Description

Technical Field

[0001] This invention relates to lead-acid battery assembly technology, and more particularly to a positive and negative electrode alignment assembly system for a lead-acid battery case. Background Technology

[0002] Lead-acid batteries are widely used in various fields due to their high cost-effectiveness and stability. However, the structural design of lead-acid battery boxes is unreasonable, making it easy for operators to misinstall batteries during loading and unloading. Misinstallation not only wastes resources and time but also affects battery performance and lifespan. Therefore, existing lead-acid battery boxes are equipped with anti-misinstallation structures.

[0003] For example, Chinese patent application CN103560217A discloses a battery box for lead-acid batteries used in electric bicycles. In this patent, a limiting protrusion 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 installed incorrectly and also prevent the lead-acid battery from shaking.

[0004] The aforementioned existing technology only discloses the specific structure for preventing misassembly, but still requires manual correction of the orientation, making large-scale assembly line production impossible. Furthermore, lead-acid battery boxes vary in size, requiring individual fitting during assembly, which hinders precise positioning. Therefore, the existing technology needs further improvement. Summary of the Invention

[0005] Based on the above-mentioned technical problems, the present invention proposes a positive and negative electrode calibration assembly system for lead-acid battery boxes.

[0006] The technical solution of this invention is implemented as follows:

[0007] A lead-acid battery case positive and negative electrode alignment and assembly system is disclosed. The lead-acid battery case includes a case body and a case cover. The system is characterized in that the case body has a first limiting structure, and the case cover has a second limiting structure. The first limiting structure and the second limiting structure cooperate to form a concave-convex interlocking structure, which is used to prevent incorrect installation of the positive and negative electrodes.

[0008] The calibration assembly system is used to calibrate the positive and negative poles of the calibration box cover. The calibration assembly system includes a first transport mechanism and a second transport mechanism installed vertically, and a steering mechanism is provided at the corner of the first transport mechanism and the second transport mechanism.

[0009] Both the first and second transport mechanisms are equipped with a gripping mechanism on one side. The gripping mechanism on the side of the first transport mechanism is used to connect the lead-acid battery box cover to the lead-acid battery box body.

[0010] A testing mechanism is provided between the steering mechanism and the second transport mechanism. The testing mechanism is used to detect whether the gripping mechanism on one side of the first transport mechanism can stably install the lead-acid battery box cover on the top of the lead-acid battery box. If not, the gripping mechanism on the second transport mechanism will reconnect the lead-acid battery box cover to the lead-acid battery box.

[0011] In this invention, the first transport mechanism includes a plurality of first legs, a first conveyor belt is disposed above the first legs, and a positioning tray is disposed at one end of the first conveyor belt.

[0012] The box is placed on a positioning tray. Mounting plates are provided on both sides of the first conveyor belt. Support legs are vertically mounted on the mounting plates. Side baffles are installed at an angle upward relative to the support legs. A fixed baffle is provided at one end of the side baffle, and a one-way baffle is provided at the other end. The box cover slides along the side baffle from the one-way baffle to the fixed baffle.

[0013] In this invention, a blocking structure is also provided in the middle of the first conveyor belt. The blocking structure includes a mounting base, which is located on both sides of the first conveyor belt. A first cylinder is provided on the mounting base, and a blocking block is provided on the output shaft of the first cylinder.

[0014] In this invention, the gripping mechanism includes a gripper structure, which includes a telescopic cylinder. One end of the telescopic cylinder is fixed with a connecting plate, and a gripper capable of being driven in multiple directions is provided below the connecting plate. The gripper is used to grip the lid of the box and install it on the box body.

[0015] In this invention, scanning cameras are installed at the four corners of the connecting plate. The scanning cameras are used to scan the long sides of the box body and the box cover, and to make the long sides of the box body and the box cover coincide.

[0016] In this invention, the testing mechanism includes a load-bearing frame installed between the steering mechanism and the second transport mechanism. A gantry frame is mounted above the load-bearing frame, and induction cylinders are respectively installed at the front and rear ends of the gantry frame. The output shaft of the induction cylinder is connected to a pressure roller. A conveyor belt is installed in the middle of the load-bearing frame, which drives the lead-acid battery box to move under the pressure roller, so that the pressure roller is in contact with the top surface of the lead-acid battery box.

[0017] When the output shaft extension length of one of the sensing cylinders is greater than that of the output shaft extension length of the other sensing cylinder, an execution signal is sent to the gripping mechanism on one side of the second transport mechanism.

[0018] In this invention, the calibration assembly system also includes multiple limiting structures installed on both sides of the first transport mechanism, the steering mechanism, the testing mechanism, and the second transport mechanism to prevent the box from shifting during transport and assembly.

