[0014] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0015] Reference Figures 1 to 4 As shown, this utility model provides an automatic loading and unloading device for a knob. In one embodiment, it includes a hopper 1 and a loading and unloading transfer device 2 arranged on one side of the hopper 1. The loading and unloading transfer device 2 includes a first robotic arm 21, a transfer fixing base 22 connected to the first robotic arm 21, and a transfer module installed on the transfer fixing base 22. The transfer module includes a picking lifting cylinder 23 installed on one side of the transfer fixing base 22, a picking connecting plate 24 connected to the picking lifting cylinder 23, a gripper base plate 25 installed on one side of the picking connecting plate 24, and a picking clamping cylinder 26 installed on one side of the gripper base plate 25. The picking clamping cylinder 26 also drives two clamping sliders 27, and one side of the clamping sliders 27 is also connected to a picking gripper 28. One side of the gripper base plate 25 is also connected to a photoelectric mounting plate, and a photoelectric switch 251 is also installed on the photoelectric mounting plate.

[0016] In this embodiment, the first robotic arm 21 can be an existing robotic arm that can move, rotate, and lift freely. When picking up materials, the picking lifting cylinder 23 can drive the picking connecting plate 24 to move up and down, thereby driving the gripper base plate 25 and the picking clamping cylinder 26 to move to a suitable position. Then, the picking clamping cylinder 26 drives the two clamping sliders 27 to move relative to each other, thereby driving the picking gripper 28 to close, thereby clamping the knob on the material bin 1. Then, under the drive of the first robotic arm 21, the clamped knob is transferred to the assembly position. At the same time, a photoelectric switch 251 is also provided to detect whether there is a knob on the tray in the material bin 1. In addition, in order to improve work efficiency, the number of transfer modules is set to two sets.

[0017] Preferably, in this embodiment, the material-grabbing jaw 28 includes a jaw connecting post connected to the clamping slider 27, and a material-grabbing clamping block integrally connected to the bottom of the jaw connecting post; the material-grabbing clamping block has a semi-cylindrical structure, and the flat sides of the two material-grabbing clamping blocks are arranged opposite each other. The semi-cylindrical structure of the material-grabbing clamping blocks and the flat sides of the two material-grabbing clamping blocks facing each other enable the jaws to make closer contact with the knob, ensuring the firmness of the knob clamping. Meanwhile, a first slide rail is arranged on the lower side of the gripper base plate 25 along the horizontal direction, and the clamping slider 27 is slidably connected to the first slide rail, which can ensure the stability of the sliding of the clamping slider 27.

[0018] Furthermore, a second slide rail is arranged vertically on one side of the material-picking connecting plate 24, and the gripper base plate 25 is slidably connected to the second slide rail; a limiting block 241 is also connected to the upper and lower parts of one side of the material-picking connecting plate 24, and the second slide rail is arranged between the two limiting blocks 241; a first equal-height screw is also installed on the limiting block 241 located on the upper part of one side of the material-picking connecting plate 24, and the lower part of the first equal-height screw moves through the limiting block 241 and connects to the top of the gripper base plate 25; a first buffer spring 242 is also sleeved on the first equal-height screw, and the first buffer spring 242 is located between the bottom of the limiting block 241 and the top of the gripper base plate 25. When the gripper descends to hold the knob, the first buffer spring 242 can play a buffering role.

[0019] In one embodiment, the hopper 1 includes two parallel pallet feeding mechanisms 11, and each pallet feeding mechanism 11 has a pallet lifting mechanism 12 arranged at one end; a pallet transfer mechanism 13 is also arranged above the two pallet feeding mechanisms 11.

[0020] One pallet feeding mechanism 11 is used for loading pallets, and the other pallet feeding mechanism 11 is used for unloading pallets; during operation, the worker stacks the pallets on... Figure 1 On the pallet feeding mechanism 11 on the left side, the pallet lifting mechanism 12, located at one end of the pallet feeding mechanism 11, lifts the pallet to a predetermined position. Then, the loading and unloading transfer device 2 removes the knobs one by one from the top pallet and assembles them at the assembly position. After the knobs are assembled, the loading and unloading transfer device 2 transfers the assembled knobs to the pallet feeding mechanism 11 on the right side for unloading. If all the knobs in the top pallet on the left pallet feeding mechanism 11 have been removed, the pallet transfer mechanism 13 will transfer the empty pallet to the pallet feeding mechanism 11 on the right side to wait for the assembled knobs to be loaded. In addition, a buffer position is arranged on one side of the right pallet feeding mechanism 11. The pallet transfer mechanism 13 can transfer the empty pallet to the buffer position for buffering, and then transfer it to the right pallet feeding mechanism 11 when needed.

[0021] Preferably, in this embodiment, the pallet feeding mechanism 11 includes a feeding translation cylinder 111 and a feeding translation seat 112 connected to the feeding translation cylinder 111; a feeding connecting plate 113 is connected to each side of the feeding translation seat 112, and a feeding sliding plate 114 is slidably connected to one side of each feeding connecting plate 113; a pallet bottom plate 115 is also connected between the tops of the two feeding sliding plates 114, and a clearance through hole is opened on the top of the pallet bottom plate 115 extending to one end; a pallet support rod 116 is integrally connected to the middle of the inner wall of one end of the clearance through hole; a handle 117 is also installed on one top end of the pallet bottom plate 115. Manually, the pallet bottom plate 115 can be pulled out using the handle 117, and then the pallet can be placed on the pallet bottom plate 115 and pushed back to its original position. The feeding translation cylinder 111 can drive the feeding translation seat 112 to move, thereby moving the pallet bottom plate 115 to a predetermined position, so that the pallet lifting mechanism 12 can lift the pallet.

[0022] Meanwhile, the pallet lifting mechanism 12 includes a pallet lifting module 121 and a lifting slide 122 connected to the pallet lifting module 121. Several pallet brackets 123 are spaced apart along one side of the lifting slide 122, and each pallet bracket 123 has a pallet support bar 124 connected to its top. A pallet limiting block 125 is connected to the top end of each pallet support bar 124, and a limiting extension extends upward from the top end of the pallet limiting block 125. The pallet lifting module 121 can be a linear module, which can drive the lifting slide 122 to move the pallet brackets 123 up and down, thereby lifting the pallet via the pallet support bar 124. Some pallet support bars 124 are also equipped with pallet limiting blocks 125, which can limit the position of the pallet and prevent the pallet from shifting or shaking during lifting.

[0023] Furthermore, the pallet transfer mechanism 13 includes a pallet translation module 131, a pallet translation frame 132 connected to the pallet translation module 131, a transfer lifting cylinder 133 installed at one end of the pallet translation frame 132, and a transfer suction plate 134 connected to the transfer lifting cylinder 133; each end of the bottom of the transfer suction plate 134 is connected to a suction cup mounting strip 135, and a transfer suction cup 136 is also installed on the suction cup mounting strip 135. The pallet translation module 131 can be a linear module, which can drive the pallet translation frame 132 to move, thereby transferring the pallet picked up by the transfer suction cup 136 to a predetermined position.

[0024] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
