[0002] With the continuous development of electronic technology, especially the high-speed development and wide application of large-scale and ultra-large-scale integrated circuits, the demand for FPC boards (flexible printed circuit boards) is also increasing. FPC boards almost appear in every kind of electronic device, and the electronic components inside various electronic devices are all embedded on FPC boards of different sizes. High-quality FPC boards are crucial for improving the quality of electronic products.

[0003] When processing existing FPC boards, different components need to be stacked and aligned in sequence, and then formed by a press at a certain temperature and pressure. When the press presses the FPC board, it is necessary to adjust the positional relationship between the pressure head and the FPC board to ensure that the pressure head can be directly opposite the pressing point of the FPC board when pressing the FPC board. However, even after the positional relationship between the pressure head and the pressing point of the FPC board is adjusted, there is still a problem of poor process consistency during the actual pressing process. Based on this, this solution provides a single-point pressing fixture mechanism to solve the above-mentioned problems. Content of the Utility Model

[0021] Refer to Figures 1-4 As shown, a single-point pressing fixture mechanism includes an upper mold 1 and a lower mold 2. The upper mold 1 is composed of a lower pressure plate 101 and a positioning plate 102. To ensure the position accuracy, the positioning plate 102 is added to assist the upper mold 1 in positioning. A plurality of groups of positioning guide rods 3 are slidably installed at the upper end of the lower pressure plate 101. The other ends of the plurality of groups of positioning guide rods 3 are fixedly connected to the positioning plate 102. A plurality of groups of through grooves are formed on the surface of the positioning plate 102, and a mounting seat 5 and a fixed slider 7 are arranged inside the through grooves. One end of the mounting seat 5 is slidably connected to the fixed slider 7. The fixed slider 7 is fixedly installed on the surface of the positioning plate 102 through a fastening bolt. An upper mold pressing head 6 is fixedly installed at one end of the mounting seat 5 close to the positioning plate 102. A pressure sensor 9 is arranged at one end of the mounting seat 5 close to the lower pressure plate 101. The other end of the pressure sensor 9 is fixedly connected to the lower pressure plate 101. When closing the mold, the upper mold 1 drives the lower pressure plate 101 to press down through a pressing mechanism. The positioning plate 102 is fixedly connected to the external frame, so that the lower pressure plate 101 presses against the inner wall of the cavity 501 through the stabilizing rod 503, and then drives the mounting seat 5 to drive the upper mold pressing head 6 to move towards the lower mold pressing head 202. At the same time, through the cooperation of the slide rail 502 and the chute 701, the mounting seat 5 is slidably connected to the fixed slider 7, and the chute 701 plays a role in fixing the slide rail 502 to prevent the slide rail 502 from shaking during the working process, so as to ensure that during the pressing process of the upper mold 1 and the lower mold 2 on the FPC board, the relative standard deviation value generated by the shaking of the pressing fixture between the upper mold 1 and the lower mold 2 can be reduced.

[0022] Specifically, in this embodiment, a pair of handheld handles 201 are symmetrically installed at the front end of the lower mold 2. A plurality of groups of lower mold pressing heads 202 are arranged at the upper end of the lower mold 2. Lower mold positionings 10 are arranged at the four corners of the upper end of the lower mold 2. To ensure the position accuracy, the lower mold positioning 10 is added to assist the lower mold 2 in positioning. At the same time, a pair of handheld handles 201 are provided to facilitate manual picking and placing of the lower mold. The handheld handles 201 are covered with an insulating and heat-insulating sleeve.

[0023] Specifically, in this embodiment, several groups of buffer fixators 4 are fixedly installed inside the positioning plate 102, and the several groups of buffer fixators 4 are evenly linearly arranged in three groups. The buffer fixator 4 is a device composed of a spring and a shock-absorbing material that can buffer impacts and vibrations. In addition to alleviating impacts and vibrations, it can also ensure the overall stability of the upper mold 1 assembly; to reduce the relative standard deviation value generated by the upper mold 1 and the lower mold 2 due to the shaking of the pressing fixture.

[0024] Specifically, in this embodiment, a cavity 501 is opened at one end of the mounting seat 5, and a slide rail 502 is fixedly connected to the other end of the mounting seat 5. During the pressing process, the stabilizing rod 503 is squeezed and abuts against the inner wall of the cavity 501 of the mounting seat 5, so that the stabilizing member 503 plays a constraining role on the mounting seat 5 during the pressing process, preventing the mounting seat 5 from shaking during the working process.

[0025] Specifically, in this embodiment, a chute 701 is opened at one end of the fixed slider 7 close to the slide rail 502, and the shape and size of the chute 701 are both matched with the slide rail 502. Through the cooperation of the slide rail 502 and the chute 701, the mounting seat 5 is slidably connected to the fixed slider 7, and the chute 701 plays a fixing role on the slide rail 502, preventing the slide rail 502 from shaking during the working process. The two cooperate with each other, so as to ensure that during the process of pressing the FPC board by the upper mold 1 and the lower mold 2, the relative standard deviation value generated by the upper mold 1 and the lower mold 2 due to the shaking of the pressing fixture can be reduced.

[0026] Specifically, in this embodiment, a stabilizing rod 503 is slidably installed at one end of the mounting seat 5 close to the lower pressing plate 101, and the other end of the stabilizing rod 503 is fixedly connected to the pressure sensor 9 through an equal-height screw 8, and the connection is detachable. The pressure sensor 9 can be any sensor that can achieve this function in the prior art without limitation. Through the setting of the pressure sensor 24, the pressure at the pressure receiving point of the FPC board is tested, and the pressure is uniformly adjusted according to the pressure value to ensure that the pressure at each pressing point on the FPC board is uniform and reduce the rejection rate.

[0027] The working principle of the present utility model is as follows: When the mold is closed, the upper mold 1 drives the lower pressure plate 101 to press down through the downward pressing mechanism. The positioning plate 102 is fixedly connected to the external frame, so that the lower pressure plate 101 presses against the inner wall of the cavity 501 through the stabilizing rod 503, and then drives the mounting seat 5 to drive the upper mold pressing head 6 to move towards the lower mold pressing head 202. At the same time, through the cooperation of the slide rail 502 and the chute 701, the mounting seat 5 is slidably connected to the fixed slider 7, and the chute 701 plays a role in fixing the slide rail 502 to prevent the slide rail 502 from shaking during the working process, thereby ensuring that during the pressing process of the upper mold 1 and the lower mold 2 on the FPC board, the relative standard deviation value caused by the shaking of the pressing fixture between the upper mold 1 and the lower mold 2 can be reduced; at the same time, several groups of buffer fixators 4 are arranged around the upper mold pressing head 6 of the upper mold 1. The buffer fixator 4 is a device composed of a spring and a damping material that can buffer impact and vibration. In addition to being able to relieve impact and vibration, it can also ensure the overall stability of the upper mold 1 assembly; to reduce the relative standard deviation value caused by the shaking of the pressing fixture between the upper mold 1 and the lower mold 2.

[0028] The device is also provided with a pressure sensor 9. Through the setting of the pressure sensor 24, the pressure at the pressure receiving points of the FPC board is tested, and the pressure is uniformly adjusted according to the pressure value to ensure that the pressure at each pressing point on the FPC board is uniform and reduce the rejection rate.
