[0037] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation to the present invention.

[0038] As Figures 1-6 Shown is a schematic diagram of the structure of the PCB board assembly device for the LED strip lamp of the present application. As shown in the figure, the device includes a frame 1, a PCB board feeding component 2 located on one side of the frame 1, an aluminum bottom positioning component 3 provided on the frame 1 for carrying and fixing the aluminum bottom 900 of the PCB board 800 to be inserted, a transmission component 4 provided on the frame 1 for conveying the PCB board 800 from the PCB board feeding component 2, a PCB board positioning component 5 located at the front end of the movement direction of the transmission component 4 for positioning the PCB board 800 conveyed by the transmission component 4, and a transfer drive component 6 provided on the frame 1 for transferring the PCB board 800 on the PCB board positioning component 5 to the front end of the aluminum bottom positioning component 3 and prompting the PCB board 800 to move to penetrate into the aluminum bottom 900 for assembly. With such a setting, it effectively solves the problem that in the past, it was necessary to manually load one by one, and then manually insert the PCB boards into the aluminum bottom one by one, with low efficiency and qualification rate, and realizes assembly automation. Among them, the transmission component 4 uses an ordinary transmission belt.

[0039] Specifically, as Figures 1-3As shown, the transfer drive assembly 6 includes a moving manipulator 61 for grasping the PCB 800 on the PCB positioning assembly 5 and causing the PCB 800 to move and penetrate into the aluminum bottom 900, a first motion track 62 for the moving manipulator 61 to move back and forth between the aluminum bottom positioning assembly 3 and the PCB positioning assembly 5, and a first drive mechanism 63 for providing power for the movement of the moving manipulator 61 on the first motion track 62 and the movement of the moving manipulator 61 to cause the PCB 800 to move.

[0040] See further Figure 3 , the moving manipulator 61 includes a mechanical claw composed of two rollers 611 arranged in parallel and capable of approaching or separating from each other under the drive of the first drive mechanism 63. An annular groove 611A with a longitudinal width not less than the thickness of the PCB 800 is provided on the roller 611. The roller 611 can rotate horizontally around its own central axis under the drive of the first drive mechanism 63. Both sides of the PCB 800 can be respectively clamped in the annular groove 611A when the two rollers 611 approach each other, and friction is generated between the PCB 800 and the annular groove 611A during the rotation of the roller 611 to cause the PCB 800 to move towards the aluminum bottom 900 under the action of the frictional force and penetrate into the aluminum bottom 900.

[0041] It can be imagined that in order to promote the forward movement of the PCB, one of the rollers 611 has to rotate counterclockwise on the horizontal plane and the other has to rotate clockwise on the horizontal plane, so that each generates a frictional force towards the movement direction of the transfer assembly 4 on the PCB, so as to promote the forward movement of the PCB 800 under the action of the frictional force.

[0042] The longitudinal width of the annular groove 611A is not less than the thickness of the PCB, which can be used to transfer PCBs 800 with different thicknesses, and the distance between the rollers 611 is variable, which is also convenient for grasping PCBs 800 with different widths, so that the device is suitable for different types of PCBs, solving the trouble of constantly changing the production line for different types of lamps in the past, saving manpower and material resources, and improving production efficiency.

[0043] Since the installation positions of the PCB 800 on different aluminum bottoms 900 are different, for example, some aluminum bottoms require the PCB to form an angle of 30 degrees or 45 degrees with the horizontal plane after installation, and the transfer assembly 4 can only make the PCB perform a translational movement parallel to the horizontal plane. Obviously, it cannot be assembled into the aluminum bottom 900. To solve this problem, the device further includes an angle rotation mechanism 7. The moving manipulator 61 is fixedly connected to the angle rotation mechanism 7 and can rotate synchronously with the angle rotation mechanism 7 to adjust the angle of the PCB 800 relative to the horizontal plane so that the PCB 800 can smoothly penetrate into the aluminum bottom 900.

[0044] Specifically, as Figure 3As shown in the figure, the angle rotation mechanism 7 includes a rotation part 71 fixedly connected to the upper end of the moving manipulator 61, and a driving component 72 connected to the rotation part 71 and capable of driving the rotation part 71 to rotate.

[0045] As Figure 4 shown in the figure, the PCB board positioning component 5 includes a first transfer track 51 that provides a transfer channel for the PCB board 800 from the transfer component 4 in the raised state and descends when the PCB board 800 stops moving, a first clamping and pressing component 52 located at the rear end of the first transfer track 51, and a second clamping and pressing component 53 located at the front end of the first transfer track 51.

