[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0016] The corrective fixture provided by this invention includes a fixture body with a positioning portion formed thereon for placing and positioning a flexible circuit board.

A first limiting member, a second limiting member, and a third limiting member are movably disposed on the fixture body. The first limiting member is located at one end of the electronic component and faces the upper and lower components of the electronic component. The second and third limiting members are both located at the other end of the electronic component, with the second limiting member facing the lower component and the third limiting member facing the upper component. The first limiting member can move toward the electronic component to a predetermined position. As the first limiting member moves, its upper end abuts against the upper component, and its lower end abuts against the lower component, pushing the electronic component to move and thus correcting it to the standard mounting position on the flexible circuit board. As the first limiting member moves toward the electronic component, the second limiting member also moves toward the electronic component to a predetermined position, creating a limiting space between the first and second limiting members that matches the lower component. This limits the lower component of the electronic component, ensuring it is mounted at the standard mounting position on the flexible circuit board. Similarly, the third limiting member moves toward the electronic component to a predetermined position, creating a limiting space between the first and third limiting members that matches the upper component. This limits the upper component of the electronic component, ensuring it is mounted at the standard position on the lower component.
[0017] Therefore, by limiting the flexible circuit board through the fixture body, and by using the first limiting member, the second limiting member and the third limiting member set on the fixture body to correct the mounting position of the lower and upper components on the flexible circuit board, the upper and lower components are corrected to the standard mounting position and limited at the standard mounting position. Thus, when the flexible circuit board is reflow soldered, the electronic components can be soldered to the standard position, ensuring the processing quality of the flexible circuit board and improving the product yield.

[0034] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.
[0035] The following reference Figures 1 to 7 The corrective fixture described in some embodiments of this application is described.
[0036] This application provides a corrective fixture, such as Figure 1 As shown, the fixture includes a main body with a positioning part formed thereon. The positioning part is used to place and limit the flexible circuit board. Electronic components are mounted on the flexible circuit board, including an upper component and a lower component mounted together. Preferably, the positioning part is a contoured groove adapted to the flexible circuit board.
[0037] Combination Figure 2 and Figure 5 As shown, a first limiting member 16, a second limiting member 17, and a third limiting member 22 are movably disposed on the main body of the fixture (the main body of the fixture includes a first fixture 1 and a second fixture 2, the first limiting member 16 and the second limiting member 17 are movably disposed on the first fixture 1, and the third limiting member 22 is movably disposed on the second fixture 2; the specific structure will be described below). The first limiting member 16 is located at one end of the electronic component, and the first limiting member 16 faces the upper and lower components of the electronic component; the second limiting member 17 and the third limiting member 22 are both located at the other end of the electronic component, and the second limiting member 17 faces the lower component of the electronic component, and the third limiting member 22 faces the upper component of the electronic component.
[0038] The first limiting member 16 can move toward the electronic component to a predetermined position. As the first limiting member 16 moves, the upper end of the first limiting member 16 can abut against the upper component, and the lower end of the first limiting member 16 can abut against the lower component, thus pushing the electronic component to move so as to correct the electronic component to the standard mounting position of the flexible circuit board through the first limiting member 16.
[0039] While the first limiting member 16 moves toward the electronic component, the second limiting member 17 can also move toward the electronic component to a predetermined position, so that a limiting space adapted to the lower component is formed between the first limiting member 16 and the second limiting member 17. Thus, the lower component of the electronic component is limited by the first limiting member 16 and the second limiting member 17, so that the lower component is mounted at the standard mounting position of the flexible circuit board.
[0040] The third limiting member 22 can also move toward the electronic component to a predetermined position, so that a limiting space adapted to the upper component is formed between the first limiting member 16 and the third limiting member 22, thereby limiting the upper component of the electronic component through the first limiting member 16 and the third limiting member 22, so that the upper component is mounted at the standard position of the lower component.
[0041] Therefore, by limiting the flexible circuit board through the fixture body, and by using the first limiting member 16, the second limiting member 17 and the third limiting member 22 set on the fixture body to correct the mounting position of the lower and upper components on the flexible circuit board, the upper and lower components are corrected to the standard mounting position and limited at the standard mounting position. Thus, when the flexible circuit board is reflow soldered, the electronic components can be soldered to the standard position, ensuring the processing quality of the flexible circuit board and improving the product yield.
