[0002] With the trend of miniaturization and high performance in electronic devices, flexible circuit boards have been widely used in various electronic products, such as smartphones, wearable devices, and tablets, due to their bendability and thinness.

[0003] However, because the flexible substrate of the flexible circuit board is easy to bend, the traditional feeding mechanism needs to change rollers of different diameters to match the track width when switching between different specifications of flexible substrates. This not only relies on skilled technical workers to operate, but also poses a risk of installation errors, which is labor-intensive, time-consuming to adjust, and affects production efficiency. Moreover, the traditional feeding mechanism is difficult to guarantee the conveying accuracy, which leads to defects in the final product. Utility Model Content

[0015] The beneficial effects are:

[0016] This application discloses a feeding mechanism and feeding system. A first driving component includes a first lead screw, which is rotatably mounted on a frame around its own axis. The first lead screw is driven by a clamping component. The two clamping mechanisms of the clamping component can clamp both sides of the workpiece. The thread of the first lead screw converts its rotation into the forward and backward movement of the clamping component along a first direction, thereby driving the entire workpiece to move forward and backward along the first direction, achieving conveying. The transmission accuracy of the first lead screw is higher than that of rollers in the prior art. Using the first lead screw during continuous feeding avoids cumulative errors, resulting in higher conveying accuracy. A second driving component is mounted on the frame and is driven by two clamping mechanisms. This drives the two clamping mechanisms to move closer or further apart along a second direction, allowing for rapid adjustment of the workpiece width that the two clamping mechanisms can hold. This enables the feeding mechanism to adapt to flexible substrates of different specifications without the need to replace rollers of different diameters, reducing reliance on manual labor, simplifying installation, reducing errors, effectively lowering debugging time costs, and increasing production efficiency.

[0033] A first aspect of this application provides a feeding mechanism for conveying a workpiece 900 along a first direction X. The workpiece 900 may be a flexible substrate.

[0034] See Figures 1 to 6 As shown, the feeding mechanism includes: a frame 100, a first drive assembly 300, a clamping assembly 200, and a second drive assembly 400;

[0035] The first drive assembly 300 includes a first lead screw 310, which is rotatably mounted on the frame 100 about its own axis.

[0036] The clamping assembly 200 includes two clamping mechanisms 210 spaced apart along the second direction Y, which are used to clamp the two sides of the workpiece 900 respectively; the first lead screw 310 is configured to drive the clamping assembly 200 to move back and forth along the first direction X.

[0037] The second drive assembly 400 is connected to the clamping assembly 200 to drive the two clamping mechanisms 210 to move closer or further apart along the second direction Y; wherein the first direction X is perpendicular to the second direction Y.

[0038] In this embodiment, the first drive assembly 300 includes a first lead screw 310, which is rotatably mounted on the frame 100 around its own axis. The first lead screw 310 is driven by the clamping assembly 200. The two clamping mechanisms 210 of the clamping assembly 200 can clamp the two sides of the workpiece 900. The thread of the first lead screw 310 converts its own rotation into the movement of the clamping assembly 200 back and forth along the first direction X, and drives the workpiece 900 as a whole to move back and forth along the first direction X, thereby realizing the conveying. The transmission accuracy of the first lead screw 310 is higher than that of the roller in the prior art. The use of the first lead screw 310 can avoid the accumulation of errors in the continuous feeding process, so that the feeding mechanism has higher conveying accuracy.

[0039] The second drive assembly 400 is mounted on the frame 100. The second drive assembly 400 is connected to two clamping mechanisms 210 respectively to drive the two clamping mechanisms 210 to move closer or further away from each other along the second direction Y. In this way, the width of the workpiece 900 that the two clamping mechanisms 210 can clamp can be quickly adjusted, thereby enabling the feeding mechanism to adapt to flexible substrates of different specifications without the need to change rollers of different diameters. This reduces the dependence on manpower, simplifies installation, reduces errors, effectively reduces debugging time costs, and makes production efficiency higher.

[0040] In some possible embodiments, see Figures 1 to 6 As shown, the first drive assembly 300 also includes a first nut seat 320; a first lead screw 310 extends along a first direction X; the first nut seat 320 is screwed into the first lead screw 310 to move back and forth along the first direction X; and the clamping assembly 200 is connected to the first nut seat 320.

