[0048] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0049] Embodiment 1

[0050] Please refer to Figure 1-Figure 15 A test device for LED lamp detection includes a lamp detection box 1 and an integrating sphere detection mechanism 3 arranged on one side of the lamp detection box 1. The integrating sphere detection mechanism 3 is composed of an integrating sphere body 301 and a light, color and electricity comprehensive detection box 302. The lamp detection box 1 is provided with a high and low temperature detection mechanism 2 for performing high and low temperature tests on LED lamps;

[0051] A feeding channel 4 is provided between the lamp inspection box 1 and the integrating sphere body 301, and a temperature control component is provided on the feeding channel 4 for controlling the temperature of the integrating sphere body 301. The lamp inspection box 1 is provided with a transfer mechanism 6 for transferring the LED lamps in the high and low temperature detection mechanism 2 to the feeding channel 4 for continuity detection.

[0052] In order to be able to perform real-time detection of LED lamps during the high and low temperature test of LED lamps in the present invention, a transfer mechanism 6 is added in the lamp detection box 1. By transferring the LED lamps in the high and low temperature detection mechanism 2 to the feeding channel 4, and then cooperating with the integrating sphere detection mechanism 3, a single LED lamp can be quickly detected. The transfer mechanism 6 sends the LED lamps into the feeding channel 4 and then sends the LED lamps to the high and low temperature detection mechanism 2. Repeating the above process can achieve continuous measurement of multiple LED lamps.

[0053] Further, the high and low temperature detection mechanism 2 includes a lifting plate 201 slidably arranged in the lamp detection box 1, the lifting plate 201 is provided with a driving motor 202, the output end of the driving motor 202 is provided with a rotating shaft 203 below the lifting plate 201, and a plurality of detection plates 204 are provided on the rotating shaft 203; a plurality of clamping parts 5 for clamping the LED lamp are slidably arranged on the detection plate 204, and a U-shaped limit strip 205 for cooperating with the clamping part 5 is also provided on the detection plate 204;

[0054] A guide plate 101 is provided in the lamp detection box 1 for cooperating with the detection plate 204 and guiding the clamping part 5 to be transferred into the feeding channel 4 , and two guide bars are provided on the guide plate 101 .

[0055] Furthermore, the lamp inspection box 1 is provided with two hydraulic cylinders for driving the lifting plate 201 to rise and fall. The height of the lifting plate 201 can be adjusted by the hydraulic cylinders, so that the height of the three inspection plates 204 can be adjusted. This adjustment method can be used in conjunction with the transfer mechanism 6, so that all LED lamps on the three inspection plates 204 can be sent into the feeding channel 4 for inspection.

[0056] Furthermore, the clamping part 5 includes a lower clamping member 501 and an upper clamping member 502, the upper clamping member 502 is provided with a plurality of sliding rods 503, the lower clamping member 501 is provided with a plurality of sliding grooves for matching the sliding rods 503, and the sliding rods 503 are sleeved with return springs 504 in the sliding grooves;

[0057] Two trapezoidal extrusion members 505 are slidably disposed on the upper clamping member 502 , and an extrusion spring 506 is disposed between the trapezoidal extrusion members 505 and the upper clamping member 502 .

[0058] Furthermore, a wire storage box is provided on the detection plate 204, and a winding roller is rotatably provided in the wire storage box, and flat spiral springs are provided at both ends of the winding roller, and the ends of the flat spiral springs are fixed to the inner wall of the wire storage box, and a power supply circuit is wound around the winding roller, and one end of the power supply circuit supplies power to the LED lamp, and the other end of the power supply circuit is electrically connected to the main power supply through a rotating electrical connector; when the LED lamp is placed in the clamping portion 5, the power supply circuit in the wire storage box is pulled out, and the power supply circuit is electrically connected to the input end of the LED lamp, because the entire clamping portion 5 and the LED lamp will move horizontally in the feeding channel 4, so when the clamping part 5 and the LED lamp move, the winding roller will unwind, so that the LED lamp can still be powered on when moving. When the clamping part 5 and the LED lamp return to the initial state, the flat spiral springs at both ends of the winding roller work, and the winding roller will rewind at this time, and rewind the released power supply line onto the winding roller, thereby ensuring the power-on state of the LED lamp during the entire movement of the LED lamp, which facilitates the rapid detection of the integrating sphere detection mechanism 3.

