DETAILED DESCRIPTION

[0040] In the following description, a large amount of details are provided so that the present invention can be thoroughly understood. However, it will be appreciated by those skilled in the art that the following description only exemplarily illustrates a preferred embodiment of the present invention, and the present invention can be implemented without one or more such details. In addition, in order to avoid confusion with the present invention, some technical features well known in the art are not described in detail.

[0041] In order to fully understand the embodiments of the present invention, detailed structures will be presented in the following description. Obviously, the implementation of the embodiments of the present invention is not limited to the specific details familiar to those skilled in the art. The preferred embodiments of the present invention are described in detail below, but in addition to these detailed descriptions, the present invention may also have other embodiments.

[0042] An embodiment of the present invention provides a photographing device. The photographing device provided by the present invention can be applied to laser processing equipment. The following will introduce a photographing device according to an embodiment of the present invention in detail in conjunction with the accompanying drawings.

[0043] Combined with reference Figures 1 to 4 , the shooting device 1 may include a camera assembly 10, a laser source assembly 20, and a first reflector 30. The camera assembly 10 may have a shooting optical path 111 for shooting a material. The laser source assembly 20 may be used to emit a first light beam. The first light beam may be a laser or the like. The first reflector 30 may be arranged on the shooting optical path 111. The first reflector 30 and the shooting optical path 111 have an angle, for example, an angle of 45 degrees. The first light beam may reach the material along the first path 310 after being reflected by the first reflector 30. It should be noted that the first reflector 30 may be an optical lens, such as a reflector or the like. The shooting optical path 111 may be coaxial with the first path 310. Among them, the camera assembly 10 may include a camera 110, a first optical path assembly 120, and a camera adjustment assembly 130. The camera adjustment assembly 130 and the first optical path assembly 120 may be arranged sequentially along the shooting optical path 111. The camera 110 may be connected to a side of the camera adjustment assembly 130 away from the first optical path assembly 120. An active gap 140 may be formed between the outer wall of the first optical path component 120 and the inner wall of the camera adjustment component 130. The relative position relationship between the camera 110 and the first optical path component 120 may be adjusted by changing the size of the active gap 140.

[0044] The camera 110 can photograph the material, and the photographing light path 111 of the camera 110 can pass through the first light path component 120 to reach the material. The first light path component 120 and the material can have a relatively fixed positional relationship to obtain an image of the material.

[0045] The side of the camera adjustment component 130 away from the camera 110 can be mounted on the outside of the first optical path component 120, so that a movable gap 140 is formed between the inner wall of the camera adjustment component 130 and the outer wall of the first optical path component 120. When the camera component 10 is arranged in the vertical direction, the movable gap 140 can make the camera adjustment component 130 have a certain degree of freedom in the horizontal direction relative to the first optical path component 120, and then the relative position relationship between the camera 110 connected to the camera adjustment component 130 and the first optical path component 120 can be adjusted, thereby ensuring the shooting effect of the camera 110.

[0046] The material can be a wafer, specifically a silicon wafer used for the production of silicon semiconductor integrated circuits, and its shape can be round. Various circuit element structures can be processed on the silicon wafer to become a product with specific electrical functions. Wafers are fragile and easy to scratch, especially ultra-thin wafer processing, which has high requirements for thermal effects. The laser source assembly 20 can emit a first light beam, which is reflected by the first reflector 30 and reaches the wafer along the first path 310, and finally focuses on the inside of the wafer cutting path. The energy focusing generates high temperature, which can realize invisible wafer cutting, that is, explosion points are generated inside the wafer cutting path, and cracks are generated by connecting multiple points, so that the wafer chips are separated to achieve the cutting purpose. During the processing, no dust is generated, and the wafer will not be contaminated. It belongs to non-contact processing, and the thermal impact is very small. It is very effective for processing thinner wafers.

[0047] In some other embodiments, an active gap 140 for adjusting the relative position relationship between the camera 110 and the first optical path component 120 may be formed between the inner wall of the first optical path component 120 and the outer wall of the camera adjustment component 130, and the present application does not make any specific limitation on this.

[0048] In the photographing device 1 of the present invention, on the one hand, an active gap 140 can be formed between the outer wall of the first optical path component 120 and the inner wall of the camera adjustment component 130. By adjusting the above-mentioned active gap 140, a relative displacement can be generated between the camera 110 connected to the camera adjustment component 130 and the first optical path component 120, thereby realizing the distance adjustment between the camera 110 and the material, effectively simplifying the mechanical structure of the photographing device 1, reducing the operating space required for the photographing device 1, realizing the precision and miniaturization of the photographing device 1, and also reducing the manufacturing cost of the photographing device 1, and improving the convenience of use for the operator. On the other hand, when the photographing device 1 of the present invention is applied to a laser processing component, since the shooting optical path 111 is coaxial with the first path 310, the camera component 10 can be used to shoot the material in real time to improve the accuracy of the laser processing material, thereby improving the processing quality and avoiding the waste caused by poor processing.

