[0030] To facilitate understanding of the present invention, the present invention will be described more fully below with reference to the accompanying drawings. Preferred embodiments of the present invention are shown in the accompanying drawings. However, the present invention may be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and comprehensive understanding of the present disclosure.

[0031] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly attached to the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one skilled in the art to which this invention pertains. The terms used in this specification of the present invention are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0033] refer to Figure 1The present invention discloses a head 10 of a chip placement machine, which is movably mounted on a body of the chip placement machine (not shown). The chip placement machine can be used to place surface mount components onto a circuit substrate. Surface mount components include, but are not limited to, LEDs. During the placement process, the loading mechanism of the chip placement machine drives the circuit substrate to the placement area. The head 10 can move relative to the body of the chip placement machine. After obtaining the surface mount components, the head 10 places the surface mount components onto the circuit substrate in the placement area.

[0034] Combined with Figure 2 and Figure 3 , the machine head 10 includes a frame 100, at least two suction nozzle assemblies 200 and a clamping mechanism 300. Exemplarily, the machine head 10 includes 9 suction nozzle assemblies 200, which are arranged in a row on the frame 100 along the loading direction, and each suction nozzle assembly 200 can work independently, so that 9 surface mount components can be sucked at a time and subsequent mounting processing can be performed to improve the efficiency of the mounting processing. In other embodiments, the number of suction nozzle assemblies 200 can be increased or decreased. Each suction nozzle assembly 200 includes a first driver 210 and a suction nozzle 220 linked to the output end of the first driver 210. The first driver 210 is connected to the frame 100 to drive the suction nozzle 220 to rise and fall relative to the frame 100, and the suction nozzle 220 is used to suck surface mount components. In some embodiments, the first driver 210 is a linear motor, and its output shaft can be regarded as the output end of the motor. The linear motor is relatively small in size and has a relatively high control accuracy for the linear lifting motion of the nozzle assembly 200 , thereby improving the accuracy of surface mounting.

[0035] The clamping mechanism 300 is detachably connected to the frame 100 and includes a clamping jaw 310 that can be driven to rise and fall relative to the frame 100 to grasp surface mount components. Specifically, the clamping mechanism 300 may include a mounting platform 320 and a second driver 330, wherein the second driver 330 is connected to the mounting platform 320, and the mounting platform 320 is detachably connected to the frame 100. The clamping jaw 310 is linked to the output end of the second driver 330. The second driver 330 may be a cylinder, and the piston rod of the cylinder can be regarded as the output end. In other embodiments, the clamping mechanism 300 can use a pneumatic clamping jaw. By controlling the flow of gas into or out of the second driver 330, the opening and closing of the clamping jaw 310 can be controlled, and thus can be used to grasp surface mount components. The pneumatic clamping jaw 310 is a relatively mature technology and will not be described in detail here. In other embodiments, the second driver 330 may also use a hydraulic cylinder, which means that the clamping mechanism 300 can use a hydraulic clamping jaw.

[0036] The mounting platform 320 and the frame 100 can be detachably connected using threaded fasteners or other means. When the gripping method is not required to grasp surface mount components, the entire clamping mechanism 300 can be removed from the head 10 to reduce the weight and volume of the entire head 10, thereby reducing energy consumption. When the clamping mechanism 300 is required, the clamping mechanism 300 is installed on the frame 100 via the mounting platform 320, thereby meeting the requirements of grasping surface mount components for placement processing. This modular design of the clamping mechanism 300 can enhance its flexibility.

