Detailed implementation manners

[0030] In order to make the objectives, technical solutions and advantages of the present utility model more clear and understandable, the following further describes the present utility model in detail with reference to specific embodiments and the accompanying drawings.

[0031] It should be noted that unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present utility model should have the ordinary meanings understood by those of ordinary skill in the field to which the present utility model belongs.

The terms such as "connected" or "coupled" are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. The terms such as "upper", "lower", "left", "right" are only used to represent relative positional relationships, and when the absolute position of the object being described changes, the relative positional relationship may also change accordingly.

[0032] With the rapid development of science and technology, optoelectronic devices are increasingly used in various fields. The sensitivity of optoelectronic devices is one of the important indicators to measure their performance, which directly affects their effect in practical applications.

[0033] Based on the background technology, the automatic detection method is to place the photoresistor with the pins facing downward in a suitable fixing seat, and then after moving to the detection point, move the two power-on pins of the detection module and finally contact the two pins of the photoresistor respectively, and connect the photoresistor to the detection circuit for detection. However, since the two pins of the photoresistor may be bent and deformed when placed on the fixing seat, the two power-on pins cannot be guaranteed to maintain good contact with the corresponding pins of the photoresistor at the same time when the two power-on pins overlap the pins after moving to the specified position, thereby causing poor contact, resulting in deviations in the detection effect or directly causing detection failures that require manual adjustment.

[0034] In order to solve the above technical problems, refer to Figure 1 The utility model provides a photoelectric device sensitivity detection device, comprising:

[0035] Testing station 1;

[0036] A light source module 2 is arranged on the top of the detection platform 1, and the light source module 2 includes a light source isolation box 201 for providing a detection light source;

[0037] The device conveying mechanism 3 includes a feeding mechanism 30 for conveying the photoelectric device 31 into the light source isolation box 201 for detection, the feeding mechanism 30 includes at least one feeding tray 302 for carrying the photoelectric device 31, the at least one feeding tray 302 is rotatably arranged on the detection table 1, and is partially located in the light source isolation box 201;

[0038] At least one detection module 4 is arranged in the light source isolation box 201 and corresponds one-to-one to the feeding tray 302. The detection module 4 includes two conductive plates 403 that are opened and closed. When the two conductive plates 403 are opened, the conductive plates 403 abut against the pins of the photoelectric device 31 located in the light source isolation box 201.

[0039] Specifically, the light source module 2 is arranged on the detection table 1 and includes a light source isolation box 201 for providing a detection light source. Among them, the light source isolation box 201 can isolate external light sources. The device conveying mechanism 3 includes a feeding mechanism 30 for conveying the optoelectronic device 31 into the light source isolation box 201 for detection. The feeding mechanism 30 includes at least one feeding tray 302 for carrying the optoelectronic device 31. At least one feeding tray 302 is rotatably arranged on the detection table 1 and partially located inside the light source isolation box 201; that is, it is equivalent to the feeding tray 302 penetrating through the side wall of the light source isolation box 201. In this way, when the feeding tray 302 rotates, the optoelectronic devices 31 at different positions arranged around the feeding tray 302 can be sent into the light source isolation box 201 for light source detection. Under the action of the light source isolation box 201, external light sources can be isolated, improving the detection accuracy and detection efficiency of the optoelectronic device 31. At least one detection module 4 is arranged inside the light source isolation box 201 and corresponds to the feeding tray 302 one by one. The detection module 4 includes two conductive plates 403 arranged in an openable and closable manner. When the two conductive plates 403 are opened, the conductive plates 403 are in contact with the pins of the optoelectronic device 31 located inside the light source isolation box 201. By opening the two conductive plates 403 of the detection module 4 to conduct with the pins of the optoelectronic device 31 and detecting the optoelectronic device 31 on the basis of the light source provided by the light source module 2, since the two conductive plates 403 are opened and closed to conduct with the optoelectronic device 31, the connection between the pins of the optoelectronic device 31 and the conductive plates 403 is made more stable, solving the problem of poor contact caused by the connection method of the pins when the optoelectronic device 31 is detected, resulting in deviation in the detection efficiency and reducing the detection efficiency.

[0040] Further, the optoelectronic device 31 in the present utility model can take a photoresistor as an example.

[0041] In some embodiments, as Figure 4 、 Figure 5 and Figure 6 shown, a plurality of fixing seats 303 are arranged in an array near the edge of the feeding tray 302. A placing groove 304 is provided on the fixing seat 303, and a jack 305 is provided in the placing groove 304. The optoelectronic device 31 is arranged in the placing groove 304, and the pins of the optoelectronic device 31 penetrate through the jack 305.

