Description

Technical Field

[0001] This utility model relates to the field of cutting machinery, specifically a preferred edge trimming machine. Background Technology

[0002] A wood edge trimming machine is an automated piece of equipment used in the wood processing industry to trim the edges of wood. It is mainly used to trim the edges of wood into straight lines or smooth surfaces, ensuring edge alignment when splicing boards. Existing wood edge trimming machines do not securely hold the boards firmly enough during trimming or cutting, and their positioning is not accurate enough, leading to incomplete trimming or low utilization of trimmed boards. Therefore, it is necessary to design a new type of wood edge trimming machine. Summary of the Invention

[0003] The purpose of this utility model is to provide a preferred edge-trimming machine, which aims to overcome the above-mentioned problems existing in the prior art.

[0004] To achieve this objective, the present invention provides the following technical solution:

[0005] A preferred edge-trimming saw includes a frame, an electric saw mechanism and a clamping mechanism, an image acquisition mechanism and a pressing mechanism. The frame is provided with a material rack and a saw table, and the rear end of the material rack is connected to the saw table. The clamping mechanism is movably mounted on the frame and is used to clamp the wooden boards on the material rack.

[0006] The frame is equipped with an image acquisition mechanism facing the material rack. The image acquisition mechanism takes pictures of the wooden boards on the material rack, and then the clamping mechanism moves backward to send the clamped wooden boards into the saw table.

[0007] The clamping mechanism includes a pressure rod, which is movably mounted on the frame; by moving the pressure rod downward, the wooden board is clamped between the saw table and the pressure rod;

[0008] Both the saw table and the pressure bar are provided with strip-shaped clearance grooves. These grooves are used to avoid the saw disc of the electric saw mechanism. The electric saw mechanism is mounted on the frame and can be moved up and down. By moving the electric saw mechanism left and right, the saw disc of the electric saw mechanism can cut the wooden board along the strip-shaped clearance grooves.

[0009] Furthermore, the image acquisition mechanism includes three cameras mounted on the frame, one of which is located directly above the material rack and is used to photograph the upper surface of the wooden board; the other two cameras are respectively mounted diagonally above the left and right sides of the material rack and are used to photograph the left and right ends of the wooden board respectively.

[0010] Furthermore, the material rack includes two support rods, which extend forward and backward and are spaced apart on the same horizontal plane.

[0011] Furthermore, it also includes a positioning mechanism, which includes a positioning plate that is adjustable back and forth on the frame and located behind the saw table. The positioning plate is used to support the rear end of the wooden board. By adjusting the position of the positioning plate back and forth, the straight-line distance between the rear end of the wooden board and the saw table is changed.

[0012] Furthermore, it also includes a feeding mechanism for feeding the wooden boards into the material rack.

[0013] Furthermore, the feeding mechanism is a chain conveyor, the rear end of which is connected to the front end of the material rack.

[0014] Compared with the prior art, this utility model has the following advantages:

[0015] Firstly, this utility model, through a material rack, image acquisition mechanism, clamping mechanism, electric saw mechanism, and clamping mechanism, can automatically and quickly complete operations such as moving, fixing, edge trimming, and cutting of wooden boards, ultimately accurately cutting the wooden boards into strips of different sizes. The image acquisition mechanism acquires images of the wooden boards, which can be used for visual recognition and positioning of the boards by the machine. Combined with a pressure bar with a strip-shaped clearance groove, it can accurately and reliably clamp the boards, achieving precise edge trimming and cutting, thereby improving board utilization and product yield.

[0016] Secondly, this utility model also includes a positioning mechanism. After the edge cleaning process is completed, when cutting the wooden board into strips, it can either use the positioning and recognition of the wooden board by the image acquisition mechanism, combined with the clamping mechanism, to quantitatively push the wooden board and cut it into strips of different sizes; or it can adjust the position of the positioning plate of the positioning mechanism, combined with the clamping mechanism, to cut the wooden board into strips of different sizes. Therefore, this utility model has diverse working modes, is flexible in use, and highly automated.

[0017] Thirdly, this utility model also includes a feeding mechanism, which can realize automatic feeding of the machine, improve the working efficiency of the machine and the safety of production. Attached Figure Description

[0025] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Many details are described below to provide a comprehensive understanding of this utility model; however, those skilled in the art can implement this utility model without these details.

[0026] like Figures 1-7 As shown, a preferred edge trimming machine includes a frame 1, which is equipped with a feeding mechanism 2, a baffle 3, a material rack 4, an image acquisition mechanism 5, a clamping mechanism 7, an electric saw mechanism 8, and a clamping mechanism 6. The various mechanisms of the machine are automatically controlled by an industrial control computer (not shown in the figure) to complete assembly line processing such as feeding, clamping, visual recognition and positioning, feeding, clamping, and cutting.

