Description

Technical Field

[0001] The present invention relates to the technical field of power battery disassembly and assembly equipment, and in particular to a power battery quick disassembly and assembly device. Background Art

[0002] Existing power battery removal and assembly technology has numerous shortcomings: Traditional removal and assembly tools cannot adaptively adjust to the height and inclination of the battery box, making it difficult to precisely align the power battery mounting surface with the transfer platform. During the removal and assembly process, the power battery is primarily transferred to the battery box and then manually pushed in. This method is not only inefficient but also poses safety risks. While existing warehousing and logistics loading and unloading tools can perform basic handling functions, they are unable to precisely remove and assemble power battery packs within the limited assembly space of the battery box. This is particularly true when removing and installing power batteries on specialized equipment such as mining trucks, where traditional tools cannot meet the requirements of operating in confined spaces. Furthermore, existing tools lack a reliable battery capture mechanism, preventing the automatic capture and release of the power battery pack, making the removal and assembly process time-consuming and labor-intensive. Regarding platform lifting and lowering controls, traditional hydraulic transmission systems suffer from slow response speeds and poor positioning accuracy, making precise adjustment at multiple angles difficult. Existing technologies also lack effective solutions for buffer protection between the power battery pack and the transfer platform, making the battery pack susceptible to damage during the removal and assembly process.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limiting the present invention.

Thus, a feature identified as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0025] Reference below Figures 1 to 6 The power battery quick disassembly and assembly device in an embodiment of the present invention is described.

[0026] The embodiment of the present application discloses a power battery quick disassembly and assembly device, including: a frame 8 and wheels installed at the bottom of the frame 8, an electric cylinder 10 and a power source 7 installed on the frame 8, a transfer platform 1, a universal joint 11 and a control end 3.

[0027] Four sets of electric cylinders 10 are provided, all arranged vertically. Two sets of electric cylinders 10 are symmetrically arranged at the front of the vehicle frame 8, and the other two sets are symmetrically arranged at the rear of the vehicle frame 8. Together, these four sets of electric cylinders 10 support the transfer platform 1. Each electric cylinder 10 has a universal joint 11 installed at the free end of its telescopic rod, which secures it to the bottom of the transfer platform 1. A control terminal 3 is mounted at the rear end of the transfer platform 1, and each electric cylinder 10 is connected to the control terminal 3 for signal transmission. The transfer platform 1 includes a battery capture device 13, which is used to capture or release the power battery pack 2. The battery capture device 13 is connected to the control terminal 3 for signal transmission, which controls the movement of the battery capture device 13 and receives position signals from the battery capture device 13. A push-pull handle is provided at the rear end of the vehicle frame 8 for easy operation. A standard charging port 5 is provided on the side of the power source 7, ensuring energy conservation, environmental protection, and ease of maintenance.

[0028] The frame 8 is the framework of the main structure of the load-bearing device, which is used to fix the electric cylinder 10 and the power source 7. The electric cylinder 10 is an actuator that realizes linear motion by driving a lead screw through a motor. Specifically, a servo electric cylinder 10 can be used. Its independent lifting ability supports multi-dimensional adjustment of the platform. The universal joint 11 is a connector with multi-degree-of-freedom rotation function. Specifically, a ball joint structure can be used to compensate for the angular deviation between the electric cylinder 10 and the platform. A tension sensor 12 is also provided on the universal joint 11. The tension sensor 12 is connected to the control terminal 3 signal, which is used to monitor the abnormal state of the electric cylinder 10. The transfer platform 1 is a load-bearing component for installing a battery capture device 13. The control terminal 3 is a human-computer interaction interface that integrates control buttons and signal processing modules. Specifically, an industrial controller with a touch screen can be used to send instructions and receive sensor data. Wheels are provided at the four corners of the bottom of the frame 8, including fixed wheels 9 and universal wheels 6. The two front wheels of the frame 8 are fixed wheels 9, and the two rear wheels are universal wheels 6. The universal wheels 6 can realize steering and adjust the angle posture of the device. When the device needs to be fixed, the front fixed wheels 9 and the rear universal wheels 6 both have locking functions.

