Description

Technical Field

[0004] , , ,

[0001] The present invention relates to the technical field of welding technology, and particularly to an infrared welding machine for welding both-side end plates and extrusion pipes.

Background Art

[0002] With the rapid development of new energy technologies, hydrogen energy, as a clean and highly efficient energy form, has been increasingly widely applied in the energy field. As an important device for hydrogen energy utilization, the manufacturing quality and efficiency of hydrogen storage tanks have a significant impact on the overall performance of the hydrogen energy system. The inner tank, as the core component of the hydrogen storage tank, its quality and performance have a significant impact on the overall operating effect of the device. The welding of both-side end plates and extrusion pipes is an important part of the inner tank manufacturing process, and the welding quality directly affects the strength and sealing performance of the inner tank.

[0003] In the conventional welding method, in the heating process, the phenomenon of uneven heating is likely to occur, resulting in insufficient strength of the welded joint, and even problems such as cracks in the weld bead may occur. Also, due to the differences in the materials and shapes of the end plates and extrusion pipes, deformation is likely to occur during the welding process, affecting the sealing performance and the stability of the overall structure of the hydrogen storage tank. Moreover, during welding, deviation occurs in the positions of the end plates and extrusion pipes, so the welding effect is often not good.

[0004] The patent under publication number CN118664203A discloses a welding apparatus and welding process for a hydrogen storage tank, the apparatus being equipped with a clamping means and a detection means, which, during welding, clamps the lower end of the tank through a chuck and the upper end of the tank through a clamping means, a drive means provided inside the drive seat which rotates the chuck and the upper and lower ends of the tank, thereby welding the area to be welded by the first welding head in all directions. During the welding process of the tank, the detection means is sent into the tank through a sliding frame, and when the detection means and the weld bead are aligned, the welding quality of the weld bead of the tank is detected through the detection means, and if an incompletely welded weld bead is found, the weld bead is secondary welded by the second welding head.

[0005] However, this device still has several problems. While the detection means can perform secondary welding on weld beads that are not completely welded, it cannot guarantee the alignment of the weld area during welding, resulting in deviations after welding is complete, leading to low welding quality for hydrogen storage tanks and the possibility of unexpected problems occurring during use.

Modes for Carrying Out the Invention

[0020] To make the above objects, features, and advantages of the present invention clearer and easier to understand, the specific embodiments of the present invention will be described in detail below in connection with the drawings.

[0021] The following description provides many specific details to fully understand the present invention, but the present invention can also be carried out in other ways not described herein, and those skilled in the art can make similar popularizations without departing from the scope of the present invention; therefore, the present invention is not limited to the specific embodiments disclosed below.

[0022] Furthermore, the terms "one embodiment" or "embodiment" as used herein refer to specific features, structures, or properties that may be included in at least one embodiment of the present invention. The phrases "in one embodiment" found elsewhere in this specification do not all refer to the same embodiment, nor do they refer to an embodiment that is exclusively or selectively exclusive to other embodiments.

[0023] <Example 1> This is a first embodiment of the present invention, which provides an infrared welding machine for welding end plates and an extruded tube.

[0024] Before infrared welding, it is necessary to clean and pre-treat the extruded pipe and end plates to improve welding quality, ensuring that the welding surface is free from oil stains, impurities, etc. Furthermore, the parameters of the infrared welding machine, such as heating power, heating time, and welding pressure, must be adjusted based on the characteristics of the welding material and the welding requirements.

[0025] Before welding, the extruded tube and end plate are adjusted and aligned through the positioning fixing component 200 to ensure close contact. Then, the infrared welding machine 100 emits infrared rays to heat the contact area between the extruded tube and end plate. The infrared rays have high energy and can rapidly raise the temperature of the welding area to the melting point of the material.

[0026] During heating, the temperature of the welding area gradually rises, the material begins to soften, and gradually reaches a molten state. In this process, it is necessary to precisely control the infrared radiation emitted from the infrared welding machine 100 to avoid thermal decomposition or deformation of the material due to excessive heating.

