DETAILED DESCRIPTION

[0024] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0025] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0026] like Figures 1 to 4 As shown, an inverter assembly device includes a base 100, a product placement rack 200, a tightening device 300, a detection component 400, a driving device 500 and a pressing component 600.

[0027] like Figures 1 to 4 As shown, an inverter assembly device includes:

[0028] Base 100, including a loading area and a processing area;

[0029] The product placement rack 200 is movably mounted on the base 100 and moves between the loading area and the processing area to transfer the inverter 700 to the processing area. The inverter 700 is provided with a plurality of electrical connectors 710 to be fastened.

[0030] The tightening device 300 is movably arranged in the processing area, and includes a tightening assembly 310 for tightening the electrical connector 710, and the tightening assembly 310 is provided with a clamping connector 311 adapted to the electrical connector 710;

[0031] The detection assembly 400 is located in the loading area and is in communication with the tightening assembly 310. It is used to detect the posture of the electrical connector 710 and generate a detection signal to feed back to the tightening assembly 310. When the tightening assembly 310 receives the detection signal, it drives the clamping connector 311 to adjust to a posture that matches the posture of the electrical connector 710. This allows the clamping connector 311 of the tightening assembly 310 to accurately mate with the electrical connector 710 in any posture, greatly improving the accuracy and efficiency of tightening the electrical connector 710, reducing the need for manual intervention, and lowering production costs.

[0032] Specifically, if Figures 1 to 4 As shown, in this embodiment, the base 100 is groove-shaped and includes a loading area and a processing area, providing a support platform for the entire inverter 700 assembly equipment. It should be noted that in this embodiment, the loading area is also used as a unloading area.

[0033] In order to realize the automatic transmission of the inverter 700, in this embodiment, it includes a product placement rack 200 movably arranged on the base 100. The product placement rack 200 is provided with two groups and is movably arranged in a recessed position of the base 100 through a driving device 500. It is responsible for transporting the product placement rack 200 installed with the inverter 700 from the loading area to the processing area, and the driving device 500 can drive the two groups of product placement racks 200 to move alternately. While realizing the automatic transmission of the inverter 700, it improves the efficiency of loading and processing, reduces waiting time, and improves the overall efficiency of the production line.

[0034] In this embodiment, the driving device 500 includes a first rail 510 and a second rail 520 detachably provided on the base 100, a first sliding plate 530 movably provided on the first rail 510, a second sliding plate 540 movably provided on the second rail 520, and a fourth driving structure 550 for driving the first sliding plate 530 and the second sliding plate 540 to move in opposite directions, and a fifth driving structure 560 for driving the second sliding plate 540 to move longitudinally. The two groups of product placement racks 200 are respectively provided on the first sliding plate 530 and the second sliding plate 540, and there is a height difference between the first rail 510 and the second rail 520, which avoids interference between the first sliding plate 530 and the second sliding plate 540 when they move alternately, thereby effectively ensuring the accuracy, controllability and flexibility of the movement of the two groups of product placement racks 200.

[0035] In this embodiment, the height of the first rail 510 is higher than the height of the second rail 520, and the second rail 520 is arranged inside the first rail 510. When the first sliding plate 530 and the second sliding plate 540 move alternately, the fourth driving structure 550 drives the first sliding plate 530 to move along the length direction of the first rail 510, and the second sliding plate 540 moves below the first sliding plate 530 along the length direction of the second rail 520 in the opposite direction of the first sliding plate 530. When the second sliding plate 540 moves to the processing area and the first sliding plate 530 moves to the loading area, the fifth driving structure 560 drives the second sliding plate 540 to move up to the same height as the first sliding plate 530. After the assembly operation is completed, the fifth driving structure 560 drives the second sliding plate 540 to move down to the height position of the first sliding plate 530, and then moves alternately again under the drive of the fourth driving structure 550.

[0036] Preferably, in this embodiment, the fourth driving structure 550 includes a transmission belt, a rotating shaft and a driving motor. The first sliding plate 530 and the second sliding plate 540 are respectively connected to the transmission belt and move in opposite directions under the drive of the driving motor.

