Description

Technical Field

[0001] The present application relates to the technical field of circuit board processing, and in particular to an automatic loading machine. Background Art

[0002] The names of circuit boards include: ceramic circuit board, alumina ceramic circuit board, aluminum nitride ceramic circuit board, circuit board, PCB board, aluminum substrate, high-frequency board, thick copper board, impedance board, PCB, ultra-thin circuit board, ultra-thin circuit board, printed circuit board, etc. Circuit boards miniaturize and visualize circuits, and play an important role in the mass production of fixed circuits and the optimization of electrical appliance layout. Circuit boards can be called printed circuit boards or printed circuit boards. FPC circuit boards are also called flexible circuit boards. Flexible circuit boards are made of polyimide or polyester film as a substrate and are highly reliable and extremely flexible printed circuit boards with the characteristics of high wiring density, light weight, thin thickness and good bendability.

[0003] In order to continuously process the circuit boards, at this stage, loading equipment is needed to continuously transfer the circuit boards to the processing station.

[0004] Conveyor belts are commonly used in the prior art to transport circuit boards. However, when the conveyor belt moves too fast or the friction coefficient between the circuit board and the conveyor belt is large, static electricity may be generated. The accumulation of static electricity may cause damage to the surface of the circuit board. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this application is to provide an automatic loading machine for solving the technical problem of damage to the surface of the circuit board caused by friction between the conveyor belt and the circuit board.

[0006] The above-mentioned object of the present application is achieved through the following technical solutions: An automatic feeding machine, comprising a transmission mechanism, a working mechanism arranged on the transmission mechanism, and a recovery mechanism arranged at the end of the transmission structure, wherein the transmission mechanism comprises a pair of L-shaped brackets, and the L-shaped brackets are arranged in a mirror image, and a through slot is provided on a plate of each L-shaped bracket parallel to the ground, and transmission shafts are evenly arranged in the through slots, and the transmission shafts are parallel to the ground and rotatably connected in the through slots, and at the same time pass through the L-shaped brackets, and transmission wheels are fixedly arranged on the transmission shafts, and a connecting plate is fixedly provided at the bottom of the L-shaped bracket, and a base is installed at the bottom of the connecting plate, and a motor base is fixedly provided on the end of the base away from the recovery mechanism, and a driving motor is fixedly provided on the upper end of the motor base, and an intermittent gear is fixedly provided on the output end of the driving motor, and a connecting shaft is fixedly extended on the transmission shaft of the L-shaped bracket away from the recovery mechanism, and a rotating rod is installed between the two connecting shafts, and a transmission gear is fixedly provided in the middle of the rotating rod, and the transmission gear is meshed with the intermittent gear, and a synchronous belt is sleeved on each side of the transmission shaft.

[0007] By adopting the above technical solution, when loading is required, the circuit board is placed on the L-shaped bracket, the drive motor is started to drive the intermittent gear to drive the driven gear, so that the transmission rod drives the connecting shafts on both sides, and the transmission shaft rotates. At this time, the synchronous belt will synchronously drive all the transmission shafts in the same row, drive the transmission wheel to rotate, and let the circuit board move to the bottom of the working mechanism. Since there are only a few intermittent gears on the drive motor, the transmission mechanism will move intermittently, leaving time for the working mechanism to process the circuit board. In this application, the transmission wheel is used instead of the conveyor belt of the prior art, thereby reducing the friction on the surface of the circuit board, so that it can reduce the wear on the circuit board.

[0008] Furthermore, an adjusting stud is provided on a pair of the connecting plates, one end of the adjusting stud is threadedly connected to one connecting plate, and the other end is rotatably connected to the other connecting plate, and connecting columns are inserted on both ends of the pair of connecting plates.

[0009] By adopting the above technical solution, by adjusting the setting of the stud, when the adjusting stud is rotated, the distance between the connecting plates will be changed, thereby changing the distance of the upper L-shaped bracket, so that it can adapt to circuit boards of various sizes.

