[0002] Stainless steel plates must undergo fine surface treatment before leaving the factory, and roller coating is one of the key steps.

[0041] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. The components of the embodiments of the present invention generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents the selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present invention.

[0042] It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. At the same time, in the description of this application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0043] like Figure 1 and Figure 2 As shown, a stainless steel plate classification and palletizing system in an embodiment of the present invention includes an output device 100, a collection device 200, a material transfer device 300, an adjustment device 400, an extension track 500, an opening and closing device 600, a palletizing area 700 and a palletizing device 800.

[0044] The output device 100 is used to transport the stainless steel plates from front to back. In fact, the output device 100 can be a horizontal conveyor belt, etc., the front side of which is arranged at the output end of the external roller coating device. After the stainless steel plates are roller coated, the roller coated stainless steel plates are transported from front to back to prepare for the classification and stacking of the stainless steel plates.

[0045] The acquisition device 200 is arranged above the rear of the output device 100 to collect the size and posture parameters of the stainless steel plate. In fact, the acquisition device 200 may include an image collector and a processor with computing capabilities, which can capture the size, displacement, angle and other posture information of the stainless steel plate, and then classify the plate and calculate the posture parameters that need to be adjusted. These operations provide the necessary data support for the posture correction and classification stacking of the stainless steel plate, ensuring the smooth progress of the subsequent processes. By automatically acquiring and processing these key parameters, preparations are made for the posture adjustment and classification stacking of the stainless steel plate.

[0046] The two groups of material moving devices 300 are used to drive the stainless steel plate to move horizontally. In fact, the material moving device 300 can be composed of a translational mechanical structure and a plurality of suction cups installed on the translational mechanical structure. These suction cups can firmly absorb the stainless steel plate and move the stainless steel plate under the drive of the translational mechanical structure, thereby realizing the handling and positioning of the plate, and can transfer the stainless steel plate from one position to another, providing convenience for subsequent palletizing operations.

[0047] The adjustment device 400 is arranged at the rear side of the output device 100 and is connected to the acquisition device 200 for communication and drives the two groups of material moving devices 300 to adjust their posture. In fact, the adjustment device 400 can be a kind of adjustment robot arm, which obtains the posture parameters of the corresponding stainless steel plate that need to be adjusted by communicating with the acquisition device 200. For example, if the stainless steel plate needs to be moved forward by 5mm and rotated 2° counterclockwise, the adjustment device 400 first drives the two groups of material moving devices 300 to move backward by 5mm and rotate 2° clockwise synchronously. When the stainless steel plate to be adjusted is transferred to the output device 100, the adjustment device 400 drives the two groups of material moving devices 300 to move forward by 5mm and rotate 2° counterclockwise, so that the two groups of material moving devices 300 can be restored to their original positions. At the same time, the posture of the stainless steel plate is also accurately adjusted, ensuring the smooth progress of the subsequent material moving process.

[0048] The two extension rails 500 are arranged at the rear side of the adjustment device 400 and are used one by one for the movement of the two groups of material transfer devices 300. In fact, the two extension rails 500 are extended from front to back, so that the two groups of material transfer devices 300 can drive the stainless steel plates to move from front to back and enter the corresponding stacking area 700 for the classification and stacking of the stainless steel plates.

[0049] The opening and closing device 600 is used to drive the two extension rails 500 to approach or move away from each other. In fact, the opening and closing device 600 can be two sets of translation drive mechanisms arranged in reverse, which can drive the two extension rails to move left and right. When the two sets of material transfer devices 300 need to drive the stainless steel plates to move forward and backward on the two extension rails 500, the opening and closing device 600 drives the two extension rails 500 to approach each other; when the stainless steel plates need to be stacked in the corresponding stacking area 700, the opening and closing device 600 drives the two extension rails 500 to move away from each other, providing sufficient space for the stacking of the stainless steel plates, ensuring smooth stacking of the stainless steel plates.

[0050] The plurality of stacking areas 700 are sequentially arranged from front to back along the extending direction of the two extension rails 500. In fact, the number of stacking areas 700 depends on the number of types of stainless steel plates that need to be classified and stacked. Stainless steel plates of the same type will be stacked in the same stacking area 700, which can effectively realize the classification and orderly stacking of stainless steel plates, ensure that stainless steel plates of different sizes or types are stored separately, and realize classified stacking of stainless steel plates.

[0051] The plurality of palletizing devices 800 are arranged one by one in the plurality of palletizing areas 700 and are used to transfer the stainless steel plates on the two groups of material transfer devices 300 to the palletizing areas 700. In fact, the palletizing device 800 may be a palletizing robot arm, which is used to pick up the stainless steel plates transported by the material transfer device 300 and palletize the stainless steel plates in the palletizing area 700 where the palletizing device 800 is located, so as to realize the transfer and palletizing of the stainless steel plates.

