Abstract
Description
Technical Field
[0001] This invention relates to the field of backlight module manufacturing technology, and in particular to an assembly equipment for backlight module manufacturing. Background Technology
[0002] The backlight module is one of the key components of an LCD panel. Its function is to provide sufficient brightness and a uniformly distributed light source. It uses the dot distribution of PC material light guide plate to break the interference phenomenon of light, and uniformly converts the line light source into a surface light source. It is mainly used to guide the direction of light scattering, so that the light distribution is more uniform and the brightness of the panel is uniform. When designing the back panel of the display, the light guide plate needs to be limited and supported to make the position of the light guide plate more stable and to ensure a good light guiding effect.
[0003] During the production of the backlight module, the light guide plate is fixedly mounted on the support platform. Then, a single guide plate slides the diffuser plate into the assembly equipment, placing the diffuser plate on top of the light guide plate. The precise alignment between the two components and the cleaning of the bonding area are manually ensured to facilitate stable welding and bonding. However, manual operation is affected by the operator's skills and attention. Prolonged manual operation leads to operator fatigue, which not only increases the probability of inaccurate component alignment and makes it difficult to guarantee the accuracy and consistency of the patch, but also causes quality problems such as incomplete cleaning leading to weak bonding, reducing the product qualification rate and increasing production costs.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.
[0033] Please see Figures 1 to 8 As shown, one embodiment of the present invention is provided:
[0034] An assembly equipment for producing backlight modules includes a support base 1. A symmetrical processing platform 2 and a feeding platform 3 are fixedly connected to both sides of the support base 1. The top of the feeding platform 3 is provided with a feeding component for automatic positioning and feeding and ensuring positioning accuracy. The inner side of the support base 1 is provided with a cleaning component for surface cleaning during the feeding process and ensuring cleaning effect. A motor 4 is fixedly connected to the outer side of the support base 1.
[0035] The feeding assembly includes a feeding seat 501. A fixing rod 505 is fixedly connected inside the support seat 1. The feeding seat 501 is rotatably connected to the outside of the fixing rod 505. A connecting seat 502 is fixedly connected to one end of the feeding seat 501 near the motor 4. A connecting shaft 507 is fixedly connected to the inside of the connecting seat 502. A transmission gear 508 is fixedly connected to one end of the connecting shaft 507 inside the support seat 1. An incomplete gear 509 is rotatably connected inside the support seat 1. The transmission gear 508 and the incomplete gear 509 mesh with each other. The incomplete gear 509 is fixedly connected to the output shaft of the motor 4.
[0036] The processing platform 2 enables the limited installation of the light guide plate, the loading platform 3 provides support for the bottom of the loading assembly, the motor 4 provides power for the rotation of the loading seat 501 and the movement and cleaning of the scraper 603, the clamping plate 503 clamps the diffuser plate so that the diffuser plate can be attached to the top of the light guide plate as the loading seat 501 rotates, the connecting seat 502 drives the loading seat 501 to rotate stably on the outside of the torsion spring 506, the connecting shaft 507 connects the transmission gear 508 and the connecting seat 502 so that the transmission gear 508 drives the connecting seat 502 to rotate, the transmission gear 508 and the incomplete gear 509 mesh with each other so that when they mesh, the output shaft of the motor 4 can drive the loading seat 501 to rotate to achieve precise loading of the diffuser plate, ensuring the fitting accuracy of each component, eliminating errors and mistakes in human operation, and ensuring the quality and consistency of the product.
[0037] Furthermore, the cleaning assembly includes a movable seat 601 fixedly connected to the feeding seat 501. A reciprocating screw 602 is slidably connected to the upper surface of the movable seat 601. The cleaning assembly also includes a mounting shaft 605 rotatably connected inside the movable seat 601. A slider 607 is slidably connected to the top of the movable seat 601. The reciprocating screw 602 is fixedly connected to the outer wall of the mounting shaft 605. The slider 607 is slidably connected between the movable seat 601 and the reciprocating screw 602. A worm gear 608 is fixedly connected to one end of the reciprocating screw 602 near the support seat 1. A worm 604 is fixedly connected to the outer wall of the fixed rod 505. The worm 604 meshes with the worm gear 608. A scraper 603 is detachably mounted on the upper surface of the slider 607.
