For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0033] The embodiments of the present application are described below with reference to the accompanying drawings. Figure 1 - Figure 4 A transport processing system 100 according to an embodiment of the present application is described.

[0034] The application scenario of the transport processing system 100 according to the embodiment of the present application is not limited, and can be used to process various workpieces, such as power battery cover plates, or to process other components that require high-precision positioning and rapid transmission, such as electronic components, precision mechanical parts, etc.

[0035] The application takes the transportation and processing system 100 for processing power battery cover plate as an example for description, and the following will not be described again.

[0036] As shown in Figure 1 , the transportation and processing system 100 according to the embodiment of the application comprises a conveying line 10, a first conveying mechanism 20, a carrier 30 for mounting workpieces, a work station driving assembly 40 and a power device 50.

[0037] Here, the conveying line 10 is arranged to extend along a first direction.

[0038] The conveying line 10 comprises at least one first conveying section 11. The first conveying section 11 can be flexibly located at an upstream rear section, a middle section or a downstream front section of the conveying line 10.

[0039] In some embodiments as shown in Figure 1 , the first conveying section 11 is the middle section of the conveying line 10.

[0040] The first conveying mechanism 20 is arranged on the first conveying section 11, as shown in Figure 2 , the first conveying mechanism 20 comprises a cam rod 22 arranged along the conveying line 10, and the cam rod 22 is provided with a driving groove 221 extending spirally around the axis of the cam rod 22.

[0041] When the cam rod 22 is driven to rotate by external power, the driving groove 221 will rotate around its axis with the rotation of the cam rod 22. At this time, the components matched with the driving groove 221 can move along the path of the driving groove 221 to realize movement in the length direction of the cam rod 22.

[0042] In combination with Figure 2 , the carrier 30 is assembled on the conveying line 10 to transport workpieces, and the carrier 30 is provided with a cam follower 31 matched with the driving groove 221 when the carrier 30 moves to the first conveying section 11.

[0043] It should be noted that in the transportation and processing system 100, the carrier 30 is assembled on the conveying line 10 to be responsible for transporting workpieces such as power battery covers, parts or other workpieces needing to be transported.

[0044] The role of the carrier 30 is to ensure that the workpieces can move smoothly along the predetermined path. When the carrier 30 moves along the conveying line 10 to the first conveying section 11, the cam follower 31 carried by the carrier 30 will be matched with the driving groove 221 arranged on the cam rod 22.

[0045] Optionally, the cam follower 31 is shaped and sized to fit within the drive slot 221. This ensures that the two can engage. The engagement of the cam follower 31 and the drive slot 221 allows the drive slot 221 to guide the cam follower 31 along its helical path as the cam rod 22 is rotated by an external driving force. The movement of the cam follower 31 in turn causes the carrier 30 and the workpiece thereon to move smoothly along the first direction of the conveyor line 10.

[0046] As the carriers 30 move, they will pass through various tooling stations in sequence. Each tooling station will perform a corresponding processing operation on the workpiece according to a predetermined processing flow.

[0047] This allows the movement of the carriers 30 within the first conveying section 11 to be both continuous and controllable, enabling the carriers 30 to be accurately conveyed to a designated location for processing or other operations while maintaining the stability of the materials on the carriers 30 and reducing errors caused by fluctuations in speed during transmission.

[0048] Optionally, the helix angle and shape of the drive slot 221 can be adjusted as needed. By adjusting the helix angle and shape, the speed and path of the cam follower 31 can be controlled, thereby accurately controlling the conveying speed and position of the workpiece and achieving a higher precision transmission effect.

[0049] The tooling station driving assembly 40 is provided on at least one side of the first conveying section 11 for assembling processing equipment to process the workpiece.

[0050] The tooling station driving assembly 40 can be used to support and drive the assembled processing assembly to perform processing operations on the moving workpiece on the conveyor line 10.

[0051] In some alternative embodiments, there are multiple tooling station driving assemblies 40. The multiple tooling station driving assemblies 40 can be provided on the same side or different sides of the first conveying section 11.

