Description

Technical Field

[0001] This utility model relates to the field of semiconductor processing and handling technology, and in particular to a handling mechanism for a glue application machine. Background Technology

[0002] Semiconductor processing requires adhesive application. In the current adhesive application machine's feeding process, the conveying mechanism consists of a motor-driven synchronous belt and a suction cup assembly. It uses a stepper motor with a built-in encoder to drive the synchronous belt to achieve material translation, and works with a lifting cylinder to complete vertical movement. The positioning accuracy of this structure is affected by mechanical clearance, usually only reaching ±1mm level. Moreover, the synchronous belt is a wear part and needs to be maintained and replaced regularly.

[0003] In the loading process of semiconductor adhesive application, the conveying mechanism consists of a motor-driven lead screw and nut assembly and a suction cup assembly. It uses a servo or stepper motor to drive the ball screw to complete the translation and loading / unloading of materials. This structure is complex to manufacture, has many parts, and costs twice as much as a cylinder. Moreover, its load capacity is lower than that of a high-thrust cylinder. In response, we designed a three-position material loading / unloading cylinder conveying mechanism. This equipment has a simple structure, small space, high precision, good reliability, and long service life, which greatly reduces the assembly, debugging, and subsequent maintenance costs for workers. Utility Model Content

[0004] This invention provides a conveying mechanism for a glue application machine, which solves the problems mentioned in the background.

[0005] To solve the above-mentioned technical problems, this utility model provides a conveying mechanism for a glue application machine, including a bracket, on which a linear guide rail A is fixedly installed. A pen-shaped cylinder II is installed on the top of the linear guide rail A, and a linear guide rail B is slidably installed on the inner side of the linear guide rail A. The output end of the telescopic rod of the pen-shaped cylinder II is connected to the linear guide rail B. A cylinder frame is slidably installed on one side of the linear guide rail B, and a Z-axis cylinder is installed on the cylinder frame. The output end of the telescopic rod at the bottom of the Z-axis cylinder is connected to a conveying frame. An adsorption detection component is installed on the conveying frame. A pen-shaped cylinder I is installed on the linear guide rail B, and the output end of the telescopic rod of the pen-shaped cylinder I is connected to...

[0006] Preferably, the adsorption detection component includes a lifting frame plate fixed to the bottom of the transport frame. The lifting frame plate is equipped with three sets of suction cups, each set of suction cups having two suction cups. A metal sensor and a photoelectric sensor are installed on both sides of the transport frame on the lifting frame plate.

[0007] Preferably, the metal sensor, photoelectric sensor, and suction cup of the suction cup assembly are all provided with screws at their tops. The screws pass through the openings on the lifting frame plate and are connected to threaded caps.

[0008] Preferably, two magnetic switches are installed on both the pen-shaped cylinder 2 and the pen-shaped cylinder 1, and the magnetic switches are located at both ends of the pen-shaped cylinder 2 and the pen-shaped cylinder 1, respectively.

[0009] Preferably, hydraulic dampers are installed at both ends of the linear guide rail A and the linear guide rail B.

[0010] Compared with related technologies, the conveying mechanism for a glue applicator provided by this utility model has the following advantages: 1. Improve production efficiency: The cylinder is driven by a single power source compressed air to perform translation and lifting movements, which can simultaneously complete the continuous actions of picking up and discharging materials. The response speed is fast and the production cycle is shortened.

[0011] 2. High flexibility: By adjusting the limit screw of the cylinder stroke or the limit nut of the buffer, the stroke of the transported products can be flexibly adjusted to adapt to different production needs.

[0012] 3. Saves space and cost: The cylinder-driven stepper feeding mechanism has a simple structure and fewer parts, which makes maintenance and upkeep more convenient and reduces manufacturing costs, especially in situations where multiple stops are required. In contrast, the method of using a motor to drive a lead screw is too complex and expensive.

