[0032] The fixing mechanism also includes a fixed shell 4, which is fixedly arranged at the upper end of the detection shell 1. A movable opening 13 is provided in the middle of the fixed shell 4, and a limit rod 5 is correspondingly provided in the movable opening 13. A sliding opening 15 and a sliding opening 2 18 are symmetrically provided at the left and right ends of the fixed shell 4. The sliding opening 15 is connected to the movable opening 13 through the sliding opening 2 18. A limit block 20 is slidably provided in the sliding opening 2 18. A spring rod 2 19 is symmetrically provided on the upper and lower sides between the sliding opening 2 18 and the limit block 20. The tapered end of the limit block 20 corresponds to a plurality of limit grooves on the limit rod 5. The end of the limit block 20 away from the movable opening 13 is fixedly connected to the connecting rod 2 17. The connecting rod 2 17 is slidably connected to the sliding opening 15, and the connecting rod 2 17 is fixedly connected to the operating block 16.

[0033] Support blocks 23 are symmetrically provided on the left and right sides of the lower end of the fixing groove 9 and the lower end of the clamping block 21. Spring rods 24 are symmetrically provided on the upper and lower sides of the end of the support block 23 close to the support shaft 10. A connecting shaft 25 is rotatably provided between the spring rods 24 on the upper and lower sides, and the connecting shaft 25 is fixedly connected to the guide wheel 26.

[0034] The beneficial effects of the above technical solution are:

[0035] When fixing the organic electroluminescent display panel by the fixing mechanism, the organic electroluminescent display panel is placed in the fixing groove 9. Specifically, first, the distance between the lower end of the fixing groove 9 and the lower end of the clamping block 21 is adjusted according to the height of the organic electroluminescent display panel, and the operating block 16 is pulled. The operating block 16 drives the connecting rod 2 17 to move, and the connecting rod 2 17 drives the tapered end of the limit block 20 to disengage from the limit groove on the limit rod 5. The spring rod 2 19 is compressed, and then the control block 6 is used to drive the limit rod 5 to move up and down. The limit rod 5 passes The connecting rod 11 drives the clamping block 21 to move downward. After the distance between the lower end of the fixing groove 9 and the lower end of the clamping block 21 reaches the target distance, the operating block 16 is released. Under the elastic action of the spring rod 21, the tapered end of the limit block 20 is re-matched with the limit groove on the limit rod 5. At this time, the limit rod 5, the connecting rod 11 and the clamping block 21 connected thereto cannot move up and down, thereby achieving the purpose of adjusting the distance between the lower end of the fixing groove 9 and the lower end of the clamping block 21. Finally, the organic electroluminescent display panel is distributed on both sides of the lower end of the fixing groove 9. The guide wheels 26 and the guide wheels 26 distributed on the left and right sides of the lower end of the clamping block 21 are inserted in the middle. Since the guide wheels 26 are arranged in an arc shape, they can push the guide wheels 26 on the left and right sides to move in opposite directions. At the same time, the guide wheels 26 rotate to guide the organic electroluminescent display panel into the fixing groove 9, which also saves the force required to push the organic electroluminescent display panel. The spring rod 1 24 is compressed until the organic electroluminescent display panel is completely entered into the fixing groove 9. The guide wheels 26 distributed on the left and right sides of the lower end of the fixing groove 9 limit and fix the lower left and right ends of the organic electroluminescent display panel. The guide wheels 26 distributed on the left and right sides of the lower end of the clamping block 21 limit and fix the upper left and right ends of the organic electroluminescent display panel, and the lower end of the fixing groove 9 and the lower end of the clamping block 21 limit the upper and lower ends of the organic electroluminescent display panel, thereby completing the fixing effect of the organic electroluminescent display panel. The setting of the spring rod 1 24 can improve the stability of the organic electroluminescent display panel and prevent the organic electroluminescent display panel from shaking.

[0036] Example 3

[0037] On the basis of Example 2, Figure 1-Figure 5 As shown, the detection mechanism includes a mounting block 48, the right end of the mounting block 48 is fixedly connected to a plurality of thermal imaging cameras 38, and the plurality of thermal imaging cameras 38 are evenly spaced along the front-to-back direction. The upper end of the mounting block 48 is fixedly connected to the vertical section of the L-shaped block 39, and the horizontal end of the L-shaped block 39 is fixedly connected to the laser distance detector 41. The laser distance detector 41 is provided corresponding to the reflective block 22, and the reflective block 22 is fixedly provided at the left end of the clamping block 21. The laser distance detector 41 is electrically connected to the plurality of thermal imaging cameras 38 via a controller.