[0042] Specifically, the feeding tray 302 is circular, and a plurality of fixing seats 303 are arranged in a circular array around the edge of the top of the feeding tray 302. A placing groove 304 is provided on the top of the fixing seat 303, and a jack 305 is provided in the placing groove 304. Specifically, a cylindrical hole corresponding to the jack 305 is provided on the feeding tray 302. The optoelectronic device 31 is arranged in the placing groove 304, and the pins of the optoelectronic device 31 penetrate through the jack 305. At the same time, the pins of the optoelectronic device 31 penetrate through the cylindrical hole on the feeding tray 302, so that the optoelectronic device 31 is stably installed in the placing groove 304. Further, the fixing seat 303 is detachably arranged on the feeding tray 302, and the fixing seat 303 can be replaced on the feeding tray 302. When detecting optoelectronic devices 31 of different models, different models of fixing seats 303 can be replaced. Exemplarily, the fixing seat 303 can be fixed on the feeding tray 302 by screws. The fixing seat 303 can also be pasted on the feeding tray 302, which is not specifically limited in the present invention.

[0043] In some embodiments, as Figure 4 shown, the jack 305 has a shape with a wider upper part and a narrower lower part.

[0044] Specifically, the jack 305 has a wider upper part and a narrower lower part, so that it is convenient for the insertion of the optoelectronic device 31.

[0045] In some embodiments, as Figure 1 and Figure 2 shown, a feeding hole 5 is formed in the side wall of the light source isolation box 201, and the feeding tray 302 penetrates through the feeding hole 5.

[0046] Specifically, exemplarily, there are four feeding trays 302, and the four feeding trays 302 are arranged around the light source isolation box 201. Each feeding tray 302 penetrates through the side wall of the light source isolation box 201. Feeding holes 5 are provided on the four side walls of the light source isolation box 201. Among them, the width of the middle part of the feeding hole 5 matches the thickness of the feeding tray 302. As long as the feeding hole 5 can allow the feeding tray 302 to rotate, it is necessary to avoid too large a width, which may cause dust to enter the light source isolation box 201 and is difficult to clean.

[0047] In some embodiments, as Figure 1 and Figure 2 shown, access holes 51 are symmetrically provided at both ends of the feeding hole 5. The upper half of the access hole 51 is for the fixing seat 303 to pass through, and the lower half of the access hole 51 is for the pins of the optoelectronic device 31 to pass through.

[0048] Specifically, since the fixed seats 303 on the feeding tray 302 are arranged around the edge of the feeding tray 302, through holes 51 for the fixed seats 303 to pass through are provided at both ends of the feeding hole 5. The through holes 51 include an upper half and a lower half. The upper half is for the fixed seats 303 to pass through. Since the optoelectronic devices 31 are placed in the fixed seats 303, the pins of the optoelectronic devices 31 penetrate through the fixed seats 303 and extend below the feeding tray 302. Therefore, the lower half of the through holes 51 needs to allow the pins of the optoelectronic devices 31 to pass through, so as to ensure that the feeding tray 302 can stably feed the optoelectronic devices 31 into the light source isolation box 201 for light source detection.

[0049] In some embodiments, as Figure 7 and Figure 8 shown, the detection module 4 further includes a base 401, a support shaft 402, a vertical plate 404 and an electric push rod 405. The support shaft 402 and the vertical plate 404 are symmetrically arranged on the base 401. The electric push rod 405 is arranged on the vertical plate 404. The hinged ends of the two conductive plates 403 are rotatably arranged on the support shaft 402. Link rods 406 are respectively rotatably arranged on the adjacent side walls of the two conductive plates 403. The link rods 406 are hinged to the rod ends of the electric push rod 405. Wires 407 connected to the detector are respectively arranged on the two conductive plates 403.