[0027] like Figures 1-7 As shown, the feeding mechanism 2 is located at the front end of the frame 1 and is used to feed the wooden boards into the material rack 4. Preferably, the feeding mechanism 2 is a chain conveyor, the rear end of which is connected to the front end of the material rack 4. Chain conveyors are common conveying devices, and their specific structure will not be described in detail here.

[0028] like Figures 1-7 As shown, a baffle 3 is provided above the rear end of the feeding mechanism 2 on the frame 1. The lower end of the baffle 3 forms a space with the chain conveyor, which can only supply one piece.

[0029] like Figures 1-7 As shown, the frame 1 is equipped with a material rack 4 and a saw table 11. The material rack 4 is used to place wooden boards horizontally, and the rear end of the feeding mechanism 2 is connected to the front end of the material rack 4. The rear end of the material rack 4 is connected to the saw table 11, thereby ensuring that the wooden boards can be moved from the feeding mechanism 2 to the saw table 11.

[0030] Specifically, the material rack 4 includes two support rods 41, which extend forward and backward and are spaced apart on the same horizontal plane to support the left and right ends of the wooden board, ensuring that the wooden board can be placed stably and horizontally. The front end of each support rod 41 is fixedly connected to the rear end of the frame of the feeding mechanism 2, and the rear end is fixedly connected to the front end of the saw table 11.

[0031] like Figures 1-7 As shown, the clamping mechanism 6 is movably mounted on the frame 1. The clamping mechanism 6 includes a left clamping plate 61 and a right clamping plate 62 that can open and close to each other, and a driving device for opening and closing the left clamping plate 61 and the right clamping plate 62.

[0032] like Figures 1-7 As shown, specifically, the driving device includes, but is not limited to, a first rack 631, a second rack 632, a first motor 6310, a second motor 6320, and gears. Specifically, a one-dimensional electric slide module 601 is provided extending forward and backward on the frame 1. A slide module 602 is horizontally mounted between the sliders of the two one-dimensional electric slide modules 601. The left slider 6021 of the slide module 602 is fixed with a left clamping plate 61 and a first rack 631, and the first rack 631 meshes with the gear on the output shaft of the first motor 6310. The right slider 6022 of the slide module 602 is fixed with a right clamping plate 62 and a second rack 632, and the second rack 632 meshes with the gear on the output shaft of the second motor 6320.

[0033] In use, the wooden boards on the material rack 4 are clamped together by the left clamping plate 61 and the right clamping plate 62. The clamping mechanism 6 and the clamped wooden boards move back and forth via the one-dimensional electric slide module 601. When the motor 634 drives the gear 633 to rotate, it drives the first rack 631 and the second rack 632 to move in opposite directions, thereby driving the left clamping plate 61 and the right clamping plate 62 to open and close. Of course, the above-mentioned driving device can also be two cylinders, which drive the left slider 6021 and the right slider 6022 respectively, thereby realizing the opening and closing movement of the left clamping plate 61 and the right clamping plate 62.

[0034] Preferably, the clamping surfaces of the left clamping plate 61 and the right clamping plate 62 are provided with concave and convex textures to prevent slippage when the clamping mechanism 6 clamps the wooden board and moves backward.

[0035] like Figures 1-7 As shown, the frame 1 is equipped with an image acquisition mechanism 5 facing the material rack 4, which is used to photograph the wooden board on the material rack 4 in order to determine the position of the wooden board and provide accurate initial position information for the subsequent clamping mechanism 6 to move the wooden board backward in a quantitative manner.

[0036] Preferably, the image acquisition mechanism 5 includes three cameras 51 mounted on the frame 1. One camera is located directly above the material rack 4 to capture the upper surface of the wooden board; the other two cameras are respectively mounted diagonally above the left and right sides of the material rack 4 to capture the left and right ends of the wooden board. The three cameras can capture more information about the wooden board, such as the core of the board, side cracks, etc.

[0037] In use, the industrial control computer uses images captured by three cameras to visually identify and position the wooden board. Based on the visual identification and positioning, the industrial control computer controls the backward movement distance of the clamping mechanism 6, thereby quantitatively feeding the clamped wooden board into the saw table 11, so as to clean the back end of the wooden board and cut it into strips of different sizes.

[0038] like Figures 1-7As shown, the clamping mechanism 7 includes a pressure rod 71, which is movably mounted on the frame 1. In use, the wooden board is clamped between the saw table 11 and the pressure rod 71 by lowering the pressure rod 71.