[0049] Combined with reference Figure 3 and Figure 4, the camera adjustment component 130 may include a first camera adjustment member 131 and a second camera adjustment member 132. The first camera adjustment member 131 and the second camera adjustment member 132 may be connected. The first camera adjustment member 131 and the second camera adjustment member 132 are detachably connected, and the detachable connection includes a plug connection or a threaded connection, etc., which is not specifically limited in this application. The first optical path component 120 and the first camera adjustment member 131 can be movably connected to form a movable gap 140 between the two. The second camera adjustment member 132 can be connected to the camera 110. The relative position relationship between the camera 110 and the first optical path component 120 can be further adjusted by the first camera adjustment member 131 and the second camera adjustment member 132, which not only improves the shooting effect of the camera 110, but also simplifies the mechanical structure of the camera adjustment component 130 and reduces the operating space required for the camera adjustment component 130.

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

[0051] Furthermore, the number of the first position-limiting members 1311 may be multiple, and the multiple first position-limiting members 1311 may be arranged at intervals along the outer periphery of the first optical path component 120. Preferably, the number of the first position-limiting members 1311 may be three, and the angle formed between every two first position-limiting members 1311 may be 120 degrees. The relative position relationship between the camera 110 and the first optical path component 120 may be accurately adjusted through the three first position-limiting members 1311. Through the cooperation between the multiple first position-limiting members 1311, not only the relative position relationship between the camera 110 and the first optical path component 120 may be accurately adjusted, but also a firm connection relationship may be formed between the camera 110 and the first optical path component 120, thereby avoiding the occurrence of positional displacement during use, and effectively improving the practicality and reliability of the camera adjustment component 130.

[0052] See also Figure 4 The second camera adjustment member 132 may have a first connection end and a second connection end. The first connection end may be rotatably connected to the first camera adjustment member 131. The second connection end may be connected to the camera 110. The second camera adjustment member 132 may be used to drive the camera 110 along a first direction (such as Figure 4 PP direction) and along a second direction (such as Figure 4 The first direction may be represented as a clockwise or counterclockwise direction, and the second direction may be represented as a direction away from or close to the first optical path component 120.

[0053] Optionally, the side of the second camera adjustment member 132 away from the camera 110 can be sleeved outside the first camera adjustment member 131 and threadedly connected to the first camera adjustment member 131. Specifically, an outer wall of the first camera adjustment member 131 can be formed with an outer thread, and an inner wall of the side of the second camera adjustment member 132 away from the camera 110 can be formed with an inner thread matched with the outer thread. When the second camera adjustment member 132 is rotated, the second camera adjustment member 132 can drive the camera 110 to rotate in a clockwise direction or a counterclockwise direction, and can also drive the camera 110 to rotate in a direction away from or close to the first optical path component 120.

[0054] Optionally, the side of the second camera adjustment component 132 away from the camera 110 can be mounted on the outside of the first camera adjustment component 131 and can be plugged and unplugged with the first camera adjustment component 131. Specifically, the outer wall of the first camera adjustment component 131 and the inner wall of the second camera adjustment component 132 away from the camera 110 can be abutted against each other, and the camera 110 can be rotated in a clockwise or counterclockwise direction, and in a direction away from or close to the first optical path component 120 by plugging and rotating the second camera adjustment component 132.

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

[0056] Again, refer to Figure 4 and Figure 5 , the camera assembly 10 may further include a fixing portion 150 rotatably connected to the outer wall of the first camera adjustment member 131. The fixing portion 150 may have an upper end surface 151. When the second camera adjustment member 132 rotates a preset angle, the fixing portion 150 may rotate so that the upper end surface 151 abuts against the first connection end. Specifically, the fixing portion 150 may be in the shape of an annular ring, and the annular fixing portion 150 may be sleeved on the outer wall of the first camera adjustment member 131, and the position of the fixing portion 150 is closer to the first optical path assembly 120 than the second camera adjustment member 132. An external thread may be formed on the outer wall of the first camera adjustment member 131, and an internal thread compatible with the external thread may be formed on the inner wall of the fixing portion 150, and the fixing portion 150 may be rotatably connected to the outer wall of the first camera adjustment member 131. In this way, the second camera adjustment member 132 and the camera 110 are confined to the desired position, avoiding the position displacement of the second camera adjustment member 132 and the camera 110 during use, effectively improving the firmness of the connection between the second camera adjustment member 132 and the first camera adjustment member 131, and further improving the overall firmness of the camera adjustment assembly 130.

[0057] Again, refer to Figure 4 and Figure 5, the fixing part 150 may include a second stopper 152 and a second sleeve 153. The second sleeve 153 may be rotatably connected to the outer wall of the first camera adjustment member 131. The second stopper 152 may be inserted through the second sleeve 153 and abut against the outer wall of the first camera adjustment member 131. Specifically, a second through hole may be provided on the side wall of the second sleeve 153, and the second stopper 152 may pass through the second through hole and abut against the outer wall of the first camera adjustment member 131, thereby firmly fixing the fixing part 150 to the outer wall of the first camera adjustment member 131. The second stopper 152 may specifically be a fastener, such as a screw or a bolt, etc., and rotating the second stopper 152 clockwise may connect the second sleeve 153 to the first camera adjustment member 131, and vice versa, rotating the second stopper 152 counterclockwise may disengage the second sleeve 153 from the first camera adjustment member 131. In this way, the second limit member 152 can firmly fix the second sleeve 153 on the outer wall of the first camera adjustment member 131, thereby preventing the second camera adjustment member 132 and the camera 110 from being displaced when subjected to external force, and further improving the overall firmness of the camera adjustment assembly 130.

