DETAILED DESCRIPTION

[0040] In the following description, numerous specific details are provided in order to provide a thorough understanding of the present application. One of ordinary skill in the art will realize, however, that the application can be practiced without one or more of these details. In other instances, well-known features have not been described in detail in order not to unnecessarily obscure the present application.

[0041] For a thorough understanding of the present application, reference will be made to the following detailed description. It is appreciated that the present application can be carried out by anyone skilled in the art without undue experimentation, given the benefit of this disclosure. The present application is described in enough detail to enable those skilled in the art to practice the application. The embodiments of the present application can be combined with other embodiments unless otherwise specified.

[0042] The embodiment of the present application provides a shooting device. The shooting device can be applied to a laser processing equipment. The shooting device according to the embodiment of the present application will be described in detail below with reference to the drawings.

[0043] With reference to the drawings Figures 1 to 4 The shooting device 1 can include a camera assembly 10, a laser source assembly 20 and a first reflecting element 30. The camera assembly 10 can have a shooting light path 111 for shooting materials. The laser source assembly 20 can be used for emitting a first light beam. The first light beam can be a laser or the like. The first reflecting element 30 can be arranged on the shooting light path 111. The first reflecting element 30 has an included angle with the shooting light path 111, for example, the included angle is 45 degrees. The first light beam can be reflected by the first reflecting element 30 and then reach the materials along a first path 310. It should be noted that the first reflecting element 30 can be an optical lens, for example, a mirror or the like. The shooting light path 111 can be coaxial with the first path 310. The camera assembly 10 can include a camera 110, a first light path assembly 120 and a camera adjusting assembly 130. The camera adjusting assembly 130 and the first light path assembly 120 can be sequentially arranged along the shooting light path 111. The camera 110 can be connected to the side of the camera adjusting assembly 130 away from the first light path assembly 120. An active gap 140 can be formed between the outer wall of the first light path assembly 120 and the inner wall of the camera adjusting assembly 130. The relative position relationship between the camera 110 and the first light path assembly 120 can be adjusted by changing the size of the active gap 140.

[0044] The camera 110 can shoot the materials. The shooting light path 111 of the camera 110 can pass through the first light path assembly 120 to reach the materials. The first light path assembly 120 and the materials can have a relatively fixed position relationship to obtain the image of the materials.

[0045] The side of the camera adjusting assembly 130 away from the camera 110 can be sleeved on the first light path assembly 120, so that the inner wall of the camera adjusting assembly 130 and the outer wall of the first light path assembly 120 form the active gap 140. When the camera assembly 10 is arranged in the vertical direction, the camera adjusting assembly 130 has a certain degree of freedom in the horizontal direction relative to the first light path assembly 120 through the active gap 140. Thus, the relative position relationship between the camera 110 connected to the camera adjusting assembly 130 and the first light path assembly 120 can be adjusted, so as to ensure the shooting effect of the camera 110.

[0046] The material can be a wafer, specifically a silicon wafer used for manufacturing silicon semiconductor integrated circuits, and the shape can be circular. Various circuit element structures can be processed on the silicon wafer to become products with specific electrical properties. The wafer is fragile and easy to scratch, especially ultra-thin wafer processing, which has high requirements for heat. The laser source assembly 20 can emit a first light beam, which is reflected by the first reflecting element 30 along the first path 310 to the wafer and finally focused inside the wafer cutting path. The energy focus generates high temperature, which can realize the wafer stealth cutting, that is, a burst point is generated inside the wafer cutting path, and a crack is generated by connecting multiple points, so as to separate the wafer chip and achieve the cutting goal. In the processing process, no dust is generated, the wafer is not polluted, it is a non-contact processing, the heat influence is small, and the effect is very good for processing a wafer with a relatively small thickness.

[0047] In some other embodiments, an active gap 140 for adjusting the relative position relationship between the camera 110 and the first light path assembly 120 can be formed between the inner wall of the first light path assembly 120 and the outer wall of the camera adjusting assembly 130, which is not limited in the application.

[0048] The camera device 1 of the application, on the one hand, an active gap 140 can be formed between the outer wall of the first light path assembly 120 and the inner wall of the camera adjusting assembly 130, by adjusting the active gap 140, the relative displacement between the camera 110 connected with the camera adjusting assembly 130 and the first light path assembly 120 can be generated, and then the distance adjustment between the camera 110 and the material is realized, the mechanical structure of the camera device 1 is effectively simplified, the operation space occupied by the camera device 1 is reduced, the precision and miniaturization of the camera device 1 are realized, the manufacturing cost of the camera device 1 is reduced, the convenience of the operator is improved, on the other hand, when the camera device 1 of the application is applied to the laser processing assembly, since the shooting light path 111 is coaxial with the first path 310, the precision of the laser processing material can be improved by real-time shooting of the material by the camera assembly 10, so as to improve the processing quality and avoid waste caused by poor processing.

