Description

Technical Field

[0001] The present invention relates to the technical field of battery box stamping production, and in particular to a stamping forming device for battery box production. Background Art

[0002] In the production of battery boxes, traditional stamping equipment has low positioning accuracy during the loading process, and it is difficult to adapt to aluminum plates of different specifications, resulting in position deviation of the aluminum plate in subsequent processes, affecting the stamping quality. Surface treatment is an important step to improve the quality of aluminum plates, but the surface treatment function of existing equipment is weak. The detection means are not accurate enough, and it is difficult to fully and quickly detect scratches and defects on the surface of the aluminum plate. The repair device has low efficiency and poor accuracy. The repair effect is not ideal for shallow defects, and it cannot effectively handle deeper defects. The entire aluminum plate can only be discarded, resulting in a waste of materials. Or, if the aluminum plate is not repaired and the stamping operation is directly carried out, it will cause product quality problems, which will affect the yield rate.

[0003] During the cutting and conveying stage of aluminum plates, the conveying mechanism is not designed properly and cannot accurately distinguish good products from waste materials, which leads to chaotic production processes and reduced production efficiency.

DETAILED DESCRIPTION

[0032] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0033] like Figure 1-10The stamping forming equipment shown in the figure for battery box production includes a stamping device and an aluminum plate feeding mechanism installed at the feeding port of the stamping device. The aluminum plate feeding mechanism includes a feeding mechanism 1, an adjustable positioning mechanism 2, a leveling mechanism 3, a surface treatment mechanism 4 and a cutting and conveying mechanism 5 which are arranged in sequence along the transmission direction of the aluminum plate. The surface treatment mechanism 4 includes a grinding component 6, a hot pressing repair component 7, and two groups of laser scanners 8, a first displacement component 9, a second displacement component 10 and a closing drive component 11. The two groups of laser scanners 8 are installed at the upper and lower ends of the leveling mechanism 3. The output direction of the first displacement component 9 is consistent with the transmission direction of the aluminum plate. The first displacement component 9 is provided with A first mounting frame 12 is used to mount a grinding component 6 or a hot press repair component 7, the second displacement component 10 is mounted on the first mounting frame 12 and the transmission direction is perpendicular to the transmission direction of the first displacement component 9, the closing drive component 11 is mounted at the output end of the second displacement component 10, the grinding component 6 includes a grinding wheel 13, the hot press repair component 7 includes a hot press repair head 14 for repairing surface scratches of the aluminum plate, the grinding component 6 and the hot press repair component 7 are respectively mounted on the output ends of the two groups of closing drive components 11, the cutting and conveying mechanism 5 includes a cutting knife 15, an aluminum plate transmission component 16 and a waste carrying chamber 17, and the output direction of the aluminum plate transmission component 16 is consistent with the aluminum plate transmission direction.

[0034] During the stamping process of battery box production, the aluminum plate is first loaded by the loading mechanism 1. After loading, the aluminum plate enters the adjustable positioning mechanism 2, and the positioned aluminum plate then reaches the leveling mechanism 3 to optimize the flatness of the aluminum plate and prepare for subsequent surface treatment. In the surface treatment mechanism 4, two groups of laser scanners 8 detect scratches, flaws and other defects on the surface of the aluminum plate in a timely manner. When the defect is detected, the first displacement component 9 moves along the transmission direction of the aluminum plate according to the position of the defect, and can move synchronously with the aluminum plate to accurately transport the grinding component 6 or the hot pressing repair component 7 installed on the first mounting frame 12 to the defect position. The second displacement component 10 is adjusted in a direction perpendicular to the transmission direction of the first displacement component 9 to further accurately align the defect position. The closing drive component 11 is actuated to make the grinding wheel 13 of the grinding component 6 or the hot pressing repair head 14 of the hot pressing repair component 7 approach the surface of the aluminum plate for treatment. For shallow scratches and flaws, the hot pressing repair head 14 re-integrates the material on the surface of the aluminum plate by heating and applying pressure to restore the flatness. For deeper defects, hot pressing repair is first performed, and then fine grinding is performed by the grinding wheel 13 to remove the repair marks and make the surface smoother and flatter.

