For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0033] Reference below Figure 1 - Figure 4 A transport processing system 100 according to an embodiment of the present invention is described.
[0034] The application scenario of the transportation and processing system 100 according to the embodiment of the present invention is not limited, and it can be used to process a variety of workpieces, such as power battery covers, or to process other components that require high-precision positioning and rapid transmission, such as electronic components, precision mechanical parts, etc.
[0035] The present invention is described by taking the transportation and processing system 100 for processing a power battery cover plate as an example, which will not be described in detail below.
[0036] like Figure 1 As shown, the transport processing system 100 according to the embodiment of the present invention includes: a conveyor line 10 , a first conveying mechanism 20 , a carrier 30 for mounting workpieces, a workstation driving assembly 40 and a power device 50 .
[0037] Here, the conveyor line 10 is extended along a first direction.
[0038] The conveyor line 10 includes at least one first conveyor section 11. The first conveyor section 11 can be flexibly located at an upstream rear section, a middle section, or a downstream front section of the conveyor line 10.
[0039] In some Figure 1 In the illustrated embodiment, the first conveying section 11 is a middle section of the conveying line 10 .
[0040] The first conveying mechanism 20 is arranged on the first conveying section 11. Figure 2 As shown, the first conveying mechanism 20 includes a cam rod 22 , which is arranged along the conveying line 10 , and a driving groove 221 is provided on the cam rod 22 , and the driving groove 221 is spirally extended around the axis of the cam rod 22 .
[0041] When the cam rod 22 is driven by external power to rotate, the driving slot 221 rotates around its axis as the cam rod 22 rotates. At this time, the component matched with the driving slot 221 can move along the path of the driving slot 221 in the length direction of the cam rod 22.
[0042] Combination Figure 2 The carrier 30 is assembled on the conveyor line 10 to transport the workpiece. The carrier 30 is provided with a cam follower 31 . When the carrier 30 moves to the first conveying section 11 , the cam follower 31 cooperates with the driving groove 221 .
[0043] It should be noted that, in the transport processing system 100 , the carrier 30 is assembled on the conveyor line 10 to transport, for example, power battery covers, components or other workpieces that need to be transported.
[0044] The function of the carrier 30 is to ensure that the workpiece can move smoothly along the predetermined path. When the carrier 30 moves along the conveyor line 10 to the first conveying section 11, the cam follower 31 carried by the carrier 30 will cooperate with the driving groove 221 set on the cam rod 22.
[0045] Optionally, the shape and size of the cam follower 31 are adapted to the driving slot 221. This ensures that the two can fit together. The matching mechanism of the cam follower 31 and the driving slot 221 enables the driving slot 221 to guide the cam follower 31 to move along its spiral path when the cam rod 22 rotates under the drive of external power. The movement of the cam follower 31 will further drive 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, and each tooling station will perform corresponding processing on the workpiece according to a preset processing flow.
[0047] In this way, the movement of the carrier 30 in the first conveying section 11 is continuous and controllable, and the carrier 30 can be accurately conveyed to the designated location for processing or other operations, while maintaining the stability of the material on the carrier 30, reducing the error caused by speed fluctuations during the conveying process.
[0048] Optionally, the spiral angle and shape of the driving groove 221 can be adjusted as required. By adjusting the spiral angle and shape, the movement 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 high-precision transmission effect.
[0049] The workstation drive assembly 40 is disposed on at least one side of the first conveying section 11 and is used to assemble a processing device to process a workpiece.
[0050] The workstation drive assembly 40 can be used to support and drive the assembly processing assembly to achieve processing of the workpiece moving on the conveyor line 10.
[0051] In some optional embodiments, there are multiple workstation drive assemblies 40. The multiple workstation drive assemblies 40 can be arranged on the same side or different sides of the first conveying section 11.
[0052] For example, in a power battery cover processing line, it may be necessary to set up multiple workstation drive assemblies 40 on the same side of the conveyor line 10, and the processing equipment installed on each workstation drive assembly is different, including but not limited to welding heads or detection cameras, etc. In this way, when the power battery cover continuously moves on the conveyor line 10, it can pass through these processing equipment in turn to complete a series of predetermined processing operations.
[0053] For another example, if the workpieces on the production line need to be processed more complicatedly, or there is mutual interference between different processes, the workstation drive components 40 can be dispersedly arranged on different sides of the conveyor line 10. In this way, arranging multiple workstation drive components 40 on different sides of the first conveyor section 11 can reduce the mutual influence between the processes, thereby improving the processing accuracy and efficiency.
