Description

Technical Field

[0001] This utility model relates to the field of electronic device processing technology, and more specifically, to a rework clamping device for electronic components. Background Technology

[0002] Soldering of electronic components, especially PCB boards and chips, can lead to soldering defects. For example, after reflow and wave soldering processes, circuit boards may exhibit issues such as cold solder joints, short circuits, crosslinks, wetting, component displacement, and tombstoning. These soldering problems all affect product quality, so after quality inspection, these issues need to be repaired by employees. With industry development, many repair tools have emerged, such as chip rework stations, X-ray machines, high-powered microscopes, hot air guns, and soldering irons. Repair personnel can use one or more of these tools to repair defective solder joints. Among these desoldering tools, the hot air gun is a frequently used and widely applicable heating desoldering tool. When using a hot air gun to desolder electronic components, the components need to be positioned using clamps, and high-temperature resistant heat-insulating tape should be applied to non-heated areas of the components for protection during the heating process. Existing fixtures for positioning electronic components have poor versatility, and the application of high-temperature resistant heat-insulating tape lacks standardization. Once the component melts, the tape can easily disturb the component, causing misalignment or damage.

[0003] Therefore, there is an urgent need for an electronic component fixture that can both position electronic components and provide thermal insulation. Utility Model Content

[0025] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model. Example 1

[0026] like Figure 1-6 As shown, an electronic component rework clamping device includes a shielding member 1 and two sets of clamping mechanisms 2. Each clamping mechanism 2 includes a first clamping member 21, a second clamping member 22, and a driving member 23 that drives the first clamping member 21 and the second clamping member 22 to approach or move away from each other. The shielding member 1 covers the electronic component positioned between the first clamping member 21 and the second clamping member 22, blocking and conducting external heat. The electronic components used in this technical solution are PCB boards and chips, but are not limited to PCB boards and chips. The driving member 23 drives the first clamping member 21 and the second clamping member 22 to approach or move away from each other, thus adjusting the distance between the first clamping member 21 and the second clamping member 22 according to the size of different electronic components. This allows the device to be applied to electronic components of different sizes, increasing its application range. The shielding member 1 can cover the non-heated area of ​​the electronic component as needed. The shielding member 1 is usually made of a material with excellent thermal conductivity, such as metal, to quickly conduct the heat generated during the rework operation to the air or structural components, better protecting the non-heated area.

[0027] Each clamping mechanism 2 has a plurality of first grippers 211 on the side of the first clamping member 21 facing the second clamping member 22, and a plurality of second grippers 221 on the side of the second clamping member 22 facing the first clamping member 21. The first grippers 211 and the second grippers 221 are configured to cooperate one-to-one. The first grippers 211 and the second grippers 221 configured to cooperate one-to-one are usually used to clamp flexible electronic components such as PCB boards. The second clamping members 22 on both clamping mechanisms 2 are provided with second chip slots 222. The second chip slots 222 on both clamping mechanisms 2 are configured to cooperate one-to-one. The second chip slots 222 configured to cooperate one-to-one are used to clamp electronic components with regular shapes such as chips.

[0028] The first gripper 211 is provided with a first placement opening 2111, and the second gripper 221 is provided with a second placement opening 2211. The first placement opening 2111 and the second placement opening 2211 are arranged in parallel. The first placement opening 2111 and the second placement opening 2211 are used to place the ends of electronic components such as PCB boards, so as to prevent the PCB boards from falling off the rework clamping device during the rework process.

[0029] The driving component 23 includes a main frame 231, a screw 232, and a movable block 233. The screw 232 and the movable block 233 are threadedly engaged. A first clamping member 21 and a second clamping member 22 are mounted on the main frame 231. The movable block 233 is connected to either the first clamping member 21 or the second clamping member 22. Since the driving component 23 simultaneously drives two sets of clamping mechanisms 2, both sets of clamping mechanisms 2 are mounted on the main frame 231. Each set of clamping mechanisms 2 includes a component that engages with the screw 232. The movable block 233 and two sets of clamping mechanisms 2 are arranged along the length of the screw 232. The threads of the screw 232 and the two movable blocks 233 are opposite. The first clamping member 21 is fixedly set on the main frame 231. The second clamping member 22 is connected to the screw 232 through the movable block 233. When the screw 232 is rotated, the second clamping member 22 moves away from or closer to the first clamping member 21, thereby achieving the effect of adjusting the first clamping member 21 and the second clamping member 22 to adapt to electronic components of different sizes.

