Technical Field
[0001] This utility model relates to the field of pulley tracks, and in particular to a connecting device for high-speed multi-segment pulley tracks. Background Technology
[0002] In AOI (Automated Optical Inspection) equipment, pulley track systems are widely used for PCB board transport. Traditional transport methods typically use chains or belts. While simple, these methods have several drawbacks. For example, chains or belts are slow and have low accuracy, and they can easily cause vibrations in the PCB board, affecting inspection accuracy. Furthermore, the track height of existing systems is too high, resulting in an excessive distance between the PCB board and the light source, leading to poor imaging. To address these issues, a device is needed that can improve transport accuracy, reduce vibration, lower track height, and effectively connect multiple track segments.
[0003] In the existing technology, the device requires installation during use. The installation connects the rails together to facilitate the sliding of the pulleys inside the rails. The installation is done by bolting, which requires the use of tools to tighten the bolts and install multiple rail sections. This is inconvenient and reduces the efficiency of equipment installation. Therefore, it is necessary to improve the high-speed multi-section pulley rail connection device to solve the above problems. Utility Model Content
[0004] To overcome the problem that the connecting device for high-speed multi-section pulley rails requires the use of tools to fix the bolts, and the installation of multiple rail sections is achieved by turning the bolts with tools, which brings inconvenience to the installation and reduces the efficiency of equipment installation.

A moving device is provided at the bottom of the connecting base, and a supporting fixing plate is provided at the top of the connecting base. A sliding track is fixedly connected to the top of the supporting fixing plate. The height adjustment component is provided at the top of the connecting base. The sliding limit rod is fixedly connected inside the sliding track. A limit compression ring is slidably connected to the outside of the sliding limit rod. A return spring is fixedly connected between the limit compression ring and the sliding track. A sliding limit block is slidably connected to the outside of the sliding limit rod.

The snap-fit limit block snaps into the inside of the snap-fit plate. The return spring pushes the limit compression ring, and the limit compression ring pushes the sliding limit block to slide inside the sliding track.
[0006] Preferably, there are two sliding limit rods, and the two sliding limit rods are symmetrically and fixedly connected inside the sliding track.
[0007] Preferably, the snap-fit plate has a snap-fit groove inside the snap-fit limiting block, and the snap-fit limiting block snaps into the snap-fit groove.
[0008] Preferably, a push rod is fixedly connected to the front of the sliding limit block, the push rod slides inside the sliding track, a push button is fixedly connected to the front of the push rod, a connecting support plate is fixedly connected to the bottom of the sliding track, a fixed limit plate is fixedly connected to the bottom of the sliding track, the connecting support plate is snapped into the inside of the fixed limit plate, and a fixing bolt is threaded into the inside of the fixed limit plate.
[0009] Preferably, the fixing bolt contacts the connecting support plate, and the sliding rail has a groove at the corresponding position of the push rod, so that the push rod slides inside the groove.
[0010] Preferably, the height adjustment assembly includes an adjusting telescopic rod, which is fixedly connected between the support plate and the connecting base. A fixed connecting seat is fixedly connected to the top of the connecting base. A rotating worm gear is rotatably connected inside the fixed connecting seat.