[0049] For reference Figure 3 and Figure 4The camera adjusting assembly 130 can include a first camera adjusting piece 131 and a second camera adjusting piece 132. The first camera adjusting piece 131 can be connected with the second camera adjusting piece 132. The first camera adjusting piece 131 and the second camera adjusting piece 132 can be detachably connected, which can include a plug-in connection or a threaded connection, etc. The present application does not make specific limitations on this. The first optical path assembly 120 and the first camera adjusting piece 131 can be movably connected to form a movable gap 140 therebetween. The second camera adjusting piece 132 can be connected with the camera 110. The relative position relationship between the camera 110 and the first optical path assembly 120 can be further adjusted through the first camera adjusting piece 131 and the second camera adjusting piece 132, which not only improves the shooting effect of the camera 110, but also simplifies the mechanical structure of the camera adjusting assembly 130 and reduces the operation space occupied by the camera adjusting assembly 130.

[0050] In combination with reference to Figure 4 and Figure 5 The first camera adjusting piece 131 can include a first limiting piece 1311 and a first sleeve body 1312. The first sleeve body 1312 can be sleeved on the outside of the first optical path assembly 120. The first limiting piece 1311 can be inserted through the first sleeve body 1312 and abut against the outer wall of the first optical path assembly 120, which can be used to adjust the movable gap 140. Specifically, the side wall of the first sleeve body 1312 can be provided with a first through hole, and the first limiting piece 1311 can pass through the first through hole on the first sleeve body 1312 and abut against the outer wall of the first optical path assembly 120, so as to adjust the relative position of the first camera adjusting piece 131 and the first optical path assembly 120. The first limiting piece 1311 can be a fastener, such as a screw or a bolt, etc. When the first limiting piece 1311 is located on the left side of the first sleeve body 1312 and needs to adjust the first camera adjusting piece 131 to the right, the first limiting piece 1311 can be tightened to reduce the left movable gap 140 and increase the right movable gap 140. Conversely, when the first limiting piece 1311 is located on the left side of the first sleeve body 1312 and needs to adjust the first camera adjusting piece 131 to the left, the first limiting piece 1311 can be loosened to reduce the right movable gap 140 and increase the left movable gap 140. In this way, the movable gap 140 between the outer wall of the first optical path assembly 120 and the inner wall of the camera adjusting assembly 130 can be flexibly adjusted through the first limiting piece 1311, which effectively simplifies the adjustment steps of the camera adjusting assembly 130 and improves the convenience of adjustment.

[0051] Further, the first limiting member 1311 can be in plurality, and the plurality of first limiting members 1311 can be arranged at intervals along the outer periphery of the first optical path assembly 120. Preferably, the first limiting member 1311 can be in three, and the included angle formed between every two first limiting members 1311 can be 120 degrees. By the three first limiting members 1311, the relative position relationship between the camera 110 and the first optical path assembly 120 can be accurately adjusted. By the cooperation between the plurality of first limiting members 1311, not only the relative position relationship between the camera 110 and the first optical path assembly 120 can be accurately adjusted, but also a firm connection relationship between the camera 110 and the first optical path assembly 120 can be formed, so that the positional deviation between the camera 110 and the first optical path assembly 120 in use can be avoided, and the practicability and reliability of the camera adjusting assembly 130 are effectively improved.

[0052] Referring to Figure 4 , the second camera adjusting member 132 can have a first connecting end and a second connecting end. The first connecting end can be rotationally connected with the first camera adjusting member 131. The second connecting end can be connected with the camera 110. The second camera adjusting member 132 can be used to drive the camera 110 to rotate in a first direction (such as the P-P direction in Figure 4 , and reciprocate in a second direction (such as the Q-Q direction in Figure 4 ). The first direction can be clockwise or counterclockwise, and the second direction can be away from or close to the first optical path assembly 120.

[0053] Alternatively, the side away from the camera 110 of the second camera adjusting member 132 can be sleeved outside the first camera adjusting member 131 and threadedly connected with the first camera adjusting member 131. Specifically, the outer wall of the first camera adjusting member 131 can be formed with external threads, and the inner wall of the side away from the camera 110 of the second camera adjusting member 132 can be formed with internal threads matched with the external threads. When the second camera adjusting member 132 is rotated, the second camera adjusting member 132 can drive the camera 110 to rotate in the clockwise direction or the counterclockwise direction, and also drive the camera 110 to rotate away from or close to the first optical path assembly 120.

[0054] Alternatively, the side away from the camera 110 of the second camera adjusting member 132 can be sleeved outside the first camera adjusting member 131 and plug-connected with the first camera adjusting member 131. Specifically, the outer wall of the first camera adjusting member 131 and the inner wall of the side away from the camera 110 of the second camera adjusting member 132 can be in abutment. By plugging and rotating the second camera adjusting member 132, the camera 110 can be rotated in the clockwise direction or the counterclockwise direction, and also rotated away from or close to the first optical path assembly 120.

[0055] In the above embodiment, the second camera adjusting member 132 can drive the camera 110 to rotate in the first direction and reciprocate in the second direction, which can further improve the adjustment range of the camera adjusting assembly 130, so that the camera 110 can meet different use scenarios, and further improve the flexibility of the camera adjusting assembly 130.

