For ordinary skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0024] In order to illustrate the technical solutions of the present application, the following specific embodiments are described.

[0025] Referring to Figures 1-3 is a structure diagram of a tin bar loading disc provided by an embodiment of the present application, the tin bar loading disc comprises a master disc and a sub-disc, the master disc is provided with first through holes arranged at intervals, the first through holes penetrate the master disc along the thickness direction of the master disc, the sub-disc is provided with second through holes arranged at intervals, the second through holes penetrate the sub-disc along the thickness direction of the sub-disc, and the master disc is loaded above the sub-disc;

[0026] As the mother and daughter disks move relative to each other, the first through hole of the mother disk and the second through hole of the daughter disk form a stacked hole, allowing the solder bar on the mother disk to pass through the first and second through holes and contact the hot plate surface of the hot press opening.

[0027] In the embodiments disclosed herein, such as Figures 1-3 As shown, the solder bar carrier includes a mother tray and a daughter tray. The mother tray has a first through hole arranged at intervals, and the first through hole penetrates the mother tray along the thickness direction. The daughter tray has a second through hole arranged at intervals, and the second through hole penetrates the daughter tray along the thickness direction. The mother tray is mounted on top of the daughter tray. As the mother tray and the daughter tray move relative to each other, the first through hole of the mother tray and the second through hole of the daughter tray form a stacked hole, so that the solder bar on the mother tray can pass through the first through hole and the second through hole and contact the hot plate surface of the hot press opening for pressing. This application uses a design where the female tray is at the bottom and the male tray is at the top. After inserting the male tray into the female tray, the first through hole on the male tray and the second through hole on the female tray do not coincide. Cut solder bars are placed into the first through hole of the male tray from above, ready for use. Before conducting a pressure uniformity test, the operator holds the long slot hollowed out along the long side of the female tray with both hands and feeds the solder bar tray into the opening of the hot press. After placing it in place, the male tray is pushed and pulled until the first through hole on the male tray and the second through hole on the female tray coincide, forming a stacked hole. At this time, the solder bars on the male tray fall from the stacked hole onto the surface of the hot platen in the opening of the hot press. During the pressure uniformity test, the solder bars are evenly spread on the surface of the hot platen in the opening of the hot press and then pressed together. After pressing, the thickness of the solder bars is measured sequentially using a micrometer. The range of the solder bar thickness is calculated to determine the pressing uniformity capability of the hot press. After the pressure uniformity test, the second through hole of the female tray is used to cover the pressed solder bars, and the solder bars are pulled out of the opening of the hot press and collected. As can be seen, this application inserts the mother plate into the daughter plate and pushes and pulls the mother plate until the first through hole on the mother plate coincides with the second through hole on the daughter plate to form a stacked hole. This allows the solder bar on the mother plate to fall from the stacked hole onto the hot plate surface of the hot press opening for pressing. The thickness of the solder bar after pressing is then used to judge the pressing uniformity of the hot press, thereby reducing the risk of burns to personnel and improving the accuracy of the pressure uniformity test of the laminator.
