[0041] The jig 2 is made of iron and the three plugs 27 are made of magnetic material;

[0042] When assembling keyboards of different specifications, the corresponding jig 2 needs to be replaced, first, the jig 2 to be replaced is placed in one of the storage frames 8 in sequence, it should be noted that the jig 2 is placed with the groove facing upwards, then the push plate 31 on the material taking plate 24 is inserted into the bottom frame 9 by controlling the upper electric telescopic cylinder 35 to start, at the same time, the release rod 30 is inserted into the L-shaped slot and the plug 27 is inserted into the corresponding insertion hole 28, then the release rod 30 is moved by controlling the lower stretchers 26 to start, at this time, the release rod 30 is inserted into the release slot 21, and the release rod 30 top end is pressed against the inclined surface of the release slot 21, because the positioning rod 19 can only slide up and down in the L-shaped slot, under the action of the release rod 30 pressing the inclined surface of the release slot 21, the positioning rod 19 is pressed to slide upwards;

[0043] At the same time, the compression return spring 20 is compressed, so that the positioning rod 19 is pulled out of the clamping slot 18, thereby releasing the sliding restriction of the L-shaped rod 12, then the lower frame 29 is moved by controlling the upper stretchers 25 to start, at the same time, the release rod 30 and the push plate 31 are moved, thereby pushing the L-shaped rod 12 to slide in the bottom frame 9 and gradually releasing the stretching of the upper spring 13, at the same time, the triangular block 17 is gradually reset, thereby releasing the pressing of the positioning block 14 on the pressing groove 15, under the elastic force of the lower spring 16, the positioning block 14 is pulled to slide to the middle, so that the positioning block 14 is pulled out of the lower through slot in the U-shaped frame 4, thereby releasing the position restriction of the L-shaped frame 10, and releasing the locking restriction of the jig 2;

[0044] Then the stacking mechanism can be controlled to drive the jig 2 to move to both sides, and the L-shaped frame 10 is pushed out of the U-shaped frame 4. Then the longitudinal guide rail 6 is controlled to drive the cross plate 11, the material taking plate 24 and the jig 2 to move upwards, so that the two jigs 2 are stacked together through the stacking mechanism. Then the longitudinal guide rail 6 is controlled to drive the jig 2 to move upwards, so that the stacked jigs 2 are moved into the empty storage frame 8. In this process, the top end of the jig 2 will press the inclined surface at the bottom of the limiting strip 22, thereby pushing the limiting strip 22 to slide into the sliding groove and compressing the limiting spring 23. Then when the jig 2 moves away from the limiting strip 22, the pressing on the limiting strip 22 is released, and the limiting strip 22 is pushed to reset under the elastic force of the limiting spring 23, so that the limiting strip 22 is clamped at the bottom end of the jig 2, limiting the position of the jig 2 in the storage frame 8. Then the upper electric telescopic cylinder 35 is controlled to drive the plug 27 to pull out of the socket 28 (it should be noted that the front side of the storage frame 8 is provided with a front groove for sliding of the material taking plate 24, which will not hinder the upward and downward sliding of the material taking plate 24, and can limit the position of the jig 2 in the storage frame 8);

[0045] Then the horizontal guide rail 7 is controlled to drive the storage frame 8 to move horizontally, and the storage frame 8 which needs to be replaced with the jig 2 is moved to the side of the material taking plate 24. In this process, the longitudinal guide rail 6 is controlled to drive the material taking plate 24 to move upwards, so that the material taking plate 24 is moved to the position beside the two jigs 2 at the uppermost position of the storage frame 8. Then the upper electric telescopic cylinder 35 is controlled to drive the material taking plate 24 to move to the rear side, so that the plug 27 is inserted into the socket 28 on the two jigs 2 at the uppermost position (at this time, the lower telescopic cylinder 26 is controlled to reset, which only drives the push plate 31 to move to the side of the L-shaped rod 12 and drives the release rod 30 to be inserted into the L-shaped slot). Then the longitudinal guide rail 6 is controlled to move upwards, so that the jig 2 is moved out of the storage frame 8. Then the upper electric telescopic cylinder 35 is controlled to drive the jig 2 to move forward. Then the longitudinal guide rail 6 is controlled to drive the jig 2 to move downwards. When the jig 2 moves to the front side of the U-shaped frame 4, the stacking mechanism is controlled to reset, and the upper electric telescopic cylinder 35 is controlled to drive the jig 2 to move rearward, so that the L-shaped frame 10 is inserted into the corresponding U-shaped frame 4;

