The variable distance gripper 424 can be a suction cup type gripper, for example, the variable distance gripper 424 has a plurality of suction nozzles, which can be provided with four, six, etc., a plurality of suction nozzles are connected to an external air suction device (not shown) to generate negative pressure in the suction nozzles and thereby adsorb the material 200, the number of variable distance grippers 424 can be two, four, six, etc., and the number of variable distance grippers 424 corresponds to the number of sliding members 423 and is connected one-to-one. The variable distance driving member 425 can be a driving device such as a pneumatic cylinder, which can drive the variable distance plate 422 to move along the Y-axis direction, when the variable distance plate 422 moves, the corresponding guide column 4231 is guided by the inclined groove 4221 to move along the X-axis direction, the guide column 4231 drives the corresponding sliding member 423 to move along the X-axis direction, and then drives the corresponding variable distance gripper 424 to move along the X-axis direction, to change the distance between adjacent variable distance grippers 424.

[0029] The material moving mechanism 40 is used to move the material 200 in the feeding mechanism 10 to the transfer positioning mechanism 30 for positioning, and to move the positioned material 200 to the carrier 21 in the carrier mechanism 20.

[0030] It can be understood that in the present embodiment, the feeding mechanism 10 stores the material 200 to be cleaned, and the material 200 to be cleaned is transferred to the transfer positioning mechanism 30 for positioning by the material moving mechanism 40, and the positioned material 200 is loaded into the carrier 21, which can be placed in an external cleaning device (not shown) to clean the material 200.

[0031] The loading device 100 provided by the embodiment of the present application can store and supply the material 200 through the feeding mechanism 10, take out the material 200 in the feeding mechanism 10 through the material moving mechanism 40, change the distance of a plurality of materials 200 through the cooperation of the distance changing assembly 42 and the distance changing gripper 424, and place the material 200 after the distance changing in the transfer positioning mechanism 30. The transfer positioning mechanism 30 positions the material 200, and then the material moving mechanism 40 transfers the material 200 after the positioning to the loading piece 21 in the loading mechanism 20, so as to complete the process of automatic transfer, distance changing and loading of the material 200, improve the degree of automation and the loading efficiency, and reduce the labor intensity of the workers.

[0032] In some embodiments, referring to Figure 2 and Figure 3 each chute 4221 includes opposite first and second ends 4221a and 4221b, the first ends 4221a of the plurality of chutes 4221 are equidistantly arranged, the second ends 4221b of the plurality of chutes 4221 are equidistantly arranged, and the distance between the first ends 4221a of two adjacent chutes 4221 is less than the distance between the second ends 4221b of the two adjacent chutes 4221. The equidistant arrangement of the first ends 4221a of the plurality of chutes 4221 and the equidistant arrangement of the second ends 4221b of the plurality of chutes 4221 can make the distance between the plurality of distance changing grippers 424 equal when the plurality of guide columns 4231 are located at the first ends 4221a of the corresponding chutes 4221 or at the second ends 4221b of the corresponding chutes 4221, thereby facilitating material taking and material placing. The distance between the first ends 4221a of two adjacent chutes 4221 is less than the distance between the second ends 4221b of the two adjacent chutes 4221, so that the distance between the plurality of distance changing grippers 424 when the plurality of guide columns 4231 are located at the first ends 4221a of the corresponding chutes 4221 is less than the distance between the plurality of distance changing grippers 424 when the plurality of guide columns 4231 are located at the second ends 4221b of the corresponding chutes 4221. In this way, when the distance changing plate 422 moves along the Y-axis direction, the distance between the adjacent distance changing grippers 424 can be changed.

[0033] In some embodiments, referring to Figure 2 and Figure 3 the distance changing assembly 42 further includes a first sliding rail 426 connected to one side of the connecting plate 421 facing the sliding member 423 and extending along the X-axis direction, each sliding member 423 is provided with a first sliding block 4232 on one side facing the first sliding rail 426, and each first sliding block 4232 is slidingly connected to the first sliding rail 426. Through the cooperation of the first sliding block 4232 and the first sliding rail 426, accurate guidance can be provided for the movement of the sliding member 423 along the X-axis direction, and the connection stability between the sliding member 423 and the connecting plate 421 is improved.

