Description

Technical Field

[0001] This application relates to the field of transport rack assembly and manufacturing technology, and in particular to a telescopic rack for new energy battery packs and its assembly and testing platform. Background Technology

[0002] With the rapid development of the new energy industry, battery packs, as core energy units, face increasingly stringent efficiency and quality requirements in their manufacturing, assembly, and logistics. In battery pack production processes, racks serve as crucial tooling for support, positioning, and transportation, and due to their flexible structure and adaptability, they are widely used in the pre-assembly and transfer of battery pack components. In actual manufacturing, to ensure high-precision connections and rapid assembly between rack components, specialized assembly platforms are typically used for assisted positioning, thereby improving overall operational efficiency and finished product consistency.

[0003] Currently, widely used material racks typically use standardized metal profiles as their main component materials, such as rectangular steel pipes. These profiles are connected by mechanical methods such as screwing, welding, snap-fitting, and plugging to form an integral structure. To achieve efficient assembly, manufacturers often pre-process the main components of the material rack into preliminary shapes and then use an assembly platform to complete the final assembly. During the assembly process, each component is usually positioned and connected on a workbench or dedicated assembly platform. Appropriate tooling fixtures are used to achieve accurate docking between components, and welding or fasteners are used for fixation. To ensure the consistency of components, pre-installed interfaces for connection are provided on the components, facilitating direct combination with connectors or other components to achieve modular splicing and rapid positioning.

[0004] However, the pre-designed interfaces on the components using the profiles themselves are mostly pre-formed structures. During the storage, handling, transportation, and stacking of the components, due to uncontrollable factors such as external impacts, collisions, and compression, the reserved interface positions at the ends of the profiles are prone to deformation. Especially when no calibration auxiliary devices are used in the early stages of assembly, it is easier for the components to fail to assemble smoothly, leading to problems such as connection difficulties, interface misalignment, and installation deviations during the assembly process. This seriously affects the assembly accuracy and efficiency, and consequently affects the structural stability of the entire rack. Furthermore, once assembly errors occur between components, rework or manual adjustment is often required, further increasing manufacturing costs and time. Summary of the Invention

[0005] This application provides a telescopic rack for new energy battery packs and its assembly and testing platform. The telescopic rack has a standardized rectangular frame structure with modular and telescopic characteristics, which effectively improves the compatibility of the structure and the overall adaptability of the product. At the same time, the assembly and testing platform can realize an integrated process of "inspection-judgment-repair-assembly", which significantly improves the consistency and efficiency of assembly quality.

[0006] Firstly, the telescopic rack for a new energy battery pack provided in this application adopts the following technical solution:

[0007] A telescopic rack for new energy battery packs, comprising:

[0008] A central connecting frame is located at the center of the telescopic material rack, and a first insertion part is fixed on each of the four side walls of the central connecting frame;

[0009] Four sets of corner support frames are located around the central connecting frame. Two sets of corner support frames are provided on each side of the central connecting frame along its length. The two sets of corner support frames on the same side are symmetrically arranged along the width of the central connecting frame. Each set of corner support frames has a first connection port on its adjacent side.

[0010] Two sets of long-side connecting frames are provided, each set of long-side connecting frames being located between the two sets of corner support frames along the length direction of the central connecting frame, and symmetrically arranged along the width direction of the central connecting frame; each of the two sides of the long-side connecting frame facing the corner support frame is provided with a second insertion part, the second insertion part being slidably inserted into the first connection port; a second connection port is provided on the side of the long-side connecting frame facing the central connecting frame, the second connection port being slidably inserted into the first insertion part;

[0011] Two sets of wide-side connecting frames are provided, each set of wide-side connecting frames being located between two sets of corner support frames in the width direction of the central connecting frame, and symmetrically arranged along the width direction of the central connecting frame; each wide-side connecting frame has a third insertion part on its two sides facing the corner support frames, the third insertion part being slidably inserted into the first connection port; a third connection port is provided on the side of the wide-side connecting frame facing the central connecting frame, the third connection port being slidably inserted into the first insertion part;

[0012] The central connecting frame, the corner support frame, the long side connecting frame, and the wide side connecting frame are connected to each other to form a rectangular frame structure, thereby constituting the main body of the telescopic material rack;

[0013] The first connection port, the second connection port, and the third connection port all have the same feature settings, and the first plug-in portion, the second plug-in portion, and the third plug-in portion all have the same feature settings.

