Description

Technical Field

[0001] This utility model relates to the field of vertical insertion machine technology, specifically to a suction device for scrap iron filings from the shearing unit of a vertical insertion machine. Background Technology

[0002] In the current Panasonic RL132 vertical component insertion machine, during the component insertion process, the conveyor unit delivers the component to the clamping jaws of the machine head unit. After the clamping jaws securely hold the component leads, the machine table moves to the insertion position according to the programmed coordinates. The head unit then descends above the PCB board of the worktable, aligning the component leads with the insertion holes on the PCB board. The shearing unit rises, and the shearing blades cut and bend the component leads, completing one insertion and shearing operation. Each insertion and shearing operation generates scrap metal chips. These scrap metal chips are drawn into a waste metal chip bottle through a vacuum pump suction device via a chip suction funnel below the shearing unit, a chip suction pipe, and another chip suction funnel. The above-mentioned existing technology has the following main drawbacks: 1. In the process of the vacuum pump suction device drawing scrap iron filings into the scrap iron filings bottle, the material must pass through a suction funnel, a suction pipe, another suction funnel, and finally into the scrap iron filings bottle. The design and installation angle of the suction funnel and suction pipe can easily cause scrap iron filings to get stuck in the suction pipe or suction funnel unit, leading to blockages, machine shutdowns, and spare parts malfunctions. This also increases maintenance time and costs, severely impacting efficiency.

[0003] 2. The two chip collection funnels are designed with a 90-degree bend. One is installed on the unit support under the shear foot, and the other is installed on the scrap metal bottle. The two ends of the chip collection pipe connect to the chip collection funnel on the unit support under the shear foot and the chip collection funnel in the scrap metal bottle, respectively, at an angle of approximately 45 degrees. Due to the design of the chip collection funnels and the installation position of the chip collection pipe, scrap metal easily gets stuck at the 90-degree bend of the chip collection funnel and in the chip collection pipe. This leads to equipment shutdown due to blockage alarms in the lower unit and abnormal shear foot operation.

[0004] 3. The waste metal scrap bottle has too small a capacity, and it must be emptied twice during each shift of production. Because employees are busy with many tasks during operation, they may easily overlook emptying the scrap metal scrap, causing the waste metal scrap bottle to become clogged, affecting downtime and production efficiency.

[0005] 4. During the process of vacuum pumping chips, the chip suction funnel bends, which affect the suction force and are prone to clogging. If the waste bottle is blocked, the vacuum pump will continue to work, which will also cause abnormal damage to the vacuum pump carbon plates, increase maintenance costs and downtime, and affect efficiency. Summary of the Invention

[0006] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a suction device for scrap iron chips from the cutting unit of a vertical insert machine.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: The vertical insert machine's scrap metal suction device for the shearing unit includes an upper connecting pipe, a lower connecting pipe, a scrap collection box, and a vacuum generator; The vacuum generator is attached and fixed to the outside of the upper connecting pipe. The vacuum generator is used to create a vacuum inside the upper connecting pipe to generate suction. The connecting frame to which the vacuum generator is fixed is fixed to the mounting frame below the scissor unit. The upper end of the upper connecting pipe is sleeved on the outside of the chip suction pipe of the shearing unit, the lower end of the upper connecting pipe is sleeved on the inside of the upper end of the lower connecting pipe, and the lower end of the lower connecting pipe is fixedly connected to the top of the waste collection box to discharge the scrap iron filings into the waste collection box. The upper connecting pipe, lower connecting pipe, and the chip suction pipe of the shearing unit are coaxial and all arranged in a vertical direction.

[0008] Furthermore, the waste collection box includes an outer box and an inner box. The inner box is movably pulled out and connected to the outer box. The top surface of the inner end of the inner box is open, which is located directly below the lower end of the lower connecting pipe. Waste iron filings enter the inner box through this opening.

[0009] Furthermore, the outer end of the inner box is provided with a handle.

[0010] Furthermore, the connecting bracket to which the vacuum generator is fixedly connected is bolted to the mounting bracket below the scissor unit.

[0011] Furthermore, the waste collection box is equipped with a sensor to detect the amount of iron filings collected inside the waste collection box.

[0012] By adopting the above technical solution, the beneficial effects of this utility model are as follows: The core improvement of this invention lies in transforming the traditional, complex chip-collecting path with multiple bends into a coaxial vertical channel composed of an upper connecting pipe, a lower connecting pipe, and a chip-collecting pipe for the shearing unit. The scrap iron chips fall freely under gravity, guided by the suction of a vacuum generator, allowing them to fall smoothly and unobstructed directly into the waste collection box. This fundamentally eliminates the risk of iron chips getting stuck at bends, greatly reduces abnormal downtime caused by blockages, and significantly improves the overall production efficiency of the equipment.

