A cylindrical battery manufacturing apparatus and manufacturing process

Abstract

This invention relates to the field of cylindrical lithium battery manufacturing technology, and discloses a cylindrical battery manufacturing apparatus and process, including a cleaning device and a drying device. The cleaning device has a discharge channel inclined at its left end, on which several groups of cylindrical batteries are arranged. An intermittent discharge device is located on the right side of the discharge channel. The cylindrical battery manufacturing apparatus and process of this invention features a battery rolling structure. A uniform-speed motor drives a large rubber wheel to rotate slowly clockwise, and a chain structure drives a smaller rubber wheel to rotate synchronously in the same direction. This causes the battery, which has frictional contact with the rubber surface, to rotate irregularly between the two. During rotation, several sets of nozzles in the cleaning seat first spray corrosion inhibitor onto the battery, followed by clean water, for a complete cleaning. Individual rolling cleaning improves the cleaning effect, is suitable for different working conditions, and offers better application prospects.

Description

Technical Field

[0001] This invention relates to the field of cylindrical lithium battery manufacturing technology, and in particular to a cylindrical battery manufacturing apparatus and manufacturing process. Background Technology

[0002] Cylindrical lithium batteries are divided into three different combination systems: lithium cobalt oxide, lithium manganese oxide, and ternary materials. Each of the three material systems has its own advantages. The battery casing is divided into two types: steel casing and polymer casing. This invention mainly uses steel casing. Cylindrical lithium batteries are widely used in: laptops, digital cameras, lighting fixtures, toys, power tools, portable mobile energy and other fields.

[0003] The manufacturing process of cylindrical lithium batteries includes slurry preparation, coating, rolling, slitting, winding, casing, electrolyte injection, welding, pressing, sealing, multiple cleaning processes, drying, oiling, heat shrinking, and coding. Among these processes, the existing equipment and processes for cleaning and heat shrinking have the following technical drawbacks: First, during the processing of cylindrical batteries within this range, the batteries move in a concentrated manner, making them prone to collisions and compression, and some may be missed, affecting the processing effect. Second, cleaning requires multiple nozzle cleanings, and the used nozzles are not recycled, wasting water and corrosion inhibitors. Third, drying the batteries with hot air requires a continuous supply of hot air to maintain the temperature, and the heat cannot be recovered, resulting in low thermal efficiency. Fourth, an additional oiling process is required after drying, making the process complex. Based on the commonalities between the two processes, it is reasonable to believe that they can be combined.

[0004] In summary, considering that existing facilities cannot meet the needs of operation, we propose a cylindrical battery manufacturing device and manufacturing process. Summary of the Invention

[0021] As a preferred embodiment of the cylindrical battery manufacturing apparatus and manufacturing process described in this invention, the left end of the cleaning device is connected to the cylindrical battery assembly line.

[0022] As a preferred embodiment of the cylindrical battery manufacturing apparatus and manufacturing process described in this invention, a support base is provided at the left end of the drying device, and the support base is located at the bottom of the cleaning device.

[0024] As a preferred embodiment of the cylindrical battery manufacturing apparatus and manufacturing process described in this invention, wherein the right end of the drying apparatus is connected to a heat shrink sleeve production line.

[0025] A cylindrical battery manufacturing process includes the following steps.

[0026] S1: Complete batteries with caps assembled at the cylindrical battery assembly line are continuously transported by belt to the discharge channel and arranged. They are blocked by the baffle of the feeding plate. By starting the rotary motor, the rotating rod drives the feeding plate to rotate 90 degrees counterclockwise, allowing a group of batteries to enter the receiving surface of the feeding plate and be temporarily stored. Then the rotating rod drives the feeding plate to rotate 90 degrees clockwise, and the batteries in the receiving surface roll down and enter the top plane of the washing slide. The intermittent feeder operates in this cycle, allowing each group of batteries to be discharged individually.

[0027] S2: Then the battery rolls down the rinsing slide. During the rolling process, the liquid inlet pipe draws back the mixed liquid in the liquid tank and enters the rinsing pipe. It drips down from several sets of rinsing holes, allowing the passing battery to undergo the initial rinsing to remove oil stains and dust from the battery. The dripping liquid also cleans the rinsing slide.

