[0021] Example 1 Please refer to Figures 1 to 4 As shown, it illustrates the specific structure of a preferred embodiment of the present invention, which is a pallet-type anti-scratch conveying mechanism.

[0022] In this process, the circuit boards are first lifted by a support rod before being transported. This design avoids damaging the circuit boards.

[0023] This application provides a pallet-type anti-scratch conveying mechanism, including a lower mold base 10 and a lower template 12 disposed on the lower mold base 10; a first suction device 20 and a second conveying device are disposed on the lower mold base 10; the first suction device 20 includes a first support rod 23 capable of being raised and lowered, and a first suction cup 26 disposed on the first support rod 23; the second suction device 30 includes a second support rod 33 capable of being raised and lowered, and a second suction cup 34 disposed on the second support rod 33; a clearance channel 13 is provided on the lower template 12; the first support rod 23 and the second support rod 33 can move back and forth in the clearance channel 13. A first servo motor drives the first suction device 20 to move, and a second servo motor drives the second conveying device to move. The first support rod 23 and the second support rod 33 are hollow tubes, which can reduce weight. When the pallet-type anti-scratch conveying mechanism is working, the circuit board is placed on the first support rod 23, and the first suction cup 26 sucks up the circuit board; then the circuit board is conveyed to the lower template 12 for punching. After the circuit board is punched, the second support rod 33 lifts the circuit board, and the second suction cup 34 holds the circuit board in place; then the circuit board is conveyed to the unloading position. Therefore, this design eliminates the problem of circuit board scratches, ensuring higher quality.

[0024] Preferably, the first suction device 20 further includes a first sliding seat 21, a first cylinder 22 disposed on the first sliding seat, and a first spring rod 24; wherein, the output end of the first cylinder 22 and the first spring rod 24 are connected to the first end of the first support rod 23; the first cylinder 22 can lift the first support rod 23; the first spring rod 24 can pull the first support rod 23. The first sliding seat 21 can slide back and forth on the main slide rail 11; the first cylinder 22 drives the first support rod 23 to move up and down against the circuit board. The first support rod 23 is a hollow tubular structure, and a connecting rod 25 is disposed on the first spring rod 24, the first connecting rod 25 being inserted into the end of the first support rod 23. The insertion of the first connecting rod 25 into the end of the first support rod 23 allows the first spring rod 24 to provide a certain pulling force to the first support rod 23, which can balance the weight of the first support rod 23 and improve the stability of the first support rod 23. The hollow tubular structure can reduce the weight of the first support rod 23 and has better resistance to deformation.

[0025] Preferably, the first sliding seat 21 is provided with a first sliding module 210, and the first support rod 23 is disposed in the first sliding module 210. The first sliding module 210 includes a first slide rail 211 and a first slider 212 that slides on the first slide rail 211. A first limiting pin 213 is disposed on the side of the first slide rail 211. The first limiting pin 213 can stop the first slider 212. When the first slider 212 slides on the first slide rail, the first limiting pin 213 can stop the first slider 212. Therefore, the first limiting pin 213 can control the sliding amount of the first slider 212, and thus control the lifting amount of the first support rod 23. The structure is simple and ingenious.

[0026] Preferably, the second suction device 30 further includes a second sliding seat 31 and a second cylinder 32 disposed on the second sliding seat; the output end of the second cylinder 32 is connected to the second support rod 33, and the second cylinder 32 can lift the second support rod 33. The second sliding seat 31 can slide back and forth on the main slide rail 11, and the second cylinder 32 can lift the second support rod 33, thereby allowing the circuit board to be lifted.

[0027] Preferably, a second sliding module 310 is provided on the second sliding seat 31; the second support rod 33 is disposed on the second sliding module 310; the second sliding module 310 includes a second slide rail 311, a second slider 312 sliding on the second slide rail 311, and a bracket 313 disposed on the second slider 312; the second support rod 33 is disposed on the bracket 313; a second limiting pin 314 is provided on the side of the second slide rail 311; the second limiting pin 314 can stop the second slider 312. The two second sliders 312 synchronously lift the bracket 313, and the second support rod 33 moves upward. The second limiting pin 314 can stop the second slider 312 and can be used to control the up and down movement range of the second support rod 33. The structure is simple and ingenious.

[0028] Preferably, the lower mold base 10 is provided with a main slide rail 11, with a first belt groove on the outer side of the main slide rail 11 and a second belt groove on the inner side. The first belt 214 in the first belt groove is connected to the first suction device 20, and the second belt 315 in the second belt groove is connected to the second suction device 30. The first slide and the second slide share a main slide rail 11, but different main slide rails 11 can be configured as needed. Sharing a main slide rail 11 saves costs. The first servo motor 215 drives the first belt to move, and the second servo motor 316 drives the second belt to move. The first belt drives the first slide to slide, and the second belt drives the second slide to slide. This drive structure is simple and efficient. The first slide and the second slide can be connected to the corresponding belt by clamping, and the first suction device 20 and the second suction device 30 can slide on the main slide rail 11.

[0029] Please refer to Figure 1 As shown, the first suction cup 26 is located at the right end of the first support rod 23; the second suction cup 34 is located at the right end of the second support rod 33. The circuit board is fed in from the left, punched, and then exits from the right. The positioning of the first suction cup 26 and the second suction cup 34 facilitates smoother movement of the circuit board. Of course, this is not the only design; the positions of the first suction cup 26 and the second suction cup 34 can be set in different locations as needed, such as the middle or the left end, without specific limitations.

[0030] Example 2 Example 2 includes the pallet-type anti-scratch conveying mechanism of Example 1, and the same parts will not be described again. The circuit board punching die includes the aforementioned pallet-type anti-scratch conveying mechanism; a punch is provided on the upper die, and the upper template and lower template 12 of the upper die are closed. The punch punches holes in the circuit board on the lower template 12. During punching, the first suction device 20 places the circuit board on the lower template 12, the pressure plate presses down on the circuit board, and then the punch punches holes in the circuit board. The second suction device 30 transfers the punched circuit board. This design can prevent scratches during the transfer of the punched circuit board.

[0031] In summary, the key design feature of this utility model is that during loading, the first support rod 23 lifts the circuit board while the first suction cup 26 holds the circuit board in place; during unloading, the second support rod 33 lifts the circuit board while the second suction cup 34 holds the circuit board in place.
