Description

Technical Field

[0001] The present application relates to the field of automated transmission, and in particular to a synchronous belt conveying device for improving conveying accuracy. Background Art

[0002] In the field of automated transportation, when transporting spherical or cylindrical workpieces, it is found that since the workpieces are prone to rolling, especially for some workpieces with features on the side, the workpieces need to be positioned before transportation and the position of the workpieces needs to be adjusted using an adjustment mechanism to ensure that the positions of the features on the workpieces are consistent. At the same time, it is also necessary to ensure that the position of the workpiece remains unchanged during the transportation process, so as to ensure the transportation accuracy of the workpiece.

[0003] However, the above approach requires additional adjustment equipment at the upstream end of the transfer device, increasing the complexity of the structure and the risk of interference. Furthermore, the need to adjust the position of the workpiece before transfer increases the time between transfers, resulting in low transfer efficiency. Summary of the Invention

[0004] Based on this, it is necessary to ensure both the conveying accuracy and the transmission efficiency of the synchronous belt conveyor equipment.

[0005] The present application provides a synchronous belt conveying device with improved conveying accuracy, comprising: A conveyor belt, comprising a belt and a plurality of brackets, the plurality of brackets being arranged on the belt, the brackets being used to carry workpieces, and driven by the belt, the workpieces being conveyed from bottom to top along a first straight line direction, the brackets having a V-shaped bearing surface and a first elastic limit block provided on the bearing surface; The transfer plate extends along the first straight line direction, and the transfer plate contacts the workpiece loaded on the bracket. The bracket moves with the belt, and the workpiece loaded on the bracket rubs the transfer plate, causing the workpiece to rotate, and finally the workpiece cooperates with the first limit block to limit the rotation of the workpiece.

[0006] In one embodiment, the first straight line direction is inclined relative to a horizontal plane.

[0007] In one embodiment, a top plate is further included, and the top plate is arranged parallel to the transfer plate, and the workpiece loaded on the bracket is located between the top plate and the transfer plate.

[0008] In one embodiment, the workpiece includes a tube portion and a groove provided on the tube portion; When the pipe portion is pressed against the first limit block, the first limit block is deformed; When the groove is set corresponding to the first limiting block, the deformed first limiting block is restored and the first limiting block extends into the groove.

[0009] In one embodiment, the contact surface between the transfer plate and the workpiece is a friction surface, and the contact surface between the top plate and the workpiece is a smooth surface.

[0010] In one embodiment, the synchronous transmission belt further comprises a drive, which drives the belt to move.

[0011] In one embodiment, the driver is a stepper motor.

[0012] In one embodiment, when the workpiece is transferred to the top end of the belt along with the support, the first limiting block extends into the groove.

[0013] In one embodiment, it further includes: Hopper: The hopper is located at the bottom of the belt; The transfer part corresponds to the bracket setting at the top end of the belt; The pusher part is used to transfer the workpiece on the top of the belt to the transfer part.

[0014] In one embodiment, the transfer portion includes a receiving groove and a second limiting block, and the second limiting block is flush with the first limiting block of the top upper bracket.

[0015] In the above-mentioned synchronous belt conveying equipment, during the process of transferring the workpiece, the transfer plate and the workpiece on the bracket move relative to each other due to friction, and the workpiece rotates with the transfer plate to automatically adjust the position of the workpiece during the transfer process. As the workpiece rotates, the characteristic position on the side of the workpiece rotates to cooperate with the first limit block, so that the workpiece and the first limit block form a limit structure to achieve workpiece positioning, that is, the friction between the transfer plate and the workpiece makes it difficult to drive the workpiece to rotate. The workpiece is positioned during the transmission process through the transfer plate and the first limit block in the synchronous belt conveying equipment, which not only ensures the accuracy of the workpiece transmission, but also ensures the efficiency of the workpiece transmission.

