Description

Technical Field

[0001] The utility model relates to the technical field of parameter measurement of flexible clamps, in particular to a parameter measurement device of a flexible clamp. Background Art

[0002] As the manufacturing industry develops towards high precision and high quality, the requirements for the processing and assembly accuracy of parts are constantly increasing. Flexible fixtures are important tools for fixing and positioning workpieces during processing and assembly. The accuracy of their parameters directly affects the quality and production efficiency of products. Flexible manufacturing systems can quickly adapt to the production needs of different products, and flexible fixtures are one of the key factors in achieving this flexibility. In order to ensure the efficient operation of flexible manufacturing systems, it is necessary to measure and monitor the parameters of flexible fixtures in real time and accurately.

[0003] Existing automated rod unloading devices mostly use a robotic arm to unload the rods. The robotic arm structures used are basically similar, simple and practical. However, due to the uneven thickness and surface roughness of polysilicon rods, the clamping between the robotic arm clamp and the polysilicon rods is mostly line contact or point contact, resulting in the robotic arm clamp not being firmly clamped, and the polysilicon rods and the clamps are prone to relative sliding, causing the robotic arm clamp material to scratch the polysilicon rods, contaminating the polysilicon rods, and ultimately resulting in a significant gap in the appearance quality of polysilicon products compared with foreign companies' products;

[0004] The existing patent (Announcement No.: CN208826401U) is a flexible clamp that effectively improves the fit between the contact layer and the silicon rod by setting an elastic pad layer in each clamping plate, and minimizes relative sliding between the silicon rod and the contact layer. It can well adapt to silicon rods of different thicknesses and surface roughness, and solves the problem of weak clamping of existing robotic arm claws and PU contamination of polysilicon by the claws.

[0005] In response to the above problems, the existing patent provides a solution. When the existing flexible clamp parameter measurement device measures the clamping force of the flexible clamp, when the flexible clamp applies clamping force to the object to be measured, the pressure signal is converted into an electrical signal through the pressure sensor and transmitted to the subsequent processing system. However, when measuring the object to be measured, its unstable supporting point may cause the clamp to fail to achieve the expected measurement state during the measurement, resulting in the force measurement value of certain parts being too large or too small, causing the initial conditions of the measurement to deviate, affecting the accuracy of the overall measurement result.

[0006] Therefore, a parameter measurement device for a flexible fixture is proposed. Utility Model Content

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-5 , the utility model provides a technical solution:

[0028] A parameter measuring device for a flexible fixture comprises a base 1, a fixed plate 2 is fixedly connected to the left side of the top of the base 1, a groove 3 is provided inside the fixed plate 2, an auxiliary component 4 is arranged inside the groove 3, the auxiliary component 4 comprises a motor body 401 bolted to the rear side of the fixed plate 2, an output end of the motor body 401 passes through the rear side of the fixed plate 2, both sides of the top of the base 1 are provided with a slide groove 5, and a measuring component 6 is arranged inside the slide groove 5;

[0029] The measuring component 6 includes a support plate 601 slidably connected to the inside of the slide groove 5, a flexible clamp body 602 is bolted to the top of the support plate 601, a pressure sensor 603 is arranged on the outside of the flexible clamp body 602, a placement block 604 is fixedly connected to the top of the base 1, an electric telescopic rod 605 is bolted to the top of the placement block 604, the output end of the electric telescopic rod 605 is bolted to the right side of the flexible clamp body 602, a protective shell 606 is bolted to the top of the placement block 604, and a displacement sensor 607 is arranged inside the protective shell 606.

[0030] In this embodiment: by starting the electric telescopic rod 605, the output end of the electric telescopic rod 605 pushes the flexible clamp body 602 and the support plate 601 to move toward the object to be measured, and then the flexible clamp body 602 applies a clamping force to the object to be measured. At this time, the pressure sensor 603 starts to work to measure the magnitude of the clamping force. At the same time, the displacement sensor 607 also starts to work to measure the displacement change of the flexible clamp body 602 during the clamping process. Then the pressure sensor 603 and the displacement sensor 607 transmit the measured data to the subsequent processing system for data processing and analysis. After the measurement is completed, the electric telescopic rod 605 drives the flexible clamp body 602 and the support plate 601 to slide inside the slide groove 5 to return to their original position. Compared with the existing parameter measurement device of the flexible clamp, it can accurately measure parameters such as the clamping force and displacement of the flexible clamp, providing reliable data support for the performance evaluation and optimization of the clamp.

[0031] Specifically, Figure 3 , Figure 5 As shown, the output end of the motor body 401 is bolted with a bidirectional threaded rod 402, the front side of the bidirectional threaded rod 402 is rotatably connected to the front side of the inside of the groove 3, the outer side of the bidirectional threaded rod 402 is threadedly connected to a connecting block 403, and the outer side of the connecting block 403 is slidably connected to the inner side of the groove 3.

[0032] Specifically, Figure 3 , Figure 5 As shown, a clamping plate 404 is fixedly connected to the right side of the connecting block 403 , and an auxiliary spring 405 is bolted to the inner side of the clamping plate 404 .

