Abstract
Description
Technical Field
[0001] This utility model relates to the field of semiconductor element cutting technology, and specifically to a semiconductor element cutting device with a protective structure. Background Technology
[0002] During the production process, semiconductor components need to go through processes such as packaging, photolithography, and lead cutting. When semiconductor components are led, lead cutting equipment is used to cut the leads of the semiconductor components, cutting the strip-shaped semiconductor device into semiconductor particles.
[0003] During the manufacturing of strip semiconductor components, circular holes are often simultaneously drilled in the portion of the leads to be cut off to facilitate subsequent lead cutting operations. When the cutting equipment cuts the component leads, the circular holes on the leads are fitted onto the protrusions of the placement stage to limit the component to be cut. However, after cutting, the circular holes on the cut-off portion of the leads are still fitted onto the protrusions, making it inconvenient to clean up the waste material after lead cutting, resulting in low efficiency of the entire lead cutting operation.

[0007] To achieve the above objectives, this utility model provides the following technical solution:
[0008] In this utility model, a semiconductor element cutting device with a protective structure is used for cutting the workpiece to be cut. It includes a placement stage, on which a pin placement area is provided, and a limit structure is provided on the pin placement area.
[0009] The limiting structure includes multiple equally spaced slots, and each slot contains two symmetrically arranged arc-shaped inserts.
[0010] After the curved insert is inserted into the slot, the height of the curved insert is higher than the surface of the placement table.

[0013] Furthermore, each slot and the cylinder formed by the placement platform are provided with multiple grooves, and the arc-shaped insert plate is provided with a protrusion that matches the groove on the side near the cylinder.

[0015] Furthermore, the placement platform is mounted on the machine body, and a driving component is also mounted on the machine body. A cutting table is mounted on one end of the driving component near the placement platform. The cutting table is driven by a cylinder to approach the pin placement area and cut the pin to be cut on the pin placement area.
[0016] The machine body is equipped with a limiting component, and the driving component is slidably connected to the sliding groove on the limiting component via a slider. The driving component is driven to move closer to or away from the placement platform by a second cylinder.

[0022] (III) Beneficial Effects
[0023] This invention provides a semiconductor device lead cutting device with a protective structure. Compared with the prior art, it has the following advantages:
[0024] By setting a limiting structure, the pin portion of the workpiece to be cut is limited, improving the stability of the cutting equipment when cutting the pin portion.

