Description

Technical Field

[0001] The utility model relates to the technical field of circuit board feeding equipment, in particular to an automatic circuit board feeding machine. Background Art

[0002] Circuit boards, also known as printed circuit boards, or PCBs for short, are widely used in a variety of electronic devices, such as computers, mobile phones, and household appliances. Circuit boards are the support and electrical connection carrier for electronic components, providing a fixed installation location for various electronic components and achieving electrical connections between components through conductive wiring, making the assembly of electronic equipment more compact and reducing the volume. The integrated structure also reduces errors and failures in manual wiring.

[0003] Circuit boards need to go through multiple processes during production. When the circuit boards enter the next process for processing, a feeder is often used to feed the circuit boards. The current circuit board feeder uses a feed frame to separate the circuit boards, and then pushes the circuit boards to the next level conveyor belt through a push plate mechanism to complete the feeding. When the feed frame is empty, the empty frame is manually taken out and a new frame is placed. This process is not fast enough, takes a long time, and easily affects production efficiency.

[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] Please see attached Figure 1 - Figure 5 As shown, the automatic circuit board feeding machine in the embodiment of the utility model includes a lifting mechanism 1 and a pushing plate mechanism 4. A lifting and conveying seat 2 is fixed on the inner side of the lifting mechanism 1. Transfer vehicles 5 are arranged on both sides of the lifting and conveying seat 2. The lifting mechanism 1 is arranged to drive the lifting and conveying seat 2 to lift and lower. One of the two transfer vehicles 5 is used to transfer a fully loaded material frame 3, and the other is used to receive an empty frame.

[0035] The lifting and conveying seat 2 includes two first outer frames 21 , and a plurality of first rollers 22 are rotatably connected between the two first outer frames 21 . Output components 24 are arranged on both sides of the first outer frame 21 .

[0036] The output assembly 24 includes a bevel gear 1 241 and a bevel gear 242 that mesh with each other. The bevel gear 242 is fixedly connected with a hexagonal slot 243. The hexagonal slot 243 is rotatably connected to the first outer frame 21. When the actively rotating first roller 22 rotates, the hexagonal slot 243 is driven to rotate through the transmission of the bevel gear 1 241 and the bevel gear 2 242.

[0037] The transfer vehicle 5 includes a transfer conveying seat 51 , and the transfer conveying seat 51 includes two second outer frames 511 . A transmission assembly 514 is disposed inside the second outer frame 511 close to the output assembly 24 .

[0038] The transmission assembly 514 includes a bevel gear three 5141 and a bevel gear four 5143 that are meshed with each other. The bevel gear four 5143 is fixed with a hexagonal shaft 5142. The outer end of the hexagonal shaft 5142 is plugged into the hexagonal slot 243. Since the hexagonal shaft 5142 is plugged into the hexagonal slot 243, when the hexagonal slot 243 rotates, the hexagonal shaft 5142 can be driven to rotate together. Through the transmission of the bevel gear three 5141 and the bevel gear four 5143, the second rollers 512 on both sides are driven to rotate, and then the material frame 3 is transferred.

[0039] After the lifting and conveying seat 2 is started, it will drive the transfer conveying seats 51 of the transfer vehicles 5 on both sides to transmit in the same direction, thereby moving the loading frame 3 from the transfer vehicle 5 on one side to the lifting and conveying seat 2, and the empty material frame 3 on the lifting and conveying seat 2 will be transferred to the transfer vehicle 5 on the other side, thereby completing the operation of replacing the material frame 3.

[0040] In addition, due to the plug-in connection between the hexagonal shaft 5142 and the hexagonal slot 243, the transfer cart 5 can be quickly separated and connected without affecting the transportation of the transfer cart 5. The transfer cart 5 can be easily pushed away after use to carry out the next material frame 3 transportation or empty frame transfer work. The transfer cart 5 uses the motor 27 inside the lifting and conveying seat 2 as the power source, and there is no need to install an additional power source, so the use cost is low.

[0041] The lifting mechanism 1 includes a frame 11, two motor modules 12 are fixed on one side of the frame 11, and the slides of the two motor modules 12 are fixedly connected to the adjacent first outer frame 21.

The inner side of the connecting frame 41 is slidably connected to a mounting platform 42. A pushing cylinder 43 is fixed to the upper end surface of the mounting platform 42, and a pushing head 44 is fixed to the protruding end of the pushing cylinder 43. When feeding, the lifting mechanism 1 drives the material frame 3 to move upward to the pushing area through the lifting and conveying seat 2, and then the pushing cylinder 43 performs a push and retreat, and the pushing head 44 pushes the circuit board inside the material frame 3 out of the material frame 3. After a circuit board is pushed out, the lifting mechanism 1 rises again until the next circuit board is at the pushing height, and the pushing cylinder 43 moves again to push the circuit board, and the circuit board feeding is performed reciprocatingly for multiple times.

[0045] A screw rod 45 is rotatably connected to the middle of the inner side of the connecting frame 41 , and the lower part of the mounting platform 42 is sleeved with the screw rod 45 . When in use, the ejection position of the push cylinder 43 is adjusted by rotating the screw rod 45 .
