Description

[0002] In the integrated cutting and stacking equipment for lithium battery electrodes, vacuum belt conveyors are typically used to transport the electrodes. In the vacuum belt conveyor system of related technologies, the single-section conveyor usually adopts a single-cavity vacuum design, that is, the air pressure in the entire internal cavity of the conveyor is consistent.

[0003] However, the electrode requires varying suction force at different stages of transport on the conveying device. For example, a larger negative pressure suction force is needed at the transport position to prevent electrode displacement; the suction force needs to be appropriately reduced at the pick-up position to facilitate pick-up by the suction cup; the negative pressure of the two conveying sections may differ, and the negative pressure suction force experienced by the electrode at the feed position entering the conveying device needs to be compatible with the previous connected conveying section. Related conveying devices cannot meet the differentiated requirements of negative pressure suction force for the electrode at different stages of transport. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0031] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0032] like Figures 1 to 4As shown, this application provides a vacuum belt conveyor device, including a housing 1, a vacuum belt 2 wound around the housing 1, and a drive member 3 for driving the vacuum belt 2 to move around the housing 1. The inner cavity of the housing 1 can form a negative pressure, and through holes are provided on the upper surface of the housing 1 and the vacuum belt 2, so that when the electrode is conveyed on the vacuum belt 2, under the action of the negative pressure environment in the inner cavity of the housing 1, the through holes on the upper surface of the housing 1, and the through holes on the vacuum belt 2, the vacuum belt 2 can adsorb the electrode.

[0033] Among them, such as Figure 4 As shown, the inner cavity of the housing 1 is provided with a wind baffle, which divides the inner cavity of the housing 1 into multiple chambers. The multiple chambers are arranged sequentially along the conveying direction of the vacuum belt 2. The housing 1 is provided with an exhaust port 11, which communicates with the chambers. The wind baffle is rotatably connected to the housing 1 and can rotate relative to the housing 1. The housing 1 is provided with a rotating component for driving the wind baffle to rotate.

[0034] The inner cavity of the housing 1 is divided into multiple chambers arranged sequentially along the conveying direction of the vacuum belt 2 by a baffle plate, and an exhaust port 11 connected to the chamber is provided to create negative pressure in the chamber. The chambers on both sides of the baffle plate are connected through the gap between the baffle plate and the housing 1. The relative angle between the baffle plate and the housing is adjusted by a rotating component, thereby flexibly controlling the cross-sectional area of ​​the airflow channel between adjacent chambers on both sides of the baffle plate, and realizing the adjustment of the negative pressure value of the chambers on both sides of the baffle plate. Thus, the required adsorption pressure is formed in the feeding section, conveying section and picking section of the vacuum belt conveyor, which can meet the three-stage differentiated needs of the electrode at the conveying position for higher adsorption force, at the picking position for lower adsorption force, and at the feeding position for moderate adsorption force.

[0035] In some embodiments, such as Figures 1 to 4 As shown, the windbreak includes a first windbreak 4 and a second windbreak 5. The two windbreaks divide the inner cavity of the housing 1 into three chambers, which are arranged sequentially along the conveying direction of the vacuum belt 2. Figure 2 As shown in the diagram, the vacuum belt 2 moves clockwise on the housing 1, that is, in... Figures 2 to 4 In this configuration, the vacuum belt 2 moves from left to right on the upper surface of the housing 1, thus conveying the electrode sheets from left to right. Two baffles divide the inner cavity of the housing 1 into three chambers arranged sequentially from left to right. Figure 2 and Figure 4 As shown, the three chambers correspond to the delivery segment a, the conveying segment b, and the take-up segment c of the vacuum belt conveyor, respectively.

[0036] In some other embodiments, the number of wind deflectors is not limited to two, but can also be three, four, etc. Of course, only one wind deflector can be provided, which is only used to control the adsorption pressure at the feeding position or the taking position.

[0037] like Figure 4 As shown, the exhaust port 11 is connected to the chamber between the two baffles, that is, the exhaust port 11 is connected to the chamber located in the conveying section b. Air is drawn from the exhaust port 11 by the exhaust equipment, thereby creating a negative pressure inside the housing 1. The baffles are rotatably connected to the housing 1 and can rotate relative to the housing 1. The housing 1 is provided with rotating components for driving the baffles to rotate; that is, both the first baffle 4 and the second baffle 5 are rotatably connected to the housing 1. The housing 1 is provided with a first rotating component 6 for driving the first baffle 4 to rotate, and a second rotating component 7 for driving the second baffle 5 to rotate.

