[0027] In order to describe the present invention in detail, a plug removal device of the present invention is described in detail below:

[0028] Please combine Figures 1 to 5 As shown, the utility model provides a plug removal device, including a moving mechanism and a clamping assembly 1. The clamping assembly 1 is movably arranged on the moving mechanism. The clamping assembly 1 has an extended position and a retracted position. The clamping assembly 1 reciprocates between the extended position and the retracted position. The clamping assembly 1 includes a driving member and at least two clamping blocks 101. The driving member is used to drive each clamping block 101 to move toward and away from each other. When each clamping block 101 moves toward each other, an annular clamping portion is formed. Each clamping block 101 has at least a partial annular clamping portion. By providing the clamping assembly 1 with an extended position and a retracted position, when the clamping assembly 1 is in the extended position, the driving member drives each clamping block 101 to move toward each other, forming an annular clamping portion. The annular clamping portion clamps the plug. When the clamping assembly 1 moves from the extended position to the retracted position, it drives the plug on the assembly to leave the assembly, thereby completing the work of removing the plug from the assembly. The plug removal device is efficient in removing plugs, consumes little labor cost, and has good economic promotion value. It should be noted that the clamping direction is the extension direction of the track of the clamping component 1 clamping the assembly part.

[0029] The clamping assembly 1 is connected with the moving mechanism through the first cylinder 103, the clamping assembly 1 is connected with the piston rod of the first cylinder 103, the moving mechanism is connected with the cylinder body of the first cylinder 103, the piston rod of the first cylinder 103 extends along the clamping direction of the clamping assembly 1, when the piston rod of the first cylinder 103 is extended, the clamping assembly 1 is located at the extended position, when the piston rod of the first cylinder 103 is retracted, the clamping assembly 1 is located at the retracted position. The clamping assembly 1 is driven by the first cylinder 103 to reciprocate between the extended position and the retracted position, which is energy-saving, efficient and fast in response. In some embodiments, the clamping assembly 1 can also be connected with the moving mechanism through a linear motor. The connection mode of the clamping assembly 1 and the moving mechanism is adjusted according to the requirements during use.

[0030] The first cylinder 103 is rotationally connected to the moving mechanism, and the rotation axis of the first cylinder 103 is perpendicular to the movement direction of the piston rod of the first cylinder 103. The cylinder body of the first cylinder 103 can be rotationally connected to the moving mechanism through a rotating shaft, and in this embodiment, the rotating shaft is marked with a rotation angle around the axial direction of the rotating shaft, so as to change the clamping direction of the clamping assembly 1 to the plug, so that the plug pulling device can better adapt to different working conditions, and the adaptability of the plug pulling device to the setting angle of the plug is increased.

[0031] In this embodiment, the driving member is a bidirectional cylinder 102, the clamping assembly 1 includes two clamping blocks 101, each clamping block 101 is connected with the output end of the bidirectional cylinder 102, and the bidirectional cylinder 102 drives the two clamping blocks 101 to move towards or away from each other. The bidirectional cylinder 102 can realize the movement of the two clamping blocks 101 towards or away from each other to clamp the plug, and at the same time, the bidirectional cylinder 102 saves installation space and has a relatively low price. In some embodiments, the two clamping blocks 101 can be respectively driven by different first cylinders 103. In other embodiments, the two clamping blocks 101 can be respectively driven to move by a lead screw. The type of driving member can be adjusted according to actual needs.

[0032] The inner wall of the annular clamping part has a clamping surface for clamping the plug, a plurality of barbs extending in the circumferential direction of the inner wall of the annular clamping part are arranged on the clamping surface, and the plurality of barbs are arranged at intervals in the axial direction of the annular clamping part. By arranging the barbs, the annular clamping part can clamp the plug, and the plug can not slip out of the annular clamping part when the plug pulling device is pulled off from the assembled part. At the same time, the barb structure is simple and easy to produce and manufacture.

[0033] The moving mechanism includes a first moving assembly 2, which includes a first sliding rail 202 and a first slider 201 slidably mounted on the first sliding rail. The first cylinder 103 is mounted on the first slider 201, and the first sliding rail 202 extends in a first direction. The first slider 201 slides on the first sliding rail 202 via a first ball screw. The first slider 201 is connected to a nut on the first ball screw, which is sleeved on a first screw rod of the first ball screw. The first screw rod is arranged in a first direction and is connected to a first motor 204. The first motor 204 is used to drive the first screw rod to rotate about its axis, thereby driving the slider connected to the nut to reciprocate in the first direction. The first transport component 2 also includes a first base plate and a first drag chain component 203 for setting the first sliding rail 202. One end of the first drag chain component 203 is connected to the first slider 201, and the other end of the first drag chain component 203 is connected to the first base plate. The first drag chain component 203 is used to protect the wires of the first transport component 2 when the first slider 201 moves on the first sliding rail 202, thereby avoiding serious wear of the wires due to the sliding of the first slider 201 and reducing the number of maintenance times of the first transport component 2.