[0035] The aluminum plate after surface treatment enters the cutting and conveying mechanism 5, the cutting knife 15 cuts the aluminum plate into a suitable size, and the aluminum plate transmission component 16 conveys the cut aluminum plate to the next process along the transmission direction, and the waste generated in the cutting process falls into the waste carrying chamber 17 directly below. The waste is generated when the damaged part of the aluminum plate is directly removed when the aluminum plate cannot be repaired in a short time.

[0036] The second displacement assembly 10 includes a synchronous sliding frame 18, a first rotation driver 19, a first threaded rod 20 and a synchronous belt 21. The synchronous sliding frame 18 has two (eg Fig.10 As shown), two synchronous sliding frames 18 are symmetrically arranged at the upper and lower ends of the aluminum plate, two first threaded rods 20 are provided, and both ends of the first threaded rods 20 can be rotatably installed on the first mounting frame 12, one end of the first rotation driver 19 is fixedly connected to the end of one of the first threaded rods 20, the two first threaded rods 20 are respectively threadedly connected to the two synchronous sliding frames 18, the synchronous sliding frame 18 is horizontally slidably connected to the first mounting frame 12, the grinding assembly 6 and the hot pressing repair assembly 7 are respectively installed on the synchronous sliding frames 18 of the two groups of second displacement assemblies 10, and the two ends of the synchronous belt 21 are respectively transmission-connected to the two first threaded rods 20.

[0037] In the second displacement assembly 10 of the present invention, two synchronous sliding frames 18 are provided, which are symmetrically arranged at the upper and lower ends of the aluminum plate. Each synchronous sliding frame 18 establishes a horizontal sliding connection with the first mounting frame 12 to ensure that the synchronous sliding frame 18 can stably move along a predetermined horizontal direction. When the first rotary driver 19 is started, it can drive the first threaded rod 20 to rotate. Since the two first threaded rods 20 are respectively threadedly connected to the two synchronous sliding frames 18, and are linked by a synchronous belt 21. When the first rotary driver 19 drives one of the first threaded rods 20 to rotate, the other first threaded rod 20 will rotate synchronously and in the same direction through the transmission action of the synchronous belt 21, and the synchronous sliding frame 18 can accurately control the direction and distance of movement, so that the grinding assembly 6 or the hot press repair assembly 7 can be accurately moved to the position on the surface of the aluminum plate that needs to be processed.

[0038] The closing drive assembly 11 includes a first linear drive 22 and two lifting plates 23 and a transmission plate 24, each of which is provided with two lifting plates 23. The two lifting plates 23 are both arranged horizontally, and the length direction of the lifting plates 23 is consistent with the width direction of the aluminum plate. The two lifting plates 23 are respectively arranged on the upper and lower synchronous sliding frames 18 in the same group of second displacement components 10. The first linear drive 22 is vertically fixedly installed on the first mounting frame 12, and the output end of the first linear drive 22 is fixedly connected to one of the lifting plates 23. The lifting plate 23 and the synchronous sliding frame 18 are slidably arranged in the vertical direction. The two transmission plates 24 are vertically arranged at both ends of the first mounting frame 12. The transmission plate 24 is hinged to the same end of the two lifting plates 23 through a hinge rod 25. The transmission plate 24 and the first mounting frame 12 slide in cooperation in the horizontal direction. A tension spring 26 is provided between the transmission plate 24 and the first mounting frame 12, and the two ends of the tension spring 26 are respectively fixedly connected to the transmission plate 24 and the first mounting frame 12.

