[0040] Combine the following Figure 1-Figure 13 , describing the unlocking buckle mechanism provided in an embodiment of the present application.

[0041] The embodiment of the present application provides an unlocking buckle mechanism, which can be applied to a scenario where a product needs to be limited, to achieve automatic unlocking of the buckle and automatic locking of the buckle; Figure 1 A schematic diagram of an unlocking buckle mechanism provided by an exemplary embodiment of the present application is shown. Figure 1 As shown, the unlocking buckle mechanism includes a tray 100 and an unlocking buckle device 200;

[0042] The tray 100 is provided with a receiving slot 110 for receiving products, and a plurality of lock buckles 120 are arranged around the receiving slot 110;

[0043] Figure 2 FIG. 1 shows a schematic diagram of the structure of a lock provided by an exemplary embodiment of the present application. Figure 2 As shown, the lock 120 includes a lock shaft 121, a lock block 122 and a protrusion 123. The lock shaft 121 passes through the tray 100. The lock block 122 is arranged on the structure of the lock shaft 121 above the tray 100, and the protrusion 123 is arranged on the structure of the lock shaft 121 below the tray 100. The protrusion 123 is used to drive the lock shaft 121 and the lock block 122 to rotate.

[0044] In one possible implementation, Figure 2 As shown, the orientation of the protrusion 123 is consistent with the orientation of the locking block 122, or the angle between the orientation of the protrusion 123 and the orientation of the locking block 122 is within the target range, or the orientation of the protrusion 123 can also be opposite to the orientation of the locking block 122. The present application does not limit the relative direction relationship between the protrusion 123 and the locking block 122.

[0045] In one possible implementation, the locking shaft 121 may be a non-elastic structure, that is, a rigid structure; or, in another possible implementation, the locking shaft 121 may be an elastic structure, such as Figure 2 As shown, by setting the locking shaft 121 as an elastic structure, the locking block 122 can be lifted up under the action of the spring force or the locking block 122 can be pressed against the tray 100 under the action of the spring force.

[0046] Figure 3 A partial schematic diagram of an unlocking buckle device provided by an exemplary embodiment of the present application is shown. Figure 3 As shown, the unlocking buckle device 200 is arranged below the tray 100, and includes a base plate 210 and an unlocking buckle assembly 220 corresponding to each lock buckle, and the unlocking buckle assembly 220 includes a lever 221 and a rotating shaft 222, the lever 221 is arranged on a plane at one end of the rotating shaft 222, and the other end of the rotating shaft 222 is connected to the base plate 210 and can rotate relative to the base plate 210;

[0047] When the lock is locked, the rotating shaft 222 of each unlocking buckle assembly 220 drives the lever 221 to rotate the corresponding protrusion 123 until the protrusion 123 drives the lock buckle shaft 121 to rotate the lock block 122 to the locking position corresponding to the receiving groove 110; when the lock is unlocked, the rotating shaft 222 of each unlocking buckle assembly 220 drives the lever 221 to rotate the corresponding protrusion 123 until the protrusion 123 drives the lock buckle shaft 121 to rotate the lock block 122 to the unlocking position corresponding to the receiving groove 110.

[0048] In a possible implementation, the pallet 100 may be provided with one or more receiving slots 110, each of which may be used to receive a corresponding product. The present application does not limit the number of receiving slots provided on the pallet; the size and shape of the receiving slots may be set according to the product specifications to ensure stable placement of the product. The pallet may be a wave pallet, a water-washing pallet, a coating pallet, etc. The present application does not limit the type of pallet.

[0049] A plurality of locks 120 are arranged around the receiving groove 110. The structure of these locks 120 above the tray 100 includes a lock shaft 121 and a lock block 122. The lock block 122 is connected to the lock shaft 121, so that the lock block 122 can rotate with the rotation of the lock shaft 121. The structure below the tray 100 includes a lock shaft 121 and a protrusion 123. The protrusion 123 is fixedly connected to the lock shaft 121, so that under the action of the unlocking buckle device 200 on the protrusion 123, the lock shaft 121 and the lock block 122 are driven to rotate, thereby realizing the actions of locking and unlocking the lock; wherein, locking the lock refers to rotating the lock block to a specific angle range so that the edge of the lock block exceeds the edge of the receiving groove 110, causing a vertical obstruction to the product in the receiving groove 110 to prevent the product from sliding or popping out; unlocking the lock refers to rotating the lock block to another angle range so that the lock block no longer obstructs the product in the receiving groove 110, which is convenient for manual or automatic taking and placing.

