Description

Technical Field

[0001] This utility model relates to the field of circuit board processing technology, specifically to an auxiliary feeding device for circuit boards. Background Technology

[0002] During the production of printed circuit boards (PCBs), it is often necessary to feed materials into the PCB production equipment, which requires the use of auxiliary feeding devices. These auxiliary feeding devices are designed to improve the efficiency and quality of the feeding process in PCB production, and include lifting feeding devices.

[0003] The existing auxiliary feeding device for circuit boards still has the following problems when in use: Although the lifting feeding device can adjust the height of the circuit board feeding structure according to the height of the production equipment to be suitable for processing equipment of different heights, so that the operator can pick up the circuit boards with less effort, when feeding between it and the specific circuit board production equipment, it still requires manual handling of the circuit boards. In mass production, frequent manual replenishment is required, which increases labor intensity. In addition, the linkage between it and the circuit board production equipment is poor, which poses a risk of material accumulation or flow interruption. Utility Model Content

[0022] Please see Figures 1-4In this embodiment of the present invention, an auxiliary feeding device for a circuit board includes a positioning frame mechanism 1. The positioning frame mechanism 1 is equipped with a lifting mechanism 3 and a feeding mechanism 2. The positioning frame mechanism 1 includes two rectangular frames 11 arranged symmetrically in an upper and lower configuration. Two frame plates 12 are symmetrically fixedly connected between the two rectangular frames 11. Two positioning grooves 14 are symmetrically opened on the inner sidewalls of both the front and rear ends of the upper rectangular frame 11. A guide groove 15 is opened at the center of the top of the upper rectangular frame 11. The lifting mechanism 3 includes positioning slide bars 31 slidably connected in the four positioning grooves 14. The four positioning slide bars 31 are fixedly connected to each other. The same bracket 32 ​​is fixedly connected, and a positioning block 33 is fixedly connected to each of the four corners of the top of the bracket 32. The front and rear ends of the bracket 32 ​​are equipped with independent power components. The whole adopts a feeding structure design with automated assisted feeding. It includes a positioning frame mechanism 1 that matches the feeding end of the production equipment. The positioning frame is equipped with a lifting mechanism 3 that can position and assemble the multi-layer rack of circuit boards. In addition, a pushing and feeding mechanism 2 is set in conjunction with the lifting mechanism 3. The circuit boards in the multi-layer rack can be fed into the feeding end of the circuit board production equipment in sequence. The overall automation level is high and it can realize linkage with the production equipment.

[0023] The feeding mechanism 2 includes a push block 24 slidably connected in a guide groove 15 on one side. One end of the push block 24 is provided with a pushing component and a positioning component. The pushing component includes an electric guide rail 21 fixedly installed in the middle of the upper part of one side frame plate 12. An electric slider 22 is slidably installed on the outside of the electric guide rail 21. The top of the electric slider 22 is fixedly connected to the push block 24 through an L-shaped frame 23. The positioning component includes a mounting frame 25 fixedly connected to the other side of the top of the L-shaped frame 23. A positioner 26 is fixedly installed at the other end of the mounting frame 25. The positioner 26 can perform positioning work. That is, when the lifting mechanism 3 lifts the multi-layer placement rack of circuit boards, when the top layer of circuit boards is flush with the push block 24, the electric slider 22 on the electric guide rail 21 can move, driving the L-shaped frame 23 to push the circuit board and send it into the feeding end of the circuit board processing equipment through the guide groove 15 on the other side.

[0024] A set of mounting bases 13 is fixedly connected to each of the front and rear ends of the lower rectangular frame 11. There are two mounting bases 13 in a set and they are arranged symmetrically. The guide groove 15 on the other side can be aligned with the feeding end of the circuit board processing equipment for matching and linkage. The overall circuit board auxiliary feeding device is fixedly installed through the mounting bases 13.

[0025] A connecting block 34 is fixedly connected to the middle of each end of the bracket 32. The two connecting blocks 34 are slidably connected to the top of the lower rectangular frame 11. The power component includes a motor 35 fixedly installed at the front end of the upper rectangular frame 11. A screw 36 is fixedly connected to the bottom drive end of the motor 35. A stop block is fixedly connected to the top of the screw 36. A threaded hole 37 for threaded connection of the screw 36 is opened between the upper and lower side walls of the front connecting block 34. The lifting mechanism 3 is equipped with an independent limit lifting component and an independent power component. That is, the screw 36 can be driven to rotate by the motor 35. Since the screw 36 is threadedly connected to the threaded hole 37 of the connecting block 34, it can drive the connecting block 34 to rise and fall, thereby driving the bracket 32 ​​and the multi-layer circuit board placement rack positioned on it to rise and fall. The power component only provides lifting power, while its limit lifting component plays a limiting role in the rise and fall, ensuring the stability of the lifting mechanism 3 when lifting the multi-layer circuit board placement rack.

[0026] The working principle of this utility model is as follows: The overall design adopts a feeding structure with automated auxiliary feeding, which includes a positioning frame mechanism 1 that matches the feeding end of the production equipment. It can align the guide groove 15 on the other side with the feeding end of the circuit board processing equipment for matching and linkage. The overall circuit board auxiliary feeding device is fixedly installed through the mounting base 13. The positioning frame is equipped with a lifting mechanism 3 that can position and assemble a multi-layer circuit board placement rack. Specifically, a positioning block 33 is fixedly connected to each of the four corners of the top of the bracket 32. The positioning block 33 can be inserted into the bottom hole of the multi-layer circuit board placement rack to realize the multi-layer placement of circuit boards. The circuit board is placed on the bracket 32 ​​and is equipped with a feeding mechanism 2 to push the material. The positioner 26 can perform positioning work. That is, when the lifting mechanism 3 lifts the multi-layer placement rack of circuit boards, it stops lifting when the top layer of circuit boards is flush with the push block 24. The electric slider 22 on the electric guide rail 21 can move, driving the L-shaped frame 23 to push the circuit boards and send them into the feeding end of the circuit board processing equipment through the guide groove 15 on the other side. In this way, the circuit boards in the multi-layer placement rack can be sent into the feeding end of the circuit board production equipment in sequence. The overall automation level is high and it can realize linkage with the production equipment.