[0014] By adopting the above technical solution, and using the central connecting frame as the core structural unit, combined with four sets of corner support frames, two sets of long-side connecting frames, and two sets of wide-side connecting frames, a standardized rectangular frame structure with modular and scalable characteristics is constructed. All components are connected by sliding plug-in and bolt fastening, eliminating the need for complex fastening structures. This facilitates rapid on-site assembly or disassembly and adjustment, significantly improving assembly efficiency and adapting to diverse assembly scenarios and varying battery pack sizes. Furthermore, the unified interface standard and strong component versatility not only simplify component processing but also facilitate interchangeability between components, improving structural compatibility and overall product adaptability.

[0015] Secondly, this application provides an assembly and testing platform for a telescopic rack for new energy battery packs, employing the following technical solution:

[0016] A telescopic rack for new energy battery packs, characterized in that:

[0017] A machine base, wherein a controller is installed on the machine base;

[0018] An assembly mechanism includes a first sliding plate, a second sliding plate, and a third sliding plate. Two sets of the first and second sliding plates are provided, with the two sets of first sliding plates symmetrically sliding on both sides of the machine tool's width direction. Two sets of second sliding plates are also symmetrically sliding on both sides of the machine tool's width direction. Multiple sets of the third sliding plate are provided, with two sets of the third sliding plates symmetrically arranged on each set of first sliding plates. The upper surface of the second sliding plate is flush with the upper surface of the third sliding plate.

[0019] The testing mechanism includes a displacement component, an interface detection component, and an interface repair component. The displacement component is mounted on the machine platform, and a detection arm is vertically mounted on the displacement component. The interface repair component is located at one end of the detection arm, and the interface detection component is located on the third sliding plate. Both the interface detection component and the interface repair component are movably corresponding to the first connection port. Both the interface detection component and the interface repair component can act on the first connection port. The interface detection component can detect whether the first connection port is deformed, and the interface repair component can repair the deformed first connection port.

[0020] By adopting the above technical solution, the assembly platform is equipped with multiple sets of first sliding plates, second sliding plates, and third sliding plates. The three work together and can be flexibly adjusted according to the position of the components of the telescopic rack to be assembled, so as to achieve precise positioning of rack components of different sizes and specifications on the platform. In addition, the multi-sliding plate structure provides adjustable freedom in the width and depth directions, which significantly improves the versatility and flexibility of the assembly platform, reduces the dependence on manual positioning, and improves the efficiency and accuracy of assembly operations.

[0021] The assembly and inspection platform integrates an inspection mechanism and interface repair components. It can automatically inspect and judge key connection points of the material rack components (such as the first connection point) before assembly, identifying whether the interface is deformed or misaligned. If an abnormality is detected, the interface repair component can automatically correct or reshape it, achieving pre-processing of interface accuracy before assembly. This avoids connection difficulties, misalignment, or excessive assembly tolerances caused by interface deformation. This enables an integrated "inspection-judgment-repair-assembly" process, significantly improving assembly quality consistency and efficiency. Compared to existing technologies that lack verification methods for material rack interfaces, are prone to misalignment in the early stages of assembly, and have undetectable errors, this platform effectively solves the technical pain points of "difficulty in predicting interface deformation" and "high rework costs after assembly errors occur." It ensures that each connection point has a good assembly fit before assembly, guaranteeing assembly accuracy from the source. Simultaneously, it avoids traditional, labor-intensive methods such as extensive rework and manual adjustments, reducing labor costs and improving process standardization.

[0022] Optionally, the interface detection component includes a deflection drive, a deflection plate, and a first detection component. A detection seat and a mounting seat are fixedly provided on the third sliding plate. The mounting seat is disposed on one side of the detection seat and has a placement groove. The first connection port overlaps in the placement groove. The deflection drive is disposed on the mounting seat. The output end of the deflection drive is fixedly connected to one end of the deflection plate. The first detection component is disposed on the deflection plate.

[0023] The first detection component includes a first pressing drive, a first abutting plate, and a first piston tube. The first abutting drive is fixedly mounted on the deflection plate. Both the deflection drive and the first abutting drive are electrically connected to the controller. The first abutting plate is fixedly connected to the output end of the first abutting drive. The first abutting drive can drive the first abutting plate to press against the outer wall of the first connection port. The first piston tube is fixedly mounted on the first abutting plate. A piston block is slidably disposed inside the first piston tube. The piston block divides the first piston tube into two chambers, which are respectively designated as the first chamber and the second chamber. An abutting rod is fixedly mounted at one end of the piston block. The end of the abutting rod away from the piston block extends out of the piston tube and slidably passes through the first abutting plate. The end of the abutting rod away from the piston block is configured as a hemispherical surface.

