Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] See Figure 1 A battery module tray flipping and gluing inspection device includes a three-axis gluing mechanism 1, a battery module tray gripping and flipping mechanism 2, and an inspection gluing mechanism 3. The tray gripping and flipping mechanism 2 includes a lifting mechanism 21, a flipping mechanism 22, and a battery module tray gripping mechanism 23. The battery module tray gripping mechanism 23 includes a pressing unit 231, a side pocket unit 232, and a pin unit 233. The pressing unit 231 includes a pressure plate 2311 and a first driving device for driving the pressure plate 2311 to press down and lift. The side pocket unit 232 includes a side pressure plate 2321 and a second driving device for driving the side pressure plate 2321 to move back and forth. The pin unit 233 includes a plurality of pins 2331 that engage with the battery module tray and a third driving device for driving the pins to extend and retract. The flipping mechanism 22 drives the battery module tray gripping mechanism 23 to rotate, and the lifting mechanism 21 drives the flipping mechanism 22 and the battery module tray gripping mechanism 23 to move up and down. When the pin engages with the battery module tray, the pressure plate 2311 and the side pressure plate 2321 press the battery module together, thereby enabling the battery module tray to be gripped.

[0021] Among them, the glue-applying detection mechanism 3 is arranged on the rear side of the conveyor line. After the glue is applied and the curing is completed, the tray flipping mechanism 2 drives the battery module tray to the corresponding detection position, and after the detection is completed, it returns to its original position and puts the tray back on the conveyor line.

[0022] like Figures 1 to 6 As shown, this embodiment of the invention provides a battery module tray flipping and gluing inspection device, including a three-axis gluing mechanism 1, a battery module tray gripping and flipping mechanism 2, and an inspection and gluing mechanism 3. The three work together to realize the automated flipping, gluing, and inspection of battery modules.

[0023] 1. Battery module tray gripping and flipping mechanism See Figures 2-5 The battery module tray gripping and flipping mechanism 2 includes a lifting mechanism 21, a flipping mechanism 22, and a battery module tray gripping mechanism 23, which are used to realize the gripping, lifting, and flipping actions of the battery module tray, providing a suitable angle and position for the glue application operation.

[0024] 1.1 Lifting Mechanism See Figure 2 and Figure 5 The lifting mechanism 21 includes a pair of electric cylinders 211 arranged symmetrically on the left and right. The moving ends of the pair of electric cylinders 211 are fixedly connected to the fixed plate 221 of the flipping mechanism 22. The extension and retraction of the electric cylinders 211 drives the fixed plate 221, the flipping mechanism 22 installed on the fixed plate 221, and the battery module tray gripping mechanism 23 to move up and down as a whole, thereby realizing the lifting action of the tray.

[0025] Preferably, this application uses a guide rail electric cylinder, which cooperates with a guide rail and a slider. The slider is fixedly connected to the fixed plate 221. When the guide rail electric cylinder works, the slider can move up and down along the guide rail, thereby driving the fixed plate 221 to move up and down.

[0026] Electric cylinder drive has the advantages of high positioning accuracy and smooth operation. When combined with guide rail 212 and slot light sensor, it can further improve the accuracy and reliability of lifting action.

[0027] 1.2 Tilting Mechanism See Figure 2 and Figure 5The flipping mechanism 22 includes a pair of fixed plates 221 symmetrically arranged on the left and right, a pair of servo motors 222, and a pair of connecting plates 223. The servo motors 222 on the same side are fixed to the fixed plates 221 on the same side. The output end of the servo motor 222 passes through the fixed plates 221 and is fixedly connected to the connecting plates 223. The rotation shaft of the servo motor 222 is fixedly connected to the connecting plates 223, driving the connecting plates 223 and the battery module tray gripping mechanism 23 mounted on the connecting plates 223 to rotate. The servo motors 222, in conjunction with a reducer and a slot light sensor 6, can achieve precise flipping within the range of 0°-120° (actually, it can rotate 360°, but this invention specifically uses 0°-120° in use), ensuring the consistency of the adhesive application angle and meeting the requirements of different adhesive application processes.

