[0029] Please refer to Figures 1 to 9 , which is a chip picking mechanism according to an embodiment of the present invention for picking up chips. The chip picking mechanism includes a device body 10, a moving mechanism 20, and a picking mechanism 30. The picking mechanism 30 is movably installed on the device body 10 through the moving mechanism 20. The picking mechanism 30 includes a picking motor 31 fixedly installed on the moving mechanism 20 and a picking assembly 32. The picking motor 31 includes an output shaft and a driving wheel 310 sleeved on the output shaft. The picking assembly 32 includes a transmission shaft 33. The driving wheel 310 and the transmission shaft 33 are in transmission connection. In this embodiment, the picking assembly 32 further includes a conveyor belt 34. The driving wheel 310 is in transmission connection with the transmission shaft 33 through the conveyor belt 34. When the picking assembly 32 needs to pick up a chip, the moving mechanism 20 is used to move the picking mechanism 30 to the corresponding position where the chip needs to be placed, and the picking motor 31 cooperates with the conveyor belt 34 to adjust the placement angle of the chip for the picking mechanism 30.

[0030] The working principle of the chip picking mechanism involved in the utility model is as follows: first, when it is necessary to grab the chip, the chip is grabbed by the grabbing component 32; the movable mechanism 20 drives the entire grabbing mechanism 30 to move, and transports the grabbed chip to the corresponding position where the chip needs to be placed; the output shaft of the grabbing motor 31 rotates, driving the grabbing drive wheel 310 mounted on the output shaft to rotate; since the grabbing drive wheel 310 and the transmission shaft 33 are connected through the conveyor belt 34, the rotation of the grabbing drive wheel 310 will drive the transmission shaft 33 to rotate through the conveyor belt 34; the rotation of the transmission shaft 33 ultimately realizes the adjustment of the chip placement angle by the grabbing mechanism 30 to ensure that the chip can be placed at the specified position at an accurate angle.

[0031] Compared with the prior art, the chip picking mechanism involved in the utility model does not require manual grasping. The grasping mechanism 30 can be accurately moved to the position where the chip is required to be placed through the movable mechanism 20. The precise adjustment of the placement angle by the grasping motor 31 and the conveyor belt 34 greatly improves the accuracy of chip placement and ensures the accuracy and reliability of the chip in subsequent processes. Through the multi-directional movement of the movable mechanism 20 and the angle adjustment of the grasping motor 31, it can adapt to the chip grasping and placement tasks of different specifications, shapes and position requirements, and has strong versatility and flexibility. Fast and accurate grasping and placement actions can reduce the chip processing time, thereby improving the production efficiency of the entire production line.

[0032] See also Figures 1 to 3, the movable mechanism 20 includes a Z-axis grasping slide rail 21 provided on the device body 10. An X-axis grasping bracket 22 is slidably arranged on the Z-axis grasping slide rail 21. An X-axis grasping slide rail 23 is provided on the X-axis grasping bracket 22. A Y-axis grasping bracket 24 is slidably arranged on the X-axis grasping slide rail 23. An X-axis grasping driving cylinder 25 for driving the Y-axis grasping bracket 24 is provided on the X-axis grasping bracket 22. A Y-axis grasping slide rail 26 is provided on the Y-axis grasping bracket 24. A Y-axis grasping base 27 is slidably arranged on the Y-axis grasping slide rail 26. A plurality of grasping members 28 are fixed on the Y-axis grasping base 27. A Y-axis grasping cylinder 29 for driving the Y-axis grasping base 27 is provided on the Y-axis grasping bracket 24. The cylinder barrel of the Y-axis grasping cylinder 29 is fixed on the Y-axis grasping bracket 24, and the piston rod of the Y-axis grasping cylinder 29 is connected to the Y-axis grasping base 27. When chip grasping operation is required, the entire action process is coordinated in the X, Y, and Z axes; in the Z-axis direction, the X-axis grasping bracket 22 moves up and down along the Z-axis grasping slide rail 21 on the device body 10, so as to realize the position adjustment of the grasping members 28 in the vertical direction; in the X-axis direction, the X-axis grasping driving cylinder 25 pushes the Y-axis grasping bracket 24 slidably arranged on the X-axis grasping slide rail 23 to move left and right, realizing the position change of the grasping members 28 in the horizontal transverse direction; in the Y-axis direction, the piston rod of the Y-axis grasping cylinder 29 extends and retracts, driving the Y-axis grasping base 27 slidably arranged on the Y-axis grasping slide rail 26 to move back and forth, further adjusting the position of the grasping members 28 in the horizontal longitudinal direction; through the precise movement in these three directions, the multiple grasping members 28 fixed on the Y-axis grasping base 27 can accurately reach the position where the chip is located, completing the grasping operation; it can adapt to the chip grasping requirements of different positions and postures, and has good adaptability in complex production environments; the fast and accurate multi-axis movement reduces the time required for grasping the chip, and can realize an efficient production process; by increasing the number of the grasping members 28 or adjusting the layout of the grasping members 28, it can conveniently adapt to different scales and types of production requirements.

