Description

Technical Field

[0001] This utility model relates to the field of glycerin suppository production technology, specifically a multi-functional material handling device. Background Technology

[0002] Glycerin suppositories are a common form of medicine packaging, usually made of soft polyethylene or polyester plastic bottles with a smooth surface, rounded shape, and a certain degree of elasticity. In modern pharmaceutical production and logistics packaging lines, large quantities of glycerin suppository products need to be grasped, transferred, and stacked quickly and neatly.

[0003] Currently, common gripping methods for small, lightweight, and smooth-surfaced items include manual gripping, traditional mechanical grippers, and simple vacuum suction cup devices. However, these methods have the following problems: manual gripping is inefficient, labor-intensive, and difficult to ensure production hygiene requirements, easily leading to product contamination; due to the soft and irregular shape of the enema bottle, traditional grippers are prone to product deformation, damage, or even slippage due to uneven gripping force. In addition, grippers can usually only grip one or a few products at a time, resulting in low efficiency; while simple vacuum suction cup devices avoid gripping damage to the product, the smooth curved surface makes the reliability of single suction cup adsorption insufficient, and the product is prone to falling off due to inertia during rapid movement. Utility Model Content

[0004] The purpose of this invention is to provide a multifunctional material gripping device that has the effects of stable and reliable gripping, precise and efficient release, and effective prevention of material displacement.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a multi-functional material gripping device, including a connecting plate and a positioning plate, wherein the connecting plate and the positioning plate are connected by bolts and form a sealed cavity between them; a lifting rod for connecting a robot arm is fixedly provided at the top of the connecting plate; a rotary joint is provided on the upper surface of the connecting plate; the rotary joint is connected to a vacuum connecting pipe for connecting an external vacuum pump; a vacuum controller communicating with the cavity is provided on the side of the connecting plate; multiple suction cup connecting pipes communicating with the inside of the cavity are fixedly provided at the bottom of the positioning plate; each suction cup connecting pipe has a suction cup at its end; and a material baffle is detachably connected to the bottom of the positioning plate through an installation structure.

[0006] A further feature of this invention is that the mounting structure includes a mounting base fixed to the bottom of the positioning plate, and the material baffle is connected to the mounting base by bolts.

[0007] A further feature of this invention is that the mounting base is an L-shaped plate, with its vertical side connected to the material baffle by bolts and its horizontal side connected to the positioning plate by bolts.

[0008] A further feature of this invention is that the vacuum controller is a solenoid valve or a vacuum breaking valve, and the vacuum controller is used to control the vacuum state of the cavity, thereby breaking the vacuum of the cavity to cause the material to fall off the suction cup.

[0009] A further feature of this invention is that the number of suction cup connecting tubes is multiple, and they are distributed in an array at the bottom of the positioning plate.

[0010] A further feature of this invention is that the rotary joint is a 360-degree rotary joint.

[0011] In summary, this utility model has the following beneficial effects: By uniformly distributing negative pressure within a sealed cavity formed by the connecting plate and the positioning plate, and employing a multi-suction tube and suction cup array for simultaneous adsorption, the adsorption area and adsorption force are increased. This effectively grips smooth, rounded enema bottles, overcoming the shortcomings of weak adsorption with a single suction cup, and ensuring that the material does not fall off during high-speed movement. The vacuum controller actively and quickly breaks the vacuum within the sealed cavity, injecting air into the suction cups, allowing the enema bottle to be released instantly and completely. This solves the problems of delayed detachment and inaccurate positioning caused by the stickiness of the material surface or residual negative pressure after simply cutting off the air source, greatly improving the accuracy of material release and production efficiency. A dedicated material baffle is provided, which laterally limits and physically blocks the adsorbed enema product during gripping and transportation, effectively preventing it from sliding or shifting due to inertia or external force, ensuring the stability of the handling process and the neatness of the stacking.

[0015] The present invention will be further described below with reference to the accompanying drawings of the embodiments thereof.

