Detailed implementation manners

[0031] The following will describe in detail the specific embodiments of the present disclosure with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only for the purpose of illustrating and explaining the present disclosure, and are not intended to limit the present disclosure.

[0032] In the present disclosure, unless otherwise stated, the orientation terms such as "inner" and "outer" refer to the inner and outer of the contour of the component or structure itself; "first", "second", etc. are used to distinguish one element from another, without sequence and importance. In addition, the same reference numerals in different reference drawings represent the same elements.

[0033] In a first aspect of the present disclosure, a detection device is provided. Referring to Figures 1 to 12 as shown, the detection device is used to detect whether the to-be-detected end face of the to-be-detected part 5 conforms to the standard end face. The detection device includes a sleeve 1, a clamping mechanism 2, and a measuring mechanism 3. The sleeve 1 has a first end and a second end opposite to each other along its own length direction. The first end has an opening 101 for the to-be-detected part 5 to be inserted. The clamping mechanism 2 is connected to the sleeve 1 and at least partially extends into the sleeve 1 to clamp the to-be-detected part 5 and guide the to-be-detected part 5 to move along the length direction of the sleeve 1. The measuring mechanism 3 includes a mounting plate 340, a plurality of measuring rod assemblies 310, and a plurality of sensors 320. The plurality of measuring rod assemblies 310 are arranged side by side inside the sleeve 1. Each measuring rod assembly 310 is movably arranged inside the sleeve 1 along the length direction of the sleeve 1. The mounting plate 340 is arranged at the second end. The number of sensors 320 is the same as the number of measuring rod assemblies 310 and is correspondingly arranged on the side of the mounting plate 340 facing the measuring rod assemblies 310. One end of the measuring rod assembly 310 faces the opening 101 for abutting against the to-be-detected end face of the to-be-detected part 5, and the other end faces the sensors 320. The sensors 320 are used to detect the pressure of the to-be-detected part 5 on the sensors 320.

[0034] In the above manner, that is, the detection device provided by the present disclosure, when measuring the end face of a workpiece to be detected 5 such as a profile, the workpiece to be detected 5 can be inserted into the inside of the sleeve 1 through the opening 101 at the first end of the sleeve 1. After clamping the workpiece to be detected 5 by the clamping mechanism 2, the workpiece to be detected 5 is pushed along the length direction of the sleeve 1. The workpiece to be detected 5 will move from the first end towards the second end along the length direction of the sleeve 1. The end face to be measured of the workpiece to be detected 5 will abut against a plurality of measuring rod assemblies 310, and push the plurality of measuring rod assemblies 310 to also move from the first end towards the second end. The other end of the measuring rod assembly 310 will abut against the sensor 320 on the mounting plate 340 during the movement. As the workpiece to be detected 5 is continuously pushed in, the sensors 320 at different positions can feedback the magnitude of the force received at different positions of the end face to be measured of the workpiece to be detected 5. According to the multiple force values feedback by the multiple sensors 320, it can be determined whether the end face to be measured of the workpiece to be detected 5 conforms to the standard end face. Thus, the detection efficiency can be significantly improved.

[0035] Next, several detection methods of the detection device of the present application will be exemplarily introduced.

[0036] In the first exemplary embodiment, the staff can insert the workpiece to be detected 5 with a standard end face into a preset position in the detection device before detection. At this time, record the measurement values of each sensor 320, and a standard range can be set based on this measurement value. The standard range can be set considering the influence of manufacturing tolerances on the basis of the measurement value, or the measurement value can be set as the standard value. Thus, during measurement, the workpiece to be detected 5 is pushed to the preset position. At this time, when the force applied by the measuring rod assembly 310 to the sensor 320 exceeds the preset standard value / standard range, it can be determined that there is a convex protrusion at this position of the end face to be measured. Similarly, when the force applied by the measuring rod assembly 310 to the sensor 320 is less than the standard value / standard range, it can be determined that there is a concave groove at this position of the end face to be measured. Therefore, among all the sensors 320, if there is a sensor 320 whose measured pressure value does not conform to the standard value / standard range, it means that the end face to be measured does not conform to the standard end face. Correspondingly, when the pressure values measured by all the sensors 320 meet the standard value / standard range, it means that the end face to be measured conforms to the standard end face. Thus, this detection device can also be used for detecting the flatness of the end face (end face to be measured) of a profile (workpiece to be detected). Among them, inserting the workpiece to be detected 5 into the preset position can be achieved by any suitable method. For example, marks and observation windows can be set on the sleeve 1. When a certain part of the workpiece to be detected 5 moves to the marked position, it means that the workpiece to be detected 5 is inserted into the preset position. Or, a stop portion can be set inside the sleeve 1, etc. When the workpiece to be detected 5 abuts against the stop portion, it means that the workpiece to be detected 5 is inserted into the preset position. The present disclosure does not make specific limitations on this.

