Description

Technical Field

[0001] The present application relates to the technical field of depalletizing, and in particular to a depalletizing device. Background Art

[0002] Generally, in production operations, due to the limitation of site area, materials need to be stacked up layer by layer most of the time. For example, some transport racks are stacked by multi-layer frames to reduce the space occupied. The process of disassembling stacked materials (such as transport racks) can also be called destacking. Specifically, the manufacturer uses destacking equipment to clamp and take out the materials layer by layer, and then places them at other storage points and releases them. Then the destacking equipment is controlled to return to the original position to clamp and take out the materials layer by layer again. After multiple process cycles, the final disassembly of the stacked materials is completed.

[0003] In the related art, the depalletizing equipment is provided with a linear drive assembly to control the lowering of the gripper or suction cup and other clamping parts to achieve the clamping and lifting of the surface materials.

DETAILED DESCRIPTION

[0037] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0038] See also Figure 1 , Figure 1 The structure diagram of the depalletizing device 100 in one embodiment of the present application is shown. The depalletizing device 100 provided in one embodiment of the present application includes a support frame 110, a guide assembly 120, a drive assembly 130 and a locking assembly 140. The guide assembly 120, the drive assembly 130 and the locking assembly 140 are all installed in the support frame 110.

[0039] Specifically, Figure 2 As shown, the guide assembly 120 is extended along the height direction X of the support frame 110. The guide assembly 120 includes a first guide member 121 and a second guide member 122. The first guide member 121 and the second guide member 122 are staggered along the width direction Y of the support frame 110, the first guide member 121 is arranged close to the material, and the second guide member 122 is arranged away from the material (such as a transport platform, etc.) relative to the first guide member 121. The first guide member 121 and the second guide member 122 can be guide plates, guide rails, etc.

[0040] like Figure 3As shown, the driving assembly 130 is connected to the locking assembly 140, and the locking assembly 140 moves along the height direction X of the support frame under the driving of the driving assembly 130. When the locking assembly 140 moves relative to the support frame 110 under the driving of the driving assembly 130, it can guide and switch between the first guide member 121 and the second guide member 122, so that the locking assembly 140 has a first motion state and a second motion state.

[0041] It can be understood that, since the first guide member 121 and the second guide member 122 are staggered in the width direction Y, when the locking assembly 140 and the first guide member 121 cooperate, the locking assembly 140 is arranged in a direction close to the material in the width direction Y, and the locking assembly 140 is in the first motion state. When the locking assembly 140 is in the first motion state, the locking assembly 140 can be locked with the material.

[0042] When the locking assembly 140 and the second guide member 122 cooperate, the locking assembly 140 is arranged in a direction away from the material in the width direction Y, and the locking assembly 140 is in the second motion state. When the locking assembly 140 is in the second motion state, the locking assembly 140 is spaced apart from the material, so that the locking assembly 140 and the material are in an unlocked state.

[0043] For ease of understanding, a detailed description is given below in conjunction with an example usage scenario of the depalletizing device 100 .

[0044] Assume that the second guide member 122 is disposed close to the bottom of the supporting frame 110 , and the first guide member 121 is disposed away from the bottom of the supporting frame 110 relative to the second guide member 122 .

[0045] When the depalletizing device 100 needs to disassemble the material, the driving component 130 drives the locking component 140 to move from the second guide member 122 to the first guide member 121, so that the locking component 140 gradually changes from an unlocked state spaced apart from the material to a locked state connected to the material, and the locking component 140 continues to move on the first guide member 121 to achieve fixation with the material through the locking component 140. At this time, the upper layer of material is separated from the lower layer of material, and the lower layer of material can be moved away to achieve disassembly of the lower layer of material.

[0046] After the lower layer of materials is disassembled, the driving assembly 130 can drive the locking assembly 140 to move from the first guide member 121 to the second guide member 122, so that the locking assembly 140 is changed from a locked state connected to the material to an unlocked state spaced apart from the material, and the locking assembly 140 is moved on the second guide member 122, so that the locking assembly 140 is completely unlocked and separated from the upper layer of materials. At this time, the upper layer of materials can be moved away. Through the above operations, the upper layer of materials and the lower layer of materials can be completely separated and disassembled.

