From the initial optimization of battery life by increasing the power, they gradually began to focus on improving the overall efficiency by reducing the external cold and heat load through thermal insulation design. The current battery structure uses thermal insulation cotton on the top and sides of the module to reduce the heat transfer parameters for insulation.

[0003] At present, the heat transfer parameters are reduced by spraying polyurethane foam insulation coating (colloidal) on specific parts of the battery box for insulation, such as Figure 1 As shown, the battery box is transmitted to the bottom of the gantry by a transmission device, and the operator transmits the masking tool to the top of the battery box for masking, and then the polyurethane foam thermal insulation paint is sprayed through the spraying device on the gantry. After spraying, the polyurethane foam thermal insulation paint can be sprayed to the specific position of the battery box through the holes set at the specific position on the masking tool. However, with the above-mentioned spraying method, after the masking tool masks one or several groups of battery boxes, the masking tool needs to be removed and the polyurethane foam thermal insulation paint on the masking tool needs to be cleared and then sent to the gantry position for masking, which will cause too long operation downtime and affect the spraying efficiency of the thermal insulation layer of the battery box.

[0040] See also Figure 3-6 In the above, the driving assembly specifically includes a motor 11 and a driving rod 12. The motor 11 is arranged on an outer wall of one side of the base frame 4. One end of the driving rod 12 is fixed to the output end of the motor 11, and the other end passes through the long plate 7 and forms a rotation connection with the long plate 7. A bidirectional thread groove 13 is provided on the outer wall of the driving rod 12. A first guide shaft 14 that forms a sliding fit with the bidirectional thread groove 13 is provided at the long plate 7 where the driving rod 12 passes through.

The two drive rods 12 are connected by a transmission toothed belt 15. When the motor 11 drives one drive rod 12 to rotate, the other drive rod 12 rotates with the transmission toothed belt 15. The outer walls of the two drive rods 12 are provided with tooth grooves that mesh with the transmission toothed belt 15 to ensure that the two drive rods 12 rotate synchronously. A transmission cavity 46 is provided in the base frame 4. The transmission toothed belt 15 spans the transmission cavity 46 to connect the two drive rods 12. The two-way thread grooves 13 on the two drive rods 12 are connected to the first guide shafts 14 on the two long plates 7 (see FIG. 1 ). Fig. 9 ) can make the transmission of the two sets of shielding tooling 6 more stable, wherein the transmission cavity 46 will not interfere with the pull-out box 10.

[0041] See also Figure 3 , 4Each time the glue spraying device 3 sprays glue, it is sprayed on the battery box through the opening area 16 of the shielding tooling 6. In order to ensure the glue cleaning operation at the opening area 16 of the shielding tooling 6, the cleaning component includes a pressing plate 17 and a plurality of convex plates 18 arranged at the bottom of the pressing plate 17. The convex plates 18 are arranged on the pressing plate 17 corresponding to the opening areas 16 on the shielding tooling 6. The pressing plate 17 is slid up and down in the glue cleaning area 8. A pressing component for driving the pressing plate 17 to move up and down is provided in the glue cleaning area 8. When the shielding tooling 6 is completely located in the glue cleaning area 8, the pressing component can drive the convex plate 18 to be reciprocatedly inserted into the opening area 16 of the shielding tooling 6, thereby cleaning the colloid in the opening area 16 of the shielding tooling 6.

