Description

Technical Field

[0001] This utility model relates to the field of welding technology, and in particular to a welding alignment mechanism and a welding device for evaporator components. Background Technology

[0002] To improve welding efficiency and reduce labor costs, automated welding equipment is widely used. In existing automated welding equipment, the welding torch is manually ignited after initial adjustment of its position. Then, a robot drives the torch tip to approach the welding start point on the product and moves along the weld seam to complete the welding.

[0003] Because the evaporator components consist of small elbows, connecting pipes, liquid distribution branch pipe assemblies, and gas collection branch pipe assemblies, there are as many as 12-16 welding points distributed in a small space, resulting in a complex layout. This greatly increases the difficulty of welding.

[0004] When existing automatic welding equipment welds evaporator components, the welding torch has difficulty moving within the space, resulting in low accuracy in weld point alignment, which cannot meet the high-precision welding requirements of evaporator components. Utility Model Content

[0043] The following is combined Figures 1-6 The technical solution provided by this utility model will be described in more detail.

[0044] This utility model provides a welding alignment mechanism 100, comprising:

[0045] Alignment boss 110, wherein alignment boss 110 is provided with alignment hole 111;

[0046] The positioning component includes a moving structure 120 and a reset structure 130. The alignment boss 110 is disposed on the moving structure 120 so that the alignment boss 110 can reciprocate along a first direction. The reset structure 130 is used to drive the alignment boss 110 to the initial position.

[0047] The micro-motion triggering component 140 includes a trigger spring 141, which is disposed on the moving path of the alignment boss 110 to detect whether the alignment boss 110 has disengaged from its initial position.

[0048] The welding alignment mechanism 100 provided by this utility model includes an alignment boss 110, a positioning component, and a micro-motion triggering component 140. The positioning component includes a moving structure 120 and a reset structure 130. The alignment boss 110 is disposed on the moving structure 120 so that the alignment boss 110 can reciprocate along a first direction. The reset structure 130 is used to drive the alignment boss 110 to an initial position. The trigger spring 141 of the micro-motion triggering component 140 is disposed on the moving path of the alignment boss 110. The alignment boss 110 is provided with an alignment hole 111. By obtaining the positional relationship between the alignment hole 111 and the welding torch, it is possible to know whether the positional accuracy of the welding torch meets the requirements. Thus, the positional accuracy of the welding torch can be ensured before welding, thereby improving the welding effect and welding quality.

[0049] It is understood that the alignment boss 110 can reciprocate along the first direction. The reset structure 130 is used to drive the alignment boss 110 to the initial position. When the welding torch moves under the drive of the robot 400 to engage with the alignment hole 111, if the welding torch and the alignment hole 111 are precisely engaged, the alignment boss 110 will not move and will remain in the initial position, and the trigger spring 141 will not move. However, when the welding torch moves under the drive of the robot 400 to engage with the alignment hole 111, if the welding torch deviates from the alignment hole 111, the alignment boss 110 will disengage from the initial position under the drive of the welding torch, thereby driving the trigger spring 141 to move. This allows for timely detection that the welding torch position accuracy does not meet the requirements, necessitating adjustment of the welding torch position to meet the accuracy requirements and improve welding quality.

[0050] It should be noted that the micro-motion triggering component 140 includes a trigger spring 141, which is disposed on the moving path of the alignment boss 110. When the alignment boss 110 moves, the alignment boss 110 will drive the trigger spring 141 to move, thereby triggering an alarm or issuing a prompt through the micro-motion triggering component 140, so as to ensure that the subsequent welding process can be completed under the requirement of high precision and avoid the problem of batch welding abnormalities.

[0051] In some embodiments of this utility model, the movable structure 120 includes a sliding guide rail 121 and a first guide shaft 122, the first guide shaft 122 being slidably disposed on the sliding guide rail 121, and the alignment boss 110 being connected to the first guide shaft 122.

[0052] In some embodiments of the present invention described above, the movable structure 120 includes a sliding guide rail 121 and a first guide shaft 122. The first guide shaft 122 cooperates with the sliding guide rail 121 and is slidably disposed on the sliding guide rail 121. The alignment boss 110 is connected to the first guide shaft 122 so that the alignment boss 110 can reciprocate along a first direction. Due to the cooperation between the sliding guide rail 121 and the first guide shaft 122, the alignment boss 110 can reciprocate in the first direction, ensuring that the alignment boss 110 has high movement accuracy, effectively guaranteeing the alignment accuracy of the welding torch, and improving the welding quality.

[0053] In some embodiments of this utility model, the movable structure 120 further includes a first bearing mounting plate 123 and a second bearing mounting plate 124, wherein the first bearing mounting plate 123 and the second bearing mounting plate 124 are arranged in parallel.

[0054] The first bearing mounting plate 123 and the second bearing mounting plate 124 are coaxially provided with sliding bearings 125. The second guide shaft 126 is slidably disposed in the two sliding bearings 125. The first guide shaft 122 and the second guide shaft 126 are arranged in parallel. The two ends of the alignment boss 110 are respectively connected to the first guide shaft 122 and the second guide shaft 126.

