Description

Technical Field

[0001] The invention relates to the technical field of chip processing, and in particular to a pair of chip tweezers. Background Art

[0002] The infrared focal plane detector is a device used to detect infrared radiation. The chip inside is usually small. The flip-chip process plays an important role in connecting the upper and lower parts of the production process. The process requires manual cleaning and flipping before flip-chip welding. After the operation, the chip needs to be removed and transferred. Manual operation usually uses tweezers for clamping, and in order to avoid damaging the indium column on the front of the chip, it is necessary to clamp the chip by the edge.

[0003] CN220762300U discloses a pair of tweezers for wafer transfer, comprising a tweezer body; two clamping ends of the tweezer body are respectively provided with clamping limit grooves for the side edges of the wafer to extend into; the clamping limit grooves are provided with at least a lower limit surface and a side limit surface that can contact the side edges of the wafer.

[0004] The above technical solution uses the lower limit surface and the side limit surface in the clamping limit groove to limit the side edges of the chip, so that the side edges of the chip are subjected to force on both the side and bottom surfaces, thereby improving the stability of the clamped chip and avoiding the risk of the chip falling and breaking due to unstable clamping. Furthermore, the side limit clamping design of the clamping limit groove can also avoid the tweezers body from contacting the surface of the chip during clamping as much as possible, so as to avoid damaging the chip surface.

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0036] Example 1

[0037] refer to Figures 1 to 6A chip tweezers, comprising a tweezers body 1, a connecting member 2, two clamping ends of the tweezers body 1 are respectively provided with clamping components 11 for clamping the chip; the clamping components 11 are rotatably connected to the corresponding clamping ends;

[0038] Both ends of the connecting member 2 are connected to two clamping assemblies 11 respectively;

[0039] The connecting member 2 is used to keep the two clamping assemblies 11 in a synchronously rotatable state at any clamping distance.

[0040] In this design, the operator pinches the tweezers body 1 to make the two clamping ends move toward each other, and clamps the chip through the clamping components 11 on the two clamping ends. If the clamped chip is facing up, after clamping, while the tweezers are pinched, the operator can drive the two clamping components 11 to rotate synchronously through the connecting piece 2 to turn over the chip between the two clamping components 11. After turning over, the operator releases the tweezers body 1 and puts down the chip, and the back of the chip faces up. In this way, the need for manual loosening and flipping before clamping is avoided, thereby improving the safety of chip transfer.

[0041] In a preferred embodiment, a movable portion is provided on the connecting member 2, at least one clamping assembly 11 is provided with a connecting rod 12 of a prismatic structure, and movable grooves 21 matching the number of the connecting rods 12 are provided on the connecting member 2, and the connecting member 2 is movably connected to the connecting rod 12 through the movable grooves 21 to form a movable portion;

[0042] Specifically, in this embodiment, there is one connecting rod 12, one end of the connecting member 2 is fixedly connected to the clamping assembly 11, and the other end is movably connected to the connecting rod 12 through the movable groove 21. In actual use, when the tweezers body 1 is clamped and deformed, the clamping assembly 11 provided with the connecting rod 12 can drive the connecting rod 12 to move, and the movable groove 21 can provide a movable space for the movement of the connecting rod 12, thereby realizing the function of ensuring rotation in the clamped state.

[0043] Of course, the operator can also set two connecting rods 12 according to actual conditions, that is, both ends of the connecting member 2 are movably connected to the connecting rod 12, and the same function can be achieved. It should be noted here that the structure of the connecting rod 12 must be a prismatic structure, so as to ensure that one end of the movably connected end can drive the clamping assembly 11 to rotate.

[0044] In other embodiments, the connecting member 2 is at least partially flexible, and the connecting member 2 is a connecting member 2 made of a flexible material, or the connecting member 2 has a flexible portion;

[0045] The flexible material can be silicone, plastic, rubber, connecting rope, flexible metal, etc. In the flexible part, there can be two connectors 2, and one end of the two connectors 2 is connected to the two clamping components 11 respectively, and the other ends of the two connectors 2 are connected by a flexible material, and of course, they can also be integrally formed.

[0046] Preferably, the clamping assembly 11 includes a clamping block 111 and a rotating seat 112, the rotating seat 112 is rotatably connected to the clamping end, the clamping block 111 and the rotating seat 112 are connected, the two clamping blocks 111 are arranged opposite to each other, and the two ends of the connecting member 2 are respectively connected to the two rotating seats 112, or respectively connected to the two clamping blocks 111.