[0029] Specifically, four groups of electric cylinders 10 independently control the lifting height of different areas of the transfer platform 1. The extension and contraction of each group of electric cylinders 10 are adjusted through the control terminal 3 so that the platform surface and the battery box installation surface are parallel or at a preset angle. The universal joint 11 automatically adapts to the change in platform angle during the adjustment process to avoid structural interference. When the platform completes the posture calibration, the control terminal 3 activates the battery capture device 13, obtains the position of the power battery pack 2 in real time through signal interaction, and drives the robotic arm to perform grasping or releasing actions. The built-in sensor of the electric cylinder 10 monitors pressure and displacement data, and sends an alarm to the control terminal 3 in an abnormal state and triggers emergency stop protection.

[0030] Compared to existing technologies, traditional tools using single-point lifting or manual adjustment cannot achieve fine-tuning of the platform's inclination angle. However, the coordinated control of four electric cylinders 10 precisely matches the spatial orientation of the battery box mounting surface. Existing capture devices are mostly independent mechanical structures lacking coordinated control with the lifting platform. This solution automates the assembly and disassembly process through signal integration, significantly reducing the need for manual intervention. Compared to hydraulic transmission, the closed-loop control characteristics of the electric cylinders 10 improve response speed and positioning accuracy.

[0031] Through the above-mentioned technical solution, this application achieves real-time adaptation of the platform height and inclination during assembly and disassembly of the power battery pack 2, resolving the problem of traditional tools being unable to align the mounting surface. The signal linkage between the control terminal 3 and the actuator creates automated control, eliminating the safety risks of manual push-pull operations. The coordinated design of the universal joint 11 and the sensor enhances system stability, ensuring a smooth transition of the power battery under complex operating conditions.

[0032] In some embodiments, for example Figure 2 and Figure 4 As shown, the transfer platform 1 further includes a platform frame 11 and a chain transmission system 12 . The chain transmission system 12 is arranged on the platform frame 11 , and the battery capture device 13 is installed on the platform frame 11 through the chain transmission system 12 .

[0033] Furthermore, the platform frame 11 includes a front end fixed beam 111, a rear end fixed beam 112, a middle fixed beam 113, a transmission chain frame 114 and a positioning buffer block 115. The front end fixed beam 111 is fixedly installed at the front end bottom of the transmission chain frame 114, the rear end fixed beam 112 is fixedly installed at the rear end of the transmission chain frame 114 and wraps the left and right sides of the transmission chain frame 114, a plurality of middle fixed beams 113 are provided, and the multiple middle fixed beams 113 are evenly spaced and arranged in the middle of the transmission chain frame 114, and two positioning buffer blocks 115 are provided, and the two positioning buffer blocks 115 are respectively fixedly installed on the front end surfaces on the left and right sides of the transmission chain frame 114.

[0034] Among them, the front-end fixed beam 111 is a transverse support component installed at the bottom of the front end of the transmission chain frame 114. Specifically, it can be fixed by welding or bolting. The bottom fixation form enhances the bending resistance of the front end of the frame. The rear-end fixed beam 112 is a composite structural component that wraps the rear end and left and right sides of the transmission chain frame 114. Specifically, it can be implemented by a U-shaped cross-section component to form a full-circle fixed constraint on the rear part of the transmission chain frame 114 to prevent the chain from shifting laterally. The middle fixed beam 113 is a transverse support component distributed at intervals along the length direction of the transmission chain frame 114. It improves the bending section modulus of the middle part of the frame through multi-point support. The transmission chain frame 114 is the main support structure of the load-bearing chain transmission system 12 and provides a reference track for the chain operation. The positioning buffer block 115 is a buffer component made of elastic material. Specifically, it can be implemented by a polyurethane block or a rubber block. Its outer contour is designed as a conical structure to disperse collision stress.

