Description

Technical Field

[0001] This utility model relates to the field of LED manufacturing technology, and in particular to an LED bulb testing device and LED bulb production equipment. Background Technology

[0002] The final step in bulb production is to place the bulbs, which have undergone high and low pressure tests, onto the power testing station using a fixture. After the power test, qualified and unqualified bulbs are separated.

[0003] In the existing technology, the power testing station has multiple lamp holders, and each lamp holder has a bulb placement slot. When the fixture places the bulb in the bulb placement slot, due to factors such as the stability of the fixture and the size of the bulb placement slot, the ends of a small number of bulbs will be slightly tilted and stuck on the wall of the bulb placement slot. This prevents the ends of the bulbs from contacting the contacts in the bulb placement slot to complete the power-on test, requiring manual testing later. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an LED bulb detection device, which aims to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution:

Several embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this utility model will be more thorough and complete.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0029] Please see Figures 1 to 5The image shows an LED bulb testing device according to the first embodiment of this utility model, including a high and low pressure impact aging mechanism and a power testing mechanism arranged in production sequence. The high and low pressure impact aging mechanism includes a support frame 10, a bearing component 20 disposed on the support frame 10, and a clamping component 30 slidably connected to the support frame 10. The clamping component 30 includes two oppositely arranged clamping members 37 for clamping the bulb, and an ejection structure 36 disposed between the two clamping members 37. The power testing mechanism includes a support platform 50, a conveying component 40 located on the support platform 50, and a plurality of power testing components 60 disposed on the conveying component 40. The ejection structure 36 is used to squeeze the bulb toward the power testing component 60.

[0030] Understandably, this utility model provides an ejector structure 36 between the clamping members 37. After the clamping member 37 picks up the bulb on the bearing assembly 20, it slides along the support frame 10 to the power detection assembly 60 on the support platform 50. Then, the clamping member 37 is placed on the power detection assembly 60, and the ejector structure 36 is used to gently squeeze the bulb so that the end of the bulb can be straight in the power detection assembly 60 and contact the contact point. This solves the problem of the bulb not contacting the contact point in actual production and avoids the trouble of manual testing later.

[0031] Specifically, in this embodiment, the support frame 10 includes a frame bottom 11, a frame top 13 located above the frame bottom 11, and a frame post 12 connecting the frame bottom 11 and the frame top 13. The frame top 13 extends from the frame post 12 to above the power detection component 60. The bearing component 20 includes a bearing disk 21 rotatably disposed on the frame bottom 11 and a first bulb support seat 22 arranged in a ring on the bearing disk 21.

[0032] Understandably, the first bulb support 22 has an energized circuit and a first placement slot for placing the bulb end. The first placement slot is provided with contacts connected to the circuit, which can be used to perform high and low voltage tests on the bulb placed on it. After the high and low voltage tests are completed, the bulb is rotated to the clamping assembly 30 by the carrier plate 21 (driven by a motor, not shown in the figure).

[0033] Furthermore, the clamping assembly 30 also includes a transverse cylinder 31 disposed on the side of the frame top 13 facing the frame bottom 11, a sliding plate 32 connected to the extended end of the transverse cylinder 31, a vertical cylinder 33 connected to the sliding plate 32, a support plate 34 connected to the vertical cylinder 33, and a bidirectional cylinder 35 disposed on the support plate 34. The two clamping members 37 are respectively connected to the two extended ends of the bidirectional cylinder 35. The jaws 371 of the clamping members 37 are V-shaped.

[0034] Understandably, the clamping assembly 30 clamps two bulbs from the carrier plate 21 each time. When the bulbs need to be transported to the power detection assembly 60, the vertical cylinder 33 first drives the support plate 34 to lower the two clamping parts 37. When the jaws 371 of the clamping parts 37 reach the end of the bulb, the bidirectional cylinder 35 drives the two clamping parts 37 to move closer to each other and clamp the end of the bulb. Then the vertical cylinder 33 drives the bulb to rise. Next, the horizontal cylinder 31 drives the sliding plate 32 to move along with the bulb towards the power detection assembly 60. Then the vertical cylinder 33 lowers the bulb to the power detection assembly 60, realizing the transfer of the bulb. The V-shaped jaws 371 can stably clamp the end of the bulb.

[0035] Furthermore, the ejection structure 36 includes a telescopic rod disposed on the bidirectional cylinder 35. The telescopic rod includes a mother rod 361 connected to the bidirectional cylinder 35, a first sub-rod 362 slidably disposed in the mother rod 361, a second sub-rod 363 slidably disposed in the first sub-rod 362, a compression cap 365 disposed at the end of the second sub-rod 363, and a spring 364 disposed between the first sub-rod 362 and the second sub-rod 363. The ejection structure 36 also includes two connecting rods disposed on both sides of the first sub-rod 362. One end of the connecting rod is rotatably connected to the first sub-rod 362, and the other end is rotatably connected to the clamping member 37. The shape of the compression cap 365 is configured to match the shape of the bulb.

[0036] Understandably, the second bulb support 62 is similar to the first bulb support 22, having an energized circuit and a second placement slot 63 for placing the bulb end. The second placement slot 63 has contacts connected to the circuit, allowing power testing of the bulb placed thereon. When the bulb needs to be placed in the second placement slot 63, the vertical cylinder 33 drives the two clamping members 37 to lower the bulb end to the opening of the second placement slot 63. At this time, the compression cap 365 is not in contact with the bulb under the action of the two connecting rods. Then, the two clamping members 37 release the bulb, causing it to fall a short distance. During the opening of the clamp 37, under the action of the connecting rod, the first sub-rod 362 drives the second sub-rod 363 and the compression cap 365 to move downwards and contact the bulb. The clamp 37 continues to open. At this time, the reaction force of the bulb on the compression cap 365 causes the spring 364 to compress. The second sub-rod 363 moves upwards a short distance along the first sub-rod 362, which can prevent the compression cap 365 from crushing the bulb. It should be noted that the elastic potential of the spring 364 should not be too large to avoid crushing the bulb. It is only necessary to let the compression cap 365 slightly squeeze the bulb to make the end of the bulb correctly positioned in the second placement groove 63. The shape matching of the compression cap 365 and the bulb can increase the contact area and improve the uniformity of the force. It should be noted that when the clamping member 37 is lowering down while clamping the bulb in the first placement groove, the squeeze cap 365 will also squeeze the bulb because the two clamping members 37 are far apart from each other. However, this will not affect the clamping member 37's clamping of the bulb in the first placement groove.

[0037] Furthermore, the conveying assembly 40 includes two opposing gears 41 rotatably mounted on the support platform 50, a conveyor belt 43 meshing with the gears 41, and a sliding track 42 offset outside the conveyor belt 43, the sliding track 42 being fixedly connected to the support platform 50; the power detection assembly 60 includes a fixing block 61 connected to the conveyor belt 43, and a second bulb support 62 connected to the fixing block 61, the second bulb support 62 being slidably mounted on the sliding track 42.

[0038] Understandably, after the bulb is placed in the second placement slot 63, it will be automatically powered on for a power test. Then, the rotation of any gear 41 (driven by a motor, not shown in the figure) will drive the conveyor belt 43 to operate, which in turn drives the fixed block 61 together with the second bulb support 62 to operate, so that the second bulb support 62 slides orderly along the sliding track 42. After reaching the end, the qualified bulbs and unqualified bulbs can be sorted by the subsequent unloading mechanism.

[0039] In summary, the LED bulb detection device in the above embodiments of this utility model solves the problem of the bulb and the contact not making contact during actual production, and avoids the trouble of manual testing in the later stage.
