Description

Technical Field

[0001] This utility model relates to the field of flexible circuit board defect detection technology, and in particular to a feeding device for flexible circuit board defect detection. Background Technology

[0002] Since its development in the 1950s, flexible circuit boards (PCBs) have been widely used in various fields such as consumer electronics, new energy vehicles, and medical devices due to their advantages of flexibility, high integration, and lightweight design. However, the manufacturing process of flexible circuit boards is relatively complex and may result in various defects, thus necessitating defect detection.

[0003] Currently, when loading flexible circuit boards for defect detection, clamping or pressing is used to fix the flexible circuit boards. However, this method is prone to causing indentations or even damage to the flexible circuit boards due to excessive clamping or pressing force. Utility Model Content

[0004] The purpose of this invention is to avoid indentations or damage to the flexible circuit board during the loading and fixing process.

[0005] To achieve the above objectives, this utility model provides a feeding device for defect detection of flexible circuit boards, comprising: a feeding platform, a support, and an adsorption device;

[0006] The loading platform is used to place flexible circuit boards;

[0007] The support is located on one side of the loading platform, and the adsorption device is installed on the support. The adsorption device is used to adsorb the flexible circuit board on the loading platform.

[0008] The adsorption device includes an adsorption lifting mechanism;

[0009] The adsorption lifting mechanism is mounted on the bracket and is connected to a suction cup.

[0010] Preferably, it further includes: a horizontal sliding rail, which is mounted on the bracket;

[0011] The adsorption device is mounted on the horizontal sliding rail and moves along the horizontal sliding rail.

[0012] Preferably, the adsorption device further includes a movable mounting plate, which is mounted on the horizontal sliding rail and moves along the horizontal sliding rail, and the adsorption lifting mechanism is connected to the movable mounting plate.

[0013] Preferably, the suction cup is a vacuum sponge suction cup.

[0014] Preferably, the adsorption lifting mechanism is a cylinder-driven mechanism.

[0015] Preferably, it also includes protective paper;

[0016] The protective paper is placed on the loading platform and is used to place the flexible circuit board.

[0017] Preferably, the loading platform includes a loading platform plate and a loading lifting mechanism;

[0018] The loading platform is mounted on the loading lifting mechanism, and the loading platform is used to place flexible circuit boards.

[0019] Preferably, the loading platform further includes a loading base plate;

[0020] The feeding lifting mechanism is installed on the feeding base plate, and a telescopic rod connects the feeding base plate and the feeding platform.

[0021] Compared with the prior art, the present invention discloses a loading device for defect detection of flexible circuit boards. Its advantages are as follows: The flexible circuit board is placed on a loading platform, a support is installed on one side of the loading platform, and a suction lifting mechanism is installed on the support. The suction lifting mechanism drives a connected suction cup to descend and adsorb the flexible circuit board on the loading platform.

[0025] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0026] In the description of this utility model, it should be understood that the terms "installation," "connection," and "linking" used in this utility model 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. For those skilled in the art, the specific meaning of the above terms in the embodiments of this utility model can be understood according to the specific circumstances.

[0027] like Figure 1 As shown, an embodiment of the present invention provides a feeding device for detecting defects in flexible circuit boards, comprising: a feeding platform 2, a support 1, and an adsorption device 3; the feeding platform 2 is used to place flexible circuit boards 6; the support 1 is disposed on one side of the feeding platform 2, and the adsorption device 3 is mounted on the support 1, and the adsorption device 3 is used to adsorb the flexible circuit boards 6 on the feeding platform 2; the adsorption device 3 includes an adsorption lifting mechanism 31; the adsorption lifting mechanism 31 is mounted on the support 1, and the adsorption lifting mechanism 31 is connected to a suction cup 33.

[0028] It should be noted that the flexible circuit board 6 is placed on the loading platform 2, the bracket 1 is located on one side of the loading platform 2, and the adsorption lifting mechanism 31 is installed on the bracket 1. The adsorption lifting mechanism 31 drives the connected suction cup 33 to descend and adsorb the flexible circuit board 6 located on the loading platform 2. After adsorption, the adsorption lifting mechanism 31 drives the connected suction cup 33 and the flexible circuit board 6 to rise, so that the flexible circuit board 6 leaves the loading platform 2. The adsorption device 3 installed on the bracket 1 in this application fixes the flexible circuit board 6 on the loading platform 2 by adsorption. Compared with the clamping or pressing fixing method in the prior art, the fixing method of the flexible circuit board 6 in this application is more gentle, which can avoid indentation or damage to the flexible circuit board 6 when loading it, and at the same time ensure that it presents a better flatness during subsequent inspection, thereby improving the accuracy of defect detection.

[0029] See Figure 1 In a more specific embodiment, it further includes: a horizontal moving slide rail 4, which is mounted on the bracket 1; and an adsorption device 3, which is mounted on the horizontal moving slide rail 4 and moves along the horizontal moving slide rail 4.

[0030] It should be noted that the adsorption device 3 is installed on the horizontal moving slide rail 4 and moves along the horizontal moving slide rail 4, so that after the adsorption device 3 adsorbs the flexible circuit board 6, it can move to the next process.

