Description

Technical Field

[0001] This application relates to the field of automated conveying equipment technology, and in particular to a continuous and precise positioning feeding conveyor line for aluminum plates. Background Technology

[0002] In automated aluminum sheet processing production lines (such as punching, bending, cutting, and welding), aluminum sheets need to be transported between different workstations and precisely positioned at each station to ensure processing quality and product consistency. In zinc electrolysis production, the cathode aluminum sheet undergoes multiple processing steps, including punching and sinking. The limited opening height between the upper and lower dies of the punching and sinking dies places stringent requirements on the aluminum sheet feeding and unloading methods and the accuracy of workstation positioning. The original design used a hydraulic pushing device to transfer aluminum plates between workstations, but in actual use, the following prominent problems were exposed: the aluminum plates were prone to skew during the feeding and unloading process, resulting in edge damage or even plate damage, affecting the product qualification rate; due to the lack of a precise positioning mechanism, the aluminum plates often could not be accurately delivered to the predetermined processing position, often requiring two operators to assist in pushing and pulling and manually positioning near the mold, which posed a high safety risk, high labor intensity, and low production efficiency; in addition, the traditional hydraulic pushing mechanism has a long push rod, and its installation position usually requires a long distance of space, which is not conducive to the utilization of production site space.

[0003] While some existing plate chain conveyor lines can achieve continuous material transport, most of them lack the ability to accurately position workpieces in both longitudinal and transverse directions at the processing station. In particular, it is difficult to complete the front-to-back and left-to-right position correction of aluminum plates in a narrow mold opening space, and the positioning accuracy is difficult to meet the process requirements of punching, sinking, etc.

[0004] Therefore, there is an urgent need to develop a continuous and precise aluminum plate feeding and conveying line that is stable in operation, accurate in positioning, compact in overall height, fully adaptable to installation in small spaces, capable of continuous conveying of aluminum plates, and capable of simultaneous and precise positioning at multiple workstations. Summary of the Invention

[0011] Optionally, in some embodiments, the aluminum plate processing station conveying platform 16 includes an aluminum plate processing station conveying platform support plate 161 and an aluminum plate processing station processing platform 162 for aluminum plate processing, which is disposed on the aluminum plate processing station conveying platform support plate 161. Feeding conveying platform track supports 151 are provided on both sides of the aluminum plate feeding conveying platform 15. The top working surface of the aluminum plate feeding conveying platform 15, the top working surface of the processing station processing platform 162 of the aluminum plate processing station conveying platform 16, and the top working surface of the aluminum plate discharging conveying platform 17 are located on the same horizontal plane. The aluminum plate discharging conveying platform 17 is provided on both sides... The platform is equipped with a discharge conveyor platform track support 171. The aluminum plate feeding conveyor platform 15, the aluminum plate processing station processing platform 162, and the aluminum plate discharge conveyor platform 17 are respectively provided with two grooves.

The two chain U-shaped tracks 14 on the outer side are installed sequentially on the feeding conveyor platform track support 151, the top of both sides of the aluminum plate processing station conveyor platform support plate 161, and the discharge conveyor platform track support 171. The top surface of the chain U-shaped track 14 and the upper chain plate of the annular conveyor chain 3 are both lower than the upper working surface of the aluminum plate processing station processing platform 162.

[0012] Optionally, in some embodiments, at least two aluminum plate processing station conveying platforms 16 are provided. The aluminum plate processing positioning and adjustment mechanism includes a longitudinal positioning lifting cylinder 19 and a transverse positioning centering cylinder 21 disposed on the aluminum plate processing station conveying platform 16.

The longitudinal positioning abutment cylinder 20 is fixedly installed on the push plate of the longitudinal positioning lifting cylinder 19, and its pushing direction is towards the rear side of the aluminum plate processing station conveying platform support plate 161. The transverse positioning centering cylinder 21 is installed on both sides of the aluminum plate processing station processing platform 162, and its pushing direction is towards the middle of the aluminum plate processing station processing platform 162.

[0013] Optionally, in some embodiments, the distance between the two adjacent inner chain U-shaped tracks 14 and the two segments of the annular conveying chain 3 is less than the side length of the aluminum plate, used for conveying the aluminum plate; the distance between the two outer chain U-shaped tracks 14 that are far apart and the two segments of the annular conveying chain 3 is greater than the side length of the aluminum plate.