[0052] For example, on a processing line for a power battery cover, multiple tooling station driving assemblies 40 can be provided on the same side of the conveyor line 10, and the processing equipment assembled on each tooling station driving assembly is different. These processing equipment include but are not limited to, for example, a welding head or a detection camera. In this way, the power battery cover can pass through these processing equipment in sequence while continuously moving on the conveyor line 10, completing a series of predetermined processing operations.

[0053] For another example, if the workpiece on the production line needs to be processed in a more complex manner, or there is mutual interference between different processes, the tooling station driving assemblies 40 can be dispersedly provided on different sides of the conveyor line 10. In this way, by providing multiple tooling station driving assemblies 40 on different sides of the first conveying section 11, the mutual influence between processes can be reduced, thereby improving processing accuracy and efficiency.

[0054] As shown in FIG. 1, the power device 50 is connected to the cam rod 22 to drive the rotation of the cam rod 22, and the power device 50 is also connected to the work station driving assembly 40 to keep the work station driving assembly 40 and the cam rod 22 in coordination. Figure 2

[0055] Specifically, the power device 50 is connected to the cam rod 22 to provide stable and precise rotational power for the cam rod 22. The rotation of the cam rod 22 drives the movement of the cam follower 31 and the carrier 30, thereby achieving precise control of the movement of the carrier 30.

[0056] On the other hand, the power device 50 is also connected to the work station driving assembly 40. This connection ensures that the work station driving assembly 40 can closely match the rotation rhythm of the cam rod 22 and the movement speed of the carrier 30. In this way, the work station driving assembly 40 can adjust the movement speed of the work station in synchronization, achieving a relative stationary state between the workpiece and the processing equipment, i.e., during the movement, the workpiece and the processing equipment can still maintain a stable relative position to carry out precise and efficient processing operations.

[0057] It is worth noting that in the production mode of traditional automated production lines, the work cycle of each work station must include the entire time required for the carrier 30 to move from the previous work station to the current work station, which includes the process of accelerating from stationary to high-speed running and then decelerating to complete stop at the target work station. Such a movement mode not only consumes time, but also increases energy consumption. Secondly, during assembly operations, both the carrier 30 and the workpiece carried by it must be kept stationary. Furthermore, some work stations need to perform additional operations, such as releasing the clamp on the carrier 30, so that the workpiece can be aligned with the positioning device on the work station, and then precise machining or assembly operations can be carried out.

[0058] In the transport processing system 100 of the embodiment of the present application, the machining process of the workpiece can be completed synchronously during the movement of the carrier 30, without waiting for the carrier 30 to completely stop. Such synchronous movement not only improves the overall efficiency of the production line and reduces unnecessary waiting time, but also eliminates the additional energy consumption required for acceleration and deceleration of the carrier 30. More importantly, it can also simplify a part of the process and eliminate the additional operations required for positioning the workpiece, such as opening and closing the clamp, making the entire machining process more smooth and efficient.

[0059] ​Meanwhile, the design of sharing the same power device 50 by the cam lever 22 and the work station driving assembly 40 can also reduce the total demand of the power device 50. In some traditional processing production lines, each processing link often relies on independent motors for driving, resulting in a large number of motors. In the technical scheme of the present application, through integrated design, the single power device 50 simultaneously drives the cam lever 22 and the work station driving assembly 40, effectively reducing the number of motors used, and thereby reducing the overall cost of the transportation processing system 100.

[0060] In addition, such a design also simplifies the complexity of the transportation processing system 100, reduces the difficulty of maintenance work, and thereby prolongs the stable operation period of the system.

[0061] According to some embodiments of the present application, the transportation processing system 100, as shown in Figure 3 The work station driving assembly 40 includes a main shaft 41 and a cam disc 42. The main shaft 41 is in power connection with the power device 50. The cam disc 42 is connected to the main shaft 41 for synchronous rotation, and the cam disc 42 is used for assembly with the processing equipment.

[0062] The output end of the power device 50 is connected with the main shaft 41 to transmit power to the main shaft 41, thereby driving the main shaft 41 to rotate.

