Then, a robotic arm or other transfer device is used to move the carrier board to the processing position of the processing unit for processing. The whole process is cumbersome and has low processing efficiency. Utility Model Content

[0004] In view of the above problems, the purpose of this utility model is to provide a feeding device for circuit board processing, which aims to solve the problems of cumbersome operation and low processing efficiency of existing feeding devices for circuit board processing.

[0005] The present invention adopts the following technical solution:

[0006] The feeding device for circuit board processing includes a worktable with a conveyor belt and a lifting frame. The conveyor belt is located inside the lifting frame. The worktable has a lifting assembly that drives the lifting frame to move vertically. A blocking assembly is located in front of the lifting frame on the worktable.

[0007] Furthermore, the workbench has a slot, and a fixed seat is provided on the workbench within the slot. The lifting frame is slidably mounted on the fixed seat. The lifting assembly includes a lead screw rotatably mounted on the fixed seat. The bottom of the lead screw extends through the bottom surface of the lifting frame, and a driven wheel is provided at the top of the lead screw. The workbench is also equipped with a lifting motor, and the drive shaft of the lifting motor is equipped with a driving wheel. The driving wheel and the driven wheel are fitted with a belt.

[0008] Furthermore, the lifting frame is provided with a pair of front and rear clamping columns facing upwards, and the position of the rear clamping column is higher than that of the front clamping column. The bottom surface of the lifting frame is provided with a clamping cylinder, and the drive shaft of the clamping cylinder is located on the clamping frame, wherein the front clamping column is installed on the clamping frame.

[0009] Furthermore, the blocking assembly includes a blocking cylinder, the drive shaft of the blocking cylinder is provided with a U-shaped frame, the conveyor belt is located inside the U-shaped frame, and a pair of left and right blocking posts are provided on the U-shaped frame.

[0010] The beneficial effects of this utility model are: the device effectively prevents the carrier plate and the circuit board from shifting position during the feeding process by using the limiting notch on the bottom surface of the carrier plate to cooperate with the limiting strip on the conveyor belt, and the shallow groove on the top surface of the carrier plate to limit the circuit board, thus ensuring the accuracy and stability of the feeding.

[0015] To make the objectives, technical solutions, and advantages of this utility model patent clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0016] To illustrate the technical solution described in this utility model, specific embodiments are described below.

[0017] For ease of explanation, only the parts relevant to the embodiments of this utility model are shown.

[0018] Combination Figure 1-4 As shown, the feeding device for circuit board processing includes a workbench 1, a conveyor belt 2 on the workbench 1, a lifting frame 3 on the workbench 1, the conveyor belt 2 located inside the lifting frame 3, a lifting assembly on the workbench, the lifting assembly driving the lifting frame to move vertically, a blocking assembly on the workbench 1 located in front of the lifting frame 3, a carrier plate 4 placed on the conveyor belt 2, a plurality of shallow grooves 5 opened on the top surface of the carrier plate 4, and the shallow grooves 5 are used to place the circuit board, a limiting notch 6 opened on the bottom surface of the carrier plate 4, and a limiting strip 7 formed in the middle of the conveyor belt 2 facing upward, the limiting strip 7 located inside the limiting notch 6.

[0019] When using this device, start the conveyor belt and place the carrier board containing the circuit board on the conveyor belt. Due to the cooperation of the limiting strip and the limiting notch, the carrier board can be stably transported on the conveyor belt. At the same time, the circuit board is confined in the shallow groove of the carrier board and will not shake or shift.

[0020] As a preferred structure, such as Figure 3 The lifting frame 3 is provided with a pair of front and rear clamping columns facing upwards, wherein the front clamping column is marked as 81 and the rear clamping column is marked as 82. The position of the rear clamping column 82 is higher than that of the front clamping column 81. The bottom surface of the lifting frame 3 is provided with a clamping cylinder 9, and the drive shaft of the clamping cylinder 9 is located on the clamping frame 10, wherein the front clamping column 81 is mounted on the clamping frame 10.

[0021] Before the carrier plate is placed on the conveyor belt, the two rear clamping posts are slightly higher than the conveyor belt surface, and the two front clamping posts are slightly lower than the conveyor belt surface, with the two rear clamping posts forming a stop. Once the carrier plate is conveyed to the processing position, it is stopped by the two rear clamping posts. Simultaneously, a blocking assembly forms a stop, preventing subsequent carrier plates from entering. Then, the lifting frame moves upward a short distance, supporting the carrier plate, which remains on the conveyor belt. Driven by the clamping cylinders, the clamping frame moves backward until both pairs of clamping posts clamp the carrier plate, leaving the circuit board on the carrier plate ready for processing.

[0022] After the circuit board is processed, the front clamping posts release their clamping force on the carrier plate, the lifting frame moves downward, and the height of both the front and rear pairs of clamping posts is slightly lower than the surface of the conveyor belt. The carrier plate moves backward under the conveyor belt's transport. Immediately afterwards, the lifting frame moves upward, the two rear clamping posts re-establish their blocking positions, the blocking components release their blocking positions, and the next carrier plate carrying the circuit board enters the processing position. The rear clamping posts block this carrier plate, and the next processing cycle begins.

[0023] In this structure, such as Figure 3 The workbench 1 has a slot 11, and a fixed seat 12 is provided on the workbench 1 within the slot 11. The lifting frame 3 is slidably mounted on the fixed seat 12. The lifting assembly includes a lead screw 13 rotatably mounted on the fixed seat. The bottom of the lead screw 13 extends through the bottom surface of the lifting frame 3, and a driven wheel 14 is provided at the top of the lead screw 13. The workbench 1 is also provided with a lifting motor 15. The drive shaft of the lifting motor 15 is provided with a drive wheel 16, and the drive wheel 16 and the driven wheel 14 are fitted with a belt 17.

[0024] When the lifting frame needs to move vertically, the lifting motor starts and drives the driven wheel to rotate via the drive wheel and belt, which in turn causes the lead screw to rotate. Since the lifting frame is slidably mounted on the fixed base and cooperates with the lead screw, the lead screw drives the lifting frame to move vertically up and down during rotation, thus realizing the lifting function of the lifting frame.

[0025] As a specific structure, the blocking assembly includes a blocking cylinder 18, the drive shaft of the blocking cylinder 18 is provided with a U-shaped frame 19, the conveyor belt 2 is located inside the U-shaped frame 19, and a pair of left and right blocking posts 20 are provided on the U-shaped frame 19.

[0026] When the blocking assembly needs to block subsequent pallets, the blocking cylinder is activated, causing the U-shaped frame to rise, raising the pair of left and right blocking posts above the conveyor belt surface, thus blocking the subsequent pallets from moving forward. When it is time to release subsequent pallets, the blocking cylinder drive shaft causes the U-shaped frame to descend, lowering the blocking posts below the conveyor belt surface, allowing the subsequent pallets to continue moving forward with the help of the conveyor belt.

[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