[0027] Once the weld area is molten, a certain amount of pressure is applied to ensure a tight seal between the extruded pipe and the end plate. At this time, the molten material flows under the pressure, filling the weld gap and forming a strong welded joint.

[0028] The magnitude of the welding pressure is extremely important for weld quality. High welding pressure can compensate for any damage that may occur to the material during the heating process, injecting the damaged material into the weld bead, thereby ensuring the strength of the weld.

[0029] After welding is complete, the welded area must gradually cool and harden to allow the welded joint to reach sufficient strength. During the cooling process, it is necessary to avoid defects such as stress concentration and cracking in the welded area due to excessive cooling.

[0030] The cooling rate can be controlled by natural cooling or by using an appropriate cooling device, and at the same time, the internal chamber can be inspected after welding to ensure that the weld quality meets the requirements.

[0031] <Example 2> This is a second embodiment of the present invention, which is implemented based on the previous embodiment.

[0032] Specifically, referring to Figures 1 and 2, the infrared welding machine 100 and The infrared welding machine 100 includes a positioning and fixing component 200 provided inside, the positioning and fixing component 200 includes a positioning ring 205 and a fixing ring 207, an auxiliary ring 206 is provided on the outer wall of the positioning ring 205, a push component 204 is provided on the inner wall of the positioning ring 205, the push component 204 is used to adjust the end plate on the outer wall of the positioning ring 205 so that it is aligned with the outer wall of the extrusion tube, the fixing ring 207 is fitted onto the outer wall of the extrusion tube, a fixing block 208 is provided on the inner wall of the fixing ring 207, the fixing block 208 is used to fix the extrusion tube and to make the end plate tightly attached to the outer wall of the extrusion tube. When the axis of the end plate is misaligned with the axis of the extrusion tube, the push component 204 adjusts the position relative to the end plate, and when the fixing block 208 moves on the inner wall of the fixing ring 207, it fixes the extrusion tube, fixing the end plate while avoiding oscillation, and further adjusting the edge of the end plate to align it with the edge of the extrusion tube.

[0033] In summary, during use, the auxiliary ring 206 and the positioning ring 205 are brought into close contact as a single unit. Then, the end plate is placed on the surfaces of the positioning ring 205 and the auxiliary ring 206. At this time, the movement of the push component 204 causes the end plate to be initially positioned on the outer wall of the positioning ring 205, thereby preventing the end plate from tilting too much and affecting its alignment with the edge of the extruded tube. Subsequently, the fixing ring 207 brings the extruded tube and the end plate closer together. Then, the fixing block 208 on the inner wall of the fixing ring 207 moves toward the axis of the fixing ring 207, fixing the intermediate extruded tube and performing a second position adjustment with respect to the extruded tube and the end plate, thereby preventing the edge from deviating and affecting subsequent welding work.

[0034] <Example 3> This is a third embodiment of the present invention, which is implemented based on the previous embodiment.

[0035] Specifically, referring to Figures 3 to 5, a first moving part 201 is provided at the end of the positioning ring 205 for adjusting the position where the positioning ring 205 is located at the end of the infrared welding machine 100, a first positioning module 2051 is fixed to the outer wall of the positioning ring 205, a first operating chamber 2052 is opened in the inner wall of the positioning ring 205, and a half-gear 2053 is movably provided inside the first operating chamber 2052, and a coil spring 2054 is connected to the end of the half-gear 2053 for resetting the gear 2053 inside the first operating chamber 2052.

[0036] The first moving part 201 moves inside the guide rail on the surface of the infrared welding machine 100, moving the upper positioning ring 205 and adjusting its position on the surface of the infrared welding machine 100.

[0037] The first positioning module 2051 is fixed to the surface of the positioning ring 205. The inner surface of the first positioning module 2051 has an arc shape, making it more closely fitted to the surface of the end plate and convenient for adjusting the end plate on the surface of the first positioning module 2051. As shown in Figure 5, the first working chamber 2052 penetrates the entire interior of the positioning ring 205. The positioning ring 205 is a semicircular ring with a half-gear 2053 inside. The half-gear 2053 moves along the first working chamber 2052. A coil spring 2054 is provided at the bottom end of the first working chamber 2052, and one end of the coil spring 2054 is fixed to the end of the half-gear 2053. When the half-gear 2053 operates inside the first working chamber 2052, it pulls and deforms the coil spring 2054, which is used to reset the half-gear 2053 inside the first working chamber 2052.

