Description

Technical Field

[0001] This invention relates to the field of automated sheet metal processing technology, specifically to an automatic sheet metal stacking and receiving machine. Background Technology

[0002] Circuit boards are insulating and conductive composite materials used in the electronics industry. The stacking and receiving of circuit boards refers to the process of transporting, positioning and aligning the finished PCB boards or copper-clad boards in sequence through an automated mechanism, and stacking them neatly on a support platform to form a stack, thereby achieving continuous, orderly and damage-free collection and temporary storage of finished products.

[0003] In the current process of stacking and collecting circuit board materials, circuit boards are often placed directly in layers without effective isolation and protection, which can easily cause scratches, adhesion and static damage to the board surface. At the same time, there is an impact when the materials are dropped, and thin boards are easily bent and deformed. Moreover, the stacking positioning accuracy is poor, and boards are prone to misalignment and skew, which affects the neatness of the stack. In addition, the inter-board film or paper separation relies on manual assistance, resulting in low automation and collection efficiency. Summary of the Invention

Detailed Implementation

[0018] like Figures 1-4 As shown, the automatic stacking and receiving machine for board materials according to the present invention is applied to the stacking and receiving of circuit board materials. It includes a board material conveying assembly 10, a stacking execution assembly 20 and a separator film cutting assembly 30. The board material conveying assembly 10 extends in the horizontal direction, and one end of the board material conveying assembly 10 is the feeding end and the other end is the receiving end. The release film cutting assembly is positioned above the sheet material conveying assembly 10 and close to the feed end, and is used to cut the release film adapted to the sheet material 40. The stacking execution component 20 is disposed on one side of the plate conveying component 10. The plate 40 and the separator are conveyed alternately from the feeding end to the receiving end on the plate conveying component 10, and the plate 40 and the separator are stacked alternately by the stacking execution component 20. By alternately conveying and stacking the board material 40 and the separator film on the board material conveying assembly 10, the film is stacked layer by layer, avoiding direct contact and friction between the circuit boards, effectively preventing scratches, solder mask wear, electrostatic adhesion, and oxidation of the circuit board surface. By setting the separator film cutting assembly 30 above the feeding end, the separator film that matches the size of the circuit board can be automatically cut, eliminating the need for manual film cutting and laying, greatly reducing manual intervention and improving automation and material collection efficiency. By using the stacking execution assembly 20 to stack the board material 40, the impact caused by direct material dropping and stacking is avoided, which can cause the board material 40 to bend and deform. The integrated conveying, film cutting, and alternating stacking functions are compact in structure and layout, eliminating the need for multi-station transfer, adapting to the online material collection of the circuit board production line, and having strong versatility, it can adapt to the stacking and material collection needs of different specifications of board material 40.

[0019] Furthermore, in this embodiment, the stacking execution component 20 includes a first support 201, a gripping mechanism 202, and a first adjustment mechanism 203 and a second adjustment mechanism 204 connected to each other. The first adjustment mechanism 203 is slidably connected to the first support 201, and the first adjustment mechanism 203 slides upward or downward on the first support 201 in the vertical direction. The first support 201 is provided with two first slide rails 2011, which are vertically arranged on the first support 201 in the vertical direction. The first adjustment mechanism 203 includes a first connecting plate and a first slider connected to each other. The two first sliders are slidably connected to the two first slide rails 2011 respectively, so that the first adjustment mechanism 203 slides upward or downward in the vertical direction. The second adjustment mechanism 204 includes a second connecting plate and a second slider connected together. The top of the second connecting plate is fixedly connected to the bottom of the first connecting plate, so that the second adjustment mechanism 204 slides upward or downward in the vertical direction along with the first adjustment mechanism 203. The gripping mechanism 202 is slidably connected to the second adjusting mechanism 204, and the gripping mechanism 202 slides to the left or right in the horizontal direction on the second adjusting mechanism 204; The gripping mechanism 202 is connected to a second slide rail 2023, which extends horizontally and is slidably connected to a second slider, so that the gripping mechanism 202 can slide left or right on the second adjustment mechanism 204 via the second slide rail 2023.