[0056] Again, refer to Figure 4 and Figure 5 The camera assembly 10 can further include a fixing part 150 rotationally connected to the outer wall of the first camera adjusting member 131. The fixing part 150 can have an upper end face 151. When the second camera adjusting member 132 rotates by a preset angle, the fixing part 150 can rotate so that the upper end face 151 abuts against the first connecting end. Specifically, the fixing part 150 can have a circular ring shape, and the circular ring-shaped fixing part 150 can be sleeved on the outer wall of the first camera adjusting member 131, and the position of the fixing part 150 is closer to the first light path assembly 120 than the second camera adjusting member 132. The outer wall of the first camera adjusting member 131 can be formed with external threads, and the inner wall of the fixing part 150 can be formed with internal threads matched with the external threads, so that the fixing part 150 can be rotationally connected to the outer wall of the first camera adjusting member 131. In this way, the second camera adjusting member 132 and the camera 110 are limited in the desired position, avoiding the positional deviation of the second camera adjusting member 132 and the camera 110 during use, effectively improving the firmness of the connection between the second camera adjusting member 132 and the first camera adjusting member 131, and further improving the overall firmness of the camera adjusting assembly 130.

[0057] Again, refer to Figure 4 and Figure 5The fixing part 150 can include a second limiting piece 152 and a second sleeve 153. The second sleeve 153 can be rotationally connected to the outer wall of the first camera adjusting piece 131. The second limiting piece 152 can be arranged through the second sleeve 153 and abut against the outer wall of the first camera adjusting piece 131. Specifically, the side wall of the second sleeve 153 can be provided with a second through hole, and the second limiting piece 152 can pass through the second through hole and abut against the outer wall of the first camera adjusting piece 131, so as to firmly fix the fixing part 150 to the outer wall of the first camera adjusting piece 131. The second limiting piece 152 can be a fastener, such as a screw or a bolt, and so on. Clockwise rotation of the second limiting piece 152 can connect the second sleeve 153 to the first camera adjusting piece 131, and vice versa, counterclockwise rotation of the second limiting piece 152 can disconnect the second sleeve 153 from the first camera adjusting piece 131. In this way, the second limiting piece 152 can firmly fix the second sleeve 153 to the outer wall of the first camera adjusting piece 131, so as to avoid the position deviation of the second camera adjusting piece 132 and the camera 110 after being subjected to external force, and further improve the overall firmness of the camera adjusting assembly 130.

[0058] In some embodiments, the first light path assembly 120 can be formed with a stepped portion 121 near one end of the first camera adjusting piece 131, and the first camera adjusting piece 131 can be located on the stepped portion 121. In this way, sufficient support force can be provided to the camera adjusting assembly 130 and the camera 110, which not only ensures the stability of the camera adjusting assembly 130 during adjustment, but also enables the camera 110 to have more stable shooting conditions, effectively improves the shooting effect of the camera 110, and the practicality and reliability of the camera adjusting assembly 130.

[0059] Again in combination with reference to Figures 1 to 4The light source assembly 40 can be provided beside the camera 110. The light source assembly 40 can include a light emitting piece 410 and a second light path assembly 420. The light emitting piece 410 can be used to emit a second light beam along a second path 411. The second light beam can be monochromatic light, mixed light, etc. The second light path assembly 420 can have a second reflecting piece 422 and a second reflection adjusting assembly 423. It should be noted that the second reflecting piece 422 can be an optical lens, such as a reflecting mirror, etc. The second reflecting piece 422 can be provided on the second path 411 to reflect the second light beam. The second reflection adjusting assembly 423 can be connected with the second reflecting piece 422 to adjust the reflection angle of the second light beam, so that the second light beam can be transmitted to the shooting light path 111 along a third path 421. Specifically, the light emitting piece 410 can emit the second light beam to the material to make the material brighter. The light emitting piece 410 can be an LED lamp or a laser emitter, etc. The type of the light emitting piece 410 is not limited in the present application. The user can determine the type of the light emitting piece 410 according to the actual use needs. The convex lens 430, the adjustable diaphragm 440 and the achromatic lens 450 can be sequentially provided on the second path 411 of the light emitting piece 410. The second light beam emitted by the light emitting piece 410 can sequentially pass through the convex lens 430, the adjustable diaphragm 440 and the achromatic lens 450 and enter the second reflecting piece 422. The convex lens 430 can focus the light beam emitted by the light emitting piece 410. The adjustable diaphragm 440 can adjust the amount of light, thereby controlling the exposure effect of the camera 110. The achromatic lens 450 can be used to correct the refraction difference of light beams of different wavelengths, reduce the chromatic aberration phenomenon, and ensure the color accuracy and clarity of the image shot by the camera 110. Through the joint action of the above-mentioned devices, the camera 110 can shoot high-quality images. The second reflecting piece 422 can receive the second light beam and reflect it outward at a certain angle. The second reflecting piece 422 can be a plane mirror, etc. The present application does not make specific limitation thereon. When the second reflection adjusting assembly 423 is adjusted, the second reflecting piece 422 can be deflected synchronously, thereby adjusting the reflection angle of the second light beam by the second reflecting piece 422, and the second light beam can be transmitted to the shooting light path 111 at a better angle and effect. The intersection of the third path 421 and the shooting light path 111 can be provided with a refracting mirror 460. The second light beam reflected by the second reflecting piece 422 can be refracted by the refracting mirror 460 to be coaxial with the shooting light path 111 to irradiate the material. In this way, when the light emitting piece 410 emits the second light beam to the second reflecting piece 422, the second reflection adjusting assembly 423 can continuously adjust the reflection angle of the second reflecting piece 422, so that the second light beam emitted by the light emitting piece 410 can converge into the shooting light path 111 of the camera 110, thereby meeting the lighting needs of the camera 110 shooting, effectively simplifying the mechanical structure of the shooting device 1, reducing the operation space occupied by the shooting device 1, realizing the precision and miniaturization of the shooting device 1, and improving the convenience of the operator.

