Description

Technical Field

[0001] The utility model relates to the technical field of production equipment, in particular to a conveying device and a battery cleaning and oiling system. Background Art

[0002] The conveying device usually includes a motor, a transmission mechanism and a conveying member. The conveying member is usually a conveying chain or a conveyor belt. The motor is connected to the conveying member through the transmission mechanism to drive the conveying member to convey materials in a specific direction. When the material is clamped or placed on the conveying member in the next process, the conveying member needs to stop conveying to prevent the relative movement between the conveying member and the material and friction damage to the material. A sensor is set at a specific position. When the sensor senses a signal, the motor stops to stop the conveying member from conveying. In this way, the motor starts and stops once every time the material on the conveying member is clamped. Frequent starts and stops of the motor during the entire production process shorten the life of the motor. Moreover, once the sensor is damaged, the conveying member cannot start and stop according to the process requirements, resulting in a shutdown failure.

[0003] For example, in the battery cleaning and oiling system, there are cleaning chains and oiling chains, each of which is driven and controlled by a motor. After the battery is cleaned and dried on the cleaning chain, it needs to be clamped to the oiling chain by a manipulator. When clamping and releasing the battery, the motor needs to be started and stopped to control the cleaning chain and the oiling chain to stop. In the battery cleaning and oiling process, the frequent start and stop of the motor shortens the motor life and the high motor failure rate, resulting in a long downtime for maintenance of the production system, which is not conducive to improving the production rhythm.

[0004] Therefore, there is an urgent need for a conveying device and a battery cleaning and oiling system to solve the above-mentioned problems existing in the prior art. Utility Model Content

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0081] like Figure 1 and Figure 2As shown, 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.

[0082] Among them, combined Figure 3 The first conveying unit 1 includes a first intermittent motion mechanism 11 and a first conveying member 12 for conveying materials, and the first intermittent motion mechanism 11 is in 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 for conveying materials, and the second intermittent motion mechanism 21 is in transmission connection with the second conveying member 22.

[0084] The transfer unit 3 is located between the first conveying unit 1 and the second conveying unit 2, and the transfer unit 3 includes a third intermittent motion mechanism 31 and a clamping mechanism 32. The third intermittent motion mechanism 31 is transmission-connected with the clamping mechanism 32, and is used to drive the clamping mechanism 32 to transfer the material on the first conveying member 12 to the second conveying member 22. The total drive unit 4 is transmission-connected with 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 to drive the first conveying member 12, the second conveying member 22 and the clamping mechanism 32 to intermittently move. 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 materials.

[0085] In the conveying device provided in this embodiment, the first conveying unit 1 and the second conveying unit 2 are both used to convey materials, and the transfer unit 3 is used 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 total driving 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 total rotating unit, 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.

In the conveying device, the cooperation of the first intermittent motion mechanism 11, the second intermittent motion mechanism 21 and the third intermittent motion mechanism 31 can avoid frequent start and stop of the total drive unit 4, extend the service life of the total drive unit 4, reduce the failure rate of the total drive unit 4, reduce the system downtime maintenance time, and improve reliability and production cycle. Moreover, the first intermittent motion mechanism 11, the second intermittent motion mechanism 21 and the third intermittent motion mechanism 31 can be driven by only one total drive unit 4, which can reduce costs.

[0086] 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.

[0087] Furthermore, 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.

[0088] Exemplarily, the total driving 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.

[0089] For the convenience of description, this embodiment introduces the X direction, the Y direction and the Z direction for description, wherein the first conveying member 12 and the second conveying member 22 both convey materials along the X direction, and the first conveying member 12 and the second conveying member 22 are spaced apart along the X direction.

[0096] 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.

[0097] See also Figure 3 and Figure 7The third intermittent motion mechanism 31 is located above the main transmission shaft 51, so as to drive the clamping mechanism 32 to clamp and transfer the materials on the first conveying member 12. The conveying device also includes a fixing frame 61 for mounting the third intermittent motion mechanism 31, and the fixing frame 61 is arranged between the first conveying unit 1 and the second conveying unit 2.

The third driven wheel 542 and the fourth driving wheel 544 are coaxially connected to the two ends of the first transmission shaft 62, respectively. Therefore, when the third driven wheel 542 rotates, the fourth driving wheel 544 is driven to rotate through the first transmission shaft 62, and the fourth driving wheel 544 drives the fourth driven wheel 545 to rotate through the fourth transmission belt 546.

