Description

Technical Field

[0001] This utility model belongs to the technical field of belt conveyor devices, and in particular relates to an adsorption conveyor belt. Background Technology

[0002] Adsorption conveyor belts have wide applications in the photovoltaic, electronics, 3C digital, printing or packaging, logistics sorting and other industries for the production of thin sheet workpieces.

[0003] In the prior art, CN112919019A discloses an anti-sag adsorption conveyor belt, including a suction platform and a conveying device. The suction platform has an adsorption surface with workpiece suction grooves. The conveying device includes a belt that runs along the adsorption surface, avoiding the workpiece suction grooves. A belt suction groove is provided at the position where the adsorption surface contacts the belt. When this adsorption conveyor belt is installed upside down, the workpiece suction grooves generate adsorption force, adsorbing the workpiece tightly onto the belt. The belt suction grooves hold the belt in place, preventing sagging and ensuring that thin workpieces remain close to the workpiece suction grooves during transport. Sufficient negative pressure suction is achieved, preventing them from falling off the belt.

[0004] However, this type of adsorption conveyor belt has workpiece suction grooves and belt suction grooves set on the adsorption surface to adsorb the workpiece and belt respectively. This requires the supply of two compressed gas sources, which consumes a lot of compressed gas and thus has relatively high energy consumption. Utility Model Content

[0005] The technical problem to be solved by this invention is to provide an adsorption conveyor belt that can reduce the use of compressed gas and thus reduce energy consumption, so as to overcome the shortcomings of the existing technology.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] An adsorption conveyor belt includes an adsorption platform and a conveying device. The adsorption platform has a downward adsorption surface, and the conveying device includes a belt running along the adsorption surface. A closed air cavity is formed in the adsorption platform, and a jet flow channel is formed from the air cavity through the adsorption groove to the outside. The belt is characterized by having adsorption holes spaced apart along the running direction, and the adsorption surface has adsorption grooves spaced apart along the path of the adsorption holes.

[0008] By employing the above technical solution, adsorption holes are spaced apart along the running direction on the belt, and adsorption grooves are spaced apart along the path of the adsorption holes on the adsorption surface. During belt operation, the belt is not only adsorbed by the adsorption grooves, but the adsorption grooves also communicate with the adsorption holes as they pass through, thus adsorbing the workpiece. Therefore, this invention only requires one path of compressed gas to act on the adsorption grooves to achieve the function of adsorbing both the belt and the workpiece, eliminating the need for two paths of compressed gas, reducing the use of compressed gas and lowering energy consumption.

[0009] In a specific embodiment of this invention, the jet channel is divided into an inner channel located between the gas chamber and the adsorption tank, and an outer channel located between the adsorption tank and the outside. The aperture of the inner channel is smaller than that of the outer channel. This structure enables the jet channel to generate a high-speed flow, thereby causing the adsorption tank to generate negative pressure suction.

[0010] In a specific embodiment of this invention, the length of the adsorption hole is greater than the distance between adjacent adsorption grooves. This structure ensures that during belt operation, the adsorption grooves effectively hold the belt in place, while each adsorption hole remains connected to the adsorption groove, thus guaranteeing that the adsorption holes effectively adsorb the workpiece throughout the belt's movement.

[0011] In a specific embodiment of this invention, the width of the adsorption hole is greater than the width of the adsorption groove. This structure ensures that even if the belt deviates during operation, the adsorption hole will always remain in communication with the adsorption groove.

[0012] In a specific embodiment of this invention, the suction table has two parallel, spaced-apart adsorption surfaces, and the transmission device includes two synchronously running belts that run against the two adsorption surfaces respectively. Each adsorption surface of the suction table is matched with a corresponding suction cavity and a jet flow channel. This allows for the simultaneous adsorption and transmission of workpieces using two belts, improving both the adsorption and transmission effects.

[0013] In a specific embodiment of this utility model, multiple air chambers are spaced apart within the suction table along the belt's running direction. Each air chamber corresponds to and connects to multiple adsorption tanks and jet channels in a group. Each air chamber is equipped with a solenoid valve to control the entry of compressed gas. By controlling the on / off state of the solenoid valve in the corresponding air chamber, the adsorption tank corresponding to that air chamber can be controlled to generate suction, thereby controlling the adsorption and placement of workpieces at the required positions to meet workpiece picking needs. From the above detailed description, it can be seen that the adsorption conveyor belt of this utility model has the advantage of reducing the use of compressed gas and thus reducing energy consumption.