[0038] The inner cavity of the housing 1 is divided into three chambers arranged sequentially along the conveying direction of the vacuum belt 2 by two baffles. An exhaust port 11 connected to the middle chamber is provided to create negative pressure in the middle chamber. The two side chambers can form air pressures of different magnitudes than the middle chamber through the gap between the baffles and the housing 1. The relative angle between the baffles and the housing 1 can be adjusted by rotating the component, thereby flexibly controlling the cross-sectional area of ​​the airflow channel between adjacent chambers and adjusting the negative pressure value of the two side chambers. This allows the required adsorption pressure to be formed in the feeding segment a, the conveying segment b, and the taking segment c of the vacuum belt conveyor, satisfying the three-stage differentiated needs of the electrode at the conveying position (high adsorption force), the taking position (low adsorption force), and the feeding position (moderate adsorption force).

[0039] In some embodiments, the rotation axis of the baffle is perpendicular to the conveying direction of the vacuum belt 2. Specifically, such as... Figure 4 As shown, the rotation axes of both baffles are perpendicular to the plane of the paper. The initial state is when the baffles are vertical, with a rotation angle of 0°. The baffles can separate adjacent chambers; specifically, when the first baffle 4 is vertical, it separates the chamber for sending segment a from the chamber for conveying segment b, and the pressure in the chamber for sending segment a is close to atmospheric pressure. When the second baffle 5 is vertical, it separates the chamber for taking segment c from the chamber for conveying segment b, and the pressure in the chamber for taking segment c is also close to atmospheric pressure. By rotating the baffles by a rotating component, the vacuum speed of the chamber for sending segment a or taking segment c can be adjusted accordingly, allowing the chamber for sending segment a or taking segment c to reach the required negative pressure value. This, in turn, allows the vacuum belt for sending segment a or taking segment c to achieve the required negative pressure adsorption force on the electrode.

[0040] In some embodiments, such as Figure 4As shown, the first windbreak plate 4 and the second windbreak plate are arranged sequentially along the conveying direction of the vacuum belt 2, and the exhaust port 11 is set close to the first windbreak plate 4.

[0041] By positioning the exhaust port 11 closer to the first baffle plate 4, the chamber for sending fragment a is closer to the exhaust port 11. When both baffle plates are fully open, the chamber for sending fragment a can obtain a larger negative pressure faster than the chamber for taking fragment c. Therefore, the chamber for sending fragment a has a stronger adsorption capacity for the electrode than the chamber for taking fragment c. The chamber for taking fragment c is farther from the exhaust port 11. By adjusting the angle of the two baffle plates, the vacuuming speed of the chamber for taking fragment c and the chamber for sending fragment a can be controlled, so that the air pressure in the chamber for sending fragment a is lower than that in the chamber for taking fragment c.

[0042] In some embodiments, such as Figure 4 As shown, the multiple chambers include a first chamber 12, a second chamber 13, and a third chamber 14. The first chamber 12, the second chamber 13, and the third chamber 14 are arranged sequentially along the conveying direction of the vacuum belt. The second chamber 13 is located between the first windbreak 4 and the second windbreak 5. The first chamber 12 is located on the side of the first windbreak 4 away from the second chamber 13, and the third chamber 14 is located on the side of the second windbreak 5 away from the second chamber 13. The exhaust port 11 is connected to the second chamber 13.

[0043] The first chamber 12 is for delivering segment a, the second chamber 13 is for delivering segment b, and the third chamber 14 is for taking segment c. The exhaust port 11 is connected to the second chamber 13. The vacuuming speed of the first chamber 12, i.e. the pressure of the first chamber 12, is controlled by adjusting the angle of the first baffle 4. The vacuuming speed of the third chamber 14, i.e. the pressure of the third chamber 14, is controlled by adjusting the angle of the second baffle 5. Thus, the adsorption pressure of delivering segment a and taking segment c are controlled respectively.

[0044] In some other embodiments, the number of chambers is not limited to three chambers; there may also be four, five, or other chambers. Of course, the number of chambers may also be two, with the two chambers being the chamber for conveying section b and the chamber for conveying segment a, or the two chambers being the chamber for conveying section b and the chamber for picking up segment c, controlling only the adsorption pressure at the delivery or picking position.

[0045] In some embodiments, both rotating components are adjustment knobs mounted on the housing 1, and the end of the windshield is connected to the adjustment knob. An angle scale value can be set on the adjustment knob, so that the operator can easily rotate the windshield to the required angle.

