Technical Field

[0001] The utility model relates to the technical field of automatic weighing and detection, in particular to an automatic weighing and thickness measuring device. Background Art

[0002] The automatic weighing and thickness measuring device is a kind of measuring equipment integrating automation and high precision. It is widely used in production lines that need to measure the weight and thickness of items at the same time. Through advanced sensor technology and data processing system, it realizes automatic weighing and thickness measurement of items, which can significantly improve the automation level of production lines and product quality.

[0003] At present, there are various forms of integrated thickness and weight detection devices on the market, such as the patent number: 201110323884.0, the patent name: A plate thickness and weight online detection integrated machine, which discloses the following content: a load-bearing frame is provided, and a weighing sensor is provided between the bottom of the load-bearing frame and the base, and the weighing sensor is used to weigh the weight of the plate. Columns are provided on both sides of the base, and two sets of upper and lower beams are installed between the two columns. A set of laser displacement sensors are installed on the two sets of beams, and the thickness of the plate is measured by the laser positioning sensor.

[0004] However, although this device can realize the functions of automatic weighing and thickness measurement, it still has some shortcomings. For example, the laser displacement sensor can only move along the direction of the beam, which means that it cannot measure the thickness of multiple points on the plate. In actual production, different products need to measure the thickness at different positions, which makes the equipment not flexible and convenient when adjusting the thickness measurement position. Furthermore, since the load-bearing frame is set on the weighing sensor, the weighing sensor is easily affected by the height and structure of the two sides of the load-bearing frame itself, causing the weighing sensor to fluctuate and affecting the weighing accuracy.

[0021] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0022] It should be noted that the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0023] like Figure 1 , 2 As shown, an automatic weighing and thickness measuring device is provided with a frame 1, a first linear module 2 is provided on the frame 1, a second linear module 3 is provided on the first linear module 2, a thickness measuring bracket 4 is provided on the second linear module 3, the thickness measuring bracket 4 is U-shaped, a ray transmitter 5 and a ray receiver 6 are relatively provided on the thickness measuring bracket 4, a weight measuring support plate 7 is provided on the frame 1, and a weight sensor 8 is provided on the weight measuring support plate 7.

[0024] Specifically, the plate to be measured is placed on the weighing support plate 7, the device is started, and the control system starts the first linear module 2 and the second linear module 3 according to the preset program or user instructions, driving the thickness measuring bracket 4 to move in the horizontal direction. When it moves to the predetermined position, the ray emitter 5 emits rays (such as lasers, X-rays, etc.) to the plate, and the rays penetrate the plate and are received by the ray receiver 6. The ray receiver 6 calculates the thickness of the plate at the current measuring point according to the change in the intensity of the received rays. By setting the first linear module 2 and the second linear module 3, it can be repeated at multiple preset points or in a continuous area to obtain multi-point thickness information of the plate to be measured. While the plate to be measured is placed on the weighing support plate 7, the weight sensor 8 senses the weight of the plate in real time and converts this information into an electrical signal, which is processed and presented in digital form on the display screen. In the present application, by setting the first linear module 2 and the second linear module 3, the automatic movement and multi-point detection of the thickness measuring bracket 4 are realized, thereby improving the detection efficiency; the moving path and detection points of the thickness measuring bracket 4 can be adjusted as needed to adapt to the detection requirements of plates of different sizes and shapes; automatic weighing is achieved by setting a weight sensor 8, and no load-bearing frame is provided on the weight sensor 8, so that the weight sensor 8 can sense the weight of the plate to be measured more directly and accurately, thereby reducing the source of error and improving the weighing accuracy; the present device integrates the two major functions of thickness measurement and weighing into one device, thereby saving space resources and improving the utilization rate of the equipment.

[0025] like Figure 2 , 3 As shown, height adjustment units 9 are provided at both ends of the weight measuring support plate 7, and the height adjustment unit 9 includes an adjustment support plate 91 installed on the frame 1, an adjustment screw 92 is provided on the adjustment support plate 91, an adjustment handle 93 is provided on the top of the adjustment screw 92, a position display 94 is provided between the adjustment screw 92 and the adjustment handle 93, and the weight measuring support plate 7 is threadedly connected to the adjustment screw 92.

