Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0044] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, if the meaning of "and / or" appearing in the full text is to include three parallel schemes, taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme that satisfies both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0046] In the related art, the optical detection device is equipped with a calibration plate and a detection plate. The calibration plate is used to reflect the detection light to calibrate the parameters of the transmitting device. The detection plate allows the detection light to pass through to detect the object to be detected. During calibration, the detection plate needs to be disassembled and replaced with the calibration plate. After the calibration is completed, the calibration plate needs to be disassembled and replaced with the detection plate, which is very cumbersome to operate.

[0047] The present invention provides an optical detection device, which can conveniently and quickly realize the calibration of a transmitting device.

[0048] In one embodiment of the present invention, Figure 1 and Figure 2 As shown, the optical detection device comprises:

[0049] An installation base 100, a transmitter 710 and a receiver 720 installed on the installation base 100, wherein the transmitter 710 is used to transmit a detection light, and the receiver 720 is used to receive a reflected light formed after the detection light is reflected; and

[0050] A movable member 200 movably connected to the mounting base 100 so that the movable member 200 has a first position and a second position;

[0051] Among them, a calibration area and a detection area are distributed on the movable part 200. At the first position, the detection light is reflected at the calibration area to form the reflected light. At the second position, the detection light passes through the detection area to reach the object to be detected, and is reflected by the object to be detected to form the reflected light.

[0052] In the technical solution of the present invention, by driving the movable member 200 to move relative to the mounting base 100, the position of the calibration area and the detection area of ​​the movable member 200 relative to the transmitting device 710 can be changed. When the movable member 200 moves to the first position, the parameters of the detection device can be calibrated, and when the movable member 200 moves to the second position, the object to be detected can be detected. That is, only by driving the movable member 200 to move, the optical detection device can be switched between the calibration state and the detection state, without disassembling related components, and the operation is very convenient, which is conducive to improving the detection efficiency.

[0053] Specifically, in the first position, the calibration area can correspond to the optical path setting of the transmitting device 710, and the calibration area is provided with a specific material or a specific pattern. If the parameters of the transmitting device 710 meet the requirements, the calibration area can reflect the detection light to form a preset light after receiving it. Therefore, by analyzing the reflected light received by the receiving device 720, the parameters of the transmitting device 710 can be calibrated. When the reflected light deviates from the preset light, the parameters of the transmitting device 710 are adjusted until the deviation between the two is within the allowable error range. In the second position, the detection area can correspond to the optical path setting of the transmitting device 710. The detection area can be transparent, and the detection light passes through the detection area to reach the object to be detected. The detection area can also be opaque, and the detection light reaches the object to be detected after being reflected by the detection area. In this way, the detection light can be emitted to the detection object after passing through the detection area, and the receiving device 720 is used to receive the reflected light reflected by the object to be detected. At this time, the reflected light carries the parameter information of the object to be detected. Furthermore, in the technical solution of the present invention, the detection process is performed after the transmitter 710 is calibrated and qualified, thereby eliminating the parameter error of the equipment and facilitating the accuracy of the detection data of the object to be detected.

[0054] In one embodiment, if Figure 5As shown, the calibration area is provided with a first mounting groove 203, and the first mounting groove 203 is used to install the calibration plate 210; the detection area is provided with a light-transmitting hole 204, and the peripheral side of the light-transmitting hole 204 is provided with a second mounting groove 205, and the second mounting groove 205 is used to install the protective film 220. In this way, the movable part 200 can be set as a standard part, corresponding to different optical detection devices, and different calibration plates 210 can be adaptively installed in the first mounting groove 203, and different protective films 220 can be installed in the second mounting groove 205, which is conducive to improving the manufacturing standardization of optical detection devices. Among them, the outer periphery of the protective film 220 has a hard structure, which is installed in the second mounting groove 205 through the hard structure, which can improve the convenience of assembling the protective film 220. In addition, the calibration plate 210 and the protective film 220 can be engaged in the corresponding mounting grooves, so that the calibration plate 210 and the protective film 220 are detachable relative to the movable part 200. Different calibration plates 210 and protective films 220 can be replaced to meet different calibration requirements or detection requirements. Of course, in other embodiments, the calibration area of ​​the movable part 200 can be set to a specific material, the detection area can be set to a light-transmitting material, the movable part can be integrally formed with a calibration area of ​​a specific material and a detection area of ​​a light-transmitting material, or, after the movable part 200 is formed, a specific pattern can be processed in the calibration area.