[0058] In some embodiments, a step portion 121 may be formed at one end of the first optical path component 120 close to the first camera adjustment member 131, and the first camera adjustment member 131 may be located on the step portion 121. In this way, sufficient support force can be provided to the camera adjustment component 130 and the camera 110, which can not only ensure the stability of the camera adjustment component 130 during the adjustment process, but also enable the camera 110 to have a more stable shooting condition, effectively improving the shooting effect of the camera 110, as well as the practicality and reliability of the camera adjustment component 130.

[0059] Again, refer to Figures 1 to 4, a light source assembly 40 may be provided beside the camera 110. The light source assembly 40 may include a light emitting element 410 and a second optical path assembly 420. The light emitting element 410 may be used to emit a second light beam along a second path 411. The second light beam may be monochromatic light, mixed light, etc. The second optical path assembly 420 may have a second reflector 422 and a second reflection adjustment assembly 423. It should be noted that the second reflector 422 may be an optical lens, such as a reflector, etc. The second reflector 422 may be provided on the second path 411 to reflect the second light beam. The second reflection adjustment assembly 423 may be connected to the second reflector 422 to adjust the reflection angle of the second light beam so that the second light beam may be transmitted to the shooting optical path 111 along the third path 421. Specifically, the light emitting element 410 may emit a second light beam to the material to make the material brighter. The light emitting element 410 may be an LED lamp or a laser emitter, etc. The present application does not specifically limit the type of the light emitting element 410, and the user may determine the type of the light emitting element 410 according to actual use needs. A convex lens 430, an adjustable aperture 440 and an achromatic lens 450 may be sequentially arranged on the second path 411 of the light emitting element 410, and the second light beam emitted by the light emitting element 410 may be sequentially projected into the second reflector 422 through the convex lens 430, the adjustable aperture 440 and the achromatic lens 450. The convex lens 430 may focus the light beam emitted by the light emitting element 410, and the adjustable aperture 440 may adjust the amount of light entering, thereby controlling the exposure effect of the camera 110. The achromatic lens 450 may be used to correct the refraction difference of light beams of different wavelengths, reduce chromatic aberration, and ensure the color accuracy and clarity of the image captured by the camera 110. Through the combined action of the above devices, the camera 110 can capture high-quality images. The second reflector 422 may receive the second light beam and reflect it outward at a certain angle. The second reflector 422 may be a plane mirror, etc., which is not specifically limited in the present application. When the second reflection adjustment component 423 is adjusted, the second reflection member 422 can be driven to deflect synchronously, thereby adjusting the reflection angle of the second light beam through the second reflection member 422, and then the second light beam can be transmitted to the shooting light path 111 with a better angle and effect. A refractor 460 can be provided at the intersection of the third path 421 and the shooting light path 111, and the second light beam reflected by the second reflection member 422 can be refracted by the refractor 460 to be coaxial with the shooting light path 111 to irradiate the material. In this way, when the light emitting member 410 emits the second light beam to the second reflection member 422, the second reflection adjustment component 423 can continuously adjust the reflection angle of the second reflection member 422, so that the second light beam emitted by the light emitting member 410 can be merged into the shooting light path 111 of the camera 110, thereby realizing the lighting needs of the camera 110, effectively simplifying the mechanical structure of the shooting device 1, reducing the operating space required by the shooting device 1, realizing the precision and miniaturization of the shooting device 1, and also improving the convenience of the operator.

[0060] Combined with reference Figure 3 , Figure 4 and Figure 7 , the second reflection adjustment component 423 may include a fixing seat 4231 and a first mounting plate 4232. The second reflector 422 may be disposed on the first mounting plate 4232. The first mounting plate 4232 and the fixing seat 4231 may be movably connected to adjust the reflection angle of the second light beam. Specifically, the fixing seat 4231 may be connected to the light emitting element 410 and the camera 110 respectively, and the second reflector 422 may be connected to the fixing seat 4231 through the first mounting plate 4232. The second reflector 422 and the first mounting plate 4232 may be detachably connected or integrally formed, and the detachable connection may include a snap connection or an adhesive connection, etc., which is not specifically limited in the present application. The first mounting plate 4232 may have a groove adapted to the second reflector 422 on one side facing the fixing seat 4231, and the second reflector 422 may be snapped into the groove, so that a stable connection is formed between the second reflector 422 and the first mounting plate 4232. In this way, while adjusting the reflection angle of the second light beam, the mechanical structure of the second reflection adjustment component 423 is simplified, and the difficulty of manufacturing the second reflection adjustment component 423 is reduced.

