[0002] The LED filaments in LED filament lamps are fixed on the core columns in a series or parallel or series-parallel combination manner and are driven by an LED drive power supply. Existing LED filament lamps are mainly assembled from components such as an LED filament lamp body, a drive power supply, and a lamp head. During the production process of LED filament lamps, quality detection is required to ensure normal use in the later stage and avoid defective products.

[0003] The existing patent (Publication No.: CN215867045U) discloses a quality detection device for the production of LED filament lamps. Through the designed sponge block, it can provide protection during the detection of LED filament lamps, avoid the problem of LED filament lamps falling from the hands of testers and causing breakage, ensure the normal progress of production, and avoid the increase in production costs, and improve the deficiencies in the existing detection structure. During the implementation of this solution, it is found that the following problems exist in the prior art and have not been well solved:

[0004] During the detection process of this device, all rely on manual operation by staff. The speed of a single detection work is already relatively slow, and it is impossible to complete the detection when dealing with a large number of detection tasks. The detection efficiency is low, and during the detection process, staff need to hold the light bulb, which poses a great safety hazard. Summary of the Utility Model

[0006] The utility model provides a filament quality detection device, adopting the following technical scheme:

[0007] A filament quality detection device includes an operating table and an electric push rod.

Moreover, there is no need for the staff to manually support, and the detection work can be completed by pushing the fixed block, improving the detection efficiency. And the electric push rod drives the socket to automatically lift to complete the detection of the filament, with a high degree of detection safety.

[0012] Optionally, in the above filament quality detection device, the marking blocks are symmetrically distributed on both sides of the fixed block. The distance between the marking blocks is the same as the distance between the laser machines. The center of the fixed block and the center of the lifting block are on the same horizontal line above.

[0013] Through the above technical solution, it is convenient for the laser machine to irradiate above the marking block through the marking block, thereby completing the centering alignment work of the fixed block and the lifting block.

[0014] Optionally, in the above filament quality detection device, the side plate and the fixed block are integrally installed. The damping dampers are evenly and equidistantly distributed inside the side plate. The damping dampers and the clamping blocks are integrally installed. The clamping blocks and the side plate form a spring damping structure through the damping dampers.

[0016] Optionally, in the above filament quality detection device, the clamping block and the protective rubber are integrally installed. The protective rubber and the protective block are made of the same material. The protective blocks are semicircularly distributed at the center of the fixed block.

[0017] Through the above technical solution, it is convenient to cooperate the protective rubber with the protective block to limit and protect the bulb, preventing accidental damage caused by bumping during fixation.

[0018] Optionally, in the above filament quality detection device, the electric push rod and the lifting block form an integrated lifting structure. The protective blocks are symmetrically distributed on both sides of the lifting block. The length of the protective block is greater than the length of the filament. The center of the lifting block coincides with the center of the socket.

[0019] Through the above technical solution, it is convenient to protect the lifting block through the protection block, preventing it from squeezing the bulb too much in the descending position and causing damage.

[0020] To sum up, the utility model includes at least one of the following beneficial effects:

[0021] By arranging a linkage block and a fixed block above the operating table, and a three-jaw chuck structure is arranged inside the fixed block, the bulb and the filament inside it can be quickly limited and fixed. Then, during the detection process, the staff only needs to push the linkage block to complete the detection, without the staff manually grasping the bulb, reducing potential safety hazards;

[0022] By arranging an electric push rod and a lifting block above the operating table, the socket can be automatically lifted and lowered to detect the filament, improving the detection efficiency. And laser machines and protection blocks are arranged on both sides of the lifting block. On the one hand, it ensures that the lifting block can be quickly aligned with the fixed block, and on the other hand, it limits the lifting block to prevent it from descending too much and causing damage to the bulb.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0029] The following is a further detailed description of the present utility model in conjunction with the attached Figures 1-5 figures.

