Abstract
Description
Technical Field
[0001] This utility model relates to the field of semiconductor encapsulation technology, specifically a flip-type structure for a laser adhesive removal machine. Background Technology
[0002] Semiconductor molding is one of the key processes in semiconductor packaging. It is mainly used to protect chips from damage caused by external environments (such as humidity, mechanical stress, chemical corrosion, etc.) while achieving electrical connection and heat dissipation functions.
[0003] Laser adhesive removal technology primarily utilizes the high energy and precision of lasers to remove excess adhesive (mold flash) generated during the encapsulation process by irradiating it with a laser beam. The laser energy is absorbed by the excess adhesive, causing it to vaporize or decompose instantly, thus achieving a fast and precise adhesive removal effect.
[0004] In the semiconductor molding industry, flipping mechanisms typically use a rotating disk, which is slow, costly, and inefficient. Currently, a flipping structure is lacking that facilitates laser adhesive removal. Utility Model Content
[0005] The technical problem to be solved by this utility model is to provide a flip-type structure for a laser adhesive removal machine, which uses a flip motor and a lifting cylinder to flip the product, making it convenient to remove adhesive from both sides.
[0006] This utility model achieves its purpose through the following technical solution:
[0007] A flip-type structure for a laser adhesive removal machine, characterized by comprising: a base plate, wherein a motor plate is fixedly connected to the base plate, providing a stable mounting foundation for the entire device; a flip motor, fixedly connected to a reducer, wherein the output shaft of the flip motor is fixedly connected to the input shaft of the reducer, the reducer is fixedly connected to the motor plate, and the output shaft of the reducer is connected to a rotating ring; the flip motor transmits power and adjusts its speed through the fixed connection to the reducer, and the output shaft of the reducer drives the rotating ring to rotate, thereby realizing the flipping action of the product; a horizontal cylinder, wherein an L-shaped slide is fixedly connected to a finger cylinder mounting plate, the horizontal cylinder is fixedly connected to a cylinder adapter plate, and the cylinder adapter plate is fixedly connected to the rotating ring; and symmetrical finger cylinders, each fixedly connected to the finger cylinder mounting plate, wherein two fingers of each symmetrical finger cylinder are fixedly connected to grippers, and the grippers can achieve precise clamping and positioning of the workpiece through the action of the finger cylinders.
[0008] As a further limitation of this technical solution, the base plate is fixedly connected to symmetrical limiting plates to restrict the movement range of the flipping structure, prevent components such as the cylinder adapter plate from exceeding the predetermined angle during the flipping process, thereby avoiding accidents such as device damage and ensuring the reliability and safety of the flipping action.
[0009] As a further limitation of this technical solution, the symmetrical limiting plates are respectively fixedly connected to pads, which are made of rubber material to achieve limiting support for the cylinder adapter plate.
[0010] As a further limitation of this technical solution, the rotating ring is fixedly connected to four sensing plates evenly distributed along the circumference, and the motor plate is fixedly connected to at least two limiting slip rings spaced 90° apart. Each limiting slip ring is fixedly connected to a photoelectric switch, and the sensing plates are matched with the photoelectric switches. By detecting the position of the sensing plates through the photoelectric switches, the rotation angle of the rotating ring can be monitored in real time, thereby achieving precise control of the flipping action, ensuring that the workpiece can accurately reach the predetermined position during the flipping process, and improving the accuracy and efficiency of laser degumming.
[0011] As a further limitation of this technical solution, a mounting plate is also included, which is fixedly connected to a lifting cylinder, and the piston rod of the lifting cylinder is fixedly connected to the base plate. The function of the lifting cylinder is to drive the base plate and the entire flipping structure on it to move up and down through the extension and retraction of its piston rod. This lifting function allows for adjustment of the workpiece at different heights, facilitating cooperation with other components of the laser degumming equipment, meeting operational needs under different working conditions, and improving the versatility and flexibility of the device.
[0012] As a further limitation of this technical solution, the mounting plate is fixedly connected to four guide cylinders, and optical axes are fixedly connected to the four corners of the base plate, with each optical axis disposed within a corresponding guide cylinder. The cooperation of the guide cylinders and optical axes is used to guide and limit the lifting and lowering movement of the base plate, ensuring that the base plate can move smoothly and accurately up and down during the lifting process, avoiding shaking or deviation, and improving the operating accuracy and stability of the device.
[0013] Compared with related technologies, the flip-type structure of the laser degumming machine provided by this utility model has the following beneficial effects:
[0014] (1) This utility model uses finger cylinder to drive the gripper to clamp and release the product. Through the action of the horizontal cylinder, the gripper and the product it clamps move in the horizontal direction, so as to achieve precise positioning of the product in the laser degumming equipment and ensure that the workpiece can accurately reach the laser degumming area.
[0015] (2) The flipping motor of this utility model drives the rotating ring to rotate through the reducer, thereby realizing the flipping action of the product; by detecting the position of the sensor plate through the photoelectric switch, the rotation angle of the rotating ring can be monitored in real time, ensuring that the workpiece can accurately reach the predetermined position during the flipping process, thereby improving the accuracy and efficiency of laser degumming.
