[0051] like Figures 1 to 10 As shown in FIG. 1 , an embodiment of the portable strip welding device of the present invention is shown. It should be noted that in the description of the present invention, the “right” side is defined as Figure 3 The outside of the paper, the "left" side Figure 3 The inside of the paper, the "front" side Figure 3 On the left side of the paper, the "back" side is Figure 3 On the right side of the paper, the "upper" side is Figure 3 The upper side of the paper, the "lower" side is Figure 3 The bottom side of the paper.

[0052] See also Figures 1 to 4 The portable strip welding device of this embodiment includes a base 1 and a soldering station 2 arranged on one side of the base 1, and the soldering station 2 is arranged on the front end side of the base 1. The soldering station 2 provides the support and background temperature required for welding for the strip to be welded. A first heater is arranged in the soldering station 2, and the first heater is used to heat the soldering station 2 to provide the background temperature required for strip welding. The upper surface of the soldering station 2 is used to place the strip and provide the support required for welding for the strip. Solder is placed in the welding area to be welded on the strip for welding the strip. A welding assembly 3, a clamping assembly 4 and a driving assembly 5 are arranged on the base 1. The welding assembly 3 includes a heating roller 31 and a second heater. The heating roller 31 is located above the soldering station 2 and can roll along the welding area. The second heater is used to heat the heating roller 31 to provide the temperature required for welding to the welding area, so that the solder melts and infiltrates the surface of the strip to achieve strip welding. The clamping assembly 4 is used to apply pressure to the welding assembly 3 so that the heating roller 31 provides a clamping force to the welding area to ensure that there is no false welding. The driving assembly 5 is used to provide driving force to the welding assembly 3, so that the heating roller 31 rolls along the welding area. Through the joint action of the clamping assembly 4 and the driving assembly 5, the heating roller 31 can be rolled through the welding area, thereby completing the strip welding in the welding area and ensuring no false welding.

[0053] Therefore, the portable strip welding device of this embodiment supports the strip through the welding table 2 and provides the background temperature required for welding. Through the joint action of the clamping component 4 and the driving component 5, the heating roller 31 rolls through the welding area of ​​the strip and heats the solder, which can achieve the welding of the strip in the welding area under the clamping state and ensure that there is no false welding. Therefore, the portable strip welding device of this embodiment can complete the strip welding by itself, and does not require an additional fixed welding table, so it can be carried and moved according to the needs of the application scenario, and has the advantages of being portable and movable, easy to operate, easy to use, and having a wide range of application scenarios, and can ensure the welding quality.

[0054] In this embodiment, preferably, the welding assembly 3 includes a heating connecting rod 32, the heating connecting rod 32 is rollably arranged on the base 1, the second heater is arranged in the heating connecting rod 32, the heating roller 31 is arranged at one end of the heating connecting rod 32, and the pressing assembly 4 and the driving assembly 5 both act on the heating connecting rod 32. Specifically, the heating connecting rod 32 is arranged on the upper surface of the front end of the base 1 in the front-to-back direction, and the heating connecting rod 32 can roll in the left-right direction on the base 1. The heating roller 31 is arranged at the front end of the heating connecting rod 32 and is suspended on the front end side of the base 1 and is located above the welding station 2. The pressing assembly 4 acts on the heating connecting rod 32 and applies pressure to the heating connecting rod 32, and the heating roller 31 provides a pressing force to the welding area as the heating connecting rod 32 is pressed down. The driving assembly 5 acts on the heating connecting rod 32 and drives the heating connecting rod 32 to roll in the left-to-right direction on the base 1, and the heating roller 31 rolls along the welding area synchronously with the heating connecting rod 32.

