Description

Conveying device and battery cleaning and oiling system

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on May 23, 2024, with application number 202421140848.X. The entire contents of the above application are incorporated by reference into this application.

[0002] Technical Field

[0003] The present application relates to the technical field of production equipment, for example, to a conveying device and a battery cleaning and oiling system.

[0004] Background Art

[0005] A conveyor typically consists of a motor, a transmission mechanism, and a conveyor element. The conveyor element is typically a chain or belt. The motor is connected to the conveyor element through the transmission mechanism, driving the conveyor element to transport materials in a specific direction. When materials are being clamped or placed on a conveyor element for the next process, the conveyor element must stop to prevent relative motion between the conveyor element and the material, which could cause friction and damage. This is typically accomplished by placing a sensor at a specific location. When the sensor detects a signal, the motor stops, halting the conveyor element.

[0006] Technical issues

[0007] Because the motor starts and stops every time it clamps material on the conveyor, frequent starts and stops throughout the production process shorten the motor's lifespan. Furthermore, if the sensor is damaged, the conveyor will not start and stop according to the process requirements, causing downtime.

[0008] For example, a battery cleaning and oiling system includes a cleaning chain and an oiling chain, each driven by a motor. After the battery is cleaned and dried on the cleaning chain, it is clamped to the oiling chain by a robotic arm. The motors are started and stopped to control the cleaning and oiling chains during the battery cleaning and oiling process. Frequent motor starts and stops during the battery cleaning and oiling process shorten the motor lifespan, increase the motor failure rate, and result in long downtime for maintenance, hindering production cycle times.

[0081] Modes for Carrying Out the Invention

[0082] As shown in FIG. 1 and FIG. 2 , this embodiment provides a conveying device, including a first conveying unit 1 , a second conveying unit 2 , a transfer unit 3 , a main driving unit 4 and a main transmission unit 5 .

[0083] 3 , the first conveying unit 1 includes a first intermittent motion mechanism 11 and a first conveying member 12 configured to convey materials, and the first intermittent motion mechanism 11 is in a transmission connection with the first conveying member 12. The second conveying unit 2 includes a second intermittent motion mechanism 21 and a second conveying member 22 configured to convey materials, and the second intermittent motion mechanism 21 is in a transmission connection with the second conveying member 22.

[0084] For example, the first conveyor member 12 and / or the second conveyor member 22 are conveyor chains. Alternatively, the first conveyor member 12 and / or the second conveyor member 22 are synchronous belts, as long as they can convey materials. The conveyed materials can be batteries 300, other workpieces, products, etc., and the materials are not specifically limited here.

[0085] The transfer unit 3 is located between the first conveying unit 1 and the second conveying unit 2 and includes a third intermittent motion mechanism 31 and a clamping mechanism 32. The third intermittent motion mechanism 31 is transmission-connected to the clamping mechanism 32 and is configured to drive the clamping mechanism 32 to transfer material from the first conveying member 12 to the second conveying member 22. The main drive unit 4 is transmission-connected to the first intermittent motion mechanism 11, the second intermittent motion mechanism 21, and the third intermittent motion mechanism 31 via the main transmission unit 5 to drive the first conveying member 12, the second conveying member 22, and the clamping mechanism 32 to intermittent motion, respectively. That is, the first conveying member 12 starts and stops regularly under the drive of the first intermittent motion mechanism 11, the second conveying member 22 starts and stops regularly under the drive of the second intermittent motion mechanism 21, and the clamping mechanism 32 moves regularly under the drive of the third intermittent motion mechanism 31 to transfer material.