[0035] Specifically, the front-end fixed beam 111 strengthens the rigidity of the front end of the transmission chain frame 114 by fixing it at the bottom, preventing the front end from deforming due to stress during sprocket operation. The rear-end fixed beam 112 adopts a wrap-around mounting structure, which not only fixes the rear end of the transmission chain frame 114 but also forms a physical limit for the running trajectory of the rear section of the chain. Multiple middle fixed beams 113 are evenly distributed along the longitudinal direction of the transmission chain frame 114, distributing the load by increasing the density of support points, effectively suppressing the flexural deformation of the frame during long-stroke transmission. The transmission chain frame 114 serves as an integrated support base, providing a precise installation reference surface for the sprocket assembly and guide wheel assembly, ensuring the straightness of the chain running trajectory. The various structural components are arranged in a hierarchical manner to form a spatial truss system, which improves the overall torsional resistance of the frame. The positioning buffer blocks 115 are installed in left-right symmetrical positions on the front end of the transmission chain frame 114 by bolting. When the transfer platform 1 is pushed toward the battery box for docking, the two positioning buffer blocks 115 preferentially contact the edge of the battery box, and the elastic material deforms to absorb the kinetic energy of the collision. Symmetrically arranged buffer blocks create equal reaction forces on both sides at the moment of contact, offsetting platform deflection caused by unilateral load. After absorbing the impact, the front-mounted buffer block's tapered structure guides the transfer platform 1 and the battery box to automatically align their centers, achieving coarse positioning. Damaged buffer blocks can be replaced individually by removing the bolts, eliminating the need to replace the entire drive chain frame 114.

[0036] Through the above design, the present application effectively improves the overall structural stability of the platform frame 11, the transmission chain system maintains a linear motion trajectory during long-stroke operation, and the frame deformation is controlled within the allowable range, providing a precise translation reference for the capture device, ensuring that the positioning accuracy of the power battery pack 2 meets the operational requirements during the disassembly and assembly process. At the same time, it effectively alleviates the impact load when the transfer platform 1 is docked with the battery box, preventing the equipment and battery box from suffering structural damage due to rigid collision. The symmetrically distributed buffer blocks maintain the balance of the platform during propulsion, avoiding offset and jamming caused by unilateral force.

[0037] Furthermore, the chain transmission system 12 includes a transmission sprocket group, a driven sprocket group and a guide sprocket group. The transmission sprocket group consists of a transmission device 121, a transmission chain shaft 122, a transmission sprocket 123, a transmission chain 124, a plastic liner 125 and a link pin 126. The transmission device 121 is connected to the control end 3 signal. The transmission chain 124 is provided with two and is arranged on the left and right sides of the transmission chain frame 114 respectively. The driven sprocket group consists of a driven sprocket, and the guide sprocket group consists of a guide sprocket 128, a guide chain shaft 129 and a guide The transmission device 121 drives the transmission chain 124 through the transmission chain shaft 122 and the transmission sprocket 123 in turn, and the driven sprocket 127 engages with the transmission chain 124 to realize power transmission. There are two guide sprockets 128, and the two guide sprockets 128 are respectively engaged with the transmission chains 124 on the left and right sides to guide the chain running path; a plastic pad 125 is installed on the upper chain link of the transmission chain 124, and the plastic pad 125 is fixed to the chain link of the transmission chain 124 through a link pin 126.

[0038] Among them, the transmission sprocket group is a component that transmits the power output by the transmission device 121 to the transmission sprocket 123 through the transmission chain shaft 122, driving the transmission chain 124 to run. Specifically, a servo motor can be used as the transmission device 121, connected to the transmission chain shaft 122 through a coupling to achieve precise control of the power source 7. The driven sprocket group is a sprocket that meshes with the transmission chain 124 and transmits power as it moves. A double-row sprocket structure is used to adapt to the left-right symmetrical arrangement of the transmission chain 124 to ensure that the chains on both sides run synchronously. The guide sprocket group is a component set at the turning point of the chain path to guide the direction of the chain. Specifically, a guide sprocket 128 with a self-lubricating bearing can be used. It is fixed to the transmission chain frame 114 through the guide chain bearing seat 130 to prevent the chain from running off the track or derailing. The plastic pad 125 is a buffer material fixed to the surface of the chain link. It can be made of polyurethane or nylon. It can be detachably installed on the upper surface of the chain through the connecting pin 126 to reduce rigid friction when contacting the power battery pack 2.

