[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example: A clamping terminal welding forming device, such as Figure 1 As shown, the terminals and wires are connected by welding, the terminals are assembled, and the crimped terminals are securely connected to the wires.

[0022] according to Figures 1-4 As shown, the welding forming device includes a base 1, on which symmetrically distributed support plates 11 are fixed. The top of the support plates 11 is provided with a horizontal plate 2 and a horizontal plate 3, and the upper surfaces of the horizontal plate 2 and the horizontal plate 3 are located on the same plane.

[0023] A support frame 4 is provided on the base 1 and on the side of the support plate 11. The support frame 4 is located on one side of the horizontal plate 1 2 and the horizontal plate 2 3, and a transmission line assembly 6 is fixedly provided on the other side of the horizontal plate 1 2 and the horizontal plate 2 3.

[0024] A collection box 12 is fixedly installed above the base 1, and a guide groove 13 is fixedly installed above the collection box 12 for feeding finished crimped terminals into the collection box 12, thereby quickly collecting the crimped terminals welded between the horizontal plate 1 2 and the horizontal plate 2 3.

[0025] like Figure 5 , Figure 6 As shown, the horizontal plate 2 includes a platform 21, on which a fixture 22 is fixedly mounted. A horizontal groove is provided below the fixture 22 for guiding and feeding the clamping terminals.

[0026] A cylinder 23 is fixedly installed on the top of the horizontal plate 2. The cylinder 23 is located at one end of the horizontal groove and pushes the clamping terminal sent up from below the horizontal plate 2 into the horizontal groove, and gradually sends it along the horizontal groove between the horizontal plate 2 and the horizontal plate 3.

[0027] A storage rack 24 is fixedly connected below the horizontal plate 2. A vertical groove 25 is provided in the middle of the storage rack 24. The vertical groove 25 extends upward through the horizontal plate 2 to connect with the horizontal groove. A vertical guide groove 29 is provided on the inner side of the vertical groove 25. A shaft 26 is rotatably provided inside the storage rack 24 and on both sides of the two vertical grooves 25. A transmission gear 27 is fixed at the end of the shaft 26. Two adjacent transmission gears 27 mesh to transmit power, so that the two shafts 26 rotate synchronously in opposite directions.

[0028] A motor 28 is fixedly connected to one end of a shaft 26 away from the transmission gear 27. The motor 28 is fixed to the outside of the storage rack 24 by bolts, and the output shaft of the motor 28 is connected to the shaft 26 to drive the shaft 26 to rotate.

[0029] Two take-up rollers are mounted on the shaft 26, and a transmission belt 20 is wound around the take-up rollers. A material tray 200 is fixedly installed on the transmission belt 20. Guide blocks 201 are provided on both sides of the material tray 200. The guide blocks 201 are slidably connected to the vertical guide groove 29. The height of the material tray 200 is changed by winding the two ends of the two transmission belts 20 through the two take-up rollers. This pushes the terminal located at the top of the material tray 200 into the horizontal groove, so that the cylinder 23 can move the terminal.

[0030] like Figure 7 , Figure 8 , Figure 9 , Figure 10As shown, the horizontal plate 2 3 includes a platform 2 31, an opening slot 32 is provided on the platform 2 31, and a cylinder 2 33 is fixedly provided on the platform 2 31. A connecting block 370 is fixedly connected to the output end of the cylinder 2 33. A pressure block 37 is fixedly provided on the side of the connecting block 370. A pressing groove 39 is provided at the end of the pressure block 37 away from the connecting block 370 for pressing the terminal so that the terminal is connected to the wire.

[0031] The pressure block 37 has a welding positioning groove 38.

[0032] Furthermore, the middle of the pressure block 37 is provided with a positioning groove 371, and two support seats 34 are fixedly provided on the second table 31. The support seats 34 are symmetrically arranged on both sides of the opening groove 32. The support seats 34 are provided with a support groove 36, which supports and limits the pressure block 37 to prevent the pressure block 37 from moving down too much, reduce the distance with the T-shaped block 5, and assist in supporting the pressure block 37. In addition, a position sensor 35 is provided above the support seat 34 to monitor whether the pressure block 37 enters or leaves the support seat 34 to determine whether there is processing at the work station.

[0033] Two parallel sliding rods 331 are fixedly connected below the connecting block 370. A spring 332 is fixed between the two sliding rods 331. The spring 332 is connected to the lower end of the connecting block 370 and one end of the T-shaped block 5. The bottom ends of the two sliding rods 331 are connected by an arc-shaped rod 333, which is located below the T-shaped block 5.

[0034] A horizontal shaft 320 is fixedly installed in the opening groove 32, and a positioning rod 341 is fixedly installed between the two support seats 34. The positioning rod 341 cooperates with the positioning groove 371 to position the pressure block 37 and keep it horizontal.

