Description

Technical Field

[0001] This utility model relates to the field of semiconductor processing technology, and in particular to a drive backplane fixture. Background Technology

[0002] During the manufacturing process of silicon-based OLED structures, short circuits may occur in the solder joints of components. Therefore, after the silicon-based OLED structure is fabricated, it needs to be scanned using laser repair equipment. The silicon-based OLED structure includes a driver backplane and OLED devices. The laser repair equipment primarily scans the driver backplane to repair any short circuits in the solder joints of the components on it. When scanning the driver backplane using the laser repair equipment, a fixture is required to clamp and fix the driver backplane for easy scanning.

[0003] Currently, drive backplanes include FPC boards and PCB boards. Because multiple components are soldered to the bottom of the PCB board, and these components vary in height, a fixture needs to be designed for each silicon-based OLDE product designed using a PCB board, taking into account the layout and height differences between the components. Silicon-based OLDE products come in various specifications, requiring the design of fixtures for different specifications, resulting in excessively high production costs.

[0004] Therefore, there is an urgent need for a drive backplate fixture to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this utility model is to provide a drive backplate fixture that can clamp drive backplates of various specifications, effectively solving the problem that every time a silicon-based OLDE product is designed using a drive backplate, a fixture needs to be designed according to the layout and height difference between multiple components, resulting in excessively high production costs for silicon-based OLDE products.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A drive backplate fixture, comprising:

[0008] A substrate having clearance holes formed thereon;

[0009] The system includes a drive mechanism, a first stop block, and a second stop block. The first stop block is located on one side of the clearance hole. The drive mechanism is connected to the substrate. The second stop block is driven to the drive mechanism and is opposite to the first stop block. The drive mechanism enables the second stop block to move closer to the first stop block.

[0010] The side stop and the telescopic member are provided. The telescopic member is connected to the base plate through a connecting plate. The telescopic member is located on one side of the first stop and the second stop along the second direction. The side stop is provided at the output end of the telescopic member. The telescopic member enables the side stop to be selectively placed in the clearance hole.

[0011] As a preferred technical solution for the drive backplate fixture, the drive mechanism includes a drive member and a support plate. The drive member can drive the support plate to move. The second stop is placed on the support plate. The support plate includes a folded edge opposite to the second stop. The drive backplate fixture also includes an elastic member that connects the folded edge and the second stop.

[0012] As a preferred technical solution for driving the backplate fixture, multiple elastic elements are provided, and each of the multiple elastic elements is connected to the folded edge and the second stop block, and the multiple elastic elements are spaced apart.

[0013] As a preferred technical solution for driving the backplate fixture, the elastic element is a spring.

[0014] As a preferred technical solution for the drive backplate fixture, the first stop block has a first slot on the side opposite to the second stop block, and the second stop block has a second slot opposite to the first slot. The width of both the first slot and the second slot is greater than the thickness of the drive backplate.

[0015] As a preferred technical solution for driving the backplate fixture, both the first stop and the second stop have chamfers at the ends opposite to the side stop.

[0016] As a preferred technical solution for the drive backplate fixture, the drive backplate fixture further includes a guide member, which is connected to the bottom surface of the substrate and laid along the direction of movement of the second stop block, and the guide member is guided and cooperated with the drive member.

[0017] As a preferred technical solution for driving the backplate fixture, the driving component includes a motor, a screw, and a moving block. The motor is placed on the base plate and driven by the screw. The screw is located below the base plate. The moving block is threadedly connected to the screw and placed in the clearance hole. The guide component includes a guide groove, and a portion of the moving block is placed in the guide groove.

[0018] As a preferred technical solution for the drive backplate fixture, the guide includes a guide plate and two connecting blocks. The guide plate is placed between the two connecting blocks. Each of the two connecting blocks is provided with a through hole, and each of the two through holes is provided with a bearing. The screw includes an assembly area at both ends and a threaded area in the middle. The two assembly areas are respectively placed on the inner rings of the two bearings, and the threaded area is threadedly connected to the moving block.

[0019] As a preferred technical solution for the drive backplate fixture, the connecting plate is connected to the bottom surface of the substrate. The connecting plate includes connecting areas at both ends and a groove area in the middle. The connecting areas are connected to the substrate, and the groove area faces the clearance hole. The body of the telescopic member is connected to the bottom surface of the groove area. The output end of the telescopic member passes through the groove area and faces the clearance hole. The depth of the groove area is greater than the thickness of the side stop.