[0033] See Figure 1 、 2 As shown, an embodiment of the present application provides a synchronous belt conveyor device for improving conveying accuracy, comprising: a synchronous transmission belt 11, a hopper 12, a transfer unit 13, and a pusher unit 14. The hopper 12 is located at the upstream end of the synchronous transmission belt 11, and the transfer unit 13 and the pusher unit 14 are located at the downstream end of the synchronous transmission belt 11. The hopper 12 is used to store multiple workpieces 2. The workpieces 2 in the hopper 12 are fed one by one onto the synchronous transmission belt 11, and the workpieces 2 are ultimately fed to the transfer unit 13 along the synchronous transmission belt 11. The synchronous transmission belt 11 includes a belt 111, a drive 112, and a plurality of brackets 113. The brackets 113 are arranged on the belt 111. The brackets 113 are used to carry the workpieces 2. Driven by the belts 111, the workpieces 2 are conveyed from bottom to top along a first straight line. The synchronous transmission belt 11 has two belts 111, and the brackets 113 on the two belts 111 are correspondingly arranged so that the same workpiece 2 is carried on the brackets 113 on the two belts 111. In this embodiment, the belt 111 can be understood as comprising a transmission belt and a pulley connected to the transmission belt. The pulleys within the two belts 111 are connected via a synchronous shaft, so that the driver 112 drives one of the belts 111, which in turn drives the other belt 111 in synchronous motion via the synchronous shaft. The aforementioned first linear direction specifically refers to a first linear direction inclined relative to the horizontal plane. The workpiece 2 is pressed against the bracket 113 by its own weight. Exemplarily, the driver 112 is a stepper motor.

[0034] It can be understood that the hopper 12 is provided at the upstream end of the synchronous conveyor 11, that is, the hopper 12 is installed at the bottom end of the synchronous conveyor 11. After the workpiece 2 is transferred to the hopper 12, the workpiece 2 rolls onto the bracket 113 located at the bottom end of the synchronous conveyor 11, and then the workpiece 2 moves along the first straight line direction with the bracket 113. The transfer portion 13 and the pusher portion 14 are provided at the downstream end of the synchronous conveyor 11, that is, the transfer portion 13 and the pusher portion 14 are located at the top end of the synchronous conveyor 11. The pusher portion 14 pushes the workpiece 2 on the bracket 113 located at the top end of the synchronous conveyor 11 into the transfer portion 13.

[0035] Specifically, the bracket 113 has a V-shaped bearing surface 1131 and a first elastic stopper 1132 disposed on the bearing surface 1131. The bearing surface 1131 has two surfaces tangential to the workpiece 2, allowing a circular workpiece 2 to be stably supported on the bracket 113. The first stopper 1132 is located at the corner of the bearing surface 1131. The elastic first stopper 1132 can elastically deform or recover in one direction.

[0036] Combine Figure 3-6 As shown, the synchronous belt conveying equipment also includes a transfer plate 16, which extends along the first straight line direction, and the transfer plate 16 contacts the workpiece 2 loaded on the bracket 113. For example, the transfer plate 16 is located below the workpiece 2, and the workpiece 2 is pressed against the transfer plate 16 by its own gravity to increase friction. The bracket 113 moves with the belt 111, so that the workpiece 2 loaded on the bracket 113 slides relative to the transfer plate 16, and the workpiece 2 rubs against the transfer plate 16, causing the workpiece 2 to rotate in one direction. The position of the workpiece 2 itself is adjusted by the unidirectional rotation of the workpiece 2, and finally the workpiece 2 cooperates with the first limit block 1132 to limit the rotation of the workpiece 2, thereby achieving the positioning of the workpiece 2. It can be understood that when the workpiece 2 moves to the downstream end of the synchronous transmission belt 11, the position of the workpiece 2 is consistent.

