Description

Technical Field

[0001] This utility model belongs to the technical field of FPCA production equipment, and in particular relates to a high-efficiency FPCA sealing fixture for picking up and placing boards. Background Technology

[0002] Flexible printed circuit boards (FPCAs), due to their thinness and flexibility, have become the core circuit carrier in precision electronic products such as smartphones, smart wearable devices, and data acquisition lines for new energy battery packs in emerging industries in recent years. In the production and processing of FPCAs, encapsulation is one of the key processes. Its purpose is to improve the corrosion resistance and impact resistance of the FPCA by applying a protective adhesive layer, preventing short circuits or open circuits in the internal circuitry due to external environmental factors.

[0003] Currently, FPCA sealing operations largely rely on fixtures. Simple fixtures typically only offer basic support and positioning functions, exhibiting significant limitations in practical applications: Firstly, the support platforms of existing fixtures are mostly fixed horizontal structures, unable to adjust the tilt angle according to specific sealing requirements. This not only easily leads to uneven sealant thickness and adhesive overflow, but also significantly increases operation time and hinders FPCA placement and removal. Secondly, the FPCA positioning structure of existing fixtures lacks stability. Some fixtures use rigid clips to fix the FPCA components, which can easily scratch the components and the circuitry or solder mask layer on the FPCA surface during disassembly and assembly, further affecting FPCA placement and removal efficiency.

[0004] To address this, industry professionals have developed a high-efficiency FPCA sealing fixture for picking up and placing boards. Utility Model Content

[0005] The purpose of this utility model is to solve the problems that the support platform of existing FPCA sealing fixtures is mostly a fixed horizontal structure, which cannot adjust the tilt angle according to special sealing needs, making it inconvenient to pick up and put down. In addition, its positioning structure uses rigid buckles to fix the FPCA component part, which is easy to scratch the component and FPCA during disassembly and assembly, and is also inconvenient to pick up and put down. Therefore, a high-efficiency FPCA sealing fixture with a pick-up and put-down board is provided.

[0006] This utility model achieves the above objectives through the following technical solution: a high-efficiency FPCA sealing fixture for picking up and placing boards, including a support substrate, an angle adjustment component is provided at one end of the upper surface of the support substrate, and a number of element positioning components are evenly distributed on the angle adjustment component.

[0007] The angle adjustment assembly includes a base, with bearing seats at both ends of the upper surface of the base. A swing rod is mounted on the inner ring of each of the two sets of bearing seats. A swing platform is fixedly mounted on the swing rod. The element positioning assembly is fixed to the upper surface of the swing platform. Arc grooves are formed on both sidewalls of the swing platform. Guide bolts that mate with the arc grooves on the same side are fixedly mounted on both sidewalls of the base. Locking wrenches are provided on both sidewalls of the swing platform, and these locking wrenches engage with the end sidewalls of the base.

[0008] Furthermore, the swing table has a transition arc surface on the side facing the supporting substrate.

[0009] Furthermore, the center of the arc groove is collinear with the axis of the swing rod, the width of the arc groove is 0.2-0.5mm larger than the diameter of the guide bolt, and the end of the guide bolt is threaded with an anti-loosening nut.

[0010] Furthermore, the locking wrench includes a wrench body hinged to the side wall of the swing platform and a locking block fixed to the free end of the wrench body. The end face of the locking block is provided with anti-slip teeth. A torque spring is provided at the hinge point between the wrench body and the swing platform. The torque spring is used to provide a preload force for the locking block to press against the side wall of the base.

[0011] Furthermore, the component positioning assembly includes several sets of elastic mechanisms. A lower abutment is provided above the elastic mechanism. Guide posts are provided on both sides of the lower abutment. Upper pressing members are slidably provided on the guide posts on the same side. Each upper pressing member has a slot. The two sets of slots form a cavity.

[0012] Furthermore, the elastic mechanism includes a supporting base cylinder fixed to the swing table, a retractable rod movably disposed at the end of the supporting base cylinder, and a spring disposed between the retractable rod and the end of the supporting base cylinder.

