Description

Technical Field

[0001] This utility model relates to the field of PCB boards, and in particular to a high-reliability PCB board transfer fixture. Background Technology

[0002] Printed circuit boards (PCBs) are indispensable core components in modern electronic devices. PCBs provide robust physical support for electronic components and achieve effective connections between them through carefully designed conductive paths, forming a complete circuit system. Due to their flexibility and customizability, PCBs are widely used in various types of electronic devices. However, PCB production typically involves multiple steps, each requiring the transfer of the PCB from one workstation to another; therefore, PCB transfer is particularly important.

[0003] An existing patent (application number 202421175642.0) discloses a PCB board conveying device. This utility model relates to the field of PCB board conveying technology, including a conveyor belt. Motion mechanisms are provided on both sides of the conveyor belt, and a collection box is provided at the bottom of one end of the conveyor belt. The motion mechanism includes a fixed rod, a horizontal threaded rod at the top of the fixed rod, and a baffle above the horizontal threaded rod. This PCB board conveying device, through the rotation of the horizontal threaded rod, causes two connecting rods to move simultaneously, reducing the distance between the two baffles and bringing the rollers into contact. When the PCB board contacts the rollers, sliding friction is changed to rolling friction, reducing friction and damage to the PCB board. Furthermore, the vertical rod moves along with the conveyor belt and subsequently contacts the PCB board, pushing it to move and preventing the PCB board from getting stuck. This restricts the PCB board and prevents positional deviation during conveying.

[0004] Most existing PCB boards are transported by conveyor belts. However, different models of PCB boards vary in size, and the limiting mechanism on the conveyor belt is difficult to adjust as needed. PCB boards of different models are prone to shifting during transport, which limits the use of the device. In addition, the conveyor belt is also prone to dust and stains, which will also affect the transport of PCB boards. Utility Model Content

[0005] Therefore, it is necessary to provide a highly reliable PCB board conveying fixture to address the technical problems of the difficulty in adjusting the limiting mechanism on the conveyor belt according to the needs of different PCB board models, and the fact that the conveyor belt is also prone to dust and stains, which can affect the conveying of PCB boards.

[0006] A high-reliability PCB board conveying fixture includes a first support base and a second support base. A first support leg is fixedly installed on the lower front of both the first and second support bases. A cleaning device is fixedly installed between the two first support legs. A second support leg is fixedly installed on the lower rear of both the first and second support bases. A first fixing frame is fixedly installed on the upper middle of both the first and second support bases. A limit device is fixedly installed on the right end of the first fixing frame. A second fixing frame is fixedly installed at both the front and rear of the upper end of the base. A conveying device is installed between the first and second support bases. A controller is fixedly installed at the middle of the right end of the first support base. The limiting device includes a first servo motor. A positive and negative screw is fixedly installed at the output end of the first servo motor. A connecting seat is installed on both the positive and negative threads of the positive and negative screws. The positive and negative screws are rotatably installed between the left and right inner walls of the first fixing frame. Several limiting rollers are rotatably installed at the lower ends of the two connecting seats.

[0007] In one embodiment, a slider is fixedly installed on the upper end of each of the two connecting seats, a groove is opened at the lower end of the first fixing frame, the slider is located in the groove, the two connecting seats are slidably installed on the lower end of the first fixing frame via the slider, and the servo motor is fixedly installed on the right end of the first fixing frame.

[0008] The No. 1 servo motor drives the positive and negative screws to rotate within the No. 1 fixed frame. At this time, the connecting seats on the positive and negative threads of the positive and negative screws move closer to each other, so that the distance between the two sets of limit rollers at the lower end of the two connecting seats can be adjusted according to the size of the PCB board. This not only improves the applicability of the device, but also prevents the PCB board from shifting during transmission by limiting the position of the limit rollers.

[0009] In one embodiment, the cleaning device includes a receiving box with a fixed base at its front end. Mounting screws are installed at both the left and right ends of the fixed base. The receiving box is fixedly mounted between two support legs using the mounting screws. Two mounting plates are fixedly mounted on the lower inner wall of the receiving box. A first mounting bracket and a second mounting bracket are respectively fixedly mounted on the upper ends of the two mounting plates. A cleaning brush is fixedly mounted on the upper end of the first mounting bracket, and a scraper is fixedly mounted on the upper end of the second mounting bracket.

[0010] When the conveyor belt rotates, the scraper first scrapes off the particles adhering to the conveyor belt, and then the cleaning brush sweeps away the dust and other impurities on the conveyor belt, thus ensuring that the conveyor belt has a good cleanliness when it is operating. In addition, by loosening the mounting screws, the two No. 1 support legs of the receiving box can be pulled out, which makes it easier to clean the receiving box.

