Description

Technical Field

[0001] The present invention relates to the technical field of welding equipment, in particular to a fuse melt precision spot welding device. Background Art

[0002] A fuse is an electrical component used for circuit protection. Fuses are generally cylindrical in shape. When a circuit fault such as overload or short circuit occurs, causing the current to exceed the rated current of the fuse, the fuse element will melt due to overheating, thereby cutting off the circuit and protecting other electrical equipment in the circuit. It is the core component of the fuse, usually made of metal materials with low melting point and high conductivity, such as lead, tin, zinc and other alloys. When the current is too large, the fuse element will first heat up and melt. When manufacturing fuses, the fuse element needs to be welded, so welding equipment is required. Fuse melt precision spot welding equipment is a device used to perform high-precision and high-quality welding of the fuse element and other components.

[0003] At present, the traditional spot welding of fuse melt is easily affected by the external temperature, especially in cold weather conditions in the north. When the external temperature is low, the heat of spot welding dissipates quickly and the heat loss is large, which makes it difficult to form a molten core. It is necessary to increase the welding energy and extend the welding time to ensure the welding quality, consume more energy, and is not conducive to energy saving and environmental protection.

[0009] The protective assembly includes a guide rod and a protective cover, the guide rod is fixedly mounted on the surface of the spot welding head, the protective cover is slidably mounted between the guide rod and the surface of the spot welding head, an observation window is fixedly mounted on the side of the surface of the protective cover, the edge line of the bottom of the protective cover is fixedly connected to the limiting plug rod, and a hose is connected between the surface of the protective cover and the air inlet of the fan. When the welding host and the spot welding head move downward, the protective cover will move downward with the spot welding head, and use the bottom end of the spot welding head to pass through the top of the protective cover. The protective cover surrounds the spot welding head, so that when the spot welding head welds the fuse melt, heat is not easily dissipated, which has a heat preservation effect and is not easily affected by external low temperatures, making it convenient to form a material molten core, which helps to improve the welding quality.

[0010] Preferably, the hydraulic cylinder is installed vertically, there are two hydraulic cylinders, and the two hydraulic cylinders are installed symmetrically along the welding main machine, and the right-angle pipe connects the fume treatment box with the fan.

[0011] Preferably, there are three guide rods, and the three guide rods are evenly distributed along the circumferential direction of the axis in the middle of the spot welding head. The protective cover is conical, and the diameter of the protective cover gradually increases from top to bottom. By covering the surface of the spot welding head with the protective cover, the exhaust gas generated by welding can be covered, and the welding slag can be shielded, so that the welding slag is not easy to splash, which is safe and reliable.

[0012] Preferably, the observation window is made of tempered glass, the limiting rods are installed vertically, there are three limiting rods, and the three limiting rods are evenly distributed at the edge of the bottom of the protective cover.

[0013] By utilizing the suction force generated by the fan and combining a hose to connect the protective cover to the fan, the welding exhaust gas enclosed in the protective cover can be sucked out and transported through the right-angle pipe to the inside of the fume treatment box, so that the welding exhaust gas can be treated, the emission of exhaust gas can be reduced, and it is helpful to environmental protection.

[0014] Preferably, the circulation mechanism includes a cross rotating frame, which is rotatably installed in the middle of the top of the machine body, a circular hole is opened on the side of the top of the cross rotating frame, and a U-shaped notch is opened on the edge of the surface of the cross rotating frame.

As the fuse melt to be welded falls into the inside of the circular hole, the bottom end of the fuse melt contacts the bottom of the inner side surface of the right-angled lifting piece, so that the fuse melt can be initially limited, and it is not easy to deviate or fall off.

[0015] Preferably, there are four circular holes, and the four circular holes are evenly distributed on the sides of the top of the cross rotating frame, and the opening of the U-shaped notch faces the side away from the circular hole. By moving the protective cover downward, the limiting rod can be driven to move downward, so that the bottom end of the limiting rod is inserted into the inside of the U-shaped notch. The guiding and limiting of the limiting rod make the protective cover less likely to shake, and the spot welding head passes through the center of the protective cover so that the spot welding head is supported by the protective cover, so that the spot welding head has good overall stability when welding the fuse melt, thereby facilitating precision spot welding, and utilizing the interaction between the structures to connect the structures together.