[0038] Preferably, the auxiliary ring 206 is provided on the outer wall of the positioning ring 205, a second operating chamber 2061 is opened in the inner wall of the auxiliary ring 206, and the second operating chamber 2061 is in communication with the first operating chamber 2052 and is used for the operation of the half-gear 2053.

[0039] The auxiliary ring 206 is also semicircular and the same size as the positioning ring 205. When they are in close contact, the second operating chamber 2061 inside the auxiliary ring 206 communicates with the first operating chamber 2052 inside the positioning ring 205, and the half-gear 2053 can move from the first operating chamber 2052 into the second operating chamber 2061.

[0040] An opening 2062 is provided at the end face of the auxiliary ring 206, a second positioning module 2063 is movably provided on the inner wall of the opening 2062, a first elastic member 2064 is provided at the end of the second positioning module 2063, and the first elastic member 2064 is used to reset the second positioning module 2063 inside the opening 2062.

[0041] A second positioning module 2063 is provided inside the auxiliary ring 206. Unlike the first positioning module 2051, the second positioning module 2063 expands and contracts inside the auxiliary ring 206 and passes through the second operating chamber 2061. When the half-gear 2053 moves and enters the second operating chamber 2061 and passes through the second positioning module 2063, the half-gear 2053 contacts the inclined surface of the second positioning module 2063, pushing the second positioning module 2063 outward through the opening 2062 of the auxiliary ring 206. This works in cooperation with the first positioning module 2051, which is fixed to the outer wall of the positioning ring 205, to adjust the position of the end plate. The outer surface of the end plate has a constant arc, and the inner surfaces of the three positioning modules are in close contact with the outer surface of the end plate, thereby calibrating the end plate and avoiding excessive tilting.

[0042] Preferably, referring to Figures 3 to 5, the push component 204 is located outside the half-gear 2053, the outer wall of the push component 204 is provided with a boss 2041, and the end of the push component 204 is provided with push teeth 2042, the boss 2041 is used to stop the half-gear 2053, and the push teeth 2042 are used to push the half-gear 2053 so that it rotates on the inner wall of the first operating chamber 2052, the end of the first moving component 201 is further provided with a servo motor 203, the axis of the servo motor 203 is provided with a transmission shaft 2031, and a cam 2032 is fitted onto the outer wall of the transmission shaft 2031, the outer wall of the cam 2032 is in contact with a roller at the end of the push component 204, and the cam 2032 is used to move the push component 204 and push the half-gear 2053 so that it rotates.

[0043] The boss 2041 on the surface of the push part 204 engages with the tooth gap of the half gear 2053, pushing the half gear 2053. Additionally, the top push tooth 2042 is used to push the half gear 2053 in a rotational manner. Each time the cam 2032 rotates once, the roller below the push part 204 enters a recess in the cam 2032, thereby tilting the push part 204 backward, and each time, the top push tooth 2042 falls into the next tooth gap of the half gear 2053. When the projection of the cam 2032 contacts the roller, it pushes the half gear 2053, bringing the push part 204 closer to the half gear 2053 and causing it to rotate.

[0044] To summarize, during use, the first moving part 201 adjusts the position of the positioning rings 205 on both sides. At this time, the auxiliary ring 206 is dropped and brought into close contact with the positioning rings 205, and the end plate is placed outside the positioning rings 205 and auxiliary ring 206. Then, the servo motor 203 rotates the cam 2032 on the transmission shaft 2031. Each time the cam 2032 rotates once, the push part 204 above it moves once, rotating the half-gear 2053 upward within the first operating chamber 2052 and gradually moving it into the second operating chamber 2061 inside the auxiliary ring 206.

[0045] Inside the second operating chamber 2061, two second positioning modules 2063 are uniformly arranged. As the half-gear 2053 rotates inside the second operating chamber 2061, it gradually encounters the second positioning modules 2063. The motion of the half-gear 2053 pushes the second positioning modules 2063 out of the second operating chamber 2061, engaging with the first positioning module 2051, which is fixed to the outer wall of the positioning ring 205.

