Description

Technical Field

[0001] This utility model mainly relates to the field of thickness detection technology, specifically a plate thickness detection device. Background Technology

[0002] After hot wire cutting, the thickness of each foam board needs to be controlled to meet the requirements of subsequent processing. The required thickness detection accuracy is ±0.5mm, and the incoming board thickness range is 10-80mm. Existing technologies for detecting foam board thickness suffer from insufficient accuracy, leading to the failure to promptly detect and eliminate some defective products (foam boards with thicknesses not meeting requirements). Furthermore, existing detection devices may require manual intervention or have slow detection speeds, failing to meet the demands of high-speed production lines and impacting production efficiency and capacity. Therefore, a foam board thickness detection device is proposed. Utility Model Content

[0003] This utility model provides a solution that is significantly different from existing technologies, addressing the problem that existing technologies are too simplistic. It mainly provides a board thickness detection device to solve the technical problems mentioned in the background section, such as insufficient accuracy in detecting foam board thickness and the need for manual intervention in existing detection devices.

[0004] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0005] A sheet metal thickness detection device includes a conveyor line, on both sides of which are symmetrically mounted brackets. An upper fixed rod and a lower fixed rod are fixedly mounted on one side of each bracket. The lower fixed rod is connected to a first ranging sensor via a first mounting member. The upper fixed rod is connected to a second ranging sensor via a positioning plate. A set of the upper fixed rods is connected to a second positioning photoelectric sensor via a second mounting member. A set of brackets has a fixed frame and a coding machine sequentially mounted on one side, and the fixed frame is connected to the first positioning photoelectric sensor via a third mounting member.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0022] Please refer to the appendix carefully. Figure 1-3 A plate thickness detection device, wherein brackets 2 are symmetrically installed on both sides of the conveyor line 1, and an upper fixing rod 201 and a lower fixing rod 202 are fixedly installed on one side of the brackets 2.

[0023] Specifically, one side of the lower fixed rod 202 is connected to the first ranging sensor 4 via the first mounting rod 3. The first mounting rod 3 includes a first horizontal rod 301, which is connected to the lower fixed rod 202 via two sets of first rod fixing blocks 302. A first horizontal block 303 is provided on the outside of the first horizontal rod 301. The first horizontal block 303 can be connected to the first horizontal rod 301 by bolts, so as to facilitate the adjustment of the position of the first horizontal block 303 during installation. The first horizontal block 303 is connected to the vertical rod 304, which can be connected to the first horizontal block 303 by bolts, so as to facilitate the adjustment of the position of the vertical rod 304 during installation. The top of the vertical rod 304 is fixedly connected to the first ranging sensor 4.

[0024] Specifically, the upper fixing rod 201 is connected to the second ranging sensor 501 through the positioning plate 5.

[0025] To further explain, the conveyor line 1 is used to convey single foam boards, and the conveyor line 1 will not obstruct the first ranging sensor 4 and the second ranging sensor 501.

[0026] To further explain, when the foam board passes through the detection area, the second distance sensor 501 emits a measurement signal, such as laser or ultrasonic wave, to the upper surface of the foam board and receives the reflected signal. Based on the round-trip time or phase change of the signal, the sensor can calculate the distance to the upper surface of the foam board. Similarly, the first distance sensor 4 emits a measurement signal to the lower surface of the foam board and receives the reflected signal. Since the area below the foam board is usually a conveyor line 1 or other supporting structure, these structures are designed to avoid obstructing the first distance sensor 4. Therefore, the first distance sensor 4 can accurately measure the distance to the lower surface of the foam board. By simultaneously acquiring the distance values ​​measured by the upper and lower distance sensors, the device can perform a simple subtraction operation to calculate the thickness of the foam board, i.e.: foam board thickness = distance measured by the upper sensor - distance measured by the lower sensor.

