Description

Technical Field

[0001] The invention relates to the technical field of electronic product detection, in particular to a laser detection device for an electronic product housing. Background Art

[0002] Electronic products are products that use electricity as the basis of their work, mainly including watches, smart phones, telephones, televisions and mobile communication products. In the process of electronic product production, laser detection equipment is needed to scan the outer shell of the electronic product to detect whether there are any defects in the product shell.

[0003] For example, the patent with publication number CN218041477U discloses a dual-station laser inspection device for mobile phone cases. This patent places the mobile phone case into the first inspection station and the second inspection station, so that the clamping plate clamps it. Under the action of the telescopic rod and the spring, mobile phone cases of different sizes can be clamped. The setting of the first inspection station and the second inspection station makes the inspection device form a dual-station. When one inspection station is inspecting, the other inspection station can be used for material collection and loading. The two stations are carried out alternately, which effectively avoids the shutdown phenomenon caused by material collection and loading, and enables the inspection equipment to run continuously without stopping during the inspection process, effectively improving the equipment inspection efficiency. However, in the actual use of such devices, dust and impurities may adhere to the surface of the shell of some electronic products, which will interfere with the laser scanning results during the inspection, resulting in problems affecting the equipment detection accuracy.

[0016] The present invention provides a laser detection device for electronic product housing, which has the following beneficial effects:

[0017] 1. In the present invention, after the conveyor belt conveys the electronic product shell to the bottom of the fixed box, the electronic product shell will contact the sponge on the outside of the cleaning roller, thereby wiping and cleaning the electronic product shell. During this process, the rack will also contact the driving gear, thereby driving the cleaning roller to roll through the first double gear, the second double gear, and the driven gear, and under the acceleration structure of the first double gear and the second double gear, the rotation speed of the cleaning roller can be increased, thereby improving the effect of wiping and cleaning the shell, and the cleaning roller can rotate clockwise to block impurities on the left side of the cleaning roller. At this time, the motor will also drive the fan shaft to rotate, thereby forming a negative pressure inside the fixed box, which can suck dust impurities into the upper part of the fixed box and be blocked by the filter plate, thereby automatically cleaning the top of the electronic product shell during transportation to avoid affecting the accuracy of subsequent detection.

[0018] 2. The return spring of the present invention will push the pulley seat under the limit of the loading platform, so that the slide bar pulls the positioning plate, and a larger placement space can be formed on the top of the loading platform to place the electronic product housing therein. After placement, when the conveyor belt drives the loading platform to move to the middle of the conveyor belt, the limit plate will contact the pulley seat, thereby pushing the pulley seat, so that the slide bar drives the positioning plate to move toward the electronic product housing, automatically centering the electronic product housing, and increasing the friction force during positioning through the rubber pad to avoid the housing being offset when the cleaning roller cleans the electronic product housing, and also improving the stability of the electronic product housing during transportation. After detection, the pulley seat will be separated from the cleaning roller, and at this time, the positioning plate can automatically release the electronic product housing under the action of the return spring, making unloading very convenient.

[0019] The cam is driven to rotate by the bevel gear set and the reducer during operation. At this time, when the convex portion of the cam is located at the bottom, the movable box moves downward under the action of gravity, and the stability during movement is improved by the guide rod, so that the pressure roller can press the stained tape tightly on the top of the cleaning roller, and the stickiness of the stained tape is relatively general, and the sponge on the outside of the cleaning roller will not be damaged. At the same time, when the cleaning roller rotates, the stained tape will be pulled, thereby pulling the stained tape on the unwinding roller out, and the excessive dust and impurities on the cleaning roller can be automatically adhered and removed, avoiding excessive dust and impurities adhering to the cleaning roller and affecting the effect of subsequent cleaning, and when the convex portion of the cam moves to the top, it will drive the movable box to move upward through the driving roller, so that the stained tape is separated from the cleaning roller, and the cleaning roller can be intermittently adhered and cleaned, avoiding continuous adhesion and wasting of excessive stained tape. The cleaning roller will be automatically cleaned only after a period of use, so that the stained tape is fully utilized, saving maintenance costs.

[0020] The invention also drives the pinion to rotate through the large gear when the stained adhesive tape on the take-up roller is pulled, thereby driving the take-up roller to rotate simultaneously through the driving shaft, the sliding sleeve, the first end gear plate and the second end gear plate, so that the taken-up roller can be automatically reeled up. At the same time, the acceleration structure formed by the large gear and the small gear can increase the rotation speed of the take-up roller, so that when there is a tape roll with a large radius on the unwinding roller, by increasing the rotation speed of the take-up roller, it can be avoided that when one circle is rotated, the length of the tape when pulling out and winding is inconsistent due to the different radius of the stained adhesive tape outside the unwinding roller and the take-up roller, and the loosening condition can be avoided. When the speed of the take-up roller is too fast and the stained adhesive tape is too tight, the first end gear plate will squeeze the compression spring under the guidance of the inclined surface of the tooth portion on the second end gear plate, so that the first end gear plate and the second end gear plate slide, and the take-up roller will not be driven to rotate, thereby avoiding the jamming condition caused by the too fast rotation of the take-up roller when too much stained adhesive tape is wound on the take-up roller.

