Description

Technical Field

[0001] This invention belongs to the technical field of lead-acid battery plate production equipment, and in particular, it is an integrated device for high-precision weighing and sorting of lead-acid battery plates. Background Technology

[0002] Lead-acid batteries consist of plates, electrolyte, separators, lead connectors, terminals, and a casing. Among these, the plates are the core component, and their manufacturing characteristics affect the overall battery performance. Existing research indicates that the consistency of plate weight is crucial in lead-acid battery manufacturing; excessive weight variations in the coated plates directly lead to a shortened battery life. Therefore, it is necessary to weigh the plates after the coating process and classify plates from different weight ranges.

[0003] Currently, most companies still use a sampling inspection method for weighing. Operators randomly select plates from the transport equipment and weigh them on a weighing machine. If more than one plate in the same batch fails, the entire batch is considered unsuitable and requires re-inspection of each plate. This method is inefficient, failing to classify plates according to weight ranges and wasting significant manpower, resulting in losses for companies. Application number CN201510002893.8 authorizes a multi-station automatic weighing and grouping device for lead-acid battery plates. This device uses vacuum suction cups to adsorb plates for weighing and sorting, effectively improving the accuracy and automation of plate detection during weighing and sorting. However, the rough surface of the coated plates, often covered with dust, makes the vacuum suction cups prone to clogging, increasing equipment failure rates and making practical application in production difficult. The invention patent with application number CN201711343592.7 discloses an online parallel weighing and detection device for small-sized products. It weighs the electrode plates and the conveying device of the part where the electrode plates are located together, which effectively improves the work efficiency of the weighing process. However, it ignores the fact that the accuracy of the electrode plate weight is generally within 2g. This accuracy is difficult to achieve on a continuously running production line, resulting in the inability to guarantee the accuracy of electrode plate weighing. In addition, this patent can only realize weighing and does not have a sorting function. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a high-precision weighing and sorting integrated device for lead-acid battery plates that can accurately measure the weight of the plates without affecting the plate conveying efficiency or causing damage to the plate surface, and can quickly sort the plates according to the weight range.

[0031] The structure of the present invention will be further described below with reference to the accompanying drawings and embodiments. It should be noted that these embodiments are descriptive and not limiting.

[0032] Please refer to the integrated device for high-precision weighing and sorting of lead-acid battery plates. Figures 1-5 The invention features the following components: 1. base, 2. human-machine interface, 3. weighing and sorting, 4. belt drive and conveying, and 5. control device.

[0033] The base portion 1 is fixed relative to the ground and includes a base platform 11, foot cups 12, and an electrode plate buffer device 13. The base platform adopts a box structure along its length, and multiple foot cups are installed at the lower end of the base platform, which contact the ground. The electrode plate buffer device is installed at the upper end of the base platform.

[0034] The human-computer interaction part 2 is connected to the side of the base platform 11.

[0035] The weighing and sorting section 3 includes a slide table 31, a slide table conveying device 32, a material picking and weighing device 33, and an electrode plate conveying device 34. The slide table is connected to the top of the base platform via the slide table conveying device, allowing the slide table 31 to reciprocate linearly along the base platform 11 in a horizontal plane within a certain range, perpendicular to the electrode plate conveying direction. The material picking and weighing device and the electrode plate conveying device are installed above the slide table and move together with the slide table.

[0036] The belt-driven conveyor section 4 includes an upper-level belt conveyor mechanism 41 and a lower-level belt conveyor mechanism 42. The upper-level and lower-level belt conveyor mechanisms are respectively located on both sides of the base platform. The upper-level belt conveyor mechanism 41 conveys the coated electrode plates to the weighing and sorting section 3 for weighing and sorting. After the weighing and sorting process, the electrode plate conveying device 34 conveys the electrode plates to the lower-level belt conveyor mechanism 42. The lower-level belt conveyor mechanism 42 includes, but is not limited to, a first belt conveyor mechanism 421, a second belt conveyor mechanism 422, a third belt conveyor mechanism 423, a fourth belt conveyor mechanism 424, and a fifth belt conveyor mechanism 425. These multiple belt conveyor mechanisms are evenly spaced and parallel to each other along the moving direction of the slide table 31, with the conveying direction parallel to that of the upper-level belt conveyor mechanism 41. The first to fifth belt conveyor mechanisms correspond to different electrode plate weight ranges. The control device is located inside a housing under the base platform 11 and is used to control each part to complete its respective work.

