Description

Technical Field

[0001] This utility model relates to the field of soldering equipment technology, and in particular to an automatic soldering device. Background Technology

[0002] Solder is an important industrial raw material for connecting electronic components in circuits. It is a type of solder with a low melting point, mainly referring to solder made from tin-based alloys. Solder is manufactured by first melting it into ingots, and then pressure processing it into finished products. Solder materials are indispensable in the production and maintenance work of the electronics industry.

[0003] Chinese utility model patent CN218946582U discloses an automatic soldering device. This device includes a base plate and a clamping mechanism on the base plate. A workpiece is placed within the clamping mechanism. Two fixing blocks are mounted on the base plate, and a second adjustment mechanism is mounted on each of the two fixing blocks. The second adjustment mechanism includes a gantry frame positioned between the two fixing blocks, and a first adjustment mechanism is mounted on the gantry frame. The first adjustment mechanism includes a slider, a lifting mechanism on the slider, and a solder gun on the lifting mechanism. A cleaning mechanism is mounted on the base plate corresponding to the solder gun, and a bracket is mounted on the lifting mechanism corresponding to the solder gun. A solder tube is mounted on the bracket via a positioning mechanism. The first adjustment mechanism of this utility model enables the solder gun to perform horizontal soldering on the workpiece, while the second adjustment mechanism enables the solder gun to perform vertical soldering on the workpiece. Thus, the first and second adjustment mechanisms work together to allow soldering of the workpiece without manual adjustment of its position.

[0004] Regarding the aforementioned technologies, the inventors believe that the following defects exist: The above-mentioned device keeps the workpiece stable through the clamping mechanism fixed on the base plate. In actual use, most of the workpieces to be welded are made of metal and are quite heavy. When workers disassemble the workpieces, they are prone to collisions with the soldering gun and other structures above the base plate, which can easily damage the soldering gun and other structures, resulting in a poor user experience. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides an automatic soldering device.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an automatic soldering device, including a base plate, a gantry frame set on the base plate, a lifting mechanism connected to the gantry frame, and a soldering gun installed on the lifting mechanism. Two mutually symmetrical support plates are fixed on the upper surface of the base plate. Slide grooves are provided on the inner bottom walls of the two support plates. Slide rods are slidably arranged in the two slide grooves. A connecting plate is installed on the upper surface of the two slide rods.

[0007] By adopting the above technical solution, when workers need to solder on the welding device, they need to pull the connecting plate, which will cause the slide bar to slide along with the connecting plate, thus moving the connecting plate to the side of the soldering device. At this time, workers only need to place the workpiece on the connecting plate and push the connecting plate to reset it, thereby supporting the workpiece with the support plate. Furthermore, workers only need to rotate the stop lever to block the connecting plate, thus keeping the workpiece stable and reducing the difficulty of disassembling the workpiece.

[0008] Furthermore, the bottom surface of the connecting plate is provided with a rotating groove, the inner wall of the rotating groove is provided with a rotating hole, a rotating rod is rotatably arranged in the rotating hole, and a rotating plate is fixedly arranged on the side wall of the rotating rod.

[0009] Furthermore, a torsion spring is fixed to the side wall of the rotating rod, and the other end of the torsion spring is fixed to the inner wall of the rotating hole.

[0010] By adopting the above technical solution, when the worker pulls the connecting plate, the rotating groove gradually separates from the support plate as the connecting plate moves. This causes the rotating plate to automatically rotate downward under the action of the torsion spring, so that the rotating plate rotates 90 degrees and then presses against the inner wall of the rotating groove. This allows the rotating plate to support one side of the connecting plate, thereby reducing the probability of the connecting plate deforming under the action of the workpiece.

[0011] Furthermore, a first magnet block is embedded in the side wall of the rotating plate, and an electromagnet is embedded in the inner top wall of the rotating groove.

[0012] By adopting the above technical solution, when workers need to weld workpieces, they need to pull the connecting plate to connect the workpiece to the upper surface of the connecting plate. During this process, the rotating plate supports the connecting plate. Subsequently, when workers need to reset the connecting plate, they only need to turn on the electromagnet, which will attract the first magnet block, thereby resetting the rotating plate under the action of the electromagnet and pressing it against the inner top wall of the rotating groove. This eliminates the need for workers to actively rotate the rotating plate, thus reducing the difficulty of operation.

