Description

Technical Field

[0001] The present application relates to the technical field of processing equipment, and in particular to a rotary positioning device. Background Art

[0002] During the assembly process of electronic equipment, it is necessary to transfer the incoming materials to the processing area. However, some feeding devices cannot distinguish the positive and negative directions of the incoming materials when providing materials, resulting in the reverse placement of the materials supplied to the rear end. In order to solve this problem, the existing positioning and rotating positioning device includes a pushing assembly composed of a cylinder and a clamping block. After the pushing assembly clamps the material, the material is rotated to correct the direction of the material, and then the pushing assembly releases the material.

[0003] However, the above method has the following problems: the pushing component is large in size, resulting in a large rotation radius; the pushing component requires wiring, such as connecting wires, air pipes or signal lines, which limits the rotation angle and makes it difficult to achieve a rotation angle of more than 360°; after multiple rotations, the wires, air pipes or signal lines connected to the pushing component will be damaged, increasing the equipment failure rate and reducing the equipment stability. Utility Model Content

[0004] In view of the above, it is necessary to propose a rotation positioning device that can rotate and adjust the direction of the workpiece, reduce the rotation radius, reduce the influence of wiring on the rotation, and increase the degree of freedom of rotation.

[0005] The cam is connected to the support member so as to enable the movable member to move relative to the support member, so that the movable member can move relative to the support member, thereby enabling the movable member to move relative to the support member, thereby preventing the movable member from moving relative to the support member, thereby preventing the movable member from moving relative to the support member, thereby preventing the movable member from moving relative to the support member, thereby preventing the movable member from moving relative to the support member, thereby preventing the movable member from moving relative to the support member,

[0006] The above-mentioned rotary positioning device can carry workpieces through the loading trough of the material carrier. When placing the workpiece, the clamping assembly pushes the sliding member of the pushing assembly toward the connecting member, and the sliding member drives the push rod to move toward the connecting member, so as to facilitate the placement of the workpiece in the loading trough. After the workpiece is placed in the loading trough, the clamping assembly releases the sliding member, the elastic member pushes the sliding member away from the connecting member, the sliding member drives the push rod to move, and the push rod pushes the workpiece to the trough wall of the loading trough to fix the workpiece. The material carrier and the pushing assembly can be driven to rotate in the horizontal plane by the rotating assembly, thereby realizing the rotation of the workpiece to adjust the direction of the workpiece. After the rotation of the workpiece is completed, the workpiece can be taken out of the loading trough. Since the elastic force provided by the elastic member drives the push rod to push the workpiece, the workpiece can be directly taken out of the loading trough without pushing the sliding member to drive the push rod to release the workpiece in advance, thereby reducing the working steps and effectively improving the working efficiency. The above-mentioned rotation positioning device, in which the clamping assembly and the tightening assembly are separately arranged, can effectively reduce the rotation radius. The tightening assembly provides power through its own elastic parts and does not need to be connected to additional structures such as power cords or air pipes. This can avoid the influence of power cords or air pipes on the rotation angle during rotation, and the degree of rotation freedom is high.

[0007] In some embodiments, the rotating assembly includes a rotating drive member and two support arms, the two support arms are connected to the rotating drive member and are spaced apart, one end of the two support arms away from the rotating drive member is connected to the carrier, the sliding member is arranged between the two support arms, and the rotating drive member drives the carrier and the pushing assembly to rotate around the center of the carrier through the support arms.

[0008] In some embodiments, the clamping assembly includes an clamping drive and a pushing member, the clamping drive is spaced apart from the rotating assembly, the pushing member is connected to the output end of the clamping drive and is arranged opposite to the sliding member, and the clamping drive is used to drive the pushing member to push the sliding member toward the connecting member to allow the workpiece to be placed.

