Description

Technical Field

[0001] The utility model relates to the field of devices used in a wheel hub transfer process, in particular to a wheel hub transfer follower mechanism and a wheel hub transfer device. Background Art

[0002] After the production of automobile wheels is completed, they need to be subjected to processes such as powder spraying, drying, painting, and baking. After each process is completed, the wheel hub needs to be moved away from the processing area by a robotic arm. Since the robotic arm is set in a fixed position, a transfer device is required to transport the wheel hub away. Currently, a discharging column with conveyable movement is used on the market. The robotic arm clamps the processed wheel hub onto the discharging column, reducing the contact area between the wheel hub and the discharging column, thereby achieving the purpose of protecting the wheel hub. Specifically, the clamping assembly is driven by a synchronous belt, and the positioning, clamping, and transmission of the discharging column are achieved in conjunction with a photoelectric sensor. However, during use, it was found that the servo motor and synchronous belt often become out of sync. During operation, the information feedback from the photoelectric sensor must be met and the operation must be carried out, which will cause torque to be generated, resulting in the failure to meet the purpose of synchronous operation. In severe cases, it can also cause damage to the equipment. Therefore, there is an urgent need to provide a wheel hub rotation line follower mechanism and wheel hub rotation equipment to solve the above problems. Summary of the Invention

[0008] As a preferred structure of the present invention, the detection sensor includes a first photoelectric sensor and a second photoelectric sensor, the first photoelectric sensor and the second photoelectric sensor are oriented to the same side as the clamping assembly, and the first photoelectric sensor and the second photoelectric sensor are spaced apart.

[0014] Different from the existing technology, the above technical solution has the following beneficial effects:

[0015] The mechanism can effectively locate the position of the discharge column by setting a detection sensor. When the detection sensor detects the discharge column, the clamping assembly starts to work to clamp the discharge column to prevent the discharge column from tilting sideways when the wheel hub is placed on the discharge column. After clamping, the clamping assembly follows the discharge column to move along the slide until the clamping work is completed. The clamping assembly releases the discharge column. At this time, the drive motor works to drive the synchronous belt, thereby driving the drive block, so that the drive block drives the slide to reset to the starting position; this follower mechanism does not contact the synchronous belt and the drive block in the process of following the movement of the discharge column, thereby effectively avoiding the problem of the drive motor and the synchronous belt being out of synchronization, resulting in dislocation and damage to the equipment.

[0022] In order to explain the technical content, structural features, achieved objectives and effects of the technical solution in detail, the following is a detailed description in conjunction with specific embodiments and accompanying drawings.

[0023] like Figures 1 to 4 As shown, this embodiment provides a hub rotation tracking mechanism, including: a frame, a driving motor 101 and a synchronous wheel 102 are provided on the frame 1, a synchronous belt 103 is provided between the output end of the driving motor and the synchronous wheel, a driving block 104 is provided on the synchronous belt, a slide 2 is provided on one side of the synchronous belt along the movement direction of the synchronous belt, the driving block is linked to the slide 2, a clamping assembly 3 is provided on the slide 2, and a detection sensor 5 is provided on the frame along the movement direction of the synchronous belt.

[0024] In this embodiment, a detection sensor is set to detect the position of the discharge column in real time. The detection sensor can be a photoelectric sensor. In this embodiment, the photoelectric sensor can be set at the starting position where the clamping assembly starts clamping. In this way, when the discharge column 7 passes the starting position, the photoelectric sensor can immediately detect the discharge column, and the clamping assembly can now perform the clamping operation; after clamping, the clamping finger assembly follows the movement direction of the slide until the wheel hub is placed on the discharge column, and the clamping assembly releases the discharge column. At this time, the drive motor works to reset the clamping assembly on the slide to the starting position through the synchronous belt and the drive block. After the clamping assembly is reset, the drive block is separated from the slide and no longer driven, thereby avoiding deviation of the clamping assembly when the synchronous belt deviates; specifically, after the clamping assembly is reset to the starting position through the drive block, the drive motor and the synchronous belt work to reset the drive block in reverse to the starting position of the drive block, waiting for the next drive to reset the clamping assembly. In this embodiment, the driving motor can be a servo motor, and the output end of the driving motor is provided with a synchronous belt, so that it can realize synchronous movement with the synchronous wheel provided on the frame through the synchronous belt. The purpose of using the servo motor and the synchronous belt in this embodiment is to facilitate the control of the moving position of the driving block. Of course, in different embodiments, if other motors and transmission methods are used to achieve the reset of the clamping assembly, it should also be equivalent to the present solution.