[0037] In this embodiment, the workpiece 2 includes a tube portion 21 and a groove 22 provided on the side of the tube portion 21. For example, the groove 22 extends along the axial direction of the tube portion 21. Figure 6 , and refer to Figure 7 As shown, the side surface of the tube portion 21 is pressed onto the first limit block 1132, causing the first limit block 1132 to elastically deform and be compressed to a length of L1. Figure 8 As shown, after the workpiece 2 rotates, it rotates relative to the first stopper 1132, causing the groove 22 to correspond to the first stopper 1132. Specifically, the first stopper 1132 is positioned toward the groove 22, and the first stopper 1132 resumes its extension into the groove 22. At this point, the first stopper 113 returns to its length L2, where L2 > L1. The first stopper 113, with a length of L2, can extend into the groove 22, limiting the rotation of the workpiece 2 and thereby achieving positioning of the workpiece 2. When the workpiece 2 moves to the downstream end of the synchronous conveyor 11, the grooves 22 of the workpiece 2 are all facing downward, ensuring high positioning accuracy for the workpiece 2. In this solution, the elastic deformation direction of the first limit block 1132 is the length direction of the first limit block 113. It can be understood that the length direction of the first limit block 113 is parallel or approximately parallel to the gravity direction G of the workpiece 2, so that most or all of the gravity of the workpiece 2 is pressed on the first limit block 113, causing the first limit block 113 to deform.

[0038] Because the workpiece 2 rolls from the hopper 12 to the support 113, its position on the support 113 is uncertain (specifically, the position of the groove 22 is difficult to determine). To ensure the accurate position of the workpiece 2 during discharge (specifically, the position of the groove 22 is fixed), the transfer plate 16 and the workpiece 2 on the support 113 undergo frictional relative motion, causing the workpiece 2 to rotate, thereby automatically adjusting its position during transfer. As the workpiece 2 rotates, the feature on its side (i.e., the groove 22) rotates to mate with the first stopper 1132, forming a retaining structure between the workpiece 2 and the first stopper 1132 and securing the workpiece 2. Subsequently, friction between the transfer plate 16 and the workpiece 2 makes it difficult to rotate the workpiece. When the workpiece 2 is transferred to the downstream end of the synchronous conveyor 11, the workpiece 2 and the support 113 remain stationary. The transfer plate 16 and the first stopper 1132 ensure the accurate and efficient transfer of the workpiece 2.

[0039] Furthermore, the synchronous belt conveyor apparatus includes a top plate 15, which is arranged parallel to a transfer plate 16. The workpiece 2 loaded on the bracket 113 is positioned between the top plate 15 and the transfer plate 16. During the conveyance process, the workpiece 2 is arranged tangentially to the top plate 15 and the transfer plate 16. The top plate 15 and the transfer plate 16 restrict the floating of the workpiece 2, ensuring stable contact between the workpiece 2 and the transfer plate 16 when the workpiece 2 is transferred between the top plate 15 and the transfer plate 16, thereby improving the rotation efficiency of the workpiece 2.

[0040] Specifically, the contact surface between the transfer plate 16 and the workpiece 2 is a friction surface, and the friction force of the transfer plate 16 on the workpiece 2 is large. The contact surface between the top plate 15 and the workpiece 2 is a smooth surface, and the friction force of the top plate 15 on the workpiece 2 is small. Since the workpiece 2 only has friction on one side, the workpiece 2 rotates in one direction.

[0041] Furthermore, refer to Figure 9 As shown, the transfer portion 13 includes a receiving groove 131 and a second stopper 132. The second stopper 132 is flush with the first stopper 1132 of the top bracket 113. The transfer portion 13 is located on the side of the bracket 113 at the top of the synchronous transmission belt 11, so that the second stopper 132 is aligned with the first stopper 1132 of the top bracket 113. The workpiece 2 is pushed from the bracket 113 to the transfer portion 13, and the groove 22 is smoothly transferred from the first stopper 1132 to the second stopper 132. Exemplarily, the receiving groove 131 is a U-shaped groove, and the second stopper 132 is provided on the bottom surface of the receiving groove 131. The workpiece 2 can be accommodated in the receiving groove 131.

