Description

Technical Field

[0001] This utility model relates to a clamping device for chip melting and welding, belonging to the field of chip melting and welding technology. Background Technology

[0002] Chip fusion soldering, simply put, is the process of bonding a chip and a circuit board together using solder, similar to soldering but more precise. The principle is as follows: first, the solder (usually a tin-silver alloy or a gold-tin alloy) is heated to a molten state (around 200-450°C), then the molten solder flows between the chip and the substrate, and after cooling, a strong connection is formed.

[0003] Currently, some mechanized chip clamping devices cannot adjust the chip after positioning and clamping it. If fine-tuning of the chip is required, personnel need to operate the clamping mechanism to cancel the clamping of the chip and then clamp it again. Repeating this process will lead to a decrease in soldering efficiency.

[0004] Therefore, there is an urgent need to improve the clamping equipment used for chip melting and soldering in order to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this invention is to provide a clamping device for chip melting and welding. The operator can make small adjustments to the pressed chip through a fine-tuning mechanism, so that the position of the chip can be adjusted by the operator so that the operator can process it.

[0006] To achieve the above objectives, the main technical solution adopted by this utility model includes: a clamping machine and a pressing base fixedly installed at the pressing end of the clamping machine, wherein a fine adjustment mechanism is provided at the bottom of the pressing base;

[0007] The fine-tuning mechanism includes a fine-tuning base that is slidably connected to the inner wall of the lower base, two limiting screws for limiting the position of the fine-tuning base, and two adjusting teeth that are threadedly connected to the two limiting screws.

[0008] The adjusting tooth extends to the outside of the pressing base on one side.

[0009] Preferably, the pressing base has through slots on both sides to allow the adjusting teeth to extend outward.

[0010] Preferably, four movable blocks are fixedly arranged on the outer side of the fine-tuning base, and a guide groove is provided on the lower half of the inner side of the pressing base to slide and connect with the movable blocks.

[0011] Preferably, a placement base is provided directly below the fine-tuning base and is fixedly connected to the bottom surface of the clamping machine. The placement base is used for placing the chip.

[0012] Preferably, a fixed platform is fixedly provided on one side of the placement base, and the fixed platform is rotatably connected to the magnifying glass via a folding rod and a rotating ball.

[0013] Preferably, there are two rotating balls, one of which is disposed on the upper end of the fixed platform, and an extension rod is connected between the two rotating balls. The other rotating ball is connected to the folding rod on one side, and the magnifying glass is fixedly disposed on the end of the folding rod away from the rotating ball.

[0014] Preferably, each of the two rotating spheres is fixedly provided with a connecting rod that is rotatably connected to the folding rod, the extension rod, and the fixed platform.

[0015] This utility model has at least the following beneficial effects:

[0016] The fine-tuning base is slidably connected to the pressing base via a moving block, allowing the operator to adjust the position of the chip pressed by the fine-tuning base by pushing it. At the same time, the guide groove not only guides the movement of the fine-tuning base, but also presses the fine-tuning base, making it less prone to shaking when clamping and positioning the chip.

[0017] When further positioning of the chip is required, the adjusting gear is rotated so that it can drive the limit screw that is threadedly connected to it to move up and down. This helps to limit the movement of the lower base to the fine-tuning base, thereby further positioning the chip. Attached Figure Description

[0024] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0025] Examples, such as Figures 1-4 As shown, a chip melting and welding clamping device includes a clamping machine 1 and a pressing base 7 fixedly installed at the pressing end of the clamping machine 1. The bottom of the pressing base 7 is provided with a fine adjustment mechanism, which allows the operator to make small adjustments to the pressed chip so that the position of the chip can be adjusted by the operator so that the operator can process it.

[0026] The fine-tuning mechanism includes a fine-tuning base 8 that is slidably connected to the inner wall of the lower base 7, two limiting screws 14 for limiting the position of the fine-tuning base 8, and two adjusting teeth 11 that are threadedly connected to the two limiting screws 14.

[0027] The pressing base 7 has through slots 12 extending outward from the adjusting teeth 11 on both sides. Four moving blocks 9 are fixedly installed on the outer side of the fine-tuning base 8. The lower half of the inner side of the pressing base 7 has a guide slot 10 that is slidably connected to the moving blocks 9. The fine-tuning base 8 is slidably connected to the pressing base 7 through the moving blocks 9, so that the operator can adjust the position of the chip pressed by the fine-tuning base 8 by pushing the fine-tuning base 8. At the same time, the guide slot 10 can not only guide the movement of the fine-tuning base 8, but also press the fine-tuning base 8 through the guide slot 10, so that the fine-tuning base 8 is not easy to shake when clamping and positioning the chip.

[0028] When further positioning of the chip is required, the adjusting gear 11 is rotated so that the adjusting gear 11 can drive the limit screw 14, which is threadedly connected to it, to move up and down. This assists the lower base 7 in limiting the movement of the fine-tuning base 8, thereby further positioning the chip.

[0029] like Figure 1As shown, further, a placement base 2 is provided directly below the fine-tuning base 8 and is fixedly connected to the bottom surface of the clamping machine 1. The placement base 2 is used to place the chip. A fixed platform 3 is fixedly provided on one side of the placement base 2. The fixed platform 3 is rotatably connected to a magnifying glass 6 through a bending rod 4 and a rotating ball 5. When the operator places the chip on the placement base 2, the clamping machine 1 will then position and clamp the chip to be operated so that the chip can be processed. At the same time, the operator can also magnify some details during chip processing through the magnifying glass 6.

[0030] like Figure 1 , Figure 3 As shown, there are two rotating balls 5. One rotating ball 5 is set on the upper part of the fixed platform 3, and an extension rod 401 is connected between the two rotating balls 5. The other rotating ball 5 is connected to the folding rod 4 on one side. The magnifying glass 6 is fixedly set at the end of the folding rod 4 away from the rotating ball 5. The operator can adjust the angle and direction of the magnifying glass 6 through the rotating ball 5, making the use of the magnifying glass 6 more convenient. At the same time, the folding rod 4 can be bent, thereby further increasing the flexibility of the magnifying glass 6.

[0031] like Figure 1 , Figure 3 As shown, further, each of the two rotating balls 5 is fixedly provided with a connecting rod 13 that is rotatably connected to the folding rod 4, the extension rod 401 and the fixed platform 3. The connecting rod 13 can connect the rotating balls 5 with the folding rod 4, the extension rod 401 and the fixed platform 3, thereby achieving the problem solved by one of the above embodiments.

[0032] In this embodiment, as Figures 1-4 As shown, the principle of the chip melting and welding clamping device provided in this embodiment is as follows: the operator can make small adjustments to the pressed chip through the fine adjustment mechanism, so that the position of the chip can be adjusted with the operator so that the operator can process it;

[0033] The fine-tuning base 8 is slidably connected to the pressing base 7 via the moving block 9, so that the operator can adjust the position of the chip pressed by the fine-tuning base 8 by pushing the fine-tuning base 8. At the same time, the guide groove 10 not only provides guidance for the movement of the fine-tuning base 8, but also presses the fine-tuning base 8 through the guide groove 10, so that the fine-tuning base 8 is not easy to shake when clamping and positioning the chip.

[0034] When further positioning of the chip is required, the adjusting gear 11 is rotated so that the adjusting gear 11 can drive the limit screw 14, which is threadedly connected to it, to move up and down. This assists the lower base 7 in limiting the movement of the fine-tuning base 8, thereby further positioning the chip.