[0050] The unlocking buckle device 200 includes a base plate 210 for providing an assembly basis for the unlocking buckle assembly 220; the design of the unlocking buckle assembly 220 enables the rotating shaft 222 to drive the lever 221 to rotate, and the length of the lever 221 enables the lever 221 to contact the protrusion 123 of the lock buckle 120 when the unlocking buckle device 200 reaches the working position, so as to drive the lever 221 to control the rotation of the protrusion 123 through the rotation of the rotating shaft 222; wherein, when the lock buckle is locked, the rotation direction of the rotating shaft causes the lever to push the protrusion, thereby driving the lock block to the locked position to fix the product, wherein the locked position may refer to the position where the lock block 122 intersects with the edge of the receiving groove 110; when the lock buckle is unlocked, the rotation direction of the rotating shaft causes the lever to push the protrusion, thereby driving the lock block to the unlocked position to release the product, wherein the unlocked position refers to the position where the lock block 122 does not intersect with the edge of the receiving groove 110.

[0051] In one possible implementation, the rotation direction of the rotating shaft is consistent when the lock buckle is locked and when the lock buckle is unlocked; or, in another possible implementation, the rotation direction of the rotating shaft is opposite when the lock buckle is locked and when the lock buckle is unlocked.

[0052] In summary, the unlocking buckle mechanism provided in the embodiment of the present application includes: a tray, and an unlocking buckle device; wherein, a receiving groove for accommodating products is provided on the tray, and a plurality of locks are arranged around the receiving groove on the tray, the lock includes a lock shaft, a lock block and a protrusion, the lock shaft passes through the tray, the lock block is provided on the structure where the lock shaft is located above the tray, and the protrusion is provided on the structure where the lock shaft is located below the tray, and the protrusion is used to drive the lock shaft and the lock block to rotate; the unlocking buckle device is arranged below the tray, including a base plate and an unlocking buckle assembly corresponding to each lock, the unlocking buckle assembly including a lever arranged on a plane at one end of a rotating shaft, the rotating shaft of each unlocking buckle assembly drives the lever to rotate the protrusion in the corresponding lock to drive the lock shaft to rotate the lock block, thereby locking the lock or unlocking the lock; the setting of the unlocking buckle mechanism can be flexibly adapted to the application scenarios of multiple locks, and has good versatility while realizing the automation of the unlocking buckle.

[0053] Figure 4 Another partial schematic diagram of an unlocking buckle mechanism provided by an exemplary embodiment of the present application is shown. Figure 4 As shown, the unlocking buckle mechanism includes a tray 100 and an unlocking buckle device 200;

[0054] The tray 100 is provided with a receiving groove 110 for receiving products, and a plurality of locks 120 are arranged around the receiving groove 110. The locks 120 include a lock shaft 121, a lock block 122 and a protrusion 123. The lock shaft 121 passes through the tray 100. The lock block 122 is provided on the structure of the lock shaft 121 located above the tray 100, and the protrusion 123 is provided on the structure of the lock shaft 121 located below the tray 100. The protrusion 123 is used to drive the lock shaft 121 and the lock block 122 to rotate.

[0055] The unlocking buckle device 200 is arranged below the tray 100, and includes a base plate 210 and an unlocking buckle assembly 220 corresponding to each lock buckle. The unlocking buckle assembly 220 includes a lever 221 and a rotating shaft 222. One end of the rotating shaft 222 is connected to the lever 221, and the other end of the rotating shaft 222 is connected to the base plate 210 and rotates relative to the base plate 210.

