[0039] The driving mechanism includes a rack 17, a reduction motor 18, a motor mounting plate 19, a motor gear 20, a gear groove 21, a gear shaft 22, a gear 23 and a gear bracket 24. The rack 17 is arranged on one side of a slide rail 15. The top bolt of the motor mounting plate 19 is fixed to the reduction motor 18, and its bottom bolt is fixed to the mounting plate 4. The output shaft of the reduction motor 18 is penetrated through the mounting plate 4 toward the rack 17. The motor gear 20 is arranged on the output shaft of the reduction motor 18 and is meshed with the rack 17. The gear groove 21 is opened on the surface of the mounting plate 4 and is located on one side of the motor mounting plate 19. One side of the gear bracket 24 is bolted to the surface of the mounting plate 4 and is bent into the gear groove 21 toward the rack 17.

[0040] The reduction motor 18 can provide a stable speed and torque output, ensuring that the drive mechanism can still operate smoothly when the load changes. The meshing between the rack 17, the motor gear 20 and the gear 23 can achieve efficient transmission. The meshing between the rack 17, the motor gear 20 and the gear 23 enables the reduction motor 18 to provide a driving force to drive the motor gear 20 to rotate. Through the transmission of the gears, the slider 16 and the slide rail 15 can be driven to slide, and the mounting plate 4 can be further driven to slide to a specified position.

[0041] The flipping mechanism includes a material tray water receiving tray 25 arranged on the top of the accompanying tray bracket 5, two positioning material trays 26 are arranged on the material tray water receiving tray 25, and a positioning column 27 is arranged at the four corners of the two positioning material trays 26.

[0042] The water tray 25 can collect possible liquids to prevent liquid leakage from polluting the equipment and the environment; the design of the two positioning trays 26 provides support for the inverter housing, so that the inverter housing can be temporarily placed on the positioning trays 26 when flipping is required. The setting of the positioning columns 27 further enhances the stability of the positioning trays 26 and ensures the precise positioning of the inverter housing before and after flipping. The presence of the support base plate 28 provides solid support for the flipping fixing plate 29. The design of the flipping fixing plate 29 enables the inverter housing to remain stable during the flipping process. The design of the pad 30 can provide uniform support for the inverter housing. The presence of the fixing mechanism ensures that the inverter housing is firmly fixed during the flipping process.

[0043] The fixing mechanism includes a cylinder fixing seat 31, a flip driving cylinder 32, a flip connecting rod seat 33, a flip movable connecting rod 34 and a flip fixed pressure block 35. The cylinder fixing seat 31 is arranged on one side of the mounting plate 4, which is located on the side away from the cushion block 30. The bottom bolt of the flip driving cylinder 32 is fixed to the cylinder fixing seat 31, and its top bolt is fixed to the flip connecting rod seat 33. The flip connecting rod seat 33 is arranged on the side facing the cushion block 30. The specific number of the flip movable connecting rods 34 is two.

One side of the flip fixed pressure block 35 is rotatably connected to the piston rod of the flip driving cylinder 32.

[0044] The cylinder fixing seat 31 provides a solid support for the driving cylinder, ensuring the stability and accuracy of the cylinder during operation. The driving cylinder can generate sufficient thrust or pulling force through the telescopic movement of the piston rod to achieve a firm fixation of the inverter housing; the flip connecting rod seat 33 is a key component connecting the driving cylinder and the movable connecting rod, ensuring stable transmission between the two; one side of the flip fixed pressure block 35 is rotationally connected to the piston rod of the flip driving cylinder 32. This design enables the pressure block to move with the telescopic movement of the piston rod, thereby achieving the fixation and release of the inverter housing.

[0045] The mechanical gripper connection mechanism includes a flange connection plate 36 arranged at the end of the multi-axis mechanical arm 6, a transition short plate 37 is arranged on the flange connection plate 36, and a transition long plate 38 is bolted to both sides of the transition short plate 37.