[0024] The first piston tube on the first abutment plate is provided with multiple sets, and the multiple sets of first piston tubes are arranged linearly along the length direction of the first abutment plate. A connecting pipe is provided at the end of the first piston tube away from the first abutment plate, and the second chambers on the multiple sets of first piston tubes are interconnected through the connecting pipe.

[0025] By adopting the above technical solution, the deflection drive component drives the deflection plate to deflect, which makes it easier for the first connection port on the component to be tested (such as the corner support frame) to overlap in the placement slot during the initial stage of assembly. This enables the component to be placed quickly and stably, reduces manual intervention, and improves the overall assembly efficiency. The first detection component adopts a hydraulic piston structure to convert the slight deformation of the outer wall of the connection port into pressure changes in the cavity. Through piston sliding and internal hydraulic oil flow, the actual state of the connection port is reflected. It has good sensitivity and repeatability and is suitable for detecting micro-deformation caused by transportation or stacking. Furthermore, the multiple sets of first piston cylinder structures arranged linearly along the abutment plate can simultaneously perform more comprehensive contact detection on one side, achieving integrated and rapid judgment and ensuring comprehensive and consistent test results.

[0026] Optionally, the interface detection component further includes a display tube, which is fixedly mounted on the first abutment plate. A sliding block is slidably disposed inside the display tube, which divides the display tube into two chambers, which are respectively designated as a third chamber and a fourth chamber. The third chamber is connected to the second chamber, and both the second and third chambers are filled with hydraulic oil. A distance sensor is disposed at the end of the display tube away from the third chamber, and the distance sensor is electrically connected to the controller.

[0027] By adopting the above technical solution, and introducing a hydraulic display mechanism consisting of a sliding block and a display tube into the interface inspection component, accurate measurement of the interface sidewall deformation is achieved. Since the third chamber and the second chamber are connected by hydraulic oil, and multiple sets of first piston tubes are interconnected through connecting pipes, the hydraulic changes caused by the piston action during interface inspection can directly drive the sliding block to move in the display tube, thereby converting the degree of interface deformation into quantifiable displacement information. The distance sensor set at the end of the display tube detects the position of the sliding block in real time and feeds the data back to the controller, enabling digital acquisition and dynamic monitoring of interface deformation. This helps to build a closed-loop control system for interface assembly quality. Compared with the traditional method of judging interface deformation by manual observation or mechanical contact, this structure has the advantages of simple structure, high precision, and fast response. It can significantly improve the reliability, efficiency, and automation level of interface inspection, effectively reduce rework rate, and ensure the assembly quality of the material rack.

[0028] Optionally, the interface detection component further includes a second detection component, the second detection component having the same feature settings as the first detection component. The third detection component is provided in three sets within the placement slot. The second detection component includes a second abutting drive component and a second abutting plate. The second abutting drive component is fixed on the detection seat. An avoidance groove is provided on the inner wall of the placement slot. The second abutting plate is located within the avoidance groove. The second abutting plate and the first abutting plate together form a repair frame for limiting the repair of the connection port. The repair frame is fitted onto the first connection port.

[0029] By adopting the above technical solution, the second abutment plate is set in the clearance groove on the inner wall of the detection seat, avoiding direct collision or interference with it during the placement of assembly components or movement of the interface, effectively reducing the risk of false triggering of the detection component or misjudgment of the connection state, and improving the overall stability and reliability of the detection platform. As an independent detection unit, the second detection component and the first detection component form a complementary distribution, which can perform spatial three-dimensional detection of the deformation of the first connection from multiple directions, avoiding blind spots on one side, improving detection coverage and accuracy, and providing reliable data support for subsequent automatic repair. The second detection component and the first detection component maintain consistent design features, which is convenient for mass manufacturing and unified management. In addition, the repair frame formed by the cooperation of the second abutment plate and the first abutment plate not only provides stable support for the connection, but also effectively prevents interface displacement, shaking or deviation during assembly, ensuring that the repair tool acts on the correct area, and provides an accurate repair window for subsequent interface repair operations, ensuring that the repair process is completed strictly within the control range, and avoiding deformation expansion or structural damage caused by repair path deviation or overloading.

