Description

Technical Field

[0001] The present invention relates to the technical field of devices or apparatuses for controlling the intensity, color, phase, polarization or direction of light, and in particular to an alignable IC prepress machine and an operating method. Background Art

[0002] IC pre-pressing machine is a device for pre-pressing and welding the carrier board and IC chip of the display screen. The carrier board needs to be placed in the mold cavity of the press machine, and then the IC chip is placed in the corresponding position. Pay attention to whether the direction and position of the chip are correct, apply the brush solder paste and solder wire auxiliary materials to the appropriate position, and then move the pressure head downward. The speed and depth of the pressure head descent are also adjusted according to the requirements of the pre-pressing process. After the pressure head is completely dropped, the raw material is attached to the surface of the IC chip, and then the brush solder paste and welding balls are further melted by the temperature of the pressure head to form the required shape. When the pre-pressing time is reached, the pressure head begins to lift. After the pressure head is completely lifted, the motor drives the mold to move horizontally as a whole. Therefore, the pressure head of the IC pre-pressing machine pre-presses and welds the IC chip again. This is a technical inspiration for the IC pre-pressing machine. Research on IC pre-pressing machines found the following problems: The IC pre-pressing machine pre-presses the carrier board and IC chip of the display screen through the pressing head. Since the IC pre-pressing machine needs to pre-press the carrier board and IC chip in an assembly line, the carrier board and IC chip need to move horizontally for pre-pressing. When the pressing head of the IC pre-pressing machine moves downward for pre-pressing, deviations are likely to occur between the pressing head, the carrier board and the IC chip, resulting in the inability to quickly align the pressing head of the IC pre-pressing machine with the carrier board and the IC chip for pre-pressing. At present, CN201910933110.6 in the prior art discloses a COF / FPC / IC high-precision pre-pressing integrated machine. The COF / FPC / IC pre-pressing integrated machine adopts COF / FPC / IC automatic feeding, and performs CCD secondary alignment before pre-pressing. The program control effectively shortens the waiting time and improves the work efficiency; the pre-pressing and the main pressing are integrated into one machine, and the pressing and alignment platform uses a marble platform and a linear motor instead of a lead screw guide pair to move in the X direction, a linear module to move in the Y direction, a DD motor to rotate in the Q direction, and a motor lead screw guide pair to lift and position in the Z direction, which improves the accuracy of COF / FPC / IC hot pressing while reducing the occupied space; The present invention can mainly solve the problem that the pressing head of an IC pre-pressing machine cannot be quickly aligned with a carrier plate and an IC chip for pre-pressing.

[0017] As a further solution of the present invention: the operation method comprises the following steps. The specific operation steps are as follows: S1: Place the carrier and chip inside the cavity of the mold. The motor drives the belt to rotate through the output end. The belt drives the sliding table to move horizontally as a whole through the transmission shaft. Then the control panel controls the motor to stop running. At this time, the cavity at the upper end of the mold is vertically corresponding to the pressure head, and the electric push rod drives the pressure head to move downward; S2: The pressure head moves downward, and the pressure head can pre-press the carrier plate and the chip inside the mold cavity. At this time, the outer wall of the pressure head is squeezed to one side of the extension frame, and the extension frame drives the inclined plate to swing downward through the rotating bearing; S3: When the extension frame tilts downward, the extension frame uses inertia to slide downward at one end of the inclined plate. At this time, the extension frame can limit the two sides of the pressure head. Therefore, when the pressure head slides downward to the inside of the cavity of the mold, the downward sliding inertia of the extension frame can be used to assist the pressure head to align with the inside of the cavity of the mold; S4: When the extension frame slides downward, the cross bar at one end of the extension frame slides synchronously.

At this time, the swing arm can support one side of the cross bar, and then the swing arm can support one side of the extension frame; S5: After the pressure head is pre-pressed, it moves upward, and when the pressure head moves upward, it drives one side of the extension frame to tilt upward and return to its original position. At the same time, the weight of the heavy object is greater than the overall weight of the extension frame and the inclined plate. At this time, the heavy object can swing downward by its own weight; S6: After the extension frame slides upward, the extension frame drives the cross bar to slide toward the inside of the inclined plate, the distance between the cross bar and the hinge is shortened, and the swing arms are tilted and swung synchronously through the hinge, and the distance between the swing arms is increased; S7: The overall temperature of the pressure head is increased by the electric heating wire, and then the pressure head is pre-pressed, and the carrier board and the chip are welded and fixed by melted tin wire. After welding is completed, the motor rotates again, and then the above steps are repeated to form a cycle. Beneficial Effects