[0010] Furthermore, the interior of the rotating rod is hollow and has a pair of plug-in slots, which are opened in the length direction. A plug-in block matching the plug-in slots is fixedly provided on the connecting shaft, and the rotating rod is plugged into the connecting shafts on both sides.

[0011] By adopting the above technical solution, since the adjusting stud is adjusted, the rotating rods at both ends of the driving motor need to be removed and the size changed. For greater convenience, in this application, the connecting shaft and the rotating rods on both sides are connected to make it a retractable structure. At the same time, the setting of the plug-in block and the plug-in slot ensures that the rotation of the rotating rod can drive the plug-in shafts at both ends.

[0012] Furthermore, a power-assisting rubber is fixedly provided on one end of the adjusting stud.

[0013] By adopting the above technical solution, it is convenient for the staff to adjust the adjusting bolt during adjustment.

[0014] Furthermore, an anti-slip coating is fixedly provided on the outer side of the transmission wheel.

[0015] By adopting the above technical solution and providing an anti-skid coating on the transmission wheel, it is ensured that the transmission wheel can normally drive the circuit board to move.

[0016] Furthermore, limiting rings fixedly connected to the rotating rod are provided on both sides of the transmission gear, and a pair of limiting plates are fixedly provided on the upper end of the motor base. The upper ends of the limiting plates are provided with slots for plugging into the limiting rings, and the limiting plates and the limiting rings are clamped.

[0017] By adopting the above technical solution, after adjusting the distance between the connecting plates, the rotating rod may be offset, resulting in the intermittent meshing of the teeth and the driven teeth being unable to engage. Therefore, in this application, the limiting rings and limiting plates at both ends are clamped together. Since the limiting plates are fixed, the limiting rings cannot move, thereby ensuring that the position of the rotating rod remains unchanged.

[0018] Furthermore, the recycling structure includes a recycling box fixedly connected to the base and an inclined plate, wherein the inclined plate is fixedly connected to the recycling box and tilted upward to lean against the L-shaped bracket.

[0019] By adopting the above technical solution and providing the recycling box and the tilting plate, it can be ensured that the circuit boards are collected together after being processed.

[0020] Furthermore, the L-shaped bracket is made of carbon steel.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. The use of transmission wheels instead of conveyor belts for circuit board transmission significantly reduces direct contact and friction with the circuit board surface, thereby reducing the risk of wear and scratches on the circuit board surface and effectively protecting the quality of the circuit board.

[0023] 2. By adjusting the stud design, users can easily adjust the distance between the two L-shaped brackets to accommodate circuit boards of different sizes. This adjustability allows the equipment to flexibly respond to diverse production needs, improving its versatility and efficiency.

[0024] 3. The plug-in design of the rotating rod and connecting shaft, as well as the clip-on design of the limit ring and limit plate, make the equipment easier to operate when size adjustment or maintenance is required. These innovative structures not only simplify the maintenance process, but also improve the stability and reliability of the equipment, reducing maintenance costs and time.

[0030] The present application is further described in detail below with reference to the accompanying drawings.

[0031] Example, see Figure 1 、 Figure 2 , an automatic feeding machine includes a transmission mechanism, a working mechanism 5 arranged on the transmission mechanism and a recovery mechanism arranged at the end of the transmission structure. The transmission mechanism includes a pair of L-shaped brackets 1, and the L-shaped brackets are arranged in a mirror image. Each L-shaped bracket 1 is provided with a through slot on a plate parallel to the ground. A transmission shaft 11 is evenly arranged in the through slot. The transmission shaft 11 is parallel to the ground and is rotatably connected in the through slot and passes through the L-shaped bracket 1. A transmission wheel 12 is fixedly arranged on the transmission shaft 11. A connecting plate 2 is fixedly provided at the bottom of the L-shaped bracket 1. The bottom of the connecting plate 2 is installed There is a base 3, and a motor base 21 is fixedly provided on the end of the base 3 away from the recovery mechanism. A drive motor 22 is fixedly provided on the upper end of the motor base 21, and an intermittent meshing gear 23 is fixedly provided on the output end of the drive motor 22. A connecting shaft 24 is fixedly extended from the transmission shaft 11 at one end of the L-shaped bracket 1 away from the recovery mechanism. A rotating rod 25 is installed between the two connecting shafts 24. A transmission meshing gear 26 is fixedly provided in the middle of the rotating rod 25. The transmission meshing gear 26 is meshed and connected with the intermittent meshing gear 23. A synchronous belt 13 is provided on the transmission shaft 11 on each side.

