[0084] Some embodiments of the present application will be described in detail below with reference to the drawings.

[0085] Please refer to Figure 1 , the embodiment of the present application provides a flipping and positioning device 100 for driving a workpiece 200 to rotate. In this embodiment, the workpiece 200 is a U-shaped frame of a mobile phone, but is not limited thereto. Specifically, the flipping and positioning device 100 includes a carrier seat 10, a rotating mechanism 20, a pushing assembly 30, and a limiting assembly 40.

[0086] The rotating mechanism 20 includes a transmission assembly 21 and a plurality of rotating members 22 connected to the transmission assembly 21 and used for carrying the workpiece 200. The transmission assembly 21 is arranged on the bearing seat 10, and the plurality of rotating members 22 are arranged at intervals and are respectively rotatably arranged on the bearing seat 10. The pushing assembly 30 is arranged on the bearing seat 10 and connected to the transmission assembly 21, and is used to drive the transmission assembly 21 to drive the plurality of rotating members 22 to rotate simultaneously, so that the plurality of rotating members 22 drive the workpiece 200 to rotate a preset angle. In this embodiment, the preset angle is 90 degrees, but it is not limited thereto. The limiting assembly 40 includes a first limiting member 41 and a plurality of second limiting members 42. The first limiting member 41 is arranged on the bearing seat 10 and is located on one side of the plurality of rotating members 22. The plurality of second limiting members 42 are respectively arranged on the plurality of rotating members 22 and protrude from the corresponding rotating members 22. When the plurality of rotating members 22 drive the workpiece 200 to rotate within a preset angle range, the first limiting member 41 pushes the workpiece 200 on the adjacent rotating member 22 to move towards the rotating member 22, and the plurality of second limiting members 42 respectively push the workpiece 200 on the adjacent rotating members 22 to move towards the corresponding rotating members 22, so as to realize the automatic positioning of the workpiece 200 on the rotating members 22 during rotation. In this embodiment, the preset angle range is 65 degrees to 90 degrees, but it is not limited thereto.

[0087] Please refer to Figure 2 , the bearing seat 10 includes a bottom plate 11 and two side plates 12 vertically arranged on one side of the bottom plate 11. A plurality of connecting holes 121 are formed in each side plate 12, and the plurality of connecting holes 121 are equidistantly arranged in the first direction. The two ends of the rotating member 22 are respectively rotatably arranged in the connecting holes 121 of the two side plates 12. In this embodiment, the plurality of connecting holes 121 on the two side plates 12 are respectively arranged oppositely, the connecting holes 121 are counterbored holes, and the first direction is the X-axis direction.

[0088] Please refer to Figure 3, a receiving groove 221 for placing the workpiece 200 is formed on the rotating member 22. A first positioning surface 222 and a second positioning surface 223 for positioning the workpiece 200 are respectively provided on the bottom of the receiving groove 221 and one side wall of the receiving groove 221. In this embodiment, the rotating member 22 includes a bearing portion 224 and two rotating shafts 225. The two rotating shafts 225 are connected to both ends of the bearing portion 224 and are respectively rotatably arranged in the connecting holes 121 of the two side plates 12 of the bearing seat 10 through bearings 23. The receiving groove 221 is formed on the adjacent side surfaces of the bearing portion 224. The first positioning surface 222 and the second positioning surface 223 are both flat surfaces and are perpendicularly arranged. Wherein, the side surface of the workpiece 200 abuts against the first positioning surface 222, and the end surface of the workpiece 200 abuts against the second positioning surface 223. In this way, the contact area between the workpiece 200 and the bearing portion 224 can be increased, and the workpiece 200 can be prevented from shaking in the receiving groove 221. In this embodiment, the bearing portion 224 and the two rotating shafts 225 are of an integral structure. In this way, it is beneficial to ensure the coaxiality and improve the operation stability of the rotating mechanism 20.

[0089] The rotating mechanism 20 further includes two adjusting members 24. The adjusting members 24 are in a block shape. The two adjusting members 24 are arranged at intervals on the first positioning surface 222. A receiving cavity 241 for placing the workpiece 200 is formed between the two adjusting members 24. The distance between the two adjusting members 24 is adjustable. In this embodiment, the adjusting members 24 are fixed on the first positioning surface 222 by bolts. The size of the adjusting members 24 is adjustable. In this way, adjusting members 24 of different sizes can be fixed on the first positioning surface 222 to adjust the size of the receiving cavity 241, so as to adapt to workpieces 200 of different sizes.