[0063] In some optional embodiments, in combination with Figure 3 The power device 50 further includes a speed reducer 57. The speed reducer 57 can reduce the rotation speed of the power device 50 output and increase the torque at the same time, so as to better adapt to the requirements in the processing process. Through the adjustment of the speed reducer 57, the rotation speed of the main shaft 41 can be accurately controlled, thereby further improving the processing precision and efficiency.

[0064] The cam disc 42 is connected to the main shaft 41 to realize the synchronous rotation of the cam disc 42 and the main shaft 41.

[0065] Optionally, the cam disc 42 is sleeved on the main shaft 41. When the main shaft 41 rotates, the cam disc 42 also rotates at the same speed and in the same direction.

[0066] The surface of the cam disc 42 has specific profiles and shapes, which can be adjusted according to the specific requirements of the processing equipment.

[0067] In some optional embodiments, as shown in Figure 3 The main shaft 41 is arranged along the length direction of the first conveying section 11. The cam disc 42 is at least two, and is arranged spaced apart along the length direction of the main shaft 41. At least one cam disc 42 is provided with a cam groove 420 for assembly with the processing equipment.

[0068] In the above technical solution, the main shaft 41 is arranged along the length direction of the first conveying section 11, so that the main shaft 41 can penetrate through the entire first conveying section 11 to provide stable driving force for the workstations. At the same time, the extension of the main shaft 41 also facilitates the connection and assembly with the machining equipment of each workstation, improving the coordination of the entire system.

[0069] At least two cam plates 42 are adopted, and the cam plates 42 are arranged spaced apart along the length direction of the main shaft 41. This design enables each cam plate 42 to independently provide driving force for the corresponding machining equipment, and avoids interference and conflict between different workstations. At the same time, the arrangement of multiple cam plates 42 also improves the flexibility and scalability of the transportation and machining system 100, facilitating the increase or decrease of workstations according to actual needs.

[0070] On at least one cam plate 42, a cam groove 420 specially designed for assembly with the machining equipment is arranged to ensure that the machining equipment can be stably assembled with the cam plate 42. Through the guidance of the cam groove 420, the machining equipment can move accurately with the rotation of the cam plate 42, thereby realizing accurate machining of the workpiece.

[0071] In some optional embodiments, the cam grooves 420 on the two cam plates 42 can provide different motion modes for the machining equipment. This can be achieved by changing the shape and / or size of the cam grooves 420. In this way, the two cam plates 42 can drive different machining equipment respectively, and the cam grooves 420 on each cam plate 42 can provide specific motion modes to adapt to different machining needs. Alternatively, by adjusting the position of the cam plate 42 and the shape of the cam groove 420, the action of the machining equipment can be flexibly adjusted, thereby providing more flexible machining.

[0072] In some optional embodiments, in combination with Figure 3 The cam plate 42 includes a first cam plate 422. The workstation driving assembly 40 further includes an intermittent cam driven plate 43, and the outer circumferential surface of the intermittent cam driven plate 43 includes a plurality of circumferentially spaced apart circular arc segments 431 and linear groove segments 432 connected between adjacent two circular arc segments 431.

[0073] The first cam plate 422 cooperates with the outer circumferential surface of the intermittent cam driven plate 43, and the intermittent cam driven plate 43 remains stationary when the circular arc segment 431 contacts the first cam plate 422, and remains rotating when the linear groove segment 432 contacts the first cam plate 422.

[0074] The first cam plate 422 is one of the components of the workstation driving assembly 40, and it can accurately cooperate with the intermittent cam driven plate 43 to drive the machining equipment to move intermittently. This intermittent movement can ensure that the workpiece is fully processed and positioned during machining.

[0075] The outer circumferential surface of the intermittent cam follower 43 comprises a plurality of circumferentially spaced arc segments 431, which are all tailored in shape and size according to the profile of the first cam disc 422. When the first cam disc 422 comes into contact with the arc segments 431 of the intermittent cam follower 43, the intermittent cam follower 43 will remain stationary, i.e. not perform rotational movement, due to the frictional force between the two. This stationary state provides certain support and positioning for the machining equipment, ensuring the accuracy of the workpiece during the machining process.

