The FPC circuit board is composed of copper foil, insulating base film, cover film, adhesive, etc.

[0003] The patent application with the application number CN201620243270.X discloses an FPC circuit board that is convenient for positioning, including a substrate. Copper foil layers are respectively provided in the middle parts of the two side surfaces of the substrate. A cover film is provided outside the copper foil layer. The substrate is provided with at least 3 linearly arranged positioning holes around the copper foil layer. The inner diameters of the positioning holes increase sequentially from left to right. By setting positioning holes of different sizes, it is convenient for the positioning of the FPC circuit board processing and the correctness of the placement direction, and drilling misalignment can be prevented.

[0004] However, this patent also has the following deficiencies. That is, before the FPC circuit board is positioned and installed on the surface of the substrate, it is necessary to first open a plurality of positioning holes on the surface of the FPC circuit board, then align the positioning holes on the surface of the FPC circuit board with the mounting holes on the surface of the substrate, and finally fix them with bolts. At present, when the positioning holes on the surface of the FPC circuit board are aligned with the mounting holes of the substrate, there may be deviations. When fixed with bolts, it will cause looseness at the connection between the circuit board and the substrate. In view of this situation, an FPC circuit board that is convenient for positioning is specifically proposed. Summary of the Invention

[0005] The purpose of the present invention is to provide an FPC circuit board that is convenient for positioning to solve the problems raised in the above background art.

A connection frame is fixedly connected to the top of the support feet. A circuit board is arranged inside the connection frame. Insertion slots are opened on both sides of the circuit board. Circuit components are fixedly connected to the top of the circuit board. Connection holes are opened on the surface of the circuit board. Insertion rings are fixedly connected to both sides of the inner wall of the circuit board. A double-sided sticker is fixedly connected to the bottom of the circuit board. The double-sided sticker is arranged on the surface of the connection hole. A displacement mechanism is arranged on the top of the connection frame. It also includes: The displacement mechanism includes a compression rod fixedly connected to the inner wall of the connecting frame. One end of the compression rod is fixedly connected to a connecting disc, and an expansion film is slidably connected to the inner wall of the connecting disc. One end of the expansion film away from the connecting disc is fixedly connected to a plug-in block, and one end of the plug-in block is fixedly plugged into the inner wall of the plug-in slot. A push handle is slidably connected in the slot hole at the end of the compression rod away from the plug-in block. A positioning component is arranged on the surface of the connecting disc. By pushing one end of the push handle towards the connecting frame, one end of the push handle slides and expands inside the compression rod.

[0007] According to the above technical solution, the positioning component includes a connecting arm. One end of the connecting arm is fixedly connected to the surface of the connecting disc. The end of the connecting arm away from the connecting disc is fixedly connected to a clamping plate. A connecting block is fixedly connected to the bottom of the clamping plate, and the connecting block is fixedly plugged into the inner wall of the plug-in ring. Align the surface groove of the circuit board with the surface of the clamping plate.

[0008] According to the above technical solution, a magnetic attraction ring is fixedly connected to the bottom of the connecting block. The connecting block is used to plug into the inner wall of the plug-in ring, and the connecting block is plugged into the inside of the plug-in ring.

[0009] According to the above technical solution, the displacement mechanism includes a rotating column. One end of the rotating column is rotatably connected to the top of the connecting frame through a rotating shaft. A moving arm is fixedly connected to the top of the rotating column. One end of the moving arm away from the rotating column is fixedly connected to a telescopic rod. The telescopic rod is arranged at the bottom of the moving arm. A sliding column is fixedly connected to the bottom of the telescopic rod. The sliding column is slidably connected to the inner wall of the connecting hole. A supporting component is arranged at the bottom of the sliding column. When the surface of the sliding column comes into contact with the connecting hole, the sliding column will be clamped on the surface of the connecting hole.

[0010] According to the above technical solution, the supporting component includes a plug-in rod. One end of the plug-in rod is plugged into the slot hole at the bottom of the sliding column. A supporting frame is fixedly connected to the end of the plug-in rod away from the sliding column. An expansion ring is fixedly connected to the surface of the supporting frame. A pushing component is arranged on the surface of the expansion ring. A compression film is slidably connected to the inner wall of the supporting frame. When the supporting frame comes into contact with the bottom of the inner wall of the substrate mounting hole.