[0032] When loading is required, the circuit board is placed on the L-shaped bracket 1, and the drive motor 22 is started to drive the intermittent gear 23 to drive the driven gear, so that the transmission rod drives the connecting shafts 24 on both sides, and the transmission shaft 1 rotates. At this time, the synchronous belt 13 will synchronously drive all the transmission shafts 1 in the same row, driving the transmission wheel 12 to rotate and let the circuit board move to the bottom of the working mechanism 5. Since there are only a few intermittent gears 23 on the drive motor 22, the transmission mechanism will be intermittent, leaving time for the working mechanism 5 to process the circuit board. In this application, the transmission wheel 12 is used instead of the conveyor belt of the prior art, thereby reducing the friction on the surface of the circuit board, so that it can reduce the wear on the circuit board.

[0033] In this embodiment, a pair of connecting plates 2 are provided with adjustment studs 31. One end of the adjustment stud 31 is threaded onto one connecting plate 2, and the other end is pivotally connected to the other connecting plate 2. Connecting posts 32 are inserted into both ends of the connecting plates 2. By rotating the adjustment studs 31, the distance between the connecting plates 2 changes, thereby varying the distance between the upper L-shaped brackets 1, making it suitable for circuit boards of various sizes.

[0034] In this embodiment, the rotating rod 25 is hollow and has a pair of slots extending along its length. A plug-in block that matches the slots is fixedly mounted on the connecting shaft 24. The rotating rod 25 plugs into the connecting shafts 24 on both sides. Since the adjusting screw 31 is adjusted, the rotating rods 25 at both ends of the drive motor 22 need to be removed to change their size. For greater convenience, the present application utilizes a connecting shaft 24 plugged into the rotating rods 25 on both sides, creating a retractable structure. The plug-in blocks and slots ensure that the rotating rod 25 can drive the plug-in shafts on both ends when it rotates.

[0035] In this embodiment, one end of the adjusting stud 31 is fixedly provided with a booster rubber, which is convenient for the staff to adjust the adjusting bolt.

[0036] In this embodiment, an anti-skid coating is fixedly provided on the outer side of the transmission wheel 12. The anti-skid coating provided on the transmission wheel 12 ensures that the transmission wheel 12 can normally drive the circuit board to move.

[0037] In this embodiment, limiting rings 27 fixedly connected to the rotating rod 25 are provided on both sides of the transmission gear 26. A pair of limiting plates 28 are fixedly provided on the upper end of the motor base 21. The upper ends of the limiting plates 28 have slots for inserting into the limiting rings 27. The limiting plates 28 and the limiting rings 27 are engaged. Since the rotating rod 25 may deviate after adjusting the distance between the connecting plates 2, causing the intermittent gear 23 to be unable to engage with the driven gear, in this application, the limiting rings 27 and the limiting plates 28 at both ends are engaged. Since the limiting plates 28 are fixed, the limiting rings 27 are also prevented from moving, thereby ensuring that the position of the rotating rod 25 remains unchanged.

[0038] In this embodiment, the recycling structure includes a recycling bin 41 fixedly connected to the base 3 and an inclined plate 4. The inclined plate 4 is fixedly connected to the recycling bin 41 and tilted upward against the L-shaped bracket 1. The arrangement of the recycling bin 41 and the inclined plate 4 ensures that the processed circuit boards are collected together. The L-shaped bracket 1 is made of carbon steel, ensuring its sturdiness.
