Description

Technical Field

[0001] This utility model relates to the field of integrated circuit chip manufacturing technology, and in particular to a guide protection device for integrated circuit chip manufacturing. Background Technology

[0002] An integrated circuit chip is an electronic component comprising a silicon substrate, at least one circuit, a fixed sealing ring, a grounding ring, and at least one protective ring. The lead frame, as the chip carrier of the integrated circuit, is a key structural component that uses bonding wires to realize the electrical connection between the internal circuit leads of the chip and the external leads, forming an electrical circuit. It acts as a bridge connecting with external wires, and after production, the lead frame needs to be placed inside the lead frame storage box for protection.

[0003] A search revealed Chinese patent CN220873542U, which discloses a guiding and protective device for integrated circuit chip manufacturing. The device includes: a base with a groove on its top; a cover plate fixedly connected to the top of the base; an adjustment assembly inside the base; multiple placement slots on the outer side of the cover plate of the adjustment assembly; a connecting shaft fixedly connected to the adjustment assembly; the connecting shaft laterally passing through and rotatably connecting to the side wall of the base; and a rotating handle fixedly connected to one end of the connecting shaft outside the base. This guiding and protective device for integrated circuit chip manufacturing adjusts the distance between the placement slots by using the adjustment assembly. When the gear rotates counterclockwise, it moves the first and second connecting plates closer together via a slot; when the gear rotates clockwise, it moves the first and second connecting plates further apart via the slot.

[0004] The aforementioned integrated circuit chip manufacturing guide protection device has the following shortcomings: it lacks a mechanism to limit the rotation handle, and after adjusting the positions of the two connecting plates, it cannot guarantee the stability of the position between the two connecting plates. The two connecting plates may move away from each other, and the guide frame cannot be stably placed in the placement slot, posing a risk of falling off. Therefore, it is necessary to design a guide protection device for integrated circuit chip manufacturing to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a guidance and protection device for integrated circuit chip manufacturing.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A guiding and protective device for integrated circuit chip production includes a base. A circular plate is disposed on one side of the base, and the circular plate is rotatably connected to the base. The circular plate has several limiting grooves and a square groove. A drive shaft is disposed within the square groove. A handle is fixedly connected to one side of the drive shaft. A ring is fixedly connected to the outer wall of the handle. The handle and the ring are fitted with the same sleeve plate, which rotatably connects the handle and the ring. An L-shaped plate is fixedly connected to the outer wall of the sleeve plate. A fixed shaft is fixedly connected to one top side of the L-shaped plate. Rollers are fitted at both ends of the fixed shaft, and the rollers are rotatably connected to the fixed shaft. Two square plates are fitted with square plates. A first sliding groove is formed on the square plate, and the rollers are disposed within the first sliding groove. A lifting plate is fixedly connected to the bottom of the two square plates. A limiting block is fixedly connected to the bottom of the lowering plate. The limiting block is adapted to the limiting groove. Due to the technical means of limiting the angle of the circular plate by the cooperation of the limiting block and the limiting groove, the circular plate cannot rotate when the limiting block is in the limiting groove, and the handle cannot rotate either. This limits the position between the two connecting plates, so that the guide frame is stably placed in the placement groove. This effectively solves the problem proposed in the background technology that there is no mechanism to limit the rotation handle. After the position of the two connecting plates is adjusted, the position between the two connecting plates cannot be guaranteed to be stable. The two connecting plates may move away from each other, and the guide frame cannot be stably placed in the placement groove, which may lead to the risk of falling off. Thus, it achieves the technical effect of effectively ensuring the relative position stability between the two connecting plates, ensuring that the guide frame can be stably placed in the placement groove, and improving the reliability and safety of the structure.

[0008] Preferably, a first movable plate is fixedly connected to both sides of the lifting plate, a first guide rod is provided on the first movable plate, the first movable plate is slidably connected to the first guide rod, a fixed plate is fixedly connected to the top of the first guide rod, and both fixed plates are fixedly connected to one side of the base.

[0009] Preferably, a spring is provided on the top of the first movable plate, and the spring is sleeved on the first guide rod.

[0010] Preferably, the top of the base is provided with a cover plate, and the cover plate has four second sliding grooves.

[0011] Preferably, each of the four second sliding grooves is provided with a slider, the slider is slidably connected to the cover plate, the tops of the two sliders at the same end are fixedly connected to the same connecting plate, the connecting plate is provided with a plurality of placement grooves, and the connecting plate is provided with a buffer pad in the placement groove.