[0031] See Figure 1In a more specific embodiment, the adsorption device 3 further includes a movable mounting plate 32, which is mounted on and moves along the horizontal sliding rail 4, and the adsorption lifting mechanism 31 is connected to the movable mounting plate 32.

[0032] It should be noted that the movable mounting plate 32 of the adsorption device 3 is mounted on the horizontal moving slide rail 4 and moves along the horizontal moving slide rail 4. When disassembling the adsorption device 3, the movable mounting plate 32 is detached from the horizontal moving slide rail 4. The movement of the movable mounting plate 32 along the horizontal moving slide rail 4 is driven by a servo motor.

[0033] The horizontal sliding rail 4 is specifically a horizontal sliding module, including a module slide rail and a slider mounted on the module slide rail. The movable mounting plate 32 is mounted on the slider so that it can move along the module slide rail.

[0034] See Figure 1 In a more specific embodiment, suction cup 33 is a vacuum sponge suction cup.

[0035] It should be noted that the suction cup 33 is a vacuum sponge suction cup. The vacuum sponge suction cup adsorbs the flexible circuit board 6 more gently, which can effectively avoid damaging the flexible circuit board 6 and ensure that the flexible circuit board 6 has a good flatness.

[0036] See Figure 1 In a more specific embodiment, the adsorption lifting mechanism 31 is a cylinder-driven mechanism.

[0037] It should be noted that the cylinder drive mechanism is energy-saving and does not require an external power supply. It is less prone to circuit failures and has a long service life.

[0038] The adsorption lifting mechanism 31 can also be other existing lifting structures.

[0039] See Figure 1 In a more specific embodiment, a protective paper 5 is also included; the protective paper 5 is disposed on the loading platform 2 and is used to place the flexible circuit board 6.

[0040] It should be noted that the protective paper 5 is placed on the loading table 2. The protective paper 5 is used to place the flexible circuit board 6, so that the protective paper 5 is sandwiched between the loading table 21 and the flexible circuit board 6.

[0041] The protective paper 5 can prevent the flexible circuit board 6 from directly contacting the loading table 2, thus protecting the flexible circuit board 6.

[0042] See Figure 1-2 In a more specific embodiment, the loading platform 2 includes a loading platform plate 21 and a loading lifting mechanism 22; the loading platform plate 21 is mounted on the loading lifting mechanism 22 and is used to place the flexible circuit board 6.

[0043] It should be noted that, in the initial state, the loading lifting mechanism 22 rises, raising the loading platform 21 to its highest point, and the flexible circuit board 6 is placed on the loading platform 21. The suction lifting mechanism 31 of the suction device 3 drives the connected suction cup 33 to descend until the suction cup 33 picks up the flexible circuit board 6 on the loading platform 21, after which the suction cup 33 rises again. At the same time that the suction cup 33 picks up the flexible circuit board 6, the loading lifting mechanism 22 drives the connected loading platform 21 to descend, ensuring that the flexible circuit board 6 is detached from the loading platform 21.

[0044] The loading lifting mechanism 22 is driven by a servo motor. The structure of the loading lifting mechanism 22 may include a rotating shaft, a swing arm, and a transmission rod. One end of the rotating shaft is connected to the servo motor, and the other end is connected to one end of the swing arm. The other end of the swing arm is connected to the loading platform 21 through the transmission rod. Thus, the servo motor drives the rotating shaft to rotate, the rotating shaft drives the swing arm to swing, and the swing arm drives the loading platform 21 to move up and down through the transmission rod. Alternatively, the loading lifting mechanism 22 may also be a cylinder, which drives the loading platform 21 to move up and down. The loading lifting mechanism 22 may also be other existing lifting structures.

[0045] See Figure 1-2 In a more specific embodiment, the loading platform 2 further includes a loading base plate 23; a loading lifting mechanism 22 is installed on the loading base plate 23, and a telescopic rod 24 is connected between the loading base plate 23 and the loading platform 21.

[0046] It should be noted that a telescopic rod 24 is connected between the loading base plate 23 and the loading platform 21. When the loading lifting mechanism 22 lifts the loading platform 21, the telescopic rod 24 extends; when the loading lifting mechanism 22 drives the loading platform 21 to descend, the telescopic rod 24 shortens. The telescopic rod 24 ensures the stability of the position between the loading platform 21 and the loading base plate 23.

[0047] The working process of this utility model is as follows: the flexible circuit board 6 is placed on the loading platform 2, the support 1 is set on one side of the loading platform 2, and the adsorption lifting mechanism 31 is installed on the support 1. The adsorption lifting mechanism 31 drives the connected suction cup 33 to descend and adsorb the flexible circuit board 6 located on the loading platform 2. After adsorption, the adsorption lifting mechanism 31 drives the connected suction cup 33 and the flexible circuit board 6 to rise, so that the flexible circuit board 6 leaves the loading platform 2.

[0048] In summary, this utility model provides a loading device for detecting defects in flexible circuit boards. The method of fixing the flexible circuit board 6 is gentler than the clamping or pressing method in the prior art. It can avoid indentation or damage to the flexible circuit board 6 during loading, and at the same time ensure that it presents a better flatness during subsequent inspection, thereby improving the accuracy of defect detection.

[0049] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