[0046] Subsequently control the upper telescopic device 25 to start driving the lower frame 29 and the push plate 31 to move, and then push the L-shaped rod 12 to move and the triangular block 17 to move, and stretch the upper spring 13, and then through the movement of the triangular block 17, the inclined surface of the triangular block 17 will push the inclined surface of the extrusion groove 15, because the positioning block 14 can only slide up and down, so as to extrude the positioning block 14 to slide to both sides, and stretch the lower spring 16, so that the positioning block 14 is inserted into the lower through groove on the U-shaped frame 4, and the positioning rod 19 on the L-shaped rod 12 is moved to the position above the clamping groove 18, thereby releasing the extrusion of the positioning rod 19, and then the reset spring 20 is pushed down to insert the positioning rod 19 into the clamping groove 18, thereby limiting the reset of the L-shaped rod 12, and then the equipment can be controlled to reset, the installation of the jig 2 is completed, and then the transmission mechanism 3 is controlled to start replacing the jig 2 at the position beside the replacement mechanism, and the above operation can be repeated for replacement. Thus, the above operation is repeated until all jigs 2 are completely replaced.

[0047] As described above, through the design of the above structure, the jig 2 can be automatically removed from the transmission mechanism 3 of the assembly line 1, and then sent into the storage frame 8 for storage. Moreover, the jig 2 stored in the storage frame 8 can be automatically taken out and installed on the transmission mechanism 3, without the need for workers to use tools for replacement, thereby greatly improving the working efficiency of the device.

[0048] Based on the above embodiment, it is found that the above structure can only remove one jig 2 for replacement at a time, which is low in efficiency. In order to solve the above problem, the above structure is further improved.

[0049] The stacking mechanism comprises a bidirectional electric telescopic cylinder 32 fixedly connected to the middle part of the rear side of the horizontal plate 11. A pair of openings are provided through the outer wall of the horizontal plate 11. A moving frame 33 is horizontally and slidingly connected to the outer wall of the horizontal plate 11 on both sides. The output ends of the bidirectional electric telescopic cylinder 32 are fixedly connected to the side walls of the moving frame 33. A moving slot is provided through the side wall of one of the moving frames 33. A moving plate 34 is longitudinally and slidingly connected to the inner side of the moving slot. An upper electric telescopic cylinder 35 is fixedly connected to the front side of the moving plate 34 and the other moving frame 33. The output ends of the upper electric telescopic cylinder 35 are fixedly connected to the side walls of the material taking plate 24 through the moving plate 34 and the moving frame 33. An inclined slot 36 is provided on the side wall of the horizontal plate 11 beside the moving plate 34. Straight slots 37 are provided at both ends of the inclined slot 36. A round rod 38 is fixedly connected to the front side of the moving plate 34 and inserted into the inner side of the inclined slot 36.

[0050] After the two jigs 2 are released from the limit, the control stack mechanism is operated, first control the two-way electric telescopic cylinder 32 to start pushing the moving frame 33 to move to both sides, at this time it will drive the round rod 38 to slide in the straight slot 37 above, at the same time drive the material taking plate 24 and the jig 2 to move to both sides, make the L-shaped frame 10 move out of the U-shaped frame 4, then control the longitudinal guide rail 6 to drive the horizontal plate 11 to move up, that is, control the two-way electric telescopic cylinder 32 to start resetting, pull the two moving frames 33 to move to the middle, in this process, because one of the moving frames 33 is provided with a moving slot, the moving plate 34 slides in the moving slot, and the round rod 38 is inserted in the inclined slot 36 and the straight slot 37, so in the resetting process, it will drive the round rod 38 to slide from the straight slot 37 above into the inclined slot 36, and then drive the inclined slot 36 to be extruded, which will drive the round rod 38 to gradually move downward, the channel drives the moving plate 34 to move downward in the moving slot, and drives one of the material taking plates 24 and the jig 2 to move downward, and the other material taking plate 24 and the jig 2 normally translate;

[0051] Then the round rod 38 moves to the straight slot 37 below, at this time the two jigs 2 are in a staggered arrangement state, and then are stacked together, then the two-way electric telescopic cylinder 32 completes resetting, the two jigs 2 are completely stacked together, that is, the longitudinal guide rail 6 is controlled to move up, the jig 2 is sent into the storage frame 8, so that the two jigs 2 are removed at the same time, and in the subsequent material taking process, the above operation is repeated in reverse, that is, the two removed jigs 2 are opened for installation.

[0052] The moving end of the transverse guide rail 7 is fixedly connected with a pair of insertion frames 39, and the rear side of the storage frame 8 is fixedly connected with an L-shaped insertion plate 40 for inserting into the insertion frame 39. Through the arrangement of the insertion frame 39 and the L-shaped insertion plate 40, the storage frame 8 can be inserted into the moving end of the transverse guide rail 7, which facilitates quick removal and replacement of the storage frame 8, and further improves the convenience of the device.

[0053] As described above, through the design of the above structure, the two jigs 2 can be removed at the same time, and the removed jigs 2 can be stacked together and sent into the storage frame 8, thereby greatly shortening the replacement time of the device and further improving the convenience of the device.
