[0028] To further understand the content of this utility model, the following embodiments are described in detail. The embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0029] See attached document Figure 1 , Figure 2 , Figure 3 and Figure 9The fully automated bamboo laminated timber assembly system includes an automatic feeding device 1 for feeding bamboo strips after surface defect detection, a bamboo strip holding device 2 for receiving bamboo strips from the automatic feeding device 1 and moving them forward, a sorting and collecting device 4 located above the bamboo strip holding device 2 for grabbing and stacking the bamboo strips from the holding device 2 to form bamboo strip blanks 3 to be bundled, and an automatic unloading device 5 for dragging, bundling, and transferring the bamboo strip blanks from the sorting and collecting device. This fully automated bamboo laminated timber assembly system offers an ideal assembly method and excellent results, significantly improving the quality of bamboo laminated timber. The system boasts a high degree of automation, featuring automatic feeding, horizontal bamboo strip storage, sorting and collecting, and automatic unloading functions, forming a continuous operation mode and greatly reducing labor costs.

[0030] See attached document Figure 2 , Figure 3 , Figure 5 and Figure 7The automatic feeding device 1 includes a feeding rack 11 for receiving bamboo strips that have been inspected for surface defects by the inspection table 10 and then transferred to it one by one, and a bamboo strip pushing device 12 for pushing the bamboo strips on the feeding rack 11 to the bamboo strip storage device 2. The bamboo strip pushing device 12 is provided with a receiving groove 120 for receiving bamboo strips on the inspection table 10 and a pushing assembly for pushing the bamboo strips in the receiving groove 120 onto the bamboo strip storage device 2. The feeding rack 11 includes a rectangular support located between the bamboo strip storage device 2 and the inspection table 10 and a fixing... A bamboo strip pushing device is installed on the table surface of a rectangular support. This device includes multiple vertical frames 111 arranged sequentially along the length of the table surface. Each frame 111 has a notch horizontally aligned with the groove of the limiting groove 200, and upper and lower guide plates 112 and 113 installed on the notch. The receiving groove 120 is formed between the upper and lower guide plates 112 and 113. The bamboo strip pushing device 12 also includes a pushing assembly that pushes the bamboo strips in the receiving groove 120 onto the bamboo strip holding device 2. The front sections of the upper and lower guide plates 112 and 113 each have outwardly extending, flared sections forming a funnel shape. This funnel design aims to prevent feeding difficulties caused by the bending of the bamboo strips, thus reducing the equipment's failure rate. The detection table 10 is an existing structure of a patent previously filed in the Chinese Patent Database entitled "A Bamboo Strip Defect Detection Table" (Patent No.: ZL202421534837.X, Authorization Publication Date: 2025.04.25). This detection table 10 has a high degree of intelligence in detecting bamboo strip defects, providing comprehensive and precise detection. It can detect information on each bamboo strip for various defects such as dents, missing edges, cracks, and wormholes. The information is processed by an industrial control computer, and a mechanical gripper selectively picks up bamboo strips from the limiting grooves on the rotating belt and places them onto a sorting rack for stacking and assembling into bamboo strip blanks (e.g., 25 bamboo strips per group). Alternatively, the number of bamboo strips in the bamboo strip blanks can be preset to other numbers. The gripper of the mechanical head follows these principles: defective bamboo strips (i.e., strips with differences such as internal carbon, mold, black knots, etc.) are sorted out on the outside, while undefective bamboo strips (i.e., qualified strips) are sorted out on the inside, and bamboo strips with serious defects such as cracks or missing edges are not gripped.

[0031] See attached document Figure 5 and Figure 7The upper guide plate 112 is vertically adjustable to the top of the notch via an L-shaped plate 114. The bottom edge of the L-shaped plate 114 is fixed to the back of the upper guide plate 112, and its side is vertically adjustable to fix the upper guide plate 112 to the top of the notch via fasteners 115. The distance between the upper and lower guide plates 112 and 113 can be adjusted by adjusting the height of the upper guide plate 112. Multiple push bar assemblies are arranged sequentially and at intervals along the length of the rectangular bracket on multiple vertical frames 111.

[0032] See attached document Figure 1 , Figure 4 , Figure 5 and Figure 7 Each pusher assembly includes a strip track 13 mounted on the side wall of the vertical frame 111, a stroke cylinder 14, and a movable base 15 that slides on the strip track 13. The back of the movable base 15 is mounted on the strip track 13 via a slider. The bottom end of the stroke cylinder 14 is connected to the side wall of the vertical frame 111, and its piston rod is connected to the back of the movable base 15. The front of the movable base 15 is provided with a pusher plate 16 that pushes the bamboo strips in the receiving groove 120 laterally into the limiting groove 200. The pusher plate 16 drives the movable base 15 to reciprocate on the strip track 13 through the piston rod of the stroke cylinder 14, thereby completing the bamboo strip pushing operation one by one. The pusher plate 16 is Z-shaped. Its front section is the pusher head, its middle section is the crossbar, and its rear end is the connecting part. This connecting part is movably connected to the front of the movable base 15 via a connector (such as a bolt). The front of the movable base 15 is also equipped with a pulling cylinder 17. The piston rod of the pulling cylinder 17 is connected to the connecting part. The pusher plate 16, through the piston rod of the pulling cylinder 17, pulls the connecting part, causing the pusher head to tilt upwards. This prevents the pusher head from obstructing the rapid entry of the next bamboo strip into the receiving groove. Since the entire equipment operates continuously, especially when bamboo strips are inspected one by one through the inspection table 10, the speed is relatively fast. To ensure uninterrupted feeding of the previous and next bamboo strips, after the previous bamboo strip is pushed, the piston rod of the pulling cylinder 17 pulls the connecting part, causing the pusher head to tilt upwards. This prevents the pusher plate 16 from failing to return to its original position in time, thus avoiding the problem of the next bamboo strip being obstructed from entering quickly.

[0033] See attached document Figure 1 , Figure 2 , Figure 3 and Figure 8The bamboo strip retention device 2 includes a retention rack 21 and a retention rotating belt 20 mounted on the retention rack 21 and driving the bamboo strips forward. The retention rotating belt 20 has multiple limiting grooves 200 arranged sequentially along its length. The groove of one limiting groove 200 at the beginning of the retention rotating belt 20 is horizontally aligned with the receiving groove 120. The feeding rack 11 pushes the bamboo strips from the receiving groove into the multiple limiting grooves 200 one by one through a pushing assembly. The retention rotating belt 20 drives the bamboo strips in each limiting groove 200 to move forward in conjunction with the sorting and collecting process. The device 4 is used in conjunction with the storage rotating belt 20, which includes a drive shaft and a driven shaft mounted on the storage rack 21, and left and right transmission chains 22 and 23 wound between the drive shaft and the driven shaft; it also includes a plurality of carrier chain plates 24 arranged in close proximity between the left and right transmission chains 22 and 23 to form a conveying platform. Each carrier chain plate 24 has a plurality of strip limiting blocks 25 spaced apart along its length. Each strip limiting block 25 has a U-shaped groove, and the U-shaped grooves of the plurality of strip limiting blocks 25 are combined to form the limiting groove 200 for placing a single bamboo strip. Each carrier chain plate 24 has three strip limiting blocks 25 spaced apart along its length, and the three strip limiting blocks 25 are respectively located at the left end, middle and right end of each carrier chain plate 24.