[0037] In a second exemplary embodiment, before detection, the staff can set the relationship between all the sensors 320 according to the standard end face, such as the difference requirement. For example, the difference between the force values measured by each sensor 320 cannot exceed a preset value. For example, taking the standard end face as a plane, to measure whether the end face to be measured meets the standard end face, it is necessary to measure whether the flatness of the end face to be measured meets the requirements. Thus, the difference that meets the requirements can be set to, for example, 0, or considering the influence of manufacturing tolerances in the actual processing process, the difference can be set within a preset range. When, among multiple sensors 320, the difference between the measured value of one or more sensors 320 and the measured value of other sensors 320 is positive and exceeds the preset range, it indicates that there are raised structures or the like at the position of the end face to be measured corresponding to the one or more sensors 320. When, among multiple sensors 320, the difference between the measured value of one or more sensors 320 and the measured value of other sensors 320 is negative and exceeds the preset range, it indicates that there are groove structures or the like at the position of the end face to be measured corresponding to the one or more sensors 320. When the difference between the values detected by multiple sensors 320 is within the preset range, it indicates that the end face to be measured meets the flatness requirement, that is, it meets the standard end face.

[0038] In the above two embodiments, for the convenience of intuitively displaying the results, exemplarily, a controller, a display, etc. can be configured for the detection device, so that the measurement values of the sensors 320 are fed back to the display through the controller. The controller can be a PLC controller or a single-chip microcomputer, etc. It receives data from the sensors 320 and displays them on the display, which is well-known prior art in the field, and the present disclosure will not elaborate on this here.

[0039] In a third exemplary embodiment, the detection device can be used in cooperation with a data processing mechanism such as a computer, a tablet computer, a mobile terminal, etc., such as the detection device mentioned below.

[0040] Among them, when the measuring rod 311 touches the surface of the sensor 320, the sensor 320 will transmit the pressure signal to the circuit board 342 through the support plate 343, and then transmit the magnitude of the pressure value to the external data processing mechanism 4 in the form of a signal, such as a computer, a tablet computer, a mobile terminal or a server, etc. Among them, the method by which the sensor 320 transmits the magnitude of the pressure value to the data processing mechanism 4 such as a computer by sending a signal has been widely used in the prior art and can be sent by wired or wireless means. The present disclosure will not elaborate on this.

[0041] In addition, the data processing mechanism 4 can also automatically generate coordinate points of the end face to be measured in the 3D software according to the magnitude of the signal value, so as to facilitate personnel to determine the specific shape of the end face to be measured. For example, the data processing mechanism 4 can generate coordinate points from the force values fed back by the sensors 320 at multiple different positions, fit the multiple coordinate points, and restore the end face shape of the workpiece 5 to be detected through the 3D software, so as to more intuitively observe the model of the end face to be measured of the workpiece 5 to be detected on the data processing mechanism 4. And a model of the standard end face can be pre-set in the data processing mechanism 4, and the data processing mechanism 4 can directly compare to determine whether the end face to be measured meets the standard end face.

[0042] Of course, the data processing mechanism 4 can also display the pressure values measured by each sensor on its display screen in the form of, for example, a data list, and judge whether the end face to be measured meets the standard end face by manually viewing the pressure values.

[0043] The present disclosure is not limited to the above measurement methods, as long as the values measured by each sensor 320 can reflect whether the end face to be measured meets the standard end face.