[0019] The lead-acid battery box positive and negative electrode alignment assembly system of the present invention has the following beneficial effects:

[0020] This invention achieves stable transportation, precise positioning, efficient assembly, and positive and negative electrode detection of lead-acid battery boxes and covers through streamlined production, thereby improving assembly accuracy and efficiency and reducing the labor intensity of operators.

Detailed Implementation

[0046] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0047] like Figures 1 to 24 As shown, this invention discloses a positive and negative electrode calibration assembly system for a lead-acid battery case, including a lead-acid battery case 100 and a calibration assembly system 200. Wherein, as... Figures 1 to 3As shown, the lead-acid battery case 100 includes a case body 110 and a case cover 111. A boss 110A is provided on the top of the case body 110, and a groove 111A is provided on the inner side of the case cover 111. The boss 110A and the groove 111A are engaged to connect the case body 110 and the case cover 111. Multiple partitions 110C are provided inside the case body 110, dividing the interior into multiple battery slots 110B for accommodating lead-acid battery electrodes. A slot 110D is provided above the partitions 110C for accommodating the connecting wires between pairs of lead-acid battery electrodes.

[0048] The top of the cover 111 is provided with a terminal 112, which consists of a positive terminal 112A and a negative terminal 112B. Inside the cover 111, opposite to the battery compartment 110B, a top ring 111B is provided to restrict the movement of the lead-acid battery electrodes within the battery compartment 110B. Inside the cover 111, opposite to the slot 110D, a locking block 111C is provided to restrict the offset of the connecting wire between the two lead-acid battery electrodes. Limiting edges 111D are also provided on both sides of the top ring 111B, which guide the partial alignment of the connecting wire between the two lead-acid battery electrodes.

[0049] The box body 110 is provided with a first limiting structure 113, and the box lid 111 is provided with a second limiting structure 114. The first limiting structure 113 and the second limiting structure 114 cooperate to form a concave-convex interlocking structure. That is, the first limiting structure 113 is a protrusion 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 protrusion structure. When the first limiting structure 113 and the second limiting structure 114 are located on the same side of the box body 110, the first limiting structure 113 and the second limiting structure 114 cooperate, and the box lid 111 is stably connected to the top of the box body 110; when the first limiting structure 113 and the second limiting structure 114 are located on opposite sides of the box body 110, the first limiting structure 113 and the second limiting structure 114 cannot cooperate, and the box lid 111 is tilted and connected to the top of the box body 110.

[0050] like Figure 4 As shown, the size of the box 110 varies depending on the product model. Multiple partitions 110C can be arranged longitudinally and laterally inside the box 110, dividing the inside of the box 110 into multiple battery slots 110B arranged longitudinally and laterally.

[0051] Furthermore, such as Figure 5As shown, the calibration assembly system 200 is used to install and calibrate lead-acid battery boxes 100 of various models. The calibration assembly system 200 includes a first transport mechanism 21 and a second transport mechanism 25 installed vertically. A turning 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 turning mechanism 23. A gripping mechanism 23 is provided on one side of both the first transport mechanism 21 and the second transport mechanism 25. The gripping mechanism 23 on the first transport mechanism 21 is used to connect the lead-acid battery box cover 111 to the lead-acid battery box body 110. A testing mechanism 24 is provided between the turning mechanism 23 and the second transport mechanism 25. The testing mechanism 24 is used to detect whether the gripping mechanism 23 on the first transport mechanism 21 stably installs the lead-acid battery box cover 111 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 will grip the lead-acid battery box cover 111 and rotate it 180° to reconnect it to the lead-acid battery box body 110.

[0052] like Figures 6 to 9 As shown, the first transport mechanism 21 includes multiple first legs 211, with a first conveyor belt 213 positioned above each first leg 211. A positioning tray 212 is attached to one end of the first conveyor belt 213. The box 110 is placed on the positioning tray 212, and then the first conveyor belt 213 is activated to transport the box 110 away from the positioning tray 212. Mounting plates 214 are also provided on both sides of the first conveyor belt 213. Support legs are vertically mounted on the mounting plates 214, and side baffles 216 are mounted at an angle upward relative to the support legs. A fixed baffle 215 is provided at one end of the side baffle 216, and a one-way baffle 217 is provided at the other end. The box cover 111 slides along the side baffle 216 from the one-way baffle 217 to the fixed baffle 215.

[0053] The gripping mechanism 23 on one side of the first conveyor belt 213 is used to connect the box cover 111 on the side panel baffle 216 to the box body 110 on the first conveyor belt 213. A blocking structure 31, including a mounting base 311, is also provided in the middle of the first conveyor belt 213. The mounting base 311 is located on one or both sides of the first conveyor belt 213, and a first cylinder 312 is provided on the mounting base 311. A blocking block 313 is provided on the output shaft of the first cylinder 312. When the gripping mechanism 23 connects the box cover 111 to the box body 110, the blocking block 313 restricts the box body 110 from continuing to move away from the positioning tray 212. Restriction structures 32 are also provided on both sides of the first conveyor belt 213. The restriction structures 32 engage with both sides of the box body 110 to prevent the box body 110 from shifting during transportation and assembly.