[0016] Please see Figures 1-2 In this embodiment of the utility model, a multi-functional material gripping device includes a connecting plate 1, a positioning plate 2, a lifting rod 4, and a material baffle 8.

[0017] The connecting plate 1 and the positioning plate 2 are connected by multiple hexagonal bolts. To ensure sealing, an annular sealing groove is machined on the contact surface of the connecting plate 1 and the positioning plate 2, and an O-ring (not shown in the figure) is embedded therein, so that a sealed cavity is formed between the two after they are connected.

[0018] A lifting rod 4 is welded and fixed at the top center of the connecting plate 1. The top of the lifting rod 4 is provided with a standard flange interface for quick and stable connection with the end of the actuator arm of the industrial robot.

[0019] On the upper surface of the connecting plate 1, a 360-degree rotary joint 301 is installed. The fixed end of the rotary joint 301 is fastened to a through hole on the connecting plate 1, and this through hole communicates with the sealed cavity. The rotating end of the rotary joint 301 is connected to a vacuum connecting pipe 3. The other end of the vacuum connecting pipe 3 is used to connect an external vacuum pump (not shown in the figure) to provide a vacuum source for the entire system.

[0020] On the side of the connecting plate 1, there is a two-position three-way solenoid valve (set by the PLC program) that serves as a vacuum controller 5. The air inlet of the solenoid valve is connected to the sealed cavity through an air pipe. Its default de-energized state is closed, maintaining the vacuum inside the cavity. When it is energized, it connects to the atmosphere, thereby filling the cavity with air and quickly breaking the vacuum.

[0021] At the bottom of the positioning plate 2, multiple suction cup connecting tubes 6 are vertically fixed. The suction cup connecting tubes 6 are distributed in a rectangular array. Each suction cup connecting tube 6 is connected to the sealed cavity above through the through hole on the positioning plate 2. Each suction cup connecting tube 6 is threaded to a rubber suction cup 7 for adsorbing materials.

[0022] At the bottom front side of the positioning plate 2, a material baffle 8 is connected via a mounting structure. Specifically, the mounting structure includes an L-shaped mounting base, the horizontal side of which is fastened to the side of the positioning plate 2 by two bolts. The material baffle 8 is a long strip of steel plate, which is connected to the vertical side of the mounting base by two bolts. To further enhance adaptability, a long hole is machined at the connection between the material baffle 8 and the mounting base. The front and rear position of the material baffle 8 relative to the positioning plate 2 can be adjusted by loosening the bolts. After adjustment, the bolts can be tightened again.

[0023] In use, the gripping device works in conjunction with the robot. Based on the length, width, and height of the material, the corresponding technical parameters are set. Before gripping the material, a material baffle 8 on the gripping device, under the robot's action (set by the PLC program), organizes the material to be gripped, ensuring it is in the same position. The gripping device then lowers itself so that the suction cups 7 on the gripping device make full contact with the material. The PLC program controls the external vacuum pump to start, continuously drawing a vacuum into the sealed cavity formed by the connecting plate 1 and the positioning plate 2 through the vacuum connecting pipe 3 and the rotary joint 301. The negative pressure is evenly transmitted through the cavity to all the suction cup connecting pipes 6 connected to the cavity, ultimately causing the suction cups 7 installed at the ends of the suction cup connecting pipes 6 to generate a strong suction force, thereby opening the plug. The material is firmly gripped; during the transfer process, the material baffle 8 plays a crucial role in limiting and blocking, effectively preventing the adsorbed material from sliding or shifting due to inertia during acceleration, deceleration, or turning, thus ensuring the stability of the handling process; when the material needs to be released, the PLC program sends a command to the vacuum controller 5, which (such as a solenoid valve) immediately acts, cutting off the vacuum path and instantly introducing external air into the sealed cavity, quickly destroying the vacuum in all suction cup connecting pipes 6 and suction cups 7, causing the negative pressure to disappear. As a result, the material is released smoothly, accurately, and completely to the designated position under its own gravity, completing the entire gripping, transfer, and release cycle or moving it to the required location.

[0024] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