[0046] Through the combined design of the flange connecting plate 36, the transition short plate 37 and the transition long plate 38, the structure of the entire manipulator is more stable; the multi-axis robot arm 6 enables the manipulator to move flexibly in three-dimensional space to adapt to the inverter housing grasping requirements in different positions and directions.

[0047] The mechanical gripper mechanism includes a gripping fixing plate 39, a supporting pad 40 and a contact block 41. The bottom bolts of the gripping fixing plate 39 are fixed to the two transition long plates 38. The specific number of the supporting pads 40 is four, and they are arranged at the four corners of the gripping fixing plate 39. The specific number of the contact blocks 41 is four, and they are arranged on the top of the supporting pad 40. A group of movable clamping mechanisms for fixing the inverter housing are arranged on one side of the four contact blocks 41.

[0048] The hand-grip fixing plate 39 is fixed to the two transition long plates 38 by bolts, providing strong structural strength and stability. The four contact blocks 41 are evenly distributed on the top of the supporting pad 40, so that the inverter housing can be evenly and stably supported and clamped.

[0049] The movable clamping mechanism includes a clamping drive cylinder 42, a clamping connecting rod seat 43, a clamping movable connecting rod 44 and a clamping fixed pressure block 45. The clamping drive cylinder 42 is arranged on one side of the contact block 41, and its bottom bolt is connected to the surface of the hand-grabbing fixing plate 39. The clamping connecting rod seat 43 is arranged on one side of the opposite contact block 41, and the bottom bolt of the clamping connecting rod seat 43 is connected to the top of the clamping drive cylinder 42.

The bottoms of the two clamping movable connecting rods 44 are rotatably connected to the two sides of the clamping connecting rod seat 43, and the tops are rotatably connected to the clamping fixed pressure block 45. The clamping fixed pressure block 45 opens to one side of the piston rod of the clamping drive cylinder 42, and is rotatably connected to the piston rod of the clamping drive cylinder 42.

[0050] During the clamping process of the manipulator, the piston rod of the clamping drive cylinder 42 is extended and retracted to drive the fixed pressure block to rotate, the clamping connecting rod seat 43 plays a supporting role, and the clamping movable connecting rod 44 plays a connecting and rotating role. After the inverter housing and the contact block 41 are plugged in, the clamping fixed pressure block 45 can fix the inverter housing, realize accurate clamping and release of the inverter housing, and prevent it from falling off during transportation.

[0051] A plurality of floor rail water receiving trays 46 are arranged on both sides of the floor rail 3, and the floor rail water receiving trays 46 are arranged between the machining center 1 and the floor rail 3; the floor rail water receiving trays 46 arranged on both sides can collect the liquid dripping during the production process, making the entire production environment neater.

[0052] Working principle: first use the contact block 41 on the multi-axis robot 6 to plug into the inverter housing, and then use the clamping drive cylinder 42 to drive the clamping fixed pressure block 45 to fix the inverter housing. In this way, the inverter housing can be taken from the upper bin 2, and then the reduction motor 18, rack 17, motor gear 20, gear 23 and slider 16 and other components are used to drive the mounting plate 4 to slide. When it slides to the specified position, the multi-axis robot 6 is placed in the corresponding machining center 1 for processing. When the inverter housing needs to be flipped, the housing to be flipped is placed from the positioning tray 26 to the flip fixing plate 29 On the top, first connect it with the shell through the pad 30 on the flip fixing plate 29, and then fix the shell accordingly through the flip driving cylinder 32, flip connecting seat, flip movable connecting rod 34 and flip fixed pressing block 35 and other components. When the robot arm rotates to the other side, the inverter shell is released, and the robot arm grabs the workpiece from the other side, thereby changing the direction, and then puts it into the corresponding machining center 1 for processing. After all the processing steps are completed, it slides to the designated position and is placed on the unloading conveyor belt 8. The conveyor belt is driven by the unloading motor 11, the unloading driving wheel 12 and the unloading chain 13 and other components to complete the unloading.