[0020] Furthermore, in this embodiment, the gripping mechanism 202 includes a positioning plate 2021 and a plurality of suction cups 2022 disposed on the lower surface of the positioning plate 2021. The plurality of suction cups 2022 are evenly arranged on the lower surface of the positioning plate 2021, and the suction cups 2022 are used to grip the plate 40 and the isolation film. In this embodiment, two rows of suction cups 2022 are provided under the positioning plate 2021, which are... Figure 2 As shown, the suction cup 2021 picks up the board 40 or the release film and places it in the stack position. The suction cup 2021 picks up the board 40 and the release film alternately in sequence and places them stacked together alternately. The suction cup 2022 can be a vacuum suction cup so that there is no hard contact when picking up the board 40, thus avoiding damage to the board 40.

[0021] Furthermore, in this embodiment, the isolation membrane cutting assembly 30 includes a second support 301, and a film supply mechanism 302 and a cutting mechanism 303 disposed on the second support 301. The film supply mechanism 302 and the cutting mechanism 303 are both located above the sheet material conveying assembly 10, and the cutting mechanism 303 is located above the film supply mechanism 302. The second support 301 extends upward in the vertical direction and is higher than the sheet material conveying assembly 10.

[0022] Furthermore, in this embodiment, the film supply mechanism 302 includes a release film sleeve 3021, a winding rod 3022, and a first transmission pulley 3023. The release film sleeve 3021 and the winding rod 3022 are respectively rotatably connected to the two ends of the second support 301 in the horizontal direction. The release film sleeve 3021 has an uncut roll of release film. The separator can be an antistatic PE film (polyethylene protective film), which has a smooth surface, good toughness, dustproof and scratch-resistant properties, and can prevent direct friction between the surfaces of two boards. In other optional embodiments, the separator can be an antistatic separator paper, which is soft, has its own antistatic effect, will not cause static electricity to break down the circuit board lines, absorbs water and prevents moisture from oxidizing the circuit board, and is soft in texture so as not to scratch the green solder mask and solder pads on the board surface. The end of the release film of the release film sleeve 3021 is wound around to the winding rod 3022 and connected to the winding rod 3022. Both ends of the winding rod 3022 are connected to the first transmission pulleys 3023 so as to drive the winding rod 3022 to rotate. The end of the release film of the release film sleeve 3021 is connected to the winding rod 3022 so that when the winding rod 3022 rotates, it drives the release film sleeve 3021 to rotate, thereby winding the release film from the release film sleeve 3021 to the winding rod 3022. In this embodiment, the release film located between the release film sleeve 3021 and the winding rod 3022 is cut by the cutting mechanism 303 to be adapted to the plate 40, and the remaining release film after cutting is wound onto the winding rod 3022. One end of the first transmission pulley 3023 is connected to one end of the winding rod 3022, and the other end is connected to the gear and rack mechanism. The first transmission pulley 3023 rotates synchronously with the gear and rack mechanism, that is, the winding rod 3022 also rotates with the first transmission pulley 3023. The first transmission pulleys 3023 connected to both ends of the winding rod 3022 are the same and rotate at the same speed.

[0023] Furthermore, in this embodiment, the cutting mechanism 303 includes a cutting frame 3031, a push plate 3032, a top plate 3033, a cutting blade, a second transmission pulley 3034, and multiple connecting rods 3035. The cutting frame 3031 is connected to the middle area of ​​the top of the second support 301. The push plate 3032 is disposed below the cutting frame 3031. One end of each connecting rod 3035 is connected to the push plate 3032. The connecting rod 3035 passes vertically upward through the cutting frame 3031 and is slidably connected to the cutting frame 3031. The other end of each connecting rod 3035 is connected to the top plate 3033. Four connecting rods 3035 are selected and located at the four corners of the push plate 3032. One end of the connecting rod 3035 is fixedly connected to the upper surface of the push plate 3032, and the other end is fixedly connected to the top plate 3033. The connecting rod 3035 passes through the cutting frame 3031, that is, the push plate 3032 is located below the cutting frame 3031, and the top plate 3033 is located above the cutting frame 3031. The connecting rod 3035 is slidably connected to the cutting frame 3031, so that the push plate 3032 and the top plate 3033 can move upward or downward in the vertical direction. The cutting blade is connected to the lower end of the push plate 3032, and the second transmission pulley 3034 is located below the top plate 3033; The size of the cutting blade is the same as the size of the plate 40. In other alternative embodiments, the size of the cutting blade can be adjusted appropriately, for example, the size of the cutting blade is larger than the size of the plate 40, so that the cut isolation film can completely cover the plate 40.

