Description

Technical Field

[0001] This utility model relates to the field of clamping device technology, and in particular to a chip handling clamp. Background Technology

[0002] After the chips are manufactured, they need to be transferred. Manual transfer can easily result in sweaty hands getting on the chips. Therefore, a clamp is usually used to hold the chips before transfer.

[0003] For example, the patent with publication number CN217306479U discloses a fixture for short-distance chip transfer in chip design. The chip is clamped by the mutual closing of two clamping blocks. However, the chip itself is relatively fragile and can easily be damaged during the clamping process due to uneven clamping surfaces of the fixture.

[0004] For example, the patent with publication number CN220351085U discloses a chip anti-pinch transfer fixture. By setting buffer blocks on two clamping plates, the impact on the chip is reduced, thereby avoiding damage to the chip during clamping. However, this clamping method has a large contact area between the chip and the clamping plates, which is not conducive to subsequent work. Utility Model Content

[0005] To solve or partially solve the problems existing in related technologies, this utility model provides a chip handling fixture, which aims to solve the technical problem that existing fixtures easily damage chips when holding them.

[0006] The aforementioned chip handling fixture includes a fixed plate, a movable plate, a fixed limiting block, a movable limiting block, and a lateral limiting block;

[0007] A movable disc is movably mounted on the fixed disc;

[0008] The fixed plate is provided with two sets of lateral limiting blocks arranged opposite to each other. The upper end of the lateral limiting blocks passes through the moving plate and extends upward. The cavity between the two sets of lateral limiting blocks is a chip clamping station. The lateral limiting blocks are provided with steps for carrying the chip.

[0009] The chip clamping station has a fixed limiting block on the left side that is fixedly connected to the fixed plate, and a movable limiting block on the right side that is fixedly connected to the moving plate. The movable limiting block can move towards or away from the fixed limiting block under the drive of the moving plate.

[0010] The top of the fixed limiting block is provided with a first limiting inclined surface, which makes point contact or line contact with the upper side edge of the chip located in the chip clamping station; or / and the top of the movable limiting block is provided with a second limiting inclined surface, which makes point contact or line contact with the upper side edge of the chip located in the chip clamping station.

[0011] In some solutions, the angle between the projection of the first limiting inclined plane onto the vertical plane and the horizontal plane is 30 to 55 degrees.

[0012] The height of the upper side of the chip is higher than the height of the lowest point of the first limiting slope, but lower than the height of the highest point of the first limiting slope.

[0013] In some designs, the angle between the projection of the second limiting inclined plane onto the vertical plane and the horizontal plane is 30 to 55 degrees.

[0014] The height of the upper side of the chip is higher than the height of the lowest point of the second limiting slope, but lower than the height of the highest point of the second limiting slope.

[0015] In some designs, the locking screw passes through the moving plate and is threaded into the fixed plate.

[0016] In some designs, the moving plate is provided with a limiting guide hole, and the fixed plate is provided with a guide post, the guide post passing through the limiting guide hole;

[0017] When the guide post contacts one end of the limiting guide hole, both sides of the chip abut against the fixed limiting block and the movable limiting block, respectively.

[0018] In some embodiments, each set of the lateral limiting blocks comprises two square lateral limiting blocks, the top of which is provided with a guide ramp.

[0019] In some designs, the fixed limiting block is cylindrical with a conical top.

[0020] In some designs, the movable limiting block is cylindrical with a conical top.

[0021] The technical solution provided by this utility model can include the following beneficial effects:

[0022] This application uses lateral limiting blocks to limit and support the chip on both the front and rear sides; fixed limiting blocks and movable limiting blocks limit the left and right sides of the chip respectively, and make point or line contact with the chip, reducing the contact area with the chip, which facilitates subsequent chip processing. Furthermore, it is less likely to damage the chip, thus improving safety during the chip clamping process.

[0023] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and do not limit the present invention. Attached Figure Description

[0031] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but the scope of protection of the present invention is not limited to the content described.

[0032] Please see Figures 1-4 This application provides a chip handling fixture, including a fixed plate 1, a moving plate 2, a fixed limiting block 3, a movable limiting block 4, and a lateral limiting block 5.

[0033] A movable disk 2 is movably mounted on the fixed disk 1. A pad 8 is provided between the fixed disk 1 and the movable disk 2. The pad 8 supports the movable disk 2, limiting its height and reducing friction, thus making its movement smoother. The pad 8 can be cylindrical, square, or other shapes, and the number of pads 8 can be determined according to the size of the movable disk 2. The movable disk 2 has a limiting guide hole 21, which is an oblong hole. The fixed disk 1 has a guide post 11, the upper end of which passes through the limiting guide hole 21. The diameter of the guide post 11 matches the width of the limiting guide hole 21, thereby limiting the movable direction of the movable disk 2. In some specific embodiments, the positions of the limiting guide holes 21 and the pad 8 are arranged in a one-to-one correspondence.