[0050] Specifically, there are four detection modules 4, and each detection module 4 corresponds to a feeding tray 302 to detect the optoelectronic devices 31 on the feeding tray 302. The detection module 4 is arranged below the feeding tray 302. When the feeding tray 302 rotates, the optoelectronic devices 31 on the feeding tray 302 can pass through the detection module 4 and be in contact with it, and the detection module 4 can detect the optoelectronic devices 31. The detection module 4 further includes a base 401, a support shaft 402, a vertical plate 404, and an electric push rod 405. The base 401 is provided with a plurality of bolt holes, and the base 401 is fixed to the bottom of the light source isolation box 201 through the bolt holes. The support shaft 402 and the vertical plate 404 are symmetrically arranged on the top of the base 401. The electric push rod 405 is vertically arranged on the vertical plate 404, and the rod end of the electric push rod 405 faces the support shaft 402. The hinged ends of the two conductive plates 403 are rotatably arranged on the support shaft 402, that is, it can be understood that the two conductive plates 403 are rotatably arranged around the support shaft 402. Connecting rods 406 are respectively rotatably arranged on the adjacent side walls of the two conductive plates 403, that is, one end of the connecting rod 406 is hinged to the conductive plate 403, and the other end of the connecting rod 406 is hinged to the rod end of the electric push rod 405. In this way, when the rod end of the electric push rod 405 extends, it can push the two conductive plates 403 to open and close, so that the end faces of the conductive plates 403 are in contact with the pins of the optoelectronic device 31, making the connection between the optoelectronic device 31 and the conductive plates 403 more stable. Wires 407 connected to the detector are respectively arranged on the two conductive plates 403, that is, the conductive plates 403 are conducted with the detector. By conducting the pins of the optoelectronic device 31 with the conductive plates 403, in this way, a detection circuit is formed between the optoelectronic device 31 and the detector. After the optoelectronic device 31 receives the light source signal in the light source isolation box 201, the signal is sent to the detector through the conductive plate 403. The detector measures whether the light source signal meets the preset requirements. If it meets the preset requirements, it is considered that the optoelectronic device 31 meets the detection result. If it does not meet the preset requirements, it is considered that the optoelectronic device 31 does not meet the detection result. The detector will send a corresponding signal to the controller 10, and the controller 10 will control the electric push rod 405 and the drive motor 34 according to the received signal. Exemplarily, when receiving the signal that the optoelectronic device 31 does not meet the preset requirements, the controller 10 controls the electric push rod 405 to continue to extend, so that the two conductive plates 403 extend to the maximum, and the two conductive plates 403 will deform the pins of the optoelectronic device 31, enabling the inspection personnel to distinguish the unqualified optoelectronic devices 31.

[0051] In some embodiments, as Figure 2 and Figure 3 shown, a light source generator 202 is provided in the light source isolation box 201, and the light source generator 202 is arranged on the top of the light source isolation box 201.

[0052] Specifically, the light source generator 202 is provided with one and is arranged on the top of the light source isolation box 201. Using one light source generator 202 to provide a detection light source for the four feeding trays 302 saves resources and improves the detection efficiency at the same time.

[0053] In some embodiments, as Figure 3 shown, the light emitting direction of the light source generator 202 faces the detection table 1, and the position of the light emitting point of the light source generator 202 is higher than the end face of the feeding tray 302.

[0054] Specifically, the light source generator 202 is arranged on the top of the light source isolation box 201. Then, the light emitting direction of the light source generator 202 faces the detection table 1, and the position of the light emitting point of the light source generator 202 is higher than the end face of the feeding tray 302. In this way, it can irradiate on the feeding tray 302 and can better provide a detection light source for the optoelectronic device 31 on the feeding tray 302.

[0055] In some embodiments, as Figure 2 and Figure 3 shown, the device conveying mechanism 3 further includes a driving component. An installation cavity 11 is provided in the detection table 1. The driving component is arranged in the installation cavity 11. The driving component includes a first gear 33, a second gear 35 and a driving motor 34. The driving motor 34 is arranged in the middle of the installation cavity 11. The rotating shaft 301 of the driving motor 34 is connected to the second gear 35. The first gear 33 meshes with the second gear 35. The first gear 33 is connected to the feeding tray 302 through the rotating shaft 301.

[0056] Specifically, the device conveying mechanism 3 further includes a driving component. The driving component is used to drive the feeding tray 302 to rotate. The driving component includes a first gear 33, a second gear 35 and a driving motor 34. An installation cavity 11 for installing the driving component is provided in the detection table 1. The installation cavity 11 is of a U-shaped structure, and its driving motor 34 is installed at the lowest part of the U-shaped installation cavity 11 (that is Figure 2(inside the recessed groove), the rotating shaft 301 of the driving motor 34 is installed with a second gear 35, and the second gear 35 is rotatably arranged at the top of the installation cavity 11 and is driven by the rotating shaft 301 of the driving motor 34. In this way, the rotation of the second gear 35 is more stable. The first gears 33 include four, and the four first gears 33 are arranged equidistantly around the second gear 35. In this way, the four first gears 33 drive the four feeding trays 302. The first gears 33 are rotatably arranged at the top of the installation cavity 11 through the connecting shafts 32. The connecting shafts 32 are connected to the rotating shaft 301, and are connected to the feeding trays 302 through the connecting shafts 32 and the rotating shaft 301 to drive the feeding trays 302 to rotate. By driving the second gear 35 with the driving motor 34, the second gear 35 meshes with the first gears 33. The rotation of the second gear 35 drives the rotation of the first gears 33, and the rotation of the first gears 33 drives the rotation of the feeding trays 302, so as to send the optoelectronic devices 31 on the feeding trays 302 into the light source isolation box 201 for light source detection. By driving the feeding trays 302 with the driving assembly, the stable operation of the feeding trays 302 can be realized, and the detection efficiency can be improved.

