Description

Technical Field

[0001] This utility model relates to the field of electronic product technology, specifically to a pasting fixture and a screen pasting device. Background Technology

[0002] In the manufacturing of electronic products, especially for small-batch production, the bonding of the screen to the PCB board is usually done manually. However, due to the limitations of manual operation, significant bonding errors are unavoidable.

[0003] Manual pasting makes it difficult to ensure consistent placement each time, leading to significant deviations in the distance between the display area and the bezel. This compromises product consistency and impacts market competitiveness. Furthermore, manual pasting requires considerable time and effort for alignment and calibration, resulting in low production efficiency and increased costs. Additionally, pasting errors can cause poor contact between the screen and the PCB board, affecting the functional stability and lifespan of the electronic product.

[0004] These problems not only degrade the user experience but also impact the product's market competitiveness. Therefore, a technical solution is urgently needed to improve adhesion accuracy, ensure product consistency, and enhance production efficiency to address these issues. Utility Model Content

Because the PCB board and screen can remain stable in the predetermined positions, the errors that may occur during bonding are greatly reduced. This not only improves bonding accuracy but also ensures the consistency of product appearance and functional stability.

[0008] Because the positions of the PCB board positioning groove and the screen positioning groove can be adjusted according to different models of electronic products, it is applicable to PCB boards and screens of various sizes and shapes, with high adaptability and strong versatility. This allows the same set of fixtures to be used on different small-batch production lines, reducing production costs.

[0009] Furthermore, the PCB board positioning structure and screen positioning structure enable mechanical positioning of the PCB board and screen, ensuring consistent position and orientation with each bonding process, significantly improving product consistency. Even under manual operation, product quality stability and reliability are guaranteed.

[0014] In one alternative embodiment, the PCB board positioning block includes a first mounting portion and a first abutting portion connected to each other. The first mounting portion cooperates with the PCB board positioning slide groove and is detachably connected to the PCB board positioning slide groove by fasteners. The first abutting portion is adapted to abut against the side of the PCB board.

[0015] In one optional embodiment, the screen positioning block includes a second mounting portion, an extension portion, and a second abutment portion connected in sequence. The second mounting portion and the second abutment portion are respectively connected to opposite sides of the extension portion. The second mounting portion cooperates with the screen positioning slide groove and is detachably connected to the screen positioning slide groove by fasteners. The second abutment portion is adapted to abut against the side of the screen. The top of the second abutment portion is higher than the top of the first abutment portion.

[0016] In one alternative embodiment, the distance between the surface of the second abutment portion facing the base and the base is greater than the thickness of the PCB board.

[0035] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0036] The following is combined Figures 1 to 12 The following describes embodiments of the present invention.

[0037] According to an embodiment of the present invention, in a first aspect, a bonding fixture is provided, comprising a base 1, a PCB board positioning structure 2, and a screen positioning structure 3. The PCB board positioning structure 2 includes at least three PCB board positioning grooves 21 and at least three PCB board positioning blocks 22. The PCB board positioning grooves 21 are disposed on the base 1, and each PCB board positioning block 22 is adjustablely disposed on the PCB board positioning groove 21. The three PCB board positioning blocks 22 are adapted to abut against three sides of a PCB board 5, respectively. The screen positioning structure 3 includes at least three screen positioning grooves 31 and at least three screen positioning blocks 32. The screen positioning grooves 31 are disposed on the base 1, and each screen positioning block 32 is adjustablely disposed on the screen positioning groove 31. The screen positioning blocks 32 are adapted to abut against three sides of a screen 6.

[0038] The bonding fixture provided by this utility model, by setting multiple adjustable PCB board positioning grooves 21 and screen body positioning grooves 31 on the base 1, and in conjunction with position-adjustable positioning blocks, can limit the PCB board 5 and screen body 6 at multiple points, ensuring precise positioning of the PCB board 5 and screen body 6 during the bonding process and avoiding bonding deviations caused by manual operation. Since the PCB board 5 and screen body 6 can remain stable in the predetermined positions, the errors that may occur during the bonding process are greatly reduced. This not only improves bonding accuracy but also ensures the consistency of the product's appearance and functional stability.

[0039] Since the positions of the PCB board positioning slide 21 and the screen positioning slide 31 can be adjusted according to different models of electronic products, they are applicable to PCB boards 5 and screens 6 of various sizes and shapes. They have high adaptability and strong versatility, allowing the same set of fixtures to be used on different small-batch production lines, thus reducing production costs.

[0040] Furthermore, the PCB board positioning structure 2 and the screen positioning structure 3 enable mechanical positioning of the PCB board 5 and the screen 6, ensuring consistent position and orientation with each bonding process, significantly improving product consistency. Even under manual operation, the stability and reliability of product quality are guaranteed. Additionally, the improved bonding precision results in a more uniform distance between the screen 6 and the frame, enhancing the product's aesthetics and user experience, and boosting its market competitiveness.