[0054] like Figure 9As shown, the limiting structure 32 includes two mounting legs 321, each with a first fixing member 322 that can rotate circumferentially along the mounting leg 321. An adjusting rod 323 is slidably mounted on the first fixing member 322, and a second fixing member 324 is mounted on the adjusting rod 323 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, which 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 can be adjusted to shift inward, or the second inclined end 325B of the limiting plate 325 can be adjusted to shift inward, or both the first inclined end 325A and the second inclined end 325B can be adjusted to shift inward together, thereby limiting lead-acid battery boxes of different sizes.

[0055] like Figures 10 to 12 As shown, the gripping mechanism 23 includes a base 221, on which a circumferential rotating member 222 is mounted. A first driving end 223 is located on one side of the circumferential rotating member 222, and a first swing arm 224 is connected to the first driving end 223. A second swing arm 225 is located at the other end of the first swing arm 224. A second driving end 226 is located at the other end of the second swing arm 225, and the second driving end 226 is connected to a third swing arm 227. A gripper structure 33 is located below the third swing arm 227 for gripping the lid 111 and engaging it with the box body 110.

[0056] In this embodiment, the gripper structure 33 includes a telescopic cylinder 331. One end of the telescopic cylinder 331 is fixed to a connecting plate 332, which slides up and down along the third swing arm 227 via 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 gripper 335 capable of pneumatic opening and closing is provided below the transverse sliding block 334. A drive cylinder 336 is provided at the bottom of the connecting plate 332, and the output shaft of the drive cylinder 336 is connected to the longitudinal sliding block 333 to control the movement of the longitudinal sliding block 333 in the Y direction of the connecting plate 332. The gripper structure 33 is controlled by a PLC program to grip the lid 111, and the lid 111 is installed on the box body 110 by the sequential operation of the drive components of the gripping mechanism 23.

[0057] Because the lead-acid battery boxes 100 vary in size, precise positioning cannot be achieved solely 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 box cover 111, and then the gripping structure 23 is used to align the long sides of the box body 110 and the box cover 111 to achieve precise positioning and installation.

[0058] Furthermore, such as Figures 13 to 17 As shown, when the box body 110 moves on the first conveyor belt 213, its movement is restricted by the blocking structures 31 on both sides of the first conveyor belt 213. At this time, the box lid 111 is gripped by the gripping mechanism 22 and aligned with the box body 110. During the alignment process, the gripping mechanism 22 also aligns the wide edge of the box lid 111 with the blocking structure 31, and the blocking structures 31 on both sides of the first conveyor belt 213 straighten the box lid 111, aligning the wide edge of the box lid 111 with the wide edge of the box body 110. Then, the scanning camera 337 scans the long sides of the box body 110 and the box lid 111 respectively. When scanning the long side of the box body 110, the wide side of the box body 110 that is in contact with the blocking structure 31 is set as the first reference side. The scanning camera 337 scans the long side that intersects with the first reference side to obtain the first scanning curve. When scanning the long side of the box lid 111, the wide side of the box lid 111 that is in contact with the blocking structure 31 is set as the second reference side. The scanning camera 337 scans the long side that intersects with the second reference side to obtain the second scanning curve. Then, the gripping mechanism 22 moves the box lid 111 to make the second scanning curve coincide with the first scanning curve, achieving precise positioning.

[0059] In particular, under the illumination of the workshop production lights, reflections are easily generated, which can cause distortion, concavity or bending of the scanning curve recognized by the scanning camera 337. It is necessary to correct the first scanning curve and the second scanning curve respectively.

[0060] Specifically, the first scan curve correction step includes:

[0061] Step 100: Obtain N target points G on the first scanning curve, and set the intersection of the first scanning curve and the first reference edge as the target point G1;

[0062] Step 200: Establish a coordinate system with target point G1 as the origin, and set the target points... ;

[0063] Step 300: Based on the coordinate coefficients of N target points G, determine whether two target points G are in an upward or downward trend, and calculate the angle θ between the two target points G.

[0064] Step 400: Correct the N target points G. The correction point of target point G2 is J2, and the coordinates of the correction point J2 are (P1, Y1).

[0065] Step 500: Correct the point set K is the number of correction points, K=N-1, and P is the correction coordinate, P=Xcosθ+Ysinθ.

[0066] Step 600: Repeat Step 300 to Step 500 until all N target points G are repaired to obtain the first correction curve. The second scan curve is corrected in the same way to obtain the second correction curve. The second correction curve is then overlapped with the first correction curve to increase the positioning accuracy.