[0030] Optionally, the interface repair component includes a first motor and a repair roller. The end of the detection arm near the machine base is rotatably equipped with a mounting plate. The first motor is fixed on the mounting plate. The repair roller is shaped like a frustum cone, and its cross-section is a Reuleaux triangle. A connecting shaft is fixed on the large-diameter end of the repair roller. The connecting shaft is eccentrically positioned with the repair roller and is fixedly connected to the output end of the first motor. The repair roller can repair the concave deformation at the first connection port.

[0031] By adopting the above technical solution, the interface repair component includes a frustum-shaped repair roller with an eccentric connecting shaft and a first motor. The cross-section of the frustum-shaped repair roller adopts a Reuleaux triangle shape, which can adapt to interface parts with different diameters and degrees of deformation, achieving a precise repair function, avoiding jamming and gaps during assembly, and reducing rework rate and scrap rate. At the same time, through online automatic detection and repair, the reliance on external repair processes and manual adjustments is reduced, saving manpower, time and material costs, and improving enterprise production efficiency.

[0032] Optionally, the testing mechanism further includes a trial assembly component, which includes a clamping drive and a punch plug. The clamping drive is electrically connected to the controller and is fixed on the side of the mounting plate opposite to the repair roller. The clamping drive can clamp the punch plug and install it onto the first insertion part. One end of the punch plug is provided with a connecting part, which is adapted to the inner cavity shape of the first insertion part. The other end of the punch plug is provided with a friction ring, which is provided with file teeth and is adapted to the shape of the first connection port.

[0033] By adopting the above technical solution, the trial assembly component automatically clamps the punch plug through the clamping drive component. The clamping drive component can quickly install the punch plug on the first insertion part, and can perform minor repairs and cleaning on the inner wall of the interface during the trial assembly process, effectively eliminating slight burrs or deformations of the interface, improving the insertion fit, and reducing the risk of assembly jamming caused by interface deformation.

[0034] Optionally, the trial assembly further includes a locking component, which includes a locking plate and a retaining spring. The punch plug has a receiving groove, the locking plate is slidably disposed in the receiving groove, and one end of the locking plate extends out of the punch plug. The other end of the locking plate is fixed with a locking pin, which slidably passes through the punch plug and engages with a pre-set bolt mounting hole on the first insertion part. Two sets of locking plates are provided, and the two sets of locking plates are symmetrically arranged along the width direction of the punch plug. The retaining spring is disposed between the two sets of locking plates. The clamping drive can act on the ends of the two sets of locking plates that extend out of the punch plug, thereby bringing the two sets of locking plates closer to each other and causing the locking pin to retract into the receiving groove.

[0035] By adopting the above technical solution, the locking plate and locking pin work together to firmly fix the punch plug in the preset position, preventing the punch plug from loosening or shifting during the trial assembly process, and ensuring the accuracy and repeatability of the trial assembly test.

[0036] Optionally, the third sliding plate is further provided with an automatic straightening component, which includes an extension seat, a translation drive, a second motor, and a straightening roller. The extension seat is slidably disposed on the third sliding plate and is located on one side of the detection seat. A straightening groove is formed through the extension seat. The translation drive is fixedly disposed on the third sliding plate and is electrically connected to the controller. The output end of the translation drive is fixedly connected to the extension seat. The translation drive can drive the extension seat to reciprocate along its width direction on the third sliding plate. Sliding; a rotating seat is fixed on the extension seat, the straightening roller is rotatably mounted on the rotating seat, the straightening roller is supported on the straightening groove through the rotating seat, the second motor is fixed on the rotating seat, the second motor is electrically connected to the controller, the output end of the second motor is fixedly connected to one end of the straightening roller, the straightening roller is provided in four groups, of which two groups of the straightening roller are combined to form a horizontal straightening group, and the other two groups of the straightening roller are combined to form a vertical straightening group. The horizontal straightening group and the vertical straightening group are arranged perpendicularly and intersectingly, and the horizontal straightening group is located on one side of the vertical straightening group.

[0037] By adopting the above technical solution, the automatic straightening component, through the cross arrangement of horizontal and vertical straightening groups, achieves forced straightening of the first insertion part in multiple directions. This effectively eliminates deformation of the insertion part caused by storage and transportation, ensures the accuracy of the size and shape of the insertion part, avoids assembly difficulties and jamming problems caused by interface deformation during assembly, and significantly improves assembly efficiency and quality stability. At the same time, the automatic straightening component adopts motor drive and intelligent control to achieve automated straightening without manual intervention, reducing assembly rework and maintenance costs, and improving the automation level of the production line and manufacturing economic benefits.

