Abstract
Description
Technical Field
[0001] This utility model relates to the field of circuit board processing technology, and in particular to an adjustable circuit board lead trimming machine. Background Technology
[0002] A printed circuit board (PCB) is a core component of electronic devices, used to achieve electrical connections and mechanical fixation between electronic components. As an important carrier of the modern electronics industry, PCBs combine various electronic components (such as chips, resistors, capacitors, etc.) into complete circuit systems by printing conductive lines on their surface.
[0003] During the manufacturing process of existing circuit boards, electrical components need to be soldered onto the circuit board. After the soldering is completed, many leads will extend from the soldering surface of the circuit board. These leads may come into contact with other leads or external objects during use, causing the circuit board to short circuit. They usually need to be cut off.
[0004] Existing cutting machines typically hold the circuit board with the lead side facing up, clamp it with a fixture, and then cut it. This method requires adjusting the clamping tool after cutting one circuit board, and can only cut one circuit board at a time. This results in a lot of repetitive loading and unloading work, reducing work efficiency. Utility Model Content
[0005] Therefore, it is necessary to address the issue that cutting machines typically hold the circuit board with the lead side facing up, clamp it with a fixture, and then cut it with the cutting machine. This method requires adjusting the clamping tool after cutting one circuit board, and can only cut one circuit board at a time, resulting in a lot of repetitive loading and unloading work and reduced work efficiency. Therefore, it is necessary to provide an adjustable circuit board lead cutting machine.
[0006] This utility model achieves the above-mentioned objective through the following technical solution: an adjustable circuit board lead cutting machine, comprising: a worktable, with lead cutting machine bodies provided on both sides of the worktable, and the processing direction of the two lead cutting machine bodies being above the worktable;
[0007] The guide rail is located above the worktable and below the two shearing machine bodies, and the guide rail is divided into two guide tracks;
[0008] The circuit board body is provided in multiple ways, and all of the circuit board bodies slide inside the guide rail.
[0009] A drive assembly, which is located on the worktable and on one side of the guide rail, is used to push the circuit board body.
[0010] In one embodiment, the surface of the worktable has two guide grooves, which are respectively located below the two guide rails of the guide rail.
[0011] In one embodiment, the guide rail is provided with multiple sets of guide rollers, which are respectively located on both sides of the circuit board body.
[0012] In one embodiment, two feed slots are provided above the guide rail, and the two feed slots are respectively located on one side of the drive assembly.
[0013] In one embodiment, the drive assembly includes two toothed plates that slide on one side of the guide rail, a bidirectional motor is provided above the worktable, and a rotating shaft is driven and connected to the output ends on both sides of the bidirectional motor. Multiple gears are fixedly sleeved on the surface of the rotating shaft, and the lower parts of the multiple gears are respectively meshed with the two toothed plates.
[0014] In one embodiment, the plurality of gears rotate on one side of the guide rail, and the two sides of the gear plate slide inside the guide rail.
[0015] In one embodiment, two extension plates are fixedly connected to one side of the workbench, and the two extension plates are respectively located below the two toothed plates.
[0016] Beneficial effects
[0017] 1. The guide rail installed above the workbench is used to limit and guide the circuit board body; the drive component reciprocates to push the circuit board body in sequence inside the guide rail. Multiple circuit boards will slide under the shearing machine body in sequence. The shearing machine body and the drive component are controlled synchronously by the controller, which can smoothly move the circuit board body, reduce the disassembly and installation process of the circuit board body, greatly reduce the loading and unloading time of the circuit board body, and increase the shearing efficiency.
[0018] 2. The feed trough facilitates the placement of the circuit board body into the guide rail. When the circuit board body slides inside the guide rail, both sides of the circuit board body will contact multiple guide rollers. The multiple guide rollers reduce the friction between the inner wall of the guide rail and the circuit board body, making the sliding of the circuit board body smoother and improving the conveying efficiency of the circuit board body.

[0030] The following is combined with Figures 1-4 This invention describes an adjustable circuit board lead trimming machine.
[0031] In one embodiment, an adjustable circuit board lead trimming machine includes: a worktable 100, a guide rail 300, a circuit board body 400, and a drive assembly 500. Lead trimming machine bodies 200 are provided on both sides of the worktable 100, and the processing direction of the two lead trimming machine bodies 200 is above the worktable 100. The guide rail 300 is located above the worktable 100 and below the two lead trimming machine bodies 200. The guide rail 300 is divided into two guide rails. Multiple circuit board bodies 400 are provided, and the multiple circuit board bodies 400 slide inside the guide rail 300. The drive assembly 500 is provided on the worktable 100 and located on one side of the guide rail 300 for pushing the circuit board bodies 400.
