Description

Technical Field

[0001] The invention belongs to the technical field of welding, and in particular relates to an oil cup welding device and an oil cup welding method. Background Art

[0002] Existing range hoods are generally equipped with oil cups, whose main function is to collect grease discharged from the inside of the range hood or the ventilation duct. These oil cups are mostly made of stainless steel and made by welding. The quality of welding has a crucial impact on the overall performance of the oil cup. During the welding process, traditional oil cups are prone to oxidation at the weld due to the high temperature, leaving yellow or black marks on the weld. In order to solve this problem, it is usually necessary to perform additional manual processing on the weld after welding, such as grinding, polishing and wire drawing, to ensure that the surface of the oil cup is smooth and flat. However, such a processing process will not only reduce the production efficiency of the oil cup, but also increase the manufacturing cost.

[0003] To address this problem, the prior art adds vent holes corresponding to the welding points on the basis of traditional welding equipment to allow protective gas to flow directly to the welding points to prevent oxidation of the weld. Although this design can reduce the discoloration of the oil cup weld to a certain extent, the direct effect of the protective gas on the welding point will cause a cold weld. In addition, the overall structure of this type of welding equipment is often complex, which increases the manufacturing cost. Summary of the invention

[0030] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0031] like Figures 1 to 6 As shown, an oil cup welding device comprises:

[0032] A welding tool, the welding tool comprises a bracket 100, the bracket 100 is provided with a positioning mechanism and a fixing mechanism, the positioning mechanism comprises a positioning seat 200 adapted to the shape of the oil cup, a gap is provided between the positioning seat 200 and the welding point of the oil cup, and a plurality of air outlet channels 210 are provided on the side of the positioning seat 200 close to the welding point, each air outlet channel 210 is respectively connected to the gap and forms a height difference with the welding point, and the fixing mechanism and the positioning seat 200 cooperate to position and fix the end of the oil cup;

[0033] A laser welding machine 500, which is arranged on the adjacent side of the welding tool and is used to weld the oil cup;

[0034] The cooling assembly 600 includes a nitrogen tank 610 and a controller 620. The nitrogen tank 610 is connected to the controller 620, and a gas supply channel connected to the gas outlet channel 210 is formed through the controller 620. The controller 620 is electrically connected to the laser welding machine 500, and can connect or disconnect the gas supply channel according to the signal of the laser welding machine 500. When the nitrogen in the nitrogen tank 610 is filled into the gas outlet channel 210, the nitrogen first flows along the gas outlet channel 210 to the side wall of the oil cup, and then flows from the side wall to the welding point. This design enables the equipment to automatically and quickly cool the oil cup in welding, which not only avoids the yellowing or blackening of the oil cup during the welding process, saves subsequent processes, but also improves the automation of the equipment, thereby effectively improving the production efficiency of the oil cup and reducing the labor manufacturing cost; in addition, the height difference design also avoids the direct impact of nitrogen on the weld to cause a cold weld, effectively ensuring the welding effect of the oil cup.

[0035] Specifically, if Figures 1 to 6 As shown, in this embodiment, the oil cup welding equipment includes a cooling assembly 600, a welding tool and a laser welding machine 500 arranged from left to right, wherein the cooling assembly 600 is used to cooperate with the laser welding machine 500 to cool the oil cup during the welding process, and the welding tool is used to position and fix the oil cup so that the laser welding machine 500 can weld the oil cup. Through the cooperation of the cooling assembly 600, the welding tool and the laser welding machine 500, the automatic welding of the oil cup is realized, the production efficiency of the oil cup is effectively improved, and the intervention of the cooling assembly 600 is used to ensure the welding effect of the oil cup.

