Description

Technical Field

[0001] This application relates to the technical field of material handling equipment, and in particular to a cantilevered bidirectional linear guide telescopic hooking mechanism. Background Technology

[0002] During the assembly and production of server chassis, carrier boards need to be installed inside the chassis. In some large server chassis, the carrier boards used are relatively large, for example, the common carrier board size is 1200mm long and 550mm wide, which results in the carrier board being not only large in size but also heavy.

[0003] Currently, in server chassis assembly, to reduce the physical exertion of workers, trolleys and lifts are often used in combination to move the chassis boards, thereby reducing the degree of manual intervention. Specifically, operators typically place the chassis boards on a trolley, transport them to the chassis, and then use a lift to raise the boards to approximately the same height as the target position inside the chassis. Subsequently, operators need to manually, or with the aid of simple auxiliary rails, push the chassis boards horizontally into the chassis from the lifting platform.

[0004] In this process, to facilitate the transfer of the carrier plate from the trolley to the elevator, the existing elevator is equipped with a hooking mechanism. The hooking mechanism mainly includes a cantilevered hooking plate, a hooking component located at the front end of the hooking plate, a drive device for extending the hooking plate, and a guide component located on the elevator platform. The hooking plate extends along the guide component under the action of the drive device to hook the carrier plate. The guide component is usually a single set of linear guide rails installed on the elevator platform.

[0005] Regarding the aforementioned technologies, in existing hooking mechanisms, when the hooking plate extends to hook the carrier plate, it forms a cantilever structure. Due to the large weight of the carrier plate itself, a huge load is applied to the front end of the extended hooking plate. This directly causes the front end of the hooking plate to sag significantly after hooking the carrier plate, thus affecting the guiding nature of the hooking plate. This makes the hooking plate prone to shaking or even jamming during the retraction process after hooking the carrier plate, which affects the stability of the hooking mechanism. Summary of the Invention

[0006] This application provides a cantilevered bidirectional linear guide telescopic hooking mechanism, the purpose of which is to improve the stability of the hooking mechanism during operation.

[0007] This application provides a cantilevered bidirectional linear guide telescopic hooking mechanism with the following technical solution: A cantilevered bidirectional linear guide telescopic hooking mechanism includes a base plate, on which a hooking plate is provided, and a hooking assembly is provided at one end of the hooking plate along its own length direction; the base plate is provided with a bottom linear guide and a top slide block, and the hooking plate is provided with a top linear guide and a bottom slide block, both the bottom linear guide and the top linear guide are provided along the length direction of the hooking plate, the bottom slide block is slidably mounted on the bottom linear guide, and the top slide block is slidably mounted on the top linear guide; the base plate is also provided with a linear actuator, which is connected to the hooking plate and is used to drive the hooking plate to move along its own length direction.

[0008] By adopting the above technical solution, the hook plate can move towards the carrier plate under the action of the linear actuator, and thus the hook plate can hook the carrier plate under the action of the hook assembly, which satisfies the basic function of the hook mechanism.

[0009] Based on this, when the hook plate picks up the carrier plate, the carrier plate presses down on the front end of the hook plate, causing the front end of the hook plate to deform and bend. Since the top linear guide is set on the hook plate, it can enhance the rigidity of the hook plate, thereby reducing the amount of deformation and ensuring the stability of the hook plate structure.

[0010] The bottom rail, bottom slide, top rail, and top slide of this application work together to enhance the stability of the sliding connection between the hook plate and the base plate, thereby ensuring the guiding function of the hook plate.

[0011] Therefore, this design can reduce the deformation of the front end of the hook plate and ensure the guiding nature of the hook plate, so that the hook plate can move stably during the retraction process after hooking the carrier plate, thereby ensuring the stability of the hooking mechanism.

[0012] Optionally, the material hook assembly includes a vertical plate, the vertical plate is vertically arranged, the lower end of the vertical plate is rotatably connected to the material hook plate, and a torsion spring is provided between the vertical plate and the material hook plate, one end of the torsion spring is connected to the vertical plate, and the other end is connected to the material hook plate.

[0013] By adopting the above technical solution, the material hooking assembly, through the coordinated design of the upright plate and torsion spring, ensures that the upright plate remains vertical under the action of the torsion spring, facilitating the hooking action. When the hooking plate picks up the carrier plate, it extends towards the carrier plate. After the upright plate touches the carrier plate, the carrier plate abuts against the upright plate, causing the upright plate to rotate parallel to the hooking plate against the elastic force of the torsion spring. This prevents the upright plate from interfering with the movement of the hooking plate, allowing it to continue moving to the area below the corresponding carrier plate. When the upright plate moves to the corresponding groove on the carrier plate, it automatically rotates vertically under the action of the torsion spring, allowing it to engage with the groove and thus hooking the carrier plate. This achieves the function of the material hooking assembly, while also giving it flexibility and obstacle avoidance capabilities.

