Description

Technical Field

[0001] This invention relates to the field of backlight module assembly technology, specifically a backlight module assembly equipment and its application in display panel production. Background Technology

[0002] The backlight module in an LCD monitor is a key component that ensures the brightness of the screen display. Since liquid crystals themselves do not emit light, the backlight module's role is to provide a uniform, high-brightness light source for the liquid crystal layer, making the image clearly visible.

[0003] Backlight modules can be classified into two types: edge-lit and direct-lit. Edge-lit backlights typically have light sources distributed on one or both sides, while direct-lit backlights have multiple point light sources distributed on the upper surface.

[0004] Regardless of the type of backlight module, in order to ensure the safe use of the backlight module, a protective frame needs to be installed on the side connected to the PCB board. However, since the backlight module has a light source on its surface, it cannot be fixed by clamping the workpiece. Usually, the protective frame can only be assembled to the side of the backlight module manually, which leads to low assembly efficiency.

[0005] To address this, the backlight module can be supported using negative pressure adsorption and edge limiting. Before inserting the protective frame, the edge limiting is controlled to allow the backlight module to form a free-floating end on its side, thus avoiding interference with the protective frame during insertion. However, since the backlight module itself has a certain degree of flexibility, when the support force is removed, the free-floating end of the backlight module will inevitably deform, leading to misalignment with the protective frame. Summary of the Invention

[0006] The purpose of this invention is to provide a backlight module assembly equipment and its application in display panel production, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A backlight module assembly device, comprising:

[0009] The machine base, and the feeding plate that is slidably set in the machine base. The feeding plate is fixed with symmetrically arranged support plates and fixing plates. The feeding plate is equipped with a support component for carrying the backlight module.

[0010] Also includes:

[0011] A double-sided support mechanism is provided on the support plate, and the double-sided support mechanism is connected to a first support roller and a second support roller for performing support actions on the upper and lower sides of the free end of the backlight module.

[0012] A bidirectional pressure mechanism is mounted on the fixed plate and connected to the bidirectional support mechanism.

[0013] A push component is disposed on the machine base, and a protective frame is connected to the push component. A plug-in slot is formed on the side of the protective frame.

[0014] When the protective frame moves toward the free end of the backlight module, the bidirectional pressure mechanism can control the first support roller and the second support roller to perform the yielding and squeezing actions in sequence and synchronously.

[0015] As a further aspect of the present invention: the double-sided support mechanism includes two guide columns fixed on the support plate and arranged symmetrically, a guide slider is slidably mounted on the guide column, and a first spring is sleeved on the guide column, with the two ends of the first spring abutting against the guide slider and the support plate respectively.

[0016] As a further embodiment of the present invention: the double-sided support mechanism further includes a connecting plate fixed to the side end of the guide slider, a groove is formed on the connecting plate, a sliding block is slidably installed in the groove, and a receiving plate that is rotatably connected to the first support roller and the second support roller is fixed on the sliding block.

[0017] As a further embodiment of the present invention: the bidirectional pressure mechanism includes an upper support and a lower support respectively mounted on the two connecting plates.

[0018] As a further embodiment of the present invention: the upper support member includes a second support column fixed to one of the connecting plates, the second support column has a third sliding plate slidably connected to the sliding block, the third sliding plate has a third limiting post fixedly fixed, and the fixed plate has a guide groove that slidably engages with the third limiting post;

[0019] It also includes a fourth spring that is sleeved on the second support column and abuts against the third sliding plate.

[0020] As a further embodiment of the present invention: the lower support member includes a first support column fixed to another connecting plate, the first support column has a first sliding plate slidably connected to the sliding block, a first limiting post is fixed on the first sliding plate, and a U-shaped groove is formed on the fixed plate to slide and fit with the first limiting post.

[0021] It also includes a guide component and an elastic component disposed on the first support column for controlling the movement of the first sliding plate.

