Description

Technical Field

[0001] The present application relates to the field of chip clamping technology, and in particular to a micro chip clamp. Background Art

[0002] In the field of chip manufacturing and processing, with the continuous advancement of technology, chips are increasingly used in various fields, from electronic devices to industrial automation. Chips are indispensable in all aspects of chip manufacturing and testing. Fixing and clamping the chip is a crucial step in the chip manufacturing and testing process, which is directly related to the chip processing accuracy and quality. A good chip fixing method can ensure that the chip remains stable during processing and testing, avoiding processing errors or testing inaccuracies caused by shaking or displacement, which is of great significance for improving chip production efficiency and performance.

[0003] In the past, two conventional methods were used to secure chips larger than 1mm in both length and width. One method was vacuum suction, which created a vacuum force to hold the chip in place. The other was a sliding clamp, which used sliding clamps to hold the chip. Both methods met basic securing requirements for larger chips and provided a certain degree of stability during chip processing and testing.

[0004] Regarding the aforementioned related technologies, existing fixing methods exhibit significant drawbacks when the chip's length or width is less than 1mm. Vacuum suction methods lack sufficient holding force, making it difficult to stably secure small chips. Furthermore, sliding clamps can easily cause the chip to fly off, resulting in damage or loss. Therefore, a structure that improves the stability of microchip clamping is urgently needed. Summary of the Invention

[0005] In order to improve the stability of microchip clamping, the present application provides a microchip clamp.

[0006] This application provides a microchip fixture that adopts the following technical solution: A microchip fixture comprises a fixture base, a guide rod, a clamping block and a tightening bolt; The clamp seat is provided with two guide rods arranged side by side, the guide rods are parallel to the first direction, the clamping block is provided between the two guide rods, and a slider is fixedly connected to each end of the clamping block. The slider is sleeved on the guide rods and slides along the first direction, and a clamping area is formed between two adjacent clamping blocks; The clamping block is fixedly connected to an elastic clamping tooth on one side close to the clamping area, the clamping block is provided with a first abutting surface on one side close to the elastic clamping tooth, and a second abutting surface on the other side, a clamping gap is formed between the elastic clamping tooth of one clamping block and the second abutting surface of the other clamping block, an elastic gap is provided between one side of the elastic clamping tooth and the first abutting surface, and the elastic clamping tooth has a force to move toward a side away from the first abutting surface when it is deformed in a restorable manner; The tightening bolt is parallel to the first direction, is threadedly connected to the clamp seat, and has an end portion pressed against the side wall of the clamping block.

[0007] By adopting the above technical solution, the chip is placed in the clamping gap by setting a clamping block and elastic clamping teeth, and the chip is clamped by the elastic clamping teeth and the clamping block. When the chip needs to be fixed, the tightening bolt is rotated, and the tightening bolt pushes the clamping block, driving the clamping block to slide along the first direction until the elastic clamping teeth and the clamping block clamp and fix the chip. When the elastic clamping teeth are subjected to external force, the elastic clamping teeth are deformed and move toward the side close to the first abutting surface, further clamping the chip more firmly, and setting multiple clamping blocks can achieve clamping and fixation of multiple chips.

[0008] Optionally, a plurality of the elastic clamping teeth are arranged at intervals along the second direction, and a tooth groove is formed between two adjacent elastic clamping teeth.

[0009] By adopting the above technical solution, multiple chips can be clamped by setting up multiple elastic clamping teeth. At the same time, tooth grooves are provided between two adjacent elastic clamping teeth to ensure uniform deformation of the elastic clamping teeth, thereby improving the uniformity of the clamping force.

[0010] Optionally, the clamp seat is provided with a first accommodating groove along the first direction for accommodating the guide rod, and the clamp seat is provided with a second accommodating groove along the third direction for accommodating the clamping block, the second accommodating groove and the first accommodating groove are connected in the second direction, the side wall of the slider is in contact with the side wall of the first accommodating groove, and the top wall of the slider block is in contact with the top wall of the first accommodating groove.

[0011] By adopting the above technical solution, by providing the first accommodating groove and the second accommodating groove, the first accommodating groove accommodates the guide rod, and the second accommodating groove accommodates the fixture seat, and it is convenient for personnel to place the chip.

[0012] Optionally, the elastic clamping teeth are provided with a special-shaped groove along the second direction, and the special-shaped groove is communicated with the elastic gap.

[0013] By adopting the above technical solution and setting special-shaped grooves, the elastic deformation range of the elastic clamping teeth can be increased. When the clamping block is pushed by the tightening bolt, the elastic clamping teeth are more likely to deform, thereby adapting to chips of different thicknesses and ensuring uniform distribution of the clamping force.