[0028] S3: The battery then falls into the battery rolling structure. By starting the constant speed motor, the large rubber wheel is slowly rotated clockwise through the reduction of large and small gears. Then, the small rubber wheel is rotated synchronously in the same direction through the chain structure. This causes the battery, which has frictional contact with the rubber surface, to rotate irregularly between the two. During the rotation, several sets of nozzles in the cleaning seat spray corrosion inhibitor onto the battery first, and then spray clean water for a second cleaning. The cleaning mixture flows into the return tank through the return pipe for later use. When the large rubber wheel rotates one revolution, the push plate pushes the battery out from the top of the large rubber wheel.

[0029] S4: After being cleaned from the battery rolling structure, the batteries are transferred to the first belt conveyor and transported from left to right into the left end of the drying roller mechanism. Several sets of drying rollers rotate clockwise synchronously, causing the batteries to tumble. During the tumbling process, the batteries come into full contact with the absorbent fabric layer of the drying rollers, thereby absorbing the moisture and achieving the drying effect. At the same time, high-temperature steam passes through the hollow roller body of each set of drying rollers at regular intervals, which can heat the entire drying roller and dry the damp absorbent fabric layer.

[0030] S5: After drying, the battery enters the second belt conveyor and moves to the right. After the battery is corrected to be horizontal, it enters the left end of the oiling mechanism. The oiling mechanism and the drying roller mechanism are connected by a chain structure and operate synchronously. Several sets of oiling rollers rotate clockwise synchronously, which causes the battery to tumble to the right. During the tumbling process, the battery comes into full contact with the coating rod and is evenly coated with anti-rust oil. As the coating rod rotates, it will come into contact with the anti-rust oil in the oil supply tank, ensuring that there is enough oil on the coating rod. After oiling, the battery is transferred to the heat shrink sleeve production line for sleeve assembly.

[0031] This invention provides an improved cylindrical battery manufacturing apparatus and process, which, compared with the prior art, have the following significant improvements and advantages:

[0032] (1) Design an intermittent feeder. By starting the rotary motor group, the rotating rod drives the feeding plate to rotate 90 degrees counterclockwise, allowing a group of batteries to enter the receiving surface of the feeding plate and be temporarily stored. Then the rotating rod drives the feeding plate to rotate 90 degrees clockwise, and the batteries in the receiving surface roll down and enter the top plane of the rinsing slide. The intermittent feeder operates in this cycle, allowing each group of batteries to be fed separately, thereby ensuring that each group of batteries has a certain movement interval during the subsequent processing and does not interfere with each other.

[0033] (2) Design a battery rolling structure. By starting a uniform speed motor, the large rubber wheel is driven to rotate slowly clockwise. Then, the small rubber wheel is driven to rotate synchronously in the same direction through a chain structure. This causes the battery, which has frictional contact with the rubber surface, to rotate irregularly between the two. During the rotation, several sets of nozzles in the cleaning seat spray corrosion inhibitor onto the battery first, and then spray clean water for full-body cleaning. Individual rolling cleaning improves the cleaning effect.

[0034] (3) In (2), the mixture flows into the return tank through the return pipe. The mixture in the return tank is drawn in by the inlet pipe and enters the rinsing pipe. It drips down from several sets of rinsing holes, allowing the passing batteries to undergo the first rinse, removing oil stains and dust from the batteries. The cleaning solution can be reused, reducing waste and production costs. The dripping solution will also clean the rinsing slide, preventing stains from remaining and affecting the movement of the batteries. (2) and (3) work together to improve the cleaning effect.

[0035] (4) After cleaning, the battery is transferred from the battery rolling structure to the first belt conveyor and transported from left to right into the left end of the drying roller mechanism. Several sets of drying rollers rotate clockwise synchronously, which causes the battery to tumble. During the tumbling process, the battery comes into full contact with the absorbent cloth layer of the drying roller and is thus absorbed to achieve the drying effect. At the same time, high-temperature steam passes through the hollow roller body of each set of drying rollers at regular intervals, which can heat the entire drying roller and dry the damp absorbent cloth layer. The high-temperature steam flows unidirectionally in the entire roller group, making full use of its heat. The high-temperature steam will enter the heat shrink sleeve production line through the high-temperature steam exhaust pipe for secondary heat utilization.

