the edge of the PCB board during lamination, resulting in lamination misalignment. Furthermore, dust, debris, and other impurities remaining on the PCB board surface can easily get trapped between the PCB board and the film, affecting the lamination adhesion and causing problems such as bubbles and incomplete adhesion. Therefore, a displacement-preventing PCB board laminating device is provided to improve the above-mentioned problems. Utility Model Content

[0004] The purpose of this invention is to provide a PCB board laminating device that prevents displacement. By setting up anti-deviation components and cleaning components, it solves the problem that in existing PCB board laminating devices, the PCB board is prone to left and right deviation during transport due to factors such as belt vibration and inertia. This can easily lead to insufficient alignment accuracy between the film material and the edge of the PCB board during lamination, resulting in lamination misalignment. In addition, dust, debris and other impurities remaining on the PCB board surface can easily get stuck between the PCB board and the film material, affecting the lamination adhesion and causing problems such as bubbles and poor adhesion.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model relates to a PCB board coating equipment for preventing displacement, comprising a belt conveyor, a coating component, an anti-deviation component, and a cleaning component. The anti-deviation component is mounted on the belt conveyor and includes a bidirectional threaded rod with two U-shaped frames threaded onto it. U-shaped plates are mounted on the U-shaped frames. The cleaning component includes a first connecting plate and a second connecting plate. The first connecting plate is mounted on one of the U-shaped frames, and the second connecting plate is mounted on the other U-shaped frame. The first connecting plate and the second connecting plate are slidably engaged. A connecting plate is mounted on the bottom of the first connecting plate, and a cleaning brush is mounted on the bottom of the connecting plate.

[0007] Furthermore, a rectangular groove is provided on the first connecting plate, and a rectangular hole is provided on the rectangular groove. A rectangular plate is installed on the second connecting plate, and the rectangular plate slides in fit with the rectangular groove and the second connecting plate slides in fit with the rectangular hole.

[0008] Furthermore, the anti-deviation component also includes a mounting plate, which is installed on the belt conveyor. The mounting plate has a mounting groove, one end of the bidirectional threaded rod is rotatably engaged with the mounting groove, and the other end of the bidirectional threaded rod is connected to the power output shaft of the drive source, which is installed on the belt conveyor.

[0009] Furthermore, the anti-deviation assembly also includes a guide rod and two support plates. Both support plates are mounted on the belt conveyor, and the two ends of the guide rod are respectively mounted on the two support plates. The U-shaped frame has through holes that slide with the guide rod.

[0010] Furthermore, the coating assembly is installed on the belt conveyor, and the coating assembly is located on one side of the anti-deviation assembly.

[0011] This utility model has the following beneficial effects:

[0012] 1. This utility model, by setting up an anti-deviation component, uses a servo motor to drive a bidirectional threaded rod to rotate, thereby causing the two U-shaped frames and two U-shaped plates to move closer or further apart. The two U-shaped plates limit the PCB board, preventing the PCB board from shifting during transportation and ensuring that the PCB board always moves in the center. This solves the problem in existing PCB board coating devices where the PCB board is easily shifted to the left or right during transportation due to factors such as belt vibration and inertia, which easily leads to insufficient alignment accuracy between the film material and the edge of the PCB board during coating, resulting in coating misalignment.

[0013] 2. This utility model, by setting up a cleaning component, allows the cleaning brush to contact the upper surface of the PCB board when the PCB board is conveyed to the bottom of the cleaning component. As the PCB board moves, the bristles of the cleaning brush sweep away dust, debris and other impurities on the surface of the PCB board. This solves the problem that dust, debris and other impurities remaining on the surface of the existing PCB board are easily trapped between the PCB board and the film material, affecting the adhesion of the film and causing problems such as bubbles and poor adhesion.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 This utility model provides a technical solution: a PCB board coating equipment for preventing displacement, including a belt conveyor 1, a coating component 2, an anti-deviation component 3, and a cleaning component 4. The belt conveyor 1 consists of a conveyor belt, a drive device, transmission components, etc., and is used for continuous conveying of PCB boards. The coating component 2 consists of an unwinding and tension control component, a cutting component, and a drive device, etc., and is used for coating and cutting PCB boards (both the belt conveyor 1 and the coating component 2 are existing technologies and will not be described in detail here).

[0022] The anti-deviation component 3 is installed on the belt conveyor 1. The anti-deviation component 3 includes a bidirectional threaded rod 301, on which two U-shaped frames 302 are threadedly engaged. The threads at both ends of the bidirectional threaded rod 301 are in opposite directions. When rotated, the two U-shaped frames 302 can move closer or further away at the same time, realizing adaptive adjustment for PCB boards of different widths. U-shaped plates 303 are installed on the U-shaped frames 302 by welding. The U-shaped plates 303 on both sides limit the PCB board, directly restricting the left and right deviation of the PCB board during the conveying process, ensuring that the PCB board always moves in the center. The U-shaped opening of the U-shaped plate 303 can accommodate the passage of the cleaning brush 404 without interfering with the movement of the cleaning brush 404.

