Description

Technical Field

[0001] The present invention relates to the technical field of carrier deformation detection, and in particular to a plate-shaped product carrier deformation detection device and detection method. Background Art

[0002] The statements in this section merely provide background information related to the present disclosure and may not constitute prior art.

[0003] During production and storage, plate-like products generally require a multi-layer structure for storage and placement. For example, the clamps used to support plate-like products such as glass are generally configured as a combination of side supports and middle supports. Due to long-term and high-frequency use, the support structure of the clamps, especially the edge supports, are prone to deformation or skew, or warping, or falling, resulting in a larger or smaller spacing between the upper and lower edge support plates. In addition, since the two sides of the product are supported by the edge supports on both sides, if the edge supports on both sides are not on the same horizontal plane, the product is prone to tilting during storage. If the clamps are deformed in the above situations, it will affect their normal storage performance. If they cannot be detected and repaired in time, it will affect the quality of the stored products and cause an increase in the rate of defective products due to storage conditions.

[0004] In the related technology, the announcement number is CN114964365A, and the name is an invention patent application for an automated three-dimensional warehouse rack anti-tilt detection system and anti-tilt detection method. The anti-tilt detection system is disclosed, which specifically includes a level measuring instrument installed on a cargo platform and a column of a stacker. The level measuring instrument is used to measure the horizontality of the stacker cargo platform and the verticality of the stacker column. A laser rangefinder is installed on the stacker cargo platform, which is used to measure the distance value of the cargo platform from the shelf column at different heights during the continuous lifting process of the stacker, and is also used to measure the height value of the front and rear ends of the same shelf beam. The controller is used to obtain the horizontality, verticality, distance value and height value data generated by the measurement, record and establish a database, and can detect the tilt of the shelf at different angles online to ensure the safe and reliable operation of the storage system.

[0005] The main problems with the existing technologies including the above-mentioned technical solutions when detecting the deformation of plate-like product carriers are: when inspecting large-scale multi-layer equipment, manual visual inspection or tool measurement is generally used, and there are generally problems such as low manual inspection efficiency, easy missed detection, and poor detection accuracy.

[0025] S2: The tilt detection sensor detects the shape of the product to be detected. If the tilt detection sensor recognizes the product to be detected, it is judged as tilted and deformed, and the process goes to S3; otherwise, the process goes to S4;

[0026] S3: The thickness detection sensor detects the thickness of the product to be detected and calculates the tilt angle dT. If the detected tilt angle dT meets the set conditions, it goes to S4; if it does not meet the set conditions, it goes to S7;

[0027] S4: After the lifting mechanism moves to the starting detection position, the detection component is driven to move at a constant speed. During the movement, the internal detection sensor detects the edge support rod and the middle support rod at the corresponding position, and collects the current position of the servo and records it as X. jn and X in ,in i ={1, 2, 3,…,I-2, I-1,I}, j ={1,2,3,…, j -2, j -1, j}, n={1, 2, 3,…, N-2, N-1, N};

[0028] S5: The controller processes the data collected in step S4 and calculates the difference group of the upper and lower adjacent positions detected by the J edge detection sensors in each layer as follows: dX j n =X jn+1 -X jn , the difference group of the upper and lower adjacent positions detected by the middle detection sensor of each layer is: dX in =X in+1 -X in ,in i ={1,2,3,…,I-2,I-1,I}, j ={1,2,3,…, j -2, j -1, j}, n={1, 2, 3,…, N-2, N-1};

If dz-<dX j n <dz+, then it is judged that the corresponding edge support rod has no deformation. If dz-<dX in <dz+, it is judged that the corresponding middle support rod is not deformed, otherwise it is judged as abnormal and an alarm signal is sent;

[0030] S7: The controller processes the data collected in step S4 and calculates the difference group of horizontal adjacent positions in each layer of edge detection sensors as follows: △X jn =X j+1n -X jn , Set the difference range allowed for horizontally adjacent positions to △z-~△z+, where △z- is the minimum value allowed for the difference range for horizontally adjacent positions, and △z+ is the maximum value allowed for the difference range for horizontally adjacent positions. If △z-<△X j n<△z+, it is judged that the corresponding edge column has no deformation, otherwise it is judged as abnormal and an alarm signal is sent;

