[0001] This application belongs to the technical field of glass testing equipment manufacturing, and specifically relates to a laser emitter with adjustable laser emission angle. Background Art

[0002] In many fields such as modern industrial production, scientific research experiments, and quality inspection, laser technology has been extremely widely used due to its unique advantages such as high energy density, high directivity, and high monochromaticity. Taking the glass processing and testing industries as an example, the performance and functions of laser emitters directly affect production efficiency and product quality.

[0003] During the glass manufacturing process, in order to ensure that the quality of glass products meets the standards, it is necessary to detect the glass. By emitting laser beams at different angles through a laser emitter to irradiate the glass, detection data can be obtained, and then whether there are defects inside the glass can be analyzed.

[0004] However, when existing laser emitters are applied to glass detection, many laser emitters are usually fixedly installed on detection equipment, which makes their emission angles manually adjusted by quality inspectors, with poor accuracy, resulting in a reduction in the accuracy of detection. Summary of the Invention

By using a slider driven by a servo motor on an arc track to set the laser emitter body, a laser emitter with adjustable laser emission angle is designed.

[0025] As Figures 1-4 shown, a laser emitter with adjustable laser emission angle includes a base 1. An arc track 24 and a laser emitter body 21 are provided on the base 1. The arc of the arc track 24 is located on a virtual circle. A slider 25 is slidably provided between the two ends of the arc track 24. The laser emitter body 21 is arranged on the slider 25. The light ray emitted by the laser emitter body 21 faces the center of the virtual circle. A servo motor 31 is provided on the slider 25. A gear 32 is coaxially and fixedly provided on the output shaft of the servo motor 31. An arc rack 33 meshing with the gear 32 is coaxially provided on the convex surface of the arc track 24.

[0026] In this embodiment, an arc track 24 and a laser emitter body 21 are provided on the base 1. The base 1 arranges the arc track 24 through a fixed block 22. Support legs 23 are provided at the bottom end of the arc track 24 to support the arc track 24. The glass 5 to be detected is placed on the base 1. A light receiving sensor for receiving the light irradiated by the laser emitter body 21 is placed at the center of the virtual circle to receive and read the light ray that penetrates the glass 5 by the laser emitter body 21. The servo motor 31 is driven to drive the gear 32, and then drive the laser emitter body 21 to slide on the arc track 24, so as to realize the angle adjustment.

[0027] As a preferred embodiment, the arc-shaped rack 33 is attached to the outer wall of the arc-shaped track 24, which facilitates the replacement of the arc-shaped rack 33.

[0028] As a preferred embodiment, a clamping assembly is provided on the upper surface of the base 1, and the clamping assembly is located on the concave side of the arc-shaped track 24. After such a setting, the glass to be detected is clamped by the clamping assembly. Since the light emitted by the laser emitter body 21 is directed towards the center of the virtual circle, the clamping assembly needs to be arranged on the concave side of the arc-shaped track 24.

[0029] As a preferred embodiment, the clamping assembly includes a first clamping plate 41 and a second clamping plate 43 that cooperate with each other. The first clamping plate 41 and the second clamping plate 43 are parallel to each other. The first clamping plate 41 is perpendicular to the plane of the arc of the arc-shaped track 24. The second clamping plate 43 is fixedly arranged on the base 1. The first clamping plate 41 is slidably arranged on the base 1. The sliding direction of the first clamping plate 41 is perpendicular to the second clamping plate 43. The first clamping plate (41) and the second clamping plate (42) are arranged at intervals and the distance therebetween is adjustable. A threaded rod 411 penetrates through the first clamping plate 41. A rubber pad 42 is rotatably connected to one end of the threaded rod 411 facing the second clamping plate 43. The second clamping plate 43 is fixed on the base 1. After such a setting, the glass 5 to be detected is clamped by the first clamping plate 41 and the second clamping plate 43. The purpose of the threaded rod 411 driving the rubber pad 42 is to prevent the first clamping plate 41 from directly contacting the glass 5 and causing damage to the glass 5. Another function of the threaded rod 411 is to play a fine-tuning role, that is, first move the first clamping plate 41 towards the second clamping plate 43 to initially clamp the glass 5, and then perform fine-tuning through the threaded rod 411 to ensure that the glass 5 is not damaged when it is clamped.

[0030] As a preferred embodiment, a locking mechanism is provided on the base 1, and the locking mechanism is used to lock the relative distance between the first clamping plate 41 and the second clamping plate 43.

[0031] As a preferred embodiment, the execution end of the locking mechanism is controllably connected to the first clamping plate 41. Through the setting of the locking mechanism, after the first clamping plate 41 and the second clamping plate 43 clamp the glass 5, the first clamping plate 41 is fixed.

[0032] As a preferred embodiment, the locking mechanisms are provided on both sides of the base 1, and the connecting rod 412 is horizontally arranged on the base 1 and connects the two locking mechanisms.

[0033] As a preferred embodiment, the locking mechanism includes a guide rod 44, a connecting rod 412, a ratchet wheel 46, and a pawl 48. The guide rod 44 is disposed on a side wall of the first clamping plate 41 parallel to the sliding direction of the first clamping plate 41 on the base 1. The connecting rod 412 is rotatably provided on the base 1. The ratchet wheel 46 is coaxially and fixedly provided on the connecting rod 412. The connecting rod 412 is parallel to the guide rod 44. An actuating rod 45 is radially provided on the connecting rod 412. A chute is provided on the actuating rod 45. The length line of the chute is parallel to the actuating rod 45. One end of the guide rod 44 facing away from the first clamping plate 41 is slidably connected between the two ends of the chute. A rotating rod is fixedly provided on the base 1. The pawl 48 is rotatably provided on the rotating rod coaxially. The pawl 48 and the rotating rod are fixedly connected by a torsion spring 410. After such a setting, during the process of the first clamping plate 41 approaching and clamping the glass 5 towards the second clamping plate 43, the actuating rod 45 is driven to rotate. When the actuating rod 45 rotates, the ratchet wheel 46 is driven to rotate, and the pawl 48 then catches the ratchet wheel 46 to prevent the ratchet wheel 46 from rotating back. The actuating rod 45 has the function of blocking the guide rod 44, thereby restricting the first clamping plate 41 and preventing the first clamping plate 41 from moving towards the second clamping plate 43. When the glass 5 has been detected and needs to be removed, by lifting the pawl 48 by hand to make the pawl 48 leave the ratchet wheel 46, the limit on the first clamping plate 41 can be released.

[0034] As a preferred embodiment, a turntable 47 is coaxially and fixedly provided at one end of the connecting rod 412 facing away from the base (1). A handle is provided on the turntable 47. In this way, by holding the handle and rotating the turntable 47, the first clamping plate 41 can be manually controlled to move towards or away from the second clamping plate 43 in a labor-saving manner (because the handle is eccentrically provided on the turntable 47).

[0035] As a preferred embodiment, a coaxial fixing sleeve 49 is fixedly provided at one end of the rotating rod facing away from the base 1. The torsion spring 410 is coaxially arranged inside the fixing sleeve 49. One torsion arm of the torsion spring 410 is fixedly connected to the fixing sleeve 49, and the other torsion arm is fixedly connected to the pawl 48. Since the torsion spring 410 is relatively easy to break and belongs to a consumable part, it is more convenient to replace the torsion spring 410 by arranging the torsion spring 410 through the fixing sleeve 49.
