Description

Technical Field

[0001] The invention belongs to the technical field of welding equipment, in particular to a welding device for a coffee machine heating element. Background Art

[0002] The coffee machine heating element usually refers to the heater or heating component inside the coffee machine. The heating component is usually composed of a heating tube and a metal sheet. The heating tube not only has a higher heating efficiency, but also has better uniformity, and can better meet the high-frequency use needs of the coffee machine. In the production process of the heating component, since the metal sheet has good thermal conductivity, the heating tube will be welded to the surface of a metal sheet to finally form a heating component, thereby ensuring that the heat is quickly and evenly transferred from the heating tube to the metal sheet, and then transferred to the water in the coffee machine.

[0003] When existing welding equipment is used to weld the heating tube and the metal plate, some welding equipment will produce unobservable sticky slag on the electrodes at the welding part after excessive use, which will lead to poor contact of the electrode surface and the inability to accurately control the temperature during subsequent welding, ultimately making the welding temperature too low or too high. This phenomenon will cause the welding part to fail to melt completely or melt excessively, thereby affecting the strength and stability of the welding point, and further causing the metal sheet to tilt. At this time, the heating tube and the metal circular plate are not perpendicular to each other, which will affect the subsequent use of the electric heating tube. If it cannot be discovered in the first time, most of the products after welding will have poor quality, resulting in cost losses. In addition, the welding of the heating components is generally multiple. If assembly line welding is not performed, the working cycle will be affected.

DETAILED DESCRIPTION

[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0036] Specifically, a coffee machine heating element welding device of the scheme is mainly used for welding the heating element of the coffee machine. The heating element is composed of a heating tube 6 and a metal sheet 7 welded together. The heating tube 6 is "U"-shaped, and the metal sheet 7 is rectangular, and a hole for the heating tube 6 to pass through is opened on the surface. When welding, first put the straight part of the heating tube 6 between the adjustment buckle 312 and the movable buckle 313. Due to the extrusion of the heating tube 6, the adjustment buckle 312 and the movable buckle 313 will move away from the heating tube 6. At this time, the compression spring 314 at one end of the movable buckle 313 is releasing its elastic force, and the return spring 311 between the first sliding plate 309 and the second sliding plate 310 is also releasing its elastic force, so that the heating tube 6 can be clamped in the end, and then The metal sheet 7 is placed under the heating tube 6 and moves upward so that the metal sheet 7 passes through the heating tube 6. At this time, the welding host inside the welding module 4 is started, and the welding host will transmit current to the welding head 41. The welding method of the welding head 41 is arc welding. Then the welding head 41 will move upward and finally contact with the welding part. When it contacts the surface of the metal sheet 7, the welding head 41 will move downward quickly to form an arc discharge. Then, through multiple repeated operations, and gradually adding welding wire to the welding part during the welding process, a cladding layer is formed. The cladding layer will be mixed with the molten metal on the surface of the metal sheet 7 to realize the connection between the metal sheet 7 and the heating tube 6. However, during the welding process, if the heating tube 6 and the metal sheet 7 are not perpendicular to each other, the connection will be reduced. The overall stability of the structure may cause the heating tube 6 to become loose or deformed during long-term use, causing safety hazards. For this reason, an abutment rod 317 is designed. Since the equipment will be transferred through the turntable 2 after welding, continuous welding work can be performed. When the turntable 2 moves the welded heating tube 6 to just above the support plate 316, the support plate 316 is started and the support plate 316 will move upward. When the metal sheet 7 is perpendicular to the heating tube 6, the abutment rods 317 distributed at the four corners of the support plate 316 will eventually abut against the lower surface of the metal sheet 7. At this time, the sliding rack 320 will also move to a position meshing with the lower gear 303. When the turntable 2 continues to rotate, the lower gear 303 will mesh with the sliding rack 320. The lower gear 303 will also drive the upper gear 307 to rotate together. At this time, the upper gear 307 will drive the second rack 308 to move, so that the movable buckle 313 and the adjusting buckle 312 move in the direction away from each other, and finally the heating tube 6 is no longer clamped, so that it falls off for subsequent collection. When the metal sheet 7 and the heating tube 6 are not perpendicular to each other, the abutment rod 317 will contact the downward inclined end of the metal sheet 7 in advance, and finally the sliding rack 320 will not move to a position flush with the lower gear 303, and finally the movable buckle 313 and the adjusting buckle 312 will not be opened, and finally the heating tube 6 will not fall off. This heating tube 6 that cannot fall off automatically is a product with unqualified welding and needs to be discarded.