[0054] like Figure 2 As shown, the power device 50 is connected to the cam rod 22 to drive the cam rod 22 to rotate, and the power device 50 is connected to the workstation drive assembly 40 to keep the workstation drive assembly 40 and the cam rod 22 in coordinated motion.
[0055] Specifically, the power device 50 is connected to the cam rod 22 on one hand, providing stable and precise rotational power for the cam rod 22. The rotation of the cam rod 22 drives the cam follower 31 and the carrier 30 to move, 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 workstation drive assembly 40. This connection ensures that the workstation drive assembly 40 can closely match the rotation rhythm of the cam rod 22 and the moving speed of the carrier 30. In this way, the workstation drive assembly 40 can synchronously adjust the moving speed of the workstation to achieve a relative static state between the processing equipment and the workpiece, that is, during the movement process, the workpiece and the processing equipment can still maintain a stable relative position, so as to perform accurate and efficient processing operations.
[0057] It is worth noting that in the production mode of the traditional automated production line, the working cycle of each workstation must include the total time required for the carrier 30 to move from the previous workstation to the current workstation, which includes the process of the carrier 30 accelerating from rest to high-speed operation, and then decelerating to a complete stop at the target workstation. Such a movement mode is not only time-consuming, but also increases energy consumption. Secondly, during assembly operations, both the carrier 30 and the workpiece it carries must remain stationary. What's more, some workstations require additional operations, such as releasing the fixture on the carrier 30 so that the workpiece can be aligned with the positioning device on the workstation before precise processing or assembly operations can be performed.
[0058] In the transport processing system 100 of the embodiment of the present invention, the processing of the workpiece can be completed synchronously during the movement of the carrier 30, without waiting for the carrier 30 to stop completely. This synchronous movement not only improves the overall efficiency of the production line and reduces unnecessary waiting time, but also eliminates the extra energy consumption required for acceleration and deceleration of the carrier 30. More importantly, it can also simplify part of the process, eliminating the extra operations required for positioning the workpiece, such as opening and closing the fixture, making the entire processing process smoother and more efficient.
[0059] At the same time, the design that the cam rod 22 and the station drive assembly 40 share the same power device 50 can also reduce the total demand for the power device 50. In some traditional processing production lines, each processing link often relies on an independent motor for driving, resulting in a large number of motors. In the technical solution of the present invention, through integrated design, a single power device 50 can be used to drive the cam rod 22 and the station drive assembly 40 at the same time, effectively reducing the number of motors used, thereby reducing the overall cost expenditure of the transportation processing system 100.
[0060] In addition, such a design simplifies the complexity of the transportation and processing system 100, reduces the difficulty of maintenance work, and thus extends the stable operation cycle of the system.
[0061] According to some embodiments of the present invention, the transport processing system 100, such as Figure 3 As shown, the station drive assembly 40 includes: a main shaft 41 and a cam plate 42. The main shaft 41 is connected to the power device 50. The cam plate 42 is connected to the main shaft 41 to rotate synchronously, and the cam plate 42 is used to be assembled with the processing equipment.
[0062] The output end of the power device 50 is connected to 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, combined with Figure 3 The power device 50 also includes a reducer 57. The reducer 57 can reduce the speed output by the power device 50 and increase the torque to better meet the needs of the processing process. Through the adjustment of the reducer 57, the rotation speed of the spindle 41 can be accurately controlled, thereby further improving the processing accuracy and efficiency.
[0064] The cam plate 42 is connected to the main shaft 41 to achieve synchronous rotation of the cam plate 42 and the main shaft 41 .
[0065] Optionally, the cam plate 42 is sleeved outside the main shaft 41. When the main shaft 41 rotates, the cam plate 42 also rotates at the same speed and direction.
[0066] The surface of the cam plate 42 has a specific profile and shape, and these profiles and shapes can be adjusted according to the specific requirements of the processing equipment.
[0067] In some optional embodiments, such as Figure 3 As shown, the main shaft 41 is extended along the length direction of the first conveying section 11. There are at least two cam plates 42, which are spaced apart along the length direction of the main shaft 41, and at least one cam plate 42 is provided with a cam groove 420 for assembly with a processing device.
[0068] In the above technical solution, the main shaft 41 is extended along the length direction of the first conveying section 11, so that the main shaft 41 can run through the entire first conveying section 11, providing a stable driving force for the workstation. At the same time, the extended setting of the main shaft 41 is also convenient for connection and assembly with the processing equipment of each workstation, thereby improving the coordination of the entire system.
