Description

Technical Field

[0001] This invention relates to the field of chip manufacturing technology, and in particular to a copper sheet punching and transfer device in chip manufacturing. Background Technology

[0002] A chip, also known as an integrated circuit, microcircuit, microchip, or wafer / chip, is a miniaturized circuit used in electronics and is often manufactured on the surface of a semiconductor wafer. In chip manufacturing, the packaging process requires placing and soldering copper sheets of specific shapes onto the corresponding chip to form a qualified soldered product before injection molding. Therefore, the copper sheets need to be pre-cut to the required shape and specifications. During the copper sheet cutting process, the copper sheet is placed in a mold, and then cut using a combination of upper and lower blades to obtain a copper sheet of a specific shape at a designated location. Existing copper sheet cutting processes often suffer from unreasonable design and insufficient processing technology, resulting in poor cutting of the copper sheets. The cut copper sheets are difficult to remove from the mold, easily causing damage during removal, affecting the processing quality, and are inefficient, hindering actual production.

[0015] The beneficial effects of this invention are:

[0016] 1. When copper sheets need to be punched into a certain shape, the copper sheet is first placed on the punching table, so that the copper sheet is at the upper end of the lower punching module. At this time, the inner rod of the first telescopic cylinder retracts, driving the upper top seat to move downward. The upper top seat drives the rotary transmission mechanism and the limit seat to move downward. The limit seat drives the punching mechanism and the negative pressure adsorption mechanism to move downward. The suction cup in the negative pressure adsorption mechanism first contacts the copper sheet. When the suction cup is squeezed against the copper sheet, the suction cup undergoes a certain deformation. At this time, the first telescopic cylinder stops retracting, causing the upper punching blade in the punching mechanism to move downward. The upper punching blade and the lower punching module work together to punch the copper sheet. When the punching mechanism moves downward, a negative pressure is formed in the suction cup of the negative pressure adsorption mechanism, which then firmly adsorbs the punched copper sheet, fixing the punched copper sheet for easy subsequent transfer.

[0017] 2. The inner rod of the first telescopic cylinder extends upward, causing the upper top seat to move upward. The upper top seat causes the rotary transmission mechanism and the limiting seat to move upward. The limiting seat causes the punching mechanism and the negative pressure adsorption mechanism to move upward. The suction cup in the negative pressure adsorption mechanism causes the punched copper sheet to move upward. When the positioning rod in the punching mechanism is completely removed from the positioning hole, the motor shaft of the stepper motor drives the cylinder to rotate 180 degrees clockwise. The cylinder drives the support plate to rotate 180 degrees clockwise. The support plate drives the two limiting seats to rotate 180 degrees, causing the two limiting seats to exchange positions. The limiting seats drive the punching mechanism and the negative pressure adsorption mechanism to rotate 180 degrees. The suction cup in the negative pressure adsorption mechanism causes the punched copper sheet to rotate from the punching table to the conveyor belt, thereby transferring the copper sheet. At this time, the second telescopic cylinder resets, causing the inner rod of the second telescopic cylinder to retract the lifting frame, causing the suction cup to release its adsorption on the punched copper sheet, causing the punched copper sheet to fall downward onto the conveyor belt, thereby transferring and conveying it.

[0018] 3. After the operation is completed, simply rotate the cylinder 180 degrees using the stepper motor shaft. The cylinder then rotates the support plate 180 degrees, which in turn causes the two limit seats to exchange positions. The limit seats then rotate the punching mechanism and the negative pressure adsorption mechanism 180 degrees. This process repeats itself. During operation, the stepper motor shaft rotates 180 degrees clockwise, pauses for a period, and then rotates 180 degrees counterclockwise. This alternating motion enables cyclic production with high efficiency. The positioning rod and positioning hole work together to ensure that the upper punching blade and lower punching module can accurately punch the copper sheet, improving the punching quality and efficiency. After punching, the copper sheet is adsorbed by the suction cup in the negative pressure adsorption mechanism. Then, through the combination of the rotary transmission mechanism, the punching mechanism, and the negative pressure adsorption mechanism, the punched copper sheet can be transferred from the punching table to the conveyor belt, preventing damage to the punched copper sheet.

[0028] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The technical solutions in the embodiments of the present invention will be clearly and completely described. 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.