[0036] (5) When the battery enters the left end of the oiling mechanism, several sets of oiling rollers rotate clockwise in sync, which causes the battery to roll to the right. During the rolling process, the battery comes into full contact with the brush rod and is evenly coated with anti-rust oil. The brush rod will come into contact with the anti-rust oil in the oil supply tank during the rotation process, ensuring that there is enough oil on the brush rod. The oiling mechanism and the drying roller mechanism are connected by a chain structure and operate synchronously to form a close linkage. The oiling effect is better when the battery is coated immediately after drying. They also share a power source, which improves resource utilization and reduces the complexity of the process and the complexity of the equipment structure. Attached Figure Description

Detailed Implementation

[0049] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0050] Example 1:

[0051] like Figure 1-6 As shown, this embodiment provides a cylindrical battery manufacturing apparatus and manufacturing process, including a cleaning device 1. The left end of the cleaning device 1 is provided with a discharge channel 3, which is slightly inclined to facilitate horizontal discharge. Several sets of cylindrical batteries 4 are arranged on the discharge channel 3, and an intermittent feeder 7 is provided on the right side of the discharge channel 3.

[0052] Specifically, the intermittent feeder 7 includes a rotating rod 71, a side support 72, a rotary motor unit 73, a feeding plate 74, a receiving surface 75, and a stop surface 76, as shown below. Figure 3 As shown.

[0053] In this embodiment, the rotating rod 71 is horizontally arranged, with one end connected to the bearing seat and the side support 72, and the other end connected to the rotating motor group 73 coupling. Several sets of material feeding plates 74 are equidistantly sleeved on the rotating rod 71.

[0054] In this embodiment, the feeding plate 74 includes a back panel 76 and an inner storage surface 75. The shape of the storage surface 75 is such that only a single battery can enter. The rotating rod 71 drives the feeding plate 74 to rotate 90 degrees counterclockwise and then 90 degrees clockwise (the rotation pattern is preset by the angle motor group 73), and so on.

[0055] Furthermore, a washing chute 10 is inclinedly provided on the right side of the intermittent feeder 7, such as... Figure 2 As shown.

[0056] Specifically, the rinsing chute 10 is slightly inclined and includes a top plane 11 and a bottom plane. The top plane 11 connects to the cylindrical battery 4 exiting from the intermittent feeder 7, and the bottom plane is provided with a water inlet screen 12 for receiving wastewater from the rinsing chute 10. A wastewater tank is provided at the bottom of the water inlet screen 12 for collecting wastewater. Figure 4 As shown.

[0057] Furthermore, a battery rolling structure 8 is provided at the end of the bottom plane.

[0058] Specifically, the battery rolling structure 8 includes a large rubber roller 80, a first shaft 81, a large sprocket 82, a large gear 83, a small rubber roller 84, a second shaft 85, a small sprocket 86, a first chain 87, and a push plate 88, as shown below. Figure 6As shown.

[0059] In this embodiment, the first shaft portions 81 at both ends of the large rubber wheel 80 are fixed by bearing seats, and a large sprocket 82 and a large gear 83 are sequentially sleeved on the front first shaft portion 81. The second shaft portions 85 at both ends of the small rubber wheel 84 are fixed by bearing seats. The small rubber wheel 84 is located at the bottom chamfer of the rinsing slide 10. Both the large rubber wheel 80 and the small rubber wheel 84 are made of waterproof rubber, which is waterproof on the one hand and causes little damage to the battery surface on the other.

[0060] In this embodiment, a small sprocket 86 is sleeved on the second shaft part 85 at the front end. The large sprocket 82 and the small sprocket 86 are connected by a first chain 87 for clockwise transmission. A set of push plates 88 acting on the cylindrical battery 4 are installed on the surface of the large rubber wheel 80. The push plates 88 are used to hold the cylindrical battery 4 and move with the wheel. The area between the large rubber wheel 80 and the small rubber wheel 84 allows the cylindrical battery 4 to roll irregularly, so as to make the cylindrical battery 4 continuously turn over.

