Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Embodiment 1: Please refer to Figure 1 - Figure 3, An automatic loading and unloading device applicable to the manufacturing and processing of doors and windows in the figure, including a frame 1 and a support plate 101.

[0031] By placing a batch of door and window products on the storage unit 3, and the transfer unit 4 can transfer the door and window products in one side of the storage unit 3 to the bracket 102, and use the limiting unit 2 to limit it, then perform cutting, processing and assembly. After the processing is completed, the product is transferred to the storage unit 3 on the other side through the transfer unit 4, so as to complete the loading and unloading work of a single door and window product. Finally, the lifting unit 5 performs a lifting movement to lower the next door and window product, and then the loading and unloading of doors and windows can be carried out one by one, and batch transfer operations of doors and windows can be carried out. There is no need to adjust the position of the processed doors and windows multiple times. When transferring doors and windows, it is more continuous and accurate, greatly improving the working efficiency of the automatic loading and unloading operation of doors and windows.

[0032] Mounting plates 9 fixed at the bottom corners of the frame 1, universal wheels 10 are installed at the bottom of the mounting plates 9, a support assembly 6 is provided on one side of the universal wheels 10 and is installed on the mounting plates 9, and a linkage assembly 7 is installed between the four groups of support assemblies 6;

[0033] The device can be moved through the installed universal wheels 10, which is convenient for the device to walk, and the support assembly 6 can support and limit the device when the universal wheels 10 are not in use, and the linkage assembly 7 can control multiple groups of support assemblies 6 to be linked, making the operation more convenient and faster.

[0034] Further, referring to Figure 4 and Figure 5 , the limiting unit 2 includes a loading plate 201, a first fixing plate 202, a first limiting block 203, a cylinder 204, a sliding block 205 and a pressing wheel 206. The loading plate 201 is fixedly connected to the inner side of the bracket 102, the first fixing plate 202 is fixed to the top of the bracket 102, two first limiting blocks 203 are symmetrically fixed on the top of the first fixing plate 202, the cylinder 204 is installed on the top of the first limiting block 203, the sliding block 205 is slidably connected to the inside of the first limiting block 203 and the telescopic end of the cylinder 204 is fixed to the top of the first limiting block 203, and the pressing wheel 206 is installed at the bottom of the first limiting block 203.

[0035] After the door and window products are transferred to the bracket 102, the sliding block 205 is driven by the air cylinder 204 to slide within the first limiting block 203, thereby driving the pressing wheel 206 to move downward and press against the door and window products to limit the door and window products.

[0036] Furthermore, referring to Figure 6 , the storage unit 3 includes a storage bin 301, a cover plate 302, and a partition plate 303. The storage bin 301 is disposed inside the top of the supporting frame 103. The cover plate 302 is fixed to the top of the storage bin 301. The partition plate 303 is evenly fixed inside the storage bin 301. One side of the storage bin 301 is closed, and the other side is not closed. The top of the partition plate 303 is used to place and store products.

[0037] Initially, each storage bin 301 of one side of the storage unit 3 is filled with door and window products, and each door and window product is separated by the partition plate 303, so that the door and window products can be stored in batches. Moreover, the storage unit 3 on the other side can receive the processed door and window products, thereby achieving the effect of automatic batch loading and unloading.

[0038] Furthermore, please refer to Figure 3 and Figure 7 , the transfer unit 4 includes a vertical plate 401, an electromagnetic guide rail 402, an electromagnetic slider 403, and a transfer carrier plate 404. The vertical plate 401 is fixed to the support plate 101. The electromagnetic guide rail 402 is fixed to the top of the vertical plate 401. The electromagnetic slider 403 is slidably connected to the electromagnetic guide rail 402. The transfer carrier plate 404 is fixed to the electromagnetic slider 403.

[0039] Through the electromagnetic action of the electromagnetic guide rail 402, the electromagnetic slider 403 is driven to perform a linear motion, and then the transfer carrier plate 404 is driven to perform a horizontal motion, so that the door and window products on the transfer carrier plate 404 can be individually transported between the storage units 3 on both sides.

[0040] Furthermore, referring to Figure 8The lifting unit 5 includes a mounting frame 501, a ball screw 502, a ball nut 503, a lifting block 504, a connecting plate 505 and a No. 1 driving member 506. The mounting frame 501 is fixed to the bottom of the support plate 101. The upper and lower sides of the ball screw 502 are rotatably connected to the mounting frame 501 through a bearing seat. The ball nut 503 and the ball screw 502 are threadedly connected. The lifting block 504 is fixedly sleeved on the outer side of the ball nut 503. The connecting plate 505 is fixed to one side of the lifting block 504. The side of the lifting block 504 away from the connecting plate 505 is slidably connected to the mounting frame 501 through a slider and a guide rail. The bottom of the lifting plate 8 is fixedly connected to the connecting plate 505. The No. 1 driving member 506 is installed at the bottom of the mounting frame 501.

[0041] Specifically, the No. 1 driving component 506 will drive the ball screw 502 to rotate, the ball screw 502 will drive the ball nut 503 to move, and then drive the lifting block 504 to move, the lifting block 504 will drive the lifting plate 8 to move through the connecting plate 505, and the lifting plate 8 will drive the supporting frame 103 to move, so that the door and window products can be controlled to dock with the transfer unit 4 one by one.