[0014] Optionally, the hook plate is spaced apart from the upright plate along its own length direction, and a mounting base is provided at one end of the hook plate facing the upright plate. The mounting base is detachably connected to the hook plate. The lower end of the upright plate is rotatably connected to the mounting base. The torsion spring is disposed between the mounting base and the upright plate, and one end of the torsion spring is connected to the upright plate and the other end is connected to the mounting base.

[0015] By adopting the above technical solution, the hook assembly can be disassembled and replaced with the hook plate based on the mounting base, thus facilitating the replacement and maintenance of the hook assembly. When the hook assembly wears out or needs to be replaced with a different type of hook assembly for different carrier plates, the corresponding hook assembly can be disassembled by removing the mounting base, and then the mounting base for the new hook assembly can be installed, thus enabling the installation of the new hook assembly. Therefore, this design simplifies the maintenance process, reduces maintenance costs, and improves the versatility and flexibility of the hook mechanism of this application.

[0016] Optionally, the hook plate has a clearance groove at one end facing the upright plate. The clearance groove passes through the hook plate vertically and is directly opposite the upright plate. When the upright plate rotates from a vertical state to a horizontal state, the upright plate rotates into the clearance groove.

[0017] By adopting the above technical solution, based on the design of the relief groove, when the hook plate picks up the carrier plate, the vertical plate can rotate to be housed in the relief groove, so that the upper surface of the hook plate is flat and without protrusions, avoiding interference of the vertical plate with the movement of the hook plate, thereby ensuring the stability of the movement of the hook plate.

[0018] Optionally, there are two bottom rails, which are arranged in parallel and spaced apart. The linear actuator is located between the two bottom rails, and the two bottom rails are symmetrically arranged on both sides of the linear actuator. There are two bottom slides, which are arranged in one-to-one correspondence with the bottom rails. The bottom slides are slidably arranged on the corresponding bottom rails.

[0019] By adopting the above technical solution, the design based on double bottom linear rails can effectively resist the lateral forces that the hook plate may experience during movement, as well as the torsional loads that may be generated due to the shift of the center of gravity of the carrier plate. Compared with a single linear rail, the double linear rail structure provides higher lateral stiffness and torsional resistance with a wider support base, thereby preventing the hook plate from horizontally swaying or twisting, and ensuring the straightness and positioning accuracy of the hook mechanism in reciprocating motion.

[0020] Optionally, there are two top linear rails, which are arranged in parallel and spaced apart. The linear actuator is located between the two top linear rails, and the two top linear rails are symmetrically arranged on both sides of the linear actuator. There are two top slides, which are arranged in one-to-one correspondence with the top linear rails. The top slides are slidably arranged on the corresponding top linear rails.

[0021] By adopting the above technical solution, based on the design of double top linear guides, firstly, the double top and double bottom linear guides work together to form a stable guide frame, which can resist combined forces and torsional loads from the vertical and horizontal directions. This further enhances the anti-eccentric load capacity and overall operational stability of the hooking mechanism, ensuring that the hook plate maintains a precise movement trajectory even under harsh working conditions such as high speed or uneven load. Secondly, the coordinated design of the double top linear guides further enhances the rigidity of the hook plate, thereby reducing the deformation of the hook plate and ensuring the stability of the hook plate's movement.

[0022] Optionally, the hook plate includes a base plate and an extension plate, the top rail and the bottom slide are both disposed on the base plate; the extension plate is disposed along the length direction of the top rail, the extension plate is slidably connected to the base plate, the hook assembly is disposed at the front end of the extension plate, a secondary driver is disposed on the base plate, the secondary driver is connected to the extension plate, and the secondary driver is used to drive the extension plate to move along its own length direction.

[0023] By adopting the above technical solution, the hook plate, through the coordinated design of the base plate, the extension plate, and the secondary actuator, allows the base plate and the extension plate to move synchronously under the action of the linear actuator; under the action of the secondary actuator, the base plate and the extension plate can move relative to each other, thus forming a two-stage telescopic structure for the hook mechanism. This design decomposes the deformation problem of a long cantilever into the superposition of the deformations of two shorter cantilevers. Based on the mechanical principle that the deflection of a cantilever beam is proportional to the cube of its length, the deformation of the two shorter cantilevers is less than that of the long cantilever, thereby improving the overall stiffness and deformation resistance of the hook mechanism in the long-stroke extension state, making the hook mechanism more deformation resistant and stable in operation.

[0024] Optionally, the system further includes a movable support assembly, which includes a support base positioned directly opposite the base plate along the length of the bottom rail. An extension base is provided on the lower side of the support base, and the extension base is slidably mounted on the base plate. A first controllable locking element is provided between the extension base and the base plate, used to lock the extension base and the base plate. The support base is located below the protruding plate, with its upper end slidably connected to the protruding plate. A second controllable locking element is provided between the front end of the protruding plate and the support base, used to lock the protruding plate and the support base.