[0009] In some embodiments, the rotational positioning device also includes a detection component, which includes a support frame, a support plate and a plurality of detectors, the rotation component and the clamping component are both fixedly connected to the support frame, the support plate is connected to the support frame and is arranged adjacent to the carrier, the plurality of detectors are all connected to the side of the support plate away from the support frame and are arranged at intervals, and the plurality of detectors are all used to detect the position of the workpiece in the loading trough.

[0010] In some embodiments, the support plate is an annular structure, the carrier is arranged on the inner side of the support plate, a plurality of detectors are connected to the support plate and arranged around the carrier, and the two sides of the carrier adjacent to the support plate are arranged in an arc shape.

[0011] In some embodiments, blocks are provided at both ends of the loading trough, each of the blocks is detachably connected to the loading member, and the connection position between the block and the loading member is adjustable, and the block is used to clamp the workpiece in the loading trough.

[0012] In some embodiments, the pushing assembly further includes a slide rail, wherein the slide rail is disposed between the material carrier and the sliding member, the slide rail is fixedly connected to the material carrier, and the sliding member is slidably connected to the slide rail.

[0013] In some embodiments, the material carrier is further provided with a limiting hole passing through the material carrier, and the pushing assembly further comprises a limiting block, which is connected to the sliding member and movably inserted into the limiting hole, and the limiting block abuts against the hole wall of the limiting hole when moving with the sliding member to limit the moving distance of the sliding member.

Some embodiments of the present application will be described in detail below in conjunction with the accompanying drawings.

[0051] The embodiments of the present application are further described below in conjunction with the accompanying drawings.

[0052] See also Figure 1 An embodiment of the present application provides a rotation positioning device 100, which is used to rotate and position a workpiece 200. The workpiece 200 can be a strip-shaped, column-shaped, or other structure. The rotation positioning device 100 includes a carrier 10, a clamping assembly 20, a rotation assembly 30, and a clamping assembly 40.

[0053] Specifically, see Figures 1 to 3 , the material carrier 10 is provided with a material loading groove 11 for carrying the workpiece 200, and the material carrier 10 is also provided with an active hole 12 that penetrates the material carrier 10 and is connected to the material loading groove 11. The material carrier 10 can be a plate-like structure, and the structure of the material loading groove 11 is adapted to the structure of the workpiece 200, such as a long strip. It can be understood that the area of ​​the material loading groove 11 is larger than the area of ​​the workpiece 200, so as to facilitate the placement of the workpiece 200. The active hole 12 can be a square hole, a strip hole, etc., and the active hole 12 can be provided with one, two, three, etc., and each active hole 12 is connected to the bottom of the groove of the material loading groove 11. The material loading groove 11 on the material carrier 10 can be provided with one, two, three, etc., and the specific number of the material loading grooves 11 and the position of the material loading grooves 11 on the material carrier 10 can be set according to actual needs, and are not limited here. It can be understood that when a plurality of material loading grooves 11 are provided on the material carrier 10, the extension directions of the plurality of material loading grooves 11 are parallel to each other, and each material loading groove 11 is correspondingly connected with an active hole 12.

[0054] The pushing assembly 20 includes a sliding member 21, a connecting member 22, an elastic member 23 and a push rod 24. The sliding member 21 is slidably connected to the side of the carrier 10 away from the loading trough 11. The connecting member 22 is fixedly connected to the carrier 10 and is spaced apart from the sliding member 21. The two ends of the elastic member 23 are respectively abutted against the sliding member 21 and the connecting member 22. The elastic member 23 is used to elastically push the sliding member 21 away from the connecting member 22. The push rod 24 is connected to the sliding member 21 and is movably inserted in the movable hole 12. The push rod 24 is used to push the workpiece 200 to fix the workpiece 200.