[0012] Preferably, the bottom of each of the four sliders is fixedly connected to a second movable plate, and the same second guide rod is passed through two second movable plates on the same side. The second movable plates are slidably connected to the second guide rod, and the second guide rod is fixedly connected to the inner wall of the base.

[0013] Preferably, the two second movable plates at the same end are fixedly connected to the same third movable plate on their adjacent sides. A lead screw nut passes through the third movable plate and is fixedly connected to it. The two lead screw nuts are connected to the same bidirectional lead screw, which is adapted to the bidirectional lead screw. Bearings are fitted at both ends of the bidirectional lead screw. The outer wall of the bearing is fixedly connected to the inner wall of the base, and the inner wall of the bearing is fixedly connected to the bidirectional lead screw. A first bevel gear is fixedly connected to the outer wall of the bidirectional lead screw. The first bevel gear meshes with a second bevel gear. A drive rod is fixedly connected to one side of the second bevel gear. The drive rod passes through the base and is rotatably connected to the base. The drive rod is fixedly connected to the side of the circular plate away from the handle.

[0014] The beneficial effects of this utility model are as follows:

[0015] By employing a combination of limiting blocks and limiting grooves to restrict the angle of the circular plate, the circular plate cannot rotate when the limiting block is within the limiting groove, and the handle cannot rotate either. This effectively restricts the position between the two connecting plates, ensuring the guide frame is stably positioned within the placement groove. This solves the problem in the background technology where the lack of a mechanism to limit the rotation handle meant that after adjusting the positions of the two connecting plates, their position could not be guaranteed to be stable, potentially causing them to drift apart and the guide frame to become unstable within the placement groove, posing a risk of detachment. Therefore, this technology effectively ensures the relative positional stability between the two connecting plates, guaranteeing the guide frame is securely positioned within the placement groove, thus improving the reliability and safety of the structure.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figure 1-6A guiding and protective device for integrated circuit chip production includes a base 1, a circular plate 2 on one side of the base 1, the circular plate 2 being rotatably connected to the base 1, a plurality of limiting grooves 3 on the circular plate 2, a square groove 4 on the circular plate 2, a drive shaft 5 disposed within the square groove 4, a handle 6 fixedly connected to one side of the drive shaft 5, a ring 7 fixedly connected to the outer wall of the handle 6, the handle 6 and the ring 7 being fitted with the same sleeve plate 8, the sleeve plate 8 rotatably connecting the handle 6 and the ring 7, an L-shaped plate 9 fixedly connected to the outer wall of the sleeve plate 8, a fixed shaft 10 fixedly connected to one top side of the L-shaped plate 9, rollers 11 fitted at both ends of the fixed shaft 10, the rollers 11 being rotatably connected to the fixed shaft 10, a square plate 12 fitted on each of the two rollers 11, a first sliding groove 13 on the square plate 12, the rollers 11 being disposed within the first sliding groove 13, and a common lifting mechanism fixedly connected to the bottom of the two square plates 12. Plate 14, the bottom of which is fixedly connected to a limiting block 15, which is adapted to the limiting groove 3. Due to the use of the limiting block and the limiting groove to limit the angle of the circular plate, when the limiting block is in the limiting groove, the circular plate cannot rotate, and the handle cannot rotate. This limits the position between the two connecting plates, so that the guide frame is stably placed in the placement groove. This effectively solves the problem in the background art that there is no mechanism to limit the rotation handle. After the position of the two connecting plates is adjusted, the position between the two connecting plates cannot be guaranteed to be stable. The two connecting plates may move away from each other, and the guide frame cannot be stably placed in the placement groove, which may lead to the risk of falling off. Thus, it effectively ensures the relative position stability between the two connecting plates, ensures that the guide frame can be stably placed in the placement groove, and improves the reliability and safety of the structure.

[0025] In this utility model, a first movable plate 16 is fixedly connected to both sides of the lifting plate 14. A first guide rod 17 is provided on the first movable plate 16. The first movable plate 16 is slidably connected to the first guide rod 17. A fixed plate 18 is fixedly connected to the top of the first guide rod 17. Both fixed plates 18 are fixedly connected to one side of the base 1. When the lifting plate 14 moves, it will drive the first movable plate 16 to move along the first guide rod 17, ensuring the stability of the lifting plate 14 when it moves.

[0026] In this utility model, a spring 19 is provided on the top of the first movable plate 16. The spring 19 is sleeved on the first guide rod 17. By providing the spring 19, when the spring 19 is extended, the limiting block 15 can be stably placed in the limiting groove 3 to restrict the circular plate 2 and prevent the circular plate 2 from rotating.