[0029] Please see Figures 1 to 7This invention provides a technical solution: a copper sheet punching and transfer device for chip manufacturing, comprising a punching table 1, a fixed base 11, a conveyor belt 12, and a lower punching module 13. The punching table 1 and the conveyor belt 12 are distributed on both sides of the fixed base 11. The upper end of the punching table 1 is provided with an installation groove, and the lower punching module 13 is fixedly connected to the installation groove at equal intervals. A first telescopic hydraulic cylinder 2 is symmetrically installed on the upper end of the fixed base 11, and the upper end of the first telescopic hydraulic cylinder 2 is fixedly connected to an upper top seat 21. The upper end of the upper top seat 21 is symmetrically provided with limit grooves. 22. A rotary transmission mechanism is installed on the upper end of the upper top seat 21. Limit seats 4 are symmetrically installed on both ends of the rotary transmission mechanism. Through slots 41 are symmetrically opened on the upper end of the limit seats 4. An L-shaped support plate 42 is fixedly connected to the upper end of the limit seats 4. A punching mechanism and a negative pressure adsorption mechanism for copper sheets are installed on the limit seats 4. The upper top seat 21 is moved up and down by the extension and retraction of the first telescopic cylinder 2. The upper top seat 21 drives the limit seats 4 to move up and down through the rotary transmission mechanism. The limit seats 4 drive the punching mechanism and the negative pressure adsorption mechanism to move up and down.

[0030] The rotary transmission mechanism includes a support plate 3 located at the upper end of the upper top seat 21, a cylinder 31 located at the lower end of the support plate 3, and two limiting sliders 32 symmetrically located at the lower end of the support plate 3. The support plate 3 is fixedly connected to the cylinder 31, and the cylinder 31 is rotatably connected to the upper top seat 21. The lower end of the cylinder 31 is fixedly connected to the motor shaft of the stepper motor. The limiting sliders 32 are fixedly connected to the support plate 3. The two ends of the support plate 3 are respectively fixedly connected to the two limiting seats 4. The stepper motor is installed at the lower end of the upper top seat 21 by bolts. The motor shaft of the stepper motor drives the cylinder 31 to rotate 180 degrees clockwise or counterclockwise. The cylinder 31 drives the support plate 3 to rotate 180 degrees clockwise or counterclockwise. During operation, the motor shaft of the stepper motor first rotates 180 degrees clockwise, then pauses for a period of time, and then rotates 180 degrees counterclockwise. This alternating motion occurs. The two limiting seats 4 are symmetrically distributed at both ends of the support plate 3.

[0031] The lower end of the supporting horizontal plate 3 is in contact with the upper end of the upper top seat 21. The limiting slider 32 is slidably connected with the limiting groove 22. The cross-sections of the limiting slider 32 and the limiting groove 22 are both convex. When the supporting horizontal plate 3 rotates along the upper end of the upper top seat 21, the supporting horizontal plate 3 drives the limiting slider 32 to rotate along the limiting groove 22, thereby enabling the supporting horizontal plate 3 to rotate stably.

[0032] The punching mechanism includes two second telescopic cylinders 5 symmetrically arranged on the upper end of the limiting seat 4, a lifting frame 51 arranged on the lower end of the second telescopic cylinders 5, two transmission gear plates 52 symmetrically arranged on both sides of the lifting frame 51, a positioning base plate 53 arranged on the lower end of the lifting frame 51, and multiple upper punching blades 54 and four positioning rods 55 arranged on the lower end of the positioning base plate 53. The second telescopic cylinders 5 are fixedly connected to the limiting seat 4, and the lower end of the second telescopic cylinders 5 are fixedly connected to the lifting frame 51. The positioning base plate 53 is respectively connected to the lifting frame 51 and the lower end of the lifting frame 51. The frame 51, the upper punch cutter 54 and the positioning rod 55 are fixedly connected. The upper end of the punching table 1 is symmetrically provided with positioning holes 14. The positioning rod 55 is set directly above the positioning hole 14. Multiple upper punch cutters 54 are symmetrically distributed in pairs at the lower end of the positioning base plate 53. The upper punch cutter 54 and the positioning base plate 53 are detachably connected. When the punching mechanism moves downward, the positioning rod 55 slides down along the positioning hole 14, so that the upper punch cutter 54 and the lower punching module 13 in the punching mechanism can accurately punch the copper sheet.

[0033] A controller is installed on the side of the punching table 1. The controller is connected to the first telescopic cylinder 2, the stepper motor and the second telescopic cylinder 5 respectively.

[0034] The upper end of the limiting seat 4 is provided with a support groove running from top to bottom. The through groove 41 is connected to the support groove, the lifting frame 51 is slidably connected to the support groove, and the transmission gear plate 52 is slidably connected to the through groove 41.

