Description

Technical Field

[0001] This utility model specifically relates to a device for testing the strength of a sulfide glass film. Background Technology

[0002] Chalcogenide glasses, due to their excellent infrared transmittance and low temperature coefficient of refractive index, are widely used in infrared optical systems, laser windows, and precision imaging devices. To improve the environmental resistance of chalcogenide glasses, functional coatings such as sulfides, selenides, or tellurides are typically deposited on the glass surface. The mechanical strength of the coating—especially its abrasion resistance—directly determines the lifespan and optical stability of the components; therefore, strength testing of the chalcogenide glass coating before shipment is a necessary procedure.

[0003] Currently, the industry commonly uses handheld abrasion testers to manually polish and test the film layer: the operator holds the chalcogenide glass with one hand and firmly holds the abrasion tester with the other hand. After polishing the film layer a specified number of times under the set pressure, the operator observes the film layer with the naked eye or a microscope to see if there are scratches, peeling, or wear. However, the uneven positioning and force applied by the operator result in large differences in polishing pressure, angle, and speed for the same batch of samples, leading to poor repeatability of the test results. Utility Model Content

[0004] The purpose of this invention is to provide a chalcogenide glass film strength testing device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a chalcogenide glass film strength testing device, comprising:

[0006] Testing base;

[0008] A lifting drive cylinder is installed on the support column, and its piston rod is connected to a lifting crossbeam that can slide up and down.

[0009] A grinding motor is fixed to the upper surface of the lifting beam, and its output end drives at least one film grinding wheel.

[0010] A glass support stage is disposed on the detection base and used to position and place chalcogenide glass.

[0011] The lifting drive cylinder drives the lifting beam to descend so that the film grinding wheel contacts the chalcogenide glass film. The grinding motor drives the film grinding wheel to rotate, thereby automatically grinding the film and realizing the detection of film strength.

[0012] Preferably, the supporting column is provided with a guide rail extending in the vertical direction, and the lifting beam is provided with a guide slider that slides with the guide rail to guide the vertical movement of the lifting beam in a straight line.

[0013] Preferably, the output end of the grinding motor is coaxially fixed with a drive pulley, which drives two driven pulleys simultaneously through a synchronous belt. Each driven pulley is connected to a grinding shaft that passes downward through the lifting beam, and a film grinding wheel is fixed at the lower end of each grinding shaft.

[0014] Preferably, the glass support stage includes a rotary drive motor disposed within the detection base and a rotary shaft driven by the rotary drive motor and protruding from the upper surface of the detection base.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0025] refer to Figure 1 , Figure 2 and Figure 3 As shown, the system includes a testing base 1; a support column 2 fixed to the testing base 1; a lifting drive cylinder 3 installed on the support column 2, with its piston rod connected to a lifting beam 4 that can slide up and down; a grinding motor 5 fixed to the upper surface of the lifting beam 4, with its output end driving at least one film grinding wheel 6; and a glass support platform 7 disposed on the testing base 1 and used for positioning and placing chalcogenide glass. The lifting drive cylinder 3 drives the lifting beam 4 to descend so that the film grinding wheel 6 contacts the chalcogenide glass film, and the grinding motor 5 drives the film grinding wheel 6 to rotate, thereby automatically grinding the film and realizing the detection of film strength. The automatic grinding structure, consisting of lifting drive cylinder 3, grinding motor 5, and film grinding wheel 6, eliminates the need for manual hand-held operation. The lifting drive cylinder 3 can complete the grinding positioning in one descent. The stroke and air supply pressure of the lifting drive cylinder 3 are adjustable to ensure a constant positive pressure between the film grinding wheel 6 and the chalcogenide glass. The structure of active pulley-synchronous belt 11-double driven pulley 12 enables the two film grinding wheels 6 to rotate synchronously. Two wear data points can be obtained in one clamping, which is convenient for statistical evaluation of film uniformity.

[0026] refer to Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the supporting column 2 is equipped with a guide rail 8 extending vertically, and the lifting beam 4 is equipped with a guide slider 9 that slides with the guide rail 8 to linearly guide the up and down movement of the lifting beam 4, forming a guide rail 8-guide slider 9 kinematic pair to ensure that the descent path of the film grinding wheel 6 is consistent each time. The output end of the grinding motor 5 is coaxially fixed with a drive pulley, which drives two driven pulleys 12 simultaneously through a synchronous belt 11. Tensioning pulleys 10 are provided between the two driven pulleys 12 and the drive pulley, thereby increasing the tension of the synchronous belt 11 and improving its synchronization effect. Each driven pulley 12 is connected to a grinding shaft 13 that passes downward through the lifting beam 4. A film grinding wheel 6 is fixed at the lower end of each grinding shaft 13. Two wear data points are obtained in one press, doubling the sample size. The linear velocities of the two film grinding wheels 6 are strictly equal, eliminating the error caused by sequential grinding. Compared with using two motors, a servo system is saved, reducing costs. The glass support stage 7 includes a rotary drive motor disposed within the testing base 1 and a rotary shaft 15 driven by the rotary drive motor and protruding from the upper surface of the testing base 1. The rotary shaft 15 is connected to the lower surface of the glass support stage 7, concealing the rotary drive motor inside the testing base 1, preventing dust from easily entering and reducing the failure rate. Grooves 16 are provided on both sides of the upper surface of the glass support stage 7, facilitating the removal of chalcogenide glass from the glass support stage 7 by operators.

[0027] The lifting drive cylinder 3 is mounted on the support column 2 via the fixing plate 14, which improves the stability of the lifting drive cylinder 3 during operation.

[0028] In use, first, wearing clean gloves, place the chalcogenide glass to be tested flat in the center of the glass support platform 7. The lifting drive cylinder 3 drives the lifting beam 4 to descend, allowing the film grinding wheel 6 to contact the glass surface. The grinding motor 5 starts, driving the drive pulley to rotate. Under the synchronization of the synchronous belt 11, it drives the two driven pulleys 12 to rotate, which in turn drives the grinding shaft 13 to rotate the film grinding wheel 6, thereby grinding the film on the glass surface. The staff can record the grinding state of the film at the same time to complete the strength test.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