[0044] Thus, when the workpiece 5 to be detected is a profile of a frame for fixing the edge of a photovoltaic panel, the end face to be measured of the long strip profile can be inserted into the sleeve 1, and the flatness of the end face to be measured can be measured with reference to the above method. After the flatness of the end face to be measured of the profile is measured and inspected to meet the production standard, the subsequent welding and assembly process can be carried out.

[0045] In some embodiments, with reference to Figures 1 to 12As shown in the figure, the detection device further includes a mounting bracket 330 disposed inside the sleeve 1. The mounting bracket 330 includes a plurality of first limiting holes 331 arranged in one-to-one correspondence with the measuring rod assemblies 310. The measuring rod assemblies 310 include measuring rods 311 and first elastic members 312. The measuring rods 311 are inserted through the corresponding first limiting holes 331. Both ends of the measuring rods 311 are respectively provided with a first abutting portion 311a and a second abutting portion 311b for abutting against the workpiece to be detected 5 and the sensor 320. The first abutting portion 311a is located on the outer side of the mounting bracket 330 facing the opening 101, and the first abutting portion 311a is used for abutting against the end face to be detected. The second abutting portion 311b is used for abutting against the sensor 320. The first elastic member 312 is sleeved on the measuring rod 311 and is located between the first abutting portion 311a and the mounting bracket 330 to provide an elastic force for the measuring rod 311 to move towards the opening 101. In this way, the mounting bracket 330 can limit and support the plurality of measuring rod assemblies 310 through the plurality of first limiting holes 331, enabling the plurality of measuring rod assemblies 310 to be more stably disposed inside the sleeve 1, so as to ensure that when the measuring rod assemblies 310 contact the end face to be detected, they only reciprocate along their own length directions, thereby improving the accuracy of the force transmitted to the sensor 320. When the measuring rod 311 contacts the end face to be detected and the sensor 320, the first abutting portion 311a can also contact the end face to be detected, and the second abutting portion 311b can contact the sensor 320. The first abutting portion 311a and the second abutting portion 311b can be end heads made of relatively soft materials. For example, the material of the end heads can be soft end heads such as rubber, polyurethane, or silicone. Thus, it can prevent the two ends of the measuring rod 311 from hard contacting the end face to be detected and the sensor, avoiding knocking and scratching, which can not only protect the end face to be detected but also extend the service life of the sensor 320. Moreover, when the end face to be detected pushes the measuring rod 311 in the direction towards the sensor 320, the first elastic member 312 can also provide an elastic force for the measuring rod 311 in the direction away from the sensor 320. Under the limitation of this acting force, when the sensor 320 receives the force transmitted by the measuring rod 311 and obtains the value of the end face to be detected, that is, when the end face to be detected moves away from the measuring rod 311 in the direction away from the sensor 320, the first elastic member 312 will also drive the measuring rod 311 to move and reset in the direction away from the sensor 320, enabling the second abutting portion 311b of the measuring rod 311 to change from abutting against the sensor 320 to being separated from the sensor 320, thereby restoring the sensor 320 to the zero value of the initial state, and also facilitating the subsequent measurement of the flatness, height, thickness, etc. of the cross-sections of other profiles.

[0046] It should be noted that in the above embodiment, the mounting bracket 330 can also be constructed into any suitable shape according to the shape of the sleeve 1. For example, reference can be made to Figure 3 and Figure 10As shown, when the cross-section of the sleeve 1 is rectangular, the mounting bracket 330 can also be configured as a mounting bracket with a rectangular shape. Multiple first limiting holes 331 on the mounting bracket 330 can also extend along the length direction of the sleeve 1, and the multiple first limiting holes 331 can also be in the Figure 10 matrix array shown for multiple measuring rods 311 to pass through. Alternatively, the cross-section of the mounting bracket 330 can also be circular or polygonal, and any suitable structure can be selected according to the shape of the sleeve 1. The present disclosure does not make specific limitations on this.

[0047] In addition, since the cross-section of the profile of the fixed frame of the photovoltaic panel is small, to improve the accuracy of measuring the cross-section of the profile, the diameter of the measuring rod 311 can be controlled within 4 - 10 mm, and the distance between any two adjacent measuring rods 311 can be controlled within 5 - 12 mm. The diameter of the measuring rod 311 can also be adaptively changed according to different measurement objects. The present disclosure does not make specific limitations on this.

