[0011] 1. Since the frame is arranged on the ground, a workbench is rotatably connected to the frame. A motor is arranged on the frame. The motor rotates the workbench and limits the angle of the workbench to a certain angle. A first feeding device, a second feeding device, a detection station, a third feeding device, a pressing device and a discharging device are sequentially arranged on the frame. The first feeding device first moves the copper sheets to the outlet, and then moves the copper sheets in groups of four to the second feeding device. Subsequently, the second moving device moves the four groups of copper sheets to the clamping members on the workbench. Then the workbench rotates 45°, so that this clamping member is located at the detection station. The detection station detects whether the number of copper sheets meets the standard. If it meets the standard, the workbench continues to rotate 45°. This clamping member is located at the third feeding device. The third feeding device moves the bottom plate to the clamping member and the bottom plate corresponds to the copper sheets at this time. Then the workbench continues to rotate 45°, so that this clamping member is located at the pressing device. There are two groups of pressing devices. The pressing devices fix the copper sheets on the bottom plate. Then this clamping member is moved to the discharging device. The discharging device moves the processed workpieces to the finished product area. A first support member is arranged on the frame. A first pushing member is arranged on the first support member. The first pushing member is a cylinder. The acting end of the first pushing member is provided with a first stamping member. A second support member is arranged on the frame. A second stamping member is slidably connected to the second support member. The second stamping member corresponds to the position of the first stamping member. A first inclined surface is opened at the bottom of the second stamping member. A second pushing member is arranged on the frame. The acting end of the second pushing member is provided with a sliding block. A second inclined surface is opened at the top of the sliding block. The first inclined surface corresponds to the second inclined surface. When the sliding block slides, the first inclined surface and the second inclined surface move relative to each other and the first inclined surface and the second inclined surface always fit together, so that the second stamping member moves up and down. The first stamping member at the first station has a buffering effect and is a pre-pressing station. The first stamping member at the second station is a complete pressing station. A first block is arranged at the acting end of the first support member at the first station. A stamping block is arranged on the first block. A second block is arranged below the first block. A guide rod is arranged on the second block. The guide rod passes through the first block. The second block and the first block move up and down relative to each other. An elastic member is sleeved on the guide rod. One end of the elastic member abuts against the first block, and the other end of the elastic member abuts against the second block. The stamping block passes through the second block. When the second block does not contact the bottom plate, the stamping block does not protrude from the second block. When the second block contacts the bottom plate, the elastic member is compressed and the stamping block gradually moves towards the bottom plate until stamping the bottom plate. At this time, the second block presses the bottom plate to prevent the bottom plate from moving. Thus, the copper sheets are stamped on the bottom plate through two groups of stations and the upper and lower two groups of stamping members have a small force on the workbench.

[0023] The frame 1 is arranged on the ground. A workbench 2 is rotatably connected to the frame 1. A motor is arranged on the frame 1. The motor rotates the workbench 2 and limits the angle of the workbench 2 to a certain angle. A first feeding device 3, a second feeding device 4, an inspection station 5, a third feeding device 6, a pressing device 7 and a discharging device 8 are successively arranged on the frame 1. The first feeding device 3 first moves the copper sheets to the outlet, and then moves the copper sheets four by four to the second feeding device 4. Subsequently, the second moving device moves the four groups of copper sheets to the clamping members 21 on the workbench 2. Subsequently, the workbench 2 rotates 45°, so that the clamping member 21 is located at the inspection station 5. The inspection station 5 detects whether the number of copper sheets meets the standard. If it meets the standard, the workbench 2 continues to rotate 45°. This clamping member 21 is located at the third feeding device 6.

When the sliding block 77 slides, the first inclined surface 761 and the second inclined surface 771 move relative to each other and the first inclined surface 761 and the second inclined surface 771 always fit together, so that the second stamping member 76 moves up and down. The first stamping member 73 at the first station has a buffering effect and is a pre-pressing station. The first stamping member 73 at the second station is a full pressing station. A first block 731 is arranged at the acting end of the first support member 71 at the first station. A stamping block 732 is arranged on the first block 731. A second block 733 is arranged below the first block 731. A guide rod 734 is arranged on the second block 733. The guide rod 734 passes through the first block 731.

One end of the elastic member 735 abuts against the first block 731, and the other end of the elastic member 735 abuts against the second block 733. The stamping block 732 passes through the second block 733. When the second block 733 does not contact the bottom plate, the stamping block 732 does not protrude from the second block 733. When the second block 733 contacts the bottom plate, the elastic member 735 is compressed and at the same time the stamping block 732 gradually moves towards the bottom plate until stamping the bottom plate. At this time, the second block 733 presses the bottom plate to prevent the bottom plate from moving.

[0024] Since the frame 1 is arranged on the ground, the workbench 2 is rotatably connected to the frame 1. There is a motor on the frame 1, and the motor rotates the workbench 2 and limits the angle of the workbench 2 to a certain angle. The first feeding device 3, the second feeding device 4, the detection station 5, the third feeding device 6, the pressing device 7 and the discharging device 8 are successively arranged on the frame 1. The first feeding device 3 first moves the copper sheets to the outlet, and then moves the copper sheets in groups of four to the second feeding device 4. Then the second moving device moves the four groups of copper sheets to the clamping parts 21 on the workbench 2. Then the workbench 2 rotates 45°, so that the clamping part 21 is located at the detection station 5. The detection station 5 detects whether the number of copper sheets meets the standard. If it meets the standard, the workbench 2 continues to rotate 45°, and the clamping part 21 is located at the third feeding device 6. The third feeding device 6 moves the bottom plate to the clamping part 21 and the bottom plate corresponds to the copper sheets at this time. Then the workbench 2 continues to rotate 45°, so that the clamping part 21 is located at the pressing device 7. There are two sets of pressing devices 7, and the pressing devices 7 fix the copper sheets on the bottom plate. Then the clamping part 21 is moved to the discharging device 8, and the discharging device 8 moves the processed workpieces to the finished product area.

A second pushing member 74 is arranged on the frame 1, and a sliding block 77 is arranged at the acting end of the second pushing member 74. A second inclined surface 771 is formed at the top of the sliding block 77. The first inclined surface 761 corresponds to the second inclined surface 771. When the sliding block 77 slides, the first inclined surface 761 and the second inclined surface 771 move relative to each other and the first inclined surface 761 and the second inclined surface 771 always fit together, so that the second stamping member 76 moves up and down. The first stamping member 73 at the first station has a buffering effect and is a pre-pressing station, and the first stamping member 73 at the second station is a full pressing station. A first block 731 is arranged at the acting end of the first support 71 at the first station. A stamping block 732 is arranged on the first block 731. A second block 733 is arranged below the first block 731. A guide rod 734 is arranged on the second block 733. The guide rod 734 passes through the first block 731. The second block 733 and the first block 731 move relatively up and down. An elastic member 735 is sleeved on the guide rod 734. One end of the elastic member 735 abuts against the first block 731, and the other end of the elastic member 735 abuts against the second block 733. The stamping block 732 passes through the second block 733. When the second block 733 does not contact the bottom plate, the stamping block 732 does not protrude from the second block 733. When the second block 733 contacts the bottom plate, the elastic member 735 is compressed and the stamping block 732 gradually moves towards the bottom plate until it stamps the bottom plate. At this time, the second block 733 presses the bottom plate to prevent the bottom plate from moving.Furthermore, the copper sheet is stamped on the bottom plate through two sets of workstations, and the upper and lower stamping parts apply less force to the workbench 2.