[0042] In this embodiment, the pusher 14 includes a cylinder 141 and a push block 142. The push block 142 is mounted on the power output end of the cylinder 141. The push block 142 contacts the side of the workpiece 2, pushing the workpiece 2 into the receiving groove 131 from one side. Specifically, the push block 142 contacts the side surfaces of the tube 21 and the groove 22, and the push block 142 passes through the axis of the workpiece 2.

[0043] In some embodiments of the present application, Figure 2 、 4 , and combined with Figure 10 As shown, the hopper 12 includes a base plate 121 and guide side plates 122. The guide side plates 122 include a first guide plate 1221 and a second guide plate 1222. There are two guide side plates 122, which are located on either side of the workpiece 2 on the bracket 113 and are symmetrically arranged. The first guide plate 1221 is combined with the second guide plate 1222, and the second guide plate 1222 is connected to the base plate 121. The two second guide plates 1222 are closed inward, that is, the distance between the two second guide plates 1222 gradually decreases. The two first guide plates 1221 are arranged in parallel, and the distance between the two first guide plates 1221 is the length of the workpiece 2. The guide side plates 122 guide the workpiece 2 along the first straight line relative to the bracket 113.

[0044] In this solution, the top plate 15 , the transfer plate 16 and the two guide side plates 122 are used to limit the position of the workpiece 2 in four directions during the transmission process, so that the workpiece 2 can only be transmitted along the first straight line direction.

[0045] Furthermore, the bottom plate 121 is provided with a first avoidance opening 1211 and a second avoidance opening 1212 extending therethrough. There are two first avoidance openings 1211, and the first avoidance opening 1211 is used to allow the bracket 113 to pass through. The second avoidance opening 1212 is located between the two first avoidance openings 1211 and is used to connect to the transfer plate 16. By increasing the length of the transfer plate 16, the angle through which the workpiece 2 can be rotated is increased to accommodate a wider variety of workpieces 2. The synchronous conveyor 111 is a circulating conveyor. After the bracket 113 on the conveyor 11 moves from bottom to top, it will be transferred to the bottom end of the conveyor 11 again after a cycle. In order to facilitate the bracket 113 to pass through the hopper 12, the first avoidance opening 1211 is provided on the bottom plate 121. At the same time, the bracket 113 passes through the first avoidance opening 1211, and the workpiece 2 in the hopper 12 can be located on the moving path of the bracket 113, so that the bracket 113 can load the workpiece 2.

[0046] In some embodiments of the present application, Figure 2 、 36, the bracket 113 is an annular structure to improve the structural stability of the bracket 113. Exemplarily, the bracket 113 has an L-shaped profile, the short side of the bracket 113 is mounted on the belt 111, and the V-shaped bearing surface 1131 serves as the inner profile of the bracket 113.

[0047] Specifically, the angle formed by the bearing surface 1131 is an obtuse angle, so that a larger projection area of ​​the workpiece 2 along its gravity direction G is located on the bearing surface 1131, thereby improving the loading stability of the workpiece 2. At the same time, the obtuse angle formed by the bearing surface 1131 can make the contour surface of the workpiece 2 closer to the angle position of the bearing surface 1131, thereby reducing the length of the first limit block 1132. After the workpiece 2 is matched with the first limit block 1132, the transfer plate 16 may continue to rub against the workpiece 2. At this time, stress is generated on the first limit block 1132. The surface area of ​​the groove 22 in the workpiece 2 is much smaller than the surface area of ​​the tube 21, resulting in the volume of the first limit block 1132 being too small compared to the volume of the workpiece 2. The strength of the first limit block 1132 is difficult to guarantee, and when the workpiece 2 generates stress on the first limit block 1132, the first limit block 1132 is more likely to break due to the stress. In this solution, since the bearing surface 1131 is designed to shorten the length of the first limiting block 1132 , the stress on the first limiting block 1132 can be effectively reduced, thereby increasing the service life of the first limiting block 1132 .

[0048] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0049] The above embodiments merely illustrate several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, all of which fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
