[0010] The clamping mechanism further includes two second driving members, which are respectively disposed on the two clamping arms and are used to drive the two clamping plates to rotate.

[0011] The posture adjustment platform includes a platform, a third driving component, a fourth driving component, and several limiting plates. The platform is set on the first work station.

[0020] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0021] It should be noted that the terms "comprising" and "having" and any variations thereof in the specification, claims and accompanying drawings of this invention are intended to cover non-exclusive inclusion. For example, a process, method, apparatus, product or device that includes a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such process, method, product or device.

[0022] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail.

[0023] Reference Appendix Figure 1 and Figure 2An automated assembly line is shown, comprising: a frame, on which a conveying mechanism 1, a clamping mechanism 2, a plurality of carrier plates 3, and a plurality of workstations are arranged. The plurality of workstations include a first workstation 4, a second workstation 5, a third workstation 6, a fifth workstation 8, a sixth workstation 9, and a plurality of fourth workstations 7. The first workstation 4, the second workstation 5, the third workstation 6, the plurality of fourth workstations 7, the fifth workstation 8, and the sixth workstation 9 are arranged sequentially in the horizontal direction. The conveying mechanism is used to sequentially convey several carrier plates 3 to the second station 5, the third station 6, several fourth stations 7, the fifth station 8, and the sixth station 9; The first workstation 4 is equipped with a posture adjustment platform, which is used to support the material and adjust the posture of the material. Clamping mechanism 2 is used to transfer materials on the first station 4 to the second station 5 or the third station 6; A rotating platform 81 is provided on both the fifth station 8 and the third station 6. The rotating platform 81 is used to support and rotate the material. A sixth driving component is provided on both the fifth station 8 and the third station 6. The sixth driving component is used to adjust the height of the corresponding rotating platform 81. In this way, when in use, the rotating platform 81 is first raised by the sixth driving component and then rotated, thereby avoiding interference between the main body of the energy storage inverter on the rotating platform 81 and the surrounding components.

[0024] Based on the above structure, during use, the main body of the energy storage inverter is placed on the posture adjustment platform. Then, according to the requirements of the installation accessories (inductor box, heat sink, wiring, etc.), the posture of the main body of the energy storage inverter is adjusted to facilitate installation by the staff. After the relevant accessories are installed, the main body of the energy storage inverter on the first station 4 is transferred to the carrier plate 3 at the third station 6 by the clamping mechanism 2 (if there is already an energy storage inverter on the third station 6 being assembled, the main body of the energy storage inverter on the first station 4 is transferred to the carrier plate 3 at the second station 5). Then, it is transported by the conveying mechanism 1, so that the main body of the energy storage inverter passes through the third station 6, several fourth stations 7 and the fifth station 8 in sequence, and different assembly processes are carried out at each station. Finally, the assembled energy storage inverter arrives at the sixth station 9. This application sets up a posture adjustment platform to adjust the posture of the main body of the energy storage inverter, which is convenient for the staff to operate. Different assembly steps are carried out through different stations. During the assembly process, there is no need to manually move the main body of the energy storage inverter, which reduces the workload of the staff and improves the assembly efficiency.

[0025] like Figures 2-3As shown, the conveying mechanism 1 includes two first lifting components 11 and two linear conveying modules 12. The two first lifting components 11 are respectively located at the second station 5 and the sixth station 9. The two linear conveying modules 12 are arranged parallel to each other in the vertical direction. The two first lifting components 11 are respectively located at the two ends of the two linear conveying modules 12. The two linear conveying modules 12 pass through the third station (6), several fourth stations 7 and fifth stations 8 in sequence. The first lifting components 11 are used to adjust the height of the carrier plate 3 from the linear conveying modules 12. In this way, the carrier plate 3 is reciprocated by the two parallel linear conveying modules 12. When the carrier plate 3 reaches the third station 6 or the sixth station 9, the first lifting components 11 adjust the height of the carrier plate 3. The height of the carrier plate 3 is adjusted to the height of the next linear conveying module 12, thereby realizing the reciprocating conveying of the carrier plate 3. The first lifting component 11 includes a fifth driving component 111, a connecting platform 112, and a third linear module 113. The fifth driving component 111 is used to adjust the height of the connecting platform 112, and the third linear module 113 is used to convey the carrier plate 3 on the connecting platform 112 to one of the linear conveying modules 12. The carrier plate 3 from the linear conveying module 12 is placed on the connecting platform 112. Then the fifth driving component 111 drives the connecting platform 112 and the third linear module 113 to move in height. Then the third linear module 113 transfers the carrier plate 3 on the connecting platform 112, so that the carrier plate 3 is transferred to the linear conveying module 12.

