Description

Technical Field

[0001] This application relates to the field of glass lens impact testing machine technology, and in particular to a fully automatic steel ball impact testing device. Background Technology

[0002] With the rapid development of the packaging industry, flexible packaging materials such as plastic films and sheets are being used more and more widely, and their related properties are gradually receiving more attention. Among these, the drop impact resistance of films and sheets is one of their important mechanical strength indicators. Steel ball impact testing is mainly used for testing the impact resistance of products such as plastics, building materials, ceramics, acrylic, glass, coatings, and hardware. The test measures the degree of material damage and the impact energy. This instrument can also be used to conduct comparative impact tests on samples of the same material and specifications to assess the quality of the materials.

[0003] In the production of eyeglass lenses, to test their impact resistance and drop resistance, samples need to be subjected to steel ball impact tests to determine if they meet standards. However, current lens impact tests often require two testers working together: one stands to manually open the steel ball clamp, while the other squats at the bottom of the equipment to retrieve the tested steel ball and hand it to the standing person. This process is time-consuming, labor-intensive, and highly inefficient. Furthermore, the steel ball bounces after hitting the glass, potentially propelling it outside the testing equipment, posing a safety hazard. The tested stainless steel ball also needs to be manually collected and re-secured, which is extremely inconvenient.

[0004] Therefore, there is an urgent need for a more automated, more efficient, and safer testing device. Utility Model Content

[0030] The inventors discovered through analysis of existing technologies that existing steel ball impact testing devices require human intervention to complete the test, the steel ball is likely to hit the staff after it falls, the height of the falling steel ball cannot be adjusted, and the overall testing process is not intelligent or automated.

[0031] Reference Figure 1-3 This diagram illustrates a fully automatic steel ball impact testing device provided in this application. The device includes a test base 1, a transmission guide 2, a test guide 3, and a cylindrical guide tube 4. A transmission chain 21 (not shown in the diagram as it is installed on the inner wall of the transmission guide 2) is mounted on the inner wall of the transmission guide 2. The test base 1 has a steel ball slide 12. The transmission guide 2 is vertically fixed to the top surface of the test base 1. The cylindrical guide tube 4 is adjustablely connected to the transmission guide 2 and is parallel to the transmission guide 2. One end of the test guide 3 is fixed to the top of the transmission guide 2, and the other end has a through hole 321 opposite to the top opening of the cylindrical guide tube 4. The angle between the test guide 3 and the transmission guide 2 is less than 90°. After the impact test, the falling steel ball rolls through the steel ball slide 12 into the third guide 33 and is then transported back to the test guide 3 by the transmission chain 21.

[0032] In the embodiments of this application, the fully automatic steel ball impact testing device specifically includes a test base 1, a transmission guide 2, a test guide 3, and a cylindrical guide tube 4; wherein, a transmission chain 21 is installed on the inner wall of the transmission guide 2, and the test base 1 is provided with a steel ball slide 12; the transmission guide 2 is vertically fixed to the top surface of the test base 1; the cylindrical guide tube 4 is adjustablely connected to the transmission guide 2, and the cylindrical guide tube 4 is parallel to the transmission guide 2; one end of the test guide 3 is fixed to the top of the transmission guide 2, and the other end is provided with a through hole 321 opposite to the top opening of the cylindrical guide tube 4; wherein, the included angle between the test guide 3 and the transmission guide 2 is less than 90°; after the impact test, the falling steel ball rolls down through the steel ball slide 12 into the first guide 31, and is transmitted back to the test guide 3 by the transmission chain 21. The aforementioned fully automatic lens drop ball impact testing device utilizes the steel ball slide 12 and transmission guide 2 during the testing process, eliminating repetitive manual assistance actions by the testing personnel, saving labor, enhancing the continuity of the test, and improving the efficiency of the test. By controlling the switch and the cylindrical guide tube 4 to drop the steel ball, the safety of the test is improved, and the drop height of the steel ball is also adjustable, not fixed. The controller and operation panel 8 can realize the statistics of the number of tests and the drop height, as well as the visualization of the operation process, making the test more intelligent.

