[0029] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] The various specific technical features in the various embodiments described in the specific implementation methods can be combined in various ways without contradiction. For example, different implementation methods can be formed by combining different specific technical features. In order to avoid unnecessary repetition, the various possible combinations of the specific technical features in the present invention will not be described separately.

[0031] It should also be noted that, in order to avoid obscuring the present invention due to unnecessary details, only structures and / or processing steps closely related to the scheme of the present invention are shown in the drawings, while other details that are not closely related to the present invention are omitted.

[0032] In addition, it should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the following description, the terms "first\second\..." involved are merely used to distinguish different objects, and do not indicate that the objects have the same or related points. It should be understood that the directions described by the directions nouns such as "above", "below", "inside" and "outside" involved are all directions in normal use.

[0033] In the following specific embodiments, a stacking system, a stacking method and a method for a testing environment for an optical system are provided, wherein the stacking system can realize the functions of stacking optical systems and providing an environment for testing the optical system, that is, the stacking system can realize multiple functions; in the stacking process of the optical system, since the stacking process may apply external force, impact or high temperature to the light source or optical element in the optical system, if the light source is in a working state, the light source may be damaged during the stacking process. Therefore, those skilled in the art generally do not want the light source of the optical system to be in a working state during the stacking process, and thus will not set a power supply structure in the stacking system. However, during the stacking process, some optical elements need to be precisely positioned with the light source, and it is impossible to determine whether the optical element has been assembled in place only based on the structural characteristics of the optical element. Moreover, if during the assembly process, the light source is configured to be powered on only when a small number of optical elements that need to be precisely positioned need to be assembled, and the light source is configured to be powered off for other optical elements that do not require high positioning accuracy The non-working state can control the risk of damage to the light source during the stacking process within an acceptable range. It is on the basis of realizing this that the applicant has overcome the technical prejudice in the field and creatively proposed to set a circuit board capable of power supply in the stacking system. When assembling optical elements that need to be precisely positioned, the light source is operated through the circuit board, and the light source outputs an optical signal to the optical element, and determines whether the optical element is installed in place according to the state of the optical signal corresponding to the output of the light source. At the same time, when assembling other optical elements that do not require precise positioning, the connection between the circuit board and the light source is disconnected to put the light source in a non-working state. Moreover, since the stacking system has a circuit board capable of power supply, by reusing the circuit board, the circuit board can also provide a test environment required for testing the optical system, in which the external electromagnetic signal can be isolated and the required magnetic field can be provided to the optical system, so that the stacking system can not only be used for stacking optical systems but also for providing a test environment for testing optical systems. For a clearer description, the structure and function of the stacking system are further exemplified in conjunction with the embodiments below.

[0034] The stacking system provided in the following embodiments is used to stack optical systems. The optical system can be any system having a light source and an optical element. For ease of description, the following is combined with Figure 1 The structure of this optical system will be described exemplarily.

[0035] The optical system 1 includes: a base plate 10, a light source 20, a sensor device 30, a polarizer 40 and a functional component 50. The sensor device 30 is fixed to the base plate 10. The sensor device 30 is a device sensitive to weak electric signals and is used to realize the function of a sensor. For example, it is used to obtain external electromagnetic signals and to adapt the output signal of the light source 20. The light source 20 is connected to the sensor device 30 and can obtain electrical energy from the base plate 10 to output an optical signal. The polarizer 40 is fixedly connected to the light source 20 and is used to adjust the polarization direction of the optical signal output by the light source 20, so that the output optical signal oscillates in a specific plane perpendicular to the propagation direction of the optical signal. The functional component 50 is fixedly connected to the polarizer 40 and is used to process the optical signal after passing through the polarizer 40 according to the requirements of the optical system 1. For example, the functional component 50 can be an attenuation plate for attenuating the power of the optical signal. For example, the functional component 50 can be a wave plate for adjusting the phase of the optical signal. Among them, the relative angle between the polarizer 40 and the light source 20 will have a great influence on the polarization direction of the light signal output by the optical system 1, and the relative angle between the polarizer 40 and the light source 20 needs to be accurately positioned. The following is an illustrative explanation of how the stacking system realizes the stacking of optical systems and the principle of how to achieve accurate positioning of the relative angle between the polarizer 40 and the light source 20 during the stacking process in combination with various embodiments.

