DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Specifically, a dispensing device for processing a flexible circuit board includes a base 1, a first connecting plate 2 is installed on the base 1, a dispensing mechanism 3 is installed on the first connecting plate 2, two second connecting plates 4 are relatively installed on the base 1, a first servo motor 5 is installed on one of the second connecting plates 4, a first threaded rod 6 is connected to the output shaft of the first servo motor 5, the first threaded rod 6 is rotatably installed on the base 1, and a workbench 7 is threadedly connected to the first threaded rod 6, two first connecting blocks 8 are installed on the base 1, the same positive and negative screw rod 9 is rotatably connected between the two first connecting blocks 8, and one end of the positive and negative screw rod 9 is connected to the output of the second servo motor 10 At the end, two positioning plates 11 are threadedly connected to the forward and reverse screw rods 9, and the two positioning plates 11 are both located on the workbench 7. The workbench 7 is provided with two accommodating grooves 12, and the two accommodating grooves 12 are adapted to the corresponding positioning plates 11. Two second connecting blocks 13 are installed on the base 1, and a third servo motor 14 is installed on one of the second connecting blocks 13. A second threaded rod 15 is connected to the output shaft of the third servo motor 14, and one end of the second threaded rod 15 away from the third servo motor 14 is rotatably connected to the other second connecting block 13. A scraper 16 is threadedly connected to the second threaded rod 15, and the bottom wall of the scraper 16 can contact the positioning plate 11.

[0022] When it is necessary to clean the residual glue on the workbench 7 and the positioning plate 11, the staff first turns on the second servo motor 10, and the second servo motor 10 drives the positive and negative screw rods 9 to rotate, so that the two positioning plates 11 threadedly mounted on the positive and negative screw rods 9 move to coincide with the positions of the two receiving grooves 12 opened on the workbench 7, and then starts the first servo motor 5, and the first servo motor 5 rotates to drive the first threaded rod 6 to rotate, so that the workbench 7 threadedly connected to the first threaded rod 6 moves upward until the two positioning plates 11 are placed in the receiving grooves 12, and the two positioning plates 11 and the workbench 7 are aligned. The top surface is flush, and the second servo motor 10 is turned on at this time. The second servo motor 10 drives the second threaded rod 15 to rotate, so that the scraper 16 threadedly connected to the second threaded rod 15 moves along the direction of the second threaded rod 15, and contacts with the workbench 7 and the two positioning plates 11 when moving, so as to achieve the purpose of removing the colloid on the workbench 7 and the positioning plates 11. The device can synchronously complete the cleaning work of the workbench 7 and the positioning plates 11 through the scraper 16, avoiding the operation of manually disassembling the workbench 7 and the positioning plates 11 for manual cleaning, greatly saving labor costs and improving work efficiency.

[0023] Specifically, in this embodiment, a first limiting shaft 17 is installed on the base 1, and one end of the first limiting shaft 17 away from the base 1 is connected to the second connecting plate 4 away from the first threaded rod 6, and one end of the workbench 7 away from the first threaded rod 6 is slidably connected to the first limiting shaft 17. When the first threaded rod 6 rotates, it will drive the workbench 7 threaded thereon to rotate synchronously. However, since the other end of the workbench 7 is slidably connected to the first limiting shaft 17, the workbench 7 is restricted, so that the workbench 7 can only move in the vertical direction, thereby avoiding the rotation of the workbench 7.

[0024] Specifically, in this embodiment, two third connecting blocks 18 are installed on the base 1, and the two third connecting blocks 18 are arranged opposite to the two first connecting blocks 8. The same sliding rod 19 is installed on the two third connecting blocks 18, and the ends of the two positioning plates 11 away from the first connecting blocks 8 are slidably connected to the sliding rod 19. When the positive and negative screw rods 9 drive the two positioning plates 11 threaded thereon to rotate, the sliding rod 19 restricts the two positioning plates 11, so that the two positioning plates 11 can only move along the direction of the sliding rod 19, thereby avoiding the occurrence of malfunctions during the movement of the positioning plates 11.

[0025] Specifically, in the present embodiment, a limiting plate 20 is installed at one end of the scraper 16 away from the second threaded rod 15, and a limiting groove 21 is provided on the base 1. The limiting plate 20 is adapted to the limiting groove 21, so that the scraper 16 can be slidably connected to the base 1 through the adaptability of the limiting plate 20 and the limiting groove 21, thereby preventing the second threaded rod 15 from driving the scraper 16 to rotate and causing the scraper 16 to fail to work normally.

[0026] Specifically, in the present embodiment, a positive threaded hole 22 and a negative threaded hole 23 are respectively provided at one end of the two positioning plates 11 close to the positive and negative screw rods 9. The positive threaded hole 22 and the negative threaded hole 23 are adapted to the threads at both ends of the positive and negative screw rods 9, so that the two positioning plates 11 can be threadedly connected to the two ends of the positive and negative screw rods 9 through the positive threaded hole 22 and the negative threaded hole 23 respectively. When the positive and negative screw rods 9 rotate, the two positioning plates 11 can be driven to approach or move away from each other, thereby achieving the position limitation of the flexible circuit board and driving the two positioning plates 11 to move to the top of the accommodating groove 12.

[0027] Specifically, in the present embodiment, a rotating hole 24 is provided on the second connecting plate 4 near the first threaded rod 6, and the rotating hole 24 is adapted to the first threaded rod 6, so that the first threaded rod 6 can be connected to the second servo motor 10 through the rotating hole 24, thereby providing power support for the rotation of the first threaded rod 6 and ensuring smooth transmission of power.

[0028] Specifically, in this embodiment, a fan 25 is rotatably installed on the scraper 16, so that the scraper 16 can drive the fan 25 to move synchronously when it moves. The colloid and dust scraped off during the movement of the scraper 16 can be sucked away by the fan 25 for one-time cleaning, which effectively improves the cleaning efficiency.

[0029] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
