[0095] In this embodiment, as shown in Figure 2 During the curing process, the automobile spoiler plate is bent, and the upper surface of the automobile spoiler plate is divided into the first bending area 141, the second bending area 142, and the third bending area 143, and the height and the inclination angle of the first ultraviolet lamp 21, the second ultraviolet lamp 22, and the third ultraviolet lamp 23 are adjusted according to the curing conditions of the first bending area 141, the second bending area 142, and the third bending area 143.

[0096] As shown in Figure 8 As shown in Figure 10 During the curing process, the automobile spoiler plate is inclined and placed on the fixed tooling 12, and moves together with the fixed tooling 12, so the second ultraviolet lamp 22 and the fourth ultraviolet lamp 24 are also inclined and irradiated, as shown in Figure 6 As shown in

[0097] In this embodiment, the light source of the ultraviolet curing channel, the irradiation time of the automobile spoiler plate, and the curing temperature of the ultraviolet curing channel are excluded first, and the remaining curing effect is related to the distance and angle of the ultraviolet lamp to the surface of the automobile spoiler plate; if the distance of the ultraviolet lamp to the surface of the automobile spoiler plate is too close, the surface of the automobile spoiler plate is prone to yellowing and cracking (excessive energy), and if the distance of the ultraviolet lamp to the surface of the automobile spoiler plate is too far, the surface of the automobile spoiler plate is prone to sticking and poor adhesion; the angle of the ultraviolet lamp needs to be directly opposite each part of the automobile spoiler plate, otherwise the curing effect in the middle is good and the curing effect on both sides is poor; the height and vertical inclination angle of the first ultraviolet lamp 21, the second ultraviolet lamp 22, and the third ultraviolet lamp 23 need to be adjusted according to different automobile spoiler plates;

[0098] In this embodiment, the two ends of the first ultraviolet lamp 21 are respectively provided with a first lifting unit 211, and the two first lifting units 211 are simultaneously extended downward, so that the two ends of the first ultraviolet lamp 21 are close to the first bending area 141 together; the left first lifting unit 211 is extended downward, and the right first lifting unit 211 is not moved, so as to change the vertical inclination angle of the first ultraviolet lamp 21, so that the first ultraviolet lamp 21 is as parallel to the first bending area 141 as possible, and the curing effect of the first bending area 141 is improved;

[0101] According to the curing effect of the first bending area 141, the second bending area 142, and the third bending area 143, the distance and inclination angle of the first ultraviolet lamp 21, the second ultraviolet lamp 22, and the third ultraviolet lamp 23 to the automobile spoiler plate are adjusted;

[0102] The embodiment divides the upper surface of the automobile spoiler plate into a first bending area 141, a second bending area 142 and a third bending area 143, directs the first ultraviolet lamp 21 towards the first bending area 141, the second ultraviolet lamp 22 towards the second bending area 142, and the third ultraviolet lamp 23 towards the third bending area 143; fixes the light source of the ultraviolet curing channel 27, the irradiation time of the automobile spoiler plate and the curing temperature of the ultraviolet curing channel 27, performs curing test first, detects the curing effect of the first bending area 141, the second bending area 142 and the third bending area 143 of the upper surface of the automobile spoiler plate respectively after curing, adjusts the height of the first ultraviolet lamp 21, the inclination angle of the first ultraviolet lamp 21 with the vertical direction according to the curing effect of the first bending area 141 through two first lifting units 211, adjusts the height of the second ultraviolet lamp 22, the inclination angle of the second ultraviolet lamp 22 with the vertical direction according to the curing effect of the second bending area 142 through two second lifting units 221, and adjusts the height of the third ultraviolet lamp 23, the inclination angle of the third ultraviolet lamp 23 with the vertical direction according to the curing effect of the third bending area 143 through two third lifting units 231 until the curing effects of the first bending area 141, the second bending area 142 and the third bending area 143 are all qualified, and then the automobile spoiler plate to be cured is added into the ultraviolet curing channel 27 after adjustment for curing;

