Description

Technical Field

[0001] The present disclosure relates to the technical field of assembly and shaping of multiple rows of battery modules, and in particular to an assembly and shaping device for multiple rows of battery modules. Background Art

[0002] Before new energy battery modules are loaded into battery boxes, multiple rows of modules must be shaped to ensure they meet dimensional requirements in length, width, and height. Multiple single-row modules must then be assembled to improve subsequent boxing efficiency. In related technologies, an AGV (Automated Guided Vehicle) is attached to multiple pallets, each of which holds a battery module. After the AGV enters the assembly and shaping equipment, workers manually center the AGV and then use a push mechanism to shape and assemble the battery modules on the pallets. However, this method is labor-intensive for workers. Summary of the Invention

[0056] The following describes the specific embodiments of the present disclosure in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure and are not intended to limit the present disclosure.

[0057] In this disclosure, unless otherwise indicated, directional terms such as "upper, lower, front, rear, left, and right" are used for ease of description and are defined based on the drawing orientation of the corresponding drawings. "Inside" and "outside" are defined based on the inherent contours of the corresponding components. Terms such as "first" and "second" used in this disclosure are intended to distinguish one element from another and do not convey order or importance. Furthermore, when the following description refers to the drawings, unless otherwise indicated, identical numbers in different drawings represent identical or similar elements.

[0058] See also Figures 1 to 3 The present disclosure provides a multi-row battery module assembly and shaping device, comprising a platform positioning mechanism 1, a width reference clamping mechanism 2, a width clamping mechanism 8, a tray unlocking mechanism 3, a length shaping mechanism 4, and a length reference clamping mechanism 5. The platform positioning mechanism 1 comprises a frame 102, which is connected to the ground via a base plate 101. The frame 102 is connected by a crossbeam 14 and a column 113. Figure 1 and Figure 2 It should be explained that the crossbeams 14 in the adjustment chamber are to facilitate the stability of the frame 102 during transportation and movement. After the frame 102 is fixed to the ground, the three crossbeams 14 in the adjustment chamber will be removed to ensure that the AGV trolley can enter the adjustment chamber. The frame 102 is provided with an adjustment chamber, in which two length-direction fixed blocks 105, two length-direction pushers 104, two width-direction fixed blocks 111, two width pushers 106 and a plurality of bull's eye bearings 112 are respectively installed. The bull's eye bearings 112 are used to contact the bottom of the burrs on both sides of the trolley. The width reference clamping mechanism 2 and the width clamping mechanism 8 are respectively installed on both sides of the width direction of the adjustment chamber for assembling multiple rows of battery modules. The tray unlocking mechanism 3 is provided in the adjustment chamber for releasing the length-direction restriction of the tray on the battery module. The length shaping mechanism 4 and the length reference clamping mechanism 5 are respectively installed on both sides of the length direction of the adjustment chamber for approaching each other to adjust the length of the battery module.

[0059] It can be understood that the entry detection switch 110 is installed in the adjustment chamber to detect the entry of the AGV trolley. The AGV trolley enters the adjustment chamber after passing the follower 103. At this time, the trays on both sides of the AGV trolley will be overlapped on the bull's eye bearing 112. After the barcode scanner 107 recognizes the AGV trolley, the cylinder pins 108 installed on both sides of the width direction of the adjustment chamber will extend to push the tray to the left or right, thereby allowing the AGV trolley to move left or right. This step belongs to the rough adjustment of the AGV trolley in the width direction. After adjustment, the cylinder pin 108 will be retracted, and a ventilation joint 109 will be installed on the cylinder pin 108, and the gas enters the cylinder through the ventilation joint 109. After rough adjustment, the longitudinal pushers 104 and width pushers 106 can propel the AGV. Because the AGV is also subject to the abutment force of the longitudinal fixing block 105 and the width fixing block 111, the adjusted AGV is centered within the adjustment cavity. The provision of the bull's eye bearing 112 reduces friction between the tray and the frame 102 during rotation, reducing the labor intensity and burden on workers. Subsequently, the tray unlocking mechanism 3 releases the tray's longitudinal restraint on the battery module, allowing the length shaping mechanism 4 and the length reference clamping mechanism 5 to approach each other to the appropriate position, adjusting the battery module length.

