Description

Technical Field

[0001] The present invention relates to the field of welding technology, and particularly to a bimetal sheet processing and welding device. Background Art

[0002] A bimetal sheet is a composite material in which two metal sheets with different thermal expansion coefficients are firmly bonded together along the layer interface. Welding is a common connection method for bimetal sheets. Through resistance welding, atomic bonding is achieved at the contact surface of the two metal sheets, thereby ensuring the strength and stability of the connection. During long-term welding operations, problems such as wear, depression, and oxidation may occur on the surface of the electrodes, resulting in a reduction in the contact area between the electrodes and the metal sheet and an increase in the contact resistance. As a result, the current is concentrated locally, leading to uneven welding of the bimetal sheet. At this time, it is necessary to grind the electrodes of the resistance welding to remove the surface irregularities and oxides, restore good contact, and ensure that the current passes through the welding area evenly and stably. When grinding the electrodes, most of the time, it is decided whether to grind the electrodes through manual observation and judgment. When problems such as appearance defects at the welding points, a decrease in welding strength, or unstable welding current are found, manual judgment will determine that electrode grinding is required. However, this method has certain subjectivity and lag, which may lead to the production of a certain number of unqualified products before the problems are discovered, resulting in an unstable overall welding quality.

[0029] To make the above objects, features and advantages of the present invention more obvious and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings of the specification.

[0030] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0031] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure or characteristic that can be included in at least one implementation manner of the present invention. The appearances of "in one embodiment" in different places in this specification do not all refer to the same embodiment, nor are they separate or alternative embodiments that exclude each other with other embodiments.

[0032] Embodiment 1

[0033] Refer to Figures 3 - 7, which is the first embodiment of the present invention. This embodiment provides a bimetal sheet processing and welding device. The bimetal sheet processing and welding device includes a grinding assembly 200, which includes a rotating sleeve 201a, a grinding sleeve 201b, a clamping block 201c, a fixing column 201d, a pressing plate 201e, a counterweight 201f, a force-bearing sleeve 201g, and a first spring 201h. The grinding sleeve 201b is located inside the rotating sleeve 201a. One side of the clamping block 201c is fixed to the grinding sleeve 201b. A clamping groove 201a-1 is formed inside the rotating sleeve 201a, and the clamping block 201c slides inside the clamping groove 201a-1. The fixing column 201d is fixed inside the rotating sleeve 201a. The pressing plate 201e is hinged to the fixing column 201d through a hinge seat. The counterweight 201f is fixed to one side of the pressing plate 201e. The force-bearing sleeve 201g is fixed to the bottom of the grinding sleeve 201b. Both ends of the first spring 201h are fixed to the inner wall of the grinding sleeve 201b and the rotating sleeve 201a respectively.

[0034] The inside of the grinding sleeve 201b has a grinding effect, and the fineness of the internal grinding can be set according to the actual situation. The grinding sleeve 201b is connected to the rotating sleeve 201a through the cooperation of the clamping block 201c and the clamping groove 201a-1, so that the rotating sleeve 201a can drive the grinding sleeve 201b to rotate when rotating, and the grinding sleeve 201b can also move up and down inside the rotating sleeve 201a.

[0035] There are multiple pressing plates 201e, which are evenly distributed in a ring outside the fixing column 201d. The bottom of the force-bearing sleeve 201g contacts the pressing plate 201e. The force-bearing sleeve 201g is inclined in the initial state and fits with the fixing column 201d. The weight of the end of the pressing plate 201e is increased by the counterweight 201f.

[0036] When the rotating sleeve 201a rotates, it will drive the fixing column 201d to rotate at the same time. At this time, the centrifugal force generated by the fixing column 201d will make the pressing plate 201e rotate to a horizontal state, and push the force-bearing sleeve 201g to move through the pressing plate 201e, so that the force-bearing sleeve 201g drives the grinding sleeve 201b to move outward from the rotating sleeve 201a, and the grinding sleeve 201b is sleeved outside the electrode 104. At the same time, as the grinding sleeve 201b rotates, the electrode 104 can be ground.

[0037] When the rotating sleeve 201a stops rotating and the centrifugal force disappears, the first spring 201h can apply a pulling force to the grinding sleeve 201b, so that the grinding sleeve 201b enters the rotating sleeve 201a and separates from the outside of the electrode 104, so that the rotating sleeve 201a can move to one side without affecting the use of the electrode 104.

