[0021] As another preferred embodiment, the lead-acid battery automatic assembly process is applied to a lead-acid battery automatic assembly equipment, comprising the following steps:

[0022] Step 1, glue injection step, fix the cover plate on the fixed plate by the mechanical arm, and inject glue as the circular conveyor moves to the bottom of the glue injection machine. After the glue injection machine injects a part of glue into the cover plate, the cover plate continues to move and enters the dust cover. At this time, one of the three fixed rods extends to tilt the fixed plate. At the same time, under the drive of the first rack, the fixed rod rotates, and then the fixed plate is tilted to the surroundings in turn under the action of the fixed rod, so that the glue in the cover plate tilts to the edge, and then the glue pre-wet the side wall of the cover plate. After completion, the cover plate continues to move and enters the supplementary part. The pressing plate moves down to hang down the excess glue remaining on the side wall to keep the glue as uniform as possible. Then, a second glue injection is performed to keep the glue in each place in the cover plate equal.

[0023] Step 2, the slicing step, the slicing step and the glue injection step are carried out simultaneously, the first conveyor belt and the second conveyor belt synchronously input the battery shell and the isolation sheet into the device, the isolation sheet enters the chute, when the battery shell passes under the chute, the battery shell lifts the baffle to open the sheet outlet, the isolation sheet in the chute falls accurately into the battery shell, the battery shell continues to move backward, passes through the adjusted component, the suction cup on the adjustment component moves downward under the action of the incomplete gear rod and presses the isolation sheet and then moves horizontally, pushing the isolation sheet to the middle partition of the battery shell, so that the isolation sheets used are all fitted to the middle partition of the battery shell, and the placement of the isolation sheet is completed;

[0024] Step three, the assembly step, the cover plate with the completed corner assembly is moved to the bottom of the assembly component, and the moving component flips the battery shell and moves it to the top of the assembly component. The assembly component moves up to a horizontal position with the lower part of the battery shell. At this time, the cover plate moves up, and the cover plate first contacts the assembly component during the moving process, causing the seesaw to rotate, and the seesaw extends into the middle of the cover plate, pushing the glue in the cover plate to the outside, and the cover plate continues to move up so that the cover plate contacts the battery shell, and then the assembly component moves up, so that the seesaw is separated from the cover plate and the clamping part is driven to release the battery shell, and the fixed plate moves down to transport the installed battery outward, and then a robotic arm is provided to take out the installed battery and place a new cover plate for continuous production.

[0025] Beneficial effects of the present invention:

[0026] (1) In the present invention, a glue injection mechanism is provided to inject glue into the cover plate in two steps, thereby achieving precise control of the amount of glue injected into the cover plate, so that the glue at various locations in the cover plate maintains a uniform liquid level. At the same time, the cover plate is tilted so that glue is reserved on the side wall in advance, which facilitates the flow of glue during subsequent assembly and avoids stagnation during subsequent assembly, resulting in bubble retention and unevenness.

[0027] (2) In the present invention, by providing a separating mechanism, the spacer can be precisely placed, and the final position of the spacer can be kept constant, so that the internal structure of the battery can be kept uniform and the production standard can be improved;

[0028] (3) In the present invention, a combination mechanism is used to assist the process of combining the outer shell and the cover plate. By setting the seesaw, most of the glue is pushed outward to avoid a large amount of glue splashing when the outer shell and the cover plate come into contact. At the same time, the glue is prevented from fluctuating unevenly, resulting in differences in the distribution of glue at various locations, which affects the final bonding effect.

[0046] The technical solutions in the embodiments of the present invention are clearly and completely described below in conjunction with the accompanying drawings.

[0047] Embodiment 1

[0048] like Figure 1 , Figure 2 As shown, an automatic lead-acid battery assembly device includes a machine tool and also includes:

[0049] A glue injection mechanism 1, which is arranged on a machine tool and used for injecting glue on the cover plate, and includes a glue injection component 11 arranged for injecting glue on the cover plate and an auxiliary component 12 arranged on the moving component 31 for pre-processing the cover plate;

[0050] The laminating mechanism 2 is arranged on one side of the glue injection mechanism 1 and is used to place a spacer on the battery housing.

