[0041] Combine the following Figure 1-Figure 11 , describing the unlocking buckle mechanism provided in an embodiment of the present application.

[0042] 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;

[0043] 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;

[0044] 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 and a lock block 122, and the lock block 122 rotates around the lock shaft 121;

[0045] 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 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, 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;

[0046] When the lock buckle is locked, the rotating shaft of each unlocking buckle component drives the lever to rotate the corresponding locking block until the locking block rotates to the locking position corresponding to the receiving slot 110; when the lock buckle is unlocked, the rotating shaft of each unlocking buckle component drives the lever to rotate the corresponding locking block until the locking block rotates to the unlocking position corresponding to the receiving slot 110.

[0047] 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 washing pallet, a coating pallet, etc. The present application does not limit the type of pallet.

[0048] A plurality of lock buckles 120 are arranged around the receiving groove 110, and these lock buckles 120 are composed of a lock buckle shaft 121 and a lock block 122. The lock block 122 is hinged with the lock buckle shaft 121 and can be rotated around the shaft, thereby realizing the actions of locking and unlocking the lock buckle under the action of the unlocking buckle device; wherein, locking the lock buckle 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, forming a barrier to prevent the product from sliding or popping out; unlocking the lock buckle refers to rotating the lock block to another angle range so that the lock block no longer constrains the product, which is convenient for manual or automatic taking and placing.

[0049] The unlocking buckle device 200 includes a base plate 210, which is used to provide 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, and the length of the lever 221 enables the lever 221 to contact the locking block 122 of the lock buckle 120, so as to drive the lever 221 to control the rotation of the locking block 122 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 locking block to the locking position to fix the product, wherein the locking position may refer to the intersection of the locking block 122 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 locking block to the unlocking position to release the product, wherein the unlocking position refers to the non-intersection of the locking block 122 with the edge of the receiving groove 110.

[0050] 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.

[0051] To summarize, the unlocking buckle mechanism provided in the embodiment of the present application comprises: a tray, and an unlocking buckle device; wherein, a receiving slot for accommodating products is provided on the tray, and a plurality of locks that can rotate around the lock shaft are arranged around the receiving slot on the tray, and the unlocking buckle device comprises an unlocking buckle assembly corresponding to each lock, and the unlocking buckle assembly comprises a lever connected to a rotating shaft, and the rotating shaft of each unlocking buckle assembly drives the lever to rotate and the locking block in the corresponding lock rotates around the lock shaft. 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.

[0052] 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;

[0053] The tray 100 is provided with a receiving slot 110 for receiving products, and a plurality of locks 120 are arranged around the receiving slot 110. The locks 120 include a lock shaft 121 and a lock block 122. The lock block 122 rotates around the lock shaft 121.

[0054] The unlocking buckle device 200 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.

[0055] In one possible implementation, the rotating shaft 222 of each unlocking buckle assembly 220 is aligned 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 to ensure that the unlocking buckle assembly 220 can accurately interact with the locking buckle 120. The alignment setting can also ensure that the force transmission direction is optimized when rotating the locking block, reducing unnecessary friction and wear, and ensuring smooth unlocking buckle action.

[0056] In one possible implementation, one end of the rotating shaft of each locking buckle assembly connected to the base plate 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 operating power of each independent driving device, and the rotation state includes whether to rotate and the rotation rate.

[0057] 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 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; in this case, by controlling the start and stop and the working efficiency of the first driving device, the rotation state of all the unlocking buckle assemblies connected by the synchronous belt can be controlled, and the consistency of the rotation state of each unlocking buckle assembly can be ensured; the first driving 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 driving device.

[0058] 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.

[0059] In a possible implementation, the unlocking buckle device 200 is connected to a second driving device 300, and the second driving device 300 is arranged above the unlocking buckle device, and the second driving device 300 is used to control the lifting and lowering of the unlocking buckle device 200; Figure 5 As shown, one end of the second driving device 300 can be fixed on Figure 1 On the bracket shown, 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 and the locking block 122 can contact in the vertical direction.

[0060] In a possible implementation, the mechanism includes a flat pressing assembly corresponding to each locking position, the flat pressing assembly includes a spring and a push rod, and the push rod is connected to the lower plane of the base plate through the spring;

[0061] During the descending process of the unlocking buckle mechanism, the push rod contacts and flattens the product corresponding to the locking position.