[0046] The inner surfaces of both the second positioning module 2063 and the first positioning module 2051 are curved and in close contact with the arcuate outer wall of the end plate. The cooperation of the second positioning module 2063 and the first positioning module 2051 maintains the end plate in a calibrated state, thereby preventing it from tilting and affecting its ability to make contact with the outer wall of the extruded tube in the next step.

[0047] <Example 4> This is a fourth embodiment of the present invention, which is implemented based on the previous embodiment.

[0048] Specifically, referring to Figures 2, 6 to 8, a second moving part 202 for adjusting the position of the fixing ring 207 is provided at the end of the fixing ring 207, a chute 2071 is opened in the outer wall of the fixing ring 207, the outer wall of the fixing block 208 slides along the inner wall of the chute 2071, a rotating disc 2072 is movably provided on the inner wall of the fixing ring 207, a spiral ring 2073 is provided on the end face of the rotating disc 2072 and an output gear 2074 is provided on the other end.

[0049] The fixing ring 207 adjusts the position of the surface of the infrared welding machine 100 by the second moving part 202, is placed over the outer wall of the extrusion tube, and moves along the surface of the infrared welding machine 100 together with the extrusion tube.

[0050] A chute 2071 is provided on the surface of the fixing ring 207 for the fixing block 208 to move along the surface of the fixing ring 207. A housing chamber is provided in the inner wall of the fixing ring 207, and a turntable 2072 is mounted inside it. A spiral ring 2073 is provided on the surface of the turntable 2072 to cooperate with the fixing block 208 to move the fixing block 208 inside the chute 2071 on the surface of the fixing ring 207. An output gear 2074 on the other side of the turntable 2072 is used to rotate the turntable 2072 itself.

[0051] Preferably, referring to Figure 8, a recess 2081 is provided in the end face of the fixed block 208 and the recess 2081 is in close contact with the spiral ring 2073, a first fixed rod 2082 is hinged to the end of the fixed block 208, a second fixed rod 2083 is provided on the outer wall of the hinge connection point of the first fixed rod 2082, and a third elastic member 2084 is further provided at the end of the first fixed rod 2082 to push and extend the first fixed rod 2082 outward.

[0052] The fixed block 208 slides along the inner wall of the fixed ring 207, and the recess 2081 on its surface is in close contact with the spiral ring 2073 on the surface of the rotating disk 2072. As the rotating disk 2072 rotates, the spiral ring 2073 moves within the recess 2081 on the underside of the fixed block 208 and causes the fixed block 208 to slide along the outer wall of the fixed ring 207.

[0053] The first fixing rod 2082 and the second fixing rod 2083 are integral, and their intermediate inflection points are hinged to the inner wall of the fixing block 208. As shown in Figure 8, a third elastic member 2084 is further provided at the top of the first fixing rod 2082 to push the tip of the first fixing rod 2082 outward, that is, to make it tightly adhere to the outer wall of the intermediate extrusion tube of the fixing ring 207.

[0054] Preferably, referring to Figures 3, 7, and 8, a first joint 2033 is further fitted onto the outer wall of the transmission shaft 2031, and a second elastic member 2034 is provided in an array on the inner wall of the transmission shaft 2031, with a ball 2035 provided at the end of the second elastic member 2034. The second elastic member 2034 is used to push the ball 2035 and make it adhere tightly to the groove in the inner wall of the first joint 2033, thereby transmitting power to the first joint 2033 together with the transmission shaft 2031. A second joint 2075 is further provided on the inner wall of the fixed ring 207. When the second moving part 202 moves the fixed ring 207, the second joint 2075 engages with the first joint 2033 and rotates together with the first joint 2033. A transmission gear 2076 is provided at the end of the second joint 2075, and the transmission gear 2076 meshes with the output gear 2074. An array of auxiliary gears 2077 is further provided on the inner wall of the fixed ring 207 to assist the transmission gear 2076 in rotating the turntable 2072 on the inner wall of the fixed ring 207.