[0038] Except for the rotating sleeve 201a, there are two sets of grinding components 200, which are respectively located above and below the inside of the rotating sleeve 201a. The upper and lower electrodes 104 can be ground simultaneously by the two sets of grinding components 200.

[0039] The driving component 300 is arranged on one side of the grinding component 200 and includes a fixed sleeve 301a, an airbag 301b, an air outlet pipe 301c, a first connecting pipe 301d, a support sleeve 301e, a stress piece 301f and a second connecting pipe 301g. The fixed sleeve 301a is located on one side of the rotating sleeve 201a. The airbag 301b is arranged inside the fixed sleeve 301a. The air outlet pipe 301c is fixed to the bottom of the fixed sleeve 301a and is communicated with the airbag 301b. The first connecting pipe 301d is fixed to one side of the air outlet pipe 301c. The support sleeve 301e is rotatably connected to the outside of the rotating sleeve 201a through a bearing. The stress piece 301f is fixed to the outside of the rotating sleeve 201a. Both ends of the first connecting pipe 301d are communicated with the air outlet pipe 301c and the support sleeve 301e respectively. The two first connecting pipes 301d are respectively arranged at the bottom and top of the support sleeve 301e and are communicated with the support sleeve 301e.

[0040] The airbag 301b can store gas. There are multiple stress pieces 301f, which are fixedly arranged in a ring on the outside of the rotating sleeve 201a. The middle position of the first connecting pipe 301d is a telescopic corrugated pipe.

[0041] When the support sleeve 301e drives the rotating sleeve 201a to move between the two electrodes 104, the gas inside the airbag 301b at this time will enter the support sleeve 301e through the air outlet pipe 301c and the first connecting pipe 301d, and the stress piece 301f will be pushed to move by the gas, so that the stress piece 301f can drive the rotating sleeve 201a to rotate.

[0042] The second connecting pipe 301g is L-shaped and is used to discharge the gas inside the support sleeve 301e and blow it into the inside of the grinding sleeve 201b, so as to blow out the debris generated by grinding inside the grinding sleeve 201b and clean the debris at the end of the electrode 104 at the same time, thereby avoiding the debris after grinding from adhering to the surface of the electrode 104.

[0043] Embodiment 2

[0044] Refer to Figures 4 - 11 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0045] Specifically, a support rod 302a is fixed to one side of the support sleeve 301e. A support frame 302b is sleeved outside the support rod 302a. The fixed sleeve 301a is fixed to the top of the support frame 302b. A third connecting pipe 302c is fixed to one side of the support frame 302b. One end of the third connecting pipe 302c is communicated with the air outlet pipe 301c. A fourth connecting pipe 302d is inserted into the support rod 302a. The fourth connecting pipe 302d is communicated with the third connecting pipe 302c. A second spring 302e is fixed to one side of the support rod 302a. One end of the second spring 302e is fixed to the inner wall of the support frame 302b.

[0046] The support frame 302b is fixed to one side of the machine body 101. The support sleeve 301e is supported by the cooperation of the support rod 302a and the support frame 302b. The fourth connecting pipe 302d is movably connected inside the support rod 302a.

[0047] When the gas inside the airbag 301b enters the air outlet pipe 301c, it will first enter the inside of the third connecting pipe 302c through the air outlet pipe 301c and enter the fourth connecting pipe 302d through the third connecting pipe 302c. At this time, the gas inside the fourth connecting pipe 302d will push the support rod 302a to move, so that the support sleeve 301e and the rotating sleeve 201a can be driven by the support rod 302a to move between the two electrodes 104.

[0048] A slider is fixed to one side of the support rod 302a. A sliding groove is formed on the support frame 302b. When the support rod 302a moves, it will drive the slider to slide in the sliding groove. When the slider contacts the end of the inner wall of the sliding groove, the support rod 302a can no longer move, and then the rotating sleeve 201a can be stopped between the electrodes 104.

[0049] At the same time, the gas inside the fourth connecting pipe 302d will continuously exert a thrust on the support rod 302a, so that the rotating sleeve 201a can always maintain its current position. When the gas inside the fourth connecting pipe 302d disappears, the support rod 302a and the rotating sleeve 201a can be driven by the second spring 302e to reset.

[0050] Specifically, a fixing plate 303a is fixed inside the air outlet pipe 301c. A first baffle 303b is hinged to the bottom of the fixing plate 303a through a hinge seat. A limiting plate 303c is inserted into the air outlet pipe 301c. A positioning frame 303d is fixed to the bottom of the fixed sleeve 301a. The limiting plate 303c is movably connected inside the positioning frame 303d.

