Technical Field
[0001] This utility model relates to the field of lead-free wave soldering machine technology, specifically a mixed-flow production lead-free wave soldering machine. Background Technology
[0002] Mixed-flow production lead-free wave soldering machines are welding equipment designed for continuous production of various types and specifications of electronic substrates. They use electric or electromagnetic pumps to drive molten lead-free solder (such as tin-copper alloy) to form solder waves of a specific shape, allowing the PCB board loaded with components to pass through the wave at a specific angle and immersion depth, thus achieving mechanical and electrical connection between the solder ends and the solder pads.
[0003] In actual industrial production, lead-free wave soldering machines in mixed-flow production require material to be fed into the machine during welding. Since most lead-free wave soldering machines do not have a feeding mechanism, they are mostly fed manually. For batch welding, the entire feeding process is time-consuming and labor-intensive, greatly increasing the labor intensity of the workers. Utility Model Content
[0004] The purpose of this invention is to at least solve one of the technical problems existing in the prior art. To this end, this invention proposes a mixed-flow production lead-free wave soldering machine that can automatically and continuously feed materials onto the soldering machine body. The entire feeding process is time-saving and labor-saving, greatly reducing the labor intensity of workers.
[0005] A lead-free wave soldering machine for mixed-flow production according to an embodiment of the present invention includes:
[0006] The welding machine body has a conveyor frame fixedly installed at its inner bottom end.
[0007] The storage box has its back side attached to one side of the conveyor frame, and its front side is fixedly provided with a mounting base.
[0008] The material pushing assembly includes a motor, the bottom end of which is fixedly mounted on the top of a fixed base. The output end of the motor is provided with a rotating shaft, and the bottom end of the rotating shaft is fixedly provided with a first connecting rod. A second connecting rod is rotatably provided on one side of the bottom end of the first connecting rod, and an ear block is rotatably provided on one side of the bottom end of the second connecting rod. A material pushing plate is fixedly provided on one side of the ear block.
[0009] According to some embodiments of the present invention, the outer wall of the pusher plate penetrates the front of the storage box and slides in cooperation with the storage box.
[0010] According to some embodiments of the present invention, connecting seats are fixedly provided on both sides of the storage box, and a support rod is fixedly provided on one side of each of the two connecting seats. The two support rods are respectively fixedly connected to one side of the welding machine body.
[0011] According to some embodiments of the present invention, a discharge port is provided on the back of the storage box, and two rod seats are fixedly provided on the lower part of the back of the storage box near the discharge port. Two guide rods are rotatably provided on the opposite side of the two rod seats.
[0012] According to some embodiments of the present invention, a first fixing groove is provided on both sides of the top of the pusher plate, and a plurality of first rollers are rotatably provided on the inner walls of the two first fixing grooves.
[0013] According to some embodiments of the present invention, the inner bottom end of the storage box is provided with two second fixing grooves, and the inner walls of the two second fixing grooves are rotatably provided with a plurality of second rollers.
[0014] According to some embodiments of the present invention, the top end of the second roller and the top end of the guide rod are located on the same horizontal plane.
[0015] The lead-free wave soldering machine of this utility model has the following beneficial effects:
[0016] Equipped with a motor, a pusher plate, and a storage box, the machine automatically feeds materials onto the welding machine body. When the motor is turned on, it drives the first connecting rod to rotate via a shaft. As the first connecting rod rotates 180 degrees, it drives the pusher plate to move to the left via the second connecting rod, causing the electronic substrate above the pusher plate to fall. When the first connecting rod continues to rotate 360 degrees, it drives the pusher plate to move to the right via the second connecting rod, pushing the electronic substrate at the bottom of the storage box out through the discharge port. This process repeats continuously, automatically feeding materials onto the welding machine body. The entire feeding process is time-saving and labor-saving, significantly reducing the workload of workers. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.
[0026] Please see Figure 1-4 As shown, this utility model is a mixed-flow production lead-free wave soldering machine, comprising:
[0027] The welding machine body 1 has a conveyor frame 2 fixedly installed at the inner bottom end of the welding machine body 1;
[0028] The welding machine body 1 is used for welding electronic substrates, and the conveyor frame 2 is used for transporting electronic substrates.
[0029] The back of the storage box 3 is attached to one side of the conveyor frame 2, and the front of the storage box 3 is fixedly provided with a fixing seat 4.