[0033] Please refer to Figures 6 to 8 , the movable mechanism 20 further includes a plurality of guide columns 210. The guide columns 210 penetrate through the Y-axis grasping bracket 24 and are connected and fixed to the Y-axis grasping base 27. When the Y-axis grasping cylinder 29 pushes or pulls the Y-axis grasping base 27 to move on the Y-axis grasping slide rail 26, the guide columns 210 play an important guiding and supporting role; the guide columns 210 penetrate through the Y-axis grasping bracket 24 and are connected and fixed to the Y-axis grasping base 27, ensuring the linearity and stability of the Y-axis grasping base 27 during the movement; during the movement process, the guide columns 210 limit the possible shaking, rotation or deviation from the linear movement trend of the Y-axis grasping base 27, enabling it to move precisely along the predetermined Y-axis direction.

[0034] Please refer to Figures 4 to 6, the grasping assembly 32 further includes a transmission belt 34, and the driving wheel 310 is drivingly connected to the transmission shaft through the transmission belt 34; both ends of the grasping driving wheel 310 extend outward to form limiting steps 310A. The setting of the limiting steps 310A is mainly to limit and position the movement of the grasping driving wheel 310 in the axial direction; when the grasping driving wheel 310 rotates with the output shaft of the motor, the limiting steps 310A at both ends can prevent the gear ring from undergoing excessive displacement in the axial direction; ensure that a stable and effective driving connection is always maintained between the grasping driving wheel 310 and the conveyor belt 34, avoiding transmission instability or failure caused by axial movement; reduce the transmission faults that may be caused by the axial displacement of the gear ring, reduce the probability of equipment maintenance and downtime, and enhance the operation reliability of the entire chip picking mechanism; the limiting steps 310A can limit the installation positions of the components around the gear ring to a certain extent, which helps to optimize the structural layout of the entire grasping mechanism 30 and make it more compact.

[0035] Please refer to Figure 8 and Figure 9 , the grasping assembly 32 includes a grasping part 320 and a fixing part 321, the grasping part 320 and the fixing part 321 are movably connected, and an elastic connecting member 322 for quick replacement with the grasping part 320 is provided at the connecting end of the grasping part 320 and the fixing part 321; the elastic connecting member 322 is a spring buckle; the elastic connecting member 322 can also be an elastic coupling. When it is necessary to replace the grasping part 320, the operator applies a certain external force to cause the grasping part 320 to displace relative to the fixing part 321; due to the elastic connecting member 322 being provided at the connection port, when the external force is applied, the elastic connecting member 322 will undergo elastic deformation; the deformation of the elastic connecting member 322 provides a certain amount of buffering and yielding space, enabling the grasping part 320 to move smoothly relative to the fixing part 321 and finally achieve separation; when installing a new grasping part 320, align the connection port of the new grasping part 320 with the connection port of the fixing part 321, and then apply an appropriate pressure; at this time, the elastic connecting member 322 undergoes elastic deformation again to adapt to the docking of the connection ports; when the pressure is removed, the elastic connecting member 322 returns to its original state, and the generated elastic force tightly connects the grasping part 320 and the fixing part 321 together to achieve quick replacement; it is possible to quickly replace the grasping part 320, reduce the equipment downtime, so that the production line can operate more efficiently; it is possible to flexibly select and replace a suitable grasping part 320 according to different production requirements to adapt to various chip grasping scenarios; when the grasping part 320 is worn or damaged, it is possible to replace the grasping part 320 alone without replacing the entire grasping assembly 32, saving costs; the presence of the elastic connecting member 322 makes the replacement process relatively simple, and the operator does not need complex tools and high-difficulty operation skills, reducing the requirements for the operator's skill level.

[0036] Please refer to Figures 4 to 7, the Y-axis fixed base is of a "U" shape. The fixing parts 321 penetrate through the Y-axis grasping bracket 24 and the Y-axis grasping base 27 respectively. A first connecting part 323 and a second connecting part 324 are sleeved on the fixing parts 321 on the Y-axis grasping base 27, and the first connecting part 323 and the second connecting part 324 are respectively fixed to the Y-axis grasping base 27. The fixing parts 321 penetrate through the Y-axis grasping bracket 24 and the Y-axis grasping base 27 respectively, playing a role of connection and fixation to ensure the relative position stability between the two components; the first connecting part 323 and the second connecting part 324 sleeved on the fixing parts 321 further fix the fixing parts 321 and the Y-axis grasping base 27 together; when the Y-axis grasping cylinder 29 drives the Y-axis grasping base 27 to move, due to the penetrating connection of the fixing parts 321 and the fixing effects of the first connecting part 323 and the second connecting part 324, the Y-axis grasping base 27 can move stably along the fixing parts 321 without shaking, offsetting or dislocating; multiple connection and fixation methods greatly reduce the risk of loosening and falling off of the components during operation, improve the overall reliability of the equipment, and reduce the probability of faults.