[0057] In some embodiments, as Figure 1 、 Figure 2 and Figure 3 shown, a controller 10 is provided at the top of the light source isolation box 201, and the controller 10 is electrically connected to the electric push rod 405, the driving motor 34 and the detector respectively.

[0058] Specifically, the controller 10 is arranged at the top of the light source isolation box 201. In this way, it is convenient to adjust the parameters of the controller 10. The controller 10 is electrically connected to the electric push rod 405 and the driving motor 34 respectively, and controls the operation of the electric push rod 405 and the driving motor 34 according to the detection signal sent by the detector to ensure the stable operation and stable detection of the device.

[0059] It should be noted that the embodiments of the present invention can also be further described in the following ways:

[0060] To solve the problem that the pins of the optoelectronic device 31 are bent and deformed during detection, resulting in the inability to ensure that the energized pins for detection can fully contact the two pins of the optoelectronic device 31, thus causing poor contact and detection failure, a light source module 2 for isolating external light sources and providing detection light sources is installed on the upper part of the detection table 1. Four device transfer mechanisms capable of fixing and transporting the optoelectronic device 31 are also installed. Moreover, a detection module 4 for detecting the sensitivity of the optoelectronic device 31 and marking the optoelectronic devices 31 with abnormal detection results is provided on the upper part of the detection table 1. The detection module 4 mainly includes a base 401 fixed to the bottom of the detection table 1 by bolts. One end of the base 401 is provided with a support shaft 402, and two mutually articulated conductive plates 403 are rotatably installed on the support shaft 402. The other end of the base 401 is provided with a vertical plate 404, and an electric push rod 405 is installed at the top of the vertical plate 404. Two connecting rods 406 are articulated to the output shaft of the electric push rod 405, and one ends of the two connecting rods 406 are respectively articulated to the corresponding conductive plates 403.

[0061] The device transfer mechanism 3 includes a feeding mechanism 30 and a driving component. The feeding mechanism 30 can fix and rotate the pins of the optoelectronic device 31 for transportation. During the transportation process, the two pins are in hard contact with the two conical conductive plates 403 on the detection module 4, so as to ensure that the pins are in full contact with the energized pins to form a detection circuit. The light source is adjusted by the light source module 2 for detection. After the detection is qualified, the electric push rod 405 contracts to pull the two conductive plates 403 together through the connecting rods 406, facilitating the passage of the two pins of the optoelectronic device 31. When an abnormality is detected, the electric push rod 405 can also extend, enabling the two connecting rods 406 to push the two conductive plates 403 to open to a larger angle. Then, when the feeding tray 302 rotates to remove the optoelectronic device 31, due to the limitation of the two larger conductive plates 403, the two pins of the optoelectronic device 31 will be spread further apart, facilitating the subsequent staff to pick out the abnormal optoelectronic device 31. This solves the problem that simple lapping during the contact between the traditional energized pins and the conductive plates 403 may cause poor contact and detection failure, and further improves the detection quality and efficiency of the optoelectronic device 31.

[0062] Furthermore, as Figure 2 and Figure 3As shown in the figure, in order to ensure good stability during the detection of the optoelectronic device 31, the feeding mechanism 30 adopted in this solution mainly includes a rotating shaft 301 rotatably installed on the upper part of the detection table 1. A feeding tray 302 is installed at the upper end of the rotating shaft 301, and a fixing seat 303 is installed at the upper end of the feeding tray 302. A placement groove 304 for fixing the pins of the optoelectronic device 31 is formed on the surface of the fixing seat 303. The placement groove 304 includes a placement groove 304 (cylindrical groove) formed on the upper end surface of the fixing seat 303. Two funnel-shaped grooves (i.e., jacks 305) that are wider at the top and narrower at the bottom and are used for the pins of the optoelectronic device 31 to be inserted are formed in the placement groove 304. The two pins of the optoelectronic device 31 are respectively inserted into the corresponding placement grooves 304 for fixing, which is more convenient and faster for placement.