[0024] Furthermore, in this embodiment, the cutting frame 3031 is provided with a lead screw 3036 adapted to the second transmission pulley 3034. The lead screw 3036 extends upward in the vertical direction and passes through the top plate 3033. The second transmission pulley 3034 is rotatably connected to the lead screw 3036. Through the transmission between the second transmission pulley 3034 and the lead screw 3036, the push plate 3032 and the top plate 3033 are driven to move upward or downward in the vertical direction. Two lead screws 3036 are selected. One end of the lead screw 3036 is fixedly connected to the cutting frame 3031, and the other end extends vertically upward and passes through the top plate 3033. The second transmission pulley 3034 includes a transmission belt and three rotating wheels. Each lead screw 3036 is connected to a rotating wheel, one of which is connected to the drive assembly. The transmission belt is wound around the three rotating wheels to form a triangular structure. The second transmission pulley 3034 rotates, causing it to move vertically upward or downward on the lead screw 3036, thereby driving the push plate 3032 and the top plate 3033 to move vertically upward or downward. Since the push plate 3032 has a cutting blade below it, it contacts the isolation membrane and cuts it when moving downward. After each cut, the cut release film will fall onto the board conveying assembly 10 for conveying. That is, it will be cut once every time a board 40 passes by, so that the board 40 and the release film can be conveyed alternately on the board conveying assembly 10. After each cut, the winding rod 3022 will rotate to wind the remaining release film after cutting onto the winding rod 3022, and the uncut release film will be conveyed to the bottom of the push plate 3032 for the next cut. The sheet material 40 and the cut release film are conveyed alternately in the sheet material conveying assembly 10. The suction cup 2021 of the gripping mechanism 202 picks up the sheet material 40, then picks up the release film and places it on the previous sheet material 40, and then picks up the next sheet material 40 and places it on the previous release film. This process is repeated until the material is stacked to a suitable height, and then it is conveyed to the receiving end for receiving.

[0025] Furthermore, in this embodiment, the automatic stacking and receiving machine for the sheet metal also includes a control component, and the sheet metal conveying component 10, the stacking execution component 20 and the isolation membrane cutting component 30 are all signal-connected to the control component; The control component can be a PLC (Programmable Logic Controller), which controls the board conveying component 10, the stacking execution component 20 and the isolation membrane cutting component 30. It has the advantages of strong anti-interference, simple wiring and stable durability. In other optional embodiments, a microcontroller can be selected as the control component. The appropriate control component can be selected according to the actual situation.

[0026] Furthermore, in this embodiment, the sheet material conveying assembly 10 includes a first conveying mechanism 101 and a second conveying mechanism 102 that are adjacent to each other. The first conveying mechanism 101 and the second conveying mechanism 102 are arranged sequentially from the feeding end to the receiving end in the horizontal direction. The first conveying mechanism 101 is used for conveying unstacked sheet materials 40 and the release film, and the second conveying mechanism 102 is used for conveying stacked sheet materials 40 and the release film. This allows for separate control of the speeds of the two, thereby improving the stacking and receiving processes. Both the first conveying mechanism 101 and the second conveying mechanism 102 are belt driven.

[0027] Furthermore, in this embodiment, the automatic stacking and receiving machine for the sheet metal also includes a drive assembly and a power supply, which are electrically connected. The sheet metal conveying assembly 10, the stacking execution assembly 20, and the isolation membrane cutting assembly 30 are all electrically connected to the drive assembly. The drive assembly includes a first motor 50, a second motor 60, a third motor 70, a first cylinder mechanism 80, and a second cylinder mechanism 90; the drive end of the first motor 50 is connected to the first adjustment mechanism 203 to drive the first adjustment mechanism 203 to slide upward or downward in the vertical direction. The drive end of the second motor 60 is connected to the second slide rail 2023 to drive the second slide rail 2023 to slide left or right along the second slider in the horizontal direction. The third motor 70 is mounted on the top plate 3033, and the output end of the third motor 70 is connected to one of the rotating wheels of the second transmission pulley 3034 to drive the second transmission pulley 3034 to rotate. The first cylinder mechanism 80 is mounted on the positioning plate 2021 and connected to the suction cup 2022 to drive the suction cup 2022 to pick up the plate 40 or the isolation film. The second cylinder mechanism 90 is mounted on the second support 301 and connected to the gear and rack mechanism to drive the gear and rack mechanism to move, thereby driving the rotation of the first transmission pulley 3023, which in turn drives the rotation of the winding rod 3022.