[0090] The transmission assembly 21 includes a plurality of gears 211 and a rack 212. The plurality of gears 211 are arranged at intervals in the first direction and are respectively connected to the plurality of rotating members 22 in one-to-one correspondence; the rack 212 extends in the first direction and is slidably arranged on the bearing seat 10. The rack 212 meshes with the plurality of gears 211. The pushing assembly 30 is connected to the rack 212. The pushing assembly 30 is used to drive the rack 212 to move in the first direction and drive the plurality of gears 211 and the plurality of rotating members 22 to rotate simultaneously. In this way, by providing a rack 212 and a plurality of gears 211, the plurality of rotating members 22 and the plurality of workpieces 200 can be driven to rotate simultaneously.

[0091] In this embodiment, the distance between the respective rotating members 22 is W, the number of teeth of the gear 211 is Z, the module of the gear 211 is m, and the meshing phase difference of adjacent gears 211 with respect to their respective rotating members 22 is θ. The rotating mechanism 20 of this embodiment satisfies the relational expression: θ = [(W / πm) - int(W / mZ)] * 360 / Z. Generally, θ ≠ 0, that is, the phase difference between adjacent rotating members 22 and the gear 211 objectively exists. Since the phase difference between the rotating member 22 and the gear 211 will affect the efficiency, stability, and reliability of the mechanical transmission system, for this purpose, please refer to Figure 4 , a through hole 2111 is formed in each gear 211. One end of each rotating member 22 extends into the through hole 2111 formed in the corresponding gear 211. The transmission assembly 21 further includes a plurality of abutting members 213 and a plurality of fixing members 214. The plurality of abutting members 213 correspond to the plurality of gears 211 one by one. Each abutting member 213 includes an abutting portion 2131 and a connecting portion 2132. One end of the abutting portion 2131 extends into the through hole 2111 and abuts against the hole wall of the through hole 2111 and the rotating member 22 respectively. The connecting portion 2132 is connected to the other end of the abutting portion 2131 and is located on one side of the gear 211. The plurality of fixing members 214 correspond to the plurality of gears 211 one by one. Each fixing member 214 passes through the connecting portion 2132 and the gear 211 respectively to fixedly connect the connecting portion 2132 and the gear 211. In this embodiment, the abutting member 213 is of a T-shaped structure. The fixing member 214 is a bolt. In this way, the connection between the connecting portion 2132 and the gear 211 can be realized.

[0092] Furthermore, please refer to Figure 5 , the hole wall of the through hole 2111 has an inner conical surface 2112. A sleeve hole 2133 for sleeving the corresponding rotating member 22 is formed at one end of the abutting portion 2131 away from the connecting portion 2132. The outer periphery of the abutting portion 2131 has an outer conical surface 2134 with a taper adapted to that of the inner conical surface 2112. At least one slot 2135 is formed at one end of the abutting portion 2131 of the rotating mechanism 20 away from the connecting portion 2132. In this way, when the abutting portion 2131 is subjected to an external force, it can contract inward and press the rotating member 22. Since the outer conical surface 2134 on the outer periphery of the abutting portion 2131 is adapted to the taper of the inner conical surface 2112 of the hole wall of the through hole 2111, the abutting portion 2131 has a good pressing effect on the rotating member 22.

[0093] In this way, through the above connection method, the circumferential connection between the gear 211 and the rotating member 22 can be realized, and the function of adjusting the phase of the gear 211 can be achieved, solving the phase difference problem faced by multiple gears 211 meshing with the same rack 212.

[0094] The pushing assembly 30 includes a floating joint 31 and a pushing drive member 32. One end of the floating joint 31 is connected to the rack 212; the pushing drive member 32 is disposed on the carrier seat 10 and connected to the other end of the floating joint 31. The pushing drive member 32 drives the rack 212 to move in the first direction through the floating joint 31. In this embodiment, the pushing drive member 32 is a cylinder. Thus, by providing the floating joint 31, the deviation of the rack 212 in its axial and / or radial directions can be reduced to reduce mechanical stress and vibration.

[0095] Furthermore, the pushing assembly 30 further includes a connecting plate 33, a buffering and impact-blocking member 34 and two buffer members 35. The connecting plate 33 extends in the first direction and is slidably disposed on the slide rail 36 on the carrier seat 10. The connecting plate 33 is connected to one side of the rack 212 and is connected to the pushing drive member 32. An avoidance hole 331 is formed on the side of the connecting plate 33 away from the rack 212; the buffering and impact-blocking member 34 is in a block shape and is disposed on the carrier seat 10 and located in the avoidance hole 331; the two buffer members 35 are disposed on the connecting plate 33 and located on the opposite sides of the buffering and impact-blocking member 34. The buffer members 35 are used to move along with the connecting plate 33 and abut against the side surface of the buffering and impact-blocking member 34. In this embodiment, the buffer members 35 are buffers. Thus, by providing the buffering and impact-blocking member 34 and the two buffer members 35, within the range at both ends of the two buffer members 35, the buffering and impact-blocking member 34 can play a role in buffering impact and decelerating, thereby limiting the rotation angle of the rotating member 22 and the workpiece 200.