[0022] As a further embodiment of the present invention: the guiding component includes a guiding groove formed on the fixed plate, a second sliding plate is axially slidably attached to the first support column, and a second limiting post is fixed on the second sliding plate and slidably engaged with the guiding groove.

[0023] As a further embodiment of the present invention: the elastic component includes a second spring and a third spring sleeved on the first support column, the two ends of the second spring abutting against the connecting plate and the first sliding plate respectively, and the two ends of the third spring abutting against the first sliding plate and the second sliding plate respectively.

[0024] As a further embodiment of the present invention: the pushing component includes a cylinder fixed on the machine base, a push plate fixed to the telescopic end of the cylinder, and a suction cup fixed on the push plate for adsorption connection with the protective frame.

[0025] The application of a backlight module assembly equipment in display panel production includes the aforementioned backlight module assembly equipment.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows: When the protective frame is connected to the side of the backlight module, the present invention can gradually release the free end of the backlight module through the first support roller and the second support roller to prevent the free end of the backlight module from being suspended too long, which would cause the backlight module to deform itself and thus cause misalignment of the insertion position with the protective frame. Specifically, when the protective frame abuts against the first support roller and the second support roller, the first support roller and the second support roller will make a yielding action, so that the release amount of the free end of the backlight module gradually increases, so that the free end of the backlight module can smoothly complete the insertion action with the insertion slot. After the free end of the backlight module is inserted into the insertion slot, under the action of the bidirectional pressure mechanism, the first support roller is controlled to perform a limiting support action on the upper side of the protective frame, and at the same time, the second support roller is controlled to perform a squeezing action on the lower side of the protective frame, so that the adhesive applied on the inner side of the protective frame can smoothly adhere to the lower side of the free end of the backlight module, ensuring smooth assembly of the protective frame and the backlight module.

[0027] Since the free end of the backlight module is immediately inserted into the insertion slot after being released, the free end of the backlight module will not deform, ensuring that the free end of the backlight module and the insertion slot are always in a mutually mating position.

[0028] After the protective frame is inserted into place, the second support roller can automatically separate from the side of the protective frame and move to the lower side of the protective frame to automatically provide thrust to the lower side of the protective frame. Under the action of heating, it ensures that the adhesive is completely bonded to the backlight module, so as to ensure that the protective frame will not loosen after insertion. In this way, through the automatic adjustment of the positions of the first and second support rollers, the slow release of the free end of the backlight module and the limiting support of the protective frame can be adaptively completed to ensure smooth assembly.

[0043] 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 scope of protection of the present invention.

[0044] Furthermore, elements in this invention are referred to as being "fixed to" or "set on" another element, which may be directly on the other element or may also include an intervening element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or may also include an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0045] Please see Figures 1-13 In this embodiment of the invention, a backlight module assembly device includes:

[0046] The machine base 1 and the feeding plate 3 slidably disposed in the machine base 1 are provided. The feeding plate 3 is fixed with a support plate 301 and a fixing plate 6 arranged symmetrically. The feeding plate 3 is provided with a support component for carrying the backlight module. The support component includes an air chamber 4 fixed on the feeding plate 3. The air chamber 4 is fixed with a fixture 5 fixedly connected to the support plate 301. The fixture 5 has a plurality of negative pressure holes communicating with the air chamber 4. The fixture 5 is fixed with a plurality of limiting blocks for restricting the movement of the backlight module.

[0047] Also includes:

[0048] A double-sided support mechanism is provided on the support plate 301. The double-sided support mechanism is connected to a first support roller 17 and a second support roller 18 for performing support actions on the upper and lower sides of the free end of the backlight module.

[0049] A bidirectional pressure mechanism is mounted on the fixed plate 6 and connected to the bidirectional support mechanism.

[0050] A push component is provided on the machine base 1, and a protective frame 10 is connected to the push component. A plug-in slot 1001 is formed on the side of the protective frame 10.

