With particular reference to fig. 5 and 6, an embodiment for driving the arc-shaped cover 7 to rotate relatively open or closed is provided;

in the embodiment, the sleeve 2 is driven to move up and down through an external structure, and due to the fixing effect of the vertical rod 3 on the inner tube 4, the sleeve 2 and the inner tube 4 can slide relatively, then the sleeve 2 drives the fixing shaft 5 to move up and down, so that the placing plate 6 is driven to move up and down, and the purpose of opening or closing the two arc-shaped covers 7 through mutual rotation is achieved by utilizing the meshing effect of the arc-shaped racks 13 and the vertical racks 14;

in the process, the inner tube 4 is in a fixed state and is relatively slid by the movement of the sleeve 2;

the same can also be achieved by fixing the sleeve 2, by moving the inner tube 4 up and down.

In a further preferable implementation, the outer walls of the inner tube 4 and the sleeve 2 are both provided with placing openings 17, the chip 9 is arranged below the placing plate 6, and when the two arc-shaped covers 7 rotate to the place above the placing plate 6 and are closed, the two placing openings 17 are communicated;

the outer wall of the casing 2 is also provided with a baffle 18 which can close the placing opening 17.

Specifically, referring to fig. 5 and 6, the chip 9 can be conveniently placed below the placing plate 6 through the placing openings 17, when the inner tube 4 and the sleeve 2 slide relatively to drive the arc cover 7 to rotate, the two placing openings 17 can be staggered with each other to seal the inner tube 4, and in the process of moving the inner tube 4 and the sleeve, the placing openings 17 cannot be communicated with the upper cavity 20 and the lower cavity 19, so that the air tightness is ensured;

the placing opening 17 can be externally sealed by the baffle 18, so that external impurities are prevented from entering the interior.

In a further preferable implementation, the top and the bottom of the inner tube 4 are both communicated with vent pipes 15, electromagnetic valves 16 are installed in the two vent pipes 15, the top of the sleeve 2 is communicated with an exhaust pipe 21 capable of discharging air in one direction, the top of the base 1 is installed with at least three gas tanks 22 respectively used for filling mixed gas of oxygen and carbon dioxide, high-temperature water vapor and gaseous reducing agent for reducing copper oxide, the three gas tanks 22 are all communicated with the bottom of the sleeve 2 in one direction through guide pipes, and the inner wall of the sleeve 2 below the inner tube 4 is installed with a gas pressure sensor 23;

Referring to fig. 1, 3 and 5 to 6, it can be seen from the foregoing that when the chip 9 is placed at the bottom of the placing plate 6, it is in the state shown in fig. 5, and then when the sleeve 2 moves upwards and drives the placing plate 6 to move upwards through the fixing shaft 5, the two arc covers 7 rotate downwards and close, at the same time, the space in the upper cavity 20 increases, and the internal pressure decreases, so as to generate a negative pressure, whereas the space in the lower cavity 19 decreases, so as to increase the internal pressure, so as to generate a high pressure;

then, after the two arc-shaped covers 7 rotate to the lower part and are closed, the placing plate 6 is positioned at a closed ring, the closed ring is attached to the outer wall of the arc-shaped covers 7, the closed ring is not shown in the figure, and due to the existence of the vertical racks 14, the upper space and the lower space of the placing plate 6 cannot be completely separated by the closed ring, but only most part of the space needs to be isolated;

at the moment, the two electromagnetic valves 16 are opened, under the action of different pressures of the upper cavity and the lower cavity, the mixed gas of the oxygen and the carbon dioxide, the high-temperature water vapor and the gaseous reducing agent for reducing the copper oxide in the lower cavity 19 enters the inner tube 4, enters the arc cover 7 through the air holes in the two arc covers 7, then passes through the chip 9 and is sucked into the upper cavity 20 through the air holes 10 and the air pipe 15 to form a gas flow path, so that the lead can be fully contacted with the reactant, the oxidation speed of the lead can be improved to a certain degree, and under the action of a closed ring, most of the mixed gas can intensively pass through the arc covers 7;

since the solder part of the chip which is just manufactured and processed is not oxidized to form an oxide layer, the chip can reflect light when being irradiated by a light source, so that the detection result is influenced, and an oxide film with darker color can be quickly formed by increasing the oxidation speed.

Meanwhile, due to environmental reasons, copper at pins of the chip 9 can also generate oxidation reaction to generate copper oxide, so that the quality of the chip 9 is influenced, the copper oxide can be reduced under the action of a gaseous reducing agent, the oxidation speed of the copper oxide is inhibited, and the chip 9 is prevented from being damaged;

the gaseous reducing agent is preferably gaseous absolute ethyl alcohol and the like, and can be conveniently mixed with other gases such as oxygen and the like to be input in the gaseous state, and meanwhile, the oxidation reaction of the lead is not influenced.

Along with the flowing of the gas, the air pressure of the upper cavity and the lower cavity can be gradually restored to the standard air pressure, at the moment, the two electromagnetic valves 16 are closed, and then the sleeve 2 is driven to move downwards, so that the two arc-shaped covers 7 can be driven to rotate and the chip 9 can be detected;

in the process, the gas in the upper cavity 20 is discharged from the exhaust pipe 21 through extrusion, the lower cavity 19 replenishes the gas from the three gas tanks 22 through the guide pipe, so that the soldering oxidation process, the subsequent chip 9 detection process and the gas replenishment process can be completed through the up-and-down movement of the sleeve 2, and the gas replenishment quantity tends to be constant each time due to the up-and-down movement of the sleeve 2, so that the time for oxidizing the soldering part and the quantity of reactants at each time are the same or equal, the oxidation effect of lead can be ensured, copper can be prevented from being in an easily-oxidized environment for a long time, and the chip 9 is prevented from being additionally damaged.

Referring to fig. 6 and 8 in particular, as can be seen from the foregoing, when the sleeve 2 moves upward to rotate the two arc-shaped covers 7 downward and close, the protrusion 25 is inserted into the groove 26 and contacts the trigger switch 27, and then the trigger switch 27 controls the solenoid valve 16 to open, so as to achieve the automatic ventilation effect;

then when the sleeve 2 moves downwards, the projection 25 is separated from the trigger switch 27, so as to achieve the purpose of automatically closing the vent pipe 15.

In a further preferred implementation, the detection assembly comprises a groove formed in the inner wall of the arc-shaped cover 7, and a detection lens 11 and a radiation lamp 12 are arranged in the groove side by side;

and the two sets of detection components are symmetrically arranged about the fixed shaft 5.

Specifically, referring to fig. 6 and 7, when the arc-shaped cover 7 rotates, the chip 9 can be irradiated by the irradiation lamp 12, and then the detection is performed by the detection lens 11, as can be seen from the foregoing, the oxide layer of lead can avoid the phenomenon of light reflection when the irradiation lamp 12 irradiates, so that the detection accuracy is improved;

and because of the wrapping effect of the inner tube 4 and the sleeve 2, the influence of an external light source on the irradiation of the spotlight 12 can be avoided.

In a further preferred implementation, the device further comprises a fixing element 8 for fixing the chip 9, a clamping groove is formed in the bottom of the placing plate 6, and the fixing element 8 is detachably mounted in the clamping groove.