[0011] According to the above technical solution, the pushing component includes a covering block. The covering block is fixedly connected to the surface of the expansion ring. A folding plate is fixedly connected to the surface of the covering block. A stretching rod is slidably connected to the inner wall of the covering block. A buffer pad is fixedly connected to the end of the folding plate away from the covering block.

[0012] According to the above technical solution, the compression film has a telescopic property. One end of the stretching rod extends into the interior of the expansion ring through the inner wall of the covering block. One end of the compression film is fixedly connected to one end of the stretching rod. When one end of the compression cover expands and contracts inside the support frame, it will drive one end of the compression film to expand and contract inward.

[0013] According to the above technical solution, one end of the push handle is slidably connected inside the compression rod. One end of the push handle is fixedly connected to the surface of the telescopic film through the interior of the compression rod. By squeezing the telescopic film with one end of the push handle, one end of the telescopic film is caused to push the plug-in block.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. By providing a positioning component in the present invention, since the clamping ring is arranged at a position below the circuit board groove, when the placement direction of the circuit board is incorrect, the insertion ring inside the circuit board groove cannot be slidably inserted into the connecting block on the surface of the clamping plate, thereby prompting the operator that the placement direction of the circuit board is incorrect and it cannot be fixedly connected to the mounting hole on the surface of the substrate.

[0015] 2. By providing a displacement mechanism in the present invention, when the circuit board slides downward to the surface of the substrate mounting hole, by stretching the push handle outward, the telescopic film is driven to expand and contract into the connecting disk, and the plug-in block can be separated from the interior of the circuit board, facilitating the installation of the circuit board on the substrate. By providing this mechanism, the connection hole on the surface of the circuit board and the substrate mounting hole can be easily positioned, improving the installation efficiency of the circuit board.

[0016] 3. By providing a support component in the present invention, when the folding plate drives the buffer pad to expand and contract outward to the inner wall of the substrate mounting hole, since the three folding plates on the inner wall of the expansion ring expand and contract outward simultaneously, when the three buffer pads come into contact with and squeeze the inner wall of the substrate mounting hole at the same time, the multiple buffer pads will expand and contract inward and generate a reverse thrust on one end of the stretching rod, which will drive the expansion ring to slide to the center of the substrate mounting hole under the action of the force. By providing this component, the connection hole on the surface of the circuit board and the center point of the substrate mounting hole can be quickly aligned.

[0017] 4. By providing a displacement mechanism in the present invention, and then by starting the telescopic device inside the moving arm, the telescopic rod is driven to expand and contract upward. When the sliding column moves upward, since the circuit board has been adsorbed and fixed on the surface of the substrate, the circuit board will be separated from the surface of the sliding column. By providing this mechanism, after accurately positioning the circuit board and the substrate, the circuit board and the substrate can be quickly installed, improving the subsequent installation efficiency of the circuit board.

Detailed implementation manners

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as a limitation to the present invention.

[0022] In the present invention, unless otherwise clearly defined and limited, terms such as "installation", "connection", "connection", "fixation", etc. should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] Embodiment 1: Refer to Figures 1 - 5 , the present invention provides a technical solution: an FPC circuit board convenient for positioning, including a support leg 1, a connection frame 2 is fixedly connected to the top of the support leg 1, a circuit board 10 is arranged on the inner wall of the connection frame 2, insertion slots 5 are opened on both sides of the circuit board 10, a circuit element 3 is fixedly connected to the top of the circuit board 10, connection holes 4 are opened on the surface of the circuit board 10, insertion rings 9 are fixedly connected to both sides of the inner wall of the circuit board 10, a double-sided sticker 6 is fixedly connected to the bottom of the circuit board 10, the double-sided sticker 6 is arranged on the surface of the connection hole 4, a displacement mechanism 8 is arranged on the top of the connection frame 2, and further includes: A displacement mechanism 7, including a compression rod 701 fixedly connected to the inner wall of the connection frame 2, a connection disk 703 is fixedly connected to one end of the compression rod 701, a telescopic film 704 is slidably connected to the inner wall of the connection disk 703, a plug-in block 705 is fixedly connected to one end of the telescopic film 704 away from the connection disk 703, one end of the plug-in block 705 is inserted and fixed to the inner wall of the insertion slot 5, a push handle 702 is slidably connected to the slot hole at one end of the compression rod 701 away from the plug-in block 705, a positioning component 706 is arranged on the surface of the connection disk 703, by pushing one end of the push handle 702 towards the connection frame 2, one end of the push handle 702 slides and expands in the compression rod 701, and the surface of the telescopic film 704 is extruded by one end of the push handle 702.

