Description

Technical Field

[0001] This invention relates to the field of detachable connection mechanism technology, and more specifically, to a quick docking structure for equipment unit modules. Background Technology

[0002] The content in this section only provides background information related to this invention and may not constitute prior art.

[0003] In the field of modern high-end equipment manufacturing, especially in precision fields such as semiconductor processing, production equipment is typically assembled from multiple unit modules with independent functions. During initial installation, routine maintenance, or process changes, it is often necessary to disassemble and replace specific unit modules.

[0004] Currently, the connection and fixation between unit modules generally adopts traditional mechanical connection methods, the most typical of which is to directly fasten two unit modules with bolts and other fasteners. Although this connection method is highly reliable and requires less skill from the operator, its disassembly and assembly operations are cumbersome and time-consuming, especially when the unit module structure is complex. Specifically, the traditional connection method requires sequentially aligning and tightening or removing a large number of bolts one by one. The entire process involves many steps and is time-consuming, which seriously affects the efficiency of unit module replacement. At the same time, when there are positioning constraints, the synchronous alignment of bolt holes is inconvenient, and it is difficult to quickly and easily ensure the consistency of the tightening state of all bolts, which restricts the convenience of equipment assembly and maintenance. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide a quick docking structure for equipment unit modules, which can realize quick and reliable connection and separation between unit modules, and greatly improve the efficiency of disassembly and assembly and the convenience of operation.

[0006] The objective of this invention is achieved through the following technical solution:

[0010] The unit base is used for fixed installation on the second unit module and is provided with a push-in groove; the reference base can be inserted into the push-in groove along the push-in direction and can move relative to the unit base in the push-in direction to a predetermined docking position;

[0011] A locking mechanism is provided on the unit base and is configured to be operable to switch between a locked state and an unlocked state;

[0012] When the reference base is in the predetermined docking position, the unit base and the reference base can be locked together by switching the locking mechanism from the unlocked state to the locked state; conversely, the locking mechanism can be released by switching the locking mechanism from the locked state to the unlocked state.

[0016] Specifically, when the locking hook is in the locked position, the locking hook engages with the locking hook mating part to put the locking mechanism in the locked state; when the locking hook is in the unlocked position, the locking hook disengages from the locking hook mating part to put the locking mechanism in the unlocked state.

[0017] Optionally, the locking hook engagement part is a locking rod disposed on the reference base; when the locking hook is in the locked position, the locking hook hooks and presses against the locking rod to achieve the engagement.

[0022] The operating lever is connected to the drive block and is used to drive the drive block to reciprocate within the slide rail.

[0023] The fixed block is provided with a force-applying part that cooperates with the force-receiving part; when the driving block is driven to move toward the inside of the slide, the force-applying part can interact with the force-receiving part to apply a driving force to the force-receiving part, forcing the locking hook to pivot toward the locking position.

[0024] Optionally, the reference base includes two reference blocks spaced apart in a lateral direction, the lateral direction being perpendicular to the pushing direction;

[0025] Each of the reference blocks has at least one guide limiting block on its outer side wall; the unit seat is provided with a limiting adjustment component corresponding to the guide limiting block;

[0026] The limiting adjustment component includes a limiting part, an adjusting part, and an elastic pre-tightening component; the limiting part is located in the pushing groove; the adjusting part is connected to the unit seat and is used to drive the limiting part to move along the lateral direction; the elastic pre-tightening component is used to provide a pre-tightening force to the limiting part so that it presses against the outer wall of the corresponding reference block;

[0027] When the reference seat is inserted into the push-in groove, the limiting part contacts the outer wall of the corresponding reference block; when the reference seat is in the predetermined docking position, the limiting part abuts against the corresponding guide limiting block.

[0028] Optionally, the outer side wall of each reference block is provided with multiple guide limiting blocks, and the multiple guide limiting blocks are arranged sequentially along the pushing direction;

[0029] The guide limiting block includes a first guide surface, a limiting surface, and a second guide surface connected sequentially along the pushing direction; the first guide surface and the second guide surface are inclined surfaces.

[0030] When the reference base is in the predetermined docking position, the limiting part abuts against the limiting surface of the corresponding guide limiting block.

[0031] Optionally, when the reference base is in the predetermined docking position, the locking mechanism is located between the two reference blocks.

[0032] Optionally, the reference base is provided with a plurality of second rolling elements arranged sequentially along the pushing direction;

[0033] When the reference seat is inserted into the push-in groove, the second rolling element makes rolling contact with the inner wall of the push-in groove.