[0052] The specific working principle of the stainless steel plate classification and stacking system of the present invention is as follows: the output device 100 outputs stainless steel plates of different categories after roller coating, the acquisition device 200 acquires the size and position parameters of these plates, the adjustment device 400 drives the two groups of material transfer devices 300 to act according to the relevant parameters according to the acquisition data of the acquisition device 200, and after the stainless steel plates are transferred from the output device 100 to the two material transfer devices 300, the adjustment device 400 drives the two groups of material transfer devices 300 to reset to the initial position, thereby completing the posture adjustment of the stainless steel plates; two The material moving device 300 is transferred from the adjustment device 400 to the two extension rails 500 according to the type of stainless steel plates, and drives the stainless steel plates to move backward to the corresponding stacking area 700; the corresponding stacking device 800 in the stacking area 700 picks up the stainless steel plates, and the opening and closing device 600 controls the two extension rails 500 to open until the stainless steel plates are stacked in the stacking area 700. The opening and closing device 600 controls the jumping extension rails 500 to reset, and the two groups of the conveying devices return to the adjustment device 400 to stack the next stainless steel plate.

[0053] The stainless steel plate classification and stacking system of the present invention is combined with an output device 100, a collection device 200, a material transfer device 300, an adjustment device 400, an extension track 500, an opening and closing device 600, a stacking area 700 and a stacking device 800. It can automatically classify different types of stainless steel plates on the output device 100, adjust their positions for stacking, and has a low operator participation rate and low labor intensity.

[0054] Specifically, Figure 4As shown, the adjustment device 400 preferably includes a three-coordinate moving table 410, an angle adjustment motor 420 installed at the output end of the three-coordinate moving table 410, and an adjustment table 430 installed at the output end of the angle adjustment motor 420. In fact, when the material transfer device 300 fixes the stainless steel plate on the adjustment table 430, the three-coordinate moving table 410 can drive the stainless steel plate to move forward, backward, left and right, so as to change the position of the stainless steel plate; at the same time, the angle adjustment motor 420 can drive the stainless steel plate to rotate, so as to change the angle of the stainless steel plate, thereby adjusting the posture parameters of the stainless steel plate. In addition, in order to more effectively receive the stainless steel plate leaving the output device 100, the three-coordinate moving table 410 can change the height of the material transfer device 300, so as to better receive the stainless steel plate leaving the material transfer device 300. It is worth mentioning that the output device 100 can be composed of two conveyor belts arranged at intervals on the left and right. When a stainless steel plate needs to be taken up, the three-coordinate moving platform 410 drives the material moving device 300 to move downward and then forward to the bottom of the stainless steel plate on the output device 100, and then drives the material moving device 300 to move upward so that the material moving device 300 grabs the stainless steel plate, and finally drives the stainless steel plate forward and adjusts its posture, which improves the flexibility of operation and enhances the accuracy of the posture adjustment of the stainless steel plate.

[0055] More specifically, Figure 3 As shown, the material moving device 300 preferably includes a translation trolley 310 and a plurality of first adsorption plates 320 installed on the upper side of the translation trolley 310 for adsorbing the lower side of the stainless steel plate. In fact, the translation trolley 310 can be an automatic guided vehicle (AGV trolley), which can drive the first adsorption plate 320 to move forward and backward to a set position; the first adsorption plate 320 can be an electromagnetic adsorption plate or a vacuum adsorption plate, which can adsorb the lower side of the stainless steel plate and drive the stainless steel plate to move. It should be noted that when the collection device 200 collects and analyzes the type of stainless steel plate, and then sends the type information to the translation trolley 310, the translation trolley 310 that receives the type information can drive the stainless steel plate to move to the corresponding stacking area 700 for stacking, thereby realizing classified stacking of stainless steel plates.

[0056] Further, such as Figure 1As shown, the upper side of the adjustment platform 430 is preferably provided with two guide rails 440 corresponding to the two extension rails 500, and the two extension rails 500 and the guide provisions are used for the movement of the translation trolley 310. In fact, the guide rails 440 and the extension rails 500 are matched with each other, that is, the structure and the distance between the two guide rails 440 correspond to the structure and the distance between the two extension rails 500, so that the two translation trolleys 310 can be smoothly transferred between the two extension rails 500 and the guide rails 440, ensuring the smooth transfer of the translation trolley 310 and the accuracy of the transfer, which can ensure that the stainless steel plate maintains the correct position and posture during the entire handling and transfer process.