[0051] When the protective frame 10 moves toward the free end of the backlight module, the bidirectional pressure mechanism can control the first support roller 17 and the second support roller 18 to perform the yielding and squeezing actions in sequence.

[0052] The machine base 1 has a fixed workbench 2, and the workbench 2 has a fixed guide rail 201 that is slidably connected to the feeding plate 3. The feeding plate 3 can slide radially along the guide rail 201 under the drive of the drive source. The drive source can be a hydraulic cylinder or a belt conveyor, and this application does not limit it.

[0053] Specifically, to protect the PCB board and one edge of the backlight module, the protective frame 10 needs to be inserted into the side of the backlight module. When the backlight module is placed on the supporting assembly, under the action of the double-sided support mechanism, the first support roller 17 and the second support roller 18 support the free end of the backlight module to ensure that the backlight module does not deform and that the orientation of the free end does not change. At this time, under the action of the pushing assembly, the protective frame 10 moves towards the free end of the backlight module. When the protective frame 10 abuts against the first support roller 17 and the second support roller 18, the first... The support rollers 17 and 18 will make a yielding action, so that the release amount of the free end of the backlight module gradually increases, so that the free end of the backlight module can smoothly complete the insertion action with the insertion slot 1001. After the free end of the backlight module is inserted into the insertion slot 1001, under the action of the bidirectional pressure mechanism, the first support roller 17 is controlled to perform a limiting support action on the upper side of the protective frame 10, and at the same time, the second support roller 18 is controlled to perform a squeezing action on the lower side of the protective frame 10, so that the glue applied on the inner side of the protective frame 10 can smoothly adhere to the lower side of the free end of the backlight module, ensuring that the protective frame 10 and the backlight module are assembled smoothly.

[0054] Please see Figures 1-4 , Figures 8-11 The double-sided support mechanism includes two guide columns 11 fixed on the support plate 301 and arranged symmetrically. A guide slider 12 slides axially on the guide column 11. A first spring 13 is sleeved on the guide column 11. The two ends of the first spring 13 abut against the guide slider 12 and the support plate 301, respectively. The double-sided support mechanism also includes a connecting plate 14 fixed to the side end of the guide slider 12. A groove 1401 is formed on the connecting plate 14. A sliding block 15 is slidably installed in the groove 1401. A receiving plate 16 is fixed on the sliding block 15 and rotatably connected to the first support roller 17 and the second support roller 18.

[0055] In detail, when it is necessary to install the protective frame 10 on the side of the backlight module, the backlight module can be placed on the fixture 5, and the side of the backlight module that needs to install the protective frame 10 is suspended outside the fixture 5. Under the action of the limiting block, three sides of the backlight module are limited. At the same time, under the action of the air chamber 4, a negative pressure is formed in the negative pressure hole. The negative pressure will attract the backlight module to ensure that the backlight module will not be displaced.

[0056] Since the backlight module is made of flexible material, the unsupported floating free end will deform under the action of gravity, causing the protective frame 10 to be installed and misaligned with it. Therefore, it is necessary to support and limit the free end of the backlight module. In the initial state, the guide slider 12 is located at the end of the stroke of the guide post 11 away from the support plate 301, so that the distance between the guide slider 12 and the support plate 301 is the maximum. The extension of the first spring 13 in its natural state is greater than the maximum distance between the guide slider 12 and the support plate 301. Therefore, the first spring 13 is in a pre-compressed state and always provides the guide slider 12 with a thrust in the direction away from the support plate 301. At this time, the guide slider 12 will control the first support roller 17 and the second support roller 18 to be on the same vertical plane at the very end of the free end of the backlight module through the connecting plate 14, the sliding block 15, and the receiving plate 16.