[0037] Preferably, in this embodiment, the fifth driving structure 560 includes a lifting rod, a movable plate and a driving motor. One end of the lifting rod is connected to the second sliding plate 540, and the other end is connected to the movable plate. The second sliding plate 540 is connected to the transmission belt through the movable plate and moves longitudinally under the drive of the driving motor.

[0038] In this embodiment, the inverter 700 is mounted on the product placement rack 200, and a plurality of electrical connectors 710 to be fastened are provided on both sides thereof. The electrical connectors 710 are arranged in a line and have different structures to meet the requirements of connecting the inverter 700 with different electrical appliances.

[0039] In order to realize the automated tightening of the electrical connector 710, in this embodiment, a tightening device 300 is provided on both sides of the recessed part of the base 100. The tightening device 300 is movably arranged in the processing area, and includes a tightening assembly 310 for tightening the electrical connector 710, which can be flexibly adjusted according to the position of the electrical connector 710 to ensure that each electrical connector 710 can be accurately tightened. The tightening assembly 310 is provided with a card connector 311 adapted to the electrical connector 710, which can ensure that the electrical connector 710 can be firmly fixed during the rotation process, reducing product quality problems caused by inaccurate tightening and improving the accuracy of the automated tightening of the electrical connector 710.

[0040] In this embodiment, the tightening assembly 310 includes a first drive structure 312 that is detachably connected to the card connector 311 and drives the card connector 311 to rotate. The first drive structure 312 is in communication with the detection assembly 400 and adjusts the position and angle of the card connector 311 based on the detection signal to match the posture of the card connector 311 with the posture of the electrical connector 710. On the one hand, intelligent adjustment of the posture of the card connector 311 is achieved, improving the flexibility and accuracy of the tightening process. On the other hand, the card connector 311 can be driven to rotate the electrical connector 710 to achieve tightening of the electrical connector 710.

[0041] In this embodiment, the electrical connector 710 is provided with a first connecting portion 711, and the card connector 311 has a second connecting portion 313 that forms a concave-convex fit with the first connecting portion 711. When the posture of the card connector 311 is adapted and aligned with the posture of the electrical connector 710, and the second connecting portion 313 moves toward the first connecting portion 711, the first connecting portion 711 can be inserted into the second connecting portion 313. The concave-convex fit design ensures a stable connection between the electrical connector 710 and the card connector 311. The posture adjustment design enables the first connecting portion 711 to be smoothly inserted into the second connecting portion 313 under the drive of the second driving structure 320 when the second connecting portion 313 moves to the front of the first connecting portion 711 (i.e., when the card connector 311 is aligned with the electrical connector 710), thereby effectively improving the smoothness and reliability of the fastening process.

[0042] Preferably, in this embodiment, the first connection portion 711 is a protrusion of an irregular shape, and the second connection portion 313 is a groove adapted to the protrusion.

[0043] In this embodiment, the tightening assembly 310 includes a first mounting base 314 detachably connected to a third drive structure 330 and arranged perpendicular to the product rack 200. The first drive structure 312 is detachably mounted on the end of the first mounting base 314 facing away from the product rack 200. The first mounting base 314 is also provided with a rotating shaft 315, one end of which is connected to the output end of the first drive structure 312 and the other end is connected to the clamping joint 311. This ensures smooth rotation of the clamping joint 311, further ensuring stability during the tightening process. This detachable connection design also facilitates maintenance and replacement of the device.

[0044] In this embodiment, the first driving structure 312 includes a rotating motor, which is connected to the rotating shaft 315 through a coupling, effectively improving the transmission efficiency and reliability, reducing vibration, and extending the service life of the equipment.

[0045] Preferably, in this embodiment, two sets of tightening assemblies 310 are provided, each set having a different structure of the clamping connectors 311, with a gap between the two sets of tightening assemblies 310. These two different sets of clamping connectors 311 can handle different types of electrical connectors 710, effectively increasing the flexibility of the device. Furthermore, the gap between the two sets of tightening assemblies 310 prevents interference, improving the compactness and efficiency of the entire system.