[0035] The negative pressure adsorption mechanism includes an air cylinder body 6 mounted on an L-shaped support plate 42, an air cylinder cover seat 61 mounted on the upper end of the air cylinder body 6, a movable plug rod 62 and a movable plug 63 mounted inside the air cylinder body 6, two bent main air pipes 64 symmetrically mounted on the lower end of the air cylinder body 6, two branch air pipes 65 symmetrically mounted on the bent main air pipes 64, two branch air pipes 66 mounted on the lower end of the branch air pipes 65, a suction cup 67 mounted on the lower end of the branch air pipes 66, a positioning sleeve 68 mounted on the branch air pipes 66, and a transmission assembly mounted on the movable plug rod 62.

[0036] The transmission assembly includes a concave lifting plate 7 disposed on the upper end of the movable piston rod 62, two drive gear plates 71 symmetrically disposed on the inner side of the concave lifting plate 7, and gears 72 disposed on the side of the drive gear plates 71. When the concave lifting plate 7 drives the movable piston rod 62 to move upward, the movable piston rod 62 drives the movable plug 63 to move upward along the inner cavity of the air cylinder body 6, thereby drawing the gas from the bent main air pipe 64, branch air pipe 65, branch air pipe 66 and suction cup 67 into the air cylinder body 6. This creates a negative pressure inside the suction cup 67, which then firmly adheres to the punched copper sheet. When the concave lifting plate 7 moves the movable stopper rod 62 downward, the movable stopper rod 62 moves the movable stopper 63 downward along the inner cavity of the air cylinder 6. This allows gas from the air cylinder 6 to flow into the bent main air pipe 64, branch air pipe 65, branch air pipe 66, and suction cup 67, causing the suction cup 67 to separate from the punched copper sheet, thus releasing its grip on the sheet. The negative pressure adsorption mechanism enables the adsorption of the punched copper sheet. Through the coordinated operation of the rotary transmission mechanism, punching mechanism, and negative pressure adsorption mechanism, the punched copper sheet can be transferred from the punching table 1 to the conveyor belt 12, thereby achieving the transfer and transport of the copper sheet.

[0037] The cylinder body 6 is installed from top to bottom through the upper end of the L-shaped support plate 42, and the cylinder body 6 is fixedly connected to the L-shaped support plate 42. The cylinder body 6 is threadedly connected to the cylinder cover seat 61. The movable stopper rod 62 is slidably connected to the cylinder cover seat 61. The lower end of the movable stopper rod 62 is fixedly connected to the movable stopper 63. The movable stopper 63 is slidably connected to the inner cavity of the cylinder body 6.

[0038] The upper end of the bent main air pipe 64 is fixedly connected to the lower end of the air cylinder body 6. The bent main air pipe 64 is connected to the branch air pipe 65 through a pipe joint. The branch air pipe 65 is connected to the branch air pipe 66 through a pipe joint. The lower end of the branch air pipe 66 is fixedly connected to the suction cup 67. The lower end of the positioning sleeve 68 is fixedly connected to the suction cup 67. The upper end of the positioning sleeve 68 is fixedly connected to the lower end of the limiting seat 4. The upper end of the bent main air pipe 64 is connected to the inner cavity of the air cylinder body 6. The lower end of the branch air pipe 66 passes through the limiting seat 4, the lifting frame 51, the positioning base plate 53 and the upper punch cutter 54 in sequence. The lower end of the branch air pipe 66 is connected to the suction cup 67. The lower end of the positioning sleeve 68 passes through the positioning base plate 53 and the upper punch cutter 54 in sequence. The suction cup 67 is fixed by the positioning sleeve 68.

[0039] The lower end of the concave lifting plate 7 is slidably connected to the through groove 41, and the gear 72 is rotatably connected to the through groove 41. The gear 72 meshes with the transmission gear plate 52 and the drive gear plate 71 respectively. The transmission gear plate 52 and the drive gear plate 71 are distributed on both sides of the gear 72. The transmission gear plate 52 and the drive gear plate 71 move in opposite directions. When the transmission gear plate 52 moves up and down, it drives the gear 72 to rotate. The gear 72 drives the drive gear plate 71 to move up and down.