[0055] Preferably, there may be multiple (e.g., two) heating rollers 31, and the multiple heating rollers 31 are arranged side by side in the left-right direction. Correspondingly, there are also multiple heating connecting rods 32, and the multiple heating connecting rods 32 are arranged side by side in the left-right direction on the base 1, and a heating roller 31 is provided at the front end of each heating connecting rod 32. When working, the multiple heating rollers 31 are synchronously rolled in the left-right direction in sequence through the welding area under the joint action of the pressing assembly 4 and the driving assembly 5, and the strip welding in the welding area is completed, which can further ensure the welding quality.

[0056] In this embodiment, preferably, the welding assembly 3 further includes a pressing roller 33, which is arranged in parallel with the heating roller 31 and moves synchronously with the heating roller 31. That is, the pressing roller 33 is also located above the welding table 2 and can roll along the welding area. The pressing roller 33 and the heating roller 31 are arranged side by side. When the pressing assembly 4 applies pressure to the welding assembly 3, the heating roller 31 and the pressing roller 33 synchronously provide a pressing force to the welding area. When the driving assembly 5 provides a driving force to the welding assembly 3, the heating roller 31 and the pressing roller 33 synchronously roll along the welding area. Along the rolling forward direction of the heating roller 31 during welding, the pressing roller 33 is located behind the heating roller 31, and is used to achieve the pressing and cooling of the welding position passed by the heating roller 31.

[0057] Preferably, the welding assembly 3 further comprises a clamping link 34, which is rollably disposed on the base 1, a clamping roller 33 is disposed at one end of the clamping link 34, and the clamping assembly 4 and the driving assembly 5 both act on the clamping link 34. Specifically, the clamping link 34 is disposed on the upper surface of the front end of the base 1 along the front-to-back direction, the clamping link 34 can roll along the left-to-right direction on the base 1, and the clamping roller 33 is disposed at the front end of the clamping link 34 and is suspended on the front end side of the base 1 and is located above the welding table 2. When welding, the rolling forward direction of the heating roller 31 is from left to right, then the clamping roller 33 is located on the left side of the heating roller 31 and is arranged side by side with the heating roller 31, and the clamping link 34 is also located on the left side of the heating link 32 and is arranged side by side with the heating link 32. When a plurality of heating connecting rods 32 and heating rollers 31 are arranged side by side in the left-right direction, the pressing rollers 33 and pressing connecting rods 34 are located on the left side of the leftmost heating rollers 31 and heating connecting rods 32. When the pressing assembly 4 applies pressure to the welding assembly 3, it acts on the heating connecting rods 32 and pressing connecting rods 34 at the same time, so that the heating rollers 31 and pressing rollers 33 are pressed down with the heating connecting rods 32 and pressing connecting rods 34 and provide pressing force to the welding area. When the driving assembly 5 provides driving force to the welding assembly 3, the heating connecting rods 32 and pressing connecting rods 34 are synchronously rolled on the base 1 in the left-right direction, and the heating rollers 31 and pressing rollers 33 are synchronously rolled along the welding area with the heating connecting rods 32 and pressing connecting rods 34.

