Description

Technical Field

[0001] The present invention relates to a high-temperature reflow furnace, and in particular to a fully automatic crystal high-temperature reflow furnace. Background Art

[0002] The current operation mode of quartz crystal high temperature reflow furnace:

[0003] The operation steps of the quartz crystal high temperature reflow furnace are to manually place the crystal into the reflow tray, and then place the reflow tray on the reflow oven chain. The reflow tray with the crystal automatically rolls along the chain into the reflow oven temperature zone to perform the crystal over-temperature operation.

[0004] However, the quartz crystal high-temperature reflow furnace not only takes up a large space, but also uses manual adding of crystals to the reflow tray, pouring the crystals into the reflow tray, and entering the reflow high-temperature zone for operation. Five reflow trays can be placed in sequence at the same time. The reflow tray is not cooled when it comes out of the reflow oven outlet, and high-temperature protective gloves must be worn. There is a risk of burns when taking it. In addition, when the crystals are poured from the reflow tray into the crystal box, some crystals will fall onto the table. There is also a high probability of residual crystals on the reflow tray, which can easily cause mixing accidents when adding materials next time. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a fully automatic crystal high-temperature reflow furnace which improves production efficiency, reduces occupied space and eliminates potential safety hazards.

[0006] The technical solution adopted by the present invention is: the present invention includes a frame, a crystal conveying device is arranged on the frame, a discharge bin is obliquely arranged at one end of the crystal conveying device, a feeding device is arranged at the discharge port of the discharge bin, a reflow furnace is arranged at the other end of the crystal conveying device, a crystal recovery box is arranged below the end of the crystal conveying device, and a rotating material receiving and cooling device is arranged between the end of the crystal conveying device and the crystal recovery box.

[0007] Furthermore, an MCU controller is provided in the frame, a control panel is provided at the front end of the frame, and the crystal conveying device, the feeding device, the reflow furnace, the rotary material receiving and cooling device and the control panel are all electrically connected to the MCU controller.

[0008] Furthermore, the feeding device includes a motor seat, a driving motor, a rotating rod, a rocker arm, a moving guide rail, a moving block and a moving plate, the motor seat is installed at the front end of the discharging bin, the driving motor is installed on the motor seat, one end of the rotating rod is connected to the output shaft of the driving motor, the other end of the rotating rod is connected to one end of the rocker arm, the moving guide rail is installed at the side end of the discharging bin, the moving block is slidably installed on the moving guide rail, and the moving block is connected to the other end of the rocker arm, a plurality of the moving plates are installed on the moving block, the other end of the moving plate is located above the discharging bin, and the lower end of the moving plate is installed with a soft rubber plate for pushing materials that extends into the discharging bin.

[0009] Furthermore, the crystal conveying device comprises a driving roller and a redirecting roller respectively located at two ends of the frame, a conveying mesh belt is coiled between the driving roller and the redirecting roller, and a material guide chute plate is butt-jointed at the end of the conveying mesh belt.

[0010] Furthermore, the rotary material receiving and cooling device comprises two symmetrically arranged brackets, a rotary material receiving box is hinged between the two brackets, an opening is provided at the bottom of the tail end of the rotary material receiving box, a rotary cylinder connected to the rotary material receiving box is provided on one of the brackets, the material guide chute plate and the crystal recovery box are both on the rotating track of the rotary material receiving box, and the outlet of the material guide chute plate is located directly above between the two brackets, and the crystal recovery box is located at the rear end of the rotary material receiving box.

[0011] Furthermore, a material basket bracket is arranged above the reflow furnace, and a plurality of crystal raw material boxes are placed on the material basket bracket.

[0012] The beneficial effects of the present invention are as follows: the present invention directly places the crystal into the inclined discharge bin, and flows to the discharge port of the discharge bin under the action of gravity, and pushes the crystal from the discharge port into the reflow furnace through the feeding device. The crystal after passing through the reflow furnace falls into the rotating material receiving and cooling device for flipping and cooling, and then automatically enters the crystal recovery box. Therefore, compared with the existing reflow tray reflow furnace operation method, the present invention can effectively save space. Because the reflow tray is large, a larger transmission device is required, which occupies a larger area, and the crystal can be automatically connected to the crystal recovery box through the rotating material receiving and cooling device, which avoids the risk of scalding when manually taking the reflow tray, and also avoids the problem of crystal falling or remaining on the reflow tray. It also effectively improves production efficiency and saves labor costs. In addition, flipping the crystal by the rotating material receiving and cooling device can effectively accelerate the cooling of the crystal. BRIEF DESCRIPTION OF THE DRAWINGS