[0046] In some embodiments, the outer wall of the housing 1 is provided with an exhaust pipe 8 that communicates with the exhaust port 11. The exhaust pipe 8 is used to connect to an external exhaust device.

[0047] In some embodiments, such as Figures 1 to 4 As shown, the vacuum belt conveyor also includes a support frame located at the bottom of the housing 1. A tensioning roller is rotatably mounted on the support frame, and a rotating roller 10 is mounted on the housing 1. Both the tensioning roller and the rotating roller 10 abut against the inner surface of the vacuum belt 2. The support frame supports the housing 1. The support frame includes a first support frame 20 and a second support frame 30, which are spaced apart from each other. The tensioning roller enables the vacuum belt 2 to be tensioned. During movement, the vacuum belt 2 drives the tensioning roller and the rotating roller 10 to rotate, generating rolling friction. A rotating roller 10 is located at each of the four corners of the housing 1.

[0048] In some embodiments, such as Figure 1 and Figure 2 As shown, the support frame includes a first support frame 20 and a second support frame 30. The driving member 3 is disposed on the first support frame 20. A rotating arm 40 is rotatably disposed on the second support frame 30, and a tensioning roller 9 is rotatably disposed on the rotating arm 40. By rotating the rotating arm 40, the tilt angle of the rotating arm 40 can be adjusted, thereby adjusting the tension of the tensioning roller 9 on the vacuum belt 2.

[0049] In some embodiments, the rotating arm 40 and the second support frame 30 are locked together by a locking member. Specifically, the locking member may be a bolt, and the second support frame 30 may have a plurality of threaded holes spaced circumferentially around the rotation axis of the rotating arm 40. After the rotating arm 40 is rotated to a certain angle, the bolt can be threaded through the rotating arm 40 and locked into the threaded hole, thereby fixing the rotating arm 40 and the second support frame 30.

[0050] In some embodiments, such as Figure 1 and Figure 2 As shown, the second support frame 30 includes a first bracket 31 and a second bracket 32. The first bracket 31 and the second bracket 32 ​​are arranged vertically at intervals. The first bracket 31 is connected to the bottom of the housing 1. The first bracket 31 is provided with a slot 311. The second bracket 32 ​​is rotatably provided with a pressing rod 50, which can be engaged with the slot 311.

[0051] Specifically, the gap between the first bracket 31 and the second bracket 32 ​​can be used to assemble and disassemble the vacuum belt 2. After the vacuum belt 2 is installed between the first bracket 31 and the second bracket 32, the first bracket 31 will vibrate during the high-speed movement of the tensioned vacuum belt 2 due to the gap between the first bracket 31 and the second bracket 32. By rotating the clamping rod 50 and locking the clamping rod 50 into the slot 311, the first bracket 31 and the second bracket 32 ​​are connected as one unit, thereby preventing the first bracket 31 from vibrating.

[0052] In some embodiments, in order to better disassemble and assemble the belt, reduce the size of the transmission device, and make its structure more compact, the drive component 3 is selected as an external rotor DD motor.

[0053] In some embodiments, such as Figure 2 As shown, the drive component 3 is placed on the first support frame 20. Tensioning rollers are also provided on the left and right sides of the drive component 3 on the first support frame 20. The tensioning roller on the right side of the drive component 3 is the first tensioning roller, the tensioning roller on the left side of the drive component 3 is the second tensioning roller, and the tensioning roller 9 provided on the rotating arm 40 is the third tensioning roller.

[0054] To facilitate the replacement of the vacuum belt 2, three tensioning rollers are installed. The first and second tensioning rollers are fixed in position, while the angle of the third tensioning roller is adjustable. Loosen the fixing bolts of the first and second tensioning rollers and the rotating arm 40, loosen the clamping rod 50, and insert the vacuum belt 2. At this time, the vacuum belt 2 is in a slack state. Secure the first and second tensioning rollers onto the first support frame 20 using the support rod and tighten them with bolts. Then adjust the third tensioning roller to a suitable angle and tighten it. Finally, lock the clamping rod 50 into the slot 311 and tighten it. The vacuum belt 2 is now installed. To remove the vacuum belt 2, loosen the first tensioning roller, the second tensioning roller, the rotating arm 40, and the clamping rod 50 in sequence, and then remove the belt.

[0055] like Figure 1 and Figure 2 As shown, the vacuum belt conveyor also includes a dust removal brush 60 located below the housing 1. The dust removal brush 60 is used to clean the vacuum belt 2. The dust removal brush 60 is located between the first support frame 20 and the second support frame 30 and is in contact with the outer surface of the vacuum belt 2.