[0034] Optionally, the reference base is provided with a positioning identification element for identifying whether the reference base has reached the predetermined docking position.

[0035] Optionally, the bottom of the unit base is provided with casters.

[0036] The technical solutions of the embodiments of the present invention have at least the following advantages and beneficial effects:

[0037] The quick-connection structure provided by this invention, by setting up a reference seat and a unit seat that cooperate with each other through a push-in groove, and with a locking mechanism that can switch between locked and unlocked states, greatly simplifies the connection and separation operations between two equipment unit modules. This structure fundamentally replaces the cumbersome steps of aligning and tightening bolts one by one in the traditional multi-bolt connection method, realizing an efficient disassembly and assembly process of "push-in for alignment, operation for locking", significantly improving the work efficiency of equipment unit module replacement and maintenance, and solving the core problem that the existing connection method restricts production efficiency due to numerous operation steps and long time consumption.

Detailed Implementation

[0049] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below in conjunction with specific embodiments. The same reference numerals in the accompanying drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the described embodiments of this invention without creative effort are within the scope of protection of this invention.

[0050] Compared to the embodiments shown in the accompanying drawings, feasible embodiments within the scope of protection of this invention may have fewer components, other components not shown in the drawings, different components, components with different arrangements, or components with different connections, etc. Furthermore, two or more components in the drawings may be implemented in a single component, or a single component shown in the drawings may be implemented as multiple separate components.

[0051] Unless otherwise defined, the technical or scientific terms used herein shall have the ordinary meaning as understood by one of ordinary skill in the art to which this invention pertains. The terms "first," "second," and similar terms used in this specification and claims do not indicate any order, quantity, or importance, but are merely used to distinguish different components.

[0052] Please refer to Figures 1 to 10 The embodiments of the present invention provide a quick docking structure for device unit modules, which is used to realize a detachable connection between a first unit module (not shown in the figure) and a second unit module (not shown in the figure), and in particular to realize quick and convenient assembly and disassembly between the two unit modules.

[0053] The unit modules described in this embodiment of the invention can be modules with independent functions that are already present in existing production equipment. For example, a unit module can be a cleaning chamber unit, a vacuum unit, a gas supply unit, etc., of a wafer cleaning machine.

[0054] Specifically, such as Figure 1 As shown, the quick docking structure includes a reference base 10, a unit base 20, and a locking mechanism 30.

[0055] The reference base 10 is used for fixed installation on the first unit module; the unit base 20 is used for fixed installation on the second unit module and is provided with a push-in groove 21, see Figure 3 and Figure 5 The reference base 10 can be inserted into the push-in slot 21 in the push-in direction and can move relative to the unit base 20 in the push-in direction to a predetermined docking position; the locking mechanism 30 is provided on the unit base 20 and is configured to be operable to switch between a locked state and an unlocked state.

[0056] When the reference base 10 is in the predetermined docking position, the unit base 20 and the reference base 10 can be locked together by switching the locking mechanism 30 from the unlocked state to the locked state; conversely, the locking mechanism 30 can be unlocked by switching it from the locked state to the unlocked state.

[0057] According to an embodiment of the present invention, when the reference base 10 and the unit base 20 are not docked, the reference base 10 is installed to the first unit module and remains fixed, while the unit base 20 is installed to the second unit module and is movable.

[0058] When assembling the first and second unit modules, first move the unit base 20 so that the reference base 10 aligns with the insertion slot 21. Then, operate the unit base 20 to move it, causing the reference base 10 to insert into the insertion slot 21 until the reference base 10 moves relative to the unit base 20 to the predetermined docking position. Finally, operate the locking mechanism 30, which is in the unlocked state, to switch it to the locked state, so that the unit base 20 and the reference base 10 are mutually locked, thereby fixing the first and second unit modules relatively. Afterward, only the corresponding functional components between the first and second unit modules need to be connected to complete the assembly. For example, when the first unit module is a cleaning chamber unit and the second unit module is a vacuum unit, simply connect the vacuum line of the vacuum unit to the vacuum port of the cleaning chamber unit.

[0059] Conversely, when it is necessary to separate the first unit module and the second unit module, first operate the locking mechanism 30, which is in the locked state, to switch it to the unlocked state, so as to release the lock between the unit seat 20 and the base seat 10. Then the unit seat 20 together with the second unit module can be moved away.

