Description

Technical Field

[0001] The present application relates to the technical field of transportation equipment, and in particular to a belt conveyor device. Background Art

[0002] In the production and manufacturing of batteries, since the thickness of the battery electrode is extremely small, basically in the micron and millimeter level, and the weight of the battery electrode is also very light, the friction between the battery electrode and the belt of the belt conveyor is extremely small. In order to maintain the relative position of the battery electrode and the belt during transportation, a negative pressure groove is usually provided under the belt, and adsorption holes connected to the negative pressure groove are provided on the belt to adsorb the battery electrode through the adsorption holes.

[0003] In the prior art, battery electrode manufacturing equipment needs to perform CCD synchronous detection on the external dimensions of the battery electrode during the battery electrode manufacturing process. When CCD detects the height and width dimensions of the battery electrode, backlight is required to pass through the outer contour of the battery electrode to accurately measure the required dimensions. Therefore, the width of the belt conveyor currently used is smaller than the width of the battery electrode, which will cause part of the battery electrode to protrude outside the transmission belt.

[0004] Since the edge of the negative pressure groove and the fitting surface of the belt cannot reach a completely sealed state during operation, a gap exists. The gap will cause the negative pressure of the negative pressure groove to leak out. The leaked negative pressure will be transmitted to the surface of the belt along the gap. The part of the battery pole protruding out of the belt will be absorbed by the leaked negative pressure, causing the battery pole to deform. At the same time, the edge of the negative pressure groove is relatively fixed and will not move with the belt. During the belt conveying process, the battery pole and the edge of the negative pressure groove will rub against each other, resulting in scratches. In severe cases, the pole will lose powder and affect the quality of the battery cell. The falling debris will also cause secondary pollution to the battery pole and the equipment environment.

[0033] The utility model proposes a belt conveyor 100 for transporting a battery pole piece 200. In the production of batteries, the belt conveyor 100 can be used to transport the battery pole piece 200 to a specified position to improve the automation of battery production. Figures 1 to 4 In an embodiment of the present utility model, the belt conveyor device 100 includes a mounting frame 10, a belt 20 and a negative pressure assembly 30.

[0034] The mounting frame 10 is provided with a negative pressure groove 11 and two isolation grooves 12 along the width direction, and the negative pressure groove 11 and the two isolation grooves 12 are extended along the length direction of the mounting frame 10. The two isolation grooves 12 are respectively located on both sides of the negative pressure groove 11. The mounting frame 10 is also provided with pressure relief holes 121 connected with the two isolation grooves 12.

[0035] The distances between the two isolation grooves 12 and the edges of the negative pressure groove 11 can be the same, that is, the two isolation grooves 12 can be symmetrically arranged on both sides of the negative pressure groove 11, or they can be different. It can be understood that the two side edges of the belt 20 will cover the two isolation grooves 12 respectively. In order to prevent the belt 20 from sinking into the isolation groove 12 when it deviates, the width of the isolation groove 12 is relatively narrow. The utility model does not make specific restrictions on the distance between the isolation groove 12 and the negative pressure groove 11 and the width of the isolation groove 12.

[0036] Considering that the pressure relief hole 121 connected to the isolation groove 12 may affect the battery electrode 200 located on the belt 20, the pressure relief hole 121 can be set in a direction away from the belt 20. Specifically, the pressure relief hole 121 can be set in a horizontal direction away from the mounting frame 10, and the pressure relief hole 121 can also be set in a vertical downward direction. It should be noted that the pressure relief hole 121 is connected to the atmosphere.

[0037] The belt 20 is penetrated by a plurality of adsorption holes 21 , and is wound around the mounting frame 10 , and can move along the length direction of the mounting frame 10 . When part of the belt 20 covers the notches of the negative pressure groove 11 and the two isolation grooves 12 , part of the adsorption holes 21 are connected to the negative pressure groove 11 .

[0038] It can be understood that the belt 20 moves along the length direction of the mounting frame 10, and part of the inner side surface of the belt 20 covers the notches of the negative pressure groove 11 and the two isolation grooves 12, and the outer side surface opposite to the inner side surface of the belt 20 is used to transport the battery pole piece 200. The plurality of adsorption holes 21 are usually evenly distributed on the belt 20, so that the outer side surface of the belt 20 can generate a uniform adsorption force, and the shape of the plurality of adsorption holes 21 is usually circular, so that the adsorption force can act evenly on the battery pole piece 200.

