[0084] The translation plate 030102 is fixed with a tray assembly 030105 at the top, and the translation cylinder 030101 is fixed at the bottom of the translation plate 030102. The slider of the translation cylinder 030101 is used for driving the translation plate 030102 and the tray assembly 030105 to move.

[0085] Referring to Figures 3 to 5 , Figure 6A and Figure 6BThe power-on assembly 0301 includes a tray assembly 030105 disposed on the top of the translation assembly and two rotary cylinders 030103. Specifically, the tray assembly 030105 and the two rotary cylinders 030103 are fixed to the translation plate 030102.
[0086] The two rotary cylinders 030103 are oppositely disposed, as shown in the figure. The two rotary cylinders 030103 are disposed on the left and right sides of the top surface of the translation plate 030102, and the tray assembly 030105 is disposed between the two rotary cylinders 030103. The rotary cylinders 030103 are used to press the tray assembly 030105 from the opposite sides, thereby achieving power supply to the circuit board 200. Figure 3
[0087] Each rotary cylinder 030103 has two magnetic sensors located at the upper and lower positions of the rotary cylinder 030103, which are used to detect and obtain the slider position electrical signal in the rotary cylinder 030103. The two sets of rotary cylinders 030103 have consistent structure and consistent action control.
[0088] As shown in the figures, Figure 3 and Figure 4 The power-on assembly 0301 includes a plurality of pressing blocks 030104, which are disposed one-to-one corresponding to the plurality of rotary cylinders 030103. The rotary cylinder 030103 includes a cylinder barrel 03010301 and a piston rod 03010303. The piston rod 03010303 is inserted into the hollow structure of the cylinder barrel 03010301. The bottom of the cylinder barrel 03010301 is fixedly connected to the translation plate 030102, and is used to move with the translation plate 030102 and the translation cylinder 030101. The top end of the piston rod 03010303 is exposed on the surface of the cylinder barrel 03010301. The top end of the piston rod 03010303 penetrates out of the cylinder barrel 03010301 from the top of the cylinder barrel 03010301, extends upward to the top side of the power-on assembly 0301, and is connected to the pressing block 030104. One end of the pressing block 030104 is connected to the piston rod 03010303, and the other end is away from the piston rod 03010303.
[0089] The pressing block 030104 is in the shape of a long strip. In the non-working state of the rotary cylinder 030103, the pressing block 030104 is located above the side of the tray assembly 030105. The end of the pressing block 030104 away from the piston rod 03010303 does not point to the tray assembly 030105, so as to avoid shielding the tray assembly 030105 and facilitate the feeding and discharging of the tray assembly 030105. Alternatively, in the non-working state of the rotary cylinder 030103, the extension direction of the pressing block 030104 is parallel to one side of the tray assembly 030105.

[0092] The tray 03010505 is used to carry the circuit board 200, and the tray 03010505 is detachably connected to the tray support plate 03010504.
[0093] As shown in Figure 6A The tray 03010505 includes a body 0301050501 and four rotating blocks 0301050502. The rotating blocks 0301050502 are arranged on the top surface of the body 0301050501, and the rotating blocks 0301050502 are pivotally connected to the body 0301050501.
[0094] Specifically, the rotating block 0301050502 includes a pressing member 030105050202 and a plug 030105050201. The pressing member 030105050202 is block-shaped, and the bottom surface of the pressing member 030105050202 is in contact with the top surface of the body 0301050501. The pressing member 030105050202 is formed with a first insertion hole penetrating through the thickness direction thereof, and correspondingly, the body 0301050501 is provided with a second insertion hole corresponding to the first insertion hole of the pressing member 030105050202.
[0095] The plug 030105050201 is columnar, and is arranged in the second insertion hole of the body 0301050501 through the first insertion hole of the pressing member 030105050202. Specifically, the plug 030105050201 is fixed in the second insertion hole of the body 0301050501.
[0096] The operator can manually rotate the pressing piece 030105050202, so that the pressing piece 030105050202 rotates 360° along the plug 030105050201, and the end of the pressing piece 030105050202 away from the plug 030105050201 can press the circuit board 200 to be tested, and the circuit board 200 is fixed during testing. Preferably, the four rotating blocks 0301050502 are arranged around the circuit board 200.