[0042] See also Figure 3 , 4 , 7, 8. Specifically, the pressing assembly includes a disc 19 and a convex portion 20. The convex portion 20 is radially slidably arranged on the disc 19. Since the cleaning areas 8 on both sides of the base of the conveying device 1 need to perform cleaning operations of the shielding tooling 6, the disc 19 is coaxially arranged at both ends of the axial direction of the driving rod 12. Side extension plates 21 extend outwardly on both sides of the top of the pressure plate 17. The bottom of the side extension plate 21 is connected to an L-shaped plate 22. The bottom end of the L-shaped plate 22 extends to a position directly below the disc 19. A side extension groove 23 for the side extension plate 21 to slide up and down is provided on the side wall of the cleaning area 8. The inner wall of the bottom of the side extension groove 23 is provided with a second spring 24 that drives the side extension plate 21 to move upward. The disc 19 is provided with a linkage member that causes the convex portion 20 to slide out of the disc 19 when the shielding tooling 6 enters directly below the pressure plate 17. The convex portion 20 is located on the disc 19 when the shielding tooling 6 has not completely entered the cleaning area 8. When the shielding tool 6 completely enters the cleaning area 8, the convex portion 20 partially slides out of the disc 19. When the disc 19 rotates, the convex portion 20 will squeeze the L-shaped plate 22 to move the pressure plate 17 downward, and the second spring 24 will drive the side extension plate 21 to move upward, thereby realizing the up and down movement of the pressure plate 17, so that the convex plate 18 is inserted into the opening area 16 of the shielding tool 6 to realize cleaning. It should be noted that: the side extension plate 21 is combined with the L-shaped plate 22 to bypass the driving rod 12 and make the bottom end of the L-shaped plate 22 directly under the disc 19. In addition, the side extension plate 21 will not interfere with the long plate 7. In addition, the side of the side extension groove 23 in the base frame 4 is also connected with an L-shaped groove 49 for the L-shaped plate 22 to move up and down, so that the L-shaped plate 22 can move up and down.

[0043] Reference Figure 4 , 78. Specifically, the linkage member includes a push rod 48, a convex groove 25 for the convex portion 20 to slide is radially provided on the disc body 19, a push rod groove 26 for the push rod 48 to slide is axially provided on the disc body 19, the push rod groove 26 is connected to the convex groove 25, a first inclined surface is provided on one side of the convex portion 20, a second inclined surface is provided on one side of the push rod 48 to abut against the first inclined surface, and a first spring 27 is provided at the bottom of the convex groove 25 to drive the convex portion 20 to move toward the radial inner end of the disc body 19. After the shielding tooling 6 moves to the clearing area 8 The end of the long plate 7 will abut against the push rod 48, and the push rod 48 slides and drives the protrusion 20 to slide outward through the cooperation of the first inclined surface and the second inclined surface. When the shielding tooling 6 moves out of the clear glue area 8, the first spring 27 pulls the protrusion 20 down to the inside of the disk body 19 and drives the push rod 48 to move outward to the initial position, wherein the push rod 48 maintains an interference fit with the push rod groove 26 and will not slide and detach from the push rod groove 26 when no force is applied. A rotating area 28 for the disk body 19 and the protrusion 20 to rotate is provided in the base frame 4.

[0044] See also Figure 2 , 5 8. In order to make the shielding tooling 6 located directly above the battery box for shielding, another set of shielding tooling 6 is located in the glue cleaning area 8 for glue cleaning. The driving rod 12 includes a main rod 121 and a sleeve rod 122. The sleeve rod 122 is rotatably sleeved on the main rod 121. A ratchet and pawl mechanism is provided between the sleeve rod 122 and the main rod 121. The ratchet and pawl mechanism includes a pawl 50 provided on the main rod 121 and a ratchet groove 29 provided at the end of the sleeve rod 122. When the motor 11 rotates forward, the pawl 50 can be stuck in the ratchet groove 29 and drive the sleeve rod 122 to rotate. At this time, it can be driven By moving the two groups of shielding tools 6 to slide on the base frame 4, one group of shielding tools 6 can be located above the battery box for shielding operations. When the motor 11 reverses, the relative sliding of the pawl 50 and the ratchet groove 29 will not drive the sleeve rod 122 to rotate. At this time, the disk body 19 rotates with the main rod 121, so that the convex portion 20 continues to press down the L-shaped plate 22, so that the convex plate 18 under the pressure plate 17 continues to perform glue cleaning operations on the shielding tools 6 in the glue cleaning area 8, so that when the glue spraying device 3 is spraying glue, the shielding tools 6 located in the glue cleaning area 8 are subjected to glue cleaning operations, thereby greatly reducing the operation connection time.