[0051] The combination mechanism 3 is arranged behind the slice mechanism 2 and is used to assemble the battery housing and the cover plate. The combination mechanism 3 includes a moving component 31 arranged behind the slice mechanism 2 and an assembling component 32 arranged above the glue injection mechanism 1.

[0052] In this embodiment, the glue injection mechanism 1 and the assembly mechanism 3 are provided to jointly complete the battery assembly work, so that the effect of bonding the battery shell and the cover plate by glue is improved.

[0053] In detail, the glue injection mechanism 1 is used to inject an equal amount of glue at various places of the cover plate, and the glue is covered on the side wall before assembly. At the same time, the isolation sheets are placed by the sheet separation mechanism 2 to keep the positions of each isolation sheet fixed, thereby improving the uniformity of the product. Finally, the outer shell and the cover plate are assembled and bonded by the combination mechanism 3 to further improve the bonding effect of the glue.

[0054] It should be noted that, in the device, the battery casing, isolation sheet and cover plate that have been loaded and cast-welded are input into the device at the same time. After multiple isolation sheets are placed on the battery casing, the battery casing is flipped 180° and combined with the cover plate downward to complete the assembly. The input rate and quantity of the battery casing, isolation sheet and cover plate are coordinated with each other, so that the device can complete continuous production.

[0055] It is worth mentioning that by providing the glue injection mechanism 1 and the combination mechanism 3, the glue is processed to avoid stagnation of the flow of the glue, and to reduce the problems of uneven distribution of the glue and more bubbles that may occur during the assembly process.

[0056] Further, if Figure 3As shown, the glue injection assembly 11 includes a ring conveyor 111 arranged on the machine tool, a plurality of transfer tables 112 arranged on the ring conveyor 111 and transported by the ring conveyor 111, a telescopic cylinder 113 arranged on the transfer table 112, a fixing plate 114 fixed to the end of the telescopic rod of the telescopic cylinder 113 by a universal joint, and a glue injection machine 115 arranged on the outside of the ring conveyor 111.

[0057] In this embodiment, the cover plate is moved by providing a circular conveyor 111 and a transfer table 112. The transfer table 112 is used as a carrying mechanism to realize circular movement, transfer the cover plate and the battery, and cooperate with the continuous production work of the device.

[0058] In detail, the cover is placed on the fixed plate 114 by using a robot arm, so that the cover moves along with the conveyor, and the cover first passes through the moving assembly 31, then passes through the auxiliary assembly 12, and finally passes through the assembly mechanism 3 for assembly. After the assembly is completed, the battery is removed by the robot arm and replaced with a new cover. When the transfer table 112 moves to the bottom of the glue injection machine 115, the glue injection machine 115 injects a proper amount of glue into the cover;

[0059] It should be noted that fixing the fixing plate 114 on the transfer platform 112 by means of a universal joint is conducive to the fixing plate 114 being tilted in all directions.

[0060] It is worth mentioning that by arranging the telescopic cylinder 113 under the fixing platform, it is helpful to raise or lower the fixing plate 114 according to the assembly requirements, thereby facilitating the assembly process.

[0061] Further, if Figure 3 , Figure 4 As shown, the auxiliary component 12 includes a covering member 121 arranged at the rear of the glue injection machine 115 and used for pre-flowing the glue, and a supplementary member 122 arranged at the rear of the covering member 121 and used for secondary glue injection to the cover plate. The covering member 121 includes a dust cover 1211 arranged at the rear of the glue injection machine 115 and fixed on the ring conveyor 111, a swivel 1212 rotatably connected to the turntable 112 and having a gear arranged on the periphery, a first rack 1213 arranged inside the dust cover 1211, and three groups of fixed rods 1214 arranged on the swivel 1212 and controlled by an electric cylinder, wherein the upper end of the fixed rod 1214 is arranged in a smooth spherical shape and contacts the lower bottom surface of the fixed plate 114.