[0018] 1. The ram moves downward, and the ram can pre-press the carrier plate and chip inside the mold cavity. At this time, the outer wall of the ram is squeezed to one side of the extension frame, and the extension frame drives the inclined plate to swing downward through the rotating bearing. When the extension frame tilts downward, the extension frame uses inertia to slide downward at one end of the inclined plate. At this time, the extension frame can form a limit on both sides of the ram. Therefore, when the ram slides downward to the inside of the mold cavity, the downward sliding inertia of the extension frame can be used to assist the ram to align with the inside of the mold cavity, so as to avoid deviation between the ram and the carrier plate and chip inside the mold cavity when the ram is pre-pressed downward to the inside of the mold cavity due to the overall mobility of the mold; 2. After the pre-pressing is completed, the pressure head moves upward, and when the pressure head moves upward, it drives one side of the extension frame to tilt upward and return to its original position. At the same time, the weight of the heavy object is greater than the overall weight of the extension frame and the inclined plate. At this time, the heavy object can swing downward by its own weight, so that the extension frame and the inclined plate can be used in a circular manner as a whole without manual adjustment; 3. When the extension frame slides downward, the cross bar at one end of the extension frame slides synchronously. At this time, the distance between the cross bar and the hinge increases, so the swing arm can swing toward one side of the cross bar through the hinge. At this time, the swing arm can support one side of the cross bar, and then the swing arm can support one side of the extension frame, avoiding the extension frame from retracting into the inclined plate due to the reverse extrusion of the pressure head; 4. After the extension frame slides upward, the extension frame drives the cross bar to slide toward the inside of the inclined plate, the distance between the cross bar and the hinge is shortened, and the swing arms are tilted and swung synchronously through the hinge. At this time, the distance between the swing arms is increased, which facilitates the extension frame to quickly return to the inside of the inclined plate. BRIEF DESCRIPTION OF THE DRAWINGS