[0028] 1.3 Battery module tray gripping mechanism See Figures 2-4 The battery module tray gripping mechanism 23 includes a pressing unit 231, a side pocket unit 232, and a pin unit 233. The three work together to achieve a stable gripping of the battery module and prevent the module from being thrown out during the flipping process.

[0029] See Figure 3 The pressing unit 231 includes a pressing plate 2311 and a first driving device for pressing down and lifting the pressing plate 2311. The first driving device includes a pair of rodless cylinders 2312 symmetrically arranged on the left and right sides. A first sliding block is slidably connected to each rodless cylinder 2312. The left and right ends of the pressing plate 2311 are respectively fixed to the sliding ends of the pair of rodless cylinders 2312. The pressing plate 2311 is driven to move up and down by the first rodless cylinders 2312, thereby pressing down and fixing the battery module. The pressing plate 2311 is equipped with a positioning detection photoelectric sensor 5 to detect whether the pressing plate 2311 is pressing the battery module firmly, ensuring reliable fixing.

[0030] See Figure 4 The side-holding unit 232 includes a side pressure plate 2321 and a second driving device for moving the side pressure plate 2321 back and forth. The second driving device includes a pair of first guide rod cylinders 2322 symmetrically arranged on the left and right sides. The left and right sides of the side pressure plate 2321 are respectively fixed to the telescopic ends of the pair of first guide rod cylinders 2322. By driving the side pressure plate 2321 back and forth through the first guide rod cylinders 2322, bottom support for the side of the battery module is achieved. The side pressure plate 2321 is equipped with a positioning detection photoelectric sensor 5, used to detect whether the side pressure plate 2321 holds the battery module, improving the stability of the gripping process.

[0031] See Figure 5The pin unit 233 includes several pins 2331 that engage with the battery module tray and a third driving device for extending and retracting the pins 2331. The third driving device includes a pair of symmetrically arranged second guide rod cylinders 2332, and the pins 2331 are fixedly connected to the extension and retraction ends of the first guide rod cylinders 2322. By driving the pins 2331 to extend and retract through the second guide rod cylinders 2332, engagement and positioning with the battery module tray are achieved, further preventing tray displacement during flipping.

[0032] 2. Triaxial glue application mechanism See Figure 6 The three-axis adhesive application mechanism 1 includes a three-axis frame 11, on which a pair of adhesive application components 12 are fixed for precise adhesive application to the battery module. The three-axis frame 11 adopts a sliding form with gears, racks, and slide rails, driven by a servo motor and equipped with closed-loop feedback of magnetic scale position to ensure precise control of the adhesive application trajectory.

[0033] See Figure 7 The adhesive application assembly 12 includes a three-axis connecting plate 121 fixedly connected to the moving end of the three-axis frame 11, an adhesive application head 122 fixed on the three-axis connecting plate 121, a second rodless cylinder 123 that drives the adhesive application head 122 to move up and down, a distance measuring and positioning assembly 124, and an adhesive receiving assembly 125.

[0034] Glue applicator 122: Used to evenly apply glue to designated positions on the battery module. The second rodless cylinder 123 drives the glue applicator 122 to move up and down. The position of the glue applicator 122 can be adjusted according to the height of the module to adapt to modules of different sizes.

[0035] Distance measuring and positioning component 124: Used for distance measuring and positioning before adhesive application, ensuring that the distance between the adhesive application head 122 and the module surface meets the process requirements, thus improving adhesive application accuracy. The distance measuring and positioning component 124 is rotatable to ensure that the angle with the module and the adhesive application angle are consistent, further improving the adhesive application effect. Preferably, it specifically includes an industrial camera and a rangefinder; the industrial camera performs visual positioning and photography, and the rangefinder performs distance measurement.