[0038] The reciprocating screw 602 and worm gear 608 can be installed via the mounting shaft 605 to ensure synchronous rotation of the reciprocating screw 602 and worm gear 608. Through the meshing connection between the worm 604 and worm gear 608, the rotation of the reciprocating screw 602 outside the mounting shaft 605 can drive the worm gear 608 to rotate outside the worm 604. Under the action of the helical teeth on the outside of the worm 604, the worm gear 608 is pushed to rotate and drive the reciprocating screw 602. Since the protrusion in the slider 607 slides in the bidirectional helical groove on the outside of the reciprocating screw 602, the rotating reciprocating screw 602 pushes the protrusion to slide through the bidirectional helical groove. The sliding protrusion drives the slider 607 to slide within the movable seat 601, thereby driving the pusher scraper 603 to clean the surface of the diffuser plate through the slider 607.
[0039] Furthermore, the feeding assembly also includes a card plate 503 slidably connected to the top of the feeding seat 501, and a spring 510 is fixedly connected between the card plate 503 and the inner wall of the feeding seat 501.
[0040] The clamping plate 503, pushed by the spring 510, can clamp the diffuser plate placed in the loading seat 501, preventing them from moving or shifting during the bonding process, ensuring accurate positioning, avoiding them from falling or being damaged during cleaning or transportation, making the parts fit tightly with the substrate or other components, reducing gaps and errors, ensuring assembly accuracy, and improving bonding quality and optical performance.
[0041] Furthermore, a locking block 511 is fixedly connected to the top of the feeding platform 3, and the locking block 511 slides through the feeding seat 501 and is slidably connected to the inside of the card plate 503.
[0042] The locking block 511 enables the locking plate 503 inside the loading seat 501 to engage after the loading seat 501 is reset. Under the push of the inclined surface of the locking block 511, the locking plate 503 moves towards the inner wall of the loading seat 501 and compresses the spring 510. So that during the rotation of the loading seat 501, the locking plate 503 will engage with the diffuser plate under the stretching elastic force of the spring 510.
[0043] Furthermore, a torsion spring 506 is fixedly connected between the fixing rod 505 and the feeding seat 501, and the fixing rod 505 is rotatably connected to the connecting shaft 507.
[0044] The torsion spring 506 causes the feeding seat 501 to reset when the transmission gear 508 and the incomplete gear 509 disengage, so as to complete the reset after the feeding seat 501 rotates to feed material, so as to achieve cyclic and precise feeding and bonding of the diffuser plate, thereby improving the efficiency of the equipment.
[0045] Furthermore, a support plate 504 is fixedly connected to the upper surface of the processing platform 2, and the thickness of the support plate 504 is equal to the thickness of the push scraper 603.
[0046] With a support plate 504 of the same thickness as the scraper 603, when the diffuser plate is attached to the light guide plate by the loading seat 501, the lower surface of the scraper 603 is attached to the processing platform 2, and the upper surface of the support plate 504 is attached to the loading seat 501, so as to achieve stable support at both ends, so that the diffuser plate can be accurately attached to the light guide plate and the stability of the attached part is guaranteed.
[0047] Furthermore, a storage groove is provided on the side of the scraper 603 away from the support base 1, and the lower surface of the scraper 603 is in contact with the upper surface of the feed base 501.
[0048] The storage slot on the scraper 603 allows for the collection of impurities and dust during the cleaning process, preventing them from falling and affecting the bonding quality of the bonding surfaces.
[0049] Furthermore, a connecting block 606 is slidably connected inside the connecting seat 502, and the connecting block 606 is fixedly connected to the lower surface of the push scraper 603.
[0050] The connecting block 606 can support the end of the card plate 503 near the connecting seat 502, so as to ensure that the card plate 503 can slide stably across the surface of the diffuser plate, and can also act as a latch on the outside of the diffuser plate to prevent the diffuser plate from shifting and falling off during the cleaning process.