[0023] The cleaning component 4 includes a first connecting plate 401 and a second connecting plate 402. The first connecting plate 401 is welded to one of the U-shaped frames 302, and the second connecting plate 402 is welded to the other U-shaped frame 302. The first connecting plate 401 and the second connecting plate 402 are slidably engaged. This slidable engagement allows the first connecting plate 401 and the second connecting plate 402 to adjust their spacing synchronously with the U-shaped frame 302, ensuring that the cleaning component 4 and the anti-deviation component 3 do not interfere with each other. A connecting plate 403 is welded to the bottom of the first connecting plate 401, and a cleaning brush 404 is bolted to the bottom of the connecting plate 403. The bristles of the cleaning brush 404 can be made of anti-static PA nylon bristles (soft bristles). The bristles of the cleaning brush 404 directly contact the surface of the PCB board, cleaning the dust and impurities on the surface of the PCB board before it enters the coating component 2, preventing impurities from getting stuck between the PCB board and the coating and affecting the adhesion, thus improving the coating quality.

[0024] The first connecting plate 401 has a rectangular groove 405 and a rectangular hole 406. A rectangular plate 407 is welded onto the second connecting plate 402. The rectangular plate 407 slides in the rectangular groove 405, and the second connecting plate 402 slides in the rectangular hole 406. The rectangular plate 407 slides into the rectangular groove 405, and the second connecting plate 402 slides through the rectangular hole 406, forming a double guide structure to prevent relative shaking or displacement of the first connecting plate 401 and the second connecting plate 402 during adjustment. At the same time, the rectangular plate 407 can prevent the second connecting plate 402 from falling out.

[0025] The anti-deviation component 3 also includes a mounting plate 304, which is installed on the belt conveyor 1 by welding. The mounting plate 304 has a mounting groove 305. One end of the bidirectional threaded rod 301 is rotatably engaged with the mounting groove 305 through a bearing. The other end of the bidirectional threaded rod 301 is connected to the power output shaft of the drive source through a coupling. The drive source is installed on the belt conveyor 1 by bolts. The drive source can be a suitable servo motor.

[0026] The anti-deviation assembly 3 also includes a guide rod 306 and two support plates 307. Both support plates 307 are installed on the belt conveyor 1 by welding. The two ends of the guide rod 306 are respectively installed on the two support plates 307 by welding. The U-shaped frame 302 has a through hole 308, which is slidably engaged with the guide rod 306. The U-shaped frame 302 can prevent the U-shaped frame 302 from rotating or deviating when the bidirectional threaded rod 301 rotates, ensuring that the U-shaped frame 302 moves in a straight line.

[0027] The coating assembly 2 is bolted to the belt conveyor 1 and is located on one side of the anti-deviation assembly 3.

[0028] During operation, the servo motor is first started according to the width of the PCB board to be processed. The power output shaft of the servo motor drives the bidirectional threaded rod 301 to rotate through the coupling. The bidirectional threaded rod 301 drives the two U-shaped frames 302 to move closer to each other. The two U-shaped frames 302 drive the through hole 308 to slide along the guide rod 306, adjusting the distance between the two U-shaped plates 303 to match the width of the PCB board. At the same time, in the cleaning assembly 4, the first connecting plate 401 moves with one of the U-shaped frames 302, and the second connecting plate 402 moves with the other U-shaped frame 302. The rectangular plate 407 slides in the rectangular groove 405, and the second connecting plate 402 slides in the rectangular hole 406 to avoid interference between the cleaning brush 404 and the anti-deviation assembly 3. Then, the PCB board is placed on the conveyor belt of the belt conveyor 1, and the belt conveyor is started. Machine 1: The PCB board moves along the belt towards the laminating assembly 2. When the PCB board passes the anti-deviation assembly 3, the U-shaped plates 303 on both sides limit the edge of the PCB board to prevent the PCB board from shifting left or right due to belt vibration or inertia during the conveying process, ensuring that the PCB board always moves in the center. The PCB board continues to be conveyed to the bottom of the cleaning assembly 4, where the cleaning brush 404 contacts the upper surface of the PCB board. As the PCB board moves, the bristles of the cleaning brush 404 clean the dust, debris and other impurities on the surface of the PCB board. After cleaning and positioning, the PCB board is conveyed to the bottom of the laminating assembly 2. The belt conveyor 1 stops, and the laminating assembly is started to laminate and cut the upper surface of the PCB board. The belt conveyor 1 is then started again, and the PCB board after lamination and cutting continues to be conveyed out of the equipment by the belt conveyor 1.