[0062] In this embodiment, the cover member 121 is provided to achieve the tilting of the cover plate on the fixing plate 114, so that the glue in the cover plate can flow to the side wall in advance, which is convenient for subsequent assembly work.

[0063] In detail, the transfer table 112 moves into the dust cover 1211, and the swivel 1212 rotates under the drive of the first rack 1213. At this time, one of the three fixed rods 1214 is raised, and the other two are lowered, so that the fixed plate 114 is tilted. Under the cooperation, the fixed rods 1214 are tilted in different directions, and the glue in the cover plate also tilts, and the glue remains on the side wall of the cover plate to complete the pre-treatment.

[0064] It should be noted that when the outer shell and the cover plate come into contact later, the two combine at a faster speed, and the side walls that are not moistened in advance are more conducive to the flow of glue than the dry side walls. By allowing the glue to remain on the side walls in advance, it is possible to prevent the glue from stagnating during the flow process, resulting in uneven distribution or the appearance of bubbles.

[0065] It is worth mentioning that, by providing the dust cover 1211, the subsequent processing of the glue is all located in an isolated environment to prevent dust from entering.

[0066] Further, if Figure 5 , Figure 6 As shown, the supplementary member 122 includes a pressing plate 1221 disposed inside the dust cover 1211 and connected to the dust cover 1211 by vertical sliding controlled by an electric cylinder, and a glue injection tube 1222 disposed above the pressing plate 1221 and having an outlet connected to the bottom of the pressing plate 1221;

[0067] The edge of the pressing plate 1221 is configured as a slope.

[0068] In this embodiment, by providing a pressing plate 1221 and a glue injection tube 1222, secondary glue injection to the cover plate is achieved, and the residual glue on the side wall of the cover plate is processed at the same time.

[0069] In detail, when the cover moves to the bottom of the pressure plate 1221, the pressure plate 1221 is pressed down and sinks into the groove of the cover. The side walls of the pressure plate 1221 squeeze out the thicker glue on the side walls of the cover and keep the height of the glue consistent. After the pressure plate 1221 moves to a fixed position, the glue injection tube 1222 injects glue into the cover again. After the glue injection is completed, the pressure plate 1221 moves up and the cover continues to move backward.

[0070] It should be noted that by replenishing the glue in the cover plate, on the one hand, the glue in each position can be kept quantitative, and on the other hand, the release amount of glue can be further controlled, so that the cover plate can achieve the best filling effect during the bonding process and just fill the groove.

[0071] It is worth mentioning that the edge of the pressing plate 1221 is set as a bevel, which can process the glue on the side wall of the cover plate, push down the excess glue, and leave only an appropriate amount of glue.

[0072] Further, if Figure 7 , Figure 8 , Fig. 9 As shown, the sheet-splitting mechanism 2 includes a first conveyor belt 21 for conveying battery shells and multiple groups of second conveyor belts 22 for conveying isolation sheets, and also includes a sheet-splitting assembly 23 arranged behind the second conveyor belt 22 for placing isolation sheets and an adjustment assembly 24 arranged behind the sheet-splitting assembly 23 and for adjusting the position of the isolation sheets. The sheet-splitting assembly 23 includes multiple groups of inclined grooves 231 respectively arranged behind the second conveyor belt 22, a baffle 232 with two ends rotatably connected under the inclined groove 231 and a spring arranged between the bottom of the inclined groove 231, and a sheet outlet is arranged at the lower part of the baffle 232.

[0073] In this embodiment, the spacer is placed by providing a sheet assembly 23 so that the spacer can fall into the battery housing accurately.

[0074] In detail, the battery casing is placed on the first conveyor belt 21 and transported into the device, the isolation sheet is placed on the second conveyor belt 22 and transported into the device, the battery is moved to the bottom of the chute 231, the baffle 232 is pushed upward, the outlet of the baffle 232 is aligned with the outlet of the chute 231, and the isolation sheet falls into the battery from the outlet to achieve precise placement.