[0060] With reference to Figure 3 , Figure 4 and Figure 7 , the second reflection adjusting assembly 423 can include a fixed seat 4231 and a first mounting plate 4232. The second reflection member 422 can be arranged on the first mounting plate 4232. The first mounting plate 4232 can be movably connected with the fixed seat 4231 to adjust the reflection angle of the second light beam. Specifically, the fixed seat 4231 can be in communication with the light emitting member 410 and the camera 110 respectively, and the second reflection member 422 can be connected with the fixed seat 4231 through the first mounting plate 4232. The second reflection member 422 and the first mounting plate 4232 can be detachably connected or integrally formed, and the detachable connection includes clamping connection or adhesive connection, etc., which is not limited in the present application. The side of the first mounting plate 4232 facing the fixed seat 4231 can have a groove matched with the second reflection member 422, and the second reflection member 422 can be clamped in the groove, so that a stable connection is formed between the second reflection member 422 and the first mounting plate 4232. In this way, the reflection angle of the second light beam can be adjusted while simplifying the mechanical structure of the second reflection adjusting assembly 423 and reducing the processing and manufacturing difficulty of the second reflection adjusting assembly 423.

[0061] With reference to Figure 4 , Figure 6 and Figure 7 , the fixed seat 4231 and the first mounting plate 4232 can enclose a light guide cavity 4233. The second reflection member 422 can be located in the light guide cavity 4233, and the light guide cavity 4233 can have a first portion 4233a located on the second path 411 and a second portion 4233b located on the third path 421. Specifically, the second reflection member 422 can have a reflection surface, and the reflection surface of the second reflection member 422 can be located in the light guide cavity 4233. The second light beam emitted by the light emitting member 410 can enter the second reflection member 422 through the first portion 4233a of the light guide cavity 4233, and the second light beam reflected by the second reflection member 422 can be transmitted to the shooting light path 111 through the second portion 4233b of the light guide cavity 4233. In this way, the fixed seat 4231 and the first mounting plate 4232 can form a light beam transmission path, and the second reflection member 422 can be located at the intersection of the first portion 4233a and the second portion 4233b, thereby effectively reducing the volume occupied by the second reflection adjusting assembly 423 and improving the layout rationality of the second reflection adjusting assembly 423.

[0062] With reference to Figure 1 , Figure 3 , Figure 7 and Figure 8The second reflection adjusting assembly 423 can include a plurality of first angle adjusting assemblies 4234. The light guide cavity 4233 can be provided with a fixing member 4233c. The first mounting plate 4232 can be connected to the fixing member 4233c through the plurality of first angle adjusting assemblies 4234. The plurality of first angle adjusting assemblies 4234 can cooperate to adjust the angle of the first mounting plate 4232 relative to the fixing base 4231. Specifically, the fixing member 4233c can be in the shape of a plate, and the plate-shaped fixing member 4233c can be arranged in parallel with the first mounting plate 4232. The number of the fixing member 4233c can correspond to the number of the first angle adjusting assemblies 4234 to ensure the firmness of the connection of the first mounting plate 4232. Since the material is cut by the first light beam emitted by the laser source assembly 20, the volume of the cut material changes, and the position irradiated by the second light beam also needs to change accordingly. The plurality of first angle adjusting assemblies 4234 can be rotated towards or away from the fixing base 4231, so that the part of the first mounting plate 4232 connected to the first angle adjusting assembly 4234 moves towards the fixing base 4231, thereby driving the second reflecting member 422 to rotate correspondingly, and then the second light beam can be reflected along the target angle and transmitted to the shooting light path 111 through the second part 4233b of the light guide cavity 4233, thereby ensuring the brightness of the material and improving the real-time shooting effect of the camera 110. The number of the first angle adjusting assemblies 4234 can be determined according to actual needs, and the number of the first angle adjusting assemblies 4234 can be increased to achieve more accurate angle adjustment. The number of the first angle adjusting assemblies 4234 is not limited in the present application. In this way, the plurality of first angle adjusting assemblies 4234 can firmly fix the first mounting plate 4232 on the fixing member 4233c, and through the cooperation of the plurality of first angle adjusting assemblies 4234, the angle of the first mounting plate 4232 relative to the fixing base 4231 can be adjusted, thereby adjusting the reflection angle of the second light beam, effectively simplifying the operation steps of the second reflection adjusting assembly 423, and improving the convenience and practicality of the use of the second reflection adjusting assembly 423.