[0039] Specifically, after receiving the instruction from the control end 3, the transmission device 121 drives the transmission chain shaft 122 to rotate, driving the transmission sprocket 123 to rotate, thereby pulling the transmission chain 124 to run along the preset path. The left and right side transmission chains 124 are arranged in parallel, and the driven sprocket group provides support and power reception at the end of the chain to ensure uniform chain tension. The guide sprocket group is installed at the turning point of the chain, and adjusts the direction of the chain through the meshing relationship to avoid jamming due to path deviation. The plastic pad 125 covers the upper surface of the chain. When the power battery pack 2 moves on the chain, the surface wear is reduced through elastic contact. The combined design of the transmission sprocket group and the guide sprocket group realizes the precise control of the chain path, and cooperates with the buffering effect of the plastic pad 125 to form a stable and low-friction transmission environment.

[0040] Through the above design, the present application solves the problem of transmission instability caused by loose or overtightened chains, realizes precise control of the running path through the guide sprocket group, and reduces abnormal wear of the chain and sprocket; the buffering effect of the plastic pad 125 avoids surface damage of the power battery pack 2 due to rigid contact during transportation; the split sprocket group design improves the power transmission efficiency, ensures the synchronous operation of the left and right chains, and provides a structural basis for subsequent tensioning adjustment.

[0041] In some embodiments, for example Figure 4 As shown, the battery capture device 13 includes a transmission motor 131, a transmission gear 132, a left capture arm 133, a right capture arm 134, a capture housing 135, a cover 136, a housing fixing pin 137 and a positioning device 138. The left and right sides of the capture housing 135 are respectively fixed to the chain links of the transmission chain 124 on the left and right sides through the housing fixing pin 137. Part of the left capture arm 133 and the right capture arm 134 are located in the capture housing 135 and the arm surfaces of the left and right capture arms in the capture housing 135 are both provided with rack tooth surfaces 1334. The transmission motor 131 is installed in the capture housing 135. 5 and meshes with the rack tooth surfaces 1334 of the left and right capture arms at the same time through the transmission gear 132 to drive the left and right capture arms to move synchronously toward or in the opposite direction. The cover 136 is provided on the upper end surface of the capture shell 135. There are two positioning devices 138, which are respectively installed on the left and right sides of the capture shell 135; the transmission motor 131 and the positioning device 138 are both connected to the control end 3 by signal; a guide bell mouth 1121 is provided on the rear end fixed beam 112, and the transmission motor 131 is reset through the guide bell mouth 1121 when it retreats to the rear end of the transfer platform 1.

[0042] The positioning device 138 is a sensor module installed on both sides of the capture housing 135. Specifically, it can be implemented as a contact limit switch or a photoelectric sensor. It is used to detect the actual contact state between the capture arm and the power battery pack 2 and feedback the position signal to the control terminal 3. The guide bell mouth 1121 is an opening structure provided on the rear fixed beam 112. Its function is to guide the transmission motor 131 to accurately return to its original position when the capture device is reset, avoiding mechanical jamming.

[0043] Specifically, the transmission motor 131 simultaneously engages the rack tooth surfaces 1334 of the left and right capture arms through the transmission gear 132. When the transmission gear 132 rotates, it drives the racks on both sides to move synchronously in opposite directions, so that the left and right capture arms always maintain symmetrical displacement. The capture shell 135 is fixed to the chain link of the transmission chain 124 through the shell fixing pin 137, and drives the entire capture device to move along a preset path during chain transmission. The positioning device 138 monitors the contact status between the capture arm and the power battery pack 2 in real time. When it detects that the positioning pin 1333 enters the battery pack lifting hole, it immediately sends a positioning signal to the control end 3 to stop the operation of the transmission motor 131. During the rear-end reset process, the guide bell mouth 1121 automatically corrects the position deviation of the transmission motor 131 through a gradually expanding structure to ensure that the capture device accurately returns to its initial position.

