Description

Technical Field

[0001] This invention relates to the field of bonding aluminum strip cutting technology, specifically to a high-efficiency aluminum strip cutting device. Background Technology

[0002] In semiconductor packaging, a large number of aluminum strips of specific sizes are used. When cutting bonding aluminum strips, existing cutting devices have two main drawbacks: firstly, they do not provide good fixation for the bonding aluminum strips; secondly, when cutting vertically with a cutter, the cut is prone to deformation or breakage. In the invention patent with publication number CN119566399A, a stepping cutting device for bonding aluminum strips is disclosed, which includes an operating table, a curve cutting component, and an auxiliary fixing component. As the cutting progresses, the middle fixing component can move with the cutter to prevent the end cutting component from stretching and deforming the bonding aluminum strip, thus ensuring efficient cutting of the bonding aluminum strip.

[0003] While this device possesses the aforementioned advantages, it still suffers from the following drawbacks in practical use: 1) The device has a relatively complex fixing method and structure for bonding aluminum strips, which results in low actual processing efficiency. 2) The device clamps the ends of the bonding aluminum strip using two end fixing rollers, but the outer arc surface of the end fixing rollers cannot completely clamp the two sides of the cut, which makes deformation problems still easy to occur during cutting.

[0009] A further technical improvement of the present invention is that a tension wheel is connected to the outer surface of the transmission belt, and the shaft end of the tension wheel is rotatably connected to the outer surface of the crossbar.

[0011] A further technical improvement of the present invention is that an unloading unit is provided on the outside of the transmission wheel. The unloading unit includes a rotating plate. The outer surface of the rotating plate is embedded and movably connected to the outer surface of the crossbar. One side of the outer surface of the rotating plate is hinged to the outer surface of the crossbar. A push-pull rod is rotatably connected to the outer surface of the rotating plate.

[0014] Beneficial effects This invention provides a high-efficiency aluminum strip cutting device. Compared with the prior art, it has the following advantages: (1) By setting up a cutting device, the bonding aluminum strip can be completely wrapped by the material trough. On the one hand, it is convenient for the drive motor and the roller to convey the bonding aluminum strip through the groove. On the other hand, the laser cutter cuts the bonding aluminum strip through the laser beam and the cutting groove, avoiding the problem of deformation and breakage at the cutting point. At the same time, the lead screw drives the slider to slide, so that the laser cutter moves and the output end of the reset rod is stretched by the traction rope. When the bonding aluminum strip moves to the bottom of the laser cutter, the laser cutter is driven to slide back and reset by the rebound of the output end of the reset rod. Thus, the bonding aluminum strip can be automatically cut, thereby improving the cutting efficiency. Thus, the conveying and cutting of the bonding aluminum strip are carried out sequentially and are related.

[0015] (2) By setting up a linkage component, the drive wheel, the transmission belt and the transmission wheel are connected to drive the bonding aluminum strip to slide, so that the laser cutter moves synchronously and stretches the reset rod when the rotating roller drives the bonding aluminum strip to slide. This allows the bonding aluminum strip to be conveyed and cut sequentially. At the same time, the output end of the adjusting rod drives the arc strip to move by extension and retraction, thereby adjusting the transmission ratio between the drive wheel and the transmission wheel. This allows the bonding aluminum strip to be cut to different lengths without changing the movement path of the laser cutter, thereby improving the applicability of the device.

[0016] (3) By setting up an unloading unit, the rotating plate is kept parallel to the crossbar by the action of the support plate, push-pull rod and hinge, so that the cut bonding aluminum strip can be supported by the baffle. At the same time, by rotating the rotating plate and sliding the baffle into the groove, the groove can place the cut bonding aluminum strip. After the rotating plate rotates, the cut bonding aluminum strip can be slidably guided and its movement can be prevented from deviating, so that the cut bonding aluminum strip can be accurately unloaded, thereby improving the convenience, applicability and processing efficiency of the device.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

