[0002] Optical glass is a kind of inorganic amorphous material specially designed and prepared with high precision, which has excellent optical performance and is optimized for controlling the behavior of light propagation (such as refraction, reflection and dispersion). The impact test of optical glass is a key test for evaluating its anti-cracking performance, energy absorption capacity and structural integrity under dynamic load, and the test method mostly adopts the drop ball impact test.

[0003] The Chinese invention patent with the publication number CN117147343B discloses a high-strength tempered glass impact test device, which comprises a receiving platform and an impact device; a displacement device is arranged above the receiving platform; a mounting frame is fixedly arranged on the displacement device; a first gear is arranged in the mounting frame, and the lower side of the first gear is not provided with meshing teeth; a plurality of second gears are uniformly arranged around the first gear along the axis of the first gear, and the first gear and the second gears are meshed with each other; a driving device is arranged on the mounting frame; a winding shell is arranged around the second gears, and the winding shell moves synchronously with the second gears; a release opening is formed in the side wall of the winding shell; a rope is wound on the rotating shaft; a small ball is fixedly arranged at the end of the rope; and an induction device is arranged on one side of the first gear. The device can automatically recover after releasing the small ball, without the need to replace the small ball, thereby reducing the workload and avoiding the influence of the test results when the small ball cannot be recovered after being released.

DETAILED DESCRIPTION

[0042] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by a person of ordinary skill in the art without creative effort belong to the scope of protection of the present application.

[0043] As shown in Figures 1 to 9 The present application provides an impact test device for optical glass manufacturing, comprising a receiving platform 1, further comprising:

[0044] A guide assembly 2 is installed on the receiving platform 1:

[0045] A support assembly 5 is arranged on the guide assembly 2;

[0046] A protection assembly 4 is installed on the support assembly 5;

[0047] A reset assembly 3 is arranged on the guide assembly 2;

[0048] The support assembly 5 comprises a first support frame 51 sliding on the guide assembly 2, a movable frame 52 movably arranged inside the first support frame 51, a support roller 55 movably installed at one end of the movable frame 52, guide grooves 59 formed on both sides of the first support frame 51, and connecting pieces 54 sliding in the guide grooves 59 and fixed at both ends of the movable frame 52;

[0049] A connecting plate 57 is fixed to the side of the first support frame 51, and a second tension spring 58 for pulling the connecting piece 54 is arranged on the connecting plate 57;

[0050] The support assembly 5 is symmetrically arranged on both sides of the guide assembly 2;

[0051] The guide assembly 2 comprises a magnetic attraction device 21 fixed to the receiving platform 1, a steel ball 24 attracted to the bottom of the magnetic attraction device 21, a guide cover 22 fixed to the outside of the magnetic attraction device 21, a protection baffle 25 fixed to the bottom of the guide cover 22, and a rectangular through slot 23 formed in the middle of the guide cover 22;

[0052] A vertical slot for vertical sliding of the first support frame 51 is formed in the side of the guide cover 22, and the support roller 55 is located inside the guide cover 22;

[0053] A cylinder for driving the first support frame 51 to move along the vertical slot is fixed to the side of the guide cover 22;

[0054] The initial state of the movable frame 52 is located at the upper end of the guide groove 59 through the connecting piece 54. During the downward movement of the steel ball 24, the support roller 55 pushes the movable frame 52 to move along the guide groove 59, and under the action of the second tension spring 58, the movable frame 52 is located at the lower end of the guide groove 59, thereby shortening the distance between the two support rollers 55.

[0055] By placing the optical glass on the receiving platform 1, the steel ball 24 is vertically dropped and hits the optical glass under the action of the magnetic attraction device 21. During the falling process, the two support assemblies 5 are pushed to move in opposite directions, so that the movable frame 52 moves along the guide groove 59 to the vertical end through the connecting piece 54. At this time, the movable frame 52 and the support roller 55 move in the opposite direction along the lower end of the guide groove 59 under the action of the second tension spring 58, thereby reducing the distance between the two support rollers 55. During the rebounding process of the steel ball 24, the two support rollers 55 move downward and shorten the distance between them. The two support rollers 55 support the steel ball 24, avoiding the steel ball 24 from hitting the optical glass twice, thereby ensuring the accuracy of the impact test of the optical glass.