[0044] Through the above-mentioned technical solution, the present application achieves precise synchronous control of the capture arm during push-pull movements. The synergistic effect of the bilateral positioning device 138 and the guide bell mouth 1121 solves the problem of positional deviation during the resetting of the capture device. The bilateral signal acquisition mechanism of the positioning device 138 ensures the reliability of the capture action and significantly reduces the error rate.

[0045] In some embodiments, for example Figure 4 and Figure 5 As shown, the left capture arm 133 and the right capture arm 134 are both composed of a large arm 1331, a small arm 1332 and a positioning pin 1333. The large arm 1331 is in a Z-shaped stepped shape. A rack tooth surface 1334 is provided on the Z-shaped lower step surface of the left capture arm 133, and a rack tooth surface 1334 is provided on the back of the Z-shaped upper step surface of the right capture arm 134. The rack tooth surface 1334 of the left capture arm 133 is opposite to the rack tooth surface 1334 of the right capture arm 134 up and down. The large arm 1331 is located in the capture shell 135, and the positioning pin 1333 is installed on the front inner side of the small arm 1332. The Z-shaped upper step surface of the right capture arm 134 is flush with the Z-shaped upper step surface of the left capture arm 133, and the Z-shaped lower step surface of the right capture arm 134 is flush with the Z-shaped lower step surface of the left capture arm 133, and the front and back faces of the large arms 1331 of both are on the same plane. A laterally extending raised step 1335 is further provided on the small arm 1332 behind the locating pin 1333. The front side surface of the raised step 1335 and the front inner side surface of the small arm 1332 behind the locating pin 1333 serve as a cushion mounting surface 1336. A cushion 1337 is mounted on the cushion mounting surface 1336. A laterally extending raised step 1335 is further provided on the small arm 1332 behind the locating pin 1333. The front side surface of the raised step 1335 and the front inner side surface of the small arm 1332 behind the locating pin 1333 serve as a cushion mounting surface 1336. A cushion 1337 is mounted on the cushion mounting surface 1336.

[0046] Among them, the Z-shaped stepped upper arm 1331 is a stepped structure with an upper and lower offset, which can be specifically realized by stamping or machining. This structure enables the rack tooth surfaces 1334 of the left and right capture arms to be arranged in an upper and lower offset manner and to form a symmetrical meshing with the transmission gear 132. The locating pin 1333 is a cylindrical positioning component, the diameter of which matches the size of the lifting hole of the power battery pack 2, and is used to insert the lifting hole during the capture process to achieve precise positioning. The raised step 1335 is a lateral extension structure on the inner side of the front end of the small arm 1332, which can be specifically realized by welding or integral molding. The front side surface and the inner side surface of the small arm 1332 behind the locating pin 1333 form a plane area for installing a buffer pad 1337 to cover the force-bearing area during the pushing and pulling process.

[0047] Specifically, the upper arms 1331 of the left and right capture arms adopt a Z-shaped stepped structure, so that the rack tooth surface 1334 of the left capture arm 133 is located on the lower stepped surface, and the rack tooth surface 1334 of the right capture arm 134 is located on the back of the upper stepped surface. The two are opposite each other and form a symmetrical mesh with the transmission gear 132. This arrangement allows the transmission gear 132 to apply a uniform force to both tooth surfaces simultaneously when driven, maintaining the synchronous movement of the left and right capture arms. The positioning pin 1333 is directly fixed to the inner side of the front end of the small arm 1332. During the capture action, it is inserted into the lifting hole on the side of the power battery pack 2, and precise positioning is achieved through the hole-pin fit. The raised step 1335 is set on the small arm 1332 behind the positioning pin 1333. Its front side and the inner side of the front end of the small arm 1332 together form the installation area of ​​the buffer pad 1337, so that the buffer pad 1337 can simultaneously cover the positive contact surface when pushing in and the negative contact surface when pulling out. The front and rear surfaces of arm 1331 remain flush, forming surface contact with the guide rollers within capture housing 135, ensuring that the left and right capture arms do not deflect during movement. The Z-shaped stepped structure maintains the overall compactness of arm 1331 while accommodating the staggered tooth arrangement. This allows the transmission and buffer paths to be integrated into the same component, eliminating the transmission backlash caused by the additional buffer.