[0037] like Figures 1 to 8 As shown, the clamping structure 3 also includes: a connecting arm 319, which is arranged at the lower end of the sliding rack 320; a lifting block 318, which is slidably connected to the side wall of the base frame 1, and one end of the lifting block 318 is connected to the connecting arm 319, and the other end of the lifting block 318 is connected to the support plate 316.

[0038] Specifically, when the welded heating tube 6 moves to the top of the support plate 316, the lifting block 318 is started, and the lifting block 318 will move with the connecting arm 319 and the support plate 316, so as to perform a qualified inspection on the welded heating tube 6.

[0039] like Figures 1 to 8 As shown, a connecting frame 301 is provided at the upper end of the clamping frame 302 , and an auxiliary hook 305 is rotatably connected to the inner upper end of the connecting frame 301 .

[0040] Specifically, by setting the auxiliary hook 305, when the straight part of the heating tube 6 is placed between the adjusting buckle 312 and the movable buckle 313, the auxiliary hook 305 is started to rotate, and the auxiliary hook 305 will rotate to hook the curved part of the heating tube 6, so that the upper end of the heating tube 6 can be properly fixed when welding.

[0041] like Figures 1 to 8 As shown, the connecting frame 301 is internally slidably connected with a sliding rod 304, and the end of the sliding rod 304 close to the upper gear 307 is connected to the first rack 306, and the first rack 306 is meshed with the upper gear 307. The sliding rod 304 is provided with a sliding sleeve 322 at one end close to the auxiliary hook 305. The upper end of the interior of the connecting frame 301 is rotatably connected with a rotating shaft 321, and the rotating shaft 321 is connected to the auxiliary hook 305. The sliding sleeve 322 slides on the surface of the rotating shaft 321, and a thread 323 is provided on the surface of the rotating shaft 321.

[0042] Specifically, when the straight part of the heating tube 6 is placed between the adjusting buckle 312 and the movable buckle 313, the adjusting buckle 312 and the movable buckle 313 will move in the direction away from the heating tube 6, and the upper gear 307 will rotate at this time, and then the upper gear 307 will drive the sliding rod 304 to move through the first rack 306, and the sliding sleeve 322 at one end of the sliding rod 304 will slide along the surface of the rotating shaft 321 and finally contact with the thread 323. Since the sliding sleeve 322 and the thread 323 are connected, the rotating shaft 321 can drive the auxiliary hook 305 to rotate, and finally hook the bent part of the heating tube 6, and when the welded metal sheet 7 is perpendicular to the heating tube 6, the upper gear 307 will continue to rotate, and the sliding sleeve 322 will slide until it no longer contacts with the thread 323, and the auxiliary hook 305 will no longer hook the bent part of the heating tube 6, so that the heating tube 6 can fall off automatically.

[0043] like Figures 1 to 5 As shown, an auxiliary inclined plate 315 is provided at one end of the adjusting buckle 312 and the movable buckle 313 away from the connecting frame 301 .

[0044] Specifically, by setting the auxiliary inclined plate 315, when the straight part of the heating tube 6 is placed between the adjusting buckle 312 and the movable buckle 313, the heating tube 6 will first contact the auxiliary inclined plate 315, and finally be guided by the auxiliary inclined plate 315 to enter between the adjusting buckle 312 and the movable buckle 313, thereby not causing damage to the surface of the heating tube 6.

[0045] Embodiment 2

[0046] like Figures 1 to 13 As shown, compared with Example 1, another implementation of the present invention is: a loading structure 5 is provided at one end of the base frame 1 away from the lifting block 318; the loading structure 5 includes: a sliding frame 503, the sliding frame 503 is slidably connected to the upper end of the base frame 1; a paddle 508, the paddle 508 is rotatably connected to the inside of the sliding frame 503, and the paddle 508 is perpendicular to the moving direction of the sliding frame 503 in the initial state; a second coil spring 509, the second coil spring 509 is provided inside the sliding frame 503, and the second coil spring 509 is connected to the paddle 508.

