Description

Technical Field

[0001] This utility model belongs to the technical field of FPCA sealing equipment, and in particular relates to a novel connector shape positioning FPCA sealing fixture. Background Technology

[0002] In the production and processing of FPCA (flexible printed circuit board), the connection between the connector and the FPCA often needs to be sealed with glue to improve connection stability, water resistance and anti-interference ability. The quality of the sealing operation is highly dependent on the precise positioning of the connector and the FPCA, so the sealing fixture has become a key auxiliary equipment.

[0003] The following problems are commonly found in FPCA sealing fixtures currently on the market: First, poor positioning adaptability. Most fixtures adopt a fixed structure design and can only position connectors of a single specification. When the connector size and model are different, the fixture needs to be replaced, which not only increases the equipment investment cost but also frequently interrupts the production process. Second, positioning accuracy is difficult to guarantee. Some fixtures are prone to displacement during the positioning and clamping of connectors, resulting in sealing position deviation, which in turn affects the electrical performance and service life of FPCA.

[0004] Therefore, as electronic devices develop towards miniaturization and high precision, the size of FPCA and connectors continues to shrink, placing higher demands on the positioning accuracy and adaptability of encapsulation fixtures. Existing fixtures can no longer meet the current demand for efficient and high-quality FPCA encapsulation processing. Therefore, developing an FPCA encapsulation fixture that can adapt to multiple connector specifications and has high positioning accuracy has become the key to solving the current industry pain points. Utility Model Content

[0005] The purpose of this invention is to provide a new type of FPCA sealing fixture for connector shape positioning, which solves the problems of poor positioning adaptability of existing FPCA sealing fixtures, only adapting to a single specification of connector, increased cost and insufficient positioning accuracy when replacing fixtures, and easy displacement during positioning and clamping, resulting in sealing position deviation and affecting FPCA performance.

[0006] The present invention achieves the above objectives through the following technical solution: a novel connector shape positioning FPCA sealing fixture, comprising a support base plate, a rotating support platform is provided at one end of the upper surface of the support base plate, a pressure plate is rotatably provided on the rotating support platform, the rotating support platform and the pressure plate are engaged by a torsion spring, and a connector positioning component is provided on the pressure plate.

[0007] The connector positioning assembly includes a positioning base plate, on which two sets of bearing seats are arranged opposite each other. The inner rings of the bearing seats in the two sets of bearing seats are rotatably provided with bidirectional threaded rods. One end of the bidirectional threaded rod is provided with an adjusting cap. Both sets of threads of the bidirectional threaded rod are provided with ball nut seats that mate with them. Both sets of ball nut seats are provided with positioning plates. The positioning base plate is provided with a guide rail, on which two sets of guide sliders are provided. The two sets of guide sliders are respectively fixedly connected to the ball nut seats at the same end.

[0008] Furthermore, the upper surface of the support base plate is provided with an FPCA placement groove, and the inner walls of the FPCA placement groove are provided with elastic clamping strips on both sides. The elastic clamping strips are made of spring steel, and the four corners of the support base plate are provided with locking bolts for subsequent connection with the work platform.

[0009] Furthermore, the positioning base plate is provided with scale lines located between the two sets of bearing seats, and the scale lines are distributed along the length direction of the bidirectional threaded rod.

[0010] Furthermore, a clearance bushing is provided at the middle position of the bidirectional threaded rod.

[0011] Furthermore, an anti-slip bushing is fitted on the outer peripheral wall of the adjusting cap.

[0012] Furthermore, the two sets of positioning plates have an "L" shaped cross section, and the two sets of positioning plates are arranged opposite each other to form a connector positioning groove. An elastic buffer layer is attached to the inner wall of each set of positioning plates, and the thickness of the elastic buffer layer is 1-1.5mm.

[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. Improve positioning adaptability, reduce costs and ensure production continuity: Through the structural design of two sets of ball nut seats and two bi-directional threaded rods, rotating the adjusting cap can drive the two sets of positioning plates to move synchronously in opposite directions. It can adapt to connectors of different specifications, without the need to replace the entire set of fixtures, greatly reducing equipment investment costs and avoiding frequent interruptions to the production process due to fixture replacement.

