Description

TECHNICAL FIELD

[0001] The utility model belongs to the equipment detection technical field relates to a kind of probe device and detection equipment for calibration detection equipment. BACKGROUND

[0002] In the production process of sheet material (for example, paper, non-woven fabric, copper foil, etc.) products, the detection equipment can detect the parameters such as grammage and area density, and feedback control can be realized according to the detection results. The result data obtained in the detection equipment is generally achieved by ray penetration of the sheet material. However, the ray detection method has problems such as irregular ray attenuation and aging of detection sensor performance, and it is often necessary to calibrate the production products at irregular intervals before the detection equipment is running.

[0003] Currently, the conventional calibration method is to install an additional calibration structure outside the ray probe device of the detection equipment, and the calibration structure is provided with calibration objects corresponding to different specifications of production products, so as to calibrate the detection equipment. For example, patent CN115931634A gives a surface density equipment calibration device and a surface density equipment calibration method. The surface density equipment calibration device is used to calibrate the surface density detection equipment, and the surface density equipment calibration device includes a mounting frame, a standard part and an adjusting part. The mounting frame is used to be installed on the surface density equipment. The standard part includes a plurality of standard areas with different densities. The adjusting part connects the standard part and the mounting frame. The adjusting part is configured to adjust the positions of the plurality of standard areas, so that the plurality of standard areas are moved to the detection station of the surface density equipment one by one. By using the standard part instead of the pole piece to calibrate the surface density equipment, the time spent on making the pole piece is saved, and the efficiency of calibrating the surface density equipment is improved.

[0004] However, the additional calibration structure is installed outside the ray emission probe, and each time the detection equipment is calibrated, the calibration structure needs to be installed and disassembled, which requires a lot of manual work. Moreover, when installing and disassembling the calibration structure, considering the safety factor, the production line equipment needs to stop production, but for sheet material products such as paper, non-woven fabric and copper foil, continuous and uninterrupted production of the production line is the norm, which contradicts the need for irregular calibration of the detection equipment. Either calibration is not possible, or the production line is forced to stop during calibration, which can damage the production line equipment and is not conducive to quality control of the production products, and also affects the output of the production line.

[0005] Therefore, how to calibrate the detection equipment to solve the problems of time-consuming installation and disassembly, insufficient convenience and other problems caused by current external calibration is a problem that needs to be solved by those skilled in the art.

DETAILED DESCRIPTION

[0032] In order to better understand the above technical solutions, the above technical solutions will be described in detail below in combination with the drawings and specific embodiments of the specification.

Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.

The singular form "a", "said" and "the" used in the embodiments of the utility model and the appended claims are also intended to include plural forms, unless the context clearly indicates otherwise.

[0034] It should also be noted that the term "include", "contain" or any other variant thereof is intended to cover non-exclusive inclusion, so that the goods or devices including a series of elements not only include those elements, but also include other elements not explicitly listed, or include the elements inherent in such goods or devices. Without more limitation, the element defined by the sentence "including a" does not exclude the presence of other identical elements in the goods or devices including the element.

[0035] Currently, the additional calibration structure is installed outside the ray emitting probe, and needs to be installed and dismounted every time the detection equipment is calibrated, and the production line equipment needs to stop production when the calibration structure is installed and dismounted.

[0036] Either the calibration cannot be performed, or the production line is forced to stop during calibration. That is, the current design of installing the additional calibration structure outside the ray emitting probe is harmful to the production line equipment, is not conducive to the quality control of the produced products, and also affects the yield of the production line.

[0037] Based on the problems existing in the prior art, the calibration structure is placed in the interior of the probe device to solve the time-consuming, inconvenience, irrationality and unscientificity of dismounting the external calibration structure when the detection equipment is calibrated irregularly.

[0038] As shown in Figure 1 The utility model discloses a detection equipment, which comprises a probe device and a probe mounting plate 3 for calibrating the detection equipment, wherein the probe mounting plate 3 is fixed to the detection equipment, and a probe cover 2 is mounted on the probe mounting plate.

[0039] In the detection equipment, the calibration structure is placed in the interior of the probe device. When the detection equipment is calibrated irregularly, the calibration structure does not need to be repeatedly dismounted and installed.

[0040] For the probe device with the internal calibration structure, as shown in Figures 2-4 A probe device for calibrating a detection equipment, which specifically comprises a probe interior structure 1 and a probe cover 2, wherein the probe interior structure 1 is arranged in the probe cover 2.

[0041] The probe interior structure 1 comprises a calibration assembly 11 and an emitting assembly 12, the calibration assembly 11 comprises a calibration disc 116 and a driving part for driving the calibration disc to move, wherein the calibration disc 116 is movably arranged, and the driving part is connected to the calibration disc 116.