[0026] like Figure 4 and Figure 5 As shown, the clamping mechanism 2 includes a first linear module 21, a second linear module 22, a mounting plate 23, a first drive member, two clamping arms 24, two clamping plates 25, and two second drive members 26. The first linear module 21 is mounted on the frame and extends horizontally (passing above the first station 4, the second station 5, and the third station 6). The second linear module 22 is mounted on the first linear module 21 and extends vertically. The mounting plate 23 is mounted on the second linear module 22, and the two clamping arms 24 are mounted on the mounting plate 23. The first drive members are used to drive the two clamping arms 24 to move towards or away from each other. The two clamping plates 25 are respectively located on the sides of the two clamping arms 24 that are close to each other. The two second driving members 26 are respectively located on the two clamping arms 24. The two second driving members 26 are used to drive the two clamping plates 25 to rotate. In use, the horizontal position and height of the mounting plate 23 are adjusted by the first linear module 21 and the second linear module 22 respectively. The first driving member drives the two clamping arms 24 to move towards each other to clamp the main body of the energy storage inverter (the two clamping plates 25 are located on both sides of the main body of the energy storage inverter, and the sides of the two clamping plates 25 that are close to each other are provided with pads to avoid damaging the main body of the energy storage inverter). Then the main body of the energy storage inverter is transported.

[0027] like Figure 6 and Figure 7 As shown, the posture adjustment platform includes a platform 41 (preferably disc-shaped), a third drive unit 42, a fourth drive unit 43, and several limiting plates 44. The platform 41 is set on the first workstation 4. The third drive unit 42 is used to drive the platform 41 to rotate, and the fourth drive unit 43 is used to drive the platform 41 to rise and fall (the platform 41 can be adjusted to the required height as needed to meet different processing requirements, and can be adapted to workers of different heights). Several limiting plates 44 are set on the platform 41, and the top of the limiting plates 44... Each component is provided with a first limiting groove 441, and several first limiting grooves 441 form a material limiting space (in this embodiment, the material limiting space is cuboid in shape, and several limiting plates 44 are respectively provided on the periphery of the material limiting space; at least two limiting plates 44 are provided on each side of the material limiting space). In this way, the energy storage inverter body is supported by several limiting plates 44, and the first limiting grooves 441 restrict the position of the energy storage inverter, so as to prevent the position of the energy storage inverter body from changing when assembling parts; and several part jigs 45 (parts) are provided on the platform 41. The fixture 45 is made of bakelite and anodized aluminum in different colors. While aesthetically pleasing, it also helps to distinguish and place inductors and heat sinks of different specifications, preventing employees from misplacing them and wasting time. Its main advantage is that it can fix and limit the positions of all different inductors, heat sinks, and enclosures at once. Once the main body of the energy storage inverter is placed, the corresponding mounting holes on each component and enclosure will be accurately aligned. Only one employee needs to easily drive in the fixing screws with a screwdriver, significantly saving assembly time and employee effort. The top of the fixture 45 has a second limiting groove 451. This design allows for pre-positioning of components on the fixture 45 based on their installation position on the main body of the energy storage inverter (the position of the fixture 45 and the shape and size of the second limiting groove 451 are adaptively set according to the actual installation position, shape, and size of the components). Then, the main body of the energy storage inverter is placed in the material limiting space. At this point, the positions of the components and the main body do not need to be adjusted; they can be directly fixed, thus improving the efficiency of component assembly.

[0028] like Figure 6 As shown, the platform 41 is equipped with several lifting cylinders 46, and each lifting cylinder 46 is equipped with a lifting plate 461 at its top. The advantage of setting up lifting cylinders 46 is that when it is necessary to assemble the main body of the energy storage inverter from the bottom, the main body of the energy storage inverter can be raised and then operated, thus expanding the operating space.

[0029] like Figure 7As shown, the third driving component 42 includes a driving gear 421, a driven gear 422, and a motor 423. The driving gear 421 is mounted on the output shaft of the motor 423 and is located at the bottom of the platform 41. The driving gear 421 and the driven gear 422 mesh. Thus, by clicking the motor 423, the driving gear 422 is driven to rotate, which in turn causes the driven gear 422 to rotate, thereby realizing the rotation of the platform 41.

[0030] A further optimization is that the first workstation 4 is equipped with a material rack 47 and an electric screwdriver rack 48 on one side of the platform 41 for placing materials and corresponding parts to facilitate operation by the staff.

[0031] A further optimization is that the bottom of the first workstation 4 is equipped with several first universal wheels 49. By setting several first universal wheels 49, the first workstation 4 can be moved according to needs, thereby improving flexibility.

[0032] like Figure 2 , Figure 8 as well as Figure 9 As shown, this application also includes a mobile cart 10, on which a support platform is provided. The support platform includes two support rods 101 and several conveying rollers 102. The several conveying rollers 102 are arranged side by side between the two support rods 101. Several second universal wheels 103 are provided at the bottom of the mobile cart 10. Thus, in use, the mobile cart 10 is placed on one side of the sixth work station 9, and the height of the carrier plate 3 is adjusted to be consistent with the height of the support platform by the first lifting component 11 at the sixth work station 9. Then, the carrier plate 3 is conveyed to the top of the several conveying rollers 102, so that the assembled energy storage inverter is moved onto the mobile cart 10. Then, the trolley is pushed to transfer the energy storage inverter to the designated position, which improves the transfer efficiency of the energy storage inverter and reduces the physical labor of the staff.