[0057] Under the action of the bidirectional pressure mechanism, the two sliding blocks 15 are located at the end of the stroke on one side of the slide groove 1401, and the distance between the two sliding blocks 15 is the smallest. Under the action of the sliding blocks 15, the distance between the first support roller 17 and the second support roller 18 is controlled to be the smallest by the receiving plate 16, and it just abuts against the upper and lower sides of the free end of the backlight module, thereby supporting and limiting the free end of the backlight module, ensuring that the position of the free end of the backlight module will not shift when the protective frame 10 is connected to the backlight module.

[0058] Please see Figures 1-6 , Figures 8-13 The bidirectional pressure mechanism includes an upper support and a lower support respectively mounted on the two connecting plates 14. The upper support includes a second support column 26 fixed on one of the connecting plates 14. The second support column 26 has a third sliding plate 28 slidably connected to the sliding block 15. A third limiting post 29 is fixed on the third sliding plate 28. A guide groove is formed on the fixing plate 6 that slidably engages with the third limiting post 29. The mechanism also includes a fourth spring 27 sleeved on the second support column 26 and abutting against the third sliding plate 28.

[0059] Please see Figures 1-6 , Figures 8-12, the lower support member includes a first support column 21 fixed to another connecting plate 14. A first sliding plate 19 fixedly connected to the sliding block 15 axially slides on the first support column 21. A first limiting column 20 is fixed on the first sliding plate 19. A rectangular groove body that slidably engages with the first limiting column 20 is formed on the fixing plate 6. It further includes a guiding component and an elastic component disposed on the first support column 21 for controlling the movement of the first sliding plate 19. The guiding component includes a guiding groove body formed on the fixing plate 6. A second sliding plate 22 axially slides on the first support column 21. A second limiting column 23 fixedly connected to the guiding groove body is fixed on the second sliding plate 22. The elastic component includes a second spring 24 and a third spring 25 sleeved on the first support column 21. Two ends of the second spring 24 respectively abut against the connecting plate 14 and the first sliding plate 19. Two ends of the third spring 25 respectively abut against the first sliding plate 19 and the second sliding plate 22.

[0060] Please refer to Figures 1-4 , Figure 7 , the pushing component includes a cylinder 7 fixed to the machine table 1. A pushing plate 8 is fixed to the telescopic end of the cylinder 7. A suction cup 9 fixedly connected to the protective frame 10 is fixed on the pushing plate 8.

[0061] Please refer to Figure 7 , further, the protective frame 10 can be divided into three parts, namely an upper guard plate, a connecting guard plate, and a lower guard plate. The middle gap formed after their combination is a plugging groove body 1001. The opening of the plugging groove body 1001 is inclined, and the inside is horizontal, that is, the opening size is larger than the inside size. The upper surface of the upper guard plate is also inclined, and the length of the upper guard plate is greater than the length of the lower guard plate. Glue is filled in one side of the lower guard plate within the plugging groove body 1001;

[0062] Please refer to Figure 5 , Figure 6 , the rectangular groove body is in a rectangular shape and is composed of four groove bodies. The four groove bodies are respectively a first straight groove 601, a first vertical groove 602, a second straight groove 603, and a second vertical groove 604. The guiding groove body is composed of two groove bodies, namely a first horizontal groove 605 and an inclined groove 606. The L-shaped groove body is composed of two groove bodies, namely a second horizontal groove 607 and a third vertical groove 608. Starting from the first horizontal groove 605, the inclined direction of the inclined groove 606 faces the direction of the rectangular groove body. In the horizontal direction, the combined length of the first horizontal groove 605 and the inclined groove 606 is equal to the length of the first straight groove 601. The length of the second horizontal groove 607 is less than the length of the first straight groove 601;

