DETAILED DESCRIPTION

[0048] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. It should be understood that the following is only for illustration and not for limiting the present invention.

[0049] The object carrier 10 of the present application is used on a production line to carry workpieces and facilitate the flow of workpieces on a conveyor line. Figure 1-Figure 3 A loading tool 10 includes a support base 1, a positioning platform 2 and a rotating mechanism 3. The support base 1 is used to be placed on a conveyor chain 301 of a production line. The positioning platform 2 is rotatably connected to the support base 1. The positioning platform 2 can rotate relative to the support base 1. The positioning platform 2 is used to carry a workpiece to facilitate the processing of the workpiece.

[0050] At least part of the rotating mechanism 3 can drive the positioning platform 2 to rotate; the rotating mechanism 3 includes a rotating transmission component 31 and a rotating shaft 32; the rotating shaft 32 is fixed or limited or integrally formed with the positioning platform 2, the rotating shaft 32 drives the positioning platform 2 to rotate, and the rotating transmission component 31 can drive the rotating shaft 32 to move. In this way, since the object carrier 10 has a rotating mechanism 3, when an external force is applied to the rotating mechanism 3, the rotating transmission component 31 rotates under the action of the external force and drives the rotating shaft 32 to rotate, so that the positioning platform 2 can rotate. In this way, the positioning platform 2 can be automatically rotated under the external force, especially the external force applied by the machine, so that the object carrier 10 can be used in an automated production line.

[0051] In this article, the positioning table 2 refers to the part that carries the workpiece. In some embodiments, the positioning table 2 and the rotating shaft 32 are two parts, and the two are fixedly arranged, such as screws. In this embodiment, since the positioning table 2 and the rotating shaft 32 are two parts, the two can be formed by separate processing. The size of the rotating shaft 32 is less affected by the positioning table 2, and the thickness of the rotating shaft 32 can be relatively larger than the thickness of the positioning table 2. On the one hand, the rotating shaft 32 can be conducive to bearing rotation. On the other hand, the thickness of the positioning table 2 can be slightly thinner, which can not only reduce the magnitude of the rotational force received by the subsequent rotating mechanism 3, but also reduce the use of materials and reduce costs. In some embodiments, the rotating shaft 32 is formed integrally with the positioning table 2, for example, by processing a tooling plate of a certain thickness. In this way, the rotating shaft 32 is formed at the two ends of the positioning table 2 by mechanical processing. In this case, since the rotating shaft 32 needs to bear rotation, the thickness needs to be thicker, and the tooling plate thickness needs to be relatively thicker.

[0052] As a specific implementation method, refer to Figure 4 , the rotating shaft 32 and the positioning platform 2 are fixedly arranged, the first end 321 of the rotating shaft 32 has a limiting groove 322, a part of the positioning platform 2 is located in the limiting groove 322, and the positioning platform 2 and the rotating shaft 32 are fixed, for example, by screws. Along the thickness direction of the positioning platform 2, the thickness of the first end 321 of the rotating shaft 32 is greater than the thickness of the positioning platform 2, so that it is convenient for the bearing of the rotating shaft 32. In this way, the positioning platform 2 can be turned over by fixing the rotating shaft 32 and the positioning platform 2. In addition, by setting the limiting groove 322 on the rotating shaft 32, the positioning platform 2 can be stuck in the limiting groove 322, and then the positioning platform 2 and the rotating shaft 32 are fixed, so that a certain thickness of the positioning platform 2 can be set according to the actual workpiece requirements, so that the factors that need to be considered for the positioning platform 2 are relatively few, which is also convenient for the design of the positioning platform 2, and reduces the problem of increased cost of the positioning platform 2 caused by considering too many factors and requiring a larger thickness of the positioning platform 2.

[0053] More specifically, refer to Figure 1 and Figure 6The support seat 1 includes a base 11 and a side seat body 12. The first end 121 of the side seat body 12 is fixed to the base 11. The second end 122 of the side seat body 12 has a mounting hole 123. Part of the rotation shaft 32 is located in the mounting hole 123. The installation of the mounting hole 123 can facilitate the position determination of the positioning platform 2, and facilitate the positioning platform 2 fixed to the rotation shaft 32 to be supported on the side seat body 12, so that the positioning platform 2 can rotate relative to the side seat body 12.

