The flattening driving member 163 is used to drive the linkage member 161 to drive the pressing member 162 to flatten the circuit board 200 along the Y-axis direction before the bending member 154 presses the circuit board 200.

[0115] Therefore, the flattening mechanism 160 can adjust the placement flatness of the circuit board 200 in the Y-axis direction before the bending member 154 presses the circuit board 200 , which is helpful to improve the bending accuracy of the circuit board 200 .

[0116] In some embodiments, there are multiple carriers 123, first positioning members 133, second positioning members 143 and bending members 154, each carrier 123 is used to support a circuit board 200, and multiple carriers 123, multiple first positioning members 133, multiple second positioning members 143 and multiple bending members 154 correspond to each other. Correspondingly, there are multiple supporting grooves 1222a, each supporting groove 1222a receives a carrier 123 and is provided with an elastic body 1222d, there are multiple pressing members 162, multiple pressing members 162 are arranged at intervals along the Y-axis direction, and each pressing member 162 can flatten two circuit boards 200 at the same time.

[0117] Therefore, the multiple carriers 123 , the multiple first positioning members 133 , the multiple second positioning members 143 and the multiple bending members 154 are all in one-to-one correspondence, so that the circuit board forming machine 100 can form multiple circuit boards 200 at the same time, thereby improving the forming efficiency of the circuit boards 200 .

[0118] See also Figure 2In some embodiments, the circuit board forming machine 100 further includes a protective cover 170 and a safety grating 180. The protective cover 170 is disposed on the workbench 110 and is provided with a storage cavity 170a. A feeding window 170b is provided on the side of the storage cavity 170a facing the material loading position 110a. The first positioning mechanism 130, the second positioning mechanism 140 and the bending mechanism 150 are all stored in the storage cavity 170a. The safety grating 180 is connected to the protective cover 170 and is disposed on one side of the feeding window 170b, and is used to detect whether there is an object in the feeding window 170b.

[0119] Therefore, the protective cover 170 can prevent external components from colliding with the first positioning mechanism 130, the second positioning mechanism 140 and the bending mechanism 150, which is beneficial to improving the service life of the circuit board forming machine 100. In addition, when the safety grating 180 detects an object at the feeding window 170b, it can trigger the relevant components in the circuit board forming machine 100 to stop the circuit board forming machine 100, thereby improving the operating safety of the circuit board forming machine 100.

[0120] Here, taking a single carrier 123 and a single circuit board 200 as an example, the working process of the circuit board forming machine 100 is roughly as follows:

[0121] First, the carrier 123 carrying the circuit board 200 is placed in the support groove 1222a of the feeding mechanism 120 at the loading position 111a, and the feeding drive 121 drives the sliding frame 1221 to drive the support 1222 to move from the loading position 111a to the processing position 111b;

[0122] Secondly, the first driving member 131 drives the first heating component 132 to drive the first positioning member 133 to move along the X-axis, so that the first positioning member 133 abuts the carrier 123 along the X-axis direction to the side wall of the supporting groove 1222a, and the second driving member 141 drives the second heating component 142 to drive the second positioning member 143 to move along the Y-axis, so that the second positioning member 143 abuts the carrier 123 along the Y-axis direction to the side wall of the supporting groove 1222a;

[0123] Then, the flattening driving member 163 drives the linkage member 161 to drive the pressing member 162 to flatten the circuit board 200 along the Y-axis direction;

[0124] Subsequently, the third driving member 152 drives the third heating assembly 153 to drive the bending member 154 to move along the Z-axis direction, so that the bending slope 154a of the bending member 154 presses the circuit board 200 onto the positioning slope 143a of the second positioning member 143;

[0125] Finally, the first heating element 1323 heats the first heat conductive element 1322 to heat the first positioning element 133 to a preset temperature, and transfers the temperature to the circuit board 200 through the carrier 123. The second heating element 1423 heats the second heat conductive element 1422 to heat the second positioning element 143 to a preset temperature, and transfers the temperature to the circuit board 200 through the carrier 123. The third heating element 1533 heats the third heat conductive element 1532 to heat the bending element 154 to a preset temperature. The bent circuit board 200 is heated in the X-axis direction, the Y-axis direction and the Z-axis direction respectively until the bent circuit board 200 is formed.

[0126] It should be noted that the heating process of the first positioning member 133 and the second positioning member 143 can be performed before they contact the carrier 123 , and the heating process of the bending member 154 can be completed before they contact the circuit board 200 .
