Description

Technical Field

[0001] The utility model belongs to the technical field of clamping devices, in particular to a eutectic chip clamping device. Background Art

[0002] Eutectic chips are chips formed by mixing two or more materials in a eutectic manner and cooling and solidifying. In the manufacturing process of eutectic chips, fixtures are essential tools used to fix and clamp the chips to ensure the stability and accuracy of the chips during processing. Eutectic chips require various operations during processing, such as cutting, grinding, and etching. The fixture can provide stable support and fixation to prevent the chip from moving or deforming during processing, thereby ensuring the accuracy and consistency of processing.

[0003] Due to the characteristics of the fixture itself, it is not possible to use soft materials. Therefore, the existing fixture cannot fully adapt to the shape and size differences of the chip when clamping the fragile chip, which causes the fixture to exert excessive pressure on the chip or insufficient clamping force, thereby causing damage to the chip.

[0004] The patent with publication number CN116423007A discloses a two-degree-of-freedom tin-plated chip clamping device. By adjusting the screws and the movement of the clamping rod in the slide beam, the chip can be freely moved in two directions, and the clamping space can be adjusted in time according to the size of the chip to ensure the stability of the chip clamping. When clamping the chip, the driving part of this clamp adopts a screw mechanism, which is a labor-saving mechanism. Therefore, the chip can be easily damaged in the process of clamping the chip.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example

[0026] A eutectic chip clamping device, such as Figure 1 As shown, it includes a mounting body 1, a movable clamping plate 2, a fixed clamping plate 5, a screw rod 13 and an auxiliary device for positioning;

[0027] The fixed clamping plate 5 is fixedly connected to one side of the top of the installation body 1, the movable clamping plate 2 is movably connected to the other side, the screw rod 13 is rotatably connected to the installation body 1, and the movable clamping plate 2 is threadedly connected to the screw rod 13; the in-position auxiliary device includes an in-position contact piece 4, a limit clamping rod 16 and a mating head 11;

[0028] like Figures 1 to 3 As shown, the in-place contact piece 4 is movably connected to the bottom of the fixed splint 5, and one side of the in-place contact piece 4 extends out and faces the movable splint 2; the mating head 11 is fixedly connected to the outside of the screw rod 13; the middle part of the limit clamp rod 16 is rotatably connected to the mounting body 1, and one side of the limit clamp rod 16 faces the in-place contact piece 4, and the other side faces the mating head 11.

[0029] Specifically, when in use, the chip 3 is placed between the fixed clamping plate 5 and the movable clamping plate 2, and the screw rod 13 is rotated. After the screw rod 13 rotates, it drives the movable clamping plate 2 to move. The movable clamping plate 2 first contacts the chip 3 and pushes the chip 3 toward the fixed clamping plate 5. In the process of approaching the fixed clamping plate 5, the chip 3 will first contact the in-place contact member 4, and then the in-place contact member 4 will move into the fixed clamping plate 5. The in-place contact member 4 contacts the limit clamping rod 16 and pushes the limit clamping rod 16 to rotate. The other side of the limit clamping rod 16 supports the mating head 11, making it difficult to continue to rotate the screw rod 13. Because of the restriction, the screw rod 13 cannot drive the movable clamping plate 2 to continue to increase the clamping force, thereby ensuring the safety of the chip 3 and effectively preventing the chip 3 from being damaged by clamping. This structure can stably clamp the chip 3 and prevent the chip 3 from being damaged due to excessive force applied to the chip 3.

[0030] In a preferred embodiment, if Figure 1 to Figure 2 As shown, a slot 9 is provided on one side of the top of the mounting body 1, and one side of the bottom of the fixing clamp 5 is clamped in the slot 9. This design realizes a detachable connection between the fixing clamp 5 and the mounting body 1, and is convenient for disassembling or replacing the fixing clamp 5.

[0031] In a preferred embodiment, if Figure 1 to Figure 2 As shown, the mounting body 1 is a hollow structure, and connecting grooves 8 are provided on both sides of the mounting body 1; the screw rod 13 is rotatably connected in the mounting body 1 and one side of the screw rod 13 extends out of the mounting body 1;

[0032] A bottom slider 7 is movably connected in the mounting body 1 and is threadedly connected to a screw rod 13 . Connecting rods 6 are fixedly connected to both sides of the movable clamping plate 2 , and the connecting rods 6 are also fixedly connected to the bottom slider 7 .

[0033] Specifically, the movable clamping plate 2 is threadedly connected to the screw rod 13 through the connecting rod 6 and the bottom slider 7. This design is to ensure that the bottom of the installation body 1 can be set as a complete plane, and there is no need to use a groove to match the movable clamping plate 2 with the screw rod 13. Setting the top of the installation body 1 as a complete plane can facilitate the placement and clamping of the chip 3.

[0034] In a preferred embodiment, if Figure 1 to Figure 2 As shown, a rotating head 10 is fixedly connected to one side of the screw rod 13. The rotating head 10 is used to facilitate the rotation of the screw rod 13.

[0035] In a preferred embodiment, if Figure 1 to Figure 2As shown, a mounting cavity 14 is provided at the bottom of the fixed clamping plate 5, and a slide groove 15 is provided on the side wall of the mounting cavity 14; one side of the in-position contact member 4 is movably connected in the mounting cavity 14; a slider is also fixedly connected to the in-position contact member 4, and the slider is slidably connected in the slide groove 15. The mounting cavity 14 can facilitate the in-position contact member 4, and the design of the slide groove 15 and the slide groove 15 is to ensure the stability of the in-position contact member 4 when it moves, and to prevent the in-position contact member 4 from falling off from the fixed clamping plate 5 on the one hand.

[0036] In a preferred embodiment, if Figure 1 to Figure 2 As shown, a tension spring 17 is provided at the bottom of the limit card rod 16; one end of the tension spring 17 is connected to the limit card rod 16, and the other end is connected to the mounting body 1. The tension spring 17 is used to make the top of the limit card rod 16 always contact with the in-position contact piece 4. When the chip 3 is clamped, the limit card rod 16 rotates and pulls the tension spring 17 to lengthen. When the chip 3 is released, the tension spring 17 resets and pulls the limit card rod 16 to reset. During the reset process, the limit card rod 16 pushes the in-position contact piece 4 to extend to complete the reset.

[0037] In a preferred embodiment, if Figure 1 to Figure 2 As shown, a plurality of positioning protrusions are fixedly connected to the end surface of the mating head 11 facing the limiting clamping rod 16, and the positioning protrusions are evenly spaced along the circumferential direction of the mating head 11. The positioning protrusions are used to ensure that the limiting clamping rod 16 can stably clamp the mating head 11 after contacting the mating head 11. The uniform arrangement of multiple positioning protrusions is to further ensure that the limiting clamping rod 16 can stably clamp the mating head 11.
