Description

Technical Field

[0001] This invention relates to the field of welding equipment, and more particularly to a welding equipment for radiator U-shaped tubes. Background Technology

[0002] Heat sinks are key components in electronic devices used to dissipate heat. Their core function is to prevent overheating of electrical components such as power transistors by providing supplemental cooling. Traditional heat sink designs typically employ a combination of U-shaped tubes and straight tubes to quickly conduct heat to the heat sink body, which is then released to the surrounding environment through fans or natural convection. During the welding process of the U-shaped tubes and straight tubes, due to the large structure of the manually operated welding gun, workers usually need to pull a considerable length of the straight tube out of the heat sink for welding operations. This results in a long length of the straight tube extending out of the heat sink, which not only increases the overall size of the component but also occupies valuable internal space, seriously affecting the requirement for miniaturized heat sink designs. Summary of the Invention

[0003] To overcome the drawbacks of the large structure of manually operated welding guns and the long length of straight pipes extending outward from the inside of the radiator, which affects the miniaturization requirements of radiator design, this invention provides a radiator U-shaped pipe welding device.

[0004] The technical solution is as follows: A radiator U-shaped tube welding device includes a placement platform, a horizontal electric slider, a vertical electric slider, a welding gun body, a C-shaped frame, a C-shaped sliding plate, a C-shaped rack, a motor, gears, a fixing block, welding tungsten needles, and an air jet pipe; the horizontal electric slider is slidably connected to the placement platform; the vertical electric slider is slidably connected to the horizontal electric slider; the welding gun body is connected to the vertical electric slider; the C-shaped frame is connected to the rear side of the welding gun body; the C-shaped sliding plate is slidably connected inside the C-shaped frame; a C-shaped rack is fixedly connected to the C-shaped sliding plate; a motor is installed on the C-shaped frame; the output shaft of the motor is fixedly connected to a gear that drives the C-shaped rack to move; a welding tungsten needle is connected to the inner right side of the C-shaped sliding plate through a fixing block; an air jet pipe is fixedly connected to the C-shaped frame, and the air jet port of the air jet pipe faces the inside of the C-shaped frame.

[0005] Furthermore, an arc-shaped baffle for blocking the local suction hole structure is fixed to the C-shaped slide plate; a telescopic pipe for connecting to the jet pipe is fixed to the arc-shaped baffle; and several jet hole structures for connecting to the telescopic pipe are opened on the arc-shaped baffle.

[0006] Furthermore, the C-shaped frame is fixedly connected to an air extraction pipe; the inner wall of the C-shaped frame has several suction holes that connect to the air extraction pipe.

[0007] Furthermore, the C-shaped sliding plate is fixed with several limiting rods, and the telescopic pipe is clamped between the inner wall of the C-shaped frame and the limiting rods.

[0008] Furthermore, a C-shaped baffle is fixed to the C-shaped slide to cover the gap at the C-shaped frame.

[0009] Furthermore, a laser rangefinder is installed on the welding gun body to automatically detect the position of the annular welding electrode.

[0010] Furthermore, the welding gun body is detachably connected to a longitudinal electric slider via several fixed plug rods.

[0011] Furthermore, the C-shaped frame is slidably connected to the welding gun body; a height adjustment screw is rotatably connected to the welding gun body to adjust the up and down movement of the C-shaped frame; a knob is fixedly connected to the height adjustment screw.

[0012] Furthermore, the fixing block is detachably fixed to the C-shaped sliding plate via a threaded structure.

[0013] Furthermore, a C-shaped top cover is detachably inserted into the C-shaped slide plate, and the C-shaped top cover is designed as an upwardly contracting bucket-shaped structure.

[0014] This invention has the following advantages: The radiator U-shaped tube welding equipment of this invention uses a horizontal electric slider and a vertical electric slider in conjunction with a laser rangefinder to precisely align the C-shaped frame on the welding gun body with the straight pipe on the radiator box. The annular welding rod between the straight pipe and the U-shaped pipe is automatically welded by the sliding C-shaped plate inside the C-shaped frame. The total length of the C-shaped frame is relatively short. Even if the straight pipe protrudes only a short length from the top of the radiator box, the C-shaped frame can still be placed close to the outside of the straight pipe to perform automated welding of the annular welding rod. This not only solves the technical problem that the large structure of the welding gun operated manually and the long length of the straight pipe extending from the inside of the radiator affect the small-volume design requirements of the radiator, but also realizes the automated welding of the annular welding rod between the straight pipe and the U-shaped pipe in the radiator.