[0055] Please refer to Figure 6 and Figure 7 , Figure 6 2 is a cross-sectional schematic diagram of the movable member 200 being driven to the first position by the first driving device 400. At this time, the calibration plate 210 is directly below the transmitting device 710. The detection light emitted by the detection device 710 reaches the calibration plate 210 and is reflected. The reflected light is projected toward the receiving device 720. Figure 7 It is a cross-sectional schematic diagram of the movable part 200 being driven to the second position by the first driving device 400. At this time, the protective film 220 is directly below the transmitting device 710. The detection light emitted by the detection device 710 passes through the protective film 220 and is projected toward the detection object. After reaching the object to be detected, the detection light formed by reflection is projected toward the receiving device 720.

[0056] In one embodiment, please refer to Figure 1 , Figure 2 and Figure 5The mounting base 100 includes a base plate 110 and a fixing plate 120. The fixing plate 120 is disposed on one side of the base plate 110, and a slide groove 121 is formed between the fixing plate 120 and the base plate 110. The movable member 200 can be slidably and retractably inserted into the slide groove 121. It can be understood that the movable member 200 can slide in the slide groove 121 to switch between the first position and the second position, and the movable member 200 can be pulled out from the slide groove 121, so as to facilitate the replacement of the movable member 200, or the replacement of the calibration plate 210 and the protective film 220 on the movable member 200.

[0057] Furthermore, in this embodiment, if Figure 5 As shown, the slide groove 121 is formed with a drawing opening 122 opened along the first direction y, the movable member 200 is provided with a first through hole 202 on one side close to the drawing opening 122, and the fixed plate 120 is provided with a second avoidance opening 123 corresponding to the first through hole 202. In this way, when the movable member 200 is drawn, the finger can be inserted into the first through hole 202 through the second avoidance opening 123, so that the operator can hold the movable member 200 stably and it is convenient for the operator to apply force. When installing the movable member 200, the operator can also conveniently hold the first through hole 202, and under the avoidance of the second avoidance opening 123, it can be ensured that the movable member 200 is installed in place in the slide groove 121. In addition, the slide groove 121 is provided with a draw-out opening 122 only on one side, and the other sides are closed by the fixed plate 120. The calibration area is located on the side of the detection area away from the draw-out opening 122. When the movable part 200 is in the first position, the first through hole 202 can be arranged relative to the second avoidance opening 123. At the same time, the transmitting device 710 and the receiving device 720 are also correspondingly arranged on the side away from the draw-out opening 122. After the optical detection device is finished working, the movable part 200 will return to the first position. In this way, when the optical detection device is on standby, the first through hole 202 is arranged relative to the second avoidance opening 123, which is convenient for the user to draw out the movable part 200. In addition, when the optical detection device is in the first position, after the detection light reaches the calibration area, it will be reflected to the receiving device 720, and will not pass through the calibration area. Therefore, when the optical detection device is on standby, the movable part 200 is placed in the first position, which can prevent the detection light from radiating outward, especially when the detection light is X-ray, which can protect the operator.

[0058] In one embodiment, please combine Figures 1 to 5The optical detection device also includes a transmission member 300 and a first driving device 400 drivingly connected to the transmission member 300, one of the transmission member 300 and the movable member 200 is provided with a plug-in portion 310, and the other is provided with a plug-in slot 201, the plug-in portion 310 is plugged into the plug-in slot 201; the movable member 200 is slidably connected to the mounting base 100 in a first direction y, the plug-in matching direction of the plug-in portion 310 and the plug-in slot 201 is a second direction z, and there is an angle between the first direction y and the second direction z, and the first driving device 400 drives the transmission member 300 to slide relative to the mounting base 100 along the first direction y to drive the movable member 200 to slide between the first position and the second position.