[0038] In summary, this application includes at least one of the following beneficial technical effects:

[0039] 1. The assembly and inspection platform integrates an inspection mechanism and interface repair parts. It can automatically inspect and judge the key connection ports (such as the first connection port) of the material frame components before assembly, identify whether there is deformation or misalignment of the interface, and when abnormalities are detected in the interface, the interface repair parts can automatically correct or reshape and repair, realizing an integrated process of "inspection-judgment-repair-assembly". This significantly improves the consistency and efficiency of assembly quality, effectively solves the technical pain points of "difficulty in predicting interface deformation" and "high rework cost after assembly error occurs", ensures that each connection port has a good assembly fit state before assembly, guarantees assembly accuracy from the source, and avoids traditional extensive methods such as a large amount of rework and manual hammering and adjustment, reducing labor costs and improving the level of process standardization.

[0040] 2. The first detection component uses a hydraulic piston structure to convert slight deformation of the outer wall of the connection port into pressure changes within the cavity. Combined with a hydraulic display mechanism consisting of a display tube, the hydraulic changes generated by the piston action can directly drive the sliding block to move within the display tube. A distance sensor is installed to detect the position of the sliding block in real time, enabling digital acquisition and dynamic monitoring of interface deformation. This helps to build a closed-loop control system for interface assembly quality. Compared with traditional methods that rely on manual observation or mechanical contact to judge interface deformation, this structure has the advantages of simple structure, high precision, and fast response. It can significantly improve the reliability, efficiency, and automation level of interface detection, effectively reduce rework rate, and ensure the assembly quality of the material rack.

[0041] 3. The repair frame formed by the cooperation of the second abutment plate and the first abutment plate not only provides stable support for the connection, but also effectively prevents the interface from shifting, shaking or deviating during the assembly process, ensuring that the repair tool is applied to the correct area. Furthermore, it provides an accurate repair window for subsequent interface repair operations, ensuring that the repair process is completed strictly within the control range, and avoiding deformation expansion or structural damage caused by repair path deviation or overloading.

[0080] The trial assembly component 44 includes a clamping drive component 441, a punch plug 442, and a locking component 443. The clamping drive component 441 can be configured as an electric gripper. The clamping drive component 441 is electrically connected to the controller 21 and is fixed on the mounting plate 412. The punch plug 442 is configured as a rectangular block. One end of the punch plug 442 is provided with a connecting part 4421, which is adapted to the inner cavity shape of the first insertion part 111.

In the initial state, the output end of the clamping drive 441 clamps one end of the two sets of locking plates 4431 that protrudes from the punch plug 442, thereby bringing the two sets of locking plates 4431 closer to each other and causing the locking pin 4433 to retract into the receiving groove.

[0082] In this embodiment, a placement platform is provided on one side of the assembly and testing platform. Multiple sets of placement plates are fixed on the placement platform, and multiple sets of square slots are evenly spaced along its length. The size of the square slots matches the shape of the connecting part 4421. Multiple sets of punch plugs 442 are placed on the placement platform through the square slots, thereby facilitating minor trimming and cleaning of the inner wall of the interface during the assembly process. This effectively eliminates minor burrs or deformations of the interface, improves the fit, and reduces the risk of assembly jamming caused by interface deformation. The placement platform is not shown in the accompanying drawings of this embodiment.

[0083] The implementation principle of the assembly and testing platform for the telescopic rack of the new energy battery pack in this application embodiment is as follows: First, the central connecting component is fixed on the machine base 2 by the placement seat, the corner support frame 12 is placed on the corresponding third sliding plate 33 by the detection seat 331, the wide side connecting frame 14 is placed on the second sliding plate 32 at the corresponding side position by the detection seat 331 and the placement seat on the corresponding second sliding plate 32, and similarly, the long side connecting frame 13 is placed on the first base plate; then, taking the corner support frame 12 as an example, the deflection drive component 421 on the third sliding plate 33 The deflection plate 422 is rotated, causing the end of the deflection plate 422 away from the mounting base 332 to move directly above the first connection port 121. The controller 21 controls the pressing drive to press the first abutting plate 4232 against the upper surface of the corner support frame 12. Simultaneously, the second pressing drive installed on the detection base 331 drives the second abutting plate 4242 to press against the outer wall of the first connection port 121. At this time, the first abutting plate 4232 and the other three sets of second abutting plates 4242 are combined to form a repair frame, which is fitted onto the first connection port 121.