[0060] In one embodiment, see Figure 3 The width reference clamping mechanism 2 includes a width reference side welding frame 201, a width direction pushing cylinder 202, a first guide rail 204, a first connecting seat 206 and a width pressing block 207. Among them, the width reference side welding frame 201 is fixedly connected to the frame 102. The width direction pushing cylinder 202 is installed on the width reference side welding frame 201. The first guide rail 204 is installed on the width reference side welding frame 201 along the width direction of the frame 102. The first connecting seat 206 is connected to the output end of the width direction pushing cylinder 202 and is slidably connected to the first guide rail 204. The width pressing block 207 is installed at one end of the connecting seat away from the width direction pushing cylinder 202 and is used to abut against the pallet. The first buffer 205 and the pressing in place switch 203 are installed on the width reference side welding frame 201, and the pressing in place switch 203 is used to control the width direction pushing cylinder 202 to pause.

[0061] It is understandable that multiple pallets are fixed on the AGV, each of which has a battery module, and multiple battery modules are distributed in columns. The width-direction pushing cylinder 202 drives the first connecting seat 206 to move along the first guide rail 204, thereby driving the width pressing block 207 to move closer to or away from the battery module on the pallet to perform a compacting operation on the multiple battery modules. This process can assemble multiple battery modules into one. During this process, the first buffer 205 can effectively absorb the impact force generated during compaction to prevent damage to the equipment. The compaction in place switch 203 sends a signal when the pressing block reaches the predetermined position, causing the width-direction pushing cylinder 202 to suspend operation, ensuring the accuracy and safety of the compacting operation, achieving precise compaction control of the pallet, and improving the working efficiency and safety of the equipment.

[0062] In one embodiment, see Figure 14 , the width clamping mechanism 8 includes a base plate seat 801, a width direction press 802, a sixth guide rail 803, a second connecting seat 804 and a width pressure strip 806. Among them, the base plate seat 801 and the width reference side welding frame 201 are respectively arranged on both sides of the width direction of the adjustment cavity. The width direction press 802 is installed on the base plate seat 801 through the press support 805. The sixth guide rail 803 is installed on the base plate seat 801 along the width direction of the frame 102. The second connection is connected to the output end of the width direction press 802 and is slidably connected to the fifth guide rail 613. The width pressure strip 806 is installed at the end of the second connecting seat 804 away from the width direction press 802 and is used to abut against the tray. It can be understood that the width reference clamping mechanism 2 and the width clamping mechanism 8 need to act simultaneously to clamp multiple battery modules, that is, the width direction pushing cylinder 202 and the width direction press 802 will move toward each other. When the width direction press 802 is started, the press will drive the width pressing strip 806 to move linearly along the sixth guide rail 803 on the base plate seat 801 through the second connecting seat 804 and the fifth guide rail 613, thereby clamping the multiple battery modules fixed on the tray in the width direction.

[0063] In one embodiment, see Figure 4The tray unlocking mechanism 3 includes a locking support 301, a second guide rail 308, a conveying cylinder 305, a sliding plate 310, a servo motor 302, a torque sensor 303 and a sleeve 307. Among them, the locking support 301 is installed on the frame 102. The second guide rail 308 is installed on the locking support 301 along the length direction of the frame 102. The conveying cylinder 305 is installed on the locking support 301. The sliding plate 310 is slidably connected to the second guide rail 308 and is connected to the output end of the conveying cylinder 305. The servo motor 302 is installed on the sliding plate 310. The torque sensor 303 is installed on the rotating shaft of the servo motor 302. The sleeve 307 is connected to the rotating shaft of the servo motor 302 through the torque sensor 303, and is used to release the length limit of the tray on the battery module. Its working principle and process are as follows: first, the locking support 301 is fixed on the frame 102 to provide stable support; secondly, the second guide rail 308 is installed on the locking support 301 along the length direction of the frame 102 to provide a track for the movement of the sliding plate 310; then, the conveying cylinder 305 is installed on the locking support 301, and its output end is connected to the sliding plate 310, and the sliding plate 310 is driven to move along the second guide rail 308 through the telescopic action of the cylinder; immediately afterwards, the servo motor 302 is installed on the sliding plate 310, driving the torque sensor 303 connected to it to rotate, and the torque sensor 303 applies torque through the connected sleeve 307 to release the length limit of the tray on the battery module; finally, the servo motor 302 accurately controls the rotation angle and output torque to unlock the tray, thereby releasing the limit on the length of the battery module, ensuring that the battery module can smoothly proceed to the next step of production and transportation process.