[0034] The moving mechanism includes a second moving assembly 3, which includes a second sliding track 303 extending in a second direction. The first moving assembly 2 is slidably mounted on the second sliding track 303, with the first direction and the second direction being perpendicular. The first moving assembly 2 slides on the second sliding track 303 via a second ball screw. The first moving assembly 2 is connected to a nut on the second ball screw, which is sleeved onto a second screw rod of the second ball screw. The second screw rod is arranged in the second direction and is connected to a second motor. The second motor is used to drive the second screw rod to rotate about its axis, thereby driving the first moving assembly 2, which is connected to the nut, to reciprocate in the second direction. The second transport component 3 also includes a second base plate 304 and a second drag chain component 302 for setting the second sliding rail 303. One end of the second drag chain component 302 is connected to the first transport component 2, and the other end of the second drag chain component 302 is connected to the second base plate 304. The second drag chain component 302 is used to protect the wires of the second transport component 3 when the first transport component 2 moves on the second sliding rail 303, thereby avoiding serious wear of the wires due to the sliding of the second transport component 3 and reducing the number of maintenance times of the second transport component 3.

[0035] The moving mechanism further includes a third transport assembly 4, which includes a third sliding track 404 extending in a third direction. The second transport assembly 3 is slidably mounted on the third sliding track 404, with the third direction being perpendicular to both the first and second directions. The second transport assembly 3 slides on the third sliding track 404 via a third ball screw. The second transport assembly 3 is connected to a nut on the third ball screw, which is mounted on a third screw of the third ball screw. The third screw is arranged in the third direction and is connected to a third motor 401. The third motor 401 is configured to drive the third screw to rotate about its axis, thereby driving the second transport assembly 3, which is connected to the nut, to reciprocate in the third direction. The third transport assembly 4 also includes a third base plate 405 for mounting a third sliding track 404 and a third drag chain assembly 403. One end of the third drag chain assembly 403 is connected to the second transport assembly 3, and the other end of the third drag chain assembly 403 is connected to the third base plate 405. The third drag chain assembly 403 is used to protect the wires of the third transport assembly 4 when the second transport assembly 3 moves on the third sliding track 404, preventing severe wear of the wires due to the sliding of the third transport assembly 4, thereby reducing the need for maintenance of the third transport assembly 4. The third transport assembly 4 also includes a limiting track 402 arranged along the third direction. The limiting track 402 is used to limit the movement direction of the second transport assembly 3. The second transport assembly 3 includes a clamping block 301 that engages with the limiting track 402. The clamping block 301 is disposed on the second base plate 304. The third transport assembly 4 is connected to the base 6.

[0036] In some embodiments, the first transport assembly 2, the second transport assembly 3 and the third transport assembly 4 can all be moved by the first cylinder 103 or belt motion. The way the first transport assembly 2, the first transport assembly 2 and the second transport assembly 3 move can be adjusted according to actual needs.

[0037] By setting the first moving component 2, the second moving component 3 and the third moving component 4, the position options for removing the plug of the plug removal device can be increased to meet the requirements of removing the plug at different positions of different assemblies, thereby improving the adaptability of the plug removal device to different working conditions and having better practicality.

[0038] like Figure 2 As shown, the clamping assembly 1 includes two clamping blocks 101. When the two clamping blocks 101 are close together, two annular clamping portions are formed. In this embodiment, the two annular clamping portions are formed by the two clamping blocks 101, so that the two annular clamping portions can share a driving member, thereby reducing the manufacturing cost of the plug removal device.

[0039] Among them, the plug removal device also includes a base 6 and a clamping assembly 7 for clamping the assembly. The clamping assembly 7 and the moving mechanism are both arranged on the base 6. The base 6 has a placement position for placing the assembly. The clamping assembly 7 is arranged corresponding to the placement position. The clamping assembly 7 includes a support part 702 and a clamping part 701 arranged on the support part 702 for sliding along the first direction. The clamping part 701 has a clamping position and a release position. The clamping part 701 reciprocates between the clamping position and the release position. When the clamping part 701 is in the clamping position, the clamping part 701 clamps the assembly. When the clamping part 701 is in the release position, the clamping part 701 leaves the assembly. The clamping part 701 can realize reciprocating motion along the first direction through a ball screw, a cylinder or a linear motor. The clamping portion 701 is elongated, and the portion of the clamping portion 701 that contacts the assembly is provided with anti-slip rubber. The anti-slip rubber is provided with multiple anti-slip strips extending along the width of the clamping portion 701. These strips are spaced apart along the length of the clamping portion 701, or the anti-slip rubber is provided with multiple anti-slip protrusions that protrude toward the placement position. The provision of the anti-slip rubber prevents bumps or scratches on the assembly during the clamping process, protecting the assembly. The provision of the anti-slip strips and anti-slip protrusions ensures that the clamping assembly 7 maintains its grip on the assembly.

[0040] In this embodiment, a conveying track 5 extending along the third direction is provided on the base 6 corresponding to the placement position, and chains are provided on both sides of the conveying track 5 for transmission. The space between the two chains is hollow, and a lifting mechanism is provided corresponding to the placement position. The assembly parts placed on the tray 8 are transported on the conveying track 5. When the tray 8 reaches the placement position, the lifting mechanism of the conveying track 5 lifts the tray 8 and detaches it from the conveying track 5, so that the assembly parts are located in the placement position, so that the plug pulling device can pull out the plug on the assembly parts.

[0041] In summary, by providing a clamping assembly 1 with an extended position and a retracted position, when the clamping assembly 1 is in the extended position, the driving member drives the clamping blocks 101 toward each other to form an annular clamping portion, which clamps the plug. When the clamping assembly 1 reaches the retracted position from the extended position, it drives the plug on the assembly part away from the assembly part, completing the work of removing the plug from the assembly part. Removing the plug using the plug removal device is highly efficient, consumes little labor cost, and has good economic promotion value.
