When a component is considered to be "set on" another component, it may be directly set on the other component or there may be a central component at the same time.

[0064] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0065] Some embodiments of the present application are described in detail below in conjunction with the accompanying drawings.

[0066] Please also read Figure 1 , Figure 2 and Figure 3 The transmission device 100 provided in an embodiment of the present application is used to transmit a product (not shown), the product is provided with a positioning portion, and the transmission device 100 includes a transmission mechanism 10 and a locking mechanism 20.

[0067] The transmission mechanism 10 includes two transmission frames 11 and a carrier 12, wherein the two transmission frames 11 are arranged at intervals along a first direction X. The carrier 12 is slidably arranged on the two transmission frames 11 along a second direction Y, wherein the first direction X is perpendicular to the second direction Y. The carrier 12 is provided with a bearing surface 121, and the bearing surface 121 is used to bear the product. The carrier 12 is also provided with a receiving cavity 122 and a through hole 123, wherein the through hole 123 connects the bearing surface 121 and the receiving cavity 122, and the through hole 123 is configured to allow the positioning portion to pass through so as to extend into the receiving cavity 122.

[0068] The locking mechanism 20 includes a pusher 21, a rotating member 22 and a locking member 23. The pusher 21 is slidably disposed in the receiving cavity 122 along the first direction X. The pusher 21 is provided with an inclined surface 211 on one side wall of the second direction Y, and the inclined surface 211 is inclined relative to the first direction X. The rotating member 22 slides against the inclined surface 211. The rotating member 22 has an axis O and is rotatably disposed around the axis O. The axis O is inclined to the plane where the first direction X and the second direction Y are located. The locking member 23 is connected to one end of the rotating member 22. When the pusher 21 moves along the first direction X, the pusher 21 drives the rotating member 22 to rotate around the axis O in the receiving cavity 122 and drives the rotating member 22 to move in the second direction Y at the same time. The locking member 23 is configured to move toward or away from the through hole 123 under the drive of the rotating member 22 to resist or release the positioning portion.

[0069] In the above-mentioned transmission device 100, after the product is placed on the bearing surface 121 of the carrier 12, the pushing member 21 is moved along the first direction X in the receiving cavity 122. At this time, the rotating member 22 slides along the inclined surface 211 on the pushing member 21, so that the rotating member 22 drives the locking member 23 to move along the second direction Y toward or away from the positioning portion extending into the receiving cavity 122, so that the locking member 23 can abut against or release the positioning portion. When the locking member 23 abuts against the positioning portion, the stability of the product when it is located on the carrier 12 can be improved, so as to reduce the risk of the product detaching from the carrier 12 when the carrier 12 drives the product to move between the transmission racks 11.

[0070] In other embodiments, a concave portion (not shown) is formed by the self-propelling member 21 being concave toward or away from the side of the bearing surface 121, and the concave portion includes a side wall, and the side wall includes an inclined surface 211 and a smooth surface 212 that are connected and arranged. In this case, one end of the rotating member 22 can be embedded in the concave portion to abut against the inclined surface 211 or the smooth surface 212. It can be understood that when the pushing member 21 moves along the first direction X, when the rotating member 22 moves from the smooth surface 212 to the inclined surface 211, the locking member 23 moves along the second direction Y to abut against the positioning portion, thereby achieving the purpose of locking the product. On the contrary, when the rotating member 22 moves from the inclined surface 211 to the smooth surface 212, the locking member 23 moves along the second direction Y to move away from the positioning portion, thereby achieving the purpose of loosening the product.

[0071] In other embodiments, the push member 21 is provided with a sliding hole 213 extending therethrough, the inclined surface 211 and the smooth surface 212 are provided on the hole wall of the sliding hole 213, and the rotating member 22 is partially provided in the sliding hole 213 to form the inclined surface 211 and the smooth surface 212. Through the above arrangement, the rotating member 22 is provided in the sliding hole 213, which can limit the movement stroke of the push member 21 in the first direction X, and reduce the risk of the rotating member 22 being separated from the push member 21.

[0072] Please also read Figure 1 and Figure 2In some embodiments, the carrier 12 includes a first carrier portion 124 and a second carrier portion 125, and the first carrier portion 124 is slidably disposed between the two transmission racks 11 along the second direction Y. The second carrier portion 125 is connected to the side of the first carrier portion 124 that is away from the transmission rack 11 in the third direction Z, and the receiving cavity 122 is formed between the first carrier portion 124 and the second carrier portion 125. The projection of the second carrier portion 125 in the third direction Z is located within the projection range of the first carrier portion 124 in the third direction Z, the first direction X, the second direction Y and the third direction Z are perpendicular to each other, and the third direction Z is parallel to the axis O. Through the above arrangement, the first carrier portion 124 moves between the two transmission racks 11, and the second carrier portion 125 is responsible for carrying the product.