[0097] The four rotating blocks 0301050502 are distributed in pairs and can be pressed on the positive and negative plates of the circuit board 200, so that when loading and unloading are required, the pressing piece 030105050202 can be rotated to the blank position for loading and unloading, and when loading and unloading are completed, the pressing piece 030105050202 can be rotated to press the positive and negative plates of the circuit board 200, and after loading is completed, corresponding testing is performed.
[0098] Preferably, the top surface of the body 0301050501 is provided with a positioning groove in the area surrounded by the four rotating blocks 0301050502, and the circuit board 200 is accommodated in the positioning groove, and the shape of the positioning groove matches the circuit board 200.
[0099] The body 0301050501 has five holes penetrating through its thickness direction to facilitate accurate assembly of the positioning tray support plate 03010504 on the top surface.
[0100] The elastic member 03010501 is supported between the tray support plate 03010504 and the upper power probe plate 03010503. In this embodiment, the elastic member 03010501 is a flat head pin, which includes a pin and a sleeve. The pin is inserted into the radial inner side of the sleeve, the bottom of the pin elastically abuts against the bottom of the sleeve, and the top of the pin protrudes from the top of the sleeve. When the top of the pin is pressed, the pin can slide towards the bottom of the sleeve relative to the sleeve. The top of the pin elastically supports the tray support plate 03010504, and the sleeve is inlaid and fixed in the upper power probe plate 03010503. In this embodiment, the sleeve is inlaid and fixed in the through hole of the upper power probe plate 03010503.
[0101] The tray support plate 03010504 is provided with five positioning pins, which correspond one-to-one with the five holes on the body 0301050501, so as to achieve the effects of positioning and foolproofness. Four of the positioning pins are symmetrically arranged around the tray support plate 03010504, ensuring the positional accuracy of the tray 03010505. The remaining one is located on the lower left side of the tray support plate 03010504 and is used for foolproof design of the direction of the tray 03010505. When the tray 03010505 is placed in the wrong direction, it cannot be normally placed.
[0102] The power-on probe plate 03010503 includes a plurality of conductive probes 0301050301 extending to the tray 03010505. The number of conductive probes 0301050301 is a plurality, specifically, the power-on probe plate 03010503 is provided with 4 conductive probes 0301050301. Two groups of the 4 conductive probes 0301050301 are distributed on the power-on probe plate 03010503, and the conductive probes 0301050301 are just aligned with the positive and negative power-on copper-exposed areas of the circuit board 200.
[0103] Part of the conductive probes 0301050301 are electrically connected to the positive pole of the DC-DC power supply of the resolution test system 1000, and the other conductive probes 0301050301 are electrically connected to the negative pole of the DC-DC power supply of the resolution test system 1000. The top of the conductive probe 0301050301 is used to contact and electrically connect to the positive and negative poles of the circuit board 200 when the elastic member 03010501 is compressed, thereby supplying power to the circuit board 200. The tray support plate 03010504 is provided with a through hole penetrating the thickness direction thereof corresponding to the conductive probe 0301050301. The conductive probe 0301050301 is accommodated and penetrates the through hole, and is used to contact the circuit board 200 through the thickness direction of the tray 03010505.
[0104] As shown in Figure 3 With Figure 4 The rotating cylinder 030103 is used to press the tray 03010505 towards the power-on probe plate 03010503, reduce the size of the elastic member 03010501 between the tray support plate 03010504 and the power-on probe plate 03010503, until the top end of the conductive probe 0301050301 penetrates the tray support plate 03010504 and the tray 03010505, contacts the positive and negative poles of the circuit board 200, and supplies power to the circuit board 200. The elastic member 03010501 is used in the power-on assembly 0301, so that the circuit board 200 can be elastically protected when powered on, thereby avoiding damage.
[0105] When the pressing block 030104 does not contact the tray assembly 030105, the tray support plate 03010504 thereof will be subjected to the upward elastic force of the 4 elastic members 03010501, thereby separating the conductive probes 0301050301 on the power-on probe plate 03010503 and the circuit board 200 under test, so that the circuit board 200 loses power. The 4 elastic members 03010501 are respectively symmetrically fixed and distributed at the four corners of the power-on probe plate 03010503 for elastically supporting the tray support plate 03010504.