[0016] Preferably, the arc-shaped pressure guide rail is installed directly below the U-shaped notch, and the arc-shaped pressure guide rail is installed at an angle, inserted into the interior of the U-shaped notch through a limiting rod, and as the limiting rod continues to move downward, the bottom end of the limiting rod fits into the groove at the top of the arc-shaped pressure guide rail, and the arc-shaped pressure guide rail is pressed by the limiting rod. The arc-shaped pressure guide rail applies pressure to the right-angled lifting piece, and under the elastic connection of the elastic connecting piece, the elastic deformation of the elastic connecting piece is utilized to make the right-angled lifting pieces evenly distributed at the bottom of the circular hole shrink inward, so that the fuse melt can be clamped and fixed by the elastic clamping strip, so that the fuse melt is not easy to be skewed, and the structure is fully connected together.

[0017] Preferably, a feeding mechanism is installed at the side of the top of the machine body, and the feeding mechanism includes an F-shaped bracket and a connecting shaft, the bottom of the F-shaped bracket is fixedly connected to the side of the top of the machine body and one end away from the machine head by a bolt, the bottom end of the connecting shaft is rotatably installed between the top of the machine body, the top of the F-shaped bracket is fixedly connected to a storage barrel, the top of the connecting shaft is fixedly connected to an arc-shaped blocking plate, a torque spring is fixedly connected between the top of the machine body and the bottom of the arc-shaped blocking plate, a leakage hole is opened at the side of the top of the arc-shaped blocking plate, and a force-bearing plate is fixedly connected to the side of the bottom of the arc-shaped blocking plate, so that the fuse melt that needs spot welding is placed inside the storage barrel, and the storage barrel is stored, which is conducive to subsequent continuous loading and convenient for batch welding processing;

[0018] As the cross rotating frame rotates, the edge of the cross rotating frame contacts the surface of the force-bearing plate, so that the force-bearing plate is subjected to a driving force, and under the rotation support of the connecting shaft, the arc-shaped sealing plate is driven to rotate counterclockwise, and the torque spring is elastically deformed by the torque force, and moves toward the discharge port position at the bottom end of the storage barrel as the leakage hole moves, and the circular hole is driven by the cross rotating frame to rotate synchronously, so that the leakage hole, the circular hole and the storage barrel can be on the same vertical line, so that the fuse melt material in the storage barrel can pass through the leakage hole and enter the inside of the circular hole, and automatic loading can be carried out.

[0019] Preferably, the storage barrel is installed vertically, the arc-shaped sealing plate is installed directly below the storage barrel, and the top of the arc-shaped sealing plate is in contact with the discharge port at the bottom of the storage barrel, and the force-bearing plate is arc-shaped.

[0020] As the cross rotating frame continues to rotate, the edge of the cross rotating frame is separated from the force plate, the driving force on the force plate disappears, and under the elastic force of the torque spring, the arc-shaped blocking plate rotates clockwise to reset, and the discharge port at the bottom of the storage barrel can be blocked again, stopping the discharge of materials.

[0021] Preferably, the center of the arc-shaped sealing plate coincides with the axis of the connecting shaft, the leakage hole is arc-shaped, and the connecting shaft passes through the center line of the torque spring.

[0022] The present invention provides a precision spot welding device for fuse melt, which has the following beneficial effects:

[0023] 1. This precision spot welding equipment for fuse melts uses the extension and contraction of the telescopic end of the hydraulic cylinder to drive the welding host to move downward and upward, so that the spot welding head is driven to move along with the welding host. Thus, by moving the welding host and the spot welding head together, the height of the spot welding head can be adjusted. This not only facilitates the control of adjusting the spot welding end of the spot welding head to the appropriate distance from the top of the fuse melt to be welded, but also can adapt to fuse melts of different lengths.

[0024] 2. The precision spot welding equipment for fuse melt moves downward through the welding host and the spot welding head. The protective cover moves downward with the spot welding head, and the bottom end of the spot welding head passes through the top of the protective cover. The protective cover surrounds the spot welding head, so that when the spot welding head welds the fuse melt, heat is not easily dissipated, which has a heat preservation effect and is not easily affected by the external low temperature, making it easy to form a material molten core, which helps to improve the welding quality.