[0025] By adopting the above technical solution, the movable support assembly, through the coordinated design of the support base, extension base, and first controllable locking component, allows the support base to move forward and be locked by the first controllable locking component. At this time, the support base provides stable mid-course support for the extension plate, effectively shortening the actual cantilever length of the extension plate and thus suppressing deflection and vibration of the extension plate under load. During the substrate reset process, the support base continues to support the extension plate, bringing it closer to the front end of the extension plate and reducing deformation. In this process, when the extension plate needs to reset, after the front end of the extension plate moves above the support base, the extension plate connects to the support base under the action of the second controllable locking component. At this time, the extension plate can drive the support base to reset synchronously, ensuring the smooth and reliable reset of the extension plate throughout the entire reset process.

[0026] Optionally, the extension base is arranged along the length direction of the bottom rail, the support base is slidably connected to the extension base along the length direction of the extension base, and a third controllable locking member is provided between the support base and the extension base, the third controllable locking member being used to lock the extension base and the support base.

[0027] By adopting the above technical solution, the sliding connection between the extension base and the support base, along with the cooperation of the third controllable locking component, allows the support base and the extension base to move relative to each other. Based on this design, through the coordinated action of the first, second, and third controllable locking components, the support base and the extension base can move synchronously and relative to each other during the operation of the substrate and the extension plate. Therefore, when the extension plate is at its maximum extension, the support base can be pushed closer to the front end of the extension plate, thereby further reducing the deformation generated when the extension plate is at its maximum extension. This further improves the ultimate load-bearing capacity and operational stability of the material-hooking mechanism.

[0028] Optionally, the second controllable locking component includes an electromagnet and a permanent magnet. The electromagnet is disposed on the upper side of the support base, and the permanent magnet is disposed on the lower side of the front end of the protruding plate. The electromagnet is used to magnetically fix the permanent magnet.

[0029] By adopting the above technical solution, the second controllable locking component, through the combined design of an electromagnet and a permanent magnet, ensures that when the front end of the extension plate moves above the support base, the electromagnet is energized, and the electromagnet and the permanent magnet attract each other, thus locking the support base and the extension plate. This locking method has the advantages of fast response speed, no mechanical wear, long service life, and convenient control, thereby meeting the usage requirements of the second controllable locking component.

[0030] In summary, this application includes at least one of the following beneficial technical effects: 1. This application, through the coordinated design of the bottom linear guide, bottom slide, top linear guide and top slide, can not only strengthen the rigidity of the hook plate, but also ensure the guiding nature of the hook plate. This reduces the deformation of the hook plate and improves the stability of the hook plate's movement, thereby ensuring the stability of the hooking mechanism's operation.

[0031] 2. Through the structural design of the hook assembly, this application enables the hook assembly to have flexibility and obstacle avoidance capabilities, thereby improving the adaptability and reliability of the hook assembly under complex working conditions.

[0032] 3. This application, through the design of double top rails and double bottom rails, forms a stable guide frame, which can resist the combined forces and torsional loads from the vertical and horizontal directions. This further enhances the anti-eccentric load capacity and overall operational stability of the hooking mechanism, thereby further improving the working stability of the hooking mechanism.

[0033] 4. Through the structural design of the hook plate, this application enables the hook mechanism to form a two-stage telescopic structure, thereby further enhancing the hook mechanism's resistance to deformation and its operational stability. Attached Figure Description

[0044] The following is in conjunction with the appendix Figure 1 - Appendix Figure 9 This application will be described in further detail below.

[0045] Example 1: A cantilevered bidirectional linear guide telescopic hooking mechanism, referring to... Figure 1 It includes a base plate 1, with hook plates 2 spaced apart above the base plate 1. Both the hook plates 2 and the base plate 1 are horizontally arranged, and a bidirectional guide assembly 4 is provided between the hook plates 2 and the base plate 1. A hook assembly 3 is provided at one end of the hook plate 2 along its length. A linear driver 5 is also provided on the base plate 1, and the driving end of the linear driver 5 is connected to the hook plates 2.

[0046] The design of the base plate 1, hook plate 2, hook assembly 3 and linear driver 5 allows the hook plate 2 to extend along its own length under the drive of the linear driver 5. Thus, the hook plate 2 can hook the carrier plate through the hook assembly 3 at its front end, which satisfies the basic function of the hook mechanism.

[0047] In this embodiment, refer to Figure 1 The linear actuator 5 is a linear module driven by a rodless cylinder, a pneumatic slide, or a servo motor.

