Description

Ultrasonic welding machine with horn level adjustment function}

The present invention relates to an ultrasonic welder with a horn horizontality adjustment function, and more specifically, an ultrasonic welder with a horn horizontality adjustment function that allows the horizontality of the horn, which is distorted during the joining process when replacing the horn, to quickly match the horizontality of the anvil. It's about a welder.

As the demand for secondary batteries as an energy source increases, lithium secondary batteries, which exhibit high energy density and operating potential, long cycle life, and low self-discharge rate, are being widely used in electronic products.

In particular, lithium secondary batteries are actively applied to electric vehicles (EV) and hybrid electric vehicles (HEV), which are used to replace fossil fuels such as gasoline and diesel, which are one of the main environmental causes of air pollution.

These lithium secondary batteries mainly use lithium-based oxide and carbon materials as positive and negative electrode active materials, respectively, and are cells that aggregate unit cells with a structure in which positive and negative plates coated with these active materials are arranged with a separator in between. It is provided with an assembly and a pouch case that seals and stores the cell assembly together with the electrolyte.

Depending on the shape of the pouch case, lithium secondary batteries are classified into can-type secondary batteries in which the cell assembly is built into a metal can, and pouch-type secondary batteries in which the cell assembly is built in a pouch case of an aluminum laminate sheet.

Here, the pouch-type secondary battery has a structure in which a cell assembly to which plate-shaped electrode leads are connected is sealed with an electrolyte in a pouch case.

Additionally, a portion of the electrode lead is exposed to the outside of the pouch case, and the exposed electrode lead is electrically connected to a device on which the secondary battery is mounted or is used to electrically connect the secondary batteries to each other.

Figure 1 is an exploded perspective view showing the configuration of a conventional pouch-type lithium secondary battery.

The conventional pouch-type lithium secondary battery 10 includes an electrode assembly 11, a plurality of electrode tabs 12 and 13 extending from the electrode assembly 11, and welding and joining the electrode tabs 12 and 13. It is comprised of a pouch case 16 that accommodates electrode leads 14 and 15 and an electrode assembly 11.

Here, the electrode tabs 12 and 13 extend from each electrode plate of the electrode assembly 11, and the electrode leads 14 and 15 are electrically connected to each other by welding with the electrode tabs 12 and 13 extending from each electrode plate. It is connected to and is coupled in a form that is partially exposed to the outside of the pouch case (16).

The pouch case 16 is made of a soft packaging material such as an aluminum laminate sheet, has a space for accommodating the electrode assembly 11, and has an overall pouch shape.

In addition, when welding the electrode tabs 12, 13 and the electrode leads 14, 15, resistance welding, laser welding, etc. may cause excessive energy to be applied to the electrode assembly 11, deteriorating the performance of the lithium secondary battery. Therefore, eco-friendly ultrasonic welding is mainly used these days.

Here, a typical ultrasonic welder includes an ultrasonic power supply, an ultrasonic transducer, a booster, a horn, and anvil.

The ultrasonic oscillator converts 60 Hz AC current into a high frequency current of 20 kHz or more and supplies it to the ultrasonic oscillator.

Ultrasonic oscillators convert electrical energy into mechanical energy and are also called ultrasonic piezoelectrics.

That is, the high-frequency current generated by the ultrasonic oscillator is converted into ultrasonic waves by the ultrasonic oscillator, and the converted ultrasonic waves move to the booster, which amplifies the received ultrasonic waves and transmits them to the horn.

The horn pressurizes the surface of the electrode tab and electrode lead placed on the upper surface of the anvil with a certain load and simultaneously applies amplified ultrasonic waves received from the booster to weld it.

Figure 2 is a diagram showing a welding state using a general ultrasonic welder.

As shown in FIG. 2, the electrode tabs 12 and 13 connected to the electrode assembly and the electrode leads 14 and 15 are placed on the anvil 20 in an overlapping contact state, and are horned on the surface corresponding to the anvil 20. (30) Ultrasonic welding is performed while applying pressure.

While the horn 30 applies pressure in the vertical direction, it vibrates in the horizontal direction to generate frictional heat at the contact surface between the electrode tabs 12 and 13 and the electrode leads 14 and 15, and the frictional heat generated in this way causes the electrode tab to (12, 13) and electrode leads (14, 15) are welded to each other. Here, while the horn 30 moves up and down to apply pressure in the vertical direction, the anvil 20 is generally fixed.