[0058] See also Figures 5 to 7 In this embodiment, preferably, the pressing assembly 4 includes a fixing rod 41, a blocking rod 42, a movable buckle 43, a spring 44 and a movable plate 45. Figure 1The fixed rod 41 is fixed on the base 1, the blocking rod 42 is located above the welding assembly 3, and one end of the blocking rod 42, the movable buckle 43 and the movable plate 45 are all rotatably connected to the fixed rod 41. One end of the blocking rod 42, the movable buckle 43 and the movable plate 45 are parallel to the rotation axis of the fixed rod 41. When one end of the blocking rod 42 rotates relative to the fixed rod 41, the other end of the blocking rod 42 moves toward or away from the top of the welding assembly 3. The blocking rod 42 is provided with teeth 421, and one end of the movable buckle 43 is provided with a clamping tooth 431. The two ends of the spring 44 are respectively connected to the fixed rod 41 and the other end of the movable buckle 43. The tension of the spring 44 makes the clamping tooth 431 fit with the teeth 421 to limit the rotation direction of the blocking rod 42 to one-way rotation toward the welding assembly 3. When the latching teeth 431 are engaged with the teeth 421, the latching teeth 431 are stuck between two adjacent teeth 421, so that the position of the blocking rod 42 relative to the fixed rod 41 is fixed, and the blocking rod 42 can be rotated by applying an external force to the blocking rod 42. In addition, the shape of the teeth 421 allows the blocking rod 42 to only rotate toward the direction close to the top of the welding assembly 3 under the action of an external force, and the reverse rotation is blocked by the latching teeth 431 and cannot be rotated in the direction away from the top of the welding assembly 3. One end of the movable plate 45 is arranged opposite to the latching teeth 431. When the end of the movable plate 45 opposite to the latching teeth 431 rotates toward the latching teeth 431, it pushes the latching teeth 431 and enters between the latching teeth 431 and the teeth 421, so that the latching teeth 431 are separated from the teeth 421. When the latching teeth 431 are separated from the teeth 421, the rotation of the blocking rod 42 is no longer restricted. Therefore, before welding, the movable plate 45 is in the initial position. Under the pulling force of the spring 44, the tooth 431 on the movable buckle 43 is engaged with the tooth 421 on the baffle rod 42. The baffle rod 42 can be rotated toward the welding component 3 until the baffle rod 42 is in pressure contact with the welding component 3. After rotating into place, the external force is removed, and the tooth 431 is stuck between the two adjacent teeth 421 to lock the baffle rod 42 in the current position, maintaining pressure on the welding component 3 until the welding is completed. After welding is completed, the movable plate 45 is rotated so that the end of the movable plate 45 opposite to the latch tooth 431 rotates toward the latch tooth 431 and pushes the latch tooth 431 to disengage the tooth 421 to loosen the blocking rod 42, and the blocking rod 42 can be rotated in the direction away from the welding component 3 to separate the blocking rod 42 from the welding component 3 and remove the clamping force on the welding component 3, so that the welded strip can be taken out. After the blocking rod 42 is rotated to a suitable position to separate from the welding component 3, the movable plate 45 is rotated in the opposite direction to reset to the initial position, and the movable buckle 43 will automatically reset to the latch tooth 431 under the tension of the spring 44 until the tooth 421 is engaged with the tooth 421 and the blocking rod 42 is locked in the current position.