[0037] Further, combined Figure 4 The clamping mechanism 300 includes a third driver 340 and a fourth driver 350 connected to the mounting platform 320. The output end of the third driver 340 is linked to the second driver 330 to drive the second driver 330 and the clamping jaw 310 to rotate relative to the mounting platform 320. The output end of the fourth driver 350 is linked to the second driver 330 to drive the second driver 330 and the clamping jaw 310 to rise and fall relative to the mounting platform 320. The third driver 340 can be a stepper motor. Its output end, i.e., the output shaft of the motor, can be linked to the second driver 330 via a transmission belt to control the rotation of the second driver 330 and the clamping jaw 310 relative to the mounting platform 320. This can then adjust the posture of the surface mount component after grasping it to meet the placement positioning requirements. The fourth driver 350 can be a linear motor, and the fourth driver 350 can adopt the same model of linear motor as the first driver 210. That is, the fourth driver 350 and the first driver 210 are interchangeable, facilitating maintenance of the fourth driver 350.

[0038] Combined with Figure 4 and Figure 5The clamping mechanism 300 includes a connector 360 and a hollow rod 370. The connector 360 is sealedly connected to one end of the hollow rod 370 and is linked to the output end of the fourth actuator 350. The hollow rod 370 slidably engages with the mounting platform 320. The opposite end of the hollow rod 370 is connected to the second actuator 330. The hollow rod 370 is linked to the output end of the third actuator 340 to be driven to rotate relative to the mounting platform 320. The connector 360 defines a first air port 360a, which is connected to the second actuator 330 through the hollow rod 370. The connector 360 can be connected to an external air source, which in turn communicates with the second actuator 330 through the interior of the hollow rod 370, thereby controlling the opening and closing of the clamping jaw 310. A sealing ring can be installed at the end of the hollow rod 370 and inserted into the connector 360 to achieve a sealed connection between the hollow rod 370 and the connector 360. When the third driver 340 drives the clamp 310 to rotate, the hollow rod 370 rotates relative to the connector 360, and the sealing ring ensures the air tightness between the hollow rod 370 and the connector 360 to prevent gas leakage, thereby ensuring the reliability of the clamp 310.

[0039] Taking the fourth actuator 350 as a linear motor, for example, the connector 360 can be directly fixedly connected to the output end of the fourth actuator 350. When the machine head 10 is in operation, the fourth actuator 350 operates and drives the hollow rod 370 downward through the connector 360. The hollow rod 370 then drives the second actuator 330 and the clamp 310 downward. When the air source is activated, the clamp 310 first opens and approaches the surface mount component on the loading mechanism, and then closes to grasp the surface mount component. For example, air is input into the second actuator 330, causing the clamp 310 to open; air is removed from the second actuator 330, causing the clamp 310 to close. After the clamp 310 grasps the surface mount component, the fourth actuator 350 again drives the clamp 310 and the second actuator 330 upward through the connector 360 and the hollow rod 370. After the machine head 10 moves to the placement area, the clamp 310 can descend again to place the surface mount component on the predetermined position of the substrate.

[0040] The surface of the hollow rod 370 can be recessed to form a guide groove extending along its length. The hollow rod 370 can be mounted with a pulley and the inner side of the pulley has a protrusion that matches the guide groove. The cooperation between the protrusion and the guide groove can be used to apply torque to the hollow rod 370, that is, the third driver 340 can drive the hollow rod 370 to rotate through the transmission belt and the pulley; in the process of the fourth driver 350 driving the hollow rod 370 to rise and fall, the protrusion of the pulley moves along the guide groove, and the hollow rod 370 can be smoothly raised and lowered without interference of the pulley with the lifting and lowering movement of the hollow rod 370.

