Technical Field

[0001] The present invention relates to the assembly technology of lead-acid batteries, and particularly to a positive and negative pole correction and assembly system for a lead-acid battery box. Background Art

[0002] Due to its high cost performance and stability, lead-acid batteries are widely used in various fields. However, the structural design of the lead-acid battery box is unreasonable, and it is easy for operators to misinstall the battery when loading and unloading the battery. Misinstallation not only wastes resources and time, but also affects the performance and service life of the battery. Therefore, existing lead-acid battery boxes are provided with anti-misinstallation structures.

[0003] For example, Chinese Patent Application CN103560217A discloses a battery box for a lead-acid battery used in an electric bicycle. In this patent, a convex platform for limiting is provided on the inner wall of the bottom of the box at the end of the lead-acid battery, which can effectively prevent the lead-acid battery from being misinstalled and prevent the lead-acid battery from shaking.

[0004] The above-mentioned prior art only discloses the specific structure of anti-misinstallation, but still requires manual correction of the direction and cannot realize large-scale production line production. Moreover, the sizes of lead-acid battery boxes are different, and they need to be adapted one by one during assembly, and accurate positioning cannot be completed. Therefore, the prior art needs to be further improved. Summary of the Invention

[0005] Based on the above technical problems, the present invention proposes a positive and negative pole correction and assembly system for a lead-acid battery box.

Among them, The correction and assembly system is used to correct the positive and negative poles of the box cover. The correction and assembly system includes a first transportation mechanism and a second transportation mechanism installed vertically. A steering mechanism is provided at the corner of the first transportation mechanism and the second transportation mechanism.

The grasping mechanism on one side of the first transportation mechanism is used to connect the lead-acid battery box cover and the lead-acid battery box body in cooperation. A testing mechanism is provided between the steering mechanism and the second transportation mechanism. The testing mechanism is used to detect whether the grasping mechanism on one side of the first transportation mechanism installs the lead-acid battery box cover stably on the top of the lead-acid battery box body; if not, the grasping mechanism on one side of the second transportation mechanism reconnects the lead-acid battery box cover and the lead-acid battery box body.

[0007] In the present invention, the first transport mechanism includes a plurality of first legs. Above the first legs, a first conveyor belt is provided.

The lead-acid battery box is driven by the conveyor belt to move below the pressure wheel, so that the pressure wheel is in contact with the top surface of the lead-acid battery box. When the elongation length of the output shaft of one of the induction cylinders is greater than the elongation length of the output shaft of the other induction cylinder, an execution signal is sent to the grasping mechanism on one side of the second transport mechanism.

Detailed implementation manners

[0015] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0016] As Figures 1 to 24 shown, the present invention discloses a positive and negative calibration and assembly system for a lead - acid battery box, including a lead - acid battery box 100 and a calibration and assembly system 200. Among them, as Figures 1 to 3As shown, the lead-acid battery box 100 includes a box body 110 and a box cover 111. A boss 110A is provided above the box body 110, and a groove 111A is provided inside the box cover 111. The boss 110A and the groove 111A are cooperatively connected to connect the box body 110 and the box cover 111. A plurality of partitions 110C are provided inside the box body 110. The box body 110 is divided into a plurality of battery slots 110B by the partitions 110C, and the battery slots 110B are used to accommodate lead-acid battery electrodes. A card slot 110D is provided above the partition 110C, and the card slot 110D is used to accommodate the connection wires between two lead-acid battery electrodes.

[0017] A wiring terminal 112 is provided at the top of the box cover 111. The wiring terminal 112 is composed of a positive wiring port 112A and a negative wiring port 112B. A top ring 111B is provided inside the box cover 111 at a position opposite to the battery slot 110B. The top ring 111B is used to limit the movement of the lead-acid battery electrodes in the battery slot 110B. A clamping block 111C is provided inside the box cover 111 at a position opposite to the card slot 110D. The clamping block 111C is used to limit the offset of the connection wires between two lead-acid battery electrodes. Limiting edges 111D are further provided on both sides of the top ring 111B, and the limiting edges 111D are used to guide the arrangement of part of the connection wires between two lead-acid battery electrodes.