[0063] In combination with reference to Figure 1 , Figure 4 , Figure 7 and Figure 8The first angle adjusting assembly 4234 can include a positioning member 4234a and an angle adjusting member 4234b. The positioning member 4234a and the angle adjusting member 4234b can be connected to the corresponding fixing member 4233c through the first mounting plate 4232. The angle adjusting member 4234b can be used to rotate and adjust the distance between the first mounting plate 4232 and the fixing member 4233c. The positioning member 4234a can be used to limit the displacement of the first mounting plate 4232 after the adjustment of the angle adjusting member 4234b. Specifically, the positioning member 4234a and the angle adjusting member 4234b can be arranged one by one. By rotating the angle adjusting member 4234b, the distance between the first mounting plate 4232 and the fixing member 4233c can be adjusted, so that the angle of the second reflecting member 422 relative to the fixed seat 4231 can be adjusted. After the adjustment is completed, the positioning member 4234a can be rotated to limit the first mounting plate 4232 to the current position, so that the position of the first mounting plate 4232 does not deviate when the photographing device 1 is used, the target angle of the second reflecting member 422 relative to the fixed seat 4231 is deviated, and the situation that the second light beam cannot reach the photographing light path 111 occurs. The fixing member 4233c can be provided with a connecting hole matched with the positioning member 4234a. The positioning member 4234a is connected to the connecting hole in a detachable manner, for example, threaded connection, etc. In this way, by cooperating and adjusting the positioning member 4234a and the angle adjusting member 4234b, the first mounting plate 4232 can be locked in the adjusted position after being adjusted to the appropriate position, so that the situation that the adjustment fails due to the loosening of the first mounting plate 4232 is avoided, and the reliability and practicability of the first angle adjusting assembly 4234 are effectively improved.

[0064] With reference to Figure 7 and Figure 8 One end of the angle adjusting member 4234b can abut against the corresponding fixing member 4233c, and the other end of the angle adjusting member 4234b can be rotatably connected to the first mounting plate 4232. The angle adjusting member 4234b can be used to rotate and drive the first mounting plate 4232 to move towards or away from the fixing member 4233c. During the rotation of the angle adjusting member 4234b, one end of the angle adjusting member 4234b can always abut against the fixing member 4233c, so that a stable connection relationship is formed between the angle adjusting member 4234b and the fixing member 4233c, and the first mounting plate 4232 is driven by the other end of the angle adjusting member 4234b to move towards or away from the fixing member 4233c, thereby effectively improving the adjustment efficiency and stability of the angle adjusting member 4234b.

[0065] In some embodiments, with reference to Figure 4 and Figure 7The first angle adjustment assembly 4234 is arranged along the edge of the first mounting plate 4232. Specifically, the number of the first angle adjustment assembly 4234 can be four, and the four first angle adjustment assemblies 4234 are arranged at the four vertices of the first mounting plate 4232. The reflection angle of the second reflecting member 422 can be quickly adjusted by adjusting the positions of the four vertices of the first mounting plate 4232. In this way, the first mounting plate 4232 can be precisely adjusted, thereby improving the adjustment accuracy and precision of the second reflecting member 422, and effectively ensuring the reflection effect of the second reflecting member 422.

[0066] In some embodiments, in combination with the description of Figure 1 , Figure 4 and Figure 6 , the fixed seat 4231 has a light beam inlet 4231a in communication with the light guide cavity 4233, and the second path 411 extends through the light beam inlet 4231a to the first part 4233a. The light beam inlet 4231a is formed on the side of the fixed seat 4231 facing the light emitting member 410, and the light emitting member 410 can be arranged close to the light beam inlet 4231a. The size of the light beam inlet 4231a can be greater than the diameter of the light emitting member 410, so as to guide all the second light beams emitted by the light emitting member 410 into the fixed seat 4231, thereby avoiding the loss of light energy of the light emitting member 410. In this way, while ensuring the transmission effect of the second light beams emitted by the light emitting member 410, the mechanical structure of the photographing device 1 can be simplified, and the photographing device 1 can be miniaturized and precisionized.