[0061] Combined with reference Figure 4 , Figure 6 and Figure 7 , the fixing seat 4231 and the first mounting plate 4232 may enclose a light guide cavity 4233. The second reflector 422 may be located in the light guide cavity 4233, and the light guide cavity 4233 may 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 reflector 422 may have a reflective surface, and the reflective surface of the second reflector 422 may be located in the light guide cavity 4233. The second light beam emitted by the light emitting element 410 is incident on the second reflector 422 through the first portion 4233a of the light guide cavity 4233, and the second light beam reflected by the second reflector 422 may be transmitted to the shooting light path 111 through the second portion 4233b of the light guide cavity 4233. In this way, a path for light beam transmission can be formed through the cooperation of the fixed seat 4231 and the first mounting plate 4232, and the second reflector 422 can be located at the intersection of the first part 4233a and the second part 4233b, thereby effectively reducing the volume occupied by the second reflection adjustment component 423 and improving the rationality of the layout of the second reflection adjustment component 423.

[0062] Combined with adoption Figure 1 , Figure 3 , Figure 7 and Figure 8, the second reflection adjustment component 423 may include a plurality of first angle adjustment components 4234. A fixing member 4233c may be provided in the light guide cavity 4233. The first mounting plate 4232 may be connected to the fixing member 4233c through a plurality of first angle adjustment components 4234. The plurality of first angle adjustment components 4234 may cooperate to adjust the angle of the first mounting plate 4232 relative to the fixing seat 4231. Specifically, the fixing member 4233c may be in the shape of a plate, and the setting direction of the plate-shaped fixing member 4233c may be parallel to the setting direction of the first mounting plate 4232. The number of fixing members 4233c may correspond to the number of first angle adjustment components 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 of the second light beam irradiation needs to change accordingly. The multiple first angle adjustment assemblies 4234 can be rotated in the direction close to or away from the fixed seat 4231, so that the part of the first mounting plate 4232 connected to the first angle adjustment assembly 4234 moves in the direction close to the fixed seat 4231, thereby driving the corresponding rotation of the second reflector 422, so that 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 first angle adjustment assemblies 4234 can be determined according to actual use needs, and the number of first angle adjustment assemblies 4234 can be increased to achieve more precise angle adjustment. The present application does not specifically limit the number of first angle adjustment assemblies 4234. In this way, multiple first angle adjustment components 4234 can firmly fix the first mounting plate 4232 on the fixing member 4233c, and through the mutual cooperation of multiple first angle adjustment components 4234, the angle of the first mounting plate 4232 relative to the fixing seat 4231 can be adjusted, thereby realizing the adjustment of the reflection angle of the second light beam, effectively simplifying the operation steps of the second reflection adjustment component 423, and improving the convenience and practicality of using the second reflection adjustment component 423.

[0063] Combined with reference Figure 1 , Figure 4 , Figure 7 and Figure 8, the first angle adjustment assembly 4234 may include a positioning member 4234a and an angle adjustment member 4234b. The positioning member 4234a and the angle adjustment member 4234b may respectively pass through the first mounting plate 4232 and be connected to the corresponding fixing member 4233c. The angle adjustment member 4234b may be used to rotate and adjust the distance between the first mounting plate 4232 and the fixing member 4233c. The positioning member 4234a may be used to limit the displacement of the first mounting plate 4232 after the angle adjustment member 4234b is adjusted. Specifically, the positioning member 4234a and the angle adjustment member 4234b can be arranged in a one-to-one correspondence. By rotating the angle adjustment member 4234b, the distance between the first mounting plate 4232 and the fixing member 4233c can be adjusted, thereby adjusting the angle of the second reflective member 422 relative to the fixing seat 4231. After the adjustment is completed, the positioning member 4234a can be rotated to limit the first mounting plate 4232 to the current position, so as to avoid the position of the first mounting plate 4232 from being offset when the shooting device 1 is used, so that the second reflective member 422 has a deviation from the target angle to which the fixing seat 4231 needs to be adjusted, resulting in the second light beam failing to reach the shooting optical path 111. The fixing member 4233c can be provided with a connection hole adapted to the positioning member 4234a, and the positioning member 4234a is connected to the connection hole in a detachable connection manner, such as a threaded connection. In this way, through the coordinated adjustment of the positioning member 4234a and the angle adjustment member 4234b, after the first mounting plate 4232 is adjusted to an appropriate position, the first mounting plate 4232 can be locked in the adjusted position, thereby avoiding adjustment failure due to loosening of the first mounting plate 4232, and effectively improving the reliability and practicality of the first angle adjustment assembly 4234.

[0064] Combined with reference Figure 7 and Figure 8 , one end of the angle adjustment member 4234b can be in contact with the corresponding fixing member 4233c, and the other end of the angle adjustment member 4234b can be rotatably connected to the first mounting plate 4232. The angle adjustment member 4234b can be used to rotate and drive the first mounting plate 4232 to move in a direction close to or away from the fixing member 4233c. During the rotation of the angle adjustment member 4234b, one end of the angle adjustment member 4234b can always be in contact with the fixing member 4233c, so that a stable connection relationship is formed between the angle adjustment member 4234b and the fixing member 4233c, and the first mounting plate 4232 is driven to move in a direction close to or away from the fixing member 4233c through the other end of the angle adjustment member 4234b, which effectively improves the adjustment efficiency and stability of the angle adjustment member 4234b.

