[0086] The FPC appearance inspection machine in the prior art is not convenient to be installed in the FPC, and the FPC appearance inspection machine is large in size and occupies a large space.

[0087] The following is a preferred embodiment of an FPC appearance inspection machine provided by the utility model that can solve the above technical problems.

[0088] Please refer to Figure 1 The preferred embodiment of the utility model provides an FPC appearance inspection machine, which includes an FPC unloading and receiving device, a main shooting module 3, a tape connection mechanism 4 and a re-inspection mechanism 5. The FPC unloading and receiving device includes a support mechanism 1 and two sets of FPC transmission mechanisms 2.

[0089] The supporting mechanism 1 comprises a supporting main wheel 11 and two supporting auxiliary wheels 12 . The two supporting auxiliary wheels 12 are arranged in a transverse direction and are spaced apart. The supporting main wheel 11 is spaced apart and arranged above the two supporting auxiliary wheels 12 .

[0090] Please refer to Figure 1 and Figure 4, two sets of FPC transmission mechanisms 2 are symmetrically arranged on the lateral sides of the support mechanism 1, and the FPC transmission mechanism 2 includes a main shaft 21 for placing the FPC roll, a driving assembly 22, a first guide wheel 23, and a tension test assembly 24. The driving assembly 22 is used to drive the main shaft 21 to rotate, and includes a stepping motor 221, a synchronous belt 222, a driving wheel 223 and a driven wheel 224. The driving wheel 223 is connected to the rotating shaft of the stepping motor 221, and the driven wheel 224 is connected to the main shaft 21. The synchronous belt 222 is sleeved on the driving wheel 223 and the driven wheel 224. The first guide wheel 23 and the tension test assembly 24 are respectively located on the lateral sides above the main shaft 21, and the tension test assembly 24 is close to the support mechanism 1 relative to the first guide wheel 23. The FPC on the main shaft 21 passes through the side of the first guide wheel 23 away from the supporting main wheel 11, the tension test assembly 24, the lower side of one supporting auxiliary wheel 12, the upper side of the supporting main wheel 11 and the lower side of the other supporting auxiliary wheel 12 in sequence. The FPC is straight between the first guide wheel 23 and the tension test assembly 24.

[0091] Please refer to Figure 1 The main shooting module 3 is arranged above the supporting main wheel 11 to take pictures of the FPC passing above the supporting main wheel 11 to detect the appearance of the FPC.

[0092] Please refer to Figure 1 and Figure 7 The tape splicing mechanism 4 is located between the first guide wheel 23 of a group of FPC conveying mechanisms 2 and the tension test assembly 24. The tape splicing mechanism 4 includes a carrier plate 41 and two clamping assemblies 42. The carrier plate 41 is horizontally arranged, and a cutting groove 411 extending in the longitudinal direction is arranged on its top surface. The two clamping assemblies 42 are respectively arranged on both sides of the cutting groove 411, and are used to press the FPC on the top surface of the carrier plate 41. If the tape splicing is required, the tail of the front roll of FPC is pressed on the top surface of the carrier plate 41 by the clamping assembly 42 close to the tension test assembly 24, and the tail of the front roll of FPC is manually cut at the cutting groove 411, and the head of the rear roll of FPC is pressed on the top surface of the carrier plate 41 by the clamping assembly 42 close to the first guide wheel 23, and the end of the rear roll of FPC is manually cut at the cutting groove 411, so that both parts become flush, and the two parts are manually pasted with adhesive tape. With the above structure, it is only necessary to wind the front section of the FPC around the first guide wheel 23 and complete the connection between the FPCs through the belt connection mechanism 4, thereby facilitating the installation of the FPCs.

[0093] Please refer to Figure 1 and Figure 2The re-inspection mechanism 5 includes a re-inspection camera 51 and a re-inspection drive assembly 52. ​​The re-inspection camera 51 is arranged above the first guide wheel 23 and the tension test assembly 24 of another set of FPC conveying mechanism 2. The re-inspection drive assembly 52 is connected to the re-inspection camera 51 to drive the re-inspection camera 51 to move longitudinally. If the FPC needs to be re-tested, the FPC is reversely conveyed so that the place to be re-tested is located between the corresponding tension test assembly 24 and the first guide wheel 23, and the appearance inspection is performed through the re-inspection camera 51.

[0094] In the FPC unwinding and receiving device of the utility model, the FPC passes through the first guide wheel 23 and the tension test assembly 24 of the FPC transmission mechanism 2 from the main shaft 21 of one group of FPC transmission mechanisms 2, then passes through the bottom of a supporting secondary wheel 12, the top of the supporting main wheel 11 and the bottom of another supporting secondary wheel 12, and then passes through the tension test assembly 24 and the first guide wheel 23 of another group of FPC transmission mechanisms 2, and finally is wound through the main shaft 21 of the FPC transmission mechanism 2; the tension test assembly 24 can test the tension of the FPC, so as to timely adjust the two main shafts 21 The rotation speed of the FPC can keep the appropriate tension of the FPC; the FPC unloading and receiving device of the utility model can, through the layout of the supporting mechanism 1 and the two sets of FPC conveying mechanisms 2, set the main shooting module 3 above the supporting main wheel 11 to facilitate the shooting of the FPC, and can also locate the tape connection mechanism 4 and the re-inspection mechanism 5 in a straight state at a higher position during the FPC conveying process, so that the staff can connect the tape conveniently, and the re-inspection camera 51 can shoot the FPC in a straight state to ensure the accuracy of the re-inspection; and the supporting mechanism 1 and the two sets of FPC conveying mechanisms 2 are reasonably arranged and compact in structure, which effectively saves the installation space.