[0047] Specifically, the rotating seat 112 mainly provides support and rotation for the clamping block 111; in a preferred embodiment, the two ends of the connecting member 2 are respectively connected to the two rotating seats 112; in other embodiments, the two ends of the connecting member 2 are respectively connected to the two clamping blocks 111. Both methods can drive the two clamping blocks 111 to rotate synchronously through the connecting member 2, and the first method is adopted in this embodiment.

[0048] A gasket 1121 may be provided between the rotating seat 112 and the clamping end to prevent the rotating seat 112 and the clamping end from being worn.

[0049] Preferably, the clamping block 111 is hinged on the rotating seat 112 , and the swing axis of the clamping block 111 is parallel to the swing axis of the tweezers body 1 .

[0050] In actual use, the clamping block 111 is hinged on the rotating seat 112, so that when clamping the edge of the chip, the clamping block 111 can automatically stick to the edge of the chip to achieve parallel clamping, so as to ensure the stability of clamping and reduce the force on the right-angle edge of the chip, thereby avoiding falling due to unstable clamping and edge collapse due to uneven clamping force. At the same time, with the function of the rotating seat 112 and the connecting piece 2, the chip can be flipped under stable clamping.

[0051] Preferably, an elastic telescopic member 22 is provided on the connecting member 2, and a limiting groove 13 matching the elastic telescopic portion of the elastic telescopic member 22 is provided on the clamping end corresponding to the position of the elastic telescopic member 22, and the limiting grooves 13 are symmetrically arranged.

[0052] It should be noted here that, in the present embodiment, the elastic telescopic member 22 adopts a spring plunger. In the initial state, the power output end of the spring plunger is located in the limit groove 13. When there is no external force, the bracket is in a fixed state. When the external force drives the bracket to rotate, the spring of the spring plunger is compressed, so that the power output end is separated from the limit groove 13. After the bracket rotates 180°, the spring plunger is embedded in another limit groove 13 and fixed. At this time, the chip has just been turned over, which is convenient for the operator to operate.

[0053] Preferably, an antistatic silicone pad 1111 is provided on the clamping surface of the clamping block 111. The antistatic silicone pad 1111 can effectively suppress the generation of static electricity, thereby preventing the accumulation of static charges. At the same time, the antistatic silicone pad 1111 can increase the friction during clamping, ensuring that the chip does not slide or fall during the clamping process, thereby ensuring the accuracy and safety of the operation.

[0054] Preferably, the tweezers body 1 comprises a tweezers tail 101, a first tweezers handle 102, a second tweezers handle 103, a first tweezers head 104 and a second tweezers head 105;

[0055] The first tweezer handle 102 and the second tweezer handle 103 are arranged in a V shape, and one end of each of them is connected to the tweezer tail 101; the first tweezer head 104 is connected to the other end of the first tweezer handle 102;

[0056] The second tweezer head 105 is connected to the other end of the second tweezer handle 103 and is arranged parallel to the first tweezer head 104;

[0057] The two clamping ends are respectively located on the first tweezer head 104 and the second tweezer head 105 .

[0058] For details, reference may be made to the existing tweezers design, and the structure of the tweezers body 1 will not be described in detail in this embodiment.

[0059] Preferably, the first tweezers handle 102 and the second tweezers handle 103 are both provided with an anti-skid structure 106. When in use, the anti-skid structure 106 can increase the contact friction between the fingers and the first tweezers handle 102 and the second tweezers handle 103 to prevent the fingers from slipping out during use.

[0060] In this embodiment, a limiting ring 3 is further included, and the limiting ring 3 is used to enable the two clamping assemblies 11 to maintain a required clamping distance.

[0061] When in use, the operator can adjust the position of the limit ring 3 to lock the first tweezers handle 102 and the second tweezers handle 103 at a preset clamping angle, thereby avoiding the need for the operator to pinch the first tweezers handle 102 and the second tweezers handle 103 for a long time. Specifically, after completing the chip clamping, the operator adjusts the limit ring 3 to keep the first tweezers handle 102 and the second tweezers handle 103 in a clamping state, and then swings the connecting piece 2 to rotate the two clamping blocks 111 to turn the chip over.

[0062] Furthermore, the limiting ring 3 is a limiting ring 3 made of elastic material, and the inner side of the limiting ring 3 is provided with an anti-skid layer 31. The elastic material can adapt to the change in the spacing between the first forceps handle 102 and the second forceps handle 103, and the anti-skid layer 31 can ensure the stability of the limiting ring 3.

[0063] Although the embodiments of the present application have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present application, and that the scope of the present application is defined by the claims and their equivalents.