[0036] In some embodiments, Figure 2 As shown, the stacking system 100 includes: a circuit board 110, a clamping device 120 and a rotating device 130. The circuit board 110 has a power supply pin 111, and the power supply pin 111 is used to obtain electrical energy from the outside.

[0037] The clamping device 120 is fixed to the circuit board 110 and is used to fix the base plate 10. It can be understood that in the process of stacking the optical system, the base plate 10, the sensor device 30 and the light source 20 are fixed as a whole, and the clamping device 120 is fixedly connected to the base plate 10 through the clamping structure, so that the base plate, the sensor device 30 and the light source 20 are fixedly connected to the circuit board 110 through the clamping device 120.

[0038] The rotating device 130 is used to clamp the polarizer 40 and drive the polarizer 40 to rotate relative to the light source 20 , so as to adjust the relative angle between the polarizer 40 and the light source 20 , thereby adjusting the polarization angle of the optical signal output by the polarizer 40 .

[0039] Among them, Figure 3As shown, the circuit board 110 has a first power supply contact 112, and the first power supply contact 112 is electrically connected to the power supply pin 111, so that the power obtained by the power supply pin 111 can be transmitted to the first power supply contact 112; the clamping device 120 has a conductive structure 121, and when the clamping device 120 is fixedly connected to the base plate 10 and the clamping device 120 is fixed to the circuit board 110, the conductive structure 121 is connected to the first power supply contact 112, so that the clamping device 120 can fix the base plate 10, the sensor device 30 and the light source 20 to the circuit board 110, and can also transmit the power obtained by the power supply pin 111 to the first power supply contact 112. The power is transmitted to the bottom plate 10 through the first power supply contact 112 and the conductive structure 121, so that the bottom plate 10 can transmit the power to the light source 20, that is, the power obtained by the circuit board 110 can be supplied to the light source 20 so that the light source 20 is in a working state. At this time, the optical signal output by the light source 20 can be output after passing through the polarizer 40, and the state of the output optical signal is different according to the relative angle between the polarizer 40 and the light source 20. According to the state of the output optical signal, it can be determined whether the relative angle between the polarizer 40 and the light source 20 meets the positioning requirement, thereby achieving high-precision positioning between the polarizer 40 and the light source 20. The following is an exemplary description of a method for determining whether the polarizer 40 and the light source 20 are installed in place according to the state of the optical signal output by the polarizer 40.

[0040] Exemplarily, the state of the optical signal output by the polarizer 40 can be obtained by a polarization testing device. The polarization test includes a polarizer and a light receiver. The polarization direction of the polarizer is consistent with the target direction. The optical signal output by the polarizer 40 passes through the polarizer and then enters the light receiver. The intensity of the incident optical signal can be obtained by the light receiver. The polarization direction of the optical signal output by the polarizer 40 can be changed by rotating the polarizer 40 by the rotating device 130, thereby changing the intensity of the optical signal after passing through the polarizer. During the rotation of the polarizer 40, if the intensity of the optical signal obtained by the light receiver reaches a maximum value, it means that the polarizer 40 has made the polarization direction of the optical signal output by the polarizer 40 consistent with the polarization direction of the target. In this state, it can be determined that the relative angle between the polarizer 40 and the light source 20 meets the requirement, that is, the precise positioning between the polarizer 40 and the light source 20 is achieved. After the positioning of the polarizer 40 and the light source 20 is completed, the polarizer 40 and the light source 20 are fixedly connected by a surfactant or glue. It should be noted that the polarization testing device can be a part of the stacking system 100, that is, the stacking system 100 has its own polarization testing function, and the stacking system 100 does not need to have its own polarization testing device. The assembler can configure the polarization testing device by themselves to obtain the polarization state of the optical signal output by the polarizer 40.

[0041] It should be noted that adjusting the relative positions of system components while power is supplied can be applied to optical systems. Because optical signals rather than electrical signals are transmitted between two components, there is no risk of damage to electrical components due to sudden changes in current or voltage in the circuit, compared to adjusting the relative positions of two electrical components that transmit electrical signals when assembling a power supply system.

