Implementation Method

[0025] To make the objectives, technical means, and advantages of the embodiments of this application clearer, the technical means of the embodiments of this application will be clearly and completely described below in conjunction with the drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art to which this application pertains without creative effort are within the scope of protection of this application.

[0026] The following disclosure provides many different embodiments or examples for implementing different structures of this application. To simplify the disclosure of this application, specific examples of components and arrangements are described below. Of course, these are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0027] For ease of description, spatial relative terms may be used in the text to describe the relative positional relationship or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "upper," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or movement change, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented as "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0028] Currently, in the manufacturing process of electronic products, some processes still require workers to pick up materials 200 and transport them from one process to the next, where the production equipment picks up the materials 200 for assembly or further processing. As shown in Figure 1, the material 200 includes a housing 201 and a contour groove 202 located on one side of the housing 201. Due to the low accuracy of manually placing the material 200, it is not convenient to position the contour groove 202 of the material 200 subsequently, which affects the quality and efficiency of product processing. After long hours of work, workers are prone to fatigue, resulting in decreased work efficiency, which further affects the quality and efficiency of product processing.

[0029] In order to solve the technical problem that the material 200 needs to be picked up manually in the prior art, resulting in poor positioning accuracy and affecting the quality and efficiency of product processing, this application provides a mobile positioning carrier 100 and a conveying device, which can improve the positioning accuracy of the material 200 and realize the automated conveying of the material 200, thereby improving the quality and efficiency of product processing.

[0030] Figure 2 shows a mobile positioning carrier 100 provided in an embodiment of this application, including a frame 1, a positioning block 2, a pair of grippers 3, and a drive mechanism 4. The frame 1 includes a first platform 11 and a second platform 12 arranged opposite to each other. The side of the second platform 12 away from the first platform 11 is disposed on an external assembly line (not shown in the figure). The external assembly line drives the frame 1 to move from the material picking position to the material unloading position. The positioning block 2 is disposed on the side of the first platform 11 away from the second platform 12 and is used to position the material 200. The grippers 3 have a first end 31 and a second end arranged opposite to each other. 32. The first end 31 of the gripper 3 is disposed on the side of the second platform 12 facing the first platform 11; the drive mechanism 4 is located between the first platform 11 and the second platform 12. The drive mechanism 4 includes a drive member (not shown in the figure) and a transmission device connected thereto. The power output end of the transmission device is connected to the first end 31 of the gripper 3 so that the gripper 3 rotates relative to the second platform 12. The gripper 3 has a first position and a second position. In the first position, the second end 32 of the gripper 3 can rotate towards the first platform 11 to the second position to clamp the material 200.

[0031] For ease of understanding and explanation, the length direction of the first platform 11 is the X-axis shown in the figure, the width direction of the first platform 11 is the Y-axis shown in the figure, and the height direction of the first platform 11 is the Z-axis shown in the figure. It can be understood that the side of the second platform 12 facing away from the first platform 11 is set on the external assembly line. The external assembly line can drive the frame 1 from the material picking position to the material unloading position, or drive the frame 1 from the material unloading position to the material picking position. First, the external assembly line drives the frame 1 to the material picking position. The side of the material 200 with the contour groove 202 faces the first platform 11 and is placed on the first platform 11. The contour groove 202 of the material 200 is engaged with the positioning block 2 of the first platform 11, which can restrict the displacement of the material 200 in the X-axis and Y-axis and the rotation around the Z-axis, thereby achieving precise positioning of the material 200. Next, the drive unit drives the gripper 3 to rotate relative to the second platform 12 (rotate around the X-axis) through the transmission device. In the first position, the second end 32 of the gripper 3 can rotate towards the first platform 11, that is, the second ends 32 of the two grippers 3 move closer to each other until the second position is reached. At this point, the two grippers 3 can clamp the two sides of the material 200, thereby limiting the displacement of the gripper 3 in the Z-axis and preventing the material 200 from shaking during the conveying process, which would affect the positioning accuracy of the material 200. During the process of the frame 1 moving from the picking position to the unloading position, the gripper 3 and the positioning block 2 can ensure that the position between the material 200 and the first platform 11 remains unchanged, thereby ensuring the quality and efficiency of subsequent product processing. Compared with the prior art, the embodiments of this application can improve the positioning accuracy of the material 200, and at the same time realize the automated conveying of the material 200, thereby improving the quality and efficiency of product processing.

[0032] It should be noted that the driving component can be an existing motor to provide driving force to the transmission device, so that the gripper 3 can automatically switch between the first position and the second position under the transmission action of the transmission device. The circumference of the positioning block 2 is adapted to the circumference of the contour groove 202 of the material 200, thereby improving the positioning accuracy of the material 200.

