AI Technical Summary
Existing vacuum suction cups are easily damaged, inconvenient to change or adjust, have high assembly costs, and do not adhere firmly, leading to material damage and equipment downtime during handling.
An adsorption device was designed, including a rectangular cover plate, a sponge, a connecting flange, a connecting pipe, a three-way valve, and a pipe fitting. The sponge is made to fit tightly against the surface of the object by using a negative pressure pump, and the adsorption force is increased by using a partition to divide the space into a grid-like cavity.
It achieves a simple structure, low cost, and strong adsorption, protecting fragile items from damage and avoiding equipment downtime.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of material handling equipment technology, specifically a suction device. Background Technology
[0002] In industrial production and logistics handling, vacuum suction devices are widely used as efficient material handling tools for picking up and moving various objects. A common market practice is to combine suction cups and vacuum generators to pick up materials. However, silicone suction cups are easily damaged, inconvenient for changing product sizes, have high assembly costs, and are prone to poor adhesion, leading to problems such as missing particles and machine downtime. Utility Model Content
[0003] To address the problems mentioned in the background art, this utility model provides a suction device, including a cover plate with a recessed cavity at the lower end. A sponge is placed inside the cavity. A through hole is provided on the upper surface of the cover plate, and a connecting flange is provided along the outer edge of the through hole. One end of a connecting pipe is fixedly installed on the upper end of the cover plate through the connecting flange. A fixed flange is provided on the other end of the connecting pipe. A three-way valve is sleeved on the connecting pipe, and a connecting pipe joint is provided at the valve port of the three-way valve.
[0004] The cover plate is a rectangular plate structure.
[0005] The cover plate has mounting holes, and the fixing component is installed in the cavity through the mounting holes to set the partition.
[0006] The staggered arrangement of the partitions divides the cavity into multiple small rectangular grids.
[0007] The other end of the pipe fitting is connected to a negative pressure pump.
[0008] Compared with the prior art, this utility model has a simple structure, low cost, convenient use, and strong adsorption. Attached Figure Description

[0011] See Figures 1 to 2 1. Cover plate, 2. Sponge, 3. Cavity, 4. Connecting flange, 5. Connecting pipe, 6. Fixed flange, 7. Three-way valve, 8. Pipe fitting, 9. Partition. Detailed Implementation
[0012] The present invention will be further described below with reference to the accompanying drawings.
[0013] like Figure 1A suction device includes a cover plate 1, with a cavity 3 formed by the inward recess at the lower end of the cover plate 1. A sponge 2 is placed inside the cavity 3. A through hole is provided on the upper surface of the cover plate 1, and a connecting flange 4 is provided along the outer edge of the through hole. One end of a connecting pipe 5 is fixedly installed on the upper end of the cover plate 1 through the connecting flange 4. A fixing flange 6 is provided on the other end of the connecting pipe 5. A three-way valve 7 is sleeved on the connecting pipe 5, and a connecting pipe joint 8 is connected to the valve port of the three-way valve 7.
[0014] The cover plate 1 has a rectangular plate-like structure.
[0015] The cover plate 1 has a mounting hole 10. The fastener is installed in the cavity 3 through the mounting hole 10 to set the partition 9, so that the partition can be adjusted to the required position during use.
[0016] The staggered arrangement of partitions 9 divides the cavity into multiple small rectangular grids.
[0017] The cavity 3 is equipped with partitions 9, which are staggered to divide the cavity 3 into multiple small rectangular grids.
[0018] The other end of pipe connector 8 is connected to a negative pressure pump.
[0019] When an object needs to be adsorbed, the suction device is fixed to a robotic arm or other handling equipment. A negative pressure pump lowers the pressure inside chamber 3 to atmospheric pressure. Under atmospheric pressure, the sponge 2 adheres tightly to the object's surface. A partition 9 inside chamber 3 increases the contact area and suction force. Simultaneously, the sponge 2's cushioning properties protect fragile items from scratches or damage. After adsorption is complete, the robotic arm moves the suction device to pick up the object to the designated location. When releasing the object, the negative pressure pump stops, the pressure inside chamber 3 returns to atmospheric pressure, and the object detaches from the suction device under gravity.