[0048] Through the above technical solution, the present application realizes bidirectional buffering and energy absorption when the capture arm pushes and pulls the power battery pack 2, effectively absorbing the vibration caused by the impact force and preventing the positioning pin 1333 from displacement deviation due to the impact. The integrated buffer structure avoids the influence of additional components on the transmission accuracy and ensures the stability of the capture arm during movement. The Z-shaped stepped tooth surface structure makes the transmission gear 132 symmetrical in force, improves the synchronization accuracy of the left and right capture arms, and reduces the risk of equipment wear caused by asynchrony.

[0049] In some embodiments, multiple fixed roller seats 1351 are provided on the bottom of the capture housing 135 and the inner side of the cover 136. Each fixed roller seat 1351 on the capture housing 135 is provided with multiple upper guide rollers, and each fixed roller seat 1351 on the cover 136 is provided with multiple lower guide rollers 1361. The upper guide rollers and lower guide rollers 1361 respectively contact the lower and upper sides of the left and right capture arms 1331. Multiple vertical guide rollers 139 are provided between the front and rear sides of the left and right capture arms 133 and 134 and the inner side of the capture housing 135. The upper and lower ends of the vertical guide rollers 139 are respectively mounted on the bottom surface of the capture housing 135 and the inner side of the cover 136. A buffer disc spring 140 is installed between each pair of adjacent vertical guide rollers 139 and the adjacent inner side of the capture housing 135.

[0050] Among them, the fixed roller seat 1351 is a support structure for installing the guide roller, which is welded to the corresponding position on the bottom surface of the capture shell 135 and the inner side of the cover 136. The guide roller is a cylindrical roller with a rolling bearing. The upper guide roller and the lower guide roller 1361 are respectively arranged on the upper and lower sides of the capture arm arm 1331 to form rolling contact. The vertical guide roller 139 is a guide roller arranged perpendicular to the movement direction of the capture arm. Its two ends are fixed to the long holes on the bottom surface of the capture shell 135 and the inner side of the cover 136 by slots or screws, allowing displacement along the length of the hole. The buffer disc spring 140 is a disc spring assembly with elastic deformation ability. Specifically, it can be realized by using multiple layers of superimposed conical spring steel sheets. When it is compressed, it generates a reverse force to absorb impact energy.

[0051] Specifically, when the capture arm performs a push-pull motion within the housing, the upper and lower surfaces of its upper arm 1331 form rolling contact with the upper guide roller and the lower guide roller 1361, converting the original sliding friction into rolling friction, effectively reducing the resistance to movement. The vertical guide rollers 139 are distributed along the front and rear sides of the capture arm. By fixing the capture arm at the upper and lower ends, the movement trajectory of the capture arm within the housing is constrained to prevent lateral displacement caused by force. When the capture arm is subjected to an impact load in the push-pull direction, the vertical guide rollers 139 are displaced within the long hole and squeeze the adjacent buffer disc spring 140. The disc spring absorbs the impact energy through elastic deformation, preventing rigid collisions from causing structural damage to the housing or the capture arm.

[0052] Through the above technical solution, the present application solves the problem of component wear caused by rigid impact when the capture device pushes and pulls the power battery pack 2, and significantly reduces friction loss through the rolling guide structure; achieves precise guidance of the capture arm's movement in the shell; the elastic deformation of the buffer disc spring 140 can absorb instantaneous impact loads and avoid plastic deformation of structural parts.