[0013] Furthermore, a second magnet block is embedded in the inner wall of the rotating groove, and the first magnet block and the second magnet block attract each other.

[0014] By adopting the above technical solution, when the rotating plate automatically rotates downwards under the action of the torsion spring, it rotates 90 degrees and then presses against the inner wall of the rotating groove. At this time, the first magnet and the second magnet attract each other, thereby improving the stability of the rotating plate and reducing the probability of the rotating plate angle changing when the connecting plate is subjected to external force, thus improving the user experience of the staff.

[0015] Furthermore, the bottom surface of the rotating plate is provided with a plurality of equally spaced ball bearings.

[0016] By adopting the above technical solution, the ball bearings reduce the friction between the rotating plate and the base plate, thereby further reducing the probability of the rotating plate angle changing when the connecting plate is subjected to external force, and thus improving the stability of the rotating plate.

[0017] Furthermore, a limiting groove is formed on the inner wall of the slide, and a limiting block is slidably arranged in the limiting groove, with the limiting block and the slide rod being fixed to each other.

[0018] By adopting the above technical solution, the limiting groove blocks the limiting block, thereby reducing the probability of the sliding rod and the sliding groove separating when the operator moves the connecting plate, thus improving the operator's user experience.

[0019] Furthermore, a stop bar for blocking the connecting plate is rotatably provided on the side wall of the tray.

[0020] By adopting the above technical solution, after the worker resets the connecting plate, the worker only needs to rotate the stop rod to block the connecting plate, thereby reducing the probability of the connecting plate changing position and improving the stability of the workpiece.

[0021] In summary, this utility model has the following beneficial effects:

[0022] 1. In this application, when a worker needs to solder on a device with a soldering arm, the worker pulls the connecting plate, causing the sliding rod to slide along with the connecting plate, thus moving the connecting plate to the side of the soldering device. At this point, the worker simply places the workpiece on the connecting plate and pushes it to reset the connecting plate, thereby supporting the workpiece with the support plate. Furthermore, the worker can simply rotate the stop lever to block the connecting plate, thus stabilizing the workpiece and reducing the difficulty of disassembling the workpiece.

[0023] 2. In this application, when the worker pulls the connecting plate, as the connecting plate moves, the rotating groove gradually separates from the support plate, and the rotating plate automatically rotates downward under the action of the torsion spring. After the rotating plate rotates 90 degrees, it presses against the inner wall of the rotating groove, thereby supporting one side of the connecting plate and reducing the probability of the connecting plate deforming under the action of the workpiece.

[0024] 3. In this application, when the worker needs to weld the workpiece, the worker needs to pull the connecting plate to connect the workpiece with the upper surface of the connecting plate. During this process, the rotating plate supports the connecting plate. Subsequently, the worker needs to reset the connecting plate. At this time, the worker only needs to turn on the electromagnet, which will attract the first magnet block, thereby resetting the rotating plate under the action of the electromagnet, and then pressing the rotating plate against the inner top wall of the rotating groove. The worker does not need to actively rotate the rotating plate, thus reducing the difficulty of operation. Attached Figure Description

Detailed Implementation

[0031] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0032] like Figure 1-5As shown in the embodiment of this application, an automatic soldering device is disclosed, including a base plate 1, a gantry frame 11, a lifting mechanism 2, a soldering gun 21, a support plate 3, a slide rod 4, a connecting plate 41, a rotating rod 6, a rotating plate 61, a torsion spring 7, a first magnet 71, an electromagnet 8, a second magnet 81, a ball bearing 82, a limiting block 84, and a stop bar 9. The gantry frame 11 is mounted on the base plate 1, and the lifting mechanism 2 is connected to the gantry frame 11. The soldering gun 21 is mounted on the lifting mechanism 2. Two support plates 3 are provided and symmetrically arranged on the upper surface of the base plate 1. Each of the inner bottom walls of the two support plates 3 has a sliding groove 31. The slide rod 4 is a rectangular rod-shaped structure, and two slide rods 4 are provided and slidably arranged in the two sliding grooves 31 respectively. The connecting plate 41 is a rectangular plate-shaped structure, and the connecting plate 41 is mounted on the upper surface of the two slide rods 4.