[0011] In one embodiment, the conveying device includes a first drive roller, a second servo motor, and a second drive roller. A conveyor belt is rotatably mounted on the outer surfaces of the first and second drive rollers. Two support rollers are movably mounted through the middle of the right end of the conveyor belt. The output end of the second servo motor is fixedly connected to the first drive roller. The second servo motor is fixedly mounted at the front right end of the first support base. The first drive roller, the second drive roller, and the two support rollers are all rotatably mounted between the first support base and the second support base.

[0012] The PCB board is placed between two sets of limit rollers. At this time, the No. 2 servo motor drives the No. 1 drive roller, thereby pushing the conveyor belt to transport the PCB board on it.

[0013] In one embodiment, the lower end of the second fixing frame has a second sliding groove, and two second sliders are slidably installed in the second sliding groove.

[0014] In one embodiment, both the first fixing frame and the second fixing frame are U-shaped.

[0015] In one embodiment, the first mounting bracket and the second mounting bracket are respectively fixedly mounted on the upper end of the two mounting plates by means of screws.

[0016] In one embodiment, the upper surface of the cleaning brush and scraper contacts the lower surface of the conveyor belt.

[0017] In one embodiment, there is a gap between the limiting roller and the conveyor belt.

[0018] In one embodiment, the two second sliders are respectively fixedly installed on the upper ends of the two connecting seats.

[0019] The aforementioned high-reliability PCB board conveying fixture first uses a servo motor on a limiting device to drive the forward and reverse screws to rotate within a fixed frame. This causes the connecting seats on the forward and reverse threads of the screws to move closer together, allowing the distance between the two sets of limiting rollers at the lower ends of the connecting seats to be adjusted according to the size of the PCB board. This not only improves the applicability of the device but also prevents the PCB board from shifting during conveying. Furthermore, the rotation of the limiting rollers at the lower end of the connecting seats reduces friction between the PCB board and the limiting rollers, facilitating PCB board conveying. Next, the PCB board is placed between the two sets of limiting rollers, and then conveyed... The second servo motor on the device drives the first drive roller, which in turn pushes the conveyor belt to transport the PCB board on it. In addition, when the conveyor belt rotates, the scraper on the cleaning device first scrapes off the particles adhering to the conveyor belt, and then the cleaning brush sweeps away the dust and other impurities on the conveyor belt, thus ensuring that the conveyor belt has a good cleanliness during operation. Moreover, by loosening the mounting screws, the two first support legs of the receiving box can be pulled out, which facilitates the cleaning of the receiving box. In addition, the first and second mounting brackets are also fixed on the two mounting plates by screws, so the cleaning brush and scraper can also be removed for cleaning or replacement.

[0030] Please refer to the following: Figures 1 to 5 This utility model provides a high-reliability PCB board conveying fixture, including a first support base 1 and a second support base 6. A first support leg 9 is fixedly installed on the lower front of both the first support base 1 and the second support base 6. A cleaning device 3 is fixedly installed between the two first support legs 9. A second support leg 10 is fixedly installed on the lower rear of both the first support base 1 and the second support base 6. A first fixing frame 5 is fixedly installed on the upper middle of both the first support base 1 and the second support base 6. A limit device 2 is fixedly installed on the right end of the first fixing frame 5. The upper front of the first support base 1 and the upper end of the second support base 6 are connected to the upper... A second fixed frame 7 is fixedly installed at the rear. A conveying device 4 is installed between the first support seat 1 and the second support seat 6. A controller 8 is fixedly installed at the middle of the right end of the first support seat 1. The limiting device 2 includes a first servo motor 20. A positive and negative screw 21 is fixedly installed at the output end of the first servo motor 20. A connecting seat 22 is installed on both the positive and negative threads of the positive and negative screw 21. The positive and negative screw 21 is rotatably installed between the left inner wall and the right inner wall of the first fixed frame 5. Several limiting rollers 23 are rotatably installed at the lower end of the two connecting seats 22. The first fixed frame 5 and the second fixed frame 7 are both U-shaped.

[0031] A first slider 24 is fixedly installed on the upper end of each of the two connecting seats 22. A first groove 25 is opened at the lower end of the first fixing frame 5. The first slider 24 is located in the first groove 25. The two connecting seats 22 are slidably installed on the lower end of the first fixing frame 5 through the first slider 24. The first servo motor 20 is fixedly installed on the right end of the first fixing frame 5.