[0056] In one possible implementation, the rotating shaft 222 of each unlocking buckle assembly 220 is coaxial with the locking shaft 121 of the corresponding locking buckle 120 in the vertical direction, that is, the center line of the rotating shaft 222 is consistent with the center line of the locking shaft 121 in the vertical plane, so as to ensure that the unlocking buckle assembly 220 can accurately interact with the protrusion 123 on the locking shaft 121. The alignment setting can also ensure that the force transmission direction is optimized when rotating the lock block, thereby reducing unnecessary friction and wear and ensuring the smooth action of the unlocking buckle.

[0057] In one possible implementation, one end of the rotating shaft of each unlocking buckle assembly 220 connected to the base plate 210 is respectively connected to a corresponding independent driving device, so that when the unlocking buckle operation is performed, the rotation state of each unlocking buckle assembly can be controlled by controlling the start and stop and the working power of each independent driving device, and the rotation state includes whether to rotate and the rotation rate.

[0058] Or, in another possible implementation, Figure 5 A schematic diagram of an unlocking buckle device provided by an exemplary embodiment of the present application is shown. Figure 5 As shown, one end of the rotating shaft of each unlocking buckle assembly is connected to the base plate 210 through a synchronous belt 230; the synchronous belt 230 is connected to a first driving device, and the first driving device is used to control the rotation state of the rotating shaft; Figure 5As shown, one end of the rotating shaft of each unlocking buckle assembly connected to the substrate 210 is located below the substrate 210; in this case, by controlling the start and stop and working efficiency of the first drive device, the rotation state of all unlocking buckle assemblies connected to the synchronous belt can be controlled, and the consistency of the rotation state of each unlocking buckle assembly can be ensured; the first drive device can be implemented as various motors (such as servo motors, stepper motors) and various drivers, etc., and the present application does not limit the type of the first drive device.

[0059] In one possible implementation, the bottom of the locking block of the lock 120 is chamfered to ensure smoothness during the rotation of the lock. At the same time, the chamfer design can improve the safety of the lock application and prevent the lock from causing damage to the product or harm to the human body.

[0060] In a possible implementation, the unlocking buckle device 200 is connected to a second driving device 300, and the second driving device 300 is used to control the lifting and lowering of the unlocking buckle device 200; the second driving device 300 is arranged below the unlocking buckle device 200; Figure 6 FIG. 1 shows a schematic diagram of the structure of an unlocking buckle mechanism provided by an exemplary embodiment of the present application. Figure 6 As shown, one end of the second driving device 300 can be fixed on the bracket of the unlocking buckle mechanism, and the other end is connected to the unlocking buckle device 200. Under the action of the second driving device 300, the unlocking buckle device 200 can be controlled to rise or fall to adjust the relative position of the unlocking buckle device 200 relative to the tray 100 to ensure that the lever 221 can contact the protrusion 123 in the vertical direction.

[0061] Based on the above-mentioned unlocking buckle mechanism, during the application process, the unlocking buckle device 200 is suspended below the tray 100 under the action of the second driving device, and each unlocking buckle component 220 corresponds to the position of each lock buckle 120, and the lever 221 can make the protrusion 123 of the lock buckle 120 drive the lock buckle shaft 121 to rotate the lock block 122 under the drive of the rotating shaft 222; wherein, when the lock buckle is locked, the rotating shaft 222 of each unlocking buckle component 220 drives the lever 221 to rotate the corresponding protrusion 123, until the protrusion 123 drives the lock buckle shaft 121 to rotate the lock block 122 to the locking position corresponding to the accommodating groove 110; when the lock buckle is unlocked, the rotating shaft 222 of each unlocking buckle component 220 drives the lever 221 to rotate the corresponding protrusion 123, until the protrusion 123 drives the lock buckle shaft 121 to rotate the lock block 122 to the unlocking position corresponding to the accommodating groove 110.