[0047] Specifically, by setting the sliding frame 503, when the metal sheet 7 needs to be inserted into the lower end of the heating tube 6, the metal sheets 7 can be stacked and placed at one end of the sliding frame 503, and the metal sheet 7 on the top layer is flush with the sliding frame 503. Then, the sliding frame 503 is started, and the sliding frame 503 moves toward the metal sheet 7 on the top layer. Then, the paddle 508 will first contact the metal sheet 7. However, due to the large mass of the metal sheet 7, the paddle 508 will retract into the interior of the sliding frame 503. When the paddle 508 moves to no longer contact the metal sheet 7, the second coil spring 509 will release its elastic force, and finally the belt The movable paddle 508 is reset, and since there are protrusions on the surface of the metal sheet 7, the metal sheet 7 can be moved to the track inside the sliding frame 503, and then the sliding frame 503 is started again, the sliding frame 503 will be reset, and when the paddle 508 contacts the metal sheet 7, since the paddle 508 is limited by the sliding frame 503 at this time, it will not rotate, thereby pushing the metal sheet 7 to move toward the welding head 41. At this time, starting the welding module 4 can drive the metal sheet 7 to move upward and perform welding. When welding is needed again, the stacked metal sheets 7 can be lifted up for a certain distance.

[0048] like Figures 9 to 13 As shown, the loading structure 5 also includes: a sliding rail 502, the sliding rail 502 is arranged on the surface of the base frame 1, and the sliding frame 503 slides on the surface of the sliding rail 502; a storage frame 501, the storage frame 501 is arranged at one end of the base frame 1 close to the welding module 4; a placement plate 507, and a plurality of placement plates 507 are rotatably connected to the inside of the storage frame 501.

[0049] Specifically, when it is necessary to insert the metal sheet 7 into the lower end of the heating tube 6, firstly, several metal sheets 7 are stacked and placed inside the storage frame 501, and each metal sheet 7 will be located at the upper end of the placement plate 507. When it is necessary to load the metal sheet 7, start the sliding frame 503, and the sliding frame 503 will slide on the surface of the sliding rail 502. When welding is needed again, it is only necessary to push the bottom metal sheet 7 upward. At this time, the metal sheet 7 will move upward as a whole, and in the process of movement, the placement plate 507 will be pushed open, causing the placement plate 507 to rotate, and finally each metal sheet 7 will rise, and when the metal sheet 7 is put down, since a limit block is provided under the placement plate 507, it will not rotate in the opposite direction, and finally each metal sheet 7 can be transferred upward.

[0050] like Figures 9 and 10 As shown, a pressing plate 505 is rotatably connected to the surface of the sliding frame 503 , and a first coil spring 506 is disposed on the side wall of the pressing plate 505 .

[0051] Specifically, by setting the pressing plate 505, when the metal sheet 7 moves into the sliding frame 503, the first coil spring 506 releases the elastic force, and the pressing plate 505 will slightly fix the metal sheet 7 so that the metal sheet 7 will not deviate, thereby affecting subsequent welding.

[0052] like Figures 11 to 13 As shown, an anti-deflection plate 510 is provided on the surface of the placement plate 507 , and the upper end of the anti-deflection plate 510 is inclined toward the direction close to the outer wall of the storage frame 501 .

[0053] Specifically, by setting the anti-deflection plate 510, when the entire metal sheet 7 in the storage frame 501 is transferred upward, if one end of the metal sheet 7 is offset, it will fall on the surface of the anti-deflection plate 510. Since the lower end of the anti-deflection plate 510 is inclined toward the direction close to the metal sheet 7, the metal sheet 7 will slide down at this time and eventually move to the most central position for subsequent loading.

[0054] like Figures 9 to 13 As shown, a pad 511 is slidably connected to the bottom of the storage frame 501 , and a connecting rod 504 is provided at one end of the pad 511 close to the welding module 4 , and the connecting rod 504 is connected to the welding module 4 .