[0065] In some embodiments, in conjunction with Figure 4 and Figure 7, multiple first angle adjustment components 4234 are arranged at intervals along the edge of the first mounting plate 4232. Specifically, the number of the first angle adjustment components 4234 can be four, and the four first angle adjustment components 4234 are arranged on the four vertices of the first mounting plate 4232. The reflection angle of the second reflector 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 accurately adjusted, thereby improving the adjustment precision and accuracy of the second reflector 422, and effectively ensuring the reflection effect of the second reflector 422.

[0066] In some embodiments, in conjunction with Figure 1 , Figure 4 and Figure 6 The fixing seat 4231 has a beam entrance 4231a connected to the light-guiding cavity 4233, and the second path 411 passes through the beam entrance 4231a and extends to the first portion 4233a. The fixing seat 4231 is formed with a beam entrance 4231a on the side facing the light-emitting element 410, and the light-emitting element 410 can be arranged close to the beam entrance 4231a. The size of the beam entrance 4231a can be larger than the diameter of the light-emitting element 410, so as to guide all the second light beam emitted by the light-emitting element 410 into the fixing seat 4231, thereby avoiding the light energy loss of the light-emitting element 410. In this way, while ensuring the transmission effect of the second light beam emitted by the light-emitting element 410, the mechanical structure of the shooting device 1 can also be simplified, thereby realizing the precision and miniaturization of the shooting device 1.

[0067] In some embodiments, again in conjunction with Figure 1 , Figure 4 and Figure 6 , the fixing seat 4231 has a beam outlet 4231b connected to the light guide cavity 4233, and the second light beam passes through the beam outlet 4231b and extends to the second portion 4233b after being reflected by the second reflector 422. Specifically, the fixing seat 4231 is formed with a beam outlet 4231b on the side facing the camera 110, and the camera 110 can be arranged close to the beam outlet 4231b. The size of the beam outlet 4231b can be smaller than the diameter of the camera 110, so that the second light beam reflected by the second reflector 422 is fully transmitted to the shooting optical path 111 of the camera 110, which effectively improves the shooting effect of the camera 110. The plane where the beam entrance 4231a is located and the plane where the beam outlet 4231b is located can be perpendicular to each other, so that the second light beam injected through the beam entrance 4231a can be directly emitted from the beam outlet 4231b under the action of the second reflector 422, thereby reducing the volume of the fixing seat 4231 and the required operating space. In this way, while ensuring the transmission effect of the second light beam emitted by the light emitting element 410 and the shooting effect of the camera 110, the mechanical structure of the shooting device 1 is further simplified, and the precision and miniaturization of the shooting device 1 are achieved.

[0068] Combined with reference Figure 1 , Figure 2 and Fig.10 , the first reflector 30 may be connected to a first reflection adjustment component 50. The first reflection adjustment component 50 may include a fixing plate 510, a second mounting plate 520, and a second angle adjustment component. The first reflector 30 may be disposed on the second mounting plate 520. The second angle adjustment component may include at least one of a first adjustment component 531, a second adjustment component 532, and a third adjustment component 533. The first adjustment component 531 may be configured to be arranged along a third direction (such as Fig. 9 The second adjustment component 532 can be configured to adjust the angle of the second mounting plate 520 relative to the fixing plate 510 along the fourth direction (eg, Fig. 9 The third adjustment component 533 can be configured to adjust the angle of the second mounting plate 520 relative to the fixing plate 510 along the fifth direction (such as Fig. 9 The first reflector 30 is arranged on the second mounting plate 520, so adjusting the angle of the second mounting plate 520 relative to the fixing plate 510 is to adjust the angle of the first reflector 30 relative to the fixing plate 510. The first reflector 30 can be fixed on the second mounting plate 520 by pasting. Of course, it is not ruled out that the first reflector 30 can be fixed on the second mounting plate 520 by other connection 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 with each other. In this way, the second angle adjustment component includes at least one of the first adjustment component 531, the second adjustment component 532 and the third adjustment component 533. The angle of one direction of the first reflector 30 is correspondingly adjusted by one adjustment component, thereby improving the accuracy of the angle adjustment and avoiding the first reflector 30 from having a large deviation from the target direction and target angle to be adjusted.

[0069] Specifically, a hollow light-through hole 511 is provided at a position of the fixing plate 510 corresponding to the first reflector 30 , thereby ensuring that the first light beam emitted by the laser source assembly 20 can reach the material along the first path 310 through the first reflector 30 .

[0070] Preferably, the second angle adjustment component may include a first adjustment component 531, a second adjustment component 532 and a third adjustment component 533. The number of the first adjustment component 531, the second adjustment component 532 and the third adjustment component 533 may all be one. The connecting line of the first adjustment component 531, the second adjustment component 532 and the third adjustment component 533 projected onto the second mounting plate 520 may be a triangle. Specifically, the first adjustment component 531, the second adjustment component 532 and the third adjustment component 533 may be arranged on three corners of the fixing plate 510 or the second mounting plate 520. In this way, by adjusting the angle of one direction of the first reflector 30 correspondingly by each adjustment component, the accuracy of the 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 adjustment component may also include a variety of situations, for example, the second angle adjustment component may include a situation where the first adjustment component 531 (such as Figure 1 and Figure 2 ), the second angle adjustment component may also include a second adjustment component 532, etc. According to different application scenarios, corresponding second angle adjustment components may be provided, thereby saving costs.