[0041] In some embodiments, the PCB board positioning groove 21 and the screen positioning groove 31 do not overlap.

[0042] In some embodiments, two PCB board positioning grooves 21 of the PCB board positioning structure 2 are spaced apart along a first direction, and a third PCB board positioning groove 21 of the PCB board positioning structure 2 is spaced apart along a second direction; two screen positioning grooves 31 of the screen positioning structure 3 are spaced apart along a first direction, and a third screen positioning groove 31 of the screen positioning structure 3 is spaced apart along a second direction; the third PCB board positioning groove 21 and the third screen positioning groove 31 are located on the same side or opposite sides.

[0043] By arranging two PCB board positioning grooves 21 spaced apart along the first direction, the two PCB board positioning blocks 22 can abut against the opposite sides of the PCB board 5, achieving stable positioning of the PCB board 5 along the first direction. Simultaneously, a PCB board positioning groove 21 is added in the second direction, where the PCB board 5 can abut against and limit one side of the PCB board 5 along the second direction, thus achieving positioning of all three sides of the PCB board 5. Similarly, three screen positioning blocks 32 can abut against the three sides of the screen body 6, achieving positioning of the screen body 6. The first and second directions can be adjusted according to the shapes of the PCB board 5 and the screen body 6.

[0044] Since both the screen positioning groove 31 and the PCB board 5 limiting groove are located on the first side along the second direction, an entrance and exit are formed on one side of the pasting fixture. After the PCB board 5 and the screen 6 are pasted, the product can be slid out of the positioning area along the second direction from this entrance and exit. During the next pasting, the PCB board 5 can be directly slid into the positioning area through this entrance and exit without having to readjust the positions of the PCB board positioning block 22 and the screen positioning block 32, thereby further improving the pasting efficiency of the PCB board 5 and the screen 6.

[0045] In some embodiments, the first direction and the second direction are perpendicular.

[0046] In this embodiment, both the PCB board 5 and the screen 6 are rectangular, and the first direction and the second direction are perpendicular to each other. The first direction is one of the length direction and the width direction of the PCB board 5, and the second direction is the other of the length direction and the width direction.

[0047] In some embodiments, at least two screen positioning grooves 31 are provided along the second direction, and are distributed on both sides of the PCB board positioning block 22 along the first direction.

[0048] This configuration allows for multi-point positioning of the screen 6's sides, which is particularly suitable for larger screens and ensures precise alignment between the screen 6 and the PCB board 5 during the bonding process. It avoids the misalignment that might occur with single-point positioning on one side of the screen 6, thus further improving its positioning accuracy. Simultaneously, it guarantees consistency in each bonding operation. This not only improves the product's aesthetics and functional stability but also reduces the scrap rate during production.

[0049] In some embodiments, when the PCB board 5 is clamped, the top of the PCB board positioning block 22 is not higher than the top surface of the PCB board 5; when the screen body 6 is clamped, the top of the screen body positioning block 32 is higher than the top surface of the PCB board 5 but not higher than the top surface of the screen body 6.

[0050] Since the top of the PCB positioning block 22 is not higher than the top surface of the PCB board 5, interference between the PCB positioning block 22 and components or connectors on the PCB board 5 can be avoided, ensuring that the PCB board 5 can be smoothly inserted and removed. This not only improves assembly efficiency but also reduces the risk of damage. At the same time, it also prevents interference between the PCB positioning block 22 and the screen body 6.

[0051] Furthermore, since the top of the screen positioning block 32 is higher than the top surface of the PCB board 5, the screen positioning block 32 can avoid interference with the PCB board 5. At the same time, the top of the screen positioning block 32 is not higher than the top surface of the screen 6, thereby ensuring that the screen positioning block 32 also does not interfere with the screen 6.

[0052] In some embodiments, the PCB board positioning block 22 includes a first mounting portion 221 and a first abutting portion 222 connected to each other. The first mounting portion 221 cooperates with the PCB board positioning slide groove 21 and is detachably connected to the PCB board positioning slide groove 21 by fastener 4. The first abutting portion 222 is adapted to abut against the side of the PCB board 5.

[0053] By abutting the first contact part 222 against the side of the PCB board 5, the precise positioning of the PCB board 5 during the production process can be ensured, which helps to reduce human error that may occur during assembly and improve the overall quality of the product.

[0054] Since the first mounting part 221 cooperates with the PCB board positioning slide 21 and can be connected by fasteners 4, the position of the positioning block can be quickly adjusted as needed, which is highly flexible and can adapt to the positioning of PCB boards 5 of different sizes, thus improving the adaptability of the production line.