[0086] In the conveying device provided in this embodiment, the first conveying unit 1 and the second conveying unit 2 are both configured to convey materials, and the transfer unit 3 is configured to transfer the materials conveyed on the first conveying member 12 of the first conveying unit 1 to the second conveying member 22 of the second conveying unit 2. The main drive unit 4 is connected to the first intermittent motion mechanism 11, the second intermittent motion mechanism 21, and the third intermittent motion mechanism 31 through the main transmission unit 5, so that the first intermittent motion mechanism 11 controls the intermittent motion of the first conveying member 12, the second intermittent motion mechanism 21 controls the intermittent motion of the second conveying member 22, and the third intermittent motion mechanism 31 controls the intermittent motion of the clamping mechanism 32. By controlling the timing of the first intermittent motion mechanism 11, the second intermittent motion mechanism 21, and the third intermittent motion mechanism 31, the start and stop timing of the first conveying member 12, the second conveying member 22, and the clamping mechanism 32 can be controlled, so that the clamping mechanism 32 can clamp the materials on the stopped first conveying member 12 and transfer the materials to the stopped second conveying member 22. No sensor is required, thus avoiding the situation where the entire machine stops due to sensor failure.

[0087] In this conveying device, the coordination of the first intermittent motion mechanism 11, the second intermittent motion mechanism 21, and the third intermittent motion mechanism 31 can prevent frequent starts and stops of the main drive unit 4, thereby extending the service life of the main drive unit 4, reducing the failure rate of the main drive unit 4, shortening the system downtime for maintenance, and improving reliability and production cycle time. Moreover, a single main drive unit 4 can drive the first intermittent motion mechanism 11, the second intermittent motion mechanism 21, and the third intermittent motion mechanism 31, thereby reducing costs.

[0088] Exemplarily, the first intermittent motion mechanism 11 , the second intermittent motion mechanism 21 and the third intermittent motion mechanism 31 are all cam dividers, which can realize intermittent motion, are accurate and reliable, and are easy to control.

[0089] In some embodiments, the conveying device also includes a timing control mechanism, and the first intermittent motion mechanism 11, the second intermittent motion mechanism 21 and the third intermittent motion mechanism 31 respectively use different timing control mechanisms to complete the movement uninterruptedly, that is, the start and stop rhythm of the first intermittent motion mechanism 11, the second intermittent motion mechanism 21 and the third intermittent motion mechanism 31 can be controlled by the timing control mechanism, so that the start and stop rhythm of the first intermittent motion mechanism 11, the second intermittent motion mechanism 21 and the third intermittent motion mechanism 31 are matched, so that the total drive unit 4 does not need to start and stop frequently.

[0090] Exemplarily, the total drive unit 4 is a rotating motor, which is connected to the first intermittent motion mechanism 11, the second intermittent motion mechanism 21 and the third intermittent motion mechanism 31 through the total transmission unit 5. The rotating motor does not need to be started and stopped frequently, which can extend its service life.

[0091] For ease of explanation, this embodiment introduces the X-, Y-, and Z-directions. The first conveyor member 12 and the second conveyor member 22 both convey materials along the X-direction, and the first conveyor member 12 and the second conveyor member 22 are spaced apart along the X-direction. The Y-direction is the width of the first conveyor member 12 and the second conveyor member 22, and the Z-direction is the vertical direction. The X-, Y-, and Z-directions are perpendicular to each other.

[0092] In some embodiments, as shown in Figures 1, 2, 3, 4, and 5, the main transmission unit 5 includes a main transmission shaft 51, a first transmission mechanism 52, a second transmission mechanism 53, and a third transmission mechanism 54. The main transmission shaft 51 is connected to the output end of the main drive unit 4 and is configured to rotate under the drive of the main drive unit 4. In this embodiment, the main drive unit 4 is a rotating motor, and the main transmission shaft 51 is connected to the output shaft of the rotating motor. The output shaft of the rotating motor can be directly connected to the main transmission shaft 51 or indirectly connected to the main transmission shaft 51 via a speed reducer, a belt drive mechanism, or the like.

[0093] The main transmission shaft 51 is in transmission connection with the first intermittent motion mechanism 11 via a first transmission mechanism 52; the main transmission shaft 51 is in transmission connection with the second intermittent motion mechanism 21 via a second transmission mechanism 53; and the main transmission shaft 51 is in transmission connection with the third intermittent motion mechanism 31 via a third transmission mechanism 54. In the main transmission unit 5, power is transmitted to the first transmission mechanism 52, the second transmission mechanism 53, and the third transmission mechanism 54 via the single main transmission shaft 51, thereby achieving intermittent motion of the first intermittent motion mechanism 11, the second intermittent motion mechanism 21, and the third intermittent motion mechanism 31, respectively.

