Description

Technical Field

[0001] This utility model relates to the field of soldering technology, and in particular to a dual-station laser soldering machine. Background Technology

[0002] A laser soldering machine is a soldering device based on laser technology. It utilizes the precise focusing and energy transfer characteristics of a laser beam to perform soldering operations.

[0003] Its working principle is as follows: based on the precise focusing and energy transfer of the laser beam; the solder pad area is irradiated by the precisely focused laser beam spot, and the solder area heats up rapidly after absorbing the laser energy, causing the solder to melt; then, the laser irradiation is stopped to allow the solder area to cool down, the solder solidifies, and a solder joint is formed.

[0004] Soldering is an important step in the electronics manufacturing industry, especially in the process of PCB assembly; it involves precisely applying liquid or solid solder to specific areas of the PCB to complete the connection between circuits.

[0005] Most existing dual-station soldering machines perform soldering on two parts simultaneously, making it impossible to perform both spot soldering and soldering on electronic products (such as circuit boards) at the same time. If a device could perform both spot soldering and soldering simultaneously, its work efficiency could be effectively improved. Therefore, a dual-station laser soldering machine is needed.

[0006] Chinese Patent Publication No. CN221538376U discloses a dual-station laser soldering machine, including a base plate. The top surface of the base plate is provided with a soldering mechanism and a soldering mechanism. Two side plates are also fixed to the top surface of the base plate. The outer sides of the two side plates are opened into a sliding groove. The sliding groove includes two horizontal sections and a V-shaped section. Four rotating shafts are rotatably connected between the two side plates. Two transmission belts are also provided between the two side plates. Four transmission wheels are frictionally driven on the inner side of the transmission belts. The inner sides of the four transmission wheels are coaxially fixedly connected to the outer sides of the four rotating shafts. A first motor is fixed to the outer side of one of the side plates. One end of the first motor is coaxially fixedly connected to one end of the rotating shaft.

[0007] The above implementation still has the following shortcomings:

[0008] The aforementioned patent uses a transmission belt to enable the device to perform tinning and soldering, and then alternates between them. Although this can perform tinning and soldering, the aforementioned patent cannot effectively fix the processing equipment, and tinning and soldering cannot work simultaneously, reducing the integrity of the device.

Detailed Implementation

[0029] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0030] Example 1

[0031] like Figure 1 and Figure 2 As shown, this embodiment provides a dual-station laser soldering machine, including a base 1, a housing 2 fixedly connected to the upper end of the base 1, a slide rail structure 5 fixedly connected to the left and right sides of the upper middle part of the base 1, a tinning device 3 and a soldering device 4 slidably connected to the left and right sides of the upper outer surface of the slide rail structure 5 respectively, a sliding door mechanism 6 fixedly connected to the front edge of the upper end of the base 1 and the front edge of the top wall of the housing 2, and a placement device 7 fixedly connected to the middle of the upper end of the base 1.

[0032] This device is suitable for tinning and soldering on circuit boards, and it can also be powered by industrial electricity.

[0033] In use, the sliding door mechanism 6 must be opened manually first by sliding it in the opposite direction. After opening the sliding door mechanism 6, place the circuit board on the placement device 7, and then fix the circuit board by controlling the switch. After fixing, close the sliding door mechanism 6, and then control the outer surface of the outer surface of the slide rail structure 5 to apply solder to the circuit board on the left. After the soldering is completed, control the soldering device 3 to apply solder to the circuit board on the right. At the same time as the right circuit board is soldered, the soldering device 4 solders the circuit board on the left that has been soldered, realizing the work of soldering and soldering at the same time. After the soldering device 3 has finished soldering the circuit board on the right, it continues to move to the right to give the soldering device 4 enough space to solder the circuit board on the right. After the work is completed, open the sliding door mechanism 6, take out the completed circuit board and put on a new circuit board for work.

[0034] Furthermore, the soldering device 3 is a soldering machine, which in this solution can move up and down, apply solder, and move left and right on the upper outer surface of the slide rail structure 5. Its specific movement and soldering process are existing technologies, and will not be described in detail here.

[0035] The soldering device 4 is a soldering machine, which in this solution can move up and down, solder, and move left and right on the upper outer surface of the slide rail structure 5. Its specific movement and soldering process are existing technologies and will not be described in detail here.

[0036] Furthermore, the process of the movement trajectory of the placement device 7 can be found in [reference needed]. Figure 3 The placement device 7 includes an outer frame 71, which is fixedly connected to the upper middle part of the base 1. A flat plate 72 is fixedly connected to the upper part of the four walls of the outer frame 71. The flat plate 72 is divided into two areas, left and right. Each area has rectangular holes on the upper left, middle and right sides. The upper left and right sides of the two flat plates 72 are slidably connected to clamping mechanisms 73. The upper parts of the two clamping mechanisms 73 slide on the inner surface of the rectangular holes on the same side of the area.

[0037] In this embodiment, the clamping mechanism 73 can be fixed and moved by controlling it. It moves on the inner surface of the flat plate 72. The specific moving and fixing processes are described below.

[0038] Specifically, to enable the clamping mechanism 73 to move within the rectangular hole of the planar plate 72, refer to... Figure 4The clamping mechanism 73 includes a placement plate 731, which slides on the upper end of the flat plate 72. Clamping plates 732 are slidably connected to the front and rear middle sides of the upper end of the placement plate 731. Support bars 734 are fixedly connected to the middle of the lower end of the two clamping plates 732. Connecting columns 733 are fixedly connected to the four corners of the lower end of the placement plate 731. A sliding plate 737 is fixedly connected to the lower end of the four connecting columns 733. A threaded rod 735 is threadedly connected to the inner surface of the middle part of the sliding plate 737. A rotating motor 739 is fixedly connected to the rear end of the threaded rod 735. Sliding columns 736 are slidably connected to the inner surfaces of the left and right parts of the sliding plate 737. A telescopic mechanism 738 is installed on the upper end of the sliding plate 737.