[0037] The specific structure of each of the above parts is as follows:

[0038] The base platform 11 includes a wide-body platform 111 and a narrow-body platform 112. The wide-body platform 111, located near the lower-level belt conveyor mechanism 42, has through holes on its surface. The narrow-body platform 112, located near the upper-level belt conveyor mechanism 41, is fixedly connected in a "T" shape. The electrode plate buffer device is installed on the upper end of the narrow-body platform. The electrode plate buffer device 13 includes a first side support frame 131, a first auxiliary support frame 132, a first conveyor roller group 133, and a rotation damper 134. To achieve the electrode plate picking action, the first side support frame 131 is a single-sided frame with two support columns at its bottom end, which are fixedly connected to the upper end of the narrow-body platform 112 near one side. To increase its stability, first auxiliary support frames 132 are installed on both sides of its support columns. The first conveyor roller group 133 includes four cylindrical rollers of the same size, evenly spaced horizontally. The inner ring of the rotation damper 134 is fixedly connected to one end of the cylindrical rollers, and the outer ring is fixedly connected to the first side support 131, so that the four cylindrical rollers are cantilevered on one side of the side support. When the electrode plate is conveyed to the electrode plate conveyor roller 133 by the upper belt conveyor mechanism 41, it has a certain initial velocity. To facilitate subsequent operations on the electrode plate, the first conveyor roller group decelerates the electrode plate, causing it to stop in the middle of the first conveyor roller group 133 under the action of the rotation damper 134. To prevent the electrode plate from tilting, electrode plate retaining rings 1331 are installed at the outer ends of the four cylindrical rollers. A first sensor 1311 is installed on the outer side of the top of the side support 131 to detect the position of the electrode plate. The foot cup 12 is threadedly connected to the bottom of the base platform 11 and contacts the ground. Its height can be adjusted to adapt to uneven ground, thereby enhancing the stability of the base platform 11.

[0039] The slide table conveying device 32 includes a rodless cylinder 321, a slide table conveying guide rail 322, a slide table conveying slider 323, and a distance sensor 324. The cylinder body of the rodless cylinder 321 is fixedly installed at the center of the upper surface of the wide-body platform 111, and is arranged along the long side of the base platform (perpendicular to the conveying direction of the electrode plate). The slider of the rodless cylinder 321 is fixedly connected to the bottom surface of the slide table 31, providing power for the slide table to achieve reciprocating linear motion perpendicular to the electrode plate conveying direction. Two slide table conveying guide rails 322 are fixedly installed on the upper surface of the wide-body platform 111 and located on both sides of the rodless cylinder installation position, and are parallel to the rodless cylinder 321. The slide platform has four sliding blocks. Two are slidably connected to one side of the slide platform guide rail, and the other two are slidably connected to the other side. The upper surfaces of the four sliding blocks are fixedly connected to the four corners of the slide platform 31, thereby reducing the force on the rodless cylinder 321 and ensuring the orientation and stability of the slide platform 31 during movement. In operation, the control device drives the rodless cylinder 321 to move the slide platform 41 along the slide platform guide rail 322 based on the electrode plate weighing result, thereby controlling the slide platform 41 to move to a certain lower belt conveyor mechanism 42 corresponding to the corresponding electrode plate weight range. A distance sensor 324 is installed at one end of the wide-body platform 111 to detect the position of the slide platform 41. When the slide platform 41 moves to the designated position, the distance sensor 324 transmits the position information to the control device, which then controls the rodless cylinder 321 to stop moving to the current position, thereby preventing the electrode plate from falling due to inaccurate positioning of the slide platform 41.

[0040] The material weighing device 33 includes a first rotating rod 331, a second rotating rod 332, a third rotating rod 333, a rotating fixed rod 334, a weighing block 335, a weighing support plate 336, a weighing sensor 337, a gasket 338, a rotary bearing 339, a weighing sensor support plate 3310, and a rotating rod power transmission device 3311. The rotating fixed rod 334 is vertically fixedly connected to one corner of the upper end of the slide table 31. An upper rotating shaft and a lower rotating shaft are mounted on the rotating fixed rod. One end of the first rotating rod is fixedly connected to one end of the upper rotating shaft, and the other end of the first rotating rod is rotatably connected to the upper end of the third rotating rod 333 via the rotary bearing 339. One end of the second rotating rod is fixedly connected to one end of the lower rotating shaft, and the other end of the second rotating rod is rotatably connected to the lower end of the third rotating rod 333 via the rotary bearing 339. The load cell support plate 3310 is welded to the middle of the third rotating rod. To ensure its stability, an auxiliary support rib is welded below. Both load cells 337 are cantilever beam type sensors, requiring one end to be fixed and the other end to be loaded during use. Therefore, one side of each load cell 337 is symmetrically fixed on the upper end of the load cell support plate 3310. A gasket is installed on the upper end of the other side of each load cell 337, and a weighing block 335 is installed on the upper end of the gasket. Long screws are used to connect them. When the weighing block 335 is subjected to downward gravity, one end of the load cell experiences strain, thus accurately measuring the weight of the electrode plate. The weighing support plate 336 is a sheet-like plate. By increasing the contact area with the electrode plate, damage to the electrode plate surface is reduced. Four weighing support plates 336 are evenly spaced along the length of the weighing block 335, with one end fixedly connected to the weighing block 335. To ensure its stability, an auxiliary support rib is welded below. The outer end of the weighing tray 336 is equipped with an electrode plate baffle 3361 to prevent the electrode plates from falling during the conveying process. The first rotating rod 331, the second rotating rod 332, the third rotating rod 333, and the rotating fixed rod 334 form a parallel four-bar linkage mechanism. The rotation of the rotating rods enables the weighing of the electrode plates to be completed simultaneously with the picking and placing of the electrode plates, maintaining the accuracy of the electrode plate weighing without reducing the conveying efficiency of the electrode plates or damaging the surface quality of the electrode plates.

