Detailed Description
In order to make those skilled in the art better understand the technical solutions in the present specification, the technical solutions in the embodiments of the present specification will be clearly and completely described below with reference to the drawings in the embodiments of the present specification, and it is obvious that the described embodiments are only a part of the embodiments of the present specification, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present specification without making any creative effort shall fall within the protection scope of the present specification.
Referring to fig. 1, an embodiment of the present application provides a step positioning carrier, which includes a base 1; the positioning column 3 comprises a first column body 31, a second column body 32 and a connecting column 33, one end of the first column body 31 is fixedly connected to one side of the base 1, the other end of the first column body 31 is fixedly connected with one end of the connecting column 33, the other end of the connecting column 33 is fixedly connected with one end of the second column body 32, and the diameter of the first column body 31 is larger than that of the second column body 32; the carrier 2 is provided with a first positioning hole 21, and the inner wall of the first positioning hole 21 is in contact with the first column 31; the soft board 4, the soft board 4 is provided with a second positioning hole 41, and the inner wall of the second positioning hole 41 contacts with the first cylinder 31. One side of the base 1 is fixedly provided with a plurality of positioning columns 3. This positioning post 3 is a PIN in the actual operation of the person skilled in the art. The positioning post 3 includes three parts, namely a first column 31, a second column 32 and a connecting post 33. Let the diameter of the first cylinder 31 be D 1 The diameter of the connecting column 33 is D 2 The diameter of the second column 32 is D 3, The relationship between the diameters of the three parts is D 1 ＞D 2 ＞D 3 . The carrier 2 matched with the positioning column 3 is provided with a first positioning hole 21. The flexible board 4 is fixed on the carrier 2 through the second positioning hole 41.
As shown in fig. 2, it can be understood that in the present embodiment, the size relationship of the diameters of the first column 31, the second column 32 and the connecting column 33 is D 1 ＞D 2 ＞D 3 . In the production process, when the carrier 2 or the soft board 4 is installed and positioned, the first positioning hole 21 or the second positioning hole 41 which are close to each other can displace on the same plane, so that the length of the carrier 2 or the soft board 4 matched with the positioning column 3 is inconsistent, and the carrier 2 or the soft board 4 inclines. If the displacement is too large, the nesting and non-nesting of the adjacent first positioning hole 21 or second positioning hole 41 occur simultaneously, which may cause the carrier 2 or soft board 4 to deform seriously, resulting in local damage to the carrier 2 or soft board 4, and increaseThe cost of replacement and maintenance is increased, and the production efficiency is reduced. After the positioning posts 3 are designed to be stepped, the positioning accuracy of the carrier 2 or the flexible board 4 can be improved when the carrier or the flexible board is mounted or positioned, that is, when the adjacent first positioning hole 21 or the second positioning hole 41 is displaced, the carrier or the flexible board can be sleeved in the first positioning hole or the second positioning hole. When the carrier 2 or the soft board 4 is in cooperation with the second column 32 of the positioning column 3, displacement occurs, and after passing through the connecting column 33, the small displacement can be corrected, so that the carrier 2 or the soft board 4 can be well matched with the positioning column 3.
In one embodiment, the diameter of the first positioning hole 21 or the second positioning hole 41 is designed to be 2.00mm, the diameter of the positioning column 3 is designed to be 1.90mm, and the positioning precision is 0.1mm. After the positioning column 3 is designed to be stepped, the first column 31 of the positioning column 3 can be designed to be 1.95mm, and the positioning precision at this time is 0.05mm. The improvement of positioning accuracy can make carrier 2 more stable after fixed through the location, and the displacement that takes place because of the vibration is littleer at the in-process of processing, and the stability of soft board 4 has also obtained improving simultaneously for processing is more accurate, has reduced the rejection rate, has reduced manufacturing cost.
Further, the surface of the connecting column 33 is an arc surface. The surface of the connecting column 33 in the positioning column 3 is an arc-shaped surface, and the connecting column can be polished in the production process, so that the roughness and burrs on the surface of the connecting column 33 are reduced.
It can be understood that the connecting column 33 can correct the displacement error during the positioning of the carrier 2 or the flexible board 4, so that the carrier 2 or the flexible board 4 can be better fixed. The surface of the connecting column 33 is designed into an arc-shaped surface, so that violent collision can be avoided when the inner wall of the first positioning hole 21 or the second positioning hole 41 contacts the connecting column, and if burrs and raised parts appear on the surface of the connecting column 33, the carrier 2 and the soft plate 4 can be scratched, so that the carrier 2 and the soft plate 4 are partially damaged. Meanwhile, burrs and raised portions on the surface of the connecting column 33 reduce the positioning accuracy of the carrier 2 and the flexible board 4, thereby reducing the production efficiency. Meanwhile, the design of the arc-shaped surface of the connecting column 33 can well avoid stress concentration when the soft board 4 collides with the connecting column 33, and further the service life of the connecting column 33 can be prolonged. Specifically, the flexible board 4 collides with the surface of the connecting column 33 during the process of being engaged with the connecting column 33. If the surface of the connecting post 33 is rough, the surface of the connecting post 33 may be damaged due to stress concentration when the soft board 4 collides with the connecting post 33.