[0014] Optionally, in some solutions, pallet rollers 18 are provided on the left, center, and right sides of the aluminum plate feeding conveyor platform 15, the aluminum plate processing station conveyor platform 16, and the aluminum plate discharging conveyor platform 17 in the transport direction, respectively. The pallet rollers 18 are made of wear-resistant plastic.

[0015] Optionally, in some embodiments, the U-shaped track 14 of the chain is made of polyethylene.

[0016] The technical solution provided in this application may include the following beneficial effects: This application's conveyor line integrates two major functions: positioning conveying and processing position adjustment. It relies on dual-chain synchronous conveying to achieve continuous flow of aluminum plates, and with the help of the station positioning structure, it completes precise correction. The entire process is automated, which not only ensures stable conveying and high positioning accuracy, but also eliminates the need for manual assistance, effectively improving production efficiency and operational safety. It can adapt to the production needs of multi-station synchronous processing.

[0017] Specifically: (1) The servo motor drive and dual conveyor chain feeding synchronous scheme ensured the consistent conveying speed and positioning accuracy, realized the function of continuously and sequentially conveying aluminum plates from the feeding station to each processing station for positioning and processing and automatic positioning and unloading. Moreover, continuous feeding, conveying and unloading, with aluminum plates being processed at each station at the same time, ensured the continuity of the process and the best production efficiency, improved the level of automation and improved production efficiency. (2) The longitudinal pushing cylinder group eliminates the inertial forward movement of the aluminum plate, and the transverse centering cylinder group eliminates the transverse displacement. Through bidirectional secondary precise positioning, it completely replaces manual push-pull and positioning, eliminates operational safety risks, and improves the inherent safety level. (3) The limit combination consisting of extended positioning pin and limit block achieves smooth pushing. The polyethylene U-shaped track is wear-resistant, self-lubricating, and low-noise. The pallet roller group reduces the friction between feeding and discharging, and the whole machine runs smoothly and reliably.

[0034] Referring to the attached drawings, the continuous and precise positioning and feeding conveyor line for aluminum plates includes an aluminum plate positioning and conveying mechanism and an aluminum plate processing and positioning adjustment mechanism. The aluminum plate positioning and conveying mechanism completes the positioning and conveying of the aluminum plate, and the aluminum plate processing and positioning adjustment mechanism is installed on the aluminum plate positioning and conveying mechanism to complete the position adjustment of the aluminum plate. The aluminum plate positioning and conveying mechanism includes: The active end frame 1 and the driven end frame 2 are arranged parallel to each other on a horizontal plane; Four U-shaped chain tracks 14 are provided and arranged in parallel between the active end frame 1 and the driven end frame 2. The active end frame 1 and the driven end frame 2 are equipped with transmission sprocket sets. Two sets of annular conveyor chains 3 are slidably installed in the four chain U-shaped tracks 14. The two sets of annular conveyor chains 3 are respectively connected to the transmission sprocket sets and run in opposite directions synchronously. An aluminum plate feeding conveyor platform 15, an aluminum plate processing station conveyor platform 16, and an aluminum plate discharging conveyor platform 17 are sequentially arranged between the active end frame 1 and the driven end frame 2. A chain U-shaped track 14 is installed on the aluminum plate feeding conveyor platform 15, the aluminum plate processing station conveyor platform 16, and the aluminum plate discharging conveyor platform 17. The aluminum plate processing positioning and adjustment mechanism is installed on the aluminum plate processing station conveying platform 16 to perform positioning and adjustment of the aluminum plate on the aluminum plate processing station conveying platform 16.

[0035] The machine consists of an aluminum plate positioning and conveying mechanism and an aluminum plate processing and positioning adjustment mechanism. The active end frame 1 and the driven end frame 2 are arranged horizontally and parallel to each other, serving as the support foundation for the entire machine. Four chain U-shaped tracks 14 are installed between the two frames, each carrying two sets of annular conveyor chains 3. The transmission sprocket set drives the two sets of annular conveyor chains 3 to circulate synchronously. Aluminum plates are placed sequentially on the aluminum plate feeding conveyor platform 15 and conveyed forward along the chain U-shaped tracks 14 by the annular conveyor chains 3, arriving one by one at the aluminum plate processing station conveyor platform 16. At this time, the aluminum plate processing and positioning adjustment mechanism installed on the aluminum plate processing station conveyor platform 16 is activated to correct the position of the aluminum plates. After positioning, the processing process begins. After processing, the annular conveyor chains 3 continue to operate, conveying the aluminum plates to the aluminum plate unloading conveyor platform 17 to complete the unloading. The equipment operates in a cycle, realizing the integrated operation of continuous aluminum plate conveying and precise station positioning.

