Description

[0002] During cell assembly, structural adhesive is applied to the cell body, mounting end plate, and mounting side plate to improve the stability of the battery pack formed after cell assembly. Additionally, depending on the type of structural adhesive, heat dissipation of the cell can be achieved.

[0003] Structural adhesive, as a crucial component between the battery and the casing, significantly impacts the structural stability and thermal conductivity of the battery module.

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0028] Example 1, by Figure 1 , Figure 2 , Figure 3 and Figure 6The present invention provides a device for measuring the bonding area of ​​a battery module, comprising a movable adjustment mechanism 1, a position correction mechanism 2 fixedly disposed at the bottom end of the movable adjustment mechanism 1, a measuring mechanism 3 fixedly disposed at the bottom end of the position correction mechanism 2, the measuring mechanism 3 being located at the top of the battery cell conveyor belt, a cleaning tank 4 disposed on one side of the measuring mechanism 3, a transparent bonding plate 5 disposed inside the cleaning tank 4, and the measuring mechanism 3 comprising several booms 6, a transparent grid plate 7, a support frame 8, a first vision camera 9, a second vision camera 10, several limiting support components 11, and several suction components 12. The booms 6 are fixedly connected to the four corners at the bottom end of the position correction mechanism 2, the transparent grid plate 7 and the support frame 8 are both fixedly connected between the booms 6, the support frame 8 being located at the top of the transparent grid plate 7, the first vision camera 9 and the second vision camera 10 being fixedly connected to the two sides of the top end inside the support frame 8, the limiting support components 11 being fixedly connected to the bottom end of the side of the booms 6, and the suction components 12 being fixedly connected to the bottom end of the booms 6.

[0029] In use, after the battery cell dispensing is completed, the battery cell is transported by a battery cell conveyor belt. The movement pauses when the battery cell reaches the inspection station. At this time, the moving adjustment mechanism 1 moves the position correction mechanism 2 and the measuring mechanism 3 directly above the battery cell. Based on the battery cell's placement, the position correction mechanism 2 adjusts the height and angle of the measuring mechanism 3 to match the battery cell, ensuring the transparent mesh plate 7 overlaps with the battery cell. During normal inspection, no glue pressing operation is performed. The first vision camera 9 and the second vision camera 10 identify the number of meshes covering the dispensing area to determine if there are any defects in the dispensing location, as well as the length, width, and position of the dispensing. The device automatically identifies the glued area and determines the glued area by using the proportion of the grid occupied by the glued area. If the glued area matches the set area, the pressing area also matches the set area. During the inspection process, some battery cells are sampled for pressing to achieve accurate inspection. When pressing, the transparent pressing plate 5 inside the cleaning tank 4 is picked up by the suction component 12. The transparent pressing plate 5 presses the structural adhesive on the surface of the battery cell to spread the structural adhesive. Then, the pressing area can be inspected by the above steps. After the inspection is completed, the transparent pressing plate 5 is moved into the cleaning tank 4 by the measuring mechanism 3. The transparent pressing plate 5 is then cleaned by the cleaning tank 4.

[0030] Example 2, based on Example 1, is... Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7The limiting support assembly 11 includes a supporting beam 13, a limiting support sleeve 14, a lifting and adjusting support rod 15, a rubber buffer base 16, and a locking knob 17. The supporting beam 13 is fixedly connected to the side of the bottom end of the boom 6. The limiting support sleeve 14 is inserted through one end of the supporting beam 13 and fixedly connected to it. The lifting and adjusting support rod 15 is slidably inserted inside the limiting support sleeve 14. The locking knob 17 is connected to the side of the limiting support sleeve 14 and matches the lifting and adjusting support rod 15. The rubber buffer base 16 is fixedly connected to the bottom end of the lifting and adjusting support rod 15. A suction assembly is also included. 12 consists of an air guide tube 18, a hose 19, a rubber buffer sleeve 20, a flexible suction cup 21, a sealing ring 22, and a suction pump 23. The suction pump 23 is fixedly connected to the bottom end inside the position correction mechanism 2. The air guide tube 18 is fixedly connected to the inside of the boom 6 and connected to the suction pump 23. The rubber buffer sleeve 20 is fixedly connected to the bottom end of the boom 6. The flexible suction cup 21 is fixedly connected to the bottom end of the rubber buffer sleeve 20. The sealing ring 22 is fixedly connected to the side of the bottom end of the flexible suction cup 21. The hose 19 is located inside the rubber buffer sleeve 20 and is fixedly connected between the air guide tube 18 and the flexible suction cup 21.