[0069] At least two cam plates 42 are used, and these cam plates 42 are 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 processing equipment, and avoids interference and conflict between different workstations. At the same time, the provision of multiple cam plates 42 also improves the flexibility and scalability of the transport processing system 100, making it easy to increase or decrease workstations according to actual needs.
[0070] On at least one cam plate 42, a cam groove 420 is specially designed for assembly with a processing device to ensure that the processing device can be stably assembled with the cam plate 42. Guided by the cam groove 420, the processing device can move accurately with the rotation of the cam plate 42, thereby achieving accurate processing of the workpiece.
[0071] In some optional embodiments, the cam grooves 420 on the two cam discs 42 can provide different motion modes for the processing equipment. This can be achieved by changing the shape and / or size of the cam grooves 420. In this way, the two cam discs 42 can drive different processing equipment respectively, and the cam grooves 420 on each cam disc 42 can provide specific motion modes to adapt to different processing requirements. Alternatively, by adjusting the position of the cam disc 42 and the shape of the cam grooves 420, the action of the processing equipment can be flexibly adjusted, thereby providing more flexible processing.
[0072] In some optional embodiments, combined with Figure 3 The cam plate 42 includes a first cam plate 422. The station drive assembly 40 also includes an intermittent cam follower plate 43, and the outer peripheral surface of the intermittent cam follower plate 43 includes a plurality of circumferentially spaced arc segments 431 and a line groove segment 432 connected between two adjacent arc segments 431.
[0073] The first cam plate 422 cooperates with the outer circumferential surface of the intermittent cam follower plate 43 , and the intermittent cam follower plate 43 remains stationary when the arc segment 431 contacts the first cam plate 422 , and keeps rotating when the line groove segment 432 contacts the first cam plate 422 .
[0074] As one of the components of the station drive assembly 40, the first cam plate 422 can achieve precise cooperation with the intermittent cam follower plate 43, thereby driving the processing equipment to perform intermittent motion. This intermittent motion can ensure that the workpiece is fully processed and positioned during the processing.
[0075] The outer peripheral surface of the intermittent cam follower 43 includes a plurality of circular arc segments 431 spaced apart in the circumferential direction, and the shapes and sizes of these circular arc segments 431 are customized according to the profile of the first cam disc 422. When the first cam disc 422 contacts the circular arc segment 431 of the intermittent cam follower 43, due to the friction between the two, the intermittent cam follower 43 will remain in a rest state, that is, it will not rotate. This rest state provides certain support and positioning for the processing equipment, ensuring the accuracy of the workpiece during the processing.
[0076] Optionally, the first cam plate 422 includes: a first convex portion 4221 and a second convex portion 4222. The first convex portion 4221 is suitable for contacting the wire groove segment 432, and the second convex portion 4222 is suitable for contacting the arc segment 431. The first cam plate 422 is sleeved outside the main shaft 41.
[0077] Specifically, when the main shaft 41 starts to rotate and drives the first cam plate 422 sleeved thereon to rotate together, the first protrusion 4221 will timely enter the wire groove segment 432. During this contact process, the first protrusion 4221 will move along the shape of the wire groove segment 432 and generate necessary friction with the wire groove segment 432. This friction not only ensures stable contact between the two, but also drives the intermittent cam follower plate 43 to rotate.
[0078] However, when the first protrusion 4221 continues to move along the rotation direction of the main shaft 41, it will gradually leave the line groove segment 432. At this time, the second protrusion 4222 will timely contact the arc segment 431 on the intermittent cam follower plate 43. It is worth noting that the arc design of the second protrusion 4222 is completely consistent with the arc shape of the arc segment 431. This design ensures that when the two are in contact, no additional driving force will be generated between them, so the intermittent cam follower plate 43 will remain stationary during this contact stage.
[0079] This static state will continue until the first convex portion 4221 completes another rotation and re-enters the wire groove section 432. At this moment, the first convex portion 4221 will again generate friction with the wire groove section 432 and drive the intermittent cam driven plate 43 to perform a new round of rotational motion.
[0080] In the above technical solution, the first convex portion 4221 and the second convex portion 4222 on the first cam plate 422 are in contact with and interact with the line groove segment 432 and the arc segment 431 on the intermittent cam follower plate 43 to realize an intermittent driving mechanism. This intermittent driving mechanism ensures the accuracy of the processing equipment during the processing.
