Description

Technical Field

[0001] This utility model relates to the field of paint film adhesion testing technology, and in particular to a paint film adhesion tester that is easy to operate. Background Technology

[0002] Current paint film adhesion testers include a support plate and a scribing mechanism located above the processing surface. The scribing mechanism activates a scribing needle at the bottom, which rotates and scribes across the sample plate on the support plate. By adjusting the position of the scribing mechanism upwards to create an interval with the support plate, the sample plate coated with paint film can be placed on the support plate. Then, the scribing mechanism is moved downwards so that the tip of the scribing needle presses onto the sample plate. However, the scribing mechanism is often equipped with a weight to increase the pressure of the scribing needle to ensure the test effect. This makes moving the scribing mechanism relatively laborious and requires the installation of positioning parts to fix the scribing mechanism. The placement and removal of the sample plate is cumbersome and the operation efficiency is low.

[0003] To address the aforementioned issues, prior art CN220380974U discloses a conveniently operated paint film adhesion tester, comprising a base body with a test platform and a circular marking mechanism. The top surface of the test platform has a support plate, and a sample interval is provided between the support plate and the circular marking mechanism. The top surface of the test platform also has a movable groove, one side of which connects to the side of the test platform to form an inlet / outlet. The support plate is horizontally positioned at the top of the movable groove. A deflection shaft is located at one end of the support plate away from the inlet / outlet, and a drive column is hinged to the other end. The deflection shaft is hinged to the inner wall of the movable groove. A vertically downward extending support column is located on the side of the drive column. Support seats are located on both sides of the inlet / outlet, with the top surface of the support seat fitting against the bottom surface of the support column. This design allows the support plate to retract into the movable groove by rotating the drive column, creating more space for sample placement and removal. Moving the support plate is less strenuous, operation is faster, and testing efficiency is improved.

[0004] However, in the aforementioned prior art, since two sample plates press down on both ends of the sample respectively, the sample is not positioned equally, which affects the detection efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide a paint film adhesion tester that is easy to operate, which solves the technical problem in the prior art where two sample plates press down on both ends of the sample respectively, resulting in unequal positioning of the sample and affecting the testing efficiency.

[0006] To achieve the above objectives, this utility model employs a conveniently operated paint film adhesion tester, comprising a base, a circular marking mechanism, a support plate, a collection mechanism, and a positioning and clamping component. The positioning and clamping component includes a bracket, a servo motor, a rotating shaft, a transmission disk, two support arms, two clamping arms, and a limiting component. The circular marking mechanism, the support plate, and the collection mechanism are respectively mounted on the base. The support plate is fixedly connected to the collection mechanism and located at one end of the collection mechanism. The bracket, the two clamping arms, and the limiting component are respectively mounted on the base. The servo motor is fixedly connected to the bracket and located at one end of the bracket.

One end of each clamping arm is rotatably connected to the corresponding support arm and located at one end of the corresponding support arm. The other end of each clamping arm is slidably connected to the limiting component and located at one end of the limiting component.

[0007] The transmission disc includes a connecting shaft and a disc body. One end of the connecting shaft is fixedly connected to the rotating shaft and located at one end of the rotating shaft. The other end of the connecting shaft is fixedly connected to the disc body and located at one end of the disc body.

[0008] Each of the support arms includes an arm body and two support rods, one of which is rotatably connected to the disc body and located at one end of the disc body, and the two support rods are rotatably connected to the arm body and symmetrically arranged at one end of the arm body.

[0009] Each clamping arm includes a clamping plate and a slider. The slider is fixedly connected to the clamping plate and located at one end of the clamping plate. The clamping plate is rotatably connected to the corresponding support rod and located at one end of the corresponding support rod.

[0010] The limiting component includes two fixing blocks and a limiting rod. The two fixing blocks are fixedly connected to the limiting rod and are symmetrically arranged at one end of the limiting rod.

[0011] This utility model discloses a conveniently operated paint film adhesion tester. A bracket, two clamping arms, and a limiting component are respectively mounted on a base. A servo motor is fixedly connected to the bracket and located at one end of the bracket. A rotating shaft is fixedly connected to the output end of the servo motor.

The servo motor drives the transmission disk to rotate via the rotating shaft. The transmission disk drives the two support arms to rotate. The two support arms drive the two clamping arms to move relative to each other via the limiting component, thereby positioning and clamping the sample on the support plate. This method effectively solves the problem that the two sample pressing plates pressing the two ends of the sample separately cause unequal positioning of the sample, affecting the testing efficiency.

The transmission disk is fixedly connected to the rotating shaft 107 and is located at one end of the rotating shaft 107. The two support arms are rotatably connected to the transmission disk and are symmetrically disposed at one end of the transmission disk. One end of each clamping arm is rotatably connected to the corresponding support arm and located at one end of the corresponding support arm.

The circular drawing mechanism 102 and the collecting mechanism 104 are provided by the prior art. The material to be inspected is placed on the carrier plate 103. The servo motor 106 drives the transmission disk to rotate through the rotating shaft 107. The transmission disk drives the two support arms to rotate. The two support arms drive the two clamping arms to move relative to each other through the limiting component, thereby positioning and clamping the sample on the carrier plate 103. This solves the problem that the two sample pressing plates press the two ends of the sample respectively, resulting in unequal positioning of the sample and affecting the detection efficiency.

[0021] The transmission disc includes a connecting shaft 108 and a disc body 109. One end of the connecting shaft 108 is fixedly connected to the rotating shaft 107 and is located at one end of the rotating shaft 107.

The two support rods 111 are rotatably connected to the arm body 110 and are symmetrically arranged at one end of the arm body 110. The disc body 109 drives the arm body 110 to rotate through the corresponding support rods 111.

[0023] Meanwhile, each clamping arm includes a clamping plate 112 and a slider 113. The slider 113 is fixedly connected to the clamping plate 112 and is located at one end of the clamping plate 112. The clamping plate 112 is rotatably connected to the corresponding support rod 111 and is located at one end of the corresponding support rod 111.

[0024] In addition, the limiting assembly includes two fixing blocks 114 and a limiting rod 115. The two fixing blocks 114 are fixedly connected to the limiting rod 115 and are symmetrically arranged at one end of the limiting rod 115. The limiting rod 115 is mounted on the two fixing blocks 114.

[0025] Using the paint film adhesion tester of this embodiment, which is easy to operate, the material to be inspected is placed on the support plate 103 during use. The servo motor 106 drives the rotating shaft 107 to rotate, the rotating shaft 107 drives the connecting shaft 108 to rotate, and the connecting shaft 108 drives the disc 109 to rotate. The disc 109 drives the two arms 110 to rotate through the two corresponding support rods 111.

This solves the problem that the two sample pressing plates press the two ends of the sample respectively, resulting in unequal positioning of the sample and affecting the testing efficiency.
