[0047] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0048] See also Figure 1 The present application provides a material moving device 100 for moving a workpiece to a preset position. The material moving device 100 includes a base 10, a driving assembly 20 connected to the base 10, two linkage members 30 arranged in parallel and respectively connected to the driving assembly 20 for rotation, and a material suction assembly 40 connected to the two linkage members 30 for rotation.

[0049] See also Figure 1 and Figure 2 The driving assembly 20 includes a driving member 21 connected to the base 10, a driving wheel 22 connected to the driving member 21, a driven wheel 23 arranged on the base 10 at a vertical interval with the driving wheel 22, and a belt 24 sleeved on the driving wheel 22 and the driven wheel 23. The driving member 21 is arranged on the base 10 and connected to the base 10, the driving wheel 22 is rotatably arranged on the base 10, one end of the driving wheel 22 is coaxially connected to the driving member 21, the other end of the driving wheel 22 is rotatably connected to one of the linkage members 30, the driven wheel 23 is arranged on the base 10 at a distance from the driving wheel 22 and is rotatably connected to the other linkage member 30, and the belt 24 is sleeved on the outer periphery of the driving wheel 22 and the driven wheel 23. Exemplarily, the driving member 21 can be a rotary motor.

[0050] In this way, when the driving member 21 drives the driving wheel 22 to rotate, the driving wheel 22 drives the driven wheel 23 to rotate synchronously through the belt 24, so that the two linkage members 30 are driven by the driving wheel 22 and the driven wheel 23 to rotate synchronously with the driving wheel 22 and the driven wheel 23 as the center, respectively, so that the driving component 20 can stably drive the two linkage members 30 to rotate synchronously.

[0051] The driving wheel 22 includes a rotating portion 221 coaxially connected to the driving member 21, two limiting portions 222 respectively connected to the rotating portion 221, a second rotating shaft 223 connected to the rotating portion 221, and a second bearing 224 sleeved on the second rotating shaft 223. In this embodiment, the rotating portion 221, the two limiting portions 222, the second rotating shaft 223 and the second bearing 224 are coaxially arranged. The rotating portion 221 is roughly cylindrical, and the rotating portion 221 is arranged between the linkage member 30 and the base 10 and connected to the driving member 21, and the belt 24 is sleeved on the rotating portion 221, and the driving member 21 drives the rotating portion 221 to rotate. The two limiting portions 222 are roughly disc-shaped and are respectively connected to the opposite sides of the rotating portion 221, and the two limiting portions 222 respectively abut against the two sides of the belt 24 along the axial direction parallel to the second rotating shaft 223. The second rotating shaft 223 is substantially cylindrical, one end of which is disposed on the side of the rotating portion 221 facing the linkage member 30 and connected to the rotating portion 221. The second rotating shaft 223 passes through the corresponding limiting portion 222 of the linkage member 30 and is disposed on the corresponding linkage member 30, so that the rotating portion 221 is rotatably connected to the linkage member 30. The second bearing 224 is embedded in the limiting portion 222 of the corresponding linkage member 30 and sleeved on the second rotating shaft 223. By way of example, the second bearing 224 may be a rolling bearing.

[0052] Thus, by providing the above-mentioned two limiting parts 222, the two limiting parts 222 can respectively abut against the two sides of the belt 24 sleeved on the rotating part 221, thereby limiting the position of the belt 24, preventing the belt 24 from being offset during movement, and ensuring that the belt 24 stably drives the driven wheel 23 to rotate synchronously under the drive of the driving wheel 22. In addition, by providing one end of the second rotating shaft 223 connected to the rotating part 221, and the other end of the second rotating shaft 223 passing through the limiting part 222 and being inserted into the linkage member 30, a rotating connection structure is formed between the rotating part 221 and the linkage member 30, thereby realizing that the rotating part 221 drives the linkage member 30 to rotate through the second rotating shaft 223. In addition, by sleeved the second bearing 224 on the second rotating shaft 223, direct contact between the second rotating shaft 223 and the limiting part 222 is avoided, thereby reducing the force applied by the rotating part 221 to the linkage member 30 through the second rotating shaft 223, thereby improving the driving stability of the driving assembly 20.

[0053] The driving wheel 22 further includes a plurality of tooth-shaped portions 225, which are evenly arranged on the outer peripheral side of the rotating portion 221 along the axial direction of the second rotating shaft 223. In this way, the plurality of tooth-shaped portions 225 are evenly arranged on the outer peripheral side of the rotating portion 221, so that the rotating portion 221 can contact the belt 24 through the tooth-shaped portions 225, thereby increasing the friction between the rotating portion 221 and the belt 24, preventing the friction between the rotating portion 221 and the belt 24 from being too small and causing the belt 24 to slip during movement, which is conducive to ensuring that the belt 24 stably drives the driven wheel 23 to rotate synchronously.

