[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are some embodiments of the present invention, but not all embodiments.

The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0023] like Figures 1 to 7 As shown, the present invention provides a stamping and forming apparatus for copper core processing, comprising: a machine base 1; a protective cover 2 fixedly installed on the machine base 1; a loading and unloading mechanism for automatically loading and unloading materials during copper core processing; a stamping mechanism for stamping copper core plates; and a pretreatment mechanism for pre-processing copper core plates.

[0024] The loading and unloading mechanism includes: conveyor belt 3, conveyor belt 7, mounting frame 4, and mounting frame 8, all fixedly installed on the machine base 1; linear module 5, fixedly installed on mounting frame 4; robotic arm 6, fixedly installed on linear module 5; linear module 9, fixedly installed on mounting frame 8; robotic arm 10, fixedly installed on linear module 5; turntable 11, rotatably installed on the machine base 1; positioning mold 12, fixedly installed on turntable 11; and a power source 13 that drives the turntable 11 to rotate, the power source 13 being fixedly installed inside the machine base 1.

[0025] The copper core board to be processed is placed on conveyor belt 3. Then, the conveyor belt 3 is started to move the copper core board to the robot arm 6. The robot arm 6 is then started to grab the copper core board and moves it by starting the linear module 5, thereby moving the copper core board above the positioning mold 12. Then, the robot arm 6 is started to place the copper core board in the positioning mold 12.

[0026] After the copper core board is placed in the positioning mold 12, the power source 13 is started to drive the turntable 11 to rotate. The turntable 11 drives the positioning mold 12 to rotate, and the positioning mold 12 drives the copper core board to rotate. The copper core board first rotates to the pre-processing mechanism for pre-processing. After the copper core board is pre-processed, it rotates to the stamping mechanism for stamping under the drive of the turntable 11. After stamping is completed, the turntable 11 drives the stamped copper core to rotate out from the stamping mechanism.

[0027] At this time, the linear module 29 is activated to move the robotic arm 210 to the stamped copper core. The robotic arm 210 is then activated to pick up the copper core and moves to the conveyor belt 27 by the linear module 29. The robotic arm 210 places the copper core on the conveyor belt 27 and then the conveyor belt 27 is activated to unload the copper core.

[0028] In this invention, a plurality of positioning molds 12 are provided, and the plurality of positioning molds 12 are evenly distributed along the circumference of the turntable 11. Specifically, for example, four positioning molds 12 are provided. In the initial state, the four positioning molds 12 are respectively located at the feeding point, the pre-processing mechanism, the stamping mechanism, and the unloading point.

[0029] The copper core board to be processed is placed in the positioning mold 12 at the loading point. At this time, the turntable 11 drives the positioning mold 12 at the loading point to move to the pre-processing mechanism for pre-processing. The positioning mold 12 at the pre-processing mechanism drives the pre-processed copper core board to the stamping mechanism. The positioning mold 12 at the stamping mechanism drives the stamped copper core to the unloading point. The positioning mold 12 at the unloading point moves to the loading point for loading. The turntable 11 rotates 90 degrees each time and repeats this process.

[0030] As can be seen from the above, in this invention, the loading and unloading mechanism enables continuous automatic loading and unloading of copper core boards without the need for manual loading and unloading, saving time and effort, increasing work efficiency, and ensuring high safety.

[0031] It should be noted that the power source 13 is preferably an electric motor; the conveyor belt, robotic arm, and linear module used in this invention are all common equipment on the market.

[0032] The stamping mechanism includes: a fixed frame 14 fixedly installed on the machine base 1; a support frame 15 fixedly installed on the fixed frame 14; a movable frame 17 slidably installed on the fixed frame 14; a second power source 16 for moving the movable frame 17, the second power source 16 being fixedly installed on the support frame 15; and a stamping head 18 fixedly installed on the movable frame 17.

[0033] When the positioning mold 12 moves the pre-treated copper core plate to the stamping mechanism, the second power source 16 is activated to move the movable frame 17 downward. The movable frame 17 then moves the stamping head 18 downward, thereby realizing the stamping and forming of the copper core.

[0034] After the copper core is stamped, the second power source 16 drives the movable frame 17 to move upward, and the movable frame 17 drives the stamping head 18 to reset upward.

