Description

Technical Field

[0001] The utility model relates to the field of automatic terminal welding, in particular to a circuit board terminal welding machine. Background Art

[0002] With the rapid development of electronic technology, circuit boards, as an indispensable component of electronic devices, carry the crucial tasks of circuit connection, signal transmission, and functional realization. The terminals on a circuit board serve as interfaces for connecting external components or circuits, and the quality of their welding directly impacts the performance and reliability of the entire electronic product. As key equipment in automated production lines, welding machines achieve efficient and stable connections between terminals and circuit boards through precise control of the welding process. They are widely used in a variety of fields, including consumer electronics, automotive electronics, and communications equipment.

[0003] Semi-automated production methods are currently common for soldering circuit board terminals. First, workers manually insert the terminals precisely into the pre-set holes on the circuit board, ensuring proper alignment. Subsequently, a special box is placed over the board with the inserted terminals to secure the terminals and prevent them from shifting during subsequent operations. Next, the encapsulated board is flipped over and placed on a workbench, ready for soldering. At this point, a pre-programmed soldering machine uses a torch to solder the contact points between the terminals and the circuit board according to the set soldering path, melting the solder and firmly connecting the two. Once soldering is complete, the box is opened and the circuit board is removed for subsequent inspection and assembly.

[0004] While the above method achieves a certain degree of automation in terminal welding, it still has several drawbacks. First, the welding machine must maintain a constant high temperature throughout the entire operation cycle to ensure it is ready for welding at any time, while the actual welding time is relatively short, resulting in significant energy waste and unnecessary equipment wear. Second, the manual process of inserting the terminals and aligning them with the circuit board's blanks is time-consuming, resulting in low production efficiency. Frequent manual operations are detrimental to the long-term stable operation of the production line. Utility Model Content

DETAILED DESCRIPTION

[0021] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely illustrative and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0022] It should be noted that like reference numerals denote like items in the following drawings, and thus, once an item is defined in one drawing, it may not be further defined or explained in subsequent drawings.

[0023] This embodiment mainly describes the structure of the welding machine, which is as follows:

[0024] A circuit board terminal welding machine, such as Figures 1-4As shown, it includes a base 1, a turntable 2, a ring gear 3, a mounting frame 4, a servo motor 5, a gear 6, a welding machine 7, an operating table 10 and a pressing component. The turntable 2 is rotatably connected to the base 1, and the bottom of the turntable 2 is provided with a ring gear 3. A plurality of slots 8 are provided on the top of the turntable 2, and a plurality of placement holes 9 are provided in each slot 8. A welding machine 7 is installed on the rear side of the base 1, and the welding machine 7 does not contact the turntable 2. A servo motor 5 is installed on the side of the base 1, and the servo motor 5 is connected to the gear 6, and the gear 6 is meshed with the ring gear 3. The front end of the base 1 is connected to the operating table 10. A pressing component for pressing the circuit board is provided on the top side of the base 1. The staff puts the terminals to be welded upside down in the placement holes 9. After the placement holes 9 in a slot 8 are filled, the circuit board is put in, and the hole positions of the circuit board are aligned with the positions where the terminals are placed, and the whole is buckled into the slot 8. The servo motor 5 is turned on. The gear 6 drives the ring gear 3, thereby driving the turntable 2 to rotate, and the ring gear 3 rotates 90 degrees each time. When the circuit board moves to the bottom of the welding machine 7, the welding machine 7 accurately solders the contact points between the terminal and the circuit board according to the preset program. After welding is completed, the servo motor 5 drives the turntable 2 to continue rotating, and the staff removes the circuit board with completed terminal welding from the slot 8. Since there are four slots 8 on the turntable 2, the staff can complete the connection between the terminal and the circuit board when the welding machine 7 is working, thereby saving the waiting time in the middle. The four slots 8 are divided into four areas, namely the connection area between the terminal and the circuit board, the welding area, the material taking area, and the pressing area for the middle pressing component. The outer end of the slot 8 is provided with an arc-shaped groove 15, which is slightly lower than the slot 8, so that the staff can directly reach into the bottom of the circuit board when taking the material and easily take out the circuit board.

[0025] like Figure 1 and Figure 4 As shown, the pressing assembly includes a support frame 11, a guide rod 12, a rubber roller frame 13 and a reset spring 14. The support frame 11 is connected to the top of the base 1. The guide rod 12 is slidably connected to the support frame 11. The bottom of the guide rod 12 is connected to the rubber roller frame 13. A reset spring 14 is sleeved on the guide rod 12. One end of the reset spring 14 is connected to the support frame 11, and the other end is connected to the rubber roller frame 13. After the circuit board is placed in the slot 8 and passes through the bottom of the rubber roller frame 13, the rubber roller frame 13 contacts the circuit board, thereby compressing the reset spring 14. The rubber roller frame 13 pushes the guide rod 12 to slide on the support frame 11. The downward pressure of the rubber roller frame 13 is used to ensure a stable connection between the circuit board and the terminal.

[0026] like Figure 1 As shown, a soft pad 16 is also included. The card slot 8 is covered with a soft pad 16. The soft pad 16 can cushion the bottom of the circuit board when the rubber roller frame 13 presses, and cooperates with the rubber roller on the rubber roller frame 13 to prevent damage to the circuit board.

[0027] like Figure 1As shown, it also includes a baffle 17 and a placement box 20. The placement box 20 is connected to the operating table 10, and an arc-shaped baffle 17 is connected to the rear end of the operating table 10. The placement box 20 is used to place terminals. The baffle 17 can prevent the terminals from falling toward the gear ring 3, affecting the rotation of the gear ring 3.

[0028] like Figure 1 As shown, it also includes a protective shell 19. The outer ring of the base 1 is provided with a protective shell 19 for covering the gear 6 and the ring gear 3. The protective shell 19 also protects the gear 6 and the ring gear 3 to prevent external interference and ensure the stability of the turntable 2 movement.

[0029] like Figure 1 As shown, a bench 18 is also included. The front end of the base 1 is provided with the bench 18. The bench 18 is located in front of the operating table 10. The bench 18 at the front end of the base 1 provides a comfortable operating environment for the staff.

[0030] The staff prepares the terminals and circuit boards to be soldered on the operating table 10. The terminals are placed in the placement box 20 connected to the operating table 10, and the circuit boards are then prepared to be assembled with the placed terminals. The staff puts the terminals to be soldered upside down in the placement holes 9. After the placement holes 9 in a card slot 8 are filled, the circuit board is aligned with the terminal position and snapped into the card slot 8 as a whole. The card slot 8 is covered with a soft pad 16 to protect the circuit board from damage. The servo motor 5 is then turned on, and the gear ring 3 is driven to rotate through the gear 6 connected to it, thereby driving the turntable 2 to rotate. The engagement of the gear ring 3 and the gear 6 ensures the stability and accuracy of the rotation. The turntable 2 is designed to rotate every Rotate 90 degrees again, so that the circuit board in the slot 8 will pass through the connection area, pressing area, welding area and material removal area in sequence. When the circuit board passes the pressing area, the rubber roller frame 13 contacts the circuit board, compresses the reset spring 14 and pushes the guide rod 12 to slide on the support frame 11, thereby applying appropriate downward pressure to ensure a stable connection between the circuit board and the terminal. When the circuit board moves to the bottom of the welding machine 7, the welding machine 7 accurately solders the contact points between the terminal and the circuit board according to the preset program. After the welding is completed, the turntable 2 continues to rotate and brings the circuit board to the material removal area. The staff can easily reach into the bottom of the circuit board through the arc-shaped groove 15 at the outer end of the slot 8 and take it out.
