[0095] 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.

[0096] As Figures 1 to 14 shown, the loading and unloading device provided by the embodiment of the present utility model includes a loading mechanism 3, an unloading mechanism 4, a handling mechanism 1 and a material loading mechanism 2. The material loading mechanism 2 is used to carry the material 5. The handling mechanism 1 includes a vehicle body 11 and a conveying component 12. A material platform 111 is arranged on the vehicle body 11, and the material platform 111 is used to carry the material loading mechanism 2.

[0097] A conveying component 12 is arranged on the material platform 111. The conveying component 12 is used to convey the material loading mechanism 2 on the material platform 111 where it is located to the loading mechanism 3 along the first direction x, or to convey the material loading mechanism 2 from the unloading mechanism 4 to the material platform 111 where it is located along the first direction x.

[0098] The loading mechanism 3 is used to take out the untested material 5 on the material loading mechanism 2 for testing; the unloading mechanism 4 is used to place the tested material 5 on the material loading mechanism 2.

[0099] In the loading and unloading device provided by the embodiment of the present utility model, a plurality of material platforms 111 for carrying the material loading mechanism 2 are arranged on the vehicle body 11, so that the handling mechanism 1 can carry a plurality of material loading mechanisms 2 at the same time. In addition, the handling mechanism 1 is provided with a conveying component 12 on at least one material platform 111. Through the conveying component 12, the sending out (conveying the material loading mechanism 2 on the material platform 111 where it is located to the loading mechanism 3 or the unloading mechanism 4) and / or recycling (conveying the material loading mechanism 2 from the loading mechanism 3 or the unloading mechanism 4 to the material platform 111 where it is located) of the material loading mechanism 2 are realized, reducing the handling time and the machine stop time.

[0100] In one embodiment, "a plurality of" means two or more.

[0101] In one embodiment, as Figure 2 and Figure 3 shown, there are two material platforms 111, and a conveying component 12 is correspondingly arranged on each material platform 111.

[0102] One of the conveying assemblies 12 on the loading platform 111 is used to convey the loading mechanism 2 on the loading platform 111 where it is located along the first direction x to outside the loading mechanism 3 or the unloading mechanism 4, and the conveying assembly 12 on the other loading platform 111 is used to convey the loading mechanism 2 along the first direction x from the loading mechanism 3 or the unloading mechanism 4 to the loading platform 111 where it is located.

[0103] When the handling mechanism 1 moves to the designated position (the designated position can be the loading platform of the following testing mechanism), the conveying assembly 12 on one of the loading platforms 111 conveys the loading mechanism 2 on the loading platform 111 where it is located to the designated position to achieve feeding. Alternatively, the conveying assembly 12 on the other loading platform 111 can convey the loading mechanism 2 at the designated position to the loading platform 111 where it is located to recycle the loading mechanism 2, which can reduce the handling time.

[0104] In one embodiment, as Figure 5 shown, the conveying assembly 12 includes a conveying driving member 121, a first conveyor belt 122, a first pulley 123, and a second pulley 124. The first pulley 123 and the second pulley 124 are arranged at intervals along the first direction x and are respectively rotatably connected to the vehicle body 11. The first conveyor belt 122 is wound around the first pulley 123 and the second pulley 124. The conveying driving member 121 is installed on the vehicle body 11 and is connected to the first pulley 123. The conveying driving member 121 is used to drive the first pulley 123 to rotate.

[0105] The first conveyor belt 122 is used to carry the loading mechanism 2.

[0106] When the conveying driving member 121 drives the first pulley 123 to rotate, it can drive the first conveyor belt 122 to move, so that the loading mechanism 2 carried on the first conveyor belt 122 moves to achieve the transportation of the loading mechanism 2.

[0107] In one embodiment, as Figure 5 shown, the conveying assembly 12 further includes a linkage rod 125, a second conveyor belt 126, a third pulley, and a fourth pulley. The third pulley and the fourth pulley are arranged at intervals along the first direction x and are respectively rotatably connected to the vehicle body 11. The second conveyor belt 126 is wound around the third pulley and the fourth pulley.