[0042] The emitting assembly 12 is arranged opposite to the calibration disc, the calibration disc 116 is provided with a detection hole and at least one calibration hole 1162, a calibration object is mounted in the calibration hole 1162, and the emitting assembly 12 is used for detecting the calibration object.

[0043] The driving part is used for driving the calibration disc to move, and the movement of the calibration disc includes rotation along a circumference or reciprocating movement along a straight line.

[0044] The calibration disc is provided with two types of holes, namely, detection holes and calibration holes. The detection holes are not provided with calibration objects, and the calibration holes are provided with calibration objects. The emission assembly is oppositely arranged with the calibration disc. The relative degree of the emission assembly and the calibration disc is not specifically limited, and the emission assembly can correspond to the positions of the detection holes and the calibration holes in the movable calibration disc in a certain state. After the calibration disc is moved to a position, the emission assembly detects and calibrates the calibration objects in the calibration holes; the detection holes are not provided with calibration objects, and after the calibration disc is moved to another position, the emission assembly can detect the products being produced by penetrating the detection holes.

[0045] Specifically, the driving component includes a motor 111 and a transmission member. The transmission member is connected with a driving shaft of the motor 111, and is used for transmitting power of the motor 111 to the calibration disc 116 to drive the calibration disc 116 to move. The power control of the calibration disc can be realized by the motor 111.

[0046] Taking the rotation of the calibration disc along the circumference as an example, the calibration disc 116 is provided with an external gear 1161 and a rotating shaft 117. The rotating shaft 117 is fixedly installed on the probe cover 2.

[0047] Corresponding to the specific structure of the calibration disc 116, the transmission member is provided as a driving gear 115. The driving gear 115 is tightly connected with the driving shaft of the motor 111. The driving gear 115 and the external gear 1161 of the calibration disc 116 are meshed to form a gear transmission pair. The rotating shaft 117 of the calibration disc 116 and the probe cover 2 form a rotation pair.

[0048] Since the calibration disc 116 is provided with the external gear 1161 and the rotating shaft 117, the driving gear 115 and the external gear 1161 of the calibration disc 116 are meshed to form a gear transmission pair. The driving gear 115 can transmit the power of the motor 111 to the calibration disc 116 to drive the calibration disc 116 to rotate around the rotating shaft 117.

[0049] During the rotation of the calibration disc 116, the calibration holes 1162 and the detection holes provided on the calibration disc 116 also rotate. When the calibration hole 1162 provided with the calibration object rotates to the position corresponding to the emission assembly 12, the emission assembly 12 detects the calibration object installed in the calibration hole 1162 to obtain detection data, so as to realize the calibration of the detection equipment. When the detection hole without the calibration object rotates to the position corresponding to the emission assembly 12, the detection ray emitted by the emission assembly 12 can penetrate the detection hole and the product being produced to detect the product.

[0050] The calibration disc 116 is provided with the calibration holes and the detection holes at the same time, so that the calibration during the production process can be realized at any time. The calibration and detection processes can be switched at any time by the movement of the calibration disc 116, and the calibration structure does not need to be installed and dismounted for many times.

[0051] To improve the position accuracy of the calibration disc during movement, the calibration assembly 11 further comprises a positioning component for determining the position of the calibration hole 1162 in the calibration disc 116 by monitoring the rotation angle of the motor 111.

[0052] In a specific embodiment, the positioning component comprises a sensing component and a monitoring component connected by a signal, the sensing component is used to determine the starting zero point of the calibration disc 116, and the monitoring component is used to receive the signal of the starting zero point of the sensing component and monitor the rotation angle of the motor 111.

[0053] The detection hole and the calibration hole 1162 are circular and uniformly arranged along the circumference of the calibration disc 116. The number of calibration holes 1162 can be one or more, and the calibration hole 1162 and the detection hole can be uniformly arranged along the circumference of the calibration disc 116.

[0054] In the preparation stage of calibration, when the motor 111 drives the calibration disc 116 to rotate through the driving gear 115, the sensing component first determines the starting zero point of the calibration disc 116, and then the signal of the starting zero point of the sensing component is transmitted to the monitoring component. The monitoring component determines the rotation zero point position of the motor 111 based on the signal of the starting zero point, and then determines the angle of rotation of the motor 111 by monitoring the rotation angle of the motor 111. Through the cooperation of the above starting zero point and rotation angle, the position of the detection hole and the calibration hole 1162 during the rotation of the calibration disc 116 is determined.

[0055] The sensing component for determining the starting zero point of the calibration disc 116 can include a photoelectric sensor 114 and a motor photoelectric mounting plate 113, the motor photoelectric mounting plate 113 is installed on the probe cover 2, and the photoelectric sensor 114 and the motor 111 are installed on the motor photoelectric mounting plate 113.