[0020] The beneficial effects of this utility model are as follows:

[0021] 1. By setting clearance holes on the substrate, and setting a first stop and a second stop on opposite sides of the clearance holes, and driving the second stop to drive the second stop closer to the first stop, the distance between the first stop and the second stop can be adjusted under the action of the driving mechanism. Therefore, different specifications of drive backplates can be clamped between the first stop and the second stop. At the same time, multiple components of different heights soldered on the drive backplate can be placed in the clearance holes. It is not necessary to design corresponding fixtures according to the different layouts and specifications of the components in the drive backplate, which effectively solves the problem of high production cost of silicon-based OLDE products.

[0022] 2. By setting telescopic components on the second-direction sides of the first and second blocks, and assembling the side blocks at the output end of the telescopic components, the telescopic components allow the side blocks to selectively enter the clearance holes. That is, the side blocks can selectively be located on one side of the first and second blocks in the second direction. When the inspector places the drive backplate, the first and second blocks can position the drive backplate in the first direction. The inspector operates the telescopic components to place the side blocks in the clearance holes, and the side of the drive backplate abuts against the side blocks. The side blocks can position the drive backplate in the second direction, ensuring that each drive backplate is placed in the same position for scanning, thereby improving the accuracy of the laser repair equipment's scanning results for the drive backplate.

[0030] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0031] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0033] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0034] like Figures 1 to 3As shown in the illustration, this embodiment provides a driving backplate fixture for clamping and fixing the driving backplate in a silicon-based OLED product, so that a laser repair device can repair the short circuit locations of the components soldered in the driving backplate. The driving backplate fixture includes a substrate 1, a driving mechanism 2, a first stop 3, a second stop 4, a side stop 5, and a telescopic component 6. The substrate 1 has a clearance hole 11, and the first stop 3 is located on one side of the clearance hole 11. The driving mechanism 2 is connected to the substrate 1, and the second stop 4 is drivenly connected to the driving mechanism 2 and opposite to the first stop 3. The driving mechanism 2 can move the second stop 4 closer to the first stop 3. The driving backplate can be placed between the first stop 3 and the second stop 4. Since the distance between the first stop 3 and the second stop 4 can be adjusted by the driving mechanism 2, driving backplates of different sizes and specifications can be clamped. Multiple components of different heights soldered onto the driving backplate can be placed within the clearance hole 11, eliminating the need to design corresponding fixtures based on the layout and specifications of the components in the driving backplate, effectively solving the problem of high production costs for silicon-based OLED products.

[0035] The telescopic component 6 is connected to the base plate 1 via the connecting plate 9. The telescopic component 6 is located on one side of the first stop 3 and the second stop 4 along the second direction. The side stop 5 is set at the output end of the telescopic component 6, that is, the side stop 5 is located on one side of the first stop 3 and the second stop 4 along the second direction. The telescopic component 6 allows the side stop 5 to be selectively placed in the clearance hole 11. When the inspector places the drive backplate between the first stop 3 and the second stop 4, the inspector then controls the telescopic component 6 to place the side stop 5 in the clearance hole 11, so that the drive backplate abuts against the side stop 5. At this time, the first stop 3 and the second stop 4 achieve positioning of the drive backplate in the first direction, and the side stop 5 achieves positioning of the drive backplate in the second direction, ensuring that each drive backplate is placed in the same position for scanning, thereby improving the accuracy of the laser repair equipment's scanning results of the drive backplate. After the laser repair equipment has scanned the drive backplate and the inspector has repaired it, the inspector can operate the telescopic component 6 to move the side stop 5 downwards. At this point, the inspector can quickly remove the drive backplate through the released position of the side stop 5. In this embodiment, the first direction is the Y-axis direction, and the second direction is the X-axis direction.

[0036] In this embodiment, the telescopic component 6 can be a telescopic cylinder.

[0037] In this embodiment, the driving mechanism 2 includes a driving component 21 and a support plate 22. The driving component 21 can drive the support plate 22 to move. The second stop 4 is placed on the support plate 22. When the driving component 21 moves the support plate 22, it can also drive the second stop 4 to move. The support plate 22 includes a folded edge 221 opposite to the second stop 4. The driving backplate fixture also includes an elastic element 7, which connects the folded edge 221 and the second stop 4. Different driving backplates in the same batch have tolerances. After the inspector adjusts the distance between the first stop 3 and the second stop 4 according to the size of the driving backplate, the driving backplate can be placed between the first stop 3 and the second stop 4 and clamped and fixed. When a driving backplate with tolerances is placed, the elastic element 7 is compressed, avoiding the need for the inspector to frequently adjust the distance between the first stop 3 and the second stop 4. The setting of the elastic element 7 can solve the problem of tolerances between different driving backplates in the same batch, further improving the rationality of the driving backplate fixture design. Meanwhile, due to the presence of the elastic element 7, when the testing personnel adjust the distance between the first stop 3 and the second stop 4, they can appropriately reduce the distance between them based on the width data of the drive back plate. After placing the drive back plate, the elastic element 7 is in a compressed state, so that the first stop 3 and the second stop 4 can clamp the drive back plate more securely.