[0034] The fixed plate 1 is provided with two sets of lateral limiting blocks 5 arranged opposite to each other. Each set of lateral limiting blocks 5 includes two square lateral limiting blocks 5. The upper end of the lateral limiting blocks 5 passes through the moving plate 2 and extends upward. It can be imagined that the moving plate 2 is provided with clearance holes corresponding to the lateral limiting blocks 5 so that the moving plate 2 will not interfere with the lateral limiting blocks 5. The cavity between the two sets of lateral limiting blocks 5 is the chip clamping station 6. The lateral limiting blocks 5 are provided with steps 51 for carrying chips.

[0035] The chip clamping station 6 has a fixed limiting block 3 on its left side, which is fixedly connected to the fixed plate 1. The upper end of the fixed limiting block 3 extends upward through the movable plate 2, and the movable plate 2 also has clearance holes corresponding to the position of the fixed limiting block 3, so that the movable plate 2 will not interfere with the fixed limiting block 3. The chip clamping station 6 has a movable limiting block 4 on its right side, which is fixedly connected to the movable plate 2. The movable limiting block 4 can move towards or away from the fixed limiting block 3 under the influence of the movable plate 2. Thus, when the chip needs to be moved or transferred, the chip is placed in the chip clamping station 6, and its front and rear sides are limited by the lateral limiting blocks 5. Then, the movable limiting block 4 or the movable plate 2 is pushed, causing the movable limiting block 4 to move towards the fixed limiting block 3. This, combined with the fixed limiting block 3 and the movable limiting block 4, limits the left and right sides of the chip, achieving the purpose of firmly clamping the chip in the chip clamping station 6, facilitating chip handling or transfer.

[0036] In this embodiment, when the guide post 11 contacts one end of the limiting guide hole 21, both sides of the chip abut against the fixed limiting block 3 and the movable limiting block 4 respectively. In this way, the distance that the moving disk 2 can move is limited, that is, the distance that the movable limiting block 4 can move to the left is limited, which effectively avoids the problem of the chip being crushed due to the movable limiting block 4 moving too far, and ensures the safety of the chip.

[0037] In this embodiment, the top of the fixed limiting block 3 is provided with a first limiting inclined surface 31. The first limiting inclined surface 31 makes point contact or line contact with the upper side edge of the chip located in the chip clamping station 6. The chip is pressed into the chip clamping station 6 by the first limiting inclined surface 31. At the same time, it avoids the problem of excessive pressure on part of the chip due to insufficient flatness of the chip edge, which would damage the chip. It also avoids the problem of excessive pressure on part of the chip due to insufficient flatness of the fixed limiting block 3 edge, which would damage the chip. This effectively improves the safety of chip clamping.

[0038] Preferably, the angle between the projection of the first limiting inclined surface 31 onto the vertical plane and the horizontal plane is 30 degrees to 55 degrees, such as 30 degrees, 40 degrees, 45 degrees, 50 degrees, 55 degrees and any angle between 30 degrees and 55 degrees; the height of the upper side of the chip is higher than the height of the lowest point of the first limiting inclined surface 31 and lower than the height of the highest point of the first limiting inclined surface 31.

[0039] In this embodiment, the top of the movable limiting block 4 is provided with a second limiting inclined surface 41. The second limiting inclined surface 41 makes point contact or line contact with the upper side edge of the chip located in the chip clamping station 6. The chip is pressed into the chip clamping station 6 by the second limiting inclined surface 41. At the same time, it avoids the problem of excessive pressure on part of the chip due to insufficient flatness of the chip edge, which would damage the chip. It also avoids the problem of excessive pressure on part of the chip due to insufficient flatness of the edge of the movable limiting block 4, which would damage the chip. This effectively improves the safety of chip clamping.

[0040] Preferably, the angle between the projection of the second limiting inclined surface 41 on the vertical plane and the horizontal plane is 30 degrees to 55 degrees, such as 30 degrees, 40 degrees, 45 degrees, 50 degrees, 55 degrees and any angle between 30 degrees and 55 degrees; the height of the upper side of the chip is higher than the height of the lowest point of the second limiting inclined surface 41 and lower than the height of the highest point of the second limiting inclined surface 41.

[0041] In this embodiment, the top of the side limiting block 5 is provided with a guide slope 52, which guides the chip placement process in the chip clamping station 6 to ensure that the chip can be placed smoothly and correctly in the chip clamping station 6.

[0042] In this embodiment, the fixed limiting block 3 is cylindrical, square or other shapes, and the top of the fixed limiting block 3 is conical to guide the process of placing the chip into the chip clamping station 6.

[0043] In this embodiment, the movable limiting block 4 is cylindrical, square or other shapes, and the top of the movable limiting block 4 is conical, so as to guide the process of placing the chip into the chip clamping station 6.

[0044] In this embodiment, the locking screw 7 passes through the movable disk 2 and is threadedly connected to the fixed disk 1. Thus, after the movable disk 2 is pushed to the designated position, the position of the movable disk 2 can be fixed simply by tightening the locking screw 7, which is convenient to use. Preferably, the end of the locking screw 7 is butterfly-shaped, which improves the ease of rotating the locking screw 7.

[0045] The various embodiments of the present invention have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or improvement of the technology in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
