Description

Technical Field

[0001] The utility model relates to the technical field of solder paste temperature recovery, in particular to a solder paste temperature recovery fixture. Background Art

[0002] Solder paste is usually refrigerated in a refrigerator, and the best refrigeration temperature is 5-10℃. Therefore, when the solder paste is taken out from the refrigerator, its temperature is much lower than the room temperature. If the bottle cap is opened without "warming up", it is easy to condense water vapor in the air and adhere to the solder paste. When passing through the reflow furnace, the water vapor will be rapidly vaporized due to strong heat, causing "tin explosion", generating solder beads, and even damaging components. The general warming method is to place it at room temperature for natural thawing. During the thawing process, make sure that the bottle cap is not opened.

[0003] In the field of electronic device processing, if the solder paste is not used up on the same day, it generally needs to be refrigerated to prevent it from losing its effectiveness. However, the solder paste must be used at room temperature, so it needs to be taken out of the refrigerator and placed at room temperature for a few hours to warm up. In actual application, operators often use solder paste that has not fully warmed up due to anxiety, which leads to quality problems. In addition, it takes a long time for the solder paste to warm up at room temperature, which is inconvenient to use. Utility Model Content

[0004] 1. Technical Problems Solved

[0005] The technical problem to be solved by the utility model is that when using solder paste, operators often use solder paste that is not fully warmed due to anxiety, which leads to quality problems, and the solder paste takes a long time to be warmed up at room temperature, which is inconvenient to use.

[0006] 2. Technical Solution

[0007] In order to solve the above technical problems, the technical solution provided by the utility model is: a solder paste reheating fixture, including a reheating box, a box cover is installed on the upper end of the reheating box, a plurality of equidistant through holes are provided on the box cover, a reheating cylinder is installed at the lower end of the through holes corresponding to the through holes, a plurality of equidistant ventilation holes are provided on the reheating cylinder, an electric push rod is installed on the inner bottom wall of the reheating cylinder, a clamping assembly is installed on the top of the electric push rod, a plurality of timers corresponding to the through holes are installed on the box cover, and a ventilation fan is installed on one side of the reheating box.

[0008] Furthermore, a control panel electrically connected to the electric push rod, the timer, and the ventilation fan is installed on one side of the temperature return box.

[0009] Furthermore, the clamping assembly includes a placement plate installed on the top end of the electric push rod, a pair of guide rods are symmetrically and vertically passed through the two sides of the placement plate, a positioning plate is fixed on the top end of the pair of guide rods, a limiting plate is fixed at the lower end of the guide rod, a spring wound around the outside of the guide rod is fixed between the placement plate and the limiting plate, and a handle is installed on the upper end of the positioning plate.

[0010] Furthermore, the placement plate is provided with a plurality of ventilation holes 2, a pair of ventilation holes are symmetrically provided on both sides of the temperature recovery box, and the ventilation fan is installed outside one of the ventilation holes.

[0011] Furthermore, a dustproof frame is installed outside the ventilation fan, and a dustproof net is installed outside the other ventilation port.

[0012] 3. Beneficial Effects

[0013] The advantages of the utility model compared with the prior art are:

[0014] 1. Pull up the handle through the clamping component to place the solder paste on the placement plate, then release the handle. Under the action of the spring, limit plate and guide rod, the positioning plate descends and presses the top of the solder paste, which can clamp and position solder pastes of different sizes; when the electric push rod contracts and the solder paste enters the reheating cylinder, the through hole is blocked by the positioning plate, so that the solder paste that has not been fully reheated cannot be taken out.

[0015] 2. The timer is used to limit the temperature recovery time of the solder paste. After the temperature recovery time is over, the signal is transmitted to the control panel. The control panel controls the electric push rod to push the solder paste out, and the solder paste can be used.

[0016] 3. Through the cooperation of a pair of vents and ventilation fans on the re-warming box, an airflow with the same temperature as the outside air flows through the re-warming box, and the airflow flows through the solder paste through the vent holes and vent hole 2, which reduces the time for the solder paste to return to temperature and is easy to use.

When the reheating time on the timer 6 ends, the signal is transmitted to the control panel 8, and the electric push rod 4 is controlled by the control panel 8 to push the solder paste out, and the solder paste can be used. When the solder paste has not reached the specified reheating time, it is located in the reheating cylinder 3 and cannot be taken out, which prevents the user from taking out the solder paste that has not been fully reheated for use, thereby affecting the welding quality.

[0026] Combined with Figure 3 The clamping assembly 5 includes a placement plate 9 installed on the top of the electric push rod 4, a pair of guide rods 10 are symmetrically and vertically passed through the placement plate 9 on both sides, a positioning plate 11 is fixed to the top of the pair of guide rods 10, a limiting plate 12 is fixed to the lower end of the guide rod 10, a spring 13 wound around the outside of the guide rod 10 is fixed between the placement plate 9 and the limiting plate 12, and a handle 14 is installed on the upper end of the positioning plate 11.

[0027] In combination with the above structure, when the clamping assembly 5 is used, the handle 14 is pulled up to place the solder paste on the placement plate 9, and then the handle 14 is released. Under the action of the spring 13, the limit plate 12, and the guide rod 10, the positioning plate 11 descends and presses the top of the solder paste. Solder pastes of different sizes can be clamped and positioned. The through hole 201 is blocked by the positioning plate 11, so that the solder paste that has not been fully warmed up cannot be taken out.

[0031] Combined with Figure 2 , Attachment Figure 4 A dustproof frame 15 is installed outside the ventilation fan 7, and a dustproof net 16 is installed outside the other ventilation port 101 to prevent external dust from entering the temperature recovery box 1.

[0032] The specific usage is as follows:

[0033] Pull up the handle 14 and place the solder paste on the placement plate 9, then release the handle 14. Under the action of the spring 13, the limit plate 12 and the guide rod 10, the positioning plate 11 descends and presses the top of the solder paste, so that solder pastes of different sizes can be clamped and positioned; start the corresponding timer 6, and control the electric push rod 4 to retract through the control panel 8 to allow the solder paste to enter the reheating cylinder 3; start the ventilation fan 7, and make the air flow through the solder paste through a pair of vents 101, ventilation holes 301, and ventilation hole 2 901 to reduce the time for the solder paste to reheat; when the reheating time on the timer 6 ends, transmit the signal to the control panel 8, and control the electric push rod 4 to push the solder paste out through the control panel 8, so that the solder paste can be used.

[0034] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