[0048] In some embodiments, referring to Figures 1 to 12 shown, the measuring rod 311 includes a first rod body 3111, a second elastic member 3113, and a second rod body 3112. A first abutting portion 311a is located at one end of the first rod body 3111; one end of the second elastic member 3113 is connected to the end of the first rod body 3111 away from the first abutting portion 311a; one end of the second rod body 3112 is connected to the end of the second elastic member 3113 away from the first rod body 3111, and a second abutting portion 311b is located at the end of the second rod body 3112 away from the second elastic member 3113. In this way, the second elastic member 3113 can provide elastic forces for the first rod body 3111 and the second rod body 3112 at both ends respectively. Moreover, by setting the second elastic member 3113, when the end face to be measured contacts the multiple measuring rods 311, the other ends of all the measuring rods 311 in contact with the end face to be measured can be made to contact the sensor 320 to obtain the comprehensive value of the end face to be measured, that is, referring to Figure 7 shown, in the Figure 7 embodiment given, when the end face to be measured of the workpiece 5 to be detected is an inclined plane, when the workpiece 5 moves along the depth direction of the sleeve 1, it is possible that some of the measuring rods 311 cannot contact the sensor 320, such as Figure 7 , there are three measuring rods 311 in contact with the end face to be measured. Among them, for the two relatively lower measuring rods 311, since the end face to be measured is closer to the sensor 320, the two measuring rods 311 will abut against the sensor 320. At this time, for the upper measuring rod 311, since the end face to be measured is farther from the sensor 320, the measuring rod 311 cannot be made to abut against the sensor 320. If the end face to be measured is measured in this state, the flatness and the data of the height or thickness of the cross-section to be measured cannot be comprehensively obtained. However, if the second elastic member 3113 exists, it canFigure 7 In the example shown, more movement amount is given to the measuring rod 311 by the compression of the second elastic member 3113, and the member 5 to be detected can be continuously pushed to the right until the other ends of all the measuring rods 311 in contact with the end face to be measured all contact the sensor 320. Then, the measurement data of the cross-section to be measured can be comprehensively obtained. And, reference can be made to Figure 7 As shown, since the end face to be measured is an inclined plane, the position of the end face to be measured closer to the sensor 320 will apply a greater force to the sensor 320 through the measuring rod 311, and the position farther from the sensor 320 will apply a smaller force to the sensor 320 through the measuring rod 311. The flatness of the end face to be measured can be judged by judging the magnitude of the force value of the sensor 320.

[0049] It should be noted that, in the above embodiment, the sensor 320 can be constructed into any suitable sensor structure. For example, it can be a force value sensor with a force measuring end existing in the prior art. The second abutting portion 311b can abut against the force measuring end of the force value sensor for force measurement, and the present disclosure will not elaborate too much.

[0050] In addition, in the above embodiment, the second elastic member 3113 can also be constructed into any structural member with an elastic function. For example, the second elastic member 3113 can be a spring, and the two ends of the spring can be respectively connected to the first rod body 3111 and the second rod body 3112, and the present disclosure will not elaborate too much.

[0051] In some embodiments, reference is made to Figures 1 to 12As shown, a second limiting hole 102 penetrating through the inner and outer sides of the sleeve 1 is provided on the side wall of the sleeve 1. A limiting member 110 is provided inside the sleeve 1. The clamping assembly 210 includes a clamping member 211 and a third elastic member 212. The clamping member 211 passes through the second limiting hole 102 and includes a clamping portion 2111 for clamping the component 5 to be detected. The third elastic member 212 is connected between the limiting member 110 and the clamping member 211, and the third elastic member 212 is used to provide a force for the clamping portion 2111 to clamp the component 5 to be detected. In this way, when the component 5 to be detected moves along the depth direction of the sleeve 1, the outer side wall of the component 5 to be detected can be clamped by the clamping member 211, thereby improving the stability of the component 5 to be detected during the detection of the end face, and also improving the accuracy of the detection result. Moreover, when the component 5 to be detected is clamped by the clamping member 211, the third elastic member 212 can also provide an elastic force towards the component 5 to the clamping member 211, so as to be able to clamp the component 5 more firmly through the clamping portion 2111. In addition, the limiting member 110 on the sleeve 1 can also limit the third elastic member 212, so that the third elastic member 212 can always provide a force in the direction of clamping the component 5 to the clamping portion 2111. And the third elastic member 212 can also be constructed as a spring with the same structure as the second elastic member 3113 in the above-mentioned embodiment, and the present disclosure does not limit this.