[0048] Reference Figure 1 and Figure 2 The bidirectional guide assembly 4 includes a bottom rail 41, a bottom slide 42, a top rail 43, and a top slide 44. The bottom rail 41 and the top slide 44 are both fixed on the upper side of the base plate 1, and the top rail 43 and the bottom slide 42 are both fixed on the lower side of the hook plate 2. The bottom slide 42 is slidably mounted on the bottom rail 41, and the top slide 44 is slidably mounted on the top rail 43. The length directions of the base plate, the bottom rail 41, and the top rail 43 are all along the length direction of the hook plate 2.

[0049] With the design of the bidirectional guide assembly 4, the top rail 43 enhances the rigidity of the hook plate 2, thereby reducing the possibility of downward bending deformation at the front end of the hook plate 2. Simultaneously, the cooperation between the top rail 43 and the bottom rail 41 ensures the guiding performance of the hook plate 2. Therefore, this design reduces sagging, swaying, or jamming of the hook plate 2 due to cantilever loads, thus improving the stability of the hook plate 2 during movement and ensuring smooth operation of the hooking mechanism.

[0050] Reference Figure 2 The bottom slide 42 is located at the end of the hook plate 2 along the length of the hook plate 2, and the top slide 44 is located between the bottom slide 42 and the hook assembly 3 along the length of the hook plate 2.

[0051] The positioning of the bottom slide 42 and the top slide 44 increases the distance between the top slide 44 and the bottom slide 42, forming a longer lever arm. This allows for more effective resistance to the overturning moment generated by the hook assembly 3 and its load, thereby enhancing the rigidity and operational stability of the hook plate 2. In particular, when the hook plate 2 is fully extended, it can minimize the deflection deformation at the front end of the hook plate 2.

[0052] Reference Figure 1 and Figure 2 In this embodiment, two bottom linear guides 41 are provided, which are arranged in parallel and spaced apart. The linear actuator 5 is located between the two bottom linear guides 41, and the two bottom linear guides 41 are symmetrically arranged on both sides of the linear actuator 5. Two bottom slides 42 are provided, which are arranged one-to-one with the bottom linear guides 41, and the bottom slides 42 are slidably mounted on the corresponding bottom linear guides 41.

[0053] The symmetrical arrangement of the two bottom rails 41 improves the guiding properties and stability of the hook plate 2 during movement. Furthermore, the two bottom rails 41 effectively resist lateral forces or torsional loads that the hook plate 2 may experience during movement, preventing it from tilting or twisting. Compared to a single rail, the double-rail structure provides higher lateral stiffness and torsional resistance, ensuring the straightness and positioning accuracy of the hook mechanism during reciprocating motion.

[0054] Similarly, two top linear guides 43 are provided, arranged parallel and spaced apart. The linear actuator 5 is located between the two top linear guides 43, and the two top linear guides 43 are located between the two bottom linear guides 41. The two top linear guides 43 are symmetrically arranged on both sides of the linear actuator 5. Two top slides 44 are provided, each corresponding to one of the top linear guides 43, and the top slides 44 slide on the corresponding top linear guide 43.

[0055] Based on the design of the double top linear guide 43, on the one hand, the double top linear guide 43 and the double bottom linear guide 41 work together to form a stable guide frame, which can resist the combined forces and torsional loads from the vertical and horizontal directions. This further enhances the anti-eccentric load capacity and overall operational stability of the hooking mechanism, ensuring that the hook plate can maintain a precise movement trajectory even under harsh working conditions such as high speed or uneven load. On the other hand, the cooperative design of the double top linear guide 43 can further enhance the rigidity of the hook plate 2, thereby reducing the deformation of the hook plate and ensuring the stability of the hook plate's movement.

[0056] Reference Figure 3The material hook assembly 3 includes a vertical plate 31, which is vertically arranged and its lower end is rotatably connected to the front end of the material hook plate 2. A torsion spring 32 is provided between the vertical plate 31 and the material hook plate 2. One end of the torsion spring 32 is connected to the vertical plate 31 and the other end is connected to the material hook plate 2.

[0057] Based on the structural design of the hook assembly 3, the upright plate 31 remains vertical under the action of the torsion spring 32 to facilitate the hooking action. When the hook plate 2 hooks the carrier plate, after the upright plate 31 touches the carrier plate, the carrier plate abuts against the upright plate 31, causing the upright plate 31 to rotate against the elastic force of the torsion spring 32 until it is parallel to the hook plate 2. At this time, the upright plate 31 and the hook plate 2 can move under the carrier plate. When the upright plate 31 moves to the corresponding groove of the carrier plate, under the elastic force of the torsion spring 32, the upright plate 31 automatically rotates in the vertical direction, allowing the upright plate 31 to be inserted into the corresponding groove of the carrier plate, thereby realizing the hooking of the carrier plate. Therefore, the structural design of the hook assembly 3 gives it flexibility and obstacle avoidance capabilities, improving its adaptability and reliability under complex working conditions.

