Description

A detection device for decabromodiphenyl ether in electronic and electrical products Technical Field

[0001] This utility model relates to the field of electronic and electrical product testing technology, specifically to a device for detecting decabromodiphenyl ether in electronic and electrical products. Background Technology

[0002] Decabromodiphenyl ether (DBD) is a common flame retardant widely used in electrical products. To ensure the safety and sustainability of electronic and electrical products, it is necessary to detect DBD in these products. Raman spectroscopy is based on the inelastic scattering effect of molecules on laser photons. DBD molecules produce specific Raman scattering spectra under laser irradiation. By analyzing these spectral characteristics, the presence of DBD in electronic and electrical product samples can be identified.

[0003] However, the overall functionality of the testing device is low. When testing electronic and electrical products, the product position cannot be stably aligned with the testing head, which can lead to inaccurate test results and affect the overall testing effect of the device and the stability of subsequent testing work. Summary of the Invention

[0004] The purpose of this invention is to provide a detection device for decabromodiphenyl ether in electronic and electrical products, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a detection device for decabromodiphenyl ether in electronic and electrical products, comprising a detection chamber, drive rollers evenly and at equal intervals installed at the bottom of the detection chamber, hydraulic rods installed on both sides of the top of the detection chamber, a detection platform installed at the bottom of the two sets of hydraulic rods, a Raman spectrometer installed at the middle position of the top of the detection platform, a detection head installed at the bottom of the Raman spectrometer, limiting mechanisms provided on both sides of the detection chamber, a push plate provided on one side of the limiting mechanism, an air inlet chamber provided at the top of one side of the detection chamber, filter plates fixedly connected to both sides of the air inlet chamber, and a rotating mechanism provided on one side of the detection chamber.

[0006] Preferably, a door is installed on one side of the outside of the testing chamber, dust curtains are installed inside the two sides of the testing chamber, and vacuum cleaners are installed on the two sides inside the testing chamber.

[0007] Preferably, the limiting mechanism includes limiting plates fixedly connected to both sides of the bottom end of the detection platform, connecting rods fixedly connected to both sides of the detection platform, and a limiting block that slides inside the detection chamber fixedly connected to one side of the connecting rod.

[0008] Preferably, the two sides inside the detection chamber are rotatably connected to a rotating shaft, and the bottom of the two sides inside the detection chamber are slidably connected to a slide rod with one side fixedly connected to a push plate. A movable block is fixedly connected to one side of the slide rod, a spring is fixedly connected to one side of the movable block, and a second pull rope with its top end fixedly connected to a limit block is fixedly connected to one side of the movable block.

[0009] Preferably, the rotating mechanism includes a first pull rope fixedly connected to the middle position of one side of the testing platform, a rotating mechanism fixedly connected to one side of the inside of the testing chamber and the first pull rope, torsion springs fixedly connected to both sides of the rotating mechanism and the testing chamber, and first gears fixedly connected to both sides of the outside of the first rotating rod.

[0010] Preferably, a second gear is meshed with one side of each of the two sets of first gears, a second rotating rod that rotates inside the filter plate is fixedly connected to one side of the second gear, and a fan is fixedly connected to one side of the second rotating rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This detection device for decabromodiphenyl ether in electronic and electrical products has limit plates on both sides of the bottom of the detection platform. When the hydraulic rod drives the detection platform to move downward, the limit plates can complete the limiting work at the front and rear ends of the electronic product. At the same time, the downward movement of the detection platform can cause the connecting rods on both sides to drive the limit blocks downward. At this time, the second pull rope at the bottom of the limit block cancels the pull on the movable block. Due to the reaction force of the spring being squeezed, the push plate on one side of the slide rod can be pushed by the movable block to complete the limiting work at the front and rear ends of the electronic product, thereby stably carrying out the detection of decabromodiphenyl ether in electronic products and improving the overall use effect of the detection device.

[0013] 2. This detection device for decabromodiphenyl ether in electronic and electrical products comprises a first rotating rod with multiple sets of first pull ropes wound around it on one side of the detection platform. When the detection platform moves downward, the first pull ropes pull the first rotating rod to rotate. At this time, the first rotating rod twists the torsion springs on both sides. Simultaneously, the first gear on the first rotating rod can drive the second rotating rod to rotate through the second gear. At this time, the fan on one side of the second rotating rod rotates, which can accelerate the input of external air into the detection chamber. When the detection platform moves upward, the reaction force of the torsion springs can drive the fan to reverse, thereby achieving rapid exhaust of the detection chamber. By rapidly exchanging the air inside the detection chamber, the stability of the detection environment inside the detection chamber can be ensured, and the stable operation of the monitoring device can be guaranteed, thus improving the overall functionality of the detection device.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please refer to Figures 1-5. This utility model provides two technical solutions:

[0022] Example 1: A detection device for decabromodiphenyl ether in electronic and electrical products includes a detection chamber 1. Drive rollers 103 are evenly and equidistantly installed at the bottom of the detection chamber 1. Hydraulic rods 105 are installed on both sides of the top of the detection chamber 1. A detection platform 2 is installed at the bottom of the two sets of hydraulic rods 105. A Raman spectrometer 3 is installed at the center of the top of the detection platform 2. A detection head 301 is installed at the bottom of the Raman spectrometer 3. Limiting mechanisms 4 are provided on both sides of the inside of the detection chamber 1. A push plate 5 is provided on one side of each limiting mechanism 4. An air inlet chamber 6 is provided at the top of one side of the chamber 1. Filter plates 601 are fixedly connected to both sides inside the air inlet chamber 6. A rotating mechanism 7 is provided on one side of the chamber 1. A drive motor is installed on one side of the drive roller 103. The drive roller 103 can be rotated by starting the motor, and the electronic and electrical products at the top can be moved and transported. The sample surface is irradiated with a laser beam by the detection head 301 at the bottom of the Raman spectrometer 3. The Raman spectrum of the scattered light is collected and analyzed, which can realize non-contact detection of electronic and electrical product samples.