[0059] Specifically, the fixing rod 41 is fixed to the right side of the front end of the base 1, the blocking rod 42 is arranged above the heating link 32 and the pressing link 34 of the welding assembly 3 in the left-right direction, the right end of the blocking rod 42 is rotatably connected to the fixing rod 41, and the axis of rotation of the blocking rod 42 relative to the fixing rod 41 extends in the front-to-back direction, so that when the blocking rod 42 rotates, it changes its position between a horizontal state located above the welding assembly 3 in the left-right direction and an inclined or vertical state located on the right side of the welding assembly 3 in the up-down direction. The blocking rod 42 is in pressure contact with the heating link 32 and the pressing link 34 of the welding assembly 3 when it is in a horizontal state or a state close to the horizontal state. When the blocking rod 42 is in a horizontal state, the extension length in the left-right direction covers the rolling travel range of the heating connecting rod 32 and the pressing connecting rod 34, so as to ensure that the blocking rod 42 can keep applying pressure to the heating connecting rod 32 and the pressing connecting rod 34 during the process of the heating roller 31 and the pressing roller 33 rolling through the welding area for welding, so that the heating roller 31 and the pressing roller 33 keep providing a pressing force to the welding area. The middle part of the movable buckle 43 is rotatably connected to the fixed rod 41 through a pin shaft, and the rotation axis of the movable buckle 43 relative to the fixed rod 41 is the axis of the pin shaft, and the axis of the pin shaft extends in the front-to-back direction. The middle part of the movable plate 45 is rotatably connected to the fixed rod 41 through a connecting shaft 46, and the axis of the connecting shaft 46 extends in the front-to-back direction. The right end of the blocking rod 42 is rotatably connected to the connecting shaft 46, so that the rotation axis of the blocking rod 42 relative to the fixed rod 41 coincides with the rotation axis of the movable plate 45 relative to the fixed rod 41, and both are the axes of the connecting shaft 46. An annular boss 420 is formed at the right end of the blocking rod 42, and the annular boss 420 is coaxially arranged with the connecting shaft 46, and a plurality of teeth 421 are formed on the outer peripheral surface of the left side of the annular boss 420. The movable buckle 43 is arc-shaped, and the arc-shaped movable buckle 43 is arranged on the outer peripheral side of the left side of the annular boss 420 and is arranged concentrically with the annular boss 420. A tooth 431 is formed on the side of the lower end of the movable buckle 43 facing the annular boss 420, and the upper end of the movable buckle 43 is connected to one end of the spring 44, and the other end of the spring 44 is connected to the connecting pin 47 on the fixed rod 41, and the connecting pin 47 is located on the side of the movable buckle 43 away from the annular boss 420, so that under the pulling force of the spring 44, the tooth 431 on the movable buckle 43 is engaged with the tooth 421 on the blocking rod 42 to lock the blocking rod 42, and at this time, the blocking rod 42 can only rotate downward, and cannot rotate upward. An arc portion 451 is formed at one end of the movable plate 45, and the arc portion 451 is concentrically arranged with the annular boss 420 and is located on the outer periphery of the annular boss 420. In the initial position, the arc portion 451 is located on the upper side of the plurality of teeth 421, close to the latch teeth 431 on the upper side and arranged opposite to the latch teeth 431. A handle portion 452 extends from the other end of the movable plate 45, and the handle portion 452 extends relative to the fixed rod 41 for the operator to hold to rotate the movable plate 45.When the blocking rod 42 needs to be released, the handle 452 is rotated upward to rotate the movable plate 45 counterclockwise, and the arc portion 451 is rotated downward to push the latching tooth 431 out of the tooth 421. At this time, the blocking rod 42 can rotate freely up and down.

[0060] In this embodiment, preferably, see Figure 1 The base 1 is provided with a stopper 11, which is arranged opposite to the fixing rod 41 at an interval, and the welding assembly 3 is located between the stopper 11 and the fixing rod 41 and can move back and forth between the stopper 11 and the fixing rod 41. The stopper 11 and the fixing rod 41 jointly define the range of motion of the welding assembly 3. When the strip is placed on the welding table 2, the welding area of ​​the strip should be located within the range of motion of the welding assembly 3. Specifically, the stopper 11 is fixed on the left side of the front end of the base 1, and is arranged at an interval with the fixing rod 41 on the base 1 along the left-right direction.

When the strip is placed on the welding platform 2, one side of the strip can be close to the front end surface of the base 1, thereby playing the role of strip alignment and limiting, ensuring the alignment of the strip before and after welding.

[0068] Preferably, the control unit 6 may include a controller, a display screen, a power switch and a temperature control button. The controller may be a PLC controller or a single chip microcomputer. The display screen is used to display the temperature information detected by the first temperature sensor and the second temperature sensor.

Fig.10 The portable strip welding device of this embodiment may also be provided with a power cord 7, which is used to connect a power source to supply power to the device. The portable strip welding device of this embodiment may also be provided without the power cord 7, and instead be provided with a battery of suitable capacity for power supply, so as to be applicable to application scenarios where power supply is inconvenient.

[0069] In order to reduce the overall weight and make it more portable, in the portable strip welding device of this embodiment, the components contacting the welding area are mainly made of materials with good thermal conductivity, light weight, and will not be wetted and attached by solder, such as aluminum.