[0063] In order to enable the four feeding mechanisms 30 to convey synchronously, an installation cavity 11 is formed inside the upper end of the detection table 1 in the present utility model. The driving component is arranged in the installation cavity 11. The driving component includes a first gear 33, a second gear 35 and a driving motor 34. The driving motor 34 is arranged in the middle of the installation cavity 11. The rotating shaft 301 of the driving motor 34 is connected to the second gear 35. The first gear 33 meshes with the second gear 35. The first gear 33 is connected to the feeding tray 302 through the rotating shaft 301. Specifically, four connecting shafts 32 are rotatably installed in the installation cavity 11. One end of the connecting shaft 32 is connected to the bottom end of the rotating shaft 301. One ends of the four connecting shafts 32 are connected with a first gear 33. A driving motor 34 is also installed inside the driving cavity. The output shaft of the driving motor 34 is connected with a second gear 35. The second gear 35 rotates in cooperation with the four first gears 33. By driving the second gear 35 to rotate by the driving motor 34, the four rotating shafts 301 are driven to rotate through the four first gears 33 and the connecting shafts 32, driving the four feeding trays 302 to rotate synchronously in the same direction for feeding. The feeding is synchronous and unified, which is convenient for operation.

[0064] To solve the problem of interference from the external light environment to the light source module 2 during the detection of optoelectronic devices 31, the light source module 2 adopted in the present utility model mainly includes a light source isolation box 201 welded to the upper part of the detection table 1. Inside the upper end of the light source isolation box 201, a light source generator 202 is installed. The light source generator 202 is composed of a tunable laser and an optical modulator. Through holes 51 for the rotation of the feed tray 302 are provided on the outer walls of the four sides of the light source isolation box 201. The through holes 51 are used for the feed tray 302 to pass through. The through holes 51 include an upper half for the fixing seat 303 to pass through and a lower half for the bottom pins of the optoelectronic device 31 to pass through. The feed tray 302 of the feeding mechanism 30 rotates and conveys the optoelectronic device 31 into the interior of the light source isolation box 201, isolating most of the external light sources, and only providing light through the light source generator 202, reducing the interference of external light sources to the optoelectronic device 31. Moreover, the same light source module 2 can simultaneously provide illumination and regulation for the optoelectronic devices 31 on multiple feeding mechanisms 30, saving resources and improving the detection efficiency at the same time.

[0065] A controller 10 is installed on the upper part of the light source isolation box 201. The controller 10 includes four detectors connected to the main controller through wires 407 for detecting the data parameters of the optoelectronic device 31 under different illuminations. Two conductive plates 403 are respectively connected to the detectors through wires 407. The detectors transmit the data to the main controller through wires 407 and analyze and judge whether the optoelectronic device 31 is abnormal.

[0066] The present invention provides an optoelectronic device sensitivity detection device, which has at least the following beneficial effects:

[0067] 1. For the optoelectronic device sensitivity detection device, the device conveying mechanism 3 and the detection module 4 are provided. The device conveying mechanism 3 can fix and rotate the pins of the photoresistor during transportation. During the transportation process, the two pins are in hard contact with the two conical conductive plates 403 on the detection module 4, thus ensuring that the pins are in full contact with the energized pins to form a detection circuit, solving the problem that simple latching may cause poor contact and lead to detection failure when the traditional energized pins are in contact with the conductive plates 403, and further improving the detection quality and efficiency of the photoresistor.

[0068] 2. For the optoelectronic device sensitivity detection device, the opening angle of the two energized plates on the feeding mechanism 30 can be controlled by the electric push rod 405. When an abnormal photoresistor is detected, the two conductive plates 403 can be further opened. After the detection is completed, when the photoresistor is moved by the rotation of the feed tray 302, the two pins will be further separated by the two expanded energized plates. Therefore, when the abnormal photoresistor is removed from the isolation box, the staff can pick out the abnormal photoresistor according to the expanded angle of the photoresistor pins, which is more convenient to use.

[0069] 3. In the sensitivity detection device for an optoelectronic device, four sets of feeding mechanisms 30 are provided on the detection table 1, and corresponding detection mechanisms are also equipped. A detection light source is provided by the same light source module 2, which saves costs and greatly improves the detection efficiency.

[0070] The control mode of the present invention is automatically controlled by the controller 10. The control circuit of the controller 10 can be realized by simple programming of those skilled in the art. The provision of power also belongs to the common knowledge in the art. And the present invention mainly aims to protect mechanical devices, so the control mode and circuit connection of the present invention will not be explained in detail.
