[0007] The beneficial effects of this utility model are:

[0008] The combination of the crank arm rocker assembly and the electric actuator II replaces the traditional double-headed electric cylinder with a long stroke, effectively reducing the equipment's procurement cost. At the same time, due to the self-locking nature of the worm gear and worm wheel, there is no need to install an additional braking device, further reducing the overall cost of the device.

[0009] The design of the self-locking drive component ensures the stability and reliability of the crank arm rocker assembly during the drive process. In addition, the setting of two limit switches effectively prevents structural interference that may occur during the movement of the gripper, thereby improving the safety of operation.

[0010] To drive the rocker arm assembly, while the worm gear and worm wheel have self-locking properties:

[0011] As a further improvement to the above technical solution: the self-locking drive assembly includes a motor, the top of the bracket is fixedly equipped with the motor, the worm gear connected to the sub-shaft of the motor meshes with the worm wheel, the worm wheel drives the crank arm rocker assembly through a central shaft connected to one end, and the central shaft passes through the bracket and is rotatably connected to it.

[0012] The beneficial effects of this improvement are: the controller drives the motor, which in turn causes the worm gear to rotate, thereby driving the rocker arm assembly, while the worm and worm wheel have self-locking properties.

[0013] To achieve centered gripping by the grippers:

The piston rods of the electric actuator are connected to the limiting plate, and the two sets of limiting plates are slidably arranged on the inner side of the protective seat.

[0021] The beneficial effect of this improvement is that by driving the electric push rod through the controller, two sets of oppositely arranged limit plates can clamp and limit the stacked stamped parts, thus maintaining the stability of the stacked stamped parts.

[0022] To limit the placement of stamped parts:

[0023] As a further improvement to the above technical solution: a placement seat is fixedly provided on one side of the base, and a stacking groove and a feeding groove are respectively opened at the center of the top surface of the base and the placement seat.

[0024] The beneficial effect of this improvement is that it limits the placement position of the stamped parts.

[0025] To avoid structural interference in the articulated rocker arm assembly:

[0026] As a further improvement to the above technical solution: a controller is fixedly provided on one side of the limiting plate, and the controller includes a PLC, a relay and a control switch. The PLC is electrically connected to the limit switch and the relay, and the relay is electrically connected to the motor.

[0027] The beneficial effects of this improvement are as follows: the contact signal of the limit switch serves as the input signal of the PLC. When either contact of the two limit switches is closed, the stop logic is triggered, the power supply to the motor is cut off, and structural interference of the crank arm rocker assembly is avoided. After the motor stops and the stamping parts are stacked, the PLC controls the motor to run again and switches to the opposite running state according to the previous running state (forward or reverse).

[0035] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.

[0036] like Figure 1-5As shown, a stamping parts stacking device includes a base 1. The top surface of the base 1 is connected to the lower side of a protective seat 2, and the upper side of the protective seat 2 is connected to the bottom surface of a 3. A moving component 7 is disposed below the 3. The moving component 7 is drivenly connected to a connecting seat 9. A feeding component 6 is installed on the connecting seat 9. The feeding component 6 includes an electric push rod 62. The cylinder of the electric push rod 62 is mounted on the connecting seat 9, and the piston rod of the electric push rod 62 is connected to a bracket 61. A self-... The lock drive assembly 68 and the self-locking drive assembly 68 drive and connect to the crank arm rocker assembly 63. The crank arm rocker assembly 63 is rotatably mounted on the bracket 61 and is connected to the sliding sleeve 65. The sliding sleeve 65 is slidably mounted on both ends of the guide rod 64. The guide rod 64 is fixed on the inner side of the bracket 61. The electric cylinder fixed on the bottom surface of the bracket 61 is connected to the electric control adsorber 66. The bottom surface of the sliding sleeve 65 is connected to the gripper 67 through the fixing rod. Two limit switches 60 are installed opposite each other on the guide rod 64 on both sides of the sliding sleeve 65.