[0055] A first joint 2033 is further provided at the tip of the transmission shaft 2031, and a groove is made in the inner wall of the first joint 2033, which engages with a second elastic member 2034 and a ball 2035 on the inner wall of the top of the transmission shaft 2031. The second elastic member 2034 pushes the ball 2035 into the groove in the inner wall of the first joint 2033, and this engagement allows the first joint 2033 to rotate together with the transmission shaft 2031. In addition, a second joint 2075 located outside the fixing ring 207 engages with the first joint 2033 in accordance with the movement of the second moving part and rotates together with the first joint 2033.

[0056] When the second coupling 2075 rotates, the transmission gear 2076 on the other side meshes with the output gear 2074 on the underside of the turntable 2072, causing the turntable 2072 to rotate inside the fixing ring 207.

[0057] In summary, during use, the extruder tube is positioned inside the fixing ring 207 and moves toward the positioning ring 205 in conjunction with the second moving part 202. After the second joint 2075 on the surface of the fixing ring 207 engages with the first joint 2033, the end plate is placed outside the positioning ring 205 and the auxiliary ring 206, the auxiliary ring 206 is closed, and the outside of the end plate is brought closer to the inner rings of the positioning ring 205 and the auxiliary ring 206 to perform a simple position fixing. At this time, the edge of the outer wall of the extruder tube approaches the edge of the end plate but does not make contact. Subsequently, the servo motor 203 moves the push part 204, moving the half-gear 2053 inside the positioning ring 205 toward the inside of the auxiliary ring 206. At this time, the second joint 2075 rotates the turntable 2072, and the fixing block 208 located on the surface of the fixing ring 207 begins to move toward the center of the fixing ring 207 and approaches the extruder tube.

[0058] The three fixed blocks 208 move synchronously to the extrusion tube, fixing it in place. Because the fixed blocks 208 and the half-gear 2053 move at different speeds, when the fixed blocks 208 clamp the intermediate extrusion tube, the half-gear 2053 moves into the second operating chamber 2061 inside the first operating chamber 2052. At this time, the transmission shaft 2031 continues to move, and the first coupling 2033 located at the end of the transmission shaft 2031 engages with the second coupling 2075. At this time, the second coupling 2075 cannot continue to move, and neither can the first coupling 2033. Restricted by the second joint 2075, the ball 2035 inside the transmission shaft 2031 moves inward due to the influence of the groove in the inner wall of the first joint 2033 and presses against the second elastic member 2034, at which point the transmission shaft 2031 detaches from the first joint 2033 and can continue to move the half-gear 2053 through the push component 204, and the fixing block 208 does not retract due to the influence of the spiral ring 2073 and fixes the extrusion pipe.

[0059] When the fixed block 208 is in close contact with the extrusion tube, the first fixed rod 2082 at one end contracts against the inner wall of the fixed block 208 due to the action of the outer wall of the extrusion tube. At this time, the second fixed rod 2083 at the other end rotates around the connection point as its axis and moves downward. The tip of the second fixed rod 2083 is brought into close contact with the outer wall of the end plate and moves the end plate in the direction of the extrusion tube. Meanwhile, the half-gear 2053 continues to move into the second operating chamber 2061 within the first operating chamber 2052, gradually pushing the two second positioning modules 2063 outward and bringing them into close contact with the outer wall of the end plate. At this time, the end plate is brought into close contact with the outside of the extrusion tube. Due to the action of the three positioning modules, the axes of the end plate and the extrusion tube are on the same horizontal line, contributing to the close contact of the welded edges of the end plate and the extrusion tube.

[0060] Once welding is complete, the servo motor 203 reverses, moving the fixed block 208 to loosen the extrusion pipe, and a lifting platform is provided between the first moving part 201 and the servo motor 203, allowing the servo motor 203 to descend. After the first joint 2033 and the second joint 2075 separate, the servo motor 203 can descend on the first moving part 201, at which point the cam 2032 falls together with the roller of the push part 204, the push part 204 reverses and does not mesh with the half gear 2053, and then the coil spring 2054 pulls the half gear 2053 back to its original position.