[0052] In some embodiments, referring to Figures 1 to 12 As shown, the clamping member 211 further includes a main body 2113 passing through the second limiting hole 102 and a convex platform provided at one end of the main body 2113 located inside the sleeve 1. The clamping portion 2111 is the outer surface of the convex platform facing away from the sleeve 1. At least one side wall surface 2112 of the convex platform facing the opening 101 extends obliquely from the main body 2113 towards the outer surface and towards the second end to form a guiding surface. In this way, when the component 5 to be detected enters the sleeve 1, it can slide more smoothly into the sleeve 1 through the obliquely extending guiding surface, that is, the side wall surface 2112, to be clamped by the clamping portion 2111. And during the process of the component 5 to be detected entering the sleeve 1, the main body 2113 will also slide relative to the second limiting hole 102. Under the limiting action of the second limiting hole 102, it can also indirectly stably clamp the component 5 to be detected during the movement of the component 5 to be detected along the sleeve 1.

[0053] The shapes of the second limiting hole 102 and the main body 2113 can be any suitable shapes that can be adapted. For example, referring to Figure 3 As shown, the second limiting hole 102 may include a plurality of rectangular holes and a plurality of special-shaped holes with right-angle bends. The plurality of rectangular holes and the plurality of special-shaped holes with right-angle bends can jointly enclose a rectangular through-hole combination for the main body 2113 to be inserted, thereby improving the stability of the main body 2113 inserted into the second limiting hole 102.

[0054] It should be noted that the number of the sidewall surfaces 2112 can be selected as any appropriate number according to the shape of the clamping member 211. For example, Figure 9 As shown, there may be four sidewall surfaces 2112 that extend from the main body 2113 toward the outer surface and converge in an inclined manner. Alternatively, in an embodiment not shown in the figure, there may be three, five or other numbers of sidewall surfaces 2112, and the present disclosure is not limited thereto.

[0055] In some embodiments, reference Figures 1 to 12 As shown, the number of the limiting member 110 and the third elastic member 212 can also be multiple and one-to-one corresponding, and the multiple third elastic members 212 can jointly provide the clamping force of the clamping portion 2111 to clamp the to-be-detected member 5, thereby clamping the to-be-detected member 5 more stably. For example, you can refer to Figure 1 and Figure 3 As shown, the number of the limiting members 110 and the third elastic members 212 can be four and arranged in a rectangular shape. The four limiting members 110 respectively elastically support the four third elastic members 212, and the four third elastic members 212 provide the clamping force of the clamping part 2111 to clamp the part to be detected 5. It should be noted that the number of four limiting members 110 and the third elastic members 212 provided in the present disclosure is exemplary, and the present disclosure is not limited to this. For example, the number of limiting members 110 and the third elastic members 212 can also be other numbers such as three, five or more.

[0056] In some embodiments, reference Figures 1 to 12 As shown, the clamping assembly 210 further includes a limit plate 213, which is connected to the clamping member 211 and is located outside the sleeve 1. In this way, the limit plate 213 can limit the stroke of the clamping member 211, that is, Figure 1 and Figure 2 As shown, since the third elastic member 212 provides a force for the clamping portion 2111 toward the part to be detected 5, under this connection method, in order to prevent the main body 2113 from being disengaged from the second limiting hole 102 and popping out, the limiting plate 213 can be connected to the bottom of the main body 2113 and located on the outside of the sleeve 1. Under this arrangement, when the main body 2113 is about to be disengaged from the second limiting hole 102, the limiting plate 213 will fit into the outer surface of the sleeve 1, thereby limiting the main body 2113.