[0015] 2. Improve connector positioning accuracy and ensure sealing quality: The guide rail on the positioning base plate and the guide slider connected to the ball nut seat form a guiding fit, which can limit the offset when the ball nut seat moves. At the same time, the scale lines on the positioning base plate can intuitively assist in adjusting the positioning plate spacing. Combined with the positioning groove formed by the "L" shaped positioning plate, it effectively improves the connector positioning accuracy, avoids sealing position deviation, and ensures the electrical performance and service life of FPCA.

[0016] 3. Enhance FPCA fixation stability and reduce movement during the sealing process: The FPCA placement slot on the support substrate provides a dedicated space for FPCA placement. The spring steel elastic clamping strips on both sides of the inner wall of the slot can elastically clamp the FPCA, which can firmly fix the FPCA, reduce the movement of the FPCA during the sealing process, and further ensure the stability of the sealing operation.

Detailed Implementation

[0021] 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.

[0022] Example 1:

[0023] Combination Figure 1-2 The present invention discloses a novel connector shape positioning FPCA sealing fixture, comprising a support base plate 1 for supporting the entire fixture component and providing a foundation for placing the FPCA. A rotating support platform 2 for supporting the rotation of a pressure plate 3 is fixedly installed on one end of the upper surface of the support base plate 1. The rotating support platform 2 forms a rotating engagement with one end of the pressure plate 3 through a rotating shaft, so that the pressure plate 3 can rotate around the rotating support platform 2 within a range. The rotating support platform 2 and the pressure plate 3 form an elastic pressing engagement through a torsion spring 4. Specifically, the torsion spring 4 is sleeved on the outer periphery of the rotating shaft connecting the rotating support platform 2 and the pressure plate 3, and the two ends of the torsion spring 4 abut against the side wall of the rotating support platform 2 and the lower surface of the pressure plate 3, respectively. When the pressure plate 3 is flipped upward, the torsion spring 4 undergoes elastic deformation and stores elastic potential energy. After the pressure plate 3 is released, the torsion spring 4 releases the elastic potential energy and can drive the pressure plate 3 to automatically flip downward, thereby forming a stable pressing on the FPCA on the support base plate 1. In order to achieve accurate positioning of the connector, a connector positioning component 5 is fixedly provided on the pressure plate 3.

[0024] The connector positioning assembly 5 includes a positioning base plate 501 fixedly connected to the pressure plate 3. The positioning base plate 501 serves as the mounting foundation for the connector positioning assembly 5. Two sets of bearing seats 502 for supporting the bidirectional threaded rod 503 are arranged opposite each other along its length on its upper surface. Both sets of bearing seats 502 are fixed to the positioning base plate 501 by bolts, and the inner rings of the bearings in both sets of bearing seats 502 are interference-fitted with the outer peripheral walls at both ends of the bidirectional threaded rod 503, allowing the bidirectional threaded rod 503 to rotate smoothly under the support of the two sets of bearing seats 502. To facilitate manual rotation of the bidirectional threaded rod 503, an adjusting cap 504 is fixedly installed at one end of the bidirectional threaded rod 503. Two threaded sections with opposite directions are machined on the outer peripheral wall of the bidirectional threaded rod 503. Each of the two sets of threaded sections is equipped with a ball nut seat 505 that forms a helical transmission engagement with it. When the bidirectional threaded rod 503 rotates, the two sets of ball nut seats can synchronously rotate relative to each other along the axial direction of the bidirectional threaded rod 503 under the action of the threaded transmission. Alternatively, they can move in opposite directions (i.e., simultaneously moving closer to or further away from each other). Positioning plates 506 for positioning connectors are fixedly installed on the upper surfaces of both sets of ball nut seats 505. The spacing of the positioning plates 506 can be adjusted as the ball nut seats 505 move to accommodate connectors of different widths. To prevent the ball nut seats 505 from rotating or shifting during movement and to ensure the moving accuracy of the positioning plates 506, a guide rail 507 is provided on the upper surface of the positioning base plate 501 along the length of the bidirectional threaded rod 503. Two sets of guide sliders 508 are slidably mounted on the guide rail 507. The upper surfaces of the two sets of guide sliders 508 are fixedly connected to the lower surfaces of the ball nut seats 505 at the same end. When the ball nut seats 505 move, the guide sliders 508 can slide synchronously along the guide rail 507. Through the sliding cooperation between the guide rail 507 and the guide sliders 508, a precise guide is formed for the moving direction of the ball nut seats 505, ensuring that the positioning plates 506 always move in the preset direction.