[0062] In a possible implementation, the lock block 122 may be equipped with a position sensor. Figure 4The unlocking buckle mechanism shown, when the lock buckle is locked, when the position sensor detects that the lock block 122 intersects with the edge of the receiving groove 110 and the intersection angle reaches the first target angle, the first driving device is controlled to stop so that the lock block rotates to the locking position corresponding to the receiving groove 110; optionally, the first target angle can be 90°, or the first target angle can also be set to other values ​​based on actual needs, such as 80°, 85°, etc.; when the lock buckle is unlocked, when the position sensor detects that the lock block 122 does not intersect with the edge of the receiving groove 110, the first driving device is controlled to stop so that the lock block rotates to the unlocking position corresponding to the receiving groove 110, or, further, when the position sensor detects that the lock block 122 does not intersect with the edge of the receiving groove 110, the rotation angle of the lock block 122 is further determined, and when the rotation angle reaches the second target angle, it is determined that the unlocking position is reached, for example, after the position sensor detects that the lock block 122 does not intersect with the edge of the receiving groove 110, it is further detected that the lock block 122 rotates over 90°, and the first driving device is controlled to stop.

[0063] In this case, when the lock buckle is locked and unlocked, the rotation direction of the rotating shaft 222 can be the same or different.

[0064] In summary, the unlocking buckle mechanism provided in the embodiment of the present application includes: a tray, and an unlocking buckle device; wherein, a receiving groove for accommodating products is provided on the tray, and a plurality of locks are arranged around the receiving groove on the tray, the lock includes a lock shaft, a lock block and a protrusion, the lock shaft passes through the tray, the lock block is provided on the structure where the lock shaft is located above the tray, and the protrusion is provided on the structure where the lock shaft is located below the tray, and the protrusion is used to drive the lock shaft and the lock block to rotate; the unlocking buckle device is arranged below the tray, including a base plate and an unlocking buckle assembly corresponding to each lock, the unlocking buckle assembly including a lever arranged on a plane at one end of a rotating shaft, the rotating shaft of each unlocking buckle assembly drives the lever to rotate the protrusion in the corresponding lock to drive the lock shaft to rotate the lock block, thereby locking the lock or unlocking the lock; the setting of the unlocking buckle mechanism can be flexibly adapted to the application scenarios of multiple locks, and has good versatility while realizing the automation of the unlocking buckle.

[0065] In another possible implementation, in order to achieve a better locking effect of the lock, Figures 1 to 6 On the basis of any of the unlocking buckle mechanisms shown, the unlocking buckle mechanism includes a blocking block corresponding to each lock buckle, so as to block the protrusion during the rotation of the lock buckle driven by the protrusion, so that the lock buckle stays in the locked position; Figure 7 Another partial schematic diagram of an unlocking buckle mechanism provided by an exemplary embodiment of the present application is shown. Figure 7 As shown, the unlocking buckle mechanism includes a tray 100 and an unlocking buckle device 200;

[0066] The tray 100 is provided with a receiving groove 110 for receiving products, and a plurality of locks 120 are arranged around the receiving groove 110. The locks 120 include a lock shaft 121, a lock block 122 and a protrusion 123. The lock shaft 121 passes through the tray 100. The lock block 122 is provided on the structure of the lock shaft 121 located above the tray 100, and the protrusion 123 is provided on the structure of the lock shaft 121 located below the tray 100. The protrusion 123 is used to drive the lock shaft 121 and the lock block 122 to rotate.

[0067] The unlocking buckle device 200 is arranged below the tray 100, and includes a base plate 210 and an unlocking buckle assembly 220 corresponding to each lock buckle. The unlocking buckle assembly 220 includes a lever 221 and a rotating shaft 222. The lever 221 is arranged on a plane at one end of the rotating shaft 222. The other end of the rotating shaft 222 is connected to the base plate 210 and can rotate relative to the base plate 210. The blocking block 240 is arranged on the base plate 210.

