Description

Technical Field

[0001] This utility model relates to the field of circuit board pin technology, and in particular to a self-locking circuit board solderless pin device. Background Technology

[0002] Self-locking solderless pin-mounting devices are a highly efficient and reliable method for connecting electronic components, particularly suitable for automated production lines. Through a special structural design, these devices enable quick and secure pin-mounting onto circuit boards without soldering, thereby improving production efficiency and product quality. Widely used in automated production lines, especially in wave soldering processes, self-locking solderless pin-mounting devices are suitable for semi-automated and fully automated production. They significantly reduce labor requirements, increase production efficiency, lower production costs, ensure product quality, and eliminate safety hazards.

[0003] In existing technology, the device fixes the circuit board requiring pin insertion onto a self-locking structure inside the device. The self-locking structure secures the circuit board, and a starting device moves the self-locking device, simultaneously inserting pins into the circuit board. However, this device lacks continuous feeding capabilities, resulting in significant disadvantages in production efficiency. Because it cannot operate continuously, it requires frequent stops and starts during production, extending the production cycle and reducing overall efficiency. Each stop and start consumes additional time, especially under tight production schedules. Such frequent starts and stops significantly increase preparation and completion times, further prolonging the production cycle. Therefore, an improved self-locking circuit board solderless pin insertion device is needed to address these issues. Utility Model Content

[0004] To overcome the fact that self-locking circuit board solderless pin insertion devices cannot achieve continuous and uninterrupted operation, these devices need to be frequently stopped and started during the production process. This not only prolongs the production cycle but also reduces the overall production efficiency. Each stop and start consumes additional time, especially when production tasks are urgent. Such frequent start and stop will significantly increase the production preparation time and completion time.

[0005] The technical solution of this utility model is as follows: a self-locking circuit board solderless pin insertion device, including a conveying platform, a connecting bracket and a fixing component. A support base is fixedly connected to the bottom of the conveying platform, and a fixing suction cup is provided at the bottom of the support base. The pin insertion device body is provided inside the conveying platform, and an adjusting connecting seat is provided at the top of the conveying platform. The fixing component is located inside the adjusting connecting seat. The connecting bracket is fixedly connected to the front of the conveying platform. A first motor is fixedly connected to the bottom of the connecting bracket. A rotation guide structure is fixedly connected to the output end of the first motor. A first rotating shaft is fixedly connected to the output end of the rotation guide structure. The first rotating shaft is rotatably connected inside the conveying platform. A first pulley is fixedly connected to the outside of the first rotating shaft. A second pulley is rotatably connected inside the conveying platform. A transmission connecting belt is driven to the outside of the second pulley. The transmission connecting belt is driven to the outside of the first pulley.

[0006] Preferably, there are two first rotating shafts, and the two first rotating shafts are symmetrically connected inside the conveying platform.

[0007] Preferably, the conveyor platform has a groove at the corresponding position of the transmission connecting belt, and the transmission connecting belt moves inside the groove.

[0008] Preferably, a fixed connecting block is fixedly connected to the outer side of the conveying platform, a sliding limiting rod is slidably connected inside the fixed connecting block, a limiting fixing ring is fixedly connected to the inner side of the sliding limiting rod, a limiting support seat is fixedly connected to the inner side of the limiting fixing ring, a return spring is fixedly connected between the limiting fixing ring and the fixed connecting block, and a limiting support plate is fixedly connected to the top of the conveying platform.

[0009] Preferably, several sliding limit rods are provided, and these sliding limit rods are evenly slidably connected inside the fixed connecting block.

[0010] Preferably, the fixing component includes a connecting hinge fixedly connected to the top of the transmission connecting belt, an adjusting connecting seat rotatably connected inside the transmission connecting belt, a second motor fixedly connected to the left side of the adjusting connecting seat, a first threaded rod fixedly connected to the output end of the second motor, a sliding connecting seat slidably connected to the external thread of the first threaded rod, a third motor fixedly connected to the front side of the sliding connecting seat, a second threaded rod fixedly connected to the output end of the third motor, an adjusting connecting block slidably connected to the external thread of the second threaded rod, and a fixing extrusion plate fixedly connected to the top of the adjusting connecting block.