[0042] An embodiment of the present invention provides a stacking system of an optical system, which is used to stack optical systems. The optical system includes a base plate, a light source and a polarizer. The stacking system includes: a circuit board having a power supply pin and a first power supply contact, a clamping device for fixing the base plate and fixedly connected to the circuit board, and a rotating device for clamping the polarizer and driving the polarizer to rotate relative to the light source, wherein the power supply pin is used to obtain electric energy from the outside and transfer the electric energy to the first power supply contact, the clamping device has a conductive structure, and when the clamping device is fixedly connected to the circuit board, the conductive structure connects the first power supply contact and the base plate, so that the electric energy obtained by the circuit board can be transferred to the light source through the base plate, thereby powering the light source and enabling the light source to output an optical signal. At this time, the optical signal output by the light source can be output after passing through the polarizer, and the state of the output optical signal is different according to the relative angle between the polarizer and the light source. According to the state of the output optical signal, it can be determined whether the relative angle between the polarizer and the light source meets the positioning requirement, thereby achieving high-precision positioning between the polarizer and the light source.

[0043] In some embodiments, Figure 4 As shown, the stacking system 100 also includes a first fixed seat 140, which is made of an insulating material. The first fixed seat 140 is used to support the circuit board 110, wherein the rotating device 130 is connected to the first fixed seat 140. It can be understood that the first fixed seat 140 provides an assembly position for the rotating device 130. After the circuit board 110 is supported on the first fixed seat 140 and the relative position of the circuit board 110 and the first fixed seat 140 is determined, the relative position of the rotating device 130 and the circuit board 110 can be determined, thereby determining the relative position of the rotating device 130 and the polarizer 40, thereby making the adjustment of the polarizer 40 by the rotating device 130 more accurate. Moreover, since the first fixed seat 140 is made of an insulating material, electrical isolation between the rotating device 130 and the circuit board 110 can be achieved, thereby preventing the electrical energy obtained by the circuit board 110 from being transmitted to the polarizer 40 by the rotating device 130, thereby reducing the risk of slight deformation of the polarizer 40 due to power-on, thereby affecting the optical performance of the polarizer 40.

[0044] In some embodiments, Figure 5 As shown, Figure 4The first fixing seat 140 in the embodiment includes a fixing bottom wall 141 and a fixing side wall 142. The fixing bottom wall 141 has a first fixing surface 143, which can be, for example, the top surface of the fixing bottom wall 141, and the circuit board 110 is fixed to the first fixing surface 143; the fixing side wall 142 extends from the first fixing surface 143 to form a second fixing surface 144, that is, the end surface of the fixing side wall 142 away from the first fixing surface 143 forms the second fixing surface 144, and the rotating device 130 is fixed to the second fixing surface, wherein, when the circuit board 110 is fixed to the fixing bottom wall 141, the dimension D1 of the power supply pin 111 protruding from the first fixing surface 143 is smaller than the dimension D2 of the second fixing surface 144 protruding from the first fixing surface 143, which can be understood as When the circuit board 110 is assembled on the first fixing surface 143, the second fixing surface 144 is higher than the top surface of the power supply pin 111, thereby reducing the possibility of movement interference between the rotating device 130 and the power supply pin 111. At the same time, by increasing the distance between the installation position of the rotating device 130 and the power supply pin 111, the electrical isolation between the power supply pin 111 and the rotating device 130 is made more reliable. At the same time, by making the extension direction of the fixed side wall 142 different from the extension direction of the fixed bottom wall 141, the distance between the installation position of the rotating device 130 and the power supply pin 111 can be increased without increasing the size of the first fixing surface 143.

[0045] In some embodiments, Figure 6 As shown, Figure 4The rotating device 130 in the embodiment includes: a support rod 131, a fixing structure 132, a rotating structure 133 and a clamping structure 134. The support rod 131 is fixed to the first fixing seat 140; it extends in a direction away from the first fixing seat 140 to form a remote end, that is, along the extension direction of the support rod 131, the end surface of the support rod 131 away from the first fixing seat 140 forms the remote end; the fixing structure 132 is fixedly connected to the support rod 131, and the connection position of the fixing structure 132 and the support rod is close to the remote end. It can be understood that by moving the support rod 131 away from the fixing seat, the connection position of the fixing structure 132 and the support rod 131 can be located at a position away from the first fixing seat 140, thereby reducing the possibility of assembly interference between the fixing structure 132 and the first fixing seat 140. The rotating structure 133 is rotatably connected to the fixed structure 132, and the clamping structure 134 is fixedly connected to the rotating structure 133 and can clamp the polarizer 40. The rotating structure 133 can drive the rotating structure to rotate relative to the fixed structure 132, thereby driving the clamping structure 134 to rotate relative to the fixed structure 132, and then driving the polarizer 40 to rotate relative to the fixed structure 132. Since the fixed structure 131 is fixedly connected to the circuit board 110 through the first fixing seat 140, and the light source 20 is fixedly connected to the circuit board 110, the rotating structure 133 can drive the polarizer 40 to rotate relative to the light source 20. The specific structures of the rotating structure, the fixed structure and the clamping structure are exemplarily described below to illustrate the principle that the rotating structure can rotate relative to the fixed structure and the clamping structure can clamp the polarizer 40.