[0056] The connection between the magnetic attraction device 21 and the receiving platform 1 is not deviated from the application, and a guide rail mechanism is added to enable the guide assembly 2 to move horizontally, vertically and upward and downward on the receiving platform 1, thereby realizing multi-point testing and testing at different heights of the optical glass.

[0057] As shown in Figure 3 As shown in Figure 9 The support assembly 5 further includes a protective cover 53 fixed to the movable frame 52. The protective cover 53 is connected to the first support frame 51 through the rubber connecting piece 56. The first support frame 51 is externally provided with a rubber sealing gasket 50 for sealing the guide groove 59.

[0058] The protective assembly 4 includes an annular tube 41 fixed to the outside of the first support frame 51. The annular tube 41 is connected to a gas injection device. The bottom of the annular tube 41 is provided with a gas injection hole.

[0059] The bottom of the annular tube 41 is fixed with a first guide plate 42 and a second guide plate 43. The first guide plate 42 and the second guide plate 43 form a converging flow channel. The gas injection hole is located in the converging flow channel. The gap between the first guide plate 42 and the second guide plate 43 gradually decreases from top to bottom.

[0060] When the first support frame 51 is located at the lower end of the vertical groove of the guide cover 22, the first guide plate 42 is overlapped on the top of the protective baffle 25.

[0061] The steel ball 24 falls to impact the optical glass, and the protective baffle 25 protects the splashed debris generated by the impact, and the first guide plate 42 and the second guide plate 43 gather the airflow to form an air curtain, so as to avoid the splashing of the debris, thereby improving the safety of the optical glass impact test.

[0062] The middle part of the receiving platform 1 is in a mesh structure, and the optical glass is located at the top of the mesh structure. During the process of gathering the air curtain to inject gas into the middle part, the gas is discharged through the mesh structure, so as to avoid the airflow from being discharged from all around and carrying the optical glass debris.

[0063] As shown in Figure 3 , Figure 7 and Figure 9 , one end of the first support frame 51 is fixed with the second support frame 511, and the second support frame 511 is in communication with the annular pipe 41.

[0064] The second support frame 511 movably has the movable rod 516, the second support frame 511 is provided with the gas inlet hole 513, and the movable rod 516 is provided with the communication hole 514.

[0065] The two ends of the movable frame 52 are fixed with the transmission teeth 512, and the two ends of the movable rod 516 are fixed with the sector gear 515.

[0066] When the movable frame 52 is located at the upper end of the first support frame 51, the communication hole 514 does not coincide with the gas inlet hole 513.

[0067] When the movable frame 52 moves along the guide groove 59 through the connecting piece 54, the transmission teeth 512 are engaged with the sector gear 515, and the movable rod 516 is driven to rotate, so that the gas inlet hole 513 is communicated with the annular pipe 41 through the communication hole 514.

[0068] The movable frame 52 and the connecting piece 54 are driven to move along the guide groove 59 to the vertical end of the guide groove 59 by the steel ball 24 falling, so that the transmission teeth 512 are engaged with the sector gear 515. During the downward movement of the movable frame 52, the sector gear 515 and the movable rod 516 are driven to rotate by the transmission teeth 512, so that the annular pipe 41 is communicated with the first support frame 51, the gas in the annular pipe 41 enters the first support frame 51 to drive the movable frame 52 and the support roller 55 to move reversely along the lower end of the guide groove 59, thereby improving the speed of the support roller 55, and increasing the stability of the support roller 55 supporting the steel ball 24.