[0036] In this embodiment, the industrial camera is model MV-CU050-30GMGC, and the rangefinder is model WTM10L-241611D0A00ZVZZZZZZZZZ. The adhesive receiving assembly 125 includes a lifting cylinder 1251 fixed on a three-axis connecting plate 121, a motor 1252 fixedly connected to the moving end of the lifting cylinder 1251, a connecting block 1253 fixedly connected to the output end of the motor 1252, and an adhesive receiving box 1254 fixedly connected to the front end of the connecting block 1253. After the adhesive is applied, the lifting cylinder 1251 drives the adhesive receiving box 1254 to move to a position slightly below the horizontal line of the adhesive application head 122, and the motor 1252 drives the adhesive receiving box 1254 to rotate below the adhesive application head 122 to catch the adhesive dripping from the adhesive application head 122, thus preventing adhesive from contaminating the equipment and production environment, and reducing material waste.

[0037] During the glue application process, the glue receiving assembly 125 is in a reset standby state, and the glue receiving box 1254 is located away from below the glue application head 122 to avoid interfering with the glue application action. After the glue application is completed, the lifting cylinder 1251 drives the glue receiving box 1254 to move upward, and at the same time, the motor drives the glue receiving box 1254 to rotate directly below the glue application head 122 to catch the remaining glue dripping from the glue application head 122. When the tray flipping mechanism 2 drives the module to return to its original position and the glue application assembly is ready to reset, the motor 1252 rotates in the opposite direction to drive the glue receiving box 1254 away from below the glue application head 122, and the lifting cylinder 1251 drives the glue receiving box 1254 to descend to the initial standby position, completing one glue application cycle.

[0038] 3. Testing the glue application mechanism See Figure 8 The detection and coating mechanism 3 includes a pair of brackets 31, a single-axis module 32 fixedly connected to the pair of brackets 31, and a detection component 33 fixedly connected to the moving end of the single-axis module 32, which is used to detect the battery module after coating to ensure the coating quality.

[0039] See Figure 9 The detection component 33 includes a single-axis module connecting plate 331, an area array camera 332 disposed at the front end of the single-axis module connecting plate 331, a fourth driving device 333 fixed at the lower end of the single-axis module connecting plate 331, and a ranging component 334 fixed at the front end of the single-axis module connecting plate 331.

[0040] In this embodiment, the area scan camera is model MV-CH120-20GMGC.

[0041] Area scan camera 332: Used to capture images of the module surface after adhesive application, and to analyze the images to determine whether the adhesive application is uniform, whether there are any omissions, or repeated applications of adhesive.

[0042] Distance measuring component 334: Specifically, a distance measuring instrument is used to detect the position and size of the insulating sheet to ensure that the insulating sheet is installed in accordance with the requirements.

[0043] The fourth driving device 333 is used to drive the area scan camera 332 to move back and forth, adapting to the detection of modules of different sizes. The fourth driving device 333 includes a lead screw mounting base 3331 fixed to the lower end of the single-axis module connecting plate 331, a lead screw 3332 passing through the lead screw mounting base 3331, a lead screw nut 3333 threadedly installed on the lead screw 3332, a camera connecting plate 3334 fixedly connected to the lead screw nut 3333, and a handwheel 3335 fixedly connected to one end of the lead screw 3332. The area scan camera 332 is fixedly connected to the camera connecting plate 3334. By rotating the handwheel 3335, the lead screw 3332 is rotated, thereby driving the camera connecting plate 3334 and the area scan camera 332 to move back and forth, adjusting the detection position. It also features hard limit switches to facilitate adjustment of the module's compatibility width, adapting to the detection needs of different blueprint modules.

[0044] 4. Work Process A method for using a battery module tray flipping and adhesive coating inspection device, namely the working process of the battery module tray flipping and adhesive coating inspection device of the present invention, is as follows: The battery module tray (used to load battery modules) is transported to the designated position via the conveyor line 4, and the lifting and positioning mechanism 41 lifts and positions the tray. The conveyor line 4 is equipped with a commonly available lifting and positioning mechanism 41, see Figure 1 This mechanism typically consists of a cylinder, a guide shaft, a positioning block, and a detection sensor. During operation, the cylinder drives the lifting platform to rise, and together with the positioning block, it achieves precise positioning and stable support for the battery module tray. After lifting, it can stably support the weight of the tray and the module, meeting the positioning requirements for subsequent gripping, flipping, and gluing operations. Its structure is mature and highly reliable, and it is widely used in material positioning scenarios on automated production lines.