[0058] Reference Figure 3 and Figure 4 A limiting rod 35 is provided on the side of the upright plate 31 away from the hook plate 2, and the limiting rod 35 is connected to the hook plate 2. When the upright plate 31 is rotated to the vertical position, the side of the upright plate 31 away from the hook plate 2 abuts against the limiting rod 35.

[0059] Under the action of the limiting rod 35, the vertical plate 31 is precisely positioned in a vertical state under the elastic force of the torsion spring 32, thereby ensuring the reliability and repeatability of the material hooking action.

[0060] Reference Figure 3 and Figure 4 In this embodiment, the upright plate 31 is spaced apart from the front end of the hook plate 2 along its length. The upper end of the upright plate 31 extends beyond the upper surface of the hook plate 2. A mounting base 33 is provided at the lower end of the upright plate 31, and a limiting rod 35 is also provided on the mounting base 33. The mounting base 33 is located on the lower side of the hook plate 2, and the mounting base 33 is bolted to the lower side wall of the hook plate 2. A rotating shaft 34 is provided on the mounting base 33, and the length of the rotating shaft 34 is along the width of the hook plate 2. The lower end of the upright plate 31 is sleeved on the rotating shaft 34, and the upright plate 31 is rotatably connected to the rotating shaft 34. A torsion spring 32 is sleeved on the rotating shaft 34, and one end of the torsion spring 32 abuts against the upper side of the mounting base 33, and the other end abuts against the side of the upright plate 31 facing the hook plate 2.

[0061] Since the mounting base 33 is connected to the hook plate 2 by bolts, the mounting base 33 can be disassembled and replaced independently. Furthermore, since the upright plate 31, rotating shaft 34, torsion spring 32, and limiting rod 35 are all mounted on the mounting base 33, the entire hook assembly 3 and hook plate 2 are detachable, facilitating the replacement and maintenance of the hook assembly 3.

[0062] Reference Figure 3 The hook plate 2 has a clearance groove 21 at one end facing the vertical plate 31, and the clearance groove 21 extends vertically through the hook plate 2 and is positioned directly opposite the vertical plate 31 along the length of the hook plate 2. When the vertical plate 31 rotates to a horizontal position, the vertical plate 31 rotates into the clearance groove 21, and at this time, the upper side of the vertical plate 31 is flush with the upper side of the hook plate 2.

[0063] Based on the opening of the relief groove 21, after the hook plate 2 extends and the upright plate 31 touches the carrier plate, the upright plate 31 can rotate into the relief groove 21, so that there is no protrusion on the surface of the hook plate 2. This allows the hook plate 2 to pass under the corresponding carrier plate, thereby reducing the interference of the upright plate 31 on the movement of the hook plate 2.

[0064] The implementation principle of this embodiment is as follows: When performing the carrier plate hooking operation, firstly, the linear actuator 5 is activated, pushing the hooking plate 2 forward. When the upright plate 31 at the front end of the hooking plate 2 touches the target carrier plate, the upright plate 31 is pressed and rotates towards the hooking plate 2 until it rotates into the relief groove 21. At this time, the hooking plate 2 can move and insert under the carrier plate. When the upright plate 31 moves to the preset groove or hooking position of the carrier plate, under the action of the torsion spring 32, the upright plate 31 automatically rotates upward and springs up to a vertical state. At this time, the upright plate 31 enters the preset groove or hooking position of the carrier plate, thereby hooking the carrier plate. Finally, the linear actuator 5 moves in the opposite direction, resetting the hooking plate 2 together with the carrier plate, thereby completing one carrier plate hooking operation.

[0065] Example 2: A cantilevered bidirectional linear guide telescopic hooking mechanism, referring to... Figure 5 and Figure 6 The difference between this embodiment and Embodiment 1 is that: the hook plate 2 includes a base plate 22 and an extension plate 23. The base plate 22 is arranged parallel to the bottom plate 1 and is located above the bottom plate 1. The bidirectional guide assembly 4 is disposed between the base plate 22 and the bottom plate 1. The extension plate 23 is arranged parallel to the base plate 22 and is spaced above the base plate 22. The extension plate 23 is slidably connected to the base plate 22 along its own length direction, and the hook assembly 3 is located at one end of the extension plate 23 along its length direction. A secondary driver 24 is provided on the base plate 22, and the driving end of the secondary driver 24 is connected to the extension plate 23.