[0033] The bottom surface of the connecting plate 41 has a rotating groove 5, and the inner wall of the rotating groove 5 has a rotating hole 51. The rotating rod 6 is a round rod structure and is rotatably disposed in the rotating hole 51. The rotating plate 61 is a rectangular plate structure and is fixedly disposed on the side wall of the rotating rod 6. One end of the torsion spring 7 is fixed to the side wall of the rotating rod 6, and the other end of the torsion spring 7 is fixed to the inner wall of the rotating hole 51.

[0034] When the operator pulls the connecting plate 41, as the connecting plate 41 moves, the rotating groove 5 gradually separates from the support plate 3, and then the rotating plate 61 automatically rotates downward under the action of the torsion spring 7. After the rotating plate 61 rotates 90 degrees, it presses against the inner wall of the rotating groove 5, thereby supporting one side of the connecting plate 41 and reducing the probability of the connecting plate 41 deforming under the action of the workpiece.

[0035] The first magnet block 71 has a block structure and is embedded in the side wall of the rotating plate 61. The electromagnet 8 is embedded in the inner top wall of the rotating groove 5.

[0036] When welding a workpiece, the operator pulls the connecting plate 41 to connect the workpiece to the upper surface of the connecting plate 41. During this process, the rotating plate 61 supports the connecting plate 41. Subsequently, the operator needs to reset the connecting plate 41. At this time, the operator only needs to turn on the electromagnet 8, which will attract the first magnet block 71, thereby resetting the rotating plate 61 under the action of the electromagnet 8. This allows the rotating plate 61 to press against the inner top wall of the rotating groove 5, eliminating the need for the operator to actively rotate the rotating plate 61, thus reducing the difficulty of operation.

[0037] The second magnet 81 has a block-shaped structure and is embedded in the inner wall of the rotating groove 5. The first magnet 71 and the second magnet 81 are attracted to each other. When the rotating plate 61 automatically rotates downward under the action of the torsion spring 7, the rotating plate 61 rotates 90 degrees and then presses against the inner wall of the rotating groove 5. At this time, the first magnet 71 and the second magnet 81 are attracted to each other, thereby improving the stability of the rotating plate 61 and reducing the probability of the angle of the rotating plate 61 changing when the connecting plate 41 is subjected to external force, thus improving the user experience of the staff.

[0038] The ball bearings 82 have a spherical structure, and multiple ball bearings 82 are evenly distributed on the bottom surface of the rotating plate 61. The ball bearings 82 reduce the friction between the rotating plate 61 and the base plate 1, thereby further reducing the probability that the angle of the rotating plate 61 will change when the connecting plate 41 is subjected to external force, and thus improving the stability of the rotating plate 61.

[0039] A limiting groove 83 is provided on the inner wall of the slide groove 31. The limiting block 84 is a rectangular block structure. The limiting block 84 is slidably disposed in the limiting groove 83, and the limiting block 84 is fixed to the slide rod 4.

[0040] The limiting groove 83 blocks the limiting block 84, thereby reducing the probability of the slide rod 4 and the slide groove 31 separating when the operator moves the connecting plate 41, thus improving the operator's user experience.

[0041] The stop bar 9 is a rod-shaped structure that is rotatably mounted on the side wall of the support plate 3 to block the connecting plate 41. After the operator resets the connecting plate 41, the operator only needs to rotate the stop bar 9 to block the connecting plate 41, thereby reducing the probability of the connecting plate 41 changing position and improving the stability of the workpiece.

[0042] The operating principle of the automatic soldering device in this embodiment is as follows: When a worker needs to solder the device, the worker pulls the connecting plate 41, causing the sliding rod 4 to slide along with the connecting plate 41, thus moving the connecting plate 41 to the side of the soldering device. At this time, the worker only needs to place the workpiece on the connecting plate 41 and push the connecting plate 41 to reset it, thereby supporting the workpiece with the support plate 3. Furthermore, the worker only needs to rotate the stop rod 9 to block the connecting plate 41, thus keeping the workpiece stable and reducing the difficulty for the worker to disassemble the workpiece.

[0043] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
