Description

Technical Field

[0001] The utility model relates to the technical field of paper-plastic mold production and transmission equipment, and particularly relates to an adsorption transmission device and a transmission system. Background Art

[0002] With the development of computer vision, in the field of pulp molding, cameras are gradually used to take pictures and identify to evaluate and detect the production finished products of pulp molding. For example, it is judged whether there are dirt, missing parts, etc. on the surface of the pulp molding product. In order to realize the comprehensive detection of the production finished products of pulp molding, usually after the front side of the product is photographed and detected, the back side of the product also needs to be photographed and detected.

[0003] Based on this, the current mainstream method is to add a flipping device for flipping the product when photographing the back side of the product. However, since the production finished products of pulp molding are usually relatively fragile, during the flipping process, the flipping device is likely to damage the product and also likely to cause the occlusion of the photographed image, thus greatly affecting the subsequent detection and recognition work. Summary of the Utility Model

[0004] The utility model provides an adsorption transmission device and a transmission system to solve the problem that a flipping device needs to be set for photographing the bottom surface of a target product in the prior art.

[0005] To solve the above technical problems, in the first aspect, the technical solution adopted by the utility model is to provide an adsorption transmission device, which includes: an adsorption table, a plurality of first air holes, a conveyor belt and a negative pressure component.

[0006] The adsorption table is provided with at least one negative pressure chamber; the first air holes are located at the bottom of the adsorption table along a first direction and are communicated with the negative pressure chamber; the conveyor belt surrounds the adsorption table along a second direction. Among them, the conveyor belt is also provided with a plurality of second air holes, which can be communicated with the first air holes and are used for adsorbing a target product; the negative pressure component is communicated with the negative pressure chamber and can make the negative pressure chamber in a negative pressure state.

[0007] The beneficial effects brought by the technical solution provided by the utility model compared with the prior art are:

[0008] By setting the adsorption table and the conveyor belt to cooperate to adsorb the target product. Among them, since the paper-plastic molding is made by punching, and as long as there is punching, a plane will be formed. By using the adsorption table and the conveyor belt to cooperate, the target product can be adsorbed and transmitted in an adsorbed state by adsorbing this plane. Among them, the negative pressure chamber inside the adsorption table is in a negative pressure state under the action of the negative pressure component, so as to form an adsorption area for the first air holes communicated with the negative pressure chamber.

[0009] During the conveying process of the conveyor belt, the second air holes will move accordingly. When the second air holes are in communication with the first air holes, they are used to contact the top surface of the target product to adsorb the target product.

[0010] With the above transmission structure, during the photographing and detecting process of the paper-plastic mold, the target product can be transported by contacting the conveyor belt through its top, and then a photographing camera can be arranged on the bottom surface of the transmission device to directly photograph the bottom surface of the target product without being blocked by other devices, etc. Thus, it is possible to achieve all-round photographing and detecting whether there are phenomena such as dirt and omission on the target product.

[0011] In some embodiments, the first air holes and the second air holes are arranged in an array along the second direction, wherein the aperture of the second air holes is larger than that of the first air holes.

[0012] With the above technical solution, when the diameter of the first air holes is smaller than that of the second air holes, the first air holes and the second air holes will form a structure similar to a suction cup, making the adsorption of the target product more stable.

[0013] In some embodiments, a third air hole is further provided at the bottom of the adsorption table along the first direction, and the third air hole is in communication with the negative pressure chamber, wherein the third air hole is used to adsorb the conveyor belt.

The bracket is connected to the adsorption table, and the lifting component is used to drive the adsorption table to approach or move away from the bracket along the first direction.

[0017] With the above technical solution, a lifting mechanism is added to adjust the height of the adsorption table and the conveyor belt thereon, so as to adjust the height difference between the adsorption table and the external transmission device, so that the target product can be smoothly adsorbed from the external transmission device onto the conveyor belt. Among them, the target product contacts the external transmission device through its bottom surface and contacts the conveyor belt through its top surface.

[0018] In some embodiments, the lifting assembly includes a plurality of lifting chains and a driving device. The bracket includes a first bracket and a second bracket. The plurality of lifting chains are respectively connected to the first bracket and the second bracket. Among them, the second bracket is connected to the adsorption table, and the driving device is used to drive the displacement of the lifting chain so that the second bracket approaches or moves away from the first bracket along the first direction.

[0019] With the above technical solution, the lifting chain adjusts the height of the second bracket under the drive of the driving device, that is, adjusts the displacement distance of the adsorption table. Among them, the driving device can be connected to an external electrical device to achieve precise control and automatic regulation of the lifting of the adsorption table.

[0020] In some embodiments, the negative pressure assembly is provided with a plurality of air ducts and a negative pressure pump. The air ducts are communicated with the negative pressure pump. Among them, the air ducts are in one-to-one correspondence and communication with the negative pressure chambers.

[0021] With the above technical solution, the negative pressure assembly further includes a header. The air outlet of the negative pressure pump is communicated with the header, and the air flow is divided into a plurality of air ducts, so that the negative pressure chambers can be in a negative pressure state under the action of the negative pressure pump. Among them, the negative pressure pump has a high negative pressure capacity, and can enable the negative pressure chambers to achieve a higher vacuum degree.

[0022] In some embodiments, the negative pressure assembly further includes a plurality of regulating valves. The regulating valves are arranged on the air ducts and are used to regulate the air flow rate inside the air ducts.

[0023] With the above technical solution, regulating valves corresponding to the negative pressure chambers are provided, so that the negative pressure degree of the corresponding negative pressure chambers can be adjusted by adjusting the air flow rate inside the air ducts.