The outer surface of the horizontal bar 6 is respectively provided with a material groove 7 and an abutment groove 8. The internal dimensions of the material groove 7 are adapted to the external dimensions of the bonding aluminum strip to completely enclose it and prevent deformation at the cut point, while also improving the stability of conveying and clamping. The inner width and length of the abutment groove 8 are smaller than those of the material groove 7 to maintain the stability of the bonding aluminum strip sliding inside the material groove 7. Preferably, ball bearings or rollers can be embedded inside the material groove 7 to reduce sliding wear of the bonding aluminum strip through rolling action. The interiors of the material groove 7 and the abutment groove 8 are connected. The material groove 7 is used for... The aluminum strip is conveyed via a sliding mechanism. A cutting groove 9 is located directly below the laser cutter 5. The width of the cutting groove 9 is matched to the outer diameter of the laser beam emitted by the laser cutter 5, while its inner length is greater than or equal to the inner width of the material trough 7 to ensure complete cutting of the bonded aluminum strip. Preferably, the body of the crossbar 6, located around the cutting groove 9, is equipped with liquid cooling (not shown in the figure) to prevent deformation at the cut due to high temperatures during laser cutting. The cutting groove 9 is formed on the outer surface of the crossbar 6 and communicates with the interior of the material trough 7. A drive motor 10 is fixedly connected to the outer surface of the crossbar 6. The drive motor 10 is electrically connected to an external control circuit, and its output is connected via a coupling. A rotating roller 11 is fixedly connected. The rotating roller 11 is made of a rubber material with good mold groove performance. It drives the bonded aluminum strip to slide through friction with the bonded aluminum strip, which can realize the continuous conveying of the bonded aluminum strip and facilitate the interference fit between the two and avoid the problem of wear. The outer surface of the rotating roller 11 is rotatably connected to the inside of the material trough 7 and the abutment trough 8 respectively. A reset rod 12 is fixedly connected to the outer surface of the frame 1.

The transmission wheel is divided into arc strips 35 at equal angles. An adjusting rod 36 is fixedly connected to the arc surface of the arc strips 35. The adjusting rod 36 is made of an electric push rod and is electrically connected to an external control circuit. As a preferred method, the lead screw 2 is provided with a sliding contact element to facilitate the electrical connection of the adjusting rod 36. One end of the adjusting rod 36 is fixedly connected to the outer arc surface of the ratchet 33. A transmission belt 37 is driven to the outer surface of the transmission wheel. The transmission belt 37 is made of an existing synchronous belt. A drive wheel 38 is driven to the outer surface of the transmission belt 37. The specific value of the transmission ratio between the drive wheel 38 and the transmission wheel is adaptively adjusted according to the cutting length of the bonded aluminum strip. The outer surface of the drive wheel 38 is fixedly connected to the shaft end of the rotating roller 11.

[0023] The outer surface of the transmission belt 37 is connected to a tension wheel 39. The tension wheel 39 stretches the transmission belt 37 so that when the arc bar 35 moves, the angle between the transmission belt 37 and the arc bar 35 is maintained, so that the roller 11 can stably drive the lead screw 2 to rotate. The shaft end of the tension wheel 39 is embedded in the outer surface of the cross bar 6 for rotational connection.

[0024] An adjusting wheel 310 is connected to the outer surface of the transmission belt 37. The reciprocating sliding of the adjusting wheel 310 facilitates the movement of the adjusting rod 36 and the arc strip 35 to achieve adaptive adjustment of the transmission belt 37. A rotating frame 311 is rotatably connected to the outer surface of the adjusting wheel 310. A telescopic rod 31 is fixedly connected to the outer surface of the rotating frame 311. The telescopic rod 31 is made of a spring rod. Through its own elastic force, the transmission belt 37 is kept in a stretched and taut state when the arc strip 35 moves, thereby avoiding the problem of the transmission belt 37 disengaging. One end of the telescopic rod 31 is fixedly connected to the outer surface of the crossbar 6.

[0025] An unloading unit 34 is provided outside the transmission wheel. The unloading unit 34 includes a rotating plate 341. The surface of the rotating plate 341 and the inner wall of the material trough 7 are at the same height on the side supporting the bonded aluminum strip. A receiving measure for the bonded aluminum strip (not shown in the figure) is provided below the rotating end of the rotating plate 341. The receiving measure includes, but is not limited to, a conveyor belt or a receiving box. The outer surface of the rotating plate 341 is embedded and movably connected to the outer surface of the crossbar 6. One side of the outer surface of the rotating plate 341 is hinged to the outer surface of the crossbar 6. A push-pull rod 342 is rotatably connected to the outer surface of the rotating plate 341. The push-pull rod 342 is made of electric push rod and is electrically connected to an external control circuit. The extension and retraction of the output end controls the rotating plate 341 to rotate around the hinge axis to facilitate the unloading of the bonded aluminum strip after cutting. A support plate 343 is rotatably connected to one end of the push-pull rod 342. The outer surface of the support plate 343 is fixedly connected to the outer surface of the crossbar 6.

[0026] The outer surface of the rotating plate 341 has a groove 344, the inner width of which matches the inner width of the material trough 7, to facilitate wrapping the cut bonding aluminum strip and thus enabling precise feeding. The interior of the groove 344 is connected to the interior of the material trough 7. A baffle 345 is slidably connected inside the groove 344. The outer dimensions of the baffle 345 match the inner dimensions of the groove 344, and its surface is at the same height as the surface of the rotating plate 341 to support the cut bonding aluminum strip. A slide rail 346 is fixedly connected inside the groove 344, and two slide rails are slidably connected to the outer surface of the slide rail 346. Linear motor 347 is electrically connected to an external control circuit and has a self-locking function to improve the stability of baffle 345.