[0045] See also Figure 3 , 9In order to make the shielding tooling 6 better shield the battery box, base blocks 30 are provided at both ends of the long board 7 in the length direction. The base block 30 includes a fixed block 301 and a movable block 302. A plug rod 31 is provided on the top of the movable block 302, and a slot for inserting the plug rod 31 is provided at the bottom of the top block. The movable block 302 is slid up and down under the fixed block 301 through the cooperation of the plug rod 31 and the slot. The shielding tooling 6 is fixed on the fixed block 301, and a guide wheel 47 is provided on the outer side of the movable block 302 for rotation. The base frame 4 is provided with a guide wheel 47 on the inner walls of both sides of the glue spraying area 5. The horizontal guide wheel groove 32 and the V-shaped guide wheel groove 33, wherein the horizontal guide wheel groove 32 extends to the inside of the glue cleaning area 8 at one end away from the V-shaped guide wheel groove 33, and the horizontal guide wheel groove 32 is connected to both sides of the V-shaped guide wheel groove 33. When the guide wheel 47 is located at the bottom of the V-shaped guide wheel groove 33, the shielding tooling 6 is just located above the battery box. The shielding tooling 6 can slide downward through the cooperation of the guide wheel 47 and the V-shaped guide wheel groove 33 and approach the battery box, thereby reducing the gap between the shielding tooling 6 and the top of the battery box and improving the spraying position of the polyurethane foam thermal insulation coating.

[0046] See also Figure 3 , 9 10. In order to remove the colloid from the surface of the shielding tooling 6, a scraper plate 34 is provided on the top of the shielding tooling 6. The bottom end surface of the scraper plate 34 is fitted with the shielding tooling 6. Slide blocks 35 are symmetrically provided on both sides of the scraper plate 34. Slide grooves 36 for the slide blocks 35 to slide are symmetrically provided on both sides of the shielding tooling 6. The bottom of the slide groove 36 passes through the shielding tooling 6 and has a certain distance from the opening area 16 of the shielding tooling 6, so as to ensure that the colloid will not gather in the slide groove 36 and prevent the colloid from being sprayed down from the slide groove 36. A rotating rod 37 is rotatably provided in the slide groove 36. The slider 35 is sleeved on the rotating rod 37 and is threadedly connected with the rotating rod 37. A hollow groove 38 is provided in the middle of the rotating rod 37. A spiral guide groove 39 is provided inside the hollow groove 38.

When the shielding tooling 6 slides toward the glue cleaning area 8, the docking rod 41 will be inserted into the hollow interior of the rotating rod 37, and the rotating rod 37 will rotate under the cooperation of the second guide shaft 42 and the spiral guide groove 39 to drive the slider 35 to slide, thereby causing the scraper plate 34 to slide and clean the glue on the surface of the shielding tooling 6. It should be noted that: in the initial state, the scraper plates 34 on the two groups of shielding tooling 6 are arranged on the side away from each other. When the shielding tooling 6 enters the glue cleaning area 8, the scraper plates 34 can first move from the inner end of the glue cleaning area 8 to the outer end.

[0047] The present invention provides a second embodiment:

[0048] The difference between this embodiment and the first embodiment is that:

[0049] See also Figure 3 , 4 , 11, 12, racks 45 are provided on the inner walls of both sides of the glue spraying area 5, and two sets of racks 45 are provided on the inner walls of each side and are symmetrically arranged on both sides of the V-shaped guide wheel groove 33.

A gear 44 is provided on the short shafts 43. The shielding tooling 6 slides from the glue spraying area 5 to During the process in the glue cleaning area 8, the gear 44 and the rack 45 complete a meshing to make the shielding tool 6 flip 180°. After the shielding tool 6 flips 180°, the hollow interior of the rotating rod 37 is opposite to the docking rod 41. Since the shielding tool 6 will flip 180° before entering the glue cleaning area 8, in the initial state, the opening of the hollow groove 38 and the shaft opening 40 will be set on the side where the two groups of shielding tools 6 are close to each other. After the shielding tool 6 flips 180°, the hollow groove 38 will be opposite to the docking rod 41.

