DETAILED DESCRIPTION

[0021] To more clearly illustrate the technical solutions in the embodiments of the present invention, the above briefly describes the drawings required for describing the embodiments. Obviously, the drawings described only represent some embodiments of the present invention, not all embodiments. Those skilled in the art can also derive other design solutions and drawings based on these drawings without inventive effort.

[0022] The following will clearly and completely describe the concept, specific structure and technical effects of the present invention in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention. In addition, all the connection / connection relationships mentioned in the text do not refer to the direct connection of components, but refer to the fact that a better connection structure can be formed by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the present invention can be combined interchangeably without conflicting with each other.

[0023] During the production and processing of aluminum sheets, they often need to be flipped over to meet the requirements of different processes, such as double-sided polishing, double-sided spraying, and double-sided inspection. Traditional clamping devices have limited flipping angles, requiring frequent disassembly of the aluminum sheet and readjustment of its position and angle to meet the flipping requirements of different processes.

[0024] To this end, the present invention proposes an aluminum plate clamping device, referring to Figures 1 to 4 , which includes: a frame 100, a rotating frame 200, a first driving device 400 and a plurality of clamping assemblies 300; the rotating frame 200 is arranged on the frame 100, and the rotating frame 200 and the frame 100 can rotate relative to each other; all the clamping assemblies 300 are arranged on the rotating frame 200, and the clamping assemblies 300 are used to clamp the aluminum plate; the first driving device 400 is arranged on the frame 100, and the first driving device 400 drives the rotating frame 200 to rotate.

[0025] The rotating frame 200 carries multiple clamping assemblies 300 and the aluminum plate to be turned over, and rotates relative to the frame 100 under the drive of the first driving device 400, thereby driving the aluminum plate to turn over; the fourth driving device 310 controls the two pressing rollers 320 to move away from or close to each other, thereby achieving the clamping and loosening of aluminum plates of different thicknesses; the symmetrical pressing roller 320 structure can ensure that the aluminum plate is evenly stressed during the clamping process, avoiding quality problems such as deformation and scratches on the surface of the aluminum plate due to excessive local stress; the pressing roller 320 structure is very important in the loading and unloading process. It can continuously maintain a clamping state; the present invention drives the pressure rollers 320 to move away from or closer to each other through the fourth drive device 310, which can adapt to aluminum plates of different thicknesses and clamp the aluminum plates to ensure that the aluminum plates will not shift easily during the loading and unloading process, which helps to improve the accuracy and safety of operations such as processing and transportation; the first drive device 400 drives the rotating frame 200 to rotate, so that the clamped aluminum plate can be rotated to a suitable angle as needed, which is convenient for cooperation with other processing equipment or multi-angle installation and other operations, thereby enhancing the applicability and flexibility of the entire device.

[0026] During the processing, the aluminum plate is placed on the clamping assembly 300 on the rotating frame 200, and the fourth driving device 310 of the clamping assembly 300 is used to adjust the spacing between the pressure rollers 320 and clamp the aluminum plate to fix the position of the aluminum plate; under the firm fixation of the aluminum plate clamping assembly 300, single-sided operation links are carried out, such as single-sided grinding, single-sided spraying or single-sided inspection and other processes; when the front and back sides need to be processed alternately, the first driving device 400 is started to drive the rotating frame 200 to rotate relative to the frame 100, thereby driving the aluminum plate clamped by the clamping assembly 300 to rotate together, realizing the flipping action of the aluminum plate, so that the aluminum plate can smoothly enter the double-sided operation link corresponding to the next process, without the need to disassemble the aluminum plate, thereby improving the overall efficiency of aluminum plate processing.