[0036] In some embodiments, both the active end frame 1 and the passive end frame 2 are composed of a bracket and a sprocket mounting platform. The active end frame 1 is arranged on the aluminum plate loading side, and the passive end frame 2 is arranged on the aluminum plate unloading side.

[0037] Both the active end frame 1 and the driven end frame 2 are assembled from brackets and sprocket mounting platforms, resulting in high structural strength and good assembly precision. The active end frame 1 is positioned on the aluminum plate feeding side and is used to install the motor, drive sprocket, and other power components. The driven end frame 2 is positioned on the aluminum plate unfeeding side and is used to install the driven sprocket and auxiliary transmission components. During installation, the two frames are horizontally aligned and placed parallel to each other. The overall structure of the frames supports all transmission and conveying components, ensuring a uniform installation benchmark for subsequent chain, track, and other components, and preventing the circular conveyor chain 3 from deviating and ensuring stable conveying action.

[0038] In some embodiments, the transmission sprocket assembly includes an active conveying sprocket 4 and a driven conveying sprocket 5. The active conveying sprocket 4 is driven by a servo motor 8. A set of annular conveying chains 3 is driven by the active conveying sprocket 4 and three driven conveying sprockets 5 meshing together, forming an active annular conveying chain assembly. Another set of annular conveying chains 3 is connected by four driven conveying sprockets 5 meshing together, forming a driven annular conveying chain assembly. A drive sprocket 10 coaxial with the driven conveying sprocket is installed on one driven conveying sprocket 5 on the active annular conveying chain assembly and one driven conveying sprocket 5 on the driven annular conveying chain assembly. An auxiliary drive sprocket 11 is also rotatably installed in the driven annular conveying chain assembly. A drive chain 9 meshes between the two drive sprockets 10 coaxial with the driven conveying sprocket and the auxiliary drive sprocket 11. The active annular conveying chain assembly drives the driven annular conveying chain assembly to run in the opposite direction, so that the adjacent sides of the two sets of annular conveying chains 3 run in the same direction, ensuring that the two sets of annular conveying chains 3 run synchronously in a cyclic manner.

[0039] The transmission sprocket group is divided into a driving conveyor sprocket 4 and a driven conveyor sprocket 5. A servo motor 8 serves as the power source, driving the driving conveyor sprocket 4 to rotate, which in turn drives a set of annular conveyor chains 3 to rotate, forming a driving annular conveyor chain group. The other set of annular conveyor chains 3 relies on four driven conveyor sprockets 5 to cooperate, forming a driven annular conveyor chain group. The driven conveyor sprockets 5 corresponding to the two sets of annular conveyor chains 3 are respectively fixed with coaxial transmission sprockets 10. The two transmission sprockets 10 and the outer side of the auxiliary transmission sprocket 11 mesh together with the transmission chain 9. During operation, the driving annular conveyor chain group rotates, transmitting power to the driven annular conveyor chain group through the transmission sprockets 10, transmission chain 9, and auxiliary transmission sprocket 11, so that the adjacent sides of the two sets of annular conveyor chains 3 move in the same direction and always maintain synchronous speed, thereby smoothly lifting and pushing the aluminum plate forward, ensuring that the conveying displacement on both sides is consistent and preventing the aluminum plate from shifting.

[0040] In some embodiments, a conveyor chain tensioning device 7 is installed on the active end frame 1, and a conveyor chain tensioning sprocket 6 is rotatably installed on the conveyor chain tensioning device 7. The conveyor chain tensioning device 7 extends and retracts, causing the conveyor chain tensioning sprocket 6 to engage and press the two sets of annular conveyor chains 3 respectively, thus tensioning the annular conveyor chains 3. A drive chain tensioning device 13 is installed on the driven end frame 2, and a drive chain tensioning sprocket 12 is rotatably installed on the drive chain tensioning device 13. The drive chain tensioning sprocket 12 engages with the drive chain 9, thus tensioning the drive chain 9.