A speed regulating switch is provided on one side of the motor 103 to adjust the speed of the motor 103, so that the motor 103 can drive the sliding table 201 to move horizontally. The mold 2 has a cavity at the upper end thereof, the cavity is vertically corresponding to the pressing head 102, and the mold 2 slides horizontally through the sliding table 201; Among them: the carrier and the chip are placed inside the cavity of the mold 2, the motor 103 drives the belt 104 to rotate through the output end, the belt 104 drives the sliding table 201 to move horizontally as a whole through the transmission shaft 105, and then the control panel controls the motor 103 to stop running. At this time, the cavity at the upper end of the mold 2 is vertically corresponding to the pressure head 102, and the electric push rod drives the pressure head 102 to move downward. The overall temperature of the pressure head 102 is increased by the electric heating wire, and then the carrier and the chip are welded and fixed by the melted tin wire through the pre-pressing of the pressure head 102. After the welding is completed, the motor 103 rotates again, and then the above steps are repeated to form a cycle. Example 2: Refer to the attached manual Figure 2-6 It can be known that the difference between Example 2 and Example 1 is that mounting frames 3 are installed on both sides of the upper end of the cavity of the mold 2, and a rotating bearing 301 is rotatably connected between the mounting frames 3, and a weight 302 is swingably connected to the lower end of the rotating bearing 301, and an inclined plate 4 and an extension frame 401 are swingably connected to the upper end of the rotating bearing 301, and the extension frame 401 and the inclined plate 4 are slidably nested and connected; Wherein: the mounting frame 3 and the rotating bearing 301, the mounting frames 3 are grouped into two, and the rotating bearing 301 is used in conjunction with each group of the mounting frames 3; A weight 302, which is a weight of 300-400g, and the weight of the weight 302 is greater than the overall weight of the extension frame 401 and the inclined plate 4; The weight of the weight 302 is greater than the overall weight of the extension frame 401 and the inclined plate 4. When the extension frame 401 swings downward as a whole, the weight 302 swings upward through the rotating bearing 301. At this time, the weight 302 can swing downward by its own weight. The inclined plate 4, the inclined plate 4 and the extension frame 401 are all inclined at 15-45 degrees, the extension frame 401 and the inclined plate 4 are both inclined toward one end of the cavity of the mold 2, and the inclined plate 4 is in a linkage relationship with the weight 302 through the rotating bearing 301; The extension frame 401 is in a horizontal "7" shape as a whole. When the pressing head 102 is embedded in the cavity of the mold 2, the outer wall of the pressing head 102 is pressed to one side of the extension frame 401; Among them: the pressing head 102 moves downward, and the pressing head 102 can pre-press the carrier plate and the chip inside the cavity of the mold 2. At this time, the outer wall of the pressing head 102 is squeezed to one side of the extension frame 401, and the extension frame 401 drives the inclined plate 4 to swing downward through the rotating bearing 301. When the extension frame 401 tilts downward, the extension frame 401 uses inertia to slide downward at one end of the inclined plate 4. At this time, the extension frame 401 can form a limit on both sides of the pressing head 102. Therefore, when the pressing head 102 slides downward to the inside of the cavity of the mold 2, the downward sliding inertia of the extension frame 401 can be used to assist the pressing head 102 to align with the inside of the cavity of the mold 2, so as to avoid the deviation between the pressing head 102 and the carrier plate and the chip inside the cavity of the mold 2 when the pressing head 102 is pre-pressed downward to the inside of the cavity of the mold 2 due to the overall mobility of the mold 2; After the pre-pressing is completed, the pressure head 102 moves upward, and when the pressure head 102 moves upward, it drives one side of the extension frame 401 to tilt upward and return to its original position. At the same time, the weight 302 is greater than the overall weight of the extension frame 401 and the inclined plate 4. At this time, the weight 302 can swing downward by its own weight, so that the extension frame 401 and the inclined plate 4 can be used in a circular manner as a whole without manual adjustment; Example 3: Refer to the attached manual Figure 4-8It can be seen that the difference between Example 3 and Example 1-2 is that a cross bar 402 is passed through the end of the extension frame 401 close to the inclined plate 4, a hinge 501 is hinged inside the inclined plate 4, both sides of the hinge 501 are swingably connected with swing arms 5, and a slider 502 is provided at the end of the swing arm 5 away from the hinge 501, and rubber rings 503 are inlaid at both ends of the slider 502; Among them: the cross bar 402, the cross bar 402 is used in conjunction with the extension frame 401, a slide groove is opened on one side of the cross bar 402, and the slider 502 slides on both sides of the slide groove. The cross bar 402 and the extension frame 401 are combined into a "T" shape; The crossbar 402 and the extension frame 401 are combined into a "T" shape, which can prevent the extension frame 401 from falling off the side of the inclined plate 4 when the extension frame 401 slides downward on the side of the inclined plate 4; Hinge 501 and swing arm 5, the swing arm 5 is hinged on both sides of the hinge 501, the swing arm 5 swings in opposite directions on both sides of the hinge 501, the swing arm 5 and the slider 502 are matched, and the swing arm 5 swings obliquely on one side of the cross bar 402 through the slider 502; The rubber ring 503 is inclined at 5-25 degrees, and one end of the rubber ring 503 that is inclined upward is located on a side of the slider 502 close to the crossbar 402; The rubber ring 503 is inclined at 5-25 degrees, and the upwardly inclined end of the rubber ring 503 is located on the side of the slider 502 close to the cross bar 402. The setting of the rubber ring 503 can prevent the slider 502 from falling off on one side of the cross bar 402 during the sliding process; When the extension frame 401 slides downward, the cross bar 402 at one end of the extension frame 401 slides synchronously. At this time, the distance between the cross bar 402 and the hinge 501 increases, so the swing arm 5 can swing toward one side of the cross bar 402 through the hinge 501. At this time, the swing arm 5 can support one side of the cross bar 402, and then the swing arm 5 can support one side of the extension frame 401, so as to avoid the extension frame 401 from retracting into the inclined plate 4 due to the reverse extrusion of the pressure head 102; After the extension frame 401 slides upward, the extension frame 401 drives the cross bar 402 to slide toward the inside of the inclined plate 4, the distance between the cross bar 402 and the hinge 501 is shortened, and the swing arms 5 are synchronously tilted and swung through the hinge 501. At this time, the distance between the swing arms 5 is increased, which facilitates the extension frame 401 to quickly return to the inside of the inclined plate 4; Example

