Description

TECHNICAL FIELD

[0002] Flexible Printed Circuit (FPC, also known as FPCB) is a kind of flexible printed circuit board with high reliability and excellent flexibility, which is made of polyimide or polyester film. It has the characteristics of high wiring density, light weight, thin thickness and good bending property. With the explosive growth of wearable devices, flexible display and smart devices, the demand for flexible circuit boards has increased significantly, and the industry is being used more and more widely. In the context of electronic products pursuing light, thin, short and small design, ultra-thin and stretchable flexible circuit boards are widely used.

[0003] In production, FPC needs to be taken out from the tray and handed over to the attaching head.

[0004] Moreover, taking FPC out of the tray and handing it over to the attaching head, since there are certain defective products in the incoming FPC, directly attaching will produce defective products, which will also affect the product yield. Invention content

[0057] In order to facilitate the implementation of the first direction driving calibration template device 200, in some embodiments, the first direction driving device 100 comprises a support assembly, a driving assembly, a transmission assembly and a moving assembly; the calibration template device 200 is arranged on the moving assembly; the driving assembly is arranged on the support assembly, and is connected with the moving assembly through the transmission assembly, and is used to drive the transmission assembly to drive the moving assembly to move, so as to drive the calibration template device 200 to move. As an example, as shown in Figure 6 and Figure 7As shown, the support assembly comprises a base 101, a support plate 102, a rib plate 103 and a fixing seat 104, the driving assembly is arranged on the fixing seat 104, the fixing seat 104 is arranged on the base 101 through the support plate 102, and the support plate 102 is connected to the support plate 102 through the rib plate 103; and / or the moving assembly comprises a lead screw module 105 and a driving seat 106, a fixed part of the lead screw module 105 is arranged on the support assembly or the fixing seat 104 of the support assembly, and the driving seat 106 is arranged on a sliding seat of the lead screw module 105; the calibration template device 200 or the second direction fine movement platform 201 of the calibration template device 200 is arranged on the moving assembly or the driving seat 106 of the moving assembly; the driving assembly comprises a motor seat 107 and a servo motor 108, and the servo motor 108 is arranged at one end of the support assembly or the fixing seat 104 through the motor seat 107; the transmission assembly comprises a module synchronous wheel 110, a synchronous belt 111 and a motor synchronous wheel 112, the module synchronous wheel 110 is connected to the motor synchronous wheel 112 through the synchronous belt 111, the module synchronous wheel 110 is connected to the moving assembly or the lead screw module 105 of the moving assembly, and the motor synchronous wheel 112 is connected to the driving assembly or the servo motor 108 of the driving assembly.

[0058] Such a structural design, on the one hand, through the cooperation of the base 101, the support plate 102, the rib plate 103 and the fixing seat 104, the flexible circuit board pretreatment device 500 as a whole can be stably fixed or installed through the first direction driving device 100, and the moving assembly can be easily assembled on the support assembly.

[0059] On the other hand, the first direction driving device 100 drives the calibration template device 200 to move along the extension and retraction direction of the lead screw of the lead screw module 105, that is, the first direction, so as to drive the flexible circuit board 400 adsorbed by the calibration template device 200 to move along the first direction to the shooting position of the vision device 300 for shooting.

[0060] On the other hand, through the cooperation of the module synchronous wheel 110, the synchronous belt 111 and the motor synchronous wheel 112, the servo motor 108 and the lead screw module 105, it is beneficial to convert the output of the servo motor 108 into control of the lead screw module 105 in a relatively small space, so as to drive the flexible circuit board 400 to move.

[0061] On the other hand, cooperating with the background control and processing, the image of the product can be captured by the vision, and the defective products can be screened out in advance, so as to save the production time and improve the product yield.

[0062] In some embodiments, as shown in Figure 6 and Figure 7 The first direction driving device 100 further comprises a protective cover 109 covering the transmission assembly. Such a design is advantageous in that it protects the module synchronization wheel 110, the synchronization belt 111 and the motor synchronization wheel 112 in a relatively closed space, thereby providing appropriate protection and avoiding safety risks to other structural components or operators when the module synchronization wheel 110, the synchronization belt 111 and the motor synchronization wheel 112 are in a transmission state.

[0063] In some embodiments, as shown in Figure 6 The first direction driving device 100 further comprises a tow chain bracket 113, a tow chain 114 and a tow chain support plate 115. The tow chain support plate 115 is arranged on the support assembly or the fixing seat 104 of the support assembly. The tow chain 114 is arranged on the moving assembly or the driving seat 106 of the moving assembly through the tow chain bracket 113. Such a design is advantageous in that it protects and links the lines, so that the first direction driving device 100 can arrange the lines as required to achieve electrical connection of structural components such as the servo motor 108.

