[0026] The product transmission device 2 includes a Y-axis translation mechanism 21 arranged below the screw removal mechanism 11, a Y-axis translation seat 22 connected to the Y-axis translation mechanism 21, a product mold seat 23 arranged on the top of the Y-axis translation seat 22, and a clamping mechanism installed on the Y-axis translation seat 22 and used to clamp and limit the product mold seat 23.

[0027] Continue to refer to Figures 1 to 4 As shown, in this embodiment, a workbench 4 is also included, and the work frame 12 is a gantry frame. The workbench 4 is located between the two columns of the gantry frame, and the product transmission device 2 is installed on the workbench 4; the workbench 4 uses an aluminum profile structure, which can reduce the cost of the equipment, and the X-axis translation mechanism 13, the Z-axis lifting mechanism 14 and the Y-axis translation mechanism 21 are all driven by a closed-loop stepping motor in conjunction with a synchronous belt, wherein the synchronous belt uses the specification of S3M, the synchronous wheel uses 25 teeth, and the lead is equivalent to 75MM; in order to recycle the screws, a vacuum suction nozzle 115 is provided on the screw removal mechanism 11, and after the screws are removed, they are immediately sucked up by vacuum, and then blown off at the designated position to realize automatic recycling; in addition, the product mold seat 23 adopts a sub-mother mold method, that is, the sub-mold is installed on the mother mold, and the sub-mold can be removed. By making more sub-molds, it can be used alternately with CNC; when removing products of different sizes, the vacuum suction nozzle 115, the batch head 114 and the corresponding sub-mold can be replaced, which is convenient to use.

[0028] During operation, the product mold seat 23 is first manually placed on the Y-axis translation seat 22, and the clamping mechanism clamps and fixes the product mold seat 23; then, the Y-axis translation mechanism 21 drives the product mold seat 23 to move to the bottom of the screw removal mechanism 11; then, the screw removal mechanism 11 descends, the screwdriver bit 114 is aligned with the screw, and the electric screwdriver 113 starts to rotate. At the same time, the Z-axis lifting mechanism 14 slowly rises to remove the screw; when removing the screw, the air source connector is connected to the external vacuum negative pressure air source, the screw is sucked through the vacuum connector, the Z-axis lifting mechanism 14 rises, the X-axis translation mechanism 13 drives the screw removal mechanism 11 to move to the throwing point, and the vacuum connector is connected to the positive pressure air source to blow down and release the screw for recycling, and then the above-mentioned screw removal action is repeated until all the screws on the product mold seat 23 are removed; then, the Y-axis translation mechanism 21 drives the product mold seat 23 to reset, the sub-mold is manually removed, and then another sub-mold is put in, and this reciprocating process is repeated.

[0029] In one embodiment, the screw-removing mechanism 11 also includes a first mounting seat 116; a guide shaft is installed at each of the two ends of the top of the first fixing seat 112, and a limit plate 117 is also fixedly installed on the upper part of the guide shaft; a linear bearing 118 is also installed at the lower part of each guide shaft, and the two ends of the first mounting seat 116 are respectively connected to a linear bearing 118; a first spring 119 is also sleeved on the guide shaft, and the two ends of the first spring 119 are respectively abutted against the bottom of the limit plate 117 and the top of the linear bearing 118; the electric screwdriver 113 is installed on the first mounting seat 116.

[0030] In order to solve the problem that the screw removal speed does not match the speed of the Z-axis lifting mechanism 14, in this embodiment, a first spring 119 and a linear bearing 118 are arranged in the screw removal mechanism 11, and the electric screwdriver 113 will rotate rapidly when removing the screw (when the screwdriver bit 114 rotates to remove the screw, the electric screwdriver 113 will rise relative to the guide shaft under the influence of the reaction force, thereby squeezing the first spring 119, and under the influence of the restoring force of the first spring 119, the screwdriver bit 114 will keep pressing the screw), and at the same time, the Z-axis lifting mechanism 14 is slowly lifted, but the screwdriver bit 114 must keep pressing the screw, which relies on the force of the first spring 119, and flexible removal can be achieved.