[0075] It should be noted that multiple isolation sheets need to be placed in one battery, and the first conveyor belt 21 and the second conveyor belt 22 are used to cooperate with each other to avoid empty or over-placed batteries.

[0076] It is worth mentioning that openings are provided at both the upper and lower ends of the inclined slot 231. The upper opening is provided at the tail of the second conveyor belt 22, and a baffle 232 is rotatably connected to the lower opening. When the baffle 232 is not moved upward, it can block the opening of the inclined slot 231, and the isolation plate cannot fall, thereby avoiding possible errors in the speed of the battery and the isolation plate input device.

[0077] Further, if Fig.10 , Fig.11 As shown, the adjustment assembly 24 includes a slide rail 241 arranged behind the inclined groove 231 and respectively located on both sides of the first conveyor belt 21, a sliding block 242 slidably connected to the slide rail 241, two groups of reciprocating racks 243 relatively arranged inside the sliding block 242, an incomplete gear rod 244 arranged between the two groups of reciprocating racks 243 and driven by a motor, a lifting plate 245 that vertically slides at the lower ends of the two groups of sliding blocks 242 and is provided with a spring at the lower part, a cam 246 arranged in the middle of the incomplete gear rod 244, and multiple groups of suction cups 247 arranged below the lifting plate 245.

[0078] In this embodiment, the lifting plate 245 and the sliding block 242 are arranged so that the suction cup 247 can move along a preset track, so that the suction cup 247 can adjust the position of the isolation sheet in the battery.

[0079] In detail, the battery moves to the bottom of the suction cup 247, the motor drives the incomplete gear rod 244 to rotate, the cam 246 on the incomplete gear rod 244 rotates synchronously, the cam 246 presses down the lifting plate 245, the suction cup 247 contacts the isolation plate, and at the same time the incomplete gear rod 244 drives the sliding block 242 to move, so that the suction cup 247 moves synchronously with the isolation plate, and moves the isolation plate toward a predetermined position, so that the positions of all isolation plates are kept constant.

[0080] It should be noted that, due to the setting of the cam 246, the movement trajectory of the suction cup 247 in the whole process is that the suction cup 247 moves horizontally while moving downward, then maintains horizontal movement, and finally moves upward, maintains reverse horizontal movement and resets.

[0081] Further, if Fig.12 As shown, the moving component 31 includes a clamping member 311 arranged behind the first conveyor belt 21, and also includes a first linear motor 312 for horizontally moving the clamping member 311 and a second linear motor 313 arranged on the slider of the first linear motor 312 and used to vertically move the clamping member 311 up and down.

[0082] In this embodiment, the first linear motor 312 and the second linear motor 313 are provided to move the battery, transfer the battery from the first transmission belt to the top of the assembly component 32, and cooperate with the assembly component 32 to assemble the battery.

[0083] It should be noted that, in order to make the device more concise and compact, the first conveyor belt 21 is kept consistent with the center line of the arc conveyor, so that only the first linear motor 312 is needed to complete the movement in one direction.

[0084] Further, if Fig.13 As shown, the clamping member 311 includes a fixed frame 3111 fixedly connected to the slider of the second linear motor 313, a rotating frame 3112 rotatably connected to the fixed frame 3111, a flipping gear 3113 fixedly connected to the outer end of the rotating frame 3112, a flipping rack 3114 arranged on the frame and used to drive the rotating frame 3112 to rotate, a screw rod 3115 rotatably connected to the rotating frame 3112, two sets of clamping plates 3116 respectively arranged at both ends of the screw rod 3115 and threadedly connected to the screw rod 3115, a control gear 3117 fixed on the screw rod 3115, and a combining plate 3118 horizontally slidably connected to the rotating frame 3112 and meshing with the control gear 3117.

[0085] In this embodiment, the clamping plate 3116 and the rotating frame 3112 are provided to achieve the clamping and flipping of the battery.

