[0029] This embodiment provides a quick-change miniature electric gripper. The electric gripper has a compact structure and a higher degree of miniaturization. It can be used with the robot end effector for parallel gripping operations, making it more convenient to use. In addition, the electric gripper adopts a quick-change structure design, which can better adapt to the robot end effector and facilitate the rapid replacement of the electric gripper, thereby improving the efficiency of use.

[0030] Combination Figures 1 to 5 As shown, the electric gripper in this embodiment includes a base 10, a drive unit 20, a gripper slide 30, and a quick-change connector 40. The drive unit 20 is located inside the base 10 and drives the gripper slide 30 to achieve parallel gripping operation. The quick-change connector 40 can cooperate with an external robot for use.

[0031] In this embodiment, the base 10 has an opening on one side, and the drive unit 20 is located inside the base 10. The drive unit 20 includes a transmission screw 21 and a moving seat 22. There are two moving seats 22, which are mounted on the transmission screw 21. When the transmission screw 21 rotates, the two moving seats 22 move towards each other or in opposite directions. There are two gripper slides 30, which are connected to the two moving seats 22 respectively. In this embodiment, the drive unit 20 is installed inside the base 10 and is driven by a drive motor (not shown in the figure). The moving seats 22 are threadedly engaged with the transmission screw 21. When the transmission screw 21 rotates, it causes the two moving seats 22 to move towards each other or in opposite directions. The gripper slides 30 are connected to the moving seats 22, so the moving seats 22 will drive the gripper slides 30 to move, thereby realizing the gripping operation.

[0032] Furthermore, in this embodiment, both ends of the base 10 are provided with side covers 50, and the side covers 50 are provided with a plurality of cable outlet holes 51. Both ends of the base 10 are embedded with end plates 60, and the end plates 60 are provided with mounting holes 61. Bearings 70 are provided in the mounting holes 61 to install the transmission screw 21. In this embodiment, the bearing 70 is a deep groove ball bearing 70, which can be effectively adapted to the end of the transmission screw 21 so that the transmission screw 21 can rotate more efficiently.

[0033] Combination Figures 3 to 5 As shown, a sealing plate 80 is provided between the two end plates 60 in this embodiment to block the opening of the base 10. The sealing plate 80 is provided with a slot 81. The gripper slide 30 is connected to the motion seat 22 through a connecting block. The connecting block is located in the slot 81. The sealing plate 80 can block the opening of the base 10, and the presence of the slot 81 does not affect the effective operation of the gripper slide 30.

[0034] In this embodiment, a guide rod 90 is provided between the two end plates 60. There are two guide rods 90 arranged in parallel. The gripper slide 30 is mounted on the guide rod 90 and moves along the length of the guide rod 90. In this embodiment, the guide rod 90 can guide the movement of the gripper slide 30 and improve its movement stability.

[0035] Combination Figure 1 and Figure 2As shown, the quick-connect connector 40 in this embodiment includes a first mounting block 41, a second mounting block 42, and a side locking block 43. The first mounting block 41 is mounted on the back of the base 10, and the side locking block 43 is located on the side of the first mounting block 41, locking the first mounting block 41 and the second mounting block 42 together. In this embodiment, the first mounting block 41, the second mounting block 42, and the side locking block 43 form the quick-connect connector 40. The second mounting block 42 has a quick-connect hole 421 at its center for connection with an external robot so that the electric gripper can be used. In this embodiment, the first mounting block 41 and the second mounting block 42 are locked together by the side locking block 43 and reinforced with screws so that they can be better adapted to the robot end effector for use.

[0036] In this embodiment, both the first mounting block 41 and the second mounting block 42 are circular mounting blocks. There are two side locking blocks 43, which are located on both sides of the first mounting block 41 respectively. The first mounting block 41 and the second mounting block 42 are locked together by screws to achieve effective fixation of the first mounting block 41 and the second mounting block 42.

[0037] Furthermore, the electric gripper in this embodiment also includes a cover 100, which is installed on one side of the base 10. The cover 100 is provided with a wire groove 101 to allow the gripper slide 30 to protrude from the cover 100, thereby facilitating the gripper slide 30 to perform gripping operations.

[0038] In actual use, the electric gripper of this embodiment is driven by the drive unit 20 to drive the gripper slide 30 to realize the use of the electric gripper. The quick-change connector 40 set on the back of the base 10 can be better adapted to the robot end effector for use, which facilitates the quick replacement of the electric gripper and improves the efficiency of use.
