Description

Technical Field

[0001] The utility model belongs to the field of film detection equipment, in particular to an automatic alignment anti-pinch film sample elongation detection device. Background Art

[0002] When a batch of products is produced, the production enterprise of film materials needs to test the elongation at break (the elongation at break usually refers to the ratio of the displacement of the sample to the original length at break) of the batch of products to verify whether the film products have reached the predetermined factory quality. The usual testing method is to clamp the two ends of the film sample with a clamp and then stretch the film sample. When the clamp clamps the film sample, it is necessary to manually send the film sample into the clamping range of the clamp. In order to ensure the clamping force of the clamp, the clamp usually uses a cylinder as a driving device. Manual sample delivery has the safety hazard of hand clamping. At the same time, when testing the film sample, the placement direction of the film sample needs to be consistent with the stretching direction of the test to ensure the accuracy of the test value of the elongation at break. The film to be tested is usually a flexible material, and the manual sample delivery method cannot accurately ensure the placement direction of the film sample. Therefore, it is necessary to provide an automatic alignment and anti-clamping film sample elongation test device that can automatically align the film sample and avoid accidentally clamping the staff. Utility Model Content

[0003] The utility model aims to provide an automatic alignment anti-pinch film sample elongation testing device to solve the potential safety hazard of hand pinching in manual sample delivery. At the same time, when testing the film sample, the placement direction of the film sample needs to be consistent with the stretching direction of the test to ensure the accuracy of the test value of the breaking elongation rate. The film to be tested is usually a flexible material, and the manual sample delivery method cannot accurately ensure the technical problem of the accurate placement direction of the film sample.

[0004] To achieve the above purpose, the specific technical solution of the utility model is as follows:

[0005] An automatic alignment anti-pinch film sample elongation detection device includes a base, a lifting platform and a slider, wherein the lifting platform is installed to be lifted and lowered with the base, and the slider is installed to be slidably with the base, and a clamp is provided on the opposite surface of the lifting platform and the slider, and the clamp is provided with an infrared sensor component and a camera module, and the sensing position of the infrared sensor component matches the clamping position of the clamp, and the shooting position of the camera module matches the clamping position of the clamp. Through such a design, when the staff is performing the sample delivery operation, the infrared detection component will sense the clamping position of the clamp in real time, and when the staff's limbs are detected in the clamping position, the clamp will stop the clamping action. When both ends of the film sample are clamped, the camera module will shoot the film from the stretching direction of the film sample, and analyze the shape of the film sample in the captured picture to determine whether the film sample is in the correct position.

[0006] Furthermore, the lifting platform and the base are installed in cooperation with each other through a lifting cylinder, and the slider and the base are installed in cooperation with each other through a sliding cylinder. With such a design, the lifting cylinder is used for tensile testing of film samples, and the sliding cylinder is used for driving the slider to slide, thereby realizing the horizontal movement of the fixture.

[0007] Furthermore, the clamp includes a base, a U-shaped seat, a clamping block and a driving cylinder. The base is fixedly connected to the slider or the lifting platform, the U-shaped seat is installed in cooperation with the base, and there are two groups of clamping blocks and driving cylinders, which are installed in cooperation with the support arms of the U-shaped seat respectively. The two clamping blocks are respectively arranged on the opposite surfaces of the two support arms, and the driving cylinder drives the clamping blocks to extend and retract. With such a design, the driving cylinder is the power source of the clamping block, which is extended through the two opposite sliders on the U-shaped seat to clamp the film sample.

[0008] Furthermore, the base is provided with a notch, a bearing is arranged in the notch, a rotating shaft is fixed at the bottom of the U-shaped seat, the rotating shaft is rotatably assembled with the bearing, and the end of the rotating shaft extending from the bearing is matched and connected with the power source in the slider. With such a design, some irregular film samples need to be clamped by the rotating clamp, and the clamp can rotate with the power source in the slider to align the irregular film samples and perform the clamping operation.

[0009] Furthermore, the infrared sensor assembly includes a fixed mounting plate, a rotating mounting plate and an infrared sensor, the fixed mounting plate is fixedly mounted on the U-shaped seat, the rotating mounting plate is mounted in cooperation with the fixed mounting plate through a hinge structure, and the infrared sensor is mounted in cooperation with the rotating mounting plate. With such a design, when the rotating mounting plate is erected in a vertical state, the detection direction of the infrared sensor is at the same height as the clamping position of the clamping block, and the detection direction is facing the clamping position.

[0010] Furthermore, the camera module is arranged at the bottom of the U-shaped groove of the U-shaped seat. With such a design, the film sample is usually rectangular, and the side width of the film sample in the stretching direction is measured and recorded before testing. After the film sample is clamped by the clamp, the film sample is photographed in the stretching direction, and the overall length of the film sample in the photographed picture is measured. The two measurement results are compared to determine whether the film sample is clamped accurately.

[0011] Furthermore, the clamping surface of the clamping block is also provided with a friction-increasing structure.

[0012] The beneficial effects of the utility model are as follows: when the staff is delivering the sample, the infrared detection component will sense the clamping position of the clamp in real time, and when the staff's limbs are detected in the clamping position, the clamp will stop clamping. When both ends of the film sample are clamped, the camera module will shoot the film from the stretching direction of the film sample, and analyze the shape of the film sample in the captured picture to determine whether the film sample is in the correct position.
