[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme that satisfies both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in the field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0047] In order to prevent spring probes from being damaged during transportation or storage, a protective cover is usually installed on the probe, and the protective cover can be removed when in use. However, for different types of spring probes, due to their different use locations and welding methods, there are different requirements for the holding force of the protective cover. Employees are very likely to feel fatigued when holding a protective cover with a large holding force for a long time, and there is a risk of damaging the electrical components on the circuit board when operators manually hold the protective cover.

[0048] Based on this, the present invention proposes a protective cover disassembly device, which comprises a placement plate and a movable plate, and the movable plate is provided with a clamp that can extend into a slide groove of the placement plate. By pressing the movable plate in a direction away from the placement plate, the protective cover is clamped in the clamp and forced to separate from the spring probe, thereby completing the disassembly of the protective cover, and the circuit board can be removed to proceed to the next step.

[0049] like Figure 1-8As shown, the protective cover 30 disassembly device includes a mounting seat 100, a placement plate 200, a movable plate 300 and an elastic component 400, wherein a cavity is formed inside the mounting seat 100 and an opening is provided which is connected to the cavity; the placement plate 200 is detachably arranged at the opening, and a slide groove 210 is provided on the placement plate 200; the movable plate 300 is movably arranged in the cavity and arranged on one side of the placement plate 200, and a clamp 310 is provided on the side of the movable plate 300 close to the placement plate 200 , and the clamp 310 extends into the slide groove 210; the elastic component 400 is arranged in the cavity and connected to the movable plate 300, so that the movable plate 300 has a tendency to move toward the placement plate 200; the circuit board 10 slides along the placement plate 200, so that the spring probe 20 with the protective cover 30 slides along the slide groove 210 into the clamp 310; the movable plate 300 is pressed in the direction away from the placement plate 200, so that the protective cover 30 and the spring probe 20 are separated.

[0050] In the technical solution adopted in this embodiment, a mounting seat 100 is provided in the device, a cavity is formed inside the mounting seat 100, and an opening connected to the cavity is provided, and a placement plate 200 is detachably provided at the opening, a slide groove 210 is provided on the placement plate 200, and a movable plate 300 movably provided in the cavity is provided, and a clamp 310 that can extend into the slide groove 210 is provided on the movable plate 300; in the process of removing the protective cover 30 from the spring probe 20 on the circuit board 10, the circuit board 10 is firstly placed upside down on the placement plate 200. Then slide the circuit board 10 along the placement plate 200 according to the preset trajectory, so that the spring probe 20 can accurately slide from one side of the clamp 310 to the inside of the clamp 310, ensuring that the protective cover 30 can be accurately fixed in the clamp 310; then press the movable plate 300 in the direction away from the placement plate 200, so that the protective cover 30 is separated from the spring probe 20 under the traction of the clamp 310, and the batch disassembly process of the spring probe 20 and the protective cover 30 can be successfully completed, and the circuit board 10 can be removed to proceed to the next step. In addition, in order to facilitate the resetting of the movable plate 300 after being pressed, an elastic component 400 connected to the movable plate 300 can also be provided in the cavity. When the movable plate 300 is pressed, the spring component will be compressed. After the pressing force on the movable plate 300 disappears, the movable plate 300 can be restored to its original position under the elastic force of the spring component. The device has a simple structure and is easy to operate, and can effectively improve the disassembly efficiency of the protective cover 30.

[0051] Specifically, the shapes and materials of the mounting base 100, the placement plate 200 and the movable plate 300 are not specifically limited. It should be pointed out that the clamping space of the clamp 310 should be smaller than the outer diameter of the protective cover 30. Therefore, in the process of fixing the protective cover 30 to the clamp 310, it is necessary to first place the protective cover 30 in the slide groove 210 of the placement plate 200, slide along the slide groove 210 to one side of the clamp 310, and then slide into the inside of the clamp 310, rather than placing the protective cover 30 directly above the clamp 310 and inserting it into the clamp 310 from top to bottom. In this way, the protective cover 30 will not slip out of the clamp 310 during the movement of the movable plate 300 away from the placement plate 200, resulting in the inability to complete the separation of the protective cover 30 and the spring probe 20. Preferably, in order to ensure that the spring probe 20 on the circuit board 10 can be accurately positioned in the clamp 310, preferably, a side wall of the placement plate 200 is arranged to protrude from the upper surface, thereby limiting the sliding displacement of the circuit board 10 along the placement plate 200. It should be explained that a plurality of clamps 310 should be arranged at intervals, and preferably, the arrangement positions and numbers of the plurality of clamps 310 on the movable plate 300 should correspond one-to-one to the arrangement positions and numbers of the spring probes 20 on the circuit board 10.