[0063] Please refer to Figures 9-11For the lower support member, in the initial state, the first limiting post 20 is located at the connection position of the first straight groove 601 and the second vertical groove 604. The first limiting post 20 controls the sliding block 15 to be located at the end of its stroke on one side of the slide groove 1401 through the first sliding plate 19, and the distance between it and the guide slider 12 is the smallest. The second limiting post 23 is located at the end of its stroke on the side of the first horizontal groove 605 away from the inclined groove 606, so that the second sliding plate 22 is located at the end of its stroke on the side away from the first sliding plate 19. In this case, the distance between the first sliding plate 19 and the connecting plate 14 is the largest, and the distance between the second sliding plate 22 and the first sliding plate 19 is the largest. The second spring... The elongation of the second spring 24 in its natural state is greater than the maximum distance between the first sliding plate 19 and the connecting plate 14. The elongation of the third spring 25 in its natural state is greater than the maximum distance between the first sliding plate 19 and the second sliding plate 22. Therefore, both the second spring 24 and the third spring 25 are in a pre-compressed state. In this state, the elastic potential energy of the second spring 24 is greater than the elastic potential energy of the third spring 25. Therefore, the first sliding plate 19 is always subjected to a thrust toward the direction closer to the guide slider 12, and the second sliding plate 22 is always subjected to a thrust away from the first sliding plate 19, so that the second support roller 18 is always in contact with the lower side of the free end of the backlight module.

[0064] For the upper support member, the third limiting post 29 is located at the end of the stroke of the second horizontal groove 607 away from the third vertical groove 608, so that the third sliding plate 28 is located at the end of the stroke towards the guide slider 12. The extension of the fourth spring 27 in its natural state is greater than the length of the second support post 26. Therefore, the fourth spring 27 is in a pre-compressed state and always provides the third sliding plate 28 with a thrust towards the guide slider 12. Therefore, the first support roller 17 is always in contact with the upper side of the free end of the backlight module.

[0065] When the protective frame 10 needs to be assembled, the protective frame 10 can be placed in the position to cooperate with the suction cup 9 by the feeding machine. Under the action of the suction cup 9, the protective frame 10 is adsorbed. At the same time, under the pushing action of the cylinder 7, the protective frame 10 is controlled to move towards the free end of the backlight module by the pushing plate 8 and the suction cup 9, and the insertion groove 1001 is facing the backlight module. At this time, the temperature of the glue in the protective frame 10 is low and its adhesion is minimal.

[0066] When the protective frame 10 comes into contact with the first support roller 17 and the second support roller 18, since the first support roller 17 and the second support roller 18 tend to move towards each other, the first support roller 17 and the second support roller 18 will control the movement of the sliding block 15 through the receiving plate 16, thereby controlling the guide slider 12 to slide along the axial direction of the guide post 11 through the connecting plate 14, so that the release amount of the free end of the backlight module gradually increases. Since the insertion slot 1001 is set with an inclined opening, the released free end will gradually enter the insertion slot 1001. During this process, the first limiting post 20 will slide along the first straight groove 601, the second limiting post 23 will slide along the first transverse groove 605, and the third limiting post 29 will slide along the second transverse groove 607.

[0067] Since the free end of the backlight module is immediately inserted into the insertion slot 1001 after being released, the free end of the backlight module will not deform, ensuring that the free end of the backlight module and the insertion slot 1001 are always in a mutually cooperating position.

[0068] When the second limiting post 23 disengages from the first transverse groove 605 and enters the inclined groove 606, the inclined groove 606 and the second limiting post 23 cause the second sliding plate 22 to move towards the first sliding plate 19, compressing the third spring 25. Since the first limiting post 20 is located within the first straight groove 601, the position of the first sliding plate 19 does not change. As the second sliding plate 22 moves, the elastic potential energy of the third spring 25 will be directed towards the elastic potential energy of the second spring 24, causing the first sliding plate 19 to tend to move away from the second sliding plate 22. During this process, the third limiting post 29 moves to the connection position of the second horizontal groove 607 and the third vertical groove 608, and under the action of the inclined surface of the upper guard plate of the protective frame 10, the first support roller 17 moves away from the second support roller 18, and controls the third sliding plate 28 to slide along the axial direction of the second support post 26 and move away from the guide slider 12 to compress the fourth spring 27. Since the protective frame 10 is fixed by the suction cup 9, the downward pressure provided by the first support roller 17 to the protective frame 10 will not cause the protective frame 10 to shake.