[0034] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0035] This application provides a semiconductor element lead-cutting device with a protective structure, which solves the problem in the prior art that the circular hole on the cut-off part of the lead is still fitted on the protrusion, thereby improving the lead-cutting efficiency of semiconductor elements.
[0036] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.
[0037] like Figure 1-Figure 2 as well as Figure 4 As shown, a semiconductor element cutting device with a protective structure is used for cutting the workpiece 3 to be cut. It includes a placement stage 1, on which a pin placement area 11 is provided, and a limit structure is provided on the pin placement area 11.
[0038] The limiting structure includes multiple equally spaced slots, and each slot is equipped with two symmetrically arranged arc-shaped inserts 13.
[0039] After the arc-shaped insert 13 is inserted into the slot, the height of the arc-shaped insert 13 is higher than the surface of the placement platform 1.
[0040] A cutting groove is formed between two arc-shaped inserts 13 located in the same slot, which is parallel to the length direction of the pin of the workpiece 3 to be cut.
[0041] By setting a limiting structure, the pin portion of the workpiece 3 to be cut is limited, thereby improving the stability of the cutting equipment when cutting the pin portion of the workpiece 3. At the same time, the limiting structure is set in the form of two arc-shaped inserts 13, and a cutting groove is formed between the two corresponding arc-shaped inserts 13. This allows the limiting structure to limit the pin portion while also enabling the cut-off pin portion to detach from the limiting structure. This solves the problem in the prior art where, after cutting, the round hole on the cut-off pin portion is still fitted onto the protrusion, making it inconvenient to clean up the waste material after cutting, resulting in low efficiency of the entire cutting operation.
[0042] like Figure 1-Figure 2 As shown, each of the arc-shaped inserts 13 is detachably connected to the placement platform 1;
[0043] Specifically, the arc-shaped insert 13 is inserted into the placement platform 1 through a slot. By setting the arc-shaped insert 13 to be inserted into the placement platform 1, it is easy to replace the arc-shaped insert 13.
[0044] like Figure 2 As shown, each slot and the cylinder 12 formed by the placement platform 1 are provided with multiple grooves 121, and the arc-shaped insert plate 13 is provided with a protrusion 131 that matches the groove 121 on the side near the cylinder 12.
[0045] When each arc-shaped insert plate 13 is inserted into the slot, the multiple protrusions 131 on each arc-shaped insert plate 13 are inserted into the corresponding grooves 121 one by one.
[0046] By setting the groove 121 and the protrusion 131, the stability of the arc-shaped insert plate 13 when it is inserted into the placement platform 1 can be further improved, thereby improving the stability of the limiting structure in limiting the pin part of the workpiece 3 to be cut.
[0047] like Figure 3 As shown, the placement platform 1 is mounted on the machine body 2, and the machine body 2 is also mounted on the drive component 21. A cutting table 27 is mounted on one end of the drive component 21 near the placement platform 1. The cutting table 27 is driven by a cylinder to approach the pin placement area 11 and cut the pin placement area 11 to be cut.
[0048] The body 2 is equipped with a limiting component 20, and the driving component 21 is slidably connected to the sliding groove on the limiting component 20 through a slider. The driving component 21 is driven to move closer to or away from the placement platform 1 by a cylinder 2.
[0049] The drive unit 21 is equipped with a plurality of limiting posts 22 at one end near the placement platform 1, and the placement platform 1 is provided with limiting holes 10 corresponding to the limiting posts 22 one by one.
[0050] By setting the limiting post 22 and the limiting hole 10, the stability of the rebar cutting equipment during cutting can be improved.
[0051] like Figure 3 As shown, a support plate 23 is fixedly connected to the limiting member 20;
[0052] The support plate 23 is equipped with a protective structure at one end near the placement platform 1. The protective structure includes a first connecting rod 24, a second connecting rod 25, a connecting block 26, and a swing rod 261.
[0053] The first connecting rod 24 and the second connecting rod 25 are movably connected by a second rotating shaft 242. The end of the first connecting rod 24 away from the second connecting rod 25 is rotatably connected to the driving member 21 through a first rotating shaft 241. A third rotating shaft 251 is rotatably connected to the support plate 23. The end of the second connecting rod 25 away from the first connecting rod 24 is fixedly sleeved on the third rotating shaft 251. The swing rod 261 is fixedly sleeved on the third rotating shaft 251 through a connecting block 26. The swing rod 261 is rotatably connected to the support plate 23 through the third rotating shaft 251.
[0054] When the driving component 21 moves away from or near the placement platform 1, the swing arm 261 swings to the left or right around the pivot 251.
[0055] By setting up a protective structure, when the rebar cutting equipment cuts the workpiece 3, the swing arm 261 swings in one direction, which can give the staff a warning that the equipment is running. At the same time, the swing arm 261 can effectively prevent the risk of the operator's hand being accidentally placed on the placement table 1 during the operation of the equipment.
[0056] During the work, manual handling is required. Figure 4 The circular holes on the pin portion of the workpiece 3 to be cut are fitted one by one onto the limiting structure on the placement platform 1, and the pin portion is limited by two symmetrically arranged arc-shaped inserts 13 in two slots.
[0057] The strip semiconductor element to be cut 3 is placed in the corresponding position of the pin placement area 11. After the cutting element 3 is placed, the driving component on the cutting device is started. The driving component 21 is driven by the cylinder to move closer to the placement stage 1. The limiting post 22 on the driving component 21 is gradually inserted into the corresponding limiting hole 10 on the placement stage 1.
[0058] As the limiting post 22 on the driving component 21 gradually inserts into the corresponding limiting hole 10 on the placement table 1, and the limiting post 22 continues to slide along the limiting hole 10, at the same time, the cylinder 2 on the cutting table 27 drives the cutting table 27 to cut the workpiece 3 on the placement table 1. Figure 4 The dotted line represents the part that is cut off. During cutting, the cutting blade on the cutting table 27 cuts along the three vertical dotted lines, and the swing arm 261 swings to the right in the forward direction without interfering with other parts of the body 2.
[0059] After the cutting is completed, the waste area after the pin cutting breaks along the center of the dotted line, and the waste area is separated from the limiting structure, realizing the entire pin cutting process on the semiconductor device.
[0060] In summary, compared with existing technologies, it has the following beneficial effects:
[0061] 1. By setting a limiting structure, the pin portion of the workpiece 3 to be cut is limited, which improves the stability of the cutting equipment when cutting the pin portion of the workpiece 3. At the same time, the limiting structure is set in the form of two arc-shaped inserts 13, and a cutting groove is formed between the two corresponding arc-shaped inserts 13. This allows the limiting structure to limit the pin portion while also allowing the cut-off pin portion to detach from the limiting structure. This solves the problem in the prior art that after cutting, the round hole on the cut-off pin portion is still fitted on the protrusion, which is inconvenient for subsequent cleaning of the waste material after cutting, resulting in low efficiency of the entire cutting operation.
[0062] 2. By setting the groove 121 and the protrusion 131, the stability of the arc-shaped insert plate 13 when it is inserted into the placement platform 1 can be further improved, thereby improving the stability of the limiting structure in limiting the pin part of the workpiece 3 to be cut.
[0063] 3. By setting up a protective structure, when the rebar cutting equipment cuts the workpiece 3, the swing arm 261 swings in one direction, which can give the staff a warning that the equipment is running. At the same time, the swing arm 261 can effectively prevent the risk of the operator's hand being accidentally placed on the placement table 1 during the operation of the equipment.