[0036] In this embodiment, the cooling assembly 600 is detachably connected to the bracket 100, and includes a nitrogen tank 610 and a controller 620. The nitrogen tank 610 is used to deliver a stable cooling medium, and the controller 620 is used to cooperate with the laser welding machine 500 to control the opening and closing of the cooling medium delivery. Among them, the nitrogen tank 610 is detachably connected to the controller 620 through an air pipe, and the controller 620 is detachably connected to the bracket 100 through an air pipe, and cooperates with the nitrogen tank 610 to form an air supply channel connected to the air outlet channel 210, and the controller 620 is also electrically connected to the laser welding machine 500, and can connect or disconnect the air supply channel according to the signal of the laser welding machine 500. This design not only ensures that the cooling medium can be smoothly delivered to the air outlet channel 210, but also realizes the intelligent opening and closing when the cooling medium is delivered, which not only ensures the accuracy of the cooling medium delivery timing, but also avoids the waste of cooling medium. In addition, the detachable design also improves the convenience of disassembly and maintenance of the cooling assembly 600.

[0037] In this embodiment, the gas supply channel includes a first channel, a second channel and a third channel 630 that are interconnected. The first channel is provided between the nitrogen tank 610 and the controller 620, specifically located on the air pipe between the nitrogen tank 610 and the controller 620. The second channel is provided between the controller 620 and the bracket 100, specifically located on the air pipe between the controller 620 and the bracket 100. The third channel 630 is provided between the second channel and the gas outlet channel 210, specifically located on the longitudinal plate 102 of the bracket 100; wherein, there is a height difference between the inlet of the third channel 630 and the gas supply channel. The hierarchical arrangement of the gas supply channel ensures that the controller 620 can control the connection and disconnection of the gas supply channel according to the signal of the laser welding machine 500, thereby realizing intelligent and precise gas supply. The height difference design of the third channel 630 enables the nitrogen to flow along a natural path in the gas supply channel, reducing eddy currents and turbulence caused by unreasonable pipeline layout, thereby reducing resistance during gas transmission; and, compared with the horizontal transportation method, it can also reduce the formation of local high-pressure areas, effectively improving the stability and reliability of the nitrogen transportation process.

[0038] In this embodiment, the third channel 630 is arc-shaped, one end of which is connected to each outlet channel 210, and the other end extends toward the second channel and penetrates the longitudinal plate 102 to be connected to the second channel. This design further reduces the resistance during nitrogen transmission and ensures that the gas can reach the outlet channel 210 quickly and stably.

[0039] In this embodiment, the bracket 100 is arranged in an inverted T shape, including a horizontal plate 101 and a vertical plate 102 connected vertically to each other, the horizontal plate 101 is arranged horizontally, the vertical plate 102 is vertically arranged on the horizontal plate 101, and the positioning mechanism, the fixing mechanism and the third channel 630 are all arranged on the vertical plate 102. The coordinated design of the horizontal plate 101 and the vertical plate 102 saves materials while effectively ensuring the stability of the bracket 100 when placed, and meets the height requirement during oil cup processing.

[0040] Preferably, in this embodiment, a sealing joint 110 is provided on the side of the longitudinal plate 102 facing the controller 620 and opposite to the entrance of the third channel 630. One end of the sealing joint 110 is connected to the third channel 630, and the other end is connected to the second channel to ensure the airtightness of the connection between the two.

[0041] In this embodiment, the positioning mechanism includes a positioning seat 200 fixed on the longitudinal plate 102 and adapted to the shape of the oil cup. When the oil cup is placed on the positioning seat 200, there is a gap between the positioning seat 200 and the welding part of the oil cup to ensure that the nitrogen has a flow space to cool the welding point. Among them, the positioning seat 200 includes a first positioning surface 201, a second positioning surface 202 and a third positioning surface 203 connected in sequence, and a fourth positioning surface 204 arranged above the first positioning surface 201, the second positioning surface 202 and the third positioning surface 203 and vertically connected thereto. The design of the positioning seat 200 forms a support for the oil cup, preventing the oil cup from deforming during the welding process.

[0042] In this embodiment, the positioning mechanism also includes a plurality of gas outlet channels 210 disposed on one side of the positioning seat 200 close to the welding point. The gas outlet channels 210 extend from the inside to the outside and are tilted toward the bottom of the welding point to form a height difference with the welding point. After the tilt, the angle between the axis of the gas outlet channel 210 and the horizontal line is 5° to 6°. This design allows the nitrogen flowing out of the gas outlet channel 210 to first flow to the side wall of the oil cup, and then flow from bottom to top to the welding point to cool the weld. While ensuring that the weld is cooled in time, it avoids nitrogen directly impacting the weld to cause a cold weld, effectively improving the welding effect of the oil cup.