[0034] In the present embodiment, please refer to Figure 2 and Figure 3 The first slide rail 426 is provided with two, two first slide rails 426 are spaced apart along the Y-axis direction, and each first slide block 4232 on the sliding member 423 is provided with two, two first slide blocks 4232 are respectively connected to the two first slide rails 426. In this way, the accuracy of the movement of the sliding member 423 in the X-axis direction can be further improved, and the connection stability between the sliding member 423 and the connecting plate 421 can be improved.

[0035] In some embodiments, please refer to Figure 2 and Figure 3 The variable distance assembly 42 further comprises two second slide rails 427 each extending along the Y-axis direction, and the two second slide rails 427 are respectively arranged at the two ends of the side of the connecting plate 421 facing the variable distance plate 422. The variable distance plate 422 is provided with two second slide blocks 4222 on the side facing the second slide rails 427, and the two second slide blocks 4222 are respectively connected to the two second slide rails 427. Through the cooperation of the second slide block 4222 and the second slide rail 427, accurate guidance can be provided for the movement of the variable distance plate 422 in the Y-axis direction, and the two second slide rails 427 are respectively arranged at the two ends of the connecting plate 421 to provide balanced support for the variable distance plate 422.

[0036] In some embodiments, please refer to Figure 2 and Figure 3 Each second slide rail 427 is provided with a bumper 428 at both ends along the Y-axis direction, and each bumper 428 is connected to the connecting plate 421 and arranged towards the second slide block 4222. During the movement of the variable distance plate 422, especially during starting, stopping or rapid variable distance, the second slide block 4222 may generate a large impact force on both ends of the second slide rail 427 due to inertia. The bumper 428 can effectively absorb these impact forces. In addition, the bumper 428 also plays a role in limiting the movement range of the second slide block 4222, ensuring that the second slide block 4222 does not disengage from the second slide rail 427 due to excessive displacement.

[0037] In some embodiments, please refer to Figure 2 and Figure 3Each guide column 4231 is provided with a roller 4233 at one end of the chute 4221, the roller 4233 rotates against the side wall of the chute 4221, and the diameter of the roller 4233 is smaller than the width of the chute 4221. By setting the roller 4233, the sliding friction between the guide column 4231 and the side wall of the chute 4221 can be changed into the rolling friction between the roller 4233 and the side wall of the chute 4221, reducing the friction, and further improving the movement speed of the variable distance assembly 42, so that the variable distance assembly 42 can more efficiently adjust the distance between the plurality of variable distance grippers 424, and improve the efficiency of material 200 grabbing and transferring.

[0038] In some embodiments, referring to Figure 1 , Figure 2 and Figure 3 , the sliding member 423 extends out of the connecting plate 421 along the Y-axis direction, and one end of the sliding member 423 extending out of the connecting plate 421 is connected to the middle part of the variable distance gripper 424. When the variable distance gripper 424 grabs the material 200, the weight of the material 200 will generate a force on the variable distance gripper 424, and the middle part of the variable distance gripper 424 connected to the sliding member 423, so that the gripper is more uniform when bearing the weight of the material 200.

[0039] In some embodiments, referring to Figure 1 and Figure 2 , the feeding mechanism 10 includes a material loading bin 11 and a material tray 12, the material tray 12 is arranged in the material loading bin 11, the material tray 12 is used to carry the material 200, and the material transfer mechanism 40 is used to transfer the material 200 in the material tray 12 to the transfer positioning mechanism 30. The material loading bin 11 can be provided with a lifting mechanism (not shown in the figure), such as a lifting cylinder and a cooperating structure of a material loading plate, so that a plurality of material trays 12 can be stacked on the lifting mechanism. When the material 200 in the uppermost material tray 12 is taken out, the empty material tray 12 can be taken out by manual or other mechanical hand moving device, the lifting mechanism lifts the material tray 12 loaded with the material 200, and the material transfer mechanism 40 takes the material, so as to further provide the degree of automation.

