Detailed Implementation

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0028] In the description of this invention, it should be noted that the orientations or positional relationships indicated by terms such as "center", "up", "down", "left", "right", "vertical", "horizontal", "inner", and "outer" are based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0029] A laser welding device for tube springs, such as Figure 1 and 3 As shown, the device includes a feeding mechanism 1, a material handling gripper mechanism 2, a welding mechanism 3, a pushing gripper mechanism 4, and a supporting mechanism 5. The supporting mechanism 5 includes an extension mechanism 51 and a penetrating cone 52. The extension mechanism 51 is composed of several separated extension blades 511, the front ends of which together form an extension ring 512. The extension mechanism 51 has an inwardly contracting penetrating angle 513 inside. The internal diameter of the extension mechanism 51 in front of the penetrating angle 513 is smaller than that of the extension mechanism 51 behind the penetrating angle 513. The internal diameter of the expansion mechanism 51; the penetrating cone 52 enters the expansion mechanism 51 from behind; a support platform 53 is provided in front of the support mechanism 5, and a pushing mechanism 54 is provided behind the support mechanism 5, which is connected to the penetrating cone 52; a rotating mechanism 55 is provided around the support mechanism 5, which is connected to the expansion mechanism 51; the pushing gripper mechanism 4 is provided in front of the support platform 53; and a sensor 7 is also included, which is located near the support platform 53.

[0030] Specifically, the material handling gripper mechanism 2 takes out the sleeve with the inner spring installed from the feeding mechanism 1 and moves it above the pushing gripper mechanism 4. The sleeve with the inner spring installed is then placed into the pushing gripper mechanism 4 and fixed by it. The pushing gripper mechanism 4 fixes the sleeve with the inner spring installed and moves it towards the support mechanism 5 until the sleeve with the inner spring installed is placed on the support platform 53. The sleeve with the inner spring installed is then placed outside the expansion mechanism 51, while the connection between the edge of the inner spring and the inner surface of the sleeve remains exposed outside the expansion mechanism 51. Subsequently, the pushing gripper mechanism 4 opens, and the pushing mechanism 54 pushes the penetrating cone 52 from behind the expansion mechanism 51 into the interior of the expansion mechanism 51. Because the expansion mechanism 51 has an inwardly contracting penetrating angle 513 inside, the internal space diameter of the expansion mechanism 51 in front of the penetrating angle 513 is smaller than the penetrating angle 513. The internal space diameter of the extension mechanism 51 behind 13 is such that when the penetrating cone 52 enters the internal space of the extension mechanism 51 in front of the penetrating angle 513, the extending blade 511 will expand outwards, driving the extending ring 512 to expand around the center of the ring. This allows the extending ring 512 to press against the inner spring, making the inner spring inside the sleeve more tightly against the inner wall of the sleeve. At this time, the welding mechanism 3 welds the connection between the edge of the inner spring and the inner surface of the sleeve, and the rotating mechanism 55 drives the extension mechanism 51, i.e., the inner spring, to rotate. If the welding is stuck, the sleeve will rotate together until the welding is completed. Each process is sensed by the sensor 7. After welding is completed, the pushing gripper mechanism 4 removes the welded sleeve, and then the material handling gripper mechanism 2 performs the next transport.

[0031] As a preferred embodiment of the above, such as Figure 6 As shown, the pushing gripper mechanism 4 includes a telescopic mechanism 41 and a gripper 42, wherein the gripper 42 is composed of two V-shaped clamping blocks 421 facing the center.

[0032] Specifically, by pushing the gripper mechanism 4, which includes a telescopic mechanism 41 and a gripper 42, the gripper 42 is a structure consisting of two V-shaped clamping blocks 421 facing the center, so that the two V-shaped clamping blocks 421 can better fix the sleeve, and the arc-shaped part of the two V-shaped clamping blocks 421 is adapted to the outer arc of the sleeve.

[0033] As a preferred embodiment of the above, such as Figure 7 As shown, the pushing gripper mechanism 4 is also provided with a sliding column 422 and a spring 423. The V-shaped clamping block 421 is fixed on the sliding column 422, and the spring 423 is disposed between the bottom surface of the V-shaped clamping block 421 and the gripper 42. The spring 423 supports the V-shaped clamping block 421 so that the V-shaped clamping block 421 moves to the middle position of the sliding column 422.

[0034] Specifically, the clamping mechanism 4 is equipped with a sliding column 422 and a spring 423. The V-shaped clamping block 421 is fixed on the sliding column 422, and the spring 423 is located between the bottom surface of the V-shaped clamping block 421 and the clamping jaw 42. The spring 423 supports the V-shaped clamping block 421 so that the V-shaped clamping block 421 moves to the middle position of the sliding column 422. When the clamping jaw 42 clamps the sleeve and moves towards the support platform 53, the spring 423 supports the V-shaped clamping block 421 so that the V-shaped clamping block 421 moves to the middle position of the sliding column 422, so that the height of the sleeve is slightly higher than the expected fixed position, thereby ensuring that the sleeve will not be scratched when it enters the welding position.

