[0076] The embodiment of the present application also makes the following optimization:

[0077] 1) When the full-automatic turnover device is turned over, it can achieve better turnover for ordinary plunger pumps or boxes, and the turnover torque is larger for heavy plunger pumps, so that each servo motor needs a servo motor with a larger rated torque, and a reducer is arranged at the output end of the servo motor to effectively increase the turnover torque, and considering the installation space, it is appropriate to arrange a larger torque right-angle reducer.

[0078] 2) In order to effectively complete the grabbing of the plunger pump or the box, the first profiled jaw 312 and the second profiled jaw 315 need to have a larger static friction force, and the grabbing surface cannot have a large normal pressure, which requires that the grabbing surface has a larger friction coefficient, so that the grabbing surface of the first profiled jaw 312 and the second profiled jaw 315 needs to be sandblasted.

[0079] The turnover device ( Figure 2 ) is mainly used for turnover in the assembly process of the peripheral and internal components of the plunger pump, the left side of the turnover device ( Figure 2 ) is connected with the manual assembly station A, the right side is connected with the manual assembly station B, the turnover device ( Figure 2 ) is used in cooperation with the left and right manual assembly stations A and B, according to the model of the plunger pump and the assembly process parameters of the components, the whole turnover process is completed without human intervention, automatic turnover is realized, and the turnover process of the plunger pump is as follows:

[0080] (1) The plunger pump is hoisted and placed on the pallet at the manual assembly station A by a hoisting equipment. The model and serial number of the plunger pump are confirmed by scanning the code with a handheld barcode scanner (the main components of the plunger pump are engraved with QR code information).

[0081] (2) At the manual assembly station A, some of the internal and external components of the plunger pump are assembled. After the assembly is completed, press the start button of the double speed sprocket at the assembly station A. The double speed chain drives the tray containing the plunger pump into the fully automatic flipping station.

[0082] (3) The tray equipped with the plunger pump arrives at the tipping device. Figure 2 After the flipping station is completed, the double-speed sprocket stops rotating.

[0083] (4) Installed on the tilting device ( Figure 2 After the photoelectric sensor on the device detects the plunger pump, it sends a feedback to the control system. The control system then issues a command to start the lifting cylinder 415, which drives the lifting plate 411. Guided by the guide column 407, the lifting column 413 and the second guide column 412 are inserted into the lifting hole and guide hole of the tray, respectively. Under the guidance of the second guide column 412, the plunger pump and the tray are lifted together. When the lifting is in place, the sensor sends a feedback to the control system. Upon receiving the feedback, the control system issues a command to start the horizontal cylinder 410, which drives the support plate 414 into the bottom of the lifting frame 411 to support the tray and tooling plate. This prevents the lifting cylinder 415 from retracting under its own weight when the lifting cylinder 415 is under low pressure, which would affect the gripping position of the first and second profile grippers 312.

[0084] (5) After the control system receives the signal that the lifting position is in place, it issues a command and the third servo motor 301 starts, so that the first copying gripper 312 and the second copying gripper 315 are reset and enter the 0° gripper gripping position. The second servo motor 314 starts, drives the forward and reverse trapezoidal screw 310, and drives the flipping frame 302 to reset and enter the 0° gripper holding position.

[0085] (6) After the control system receives the 0° gripping reset signal from the gripper, the first servo motor 209 starts, drives the connecting rod 211, the first universal joint 210, and the second universal joint 212, drives the lifting machine 206, thereby driving the entire flipping mechanism 3 to reset.

[0086] (7) After the lifting mechanism 2 and the flipping mechanism 3 have completed their reset and entered the gripping position, the control system receives a command from the servo motor. The lifting mechanism 2 drives the flipping mechanism 3 to descend to the gripping height of 0° under the action of the first servo motor 209, so that the first copying gripper 312 and the second copying gripper 315 enter the gripping position.

[0087] (8) Control system receives feedback from the first servo motor 209, the second servo motor 314 starts, drives two turnover frame 302 and the first profiled jaw 312 and the second profiled jaw 315 to move oppositely, when the first profiled jaw 312 and the second profiled jaw 315 move to 0° lifting position, stop, the plunger pump is reliably clamped.

[0088] (9) Control system receives feedback from the second servo motor 314, the first servo motor 209 starts, drives the whole turnover mechanism 3 to clamp the plunger pump to rise to 0° turnover position and stop.

[0089] (10) Control system receives feedback from the first servo motor 209, the third servo motor 301 starts, drives the first profiled jaw 312 and the second profiled jaw 315 to clamp the plunger pump to rotate from 0° position to 90° position and stop.

[0090] (11) Control system receives feedback from the third servo motor 301 after the turnover is completed, the first servo motor 209 drives the lifting mechanism 2 to descend to the lifting initial position and stop.

[0091] (12) Control system receives feedback from the third servo motor 301 and the first servo motor 209 after the turnover is completed, the second servo motor 314 starts, drives the lead screw 310 to drive two turnover frames 302 to move oppositely, the turnover mechanism 3 returns to the clamping initial position and stop.

[0092] (13) Control system receives feedback from the second servo motor 314, the first servo motor 209, the third servo motor 301 and the second servo motor 314 start, drive the whole turnover device to return to the initial position of the device and stop, the horizontal cylinder 410 drives the support plate 414 to return to the initial position, the jacking cylinder 415 drives the jacking plate 411 to return to the initial position, the tray with the plunger pump is seated on the speed chain wheel, under the action of the control system, the speed chain wheel reverses, the tray with the plunger pump is transported to the manual assembly station A for assembly.

[0093] (14) After the manual assembly station A is completed, press the start button of the manual assembly station A, the tray with the plunger pump is transported to the turnover station and repeats 3-13, and is turned over from 90° position to 180° position, after the turnover is completed, it is automatically transported to the manual assembly station A for installation of components.