[0018] Among them, a first limiting structure 113 is provided on the box body 110, and a second limiting structure 114 is provided on the box cover 111. The first limiting structure 113 and the second limiting structure 114 cooperate to form a concave-convex clamping structure. That is, the first limiting structure 113 is a convex block structure and the second limiting structure 114 is a groove structure, or the first limiting structure 113 is a groove structure and the second limiting structure 114 is a convex block structure. When the first limiting structure 113 and the second limiting structure 114 are on the same side of the box body 110, the first limiting structure 113 and the second limiting structure 114 cooperate, and the box cover 111 is stably connected above the box body 110; when the first limiting structure 113 and the second limiting structure 114 are on both sides of the box body 110 respectively, the first limiting structure 113 and the second limiting structure 114 cannot cooperate, and the box cover 111 is obliquely connected above the box body 110.

[0019] As Figure 4 shown, the size of the box body 110 changes with the product model. A plurality of partitions 110C can be arranged longitudinally and horizontally inside the box body 110, so that the box body 110 is divided into a plurality of battery slots 110B distributed longitudinally and horizontally.

[0020] Furthermore, as Figure 5As shown, the calibration and assembly system 200 is used to install and calibrate lead-acid battery boxes 100 of multiple models. The calibration and assembly system 200 includes a first transport mechanism 21 and a second transport mechanism 25 that are vertically installed. A steering mechanism 23 is provided at the corner of the first transport mechanism 21 and the second transport mechanism 25. The lead-acid battery box 100 is transported from the first transport mechanism 21 to the second transport mechanism 25 via the steering mechanism 23. Gripping mechanisms 23 are provided on one side of both the first transport mechanism 21 and the second transport mechanism 25. The gripping mechanism 23 on one side of the first transport mechanism 21 is used to connect and cooperate the lead-acid battery box cover 111 with the lead-acid battery box body 110. A testing mechanism 24 is provided between the steering mechanism 23 and the second transport mechanism 25. The testing mechanism 24 is used to detect whether the gripping mechanism 23 on one side of the first transport mechanism 21 installs the lead-acid battery box cover 111 stably on the top of the lead-acid battery box body 110. If not, the gripping mechanism 23 on one side of the second transport mechanism 251 grabs the lead-acid battery box cover 111 and rotates it 180° to reconnect it with the lead-acid battery box body 110.

[0021] As Figures 6 to 9 shown, the first transport mechanism 21 includes a plurality of first legs 211. Above the first legs 211, there is a first conveyor belt 213. One end of the first conveyor belt 213 is provided with a positioning tray 212. The box body 110 is placed on the positioning tray 212, and then the first conveyor belt 213 is started to convey the box body 110 away from the positioning tray 212. Installation plates 214 are also provided on both sides of the first conveyor belt 213. Support legs are vertically and perpendicularly installed on the installation plates 214, and side baffle plates 216 are installed obliquely upward with the support legs. One end of the side baffle plate 216 is provided with a fixed baffle plate 215, and the other end is provided with a one-way baffle plate 217. The box cover 111 slides along the side baffle plate 216 from the one-way baffle plate 217 to one end of the fixed baffle plate 215.

[0022] Among them, the gripping mechanism 23 on one side of the first conveyor belt 213 is used to connect and cooperate the box cover 111 on the side baffle plate 216 with the box body 110 on the first conveyor belt 213. A blocking structure 31 is also provided in the middle of the first conveyor belt 213. The blocking structure 31 includes a mounting seat 311. The mounting seat 311 is located on one side or both sides of the first conveyor belt 213. A first cylinder 312 is provided on the mounting seat 311, and a blocking block 313 is provided on the output shaft of the first cylinder 312. When the gripping mechanism 23 connects and cooperates the box cover 111 with the box body 110, the box body 110 is restricted from continuing to move away from the positioning tray 212 by the blocking block 313. Restricting structures 32 are also provided on both sides of the first conveyor belt 213. The restricting structures 32 are clamped on both sides of the box body 110 to prevent the box body 110 from shifting during transportation and assembly.