Here, the biggest requirement that determines the quality of ultrasonic welding is the horizontality of the horn and anvil.

Figure 3 is a diagram showing welding quality according to the horizontality of the horn and anvil in ultrasonic welding.

As shown in FIG. 3, if the anvil 20 and the horn 30 are parallel as shown on the left side of the drawing, the welding quality is good, but if the horn is horizontal as shown on the right side of the drawing, the welding quality becomes poor.

Therefore, in order to ensure uniformity of welding quality, the horizontality of the newly replaced horn and anvil must match as the anvil and horn wear out.

However, although setting the anvil's level is easy, setting the horn's level is very cumbersome.

Figure 4 is a diagram showing an example of a horn installed in an ultrasonic welder and a housing.

In a conventional ultrasonic welder, the anvil 20 is structured to be seated and fixed at a specific position on the main body, so there is no difficulty in setting the horizontality.

However, in the case of the horn 30, when the worker assembles the booster into the booster and fixes it to the housing, since the booster is cylindrical, the worker visually checks the level and secures the housing with bolts. At this time, in the process of fixing the housing, micro-distortion of the horn occurs periodically, so there is a problem that the worker takes a long time to work by adjusting the level of the horn by repeatedly loosening and tightening the bolt.

Moreover, it is difficult to determine the degree of distortion numerically, so there is a problem that welding with a test welding sample and then setting it while observing its shape.

The horn 130 pressurizes the surface of the welding object (electrode tab, electrode lead, pouch, etc.) seated on the knurled surface 170a of the anvil 170 with a certain load and simultaneously applies amplified ultrasonic waves received from the booster to perform welding. By ultrasonic welding an object, the object is coupled to the tip of the ultrasonic welding head 120 so that it can be placed directly above the anvil 170, as shown in FIGS. 5 and 6.

At the right end of the horn 130 in the drawing, a male screw 130a is formed so that it can be spirally coupled to the ultrasonic welding head 120, as shown in FIG. 8, and the female screw 130a is fastened to the ultrasonic welding head 120. (120a) is formed.

In addition, as shown in FIG. 8, protruding knurling protrusions 131 that contact the knurled surface 170a of the anvil 170 are formed on the upper and lower surfaces of the horn 130, and on the rear side of the knurled protrusions 131 A flat portion 132 having a flat surface is formed.

Here, since the driving method of the horn 130 is a common matter, description will be omitted.

The rotating body 140 allows the ultrasonic welding head 120, which has penetrated the housing 110, to be rotatably placed inside the housing 110. As shown in FIGS. 8 and 9, the ultrasonic welding head 120 It is arranged between the upper housing 111 and the lower housing 112, covering a portion of the appropriate location in the longitudinal direction.

At this time, the rotating body 140 is open on both sides so that the ultrasonic welding head 120 can penetrate inside, and the outer shape may have a circular or polygonal shape.

The rotating body 140 as described above rotates the ultrasonic welding head 120 through rotation while supporting the ultrasonic welding head 120, which ultimately causes the horn 130 to be fastened to the tip through the rotation of the ultrasonic welding head 120. ) so that the horizontality can be set.

In addition, so that the rotating body 140 can be rotatably installed in the housing 110, bearings 142 are provided on both sides of the outer peripheral surface of the rotating body 140, and these bearings 142 are located in the housing as shown in FIG. 9. (110) It is installed inside.

Meanwhile, as shown in FIGS. 7 to 9, the outer peripheral surface of the rotating body 140 extends vertically inside the upper housing 111 so that the rotating body 140 can be rotated to the left or right, and has a horizontal shape described later. A tilting piece 141 having a predetermined length that is tilted (rotated) in the left or right direction may be formed by the angle adjustment member 161 and the position setting member 162 of the walking control means 160 (FIGS. 11A to 11A) 11c).

The detection sensor 150 detects the horizontality of the horn 130 coupled to the tip of the ultrasonic welding head 120, and is arranged in a pair at the lower part of the horn 130 as shown in FIGS. 5 to 7. do.