[0076] Optionally, the first cam disc 422 comprises a first protrusion 4221 and a second protrusion 4222. The first protrusion 4221 is adapted to contact the linear groove segment 432, and the second protrusion 4222 is adapted to contact the arc segment 431. The first cam disc 422 is sleeved outside the main shaft 41.

[0077] Specifically, when the main shaft 41 starts to rotate and drives the first cam disc 422 sleeved outside to rotate, the first protrusion 4221 will timely enter the linear groove segment 432. During this contact process, the first protrusion 4221 will move along the shape of the linear groove segment 432 and generate the necessary frictional force with the linear groove segment 432. This frictional force not only ensures the stable contact between the two, but also drives the intermittent cam follower 43 to perform rotational movement.

[0078] However, when the first protrusion 4221 continues to move along the rotation direction of the main shaft 41, it will gradually leave the linear groove segment 432. At this time, the second protrusion 4222 will timely contact the arc segment 431 on the intermittent cam follower 43. It is worth noting that the arc design of the second protrusion 4222 is completely consistent with the arc of the arc segment 431. This design makes that when the two are in contact, no additional driving force will be generated between them, so the intermittent cam follower 43 will remain stationary at this contact stage.

[0079] This stationary state will continue until the first protrusion 4221 completes another round of rotation and re-enters the linear groove segment 432. At this moment, the first protrusion 4221 will again generate frictional force with the linear groove segment 432 and drive the intermittent cam follower 43 to perform a new round of rotational movement.

[0080] In the above technical solution, the first protrusion 4221 and the second protrusion 4222 on the first cam disc 422 achieve an intermittent driving mechanism by skillfully contacting and interacting with the linear groove segment 432 and the arc segment 431 on the intermittent cam follower 43. This intermittent driving mechanism ensures the accuracy of the machining equipment during the machining process.

[0081] In some optional embodiments, as Figure 3As shown, the cam plate 42 includes a second cam plate 424. A second cam groove 4241 is defined on the outer circumference of the second cam plate 424. At least two points on the second cam groove 4241 are projected at different angles on the axis of the spindle 41. The workstation drive assembly 40 also includes a rotating support 44 and a rocker arm 45. The rocker arm 45 is rotatably connected to the rotating support 44. One end of the rocker arm 45 engages in the second cam groove 4241, causing it to swing as the second cam plate 424 rotates.

[0082] In the above technical solution, the cam plate 42 includes a second cam plate 424. A second cam groove 4241 is provided on the outer circumference of the second cam plate 424. The projections of at least two points on the second cam groove 4241 on the axis of the main shaft 41 are staggered.

[0083] Optionally, the second cam disc 424 is further provided with a follower 4242. This means that when the second cam disc 424 rotates, the rotation tracks of the follower 4242 in the second cam slot 4241 are not on the same circumference.

[0084] The workstation drive assembly 40 also includes a rotating support 44 and a rocker 45. One end of the rocker 45 is mounted on the rotating support 44 via a rotational connection, while the other end engages within the second cam groove 4241 of the second cam plate 424. When the second cam plate 424 rotates, the rocker 45 is driven by the follower 4242 and rotates according to the contour of the second cam groove 4241.

[0085] With this design, the other end of the swing arm 45 can achieve the same speed as the carrier 30, allowing the processing equipment on the workstation to keep pace with the workpiece on the carrier 30. In this way, when performing operations requiring high-precision positioning, such as welding, inspection and photography, the workstation can move synchronously with the workpiece, ensuring the accuracy of processing or inspection.

[0086] This setting is very suitable for scenarios where the workstation and the workpiece need to remain relatively still.

[0087] For example, during welding operations, the welding head needs to maintain a constant distance from the workpiece surface, or during inspection and photography, the camera needs to remain relatively still relative to the workpiece to obtain a clear image. By precisely controlling the motion of the pendulum 45, synchronized movement between the workstation equipment and the magnetic levitation vehicle can be achieved, thus meeting the requirements of these high-precision operations.

[0088] According to some embodiments of the present invention, the transport processing system 100, such as Figure 4As shown, the power device 50 includes a drive motor 51, a worm 52, a worm gear 53, and a transmission shaft 54. The worm 52 is connected between the drive motor 51 and the cam rod 22. The worm gear 53 is engaged with the worm 52. The transmission shaft 54 is connected at one end to the worm gear 53 and at the other end to the work station driving assembly 40.