[0068] In addition, if Figure 7 As shown, the unlocking buckle mechanism includes a blocking block 240 corresponding to each lock buckle 120, and the blocking block 240 is configured on the upper plane of the base plate 210;

[0069] The blocking block 240 is located on the rotation path of the corresponding protrusion 123. Furthermore, the position of the blocking block 240 corresponds to the locking position of the locking block 122 relative to the receiving groove 110, so that the locking block 122 corresponding to the protrusion 123 rotates to the locking position corresponding to the receiving groove 110. The shape of the protrusion 123 can be consistent with that of the locking block 122, or it can be a different shape from that of the locking block 122. For example, the protrusion 123 can be a cuboid, a cube, or any other polyhedron, and the present application does not limit this.

[0070] In one possible implementation, there is a certain distance between the blocking block 240 and the rotating shaft 222 to ensure that the rotating shaft 222 can normally drive the lever 221 to rotate, and the distance between the edge of the protruding portion of the protrusion 123 and the rotating shaft 222 is greater than the distance between the blocking block 240 and the rotating shaft 222 to ensure that the blocking block 240 is on the rotation path of the protrusion 123.

[0071] The blocking block 240 is disposed on the first plane side of the protrusion 123. In this case, when the lock buckle is locked, the rotation direction of the shaft 222 is directed from the second plane to the first plane. After the lock buckle is locked, if the lock buckle on the same tray is unlocked, the rotation direction of the shaft 222 is directed from the first plane to the second plane. That is, under the action of the blocking block 240, the rotation direction of the shaft when the lock buckle is locked is opposite to the rotation direction of the shaft when the lock buckle is unlocked. Figure 7Taking the entry position of the unlocking buckle assembly as an example, the lock buckle is currently in the unlocking state. During the process of locking the lock buckle, the rotating shaft 222 drives the lever 221 to rotate clockwise, and drives the protrusion 123 to rotate clockwise. When the protrusion 123 rotates to the position of the blocking block 240, it will be blocked by the blocking block 240; Figure 8 A schematic diagram showing a locking state of a lock provided by an exemplary embodiment of the present application is shown in FIG. Figure 8 As shown, after the above-mentioned locking process of the lock buckle, the protrusion 123 is blocked by the blocking block 240, and the lock block 122 of the lock buckle 120 rotates to the locked position; optionally, a collision sensor can be configured on the blocking block 240 or the protrusion 123. After the collision sensor detects that the blocking block 240 collides with the protrusion 123, it can instruct the first driving device to stop, so that the lock block 122 stays in the locked position, or the collision sensor can issue a prompt message after detecting a collision to instruct relevant personnel to shut down the first driving device; in the process of unlocking the lock buckle, the rotating shaft 222 drives the lever 221 to rotate counterclockwise, and drives the lock block 122 to rotate counterclockwise through the lock buckle shaft 121, so that the lock block 122 is away from the blocking block 240, Fig. 9 A schematic diagram showing a lock unlocking state provided by an exemplary embodiment of the present application is shown in FIG. Fig. 9 As shown, in Figure 8 In the locked lock state shown, driven by the lever 221, the lock block 122 is rotated in the direction away from the blocking block 240 until it reaches the unlocked position, thereby completing the unlocking of the lock; optionally, a position sensor may be configured on the lock block 122, and when the position sensor detects that the lock block 122 does not intersect the edge of the accommodating groove 110, the rotation angle of the lock block 122 is further judged, and when the rotation angle reaches the second target angle, it is determined that the unlocked position is reached, or when the position sensor detects that the lock block 122 rotates through a third target angle from a stopped state; wherein, the second target angle and the third target angle can take values ​​within their respective corresponding angle ranges, and the setting of the angle range can at least ensure that after the lock block 122 rotates to an angle within the angle range, the lock block 122 does not intersect the edge of the accommodating groove 110.

