Description

Technical Field

[0001] This utility model relates to the field of semiconductor manufacturing, and in particular to a reflow soldering device. Background Technology

[0002] Traditional inductor reflow soldering equipment often relies on manual labor or simple machinery to place stacked inductors one by one or in batches into the tray during the loading process. This is inefficient and makes it difficult to ensure that the materials are neatly arranged in single pieces in the tray matrix trough, which can easily lead to jamming, accumulation, or gaps. At the same time, the recycling of empty trays after reflow soldering and unloading often requires manual intervention or complex additional conveying systems. The lack of automation results in a poor production process, limited efficiency, and high labor costs. Utility Model Content

[0003] The purpose of this invention is to provide a reflow soldering device to solve the problem of low automation in the existing inductor reflow soldering process.

[0004] The technical solution of this utility model is: a reflow soldering equipment, including a soldering furnace, a material feeding assembly, and a feeding assembly; The material feeding component is equipped with a material box, which has an opening at the top and holds multiple materials stacked inside. The material box is connected to a tilting mechanism, which drives the material box to flip and tilt the materials into the feeding component. The feeding assembly includes a material tray with multiple material slots arranged in a matrix on the tray, each slot capable of holding a single material. A vibration mechanism and a feeding mechanism are provided in conjunction with the material tray. The material in the material box is poured into the vibration mechanism, which drives the material to fall into the material tray. The two ends of the feeding mechanism correspond to the material tray and the furnace cavity of the welding furnace, respectively. The material tray carries the material into the welding furnace under the drive of the feeding mechanism.

[0005] Preferably, the material feeding assembly includes a lifting mechanism, which includes a lifting rail arranged in a vertical direction, a lifting slider arranged on the lifting rail, the lifting slider running along the lifting rail under the drive of the lifting driver, and the tilting mechanism fixed on the lifting slider.

[0006] Preferably, the tilting mechanism includes a tilting base and a tilting driver connected to the lifting slider. The tilting base is rotatably connected to the lifting slider and can rotate around a horizontal axis under the drive of the tilting driver. The material box is disposed at the top of the tilting base.

[0007] Preferably, the vibration mechanism includes a vibration generator, the execution end of which is connected to a material distribution plate, and the material in the material box is poured into the material distribution plate; one side of the material distribution plate is set as a material loading station, and a lifting mechanism is provided to lift the material tray to be flush with the material distribution plate.

[0008] Preferably, one end of the feeding mechanism is set corresponding to the material loading station. The feeding mechanism includes a synchronous pulley arranged in the horizontal direction, a synchronous belt is sleeved on the synchronous pulley, and the material tray is placed on the synchronous belt and runs under the drive of the synchronous pulley.

[0009] Preferably, it includes a return conveyor line and a handling assembly; one end of the return conveyor line corresponds to the feeding mechanism, and the other end is connected to the end of the welding furnace away from the feeding mechanism. The return conveyor line and the handling assembly work together to transport the empty material tray that has flowed out of the welding furnace and completed the material picking back to the feeding mechanism.

[0010] Preferably, the conveying assembly includes a conveying base, on which a conveying gripper is provided. The conveying gripper is capable of clamping the material tray and reciprocating between the feeding mechanism and the return conveyor line under the drive of the transfer mechanism.

[0011] Compared with the prior art, the advantages of this utility model are: This application utilizes a tilting mechanism to precisely flip and dump piles of inductors onto a uniform material plate of a vibrating mechanism in one go. The vibration and lifting mechanisms work together to evenly disperse the material, ensuring that each particle falls neatly and individually into a material tray flush with the uniform material plate, significantly improving feeding efficiency and arrangement accuracy. The feeding mechanism smoothly conveys the fully loaded tray into the furnace. This greatly reduces manual intervention and enables automated continuous production of inductor reflow soldering, from efficient feeding and precise arrangement to stable conveying.

[0013] The present invention will be further described in detail below with reference to specific embodiments: like Figure 1 and Figure 2 As shown, a reflow soldering equipment is used to perform reflow soldering processing on materials (specifically inductors), including a soldering furnace 1, a material loading assembly 2, and a feeding assembly 3.