[0051] The fixing plate 303a is provided with ventilation grooves, and the ventilation grooves are blocked by the first baffle 303b to prevent the gas filled inside the airbag 301b from discharging outward randomly. The limiting plate 303c contacts the bottom of the first baffle 303b to limit the first baffle 303b and prevent the first baffle 303b from opening downward under the thrust of the gas.

[0052] The rotating shaft on the hinge seat is fixed inside the first baffle 303b. One side of the hinge seat is fixed with a first torsion spring. One end of the first torsion spring is fixed to the rotating shaft on the hinge seat. After the first baffle 303b is opened, when the gas inside the airbag 301b is completely released, the first torsion spring can apply an upward torsional force to the first baffle 303b, and make the first baffle 303b fit with the bottom of the fixing plate 303a, so as to block the gas inside the airbag 301b again.

[0053] The end of the limiting plate 303c is inclined. After the first baffle 303b is opened and the limiting plate 303c is reset, when the first baffle 303b rotates upward, the inclined surface of the limiting plate 303c can be squeezed to move it to one side, so as not to hinder the first baffle 303b from fitting with the bottom of the fixing plate 303a.

[0054] The positioning frame 303d is used to support and position the limiting plate 303c to prevent it from shifting during movement. A connecting block is fixed to the top of the limiting plate 303c, and a seventh spring is fixed to one side of the connecting block. One end of the seventh spring is fixed to the positioning frame 303d. The seventh spring applies an elastic force to the connecting block, and drives the limiting plate 303c to move through the connecting block, so that it can reset after moving.

[0055] Specifically, a movable plate 304a is arranged inside the fixing sleeve 301a. A push rod 304b is fixed to one side of the movable plate 304a. An extrusion rod 304c is arranged on one side of the fixing sleeve 301a. A force receiving groove 303c-1 is opened on the limiting plate 303c. The top of the extrusion rod 304c is threadedly connected with a threaded rod 304d, and a force receiving plate 304e is rotatably connected to the outside of the threaded rod 304d through a bearing.

[0056] A through groove is opened on the fixing sleeve 301a, and the push rod 304b slides in the through groove. The bottom of the movable plate 304a contacts the airbag 301b. A pressing block is fixed to the top of the movable plate 304a to make the movable plate 304a have a certain weight. The bottom end of the extrusion rod 304c is inclined on one side.

[0057] When the airbag 301b is filled with gas, the inflated airbag 301b will push the movable plate 304a upward. When the movable plate 304a moves upward by a certain height, it will drive the push rod 304b to contact the force-bearing plate 304e and push the force-bearing plate 304e upward, causing the force-bearing plate 304e to drive the extrusion rod 304c upward. The bottom end of the extrusion rod 304c squeezes the inner wall of the force-bearing groove 303c-1 through the inclined surface, and the cooperation of the two can drive the limiting plate 303c to move, so that the limiting plate 303c can release the restriction on the first baffle 303b, and then the first baffle 303b can be opened downward, and the gas inside the airbag 301b can be released outward.

[0058] A plurality of guide frames are fixed on one side of the fixed sleeve 301a. The extrusion rod 304c is movably connected inside the guide frame. A convex block is fixed on one side of the extrusion rod 304c, and the bottom of the convex block contacts the guide frame to limit the extrusion rod 304c to prevent it from falling downward.

[0059] When the push rod 304b contacts the force-bearing plate 304e, it will grind the electrode 104. The height of the force-bearing plate 304e can be adjusted by rotating the threaded rod 304d to drive the force-bearing plate 304e to move up and down, so as to adjust the contact time between the push rod 304b and the force-bearing plate 304e, and then the electrode 104 can be ground at the appropriate time.

[0060] Specifically, an air inlet pipe 305a is fixed on one side of the fixed sleeve 301a. The air inlet pipe 305a is communicated with the airbag 301b. A piston 305b is movably connected inside the air inlet pipe 305a. A ventilation hole 305b-1 is opened on the piston 305b. The bottom of the piston 305b is hinged with a second baffle 305c through a hinge seat. A fixed ring 305d is fixed inside the air inlet pipe 305a and below the piston 305b, and a third baffle 305e is arranged at the bottom of the fixed ring 305d.