[0016] (3) This utility model achieves automated operation through the drive of motor and cylinder, reducing manual intervention and improving production efficiency and consistency. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Example 1: A flip-type structure for a laser adhesive removal machine includes: a base plate 9, which is fixedly connected to a motor plate 2, providing a stable mounting foundation for the entire device; a flip motor 1, fixedly connected to a reducer 7, the output shaft of the flip motor 1 being fixedly connected to the input shaft of the reducer 7, the reducer 7 being fixedly connected to the motor plate 2, and the output shaft of the reducer 7 being connected to a rotating ring 18. The flip motor 1 transmits power and adjusts its speed through the fixed connection to the reducer 7. The output shaft of the reducer 7 is connected to the rotating ring 18, thereby driving the rotating ring 18 to rotate and achieve the flipping action of the product; a horizontal cylinder 8, whose L-shaped slide is fixedly connected to a finger cylinder mounting plate 4, the horizontal cylinder 8 being fixedly connected to a cylinder adapter plate 3, and the cylinder adapter plate 3 being fixedly connected to the rotating ring 18; symmetrical finger cylinders 5, each fixedly connected to the finger cylinder mounting plate 4, with two fingers of each symmetrical finger cylinder 5 being fixedly connected to grippers 6. Through the action of the finger cylinders 5, the grippers 6 can achieve precise clamping and positioning of the workpiece.
[0023] The system also includes a mounting plate 11, which is fixedly connected to a lifting cylinder 13. The piston rod of the lifting cylinder 13 is fixedly connected to the base plate 9. The function of the lifting cylinder 13 is to drive the base plate 9 and its entire tilting structure to move up and down through the extension and retraction of its piston rod. This lifting function allows for adjustment of the workpiece at different heights, facilitating integration with other components of the laser degreasing equipment, meeting operational needs under different working conditions, and improving the versatility and flexibility of the device. In use, the mounting plate 11 is installed in the workshop using a bracket or similar support, the height of which must be greater than the stroke of the lifting cylinder 13.
[0024] The mounting plate 11 is fixedly connected to four guide cylinders 12, and optical axes 10 are fixedly connected to the four corners of the base plate 9. Each optical axis 10 is respectively set in the corresponding guide cylinder 12. The cooperation between the guide cylinders 12 and the optical axes 10 is used to guide and limit the lifting and lowering movement of the base plate 9, ensuring that the base plate 9 can move up and down smoothly and accurately during the lifting and lowering process, avoiding shaking or deviation, and improving the operating accuracy and stability of the device.
[0025] The flip motor 1 is a 400W Panasonic servo motor.
[0026] The reducer 20 is a KEDGE ZBT85-5-14-50-70-M4.
[0027] The horizontal cylinder 8 is an HLQ16X40SAS_0_+DMSH-1.
[0028] The finger cylinder 5 is an HFZ16.
[0029] The lifting cylinder 13 is model ACQ50x10S_0_DMSG2_.
[0030] The working principle of the flip-type structure of the laser adhesive removal machine provided by this utility model is as follows:
[0031] Initially, the upper and lower grippers 6 are far apart. By controlling the extension and retraction of the lifting cylinder 13, the grippers 6 are positioned at a suitable height. The horizontal cylinder 8 extends, bringing the grippers 6 closer to the product, placing the product within the gripper area. The finger cylinder 5 is then activated, causing the grippers 6 to clamp the product. The lifting cylinder 13 extends first, controlling the rotation motor 1 to rotate, causing the reducer 7 to rotate the rotating ring 18 180°, thus rotating the cylinder adapter plate 3, horizontal cylinder 8, finger cylinder mounting plate 4, finger cylinder 5, and grippers 6, causing the grippers 6 to rotate the product. The lifting cylinder 13 and horizontal cylinder 8 are activated, moving the grippers 6 and the product to the next process. The finger cylinder 5 is then activated, moving the grippers 6 away from the product. Finally, the horizontal cylinder 8 retracts, moving the grippers 6 and finger cylinder 5 away from the product.
[0032] Example 2: This example further elaborates on Example 1. The rotating ring 18 is fixedly connected to four evenly distributed sensing plates 19 along the circumference. The motor plate 2 is fixedly connected to at least two limiting slip rings 17 spaced 90° apart. Each limiting slip ring 17 is fixedly connected to a photoelectric switch 16, and the sensing plates 19 are matched with the photoelectric switches 16. By detecting the position of the sensing plates 19 through the photoelectric switches 16, the rotation angle of the rotating ring 18 can be monitored in real time, thereby achieving precise control of the flipping action. This ensures that the workpiece accurately reaches the predetermined position during the flipping process, improving the accuracy and efficiency of laser degumming.
[0033] The photoelectric switch 16 and the flip motor 1 are electrically connected to the controller. The controller model is STM32F103VCT6.
[0034] The working principle of the flip-type structure of the laser adhesive removal machine provided by this utility model is as follows:
[0035] In the initial state, one sensor 19 is in the slot of the photoelectric switch 16. When rotating, the photoelectric switch 16 detects that the third sensor 19 has entered its slot, and the flipping action is completed. The controller then shuts off the flipping motor 1.
[0036] Example 3: This example is a further elaboration based on Example 1 or 2. The base plate 9 is fixedly connected to a symmetrical limiting plate 14, which limits the range of motion of the flipping structure and prevents components such as the cylinder adapter plate 3 from exceeding the predetermined angle during the flipping process, thereby avoiding accidents such as device damage and ensuring the reliability and safety of the flipping action.
[0037] The symmetrical limiting plates 14 are respectively fixedly connected to the pads 15, which are made of rubber material, to achieve limiting support for the cylinder adapter plate 3.
[0038] The working principle of the flip-type structure of the laser adhesive removal machine provided by this utility model is as follows:
[0039] After the cylinder adapter plate 3 completes the flipping action, it contacts the pad 15.
