[0031] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0032] In order to solve the problem that the measurement result of the length, width and other geometric parameter data of the crystal bar is not accurate and stable in the prior art, the utility model provides a geometric parameter detection device.

[0033] Please refer to Figures 1 to 8 The technical scheme of the utility model provides a geometric parameter detection device, which comprises a mounting frame body 10, a positioning structure 20, a pushing structure 30 and a measuring assembly 40. The positioning structure 20 is arranged on the mounting frame body 10, and at least part of the positioning structure 20 is movably arranged. The pushing structure 30 is arranged on the mounting frame body 10, and at least part of the pushing structure 30 is movably arranged towards the positioning structure 20, so as to push the component to be measured to the positioning structure 20 and fix it through the positioning structure 20. The measuring assembly 40 is movably arranged on the mounting frame body 10, and comprises a measuring sensor for collecting parameter signals of any two end faces of the component to be measured respectively and outputting the parameter signals into parameter information. The parameter information comprises the length, width and thickness of the component to be measured, and the perpendicularity or taper between any two end faces of the component to be measured.

[0034] The technical scheme of the utility model provides a geometric parameter detection device, which comprises a mounting frame body 10, a positioning structure 20, a pushing structure 30 and a measuring assembly 40. The positioning structure 20 is arranged on the mounting frame body 10, and at least part of the positioning structure 20 is movably arranged. The pushing structure 30 is arranged on the mounting frame body 10, and at least part of the pushing structure 30 is movably arranged towards the positioning structure 20, so as to push the component to be measured to the positioning structure 20 and fix it through the positioning structure 20. The measuring assembly 40 is movably arranged on the mounting frame body 10, and comprises a measuring sensor for collecting parameter signals of any two end faces of the component to be measured respectively and outputting the parameter signals into parameter information. The parameter information comprises the length, width and thickness of the component to be measured, and the perpendicularity or taper between any two end faces of the component to be measured.

[0035] In the present embodiment, the component to be measured is a crystal bar.

[0036] As shown in Figure 1 and Figure 2 , the positioning structure 20 comprises a clamping assembly 21 and a centering assembly 22; the clamping assembly 21 is arranged on the mounting frame body 10 for clamping the end of the component to be measured; the centering assembly 22 is arranged on the mounting frame body 10 along the extension direction of the component to be measured, and comprises two centering components 220 movably arranged opposite to each other, which are used to abut against the opposite sides of the component to be measured respectively, so as to fix the component to be measured on the mounting frame body 10 along the horizontal direction.

[0037] In this way, through the combined use of the clamping assembly 21 and the centering assembly 22, the component to be measured can be accurately positioned and fixed before measurement. The clamping of the end of the component to be measured by the clamping assembly 21 and the fixation of the component to be measured along the horizontal direction by the centering assembly 22 jointly reduce any slight movement or deformation of the component to be measured during measurement, thereby improving the accuracy and consistency of the measurement results. The two centering components 220 of the centering assembly 22 can movably contact the two sides of the component to be measured, and this design can adapt to components to be measured of different size specifications while ensuring the stability of the component to be measured during measurement, avoiding inaccurate positioning due to size differences. Moreover, the design of the positioning structure 20 makes it easy to integrate with an automatic control system, which can accurately control the clamping and centering processes, realize a fast, efficient and stable automatic detection process, and reduce the error and labor intensity of manual operation.