[0035] As a preferred embodiment of the above, as shown in 4, a pressing mechanism 6 is also provided above the support platform 51. The pressing mechanism 6 includes a vertical drive member 61 and a pressing block 62. The vertical drive member 61 drives the pressing block 62 to move up and down.

[0036] Specifically, a clamping mechanism 6 is also provided above the support platform 51. The clamping mechanism 6 includes a vertical drive member 61 and a clamping block 62. The vertical drive member 61 drives the clamping block 62 to move up and down. After the sleeve enters the welding position at a height slightly higher than the expected fixed position, the vertical drive member 61 drives the clamping block 62 to press the sleeve. Due to the presence of the spring 423 and the sliding column 422, the V-shaped clamp 421 can move downward with the sleeve, thereby ensuring that the sleeve enters the actual welding position while the V-shaped clamp 421 fixes the sleeve. After welding is completed, the V-shaped clamp 421 removes the welded sleeve. At this time, the horizontal position of the arc center point of the V-shaped clamp 421 is higher than the horizontal position of the outer circle center point of the sleeve shell. The clamping force of the V-shaped clamp 421 is greater than the supporting force of the spring 423 on the bottom surface of the V-shaped clamp 421. As a result, when the V-shaped clamp 421 clamps the sleeve, it will automatically find the position of the copper sleeve. After clamping, due to the disappearance of the resistance force, the spring 423 drives the V-shaped clamp 421 to spring up, thereby removing the welded sleeve without friction. This achieves the effect that the sleeve will not be damaged by friction when entering or leaving the welding position before and after welding.

[0037] As a preferred embodiment of the above, such as Figure 1 As shown, the material handling gripper mechanism 2 includes a material handling drive component 21 and a material handling and placement gripper 22.

[0038] Specifically, the material handling gripper mechanism 2 includes a material handling drive 21 and a material handling placement gripper 22, which is used to place and remove the sleeve into the V-shaped clamping block 421, and the material handling drive 21 drives the material handling placement gripper 22 to complete the loading and unloading of the sleeve.

[0039] As a preferred embodiment of the above, such as Figure 8As shown, the welding mechanism 3 includes a laser welding gun 31, a welding rotation adjustment component 32, and a welding position adjustment component 33; the laser welding gun 31 is mounted on the welding rotation adjustment component 32, the welding rotation adjustment component 32 is mounted on the welding position adjustment component 33, and the nozzle of the laser welding gun 31 is adapted to the position of the support platform 53.

[0040] Specifically, the laser welding gun 31 is mounted on the welding rotation adjustment component 32, which is mounted on the welding position adjustment component 33. The structure in which the nozzle of the laser welding gun 31 is adapted to the position of the support platform 53 allows for adjustment of the welding position of the laser welding gun 31 at any time during the internal welding of the inner spring and the sleeve, thereby achieving a better welding effect.

[0041] As a preferred embodiment of the above, such as Figure 5 As shown, the tail end of the extended blade 511 is provided with an inwardly contracting extension angle 5111.

[0042] Specifically, the tail end of the extended blade 511 is provided with an inwardly contracting extension angle 5111, so that when the penetrating cone 52 enters the interior of the extended blade 511, the front end of the penetrating cone 52 will not cause excessive damage to the extended blade 511 due to incorrect entry position.

[0043] As a preferred embodiment of the above, such as Figure 4 As shown, the penetrating cone 52 is also provided with a flat opening 521.

[0044] As a preferred embodiment of the above, such as Figure 4 As shown, the penetrating cone 52 is also provided with an arcuate cone head 522.

[0045] Specifically, the penetrating cone 52 is equipped with a flat end 521 and an arc-shaped cone head 522. The flat end 521 is used in conjunction with a wrench as a fixed fulcrum for subsequent replacement of various parts. The arc-shaped cone head 522 reduces excessive frictional damage during operation.

[0046] Specifically, the system comprises a feeding mechanism, a gripper mechanism, a welding mechanism, a pushing gripper mechanism, and a support mechanism. The support mechanism includes an extension mechanism and a penetrating cone. The extension mechanism is composed of several separated extending blades, the front ends of which together form an extending ring. An inwardly contracting penetrating angle is provided inside the extension mechanism, and the internal diameter of the extension mechanism in front of the penetrating angle is smaller than the internal diameter of the extension mechanism behind the penetrating angle. The penetrating cone enters the extension mechanism from behind. A support platform is provided in front of the support mechanism, and a pushing mechanism is provided behind it, connected to the penetrating cone. A rotating mechanism is provided around the support mechanism, connected to the extension mechanism. The pushing gripper mechanism is located in front of the support platform. The system also includes a sensor located near the support platform. This design solves the problem in the prior art of unstable welding of the inner spring and sleeve, and the potential damage to the sleeve during welding.
