Description

Technical Field

[0001] This utility model relates to the field of transfer machine technology, specifically a high-precision dual-track transfer machine. Background Technology

[0002] Transfer machines are automated equipment used for material handling and positioning, widely applied in electronics manufacturing, logistics sorting, and other fields. Traditional transfer machines typically employ a single-track design, using conveyor belts or robotic arms to transfer materials. However, with the miniaturization and increasing precision of electronic components, especially in the production of SMT circuit boards, higher demands are placed on the accuracy, efficiency, and flexibility of transfer machines. Existing transfer machines often suffer from limited adjustment range, poor adaptability, and low efficiency when handling the sorting of multi-sized materials and high-precision positioning.

[0003] Currently, some dual-track transfer machines are designed to adjust the conveyor belt spacing using bidirectional threaded rods or employ diversion components to achieve material diversion. However, some devices still have shortcomings, such as insufficient precision and stability of the adjustment structure, making it difficult to meet the high-precision positioning requirements of SMT circuit boards, or poor coordination between the diversion component and the horizontal moving structure, resulting in low material transfer efficiency. Therefore, this paper proposes a high-precision, high-efficiency dual-track transfer machine capable of rapid adjustment, accurate sorting, and stable transmission to meet the high standards required by modern electronics manufacturing. Utility Model Content

It solves the problems of poor positioning accuracy, insufficient stability, poor coordination, and low transfer efficiency due to the inability to operate continuously.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-precision dual-track transfer machine, including a frame, with an inlet and an outlet respectively opened on both sides of the frame, and a first frame and a second frame arranged inside the frame, with the first frame and the second frame arranged in parallel, and a square top frame provided on the top of the second frame, with a transfer adjustment structure for moving SMT circuit boards on the top of the square top frame;

[0006] The top of the rack is provided with a fixed frame, the top of the fixed frame is provided with a support frame, the top of the support frame is provided with a shunt component for moving the SMT circuit board to different transfer adjustment structures, and the top of the fixed frame is provided with a horizontal moving structure for driving the displacement of the shunt component.

[0007] Furthermore, the frame has viewing windows on both the front and back for observing the operation of the internal equipment, and a control module is also provided on the front of the frame.

[0008] Furthermore, the transplanting adjustment structure includes a servo motor, two sets of adjustment frames, multiple transmission tracks, a worm gear, three bidirectional threaded rods, and three worm wheels. The servo motor is located on one side of the top of the square top frame, and the worm gear is connected to the output shaft of the servo motor for transmission. The two sets of adjustment frames are located on the top of the square top frame. Fixed plates are provided on both sides of the square top frame, and the three bidirectional threaded rods are respectively movably disposed between the two fixed plates via bearings. The three worm wheels are respectively fixedly disposed on the three bidirectional threaded rods, and all three worm wheels mesh with the worm gear. The bottoms of the two sets of adjustment frames are slidably disposed on the top of the square top frame via sliding blocks. The multiple transmission tracks are respectively disposed in the grooves on the top of the two sets of adjustment frames, and multiple transmission shafts are provided inside the grooves to drive the transmission tracks to rotate.

[0009] Furthermore, the bottom of the two sets of adjustment frames is fixedly provided with a transmission block that is threadedly connected to the three bidirectional threaded rods. The transmission block drives the two sets of adjustment frames to shorten the distance between them. The top side of the square top frame is also provided with a fixed seat that forms a stable support with the other end of the worm gear. The top of both sets of adjustment frames is provided with a calibration receiver.

[0010] Furthermore, the horizontal moving structure includes a geared motor, a one-way threaded rod, and a limiting groove. The one-way threaded rod is disposed on the top of the fixed frame, the geared motor is disposed on one side of the support frame, and the output end of the geared motor is also connected to one end of the one-way threaded rod.

Detailed Implementation

[0022] 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.

[0023] Please see Figure 1-5 This embodiment of a high-precision dual-track transfer machine includes a frame 1. The frame 1 has an inlet 2 and an outlet 3 on its two sides respectively. The frame 1 has a first frame 4 and a second frame 5 inside. The first frame 4 and the second frame 5 are fixed inside the frame 1 by bolts and serve to support the fixed frame 11 and the square top frame 14. The top of the second frame 5 is provided with a fixed plate 10, and the top of the fixed plate 10 is provided with a transfer adjustment structure 9 for transferring SMT circuit boards.

[0024] The top of rack 4 is provided with a fixed frame 11 for supporting the frame of the horizontal moving structure 8. The top of the fixed frame 11 is provided with a support frame 13. The top of rack 5 is provided with a square top frame 14. The top of the support frame 13 is provided with a diversion component 7 for moving the SMT circuit board to different transfer adjustment structures 9. The top of the fixed frame 11 is provided with a horizontal moving structure 8 for driving the diversion component 7 to move.

[0025] The frame 1 has viewing windows on both the front and back to observe the operation of the internal equipment. The front of the frame 1 also has a control module, which controls the transfer adjustment structure 9, the diversion component 7 and the horizontal movement structure 8 to perform different programs to realize the continuous transfer process of SMT circuit boards.

[0026] It should be noted that the frame 1 is made of high-strength aluminum alloy, and the inlet 2 and outlet 3 on both sides are equipped with transmission devices that connect with the diversion component 7 and the transfer adjustment structure 9 to ensure the smooth entry and exit of SMT circuit boards.

