Description

Technical Field

[0001] The utility model relates to the field of PCB production, in particular to an anti-damage temperature sensor used in PCB production. Background Art

[0002] In the process of PCB production, it is often necessary to heat the medicine to improve the effect of the medicine and improve the production quality of the product. In the production process, a temperature sensor is usually suspended by a rope and inserted into the tank to detect and monitor the temperature of the medicine. The traditional temperature checker is a mercury glass thermometer. The defect of this thermometer is that it is fragile and easily damaged after a slight collision. The mercury in the thermometer melts into the medicine tank and contaminates the medicine, causing abnormal production quality. Utility Model Content

[0003] In order to solve the above problems, the present technical solution provides an anti-damage temperature sensor for PCB production.

[0004] To achieve the above purpose, the technical solution is as follows:

[0005] A damage-proof temperature sensor for PCB production comprises a steel sleeve, wherein an inner cavity is provided in the middle of the steel sleeve, the bottom of the inner cavity is fixedly connected to a glass thermometer, a temperature sensing head of the glass thermometer extends out of the inner cavity, and a steel cover is extended from the temperature sensing head of the glass thermometer to the steel sleeve.

[0006] In some embodiments, the bottom of the glass thermometer is fixed by acid and alkali resistant glue.

[0007] In some embodiments, the steel sleeve is provided with a steel ring.

[0008] In some embodiments, a connecting portion is provided on the outer circumference of the steel sleeve, an anti-collision outer ring is provided on the connecting portion, and a plurality of elastic portions are provided on the circumference of the anti-collision outer ring.

[0009] In some embodiments, the elastic portion includes a sliding portion slidably disposed on the anti-collision outer ring, and a spring having one end connected to the sliding portion and the other end connected to the anti-collision outer ring.

[0010] The beneficial effects of this application are:

[0011] This application is protected by a stainless steel sleeve, and the glass temperature sensor is fixed in the stainless steel sleeve to prevent the glass temperature sensor from touching the cylinder body and causing damage. In addition, the part of the temperature sensor extending out of the inner cavity is surrounded by a steel cover, which not only does not affect normal detection, but also can further protect the temperature sensor from contacting the cylinder body. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] In order to more clearly illustrate the technical solutions in the embodiments of the present utility model, the following briefly introduces the drawings required for describing the embodiments.

[0015] In order to make the technical problems, technical solutions and beneficial effects solved by the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0016] Please refer to Figure 1-2 As shown, an anti-damage temperature sensor for PCB production includes a steel sleeve 1, an inner cavity is provided in the middle of the steel sleeve 1, the bottom of the inner cavity is fixedly connected to a glass thermometer 2, the temperature sensing head of the glass thermometer 2 extends out of the inner cavity, and a steel cover 3 is extended from the steel sleeve 1 at the temperature sensing head of the glass thermometer 2.

[0017] This application is protected by a stainless steel sleeve, and the glass temperature sensor is fixed in the stainless steel sleeve to prevent the glass temperature sensor from touching the cylinder body and causing damage. In addition, the part of the temperature sensor extending out of the inner cavity is surrounded by a steel cover, which not only does not affect normal detection, but also can further protect the temperature sensor from contacting the cylinder body.

[0018] In this embodiment, the bottom of the glass thermometer 2 is fixed by acid- and alkali-resistant glue.

[0019] In this embodiment, the steel sleeve 1 is provided with a steel ring 4 for connecting a rope to suspend the sensor.

[0020] In this embodiment, a connecting portion 5 is provided on the outer periphery of the steel sleeve 1, an anti-collision outer ring 6 is provided on the connecting portion 5, and a plurality of elastic portions 7 are provided circumferentially on the anti-collision outer ring 6, and the elastic portion 7 includes a sliding portion 71 slidably arranged on the anti-collision outer ring 6, and a spring 72 connected to the sliding portion 71 at one end and to the anti-collision outer ring 6 at the other end. The present application adopts 360-degree protection. When the temperature sensor touches the inner wall of the cylinder body, the sliding portion collides with the inner wall. At this time, the spring is compressed and absorbs a large part of the force, and then releases to allow the temperature sensor to bounce off, thereby leaving the inner wall, which not only plays a role in anti-collision buffering, but also can leave the inner wall.

[0021] The above description is only a preferred embodiment of the present application and is not intended to limit the scope of implementation of the present application. Other principles and basic structures that are the same or similar to those of the present application are within the protection scope of the present application.