[0059] As can be seen from the above, the working principle of the high and low temperature detection mechanism 2 in the present invention is: put the LED lamp into the clamping part 5, clamp the LED lamp by the lower clamping piece 501 and the upper clamping piece 502 in the clamping part 5, and at the same time, slide the two trapezoidal extrusion pieces 505 set in the upper clamping piece 502 to further limit the LED lamp, so that the LED lamp can be clamped in the clamping part 5, and then place the combination of the clamping part 5 and the LED lamp on the detection board 204 in turn, and put the lower clamping piece 501 of the clamping part 5 into the U-shaped limit strip 205 on the detection board 204, so as to complete the placement of the LED lamp on the detection board 204;

[0060] Since a plurality of detection plates 204 are arranged on the rotating shaft 203, it is necessary to place the LED lamps on the three-layer detection plates 204 according to the above steps. After the driving motor 202 is started, the rotating shaft 203 can be driven to rotate, thereby driving the three-layer detection plates 204 to rotate. The purpose is to obtain a more uniform heating or cooling treatment. At the same time, the two hydraulic cylinders arranged on the lamp detection box 1 can adjust the height of the detection plates 204. When the upper end surface of one of the detection plates 204 coincides with the upper end surface of the guide plate 101, the LED lamps on the detection plate 204 can be transferred and detected by the transfer mechanism 6, and then cooperate with the work of the driving motor 202, so that all LED lamps on the detection plate 204 can be detected in real time. The setting of multiple layers of detection plates 204 and the adjustable height and angle of the detection plates 204 can not only improve the effect of high and low temperature detection of LED lamps, but also realize real-time detection of all LED lamps in the batch, greatly improving the versatility of the high and low temperature detection mechanism 2 and reducing the labor intensity of the operator.

[0061] Embodiment 2

[0062] Please refer to Figure 5-Figure 14 This embodiment is basically the same as the first embodiment. This embodiment is made on the basis of the first embodiment and has the same beneficial effects as the first embodiment. The same parts can be referred to each other and will not be described in detail here.

[0063] As a further technical solution of this embodiment, the transfer mechanism 6 includes a mounting shell 601 arranged on the inner wall of the lamp detection box 1, a rotating shaft 602 rotatably arranged on the mounting shell 601, and a rotating shell 603 arranged on the rotating shaft 602; the rotating shaft 602 is located on the lower side of the rotating shell 603, and the transfer mechanism 6 also includes a protective shell 610 arranged on the lamp detection box 1 for cooperating with the rotating shell 603 to rotate; when the rotating shell 603 rotates into the protective shell 610, the edge of the rotating shell 603 will not hinder the lifting and lowering of the detection plate 204;

[0064] A driving part for driving the rotating shaft 602 to rotate is disposed in the mounting shell 601, a transfer member 7 is slidably disposed on the rotating shell 603, and a driving assembly for driving the transfer member 7 to move is disposed in the rotating shell 603;

[0065] The driving part includes a worm 604 rotatably arranged in the mounting shell 601 and a first motor 605 arranged on the mounting shell 601, and the output end of the first motor 605 is fixedly arranged with the worm 604; the rotating shaft 602 is provided with a worm wheel 606 in the mounting shell 601, and the worm 604 and the worm wheel 606 are meshed with each other;

[0066] The driving assembly includes a screw rod 607 rotatably arranged in the rotating shell 603 and a second motor 608 arranged on the rotating shell 603. The output end of the second motor 608 is fixedly arranged with the screw rod 607. A threaded seat 609 is provided on the screw rod 607 through a threaded connection, and the threaded seat 609 is connected to the transfer member 7.