At this time, the pair of detection sensors 150 are preferably arranged to be spaced apart from each other within the width range of the flat portion 132 having a flat surface of the horn 130.

That is, the pair of detection sensors 150 detect both sides of the flat part 132 when the horizontality is shifted to one side while the horn 130 is fastened to the ultrasonic welding head 120 as shown in FIG. 7. This is to be able to calculate the slope value of the horn 130.

The tilt value of the horn 130 calculated through the detection sensor 150 is received by a control unit (not shown) and can be checked through the display screen, and the operator operates the horizontality correction means 160, which will be described later, while checking the display from time to time. This sets the horizontality of the horn 130.

In addition, the detection sensor 150 detects in real time whether the horizontality of the horn 130 is distorted during welding work on the horn 130 after setting the horizontality of the horn 130, thereby preventing welding defects in advance.

In addition, the detection sensor 150 is preferably a laser sensor that can measure the distance on both sides of the flat part 132 through laser irradiation, but the type is not limited as long as it is a sensor that detects the distance.

The horizontality correction means 160 corrects the horizontality of the horn 130 and rotates the rotating body 140 to the left or right according to the horizontality state of the horn 130 obtained through the detection sensor 150. The horizontality of the distorted horn 130 is set to match the horizontality of the anvil 170 placed on the lower side.

In other words, the horizontality of the horn 130 is set so that the detection values of the left and right sides of the flat part 132 of the horn 130 through the detection sensor 150 are “0”.

For this purpose, as shown in FIGS. 5 to 9, the horizontality correction means 160 penetrates both sides of the housing 110 and contacts one side and the other side of the tilting piece 141, respectively, on one side as shown in the drawing. An angle adjustment member 161 is provided to control the angle of the tilting piece 141 through left and right forward and backward movement, and the other side is in contact with the tilting piece 141 tilted by the angle adjustment member 161. A position setting member 162 that maintains the tilting angle of the tilting piece 141, a tilting piece 141 disposed inside the housing 110 and in contact with the other side of the tilting piece 141, and tilted by the angle adjustment member. ) may be composed of an elastic support member 163 that elastically supports the other side.

The angle adjustment member 161 and the position setting member 162 maintain a predetermined length so that they can penetrate the housing 110 and come into contact with the tilting piece 141, and each tip is in contact with the tilting piece 141. By achieving this state, the tilted angle of the tilting piece 141 is maintained.

Here, the angle adjustment member 161 is disposed through the left side of the housing 110 in the drawing, and the position setting member 162 is shown as disposed through the right side in the drawing, but the positions are not necessarily limited. .

In other words, the functions of the angle adjustment member 161 and the position setting member 162 can be changed depending on their positions. For example, when the angle adjustment member 161 advances to the right in the drawing, the position setting member 162 ) corresponds to this, retreating to the right in the drawing as much as the angle adjustment member 161 has moved.

In addition, the position setting member 162 supports the other side of the tilting piece 141 tilted by the angle adjustment member 161, so that the horn 130 is moved by vibration that continuously occurs during the continuous welding process of the horn 130. ) is prevented from becoming horizontally distorted.

As shown in the drawings, the elastic support member 163 is disposed on the right side of the tilting piece 141 in the open inner space of the housing 110 to elastically support the tilting piece 141 and at the same time adjust the angle at all times. It is pushing in the direction of member 161.

At this time, the elastic support member 163 is preferably a compression spring so as to constantly support the tilting piece 141, and the type of the elastic support member 163 that elastically supports the tilting piece 141 is not limited. No.

In addition, the angle adjustment member 161 and the position setting member 162 penetrate into the housing 110 through a spiral combination to enable precise advancement and retreat by the operator, and advance and retreat to the left and right in the drawing according to the direction of the spiral coupling. do.

In addition, the outer peripheral surfaces of the angle adjustment member 161 and the position setting member 162 move along the threads and come into close contact with the outer surface of the housing 110, thereby following the advance and retreat of the angle adjustment member 161 and the position setting member 162. A stopper (S) may be provided to ensure that the position is fixed.

Meanwhile, Figure 10 shows another embodiment of the angle adjustment member 161' and the position setting member 162' among the main components of the ultrasonic welder 100.