[0039] When the first linear drive 22 is started, the telescopic movement of the output end directly acts on the lifting plate 23, causing it to slide in the vertical direction relative to the synchronous sliding frame 18. When one lifting plate 23 moves vertically under the action of the first linear drive 22, the hinge rod 25 will drive the other lifting plate 23 to move synchronously. The tension spring 26 arranged between the transmission plate 24 and the first mounting frame 12 has two ends fixedly connected to the transmission plate 24 and the first mounting frame 12 respectively. The tension spring 26 plays a role of balancing and resetting in the system. When the first linear drive 22 pushes the lifting plate 23 to move, the tension spring 26 is stretched; when the thrust of the first linear drive 22 disappears, the contraction force of the tension spring 26 will assist the transmission plate 24 and the lifting plate 23 to return to the initial position. This method enables the upper and lower lifting plates 23 to move closer to each other during operation, that is, to move close to the surface of the aluminum plate in the working state, driving the grinding wheel 13 or the hot pressing repair head 14 carried thereon to approach the surface of the aluminum plate, so that it can process the surface of the aluminum plate.

[0040] There are two groups of grinding assemblies 6, and the two groups of grinding assemblies 6 are installed on the output ends of the same second displacement assembly 10. The two groups of grinding assemblies 6 are arranged in sequence along the transportation direction of the aluminum plate. The grinding wheels 13 in the two groups of grinding assemblies 6 are respectively located above and below the aluminum plate. The grinding assembly 6 also includes a first bearing plate 27 and a second rotation driver 28. The grinding wheel 13 can be rotatably installed on the synchronous sliding frame 18. The second rotation driver 28 is slidably set on the synchronous sliding frame 18. The output end of the second rotation driver 28 is transmission connected to the grinding wheel 13, and the lifting plate 23 is transmission connected to the grinding wheel 13. The first bearing plate 27 is located at the end of the aluminum plate away from the grinding wheel 13. An unpowered sliding belt 29 is provided on the first bearing plate 27, and an internal support frame is provided inside the unpowered sliding belt 29. The first bearing plate 27 is slidably set on the synchronous sliding frame 18, and the lifting plate 23 is transmission connected to the first bearing plate 27.

[0041] The grinding components 6 of the present invention are arranged in two groups, which are respectively located above and below the aluminum plate. The purpose of such a layout is that when the aluminum plate continues to run and scratches are detected by the laser scanner 8, no matter which surface the scratches are located on, the two groups of grinding components 6 can quickly grind them. This design makes it unnecessary to set up two independent systems for the equipment to process the scratches on the upper and lower surfaces of the aluminum plate respectively, which not only improves the grinding efficiency, but also saves the floor space of the equipment.

[0042] In the grinding assembly 6, an unpowered sliding belt 29 is provided. The unpowered sliding belt 29 is mounted on the first bearing plate 27, and an internal support frame is provided inside to enhance the support strength. During the continuous grinding process of the aluminum plate, even if the synchronous sliding frame 18 slides, the unpowered sliding belt 29 can still provide stable support for the aluminum plate, ensuring that the aluminum plate does not shift in position due to sliding, thereby ensuring the accuracy of the grinding position. There is appropriate friction between the unpowered sliding belt 29 and the surface of the aluminum plate, which can not only ensure the smooth movement of the aluminum plate, but also prevent it from shifting in the horizontal direction. At the same time, the sliding action of the unpowered sliding belt 29 is consistent with the sliding direction of the synchronous sliding frame 18, and will not cause additional pressure or damage to the aluminum plate.

[0043] Compared with the prior art, it may be necessary to set up separate processing systems for the scratches on the upper and lower surfaces of the aluminum plate, which is not only inefficient but also takes up a lot of space. The two sets of grinding components 6 of the present invention can simultaneously deal with the scratches on the upper and lower surfaces of the aluminum plate, achieve rapid processing, and greatly improve production efficiency. The design of the unpowered sliding belt 29 effectively solves the problem of position stability of the aluminum plate during the running grinding process, avoids grinding errors caused by position offset, and further improves the grinding quality and accuracy.