[0054] Reference Figure 7 The rotating shaft 32 has a first connecting portion 323, a second connecting portion 324 and a third connecting portion 325. The second connecting portion 324 connects the first connecting portion 323 and the third connecting portion 325. The first connecting portion 323 is provided with a limiting groove 322. Along the thickness direction of the positioning platform 2, the thickness of the first connecting portion 323 is greater than the thickness of the positioning platform 2. The first connecting portion 323 is used to be fixed to the positioning platform 2. At least part of the second connecting portion 324 is located in the mounting hole 123. The third connecting portion 325 is used to be connected to the rotating transmission component 31. In this way, the third connecting portion 325 and the rotating transmission component 31 rotate synchronously, and the synchronous rotation of the positioning platform 2 can be realized.

[0055] As an embodiment, the rotating transmission component 31 includes a first gear 311, a second gear 312, an output shaft 313 and a transmission belt 314. The first gear 311 and the output shaft 313 are fixed, the first gear 311 and the second gear 312 are meshed, the transmission belt 314 and the second gear 312 are connected in transmission, and the transmission belt 314 can drive the rotating shaft 32 to rotate. By applying force to the output shaft 313 by external force, the output shaft 313 drives the first gear 311 to rotate, and then the transmission belt 314 drives the rotating shaft 32 to rotate. In this way, the hard connection of the rotating connection can be connected by a soft material such as the transmission belt 314, which is more conducive to providing a rotation margin, so that the position of the rotation can be more suitable for the subsequent rotation position, and can be adjusted even when there is a deviation.

[0056] Reference Figure 4 and Figure 5 The second gear 312 is located below the rotating shaft 32, the output shaft 313, the first gear 311 and the second gear 312 are located on one side of the side seat body 12, that is, the inner side of the cargo carrier 10, and the transmission belt 314 is located on the other side of the side seat body 12, which is more conducive to the compact structure size of the cargo carrier 10.

[0057] The rotating transmission component 31 has a driving wheel 315 and a driven wheel 316, the driving wheel 315 and the second gear 312 are coaxially arranged, and the second gear 312 can drive the driving wheel 315 to rotate, and the transmission belt 314 connects the driving wheel 315 and the driven wheel 316, and the driven wheel 316 and the rotating shaft 32 are coaxially arranged. In this way, the positioning platform 2 can be driven to rotate through the transmission belt 314.

[0058] Furthermore, the transmission belt 314 may also have a rack, which is connected to the driving wheel 315 and the driven wheel 316, so that the transmission belt 314 is not easy to slip, and the transmission belt 314 and the output shaft 313 rotate synchronously.

[0059] The cargo-carrying tool 10 may further include a tensioning wheel 4, which is disposed between the driving wheel 315 and the driven wheel 316. The position of the tensioning wheel 4 may be adjusted, and a portion of the transmission belt 314 is in contact with the tensioning wheel. Thus, by adjusting the position of the tensioning wheel, the transmission belt 314 between the driving wheel 315 and the driven wheel 316 may be effectively connected to reduce slippage.

[0060] The first end 3131 of the output shaft 313 has a shaft matching portion 3132, and the second end 3133 of the output shaft 313 is fixed to the first gear 311. As a specific implementation, the shaft matching portion 3132 can be a hexagonal structure, and the other end 3133 of the output shaft 313 is fixed to the first gear 311; in this way, when the external mechanism provides the output shaft 313 with a rotating force, the external mechanism can match the output shaft 313 with a hexagonal structure, and the external mechanism and the output shaft 313 with a hexagonal structure are sleeved, so that when the external mechanism rotates, it can drive the output shaft 313 to rotate. It should be understood that the hexagonal structure is only a specific implementation method, and the connection between the output shaft 313 and the external mechanism can also be various non-circular structures.