[0027] The traditional driving method may have problems such as unstable transmission and insufficient precision, which affect the accuracy of the turning angle of the aluminum plate and thus affect the processing effect of the aluminum plate. Therefore, in one embodiment, the first driving device 400 includes a first motor 410, a driving wheel 420, a driven wheel 430, a rotating shaft 440 and a synchronous belt 450. The first motor 410 is arranged on the frame 100, the driving wheel 420 is coaxially rotated with the output end of the first motor 410, the rotating shaft 440 is fixedly connected to the rotating frame 200, the driven wheel 430 is coaxially rotated with the rotating shaft 440, and the driving wheel 420 and the driven wheel 430 are connected by the synchronous belt 450. The synchronous belt 450 is not prone to slipping, tooth jumping and other phenomena, making it easier to accurately control the parameters such as the rotation angle and speed of the rotating frame 200, so as to meet the requirements of accurately aligning the double-sided processing position during the aluminum plate turning operation and improve the processing quality of subsequent processes.

[0028] In the production and processing of aluminum plates, the width specifications of aluminum plates are often different. Traditional aluminum plate clamping devices require tedious replacement of parts or complex adjustments to adapt. Therefore, in one embodiment, the aluminum plate clamping device also includes a width adjustment component 500, which includes a first limiter 510, a second limiter 520, a limiter shaft 530, a first sleeve 540 and a second drive device 550. The first limiter 510 is fixedly arranged on the rotating frame 200, the rotating shaft 440 is arranged on the rotating frame 200 and can rotate relative to the rotating frame 200, the second drive device 550 is arranged on the rotating frame 200, and is used to drive the limiter shaft 530 to rotate. The first sleeve 540 is threadedly connected to the limiter shaft 530, and the first sleeve 540 is fixedly connected to the second limiter 520. A working space for clamping the aluminum plate is formed between the first limiter 510 and the second limiter 520. By changing the working space width between the first limit member 510 and the second limit member 520 through the width adjustment component 500, the device can adapt to the clamping requirements of aluminum plates of various width specifications, thereby enhancing the versatility of the entire aluminum plate clamping device; the second drive device 550 drives the second limit member 520 to move through threaded transmission to adjust the clamping width, without the need for manual disassembly or replacement of parts, thereby improving work efficiency and reducing labor intensity; the threaded connection transmission method has high precision and can achieve more accurate width adjustment, ensuring that the aluminum plate is firmly clamped in the appropriate position, providing good basic conditions for subsequent processing procedures.

[0029] Specifically, the second driving device 550 is a hand crank, and the rotating shaft 440 is coaxially rotatable with the output end of the hand crank. In another embodiment, the second driving device 550 is a second motor, and the rotating shaft 440 is coaxially rotatable with the output end of the second motor.

[0030] During the width adjustment process, problems such as the second position-limiting member 520 being unstable in its movement direction or easily offset may occur. Therefore, in one embodiment, the width adjustment assembly 500 further includes a guide shaft 560 and a second sleeve 570, wherein the guide shaft 560 is fixedly disposed on the rotating frame 200, the guide shaft 560 is arranged parallel to the position-limiting shaft 530, the second sleeve 570 is slidably connected to the guide shaft 560, and the second sleeve 570 is fixedly connected to the second position-limiting member 520. The second sleeve 570 slides along the guide shaft 560 to provide guidance for the movement of the second position-limiting member 520, so that the second position-limiting member 520 can always move along the axial direction of the position-limiting shaft 530, thereby ensuring the smoothness and accuracy of the clamping width adjustment.

[0031] When performing continuous operations with the aluminum plate clamping device, relying on manual handling can easily lead to poor connection and inaccurate positioning of the aluminum plate. Therefore, in one embodiment, the aluminum plate clamping device further includes a third driving device 600, a first material moving assembly 700, and a second material moving assembly 800, wherein the first material moving assembly 700 is arranged on the first limiting member 510, the second material moving assembly 800 is arranged on the second limiting member 520, the third driving device 600 is arranged on the frame 100, and the first material moving assembly 700 and the second material moving assembly 800 are both provided with a material moving gap for conveying the aluminum plate, and the third driving device 600 is used to drive the first material moving assembly 700 and the second material moving assembly 800 to rotate so that the aluminum plate is transmitted in the material moving gap. The material transfer gap needles on the material transfer assembly match the specifications of the aluminum plate. The third drive device 600 accurately controls the rotation of the first material transfer assembly 700 and the second material transfer assembly 800, thereby accurately controlling the transmission direction and position of the aluminum plate, avoiding the impact of inaccurate positioning of the aluminum plate on the quality of subsequent processes and ensuring the accuracy of production and processing.