[0052] For example, Figure 6 and 7 As shown, in one embodiment of the present invention, the clamp 310 includes:

[0053] A clamping arm 311, wherein two clamping arms 311 are provided at intervals, and the two clamping arms 311 are arranged opposite to each other to form a receiving space therebetween; and

[0054] A clamp 313 is provided for each clamp arm 311. The two clamps 313 extend toward each other without contacting each other to form a clamping space. The clamping space is connected to the accommodating space. The protective cover 30 passes through the clamping space and is arranged in the accommodating space. The two clamps 313 are clamped on two opposite sides of the protective cover 30.

[0055] Specifically, in order to facilitate the fixation of the protective cover 30, the clamp 310 is configured as a clamp arm 311 and a clamp head 313. Preferably, the clamp arm 311 and the clamp head 313 are bent and connected, and the two clamp heads 313 extend in a direction close to each other without contacting each other to form a clamping space. The protective cover 30 passes through the clamping space and is arranged in the accommodating space. The two clamp heads 313 are respectively clamped on the opposite sides of the protective cover 30, so that when the movable plate 300 moves in a direction away from the placement plate 200, the clamp 310 clamps the protective cover 30 and moves synchronously, so that the protective cover 30 and the spring probe 20 are forced to separate. After separation, the protective cover 30 remains in the accommodating space.

[0056] For example, Figure 6 and 7As shown, in one embodiment of the present invention, a through hole 320 is further provided on the movable plate 300, and two clamping arms 311 are respectively provided on opposite sides of the opening of the through hole 320, so that the through hole 320 is connected to the accommodating space. In order to clean the protective cover 30 in the accommodating space in time, a through hole 320 connected to the accommodating space can also be provided on the movable plate 300, and by vibrating the movable plate 300, the removed protective cover 30 can fall from the accommodating space through the through hole 320 into the cavity of the mounting seat 100, without hindering the movable plate 300 from performing the next step of removing the protective cover 30.

[0057] For example, Figure 3 and 4 As shown, in one embodiment of the present invention, the protective cover 30 includes:

[0058] A connecting portion 31 detachably connected to the spring probe 20 ; and

[0059] The head portion 33 extends along the axial direction of the connecting portion 31 toward a side away from the spring probe 20 , and the outer diameter width of the head portion 33 is greater than the distance between the two clamps 313 .

[0060] Specifically, the protective cover 30 is divided into a connecting portion 31 and a head portion 33, wherein the connecting portion 31 extends along the axial direction of the head portion 33, and the connecting portion 31 and the spring probe 20 are detachably connected, and the specific detachable connection method is not specifically limited, for example, it can be a snap connection, a plug connection, etc. It should be pointed out that the outer diameter of the head portion 33 needs to be larger than the distance between the two clamps 313 to ensure that the protective cover 30 will not pass out of the clamping space and be pulled off during the movement of the movable plate 300. The outer diameter of the connecting portion 31 is equal to the distance between the two clamps 313 to ensure that the clamps 313 can just clamp the connecting portion 31.

[0061] For example, Figure 1 As shown, in one embodiment of the present invention, the mounting base 100 includes:

[0062] A support plate 110, wherein two support plates 110 are arranged opposite to each other, and the two support plates 110 are supported on the edge of the placement plate 200; and

[0063] The bottom plate 120 is disposed on a side of the support plate 110 away from the placement plate 200 , and is fixedly connected to the support plate 110 .