[0094] In some embodiments, the main transmission shaft 51 may be a single shaft. In other embodiments, the main transmission shaft 51 may include multiple shafts connected together by a coupling.

[0095] Optionally, referring to FIG4 , the first transmission mechanism 52 includes a first driving wheel 521, a first driven wheel 522, and a first transmission belt 523. The first driving wheel 521 is coaxially connected to the main transmission shaft 51, and the first driven wheel 522 is coaxially connected to the input shaft of the first intermittent motion mechanism 11. The first transmission belt 523 is sleeved over the first driving wheel 521 and the first driven wheel 522. The first driving wheel 521 drives the first driven wheel 522 to rotate via the first transmission belt 523. When the main transmission shaft 51 rotates under the drive of the main drive unit 4, the main transmission shaft 51 drives the first driving wheel 521 to rotate. The first driving wheel 521 drives the first driven wheel 522 to rotate via the first transmission belt 523. The first driven wheel 522 then drives the input shaft of the first intermittent motion mechanism 11 to rotate, thereby achieving intermittent motion at the output end of the first intermittent motion mechanism 11.

[0096] Exemplarily, the first driving wheel 521 and the first driven wheel 522 are synchronous pulleys, and the first transmission belt 523 is a synchronous belt, which has high transmission accuracy and high transmission stability.

[0097] 5 and 6 , the second transmission mechanism 53 includes a second driving pulley 531, a second driven pulley 532, and a second transmission belt 533. The second driving pulley 531 is coaxially connected to the main transmission shaft 51, and the second driven pulley 532 is coaxially connected to the input shaft of the second intermittent motion mechanism 21. The second transmission belt 533 is sleeved over the second driving pulley 531 and the second driven pulley 532. The second driving pulley 531 drives the second driven pulley 532 to rotate via the second transmission belt 533. When the main transmission shaft 51 rotates under the drive of the main drive unit 4, the main transmission shaft 51 drives the second driving pulley 531 to rotate. The second driving pulley 531 drives the second driven pulley 532 to rotate via the second transmission belt 533. The second driven pulley 532 then drives the input shaft of the second intermittent motion mechanism 21 to rotate, achieving intermittent motion at the output end of the second intermittent motion mechanism 21.

[0098] Exemplarily, the second driving wheel 531 and the second driven wheel 532 are synchronous pulleys, and the second transmission belt 533 is a synchronous belt, which has high transmission accuracy and high transmission stability.

[0099] As shown in Figures 3 and 7 , the third intermittent motion mechanism 31 is located above the main transmission shaft 51, facilitating the driving of the clamping mechanism 32 to clamp and transfer material on the first conveying member 12. The conveying device also includes a mounting bracket 61 for mounting the third intermittent motion mechanism 31. The mounting bracket 61 is positioned between the first conveying unit 1 and the second conveying unit 2. A first transmission shaft 62 is rotatably mounted on the mounting bracket 61. The third transmission mechanism 54 includes a third driving pulley 541, a third driven pulley 542, a third transmission belt 543, a fourth driving pulley 544, a fourth driven pulley 545, and a fourth transmission belt 546.

[0100] The third driving wheel 541 is coaxially connected to the main transmission shaft 51; the third driven wheel 542 is coaxially connected to the first transmission shaft 62; the third transmission belt 543 is sleeved on the third driving wheel 541 and the third driven wheel 542; the fourth driving wheel 544 is coaxially connected to the first transmission shaft 62; the fourth driven wheel 545 is coaxially connected to the input shaft of the third intermittent motion mechanism 31, and the input shaft of the third intermittent motion mechanism 31 is the transfer input shaft 311 shown in Figure 8; the fourth transmission belt 546 is sleeved on the fourth driving wheel 544 and the fourth driven wheel 545.