[0046] The side wall of the fixed structure is a cylindrical curved surface and a positioning groove is formed in the side wall. The outer surface of the rotating structure protrudes to form a positioning boss, and the positioning boss extends into the positioning groove to realize the vertical limitation of the rotating structure and the fixed structure; a gear ring is arranged in the positioning groove, and the positioning boss is provided with a gear rotatably connected to the positioning boss, the gear is meshed with the gear ring, and the rotating structure has a servo motor, the servo motor can drive the gear to rotate, and the action force between the gear and the gear ring can drive the gear to revolve around the vertical center axis of the gear ring, thereby driving the rotating structure to rotate relative to the fixed structure; at least two rotating structures are spaced around the vertical center axis of the gear ring, and at least two clamping structures protrude from the rotating structure. During the stacking process, the vertical center axis of the gear ring coincides with the vertical center axis of the polarizer, and multiple clamping structures surround the polarizer and contact the polarizer, thereby realizing the clamping of the polarizer.

[0047] The clamping structure is connected to the rotating structure so that the clamping structure can drive the polarizer to rotate. Optionally, the clamping structure is fixedly connected to the rotating structure. Optionally, the rotating structure forms a strip structure similar to an L shape, which includes a long arm extending vertically and a short arm extending horizontally. The long arm is rotatably connected to the fixed structure, and the short arm is used to carry the clamping structure. At the same time, the rotating structure also has a pressing sheet that can slide along the extension direction of the long arm. By moving the pressing sheet downward, the clamping structure can be clamped between the short arm and the pressing sheet, so that the rotation of the rotating structure can be transmitted. By moving the pressing plate upward, the clamping structure can be released. At this time, the rotation of the rotating structure will not be transmitted to the clamping structure. It can be understood that during the assembly of the rotating device, the pressing plate releases the clamping structure, and the rotational movement generated during the assembly process will not be transmitted to the clamping structure, thereby not driving the polarizer to rotate. After the assembly is completed, when the angle of the polarizer needs to be adjusted, the pressing plate will press the clamping structure so that the clamping structure drives the polarizer to rotate, thereby further improving the adjustment accuracy of the angle of the polarizer.

[0048] In some embodiments, Figure 7 As shown, the stacking system 100 further includes a second fixing seat 150, which is used to be fixedly connected to the clamping device 120, wherein the clamping device 120 is detachably connected to the second fixing seat and is connected to the second fixing seat. Figure 2 The circuit board 110 is detachably connected, and it can be understood that after the stacking of the polarizer 40 and the light source 20 is completed, the clamping device 120 can be removed from the circuit board 110 and assembled in the second fixing seat 150, so that the functional component 50 and the polarizer 40 can be assembled in an unpowered state, that is, in the state of assembling optical devices that do not require high-precision positioning, the positioning of the base plate 10 is achieved by providing an unpowered second fixing seat 150 and the stacking of optical devices that do not require high-precision positioning is completed when the light source 20 is in a non-working state, thereby reducing the possibility of damage to the light source 20.

[0049] In some embodiments, Figure 8As shown, the stacking system 100 also includes: a shielding structure 161 and a coil 162, the shielding structure 161 is connected to the circuit board 110 and the shielding structure 161 surrounds and forms an electromagnetic shielding space 163, which can be understood as, the shielding structure 161 is made of a through-hole electromagnetic shielding material, and there is a cavity inside the shielding structure 161, and the cavity forms the electromagnetic shielding space 163; the coil 162 is fixedly connected to the circuit board 110, and when the coil 162 is fixedly connected to the circuit board 110, the coil 162 is located inside the electromagnetic shielding space 163, and the power supply pin 111 is located outside the electromagnetic shielding space 163, which can be understood as, the shielding structure 161 is used to isolate the external magnetic field, and the external magnetic field can be understood as the earth's magnetic field, the electromagnetic magnetic field generated by the power supply pin 111, and the electromagnetic magnetic field generated by other electronic devices or cables around the optical system, so that the optical system is only affected by the electromagnetic field generated by the coil 162, and then the performance of the optical system in a specific magnetic field can be tested. For example, the polarization angle of the optical signal output by the optical system in different magnetic fields can be tested.