[0053] In some embodiments, for example Figure 4As shown, the transfer platform 1 also includes a chain tensioning device 14, which includes a fixed shaft 141, an adjusting shaft 142, a tensioning screw 143, an adjusting seat 144 and a fixed seat 145. The fixed shaft 141 and the adjusting shaft 142 are installed on the platform frame 11 with a front-to-back interval. The left and right ends of the fixed shaft 141 are symmetrically installed with fixed seats 145 in series, and the left and right ends of the adjusting shaft 142 are symmetrically installed with adjusting seats 144 in series. The assembly points of the transmission chain frames 114 and the adjusting shafts 142 on the left and right sides of the platform frame 11 are designed with long strip holes along the length direction of the chain frames, so that the adjusting shaft 142 can translate back and forth in the long strip holes, and the fixed seat 145 and the adjusting seat 144 are connected through a tensioning screw 143.

[0054] Among them, the fixed shaft 141 is a shaft body used to fix the position of the chain tensioning device 14, which is used to maintain the structural stability of the tensioning device. The adjusting shaft 142 is a movable shaft body used to adjust the tightness of the chain. It translates within the range of the long strip hole to change the effective length of the chain. At the same time, the adjusting shaft 142 can also fix the driven sprockets 127 at both ends. The tensioning screw 143 is a threaded rod used to drive the adjusting shaft 142 to move, which generates an axial displacement difference through rotation. The adjusting seat 144 is a component installed at both ends of the adjusting shaft 142 and connected to the tensioning screw 143. Its internal thread matches the rotation direction of one end of the tensioning screw 143, and is used to convert the rotational motion of the screw into a linear displacement of the adjusting shaft 142. The fixed seat 145 is a component installed at both ends of the fixed shaft 141 and connected to the tensioning screw 143. Its internal thread has an opposite rotation direction to the other end of the tensioning screw 143, and a two-way adjustment function is achieved through reverse thread matching. The long strip hole is a guide groove provided on the transmission chain frame 114 for the adjustment shaft 142 to slide.

[0055] Specifically, when the transmission chain 124 becomes loose due to long-term use, the adjustment seat 144 can be driven to move along the axial direction of the screw by rotating the tensioning screw 143. Since the thread rotation directions of the fixed seat 145 and the adjustment seat 144 are opposite, when the screw is rotated, the adjustment seats 144 on both sides move in opposite directions at the same time, driving the adjustment shaft 142 to translate in the elongated hole. When the adjustment shaft 142 moves away from the fixed shaft 141, the effective length of the transmission chain 124 is shortened and the chain tension increases; conversely, when the adjustment shaft 142 moves toward the fixed shaft 141, the chain tension decreases. The transmission chain frames 114 on both sides of the platform frame 11 are provided with independent elongated holes and tensioning screw 143 assemblies, allowing the tightness of the transmission chains 124 on the left and right sides to be adjusted independently and differentially.

[0056] Through the above technical solution, this application solves the problems of transmission lag and positioning deviation caused by chain slack, effectively prevents chain tooth skipping and abnormal wear, and ensures the movement accuracy of the capture device when pushing and pulling the power battery pack 2. The dual-side independent adjustment function can adapt to the asymmetric wear conditions of the left and right chains, extending the service life of the transmission system while simplifying maintenance operations.

[0057] In some embodiments, for example Figure 3 As shown, the control end 3 is provided with control buttons, which include a start-stop area button, a platform lifting area button and a pack control area button. The start-stop area button is used to control the start-stop and lifting speed of the electric cylinder 10, the start-stop and operating speed of the transmission device 121 and the transmission motor 131, the platform lifting area button is used to control the lifting of the electric cylinder 10, and the pack control area button is used to control the forward and reverse rotation of the transmission device 121 and the transmission motor 131. The start-stop area buttons include five buttons, namely "slow up", "slow down", "fast up", "fast down" and "stop"; the platform lifting area buttons respectively control the compound action of the four electric cylinders 10, and the compound action includes the synchronous action of any two adjacent electric cylinders 10, the synchronous action of any three electric cylinders 10, and the synchronous action of four electric cylinders 10. The platform lifting area buttons include "AB", "AC", "BD", "CD", "B C", "A D", "A D", "B There are nine buttons in total, namely, "C", "ABCD", among which A, B, C, and D are the numbers of the four electric cylinders 10. The large letters are used to indicate that the corresponding electric cylinder 10 has a faster movement speed than the two adjacent electric cylinders 10. At the same time, the movement speeds of the two adjacent electric cylinders 10 are the same; the pack control area buttons include four buttons, namely "retract", "release", "push", and "pull".