[0042] For further information, see Figure 8 The No. 1 driving member 506 includes a No. 2 fixed plate 5061, a No. 1 servo motor 5062, a No. 1 pulley 5063 and a No. 2 pulley 5064. The No. 2 fixed plate 5061 is fixed to the bottom of the installation frame 501. The No. 1 servo motor 5062 is fixedly connected to the installation frame 501 through the No. 2 fixed plate 5061. The No. 1 pulley 5063 is fixed to the output end of the No. 1 servo motor 5062. The No. 2 pulley 5064 is fixedly sleeved with one end of the ball screw 502. The No. 1 pulley 5063 and the No. 2 pulley 5064 are connected by a synchronous belt transmission.

[0043] Specifically, the first servo motor 5062 drives the first pulley 5063 to rotate, the first pulley 5063 drives the second pulley 5064 to rotate through the synchronous belt, and the second pulley 5064 drives the ball screw 502 to rotate, thereby accurately controlling the ball nut 503 to move up and down a certain amount.

[0044] For further information, see Figure 8 The four corners of the lifting plate 8 are slidably connected with the limiting columns 507, the top of the limiting columns 507 is fixed with the limiting plate 508, and the bottom of the limiting columns 507 is fixed on the supporting plate 101. This design makes the lifting plate 8 more stable when moving up and down.

[0045] This solution is a process for batch loading and unloading of door and window products;

[0046] First, initially, the storage bin 301 on one side is empty, and the storage bin 301 on the other side is filled with door and window products in batches, and the door and window products at the bottom are just placed on the top of the transfer carrier 404. When loading, the electromagnetic slider 403 and the electromagnetic guide rail 402 cooperate to drive the transfer carrier 404 to move linearly. After moving to the carrier plate 201, the cylinder 204 drives the sliding block 205 to slide in the No. 1 limit block 203, thereby driving the pressing wheel 206 to move down and press the door and window products to limit the door and window products. At this time, the door and window products can be processed. After the processing is completed, the limiting effect is released, and the transfer carrier 404 moves horizontally to transport the processed door and window products to the empty storage bin 301 on one side again, and then the lifting unit is lifted. Element 5 drives the supporting frame 103 to move up a short distance to allow the transfer carrier 404 to break away from the contact with the door and window products. At this time, the transfer carrier 404 returns to the limit unit 2. At this time, the lifting units 5 on both sides move together. The lifting unit 5 on one side drives the supporting frame 103 to move down to allow the next empty storage bin 301 to move to the same horizontal line as the transfer carrier 404. The lifting unit 5 on the other side drives the supporting frame 103 to move down to allow the next door and window product to move to the initial position of the previous door and window product. After that, the transfer carrier 404 moves horizontally and is put in place again with the next door and window product. At this time, the lifting unit 5 can be controlled to move down a short distance to allow the transfer carrier 404 to contact the door and window products. This process can be repeated to complete the batch loading and unloading of door and window products.

[0047] Example 2: Please refer to Figure 9 - Figure 11 This embodiment further explains the first embodiment, and the difference lies in that the use of the universal wheel 10 is optimized.

[0048] Specifically, the support assembly 6 includes a rotating cylinder 601, a threaded column 602, a positioning nut 603 and a supporting foot pad 604. The rotating cylinder 601 is rotatably connected to the bottom of the mounting plate 9 through a bearing, the positioning nut 603 is fixed to the bottom of the rotating cylinder 601, the threaded column 602 is threadedly connected to the positioning nut 603, the supporting foot pad 604 is fixed to the bottom end of the threaded column 602, a limiting groove 605 is provided on the mounting plate 9, a toothed block 606 is fixed to the top end of the threaded column 602, the toothed block 606 is matched with the limiting groove 605, and the linkage assembly 7 is drivingly connected to the rotating cylinder 601;

[0049] Meanwhile, the linkage component 7 includes a second servo motor 701, a third fixing plate 702, a third belt pulley 703 and a fourth belt pulley 704. One side of the third fixing plate 702 is fixed to the outside of the frame 1. The second servo motor 701 is fixedly connected to the frame 1 through the third fixing plate 702. The third belt pulley 703 is fixed to the output end of the second servo motor 701. The fourth belt pulley 704 is fixedly sleeved on the outside of the rotating cylinder 601. The third belt pulley 703 and the four fourth belt pulleys 704 are connected by a synchronous belt.

[0050] Specifically, when the device is fixed, the second servo motor 701 drives the third belt pulley 703 to rotate. The third belt pulley 703 drives the fourth belt pulley 704 to rotate. The fourth belt pulley 704 drives the rotating cylinder 601 to rotate. Since the third belt pulley 703 and the four fourth belt pulleys 704 are connected by a synchronous belt, the four rotating cylinders 601 will rotate together, thereby driving the four threaded columns 602 to move downward, causing the support feet 604 to lift the frame 1, so that the four universal wheels 10 do not contact the ground. Thus, the device can be supported and limited when the universal wheels 10 are not in use. Similarly, when the device needs to be moved, only need to start the second servo motor 701 to reverse, so that the four threaded columns 602 move upward, making the support feet 604 away from the ground, and finally making the universal wheels 10 contact the ground. At this time, the universal wheels 10 can be used to move the position of the device. Such a design can reduce the contact between the universal wheels 10 and the ground and improve their service life.