[0047] In this way, when the driving component 130 drives the locking component 140 to move along the height direction X, since the locking component 140 can be guided and cooperated on the guide component 120, the position of the locking component 140 in the width direction Y can be switched based on the different settings of the first guide member 121 and the second guide member 122 in the width direction Y, and then the mechanical locking component 140 and the material locking and unlocking are switched. There is no need to set other linear driving components in the width direction Y, which is beneficial to saving the installation space of the destacking device 100 and reducing the processing cost of the destacking device 100.

[0048] It should be noted that the number of drive components 130 in the above embodiment can be one, two, three or more, etc., and no excessive restrictions are imposed here. Furthermore, the guide cooperation between the locking component 140 and the guide component 120 can be, but not limited to, abutment guide, and can also be limited sliding guide through guide rails, magnetic attraction, etc. In addition, the first guide member 121 and the second guide member 122 can be connected or spaced apart.

[0049] In one example, the first guide 121 and the second guide 122 are arranged at intervals. The locking assembly 140 and the guide assembly 120 are magnetically guided. Specifically, when the locking assembly 140 is in the first motion state, the first guide 121 is in a magnetized state, and the second guide 122 is in a non-magnetized state, so that the locking assembly 140 and the first guide 121 are magnetically guided. When the locking assembly 140 switches from the first motion state to the second motion state, the first guide 121 is in a non-magnetized state, and the second guide 122 is in a magnetized state. Due to the action of the magnetic force, the locking assembly 140 is magnetically fixed by the second guide 122, and the locking assembly 140 is guided and matched on the second guide 122 by the drive assembly 130. In this embodiment, the drive assembly 130 can be a combination of components such as a combination of a flexible transmission member and a motor. The magnetic force of the first guide 121 and the second guide 122 can be provided by an electromagnet, a permanent magnet, etc., and no excessive restrictions are made here.

[0050] In another example, Figure 4As shown, the first guide member 121 and the second guide member 122 are connected. Specifically, the guide assembly 120 also includes a third guide member 123. One end of the third guide member 123 is connected to the first guide member 121, and the other end is connected to the second guide member 122. The locking assembly 140 is guided and matched with the third guide member 123, so that the locking assembly 140 switches between the first motion state and the second motion state.

[0051] In this way, through the guiding cooperation between the locking assembly 140 and the third guide member 123, the locking assembly 140 can complete the switching between the first motion state and the second motion state on the third guide member 123, thereby improving the movement stability of the locking assembly 140 when switching between the first motion state and the second motion state, thereby improving the movement stability of the locking assembly 140 and the material when locking and loosening.

[0052] Furthermore, when the first guide 121 and the second guide 122 are arranged at intervals, the locking assembly 140 itself needs to switch between the first guide 121 and the second guide 122. At this time, the gap between the first guide 121 and the second guide 122 cannot be set too large, resulting in a relatively limited range of motion of the locking assembly 140 when locking and unlocking. The arrangement of the third guide 123 allows the staggered gap between the first guide 121 and the second guide 122 to be set large enough, so that the active spacing of the locking assembly 140 when switching between the first motion state and the second motion state is large enough, and even if the installation spacing between the material and the first guide 121 is large, the locking assembly 140 can still maintain the locking and unlocking cooperation with the material, which broadens the use scenario of the destacking device 100.

[0053] It should be noted that when the locking assembly 140 is in the first motion state and the second motion state, the motion trajectory of the locking assembly 140 can be a linear motion trajectory or a curved motion trajectory.

[0054] In combination with any of the above embodiments of the locking assembly 140, Figure 5 As shown, the locking assembly 140 includes a rotating body 141, a locking member 142, and a guide matching member 143. The rotating body 141 is provided with a first side 1411 and a second side 1412 opposite to each other along the width direction Y, and the first side 1411 is arranged away from the second guide member 122. The second side 1412 is arranged close to the second guide member 122. At least part of the locking member 142 is protruded from the first side 1411, so that the locking member 142 can be protruded from the second side 1412 with at least part of the guide matching member 143.

[0055] Furthermore, the rotating body 141 is drivingly connected to the driving assembly 130 , so that the driving assembly 130 drives the locking member 142 and the guide fitting member 143 to move synchronously along the height direction X through the rotating body 141 . One end of the rotating body 141 is rotationally matched with the driving assembly 130 , and the guide fitting member 143 is guide-matched with the guide assembly 120 .