[0040] Working principle: When copper sheets need to be punched into a certain shape, the copper sheet is first placed on the punching table, so that the copper sheet is at the upper end of the lower punching module 13. At this time, the inner rod of the first telescopic cylinder 2 retracts, driving the upper top seat 21 to move downward. The upper top seat 21 drives the rotary transmission mechanism and the limiting seat 4 to move downward. The limiting seat 4 drives the punching mechanism and the negative pressure adsorption mechanism to move downward. The suction cup 67 in the negative pressure adsorption mechanism first contacts the copper sheet. When the suction cup 67 is squeezed against the copper sheet, the suction cup 67 undergoes a certain deformation. At this time, the first telescopic cylinder 2 stops retracting, causing the inner rod of the second telescopic cylinder 5 to extend downward. The inner rod of the second telescopic cylinder 5 drives the lifting frame 51 to move downward along the support groove of the limiting seat 4. The lifting frame 51 drives the transmission gear plate 5 2. The positioning base plate 53 moves downward, driving the upper punch cutter 54 and the positioning rod 55 to move downward. At this time, the positioning rod 55 slides downward along the positioning hole 14, so that the positioning base plate 53 can stably drive the upper punch cutter 54 to move downward. The upper punch cutter 54 and the lower punch cutting module 13 cooperate to punch the copper sheet. When the transmission gear plate 52 moves downward, it drives the gear 72 to rotate. The gear 72 drives the drive gear plate 71 to move upward. The drive gear plate 71 drives the concave lifting plate 7 to move upward along the through groove 41. The concave lifting plate 7 drives the movable plug rod 62 to move upward. The movable plug rod 62 drives the movable plug 63 to move upward along the inner cavity of the air cylinder body 6, thereby bending the main air pipe 64, the branch air pipe 65, the branch air pipe 66, and the... The gas inside the suction cup 67 is drawn into the cylinder body 6, creating a negative pressure inside the suction cup 67. This negative pressure then firmly holds the punched copper sheet in place. After the copper sheet is punched, the inner rod of the first telescopic cylinder 2 extends upward, causing the upper top seat 21 to move upward. The upper top seat 21 then moves the rotary transmission mechanism and the limiting seat 4 upward. The limiting seat 4 moves the punching mechanism and the negative pressure adsorption mechanism upward. The suction cup 67 in the negative pressure adsorption mechanism moves the punched copper sheet upward. When the positioning rod 55 in the punching mechanism is completely removed from the positioning hole 14, the motor shaft of the stepper motor drives the cylinder 31 to rotate 180 degrees clockwise. The cylinder 31 then drives the supporting horizontal plate 3 to rotate 180 degrees clockwise. The supporting horizontal plate 3 then rotates the positions of the two limiting seats 4 180 degrees. The two limiting seats 4 are rotated 10 degrees, causing them to exchange positions. The limiting seats 4 drive the punching mechanism and the negative pressure adsorption mechanism to rotate 180 degrees. The suction cup 67 in the negative pressure adsorption mechanism drives the punched copper sheet to rotate from the punching table 1 to the conveyor belt 12, thereby transferring the copper sheet. At this time, the second telescopic cylinder 5 is reset, and the inner rod of the second telescopic cylinder 5 drives the lifting frame 51 to retract. The lifting frame 51 drives the transmission gear plate 52 to move upward. When the transmission gear plate 52 moves upward, it drives the gear 72 to rotate. The gear 72 drives the drive gear plate 71 to move downward. The drive gear plate 71 drives the concave lifting plate 7 to move downward along the through groove 41. The concave lifting plate 7 drives the movable plug rod 62 to move downward. The movable plug rod 62 drives the movable plug 63 to move downward along the inner cavity of the air cylinder body 6.The gas inside the cylinder 6 is then introduced into the bent main air pipe 64, branch pipe 65, branch pipe 66, and suction cup 67, causing the suction cup 67 to separate from the punched copper sheet. This releases the suction cup 67 from the punched copper sheet, allowing it to fall onto the conveyor belt 12 for transport. The punching mechanism and negative pressure suction mechanism on the two limit seats 4 can operate simultaneously, enabling the punching of the copper sheet while simultaneously unloading the previously punched copper sheet. After the operation is complete, the stepper motor shaft drives the cylinder 31 to rotate 180 degrees, which in turn drives the support plate 3 to rotate 180 degrees. The support plate 3 then drives the two limit seats 4 to rotate 180 degrees, exchanging their positions. The base 4 drives the punching mechanism and the negative pressure adsorption mechanism to rotate 180 degrees, repeating this motion. During operation, the stepper motor shaft first rotates 180 degrees clockwise, then pauses for a period of time, and then rotates 180 degrees counterclockwise, alternating in this manner to achieve cyclical production and high work efficiency. Through the cooperation of the positioning rod 55 and the positioning hole 14, the upper punching blade 54 and the lower punching module 13 can accurately punch the copper sheet, improving the punching quality and efficiency. After punching, the copper sheet is adsorbed by the suction cup 67 in the negative pressure adsorption mechanism. Then, through the cooperation of the rotary transmission mechanism, the punching mechanism, and the negative pressure adsorption mechanism, the punched copper sheet can be transferred from the punching table 1 to the conveyor belt 12, preventing damage to the punched copper sheet.