[0027] In this utility model, a cover plate 20 is provided on the top of the base 1, and four second sliding grooves 21 are provided on the cover plate 20.

[0028] In this utility model, each of the four second sliding grooves 21 is provided with a slider 22, the slider 22 is slidably connected to the cover plate 20, and the top of the two sliders 22 at the same end is fixedly connected to the same connecting plate 23. The connecting plate 23 is provided with a plurality of placement grooves 24, and the connecting plate 23 is provided with a buffer pad in the placement groove 24. When the lead frame is placed into the lead frame storage box, the distance between the two connecting plates 23 is adjusted according to the width of the lead frame, and the lead frame is placed into the placement groove 24.

[0029] In this utility model, the bottom of each of the four sliders 22 is fixedly connected to a second moving plate 25. The same second guide rod 26 is provided on the two second moving plates 25 on the same side. The second moving plate 25 is slidably connected to the second guide rod 26. The second guide rod 26 is fixedly connected to the inner wall of the base 1. When the second moving plate 25 moves, it will move along the second guide rod 26 to ensure the stability of the second moving plate 25 when it moves.

[0030] In this utility model, two second movable plates 25 at the same end are fixedly connected to the same third movable plate 27 on the side close to each other. A lead screw nut 28 is provided on the third movable plate 27, and the lead screw nut 28 is fixedly connected to the third movable plate 27. The two lead screw nuts 28 are provided with the same bidirectional lead screw 29, and the lead screw nut 28 and the bidirectional lead screw 29 are adapted to each other. Bearings 30 are sleeved on both ends of the bidirectional lead screw 29. The outer wall of the outer ring of the bearing 30 is fixedly connected to the inner wall of the base 1. The inner wall of the inner ring of the bearing 30 is fixedly connected to the bidirectional lead screw 29. A first bevel gear 31 is fixedly connected to the outer wall of the bidirectional lead screw 29. The first bevel gear 31 is meshed with a second bevel gear 32. A drive rod 33 is fixedly connected to one side of the second bevel gear 32. The drive rod 33 passes through the side of the base 1 and is rotatably connected to the base 1. The drive rod 33 is fixedly connected to the side of the circular plate 2 away from the handle 6.

[0031] Working principle: When the lead frame is placed in the placement slot 24, and the distance between the two connecting plates 23 needs to be adjusted according to the width of the lead frame, the handle 6 can be pulled to move it. Moving the handle 6 will drive the drive shaft 5 to move within the square slot 4. Moving the handle 6 will also drive the ring 7 to move, which in turn will drive the sleeve plate 8 to move. The sleeve plate 8 will drive the L-shaped plate 9 to move, which in turn will drive the fixed shaft 10 to move. The fixed shaft 10 will drive the roller 11 to move, which will then press against the square plate 12, causing the square plate 12 to move. Roller 11 moves within the first groove 13, pressing against the square plate 12 to raise it. The square plate 12 then lifts the lifting plate 14, which in turn lifts the limiting block 15, causing it to move out of the limiting groove 3, thus releasing the restriction on the circular plate 2. As the lifting plate 14 rises, it also lifts the first moving plate 16 along the first guide rod 17. The rising of the first moving plate 16 further compresses the spring 19, causing it to contract. After releasing the restriction on the circular plate 2, the handle 6 can be rotated, which in turn drives the drive shaft 5 to rotate. The moving shaft 5 drives the circular plate 2 to rotate, which in turn drives the drive rod 33 to rotate. The drive rod 33 then drives the second bevel gear 32 to rotate, which in turn drives the first bevel gear 31 to rotate. The first bevel gear 31 then drives the double-acting lead screw 29 to rotate, which in turn drives the lead screw nut 28 to move. The lead screw nut 28 then drives the third moving plate 27 to move, which in turn drives the second moving plate 25 to move along the second guide rod 26. The movement of the second moving plate 25 then drives the slider 22 to move. Block 22 will drive the connecting plate 23 to move, thereby adjusting the distance between the two connecting plates 23. After the adjustment is completed, push the handle 6 to make the roller 11 move again in the first slide groove 13, which will make the square plate 12 descend. The square plate 12 will drive the lifting plate 14 to descend, and the lifting plate 14 will drive the limiting block 15 to descend, so that the limiting block 15 will be locked into the limiting groove 3 again, thereby restricting the round plate 2 and preventing the round plate 2 from rotating and causing the position between the two connecting plates 23 to move unexpectedly, thus ensuring the stability of the position between the two connecting plates 23.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