[0037] The self-locking drive assembly 68 includes a motor 681, which is fixedly mounted on the top of the bracket 61. The worm gear 682 connected to the sub-shaft of the motor 681 meshes with a worm wheel 683. The worm wheel 683 drives the crank arm rocker assembly 63 through a central shaft connected to one end. The central shaft passes through the bracket 61 and is rotatably connected to it. The controller 8 drives the motor 681, causing the worm gear 682 to drive the worm wheel 683 to rotate, thereby driving the crank arm rocker assembly 63. At the same time, the worm gear 682 and the worm wheel 683 have self-locking properties.

[0038] The crank arm rocker assembly 63 includes a rotating plate 631, which is fixed on the central shaft of the worm gear 683. Two pins are mounted opposite each other on the bottom surface of the rotating plate 631, and each of the two pins is rotatably connected to one end of a rocker arm 632. The other end of the rocker arm 632 is rotatably connected to the top surface of the sliding sleeve 65 through the pins. The worm gear 683 drives the drive 791 to rotate. The two sets of rocker arms 632 rotatably connected to the bottom surface of the rotating plate 631 cause the two sets of sliding sleeves 65 slidably mounted on the guide rod 64 to slide relative to each other, thereby enabling the gripper 67 to achieve centering and clamping.

[0039] The moving component 7 includes a bearing housing 701, on which a lead screw 702 is rotatably mounted and a guide rod 703 is fixedly mounted. The lead screw 702 is connected to a servo motor 704, which is mounted on a bracket 61. The lead screw 702 is threadedly connected to a connecting seat 9, and the guide rod 703 is slidably inserted into the connecting seat 9. The user drives the servo motor 704 to rotate the lead screw 702 through the controller 8. The connecting seat 9, which is threadedly connected to the lead screw 702, can then slide on the outside of the lead screw 702 and the guide rod 703. The sliding connecting seat 9 drives the movement of the feeding component 6.

[0040] An electric push rod is fitted and fixed to the inner wall of the protective seat 2, and the piston rods of the electric push rod are all set towards the inner side of the protective seat 2. The piston rods of the electric push rod are connected to the limiting plate 4, and the two sets of limiting plates 4 are slidably arranged on the inner side of the protective seat 2. By driving the electric push rod through the controller 8, the two sets of oppositely arranged limiting plates 4 can clamp and limit the stacked stamping parts, and maintain the stability of the stacked stamping parts.

[0041] A placement seat 5 is fixedly provided on one side of the base 1, and a stacking groove and a feeding groove are respectively opened at the center of the top surface of the base 1 and the placement seat 5.

[0042] A controller 8 is fixedly mounted on one side of the limiting plate 4. The controller 8 includes a PLC, a relay, and a control switch. The PLC is electrically connected to the limit switch 60 and the relay, and the relay is electrically connected to the motor 681. The contact signal of the limit switch 60 serves as the input signal of the PLC. When either contact of the two limit switches is closed, the stop logic is triggered, the power supply to the motor 681 is cut off, and structural interference is avoided in the crank arm rocker assembly 63. After the motor stops and the stamped parts are stacked, the PLC controls the motor 681 to run again and switches to the opposite running state according to the previous running state, either forward or reverse.

[0043] The working principle and usage process of this utility model are as follows: When using this device, the user first places the stamped part in the feeding slot, and then drives the servo motor 704. At this time, the lead screw 702 rotates, and the connecting seat 9 slides on the outside of the lead screw 702, driving the feeding assembly 6 to move upward to the top of the feeding slot. After the feeding assembly 6 moves to the designated position, the self-locking drive assembly 68 is driven, causing the motor 681 to rotate. The worm gear 682 drives the worm wheel 683, and the rotating worm wheel 683 causes the rotating plate 631 to rotate. At this time, the rocker arm 632 drives the two sets of sliding... The sleeve 65 slides relatively away from the outside of the guide rod 64. When the sleeve 65 touches the limit switch 60, the motor 681 stops operating. At this time, the two sets of grippers 67 are extended to the maximum, driving the electric push rod 62 to move the two sets of grippers 67 to both sides of the stamping part. Then, the self-locking assembly 68 is driven in reverse to make the grippers 37 clamp the stamping part. Then, the servo motor 704 is driven in reverse to move the feeding assembly 6 and the stamping part to the upper side of the stacking trough. The stamping part is placed in the stacking trough by driving the self-locking drive assembly 68 and the crank arm rocker assembly 63.