[0038] As shown in Figure 4As shown, the clamping assembly 21 includes a mounting seat 210 and two clamping plates 211; the mounting seat 210 is provided on the mounting frame body 10; the two clamping plates 211 are movably provided on the mounting seat 210, and a plurality of first rollers 212 are respectively provided on the ends of the two clamping plates 211 away from the mounting seat 210, the outer circumferential surfaces of the plurality of first rollers 212 are respectively used to contact the end of the component to be measured to clamp the component to be measured. Among them, the mounting seat 210 is provided with driving members such as air cylinders or motors connected with the two clamping plates 211 respectively. In this way, the plurality of first rollers 212 are used to contact the end of the component to be measured for clamping, which can significantly reduce the damage to the component to be measured such as a crystal bar compared with the traditional rigid clamping mode. And the contact mode of the first roller 212 is more gentle, which avoids the surface scratches or deformation caused by the hard clamp. The relative movement of the two clamping plates 211 is driven by the air cylinder, so that the clamping assembly 21 can adapt to components to be measured of different sizes. By adjusting the distance between the two clamping plates 211, it can ensure that the component to be measured remains stable during the measurement process, reducing measurement errors. The first roller 212 contacts the component to be measured, and the rolling friction is smaller than the sliding friction, which reduces the friction and wear between the components during clamping, prolonging the service life of the equipment.

[0039] As shown in Figure 5 The positioning structure 20 further includes a limiting assembly 23 movably provided on the mounting seat 210 in the direction towards the component to be measured and located between the two clamping plates 211, the limiting assembly 23 includes a fixed seat 230 and two limiting protrusions 231 provided on the fixed seat 230, the two limiting protrusions 231 are used to be connected with the two connecting recesses on the component to be measured respectively to limit the component to be measured.

[0040] In this way, through the precise connection of the limiting protrusions 231 of the limiting assembly 23 with the connecting recesses on the component to be measured, the position of the component to be measured during the detection process can be absolutely fixed, thereby improving the measurement accuracy. This precise alignment avoids measurement errors caused by inaccurate positioning. Moreover, the limiting assembly 23, as part of the positioning structure 20, works together with the clamping assembly 21 and the centering assembly 22 to further enhance the positioning and fixing ability of the component to be measured such as a crystal bar. Even after the initial positioning provided by the clamping plates 211 and the centering assembly 220, the limiting assembly 23 can ensure that the component to be measured will not deviate from its position due to external forces (such as the contact force of the measuring assembly 40) or vibration. At the same time, the use of the limiting assembly 23 reduces the clamping force required by the clamping assembly 21, because the cooperation of the limiting protrusions 231 and the connecting recesses provides additional support and limitation, avoiding unnecessary damage to the crystal bar caused by excessive clamping force.

[0041] As shown in Figure 3As shown, the centering component 220 includes a moving plate 2201 and a plurality of second rollers 2202; the moving plate 2201 extends along the direction of the pushing structure 30 towards the clamping assembly 21; the plurality of second rollers 2202 are respectively arranged on the moving plate 2201 along the extension direction of the moving plate 2201, and the outer circumferential surfaces of the plurality of second rollers 2202 are respectively used to contact the side of the component to be measured, so as to clamp the middle part of the component to be measured. Wherein, the mounting frame body 10 is provided with driving members such as air cylinders or motors respectively drivingly connected with the two moving plates 2201.

[0042] In this way, the plurality of second rollers 2202 respectively contact the side of the component to be measured, which can ensure the accurate centering of the component to be measured during movement. This design utilizes the interval distribution of the second rollers 2202 along the extension direction of the moving plate 2201, which can uniformly apply force to the side of the component to be measured, so as to accurately align and position the component to be measured in the horizontal direction, avoiding the deviation of measurement. Moreover, the second rollers 2202 contact the component to be measured, and the friction is reduced by rolling instead of sliding, which can reduce the wear between the component to be measured and the equipment, prolong the service life of the equipment, and reduce the surface damage of the component to be measured such as the crystal bar. At the same time, by adjusting the positions of the second rollers 2202 on the moving plate 2201, the centering component 220 can adapt to components to be measured of different sizes, improve the flexibility and versatility of the equipment, so that the same device can measure crystal bars of multiple specifications, and reduce the need to replace or adjust the detection equipment.