[0042] Preferably, in the initial position, the first limiting member 16, the second limiting member 17, and the third limiting member 22 are all located away from the electronic component. When the electronic component is limited by the first limiting member 16, the second limiting member 17, and the third limiting member 22, the first limiting member 16 abuts against one end of the upper and lower components, and the distance between the second limiting member 17 and the lower component at the standard mounting position is 0.05mm, so that the lower component is limited between the first limiting member 16 and the second limiting member 17, and the lower component is prevented from being damaged due to clamping. The third limiting member 22 abuts against the other end of the upper component relative to the first limiting member 16, so as to clamp the upper component between the first limiting member 16 and the third limiting member 22, thereby realizing the correction and limitation of the upper component.
[0043] In one embodiment of this application, preferably, as shown below, Figures 1 to 4 As shown, the fixture body includes a first fixture 1, and a positioning part is located on the first fixture 1, so that the flexible circuit board can be placed on the first fixture 1 and the positioning part limits the flexible circuit board.
[0044] A first slider 11 and a second slider 12 are slidably connected to the first fixture 1. A first limiting member 16 is connected to the first slider 11, and a second limiting member 17 is connected to the second slider 12. The first slider 11 has a first station and a second station on the first fixture 1. The first slider 11 can be pushed so that it can slide back and forth between the first station and the second station, and drive the first limiting member 16 to move closer to or further away from the electronic component. Preferably, when the first slider 11 is located at the first station, the first limiting member 16 is located away from the electronic component; when the first slider 11 is located at the second station, the first limiting member 16 pushes the electronic component to the standard mounting position of the flexible circuit board, and the upper end of the first limiting member 16 abuts against the upper component, and the lower end of the first limiting member 16 abuts against the lower component.
[0045] The second slider 12 has a third station and a fourth station on the first fixture 1. The second slider 12 can be pushed so that it slides back and forth between the third station and the fourth station, and drives the second limiting member 17 to move closer to or further away from the electronic component. Preferably, when the second slider 12 is located at the third station, the first limiting member 16 is located away from the lower component; when the second slider 12 is located at the fourth station, a limiting space adapted to the lower component is formed between the second limiting member 17 and the first limiting member 16 at the second station, thereby correcting the lower component through the first limiting member 16 and the second limiting member 17, and limiting the lower component to the standard mounting position of the flexible circuit board.
[0046] Preferably, a first groove and a second groove are formed on the lower end surface of the first fixture 1. The first slider 11 is slidably connected in the first groove, and the second slider 12 is slidably connected in the second groove. The positioning part for placing the flexible circuit board is located on the upper end surface of the first fixture 1, and the positioning part includes a limiting slot 15 that penetrates through the upper and lower end surfaces of the first fixture 1. The portion of the flexible circuit board with electronic components is located in the limiting slot 15. The first limiting member 16 and the second limiting member 17 are both located in the limiting slot 15. The lower end of the first limiting member 16 passes through the limiting slot 15 through the first fixture 1 and is connected to the first slider 11. The lower end of the first limiting member 16 passes through the limiting slot 15 through the first fixture 1 and is connected to the second slider 12. Thus, the first limiting member 16 can be moved by the first slider 11, and the second limiting member 17 can be moved by the second slider 12.
[0047] Regarding how to achieve the movement of the first slider 11, in one embodiment of this application, preferably, a first elastic element is provided between one end of the first slider 11 and the first fixture 1; preferably, the first elastic element is located in the first groove, and one end of the first elastic element abuts against the first slider 11, while the other end of the first elastic element abuts against the side wall of the first groove. The first elastic element can provide an elastic driving force to the first slider 11, causing the first slider 11 to move from the second station to the first station, and then the first limiting member 16 is moved to a position away from the electronic component by the first slider 11.
[0048] In this embodiment, preferably, as follows: Figure 4 As shown, the first fixture 1 has a first guide hole 19 and the first slider 11 has a third guide hole 13. When the first slider 11 is in the first working position, the first guide hole 19 and the third guide hole 13 partially overlap. The axis of the first guide hole 19 passes through the third guide hole 13, and the axis of the first guide hole 19 is parallel to but not collinear with the axis of the third guide hole 13. Preferably, the fixture body further includes a second fixture 2, which can press against the first fixture 1. A first guide member 24 is provided at the position opposite to the first guide hole 19 on the second fixture 2. When the second fixture 2 presses against the first fixture 1, that is, when the first fixture 1 and the second fixture 2 are closed, the first guide member 24 can be inserted into the first guide hole 19 and then into the third guide hole 13. As the first guide member 24 is inserted into the third guide hole 13, the first guide member 24 will push the first slider 11 to overcome the elastic force of the first elastic member and move from the first station to the second station. Thus, the first slider 11 drives the first limiting member 16 to move toward the electronic component and pushes the electronic component to the standard mounting position of the flexible circuit board.