[0059] The first driving device 400 can be a motor or a cylinder. In an optional specific implementation, the second direction z is the distribution direction of the substrate 110 and the fixed plate 120, the first direction y and the second direction z are perpendicular or approximately perpendicular, and two transmission members 300 are respectively connected to each other on both sides of the first driving device 400. A guide rod 130 extending along the first direction y is also provided on the substrate 110. The first driving device 400 is sleeved on the guide rod 130. The first driving device 400 moves along the guide rod 130, which can drive the two transmission members 300 to slide relative to the substrate 110 along the first direction y. When the transmission member 300 slides relative to the substrate 110 along the first direction y, due to the plug-in fit between the plug-in portion 310 and the plug-in slot 201, the movable member 200 will be driven in the first direction y, and thus slide in the slide slot 121 along the first direction y, so as to be able to switch between the first position and the second position. When the transmission member 300 is driven to reciprocate, the movable member 200 will also slide back and forth between the first position and the second position. Of course, in other embodiments, the output shaft of the driving device may be fixedly connected with a gear, and the movable member 200 may be provided with a rack meshing with the gear, and the gear may be driven to rotate by the driving device, thereby driving the movable member 200 to slide.

[0060] Furthermore, in this embodiment, if Figure 1 , Figure 2 and Figure 5As shown, a fixing plate 120 is installed on one side of the base plate 110, and the first driving device 400 and the transmission member 300 are installed on the other side. The base plate 110 is provided with a first avoidance opening 111 relative to the slide slot 121, the plug-in portion 310 is provided on the transmission member 300, and the plug-in slot 201 is provided on the movable member 200. The plug-in portion 310 passes through the first avoidance opening 111 and is plugged into the plug-in slot 201. That is, the movable member 200 and the first driving device 400 are installed on opposite sides of the base plate 110, and the plug-in portion 310 is inserted into the plug-in slot 201 through the first avoidance opening 111. At the same time, the plug-in portion 310 is slidably connected to the first avoidance opening 111 in the first direction y, so as to guide the plug-in portion 310 to move in the first direction y through the first avoidance opening 111, thereby ensuring the stability of the movement of the plug-in portion 310, so as to make the movable member 200 slide smoothly. In addition, the transmitting device 710 and the detecting device are also correspondingly arranged on one side of the first driving device 400. At the same time, the substrate 110 is provided with avoidance openings corresponding to the positions of the transmitting device 710 and the receiving device 720 to avoid the propagation optical path of the detection light and the reflected light. The object to be detected is located on the side of the fixed plate 120 away from the substrate 110. The fixed plate 120 is also provided with a second through hole 124. When the movable part 200 is in the second position, the second through hole 124 and the protective film 220 are opposite to each other for the detection light to pass through, so that the detection light can reach the object to be detected. Of course, in other embodiments, it is also possible that the above-mentioned components are all arranged on the same side of the substrate 110, and the avoidance structures of the fixed plate 120 and the substrate 110 are swapped.

[0061] Furthermore, in this embodiment, if Figure 2 and Figure 4As shown, the transmission member 300 can move relative to the first driving device 400 in the second direction z, so that the plug-in portion 310 can be movably plugged into the plug-in slot 201; after the plug-in portion 310 is separated from the plug-in slot 201, the movable member 200 can be separated from the mounting base 100 along the first direction y. When the movable member 200 needs to be pulled out, the transmission member 300 is driven to move in the second direction z in a direction away from the fixing plate 120, so that the plug-in portion 310 is pulled out from the notch of the plug-in slot 201, and the plug-in portion 310 and the plug-in slot 201 do not interfere with each other in the first direction y, and the movable member 200 can be pulled out from the draw-out opening 122. After the movable part 200 is replaced, or the calibration plate 210 and the protective film 220 on the movable part 200 are replaced, the movable part 200 is inserted into the slide groove 121 from the pull-out opening 122. When the movable part 200 is inserted into place, the plug-in groove 201 can be aligned with the plug-in part 310. At this time, the transmission part 300 is driven to move toward the direction close to the fixed plate 120, so that the plug-in part 310 can be reinserted into the plug-in groove 201. Thereafter, the plug-in part 310 and the plug-in groove 201 are stably plugged, so that the movable part 200 can slide along the first direction y driven by the transmission part 300.

[0062] Furthermore, in this embodiment, if Figure 2 and Figure 4 As shown, an elastic member 510 is connected between the transmission member 300 and the first driving device 400. Under the action of the elastic member 510, the plug-in portion 310 and the plug-in slot 201 can maintain a plug-in relationship. In this way, when the plug-in portion 310 is not subjected to external force in the second direction z, it can maintain a position plugged with the plug-in slot 201. When the first driving device 400 drives the transmission member 300 to slide along the first direction y, the plug-in portion 310 can stably and continuously drive the movable member 200 to slide in the slide slot 121; when the transmission member 300 is subjected to external force, it can overcome the action of the elastic member 510, and the plug-in portion 310 can be disengaged from the plug-in slot 201, so that the movable member 200 can be drawn out of the slide slot 121. Of course, in other embodiments, the transmission member 300 may cooperate with the slot of the first drive device 400 through a buckle. When the transmission member 300 is buckled with the first drive device 400, the plug-in portion 310 can be correspondingly plugged into the plug-in slot 201. When the transmission member 300 is released from the buckle relationship with the first drive device 400, the buckle can be pulled out of the slot, and the plug-in portion 310 can be pulled out of the plug-in slot 201 simultaneously.