[0044] The hot pressing repair component 7 also includes a second linear drive 30, a sliding seat 31 and an elastic telescopic rod 32. The sliding seat 31 is vertically slidably set on the synchronous sliding frame 18. The sliding seat 31 is slidably set along the length direction of the lifting plate 23. The second linear drive 30 is fixedly installed on the sliding seat 31. The hot pressing repair head 14 is located on the side of the sliding seat 31 close to the aluminum plate. The hot pressing repair head 14 is connected to the sliding seat 31 through the elastic telescopic rod 32. The output end of the first rotary drive 19 is transmission-connected to the hot pressing repair head 14.

[0045] During operation, when it is detected that there is an area on the surface of the aluminum plate that needs hot press repair, the hot press repair head 14 is first driven to contact the aluminum plate through the lifting plate 23, and the second linear drive 30 is activated, and its output end pushes the hot press repair head 14 to apply pressure to the surface of the aluminum plate. The elastic telescopic rod 32 plays a buffering and adaptive role in this process, and can adapt to the slight unevenness of the surface of the aluminum plate, ensuring that the hot press repair head 14 is in uniform contact with the surface of the aluminum plate, applying stable pressure and heat, and achieving effective repair.

[0046] Compared with the prior art, the traditional hot press repair device may not be flexible enough in position adjustment, it is difficult to accurately align the repair part, and lacks an effective buffer mechanism, which easily causes excessive pressure on the aluminum plate or uneven repair effect. The hot press repair assembly 7 of the present invention significantly improves the accuracy, uniformity and reliability of hot press repair through the multi-directional sliding of the sliding seat 31, the precise driving of the second linear drive 30 and the buffering self-adaptation of the elastic telescopic rod 32.

[0047] The aluminum plate transmission assembly 16 includes a third displacement assembly 33, a second supporting plate 34, a side conveying device 35 and a center conveying device 36. The side conveying device 35 and the center conveying device 36 are both ball conveyor belts. The side conveying device 35 is arranged at both ends of the center conveying device 36. The third displacement assembly 33 is installed below the center conveying device 36. The output direction of the third displacement assembly 33 is consistent with the aluminum plate transmission direction. The center conveying device 36 is fixedly installed on the output end of the third displacement assembly 33. The cutting knife 15 is located directly above the second supporting plate 34. The second supporting plate 34 is provided with a cutting groove 37.

[0048] In the cutting and conveying mechanism 5, the side conveying device 35 and the center conveying device 36 are both ball conveyor belts. The side conveying device 35 is arranged at both ends of the center conveying device 36, and together they construct the transmission path of the aluminum plate. The third displacement assembly 33 is installed below the center conveying device 36, and its output direction is consistent with the transmission direction of the aluminum plate. The center conveying device 36 is fixedly installed on the output end of the third displacement assembly 33. When the aluminum plate is cut, if it is a qualified aluminum plate, the center conveying device 36 is driven by the third displacement assembly 33 to accurately convey it to the feed end of the stamping device for subsequent stamping processing, and the waste carrying chamber 17 is arranged below the aluminum plate conveying route. When the cutting produces waste, the third displacement assembly 33 controls the displacement distance of the center conveying device 36 to shorten. At this time, the waste on the center conveying device 36 cannot reach the feed end of the stamping device due to insufficient conveying distance, and thus falls into the waste carrying chamber 17 below.

[0049] In actual work, this design can automatically distinguish qualified aluminum plates from waste materials and realize accurate classification and transportation. Compared with the traditional cutting and conveying mechanism 5, it may not be able to effectively distinguish and process qualified products and waste materials separately, resulting in confusion in the production process or increasing the workload of subsequent screening. The present invention improves production efficiency, reduces the cost and error rate of manual screening, and realizes an automated and efficient production process by accurately controlling the displacement of the central conveying device 36.

[0050] The leveling mechanism 3 includes a leveling frame 38 and a feeding assembly 39 . A plurality of staggered leveling rollers 40 are provided in the leveling frame 38 . The feeding assembly 39 is installed at the end of the leveling frame 38 .