[0027] Specifically, a set of upper fixed rods 201 are connected to the second positioning radiating photoelectric device 7 via the second mounting rod 6. The second mounting rod 6 includes a second horizontal rod 601, and the second horizontal rod 601 is connected to the upper fixed rod 201 via two sets of second rod fixing blocks 602. A second horizontal block 603 is provided on the outside of the second horizontal rod 601. The second horizontal block 603 can be connected to the second horizontal rod 601 by bolts, so as to facilitate the adjustment of the position of the second horizontal block 603 during installation. The second horizontal block 603 is connected to the vertical plate 604, and the vertical plate 604 can be connected to the second horizontal block 603 by bolts, so as to facilitate the adjustment of the position of the vertical plate 604 during installation. One side of the vertical plate 604 is fixedly connected to the second positioning radiating photoelectric device 7.

[0028] Specifically, a set of brackets 2 is equipped with a fixed frame 8 and a coding machine 9 on one side in sequence. The fixed frame 8 is connected to the first positioning photoelectric sensor 11 through a third mounting rod 10. The coding machine 9 can use non-contact inkjet technology to accurately print information on a moving foam board.

[0029] To further explain, the third mounting member 10 includes a third transverse rod 1001, one end of which is connected to the fixing frame 8. A third transverse block 1002 is provided on the outer side of the third transverse rod 1001. The third transverse block 1002 can be connected to the third transverse rod 1001 by bolts, thereby facilitating the adjustment of the position of the third transverse block 1002 during installation. The third transverse block 1002 is connected to the vertical fixing plate 1003, which can be connected to the third transverse block 1002 by bolts, thereby facilitating the adjustment of the position of the vertical fixing plate 1003 during installation. One side of the vertical fixing plate 1003 is fixedly connected to the first positioning radiating photoelectric device 11.

[0030] In a further embodiment, the first ranging sensor 4, the second ranging sensor 501, the second positioning photoelectric sensor 7, the inkjet printer 9, and the first positioning photoelectric sensor 11 are all connected to an external control mechanism.

[0031] To further explain, the first positioning photoelectric sensor 11 and the second positioning photoelectric sensor 7 are used to detect whether the foam board has reached the detection station. They send out a positioning signal to trigger the distance measuring sensor to perform measurement. The transmitter emits a light beam, which shines on the surface of the foam board and reflects back. The receiver receives the reflected light beam and converts it into an electrical signal. When the receiver detects a sufficiently strong reflected light, it determines that the foam board has reached the position and outputs a positioning signal. The first positioning photoelectric sensor 11 and the second positioning photoelectric sensor 7 detect the positioning status of the foam board by emitting and receiving light beams. Their stability and accuracy are crucial to ensuring the automation and precision of the foam board thickness detection device. During inspection and maintenance, special attention should be paid to the alignment of the transmitter and receiver, the reflection effect of the reflective surface, and the stability and accuracy of the signal.

[0032] To further clarify, the length of the foam board detected by this device is greater than the distance between the distance sensor and the inkjet printer 9.

[0033] The specific operation process of this utility is as follows: Foam boards are conveyed one by one on the conveyor line 1. After the first positioning photoelectric sensor 11 and / or the second positioning photoelectric sensor 7 detect the material arrival signal, the ranging sensor is triggered to start working.

[0034] The distance measuring sensor measures the vertical distance between the top and bottom of the foam board and transmits the data to the control mechanism. The control mechanism calculates the thickness of the foam board based on the measurement data and compares it with a preset thickness range. If the foam board thickness does not meet the requirements, the control mechanism controls the inkjet printer 9 to mark the foam board. When the recognition signals of the first positioning photoelectric sensor 11 and the second positioning photoelectric sensor 7 disappear, the control mechanism controls the distance measuring sensor to stop working. Using four distance measuring sensors to simultaneously measure the vertical distance between the top and bottom of both sides of the foam board improves the accuracy and efficiency of the measurement. At the same time, it can also measure the tilted board during the conveying process. By setting the first positioning photoelectric sensor 11 and the second positioning photoelectric sensor 7, the position of the board can be detected when it tilts.

[0035] The present invention has been described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