[0030] Please refer to the drawings in the specification Figures 1-5, An embodiment provided by the present utility model: A filament quality detection device, including an operation table 1 and an electric push rod 11. Above the operation table 1 is connected a sliding block 3, which drives the linkage block 2 to move, facilitating operation. Above the sliding block 3 is connected a linkage block 2, and above the linkage block 2 is connected a fixing block 4, which limits the position of the bulb through the fixing block 4, facilitating subsequent detection work. Above the fixing block 4 is connected a marking block 5, which facilitates alignment and improves the detection efficiency. At the center of the fixing block 4 is connected a protective block 6. Above the protective block 6 is provided a clamping block 9. Through the cooperation of the clamping block 9 and the side plate 7, the position-limiting and fixing work of the bulb is completed. Inside the clamping block 9 is connected a protective rubber 10, and outside the clamping block 9 is connected a shock damping 8. Outside the shock damping 8 is provided a side plate 7;

[0031] Below the electric push rod 11 is connected a lifting block 12. By driving the lifting block 12 to descend through the electric push rod 11, the socket 13 is automatically position-limited and fixed. At the center below the lifting block 12 is connected a socket 13, and on both sides below the lifting block 12 are connected laser machines 14, which are used for auxiliary alignment work. At the edge of the lifting block 12 is connected a protective block 15.

[0032] Refer to the accompanying drawings of the specification Figures 1-5 , The connection mode between the operation table 1 and the sliding block 3 is a sliding connection. The sliding blocks 3 are symmetrically distributed below the linkage block 2. The fixing blocks 4 are evenly and equidistantly distributed above the linkage block 2. By driving the linkage block 2 to move through the sliding block 3, the detection effect is improved, ensuring convenient use.

[0033] Refer to the accompanying drawings of the specification Figures 1-5 , On both sides of the fixing block 4 are symmetrically distributed marking blocks 5. The distance between the marking blocks 5 is the same as the distance between the laser machines 14. The center of the fixing block 4 and the center of the lifting block 12 are on the same horizontal line above. Through the marking blocks 5, the laser machines 14 can irradiate above the marking blocks 5, thus completing the centering alignment work between the fixing block 4 and the lifting block 12.

[0034] Refer to the accompanying drawings of the specification Figures 1-5 , The side plate 7 and the fixing block 4 are integrally installed. Inside the side plate 7 are evenly and equidistantly distributed shock dampings 8. The shock dampings 8 and the clamping block 9 are integrally installed. The clamping block 9 and the side plate 7 constitute a spring shock-absorbing structure through the shock dampings 8. The bulb is manually position-limited and fixed through the clamping block 9, eliminating the need for manual fixing by the staff and improving safety.

[0035] Refer to the accompanying drawings of the specification Figures 1-5, the clamping block 9 and the protective rubber 10 are integrally installed. The protective rubber 10 and the protective block 6 are made of the same material. The protective blocks 6 are semi-circularly distributed at the center of the fixed block 4. Through the cooperation of the protective rubber 10 and the protective block 6, the bulb is limited and protected to prevent accidental damage caused by knocking during fixation.

[0036] Refer to the attached drawings of the specification Figures 1-5 , the electric push rod 11 and the lifting block 12 have an integrated lifting structure. Protective blocks 15 are symmetrically distributed on both sides of the lifting block 12. The length of the protective block 15 is greater than the length of the filament. The center of the lifting block 12 coincides with the center of the socket 13. The lifting block 12 is protected by the protective block 15 to prevent it from descending too much and squeezing the bulb to cause damage.

[0037] Working principle: When in use, first, in the non-use state, place the filament of the bulb to be tested facing upward into the center of the fixed block 4 and press it, so that the bulb squeezes open the protective rubber 10 and enters the inside of the protective block 6. At the same time, the shock-absorbing damper 8 pushes the clamping block 9 to move towards the position of the bulb, that is, the fixation of the bulb is completed. Fill the fixed block 4 with bulbs in turn, and then place the linkage block 2 above the operating table 1 to prepare for the detection work;

[0038] Similarly, when the detection is about to be carried out, push the linkage block 2 to make it move. During the movement, the laser machine 14 emits laser downward all the time, that is, there is a laser point. When the laser point coincides with the marking block 5, stop moving. Then the electric push rod 11 pushes the lifting block 12 to descend, so that the socket 13 descends and contacts the filament for detection. When the lifting block 12 descends, the protective block 15 also descends. Then the protective block 15 abuts against the fixed block 4 to prevent the lifting block 12 from descending too much and causing damage to the bulb. Similarly, the sliding block 3 can be changed to a push rod or a screw rod for automatic drive according to the actual situation.

[0039] The above are all the preferred embodiments of the present invention, and the protection scope of the present invention is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