[0023] A door 101 is installed on one side of the outside of the testing chamber 1. Dust curtains 102 are installed inside both sides of the testing chamber 1. Vacuum cleaners 104 are installed on both sides inside the testing chamber 1. The vacuum cleaners 104 can assist in removing dust from electronic and electrical products entering the testing chamber 1. At the same time, the door 101 can be opened to carry out inspection and maintenance work inside the testing chamber 1, and the dust curtains 102 can reduce the entry of external dust into the testing chamber 1.

[0024] The limiting mechanism 4 includes limiting plates 201 fixedly connected to both sides of the bottom end of the detection platform 2. Connecting rods 202 are fixedly connected to both sides of the detection platform 2. A limiting block 203 that slides in the detection chamber 1 is fixedly connected to one side of the connecting rods 202. When the detection platform 2 moves up and down, the limiting block 203 can be driven to move up and down in the detection chamber 1 by the connecting rods 202. At the same time, the position of the limiting plate 201 is in the middle of the gap between the two sets of drive rollers 103, so as not to affect the normal operation of the drive rollers 103.

[0025] Rotating shafts 106 are rotatably connected to both sides inside the testing chamber 1. Sliding rods 401, fixedly connected to push plate 5 on one side, are slidably connected to the bottom of both sides inside the testing chamber 1. Movable block 402 is fixedly connected to one side of sliding rod 401. Spring 403 is fixedly connected to one side of movable block 402. Second pull rope 404, fixedly connected to limit block 203 at its top, is fixedly connected to one side of movable block 402. The pulling direction of second pull rope 404 can be changed by rotating shafts 106. When the testing platform 2 is raised, the second pull rope 404 can be pulled by limit block 203. At this time, the second pull rope 404 pulls movable block 402 to move, which can cause movable block 402 to squeeze spring 403 on one side. When the testing platform 2 drives limit block 203 to move downward, limit block 203 drives second pull rope 404 to release the wire. Due to the reaction force of spring 403 being squeezed, push plate 5 can be pushed by movable block 402 and sliding rod 401 to complete the clamping and limiting work on both sides of electronic and electrical products.

[0026] Example 2 differs from Example 1 mainly in that:

[0027] A detection device for decabromodiphenyl ether in electronic and electrical products includes a rotating mechanism 7 comprising a first pull rope 204 fixedly connected to the middle of one side of a detection platform 2, a rotating mechanism 7 fixedly connected to one side of the detection chamber 1 and one side of which is fixedly connected to the first pull rope 204, torsion springs 702 fixedly connected to both sides of the rotating mechanism 7 and one side of which is connected to the detection chamber 1, first gears 703 fixedly connected to both sides of the exterior of a first rotating rod 701, a second gear 8 meshing with one side of two sets of first gears 703, a second rotating rod 801 rotating inside a filter plate 601 fixedly connected to one side of the second gear 8, a fan 802 fixedly connected to one side of the second rotating rod 801, and the first pull rope 204 being fixedly connected to the first rotating rod. Multiple strands are wound on 701. When the testing platform 2 moves downward, the first pull rope 204 can pull the first rotating rod 701 to rotate. At this time, the first rotating rod 701 twists the torsion springs 702 on both sides. At the same time, the first gear 703 on the first rotating rod 701 can drive the fan 802 to rotate through the second gear 8 and the second rotating rod 801. When the testing platform 2 is raised, due to the reaction force of the torsion springs 702 being twisted, the first rotating rod 701 can drive the first pull rope 204 to wind up. At this time, the first rotating rod 701 can drive the second gear 8 and the second rotating rod 801 to reverse in the opposite direction through the first gear 703. At the same time, the contents not described in detail in this specification are all prior art known to those skilled in the art.

[0028] In this embodiment, the electronic and electrical product to be tested is placed at the top of the drive roller 103 inside the testing chamber 1. The drive roller 103 is activated to move the electronic and electrical product. When the electronic and electrical product moves to the bottom of the testing platform 2, the hydraulic rod 105 is activated to push the testing platform 2 downward. At this time, the bottom limiting plate 201 of the testing platform 2 can limit the left and right ends of the electronic and electrical product. At the same time, the downward movement of the testing platform 2 can release the limiting blocks 203 on both sides of the testing platform 2 from pulling the second pull rope 404. At this time, the movable block 402 on one side of the second pull rope 404 can push the push plate 5 through the slide rod 401 to complete the clamping work of the front and rear ends of the electronic and electrical product. The sample surface is irradiated with a laser beam by the detection head 301 at the bottom of the Raman spectrometer 3, and the Raman spectrum of the scattered light is collected and analyzed, so as to realize the detection of decabromodiphenyl ether of the electronic and electrical product sample.