[0049] Similarly, regarding the movement of the second slider 12, a second elastic element is provided between the second slider 12 and the first fixture 1. The second elastic element can push the second slider 12 from the fourth station to the third station, and the second limiting member 17 stays at a position away from the electronic component. A fourth guide hole 14 is provided on the second slider 12, and a second guide hole 110 is provided on the first fixture 1 corresponding to the fourth guide hole 14. A second guide member 25 is provided on the second fixture 2. When the first fixture 1 and the second fixture 2 are closed, the second guide member 25 can be inserted into the second guide hole 110 and the fourth guide hole 14, and push the second slider 12 from the third station to the fourth station. Thus, the second slider 12 drives the second limiting member 17 to move towards the electronic component, so that the second limiting member 17 can cooperate with the first limiting member 16 to complete the correction and limiting of the lower component.
[0050] Preferably, the first guide member 24 includes a straight pipe section and a conical section located at the end of the straight pipe section. The conical section is conical, so that the end of the first guide member 24 can be smoothly inserted into the third guide hole 13 of the first slider 11. As the first guide member 24 is inserted, the sidewall of the conical section will press against the sidewall of the third guide hole 13, thereby pushing the first slider 11 to move until the straight pipe section enters the third guide hole 13. At this time, the first slider 11 slides to the second position.
[0051] Similarly, the structure of the second guide member 25 is the same as that of the first guide member 24, and will not be described again here.
[0052] In one embodiment of this application, preferably, as shown below, Figures 5 to 7 As shown, a third slider 21 is slidably connected to the end face of the second fixture 2 facing the first fixture 1. A third limiting member 22 is connected to the third slider 21, allowing the third slider 21 to move the third limiting member 22 so that the third limiting member 22 can move closer to or further away from the electronic component. The third slider 21 has a fifth station and a sixth station on the second fixture 2. The third slider 21 can be pushed so that it reciprocates between the fifth station and the sixth station. Preferably, when the third slider 21 is at the fifth station, the third limiting member 22 is located away from the electronic component; when the third slider 21 is at the sixth station, a limiting space adapted to the upper component is formed between the third limiting member 22 and the first limiting member 16 at the second station, thereby correcting the upper component through the first limiting member 16 and the third limiting member 22 and limiting the upper component to the standard mounting position of the flexible circuit board. Preferably, when the third slider 21 is located at the sixth station, the third limiting member 22 will abut against the upper component at the standard mounting position, so as to clamp the upper component by the first limiting member 16 and the third limiting member 22, and prevent the upper component from deviating from the standard mounting position during reflow soldering.
[0053] Regarding how to achieve the movement of the third slider 21, in one embodiment of this application, preferably, a third elastic member is provided between one end of the third slider 21 and the second fixture 2. The third elastic member can provide an elastic driving force to the third slider 21, so that the third slider 21 moves from the sixth station to the fifth station, and then drives the third limiting member 22 to move to a position away from the electronic components through the third slider 21.
[0054] Preferably, the second fixture 2 has a fifth guide hole and the third slider 21 has a sixth guide hole; when the third slider 21 is located at the fifth position, the fifth guide hole and the sixth guide hole partially overlap, the axis of the fifth guide hole passes through the sixth guide hole, and the axis of the fifth guide hole is parallel to but not collinear with the axis of the sixth guide hole.
[0055] A pressure plate 3 is also provided above the second fixture 2, and a fifth elastic member is provided between the pressure plate 3 and the second fixture 2. The fifth elastic member is arranged in a vertical direction, and its two ends abut against the second fixture 2 and the pressure plate 3 respectively, so that the pressure plate 3 is supported above the second fixture 2 by the fifth elastic member. When the pressure plate 3 is subjected to downward pressure, the pressure plate 3 can overcome the elastic force of the fifth elastic member and move downward toward the second fixture 2.