[0054] It can be understood that the structure of the driven wheel 23 is the same as that of the driving wheel 22, so the specific structure of the driven wheel 23 is not repeated here. The difference between the driven wheel 23 and the driving wheel 22 is that the rotating part 221 on the driven wheel 23 is rotatably arranged on the base 10 and abuts against the belt 24, and the rotating part 221 of the driven wheel 23 is rotatably connected to the corresponding linkage member 30 through the second rotating shaft 223 of the driven wheel 23.

[0055] See also Figure 1 and Figure 3 The two linkage members 30 are both roughly rod-shaped, have equal lengths and are arranged in parallel on the side of the driving assembly 20 away from the base 10, and one end of the two linkage members 30 is rotatably connected to the driving wheel 22 and the driven wheel 23 respectively.

[0056] In this way, by setting two linkage members 30 in parallel and respectively connecting with the corresponding driving wheel 22 and driven wheel 23, the two linkage members 30 can be driven by the driving wheel 22 and the driven wheel 23 to rotate synchronously and always be parallel to each other during the rotation process.

[0057] Please continue reading Figure 3 The suction component 40 includes a connecting member 41 rotatably connected to the two linkage members 30, and a suction member 42 connected to the connecting member 41. The connecting member 41 is rotatably connected to one end of the two linkage members 30 away from the driving member 21, so that the opposite ends of one linkage member 30 are rotatably connected to the driving wheel 22 and the connecting member 41, and the opposite ends of the other linkage member 30 are rotatably connected to the driven wheel 23 and the connecting member 41. The suction member 42 is connected to the connecting member 41 and absorbs the workpiece, and the two linkage members 30 drive the connecting member 41 to drive the workpiece absorbed on the suction member 42 to rotate synchronously, so as to move the workpiece to a preset position.

[0058] In this way, since the two linkage members 30 are of equal length and are arranged in parallel, and the two ends of the two linkage members 30 are rotatably connected to the corresponding rotating parts 221 and the connecting member 41 respectively, the spacing between the ends of the two linkage members 30 on the same side can always be kept at an equal spacing distance, so that a parallelogram structure is formed between the two linkage members 30, the driving wheel 22, the driven wheel 23 and the connecting member 41, so that the two linkage members 30 always remain parallel to each other during the rotation process, and then the connecting member 41 always remains in a vertical state, avoiding the direction posture of the connecting member 41 from shifting and causing the workpiece adsorbed by the suction member 42 to shift accordingly, so that the connecting member 41 drives the workpiece adsorbed on the suction member 42 to maintain the preset direction posture when it moves to the preset position, thereby improving the material transfer stability.

[0059] The connecting member 41 includes a connecting portion 411 rotatably connected to the linkage member 30, two first rotating shafts 412 passing through the connecting portion 411, and two first bearings 413 sleeved on the corresponding first rotating shafts 412. The connecting portion 411 is generally in the shape of a long strip, and is disposed at one end of the linkage member 30 away from the driving member 21 and connected to the suction member 42. The two first rotating shafts 412 are both generally in the shape of a rod, and are arranged parallel to and vertically spaced from the connecting portion 411. The two first rotating shafts 412 are respectively passed through the connecting portion 411 and the corresponding linkage member 30, so that the two linkage members 30 are both rotatably connected to the connecting portion 411. The two first bearings 413 are respectively sleeved on the corresponding first rotating shafts 412 and are both embedded in the connecting portion 411. Exemplarily, the first bearings 413 are rolling bearings.

[0060] In this way, by setting two first rotating shafts 412 respectively passing through the connection part 411 and the corresponding linkage member 30, the two ends of each linkage member 30 can be respectively connected to the connection part 411 and the corresponding rotating part 221 for rotation, so that the two linkage members 30 can synchronously drive the connection part 411 to rotate under the drive of the driving wheel 22 and the driven wheel 23, so as to realize the rapid movement of the workpiece adsorbed by the material suction member 42 to the preset position, without manual operation for material transfer, and improve the material transfer efficiency. In addition, by setting two first bearings 413 on the corresponding first rotating shafts 412, direct contact between the first rotating shafts 412 and the connection part 411 can be avoided, and the force applied to the connection part 411 by the linkage member 30 through the first rotating shaft 412 can be reduced, so that the two linkage members 30 can stably drive the connection part 411 to rotate.

[0061] It can be understood that the connecting portion 411 is provided with a hollow groove 4111, and the hollow groove 4111 runs through two opposite sides of the connecting portion 411, and the hollow groove 4111 is used to reduce the weight of the connecting portion 411, so that the connecting portion 411 can stably drive the suction member 42 to rotate.

[0062] The suction member 42 includes a support portion 421 connected to the connecting member 41 and a suction portion 422 connected to the support portion 421. The support portion 421 is generally in the shape of a long strip, and the support portion 421 is arranged on the connecting member 41 in a direction perpendicular to the extending direction of the connecting member 41 and is connected to the connecting member 41. The suction portion 422 is detachably connected to the support portion 421 and is used to absorb the workpiece.