[0035] A T-shaped block 5 is rotatably installed inside the opening slot 32. A partition 54 is fixedly provided at one end of the T-shaped block 5. Through slots 55 are provided on both sides of the partition 54. The through slots 55 are movably connected to the slide rod 331, and the spring 332 is connected above the partition 54. The T-shaped block 5 rotates as follows: Figure 10 As shown in the horizontal position, the positioning rod 341 limits the T-shaped block 5 to keep it horizontal. The other end of the T-shaped block 5 is provided with a jig groove for supporting the terminal to be assembled.

[0036] Furthermore, one end of the fixture groove of the T-shaped block 5 is provided with an inclined surface 52, and an arc-shaped block 51 is slidably provided on the inclined surface 52. The arc-shaped block 51 passes through the T-shaped block 5, and a micro cylinder 50 is fixedly installed below the T-shaped block 5. The output end of the micro cylinder 50 is fixedly connected to the arc-shaped block 51 and is used to push the arc-shaped block 51 to move.

[0037] When the top of the arc-shaped block 51 is flush with the upper surface of the T-shaped block 5, the end of the terminal to be assembled is fixed to support the position of the terminal to be assembled, which facilitates the wiring operation. When the arc-shaped block 51 is pushed upward by the micro cylinder 50, the terminal is fixed between the arc-shaped block 51 and the pressure block 37, and the tail end of the terminal extends out and is located above the inclined surface 52, which facilitates the subsequent bending operation.

[0038] like Figure 11 As shown, a cylinder 40 is fixedly mounted on the support frame 4. A mounting plate 41 is fixedly connected to the output end of the cylinder 40. A welding head 45 is fixedly connected to the lower part of the mounting plate 41. A distance sensor 46 is fixedly mounted at the front end of the mounting plate 41, and a connecting plate 42 is provided at its rear end. The connecting plate 42 is parallel to the inclined plane 52. A cylinder 43 is fixedly mounted on the connecting plate 42. A bending head 44 is installed at the output end of the cylinder 43. The bending head 44 bends the protruding terminal tail end to meet the required bending requirements.

[0039] Furthermore, after the welding head 45 passes through the welding positioning groove 38, it welds the terminal and the wiring position to connect and fix the crimped terminal and the end of the wire.

[0040] like Figure 12 , Figure 13 As shown, a pneumatic clamp 61 is fixedly installed on the wire feeding assembly 6 to temporarily fix the wire. An electric slide table 62 is fixedly installed below the wire feeding assembly 6. A movable frame 63 is slidably installed on the electric slide table 62. A cylinder 64 is installed on the outside of the movable frame 63. A semi-circular cutter 65 is fixedly installed at the output end of the cylinder 64. A stripping knife 66 is fixedly installed on one side of the semi-circular cutter 65. The outer sheath of the wire is cut by the semi-circular cutter 65, and the insulation layer of the wire is peeled off by the stripping knife 66. The electric slide table 62 is used to control the movement of the cutter to remove the insulation layer at the end of the wire.

[0041] When using: Move the terminal onto the T-block 5. At this time, the gap between the pressure block 37 and the T-block 5 allows for feeding. The insulation layer at the end of the wire is removed by the semi-circular cutter 65 and the stripper 66. The metal wire with the insulation removed is then inserted into the crimped terminal. Then, control the output of the second cylinder 33 to move the pressure block 37 further down to complete the crimping of the terminal and the wire. At this time, the welding head 45 can be controlled to move down to weld the connection position and lock the terminal and the wire.

[0042] Then, the wire is cut by an external wire cutter located between the wire transmission assembly 6 and the base 1, which is existing technology.

[0043] After welding is completed, the welding head 45 is reset, and then the pressure block 37 is moved upward by the cylinder 33. The end of the T-shaped block 5 is pushed up by the arc rod 333, so that the other end of the T-shaped block 5 rotates downward, so that the welded terminal slides off the T-shaped block 5 and falls into the guide groove 13 until it enters the collection box 12.

[0044] Finally, the cylinder 33 controls the pressure block 37 to move down, and the spring 332 presses down on the end of the T-shaped block 5, so that the T-shaped block 5 returns to the horizontal state, and then subsequent feeding, pressing, welding and other operations can be carried out.

[0045] When bending of the terminal tail is required, after the pressure block 37 clamps the terminal, the micro cylinder 50 pushes the arc top block 51 upward, raising the terminal tail above the inclined surface 52. After welding is completed, the cylinder 40 drives the mounting plate 41 downward. If the distance sensor 46 detects the correct position, the welding head 45 starts and completes the welding operation. At the same time, the cylinder 43 drives the bending pressure head 44 to slowly extend, bending the extended terminal tail to the set angle along the inclined surface 52. After the required terminal bending is completed, all components quickly reset. The bent terminal is unloaded as the T-shaped block 5 rotates, meeting customized processing requirements. Throughout the entire processing, the actions of each station coordinate with each other. From terminal loading, wire stripping, terminal clamping, welding to bending and unloading, the entire process is completed automatically without manual intervention, effectively improving the accuracy and production efficiency of the clamping terminal and wire connection processing.

[0046] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