[0101] When the main transmission shaft 51 rotates under the drive of the main drive unit 4, the main transmission shaft 51 drives the third driving wheel 541 to rotate. Driven by the main transmission shaft 51, the third driving wheel 541 drives the third driven wheel 542 to rotate via the third transmission belt 543. The third driven wheel 542 and the fourth driving wheel 544 are coaxially connected to the ends of the first transmission shaft 62. Therefore, when the third driven wheel 542 rotates, it drives the fourth driving wheel 544 to rotate via the first transmission shaft 62. The fourth driving wheel 544 drives the fourth driven wheel 545 to rotate via the fourth transmission belt 546. The fourth driven wheel 545 drives the input shaft of the third intermittent motion mechanism 31 to rotate, thereby achieving intermittent motion at the output end of the third intermittent motion mechanism 31.

[0102] The first transmission shaft 62 is located on one side of the third intermittent motion mechanism 31 in the horizontal direction, and the third transmission belt 543 extends obliquely upward to the first transmission shaft 62 of the fixed frame 61, thereby transmitting power from the main transmission shaft 51 to the first transmission shaft 62.

[0103] Illustratively, the third driving wheel 541 , the third driven wheel 542 , the fourth driving wheel 544 , and the fourth driven wheel 545 are all synchronous pulleys; the third transmission belt 543 and the fourth transmission belt 546 are all synchronous belts, which have higher transmission accuracy and transmission stability.

[0104] Optionally, referring to FIG4 , the output end of the first intermittent motion mechanism 11 faces away from the first conveying member 12 . To enable the first intermittent motion mechanism 11 to drive the first conveying member 12 for conveying, a second transmission shaft 13 is provided on the housing of the first intermittent motion mechanism 11 . The second transmission shaft 13 extends from the output end of the first intermittent motion mechanism 11 to the first conveying member 12 , i.e., along the Y direction. The first conveying unit 1 also includes a fifth driving wheel 14 , a fifth driven wheel 15 , a fifth transmission belt 16 , a first driving sprocket 17 , a sixth driving wheel 18 , a sixth driven wheel 19 , and a sixth transmission belt 110 . The fifth driving wheel 14 , the fifth driven wheel 15 , and the fifth transmission belt 16 constitute one belt transmission mechanism; the sixth driving wheel 18 , the sixth driven wheel 19 , and the sixth transmission belt 110 constitute another belt transmission mechanism.

[0105] Referring to Figure 4, the fifth driving wheel 14 is coaxially connected to the output end of the first intermittent motion mechanism 11; the fifth driven wheel 15 is coaxially connected to one end of the second transmission shaft 13; the fifth transmission belt 16 is sleeved on the fifth driving wheel 14 and the fifth driven wheel 15; the first driving sprocket 17 is engaged with the first conveying member 12; the sixth driving wheel 18 is coaxially connected to the end of the second transmission shaft 13 away from the fifth driven wheel 15; the sixth driven wheel 19 is coaxially connected to the first driving sprocket 17; and the sixth transmission belt 110 is sleeved on the sixth driving wheel 18 and the sixth driven wheel 19.

[0106] When the first intermittent motion mechanism 11 is driven by the first transmission mechanism 52, it drives the fifth driving wheel 14 to rotate intermittently. The fifth driving wheel 14 drives the fifth driven wheel 15 to rotate via the fifth transmission belt 16. When the fifth driven wheel 15 rotates, it drives the sixth driving wheel 18 to rotate intermittently via the second transmission shaft 13. The sixth driving wheel 18, in turn, drives the sixth driven wheel 19 to rotate via the sixth transmission belt 110 under the drive of the second transmission shaft 13. The sixth driven wheel 19, in turn, drives the first driving sprocket 17 to rotate intermittently. The first driving sprocket 17 drives the first conveying member 12 to intermittently move. Combined with the timing control mechanism of the first intermittent motion mechanism 11, the start and stop rhythm of the first conveying member 12 is controlled.

[0107] In other embodiments, if the output end of the first intermittent motion mechanism 11 faces the first conveying member 12 , a belt transmission mechanism may be provided to connect between the output end of the first intermittent motion mechanism 11 and the first driving sprocket 17 .

