Figure 5 This is a schematic diagram of the structure of the fixing seat in a cover-removing fixture provided in an embodiment of this utility model. Figure 6 This is a schematic diagram of the structure of a cap-removing fixture provided in an embodiment of the present invention. The cap-removing fixture provided in this embodiment of the present invention includes a driving assembly 2, a clamping mechanism 3, and a fixed base 1. The fixed base 1 has a clamping groove 11, and is provided with a first clearance groove 12 and a second clearance groove 13 respectively communicating with the clamping groove 11. The first clearance groove 12 and the second clearance groove 13 are arranged opposite to each other. The driving assembly 2 includes a first gripping part 21, a second gripping part 22, a first handle 23, and a second handle 24. The first gripping part 21 and the second gripping part 22 are arranged at intervals. The first handle 23 is connected to the first gripping part 21, and the second handle 24 is connected to the second gripping part 22. The second handle 24 and the first handle 23 are hinged to each other via a pivot 25. The clamping mechanism 3 includes at least a first clamping seat 31 and a second clamping seat 32. The first clamping member 33 and the second clamping member 34 are arranged opposite to each other. The first clamping member 31 is connected to the first handle 23, and the second clamping member 32 is connected to the second handle 24. The first clamping member 33 is fixed on the first clamping member 31, and the second clamping member 34 is fixed on the second clamping member 32. When the first gripping part 21 and the second gripping part 22 approach each other, the first handle 23 drives the first clamping member 31 with the pivot 25 as the fulcrum, so that the first clamping member 33 enters the clamping groove 11 along the through direction of the first clearance groove 12, and the second handle 24 drives the second clamping member 32, so that the second clamping member 34 enters the clamping groove 11 along the through direction of the second clearance groove 13.

[0032] The clamping groove 11 of the fixing base 1 has space to accommodate the material cover 5. The snap-fit ​​connector 51 on the material cover 5 matches the snap-fit ​​groove 41 on the material tube 4. By snapping the snap-fit ​​connector 51 into the snap-fit ​​groove 41, the material cover 5 and the material tube 4 can be connected to each other. By applying pressure to the snap-fit ​​connector 51 located in the snap-fit ​​groove 41 and pressing the snap-fit ​​connector 51 toward the inside of the material tube 4, the material cover 5 and the material tube 4 can be separated. For example, the cross-section of the material tube 4 can be rectangular. A snap-fit ​​groove 41 is provided on the upper part of the material tube 4, and a snap-fit ​​connector 51 is snapped into the inside of the snap-fit ​​groove 41. Another snap-fit ​​groove 41 is provided on the lower part of the material tube 4, and another snap-fit ​​connector 51 is snapped into the inside of the snap-fit ​​groove 41, so that the two snap-fit ​​connectors 51 fix the material cover 5 to the material tube 4. The first clearance groove 12 on the fixed base 1 can be matched with the aforementioned slot 41, and the second clearance groove 13 on the fixed base 1 can be matched with the aforementioned slot 41. That is, when the fixed base 1 is sleeved on the material cover 5 located on the material tube 4, the aforementioned slot 41 located in the clamping groove 11 is directly opposite the first clearance groove 12, and the aforementioned slot 41 is directly opposite the second clearance groove 13. After the first clamping member 33 enters the clamping groove 11 along the through direction of the first clearance groove 12, the first clamping member 33 will contact a locking connector 51 located in the aforementioned slot 41 and apply pressure to the locking connector 51. After the second clamping member 34 enters the clamping groove 11 along the through direction of the second clearance groove 13, the second clamping member 34 will contact another locking connector 51 located in the aforementioned slot 41 and apply pressure to the other locking connector 51, thereby pushing the locking connector 51 out of the corresponding slot 41 and quickly separating the material cover 5 and the material tube 4.

[0033] When the operator applies force to bring the first gripping part 21 and the second gripping part 22 closer together, the driving force causes the first handle 23 to rotate around the pivot 25. This displacement causes the first clamping seat 31 connected to the first handle 23 and the first clamping member 33 fixed to the first clamping seat 31 to move, allowing the first clamping member 33 to enter the clamping groove 11 along the first clearance groove 12. Simultaneously, the second handle 24 rotates around the pivot 25, causing the second clamping seat 32 connected to the second handle 24 and the second clamping member 34 fixed to the second clamping seat 32 to move, allowing the second clamping member 34 to enter the clamping groove 11 along the second clearance groove 13. The clamping groove 11 of the fixed seat 1 accommodates and positions the joint of the material cover 5 and the material tube 4 to be operated, so that the first clamping member 33 and the second clamping member 34 can simultaneously contact the clamping connector 51 on the material tube 4 corresponding to the clamping groove 41 in the clamping groove 11. After the clamping connector 51 is disengaged from the corresponding clamping groove 41, the first gripping part 21 and the second gripping part 22 are pulled in a direction away from the material tube 4, so that the material cover 5 separated from the material tube 4 can be quickly removed.