[0030] The specific operation is as follows: the return spring 306 will push the pulley seat 305 under the limit of the loading platform 301, so that the slide bar 302 pulls the positioning plate 303, which can form a larger placement space on the top of the loading platform 301, so that the electronic housing can be placed on the loading platform 301, and when the conveyor belt 2 drives the loading platform 301 to move to the bottom of the fixed box 401, the limiting plate 307 will contact the pulley seat 305, thereby pushing the pulley seat 305, so that the slide bar 302 drives the positioning plate 303 to move toward the electronic product housing, automatically centering the electronic product housing, and increasing the friction during positioning through the rubber pad 304, avoiding the housing from being offset when the cleaning roller 410 cleans the electronic product housing, and also improving the stability of the electronic product housing during transportation, and when the rack 405 on the loading platform 301 contacts the driving gear 406, it can be moved through the first double gear 407, the second double gear 408, The driven gear 409 drives the cleaning roller 410 to roll, and under the acceleration structure of the first double gear 407 and the second double gear 408, the rotation speed of the cleaning roller 410 is increased, thereby improving the effect of wiping and cleaning the outer shell, and the cleaning roller 410 rotates clockwise, which can block impurities at the left part of the cleaning roller 410.

The dirt sticking assembly 5 also includes a driving roller 504, a movable box 505, a guide rod 506 and a baffle 507. A driving roller 504 is arranged on the top of the cam 503, and the movable box 505 is arranged at one end of the driving roller 504. The two ends of the movable box 505 are slidably connected with guide rods 506, and the guide rods 506 are fixedly connected to the fixed box 401. A baffle 507 is slidably connected to one side of the interior of the movable box 505, and the baffle 507 is fixedly connected to the movable box 505. The sticky component 5 also includes a reeling roller 508, a pressure roller 509, a reeling roller 510 and a stained adhesive tape 511. The upper end of the interior of the movable box 505 is provided with a reeling roller 508, and the lower part of one end of the movable box 505 is rotatably connected to the pressure roller 509, and the center of the interior of the movable box 505 is rotatably connected to the reeling roller 510, and A contaminated tape 511 is arranged on the outside of the winding roller 510, a tensioning assembly 6 is arranged on one side of the movable box 505, a bracket 7 is arranged above the middle of the frame 1, and a laser detection head 8 is arranged in the middle of the bracket 7, the tensioning assembly 6 includes a large gear 601, a small gear 602 and a drive shaft 603, a large gear 601 is fixed to one end of the unwinding roller 508, and a small gear 602 is meshed at the lower part of the large gear 601, and a drive shaft 603 is fixed to the middle of the small gear 602, and the tensioning assembly 6 also includes a limit frame 604, a sliding sleeve 605 and a first end gear The outer middle part of the driving shaft 603 is rotatably connected to the limit frame 604, and the limit frame 604 is fixedly connected to the movable box 505. One end of the driving shaft 603 is slidably connected to the sliding sleeve 605, and one end of the sliding sleeve 605 is fixed with the first end toothed disc 606. The tensioning assembly 6 also includes a compression spring 607 and a second end toothed disc 608. A compression spring 607 is provided on one side of the first end toothed disc 606, and the other side of the first end toothed disc 606 is slidably connected to the second end toothed disc 608, and the second end toothed disc 608 is fixedly connected to the winding roller 510.

[0032] The specific operation is as follows: the fan shaft 403 drives the cam 503 to rotate through the bevel gear set 501 and the reducer 502. At this time, when the convex part of the cam 503 is located at the bottom, the movable box 505 will move downward under the action of gravity, and the stability during movement is improved through the guide rod 506. The pressure roller 509 can press the stained tape 511 on the top of the cleaning roller 410, and the stained tape 511 has a relatively general viscosity and will not damage the sponge on the outside of the cleaning roller 410. At the same time, when the cleaning roller 410 rotates, the stained tape 511 will be pulled, thereby pulling out the stained tape 511 on the unwinding roller 508, and the excessive powder on the cleaning roller 410 can be automatically removed. Dust and impurities are adhered and removed. During this process, when the stained tape 511 on the take-up roller 510 is pulled, the small gear 602 is driven to rotate through the large gear 601. At this time, the compression spring 607 pushes the first end toothed disc 606 under the limit of the limit frame 604 to make it close to the second end toothed disc 608. Therefore, the take-up roller 510 can be driven to rotate simultaneously through the drive shaft 603, the sliding sleeve 605, the first end toothed disc 606 and the second end toothed disc 608 to automatically reel up the pulled stained tape 511. At the same time, the acceleration structure formed by the large gear 601 and the small gear 602 can increase the rotation speed of the take-up roller 510, so that when the unwinding roller 50 When there is a tape roll with a large radius on 8, by increasing the rotation speed of the take-up roller 510, it is possible to avoid the situation where the length of the contaminated tape 511 on the outside of the unwinding roller 508 and the take-up roller 510 is inconsistent when it rotates one circle, and when the take-up roller 510 rotates too fast and causes the contaminated tape 511 to be too tight, the first end toothed disc 606 will squeeze the compression spring 607 under the guidance of the inclined surface of the tooth portion on the second end toothed disc 608, so that the first end toothed disc 606 and the second end toothed disc 608 slip, and the take-up roller 510 will not be driven to rotate, thereby avoiding the situation when too much contaminated tape 511 is wound on the take-up roller 510. At 11, the winding roller 510 may get stuck due to rotating too fast, and when the convex part of the cam 503 moves upward, it will drive the movable box 505 upward through the driving roller 504, so that the stained tape 511 is separated from the cleaning roller 410, and the cleaning roller 410 can be intermittently adhered and cleaned to avoid continuous adhesion and waste of excessive stained tape 511. The cleaning roller 410 will be automatically cleaned only after a period of use, and the stained tape 511 can be fully utilized. After that, when the stage 301 drives the electronic product housing to move to the bottom of the bracket 7, the laser detection head 8 can be used to perform laser scanning on the electronic product housing.