[0108] Optionally, referring to Figures 4, 5, and 6, the output end of the second intermittent motion mechanism 21 faces the second conveying member 22, and the second conveying unit 2 further includes a second driving sprocket 23, a seventh driving wheel 24, a seventh driven wheel 25, and a seventh transmission belt 26. The second driving sprocket 23 is meshed with the second conveying member 22; the seventh driving wheel 24 is coaxially connected to the output end of the second intermittent motion mechanism 21; the seventh driven wheel 25 is coaxially connected to the second driving sprocket 23; and the seventh transmission belt 26 is sleeved around the seventh driving wheel 24 and the seventh driven wheel 25. The seventh driving wheel 24, the seventh driven wheel 25, and the seventh transmission belt 26 constitute a belt transmission mechanism.

[0109] When the second intermittent motion mechanism 21 is driven by the second transmission mechanism 53, it drives the seventh driving wheel 24 to rotate intermittently. The seventh driving wheel 24 drives the seventh driven wheel 25 to rotate via the seventh transmission belt 26. The seventh driven wheel 25 drives the second conveying member 22 to start and stop intermittently via the second driving sprocket 23. Combined with the timing control mechanism of the second intermittent motion mechanism 21, the start and stop rhythm of the second conveying member 22 is controlled.

[0110] In other embodiments, if the output end of the second intermittent motion mechanism 21 is facing away from the first conveying member 12, two sets of belt transmission mechanisms can be set up to connect between the output end of the second intermittent motion mechanism 21 and the second driving sprocket 23, which is similar to the connection method between the first intermittent motion mechanism 11 and the first driving sprocket 17 and will not be described here.

[0111] Illustratively, the fifth driving wheel 14, the fifth driven wheel 15, the sixth driving wheel 18, the sixth driven wheel 19, the seventh driving wheel 24, and the seventh driven wheel 25 are all synchronous pulleys; the fifth transmission belt 16, the sixth transmission belt 110, and the seventh transmission belt 26 are all synchronous belts, with higher transmission accuracy and stability.

[0112] In this embodiment, both the first intermittent motion mechanism 11 and the second intermittent motion mechanism 21 are cam dividers capable of achieving intermittent rotary motion.

[0113] 7 , the conveying device further includes a transfer table 63 located between the first conveying member 12 and the second conveying member 22 . The clamping mechanism 32 clamps and transfers the material on the first conveying member 12 to the transfer table 63 , and then clamps and transfers the material on the transfer table 63 to the second conveying member 22 .

[0114] Referring to Figure 8 , the transfer unit 3 further includes a mounting plate 33 connected to the output end of the third intermittent motion mechanism 31. The mounting plate 33 can be raised and lowered and rotated under the drive of the third intermittent motion mechanism 31. A clamping mechanism 32 is mounted on the mounting plate 33. When the mounting plate 33 is raised and lowered and rotated, the mounting plate 33 drives the clamping mechanism 32 to rise and lower and rotate.

[0115] In this embodiment, the third intermittent motion mechanism 31 is a lifting and swinging cam divider, which is internally provided with a connecting rod mechanism, and can realize both intermittent lifting and intermittent rotation. The lifting and swinging cam divider is a mature technology and will not be described in detail here.

[0116] The third intermittent motion mechanism 31 drives the mounting plate 33 to move up and down along the Z direction, and drives the mounting plate 33 to rotate around the Z direction.

[0117] 8 and 9 , the clamping mechanism 32 includes a plurality of first clamping assemblies 321 and a plurality of second clamping assemblies 322. The plurality of first clamping assemblies 321 constitute a first clamping module, and the plurality of second clamping assemblies 322 constitute a second clamping module. Each first clamping assembly 321 and each second clamping assembly 322 includes a linear drive mechanism 3211, a first clamping member 3212, and a second clamping member 3213. The housing of the linear drive mechanism 3211 is connected to the mounting plate 33, the first clamping member 3212 is connected to the housing of the linear drive mechanism 3211, and the second clamping member 3213 is connected to the output end of the linear drive mechanism 3211. The first clamping member 3212 and the second clamping member 3213 are configured to clamp materials. When the output end of the linear drive mechanism 3211 moves linearly relative to its housing, the first clamping member 3212 and the second clamping member 3213 open relatively to allow the clamped material to enter between the first clamping member 3212 and the second clamping member 3213. Thereafter, the first clamping member 3212 and the second clamping member 3213 approach relatively to clamp the material in the middle.