[0034] In this embodiment, the first gripping part 21 in the driving assembly 2 is connected to the first handle 23, and the second gripping part 22 is connected to the second handle 24. The second handle 24 and the first handle 23 are hinged to each other by a rotating shaft 25. The first clamping seat 31 and the second clamping seat 32 in the clamping mechanism 3 are arranged opposite to each other. The first clamping seat 31 is connected to the first handle 23, and the second clamping seat 32 is connected to the second handle 24. The first pressing member 33 is fixed on the first clamping seat 31, and the second pressing member 34 is fixed on the second clamping seat 32. When the first gripping part 21 and the second gripping part 22 approach each other, the first handle 23 drives the first clamping seat 31 with the rotating shaft 25 as the fulcrum, so that the first pressing member 33 enters the clamping groove 11 along the through direction of the first clearance groove 12 on the fixed seat 1, and the second handle 24 drives the second clamping seat 32, so that the second pressing member 34 enters the clamping groove 11 along the through direction of the second clearance groove 13 on the fixed seat 1. In this way, when the first gripping part 21 and the second gripping part 22 are gripped together, the first handle 23 and the second handle 24 will rotate relative to each other around the pivot 25, causing the first clamping seat 31 and the second clamping seat 32 to move closer together. At this time, the first pressing member 33 enters the clamping groove 11 along the first clearance groove 12 and inserts into the corresponding slot 41 on the material tube 4 to press the snap-fit ​​connector 51 located in the slot 41, causing the snap-fit ​​connector 51 to disengage from the slot 41. At the same time, the second pressing member 34 enters the clamping groove 11 along the second clearance groove 13 and inserts into the corresponding slot 41 on the material tube 4 to press the snap-fit ​​connector 51 located in the slot 41, causing the snap-fit ​​connector 51 to disengage from the slot 41, thus achieving rapid separation of the material cap 5 and the material tube 4. This achieves the technical effect of improving the convenience of operation and increasing efficiency during the cap removal process.

[0035] In one embodiment, the clamping mechanism 3 in the cap removal fixture provided by this utility model further includes a first elastic reset member 35 and a second elastic reset member 36. The first elastic reset member 35 is fixed on the first clamping seat 31, and the second elastic reset member 36 is fixed on the second clamping seat 32. The first elastic reset member 35 and the second elastic reset member 36 respectively abut against the fixed seat 1. The clamping groove 11 is located between the first elastic reset member 35 and the second elastic reset member 36. The first elastic reset member 35 and the second elastic reset member 36 can each refer to a spring. After the cap removal operation, when the operator releases the gripping force applied to the first gripping part 21 and the second gripping part 22, the first elastic reset member 35 and the second elastic reset member 36 restore their deformation due to their own elasticity. At this time, the first elastic reset member 35 pushes the first clamping seat 31 away from the fixed seat 1, causing the first pressing member 33 to exit the clamping groove 11 along the through direction of the first clearance groove 12. At the same time, the second elastic reset member 36 pushes the second clamping seat 32 away from the fixed seat 1, causing the second pressing member 34 to exit the clamping groove 11 along the through direction of the second clearance groove 13. Without additional operation, the first clamping seat 31 and the second clamping seat 32 can be restored to the initial open state. Through the quick automatic reset function, the operation steps can be reduced and the efficiency of the cap removal operation can be improved.

[0036] In some embodiments, the fixing base 1 is further provided with a first guide hole 14 and a second guide hole 15, the first guide hole 14 and the second guide hole 15 respectively communicating with the clamping groove 11. The clamping mechanism 3 in the cover removal fixture provided in this utility model embodiment also includes a first linear bearing 37, a first guide rod 371, a second linear bearing 38 and a second guide rod 381. The first linear bearing 37 is sleeved on the first guide rod 371 and is installed on the first clamping base 31. The first guide rod 371 passes through the first guide hole 14. The second linear bearing 38 is sleeved on the second guide rod 381 and is installed on the second clamping base 32. The second guide rod 381 passes through the second guide hole 15. When the operator grips the first gripping part 21 and the second gripping part 22, respectively driving the first clamping seat 31 and the second clamping seat 32 to move towards each other, the first guide rod 371 moves linearly along the first guide hole 14 under the constraint of the first linear bearing 37, while the second guide rod 381 moves linearly along the second guide hole 15 under the constraint of the second linear bearing 38. This restricts the movement paths of the first clamping seat 31, the first clamping member 33 located on the first clamping seat 31, the second clamping seat 32, and the second clamping member 34 located on the second clamping seat 32 to a predetermined linear trajectory. This helps eliminate radial swaying or offset during movement, improves the accuracy of the first clamping member 33 entering the clamping groove 11 along the first clearance groove 12 and inserting the first clamping member 33 into the corresponding slot 41, and also improves the accuracy of the second clamping member 34 entering the clamping groove 11 along the second clearance groove 13 and inserting the second clamping member 34 into the corresponding slot 41. This allows the first clamping member 33 and the second clamping member 34 to reliably clamp the corresponding card connector 51, disengaging the card connector 51 from the slot 41, reducing operational errors or ineffective actions, and improving the reliability, convenience, and work efficiency of the cap removal operation.

