Description

Technical Field

[0001] The utility model relates to the technical field of PCB circuit board processing, in particular to an automatic edge-breaking device for PCB circuit boards. Background Art

[0002] A PCB circuit board generally refers to a circuit board, which miniaturizes and visualizes the circuit and plays an important role in the mass production of fixed circuits and the optimization of electrical appliance layouts. The circuit board can be called a printed circuit board or a printed wiring board, and its English name is (Printed Circuit Board) PCB, (Flexible Printed Circuit board) FPC circuit board (the FPC circuit board is also called a flexible circuit board. The flexible circuit board is a printed circuit board made of polyimide or polyester film as the base material, which has high reliability and excellent flexibility. It has the characteristics of high wiring density, light weight, thin thickness and good bendability.) and a rigid-flexible combination board (reechas, Soft and hard combination plate) - the birth and development of FPC and PCB have given birth to this new product of rigid-flexible combination board. Nowadays, in order to meet the requirements of plugging components and wave soldering during the production process, process edges need to be set on both sides of the PCB board. After all processes are completed, the process edges need to be broken off. At present, the method of using tools plus manpower or simple tooling plus manpower is mostly adopted. The work of workers is relatively heavy, and the error rate is relatively high, and the production efficiency is relatively low. At the same time, when using the manual breaking-off method, it is easy to produce burrs on both sides of the pcb board, resulting in a secondary edge-trimming step, which in turn affects the production efficiency. Therefore, we propose an automatic edge-breaking device for PCB circuit boards. Content of the Utility Model

Specific embodiments

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Embodiment, please refer to Figures 1-4 , the present utility model provides a technical solution:

[0023] An automatic edge-breaking device for PCB circuit boards, including a fixed bottom plate 1, characterized in that: fixing screws 2 are arranged around the top surface of the fixed bottom plate 1, a vertical plate 3 is fixedly connected to the top surface of the fixed bottom plate 1, a cylinder 4 is fixedly connected to the side surface of the vertical plate 3, a support column 6 is fixedly connected to the top surface of the fixed bottom plate 1, a fixed plate 7 is fixedly connected to the top surface of the support column 6, a first chute 8 is opened in the fixed plate 7, an I-shaped slider 9 is arranged in the first chute 8, a clamping plate 10 is fixedly connected to the top surface of the I-shaped slider 9, and a pcb combination board 11 is arranged on the side surface of the clamping plate 10.

[0024] In this embodiment, as Figure 1 and Figure 2As shown in the figure, a vertical rod 12 is fixedly connected to the top surface of the fixed base plate 1. The bottom end of the vertical rod 12 is fixedly connected to a hydraulic lift 13. The bottom of the hydraulic lift 13 is fixedly connected to a support plate 14. A second chute 15 is formed inside the support plate 14. A cutting knife 18 is arranged inside the second chute 15. A clamping member 16 is arranged on the top of the cutting knife 18. A fastening screw 17 is arranged on the top surface of the clamping member 16. A push rod 20 is fixedly connected to the side of the cutting knife 18. A master controller 5 is fixedly connected to the top surface of the fixed base plate 1. The master controller 5 is electrically connected to both the hydraulic lift 13 and the cylinder 4. There are two second chutes 15, and clamping grooves 19 are formed on both sides of the second chutes 15.

[0025] Among them, pushing the push rod 20 can adjust the relative positions of the two cutting knives 18 so that they are directly above the position where the pcb composite board 11 needs to be broken. Then, the hydraulic lift 13 presses down to cut and separate the pcb composite board 11 with the cutting knives 18, thus avoiding the burrs generated by manual breaking. At the same time, the adjustable cutting knives 18 can separate different combinations of pcb composite boards 11, greatly improving the work efficiency. When the cutting knives 18 are worn after long-term work, the cutting knives 18 can be disassembled and replaced by rotating the fastening screws 17.

[0026] In this embodiment, as Figure 3 and Figure 4 shown, the length of the clamping groove 19 is the same as that of the second chute 15. The fastening screws 17 all pass through the clamping member 16 and are in threaded connection with the cutting knife 18. There are two groups of cutting knives 18, and two clamping members 16 are arranged on the top of each group of cutting knives 18. There are two cylinders 4, and the output ends of the two cylinders 4 are fixedly connected to the I-shaped sliders 9. There are two first chutes 8, and I-shaped sliders 9 and clamping plates 10 are arranged inside the two first chutes 8. The I-shaped sliders 9 and the fixed base plate 1 are on the same horizontal plane. The fixed base plate 1 is made of stainless steel.

[0027] Among them, the telescoping of the cylinder 4 can drive the I-shaped slider 9 to move forward or backward, so as to fix different models of pcb composite boards 11, which is convenient for subsequent cutting and separation and improves the adaptability of the device.

[0028] Working process of the utility model: When a PCB circuit board automatic edge-breaking device designed by this solution is working, first fix the device on the workbench through the fixing screw 2, then place the pcb composite board 11 to be edge-broken on the surface of the fixing plate 7, and then control the cylinder 4 to move forward through the master controller 5. At this time, the clamping plate 10 slowly advances under the drive of the I-shaped slider 9 until it abuts against the pcb composite board 11, completing the fixation of the pcb composite board 11. Then, by pushing the push rod 20, the relative position of the two cutting knives 18 can be adjusted so that they are directly above the position where the pcb composite board 11 needs to be broken. Then, the hydraulic lift 13 presses down to cut and separate the pcb composite board 11 with the cutting knives 18, and the separation of the pcb composite board 11 can be completed.

[0029] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