[0024] One end of the push handle 702 is slidably connected to the inside of the compression rod 701, one end of the push handle 702 is fixedly connected to the surface of the telescopic film 704 through the inside of the compression rod 701, so that one end of the telescopic film 704 pushes the plug-in block 705, driving one end of the plug-in block 705 to extend outwards and into the insertion slot 5 for insertion and fixation, thereby fixing the circuit board 10 on the surface of the connection disk 703. When it is necessary to move the connection hole 4 on the surface of the circuit board 10 to the mounting hole on the substrate surface, one end of the push handle 702 can be pressed.

[0025] The positioning component 706 includes a connecting arm 7061. One end of the connecting arm 7061 is fixedly connected to the surface of the connecting disk 703. A clamping plate 7063 is fixedly connected to the end of the connecting arm 7061 away from the connecting disk 703. A connecting block 7062 is fixedly connected to the bottom of the clamping plate 7063. The connecting block 7062 is inserted and fixed to the inner wall of the insertion ring 9. One end of the telescopic film 704 will expand and contract outward to push the clamping plate 7063. By pushing the clamping plate 7063, the circuit board 10 on the surface of the clamping plate 7063 is driven to move up and down inside the connecting frame 2, thereby driving the connection holes 4 on the surface of the circuit board 10 close to the mounting holes on the surface of the substrate. When the circuit board 10 slides down to the surface of the substrate mounting hole, by stretching and pushing the pushing rod 702 outward, the telescopic film 704 is driven to expand and contract into the connecting disk 703, and the insertion block 705 can be separated from the inside of the circuit board 10, which is convenient for the installation of the circuit board 10 and the substrate. The connection holes 4 on the surface of the circuit board 10 and the substrate mounting holes can be easily positioned, improving the installation efficiency of the circuit board 10.

[0026] A magnetic suction ring is fixedly connected to the bottom of the connecting block 7062. The connecting block 7062 is used to insert into the inner wall of the insertion ring 9. First, place the support feet 1 on the surface of the substrate, then place the circuit board 10 inside the connecting frame 2, and align the surface groove of the circuit board 10 with the surface of the clamping plate 7063. When the surface groove of the circuit board 10 approaches the surface of the clamping plate 7063, a magnetic suction effect will be generated between the magnetic suction rings at the tops of the multiple connecting blocks 7062 on the surface of the clamping plate 7063 and the insertion rings 9 in the grooves of the circuit board 10. Thus, the connecting block 7062 is adsorbed into the inside through the multiple insertion rings 9. By inserting the connecting block 7062 into the inside of the insertion ring 9, the circuit board 10 is fixed on the surface of the clamping plate 7063. Since the clamping ring is arranged at the lower position of the groove of the circuit board 10, when the placement direction of the circuit board 10 is incorrect, the insertion rings 9 inside the groove of the circuit board 10 cannot be slidably inserted into the connecting blocks 7062 on the surface of the clamping plate 7063, thus prompting the operator that the placement direction of the circuit board 10 is incorrect and it cannot be fixedly connected to the substrate surface mounting hole.

[0027] Embodiment 2: On the basis of Embodiment 1, continue to refer to Figures 6 - 7, the present invention provides a technical solution: The shifting mechanism 8 includes a rotating column 801. One end of the rotating column 801 is rotatably connected to the top of the connecting frame 2 through a rotating shaft. A moving arm 802 is fixedly connected to the top of the rotating column 801. One end of the moving arm 802 away from the rotating column 801 is fixedly connected to a telescopic rod 803. The telescopic rod 803 is arranged at the bottom of the moving arm 802. The bottom of the telescopic rod 803 is fixedly connected to a sliding column 804. The sliding column 804 is slidably connected to the inner wall of the connecting hole 4. A support assembly 805 is arranged at the bottom of the sliding column 804. When the connecting hole 4 on the surface of the circuit board 10 moves to the bottom of the sliding column 804, by starting the telescopic device inside the shifting arm, the telescopic column is driven to expand and contract downward and drive the sliding column 804 to move downward. When the surface of the sliding column 804 comes into contact with the connecting hole 4, the sliding column 804 will be clamped on the surface of the connecting hole 4.

