Description

Technical Field

[0001] The utility model relates to the technical field of bamboo material processing, in particular to a bamboo strip shape laser testing platform. Background Art

[0002] In the bamboo products industry, bamboo strips need to be spliced ​​into bamboo boards, and then other processes are carried out to make bamboo products. All bamboo strips used must go through two planes to form a uniform and full rectangular cross-section. In order to achieve this effect, the traditional process generally relies on manual visual inspection to screen and classify the shapes of the bamboo strips after breaking, and then plane the bamboo strips in different situations to carry out the corresponding plane cutting process. However, in actual operation, the manual visual inspection method often has misjudgments, resulting in the failure to remove the green and yellow bamboo in the subsequent plane cutting process; or the bamboo strips are over-plane, wasting materials.

[0003] For this purpose, the applicant applied for a Chinese patent in the early years: a bamboo strip shape detection device, patent number: ZL202120404498.3, authorization publication date: 2021.10.22. It discloses a detection device, the detection device includes a bamboo strip inlet and a bamboo strip outlet, a transmission wheel shaft is arranged between the bamboo strip inlet and the bamboo strip outlet, and a shape detection mechanism is arranged on the upper side between the bamboo strip inlet and the bamboo strip outlet, and the shape detection mechanism includes a thickness detection mechanism and a width detection mechanism. Although the bamboo strip shape detection device overcomes the problem of misjudgment due to manual visual inspection, thereby improving the efficiency of bamboo strip shape screening and classification, it also reduces the waste of bamboo materials. However, there are still some shortcomings when the device is in operation. The structural design of the device is not ideal, especially the detection stability of the thickness and width of the bamboo strips is not enough. Since the bamboo strips themselves have a certain degree of bending, such as the bamboo strips with the green bamboo facing down and the yellow bamboo facing up are easily lifted up or even shaken up and down during the process of being transported from the bamboo strip entrance to the bamboo strip exit, the laser sensor of the width detection mechanism may not be able to illuminate the side of the bamboo strip, resulting in inadequate detection of the width of the bamboo strip, and width detection deviation is prone to occur. In addition, the fixed position of the laser sensor of the thickness detection mechanism cannot be adjusted, and calibration is inconvenient. Utility Model Content

[0004] The utility model provides a bamboo strip shape laser testing platform, which aims to overcome the technical problems that the existing bamboo strip shape detection method (i.e., the detection of bamboo strip width and thickness) is not ideal, and the bamboo strip width detection is not in place, width detection deviation and calibration are inconvenient.

[0005] In order to achieve the purpose, the technical solution provided by the utility model is as follows:

[0006] The bamboo strip-shaped laser test bench comprises a frame, on which a bamboo strip inlet, a bamboo strip outlet and a supporting wheel located between the bamboo strip inlet and the bamboo strip outlet and used for conveying the bamboo strip forward are arranged, a pressing plate is arranged directly above the supporting wheel, and a detection channel for detecting the width of the bamboo strip is formed between the supporting wheel and the pressing plate; the frame is also provided with a first laser sensor component for detecting the thickness of the bamboo strip and a second laser sensor component for detecting the width of the bamboo strip, and the second laser sensor component is located on both sides of the detection channel.

[0007] Furthermore, a fixed frame and a movable frame that can be fine-tuned left and right in the fixed frame are provided on the front side of the frame, and the bamboo strip entrance is formed in the movable frame; the first laser sensor assembly includes upper and lower laser sensors fixed on the movable frame and located above and below the bamboo strip entrance, and an adjustment assembly for synchronously adjusting the upper and lower laser sensors left and right, the adjustment assembly includes a guide shaft horizontally arranged on the fixed frame and a guide slider fixed on the movable frame, and the guide slider can slide left and right on the guide shaft, the frame is also provided with a bolt base and a screw rotatably connected to the bolt base, a lug with a screw hole is fixed on the movable frame, and the end portion of the screw is screwed on the screw hole, and the upper and lower laser sensors are synchronously fine-tuned left and right by rotating the screw to drive the lug to move the movable frame left and right, so as to achieve the purpose of laser detection point centering on the upper and lower surfaces of the bamboo strip.

[0008] Furthermore, the pressing plate includes a horizontal section for pressing the upper surface of the bamboo strips and an inclined section connected to the rear end of the horizontal section and inclined upward, the inclined section is fixed on the pressing plate base, and the front side of the supporting wheel is provided with left and right baffles for blocking the left and right sides of the bamboo strips, and the left and right baffles are trumpet-shaped with a larger front opening and a smaller rear opening from front to back.

[0009] Furthermore, the second laser sensor assembly includes a laser base connected to the frame, and left and right laser sensors fixed on the laser base and respectively performing laser detection on the left and right sides of the bamboo strips on the supporting wheel.

[0010] Compared with the prior art, the technical solution provided by the utility model has the following beneficial effects: the structural design of the bamboo strip shape laser test bench is ideal, and the design of the support wheel and the pressure plate can press the upper surface of the bamboo strip to avoid the problem of the bamboo strip tilting and preventing it from shaking up and down, making it easier for the second laser sensor component to detect the width of the bamboo strip and improving the accuracy of the detection. If the bamboo strip with the green side facing up and the yellow side facing down (i.e. the bamboo strip bent downward) is transported from the bamboo strip entrance to the bamboo strip exit, since the upper surface of the support wheel is an arc-shaped surface, the relative surfaces between the upper surface of the support wheel and the bottom surface of the bamboo strip are more closely fitted, and the bamboo strip is not easy to arch, so that the laser detection point can easily illuminate the side of the bamboo strip to complete the width detection of the bamboo strip, effectivelyReduce Deviation of bamboo strip width detection. The design of a fixed frame and a movable frame that can be fine-tuned left and right in the fixed frame is adopted, so that the upper and lower laser sensors can be fine-tuned left and right by rotating the screw to drive the lug to move the movable frame left and right to achieve the purpose of laser detection side point centering on the upper and lower surfaces of the bamboo strip, making it easy to adjust the fixed position of the laser sensor of the thickness detection mechanism, which is convenient for its calibration.