By setting a lifting mechanism to drive the detection mechanism, the position information of the internal layer structure of the product to be detected can be collected, thereby facilitating the judgment of whether the internal layer structure is deformed. By setting an RFID identification mechanism, it is convenient to identify the identity information of the product to be detected, which is conducive to realizing automated deformation detection operations. By setting a purification component, it is conducive to improving the environmental quality of the entire deformation detection.

[0035] (2) The present invention sets up a deformation detection method for a plate-like product carrier, and uses a lifting mechanism to perform tilt detection on the shape of the product to be detected. At the same time, it also realizes the collection of position information of the internal layer structure of the product to be detected and the determination of the layer spacing, and then detects and determines the deformation of the layer structure of the product to be detected.

[0059] In order to solve the limitations of the prior art, this embodiment provides a technical solution, and the technical solution of the present invention is further described below in conjunction with the drawings and embodiments.

[0060] The present invention is mainly aimed at the technical improvement of the problems of low detection efficiency and poor detection accuracy in the deformation detection of plate-shaped multi-layer products in the related art. The plate-shaped products referred to in this article mainly refer to plate-shaped products such as glass. Such products are generally stored in a multi-layer carrier such as a clip 100. The structure of the clip 100 in this article is shown in the attached Figure 1 and Figure 2, its internal multi-layer structure mainly includes edge struts 101 on both sides and middle struts 102 in the middle, wherein the edge struts 101 are installed on the edge columns 104 in parallel and equidistantly, and the middle struts 102 are installed on the middle columns 103 in parallel and equidistantly, and the edge columns 104 and the middle columns 103 are installed vertically between the top plate and the bottom plate of the clamp 100. The function of the clamp 100 is mainly to provide multi-layer parallel support space, and the edge struts 101 and the middle struts 102 of each layer are in the same plane to provide support for the plate-like product, and the present invention mainly detects whether the overall external shape of the clamp 100 is deformed and whether the internal layer structure is deformed to cause the change of the interlayer distance. The specific structure of the present invention is as follows:

[0061] See attached Figure 3-8A plate-like product carrier deformation detection device includes: a base 200, which supports and positions the product to be detected and is used to install a detection component 300. It can be understood that the base 200 is a frame structure built with steel sections; the base 200 includes a main frame 201 and an alignment mechanism installed on the main frame 201, wherein the main frame 201 includes a base and a frame with a accommodating space located above the base, wherein the accommodating space is mainly used to accommodate the product to be detected and the detection component 300, and the alignment mechanism is used to align and position the product to be detected. The alignment mechanism includes a main alignment mechanism 204, a slave alignment mechanism 203 and two diagonal support mechanisms 205. The main alignment mechanism 204 and the slave alignment mechanism 203 are used to support, align and position the diagonal bottom of the product to be detected, and the two diagonal support mechanisms 205 are respectively used to support the diagonal bottom of the product to be detected. It can be understood here that the main alignment mechanism 204, the slave alignment mechanism 203 and the two diagonal support mechanisms 205 respectively position and support the bottom of the four corners of the product to be detected. Specifically, the main alignment mechanism 204 includes a floating plate 206, a first main limiting power unit 2042 and a second main limiting power unit 2043 installed on the base of the main frame 201, and the power ends of the first main limiting power unit 2042 and the second main limiting power unit 2043 are respectively installed with main limiting units 2041, and the main limiting units 2041 of the two respectively limit the inner angle of the bottom frame of the product to be detected. It can be understood here that the inner angle of the bottom frame of the product to be detected refers to the frame with a bottom angle of 90°. The running routes of the power ends of the first main limiting power unit 2042 and the second main limiting power unit 2043 are perpendicular to each other, from the alignment mechanism 20 The diagonal support mechanism 205 comprises a floating plate 206 mounted on the main frame 201 and a slave limiting power unit 2031. Two slave limiting units 2032 are installed at the power end of the slave limiting power unit 2031. The two slave limiting units 2032 respectively limit and position the inner corners of the bottom frame of the product to be inspected. The first main limiting power unit 2042, the second main limiting power unit 2043 and the slave limiting power unit 2031 all use cylinders. The floating plate 206 mounted on the main frame 201 is used on the diagonal support mechanism 205. The floating plate 206 is used to support the bottom of the product to be inspected and lock it after floating alignment. Here, the floating plate 206 has the functions of support, floating adjustment and locking. Both the main limiting part 2041 and the slave limiting part 2032 use rollers, and the rollers are installed at the power end of the power part through a rotating shaft. It should be emphasized that after the two slave limiting parts 2032 are actuated by the slave limiting power part 2031, they are respectively pressed against the two frame frames at the inner corners of the bottom frame of the product to be detected to limit it. The main alignment mechanism 204 and the slave alignment mechanism 203 both include an in-place sensor for detecting whether the product to be detected is in place by contacting the bottom of the product to be detected. The in-place sensor is installed on the main frame 201, and the in-place sensor uses a pressure sensor 207.