[0063] In this way, by providing the above-mentioned support part 421, the support part 421 can support the workpiece adsorbed on the suction part 422, and at the same time keep the support part 421 and the connecting member 41 perpendicular to each other, so that the support part 421 and the suction part 422 connected thereto can always remain stable in the horizontal direction, thereby making the workpiece adsorbed on the suction part 422 maintain a preset orientation and posture, so that the suction part 422 can place the workpiece at a preset position according to the preset orientation and posture. In addition, by providing a detachable connection between the suction part 422 and the support part 421, it is convenient to replace different types of suction parts 422 according to different material transfer requirements, so as to improve the application range of the material transfer device 100.

[0064] It can be understood that there are multiple suction parts 422, and multiple suction parts 422 are arranged on the support part 421 at intervals along the extension direction of the support part 421 and are all detachably connected to the support part 421. In this way, by providing multiple suction parts 422, the suction member 42 can absorb multiple workpieces at the same time, and drive the multiple workpieces absorbed on the suction parts 422 to move synchronously, thereby improving the material transfer efficiency of the material transfer device 100.

[0065] The suction part 422 includes a fixed body 4221 connected to the support part 421, a suction body 4222 connected to the fixed body 4221, and a locking body 4223 penetrating the fixed body 4221. The fixed body 4221 is roughly block-shaped, and the fixed body 4221 is arranged on the side of the support part 421 away from the connecting member 41. The suction body 4222 is roughly cylindrical, and the suction body 4222 is arranged at one end of the fixed body 4221 away from the connecting member 41 and is detachably connected to the fixed body 4221. The locking body 4223 is roughly rod-shaped, and the locking body 4223 passes through the fixed body 4221 and is threadedly connected to the support part 421, so that the fixed body 4221 is detachably connected to the support part 421. Exemplarily, the suction body 4222 is any adsorption block, adsorption rod or similar adsorption member that is connected to an external air source and can adsorb workpieces, and the locking body 4223 is a screw.

[0066] In this way, by setting the locking body 4223 to pass through the fixed body 4221 and be threadedly connected to the support part 421, a detachable connection structure can be formed between the fixed body 4221 and the support part 421, which is convenient for the operator to quickly replace the suction part 422 that meets the material transfer requirements.

[0067] The fixed body 4221 is threadedly connected to the material suction body 4222. Since the height difference between the material suction body 4222 and the workpiece is inconsistent when the material transfer device 100 transfers different types of workpieces, by setting a threaded connection between the fixed body 4221 and the material suction body 4222, it is convenient for the operator to adjust the height of the material suction body 4222 to a preset height according to different workpieces, so that the preset height difference is maintained between the material suction body 4222 and the workpiece to be transferred, avoiding collision between the material suction body 4222 and the workpiece, which is conducive to ensuring that the material suction body 4222 transfers the workpiece stably.

[0068] The working process of the above-mentioned material moving device 100 is roughly as follows:

[0069] First, the suction member 42 absorbs the workpiece, which can avoid manual operation from frequently contacting the workpiece and damaging the workpiece, thereby improving the quality of the workpiece. Then, the driving member 21 drives the driving wheel 22 to rotate in a preset direction, so that the driving wheel 22 drives the driven wheel 23 to rotate synchronously through the belt 24.

[0070] Then, since the two linkage members 30 are of equal length and arranged in parallel, and the opposite ends of the two linkage members 30 are rotatably connected to the corresponding rotating parts 221 and the connecting member 41 respectively, the spacing between the ends of the two linkage members 30 on the same side can always maintain a relative spacing distance, so that the driving wheel 22, the driven wheel 23, the two linkage members 30 and the connecting member 41 form a parallelogram structure, and the two linkage members 30 use the parallelogram structure to rotate synchronously and always maintain a state of being parallel to each other under the drive of the driving wheel 22 and the driven wheel 23, thereby driving the connecting member 41 and the workpiece adsorbed by the suction member 42 to rotate to a preset position, and at the same time, the workpiece adsorbed on the suction member 42 always maintains a preset posture and orientation during the material transfer process, and the workpiece is placed in the preset position according to the preset posture and orientation, thereby realizing a mechanized transfer of the workpiece to the preset position, without the need for manual material transfer, thereby improving the material transfer efficiency;

[0071] Finally, the driving member 21 drives the active wheel 22 to rotate in a direction opposite to the preset direction, and the active wheel 22 drives the driven wheel 23 to rotate synchronously in the opposite direction through the belt 24, so that the active wheel 22 and the driven wheel 23 drive the two linkage members 30 to drive the connecting member 41 and the suction member 42 to rotate to the initial position, which facilitates the material moving device 100 to repeat the material moving operation and further improves the material moving efficiency.

[0072] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present application and are not intended to limit it. Although the present application has been described in detail with reference to the preferred embodiments, a person of ordinary skill in the art should understand that the technical solution of the present application may be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the present application.