[0023] As Figure 9As shown, the limiting structure 32 includes two mounting legs 321, and a first fixing member 322 is provided on each mounting leg 321. The first fixing member 322 can rotate circumferentially along the mounting leg 321. An adjusting rod 323 is slidably arranged on the first fixing member 322, and a second fixing member 324 is arranged on the adjusting rod 323. The second fixing member 324 is used to limit the sliding stroke of the adjusting rod 323 on the first fixing member 322. The two adjusting rods 323 are hinged to the same limiting plate 325, and the limiting plate 325 also has a first inclined end 325A and a second inclined end 325B. By sliding the two adjusting rods 323 along the first fixing member 322 and rotating the first fixing member 322 circumferentially along the mounting leg 321, the first inclined end 325A of the limiting plate 325 is adjusted to offset inward, or the second inclined end 325B of the limiting plate 325 is adjusted to offset inward, or both the first inclined end 325A and the second inclined end 325B offset inward together, so as to realize the limitation of lead-acid battery boxes of different sizes.

[0024] As Figures 10 to 12 shown, the grasping mechanism 23 includes a base 221, and a circumferential rotating member 222 is arranged on the base 221. A first driving end 223 is arranged on one side of the circumferential rotating member 222. The first driving end 223 is connected to a first swing arm 224, and the other end of the first swing arm 224 is provided with a second swing arm 225. The other end of the second swing arm 225 is provided with a second driving end 226, and the second driving end 226 is connected to a third swing arm 227. A jaw structure 33 is arranged below the third swing arm 227 for grasping the lid 111 and the box body 110 to be fitted and connected.

[0025] In this embodiment, the jaw structure 33 includes a telescopic cylinder 331. One end of the telescopic cylinder 331 is fixed with a connecting plate 332, and the connecting plate 332 slides up and down along the third swing arm 227 through the telescopic cylinder 331. A longitudinal sliding block 333 is slidably connected to the connecting plate 332 in the Y direction, and a transverse sliding block 334 is slidably connected to the longitudinal sliding block 333 in the X direction. A jaw 335 capable of pneumatically opening and closing is arranged below the transverse sliding block 334. A driving cylinder 336 is arranged at the bottom of the connecting plate 332, and the output shaft of the driving cylinder 336 is connected to the longitudinal sliding block 333 for controlling the movement of the longitudinal sliding block 333 in the Y direction of the connecting plate 332. The jaw structure 33 is controlled by a PLC program to pick up the lid 111, and the driving components of the grasping mechanism 23 work successively to install the lid 111 on the box body 110.

[0026] Since the sizes of the lead-acid battery boxes 100 are different, accurate positioning cannot be achieved only through PLC program control. Therefore, scanning cameras 337 are installed at the four corners of the connecting plate 332. The scanning cameras 337 are used to scan the long sides of the box body 110 and the lid 111, and then the long sides of the box body 110 and the lid 111 are overlapped through the grasping structure 23 to achieve accurate positioning and installation.