[0067] Further, the transfer member 7 includes a U-shaped mounting frame 701 slidably disposed on the rotating shell 603, a rotating rod 702 rotatably disposed in the U-shaped mounting frame 701, and a pushing member 703 disposed on the rotating rod 702;

[0068] Two sliding plates 704 are also provided on the U-shaped mounting frame 701, a sliding groove for cooperating with the sliding plates 704 is provided on the rotating shell 603, a threaded seat 609 is connected to one of the sliding plates 704, a third motor 705 is provided on the other sliding plate 704, a pulley 706 is provided at the output end of the third motor 705, a pulley 706 is also provided on the rotating rod 702, and the two pulleys 706 are driven by a synchronous belt;

[0069] Both sides of the lower clamping member 501 are provided with pushing grooves for cooperating with the pushing member 703.

[0070] The detection plate 204 , the guide plate 101 and the feeding channel 4 are all provided with strip-shaped through grooves for facilitating the use of the pusher 703 .

[0071] As can be seen from the above, the function of the transfer mechanism 6 in the present invention is specifically to transfer the combination of the clamping part 5 and the LED lamp on the detection board 204 to the feeding channel 4 for detection, and then transfer the combination of the clamping part 5 and the LED lamp from the feeding channel 4 to the initial position of the detection board 204 after the detection is completed, and repeat the above transfer process to realize real-time detection of multiple LED lamps on the detection board 204;

[0072] The working principle of the transfer mechanism 6 transferring the combination of the clamping part 5 and the LED lamp to the feeding channel 4 is as follows: when a certain detection plate 204 is lifted to be flush with the guide plate 101, and the clamping part 5 and the LED lamp on the detection plate 204 are facing the feeding channel 4, the transfer mechanism 6 can start working at this time; the driving part works, that is, the first motor 605 in the driving part works to drive the worm 604 to rotate. Since the worm 604 and the worm wheel 606 are meshed with each other, the rotation of the worm 604 can drive the rotating shaft 602 to rotate, and the rotating shaft 602 is located on the lower side of the rotating shell 603, so when the rotating shaft 602 rotates, the rotating shell 603 can rotate in the protective shell 610 and the lamp detection box 1;

[0073] When the rotating shell 603 rotates to a suitable position, that is, the center line of the rotating shell 603 is perpendicular to the center axis of the rotating shaft 203 and the distance between the rotating shell 603 and the rotating shaft 203 is the shortest (such as Figure 6 As shown), at this time, the driving assembly works, and the transfer member 7 is driven to work by the driving assembly; the driving assembly works, that is, the second motor 608 is powered on, and then drives the screw rod 607 to rotate, and the screw rod 607 rotates to further drive the threaded seat 609 to move. Since the threaded seat 609 is fixedly arranged with the sliding plate 704 on the U-shaped mounting frame 701, the second motor 608 works to drive the entire transfer member 7 to move on the rotating shell 603;

[0074] When the transfer member 7 moves as a whole, in order to drive the combination of the clamping part 5 and the LED lamp, it is also necessary to adjust the pushing member 703 in the transfer member 7, that is, the third motor 705 works, and the third motor 705 drives the pulley 706 to rotate, and the rotating rod 702 is also provided with a pulley 706, and the two pulleys 706 are driven by a synchronous belt, so that the third motor 705 can work to adjust the setting angle of the pushing member 703;

[0075] When the pusher 703 rotates to a vertical state, the driving assembly drives the pusher 703 to move toward one side of the feeding channel 4, and the pusher 703 moves toward the clamping portion 5, and then is stuck in the pushing groove of the lower clamping portion 501. As the screw rod 607 continues to rotate, the pusher 703 is driven to move the combination of the clamping portion 5 and the LED lamp into the feeding channel 4. After the threaded seat 609 moves to the extreme position at this angle, the angle of the pusher 703 is adjusted by the third motor 705, so that the pusher 703 changes from a vertical state to a horizontal state. The driving unit further works to drive the rotating shell 603 to rotate 180°, that is, the center line of the rotating shell 603 is perpendicular to the center axis of the rotating shaft 203 and the distance between the rotating shell 603 and the rotating shaft 203 is the farthest (such as Figure 7 As shown in the figure, when the rotating shell 603 is at this angle, the pushing member 703 rotates from the horizontal state to the vertical state, and the pushing member 703 continues to move toward one side of the feeding channel 4 under the drive of the second motor 608, and then continues to push the combination of the clamping part 5 and the LED lamp until the LED lamp is pushed to the limit position, at which time it can cooperate with the integrating sphere detection mechanism 3 for optical detection;