[0060] As can be seen, the quick docking structure provided in this embodiment of the invention, by setting a reference seat 10 and a unit seat 20 that cooperate with each other by means of a push-in groove 21, and cooperating with a locking mechanism 30 that can switch between locked and unlocked states, greatly simplifies the connection and separation operations between two equipment unit modules. This structure fundamentally replaces the cumbersome steps of aligning and tightening bolts one by one in the traditional multi-bolt connection method, realizing an efficient disassembly and assembly process of "push-in for alignment, operation for locking", significantly improving the work efficiency of equipment unit module replacement and maintenance, and solving the core problem that the existing connection method restricts production efficiency due to numerous operation steps and long time consumption.

[0061] In embodiments of the present invention, the pushing direction can be understood as the extending direction of the pushing groove 21, that is... Figure 1 The X-axis direction is shown in the diagram; the lateral direction, which will be described below, is perpendicular to the pushing direction, that is... Figure 1 The Y-axis direction is shown in the figure.

[0062] like Figure 3 and Figure 4 As shown, the reference base 10 may include two reference blocks 11 arranged at intervals in the lateral direction. Each reference block 11 extends in the pushing direction, forming an accommodating space between them.

[0063] The locking mechanism 30 may include a locking hook 31 and a drive assembly 32. The locking hook 31 is pivotally mounted on the unit base 20; the reference base 10 is provided with a locking hook mating part 12 that cooperates with the locking hook 31. When the reference base 10 is in a predetermined docking position, the locking hook 31 and the locking hook mating part 12 are aligned.

[0064] The drive assembly 32 is disposed on the unit base 20 and is operable to drive the locking hook 31 to pivot between a locked position and an unlocked position. (See reference...) Figure 7 As shown, when the locking hook 31 is in the locked position, the locking hook 31 engages with the locking hook mating part 12, so that the locking mechanism 30 is in a locked state, thereby realizing the locking between the reference base 10 and the unit base 20; Refer to Figure 6 As shown, when the locking hook 31 is in the unlocked position, the locking hook 31 disengages from the locking hook mating part 12, so that the locking mechanism 30 is in the unlocked state, thereby releasing the lock between the reference seat 10 and the unit seat 20.

[0065] By employing a locking mechanism 30 consisting of a pivotable locking hook 31 and a drive assembly 32, and providing a corresponding locking hook mating part 12 on the base 10, a simple and reliable locking method is provided. In practical applications, the operator only needs to operate the drive assembly 32 to achieve quick engagement and disengagement of the locking hook 31 and the locking hook mating part 12, making the operation simple and convenient.

[0066] In a preferred embodiment of the invention, the locking hook engagement part 12 may be a locking rod disposed on the reference base 10, particularly between the two reference blocks 11. This locking rod extends in the lateral direction. Referring again to Figure 6, when the locking hook 31 is in the unlocked position, the locking hook 31 is completely disengaged from the locking rod; correspondingly, referring again to… Figure 7 As shown, when the locking hook 31 is in the locked position, the locking hook 31 hooks and presses against the locking rod to achieve engagement between the locking hook 31 and the locking rod, thereby preventing the reference seat 10 from disengaging from the push-in groove 21 relative to the unit seat 20.

[0067] The locking hook mating part 12 of this structure is simple in structure. It can not only reliably prevent the locking hook 31 from separating from the locking hook mating part 12, but also press the locking rod with the locking hook 31 to generate continuous positive pressure on the contact surface, thereby effectively improving the overall structural rigidity and connection stability after docking, and ensuring the accuracy and reliability of docking.

[0068] In some possible embodiments, such as Figure 4 , Figure 6 and Figure 7 As shown, the drive assembly 32 may include a fixed block 321, an elastic element 322, a drive block 323, and an operating lever 324.

[0069] The fixing block 321 is fixedly disposed in the push-in groove 21, for example, at the inner top of the push-in groove 21. The fixing block 321 is provided with a slide 325 extending in the push-in direction. One end of the slide 325 passes through one side of the fixing block 321 to facilitate the subsequent hinged connection between the locking hook 31 and the drive block 323.

[0070] The elastic element 322 acts on the locking hook 31 to provide an elastic restoring force that tends the locking hook 31 toward the unlocked position. That is, the elastic element 322 can elastically hold the locking hook 31 in the unlocked position. For example, the elastic element 322 may be as follows: Figure 6 or Figure 7 The tension spring shown; one end of the tension spring is connected to the locking hook 31, and the other end is connected to the drive block 323.