[0041] The rotating rod power transmission device 3311 employs a gear transmission mechanism, including a first bevel gear 33111, a second bevel gear 33112, a third bevel gear 33113, a fourth bevel gear 33114, a fifth bevel gear 33115, a sixth bevel gear 33116, a seventh bevel gear 33117, an eighth bevel gear 33118, a first motor 33119, a transmission rod fixing block 33120, a transmission rod fixing strip 33121, a first encapsulation cover 33122, a second encapsulation cover 33123, a first transmission rod 33124, a second transmission rod 33125, and a transmission rod bearing 33126. The first bevel gear 33111 is fixedly mounted on the other end of the upper rotating shaft. The first transmission rod is vertically arranged and is mounted on two vertically arranged transmission rod fixing blocks via two vertically arranged transmission rod bearings 33126. These two transmission rod fixing blocks are fixedly connected to the side of the rotating fixed rod away from the weighing plate. The second bevel gear 33112 is fixedly connected to the top of the first transmission rod 33124 and meshes with the first bevel gear 33111. The third bevel gear 33113 is fixedly installed at the other end of the lower rotating shaft and meshes with the fourth bevel gear 33114, which is fixedly installed on the first transmission rod 33124.

The second transmission rod is horizontally oriented and is mounted on two horizontally oriented transmission rod fixing blocks via two transmission rod bearings. These two transmission rod fixing blocks are fixedly installed on a transmission rod fixing strip. The transmission rod fixing strip 33121 is inverted "L" shape and is fixedly installed on the slide table 31. The transmission rod fixing strip and the rotating fixing rod 334 can be integrally formed. The seventh bevel gear 33117 is fixedly mounted on the other end of the second transmission rod 33125 and meshes with the eighth bevel gear 33118. The eighth bevel gear 33118 is fixedly mounted on the output shaft of the first motor 33119, and the first motor 33119 is fixedly mounted on the slide table 31, thereby realizing synchronous power transmission between the first rotating rod 331 and the second rotating rod 332. The first encapsulation cover 33122 is L-shaped and is fixedly mounted on the rotating fixed rod 334 and the slide table 31 by bolts. The second encapsulation cover 33123 is fixedly mounted on the end of the first motor 33119 by bolts, realizing dustproof sealing protection for the rotating rod power transmission device 3311.

[0042] The electrode plate conveying device 34 includes a second side support frame 341, a second auxiliary support frame 342, a second conveyor roller group 343, a conveyor roller bearing 344, a conveyor roller power roller 345, a power conveyor belt 346, a second motor 347, a power conveyor belt tensioning device 348, a third sealing cover 349, and a fourth sealing cover 350. To enable the setting action performed after the electrode plate weighing operation is completed, the second side support frame 341 is a single-sided frame. Four through holes are evenly distributed at the top of the second side support frame 341, and its bottom is fixedly installed on one side of the slide table 31. To increase its stability, second auxiliary support frames 342 are installed on both sides of its connection point.

[0043] The outer rings of the four conveyor roller bearings 344 are respectively fixedly installed in four through holes on the second side support 341. The second conveyor roller group consists of four conveyor rollers. Each of the four conveyor rollers is a cylindrical stepped roller, with its smaller diameter end fixedly connected to the inner ring of each of the four conveyor roller bearings 344, and extending a certain length outward from the bearings 344, and fixedly connected to each of the four conveyor roller drive rollers 345. The larger diameter ends of the four conveyor rollers extend a certain length outward, forming a conveying support portion that contacts the electrode plate. To prevent the electrode plate from becoming misaligned, an electrode plate retaining ring 1331 is installed at the end of each conveyor roller. The second motor 347 drives the four conveyor roller drive rollers 345 via a power transmission belt 346, thereby providing power to the conveyor rollers 343 and realizing the conveying of the electrode plate. A second sensor 3411 is installed on the outer side of the upper end of the second side support 341 to detect the position of the electrode plate. The power transmission belt tensioning device 348 includes a tensioning roller 3481, a tensioning block 3482, and a tensioning block locking pin 3483. A sliding through hole is provided on the side of the second side support 341, along which the tensioning block 3482 can slide. Positioning holes are evenly distributed on the tensioning block 3482, and a rotating shaft is welded to one end, connected to the tensioning roller 3481 via a bearing. The tensioning roller 3481 is in close contact with the inner side of the power transmission belt 346. By adjusting the position of the tensioning block 3482, the tensioning roller 3481 can be moved, thereby controlling the tension of the power transmission belt 346 and preventing slippage. When the tensioning block 3482 is in a suitable position, it can be fixed in that position by pushing the tensioning block locking pin 3483 to engage with the positioning hole. The third encapsulation cover 349 is fixed to the outside of the second side stand 341 by bolts, and the fourth encapsulation cover 350 is fixed to its inside by bolts, thereby achieving dustproof and sealed protection for the electrode plate conveying device 34.