[0027] Further, as Figures 13 to 17 shown, when the box body 110 moves on the first conveyor belt 213, its continuous movement is restricted by the blocking structures 31 on both sides of the first conveyor belt 213. At this time, the grasping mechanism 22 then grabs the box cover 111 and aligns it with the box body 110. During the alignment process, the wide side of the box cover 111 is also made to fit against the blocking structures 31 by the grasping mechanism 22, and the box cover 111 is straightened by the blocking structures 31 on both sides of the first conveyor belt 213, and the wide side of the box cover 111 is aligned with the wide side of the box body 110. Subsequently, the long sides of the box body 110 and the box cover 111 are respectively scanned by the scanning camera 337. When scanning the long side of the box body 110, the wide side of the box body 110 that fits against the blocking structures 31 is set as the first reference edge, and the long side intersecting with the first reference edge is scanned by the scanning camera 337 to obtain the first scanning curve; when scanning the long side of the box cover 111, the wide side of the box cover 111 that fits against the blocking structures 31 is set as the second reference edge, and the long side intersecting with the second reference edge is scanned by the scanning camera 337 to obtain the second scanning curve. Then, the grasping mechanism 22 drives the box cover 111 to move, and the second scanning curve is made to coincide with the first scanning curve to achieve precise positioning.

[0028] Among them, under the illumination of the workshop production lights, it is easy to generate reflections, resulting in distortion, dents, or bending of the scanning curves recognized by the scanning camera 337, and the first scanning curve and the second scanning curve need to be corrected separately.

[0029] Specifically, the first scanning curve correction steps include: Step100: Obtain N target points G on the first scanning curve, and set the intersection point of the first scanning curve and the first reference edge as the target point G 1 ; Step200: Establish a coordinate system with the target point G 1 as the origin, and the target point set ; Step300: According to the coordinate coefficients of the N target points G, determine whether the trend between two target points G is upward or downward, and calculate the included angle θ between the two target points G; Step400: Correct the N target points G, and the correction point of the target point G 2 is J 2 , and the coordinates of the correction point J 2 are (P 1 , Y 1 ), Step500: The correction point set , K is the number of correction points, K = N - 1, P is the correction coordinate, and P = Xcosθ + Ysinθ.

[0030] Step 600: Repeat Step 300 to Step 500 until all N target points G are repaired to obtain the first corrected curve. Among them, the second scanned curve is corrected in the same way to obtain the second corrected curve, and the second corrected curve is made to coincide with the first corrected curve to improve the positioning accuracy.

[0031] Since to ensure production efficiency, when the box body 110 and the box cover 111 are placed on the positioning tray 212 and the fixed baffle 215, the positive and negative polar orientations are not manually distinguished. Therefore, it is impossible to determine whether the box cover 111 is stably installed above the box body 110. Thus, it is still necessary to detect and correct the box cover 111.

[0032] After the box cover 111 is installed on the box body 110, the first air cylinder 312 drives the blocking block 313 to contract, so that the blocking block 313 no longer restricts the continued movement of the lead-acid battery box 100. Among them, the steering mechanism 23 is installed at one end of the first conveying mechanism 21. A rolling 218 is provided at the end of the first conveyor belt 213 away from the positioning tray 212. When the lead-acid battery box 100 moves to the rolling 218, it then moves to directly below the testing mechanism 24 through the steering mechanism 23 to detect whether the box cover 111 is stably installed on the box body 110.

[0033] As Figures 18 to 20 shown, the steering mechanism 23 includes a second leg 231. A plurality of first rods 232 are provided on the second leg 231, and the first rods 232 are perpendicularly installed to the rolling 218. A steering group 235 is provided at the corner of the first rod 232 and the rolling 218. The steering group 235 is composed of a bearing plate 235A, an adjustment groove 235B, and a steering wheel 235C. The steering wheel 235C is rotatably connected to one end of the bearing plate 235A. A driving motor is installed at the bottom of the bearing plate 235A, and the output shaft of the driving motor is connected to the steering wheel 235C and can drive the steering wheel 235C along Figure 19It rotates in the direction of the arrow. When the lead-acid battery box 100 moves along the first conveyor belt 213, the steering wheel 235C fits against one side of the lead-acid battery box 100, and the rotation of the steering wheel 235C forces the lead-acid battery box 100 to deflect. Among them, an adjustment groove 235B is provided at one end of the bearing plate 235A away from the steering wheel 235C. Through this adjustment groove 235B, the steering wheel 235C can always fit against one side of the lead-acid battery box 100 with different sizes. One end of the second leg 231 away from the first conveying mechanism 21 is also provided with a first side plate 233. A push-pull cylinder 234 is installed on the first side plate 233, and a push plate 234A is provided on the output shaft of the push-pull cylinder 234. When the lead-acid battery box 100 deflects due to the torque of the steering wheel 235C, the output shaft of the push-pull cylinder 234 drives the push plate 234A to contract. The push plate 234A contacts the side of the lead-acid battery box 100 away from the steering wheel 235C and pushes the lead-acid battery box 100 to turn 90°.