[0061] When the piston 305b moves downward, the second baffle 305c will block the ventilation hole 305b-1. At this time, the piston 305b will push the gas downward and push the third baffle 305e downward to open, so as to fill the gas into the airbag 301b. When the piston 305b moves upward, the third baffle 305e will fit upward with the fixed ring 305d to block the gas inside the airbag 301b from discharging outward, and the second baffle 305c will open downward to allow the gas to enter between the piston 305b and the third baffle 305e. When the piston 305b moves downward again, the airbag 301b can be filled with gas again, and then the airbag 301b can expand.

[0062] The rotating shaft on the hinge seat is fixed to the second baffle 305c. A second torsion spring is fixed to one side of the hinge seat. One end of the second torsion spring is fixed to the rotating shaft on the hinge seat. When the piston 305b moves downward, an upward torsional force can be applied to the second baffle 305c through the second torsion spring, so that the second baffle 305c can be attached to the bottom of the piston 305b and block the ventilation holes 305b-1.

[0063] Specifically, a fixing rod 306a is fixed to the top of the piston 305b. A fixing block 306b is fixed to the top end of the fixing rod 306a. A fourth spring 306c is fixed to the bottom of the fixing block 306b. A pressing rod 306d is arranged above the fixing block 306b.

[0064] The pressing rod 306d is L-shaped and is fixed to one side of the movable arm 103. When the movable arm 103 moves downward, it will drive the pressing rod 306d to press the fixing block 306b downward, and drive the fixing rod 306a and the piston 305b to move downward through the fixing block 306b, so as to fill the inside of the airbag 301b with gas. When the movable arm 103 moves upward, the fixing block 306b can be pushed upward by the fourth spring 306c, and the fixing rod 306a and the piston 305b can be driven by the fixing block 306b to reset upward. As the movable arm 103 continuously moves up and down, the inside of the airbag 301b can be continuously filled with gas. When the electrode 104 is used a certain number of times and needs to be ground, the airbag 301b will push the movable plate 304a upward by a specified height and make the push rod 304b push the force-receiving plate 304e upward.

[0065] Embodiment 3

[0066] Refer to Figures 1 - 11 , which is the third embodiment of the present invention. This embodiment is based on the first two embodiments.

[0067] Specifically, a positioning column 305f is fixed to the bottom of the third baffle 305e. A stabilizing frame 305g is fixed inside the air inlet pipe 305a. A fifth spring 305h is fixed to the bottom of the third baffle 305e. One end of the fifth spring 305h is fixed to the stabilizing frame 305g.

[0068] Through the cooperation of the positioning column 305f and the stabilizing frame 305g, it is used to position the third baffle 305e. The fifth spring 305h is used to apply a thrust to the third baffle 305e so that it can reset after moving.

[0069] Specifically, a support ring 307a is fixed inside the first connecting pipe 301d. A fourth baffle 307b is arranged on one side of the support ring 307a. A stabilizing column 307c is fixed to one side of the fourth baffle 307b. A positioning frame 307d is fixed inside the first connecting pipe 301d. A sixth spring 307e is fixed to one side of the positioning frame 307d.

[0070] The inside of the first connecting pipe 301d is blocked by the fourth baffle 307b, so that the gas inside the air outlet pipe 301c first enters the third connecting pipe 302c. Only when the support rod 302a cannot move further, the gas will push the fourth baffle 307b to move at this time, and then the gas can enter the first connecting pipe 301d.

[0071] Through the cooperation of the stabilizing column 307c and the positioning frame 307d, the fourth baffle 307b is positioned to prevent it from shifting when moving. A thrust is applied to the fourth baffle 307b by the sixth spring 307e, so that the fourth baffle 307b will not open when initially subjected to the pressure of the gas. Only when the gas cannot enter the inside of the third connecting pipe 302c, the gas will push the fourth baffle 307b to open.

[0072] The elastic force of the sixth spring 307e is slightly greater than the elastic force of the second spring 302e, so the second spring 302e will be stretched first.

[0073] Specifically, a plug 301c-1 is threadedly connected to the bottom of the air outlet pipe 301c.

[0074] By removing the plug 301c-1, the gas inside the airbag 301b can be emptied in advance, thereby avoiding the situation that the grinding time of the electrode 104 is too long.

[0075] Specifically, it further includes a main body assembly 100, which is arranged on one side of the grinding assembly 200 and includes a machine body 101, a support arm 102, a movable arm 103, an electrode 104, a rotary table 105 and a positioning fixture 106. The machine body 101 is arranged on one side of the fixed sleeve 301a, the support arm 102 is fixed to one side of the machine body 101, the movable arm 103 is arranged on the machine body 101, two electrodes 104 are respectively fixed to the movable arm 103 and the support arm 102, the rotary table 105 is located on one side of the machine body 101, and the positioning fixture 106 is arranged on the rotary table 105.