[0044] The human-computer interaction part 2 includes a connecting rod part 21, a display panel 22, and an adjustment armrest 23. The connecting rod part 21 includes a first connecting rod 211, a second connecting rod 212, a third connecting rod 213, and a fourth connecting rod 214. The first connecting rod 211 is fixedly connected to the side of the base platform 11 and extends outward in a direction perpendicular to the edge of the base platform 11. A support column is fixedly connected below it to ensure the stability of the human-computer interaction part 2. One end of the second connecting rod 212 is hinged to the first connecting rod 211, and the other end is hinged to the third connecting rod 213. The other end of the third connecting rod 213 is hinged to the fourth connecting rod 214, and the other end of the fourth connecting rod 214 is welded and fixed to the display panel 22. The second connecting rod 212 and the third connecting rod 213 can rotate about the hinge point in a plane perpendicular to the ground, and the fourth connecting rod 214 can rotate about the hinge point in a plane parallel to the ground. The adjustable armrests 23 are located on both sides of the display panel, allowing for position adjustment of the display panel 22 to facilitate operator use. Each of the three hinge points has adjustable damping to maintain relative stillness between the connecting rods and the display panel 22 without requiring posture adjustments, thus achieving the positioning of the display panel 22.

[0045] The working process of this invention is as follows:

[0046] In the initial state, the second side support 341 is flush with the first auxiliary support 132, and the first rotating rod 331 and the second rotating rod 332 are both in a vertically downward position;

[0047] After the electrode plate passes through the previous process, it is conveyed to the upper belt conveyor mechanism 41. Under the action of the rotation damper 134, the electrode plate is quickly stopped at the middle position of the first conveyor roller group 133.

[0048] The first sensor 1311 detects the position of the electrode plate, and the control device controls the first motor 33119 to start. The motor drives the parallel four-bar linkage composed of the first rotating rod 331, the second rotating rod 332, the third rotating rod 333 and the rotating fixed rod 334 to rotate through the rotating rod power transmission device 3311. This causes the weighing pallet 336 to move in a circular motion toward the first auxiliary support frame 132. After passing the first electrode plate buffer roller group 133, the weighing pallet 336 lifts the electrode plate. When the first rotating rod 331 and the second rotating rod 332 are both raised to the vertically upward position, the first motor 33119 is turned off. At this time, the control device obtains the weight of the electrode plate through the weighing sensor 337 and determines its weight range.

[0049] The control device controls the rodless cylinder 321 to drive the slide table 31 to move rapidly along the slide table conveyor rail 322 to the lower belt conveyor mechanism 42 corresponding to the weight range of the electrode plate. When the distance sensor 324 receives the position signal, the control device controls the rodless cylinder 321 to stop moving.

[0050] The first motor 33119 restarts and drives the parallel four-bar linkage composed of the first rotating rod 331, the second rotating rod 332, the third rotating rod 333 and the rotating fixed rod 334 to rotate through the rotating rod power transmission device 3311. This causes the weighing pallet 336 to continue to move in a circular motion in the original direction of motion. After passing the second conveyor roller group 343, the weighing pallet 336 places the pole plate on the four conveyor rollers. When the first rotating rod 331 and the second rotating rod 332 are both lowered to their initial positions, the first motor 33119 is turned off.

[0051] The second sensor 3411 detects the position of the electrode plate, and the control device controls the second motor 347 to start, which drives the conveyor roller to rotate through the power conveyor belt 346, thereby conveying the electrode plate to the lower belt conveyor mechanism 42.

[0052] Then, the control device controls the rodless cylinder 321 to drive the slide table 31 to move quickly along the slide table conveyor rail 322 to the initial position, and continue to weigh and sort the next electrode plate.

[0053] Although embodiments and drawings of the present invention have been disclosed for illustrative purposes, those skilled in the art will understand that various substitutions, alterations and modifications are possible without departing from the spirit and scope of the present invention and the appended claims. Therefore, the scope of the present invention is not limited to the contents disclosed in the embodiments and drawings.
