[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Reference Figure 1 - Figure 3 , the utility model provides an embodiment: an FPC board automatic sheet-feeding device, including a shell 1, which provides external protection for the entire automatic sheet-feeding device and is used to support the robot arm 3 and the slide rail 2. The inner wall of the shell 1 is provided with a robot arm 3, which is responsible for driving the suction cup member 6 on the installation frame 4 to perform precise position adjustment. By moving in different directions, the suction cup member 6 can be moved to the position where the sheet-feeding operation is required, so as to realize the actions of grabbing and placing the FPC board. This technology is a prior art, so it is not described in detail. The slide rail 2 is fixedly connected to the lower side of the shell 1 below the robot arm 3. The slide rail 2 is provided with multiple groups for placing FPC boards waiting for sheet-feeding and boards for installing FPC boards. A mounting frame 4 is provided on the lower side of the robot arm 3 as a mounting carrier for the adsorption mechanism and disassembly assembly, which plays the role of connecting and supporting these components. The outside of the mounting frame 4 is provided with an adsorption mechanism.

[0031] Furthermore, the adsorption mechanism includes an adjustment component and a limit component. The adjustment component includes a slide groove 53, which provides a track for the sliding of the slider 51, so that the slider 51 can move linearly on the inner wall of the lower side of the installation frame 4, thereby adjusting the position of the suction cup 6 to adapt to the FPC boards waiting for sheeting at different intervals. The slide groove 53 is opened through the inner wall of the lower side of the installation frame 4, and the inner wall of the slide groove 53 is slidably connected to the slider 51. The slider 51 moves along the slide groove 53 under the action of the bidirectional threaded rod 52, driving the suction cup 6 to adjust its position, thereby achieving accurate adsorption of FPC boards at different intervals. The inner wall of the slider 51 is provided with a suction cup 6, and the connection port on it is connected to the air pipe. By generating suction, the FPC board can be firmly adsorbed. So that the robotic arm 3 can move it to the designated position for film arrangement operation. This technology is existing technology, so it will not be described in detail. The inner wall of the mounting frame 4 is rotatably connected with a bidirectional threaded rod 52. Rotating the bidirectional threaded rod 52 can make the two sliders 51 move inward or outward at the same time, thereby adjusting the distance between the two suction cups 6 to adapt to FPC boards of different spacing sizes and improve the versatility of the device. At the same time, a connecting part connected to the motor output shaft is provided on the right side of the bidirectional threaded rod 52, and the bidirectional threaded rod 52 is driven to rotate by an external motor. This technology is existing technology, so it will not be described in detail. The outer side of the bidirectional threaded rod 52 is threadedly connected to the inner wall of the rear side of the slider 51, and two groups of sliders 51 and suction cups 6 are provided.

[0032] Reference Figure 3 The limit assembly includes a cylinder 71, which drives the limit block 72 to move through its output shaft to release the limit on the bidirectional threaded rod 52. The cylinder 71 is fixedly connected to the left side of the mounting frame 4. The lower side of the output shaft of the cylinder 71 is fixedly connected to the limit block 72. The friction force is increased by the inner wall of the groove made of rubber material to limit the bidirectional threaded rod 52 to prevent the bidirectional threaded rod 52 from accidentally rotating during operation, thereby ensuring the stability of the position of the suction cup part 6 and the reliability of adsorbing the FPC board. A convex strip 73 is provided on the left side of the bidirectional threaded rod 52. The convex strip 73 is provided with multiple groups for increasing friction. A groove is provided on the lower side of the limit block 72. The groove on the lower side of the limit block 72 fits on the outer side of the convex strip 73, and the inner wall of the groove on the lower side of the limit block 72 is set to rubber material.

[0033] Reference Figure 2 and Figure 3A disassembly component is provided on the upper side of the mounting frame 4, and the disassembly component includes a mounting slot 81. The mounting slot 81 is opened on the outer wall of the lower side of the robotic arm 3. The mounting frame 4 is connected to the robotic arm 3 by being plugged into the inner wall of the mounting slot 81. The robotic arm 3 is plugged into the inner wall of the mounting slot 81. A bolt 82 is provided on the outside of the mounting frame 4. The bolt 82 passes through the mounting frame 4 and is threadedly connected to the inner wall of the robotic arm 3, which is used to firmly fix the mounting frame 4 on the robotic arm 3. At the same time, it is also convenient for disassembly when needed, and it is convenient for maintenance and replacement of the mounting frame 4 and components. There are multiple groups of mounting slots 81, and multiple groups of mounting slots 81 are evenly arranged on the left and right sides of the lower part of the robotic arm 3, which can improve the stability of the installation of the mounting frame 4.

[0034] Working principle: During use, when it is necessary to adapt to FPC boards with different intervals, first start the cylinder 71 so that its output shaft drives the limit block 72 to move upward, releasing the limit on the bidirectional threaded rod 52. At this time, the motor rotates the bidirectional threaded rod 52 on the inner wall of the mounting frame 4 through the connecting piece. The rotation of the bidirectional threaded rod 52 causes the two sliders 51 to move inward or outward at the same time in the slide groove 53. The suction cup part 6 on the inner wall of the slider 51 adjusts its position as the slider 51 moves, so that FPC boards with different intervals can be accurately adsorbed, thereby improving the versatility of the device.

[0035] Restarting the cylinder 71 causes the output shaft of the cylinder 71 to drive the limit block 72 to move downward, and the friction force generated by the pressure limits the bidirectional threaded rod 52, thereby ensuring the stability of the position of the suction cup 6 and the reliability of adsorbing the FPC board.

[0036] When the installation frame 4 and related components need to be maintained or replaced, the bolts 82 can be unscrewed to remove the installation frame 4 from the robot arm 3, making maintenance and replacement operations easier.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