[0028] The support assembly 805 includes an insertion rod 8053. One end of the insertion rod 8053 is inserted into the bottom slot of the sliding column 804. A support frame 8052 is fixedly connected to the end of the insertion rod 8053 away from the sliding column 804. An expansion ring 8051 is fixedly connected to the surface of the support frame 8052. A pushing assembly 806 is arranged on the surface of the expansion ring 8051. A compression film 8054 is slidably connected to the inner wall of the support frame 8052. When the sliding column 804 moves downward and drives the expansion ring 8051 into the installation hole on the surface of the substrate, when the support frame 8052 comes into contact with the inner wall bottom of the substrate installation hole, since a compression cover is slidably connected to the inner side of the support frame 8052 away from the insertion rod 8053, the compression cover inside the support frame 8052 will be pushed by the inside of the substrate installation hole, so that the compression cover retracts inward into the support frame 8052. One end of the compression cover is fixedly connected to one end of the compression film 8054 through the inner wall of the support frame 8052. When one end of the compression cover retracts and extends inside the support frame 8052, it will drive one end of the compression film 8054 to retract and extend inward and slide and retract into the expansion ring 8051.

[0029] The compression film 8054 has telescopic properties. One end of the stretching rod 8062 extends into the interior of the expansion ring 8051 through the inner wall of the covering block 8061. One end of the compression film 8054 is fixedly connected to one end of the stretching rod 8062. After the expansion ring 8051 is fixed inside the substrate mounting hole, by activating the telescopic device inside the moving arm 802, the telescopic rod 803 is driven to continue telescoping downward, which causes the expansion ring 8051 at the bottom of the sliding column 804 to be stressed and generate pressure on the bottom of the sliding column 804. Since the sliding column 804 is connected by a plurality of slidable and telescopic sleeves, when the bottom of the sliding column 804 is stressed, it will telescope inward. When the sliding column 804 is completely contracted inward, this will bring the circuit board 10 on the surface of the sliding column 804 closer to the surface of the mounting hole. And a double-sided tape 6 is mounted on the surface of the connection hole 4 of the circuit board 10. The connection hole 4 of the circuit board 10 is aligned and adsorbed with the substrate mounting hole through the double-sided tape 6, so that the connection hole 4 of the circuit board 10 and the substrate mounting hole do not shift. Then, by activating the telescopic device inside the moving arm 802, the telescopic rod 803 is driven to telescope upward. When the sliding column 804 moves upward, since the circuit board 10 has been adsorbed and fixed on the substrate surface, this will cause the circuit board 10 to separate from the surface of the sliding column 804. After the circuit board 10 and the substrate are accurately positioned, the circuit board 10 and the substrate can be quickly installed, improving the subsequent installation efficiency of the circuit board 10.

[0030] Embodiment 3: On the basis of Embodiment 2, continue to refer to Figure 8 The present invention provides a technical solution: The pushing assembly 806 includes a covering block 8061. The covering block 8061 is fixedly connected to the surface of the expansion ring 8051. A folding plate 8063 is fixedly connected to the surface of the covering block 8061. A stretching rod 8062 is slidably connected to the inner wall of the covering block 8061. One end of the folding plate 8063 away from the covering block 8061 is fixedly connected to a buffer pad 8064. One end of the stretching rod 8062 away from the covering block 8061 is fixedly connected to the surface of the folding plate 8063. One end of the compression film 8054 will press on the stretching rod 8062, thereby driving one end of the stretching rod 8062 to telescope outward from the inside of the covering block 8061. By pushing the folding plate 8063 with one end of the stretching rod 8062, this will drive the folding plate 8063 to telescope outward. When the folding plate 8063 drives the buffer pad 8064 to telescope outward to the inner wall of the substrate mounting hole, since the three folding plates 8063 on the inner wall of the expansion ring 8051 telescope outward simultaneously, when the three buffer pads 8064 come into contact with and squeeze the inner wall of the substrate mounting hole at the same time, the plurality of buffer pads 8064 will telescope inward and generate a reverse thrust on one end of the stretching rod 8062, which will drive the expansion ring 8051 to slide to the center of the substrate mounting hole under the action of the force, and the connection hole 4 on the surface of the circuit board 10 can be quickly aligned with the center point of the substrate mounting hole.