[0052] Step 2: spray glue on the shielding tool 6 through the glue spraying device 3, so that the thermal insulation paint is sprayed from the opening area 16 of the shielding tool 6 to the battery box;

[0053] Step three, the conveying device 1 moves the next group of battery boxes to the bottom of the glue spraying device 3, and the driving motor 11 rotates forward, so that the masking tool 6 located in the glue spraying area 5 slides into the glue cleaning area 8 and is located directly above the battery box, and the masking tool 6 previously located in the glue cleaning area 8 is moved to the position of the glue spraying area 5, and the driving motor 11 is reversed to allow the cleaning component to clean the colloid on the masking tool 6. At the same time, the glue spraying device 3 sprays the thermal insulation coating on the battery box through the opening area 16 of the masking tool 6, completing a cyclic alternating operation of spraying the battery box and cleaning the masking tool 6.

[0054] See also Figure 1-12When the device is in use, the battery box is conveyed to the bottom of the glue spraying device 3 of the gantry 2 through the conveying device 1. At this time, the output end of the motor 11 rotates forward to drive the main rod 121 to rotate forward. The main rod 121 rotates forward and drives the sleeve rod 122 to rotate forward through the ratchet pawl mechanism, thereby driving the two groups of shielding tools 6 to move until one group of shielding tools 6 is located directly above the battery box. At this time, under the cooperation of the guide wheel 47 and the V-shaped guide wheel groove 33, the moving block 302 moves toward the bottom of the fixed block 301 and drives the shielding tool 6 to move downward, so that the shielding tool 6 is closer to the battery box. At this time, the glue spraying operation can be carried out through the glue spraying device 3, and a group of battery boxes After the glue spraying is completed, the next group of battery boxes are moved to the bottom of the glue spraying device 3 by the conveying device 1 and the motor 11 is driven to continue to rotate forward, so that the shielding tooling 6 in the glue cleaning area 8 is moved to the top of the battery box, and the shielding tooling 6 previously located above the battery box is moved into the glue cleaning area 8. In the process of the shielding tooling 6 moving into the glue cleaning area 8, the gear 44 on one side of the short shaft 43 will mesh with the rack 45 once, so that the shielding tooling 6 is turned 180 degrees, so that the hollow groove 38 of the rotating rod 37 is aligned with the docking rod 41. In the process of the shielding tooling 6 continuing to slide into the glue cleaning area 8, the second guide shaft 42 on the docking rod 41 will engage with the spiral The guide groove 39 cooperates with and drives the rotating rod 37 to rotate. The rotation of the rotating rod 37 will drive the scraper plate 34 on the shielding tooling 6 to slide and scrape the colloid on the surface of the shielding tooling 6. When the shielding tooling 6 completely enters the clearing area 8, the fixed block 301 will abut against the push rod 48 and drive the push rod 48 to slide. The push rod 48 slides and moves out of the disc 19 with one end of the protrusion 20, and the motor 11 can be driven to reverse. Under the action of the ratchet pawl mechanism, the sleeve rod 122 will not rotate, so that the two sets of shielding tools 6 will not move, and the disc 19 will continue to rotate. The rotation of the disc 19 causes the protrusion 20 to rotate continuously and squeeze the L-shaped plate 22. In cooperation with the second spring 24, the pressure plate 17 continues to move up and down, so that the convex plate 18 continues to clean the glue in the opening area 16 on the shielding tooling 6, and the scraped colloid will fall into the pull-out box 10 for collection. After the battery spraying is completed, when the shielding tooling 6 slides out of the glue cleaning area 8, the second guide shaft 42 cooperates with the spiral guide groove 39 to reverse the sleeve rod 122, so that the scraper plate 34 returns to its initial position. After that, when the shielding tooling 6 that has cleaned the colloid moves to the top of the next group of battery boxes, the other group of shielding tooling 6 will move to the glue cleaning area 8 to clean the glue, completing the alternating operation.