[0041] A conveyor chain tension adjustment device 7 is installed on the active end frame 1, with a conveyor chain tension sprocket 6 rotatably mounted at its end. During operation, the extension and retraction of the conveyor chain tension adjustment device 7 can be adjusted to drive the conveyor chain tension sprocket 6 to press the two sets of annular conveyor chains 3 together, compensating for chain gaps in real time and ensuring that the tension of the annular conveyor chains 3 is moderate and that there is no slippage in the transmission. A drive chain tension adjustment device 13 is installed on the driven end frame 1, with a drive chain tension sprocket 12 on it that is in contact with the drive chain 9. The tension of the drive chain 9 is adjusted by the adjustment device to ensure accurate power transmission and synchronous rotation of the two sets of annular conveyor chains 3, further improving the conveying positioning accuracy.

[0042] In some embodiments, aluminum plate pushing and limiting devices are uniformly arranged at certain intervals along the length direction on the upper chain plate of the annular conveyor chain 3. The aluminum plate pushing and limiting device includes an extended positioning pin 31 and a limiting block 32. The extended positioning pin 31 is a chain pin that extends out of the chain and bends in the opposite direction to the forward direction of the chain. The extended positioning pins 31 on the two annular conveyor chains 3 are paired one by one and are in the same position. The limiting block 32 is a wedge-shaped steel block welded to the chain plate. The limiting blocks 32 on the two annular conveyor chains 3 are paired one by one and are in the same position.

[0043] Extended positioning pins 31 and limiting blocks 32 are evenly installed on the upper chain plate of the annular conveyor chain 3. The extended positioning pins 31 and limiting blocks 32 on the two annular conveyor chains 3 are set in pairs synchronously. The extended positioning pins 31 bend in the opposite direction of the chain's forward movement, and the limiting blocks 32 are wedge-shaped steel blocks. The two together form an aluminum plate limiting and pushing structure. During operation, the aluminum plate is stuck between the paired extended positioning pins 31 and limiting blocks 32. When the chain runs, the extended positioning pins 31 push the aluminum plate forward, and the limiting blocks 32 prevent the aluminum plate from shifting due to inertia. The left-right and front-back displacement of the aluminum plate is restricted throughout the entire process, achieving stable conveying.

[0044] In some embodiments, the aluminum plate processing station conveying platform 16 includes an aluminum plate processing station conveying platform support plate 161 and an aluminum plate processing station processing platform 162 for aluminum plate processing, which is disposed on the aluminum plate processing station conveying platform support plate 161. Feeding conveying platform track supports 151 are provided on both sides of the aluminum plate feeding conveying platform 15. The top working surface of the aluminum plate feeding conveying platform 15, the top working surface of the processing station processing platform 162 of the aluminum plate processing station conveying platform 16, and the top working surface of the aluminum plate discharging conveying platform 17 are located on the same horizontal plane. The aluminum plate discharging conveying platform 17 is provided on both sides... The platform includes a discharge conveyor track support 171. The aluminum plate feeding conveyor platform 15, the aluminum plate processing station processing platform 162, and the aluminum plate discharge conveyor platform 17 are each provided with two corresponding grooves. The middle two of the four chain U-shaped tracks 14 are arranged in the grooves. The two outer chain U-shaped tracks 14 are installed sequentially on the feeding conveyor track support 151, the top of both sides of the aluminum plate processing station conveyor platform support plate 161, and the discharge conveyor track support 171. The top surface of the chain U-shaped track 14 and the upper chain plate of the annular conveyor chain 3 are both lower than the upper working surface of the aluminum plate processing station processing platform 162.

[0045] The aluminum plate processing station conveyor platform 16 consists of an aluminum plate processing station conveyor platform support plate 161 and an aluminum plate processing station processing platform 162. The aluminum plate feeding conveyor platform 15 is equipped with a feeding conveyor platform track bracket 151, and the aluminum plate discharging conveyor platform 17 is equipped with a discharging conveyor platform track bracket 171. The top working surfaces of all platforms are on the same horizontal plane to ensure that there is no height difference in the conveying of aluminum plates. Of the four chain U-shaped tracks 14, the inner two are embedded in the reserved grooves of each platform, and the outer two are fixed to the feeding conveyor platform track bracket 151, the aluminum plate processing station conveyor platform support plate 161, and the discharging conveyor platform track bracket 171, respectively. At the same time, the top surface of the chain U-shaped track 14 and the upper chain plate of the annular conveyor chain 3 are lower than the working surface of the platform. The aluminum plate is supported by the platform throughout the process, and the chain only plays a pushing role, avoiding chain deformation under load and ensuring smooth conveying.