[0096] Please refer to Figure 1 , both the first limiting member 41 and the second limiting member 42 are in a block shape. A pushing arc surface 421 for abutting and pushing the workpiece 200 is provided on one side of each of the first limiting member 41 and the second limiting member 42. Thus, the workpiece 200 can be gently abutted and pushed by the first limiting member 41 and the second limiting member 42.

[0097] In this embodiment, when the workpiece 200 is placed in the rotating member 22, it is in a vertical posture. After the rotating member 22 rotates 90 degrees, the workpiece 200 becomes in a horizontal posture. Due to the existence of rotational centrifugal force, during the rotation of the rotating member 22, the workpiece 200 will move away from the rotating member 22. Currently, the workpiece 200 after rotation is mainly repositioned by driving a push plate with a cylinder to push the workpiece 200, but this method is not allowed in terms of space. This embodiment utilizes the rotation characteristics of adjacent rotating members 22. With the second limiting member 42 fixed on the rotating member 22 being screwed out as the rotation angle increases, without adding power and mechanisms at the rotation end (the section where the rotating member 22 rotates from 65 degrees to 90 degrees), the automatic precise positioning and limiting function of the workpiece 200 during rotation is realized, saving space.

[0098] The flipping and positioning device 100 further includes a sensing member 50. The sensing member 50 is arranged on the bearing seat 10 through a connecting block 60 and is disposed close to the rotating member 22, and is used to detect whether there is a workpiece 200 on the rotating member 22 and whether the workpiece 200 on the rotating member 22 is warped. In this embodiment, there are two connecting blocks 60 which are arranged at intervals along the first direction on both sides of the plurality of rotating members 22. The sensing members 50 on the two connecting blocks 60 are two groups. One group is used to detect whether there is a workpiece 200 on the rotating member 22, and the other group is used to detect whether the workpiece 200 on the rotating member 22 is warped. The sensing member 50 is a photoelectric sensor.

[0099] The implementation process of the flipping and positioning device 100 provided by the embodiment of the present utility model is as follows:

[0100] Push the driving member 32 to drive the rack 212 to move along the first direction through the floating joint 31. The rack 212 moves along the first direction and drives the plurality of gears 211 and the plurality of rotating members 22 to rotate simultaneously, so that the rotating member 22 drives the workpiece 200 to rotate a preset angle. Please refer to Figures 6 to 8 , in Figure 6 , the rotating member 22 drives the vertically placed workpiece 200 to rotate 65 degrees to the right. In Figure 7 , the rotating member 22 drives the vertically placed workpiece 200 to rotate 80 degrees to the right. In Figure 8 , the rotating member 22 drives the vertically placed workpiece 200 to rotate 90 degrees to the right. During the process that the rotating member 22 drives the workpiece 200 to rotate 90 degrees from the vertical state, the pushing arc surfaces 421 of the first limiting member 41 and the second limiting member 42 can push the plurality of workpieces 200 to move towards the corresponding rotating members 22 to limit the positions of the workpieces 200 on the rotating members 22.

[0101] For the above flipping and positioning device 100, a pushing assembly 30 drives a transmission assembly 21 to drive the plurality of rotating members 22 to rotate simultaneously, so that the rotating member 22 drives the workpiece 200 to rotate a preset angle for processing the plurality of workpieces 200. The flipping of the plurality of rotating members 22 is realized by a single power, and the synchronous action can be carried out in a dense and small pitch. The structure is simple and the cost is low. And during the process that the rotating member 22 drives the workpiece 200 to rotate a preset angle, the workpiece 200 will move on the rotating member 22 under the action of centrifugal force. By the first limiting member 41 pushing the workpiece 200 on a nearby rotating member 22 to move towards the rotating member 22, and the plurality of second limiting members 42 respectively pushing the workpieces 200 on the adjacent rotating members 22 to move towards the corresponding rotating members 22, the automatic positioning of the workpiece 200 on the rotating member 22 during rotation can be realized, the positioning accuracy is high, and no additional mechanism is required for post-flipping positioning.

[0102] The flipping and positioning device 100 provided by the embodiment of the present application converts a linear motion into the rotation of multiple rotating members 22 through the transmission of a gear 211 and a rack 212, and a single power source can achieve the synchronous flipping and self-positioning of multiple rotating members 22; the rotating members 22 are integrally designed, without complex assembly and coaxial debugging, which is beneficial to obtaining coaxiality and improving the operating stability of the rotating mechanism 20, and reducing maintenance; an adjusting member 24 is arranged in the accommodating groove 221 of the rotating member 22, and by replacing adjusting members 24 of different specifications, it can adapt to the positioning of workpieces 200 of different sizes; the keyless connection between the gear 211 and the rotating member 22 solves the problems of rack 212 meshing and the phase difference of each rotating member 22.

[0103] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and not to limit them. Although the present application has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present application can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present application.