[0067] To ensure production efficiency, the positive and negative orientations of the box body 110 and box lid 111 are not manually distinguished when they are placed on the positioning tray 212 and the fixing baffle 215. Therefore, it is impossible to determine whether the box lid 111 is stably installed on the box body 110. Hence, the box lid 111 still needs to be inspected and calibrated.

[0068] After the cover 111 is installed on the box body 110, the first cylinder 312 drives the blocking block 313 to retract, so that the blocking block 313 no longer restricts the lead-acid battery box 100 from continuing to move. The steering mechanism 23 is installed at one end of the first conveyor mechanism 21. A roller 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 roller 218, it is then moved by the steering mechanism 23 to directly below the testing mechanism 24 to check whether the cover 111 is stably installed on the box body 110.

[0069] like Figures 18 to 20 As shown, the steering mechanism 23 includes a second leg 231, on which multiple first rods 232 are mounted, perpendicular to the roller 218. A steering assembly 235 is located at the corner where the first rods 232 meet the roller 218. The steering assembly 235 consists of a support plate 235A, an adjusting groove 235B, and a steering wheel 235C. The steering wheel 235C is rotatably connected to one end of the support plate 235A. A drive motor is mounted at the bottom of the support plate 235A, and the output shaft of this drive motor is connected to the steering wheel 235C, enabling it to drive the steering wheel 235C along... Figure 19The direction of the arrow is rotated. When the lead-acid battery box 100 moves along the first conveyor belt 213, the steering wheel 235C is in contact with 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. An adjustment groove 235B is provided at the end of the support plate 235A away from the steering wheel 235C, allowing the steering wheel 235C to be in contact with one side of lead-acid battery boxes 100 of different sizes. A first side plate 233 is also provided at the end of the second support leg 231 away from the first conveying mechanism 21. A push-pull cylinder 234 is mounted 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 rotational torque of the steering wheel 235C, the output shaft of the push-pull cylinder 234 drives the push plate 234A to retract. 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 rotate 90°.

[0070] In this embodiment, a limiting structure 32 is provided on both sides of the first rod 232. After the lead-acid battery box 100 changes direction, the limiting structure 32 corrects the position of the lead-acid battery box 100 so that it can move stably towards the testing mechanism 24 along the horizontal direction of the first rod 232.

[0071] like Figures 21 to 24 As shown, the testing mechanism 24 includes a load-bearing frame 241, which is installed between the steering mechanism 23 and the second transport mechanism 25. A gantry frame 242 is mounted above the load-bearing frame 241. Induction cylinders 243 are respectively installed at the front and rear ends of the gantry frame 242. The output shaft of the induction cylinder 243 is connected to a pressure roller 244. Initially, the two pressure rollers are at the same vertical height. A conveyor belt 245 is installed in the middle of the load-bearing frame 241, which drives the lead-acid battery box 100 to move below the pressure roller 244.

[0072] Furthermore, a slide groove 246 is provided below the load-bearing frame 241, and a first connecting rod 247 is slidably mounted inside the slide groove 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 bonding plate 2410 is provided on the rotating rod 248. By moving the first connecting rod 247 within the slide groove 246, the deflection angle of the bonding plate 2410 is adjusted, causing the lead-acid battery box 100 to move further towards the center of the conveyor belt 245, ensuring that the testing mechanism 24 can better detect whether the lead-acid battery box 100 is installed stably.

[0073] In this embodiment, the testing mechanism 24 is used to detect whether the cover 111 is stably installed on the box body 110. If the cover 111 is installed at an angle on the box body 110, one end of the cover 111 is higher than the other end. After the lead-acid battery box 100 moves below the pressure roller 244, the output shaft of the sensing cylinder 243 drives the pressure roller 244 to move downward, so that the two pressure rollers 244 are in contact with the top of the cover 111. When the extension length of the output shaft of one sensing cylinder 243 is greater than the extension length of the output shaft of the other sensing cylinder 243, it indicates that the cover 111 is installed at an angle above the box body 110, and an execution signal is sent to the gripping mechanism 22 on one side of the second transport mechanism 25. The second transport mechanism 25 includes a third leg 251, a second side plate 252, and a second rod 253. The second side plate 252 is provided with multiple limiting structures 32 for engaging with both sides of the lead-acid battery box 100. The second transport mechanism 25 is also equipped with a blocking structure 31 at one end. The blocking structure 31 is used to restrict the lead-acid battery box 100 from moving further. Then, the box cover 111 is correctly installed on the box body 110 by the gripping mechanism 22 on one side of the second transport mechanism 25. If the extension length of the output shaft of one of the sensing cylinders 243 is the same as the extension length of the output shaft of the other sensing cylinder 243, it means that the box cover 111 is stably installed above the box body 110. An execution signal is sent to the blocking structure 31 at one end of the second transport mechanism 25, so that the lead-acid battery box 100 can pass directly without further correction.