[0050] Among them, the circuit board 110 also includes a second power supply contact 113, which is electrically connected to the power supply pin 111 so that the power supply pin 111 can obtain electrical energy, and when the shielding structure 161 and the circuit board 110 are fixed, the second power supply contact 113 is located inside the electromagnetic shielding space 163, and when the coil 162 is fixed to the circuit board 110, the coil 162 is in contact with the second power supply contact 113, that is, the circuit board 110 can supply power to the coil 162 located in the electromagnetic shielding space 163 through the second power supply contact 113, supply power to the light source through the first power supply contact 112, and supply power to the coil through the second power supply contact 113, so that the circuit board 110 can provide power for the test of the optical system; at the same time, the circuit board 1 10 also has a mounting groove 114, and the mounting groove 114 is used for the shielding structure 161 to pass through. Exemplarily, the shielding structure 161 includes a split shielding cap and a shielding plate, and the shielding plate is located below the circuit board 110. The shielding cap passes through the mounting groove 114 and is fixedly connected to the shielding plate, so that the shielding structure 161 can completely surround the optical system and the coil 162 on the circuit board 110. In summary, in addition to being able to power the light source during the stacking of the optical system, the circuit board 110 can also be reused during the testing of the optical system to provide an installation space for the shielding structure 161 and power the light source 20 and the coil 162, thereby providing a test environment for the testing of the optical system, that is, the stacking system 100 can achieve multiple functions.

[0051] The embodiment of the present invention also provides a stacking method of an optical system, wherein the stacking method is as shown in the accompanying drawings of the specification. Figures 2 to 8 Any of the stacking systems shown in FIG. Figure 1The optical systems shown are stacked.

[0052] In some embodiments, Fig. 9 As shown, Fig. 9 A schematic flow chart of a first optical system stacking method provided in an embodiment of the present invention, the stacking method comprising:

[0053] Step S101: fix the base plate and the light source fixed to the base plate by a clamping device, fix the clamping device to the circuit board, and make the conductive structure of the clamping device contact with the first power supply contact.

[0054] It can be understood that the base plate, the light source and the circuit board are fixed by the clamping device. At the same time, when the clamping device and the circuit board are assembled, the electric energy of the circuit board can be transmitted to the base plate by the first power supply contact and the conductive structure, thereby transmitting the electric energy to the light source through the base plate, thereby realizing power supply to the light source.

[0055] Step S102: Control the rotating device to connect with the polarizer and rotate the polarizer relative to the light source until the optical signal output by the polarizer meets a preset condition.

[0056] It can be understood that the relative angle between the polarizer and the light source is adjusted by the rotating device, and whether the relative angle between the polarizer and the light source reaches the target is determined by the state of the light signal output by the polarizer. Exemplarily, the state of the light signal output by the polarizer can be obtained by a polarization testing device. The polarization test includes a polarizer and a light receiver. The polarization direction of the polarizer is consistent with the target direction. The light signal output by the polarizer passes through the polarizer and is incident on the light receiver. The intensity of the incident light signal can be obtained by the light receiver. Rotating the polarizer by the rotating device can change the polarization direction of the light signal output by the polarizer, thereby changing the intensity of the light signal after passing through the polarizer. In the process of rotating the polarizer, if the intensity of the light signal obtained by the light receiver reaches a maximum value, it means that the polarizer has made the polarization direction of the light signal output by the polarizer consistent with the polarization direction of the target. In this state, it can be determined that the relative angle between the polarizer and the light source meets the requirements.

[0057] Step S103: fixedly connecting the polarizer to the light source and separating the rotating device from the polarizer.

[0058] It can be understood that when the relative angle between the polarizer and the light source is adjusted to the target angle, a fixing force is formed between the polarizer and the light source through glue or molecular bonds through epoxy resin glue or surfactant, thereby fixing the polarizer and the light source.

[0059] In some embodiments, Fig.10 As shown, Fig.10A schematic diagram of a flow chart of a second optical system stacking method provided by an embodiment of the present invention, and Fig. 9 The stacking method shown is different in that Fig.10 Step S103 includes:

[0060] Step S201: Control the circuit board to stop supplying power to the light source.

