DETAILED DESCRIPTION

[0020] The present invention is further described below in conjunction with embodiments, which are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, other embodiments obtained by ordinary technicians in the field without creative work are all within the scope of protection of the present invention.

[0021] Embodiment 1:

[0022] like Figure 1 As shown, a tooling for producing a satellite downconverter includes: a polarization needle mounting base plate 1, a polarization needle fixing plate 6, a PCB silk screen patch fixing plate, and an antenna fixing plate 12. The polarization needle mounting base plate 1 is provided with a plurality of polarization needle mounting holes 3, and the plurality of polarization needle mounting holes 3 are arranged in two opposite rows, and a slide groove 2 is provided between each row of polarization needle mounting holes 3 and the side wall of the polarization needle mounting base plate 1. Figure 2 There are two polarization pin fixing plates 6, which are respectively arranged in two slide grooves 2 opposite to each other. Guide pillars 5 are arranged around the polarization pin mounting base plate 1. The guide pillars 5 are used to facilitate rapid positioning with the PCB screen printing patch fixing plate, so that the polarization pin inserted into the polarization pin mounting hole 3 can be quickly connected with the corresponding polarization pin welding position on the PCB board fixed on the PCB screen printing patch fixing plate, which is convenient for welding.

[0023] like Figure 3 As shown, the polarization needle fixing plate 6 is slidably arranged in the slide slot 2, and a polarization needle limiting groove 7 for fixing the polarization needle is provided on one side wall of the polarization needle fixing plate 6, and the number of the polarization needle limiting grooves 7 is equal to the number of the slide slots 2 and is arranged correspondingly; the polarization needle placed in the polarization needle mounting hole 3 can be further limited by the polarization needle fixing plate 6 arranged in the slide slot 2, because the polarization needle mounting hole 3 is generally set as a rectangular hole for the convenience of installation, and the size is slightly larger than the bottom of the polarization needle, so that the polarization needle will have a position deviation in the polarization needle mounting hole 3 after installation, and by arranging the polarization needle fixing plate 6 in the slide slot 2, the polarization needle limiting groove 7 of the polarization needle fixing plate 6 can just clamp the polarization needle, and limit the displacement of the polarization needle. The position of the polarization needle after being limited just corresponds to the corresponding polarization needle welding position on the PCB board.

[0024] In order to more conveniently fix the polarization needle, a trumpet-shaped guide opening 8 is provided at the opening of the polarization needle limiting groove 7. This can eliminate the assembly error of the polarization needle and facilitate the polarization needle limiting groove 7 of the polarization needle fixing plate 6 to be inserted into the polarization needle.

[0025] In this embodiment, two guide columns are provided on the antenna fixing plate 12, and the antenna fixing plate 12 is slidably set in the guide groove 11 of the PCB silk screen patch fixing plate through the guide columns. The antenna fixing plate 12 is provided with a guide groove 13 for inserting the satellite receiving antenna into the PCB board.

[0026] like Figure 4 and 5 As shown, the PCB silk-screen patch fixing plate is provided with a fixing groove for fixing the PCB board, and guide grooves 11 arranged opposite to each other are provided on both sides of the fixing groove, and guide holes 10 cooperating with the guide pillars 5 are provided around the PCB silk-screen patch fixing plate; the PCB board is fixed on the PCB silk-screen patch fixing plate through the fixing groove, and then the antenna fixing plate 12 is slidably set in the guide groove 11 through two guide pillars, and then rests against the edge of the guide groove 11, so that the position on the PCB board corresponding to the guide groove 13 on the antenna fixing plate 12 is the position where the Beidou satellite receiving antenna is inserted, and the guide pillar of the antenna fixing plate 12 cannot move to the left and right positions in the guide groove 11.

[0027] At the same time, the antenna fixing plate 12 also has the effect of pressing the PCB board. When it is designed, the weight is increased according to the degree of deformation of the PCB board to prevent the PCB board from warping during reflow soldering, resulting in polarization pin welding and uneven Beidou satellite receiving antenna, thereby playing a suppressing role.

[0028] A through vent 4 is provided on the polarization pin mounting base plate 1 between the two rows of polarization pin mounting holes 3. The vent 4 is mainly used to facilitate the hot air flow during reflow soldering and improve the soldering quality.

[0029] In this embodiment, two pairs of guide grooves 11 are arranged opposite to each other on the PCB silk screen patch fixing plate, and the two pairs of guide grooves 11 are arranged opposite to each other in the vertical direction. An antenna fixing plate 12 is arranged in each pair of guide grooves 11, and the guide grooves 13 of the two antenna fixing plates 12 are arranged opposite to each other. In actual use, the number of antenna fixing plates 12 can be increased or decreased according to the number of Beidou satellite receiving antennas on the actual PCB board.

[0030] When in use, the PCB board is placed on the PCB silk screen patch fixing plate to first complete the silk screen solder paste and SMT patch normally; at the same time, another line can synchronously use the polarization pin mounting base plate 1 and the polarization pin fixing plate 6 to complete the fixation of the polarization pin;

[0031] Then, the PCB silk-screen patch fixing plate carrying the PCB board is sleeved on the guide column 5 of the polarization needle mounting base plate 1 through the guide hole 10 set thereon, so that the polarization needle is plugged into the PCB board. Then, the antenna fixing plate 12 is set in the guide groove 11 through the guide column and slid into place, the insertion position of the Beidou satellite receiving antenna is determined, and the insertion of the Beidou satellite receiving antenna is completed. Figure 6 As shown in the figure, the PCB board equipped with the polarization pin and Beidou satellite receiving antenna is reflowed together with the various toolings, without the need for machine spot welding or manual welding, which improves welding efficiency and saves costs. The tooling is made of high temperature resistant material, and the tooling itself cannot be warped or deformed during reflow soldering.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