[0041] The first lead screw 310 extends along the first direction X and is rotatably mounted on the frame 100 around its own axis. The clamping assembly 200 is connected to the first nut seat 320. When the first lead screw 310 rotates around its own axis, the first nut seat 320, which cooperates with the first lead screw 310, converts the rotation into a back-and-forth movement along the first direction X. This allows the clamping assembly 200 to move back and forth along the first direction X as a whole. The two clamping mechanisms 210 of the clamping assembly 200 can clamp the two sides of the workpiece 900 and drive the workpiece 900 to move back and forth along the first direction X as a whole, thus realizing the conveying. The transmission accuracy of the threaded engagement between the first lead screw 310 and the first nut seat 320 is higher than that of the roller in the prior art. In this way, the feeding mechanism can avoid the accumulation of errors during continuous feeding, resulting in higher conveying accuracy.

[0042] In some possible embodiments, see Figures 1 to 6 As shown, the first drive assembly 300 also includes two bearing seats 330 and a first drive member 340; the two bearing seats 330 are spaced apart on the frame 100 along the first direction X, and the two ends of the first lead screw 310 are respectively mounted on the two bearing seats 330; the first drive member 340 is connected to the first lead screw 310 in a transmission connection.

[0043] Thus, the two bearing seats 330 are spaced apart on the frame 100 along the first direction X, and the two ends of the first lead screw 310 are respectively mounted on the two bearing seats 330, so that the first lead screw 310 can rotate around its own axis.

[0044] In practice, the first driving member 340 is connected to the first lead screw 310. When the first driving member 340 drives the first lead screw 310 to rotate clockwise around its own axis, the first nut seat 320 that cooperates with the first lead screw 310 converts the clockwise rotation into forward movement along the first direction X. This allows the clamping assembly 200 to move forward along the first direction X as a whole. The two clamping mechanisms 210 of the clamping assembly 200 can clamp the two sides of the workpiece 900 and drive the workpiece 900 to move forward along the first direction X as a whole, thus realizing the conveying.

[0045] Similarly, when the first driving component 340 drives the first lead screw 310 to rotate counterclockwise around its own axis, it can drive the workpiece 900 to move backward along the first direction X, thereby realizing the conveying; this will not be elaborated here.

[0046] Optionally, the first driving component 340 can be a stepper motor. The first driving component 340 is connected to the first lead screw 310. The transmission accuracy of the first lead screw 310 and the first nut seat 320 through thread engagement is higher than that of the roller in the prior art. In this way, the feeding mechanism can avoid the generation of cumulative errors during continuous feeding, resulting in higher conveying accuracy.

[0047] In some possible embodiments, see Figures 1 to 6 As shown, the clamping assembly 200 also includes a first slide rail 220; the first slide rail 220 extends along the second direction Y and is fixedly connected to the first nut seat 320; two clamping mechanisms 210 are slidably disposed on the first slide rail 220.

[0048] Thus, the first slide rail 220 and the first nut seat 320 remain fixed, and the two clamping mechanisms 210 are limitedly connected to the first slide rail 220 in the first direction X. When the second drive assembly 400 drives the two clamping mechanisms 210 to move closer or further away from each other in the second direction Y, by sliding the two clamping mechanisms 210 on the first slide rail 220, interference between the movement of the clamping mechanisms 210 in the second direction Y and the first nut seat 320 can be effectively prevented.

[0049] When the first driving member 340 drives the first lead screw 310 to rotate around its own axis, the first nut seat 320, which cooperates with the first lead screw 310, converts the rotation into forward and backward movement along the first direction X. In turn, the clamping mechanism 210 can be driven to move forward and backward along the first direction X through the first slide rail 220. The two clamping mechanisms 210 of the clamping assembly 200 can clamp the two sides of the workpiece 900 and drive the workpiece 900 as a whole to move forward and backward along the first direction X, so as to realize the conveying.

[0050] In some possible embodiments, see Figures 1 to 6 As shown, each clamping mechanism 210 includes a mounting base 211, two grippers 212, a second slide rail 214, and a base plate 215.

[0051] Two grippers 212 are vertically arranged on the mounting base 211 along the third direction Z, and the two grippers 212 can move closer or further apart along the third direction Z. A base plate 215 is movably mounted on the frame 100 along the second direction Y; a second slide rail 214 extends along the first direction X and is mounted on the base plate 215; the mounting base 211 is slidably mounted on the second slide rail 214. The first direction X, the second direction Y, and the third direction Z are arranged perpendicularly to each other.