[0073] Please continue reading Figure 1 and Figure 2 In some embodiments, the transmission mechanism 10 further includes a lifting member 13, which is disposed between the two transmission racks 11. The lifting member 13 is configured to lift the bearing member 12 along the third direction Z so that the first bearing portion 124 is separated from the two transmission racks 11. Each transmission rack 11 is provided with a limiting portion 111, which is configured to abut against the side of the first bearing portion 124 away from the lifting member 13. Through the above arrangement, after the bearing member 12 moves to the limiting portion 111, the lifting member 13 lifts the bearing member 12, so that the limiting portion 111 abuts against the first bearing portion 124 while reducing the risk of the limiting portion 111 contacting the product on the second bearing portion 125. The lifting member 13 cooperates with the limiting portion 111 to fix the position of the bearing member 12 in the third direction Z, thereby improving the stability when the product is placed on the bearing member 12.

[0074] Please continue reading Figure 1 and Figure 2 In some embodiments, a first opening 126 communicating with the receiving cavity 122 is provided on one side of the carrier 12 close to one of the transmission racks 11, and the pushing member 21 includes a first pushing portion 214 and a second pushing portion 215, wherein the first pushing portion 214 is disposed in the receiving cavity 122 and connected to the rotating member 22. One end of the second pushing portion 215 is connected to an end of the first pushing portion 214 away from the rotating member 22, and the other end is configured to be retractably disposed in the first opening 126 under the action of an external force. Through the above arrangement, the external part can drive the second pushing portion 215 and the first pushing portion 214 connected to the second pushing portion 215 to move, so that the first pushing portion 214 can drive the rotating member 22 to rotate.

[0075] In this embodiment, the first pushing portion 214 and the second pushing portion 215 are an integrally formed structure, which improves the structural stability of the pushing member 21 .

[0076] Please continue reading Figure 1 and Figure 2In some embodiments, the locking mechanism 20 further includes a driving member 24 connected to the transmission frame 11. The transmission end of the driving member 24 is configured to move to the first opening 126 to push the second pushing portion 215 and the first pushing portion 214 connected to the second pushing portion 215 to move in the receiving cavity 122.

[0077] Please also read Figure 2 and Figure 3 In this embodiment, the sliding hole 213 is provided on the first pushing portion 214. The first pushing portion 214 is provided with a plurality of sliding holes 213, and accordingly, the locking mechanism 20 also includes a plurality of rotating members 22 and locking members 23, and the sliding holes 213, the rotating members 22 and the locking members 23 correspond to each other one by one, so that when the pushing member 21 moves along the first direction X, a plurality of products on the carrier 12 can be locked or unlocked at the same time.

[0078] Please also read Figure 3 and Figure 4 In some embodiments, the locking member 23 includes a fixing portion 231, a connecting portion 232, a locking portion 233 and a first elastic portion 234. The fixing portion 231 is connected to the cavity wall of the accommodating cavity 122 and is spaced apart from the rotating member 22 along the second direction Y. The fixing portion 231 is provided with a limiting groove 2311. One end of the connecting portion 232 is connected to the rotating member 22, and the other end passes through the fixing portion 231 and is slidably disposed in the limiting groove 2311 along the second direction Y. The locking portion 233 is disposed in the limiting groove 2311 and is spaced apart from the connecting portion 232. The first elastic portion 234 elastically abuts between the connecting portion 232 and the locking portion 233. The first elastic portion 234 is configured to abut the locking portion 233 toward the direction of the positioning portion of the product. Through the above arrangement, when the rotating member 22 slides from the smooth surface 212 to the inclined surface 211 and rotates, the connecting portion 232 can slide in the limiting groove 2311 of the fixing portion 231 along the second direction Y, and the connecting portion 232 can compress the first elastic portion 234, so that the first elastic portion 234 moves the locking portion 233 toward the positioning portion of the product to resist the positioning portion, thereby achieving the purpose of locking the product. On the contrary, when the rotating member 22 slides from the inclined surface 211 to the smooth surface 212, the connecting portion 232 drives the first elastic portion 234 and the locking portion 233 connected to the first elastic portion 234 to move in a direction away from the product, thereby achieving the purpose of unlocking the product, wherein the first elastic portion 234 promotes the locking portion 233 to reset.

The bearing 222 is configured to be slidably connected to the smooth surface 212 or the inclined surface 211. Through the above configuration, when the bearing 222 slides from the smooth surface 212 to the inclined surface 211 or from the inclined surface 211 to the smooth surface 212, the bearing 222 drives the rotating shaft 221 to rotate around the axis O, so that the rotating shaft 221 drives the connecting portion 232 to move along the second direction Y.

[0080] Please refer again Figure 1 and Figure 2 In some embodiments, the locking mechanism 20 further includes two groups of first positioning members 25 and one group of second positioning members 26, and the two groups of first positioning members 25 are connected to the bearing surface 121 at intervals along the first direction X.
