The embodiment of the present application firstly provides an LED testing apparatus 20, which is used for testing an LED, for example: the LEDs are tested for electrical, optical, switching, color, thermal, or reliability characteristics, etc.

In the present embodiment, as shown in fig. 4, the LED testing apparatus 20 includes a mounting frame 21, a testing track 22, a feeding control mechanism 23, a testing blocking mechanism 24, and a feature testing mechanism; the mounting frame 21 is of a frame structure, and the mounting frame 21 is used as a mounting base body of the feeding control mechanism 23, the test blocking mechanism 24 and the characteristic test mechanism and plays a role in supporting all the mechanisms; the test track 22 is mounted on the mounting frame 21, the test track 22 is provided with a test chute 221 for the sliding of the LED, the test chute 221 extends obliquely downwards, and the test chute 221 is provided with a test position; it can be understood that the testing chute 221 extends obliquely downward, the testing track 22 also extends obliquely downward, and the width of the testing chute 221 is slightly larger than that of the LED, so that the LED flows in from the upper end opening of the testing chute 221 and spontaneously flows downward into the testing position under the action of self gravity, and then flows out from the lower end opening of the testing chute 221, and thus the LED can be conveyed and flowed without the help of other power elements, so that the whole LED testing device 20 has a simple structure, and is beneficial to reducing the manufacturing cost.

Further, the feeding control mechanism 23 is mounted on the mounting frame 21 and can block the LEDs and release the LEDs, so that a preset number of LEDs slide into the test positions, where the preset number is greater than or equal to 2; it can be understood that the feeding control mechanism 23 is located at the upstream of the testing position, the feeding control mechanism 23 prevents the excessive LEDs from sliding into the testing position by blocking the LEDs, and simultaneously, the preset number of LEDs is released to ensure that the preset number of LEDs enter the testing position for testing, wherein the preset number of LEDs may be two, three, four or more than five, and the specific number thereof may be selected according to actual needs, without limitation.

Furthermore, the test blocking mechanism 24 is mounted on the mounting frame 21 and located at a side of the test site and can block a preset number of LEDs in the test site; it can be understood that the test blocking mechanism 24 is located downstream of the feeding control mechanism 23, and the test blocking mechanism 24 prevents the LEDs from continuously sliding downward by blocking the plurality of LEDs released by the feeding control mechanism 23, so as to fix the LEDs in the test position, and facilitate the subsequent test of the performance test mechanism 25.

Furthermore, the performance testing mechanism 25 is mounted on the mounting frame 21 and located at a side of the testing position and is capable of electrically testing a predetermined number of LEDs in the testing position at the same time. It can be understood that the performance testing mechanism 25 is also located downstream of the feeding control mechanism 23, and the performance testing mechanism 25 can test different performances of the LED according to actual requirements, for example, the performance testing mechanism 25 can test the electrical performance of the LED, so that the probe of the performance testing mechanism 25 is in contact with the pin of the LED to turn on the testing circuit to obtain the electrical performance of the LED; in addition, the performance testing mechanism 25 adopts an LED testing mechanism with a mature technology on the market, and the detailed structure and working principle of the performance testing mechanism 25 are not described herein again.

In the LED testing device 20 of the embodiment of the present application, when in operation, the LEDs continuously enter the testing chute 221 from the upper end opening of the testing chute 221, and because the testing chute 221 extends obliquely downward, the LEDs spontaneously slide downward along the testing chute 221 under the action of their own gravity, when the LEDs slide to a certain position, the feeding control mechanism 23 blocks the LEDs and releases a preset number of LEDs, after the released multiple LEDs enter the testing position along the testing chute 221, the released multiple LEDs are blocked and fixed in the testing position by the testing blocking mechanism 24, and then the performance testing mechanism 25 simultaneously tests the multiple LEDs in the testing position, so that multiple tests of the LEDs are realized, and the testing efficiency and the production efficiency are improved; in addition, the LED testing device 20 can realize multiple tests of LEDs by the coordination of the feeding control mechanism 23, the testing blocking mechanism 24 and the performance testing mechanism 25; particularly, during each test, the feeding control mechanism 23 releases the preset number of LEDs to enter the test position, and blocks subsequent LEDs from entering the test position, so that the subsequent LEDs do not affect the LEDs entering the test position, thereby ensuring accurate test of the subsequent performance test mechanism 25, and meanwhile, the test blocking mechanism 24 blocks the LEDs in the fixed test position, ensuring that the positions of the LEDs are not deviated, and improving the test accuracy.