[0020] like Figures 1 to 4 As shown, the present invention provides an adsorption conveyor belt, which includes an adsorption platform 100 and a conveying device 200.

[0021] The suction table 100 has two parallel, downward-facing suction surfaces 110 located on the same horizontal plane. The conveying device 200 includes two synchronously operating belts 210 that are respectively attached to the two suction surfaces 110.

[0022] Combination Figures 2 to 4 As shown, each belt 210 has adsorption holes 211 spaced apart along the running direction, and each adsorption surface 110 has adsorption grooves 111 spaced apart along the path of the adsorption holes 211.

[0023] Combination Figure 5 and Figure 6 As shown, the suction table 100 forms closed air chambers 120 corresponding to each adsorption surface 110, and jet channels 130 connecting the air chambers 120 to the outside via the adsorption tank 111. With this structure, compressed gas is introduced into the air chambers 120, and the compressed gas is ejected at high speed outward through the jet channel 130, thereby creating a negative pressure in the adsorption tank 111 (according to Bernoulli's fluid principle), thus generating an adsorption force on the belt and the workpiece. The formation of the air chambers 120 and the jet channel 130 is described in prior art CN112919019A, and will not be repeated here.

[0024] In this embodiment, the jet channel 130 is divided into an inner channel 131 located between the gas chamber 120 and the adsorption tank 111, and an outer channel 132 located between the adsorption tank 111 and the outside. The aperture of the inner channel 131 is smaller than that of the outer channel 132. This structure enables the jet channel to generate a high-speed flow, thereby causing the adsorption tank to generate negative pressure suction.

[0025] To ensure structural strength and adequate adsorption force, the adsorption holes 211 and adsorption grooves 111 need to have appropriate lengths, widths, and spacing. Specific dimensions can be obtained through computer simulation and prototype testing. However, it is important to emphasize that the length of the adsorption hole 211 should be greater than the spacing between adjacent adsorption grooves 111. This ensures that during belt operation, the adsorption grooves 111 effectively hold the belt in place, and that each adsorption hole 211 remains connected to the adsorption groove 111, thus guaranteeing the effective adsorption of the workpiece by the adsorption holes 211 throughout the belt's movement. Furthermore, the width of the adsorption hole 211 should be greater than the width of the adsorption groove 111. This ensures that even if the belt deviates from its designated position, the adsorption hole 211 will always remain connected to the adsorption groove 111.

[0026] The transmission device 200 can drive the belt 210 to run along the adsorption plane 110, which is the prior art and is described in the prior art CN112919019A, so it will not be repeated here.

[0027] It should be noted that the suction table 100 can be equipped with multiple air chambers 120 at intervals along each suction plane 110 in a belt-driven operation. Each air chamber 120 can connect to multiple suction tanks 111 and jet channels 130 in a group. That is, a single compressed air source can supply compressed air to multiple air chambers 120 through solenoid valves. Then, each air chamber 120 sprays compressed air into the multiple jet channels 130 connected to it, thereby generating negative pressure suction in the multiple suction tanks 111 connected to it. By controlling the on / off state of the solenoid valve of the corresponding air chamber 120, the suction force generated in the corresponding suction tank 111 can be controlled, thereby controlling the suction and placement of workpieces at the required positions to meet the needs of workpiece picking.

[0028] In this invention, by providing spaced-apart adsorption holes 211 on the belt 210 along the running direction, and spaced-apart adsorption grooves 111 on the adsorption surface 110 along the path traversed by the adsorption holes 211, the belt 210 is not only adsorbed by the adsorption grooves 111 during operation, but also the adsorption grooves 111 communicate with the adsorption holes 211 as they pass through them, thus adsorbing the workpiece. Therefore, only one path of compressed gas needs to be supplied to the adsorption grooves 111 to achieve the function of adsorbing both the belt 210 and the workpiece, eliminating the need for two paths of compressed gas, thereby reducing the use of compressed gas and lowering energy consumption. It is evident that the adsorption conveyor belt of this invention has the advantage of reducing the use of compressed gas and thus lowering energy consumption.