[0066] With the addition of the base plate 22, the extension plate 23, and the secondary actuator 24, the extension plate 23 and the base plate 22 can move relative to each other, allowing the hook plate 2 to extend or shorten independently. In this design, with the cooperation of the linear actuator 5 and the secondary actuator 24, the hook mechanism has a two-stage telescopic structure. To achieve the same total extension stroke, a single-stage telescopic structure requires a very long cantilever beam, while the two-stage telescopic structure consists of a relatively short base plate 22 and a relatively short extension plate 23. According to the principles of mechanics of materials, the deflection of a cantilever beam under load is proportional to the cube of its length. The two-stage telescopic structure decomposes the deformation problem of a long cantilever into the superposition of the deformation of the base plate 22 and the deformation of the extension plate 23. Since the lengths of the base plate 22 and the extension plate 23 are both less than the length of the cantilever beam in the single-stage telescopic structure, the deformation of each base plate 22 and the extension plate 23 is effectively controlled, and the total deformation after superposition is less than that of a single long cantilever beam under the same length and load. Therefore, the structural design of the hook plate 2 makes the hook mechanism exhibit stronger rigidity and resistance to deformation.

[0067] Reference Figure 5 and Figure 7 The top linear guide 43 and the bottom slide 42 are both located on the underside of the substrate 22, and the drive end of the linear driver 5 is also connected to the substrate 22.

[0068] Reference Figure 6 and Figure 7 A secondary guide assembly is provided between the substrate 22 and the protruding plate 23. The secondary guide assembly is similar in structure and principle to the bidirectional guide assembly 4.

[0069] Specifically, the secondary guide mechanism includes a first linear guide 25, a second linear guide 26, a first slide 27, and a second slide 28. The first linear guide 25 and the second slide 28 are both disposed on the upper side of the base plate 22. The first slide 27 is slidably disposed on the first linear guide 25, and the second slide 28 is slidably disposed on the second linear guide 26.

[0070] The structural design based on the secondary guide component ensures the stability of the relative movement between the substrate 22 and the protruding plate 23, and improves the structural rigidity of the protruding plate 23, reducing its deformation possibility, thereby ensuring the stability of the movement of the hook plate 2.

[0071] Reference Figure 5 The base plate 1 is also provided with a movable support component 6, which includes a support base 61 and an extension base 62 below the support base 61. The support base 61 is connected to the extension base 62, and the extension base 62 is slidably disposed on the base plate 1.

[0072] Reference Figure 5The support base 61 is positioned opposite the base plate 22 along the length of the base plate 1, and the extension base 62 is slidably connected to the base plate 1 along the length of the base plate 1. A first controllable locking member 63 is also provided between the extension base 62 and the base plate 1.

[0073] Reference Figure 5 and Figure 8 The upper end of the support base 61 is slidably disposed with the extension plate 23, and a second controllable locking element 64 is provided between the front end of the extension plate 23 and the support base 61.

[0074] Reference Figure 5 and Figure 9 Based on the design of the support base 61, during the process of hooking the carrier plate, firstly, the linear actuator 5 drives the substrate 22 to move, at which time the substrate 22 moves synchronously against the support base 61. When the substrate 22 moves into place, the first controllable locking member 63 locks the extension base 62 and the base plate 1 to ensure the stability of the support base 61. After that, the secondary actuator 24 drives the extension plate 23 to move, at which time the support base 61 and the extension plate 23 move relative to each other, and the support base 61 supports the extension plate 23. Finally, the extension plate 23 extends into place, realizing the hooking of the corresponding carrier plate. After hooking the carrier plate, firstly, the linear actuator 5 drives the substrate 22 to reset. Then, the secondary actuator 24 drives the extension plate 23 to reset. During this process, the support base 61 supports the extension plate 23 to reset, and when the front end of the extension plate 23 moves onto the support base 61, the second controllable locking member 64 locks the support base 61 and the extension plate 23, while the first controllable locking member 63 unlocks, at which time the support base 61 and the extension plate 23 reset synchronously.

[0075] Throughout this process, the support base 61 provides stable support and guidance for the reciprocating motion of the extension plate 23. Specifically, during the repositioning process of the carrier plate, after the base plate 22 is reset, the support base 61 supports the middle of the extension plate 23, thereby mitigating deformation of the extension plate 23 and ensuring its rigidity and guiding properties. Simultaneously, with the cooperation of the first controllable locking member 63 and the second controllable locking member 64, the support base 61 can transition from supporting the extension plate 23 to repositioning synchronously with it, thus ensuring the stability and repeatability of the carrier plate repositioning.

[0076] Reference Figure 5 and Figure 8 The extension base 62 is arranged along the length direction of the base plate 1, and the support base 61 is slidably connected to the extension base 62 along the length direction of the extension base 62, and a third controllable locking member 65 is provided between the extension base 62 and the support base 61.

[0077] With the design of the third controllable locking element 65, the support base 61 and the extension base 62 can be locked, which allows the support base 61 to slide on the extension base 62 and move synchronously with the extension base 62.

[0078] Based on this structural design, it has the following functions: Reference Figure 5 and Figure 9 Before the carrier plate is picked up, the support base 61 is located at the end of the extension base 62 away from the carrier plate, at which time the third controllable locking member 65 locks the support base 61 to the extension base.