[0037] Please refer to Figure 8 and Figure 9 , an elastic member 325 is sleeved outside the fixing part 321; the elastic member 325 is a spring; the elastic member 325 can also be rubber; the elastic member 325 can also be an elastic metal sheet. One end of the elastic member 325 abuts against one end of the first connecting part 323, and the other end of the elastic member 325 abuts against one end of the second connecting part 324. When the Y-axis grasping base 27 moves under the drive of the Y-axis grasping cylinder 29, the fixing part 321 will move accordingly; the elastic member 325 sleeved outside the fixing part 321 is squeezed by the first connecting part 323 and the second connecting part 324; during the movement, if encountering external force impact or unstable conditions, the elastic member 325 will absorb and buffer these energies through its own compression and extension; when the external force makes the Y-axis grasping base 27 tend to move excessively in a certain direction, the connecting part abutting against it will apply pressure to the elastic member 325, and the elastic member 325 compresses to generate a reverse elastic force, thereby restricting the excessive movement of the Y-axis grasping base 27 and playing a role of shock absorption and balance.

[0038] Please refer to Figure 4 and Figure 5, the chip picking mechanism further includes a chip positioning mechanism 40. The chip positioning mechanism 40 includes a Y-axis positioning slide rail 41 provided on the Y-axis grasping bracket 24. A positioning base 42 is slidably arranged on the Y-axis positioning slide rail 41, and a positioning member 43 is installed on the positioning base 42; a positioning driving mechanism for driving the movement of the positioning base 42 is installed on the Y-axis grasping mechanism 30. During the chip picking process, when it is necessary to inspect the chip, the positioning driving mechanism pushes the positioning base 42 to slide on the Y-axis positioning slide rail 41, thereby driving the positioning member 43 installed on the positioning base 42 to move to a specified position; the positioning member 43 can be various types of sensors or positioning devices, such as optical positioning devices, electrical positioning devices, etc.; after the positioning member 43 reaches the specified position, the position of the picked chip is positioned; after determining the chip position, the grasping mechanism 30 can continue subsequent operations, such as placing the chip at a specified position; if it is found through positioning that the chip position is deviated, the control system will issue an instruction to adjust the position or posture of the grasping mechanism 30 according to the degree and direction of the deviation to correct the position of the grasping mechanism 30.

[0039] The positioning driving mechanism includes a linear motor 440 fixedly installed on the Y-axis grasping bracket 24. The linear motor 440 includes a motor body and a lead screw. The motor body is fixedly installed on the Y-axis grasping bracket 24, and the lead screw is threadedly connected to the positioning base 42. When it is necessary to drive the positioning base 42 to move on the Y-axis positioning slide rail 41, the linear motor 440 starts to work; the motor body starts and drives the lead screw to rotate; since the lead screw is threadedly connected to the positioning base 42, the rotational motion of the lead screw is converted into the linear motion of the positioning base 42 along the Y-axis positioning slide rail 41; when the lead screw rotates clockwise, the positioning base 42 moves in one direction along the slide rail; when the lead screw rotates counterclockwise, the positioning base 42 moves in the opposite direction along the slide rail; by controlling the rotation direction, speed and rotation amount of the motor body, the moving direction, moving speed and moving distance of the positioning base 42 can be accurately controlled, so that the positioning member 43 installed on the positioning base 42 can accurately reach the required positioning position and perform the positioning operation at a suitable speed and stroke. It can achieve precise control of the moving direction, speed and distance of the positioning base 42, ensure that the positioning member 43 accurately reaches the required positioning position, and improve the accuracy and reliability of positioning; the start and stop of the motor body are rapid, and it can quickly drive the lead screw to rotate, so that the positioning base 42 can quickly respond and move to the specified position, improving the positioning efficiency; the rotational motion of the lead screw is converted into the linear motion of the positioning base 42, and the process is stable, reducing vibration and impact, which is beneficial to protecting the positioning member 43 and improving the positioning stability.

[0040] A positioning lens 45 is provided on the positioning base 42 opposite to the positioning member 43. The positioning lens 45 can clearly capture the chip in a timely manner, achieve accurate position determination, improve the accuracy of positioning; quickly obtain the position of the chip, reduce the time required for positioning, and thus improve the efficiency of the entire production or operation process.

[0041] The above only expresses the preferred technical solutions of the present utility model, and its description is relatively specific and detailed, but it should not be construed as a limitation to the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and the present utility model also intends to include these changes and modifications.
