[0063] The jig unlocking spinning mechanism of the embodiment of the present application is described in detail below with reference to the accompanying drawings.

[0064] Referring to Figures 1 to 6 As shown, the jig unlocking spinning mechanism provided by the embodiment of the present application comprises a base plate 10, a jig assembly 20, an upper unlocking assembly 30 and a rotating driving assembly 40.

[0065] Specifically, the jig assembly 20 is adapted to be transferred onto the base plate 10, and in a specific application, the jig assembly 20 can be mounted on a robot, and the robot can drive the jig assembly 20 to be transferred onto the base plate 10.

[0066] The jig assembly 20 comprises a carrier 201 and a pressing rod 202, the carrier 201 is provided with a workpiece position H20 and a plurality of locking hooks 2011 arranged around the workpiece position H20, the locking hooks 2011 are used to move inwardly of the workpiece position H20 to position and fix a workpiece after the workpiece is placed on the workpiece position H20. Exemplarily, the plurality of locking hooks 2011 are distributed on both sides of the workpiece position H20 respectively. The pressing rod 202 is horizontally arranged and pivotable about a vertical axis, and is used to press the workpiece on the workpiece position H20 tightly on the workpiece position H20 after the locking hooks 2011 are unlocked, so as to prevent the workpiece from being separated from the workpiece position H20.

[0067] The upper unlocking assembly 30 is arranged on the base plate 10, and is used to push the locking hooks 2011 to move and release the locking state of the workpiece on the workpiece position H20 after the jig assembly 20 is transferred onto the base plate 10. That is to say, after the workpiece on the jig is processed in the last process, the jig assembly 20 is transferred onto the base plate 10 by the robot, and then the locking hooks 2011 are pushed by the upper unlocking assembly to be unlocked by upwardly ejecting the upper unlocking assembly.

[0068] The rotating driving assembly 40 is arranged on the base plate 10 and is configured to drive the pressing rod 202 to rotate to above the workpiece position H20 and press the workpiece on the workpiece position H20 after the jig assembly 20 is transferred to the base plate 10. In the specific unlocking process, the pressing rod 202 can be driven to rotate a predetermined angle by the rotating driving assembly 40 after the upper unlocking assembly unlocks the lock hook 2011, so that the end of the pressing rod 202 rotates to above the workpiece position H20, and the workpiece on the workpiece position H20 is pressed by the pressing rod 202.

[0069] According to the jig unlocking and spinning mechanism provided by the embodiment of the present application, after the jig assembly 20 is transferred to the base plate 10, the lock hook 2011 can be moved to release the locking state of the workpiece on the workpiece position H20 by pushing the lock hook 2011 to move upward by the upper unlocking assembly 30, and then the pressing rod 202 in the jig assembly 20 is driven to rotate to above the workpiece position H20 and press the workpiece on the workpiece position H20 by the rotating driving assembly 40. In this way, after the jig is unlocked, the workpiece on the jig assembly 20 can be pressed by the pressing rod 202, and in the subsequent transfer process, the workpiece can be prevented from falling off, the effective and reliable connection between processes can be ensured, continuous and reliable automatic processing can be realized, and the processing efficiency can be improved.

[0070] Referring to Figures 3 to 5 In one embodiment of the present application, the pressing rod 202 is pivotable between the first position and the second position, and the bottom of the pressing rod 202 is provided with a sleeve 203 coaxial with the vertical axis, and the lower end of the sleeve 203 has a non-circular axial insertion hole and a radial gap H22 communicating with the axial insertion hole. Exemplarily, the pressing rod 202 can rotate within a range of 90 degrees to switch between the first position and the second position. The cross section of the axial insertion hole is quadrilateral.

[0071] The rotating driving assembly 40 includes a rotating shaft 401, a limiting block 402 and a first driver 403. The rotating shaft 401 is pivotably arranged on the base plate 10 and is matched with the axial insertion hole. The limiting block 402 has a protrusion 4021 adjacent to the rotating shaft 401, and the first driver 403 is connected with the rotating shaft 401 to drive the rotating shaft 401 to rotate.

[0072] When the jig assembly 20 is transferred to the base plate 10, the upper unlocking assembly 30 is adapted to be pushed upward to unlock the lock hook 2011, the pressing rod 202 is located at the first position and does not block the workpiece position H20, the rotating shaft 401 is inserted into the axial insertion hole, and the protrusion 4021 is out of position with the radial gap H22.