[0063] Furthermore, in this embodiment, if Figure 2 and Figure 4As shown, the optical detection device also includes a limiting boss 520 extending along the second direction z, and the transmission member 300 is movably connected to the first driving device 400 through the limiting boss 520. The elastic member 510 is configured as a spring sleeved on the limiting boss 520, and the two ends of the elastic member 510 are respectively abutted against the first driving device 400 and the transmission member 300. Among them, the first driving device 400 includes a first device body 410 and a connecting part 420 arranged on both sides of the device body. The power source is integrated on the first device body 410, and the connecting part 420 is used to cooperate with the transmission member 300. It can be that the limiting boss 520 is fixed to one of the transmission member 300 and the connecting part 420, and can be movably connected to the other in the second direction z. It can also be that the limiting boss 520 is movably connected to the transmission member 300 and the connecting part 420 in the second direction z at the same time to guide the transmission member 300 to move in the second direction z relative to the first driving device 400. The spring is arranged outside the limiting boss 520, so that the spring will not be misplaced and can stably act between the connecting part 420 and the transmission member 300. It can be understood that the first driving device 400 is fixed relative to the substrate 110 in the second direction z, and the first driving device 400 cooperates with the transmission member 300 through the limiting convex column 520 on the back side of the plug-in portion 310. The spring is arranged on the back side of the plug-in portion 310. When the plug-in portion 310 is plugged into the plug-in slot 201 and the plug-in portion 310 abuts against the bottom wall of the plug-in slot 201, the spring can be in a natural state or in a compressed state, so that the plug-in portion 310 can maintain the plug-in matching state with the plug-in slot 201. Of course, in other embodiments, the elastic member 510 can also be a spring sheet, elastic rubber or elastic silicone, and the elastic member 510 can also be located on the same side of the transmission member 300 as the plug-in portion 310.

[0064] Furthermore, in this embodiment, if Figure 1 , Figure 2 and Figure 4 As shown, the optical detection device further includes a second driving device 600, and the second driving device 600 is used to drive the transmission member 300 to move along the second direction z, so as to drive the plug-in portion 310 to disengage from the plug-in slot 201. Specifically, the second driving device 600 is used to drive the transmission member 300 to move in a direction away from the plug-in slot 201, so that the transmission member 300 overcomes the elastic force of the spring, drives the plug-in portion 310 to disengage from the plug-in slot 201, and the movable member 200 can be drawn out of the slide slot 121. Of course, in other embodiments, the operator can also drive the transmission member 300 manually.

[0065] Furthermore, in this embodiment, if Figure 2 and Figure 4As shown, the second driving device 600 is provided with a resisting portion 621, and the transmission member 300 is provided with a force-bearing portion 320, and the resisting portion 621 is located on a side of the force-bearing portion 320 close to the movable member 200. The second driving device 600 includes a second device body 610 and an action portion 620, the power source is integrated on the second device body 610, and the action portion 620 is provided with a force-bearing portion 320 for matching with the transmission member 300. In this way, when the second driving device 600 drives the pushing portion 621 to move toward the side away from the fixed plate 120, the pushing portion 621 can push the force-bearing portion 320, thereby driving the plug-in portion 310 to disengage from the plug-in slot 201, so that the movable part 200 can be pulled out of the slide slot 121; and when the plug-in portion 310 is plugged into the plug-in slot 201, the pushing portion 621 and the force-bearing portion 320 are spaced apart in the second direction z, which will not hinder the transmission member 300 from driving the movable part 200 to slide in the first manner, and at least one of the pushing portion 621 and the force-bearing portion 320 has a certain extension in the first direction y, so that after the pushing portion 621 and the force-bearing portion 320 move relative to each other in the first direction y, the force-bearing portion 320 can still have a portion relative to the pushing portion 621 for the pushing portion 621 to push against. In particular, the second drive device 600 can be configured as a single-acting cylinder. In the initial position, the push portion 621 and the force-bearing portion 320 are spaced apart in the second direction z. After the second drive device 600 is powered off, it can automatically return to the initial position. Of course, in other embodiments, the drive structure of the second drive device 600 can rotate relative to the transmission member 300. When the first drive device 400 drives the transmission member 300 to move in the first direction y, the second drive device 600 rotates to a position that does not interfere with the transmission member 300. When the movable member 200 needs to be pulled out, the second drive device 600 is rotated to a position that can cooperate with the transmission member 300 to drive the transmission member 300 to move in the second direction z.