[0052] By setting the two grippers 212 of the clamping mechanism 210 to move closer to each other along the third direction Z, the workpiece 900 is positioned along the second direction Y. This allows the two clamping mechanisms 210 of the clamping assembly 200 to clamp the two sides of the workpiece 900 respectively. When the first lead screw 310 rotates around its own axis, the first nut seat 320, which cooperates with the first lead screw 310, converts the rotation into forward and backward movement along the first direction X. This allows the mounting seats 211 in both clamping mechanisms 210 to move forward and backward along the second slide rail 214. The two grippers 212 located on the mounting seats 211 can clamp one side of the workpiece 900, thus enabling the two clamping mechanisms 210 to clamp the two sides of the workpiece 900 respectively and drive the workpiece 900 as a whole to move forward and backward along the first direction X, thereby achieving conveying.

[0053] In some possible embodiments, see Figure 4As shown, the clamping assembly 200 also includes a third drive mechanism 230; the third drive mechanism 230 is used to drive the two grippers 212 to move closer or further apart along the third direction Z.

[0054] The third drive mechanism 230 can be a cylinder.

[0055] The two grippers 212 on each clamping mechanism 210 are driven directly by the cylinder to move closer or further apart along the third direction Z, thereby achieving the gripping or releasing of the workpiece 900.

[0056] In some other possible embodiments, the two grippers 212 can also be moved closer or further apart along the third direction Z by designing structures such as eccentric wheels, which will not be elaborated in the embodiments of this application.

[0057] In some possible embodiments, see Figures 1 to 6 As shown, the second drive assembly 400 includes a second lead screw 410, a second nut seat 420, a third nut seat 430, a third slide rail 440, and a second drive member 450.

[0058] The second lead screw 410 extends along the second direction Y and is rotatably mounted on the frame 100 about its own axis. The second nut seat 420 and the third nut seat 430 are both screwed onto the second lead screw 410, and the thread directions of the second nut seat 420 and the third nut seat 430 are opposite.

[0059] The third slide rail 440 extends along the second direction Y and is disposed on the frame 100. Two clamping mechanisms 210 are slidably disposed on the third slide rail 440, and the second nut seat 420 is connected to one of the clamping mechanisms 210, and the third nut seat 430 is connected to the other clamping mechanism 210.

[0060] Two clamping mechanisms 210 are slidably mounted on a third slide rail 440. Specifically, a second nut seat 420 is connected to the base plate 215 of one of the clamping mechanisms 210, and a third nut seat 430 is connected to the base plate 215 of the other clamping mechanism 210. The base plate 215 is mounted on the third slide rail 440 via a slider (not shown). Thus, the base plates 215 of the two clamping mechanisms 210 can be guided by the third slide rail 440, allowing the spacing between the two clamping mechanisms 210 along the second direction Y to be adjusted under the drive of the second drive member 450. This enables the feeding mechanism to adapt to flexible substrates of different specifications without the need to replace rollers of different diameters, reducing reliance on manual labor, simplifying installation, reducing errors, effectively reducing debugging time costs, and resulting in higher production efficiency.

[0061] The second drive unit 450 can be a synchronous motor.

[0062] The second lead screw 410 extends along the second direction Y. The second lead screw 410 can be mounted on the frame 100 via a bearing (not shown), so that the second lead screw 410 can rotate around its own axis.

[0063] The second lead screw 410 has two threaded sections with opposite directions. The second nut seat 420 and the third nut seat 430 are arranged with opposite thread directions, so that the second nut seat 420 and the third nut seat 430 can respectively mate with their corresponding threaded sections.

[0064] The second drive component 450 is connected to the second lead screw 410 via a reduction mechanism or directly via a coupling.

[0065] In practice, combining Figure 3 In terms of orientation, when the second driving member 450 drives the second lead screw 410 to rotate clockwise around its own axis, the second nut seat 420, which cooperates with the second lead screw 410, converts the clockwise rotation into a leftward movement along the second direction Y, and the third nut seat 430, which cooperates with the second lead screw 410, converts the clockwise rotation into a rightward movement along the second direction Y. The second nut seat 420 and the third nut seat 430 move closer to each other along the second direction Y, thereby driving the two clamping mechanisms 210 to move closer to each other along the second direction Y.

