Description

Technical Field

[0001] This utility model belongs to the technical field of copper plate processing equipment, and in particular relates to an automatic production line for cutting, grinding, and rounding corners. Background Technology

[0002] Copper plates are widely used in the production of electronic circuit board substrates, hardware stamping parts, architectural decorative panels and other products due to their excellent electrical conductivity, thermal conductivity and ductility.

[0003] In the copper plate processing industry, blanking, edge grinding, and rounding of corners are the core processes in copper plate forming and processing, directly affecting the dimensional accuracy, appearance quality, and subsequent assembly efficiency of copper plate products. In traditional copper plate processing, the above three core processes, as well as subsequent auxiliary processes such as coating, drilling, and marking, all rely on independent equipment. There is a lack of coordination between these machines, resulting in low processing efficiency.

[0004] Specifically, the traditional processing flow involves the following steps: First, operators need to transport the copper plate raw material to be processed to independent cutting equipment (such as a table saw or a panel saw) for dimensional cutting. After cutting, the cut copper plate needs to be transferred manually or by a simple robotic arm to a separate edge grinding equipment (such as a manual sander or a semi-automatic edge grinding machine) to remove burrs and smooth the long and short edges. After the edge grinding process is completed, the copper plate is transferred again to an independent stacking and rounding machine to round the edges and corners of the copper plate to avoid scratches during use. Subsequent processes such as drilling holes, attaching pins, applying adhesive, and laser marking also require repeating the above "processing-transfer-reprocessing" process. Each process requires separate investment of manpower or equipment resources for transfer, resulting in cumbersome transfer steps and low work efficiency. Utility Model Content

[0058] In another embodiment of this utility model, both the large cutting machine 2 and the small cutting machine 5 are provided with an edge material outlet 30 at one end.

[0059] In another embodiment of this utility model, two of each of the following are provided: long-side corner conveyor 7, centering conveyor 9, short-side grinding machine 10, rotary centering machine 11, long-side grinding machine 12, stacking corner rounding machine 13, servo longitudinal take-up and put-out plate machine 14, and short-side corner conveyor 15, which are arranged in parallel and symmetrically.

[0060] In another embodiment of this utility model, an emergency passage 40 is provided between the corner rounding machine 13 and the servo longitudinal take-up and take-down machine 14.

[0061] In another embodiment of this utility model, there are two transfer feeders 16, which are arranged in parallel.

[0062] In another embodiment of this utility model, there are two discharge and plate-receiving machines 23, which are arranged in parallel.

[0063] In another embodiment of this utility model, the short edge grinding machine 10, the long edge grinding machine 12, the stacking corner rounding machine 13, and the drilling and pinning machine 19 are all equipped with dust suction pipes 50.

[0064] The automatic production line for cutting, grinding, and rounding corners provided in this application operates as follows:

[0065] (1) Feeding and cutting process:

[0066] The operator places the copper plate raw material to be processed in the raw material placement area of ​​the feeding gantry transfer robot 1. After starting the automatic line, the feeding gantry transfer robot 1 uses the suction cup assembly to pick up a single copper plate according to the preset program and transfers it to the feeding platform of the large cutting machine 2.

[0067] The positioning sensor of the large cutting machine 2 detects the position of the copper plate, and the servo motor drives the cutting saw blade to cut according to the preset size (such as cutting 1220mm×2440mm raw material into 600mm×2400mm semi-finished product). The scrap generated during the cutting process is transported to the external scrap recycling box through the scrap outlet 30.

[0068] The cut semi-finished copper plate is moved from the discharge conveyor belt of the large cutting machine 2 to the temporary storage platform 3. After the photoelectric sensor of the temporary storage platform 3 detects that the copper plate is in place, it sends a signal to the rotating gantry transfer robot 4.

[0069] After receiving the signal, the rotating gantry transfer robot 4 grabs the semi-finished copper plate on the temporary storage platform 3 and transfers the copper plate to the feeding platform of the small cutting machine 5 according to the feeding direction requirements of the small cutting machine 5 (if the feeding direction of the small cutting machine 5 is perpendicular to the output direction of the large cutting machine 2, the robot rotates 90°).

[0070] The small cutting machine 5 performs secondary cutting according to the preset size (such as cutting a 600mm×2400mm semi-finished product into a 600mm×800mm finished substrate). The cut edge material is also recycled through the edge material outlet 30. The finished substrate material after cutting is conveyed to the two-way splitter 6.

[0071] (2) Separation and edge grinding / rounding process:

[0072] After receiving the finished substrate, the bidirectional PCB separator 6 distributes the substrate evenly to the long-side corner conveyors 7 on both sides according to the load of the two grinding and rounding channels (by detecting the amount of material in the channel through sensors). If one channel is idle, the substrate is preferentially distributed to the idle channel.