[0051] Based on the above preferred embodiments, the working principle of the present invention is as follows:
[0052] The initial state is as follows: the loading seat 501 is in contact with the upper surface of the loading platform 3; the toothed part of the incomplete gear 509 is in contact with the transmission gear 508; the worm 604 and the worm wheel 608 are in contact with each other; the slider 607 is located inside the movable seat 601 at the end closest to the fixed rod 505; the push scraper 603 is in contact with the upper surface of the loading seat 501; and the clamping block 511 achieves contact between the clamping plate 503 and the movable seat 601 and compresses the spring 510 through the inclined guide.
[0053] The assembly steps are as follows: First, the operator needs to place the light guide plate in the groove at the top of the processing platform 2, and then slide the diffuser plate into the loading seat 501 along the connecting seat 502. When the outer side of the diffuser plate is in contact with the movable seat 601, the operator starts the motor 4 so that its output shaft drives the incomplete gear 509 to rotate. The rotating incomplete gear 509 drives the transmission gear 508 that meshes with it to rotate. The rotating worm gear 608 drives the connecting shaft 507 that is fixedly connected to it to rotate. The rotating connecting shaft 507 drives the connecting seat 502 to rotate synchronously. The rotating connecting seat 502 drives the loading seat 501 to rotate under the support of the fixed rod 505. The rotating loading seat 501 drives the torsion spring 506 to tighten.
[0054] At the same time, the rotating loading seat 501 slides out from the clamping block 511. When the clamping plate 503 is completely removed from the top of the clamping block 511, the spring 510 elastically extends and resets, and drives the clamping plate 503 to clamp the diffuser plate in the loading seat 501. This prevents the diffuser plate from moving or shifting during the bonding process, ensures accurate positioning, and avoids them falling or being damaged during cleaning or transportation. It also ensures that the parts are tightly bonded to the substrate or other components, reduces gaps and errors, ensures assembly accuracy, and improves bonding quality and optical performance.
[0055] Since the worm 604 is fixedly installed on the inner side of the support base 1 by the fixing rod 505, and the worm wheel 608 is meshed with the worm 604, when the loading base 501 drives the movable base 601 to rotate, the movable base 601 can rotate by driving the worm wheel 608 to slide on the outside of the worm 604 through the mounting shaft 605. The rotating worm wheel 608 drives the mounting shaft 605 to rotate synchronously. The rotating mounting shaft 605 drives the reciprocating screw 602 to rotate. Under the sliding connection between the outer bidirectional helical groove and the inner protrusion of the slider 607, the rotating reciprocating screw 602 drives the slider 607 to slide between the movable base 601 and the reciprocating screw 602. The sliding slider 607 drives the pusher scraper 603 to move towards... Moving away from the support base 1, the moving scraper 603 can ensure sliding stability under the support of the connecting block 606. Through the storage groove opened on the scraper 603, the impurities and dust cleaned during the movement of the scraper 603 are collected, preventing dust and impurities from falling and affecting the bonding quality of the bonding surface. This allows the scraper 603 to more stably clean the surface of the diffuser plate, remove dust, dirt and impurities, ensure a tighter bonding between the patch module and other components, reduce the generation of air bubbles and voids, prevent contaminants from entering the module, reduce the risk of defects and failures, improve the reliability and stability of the product, and reduce additional cleaning steps and time.
[0056] When the pusher 603 moves to the top furthest point away from the support base 1, the loading base 501 drives the diffuser plate to adhere to the light guide plate on the processing platform 2. Under the support of the pusher 603 and the support plate 504, the stability of the adhered part is ensured, so that the diffuser plate can be evenly and accurately adhered to the surface of the light guide plate, eliminating errors and mistakes in human operation, realizing fast and accurate component mounting, ensuring product quality and consistency, reducing the time and effort of manual operation, reducing the defect rate, improving the qualification rate of finished products, realizing the lean production concept, reducing waste and improving process efficiency.
[0057] At the same time, the incomplete gear 509 disengages from the transmission gear 508, and the torsion spring 506 drives the loading seat 501 to rotate under the relaxed elastic force. The rotating loading seat 501 moves to the top of the loading platform 3 and fits against it. During the rotation, the locking block 511 on the loading platform 3 will pass through the loading seat 501 and push the locking plate 503 to compress the spring 510 under the guidance of the inclined surface, so as to realize the locking and fixing of the next set of modules and improve the process efficiency.
