Technical Field

[0001] The utility model belongs to the field of feeding mechanisms, and in particular relates to an automatic feeding device for flexible circuit boards. Background Art

[0002] Currently, electronic products' printed circuit boards (PCBs) are primarily classified by material properties into two types: fiberglass epoxy copper-clad laminates (FR4) and flexible printed circuits (FPCs). These two types work together to form the primary control modules of electronic products. The production process for FR4 PCBs is now quite mature, with virtually full automation possible. However, the production of FPC PCBs still requires manual labor, primarily due to the flexible nature of FPCs, which require support fixtures from the outset.

[0003] At present, traditional flexible circuit board feeding equipment generally uses conveyor belts to transport materials one by one. It requires manual work to continuously place full trays on the conveyor belt and manually remove empty trays from the conveyor belt. Sometimes, there will even be interruptions in feeding. This method has slow feeding speed, high labor costs, and low work efficiency. At the same time, traditional flexible circuit board feeding equipment requires the use of conveyor belts to transport products, which occupies a large area and makes it difficult to install in existing production lines. Therefore, it is necessary to design an automatic flexible circuit board feeding device to solve the above problems. Utility Model Content

[0040] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0041] The utility model provides the following embodiments:

[0042] Automatic feeding device for flexible circuit boards, such as Figure 1 and Figure 2 As shown, it includes a feeding mechanism 1, a loading mechanism 2 and a unloading mechanism 3;

[0043] like Figure 3 As shown, the feeding mechanism 1 is used to transport the material tray to the loading mechanism 2. The feeding mechanism 1 includes a frame 11 with four sets of universal wheels. A placement table 12 for placing the material tray is provided on the top of the frame 11. A gap is left in the middle of the placement table 12 for inserting the rising platform 223. Several groups of baffles 13 are provided around the top of the placement table 12. Multiple groups of material trays are placed and stacked on the placement table 12. The function of the baffles 13 is to block the material trays to prevent them from tilting outward and falling. Then, the feeding mechanism 1 filled with material trays slides to the loading mechanism 2 through the universal wheels.

[0044] like Figure 4 、 Figure 5 Shown and Figure 7As shown, the feeding mechanism 2 includes a frame 21, on which are provided a lifting mechanism 22 for driving the material tray to rise, a fixing mechanism 23 for fixing the material tray, a transport mechanism 24 for driving the material tray to move horizontally, and a positioning mechanism 25 for fixing the feeding mechanism 1;

[0045] like Figure 7 As shown, the positioning mechanism 25 includes a base 251 provided on the bottom side of the frame 21, a positioning plate 252 hinged to the base 251, and a positioning cylinder 253 for driving the distal end of the positioning plate 252 to move up and down. The top of the positioning plate 252 is provided with a groove 254 for engaging with the vehicle frame 11. First, the positioning cylinder 253 drives the positioning plate 252 to move around the hinge between the base 251 and the positioning plate 252 downward. When the feeding mechanism 1 reaches the loading mechanism 2, the positioning cylinder 253 drives the positioning plate 252 upward, causing the groove 254 to engage with the vehicle frame 11 to prevent the vehicle frame 11 from moving.

[0046] The lifting mechanism 22 includes a first slide rail 221 vertically mounted on the frame 21, a first slider 222 sliding along the first slide rail 221, a lifting platform 223 fixedly connected to the slider, and a lifting motor 224 for driving the lifting platform 223 to move up and down. When the frame 11 is stuck by the positioning mechanism 25, the lifting platform 223 is inserted into the gap between the placement tables 12, so that the material tray is exactly on the surface of the lifting platform 223. The lifting motor 224 drives the lifting platform 223 to move upward along the first slide rail 221. At this time, the material tray moves upward along the stop rod 13, and the stop rod 13 also plays a role of limiting to prevent the material tray from tipping over.

[0047] The fixing mechanism 23 includes a frame 231 provided at the top of the frame 21, L-shaped clamping plates 232 provided on opposite sides of the frame 231, and a telescopic cylinder 233 for driving the clamping plates 232 to approach the material tray. A plurality of blocking members 234 are fixed to the top of the frame 231 to prevent the material tray from shaking, and a rubber sleeve 235 is provided at the bottom end of the blocking member 234. The material tray on the rising platform 223 moves upward until the topmost material tray touches the rubber sleeve 235 and stops moving. At this time, the telescopic cylinder 233 drives the clamping plate 232 to move toward the material tray. At this time, the bottom side of the L-shaped clamping plate 232 just abuts against the bottom side of the topmost material tray, and the external machine starts to take the product.

[0048] The transport mechanism 24 includes two sets of horizontal slide rails 241 provided between the frame 21 and the frame 231 and a translation cylinder 242 for driving the frame 231 to move horizontally. When the top tray has taken all the products, the translation cylinder 242 drives the frame 231 to drive toward the down-feeding mechanism 3. At this time, the clamping plate 232 just fixes the top empty tray on the frame 231, and then places the empty tray on the down-feeding mechanism 3. The translation cylinder 242 drives the frame 231 back to the top of the frame 21, and then repeats the loading action.

[0049] like Figure 6 As shown, the unloading mechanism 3 includes a movable frame 31 hinged to the frame 21, and a descending mechanism 32 is provided on the movable frame 31 for driving the empty material tray to descend; the descending mechanism 32 includes a second slide rail 321 vertically fixed to the movable frame 31, a second slider 322 slidably connected to the second slide rail 321, a descending platform 323 fixedly connected to the second slider 322, and a descending cylinder 324 for driving the descending platform 323 to slide vertically; a waste box 325 for placing unqualified products is provided at the top of the movable frame 31; first, the descending cylinder 324 Drive the descending platform 323 to rise to the top of the movable frame 31. When the empty material tray is transported to the movable frame 31 by the conveying mechanism, the external machine first clamps the unqualified products in the empty material tray into the waste box 325, and then the telescopic cylinder 233 moves away from the material tray, releasing the fixation of the material tray by the clamping plate 232. At this time, the empty material tray just falls onto the descending platform 323, and then the descending cylinder 324 drives the descending platform 323 to descend little by little until the empty material tray is full or all the products are fed, and the empty material tray is taken out, and finally the entire feeding work is completed.

[0050] To sum up, first of all, the whole device is in Figure 2 When feeding is required, the unloading mechanism 3 is opened to the right, and then the feeding mechanism 1 is released from the positioning mechanism 25 and moved outward, finally forming the following Figure 1 After the feeding mechanism 1 is loaded onto the feeding tray, the feeding mechanism 1 is pushed onto the feeding mechanism 2 and positioned by the positioning mechanism 25, and then the unloading mechanism 3 is moved back to Figure 2 The cooperation between the feeding mechanism 1, the loading mechanism 2 and the unloading mechanism 3 can feed materials uninterruptedly, saving a lot of manpower and improving work efficiency. In addition, this vertical setting can effectively save site space.

[0051] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