[0056] It can be understood that one end of the rotating body 141 is rotatably matched with the driving assembly 130, and the point where the rotating body 141 is connected to the driving assembly 130 is equivalent to the fulcrum. Since the first guide member 121 and the second guide member 122 are staggered in the width direction Y, when the guide matching member 143 moves to the third guide member 123 for guiding matching, the guide matching member 143 is gradually lifted on the third guide member 123, and the lifting direction is the moving direction close to the material. The second side 1412 of the rotating body 141 is subjected to force, so that the other end of the rotating body 141 is rotated and lifted along the moving direction close to the material, so that the other end of the rotating body 141 is rotated and switched between at least the first position and the second position. When the rotating body 141 is in the first position, the locking member 142 is locked and matched with the material. When the rotating body 141 is in the second position, the locking member 142 is spaced apart from the material.

[0057] In this way, by the rotational coordination between the rotating body 141 and the driving assembly 130, and using the guide coordination member 143 as the force-bearing part, a rotation vector is provided for the rotation of the rotating body 141. Compared with realizing rotation through a connecting rod assembly, etc., this design has a simpler structure, is more convenient to process, and is conducive to improving processing efficiency.

[0058] In addition, the material is provided with a clamping portion (such as a side wall, a socket, etc.). When the locking assembly 140 is hooked and locked with the clamping portion of the material, the rotation of the rotating body 141 makes the movement trajectory of the locking member 142 present an arc curve, and then when the locking member 142 is clamped and fixed with the material, it can be inserted obliquely into the clamping portion of the material from a low point, enter the clamping portion of the material and then gradually hook up to achieve abutment and clamping between the material and the locking member 142, avoiding excessive obstruction of the locking member 142 by other parts of the material (such as the side wall of the clamping portion), thereby improving the clamping effect of the locking member 142 and the material, and there is no need to spend a lot of time on horizontal alignment, thereby improving the destacking efficiency.

[0059] Further, in one embodiment, see Figure 4 As shown, the third guide member 123 is provided with an inclined surface structure 1231. One end of the inclined surface structure 1231 is connected to the first guide member 121, and the other end is connected to the second guide member 122. In this way, the inclined surface structure 1231 serves as a connection between the first guide member 121 and the second guide member 122, and has a simple structure and is convenient to set up.

[0060] It should be noted that the inclined surface structure 1231 can be, but is not limited to, any combination of an inclined straight surface, an inclined convex surface, or an inclined concave surface, and no further limitations are given herein.

[0061] In another embodiment, the arc-shaped motion trajectory of the locking member 142 can also be realized in the following manner: specifically, the third guide member 123 is provided with a convex structure, and the convex structure is protruded along the first direction. The first direction is the direction from the second guide member 122 to the first guide member 121, and the first direction is parallel to the width direction Y. It can be understood that when the guide matching member 143 is in the guide matching of the convex structure, the moving trajectory of the guide matching member 143 is set in a curve, so that the motion trajectory of the locking assembly 140 is also set in a curve.

[0062] Thus, accordingly, when the movement trajectory of the locking assembly 140 is set in a curve, it is convenient for the locking assembly 140 and the material to gradually transition from unlocking to locking, that is, gradually penetrate from the bottom of the clamping part of the material to the clamping part, so as to realize the locking of the material by the locking assembly 140, avoid excessive obstruction of the locking member 142 by other parts of the material, optimize the clamping effect of the locking member 142 and the material, and do not need to spend a lot of time on horizontally aligning the clamping part, thereby improving the destacking efficiency.

[0063] In combination with any of the above embodiments of the rotating body 141, Figure 5 The locking assembly 140 further includes a transmission body 144. One end of the transmission body 144 is drivingly connected to the driving assembly 130, and the transmission body 144 is provided with at least two first matching holes 1441 arranged at intervals. The rotating body 141 and the first matching holes 1441 are rotatably arranged.

[0064] In a specific embodiment, the locking assembly 140 also includes a first rotating member. The first rotating member is fixedly disposed on a side of the rotating body 141 away from the locking member 142, and the first rotating member is inserted into at least two first matching holes 1441, so that the rotating body 141 can be rotationally matched with the first matching holes 1441 through the first rotating member. That is, in this embodiment, when a rotating member is inserted into at least two first matching holes 1441, the first rotating member is rotated relative to the first matching hole 1441 to drive the rotating body 141 to rotate and switch between the first position and the second position. In this way, the arrangement of the first rotating member is simple in structure and easy to obtain, which is conducive to simplifying the processing procedures of the destacking device 100. Among them, the first rotating member can be a rotating shaft, a rotating rod, etc.