[0062] Figure 6 Another partial schematic diagram of an unlocking buckle mechanism provided by an exemplary embodiment of the present application is shown. Figure 6 As shown, a flattening assembly 240 is provided on the lower plane of the base plate 210 corresponding to the lock position of each lock buckle, and the flattening assembly 240 includes a spring 241 and a push rod 242, wherein the overall length of the flattening assembly 240 is longer than the length of the unlocking buckle assembly 220 below the base plate 210, so as to ensure that the push rod 242 first contacts the product and flattens the product during the descent of the unlocking buckle device 200 under the action of the second driving device, and the spring 241 is used to play a buffering role to avoid damage to the product caused by excessive downward pressure; further, one end of the push rod 242 where it connects with the product can adopt a buffering material, such as rubber material, silicone material, etc., to avoid damage to the product surface.

[0063] Based on the above-mentioned unlocking buckle mechanism, during the application process, the unlocking buckle device 200 is suspended above 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 locking block 122 of the lock buckle 120 rotate around the lock buckle shaft 121 under the drive of the rotating shaft 222; wherein, when the lock buckle is locked, the rotating shaft of each unlocking buckle component drives the lever to rotate the corresponding locking block until the locking block rotates to the locking position corresponding to the accommodating groove 110; when the lock buckle is unlocked, the rotating shaft of each unlocking buckle component drives the lever to rotate the corresponding locking block until the locking block rotates to the unlocking position corresponding to the accommodating groove 110.

[0064] In a possible implementation, the lock block 122 may be equipped with a position sensor. Figure 2 The 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.

[0065] 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.

[0066] To summarize, the unlocking buckle mechanism provided in the embodiment of the present application comprises: a tray, and an unlocking buckle device; wherein, a receiving slot for accommodating products is provided on the tray, and a plurality of locks that can rotate around the lock shaft are arranged around the receiving slot on the tray, and the unlocking buckle device comprises an unlocking buckle assembly corresponding to each lock, and the unlocking buckle assembly comprises a lever connected to a rotating shaft, and the rotating shaft of each unlocking buckle assembly drives the lever to rotate and the locking block in the corresponding lock rotates around the lock shaft. 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.

[0067] 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 mechanism includes a blocking assembly corresponding to each buckle to block the buckle during its rotation so that the 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;

[0068] The tray 100 is provided with a receiving slot 110 for receiving products, and a plurality of locks 120 are arranged around the receiving slot 110. The locks 120 include a lock shaft 121 and a lock block 122. The lock block 122 rotates around the lock shaft 121.

[0069] The unlocking buckle device 200 includes a base plate 210 and unlocking buckle components 220 corresponding to each lock buckle, the unlocking buckle component 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, and the blocking component is arranged on the lower plane of the base plate;

[0070] In addition, if Figure 7 As shown, the mechanism includes a blocking assembly 250 corresponding to each lock buckle 120, and the blocking assembly 250 is configured on the lower plane of the base plate 210;

[0071] The blocking assembly 250 includes a blocking rod 251 ; the blocking rod 251 is located on the rotation path of the locking block 122 , so that the locking block 122 rotates to a locking position corresponding to the receiving slot 110 .

[0072] The blocking assembly 250 is disposed on the first plane side of the lock block 122. In this case, when the lock is locked, the rotation direction of the shaft 222 is from the second plane to the first plane, and when the lock is unlocked, the rotation direction of the shaft 222 is from the first plane to the second plane; that is, under the action of the blocking assembly, the rotation direction of the shaft when the lock is locked is opposite to the rotation direction of the shaft when the lock is unlocked. Figure 5 Taking the entry position of the blocking assembly as an example, in the process of locking the lock, the rotating shaft 222 drives the lever 221 to rotate clockwise, and drives the locking block 122 to rotate clockwise around the lock shaft 121. When the locking block 122 rotates to the position of the blocking rod 251 of the blocking assembly 250, it will be blocked by the blocking rod 251. Figure 7 As shown, the lock is currently in a locked state; optionally, a collision sensor can be configured on the blocking rod 251 or the lock block 122. After the collision sensor detects that the blocking rod 251 collides with the lock block 122, it can instruct the first drive 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 drive device; in the process of unlocking the lock, the rotating shaft 222 drives the lever 221 to rotate counterclockwise, and drives the lock block 122 to rotate counterclockwise around the lock shaft, so that the lock block 122 is away from the blocking rod 251, Figure 8 A schematic diagram showing a lock unlocking state provided by an exemplary embodiment of the present application is shown in FIG. Figure 8As shown, driven by the lever 221, the lock block 122 is rotated in the direction away from the blocking rod 251 until it reaches the unlocked position; optionally, a position sensor can 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.

