[0053] In order to make the technical problems, technical solutions and beneficial effects solved by the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0054] As Figures 1 to 7 shown, the handling mechanism 10 provided by the embodiment of the present utility model includes a vehicle body 1 and a conveyor assembly 2. A plurality of material platforms 11 are arranged on the vehicle body 1, and the material platforms 11 are used to carry the parts 20 to be handled.

[0055] At least one material platform 11 is provided with a conveyor assembly 2, and the conveyor assembly 2 is used to convey the part 20 to be handled on the material platform 11 where it is located out of the vehicle body 1 along the first direction x, and / or to convey the part 20 to be handled from outside the vehicle body 1 to the material platform 11 where it is located along the first direction x.

[0056] The handling mechanism 10 provided by the embodiment of the present utility model is provided with a plurality of material platforms 11 on the vehicle body 1 for carrying the workpieces 20 to be handled, so that the handling mechanism 10 can handle a plurality of workpieces 20 to be handled simultaneously. In addition, the handling mechanism 10 is provided with a conveying assembly 2 on at least one material platform 11, and the conveying assembly 2 is used to realize the sending out (conveying the workpiece 20 from the material platform 11 where it is located to outside the vehicle body 1) and / or recycling (conveying the workpiece 20 from outside the vehicle body 1 to the material platform 11 where it is located) of the workpiece 20 to reduce the handling time.

[0057] Among them, "a plurality" means two or more.

[0058] In one embodiment, as Figure 1 and Figure 2 shown, there are two material platforms 11, and a conveying assembly 2 is correspondingly arranged on each material platform 11.

[0059] The conveying assembly 2 on one of the material platforms 11 is used to convey the workpiece 20 on the material platform 11 where it is located to outside the vehicle body 1 along the first direction x, and the conveying assembly 2 on the other material platform 11 is used to convey the workpiece 20 from outside the vehicle body 1 to the material platform 11 where it is located along the first direction x.

[0060] When the handling mechanism 10 moves to a specified position (the specified position can be the loading platform of the following testing mechanism 30), the workpiece 20 on the material platform 11 where it is located is conveyed to the specified position through the conveying assembly 2 on one of the material platforms 11 to realize feeding. Or, the workpiece 20 at the specified position can be conveyed to the material platform 11 where it is located through the conveying assembly 2 on the other material platform 11 to realize the recycling of the workpiece 20 to reduce the handling time.

[0061] In one embodiment, as Figure 4 shown, the conveying assembly 2 includes a conveying driving member 21, a first conveyor belt 22, a first pulley 23 and a second pulley 24. The first pulley 23 and the second pulley 24 are arranged at intervals along the first direction x and are respectively rotatably connected to the vehicle body 1. The first conveyor belt 22 is wound around the first pulley 23 and the second pulley 24. The conveying driving member 21 is installed on the vehicle body 1 and is connected to the first pulley 23. The conveying driving member 21 is used to drive the first pulley 23 to rotate.

[0062] The first conveyor belt 22 is used to carry the workpiece 20 to be handled.

[0063] When the conveying driving member 21 drives the first pulley 23 to rotate, the first conveyor belt 22 can be driven to move, so that the workpiece 20 carried on the first conveyor belt 22 moves to realize the transportation of the workpiece 20 to be handled.

[0064] In one embodiment, as Figure 4As shown, the conveying assembly 2 further includes a linkage rod 25, a second conveyor belt 26, a third pulley 28 and a fourth pulley 29. The third pulley 28 and the fourth pulley 29 are arranged at intervals along the first direction x and are rotatably connected to the vehicle body 1. The second conveyor belt 26 is wound around the third pulley 28 and the fourth pulley 29.

[0066] The second conveyor belt 26 is used to carry the objects 20 to be transported.

[0067] When the conveying driving member 21 drives the first pulley 23 to rotate, the first pulley 23 will simultaneously drive the third pulley 28 to rotate synchronously through the linkage rod 25, thereby driving the second conveyor belt 26 to move. Since the linkage rod 25 is coaxially connected to the first pulley 23 and the third pulley 28, the first conveyor belt 22 will move synchronously with the second conveyor belt 26, so that the objects 20 to be transported carried on the first conveyor belt 22 and the second conveyor belt 26 move, thereby realizing the transportation of the objects 20 to be transported.

The reduction member 27 is used to make the rotation speed of the first pulley 23 lower than the rotation speed of the output shaft of the driving motor, so as to avoid the first pulley 23 rotating too fast, resulting in the transportation speed of the transported object 20 being difficult to control.

[0070] In one embodiment, the deceleration member 27 includes a first deceleration wheel 271 , a second deceleration wheel 272 and a deceleration belt 273 . The first deceleration wheel 271 and the second deceleration wheel 272 are rotatably connected to the vehicle body 1 , respectively, and the deceleration belt 273 is wound around the first deceleration wheel 271 and the second deceleration wheel 272 .