[0058] Among them, the start and stop zone buttons are used to match different working conditions through five-speed adjustment, which can be implemented by physical buttons with tactile feedback or virtual buttons on the touch screen. The speed is fine-tuned by controlling "slow up" and "slow down", fast displacement is achieved by "fast up" and "fast down", and "stop" is used as an emergency brake to solve the problem of insufficient speed regulation accuracy of traditional hydraulic systems. The platform lifting zone button is a collaborative control interface of the electric cylinder 10 based on letter combination coding, and the speed ratio calculation of the electric cylinder 10 can be implemented by an embedded control system. The electric cylinder 10 marked with large letters can be set to run at a speed 1.5-2 times that of the two adjacent cylinders. For example, in "B In the "C" combination, the speed of cylinder A is 1.8 times that of cylinders B and C, thereby achieving rapid compensation for platform inclination. The pack control area button is a composite control component that links the transmission chain 124 and the capture arm. Specifically, it can be implemented using a dual-channel signal controller. When the "push" button is triggered, the transmission device 121 runs forward while the capture arm remains in a clamping state, ensuring the synchronization of power battery delivery.

[0059] Specifically, the control terminal 3 implements hierarchical control through functional zoning. The buttons in the start / stop zone serve as the basic control layer, prioritizing speed commands when powered on. For example, when the "Quick Down" button is activated, all four electric cylinders 10 descend at maximum speed. The buttons in the platform lift zone serve as the posture adjustment layer. Within the speed mode selected in the start / stop zone, a letter combination selects the action group of the electric cylinders 10. For example, selecting the "AC" button causes cylinders A and C to operate at the same speed. Combined with the start / stop zone's "Slow Up" mode, this allows for a synchronized slight lift of the left front and right rear corners. The pack control zone serves as the operation execution layer. During the operation of the transmission chain 124, when the "Collect" button is triggered, the transmission motor 131 drives the rack-and-pinion mechanism to clamp the capture arm. The "Pull" button, however, reverses the transmission mechanism 121, driving the power battery toward the transfer platform 1. The operation process employs a sequential logic of "selecting the mode first, then the action." For example, to adjust the platform's inclination, the speed range in the start / stop zone must be selected first, followed by triggering the combination buttons in the platform lift zone.

[0060] Compared with the existing technology, the control system of the existing power battery disassembly and assembly equipment usually adopts a single speed adjustment knob with an independent electric cylinder 10 switch. When operating, it is necessary to repeatedly switch different control panels, making it difficult to achieve multi-axis coordinated action. However, this solution uses button function partitioning and combination coding design to enable the operator to complete complex posture adjustments through a single operation combination, such as "B The "C" combination button can simultaneously control the three electric cylinders 10 to operate at different speeds, quickly compensating for height differences while maintaining platform stability. Compared to traditional equipment that can only control the movement of a single electric cylinder 10 at a time, this solution solidifies the multi-axis linkage operation under typical working conditions into a preset mode, significantly reducing adjustment time.

[0061] Through the above technical solution, the present application realizes multi-dimensional precise adjustment of the transfer platform 1, and quickly adapts to different tilt conditions through nine preset electric cylinder 10 combination modes, shortening the traditional platform leveling process that requires step-by-step operation to a single combination operation. The coordinated design of the five-speed control and the four function buttons enables the clamping and conveying actions in the power battery capture process to be completed synchronously, which significantly reduces the number of operating steps compared to the separate control of the existing technology that requires separate operation of the robotic arm clamping and the conveyor belt operation. The intuitive coding method of the button layout avoids the risk of misoperation. For example, the letter size difference design of the platform lifting area button enables the operator to intuitively identify the main control electric cylinder 10, ensuring the safety of the execution of complex actions.