[0043] Specifically, the mounting frame body 10 is provided with a mounting hole 11 between the two centering components 220, and the mounting frame body 10 is provided with support pads 12 respectively on the opposite sides of the opening edge of the mounting hole 11, and the component to be measured is placed on the support pads 12. The pushing structure 30 includes a main pushing assembly 31, at least part of the main pushing assembly 31 is arranged movably in the mounting hole 11 and in the direction towards the clamping assembly 21, so as to contact the end of the component to be measured away from the positioning structure 20 and push the component to be measured towards the clamping assembly 21. The above-mentioned arrangement provides a stable support point for the component to be measured by the support pads 12, and the main pushing assembly 31 is partially arranged in the mounting hole 11 and can smoothly move in the direction towards the clamping assembly 21, which ensures the smoothness of the component to be measured during pushing, avoids sudden impact or vibration, helps to protect the crystal bar from damage, and further realizes the pushing of the component to be measured to the positioning structure 20, so as to facilitate the subsequent fixation of the component to be measured.

[0044] As Figure 6As shown, the main pushing assembly 31 includes a first guide rail seat 310 and a pushing plate 311. The first guide rail seat 310 is arranged on the mounting frame body 10. The pushing plate 311 is arranged in the mounting hole 11 and is movably arranged on the first guide rail seat 310 in a direction towards the clamping assembly 21. The side of the pushing plate 311 facing the component to be tested is provided with a buffer pad 312, which is used to contact the component to be tested, so as to push the component to be tested to move close to the clamping assembly 21. The first guide rail seat 310 is provided with a driving member such as a cylinder or a motor which is drivingly connected with the pushing plate 311. In this way, the first guide rail seat 310 provides guidance and support for the pushing plate 311, ensuring that the pushing plate 311 moves smoothly in a straight line, avoiding swinging or deviation during pushing, which helps to improve the accuracy and stability of the component to be tested during positioning. The use of the buffer pad 312 can significantly reduce the hard impact when the pushing plate 311 contacts the component to be tested, thereby reducing the risk of damage to the surface of the crystal bar. The buffer pad 312 can absorb part of the impact force, so that the component to be tested moves to the positioning structure 20 in a more gentle manner.

[0045] Specifically, the pushing structure 30 further includes a side pushing assembly 32, at least part of which is movably arranged in a direction towards the positioning structure 20, for contacting the opposite sides of the component to be tested respectively, so as to drive the component to be tested to move towards the clamping assembly 21. In this way, the side pushing assembly 32 can exert force on both sides of the component to be tested, helping it to be more accurately centered and moved towards the clamping assembly 21. This double-sided pushing method can significantly improve the accuracy of the component to be tested when it reaches the positioning structure 20, reducing positional deviation, compared with using only the main pushing assembly 31 for single-direction pushing. Moreover, through the cooperation of the side pushing assembly 32 and the main pushing assembly 31, the component to be tested can be quickly positioned at the clamping assembly 21, reducing the additional adjustment time required due to inaccurate positioning, speeding up the detection process, and improving production efficiency. At the same time, the side pushing assembly 32 is easy to integrate with an automatic control system, and can realize accurate control of the pushing force, speed and position, reducing the skill requirements of the operator and improving the automation level of the detection process.

[0046] As Figure 7As shown, the side pushing assembly 32 includes a second guide rail seat 320, a support frame 321, and a clamping component 322; the second guide rail seat 320 is arranged on the mounting frame body 10; one end of the support frame 321 is connected with the second guide rail seat 320 and is movably arranged in a direction towards the clamping assembly 21; the clamping component 322 includes a driving component 3220 and two clamping plates 3221, the driving component 3220 is connected with the other end of the support frame 321, the two clamping plates 3221 are respectively connected with the driving component 3220 and are movably arranged oppositely, and the opposite sides of the two clamping plates 3221 are respectively provided with elastic members 3222 for contacting the side of the component to be measured, so as to clamp the component to be measured by driving the two clamping plates 3221 by the driving component 3220, and drive the component to be measured to the position close to the clamping assembly 21 by the clamping component 322. The driving component 3220 is a gas cylinder or a motor.

