Description

Technical Field

[0001] The utility model relates to the technical field of flexible circuit boards, in particular to a multi-angle FPC pulling and fixing device. Background Art

[0002] Flexible circuit boards, also known as "soft boards", are printed circuits made of flexible insulating substrates. Flexible circuits provide excellent electrical properties, can meet the design needs of smaller and higher density installations, and also help reduce assembly processes and enhance reliability. Flexible circuit boards are the only solution to meet the miniaturization and mobility requirements of electronic products.

[0003] Currently, touch sensors mostly use FPC to lead out the circuit. If the adhesion between the FPC and the sensor is insufficient, the FPC may easily fall off, causing the touch sensor to be unusable. Therefore, the FPC adhesion needs to be tested after the touch sensor is connected to the FPC. In order to simulate various manual operations on the FPC during daily use, the FPC needs to be pulled out at various angles. However, conventional testing equipment can only meet the test of some angles, resulting in a relatively limited test angle, which cannot fully reflect the bonding condition of the FPC. Therefore, a multi-angle FPC pulling and fixing device is proposed. Utility Model Content

[0004] Based on this, it is necessary to provide a multi-angle FPC pulling and fixing device to address the above technical problems. A rotating axis is set on the bearing seat so that the clamping part can be rotated at any angle. At the same time, the clamping part can be fixed at the angle in conjunction with the limiting part, thereby meeting the pulling test of the FPC at different angles.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A multi-angle FPC pulling and fixing device, comprising:

[0007] A bearing seat, with side panels installed on both sides of the top of the bearing seat;

[0008] A rotating shaft, which is movably arranged on the side plate for the clamping member to be connected thereto;

[0009] Wherein, the clamping member is jointly arranged between the two rotating shafts for clamping and fixing the FPC;

[0010] A limiter, which is arranged on the side plate and is used to limit and fix the clamping angle of the clamping member on the rotating shaft to form a clamping test at different angles;

[0011] The limiting member comprises a support column fixed on the rotating shaft and a guide cylinder connected to the support column, wherein the limiting column is inserted into the guide cylinder.

[0012] Furthermore, the side plate has a plurality of limiting holes equidistantly distributed in the direction of the rotation trajectory of the limiting column.

[0013] Furthermore, one end of the limiting column extends outwardly of the guide cylinder to form a boss.

[0014] Furthermore, the four corners of the bearing seat are provided with through holes for fastening connection with external testing equipment.

[0015] Further, the clamping member includes two clamping plates and a bolt assembly that are relatively parallel and arranged;

[0016] The outer sides of the two clamping plates are respectively fixed to the corresponding rotating shafts.

[0017] Furthermore, a clamping space is formed on the inner sides of the two clamping plates for clamping and fixing the FPC.

[0018] Further, the bolt assembly includes a bolt body and a nut;

[0019] The bolt body passes through the two clamping plates and is connected with the nut on one side to lock the two clamping plates.

[0020] Furthermore, a lifting member is provided on the clamping plate, which is used to lift the FPC to be fixed so that it is placed in the middle of the clamping space.

[0021] Furthermore, the lifting member includes a supporting groove provided on the clamping plate for the support plate to move;

[0022] A support block is arranged on the outer side of the clamping plate and above the support plate. The support plate extends inside the support block and can slide along the length direction thereof.

[0023] Furthermore, a spring is connected between the support block and the support plate.

[0024] Compared with the prior art, the utility model has the following beneficial effects:

[0025] The multi-angle FPC pulling and fixing device provided by the utility model can adjust the pulling angle of the FPC bonded to the touch sensor by fixing the touch sensor to be tested in the clamping member and rotating the rotating shaft on the side plate. At the same time, with the setting of the limiter, the adjusted FPC can be positioned synchronously, which satisfies the angle adjustment under different test conditions, so that it can better reflect the bonding condition of the FPC.