[0032] If the rotation of the first material shifting assembly 700 and the second material shifting assembly 800 is not synchronized, the aluminum plate may be skewed in the material shifting gap, which may cause the aluminum plate to be stuck in the transmission path, damaging the aluminum plate or the material shifting assembly device itself. Therefore, in one embodiment, the third driving device 600 includes a third motor 610, a first sprocket 620, a second sprocket 630, a first chain 640 and a drive shaft 650, wherein the third motor 610 is arranged on the rotating frame 200, the first sprocket 620 is coaxially rotated with the output end of the third motor 610, the drive shaft 650 is arranged on the rotating frame 200 and can rotate relative to the rotating frame 200, the second sprocket 630 is coaxially rotated with the drive shaft 650, the first sprocket 620 and the second sprocket 630 are connected by the first chain 640, and the first material shifting assembly 700 and the second material shifting assembly 800 are both connected by the drive shaft 650. The first sprocket 620 and the second sprocket 630 are driven by the first chain 640, stably transmitting the power of the third motor 610 to the drive shaft 650, and then to the material moving assembly, ensuring that the aluminum plate is transmitted smoothly and uniformly; through the drive shaft 650, the first material moving assembly 700 and the second material moving assembly 800 are simultaneously connected to each other for transmission. With the help of the synchronization of the chain transmission, the two material moving assemblies can achieve synchronous and coordinated rotation under the drive of the drive shaft 650, realizing the smooth transmission of the aluminum plate in the material moving gap, avoiding the problems of skewness, jamming, etc. of the aluminum plate due to inconsistent rotation of the two material moving assemblies, and ensuring the accuracy and efficiency of the aluminum plate transmission.

[0033] Chain slack can cause slippage during transmission, making it impossible for power to be stably transmitted from the drive shaft 650 to the various sprockets and transmission shafts, causing jitter during transmission. Therefore, in one embodiment, the first material moving assembly 700 includes a first gear 710, a second gear 711, a third sprocket 720, a second chain 730, a third chain 740, and a first transmission shaft 712, a second transmission shaft 713, two fourth sprockets 750, two fifth sprockets 760, a plurality of first tensioning wheels 770, and a plurality of second tensioning wheels 780, all of which are arranged on the first limiting member 510. The first transmission shaft 712 and the first limiting member 510 can rotate relative to each other, the first gear 710, the first transmission shaft 712 and one of the fourth sprockets 750 are coaxially arranged, and the second transmission shaft 713 and the first limiting member 510 can rotate relative to each other. Regarding rotation, the second gear 711, the second transmission shaft 713 and one of the fifth sprockets 760 are coaxially arranged for rotation, the first gear 710 is meshed with the second gear 711, the third sprocket 720 is coaxially arranged for rotation with the drive shaft 650, the third sprocket 720 is connected to the two fourth sprockets 750 through the second chain 730, the first tensioning wheel 770 is offset against the second chain 730, the two fifth sprockets 760 are connected through the third chain 740, the second tensioning wheel 780 is offset against the second chain 730, and the material transfer gap is formed between the second chain 730 and the third chain 740. Through the multi-stage transmission of gears and sprockets, and the tensioning wheel to ensure the tension of the chain, the power transmission is stable, the slippage and shaking during the transmission process are reduced, and the aluminum plate can be ensured to be transmitted smoothly; the meshing transmission of the first gear 710 and the second gear 711 ensures the rotation synchronization of the first transmission shaft 712 and the second transmission shaft 713, and then the second chain 730 and the third chain 740 rotate synchronously, which is conducive to the smooth transmission of the aluminum plate; a material transfer gap is formed between the second chain 730 and the third chain 740, and the aluminum plate is placed in the gap. As the second chain 730 and the third chain 740 rotate, the friction between the chain and the aluminum plate is used to drive the aluminum plate to be transmitted in the material transfer gap.