[0081] In some optional embodiments, such as Figure 3As shown, the cam plate 42 includes a second cam plate 424. A second cam plate 4241 is provided on the outer circumference of the second cam plate 424, and at least two points on the second cam plate 4241 are projected on the axis of the main shaft 41 at different angles. The station drive assembly 40 also includes a rotating support 44 and a swing rod 45. The swing rod 45 is rotatably connected to the rotating support 44, and one end of the swing rod 45 is engaged in the second cam plate 4241 to swing with the rotation of the second cam plate 424.
[0082] In the above technical solution, the cam plate 42 includes a second cam plate 424. A second cam plate 4241 is provided on the outer circumference of the second cam plate 424, and the projections of at least two points on the second cam plate 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 track of the follower 4242 in the second cam disc 4241 is not on the same circumference.
[0084] The station drive assembly 40 further includes: a rotating support 44 and a swing rod 45. One end of the swing rod 45 is mounted on the rotating support 44 through a rotating connection, and the other end is fitted in the second cam plate 4241 of the second cam plate 424. When the second cam plate 424 rotates, the swing rod 45 is driven by the follower 4242 and rotates according to the profile of the second cam plate 4241.
[0085] Through this design, the other end of the swing rod 45 can achieve the same speed as the carrier 30, so that the processing equipment on the workstation can keep pace with the workpiece on the carrier 30. In this way, when performing operations that require high-precision positioning, such as welding, inspection and photography, the workstation can move synchronously with the workpiece to ensure 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, when performing welding operations, the welding head needs to maintain a constant distance from the workpiece surface, or when performing inspection and taking photos, the camera needs to remain relatively still with the workpiece to obtain a clear image. By accurately controlling the movement law of the swing rod 45, the synchronous movement between the workstation equipment and the magnetic suspension vehicle can be achieved, thereby 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 driving motor 51, a worm 52, a worm wheel 53 and a transmission shaft 54. The worm 52 is connected between the driving motor 51 and the cam rod 22. The worm wheel 53 meshes with the worm 52. One end of the transmission shaft 54 is connected to the worm wheel 53 and the other end is connected to the workstation drive assembly 40.
[0089] The driving motor 51 , the worm 52 , the worm wheel 53 and the transmission shaft 54 work together to form a driving force.
[0090] The worm 52 is a component connecting the drive motor 51 and the cam rod 22, and plays a role in transmitting power. The design of the worm 52 adopts a spiral structure, which enables the worm 52 to smoothly transmit torque when rotating and effectively reduce the speed, thereby meeting the speed requirements of subsequent transmission components.
[0091] The worm gear 53 is meshed with the worm 52. 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 accordingly 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 workstation drive assembly 40. One end of the transmission shaft 54 is closely connected to the worm gear 53, and the other end is connected to the workstation drive assembly 40. Through the rotation of the worm gear 53, the transmission shaft 54 can transmit power to the workstation drive assembly 40, thereby driving it to perform various processing operations.
[0093] During the actual operation of the transport processing system 100 , the drive motor 51 is first started and outputs power.
[0094] On the one hand, the power is transmitted to the worm wheel 53 through the worm 52, and the worm wheel 53 transmits it to the transmission shaft 54. Finally, the transmission shaft 54 transmits the power to the workstation drive assembly 40, driving it to perform various processing operations. During the whole process, the various components cooperate closely to ensure efficient and stable transmission of power. Moreover, the matching structure of the worm 52 and the worm wheel 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 driving motor 51 is transmitted to the cam rod 22 through the connecting device.
[0096] Alternatively, the connecting device may be a coupling, a belt or chain, a gear or the like.
[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 also includes a first synchronous belt 55 connected between the two.
[0098] Considering the spatial layout in the transport processing system 100 , there may be a certain height difference between the worm gear 52 and the cam rod 22 . In order to overcome this height difference and effectively transfer power from the worm gear 52 to the cam rod 22 , a first synchronous belt 55 is added to the power device 50 .
[0099] The first synchronous belt 55 is a relatively efficient transmission method, which has the advantages of stable transmission, low noise, high precision and the ability to transmit a large torque.
[0100] In some optional embodiments, a keyless synchronous wheel is provided on the cam rod 22, and the first synchronous belt 55 is wound around 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, but relies on its special profile shape and material characteristics to achieve close fit with the shaft, thereby ensuring stability and reliability during the transmission process. The keyless synchronous wheel can eliminate the stress concentration problem caused by the keyway or pin, thereby extending the service life of the transmission parts. At the same time, the keyless synchronous wheel has a 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 optional embodiments, there are two cam rods 22, the two cam rods 22 are arranged in parallel, and two cam followers 31 are provided on the carrier 30 to respectively cooperate with the two cam rods 22. Two worm gears 52 are correspondingly provided, and the two worm gears 52 are connected by a second synchronous belt 56, and the two worm gears 52 are respectively connected to the two cam rods 22.