[0014] The material feeding assembly 2 includes a material box 4, in which multiple inductors are stacked. The material box 4 is connected to a tilting mechanism 21, which drives the material box 4 to tilt and pour the inductors into the feeding assembly 3. The feeding assembly 3 includes a material tray 5, which carries materials into the welding furnace 1. Figure 6 As shown, the material tray 5 has multiple material slots 51 arranged in a matrix. Each material slot 51 can hold a single material, so that the materials loaded in the material tray 5 can be arranged neatly.

[0015] To facilitate the transfer of material from the material box 4 into the material tray 5, this application includes a vibration mechanism 31 in conjunction with the material tray 5. The material in the material box 4 is poured into the vibration mechanism 31, which then drives the material to fall into the material tray 5. Figure 4 As shown, the feeding assembly 3 includes a feeding mechanism 32. The two ends of the feeding mechanism 32 correspond to the material tray 5 and the furnace cavity of the welding furnace 1, respectively. The material tray 5 carries the material into the welding furnace 1 under the drive of the feeding mechanism 32.

[0016] Specifically, such as Figure 3 As shown, the material feeding assembly 2 also includes a lifting mechanism 22. The lifting mechanism 22 includes a lifting rail 221 arranged vertically, and a lifting slider 222 is arranged on the lifting rail 221. The lifting slider 222 runs along the lifting rail under the drive of the lifting driver 223. The tilting mechanism 21 is fixed to the lifting slider 222. The lifting mechanism 22 enables the material box 4 to be fed at a low position and tilted into the vibration mechanism 31 at a high position.

[0017] The tilting mechanism 21 includes a tilting base 211 and a tilting actuator 212 connected to the lifting slider 222. The tilting base 211 is rotatably connected to the lifting slider 222 and can rotate around a horizontal axis under the drive of the tilting actuator 212. The material box 4 is disposed at the top of the tilting base 211. A hopper 23 is provided in conjunction with the material box 4, and the material in the material box 4 falls into the feeding mechanism 32 through the hopper 23. In this embodiment, the tilting actuator 212 is a servo motor.

[0018] The vibration mechanism 31 includes a vibration generator 311, the execution end of which is connected to a material distribution plate 312. Material in the material box 4 is poured into the material distribution plate 312 by the tilting mechanism 21. One side of the material distribution plate 312 is configured as a material loading station, in which a lifting mechanism 33 is provided. The lifting mechanism 33 drives the material tray 5 to move up and down, making the material tray 5 flush with the material distribution plate 312, thereby allowing the material falling on the material distribution plate 312 to smoothly fall into the material tray 5 under the action of the vibration generator 311. In this embodiment, the lower end of the lifting mechanism 33 is fixed to a base.

[0019] One end of the feeding mechanism 32 is set corresponding to the material loading station, including a synchronous pulley 321 arranged in the horizontal direction. A synchronous belt 322 is sleeved on the synchronous pulley 321. The bottom end of the material tray 5 located in the material loading station is placed on the synchronous belt 322 and runs under the drive of the synchronous pulley 321.

[0020] Combination Figure 1 As shown, to achieve the recycling of the material tray 5 after reflow soldering and material unloading, this application also includes a reflow conveyor line 6 and a handling component 7 configured in conjunction with the reflow conveyor line 6. The reflow conveyor line 6 is structurally similar to the feeding mechanism 32, with one end corresponding to the feeding mechanism 32 and the other end connected to the end of the welding furnace 1 away from the feeding mechanism 32. The reflow conveyor line 6 and the handling component 7 work together to re-transport the empty material tray 5 that has flowed out of the welding furnace 1 and completed material unloading back to the feeding mechanism 32.

[0021] like Figure 5As shown, the conveying assembly 7 includes a conveying base 71, on which a conveying gripper 72 is provided. The conveying gripper 72 can clamp the material tray 5 on the return conveyor line 6 through a clamping action, and under the drive of the transfer mechanism 73, the empty material tray 5 is transferred to the feeding mechanism 32. Subsequently, the feeding mechanism 32 carries the empty material tray 5 into the loading station, and under the drive of the lifting mechanism 33, it is flush with the material leveling plate 312 to reload the material. In this embodiment, the transfer mechanism 73 includes a first transfer module 731 arranged in the horizontal direction, and a second transfer module 732 arranged in the vertical direction on the first transfer module 731. Both the first transfer module 731 and the second transfer module 732 include a motor, a lead screw, a guide rail, and a slider, and together they can realize the conveying action of the conveying gripper 72 in the vertical plane.