[0030] The main frame 231 is a rectangular frame, and the screw 232 passes through the main frame 231 from one end. The screw 232 is provided with a rotational torque 234 at one end outside the main frame 231. The first clamping member 21 or the second clamping member 22 moves back and forth along the length of the screw 232.

[0031] The second clamping member 22 includes a clamping body 223 and a buffer body 224. A buffer 225 is provided between the clamping body 223 and the buffer body 224. Limiting blocks 2231 are provided on both sides of the clamping body 223. The limiting blocks 2231 move close to the main frame 231.

[0032] The clamping body 223 has a clamping mounting groove 2232 on one side, and the buffer body 224 has a clamping sliding block 2241 on one side. The clamping sliding block 2241 is slidably disposed in the clamping mounting groove 2232. The buffer 224 can be an elastic element such as a spring or a rubber block.

[0033] The clamping sliding block 2241 is provided with a plurality of buffer mounting grooves 2242 on the side facing the clamping mounting groove 2232, and the buffer member 225 is disposed in the buffer mounting groove 2242.

[0034] It also includes an operation panel 3, a heat-conducting frame 4, and a movable arm 11. The heat-conducting frame 4 and the movable arm 11 are mounted on the operation panel 3, and the main frame 231 is mounted on the heat-conducting frame 4. The heat-conducting frame 4 conducts heat from the main frame 231 to the operation panel 3. The movable arm 11 is connected to the shielding component 1 and can conduct heat from the shielding component 1 to the operation panel 3. The movable arm 11 can be bent into the desired shape as needed. One side of the shielding component 1 is connected to the shielding cavity 12. The operation panel 3 is not only used to install the heat-conducting frame 4 and the movable arm 11, but also to absorb and conduct heat generated during the repair process. The movable arm 11 is composed of movable hinges and can be bent into any desired shape to cover the shielding component 1 in a suitable position, ensuring that the shielding component 1 can cover the surface of any of the clamping mechanisms 2, thus fully protecting the electronic components being repaired.

[0035] A rotating connector 5 is provided between the movable arm 11 and the shielding component 1. The rotating connector 5 includes an upper balloon 51, a lower balloon 52, and a connecting rod 53. The movable arm 11 is connected to the lower balloon 52. One end of the connecting rod 53 is connected to the shielding component 1, and the other end of the connecting rod 53 is located between the upper balloon 51 and the lower balloon 52. The upper balloon 51 and the lower balloon 52 are configured to cooperate with each other. A ball 54 is provided at the end of the connecting rod 53 located between the upper balloon 51 and the lower balloon 52. The ball 54 is rotatably positioned between the upper balloon 51 and the lower balloon 52. Example 2

[0036] like Figure 7 As shown, an electronic component rework clamping device is provided. The first clamping member 21 is provided with a plurality of first clamping claws 211 and a plurality of first chip slots 212; the second clamping member 22 is provided with a plurality of second clamping claws 221 and a plurality of second chip slots 222; the first clamping claws 211 and the second clamping claws 221 are configured to cooperate in a one-to-one correspondence, and the first chip slots 212 and the second chip slots 222 are configured to cooperate in a one-to-one correspondence. The difference between Embodiment 2 and Embodiment 1 is that the first clamping member 21 is provided with both the first clamping claws 211 and the first chip slots 212, and the second clamping member 22 is also provided with second chip slots 222 on the side facing the first clamping member 21. In this case, the chip can also be placed on the first clamping member 21 and the second clamping member 22 in a set of clamping mechanisms 2.

[0037] Similarly, as needed, it is entirely possible to adopt the same method on both sets of clamping mechanisms 2. Figure 7 The structure described above can also use only one set of clamping mechanisms 2, and all the above-mentioned modifications are within the protection scheme of this technical solution.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