[0047] The above arrangement, the two oppositely movable clamping plates 3221 can clamp the component to be measured from both sides, and cooperate with the driving component 3220 to accurately and stably move the component to be measured in the direction towards the clamping assembly 21. This bidirectional positioning method improves the positioning accuracy and stability compared with unidirectional pushing. And the elastic members 3222 arranged on the clamping plates 3221 can provide flexible support when contacting the component to be measured, reducing the damage caused by hard contact. Especially when measuring sensitive materials such as crystal rods, this design can significantly reduce the risk of surface scratching or deformation. At the same time, the design of the clamping component 322 can adapt to different sizes and shapes of the component to be measured, and by adjusting the relative position of the clamping plates 3221 and the pushing force of the driving component 3220, it ensures that different components can be effectively positioned and pushed.

[0048] As shown, Figure 8 The measurement assembly 40 includes a third guide rail seat 41, a camera component 42, and two measurement components 43; the third guide rail seat 41 is arranged on the mounting frame body 10; the camera component 42 is movably arranged on the third guide rail seat 41 in a direction from the pushing structure 30 to the positioning structure 20, so as to align any two end faces of the component to be measured; the two measurement components 43 are respectively arranged on both sides of the camera component 42, and the measurement component 43 includes a measurement sensor, a probe, and a data processing unit, the measurement sensor transmits the parameter signal of any two end faces of the component to be measured detected by the probe to the data processing unit, and obtains the parameter information of the component to be measured after processing and output by the data processing unit. The third guide rail seat 41 is provided with a driving member such as a gas cylinder or a motor drivingly connected with the camera component 42.

[0049] In this way, the camera component 42 moves along the third guide rail base 41, and can automatically align any two end faces of the component to be measured, ensuring that the measurement sensor works at the correct measurement position. This automatic alignment mechanism reduces human error and improves the efficiency and consistency of measurement. The high-speed response of the measurement sensor when detecting the crystal bar is used as a parameter signal acquisition, the high-speed latching of the current position function of the servo probe and the high-precision positioning position of the servo encoder itself of the data processing unit are used to ensure the accuracy and real-time performance of the signal feedback, and finally the actual parameter information of the detected crystal bar is calculated and displayed on the display screen. The entire process realizes the automation of measurement, reduces manual operation, and reduces the difficulty and error rate of operation. The detection precision, efficiency and stability of the geometric parameters of the crystal bar and other components to be measured are greatly improved, and the influence of the environment on the measurement is reduced.

[0050] From the above description, it can be seen that the embodiments of the utility model realize the following technical effects:

[0051] The geometric parameter detection device comprises a mounting frame body 10, a positioning structure 20, a pushing structure 30 and a measurement assembly 40. The positioning structure 20 is arranged on the mounting frame body 10, and at least part of the positioning structure 20 is movably arranged. The pushing structure 30 is arranged on the mounting frame body 10, and at least part of the pushing structure 30 is movably arranged towards the positioning structure 20, so as to push the component to be measured to move to the positioning structure 20 and fix the component to be measured by the positioning structure 20. The measurement assembly 40 is movably arranged on the mounting frame body 10, and comprises a measurement sensor for respectively acquiring parameter signals of any two end faces of the component to be measured and outputting the parameter signals into parameter information. The parameter information comprises the length, width and thickness of the component to be measured, and the perpendicularity or taper between any two end faces of the component to be measured. In this way, the positioning structure 20 can ensure that the component to be measured is accurately positioned and stably fixed before measurement, reduces the positional deviation in the measurement process, and thus improves the accuracy and stability of measurement. The measurement sensor in the measurement assembly 40 can obtain more accurate position information of each end face by emitting laser to the component to be measured and receiving the reflected signal, improve the detection accuracy, and thus more accurately calculate the geometric parameters such as length, width, thickness and the perpendicularity or taper between the end faces. The multifunctional integration is realized, the need for multiple separate measurement devices is reduced, the detection efficiency and flexibility are improved, and thus the problem that the measurement results of the geometric parameter data such as length and width of the crystal bar are not accurate and stable in the prior art is solved, the need for multiple detection of the component to be measured is reduced, and the production cost is reduced.