[0037] In some embodiments, a first limiting part 372 is provided on the first guide rod 371, and the projection of the first limiting part 372 on the first guide hole 14 along the direction close to the first guide hole 14 is at least partially located outside the first guide hole 14. A second limiting part 382 is provided on the second guide rod 381, and the projection of the second limiting part 382 on the second guide hole 15 along the direction close to the second guide hole 15 is at least partially located outside the second guide hole 15. When the first clamping seat 31 drives the first guide rod 371 to move into the clamping groove 11 to a predetermined position, the first limiting part 372 will come into contact with or interfere with the fixing seat 1 structure around the first guide hole 14, thereby preventing the first guide rod 371, as well as the first clamping seat 31 and the first clamping member 33, from moving further into the clamping groove 11. Simultaneously, when the second clamping seat 32 drives the second guide rod 381 to move into the clamping groove 11 to a predetermined position, the second limiting part 382 and the fixed seat 1 structure around the second guide hole 15 will come into contact with each other or interfere with each other, thereby preventing the second guide rod 381, as well as the second clamping seat 32 and the second clamping member 34, from moving further into the clamping groove 11. This can prevent excessive movement of the first clamping seat 31, the second clamping seat 32, the first clamping member 33 and the second clamping member 34, which could lead to jamming, damage to parts, or damage caused by excessive pressure on the material cover 5 and the material tube 4. It can also enable the first clamping member 33 and the second clamping member 34 to move to the preset working position and reliably press into the corresponding slot 41 to perform the cap removal action, avoiding failure caused by insufficient or excessive stroke, and improving the reliability and consistency of each operation.

[0038] In some embodiments, when the first gripping part 21 and the second gripping part 22 release the pressure applied to the first clamping seat 31 and the second clamping seat 32, the first elastic reset member 35 restores its deformation to push the first clamping seat 31 to move the first guide rod 371 away from the first guide hole 14, and the second elastic reset member 36 restores its deformation to push the second clamping seat 32 to move the second guide rod 381 away from the second guide hole 15. After the cap removal action is completed, the pressure release triggers automatic reset. The first elastic reset member 35 drives the first clamping seat 31 to retract, and through the guidance of the first linear bearing 37 and the first guide rod 371, drives the first clamping member 33 to quickly and smoothly exit the clamping groove 11 and the corresponding slot 41 along a straight path. At the same time, the second elastic reset member 36 synchronously drives the second clamping seat 32 to retract, thereby driving the second clamping member 34 to exit the clamping groove 11 and the corresponding slot 41, so that the entire fixture can be immediately prepared for the next operation without manual adjustment, which can shorten the operation cycle time and improve the convenience and efficiency of continuous operation.

[0039] In some embodiments, the fixing base 1 of the cap removal fixture provided by this utility model includes a first support plate 16, a second support plate 17, and a back support plate 18. The first support plate 16, the second support plate 17, and the back support plate 18 can be integrally formed. The first support plate 16 and the second support plate 17 are arranged opposite to each other. The back support plate 18 is connected to the first support plate 16 and the second support plate 17 respectively. The first support plate 16, the second support plate 17, and the back support plate 18 enclose the clamping groove 11. The first clearance groove 12 and the first guide hole 14 are respectively provided on the first support plate 16. The second clearance groove 13 and the second guide hole 15 are respectively provided on the second support plate 17. By machining the first clearance groove 12 and the first guide hole 14 onto the first support plate 16, and the second clearance groove 13 and the second guide hole 15 onto the second support plate 17, the relative positions of the first clearance groove 12 and the second clearance groove 13, the first guide hole 14 and the second guide hole 15 are maintained, allowing the first clamping member 33 and the second clamping member 34 to enter the clamping groove 11 along a preset straight path and insert into the corresponding slot 41. Simultaneously, the back support plate 18 enhances the overall torsional and bending resistance to prevent deformation caused by the clamping action, improving the stability and reliability of the cap removal action.