[0055] The sliding member 21 may be a plate-like structure, which can provide a stable support for the push rod 24. The connecting member 22 may be a block-like structure. When the connecting member 22 is connected to the material carrier 10, it protrudes from the side of the material carrier 10 away from the material loading slot 11 and corresponds to the sliding member 21. The elastic member 23 may be a spring. In one embodiment, in order to improve the stability of the elastic member 23 pushing the sliding member 21, the pushing assembly 20 is provided with two elastic members 23, which are arranged side by side and are both connected to the sliding member 21 and the connecting member 22. The number and position of the push rod 24 may correspond to the number and position of the movable holes 12 in the same material loading slot 11. For example, the push rod 24 is provided with one, two, three, etc. When multiple push rods 24 are provided, the stability of the workpiece 200 when the push rod 24 is against the workpiece 200 can be improved. It can be understood that when there are multiple material loading slots 11, the number and position of the push rod 24 correspond to the movable holes 12 in each material loading slot 11.

[0056] The rotating assembly 30 is arranged at the lower side of the material carrier 10 and connected to the material carrier 10. The rotating assembly 30 is used to drive the material carrier 10 and the pushing assembly 20 to rotate around the center of the material carrier 10. It can be understood that when the rotating assembly 30 drives the material carrier 10 to rotate, the pushing assembly 20 moves synchronously with the material carrier 10. When it is necessary to reverse the positive and negative directions of the workpiece 200, the rotating assembly 30 drives the material carrier 10 and the pushing assembly 20 to rotate 180°, and the material carrier 10 and the pushing assembly 20 cooperate to drive the workpiece 200 to rotate 180° to complete the turning of the workpiece 200, and the workpiece 200 can be taken away at this time. It can be understood that if the workpiece 200 needs to be rotated to other angles, the rotating assembly 30 drives the material carrier 10 and the pushing assembly 20 to rotate the corresponding angle, and the angle at which the rotating assembly 30 drives the material carrier 10 to rotate can be any angle.

[0057] The clamping assembly 40 is spaced apart from the rotating assembly 30, and the clamping assembly 40 is used to push the sliding member 21 toward the connecting member 22, so that the push rod 24 moves toward the connecting member 22. When the workpiece 200 needs to be placed, the clamping assembly 40 pushes the sliding member 21 toward the connecting member 22, and the sliding member 21 drives the push rod 24 to move away from the loading slot 11, thereby facilitating the placement of the workpiece 200 in the loading slot 11. After the workpiece 200 is placed in the loading slot 11, the clamping assembly 40 releases the sliding member 21, and the sliding member 21 moves away from the connecting member 22 under the push of the elastic member 23, thereby driving the push rod 24 to hold the workpiece 200 against the slot wall of the loading slot 11 to position the workpiece 200. The rotating assembly 30 then drives the loading member 10 and the pushing assembly 20 to rotate, so that the workpiece 200 rotates 180°.

[0058] The rotary positioning device 100 provided in the embodiment of the present application can carry the workpiece 200 through the loading slot 11 of the material carrier 10. When placing the workpiece 200, the clamping assembly 40 pushes the sliding member 21 of the pushing assembly 20 to move toward the connecting member 22, and the sliding member 21 drives the push rod 24 to move toward the connecting member 22, so as to facilitate the placement of the workpiece 200 in the loading slot 11. After the workpiece 200 is placed in the loading slot 11, the clamping assembly 40 releases the sliding member 21, the elastic member 23 pushes the sliding member 21 away from the connecting member 22, and the sliding member 21 drives the push rod 24 to move, and the push rod 24 pushes the workpiece 200 to the slot wall of the loading slot 11 to fix the workpiece 200. The rotating assembly 30 can drive the material carrier 10 and the pushing assembly 20 to rotate in the horizontal plane, thereby realizing the rotation of the workpiece 200 to adjust the direction of the workpiece 200. After the workpiece 200 has completed its rotation, the workpiece 200 can be taken out from the loading trough 11. Since the elastic force provided by the elastic member 23 drives the push rod 24 to push the workpiece 200, the workpiece 200 can be directly taken out from the loading trough 11 without having to push the sliding member 21 in advance to drive the push rod 24 to release the workpiece 200, thereby reducing the working steps and effectively improving the working efficiency.