[0103] Therefore, since the cross-sectional shape of the automobile spoiler plate is arc-shaped, three irradiation areas are designed according to the cross-sectional shape of the automobile spoiler plate, three ultraviolet rays are designed to be directed towards the three irradiation areas of the automobile spoiler plate, the automobile spoiler plate is placed into the ultraviolet curing channel 27 for test, and the height and inclination angle of the first ultraviolet lamp 21, the second ultraviolet lamp 22 and the third ultraviolet lamp 23 are adjusted according to the curing effect of the three irradiation areas of the automobile spoiler plate, so that the distance and angle between the ultraviolet lamp and the automobile spoiler plate can be adjusted, the curing effect of the upper surface of the automobile spoiler plate is improved, the curing effect of all areas of the upper surface of the automobile spoiler plate reaches the qualified standard, the height and inclination angle of the first ultraviolet lamp 21, the second ultraviolet lamp 22 and the third ultraviolet lamp 23 can be adjusted in time for different models of automobile spoiler plates without stopping to adjust the height and inclination angle of the ultraviolet lamp, different sizes of automobile spoiler plates can be adapted, and the production efficiency is improved.

[0104] According to some embodiments of the present application, in the S3 step, the energy values of the first ultraviolet lamp 21, the second ultraviolet lamp 22 and the third ultraviolet lamp 23 are detected by the energy detection device 3 respectively, and if the energy values of the first ultraviolet lamp 21, the second ultraviolet lamp 22 and the third ultraviolet lamp 23 exceed the preset range, the machine is stopped and an alarm is given;

[0105] By controlling the transmission speed of the upper conveying belt 2 and the operating state of the first blocking mechanism 9, the irradiation time of the automobile spoiler plate is controlled within a preset range.

[0106] The curing temperature of the ultraviolet curing channel 27 is detected by the temperature sensor 5, and the air blower 6 and the exhaust fan 7 are controlled to make the curing temperature of the ultraviolet curing channel 27 within a preset range.

[0107] The energy detection device 3 is the core detection tool of ultraviolet (UV) curing, and the detection content is around the energy, intensity, and spectral characteristics of ultraviolet light. The specific principle is a conventional technical means, which will not be described in detail here.

[0108] By controlling the transmission speed of the upper conveying belt 2 and the operating state of the first blocking mechanism 9, the irradiation time of the automobile spoiler plate is controlled within a preset range.

[0109] By blocking the two light-blocking rubber 26, the curing temperature in the ultraviolet curing channel 27 is maintained within a certain range, and the curing temperature in the ultraviolet curing channel 27 can be controlled by the air blower 6 and the exhaust fan 7 for ventilation and heat dissipation.

[0110] In this way, the energy values of the first ultraviolet lamp 21, the second ultraviolet lamp 22, and the third ultraviolet lamp 23 are detected by the energy detection device 3. The energy detection device 3 quantifies the energy output of the ultraviolet light source, ensures that the energy, intensity, and spectrum of the ultraviolet light source output meet the curing requirements of the material, and monitors the operation of the ultraviolet lamp. By controlling the transmission speed of the upper conveying belt 2 and the operating state of the first blocking mechanism 9, the irradiation time of the automobile spoiler plate is controlled. The temperature sensor 5 cooperates with the air blower 6 and the exhaust fan 7 to ensure that the curing temperature is within a preset range, avoiding the problem of poor curing effect caused by too high or too low curing temperature, and eliminating the influence of light source, curing temperature, and irradiation time on the curing effect.

[0111] According to some embodiments of the present application, the fourth ultraviolet lamp 24 is optionally installed in the ultraviolet curing channel 27, and the fourth ultraviolet lamp 24 faces the second bending area 142. The automobile spoiler plate passes through the second ultraviolet lamp 22, the first ultraviolet lamp 21, the third ultraviolet lamp 23, and the fourth ultraviolet lamp 24 in sequence. The energy value of the fourth ultraviolet light is detected by the energy detection device 3. If the energy value of the fourth ultraviolet light exceeds the preset range, the machine is stopped and an alarm is given.