[0055] Specifically, since the welding module 4 will move upward for a distance during welding, by providing a connecting rod 504, the connecting rod 504 can drive the pad 511 to move together during welding, and finally the pad 511 drives the metal sheet 7 to move upward as a whole.

[0056] Working principle: When welding of the coffee machine heating element is required, firstly, a plurality of metal sheets 7 are stacked and placed inside the storage frame 501, and each metal sheet 7 is located at the upper end of the placement plate 507. When the metal sheets 7 need to be loaded, the sliding frame 503 is started, and the sliding frame 503 slides on the surface of the sliding rail 502. Then, the paddle 508 first contacts the metal sheet 7. However, due to the large mass of the metal sheet 7, the paddle 508 is retracted into the interior of the sliding frame 503. When the paddle 508 moves to no longer contact the metal sheet 7, the second coil spring 509 releases its elastic force, and finally drives the paddle 508 to reset. Moreover, since the surface of the metal sheet 7 is provided with a protrusion, the metal sheet 7 can be moved to The sliding frame 503 is then started again, the sliding frame 503 will be reset, and when the paddle 508 contacts the metal sheet 7, the paddle 508 will not rotate because it is limited by the sliding frame 503 at this time, thereby pushing the metal sheet 7 to move toward the welding head 41, and then the straight part of the heating tube 6 is placed between the adjusting buckle 312 and the movable buckle 313. Due to the squeezing of the heating tube 6, the adjusting buckle 312 and the movable buckle 313 will move away from the heating tube 6. At this time, the compression spring 314 at one end of the movable buckle 313 is releasing its elastic force, and the reset spring 311 between the first sliding plate 309 and the second sliding plate 310 is also releasing its elastic force. The heating tube 6 can be clamped, and then the metal sheet 7 is placed under the heating tube 6 and moved upward so that the metal sheet 7 passes through the heating tube 6. At this time, the welding machine inside the welding module 4 is started. The welding method of the welding machine is arc welding. Then the welding head 41 will move upward and finally contact the welding part. When it contacts the surface of the metal sheet 7, the welding head 41 will move downward quickly to form an arc discharge. Then, through multiple repeated operations, and gradually adding welding wire to the welding part during the welding process, a cladding layer is formed. The cladding layer will be mixed with the molten metal on the surface of the metal sheet 7 to achieve the connection between the metal sheet 7 and the heating tube 6. However, during the welding process, if the heating tube 6 and the metal sheet 7 are not perpendicular to each other, the integrity of the structure will be reduced. The stability of the body may cause the heating tube 6 to become loose or deformed during long-term use, causing safety hazards. For this reason, an abutment rod 317 is designed. Since the equipment will be transferred through the turntable 2 after welding, continuous welding work can be performed. When the turntable 2 moves the welded heating tube 6 to just above the support plate 316, the support plate 316 is started and the support plate 316 will move upward. When the metal sheet 7 is perpendicular to the heating tube 6, the abutment rods 317 distributed at the four corners of the support plate 316 will eventually abut against the lower surface of the metal sheet 7. At this time, the sliding rack 320 will also move to a position meshing with the lower gear 303. When the turntable 2 continues to rotate, the lower gear 303 will mesh with the sliding rack 320.And the lower gear 303 will also drive the upper gear 307 to rotate together. At this time, the upper gear 307 will drive the second rack 308 to move, so that the active buckle 313 and the adjustment buckle 312 move away from each other, and finally the heating tube 6 is no longer clamped, so that it falls off for subsequent collection. When the metal sheet 7 and the heating tube 6 are not perpendicular to each other, the abutment rod 317 will contact the downwardly inclined end of the metal sheet 7 in advance, and finally the sliding rack 320 will not move to a position flush with the lower gear 303, and finally the active buckle 313 and the adjustment buckle 312 will not be opened, and finally the heating tube 6 will not fall off. This heating tube 6 that cannot automatically fall off is a product with unqualified welding and needs to be discarded.

[0057] The above shows and describes the basic principles, main features and advantages of the present invention.