[0079] During the process of picking up the carrier plate, the substrate 22 moves synchronously against the support base 61. After the substrate 22 is in place, the first controllable locking member 63 locks the extension base 62 to the base plate 1, thereby keeping the extension base 62 in a fixed position. At this time, the second controllable locking member 64 locks the support base 61 and the corresponding end of the extension plate 23, and the third controllable locking member 65 releases the lock between the support base 61 and the extension base 62. Then, the secondary driver 24 drives the extension plate 23 to move. At this time, the extension plate 23 moves synchronously with the support base 61, and the support base 61 moves synchronously with the extension base 62, until the support base 61 moves to the side of the extension base 62 close to the carrier plate. At this time, the second controllable locking member 64 releases the lock on the support base 61 and the extension plate 23, and the third controllable locking member 65 locks the support base 61 and the extension base 62 again.

[0080] This design allows the support base 61 to extend beyond the base plate 1, so that when the extension plate 23 is fully extended, the support base 61 can be closer to the middle of the extension plate 23. This makes the extension plate 23 more stable and reduces its deformation, thus ensuring better guidance when the extension plate 23 is reset.

[0081] Reference Figure 5 and Figure 9After the carrier plate is picked up, the secondary actuator 24 first drives the extension plate 23 to reset. During this process, the support base 61, which has been moved forward and locked, continues to support the retracting extension plate 23, preventing it from sagging or vibrating and ensuring its smooth retraction. When the front end of the extension plate 23 retracts to the support base 61, the second controllable locking member 64 locks the extension plate 23 to the support base 61, while the third controllable locking member 65 releases the lock between the support base 61 and the extension base 62. Then, the secondary actuator 24 continues to drive the extension plate 23 to retract, at which point the support base 61 and the extension plate 23 move synchronously. During this process, the support base 61 and the extension base 62 move relative to each other. When the support base 61 moves to the end of the extension base 62 near the substrate 22, the third controllable locking member 65 relocks the support base 61 to the extension base 62, and the first controllable locking member 63 releases the lock between the extension base 62 and the base plate 1. Afterwards, the secondary driver 24 continues to move, causing the extension plate 23, support base 61 and extension base 62 to move synchronously to the reset position.

[0082] With this structural design, the support point of the support base 61 on the protruding plate 23 can extend away from the substrate 22, so that after the protruding plate 23 is fully extended, the support base 61 can provide more stable support for the protruding plate 23, thereby suppressing the deflection deformation and vibration of the hook plate 2 during the hooking process of the carrier plate to the greatest extent. Therefore, this design not only enhances the rigidity and stability of the hooking mechanism under the limit stroke, but also enables the hooking mechanism to cope with hooking operations of longer distance and higher precision.

[0083] Reference Figure 7 and Figure 8 In this embodiment, a support slide 611 is provided on the upper end of the support base 61. The support slide 611 is provided in a one-to-one correspondence with the second linear rail 26, and the support slide 611 is slidably disposed on the second linear rail 26. Under the action of the support slide 611, the support base 61 can provide stable support for the protruding plate 23, and can also ensure stable sliding between the protruding plate 23 and the support base 61.

[0084] Reference Figure 5 and Figure 8 In this embodiment, the extension base 62 includes two extension plates 621. The length direction of the extension plates 621 is arranged along the length direction of the base plate 1. The two extension plates 621 are arranged in parallel and spaced apart, and the bottom rail 41 is located between the two extension plates 621. An auxiliary slide block 623 is provided on the lower side of the extension plate 621, and an auxiliary rail 622 is provided on the base plate 1. The auxiliary rail 622 is arranged in parallel and spaced apart from the bottom rail 41, and the auxiliary slide block 623 is slidably mounted on the corresponding auxiliary rail 622.

[0085] With the cooperation of auxiliary guide rail 622 and auxiliary slide block 623, a sliding connection between extension base 62 and base plate 1 is achieved.

[0086] Reference Figure 5 and Figure 8 The extension plate 621 is also provided with a guide rail, and the bottom of the support base 61 is provided with a guide slide. The guide rail and the guide slide are set one-to-one, and the guide slide is slidably set on the guide rail.

[0087] With the cooperation of the guide rail and the guide slide, a sliding connection is achieved between the support base 61 and the extension base 62.

[0088] Reference Figure 8 Limiting plates 624 are provided at both ends of the extension plate 621 along its length direction. The limiting plates 624 and the support base 61 are positioned opposite each other along the length direction of the corresponding extension plate 621.

[0089] The design of the extension base 62 enables a sliding connection between the extension base 62 and the base plate 1, as well as a sliding connection between the extension base 62 and the support base 61. Simultaneously, the design of the limiting plate 624 provides a clear mechanical limit on the sliding stroke of the support base 61 on the extension base 62, preventing the support base 61 from moving beyond the preset range and improving operational safety.