[0066] When the second driving member 450 drives the second lead screw 410 to rotate counterclockwise around its own axis, the second nut seat 420 cooperating with the second lead screw 410 converts the counterclockwise rotation into a rightward movement along the second direction Y, and the third nut seat 430 cooperating with the second lead screw 410 converts the counterclockwise rotation into a leftward movement along the second direction Y. The second nut seat 420 and the third nut seat 430 move away from each other along the second direction Y, thereby driving the two clamping mechanisms 210 to move away from each other along the second direction Y.

[0067] Thus, by setting up the above mechanism, the width of the workpiece 900 that can be clamped by the two clamping mechanisms 210 can be quickly adjusted, thereby enabling the feeding mechanism to adapt to flexible substrates of different specifications without the need to replace rollers of different diameters, reducing reliance on manpower, simplifying installation, reducing errors, effectively reducing debugging time costs, and making production efficiency higher.

[0068] In some possible embodiments, see Figures 1 to 6 As shown, the first drive assembly 300 also includes a first synchronous pulley 350, a second synchronous pulley 360, and a synchronous belt 370. The first synchronous pulley 350 is disposed at one end of the first lead screw 310, and the second synchronous pulley 360 is disposed on the output shaft of the first drive member 340; the synchronous belt 370 is wound around the first synchronous pulley 350 and the second synchronous pulley 360.

[0069] Power transmission is achieved by setting up a first synchronous pulley 350, a second synchronous pulley 360, and a synchronous belt 370. The power output by the first drive unit 340 is transmitted to the second synchronous pulley 360, which is connected to the first synchronous pulley 350 via the synchronous belt 370. The first lead screw 310 can be a precision-ground lead screw to achieve high-precision repetitive material pulling and positioning. For different flexible motor substrate spacings, the material pulling distance parameter along the first direction X can be directly modified, avoiding the repetitive positioning error and cumulative positioning error caused by roller drive in the prior art. In this way, the feeding mechanism can avoid cumulative error during continuous feeding, resulting in higher conveying accuracy.

[0070] A second aspect of the embodiments of this application provides a feeding system, see below. Figures 1 to 5 As shown, the feeding system includes the aforementioned feeding mechanism and the track 500; the frame 100 of the feeding mechanism is located at one end of the track 500 along the first direction X.

[0071] Among them, track 500 consists of two tracks that extend along the first direction X.

[0072] The track 500 is mounted above the frame 100, and the frame 100 is located at one end of the track 500 along the first direction X. The two tracks 500 are movable along the second direction Y. The two clamping mechanisms 210 are driven to move closer or further apart along the second direction Y by the second drive assembly 400. The spacing between the two tracks 500 along the second direction Y can also be adjusted accordingly, so as to better support the workpiece 900. This allows the feeding system to adapt to flexible substrates of different specifications, effectively reducing debugging time costs and making production efficiency higher.

[0073] A third aspect of the embodiments of this application provides another feeding system, see [link to relevant documentation]. Figures 1 to 4 ,as well as Figure 6 As shown, the feeding system includes two feeding mechanisms as described above and a track 500; the frames 100 of the two feeding mechanisms are respectively disposed at both ends of the track 500 along the first direction X.

[0074] Among them, track 500 consists of two tracks that extend along the first direction X.

[0075] The track 500 is mounted above the frame 100. The two tracks 500 are movable along the second direction Y. The two clamping mechanisms 210 are driven to move closer or further apart along the second direction Y by the second drive component 400. The spacing between the two tracks 500 along the second direction Y can also be adjusted accordingly, so as to better support the workpiece 900. This allows the feeding system to adapt to flexible substrates of different specifications, effectively reducing debugging time costs and making production more efficient.

[0076] In this embodiment, the frames 100 of the two feeding mechanisms are respectively disposed at both ends of the track 500 along the first direction X. Thus, the clamping assemblies 200 of the two feeding mechanisms can respectively clamp the two ends of the workpiece 900 along the first direction X. Figure 6 As shown, the feeding mechanism at the left end pulls the workpiece 900 to the left along the first direction X, while the feeding mechanism at the right end tightens the workpiece 900 and moves it to the left along the first direction X; or, the feeding mechanism at the right end pulls the workpiece 900 to the right along the first direction X, while the feeding mechanism at the left end tightens the workpiece 900 and moves it to the right along the first direction X. In this way, the two feeding mechanisms at both ends can effectively prevent wrinkles from forming on the workpiece 900 during the pulling process.

[0077] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0078] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