[0064] In some embodiments, as shown in Figure 8 The calibration template device 200 comprises a second direction micro-motion platform 201, an angle rotation micro-motion platform 202, a template mounting seat 203 and a product template 204. The second direction micro-motion platform 201 is arranged on the first direction driving device 100. The angle rotation micro-motion platform 202 is arranged on the second direction micro-motion platform 201. The template mounting seat 203 is arranged on the angle rotation micro-motion platform 202. The product template 204 is detachably arranged on the template mounting seat 203 and is used to adsorb the flexible circuit board 400. In some embodiments, the first direction driving device 100 and the second direction micro-motion platform 201 each have a motor and a lead screw structure. The motor controls the lead screw to convert rotary output into linear motion output, thereby achieving linear motion control. As an example, the first direction driving device 100 is used to drive the calibration template device 200 to move in a first direction. The second direction micro-motion platform 201 is used to drive the angle rotation micro-motion platform 202 to move in a second direction. The first direction and the second direction have a preset included angle. In some embodiments, the preset included angle is 70 to 120 degrees. As an example, the preset included angle is 90 degrees.

[0065] The structure design is beneficial to quickly assemble the calibration template device 200 and conveniently adsorb the flexible circuit board 400. On the other hand, under the premise of moving the flexible circuit board 400 for shooting, the position of the product template 204 can be adjusted according to the product image analysis result of the flexible circuit board 400 in the background, so as to adjust the position of the flexible circuit board 400. Therefore, it is beneficial to adjust the position of the product template 204 in multiple directions and angles, so as to realize the accurate adjustment of the position of the flexible circuit board 400, including the position adjustment of the first direction driving device 100, the position adjustment of the second direction micro-motion platform 201, and the angle direction adjustment of the angle rotating micro-motion platform 202. That is, through the multi-dimensional adjustment control of the first direction, the second direction and the angle direction, the position of the flexible circuit board 400 is accurate in the subsequent process, so as to ensure the position accuracy of the flexible circuit board transferred to the pressing head, thereby greatly improving the attachment stability and precision.

[0066] In order to save the process and reduce the complexity of the structure and process, in some embodiments, the product template 204 has a transparent plate, and the vision device 300 or the camera lens assembly 308 of the vision device 300 is located below the product template 204 to shoot the product image of the flexible circuit board 400 from below the product template 204. Such a structure design is beneficial to the product template 204 adsorbing the flexible circuit board 400, without the need for position rotation, which can meet the shooting requirements of the vision device 300 located below the product template 204. This saves the additional motor rotation process, optimizes the product structure, reduces the complexity of the structure and process, and is beneficial to saving the process and improving the processing efficiency.

[0067] In some embodiments, as shown in Figure 9 The vision device 300 includes an adjusting structure, a connecting structure, a fixing structure and a camera lens assembly 308. The camera lens assembly 308 is arranged on the fixing structure, the fixing structure is arranged on the adjusting structure through the connecting structure, and the adjusting structure is used to adjust the position of the camera lens assembly 308. In some embodiments, as shown in Figure 9As shown, the adjustment structure includes an adjustment base 301, a first-direction adjustment slide 302, and a second-direction adjustment slide 303. The first-direction adjustment slide 302 is disposed on the adjustment base 301, and the second-direction adjustment slide 303 is disposed on the first-direction adjustment slide 302. The connecting structure is disposed on the second-direction adjustment slide 303. Alternatively, the connecting structure includes a connecting plate 304 and a connecting plate 305 connected together. The connecting plate 304 is disposed on the adjustment structure or the second-direction adjustment slide 303 of the adjustment structure, and the connecting plate 305 is connected to the fixing structure. As an example, the connecting plate 305 is connected to the camera fixing plate 306 of the fixing structure. And / or, the fixing structure includes a camera fixing plate 306, a camera mount 307, and a lens fixing plate 309. The camera fixing plate 306 is connected to the connecting structure or the connecting plate 305 of the connecting structure. The camera mount 307 is disposed on the camera fixing plate 306. The lens fixing plate 309 and the camera lens assembly 308 are both disposed on the camera mount 307, and the lens of the camera lens assembly 308 is limited to the lens fixing plate 309. For example, the connecting plate 305 is connected to the camera fixing plate 306, and the adapter plate 304 is connected to the second direction adjustment slide 303, which facilitates the assembly of the vision device 300.

[0068] This structural design facilitates the movement of the flexible circuit board 400 for imaging, thereby obtaining product images of the flexible circuit board 400 for backend analysis. Furthermore, the coordinated operation of the first direction driving device 100, calibration template device 200, and vision device 300 allows for easy adjustment of the imaging position of the flexible circuit board 400, ensuring the quality of the product images. These images can then be used as high-precision images for backend analysis and processing. Therefore, by visually capturing product images, defective products can be screened out in advance, saving production time and improving product yield. Additionally, the flexible circuit board pre-processing device 500 can adjust the position of the flexible circuit board 400 according to backend requirements for transfer, ensuring the accuracy of the flexible circuit board's position on the pressure head, thus greatly improving adhesion stability and accuracy.

[0069] In order to provide illumination, in this embodiment, such as Figure 9 As shown, the vision device 300 also includes a light source base 310 and a light source 311; the light source 311 is disposed on the light source base 310, and the light source base 310 is disposed on the fixed structure or the camera mounting plate 306 of the fixed structure. This structural design is beneficial for providing auxiliary lighting for the camera lens assembly 308, enabling the camera lens assembly 308 to achieve better shooting results.