[0026] By arranging the lifting piece on the clamping piece, when the FPC is fixed before testing, the support plate can temporarily lift the FPC inside the clamping plate, thereby eliminating the need to lift it manually, thus facilitating use by operators. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0049] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0050] Example 1

[0051] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a multi-angle FPC pulling and fixing device comprises a bearing seat 1, and side plates 11 are installed on both sides of the top of the bearing seat 1; a rotating shaft 12, which is movably inserted through the side plates 11 for connection of a clamping member 2 thereon, wherein the clamping member 2 is jointly arranged between the two rotating shafts 12 for clamping and fixing the FPC; a limiting member 3, which is arranged on the side plates 11 for limiting and fixing the clamping angle of the clamping member 2 on the rotating shaft 12 to form a clamping test at different angles, wherein the limiting member 3 comprises a supporting column 31 fixed on the rotating shaft 12 and a guide cylinder 32 connected to the supporting column 31, and a limiting column 33 is inserted in the guide cylinder 32.

[0052] The side plate 11 has a plurality of limit holes 34 equidistantly distributed in the direction of the rotation track of the limit column 33. The actual number of the limit holes 34 can be set according to the angle of the FPC to be tested. The limit column 33 is moved in the guide cylinder 32 so that one end of the limit column 33 is inserted into the corresponding limit hole 34 to form the positioning of the rotating shaft 12, and the clamping member 2 connected to the rotating shaft 12 is also limited at the same time.

[0053] At the same time, the limiting column 33 is slid outward to disengage one end of the limiting column 33 from the corresponding limiting hole 34. At this time, the rotating shaft 12 can drive the clamping member 2 thereon to adjust any pulling angle to meet the pulling test at different angles.

[0054] As a further optimization of this embodiment: one end of the limiting column 33 extends outside the guide cylinder 32 to form a boss 35, and the setting of the boss 35 facilitates the operator to insert and remove the limiting column 33 from the guide cylinder 32;

[0055] The four corners of the bearing seat 1 are provided with through holes 13 for fastening connection with external testing equipment. In actual application, the pulling and fixing device will be fixed to an external pulling test machine through the through holes 13 for fixed use.

[0056] The multi-angle FPC pulling and fixing device provided in the present embodiment is achieved by placing the touch sensor and the FPC bonded thereto between two clamping plates 21, and adjusting the bolt assembly 22 to fasten the touch sensor. After the touch sensor is fastened, the clamping plate 21 is rotated to rotate the FPC connected thereto to a suitable test angle, and then one end of the limiting column 33 in the limiting member 3 is inserted into the corresponding limiting hole 34 to fix the rotating shaft 12. After the angle of the FPC is fixed, one end of the FPC is connected to the test end of the outer pulling device, and a pulling test of the FPC is performed by lifting the pulling device. By replacing the clamping plate 21 at different angles, the FPC can be tested at multiple angles at different angles to obtain more comprehensive test results.

[0057] Example 2

[0058] The multi-angle FPC pulling and fixing device provided in Example 1 is further optimized. Specifically, Figure 4 and Figure 5 As shown, the clamping member 2 includes two relatively parallel clamping plates 21 and a bolt assembly 22, wherein the outer sides of the two clamping plates 21 are respectively fixed to the corresponding rotating shafts 12;

[0059] The inner sides of the two clamping plates 21 together form a clamping space for clamping and fixing the FPC, and the bolt assembly 22 includes a bolt body 220 and a nut 221;

[0060] The bolt body 220 passes through the two clamping plates 21 and is connected to a nut 221 on one side to lock the two clamping plates 21 .

[0061] Through the above-mentioned structural design, after the touch sensor is placed in the two clamping plates 21 in Example 1, the two clamping plates 21 are moved closer to each other by rotating the nut 221 or the bolt body 220 to shorten the relative distance between the two clamping plates 21, thereby fastening the touch sensor therein. At the same time, after the test is completed, the bolt assembly 22 can be disassembled by rotating the nut 221 or the bolt body 220 in the opposite direction, thereby removing the touch sensor and FPC clamped between the clamping plates 21.