[0061] Among them, a small gear 42 is meshed at the upper end of the large gear 83. The small gear 42 is mounted on the output shaft of the constant speed motor 41. The constant speed motor 41 is located inside the motor base 40, and the motor base 40 is riveted to the front end face of the cleaning device 1. Figure 2 As shown.

[0062] Furthermore, a cleaning seat 15 is fixedly installed directly above the battery rolling structure 8 and the upper end of the cleaning device 1. Several sets of nozzles 16 are equidistantly arranged at the bottom of the cleaning seat 15, and the nozzles 16 act on the cylindrical battery 4.

[0063] In this embodiment, a clean water tank 13 and a corrosion inhibitor tank 14 are symmetrically arranged on the upper part of the cleaning seat 15. Both are connected to the internal pipes of the cleaning seat 15 and supply liquid sequentially. The supply is controlled by two control valves, such as... Figure 2 As shown.

[0064] In this embodiment, a rinsing pipe 18 is provided above the rinsing chute 10. The rinsing pipe 18 is installed on the top of the cleaning device 1 via a pipe bracket 19, serving as a fixed connection. Several sets of rinsing holes are equidistantly provided at the bottom of the rinsing pipe 18, such as... Figure 2 As shown.

[0065] In this embodiment, the upper middle part of the rinsing pipe 18 is connected to the liquid inlet pipe 17, which extends downward and connects to the bottom of the return tank. A water pump is installed therein, and the return tank is connected to the return pipe below the battery rolling structure 8 to achieve the purpose of return.

[0066] Furthermore, the left end of the cleaning device 1 is connected to the cylindrical battery assembly line 43 to continuously supply batteries.

[0067] In this embodiment, complete batteries with caps assembled at the cylindrical battery assembly line 43 are continuously transported by belt to the discharge channel 3 and arranged there. They are blocked by the baffle 76 of the feeding plate 74. By starting the angle motor 73, the rotating rod 71 drives the feeding plate 74 to rotate 90 degrees counterclockwise, allowing a group of batteries to enter the receiving surface 75 of the feeding plate 74 and be temporarily stored. Then, the rotating rod 71 drives the feeding plate 74 to rotate 90 degrees clockwise, and the batteries in the receiving surface 75 roll downwards and enter the top plane 11 of the rinsing slide 10. The intermittent feeder 7 operates in this cycle, allowing each group of batteries to be discharged individually. Afterwards, the batteries roll downwards from the rinsing slide 10. During the rolling process, the liquid inlet pipe 17 draws back the mixed liquid (a mixture of clean water and corrosion inhibitor) from the liquid tank and enters the rinsing pipe 18, dripping down from several sets of rinsing holes, allowing the passing batteries to undergo the initial rinsing. After removing oil and dust from the battery, the dripping liquid also cleans the rinsing slide 10. The battery then falls into the battery rolling structure 8 (the area between the large rubber wheel 80 and the small rubber wheel 84). By starting the uniform speed motor 41, the large rubber wheel 80 is slowly rotated clockwise through the reduction of large and small gears. Then, the small rubber wheel 84 is rotated synchronously in the same direction through the chain structure. This causes the battery, which has frictional contact with the rubber surface, to rotate irregularly between the two (the frictional force at both points causes the battery to rotate counterclockwise). During the rotation, several sets of nozzles 16 in the cleaning seat 15 spray corrosion inhibitor onto the battery first, and then spray clean water for a second cleaning. The cleaning mixture flows into the return tank through the return pipe for later use. When the large rubber wheel 80 rotates one revolution, the push plate 88 pushes the battery out from the top of the large rubber wheel 80 and into the drying oven for drying.

[0068] Example 2:

[0069] Based on Example 1, existing batteries are generally dried using hot air, which is continuously supplied and non-recyclable, resulting in low thermal efficiency. Furthermore, a separate oiling device is required after drying, complicating the process. To address these technical problems, we designed the following solution: Figure 7-11 As shown.

[0070] Specifically, the drying device 2 is connected to the cleaning device 1 via the first belt conveyor 20, and a drying roller mechanism is installed inside the drying device 2 on the left side.

[0071] Furthermore, the drying roller mechanism consists of several groups of drying rollers 9 arranged horizontally at equal intervals, such as... Figure 9 As shown.

