[0005] As a further improvement of the utility model, a flip push block is hinged on the clamping drive member, and a flip fixed block corresponding to the flip push block is provided on the flip frame. When the lifting drive member drives the clamping drive member to rise, the flip fixed block presses the flip push block to rotate so that the flip push block pushes the workpiece between the two clamping jaws to flip, and a reset elastic member is connected between the flip push block and the clamping drive member.

[0006] As a further improvement of the utility model, a flip push block is hinged on the clamping drive member, and a first driving member that can push the flip push block to flip downward is provided on the flipping frame, so that when the flip push block flips downward, it pushes the workpiece between the two clamping jaws to flip, and a reset elastic member is connected between the flip push block and the clamping drive member.

[0013] Figure 1 It is a structural schematic diagram of the utility model;

[0014] Figure 2 yes Figure 1 Schematic diagram of the structure from another angle. DETAILED DESCRIPTION

[0015] The technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0016] Reference Figure 1-2 The utility model proposes a workpiece flipping device for a weighing sensor production line, comprising a conveying frame 1, a conveyor belt 11 arranged on the conveying frame 1 for driving the workpiece to move forward and backward, and a flipping frame 2 fixed relatively to the conveying frame 1. The flipping frame 2 is provided with two clamping jaws 3, a clamping driving member 4 capable of driving the two clamping jaws 3 to move to achieve loosening or clamping, and a lifting driving member 5 capable of driving the clamping driving member 4 to move up and down so that the two clamping jaws 3 can move downward to clamp the workpiece on the conveyor belt 11.

[0017] Reference Figure 1 Obviously, first assume Figure 1 The workpiece moves forward from right to left, and moves backward from right to left. Assuming that the workpiece is moving forward at this time, during the movement of the conveyor belt 11, the clamp 3 moves downward to clamp the front end of the workpiece and moves upward. It should be noted that the conveyor belt 11 keeps transmitting forward and the rear end of the workpiece contacts the conveyor belt 11 so that the rear end moves forward. When the rear end is in front of the front end, the clamp 3 moves downward again to put down the workpiece to achieve flipping.

[0018] As a further improvement of the utility model, a flip push block 41 is hinged on the clamping drive member 4, and a flip fixed block 21 corresponding to the flip push block 41 is provided on the flip frame 2. When the lifting drive member 5 drives the clamping drive member 4 to rise, the flip fixed block 21 presses the flip push block 41 to rotate so that the flip push block 41 pushes the workpiece between the two clamping jaws 3 to flip, and a reset elastic member 42 is connected between the flip push block 41 and the clamping drive member 4.

[0019] When the clamped workpiece rises and leaves the conveyor belt 11, the workpiece can be flipped by setting the flip push block 41, which is very convenient and quick; and the setting of the flip fixed block 21 makes it unnecessary to set up an additional driving component to drive the flip push block 41 to flip, and the flip push block 41 can be flipped during the rising process of the clamp 3.

[0020] As a further improvement of the utility model, a flip push block 41 is hinged on the clamping drive member 4, and a first driving member that can push the flip push block 41 to flip downward is provided on the flip frame 2, so that when the flip push block 41 flips downward, it pushes the workpiece between the two clamping jaws 3 to flip, and a reset elastic member 42 is connected between the flip push block 41 and the clamping drive member 4.

[0021] As a further improvement of the present invention, the flip push block 41 is L-shaped. The L-shaped setting can easily drive the flip push block 41 to flip by flipping the fixed block 21 or the first driving member, thereby increasing the contact area of ​​the transmission and improving stability.

[0022] As a further improvement of the present utility model, a limit detection piece 51 is provided on the lifting drive member 5, and a photoelectric sensor 52 for the limit detection piece 51 to be inserted is provided on the turning frame 2.

[0023] As a further improvement of the present invention, the two clamping jaws 3 are provided with clamping bosses 31 on the surfaces of the opposite sides.

[0024] As a further improvement of the present invention, the clamping boss 31 is in a truncated cone shape.

[0025] As a further improvement of the present invention, the turning frame 2 is provided with limiting bosses 22 on both upper and lower sides of the lifting drive member 5 .