[0106] As shown in Figure 5As shown, the tray assembly includes a stepped screw 03010506 connected between the tray support plate 03010504 and the upper electrical probe plate 03010503, which is used to limit the maximum size between the tray support plate 03010504 and the upper electrical probe plate 03010503.
[0107] The stepped screw 03010506 includes a head and a rod connected to each other, the length of the rod is greater than the thickness of the upper electrical probe plate 03010503, the upper electrical probe plate 03010503 forms a limiting hole, the rod is fixedly connected to the tray support plate 03010504 through the limiting hole, and the outer diameter of the head is greater than the limiting hole. The head is located on the side of the upper electrical probe plate 03010503 away from the tray support plate 03010504.
[0108] In the case that the rotary cylinder 030103 does not contact the tray 03010505, the elastic member 03010501 is not compressed by the rotary cylinder 030103, the bottom surface of the upper electrical probe plate 03010503 abuts against the head, and the stepped screw 03010506 is used to limit the maximum size between the tray support plate 03010504 and the upper electrical probe plate 03010503.
[0109] During the process that the rotary cylinder 030103 presses the tray 03010505 towards the upper electrical probe plate 03010503, the gap between the bottom surface of the upper electrical probe plate 03010503 and the head gradually increases until the top end of the conductive probe 0301050301 contacts the positive and negative electrodes of the circuit board 200.
[0110] The tray assembly 030105 includes a guide rod bearing 03010502 arranged between the upper electrical probe plate 03010503 and the tray support plate 03010504 as a guide rail for the relative movement between the upper electrical probe plate 03010503 and the tray support plate 03010504, which ensures the high-precision linear movement between the upper electrical probe plate 03010503 and the tray support plate 03010504.
[0111] The number of guide rod bearings 03010502 in the tray assembly 030105 is two groups, the shaft sleeves of the two groups of guide rod bearings 03010502 are inlaid on the center line of the upper electrical probe plate 03010503 and are symmetrically arranged, and the guide rods of the two groups of guide rod bearings 03010502 are fixed on the tray support plate 03010504.

[0113] The activation assembly
[0114] Please refer to Figure 8 With Figure 9 The activation assembly 0303 comprises a light shield 030302 and an activation lamp assembly 030303 arranged on the top of the light shield 030302, and the activation lamp assembly 030303 comprises a three-bar cylinder 03030301 and an activation lamp 03030303 connected with each other.

The test box 03 comprises a control assembly 01, and the motor 030201 is fixed on a bottom plate 030501 and is used for rotating movement according to a pulse signal sent by the control assembly 01, so as to provide power for the up-down movement of the screw rod assembly 030202. The screw rod assembly 030202 is fixed on the surface of the bottom plate 030501 and a side plate 030502, and is a mechanism for converting the rotary movement into the up-down movement, so that the resolution plate 03020203 can accurately move up and down to reach a plurality of test positions corresponding to each other. When the capsule endoscope detects in the digestive tract, the close distance of the esophagus, the medium-long distance of the stomach, and the medium-close distance of the intestinal tract all need to obtain the best clear picture, so the lens 210 in the capsule endoscope needs to complete the resolution test at a plurality of test positions at different distances respectively.
[0125] The moving assembly 0302 comprises a drag chain 030203 and a drag chain fixing piece 03020206, and the drag chain fixing piece 03020206 is fixed on a sliding block 03020211 of the screw rod assembly 030202.

When the drag chain 030203 moves up and down with the screw rod assembly 030202, the wire will not be damaged.
[0126] As shown in Figure 11 , the screw rod assembly 030202 comprises a shaft coupling 03020201, a screw rod module 03020202, a resolution plate 03020203, an XY axis moving module 03020204, a drag chain fixing piece 03020206, a trigger 03020208, a first sensor 03020209, a second sensor 03020210 and a sliding block 03020211 connected with each other.
[0127] The screw rod module 03020202 is used for driving the sliding block 03020211 to move along the track of the screw rod module 03020202 under the drive of the motor 030201. As shown in Figure 11 , the screw rod module 03020202 comprises a sliding block fixing plate 03020207 arranged on the surface of the sliding block 03020211, the sliding block fixing plate 03020207 can move with the sliding block 03020211, and the sliding block fixing plate 03020207 can be used for connecting other components, so as to facilitate the fixation of other components on the sliding block 03020211.