[0095] Please refer to Figure 1 and Figure 4, the FPC transmission mechanism 2 also includes a second guide wheel 25, a correction sensor 26 and a correction assembly 27. The second guide wheel 25 is arranged directly below the first guide wheel 23 and is located obliquely above the main shaft 21. The correction sensor 26 is arranged between the first guide wheel 23 and the second guide wheel 25, and an edge of the FPC is vertically penetrated through the correction sensor 26. The correction assembly 27 is connected to the main shaft 21, the second guide wheel 25 and the correction sensor 26. The correction assembly 27 drives the main shaft 21, the second guide wheel 25 and the correction sensor 26 to move to the corresponding position in the longitudinal direction according to the depth of the FPC in the correction sensor 26 to adjust the edge position of the FPC. The edge of the FPC roll is usually misaligned. If the main shaft 21 is always in a fixed position, the position of the FPC on the supporting main wheel 11 will be offset, resulting in an incomplete FPC image captured by the main shooting module 3. In the above structure, the positions of the main shaft 21, the second guide wheel 25 and the correction sensor 26 are relatively fixed. If the edges of the FPC are aligned, the depth of the FPC in the correction sensor 26 is the standard depth, and the main shaft 21, the second guide wheel 25 and the correction sensor 26 are in the standard position in the longitudinal direction. If the edges of the FPC are not aligned, the main shaft 21, the second guide wheel 25 and the correction sensor 26 are driven to move to the corresponding position in the longitudinal direction through the correction component 27 according to the difference between the depth of the FPC in the correction sensor 26 and the standard depth, so that the FPC is in the corresponding position in the longitudinal direction. Through the above structure, the position of the FPC in the longitudinal direction can be adjusted in real time, so that the FPC is always in a suitable position when it is transferred to the supporting main wheel 11. By setting the second guide wheel 25, the FPC passing through the correction sensor 26 can be always in the vertical direction, so as to accurately obtain the displacement required for correction.

[0096] Please refer to Figure 4 and Figure 5, the FPC appearance inspection machine also includes a base 9. The correction component 27 includes a sliding plate 271, a vertical plate 272 and a correction cylinder 273. The sliding plate 271 is slidably connected to the base 9 in the longitudinal direction, and the main shaft 21 and the driving component 22 are fixedly connected to the top surface of the sliding plate 271. The vertical plate 272 is fixedly connected to the top surface of the sliding plate 271 and is located on the side of the main shaft 21 away from the support mechanism 1. The second guide wheel 25 and the correction sensor 26 are both connected to the top of the vertical plate 272. The correction cylinder 273 is arranged on the top surface of the base 9 and is located on the side of the sliding plate 271 close to the support mechanism 1. The correction cylinder 273 is connected to the edge of the sliding plate 271, and is used to drive the sliding plate 271, the second guide wheel 25, the correction sensor 26, the main shaft 21 and the driving component 22 to move in the longitudinal direction. With the above structure, the correction cylinder 273 can drive the sliding plate 271 to slide in the longitudinal direction, thereby driving the second guide wheel 25, the correction sensor 26, the main shaft 21 and the driving assembly 22 to move in the longitudinal direction. The main shaft 21 and the driving assembly 22 are both fixedly connected to the top surface of the sliding plate 271, and the second guide wheel 25 and the correction sensor 26 are both connected to the top of the vertical plate 272, so that the height of the second guide wheel 25 and the correction sensor 26 can be higher than the height of the main shaft 21, and the structure is also relatively compact.

[0097] Please refer to Figure 4 and Figure 6 The deflection correction assembly 27 also includes a mounting assembly 274, which includes a square deflection correction rod 2741, a connecting seat 2742, three fixing screws 2743, a circular connecting column 2744 and a mounting strip 2745.

A square lower through hole is provided at the bottom of the connecting seat 2742, and a circular upper through hole is provided at the top thereof. The axes of the lower through hole and the upper through hole are both longitudinal. The correction rod 2741 is penetrated through the lower through hole, and the connecting column 2744 is penetrated through the upper through hole. A fixing screw 2743 is penetrated through the side wall of the lower through hole and abuts against the correction rod 2741, which is used to limit the lateral position of the correction rod 2741. A fixing screw 2743 is penetrated through the wall at the bottom of the lower through hole and abuts against the correction rod 2741, which is used to limit the vertical position of the correction rod 2741. Another fixing screw 2743 is penetrated through the wall of the upper through hole and abuts against the connecting column 2744, which is used to limit the connecting column 2744. The mounting bar 2745 is vertically connected to one end of the connecting column 2744 . The mounting bar 2745 is provided with a mounting hole 27451 extending along the length direction of the mounting bar 2745 . The deviation correction sensor 26 is screwed through the mounting hole 27451 and connected to the mounting bar 2745 .

[0098] By adopting the above structure, the connection seat 2742 can be moved to a suitable position along the correction rod 2741, and then the two corresponding fixing screws 2743 are tightened to fix the connection seat 2742 on the correction rod 2741, so as to adjust the longitudinal position of the correction sensor 26; then the connection column 2744 is rotated, and the corresponding fixing screws 2743 are tightened to fix the connection column 2744 on the connection seat 2742, so as to adjust the horizontal and vertical positions of the correction sensor 26; finally, the correction sensor 26 is placed at a suitable position corresponding to the mounting hole 27451, and the correction sensor 26 is fixed to the mounting bar 2745 by screws, so as to fine-tune the horizontal and vertical positions of the correction sensor 26.