[0025] 3. The precision spot welding equipment for fuse melt uses a protective cover on the surface of the spot welding head to cover the exhaust gas generated by welding and shield the welding slag, making it difficult for the welding slag to splash. It is safe and reliable, and the observation window is made of tempered glass, which is transparent and resistant to high temperatures, making it easy to observe the progress of the fuse melt welding process through the spot welding head inside the protective cover.

[0026] Fourth, the fuse melt precision spot welding equipment uses the suction generated by the fan and combines the protective cover with the fan with a hose, so that the welding exhaust gas shrouded in the protective cover is sucked out and transported through the right-angle pipe to the inside of the fume treatment box, so that the welding exhaust gas can be treated, the exhaust gas emission can be reduced, and it is helpful to environmental protection.

[0027] 5. This precision spot welding equipment for fuse melt can initially limit the position of the fuse melt as the fuse melt to be welded falls into the inside of the circular hole, so that the bottom end of the fuse melt contacts the bottom of the inner side of the right-angled lifting piece, making it less likely to deviate or fall off.

[0028] 6. The precision spot welding equipment for fuse melt can drive the limit rod to move downward by moving the protective cover downward, so that the bottom end of the limit rod is inserted into the inside of the U-shaped notch. The protection cover is not easy to shake by using the guidance and limitation of the limit rod. The spot welding head passes through the center of the protection cover, so that the spot welding head is supported by the protective cover, which can make the spot welding head have good overall stability when welding the fuse melt, thereby facilitating precision spot welding.

[0029] 7. The precision spot welding equipment for fuse melt, as the limiting rod continues to move downward, makes the bottom end of the limiting rod fit into the groove on the top of the arc-shaped pressure guide rail, and the arc-shaped pressure guide rail is pressed by the limiting rod. The arc-shaped pressure guide rail applies pressure to the right-angled lifting piece, and under the elastic connection of the elastic connecting piece, the elastic deformation of the elastic connecting piece is utilized to make the right-angled lifting pieces evenly distributed at the bottom of the circular hole shrink inward, and the fuse melt can be clamped and fixed by the elastic clamping strip, so that the fuse melt is not easy to be skewed, and the structure is fully connected together.

[0030] 8. The precision spot welding equipment for fuse melt uses the edge of the cross rotating frame to push the force plate, so that the arc-shaped sealing plate is driven to rotate counterclockwise, and the torque spring is elastically deformed by the torque force, and moves toward the discharge port position at the bottom of the storage barrel along with the movement of the leakage hole, and the circular hole is driven by the cross rotating frame to rotate synchronously, so that the leakage hole, the circular hole and the storage barrel can be on the same vertical line, so that the fuse melt material in the storage barrel can pass through the leakage hole and enter the inside of the circular hole, and automatic loading can be carried out.

[0031] 9. This precision spot welding equipment for fuse melt utilizes the edge of the cross rotating frame to separate from the force-bearing plate. The driving force on the force-bearing plate disappears, and under the elastic force of the torque spring, the arc-shaped sealing plate rotates clockwise to reset, and the discharge port at the bottom of the storage barrel can be sealed again, stopping material discharge.

[0042] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0043] The first embodiment, as Figures 1 to 5 As shown, the present invention provides a technical solution:

[0044] A precision spot welding device for fuse melt, comprising:

[0045] The machine body 1 and the machine head 2 are fixedly mounted on the side of the machine body 1, and the circulation mechanism 3 is installed in the middle of the top of the machine body 1;

[0046] A processing mechanism 4 is used for spot welding the fuse melt and is mounted on the top of the machine head 2;