[0073] When the first driver 403 drives the rotating shaft 401 to rotate so that the pressing rod 202 rotates from the first position to the second position, the protrusion 4021 is aligned with the radial gap H22, and the pressing rod 202 is located above the workpiece position H20 and sinks to press on the workpiece of the workpiece position H20.

[0074] That is, the rotating shaft 401 on the rotating drive assembly 40 and the axial insertion hole at the lower end of the sleeve 203 on the pressing rod 202 can be axially relatively inserted, and after the insertion, the rotating shaft 401 and the sleeve 203 are relatively fixed in the circumferential direction, and when the rotating shaft 401 rotates, it can drive the sleeve 203 to rotate, and then drive the pressing rod 202 to rotate between the first position and the second position through the sleeve 203. The protrusion 4021 on the limiting block 402 corresponds to the radial gap H22 on the sleeve 203, and when the protrusion 4021 is misaligned with the radial gap H22, the pressing rod 202 is in the first height position, and when the protrusion 4021 is aligned with the radial gap H22, the pressing rod 202 can automatically fall to the second height position to press the workpiece on the workpiece position H20.

[0075] Specifically, the jig unlocking spinning process is as follows:

[0076] First, the mechanical hand transfers the jig assembly 20 to the bottom plate 10, and in this state, the pressing rod 202 is located at the first position and does not block the workpiece position H20, the rotating shaft 401 is inserted into the axial insertion hole, the protrusion 4021 is misaligned with the radial gap H22, and the pressing rod 202 is in the first height position. Then, the upper unlocking assembly is pushed up, that is, the upper unlocking assembly pushes the lock hook 2011 so that the lock hook 2011 is unlocked. Further, the first driver 403 drives the rotating shaft 401 to rotate, and since the rotating shaft 401 is fixed in the circumferential direction with the axial insertion hole, the rotating shaft 401 can drive the sleeve 203 and the pressing rod 202 to rotate, so that the pressing rod 202 rotates from the first position to the second position. When the pressing rod 202 rotates to the second position, at this time, the radial gap H22 on the sleeve 203 rotates to the upper and lower opposite position (i.e. "alignment") of the protrusion 4021, and the pressing rod 202 automatically sinks to the second height position under the action of gravity, and then presses on the workpiece of the workpiece position H20, and the protrusion 4021 is inserted into the radial gap H22 on the sleeve 203.

[0077] Therefore, in the embodiment, the cooperation of the rotating shaft 401 and the axial insertion hole, and the cooperation of the protrusion 4021 and the radial gap H22 are used to positively and simply structure to realize that after the pressing rod 202 rotates to the second position, it can automatically sink to press on the workpiece, ensure the pressing effect on the workpiece, the structure is simple, the realization principle is simple, and the action is reliable.

[0078] Reference Figures 1 to 2 and Figure 6As shown, in one embodiment of the present application, the carrier 201 is provided with a receiving groove H21 which is adapted to the pressing rod 202, and the workpiece site H20 is adjacent to the receiving groove H21. The bottom of the receiving groove H21 is provided with a sliding hole, the sleeve 203 is slidably arranged in the sliding hole and is pivotable, so that the pressing rod 202 can be floated up and down. When the pressing rod 202 is in the first position, the length direction of the pressing rod 202 is consistent with the length direction of the receiving groove H21 and is accommodated in the receiving groove H21.

[0079] Before the jig assembly 20 is transferred onto the base plate 10, the pressing rod 202 is located in the receiving groove H21 under the action of gravity, so that the pressing rod 202 does not excessively protrude from the carrier 201. When the jig assembly 20 is transferred onto the base plate 10 by the mechanical hand, the shaft 401 is inserted into the axial insertion hole. Since the protrusion 4021 is misaligned with the radial notch H22, the protrusion 4021 can lift the sleeve 203, so that the pressing rod 202 is lifted above the receiving groove H21. Then, the shaft 401 is driven to rotate by the first driver 403, so that the pressing rod 202 is driven to rotate to the second position. By misaligning the protrusion 4021 and the radial notch H22, the pressing rod 202 can be automatically lifted from the receiving groove H21 after the jig assembly 20 is combined with the base plate 10. Then, the pressing rod 202 is conveniently rotated from the first position to the second position and is automatically sunk and pressed on the workpiece. The structure is simple and the lifting and sinking actions are automatically completed. The rotation of the shaft 401 is matched, so that the one-time rotation and pressing are smoothly completed, and the structure and action are reliable.