[0038] Furthermore, multiple elastic elements 7 are provided, each connected to the folded edge 221 and the second stop 4, and the multiple elastic elements 7 are spaced apart. This makes the overall force more stable when the drive back plate is clamped and fixed, further improving the rationality of the drive back plate fixture design. In this embodiment, the elastic element 7 is a spring.

[0039] In this embodiment, a first slot is provided on the side of the first stop block 3 opposite to the second stop block 4, and a second slot is provided on the second stop block 4 opposite to the first slot. The width of the first slot and the second slot is greater than the thickness of the drive back plate. When placing the drive back plate, the inspector can place it in the first slot and the second slot, so that the drive back plate is in a flat position after placement, further improving the scanning accuracy of the laser repair equipment.

[0040] Furthermore, a chamfer is provided at the end of the first stop block 3 and the second stop block 4 away from the side stop block 5. When the inspector places the drive backplate, the chamfer can play a certain guiding role, so that the inspector can quickly and conveniently place the drive backplate between the first stop block 3 and the second stop block 4.

[0041] In this embodiment, the drive backplate also includes a guide member 8. The guide member 8 is connected to the bottom surface of the substrate 1 and is laid along the direction of movement of the second stop 4. The guide member 8 is guided and engaged with the drive member 21. When the drive member 21 drives the support plate 22 to move, the guide member 8 guides the movement of the support plate 22, reducing the risk of the second stop 4 deviating during its approach to the first stop 3, and further improving the stability of the first stop 3 and the second stop 4 in clamping and fixing the drive backplate.

[0042] Exemplarily, the driving component 21 includes a motor 211, a screw 212, and a moving block 213. The motor 211 is mounted on the substrate 1 and is driven by the screw 212. The motor 211 drives the screw 212 to rotate. The screw 212 is located below the substrate 1, while the guide 8 is located on the back side of the substrate 1. Thus, when the driving backplate is clamped between the first stop 3 and the second stop 4, the screw 212 and the guide 8 will not interfere with the components on the driving backplate, making the layout of the driving backplate fixture reasonable. The moving block 213 is threadedly connected to the screw 212 and is placed in the clearance hole 11. When the motor 211 drives the screw 212 to rotate, the moving block 213 moves along the screw 212. The guide 8 includes a guide, and a portion of the moving block 213 is placed in the guide groove. The moving block 213 moves along the guide groove, realizing the guiding engagement between the guide 8 and the driving component 21.

[0043] Furthermore, the guide member 8 includes a guide plate and two connecting blocks. The guide plate is positioned between the two connecting blocks. Specifically, both connecting blocks are located on the back side of the base plate 1 and are positioned opposite each other, with one connecting block located below the first stop block 3. Both connecting blocks have through holes, and each through hole contains a bearing. The screw 212 includes assembly areas at both ends and a threaded area in the middle. The two assembly areas are respectively positioned within the inner rings of the two bearings, and the threaded area is threadedly connected to the moving block 213. Thus, by connecting both ends of the screw 212 to the bearings, when the motor 211 drives the screw 212 to rotate, the rotation of the screw 212 is more stable, thereby enabling the second stop block 4 to move more smoothly towards the first stop block 3. A guide groove 81 is provided on the guide plate.

[0044] Regarding the connection between the telescopic component 6 and the substrate 1, specifically, the connecting plate 9 is connected to the bottom surface of the substrate 1. The connecting plate 9 includes connecting areas 91 at both ends and a recessed area 92 in the middle. The connecting areas 91 are connected to the substrate 1, and the recessed area 92 faces the clearance hole 11. The main body of the telescopic component 6 is connected to the bottom surface of the recessed area 92, and the output end of the telescopic component 6 passes through the recessed area 92 and faces the clearance hole 11. This makes the layout of the telescopic component 6 more reasonable and facilitates its installation. Preferably, the depth of the recessed area 92 is greater than the thickness of the side stop 5. After the laser repair equipment completes scanning of the drive backplate, the side stop 5 can move down into the recessed area 92, enabling quick removal of the drive backplate.

[0045] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