[0032] The controller 8 is electrically connected to the first servo motor 20 and the second servo motor 41. The first servo motor 20 drives the positive and negative screws 21 to rotate in the first fixed frame 5. At this time, the connecting seats 22 on the positive and negative threads of the positive and negative screws 21 move closer to each other, so that the distance between the two sets of limit rollers 23 at the lower end of the two connecting seats 22 can be adjusted according to the size of the PCB board. This not only improves the applicability of the device, but also prevents the PCB board from shifting during the conveying process by limiting the position of the limit rollers 23.

[0033] The cleaning device 3 includes a receiving box 30. A fixing base 31 is fixedly installed at the front end of the receiving box 30. The fixing base 31 is equipped with mounting screws 32 at both the left and right ends. The receiving box 30 is fixedly installed between two No. 1 support legs 9 by the mounting screws 32. Two mounting plates 33 are fixedly installed on the lower inner wall of the receiving box 30. A No. 1 mounting bracket 34 and a No. 2 mounting bracket 35 are respectively fixedly installed on the upper end of the two mounting plates 33. A cleaning brush bristle 36 is fixedly installed on the upper end of the No. 1 mounting bracket 34, and a scraper 37 is fixedly installed on the upper end of the No. 2 mounting bracket 35. The No. 1 mounting bracket 34 and the No. 2 mounting bracket 35 are fixedly installed on the upper end of the two mounting plates 33 by screws.

[0034] When the conveyor belt 40 rotates, the scraper 37 first scrapes off the particles adhering to the conveyor belt 40, and then the cleaning brush 36 cleans the dust and other impurities on the conveyor belt 40, thereby ensuring that the conveyor belt 40 has a good cleanliness when it is in operation. Moreover, by loosening the mounting screws 32, the two No. 1 support feet 9 of the receiving box 30 can be pulled out, which makes it easier to clean the receiving box 30.

[0035] The conveying device 4 includes a first drive roller 42, a second servo motor 41, and a second drive roller 43. A conveyor belt 40 is rotatably mounted on the outer surfaces of the first drive roller 42 and the second drive roller 43. Two support rollers 44 are movably mounted in the middle of the right end of the conveyor belt 40. The output end of the second servo motor 41 is fixedly connected to the first drive roller 42. The second servo motor 41 is fixedly mounted at the front right end of the first support seat 1. The first drive roller 42, the second drive roller 43, and the two support rollers 44 are all rotatably mounted between the first support seat 1 and the second support seat 6. There is a gap between the limiting roller 23 and the conveyor belt 40. The upper surfaces of the cleaning brush bristles 36 and the scraper 37 are in contact with the lower surface of the conveyor belt 40.

[0036] The PCB board is placed between two sets of limiting rollers 23. At this time, the No. 2 servo motor 41 drives the No. 1 drive roller 42, thereby pushing the conveyor belt 40 to transport the PCB board on it.

[0037] The second fixed frame 7 has a second sliding groove 50 at its lower end, and two second sliders 51 are slidably installed in the second sliding groove 50; the two second sliders 51 are respectively fixedly installed on the upper ends of the two connecting seats 22.

[0038] The second slider 51 is fixedly installed on the connecting seat 22 to further support the connecting seat 22 and prevent the connecting seat 22 from easily shaking or shifting.

[0039] This utility model provides a highly reliable PCB board conveying fixture. Before use, the controller 8 is connected to an external power supply. Then, the first servo motor 20 on the limiting device 2 drives the forward and reverse screws 21 to rotate within the first fixed frame 5. At this time, the connecting seats 22 on the forward and reverse threads of the forward and reverse screws 21 move closer to each other, so that the distance between the two sets of limiting rollers 23 at the lower end of the two connecting seats 22 can be adjusted according to the size of the PCB board. This not only improves the applicability of the device but also prevents the PCB board from shifting during conveying. In addition, the limiting rollers 23 rotate at the lower end of the connecting seats 22, thereby reducing the friction between the PCB board and the limiting rollers 23, facilitating the conveying of the PCB board. Then, the PCB board is placed between the two sets of limiting rollers 23. The second servo motor 41 on the conveyor device 4 drives the first drive roller 42, thereby pushing the conveyor belt 40 to convey the PCB board on it. In addition, when the conveyor belt 40 rotates, the scraper 37 on the cleaning device 3 first scrapes off the particles adhering to the conveyor belt 40, and then the cleaning brush 36 cleans the dust and other impurities on the conveyor belt 40, thereby ensuring that the conveyor belt 40 has a good cleanliness when it is operating. Moreover, by loosening the mounting screws 32, the receiving box 30 can be pulled out with two first support feet 9, which facilitates the cleaning of the receiving box 30. In addition, the first mounting bracket 34 and the second mounting bracket 35 are also fixed on the two mounting plates 33 by screws, so the cleaning brush 36 and the scraper 37 can also be removed for cleaning or replacement.

[0040] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0041] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