[0039] Preferably, the frame 1 is equipped with a dual-axis motor 701. The two output shafts of the dual-axis motor 701 are respectively connected to the two ends of the pressure rod 71 through a screw transmission mechanism 702. The screw transmission mechanism 702 is used to convert the rotational motion of the output shaft of the dual-axis motor 701 into the vertical linear movement of the pressure rod 71.

[0040] like Figures 1-7 As shown, both the saw table 11 and the pressure bar 71 are provided with strip-shaped clearance grooves 800. These grooves 800 are used to avoid the saw disc of the electric saw mechanism 8, which is vertically movable on the frame 1. Specifically, the electric saw mechanism 8 is vertically movable on the frame 1 via a one-dimensional electric sliding table module. In use, the left and right movement of the electric saw mechanism 8 causes the saw disc to cut the wooden board along the strip-shaped clearance grooves 800.

[0041] like Figures 1-7 As shown, this utility model also includes a positioning mechanism 9, which includes a positioning plate 91. The positioning plate 91 is adjustable in the front and back and is located behind the saw table 11. The positioning plate 91 is used to support the rear end of the wooden board. By adjusting the position of the positioning plate 91, the straight distance between the rear end of the wooden board and the saw table can be changed, thereby cutting out wooden strips of different sizes.

[0042] Specifically, the positioning plate 91 is movably mounted on the frame 1 and is equipped with a drive component 92 that moves it back and forth and then fixes it. The drive component 92 includes, but is not limited to, an electric lever that can move the positioning plate back and forth to different positions.

[0043] like Figures 1-7 As shown, the working methods of this utility model are as follows:

[0044] Method 1: Using visual positioning to clean the edges of the wooden boards and cut them into strips, specifically including the following steps:

[0045] (1) Feeding: The wooden boards are placed on the feeding mechanism 2 by manual labor or other auxiliary machinery, and the feeding mechanism 2 moves the wooden boards backward to the material rack 4. Multiple wooden boards can be stacked on the feeding mechanism 2, and the feeding mechanism 2 feeds the wooden boards into the material rack 4 one by one from the bottom up.

[0046] (2) Clamping: The clamping mechanism 6 clamps the wooden board on the material rack 4; since the clamping mechanism 6 clamps the wooden board from the left and right sides, it can correct the deflection of the wooden board in the horizontal direction and play a role in straightening the wooden board.

[0047] (3) Visual positioning: The image acquisition mechanism 5 takes pictures of the wooden boards, and the industrial control computer performs visual recognition and positioning of the wooden boards based on the images;

[0048] (4) Edge cleaning: Based on visual recognition and positioning, the clamping mechanism 6 moves the wooden board backward in a quantitative manner so that the rear end of the wooden core of the wooden board enters between the saw table 11 and the pressure rod 71; the pressure rod 71 moves down and cooperates with the saw table 11 to press the wooden board tightly and fix it; the clamping mechanism 6 releases the wooden board and resets backward; the electric saw mechanism 8 moves to the left or right to cut the wooden board, remove the veneer or unevenness at the rear end of the wooden board, and finally make the rear end of the cut wooden board flat and the core.

[0049] (5) Cutting into strips: According to the current position of the wooden board and the required strip size, the clamping mechanism 6 moves the clamped wooden board backward in a fixed amount so that the part of the wooden board to be cut enters between the saw table 11 and the pressure bar 71; the pressure bar 71 moves down and cooperates with the saw table 11 to press the wooden board tightly and fix it; the clamping mechanism 6 releases the wooden board and resets backward; the electric saw mechanism 8 moves to the left or right to cut the wooden board into strips of the required size.

[0050] (6) Repeat step (5) to cut the wooden board into multiple strips.

[0051] Of course, step (4) is not necessary. For example, when the back end of the wooden board is already flat and has a core, step (4) can be skipped and steps (5) and (6) can be executed directly.

[0052] Method 2: The wooden board is cleaned by visual positioning, and then cut into strips by a positioning mechanism. The difference from Method 1 is the cutting into strips in step (5), as follows:

[0053] (5) Cutting into strips: Adjust the position of the positioning plate 91 of the positioning mechanism 9 according to the required strip size, so that the straight distance between the positioning plate 91 and the saw blade is equal to the required strip size; the clamping mechanism 6 moves the clamped wooden board backward so that the rear end of the wooden board is held against the positioning plate 91; the pressure rod 71 moves down and cooperates with the saw table 11 to press the wooden board tightly and fix it; the clamping mechanism 6 releases the wooden board and resets backward; the electric saw mechanism 8 moves to the left or right to cut the wooden board into strips of the required size.

[0054] The above are merely specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial modifications made to this utility model using this concept shall be considered as an infringement of the protection scope of this utility model.