[0056] A third guide member 31 is provided on the end face of the pressure plate 3 facing the second fixture 2. The third guide member 31 is directly opposite the fifth guide hole, and the lower end of the third guide member 31 is located in the fifth guide hole. When the pressure plate 3 is pressed in the direction of the second fixture 2, the third guide member 31 will move downward and be inserted into the sixth guide hole of the third slider 21. As the third guide member 31 is inserted, the side wall of the third guide member 31 will squeeze the side wall of the sixth guide hole, so as to push the third slider 21 from the fifth station to the sixth station. Thus, the third slider 21 drives the third limiting member 22 to move in the direction of the electronic component, so that the third limiting member 22 cooperates with the first limiting member 16 to complete the limiting of the upper component.
[0057] In one embodiment of this application, preferably, as shown below, Figure 5 As shown, the third slider 21 includes a first sliding part 211 and a second sliding part 212. One end of the first sliding part 211 abuts against the third elastic member, and the other end of the first sliding part 211 is opposite to one end of the second sliding part 212. A fourth elastic member is disposed between the end of the second sliding part 212 away from the first sliding part 211 and the second fixture 2. The elastic force of the fourth elastic member is less than that of the third elastic member, so that the third slider 21 can move to the fifth station under the action of the third elastic member, and the second sliding part 212 abuts against the first sliding part 211 under the action of the fourth elastic member.
[0058] The third limiting member 22 is connected to the second sliding part 212, and the sixth guide hole is opened on the first sliding part 211. When it is necessary to limit the upper component by the third limiting member 22 in conjunction with the first limiting member 16, the pressure plate 3 is pressed down, so that the third guiding member 31 is inserted into the sixth guide hole. The third guiding member 31 will push the first sliding part 211 to move towards the sixth station. As the first sliding part 211 moves, the second sliding part 212 will move towards the first sliding part 211 to the sixth station under the action of the fourth elastic member. Thus, the second sliding part 212 drives the third limiting member 22 to move towards the electronic component, so that the third limiting member 22 abuts against the upper component at the standard mounting position, and then cooperates with the first limiting member 16 to complete the limiting of the upper component.
[0059] Preferably, the elastic force of the third elastic element is about 2N, and the elastic force of the fourth elastic element is about 1.5N, so that the third slider 21 can move from the sixth station to the fifth station under the action of the third elastic element; and when the third slider 21 moves from the fifth station to the sixth station, the second sliding part 212 is driven by the fourth elastic element with a smaller elastic force to move the third limiting member 22, which can reduce the pressure of the third limiting member 22 on the upper element, and the pressure of the third limiting member 22 on the upper element is buffered by the fourth elastic element, thereby avoiding damage to the upper element due to pressure.
[0060] In one embodiment of this application, preferably, as shown below, Figure 1 and Figure 5 As shown, the pressure plate 3 and the second fixture 2 are connected by a connector 4. The upper end of the connector 4 has a first stop 42, and the lower end of the connector 4 has a second stop 41. The pressure plate 3 has a first through hole, and the second fixture 2 has a second through hole 26 at a position opposite to the first through hole. The first through hole and the second through hole 26 are adapted to the second stop 41, so that the lower end of the connector 4 can pass through the pressure plate 3 and the second fixture 2 through the first through hole and the second through hole 26 respectively. Then, after rotating the connector 4 by a predetermined angle, the first stop 42 abuts against the upper end surface of the pressure plate 3, and the second stop 41 abuts against the lower end surface of the second fixture 2, thereby connecting the pressure plate 3 and the second fixture 2 together through the connector 4. Preferably, the fifth elastic element located between the pressure plate 3 and the second fixture 2 is sleeved on the connecting member 4. Through the elastic force of the fifth elastic element, the pressure plate 3 is moved away from the second fixture 2, and the pressure plate 3 abuts against the first stop part 42, while the second fixture 2 abuts against the second stop part 41. Pressing the connecting member 4 downward can provide downward pressure on the pressure plate 3 through the first stop part 42, causing the pressure plate 3 to overcome the pressure of the fifth elastic element and move downward toward the second fixture 2, thereby causing the third guide member 31 to be inserted into the third slider 21, so that the third slider 21 drives the third limiting member 22 to move.
[0061] Preferably, the second stop 41 is elongated, and the second through hole 26 is also elongated. When the second stop 41 is rotated to the same length direction as the second through hole 26, the second stop 41 can pass through the second through hole 26. When the second stop 41 is rotated to the same length direction as the second through hole 26, the second stop 41 will not be able to pass through the second through hole 26, and the second stop 41 will abut against the lower end face of the second fixture 2.