In another embodiment of the present application, as shown in fig. 5 and 6, the feeding control mechanism 23 of the LED testing apparatus 20 includes a first displacement driving member, a second displacement driving member, a feeding pressing shaft 232 and a feeding blocking shaft 233, wherein the first displacement driving member and the second displacement driving member are mounted on the mounting frame 21; the feeding pressing shaft 232 and the feeding blocking shaft 233 are arranged at intervals along the extending direction of the test chute 221; the first displacement driving member is in driving connection with the feeding blocking shaft 233, and can drive the feeding blocking shaft 233 to extend into the test chute 221 to block the LED, and can drive the feeding blocking shaft 233 to exit from the test chute 221 to release the LED; the second displacement driving member is in driving connection with the feeding pressing shaft 232, and can drive the feeding pressing shaft 232 to move towards the inside of the test chute 221 so as to press the LED, and can drive the feeding pressing shaft 232 to move back to the inside of the test chute 221 so as to release the LED.

For convenience of description, the LEDs are grouped, the number of LEDs in each group is a preset number, and the LEDs in each group are sequentially put into the test chute 221 for basic explanation. When the LED testing device 20 works specifically, before the first LED of each group slides into the feeding blocking shaft 233, the first displacement driving member drives the feeding blocking shaft 233 to be inserted into the testing chute 221, when the first LED slides to the feeding blocking shaft 233, the first LED abuts against the feeding blocking shaft 233 and cannot slide downward, and meanwhile, the following LED cannot slide downward when being blocked by the first LED; when the first LED of the next group abuts against the last LED of the previous group, the second displacement driving member drives the feeding pressing shaft 232 to move towards the test chute 221 and tightly press the first LED of the next group to fix the first LED of the next group, and then the first displacement driving member retreats from the test chute 221 at the feeding blocking shaft 233, so that the blocking of the first LED of the group is released, the LED of the group slides into the test position along the test chute 221 under the action of the self gravity, and the first LED of the next group cannot move in the test chute 221 due to the pressing and fixing action of the feeding pressing shaft 232, so that a preset number of LEDs are fed into the test position; after the group of LEDs enter the testing position, the first displacement driving member drives the feeding blocking shaft 233 to extend into the testing chute 221, and then the second displacement driving member drives the feeding pressing shaft 232 to move away from the next group of first LEDs, so that the pressing and fixing of the next group of first LEDs are released, the next group of LEDs can slide downwards along the testing chute 221 until the LEDs abut against the feeding blocking shaft 233, and continuous LED blocking and releasing can be realized by such reciprocating, so that continuous testing of the LED testing device 20 is realized.

As shown in fig. 4, 5 and 6, the mounting frame 21 is provided with a mounting platform 211 extending obliquely downward, the testing rail 22 is mounted on the mounting platform 211 and extends along the oblique direction of the mounting platform 211, the first and second displacement drivers are vertically mounted on the mounting platform 211, the feeding pressing shaft 232 and the feeding blocking shaft 233 are suspended above the testing chute 221, and the first and second displacement drivers respectively drive the feeding pressing shaft 232 and the feeding blocking shaft 233 to make reciprocating linear motion along the direction perpendicular to the mounting platform 211; wherein, pass through spring elastic connection between the drive end of first displacement driving piece and pan feeding compress shaft 232, when first displacement driving piece drive pan feeding compress shaft 232 compresses tightly LED like this, pan feeding compress shaft 232 can float under the spring action for pan feeding compress shaft 232 can not reduce the LED clamping ring with LED loss. Specifically, the first and second displacement drivers may be one component, namely, a first thin gas claw 231; of course, in other embodiments, the first displacement driving element and the second displacement driving element may also be other elements capable of driving the elements to reciprocate linearly, such as an air cylinder or a linear module.

Further, as shown in fig. 4, an air blowing mechanism 212 is further disposed on the mounting platform 211, and the air blowing mechanism 212 is disposed upstream of the feeding pressing shaft 232 and is used for blowing air to the LEDs in the test chute 221 to remove impurities such as dust on the LEDs, specifically, the air blowing mechanism 212 may be an air gun or other mechanism capable of blowing air.

In another embodiment of the present application, referring to fig. 6, the feeding control mechanism 23 of the LED testing apparatus 20 further includes a first correlation optical fiber 234, a second correlation optical fiber 235 and a third correlation optical fiber 236 disposed on the mounting frame 21, the first correlation optical fiber 234 is used for detecting whether there is an LED abutting against the feeding blocking shaft 233, the third correlation optical fiber 236 is used for detecting whether there is an LED at a position compressed by the feeding compressing shaft 232, the second correlation optical fiber 235 is used for detecting whether there is an LED at a position adjacent to the feeding blocking shaft 233 and compressed by the feeding compressing shaft, and the first correlation optical fiber 234, the second correlation optical fiber 235, the third correlation optical fiber 236, the first displacement driving member and the second displacement driving member are electrically connected.