[0055] Since the positioning block is connected to the PCB board positioning groove 21 by fastener 4, it is easy to disassemble and maintain, and can be reused, which helps to reduce production costs.

[0056] The PCB board positioning block 22 is L-shaped. Mounting holes are provided in the first mounting part 221 to facilitate the installation of fasteners 4.

[0057] In some embodiments, the screen positioning block 32 includes a second mounting portion 321, an extension portion 322, and a second abutment portion 323 connected in sequence. The second mounting portion 321 and the second abutment portion 323 are respectively connected to opposite sides of the extension portion 322. The second mounting portion 321 cooperates with the screen positioning slide groove 31 and is detachably connected to the screen positioning slide groove 31 by fastener 4. The second abutment portion 323 is adapted to abut against the side of the screen 6. The top of the second abutment portion 323 is higher than the top of the first abutment portion 222.

[0058] The second abutment part 323 is adapted to abut against the side of the screen body 6, ensuring the precise positioning of the screen body 6 during the assembly process and helping to ensure the quality and consistency of the final product.

[0059] By engaging the second mounting part 321 with the screen positioning slide 31 and connecting it with fasteners 4, the position of the positioning block can be adjusted according to different screen sizes 6, thus improving production flexibility. Furthermore, the detachable connection using fasteners 4 facilitates adjustment or maintenance.

[0060] In this embodiment, the screen positioning block 32 has an overall Z-shaped structure. The second mounting part 321 has mounting holes to facilitate the installation of fasteners 4.

[0061] In some embodiments, the distance between the surface of the second abutment portion 323 facing the base 1 and the base 1 is greater than the thickness of the PCB board 5.

[0062] This configuration allows for a sliding gap between the second abutment 323 and the base 1, facilitating the insertion and removal of the PCB board 5 while preventing interference between the second abutment 323 and the PCB board 5, thus avoiding damage to the PCB board 5.

[0063] In some embodiments, the PCB board positioning slide 21 and the screen positioning slide 31 are provided with a plurality of spaced adjustment holes, and the first mounting part 221 and the second mounting part 321 are provided with mounting holes adapted to the adjustment holes. The fastener 4 passes through the mounting hole and is connected to the corresponding adjustment hole.

[0064] By installing the PCB board positioning block 22 and the screen positioning block 32 at different adjustment hole positions, the positioning of PCB boards 5 and screens 6 of various sizes can be accommodated. The cooperation between the fastener 4 and the adjustment hole ensures that the positioning block is firmly fixed in the required position, preventing displacement caused by vibration or other external forces during production, and improving the stability of the entire assembly process.

[0065] By setting adjustment holes, the position of the adjustment holes and the spacing between adjacent adjustment holes can be reasonably set according to the product size on the production line. In this way, the staff only needs to fix the PCB board positioning block 22 and the screen positioning block 32 into the adjustment holes, which greatly simplifies the operation process and improves production efficiency. At the same time, it can reduce the human error that may occur during manual adjustment, ensuring product consistency and quality.

[0066] During the bonding process between PCB board 5 and screen 6, first determine and install the position of PCB board positioning block 22, such as... Figure 2 As shown, then PCB board 5 is... Figure 2 The lower inlet and outlet are pushed upwards, causing the upper, left, and right sides of PCB board 5 to abut against the three PCB board positioning blocks 22, thus placing PCB board 5 in place. Figure 6 and Figure 7 As shown. At this point, adjust the position of the screen positioning block 32 according to the reserved silkscreen 51 position on the PCB board 5, so that the end face of the screen positioning block 32 used for positioning is flush with the silkscreen 51. Then place the screen 6 on the PCB board 5, with the upper side, left side and right side of the screen 6 abutting against three or four screen positioning blocks 32 respectively. The screen 6 is then in place, as shown. Figures 8 to 12 As shown. After pasting, simply pull the product straight out from the bottom inlet / outlet. The next PCB board 5 can be pushed straight up from the inlet / outlet until the upper side of the PCB board 5 abuts against the PCB board positioning block 22, that is, the PCB board 5 is in place... This can improve production efficiency.

[0067] The bonding fixture provided in this embodiment of the invention can flexibly adjust the positions of the PCB board positioning block 22 and the screen positioning block 32 according to different product sizes, thus having extremely wide adaptability. This high adaptability enables the bonding fixture to play a role in the production of products with various specifications, greatly improving the utilization rate of the bonding fixture, thereby reducing production costs and giving enterprises a greater advantage in fierce market competition.

[0068] In some embodiments, the screen and the PCB board are bonded together by double-sided adhesive strips 7.

[0069] Secondly, this utility model also provides a screen pasting device, including the pasting fixture in the above technical solution.

[0070] Beneficial effects: Since the screen bonding equipment includes bonding fixtures, it has all the technical effects of bonding fixtures, which will not be elaborated here.