[0089] Through the coordinated work of the drive motor 51, the worm 52, the worm gear 53, and the transmission shaft 54, a driving force is formed.

[0090] The worm 52 serves as a component connecting between the drive motor 51 and the cam rod 22, and plays a role in transmitting power. The worm 52 is designed in a spiral structure, which enables the worm 52 to smoothly transmit torque when rotating and effectively reduce the rotational speed, thereby meeting the rotational speed requirements of subsequent transmission components.

[0091] Engaged with the worm 52 is the worm gear 53. The worm gear 53 is a gear with a special tooth shape, which can closely cooperate with the spiral structure of the worm 52 to achieve efficient and stable power transmission. When the worm 52 rotates, the worm gear 53 will rotate with it and transmit power to the subsequent transmission shaft 54 through its tooth structure.

[0092] The transmission shaft 54 is a bridge connecting the worm gear 53 and the work station driving assembly 40. It is closely connected at one end to the worm gear 53 and at the other end to the work station driving assembly 40. Through the rotation of the worm gear 53, the transmission shaft 54 can transmit power to the work station driving assembly 40, thereby driving it to perform various machining operations.

[0093] In the actual operation process of the transportation machining system 100, the drive motor 51 is first started and outputs power.

[0094] On the one hand, the power is transmitted to the worm gear 53 through the worm 52, and the worm gear 53 transmits it to the transmission shaft 54. Finally, the transmission shaft 54 transmits power to the work station driving assembly 40 to drive it to perform various machining operations. In the whole process, the cooperation between the components is tight and gapless, ensuring efficient and stable transmission of power. Moreover, the cooperation structure of the worm 52 and the worm gear 53 has a certain self-locking function, which can prevent reverse rotation or accidental movement to a certain extent.

[0095] On the other hand, the power generated by the drive motor 51 is transmitted to the cam rod 22 through the connecting device.

[0096] Optionally, the connecting device can be a shaft coupling, a belt or chain, a gear, etc.

[0097] In some optional embodiments, referring to Figure 4 , there is a height difference between the worm 52 and the cam rod 22, and the power device 50 further includes a first synchronous belt 55 connected between the two.

[0098] Considering the spatial layout in the transport processing system 100, there can be a certain height difference between the worm 52 and the cam rod 22. In order to overcome this height difference and effectively transmit power from the worm 52 to the cam rod 22, the power device 50 is provided with a first synchronous belt 55.

[0099] The first synchronous belt 55 is a relatively efficient transmission mode, which has the advantages of stable transmission, low noise, high precision and the ability to transmit large torque.

[0100] In some alternative embodiments, the cam rod 22 is provided with a keyless synchronous wheel, and the first synchronous belt 55 is wound outside the keyless synchronous wheel.

[0101] As known to those skilled in the art, the keyless synchronous wheel is a transmission element that does not require the use of traditional keyways or pins for connection, but relies on its special profile shape and material characteristics to achieve close fitting with the shaft, thereby ensuring the stability and reliability of the transmission process. The keyless synchronous wheel can eliminate the stress concentration problem caused by the keyway or pin, thereby prolonging the service life of the transmission component. At the same time, the keyless synchronous wheel has high coaxiality and rotation accuracy, which can ensure that no excessive vibration or noise is generated during rotation, thereby improving the transmission performance of the power device 50.

[0102] In some alternative embodiments, the cam rod 22 is two, and the two cam rods 22 are arranged in parallel, and the carrier 30 is provided with two cam followers 31 to match the two cam rods 22 respectively. The worm 52 is correspondingly provided with two, and the two worms 52 are connected by a second synchronous belt 56, and the two worms 52 are connected to the two cam rods 22 respectively.

[0103] In combination Figure 4 , specifically, the number of cam rods 22 is two, and the two cam rods 22 are arranged in parallel to ensure their stability and consistency in space, which can increase the carrying capacity of the carrier 30.