[0061] The base 11 has a shaft connection seat 111, and the shaft connection seat 111 has a connection hole 53112. At least part of the output shaft 313 is located in the connection hole 53112. The output shaft 313 is limited to the shaft connection seat 111, and the output shaft 313 can rotate relative to the shaft connection seat 111. The output shaft 313 and the shaft connection seat 111 are connected, for example, by a bearing. The shaft connection seat 111 can provide support for the output shaft 313, so that the position of the output shaft 313 is more accurate. Since the first end 3131 of the output shaft 313 is fixed to the first gear 311, the position of the first end is close to the projection position of the rotating shaft 32 toward the base 11, and the second end 3133 of the output shaft 313 needs to be connected to an external power machine, so the second end 3133 of the output shaft 313 is located to extend out of the base 11, and is used to cooperate with the external power machine, and the shaft connection seat 111 can play an effective supporting role.

[0062] In this embodiment, the output shaft 313 and the rotating shaft 32 are arranged perpendicularly, the axis of the first gear 311 of the cargo carrier 10 is perpendicular to the axis of the second gear 312, and the second gear 312 is in transmission connection with the transmission belt 314. The engagement of the second gear 312 and the first gear 311 can be used to change the rotation direction so that the rotation direction of the rotating shaft 32 is perpendicular to the rotation direction of the output shaft 313. This embodiment is arranged to adapt to the situation that the output shaft 313 and the rotating shaft 32 rotate in different directions.

[0063] More specifically, the carrier 10 is defined to have a length direction and a width direction, the positioning platform 2 is arranged along the length direction, and the rotating shaft 32 is located on both sides of the positioning platform 2 in the length direction. The output shaft 313 is arranged on one side of the width direction of the carrier 10, and the output shaft 313 is arranged perpendicular to the length direction. In this way, when the length direction is the conveying direction of the conveyor chain 301 below the carrier 10, by arranging the external mechanism connected to the output shaft 313 on one side of the width direction of the carrier 10, when necessary, it is matched with the output shaft 313 to provide rotational force, and when not needed, the external mechanism is on the side of the carrier 10, which is more conducive to the circulation of the carrier 10 on the conveyor chain 301.

[0064] As another embodiment, the object carrier 10 further includes a rotating disk 5, the rotating disk 5 and the positioning platform 2 are fixed or limited, and the rotating disk 5 can move together with the positioning platform 2. The object carrier 10 has a limiting column 6, the limiting column 6 and the support seat 1 are fixed; one of the rotating disk 5 and the limiting column 6 has a first limiting groove 51 and a second limiting groove 52, and the other of the rotating disk 5 and the limiting column 6 has a limiting head 61; the object carrier 10 has at least a first working state and a second working state, in the first working state, at least a part of the limiting head 61 is located in the first limiting groove 51, and in the second working state, at least a part of the limiting head 61 is located in the second limiting groove 52.

[0065] In this embodiment, when the positioning platform 2 rotates, the rotating disk 5 rotates synchronously, and the limiting head 61 can be located in the first limiting groove 51 or the second limiting groove 52. In this way, the rotation position can be limited while the positioning platform 2 rotates, reducing manual assistance and facilitating automation.

[0066] More specifically, the rotating disk 5 has a first limiting groove 51 and a second limiting groove 52, and the limiting column 6 has a limiting head 61. The rotating disk 5 can rotate relative to the limiting column 6. The rotating disk 5 is sleeved on the rotating shaft 32, and at least part of the second connecting portion 324 is located in the connecting hole 53112 of the rotating disk 5. The outer diameter of the second connecting portion 324 is smaller than that of the first connecting portion 323. The rotating disk 5 and the first connecting portion 323 are offset. Figure 6The rotating disk 5 is limited between the first connecting portion 323 and the side seat body 12 , and the rotating disk 5 can rotate synchronously with the rotating shaft 32 .

[0067] The rotating disk 5 has at least an arc-shaped peripheral wall 54, which connects the first limiting groove 51 and the second limiting groove 52, and the radius of the arc-shaped peripheral wall 54 is greater than the radius corresponding to the bottom wall of the first limiting groove 51, and the radius of the arc-shaped peripheral wall 54 is greater than the radius corresponding to the bottom wall of the second limiting groove 52. The limiting head 61 is a roller, and the roller can slide along the arc-shaped peripheral wall 54; in the first working state, at least part of the roller is located in the first limiting groove 51, and in the second working state, at least part of the roller is located in the second limiting groove 52. The provision of the arc-shaped peripheral wall is conducive to the guidance of the limiting head during the sliding process, so that the limiting head is more conducive to being limited in the first limiting groove and the second limiting groove.