[0033] In a further optimization, two support platforms are preferably provided in this embodiment, arranged sequentially from top to bottom, so that the mobile vehicle 10 can transport two energy storage inverters at the same time, thereby improving the transport efficiency.

[0034] A further optimization is that a lever 104 is provided on one side of the mobile cart 10, allowing staff to easily push and pull the mobile cart 10 by holding the lever 104.

[0035] like Figure 8 and Figure 9As shown, a positioning component is provided on the side of the mobile carriage 10 away from the pull rod 104. The positioning component includes two positioning plates 105, which are arranged sequentially in the horizontal direction. A limit component is provided on one side of the sixth station 9. The limit component includes two limit pins 92, which are arranged sequentially in the horizontal direction. The distance between the two limit pins 92 is adapted to the two positioning plates 105. The advantage of this design is that when the mobile carriage 10 is attached to one side of the sixth station 9, the two positioning plates 105 are inserted into the inside of the two limit pins 92, so that the mobile carriage 10 and the sixth station 9 are precisely connected, ensuring that the carrier plate 3 accurately reaches the top of the support platform. Another function of the mobile carriage 10 is to transport the empty carrier plate 3 back to the sixth station 9, and then the empty carrier plate 3 returns to the conveying process of the conveying mechanism 1.

[0036] And in order to improve security, such as Figure 8 and Figure 9 As shown, the side of the mobile carriage 10 away from the pull rod 104 is provided with a first insertion hole 106, and the side of the sixth station 9 is provided with a connecting plate 93, on which a second insertion hole 91 is provided. When the two positioning plates 105 are placed between the two limit pins 92, the first insertion hole 106 and the second insertion hole 91 are coaxial, and a plug rod 107 is inserted into the first insertion hole 106 and the second insertion hole 91. The advantage of this design is that when the mobile carriage 10 is docked to the side of the sixth station 9, the plug rod 107 is inserted into the first insertion hole 106 and the second insertion hole 91 to fix the position of the mobile carriage 10 and prevent the mobile carriage 10 from being misaligned. Furthermore, a sensor is provided on the sixth station 9 to detect whether a plug rod 107 is inserted at the second insertion hole 91. The sensor can be an infrared sensor, etc. The sensor detects whether the insertion rod 107 is inserted at the second insertion hole 91, thus ensuring that the insertion rod 107 is not inserted, which would cause problems in the subsequent transfer of the carrier plate (the sensor will only give a signal after the insertion rod 107 is inserted into the first insertion hole 106 and the second insertion hole 91, indicating that the moving cart 10 is in place and safe, and the carrier plate carrying the product can be raised to the required height and sent to the moving cart); and the moving cart 10 is provided with a third insertion hole 108. When the moving cart 10 leaves the sixth work station, the insertion rod 107 is inserted into the third insertion hole 108 for temporary placement of the insertion rod 107. At the same time, it can also prevent the carrier plate 3 and the workpiece products on it from rolling directly to the ground due to inertia when the moving cart 10 is pulled, which would cause product damage and personnel injury.

[0037] Further optimization involves using aluminum alloy coated material for the entire production line. Each workstation is equipped with a blocking cylinder to brake the carrier plate 3 and mitigate the impact generated during its operation. Each workstation is also equipped with a wired electrostatic wrist strap connected to a dedicated human static grounding system (ESD) to ensure that static electricity generated by operators can be promptly conducted to the ground through this line, preventing damage to chips or other electronic components on the PCBA and further ensuring product quality.

[0038] Further optimization involves the production line employing two adjustable modes: free-cycle and forced-cycle. When trial production of new products encounters difficulties or new employees lack the necessary skills to keep up with the pace, the free-cycle mode can be used. After each process is completed, the worker operates a dedicated button switch to allow the energy storage inverter to proceed to the next process, then continues assembling the next unit, reducing unnecessary waiting time and preventing the current process from being hindered by incomplete work in other processes. When the production line is mass-producing mature products and employee proficiency is sufficient, a "workstation cycle time" can be set based on the balanced working hours of the IE test, enabling a fixed mode. Each workstation must complete its corresponding work within the set time, directly and significantly improving overall efficiency. In addition to installing the necessary testing equipment, the production line is also equipped with ion fans. The ion wind blown out can eliminate static electricity on the human body and product surface, preventing or reducing the safety hazards caused by static electricity to the product. The above are merely preferred embodiments of this application, and the present invention is not limited to the above embodiments. It is understood that other improvements and variations that are directly derived or conceived by those skilled in the art without departing from the spirit and concept of the present invention should be considered to be included within the protection scope of the present invention.