[0084] During this process, if the first connection port 121 does not deform, the values ​​measured by the distance sensor 4239 on the corresponding repair frame will all be the same, and the controller 21 will also take the value obtained by the distance sensor 4239 on the first connection port 121 as the standard value, since the first connection port 121 is not deformed. If a side of the first connection port 121 is deformed inward, when the corresponding side is pressed by the abutment plate, the end of the piston rod with the hemispherical surface at the concave position will not be effectively squeezed, thus causing the value obtained by the distance sensor 4239 at one end of the display tube 4237 to be less than the standard value. If a side of the first connection port 121 is deformed outward, during the pressing process of the abutment plate, the piston rod on the abutment plate on the corresponding side will be squeezed before other positions, and the controller 21 will obtain the value at that position, which is less than the standard value.

[0085] In summary, the connection points on each component can be inspected before formal assembly, thereby avoiding the inability to assemble components smoothly due to deformation of the connection points.

[0086] Next, the controller 21 will perform targeted emergency repairs on the first connection port 121 according to the actual type of deformation. When an inward deformation is detected in the first connection port 121, the controller 21 controls the detection arm 411 to move above the corresponding first connection port 121, the reversing component 415 rotates to align the repair roller 432 with the first connection port 121, and the controller 21 controls the slide to move on the sliding beam 414, so that the repair roller 432 is inserted into the first connection port 121. Since the cross-section of the repair roller 432 is set to a Reuleaux triangle shape, and each side of the Reuleaux triangle is a curve of fixed width, and the connecting shaft 4321 is eccentrically set with the central axis of the repair roller 432, the outer contour trajectory of the repair roller 432 is square. At this time, the first connection port 121 is also square. With the limit of the repair frame, as the repair roller 432 rotates and inserts, the inward deformation is gradually repaired.

[0087] When the first connection port 121 is detected to have an outward bulge deformation, the repair roller 432 is no longer able to repair this type of deformation. At this time, it is only necessary to control the pressing drive to drive the abutment plate to squeeze the outward bulge deformation inward to achieve emergency repair of the outward bulge deformation.

[0088] It should be noted that, in order to ensure the stability of the entire telescopic rack, the first insertion part 111 and the first connection port 121 are shaped to fit each other. Therefore, if the first connection port 121 is deformed, the two will not be able to be inserted smoothly. At the same time, a certain degree of slight deformation is difficult to detect by human visual inspection during the assembly process, and will only be noticeable during actual assembly.

[0089] Next, the detection arm 411 moves the test assembly 44 to the end of the first insertion part 111 facing the first connection port 121. The detection arm 411 inserts the connecting part 4421 of the punch plug 442 into the end of the first insertion part 111. The clamping drive 441 releases the clamp on the locking plate 4431. The end of the locking pin 4433 away from the locking plate 4431 engages with the pre-set bolt mounting hole on the first insertion part 111. The detection arm 411 moves backward and upward, and then the translation drive 452 moves the extension seat 4. 51 moves closer to the detection seat 331, so that the horizontal correction group and the vertical correction group face the end of the first insertion part 111 facing the first connection port 121. Then the controller 21 drives the first connection port 121 to move closer to the first insertion part 111. The correction roller 454 set on the extension seat 451 forcibly straightens the first insertion part 111. The punch plug 442 is inserted into the first connection port 121 along with the first insertion part 111. The friction ring 4422 removes burrs from the inner cavity of the first connection port 121 to ensure smooth insertion and mating.

[0090] In summary, the inspection and repair of the joints and plugs on the remaining components are carried out in the same manner. It is worth noting that in this embodiment, the deformation of the joints is inspected and repaired first, followed by the correction of the plugs and the internal cavity treatment of the joints. Therefore, multiple sets of punch plugs 442 are provided, and the order in which the punch plugs 442 are installed on the plugs of the entire material rack follows... Figure 1 The assembly is carried out sequentially from left to right and from top to bottom. After all components are installed, trial assembly of each component begins, during which the inner cavity of the connection joint is treated. In addition, the assembly sequence of the entire telescopic material rack is as follows: the corner support frame 12 first moves towards the long side connecting frame 13, then towards the wide side connecting frame 14, and finally the connections between each component are tightened with bolts to complete the assembly of the entire telescopic material rack.

[0091] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