[0030] The storage box 3 is used to store the electronic substrate to be soldered, and the fixing base 4 is used for connection support;
[0031] The pusher assembly 5 includes a motor 51. The bottom end of the motor 51 is fixedly mounted on the top of the fixed base 4. The output end of the motor 51 is provided with a rotating shaft 52. The bottom end of the rotating shaft 52 is fixedly provided with a first connecting rod 53. A second connecting rod 54 is rotatably provided on one side of the bottom end of the first connecting rod 53. An ear block 55 is rotatably provided on one side of the bottom end of the second connecting rod 54. A pusher plate 56 is fixedly provided on one side of the ear block 55.
[0032] Motor 51 provides the driving force required for the pusher plate 56 to move back and forth. The outer wall of the rotating shaft 52 passes through the top of the fixed seat 4 and rotates with the fixed seat 4. When the first connecting rod 53 rotates to 180 degrees, it drives the pusher plate 56 to move to the left through the second connecting rod 54. When the first connecting rod 53 rotates to 180 degrees, one side of the pusher plate 56 is on the same vertical plane as the inner wall of the storage box 3. When the first connecting rod 53 continues to rotate to 360 degrees, it drives the pusher plate 56 to move to the right.
[0033] The outer wall of the pusher plate 56 penetrates the front of the storage box 3 and slides with the storage box 3;
[0034] The storage box 3 is also used to guide and limit the pusher plate 56, so that it can move horizontally.
[0035] Both sides of the storage box 3 are fixedly provided with connecting seats 6, and one side of each of the two connecting seats 6 is fixedly provided with a support rod 7. The two support rods 7 are respectively fixedly connected to one side of the welding machine body 1.
[0036] The support rod 7 is used to connect and support the feeding mechanism, thereby ensuring its overall stability.
[0037] The back of the storage box 3 has a discharge port 31. Two rod seats 8 are fixedly provided on the back of the storage box 3 near the discharge port 31. Two guide rods 9 are rotatably provided on the opposite side of the two rod seats 8.
[0038] The discharge port 31 is used to unload the electronic substrates from the storage box 3, and the guide rod 9 facilitates the guidance of the electronic substrates to the conveyor frame 2.
[0039] Working principle: The electronic substrate to be welded is placed in the storage box 3. When it is necessary to feed the welding machine body 1, the motor 51 is turned on. The motor 51 drives the first connecting rod 53 to rotate through the rotating shaft 52. When the first connecting rod 53 rotates to 180 degrees, it drives the ear block 55 to move to the left through the second connecting rod 54, which in turn drives the pusher plate 56 to move to the left. At this time, the electronic substrate located above the pusher plate 56 falls to the bottom of the storage box 3. When the first connecting rod 53 continues to rotate to 360 degrees, it drives the pusher plate 56 to move to the right through the second connecting rod 54. The pusher plate 56 pushes the electronic substrate at the bottom of the storage box 3 out of the discharge port 31 and moves it along the guide rod 9 to the conveyor frame 2. This cycle repeats. In this way, the welding machine body 1 can be automatically and continuously fed. The whole feeding process is time-saving and labor-saving, and greatly reduces the labor intensity of the workers.
[0040] Please see Figure 1-4 As shown, this embodiment, based on the above embodiment, further includes:
[0041] The top of the pusher plate 56 has two first fixing grooves 57 on both sides, and the inner walls of the two first fixing grooves 57 are rotatably equipped with several first rollers 58.
[0042] The top of the first roller 58 is slightly higher than the first fixing groove 57.
[0043] The bottom of the storage box 3 has two second fixing grooves 32, and the inner walls of the two second fixing grooves 32 are rotatably equipped with several second rollers 33.
[0044] The top of the second roller 33 is slightly higher than the height of the second fixed groove 32.
[0045] The top of the second roller 33 is on the same horizontal plane as the top of the guide rod 9.
[0046] Working principle: When the electronic substrate in the storage box 3 is above the pusher plate 56, during the feeding process of the pusher plate 56 pushing the electronic substrate at the bottom of the storage box 3, the sliding friction between the pusher plate 56 and the electronic substrate changes to rolling friction under the action of the first roller 58. When the electronic substrate falls to the bottom of the storage box 3, the pusher plate 56 pushes it to feed. Under the action of the second roller 33, the sliding friction between the electronic substrate and the storage box 3 changes to rolling friction. In this way, the friction between the electronic substrate and the storage box 3 can be reduced during the feeding process, which not only facilitates feeding but also reduces wear.