[0064] See also Figure 4 The tray unlocking mechanism 3 also includes an unlocking position switch 304, a bearing seat 306, an unlocking buffer 309, and a distance sensor 311. The unlocking position switch 304 and the distance sensor 311 are respectively mounted on the locking support 301. The unlocking position switch 304 is used to electrically connect to the sensing piece on the sliding plate 310. When the sensing piece is within the detection range of the unlocking position switch 304, the unlocking position switch 304 controls the conveying cylinder 305 to stop working. The distance sensor 311 is used to detect the distance between the tray unlocking mechanism 3 and the tray, thereby facilitating the control of the extension length of the conveying cylinder 305. The bearing seat 306 is mounted on the sliding plate 310. One end of the sleeve 307 is passed through the bearing seat 306, and the other end is connected to the torque sensor 303. The setting of the bearing seat 306 plays a supporting role for the sleeve 307.

[0065] In one embodiment, see Figures 5 to 8The length shaping mechanism 4 includes a shaping lifting assembly 410 and a length pressing assembly 420. The shaping lifting assembly 410 is mounted on the frame 102. The length pressing assembly 420 is connected to the shaping lifting assembly 410 and is used to abut against one end of the battery module in the longitudinal direction.

[0066] In one embodiment, see Figures 5 to 7 The shaping lifting assembly 410 includes a shaping lifting cylinder 4103, a third guide rail 4101, a push-end truss 4102, a second buffer 4104, a first positioning block 4105, a first slot switch 4106, a first latch detection switch 4107, a first connecting piece 4108 and a first safety pin 4109. The shaping lifting cylinder 4103 is installed on the frame 102, and the output end of the shaping lifting cylinder 4103 is connected to the push-end truss 4102. The third guide rail 4101 is installed on the frame 102, and the push-end truss 4102 is slidably connected to the third guide rail 4101. The first positioning block 410 5 is installed on the pushing end truss 4102, the first positioning block 4105 is provided with a first socket, the first connecting member 4108 is installed on the frame 102 and is provided with a groove and a second socket, the first positioning block 4105 is used to extend into the groove, the first safety pin 4109 is used to be inserted into the second socket and the first socket in sequence, the first latch detection switch 4107 and the first slot-shaped switch 4106 are respectively installed on the frame 102, the first slot-shaped switch 4106 is used to be electrically connected to the sensing piece on the pushing end truss 4102, and the second buffer 4104 is connected to the pushing end truss 4102 and is used to abut against the frame 102.

[0067] It is understandable that when the tray unlocking mechanism 3 releases the length limit of the battery module by the tray, the length shaping mechanism 4 and the length reference clamping mechanism 5 can work. The working principle of the shaping lifting assembly 410 is as follows: First, the shaping lifting cylinder 4103 drives the push-end truss 4102 to rise and fall vertically along the third guide rail 4101. Through the cooperation of the first positioning block 4105, the first connecting member 4108, the first safety pin 4109 and the second buffer 4104, the stability and accuracy of the push-end truss 4102 during the movement are ensured; secondly, the first pin detection switch 4107 and the first slot switch 4106 detect the position and movement state of the push-end truss 4102 in real time. Once a problem is found, the processing process can be stopped or adjusted in time to ensure product quality and operational safety.

[0068] In one embodiment, see Figure 8The length-compression assembly 420 includes a fixed base 4201, a length-compressing block 4206, and a length-direction press 4202, a length-guide rail 4203, a guide carriage 4204, and a diffuse reflection sensor 4205 on the fixed base 4201. The output end of the length-direction press 4202 is connected to the length-compressing block 4206, which is slidably connected to the length-guide rail 4203 and the guide carriage 4204. When the battery module needs to be compressed in the length direction, the length-direction press 4202 pushes the length-compressing block 4206 to move linearly along the length-guide rail 4203 and the guide carriage 4204 to a specified position. During this process, the diffuse reflection sensor 4205 monitors the position during the compression process, ensuring that the compression force is moderate and does not damage the workpiece, thereby ensuring that the workpiece remains stable during subsequent processing or testing, thereby improving processing accuracy and efficiency.

[0069] In one embodiment, see Figures 9 to 11 The length reference clamping mechanism 5 includes a length reference lifting assembly 510 and a tray fixed side wedging assembly 520 connected to the length reference lifting assembly 510. The tray fixed side wedging assembly 520 is used to abut one end of the battery module in the longitudinal direction. The length reference lifting assembly 510 includes a fourth guide rail 5101, a fixed side truss 5102, a reference lifting cylinder 5103, a clamping buffer 5104, a second positioning block 5105, a second slot switch 5106, a second latch detection switch 5107, a second connector 5108, and a second safety pin 5109. The operating principle of the length reference lifting assembly 510 is the same as that of the shaping lifting assembly 410, and the specific connection relationship between the various components is also the same as that of the shaping lifting assembly 410.