[0062] In addition, see Appendix Figure 4 The base 200 is also equipped with an RFID identification mechanism 202, which is used to identify the identity information of the product to be tested. It can be understood that each product to be tested, i.e., the card holder 100, is provided with a label indicating its identity information, and the RFID identification mechanism 202 is used to identify the product after loading and before testing, thereby facilitating the realization of automated testing operations. Figure 3 A purification component 400 is also installed above the base 200. The purification component 400 includes at least one set of fan filter units. Here, the purification component 400 can be detachably installed on the top of the main frame 201, and can purify the air in the space where the product to be tested is located, thereby protecting the environmental quality around the testing operation space.

[0063] See attached Figure 9-11The detection component 300 is used to perform deformation detection on the appearance and internal layer structure of the product to be detected. Specifically, the detection component 300 includes: a lifting mechanism and a detection mechanism, the lifting mechanism is installed on the base 200 to drive the detection mechanism to lift, the detection mechanism is installed at the power end of the lifting mechanism, the detection mechanism includes a side frame 301 fixedly installed relative to the main frame 201 of the base 200, a horizontal frame 302 slidably installed on the side frame 301 through the lifting mechanism, and a detection part installed on the horizontal frame 302, wherein the side frame 301 is installed on one side of the main frame 201, and the horizontal frame 302 is vertically installed on one side of the side frame 301, and the horizontal frame 302 adopts a U-shaped setting to be inserted into the interior of the product to be detected on the main frame 201, the lifting mechanism includes a lifting power part 304 fixedly installed on the side frame 301, the power end of the lifting power part 304 is fixedly installed relative to the horizontal frame 302, and the horizontal frame 302 and the side frame 301 are slidably installed through a sliding component, and the lifting power part 304 here adopts a servo motor, and the functions of the servo motor in this detection mainly include the following aspects: 1. Control: The servo motor can accurately control its rotation angle and position. During the detection process, the motor moves quickly to the preset start detection position and standby position according to the instructions. 2. Uniform movement: The servo motor moves at a uniform speed to ensure stability and consistency throughout the movement process so that each sensor can accurately record the instantaneous position of the pin. 3. Real-time feedback: The servo motor can monitor its current position in real time. Through the feedback mechanism, the controller can obtain the real-time status of the motor and adjust it as needed. 4. Response control: During the detection process, the servo motor adjusts the movement according to the signal feedback from the sensor to ensure that it reaches the accurate stop position after the detection is completed. 5. High-precision execution: The servo motor has high-precision motion control capabilities, which can ensure the repeatability and consistency of each detection and ensure the accuracy of pin position detection. These functions play a key role in the entire detection process and ensure the efficiency and reliability of the equipment. The sliding assembly includes a slide rail 305 and a slide seat 303. The slide seat 303 is fixedly installed relative to the horizontal frame 302. The slide rail 305 is installed on the side frame 301. The slide seat 303 and the slide rail 305 are slidably installed through a slider. The power end of the lifting power unit 304 is a lead screw nut assembly. The horizontal frame 302 is threadedly installed with the lead screw through the nut seat. The servo motor rotates to drive the nut seat to move up and down along the lead screw, thereby driving the horizontal frame 302 to move up and down. The detection unit is used to perform deformation detection on each layer of the product to be detected.Specifically, the detection part includes M layers of internal detection sensors, and the number of internal detection sensors in each layer is P. Assuming that the number of layers of edge support rods 101 or middle support rods 102 of the product to be