[0038] The left end of the mounting block 48 is fixedly connected to the mating block 43, and the mating block 43 is slidably connected to the sliding cavity 1 47. The sliding cavity 1 47 is provided on the front side of the right end of the threaded block 37. The rear side of the threaded block 37 is provided with threaded holes at both ends. The threaded holes are threadedly connected to the threaded sections of the threaded rod 33. The threaded rod 33 and the support shaft 10 are distributed left and right.

[0039] The upper and lower sides of the sliding cavity 47 are symmetrically connected with sliding grooves 44, and a connecting block 45 is slidably provided in the sliding groove 44. A spring rod 3 46 is fixed between the connecting block 45 and the sliding groove 44. The connecting block 45 is fixedly connected to the matching block 43. The left side of the sliding cavity 47 is connected to the matching hole 42. The matching hole 42 is set through the upper and lower ends of the front side of the threaded block 37. The matching hole 42 corresponds to the telescopic push rod 14, and the inclined end of the telescopic push rod 14 contacts the inclined end of the matching block 43.

[0040] The beneficial effects of the above technical solution are:

[0041] The thermal imaging camera 38 performs thermal imaging on the organic electroluminescent display panel. The arrangement of the plurality of thermal imaging cameras 38 makes the imaging area of ​​the plurality of thermal imaging cameras 38 in the front-to-back direction larger than the width of the organic electroluminescent display panel in the front-to-back direction. The threaded rod 33 rotates to drive the threaded block 37 to move up and down. The threaded block 37 drives the mounting block 48 to move up and down through the matching block 43. The mounting block 48 drives the plurality of thermal imaging cameras 38 and the laser distance detector 41 to move up and down, thereby facilitating the observation of the hot spots of the entire organic electroluminescent display panel through the thermal imaging camera 38 and the judgment of the distribution of the hot spots of the organic electroluminescent display panel. The laser distance detector 41 It is set that when the reflective block 22 moves up and down with the clamping block 21, so that the laser distance detector 41 cannot display the detection value, the thermal imaging camera 38 does not work until the laser distance detector 41 moves up and down with the thermal imaging camera 38 to the corresponding position of the reflective block 22. At this time, the laser emitted by the laser distance detector 41 can be reflected back by the reflective block 22, and the laser distance detector 41 can display the detection value, that is, the distance between the laser distance detector 41 and the reflective block 22 is detected. At this time, it indicates that the thermal imaging camera 38 has also moved to the corresponding position of the organic electroluminescent display panel, and the laser distance detector 41 controls the multiple thermal imaging cameras 38 through the controller to start working;

[0042] If it is necessary to maintain the thermal imaging camera 38 and the laser distance detector 41, the organic electroluminescent display panel is no longer placed in the fixing groove 9, and the telescopic push rod 14 is controlled to extend, and the threaded block 37 moves downward until the telescopic push rod 14 extends into the matching hole 42. Figure 2 and Figure 5The length of the middle telescopic push rod 14 and the matching hole 42 along the left and right directions can be set to be long enough, so that the length of the inclined end of the telescopic push rod 14 and the inclined end of the matching block 43 along the left and right directions is long enough. When the inclined end of the telescopic push rod 14 contacts the inclined end of the matching block 43, the matching block 43 is pushed to move to the right, and the matching block 43 drives the mounting block 48 to move to the right. The mounting block 48 drives several thermal imaging cameras 38 and the laser distance detector 41 to move to the right and enter the fixed groove 9, and then the several thermal imaging cameras 38 and the laser distance detector 41 are maintained through the working port 2. Only the working port 2 is set to maintain the components in the detection cavity 7, so as to avoid setting too many openings on the detection shell 1, which affects the heat insulation effect of the detection shell 1. When the thermal imaging camera 38 is working, the telescopic push rod 14 is controlled to retract, so that the telescopic push rod 14 cannot enter the matching hole 42, so as to avoid the left and right movement of the thermal imaging camera 38 affecting the detection of the heat dissipation performance of the organic electroluminescent display panel.

[0043] Example 4

[0044] On the basis of Example 3, Figure 1-Figure 5 As shown, the mating drive mechanism includes a motor 3, which is fixedly connected to a drive shaft. The drive shaft passes through the upper end of the detection housing 1, enters the drive cavity 40, and is fixedly connected to the disc 27. A guide rod 35 is provided at the lower end of the disc 27. The guide rod 35 corresponds to a plurality of guide grooves 36 on the outside of the left connecting disc 34. The cylindrical section of the threaded rod 33 passes through the upper end of the detection cavity 7, enters the drive cavity 40, and is fixedly connected to the left connecting disc 34.