[0070] In one embodiment, see Figure 11 The wedging assembly 520 on the fixed side of the pallet includes a wedging support 5201, a wedge cylinder 5202, a fixed seat 5203, a pressure block cylinder 5204, a support shaft 5205 and a wedging pressure block 5206.

The top of the fixed seat 5203 is slidably connected to the bottom of the support, and the fixed seat 5203 is connected to the output end of the pressure block cylinder 5204. The fixed seat 5203 is sleeved on the outer periphery of the support shaft 5205 and is slidably connected to the support shaft 5205. The wedging pressure block 5206 is installed at the end of the support shaft 5205 close to the battery module. The wedge cylinder 5202 is used to extend into the fixed seat 5203 and to push the support shaft 5205 to drive the wedging pressure block 5206 close to the length direction of the battery module.

[0071] In one embodiment, see Figure 12 and Figure 13, the combined shaping equipment also includes a pole pressing assembly 6, the pole pressing assembly 6 includes a mounting seat 601, an electric cylinder 603, a guide shaft 606, a pressure sensor 607, a connecting frame 608, a centering cylinder 609, a fifth guide rail 613, a pole pressing plate 7, two skew detection switches 616 and two clamping supports 615, the mounting seat 601 is connected to the frame 102, the electric cylinder 603 is installed on the mounting seat 601 through the support beam 602, and the output end of the electric cylinder 603 is connected to the pressure sensor 607, the connecting frame 608 is connected to the pressure sensor 607, the guide shaft 606 is connected to the connecting frame 608, and is slidably connected to the support through the guide sleeve 605, the centering cylinder 609, the fifth guide rail 6 13 and one of the two clamping supports 615 are respectively connected to the connecting frame 608, the clamping support 615 is connected to the centering cylinder 609 through the clamping connecting seat 610, and the other clamping support 615 is slidably connected to the fifth guide rail 613 through the first mounting plate 614, and is connected to the output end of the centering cylinder 609. The inner sides of the two clamping supports 615 are both installed with clamping strips 617, which are used to abut against the two sides of the battery module. Two skew detection switches 616 are respectively connected to the two clamping supports 615 for detecting the horizontal tilt of the battery module. The pole clamping plate 7 is arranged between the two clamping supports 615 and is connected to the bottom of the connecting frame 608 through the guide block 618. The pole clamping assembly 6 here only acts on one battery module. Of course, in other embodiments, the pole clamping assembly 6 can act on each battery module in turn to ensure that each battery module can be located in the middle of each tray. After the pole pressing assembly 6 has completed its work, the width reference pressing mechanism 2 and the width clamping mechanism 8 will assemble and clamp the multiple battery modules into one.

[0072] The pole clamping assembly 6 also includes a proximity switch 604 mounted on the mounting base 601, upper and lower limiters 611 mounted on the connecting frame 608, and a third buffer 612. The proximity switch 604 is used to detect the sliding height of the guide shaft 606, facilitating the electric cylinder 603 to control the raising and lowering of the connecting frame 608. The upper and lower limiters 611 can control the raising and lowering height of the connecting base relative to the mounting base 601. The third buffer 612 is used to prevent the movable clamping support 615 from colliding with the connecting frame 608 during sliding.

[0073] The pole pressing plate 7 includes a second mounting plate 701 , a handle 702 mounted on the second mounting plate 701 , and a pressing strip 703 . The pressing strip 703 is used to press the pole on the battery module.

[0074] The working principle of the pole clamping assembly 6 is as follows: the electric cylinder 603 drives the connecting frame 608 downward, allowing the clamping strip 703 to abut and press the poles on the battery module, making the height of each pole on the battery module uniform and facilitating subsequent processes. Next, the centering cylinder 609 drives the clamping supports 615 closer together, so that the skew detection switch 616 on the clamping support 615 detects whether the battery module is in the middle of the corresponding tray. If it is in the middle, the clamping support 615 does not need to adjust the battery module; otherwise, the two clamping supports 615 will continue to move closer, allowing the battery module to rotate relative to each other, so that the battery module is located in the middle of the corresponding tray.