detected is N, the number of middle columns 103 is I, and the number of edge columns 104 is J, each layer of internal detection sensors includes I middle detection sensors 306 and J edge detection sensors 309, then P=I+J, 1≤M≤N, when M>1, the relationship between the spacing Q between two adjacent layers of internal detection sensors and the height h of the total number of layers of the product to be detected is: Q=h / M, the middle detection sensor 306 and the edge detection sensor 309 are both photoelectric sensors, which are devices that use the photoelectric effect, reflection, refraction or transmission principle of light to detect objects, monitor changes or measure physical quantities (such as distance, speed, position, etc.). When the light beam emitted by a light source (usually an LED or a laser) encounters an object, the characteristics of the light beam (such as intensity, frequency or wavelength) will change, and the sensor detects this change and outputs a corresponding signal. Photoelectric sensors generally include a light source, a receiver, and a signal processing circuit, and have high sensitivity and response speed. Photoelectric sensors can measure the distance between two adjacent edge struts 101 or middle struts 102. When the servo drives the sensor to move, it detects whether there is an object blocking it by emitting and receiving light beams. When the strut enters the sensor's detection range, the sensor will immediately feedback a signal to ensure that the system can respond in time and record the strut position data in real time. The edge detection sensor 309 is installed on the horizontal frame 302 through the edge support frame 307, and the middle detection sensor 306 is installed on the horizontal frame 302 through the middle support frame 310. At the same time, a displacement power unit 308 is installed between the edge support frame 307 and the horizontal frame 302. Here, the displacement power unit 308 uses a displacement cylinder, and its purpose is to achieve horizontal displacement of the edge detection sensor 309, thereby facilitating the edge support. Rod 101 is used for detection. In the embodiment of the present invention, the detection part includes M=2 layers of internal detection sensors, the number of internal detection sensors in each layer is P=15, the number of layers of edge support rods 101 or middle support rods 102 of the product to be detected is N=22, the number of middle columns 103 is I=3, the number of edge columns 104 is J=12, and each layer of internal detection sensors includes 3 middle detection sensors 306 and 12 edge detection sensors 309, wherein the edge detection sensors 309 are located on both sides, 6 on each side, and the relationship between the spacing Q between two adjacent layers of internal detection sensors and the height h of the total number of layers of the product to be detected is: Q=h / 2. The purpose of the setting here is that the internal detection sensor only needs to move half the total height of the product to be detected to complete the detection, thereby saving detection time and improving detection efficiency.

[0064] The detection component 300 also includes a tilt detection mechanism, which includes a plurality of tilt detection sensors 311 installed on the top of the main frame 201 and thickness detection sensors 312 installed on the top and bottom of the main frame 201. The tilt detection sensors 311 are used to detect the outer contour of the product to be detected from top to bottom. There are 8 of them, which are installed on the four corners of the main frame 201 respectively. Two tilt detection sensors 311 are set on each corner, and the installation position is located directly above the four corners of the product to be detected. The two tilt detection sensors 311 on each corner respectively detect the two sides of the corresponding corner of the product to be detected. The thickness detection sensor 312 is used to detect the thickness of the product to be detected. The thickness detection sensor 312 is installed at the top and bottom of the internal space of the main frame 201 through a bracket. There are 4 groups in total. The thickness detection sensors 312 at the top and bottom are one group. Each group of thickness detection sensors 312 is located on a straight line in the vertical direction, mainly to detect the thickness of the product to be detected. The tilt detection sensor 311 adopts a photoelectric sensor, and the thickness detection sensor 312 adopts a laser displacement sensor.