[0040] In some embodiments, the clamping mechanism 3 in the cap removal fixture provided by this utility model further includes a first limiting block 391 and a second limiting block 393. The first limiting block 391 has a first groove 392 and is connected to the first clamping seat 31. The first support plate 16 is at least partially embedded in the first groove 392. The second limiting block 393 has a second groove 394 and is connected to the second clamping seat 32. The second support plate 17 is at least partially embedded in the second groove 394. During the cap removal process, the first support plate 16 and the groove wall of the first groove 392 come into contact with each other to form a radial constraint, which restricts the degree of freedom of the first clamping seat 31 in the non-movement direction. At the same time, the second support plate 17 and the groove wall of the second groove 394 come into contact with each other to constrain the second clamping seat 32, which restricts the degree of freedom of the second clamping seat 32 in the non-movement direction. This can effectively suppress the lateral vibration or displacement generated by the first clamping seat 31 and the second clamping seat 32 during the clamping or resetting process, improve the stability of the movement of the first clamping member 33 and the second clamping member 34 along the preset straight trajectory of the first clearance groove 12 and the second clearance groove 13, and reduce cap removal failure or repeated operation caused by position deviation.

[0041] In some embodiments, a first blind hole 161 is provided on the first support plate 16, which matches the first elastic reset member 35. The first elastic reset member 35 is movably disposed in the first blind hole 161. A second blind hole 171 is provided on the second support plate 17, which matches the second elastic reset member 36. The second elastic reset member 36 is movably disposed in the second blind hole 171. The first blind hole 161 provides circumferential positioning and radial constraint to the end of the first elastic reset member 35, ensuring that the axis of the first elastic reset member 35 remains parallel to the direction of movement of the first clamping seat 31 during compression or rebound. At the same time, the second blind hole 171 provides circumferential positioning and radial constraint to the end of the second elastic reset member 36, ensuring that the axis of the second elastic reset member 36 remains parallel to the direction of movement of the second clamping seat 32 during compression or rebound. This enables the first clamping seat 31 and the second clamping seat 32 to be linearly reset, preventing deviation of the movement path of the first clamping seat 31 and the second clamping seat 32 due to bending or skewing of the reset member.

[0042] In some embodiments, the drive assembly 2 of the cap removal fixture provided by this utility model includes a mounting bracket 26. One end of the mounting bracket 26 is connected to a fixed base 1, and a rotating shaft 25 passes through the other end of the mounting bracket 26 and is rotatably connected to a second handle 24 and a first handle 23. The mounting bracket 26 can fix the rotating shaft 25 and the fixed base 1 as a whole, which helps to enhance the deformation resistance of the rotating shaft 25 under stress. Alternatively, one end of the mounting bracket 26 can be connected to the fixed base 1 by bolts, achieving a detachable connection between the fixed base 1 and the mounting bracket 26, facilitating maintenance of the fixed base 1. When the operator grips or releases the first gripping part 21 and the second gripping part 22, the first handle 23 and the second handle 24 will always rotate around a stable axis to transmit driving force to the first clamping seat 31 and the second clamping seat 32 respectively. This allows the first clamping member 33 and the second clamping member 34 to enter or exit the clamping groove 11 without deviation along the direction of the first clearance groove 12 and the second clearance groove 13, improving the reliability of the cap removal action.

[0043] In some embodiments, the first clamping member 33 includes a first support block 331 and a first clamping head 332. The first support block 331 is fixedly connected to the first clamping seat 31, and the first clamping head 332 is fixedly connected to the first support block 331. The projection of the first clamping head 332 toward the first support block 331 is located on the first support block 331. The second clamping member 34 includes a second support block 341 and a second clamping head 342. The second support block 341 is fixedly connected to the second clamping seat 32, and the second clamping head 342 is fixedly connected to the second support block 341. The projection of the second clamping head 342 toward the second support block 341 is located on the second support block 341.

[0044] The first support block 331 increases the contact area between the first clamping seat 31 and the first pressing head 332, dispersing the reaction force on the first pressing head 332 and preventing loosening or breakage of the connection. Furthermore, the smaller size of the first pressing head 332 allows it to accommodate smaller slots 41 and connectors 51. Similarly, the second support block 341 increases the contact area between the second clamping seat 32 and the second pressing head 342, dispersing the reaction force on the second pressing head 342 and preventing loosening or breakage of the connection. The smaller size of the second pressing head 342 also allows it to accommodate smaller slots 41 and connectors 51, ensuring that the first pressing head 332 and the second pressing head 342, after being inserted into their respective slots 41 on the feed tube 4, can withstand continuous loads and reliably press the connector 51 until it disengages from the slot 41.

[0045] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0046] The above embodiments only illustrate preferred implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