[0043] Preferably, in this embodiment, one end of a plurality of gas outlet channels 210 is respectively connected to the third channel 630, and the outlet end of the third channel 630 is used as the center point, and the gas outlet channels 210 are distributed in a fan shape, and there is an angle between two adjacent gas outlet channels 210, and the angle is greater than 5° and less than 90°. This design improves the uniformity and comprehensiveness of the cooling gas distribution, and effectively ensures the continuous cooling of the oil cup welding process.

[0044] It is worth noting that, in the present embodiment, two groups of the positioning mechanisms are provided, and the positioning seats 200 of the two groups of positioning mechanisms are arranged in a mirror image, so as to respectively weld the two ends of the oil cup in different directions, thereby effectively ensuring the flexibility of the oil cup welding.

[0045] In this embodiment, the fixing structure includes a first fixing assembly 300 and a second fixing assembly 400 detachably arranged on the longitudinal plate 102, wherein the first fixing assembly 300 is provided with two groups, which are respectively located on the left and right sides of the positioning seat 200, and the second fixing assembly 400 is located above the positioning seat 200, and the first fixing assembly 300 cooperates with the fixing seat to limit the movement of the oil cup in the X-axis and Y-axis directions, and the second fixing structure cooperates with the positioning seat 200 to limit the movement of the oil cup in the Z-axis direction. This design effectively ensures the stability of the oil cup in all directions during the welding process, thereby ensuring the welding quality of the oil cup, and through the detachable design, improves the convenience of disassembly and maintenance of the fixing mechanism.

[0046] In this embodiment, the two groups of first fixing components 300 have the same structure and are arranged symmetrically. Each group of first fixing components 300 includes a first fixing seat 310, a first linkage structure 320 and a first clamping member 330. The first fixing seat 310 is detachably connected to the longitudinal plate 102. The first linkage structure 320 is rotatably connected to the first fixing seat 310 and is detachably connected to the first clamping member 330. The first linkage structure 320 has a first rotation position and a second rotation position. When the first linkage structure 320 is in the first rotation position, the first clamping member 330 abuts against the outer wall of the oil cup. When the first linkage structure 320 is in the second rotation position, the first clamping member 330 is separated from the outer wall of the oil cup. This design enables the operator to fix and release the oil cup in the X-axis and Y-axis directions by rotating the first linkage structure 320, ensuring the flexibility and convenience of the operator in fixing the oil cup, effectively improving the efficiency of fixing and disassembling the oil cup, and improving the overall efficiency of oil cup welding.

[0047] Preferably, in this embodiment, the first clamping member 330 has a first abutting portion 331 and a second abutting portion 332 connected to each other. When the first linkage structure 320 is in the first rotation position, the first abutting portion 331 and the second abutting portion 332 respectively abut against the outer wall of the oil cup corresponding to the first positioning surface 201 and the second positioning surface 202, or the outer wall of the oil cup corresponding to the second positioning surface 202 and the third positioning surface 203; when the first linkage structure 320 is in the second rotation position, the first abutting portion 331 and the second abutting portion 332 are separated from the corresponding outer wall of the oil cup. This design effectively expands the contact area between the first clamping member 330 and the outer wall of the oil cup when fixed, and further ensures the stability of the oil cup fixation.

[0048] In this embodiment, the first linkage structure 320 includes a first handle 321 and a first rotating arm 322. The first handle 321 is rotatably connected to the first fixed seat 310 and is connected to the first rotating arm 322 through a first connecting rod 323. One end of the first rotating arm 322 is rotatably connected to the first fixed seat 310, and the other end is detachably connected to the first clamping member 330. When the first handle 321 rotates, it can drive the first rotating arm 322 to rotate and move the first clamping member 330 toward or away from the positioning seat 200. This design allows the operator to move the first clamping member 330 by pulling the first handle 321 horizontally, which greatly improves the convenience of operation.

