Description

Technical Field

[0001] This utility model belongs to the field of circuit board processing technology, and in particular relates to a conveying device for circuit board processing. Background Technology

[0002] In the circuit board manufacturing industry, automated conveyor systems are key equipment connecting various production processes, and their performance directly affects processing efficiency and product quality. Currently, in the circuit board manufacturing process, conveyor systems are needed to transfer materials between processes, while clamping mechanisms are required to ensure the precise stopping of circuit boards at processing, inspection, and other workstations.

[0003] Traditional conveying devices lack precise and flexible clamping capabilities. During circuit board transport, they need to be precisely positioned at the designated processing location and clamped by a clamping mechanism. However, existing clamping mechanisms often exhibit lag or uneven force, failing to quickly and effectively secure the circuit board. This inefficient clamping method not only makes it difficult to ensure the stability of the circuit board during processing but also easily leads to scratches on the circuit board surface and edge damage due to improper clamping force control. Utility Model Content

[0004] In view of the above problems, the purpose of this utility model is to provide a conveying device for circuit board processing, which aims to solve the problem that the existing conveying devices for circuit board processing cannot quickly and effectively clamp and fix the circuit board.

[0017] 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.

[0018] To illustrate the technical solution described in this utility model, specific embodiments are described below.

[0019] For ease of explanation, only the parts relevant to the embodiments of this utility model are shown.

[0020] Combination Figure 1-4 As shown, the conveying device for circuit board processing includes a workbench 1, a belt conveyor on the workbench 1, a clamping mechanism on the belt conveyor, and a fixed frame 3 respectively installed on the frame 2.1 on both sides of the belt conveyor. The fixed frame 3 is provided with two pairs of rotating blocks 4, and a connecting block 5 is rotatably provided on the rotating blocks 4 on the same side. The two connecting blocks 5 are provided with pressure plates 51. A rotating shaft 6 is fixed between a pair of rotating blocks 4. A rotating gear 7 is provided in the middle of the rotating shaft 6. A fixed seat 8 is provided on the frame 2.1 opposite to the rotating gear 7. A spur rack 9 is slidably provided on the fixed seat 8. The spur rack 9 meshes with the rotating gear 7. A push cylinder 10 is provided on the fixed seat 8. The drive shaft of the push cylinder 10 is connected to the spur rack 9 through a push plate 11.

[0021] When using this device, first start the belt conveyor to transport the circuit board. Once the circuit board is transported to the processing station, the belt conveyor stops, and the clamping mechanism clamps the circuit board. After the circuit board is processed, the belt conveyor restarts to transport the processed circuit board to the next station.

[0022] When the clamping mechanism clamps the circuit board, two push cylinders are activated simultaneously, driving the rack and pinion to slide on the fixed seat via the push plate. Since the rack and pinion mesh with the rotating gear, the sliding of the rack and pinion causes the rotating gear to rotate, which in turn causes the rotating shaft to rotate. The rotation of the shaft causes the rotating block to rotate, and the rotating block, through the connecting block, causes the pressure plate to move inward and downward, finally pressing the circuit board. This achieves the clamping of the circuit board placed on the belt conveyor, preventing the circuit board from shaking or shifting during transport and ensuring the accuracy of the processing position. This efficient clamping method ensures the stability of the circuit board during processing and also avoids scratches on the circuit board surface and edge damage caused by improper clamping force control.

[0023] As a preferred structure, such as Figure 1The belt conveyor includes a pair of left and right belt conveyor platforms 21. A pair of adjusting screws 22 are rotatably mounted on the worktable 1. The adjusting screws 22 have a pair of oppositely arranged threaded sections. A pair of adjusting sleeves 23 are mounted on the adjusting screws 22. The belt conveyor platforms 21 are mounted on the two adjusting sleeves 23 on the same side. A driven wheel 24 is mounted on the same end of the two adjusting screws 22. A motor base 25 is mounted on the worktable 1. An adjusting motor 26 is mounted on the motor base 25. A drive wheel 27 is mounted on the drive shaft of the adjusting motor 26. A matching linkage belt 28 is fitted between the drive wheel 27 and the driven wheel 24.

[0024] The worktable 1 is provided with a pair of slide rails 12, and the adjusting screw sleeve 23 is slidably installed on the corresponding slide rail. The slide rails are arranged parallel to the adjusting screw.

[0025] Before using this device to transport circuit boards, the width of the left and right belt conveyors can be adjusted according to the size of the circuit board. When it is necessary to adjust the width of the left and right belt conveyors to accommodate circuit boards of different sizes, start the adjusting motor to drive the drive wheel to rotate. The drive wheel drives the driven wheel to rotate via the linkage belt, which in turn causes the adjusting screw to rotate. Because the adjusting screw has a reverse thread section and the adjusting sleeve is slidably mounted on the slide rail, the rotation of the adjusting screw will cause the two adjusting sleeves to move towards or away from each other along the slide rail, thereby driving the two belt conveyors to move and achieving the adjustment of the conveying width. This adjustment method is simple to operate, has high adjustment accuracy, and can quickly adapt to the conveying needs of circuit boards of different sizes.

[0026] In this structure, such as Figure 2 , Figure 4 The workbench 1 is also equipped with a blocking mechanism, which includes a lifting plate 13. A blocking plate 14 is provided on the lifting plate 13 in front of the pressure plate 51. Lifting screw sleeves 15 are provided at the four corners of the lifting plate 13. Lifting screw rods 16 are inserted downward in each lifting screw sleeve 15. The lifting screw rods 16 pass through the workbench 1 below and are provided with pulleys 17. A drive wheel (covered in the figure) is also provided on the bottom surface of the workbench 1. The drive wheel and the pulley 17 are fitted with matching drive belts 19. A drive motor 20 for driving the drive wheel to rotate is also provided on the bottom surface of the workbench 1.

[0027] Once the previous circuit board is transported to the processing station, the blocking mechanism can block subsequent circuit boards. During circuit board transport, when it is necessary to block a circuit board from moving forward, the drive motor is started, causing the drive wheel to rotate. The drive wheel, through the drive belt, drives all the pulleys to rotate simultaneously, which in turn causes the lifting screw to rotate. Under the action of the lifting screw, the lifting plate rises, and the blocking plate rises accordingly, blocking subsequent circuit boards. When it is necessary to release the circuit board, the drive motor rotates in the opposite direction, causing the blocking plate to descend, allowing the circuit board to continue transporting.

[0028] In addition, as shown in the figure, multiple abutment wheels 250 are provided on the motor base 25 and the bottom surface of the worktable 1 respectively, corresponding to the rotation of the linkage belt and the drive belt. The abutment wheels abut against the linkage belt and the drive belt, making the linkage belt and the drive belt more stable during transmission.

[0029] 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.