[0080] Preferably, when the pressing rod 202 is rotated to the second position, the pressing rod 202 is perpendicular to the receiving groove H21, and the end of the pressing rod 202 extends above the workpiece site H20. That is, the pressing rod 202 can be rotated by 90 degrees, so that the pressing rod 202 is just perpendicular to the workpiece site H20 in the second position, and the reliability of the pressing rod 202 to the workpiece in the workpiece site H20 is ensured.

[0081] Referring to Figure 2 and Figures 4 to 5 As shown, in some embodiments of the present application, the sleeve 203 is provided with a spring 204, the upper end of the spring 204 abuts against the carrier 201, and the lower end of the spring 204 is fixedly connected to the lower end of the sleeve 203. When the sleeve 203 is slid upward, the spring 204 is compressed.

[0082] In this embodiment, the spring 204 exerts an elastic force downward on the sleeve 203, so that, on the one hand, the pressing rod 202 can be kept in the accommodating groove H21 before the jig assembly 20 is transferred; on the other hand, when the first driver 403 drives the pressing rod 202 to rotate from the first position to the second position after the jig assembly 20 is transferred to the base plate 10, the protrusion 4021 is aligned with the radial gap H22, and the pressing rod 202 can be quickly pressed downward under the elastic force, thereby ensuring the reliability and stability of automatic pressing of the pressing rod 202.

[0083] With reference to Figures 1 to 2 and Figure 6 In one embodiment of the present application, the upper unlocking assembly 30 includes an unlocking top plate 301, an unlocking head 302, and a second driver 303. The unlocking top plate 301 is installed on the base plate 10 through a guide assembly and is vertically slidable.

[0084] The unlocking head 302 is arranged on the unlocking top plate 301 and corresponds to the lock hook 2011. The unlocking head 302 cooperates with the lock hook 2011 to push the lock hook 2011 to actuate unlocking. The number of the unlocking heads 302 is the same as that of the lock hooks 2011, and each unlocking head 302 can unlock one lock hook 2011.

[0085] The second driver 303 is arranged on the base plate 10 and connected with the unlocking top plate 301 to drive the unlocking top plate 301 to slide vertically and force the unlocking head 302 to unlock the lock hook 2011 on the jig.

[0086] That is, the second driver 303 can drive the unlocking top plate 301 to move up and down, and the unlocking head 302 is installed on the unlocking top plate 301 and can move up and down with the unlocking top plate 301. When the unlocking head 302 moves upward, the unlocking head 302 generates a pushing force on the lock hook 2011 on the jig 201 to move the lock hook 2011 outward of the workpiece position H20 to release the pressing of the workpiece. Thus, it is ensured that each unlocking head 302 can synchronously unlock each lock hook 2011, which is efficient and reliable.

[0087] Advantageously, the unlocking head 302 has a guide slope to exert a pushing force on the lower end of the lock hook 2011 when the unlocking head 302 is pushed upward, so as to force the lock hook 2011 to move outward of the workpiece position H20 to unlock. The pushing force generated by the guide slope on the lower end of the lock hook 2011 can generate a horizontal component and a vertical component, which is beneficial to the movement of the lock hook 2011 in an upward and inclined direction, thereby achieving better unlocking effect.

[0088] With reference to Figures 4 to 6As shown, in one embodiment of the present application, the limiting block 402 has a through hole, the rotating shaft 401 is arranged in the through hole and can be pivoted around its axis.

[0089] The protrusions 4021 are two, the two protrusions 4021 are arranged on the top surface of the limiting block 402 and are symmetrically arranged with respect to the vertical plane passing through the axis of the rotating shaft 401; the two notches correspond to the two protrusions 4021 one by one.

[0090] In the embodiment, through the cooperation of the two symmetrically arranged protrusions 4021 and the two notches, the support of the sleeve 203 is stable in the case of misalignment of the protrusions 4021 and the radial notch H22, thereby ensuring the stable pressure rod 202, the overall structure is more reliable, and the whole unlocking spinning action is more stable.

[0091] Preferably, the bottom plate 10 is provided with a positioning pin, and the carrier 201 is provided with a positioning hole matched with the positioning pin, so that the jig assembly 20 is positioned when transferred to the bottom plate 10. In this way, through the cooperation of the positioning pin and the positioning hole, the combination of the jig assembly 20 and the bottom plate 10 is more smooth and the position is more accurate.

[0092] Advantageously, the bottom plate 10 is provided with a negative pressure suction nozzle for adsorbing and fixing the carrier 201. In this way, through the adsorption of the carrier 201 by the negative pressure suction nozzle, the fixation of the carrier 201 is more reliable.