[0039] The negative pressure assembly 30 is connected to the negative pressure groove 11, and forms a negative pressure in the negative pressure groove 11, so that the belt 20 can adsorb the battery pole piece 200 through some adsorption holes 21. The negative pressure assembly 30 may include an air pump for sucking air. The negative pressure assembly 30 sucks air from the negative pressure groove 11 so that the negative pressure groove 11 can form a negative pressure. The belt 20 can convert the negative pressure into an adsorption force through the adsorption holes 21 to adsorb the battery pole piece 200 to the surface of the belt 20.

[0040] Through the above technical scheme, the mounting frame 10 is provided with a negative pressure groove 11 and two isolation grooves 12 along the width direction. The two isolation grooves 12 are respectively located on both sides of the negative pressure groove 11. The mounting frame 10 is also provided with pressure relief holes 121 connected with the two isolation grooves 12. When part of the belt 20 covers the notches of the negative pressure groove 11 and the two isolation grooves 12, part of the adsorption holes 21 of the belt 20 are connected with the negative pressure groove 11. With such arrangement, the two side edges of the belt 20 will respectively cover the two isolation grooves 12. When the negative pressure of the negative pressure groove 11 leaks, the leaked negative pressure will leak from the isolation groove 12 adjacent to the negative pressure groove 11, and the isolation groove 12 can leak into the atmosphere through the pressure relief hole 121, that is, the air flow flows from the isolation groove 12 from the gap between the belt 20 and the mounting frame 10 to the negative pressure groove 11. Compared with the prior art, the leaked negative pressure is avoided from leaking from the gap between the edge of the belt 20 and the mounting frame 10 to the surface of the belt 20, thereby ensuring that the battery electrode 200 is not affected by the leaked negative pressure, thereby avoiding friction between the battery electrode 200 and the mounting frame 10, so as to improve the quality of the battery electrode 200.

[0041] In some examples, such as Figures 1 to 4 As shown, the pressure relief hole 121 is formed on the peripheral side of the mounting frame 10, and the pressure relief hole 121 is also extended along the length direction of the mounting frame 10. Specifically, the pressure relief hole 121 is arranged in the horizontal direction in the direction away from the mounting frame 10. The number of the pressure relief holes 121 can be multiple, and multiple pressure relief holes 121 can be arranged at intervals according to the length of the isolation groove 12, and the multiple pressure relief holes 121 can be arranged at uniform intervals, so that the negative pressure leaked from the negative pressure groove 11 can be uniformly released into the atmosphere.

[0042] Such a configuration makes the pressure relief hole 121 in an elongated strip shape, which can better release the negative pressure leaked from the negative pressure groove 11 into the atmosphere, facilitates the processing of the pressure relief hole 121, and also makes the mounting frame 10 lightweight.

[0043] In some examples, such as Figure 3 and Figure 5As shown, the negative pressure tank 11 is further provided with a support portion 13, and the support portion 13 is in contact with the inner line of the belt 20 to support the belt 20. The support portion 13 may include a plurality of support ribs, and the plurality of support ribs may be arranged at intervals in the horizontal direction. Specifically, the plurality of support ribs may be arranged at intervals along the width direction of the mounting frame 10, and the plurality of support ribs may also be arranged at intervals along the length direction of the mounting frame 10, and the plurality of support ribs may also be arranged staggered on the horizontal plane.

[0044] Such arrangement is intended to support the belt 20 in the negative pressure groove 11 through the support part 13 to prevent the belt 20 from sinking into the negative pressure groove 11 due to gravity or excessive weight of the goods carried, resulting in an uneven outer surface of the belt 20. The support part 13 is in contact with the inner line of the belt 20, which can reduce the obstruction of the adsorption holes 21 on the belt 20 by the support part 13 to avoid loss of suction.

[0045] In some examples, such as Figure 3 and Figure 5 As shown, the support portion 13 includes a plurality of support ribs sequentially arranged along the width direction of the mounting frame 10 , and the plurality of support ribs are also extended along the length direction of the mounting frame 10 , and one side of the plurality of support ribs abuts against the inner side of the belt 20 .

[0046] Such a configuration can further reduce the friction between the support portion 13 and the belt 20 , making the movement of the belt 20 smoother. The plurality of support ribs are arranged in sequence along the width direction of the mounting frame 10 , and each support rib can also be captured between the two adsorption holes 21 .