[0026] Specifically, the weighing support plate 7 is threadedly connected to the adjusting screw 92, and the weighing support plate 7 can move along its axial direction under the rotation of the adjusting screw 92. The adjusting support plate 91 is fixed on the frame 1, providing a stable support base for the adjusting screw 92. When the adjusting handle 93 is rotated, the adjusting screw 92 rotates accordingly. Since the weighing support plate 7 is threadedly connected to the adjusting screw 92, the rotating adjusting screw 92 will push or pull the weighing support plate 7 up or down along its axial direction, thereby changing its height. Through the use of threaded connection and position display, the height of the weighing support plate 7 can be accurately controlled to ensure the accuracy during the measurement process. By setting the height adjustment unit 9, when the two ends of the weighing support plate 7 are in the same height and in a horizontal state, the object to be measured can be stably placed on the support plate, the weight is evenly distributed, and the signal received by the weight sensor 8 can more accurately reflect the actual weight of the object, thereby improving the accuracy of the measurement, and the accuracy of the weighing system can be achieved within 3g.

[0027] like Figure 1 As shown, four weight sensors 8 are provided, and a load-bearing pad is provided on the weight sensor 8 .

[0028] Specifically, by setting four sensors distributed in different positions, a stable support structure can be formed to reduce measurement fluctuations caused by movement or vibration of the plate to be measured. By setting a load-bearing pad, the pressure of the object to be measured on the weight sensor can be evenly dispersed. The load-bearing pad acts as a buffer layer between the sensor and the object to be measured, which can prevent the object to be measured from directly impacting or scratching the sensor, thereby extending the service life of the sensor.

[0029] like Figure 1 As shown, a positioning plate 10 is provided on the weight measurement support plate 7 .

[0030] Specifically, by setting the positioning plate 10, the placement position of the plate to be tested is effectively controlled, reducing the measurement error caused by inaccurate position. In particular, the positioning plate 10 is used in conjunction with other automated equipment (such as a robot arm, a conveyor belt, etc.) to achieve rapid and accurate placement of the plate to be tested, which not only improves production efficiency, but also reduces manual intervention and errors.

[0031] like Figure 1 , 2 As shown, the first linear module 2 and the second linear module 3 have the same structure. The first linear module 2 is provided with a driving motor 21. The output end of the driving motor 21 is connected to a conveyor belt 22. The conveyor belt 22 is connected to a slider 23. The slider 23 is slidably mounted on a slide rail 24.

[0032] Specifically, the driving motor 21 rotates to drive the conveyor belt 22 to move, and the slider 23 can slide freely on the slide rail 24, and the slide rail 24 provides a stable guide and support for the slider 23. With the movement of the conveyor belt 22, the slider 23 moves linearly along the slide rail 24, thereby driving the second linear module 3 to move. The second linear module 3 has the same structure as the first linear module 2, and the second linear module 3 drives the thickness measuring bracket 4 to move.

[0033] The present application discloses an automatic weighing and thickness measuring device, which is provided with a frame 1, on which a first linear module 2 and a second linear module 3 are provided, on which a thickness measuring bracket 4 is provided, and on which a weight sensor 8 is provided. By providing the first linear module 2 and the second linear module 3, automatic movement and multi-point detection of the thickness measuring bracket 4 are realized, thereby improving the detection efficiency. The moving path and detection points of the thickness measuring bracket 4 can be adjusted as needed to meet the detection requirements of plates of different sizes and shapes. When the thickness measuring bracket 4 moves to a predetermined position, a ray transmitter 5 emits rays to the plate, and the rays penetrate the plate and are received by a ray receiver 6. The radiation receiver 6 calculates the thickness of the plate at the current measuring point according to the change in the intensity of the received radiation; by setting a weight sensor 8, when the plate to be measured is placed on the weight measuring support plate 7, the weight sensor 8 senses the weight of the plate in real time and converts this information into an electrical signal, which is processed and presented on the display screen in digital form. No load-bearing frame is provided on the weight sensor 8, so that the weight sensor 8 can sense the weight of the plate to be measured more directly and accurately, reduce the source of error, and improve the weighing accuracy; the device integrates the two major functions of thickness measurement and weighing in one device, saving space resources and improving the utilization rate of equipment.