[0024] In some embodiments, the negative pressure assembly further includes a negative pressure fan and a plurality of air ducts. The air ducts are connected to the negative pressure fan. Among them, the air ducts are also provided with a plurality of regulating valves for regulating the air flow rate inside the air ducts.

[0025] With the above technical solution, the negative pressure fan has the advantages of low cost, simple installation, and easy maintenance.

Among them, the negative pressure assembly further includes a header. The negative pressure fan is connected to the header and divides the air flow into a plurality of air ducts.

[0026] In some embodiments, the present application further provides a transmission system, including the above adsorption conveying device, and further including a transmission table and a photographing device.

[0040] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0041] For the convenience of subsequent description, before describing the specific structure of the adsorption and transfer device, the present application first defines Figure 1 a first direction (X), a second direction (Z), and a third direction (Y). Among them, the first direction is the length direction of the adsorption and transfer device when it is placed normally, for example, the X direction; the second direction is the height direction of the adsorption and transfer device when it is placed normally, for example, the Z direction; the third direction is the width direction of the adsorption and transfer device when it is placed normally, for example, the Y direction. In the present application, the first direction (X), the second direction (Z), and the third direction (Y) are perpendicular to each other.

[0042] It can be understood that the perpendicularity in the present application is not an absolute perpendicularity. The approximate perpendicularity caused by processing errors and assembly errors (for example, the included angle between two structural features is 89.9°) is also within the scope of the perpendicularity in the present application.

[0043] See Figures 1 to 4 as shown Figure 1 shows a three-dimensional structural schematic diagram of an embodiment of an adsorption and transfer device provided by the present application, Figure 2 shows a partial structural schematic diagram of an embodiment of an adsorption and transfer device provided by the present application; Figure 3 shows a three-dimensional structural schematic diagram of an embodiment of the adsorption table 10 of an adsorption and transfer device provided by the present application; Figure 4 shows a schematic diagram of the first air hole 12 and the second air hole 21 of an adsorption and transfer device provided by the present application.

[0044] In some embodiments, the adsorption transfer device includes: an adsorption table 10, a plurality of first air holes 12, a conveyor belt 20, and a negative pressure assembly 30.

[0045] The adsorption table 10 is provided with at least one negative pressure chamber 11; the first air holes 12 are located at the bottom of the adsorption table 10 along a first direction and communicate with the negative pressure chamber 11; the conveyor belt 20 surrounds the adsorption table 10 along a second direction. Among them, the conveyor belt 20 is further provided with a plurality of second air holes 21, and the second air holes 21 can communicate with the first air holes 12 and are used for adsorbing the target product 3; the negative pressure assembly 30 communicates with the negative pressure chamber 11 and can make the negative pressure chamber 11 in a negative pressure state.

[0046] In the embodiments of the present application, the adsorption table 10 and the conveyor belt 20 are arranged in cooperation to adsorb the target product 3.

Among them, the negative pressure chamber 11 inside the adsorption table 10 is in a negative pressure state under the action of the negative pressure assembly 30, so that the first air holes 12 communicating with the negative pressure chamber 11 form an adsorption area. Exemplarily, when transporting paper-plastic dinner bowls, the conveyor belt 20 can form a negative pressure space with the inside of the dinner bowl to firmly transport the paper-plastic dinner bowl.

[0047] Combined with Figure 4 As shown, since the second air holes 21 will move accordingly during the transmission process of the conveyor belt 20, when the second air holes 21 communicate with the first air holes 12, they are used to contact the top surface of the target product 3 to adsorb the target product 3. It can form a suction cup-like structure as shown in Figure 4 As shown. During the photographing and inspection process of the paper-plastic mold, the target product 3 can be transported by contacting the conveyor belt 20 through the top.

For example, two partition plates are arranged to form three negative pressure chambers 11, so that when the target product 3 is conveyed, it can be conveyed in sections. This can avoid excessive energy consumption due to an overly large negative pressure chamber 11.

[0051] In some embodiments, the negative pressure assembly 30 further includes a plurality of regulating valves 34, which are arranged on the air duct 31 and are used to regulate the air flow rate inside the air duct 31.

Exemplarily, the regulating valve 34 can also be arranged at the connection of the branch pipe and the manifold to regulate the air flow rate of the manifold and the branch pipe.

[0053] In some embodiments, the negative pressure assembly 30 further includes a negative pressure fan (not shown in the figure) and a plurality of air ducts 31. The air ducts 31 are connected to the negative pressure fan. Among them, the air ducts 31 are also provided with a plurality of regulating valves 34 for regulating the air flow rate inside the air ducts 31.

[0054] In the embodiments of the present application, the negative pressure fan has the advantages of low cost, simple installation, and easy maintenance. As the negative pressure generating device for the negative pressure chamber 11, it can also ventilate and exchange air in the space where the negative pressure fan is located. Among them, the negative pressure assembly 30 further includes a manifold. The negative pressure fan is connected to the manifold and divides the air flow into a plurality of air ducts 31.

[0055] In some embodiments, in combination with Figure 4 As shown, the first air holes 12 and the second air holes 21 are arranged in an array along the second direction, and the aperture of the second air holes 21 is larger than that of the first air holes 12.

[0056] In the embodiments of the present application, when the diameter of the first air holes 12 is smaller than that of the second air holes 21, and when the first air holes 12 and the second air holes 21 are connected, they can be aligned with the centers or at least partially overlapped, and both can make the adsorption of the target product 3 more stable.

[0057] In combination with Figure 5 As shown, Figure 5 The figure shows a bottom view of an embodiment of the adsorption table 10 of an adsorption and transmission device provided by the present application.