[0047] In some examples, such as Figure 3 and Figure 5 As shown, a plurality of supporting ribs are connected to the bottom wall of the negative pressure groove 11 on the side away from the belt 20 to separate the negative pressure groove 11 into a plurality of sub-negative pressure grooves. The plurality of sub-negative pressure grooves are all extended along the length direction of the mounting frame 10, and each sub-negative pressure groove is connected to the negative pressure assembly 30.

[0048] With such arrangement, multiple supporting ribs are connected to the bottom wall of the negative pressure groove 11 to enhance the stability of the overall structure to better support the belt 20 , and spacing the negative pressure groove 11 to form multiple sub-negative pressure grooves can better disperse the negative pressure formed by the negative pressure assembly 30 .

[0049] In some examples, such as Figures 3 to 5 As shown, the negative pressure assembly 30 includes a base 31 and an air pump. The base 31 is provided with an air groove 32. The side of the mounting frame 10 away from the belt 20 covers the notch of the air groove 32 to form a sealed air chamber 33. The bottom wall of the negative pressure groove 11 is provided with an air hole 111 connected to the air chamber 33. The air pump is connected to the air chamber 33 and is used to suck the gas in the air chamber 33 to form a negative pressure in the negative pressure groove 11.

[0050] In this way, the negative pressure assembly 30 can evenly act on the negative pressure groove 11 through the base 31, and the negative pressure groove 11 is isolated from the air pump through the air chamber 33 to prevent some debris on the belt 20 from affecting the normal operation of the air pump. Specifically, the negative pressure groove 11 is spaced apart to form a plurality of sub-negative pressure grooves in combination with the above-mentioned plurality of supporting ribs, and the bottom wall of each sub-negative pressure groove is provided with an air hole 111 connected to the air chamber 33.

[0051] In some examples, such as Figure 3 and Figure 5 As shown, an exhaust port 34 communicating with the air chamber 33 is provided on the peripheral side of the base 31 , and the air pump is connected with the air chamber 33 through the exhaust port 34 .

[0052] With such arrangement, the air pump can be arranged outside the base 31 through the exhaust port 34 , and the air pump can be connected to the exhaust port using an air pipe, which facilitates the installation of the negative pressure assembly 30 .

[0053] In some examples, such as Figures 3 to 5 As shown, the mounting frame 10 is provided with ribs 14 on both sides in the width direction, and the two ribs 14 are extended along the length direction of the mounting frame 10 to limit the belt 20 from deviating to both sides of the mounting frame 10 .

[0054] With such arrangement, the two side guards 14 can limit the belt 20 from deviating toward the two sides of the mounting frame 10 during movement, thereby preventing the edge of the belt 20 from escaping from the isolation groove 12 and causing the isolation groove 12 to lose its function.

[0055] In some examples, such as Figure 1 and Figure 5 As shown, the belt conveyor 100 further includes a driving roller set 40 , which is transmission-connected to the belt 20 to drive the belt 20 to move along the length direction of the mounting frame 10 .

[0056] In this arrangement, the belt conveyor 100 drives the belt 20 to move through the driving roller group 40 to achieve the purpose of conveying the battery electrode 200. Specifically, the driving roller group 40 may include a driving roller and a plurality of driven rollers, so that the moving path of the belt 20 is limited through the interaction of the plurality of driven rollers, and the driving roller is used to drive the movement of the belt 20.

[0057] In some examples, such as Figure 1 As shown, the belt conveyor 100 also includes two pallets 50 and a shooting module. The two pallets 50 are respectively arranged on both sides of the mounting frame 10, and the upper surfaces of the two pallets 50 are arranged flush with the surface of the belt 20 used to transport the electrode. The belt 20 is provided with a shooting station, and the shooting module is arranged above the shooting station. The shooting module is used to collect image information of the battery electrode 200.

[0058] The support plate 50 can be made of a light-transmitting wear-resistant material, or can be made of a light-reflecting wear-resistant material. The image information of the battery pole piece 200 collected by the camera module includes but is not limited to the height and width dimensions of the battery pole piece.

[0059] With such arrangement, the battery pole piece 200 can be prevented from being separated from the belt 20 by the bearing function of the two support plates 50, and the image information of the battery pole piece 200 can be collected by the shooting module, thereby improving the automated production efficiency and quality of the battery pole piece.

[0060] The above description is only an optional embodiment of the present application, and does not limit the patent scope of the present application. All equivalent structural transformations made by using the contents of the present application specification and drawings under the inventive concept of the present application, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present application.