[0129] The first sensor 03020209 and the second sensor 03020210 are located at the beginning and end of the lead screw module 03020202, respectively, for origin and extreme position detection. The first sensor 03020209 and the second sensor 03020210 are fixed on the C-shaped profile and simultaneously fixed to the side plate 030502 of the fixed support plate 0305.
[0130] When slider 03020211 moves trigger 03020208, triggering the first sensor 03020209 or the second sensor 03020210, control component 01 can obtain the corresponding signal and complete the corresponding action according to the corresponding logic.
[0131] Coupling 03020201 connects motor 030201 and lead screw module 03020202, so that the rotational power of motor 030201 can be transmitted to lead screw module 03020202.
[0132] The resolution board 03020203 may include a USAF1951 glass resolution board and LED lights. The LED lights in the resolution board 03020203 serve as a backlight to illuminate the USAF1951 glass resolution board. The LED lights can be the same type used in the circuit board under test 200. The resolution board 03020203 is fixed to the XY-axis moving module 03020204 on all four sides.
[0133] The XY axis moving module 03020204 is a precision adjustable standard moving module that can be adjusted in both the X and Y axes to ensure that the center of the resolution plate 03020203 is aligned with the center of the lens 210 under test.
[0134] like Figure 11 As shown, the lead screw assembly 030202 also includes a resolution plate support plate 03020205. One surface of the resolution plate support plate 03020205 is fixed to the XY axis moving module 03020204, and the other surface of the resolution plate support plate 03020205 is fixed to the slider fixing plate 03020207, so that the XY axis moving module 03020204 can move with the slider 03020211. The resolution plate support plate 03020205 is also equipped with reinforcing ribs on both sides to ensure that it does not wobble during movement.
[0135] One end of the chain fixing member 03020206 is fixed to the sliding block 03020211, and the other end is connected to the chain 030203, so as to ensure that the chain 030203 can move with the sliding block 03020211 of the lead screw module 03020202, thereby ensuring the protection of the internal wire during movement. Preferably, the chain fixing member 03020206 is fixed to the sliding block fixing plate 03020207.
[0136] Light source assembly
[0137] Please combine Figure 2 Referring to Figure 12 The test box 03 comprises at least one light source assembly 0304. The light source assembly 0304 has the characteristics of adjustable position and adjustable direction; according to the picture taken by the lens 210 in the actual test process, the uniformity of the light source is judged, and the light source effect is increased, reduced, moved and rotated to ensure that the lens 210 can effectively take normal images without overexposure, no reflection and other problems. At the same time, the LED lamp used in the light source assembly 0304 is the same as the LED lamp used in the circuit board 200, so as to ensure that the actual resolution of the lens 210 can be truly reflected during testing.
[0138] The light source assembly 0304 comprises a light source 030402 and two light source fixing blocks 030401 connected to each other, and the two light source fixing blocks 030401 are respectively connected to one end of the light source 030402.
[0139] Each light source fixing block 030401 forms a C-shaped via hole 03040102 and a circular via hole 03040103. The C-shaped via hole 03040102 is partially annular, or called crescent or waist-shaped. The circular via hole 03040103 is located at the center of the C-shaped via hole 03040102. The light source fixing block 030401 fixes the light source 030402 through the C-shaped via hole 03040102 and the circular via hole 03040103.
[0140] The two ends of the light source 030402 respectively have two protrusions 03040202, one of which is accommodated in the C-shaped via hole 03040102, and the other is accommodated in the circular via hole 03040103. When the light source 030402 is adjusted, the protrusion 03040202 accommodated in the circular via hole 03040103 can be rotated, and the protrusion 03040202 accommodated in the C-shaped via hole 03040102 can slide in the C-shaped via hole 03040102, thereby adjusting the light emitting direction of the light source assembly 0304, so that the light source can be supplemented in any direction according to the actual lighting effect.
[0141] The light source fixing block 030401 is fixed in any position in the test box 03 through the fixing hole 03040104, so that the light source can be supplemented at any position according to the actual effect.
[0142] Test process
[0143] In the default state of the resolution test system 1000, the elastic member 03010501 is in the popped-up state, and the power-on assembly 0301 does not supply power to the circuit board 200.