Further, one end of the second cylinder 32 is a circular arc surface. The positioning column 3 is fixedly arranged on one side of the base 1, and the specific structure is that one end of a first column 31 of the positioning column 3 is fixedly arranged on one side of the base 1. One end of the connecting column 33 is fixedly connected with the first column 31, and the other end of the connecting column 33 is connected with the second column 32.
It can be understood that, by designing one end of the second column 32 as an arc surface, when the carrier 2 and the flexible printed circuit board 4 are positioned, damage caused by collision between the second column 32 and the carrier 2 or the flexible printed circuit board 4 can be effectively reduced. In actual operation, there is an error in the fitting of the carrier 2 and the flexible board 4 with the second column 32. In this case, the carrier 2 or the flexible board 4 collides with one end of the second column 32. If one end of the second post 32 is a rough surface, the carrier 2 or the flexible board 4 may be damaged by impact. Meanwhile, due to the design of the arc surface, when the carrier 2 and the soft board 4 are positioned and have errors, the small errors can be corrected in an auxiliary mode, and the machining process is more stable.
According to the two embodiments, one end of the second column 32 of the positioning column 3 is an arc surface, and the surface of the connecting column 33 is also an arc surface. This makes carrier 2 and soft board 4 reduce a large amount of collision damages when the location to and can make first locating hole 21 and second locating hole 41 cooperate with reference column 3 better, very big improvement positioning accuracy, make its reliability in the process of production higher. After the FPC production is finished, the flexible board 4 needs to be separated from the side of the carrier 2. In an embodiment, the positioning column 3 is designed to be stepped, and in the separation process of the flexible printed circuit board 4, the flexible printed circuit board 4 can be better separated by the stepped positioning column 3, so that the processing efficiency of the FPC is greatly improved.
Furthermore, the joint of the connecting column 33 and the first column 31 and the joint of the connecting column 33 and the second column 32 are both provided with fillets. The part of the connecting column 33 connected with the first cylinder 31 is provided with a round angle, and the part of the connecting column 33 connected with the second cylinder 32 is also provided with a round angle.
It is understood that in actual production, when the carrier 2 and the flexible board 4 are positioned by a person skilled in the art, the carrier 2 or the flexible board 4 is very easy to collide during the process of just engaging with the connecting column 33 and disengaging from the connecting column 33. Both connections are rounded, which prevents the carrier 2 and the flexible sheet 4 from being damaged in the event of a collision between the two connections. Specifically, the connection between the inner wall of the first positioning hole 21 or the second positioning hole 41 and the connection column 33 and the first column 31 and the connection between the connection column 33 and the second column 32 collide. When the base 1 vibrates, such collision may cause damage to the inner walls of the first positioning hole 21 and the second positioning hole 41. Thereby increasing the rejection rate of FPC production and reducing the production efficiency of FPC.
Further, the flexible board 4 is connected to the carrier 2 through a magnetic sticker 22. As shown in fig. 3, a magnetic patch 22 is provided on the side of the flexible board 4 that contacts the carrier 2.
It can be understood that the flexible board 4 can contact with one side of the carrier 2 through the cooperation of the second positioning hole 41 and the positioning column 3. During production, the base 1 vibrates with great probability. When the base 1 vibrates, the carrier 2 also vibrates. The vibration of the carrier 2 causes the flexible board 4 and the carrier 2 to displace relative to each other. This greatly increases the rejection rate of the production. By arranging the magnetic paste 22, in the process that the second positioning hole 41 on the flexible board 4 is matched with the first column 31 of the positioning column 3, when the flexible board 4 contacts the carrier 2, the magnetic paste 22 can stably connect the flexible board 4 with the carrier 2. When the flexible printed circuit board 4 is stably connected with the carrier 2, the reliability of the carrier 2 in the production process can be effectively ensured, and meanwhile, the production precision of the flexible printed circuit board 4 is improved.
Further, the first positioning hole 21 and the second positioning hole 41 have the same diameter. The first positioning hole 21 is disposed on the carrier 2 for fixing the carrier 2 to the base 1. The second positioning hole 41 is disposed on the flexible board 4 for positioning the flexible board 4 to one side of the carrier 2 to connect with the carrier 2.
It can be understood that after the carrier 2 and the base 1 are positioned, the flexible board 4 is connected to one side of the carrier 2 through the cooperation of the second positioning hole 41 and the positioning post 3. Specifically, the positions of the first positioning holes 21 and the second positioning holes 41 correspond to each other one by one, and are matched with the positioning posts 3. In the production, the positions of the first positioning holes 21 and the second positioning holes 41 are set in a one-to-one correspondence relationship, so that the flexible board 4 can be processed well.
Further, the first positioning holes 21 and the second positioning holes 41 are arranged at equal intervals.
It can be understood that the first positioning hole 21 and the second positioning hole 41 are simultaneously matched with the positioning column 3. In the production process of the flexible board 4, a mass production continuous process is required. In one production line, a plurality of flexible boards 4 are fixed to one side of the carrier 2 for processing. Therefore, the first positioning holes 21 and the second positioning holes 41 correspond to the positioning posts 3 one by one, and the flexible board 4 is processed. The carrier 2 can be used for stably fixing and positioning the plurality of flexible boards 4.