[0076] The above-mentioned part is the transfer of LED lamps to the feeding channel 4. Different from the traditional feeding process using electric push rods and linear screws, since the angle of the rotating shell 603 in the transfer mechanism 6 can be adjusted, and the pushing member 703 in direct contact with the clamping part 5 can also adjust the angle, this makes the entire transfer process more compact, can better integrate high and low temperature detection with optical detection, and the entire detection process can be carried out efficiently and automatically.

[0077] Furthermore, a light shielding plate 401 is slidably provided in the feeding channel 4, and a circular through hole is provided on the light shielding plate 401 for inserting the LED lamp;

[0078] The temperature control component includes an air inlet pipe and two air inlet shells 402 arranged on the feeding channel 4, the air inlet pipe is connected with the two air inlet shells 402, one end of the air inlet shell 402 is connected with the integrating sphere body 301, and a one-way valve is provided at the connection point, a push rod 403 is slidably provided in the air inlet shell 402, one end of the push rod 403 passes through the air inlet shell 402 and is fixedly connected with the light baffle 401, and a tension spring 404 is provided between the other end of the push rod 403 and the inner wall of the air inlet shell 402; normal temperature fresh air is introduced into the air inlet shell 402 through the air inlet pipe, and the normal temperature fresh air will enter the inside of the integrating sphere body 301, and the integrating sphere body 301 is correspondingly provided with an exhaust port, and the normal temperature fresh air can ensure the normal temperature of the integrating sphere body 301 during detection, and will not be affected by the temperature of the lamp detection box 1;

[0079] The working principle of the transfer mechanism 6 transferring the combination of the clamping part 5 and the LED lamp from the feeding channel 4 to the initial position on the detection plate 204 is as follows: when the clamping part 5 and the LED lamp move into the feeding channel 4, the LED lamp will first contact the light shielding plate 401, and then the clamping part 5 and the LED lamp will continue to move, and the head of the LED lamp will be inserted into the circular through hole in the light shielding plate 401. At this time, the shape formed by the light shielding plate 401 and the LED lamp will block the light source in the lamp detection box 1 from entering the integrating sphere body 301, thereby reducing the light source input error at the physical level;

[0080] When the combination of the clamping part 5 and the LED lamp needs to be restored to its initial state, a large amount of fresh air is introduced into the air inlet pipe, and the fresh air will enter the air inlet shell 402, thereby driving the push rod 403 to move. Since the push rod 403 and the light baffle 401 are fixedly arranged, the light baffle 401 pushes the clamping part 5 and the LED lamp to move into the lamp detection box 1 (at this time, the push member 703 is in a horizontal state). When the push rod 403 is driven by the fresh air to move to the extreme position, the introduction of fresh air is stopped, and the push rod 403 and the light baffle 401 are restored under the action of the tension spring 404. To the initial position, at this time, the combination of the clamping part 5 and the LED lamp is in the middle of the feeding channel 4, and the driving component is used to move the pushing member 703 between the clamping part 5 and the light blocking plate 401, and further rotate the pushing member 703 from the horizontal state to the horizontal state. Driven by the second motor 608, the pushing member 703 pushes the combination of the clamping part 5 and the LED lamp to move toward the detection plate 204 until the combination of the clamping part 5 and the LED lamp returns to the initial state on the detection plate 204, thereby completing the optical detection of an LED lamp.

[0081] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.