[0047] Among them, the processing mechanism 4 includes a hydraulic cylinder 41 and a fan 42, which are sequentially installed on the top of the machine head 2, and the telescopic end of the hydraulic cylinder 41 is fixedly connected to the welding host 43, and a spot welding head 44 is installed in the middle of the bottom of the welding host 43. A protective component 45 is installed on the surface of the spot welding head 44, and a fume treatment box 46 is fixedly installed in the middle of the surface of the machine head 2. A right-angle pipe 47 is installed between the top of the fume treatment box 46 and the air outlet of the fan 42. The staff starts the hydraulic cylinder 41 to work. With the support of the machine head 2 on the hydraulic cylinder 41, the extension and contraction of the telescopic end of the hydraulic cylinder 41 can drive the welding host 43 to move downward and upward, so that the spot welding head 44 is driven to move with the welding host 43, thereby moving the welding host 43 and the spot welding head 44 together, and the height of the spot welding head 44 can be adjusted;

[0048] The hydraulic cylinder 41 is installed vertically. There are two hydraulic cylinders 41 , and the two hydraulic cylinders 41 are installed symmetrically along the welding host 43 . The right-angle pipe 47 connects the fume treatment box 46 with the fan 42 .

[0049] The protective assembly 45 includes a guide rod 451 and a protective cover 452. The guide rod 451 is fixedly mounted on the surface of the spot welding head 44. The protective cover 452 is slidably mounted between the guide rod 451 and the surface of the spot welding head 44. An observation window 453 is fixedly mounted on the side of the surface of the protective cover 452. The edge line of the bottom of the protective cover 452 is fixedly connected to the limiting plug rod 454. A hose 455 is connected between the surface of the protective cover 452 and the air inlet of the fan 42. When the welding host 43 and the spot welding head 44 move downward, the protective cover 452 will move downward with the spot welding head 44, and use the bottom end of the spot welding head 44 to pass through the top of the protective cover 452. The protective cover 452 surrounds the spot welding head 44, so that when the spot welding head 44 welds the fuse melt, heat is not easily dissipated.

[0050] There are three guide rods 451, and the three guide rods 451 are evenly distributed along the circumferential direction of the axis in the middle of the spot welding head 44. The protective cover 452 is conical, and the diameter of the protective cover 452 gradually increases from top to bottom. By covering the surface of the spot welding head 44 with the protective cover 452, the exhaust gas generated by welding can be covered, and the welding slag can be shielded, so that the welding slag is not easy to splash, which is safe and reliable. The observation window 453 is made of tempered glass, which is transparent and resistant to high temperatures, so that the progress of the fuse melt welding process can be observed by the spot welding head 44 that passes through the inside of the protective cover 452.

[0051] The material of the observation window 453 is tempered glass, and the limit rod 454 is installed vertically. There are three limit rods 454, and the three limit rods 454 are evenly distributed at the edge of the bottom of the protective cover 452. The staff turns on the fan 42 to work, uses the suction generated by the fan 42, and combines the hose 455 to connect the protective cover 452 with the fan 42, so that the welding exhaust gas shrouded in the protective cover 452 is sucked out and transported through the right-angle pipe 47 to the inside of the fume treatment box 46, so that the welding exhaust gas can be treated.

[0052] The second embodiment, based on the first embodiment, see Figures 1 to 7 As shown:

[0053] The circulation mechanism 3 includes a cross rotating frame 31, which is rotatably mounted in the middle of the top of the machine body 1. A circular hole 32 is opened on the side of the top of the cross rotating frame 31, and a U-shaped notch 33 is opened on the edge of the surface of the cross rotating frame 31. An elastic connecting piece 34 is fixedly connected to the side of the bottom of the cross rotating frame 31, and the bottom end of the elastic connecting piece 34 is fixedly connected to a right-angled lifting piece 35. The inner side of the right-angled lifting piece 35 is fixedly connected to an elastic clamping strip 36, and the middle of the surface of the right-angled lifting piece 35 is fixedly connected to an arc-shaped pressure guide rail 37. As the fuse melt to be welded falls into the inside of the circular hole 32, the bottom end of the fuse melt contacts the bottom of the inner side of the right-angled lifting piece 35, thereby preliminarily limiting the fuse melt.

[0054] There are four circular holes 32, and the four circular holes 32 are evenly distributed on the sides of the top of the cross rotating frame 31. The opening of the U-shaped notch 33 faces the side away from the circular hole 32. By moving the protective cover 452 downward, the limiting rod 454 can be driven to move downward together, so that the bottom end of the limiting rod 454 is inserted into the inside of the U-shaped notch 33. The guiding and limiting of the limiting rod 454 make the protective cover 452 less likely to shake, and the spot welding head 44 passes through the center of the protective cover 452, so that the spot welding head 44 is supported by the protective cover 452.