[0062] Preferably, the first fixture 1 has a third through hole 18, which is adapted to the second stop 41. Preferably, the third through hole 18 is also elongated. When the second fixture 2 is placed on the first fixture 1, the third through hole 18 is connected to the second through hole 26 and their length directions are the same. At this time, pressing down the connecting piece 4 allows the second stop 41 to pass through the third through hole 18 and pass through the first fixture 1. Then, rotating the connecting piece 4 to a predetermined angle causes the second stop 41 to abut against the lower end face of the first fixture 1, thereby placing the second fixture... 2. Fixed to the first fixture 1, the second fixture 2 and the first fixture 1 are closed. At this time, the first guide member 24 on the second fixture 2 will be inserted into the third guide hole 13 of the first slider 11, and the second guide member 25 will be inserted into the fourth guide hole 14 of the second slider 12, so as to drive the first slider 11 and the second slider 12 to move the corresponding first limiting member 16 and the second limiting member 17. The first limiting member 16 corrects the placement position of the electronic component, and cooperates with the second limiting member 17 to limit the lower component to the standard placement position. At the same time, as the connecting member 4 is pressed down, the pressure plate 3 will also drive the third guide member 31 to move downward, thereby driving the third limiting member 22 to move, so as to limit the upper component through the cooperation of the third limiting member 22 and the first limiting member 16.
[0063] In actual operation, the first fixture 1 and the second fixture 2 are initially separated, and the flexible circuit board can be placed in the positioning part of the first fixture 1. The first limiting member 16 and the second limiting member 17 are respectively located at the first and third workstations away from the electronic components. Then, the second fixture 2 is placed on the first fixture 1, and the connecting member 4 is pressed down to make the first fixture 1 and the second fixture 2 close together through the connecting member 4. The first guide member 24 and the second guide member 25 on the second fixture 2 will be inserted into the corresponding first slider 11 and second slider. Within 12, the corresponding first limiting member 16 and second limiting member 17 are pushed towards the electronic component. The first limiting member 16 pushes the electronic component to the standard mounting position, and the second limiting member 17 cooperates with the first limiting member 16 to complete the limiting of the lower component. The third guide member 31 on the pressure plate 3 will be inserted into the third slider 21 to push the third limiting member 22 towards the electronic component, so that the third limiting member 22 cooperates with the first limiting member 16 to complete the positioning of the upper component, thereby conveniently and quickly completing the correction and limiting of the mounting position of the electronic component.
[0064] In one embodiment of this application, preferably, as shown below, Figure 5As shown, a pressure-holding member 23 is also provided on the pressure plate 3 at the position corresponding to the electronic component. The end face of the pressure-holding member 23 facing the electronic component has a conforming pressure head adapted to the upper component. A fourth through hole is provided on the second fixture 2. When the pressure member moves downward, the pressure-holding member 23 can pass through the fourth through hole through the second fixture 2 and press on the upper end face of the upper component. Thus, the pressure-holding member 23 holds pressure on the upper component and the lower component, so that the upper component and the lower component are mounted in place.
[0065] Preferably, the upper end of the pressure holding member 23 is movably connected to the pressure plate 3, allowing the pressure holding member 23 to move up and down relative to the pressure plate 3. Preferably, the pressure plate 3 has a fifth through hole through which the pressure holding member 23 can pass. The upper end of the pressure holding member 23 has a third stop portion that abuts against the upper surface of the pressure plate 3. A sixth elastic member is fitted on the pressure holding member 23. The two ends of the sixth elastic member abut against the pressure plate 3 and the contouring pressure head, respectively. The sixth elastic member can provide a downward driving force to the pressure holding member 23, causing the third stop portion to abut against the pressure plate 3, and the contouring pressure head of the pressure holding member 23 to press against the upper component. At the same time, the movable pressure holding member 23 and the sixth elastic member provide a buffer to prevent the pressure of the pressure holding member 23 from being too high and damaging the electronic component.
[0066] In one embodiment of this application, preferably, a plurality of positioning portions are formed on the first fixture 1, and a flexible circuit board can be placed in each positioning portion; a plurality of first limiting members 16 are connected to the first slider 11, a plurality of second limiting members 17 are connected to the second slider 12, and a plurality of third limiting members 22 are connected to the third slider 21, and the plurality of first limiting members 16, the plurality of second limiting members 17, the plurality of third limiting members 22 and the plurality of flexible circuit boards correspond one-to-one; thereby, the correction fixture of this application can simultaneously correct and limit the mounting position of electronic components on multiple flexible circuit boards.
[0067] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
