Description

Technical Field

[0001] This utility model belongs to the field of DIP welding technology, specifically a device for DIP welding on a production line. Background Technology

[0002] The core task of DIP soldering equipment is to wet the PCB pads and component leads with molten solder to form solder joints with high mechanical strength and good conductivity, thus achieving circuit continuity. Unlike SMT reflow soldering, DIP soldering is mainly for through-hole components. The typical equipment is a wave soldering machine, which is a crucial link in the DIP production line. A typical DIP soldering production line uses a solder pot, which consists of an external furnace body for mounting heating equipment and a pot for holding molten solder. During operation, solder blocks are placed in the pot, and the machine heats the pot to melt it. Soldering is then performed using the molten solder. However, the following drawbacks still exist:

[0003] Because of the open design of the furnace basin, workers are easily exposed to molten solder during operation, which can cause burns. Utility Model Content

[0011] Preferably, the end block is symmetrically mounted with side plates on the side away from the fixed axis, and the two side plates are symmetrically arranged on both sides of the rotating arm. A second rotating shaft is fixedly mounted on the side plate and is rotatably connected to the side plate.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0027] Depend on Figures 1-6 The present invention includes a tin furnace body 1, a heating tank 2 is provided at the top of the tin furnace body 1, and a molten tin storage component 3 is provided at the top of the tin furnace body 1. The molten tin storage component 3 includes a furnace basin 301 installed inside the heating tank 2, and a shielding and protective component 302 is provided at the top of the furnace basin 301.

[0028] The shielding and protective component 302 includes a baffle 3021 disposed on the top of the furnace basin 301. The baffle 3021 has evenly spaced through-hole grooves 3022. A guide pipe 3024 is fixedly installed at the top of the baffle 3021. Connecting seats 303 are symmetrically installed at one end of the top of the furnace basin 301. A first rotating shaft 3023 is fixedly installed at the end of the baffle 3021 near the connecting seat 303. The two ends of the first rotating shaft 3023 are rotatably connected to the two connecting seats 303 respectively. The baffle 3021 is located away from the first rotating shaft 3023. One end of 023 is provided with a connecting fastener 305, and a baffle 3021 with a through-hole groove 3022 is provided above the furnace basin 301. This greatly improves the unstable quality and inconsistent solder joints that occurred during manual soldering, and also reduces the risk of employees being burned during operation. At the same time, a guide tube 3024 is provided on the baffle 3021 to raise the tin surface and avoid the risk of other components falling off during the soldering process of the through-hole components. This also reduces the time spent on applying high-temperature tape over a large area and improves the efficiency of the tinning operation.

[0029] The connecting fastener 305 includes a fixed shaft 3051 fixedly installed on the baffle 3021 at the end away from the first rotating shaft 3023. End blocks 3052 are symmetrically installed at both ends of the fixed shaft 3051. A rotating arm 3054 is provided on the side of the end block 3052 away from the fixed shaft 3051, perpendicular to the fixed shaft 3051. The two rotating arms 3054 are symmetrically arranged on both sides of the solder pot body 1. A handle 3056 is fixedly installed at the bottom end of the rotating arm 3054. Side plates 3053 are symmetrically installed on the side of the end block 3052 away from the fixed shaft 3051, symmetrically arranged on both sides of the rotating arm 3054. A second rotating shaft 3055 is fixedly installed on the side plate 3053, rotatably connected to the side plate 3053. An arc-shaped locking rod 3057 is fixedly installed on the side of the rotating arm 3054 near the solder pot body 1. The machine body 1 has symmetrical arc-shaped slots 304 on both sides. Arc-shaped locking rods 3057 are inserted into the arc-shaped slots 304. The axes of the arc-shaped locking rods 3057 and the arc-shaped slots 304 are both arcs with the second rotating shaft 3055 as the center. A limiting plate 3058 is fixedly installed on the side of the end block 3052 away from the fixed shaft 3051. The limiting plate 3058 is located above the rotating arm 3054. The rotating arm 3054 and the end block 3055 2. Rotary connection, and the axis of the arc-shaped locking rod 3057 on the rotating arm 3054 and the arc-shaped locking groove 304 on the side wall of the tin furnace body 1 are both arcs with the second rotating shaft 3055 as the circle. After the baffle 3021 covers the top of the furnace basin 301, the arc-shaped locking rod 3057 is locked into the arc-shaped locking groove 304, which can lock and fix the tin furnace body 1, furnace basin 301 and baffle 3021 as a whole, ensuring working stability.

[0030] Working principle: When in use, first place the furnace basin 301 into the heating tank 2, put the tin block into the furnace basin 301, and then heat the tin block in the furnace basin 301 through the tin furnace body 1 to melt it, and then solder it through the molten tin.

[0031] During welding, the shielding and protective component 302 is flipped to the top of the furnace basin 301, and then the rotating arm 3054 is rotated downward to the side of the tin furnace body 1. Since the axis of the arc-shaped locking rod 3057 on the rotating arm 3054 and the arc-shaped locking groove 304 on the side wall of the tin furnace body 1 are both arcs with the second rotating shaft 3055 as the circle, the arc-shaped locking rod 3057 can be locked into the arc-shaped locking groove 304, thereby locking and fixing the tin furnace body 1, furnace basin 301 and baffle 3021 as a whole, improving the working stability.

[0032] Because the baffle 3021 with uniformly opened through-hole grooves 3022 is set above the furnace basin 301, it is convenient to weld through-hole components individually. The baffle 3021 is equipped with a guide tube 3024 to raise the solder surface, avoiding the risk of other components falling off during the welding process of through-hole components. It also reduces the time for applying high-temperature tape over a large area, improves the efficiency of tinning operation, and greatly improves the unstable quality and inconsistent solder joints of the previous manual welding. It also reduces the risk of employees being burned during operation, making the operation simple and highly practical.

[0033] After use, rotate the rotating arm 3054 upward to a horizontal position. At this time, the arc-shaped locking rod 3057 disengages from the arc-shaped locking groove 304, and the top wall of the rotating arm 3054 contacts the limiting plate 3058. Then, the baffle 3021 can be rotated upward by the handle 3056, thereby opening the furnace basin 301 to process the remaining molten solder inside.
