Description

Technical Field

[0001] This utility model belongs to the field of chip bonding technology, and specifically relates to a controller electronic chip bonding device and an anti-displacement structure. Background Technology

[0002] During prolonged operation, existing electronic chip bonding devices are prone to clogging of the pores on the robotic suction cup surface due to continuous contact with chip surfaces or environmental impurities such as dust and particles. This clogging directly affects the uniform distribution of air pressure inside the suction cup, preventing it from evenly adsorbing the chip. This results in uneven force on the chip during gripping, causing tilting or even slippage. When the chip is gripped at an angle and placed in the target position, its positioning accuracy will significantly decrease, easily leading to serious problems such as chip misalignment, poor contact, or even damage to the chip's internal structure. Conventional solutions to this problem include periodically cleaning the suction cup surface manually, using higher-precision sensors to monitor the suction cup status in real time, or using an airflow backflushing device to clear pore blockages. However, manual cleaning is inefficient and difficult to maintain, and frequent disassembly may accelerate the aging of the suction cup; high-precision sensors will significantly increase equipment costs and maintenance difficulty; while airflow backflushing can alleviate the blockage problem, it has limited effect on removing micron-sized particles, and long-term use will lead to increased complexity of the air circuit system and higher maintenance costs. Therefore, we hope to design a chip bonding device with a novel structure to solve this problem. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a controller electronic chip bonding device and an anti-displacement structure to solve the problems mentioned in the background art.

[0004] This utility model is achieved through the following technical solution: a controller electronic chip bonding device and anti-offset structure, comprising: a frame, a bonding worktable for feeding and bonding is horizontally installed on the upper side of the frame, a gripping component for gripping chips and bonding is installed on the upper side of the frame, the gripping component includes a robot arm, and a mounting frame is provided at the end of the robot arm for mounting the gripping head for gripping the chips; A pusher is installed on the side of the mounting bracket away from the gripper head for installing a cleaning module to facilitate cleaning of the suction cups on the gripper head. A light source is installed on the upper left and upper right sides between the pusher and the gripper head to provide sufficient brightness for the vision sensor on the robotic arm to perform positioning.

[0005] In a preferred embodiment, the pushing component includes a lifting cylinder, which is installed on the side of the mounting frame away from the gripping head. A frame plate with an inverted L-shaped cross-section is installed laterally at its lower end. A propulsion cylinder is installed on the side of the frame plate away from the gripping head. In actual use, the side of the mounting box near the propulsion cylinder is fixedly connected to the propulsion cylinder through a double piston rod. The rear part of the mounting box can be guided and connected to the frame plate through a guide rod.

[0006] In a preferred embodiment, the cleaning module includes a mounting box, a small servo motor is mounted on the left side of the mounting box, and a lead screw is rotatably mounted inside the mounting box. The left end of the lead screw is connected to the small servo motor via a coupling shaft.

[0007] In a preferred embodiment, a rack is movably mounted inside the mounting box on the side near the frame plate via a nut and a screw, and multiple gears are horizontally mounted inside the mounting box on the side near the gripping head.

[0008] In a preferred embodiment, the multiple gears are rotatably mounted in the mounting box via bearings and a rotating shaft, and the multiple gears are meshed with a rack for transmission. The rotating shaft has a spline hole running vertically through it, and a cleaning rod is slidably mounted inside the shaft through the spline hole. The lower end of the cleaning rod is provided with a spline rod for engaging with the spline hole.

[0009] In a preferred embodiment, the upper outer wall of the cleaning rod is provided with a rubber layer and has spiral-structured plastic bristles. A miniature cylinder is installed on the left and right sides of the mounting box, and the lower ends of the two miniature cylinders are fixedly connected to a support plate. In actual use, the overall diameter of the upper side of the cleaning rod is slightly larger than the inner diameter of the suction cup vent on the gripping head. After the upper side of the cleaning rod is inserted into the suction cup vent, it can be aligned for cleaning. At the same time, the top of the cleaning rod can be set into a pointed cone shape to facilitate unblocking.

[0013] 2. The cleaning module effectively solves the problems of low efficiency and difficulty in guaranteeing the frequency of manual cleaning, and the possibility that frequent disassembly may accelerate the aging of the suction cup. It can automatically clean the suction cup on the gripping head when needed, effectively reducing the risk of blockage of the suction cup vents. As a result, when the gripping head grips and attaches the chip, blockage will not directly affect the uniform distribution of air pressure inside the suction cup, making it impossible for the suction cup to evenly adsorb the chip. This will cause uneven force on the chip during the gripping process, resulting in tilting or even sliding. It can prevent the chip from shifting during attachment. Attached Figure Description

Detailed Implementation

[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] As the first embodiment of this utility model: Please see Figures 1 to 5 A controller electronic chip bonding device and anti-offset structure include: a frame 100, a bonding worktable 200 for feeding and bonding is horizontally mounted on the upper side of the frame 100, and a gripping component 300 for gripping chips and bonding is mounted on the upper side of the frame 100. The gripping component 300 includes a robot arm 310, and a mounting frame 320 is provided at the end of the robot arm 310 for mounting a gripping head 330 for gripping chips. A pusher 350 is installed on the side of the mounting bracket 320 away from the gripper head 330 for installing the cleaning module 360 ​​to facilitate cleaning of the suction cups on the gripper head 330. A light source 340 is installed on the upper left and upper right sides between the pusher 350 and the gripper head 330 to provide sufficient brightness for the vision sensor on the robot arm 310 to perform positioning.

