However, the workpiece needs to be positioned and turned over in turn, which leads to the increase of the overall operation procedure of workpiece, reduces the turnover positioning efficiency. SUMMARY

[0003] In view of the above situation, it is necessary to provide a turnover positioning device to improve the turnover positioning efficiency of workpiece.

[0004] The application embodiment provides a turnover positioning device, which comprises:

[0006] A driving assembly comprising a driving member and a rotating member, the driving member is arranged on the base and connected with the rotating member, and the driving member is used for driving the rotating member to rotate along a preset direction;

[0007] A guide member connected with the base and having an avoiding hole, the avoiding hole accommodates the rotating member, opposite sides of the guide member are respectively provided with a guide curved surface and a fixed plane, the guide curved surface and the fixed plane are arranged around the avoiding hole, and the distance between the guide curved surface and the fixed plane decreases along the preset direction; and

[0008] The positioning assembly comprises a carrier, a clamping piece, a resisting piece, a movable piece and an elastic piece. The carrier is located on opposite sides of the guide curve with the fixed plane. The carrier is rotationally connected with the rotating piece. The carrier has a carrier body for carrying a workpiece. The clamping piece and the resisting piece are arranged around the carrier body. The clamping piece is movably arranged in the carrier. The resisting piece is arranged in the carrier. One end of the movable piece is movably arranged in the carrier along the guide curve and is arranged on a side of the clamping piece away from the guide curve and abuts against the clamping piece. The movable piece is provided with a resisting groove for receiving the resisting piece. The other end of the movable piece extends out of the carrier and is provided with a guide body abutting against the guide curve. The guide body is used to drive the carrier and the workpiece to synchronously rotate along a predetermined direction under the guidance of the guide curve.

[0055] Please refer to Figure 3 , Figure 4 and Figure 5 In some embodiments, the bearing part 41 further comprises a support body 412 and a connecting body 413. The support body 412 is connected with the rotating part 22 and is provided with a mounting groove 4121, a receiving groove 4122 and a containing groove 4123. The mounting groove 4121 penetrates through the support body 412 and is used for arranging the bearing body 411. The receiving groove 4122 and the containing groove 4123 are respectively communicated with the mounting groove 4121. The receiving groove 4122 is arranged in the direction in which the guide curved surface 32 points to the fixed plane 33. The containing groove 4123 is perpendicular to the extension direction of the receiving groove 4122. The receiving groove 4122 and the containing groove 4123 are respectively used for containing the clamping part 42 and the abutting part 43.

[0056] In this way, the bearing body 411, the clamping part 42 and the abutting part 43 are respectively contained in the mounting groove 4121, the receiving groove 4122 and the containing groove 4123, and the movable part 44 is contained in the active groove 4131, so that the bearing part 41, the clamping part 42, the abutting part 43 and the movable part 44 can be reasonably arranged, and the smooth operation of the positioning assembly 40 can be facilitated.

[0057] Please refer to Figure 4 In some embodiments, the clamping part 42 comprises a clamping body 421, a first elastic body 422 and an abutting body 423. The clamping body 421 is slidingly arranged in the receiving groove 4122 and extends out of the receiving groove 4122. The two ends of the first elastic body 422 are respectively elastically abutted against the clamping body 421 and the groove wall of the receiving groove 4122. The abutting body 423 is connected with the clamping body 421 and extends to the active groove 4131. The side of the abutting body 423 away from the guide curved surface 32 is abutted against the movable part 44. The abutting body 423 is used for driving the clamping body 421 to move close to the bearing body 411 under the drive of the movable part 44, so that the clamping body 421 clamps the workpiece 200 to the bearing body 411 and compresses the first elastic body 422 to the groove wall of the receiving groove 4122. Illustratively, the first elastic body 422 can be a spring.

[0058] Thus, by setting the specific structure of the clamping member 42, when the workpiece 200 is positioned, the movable member 44 pushes the abutting body 423 to drive the clamping body 421 to move close to the carrier 411, so that the clamping body 421 clamps the workpiece 200 to the carrier 411 in the direction of the guide curved surface 32 pointing to the fixed plane 33, realizing the function of positioning the workpiece 200 in the direction of the guide curved surface 32 pointing to the fixed plane 33, when the movable member 44 drives the movable member 44 to reset to the initial position, the compressed first elastic body 422 drives the clamping body 421 and the abutting body 423 to reset, facilitating the clamping member 42 to clamp and position the workpiece 200 repeatedly.

[0059] Please continue to refer to Figure 4 In some embodiments, the abutting member 43 includes an abutting body 431, a second elastic body 432, and a pushing body 433. The abutting body 431 is slidingly arranged in the accommodating groove 4123 and extends out of the accommodating groove 4123, and the two ends of the second elastic body 432 are elastically abutted against the abutting body 431 and the groove wall of the accommodating groove 4123, respectively. One end of the pushing body 433 is connected with the abutting body 431, and the other end of the pushing body 433 extends to the movable groove 4131 and abuts against the inclined surface of the groove wall of the abutting groove 441, and the pushing body 433 drives the abutting body 431 to move close to the carrier 411 under the drive of the second elastic body 432, so that the abutting body 431 abuts against the workpiece 200 to the carrier 411. Exemplarily, the second elastic body 432 can be a spring.