[0031] In one embodiment, a first slide rail is arranged along the vertical direction on one side of the Z-axis lifting seat 15, and a first through hole is also opened at the top of the first fixed seat 112 corresponding to the first slide rail; the first lifting slide plate 111 is L-shaped, and the L-shaped vertical end of the first lifting slide plate 111 is arranged through the first through hole and is slidably installed on the first slide rail; the L-shaped horizontal end of the first lifting slide plate 111 extends to the bottom of the first fixed seat 112, and the vacuum suction nozzle 115 is installed at the bottom of the L-shaped horizontal end of the first lifting slide plate 111; a stop block 16 is also extended outward from one side of the L-shaped vertical end of the first lifting slide plate 111, and the stop block 16 is located above the first fixed seat 112;

[0032] In this embodiment, a stop block 16 is extended outward from one side of the first lifting slide 111 to prevent the first lifting slide 111 from falling off the first slide rail. At the same time, the Z-axis lifting mechanism 14 includes a second fixed seat connected to the X-axis translation mechanism 13, and a Z-axis driving module installed in the second fixed seat; the Z-axis lifting seat 15 is connected to the Z-axis driving module; a first adjustment seat 101 is also installed on one side of the second fixed seat, and a first limiting slide groove is also opened on one side of the first adjustment seat 101 in the vertical direction; an adjustment slider is also arranged in the first limiting slide groove, and a stop rod 102 is also connected to one side of the adjustment slider in the horizontal direction; a first limiting rod 103 is also connected to the top of the first lifting slide 111, and one end of the first limiting rod 103 extends to the top of the stop rod 102.

[0033] When the Z-axis lifting mechanism 14 drives the Z-axis lifting seat 15 to descend to remove the screw, the first limiting rod 103 will hit the stop rod 102. Under the influence of the reaction force, the first lifting slide plate 111 will rise, thereby driving the vacuum suction nozzle 115 to rise, so that the lower part of the screwdriver bit 114 can pass through the suction nozzle, thereby facilitating the removal of the screw. When removing the screw, the Z-axis lifting mechanism 14 will drive the Z-axis lifting seat 15 to rise, and the stop rod 102 will cancel the blocking force on the first limiting rod 103, and then the first lifting slide plate 111 will descend, and the screwdriver bit 114 will return to the vacuum suction nozzle 115 so that the vacuum suction nozzle 115 can absorb the screw. According to actual use requirements and environment, the position of the adjusting slider can be adjusted and then locked and fixed with screws to meet the needs of screw removal at different heights.

[0034] In one embodiment, the Y-axis translation seat 22 includes a first bottom plate connected to the Y-axis translation mechanism 21, a support column connected to the top of the first bottom plate, and a first top plate installed on the support column; a limit block 24 is installed at each of the four corners of the top of the first top plate, and a limit groove with an arc-shaped structure is opened on one side of each limit block 24; the product mold seat 23 is arranged on the first top plate, and the four corners of the product mold seat 23 are arranged in a limit groove. The four corners of the product mold seat 23 can be limited by the limit grooves of the limit blocks 24 to prevent it from shaking randomly when the screws are removed. At the same time, the clamping mechanism includes a clamping cylinder 25 installed on the first bottom plate, and a clamping rod 26 connected to the clamping cylinder 25; one end of the clamping rod 26 extends toward the top of the product mold seat 23. There are two groups of clamping cylinders 25, which are arranged close to one end of the first top plate respectively, so that the two clamping rods 26 can clamp and limit the two ends of the top of the product mold seat 23 to ensure its stability.

[0035] In one embodiment, a material storage box 3 is further included, which is arranged on one side of the product transmission device 2. The removed screws can be placed in the material storage box 3 for recycling. At the same time, a scraper plate 31 is installed between the two sides of the top of the material storage box 3; a scraper groove 32 is also provided on one side of the scraper plate 31. In order to solve the problem that a small part of the screws and the bit 114 are stuck, a scraper groove 32 is provided on one side of the scraper plate 31. The inner diameter of the scraper groove 32 is smaller than the diameter of the screw and larger than the diameter of the bit 114. The bit 114 moves from one side of the scraper groove 32 to the scraper groove 32, and then rises. Since the inner diameter of the scraper groove 32 is smaller than the diameter of the screw, the screw will hit the bottom of the scraper plate 31, and then the screw and the bit 114 are separated and fall off in the material storage box 3.

[0036] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
