Description

Technical Field

[0001] This utility model relates to the field of lead-cutting devices, and in particular to a lead-cutting device for the production of electronic control boards. Background Technology

[0002] An electronic control board is made by soldering electronic components onto a PCB board. The PCB board and electronic components are used to form the designed electronic control board circuit to complete the work of an electronic circuit. The control board is also a type of circuit board. Although its application range is not as wide as that of a circuit board, it is more intelligent and automated than a regular circuit board. During the production process, electronic components are soldered onto the control board. The pins at the bottom of the control board pass through holes in the electronic control board and are exposed to the outside. The pins need to be cut off by a corner-cutting device to keep the electronic control board flat.

[0003] Existing lead-cutting devices require manual cutting during installation and use, resulting in low work efficiency. Some lead-cutting devices require stopping the equipment after cutting the lead, and then having workers clamp and disassemble the electronic control board, leading to low work efficiency and causing certain adverse effects on the user experience. In order to overcome the shortcomings of the existing technology, we propose a lead-cutting device for electronic control board production. Utility Model Content

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Example 1, as Figures 1-4As shown, a lead-cutting device for electronic control board production includes a workbench 1. A mounting base 3 is provided on the upper outer surface of the workbench 1. The operator slides the T-shaped block at the bottom of the base plate 5 into a groove in the inner wall of the mounting base 3. The base plate 5 is then fixed to the mounting base 3 using fixing screws, facilitating the installation and removal of the fixing clamp 6. This allows for quick clamping of electronic control boards by changing the fixing clamp 6 to different specifications. Multiple sets of first cylinders 8 and push plates 9 are provided. When the shearing groove 17 is cutting the lead of one set of electronic control boards, the operator can clamp the electronic control board between another set of push plates 9 and the positioning groove 7. The first cylinders 8 push the push plates 9 to fix the board. After the shearing groove 17 has finished cutting the lead of one set of electronic control boards, the first motor 4 controls the lead screw 25 to rotate, moving the shearing groove 17 above another assembled and clamped electronic control board for further cutting. The operator then removes the cut electronic control board and continues clamping, thereby improving work efficiency.

[0022] Example 2, as Figures 1-4 As shown, a lead-cutting device for electronic control board production, when the equipment cuts the lead of the electronic control board, controls the transmission rod 14 to rotate through the second motor 12, and controls the sliding block 13 to slide inside the transverse groove 11. At the same time, it works in conjunction with the first motor 4 and the lead screw 25 to cut the lead at different positions. By controlling the extension and retraction length of the second cylinder 16, the height of the lead can be easily adjusted by the operator. When the cutting groove 17 covers the outside of the reserved metal lead, the first electric push rod 20 and the second electric push rod 21 push the cutting rod 22 and the cutting blade 24 to move relative to each other, cutting the reserved metal lead. The operator connects an external vacuum cleaner to the cutting groove 17 through the connection port 19 with a hose. When the vacuum cleaner is working, it creates a negative pressure inside the cutting groove 17 and the hose, thereby sucking up the cut metal lead and preventing it from accumulating inside the cutting groove 17 and affecting the cutting quality.

[0023] It should be noted that this utility model is a cutting device for the production of electronic control boards. In use, the operator first slides the T-shaped block at the bottom of the base plate 5 into the groove on the inner wall of the mounting base 3, and fixes the base plate 5 above the mounting base 3 with fixing screws. This makes it convenient for the operator to change the fixing clamps 6 of different specifications to quickly clamp the electronic control board. Then, the horizontal groove 11 is fixed above the two sets of support plates 10, the second motor 12 is fixed at the rear end of the horizontal groove 11, and the rear end of the transmission rod 14 is passed through the inner wall of the horizontal groove 11 and connected to the output end of the second motor 12. The cutting groove 17 is connected to the lower end of the second cylinder 16. The second cylinder 16 limits the cutting groove 17 to the lower part of the sliding block 13. The first motor 4 and the lead screw 25 work together with the second motor 12 and the transmission rod 14 to make it convenient for the operator to cut the feet at different positions on the electronic control board. The blade holder 23 makes it convenient for the operator to clamp and replace the cutting blade 24.

[0024] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