[0108] The first pulley 123 and the third pulley are arranged at intervals along the second direction y, the second pulley 124 and the fourth pulley are arranged at intervals along the second direction y, and both ends of the linkage rod 125 are coaxially connected to the first pulley 123 and the third pulley respectively. The second pulley 124 and the fourth pulley are coaxially arranged.

[0109] The second conveyor belt 126 is used to carry the loading mechanism 2.

[0110] When the conveying driving member 121 drives the first pulley 123 to rotate, the first pulley 123 will simultaneously drive the third pulley to rotate synchronously through the linkage rod 125, thereby driving the second conveyor belt 126 to move. Since the linkage rod 125 is coaxially connected with the first pulley 123 and the third pulley, the first conveyor belt 122 will move synchronously with the second conveyor belt 126, so that the material carrier 2 carried on the first conveyor belt 122 and the second conveyor belt 126 moves, thereby realizing the transportation of the material carrier 2.

[0111] In one embodiment, the first direction x intersects the second direction y.

[0112] In one embodiment, if Figure 5 As shown, the conveying drive member 121 is a driving motor, and the conveying assembly 12 also includes a reduction member 127, which is transmission-connected between the output shaft of the driving motor and the first pulley 123. The reduction member 127 is used to make the rotation speed of the first pulley 123 lower than the rotation speed of the output shaft of the driving motor, so as to avoid the transportation speed of the loading mechanism 2 being difficult to control due to the excessive rotation speed of the first pulley 123.

[0113] In one embodiment, the deceleration member 127 includes a first deceleration wheel, a second deceleration wheel and a deceleration belt. The first deceleration wheel and the second deceleration wheel are rotatably connected to the vehicle body 11 respectively, and the deceleration belt is wound around the first deceleration wheel and the second deceleration wheel.

[0114] The output shaft of the driving motor is coaxially connected to the first reduction wheel, and the second reduction wheel is coaxially connected to the first pulley 123 .

[0115] When the driving motor is working, the first reduction wheel rotates and drives the reduction belt to move, thereby driving the second reduction wheel and the first pulley 123 to rotate synchronously to achieve power transmission.

[0116] In one embodiment, if Figure 4 , Figure 6 and Figure 7 As shown, the transport mechanism 1 further includes a material pressing assembly 13. The material pressing assembly 13 is provided on at least one material platform 111, and the material pressing assembly 13 is used to temporarily fix the material loading mechanism 2 on the material platform 111 where it is located, so as to prevent the material loading mechanism 2 from falling when the transport mechanism 1 moves.

[0117] In one embodiment, if Figure 4 , Figure 6 and Figure 7 As shown, preferably, a pressing assembly 13 is correspondingly provided on each material platform 111 , so that the material loading mechanism 2 on each material platform 111 can be temporarily fixed to prevent the material loading mechanism 2 from falling.

[0118] In one embodiment, if Figure 6 and Figure 7As shown, the blanking component 13 includes a blanking driving part 131 and a blanking block 132. The blanking driving part 131 is installed on the vehicle body 11 and is connected to the blanking block 132.

[0119] The blanking driving part 131 is used to drive the blanking block 132 to approach or move away from the vehicle body 11 along the third direction z. When the blanking block 132 approaches the vehicle body 11, it can press the loading mechanism 2 against the material table 111 to temporarily fix the loading mechanism 2 on the material table 111 where the blanking component 13 is located.

[0120] In one embodiment, the first direction x, the second direction y, and the third direction z intersect pairwise.

[0121] In one embodiment, as Figure 6 and Figure 7 shown, the blanking component 13 further includes a guiding part 133. The guiding part 133 is installed on the vehicle body 11, and the blanking block 132 is slidably connected to the guiding part 133 along the third direction z. The guiding part 133 can provide sliding guidance for the blanking block 132 along the third direction z.

[0122] In one embodiment, as Figure 6 and Figure 7 shown, the guiding part 133 is a slide rail, and the slide rail is installed on the vehicle body 11 and extends along the third direction z.

The sensor 136 is installed on the vehicle body 11, and an induction space is provided on the sensor 136. The sensing part 135 is installed on the blanking block 132.

[0125] The blanking block 132 can drive the sensing part 135 to move back and forth along the third direction z, so that the sensing part 135 can approach or move away from the induction space. When the sensing part 135 approaches the induction space of the sensor 136, the blanking block 132 returns to the calibrated origin position.