[0060] Thus, by setting the specific structure of the clamping member 42, when the workpiece 200 is positioned, the movable member 44 pushes the abutting body 423 to drive the clamping body 421 to move close to the carrier 411, so that the clamping body 421 clamps the workpiece 200 to the carrier 411 in the direction of the guide curved surface 32 pointing to the fixed plane 33, realizing the function of positioning the workpiece 200 in the direction of the guide curved surface 32 pointing to the fixed plane 33, when the movable member 44 drives the movable member 44 to reset to the initial position, the compressed first elastic body 422 drives the clamping body 421 and the abutting body 423 to reset, facilitating the clamping member 42 to clamp and position the workpiece 200 repeatedly.

[0061] Please refer to Figure 4In some embodiments, the movable member 44 further comprises a movable body 442 and a protruding body 443. The movable body 442 movably passes through the movable slot 4131 and is provided with an abutting groove 441 and a pushing groove 4421. The abutting groove 441 is arranged on the side of the movable body 442 facing the abutting member 43. The pushing groove 4421 is arranged on the side of the movable body 442 facing the clamping member 42 and accommodates one end of the clamping member 42 adjacent to the movable body 442. One end of the movable body 442 adjacent to the guide member 30 is connected with a guide body 444. The protruding body 443 protrudes from the side wall of the movable body 442 and is located between the connecting body 413 and the guide curve 32. The protruding body 443 and the connecting body 413 abut the two ends of the elastic member 45, respectively.

[0062] In this way, by arranging the abutting groove 441 and the pushing groove 4421 on different positions of the movable body 442, the movable body 442 can abut the abutting member 43 and the clamping member 42 through the abutting groove 441 and the pushing groove 4421, respectively. This facilitates the movable body 442 to drive the clamping member 42 and the abutting member 43 to move synchronously, so as to clamp and position the workpiece 200 in two directions at the same time. In addition, by arranging the protruding body 443 and the connecting body 413 to abut the two ends of the elastic member 45, respectively, the elastic member 45 can stably provide elastic force when positioning the workpiece 200, so as to drive the protruding body 443 to drive the movable body 442 to move towards the fixed plane 33, and then drive the movable body 442 to drive the clamping member 42 and the abutting member 43 to move synchronously.

[0063] Please refer to Figure 3 and Figure 4 In some embodiments, the connecting body 413 is further provided with a limiting slot 4132. The limiting slot 4132 is arranged on the side of the connecting body 413 facing the guide curve 32, and the elastic member 45 is arranged in the limiting slot 4132. The movable member 44 further comprises a limiting body 445. One end of the limiting body 445 is connected with the protruding body 443, and the other end of the limiting body 445 movably passes through the elastic member 45 and extends into the limiting slot 4132.

[0064] In this way, by arranging the limiting slot 4132 to accommodate the elastic member 45 and arranging the limiting body 445 to movably pass through the elastic member 45, the limiting slot 4132 and the limiting body 445 can limit the elastic member 45, so that the elastic member 45 is always compressed or elongated in the direction in which the guide curve 32 points to the fixed plane 33. In this way, the elastic member 45 can stably provide elastic force in the direction in which the guide curve 32 points to the fixed plane 33.

[0065] Please refer to Figure 3 and Figure 4In some embodiments, the connecting body 413 is further provided with a receiving groove 4133 in communication with the mounting groove 4121, and the carrier 411 comprises a bearing portion 4111, a first reference portion 4112, a second reference portion 4113, and an elastic portion 4114. The connecting body 413 is further provided with the receiving groove 4133 which is formed on the side of the connecting body 413 facing the support body 412 and in communication with the mounting groove 4121. The carrier 411 comprises the bearing portion 4111, the first reference portion 4112, the second reference portion 4113, and the elastic portion 4114. One end of the bearing portion 4111 is movably arranged in the mounting groove 4121 and used for bearing the workpiece 200, and the other end of the bearing portion 4111 is arranged in the receiving groove 4133 and used for abutting against the side of the support body 412 facing the connecting body 413. The first reference portion 4112 and the second reference portion 4113 are both protruded on the side of the bearing portion 4111 away from the connecting body 413 and correspond to the clamping member 42 and the abutting member 43 respectively, and the first reference portion 4112, the second reference portion 4113, the clamping member 42, and the abutting member 43 surround to form a clamping position 4113a for clamping the workpiece 200. The two ends of the elastic portion 4114 elastically abut against the groove bottom of the receiving groove 4133 and the bearing portion 4111 respectively. Exemplarily, the elastic portion 4114 can be a spring.