[0059] The rotation positioning device 100 provided in the embodiment of the present application has a clamping assembly 40 and a pushing assembly 20 that are separately arranged, which can effectively reduce the rotation radius. The pushing assembly 20 is powered by its own elastic member 23, and does not need to be connected to additional structures such as power cords or air pipes. This can avoid the influence of power cords or air pipes on the rotation angle during rotation, and has a high degree of rotation freedom.

[0060] In other embodiments, the rotary positioning device 100 provided in the present application can also be used for centrifugal operations, such as centrifugal separation of oil stains, water stains, debris, etc. on the surface of the workpiece 200. During the operation, the workpiece 200 is installed in the loading trough 11 and fixed by the pushing assembly 20, and then the rotating assembly 30 drives the loading part 10 and the workpiece 200 to rotate rapidly, so that the oil stains, water stains, debris, etc. on the surface of the workpiece 200 can be thrown out.

[0061] In some embodiments, see Figure 1 and Figure 2 The rotating assembly 30 includes a rotating driving member 31 and two supporting arms 32. The two supporting arms 32 are connected to the rotating driving member 31 and are arranged at intervals. One end of the two supporting arms 32 away from the rotating driving member 31 is connected to the material carrier 10. The sliding member 21 is arranged between the two supporting arms 32. The rotating driving member 31 drives the material carrier 10 and the pushing assembly 20 to rotate around the center of the material carrier 10 through the supporting arms 32. The rotating driving member 31 can be a rotating cylinder, a rotating motor, a stepping motor, etc. The supporting arms 32 can be a block structure. The rotating driving member 31 is connected to the material carrier 10 through the two supporting arms 32, and can drive the material carrier 10 to rotate through the supporting arms 32. At the same time, the two supporting arms 32 are arranged at intervals, which is convenient for avoiding the pushing assembly 20 and does not affect the operation of the pushing assembly 20.

[0062] In some embodiments, see Figure 1 The clamping assembly 40 includes a clamping drive member 41 and a push member 42. The clamping drive member 41 is spaced apart from the rotating assembly 30. The push member 42 is connected to the output end of the clamping drive member 41 and is arranged opposite to the sliding member 21. The clamping drive member 41 is used to drive the push member 42 to push the sliding member 21 to move toward the connecting member 22 to allow the workpiece 200 to be placed. The clamping drive member 41 can be a cylinder, etc., and the push member 42 can be a plate-shaped or block-shaped structure. It can be understood that the height of the push member 42 is the same as that of the sliding member 21. When the sliding member 21 is opposite to the push member 42, the clamping drive member 41 drives the push member 42 to move, so that the push member 42 pushes the sliding member 21 to move toward the connecting member 22, thereby putting the push rod 24 in an open state.

[0063] In some embodiments, see Figure 1The rotary positioning device 100 further includes a detection assembly 50, which includes a support frame 51, a support plate 52 and a plurality of detectors 53. The rotating assembly 30 and the clamping assembly 40 are both fixedly connected to the support frame 51. The support plate 52 is connected to the support frame 51 and is disposed adjacent to the material carrier 10. The plurality of detectors 53 are all connected to the side of the support plate 52 away from the support frame 51 and are disposed at intervals. The plurality of detectors 53 are all used to detect the position of the workpiece 200 in the material carrier 11. The support frame 51 may be a combination structure of a bottom plate 511 and a plurality of support columns 512. The support plate 52 is connected to the plurality of support columns 512. The rotating assembly 30 and the clamping assembly 40 are both connected to the bottom plate 511. It can be understood that the height of the support plate 52 is consistent with the height of the material carrier 10. When the plurality of detectors 53 are connected to the support plate 52, the position of the workpiece 200 in the material carrier 11 can be detected. The detector 53 may be an infrared detector 53, a beam detector 53, etc. The detector 53 may be used to detect the structure of the workpiece 200 protruding from the carrier 10. At this time, after the workpiece 200 is placed in the loading slot 11, the detector 53 detects the workpiece 200, indicating that the workpiece 200 is placed in the correct position. If the workpiece 200 is not detected, it means that the workpiece 200 is placed in the wrong position and needs to be adjusted. Alternatively, the detector 53 is used to detect the position of the workpiece 200 after it is placed in the loading slot 11 and is accommodated in the loading slot 11. At this time, after the workpiece 200 is placed in the loading slot 11, the detector 53 does not detect the workpiece 200, indicating that the workpiece 200 is placed in the correct position. If the workpiece 200 is detected, it means that the workpiece 200 is misplaced and needs to be adjusted. The number and position of the detector 53 can be set according to actual needs, such as four, six, eight, etc., which are not limited here.