[0045] The lifting mechanism 21 drives the tilting mechanism 22 to descend, and the second guide rod cylinder 2332 of the pin unit 233 drives the pin 2331 to extend and engage with the tray for positioning. The first rodless cylinder 2312 of the pressing unit 231 drives the pressure plate 2311 to press down and hold the battery module, and the positioning detection photoelectric 5 detects the positioning; the first guide rod cylinder 2322 of the side pocket unit 232 drives the side pressure plate 2321 to extend and hold the side of the battery module, and the positioning detection photoelectric 5 detects the positioning. The lifting mechanism 21 drives the flipping mechanism 22 to rise, and the servo motor 222 of the flipping mechanism 22 drives the battery module tray gripping mechanism 23 to rotate to the set glue application angle. The three-axis frame 11 of the three-axis glue coating mechanism 1 drives the glue coating component 12 to move to the detection position. After the ranging and positioning component 124 performs ranging and positioning, the glue coating head 122 performs glue coating on the battery module. The second rodless cylinder 123 adjusts the position of the glue coating head 122 according to the height of the battery module. After the adhesive is applied, the lifting cylinder 1251 and motor 1252 of the adhesive receiving assembly 125 drive the adhesive receiving box 1254 to move to the area below the adhesive application head 122 to receive the adhesive; at the same time, the flipping mechanism 22 drives the module to rotate at a certain angle and stand still for a period of time to ensure that the adhesive cures. After the adhesive has initially cured, the servo motor 222 of the flipping mechanism 22 starts in reverse, driving the battery module tray gripping mechanism 23 to rotate back to the initial state, ensuring that the battery module tray maintains its initial posture for easy subsequent placement. The electric cylinder 211 of the lifting mechanism 21 is activated, driving the tray flipping mechanism 22 to descend as a whole until the bottom of the battery module tray is in contact with the lifting and positioning mechanism 41 on the conveyor line, and the lifting and positioning mechanism 41 remains in a supporting state. First, the second guide rod cylinder 2332 of the pin unit 233 drives the pin 2331 to retract, releasing the engagement and positioning with the tray; then, the first guide rod cylinder 2322 of the side pocket unit 232 drives the side pressure plate 2321 to retract, releasing the bottom support on the side of the module; finally, the first rodless cylinder 2312 of the pressing unit 231 drives the pressure plate 2311 to lift, releasing the downward pressing and fixing of the module. The electric cylinder 211 of the lifting mechanism 21 continues to drive the tray flipping mechanism 22 to lift it upward a certain distance, so that the components of the tray flipping mechanism 23 are completely separated from the battery module tray to avoid interference. The lifting and positioning mechanism 41 descends, placing the battery module tray smoothly on the conveyor line. The conveyor line starts and transports the tray to the detection position corresponding to the detection and gluing mechanism 3 (because the detection and gluing mechanism 3 is behind the conveyor line, the conveyor line drives the tray to move backward to the detection area). The single-axis module 32 of the glue-applying mechanism 3 drives the detection component 33 to move to the detection position. The fourth drive device 333 adjusts the position of the area array camera 332. The area array camera 332 captures the glue-applying image. The ranging component 334 detects the insulating sheet and completes the glue-applying quality detection. After passing the inspection, the conveyor line continues to operate, transporting the battery module tray to the next process; if the inspection fails, the equipment issues an alarm (the area scan camera is connected to the back-end equipment, and when the area scan camera identifies a defect, it sends a signal to the back-end equipment, such as a computer, so that the monitoring personnel can receive the alarm information in time), the conveyor line stops, and the staff performs NG module repair.

[0046] In a preferred embodiment of the present invention, a pair of battery module tray gripping and flipping mechanisms 2 can be set on a conveyor line, which can grip and flip the trays of two lines at one time. The three-axis glue coating mechanism 1 covers the range of the two lines, realizing dual-station operation and greatly improving work efficiency.

[0047] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