Detailed Implementation

[0017] References to embodiments herein mean that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0018] Example 1: A radiator U-tube welding device, such as... Figures 1-7 As shown, the assembly includes a placement platform 1, a horizontal electric slider 2, a vertical electric slider 3, a welding gun body 41, a C-shaped frame 42, a C-shaped sliding plate 43, a C-shaped rack 44, a motor 45, a gear 46, a fixing block 47, a welding tungsten needle 48, an exhaust pipe 51, an exhaust pipe 52, and a laser rangefinder 7. A horizontal electric slider 2, which moves in the left-right direction, is slidably connected to the placement platform 1. A vertical electric slider 3, which moves in the front-back direction, is slidably connected to the horizontal electric slider 2. A welding gun body 41 is connected to the vertical electric slider 3, and the welding gun body 41 is externally connected to the welding host. A C-shaped frame 42 is connected to the rear side of the welding gun body 41. A C-shaped sliding plate 43 is slidably connected inside the C-shaped frame 42. A C-shaped rack 44 is fixedly connected to the C-shaped sliding plate 43. A motor 45 is installed; a gear 46 is fixedly connected to the output shaft of the motor 45; the gear 46 meshes with a C-shaped rack 44; a welding tungsten needle 48 is connected to the inner right side of the C-shaped slide plate 43 via a fixing block 47; a conductive sheet structure is provided on the C-shaped slide plate 43, and the circuit system of the welding gun body 41 is connected to the welding tungsten needle 48 through the conductive sheet structure of the C-shaped slide plate 43; an exhaust pipe 51 is fixedly connected between the welding gun body 41 and the C-shaped frame 42, and an external suction machine is connected to the exhaust pipe 51; several suction holes 4201 connected to the exhaust pipe 51 are opened on the inner wall of the C-shaped frame 42; an air jet pipe 52 is fixedly connected between the welding gun body 41 and the C-shaped frame 42, and an external protective gas delivery device is connected to the air jet pipe 52; a laser rangefinder 7 is installed on the welding gun body 41.

[0019] like Figures 3-6 As shown, an arc-shaped baffle 61 is fixed to the upper and lower sides of the C-shaped slide plate 43, and the arc-shaped baffle 61 initially blocks the suction hole structure 4201 near the fixed block 47; a telescopic pipe 53 connecting to the jet pipe 52 is fixed to the arc-shaped baffle 61; several jet hole structures 6101 connecting to the telescopic pipe 53 are opened on the arc-shaped baffle 61; several limiting rods 431 are fixed to the lower side of the C-shaped slide plate 43, and the telescopic pipe 53 is kept clamped between the inner wall of the C-shaped frame 42 and the limiting rods 431 during movement; a C-shaped baffle 62 is fixed to the upper and lower sides of the C-shaped slide plate 43, and the C-shaped baffle 62 is initially stored in the C-shaped frame 42.

[0020] In this embodiment, the straight pipes 82 used on the heat sink 81 have a shorter exposed length. A U-shaped pipe 83 is inserted between every two adjacent straight pipes 82 on the front and back of the heat sink 81. An annular welding rod 84 is fitted between each end of the U-shaped pipe 83 and a corresponding straight pipe 82. Therefore, the total vertical length of this heat sink, composed of the heat sink 81, straight pipes 82, and U-shaped pipes 83, is shorter than that of a traditional heat sink 81, making it easier to further optimize the design for smaller volumes. After the heat sink housing 81 of this heat sink is placed on the placement platform 1, the horizontal electric slider 2 drives the welding gun body 41 on the vertical electric slider 3 to move from right to left. At the same time, the laser rangefinder 7 on the welding gun body 41 emits a range-measuring laser to measure and position the positions of each straight pipe 82 on the front side of the welding gun body 41, so that the C-shaped frame 42 on the welding gun body 41 can be precisely aligned with each straight pipe 82 on the front side of the heat sink housing 81 in sequence, and the annular welding rod 84 between each straight pipe 82 and the corresponding U-shaped pipe 83 is welded in sequence.

[0021] Whenever the C-shaped bracket 42 on the welding gun body 41 aligns with the annular welding rod 84 between a straight pipe 82 and a U-shaped pipe 83, the longitudinal electric slider 3 drives the welding gun body 41 and the C-shaped bracket 42 to move backward, so that the C-shaped bracket 42 and the C-shaped slide plate 43 surround the outside of the annular welding rod 84, and the welding tungsten needle 48 is close to the right side of the annular welding rod 84. Then, the motor 45 drives the gear 46 to rotate, and the gear 46 meshes with the C-shaped rack 44 to drive the C-shaped slide plate 43 to rotate one revolution along the C-shaped bracket 42. The C-shaped slide plate 43 drives the welding tungsten needle 48 to rotate one revolution around the annular welding rod 84. The annular welding rod 84 is thermally welded between the straight pipe 82 and the U-shaped pipe 83 by the welding tungsten needle 48. Since the total length of the C-shaped bracket 42 is relatively short, even if the straight pipe 82 protrudes only a short length from the top of the heat sink 81, the C-shaped bracket 42 can still fit and be placed on the outside of the straight pipe 82 to perform automated welding of the annular welding rod 84.