[0032] The workbench 100 is placed horizontally, and the workbench 100 is supported by the shearing machine body 200 on both sides. The shearing machine body 200 is electrically driven and driven by hydraulic rods, pneumatic clamps and other equipment to perform repeated shearing actions according to the designed program.
[0033] Multiple circuit board bodies 400 are placed with their components facing down and their leads facing up into the guide rail 300. A drive component 500 on one side of the guide rail 300 pushes the circuit board bodies 400 out, causing them to slide inside the guide rail 300. The drive component 500 reciprocates. When the drive component 500 resets, the next circuit board body 400 is placed into the guide rail 300. The drive component 500 pushes the multiple circuit board bodies 400 to move. The multiple circuit board bodies 400 move sequentially from under the two lead-cutting machine bodies 200. The lead-cutting machine bodies 200 cut the leads on the circuit board bodies 400. By having the multiple circuit board bodies 400 slide inside the guide rail 300, the time spent repeatedly fixing and removing the circuit board bodies 400 is reduced, greatly increasing the cutting efficiency of the lead-cutting machine bodies 200.
[0034] like Figure 1 , Figure 2 and Figure 3 As shown, the surface of the worktable 100 has two guide grooves 101, which are located below the two guide rails of the guide rail 300 respectively.
[0035] The guide groove 101 extends downward from the horizontal surface of the worktable 100. When the circuit board body 400 slides inside the guide rail 300, the electrical components of the circuit board body 400 will slide inside the guide groove 101, and the guide groove 101 increases the activity space inside the guide rail 300.
[0036] like Figure 2 , Figure 3 and Figure 4 As shown, the guide rail 300 is provided with multiple sets of guide rollers 302, which are located on both sides of the circuit board body 400. Two feed slots 301 are opened on the top of the guide rail 300, and the two feed slots 301 are located on one side of the drive assembly 500.
[0037] When the circuit board body 400 slides inside the guide rail 300, the two sides of the circuit board body 400 will contact multiple guide rollers 302. The multiple guide rollers 302 reduce the friction between the inner wall of the guide rail 300 and the circuit board body 400, making the sliding of the circuit board body 400 smoother. The feed groove 301 makes it convenient to put the circuit board body 400 into the interior of the guide rail 300.
[0038] like Figure 1 , Figure 2 and Figure 3As shown, the drive assembly 500 includes two toothed plates 504 that slide on one side of the guide rail 300. A bidirectional motor 501 is provided above the worktable 100. The output ends of the bidirectional motor 501 are driven and connected to the rotating shaft 502. Multiple gears 503 are fixedly sleeved on the surface of the rotating shaft 502. The lower parts of the multiple gears 503 are respectively meshed with the two toothed plates 504.
[0039] The two output ends of the bidirectional motor 501 rotate synchronously to drive the rotating shaft 502 to rotate. The rotating shaft 502 drives the multiple gears 503 sleeved on the surface to rotate. The rotation of the multiple gears 503 drives the toothed plate 504 to move. One side of the toothed plate 504 is inserted into the interior of the guide rail 300 and fits against one side of the circuit board body 400, driving the circuit board body 400 to move. The bidirectional motor 501 is electrically connected to the shearing machine body 200 and is synchronously controlled by the controller.
[0040] like Figure 1 , Figure 2 and Figure 3 As shown, multiple gears 503 rotate on one side of the guide rail 300, and the two sides of the toothed plate 504 slide inside the guide rail 300. Two extension plates 102 are fixedly connected to one side of the worktable 100, and the two extension plates 102 are located below the two toothed plates 504 respectively.
[0041] The toothed block of the toothed plate 504 is located above the internal groove of the guide rail 300. The groove of the extension plate 102 is connected to the guide rail 300. When one side of the toothed plate 504 slides inside the guide rail 300, the extension plate 102 will support and limit the toothed plate 504 above, increasing the stability of the toothed plate 504 and improving its stability.
[0042] Working principle: The guide rail 300 installed above the worktable 100 is used to limit and guide the circuit board body 400; the drive component 500 reciprocates to push the circuit board body 400 sequentially inside the guide rail 300. Multiple circuit board bodies 400 will slide under the shearing machine body 200 in sequence. The shearing machine body 200 and the drive component 500 are synchronously controlled by the controller, which can smoothly move the circuit board body 400, reduce the disassembly and installation process of the circuit board body 400, greatly reduce the loading and unloading time of the circuit board body 400, and increase the shearing efficiency.
[0043] It should be noted that the motors inside the shearing machine body 200 and drive assembly 500 mentioned above are all components with relatively mature existing technology. The specific models can be selected according to actual needs. At the same time, the shearing machine body 200 can be powered by the built-in power supply or by the mains power. The specific power supply method can be selected according to the situation, which will not be elaborated here.
[0044] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0045] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
