[0036] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying 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 without creative effort are within the scope of protection of this application.

[0037] The following disclosure provides numerous different embodiments or examples for implementing various structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. 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.

[0038] For ease of description, spatial relative terms may be used in the text to describe the relative position 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," "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 change of motion, 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 "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.

[0039] Currently, in the manufacturing process of electronic products, some steps still require workers to pick up material 200 and transport it from one step to the next, where the production equipment in the next step picks up material 200 for assembly or further processing. For example... Figure 1 As shown, the material 200 includes a housing 201 and a contour groove 202 disposed on one side of the housing 201. Due to the low accuracy of manual placement of the material 200, the contour groove 202 is not convenient for subsequent positioning of the material 200, which affects the quality and efficiency of product processing. After long-term operation, workers are prone to fatigue and reduced work efficiency, which further affects the quality and efficiency of product processing.

[0040] To address the technical problem in the prior art where manual picking of materials 200 is required, 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 materials 200 and realize the automated conveying of materials 200, thereby improving the quality and efficiency of product processing.

[0041] Figure 2 A mobile positioning carrier 100 provided in this application embodiment includes 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), and 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 32 arranged opposite to each other, and grip... The first end 31 of the claw 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 claw 3 so that the claw 3 rotates relative to the second platform 12. The claw 3 has a first position and a second position. In the first position, the second end 32 of the claw 3 can rotate towards the first platform 11 to the second position to clamp the material 200.

[0042] 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 second platform 12, on the side opposite to the first platform 11, is located on an external assembly line. The external assembly line can move the frame 1 from the material picking position to the material unloading position, or vice versa. First, the external assembly line moves the frame 1 to the material picking position. The material 200, with the contour groove 202 facing the first platform 11, is placed on the first platform 11. The contour groove 202 of the material 200 engages with the positioning block 2 of the first platform 11, which restricts the displacement of the material 200 along the X and Y axes and its 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) via 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.

[0043] It should be noted that the driving component can use 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.

[0044] In some embodiments, such as Figure 2 and Figure 3As shown, 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, the driving gear shaft 41 is provided with a first gear 411, the first driven gear shaft 42 is provided with a second gear 421 that meshes with the first gear 411, and the two second driven gear shafts 43 are respectively provided with third gears 431 that mesh with each other. The third gear 431 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 is rotated. 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.

[0045] like Figure 3 As shown, the transmission component 45 includes a worm gear 451 and a worm wheel 452 that mesh with each other. The worm gear 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 splines, and the worm wheel 452 may be provided with a keyway that mates with the splines. Through the transmission action of the worm gear 451 and the worm wheel 452, the rotation of the rotating shaft 44 is realized.

[0046] In some embodiments, such as Figure 3 As shown, 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 via bearings. By providing the support plate 111 and bearings, stable support 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 their rotation.

[0047] In some embodiments, a limiting mechanism is provided between the first driven gear shaft 42 and the second platform 12 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°.

[0048] like Figure 4 and Figure 5 As shown, 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 the two 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.

[0049] The second platform 12 has a slide groove 121 on the side 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 setting the slide groove 121, the smoothness of the sliding of the limiting rack 46 can be improved.

[0050] In some embodiments, such as Figure 4 and Figure 6 As shown, the first end 31 of the gripper 3 is provided with a connecting plate 33. The connecting plate 33 is provided with a slot 331 for engaging with the rotating shaft 44. Fasteners are provided on the connecting plate 33. The fasteners can be bolts or cotter pins. When bolts are used, the threaded connection between the bolts and the connecting plate 33 can achieve a fixed connection between the gripper 3 and the rotating shaft 44. When cotter pins are used, the slot 331 can be locked, thereby achieving a fixed connection between the gripper 3 and the rotating shaft 44.

[0051] In some embodiments, such as Figure 3As shown, 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, and also prevent wear on the material 200 during clamping and conveying.

[0052] like Figure 4 As shown, 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. The gripper 3 can be limited by the second groove 122.

[0053] In some embodiments, such as Figure 7 As shown, 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 axis 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 and improve the stability of the moving positioning carrier 100 in conveying the material 200.

[0054] like Figure 7 As shown, the frame 1 has a material pick-up position and a material unloading position on its two sides in its own moving direction. The second platform 12 is provided with a third groove 124 on the side near the material pick-up position. The third groove 124 can be set in a V-shape, trapezoidal shape, etc., and is not limited here. When the frame 1 moves to the material pick-up position, the third groove 124 abuts against the external blocking cylinder, thereby stopping the movement.

[0055] like Figure 2 As shown, 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 QR code, 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), causing the drive component to rotate forward. 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).

[0056] like Figure 2 As shown, 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 members 13 can provide stable support to the first platform 11 while also saving space in the overall arrangement of the 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.

[0057] This application 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, improving the quality and efficiency of product processing.

[0058] In an optional embodiment, the conveying device operates as follows:

[0059] Material preparation: The frame 1 moves along the guide rail 123 from the loading position to the picking position until the third groove abuts against the external blocking cylinder, and the frame 1 stops moving. At this time, the frame 1 reaches the picking position, and the external barcode scanner scans the information code 112 to obtain the material 200 information.

[0060] Material handling: 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 actuates the limiting rack 46, causing the limiting rack 46 to slide towards the material handling 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, such as... Figure 8 As shown.

[0061] 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 rotates. 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.

[0062] Material feeding: 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.