[0073] In a possible implementation, a cam 223 is provided on the rotating shaft 222, and the blocking assembly 250 further includes a spring 252, a slide rail 253 and a slider 254; one end of the blocking rod 251 is connected to the lower plane of the slider 254;

[0074] The slider 254 moves along the slide rail 253 and contacts the surface of the cam 223 under the action of the spring 252;

[0075] As the rotating shaft 222 rotates, the distance between the slider 254 and the rotating shaft 222 changes, driving the distance between the blocking rod 251 and the rotating shaft 222 to change.

[0076] Fig. 9 A schematic diagram of a cam provided by an exemplary embodiment of the present application is shown. Fig. 9As shown, there is a difference in the distance between the surface of the cam 223 and the center. Therefore, during the rotation of the shaft 222, different surfaces of the cam 223 will contact the slider 254, so that the distance between the slider 254 and the shaft 222 changes, thereby driving the distance between the blocking rod 251 and the shaft 222 to change; further, when the slider 254 contacts the protruding range of the surface of the cam 223, the distance between the blocking rod 251 and the shaft 222 is greater than the distance between the driving rod 221 and the shaft 222, so that the driving rod 221 can pass through the position where the blocking rod 251 is located, avoiding the blocking rod from blocking the driving rod; and when the driving rod crosses the blocking rod, the blocking rod is driven by the slider to approach the shaft, so as to play a role in limiting the lock buckle during the process of locking the lock buckle. If the lock buckle 120 is not clamped between the push rod 221 and the blocking rod 251, during the rotation of the shaft 222, the surface of the cam 223 on the shaft 222 that is in the protruding range contacts the slider 254, the slider 254 moves away from the shaft 222, and the distance between the two increases, so that the push rod 221 can pass the position of the blocking rod 251; thereafter, the surface of the cam 223 on the shaft 222 that is in the non-protruding range contacts the slider 254, the slider 254 moves closer to the shaft 222, and the distance between the two decreases, so that the blocking rod 251 is in the rotation path of the lock buckle 120, thereby limiting the lock buckle 120.

[0077] In addition, when the unlocking buckle device 200 is driven to descend by the second driving device 300, the lever 221 and the blocking rod 251 may interfere with the lock buckle 120. During the transportation of the tray 100, the lock buckle usually swings within a swing angle (for example, 20°) under the action of the friction force on the surface of the tray 100. Therefore, in order to prevent the lever 221 from interfering with the lock buckle 120, the entry position of the lever 221 on the unlocking buckle device 200 can be located outside the rotation swing angle range relative to the unlocking position or the locking position. Schematically, Fig.10 A schematic diagram showing a lever entering a position provided by an exemplary embodiment of the present application is shown. Fig.10 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 in the locked position to avoid interference between the lever 221 and the blocking rod 251 and the lock buckle 120; correspondingly, in the scenario of unlocking the lock buckle, the lock buckle 120 is in the locked position. Since the entry position of the blocking rod 251 is relatively fixed, the interference between the lock buckle 120 and the blocking rod 251 can be avoided by manually adjusting the position of the lock buckle 120, and the lever 221 can enter in the unlocked position to avoid interference with the lock buckle 120.

[0078] In another possible implementation, the blocking rod 251 is a telescopic structure. In this case, during the descent of the unlocking buckle device 200, the blocking rod 251 is in a retracted state to avoid interference between the blocking rod 251 and the lock buckle 120; after the unlocking buckle device 200 enters the working state, the blocking rod 251 is in an extended state to limit the lock buckle 120.

[0079] To summarize, the unlocking buckle mechanism provided in the embodiment of the present application comprises: a tray, and an unlocking buckle device; wherein, a receiving slot for accommodating products is provided on the tray, and a plurality of locks that can rotate around the lock shaft are arranged around the receiving slot on the tray, and the unlocking buckle device comprises an unlocking buckle assembly corresponding to each lock, and the unlocking buckle assembly comprises a lever connected to a rotating shaft, and the rotating shaft of each unlocking buckle assembly drives the lever to rotate and the locking block in the corresponding lock rotates around the lock shaft. 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.

[0080] In addition, by setting the blocking component, in the scenario of locking the lock buckle, the lock buckle can stay in a more accurate locking position, thereby improving the locking effect of the lock buckle.

[0081] To further illustrate the unlocking buckle mechanism provided by the present application, Fig.11 Also shown is a left view of an unlocking buckle mechanism provided by an exemplary embodiment of the present application.