[0067] In some embodiments, in combination with the description of Figure 1 , Figure 4 and Figure 6 , the fixed seat 4231 has a light beam outlet 4231b in communication with the light guide cavity 4233, and the second light beams reflected by the second reflecting member 422 extend through the light beam outlet 4231b to the second part 4233b. Specifically, the light beam outlet 4231b is formed on the side of the fixed seat 4231 facing the camera 110, and the camera 110 can be arranged close to the light beam outlet 4231b. The size of the light beam outlet 4231b can be less than the diameter of the camera 110, so as to transmit all the second light beams reflected by the second reflecting member 422 to the photographing light path 111 of the camera 110, thereby effectively improving the photographing effect of the camera 110. The plane on which the light beam inlet 4231a is located and the plane on which the light beam outlet 4231b is located can be perpendicular to each other, so that the second light beams entering through the light beam inlet 4231a can be directly emitted out of the light beam outlet 4231b under the action of the second reflecting member 422, thereby reducing the volume of the fixed seat 4231 and the operation space required to be occupied. In this way, while ensuring the transmission effect of the second light beams emitted by the light emitting member 410 and the photographing effect of the camera 110, the mechanical structure of the photographing device 1 can be further simplified, and the photographing device 1 can be miniaturized and precisionized.

[0068] With reference to Figure 1 , Figure 2 and Figure 10 , the first reflecting member 30 can be connected with a first reflecting adjusting assembly 50. The first reflecting adjusting assembly 50 can include a fixed plate 510, a second mounting plate 520 and a second angle adjusting assembly. The first reflecting member 30 can be arranged on the second mounting plate 520. The second angle adjusting assembly can include at least one of a first adjusting assembly 531, a second adjusting assembly 532 and a third adjusting assembly 533. Wherein, the first adjusting assembly 531 can be configured to adjust the angle of the second mounting plate 520 relative to the fixed plate 510 along a third direction (such as the X-X direction in Figure 9 ). The second adjusting assembly 532 can be configured to adjust the angle of the second mounting plate 520 relative to the fixed plate 510 along a fourth direction (such as the Y-Y direction in Figure 9 ). The third adjusting assembly 533 can be configured to adjust the angle of the second mounting plate 520 relative to the fixed plate 510 along a fifth direction (such as the Z-Z direction in Figure 9 ). The first reflecting member 30 is arranged on the second mounting plate 520, so adjusting the angle of the second mounting plate 520 relative to the fixed plate 510 is to adjust the angle of the first reflecting member 30 relative to the fixed plate 510. The first reflecting member 30 can be fixed on the second mounting plate 520 by pasting. Of course, it is not excluded that the first reflecting member 30 can be fixed on the second mounting plate 520 by other connecting methods. In addition, the third direction, the fourth direction and the fifth direction are three different directions. The third direction, the fourth direction and the fifth direction can be perpendicular to each other. Of course, the third direction, the fourth direction and the fifth direction can also have other angles between each other. In this way, the second angle adjusting assembly includes at least one of the first adjusting assembly 531, the second adjusting assembly 532 and the third adjusting assembly 533, and the angle of the first reflecting member 30 in one direction is adjusted by one adjusting assembly, so as to improve the accuracy of angle adjustment and avoid the first reflecting member 30 deviating from the target direction and the target angle to be adjusted by a large margin.

[0069] Specifically, the fixed plate 510 is provided with a hollow light passing hole 511 corresponding to the position of the first reflecting member 30, which ensures that the first light beam emitted by the laser source assembly 20 can pass through the first reflecting member 30 along the first path 310 to reach the material.

[0070] Preferably, the second angle adjusting assembly can include a first adjusting assembly 531, a second adjusting assembly 532 and a third adjusting assembly 533. The number of the first adjusting assembly 531, the second adjusting assembly 532 and the third adjusting assembly 533 can be one. The line connecting the first adjusting assembly 531, the second adjusting assembly 532 and the third adjusting assembly 533 projected on the second mounting plate 520 can be a triangle. Specifically, the first adjusting assembly 531, the second adjusting assembly 532 and the third adjusting assembly 533 can be arranged at three corners of the fixed plate 510 or the second mounting plate 520. In this way, by adjusting the angle of one direction of the first reflecting member 30 through each adjusting assembly, the accuracy of angle adjustment is improved, and the purpose of accurately adjusting the direction of the second light beam is achieved.

[0071] In some embodiments, the second angle adjusting assembly can further include multiple cases, for example, the case where the second angle adjusting assembly includes the first adjusting assembly 531 (as shown in Figure 1 and Figure 2 ), the case where the second angle adjusting assembly further includes the second adjusting assembly 532, and so on. According to different application scenarios, the corresponding second angle adjusting assembly can be arranged, thereby saving the cost.

[0072] Referring to Figures 9 to 11 , the first adjusting assembly 531 can include a first adjusting member 5311, a first mounting hole 5312 arranged on the second mounting plate 520 and a V-shaped groove 5313 (i.e. a long tapered groove) arranged on the fixed plate 510. The first adjusting member 5311 rotatably abuts against the V-shaped groove 5313 through the first mounting hole 5312. In this way, the first adjusting assembly 531 can accurately adjust the angle of the first reflecting member 30 in the third direction, avoiding the case where the first reflecting member 30 deviates greatly from the target direction and the target angle to be adjusted. The first adjusting member 5311 can be a screw or a bolt, etc. The first mounting hole 5312 can be a threaded hole or a through hole, etc. Preferably, one end of the first adjusting member 5311 abutting against the V-shaped groove 5313 can be a spherical structure, so as to facilitate the movement of the first adjusting member 5311 in the V-shaped groove 5313 along the third direction, thereby achieving the angle adjustment of the first reflecting member 30 along the third direction. Of course, it is not excluded that one end of the first adjusting member 5311 abutting against the V-shaped groove 5313 can be a hemispherical structure, etc. In some embodiments, by rotatably abutting the first adjusting member 5311 against the V-shaped groove 5313, the pitch angle of the first reflecting member 30 can be accurately adjusted.