[0071] The drive block 323 is slidably disposed on the slide rail 325, allowing it to slide along the slide rail 325. The locking hook 31 is hinged to the drive block 323 via the hinge shaft 326 and includes a force-receiving part 311.

[0072] The operating lever 324 is connected to the drive block 323 for driving the drive block 323 to reciprocate within the slide rail 325. Exemplarily, one end of the operating lever 324 can extend into the drive block 323 and be threadedly connected to it; the other end of the operating lever 324 extends away from the drive block 323 along the pushing direction and is provided with an operating part 327. The operating part 327 is used by the operator to drive the operating lever 324 to rotate. When the operating lever 324 rotates, based on the threaded transmission principle, the drive block 323 can convert the rotational motion of the operating lever 324 into linear motion, allowing it to slide within the slide rail 325.

[0073] Preferably, the push-in groove 21 can be a through groove extending through the unit seat 20 along the push-in direction. The length of the operating lever 324 satisfies the following condition: when the reference seat 10 is in the predetermined docking position, the operating part 327 is located as far away from the locking hook 31 as possible from the push-in groove 21. Figure 1 This allows the operator to easily drive the operating lever 324 to rotate via the operating unit 327 when the reference base 10 is inserted into the push-in slot 21 and is in the predetermined docking position.

[0074] Additionally, the fixing block 321, especially the fixing block 321 near the opening end of the slide 325, is provided with a force-applying part 328 that cooperates with the force-receiving part 311. This force-applying part 328 is configured such that when the driving block 323 is driven to move inward toward the slide 325, the force-applying part 328 can interact with the force-receiving part 311, specifically by pressing the force-receiving part 311 to apply a driving force to the force-receiving part 311, forcing the locking hook 31 to pivot toward the locking position. For example, the force-applying part 328 can be the inner wall of the slide 325.

[0075] With the above configuration, based on the threaded connection between the operating lever 324 and the drive block 323, when the operator rotates the operating lever 324, the drive block 323 moves inward toward the slide rail 325 along the pushing direction. This allows the force-applying part 328 to apply a driving force to the force-receiving part 311, forcing the locking hook 31 to move toward the locking position. This driving force is greater than the elastic restoring force applied to the locking hook 31 by the elastic member 322, allowing the locking hook 31 to move around the hinge axis 326 from... Figure 6 The unlock position shown is pivoted to Figure 7 The locking position is shown; conversely, when the operator rotates the operating lever 324 in the opposite direction, the drive block 323 can move outward along the pushing direction towards the outside of the slide 325, thereby allowing the force-applying part 328 to gradually remove the driving force applied to the force-receiving part 311, and the locking hook 31 will be released from the position under the action of the elastic restoring force provided by the elastic member 322. Figure 7 The locked position shown is reset to as follows: Figure 6 The unlock location is shown.

[0076] By employing the drive assembly 32 constructed as described above, a synergistic mechanism of "linear follow-up - fixed-point triggering - elastic reset" is constructed. This mechanism enables the operating lever 324 to drive the drive block 323 to move linearly inward during locking operations. The fixed force application part 328 precisely triggers the locking hook 31 to overcome the elastic reset force and reliably pivot to the locked position. The locking process is smooth, controllable, and the force is clear, effectively preventing the locking hook 31 from resetting in the locked position. During unlocking, only the operating lever 324 needs to be rotated in the opposite direction to move the drive block 323 outward. The locking hook 31 then automatically and quickly resets to the unlocked position under the reliable action of the elastic element 322. The entire mechanism achieves high rigidity maintenance of the locked state and rapid automatic reset of the unlocking action, greatly improving the convenience and reliability of operation.

[0077] In some possible embodiments, the drive component 32 may further include, for example, Figure 6 or Figure 7 The buffer elastic element 329 is shown. The buffer elastic element 329 can be a buffer straight spring and is parallel to the movement direction of the drive block 323. One end of the buffer elastic element 329 is connected to the drive block 323, and the other end is connected to the innermost side of the slide rail 325.

[0078] By setting the buffer elastic element 329, the moving drive block 323 can play a good buffering role, so that the drive block 323 can slide more stably along the slide 325, and help the drive block 323 to reset more quickly when the driving force needs to be removed.

