[0034] In the embodiment, the supporting frame 102 is fixedly connected with the bottom plate 101, which helps to provide a stable supporting structure, so that the whole lamp box is more stable and reliable during use.

[0035] The fixed plate 106 can slide on the supporting frame 102 to clamp the edge strip on one side of the oil painting. In the initial state, the fixed plate 106 is in the raised state, the limiting block 107 enters the limiting groove 111, after the oil painting is placed, the control rod 109 is pulled to control the limiting block 107 to leave the limiting groove 111, and at the moment the fixed plate 106 moves downward under the action of the first elastic element 110 to clamp the edge strip on one side of the oil painting. The sliding clamping plate 104 is designed to better adapt to oil painting works of different sizes. The sliding block 112 can freely slide on the supporting frame 102 to adapt to oil paintings of different widths. The locker 113 is installed on the sliding block 112 and can fix the oil painting by locking the position of the sliding block 112. The pressing plate 114 can slide on the sliding block 112, and in cooperation with the second elastic element 115, the oil painting can be effectively and flatly pressed to avoid movement or damage during detection or repair.

[0036] Finally, the lighting assembly 105 is arranged below the base plate 101, providing uniform and sufficient light source for the oil painting, helping the restorer to observe the details of the painting more accurately and improving the quality and efficiency of the restoration work.

[0037] The fixed clamping plate 103 also includes a damping spring 116, which is fixed on the base plate 101 and located below the fixed plate 106.

[0038] This damping spring 116 is fixed on the base plate 101 and located below the fixed plate 106. Its role is to provide additional cushioning and support for the fixed plate 106, ensuring that the position of the fixed plate 106 can be adjusted more smoothly, reducing the risk of vibration or accidental movement, thereby better protecting the oil painting being restored.

[0039] The sliding block 112 includes a sliding block body 117, a temperature detection unit 118, and a heat dissipation unit 119. The temperature detection unit 118 is arranged on the sliding block body 117 and is close to the lighting assembly 105. The heat dissipation unit 119 is arranged on the sliding block body 117.

[0040] The sliding block body 117 serves as the basic structure, carrying these additional functional modules. The temperature detection unit 118 is arranged on the sliding block body 117 and is intentionally close to the lighting assembly 105. This design is to monitor the temperature changes inside the light box, especially near the lighting assembly 105, in real time, to prevent potential damage to the oil painting due to overheating. Once an abnormal temperature rise is detected, timely measures can be taken for adjustment.

[0041] The heat dissipation unit 119 includes a heat dissipation fan 120, a rotating block 121, and a rotating motor 122. The rotating block 121 is rotatably arranged below the sliding block body 117. The output end of the rotating motor 122 is connected to the rotating block 121. The heat dissipation fan 120 is arranged on the rotating block 121.

[0042] The rotating block 121 is installed below the sliding block body 117 and can rotate freely. The output end of the rotating motor 122 is connected to the rotating block 121. The rotating block 121 is driven to rotate by the motor, thereby changing the direction of the heat dissipation fan 120. The heat dissipation fan 120 is installed on the rotating block 121. In this way, the position and direction of the fan can be flexibly adjusted according to actual needs, achieving efficient heat dissipation effect, ensuring that the temperature inside the light box always remains within a suitable range, which is beneficial for the protection of the oil painting and helps to prolong the service life of the equipment.

[0043] The locking device 113 comprises a handle 123 and a pressing rod 124, the handle 123 is screwed on the sliding block 112, and the pressing rod 124 is slidingly arranged on the sliding block 112 and rotationally connected with the handle 123.

[0044] The locking device 113 first comprises a handle 123 for easy operation, which is installed on the sliding block 112 by screwing. This design allows the user to accurately adjust the up and down movement of the pressing rod 124 by rotating the handle 123, so as to push the sliding block 112 to move downward to clamp the other side of the oil painting.