[0066] In this way, by protruding the first reference portion 4112 and the second reference portion 4113 on the bearing portion 4111 and corresponding to the clamping member 42 and the abutting member 43 respectively, the first reference portion 4112, the second reference portion 4113, the clamping member 42, and the abutting member 43 surround to form the clamping position 4113a for stably clamping and positioning the workpiece 200 to the preset position of the bearing portion 4111, thereby achieving accurate positioning of the workpiece 200. In addition, by elastically abutting the two ends of the elastic portion 4114 against the groove bottom of the receiving groove 4133 and the bearing portion 4111 respectively, during the process of placing the workpiece 200 on the bearing portion 4111, the workpiece 200 is pressed against the bearing portion 4111 under the action of an external force to compress the elastic portion 4114, so that the carrier 411 flexibly receives the workpiece 200, thereby avoiding damage to the workpiece 200.

[0067] Referring to Figure 4 In some embodiments, the bearing portion 4111 is provided with a suction hole 4111a which is arranged in the clamping position 4113a and in communication with an external air source, and the suction hole 4111a is used for suctioning the workpiece 200.

[0068] In this way, the workpiece 200 is suctioned by the suction hole 4111a under the conduction of the external air source, so that the workpiece 200 is stably positioned to the clamping position 4113a, thereby preventing the workpiece 200 from being separated from the bearing portion 4111 during the overturning process.

[0069] Referring to Figure 6In some embodiments, the base 10 comprises a first substrate 11, a second substrate 12 and a bearing 13. One side of the first substrate 11 is connected with the driving member 21, and the other side of the first substrate 11 is connected with the guide member 30. The second substrate 12 is arranged in parallel with the guide member 30 and is connected with the first substrate 11. The bearing 13 is embedded in the second substrate 12, and the rotating member 22 is movably arranged in the bearing 13. For example, the bearing 13 can be a bearing.

[0070] In this way, by arranging the two sides of the first substrate 11 to be connected with the driving member 21 and the guide member 30 respectively, and arranging the second substrate 12 to be arranged on the same side of the first substrate 11 as the guide member 30, the components in the turnover positioning device 100 can be reasonably arranged. In addition, by arranging the rotating member 22 to be movably arranged in the bearing 13, the rotating member 22 is prevented from directly contacting the second substrate 12, which is conducive to the rotating member 22 smoothly driving the carrier 41 to rotate.

[0071] For example, Figure 1 In some embodiments, the number of the guide members 30 and the positioning assemblies 40 is plural. The plurality of guide members 30 are arranged in parallel with the fixed plane 33 along the guide curved surface 32. The plurality of positioning assemblies 40 are arranged in one-to-one correspondence with the plurality of guide members 30 and are connected with the rotating member 22. In this way, the turnover positioning operation can be performed on a plurality of workpieces 200 at the same time, and the turnover positioning efficiency is improved.

[0072] It can be understood that the guide member 30 farthest from the driving member 21 is embedded with a rolling bearing. The rolling bearing and the driving member 21 are connected with the two ends of the rotating member 22 respectively, so as to stably support the rotating member 22, and further ensure the stable rotation of the rotating member 22.

[0073] For example, Figure 1 In some embodiments, the driving member 21 comprises a driving body 211, a driving body 212, a driven body 213 and a belt body 214. The driving body 211 is connected with the base 10. The driving body 212 is connected with the driving body 211. The driving body 211 drives the driving body 212 to rotate in a predetermined direction. The driven body 213 is arranged in parallel with the driving body 212 and is connected with the rotating member 22. The belt body 214 is sleeved on the driving body 212 and the driven body 213. The belt body 214 is used to drive the driven body 213 and the rotating member 22 to rotate synchronously under the driving of the driving body 212. For example, the driving body 211 can be a motor, the driving body 212 can be a driving wheel, the driven body 213 can be a driven wheel, and the belt body 214 can be a transmission belt.

[0074] Therefore, by setting the specific structure of the driving member 21, the driving body 211, the driving body 212, the driven body 213 and the belt body 214 can constitute a belt transmission mechanism, so that the driving member 21 can stably drive the rotating member 22 to rotate by the stable transmission characteristics of the belt transmission mechanism, while avoiding the driving member 21 occupying too large installation space in the direction in which the guide curved surface 32 points to the fixed plane 33, which is conducive to the application of the turnover positioning device 100 in narrow working space.

[0075] The turnover positioning device 100 described above, when working, first places the workpiece 200 on the bearing part 4111, then the suction hole 4111a adsorbs the workpiece 200 to the bearing part 4111, and then the driving member 21 drives the rotating member 22 to drive the bearing 41 to rotate along the preset direction, and the guide body 444 guides the movable body 442 to rotate along the preset direction under the guidance of the guide curved surface 32. Because the distance between the guide curved surface 32 and the fixed plane 33 decreases along the preset direction, the resistance applied by the guide curved surface 32 to the movable body 44 decreases, so that the elastic member 45 drives the protruding body 443 to drive the movable body 442 to move close to the fixed plane 33 during the rotation along the preset direction, and then the movable body 442 drives the clamping body 421 and the resisting body 431 to move close to the first reference part 4112 and the second reference part 4113 respectively, so as to realize the positioning of the workpiece 200 to the bearing part 4111, and the bearing 41 drives the positioned workpiece 200 to turn over to the preset orientation along the preset direction. The positioning and turnover of the workpiece 200 are completed at one time by using a single power source, which improves the turnover positioning efficiency of the workpiece 200.

[0076] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and are not limited. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present application.