[0076] The movable arm 103 is used to drive the electrode 104 to move up and down, so that the upper and lower electrodes 104 can weld the bimetal sheet in the middle. The number of times the movable arm 103 moves up and down is the number of times the electrode 104 welds the bimetal sheet. There are multiple positioning fixtures 106, which are evenly distributed in a ring on the rotary table 105. The positioning fixture 106 is used to position the bimetal sheet to be welded. The bimetal sheet can be placed in the positioning fixture 106 by a robotic arm or manually, and the rotary table 105 drives the positioning fixture 106 to rotate, and the positioned bimetal sheet is rotated between the two electrodes 104. At this time, the bimetal sheet can be welded by the electrode 104.

[0077] The positioning fixture 106 and the rotary table 105 are prior arts, so they will not be elaborated in this solution. Those skilled in the art can select the appropriate positioning fixture 106 and rotary table 105 according to the actual situation, which is common general knowledge for those skilled in the art.

[0078] In summary, the bimetal processing and welding equipment of the present invention has the following advantages:

[0079] First, there is no need for manual observation of the usage of the electrode 104, and it can be automatically ground after the electrode 104 has been used a certain number of times.

[0080] Second, the frequency of the grinding times of the electrode 104 can be adjusted, so that the electrode 104 can be ground at an appropriate time, avoiding premature or too late grinding, which will affect the normal use of the electrode 104.

[0081] Third, the grinding duration of the electrode 104 can be controlled. If it is considered that the electrode 104 is over-ground, it can be ended in advance.

[0082] Fourth, the ground electrode 104 can be cleaned to avoid the situation that the debris after grinding adheres to the surface of the electrode 104.

[0083] During use, the bimetal is placed in the positioning fixture 106 by a robotic arm or manually, and the positioning fixture 106 is rotated by the rotary table 105 to rotate the positioned bimetal between the two electrodes 104. Then, the movable arm 103 drives the electrode 104 to move downward, so that the upper and lower electrodes 104 can weld the bimetal in the middle. When the movable arm 103 moves downward, it will drive the pressing rod 306d to press the fixed block 306b downward, and drive the fixed rod 306a and the piston 305b to move downward through the fixed block 306b, so as to inject gas into the airbag 301b, causing the airbag 301b to expand and store the gas.

[0084] The expanded airbag 301b will push the movable plate 304a to move upward. When the movable arm 103 drives the electrode 104 to move up and down a certain number of times and the end of the electrode 104 is worn, at this time, the movable plate 304a moves upward a certain height, driving the push rod 304b to contact the force-receiving plate 304e and pushing the force-receiving plate 304e to move upward, so that the force-receiving plate 304e drives the extrusion rod 304c to move upward, and the inner wall of the force-receiving groove 303c-1 is extruded through the inclined surface at the bottom of the extrusion rod 304c. Through the cooperation of the two, the limiting plate 303c can be driven to move, so that the limiting plate 303c releases the restriction on the first baffle 303b, and then the first baffle 303b can be opened downward, and the gas inside the airbag 301b is released outward.

[0085] When the gas inside the airbag 301b enters the air outlet pipe 301c, it will first enter the inside of the third connecting pipe 302c through the air outlet pipe 301c and enter the fourth connecting pipe 302d through the third connecting pipe 302c. At this time, the gas inside the fourth connecting pipe 302d will push the support rod 302a to move, so that the support sleeve 301e and the rotating sleeve 201a can be driven by the support rod 302a to move between the two electrodes 104.

[0086] Meanwhile, the gas inside the airbag 301b will enter the support sleeve 301e through the air outlet pipe 301c and the first connecting pipe 301d, and push the force-receiving piece 301f to move through the gas, so that the force-receiving piece 301f can drive the rotating sleeve 201a to rotate. When the rotating sleeve 201a rotates, it will drive the fixed column 201d to rotate at the same time. At this time, the centrifugal force generated by the fixed column 201d will make the pressing plate 201e rotate to the horizontal state, and push the force-receiving sleeve 201g to move through the pressing plate 201e, so that the force-receiving sleeve 201g drives the grinding sleeve 201b to move outward from the rotating sleeve 201a, and the grinding sleeve 201b is sleeved outside the electrode 104. Meanwhile, as the grinding sleeve 201b rotates, the electrode 104 can be ground.

[0087] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