[0033] In some embodiments, as shown in Figures 2 and 3, the transmission device includes a driving gear shaft 41 and a first driven gear shaft 42 that are meshed with each other, two second driven gear shafts 43 that are meshed with each other, and a pair of rotating shafts 44. The driving gear shaft 41, the first driven gear shaft 42, and the second driven gear shaft 43 are arranged sequentially along the axial direction of the rotating shaft 44 and are parallel to each other. The driving member is connected to the driving gear shaft 41. Specifically, a first gear 411 is provided on the driving gear shaft 41, a second gear 421 that meshes with the first gear 411 is provided on the first driven gear shaft 42, and a third gear 431 that meshes with each other is provided on each of the two second driven gear shafts 43. The third gear 431 that is closer to the first driven gear shaft 42 meshes with the second gear 421. The axial direction of the driving gear shaft 41 is parallel to the X-axis. The second driven gear shaft 43 and the rotating shaft 44 are staggered. The axis of the rotating shaft 44 is parallel to the Y-axis. The second driven gear shaft 43 and the rotating shaft 44 correspond one-to-one, and a transmission component 45 is provided between the second driven gear shaft 43 and the corresponding rotating shaft 44 to make the rotating shaft 44 rotate along its own axis. The gripper 3 and the rotating shaft 44 correspond one-to-one, and the first end 31 of the gripper 3 is connected to the corresponding rotating shaft 44. The driving component drives the driving gear shaft 41 to rotate. Through the transmission action of the first gear 411 and the second gear 421, the first driven gear shaft 42 is driven to rotate. Then, through the transmission action of the second gear 421 and the third gear 431, the second driven gear rotates. Under the linkage action of the transmission component 45, the rotating shaft 44 and the gripper 3, the second end 32 of the gripper 3 is driven to rotate, thereby clamping or releasing the material 200.

[0034] As shown in Figure 3, the transmission component 45 includes a worm 451 and a worm wheel 452 that are meshed together. The worm 451 is coaxially arranged with the second driven gear shaft 43 and is connected to the second driven gear shaft 43. The worm wheel 452 is sleeved on the circumference of the rotating shaft 44. The circumference of the rotating shaft 44 may be provided with a spline, and the worm wheel 452 may be provided with a keyway that mates with the spline. Through the transmission action of the worm 451 and the worm wheel 452, the rotation of the rotating shaft 44 is realized.

[0035] In some embodiments, as shown in FIG3, a support plate 111 is provided on the side of the first platform 11 facing the second platform 12. The driving gear shaft 41, the first driven gear shaft 42, and the second driven gear shaft 43 are all rotatably connected to the support plate 111 through bearings. By providing the support plate 111 and bearings, a stable supporting force can be provided to the driving gear shaft 41, the first driven gear shaft 42, and the second driven gear shaft 43, while improving the smoothness of the rotation of the driving gear shaft 41, the first driven gear shaft 42, and the second driven gear shaft 43.

[0036] In some embodiments, a limiting mechanism is provided between the first driven gear shaft 42 and the second platform 12. The limiting mechanism is used to limit the rotational stroke of the first driven gear shaft 42. The rotational stroke of the first driven gear shaft 42 is the number of rotations of the first driven gear shaft 42. By limiting the rotational stroke of the first driven gear shaft 42, the rotation angle of the gripper 3 can be limited. Optionally, the angle between the gripper 3 and the Z-axis is θ. In the first position, the angle θ between the gripper 3 and the Z-axis is 45°, and in the second position, the angle θ between the gripper 3 and the Z-axis is 0°.

[0037] As shown in Figures 4 and 5, the limiting mechanism includes a lever 422, a limiting rack 46, and a pair of limiting plates 47. The lever 422 is arranged radially along the first driven gear shaft 42 and is fixedly connected to the first driven gear shaft 42. The limiting rack 46 is slidably arranged on the side of the second platform 12 facing the first platform 11. The side of the limiting rack 46 away from the second platform 12 is provided with a plurality of first grooves 461. The end of the lever 422 away from the first driven gear shaft 42 can be inserted into any one of the first grooves 461 to move the limiting rack 46 back and forth relative to the second platform 12. The two limiting plates 47 are arranged opposite each other and are located at both ends of the limiting rack 46. The driving component can drive the drive gear shaft 41 to rotate clockwise or counterclockwise, thereby driving the first driven gear shaft 42 to rotate. When the first driven gear shaft 42 rotates in its own direction, it drives the lever 422 to insert into the first groove 461 of the limiting rack 46, and moves the limiting rack 46 back and forth relative to the second platform 12 until the end of the limiting rack 46 abuts against the limiting plate 47, the first driven gear shaft 42 stops rotating, and at this time the gripper 3 stops rotating.

[0038] A slide groove 121 is provided on the side of the second platform 12 facing the first platform 11, which is slidably connected to the limiting rack 46. The length direction of the slide groove 121 is staggered with the axial direction of the first driven gear shaft 42. By providing the slide groove 121, the smoothness of the sliding of the limiting rack 46 can be improved.

[0039] In some embodiments, as shown in Figures 4 and 6, a connecting plate 33 is provided at the first end 31 of the gripper 3. The connecting plate 33 is provided with a slot 331 for engaging with the rotating shaft 44, and a fastener is provided on the connecting plate 33. The fastener can be a bolt or a cotter pin. When a bolt is used, the fixed connection between the gripper 3 and the rotating shaft 44 can be achieved through the threaded connection between the bolt and the connecting plate 33. When a cotter pin is used, the slot 331 can be locked through the cotter pin, thereby achieving a fixed connection between the gripper 3 and the rotating shaft 44.