[0068] The rotating disk 5 is generally semicircular in structure, and has a first limiting groove 51 and a second limiting groove 52. The loading tool 10 has a limiting column 6, and the limiting column 6 and the side seat 12 are fixedly arranged. The limiting head 61 is, for example, a roller. When the rotating disk 5 rotates to a limiting position, the roller of the limiting column 6 slides along the outer circumference of the rotating disk 5 to the first limiting groove 51, which can be used to limit the rotating disk 5 at one position. When the rotating disk 5 rotates to another limiting position, the roller of the limiting column 6 slides along the outer circumference of the rotating disk 5 to the second limiting groove 52, which can be used to limit the rotating disk 5 at another position. In this way, the positioning platform 2 can be limited at the position of flipping at different positions.

[0069] As another embodiment, the rotating disk 5 has a limiting head 61, and the limiting column 6 has a first limiting groove 51 and a second limiting groove 52. After the rotating disk 5 rotates, at one position, part of the limiting head 61 is located in the first limiting groove 51, and at another position, part of the limiting head 61 is located in the second limiting groove 52.

[0070] Reference Figure 8-Figure 9 As an embodiment, the carrier 10 also has a self-locking mechanism 7. The carrier 10 has the self-locking mechanism 7 and a rotating transmission component 31. The rotating transmission component 31 has a driving shaft 317. The self-locking mechanism 7 has a sliding component 71 and a limit pin 72. The limit pin 72 and the sliding component 71 are fixed or integrally arranged. The sliding component 71 has an external force matching portion 7111 for matching with an external force; the driving shaft 317 is connected to the positioning platform 2 in a transmission manner, and the driving shaft 317 can rotate synchronously with the positioning platform 2; the driving shaft 317 has a limit hole 3171, and the limit pin 72 and the limit hole 3171 are adapted to each other.

[0071] The sliding component 71 has at least a first position and a second position. In the first position, at least a portion of the limiting pin 72 is located in the limiting hole 3171 . In the second position, the limiting pin 72 is not located in the limiting hole 3171 .

[0072] In this way, the sliding component 71 can move under the action of external force. During the movement of the sliding component 71, at least a part of the limit pin 72 is located in the limit hole 3171. In the second position, the limit pin 72 is not located in the limit hole 3171, thereby enabling the position locking and unlocking of the driving shaft 317, and further facilitating the locking and unlocking of the rotational position of the positioning platform 2. In this way, this embodiment can be realized through automation.

[0073] The self-locking mechanism 7 has a slide rail 73, a limit pin 72 and a sliding member 71 are fixed or integrally arranged, and the slide rail 73 is located at the side seat body 12 and is fixed to the side seat body 12. When the sliding member 71 is subjected to an external force, the sliding member 71 can move along the slide rail 73.

[0074] The rotating transmission component 31 can also have a transmission belt 314, a driving wheel 315, and a driven wheel 316. The transmission belt 314 connects the driving wheel 315 and the driven wheel 316. The driving wheel 315 and the driving shaft 317 are coaxial and relatively limited or fixed. The driving wheel 315 and the driving shaft 317 can rotate synchronously, the driven wheel 316 and the positioning platform 2 rotate synchronously, and the transmission belt 314 rotates synchronously with the driving wheel 315 and the driven wheel 316.

[0075] A portion of the driving shaft 317 is located at the driving wheel 315, and a portion of the driving shaft 317 is located at the second gear 312. The driving shaft 317 and the driving wheel 315 are fixed or limited, and the driving shaft 317 and the second gear 312 are fixed or limited. In this way, when the second gear 312 rotates, the driving shaft 317 can also rotate at the same time, so that the driving wheel 315 can also rotate together.

[0076] As an embodiment, when the positioning platform 2 needs to rotate 90°, the driving shaft 317 has a first hole 3172 and a second hole 3173, and the first hole 3172 and the second hole 3173 are arranged at different circumferential positions of the driving shaft 317, and the limit pin 72 is adapted to the first hole 3172 and the second hole 3173; the sliding component 71 has at least a first position and a second position, in the first position, at least a part of the limit pin 72 is located in the first hole 3172 or the second hole 3173, and in the second position, the limit pin 72 is not located in the first hole 3172 and the second hole 3173.

