[0042] Please refer to the attached document. Figures 1-5 This application provides a gasket transfer device 100, which is applied to a developing line equipment and is used to transfer gaskets; the gaskets have magnetic force.

[0043] Please refer to the attached document. Figures 1-5In this embodiment, the gasket transfer device 100 includes a base 10, a vertical rod 20, a support rod 30, and a gasket transfer assembly 40. The base 10 is placed on the ground or a tabletop. The vertical rod 20 is connected to the base 10 and arranged vertically. The support rod 30 is arranged horizontally.

[0044] Please refer to the attached document. Figures 1-5 In this embodiment, the base 10 serves as a support component for the pad transfer device 100. The base 10 supports the vertical rod 20, the support rod 30, and the pad transfer assembly 40. The base 10 is placed on the ground or a tabletop to ensure that the pad transfer device 100 is stably placed on the ground or tabletop, thus preventing the pad transfer device 100 from easily shaking.

[0045] A vertical rod 20 is provided on the upper side of the base 10. The vertical rod 20 is connected to the base 10 and arranged in the vertical direction so that the vertical rod 20 can be fixed to the upper side of the base 10 in the vertical direction.

[0046] The support rod 30 is arranged in a horizontal direction; the support rod 30 is rotatably connected to the vertical rod 20 and rotates in the horizontal direction relative to the vertical rod 20; so as to adjust the horizontal position of the support rod 30 relative to the vertical rod 20.

[0047] The pad transfer assembly 40 includes a first movable seat 41 and an electromagnet 42. The first movable seat 41 is disposed on the lower side of the support rod 30 and is movably connected to the support rod 30. It moves along the length of the support rod 30 to adjust the length position of the first movable seat 41 relative to the support rod 30. The electromagnet 42 is connected to the first movable seat 41 and its position is adjusted as the first movable seat 41 moves to achieve the movement effect of the electromagnet 42. The electromagnet 42 attracts the pad when energized and detaches from the pad when de-energized. At this time, when the electromagnet 42 is energized, the electromagnet 42, driven by the first movable seat 41 and the support rod 30, transfers the pad to an external storage frame to achieve automated pad transfer. This avoids manual transfer of the pad, prevents hand injuries, and improves the transfer efficiency and safety of the pad transfer device 100.

[0048] Please refer to the attached document.

When electromagnet 42 is energized, the lower side wall of electromagnet 42 can contact the upper surface of the pad, so that electromagnet 42 can attract the upper surface of the pad. This facilitates the transfer of the pad attracted by electromagnet 42 as the first movable seat 41 moves relative to the first slide 31. When the pad attracted by electromagnet 42 is facing the external storage frame, electromagnet 42 detaches from the pad in the de-energized state, so that the pad can automatically fall from top to bottom into the external storage frame.

[0049] Please refer to the attached document. Figures 1-5 In this embodiment, a first linear motion module 50 is provided between the first movable seat 41 and the first slide section 31.

This allows the first movable seat 41 to move automatically relative to the support rod 30 under the action of the first linear motion module 50, which facilitates the automatic transfer of the pad attracted by the electromagnet 42. This avoids the pad being transferred manually, prevents hand injuries, and improves the transfer efficiency and safety of the pad transfer device 100.

[0050] Please refer to the attached document. Figures 1-5In this embodiment of the application, when the first linear motion module 50 is a first linear motor, the fixed end of the first linear motion module 50 serves as the first stator of the first linear motor; the moving end of the first linear motion module 50 serves as the first mover of the first linear motor; there is a magnetic force between the first mover and the first stator so that the opposite poles of the first mover and the first stator repel each other, thereby facilitating the movement of the first mover relative to the first stator.

[0051] Please refer to the attached document.

Optionally, the support rod 30 rotates 180° each time under the action of the rotating module 60. When the electromagnet 42 is de-energized, the pad is transferred to the external storage frame.

[0053] Please refer to the attached document. Figures 1-3 In this embodiment, a rotating hole 30a is provided at the middle position of the support rod 30; the vertical rod 20 passes through the rotating hole 30a; the fixed end of the rotating module 60 is connected to the vertical rod 20; the rotating end of the rotating module 60 supports the support rod 30 and drives the support rod 30 to rotate along the axis of the rotating hole 30a, so that the vertical rod 20 can achieve a rotation effect relative to the support rod 30 through the space of the rotating hole 30a, ensuring that the vertical rod 20 can rotate from 0° to 360° relative to the support rod 30. Optionally, the rotating module 60 is a disc-type rotary motor.

[0054] Please refer to the attached document. Figure 1In this embodiment, the gasket transfer device 100 further includes a second movable seat 70, which is located between the vertical rod 20 and the support rod 30 and supports the rotating module 60. The second movable seat 70 is movably connected to the vertical rod 20 and moves along the length direction of the vertical rod 20. This allows for adjustment of the length position of the second movable seat 70 relative to the vertical rod 20, thereby facilitating the adjustment of the lifting position of the rotating module 60 as the second movable seat 70 moves. Simultaneously, the support rod 30 and the gasket transfer assembly 40 are raised and lowered.

[0055] The vertical rod 20 is provided with a second slide section 21, which extends along the length direction of the vertical rod 20 and is located on the surface of the support rod 30.

A second linear motion module 80 is provided between the second movable seat 70 and the second slide section 21. The fixed end of the second linear motion module 80 is connected to the second slide section 21, and the movable end of the second linear motion module 80 is connected to the second movable seat 70, driving the second movable seat 70 to move relative to the support rod 30.

The plate inlet sensor is electrically connected to the pad transfer device 100 so that the plate inlet sensor can sense the position of the pad and the location of the pad, and then transmit the signal to the pad transfer device 100. The pad transfer device 100 calculates the time to remove the pad based on the time point of the pad entry sensed by the plate inlet sensor and the distance between the plate inlet sensor and the pad transfer device 100.

[0057] When the electromagnet 42 of the pad transfer device 100 is energized, it attracts the pad.