[0011] Preferably, the adjusting connecting seat has a groove at the corresponding position of the sliding connecting seat, and the sliding connecting seat slides inside the groove.

[0012] The beneficial effects of this utility model are as follows: Compared with the self-locking circuit board solderless pin insertion device that cannot be continuously processed, the rotation of the first rotating shaft drives the first pulley to rotate. The rotation of the first pulley and the rotation of the second pulley drive the transmission belt to transmit power. The circuit board installed on the adjusting connecting seat is continuously transported through the transmission belt, realizing continuous and uninterrupted work, shortening the production cycle, improving the overall production efficiency, and shortening the production preparation time and completion time. This effectively prevents the self-locking circuit board solderless pin insertion device from having to frequently stop and start during the production process due to its inability to achieve continuous and uninterrupted work.

There are two first rotating shafts 804, which are symmetrically connected inside the conveying platform 1. The transmission of the two first rotating shafts 804 makes the transmission more stable. The conveying platform 1 has a groove at the corresponding position of the transmission connecting belt 807. The transmission connecting belt 807 moves inside the groove. The groove at the corresponding position of the transmission connecting belt 807 inside the conveying platform 1 makes the transmission connecting belt 807 more stable during transmission.

[0021] Please see Figure 1 - Figure 3In this embodiment, a fixed connecting block 809 is fixedly connected to the outer side of the conveying platform 1. A sliding limiting rod 810 is slidably connected inside the fixed connecting block 809. A limiting fixing ring 811 is fixedly connected to the inner side of the sliding limiting rod 810. A limiting support seat 812 is fixedly connected to the inner side of the limiting fixing ring 811.

A fixing pressing plate 908 is fixedly connected to the top of the adjusting connecting block 907. By placing the circuit board inside the adjusting connecting seat 5, the circuit is driven... The second motor 902 causes its first threaded rod 903 to rotate inside the adjusting connecting seat 5. With the first threaded rod 903 threadedly connected to the sliding connecting seat 904, the sliding connecting seat 904 is driven to move inward, so that the adjusting connecting block 907 contacts the circuit board and is fixed. Then, the third motor 905 drives its second threaded rod 906 to rotate inside the sliding connecting seat 904. With the adjusting connecting block 907 threadedly connected to the second threaded rod 906, the fixing pressing plate 908 on the adjusting connecting block 907 moves inward and contacts the circuit board to fix it. The pin insertion device body 4 is used to insert wires into the circuit board. The adjusting connecting seat 5 has a groove at the corresponding position of the sliding connecting seat 904. The sliding connecting seat 904 slides inside the groove. The groove at the corresponding position of the sliding connecting seat 904 inside the adjusting connecting seat 5 limits the sliding connecting seat 904 when it slides inside the groove.

[0023] During operation, the circuit board is placed inside the adjusting connector 5. The second motor 902 is driven to rotate the first threaded rod 903 inside the adjusting connector 5. With the first threaded rod 903 threadedly connected to the sliding connector 904, the sliding connector 904 moves inward, causing the adjusting connector 907 to contact and fix the circuit board. Then, the third motor 905 is driven to rotate the second threaded rod 906 inside the sliding connector 904. With the adjusting connector 907 threadedly connected to the second threaded rod 906, the fixing pressing plate 908 on the adjusting connector 907 moves inward to contact and fix the circuit board.

The limit support seat 812 supports the adjusting connecting seat 5 of the pin insertion device body 4 during operation. The pin insertion device body 4 performs wire insertion processing on the circuit board.

[0024] Through the above steps, the first motor 802 drives the rotation guide structure 803 to rotate the first rotating shaft 804. The rotation of the first rotating shaft 804 drives the first pulley 805 to rotate. The rotation of the first pulley 805, in conjunction with the rotation of the second pulley 806, drives the transmission connecting belt 807 to transmit power. The transmission connecting belt 807 continuously transports the circuit board installed on the adjusting connecting seat 5. This solves the problem that self-locking circuit board solderless pin insertion devices cannot achieve continuous and uninterrupted operation. Such devices require frequent stops and starts during the production process, which not only prolongs the production cycle but also reduces the overall production efficiency. Each stop and start consumes extra time, especially when the production task is urgent. Such frequent starts and stops significantly increase the production preparation time and completion time.
