Description

Technical Field

[0001] This utility model relates to an aluminum substrate tearing edge, and more particularly to an automatic aluminum substrate tearing edge line. Background Technology

[0002] Due to increased customer demands for high-performance aluminum substrates with improved electrical withstand voltage, a withstand voltage test of 2000V-6000V is required to ensure product reliability. Currently, the entire CCL industry uses manual methods to meet this requirement. A simple tool consisting of a pressure plate and pliers is used to peel off the copper edges of the aluminum substrate, exposing approximately 10mm of insulation on all four sides before the withstand voltage test. This method has the following disadvantages: 1. Low output: A team of two working 12-hour shifts produces only about 400 sheets. 2. High workload for peeling workers: They typically experience arm fatigue and need rest after peeling only 30-50 sheets. This high workload makes it difficult to retain skilled workers, further reducing production efficiency and increasing costs. 3. Lack of automation: It does not allow for control over the quality and efficiency of the aluminum substrate peeling process. Utility Model Content

[0034] The servo transplanter 6 includes two first supports 34 located outside the positioning mechanism 2 and the discharge mechanism, and a fourth slide rail 35 located at the top between the two first supports 34. The bottom of the fourth slide rail 35 is provided with a fourth slider that can move along the fourth slide rail 35 at the positioning mechanism 2, the warp tearing mechanism 3, the weft tearing mechanism 4 and the discharge mechanism. The fourth slider moves back and forth between the original process position and the next process position. Each fourth slider has a material picking part rotatably provided at its bottom. The material picking part includes a downward-facing telescopic fourth cylinder 36 rotatably provided at the bottom of the fourth slider. The bottom of the telescopic end of the fourth cylinder 36 is provided with a fixing plate 38 with a vacuum suction cup 37.

[0035] The positioning mechanism 2 includes a positioning platform 39 mounted on the frame 1, a Y-axis servo-driven clamping mechanism 40 mounted on the frame 1 above the positioning platform 39, two sets of X-axis servo-driven clamping mechanisms 41 mounted on the frame 1 above the positioning platform 39, and a positioning laser sensor.

[0036] The Y-axis servo drive clamping mechanism 40 includes a Y-axis servo module 42 mounted on the frame 1 and a second base plate 43 slidably mounted on the Y-axis servo module 42. A first positioning clamp is provided on each of the top two sides of the second base plate 43. The first positioning clamp includes a second connecting plate 44 vertically mounted on the second base plate 43, a first parallel finger cylinder 45 vertically mounted on the outer wall of the second connecting plate 44, and a first chuck 46 mounted on the first finger cylinder. The first chuck 46 is a circular roller and is oriented forward.

[0037] The X-axis servo drive clamping mechanism 41 includes an X-axis servo module 47 mounted on the frame 1 and a third base plate 48 slidably mounted on the X-axis servo module 47. A second positioning clamp is provided on the top of the third base plate 48. The second positioning clamp includes a third connecting plate 49 vertically mounted on the third base plate 48, a second parallel finger cylinder 50 vertically mounted on the side wall of the third connecting plate 49, and a second chuck 51 mounted on the second finger cylinder. The second chuck 51 is a circular roller and faces to the right.

[0038] The horizontal servo lead screw drive mechanism 10 includes a first lead screw 52, ​​a second lead screw 53, and a rotating shaft 55 connected to a first servo motor drive 54. The bottom of the first base plate 11 of the tearing edge brackets on both sides is slidably connected to the corresponding first lead screw 52 or second lead screw 53. The two ends of the rotating shaft 55 are respectively connected to the corresponding first lead screw 52 and second lead screw 53 through a second coupling 56. The thread of the first lead screw 52 is opposite to the thread of the second lead screw 53.

[0039] The outer side of the edge discharge port 14 of the first base plate 11 is provided with a splash guard 57 to prevent copper shavings generated during the tearing process from flying out.

[0040] The lower part of the frame 1 is provided with a waste edge material collection box 58 below the edge material outlet 14 of the first base plate 11, which facilitates the collection of waste copper edges.

[0041] In use, the first step is to set the various operating parameters of the aluminum substrate on the touch screen and transmit them to the controller. After starting, the servo transfer machine picks up the aluminum substrate one by one from the pallet and sends it to the positioning table 39 to complete the feeding.

[0042] The second step involves precisely positioning the aluminum substrate on the positioning table 39 after feeding. The second chucks 51 of the two sets of X-axis servo-driven clamping mechanisms 40 clamp the two ends of the aluminum substrate in the X-axis direction for correction and movement. The positioning is then confirmed by a laser sensor, thus completing the correction and positioning in the X-axis direction. After the X-axis positioning is completed, the first chucks 46 of the Y-axis servo-driven clamping mechanism 41 clamp the two ends of the aluminum substrate in the Y-axis direction for translation. The positioning in the Y-axis direction is then confirmed by a laser sensor, thus completing the precise positioning of the aluminum substrate.

[0043] The third step involves the servo transfer machine precisely picking up the precisely positioned aluminum substrate and transferring it onto the tearing table 7 of the warp tearing machine. The first cylinder 15 is activated and presses down, causing the aluminum substrate to be pressed against the pressure plates 17 with blades 16 on both sides. Simultaneously, the servo lifting mechanism 19 lowers the tearing clamps 18, and the horizontal servo screw drive mechanism 10 moves the tearing supports 8 on both sides inwards. After the two sets of tearing clamps 18 on the same side move to the set position, the third cylinder 29 lowers, causing the upper clamping plate 31 and lower clamping plate 30 to close and clamp the copper edge of the aluminum substrate. After all four clamps have secured the copper edge, the servo lifting mechanism 19 is activated to rise with the set parameters, while the horizontal servo screw drive mechanism 10 moves horizontally towards the center with the set parameters until the copper edge is torn off the aluminum substrate. After the copper edge is torn off, the servo lifting mechanism 19 descends, and the third cylinder 29 rises to separate the upper clamping plate 31 from the lower clamping plate 30, dropping the copper edge waste from the edge discharge port 14 into the waste edge collection box 58, thus completing the automatic tearing of the radial copper edge of the aluminum substrate. After the tearing is completed, the servo transfer machine picks up the substrate, and the first cylinder 15 rises to the position.

[0044] In the fourth step, the servo transfer machine rotates the aluminum substrate with the copper edge torn off by 90 degrees and sends it to the tearing table 7 of the weft tearing machine; the weft tearing machine repeats the automatic tearing steps of the third step to complete the automatic tearing of the weft copper edge of the aluminum substrate.

[0045] The fifth step involves the aluminum substrate with the woven copper edge automatically peeled off being picked up by a servo transfer machine and moved to the discharge conveyor 5. After surface dust collection is completed on the discharge conveyor 5, it is transported to the electrical testing line for automatic electrical testing.

[0046] The beneficial effects of the above-mentioned structure of this utility model are as follows: The automatic edge-tearing line for aluminum substrates provided by this utility model automatically tears off the copper edges on the aluminum substrate through the designed edge-tearing mechanism, realizing automatic edge tearing. The entire automatic edge-tearing line only requires 2 operators to complete, saving manpower and production costs, reducing working space, reducing a lot of handling waste, improving production efficiency and product quality, realizing automated and visualized operation, facilitating quality and cost management, and can be integrated with electrical testing to form a production line operation, facilitating automated production management and improving the stability of edge-tearing quality.

[0047] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