[0062] Example 3

[0063] The multi-angle FPC pulling and fixing device provided in Example 1 or 2 is further optimized, such as Figure 4 and Figure 5 As shown, a lifting member 4 is provided on the clamping plate 21, which is used to lift the FPC to be fixed so that it is placed in the middle of the clamping space;

[0064] The lifting member 4 includes a support groove 42 provided on the clamping plate 21 for the support plate 41 to move;

[0065] A support block 43 is provided on the outer side of the clamping plate 21 and above the support plate 41. The support plate 41 extends inside the support block 43 and can slide along the length direction thereof.

[0066] In order to set the lifting member 4 without the need for the operator to manually lift the touch sensor when fixing it, after the lifting member 4 is set, the bottom ends of the touch sensor and FPC placed between the two clamping plates 21 will be supported by the two support plates 41 to form a temporary placement, without the need for additional lifting, and the operator only needs to tighten the bolt assembly 22;

[0067] In the process of fastening the touch sensor by the bolt assembly 22, since the two clamping plates 21 gradually approach each other, the support plate 41 thereon will slide relative to the clamping plates 21 without hindering the movement of the clamping plates 21 when sliding.

[0068] As a further optimization of this embodiment: a spring 44 is further connected between the support block 43 and the support plate 41. Through the setting of the spring 44, after the device completes the pull-out test on the connection between the touch sensor and the FPC, by removing the bolt assembly 22, the two clamping plates 21 are moved away from each other, and the corresponding support plate 41 thereon can slide and reset, and synchronously form support for the touch sensor and the FPC to prevent them from falling directly;

[0069] In the specific implementation process of this embodiment, since the touch sensor and the FPC are supported by the support plate 41 and will not fall down actively, the height of the touch sensor and the FPC can be adjusted on the support plate 41 before the touch sensor is fixed by the bolt assembly 22, so that the touch sensor and the FPC can be moved to the middle of the clamping plate 21 in a smaller volume state. Through this operation, the two fixed clamping plates 21 can better fix the touch sensor inside them, ensuring the stability of the touch sensor and the FPC during the pull-out test;

[0070] At the same time, if the touch sensor and FPC between the two clamping plates 21 are removed after the pull-out test through the bolt assembly 22, although the touch sensor and FPC have no direct contact with the support plate 41, the support plate 41 will be acted upon by the spring 44 to synchronously slide into place during the process of the two clamping plates 21 moving away from each other and separating, so that the touch sensor and FPC can be supported in time during the falling process to avoid their direct falling, which facilitates the subsequent collection and processing by the operator.

[0071] The use process of the multi-angle FPC pulling and fixing device provided by the utility model is as follows: the FPC with the touch sensor is placed between the two clamping plates 21, and the touch sensor and the FPC can be temporarily supported by the support plate 41. At this time, the touch sensor and the FPC can be adjusted in height on the surface of the support plate 41. If there is any adjustment, after the adjustment is completed, the bolt assembly 22 is rotated synchronously to make the two clamping plates 21 close to each other until the two clamping plates 21 complete the fixation of the touch sensor therein and stop, and then the rotating shaft 12 is rotated on the surface of the side plate 11, and the rotating shaft During the rotation of 12, the clamping plate 21, the touch sensor and the FPC thereon will be synchronously adjusted. When the angle of the FPC on the touch sensor is adjusted to a suitable position, the sliding limit post 33 is inserted into the corresponding limit hole 34 to complete the angle fixation of the FPC under the test state. Then, one end of the FPC is connected to the test end of the pulling test device. At this time, the pulling test of the FPC can be realized by starting the pulling test device. At the same time, by rotating the rotating shaft 12 at different angles, the pulling test of the FPC at different angles can be formed to obtain a more comprehensive pulling test result.