[0072] Combined with reference Figures 9 to 11 , the first adjustment component 531 may include a first adjustment member 5311, a first mounting hole 5312 provided on the second mounting plate 520, and a V-shaped groove 5313 (i.e., a long tapered groove) provided on the fixing plate 510. The first adjustment member 5311 passes through the first mounting hole 5312 and rotatably abuts against the V-shaped groove 5313. In this way, the first adjustment component 531 can accurately adjust the angle of the first reflector 30 in the third direction, avoiding the situation that the first reflector 30 has a large deviation from the target direction and target angle to be adjusted. The first adjustment member 5311 may be a screw or a bolt, etc. The first mounting hole 5312 may be a threaded hole or a through hole, etc. Preferably, one end of the first adjustment member 5311 abutting against the V-shaped groove 5313 may be a spherical structure, so as to facilitate the first adjustment member 5311 to move in the V-shaped groove 5313 along the third direction, thereby realizing the angle adjustment of the first reflector 30 along the third direction. Of course, it is not excluded that the end of the first adjusting member 5311 that abuts against the V-shaped groove 5313 may be a hemispherical structure, etc. In some embodiments, the first adjusting member 5311 rotatably abuts against the V-shaped groove 5313, thereby accurately adjusting the pitch angle of the first reflector 30.

[0073] Specifically, a first sleeve 5314 may be inserted into the first mounting hole 5312. The first sleeve 5314 may be threadedly connected to the first adjusting member 5311. The first adjusting member 5311 is connected to the first mounting hole 5312 through the first sleeve 5314, thereby preventing the second mounting plate 520 from being damaged and saving costs.

[0074] Furthermore, a first locking nut 5315 may be disposed above the first sleeve 5314, and the first locking nut 5315 may be threadedly connected to the first adjusting member 5311. This further improves the stability of the connection between the first adjusting member 5311 and the second mounting plate 520, and prevents the first adjusting member 5311 from being loosened relative to the second mounting plate 520 when adjusting the angle of the second mounting plate 520 relative to the fixed plate 510.

[0075] Combined with reference Fig.11 and Fig.13 , a plate-like member 5313b may be provided on the groove side wall 5313a of the V-shaped groove 5313. The first adjusting member 5311 may be rotatably pressed against the plate-like member 5313b. Specifically, the material of the fixing plate 510 may be aluminum, which is a lighter material, but has a lower hardness. Therefore, a plate-like member 5313b made of stainless steel may be provided on the groove side wall 5313a of the V-shaped groove 5313 to ensure hardness. The shape of the plate-like member 5313b may be square, which is not only convenient for fitting with the groove side wall 5313a of the V-shaped groove 5313, but also easy for processing and manufacturing. The number of the plate-like members 5313b may be two, and the two plate-like members 5313b may be respectively placed on two relatively long groove side walls 5313a. The present application does not specifically limit the shape and number of the plate-like members 5313b. In some embodiments, the first adjusting member 5311 can sequentially pass through the first locking nut 5315 and the first sleeve 5314 in the first mounting hole 5312, and can rotatably abut against the plate-shaped member 5313b. In this way, the groove sidewall 5313a of the V-shaped groove 5313 is separated from the first adjusting member 5311 by the plate-shaped member 5313b, avoiding direct contact between the groove sidewall 5313a of the V-shaped groove 5313 and the first adjusting member 5311, thereby avoiding damage or deformation of the groove sidewall 5313a of the V-shaped groove 5313 due to the abutment of the first adjusting member 5311.

[0076] Combined with reference Fig. 9 , Fig.10 and Fig.14, the first adjustment component 531 may further include a first elastic member 5316. One end of the first elastic member 5316 may be connected to the fixing plate 510, and the other end of the first elastic member 5316 may be connected to the second mounting plate 520. It should be noted that the force exerted by the first elastic member 5316 on the fixing plate 510 and the second mounting plate 520 is opposite to the force exerted by the first adjustment member 5311 on the fixing plate 510 and the second mounting plate 520. Specifically, the first elastic member 5316 may be a spring or the like. In this way, by providing the first elastic member 5316, the accuracy of the first adjustment component 531 in adjusting the angle of the first reflective member 30 in the third direction is further increased.

[0077] Further, the first elastic member 5316 may have a first elastic portion, a first fixing portion, and a second fixing portion. Specifically, the first fixing portion and the second fixing portion may both be positioning pins. The fixing plate 510 may have a first fixing hole 512, and the second mounting plate 520 may have a second fixing hole 521. The first fixing portion is inserted into the first fixing hole 512, and the second fixing portion is inserted into the second fixing hole 521. Both ends of the first elastic member 5316 may be hooks, and the two ends may be hung on the first fixing portion and the second fixing portion, respectively. The stability of the connection between the first elastic member 5316 and the fixing plate 510 and the second mounting plate 520 is ensured, and it is easy to install or disassemble.