[0039] Two sliding columns 736 are fixedly connected to the left and right sides of the left side of the outer frame 71, respectively. The front end of the threaded rod 735 is rotatably connected to the middle of the front wall of the outer frame 71. The rotating motor 739 is fixedly connected to the middle of the rear side of the bottom wall of the outer frame 71. Rectangular holes are opened at the front and rear middle sides of the upper end of the placement plate 731. Two support bars 734 slide on the inner surfaces of the rectangular holes opened at the front and right sides of the two placement plates 731 and the middle of the flat plate 72, respectively. The connecting column 733 located on the same side slides on the inner surfaces of the rectangular holes opened at the left and right sides of the upper end of the flat plate 72, respectively.

[0040] The rotating motor 739 is started by controlling the rotation. The rotating motor 739 then drives the threaded rod 735 to rotate through the coupling. The threaded rod 735 then slides on the outer surface of the sliding column 736 through the threaded connection with the sliding plate 737. When the sliding plate 737 slides, it drives the placement plate 731 to slide on the upper end of the flat plate 72 through the connecting column 733, so that it moves forward to place the circuit board when it needs to be placed. After the placement is completed, the rotating motor 739 is controlled to rotate in the opposite direction to align it with the lower part of the soldering device 3.

[0041] This design allows for direct control to move the clamping mechanism 73. Moving the clamping mechanism 73 forward allows for better placement of the circuit board. After placement, it can be moved backward to the lower part of the soldering device 3. During operation, the position of the circuit board placed on the upper part can be adjusted by micro-motion back and forth, allowing it to be soldered at different locations, thus improving its integrity.

[0042] Example 2

[0043] Specifically, in order to achieve the purpose of placing the circuit board on the top of the mounting plate 731 and then fixing it, please refer to... Figure 4 and Figure 5The telescopic mechanism 738 includes a rotating plate 7386, which is rotatably connected to the upper middle part of the sliding plate 737. Arc-shaped plates 7381 are rotatably connected to the upper left and right parts of the rotating plate 7386. Connecting plates 7382 are fixedly connected to the lower parts of the two arc-shaped plates 7381 that are far apart from each other. Convex blocks 7383 are slidably connected to the lower left and right parts of the two connecting plates 7382. A rectangular block 7385 is fixedly connected to the lower right edge of the connecting plate 7382 located at the rear. An electric cylinder 7384 is fixedly connected to the front middle part of the rectangular block 7385.

[0044] Two convex blocks 7383 located on the same side are fixedly connected to the front and rear of the upper end of the sliding plate 737, respectively. The electric cylinder 7384 is fixedly connected to the rear left side of the upper end of the sliding plate 737, and two support bars 734 are fixedly connected to the middle of the upper end of the two connecting plates 7382, respectively.

[0045] By controlling the electric cylinder 7384 to extend and retract forward, the electric cylinder 7384 drives the rectangular block 7385 to move forward. As the rectangular block 7385 moves forward, it sequentially drives the connecting plate 7382 to move above the convex block 7383 with which it is slidably connected. The movement of the connecting plate 7382 drives it to move towards the connected arc-shaped plate 7381. When the arc-shaped plate 7381 moves, it drives the rotating plate 7386 to rotate at the middle of the upper end of the sliding plate 737 through its rotatable connection with the rotating plate 7386. When plate 7386 rotates, it will sequentially drive the left arc plate 7381 to move. The left arc plate 7381 then drives the connecting plate 7382 connected to it to move on the upper end of the convex block 7383. The movement of the two connecting plates 7382 will then drive the support bars 734 connected to them to move. The support bars 734 will then drive the clamping plates 732 connected to them to move. When the electric cylinder 7384 extends and retracts, the clamping plates 732 move to the side that is closer to each other and are fixedly placed on the circuit board on the upper end of the placement plate 731.

[0046] Furthermore, silicone pads are glued to the ends of the two clamps 732 that are close to each other, so that the contact surfaces will not be damaged when the circuit board is fixed, thus ensuring the safety and integrity of the circuit board.

[0047] To achieve the purpose of opening and closing the sliding door mechanism 6, please refer to... Figure 6 The sliding door mechanism 6 includes four concave strips 61. Two concave strips 61 located on the same side are fixedly connected to the left and right parts of the upper front edge of the base 1 and the upper front edge of the top wall of the outer shell 2, respectively. The concave strips 61 located on the same side are slidably connected to a sliding door 62 at their close ends. Pull rods 63 are fixedly connected to the front ends of the two sliding doors 62 on their close ends.

[0048] When the sliding door mechanism 6 needs to be opened, simply pull the lever 63. The lever 63 will then drive the connected sliding door 62 to move at the upper end of the concave strip 61. Limits are provided at the left and right edges of the concave strip 61 to ensure that the sliding door 62 will not slide out or be excessively displaced.

[0049] Furthermore, a magnet positive pole is installed at the middle of the right end of the left sliding door 62, and a magnet negative pole is installed at the middle of the left end of the right sliding door 62, so that it can be fixed when closed.

[0050] It should be noted that the specific installation method, circuit connection method, and control method of the electric cylinder 7384 and the rotary motor 739 used in this utility model are all conventional designs, and will not be described in detail in this utility model.

[0051] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
