[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the following embodiments are only some specific implementation methods of the utility model, but not all embodiments. The following exemplary embodiment description is only illustrative and does not limit the utility model and its application or use. Based on the description of the utility model, all other technical solutions obtained by ordinary technicians in this field without creative labor are within the scope of protection of the utility model.

[0032] For ease of description, the present invention uses spatially relative terms, such as "above", "above", "on the upper surface of", "above", etc., to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figures. It should be understood that the spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above" or "above" will be positioned as "below" or "below". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0033] like Figure 1 As shown, the first aspect of the utility model is a lamp tube heater, comprising: a heater body 1 , an electrode 2 , an insulating ring 3 , a lamp tube 4 , an upper connecting piece 5 , a lower connecting piece 6 , and a reflecting plate 7 .

[0034] The heater body 1 is ring-shaped and is used for conducting electricity. A metal ring is also built into the heater body. The metal ring can be, for example, a copper ring, but is not limited thereto, and can also be other suitable metal rings.

[0035] An insulating ring 3 for insulation is provided on the upper side of the heater body 1 for insulation. Preferably, the insulating ring is a ceramic ring, but is not limited thereto and may also be other suitable insulating devices. An electrode 2 is provided inside the insulating ring 3 for supplying power to the lamp heater.

[0036] The reflective plate 7 is disposed on the lower side of the heater body 1 to radiate heat, thereby improving the heating efficiency. A plurality of lamp tubes 4 arranged in a fan shape on the reflective plate 7 are disposed on the lower side of the heater body 1 to emit heat for heating. Preferably, the distances between adjacent lamp tubes 4 are equal, so that the evenly distributed lamp tubes 4 can make heating more uniform. Preferably, the number of lamp tubes 4 is 20-60, but it is not limited thereto, and it can also be other suitable numbers as needed.

[0037] A lower connector 6 is provided below each lamp tube 4 and an upper connector 5 is provided above the upper portion, and the lower connector 6 and the upper connector 5 are used to connect the lamp tubes. The upper connector 5 is preferably made of insulating material, and more preferably ceramic material. The lower connector 6 is preferably made of metal, and more preferably stainless steel. After the heater has been used for a certain period of time, the surface of the electrode will show varying degrees of wear. If the wear is uneven, it will lead to uneven distribution of the electrode surface area, which will make arcing more likely to occur. The arcing phenomenon refers to the voltage exceeding the tolerance of the air, causing the air to ionize and become a conductor, that is, to generate an arc. This arc will bypass the insulator and be generated along the surface of the insulator, thereby damaging the insulator. When the upper connector 5 is made of ceramic material, the insulation effect is better and arcing can be prevented.

[0038] The second aspect of the utility model is a side wall passivation coating device, which comprises the lamp tube heater involved in the first aspect of the utility model. The lamp tube heater is arranged to heat from the side wall of the cavity.

[0039] The lamp tube heater of the utility model is used for the coating process of the coating equipment. After testing, the heating time is shortened from more than 1 hour to about 10 minutes. The setting is simple and the process is convenient, the heating cost is reduced and the production efficiency is improved.

[0040] Although the embodiments of the present invention are described in detail above, it is obvious to those skilled in the art that various modifications and variations can be made to these embodiments. However, it should be understood that such modifications and variations are within the scope and spirit of the present invention as described in the claims. Moreover, the present invention described herein may have other embodiments and may be implemented or realized in a variety of ways.