[0025] In this embodiment, to achieve precise positioning and stable placement of the FPCA during the encapsulation process, an FPCA placement groove 101 is formed along the length of the upper surface of the support substrate 1. The FPCA placement groove 101 provides dedicated placement space for the FPCA, preventing lateral movement of the FPCA on the support substrate 1. Furthermore, the groove wall's limiting effect lays the foundation for precise docking between the connector and the FPCA. To further enhance the stability of the FPCA within the FPCA placement groove 101 and to prevent damage to the flexible FPCA substrate from rigid clamping, springs are fixedly installed on both sides of the inner wall of the FPCA placement groove 101. The elastic clamping bar 102 is made of spring steel, which has excellent elastic deformation capacity and fatigue strength. It can maintain stable elastic performance during long-term clamping operations. In order to ensure that the entire fixture remains relatively fixed to the external work platform during the sealing operation and to avoid affecting the sealing accuracy due to fixture displacement, locking bolts 103 are provided through the four corners of the support base plate 1 for subsequent connection with the work platform. The fastening force of the threaded connection firmly fixes the support base plate 1 to the work platform, ensuring the positional stability of the fixture throughout the sealing operation cycle, thereby ensuring the consistency and accuracy of the sealing process.

[0026] In this embodiment, to achieve precise control over the spacing between the two sets of positioning plates, and to facilitate quick adjustment by staff to the size that matches the connector specifications, while reducing repeated calibration steps, the upper surface of the positioning base plate 501 is located between the two sets of bearing seats 502, and clear scale lines are printed along the length direction of the bidirectional threaded rod 503. These scale lines are symmetrically distributed with the central axis of the bidirectional threaded rod 503 as the reference line, and the scale accuracy can reach 0.1mm, which can meet the high precision requirements of different connector specifications for positioning spacing.

[0027] In this embodiment, to prevent the two sets of ball nut seats 505 from colliding with each other during movement along the bidirectional threaded rod 503, and to provide protection for the middle part of the bidirectional threaded rod 503, a clearance bushing 509 is fitted at the middle position of the bidirectional threaded rod 503. From the working principle, when the operator rotates the adjusting cap 504 to drive the bidirectional threaded rod 503 to rotate, the two sets of ball nut seats 505 move synchronously under the action of threaded transmission. If it is necessary to reduce the distance between the two sets of positioning plates 506 (to adapt to small-size connectors), the two sets of ball nut seats 505 will move closer to the middle of the bidirectional threaded rod 503. When they move to the preset limit position, the ball nut seats 505 will contact the clearance bushing 509. The clearance bushing 509 blocks the ball nut seats 505 from continuing to move through its own structure, thus playing a mechanical limiting role.

[0028] In this embodiment, to improve the ease of operation for workers when rotating the adjusting cap 504 and to prevent slippage due to insufficient friction when the hand contacts the outer peripheral wall of the adjusting cap 504, thereby ensuring that the bidirectional threaded rod 503 can rotate stably to adjust the positioning plate spacing, an anti-slip bushing is tightly fitted on the outer peripheral wall of the adjusting cap 504. This bushing not only fits tightly against the outer peripheral wall of the adjusting cap 504 through its own elasticity, but also generates sufficient friction when in contact with the hand.

[0029] In this embodiment, to achieve multi-directional limiting of the connector and ensure that the connector does not shift during the sealing process, the cross-sections of both sets of positioning plates 506 are designed as "L"-shaped structures. This structure is formed by the vertical connection of horizontal and vertical sections. The horizontal section is used to contact the connector surface, and the vertical section is used to block the sides of the connector. The "L"-shaped corner structure can form a bidirectional positioning constraint on the connector, and the two sets of positioning plates 506 are arranged opposite to each other. The vertical sections of one set of positioning plates 506 face each other, while the horizontal sections of the two sets of positioning plates 506 are at the same level. The two sets of positioning plates 506, together, form a connector positioning groove that adapts to the shape of the connector. The size of the groove can be adjusted according to the spacing between the two sets of positioning plates 506 to accommodate connectors of different lengths and widths. To avoid hard contact between the positioning plates 506 and the connector, which could cause scratches on the connector shell or deformation of the pins, an elastic buffer layer 5010 is fitted onto the inner walls of both sets of positioning plates 506 (i.e., the upper surface of the horizontal section of the "L"-shaped structure and the inner sidewall of the vertical section). The thickness of the elastic buffer layer 5010 is set to 1-1.5mm, which ensures buffering performance without reducing positioning accuracy due to excessive thickness.
