[0028] Example 1: Please refer to Figure 1-8The utility model provides a technical solution: an improved punching machine, including a punching machine 1, a feeding mechanism 2 is provided on the punching machine 1; two bases 3 are connected to the feeding mechanism 2, a supporting structure is installed on the two bases 3, four linear bearings 4 are installed on the supporting structure, the same material taking adjustment structure is installed on the two linear bearings 4 located on the same side, a plurality of suction nozzles 5 are installed on the two material taking adjustment structures, two electric push rods 6 are fixedly installed on one side of the two bases 3, and a protective structure is installed on the output end of the four electric push rods 6;

[0029] The supporting structure includes two aluminum fixing brackets 31, which are movably mounted on one side of the two bases 3.

[0030] The material picking adjustment structure includes a screw 41, which is connected to two corresponding linear bearings 4. A plurality of screw stepper motors 42 are threadedly mounted on the screw 41. A straight-line block 43 is fixedly mounted on one side of the screw stepper motor 42. The suction nozzle 5 is fixedly mounted on one side of the straight-line block 43. When the screw stepper motor 42 is driven, the screw stepper motor 42 can slide horizontally on the screw 41. The moving screw stepper motor 42 will drive the suction nozzle 5 to move through the straight-line block 43, so that the distance between two adjacent suction nozzles 5 can be adjusted. The positions of one suction nozzle 5 can be adjusted individually or all suction nozzles 5 can be adjusted simultaneously.

[0031] Furthermore, the inner wall of the linear bearing 4 is provided with a plurality of hidden grooves 34 , and the V-shaped screws 32 are movably installed in the hidden grooves 34 . When the V-shaped screws 32 are fully screwed into the V-shaped screws 32 , the V-shaped screws 32 will be located in the hidden grooves 34 , thereby avoiding interference with the movement of the screw stepper motor 42 .

[0032] Furthermore, a slot 44 is provided on the inner wall of the aluminum fixing bracket 31, the linear bearing 4 is fixedly installed in the slot 44, the screw stepper motor 42 is slidably installed in the slot 44, and the sliding screw stepper motor 42 can slide in the slot 44 on the linear bearing 4, thereby limiting the moving direction of the screw stepper motor 42.

[0033] Furthermore, the length of the base 3 is 622 mm, the length of the aluminum fixing bracket 31 is 725 mm, and the width and thickness of the aluminum fixing bracket 31 are both 30 mm.

[0034] Example 2: Figure 2-8In order to prevent the PCB board from falling off during the transportation process, a protective structure is arranged on the electric push rod 6, which includes a lifting plate 61, which is fixedly installed on the output ends of the four electric push rods 6, and two adjusting plates 62 are slidably installed on the lifting plate 61. One side of the two adjusting plates 62 is fixedly installed with an L-shaped support plate 63, and the top side of the lifting plate 61 is fixedly installed with a double-axis motor 64. The two output ends of the double-axis motor 64 are fixedly installed with an adjusting screw rod 65, and the two adjusting screw rods 65 are threadedly sleeved with a threaded seat 66. The two threaded seats 66 are respectively fixedly installed on one side of the two adjusting plates 62, and one end of the adjusting screw rod 65 is fixedly installed with a stopper 67, which is located on one side of the threaded seat 66. Two guard plates 610 are fixedly installed on the L-shaped support plate 63, and the inner wall of the lifting plate 61 is provided with four T-shaped slide grooves 68. T-shaped sliders 69 are slidably installed on each of the two adjusting plates 62. The four T-shaped sliders 69 are symmetrically fixed on one side of the two adjusting plates 62. An adjusting screw hole 611 is provided on the inner wall of the threaded seat 66. The adjusting screw rod 65 is threadedly installed in the adjusting screw hole 611. After the suction nozzle 5 is used to absorb the PCB board by using the feeding mechanism 2, the dual-axis motor 64 can be turned on to drive the two L-shaped support plates 63 to approach, so that the cross plates at the bottom of the two L-shaped support plates 63 are moved to the bottom side of the PCB board to block and protect it. At the same time, the two guard plates 610 on the L-shaped support plates 63 can be used to block and protect the side edges of the PCB board. Then, the four electric push rods 6 are driven so that the output end thereof drives the lifting plate 61 to move upward, thereby driving the L-shaped support plates 63 on both sides to move upward, so that the cross plates of the L-shaped support plates 63 are close to the PCB board, thereby preventing the PCB board from falling off when being transported. The remaining features are the same as those in Example 1.

[0035] The working principle is as follows: since the screw 41 is restricted by the linear bearings 4 on both sides and cannot rotate, when the screw stepper motor 42 is driven, the screw stepper motor 42 can slide horizontally on the screw 41, and the moving screw stepper motor 42 will drive the suction nozzle 5 to move through the I-shaped block 43, so that the distance between two adjacent suction nozzles 5 can be adjusted, and one suction nozzle 5 can be adjusted individually or the position of all suction nozzles 5 can be adjusted at the same time. The aluminum fixing bracket 31 can be installed with the base 3 by using the V-shaped screw 32 to pass through the hidden groove 34 and screwed into the V-shaped screw hole 33. After the suction nozzle 5 is adsorbed on the PCB board by using the feeding mechanism 2, the dual-axis motor 64 can be turned on, and the two output ends of the dual-axis motor 64 will respectively drive the two adjusting screws 65 to rotate, and the two rotating adjusting screws 65 can respectively drive the two threaded seats 66 to move and approach each other through the threaded cooperation with the two adjusting screw holes 611, wherein when the output end of the dual-axis motor 64 is driven to rotate in the opposite direction, the two The two threaded seats 66 move away from each other, and the two threaded seats 66 approaching each other will respectively drive the two adjusting plates 62 to move, so that the moving adjusting plates 62 drive the T-shaped slider 69 to slide in the T-shaped slide groove 68, thereby preventing the adjusting plates 62 from deviating, and then the two adjusting plates 62 approaching each other respectively drive the two L-shaped supporting plates 63 to approach each other, so that the cross plates at the bottom of the two L-shaped supporting plates 63 move to the bottom side of the PCB board to block and protect it, and at the same time, the two guard plates 610 on the L-shaped supporting plates 63 can be used to block and protect the side edges of the PCB board, and then drive the four electric push rods 6 so that the output end drives the lifting plate 61 to move upward, and then drives the L-shaped supporting plates 63 on both sides to move upward, so that the cross plates of the L-shaped supporting plates 63 are close to the PCB board, thereby preventing the PCB board from falling off when transporting the PCB board. After the PCB board is transported to the right place, the two adjusting plates 62 are controlled to unfold and rise, and the feeding mechanism 2 is used to make the suction nozzle 5 place the PCB board at the punching position of the punching machine 1.
