[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0021] Refer to Figures 1 to 4, A bearing transfer device on a caster production line, including a workbench 1, several feeding tracks 2 arranged on the workbench 1, and a first feeding trough 21 inclined on the feeding track 2 and used for conveying bearings. The end of the first feeding trough 21 is connected to a second feeding trough 22 extending to the right. Below the second feeding trough 22, there is a first moving mechanism 3 that can move the bearings entering the second feeding trough 22 from the left side to the right side. The height of the side wall of the second feeding trough 22 is lower than that of the side wall of the first feeding trough 21. On the workbench 1 and on the right side of the feeding track 2, there is a feeding tray 4 for placing bearings and a second moving mechanism 5 for driving the feeding tray 4 to move back and forth. Above the second feeding trough 22, there is a clamping mechanism 6 for clamping the bearings located in the second feeding trough 22 and a third moving mechanism 7 for driving the clamping mechanism 6 to move left and right so that the clamping mechanism 6 places the clamped bearings on the feeding tray 4. Among them, at the starting end of the feeding track 2, there is a vibrating feeding tray that can convey the bearings into the first feeding trough 21. Beside the feeding tray 4, there is an injection molding device that can take out the bearings in the feeding tray 4 and is used for injection molding of the wheel hubs. In this way, after the bearings are sent from the first feeding trough 21 to the second feeding trough 22, the first moving mechanism 3 can move the bearings along the second feeding trough 22 from the left side to the right side. During this process, the subsequent bearings will also be sent from the first feeding trough 21 to the second feeding trough 22. Then, the clamping mechanism 6 is used to clamp the two bearings located in the second feeding trough 22. Then, the third moving mechanism 7 is used to move the clamping mechanism 6 above the feeding tray 4 and place the bearings on the feeding tray 4. Then, the second moving mechanism 5 moves the feeding tray 4 to the corresponding position for the injection molding device to grab and inject, thus realizing the fast and continuous transfer of bearings from feeding to injection molding and improving the production efficiency. At the same time, the height of the side wall of the second feeding trough 22 is set lower than that of the side wall of the first feeding trough 21, which is beneficial for the clamping mechanism 6 to clamp the bearings located in the second feeding trough 22.

[0022] In this solution, a limiting mechanism 8 is provided in the second feeding trough 22 to limit the movement of the bearings entering it along the second feeding trough 22 to the right side. The limiting mechanism 8 includes a baffle 81 hinged on the front side wall of the second feeding trough 22 and a return spring 82 arranged between the baffle 81 and the front side wall of the second feeding trough 22. The baffle 81 has two position states. One is to form an angle with the side wall of the second feeding trough 22 to limit the movement of the bearings in the second feeding trough 22; the other is to be parallel to the side wall of the second feeding trough 22 to enable the bearings to move to the right side in the second feeding trough 22. In this way, the position of the bearings in the second feeding trough 22 is limited, which is beneficial for the clamping mechanism 6 to clamp them.

[0023] In this solution, a position sensor 9 for detecting bearings is provided on the right side of the second feeding chute 22 to detect the bearings. When no bearing is detected, the first moving mechanism 3 is controlled to move the bearing along the second feeding chute 22 from the left side to the right side. When a bearing is detected, the clamping mechanism 6 is controlled to clamp the bearing located in the second feeding chute 22.

[0024] In this solution, an opening groove 23 is provided on the bottom wall of the second feeding chute 22. The first moving mechanism 3 includes a first telescopic cylinder 31 arranged below the second feeding chute 22 and a first linear module 32 for driving the first telescopic cylinder 31 to move left and right. The output end of the first telescopic cylinder 31 passes through the opening groove 23 and extends into the second feeding chute 22. When the first moving mechanism 3 works, the first telescopic cylinder 31 retracts its output end so that it does not extend out of the opening groove 23, and then moves to the left through the first linear module 32. Then the first telescopic cylinder 31 extends its output end so that it extends out of the opening groove 23. At this time, the output end of the first telescopic cylinder 31 is also located in the central hole of the bearing. Then the bearing is moved from the left side to the right side along the opening groove 23 through the first linear module 32. During this process, the bearing presses down the baffle 81. After the bearing passes, the baffle 81 is reset due to the reset spring 82, thereby moving the bearing to the right side of the second feeding chute 22. Further, the number of the feeding tracks 2 is two, the number of the second feeding chutes 22 corresponds to the number of the feeding tracks 2 and they are both located above the first linear module 32. A moving plate 33 is drivingly connected to the first linear module 32. The number of the first telescopic cylinders 31 corresponds to the number of the second feeding chutes 22 and they are all arranged on the moving plate 33. Thus, one first linear module 32 is used to drive two first telescopic cylinders 31 to move simultaneously to optimize the structure and make it simpler.