[0029] The operation method includes the following steps: S1: Place the carrier and the chip inside the cavity of the mold 2. The motor 103 drives the belt 104 to rotate through the output end. The belt 104 drives the sliding table 201 to move horizontally as a whole through the transmission shaft 105. Then the control panel controls the motor 103 to stop running. At this time, the cavity at the upper end of the mold 2 is vertically corresponding to the pressure head 102, and the electric push rod drives the pressure head 102 to move downward; S2: The pressing head 102 moves downward, and the pressing head 102 can pre-press the carrier plate and the chip inside the cavity of the mold 2. At this time, the outer wall of the pressing head 102 is pressed to one side of the extension frame 401, and the extension frame 401 drives the inclined plate 4 to swing downward through the rotating bearing 301; S3: When the extension frame 401 tilts downward, the extension frame 401 slides downward at one end of the inclined plate 4 by inertia. At this time, the extension frame 401 can limit the two sides of the pressing head 102. Therefore, when the pressing head 102 slides downward to the inside of the cavity of the mold 2, the downward sliding inertia of the extension frame 401 can be used to assist the pressing head 102 to align with the inside of the cavity of the mold 2. S4: When the extension frame 401 slides downward, the cross bar 402 at one end of the extension frame 401 slides synchronously, and the distance between the cross bar 402 and the hinge 501 increases. Therefore, the swing arm 5 can swing obliquely toward one side of the cross bar 402 through the hinge 501. At this time, the swing arm 5 can support one side of the cross bar 402, and then the swing arm 5 can support one side of the extension frame 401; S5: After the pre-pressing is completed, the pressure head 102 moves upward, and when the pressure head 102 moves upward, it drives one side of the extension frame 401 to tilt upward and return to its original position. At the same time, the weight 302 is greater than the overall weight of the extension frame 401 and the inclined plate 4, and the weight 302 can swing downward by its own weight; S6: After the extension frame 401 slides upward, the extension frame 401 drives the cross bar 402 to slide toward the inside of the inclined plate 4, the distance between the cross bar 402 and the hinge 501 is shortened, and the swing arms 5 are tilted and swung synchronously through the hinge 501, and the distance between the swing arms 5 is increased; S7: The overall temperature of the pressing head 102 is increased by the electric heating wire, and then the pressing head 102 is pre-pressed, and the carrier plate and the chip are welded and fixed by the melted tin wire. After the welding is completed, the motor 103 rotates again, and then the above steps are repeated to form a cycle.

At this time, the outer wall of the pressing head (102) is pressed to one side of the extension frame (401), and the extension frame (401) drives the inclined plate (4) to swing downward through the rotating bearing (301); S3: When the extension frame (401) tilts downward, the extension frame (401) uses inertia to slide downward at one end of the inclined plate (4). At this time, the extension frame (401) can limit the two sides of the pressing head (102). Therefore, when the pressing head (102) slides downward to the inside of the cavity of the mold (2), the downward sliding inertia of the extension frame (401) can be used to assist the pressing head (102) to align with the inside of the cavity of the mold (2); S4: When the extension frame (401) slides downward, the cross bar (402) at one end of the extension frame (401) slides synchronously, and the distance between the cross bar (402) and the hinge (501) increases. Therefore, the swing arm (5) can swing obliquely toward one side of the cross bar (402) through the hinge (501). At this time, the swing arm (5) can support one side of the cross bar (402), and then the swing arm (5) can support one side of the extension frame (401); S5: After the pre-pressing is completed, the pressure head (102) moves upward, and when the pressure head (102) moves upward, it drives one side of the extension frame (401) to tilt upward and return to its original position. At the same time, the weight of the weight (302) is greater than the overall weight of the extension frame (401) and the inclined plate (4). At this time, the weight (302) can swing downward and return to its original position by its own weight; S6: After the extension frame (401) slides upward, the extension frame (401) drives the cross bar (402) to slide toward the inside of the inclined plate (4), the distance between the cross bar (402) and the hinge (501) is shortened, and the swing arms (5) are synchronously tilted and swung through the hinge (501), and the distance between the swing arms (5) is increased; S7: The entire temperature of the pressing head (102) is increased by the electric heating wire, and then the pressing head (102) is pre-pressed, and the carrier plate and the chip are welded and fixed by the melted tin wire. After the welding is completed, the motor (103) rotates again, and then the above steps are repeated to form a cycle.