[0055] In some embodiments of the present invention described above, the movable structure 120 further includes a first bearing mounting plate 123 and a second bearing mounting plate 124, which are arranged in parallel. A sliding bearing 125 is coaxially arranged on the first bearing mounting plate 123 and the second bearing mounting plate 124. A second guide shaft 126 is slidably disposed within the two sliding bearings 125, thereby enabling the second guide shaft 126 to slide on the first bearing mounting plate 123 and the second bearing mounting plate 124, ensuring that the second guide shaft 126 has high reciprocating movement accuracy. Simultaneously, the second guide shaft 126 and the first guide shaft 122 are arranged in parallel, and both ends of the alignment boss 110 are connected to the second guide shaft 126 and the first guide shaft 122 respectively. With the cooperation of the sliding guide rail 121 and the sliding bearing 125, the alignment boss 110 has higher movement accuracy. When the welding torch deviates from the alignment hole 111, the alignment boss 110 can move along the first direction, thereby driving the trigger spring 141 to move.

[0056] In some embodiments of this utility model, the reset structure 130 includes a reset spring 131, which is sleeved on the second guide shaft 126, and a spring limiter 132 is provided on the second guide shaft 126. The reset spring 131 is disposed between the first bearing mounting plate 123 and the spring limiter 132, and the elastic force of the reset spring 131 is used to drive the alignment boss 110 to the initial position.

[0057] In some embodiments of the present invention described above, the reset structure 130 includes a reset spring 131, which is disposed between the first bearing mounting plate 123 and the spring limiter 132. The elastic force of the reset spring 131 is used to drive the alignment boss 110 to the initial position. When the welding torch misaligns and drives the alignment boss 110 to move, it will overcome the elastic force of the reset spring 131. When the welding torch moves away, the elastic force of the reset spring 131 can allow the alignment boss 110 to return to the initial position, thereby ensuring that the alignment boss 110 has high movement accuracy.

[0058] In some embodiments of this utility model, a limiting groove 128 is provided on the first guide shaft 122, and the trigger spring 141 elastically abuts against the limiting groove 128.

[0059] In some embodiments of the present invention described above, by providing a limiting groove 128 on the first guide shaft 122, the trigger spring 141 elastically abuts against the limiting groove 128. When the alignment protrusion moves, the first guide shaft 122 slides along the sliding guide rail 121, thereby driving the trigger spring 141 to move, thereby enabling the detection of whether the alignment protrusion 110 has disengaged from its initial position.

[0060] It is understood that the trigger spring 141 can also be set on the moving path of the second guide shaft 126.

[0061] In some embodiments of this utility model, the inner diameter of the alignment hole 111 is 1 mm larger than the outer diameter of the welding torch; and / or, an igniter 150 is also provided on the base 127.

[0062] In some of the embodiments of this utility model described above, the inner diameter of the alignment hole 111 is 1 mm larger than the outer diameter of the welding torch, allowing the welding torch to extend into the alignment hole 111. If the welding torch deviates, it may collide with the alignment hole 111, thereby driving the alignment boss 110 to move and triggering an alarm.

[0063] Furthermore, an igniter 150 is provided on the base 127. When the positional accuracy of the welding torch meets the requirements, the welding torch is ignited by the igniter 150, thereby improving the ignition efficiency.

[0064] This utility model also provides a welding device for evaporator components, including the welding alignment mechanism 100 as described above.

[0065] The evaporator component welding device provided by this utility model includes the welding alignment mechanism 100 as described above, which has the beneficial effect of knowing whether the positional accuracy of the welding torch meets the requirements, thereby ensuring the positional accuracy of the welding torch before welding, thus improving the welding effect and welding quality.

[0066] In some embodiments of this utility model, the evaporator component welding device further includes a welding torch mechanism 200, which includes a welding torch body 210 and a nozzle 240. A vertically downward connecting rod 220 is provided on the welding torch body 210, and the nozzle 240 is connected to the connecting rod 220 through an L-shaped welding torch connector 230.

[0067] In some embodiments of the present invention described above, a welding torch mechanism 200 is also included. The welding mechanism includes a welding torch body 210 and a nozzle 240. A connecting rod 220 is provided on the welding torch body 210. The nozzle 240 is connected to the connecting rod 220 through an L-shaped welding torch connector 230, thereby making the nozzle 240 and the connecting rod 220 form a right-angle structure. This reduces the volume in the horizontal space, facilitates the movement of the welding torch under the dense piping of the evaporator components, and allows for quick and rapid switching of welding positions, which is more conducive to the welding of evaporator components.

[0068] In some embodiments of this utility model, a flame detector 250 is also provided on the welding torch body 210, and the flame detector 250 is provided corresponding to the outlet of the nozzle 240.

[0070] In some embodiments of this utility model, a top-view vision camera assembly 260 is also provided on the welding torch body 210.

[0071] In some of the embodiments of the present invention described above, a top-view vision camera assembly 260 is provided on the welding torch body 210.