[0077] In this way, the sliding component 71 can move under the action of external force. During the movement of the sliding component 71, at least part of the limit pin 72 is located in the first hole 3172 or the second hole 3173. In the second position, the limit pin 72 is not located in the first hole 3172 and the second hole 3173, thereby realizing the position locking and unlocking of the driving shaft 317, and further facilitating the locking of the rotational position of the positioning platform 2. In this way, this embodiment can be realized through automation.

[0078] The axis of the first hole 3172 and the axis of the second hole 3173 can be vertically arranged. A portion of the end of the stop pin 72 is smaller than the size of the first hole 3172 and the second hole 3173, and a portion of the stop pin 72 can be limited in the first hole 3172 or the second hole 3173.

[0079] As another embodiment, when the positioning platform 2 needs to rotate 180°, the driving shaft 317 has a limit hole 3171, and the sliding component 71 has at least a first position and a second position. In the first position, at least a portion of the limit pin 72 is located in the limit hole 3171, and in the second position, the limit pin 72 is not located in the limit hole 3171.

[0080] Of course, as other embodiments, when the positioning platform 2 needs to rotate 270°, the driving shaft 317 also needs the first hole 3172 and the second hole 3173. As other embodiments, for example, when the positioning needs to rotate an angle between 0-90° or an angle between 180-270°, the limit hole 3171 on the driving shaft 317 can also be adjusted accordingly. It should be understood that these are all within the scope of this application and will not be repeated here.

[0081] The self-locking mechanism 7 includes a seat 74, which is fixed to the support seat 1 and has a through hole 75; the sliding component 71 includes a connecting rod 711 and a moving block 712, the connecting rod 711 and the moving block 712 are fixed or integrally formed, a part of the connecting rod 711 is located in the through hole 75, and the connecting rod 711 has an external force matching portion 7111 for matching with an external force. The seat 74 can be used to support the connecting rod 711. The connecting rod 711 can move relative to the seat 74 under the action of an external force.

[0082] In this embodiment, the self-locking mechanism 7 further comprises an abutment seat 76 and an elastic member 77 , one end of the elastic member 77 is connected to the abutment seat 76 , and the other end of the elastic member 77 is connected to the limit pin 72 .

[0083] For example, when the connecting rod 711 is subjected to an external thrust, the connecting rod 711 moves, driving the sliding member 71 to move, so that the limiting pin 72 exerts a pressing force on the elastic member 77, so that the limiting pin 72 inserted into the limiting hole 3171 of the driving shaft 317 is separated from the driving shaft 317. At this time, the driving shaft 317 can rotate, driving the positioning platform 2 to rotate, and is used for flipping the positioning platform 2. The driving shaft 317 can be driven to rotate by the rotation of the output shaft 313. For example, when the flipping requires 90°, the limiting pin 72 firstly disengages from the first hole 3172.

[0084] When the positioning platform 2 is rotated into place, the external force of the connecting rod 711 is withdrawn, and the sliding component 71 can move under the action of the rebound force of the elastic component 77, so that the limit pin 72 can be inserted into the second hole 3173 of the driving shaft 317. In this way, the position of the driving shaft 317 is limited, so that the driving shaft 317 cannot rotate, so that the position locking of the positioning platform 2 can be achieved after it is flipped to a certain position, so that the processing of the positioning platform 2 after flipping will not affect the position flipping of the positioning platform 2.

[0085] As another embodiment, the external force may also be a pulling force, for example, the connecting rod 711 may be a metal part, which moves in a direction away from the driving shaft 317 under the action of an external force, such as a magnetic force or other power components, so that the limiting pin 72 originally located in the limiting hole 3171 of the driving shaft 317 can be separated from the driving shaft 317, and at this time, the positioning platform 2 can be easily turned over. After the rotation is in place, the external force is removed, and the connecting rod 711 can be inserted into the limiting hole 3171 of the driving shaft 317.