[0103] Combination Figure 4 Specifically, there are two cam rods 22 , 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, two cam followers 31 are also specially configured on the carrier 30. The two cam followers 31 correspond to the two cam rods 22 respectively, and through close contact and matching, can accurately follow the contour of the cam rods 22 to move. This ensures that the carrier 30 can move smoothly and reliably according to the predetermined trajectory, thereby meeting the transmission and processing requirements.
[0105] At the same time, in order to effectively transmit power to the two cam rods 22, the number of worm gears 52 is also two. The two worm gears 52 are connected by a second synchronous belt 56 to form a relatively stable transmission link. Through the connection of the second synchronous belt 56, the two worm gears 52 can maintain a synchronous rotation speed, improve the consistency of the movement of the two cam rods 22, further enhance the stability and reliability of the carrier 30, thereby facilitating the stability of the workpiece and further improving the processing accuracy.
[0106] According to some embodiments of the transportation and processing system 100 of the present invention, there are two workstation drive assemblies 40 disposed on opposite sides of the first conveying section 11. There is one power device 50 connected to the two workstation drive assemblies 40.
[0107] The power device 50 is arranged on the same side as one of the workstation drive assemblies 40 .
[0108] Specifically, the power device 50 includes: a driving motor 51 , two worms 52 , two worm wheels 53 , two transmission shafts 54 , two first synchronous belts 55 and one second synchronous belt 56 .
[0109] Combination Figure 4 The drive motor 51 is directly connected to and drives one of the worms 52 to rotate. The worm 52 is tightly meshed with the corresponding worm wheel 53, and the rotational power is transmitted to the transmission shaft 54 connected thereto. The transmission shaft 54 is then connected to the workstation drive assembly 40 on one side, thereby directly driving the workstation drive assembly 40 on the side.
[0110] At the same time, the worm 52 directly driven by the driving motor 51 is also connected to one of the cam rods 22 through a first synchronous belt 55. The first synchronous belt 55 ensures the synchronous rotation between the worm 52 and the cam rod 22, thereby achieving accurate power transmission. The worm 52 is also connected to another worm 52 through a second synchronous belt 56, forming a bridge for power transmission.
[0111] Another worm 52 is connected to another cam rod 22 through another first synchronous belt 55, thereby indirectly driving the other cam rod 22. In addition, the worm 52 is also meshed with another worm gear 53, which is in turn connected to another transmission shaft 54, and finally drives the workstation drive assembly 40 on the other side.
[0112] In this way, the structure of the entire power device 50 is made more compact and efficient, and the use of multiple synchronous belts ensures smooth and accurate transmission of power between various components, thereby improving the stability and reliability of the transportation and processing system 100, while also providing certain convenience and flexibility for subsequent maintenance.
[0113] In some optional embodiments, the workstation drive assembly 40 further includes a workstation mounting plate 46 disposed on the top. The workstation mounting plate 46 is used to mount processing equipment to improve the stability of the processing equipment in the workstation drive assembly 40.
[0114] According to the transportation and processing system 100 of some embodiments of the present invention, the conveyor line 10 is a magnetic levitation conveyor line.
[0115] The magnetic levitation conveyor line can use magnetic force to suspend and move the workpiece in an almost frictionless environment, thereby achieving high-speed, smooth and low-wear workpiece movement.
[0116] Specifically, when the workpiece moves to the first conveying section 11 along with the carrier 30 , in this area, the movement of the carrier 30 and the driving of the workstation driving assembly 40 are controlled by the same power device 50 .
[0117] The linkage between the carrier 30 and the workstation is realized through the mechanical structure, which can ensure that the workpiece keeps pace with the processing equipment on the workstation during the transmission process. This kind of pace means that the moving 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 moment of processing.
[0118] In some optional embodiments, the carrier 30 is a magnetic levitation vehicle. The magnetic levitation conveyor line includes a first conveying section 11 and a second conveying section 12 .
[0119] When the magnetic suspension vehicle enters the first conveying section 11 , it moves through the cooperation between the cam follower 31 and the driving groove 221 .
[0120] When the magnetic suspension vehicle enters the second conveying section 12, it moves on the conveying line 10 through magnetic suspension.