[0064] In some embodiments, see Figure 1 and Figure 3 , the support plate 52 is an annular structure, the carrier 10 is arranged on the inner side of the support plate 52, a plurality of detectors 53 are connected to the support plate 52 and arranged around the carrier 10, and the two sides adjacent to the carrier 10 and the support plate 52 are arranged in an arc shape. The support plate 52 is arranged in an annular shape, so that the support plate 52 can be arranged around the carrier 10, which is convenient for the multiple detectors 53 on the support plate 52 to be arranged around the carrier 10, so that the multiple detectors 53 can detect the position of the workpiece 200 from multiple angles, thereby improving the detection accuracy. At the same time, the annular support plate 52 will not affect the rotational movement of the carrier 10, and can protect the carrier 10 to prevent other objects from colliding with the carrier 10. The two sides adjacent to the carrier 10 and the support plate 52 are arranged in an arc shape, which can increase the use area of ​​the carrier 10 and will not affect the rotation of the carrier 10 in the support plate 52.

[0065] In some embodiments, see Figure 1 and Figure 2 , both ends of the loading trough 11 are provided with stoppers 13, each stopper 13 is detachably connected to the loading member 10, and the connection position between the stopper 13 and the loading member 10 is adjustable, and the stopper 13 is used to clamp the workpiece 200 in the loading trough 11. The stopper 13 can be movably connected to the loading member 10 by bolts, etc. It can be understood that different workpieces 200 may have different lengths. By providing the stopper 13, the position of the stopper 13 in the loading trough 11 can be adjusted when rotating workpieces 200 of different lengths, so that the two stoppers 13 cooperate to position the two ends of the workpiece 200.

[0066] In some embodiments, see Figure 1 and Figure 2 The pushing assembly 20 further includes a slide rail 25, which is disposed between the material carrier 10 and the sliding member 21. The slide rail 25 is fixedly connected to the material carrier 10, and the sliding member 21 is slidably connected to the slide rail 25. It can be understood that the extension direction of the slide rail 25 is consistent with the direction in which the sliding member 21 moves toward the connecting member 22. By providing the slide rail 25, the stability of the sliding member 21 when sliding relative to the material carrier 10 can be improved. The number of the slide rails 25 can be multiple, such as two or three, and the extension directions of the multiple slide rails 25 are parallel to each other. The provision of multiple slide rails 25 can further improve the stability of the sliding member 21 when it moves.

[0067] In some embodiments, see Figure 1 and Figure 2 The material carrier 10 is also provided with a limiting hole 14 that penetrates the material carrier 10, and the pushing assembly 20 also includes a limiting block 26, which is connected to the sliding member 21 and movably inserted in the limiting hole 14. The limiting block 26 abuts against the hole wall of the limiting hole 14 when moving with the sliding member 21 to limit the moving distance of the sliding member 21. The limiting hole 14 can be a square hole, a bar hole, etc., and the limiting block 26 can be a block, a column, etc. When the clamping assembly 40 pushes the sliding member 21 to move close to the connecting member 22, the limiting block 26 can abut against the hole wall of the limiting hole 14 close to the connecting member 22, thereby limiting the sliding member 21 from continuing to move toward the connecting member 22. When the elastic member 23 pushes the sliding member 21 to move away from the connecting member 22, the limiting block 26 can abut against the hole wall of the limiting hole 14 away from the connecting member 22, thereby limiting the sliding member 21 from continuing to move away from the connecting member 22, so that the moving distance of the sliding member 21 can be limited.