[0014] Optionally, the clamping block is provided with an abutment groove along the second direction on one side of the second abutment surface, the abutment groove passes through the top wall of the clamping block along the first direction, the side wall of the abutment groove is a contact surface, the chip is clamped between the elastic clamping teeth and the bottom wall of the abutment groove, and the side wall of the chip is in contact with the contact surface.

[0015] By adopting the above technical solution, by opening an abutment groove on the clamping block, the chip is clamped in the clamping gap formed by the abutment groove and the elastic clamping teeth, so that the side wall of the chip fits with the contact surface. When the tightening bolt rotates and drives multiple clamping blocks to abut each other, the contact surface of the abutment groove provides support force for the chip, thereby reducing the occurrence of the chip being clamped and flying.

[0016] Optionally, a wedge-shaped groove is provided on one side of the elastic clamping tooth close to the abutting groove, and the chip is clamped between the wall of the wedge-shaped groove and the wall of the abutting groove of the clamping block.

[0017] By adopting the above technical solution, a wedge-shaped groove is opened on one side of the elastic clamping tooth. When the clamping block is pushed by the tightening bolt, the deformation of the elastic clamping tooth will exert concentrated pressure along the inclined direction of the wedge-shaped groove, thereby pressing the chip more tightly against the abutting groove wall of the clamping block, thereby improving the clamping stability. In addition, the wedge-shaped groove expands the contact area between the elastic clamping tooth and the chip, so that the clamping force is evenly distributed on the side wall of the chip.

[0018] Optionally, a plurality of shifting holes are formed through the top wall of the clamping block along the third direction, and each of the shifting holes is communicated with one of the clamping gaps.

[0019] By adopting the above technical solution and providing the shifting hole, it is convenient for a person to insert tweezers into the shifting hole and shift the chip to adjust the position of the chip.

[0020] Optionally, a support protrusion is fixedly connected to a side of each clamping block away from the elastic clamping teeth, the support protrusion is located at an end of the clamping block away from the dial hole, and the top wall of the support protrusion is arranged flush with the contact surface.

[0021] By adopting the above technical solution, a support bump is set to fill the gap on one side of the elastic clamping tooth, and the chip is placed in the clamping gap from the side close to the support bump. During the placement process, the support bump provides auxiliary support for the chip to prevent it from falling when placed.

[0022] Optionally, one side of the clamping block is in contact with a side wall of the first accommodating groove close to the shifting hole, and a placement space is provided between the other side of the clamping block and another side wall of the first accommodating groove.

[0023] By adopting the above technical solution, one side of the clamping block is fitted with one side of the first receiving groove, and multiple chips are placed in the clamping gap. The chip at the outermost side is in contact with the wall of the first receiving groove to limit the chip and prevent it from falling.

[0024] Optionally, the fixture seat is made of copper.

[0025] By adopting the above technical solution, the clamp seat is made of copper, which has good thermal conductivity and is conducive to dissipating heat for the chip during the clamping process.

[0026] In summary, this application includes at least one of the following beneficial technical effects: The present application places the chip in the clamping gap by providing a clamping block and elastic clamping teeth, and the chip is clamped by the elastic clamping teeth and the clamping block. When the chip needs to be fixed, the tightening bolt is rotated, and the tightening bolt pushes the clamping block, driving the clamping block to slide along the first direction until the elastic clamping teeth and the clamping block clamp and fix the chip. When the elastic clamping teeth are subjected to external force, the elastic clamping teeth are deformed and move toward the side close to the first abutting surface, further clamping the chip more firmly. In addition, providing multiple clamping blocks can achieve clamping and fixing of multiple chips. The present application provides an abutment groove on the clamping block, and the chip is clamped in the clamping gap formed by the abutment groove and the elastic clamping teeth, so that the side wall of the chip fits in contact with the contact surface. When the tightening bolt rotates and drives the multiple clamping blocks to abut each other, the contact surface of the abutment groove provides support for the chip, thereby reducing the possibility of the chip being clamped and flying away. This application sets a support bump to fill the gap on one side of the elastic clamping teeth. The chip is placed in the clamping gap from the side close to the support bump. During the placement process, the support bump provides auxiliary support for the chip to prevent it from falling when placed. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] The following is combined with Figure 1-7 This application is described in further detail.

[0030] The present application discloses a microchip fixture. For ease of description, this application introduces directional terms such as a first direction, a second direction, and a third direction to form a three-dimensional reference direction. The directional terms used, such as "first direction, second direction, and third direction," can be specifically described with reference to the figure, where the first direction is represented by X, the second direction by Y, and the third direction by Z, and the first, second, and third directions are perpendicular to each other.