[0022] During the welding process, as the C-shaped sliding plate 43 drives the welding tungsten needle 48 to rotate around the annular welding rod 84, the external shielding gas delivery equipment continuously sprays shielding gas along the jet pipe 52 and the telescopic pipe 53, and through the jet hole structure 6101 of the arc-shaped baffle 61, towards the welding work area of ​​the welding tungsten needle 48. At the same time, the external suction machine uses the suction pipe 51 to suction the various suction hole structures 4201 on the C-shaped frame 42, so as to promptly remove excess shielding gas and high-temperature fumes generated during welding through the suction hole structures 4201. Plate 61 shields the back side of the welding tungsten needle 48, preventing the suction hole structure 4201 on the back side of the welding tungsten needle 48 from participating in the high-temperature flue gas suction work, and preventing the high-temperature flue gas from being sucked in the direction of the welding tungsten needle 48. During the sliding of the C-shaped slide plate 43 along the C-shaped frame 42, the C-shaped slide plate 43 drives the C-shaped baffle 62 to slide out of the C-shaped frame 42. When the welding tungsten needle 48 is facing the gap of the C-shaped frame 42, the C-shaped baffle 62 is exactly blocking the gap of the C-shaped frame 42, preventing the ejected protective gas from carrying the high-temperature flue gas generated by welding from escaping outward from the gap of the C-shaped frame 42.

[0023] Example 2, based on Example 1 above, as follows: Figures 1-7 As shown, the welding gun body 41 of this embodiment is provided with four fixed insert rods 411, and the welding gun body 41 is detachably connected to the longitudinal electric slider 3 through the fixed insert rods 411. Since the end of the straight pipe 82 is close to the top of the heat sink 81, when there is a local area structure on the heat sink 81 that blocks the annular welding rod 84 between the straight pipe 82 and the U-shaped pipe 83, it is impossible to automatically weld the annular welding rod 84 according to the above steps. At this time, the operator needs to pick up the welding gun body 41 and the fixed insert rods 411 from the longitudinal electric slider 3, hold the welding gun body 41 to adjust the angle of the C-shaped frame 42, manually control the C-shaped frame 42 to surround the blocked annular welding rod 84, and then follow the above steps to make the C-shaped slide plate 43 drive the welding tungsten needle 48 to manually weld the blocked annular welding rod 84. The C-shaped frame 42 is slidably connected to the welding gun body 41; an adjustment screw 412 is rotatably connected to the welding gun body 41; the C-shaped frame 42 is screwed onto the threaded structure of the adjustment screw 412; a knob 413 is fixedly connected to the adjustment screw 412; before the worker holds the welding gun body 41 and controls the C-shaped frame 42 to drive the welding tungsten needle 48 to manually weld the obscured annular welding rod 84, the worker first manually rotates the knob 413 to drive the adjustment screw 412 to rotate. The adjustment screw 412 drives the C-shaped frame 42 to move downward along the welding gun body 41, allowing the C-shaped frame 42 to drive the welding tungsten needle 48 downward. This allows the high-temperature radiant heat generated during subsequent manual welding work to be further away from the worker's hand holding the welding gun body 41, providing protection against burns during manual welding.

[0024] Example 3, based on Example 1 above, as follows: Figures 1-7 As shown, in this embodiment, the fixing block 47 is detachably fixed to the C-shaped slide plate 43 via a threaded structure. The diameters of the annular welding rods 84 used for straight pipes 82 and U-shaped pipes 83 of different sizes are different. To allow the welding tungsten needles 48 to use annular welding rods 84 of different diameters, after removing the fixing block 47 from the C-shaped slide plate 43, the fixing block 47 with welding tungsten needles 48 of different lengths is installed onto the C-shaped slide plate 43. For example, when the diameter of the annular welding rod 84 used on the heat sink 81 in this embodiment is much smaller than the diameter of the annular welding rod 84 used on a conventional heat sink 81, the fixing block 47 used in this embodiment needs to have a longer welding tungsten needle 48 so that the welding tungsten needle 48 can remain close to the used annular welding rod 84. A C-shaped top is detachably inserted into the C-shaped slide plate 43. The cover 49, the C-shaped top cover 49 is designed as an upwardly contracting bucket-shaped structure; when the diameter of the straight pipe 82 and U-shaped pipe 83 used on the heat dissipation box 81 in this embodiment is much smaller than the diameter of the straight pipe 82 and U-shaped pipe 83 used on the conventional heat dissipation box 81, there is a large gap between the C-shaped sliding plate 43 and the straight pipe 82, U-shaped pipe 83 and annular welding rod 84 during the welding of the annular welding rod 84 between the straight pipe 82 and U-shaped pipe 83. Therefore, in this embodiment, a C-shaped top cover 49 is inserted on the C-shaped sliding plate 43. The C-shaped top cover 49 covers the annular welding rod 84 and partially surrounds the outside of the U-shaped pipe 83. It can cooperate with the C-shaped sliding plate 43 to provide more comprehensive protection for the welding of the annular welding rod 84, and reduce the exposure of the high temperature fumes and glaring arc light generated by welding to the air.

[0025] Those skilled in the art should understand that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by equivalent substitution or equivalent transformation fall within the protection scope of the present invention.