[0078] Combined with reference Fig. 9 , Fig.10 and Fig.12 , the second adjustment component 532 may include a second adjustment member 5321, a second mounting hole 5322 provided on the second mounting plate 520, and a tapered groove 5323 provided on the fixing plate 510. The second adjustment member 5321 passes through the second mounting hole 5322 and rotatably abuts against the tapered groove 5323. In this way, the second adjustment component 532 can accurately adjust the angle of the first reflector 30 in the fourth direction, avoiding the situation that the first reflector 30 deviates greatly from the target direction and target angle to be adjusted. The second adjustment member 5321 may be a screw or a bolt, etc. The second mounting hole 5322 may be a threaded hole or a through hole, etc. Preferably, one end of the second adjustment member 5321 abutting against the tapered groove 5323 may be a spherical structure, so as to facilitate the second adjustment member 5321 to move in the tapered groove 5323 along the fourth direction, thereby realizing the angle adjustment of the first reflector 30 along the fourth direction. Of course, it is not excluded that one end of the second adjustment member 5321 abutting against the tapered groove 5323 may be a hemispherical structure, etc. In some embodiments, the second adjusting member 5321 is rotatably pressed against the conical groove 5323 , so as to accurately adjust the height of the first reflective member 30 (ie, increase the distance between the second mounting plate 520 and the fixing plate 510 ).

[0079] Specifically, a second sleeve 5324 may be inserted into the second mounting hole 5322. The second sleeve 5324 may be threadedly connected to the second adjusting member 5321. The second adjusting member 5321 is connected to the second mounting hole 5322 through the second sleeve 5324, thereby preventing the second mounting plate 520 from being damaged and saving costs.

[0080] Combined with reference Figures 9 to 14 , the second adjustment component 532 may further include a second elastic member 5325. One end of the second elastic member 5325 may be connected to the fixed plate 510, and the other end of the second elastic member 5325 may be connected to the second mounting plate 520. It should be noted that the force exerted by the second elastic member 5325 on the fixed plate 510 and the second mounting plate 520 is opposite to the force exerted by the second adjustment member 5321 on the fixed plate 510 and the second mounting plate 520. Specifically, the second elastic member 5325 may be a spring or the like. In this way, by providing the second elastic member 5325, the accuracy of the second adjustment component 532 in adjusting the angle of the first reflector 30 in the fourth direction is further increased.

[0081] Further, the second elastic member 5325 may have a second elastic portion, a third fixing portion and a fourth fixing portion. Specifically, the third fixing portion and the fourth fixing portion may both be positioning pins. The fixing plate 510 may have a third fixing hole 513, and the second mounting plate 520 may have a fourth fixing hole 522. The third fixing portion is inserted into the third fixing hole 513, and the fourth fixing portion is inserted into the fourth fixing hole 522. Both ends of the second elastic member 5325 may be hooks, and the two ends may be hung on the third fixing portion and the fourth fixing portion, respectively. The stability of the connection between the second elastic member 5325 and the fixing plate 510 and the second mounting plate 520 is ensured, and it is easy to install or disassemble.

[0082] Again, refer to Figures 9 to 11, the third adjustment component 533 may include a third adjustment member 5331, a third mounting hole 5332 provided on the second mounting plate 520, and a flat bottom groove 5333 provided on the fixing plate 510. The third adjustment member 5331 passes through the third mounting hole 5332 and rotatably abuts against the flat bottom groove 5333. In this way, the third adjustment component 533 can accurately adjust the angle of the first reflector 30 in the fifth direction, avoiding the situation that the first reflector 30 has a large deviation from the target direction and target angle to be adjusted. Preferably, one end of the third adjustment member 5331 abutting against the flat bottom groove 5333 may be a spherical structure, so as to facilitate the third adjustment member 5331 to move in the flat bottom groove 5333 along the fifth direction, thereby realizing the angle adjustment of the first reflector 30 along the fifth direction. Of course, it is not excluded that one end of the third adjustment member 5331 abutting against the flat bottom groove 5333 may be a hemispherical structure, etc. In some embodiments, the third adjusting member 5331 is rotatably pressed against the flat bottom groove 5333 , so as to accurately adjust the left and right inclination angles of the first reflecting member 30 .

[0083] Specifically, a third sleeve 5334 may be inserted into the third mounting hole 5332. The third sleeve 5334 may be threadedly connected to the third adjusting member 5331. The third adjusting member 5331 is connected to the third mounting hole 5332 through the third sleeve 5334, thereby preventing the second mounting plate 520 from being damaged and saving costs.

[0084] Furthermore, a second locking nut 5335 may be disposed above the third sleeve 5334, and the second locking nut 5335 may be threadedly connected to the third adjusting member 5331. This further improves the stability of the connection between the third adjusting member 5331 and the second mounting plate 520, and prevents the third adjusting member 5331 from being 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 Fig.11 and Fig.13, a pad 5333b may be provided on the bottom wall 5333a of the flat bottom groove 5333, and the third adjusting member 5331 may be rotatably pressed against the pad 5333b. Specifically, the material of the fixing plate 510 may be aluminum, which is a lighter material, but has a lower hardness, so a pad 5333b made of stainless steel may be provided on the bottom wall 5333a of the flat bottom groove 5333 to ensure hardness. The pad 5333b may be in the shape of a round cake, which is not only convenient for fitting with the bottom wall 5333a of the flat bottom groove 5333, but also easy for processing and manufacturing. In some embodiments, the third adjusting member 5331 may pass through the second locking nut 5335 and the third sleeve 5334 in the third mounting hole 5332 in sequence, and may be rotatably pressed against the pad 5333b. In this way, the bottom wall 5333a of the flat-bottomed groove 5333 is separated from the third adjusting member 5331 by the cushion block 5333b, thereby avoiding direct contact between the bottom wall 5333a of the flat-bottomed groove 5333 and the third adjusting member 5331, thereby avoiding damage or deformation of the bottom wall 5333a of the flat-bottomed groove 5333 caused by the push of the third adjusting member 5331.