[0033] In summary, when the electronic product housing laser detection device is used, first, the reset spring 306 will push the pulley seat 305 under the limit of the stage 301, so that the slide bar 302 pulls the positioning plate 303, so that a larger placement space can be formed on the top of the stage 301, and then the electronic housing is placed on the stage 301. Secondly, when the conveyor belt 2 drives the stage 301 to move to the bottom of the fixed box 401, the limit plate 307 will contact the pulley seat 305, thereby pushing the pulley seat 305, so that the slide bar 302 drives the positioning plate 303 to move toward the electronic product housing, automatically positioning the electronic product housing in the center, and increasing the friction during positioning through the rubber pad 304. Then, the rack 405 on the stage 301 will contact the driving gear 406. The cleaning roller 410 is driven to roll through the first double gear 407, the second double gear 408 and the driven gear 409, and the outer shell is automatically wiped and cleaned. The cleaning roller 410 rotates clockwise, which can block the impurities at the left part of the cleaning roller 410. At this time, the motor 402 also drives the fan shaft 403 to rotate, so that a negative pressure is formed inside the fixed box 401, and the dust impurities can be sucked into the upper part of the fixed box 401 and blocked by the filter plate 404. Then, the fan shaft 403 also drives the cam 503 to rotate through the bevel gear set 501 and the reducer 502. At this time, when the convex part of the cam 503 is located at the bottom, the movable box 505 will move downward under the action of gravity, and the stability during movement is improved through the guide rod 506. 09 can press the stained adhesive tape 511 onto the top of the cleaning roller 410, so when the cleaning roller 410 rotates, it will pull the stained adhesive tape 511, thereby pulling out the stained adhesive tape 511 on the unwinding roller 508, and automatically remove the excessive dust and impurities on the cleaning roller 410, so as to avoid excessive dust and impurities adhering to the cleaning roller 410 and affecting the subsequent cleaning effect. In this process, when the stained adhesive tape 511 on the winding roller 510 is pulled, the small gear 602 is also driven to rotate through the large gear 601. At this time, the compression spring 607 will push the first end toothed disc 606 under the limit of the limit frame 604, so that it is tightly attached to the second end toothed disc 608, so that it can be driven through the drive shaft 603, the sliding sleeve 605, the first end toothed disc 606 and the second end toothed disc 608. The toothed discs 608 at both ends drive the winding roller 510 to rotate simultaneously to automatically wind up the pulled out stained tape 511, and at the same time, the large gear 601 and the small gear 602 are used to increase the rotation speed of the winding roller 510 to avoid slackness. When the rotation speed of the winding roller 510 is too fast and the stained tape 511 is too tight, the first end toothed disc 606 will squeeze the compression spring 607 under the guidance of the inclined surface of the tooth portion on the second end toothed disc 608, so that the first end toothed disc 606 and the second end toothed disc 608 slip, so as to avoid the situation of jamming caused by the winding roller 510 rotating too fast. Afterwards, when the convex part of the cam 503 moves to the upper part, it will drive the movable box 505 to move upward through the driving roller 504, so that the stained tape 511 is separated from the cleaning roller 410.The cleaning roller 410 can be intermittently adhered and cleaned to avoid continuous adhesion and waste of excessive contaminated tape 511. Finally, when the stage 301 drives the electronic product shell to move to the bottom of the bracket 7, the laser detection head 8 can be used to perform laser scanning on the electronic product shell. After the detection, when the stage 301 drives the electronic product to move to the right end of the rack 1, the pulley seat 305 will separate from the cleaning roller 410. At this time, under the action of the reset spring 306, the positioning plate 303 can automatically release the electronic product shell, which is convenient for unloading.