[0035] The movable frame 17 and the fixed frame 14 work together to guide and limit the stamping head 18, preventing it from shifting when it moves.

[0036] It should be noted that the second power source 16 is preferably a hydraulic cylinder.

[0037] The pretreatment mechanism includes: an air pump 19 fixedly installed on the protective cover 2; an air collection pipe 22 fixedly installed on the machine base 1, with an exhaust valve (not shown) installed on the air collection pipe 22; an air outlet pipe 20 connecting the air outlet end of the air pump 19 and the air outlet pipe 22; a movable rod 24 installed through the air collection pipe 22; a first piston 23 fixedly installed at the end of the movable rod 24; a return spring 25 that drives the first piston 23 to reset; a nozzle 27; an air guide pipe 26 connecting the nozzle 27 and the air collection pipe 22, with a pressure valve installed on the air guide pipe 26; the first piston 23 is slidably installed inside the air collection pipe 22, and one end of the return spring 25 is fixedly connected to the first piston 23, and the other end of the return spring 25 is fixedly connected to the inner wall of the air collection pipe 22.

[0038] When the positioning mold 12 moves the copper core plate to the pretreatment mechanism, the air pump 19 is started. The air pump 19 delivers high-pressure gas to the gas collection pipe 22 through the air outlet pipe 20. As the air pressure in the gas collection pipe 22 gradually increases, it can drive the first piston 23 to move. The first piston 23 drives the movable rod 24 to move and drives the return spring 25 to compress.

[0039] The turntable 11 has a number of blind holes 47, and the number of blind holes 47 are evenly distributed along the circumference of the turntable 11. The number and position of the blind holes 47 are matched with the positioning mold 12.

[0040] During the copper core board pretreatment process, the stamping mechanism stamps the pretreated copper core board. At this time, the movable rod 24 moves and inserts into the adjacent blind hole 47, thereby fixing the turntable 11 and ensuring the stability of the position of the copper core board during the stamping process. This prevents the turntable 11 from rotating due to external force or vibration during the stamping process, which would cause the position of the copper core board to shift and affect the stamping quality.

[0041] When the movable rod 24 is inserted into the adjacent blind hole 47, the first piston 23 stops moving. At this time, when the pressure in the gas collecting pipe 22 increases to a certain value, the pressure valve opens, and the gas enters the nozzle 27 through the gas guide pipe 26. The gas is then sprayed onto the surface of the copper core board through the nozzle 27, which can remove dust from the copper core board. This prevents dust from adhering to the surface of the copper core board during stamping, causing defects such as scratches and cracks, which would lead to a decrease in the surface quality of the copper core board and may also cause problems with the dimensional accuracy deviation of the stamped parts.

[0042] After the pretreatment is completed, the air pump 19 stops running. At this time, the exhaust valve is opened to discharge the gas in the gas collection pipe 22. At the same time, the first piston 23 is reset under the elastic force of the return spring 25, and the movable rod 24 is separated from the blind hole 47, thereby releasing the fixation of the turntable 11.

[0043] The pretreatment mechanism also includes: a swing assembly that drives the nozzle 27 to swing; the swing assembly includes: a bladder 28 fixedly installed between the movable frame 17 and the fixed frame 14; a fixed rod 35 fixedly installed on the machine base 1; a first mounting seat 36, a second mounting seat 37, and a third mounting seat 38 fixedly installed on the fixed rod 35; an air collecting cylinder 30 fixedly installed on the first mounting seat 36; a connecting pipe 29 connecting the air collecting cylinder 30 and the bladder 28; a connecting rod 32 installed through the air collecting cylinder 30; and a second piston 31 fixedly installed at one end of the connecting rod 32; A rack 33 is fixedly installed at the other end of the linkage rod 32; a linkage spring 48 drives the second piston 31 to reset; a gear 34 is rotatably installed on the second mounting base 37, and the gear 34 meshes with the rack 33; a linkage plate 39 is coaxially connected to the gear 34; a movable plate 40 is rotatably installed on the linkage plate 39; a sliding rod 41 is fixedly installed on the movable plate 40; a nozzle 27 is fixedly installed at the end of the sliding rod 41; one end of the linkage spring 48 is fixedly connected to the second piston 31, and the other end of the linkage spring 48 is fixedly connected to the inner wall of the air collecting cylinder 30.