[0055] The arc-shaped pressure guide rail 37 is installed directly below the U-shaped notch 33, and the arc-shaped pressure guide rail 37 is installed at an angle, and is inserted into the interior of the U-shaped notch 33 through the limiting plug 454. As the limiting plug 454 continues to move downward, the bottom end of the limiting plug 454 fits into the groove at the top of the arc-shaped pressure guide rail 37, and the arc-shaped pressure guide rail 37 is pressed by the limiting plug 454. The arc-shaped pressure guide rail 37 applies pressure to the right-angled lifting piece 35, and under the elastic connection of the elastic connecting piece 34, the elastic deformation of the elastic connecting piece 34 is utilized to make the right-angled lifting pieces 35 evenly distributed at the bottom of the circular hole 32 shrink inward, so that the fuse melt can be clamped and fixed by the elastic clamping strip 36.

[0056] The third embodiment, based on the first and second embodiments, see Figures 1 to 9 As shown:

[0057] A feeding mechanism 5 is installed on the side of the top of the body 1. The feeding mechanism 5 includes an F-shaped bracket 51 and a connecting shaft 52. The bottom of the F-shaped bracket 51 is fixedly connected to the side of the top of the body 1 and one end away from the head 2 by bolts. The bottom end of the connecting shaft 52 is rotatably installed between the top of the body 1. The top of the F-shaped bracket 51 is fixedly connected to a storage barrel 53. The top of the connecting shaft 52 is fixedly connected to an arc-shaped blocking plate 54. A torque spring 55 is fixedly connected between the top of the body 1 and the bottom of the arc-shaped blocking plate 54. A leakage hole 56 is opened on the side of the top of the arc-shaped blocking plate 54. A force plate 57 is fixedly connected to the side of the bottom of the arc-shaped blocking plate 54. The staff places the fuse melt that needs to be spot welded into the storage barrel 53. Inside, the storage barrel 53 is stored, and as the cross-rotating frame 31 rotates, the edge of the cross-rotating frame 31 contacts the surface of the force-bearing plate 57, so that the force-bearing plate 57 is subjected to a driving force, and under the rotation support of the connecting shaft 52, the arc-shaped sealing plate 54 is driven to rotate counterclockwise, and the torque spring 55 is elastically deformed by the torque force, and moves toward the discharge port position at the bottom end of the storage barrel 53 as the leakage hole 56 moves, and the circular hole 32 is driven by the cross-rotating frame 31 to rotate synchronously, so that the leakage hole 56, the circular hole 32 and the storage barrel 53 can be on the same vertical line, so that the fuse melt material in the storage barrel 53 can pass through the leakage hole 56 and enter the inside of the circular hole 32, and automatic loading can be carried out.

[0058] The storage barrel 53 is installed vertically, and the arc-shaped blocking plate 54 is installed directly below the storage barrel 53, and the top of the arc-shaped blocking plate 54 is in contact with the discharge port at the bottom of the storage barrel 53. The force plate 57 is arc-shaped. As the cross-rotating frame 31 continues to rotate, the edge of the cross-rotating frame 31 is separated from the force plate 57, and the driving force on the force plate 57 disappears. Under the elastic force of the torque spring 55, the arc-shaped blocking plate 54 rotates clockwise to reset, and the discharge port at the bottom of the storage barrel 53 can be sealed again.

[0059] The center of the arc-shaped blocking plate 54 coincides with the axis of the connecting shaft 52 . The leakage hole 56 is arc-shaped, and the connecting shaft 52 passes through the center line of the torque spring 55 .