[0034] In this embodiment, limiting structures 32 are also provided on both sides of the first rod 232. After the lead-acid battery box 100 turns, the position of the lead-acid battery box 100 is corrected by the limiting structures 32, so that it can stably move horizontally along the first rod 232 towards the testing mechanism 24.

[0035] As Figures 21 to 24 shown, the testing mechanism 24 includes a load-bearing frame 241, and the load-bearing frame 241 is installed between the steering mechanism 23 and the second transportation mechanism 25. A gantry 242 is provided above the load-bearing frame 241, and induction cylinders 243 are respectively provided at the front and rear ends of the gantry 242. The output shafts of the induction cylinders 243 are connected to a pressure wheel 244. In the initial state, the two pressure wheels are at the same vertical height. A conveyor belt 245 is provided in the middle of the load-bearing frame 241, and the conveyor belt 245 drives the lead-acid battery box 100 to move below the pressure wheel 244.

[0036] Furthermore, a chute 246 is also provided below the load-bearing frame 241, and a first connecting rod 247 is slidably arranged inside the chute 246. The other end of the first connecting rod 247 is connected to a second connecting rod 249. The second connecting rod 249 is connected to a rotating rod 248, and a fitting plate 2410 is provided on the rotating rod 248. By moving the first connecting rod 247 in the chute 246, the deflection angle of the fitting plate 2410 is adjusted, so that the lead-acid battery box 100 further tends to the middle of the conveyor belt 245, ensuring that the testing mechanism 24 can better detect whether the lead-acid battery box 100 is installed stably.

[0037] In this embodiment, the testing mechanism 24 is used to detect whether the lid 111 is stably installed on the box body 110. If the lid 111 is installed on the box body 110 obliquely, one end of the lid 111 is higher than the other end of the lid 111. After the lead-acid battery box 100 moves under the pressing wheels 244, the output shaft of the induction cylinder 243 drives the pressing wheels 244 to move downward together, so that the two pressing wheels 244 are in contact with the top of the lid 111. When the elongation length of the output shaft of one of the induction cylinders 243 is greater than the elongation length of the output shaft of the other induction cylinder 243, it indicates that the lid 111 is installed obliquely above the box body 110, and an execution signal is sent to the grasping mechanism 22 on one side of the second transportation mechanism 25. Among them, the second transportation mechanism 25 includes a third leg 251, a second side plate 252 and a second rod 253. A plurality of limiting structures 32 are arranged on the second side plate 252 for clamping on both sides of the lead-acid battery box 100. A blocking structure 31 is also arranged at one end of the second transportation mechanism 25. The blocking structure 31 is used to limit the continuous movement of the lead-acid battery box 100, and then the lid 111 is corrected and installed on the box body 110 through the grasping mechanism 22 on one side of the second transportation mechanism 25. If the elongation length of the output shaft of one of the induction cylinders 243 is the same as the elongation length of the output shaft of the other induction cylinder 243, it indicates that the lid 111 is stably installed above the box body 110, and an execution signal is sent to the blocking structure 31 at one end of the second transportation mechanism 25, so that the lead-acid battery box 100 can pass directly without further correction.