[0044] During the copper core board pretreatment process, the stamping mechanism stamps the pretreated copper core board. At this time, the second power source 16 drives the movable frame 17 to move downward and compresses the bladder 28, so that the gas in the bladder 28 enters the gas collecting cylinder 30 through the connecting pipe 29. The increased gas pressure in the gas collecting cylinder 30 drives the second piston 31 to move downward. The second piston 31 drives the connecting rod 32 to move downward and compresses the connecting spring 48.

[0045] When the linkage rod 32 moves downward, it drives the rack 33 to move downward, thereby driving the gear 34 to rotate. The gear 34 drives the linkage plate 39 to rotate around the circumference of the gear 34. The linkage plate 39 drives the movable plate 40 to rotate around the circumference of the gear 34. The movable plate 40 drives the sliding rod 41 to rotate around the circumference of the gear 34. The sliding rod 41 drives the nozzle 27 to rotate around the circumference of the gear 34, thereby expanding the spray range of the nozzle 27 and improving the cleaning effect on the copper core board.

[0046] After the stamping is completed, the movable frame 17 moves upward and drives the bladder 28 to return to its original position, so that the gas in the gas collecting cylinder 30 can be drawn into the bladder 28. At this time, the second piston 31 is reset by the elastic force of the linkage spring 48, which in turn drives the nozzle 27 to reset, preparing it for subsequent use.

[0047] The swing assembly also includes: a fixed plate 42 fixedly mounted on the third mounting base 38; a guide groove 43 formed on the fixed plate 42; and a sliding rod 41 slidably mounted in the guide groove 43. The guide groove 43 is an arc-shaped groove with uniform waveform, and the sliding rod 41 is slidably mounted in the guide groove 43.

[0048] When the nozzle 27 rotates circumferentially along the gear 34, the sliding rod 41 moves along the path of the guide groove 43. At this time, the sliding rod 41 drives the movable plate 40 to move. Under the guidance of the guide groove 43, the movable plate 40 swings back and forth at the point of rotation of the connecting plate 39, so that the nozzle 27 swings back and forth while rotating circumferentially along the gear 34, further expanding the spray range of the nozzle 27, realizing comprehensive cleaning of the stamped surface of the copper core plate, and greatly improving the cleaning effect of the copper core plate.

[0049] The pretreatment mechanism also includes: a treatment box 44 fixedly installed on the mounting cover; an air suction pipe 45 connected to the treatment box 44; an air suction hood 46 connected to the air suction pipe 45; and an air inlet pipe 21 connecting the treatment box 44 and the air inlet end of the air pump 19.

[0050] When the air pump 19 is started, it draws the gas out of the processing box 44 through the air inlet pipe 21. At this time, a negative pressure is formed in the processing box 44, which causes the suction hood 46 to generate suction. At this time, the outside air enters the processing box 44 through the suction hood 46 and the suction pipe 45 in sequence.

[0051] During this process, the dust blown off by the nozzle 27 can enter the suction hood 46 with the airflow and enter the processing box 44 through the suction pipe 45. The processing box 44 is equipped with a filter screen (not shown) to filter the dust. The dust is retained in the processing box 44, and the filtered air is sucked out by the air pump 19 and then sprayed onto the surface of the copper core board through the nozzle 27.

[0052] Since the nozzle 27 sprays out clean gas, it avoids secondary contamination of the copper core board by dust and improves the cleaning effect of the copper core board.

[0053] Furthermore, by blowing and sucking, the dust on the surface of the copper core board is cleaned and collected at the same time, avoiding the problem of dust floating in the air and re-adhering to the surface of the copper core board, thus further improving the cleaning effect of the copper core board.

[0054] It should be noted that a sealed door (not shown) is installed on the side wall of the treatment box 44. When the dust collected in the treatment box 44 is to be treated, the sealed door can be opened to facilitate the treatment of the dust and the maintenance of the filter.

[0055] In this invention, the pre-treatment mechanism enables comprehensive cleaning of the stamped surface of the copper core board, greatly improving the cleaning effect. Furthermore, by using a blowing and suction method, the dust on the surface of the copper core board is cleaned and collected simultaneously, preventing the dust from being dispersed in the air and re-adhering to the surface of the copper core board, thus further improving the cleaning effect.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.
