Description

Technical Field

[0001] The utility model relates to a positive and negative pressure conveying mechanism for battery wafers of a screen printing machine, belonging to the technical field of screen printing machines. Background Art

[0002] In the existing technology, the battery wafer conveying mechanism of the screen printing machine has the problem of small friction between the battery wafer and the conveyor belt, resulting in the inability to increase the conveying speed, that is, the conveying time of the battery wafers within a unit distance cannot be shortened, and thus the overall line CT cannot be improved. Content of the Utility Model

[0003] The positive and negative pressure conveying mechanism for battery wafers of the screen printing machine proposed by the utility model aims to overcome the above-mentioned deficiencies existing in the prior art and increase the friction between the battery wafer and the conveyor belt.

[0004] The technical solution of the utility model: A positive and negative pressure conveying mechanism for battery wafers of a screen printing machine, whose structure includes a positive pressure mechanism and a negative pressure mechanism respectively arranged above and below the conveyor belt, and the battery wafers are conveyed on the conveyor belt. Blow air above the battery wafers to apply positive pressure to the battery wafers, so that the pressure between the battery wafers and the conveyor belt becomes larger, increasing the friction between the battery wafers and the conveyor belt. At the same time, a negative pressure is formed between the conveyor belt and the battery wafers through an adsorption method, so that the battery wafers are adsorbed on the conveyor belt, further increasing the friction between the battery wafers and the conveyor belt.

[0005] Preferably, the positive pressure mechanism includes air blowing pipes arranged at intervals above the conveyor belt along the length direction. The bottom of the air blowing pipes is evenly provided with air blowing holes facing the top surface of the conveyor belt. The air blowing pipes are externally connected to a positive pressure air blowing device through positive pressure connectors. The middle part of the air blowing pipes passes through a support frame, and the support frame is fixed on the machine frame. The positive pressure enters the inner cavity of the air blowing pipes through the positive pressure connectors and blows and presses down on the top surface of the battery wafers on the conveyor belt from the air blowing holes, which can increase the friction between the battery wafers and the conveyor belt and help improve the conveying speed.

[0006] Preferably, the negative pressure mechanism includes a support arranged along the length direction of the bottom surface of the upper part of the conveyor belt. A negative pressure channel is arranged inside the support, and a number of air extraction holes facing the bottom surface of the upper part of the conveyor belt are evenly opened on the surface. The negative pressure channel is externally connected to a negative pressure air extraction device through a negative pressure connector on the side of the support. A number of waist-shaped holes corresponding to the positions of the air extraction holes are opened on the conveyor belt. The negative pressure enters the negative pressure channel and can act on the battery wafers through the waist-shaped holes of the conveyor belt.

[0007] The advantages of the utility model: The structure is reasonably designed. By applying positive pressure on the upper side and negative pressure on the lower side, the friction between the battery wafers and the conveyor belt becomes larger, so that the conveying speed of the battery wafers can be increased, which helps to shorten the overall machine CT time and improve the production capacity. The increase in the friction between the battery wafers and the conveyor belt can also effectively prevent the slipping phenomenon of the battery wafers due to speed increase, and improve the conveying accuracy and speed.

Detailed Description of the Preferred Embodiments

[0013] The present utility model will be further described in detail below in conjunction with the embodiments and specific implementation manners.

[0014] As Figures 1 - 4 shown, a positive and negative pressure conveying mechanism for battery wafers of a screen printing machine includes a positive pressure mechanism and a negative pressure mechanism respectively arranged above and below the conveyor belt 1. The battery wafer 11 is conveyed on the conveyor belt 1. The positive pressure mechanism includes air blowing pipes 7 arranged at intervals above the conveyor belt 1 along the length direction. The bottom of the air blowing pipes 7 is evenly provided with air blowing holes 8 facing the top surface of the conveyor belt 1. The air blowing pipes 7 are externally connected to a positive pressure blowing device through the positive pressure connectors 9. The middle of the air blowing pipes 7 passes through the support frame 10, and the support frame 10 is fixed on the machine frame. The negative pressure mechanism includes a bracket 3 arranged along the length direction of the bottom surface of the upper part of the conveyor belt 1. A negative pressure channel 4 is arranged inside the bracket 3 and a plurality of air extraction holes 5 facing the bottom surface of the upper part of the conveyor belt 1 are evenly opened on the surface. The negative pressure channel 4 is externally connected to a negative pressure extraction device through the negative pressure connector 6 on the side surface of the bracket 3. A plurality of waist holes 2 corresponding to the positions of the air extraction holes 5 are opened on the conveyor belt 1.

[0015] Specifically, as Figure 1 , 2 shown, during processing, the air blowing pipes 7 are drilled in the center, and then the two ends are blocked and sealed. Air blowing holes 8 are drilled on the side directly opposite to the conveyor belt 1. The air blowing holes 8 are communicated with the holes in the center of the air blowing pipes 7. Positive pressure connectors 9 for air intake are arranged on the side surface. Positive pressure enters the inner cavity of the air blowing pipes 7 through the positive pressure connectors 9 and blows and presses down on the top surface of the battery wafers 11 on the conveyor belt 1 from the air blowing holes 8, which can increase the friction between the battery wafers 11 and the conveyor belt 1 and help improve the conveying speed.

[0016] As shown Figure 3 , 4 When processing, a hole is drilled in the center of the bracket 3, and then both ends are blocked and sealed. A groove is formed on the contact surface with the conveyor belt 1 to form a negative pressure channel 4 and an air extraction hole 5. The air extraction hole 5 is connected to the negative pressure channel 4 in the center. A negative pressure connector 6 for negative pressure extraction is provided on the side. Negative pressure enters the negative pressure channel 4, and the conveyor belt 1 is improved. Waist-shaped holes 2 are processed at equal intervals on the conveyor belt, so that the negative pressure in the bracket 3 can act on the battery sheet 11 through the waist-shaped holes 2 of the conveyor belt 1.

[0017] According to the above structure, air is blown above the battery sheet 11 to apply a positive pressure to the battery sheet 11, so that the pressure between the battery sheet 11 and the conveyor belt 1 becomes larger, increasing the friction between the battery sheet 11 and the conveyor belt 1. At the same time, a negative pressure is formed between the conveyor belt 1 and the battery sheet 11 by adsorption, so that the battery sheet 11 is adsorbed on the conveyor belt 1, further increasing the friction between the battery sheet 11 and the conveyor belt 1.

[0018] All the above components are prior arts, and those skilled in the art can use any models and existing designs that can achieve their corresponding functions.

[0019] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the creative concept of the present invention, several deformations and improvements can be made, and these all belong to the protection scope of the present invention.