[0031] Reference Figure 1 and Figure 2 The microchip fixture includes a fixture base 1, a guide rod 2 and a clamping block 3. The fixture base 1 is provided with two guide rods 2 arranged side by side, and the guide rods 2 are parallel to the first direction. The clamping block 3 is arranged between the two guide rods 2. Both ends of the clamping block 3 are fixedly connected with a slider 31. Each slider 31 is sleeved on a guide rod 2 and slides along the first direction. A clamping area 32 is provided between two adjacent clamping blocks 3. An elastic clamping tooth 33 is fixedly connected to one side of the clamping block 3, and the elastic clamping tooth 33 is located on the side close to the clamping area 32. The clamping block 3 is provided with a first abutting surface 34 on one side of the elastic clamping tooth 33, and a second abutting surface 35 on the other side. A clamping gap 36 is formed between the elastic clamping tooth 33 of one clamping block 3 and the second abutting surface 35 of the other clamping block 3, and the chip 01 is clamped in the clamping gap 36; Reference Figure 3 and Figure 4There is an elastic gap 331 between one side of the elastic clamping tooth 33 and the first abutting surface 34, and the elastic clamping tooth 33 has the force to move toward the side away from the first abutting surface 34 under recoverable deformation; each chip 01 is clamped between the elastic clamping tooth 33 and the second abutting surface 35 of the other clamping block 3. When the elastic clamping tooth 33 is in normal state, there is an elastic gap 331 between the elastic clamping tooth 33 and the first abutting surface 34 of the clamping block 3. When the clamping block 3 is pressed tightly along the first direction, each clamping block 3 slides along the first direction, and one side of the elastic clamping tooth 33 is squeezed and compressed to produce deformation, and the width of the elastic gap 331 is reduced, and one side of the elastic clamping tooth 33 approaches the first abutting surface 34, further clamping the chip 01 more firmly.

[0032] Reference Figure 2 In this embodiment, the cross-section of the clamp seat 1 is rectangular, and the material of the clamp seat 1 is copper. Copper has good thermal conductivity and wear resistance. The copper clamp seat 1 can quickly conduct the heat generated when the chip 01 is clamped, preventing local overheating from affecting the performance of the chip 01, and can reduce deformation or wear caused by long-term use.

[0033] Reference Figure 3 In order to improve the clamping effect, multiple elastic clamping teeth 33 are arranged at intervals along the second direction, and tooth grooves 332 are formed between two adjacent elastic clamping teeth 33. Multiple elastic clamping teeth 33 are fixedly connected to one side close to the first abutting surface 34. Multiple elastic clamping teeth 33 can clamp and fix multiple chips 01.

[0034] Reference Figure 5 In order to apply external force to the clamping block 3, the microchip clamp also includes a tightening bolt 4, which is threadedly connected to the clamp seat 1. A threaded hole 11 is opened on one side of the clamp seat 1 along the first direction. One end of the tightening bolt 4 passes through the threaded hole 11 of the clamp seat 1 and is tightened against the second abutting surface 35 of a clamp seat 1, and the other end is located on the outside of the clamp seat 1. Rotating the tightening bolt 4 further drives multiple clamping blocks 3 to slide along the first direction, and the elastic clamping block 3 further deforms to clamp and fix the chip 01. In this embodiment, there are 6 clamping blocks 3 along the first direction, and each clamping block 3 is connected to 10 elastic clamping teeth 33.

[0035] Reference Figure 5In order to install the guide rod 2, a first accommodating groove 12 for accommodating the guide rod 2 is opened on the bottom wall of the clamp seat 1 along the first direction, and a second accommodating groove 13 for accommodating the clamping block 3 is opened through the clamp seat 1 along the third direction. The second accommodating groove 13 and the first accommodating groove 12 are connected in the second direction, and the side wall of the slider 31 is in contact with the side wall of the first accommodating groove 12, and the top wall of the slider 31 is in contact with the top wall of the first accommodating groove 12. The guide rod 2 is clamped in the first accommodating groove 12, and the clamping block 3 is located in the second accommodating groove 13. By setting the first accommodating groove 12 and the second accommodating groove 13, it is convenient for people to put in and take out the chip 01.

[0036] Reference Figure 4 In order to make it easier for the elastic clamping teeth 33 to deform, the elastic clamping teeth 33 are provided with special-shaped grooves 333 along the second direction. The special-shaped grooves 333 are connected to the elastic gap 331. By providing the special-shaped grooves 333, when the elastic clamping block 3 is subjected to external force, the deformation space on one side of the elastic clamping block 3 is larger and easier to deform, thereby improving the clamping and fixing effect of the chip 01.