[0072] In one possible scenario, the unlocking buckle device needs to lock or unlock the buckles of different pallets 100. In this scenario, the unlocking buckle device needs to repeat the process of entering and exiting. Since the buckle states corresponding to different pallets 100 may be different, during the process of the unlocking buckle device 200 rising under the drive of the second driving device 300, the lever 221 and the protrusion 123 may interfere with each other. During the transportation of the pallet 100, under the action of the friction force on the surface of the pallet 100, the buckle swings usually within a swing angle (for example, 20°). Therefore, in order to prevent the lever 221 from interfering with the protrusion 123, the entry position of the lever 221 on the unlocking buckle device 200 can be located outside the swing angle range of the protrusion 123 relative to the unlocking position or the locking position. Schematically, as shown in FIG. Figure 7 As shown, in the scenario of locking the lock buckle, the lock buckle 120 is in the unlocked position, or in a position after swinging based on the unlocked position, the lever 221 on the unlocking buckle device 200 can enter the locked position to avoid interference between the lever 221 and the protrusion 123; correspondingly, in the scenario of unlocking the lock buckle, the lock buckle 120 is in the locked position, and the lever 221 on the unlocking buckle device 200 can enter the unlocked position to avoid interference between the lever 221 and the protrusion 123.

[0073] Furthermore, in order to avoid interference between the protrusion 123 and the blocking block 240 in the scenario of unlocking the lock buckle, in a possible implementation, the blocking block 240 is set in the locked position and is set to a detachable structure. In the scenario of unlocking the lock buckle, the blocking block 240 is removed. This can avoid interference between the blocking block 240 and the protrusion 123 when the unlocking buckle device 200 enters in the scenario of unlocking the lock buckle, and can also avoid the blocking block 240 from restricting the rotation direction of the shaft 222 when unlocking the lock buckle, that is, the rotation direction of the shaft 222 is not restricted; in the scenario of locking the lock buckle, the blocking block 240 is installed to the locked position.

[0074] Alternatively, in another possible implementation, the blocking block 240 can be configured as a movable structure, and in the scenario of unlocking the lock buckle, the blocking block 240 is moved to a position outside the swing angle range of the protrusion 123 relative to the locking position; further, the blocking block 240 can be moved to a position corresponding to the unlocking position of the locking block 122 relative to the accommodating groove 110, which can avoid the interference between the blocking block 240 and the protrusion 123 when the unlocking buckle device 200 enters in the scenario of unlocking the lock buckle, and can also play a role in limiting the locking block 122 in the scenario of unlocking the lock buckle. In addition, the blocking block 240 can also avoid restricting the rotation direction of the rotating shaft 222 when unlocking the lock buckle, that is, the rotation direction of the rotating shaft 222 is not restricted.

[0075] In order to reduce the risk of scratching the product contained in the receiving groove during the unlocking process, the locking block 122 of the lock 120 can be lifted to a certain height during the unlocking process of the unlocking mechanism. After the unlocking operation is completed, the locking block 122 is dropped back to a state of contact with the tray 100 to achieve the effect of limiting the position of the product. In this case, a rotating support block 223 is also provided on the plane of the rotating shaft 222. Fig.10 A partial schematic diagram of an unlocking buckle device provided by an exemplary embodiment of the present application is shown. Fig.10 As shown, a rotating support block 223 is arranged on the plane of the rotating shaft 222, and the rotating support block 223 floats around the rotating shaft 222 and rotates adaptively; wherein, the floating and adaptive rotation setting allows the rotating support block 223 to rotate freely within a certain range and can automatically adjust its rotation angle according to external conditions.

[0076] Before the unlocking buckle device performs the unlocking buckle operation, the unlocking buckle device is lifted until each rotating support block contacts the corresponding protrusion of the lock buckle, and the lock buckle is lifted to a target height.

[0077] That is to say, during the lifting process of the unlocking buckle device 200, after the rotating support block 223 contacts the protrusion 123 of the lock buckle 120, the unlocking buckle device 200 continues to lift, and the lock block is lifted to the target height in the direction away from the tray 100 through the lock buckle shaft. In this state, the rotating support block 223 is in close contact with the protrusion 123. In the process of the rotating shaft 222 driving the lever 221 to rotate the protrusion 123, due to the circumferential floating and adaptive rotation setting of the rotating support block 223, before the lever 221 contacts the protrusion 123, the sliding friction between the bottom of the protrusion 123 and the corresponding supporting surface can be converted into the rolling friction of the rotating support block 223 itself, which can reduce the wear on the bottom of the protrusion 123 and the driving force of the rotating shaft 222, and the operation is more reliable and stable.