[0031] During testing, the limiting support assembly 11 contacts the top surface of the battery cell conveyor belt to achieve a limiting effect and prevent the measuring mechanism 3 from contacting the battery cell. The length of the limiting support assembly 11 is adjusted according to the thickness of different types of battery cells. During adjustment, the locking knob 17 is loosened and the lifting adjustment support rod 15 is moved. The rubber buffer base 16 provides a buffering effect. When the suction assembly 12 suctions the transparent pressure plate 5, the exhaust pump 23 is started. The air guide pipe 18, hose 19 and flexible suction cup 21 form a negative pressure, thereby suctioning the transparent pressure plate 5 and making the transparent pressure plate 5 move with the measuring mechanism 3, thus realizing the pressure operation.

[0032] Example 3, based on Example 1, is... Figure 1 and Figure 2 As shown, the movable adjustment mechanism 1 includes several guide rails 24, movable adjustment screws 25, a first servo motor 26, several movable sliding sleeves 27 and screw sleeves 28. The guide rails 24, movable adjustment screws 25 and the first servo motor 26 are all hoisting connection structures. The movable adjustment screws 25 are fixedly connected to the output shaft of the first servo motor 26. The movable sliding sleeves 27 and screw sleeves 28 are both fixedly connected to the top of the position correction mechanism 2. The movable sliding sleeves 27 are sleeved on the guide rails 24, and the screw sleeves 28 are sleeved on the movable adjustment screws 25.

[0033] When the moving adjustment mechanism 1 is working, the first servo motor 26 drives the moving adjustment screw 25 to rotate, the moving adjustment screw 25 drives the moving sliding sleeve 27 to move, the moving sliding sleeve 27 drives the position correction mechanism 2 to move, and in turn drives the measuring mechanism 3 to move.

[0034] Example 4, based on Example 1, is... Figures 1 to 5 The position correction mechanism 2 includes a top support plate 29, a bottom support plate 30, a flexible telescopic protective sleeve 31, and a lifting and rotating adjustment assembly 32. The top support plate 29 is fixedly connected to the bottom end of the movable sliding sleeve 27 and the lead screw sleeve 28. The bottom support plate 30 is located at the bottom of the top support plate 29 and is connected to the top support plate 29 through the lifting and rotating adjustment assembly 32. The flexible telescopic protective sleeve 31 is fixedly connected to the side of the bottom end of the top support plate 29 and is fitted onto the lifting and rotating adjustment assembly 32. The flexible telescopic protective sleeve 31 and the bottom support plate 30 have a fitted connection structure. The lifting and rotating adjustment assembly 32 includes a mounting frame 33, a rotating support sleeve 34, several telescopic limit rods 35, a second servo motor 36, a drive gear 37, an internal gear ring 38, a lifting screw sleeve 39, a lifting adjustment screw 40, a first helical gear 41, a third servo motor 42, and a second helical gear 43. The mounting frame 33 is fixedly connected to the bottom end of the top support plate 29, and the rotating support sleeve 34 is fitted onto the mounting frame 36. The bottom end of the outer surface of the frame 33 is rotatably connected to the mounting frame 33. The telescopic limit rod 35 is fixedly connected to the side of the bottom end of the rotating support sleeve 34. The bottom end of the telescopic limit rod 35 is fixedly connected to the support base plate 30. The second servo motor 36 is fixedly connected to one side of the top end inside the mounting frame 33. The drive gear 37 is located inside the rotating support sleeve 34 and is fixedly connected to the output shaft of the second servo motor 36. The internal gear ring 38 is fixedly connected to the top end inside the rotating support sleeve 34 and meshes with the drive gear 37. The lifting screw sleeve 39 is inserted through the support base plate 30 and rotatably connected to it. The lifting adjustment screw 40 is inserted through the mounting frame 33 and the lifting screw sleeve 39 and rotatably connected to the mounting frame 33. The first helical gear 41 is fixedly connected to the top end of the lifting adjustment screw 40. The third servo motor 42 is fixedly connected to one side inside the mounting frame 33. The second helical gear 43 is fixedly connected to the output shaft of the third servo motor 42 and meshes with the first helical gear 41.