[0061] It can be understood that after the relative angle between the light source and the polarizer is adjusted and before the polarizer is fixedly connected to the light source, the power supply to the light source is stopped, and at the same time, the polarizer is clamped by the rotating device so that the relative angle between the polarizer and the light source remains unchanged, thereby reducing the damage to the light source in the subsequent process of fixing the light source and the polarizer, and further reducing the possibility of damage to the light source during the stacking process. Optionally, by setting a switch between the electrical connection between the power supply pin and the external light source, the electrical connection between the power supply pin and the light source can be disconnected through the switch, so that the circuit board stops supplying power to the light source. Optionally, by disconnecting the power supply pin from the external power supply, the circuit board loses external power supply, so that the circuit board stops supplying power to the light source.

[0062] Step S202: placing a fixing glue between the polarizer and the light source to fix the polarizer and the light source.

[0063] It can be understood that the fixation between the polarizer and the light source is achieved by gluing, wherein, in order to improve the fixation reliability between the polarizer and the light source, the polarizer and the light source are fixed by epoxy resin glue. Since the light source is already in a power-off state at this time, the possibility of the light source being damaged by the heat of the epoxy resin glue is reduced.

[0064] Step S203: Control the rotating device to separate from the polarizing element.

[0065] It can be understood that after the polarizer and the light source are fixed, the optional device is separated from the polarizer, thereby reducing the possibility of interference between the subsequent assembly process and the rotating device.

[0066] In some embodiments, the optical system further includes a functional component, the stacking system further includes a second fixing seat, and the clamping device is detachably connected to the circuit board, such as Fig.11 As shown, Fig.11 A schematic diagram of a process flow of a third optical system stacking method provided by an embodiment of the present invention, and Fig. 9 The stacking method shown is different in that Fig. 9 After step S103 in the stacking method, the stacking method further includes:

[0067] Step S301, remove the clamping device from the circuit board, and fix the clamping device to the second fixing seat.

[0068] It can be understood that the optical system also includes functional parts, and the assembly positioning accuracy of the functional parts and the polarization parts is low, so the clamping device is removed from the circuit board and the functional parts are assembled in the second fixed seat, that is, the functional parts are stacked and assembled in a non-powered environment.

[0069] Optionally, the clamping device is separated from the circuit board by a low-vibration disassembly method. For example, the clamping device and the circuit board are connected by glue, and the glue is melted by a hot air blower to separate the clamping device from the circuit board, thereby reducing the impact of vibration generated during the disassembly of the clamping device on the optical system.

[0070] Step S302: fixedly connecting the functional component to the polarizing component.

[0071] It can be understood that the polarizing element is positioned on the second non-powered fixing seat, and the functional element is fixedly connected to the polarizing element.

[0072] The embodiment of the present invention also provides a method for building a test environment for an optical system, wherein the optical system is as shown in the attached specification. Figure 1 The optical system shown in the figure is tested by Figure 8 The stacking system shown is implemented. This test is used to test the performance of the optical system in a specific magnetic field environment. The test environment requires shielding the external magnetic field of the optical system and also requires providing a specific magnetic field. The specific steps of the method for setting up the test environment are exemplified below.

[0073] In some embodiments, Fig.12 As shown, Fig.12 A flow chart of a method for building a test environment provided by an embodiment of the present invention, the method comprising:

[0074] Step S401: fixedly connect the clamping device to the optical system, fixedly connect the clamping device to the circuit board, and connect the clamping device to the first power supply contact.

[0075] That is, the optical system is fixedly connected to the circuit board through the clamping device, and the circuit board can supply power to the light source through the first power supply contact.

[0076] Step S402: fix the coil to the circuit board and make the coil contact the second power supply contact.

[0077] That is, the coil is fixed by the circuit board and power is supplied to the coil through the circuit board, so that a specific magnetic field environment can be generated by the coil.

[0078] Step S403: Pass the shielding structure through the installation slot, and place the coil and the optical system in the electromagnetic shielding space surrounded by the shielding structure.

[0079] It can be understood that the electromagnetic shielding structure is passed through the installation groove set on the circuit board, so that the shielding structure can completely surround the optical system and coil on the circuit board, so that the shielding structure can shield the magnetic field outside the electromagnetic shielding space, so that the optical element is only affected by the electromagnetic field generated by the coil.

[0080] The above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the present invention.