[0040] In some embodiments, referring to Figure 1 and Figure 2The loading device 100 further comprises a loading mechanism 50 arranged adjacent to the material carrying mechanism 20 and the intermediate positioning mechanism 30, the loading mechanism 50 comprising a loading driving member 51 and a loading gripper 52 connected to the loading driving member 51, the loading driving member 51 driving the loading gripper 52 to move so as to transfer the material 200 on the intermediate positioning mechanism 30 to the material carrying member 21. The loading driving member 51 can be a driving device such as a mechanical arm, and the loading gripper 52 can be a structure of a cylinder cooperating with a clamping finger. By arranging the loading mechanism 50, the work of transferring the material 200 on the intermediate positioning mechanism 30 to the material carrying member 21 can be completed, and the work efficiency is improved. It can be understood that in the embodiment, the distance between the plurality of materials 200 positioned by the intermediate positioning mechanism 30 can be kept consistent with the distance between the plurality of materials 200 carried by the material carrying member 21, so that the transfer of the material 200 between the intermediate positioning mechanism 30 and the material carrying member 21 can be completed by the clamping type loading gripper 52, the manufacturing cost of the loading gripper 52 is reduced, and the work efficiency is improved.

[0041] In some embodiments, referring to Figure 1 and Figure 2 The intermediate positioning mechanism 30 comprises a moving driving member 31 and a plurality of positioning members 32, one end of the moving driving member 31 is arranged adjacent to the material moving mechanism 40, and the other end is arranged adjacent to the loading mechanism 50, the plurality of positioning members 32 are all connected to the moving driving member 31, each positioning member 32 can carry and position the material 200, and the moving driving member 31 drives the plurality of positioning members 32 to move between the material moving mechanism 40 and the loading mechanism 50. The moving driving member 31 can be a driving device such as a linear module, and the plurality of positioning members 32 move synchronously, that is, the distance between adjacent positioning members 32 remains unchanged. The material moving mechanism 40 takes out the plurality of materials 200 from the tray 12 and adjusts the distance between the plurality of materials 200, and then places the plurality of materials 200 after the distance adjustment on the corresponding plurality of positioning members 32. The moving driving member 31 drives the plurality of positioning members 32 to move towards the loading mechanism 50, and the loading mechanism 50 transfers the materials 200 on the plurality of positioning members 32 to the material carrying member 21, so that the work speed of the loading device 100 can be improved.

[0042] The working process of the loading device 100 provided by the embodiment of the application is as follows:

[0043] Firstly, the material moving driving member 41 of the material moving mechanism 40 drives the distance adjustment assembly 42 to move to the material supply mechanism 10, so that the plurality of distance adjustment grippers 424 in the distance adjustment assembly 42 can grab the plurality of materials 200 in the tray 12, and then the material moving driving member 41 drives the distance adjustment assembly 42 to move towards the intermediate positioning mechanism 30, and the distance adjustment assembly 42 adjusts the distance between the plurality of materials 200 during the movement.

[0044] When the distance is changed, the distance changing driving member 425 drives the distance changing plate 422 to move along the Y-axis direction, the distance changing plate 422 drives the sliding member 423 to move along the X-axis direction through the cooperation of the inclined slot 4221 and the guide column 4231, the plurality of sliding members 423 drive the plurality of distance changing grippers 424 to move away from each other or move close to each other, thereby changing the distance between the adjacent materials 200 gripped by the distance changing grippers 424. In actual operation, whether the distance changing assembly 42 increases or decreases the distance between the adjacent materials 200 depends on the actual operation conditions. For example, if the distance between the adjacent materials 200 in the tray 12 is greater than the distance between the adjacent materials 200 in the material carrying member 21, the distance changing assembly 42 decreases the distance between the adjacent materials 200 after taking the materials 200 out of the tray 12; if the distance between the adjacent materials 200 in the tray 12 is less than the distance between the adjacent materials 200 in the material carrying member 21, the distance changing assembly 42 increases the distance between the adjacent materials 200 after taking the materials 200 out of the tray 12.

[0045] Then, the material moving mechanism 40 places the distance-changed materials 200 on the corresponding positioning members 32 of the transfer positioning mechanism 30, the moving driving member 31 drives the plurality of positioning members 32 to move towards the material loading mechanism 50, and the material loading mechanism 50 transfers the materials 200 on the plurality of positioning members 32 to the material carrying member 21.

[0046] In another embodiment, the material carrying member 21 carries the materials 200, the material loading mechanism 50 takes out the plurality of materials 200 from the material carrying member 21 and places the plurality of materials 200 on the corresponding positioning members 32, the moving driving member 31 drives the plurality of positioning members 32 to move towards the material moving mechanism 40, the material moving mechanism 40 takes off the materials 200 on the plurality of positioning members 32 and changes the distance, and then places the distance-changed materials 200 in the tray 12 of the material feeding mechanism 10.