[0065] In another specific embodiment, Figure 3The destacking device 100 includes at least two locking assemblies 140. The at least two locking assemblies 140 are spaced apart on the same side. A second rotating member is provided at one end of the rotating body 141 away from the locking member 142. The second rotating member is plugged into and rotated with the first matching hole 1441 one by one, so that the rotating body 141 is rotated with the transmission body 144 through the second rotating member. The second rotating member can be a rotating shaft, a rotating column, etc.

[0066] In this way, since the second rotating member and the first matching hole 1441 are matched one-to-one, even if the spacing between the two locking components 140 of the destacking devices 100 of different sizes is different, there is no need to use first rotating members of different sizes to connect the first matching holes 1441 of different spacings to achieve rotation. It is only necessary to install and match the original second rotating member with the first matching hole 1441, which is beneficial to improving the adaptation scenarios of the destacking device 100 in this embodiment, and there is no need to produce spare parts such as first rotating members of various sizes, thereby improving production efficiency.

[0067] In some embodiments, Figure 5 The locking member 142 includes a first mounting body 1421 and a hook body 1422. One end of the first mounting body 1421 is connected to the rotating body 141, and the hook body 1422 is arranged near the other end of the first mounting body 1421, and the hook body 1422 is convexly arranged on the first mounting body 1421. The material is provided with a clamping portion. Among them, the hook body 1422 can abut against the side wall of the clamping portion to limit the position, so that the locking assembly 140 is locked and matched with the material.

[0068] That is, in this embodiment, the locking of the locking assembly 140 and the material is achieved by the abutment and cooperation between the hook claw body 1422 and the clamping portion. Assuming that the clamping portion is a clamping recess or a clamping hole, the hook claw body 1422 can be inserted into the clamping recess so that the hook claw body 1422 is fixed to the material. As the driving assembly 130 drives the locking assembly 140 to move along the first guide member 121, the side of the hook claw body 1422 can abut and cooperate with the inner side wall of the clamping recess to achieve the locking of the material on the locking member 142, and then achieve the synchronous movement of the material and the locking assembly 140. Assuming that the clamping portion is the bottom surface of the material, the hook claw body 1422 can directly hook up the bottom surface of the material, so that the bottom surface of the material abuts and cooperates with the hook claw body 1422, so that the hook claw body 1422 is fixed to the clamping portion, and then achieves the synchronous disassembly of the locking assembly 140 and the layer of material.

[0069] In this way, the hook body 1422 is provided to achieve abutment locking or plug locking of the material, which has a simple structure and is easy to process. Different from designs such as pneumatic gripping, it is beneficial to reduce the processing cost of the depalletizing device 100.

[0070] It should be noted that the hook body 1422 is installed to the first installation body 1421, and the hook body 1422 can be vertically arranged with respect to the first installation body 1421, or can be inclined with respect to the first installation body 1421, which is not further limited here.

[0071] In other embodiments, Figure 5 The hook body 1422 is provided with a first end 1422a and a second end 1422b. The first end 1422a is bent and connected to one end of the first installation body 1421. The first end 1422a to the second end 1422b are arranged in a direction away from the material.

[0072] It can be understood that the hook body 1422 is tilted, so that when the hook body 1422 is inserted into the clamping part, the obstruction of the clamping part in the height direction X can be reduced, which is convenient for improving the locking and matching efficiency between the hook body 1422 and the material. Further, the tilt direction of the hook body 1422 is set in a direction gradually away from the material, so that when the driving component 130 drives the locking component 140 to move along the direction of the first guide member 121, the abutment and matching excitation between the material and the hook body 1422 is reduced, which is convenient for the material to quickly move synchronously with the locking component 140, and it is not easy to fall off, thereby improving the locking stability of the locking component 140 locking the material.

[0073] In addition, the first end 1422a to the second end 1422b are arranged in a direction away from the material, which is conducive to improving the disassembly accuracy of the layered material by the depalletizing device 100. Specifically, the position of the third guide member 123 determines that the depalletizing device 100 disassembles the material corresponding to the position. Generally, multi-layer materials (such as a transport platform) in a production workshop may be formed by stacking layered materials (such as a frame layer) of different widths. It is assumed that the material is provided with a first layer, a second layer and a third layer from top to bottom. And the width of the third layer is greater than the first layer and the second layer. The position of the third layer is arranged corresponding to the second guide member 122. The second layer is arranged corresponding to the third guide member 123, and the first layer is arranged corresponding to the first guide member 121. At this time, the hook claw body 1422 arranged vertically or inclined from the first end 1422a to the second end 1422b in the direction close to the material may be hooked and locked with the third layer, thereby disassembling the third layer, so that the three layers of materials (such as the entire transport platform) are locked and lifted, and the materials cannot be disassembled.