[0027] Both sides of the outer surface of the fixed wedge 349 are provided with slots 3410, and the inside of the slots 3410 on both sides is movably connected with a strip 3411. The cross-section of the strip 3411 is T-shaped to improve the stability of the connection between the fixed wedge 349 and the sliding wedge 348. The length of the strip 3411 is less than the inner length of the slot 3410 to facilitate the oblique abutment between the fixed wedge 349 and the sliding wedge 348. The outer surfaces of the strips 3411 on both sides are fixedly connected to the outer surfaces of the sliding wedges 348 on both sides.

[0028] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0029] Working principle: When cutting the bonded aluminum strip, one end of the bonded aluminum strip to be cut is inserted into the material groove 7 through one end of the crossbar 6. As it is continuously pushed in, the bonded aluminum strip is connected to the rotating roller 11 with an interference fit. Then, according to the cutting length of the bonded aluminum strip, the output end of the adjusting rod 36 is extended or retracted to adjust the relative position of the arc strip 35, thereby adjusting the transmission ratio between the transmission wheel and the drive wheel 38. During the adjustment process, the adjusting wheel 310 and the tensioning wheel 39 keep the transmission belt 37 in a taut state to prevent the transmission belt 37 from disengaging and affecting the linkage between the rotating roller 11 and the lead screw 2. At the same time, during the movement of the arc strip 35, the adjusting wheel 310 synchronously stretches or compresses the output end of the telescopic rod 31 through the rotating frame 311, thereby enabling motion compensation between the arc strip 35 and the adjusting wheel 310. Next, the drive motor 10 drives the rotating roller 11 to rotate inside the groove 8. Through the contact friction between the rotating roller 11 and the bonded aluminum strip, the bonded aluminum strip slides inside the material trough 7. When the rotating roller 11 rotates, it drives the drive wheel 38 at one end to rotate synchronously. Through the transmission connection between the drive wheel 38, the transmission belt 37 and the transmission wheel, and through the action of the ratchet pawl of the ratchet 33, the lead screw 2 rotates synchronously. Thus, through the threaded connection between the lead screw 2 and the slider 4, the slider 4 is made to fit against the fixed frame 1 to slide along the axial direction of the lead screw 2. During the movement of the slider 4, the output end of the reset rod 12 is stretched by the action of the traction rope 13 and the fixed pulley 15. When the cutting point of the bonded aluminum strip moves to the laser cutting... When the laser cutter is directly below the cutting groove 9, the cutting is aligned vertically. At this time, the drive motor 10 stops driving the rotating roller 11 to rotate, the lead screw 2 synchronously disengages from the rotational driving force, and the output end of the reset rod 12 also disengages from the external tension. The output end of the reset rod 12 then slowly and transportively retracts, thereby pulling the slider 4 to slide back and reset through the action of the traction rope 13. At this time, the laser cutter 5 emits a laser beam, which irradiates the cutting area of ​​the bonded aluminum strip through the cutting groove 9, thereby realizing the laser cutting processing of the bonded aluminum strip. During the cutting process, the liquid cooling cooling measures on the body of the crossbar 6 dissipate heat and cool the cutting area of ​​the bonded aluminum strip to avoid deformation of the cutting area due to high temperature. The cut bonding aluminum strip is supported by the baffle 345 on the rotating plate 341. Then, the linear motors 347 on both sides slide away from each other along the slide rail 346, causing the fixed wedges 349 to disengage from the sliding wedges 348. This allows the baffle 345 to slide down inside the groove 344, allowing the cut bonding aluminum strip to slide into the groove 344 and be wrapped by it. During the movement of the fixed wedges 349 and the sliding wedges 348, the locking strip 3411 slides synchronously inside the locking groove 3410 to maintain the stability of the connection. Then, the push-pull rod 342 outputs... The plate retracts to pull one end of the rotating plate 341 to rotate around the hinge axis, causing one end of the rotating plate 341 to rotate downwards. During this process, the cut bonding aluminum strip slides down under its own gravity and is guided by the anti-deviation function of the groove 344, thus being fed onto the receiving device below. Subsequently, the output end of the push-pull rod 342 extends, causing the rotating plate 341 to rotate in the opposite direction and reset. At the same time, the linear motors 347 on both sides slide in the opposite direction to reset the baffle 345 so that the bonding aluminum strip can be supported again. Then, the above steps are repeated to continuously cut the bonding aluminum strip.

[0030] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