[0051] The feeding assembly 39 includes two rotatable feeding rollers 41 , and a plurality of rubber friction strips 42 are provided in an annular shape on the outer side wall of the feeding roller 41 and arranged along the axis direction of the feeding roller 41 .

[0052] After the aluminum plate is leveled, it enters the feeding assembly 39. The feeding roller 41 rotates, and the friction between the rubber friction strip 42 and the aluminum plate stably feeds the leveled aluminum plate forward. After the width and thickness of the aluminum plate are changed, the existing feeding roller 41 is prone to problems such as aluminum plate slippage and position deviation during the feeding process. In the present invention, the staggered leveling rollers 40 can level the aluminum plate more comprehensively and effectively, improve the leveling quality, and the rubber friction strip 42 on the feeding roller 41 increases the friction between the aluminum plate and the feeding roller 41, ensuring the stability and accuracy of the feeding, and reducing the position deviation and speed fluctuation of the aluminum plate during the conveying process.

[0053] The adjustable positioning mechanism 2 includes a bidirectional screw slide 43, a positioning roller 51, a central bearing plate 45, a sliding mounting frame 46, a connecting column 47, a slider 48 and a spring 49. The bidirectional screw slide 43 is horizontally arranged between the feeding mechanism 1 and the leveling mechanism 3. The output direction of the bidirectional screw slide 43 is arranged perpendicular to the transportation direction of the aluminum plate (such as Figure 8 As shown in the figure, the bidirectional screw slide 43 is provided with two symmetrical output ends, the sliding mounting frame 46 is provided with two and fixedly mounted on the two output ends of the bidirectional screw slide 43 respectively, the central bearing plate 45 is arranged in the middle of the bidirectional screw slide 43, and each sliding mounting frame 46 is provided with a plurality of connecting columns 47, sliders 48 and springs 49 in sequence along the transmission direction of the aluminum plate. The slider 48 is slidably arranged with the sliding mounting frame 46, and the two ends of the spring 49 are fixedly connected with the slider 48 and the sliding mounting frame 46 respectively. The spring 49 is located on the side of the slider 48 away from the central bearing plate 45. The connecting column 47 is rotatably mounted on the slider 48 through a bearing, and the positioning roller 51 is threadedly connected with the connecting column 47.

[0054] The connecting column 47 is rotatably mounted on the slider 48 through a bearing, and the positioning roller 51 is threadedly connected to the connecting column 47. During operation, according to the specifications and position information of the aluminum plate, the bidirectional screw slide 43 moves, driving the two sliding mounting frames 46 to move closer or farther from each other, thereby adjusting the initial position of the positioning roller 51. When the aluminum plate enters the positioning area, if the aluminum plate contacts and pushes the positioning roller 51, the slider 48 will slide on the sliding mounting frame 46, compressing the spring 49. The elastic force of the spring 49 will cause the positioning roller 51 to apply a certain pressure to the aluminum plate, thereby achieving fine-tuning and stable clamping of the aluminum plate position. The threaded connection between the connecting column 47 and the positioning roller 51 is convenient for replacing positioning rollers 51 of different specifications as needed. Compared with the positioning mechanism in the prior art, the traditional positioning device may not be flexible enough to adjust and has insufficient precision, and is difficult to adapt to aluminum plates of different specifications. The adjustable positioning mechanism 2 of the present invention realizes a wide range of position adjustment through the bidirectional screw slide 43, and realizes slight adaptive adjustment in combination with the design of the spring 49 and the slider 48, thereby improving the positioning accuracy and flexibility, and can better adapt to aluminum plates of various sizes and shapes, ensuring that the aluminum plate is accurately positioned before entering the subsequent process.

[0055] A V-shaped annular groove 50 with a V-shaped cross section is provided on the positioning roller 51 , and an alloy anti-cutting ring is provided in the V-shaped annular groove 50 .