[0078] The locking shaft is a spring shaft. In this case, after the lock 120 is lifted to the target height, the locking shaft 121 is in a compressed state; after the unlocking buckle device 200 is lowered, under the action of the locking shaft 121, the locking block 122 is driven to fall back onto the tray 100 or onto the product accommodated in the receiving groove 110; wherein, when the lock is locked, all or part of the locking block 122 falls onto the product accommodated in the receiving groove 110, and when the lock is unlocked, the locking block 122 falls onto the tray 100.

[0079] Since the lock buckle 120 is disposed on the tray 100, the tray 100 may be lifted upwards when the unlocking buckle device 200 lifts the lock buckle 120. In this case, in order to achieve the effect of maintaining a certain distance between the lower surface of the lock buckle and the upper surface of the tray, the mechanism includes a plurality of pressing plates 400. Fig.11FIG. 1 shows a partial schematic diagram of another unlocking buckle mechanism provided by an exemplary embodiment of the present application, such as Fig.11 As shown, the pressure plate 400 is arranged above the pallet 100, and the protruding portion of the pressure plate 400 partially overlaps with the pallet 100 in the vertical direction; the pressure plate 400 is used to block the rise of the pallet 100 when the unlocking buckle device 200 lifts the lock buckle 120.

[0080] Fig.12 A schematic diagram of another unlocking buckle mechanism provided by an exemplary embodiment of the present application is shown. Fig.12 As shown, the unlocking buckle mechanism includes a tray 100, an unlocking buckle device 200, a second driving device 300, and a pressure plate 400. During the operation of the mechanism, after the tray 100 carrying the products is conveyed to the workbench by the conveyor, the unlocking buckle process begins: first, the second driving device 300 controls the unlocking buckle device 200 to lift upward, thereby driving the tray 100 to lift upward. After the upper surface of the tray 100 contacts the pressure plate 400, the unlocking buckle device 200 continues to lift to a target height, so as to lift the lock block of the lock buckle to a target height through the unlocking buckle device 200, so that a certain distance is maintained between the lower surface of the lock block and the upper surface of the tray 100, and the second driving device 300 is stopped; thereafter, the lever is driven by the rotating shaft of the unlocking buckle device 200 to rotate the protrusion on the lock buckle, thereby driving the lock block to rotate through the lock block shaft, so as to realize an automated unlocking buckle operation through the unlocking buckle device 200.

[0081] In a possible implementation, the base plate 210 of the unlocking buckle device 200 is also provided with a tray positioning pin, such as Figure 3 or Figure 5 As shown, the tray positioning pin can be arranged on the upper plane of the base plate 210 of the unlocking buckle device 200, and is used to position and fix the tray 100 when the unlocking buckle device 200 enters, so as to ensure the accuracy and stability of subsequent operations.

[0082] In summary, the unlocking buckle mechanism provided in the embodiment of the present application includes: a tray, and an unlocking buckle device; wherein, a receiving groove for accommodating products is provided on the tray, and a plurality of locks are arranged around the receiving groove on the tray, the lock includes a lock shaft, a lock block and a protrusion, the lock shaft passes through the tray, the lock block is provided on the structure where the lock shaft is located above the tray, and the protrusion is provided on the structure where the lock shaft is located below the tray, and the protrusion is used to drive the lock shaft and the lock block to rotate; the unlocking buckle device is arranged below the tray, including a base plate and an unlocking buckle assembly corresponding to each lock, the unlocking buckle assembly including a lever arranged on a plane at one end of a rotating shaft, the rotating shaft of each unlocking buckle assembly drives the lever to rotate the protrusion in the corresponding lock to drive the lock shaft to rotate the lock block, thereby locking the lock or unlocking the lock; the setting of the unlocking buckle mechanism can be flexibly adapted to the application scenarios of multiple locks, and has good versatility while realizing the automation of the unlocking buckle.

[0083] In addition, by setting the blocking block, the lock buckle can stay in a more accurate locking position in the scenario of locking the lock buckle, thereby improving the locking effect of the lock buckle.