[0064] Specifically, the mounting base 100 may include a bottom plate 120 and two supporting plates 110, a cavity is formed between the bottom plate 120 and the two supporting plates 110 that are arranged opposite to each other, and an opening is formed between the two supporting plates 110, and the placement plate 200 is fixedly arranged at the opening. When the movable plate 300 separates the protective cover 30 from the spring probe 20, the protective cover 30 can fall from the through hole 320 to the bottom plate 120 for collection, so as to prevent the protective cover 30 from falling in all directions.

[0065] For example, Figure 1 As shown, in one embodiment of the present invention, the elastic component 400 includes:

[0066] A fixed column 410, which is disposed on one side of the bottom plate 120 close to the movable plate 300; and

[0067] The elastic body 420 has one end disposed inside the fixing column 410 , and the other end protruding from the fixing column 410 and connected to the movable plate 300 .

[0068] Specifically, the elastic component 400 may include a fixed column 410 and an elastic body 420. The shape of the fixed column 410 is not specifically limited, as long as there is a space inside to accommodate the elastic body 420. Similarly, the type of the elastic body 420 is not specifically limited, for example, it can be a spring, or it can be a foam, etc., as long as it is an elastic body 420 with resilience. The fixed column 410 is arranged on the bottom plate 120, and one end of the elastic body 420 is fixed inside the fixed column 410, and the other end extends and protrudes outside the fixed column 410 and is connected to the movable plate 300.

[0069] For example, Figure 8 As shown, in one embodiment of the present invention, the protective cover 30 disassembly device further includes a limit assembly 500, which connects the movable plate 300 and the support plate 110 to limit the sliding stroke of the movable plate 300 along the support plate 110. In order to limit the sliding stroke of the movable plate 300 along the support plate 110, the limit assembly 500 may also be provided, so that the sliding displacement length of the movable plate 300 along the support plate 110 should be at least greater than the length of the protective cover 30 on the spring probe 20, thereby ensuring that the clamp 310 can separate the protective cover 30 from the spring probe 20.

[0070] For example, Figure 8 As shown, in one embodiment of the present invention, the limiting assembly 500 includes:

[0071] A limiting protrusion 510, which is disposed on a side of the movable plate 300 close to the supporting plate 110; and

[0072] The limiting groove 520 is disposed on a side of the support plate 110 close to the movable plate 300 , and the limiting protrusion 510 is slidably disposed in the limiting groove 520 .

[0073] Specifically, in order to ensure that the movable plate 300 can slide smoothly along the support plate 110, the limiting assembly 500 is divided into a limiting protrusion 510 and a limiting groove 520. Preferably, the movable plate 300 is provided with a limiting protrusion 510, and the support plate 110 is provided with a limiting groove 520. Of course, in other embodiments, the limiting protrusion 510 can also be provided on the support plate 110, and the limiting groove 520 can be provided on the movable plate 300. It should be noted that the shapes of the limiting protrusion 510 and the limiting groove 520 are not specifically limited, as long as the shape of the limiting protrusion 510 and the limiting groove 520 are compatible, it can be ensured that the movable plate 300 can slide smoothly along the support plate 110.

[0074] For example, Figure 5 As shown, in one embodiment of the present invention, a placement groove 220 is further provided on the placement plate 200, and the placement groove 220 is communicated with the slide groove 210, and the circuit board 10 slides along a preset track in the placement groove 220. In order to facilitate the circuit board 10 to slide along the placement plate 200, a placement groove 220 may be provided on a side of the placement plate 200 away from the cavity, so that the placement plate 200 slides along the placement groove 220.

[0075] For example, Figure 5 As shown, in one embodiment of the present invention, the placement plate 200 is further provided with a notch 230, which is provided at the edge of the placement plate 200 and communicates with the placement groove 220. After the protective cover 30 is removed from the spring probe 20, in order to facilitate the separation of the circuit board 10 and the placement plate 200, a notch 230 may be further provided on the placement plate 200, and the user may grasp the edge of the circuit board 10 at the notch 230 and easily remove the circuit board 10.

[0076] The above descriptions are only optional embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent structural changes made using the contents of the present invention's specification and drawings, or directly / indirectly applied in other related technical fields, are included in the patent protection scope of the present invention.