[0045] The guide rod 35 also corresponds to the plurality of guide grooves 31 on the outside of the second right connecting disc 28. A mounting hole 29 is provided through the middle of the second right connecting disc 28. A toothed disc is fixed in the mounting hole 29. The inner ring of the toothed disc meshes with a gear 30. The gear 30 is fixedly connected to the fixed sleeve 12. The lower end of the second right connecting disc 28 is fixedly connected to a support sleeve 32. The support sleeve 32 is rotatably connected to the lower end of the drive chamber 40. The interior of the support sleeve 32 is provided with a movable hole for the fixed sleeve 12 to pass through.

[0046] The number of the plurality of guide grooves 1 36 and the number of the plurality of guide grooves 2 31 are both four, and the four guide grooves 1 36 are evenly distributed circumferentially outside the left connecting disk 1 34 , and the four guide grooves 2 31 are evenly distributed circumferentially outside the right connecting disk 2 28 .

[0047] The beneficial effects of the above technical solution are:

[0048] The disc 27, the guide rod 35, the left connecting disc 1 34 and the guide groove 1 36 constitute the groove wheel structure 1, and the disc 27, the guide rod 35, the right connecting disc 2 28 and the guide groove 2 31 constitute the groove wheel structure 2. When the driving mechanism works, the motor 3 drives the drive shaft to rotate, and the drive shaft drives the disc 27 to rotate. When the disc 27 rotates, it drives the guide rod 35 to rotate. The guide rod 35 cooperates with the guide groove 1 36 on the left connecting disc 1 34 to drive the left connecting disc 1 34 to rotate 90 degrees. When the left connecting disc 1 34 rotates, it drives the threaded rod 33 to rotate 90 degrees. After the threaded rod 33 rotates 90 degrees, the threaded block 37 moves downward a certain distance, so that several thermal imaging cameras 38 and the laser distance detector 41 move downward a certain distance. The downward movement distance of the thermal imaging camera 38 is its imaging area in the up and down directions. After the left connecting disc 1 34 rotates 90 degrees, the guide rod 35 disengages from the guide groove 1 36 until the guide rod 35 cooperates with the guide groove 2 31, which can drive the right connecting disc 2 28 to rotate 90 degrees. The right connecting disc 2 28 drives the gear disc to rotate 90 degrees. When the inner ring of the gear disc rotates 90 degrees, it can drive the gear 30 to rotate 180 degrees. When the gear 30 rotates 180 degrees, it can drive the fixing sleeve 12 to rotate 180 degrees. The fixing sleeve 12 drives the C-block 8 to rotate 180 degrees. During this process, the C-block 8 drives the clamping block 21 to rotate. The clamping block 21 drives the limit rod 5 to rotate through the connecting rod 11. The setting of the limit groove of the limit rod 5 makes the limit The tapered end of the block 20 can slide circumferentially along the limiting groove, so that the limiting rod 5 can rotate freely, thereby enabling the organic electroluminescent display panel to rotate 180 degrees, making it convenient to detect the heat dissipation performance of both the front and back sides of the organic electroluminescent display panel. This reciprocating motion achieves the purpose of intermittent rotation of the left connecting disk 1 34 and the right connecting disk 2 28. After the thermal imaging cameras 38 start working, they first perform thermal imaging on the front side of the organic electroluminescent display panel. As the organic electroluminescent display panel rotates 180 degrees, the back side of the organic electroluminescent display panel is thermally imaged. Then, the thermal imaging cameras 38 move downward a certain distance and continue to perform thermal imaging on the back side of the organic electroluminescent display panel. The optical display panel is rotated 180 degrees again, so that the thermal imaging cameras 38 perform thermal imaging on the front of the organic electroluminescent display panel. The imaging time of the thermal imaging camera 38 is the gap when the guide rod 35 is out of the fit of the guide groove 1 36 and does not fit with the guide groove 2 31 or the gap when the guide rod 35 is out of the fit of the guide groove 2 31 and does not fit with the guide groove 1 36. This reciprocating process allows the thermal imaging cameras 38 to perform all-round thermal imaging on the front and back of the organic electroluminescent display panel from top to bottom, thereby improving the reliability of the detection of the heat dissipation performance of the organic electroluminescent display panel. If the thermal imaging cameras 38 and the laser distance detector 41 are restored to their original positions, the motor 3 can be controlled to work in the reverse direction, in conjunction with the setting of the drive mechanism.The movement of the thermal imaging cameras 38 and the rotation of the organic electroluminescent display panel can be completed by controlling the motor 3 only, and the operation is simple and convenient.