[0118] Each first clamping assembly 321 clamps one material, and each second clamping assembly 322 clamps one material. The first clamping member 3212 and the second clamping member 3213 are L-shaped plate structures arranged opposite each other. One end of one L-shaped plate structure is connected to the housing of the linear drive mechanism 3211, and the other end is configured to clamp the material. The other end of the L-shaped plate structure is connected to the output end of the linear drive mechanism 3211, and the other end is configured to clamp the material.

[0119] Exemplarily, the linear drive mechanism 3211 may be a linear motion mechanism such as a pneumatic cylinder, an oil cylinder, or an electric cylinder, but is not limited to the above mechanisms.

[0120] The arrangement direction of the plurality of first clamping assemblies 321 is perpendicular to the arrangement direction of the plurality of second clamping assemblies 322. The driving direction of the linear drive mechanism 3211 of the first clamping assemblies 321 is perpendicular to the driving direction of the linear drive mechanism 3211 of the second clamping assemblies 322. The plurality of first clamping assemblies 321 are configured to transfer materials on the first conveying member 12 to the transfer worktable 63 under the drive of the third intermittent motion mechanism 31. The plurality of second clamping assemblies 322 are configured to transfer materials on the transfer worktable 63 to the second conveying member 22 under the drive of the third intermittent motion mechanism 31.

[0121] The first conveyor 12, transfer table 63, and second conveyor 22 are arranged along the X-direction. After clamping multiple materials, the multiple first clamping assemblies 321 are driven by the third intermittent motion mechanism 31 to rotate above the transfer table 63, placing the clamped materials on the transfer table 63. They then rotate in the opposite direction and return to the top of the first conveyor 12 to continue clamping the materials. While the first clamping assemblies 321 are clamping the materials on the first conveyor 12, the multiple second clamping assemblies 322 are clamping the multiple materials placed on the transfer table 63, and driven by the third intermittent motion mechanism 31 to rotate above the second conveyor 22, placing the clamped materials on the second conveyor 22. This arrangement improves the efficiency of material clamping and transfer by using the multiple first clamping assemblies 321 and the multiple second clamping assemblies 322.

[0122] Taking cylindrical batteries as an example, the axis of the battery 300 conveyed on the first conveyor 12 and the second conveyor 22 is along the Y direction. The transfer table 63 is provided with multiple cylindrical battery grooves configured to hold cylindrical batteries, with the axis of the cylindrical battery grooves extending along the X direction. After the multiple first clamping assemblies 321 clamp the cylindrical batteries, they rotate 90 degrees to reach the transfer table 63 and place the multiple cylindrical batteries in the cylindrical battery grooves of the transfer table 63. After the multiple second clamping assemblies 322 clamp the multiple cylindrical batteries on the transfer table 63, they rotate 90 degrees and place the multiple cylindrical batteries on the second conveyor 22.

[0123] 3 , 6 and 7 , two first conveying members 12 and two second conveying members 22 are arranged side by side along the Y direction, and two transfer units 3 are arranged along the Y direction. The first conveying member 12 , the second conveying member 22 and the transfer unit 3 correspond one to one, so that the cylindrical batteries on the two first conveying members 12 can be transferred, and the conveying efficiency is improved.

[0124] A transmission wheel is coaxially connected to the transfer input shaft 311 of the third intermittent motion mechanism 31 of one of the two transfer units 3. The transmission wheel is a synchronous pulley and is located between the fourth driving wheel 544 and the fourth driven wheel 545. The transmission wheel is engaged with the fourth transmission belt 546 and rotates driven by the fourth transmission belt 546 to realize the intermittent motion of the transfer unit 3.