Generally, the speed of the LEDs put into the test chute 221 is difficult to reach the same speed, and meanwhile, in the process that the LEDs slide in the test chute 221, the sliding speed of each LED is also difficult to reach the same speed, which results in that when the first LED of each group abuts against the feeding blocking shaft 233, and when the subsequent LEDs are blocked by the previous LED to stop sliding down, the time is uncertain, and when the first displacement driving member and the second displacement driving member are started, it is further uncertain that a preset number of LEDs enter the test position at each test position. At this time, the first correlation optical fiber 234, the second correlation optical fiber 235 and the third correlation optical fiber 236 are arranged to detect whether the first LED of each group is in place, whether the last LED of each group is in place and whether the first LED of the next group is in place respectively, so that when the first correlation optical fiber 234 and the second correlation optical fiber 235 detect that there is an LED, it indicates that there is a group of LEDs sliding in place, and when the third correlation optical fiber 236 detects that there is an LED, it indicates that the first LED of the next group also slides in place, at this time, the second displacement driving member is triggered to drive the feeding compressing shaft 232 to move, so as to accurately press on the first LED of the next group, and then the first displacement driving member is triggered to drive the feeding blocking shaft 233 to move out of the test chute 221, so that the group of LEDs can smoothly slide into the test position, so as to ensure that the test position can slide into the preset number of LEDs each time, and the LED test is ensured to be carried out smoothly.

Referring to fig. 6, each of the first correlation optical fiber 234, the second correlation optical fiber 235, and the third correlation optical fiber 236 includes an emitting end for emitting light and a receiving end for receiving light, the receiving end and the emitting end are respectively located at two opposite sides of the track, two opposite walls of the testing chute 221 are further provided with light passing holes, when there is no LED at a corresponding position in the testing chute 221, the light emitted from the emitting end passes through the light passing holes to irradiate the receiving end, and the receiving end receives the light to determine that there is no LED at the position; when the LEDs are arranged in the test sliding groove 221, light emitted by the receiving end is blocked by the LEDs, and at the moment, the receiving end cannot receive the light, so that the LEDs are determined to exist at the position, and thus, whether the LEDs exist can be determined. The transmitting end and the receiving end are over against the center of the LED, so that the accuracy of judging whether the LED exists is improved.

In another embodiment of the present application, as shown in fig. 7 and 8, the test stopping mechanism 24 of the LED testing apparatus 20 includes a third displacement driving element 241 and a first stopping plate 242, the third displacement driving element is mounted on the mounting frame 21, and a driving end of the third displacement driving element 241 is connected to the first stopping plate 242 and is used for driving the first stopping plate 242 to be inserted into the test chute 221 so as to stop a predetermined number of LEDs in a test position. During specific work, before the preset number of LEDs slide into the test position, the third displacement driving piece 241 drives the first blocking plate 242 to be inserted into the test sliding groove 221, so that after the preset number of LEDs slide to the test position, the preset number of LEDs cannot continuously slide along the test sliding groove 221 due to the first blocking plate 242, namely the preset number of LEDs are fixed in the test position, the performance testing mechanism 25 can be accurately butted with the LEDs in the test position, and the accuracy of performance testing is improved.

In another embodiment of the present application, as shown in fig. 7 and fig. 8, the test stopping mechanism 24 of the LED testing apparatus 20 is further provided to further include a moving driving assembly 243 and a second stopping plate 244, wherein the moving driving assembly 243 is mounted on the mounting frame 21, and the second stopping plate 244 and the first stopping plate 242 are arranged at intervals along the extending direction of the test chute 221; the driving end of the moving driving assembly 243 is connected to the second blocking plate 244 and can drive the second blocking plate 244 to be inserted into the test chute 221 and drive the second blocking plate 244 to move toward the first blocking plate 242, so as to push the LEDs in the test position to move toward the first blocking plate 242. During specific work, when a preset number of LEDs enter the test position and are blocked by the first blocking plate 242 and cannot slide down, the mobile driving assembly 243 drives the second blocking plate 244 to be inserted into the test chute 221, and then drives the second blocking plate 244 to move towards the first blocking plate 242, and in the process that the second blocking plate 244 moves towards the first blocking plate 242, the second blocking plate 244 can push the LEDs in the test position to approach towards the first blocking plate 242, so as to ensure that gaps between adjacent LEDs are within a certain range, thereby ensuring that each LED in the test position can be accurately butted with the performance testing mechanism 25, and ensuring the accuracy of the test. After the test is completed, the third displacement driving element 241 drives the first blocking plate 242 to exit the test chute 221, at this time, the LED after the test is completed slides out of the test position along the test chute 221 under the action of its own gravity and enters a subsequent process, and meanwhile, the movable driving element 243 drives the second blocking plate 244 to reset, so that the second blocking plate 244 exits from the test position, and it is ensured that the LED of the next test smoothly enters the test position.