[0060] When in use, the staff first places the fuse melt that needs spot welding into the storage barrel 53, stores the storage barrel 53, and uses the arc-shaped sealing plate 54 to block the discharge port at the bottom of the storage barrel 53, so that the fuse melt material in the storage barrel 53 will not fall out at will;

[0061] At this time, the staff turns on the power source to drive the cross rotating frame 31 to rotate. The edge of the cross rotating frame 31 contacts the surface of the force-bearing plate 57, so that the force-bearing plate 57 is driven by a driving force, and under the rotation support of the connecting shaft 52, the arc-shaped sealing plate 54 is driven to rotate counterclockwise, and the torque spring 55 is elastically deformed by the torque force, and the leakage hole 56 moves toward the discharge port position at the bottom end of the storage barrel 53, and the circular hole 32 is driven by the cross rotating frame 31 to rotate synchronously, so that the leakage hole 56, the circular hole 32 and the storage barrel 53 can be in the same vertical line, so that the fuse melt material in the storage barrel 53 can pass through the leakage hole 56 and enter the inside of the circular hole 32, so that automatic loading can be carried out;

[0062] As the fuse melt to be welded falls into the circular hole 32, the bottom end of the fuse melt contacts the bottom of the inner side of the right-angled lifting member 35, thereby preliminarily limiting the fuse melt.

[0063] By continuously rotating the cross-shaped rotating frame 31, the edge of the cross-shaped rotating frame 31 is separated from the force-bearing plate 57, and the driving force on the force-bearing plate 57 disappears. Under the elastic force of the torque spring 55, the arc-shaped blocking plate 54 rotates clockwise to reset, and the discharge port at the bottom of the storage barrel 53 can be blocked again.

[0064] At the same time, the cross rotating frame 31 is used to drive the fuse melt material in the circular hole 32 to rotate. When the fuse melt material rotates to just below the spot welding head 44, the rotation of the cross rotating frame 31 can be paused, and the staff starts the hydraulic cylinder 41 to work. With the support of the hydraulic cylinder 41 by the head 2, the extension of the telescopic end of the hydraulic cylinder 41 can be used to drive the welding host 43 to move downward, so that the spot welding head 44 is driven to move along with the welding host 43, thereby moving the welding host 43 and the spot welding head 44 together, and the height of the spot welding head 44 can be adjusted. When the spot welding head 44 moves to above the top of the fuse melt material, the work of the hydraulic cylinder 41 can be paused, and the extension of the hydraulic cylinder 41 can be stopped.

[0065] The limiting rod 454 is inserted into the U-shaped notch 33, and as the limiting rod 454 continues to move downward, the bottom end of the limiting rod 454 fits into the groove at the top of the arc-shaped pressure guide rail 37, and the arc-shaped pressure guide rail 37 is pressed by the limiting rod 454. The arc-shaped pressure guide rail 37 applies pressure to the right-angled lifting piece 35, and under the elastic connection of the elastic connecting piece 34, the elastic deformation of the elastic connecting piece 34 causes the right-angled lifting pieces 35 evenly distributed at the bottom of the circular hole 32 to contract inward, so that the fuse element can be clamped and fixed by the elastic clamping strip 36.

[0066] When the protective cover 452 moves downward, the limiting rod 454 is driven to move downward together, so that the bottom end of the limiting rod 454 is inserted into the interior of the U-shaped notch 33. The limiting rod 454 guides and limits the protective cover 452, so that the protective cover 452 is not easily shaken. The spot welding head 44 passes through the center of the protective cover 452, so that the spot welding head 44 is supported by the protective cover 452, and the fuse melt material can be welded using the spot welding head 44.

[0067] The worker turns on the fan 42 and uses the suction force generated by the fan 42. The protective cover 452 is connected to the fan 42 in combination with the hose 455, so that the welding exhaust gas enclosed in the protective cover 452 is sucked out and transported through the right-angle pipe 47 to the interior of the fume treatment box 46, so that the welding exhaust gas can be treated.

[0068] When welding is completed, the welding host 43 and the spot welding head 44 can be driven to move upward by contracting the telescopic end of the hydraulic cylinder 41, and the cross rotating frame 31 can be used to rotate again to move the welded fuse melt out from directly under the spot welding head 44. As the limiting rod 454 moves upward, the pressing force on the arc-shaped pressure guide rail 37 disappears, and under the elastic force of the elastic connecting piece 34, the right-angled lifting piece 35 moves outward, which can loosen the fuse melt and facilitate the external robot equipment to grab and unload the fuse melt. Repeating the above actions can perform cyclic batch welding.