In order to realize that the first intermittent motion mechanism 11 drives the first conveying member 12 to convey, a second transmission shaft 13 is arranged 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, that is, extends 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 a belt transmission mechanism; the sixth driving wheel 18, the sixth driven wheel 19 and the sixth transmission belt 110 constitute another belt transmission mechanism.

[0103] Among them, see 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 meshed with the first conveying member 12; the sixth driving wheel 18 is coaxially connected to one 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; the sixth transmission belt 110 is sleeved on the sixth driving wheel 18 and the sixth driven wheel 19.

[0104] When the first intermittent motion mechanism 11 is driven by the first transmission mechanism 52 to operate, it drives the fifth driving wheel 14 to rotate intermittently, the fifth driving wheel 14 drives the fifth driven wheel 15 to rotate through the fifth transmission belt 16, when the fifth driven wheel 15 rotates, it drives the sixth driving wheel 18 to rotate intermittently through the second transmission shaft 13, the sixth driving wheel 18 then drives the sixth driven wheel 19 to rotate through the sixth transmission belt 110 under the drive of the second transmission shaft 13, the sixth driven wheel 19 then drives the first driving sprocket 17 to rotate intermittently, and the first driving sprocket 17 drives the first conveying member 12 to move intermittently. 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.

[0105] In some other embodiments, if the output end of the first intermittent motion mechanism 11 faces the first conveying member 12 , only one set of belt transmission mechanisms may be provided to connect between the output end of the first intermittent motion mechanism 11 and the first driving sprocket 17 .

[0106] Alternatively, see Figure 4 , Figure 5 and Figure 6The 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 on 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.

[0107] When the second intermittent motion mechanism 21 is driven by the second transmission mechanism 53 to operate, it drives the seventh driving wheel 24 to rotate intermittently, the seventh driving wheel 24 drives the seventh driven wheel 25 to rotate through the seventh transmission belt 26, and the seventh driven wheel 25 drives the second conveying member 22 to start and stop intermittently through 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.

[0108] In other embodiments, if the output end of the second intermittent motion mechanism 21 faces 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.

[0109] Exemplarily, 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 transmission stability.

[0110] In this embodiment, both the first intermittent motion mechanism 11 and the second intermittent motion mechanism 21 are cam dividers that only realize intermittent rotary motion.

[0111] See also Figure 7 The conveying device also includes a transfer workbench 63 located between the first conveying member 12 and the second conveying member 22. The clamping mechanism 32 first clamps and transfers the material on the first conveying member 12 to the transfer workbench 63, and then clamps and transfers the material on the transfer workbench 63 to the second conveying member 22.

[0112] See also Figure 8 The transfer unit 3 further includes a mounting plate 33, which is connected to the output end of the third intermittent motion mechanism 31. The mounting plate 33 can be lifted and rotated under the drive of the third intermittent motion mechanism 31. The clamping mechanism 32 is mounted on the mounting plate 33. When the mounting plate 33 is lifted and rotated, the mounting plate 33 drives the clamping mechanism 32 to be lifted and rotated.

[0113] In this embodiment, the third intermittent motion mechanism 31 is a lifting and swinging cam divider, which is provided with a connecting rod mechanism inside, and can realize both intermittent lifting and intermittent rotation. The lifting and swinging cam divider is an existing mature technology and will not be described here.

[0114] 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 31 to rotate around the Z direction.

[0115] See also Figure 8 and Fig. 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 used 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 move relatively close to clamp the material in between.

[0116] It should be noted that 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 to each other, one end of which is connected to the housing or output end of the linear drive mechanism 3211, and the other end is used to clamp the material.

[0117] Exemplarily, the linear drive mechanism 3211 may be a linear motion mechanism such as a pneumatic cylinder, an oil cylinder, an electric cylinder, etc., but is not limited to the above mechanisms.

[0118] 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, and the driving direction of the linear drive mechanism 3211 of the first clamping assembly 321 is perpendicular to the driving direction of the linear drive mechanism 3211 of the second clamping assembly 322. The plurality of first clamping assemblies 321 are used to transfer the materials on the first conveying member 12 to the transfer workbench 63 under the drive of the third intermittent motion mechanism 31, and the plurality of second clamping assemblies 322 are used to transfer the materials on the transfer workbench 63 to the second conveying member 22 under the drive of the third intermittent motion mechanism 31.