[0045] The locking device 113 further comprises a friction pad 125 fixed to the bottom of the pressing rod 124.

[0046] The main function of the friction pad 125 is to increase the friction between the pressing rod 124 and the contact surface of the oil painting, thereby improving the reliability of the fixation. Due to the presence of the friction pad 125, a more stable pressing effect can be provided without damaging the surface of the oil painting.

[0047] The pressing plate 114 comprises a pressing plate body 126, a support plate 127 slidingly arranged on the sliding block 112, and a tension adjuster 128 for adjusting the position of the support plate 127.

[0048] The pressing plate body 126 is the part that directly contacts the oil painting, and it is slidingly arranged below the support plate 127. This design allows the pressing plate body 126 to be adjusted up and down according to the actual thickness of the oil painting, ensuring that the canvas can be pressed gently and stably, avoiding any pressure points or friction that may damage the oil painting. The support plate 127 is slidingly arranged on the sliding block 112, and the support plate 127 can be adjusted in position along the sliding block 112, so that after clamping the oil painting, the clamping position of the oil painting can be fine-tuned by the tension adjuster 128 to flatten the oil painting, thereby facilitating the repair.

[0049] The lighting assembly 105 comprises a plurality of lighting units 129, a plurality of photoelectric sensing units 130, a shielding area detection unit 131, and a lighting control unit 132; a plurality of the lighting units 129 are arranged below the bottom plate 101, and a plurality of the photoelectric sensing units 130 are distributed below the bottom plate 101 for detecting shielding signals; the shielding area detection unit 131 is used to calculate the shielding area based on the shielding signals, and the lighting control unit 132 is used to control the lighting units 129 in the above-mentioned shielding area to illuminate.

[0050] A plurality of lighting units 129 are arranged below the base plate 101. These lighting units 129 are evenly distributed, aiming to provide sufficient and uniform light source for the oil painting placed on it. This layout helps to eliminate shadows and reflections, enabling the restorer to clearly observe every detail of the oil painting, thus performing precise repair operations. A plurality of photoelectric sensing units 130 are also distributed below the base plate 101, working in coordination with the lighting units 129. The main task of the photoelectric sensing units 130 is to detect any obstruction signals that may affect the uniformity of light in real time. For example, when the restorer's hand or tool enters the lighting area, the photoelectric sensing units 130 can immediately capture this change and transmit the signal to the subsequent processing unit. In order to accurately identify and respond to these obstruction signals, the system is equipped with a dedicated obstruction area detection unit 131. Based on the data received from the photoelectric sensing units 130, this unit calculates the specific obstruction area through an algorithm. This means it can accurately determine which parts of the lighting are disturbed, so that appropriate measures can be taken to optimize the lighting effect. The lighting control unit 132 is responsible for dynamically adjusting the working state of the lighting units 129 in the corresponding area according to the information provided by the obstruction area detection unit 131. If a certain area is obstructed, the lighting control unit 132 can reduce or turn off the lighting in that area, avoiding unnecessary energy consumption and potential light heat effects on the oil painting; at the same time, it can enhance the lighting intensity of the unobstructed area to maintain the balance and consistency of the overall lighting. In this way, not only the energy utilization efficiency is improved, but also the restorer can always work in an ideal lighting environment.

[0051] The tension regulator 128 comprises an adjusting screw 133, an adjusting motor 134, a pressure sensor 135 and a control unit 136, the adjusting screw 133 is rotationally connected with the sliding block body 117 and is threadedly connected with the pressing plate body 126, the output end of the adjusting motor 134 is connected with the adjusting screw 133, the pressure sensor 135 is arranged on the adjusting motor 134 and the sliding block body 117, and the control unit 136 is connected with the pressure sensor 135 and the adjusting motor 134.

[0052] The adjusting screw 133 is one of the key mechanical components of the tension regulator 128, which is rotationally connected with the sliding block body 117 and threadedly connected with the pressing plate body 126. This design allows the adjusting screw 133 to move the pressing plate body 126 left and right when rotating, thereby adjusting the tension of the oil painting surface. It is convenient to flatten the oil painting.