[0144] When the resolution test of the lens 210 is needed, the operator connects the compressed air and the 220V AC power supply to the resolution test system 1000, and triggers the power switch. After the control assembly 01 is powered on, it controls all devices to return to the original position.
[0145] The operator opens the door 0307 of the test box 03 to take out the tray 03010505 inside. The operator rotates the four groups of rotating blocks 0301050502 of the tray 03010505 to the blank position, then places the circuit board 200 in the corresponding position of the tray 03010505, and then rotates the four groups of rotating blocks 0301050502 to press on the circuit board 200, thereby fixing the circuit board 200. The operator opens the door 0307 of the test box 03, and places the processed tray 03010505 on the tray support plate 03010504. The holes of the tray 03010505 and the positioning pins of the tray support plate 03010504 correspond one by one, thereby completing the feeding operation. At this time, the lens 210 (left lens) to be tested is aligned with the center position of the resolution plate 03020203.
[0146] In the present application, the resolution test system 1000 includes a control assembly 01, which is arranged in an electric control box arranged at the bottom of the test box 03 and provides support for the structure of the test box 03. The control assembly 01 can include a programmable logic controller (PLC).
[0147] The resolution test system 1000 includes a client 02 in communication connection with the test box 03, which is used to receive and display the images taken by the lens 210. The client 02 can be a test computer or a tablet computer, a mobile phone, or other human-computer interaction devices. The client 02 is installed with corresponding test software (upper computer software), and the test software of the client 02 communicates with the wireless transceiver assembly in the control assembly 01 through a communication line to receive the images taken by the lens 210. The test software displays the decoded images on the display for human viewing and judgment. In some embodiments, the resolution test system 1000 does not include the client 02, and the images taken by the lens 210 are judged by the control assembly 01.
[0148] The control component 01 is configured to send an activation instruction. The control component 01 can send the activation instruction automatically according to the test process. Alternatively, as shown in FIG. 10, an activation button 1001 is arranged on the front panel of the test box 03, and an operator can trigger the activation button 1001 to send an activation signal to the control component 01, and the control component 01 sends an activation instruction according to the activation signal. The activation instruction is used to control at least the power-on component 0301 and the activation component 0303. Figures 1 to 2
[0149] The power-on component 0301 controls the rotary air cylinder 030103 to press the tray 03010505 according to the activation instruction, so as to supply power to the circuit board 200. The activation component 0303 controls the three-rod air cylinder 03030301 to drive the activation lamp 03030303 to move to the top side of the circuit board 200 and controls the activation lamp 03030303 to send infrared rays, thereby activating the lens 210, according to the activation instruction.
[0150] Specifically, the operator triggers the activation button 1001, and the control component 01 controls the electromagnetic valve to make the two sets of rotary air cylinders 030103 obtain compressed air for rotating downward movement to drive the two pressing blocks 030104 to rotate downward movement. When the two pressing blocks 030104 respectively contact the upper surfaces of the trays 03010505 and continue to move downward, the tray 03010505 and the tray support plate 03010504 continue to move downward against the upward elastic force of the four elastic members 03010501, until the tray support plate 03010504 and the power-on probe plate 03010503 are in contact with each other, and the conductive probes 0301050301 on the power-on probe plate 03010503 are in contact with the positive and negative electrodes of the circuit board 200 to be tested, so as to be powered on successfully. Preferably, as shown in FIG. 11, at this time, the rotary air cylinder 030103 reaches the maximum stroke, and the four elastic members 03010501 are also compressed to the maximum stroke. Figure 3 Figure 4
[0151] When the lower end magnetic sensor of the two sets of rotating air cylinders 030103 detects that the two sets of rotating air cylinders 030103 are in place, it transmits an electrical signal to the control assembly 01, and the control assembly 01 obtains a signal to control the electrically conductive probe 0301050301 on the upper power supply probe plate 03010503 to be powered on, and controls the electromagnetic valve to make the three-bar air cylinder 03030301 in the activation assembly 0303 obtain compressed air moving towards the upper power supply assembly 0301, and the three-bar air cylinder 03030301 drives the activation lamp 03030303 to move towards the upper power supply assembly 0301, and when the activation lamp 03030303 moves to the top side of the upper power supply assembly 0301, the front magnetic sensor of the three-bar air cylinder 03030301 detects that the three-bar air cylinder 03030301 is in place, and transmits an electrical signal to the control assembly 01.