[0013] 2. The upper and lower connecting pipes adopt an inner and outer sleeve assembly method, which allows for quick disassembly and assembly without the need for complicated tools, greatly facilitating daily inspection, cleaning, and maintenance of the pipeline. Meanwhile, the waste collection box features a split outer box and a pull-out inner box design. When it is necessary to clean iron filings, the operator can easily pull out the inner box using the handle, empty the filings, and push it back in. The operation is simple and quick, effectively reducing equipment maintenance time and labor costs. Attached Figure Description

[0014] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments: Figure 1 This is a front view of the overall structure of this utility model; Figure 2 This is a schematic diagram showing the connection between the upper connecting pipe and the vacuum generator; Figure 3 This is a schematic diagram showing the connection between the lower connecting pipe and the waste collection box. Figure 4 This is a schematic diagram of the inner box structure. Detailed Implementation

[0015] This utility model is a modification of the structure of the scrap metal suction device on the existing Panasonic RL132 vertical insert machine.

[0016] like Figure 1-4 As shown, this utility model includes a vacuum generator 1, a connecting frame 2, an upper connecting pipe 3, a lower connecting pipe 4, and a waste collection box 5.

[0017] The vacuum generator 1 is attached to the middle outer wall of the fixed connecting pipe 3. One end of the connecting bracket 2 is fixedly connected to the housing of the vacuum generator 1, and the other end is fixedly fastened to the mounting bracket 7 below the scissor unit 6 by bolts.

[0018] The upper end of the upper connecting pipe 3 is sleeved on the outside of the chip suction pipe 8 of the shearing unit 6 itself. The lower end of the upper connecting pipe 3 is inserted into the upper end of the lower connecting pipe 4. The upper connecting pipe 3, the lower connecting pipe 4, and the chip suction pipe 8 of the shearing unit 6 form a coaxial vertical channel. The waste collection box 5 is located at the bottom of the entire device, and its top is fixedly connected to the lower end of the lower connecting pipe 4. The scrap iron filings can fall freely under the action of gravity, and at the same time, with the suction guidance of the vacuum generator 1, the scrap iron filings can fall smoothly and unobstructed directly into the waste collection box 5.

[0019] The waste collection box 5 preferably adopts a split design, including an outer box 51 fixed to the frame and a movable, pull-out inner box 52. The top surface of the inner end of the inner box 52 is an open opening 521, which faces the lower outlet of the lower connecting pipe 4 to ensure that scrap iron filings fall accurately into it. The outer end of the inner box 52 is provided with a handle 53 for easy pulling and cleaning by the operator. In addition, a sensor 9 is provided on the waste collection box 5 (preferably on the outer box 51) to detect the amount (pile height) of scrap iron filings collected in the inner box 52 in real time.

[0020] During the operation of the vertical insertion machine, the scrap iron filings generated by the shearing unit 6 fall into its scrap suction pipe 8. The vacuum generator 1 is activated, generating negative pressure inside the upper connecting pipe 3, which applies a downward suction force to guide the falling iron filings. The scrap iron filings then pass through the upper connecting pipe 3 and the lower connecting pipe 4 in sequence, and finally fall vertically into the inner box 52 of the waste collection box 5.

[0021] Because the pipe connection in this invention is a nested connection where the lower pipe is on the outside and the upper pipe is on the inside, no steps or protrusions form on the inner wall of the waste material flow channel. Under the influence of gravity and suction, the waste material falls directly into the lower pipe without obstruction. This structure fundamentally avoids the accumulation of iron filings and wall adhesion problems caused by internal steps in traditional pipe fitting connections, further improving the reliability of anti-clogging. The aforementioned nested structure is typically a clearance fit; when maintenance is required, both the upper connecting pipe 3 and the lower connecting pipe 4 can be independently disassembled for easy cleaning or replacement, making the operation very simple.

[0022] When sensor 9 detects that the amount of iron filings in the inner casing 52 has reached a preset capacity (e.g., 2 / 3 of the internal volume of the inner casing 52), it sends a signal to the equipment control system, triggering an audible and visual alarm and automatically stopping the equipment to remind the operator to clean it. This preventative maintenance mechanism, combined with the increased capacity of the inner casing 52, ensures production continuity and equipment safety.

[0023] The specific embodiments of this utility model have been described above. However, those skilled in the art should understand that this is only an example. Those skilled in the art can make various changes or modifications to this embodiment without departing from the principle and essence of this utility model, but all such changes and modifications fall within the protection scope of this utility model.