[0040] In some embodiments, as shown in FIG3, a buffer layer 34 is provided on the side of the second end 32 of the gripper 3 facing the first platform 11. The buffer layer 34 can be made of a material with a certain elasticity, such as TPE (Thermoplastic rubber), TPV (Thermoplastic Vulcanizate), TPO (Thermoplastic polyolefin), TPU (Thermoplastic polyurethanes), etc. The buffer layer 34 can improve the friction between the gripper 3 and the material 200 on the one hand, and avoid wear on the material 200 during clamping and conveying.

[0041] As shown in Figure 4, a second groove 122 is provided on the side of the second platform 12 near the gripper 3. When the gripper 3 is in the first position, the first end 31 of the gripper 3 abuts against the second groove 122. By providing the second groove 122, the gripper 3 can be limited.

[0042] In some embodiments, as shown in FIG7, a guide rail 123 is provided on the side of the second platform 12 away from the first platform 11. The length direction of the guide rail 123 is parallel to the axial direction of the rotating shaft 44. The frame 1 moves along the guide rail 123 to the material picking position or the material unloading position. The external production line can adopt existing belt conveyors, plate chain conveyors, roller conveyors, etc. The guide rail 123 can be connected to the conveyor rollers of belt conveyors, plate chain conveyors, or roller conveyors to play a guiding role, thereby improving the stability of the moving positioning carrier 100 in conveying the material 200.

[0043] As shown in Figure 7, the frame 1 has a material picking position and a material unloading position on both sides of its own moving direction. The second platform 12 is provided with a third groove 124 on the side near the material picking position. The third groove 124 can be set into a V-shape, trapezoidal shape, etc., and is not limited here. When the frame 1 moves to the material picking position, the third groove 124 abuts against the external blocking cylinder, thereby stopping the movement.

[0044] As shown in Figure 2, an information code 112 is provided on the side of the first platform 11 away from the second platform 12. The information code 112 can be an existing two-dimensional barcode, one-dimensional barcode, etc. When the frame 1 moves to the material picking position, the external barcode scanner can scan the information code 112 to obtain the material 200 information, and at the same time send a running signal to the drive component (motor), so that the drive component rotates in the forward direction. Under the transmission action of the transmission device, the second end 32 of the gripper 3 is driven to rotate away from the first platform 11 until the first position (both grippers 3 are in the open state).

[0045] As shown in Figure 2, in some embodiments, the frame 1 further includes multiple support members 13, which are correspondingly arranged at the four corners of the second platform 12. One end of each support member 13 is connected to the side of the first platform 11 facing the second platform 12, and the other end is connected to the side of the second platform 12 facing the first platform 11, thus forming an accommodating space between the first platform 11 and the second platform 12. The drive mechanism 4 is disposed within the accommodating space. The support member 13 can provide stable support to the first platform 11 while also saving the arrangement space of the entire mobile positioning vehicle 100. It should be noted that the shape of the support member 13 can be plate-shaped, rod-shaped, or column-shaped, and is not limited here.

[0046] This application embodiment also provides a conveying device, including the mobile positioning carrier 100 as described above. The working principle of this conveying device can be referred to the above embodiment of the mobile positioning carrier 100. By setting the mobile positioning carrier 100, the automated conveying of materials 200 can be realized, thereby improving the quality and efficiency of product processing.

[0047] In an optional embodiment, the operation of the conveying device is as follows:

[0048] Preparation: The frame 1 moves from the loading position to the unloading position along the guide rail 123 until the third groove 124 abuts against the external blocking cylinder, and the frame 1 stops moving. At this time, the frame 1 reaches the unloading position, and the external barcode scanner scans the information code 112 to obtain the material 200 information.

[0049] Material Picking: The drive unit rotates forward, driving the drive gear shaft 41 and the first driven gear shaft 42 to rotate. Under the linkage of the second driven gear shaft 43 and the rotating shaft 44, the gripper 3 rotates. The lever 422 on the first driven gear shaft 42 moves the limiting rack 46, which slides towards the material picking position until it abuts one of the limiting plates 47. The gripper 3 rotates from the second position to the first position, and the gripper 3 reaches the open state. The contour groove 202 of the material 200 is aligned with the positioning block 2 of the first platform 11, and the material 200 is placed on the first platform 11, as shown in Figure 8.

[0050] Clamping: The drive unit rotates in the opposite direction, driving the drive gear shaft 41 and the first driven gear shaft 42 to rotate. Under the linkage of the second driven gear shaft 43 and the rotating shaft 44, the gripper 3 is driven to rotate. The lever 422 on the first driven gear shaft 42 moves the limiting rack 46. The limiting rack 46 slides towards the material unloading position until it abuts against another limiting plate 47. The gripper 3 rotates from the first position to the second position and clamps the material 200.

[0051] Unloading: The frame 1 moves from the material picking position to the material position along the guide rail 123, and the equipment of the next process picks up the material 200 for product assembly or reprocessing.