[0152] After the control assembly 01 obtains the signal, it controls the activation lamp 03030303 to be powered on and normally work, emits specified infrared light to activate the circuit board 200, and starts timing. When the set time is reached, the control assembly 01 controls and disconnects the power supply of the activation lamp 03030303, and the activation lamp 03030303 stops emitting light after losing power; at the same time, the control assembly 01 controls the electromagnetic valve to make the three-bar air cylinder 03030301 obtain compressed air moving away from the upper power supply assembly 0301, and the three-bar air cylinder 03030301 drives the activation lamp 03030303 to move backward, and when the activation lamp 03030303 avoids the area directly above the circuit board 200, the rear magnetic sensor of the three-bar air cylinder 03030301 detects that the three-bar air cylinder 03030301 is in place, and transmits an electrical signal to the control assembly 01. After the control assembly 01 obtains the signal, it judges that the activation is completed and waits for the next instruction.
[0153] After the circuit board 200 under test is successfully activated, it emits an image code through a radio frequency signal, and the control assembly 01 includes a wireless transceiver board, which decodes the image code emitted by the circuit board 200 after obtaining it, and transmits it to the test software on the client 02 through a communication line and displays the real-time image taken by the lens 210 at this time.
[0154] The control assembly 01 is used to issue a test instruction, as shown in Figure 2 The surface of the test box 03 is provided with a test button 1002, and the operator observes that the circuit board 200 is activated and the image received by the client 02 is normal, and judges that the light resolution test needs to be performed, and triggers the test button 1002. When the test button 1002 is triggered, a test signal is sent to the control assembly 01, and the control assembly 01 issues a test instruction according to the test signal. In some embodiments, the control assembly 01 is used to judge whether the image taken by the lens 210 is normal, and if so, it automatically issues a test instruction. The test instruction is at least used to control the moving assembly 0302 or the activation assembly 0303.
[0155] The moving assembly 0302 is used to control the resolution plate 03020203 to move to one of the plurality of test positions according to the test instruction, and the lens 210 of the plurality of lenses 210 facing the resolution plate 03020203 takes a picture of the resolution plate 03020203; or the activating assembly 0303 is used to control the horizontal push cylinder 030305 to drive the human environment simulation pattern 030304 to move to the top side of the circuit board 200 according to the test instruction, and the plurality of lenses 210 take a picture of the human environment simulation pattern 030304.
[0156] Specifically, in the embodiment, when the operator observes that the client receives the image normally and judges that the optical resolution test needs to be performed, the test button 1002 is triggered.
[0157] When the control assembly 01 sends a control instruction after receiving the test signal, the motor 030201 in the moving assembly 0302 moves according to the control instruction. The motor 030201 drives the shaft coupling 03020201 to rotate and drives the screw rod of the screw rod module 03020202 to rotate. The screw rod in the screw rod module 03020202 drives the sliding block 03020211, the sliding block fixed plate 03020207, the resolution plate support plate 03020205, the XY axis moving module 03020204, and the resolution plate 03020203 to move up and down. When the resolution plate 03020203 moves to the first test position, the lens 210 facing the resolution plate 03020203 takes a picture of the resolution plate 03020203 at a long distance. The operator judges whether it is qualified by observing the image displayed on the test software of the client 02 and combining the test standard.
[0158] If it is qualified, the test button 1002 is triggered for the second time. After the control assembly 01 receives the test signal, the motor 030201 is controlled to move to the second test position again. The lens 210 facing the resolution plate 03020203 takes a picture of the resolution plate 03020203 at a medium distance. The operator judges whether it is qualified by observing the image displayed on the test software of the client 02 again and combining the test standard.
[0159] If it is qualified, the test button 1002 is triggered for the third time. After the control assembly 01 receives the test signal, the motor 030201 is controlled to move to the third test position again. The lens 210 facing the resolution plate 03020203 takes a picture of the resolution plate 03020203 at a short distance. The operator judges whether it is qualified by observing the image displayed on the test software of the client 02 and combining the test standard. At this time, the three test position judgments of the long distance, the medium distance, and the short distance of the first lens 210 in the circuit board 200 are completed.