[0074] When the hook body 1422 is arranged from the first end 1422a to the second end 1422b in a direction away from the material, when the hook body 1422 moves vertically along the height direction X of the second guide member 122, the second end 1422b of the hook body 1422 always remains away from the third layer of material, and the second end 1422b cannot hook and lock the third layer until the locking assembly 140 moves to the second layer. Only then can the second end 1422b of the hook body 1422 rotate in a direction close to the second layer, thereby locking the second layer, and then achieving synchronous lifting of the second layer and the first layer, so as to facilitate the removal and disassembly of the third layer and achieve accurate destacking.

[0075] Accordingly, in some embodiments, the depalletizing position of the depalletizing device 100 can also be adjusted by the setting position of the third guide member 123. Specifically, the depalletizing device 100 further includes a height adjustment member, which is connected to the guide assembly 120, so that the guide assembly 120 can adjust the position of the guide assembly 120 in the height direction X through the height adjustment member. In this way, the position of the third guide member 123 can be adjusted through the height adjustment member, so that materials at different levels can be accurately disassembled, thereby improving the accuracy of disassembly.

[0076] It should be noted that the height adjustment member may be, but is not limited to, a Z-shaped height adjustment frame, a pull-out telescopic rod, etc., and no excessive restrictions are imposed herein.

[0077] In addition, in another embodiment, Figure 2 The guide fitting 143 includes a second mounting body 1431 and a rolling shaft 1432. The second mounting body 1431 is connected to the second side 1412. The rolling shaft 1432 is inserted into the second mounting body 1431, and the rolling shaft 1432 is used to roll and abut against the guide assembly 120, so that the locking assembly 140 is guided and matched with the guide assembly 120 through the rolling shaft 1432.

[0078] In this way, the rolling shaft 1432 and the guide assembly 120 are rolled and abutted to achieve guidance, which is different from the direct sliding friction abutment. The rolling abutment method is beneficial to reducing the guiding resistance between the locking assembly 140 and the guide assembly 120, thereby improving the movement efficiency of the locking assembly 140 and then improving the destacking efficiency.

[0079] In order to improve the locking effect between the locking assembly 140 and the material, in other embodiments, the depalletizing device 100 includes at least two locking assemblies 140. At least two locking assemblies 140 are arranged on the same side. The third guide member 123 is connected and arranged between the at least two locking assemblies 140. It can be understood that by providing multiple locking assemblies 140, the matching area when the locking assembly 140 and the material are locked can be increased, thereby improving the locking matching effect between the locking assembly 140 and the material, and then ensuring that the material will not fall during the depalletizing process.

[0080] Furthermore, in one embodiment, the depalletizing device 100 further includes a connecting member 150. The connecting member 150 is connected and arranged between at least two locking assemblies 140. In this way, the arrangement of the connecting member 150 allows the locking assemblies 140 to be subjected to the traction force of the connecting member 150 when they move, thereby ensuring that at least two locking assemblies 140 maintain synchronous movement, thereby achieving synchronous locking and matching or unlocking and releasing of at least two locking assemblies 140 with the material, thereby improving the movement stability of the depalletizing process.

[0081] In one example, the depalletizing device 100 further includes at least two guide assemblies 120. At least two guide assemblies 120 are arranged at intervals on the same side, and at least two guide matching members 143 are arranged one-to-one with the guide assemblies 120 and the locking assemblies 140, which can be installed on the connecting member 150. In this way, by setting the guide assemblies 120 at intervals, the locking assemblies 140 can be guided and matched with the guide assemblies 120 one-to-one, and the setting size of the guide assemblies 120 can be different, which reduces the setting size of the depalletizing device 100 and helps to reduce the weight of the depalletizing device 100.

[0082] In combination with any of the above embodiments of the locking assembly 140, Figure 1 The depalletizing device 100 includes at least two driving assemblies 130. The at least two driving assemblies 130 are arranged opposite to each other along the width direction Y and are arranged on the supporting frame 110. The driving assemblies 130 are arranged in a one-to-one correspondence with the locking assemblies 140 and the guide assemblies 120. In this way, by setting at least two driving assemblies 130, the locking assemblies 140 can lock or unlock the two sides of the material in the width direction Y, so that the material can maintain a stable center of gravity when moving in the height direction X, thereby improving the disassembly stability of the material.