[0073] Specifically, the first sleeve 5314 can be arranged in the first mounting hole 5312. The first sleeve 5314 can be threadedly connected with the first adjusting piece 5311. The first adjusting piece 5311 is connected with the first mounting hole 5312 through the first sleeve 5314, so that the second mounting plate 520 is prevented from being damaged, and cost is saved.

[0074] Further, the first sleeve 5314 can be provided with the first locking nut 5315 above. The first locking nut 5315 can be threadedly connected with the first adjusting piece 5311. The stability of the connection between the first adjusting piece 5311 and the second mounting plate 520 is further improved, so that the first adjusting piece 5311 is prevented from being loosened relative to the second mounting plate 520 when the angle of the second mounting plate 520 relative to the fixed plate 510 is adjusted.

[0075] With reference to Figure 11 and Figure 13 , the V-shaped groove 5313 can be provided with the plate-shaped piece 5313b on the groove side wall 5313a. The first adjusting piece 5311 can be rotatably abutted against the plate-shaped piece 5313b. Specifically, the fixed plate 510 can be made of aluminum which has a relatively light material and a relatively low hardness. Therefore, the plate-shaped piece 5313b made of stainless steel can be arranged on the groove side wall 5313a of the V-shaped groove 5313 to ensure the hardness. The plate-shaped piece 5313b can be square-shaped, which can be conveniently combined with the groove side wall 5313a of the V-shaped groove 5313 and is easy to process and manufacture. The number of the plate-shaped piece 5313b can be two, and the two plate-shaped pieces 5313b can be respectively arranged on the two oppositely arranged long strip-shaped groove side walls 5313a. The shape and number of the plate-shaped piece 5313b are not limited in the application. In some embodiments, the first adjusting piece 5311 can sequentially pass through the first locking nut 5315, the first sleeve 5314 in the first mounting hole 5312, and can be rotatably abutted against the plate-shaped piece 5313b. In this way, the groove side wall 5313a of the V-shaped groove 5313 is spaced apart from the first adjusting piece 5311 through the plate-shaped piece 5313b, so that the direct contact between the groove side wall 5313a of the V-shaped groove 5313 and the first adjusting piece 5311 is avoided, and the groove side wall 5313a of the V-shaped groove 5313 is prevented from being damaged or deformed due to the abutment of the first adjusting piece 5311.

[0076] With reference to Figure 9 , Figure 10 and Figure 14The first adjusting assembly 531 can further include a first elastic member 5316. One end of the first elastic member 5316 can be connected to the fixed plate 510, and the other end of the first elastic member 5316 can be connected to the second mounting plate 520. It should be noted that the force generated by the first elastic member 5316 on the fixed plate 510 and the second mounting plate 520 is opposite to the force generated by the first adjusting member 5311 on the fixed plate 510 and the second mounting plate 520. Specifically, the first elastic member 5316 can be a spring or the like. In this way, by providing the first elastic member 5316, the accuracy of the first adjusting assembly 531 adjusting the angle of the first reflecting member 30 in the third direction is further increased.

[0077] Further, the first elastic member 5316 can have a first elastic portion, a first fixed portion, and a second fixed portion. Specifically, the first fixed portion and the second fixed portion can both be positioning pins. The fixed plate 510 can have a first fixed hole 512, and the second mounting plate 520 can have a second fixed hole 521. The first fixed portion is inserted into the first fixed hole 512, and the second fixed portion is inserted into the second fixed hole 521. The two ends of the first elastic member 5316 can be hooks, which can be hung on the first fixed portion and the second fixed portion respectively. This ensures the stability of the connection between the first elastic member 5316 and the fixed plate 510 and the second mounting plate 520, and facilitates installation or disassembly.

[0078] In combination with reference to Figure 9 , Figure 10 and Figure 12 , the second adjusting assembly 532 can include a second adjusting member 5321, a second mounting hole 5322 provided on the second mounting plate 520, and a tapered groove 5323 provided on the fixed plate 510. The second adjusting member 5321 passes through the second mounting hole 5322 and abuts against the tapered groove 5323 rotatably. In this way, the second adjusting assembly 532 can accurately adjust the angle of the first reflecting member 30 in the fourth direction, avoiding the first reflecting member 30 from having a large deviation from the target direction and the target angle to be adjusted. The second adjusting member 5321 can be a screw or a bolt or the like. The second mounting hole 5322 can be a threaded hole or a through hole or the like. Preferably, one end of the second adjusting member 5321 abutting against the tapered groove 5323 can be a spherical structure, so as to facilitate the movement of the second adjusting member 5321 in the tapered groove 5323 in the fourth direction, thereby achieving the angle adjustment of the first reflecting member 30 in the fourth direction. Of course, it is not excluded that one end of the second adjusting member 5321 abutting against the tapered groove 5323 can be a hemispherical structure or the like. In some embodiments, by the second adjusting member 5321 rotatably abutting against the tapered groove 5323, the height of the first reflecting member 30 (i.e., the distance between the second mounting plate 520 and the fixed plate 510) can be accurately adjusted.