[0046] In this embodiment, the tightening assembly 310 is arranged perpendicularly to the product placement rack 200 in the processing area, and the centerline of the clamping joint 311 is aligned with the centerline of the electrical connector 710. The tightening device 300 includes a second drive structure 320 connected to the tightening assembly 310. The second drive structure 320 is used to drive the tightening assembly 310 to move vertically toward or away from the electrical connector 710 so that the first connecting portion 711 can be smoothly inserted into the second connecting portion 313. The positional layout of the tightening assembly 310 and the height design of the clamping joint 311 effectively simplify the movement path of the tightening assembly 310, reduce unnecessary movement distance, and thus improve tightening efficiency. The second drive structure 320 enables precise movement of the tightening assembly 310, ensuring the accuracy of the tightening process.

[0047] Preferably, in this embodiment, the second driving structure 320 is a linear sliding module arranged perpendicular to the first track 510 , and guide rails are provided on both sides of the linear sliding module to ensure smooth movement of the third driving structure 330 .

[0048] To facilitate tightening electrical connectors 710 at different locations, in this embodiment, the tightening device 300 further includes a third drive structure 330 movably disposed between the second drive structure 320 and the tightening assembly 310. The third drive structure 330 is vertically connected to the tightening assembly 310 and the second drive structure 320, respectively, and drives the tightening assembly 310 to move horizontally toward or away from the electrical connector 710. The third drive structure 330 provides precise horizontal adjustment capabilities, enhancing the adaptability and flexibility of the system, enabling sequential tightening of multiple electrical connectors 710 on the inverter 700, while also ensuring that the electrical connector 710 can be accurately tightened regardless of its location.

[0049] In this embodiment, the third drive structure 330 is a linear sliding module connected to the second drive structure 320 on one side and to the first mounting seat 314 on the other side. The linear sliding module extends in a direction parallel to the product placement rack 200 and extends to the two guide rails, forming a movable connection with the guide rails, further ensuring the smooth movement of the tightening assembly 310.

[0050] In this embodiment, a detection component 400 is also included which is detachably arranged in the loading area of the base 100. The detection component 400 is communicated with the tightening component 310 to detect the posture of the electrical connector 710 and form a detection signal to feed back to the tightening component 310, so that the tightening component 310 can automatically adjust its posture according to the posture of the electrical connector 710 to achieve precise docking with the electrical connector 710 of different postures, thereby saving the process of manually adjusting the electrical connector 710 and effectively improving the efficiency of assembling the electrical connector 710.

[0051] In this embodiment, the detection component 400 is provided with two groups and is arranged relative to each other, which includes a second mounting base 410 detachably provided on the base 100, and a detection sensor 420 detachably provided on the second mounting base 410. The detection sensor 420 forms a communication connection with the first driving structure 312. Preferably, the detection sensor 420 is an image sensor, which effectively ensures the accurate transmission of data and improves the intelligence level of the fastening process.

[0052] In order to further ensure the accuracy of the fastening of the electrical connector 710 and the stability of the fastening process, in this embodiment, the base 100 is detachably provided with a clamping assembly 600 near one end of the processing area. The clamping assembly 600 includes a clamping member 610 movably provided above the processing area and a driving member 620 that drives the clamping member 610 to move vertically toward the product placement rack 200. The clamping member 610 is coaxial with the product placement rack 200 in the processing area. When the clamping member 610 moves toward the processing position close to the product placement rack 200, the clamping member 610 abuts against the surface of the inverter 700 and forms a limit for the longitudinal movement of the inverter 700. A rubber pad 611 is provided on the clamping member 610, which ensures the stability of the fixation of the inverter 700 while avoiding damage to the surface of the inverter 700.

[0053] Preferably, in this embodiment, the driving member 620 is a driving cylinder.

[0054] In order to further improve the working efficiency of the equipment, in this embodiment, the tightening device 300 is provided with two groups, which are symmetrically arranged on both sides of the driving device 500 and correspond to and are connected to the two groups of detection components 400 respectively.