[0086] In this embodiment, the sliding component 71 has a connecting rod 711 and a moving block 712, the connecting rod 711 and the moving block 712 are fixed or integrally formed, a part of the connecting rod 711 is located in the through hole 75, and the connecting rod 711 has an external force matching portion 7111 for matching with an external force. The connecting rod 711 may include a first rod, an elastic member, and a second rod, one end of the elastic member is connected to the first rod, the other end of the elastic member is connected to the second rod, the second rod has an external force matching portion 7111 for matching with an external force, and the first rod and the moving block are fixed or limited. In this way, when there is external suction, the second rod drives the elastic member to pull the first rod to move, and when the external force is removed, the elastic member resets and pushes the first rod to move toward the driving shaft.

[0087] As another embodiment, the connecting rod 711 can also be moved in a direction away from the driving shaft 317 by other power components. Other power components can achieve the above functions and can have various structures, which will not be described in detail herein.

[0088] As another embodiment, the output shaft 313 can also be arranged along the length direction, and the rotating transmission component 31 includes the output shaft 313, and the first end 3131 of the output shaft 313 has a shaft matching portion 3132, and the shaft matching portion 3132 is used to match with an external force mechanism, such as a motor, a cylinder, etc. The second end 3133 of the output shaft 313 is fixed or limited to the rotating shaft 32, so that when the output shaft 313 is rotated by an external force, the output shaft 313 can directly drive the rotating shaft 32 to rotate, and the fixing method of the rotating shaft 32 and the positioning platform 2 can refer to the above, so that the external force can automatically flip the positioning platform 2.

[0089] As other embodiments, refer to Fig.13 The rotating transmission component 31 includes an output shaft 313, a second gear 312, and a rack seat 318. The output shaft 313 and the rack seat 318 can be an integral structure or a fixed arrangement. The second gear 312 is meshed with the rack seat 318, and the second gear 312 is connected to the rotating shaft 32 by transmission. The second gear 312 can drive the rotating shaft 32 to rotate. One end of the output shaft 313 has a shaft matching portion 3132 for matching with an external force, such as a cylinder. Under the action of an external force, the output shaft 313 moves, driving the rack seat 318 to move, so that the second gear 312 can rotate.

[0090] In order to further prevent the interference of parts, the rotating transmission component 31 also has a driving wheel 315, a transmission belt 314, and a driven wheel 316. The driving wheel 315 and the second gear 312 are coaxially arranged, and the second gear 312 can drive the driving wheel 315 to rotate. The transmission belt 314 connects the driving wheel 315 and the driven wheel 316, and the driven wheel 316 and the rotating shaft 32 are coaxially arranged. In this way, the positioning platform 2 can be driven to rotate through the transmission belt 314.

[0091] It should be understood that the structure of the rotating transmission component 31 is not limited to the above embodiment, and may also have structures such as a screw rod, multiple gears, etc. The rotating transmission component 31 utilizes the output shaft 313 to convert external force into the rotation of the rotating shaft 32.

[0092] Reference Figure 10-12 A processing machine 30 includes a machine base 40, a carrier tool 10 and a driving mechanism 20. The carrier tool 10 has a support base 1 and a positioning platform 2. The positioning platform 2 can rotate relative to the support base 1.

[0093] The object carrier 10 may further include a rotating mechanism 3 , wherein the rotating mechanism 3 may be described with reference to the above.

[0094] At least part of the rotating mechanism 3 can drive the positioning platform 2 to rotate; the rotating mechanism 3 includes a rotating transmission component 31 and a rotating shaft 32; the rotating transmission component 31 is in transmission connection with the rotating shaft 32, and the rotating transmission component 31 can drive the rotating shaft 32 to rotate.

[0095] The driving mechanism 20 is located on the machine base 40 . The driving mechanism 20 can drive the rotating shaft 32 to rotate, and the rotating shaft 32 can drive the positioning platform 2 to rotate.

[0096] The processing machine may have a conveyor chain 301, the carrier 10 is located on the conveyor chain 301, the drive mechanism 20 is located on the side of the conveyor chain 301, the extension direction of the rotation axis 32 is defined as the first direction, the extension direction of the drive axis of the first power component 22 is defined as the second direction, the second direction is perpendicular to the first direction, and the drive mechanism 20 is located on the side of the carrier 10. In this way, when the first direction is the conveying direction of the conveyor chain 301 below the carrier 10, by arranging the drive mechanism 20 connected to the output shaft 313 on one side of the width direction of the carrier 10, when necessary, it is matched with the output shaft 313 to provide rotational force, and when not needed, the drive mechanism 20 is on the side of the carrier 10, so that it is more conducive to the circulation of the carrier 10 on the conveyor chain 301.