[0037] Reference Figure 4 and Figure 6 In order to reduce the possibility of chip 01 being pinched and flying away, the clamping block 3 is provided with an abutment groove 351 along the second direction on one side of the second abutment surface 35. The abutment groove 351 penetrates the top wall of the clamping block 3 along the first direction. The side wall of the abutment groove 351 is a contact surface 3511. The chip 01 is clamped between the elastic clamping teeth 33 and the first abutment surface 34 of the clamping block 3. The side wall of the chip 01 is in contact with the contact surface 3511. The contact surface 3511 provides support for the chip 01, thereby reducing the possibility of chip 01 being pinched and flying away.

[0038] Reference Figure 4 and Figure 6 In order to further improve the clamping effect of the elastic clamping teeth 33 on the chip 01, a wedge-shaped groove 334 is provided on the side of the elastic clamping teeth 33 close to the abutment groove 351. The chip 01 is clamped between the groove wall of the wedge-shaped groove 334 and the groove wall of the abutment groove 351 of the clamping block 3. By providing the wedge-shaped groove 334 on the elastic clamping teeth 33, when the clamping block 3 is pushed by the tightening bolt 4, the deformation of the elastic clamping teeth 33 will apply concentrated pressure along the inclined direction of the wedge-shaped groove 334, thereby pressing the chip 01 more tightly against the abutment groove 351 of the clamping block 3 wall, improving the stability of clamping; in addition, the wedge-shaped groove 334 expands the contact area between the elastic clamping teeth 33 and the chip 01, so that the clamping force is evenly distributed on the side wall of the chip 01, rather than concentrated on a single corner or edge, which can not only reduce the risk of damage to the chip 01 due to excessive local stress, but also prevent the chip 01 from sliding or offsetting during the clamping process; in addition, the chip 01 is confined in the clamping area 32 of the wedge-shaped groove 334 and the abutment groove 351, and the lateral movement is constrained, further reducing the possibility of the chip 01 popping out during the tightening process.

[0039] Reference Figure 7 In order to facilitate personnel to move the chip 01 in the clamping gap 36, a plurality of shifting holes 14 are opened along the third direction on the top wall of the clamp seat 1. Each shifting hole 14 is connected to a clamping gap 36. By setting the shifting holes 14, personnel can use tweezers to shift the chip 01 in the shifting hole 14, thereby adjusting the position of the chip 01.

[0040] Reference Figure 6 and Figure 7 , the personnel slides the chip 01 into the clamping gap 36 from the side away from the toggle hole 14. During the placement process, the chip 01 located on the side may fall without support. For this reason, each clamping block 3 is fixedly connected to the side away from the elastic clamping block 3 with a supporting protrusion 37. The supporting protrusion 37 is located at the end of the clamping block 3 away from the toggle hole 14, and the top wall of the supporting protrusion 37 is flush with the contact surface 3511. During the placement process, the chip 01 is supported by the supporting protrusion 37 to reduce the possibility of the chip 01 falling.

[0041] Reference Figure 7 In order to further limit the chip 01, one side wall of the first accommodating groove 12 is the limiting side 121, and the other side wall of the first accommodating groove is the placing side 122. The limiting side 121 and the dial hole 14 are located on the same side of the clamp seat 1. One side of the clamping block 3 is in contact with the limiting side 121, and there is a placing space 38 between the other side and the placing side 122. Multiple chips 01 are placed in the clamping gap 36, and the chip 01 located on the side is in contact with the limiting side 121. The limiting side 121 limits the chip 01 to prevent the chip 01 from falling.

[0042] Reference Figure 7 In order to facilitate the installation of the clamp base 1 on other structures, the clamp base 1 is provided with a plurality of positioning holes 15 along the first direction for easy installation.

[0043] The implementation principle of a microchip clamp in an embodiment of the present application is: multiple chips 01 are slid into the clamping gap 36 from the placement side 122 in sequence. After the placement is completed, the personnel can use tweezers to reach into the dial hole 14 to dial the position of the chip 01 to ensure that the chip 01 is clamped and fixed by the elastic clamping teeth 33, and the tightening bolt 4 is rotated. The elastic clamping teeth 33 of the clamping block 3 on the outermost side are pressed against the wall of the second accommodating groove 13. According to the different widths of the chip 01, the elastic clamping teeth 33 of each clamping block 3 are deformed under the action of external force, so that the chip 01 is clamped more firmly. When the chip 01 needs to be picked up or placed, the tightening bolt 4 can be rotated in the opposite direction.

[0044] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