[0069] Since the second support roller 18 remains attached to the free end of the backlight module, the adhesive adhesion between the backlight module and the protective frame 10 is relatively small, and the upper side of the backlight module is attached to the lower side of the upper guard plate of the protective frame 10, ensuring that the backlight module will not deform due to excessive adhesiveness during the insertion process.

[0070] When the protective frame 10 is inserted into place, the first limiting post 20 moves to the connection position of the first straight groove 601 and the first vertical groove 602, the second limiting post 23 moves to the end of the stroke of the inclined groove 606 away from the first horizontal groove 605, and the third limiting post 29 moves to the end of the stroke of the third vertical groove 608 away from the second horizontal groove 607. The compression of the third spring 25 reaches its maximum. The first support roller 17 is in contact with the upper surface of the protective frame 10, and the second support roller 18 is in contact with the side of the protective frame 10. At this time, the third spring 25 is released elastically and quickly controls the first sliding plate 19 to move away from the second sliding plate 22, so that the first... A limiting post 20 slides along the first vertical groove 602 and compresses the second spring 24. When the first limiting post 20 moves to the position where the first vertical groove 602 and the second straight groove 603 are connected, the second support roller 18 separates from the protective frame 10, the first spring 13 is released elastically, and the guide slider 12 is reset, so that the first limiting post 20 slides along the second straight groove 603 and the second limiting post 23 slides along the inclined groove 606, so that the third spring 25 is released elastically. During this process, the elastic potential energy of the second spring 24 will exceed the elastic release of the third spring 25 again, so that the first sliding plate 19 has a tendency to move towards the second sliding plate 22.

[0071] When the first limiting post 20 moves to the position where the second straight groove 603 and the second vertical groove 604 are connected, the second limiting post 23 returns to the end of the stroke of the first horizontal groove 605. At this time, the second spring 24 is released elastically and pushes the first sliding plate 19 to move towards the direction close to the second sliding plate 22, so that the second support roller 18 is in contact with the lower side of the protective frame 10 and provides a certain thrust to the lower side of the protective frame 10.

[0072] The second support roller 18 is equipped with a resistance heating module. Since the first support roller 17 and the second support roller 18 are respectively attached to the upper and lower sides of the protective frame 10, and under the action of the third limiting post 29 and the third vertical groove 608, the position of the first support roller 17 will not change. The elastic potential energy of the fourth spring 27 is much smaller than that of the second spring 24. Therefore, the suction cup 9 no longer adsorbs the protective frame 10. The resultant force on the protective frame 10 is directed towards the first support roller 17. Under the action of heating, the adhesive viscosity is enhanced so that the adhesive is firmly bonded to the lower side of the backlight module, ensuring the smooth installation of the protective frame 10.

[0073] Preferably, through the elastic force changes of the second spring 24 and the third spring 25, the second support roller 18 can always provide support force to the lower side of the backlight module during the insertion process of the protective frame 10, so as to ensure that the backlight module will not deform. At the same time, after the protective frame 10 is inserted into place, the second support roller 18 can automatically separate from the side of the protective frame 10 and move to the lower side of the protective frame 10 to automatically provide a pushing force to the lower side of the protective frame 10. Under the action of heating, it is ensured that the adhesive is completely bonded to the backlight module, so as to ensure that the protective frame 10 will not loosen after insertion. In this way, through the automatic adjustment of the positions of the first support roller 17 and the second support roller 18, the slow release of the free end of the backlight module and the limiting support of the protective frame 10 can be adaptively completed to ensure smooth assembly.

[0074] The application of a backlight module assembly equipment in display panel production includes the aforementioned backlight module assembly equipment.