[0057] The limiting plate 213 and the main body 2113 can be connected in any suitable manner, for example, Figure 9As shown, a plurality of positioning protrusions 213a may be provided at the edge of the limiting plate 213, and a plurality of grooves 213b may be provided on the main body 2113 for the plurality of positioning protrusions 213a to be inserted one by one. Under this arrangement, the positioning protrusions 213a may be inserted one by one into the grooves 213b to clamp the limiting plate 213 on the main body 2113, so as to improve the stability of the connection between the limiting plate 213 and the main body 2113.

[0058] In some embodiments, reference Figures 1 to 12 As shown, the mounting plate 340 includes a base plate 341, a circuit board 342, and a support plate 343 arranged in sequence. The sensor 320 is disposed on the support plate 343 and electrically connected to the circuit board 342. The base plate 341 is provided with a device switch 3411 and a signal transmitting switch 3412. In this manner, when the measuring rod 311 contacts the surface of the sensor 320, the sensor 320 transmits a pressure signal through the support plate 343 to the circuit board 342, and then transmits the pressure value in the form of a signal to an external data processing mechanism 4, such as a computer, tablet computer, mobile terminal, or server. The method of the sensor transmitting the pressure value to a data processing mechanism 4, such as a computer, by transmitting a signal has been widely used in the prior art and can be transmitted by wired or wireless means. This disclosure will not elaborate on this. The device switch 3411 can freely control the start and stop of the detection device. For example, the device switch 3411 can be connected between an external power supply and the sensor to control the power on and off. In addition, after all the end faces to be tested of the part to be tested 5 are in contact with multiple detection rods 311 and abut against multiple sensors 320, the signal transmitting switch 3412 can be started, and the signal values detected by the multiple sensors 320 can be sent to an external data processing organization 4 such as a computer or server, thereby improving the accuracy of the detection of the end face to be tested. Among them, the signal transmitting switch 3412 is used to control the signal emission of the sensor 320, which is an existing principle and will not be repeated in this disclosure.

[0059] The second aspect of the present disclosure provides a detection device, which includes a data processing mechanism 4 and the detection device mentioned in the above specific embodiments. The data processing mechanism 4 is communicatively connected with multiple sensors 320, and the detection device has all the beneficial effects of the above embodiments. The data processing mechanism 4 can be a computer, tablet computer, mobile terminal or other device that already exists in the prior art.

[0060] This disclosure exemplarily describes the specific operation process of the detection device, which may include the following steps:

[0061] After placing the sleeve 1 properly, orient the end face to be measured of the workpiece 5 to be detected towards the inside of the sleeve 1, insert the workpiece 5 to be detected into the sleeve 1, and turn on the device switch 3411. The workpiece 5 to be detected will gradually push multiple side wall surfaces 2112 and compress the third elastic member 212, driving multiple clamping members 211 to move away from the sleeve 1. As the workpiece 5 to be detected continues to move deeper, the end face to be measured of the workpiece 5 will abut against multiple first abutting portions 311a, and drive the first rod body 3111, the second elastic member 3113, and the second rod body 3112 to move towards the second end. Multiple second abutting portions 311b of the multiple second rod bodies 3112 moving towards the second end will abut against the sensors 320. When the workpiece 5 to be detected is pushed to the preset position, the signal transmitting switch 3412 can be turned on. At this time, multiple sensors 320 will send the pressure given by the measuring rod 311 to the data processing mechanism 4 in the form of signals. The staff can judge whether the end face to be measured meets the standard end face by the values displayed by the data processing mechanism 4, the coordinate points formed by the 3D software, or the model of the end face to be measured restored. For example, whether the flatness meets the flatness requirements of the standard end face. After measuring the end face to be measured of the workpiece 5, the workpiece 5 to be detected can be pulled out of the sleeve 1 towards the first end to complete the measurement of the end face to be measured of the workpiece 5.

[0062] The preferred embodiments of the present disclosure have been described in detail above in conjunction with the accompanying drawings. However, the present disclosure is not limited to the specific details in the above embodiments. Within the scope of the technical concept of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.

[0063] In addition, it should be noted that, in the case of no conflict, the various specific technical features described in the above specific embodiments can be combined in any suitable manner. To avoid unnecessary repetition, the present disclosure will not separately describe various possible combination methods.

[0064] In addition, any combination can be made between various different embodiments of the present disclosure as long as it does not violate the idea of the present disclosure, and it should also be regarded as the content disclosed by the present disclosure.