[0057] Furthermore, Figure 3 As shown, the extension track 500 and the guide track 440 are preferably provided with two guide grooves 510 disposed in opposite directions, and the translation trolley 310 is provided with two sets of moving wheels 311 correspondingly extending into the guide grooves 510, so that the translation trolley 310 can move smoothly in the guide grooves 510 through the moving wheels 311. In addition, the two sets of moving wheels 311 on the same translation trolley 310 are in the two guide grooves 510 of the same extension track 500 or guide track 440, which play a role in limiting the translation of the translation trolley 310 in the left and right positions, thereby ensuring the stability of the movement of the translation trolley 310.

[0058] In a further embodiment of the present invention, Figure 1 , Figure 2 and Figure 7 As shown, the palletizing area 700 is preferably provided with a detection device 900 for detecting the translation trolley 310, and the detection device 900 is in communication connection with the acquisition device 200, the opening and closing device 600 and the palletizing device 800. In fact, the detection device 900 can be a combination of a distance sensor, a photoelectric switch, a position switch, etc., which can detect the position of the translation trolley 310. When the translation trolley 310 moves to the designated palletizing area 700, the detection device 900 controls the palletizing device 800 to grab the stainless steel plate on the translation trolley 310, and then the opening and closing device 600 drives the two extension rails 500 to move away from each other, leaving a palletizing space for the stainless steel plate palletizing, and avoiding the interference of the two extension rails 500 with the stainless steel plate during palletizing.

[0059] Specifically, Figure 7As shown, the translation trolley 310 is preferably provided with a contact roller 312, and the detection device 900 preferably includes a contact switch 910 for contacting the contact roller 312 and a push drive mechanism 920 for pushing the contact switch 910 back and forth. In fact, the push drive mechanism 920 can be a translation stage or a push rod, which can drive the contact switch 910 to move left and right to change the left and right position of the contact switch 910. During operation, when the acquisition device 200 identifies the category of the stainless steel plate and sends the category information to the push drive mechanism 920 in the corresponding stacking area 700, the push drive mechanism 920 in the corresponding stacking area 700 drives the contact switch 910 to approach the extension rail. Once the contact roller 312 on the translation trolley 310 touches the contact switch 910, the translation trolley 310 stops moving, and the push drive mechanism 920 drives the contact switch 910 to reset. The stacking device 800 and the opening and closing device 600 in the corresponding stacking area 700 perform stacking on the stainless steel plate, ensuring that the stainless steel plate can be accurately placed in the designated stacking area 700 according to its type, thereby improving the automation and efficiency of the entire stacking process. More specifically, as Figure 7 and Figure 8 As shown, the contact surface of the contact switch 910 is preferably tilted inward from front to back. When working, the translation trolley 310 drives the contact roller 312 to move from front to back. Within the range of the contact switch 910, the contact between the contact roller 312 and the contact switch 910 becomes closer and closer, ensuring that the contact roller 312 has a sufficient range to contact the contact switch 910 during the backward movement process, ensuring that the contact switch 910 can stably and reliably respond to the movement of the translation trolley 310.

[0060] Specifically, Figure 5 As shown, the opening and closing device 600 preferably includes two left-right symmetrically arranged follow-up blocks 610 and an opening and closing driving mechanism 620 for driving the two follow-up blocks 610 to be synchronously equidistantly close to or away from each other, and the two extension rails 500 are fixed on the upper sides of the two follow-up blocks 610 in a one-to-one correspondence. In fact, the opening and closing driving mechanism 620 may include two push rods arranged in opposite directions, which can drive the two follow-up blocks 610 to move left and right to realize the opening and closing of the extension rails 500; or it may also include a base, a servo motor installed on the base, and a screw connected to the base and connected to the output end of the servo motor, wherein the screw is provided with a first thread segment and a second thread segment with opposite rotation directions and equal lead, so as to realize the synchronous reverse movement of the two arbitrary blocks to realize the opening and closing of the two extension rails 500, which not only ensures the flexibility of operation, but also ensures the synchronization and accuracy of the opening and closing process of the extension rails 500.

[0061] Specifically, Figure 6As shown, the stacking device 800 preferably includes a lifting drive mechanism 810, a lifting plate 820 installed at the output end of the lifting mechanism, and a plurality of second adsorption plates 830 installed on the lower side of the lifting plate 820 for adsorbing the upper side of the stainless steel plate. In fact, the lifting drive mechanism 810 can be a servo lifting component, which can drive the lifting plate 820 and the plurality of second adsorption plates 830 on the lifting plate 820 to move up and down to change their positions, so as to drive the stacking of the stainless steel plates. During the stacking operation, the material moving device 300 drives the stainless steel plate to move below the second adsorption plate 830 in the corresponding stacking area 700, the lifting mechanism drives the second adsorption plate 830 to move down to contact with the upper side of the stainless steel plate, the second adsorption plate 830 adsorbs the upper side of the stainless steel plate, the material moving device 300 releases the adsorption of the stainless steel plate, and the stainless steel plate is transferred to the stacking device 800, and the stacking of the stainless steel plate is achieved.