[0072] Specifically, the drying roller 9 includes a hollow roller body 91, a hollow shaft tube 92, a water-absorbing fabric layer 93, a first bearing 94, a second bearing 95, and a first sprocket 96, as shown below. Figure 10 As shown.

[0073] In this embodiment, hollow roller body 91 is welded to both ends with hollow shaft tubes 92, and the surface of hollow roller body 91 is covered with absorbent fabric layer 93. The layer is thick and has a buffering effect to protect the battery. The two sets of hollow shaft tubes 92 are fixed to the inner wall of drying device 2 in sequence through bearing 1 94 and bearing 2 95.

[0074] In this embodiment, two sets of No. 1 sprockets 96 are sleeved on the front hollow shaft tube 92, and the left and right adjacent No. 1 sprockets 96 are connected and driven by a second chain.

[0075] Furthermore, outer protective seats 21 are installed at both the front and rear of the drying device 2. Several sets of ventilated bearing seats 22 are fixedly installed on the inner side of the outer protective seats 21 (insulation layers can be installed on the outer surfaces of both the ventilated bearing seats 22 and the hollow shaft tube 92). The ventilated bearing seats 22 are sequentially connected to the extended hollow shaft tube 92. The front end of the ventilated bearing seat 22 is an inner bearing, and the rear end is a cavity. Figure 9 As shown.

[0076] Furthermore, the front end face of the first set of ventilation bearing seats 22 on the left is connected to the high-temperature steam inlet pipe 24, and the rear end face of the first set of ventilation bearing seats 22 on the right is connected to the high-temperature steam outlet pipe 25. Connecting pipes 23 are arranged between adjacent ventilation bearing seats 22 in a head-to-tail connection order. (See details...) Figure 9 The connection order shown in the image.

[0077] Furthermore, an oiling mechanism is installed inside the drying device 2, and a second belt conveyor 26 is installed between the drying roller mechanism and the oiling mechanism. The drying roller mechanism, the second belt conveyor 26 and the oiling mechanism decrease in height in sequence. Correction roller devices can be installed on both the first belt conveyor 20 and the second belt conveyor 26. The battery is restored to a horizontal state by intermittent blocking of the correction roller.

[0078] Specifically, the oiling mechanism consists of several groups of oiling rollers 27 arranged horizontally at equal intervals. Each oiling roller 27 includes a brush rod 30, a third shaft 31, a third bearing 32, a fourth bearing 33, and a second sprocket 34. Figure 11 As shown.

[0079] In this embodiment, both ends of the coating rod 30 are welded with a third shaft 31. The two sets of third shafts 31 are fixed to the inner wall of the drying device 2 by the third bearing 32 and the fourth bearing 33 in sequence. Two sets of second sprockets 34 are sleeved on the front end of the third shaft 31.

[0080] In this embodiment, the bottom of the oiling mechanism is provided with an oil supply groove 35. The edge of the oil supply groove 35 is provided with a slot 36 for fixing the No. 3 bearing 32 and the No. 4 bearing 33, which serves to connect and fix them. The lower end face of the oiling roller 27 contacts the anti-rust oil in the oil supply groove 35, but not directly. It is generally supplied through a sponge roller.

[0081] The two adjacent sprockets 34 on the left and right are connected by a third chain, and the sprocket 96 on the rightmost drying roller 9 and the sprocket 34 on the leftmost oiling roller 27 are connected by a fourth chain. Figure 8 As shown.

[0082] Furthermore, a support base 44 is provided at the left end of the drying device 2, and the support base 44 is located at the bottom of the washing device 1, such as... Figure 7 As shown.

[0083] Furthermore, the second sprocket 34 on the rightmost oiling roller 27 is connected to the inner sprocket structure of the high-power motor unit 45.

[0084] Furthermore, the right end of the drying device 2 is connected to the heat shrink fitting production line 46, and the high-temperature steam exhaust pipe 25 is introduced into the heat shrink fitting production line 46 to serve as a heat source during heat shrinking.

