Description

Technical Field

[0001] This utility model relates to the field of gripping device technology, specifically to a pneumatic gripping device for packing boxes. Background Technology

[0002] Currently, with the improvement of people's living standards, many products, such as liquor and bottled condiments, are packaged in gift boxes to meet people's high-quality demands. Case packing machines are devices that pack products into boxes. These automated machines replace workers in the traditional task of packaging products, greatly improving production efficiency.

[0003] A prior art patent with publication number CN207482311U discloses a solution including a feeding belt conveyor, a carton roller conveyor, a robot gripper, and a positioning and packing mechanism. The carton roller conveyor is located beside the feeding belt conveyor. The robot gripper is mounted above the feeding belt conveyor and the carton roller conveyor where they contact each other via a bracket. The positioning and packing mechanism is mounted on the carton roller conveyor and positioned directly below the robot gripper. The positioning and packing mechanism includes a frame, a drawer plate mounted on the frame, a drawer plate cylinder, and a material guide assembly. The drawer plate is positioned directly below the material guide assembly and is slidably mounted on the frame. The drawer plate is connected to the output shaft of the drawer plate cylinder, which is parallel to the carton roller conveyor. This improves the packing efficiency and quality of the product.

[0004] As existing devices are used, the shortcomings of this technology have gradually become apparent, mainly in the following aspects:

[0005] First, during the process of the existing robotic arm grabbing and transporting the entire set of boxes, the boxes are prone to falling off, affecting the stability of the transport process.

[0006] Secondly, existing robotic arms are limited by the placement of boxes, making it difficult to quickly grasp them and thus reducing packing efficiency.

[0007] As can be seen from the above, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0009] To achieve the above objectives, the present invention provides the following technical solution.

[0010] A pneumatic gripping device for packing includes a support base, on which a robotic arm body is horizontally slidably mounted along the longitudinal direction. The output end of the robotic arm body is connected to a mounting plate. Several pneumatic suction cups are evenly distributed on the front of the mounting plate. A tray is provided below the mounting plate, which is slidably arranged along the back of the pneumatic suction cups to the bottom.

[0011] As an optimized solution, several cylinders are horizontally and parallelly fixed to the back of the mounting plate, and the telescopic ends of the cylinders are connected to the support plate.

[0012] As an optimized solution, a connecting plate is vertically fixed to the back of the pallet, and the telescopic end of the cylinder is fixedly connected to the connecting plate.

[0013] As an optimized solution, several reinforcing ribs are also fixedly connected in parallel between the upper surface of the connecting plate and the support plate.

[0014] As an optimized solution, several of the pneumatic suction cups are evenly distributed in a matrix on the mounting plate.

[0015] As an optimized solution, a connecting frame is fixedly connected to the back of the mounting plate, and the output end of the robotic arm body is fixedly connected to the connecting frame.

[0016] As an optimized solution, a clearance gap is provided between the upper surface of the tray and the lower surface of the mounting plate.

[0017] As an optimized solution, two guide rails are fixedly connected in parallel on the support base, and guide slides that are slidably mounted on the guide rails are fixedly connected in parallel on the lower end of the robotic arm body.

[0018] As an optimized solution, the support base is rotatably mounted with a longitudinal lead screw in the area between two guide rails, and a drive seat that is threadedly connected to the longitudinal lead screw is fixed to the lower end of the robotic arm body.

[0019] As an optimized solution, two end seats are fixedly connected side by side on the support base, and the two ends of the longitudinal lead screw are rotatably mounted on the two end seats.

[0020] As an optimized solution, a servo motor for driving the longitudinal lead screw to rotate is fixed to one of the end seats.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] By having several pneumatic suction cups evenly distributed in a matrix on the mounting plate, the stability of clamping several boxes can be improved; by having a sliding support plate at the bottom of the mounting plate, the bottom of the box assembly can be supported by the support plate during the transportation of the clamped boxes, realizing bidirectional support for the box assembly, preventing the boxes from falling during transportation, and improving the stability during transportation.

[0023] The main body of the robotic arm is slidably mounted on the support base, which allows the main body of the robotic arm to be moved according to the placement position of the box assembly, facilitating the clamping and packing of the box assembly and improving convenience.
