[0027] Embodiment 1, a furnace front ball replenishing jig, the furnace front ball replenishing jig comprises: a carrier base 1, a product body 2 and a carrier pressure plate 3.

[0028] Specifically, the upper side of the carrier base 1 is slidably sleeved with a product body 2 and a carrier pressing plate 3 in sequence, and the product body 2 can be clamped and positioned by the carrier base 1 and the carrier pressing plate 3 to keep the product body 2 flat as a whole, and a plurality of No. 1 magnets 4 are fixedly connected to the upper side of the carrier base 1, and a plurality of No. 2 magnets 5 corresponding to the positions of the No. 1 magnets 4 are fixedly connected to the lower side of the carrier pressing plate 3, and the carrier pressing plate 3 can be fixedly installed on the carrier base 1 through the attraction between the No. 1 magnets 4 and the No. 2 magnets 5, and a support plate 61 arranged in a "mouth" shape is slidably inserted on the upper side of the carrier pressing plate 3, and the support plate 61 can provide the product The warped part on the main body 2 is provided with installation space to prevent the baffle plate 6 from being disturbed and uneven after being inserted into the carrier pressure plate 3. The upper side of the support plate 61 is fixedly connected with the baffle plate 6. The side of the baffle plate 6 is penetrated with a plurality of goal holes 7 corresponding to the positions of the solder points on the product main body 2. The solder balls at the flat part can be directly installed on the product main body 2 through the goal holes 7. The upper end of the goal holes 7 is slidably inserted with a restraining block 8 for positioning the solder balls. The restraining block 8 can separate the solder points at the warped part from other solder balls, so that the solder balls at this part will not affect other solder balls after installation. Two sets of vertically arranged adjustment components are arranged on the side of the carrier pressure plate 3;

[0029] Furthermore, the positioning assembly includes a positioning bolt 31 and a support rod 32, and the positioning bolt 31 and the support rod 32 are respectively located at the two ends of the carrier pressure plate 3 and have the same axis. The positioning bolt 31 and the carrier pressure plate 3 are threadedly plugged, and the support rod 32 and the carrier pressure plate 3 are slidingly plugged. One end of the support rod 32 is fixedly connected to a fixing plate 33, and a spring 34 is fixedly connected between the fixing plate 33 and the carrier pressure plate 3. By rotating the positioning bolt 31 and the spring 34, the sliding of the baffle 6 can be controlled, so that the position of the goal hole 7 and the welding point at the raised position can be better matched.

[0030] In order to make the installation position of the carrier pressure plate 3 more precise, the upper side of the carrier base 1 of the present application is fixedly connected with a plurality of symmetrically arranged No. 1 positioning columns 11, and the side of the carrier pressure plate 3 is provided with a plurality of No. 2 positioning holes 35 for the No. 1 positioning columns 11 to slide and insert. The installation position of the carrier pressure plate 3 can be accurately located through the cooperation between the No. 1 positioning columns 11 and the No. 2 positioning holes 35, so that the No. 2 magnets 5 can better correspond to the No. 1 magnets 4.

The constraint block 8 and the goal hole 7 are slidably inserted in the slide grooves 71. This not only can accurately locate the sliding insertion position of the constraint block 8, but also can ensure that the constraint block 8 will not block the goal hole 7 and affect the installation of the solder ball.

[0034] In actual implementation, first, the product body 2 and the carrier pressure plate 3 are sequentially mounted on the carrier base 1. With the cooperation of the No. 1 magnet 4 and the No. 2 magnet 5, the carrier base 1 and the carrier pressure plate 3 can clamp and fix the product body 2 to ensure that the product body 2 is flat as a whole during installation. Then, the baffle 6 is slidably inserted into the carrier pressure plate 3. First, the solder balls of the flat solder joints are installed accordingly. Then, the goal hole 7 is adjusted to a suitable position through the positioning assembly. Then, the constraint block 8 is slidably inserted into the goal hole 7 corresponding to the solder joint at the raised position. After the solder ball at this position is installed and fixed on the product body 2, the installation is completed. This also ensures that the stability of the solder balls that have been installed will not be affected.