[0053] The output end of the adjusting motor 134 is directly connected to the adjusting screw 133. This means that when it is necessary to adjust the position or the pressure exerted by the pressing plate 114, the adjusting screw 133 can be driven to rotate by the adjusting motor 134, thereby achieving precise control over the height of the pressing plate 114. This electric adjustment method not only improves operational efficiency, but also enables users to make subtle adjustments more conveniently, avoiding the inaccuracy that may be caused by manual adjustment. In order to ensure that the pressure exerted on the oil painting is always within a safe range, the tension adjuster 128 is also equipped with a pressure sensor 135. This sensor is arranged on the adjusting motor 134 and the sliding block body 117, and is used to monitor the pressure changes occurring during the adjustment process in real time. This helps to prevent the oil painting from being damaged due to excessive pressure, and also ensures that the pressing plate 114 can stably hold the position of the oil painting under appropriate pressure. The control unit 136 receives data from the pressure sensor 135 and intelligently controls the action of the adjusting motor 134 based on these data. For example, if it is detected that the pressure exceeds the preset safe range, the control unit 136 can immediately instruct the adjusting motor 134 to adjust the speed or direction in order to reduce the pressure to a safe level. In addition, the control unit 136 can also store different set values in order to quickly switch to the most suitable pressing parameters for different types of oil paintings.

[0054] Second embodiment

[0055] Please refer to Figure 9 The present application also provides a control method for an oil painting detection light box for art restoration, comprising:

[0056] S201 The photoelectric sensing unit 130 detects the blocking signal;

[0057] At this stage, the multiple photoelectric sensing units 130 arranged below the bottom plate 101 begin to work. These photoelectric sensing units 130 are responsible for monitoring in real time whether there is an obstruction above the light box, such as the restorer's hand, tools or any other object that may affect the uniform distribution of light. The photoelectric sensing unit 130 identifies whether there is an obstruction by sensing changes in light, and converts this change into an electrical signal, i.e. the so-called blocking signal. This process is continuous to ensure that any newly appearing obstruction can be quickly captured.

[0058] S202 The blocking area detection unit 131 calculates the blocking area based on the blocking signal;

[0059] Once the occlusion signal is detected by the photoelectric sensing unit 130, the next task is handed over to the occlusion area detection unit 131. This unit receives data from the photoelectric sensing unit 130 and processes these data using pre-programmed algorithms to determine the specific location and size of the occlusion. This step involves complex image processing techniques, which accurately calculate the location and range of the occlusion area by comparing the baseline value under normal lighting conditions with the current detected light changes. Such design enables the system to intelligently adapt to different operating scenarios, accurately identifying the shape and size of the occlusion.

[0060] The lighting control unit 132 controls the lighting unit 129 in the above-mentioned occlusion area according to the information provided by the occlusion area detection unit 131.

[0061] Finally, after determining the occlusion area, the lighting control unit 132 will dynamically adjust the working state of the lighting unit 129 in the corresponding area according to the information provided by the occlusion area detection unit 131. Specifically, if a certain area is occluded, the lighting control unit 132 may reduce or turn off the lighting in that area to avoid unnecessary energy consumption and possible local overheating problems caused by excessive lighting. At the same time, it will enhance the lighting intensity in the unoccluded area to maintain the balance and consistency of the overall lighting. This intelligent lighting adjustment not only improves energy efficiency, but also ensures that the repairer always works in an ideal and safe lighting environment, helping to improve the quality and accuracy of repair work.

[0062] The above only discloses one preferred embodiment of the present application, of course, cannot limit the scope of the present application, those skilled in the art can understand the implementation of all or part of the above-mentioned processes, and the equivalent changes made according to the claims of the present application, still belong to the scope covered by the present application.