[0090] Reference Figure 8 and Figure 9 There are two first controllable locking elements 63, and each first controllable locking element 63 is set in a one-to-one correspondence with the extension plate 621, and the first controllable locking element 63 is set on the corresponding extension plate 621.

[0091] In this embodiment, the first controllable locking component 63 includes an electromagnetic push rod 631, which is mounted on the extension plate 621, and the axis of the electromagnetic push rod 631 is perpendicular to the base plate 1. The base plate 1 has a starting hole 632 and an ending hole 633, which are spaced apart along the length of the base plate 1. During the movement of the extension base 62 along the length of the base plate 1, the electromagnetic push rod 631 is sequentially positioned opposite the starting hole 632 and the ending hole 633.

[0092] When the extension base 62 is at the starting position on the base plate 1, the electromagnetic push rod 631 is aligned with the starting hole 632, and the driving end of the electromagnetic push rod 631 is coaxially inserted into the starting hole 632, locking the extension base 62 to the base plate 1. Similarly, when the extension base 62 moves to the ending position on the base plate 1, the electromagnetic push rod 631 is aligned with the ending hole 633, and the driving end of the electromagnetic push rod 631 is coaxially inserted into the ending hole 633, locking the extension base 62 to the base plate 1. During the movement of the extension base 62, the electromagnetic push rod 631 is de-energized, and the driving end of the electromagnetic push rod 631 retracts, thus ensuring the normal movement of the extension base 62.

[0093] Reference Figure 8 and Figure 9 In this embodiment, the first controllable locking member 63 and the third controllable locking member 65 have the same structure. Two third controllable locking members 65 are also provided, both mounted on the support base 61, and each third controllable locking member 65 corresponds to an extension plate 621. Specifically, the electromagnetic push rod 631 within the third controllable locking member 65 is mounted on the side wall of the support base 61, and the starting hole 632 and the ending hole 633 within the third controllable locking member 65 are both located on the corresponding extension plate 621.

[0094] This allows the third controllable locking member 65 to have the same function as the first controllable locking member 63, thereby enabling the positioning and locking of the support base 61 at both ends of the corresponding extension base 62 in the length direction, which satisfies the function of the third controllable locking member 65.

[0095] Reference Figure 7 and Figure 8 In this embodiment, the second controllable locking element 64 includes an electromagnet 641 and a permanent magnet 642. The permanent magnet 642 is disposed at the front end of the protruding plate 23 and is embedded in the lower side of the protruding plate 23. The electromagnet 641 is embedded in the upper side of the support base 61. When the support base 61 and the protruding plate 23 slide relative to each other until the permanent magnet 642 and the electromagnet 641 are directly opposite each other, the electromagnet 641 is energized, thereby magnetically attracting and fixing the electromagnet 641 and the permanent magnet 642. As a result, the protruding plate 23 can drive the support base 61 to move synchronously, and during this process, the support base 61 can synchronously support the front end of the protruding plate 23.

[0096] In this embodiment, the hooking mechanism also includes an intermediate controller, and the secondary driver 24, linear driver 5, electromagnetic push rod 631, and electromagnet 641 are all electrically connected to the intermediate controller. Under the control of the intermediate controller, the coordination of all actions of the hooking mechanism is ensured. Several position sensors are provided on the first linear rail 25, the second linear rail 26, the bottom linear rail 41, the top linear rail 43, the extension plate 23, the support base 61, the extension base 62, and the base plate 1. These position sensors are all electrically connected to the intermediate controller, which can acquire position feedback signals from each moving part. Based on these feedback signals, the intermediate controller can achieve closed-loop control of the entire hooking mechanism's movement process, ensuring that each action of the hooking mechanism is accurate. This effectively prevents component interference, collisions, or locking caused by position errors, thereby improving the automation level, positioning accuracy, and operational reliability of the entire hooking mechanism.

[0097] The implementation principle of this application embodiment is as follows: the hook plate 2, through the cooperation of the base plate 22 and the extension plate 23, enables the base plate 22 and the extension plate 23 to move synchronously and relative to each other, thereby transforming the single-stage telescopic structure into a two-stage telescopic structure. This decomposes the deformation problem of a long cantilever into the superposition of the deformations of two shorter cantilever arms, the base plate 22 and the extension plate 23. Based on the mechanical principle that the deflection of a cantilever beam is proportional to the cube of its length, this design structurally reduces the deformation of each stage of the telescopic arm, thereby improving the overall stiffness and deformation resistance.

[0098] Based on this, during the movement of the extension plate 23, the support seat 61 provides stable support for the extension plate 23, thereby reducing the deformation of the extension plate 23. This helps to suppress the sagging and vibration of the hooking mechanism under long stroke and high load conditions, ensuring high stability and high precision of the hooking operation.

[0099] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be included within the scope of protection of this application.