[0119] The first conveying member 12, the transfer worktable 63 and the second conveying member 22 are arranged along the X direction. After the plurality of first clamping components 321 clamp the plurality of materials, they rotate to the top of the transfer worktable 63 under the drive of the third intermittent motion mechanism 31, and place the clamped materials on the worktable, and then rotate in the opposite direction back to the top of the first conveying member 12 to continue clamping the materials. When the first clamping components 321 clamp the materials on the first conveying member 12, the plurality of second clamping components 322 clamp the plurality of materials placed on the transfer worktable 63, and rotate to the top of the second conveying member 22 under the drive of the third intermittent motion mechanism 31, and place the clamped materials on the second conveying member 22. In this way, the clamping and transportation efficiency of the materials can be improved by the plurality of first clamping components 321 and the plurality of second clamping components 322.

[0120] Taking cylindrical batteries as an example, the axis of the battery 300 transported on the first conveyor 12 and the second conveyor 22 is along the Y direction, and multiple cylindrical battery grooves are provided on the transfer workbench 63 for clamping cylindrical batteries, and the axis of the cylindrical battery grooves extends along the X direction. After the multiple first clamping components 321 clamp the cylindrical batteries, they rotate 90 degrees to reach the transfer workbench 63, and place the multiple cylindrical batteries in the cylindrical battery grooves of the transfer workbench 63. After the multiple second clamping components 322 clamp the multiple cylindrical batteries on the transfer workbench 63, they rotate 90 degrees to place the multiple cylindrical batteries on the second conveyor 22.

[0121] See also Figure 3 , Figure 6 as well as Figure 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 to each other one by one, so that the cylindrical batteries on the two first conveying members 12 can be transferred, and the conveying efficiency is improved.

[0122] It should be noted that a transmission wheel is coaxially connected to the transfer input shaft 311 of the third intermittent motion mechanism 31 of one of the 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.

[0123] Optionally, the rotation directions of the two transfer units 3 are mirror-symmetrical. Specifically, when the battery 300 on the first conveying member 12 is clamped and transferred to the transfer workbench 63, one of the first clamping components 321 of the two transfer units 3 rotates clockwise and the other rotates counterclockwise. Such an arrangement makes the structure more compact and reasonable, and occupies less space during movement.

[0124] See also Figure 1 and Figure 2 , this embodiment also provides a battery cleaning and oiling system, including a cleaning device 100, an oiling device 200 and the conveying device as described above. The above-mentioned material is a battery 300, and the battery 300 can be a cylindrical battery or a square battery, etc. The first conveying unit 1 includes a first frame 120, and the first conveying member 12 and the cleaning device 100 are both installed on the first frame 120, and the cleaning device 100 is used to clean the battery 300 on the first conveying member 12; the second conveying unit 2 includes a second frame 27, and the second conveying member 22 and the oiling device 200 are both installed on the second frame 27, and the oiling device 200 is used to oil the battery 300 on the second conveying member 22. Furthermore, a drying device is also provided on the first frame 120, and the drying device is located downstream of the cleaning device 100, and is used to dry the battery 300 after the battery 300 is cleaned.

[0125] The battery cleaning and oiling system with the above-mentioned conveying device 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.

[0126] The working process of the battery cleaning and oiling system provided in this embodiment is roughly as follows:

[0127] The loading robot places the battery 300 on the first conveyor 12. The battery 300 is cleaned when it passes 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 from conveying. 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.

[0128] 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 the original position (i.e., the first clamping assembly 321 rotates back to the top of the first conveying member 12, and the second clamping assembly 322 rotates back to the top of the transfer workbench 63), and the first conveying member 12 continues to operate under the drive of the first intermittent motion mechanism 11, and stops when the transfer unit 3 clamps the battery 300 on the first conveying member 12 next time. During this period, the first intermittent motion mechanism 11 completes the start and stop control of the first conveying member 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 conveying member 12, and multiple second clamping assemblies 322 clamp multiple batteries 300 on the transfer workbench 63. After the clamping is completed, 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, so as to convey the battery 300 to the position of the oil coating device 200 for oil coating.

[0129] Each mechanism performs actions according to the above steps to complete the cleaning and oiling process of the battery 300.