[0046] In some embodiments, at least two aluminum plate processing station conveying platforms 16 are provided. The aluminum plate processing positioning and adjustment mechanism includes a longitudinal positioning lifting cylinder 19 and a transverse positioning centering cylinder 21 disposed on the aluminum plate processing station conveying platform 16. The longitudinal positioning lifting cylinder 19 is longitudinally fixed on the front side of the aluminum plate processing station conveying platform support plate 161. The longitudinal positioning abutment cylinder 20 is fixedly installed on the push plate of the longitudinal positioning lifting cylinder 19, and its pushing direction is towards the rear side of the aluminum plate processing station conveying platform support plate 161. The transverse positioning centering cylinder 21 is installed on both sides of the aluminum plate processing station processing platform 162, and its pushing direction is towards the middle of the aluminum plate processing station processing platform 162.

[0047] At least two conveyor platforms 16 are provided at the aluminum plate processing station to meet the needs of continuous multi-process processing. A longitudinal positioning lifting cylinder 19 is fixed to the front side of the support plate 161 of the aluminum plate processing station conveyor platform. A longitudinal positioning abutment cylinder 20 is installed on the push plate of the longitudinal positioning lifting cylinder 19. Lateral positioning centering cylinders 21 are symmetrically installed on both sides of the aluminum plate processing station processing platform 162. After the aluminum plate is conveyed to the processing station and stops, the longitudinal positioning lifting cylinder 19 extends, raising the longitudinal positioning abutment cylinder 20 to the working height. The abutment cylinder then pushes the aluminum plate forward, eliminating longitudinal displacement caused by conveying inertia. Subsequently, the lateral positioning centering cylinders 21 on both sides act sequentially to center and correct the aluminum plate from both sides. After completing bidirectional precise positioning, aluminum plate processing operations can begin.

[0048] In some embodiments, the distance between the two adjacent inner chain U-shaped tracks 14 and the two annular conveyor chains 3 inside them is less than the side length of the aluminum plate, and is used to convey the aluminum plate; the distance between the two outer chain U-shaped tracks 14 that are far apart and the two annular conveyor chains 3 inside them is greater than the side length of the aluminum plate.

[0049] The spacing between the two inner U-shaped tracks 14 and the matching annular conveyor chain 3 is less than the side length of the aluminum plate. During operation, the chains on both sides directly contact the aluminum plate and complete the pushing operation. The spacing between the two outer U-shaped tracks 14 and the matching annular conveyor chain 3 is greater than the side length of the aluminum plate, so the chains will not contact or interfere with the aluminum plate during operation. This layout relies only on the two inner sets of chains to complete the conveying, while the outer chains play a role in auxiliary transmission and balancing the load of the equipment. This simplifies the structure and avoids the outer chains scraping or pushing against the aluminum plate, ensuring stable conveying posture.

[0050] In some embodiments, pallet rollers 18 are provided on the left, center, and right sides of the aluminum plate feeding conveyor platform 15, the aluminum plate processing station conveyor platform 16, and the aluminum plate discharging conveyor platform 17 in the transport direction, respectively. The pallet rollers 18 are made of wear-resistant plastic.

[0051] Wear-resistant plastic pallet rollers 18 are arranged at the left, center, and right positions along the conveying paths of the aluminum plate feeding conveyor platform 15, the aluminum plate processing station conveyor platform 16, and the aluminum plate discharging conveyor platform 17. When the aluminum plate moves on the platform, its bottom contacts the pallet rollers 18, converting sliding friction into rolling friction, which greatly reduces the resistance of the aluminum plate and makes the entire process of feeding, station transfer, and discharging smoother. At the same time, the wear-resistant plastic rollers can be used for a long time, reducing the wear and tear of parts.

[0052] In some embodiments, the U-shaped track 14 of the chain is made of polyethylene.

[0053] The U-shaped track 14 of the chain is made of polyethylene, which is wear-resistant, self-lubricating, low-noise, and impact-resistant. The annular conveyor chain 3 slides back and forth inside the U-shaped track 14 for a long time. The polyethylene track reduces chain wear, eliminates the need for frequent lubrication, and reduces equipment operating noise. It is suitable for the long-term continuous operation of the production line, improving the overall service life and operational stability of the equipment.