[0065] The present invention also discloses a method for detecting deformation of a plate-shaped product carrier, the method comprising the following steps:

[0066] S1: After the product to be inspected is loaded into the main frame 201 of the base 200, the RFID identification mechanism 202 identifies the identity information of the product to be inspected and enters it into the controller, and the alignment mechanism supports, aligns and positions the product to be inspected;

[0067] S2: The tilt detection sensor 311 detects the shape of the product to be detected. If the tilt detection sensor 311 recognizes the product to be detected, it is determined to be tilted and deformed, and the process goes to S3. Otherwise, the process goes to S4. It can be understood that the tilt detection sensor 311 is installed on the top of the main frame 201 and detects from top to bottom. If the product is deformed and tilted, the tilt detection sensor 311 can detect and identify the object, which is considered to be deformed. If the product is not deformed and tilted, the object cannot be detected and is considered to be not deformed.

[0068] S3: The thickness detection sensor 312 detects the thickness of the product to be detected and calculates the tilt angle dT. If the detected tilt angle dT meets the set condition, enter S4. If it does not meet the set condition, enter S7. It can be understood here that the set condition is a manually set allowable tilt angle. The calculation method of the tilt angle is: dT = arccos (dL / L), where L is the length of the side of the product to be detected, and dL is the vertical height of the product to be detected detected by the thickness detection sensor. Here, the tilt angle sensor can detect the vertical height of the product to be detected;

[0069] S4: After the lifting mechanism moves to the starting detection position, the detection assembly 300 is driven to move at a constant speed, where the speed range is 20-50 mm / s, preferably 30 mm / s. During the movement, the internal detection sensor detects the edge support rod 101 and the middle support rod 102 at the corresponding position, and collects the current position of the servo and records them as X jn and X in ,in i ={1,2,3,…,I-2,I-1,I}, j ={1,2,3,…, j -2, j -1, j}, n={1, 2, 3,…, N-2, N-1, N};

[0070] S5: The controller processes the data collected in step S4 and calculates the difference group of the upper and lower adjacent positions detected by the J edge detection sensors 309 in each layer as follows: dX jn =X jn+1 -X jn , the difference group of the upper and lower adjacent positions detected by the middle detection sensor 306 of each layer is: dX in =X in+1 -X in ,in i ={1, 2, 3,…,I-2, I-1,I}, j ={1,2,3,…, j -2, j -1, j}, n={1, 2, 3,…, N-2, N-1};

[0071] S6: Set the allowed difference range of the upper and lower adjacent positions to dz-~dz+, where dz- is the minimum value of the allowed difference range of the upper and lower adjacent positions, and dz+ is the maximum value of the allowed difference range of the upper and lower adjacent positions. If dz-<dX jn <dz+, it is judged that the corresponding edge support rod 101 has no deformation. If dz-<dX in <dz+, it is determined that the corresponding middle strut 102 is not deformed, otherwise it is determined to be abnormal and an alarm signal is sent. It can be understood that this step detects whether the spacing between the upper and lower adjacent edge struts 101 on each edge column 104 meets the requirements, and whether the spacing between the upper and lower adjacent middle struts 102 on each middle column meets the requirements, and then determines whether there is deformation;

[0072] S7: The controller processes the data collected in step S4 and calculates the difference group of horizontal adjacent positions in each layer of edge detection sensor 309 as follows: △X jn =X j+1n -Xjn Set the allowable difference range of horizontal adjacent positions to △z-~△z+, where △z- is the minimum value of the allowable difference range of horizontal adjacent positions, and △z+ is the maximum value of the allowable difference range of horizontal adjacent positions. If △z-<△X j n <△z+, it is determined that the corresponding edge column 104 has no deformation, otherwise it is determined to be abnormal and an alarm signal is sent. It can be understood that this step detects whether there is deformation between adjacent edge support rods 101 on the same layer;
