Description

Technical Field

[0001] The invention relates to the technical field of copper tape quantitative conveying mechanisms, and in particular to a copper tape quantitative conveying mechanism for chip packaging. Background Art

[0002] Chip packaging is the process of assembling integrated circuits into final chip products, that is, placing the integrated circuit die on a substrate that acts as a carrier, bringing out the pins and then fixing and packaging them into a whole as a chip. In the chip packaging process, a variety of metals are usually required. Copper is usually used to manufacture electrical circuits in chips due to its low resistance and good conductivity. At the same time, copper materials can also be used as part of the packaging material, acting as an optimizer to reduce energy loss, thereby achieving better packaging effects. Since the control of precision in chip packaging is extremely strict, the size requirements for the copper tape used in the chip packaging process are also high.

[0003] At present, a Chinese utility model with the announcement number CN216632778U discloses a copper strip fixed-length cutting device, including a driving part, a follower part and a cutting part. The driving part includes a driving gear, a driving friction wheel, a driving shaft and a connecting key. The driving friction wheel has bosses on both sides, and the two sides of the driving friction wheel are connected to a driving gear through the bosses. The driving friction wheel has a lower bayonet, and a lower tool is installed in the lower bayonet. The driving friction wheel is connected to the driving shaft through a connecting key. The driving shaft is also connected to a power source to drive the driving friction wheel to rotate. The follower part includes a follower gear, a follower friction wheel and a follower shaft. The two sides of the follower friction wheel are connected to a follower gear through the bosses. The follower gear and the driving gear are meshed to transmit rotation. The follower friction wheel has an upper bayonet, and an upper tool is installed in the upper bayonet. The follower friction wheel and the follower gear are both installed on the follower shaft. The cutting part includes a lower tool and an upper tool. The lower tool is installed on the driving friction wheel, and the upper tool is installed on the follower friction wheel.

[0004] The existing utility model conveys the copper strip forward by the friction force of the active friction wheel. When the active friction wheel rotates one circle, the lower cutter and the upper cutter respectively rotate one circle with the active friction wheel and the follower friction wheel and finally cut together to complete a copper strip cutting operation. The length of the cut copper strip is the circumference of the active friction wheel. However, on the one hand, due to the good ductility of the copper strip, the copper strip will be stretched along the conveying direction due to the friction force during the conveying process of the copper strip, thereby affecting the accuracy of the copper strip; on the other hand, the existing utility model has poor conveying accuracy when the single conveying length of the copper strip is small, and it is difficult to achieve flexible and accurate adjustment of the single conveying length of the copper strip, which needs to be improved.

[0016] In summary, the present invention has the following beneficial effects:

[0017] 1. The copper belt quantitative conveying component is provided with a length adjustment component, a constant force clamping component and a quantitative pushing component. When the copper belt is conveyed, the constant force clamping component drives the driving worm to rotate through the driving motor, thereby driving the driving turbine and the clamping gear to rotate, and then drives the clamping rack and the clamping block to slide synchronously towards each other, thereby clamping the copper belt. During the synchronous sliding of the clamping block, the pressing abutment block abuts against the front and back sides of the copper belt. With the movement of the clamping block, the compression spring is compressed, thereby exerting elastic force on the copper belt, thereby clamping the copper belt. By controlling the sliding distance of the clamping block and thus controlling the compression amount of the compression spring, the force acting on the surface of the copper belt can be controlled, that is, the clamping force can be controlled by controlling the driving motor, thereby avoiding the pressure acting on the copper belt. If the tension is too large, the copper belt will be compressed and deformed, thus affecting the conveying effect. After the constant-force clamping assembly clamps the copper belt, the tension adjusting assembly is adjusted so that the copper belt is in a relaxed state. At this time, the constant-force clamping assembly is pushed by the quantitative pushing assembly so that the copper belt between the guide seat and the pressing abutment block is pushed into the second guide assembly, thereby completing the quantitative conveying of the copper belt. Since the copper belt is in a relaxed state before being pushed, the tensile force acting on the copper belt will not cause the copper belt to extend in the conveying direction during the quantitative conveying process, thereby affecting the precision of the quantitative conveying of the copper belt. Since the copper belt is in a taut state during the clamping process of the copper belt, the copper belt between the guide seat and the pressing abutment block can be ensured to be in a taut state, thereby ensuring the precision of the quantitative conveying of the copper belt.

[0018] 2. The length of the copper belt for quantitative delivery can be adjusted by adjusting the distance between the guide seat and the clamping abutment block by adjusting the length adjustment component. The adjustment of the single delivery length of the copper belt is more flexible and accurate. In addition, since the length adjustment component uses a screw rod for adjustment, the adjustment accuracy is higher, and it can adapt to the adjustment and delivery requirements when the single delivery length of the copper belt is small, and the structure is simple.