[0073] After the long-side corner conveyor 7 transports the substrate to the 90° corner position, the servo transverse plate take-up machine 8 temporarily stores the substrate or directly transports it to the center conveyor 9 according to the processing rhythm of the subsequent center conveyor 9 (if the center conveyor 9 is processing the previous substrate, the servo transverse plate take-up machine 8 will temporarily store the substrate).

[0074] The central conveyor 9 precisely positions the substrate through the positioning baffles on both sides and conveys it to the short edge grinding machine 10;

[0075] The grinding wheel of the short edge grinding machine 10 grinds the short edge (600mm edge) of the substrate to remove cutting burrs. The copper shavings generated during the grinding process are sucked into the external dust collection system through the dust suction pipe 50.

[0076] After the short side is ground, the substrate is conveyed to the rotary centering machine 11. The rotary centering machine 11 rotates the substrate 90° and repositions it according to the feeding direction of the long side grinding machine 12 (the 600mm long side of the substrate needs to be adjusted to the feeding direction). Then it is conveyed to the long side grinding machine 12.

[0077] The grinding wheel of the long edge grinding machine 12 grinds the long edge (800mm edge) of the substrate. The grinding parameters are the same as those of the short edge grinding machine 10. Copper shavings are also collected through the dust suction pipe 50.

[0078] After the long edge is ground, the substrate is conveyed to the stacking corner rounding machine 13. The mechanical claw of the stacking corner rounding machine 13 positions the substrate, and then the corners of the stacked substrate are simultaneously rounded by a corner rounding knife (made of high-speed steel with a cutting radius of R3mm). The copper shavings generated during the processing are collected through the dust suction pipe 50.

[0079] After the rounded corners are processed, the entire stack of substrate is conveyed by the servo longitudinal take-up and take-down board machine 14 to the short side corner conveyor 15. The short side corner conveyor 15 transfers the substrate to the transfer feeder 16 in the transfer transition area (two sets of transfer feeders 16 receive the substrate alternately to avoid material accumulation).

[0080] (3) Subsequent processing and unloading procedures:

[0081] The transfer feeder 16 conveys the entire stack of substrate to the paper pad feeder 17. The paper pad feeder 17 automatically lays paper pads on the upper and lower surfaces of the substrate in a rhythm of "one substrate + one paper pad" (the paper pad is 0.2mm thick to prevent scratches on the substrate surface).

[0082] After the paper pads are laid, the substrate is stacked and conveyed to the positioning stacking machine 18. The positioning stacking machine 18 adjusts the stacked substrate to a neat state through the positioning rod driven by the servo motor, and then conveys it to the drilling and pinning machine 19.

[0083] The drilling and pinning machine 19 drills holes to a depth of 12mm using a 5mm diameter drill bit according to the preset drilling positions (such as the four corners of the substrate, 20mm from the edge). Then, it automatically presses the pin (φ5×15mm) into the drilled hole (the pin protrudes 3mm for subsequent assembly). The copper shavings generated during the drilling process are collected through the dust suction pipe 50.

[0084] After drilling and pinning, the substrate is conveyed to the short-side rubber coating and aluminum sheet mounting machine 20. The machine first wraps PVC strips (18mm wide and 1mm thick) on the short side (600mm side) of the substrate, and then presses aluminum sheets (20mm×18mm, 0.5mm thick, to enhance edge wear resistance) onto the surface of the strip.

[0085] After the short side is coated, the substrate is conveyed to the long side coating machine 21, where the equipment wraps the substrate with PVC strips of the same specification along the long side (800mm side).

[0086] After the coating is completed, the substrate is conveyed to the laser marking and flipping machine 22. The machine first prints product information (such as model, production date, batch number) on the surface of the substrate using a laser marking tool (wavelength 1064nm, marking speed 50mm / s). Then, the flipping mechanism flips the substrate 180° and performs the same marking on the other side (if only single-sided marking is required, the flipping function can be turned off through the program).

[0087] After laser marking is completed, the substrate is conveyed to the unloading and receiving machine 23 in the unloading and receiving area. Two sets of unloading and receiving machines 23 take turns receiving the finished substrate. When the substrate in the receiving machine reaches the preset quantity, the equipment sends a signal to the operator, who then transfers the finished substrate to the finished product warehouse.

[0088] The automatic production line for cutting, grinding, and rounding corners provided in this application adopts an integrated design for the entire process of "feeding-cutting-grinding-rounding-post-processing-discharging". Automated transfer components such as the feeding gantry transfer robot 1 and the rotating gantry transfer robot 4 replace the traditional manual or simple robot for decentralized transfer, realizing seamless connection of materials between each process, eliminating additional transfer steps, and improving work efficiency.

[0089] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