[0070] The portable strip welding device of this embodiment is particularly suitable for welding superconducting strips. In addition, it can also be used for welding copper strips and copper strips, and copper strips and superconducting strips. Of course, it is also applicable to welding strips of other materials. And the appropriate welding table 2, heating roller 31 and pressing roller 33 can be replaced according to the welding requirements of different strip models, so that strip welding can be achieved in any situation, and the application scenarios are very wide.

[0071] When the portable strip welding device of this embodiment is used, after selecting and assembling the appropriate soldering station 2, heating roller 31 and pressing roller 33 according to the strip to be welded, the strip to be welded is first placed on the soldering station 2, and solder, such as tin sheet or tin wire, is placed in the welding area to be welded on the strip, so that one side of the strip is close to the front end surface of the base 1, and the welding area is within the range of movement of the heating roller 31 and the pressing roller 33. Then the two pressing heads 14 are rotated downward so that the two pressing heads 14 press and fix the two sides of the welding area of ​​the strip on the soldering station 2. Subsequently, the power is turned on, the power switch of the control unit 6 is turned on, and the set welding temperature is input through the temperature control button. The controller controls the first heater and the second heater to start and start heating. At the same time, the power of the first heater and the second heater is adjusted and the temperature of the welding station 2 and the heating roller 31 is monitored according to the temperature information detected by the first temperature sensor and the second temperature sensor. After the temperature of the welding station 2 and the heating roller 31 reaches the set welding temperature, the stopper 42 is manually turned downward to a horizontal state or a near-horizontal state, so that the stopper 42 is in pressure contact with the heating connecting rod 32 and the clamping connecting rod 34 to limit the movement of the heating roller 31 and the clamping roller 33, and at the same time ensure that the heating roller 31 and the clamping roller 33 provide sufficient clamping force to the welding area. Subsequently, the rear end of the handle 52 is manually turned to make the lifting platform 51 descend, and the clamping connecting rod 34 is pushed by the connecting rod 53 to drive the heating connecting rod 32 to roll forward synchronously from left to right, and the clamping roller 33 and the heating roller 31 roll forward synchronously from left to right along the welding area. During the forward movement, the heating roller 31 heats the solder in the welding area, causing the solder to melt and infiltrate the surface of the strip. At the same time, the pressing roller 33 and the heating roller 31 maintain the pressing force on the welding area, so that the welding area is tightly fitted together, and the pressing roller 33 presses and cools the welding position that the heating roller 31 passes after the heating roller 31. The rolling speed of the pressing roller 33 and the heating roller 31, that is, the speed of welding, depends on the temperature during welding, whether the solder is melted, and whether the encapsulation tin on the surface of the strip is melted. The rolling speed of the pressing roller 33 and the heating roller 31 can be controlled by manually rotating the speed of the rear end of the handle 52.When the heating roller 31 passes the welding area, the clamping roller 33 is at the tail of the welding area and the solder is observed to solidify, and the welding is completed. The handle 452 of the movable plate 45 is manually rotated upward to make the movable plate 45 rotate counterclockwise. The arc portion 451 of the movable plate 45 is rotated downward to push the latch tooth 431 out of the tooth 421 and release the baffle rod 42. The pressure applied to the heating link 32 and the clamping link 34 is reduced accordingly, and the clamping force of the clamping roller 33 and the heating roller 31 is also reduced accordingly. The baffle rod 42 is rotated upward to make the baffle rod 42 leave the heating link 32 and the clamping link 34, so as to remove the pressure applied to the heating link 32 and the clamping link 34, thereby removing the clamping force of the clamping roller 33 and the heating roller 31. At this time, the rear end of the handle 52 is slightly rotated in the opposite direction to make the lifting platform 51 rise slightly, and then the two pressing heads 14 are rotated upward to release the welded strip. After the strip is taken out, the rear end of the handle 52 is continuously rotated to raise the lifting platform 51 to reset, driving the connecting rod 53, the clamping connecting rod 34, the clamping roller 33 and the heating roller 31 to roll leftward back to the initial position, and a welding process is completed.

[0072] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