[0069] As shown in Figure 7 and Figure 8As shown, the reset assembly 3 comprises a guide frame 31 fixed to the outside of the guide cover 22, the top of the guide frame 31 is hinged with a guide rod 34, the guide frame 31 is provided with a first tension spring 33 for pulling the guide rod 34, and the side of the guide frame 31 is provided with a damping pad 32.

[0070] After the impact of the steel ball 24 on the optical glass is completed, the support roller 55 supports the steel ball 24 to avoid secondary impact on the optical glass, at this time, the cylinder drives the support assembly 5 and the steel ball 24 to move upwards along the guide cover 22, and the steel ball 24 is adsorbed by the magnetic attraction device 21 during the upward movement;

[0071] Meanwhile, the connecting piece 54 pushes the guide rod 34 to rotate during the upward movement, and is located at the top of the guide rod 34, and then the first support frame 51 is pushed downward by the cylinder to move downward, the connecting piece 54 is guided by the guide rod 34 to move along the guide groove 59 to the vertical end, at this time, the connecting piece 54 is in contact with the damping pad 32 and moves downward, and under the action of the friction force of the damping pad 32, the connecting piece 54 moves upward along the vertical end of the guide groove 59, and is guided by the guide groove 59 to reset at the upper end of the guide groove 59, that is, it can be recycled.

[0072] The working principle and use process of the application are as follows:

[0073] By placing the optical glass on the receiving platform 1, the steel ball 24 is adsorbed by the magnetic attraction device 21 and vertically falls to impact the optical glass, and in the process of falling, the two support assemblies 5 move in opposite directions, so that the movable frame 52 moves along the guide groove 59 to the vertical end through the connecting piece 54, at this time, the movable frame 52 and the support roller 55 move in the opposite direction along the lower end of the guide groove 59 under the action of the second tension spring 58, thereby reducing the distance between the two support rollers 55, and in the process of rebounding of the steel ball 24, the two support rollers 55 move downward and shorten the distance between them, and the steel ball 24 is supported by the two support rollers 55 to avoid secondary impact on the optical glass;

[0074] When the steel ball 24 falls to impact the optical glass, the protective baffle 25 is used to protect the debris splashed by the impact, and the airflow is gathered to form an air curtain by the first guide plate 42 and the second guide plate 43, so as to avoid the splashing of debris;

[0075] When the steel ball 24 falls and pushes the movable frame 52 and the connecting piece 54 to move along the guide groove 59 to the vertical end of the guide groove 59, the transmission tooth 512 is engaged with the sector gear 515, and when the movable frame 52 moves downward, the sector gear 515 is driven to rotate by the transmission tooth 512 and the movable rod 516, so that the annular tube 41 is communicated with the first support frame 51, and the gas in the annular tube 41 enters the first support frame 51 to push the movable frame 52 and the support roller 55 to move reversely along the lower end of the guide groove 59, thereby increasing the speed of the support roller 55 and increasing the stability of the support roller 55 to the steel ball 24;

[0076] After the steel ball 24 impacts the optical glass, the support roller 55 supports the steel ball 24 to avoid secondary impact on the optical glass, and at this time, the cylinder drives the support assembly 5 and the steel ball 24 to move upward along the guide cover 22, and the steel ball 24 is adsorbed by the magnetic attraction device 21 during the upward movement;

[0077] Meanwhile, the connecting piece 54 pushes the guide rod 34 to rotate during the upward movement, and is located at the top of the guide rod 34, and then the first support frame 51 is pushed downward by the cylinder to move downward, and the connecting piece 54 is guided by the guide rod 34 to move along the guide groove 59 to the vertical end, at this time, the connecting piece 54 contacts the damping pad 32 and moves downward, and under the action of the friction force of the damping pad 32, the connecting piece 54 moves upward along the vertical end of the guide groove 59, and is reset at the upper end of the guide groove 59 under the guidance of the guide groove 59, that is, it can be recycled.