An anti-penetration strip cover plate 110 is arranged at the bamboo strip inlet 11, and the design of the anti-collision strip cover plate 110 is adopted to prevent the bamboo strip 2 from rushing into the test bench and damaging the device when the worker reverses the bamboo strip. The upper half of the frame 1 is covered with a frame cover 10 for protecting the components thereon from external interference. The frame 1 includes an inner and outer combined support frame 16 and a detection frame 17. The support wheel 13 and the pressure plate 14 are both mounted on the support frame 16; the first and second laser sensor components are both mounted on the detection frame 17. The frame 1 adopts an inner and outer combined design, that is, the support frame 16 and the detection frame 17 are installed separately, so as to prevent the vibration generated when the bamboo strip 2 passes through the support frame 16 from being transmitted to the detection frame 17, thereby affecting the detection of the shape of the bamboo strip (that is, the detection of the width and thickness of the bamboo strip).

[0017] In addition, the bamboo strip shape laser test bench also includes a control system for reading the parameters of the laser sensors of the first and second laser sensor assemblies and outputting the thickness and width information of the bamboo strip 2; the control system includes an AD converter and a PLC controller connected in communication, and the AD converter is connected to the laser sensors of the first and second laser sensor assemblies. The control system is a common existing technology, and its structure and working principle are not described in detail again.

[0018] Refer to the attached Figure 2 and Figure 3The front side of the frame 1 is provided with a fixed frame 31 and a movable frame 32 that can be fine-tuned left and right in the fixed frame 31, and the bamboo strip entrance 11 is formed in the movable frame 32; the first laser sensor assembly includes upper and lower laser sensors 41, 42 fixed on the movable frame 32 and located above and below the bamboo strip entrance 11, and an adjustment assembly for synchronously adjusting the upper and lower laser sensors 41, 42 left and right, and the adjustment assembly includes a guide shaft 33 horizontally arranged on the fixed frame 31 and a guide slider 34 fixed on the movable frame 32, and the guide The slider 34 can slide left and right on the guide shaft 33. The frame 1 is also provided with a bolt base 18 and a screw 19 rotatably connected to the bolt base 18. A lug 35 with a screw hole is fixed to the movable frame 32. The end of the screw 19 is screwed into the screw hole.

[0019] Refer to the attached Figure 1 , Figure 2 and Figure 3 The pressing plate 14 includes a horizontal section 141 for pressing the upper surface of the bamboo strip 2 and an inclined section 142 connected to the rear end of the horizontal section 141 and inclined upward, and the inclined section 142 is fixed on the pressing plate base 143. The front side of the supporting wheel 13 is provided with left and right baffles 131 and 132 for blocking the left and right sides of the bamboo strip 2, and the left and right baffles 131 and 132 are trumpet-shaped from front to back with a large front opening and a small rear opening. The second laser sensor assembly includes a laser base 50 connected to the frame 1 and left and right laser sensors 51 and 52 fixed on the laser base 50 and respectively performing laser detection on the left and right sides of the bamboo strip 2 on the supporting wheel 13. If the bamboo strip with the green bamboo strip facing upward and the yellow bamboo strip facing downward (i.e. the bamboo strip bent downward) is transported from the bamboo strip inlet 11 to the bamboo strip outlet 12, since the upper surface of the supporting wheel 13 is an arc-shaped surface, the upper surface of the supporting wheel 13 and the bottom surface of the bamboo strip 2 are more closely matched, and the bamboo strip 2 is not easy to bend, so that the laser detection point B can easily illuminate the side of the bamboo strip 2, thereby completing the width detection of the bamboo strip, effectively Reduce Deviation of bamboo strip width detection.

[0020] Refer to the attached Figure 1 , Figure 2 , Figure 3 and Figure 4When working, the front end of the laser test bench adopts automatic conveying (such as conveying with a conveyor belt) or manual conveying to allow the bamboo strips 2 to enter from the bamboo strip entrance 11 of the frame 1, pass through the detection channel 15, and then be sent out from the bamboo strip exit 12. When the bamboo strip 2 passes through the bamboo strip entrance 11, the upper and lower laser sensors 41 and 42 arranged above and below respectively obtain the distance between them and the bamboo strip 2 from the upper and lower sides of the bamboo strip 2; when the bamboo strip 2 passes through the detection channel 15, the left and right laser sensors 51 and 52 arranged on the left and right respectively obtain the distance between them and the bamboo strip 2 from the left and right sides of the bamboo strip 2, and the distance information is transmitted to the PLC controller after AD conversion. The PLC controller calculates the width and thickness of the bamboo strip 2 according to the corresponding distance information. The PLC controller can also classify the bamboo strips according to the width and thickness of the bamboo strip 2 in the future. Specifically, the bamboo strips 2 can be marked into various grades, and the bamboo strips 2 can be sorted according to the grades in the subsequent process.