DETAILED DESCRIPTION

[0025] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0026] Example:

[0027] refer to Figures 1 to 5 A copper tape quantitative conveying mechanism for chip packaging comprises a base 1 arranged along a vertical direction, on which a copper tape unloading component 2, a first guide component 3, a copper tape quantitative conveying component 4, a second guide component 5 and a copper tape cutting component 6 are respectively arranged along the conveying direction of the copper tape. The copper tape is output from the copper tape unloading component 2 and sequentially passes through the first guide component 3 for preliminary positioning, and then passes through the copper tape quantitative output component to achieve quantitative output of the copper tape. The output copper tape passes through the second guide component 5 for further guidance and ensures that the copper tape is always output in a horizontal direction. Finally, the output copper tape passes through the copper tape cutting component 6 to achieve cutting of the quantitatively output copper tape, and several first guide components are provided. A tension adjustment component 7 for adjusting the tightness of the copper belt during the conveying process is provided between the guide components 3. The tension adjustment component 7 is used to ensure that the copper belt is in a taut state before the copper belt is clamped, thereby ensuring the accuracy of the output length of the copper belt. During the copper belt conveying process, the copper belt is in a relaxed state, thereby avoiding the tension acting on the copper belt, which causes the copper belt to be stretched and extended, thereby affecting the accuracy of the copper belt. The copper belt quantitative conveying component 4 includes a length adjustment component 41 fixedly connected to the base 1, and a constant force clamping component 42 movably arranged on the length adjustment component 41, which is used to clamp the copper belt, and a quantitative pushing component 43 that pushes the constant force clamping component 42 to push the copper belt a certain distance. In this embodiment, the quantitative pushing component 43 uses a telescopic electric cylinder so that the length of the constant force clamping component 42 can be adjusted while the length adjustment component 41 adjusts the single output length of the copper belt.

[0028] refer to Figure 1 Specifically, the length adjustment component 41 includes a length adjustment seat 411 fixedly connected to the base 1 and a length adjustment screw rod 412 connected to the length adjustment seat 411 in a horizontal direction. A mounting seat 413 for mounting the constant force clamping assembly 42 and the quantitative pushing assembly 43 and an adjusting motor 414 for driving the length adjustment screw rod 412 to rotate are slidably connected to the length adjustment seat 411 in a horizontal direction. When it is necessary to adjust the single output length of the copper strip, the length adjustment screw rod 412 is driven to rotate by the adjusting motor 414, thereby driving the mounting seat 413 and the constant force clamping assembly 42 and the quantitative pushing assembly 43 fixed on the mounting seat 413 to move, thereby realizing accurate and flexible adjustment of the single conveying length of the copper strip.

[0029] refer to Figure 3 to Figure 4Specifically, the constant force clamping assembly 42 includes a clamping seat 421 slidably connected to the mounting seat 413 along the horizontal direction and a clamping block 422 symmetrically slidably connected to the clamping seat 421 along the vertical direction. A clamping rack 423 is fixedly connected to the end of the clamping block 422 away from the second guide assembly 5 along the vertical direction. A clamping gear 424 meshing with the clamping rack 423 is symmetrically rotatably connected to the clamping seat 421. A driving turbine 425 is coaxially fixedly connected to the clamping gear 424. A driving worm 426 is rotatably connected between the clamping block 422 and a driving motor 427 is fixedly connected to drive the driving worm 426 to rotate. A sliding rod 428 is slidably connected to the clamping block 422 along the vertical direction. The end of the sliding rod 428 away from the clamping block 422 is fixedly connected to a horizontally arranged clamping abutment block 429. A compression spring 4210 is sleeved and connected to the sliding rod 428. The end of the clamping abutment block 429 away from the sliding rod 428 is fixedly connected to a friction pad for increasing the friction between the clamping abutment block 429 and the copper belt. 4211, a distance sensor 4212 for measuring the distance between the pressing abutment block 429 and the second guide assembly 5 is fixedly provided at one end of the pressing abutment block 429 close to the clamping block 422. The distance sensor 4212 can assist the length adjustment assembly 41 in accurately adjusting the length of the single output of the copper belt to improve the output accuracy. When the copper belt is conveyed, the constant force clamping assembly 42 drives the driving worm 426 to rotate through the driving motor 427, thereby driving the driving turbine 425 and the clamping gear 424 to rotate, and then drives the clamping rack and the clamping gear 424 to rotate. The blocks 422 slide synchronously towards each other to achieve the clamping of the copper belt. During the synchronous sliding of the clamping blocks 422, the pressing and abutting blocks 429 abut against the front and back sides of the copper belt. As the clamping blocks 422 move, the compression springs 4210 are compressed to exert elastic force on the copper belt to achieve the clamping of the copper belt. The force acting on the surface of the copper belt can be controlled by controlling the sliding distance of the clamping blocks 422 and thus the compression amount of the compression springs 4210, thereby avoiding compression and deformation of the copper belt due to excessive pressure on the copper belt, which affects the conveying effect.