[0079] Specifically, a second sleeve 5324 can be arranged in the second mounting hole 5322. The second sleeve 5324 can be threadedly connected with the second adjusting member 5321. The second adjusting member 5321 is connected with the second mounting hole 5322 through the second sleeve 5324, so that the second mounting plate 520 is prevented from being damaged, and cost is saved.

[0080] With reference to Figures 9 to 14 The second adjusting assembly 532 can further include a second elastic member 5325. One end of the second elastic member 5325 can be connected to the fixed plate 510, and the other end of the second elastic member 5325 can be connected to the second mounting plate 520. It should be noted that the force generated by the second elastic member 5325 on the fixed plate 510 and the second mounting plate 520 is opposite to the force generated by the second adjusting member 5321 on the fixed plate 510 and the second mounting plate 520. Specifically, the second elastic member 5325 can be a spring or the like. In this way, by arranging the second elastic member 5325, the accuracy of the second adjusting assembly 532 in adjusting the angle of the first reflecting member 30 in the fourth direction is further improved.

[0081] Further, the second elastic member 5325 can have a second elastic portion, a third fixed portion and a fourth fixed portion. Specifically, the third fixed portion and the fourth fixed portion can both be positioning pins. The fixed plate 510 can have a third fixed hole 513, and the second mounting plate 520 can have a fourth fixed hole 522. The third fixed portion is arranged in the third fixed hole 513, and the fourth fixed portion is arranged in the fourth fixed hole 522. The two ends of the second elastic member 5325 can be hooks, and the two ends can be hung on the third fixed portion and the fourth fixed portion respectively. The stability of the connection between the second elastic member 5325 and the fixed plate 510 and the second mounting plate 520 is ensured, and the installation or disassembly is facilitated.

[0082] Again with reference to Figures 9 to 11The third adjusting assembly 533 can include a third adjusting piece 5331, a third mounting hole 5332 arranged on the second mounting plate 520, and a flat-bottom groove 5333 arranged on the fixing plate 510. The third adjusting piece 5331 can be rotatably abutted against the flat-bottom groove 5333 through the third mounting hole 5332. In this way, the third adjusting assembly 533 can accurately adjust the angle of the first reflecting piece 30 in the fifth direction, avoiding the first reflecting piece 30 deviating from the target direction and the target angle to be adjusted by a large margin. Preferably, one end of the third adjusting piece 5331 abutting against the flat-bottom groove 5333 can be a spherical structure, so as to facilitate the movement of the third adjusting piece 5331 in the flat-bottom groove 5333 in the fifth direction, thereby realizing the angle adjustment of the first reflecting piece 30 in the fifth direction. Of course, it is not excluded that the one end of the third adjusting piece 5331 abutting against the flat-bottom groove 5333 can be a hemispherical structure, etc. In some embodiments, the third adjusting piece 5331 is rotatably abutted against the flat-bottom groove 5333, thereby accurately adjusting the left-right inclination angle of the first reflecting piece 30.

[0083] Specifically, the third mounting hole 5332 can be provided with a third sleeve 5334. The third sleeve 5334 can be threadedly connected with the third adjusting piece 5331. The third adjusting piece 5331 and the third mounting hole 5332 are connected through the third sleeve 5334, avoiding the damage of the second mounting plate 520 and saving the cost.

[0084] Further, the third sleeve 5334 can be provided with a second locking nut 5335 above. The second locking nut 5335 can be threadedly connected with the third adjusting piece 5331. The stability of the connection between the third adjusting piece 5331 and the second mounting plate 520 is further improved, avoiding the phenomenon that the third adjusting piece 5331 is loosened relative to the second mounting plate 520 when adjusting the angle of the second mounting plate 520 relative to the fixing plate 510.

[0085] Again, refer to Figure 11 and Figure 13The bottom wall 5333a of the flat groove 5333 can be provided with a pad 5333b, and the third adjusting member 5331 can rotatably abut against the pad 5333b. Specifically, the fixed plate 510 can be made of aluminum which is light in weight but low in hardness. Therefore, the pad 5333b made of stainless steel can be arranged on the bottom wall 5333a of the flat groove 5333 to ensure the hardness. The pad 5333b can be in the shape of a round cake, which can not only facilitate the combination with the bottom wall 5333a of the flat groove 5333, but also be easy to process and manufacture. In some embodiments, the third adjusting member 5331 can pass through the second locking nut 5335, the third sleeve 5334 in the third mounting hole 5332 in sequence, and rotatably abut against the pad 5333b.