[0011] Preferably, the connecting base has a groove at the corresponding position of the adjustment handle, and the adjustment handle rotates inside the groove.
[0012] The beneficial effects of this utility model are as follows: Compared with the connecting device for multi-pulley tracks that are only connected by bolts, the reset spring pushes the limiting compression ring to slide outside the sliding limiting rod, and the limiting compression ring pushes the sliding limiting block to slide inside the sliding track. The sliding of the sliding limiting block causes the locking limiting block to engage inside the locking plate, thus connecting the device. This makes the equipment installation more convenient and improves the installation efficiency. It effectively prevents the inconvenience caused by fixing multiple track sections by twisting bolts with tools. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0020] Please see Figure 1 - Figure 5This utility model provides an embodiment of a connecting device for a high-speed multi-segment pulley track, including a connecting base 1, a sliding limit rod 804, and a height adjustment component. A moving device 2 is provided at the bottom of the connecting base 1, and a supporting fixing plate 3 is provided at the top of the connecting base 1. A sliding track 4 is fixedly connected to the top of the supporting fixing plate 3. The height adjustment component is located at the top of the connecting base 1. The sliding limit rod 804 is fixedly connected inside the sliding track 4, and a limit compression ring is slidably connected to the outside of the sliding limit rod 804. 805, a return spring 806 is fixedly connected between the limiting compression ring 805 and the sliding rail 4. A sliding limiting block 807 is slidably connected to the outside of the sliding limiting rod 804. A snap-fit limiting block 810 is fixedly connected to the front of the sliding limiting block 807. A snap-fit plate 811 is movably connected inside the sliding rail 4. The snap-fit limiting block 810 snaps into the inside of the snap-fit plate 811. The limiting compression ring 805 is pushed by the set return spring 806, and the sliding limiting block 807 is pushed by the limiting compression ring 805 in the sliding rail. 4. Internal sliding: The moving device 2 moves the equipment to a suitable position. The supporting plate 3 supports the sliding track 4. The reset spring 806 pushes the limiting compression ring 805 to slide outside the sliding limiting rod 804. The limiting compression ring 805 pushes the sliding limiting block 807 to slide inside the sliding track 4. The sliding of the sliding limiting block 807 causes the locking limiting block 810 to engage with the inside of the locking plate 811. The sliding limiting rod 804 has two... Two sliding limit rods 804 are symmetrically fixedly connected inside the sliding track 4. The two sliding limit rods 804 provide stability when sliding in the groove. The snap-fit plate 811 has a snap-fit groove inside the snap-fit limit block 810. The snap-fit limit block 810 snaps into the groove. The snap-fit limit block 810 is snapped into the groove by the snap-fit groove inside the snap-fit plate 811 corresponding to the position of the snap-fit limit block 810. The snap-fit limit block 810 is snapped into the inside of the snap-fit plate 811 to fix the snap-fit plate 811.
[0021] Please see Figure 2 - Figure 3In this embodiment, a push rod 808 is fixedly connected to the front of the sliding limit block 807. The push rod 808 slides inside the sliding track 4. A push button 809 is fixedly connected to the front of the push rod 808. A connecting support plate 801 is fixedly connected to the bottom of the sliding track 4. A fixed limit plate 802 is fixedly connected to the bottom of the sliding track 4. The connecting support plate 801 is snapped into the inside of the fixed limit plate 802. A fixing bolt 803 is threaded inside the fixed limit plate 802. By snapping the connecting support plate 801 into the inside of the fixed limit plate 802 and twisting the fixing bolt 803, the fixing bolt 803 comes into contact with the connecting support plate 801, thereby fixing the devices together. The fixing bolt 803 comes into contact with the connecting support plate 801. A groove is provided in the sliding track 4 at the position corresponding to the push rod 808. The push rod 808 slides inside the groove. The groove provided in the sliding track 4 at the position corresponding to the push rod 808 limits the push rod 808 when it slides inside the groove.
[0022] Please see Figure 4 - Figure 5 In this embodiment, the height adjustment assembly includes an adjusting telescopic rod 901, which is fixedly connected between the support fixing plate 3 and the connecting base 1. A fixed connecting seat 902 is fixedly connected to the top of the connecting base 1. A rotating worm gear 903 is rotatably connected inside the fixed connecting seat 902. An adjusting handle 904 is fixedly connected to the right side of the rotating worm gear 903. A rotating worm wheel 905 is rotatably connected inside the connecting base 1 and meshes with the outside of the rotating worm gear 903. A rotating threaded rod 906 is fixedly connected inside the rotating worm wheel 905, and a threaded cylinder 907 is threadedly connected to the outside of the rotating threaded rod 906. The threaded cylinder 907 is fixedly connected to the bottom of the support fixing plate 3. The adjustment handle 904 is rotated to make the worm gear 903 rotate inside the fixed connecting seat 902. The worm gear 903 meshes with the worm wheel 905, causing the worm wheel 905 to rotate inside the connecting base 1. The rotation of the worm wheel 905 causes the threaded rod 906 to rotate inside the threaded cylinder 907. The threaded cylinder 907 pushes the support fixing plate 3 to move. The connecting base 1 has a groove at the corresponding position of the adjustment handle 904. The adjustment handle 904 rotates inside the groove. The groove at the corresponding position of the adjustment handle 904 inside the connecting base 1 makes the adjustment handle 904 stable when rotating in the groove.
[0023] During operation, the reset spring 806 pushes the limiting compression ring 805 to slide outside the sliding limiting rod 804, and the limiting compression ring 805 pushes the sliding limiting block 807 to slide inside the sliding track 4. The sliding of the sliding limiting block 807 causes the locking limiting block 810 to engage with the locking plate 811, thus connecting the device. When disassembly is required, pressing the press button 809 causes the push rod 808 to push the sliding limiting block 807 to slide inside the sliding track 4. The sliding of the limiting compression ring 805 causes the locking limiting block 810 to disengage from the locking plate 811, completing the disassembly. During installation, the fixing bolt 803 is twisted to make it contact the connecting support plate 801, thus fixing the devices together. When adjusting the height, the adjusting handle 904 is rotated to make the worm gear 903 rotate inside the fixed connecting seat 902. The worm gear 903 meshes with the worm wheel 905, causing the worm wheel 905 to rotate inside the connecting base 1. The rotation of the worm wheel 905 causes the threaded rod 906 to rotate inside the threaded cylinder 907. Under the limit of the adjusting telescopic rod 901, the threaded cylinder 907 pushes the supporting fixing plate 3 for adjustment.
[0024] Through the above steps, the reset spring 806 pushes the limiting compression ring 805 to slide outside the sliding limiting rod 804, and the limiting compression ring 805 pushes the sliding limiting block 807 to slide inside the sliding track 4. The sliding of the sliding limiting block 807 causes the locking limiting block 810 to engage inside the locking plate 811, thus connecting the device. This solves the problem that when fixing bolts in the connecting device for high-speed multi-section pulley tracks, tools are needed to install the multi-section track by turning the bolts with tools, which brings inconvenience to the installation and reduces the efficiency of equipment installation.