[0056] The monitoring component for receiving the signal of the starting zero point of the sensing component and monitoring the rotation angle of the motor 111 can use an encoder 112, which is installed at the end of the motor 111.

[0057] During the calibration process, as the calibration disc 116 rotates, the encoder 112 installed at the end of the motor 111 calculates from the rotation zero point position, and determines the rotation degree of the calibration disc 116 through the rotation angle of the motor 111, to realize the accurate positioning of the detection hole and the calibration hole 1162.

[0058] For the calibration disc 116 with multiple calibration holes 1162, as the calibration disc 116 rotates, each calibration hole 1162 will be rotated to the corresponding position of the emission assembly 12 one by one.

[0059] After the calibration disc 116 rotates one round, all the calibration objects on the calibration holes 1162 have passed the measurement of the emission assembly 12. After the calibration is completed, the calibration disc is turned to the position where the detection hole corresponds to the emission assembly 12, and the detection radiation emitted by the emission assembly 12 can pass through the detection hole and the product being produced to detect the product.

[0060] The emission assembly 12 can be an X-ray tube or a β-ray tube, and the calibration object arranged in the calibration hole 1162 can be a reference gauge or a product to be detected. Alternatively, the calibration disc 116 is provided with multiple calibration holes 1162, and the calibration objects arranged in some of the calibration holes 1162 are reference gauges, and the calibration objects arranged in the other calibration holes 1162 are products to be detected.

[0061] The reference gauge is a sheet-shaped material with stable performance, such as PET (polyethylene terephthalate), aluminum foil, stainless steel, etc.

[0062] The calibration object is selected as a reference gauge, and the calibration of the product to be detected by the detection equipment is realized through the corresponding relationship between the reference gauge and the product to be detected, which can solve the shortcomings of time-consuming, labor-intensive, material-consuming, cost-consuming, etc. when the detection equipment is calibrated for multiple specifications of products.

[0063] Operating principle of the probe device during calibration of the detection device

[0064] In the calibration preparation stage, the calibration object in the calibration hole can be a reference gauge material with stable performance, such as PET, stainless steel sheet, aluminum foil, etc., or a sample corresponding to the product to be detected, which is cut, weighed, and real data is obtained in advance during the probe assembly process, and then placed in the calibration hole 1162.

[0065] Then, the motor 111 drives the calibration disc 116 to rotate through the driving gear 115, and the photoelectric sensor 114 is used to monitor the starting zero point on the calibration disc 116 in real time. Once the starting zero point on the calibration disc 116 is monitored, the rotational zero point position of the motor 111 can be determined, and a starting zero point signal is transmitted to the encoder 112. The encoder 112 determines the rotation degree of the calibration disc 116 through the subsequent rotation angle of the motor 111.

[0066] In the calibration process, the motor 111 drives the driving gear 115 to rotate, and the driving gear 115 drives the calibration disc 116 to rotate around the rotation axis 117 of the calibration disc 116 through the external gear 1161. In this process, the encoder 112 detects the rotation angle of the motor 111.

[0067] With the rotation of the calibration disc 116, the calibration objects on the calibration holes 1162 rotate circumferentially around the rotation axis 117, and each calibration hole 1162 passes through the radiation of the emission assembly 12 one by one to give the measurement data obtained by the radiation measurement.

[0068] After the calibration disc 116 rotates one round, all the calibration objects on the calibration holes 1162 are measured, and the measurement data is obtained.

[0069] After the calibration is completed, the calibration disc is rotated to the position corresponding to the detection hole of the emission assembly 12, and the detection radiation emitted by the emission assembly 12 can pass through the detection hole and the product being produced, so that the product is detected.

[0070] The probe device for calibrating a detection equipment and the detection equipment have at least the following beneficial effects:

[0071] (1) The probe device provided by the utility model solves the problems of time-consuming and insufficient convenience in installation and disassembly of external calibration structure during irregular calibration of the detection equipment by arranging the calibration assembly in the internal space.

[0072] (2) The calibration disc is provided with the calibration hole and the detection hole at the same time, so that irregular calibration during production can be realized, the calibration and detection processes can be switched at any time through the movement of the calibration disc, and the calibration structure does not need to be installed and disassembled multiple times.

[0073] (3) The calibration assembly is provided with the positioning component, the sensing element in the positioning component is used for determining the starting zero point of the calibration disc, the monitoring element is used for receiving the signal of the starting zero point of the sensing element and monitoring the rotation angle of the motor, and the position of the calibration hole during rotation of the calibration disc is determined through cooperation of the starting zero point and the rotation angle.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications falling within the scope of the utility model.