[0125] Optionally, the rotation directions of the two transfer units 3 are mirror-symmetrical. When the battery 300 on the first conveyor 12 is clamped and transferred to the transfer workbench 63, the first clamping assembly 321 of the two transfer units 3 rotates clockwise and counterclockwise, respectively. This arrangement makes the structure more compact and reasonable, and occupies less space during operation.

[0126] 1 and 2 , this embodiment further provides a battery cleaning and oiling system, comprising a cleaning device 100, an oiling device 200, and a conveying device. The material is a battery 300, which can be a cylindrical battery or a square battery, etc. The first conveying unit 1 includes a first frame 120, on which the first conveying member 12 and the cleaning device 100 are both mounted, and the cleaning device 100 is configured to clean the battery 300 on the first conveying member 12; the second conveying unit 2 includes a second frame 27, on which the second conveying member 22 and the oiling device 200 are both mounted, and the oiling device 200 is configured to oil the battery 300 on the second conveying member 22. A drying device is also provided on the first frame 120, which is located downstream of the cleaning device 100 and is configured to dry the battery 300 after it has been cleaned.

[0127] The battery cleaning and oiling system having the conveying device provided in the present application can reduce the number of starts and stops of the total drive unit 4 during the battery 300 cleaning and oiling process, extend the service life of the total drive unit 4, reduce the failure rate of the total drive unit 4, reduce the downtime and maintenance time of the battery cleaning and oiling system, and improve the reliability and production rhythm of the battery 300.

[0128] The working process of the battery cleaning and oiling system provided in this embodiment is roughly as follows:

[0129] The loading robot places the battery 300 on the first conveyor 12. The battery 300 is cleaned while passing through the cleaning device 100 under the conveyance of the first conveyor 12. The cleaned battery 300 continues to be conveyed until it reaches the end of the first conveyor 12. At this time, the first intermittent motion mechanism 11 just stops the first conveyor 12. The third intermittent motion mechanism 31 of the transfer unit 3 drives the clamping mechanism 32 to descend, so that the multiple first clamping components 321 clamp the multiple batteries 300 on the first conveyor 12. At this time, there are no batteries 300 on the transfer workbench 63, and the second clamping component 322 is unloaded. After completing the clamping, the first intermittent motion mechanism 11 drives the clamping mechanism 32 to rotate 90 degrees, and the multiple batteries 300 clamped by the multiple first clamping components 321 are placed on the transfer workbench 63.

[0130] After the first clamping assembly 321 transfers the battery 300 to the transfer workbench 63, the third intermittent motion mechanism 31 drives the clamping mechanism 32 to rise and rotate 90 degrees in the opposite direction to return to its original position (i.e., the first clamping assembly 321 rotates back to the top of the first conveyor 12, and the second clamping assembly 322 rotates back to the top of the transfer workbench 63), and the first conveyor 12 continues to operate under the drive of the first intermittent motion mechanism 11, and stops operating when the transfer unit 3 clamps the battery 300 on the first conveyor 12 next time. During this period, the first intermittent motion mechanism 11 completes the start and stop control of the first conveyor 12 in a prescribed time sequence. Afterwards, under the drive of the third intermittent motion mechanism 31, multiple first clamping assemblies 321 clamp multiple batteries 300 on the first conveyor 12, and multiple second clamping assemblies 322 clamp multiple batteries 300 on the transfer workbench 63. After completing the clamping, the first intermittent motion mechanism 11 drives the clamping mechanism 32 to rotate 90 degrees, and the multiple batteries 300 clamped by the multiple first clamping components 321 are placed on the transfer workbench 63, and the multiple batteries 300 clamped by the multiple second clamping components 322 are placed on the second conveying member 22. Before the battery 300 is placed on the second conveying member 22, the second intermittent motion mechanism 21 controls the second conveying member 22 to stop conveying. After the battery 300 is placed on the second conveying member 22, the second intermittent motion mechanism 21 drives the second conveying member 22 to convey the battery 300 to the oiling device 200 for oiling.

[0131] Each mechanism performs actions according to the above steps to complete the cleaning and oiling process of the battery 300.