[0112] The fourth ultraviolet lamp 24 has a length and a principle similar to those of the second ultraviolet lamp 22. The fourth ultraviolet lamp 24 is provided with a fourth lifting unit at each end. When the two fourth lifting units are simultaneously lowered, the two ends of the fourth ultraviolet lamp 24 are close to the second bending area 142. When one fourth lifting unit is lowered and the other fourth lifting unit is not moved, the inclination angle of the fourth ultraviolet lamp 24 in the vertical direction is changed, and the curing effect of the second bending area 142 is improved.

[0113] The fourth ultraviolet lamp 24 and the second ultraviolet lamp 22 face two different directions, and the fourth ultraviolet lamp 24 expands the curing range.

[0114] Therefore, since the second bending area 142 of the automobile spoiler plate is relatively long, in order to improve the curing effect of the second bending area 142 of the automobile spoiler plate, the second ultraviolet lamp 22 and the fourth ultraviolet lamp 24 can be used for irradiation twice. Meanwhile, the second ultraviolet lamp 22 and the fourth ultraviolet lamp 24 face different directions, and can irradiate the second bending area 142 from two different directions. Thus, the two sides of the second bending area 142 can be cured at the same time, and the curing effect is improved.

When the two fourth lifting units are simultaneously extended downward, the two ends of the fourth ultraviolet lamp 24 approach the second bending area 142 together. When the left and right fourth lifting units are used, one fourth lifting unit is extended downward, and the other fourth lifting unit is not moved, thereby changing the inclination angle of the fourth ultraviolet lamp 24 in the vertical direction.

[0138] In this way, the orientation of the second ultraviolet lamp 22 can be adjusted by the first rotating mechanism 25, and the orientation of the fourth ultraviolet lamp 24 can be adjusted by the second rotating mechanism, so that the fourth ultraviolet lamp 24 and the second ultraviolet lamp 22 are oriented in two different directions to comprehensively cure the automobile spoiler and improve the curing effect.

[0143] Therefore, during use, the distance between the first ultraviolet lamp 21 and the first energy detection device 31 is equal to the distance between the first ultraviolet lamp 21 and the automobile spoiler to be cured, the distance between the second ultraviolet lamp 22 and the second energy detection device 32 is equal to the distance between the second ultraviolet lamp 22 and the automobile spoiler to be cured, the distance between the third ultraviolet lamp 23 and the third energy detection device 33 is equal to the distance between the third ultraviolet lamp 23 and the automobile spoiler to be cured, and the distance between the fourth ultraviolet lamp 24 and the fourth energy detection device 34 is equal to the distance between the fourth ultraviolet lamp 24 and the automobile spoiler to be cured. When the height, orientation, and inclination angle of the first ultraviolet lamp 21, the second ultraviolet lamp 22, the third ultraviolet lamp 23, and the fourth ultraviolet lamp 24 are adjusted, the position of the first energy detection device 31 and the second energy detection device 32 can be adjusted through the first track 35, and the position of the third energy detection device 33 and the fourth energy detection device 34 can be adjusted through the second track 36.

The positioning mechanism positions both ends of the fixed tooling 12. The positioning mechanism is a limiting rail arranged on both sides of the ultraviolet curing channel 27. The two ends of the base of the fixed tooling 12 are limited in the limiting rails on both sides, so that the fixed tooling 12 always maintains a state in the upper conveying belt 2 for transportation, ensuring that the position and angle of the automobile spoiler plate on the fixed tooling 12 will not move, avoiding the left and right movement of the fixed tooling 12 on the upper conveying belt 2 and the lower conveying belt 10, and affecting the curing effect.
