[0007] The baseplate provides support for the entire device. A mounting mechanism connects the baseplate to external connections. A drive source drives the baseplate in horizontal, parallel, and left-right motion. Pneumatic grippers are used to grasp tennis ball molds. Placing more than one pneumatic gripper at equal intervals allows for simultaneous grasping of multiple tennis ball molds, improving production efficiency. The folding rod design allows the baseplate to move laterally, driving adjacent pneumatic grippers, allowing for adjustment of the spacing between pneumatic grippers based on actual needs.

[0008] Preferably, the mounting mechanism is a mounting block, which is arranged in the middle of the upper end surface of the substrate and has a mounting hole preset on the mounting block.

[0009] The mounting holes are internal threaded bolt holes, which facilitate the connection of the mounting block with external connection devices.

[0010] Preferably, the driving source is a cylinder, which is arranged on one side of the upper end surface of the base plate, and the output end of the cylinder is connected to the base plate via a connecting block, and a limit block is provided at one end of the connecting block away from the cylinder.

[0011] The cylinder is an existing structure on the market in this field. It is connected to the external cylinder seat. When in use, the cylinder drives the base plate to move horizontally through the connecting block. When the connecting block moves, the design of the limit block plays a limiting role on it, so that the connecting block always keeps moving within this range.

[0012] Preferably, two sliding rods are arranged in parallel below the base plate, and more than one sliding block is arranged at equal intervals on each sliding rod, and the upper end surface of the sliding block is connected to the lower end surface of the base plate.

[0013] The base plate forms a sliding structure through the slider and the slide rod, which plays a role in limiting the movement of the base plate. This method is common knowledge in this field, so it will not be described in detail. The surface of the slider is connected to the bearing of the folding rod.

[0014] Preferably, a positioning block is provided on the upper end surface of the pneumatic gripper, and the pneumatic gripper forms a detachable connection structure with the slider through the positioning block.

[0015] The positioning block is pre-set with bolt holes and a detachable connection structure, which makes it easy for staff to disassemble and assemble the pneumatic gripper. It is not only convenient for staff to replace and maintain the pneumatic gripper in the future, but also convenient for installing a specified number of pneumatic grippers according to actual needs.

[0016] Preferably, it further comprises a gas distribution plate, which is arranged on the other side of the upper end surface of the substrate and is connected to the pneumatic gripper via a pipeline.

[0017] The air distribution plate adopts the existing structure in the market in this field, which is used to provide a power source to the pneumatic gripper so that the pneumatic gripper can be used normally.

[0018] The beneficial effects of the utility model are:

[0019] When the utility model is in use, the design of the folding rod enables the base plate to drive the adjacent pneumatic grippers to move when it moves horizontally, so that the distance between the pneumatic grippers can be adjusted according to actual needs. The pneumatic grippers adopt a detachable structure, which not only makes it convenient for the staff to replace and maintain the pneumatic grippers in the later stage, but also makes it convenient to install a specified number of pneumatic grippers according to actual needs, which is conducive to promotion and use.