[0056] During operation, when the aluminum plate contacts the positioning roller 51, the edge of the aluminum plate is embedded in the V-shaped ring groove 50, and the alloy anti-cutting ring is in direct contact with the edge of the aluminum plate. Due to the presence of the alloy anti-cutting ring, the friction damage between the aluminum plate and the positioning roller 51 is reduced, and the accuracy and stability of positioning are also guaranteed.

[0057] The overall working principle of the present invention:

[0058] During the stamping process of the battery box, the aluminum plate is first transported from the feeding mechanism 1 to the adjustable positioning mechanism 2, and the bidirectional screw slide 43 drives the sliding mounting frame 46 to preliminarily adjust the position of the positioning roller 51. When the aluminum plate contacts the positioning roller 51, the slider 48 slides on the sliding mounting frame 46 and compresses the spring 49. The elastic force of the spring 49 causes the positioning roller 51 to apply a certain pressure to the aluminum plate, thereby achieving precise fine-tuning and stable clamping of the aluminum plate. The threaded connection between the connecting column 47 and the positioning roller 51 is convenient for replacing positioning rollers 51 of different specifications as needed to adapt to aluminum plates of various sizes and shapes.

[0059] The aluminum plate that has been precisely positioned arrives at the leveling mechanism 3. After being shaped by the leveling mechanism 3, it is conveyed to the surface treatment mechanism 4. The scratches, blemishes and other defects on the upper and lower surfaces of the aluminum plate are detected by the laser scanner 8. Then, the second displacement component 10 is actuated to move the hot press repair component 7 to the position to be repaired. When the wound site moves to the hot press repair component 7 along with the transmission of the aluminum plate, the first displacement component 9 drives the hot press repair component 7 to move synchronously with the wound site in order to perform the repair operation. For shallower and easier-to-repair defects, the hot press repair component 7 first re-integrates the surface material of the aluminum plate by heating and applying pressure, and then the polishing component 6 performs fine polishing to remove the repair marks and restore the surface of the aluminum plate to be flat and smooth. For deeper defects that take a longer time to repair, the aluminum plate is no longer repaired and directly enters the subsequent cutting and conveying mechanism 5.

[0060] When the defects on the surface of the aluminum plate are detected by the laser scanner 8, and the first displacement assembly 9 and the second displacement assembly 10 move the hot press repair assembly 7 or the polishing assembly 6 to the approximate position, the closing drive assembly 11 starts to function. By driving the lifting plate 23 to move, the hot press repair assembly 7 or the polishing assembly 6 installed on the lifting plate 23 moves closer to or away from the surface of the aluminum plate, thereby completing the processing of the surface of the aluminum plate.

[0061] When hot pressing marks are removed, the second linear drive 30 pushes the hot pressing repair head 14 to move toward the surface of the aluminum plate, so that the hot pressing repair head 14 is in close contact with the surface of the aluminum plate and a certain pressure is applied. The rotary drive is started to drive the grinding wheel 13 to rotate at a high speed. At the same time, the lifting plate 23 drives the grinding wheel 13 to approach the surface of the aluminum plate, so that the rotating grinding wheel 13 is in contact with the surface of the aluminum plate, and through friction and grinding, the traces of the aluminum plate surface after hot pressing repair or the uneven parts after the repair of deeper defects are removed, so that the surface of the aluminum plate is smoother and flatter. The aluminum plate (including good products and waste with deeper defects) is transported by the cutting and conveying mechanism 5. After the aluminum plate is cut, if it is a good product, the third displacement component 33 drives the central conveying device 36 to accurately convey it to the feeding end of the stamping device; if it is a waste with deeper defects, the third displacement component 33 controls the central conveying device 36 to convey it to the waste carrying chamber 17. The cutting knife 15 located directly above the support plate cooperates with the cutting groove 37 set on the support plate to complete the cutting work of the aluminum plate.

[0062] The above embodiments only express one or several implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