[0082] In another possible implementation, in order to reduce the risk of the product contained in the containing groove being scratched during the unlocking process, Figures 1 to 11 Based on any of the unlocking buckle mechanisms shown, the mechanism may also include a lifting device to reduce the risk of scratching the surface of the product during the unlocking buckle process. Fig.12 Another partial schematic diagram of an unlocking buckle mechanism provided by an exemplary embodiment of the present application is shown. Fig.12 As shown, the unlocking buckle mechanism also includes a lifting device 400, which is arranged under the pallet 100. The lifting device 400 includes a lifting device plate 410 and a boss 420 corresponding to each lock buckle deployed on the lifting device plate 410, and each boss 420 is aligned with the lock buckle shaft 121 of the corresponding lock buckle 120 in the vertical direction.

[0083] The locking shaft 121 of each locking buckle 120 may be implemented in the form of a locking spring, so that it can be lifted away from the upper surface of the tray 100 under the action of the boss 420 while remaining connected to the tray 100 .

[0084] The lifting device 400 is used to lift upward before the unlocking buckle device 200 descends, until each boss 420 contacts the corresponding lock shaft 121 of the lock 120 and lifts the lock 120 to the target height; so that the lower surface of the lock 120 maintains a certain distance from the upper surface of the tray 100, so that when the lock 120 rotates under the action of the unlocking buckle device 200 to achieve the unlocking buckle action, it does not contact the surface of the locked product, thereby reducing the risk of the lock scratching the product surface during the unlocking buckle process; wherein, the value of the target height can be set on the basis of ensuring the fixing strength of the product while avoiding contact with the product surface, for example, it can be 1mm to 3mm, and the value of the target height can be set based on the working conditions, and the present application does not impose any restrictions on this.

[0085] Since the lock shaft 121 of the lock 120 is connected to the pallet 100, the pallet 100 may be lifted upward during the process of the lifting device 400 lifting the lock 120. In this case, in order to achieve the effect of maintaining a certain distance between the lower surface of the lock and the upper surface of the pallet, the mechanism also includes a plurality of pressure plates 500. The pressure plates 500 are fixedly arranged on the frame of the mechanism and are located above the pallet 100. The protruding portion thereof partially overlaps with the pallet 100 in the vertical direction, and is used to prevent the pallet 100 from continuing to rise during the process of the pallet 100 rising under the action of the lifting device 400.

[0086] At this time, when the lifting device 400 acts upward, each boss 420 on the lifting device plate 410 contacts the bottom of the corresponding lock shaft 121 of the lock 120, and drives the tray 100 to rise. When the upper surface of the tray 100 contacts the pressure plate 500, the tray 100 stops lifting under the blocking action of the pressure plate 500. After the lock shaft 121 of the lock 120 continues to rise to the target distance under the action of the corresponding boss 420, the lifting device 400 stops lifting, so that the lower surface of the lock keeps a certain distance from the upper surface of the tray, so that the lock does not contact the locked product during the unlocking process, thereby reducing the risk of scratching the product. After the lifting device 400 stops lifting, the unlocking device 200 descends to the corresponding position under the action of the second drive device 300 to perform the unlocking operation. This process can be referred to as follows. Figures 1 to 11 The relevant contents of the illustrated embodiment will not be repeated here.

[0087] Fig.13 A schematic diagram of another unlocking buckle mechanism provided by an exemplary embodiment of the present application is shown. Fig.13As shown, the unlocking buckle mechanism includes a tray 100, an unlocking buckle device 200, a second driving device 300, a lifting device 400, a pressing plate 500, and a third driving device 600 disposed below the lifting device 400, the third driving device 600 is used for lifting and lowering the lifting device 400, as shown in FIG. Fig.12 As shown, during the operation of the mechanism, the third driving device 600 is first used to control the lifting device 400 to lift upward, thereby driving the pallet 100 to lift upward. After the upper surface of the pallet 100 contacts the pressure plate 500, the lifting device 400 continues to lift to the target height, so as to lift the lock shaft of the lock to the target height through the convex column on the lifting device 400, so as to achieve the purpose of lifting the lock on the pallet 100 to the target height, so that the lower surface of the lock is at a certain distance from the upper surface of the pallet, and the third driving device 600 is stopped; thereafter, the unlocking buckle device 200 is controlled by the second driving device 300 to descend to a position where the lever and the lock block of the lock can contact in the vertical direction, so as to realize the automatic unlocking buckle operation through the unlocking buckle device 200.

[0088] It should be noted that the mechanism may also include a tray positioning pin. Figures 1 to 11 In the case of the embodiment shown, Figure 3 As shown, the tray positioning pin can be arranged on the lower plane of the base plate 210 of the unlocking buckle device 200 to position and fix the tray 100; Figures 12 to 13 In the case of the illustrated embodiment, the pallet locating pins may be disposed on an upper surface of a lifting device plate 410 of the lifting device 400 .