[0160] If qualified, the fourth time trigger test button 1002, when the control component 01 gets the test signal, it sends a test command, and then controls the electromagnetic valve to make the translation cylinder 030101 in the upper power assembly 0301 get compressed air moving horizontally (in the embodiment of the application, it is specifically moving to the right), so that the second lens 210 of the circuit board 200 is aligned with the center position of the resolution board 03020203. When the right magnetic sensor of the translation cylinder 030101 detects that the translation cylinder 030101 is in place, it transmits an electrical signal to the control component 01, and the control component 01 gets the signal to determine that the switching of the lens 210 is completed, and the other lens 210 (the right lens) to be tested is aligned with the center position of the resolution board 03020203. The lens 210 to be tested takes a picture of the resolution board 03020203, and the control component 01 waits for the next instruction. When the operator observes that the right lens 210 image displayed on the test software on the client 02 can normally take a close-up image of the resolution board 03020203, the operator judges whether it is qualified according to the test standard.

[0162] If qualified, the seventh time trigger the test button 1002. The control component 01 gets the test signal to determine that the resolution test is qualified and needs to be tested for human environment simulation pattern, the control component 01 sends a test command, and then controls the backlight source in the environment simulation pattern assembly to be powered on to start normal light work to provide light source for the human environment simulation pattern 030304. At the same time, the electromagnetic valve is controlled to make the horizontal push cylinder 030305 in the activation assembly 0303 get compressed air moving to the upper power assembly 0301, and the horizontal push cylinder 030305 drives the light shield 030302 and the human environment simulation pattern 030304 to move forward. When the human environment simulation pattern 030304 is located directly above the circuit board 200, the front magnetic sensor of the horizontal push cylinder 030305 detects that the horizontal push cylinder 030305 is in place, and then transmits an electrical signal to the control component 01, and the control component 01 gets the signal to wait for the next instruction. Multiple lenses 210 take pictures of the human environment simulation pattern 030304, and the operator judges whether the multiple lenses 210 are qualified according to the images taken by the multiple lenses 210 in combination with the test standard.
[0163] If qualified, the eighth trigger test button 1002, control components 01 issued test instructions, in turn, control the backlight in the human environment simulation pattern 030304 off, while controlling the electromagnetic valve to make the horizontal push cylinder 030305 to obtain the compressed air moving away from the power components 0301 direction, horizontal push cylinder 030305 driven by the light shield 030302 and human environment simulation pattern 030304 to move away from the power components 0301 direction, when the human environment simulation pattern 030304 away from the top of the circuit board 200, the horizontal push cylinder 030305 of the rear magnetic sensor to detect the horizontal push cylinder 030305 to place, the electrical signal to the control component 01.
[0164] Control components 01 get signal again to control the electromagnetic valve to make the two groups of rotating cylinder 030103 of the power components 0301 to obtain the rotating upward movement of compressed air to drive the two blocks 030104 to rotate upward movement. When the two blocks 030104 upward movement, the tray 03010505 and tray support plate 03010504 will continue to move upward under the elastic force of the 4 elastic members 03010501, until the tray support plate 03010504 and the power probe plate 03010503 away from each other, the conductive probe 0301050301 on the power probe plate 03010503 also away from each other with the circuit board 200.
[0165] Preferably, at this time, the 4 elastic members 03010501 also rebound to the initial position, the piston rod of the rotating cylinder 030103 to the maximum stroke, the rotating cylinder 030103 stop working, the two groups of rotating cylinder 030103 of the upper end magnetic sensor to detect the two groups of rotating cylinder 030103 to place, the electrical signal to the control component 01, control components 01 get signal control power probe plate 03010503 on the conductive probe 0301050301 off.
[0166] The operator opens the door 0307 of the test box 03, takes out the tray 03010505 inside, and then rotates the 4 groups of rotating blocks 0301050502 in the tray 03010505 to the edge position of the tray 03010505, and then takes out the test completed circuit board 200 from the tray 03010505 and puts it into the corresponding qualified area position, and the test is completed; the same method is repeated to complete the test of the remaining to be tested circuit board 200 lens 210.