[0085] In this embodiment, after cleaning, the batteries are transferred from the battery rolling structure 8 to the first belt conveyor 20, transported from left to right, and enter the left end of the drying roller mechanism. Several sets of drying rollers 9 rotate synchronously clockwise (driven by the sprocket structure), causing the batteries to tumble. During the tumbling process, the batteries come into full contact with the absorbent cloth layer 93 of the drying rollers 9, thus absorbing the moisture and achieving a drying effect. At the same time, high-temperature steam passes through the hollow roller body 91 of each set of drying rollers 9 at regular intervals, which can heat the entire drying roller 9 and dry the damp absorbent cloth. After the material layer 93 is dried, the battery enters the second belt conveyor 26 and moves to the right with the second belt conveyor 26. After the battery is corrected to be horizontal, it enters the left end of the oiling mechanism. Several sets of oiling rollers 27 rotate clockwise synchronously, which causes the battery to tumble to the right. During the tumbling process, the battery comes into full contact with the brush 30 and is evenly coated with anti-rust oil. The brush 30 will come into contact with the anti-rust oil in the oil supply tank 35 during the rotation process, ensuring that there is enough oil on the brush 30. After oiling, the battery is transferred to the heat shrink sleeve production line 46 for sleeve assembly.

6. A cylindrical battery manufacturing process, applied to the cylindrical battery manufacturing apparatus of claim 5, characterized in that, The steps include the following: S1: Complete batteries with caps assembled at the cylindrical battery assembly line (43) will be continuously transported by belt to the discharge channel (3) and arranged. They are blocked by the baffle (76) of the feeding plate (74). By starting the corner motor (73), the rotating rod (71) drives the feeding plate (74) to rotate 90 degrees counterclockwise, allowing a group of batteries to enter the receiving surface (75) of the feeding plate (74) and be temporarily stored. Then the rotating rod (71) drives the feeding plate (74) to rotate 90 degrees clockwise again, and the batteries in the receiving surface (75) roll downwards and enter the top plane (11) of the rinsing slide (10). The intermittent feeder (7) operates in this cycle, allowing each group of batteries to be discharged individually. S2: Then the battery rolls down the rinsing slide (10). During the rolling process, the liquid inlet pipe (17) is used to draw back the mixed liquid in the liquid tank and enter the rinsing pipe (18). The liquid drips down from several sets of rinsing holes, allowing the battery to undergo the first rinse, removing the oil stains and dust on the battery. The dripping liquid will also clean the rinsing slide (10). S3: The battery then falls into the battery rolling structure (8). By starting the uniform speed motor (41), the large rubber wheel (80) is driven to rotate slowly clockwise through the large and small gears. Then, the small rubber wheel (84) is driven to rotate synchronously and in the same direction through the chain structure, so that the battery that has frictional contact with the rubber surface rotates irregularly between the two. During the rotation, the battery is sprayed with corrosion inhibitor by several sets of nozzles (16) in the cleaning seat (15) first, and then with clean water, to perform a second cleaning of the whole body. The cleaning mixture flows into the return tank through the return pipe for later use. When the large rubber wheel (80) rotates once, the push plate (88) pushes the battery out from the top of the large rubber wheel (80). S4: The battery after being cleaned from the battery rolling structure (8) is transferred to the first belt conveyor (20) and transported from left to right into the left end of the drying roller mechanism. Several sets of drying rollers (9) rotate clockwise in sync, thereby causing the battery to roll to the right. During the rolling process, the battery comes into full contact with the absorbent cloth layer (93) of the drying roller (9), thereby absorbing the moisture and achieving the drying effect. At the same time, high-temperature steam passes through the hollow roller body (91) of each set of drying rollers (9) at regular intervals, which can heat the entire drying roller (9) and dry the damp absorbent cloth layer (93). S5: After drying, the battery enters the second belt conveyor (26), moves to the right with the second belt conveyor (26), and after correcting the horizontal direction of the battery, enters the left end of the oiling mechanism. The oiling mechanism and the drying roller mechanism are connected by a chain structure and operate synchronously. Several sets of oiling rollers (27) rotate clockwise synchronously, thereby causing the battery to roll to the right. During the rolling process, the battery fully contacts the brush rod (30) and is evenly coated with anti-rust oil. The brush rod (30) will contact the anti-rust oil in the oil supply tank (35) during the rotation process, ensuring that there is enough oil on the brush rod (30). After oiling, the battery is transferred to the heat shrink sleeve production line (46) for sleeve assembly.
