[0002] A thermometer is a tool that can accurately determine and measure temperature. They are divided into pointer thermometers and digital thermometers. Various types of thermometers have been designed and manufactured to suit different purposes.

[0003] In the manufacturing process of glass thermometers, it is necessary to scribing the surface of the thermometer. During the scribing process, the high and low temperature positions of the thermometer need to be scribed separately. Existing scribing equipment usually requires manual observation and scribing, which is not only time-consuming and labor-intensive, but also prone to inaccurate scribing positions. Therefore, we propose an automatic scribing device for glass thermometers. Summary of the Invention

[0027] Preferably, the acquisition device 5 consists of a fifth mounting frame 30, a sixth mounting frame 31, an industrial camera 32, a support rod 33, and a searchlight 34. The fifth mounting frame 30 is fixedly connected to the top of the support frame 1 and to one side of the connecting chain 15. The sixth mounting frame 31 is fixedly connected to one side of the fifth mounting frame 30. The industrial camera 32 is fixedly connected to the surface of the sixth mounting frame 31. The industrial camera 32 is used to acquire the marked position on the thermometer surface. The support rod 33 is fixedly connected to the top of the support frame 1 and between the two sets of connecting chains 15. The searchlight 34, which illuminates the thermometer, is fixedly connected to the top of the support rod 33 and to the position corresponding to the industrial camera 32. The acquisition device 5 is designed to be transparent under the illumination of the searchlight 34, thereby marking the position of the liquid column at a certain temperature. Data is transmitted through the industrial camera 32, and the electric slide 36 and electric slider 37 of the marking mechanism 6 are controlled to operate, thus facilitating the marking of the liquid column position on the thermometer.

[0028] Preferably, the marking mechanism 6 consists of a seventh mounting frame 35, an electric slide block 36, an electric slider 37, and a marking machine 38. The top of the support frame 1 and both sides corresponding to the connecting chain 15 are fixedly connected to the seventh mounting frame 35.

[0029] In use, firstly, the thermometer to be processed is placed inside the support groove 17. Then, the dual-axis motor 10 is started. The operation of the dual-axis motor 10 drives the first gear disk 11 and the connecting chain 15 at its output end to move along the outer surface of the second gear disk 14. The elliptical support groove 17 supports the thermometer, ensuring that the thermometer does not fall off the surface of the support plate 16 during transport. Subsequently, when the dual-axis motor 10 rotates, it drives the first transmission wheel 26 and the flat plate 25 to rotate along the inside of the second fixed bearing 23 through the second transmission wheel 28 and the conveyor belt 29. The inclined surface of the flat plate 27 can level the thermometer in the left and right directions during transport. This setting not only prevents the thermometer from being leveled but also prevents the use of electric telescopic mechanisms. When the thermometer passes the bottom of the leveling pad 21, the electric telescopic rod 19 is activated. The operation of the electric telescopic rod 19 can drive the connecting frame 20 and the leveling pad 21 to move downwards. This allows the leveling pad 21, made of rubber material, to level the conveyed thermometer, preventing it from tilting inside the carrying tank 17. Subsequently, the conveying device will move the leveled thermometer to the bottom of the industrial camera 32. Under the illumination of the searchlight 34, the thermometer becomes transparent, allowing the position of the liquid column at a certain temperature to be marked. Data is transmitted through the industrial camera 32, which controls the operation of the electric slide 36 and electric slider 37 of the marking mechanism 6, facilitating the marking of the liquid column position of the thermometer.