[0034] The chains in the same material moving assembly may be out of sync, resulting in uneven distribution of friction in the material moving gap, and the aluminum plate is prone to twisting, deformation and other problems during transmission. Therefore, in one embodiment, the second material moving assembly 800 includes a third gear 810, a fourth gear 811, a sixth sprocket 820, a fourth chain 830, a fifth chain 840 and a third transmission shaft 812, a fourth transmission shaft 813, two seventh sprockets 850, two eighth sprockets 860, a plurality of third tensioning wheels 870 and a plurality of fourth tensioning wheels 880, all of which are arranged on the second limiter 520. The third transmission shaft 812 and the second limiter 520 are relatively rotatable, the third gear 810, the third transmission shaft 812 and one of the seventh sprockets 850 are coaxially arranged, and the fourth transmission shaft 813 and the second limiter 520 are relatively rotatable. Regarding rotation, the fourth gear 811, the fourth transmission shaft 813 and one of the eighth sprockets 860 are coaxially rotated, the third gear 810 is meshed with the fourth gear 811, the sixth sprocket 820 is coaxially rotated with the drive shaft 650, the sixth sprocket 820 is connected to the two seventh sprockets 850 through the fourth chain 830, the third tensioning wheel 870 is offset against the fourth chain 830, the two eighth sprockets 860 are connected through the fifth chain 840, the fourth tensioning wheel 880 is offset against the fifth chain 840, and the material transfer gap is formed between the fourth chain 830 and the fifth chain 840. A material shifting gap is formed between the fourth chain 830 and the fifth chain 840, and the aluminum plate is placed in the gap. As the fourth chain 830 and the fifth chain 840 rotate, the friction between the chain and the aluminum plate is used to drive the aluminum plate to be transmitted in the material shifting gap; through multi-stage gear and sprocket transmission, and the adjustment of the chain tension by the tensioning wheel, the shaking and slipping during the transmission process are reduced, and the stability of the aluminum plate transmission is improved; the first material shifting component 700 and the second material shifting component 800 work together, so that the chain transmission directions in the two material shifting components are consistent and synchronized, and they act together on the aluminum plate to ensure that the aluminum plate is stable and accurate in the material shifting gap.

[0035] If the aluminum plate is to be clamped, continuous power supply is required to ensure that the relevant drive components are in working condition, which may result in a waste of resources. Therefore, in one embodiment, the fourth drive device 310 includes a fourth motor 311, an externally threaded sleeve 312, a positioning sleeve 313 and a connecting member 314. The externally threaded sleeve 312 is coaxially rotated with the rotor of the fourth motor 311. The pressure roller 320 is connected to the fourth motor 311 via the connecting member 314. The connecting member 314 and the fourth motor 311 can rotate relative to each other. The positioning sleeve 313 is disposed on the rotating frame 200 and is provided with an internal threaded section that engages with the externally threaded sleeve 312. When the motor rotates, the external threaded sleeve 312 will make corresponding axial movement under the action of the thread, thereby driving the connecting piece 314 and the pressure roller 320 to move, and changing the distance between the two pressure rollers 320; in the power-off state, relying on the friction between the threads and the self-locking characteristics of the structure, it can ensure that the pressure roller 320 remains in a closed state, while ensuring the continuous clamping of the aluminum plate during the clamping process, reducing power consumption and lowering the energy consumption cost for long-term use.

[0036] Dynamic deviation of the pressure roller 320 may cause the aluminum plate to be clamped too loosely or too tightly. Therefore, in one embodiment, the positioning sleeve 313 is provided with a limit slot 315, and the connecting member 314 is provided with a limit key 316 that cooperates with the limit slot 315. The guiding and positioning functions of the limit slot 315 and the limit key 316 prevent the aluminum plate from being clamped too loosely or too tightly due to dynamic deviation, helping to improve the accuracy and quality of subsequent aluminum plate processing and installation operations. The connection between the positioning sleeve 313 and the connecting member 314 is also strengthened, reducing the possibility of loosening, misalignment, and other faults between the components during frequent clamping and loosening operations.