[0025] In this solution, the clamping mechanism 6 includes a fixing plate 61 arranged above the second feeding chute 22, a clamping cylinder 62 arranged on the fixing plate 61 for clamping the bearing located in the second feeding chute 22, and a second telescopic cylinder 63 arranged on the fixing plate 61 for driving the clamping cylinder 62 to move up and down. Thus, the second telescopic cylinder 63 is used to drive the clamping cylinder 62 to move up and down to clamp the bearing located in the second feeding chute 22 and place it on the feeding tray 4. Further, a sliding plate 64 that moves up and down along the surface of the fixing plate 61 is provided on the fixing plate 61. The clamping cylinder 62 is arranged on the lower side of the sliding plate 64. The extending end of the second telescopic cylinder 63 is connected to the upper side of the sliding plate 64. A guiding pair is arranged between the sliding plate 64 and the fixing plate 61. The guiding pair includes a guide rail 65 arranged on the fixing plate 61 and a guiding groove 66 arranged on the sliding plate 64 and cooperating with the guide rail 65.

[0026] In this solution, the third moving mechanism 7 includes a gantry 71 disposed on the workbench 1, and a third linear module 72 disposed on the gantry 71 and driving the fixing plate 61 to move left and right, so as to move the clamping mechanism 6 above the feeding tray 4.

[0027] In this solution, the second moving mechanism 5 includes a second linear module 51 disposed on the workbench 1 and driving the feeding tray 4 to move back and forth, so as to move the feeding tray 4 to a corresponding position for the next step of work.

[0028] In this solution, the feeding tray 4 includes a plurality of positioning columns 41 for positioning the bearings, so as to ensure that the bearings can be neatly placed on the feeding tray 4, which is beneficial for the injection molding equipment to grab.

[0029] The working process of the transfer device includes the following steps:

[0030] Feeding stage: Under the inclination of the first feeding groove 21, the bearings slide down to the second feeding groove 22 by gravity. At this time, the baffle 81 of the limit mechanism 8 forms an angle with the side wall of the second feeding groove 22 under the action of the return spring 82, blocking the bearings from continuing to move to the right.

[0031] Transfer stage: After the position sensor 9 detects that there is a bearing in the second feeding groove 22, the control system sends a signal, the first telescopic cylinder 31 retracts, the first linear module 32 drives it to move to the left, and then the first telescopic cylinder 31 extends and inserts into the central hole of the bearing. The first linear module 32 drives the first telescopic cylinder 31 to move the bearing from the left to the right along the opening groove 23. The baffle 81 is pressed down during the movement of the bearing, and the baffle 81 returns to its original position under the action of the return spring 82. When the position sensor 9 does not detect the bearing, the above actions are repeated to continue transferring the bearing.

[0032] Clamping and transfer stage: When the position sensor 9 detects that there is a bearing in the second feeding groove 22, the control system controls the second telescopic cylinder 63 to drive the slide plate 64 to descend, so that the clamping cylinder 62 reaches the position of the bearing to clamp the bearing, and then the second telescopic cylinder 63 drives the slide plate 64 to rise. Then, the third linear module 72 drives the fixing plate 61 to drive the clamping mechanism 6 and the bearing to move to the right above the feeding tray 4.

[0033] Placement and feeding tray 4 movement stage: The second telescopic cylinder 63 drives the slide plate 64 to descend again, and places the bearing on the positioning column 41 of the feeding tray 4. Then, the second linear module 51 drives the feeding tray 4 to move forward to the grabbing position of the injection molding equipment, and the automatic docking device is docked with the injection molding equipment. The injection molding equipment grabs the bearing for injection molding, completing the entire bearing transfer and production process.

The technical scope of this invention is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