[0079] In some possible embodiments, refer to Figure Figure 3 or Figure 4 As shown, when the reference base 10 includes the two reference blocks 11 mentioned above, the position of the locking mechanism 30 can be further reasonably set. Specifically, the locking mechanism 30 is set in the push-in groove 21 so that when the reference base 10 is in the predetermined docking position, the locking mechanism 30 is located between the two reference blocks 11.

[0080] This positioning makes full use of the structural space of the reference base 10, making the entire quick docking structure more compact in the docking state and reducing additional space occupation. At the same time, arranging the locking mechanism 30 between the two reference blocks 11 is conducive to the uniform distribution of force and avoids the additional torque that may be generated due to offset locking, thereby improving the stability and anti-eccentric load capacity of the overall structure after docking.

[0081] Furthermore, in practical implementation, multiple locking mechanisms 30 arranged sequentially in the lateral direction can be provided on the unit base 20. For example, the accompanying drawings of the present invention illustrate a case with two locking mechanisms 30. Of course, the number of locking mechanisms 30 is not limited to this, and no further limitation is made here. By providing more locking mechanisms 30, it is beneficial to further improve the reliability of the docking and locking of the reference base 10 and the unit base 20.

[0082] In some possible embodiments, refer to Figure 3 and Figure 4 As shown, each reference block 11 has at least one guide limiting block 40 on its outer side wall. The unit seat 20 is provided with a limiting adjustment member 50 corresponding to the guide limiting block 40. The outer side wall of each reference block 11 refers to the outer side wall of the two reference blocks 11 that is opposite to each other in the lateral direction. The limiting adjustment member 50 is used to cooperate with the guide limiting block 40 to reliably limit the degree of freedom of the unit seat 20 in the lateral direction.

[0083] Specifically, refer to Figure 8 and Figure 9 As shown, the limiting adjustment member 50 includes a limiting part 51, an adjusting part 52, and an elastic preload member 53 arranged sequentially in the lateral direction. The limiting part 51 is located within the push-in groove 21. The adjusting part 52 is connected to the unit seat 20 and is used to drive the limiting part 51 to move in the lateral direction to adjust the lateral position of the limiting part 51. Exemplarily, the adjusting part 52 may be a screw threadedly connected to the unit seat 20, with one end of the screw away from the limiting part 51 exposed on the outer side wall of the unit seat 20, so that the operator can rotate it to drive the limiting part 51 to move in the lateral direction.

[0084] An elastic preload member 53 is disposed between the limiting portion 51 and the adjusting portion 52, and is used to provide a preload force to the limiting portion 51 to press it against the outer wall of the corresponding reference block 11. That is, the elastic preload member 53 can bias the limiting portion 51 toward the outer wall of the corresponding reference block 11. For example, the elastic preload member 53 may be an elastic adjusting ring.

[0085] Based on the above configuration, before fixing the reference base 10 and the unit base 20, the lateral position of the limiting part 51 can be adjusted as needed to avoid interference between the reference base 10 and the limiting part 51 after the reference base 10 is inserted into the push-in groove 21. When the reference base 10 is inserted into the push-in groove 21, the limiting part 51 contacts the outer wall of the corresponding reference block 11. On this basis, the limiting adjustment members 50 on both sides of the unit base 20 in the lateral direction can guide the movement of the unit base 20 so that the reference base 10 can be accurately inserted into the push-in groove 21. Furthermore, when the reference base 10 is in the predetermined docking position, the limiting part 51 of each limiting adjustment member 50 just reaches the position of the guide limiting block 40 on the corresponding reference block 11, and the limiting part 51 of each limiting adjustment member 50 abuts against the corresponding guide limiting block 40.

[0086] By setting guide limit blocks 40 on the outer side walls of each reference block 11 and setting limit adjustment parts 50 that cooperate with guide limit blocks 40 on the unit seat 20, an active lateral positioning and constraint system is formed. This system can not only guide the unit seat 20 through the contact surface during the pushing process, but also achieve precise lateral positioning when the reference seat 10 reaches the predetermined docking position through the abutment of the limit part 51 and the guide limit block 40, and use elastic pre-tightening force to eliminate gaps, thereby achieving high-precision repeatable positioning before locking, laying a solid foundation for final reliable locking.

[0087] Furthermore, multiple guide limiting blocks 40 are provided on the outer side wall of each reference block 11, and the multiple guide limiting blocks 40 are arranged sequentially along the pushing direction. For example, the accompanying drawings of the present invention show the case where each reference block 11 is provided with two guide limiting blocks 40.