[0030] refer to Figure 1 and Figure 5 Specifically, the second guide assembly 5 includes a guide seat 51 fixedly connected to the base 1 and a guide hole 52 opened in the guide seat 51 along the horizontal direction. A positioning groove 53 for positioning the copper belt is opened at the bottom of the guide hole 52 to ensure that the copper belt can always be output along the direction of the positioning groove 53. A plurality of second guide wheels 54 are connected to the top of the guide hole 52 and rotate evenly in parallel along the conveying direction of the copper belt to avoid warping of the copper belt during the output process and affect the conveying accuracy of the copper belt. The end face of the guide seat 51 close to the constant force clamping assembly 42 is parallel to the end face of the clamping abutment block 429, and the interval between the two end faces is equal to the length of the copper belt conveyed in a single time.

[0031] refer to Figure 1 Specifically, the copper strip unloading assembly 2 includes a copper strip unloading roller 21 rotatably connected to a seat and a servo unloading motor 22 fixedly connected to the base 1 for driving the copper strip unloading roller 21 to rotate. The servo unloading motor 22 drives the copper strip unloading roller 21 to rotate, thereby further assisting the tension adjustment assembly 7 to adjust the tension of the copper strip.

[0032] refer to Figure 1 to Figure 2 Specifically, the first guide assembly 3 is symmetrically rotatably connected to the first guide wheel 31 of the base 1, and a guide groove 32 equal to the width of the copper belt is coaxially opened on the first guide wheel 31. The copper belt is transported along the direction of the guide groove 32 during transportation to avoid deviation in the transportation direction. The tension adjustment assembly 7 includes a tension adjustment electric cylinder 71 fixedly connected to the base 1 and an abutment wheel 72 fixedly connected to the telescopic end of the tension adjustment electric cylinder 71 for abutting the copper belt. A pressure sensor 73 is fixedly provided between the tension adjustment electric cylinder 71 and the abutment wheel 72. When the copper belt needs to be in a tightened state, the tension adjustment cylinder 71 drives the abutment wheel 72 to abut the copper belt. At this time, the pressure reading of the pressure sensor 73 is greater than 0, thereby realizing that the copper belt is in a tightened state. Conversely, when the pressure reading of the pressure sensor 73 is 0, it indicates that the copper belt is in a relaxed state.

[0033] refer to Figure 1 and Figure 5 Specifically, the copper strip cutting assembly 6 includes a cutting cylinder 61 fixedly connected to the base 1 along the vertical direction and a cutting knife 62 fixedly connected to the telescopic end of the cutting cylinder 61. The cutting knife 62 is arranged to fit the end surface of the guide seat 51 away from the constant force clamping assembly 42. When the copper strip is output from the guide seat 51, the cutting cylinder 61 drives the cutting knife 62 to descend to achieve the cutting of the copper strip. The cutting knife 62 is arranged to fit the end surface of the guide seat 51 away from the constant force clamping assembly 42 to avoid bending during the copper strip cutting process and affecting the accuracy of the copper strip.

[0034] Brief description of the use process: the copper strip is output from the copper strip unloading component 2 and passes through the first guide component 3 for preliminary positioning, and then passes through the copper strip quantitative output component to achieve the quantitative output of the copper strip. The output copper strip passes through the second guide component 5 for further guidance and ensures that the copper strip is always output in the horizontal direction. Finally, the output copper strip passes through the copper strip cutting component 6 to achieve the cutting of the quantitative output copper strip. When the copper strip is conveyed, the constant force clamping component 42 drives the driving worm 426 to rotate through the driving motor 427, thereby driving the driving turbine 425 and the clamping gear 424 to rotate, and then drives the clamping rack and the clamping block 422 to slide synchronously to achieve the clamping of the copper strip. During the synchronous sliding process of the clamping block 422, the abutment block 42 is pressed. 9 abuts against the front and back sides of the copper strip. As the clamping block 422 moves, the compression spring 4210 is compressed to apply elastic force on the copper strip to achieve clamping of the copper strip. The force acting on the surface of the copper strip can be controlled by controlling the sliding distance of the clamping block 422 and thus controlling the compression amount of the compression spring 4210, thereby avoiding compression and deformation of the copper strip due to excessive pressure on the copper strip, which affects the conveying effect. After the constant force clamping assembly 42 clamps the copper strip, the tension adjustment assembly 7 is adjusted to make the copper strip in a relaxed state. At this time, the constant force clamping assembly 42 is pushed by the quantitative pushing assembly 43, so that the copper strip located between the guide seat 51 and the clamping abutment block 429 is pushed into the second guide assembly 5, thereby completing the quantitative conveying of the copper strip.

After reading this specification, those skilled in the art can make creative modifications to this embodiment as needed, but as long as it is within the scope of the claims of the present invention, it will be protected by the patent law.