[0097] The driving mechanism 20 includes a first driving member 21 and a first power component 22 . The action component of the first driving member 21 is fixed to the first power component 22 . The first driving member 21 can push the first power component 22 to move, and the first power component 22 can approach or move away from the rotating transmission component 31 .

[0099] Specifically, the first driving member 21 may be a first air cylinder, an electric cylinder, or the like.

[0100] When the position of the carrier 10 is determined, the first driving member 21 moves to push the first power component 22 toward the carrier 10 , so that the driving shaft of the first power component 22 can be connected to the output shaft 313 , and the first power component 22 can drive the output shaft 313 to rotate.

[0101] When the positioning platform 2 of the carrier 10 does not need to rotate, the first driving member 21 drives the first power component 22 to move in a direction away from the carrier 10, so that the first power component 22 and the output shaft 313 are disconnected, so that the first power component 22 can leave the carrier 10, which is convenient for the circulation of the carrier 10 on the conveyor chain 301. In this way, the flipping action of the positioning platform 2 of the carrier 10 does not affect the operation of the conveyor chain 301, nor does it affect the subsequent circulation of other positions, so that the flipping and circulation of the positioning platform 2 on the carrier 10 can be achieved mechanically, and the movement of the workpiece on the carrier 10 can be automatically realized on the conveyor chain 301, and can be used in an automated production line.

[0102] As a specific embodiment, the first power component 22 can be a motor, the drive shaft of the motor has a structure that is compatible with the shaft matching portion 3132 of the output shaft 313, at least part of the drive shaft of the motor is located in the shaft matching portion 3132 of the output shaft 313, or at least part of the shaft matching portion 3132 of the output shaft 313 is located in the drive shaft.

[0103] More specifically, the driving mechanism 20 includes a fixing seat 23, and the fixing seat 23 is fixedly arranged with the machine base 40 of the machine platform. The driving base 11 of the first driving member 21 is fixed with the fixing seat 23.

[0104] The driving mechanism 20 has a sliding module 24 and a bracket 25. The sliding module 24 has a slide rail 241 and a slider 242. The slide rail 241 is arranged on the fixing seat 23. The bracket 25 and the slider 242 are fixed. The slider 242 and the action part of the first driving member 21 are fixed. Thus, when the first driving member 21 is actuated, the slider 242 and the bracket 25 can be driven to move along the slide rail 241. The first power component 22 and the bracket 25 are fixed. Thus, the first driving member 21 can drive the first power component 22 to approach or move away from the object carrying tool 10.

[0109] In this embodiment, the push rod and the bracket 25 are fixed. When the first driving member 21 drives the bracket 25 to move toward the object-carrying fixture 10, the push rod also moves toward the object-carrying fixture 10. Along the width direction of the object-carrying fixture 10, the push rod and the connecting rod 711 are in corresponding positions. When the push rod moves toward the object-carrying fixture 10, it can push the connecting rod 711, so that the connecting rod 711 moves relative to the bearing seat 74, and the connecting rod 711 then drives the sliding component 71 to move, so that the driving shaft 317 is not limited by the limit pin 72. When the first driving member 21 is reset, the action component of the first driving member 21 drives the bracket 25 to move in the direction away from the object-carrying fixture 10, the push rod leaves the connecting rod 711, and the connecting rod 711 is reset under the action of the elastic member 77.

[0110] In this way, the drive mechanism 20 has both an action component for rotating the positioning table 2 and a self-locking mechanism 7 for locking the rotation position, so that the carrier tooling 10 can automatically realize the functions of unlocking, flipping and self-locking on this machine through mechanical means, which is powerful.

[0111] In addition, the arrangement of the driving mechanism 20 will not affect the circulation of the carrier tooling 10 on the conveyor chain 301, and can meet the needs of an automated production line with multiple processing stations, and has wide applicability.