[0167] The control component 01 is configured to send a reset instruction. In this embodiment, the test box 03 is provided with a reset button 1003 on the surface. If the operator determines that the lens 210 is unqualified during the test process, the reset button 1003 can be triggered. When the reset button 1003 is triggered, a reset signal is sent to the control component 01, and the control component 01 sends a reset instruction according to the reset signal. Alternatively, in other embodiments, the control component 01 is configured to determine whether the lens 210 in the test meets the resolution requirement according to the image captured by the lens 210, and if not, the control component 01 sends a reset instruction.
[0168] The activation component 0303 and the moving component 0302 are configured to move to the corresponding original position according to the reset instruction, and the power-on component 0301 stops supplying power to the circuit board 200.
[0169] Specifically, if the operator determines that the lens 210 is unqualified during the test process, the reset button 1003 is triggered. After the control component 01 receives the reset signal, the control component 01 sends a reset instruction.
[0170] The control component 01 controls the motor 030201 in the moving component 0302 to drive the resolution plate 03020203 to move upward by using the reset instruction. When the trigger 03020208 triggers the first sensor 03020209, the control component 01 judges that it returns to the upper limit position. At this time, the control component 01 controls the motor 030201 to drive the resolution plate 03020203 to move downward by a specified distance to return to the original position by using the reset instruction. When the control component 01 obtains the signal that the moving component 0302 returns to the original position, it judges whether the rear magnetic sensor of the horizontal push air cylinder 030305 in the activation component 0303 triggers the electric signal. If not, the control component 01 controls the backlight source in the human body environment simulation pattern 030304 to lose power and turn off, and controls the electromagnetic valve to make the horizontal push air cylinder 030305 obtain compressed air for moving backward. The horizontal push air cylinder 030305 drives the light shield 030302 and the human body environment simulation pattern 030304 to move backward. When the rear magnetic sensor of the horizontal push air cylinder 030305 detects that the horizontal push air cylinder 030305 is in place, it transmits the electric signal to the control component 01. Finally, the control component 01 controls the electromagnetic valve to make the two groups of rotary air cylinders 030103 in the upper power component 0301 obtain compressed air for rotating upward, thereby driving the two pressing blocks 030104 to rotate upward. When the two pressing blocks 030104 gradually move upward, the tray 03010505 and the tray support plate 03010504 will continuously move upward under the elastic force of the four elastic members 03010501, until the tray support plate 03010504 and the upper power probe plate 03010503 move away from each other, and the conductive probe 0301050301 on the upper power probe plate 03010503 also moves away from the circuit board 200. At this time, the rotary air cylinder 030103 stops working. Preferably, when the rotary air cylinder 030103 stops working, it reaches the maximum stroke of the rotary air cylinder 030103, and the four elastic members 03010501 also rebound to return to the initial position. When the upper end magnetic sensor of the two groups of rotary air cylinders 030103 detects that the two groups of rotary air cylinders 030103 are in place, it transmits the electric signal to the control component 01. After the control component 01 obtains the signal, it controls the conductive probe 0301050301 on the upper power probe plate 03010503 to lose power.
[0171] The operator opens the door 0307 of the test box 03 to take out the tray 03010505 inside, then rotates the four groups of rotary blocks 0301050502 to the edge position of the tray 03010505, and then takes out the completed test circuit board 200 from the tray 03010505 and puts it into the corresponding unqualified area position.
[0172] The optical test of the circuit board 200 is the first test after focusing, and the unqualified rate of resolution power is high. In order to prevent wasting time, a progressive judgment is adopted. When any lens 210 appears unqualified at any test position, the resolution power test system 1000 can stop testing in time by using a reset instruction, and quickly and efficiently judge whether the resolution power of the focused lens 210 meets the requirements.
[0173] The resolution power test system 1000 provided by the embodiment of the application is used for optical resolution power test of the plurality of lenses 210 on the circuit board 200 of the double-lens capsule endoscope. The circuit board 200 is placed on the tray 03010505 by manual operation, and then the resolution power test system 1000 is activated by triggering the activation button 1001, and the control assembly 01 controls the resolution power board 03020203 to move accurately, so as to ensure that the resolution power of the plurality of lenses 210 at long distance, medium distance and short distance can be accurately photographed and judged.