[0033] Specifically, Figure 3 , Figure 5 As shown, the outer side of the auxiliary spring 405 is fixedly connected with an auxiliary plate 406, the inner side of the auxiliary plate 406 is slidably connected with the outer side of the clamping plate 404, and the inner side of the auxiliary plate 406 is bonded with a buffer pad 407, which is made of rubber.

[0034] In this embodiment: by starting the motor body 401, the output end of the motor body 401 drives the bidirectional threaded rod 402 to rotate, and then the rotation of the bidirectional threaded rod 402 causes the connecting block 403 threadedly connected to its outer side to move, so that the movement of the connecting block 403 drives the clamping plate 404 to move, and then the auxiliary spring 405 and the auxiliary plate 406 on the inner side of the clamping plate 404 move accordingly. When the clamping plate 404 moves to a suitable position, the object to be measured is clamped and fixed to ensure that the supporting point of the object to be measured is stable. After the measurement is completed, the bidirectional threaded rod 402 is driven to rotate in the opposite direction through the reverse rotation of the electric body, driving the connecting block 403 and the clamping plate 404 to release the clamping and fixing of the object to be measured. The parameter measurement device relative to the existing flexible clamp can effectively solve the problem of unstable supporting point of the object to be measured, so that the clamp reaches the expected measurement state during measurement, ensures that the initial conditions of the measurement are accurate, thereby improving the accuracy of the overall measurement result.

[0035] Specifically, Figure 1 , Figure 4 As shown, the top of the fixed plate 2 is fixedly connected to a limit plate 7 , and the right side of the limit plate 7 is bolted with a laser sensor 8 .

[0036] Specifically, Figure 5 As shown, a sliding groove 9 is provided inside the auxiliary plate 406 , a sliding block 10 is slidably connected inside the sliding groove 9 , and the inner side of the sliding block 10 is fixedly connected to the outer side of the clamping plate 404 .

[0037] In this embodiment: by setting a limit plate 7 and a laser sensor 8, during the measurement process, the laser sensor 8 can use a laser beam to measure the distance between the object and the sensor, calculate the distance between the object and the sensor by measuring the reflection time or phase change of the light beam, and can accurately detect and locate the object to be measured, thereby improving the measurement precision and accuracy. By setting a sliding groove 9 and a sliding block 10, the stability of the auxiliary plate 406 during the movement can be ensured, so that it can better cooperate with the clamping plate 404 to stably clamp the object to be measured.

[0038] Specifically, Figure 4 As shown, a placement groove 11 is provided on the top of the base 1 , and the placement groove 11 is located at the bottom of the output end of the laser sensor 8 .

[0039] Specifically, Figure 1 , Figure 4 As shown, the base 1 is fixedly connected with supporting legs 12 on all sides of the bottom, and the bottom of the supporting legs 12 is bonded with anti-skid pads 13, which are made of rubber.

[0040] In this embodiment: by providing a placement groove 11, it is convenient to place the object to be measured, which helps to improve the convenience and efficiency of measurement. By providing support legs 12 and anti-slip pads 13, the stability of the measuring device can be enhanced to prevent sliding or shaking during the measurement process, thereby ensuring the accuracy of the measurement results. At the same time, the anti-slip pads 13 can also reduce the wear between the device and the placement surface.

[0041] Working principle: in the process of using the parameter measuring device of the flexible clamp, the object to be measured is placed inside the placement slot 11, and then the laser sensor 8 can use a laser beam to measure the distance between the object and the sensor. The distance between the object and the sensor is calculated by measuring the reflection time or phase change of the light beam, and the object to be measured can be accurately detected and positioned. Then the motor body 401 is started, so that the output end of the motor body 401 drives the bidirectional threaded rod 402 to rotate, and then the rotation of the bidirectional threaded rod 402 causes the connecting block 403 threadedly connected to its outer side to move, so that the movement of the connecting block 403 drives the clamp 404 to move, and then the auxiliary spring 405 and the auxiliary plate 406 on the inner side of the clamp 404 move accordingly. When the clamp 404 moves to the appropriate position, the object to be measured is clamped and fixed to ensure that the support point of the object to be measured is stable, and the electric telescopic rod 605 is started, so that the output end of the electric telescopic rod 605 pushes the flexible clamp body 602 and the support plate 601 move toward the object to be measured, and then the flexible clamp body 602 applies a clamping force to the object to be measured. At this time, the pressure sensor 603 starts to work to measure the magnitude of the clamping force. At the same time, the displacement sensor 607 also starts to work to measure the displacement change of the flexible clamp body 602 during the clamping process. Then the pressure sensor 603 and the displacement sensor 607 transmit the measured data to the subsequent processing system for data processing and analysis, so as to solve the problem that the parameter measurement device of the existing flexible clamp is in measuring the clamping force of the flexible clamp. When the flexible clamp applies a clamping force to the object to be measured, the pressure signal is converted into an electrical signal through the pressure sensor 603 and transmitted to the subsequent processing system. However, when measuring the object to be measured, its unstable support point may cause the clamp to fail to reach the expected measurement state during the measurement, resulting in the force measurement value of some parts being too large or too small, causing the initial conditions of the measurement to deviate, affecting the accuracy of the overall measurement result.

[0042] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
