In traditional processing, there is a lack of dedicated spring piece positioning and fixing mechanisms. Manual stacking of A and B spring pieces is prone to alignment deviations, and the spring pieces are prone to displacement due to vibration during the welding process, resulting in insufficient welding position accuracy, incomplete welding, and mis-welding problems. This seriously affects the stability of product quality, results in low production efficiency, and makes it difficult to meet the needs of batch processing. Utility Model Content

A tongue plate is installed inside the second movable seat, and the tongue plate is located on the opposite side of the spot welding head to abut against the spring strip assembly during welding.

[0005] Furthermore, the top of the track plate is provided with a track groove, a clamping reserved hole and a sliding groove, and the track groove, clamping reserved hole and sliding groove are connected to each other.

[0006] Furthermore, the spring strip kit moves intermittently inside the track groove, the clamping plate extends to the upper part of the track plate through the clamping reserved hole, the length of the clamping reserved hole is greater than the stroke length of the clamping plate, and the tongue plate slides inside the slide groove.

[0007] Furthermore, the spot welding module also includes a limiting seat installed on the top of the track plate. The limiting seat has a guide groove inside, which is adapted to the spot welding head. The telescopic end of the spot welding drive cylinder is connected to the spot welding head through the limiting plate.

[0008] Furthermore, both the limiting seat and the limiting plate are components made of insulating material.

[0009] Furthermore, the spring clip clamping module also includes a first base, the surface of which is slidably connected to a first movable seat via a first linear guide rail, the extension end of the lifting drive cylinder is connected to the first movable seat, and the gripper cylinder is mounted on the top of the first movable seat.

[0014] Reference Figure 1-8 This utility model proposes a spring sheet reinforcement spot welding mechanism, including a track plate 1. The top of the track plate 1 is provided with a track groove 11, a clamping reserved hole 12 and a sliding groove 13 that are interconnected. The track groove 11 provides a guide path for the movement of the spring sheet material kit 2, the clamping reserved hole 12 reserves operating space for the fixing action of the spring sheet clamping module 4, and the sliding groove 13 is used to constrain the movement trajectory of the spring sheet limiting module 5. The three work together to ensure the precise coordination of the actions of each module. In order to achieve precise welding of the spring sheet, the rear, bottom and front sides of the track plate 1 are respectively equipped with a spot welding module 3, a spring sheet clamping module 4 and a spring sheet limiting module 5. The three modules cooperate with each other to complete the welding execution, workpiece fixing and limiting functions in the welding process. The spring strip kit 2 is the processing object of this mechanism. It consists of a strip 21, spring A 22 and spring B 23. It is conveyed in an intermittent manner inside the track groove 11. It pauses after moving to the designated welding station and waits for the welding operation to be completed before continuing to move, so as to realize automated continuous processing. The spot welding module 3 is installed at the rear top of the track plate 1 and mainly consists of a spot welding drive cylinder 31, a limit seat 32, a limit plate 33, a spot welding head 34 (the specific structure of the spot welding head 34 and how to perform spot welding are well-known technical contents to those skilled in the art and will not be described in detail here), and a guide groove 35. The limit seat 32 is fixed to the top of the track plate 1, and the guide groove 35 inside it is adapted to the spot welding head 34, providing precise guidance for the up and down movement of the spot welding head 34 and preventing the spot welding head 34 from deviating during the welding process. The cylinder 31 serves as the power source, and its telescopic end is connected to the spot welding head 34 via the limiting plate 33. When welding is required, the piston rod of the spot welding drive cylinder 31 extends, pushing the limiting plate 33 to drive the spot welding head 34 to move downward along the guide groove 35 until it contacts the spring strip kit 2 and completes the welding. After welding, the piston rod retracts, driving the spot welding head 34 to reset. In addition, the limiting seat 32 and the limiting plate 33 are both made of insulating material, which can effectively prevent leakage during the welding process and ensure the safe operation of the mechanism and the welding quality. The spring clip clamping module 4 is used to fix the spring clip strip kit 2 during welding, preventing workpiece displacement from affecting welding accuracy. It is installed at the bottom of the track plate 1 and mainly consists of a first base 41, a first movable seat 42, a lifting drive cylinder 43, a gripper cylinder 44, a clamping plate 45, and a first linear guide rail 46. The surface of the first base 41 is slidably connected to the first movable seat 42 via the first linear guide rail 46. The first linear guide rail 46 provides guidance for the up-and-down movement of the first movable seat 42, ensuring smooth and stable movement. The lifting drive cylinder 43 is installed on the first base 41, and its telescopic end is connected to the first movable seat 42, driving the first movable seat 42 to move up and down along the first linear guide rail 46. The gripper cylinder 44 is fixed to the top of the first movable seat 42, and its clamping end is equipped with a clamping plate 45. The clamping plate 45 is used to directly contact and clamp the spring strip kit 2. When the spring strip kit 2 moves to the welding station, the piston rod of the lifting drive cylinder 43 extends first, pushing the first movable seat 42 to drive the clamping cylinder 44 and the clamping plate 45 to move upward, so that the clamping plate 45 extends through the clamping reserved hole 12 to the upper part of the track plate 1 and approaches the spring strip kit 2. Then the clamping cylinder 44 is activated, driving the two clamping plates 45 to approach each other and clamp the spring strip kit 2. After the welding is completed, the clamping cylinder 44 first drives the clamping plate 45 to release, and the lifting drive cylinder 43 then drives the first movable seat 42 and the clamping plate 45 to return to the lower position. The length of the clamping reserved hole 12 is greater than the stroke length of the clamping plate 45, leaving enough space for the up and down movement of the clamping plate 45 and avoiding the clamping plate 45 from colliding with the track plate 1. The spring clip limiting module 5 is installed on the front side of the track plate 1. It is used to abut against the spring clip material kit 2 from the opposite side of the spot welding head 34 during welding, further improving the stability of the workpiece fixation. It mainly consists of a second base 51, a second movable seat 52, a motor 53, a lead screw 54, a wire drum 55, a tongue plate 56, and a second linear guide rail 57. The second base 51 is fixed on the front side of the track plate 1, and its surface is slidably connected to the second movable seat 52 through the second linear guide rail 57, providing guidance for the back-and-forth movement of the second movable seat 52. The motor 53 is installed on the top of the second base 51, and its drive end is connected to the lead screw 54. The lead screw 54 is externally threaded with the wire drum 55, and the side of the wire drum 55 is connected to the second movable seat 52. The tongue plate 56 is fixedly connected and installed inside the second movable seat 52. The tongue plate 56 is located in the slide groove 13 and can slide with the second movable seat 52 in the slide groove 13. When it is necessary to limit the spring strip kit 2, the motor 53 starts and drives the lead screw 54 to rotate. The lead screw 54 drives the lead screw 55 to move the second movable seat 52 along the second linear guide 57 towards the spring strip kit 2 until the tongue plate 56 abuts against the spring strip kit 2. After welding is completed, the motor 53 reverses and drives the lead screw 54 to rotate in the opposite direction, so that the second movable seat 52 and the tongue plate 56 are reset, releasing the limit on the spring strip kit 2, so that it can continue to move to the next station.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