[0086] In detail, the battery moves on the first conveyor belt 21. As the battery moves, the battery contacts the coupling plate 3118. The coupling plate 3118 is pushed by the battery, thereby driving the screw rod 3115 to rotate, so that the clamping plates 3116 on both sides are clamped to fix the battery, thereby achieving battery clamping. Driven by the first linear motor 312 and the second linear motor 313, the battery first rises and then moves toward the assembly component 32. During the movement, the flipping gear 3113 engages and flips, causing the rotating frame 3112 and the battery to flip up and down.

[0087] It should be noted that the movement of the clamping plate 3116 is driven by the screw rod 3115. Since the screw rod 3115 has a self-locking function, the battery can be prevented from falling during the process.

[0088] It is worth mentioning that, by combining the setting of plate 3118, the position where the battery is clamped can be accurately preset, thereby avoiding the failure of docking between the battery and the cover during the subsequent installation process due to errors in the different positions of the clamped battery.

[0089] Further, if Fig.14 , Fig.15 As shown, the assembly component 32 includes a lifting plate 321 arranged above the circular conveyor 111 and controlled by an electric cylinder, a plurality of sets of seesaw plates 322 rotatably connected to the lifting plate 321 , and a release rack 323 fixedly connected to the lifting plate 321 .

[0090] In this embodiment, the lifting plate 321 and the rocker plate 322 are provided to assist the bonding of the battery and the cover plate, and the rocker plate 322 is used to move the glue to avoid splashing and fluctuation of the glue.

[0091] In detail, when the cover moves to the bottom of the assembly component 32 and the battery moves to the top of the assembly component 32, the lifting plate 321 moves up to the horizontal position under the battery, and the cover moves up, first contacting the seesaw 322, and the seesaw 322 rotates with the height of the cover, thereby moving the glue in the cover to the outside, and then the battery and the cover are combined to complete the bonding, and the lifting plate 321 continues to move up, and the seesaw 322 is separated from the cover, and the rack 323 is released at the same time to contact the control gear 3117, and the clamping is ended. The fixed plate 114 moves down with the battery and follows the circular conveyor 111 to move out to complete the assembly.

[0092] It should be noted that, by using the rocker 322 to push the glue outward, on the one hand, splashing caused by rapid contact between the battery and the cover can be avoided; on the other hand, the movement of the glue caused by the contact between the two can be reduced, so that the glue always maintains the same height and the bonding is more uniform.

[0093] It is worth mentioning that by removing the mating battery from the cover, the inertia caused by the rise is used to further reduce the degree of glue fluctuation, so that the glue everywhere is kept at the same level, thereby improving the bonding quality.

[0094] Embodiment 2

[0095] like Fig.16 As shown, the components identical or corresponding to those in the first embodiment are marked with the corresponding reference numerals in the first embodiment. For the sake of simplicity, only the differences from the first embodiment are described below. The second embodiment differs from the first embodiment in that:

[0096] Further, if Fig.16 As shown, a lead-acid battery automatic assembly process is applied to a lead-acid battery automatic assembly equipment, including the following steps:

[0097] Step 1, glue injection step, the cover plate is fixed on the fixed plate 114 by the mechanical arm, and the glue injection is carried out as the circular conveyor 111 moves to the bottom of the glue injection machine 115. After the glue injection machine 115 injects a part of glue into the cover plate, the cover plate continues to move and enters the dust cover 1211. At this time, one of the three fixed rods 1214 is extended, so that the fixed plate 114 is tilted. At the same time, under the drive of the first rack 1213, the fixed rod 1214 rotates, so that the fixed plate 114 is tilted to the surroundings in turn under the action of the fixed rod 1214, so that the glue in the cover plate is tilted to the edge, so that the glue pre-wet the side wall of the cover plate. After completion, the cover plate continues to move and enters the supplementary part 122, and the pressing plate 1221 moves down to hang down the excess glue remaining on the side wall to keep the glue as uniform as possible. Then, a second glue injection is carried out to keep the glue at each place in the cover plate in the same amount;