As shown in FIG. 10, the angle adjustment member 161' and the position setting member 162' are drive motors disposed on one side and the other side of the housing 110 while penetrating both sides of the housing 110, respectively. It is connected to (164), and the tilting piece 141 can be tilted by moving forward and backward to the left and right in the drawing by driving the drive motor 164.

That is, the above embodiment is suitable for an automated process in a workplace where a worker cannot be present by allowing the angle adjustment member 161' and the position setting member 162' to advance and retreat by the drive motor 164.

At this time, the drive motor 164 is preferably a servo motor so that the precise advance and retreat of the angle adjustment member 161' and the position setting member 162' can be automatically implemented. The type of the driving motor 164 is not limited as long as it can accurately implement the advance and retreat of the member 162'.

Hereinafter, the process of setting the horizontality of the horn 130 using the ultrasonic welder 100 according to the present invention will be described with reference to the attached drawings.

Prior to explanation, the angle adjustment member 161 and the position setting member 162 will be explained as an example of a screw connection method.

First, in order to replace the horn 130 or change the direction of the knurling protrusion 131, the male screw 130a of the horn 130 is screwed and coupled to the female screw 120a at the tip of the ultrasonic welding head 120.

At this time, since the horizontality of the combined horn 130 cannot be completely horizontal, it is always deviated by a predetermined angle θ in one direction, as shown in FIG. 11A.

Meanwhile, the anvil 170 is fixed to the support block and its horizontality is already set.

When the combination of the horn 130 is completed, a pair of detection sensors 150 simultaneously sense both sides of the flat part 132 of the horn 130 as shown in a dashed line, and the sensed inclination value of the horn 130 is sent to the control unit. It is transmitted to and displayed on the display screen.

In Figure 11a, for example, the horn 130 is shown as being turned to the left in the drawing.

When the horn 130 is twisted as above, the operator retracts the position setting member 162 to the right in the drawing as shown in FIG. 11b, and also retracts the stopper (S).

At this time, since the tilting piece 141 of the rotating body 140 is supported by the elastic support member 163 as shown in FIG. 6, tilting in one direction is achieved even if the position setting member 162 is spaced apart by retreating. It is not lost.

Thereafter, the operator checks the inclination value of the horn 130 displayed on the display screen and moves the angle adjustment member 161 forward to the right in the drawing as shown in FIG. 11b, while tilting the tilting piece 141 in the direction of the arrow. At this time, the stopper (S) of the angle adjustment member 161 is also spaced apart from the housing 110.

Here, the advance of the angle adjustment member 161 proceeds until the inclination value of each sensor 150 that detects the horizontality of the horn 130 becomes “0”.

And, the elastic support member 163 is in a state of providing continuous elasticity in the direction of the angle adjustment member 161.

Afterwards, when the horizontality setting of the horn 130 is completed, the receding position setting member 162 is advanced until it contacts the right side of the tilting piece 141 in the drawing as shown in FIG. 11c, and the stopper (S) is The horizontality of the horn 130 is fixed by preventing the position setting member 162 from loosening by adhering closely to the housing 110.

As a result, the horizontality of the horn 130 matches the horizontality of the anvil 170, which has already been set to horizontality.

And, when the horizontality setting of the horn 130 is completed through the above setting process, the central axis of the rotating body 140 is tilted at a predetermined angle as shown in Figure 11c.

As described so far, the ultrasonic welder with the horn horizontality adjustment function of the present invention does not repeatedly perform housing assembly and disassembly and horn horizontal adjustment as in the past when the horizontality is distorted during horn replacement or welding work. There is an excellent effect of quickly setting the horizontality of the horn by rotating the horn while the horn is fixed to the housing.

In addition, the technical effect of preventing welding defects in advance is excellent by setting the horizontality of the combined horn through a detection sensor and having the detection sensor detect the occurrence of horn distortion during welding work.

Above, the ultrasonic welder with the horn leveling function of the present invention has been described with reference to preferred embodiments and the attached drawings, but this is only intended to aid understanding of the invention and is not intended to limit the technical scope of the invention thereto. am.

In other words, various changes and modifications can be made by those skilled in the art without departing from the technical gist of the present invention, and such changes and modifications are within the technical scope of the present invention in terms of interpretation of the claims. It goes without saying that it is within.