[0025] like Figure 2 As shown, in this embodiment, the clamping assembly 3 includes a fixed plate 301 and a clamping jaw 302, the fixed plate is arranged on the slide, the clamping jaw 302 is arranged on the fixed plate 301, the slide 2 includes a first guide rail 201 and a slider 202, the clamping assembly 3 is arranged on the slider 202, and the slider 202 is adapted to the first guide rail 201; the clamping jaw 302 can adopt a hydraulic parallel clamping jaw; the first guide rail is used to provide a stable movement path for the slider, so that during the following process, there will be no problems of shaking, failure to follow, and offset of the clamping assembly.

[0026] like Figure 2 and Figure 3 As shown, a linkage block 401 is provided between the slider 202 and the clamping assembly 3, and the linkage block 401 is adapted to the drive block 104. Specifically, the linkage block 401 is provided with an extension portion 402, and a cam 105 is provided on the side of the drive block 104 near the extension portion 402, and the cam is adapted to the extension portion. When the clamping assembly needs to be reset, the drive motor drives the drive block close to the extension portion of the linkage block until the cam 105 contacts the extension portion. At this time, driven by the drive motor and the synchronous belt, the cam 105 can drive the extension portion to move, achieving the reset effect. The setting of the cam can effectively prevent scratches caused by hard direct contact and collision, and can also effectively provide an adjustment function during operation.

[0027] like Figure 2 and Figure 3 As shown, in order to further improve the stability of the driving block, in some embodiments, a second guide rail 106 is provided in the middle of the synchronous belt along the length direction of the synchronous belt, and the bottom of the driving block is adapted to the second guide rail 106 .

[0028] In the above embodiment, the detection sensor 5 includes a first photoelectric sensor 501 and a second photoelectric sensor 502. The first photoelectric sensor 501 and the second photoelectric sensor 502 are oriented on the same side as the clamping assembly, and the first photoelectric sensor and the second photoelectric sensor are arranged at intervals. In this embodiment, when the first photoelectric sensor detects the discharge column, the clamping assembly starts to clamp the discharge column. When the second photoelectric sensor detects the discharge column, the robotic arm starts to place the parts and follow. The two photoelectric sensors can further improve the discharge accuracy of the robotic arm.

[0029] like Figure 3 As shown, in different embodiments, the detection sensor also includes a third photoelectric sensor 503, the third photoelectric sensor is oriented on the same side as the clamping assembly, and the second photoelectric sensor is arranged between the first photoelectric sensor and the third photoelectric sensor; in this embodiment, the third photoelectric sensor is used to detect the discharge column, and when the discharge column clamped by the clamping assembly is detected, the clamping assembly is controlled to release the discharge column, and the driving block works to realize the resetting of the clamping assembly.

[0030] In the above embodiment, if Figure 3 As shown, the first photoelectric sensor is arranged at the starting position of the clamping finger assembly. In order to prevent the clamping assembly from crossing the starting position, in some embodiments, a limit member 601 is provided on the frame located on the side of the starting position of the clamping assembly, and the clamping assembly 3 is restricted to the starting position by the limit member 601.

[0031] like Figure 4 As shown, in certain embodiments, a wheel hub rotation device is further provided, comprising a conveyor assembly 8 and a discharge column 7, the discharge column being in driving connection with the conveyor assembly. A wheel hub rotation follower mechanism as described in any of the above embodiments is provided on one side of the discharge column. The clamping assembly and detection sensor are positioned toward the discharge column, and the slide is positioned along the transmission direction of the discharge column. In this embodiment, the discharge column 7 comprises a column 701 and a tray 702, which is fixedly mounted on the upper portion of the discharge column. The top end of the discharge column is adapted to fit within the axial center hole of the wheel hub.
