[0002] The lid of the can (such as square lid, round lid, etc.) is used to seal the can body. During the assembly process of the lid and the can body, in order to seal the can body and prevent the lid from rusting, glue needs to be injected on its contour edge. In order to facilitate the opening of the lid, there will be a circle of engraved lines on the surface. In order to prevent the engraved lines from rusting, repainting will be done on the engraved lines.

[0003] On the production line of the pull-open lid, the pull-open lid is transported by a belt conveyor and then clamped by a base plate. When the pull-open lid is being injected with glue or repainted, the stay time of each pull-open lid is very short. After the pull-open lid reaches the designated position, it is necessary to quickly clamp and position the pull-open lid. After the pull-open lid is injected with glue or repainted, it is also necessary to quickly release it so that the pull-open lid can be transmitted out. Therefore, it is necessary to provide a quick positioning and clamping tooling for the pull-open lid, which can facilitate the positioning and stopping of the pull-open lid while meeting the transportation requirements.

[0020] Specifically, the linear guide rail 2 is located at the front and rear ends of the left seat plate 3 and the right seat plate 4, and the left seat plate 3 and the right seat plate 4 are both rectangular frame structures.

[0021] In this embodiment, the linear slide rail 2 is mainly used to support and guide the left seat plate 3 and the right seat plate 4 to perform reciprocating linear motion in a given direction.

When the easy-open cover reaches the specified position (a photoelectric switch can be installed on one side of the belt conveyor here. When the photoelectric switch detects that a product has passed, it sends a signal, and the production control system sends an operation instruction to the tooling), the stepper motor 8 drives the swing arm 5 to swing a certain angle, and under the action of the connecting rod, the left seat plate 3 and the right seat plate 4 are pulled inward or outward, so that they are clamped and fixed by the transverse clamping plate 9, and then driven by the cylinder 10 to drive the longitudinal clamping plate 11 to clamp and position, the easy-open cover can be injected with glue or re-coated. After completion, the longitudinal clamping plate 11 and the transverse clamping plate 9 are reset, and can be quickly released to allow the easy-open cover to be transmitted.