[0041] Continue to refer Figure 5In some embodiments, a waist-shaped hole 360b is provided at the output end of the fourth driver 350 and one of the connectors 360, and the waist-shaped hole 360b is used to pass a fastener to achieve a fixed connection between the output end of the fourth driver 350 and the connector 360, and the waist-shaped hole 360b is used to adjust the relative position of the output end of the fourth driver 350 and the connector 360. In an embodiment of the present application, the fastener may be a bolt, and the side of the connecting head 360 away from the clamping jaw 310 has two waist-shaped holes 360b, and the two waist-shaped holes 360b are arranged at intervals along the extension direction of the hollow rod 370, and the long axis or long symmetry axis of the waist-shaped hole 360b is perpendicular to the extension direction of the hollow rod 370, so that the position of the fastener in the long axis direction of the waist-shaped hole 360b can be fine-tuned, thereby adjusting the relative position of the hollow rod 370 and the output end of the fourth driver 350, ensuring that the hollow rod 370 and the output end of the fourth driver 350 are collinearly arranged, preventing the hollow rod 370 from deflecting during the lifting process and causing the moving parts to get stuck or wear, resulting in a decrease in mounting accuracy. Compared to circular holes, the waist-shaped hole 360b structure can reduce the assembly precision requirements between the connector 360 and the output end of the fourth actuator 350, lowering the relative position precision requirements between the two waist-shaped holes 360b. This reduces the machining precision requirements for the connector 360, avoiding excessively high assembly precision requirements for the connector 360 and resulting in excessively high machining costs. Furthermore, after the connector 360 is assembled with the hollow rod 370, it can be pre-assembled with the output end of the fourth actuator 350. Based on the test run results, the assembly position of the connector 360 and the output end of the fourth actuator 350 can be further adjusted to ensure smooth operation of the clamping mechanism 300.

[0042] In particular, in some embodiments, a deformable body, such as a silicone ring or rubber ring, can be embedded in the waist-shaped hole 360b. A fastener is disposed through the deformable body and securely connects the connector 360 to the output end of the fourth actuator 350. The deformable body can further reduce the machining precision requirements of the waist-shaped hole 360b and adaptively deform in the transverse direction (perpendicular to the extension direction of the hollow rod 370) and longitudinal direction (parallel to the extension direction of the hollow rod 370) during the raising and lowering of the hollow rod 370. This absorbs shock and reduces vibration while also minimizing shaking of the output end of the fourth actuator 350 and the connector 360 during the reciprocating raising and lowering process, thereby preventing wear or loosening of the fastener, which could reduce mounting precision. Furthermore, due to the presence of the deformable body, even if the assembly errors between the fourth actuator 350 and the mounting platform 320, the connector 360 and the fourth actuator 350, or the hollow rod 370 and the connector 360 result in an error in the parallelism between the extension direction of the hollow rod 370 and the output end of the fourth actuator 350, the deformable body can still achieve an elastic connection between the connector 360 and the fourth actuator 350, and the lateral and longitudinal adaptive deformation of the deformable body ensures smooth lifting and lowering of the hollow rod 370. In other words, the provision of the deformable body can further reduce the assembly precision requirements between the hollow rod 370 and the connector 360, the connector 360 and the fourth actuator 350, and the fourth actuator 350 and the mounting platform 320, thereby ensuring the operational reliability and service life of the clamping mechanism 300.

[0043] refer to Figure 4 Combined with Figure 6The clamping mechanism 300 may further include an open clamping block 380, which is detachably connected to the end of the hollow rod 370 away from the connector 360. The second actuator 330 is fixedly connected to the open clamping block 380. The open clamping block 380 has a second air port 380a that communicates with the interior of the hollow rod 370. The second air port 380a is connected to the second actuator 330. The cross-section of the open clamping block 380 is approximately inverted T-shaped, with the width of the upper end 381 being smaller than the width of the lower end 383. The upper end 381 of the open clamping block 380 is circumferentially provided with an opening 380b, so that a portion of the upper end 381 can be opened and closed relative to another portion. The hollow rod 370 can be inserted into the opening 380b of the upper end 381 of the open clamping block 380 and is clamped to the hollow rod 370 by fasteners such as bolts or screws, thereby achieving a fixed connection between the open clamping block 380 and the hollow rod 370. The structure of the opening clamp 380 is relatively simple, making it easy to securely connect it to the hollow rod 370. The lower end 383 of the opening clamp 380 can be securely connected to the second actuator 330 using fasteners such as screws. A second air port 380a can be provided at the lower end 383 or on a side of the opening clamp 380. This second air port 380a can be connected to the second actuator 330 via a pipe, thereby connecting the interior of the hollow rod 370 to the second actuator 330 and controlling the opening and closing of the clamping jaw 310.