[0083] It should be noted that the motion trajectory of the locking assembly 140 driven by the driving assembly 130 can be a straight line or a curve, which can be determined by the different types of the driving assembly 130. For example, if the driving assembly 130 is provided with a linear guide rail, the motion trajectory of the locking assembly 140 is a straight line. On the contrary, if the driving assembly 130 is provided with a curved guide rail, the motion trajectory of the locking assembly 140 is a curve.

[0084] In combination with any of the above embodiments of the driving assembly 130, Figure 1The driving assembly 130 includes a power source 131 and a telescopic member 132. One end of the telescopic member 132 is drivingly connected to the power source 131, and the other end is connected to the locking assembly 140, so that the power source 131 drives the telescopic member 132 to drive the locking assembly 140 to telescopically move in the height direction X. In this way, through the driving cooperation between the power source 131 and the telescopic member 132, the telescopic member 132 drives the locking assembly 140 to move in a straight line when the first guide member 121 and the second guide member 122 are guided, thereby minimizing the moving distance of destacking and improving the efficiency of destacking.

[0085] The power source 131 may be, but is not limited to, a motor, a cylinder, a winding machine, etc., and the telescopic member 132 may be a spiral telescopic rod or a linear telescopic rod, etc.

[0086] In some embodiments, the power source 131 includes a cylinder. The telescopic member 132 includes a telescopic rod. The cylinder is used to drive the telescopic rod to telescopically move along the height direction X. In this way, the cylinder is used as the power source 131. Different from the motor, etc., which uses a spiral to convert into a linear telescopic drive, the cylinder directly drives the telescopic rod to telescopically move in a linear manner, which is beneficial to improving the telescopic efficiency of the telescopic rod, thereby improving the destacking efficiency.

[0087] In addition, in order to improve the movement stability of the telescopic member 132, Figure 1 In other embodiments, the depalletizing device 100 further includes a guide rail assembly 160. The guide rail assembly 160 is extended along the height direction X and is spaced apart from the guide assembly 120. The locking assembly 140 is also provided with a guide block. The guide block is guided and matched with the guide rail assembly 160, so that the locking assembly 140 is guided and matched with the guide rail assembly 160. In this way, through the sliding cooperation between the guide rail assembly 160 and the guide block, the guide rail assembly 160 can provide a moving limit for the locking assembly 140, thereby improving the movement stability of the locking assembly 140 in the process of driving the material depalletizing.

[0088] Specifically, in one example, the guide block can be arranged on the transmission body 144. In this way, unlike being directly arranged on the rotating body 141, the rotating body 141 will be pushed out when it is on the third guide member 123, so that the motion trajectory of the rotating body 141 is arc-shaped, while the motion trajectory of the transmission body 144 can be telescopically moved along the height direction X synchronously with the telescopic member 132, so that the motion trajectory of the transmission body 144 can be linear. Based on this, the guide block is arranged on the transmission body 144, so that the setting of the guide rail assembly 160 can extend along the height direction X, and then there is no need to set the guide rail assembly 160 in a partial arc shape, and it can also meet the whole process of providing a moving limit for the movement of the locking assembly 140, thereby maximizing the movement stability of the destacking.

[0089] It should be noted that the guide rail assembly 160 can be a slide groove type, a ball bearing type, etc., and no excessive restrictions are made here.

[0090] In other embodiments, the guide rail assembly 160 may be a ball guide rail. Thus, by providing the ball guide rail, the movement resistance of the guide block between the ball guide rails can be reduced, which is convenient for improving the movement efficiency of the locking assembly 140. Moreover, the balls in the ball guide rails can be used as transition pieces for wear during the sliding process, thereby reducing the scratches on the guide block and the side wall of the guide rail, which is beneficial for protecting the guide rail assembly 160 and the locking assembly 140 and extending their service life.

[0091] There may be more than one guide rail assembly 160. In some embodiments, the guide rail assembly 160 is disposed one-to-one with the guide block. When the transmission body 144 is provided with two guide blocks at intervals along the thickness direction Z of the support frame 110, two guide assemblies 120 may be disposed at intervals along the thickness direction Z, thereby improving the movement balance of the transmission body 144 and thus improving the movement stability of the locking assembly 140.