[0086] Combined with reference Fig. 9 , Fig.11 , Fig.13 and Fig.14 , the third adjustment component 533 may also include a third elastic member 5336. One end of the third elastic member 5336 may be connected to the fixed plate 510, and the other end of the third elastic member 5336 may be connected to the second mounting plate 520. It should be noted that the force generated by the third elastic member 5336 on the fixed plate 510 and the second mounting plate 520 is opposite to the force generated by the third adjustment member 5331 on the fixed plate 510 and the second mounting plate 520. Specifically, the third elastic member 5336 may be a spring or the like. In this way, by providing the third elastic member 5336, the accuracy of the third adjustment component 533 in adjusting the angle of the first reflector 30 in the fifth direction is further increased. Further, the third elastic member 5336 may have a third elastic portion, a fifth fixing portion and a sixth fixing portion. Specifically, the fifth fixing portion and the sixth fixing portion may both be positioning pins. The fixed plate 510 may have a fifth fixing hole 514, and the second mounting plate 520 may have a sixth fixing hole 523. The fifth fixing portion is inserted into the fifth fixing hole 514, and the sixth fixing portion is inserted into the sixth fixing hole 523. Both ends of the third elastic member 5336 may be hooks, and both ends may be hung on the fifth fixing portion and the sixth fixing portion, respectively. This ensures the stability of the connection between the third elastic member 5336 and the fixing plate 510 and the second mounting plate 520, and facilitates installation or removal.

[0087] Specifically, in the case where the second angle adjustment assembly may include a first adjustment assembly 531, a second adjustment assembly 532, and a third adjustment assembly 533. The first elastic member 5316 may be disposed between the first adjustment member 5311 and the second adjustment member 5321. In order to ensure the accuracy of the second adjustment assembly 532 in adjusting the angle of the first reflector 30, there may be two second elastic members 5325, one of which may be located between the first adjustment member 5311 and the second adjustment member 5321, and the other of which may be located between the second adjustment member 5321 and the third adjustment member 5331. The third elastic member 5336 may be disposed between the second adjustment member 5321 and the third adjustment member 5331.

[0088] In some embodiments, see Fig. 9 A dustproof plate 540 may be provided on the end surface of the second mounting plate 520 away from the fixing plate 510. The first reflector 30 may be provided between the second mounting plate 520 and the dustproof plate 540. The dustproof plate 540 is used to prevent external dust from entering the inner wall of the first reflector 30 through the mounting process holes or gaps, causing the first reflector 30 to become dirty. The dustproof plate 540 and the second mounting plate 520 may be connected and fixed by means of screw connection. Of course, the dustproof plate 540 and the second mounting plate 520 may also be connected by means of snap connection, adhesive connection, or other connection methods.

[0089] In some embodiments, the first reflection adjustment component 50 may be connected to a third optical path component. An end of the third optical path component away from the first reflection adjustment component 50 may be connected to an objective lens. The first light beam may be reflected by the first reflector 30 and then pass through the third optical path component along the first path 310 to reach the objective lens. After being focused by the objective lens, the energy is concentrated on the wafer, so that wafer cutting can be performed.

[0090] In some embodiments, the photographing device 1 may further include a driving assembly. The driving assembly may include a driving member, a screw and a movable plate. The driving member may drive the screw to drive the movable plate to move. The movable plate may be connected to the camera assembly 10 and the light source assembly 40. In this way, the accuracy of adjusting the relative position relationship between the camera 110 and the material is improved, and the photographing effect of the camera 110 is improved.

[0091] In some embodiments, the driving assembly may further include a grating ruler, which may be connected to the driving member. The feedback of the grating ruler further improves the accuracy of adjusting the relative position relationship between the camera 110 and the material, thereby improving the shooting effect of the camera 110.

[0092] The working process of the shooting device 1 is described in detail below. The light emitting element 410 can emit a second light beam, which is reflected by the second reflective element 422 along the second path 411. The reflected second light beam is transmitted to the shooting light path 111 along the third path 421, and then passes through the refractor 460 at the intersection of the shooting light path 111 and the third path 421, and irradiates the material along the shooting light path 111. The laser source assembly 20 emits a first light beam, which is reflected by the first reflective element 30 and reaches the material along the first path 310 to cut the material. The material reflects the second light beam and reaches the camera 110 along the shooting light path 111, thereby obtaining a real-time image of the material.

[0093] According to another aspect of the present invention, a laser processing device is provided. The laser processing device may include a stage and the above-mentioned shooting device 1. The stage may be used to carry materials, and the stage may be arranged below the shooting device 1. Since the above-mentioned shooting device 1 has the above-mentioned beneficial effects, the laser processing device including the above-mentioned shooting device 1 also has the above-mentioned beneficial effects, which will not be described one by one here.
