[0002] The cavity wax injection technology is to inject a certain amount of liquid wax into the bottom of the vehicle body and other steel plate interlayers and cavities. Through a specific process flow, the wax remaining inside the vehicle body cavity forms a uniform protective wax film, thereby preventing moisture from remaining in the vehicle body cavity, causing internal corrosion of the vehicle body, and improving the anti-corrosion performance of the whole vehicle. The implementation of the wax injection process not only ensures the anti-corrosion performance of the vehicle, but also enhances the resistance of the vehicle body, making the anti-rust ability of the vehicle body reach more than 10 years.

[0003] In order to carry out the wax injection process in the wax injection station orderly, timely and completely, it is necessary to display and prompt the information during the wax injection process in real time. When the existing wax injection station displays the information during the wax injection process, it installs indicator lights inside the wax injection chamber to prompt the wax injection operator to use the corresponding tooling, or installs a non-explosion-proof display device outside the wax injection chamber for display. However, the existing indicator light display method can display very little content about the wax injection process, which is not convenient for employees to operate; and the display result is fixed and not intelligent enough; in addition, the installation position outside the wax injection chamber is limited by the chamber structure of the wax injection station, farther from the operator, inconvenient to view, and wax mist will adhere to the chamber glass during production, resulting in poor visual effects.

[0007] The edge of the display is at a preset length from the side wall of the explosion-proof box, and the display interface of the display is at a preset height from the top wall of the explosion-proof box.

[0008] The beneficial effects of this solution are:

[0009] By setting the display inside the explosion-proof box and installing the explosion-proof box in the wax injection workshop, it is possible to conveniently view the wax injection information displayed on the display while providing explosion protection for the display, reducing the interference suffered by the display in the special environment of the wax injection workshop, enabling the display to work stably, and maintaining the heat dissipation of the display to prevent the temperature inside the explosion-proof box from being too high.

[0020] The reference numerals in the accompanying drawings of the specification include: explosion-proof box 1, display 2, mounting bracket 3, mounting pipe column 4, annular groove 5, and glass window 6.

[0021] Embodiment

[0022] An intelligent explosion-proof display device for a wax injection station, as Figure 1 shown: It includes an explosion-proof box 1 located on the inner wall of the wax injection workshop and a display 2 for displaying various wax injection information. The display 2 is located inside the explosion-proof box 1. The explosion-proof box 1 is in the shape of a cuboid. The display 2 is an HMI device, and the explosion-proof box 1 is an aluminum alloy box body.

[0023] The display 2 is signal-connected to a PLC controller for transmitting wax injection information. The PLC controller uses existing products according to actual production requirements. The PLC controller is signal-connected to a wax injection device for uploading wax injection information. The wax injection information includes, for example, wax injection vehicle model information, tooling information used for the vehicle model information, actual tooling information, wax injection volume set by the used tooling, actual wax injection volume after wax injection is completed, number of times of wax injection required for the current vehicle model at the station, number of times of wax injection that has been completed at the current station, etc. The wax injection information is selected according to actual requirements.

[0024] The edge of the display 2 is at a preset length from the side wall of the explosion-proof box 1, and the display interface of the display 2 is at a preset height from the top wall of the explosion-proof box 1. The preset length and preset height are set according to the actual sizes of the display 2 and the explosion-proof box 1.

[0025] As Figure 3 shown, the length of the display 2 is 330 mm, the width of the display 2 is 241 mm, and the thickness of the display 2 is 70.5 mm; as Figure 2 shown, the inner wall width of the explosion-proof box 1 is 337 mm, the inner wall length of the explosion-proof box 1 is 437 mm, and the inner wall depth of the explosion-proof box 1 is 167 mm. From the specific sizes of the display 2 and the explosion-proof box 1, the preset distance can be obtained as 53.5 mm at the long side and 48 mm at the short side, and the preset height is 96.5 mm. To ensure the heat dissipation space of the display 2.

[0026] The maximum operating temperature of the HMI device is 55 °C. Although the external environment temperature where the device is used is lower than 35 °C, after being installed in the explosion-proof box 1, the HMI will also generate heat during operation. Therefore, the size of the explosion-proof box 1 is increased to form a larger internal space, so that the HMI device has sufficient heat dissipation space inside the explosion-proof box 1. After the HMI device runs continuously for 24 hours at an ambient temperature of 35 °C, measure its internal temperature not higher than 45 °C. Effective heat dissipation can be achieved through the setting of the size of the explosion-proof box 1.

[0027] A glass window 6 is hermetically connected to the display interface of the explosion-proof box 1 facing the display 2. An anti-fog coating is applied to the side wall of the glass window 6 facing the display 2. The anti-fog coating is an anti-fog coating rich in conductive material ITO and silicon oxide. The use environment has a relatively high humidity, and the temperature inside the box is higher than the external environment temperature during use. In winter, the inner side glass of the box is prone to fogging. With the setting of the anti-fog coating, effective defogging can be carried out in winter. To meet the IP65 sealing grade, a sealing strip and a groove are designed around the gap of the explosion-proof box 1. The rubber strip is placed in the groove and fixed in a porous manner.

[0028] A plurality of mounting brackets 3 are welded on the explosion-proof box 1. There are four mounting brackets 3. Every two of the mounting brackets 3 are on the opposite sides of the mounting brackets 3, and the mounting brackets 3 are located at the two side edge ends. Mounting holes for screwing the screws are provided on the mounting brackets 3. The mounting brackets 3 are located at the width side edges of the explosion-proof box 1.

[0029] An installation pipe column 4 through which the wire of the display 2 passes is welded on the bottom end of the explosion-proof box 1. The installation pipe column 4 is cylindrical. A ring groove 5 for sealing is provided at the end of the installation pipe column 4 away from the explosion-proof box 1. The depth of the ring groove 5 is set according to the actual sealing requirements. For example, the depth of the ring groove 5 is set to 2 mm.

[0030] The specific implementation process is as follows:

[0031] Since there are flammable and explosive substances in the wax liquid, the wax injection chamber belongs to the explosion-proof area. If the display 2 is directly installed in the wax injection chamber, the display 2 is easily interfered with and cannot work properly; if the display 2 is installed outside the wax injection chamber, it is not convenient to view the content on the display 2. Therefore, in this embodiment, the display 2 is installed in the explosion-proof box 1 to isolate the display 2 from the interference of the internal environment of the wax injection chamber. Also, through the size settings of the explosion-proof box 1 and the display 2, on the premise of keeping the explosion-proof box 1 beautiful, the display 2 can effectively dissipate heat in the explosion-proof box 1. The settings of the explosion-proof box 1 and the display 2 can display the information required for wax injection, facilitate the employees to view and operate, and prevent the glass window 6 from fogging due to the temperature difference between the internal and external environments during winter use.

[0032] The above are only the embodiments of the present utility model. Common general knowledge such as the specific structures and characteristics in the solutions is not described in detail here. It should be noted that for those skilled in the art, without departing from the structure of the present utility model, several deformations and improvements can still be made, which should also be regarded as the protection scope of the present utility model, and these will not affect the implementation effect of the present utility model and the practicality of the patent. The protection scope required by this application should be based on the content of its claims, and the specific implementation manners and the like recorded in the description can be used to explain the content of the claims.