[0027] In this embodiment, the transplanting adjustment structure 9 includes a servo motor 901, two sets of adjustment frames 902, multiple transmission tracks 903, a worm gear 904, three bidirectional threaded rods 905, and three worm wheels 906. The servo motor 901 is located on the top side of the fixed plate 10 and serves as the main power source for driving the transplanting adjustment structure 9. The worm gear 904 is connected to the output shaft of the servo motor 901 and serves as a transmission rod for power steering. The two sets of adjustment frames 902 are located on the top of the square top frame 14 and serve as transmission frames to restrict the movement of the SMT circuit board. Fixed plates 10 are provided on both sides of the square top frame 14. Three bidirectional threaded rods 905 are respectively movably mounted between two fixed plates 10 via bearings, serving as the main shaft for adjusting the distance between the two sets of adjusting frames 902. Three worm gears 906 are respectively fixedly mounted on the three bidirectional threaded rods 905, serving as meshing wheels for power steering, and all three worm gears 906 mesh with the worm 904. The bottoms of the two sets of adjusting frames 902 are respectively slidably mounted on the top of the square top frame 14 via sliding sliders. The sliding sliders restrict the horizontal movement direction of the adjusting frames 902. Multiple transmission tracks 903 are respectively mounted in the grooves on the top of the two sets of adjusting frames 902, and multiple drive shafts are installed inside the grooves to drive the transmission tracks 903 to rotate.

[0028] Among them, the bottom of the two sets of adjustment frames 902 is fixedly provided with transmission blocks that are threadedly connected to three bidirectional threaded rods 905. The transmission blocks drive the two sets of adjustment frames 902 to shorten the distance between them. The top side of the square top frame 14 is also provided with a fixed seat that forms a stable support with the other end of the worm gear 904. The top of the two sets of adjustment frames 902 is provided with a calibration receiver 12.

[0029] It should be noted that each set of adjustment frame 902 is equipped with a motor behind it to drive the transmission shaft to drive the transmission track 903 to rotate. The worm (904) passes through the central shaft of the three worm wheels (906). The distance between adjacent worm wheels is an integer multiple of the worm pitch to ensure synchronous meshing without phase difference. Copper bushing bearings are added to both ends of the worm, and the radial runout is ≤0.02mm.

[0030] Specifically, when the transfer adjustment structure 9 is needed to adapt to the transfer width of different models of SMT circuit boards, the servo motor 901 drives the worm gear 904 to rotate, which in turn drives the three turbines 906 meshing with the worm gear 904 to rotate. The turbines 906 are fixed on three bidirectional threaded rods 905, thus causing the three bidirectional threaded rods 905 to rotate. At the same time, the transmission blocks at the bottom of the two sets of adjustment frames 902 are threadedly connected to the three bidirectional threaded rods 905, so that the two sets of adjustment frames 902 can complete the relative horizontal movement of the two sets of adjustment frames 902 under the restriction of the slide block, thereby achieving the function of adjusting the width. After the SMT circuit board enters the conveyor belt 903 at the top of the middle of each set of adjustment frames 902, the conveyor belt 903 drives the SMT circuit board to move, thereby achieving the function of adapting to the transfer of different models of SMT circuit boards.

[0031] In this embodiment, the horizontal moving structure 8 includes a reduction motor 801, a one-way threaded rod 802, and a limiting groove 803. The one-way threaded rod 802 is disposed on the top of the fixed frame 11 and serves as the main shaft for transmission. The reduction motor 801 is disposed on one side of the support frame 13 and serves as the drive for the diversion component 7 to move horizontally. The output end of the reduction motor 801 is also connected to one end of the one-way threaded rod 802. The limiting groove 803 is opened on the top of the support frame 13 and is a slot that restricts the movement position of the diversion component 7.

[0032] It should be noted that the bottom of the diversion component 7 is provided with a threaded hole that is threadedly connected to the one-way threaded rod 802. When the one-way threaded rod 802 rotates, it drives the diversion component 7 to move horizontally under the limit of the limiting groove 803.

[0033] Specifically, the drive geared motor 801 rotates, which in turn drives the one-way threaded rod 802 to rotate, thereby enabling the movable plate 702, which is threadedly connected to the one-way threaded rod 802, to achieve horizontal displacement under the action of the limiting groove 803, thus achieving the effect of adjusting the position of the diversion component 7.

[0034] In this embodiment, the diversion component 7 includes a progressive motor 701, a movable plate 702, and multiple transmission tracks 703. The movable plate 702 is disposed on the top of the fixed frame 11 and serves as a carrier for the SMT circuit board. The top of the movable plate 702 is also provided with multiple track grooves for the transmission tracks 703 to drive. The multiple transmission tracks 703 are respectively driven and disposed inside the multiple track grooves, serving as a transmission component for moving the SMT circuit board into or out of the movable plate 702.

[0035] Multiple track grooves are equipped with multiple drive shafts, and the multiple drive shafts are connected to the drive shafts through the output shaft of the advance motor 701. The drive shafts drive the transmission track 703. The top four corners of the moving plate 702 are equipped with calibration sensors 6 to connect to the signal transmitting device of the calibration receiver 12.

[0036] It should be noted that the calibration sensor (6) uses an infrared laser emitter, and the calibration receiver (12) is equipped with a high-sensitivity photoelectric sensor to form a closed-loop feedback system. When the circuit board position shifts, the change in the receiver signal strength triggers the control module to adjust the transmission speed in real time, achieving a positioning accuracy of ±0.05mm.

[0037] Specifically, when the diversion component 7 needs to transfer the SMT circuit board to different track processes, the diversion component 7 can be moved to different transfer adjustment structure 9 tracks by the horizontal moving structure 8. Then, the driving motor 701 drives multiple conveyor belts 703 to transfer the SMT circuit board on top, thereby moving the SMT circuit board to the transfer adjustment structure 9 track to achieve the function of transferring the SMT circuit board to different track processes.