[0033] The fully automatic steel ball impact testing device of this exemplary embodiment will now be further described.

[0034] In one embodiment of this application, the test guide groove 3 includes a first guide groove 31 and a second guide groove 32; one end of the first guide groove 31 is fixedly connected to the top end of the transmission guide groove 2, and the other end is fixedly connected to the second guide groove 32; wherein, the groove extension direction of the first guide groove 31 is perpendicular to the groove extension direction of the second guide groove 32; a control switch is provided at the end of the first guide groove 31 away from the transmission guide groove 2 to control whether the steel ball is subjected to drop impact. The control switch includes an electromagnet 5, a cylinder 6, and a toggle switch 7. The cylinder 6 and the toggle switch 7 are connected. The electromagnet 5 is connected to a power source. When the electromagnet 5 is de-energized, the toggle switch 7 is opened, and the steel ball rolls into the through hole 321. The through hole 321 is provided at the end of the second guide groove 32 away from the first guide groove 31, and the through hole 321 is opposite to the opening at the top end of the cylindrical guide tube 4. The test base 1 is provided with a third guide groove 33. One end of the third guide groove 33 is connected to the steel ball slide, and the other end is connected to the groove at the bottom of the transmission guide groove 2.

[0035] It should be noted that the steel ball is transported through the transmission guide 2 to the inlet of the first guide 31 of the test guide 3. Due to the weight of the steel ball itself and the design that the angle between the first guide 31 and the transmission guide 2 is less than 90 degrees, the steel ball rolls to the electromagnet 5 at the end of the first guide 31 away from the transmission guide 2. At this time, the electromagnet 5 is energized, and the steel ball is attracted to the electromagnet 5, preventing it from falling. When the controller receives the start test command, the electromagnet 5 is de-energized from the external power supply, and the steel ball is no longer attracted to the electromagnet 5. At this time, the locking tongue of the electromagnet 5 retracts, and the toggle switch 7 is opened under the action of the cylinder 6. The steel ball rolls into the inclined second guide 32 and falls into the through hole 321, passing through the through hole 321 and entering the cylindrical guide tube 4 for impact testing.

[0036] It should be noted that after each impact, the steel ball can enter the test guide 3 through the transmission guide 2 and be in a state of waiting for testing.

[0037] In one embodiment of this application, the steel ball slide is arranged in a sloping manner on the test base 1. The top surface of the test base 1 is provided with an impact seat 9, and the top surface of the impact seat 9 is provided with an impact metal part 10, which is opposite to the opening at the bottom end of the cylindrical guide tube 4.

[0038] It should be noted that the width, length, and number of turns of the steel ball track are not limited here, and can be designed according to the size of the test base 1. The impact seat 9 is designed with a certain tilt angle to facilitate the steel ball to automatically roll into the third guide groove 33 after impacting the sample, thereby allowing the steel ball to roll into the slot at the bottom of the transmission guide groove 2.

[0039] It should be noted that the cylindrical guide tube 4 has several tiny perforations to reduce air resistance when the steel ball falls.

[0040] It should be noted that the height of the cylindrical conduit 4 is adjustable to suit the requirements of products of different specifications. The cylindrical conduit 4 is adjustable to the transmission guide groove 2, for example, by means of a combination of fixing parts and screws, or by means of a vertical slide rail. Specific implementation methods are not limited.

[0041] In one embodiment of this application, the test base 1 is surrounded by a fence 11. An operation panel 8 is embedded in the test base 1, and a motor and a controller are disposed within the test base 1. The motor is electrically connected to the controller. The operation panel 8 is electrically connected to the controller and includes functions such as drop test initiation, drop count recording, running status indication, ball transport status display, and alarm functions. An emergency stop button is also provided on the operation panel 8.

[0042] It should be noted that the test base 1 is surrounded by a fence 11 of a preset height to prevent the impacting steel ball from popping out and injuring people. The fence 11 can be made of impact-resistant glass, and its implementation is not limited.
