[0017] Examples, such as Figure 1-5 As shown, a WiFi antenna PCB board and antenna welding tool is used to clamp antennas and PCB board groups in batches for batch welding, and cut pre-cut marks between each PCB board for easy breaking. The above antenna is a copper wire with a spiral shape, and the antenna includes an antenna spiral part 102, an antenna welding end straight rod part 101 arranged at one end of the antenna spiral part 102, and an antenna signal transmission end straight rod part 103 arranged at the other end of the antenna spiral part 102; the above PCB board group is a group of PCB boards connected in sequence.

[0018] The specific structure of the utility model is as follows:

[0019] The invention comprises a base 1, and a placement groove 2 for clamping an antenna on the base 1, wherein the placement groove 2 comprises a first straight rod placement area 21 adapted to the straight rod portion 101 of the antenna welding end, a spiral portion placement area 22 adapted to the spiral portion 102 of the antenna, and a second straight rod placement area 23 adapted to the straight rod portion 103 of the antenna signal transmission end. The first straight rod placement area 21, the spiral portion placement area 22 and the second straight rod placement area 23 are coaxially arranged, and all three are rectangular grooves that are easy to process. The groove length of the first straight rod placement area 21 is shorter than the length of the straight rod portion 101 of the antenna welding end, the groove width is slightly larger than the diameter of the straight rod portion 101 of the antenna welding end, and the groove depth is larger than the radius of the straight rod portion 101 of the antenna welding end and smaller than the diameter of the straight rod portion 101 of the antenna welding end, so as to ensure that there is a gap between the two sides of the straight rod portion 101 of the antenna welding end and the first straight rod placement area 21 for easy access, and at the same time ensure that the straight rod portion 101 of the antenna welding end is exposed from the upper end surface of the base 1; the groove length of the second straight rod placement area 23 is shorter than the length of the straight rod portion 103 of the antenna signal transmission end, and the dimensional requirements of the groove depth and groove width are the same as those of the first straight rod placement area 21; because there will be errors in the size of the spiral portion machined on the copper wire, the groove length, groove depth and groove width of the spiral portion placement area 22 are all larger than the outer dimensions of the antenna spiral portion 102, and the antenna can be positioned by completely avoiding the first straight rod placement area 21 and the second straight rod placement area 23. The end of the second straight rod placement area 23 away from the spiral portion placement area 22 penetrates the side wall of the base 1. A positioning block 4 is provided on the side wall of one end of the second straight rod placement area 23 on the base 1. When placing, the end of the straight rod portion 103 at the antenna signal transmission end is placed against the positioning block 4, and the positioning block 4 serves as a reference surface. To facilitate the placement of the antenna, a placement slot 7 for placing the antenna is also provided on the base 1. The placement slot 7 is connected to the placement slot 2 and is located below the second straight rod placement area 23.

[0020] Before placing the antenna, the PCB board group must be placed first. A positioning groove 3 for clamping the PCB board group is provided at one end of the base 1 located in the first straight rod placement area 21. The positioning groove 3 is connected to the placement groove 2. Each placement groove 2 corresponds to each PCB board in the positioning groove 3, and the two are arranged in parallel. The groove depth of the positioning groove 3 is the sum of the groove depth of the first straight rod placement area 21 and the thickness of the PCB board. The base 1 is also provided with a placement notch 8 for facilitating the placement of the PCB board group. The placement notch 8 is connected to the positioning groove 3. The antenna is placed in the placement groove 2, and the end of the straight rod portion 101 of the antenna welding end extends out of the first straight rod placement area 21 and is located above the PCB board welding area 301, and is attached to the PCB board.

[0021] In order to prevent the antenna from being skewed, a clamping device 5 for clamping the antenna is provided on the base 1 above the placement groove 2, and the antenna is fixed in the placement groove 2 by the clamping device 5 and then welded. The clamping device 5 includes a pressing plate 51 hinged on the base 1 and located above the placement groove 2, a hinge 52 provided at one end of the pressing plate 51 and connected to the base 1, and the other end extends out of the side wall of the base 1 to facilitate opening the pressing plate 51, and a locking structure 53 is provided at the other end, and a clearance groove 511 adapted to the spiral part of the antenna is also provided at the lower end of the pressing plate 51. The locking structure 53 includes a first magnet 531 provided on the pressing plate 51, and a second magnet 532 provided on the base 1 and corresponding to the first magnet 531. After the PCB board assembly and the antenna are placed, the pressing plate 51 is closed, and the lower end surface of the pressing plate 51 is pressed on the straight rod portion 101 of the antenna welding end and the straight rod portion 103 of the antenna signal transmission end, and the pressing plate 51 is adsorbed by the suction force between the first magnet 531 and the second magnet 532, so that the antenna is firmly fixed in the placement groove 2.

[0022] In order to facilitate breaking and separating each PCB board, a pre-cutting device 6 for forming pre-cutting marks on the PCB board group is also provided on the base 1 above the positioning groove 3. The pre-cutting device 6 includes a knife seat 61 which can move up and down, and a group of blades 62 arranged on the knife seat 61. Each blade 62 is located in the middle of two adjacent PCB boards and is arranged parallel to the length direction of the PCB board. The length of the blade 62 is adapted to the length of the PCB board. The pre-cutting device 6 also includes a group of guide columns 63 arranged on the base 1 and located on both sides of the positioning groove 3, and the guide columns 63 are straight rod structures. The knife seat 61 is provided with guide holes 611 adapted to the guide columns 63. During operation, the blade 62 of the knife holder 61 is inserted downward through the guide hole 611 and onto the guide column 63, and is pressed downward, so that the blade 62 cuts a pre-cut mark on the PCB board assembly, and the operator can use the pre-cut mark to easily break and separate each PCB board. After cutting, the knife holder 61 is pulled out of the guide column 63 and put aside, so as not to interfere with the welding operation. It should be noted that the pre-cut operation can be completed before or after welding, and has no effect on welding.