[0013] 4. Stability and Reliability: Hydraulic dampers are installed on both sides of the cylinder to absorb vibrations after reaching the set point, increasing stability and ensuring reliable operation of the mechanism. They also integrate safety sensors and alarm systems to reduce the frequency of manual intervention and minimize human error. Attached Figure Description

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0017] Depend on Figures 1-4 The present invention includes a bracket 14, on which a linear guide rail A5 is fixedly mounted. A pen-shaped cylinder 2 is mounted on the top of the linear guide rail A5. A linear guide rail B7 is slidably mounted on the inner side of the linear guide rail A5. The output end of the telescopic rod of the pen-shaped cylinder 2 is connected to the linear guide rail B7. A cylinder frame 15 is slidably mounted on one side of the linear guide rail B7. A Z-axis cylinder 3 is mounted on the cylinder frame 15. The output end of the telescopic rod at the bottom of the Z-axis cylinder 3 is connected to a transport frame 11. An adsorption detection component is mounted on the transport frame 11. A pen-shaped cylinder 1 is mounted on the linear guide rail B7. The output end of the telescopic rod of the pen-shaped cylinder 1 is connected to the linear guide rail B7. The adsorption detection assembly includes a lifting frame plate 16 fixed to the bottom of the transport frame 11. The lifting frame plate 16 is equipped with three sets of suction cups 10, each set of suction cups 10 having two suction cups. A metal sensor 9 and a photoelectric sensor 8 are installed on both sides of the transport frame 11 on the lifting frame plate 16. Two magnetic switches 13 are installed on both pen-shaped cylinder 2 and pen-shaped cylinder 1, respectively located at both ends of pen-shaped cylinder 2 and pen-shaped cylinder 1. With the above structural design, the bracket 14 is installed at the designated feeding position. When the device is in operation, and feeding of the copper frame is required, the material is piled up at a suitable position on one side of the bracket 14. Paper materials can be placed on the side of the copper frame material. The piston rod of the pen-shaped cylinder 1 extends, pushing the linear guide rail B7 and the cylinder frame 15 towards the material area. When the piston rod reaches its extension limit, the magnetic switch 13 triggers a signal, stopping the action of cylinder 1. The piston rod of the Z-axis cylinder 3 extends, causing the conveying frame 11 to descend, bringing the suction cup assembly 10 closer to the material. Sensor 9 detects the copper frame, and photoelectric sensor 8 serves as an auxiliary verification to ensure the presence of the material. The suction cup assembly 10 is energized and adsorbs the copper frame. The piston rod of the Z-axis cylinder 3 retracts, and the conveyor frame 11 rises. When the magnetic switch 13 detects that the Z-axis cylinder 3 has retracted, the piston rod of the pen-shaped cylinder 1 retracts, pulling the material back to its initial position. After the magnetic switch 13 detects that the Z-axis cylinder 3 has retracted, the piston rod of the pen-shaped cylinder 1 retracts, pulling the material back to its initial position, the suction cup assembly 10 lowers the material to the processing position or transports it to the processing position on the conveyor belt, without limitation. Secondly, when feeding paper onto the carrier, the preceding steps are the same as those for the copper frame. Pen-shaped cylinder 1 extends, magnetic switch 13 is triggered and then stops, metal sensor 9 is not triggered, but photoelectric sensor 8 detects the presence of paper, the system determines it to be paper, and the piston rod of Z-axis cylinder 3 retracts and does not attract. When Z-axis cylinder 3 retracts to its position, magnetic switch is triggered, pen-shaped cylinder 2 extends, pushing linear guide rail B7 to move laterally to the dedicated paper feeding position, Z-axis cylinder 3 extends, suction cup assembly 10 is energized to attract paper, and then suction cup assembly 10 is released to the paper collection area after being reset by pen-shaped cylinder 1 and pen-shaped cylinder 2. It should be noted that the sensor structure and the control system structure corresponding to magnetic switch 13 used in this case are all existing conventional technologies, so the related linkages will not be described in detail.

[0018] The top of the metal sensor 9, the photoelectric sensor 8, and the suction cup of the suction cup assembly 10 are all provided with screws (not shown in the figure). The screws pass through the opening on the lifting frame plate 16 and are connected to a threaded cap 6, that is, the top of the metal sensor 9, the photoelectric sensor 8, and the suction cup assembly 10 are in contact with the bottom of the lifting frame plate 16.

[0019] Furthermore, this allows for the selection and installation of the metal sensor 9, photoelectric sensor 8, and suction cup assembly 10 after adjusting their positions, resulting in better applicability.

[0020] Hydraulic dampers 4 are installed at both ends of linear guide rails A5 and B7. Furthermore, hydraulic dampers 4 are installed on both sides of the cylinder to absorb vibrations after the specified time (referring to the movement of parts and resetting), increasing stability and ensuring reliable operation of the mechanism. Optionally, integrated safety sensors and alarm systems from existing technologies can be installed to reduce the frequency of manual intervention and minimize human error.