Referring to fig. 4, 7 and 8, the movable driving assembly 243, the performance testing mechanism 25 and the third displacement driving member 241 are all located at a side of the testing track 22 and sequentially distributed from top to bottom along a length direction of the testing track 22, the second blocking plate 244 and the first blocking plate 242 are suspended right above the testing chute 221 and sequentially arranged at intervals from top to bottom along the length direction of the testing track 22, wherein the third displacement driving member 241 is vertically installed on the installation platform 211 and drives the first blocking plate 242 to reciprocate in a direction perpendicular to the installation platform 211, so as to drive the first blocking plate 242 to insert into or withdraw from the testing chute 221, and specifically, the third displacement member may be an air cylinder, a linear module or other components capable of driving the components to reciprocate.

Referring to fig. 4, 7 and 8, the moving driving assembly 243 includes a sixth displacement driving member 2431, a connecting frame 2432 and a seventh displacement driving member 2433, the seventh displacement driving member 2433 is mounted on the mounting platform 211 and is parallel to the testing chute 221, a driving end of the seventh displacement driving member 2433 is connected to the connecting frame 2432, the sixth displacement driving member 2431 is mounted on the connecting frame 2432 and is perpendicular to the mounting platform 211, and a driving end of the sixth displacement driving member 2431 is connected to the second blocking plate 244, wherein the sixth displacement driving member 2431 drives the second blocking plate 244 to reciprocate in a direction perpendicular to the mounting platform 211, so as to drive the second blocking plate 244 to be inserted into or withdrawn from the testing chute 221; the seventh displacement driving member 2433 drives the connecting frame 2432 and the second blocking plate 244 connected thereto to move linearly along the length direction of the testing chute 221, so as to push the LED at the testing position to move toward the first blocking plate 242; specifically, the sixth displacement driving member 2431 and the seventh displacement driving member 2433 can be cylinders, linear modules or other components capable of driving the components to perform reciprocating linear motion.

In another embodiment of the present application, as shown in fig. 4, 7 and 8, the test blocking mechanism 24 of the LED testing apparatus 20 further includes a detecting device 245 for sensing whether each LED in the test site is in place, wherein the detecting device 245 is electrically connected to the moving driving assembly 243 and the third displacement driving member 241. When the detecting device 245 senses that the number of the LEDs in the test position is the preset number, the detecting device 245 triggers the movable driving member to drive the second blocking plate 244 to be inserted into the test chute 221, and drive the second blocking plate 244 to move towards the first blocking plate 242, and push the LEDs to approach towards the first blocking plate 242, so as to adjust the gap between the LEDs within a certain range, so as to ensure that the performance testing mechanism 25 can accurately detect the performance of the LEDs; when the detecting device 245 senses that the number of the LEDs in the test position is greater than the preset number, that is, the redundant LED feeding control mechanism 23 is mistakenly released into the test position, the detecting device 245 triggers the third displacement driving member 241 to drive the first blocking plate 242 to exit the test chute 221, so that the LEDs in the test position directly slide out of the test chute 221 to perform material discharge processing, and thus, the redundant LEDs can be prevented from entering a subsequent process because the redundant LEDs are not detected by the performance testing mechanism 25.

As shown in fig. 8, the detecting device 245 includes a plurality of fourth opposite-incidence optical fibers distributed along the length direction of the test chute 221, and the number of the fourth opposite-incidence optical fibers is one more than the preset number, so that when the fourth opposite-incidence optical fibers of the preset number all detect LEDs and the last fourth opposite-incidence optical fiber does not detect LEDs, it can be detected that the number of the LEDs in the test position is exactly equal to the preset number; when the last fourth correlation optical fiber with the preset number detects the LEDs, the number of the LEDs entering the test position can be detected to be larger than the preset number, and therefore the number of the LEDs in the test position can be detected. The structure and the detection principle of the fourth correlation fiber sensing LED can refer to the structure and the principle of the first correlation fiber 234, which are not described herein again.

Specifically, the tested LEDs slide into the discharge control mechanism 26 along the testing chute 221, and the discharge control mechanism 26 controls the LEDs to be discharged into the subsequent process one by one, so that the LEDs discharged into the subsequent process are one by one, and the LEDs are prevented from being jammed by mutual extrusion in front of the LEDs; in addition, if a material distribution mechanism exists subsequently, the LEDs can be subjected to material distribution treatment according to different requirements.