[0013] Beneficial effects: This utility model has a reasonable design, simple and stable structure, and strong practicality, and has the following beneficial effects:

[0014] 1. Precise and convenient angle adjustment to meet diverse sealing needs: Through the rotational cooperation between the swing rod and the bearing seat, and the precise guidance of the arc groove and the guide bolt, the tilt angle of the swing table can be flexibly adjusted to meet the special sealing needs of different areas of FPCA, avoiding problems such as uneven sealing thickness, glue overflow, and inconvenience of picking up and putting down caused by fixing the horizontal platform.

[0015] 2. Stable and reliable angle locking ensures sealing stability: The locking wrench, combined with a torque spring and anti-slip toothed locking block, provides continuous preload to the adjusted swing table, effectively preventing the swing table from shifting or shaking during the sealing process, and improving the stability and accuracy of the sealing operation.

[0016] 3. Component positioning is safe and non-destructive, with strong protection: The component positioning assembly adopts an elastic mechanism with an upper pressing part and a lower abutment clamping structure. The spring provides flexible clamping force to avoid the rigid buckle from scratching the FPCA component, surface circuit, and solder mask layer. At the same time, the clamping cavity design can realize the rapid positioning and placement of FPCA. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example 1:

[0024] Combination Figure 1-2 The high-efficiency FPCA sealing fixture shown includes a support base plate 1 for providing a stable support foundation for the entire fixture. The support base plate 1 has a small flatness error to ensure the accuracy of subsequent component installation. An angle adjustment component 2 is fixedly connected to one end of the upper surface of the support base plate 1 by bolts or welding. Several sets of component positioning components 3 for positioning FPCA components are evenly distributed along the length of the angle adjustment component 2. The spacing of the multiple sets of component positioning components 3 is designed according to the size specifications of common FPCA, which can realize the simultaneous sealing operation of multiple FPCAs and greatly improve the batch processing efficiency.

[0025] The angle adjustment assembly 2 includes a base 201 fixedly connected to the support base plate 1. The base 201 is a rectangular block structure with its upper surface milled and precision machined. Bearing seats 202 are bolted to both ends of the upper surface of the base 201. The two sets of bearing seats 202 have collinear axes, and deep groove ball bearings are installed inside the bearing seats 202. These deep groove ball bearings have the characteristics of low friction coefficient and high rotational accuracy. The inner rings of the bearings in the two sets of bearing seats 202 are interference-fitted with the swing rod 203 to ensure that the swing rod 203 can rotate synchronously with the inner rings of the bearings without radial movement. A swing table 204 is fixedly connected between the two ends of the swing rod 203 to prevent relative rotation between the swing table 204 and the swing rod 203. The swing table 204 is a load-bearing structure for mounting the component positioning assembly 3. Its upper surface has mounting positions adapted to the component positioning assembly 3 to ensure that the component positioning assembly 3 does not shift during the sealing operation. Arc grooves 205 are formed on the side walls at both ends of the swing table 204. The center of the arc groove 205 is collinear with the axis of the swing rod 203. This design ensures that when the swing table 204 rotates around the swing rod 203, the arc groove 205 always maintains a fit with the guide bolt 206, preventing jamming. Guide bolts 206 that mate with the arc groove 205 on the same side are threadedly fixed on the side walls of both ends of the base 201. The threaded part of the guide bolt 206 passes through the arc groove 205, which not only ensures the flexibility of the swing table 204 during rotation but also restricts the swing through the side wall of the arc groove 205. The rotation range of the stage 204 is limited to prevent excessive rotation from damaging the components. Locking wrenches 207 are provided on both ends of the sidewall of the swing stage 204. The locking wrenches 207 cooperate with the end sidewall of the base 201. When the swing stage 204 is adjusted to the target angle, the locking wrench 207 can be pulled to press it against the end sidewall of the base 201. The position of the swing stage 204 is locked by friction, which prevents the swing stage 204 from shifting due to external force during the sealing process, and facilitates subsequent sealing and FPCA loading and unloading.