[0023] The pusher 350 includes a lifting cylinder, which is installed on the side of the mounting frame 320 away from the gripper head 330. A frame plate with an inverted L-shaped cross-section is installed laterally at its lower end. A pusher cylinder is installed on the side of the frame plate away from the gripper head 330. In actual use, the side of the mounting box 362 near the pusher cylinder is fixedly connected to the pusher cylinder through a double piston rod. The rear part of the mounting box 362 can be guided and connected to the frame plate through a guide rod.

[0024] Specifically, by setting the pusher 350, in actual use, before starting the machine or when stopping production, the user can lift the gripper head 330 on the mounting frame 320 (in actual use, the gripper head 330 is connected to the mounting frame 320 via a cylinder to achieve height adjustment), so that the bottom height of the gripper head 330 is greater than the top height of the cleaning module 360. Then, the pusher cylinder located on the frame plate can be activated to push the entire cleaning module 360 ​​to the bottom of the gripper head 330. Subsequently, the cleaning module 360 ​​can be activated to clean the suction cup on the gripper head 330. The setting of the pusher 350 facilitates the position adjustment of the cleaning module 360, so that it can extend to work when needed and retract when the equipment is working normally, thus avoiding obstructing the normal operation of the gripper head 330.

[0025] As a second embodiment of this utility model: Please see Figures 1 to 5 The cleaning module 360 ​​includes a mounting box 362. A small servo motor is mounted on the left side of the mounting box 362. A lead screw is rotatably mounted inside the mounting box 362. The left end of the lead screw is connected to the small servo motor via a coupling shaft.

[0026] A rack 367 is movably mounted inside the mounting box 362 on the side near the frame plate via a nut and a screw. Multiple gears 368 are horizontally mounted inside the mounting box 362 on the side near the gripper head 330.

[0027] Multiple gears 368 are rotatably mounted in the mounting box 362 via bearings and a rotating shaft 369, and multiple gears 368 are meshed with a rack 367 for transmission. The rotating shaft 369 has a spline hole running vertically through its interior, and a cleaning rod 363 is slidably mounted inside the spline hole. The lower end of the cleaning rod 363 is provided with a spline rod for engaging with the spline hole.

[0028] The cleaning rod 363 has a rubber layer on its upper outer wall and is equipped with spiral plastic bristles. A miniature cylinder 362 is installed on the left and right sides of the mounting box 362. The lower ends of the two miniature cylinders 362 are fixedly connected to a support plate. In actual use, the overall diameter of the upper side of the cleaning rod 363 is slightly larger than the inner diameter of the suction cup vent on the gripping head 330. After the upper side of the cleaning rod 363 is inserted into the suction cup vent, it can be aligned for cleaning. At the same time, the top of the cleaning rod 363 can be set into a pointed cone shape to facilitate unblocking.

[0029] Multiple blind holes are provided on the upper side of the tray. The number and distribution of the blind holes are matched with the number and distribution of the cleaning rods 363. The lower end of the cleaning rod 363 passes through the rotating shaft 369 and the mounting box 362 and extends into the blind hole on the tray. The upper end of the cleaning rod 363 passes through the rotating shaft 369 and the mounting box 362. The bottom of the cleaning rod 363 is rotatably connected to the blind hole.

[0030] The mounting box 362 has a suction channel 364 horizontally arranged on the front side of one end near the gripping head 330, which is connected to the external suction tube. Multiple suction holes 365 are opened downward on the upper side of one end of the mounting box 362 near the gripping head 330. The multiple suction holes 365 are respectively located on the front side of multiple cleaning rods 363, and the bottom of the multiple suction holes 365 is connected to the suction channel 364.

[0031] Based on the first embodiment described above, further, the cleaning module 360 ​​is configured such that, in actual use, after the mounting box 362 moves to the bottom of the gripping head 330 (when the push cylinder is at full stroke, the top of the cleaning rod 363 is exactly below the vent hole of the suction cup), the micro cylinder 362 is activated to lift the tray, thereby raising the cleaning rod 363 located inside the mounting box 362. Subsequently, the upper end of the cleaning rod 363 enters the suction cup of the gripping head 330 under the movement of the tray, and then the suction cup of the gripping head 330 is activated. The small servo motor on the left side of the mounting box 362 drives the rack 367 inside the mounting box 362 to move left and right. Since multiple gears 368 are meshed with the rack 367, they drive the multiple gears 368 and the rotating shaft 369 to rotate. Driven by the rotating shaft 369, the cleaning rod 363 can synchronously follow the forward and reverse rotation. During this process, the micro cylinder 362 can be controlled to drive the tray to move up and down, so that the top of the cleaning rod 363 can rotate up and down to clean the air hole of the suction cup through the plastic bristles. At the same time, the external suction device is activated to draw air out of the suction channel 364 through the suction tube, thereby creating negative pressure in the multiple suction holes 365 to suck up the cleaned dust and prevent it from re-adhering to the gripping head 330. This effectively solves the problems of low efficiency, difficulty in guaranteeing the frequency of manual cleaning, and the possibility of frequent disassembly accelerating the aging of the suction cup. It can automatically clean the suction cup on the gripping head 330 when needed, effectively reducing the risk of blockage of the suction cup vent holes. As a result, when the gripping head 330 grips and attaches the chip, blockage will not directly affect the uniform distribution of air pressure inside the suction cup, making it impossible for the suction cup to evenly adsorb the chip. This will cause uneven force on the chip during the gripping process, resulting in tilting or even sliding. This can prevent the chip from shifting during attachment.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