[0088] Furthermore, referring to Figure 10 As shown, viewed from above, the guide limiting block 40 is trapezoidal in shape and includes a first guide surface 41, a limiting surface 42, and a second guide surface 43 connected sequentially along the pushing direction. The first guide surface 41 and the second guide surface 43 are inclined surfaces. When the reference seat 10 is in the predetermined docking position, the limiting part 51 abuts against the limiting surface 42 of the corresponding guide limiting block 40.

[0089] By constructing the guide limit block 40 with a specific shape featuring an inclined surface and arranging multiple blocks along the pushing direction, the limiting part 51 can smoothly transition along the inclined surface during the pushing process, and precisely abut against the vertical limiting surface 42 on the corresponding guide limit block 40 when reaching the final position. This design achieves the dual functions of "low-resistance guidance during pushing" and "precise locking after reaching the position," ensuring smooth pushing action while utilizing the cooperation between the inclined surface and the limiting surface 42 to achieve self-centering and gapless positioning, further improving positioning accuracy and operational feel.

[0090] In some possible embodiments, reference continues to be made to Figure 8 or Figure 9 The limiting part 51 may be provided with a first rolling element 54 for contacting the outer wall of the corresponding reference block 11. The first rolling element 54 may be a freely rolling ball that makes rolling contact with the outer wall of the corresponding reference block 11.

[0091] By setting the first rolling element 54, the friction between the limiting part 51 and the outer wall of the corresponding reference block 11, and between the limiting part 51 and the corresponding guide limiting block 40, is reduced, which greatly reduces the operating force required to push the unit seat 20 toward the reference seat 10, making the pushing operation more effortless and smooth.

[0092] In some possible embodiments, refer to Figure 3 and Figure 4 As shown, the reference base 10 is provided with a plurality of second rolling elements 60 arranged sequentially along the pushing direction. Preferably, the plurality of second rolling elements 60 can be provided on the top surface of the reference base 10, especially on the top surface of each reference block 11. The second rolling elements 60 can be freely rolling balls.

[0093] When the reference seat 10 is inserted into the push-in groove 21, the second rolling element 60 rolls into contact with the inner wall (specifically the inner top wall) of the push-in groove 21.

[0094] By setting a second rolling element 60 on the reference seat 10, which forms rolling contact with the inner wall of the push-in groove 21, sliding friction is successfully converted into rolling friction. This further reduces the operating force required to push the unit seat 20 toward the reference seat 10, making the push-in operation more effortless and smooth. This not only reduces the labor intensity of the operator, but also reduces the wear that may occur on the precision guide surface, which is conducive to maintaining positioning accuracy over a long period of time.

[0095] In some possible embodiments, the reference base 10 is provided with a positioning identification element 70 for identifying whether the reference base 10 has reached the predetermined docking position. For example, the positioning identification element 70 may be a physical positioning structure such as a positioning pin or a positioning block provided on the reference base 10. When the unit base 20 is pushed toward the reference base 10 so that the reference base 10 is inserted into the push-in groove 21 and the reference base 10 reaches the predetermined docking position, the unit base 20 can abut against the positioning identification element 70, thereby realizing the identification of whether the reference base 10 has reached the predetermined docking position.

[0096] This design provides a clear and reliable signal indication for determining whether the reference base 10 has accurately reached the predetermined docking position, eliminating the uncertainty of relying on visual observation or experience judgment during the docking process. This allows the operator to quickly and accurately confirm whether the docking is in place, thereby avoiding locking failure or equipment damage caused by inaccurate positioning and improving the safety and success rate of operation.

[0097] In some possible embodiments, casters (not shown in the figure) can be provided at the bottom of the unit base 20, so that the unit base 20 integrating the second unit module can be easily moved within the work site, greatly facilitating the transfer and initial alignment of the unit module.

[0098] The movable wheels on the unit base 20 are designed such that when the reference base 10 is inserted into the push-in groove 21, the movable wheels on the unit base 20 disengage from the ground. This design prevents the unit base 20 and the reference base 10 from easily shifting after they are docked and locked together.

[0099] In some possible embodiments, refer to Figure 4 As shown, the bottom of the reference base 10, especially the bottom of each reference block 11, is provided with feet 13. The feet 13 facilitate the convenient adjustment of the height of the reference base 10, thereby adapting to different assembly requirements.

[0100] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
