[0003] In the prior art, including the aforementioned patents, finished product sorting is a crucial step in the plywood production process. Sorting allows for the separation of plywood of different qualities and specifications to meet diverse usage needs. Currently, plywood finished product sorting equipment on the market has many shortcomings. During plywood production, due to differences in raw materials and fluctuations in production processes, finished plywood may exhibit dimensional deviations and uneven surfaces. Traditional sorting methods rely heavily on manual labor, which is not only inefficient but also makes it difficult to standardize sorting criteria, severely impacting subsequent processing and product quality. Furthermore, the sorting accuracy is low, making it difficult to accurately identify subtle defects and dimensional differences in plywood. The equipment also has a low degree of automation, failing to achieve fully automated sorting throughout the entire process. To address these issues, this utility model proposes a finished product sorting device for plywood production, aiming to improve sorting efficiency and accuracy, achieve automated sorting, and reduce labor costs.

[0016] Please see Figure 1-5 The present invention provides a technical solution as follows: Example 1: A finished product sorting device for plywood production includes a sorting frame 1, an electric sliding base 2 mounted on the top of the sorting frame 1, a universal joint robotic arm 3 mounted on the bottom rotating shaft of the electric sliding base 2, a negative pressure adsorption seat 4 fixedly connected to the bottom of the universal joint robotic arm 3, a driving sliding assembly 5 slidably mounted on the inner wall of the sorting frame 1, an oversized plate conveyor belt 6 mounted on one side of the sorting frame 1, an adjusting limit plate 7 mounted on the top of the oversized plate conveyor belt 6, a sorting conveyor belt 8 mounted on the bottom of the sorting frame 1, a sorting movable table 9 mounted on the top slide rail position of the sorting conveyor belt 8, and a microprocessor assembly 10 mounted on the top of the sorting conveyor belt 8.

[0017] Furthermore, the drive sliding assembly 5 includes a drive sliding frame 501, a size limiting frame 502, and an adjusting cylinder 503. The drive sliding frame 501 is adsorbed and slidably attached to the inner side of the sorting rack 1. The size limiting frame 502 is fixedly connected to the outer wall of the drive sliding frame 501. The adjusting cylinder 503 is installed on the inner side of the size limiting frame 502. The size limiting frame 502 is connected to another size limiting frame 502 through the adjusting cylinder 503. The drive sliding assembly 5 is located above the sorting moving table 9.

[0018] The aforementioned structure allows for adjustment of the distance between the two size-limiting frame frames 502 by regulating the extension and retraction of the cylinder 503, accommodating plywood of different sizes. Furthermore, the drive sliding assembly 5 is positioned above the sorting table 9, facilitating the processing of the plywood on the sorting table 9.

[0019] Furthermore, the microprocessor component 10 internally includes a chassis 1001, a first lead screw slide 1002, a second lead screw slide 1003 mounted on top, a bracket 1004, a drive cylinder 1005, a grinding block 1006, and hot and cold air external pipes 1007. The chassis 1001 is mounted on the front of the sorting rack 1. The first lead screw slide 1002 is installed inside the chassis 1001, and the second lead screw slide 1003 is mounted on top of the first lead screw slide 1002. The bracket 1004 is fixedly connected inside the chassis 1001. A drive cylinder 1005 is installed inside the 1004. A grinding block 1006 is fixedly connected to the output end of the drive cylinder 1005. A hot and cold air external pipe 1007 is installed on the top of the grinding block 1006. The sliding paths of the first lead screw slide 1002 and the second lead screw slide 1003 are perpendicular to each other. An air hole is opened at the bottom of the grinding block 1006, and the grinding block 1006 is located above the second lead screw slide 1003. A hot and cold air integrated machine is connected to the end of the hot and cold air external pipe 1007. The sorting conveyor belt 8 passes through the casing 1001.

[0020] The hot and cold air in the above structure is blown out from the air hole at the bottom of the grinding block 1006 through the hot and cold air external pipe 1007, and the plywood is dried or cleaned by blowing air while it is being ground.

[0021] Furthermore, the bottom of the negative pressure adsorption seat 4 is provided with several adsorption holes, and the negative pressure adsorption seat 4 is connected to an external negative pressure pump through an air guide pipe. An electromagnetic control valve is installed on the air guide pipe. A pressure sensor is installed on the top of the sorting table 9. The output end of the pressure sensor is electrically connected to the input end of the microprocessor component 10, and an infrared positioner is installed at the edge of the sorting table 9.

[0022] The aforementioned structure is electrically connected to the input of the microprocessor component 10 via the output of a pressure sensor. The pressure sensor can detect the weight of the plywood and transmit the detected signal to the microprocessor component 10, so that the microprocessor component 10 can sort the plywood according to its weight. Furthermore, an infrared positioner is installed at the edge of the sorting table 9, which can accurately locate the position of the plywood, ensuring the accuracy of the processing.

[0023] Furthermore, a slider is fixedly connected to the bottom of the adjusting limit plate 7, and a groove adapted to the slider is opened on the top of the oversized plate conveyor belt 6. A locking bolt is threadedly connected to one side of the adjusting limit plate 7, and the end of the locking bolt abuts against the outer wall of the oversized plate conveyor belt 6.

[0024] The aforementioned right adjustment limit plate 7 is used to limit the plywood during the conveying process to prevent it from shifting during the conveying process.

[0025] Working principle: When the equipment is in use, firstly, the plywood to be sorted is transported to the sorting table 9 by the external conveying equipment. After the infrared positioner detects that the plywood is in place, it transmits the signal to the microprocessor component 10. The microprocessor component 10 controls the drive sliding component 5 to move downward. The distance between the size limiting frame 502 is adjusted by the adjusting cylinder 503 to detect the size of the plywood. Secondly, if the plywood is too large, the microprocessor component 10 controls the electric sliding base 2 and the universal joint robotic arm 3 to move, and the excessively large plywood is adsorbed and transported to the excessively large board conveyor belt 6 through the negative pressure adsorption seat 4, and then transported to the designated position by the excessively large board conveyor belt 6. For plywood that meets the size requirements, the sorting table 9 transports it into the housing 1001. The pressure sensor detects the weight of the plywood and transmits it to the microprocessor 10. Using the inertia of the sorting conveyor belt 8, the plywood to be processed is transported to the platform above the second lead screw slide 1003. The microprocessor 10 performs preliminary grading of the plywood according to the weight information and preset standards. Finally, the first lead screw slide 1002 and the second lead screw slide 1003 drive the grinding block 1006 to the position on the plywood surface that needs to be ground, and the drive cylinder 1005 pushes the grinding block 1006 downward to grind the plywood surface. At the same time, the hot and cold air external pipe 1007 delivers hot and cold air as needed. After the grinding is completed, the sorting conveyor belt 8 transports the plywood to the next process to complete the sorting operation.