[0068] In some embodiments, see Figure 1 and Figure 2, the carrier 10 is provided with an adjusting member 15, which is connected to the side of the carrier 10 away from the connecting member 22 and extends into the limiting hole 14, and the adjusting member 15 is movably connected with the carrier 10 along the moving direction of the sliding member 21, and the adjusting member 15 is used to stop the limiting block 26 to adjust the moving distance of the limiting block 26 in the limiting hole 14. The adjusting member 15 can be a bolt, etc., and the adjusting member 15 and the carrier 10 can be connected in a threaded connection. It can be understood that the adjusting member 15 extends into the limiting hole 14, and when the elastic member 23 pushes the sliding member 21 to move away from the connecting member 22, the limiting block 26 can abut the adjusting member 15, thereby limiting the sliding member 21 from continuing to move away from the connecting member 22. Therefore, by adjusting the length of the adjusting member 15 extending into the limiting hole 14 , the moving distance of the limiting block 26 in the limiting hole 14 can be adjusted, thereby adjusting the distance of the sliding member 21 away from the connecting member 22 , thereby controlling the force with which the push rod 24 clamps the workpiece 200 .

[0069] In some embodiments, see Figure 1 , Figure 2 and Figure 3 The pushing assembly 20 further includes a stopper 27, which is adjustably connected to the connecting member 22 and arranged opposite to the sliding member 21, and is used to stop the sliding member 21 from moving toward the connecting member 22. The stopper 27 may be a bolt, etc., and the stopper 27 and the connecting member 22 may be connected by a threaded connection. It can be understood that when the clamping assembly 40 pushes the sliding member 21 to move toward the connecting member 22, the stopper 27 abuts against the sliding member 21 to stop the sliding member 21 from continuing to move toward the connecting member 22. By adjusting the length of the stopper 27 extending out of the connecting member 22, the distance that the sliding member 21 moves toward the connecting member 22 can be adjusted.

[0070] The working process of the rotation positioning device 100 provided in the embodiment of the present application is roughly as follows:

[0071] First, the rotating driving member 31 drives the carrier 10 and the pushing assembly 20 to rotate through the support arm 32, so that the sliding member 21 corresponds to the clamping assembly 40, and the clamping driving member 41 drives the pushing member 42 to move toward the sliding member 21, and the pushing member 42 pushes the sliding member 21 to move toward the connecting member 22, and the sliding member 21 drives the push rod 24 to move toward the connecting member 22, so that the push rod 24 is in an open state, and then the workpiece 200 can be placed in the loading trough 11.

[0072] After the workpiece 200 is placed, the detector 53 detects the position of the workpiece 200. After the workpiece 200 is placed in the correct position, the clamping drive member 41 drives the pushing member 42 to move away from the sliding member 21, and the elastic member 23 pushes the sliding member 21 to move away from the connecting member 22. The sliding member 21 drives the push rod 24 to move toward the workpiece 200 until the sliding member 21 abuts against the workpiece 200 to cooperate with the groove wall of the loading groove 11 to clamp the workpiece 200. At this time, the limit block 26 abuts against the adjusting member 15, and the installation of the workpiece 200 is completed.

[0073] Then the rotating driving member 31 drives the carrier 10 and the pushing assembly 20 to rotate again through the support arm 32. After the carrier 10 is rotated 180°, the workpiece 200 is reversed. At this time, an external device (not shown) such as a robot can directly take the workpiece 200 out of the carrier slot 11.

[0074] When the next workpiece 200 is reversed, the rotary driving member 31 rotates the material carrier 10 and the pushing assembly 20 again, so that the pushing assembly 20 corresponds to the clamping assembly 40, and then the above steps are repeated.