[0046] The second clamping and pressing component 53 is provided with a baffle 531 for blocking the movement of the PCB board 800, and the first clamping and pressing component 52 and the second clamping and pressing component 53 synchronously clamp both sides of the PCB board 800 and press and position both sides of the PCB board 800 when the first transfer track 51 is in the descending state. In this embodiment, the baffle 531 is arranged at the front end of the second clamping and pressing component 53.

[0047] Both the first clamping and pressing component 52 and the second clamping and pressing component 53 include first clamping cylinders 5A arranged in parallel and capable of approaching each other to clamp the PCB board 800, and first vertical cylinder plates 5B arranged on the first clamping cylinders 5A and capable of pressing down the side of the PCB board 800 to position the PCB board 800. Similarly, the first clamping cylinders 5A can approach or separate from each other, enabling the device to be applicable to PCB boards of different widths and improving the applicability of the assembly device.

[0048] As Figure 5 shown in the figure, the PCB board loading component 2 includes a tray 21 for carrying the PCB board 800 located in the loading area S, and a transfer component 22 capable of moving the PCB board 800 on the tray 21 to the transfer component 4 and transferring the emptied tray 21 from the loading area S to the unloading area Q.

[0049] The transfer component 22 includes a lifting manipulator 221 that lifts and transfers the PCB board 800 on the tray 21 to the PCB board 800 on the transmission component 4, a clamping cylinder assembly 222 that clamps the empty tray 21 and transfers it to the blanking area Q, a second motion track 223 that allows the lifting manipulator 221 to move back and forth between the loading area S and the transmission component 4 and the clamping cylinder assembly 222 to move back and forth between the loading area S and the blanking area Q, and a second driving mechanism 224 that provides power for the lifting manipulator 221 and the clamping cylinder assembly 222. Correspondingly, the transmission component 4 is located between the loading area S and the blanking area Q, and the moving direction of the transmission component 4 is parallel to the length direction of the PCB board 800 on the tray 21. In this way, only the second motion track 223 needs to be set, and the lifting manipulator 221 and the clamping cylinder assembly 222 share a motion track, that is, they share the second motion track 223, saving equipment costs.

[0050] See Figure 6 , the lifting manipulator 221 includes a connecting rod 221A that can move on the second motion track 223, and lifting shovels 221B that are arranged at intervals on the connecting rod 221A and can lift the PCB board 800 by inserting into the bottom of the PCB board 800 located on the tray 21.

[0051] Correspondingly, the clamping cylinder assembly 222 includes a cross bar 222A that can move on the second motion track 223, and clamping cylinders 222B that are arranged at intervals on the cross bar 222A and can clamp the protruding parts (not shown by reference numerals in the figure) on the tray 21.

[0052] At the same time, the aluminum bottom positioning component 3 includes a second clamping cylinder 31 and a third clamping cylinder 32 that are arranged at intervals in the moving direction of the transmission component 4 to respectively clamp the ends of the aluminum bottom 900, specifically as Figure 2 shown. It should be noted that in this application, the first driving mechanism 63, the second driving mechanism 224, and the driving component 72 are all servo motors. Of course, they can also be other devices that can provide power, as long as they can provide power for driving.

[0053] The PCB board is transported to the transmission component by the lifting manipulator, and then continues to be transported through the first transmission track and is positioned and pressed by the cooperation of the first clamping and pressing component and the second clamping and pressing component. Then, the positioned PCB board is grabbed by the mechanical claw composed of two rollers arranged in parallel, and the friction force generated between the rollers and the PCB board during the movement of the rollers is used to promote the PCB board to penetrate into the aluminum bottom, which well realizes the automatic insertion of the PCB board and improves the work efficiency and production qualification rate;

[0054] The width of the annular groove on the roller is not less than the thickness of the PCB board. The two rollers can approach or separate from each other, and even the separable movement of the transverse cylinders on the first clamping and pressing component and the second clamping and pressing component can facilitate the matching of PCB boards with different widths, improving the applicability of the assembly equipment. The automated setting of the PCB board loading component strengthens the automation of PCB board production and improves the production efficiency.

[0055] Although the embodiments of the present invention have been shown and described, those skilled in the art can understand that various changes, modifications, substitutions, and deformations can be made to these embodiments without departing from the principles and purposes of the present invention. The scope of the present invention is defined by the claims and their equivalents.