[0104] In order to match the two cam rods 22, the carrier 30 is also specially constructed with two cam followers 31. The two cam followers 31 correspond to the two cam rods 22 respectively, and can accurately follow the profile of the cam rod 22 to move through close contact and cooperation. This ensures that the carrier 30 can move smoothly and reliably according to the predetermined trajectory, thereby meeting the transmission and processing requirements.

[0105] Meanwhile, in order to effectively transmit power to the two cam rods 22, the number of the worm gears 52 is also two. The two worm gears 52 are connected through the second synchronous belt 56, forming a relatively stable transmission link. Through the connection of the second synchronous belt 56, the two worm gears 52 can maintain the same rotational speed, improve the consistency of the movement of the two cam rods 22, and further enhance the stability and reliability of the carrier 30, thereby facilitating the stability of the workpiece and improving the machining precision.

[0106] According to the transportation machining system 100 of some embodiments of the present application, the two work station driving assemblies 40 are arranged on opposite sides of the first conveying section 11. The power device 50 is one and is connected to the two work station driving assemblies 40.

[0107] The power device 50 is arranged on the same side as one of the work station driving assemblies 40.

[0108] Specifically, the power device 50 includes a driving motor 51, two worm gears 52, two worm wheels 53 and two transmission shafts 54, two first synchronous belts 55 and one second synchronous belt 56.

[0109] In combination Figure 4 , the driving motor 51 directly connects and drives one of the worm gears 52 to rotate. The worm gear 52 is in close engagement with the corresponding worm wheel 53, and transmits the rotational power to the transmission shaft 54 connected thereto. The transmission shaft 54 is then connected to the work station driving assembly 40 on one side, thereby achieving direct driving of the work station driving assembly 40 on the side.

[0110] Meanwhile, the worm gear 52 directly driven by the driving motor 51 is also connected to one of the cam rods 22 through one of the first synchronous belts 55. The first synchronous belt 55 ensures the synchronous rotation between the worm gear 52 and the cam rod 22, thereby achieving accurate power transmission. The worm gear 52 is also connected to the other worm gear 52 through the second synchronous belt 56, forming a bridge for power transmission.

[0111] The other worm gear 52 is connected to the other cam rod 22 through the other first synchronous belt 55, achieving indirect driving of the other cam rod 22. In addition, the worm gear 52 is also engaged with the other worm wheel 53, and the other worm wheel 53 is connected to the other transmission shaft 54, finally driving the work station driving assembly 40 on the other side.

[0112] In this way, the structure of the entire power device 50 is more compact and efficient, and through the use of multiple synchronous belts, the smooth and accurate transmission of power between various components is ensured, thereby improving the stability and reliability of the transportation machining system 100, and also providing certain convenience and flexibility for subsequent maintenance and maintenance.

[0113] In some alternative embodiments, the work station driving assembly 40 further comprises a work station mounting plate 46 disposed on the top. The work station mounting plate 46 is used to mount the processing equipment, so as to improve the stability of the processing equipment in the work station driving assembly 40.

[0114] According to some embodiments of the transport processing system 100 of the present application, the conveying line 10 is a magnetic levitation conveying line.

[0115] The magnetic levitation conveying line can utilize magnetic force to levitate and move the workpiece in a nearly frictionless environment, thereby realizing high-speed, smooth and low-wear workpiece movement.

[0116] Specifically, when the workpiece moves with the carrier 30 to the first conveying section 11. In this area, the movement of the carrier 30 and the driving of the work station driving assembly 40 are controlled by the same power device 50.

[0117] The linkage of the carrier 30 and the work station through the mechanical structure can ensure that the workpiece keeps pace with the processing equipment on the work station during the transmission process. This pace consistency means that the movement speed, direction and position of the workpiece relative to the processing equipment it is about to contact are precisely controlled, so as to achieve the best alignment state at the processing moment.

[0118] In some alternative embodiments, the carrier 30 is a magnetic levitation trolley. The magnetic levitation conveying line comprises the first conveying section 11 and the second conveying section 12.

[0119] When the magnetic levitation trolley enters the first conveying section 11, it moves through the cooperation of the cam follower 31 and the driving groove 221.

[0120] When the magnetic levitation trolley enters the second conveying section 12, it moves on the conveying line 10 through magnetic levitation.