[0066] In one embodiment, after the first drive device 400 is powered off, the movable member 200 can be reset to the first position. Specifically, the first drive device 400 can be set as a single-acting cylinder, or the first drive device 400 can be set as a motor or other cylinder, and is connected to the substrate 110 through a reset spring. In this way, after the first drive device 400 is powered off, the movable member 200 can be driven to reset to the first position to avoid the detection light from radiating outward. In particular, when the detection light is X-ray, in an emergency, the power supply of the first drive device 400 can be cut off to quickly reset the movable member 200 to the first position to avoid X-ray radiation outward and endanger human health. Of course, in other embodiments, a reset spring can also be connected between the movable member 200 and the mounting base 100. After the first drive device is powered off, the movable member 200 is subjected to the force applied by the reset spring, and can drive the first drive device 400 to reset to the first position together.

[0067] In one embodiment, a cover (not shown) is provided on the upper side of the substrate 110, and the transmitting device 710, the receiving device 720, the first driving device 400, the second driving device 600, etc. are all accommodated in the cover. In this way, the cover can protect the components and prevent dust, thereby increasing the life of the optical detection device in a dusty environment and reducing the maintenance frequency of the optical detection device. In particular, when the optical detection device is an X-ray detection device, the material of the cover can be set to a metal material, such as steel, to block the X-rays from radiating outward. In order to enhance the blocking effect of the cover on X-rays, a lead layer can also be set on the cover.

[0068] In one embodiment, please refer to Figures 1 to 7 The optical detection device is a reciprocating automatic locking and calibration X-ray detection device, including a substrate 110, an automatic locking device installed above the substrate 110, a reciprocating motion mechanism, an X-ray emitting device and an X-ray receiving device, and an X-ray calibration device installed below the substrate 110.

[0069] Among them, the reciprocating motion mechanism, that is, the first driving device 400, includes a horizontal motion cylinder as the first device body 410 and a conversion device of the connecting part 420; two automatic locking devices are provided, which are distributed on the opposite sides of the reciprocating motion mechanism in the x direction, and the automatic locking device includes a single-acting cylinder as the second device body 610, a cylinder conversion part as the acting part 620, a guide shaft as the limiting boss 520, a return spring as the elastic part 510, a guide block as the transmission part 300 and other components; the X-ray calibration device includes a fixed plate 120, a protective film 220, a calibration plate 210 and a calibration support plate as the movable part 200.

[0070] When the X-ray detection device is in standby mode, the automatic locking device and the reciprocating motion mechanism are at the origin position, the calibration support plate is at the calibration position, and the X-rays generated by the X-ray emitting device cannot radiate to the outside through the calibration plate. At this position, the X-ray receiving device can be opened for X-ray calibration.

[0071] When the X-ray test needs to be started, the solenoid valve needs to be used to control the horizontal motion cylinder to move the calibration support plate to the test position. At this time, the X-rays can be irradiated onto the object to be tested through the protective film to test the object to be tested.

[0072] After the test is completed, or when the equipment malfunctions, the horizontal motion cylinder will automatically reset and reset the calibration support plate to prevent X-ray radiation.

[0073] If the calibration plate 210 or the protective film 220 is to be replaced, the single-acting cylinder needs to be started, and the cylinder will rise, thereby overcoming the elastic force of the reset spring itself, moving along the guide shaft in the z direction, releasing the locking state of the calibration support plate, and then subsequent maintenance actions can be performed.

[0074] In summary, the X-ray detection device of this embodiment can realize the function of automatic X-ray calibration, automatically switch the calibration position and the test position, improve the calibration efficiency, and at the same time have a dustproof function, thereby increasing the life of the X-ray transmitting and receiving devices in a dusty environment and reducing the maintenance frequency. In addition, it also has the function of quickly replacing the protective film and the radiation protection function under special circumstances.