[0026] In this embodiment, the swing table 204 has a transition arc surface at the edge facing the support substrate 1, which facilitates the effective transfer of the main body of the FPCA to the support substrate 1 after it is placed on the swing table 204, avoiding damage to the surface structure of the FPCA. At the same time, it can also prevent the operator from being scratched when adjusting the angle or picking up and placing the FPCA due to the sharp edge, thus improving the safety of operation.

[0027] In this embodiment, the center of the arc groove 205 is collinear with the axis of the swing rod 203. This collinear design is key to ensuring the stable rotation of the swing table 204. Since the swing table 204 rotates around the bearing seat 202 with the swing rod 203 as the rotation axis, the alignment of the center of the arc groove 205 with the axis of the swing rod 203 ensures that the inner wall of the arc groove 205 maintains a uniform relative position with the guide bolt 206 throughout the entire angle adjustment process. This avoids one-sided friction or jamming between the arc groove 205 and the guide bolt 206 due to center offset, thereby ensuring the smoothness of the swing table 204's rotation and the accuracy of angle adjustment. The groove width of the arc groove 205 is 0.2-0.5mm larger than the screw diameter of the guide bolt 206 to prevent the arc groove 205 from jamming with the guide bolt 206. Furthermore, the end of the guide bolt 206 is threaded with an anti-loosening nut to prevent the swing table 204 from coming off due to accidental force during angle adjustment.

[0028] In this embodiment, the locking wrench 207 includes a wrench body that is rotatably connected to the side wall of the swing platform 204 via a hinge shaft. The free end of the wrench body is fixed with a locking block by welding or bolt fastening. The end face of the locking block (i.e. the surface that contacts the end side wall of the base 201) is provided with anti-slip teeth. A torque spring is also fitted at the hinge between the wrench body and the swing platform 204. One end of the torque spring is embedded in the groove of the wrench body. When the wrench body is in the working state, the torque spring will push the locking block to apply a continuous preload to the end side wall of the base 201 through its own elastic restoring force, thereby fixing the position of the swing platform 204.

[0029] In this embodiment, the component positioning assembly 3 includes several sets of elastic mechanisms 301 evenly distributed along the length of the swing table 204. The elastic mechanisms 301 provide a stable clamping force for subsequent components. Above the elastic mechanisms 301, a lower abutment 302 is provided to support the bottom of the FPCA component. The upper surface of the lower abutment 302 is polished. Guide posts 303 are vertically fixed on both sides of the lower abutment 302 by welding or threaded connection. Upper pressing members 304 for pressing the top of the FPCA component are slidably provided on both sets of guide posts 303. The upper pressing members 304 are provided with openings that are adapted to the guide posts 303. The sliding hole and the upper pressure member 304 are both provided with slots 305 for engaging the edge of the FPCA element. The two sets of slots 305 are symmetrically distributed and their openings face each other, forming a cavity for positioning the FPCA element. When installing the FPCA, the lower abutment 302 is pressed down to place the FPCA element between the two sets of slots 305. After releasing, the elastic restoring force of the elastic mechanism 301 pushes the lower abutment 302 upward, which, together with the action of the upper pressure member 304, makes the edge of the FPCA element tightly clamped in the cavity, achieving precise positioning of the FPCA and facilitating the removal and placement of the FPCA.

[0030] In this embodiment, the elastic mechanism 301 includes a support base cylinder 3011 fixed to the upper surface of the swing table 204. The support base cylinder 3011 adopts a cylindrical hollow structure. A retractable rod 3012 is movably provided at the end of the support base cylinder 3011 away from the swing table 204 (i.e., the upper end). The lower end of the retractable rod 3012 is inserted into the hollow cavity of the support base cylinder 3011, and the retractable rod 3012 can smoothly extend and retract along the axial direction of the support base cylinder 3011. A spring 3013 is provided between the retractable rod 3012 and the end of the support base cylinder 3011. The spring 3013 is a cylindrical helical compression spring, which is sleeved on the outside of the retractable rod 3012. The lower end of the spring 3013 abuts against the annular step at the end of the support base cylinder 3011, and the upper end abuts against the limiting protrusion in the middle of the retractable rod 3012. The spring 3013 forms an upward elastic support force on the FPCA, ensuring that the FPCA is tightly clamped.