[0049] It is worth noting that the detachable connection between the first rotating arm 322 and the first clamping member 330 allows the angle between the first rotating arm 322 and the first clamping member 330 to be adjusted as needed, which effectively improves the adaptability and flexibility of the first fixing assembly 300.

[0050] In this embodiment, the second fixing assembly 400 includes a second fixing seat 410, a second linkage structure 420 and a second clamping member 430. The second fixing seat 410 is detachably connected to the longitudinal plate 102. The second linkage structure 420 is rotatably connected to the second fixing seat 410 and is detachably connected to the second clamping member 430. The second linkage structure 420 has a third rotation position and a fourth rotation position. When the second linkage structure 420 is in the third rotation position, the second clamping member 430 abuts against the outer wall of the oil cup. When the second linkage structure 420 is in the fourth rotation position, the second clamping member 430 is separated from the outer wall of the oil cup. This design enables the operator to fix and release the oil cup in the Z-axis direction by rotating the second linkage structure 420, thereby ensuring the flexibility and convenience of the operator in fixing the oil cup, effectively improving the efficiency of fixing and removing the oil cup, and improving the overall efficiency of oil cup welding.

[0051] Preferably, in this embodiment, the second clamping member 430 has a third abutting portion 431 extending along the length direction of the fourth positioning surface 204; when the second linkage structure 420 is in the third rotation position, the third abutting portion 431 abuts against the outer wall of the oil cup corresponding to the fourth positioning surface 204; when the second linkage structure 420 is in the fourth rotation position, the third abutting portion 431 is separated from the corresponding outer wall of the oil cup. This design effectively expands the contact area between the second clamping member 430 and the outer wall of the oil cup when fixed, and further ensures the stability of the oil cup fixation.

[0052] In this embodiment, the second fixed seat 410 has a groove 411, and the second linkage structure 420 includes a second handle 421 and a second rotating arm 422. The second handle 421 is rotatably connected to the second fixed seat 410 through a second connecting rod 423, and is hinged to the second rotating arm 422. One end of the second rotating arm 422 is rotatably connected to the second fixed seat 410, and the other end is detachably connected to the second clamping member 430. When the second handle 421 rotates, it can drive the second rotating arm 422 to rotate, and move the second clamping member 430 toward or away from the positioning seat 200. When the second linkage structure 420 is in the third rotation position, the hinge point of the second handle 421 and the second rotating arm 422 is in the groove 411. This design allows the operator to move the first clamping member 330 by pulling the second handle 421 longitudinally, which greatly improves the convenience of operation.

[0053] The embodiment of the present invention further provides an oil cup welding method, which is implemented based on the above oil cup welding device, wherein the oil cup includes a base and a side piece to be welded, and the welding method includes:

[0054] S1: First, the base is sleeved on the positioning seat 200 and fixed by a fixing mechanism, and then the side piece is placed on the positioning seat 200 so that the side piece fits the base and is fixed by a fixing mechanism to achieve positioning and fixing of the oil cup so that the laser welding machine 500 can perform welding operation;

[0055] S2: Start the laser welding machine 500 and the nitrogen tank 610, so that the laser welding machine 500 automatically moves to the welding position and performs welding. When the laser welding machine 500 is welding, a start signal is synchronously sent to the controller 620, and the controller 620 connects the gas supply channel, so that the nitrogen is quickly filled into the gas outlet channel 210, and flows along the gas outlet channel 210 to the side wall of the oil cup, and then flows from the side wall to the welding point, so as to achieve synchronous cooling during welding; when the laser welding machine 500 completes welding, a closing signal is synchronously sent to the controller 620, and the controller 620 disconnects the gas supply channel, stops supplying gas to the gas outlet channel 210, and completes a single welding operation.

[0056] This welding method realizes the automation of the welding process and the synchronous cooling of the welding points through the coordinated work of the laser welding machine 500 and the controller 620, which improves the welding efficiency and quality while saving subsequent processes, effectively improving production efficiency and reducing production costs.