[0035] When the position correction mechanism 2 is working, the lifting and rotating adjustment component 32 is covered by the flexible telescopic protective sleeve 31 to prevent dust from entering. Since the bottom end of the flexible telescopic protective sleeve 31 is in contact with the support base plate 30, it will not affect the rotational movement. The second servo motor 36 drives the drive gear 37 to rotate, the drive gear 37 drives the internal gear ring 38 to rotate, the internal gear ring 38 drives the rotating support sleeve 34 to rotate, the rotating support sleeve 34 drives the telescopic limit rod 35 to rotate, and the telescopic limit rod 35 drives the support base plate 30 to rotate. The third servo motor 42 drives the second helical gear 43 to rotate, the second helical gear 43 drives the first helical gear 41 to rotate, the first helical gear 41 drives the lifting adjustment screw 40 to rotate, and the lifting adjustment screw 40 drives the lifting screw sleeve 39 to perform lifting and lowering operations. Since the lifting screw sleeve 39 is rotatably connected to the support base plate 30 and the telescopic limit rod 35 is a telescopic structure, it can drive the support base plate 30 to perform rotational and lifting adjustments simultaneously, improving the speed of adjustment.

[0036] Example 5, based on Example 4, by Figures 1 to 5 As shown, the rotating support sleeve 34 and the lifting adjustment screw 40 are rotatably connected to the mounting frame 33, and the lifting screw sleeve 39 is rotatably connected to the support base plate 30 via bearings. Several limiting guide arms 44 that are slidably limited and connected to the lifting screw sleeve 39 are fixedly provided on the side of the bottom end of the mounting frame 33. The top end of the lifting screw sleeve 39 is fixedly provided with a fall prevention limiting plate 45 that matches the limiting guide arm 44.

The second limiting support plate 48 is connected to the support top plate 29 via several second steel balls 49.

[0037] The bearings improve the mobility of the connection between the rotating support sleeve 34 and the lifting adjustment screw 40 and the mounting bracket 33, as well as the mobility of the connection between the lifting screw sleeve 39 and the support base plate 30. The limiting guide arm 44 can vertically limit the lifting screw sleeve 39 to prevent it from rotating with the lifting adjustment screw 40. The anti-fall limiting plate 45 can limit the lifting screw sleeve 39 to prevent it from falling off. The first limiting support plate 46 and the first steel ball 47 can provide auxiliary support for the support base plate 30, improving the stability of the installation while ensuring mobility. The second limiting support plate 48 and the second steel ball 49 can limit the lifting adjustment screw 40, improving its stability and mobility.

[0038] In operation, a measuring mechanism consisting of several booms, a transparent mesh plate, a support frame, a first vision camera, a second vision camera, several limiting support components, and several suction components can be set up. The transparent mesh plate divides the dispensing and pressing areas into multiple regions. The first and second vision cameras identify the areas occupied by the dispensing and pressing. The percentage of the pressing area relative to the cell area is measured using the number of meshes covered by structural adhesive, thus calculating the pressing area and improving the accuracy and efficiency of the measurement. The transparent pressing plate allows for sampling pressing operations on the cell, and the included cleaning tank facilitates cleaning of the transparent pressing plate. The device is designed for rinsing. A limit support assembly allows for height adjustment, limiting the measurement distance and improving safety. A suction assembly allows for the suction of the transparent adhesive plate. A moving adjustment mechanism, consisting of several guide rails, a moving adjustment screw, a first servo motor, several moving sleeves, and a screw sleeve, enables lateral movement of the entire measuring mechanism, allowing for position adjustment. A position correction mechanism, consisting of a top support plate, a bottom support plate, a flexible telescopic protective sleeve, and a lifting and rotating adjustment assembly, allows for both lifting and rotating adjustments of the measuring mechanism, thus adapting to adhesive testing of battery cells in different placement positions.