[0044] With the above structural arrangement, the second air port 380a can be connected to the second driver 330 through a shorter pipe. When the third driver 340 drives the second driver 330 and the clamp 310 to rotate, the pipe section also rotates synchronously. The shorter pipe will not produce torsional deformation, thereby avoiding loosening of the connection between the pipe and the second air port 380a to cause gas leakage, and also avoiding reserving a larger avoidance space for the movement of the pipe in space, which leads to an increase in the size of the entire head 10, thereby improving the compactness of the head 10 and ensuring the working reliability of the clamp mechanism 300.

[0045] refer to Figure 3 、 Figure 4 Combined with Figure 7In some embodiments, the clamping mechanism 300 may further include a sleeve 391 and a limit seat 393, the limit seat 393 is connected to the mounting platform 320 and has a limit groove 393a, the sleeve 391 is accommodated in the limit groove 393a and is connected to the limit seat 393, the hollow rod 370 is passed through the sleeve 391 and adapted to the sleeve 391, and the end of the hollow rod 370 away from the connecting head 360 extends out of the side of the limit seat 393 away from the connecting head 360. The outer diameter of the sleeve 391 is larger than the outer diameter of the hollow rod 370, and the inner diameter of the sleeve 391 can be equivalent to the outer diameter of the hollow rod 370. Combined with the setting of the side of the hollow rod 370 away from the connector 360 extending out of the side of the limit seat 393 away from the connector 360, the limit seat 393 and the sleeve 391 can act as a fulcrum between the connector 360 and the second driver 330, and realize the guidance and limitation of the hollow rod 370, preventing the longer hollow rod 370 from easily deflecting during the lifting process, thereby ensuring the accuracy of the mounting.

[0046] Continue to refer Figure 4 The clamping mechanism 300 may also include a return trigger 395 fixedly connected to the mounting platform 320. The return trigger 395 is located between the connecting head 360 and the limit seat 393. When the fourth driver 350 drives the connecting head 360, the hollow rod 370, the second driver 330 and the clamping jaw 310 to descend, the return trigger 395 is used to contact the connecting head 360 to drive the connecting head 360, the hollow rod 370, the second driver 330 and the clamping jaw 310 to reset through the fourth driver 350. Specifically, in an embodiment of the present application, the placement machine may include a processor, which is communicatively connected to the fourth driver 350 and can detect the load size of the output end of the fourth driver 350. When the fourth driver 350 drives the connector 360, the hollow rod 370, the second driver 330 and the clamp 310 to descend, when the return trigger 395 contacts the connector 360, the load of the fourth driver 350 suddenly increases. When the load is greater than the preset value, it means that the connector 360 is in contact with the return trigger 395, that is, the connector 360 has descended to the extreme position. The processor can respond to the signal and control the hollow rod 370 to rise and return to prevent the clamp 310 from descending beyond the threshold and causing damage to the equipment or substrate.

[0047] It is understood that the fourth driver 350 may be omitted. Figure 8In some embodiments, the clamping mechanism 300 includes a third driver 340 and a switching component 397 connected to the mounting platform 320. The output end of the third driver 340 is linked to the second driver 330 to drive the second driver 330 and the clamping claw 310 to rotate relative to the mounting platform 320. The switching component 397 has a first state and a second state. In the first state, the switching component 397 is linked to the output end of the first driver 210 to drive the second driver 330 and the clamping claw 310 to rise and fall relative to the mounting platform 320 through the first driver 210; in the second state, the switching component 397 is disengaged from the output end of the first driver 210.

[0048] Illustratively, the switching assembly 397 may include a cylinder 3971 and a switching member 3973. The switching member 3973 is linked to the output of the cylinder 3971, which is in turn connected to the connector 360. A docking port (not shown) may be provided at the output of the first actuator 210 closest to the gripper mechanism 300. When the cylinder 3971 is connected to an air source, it drives the switching member 3973 into the docking port. When the first actuator 210 drives the suction nozzle 220 upward or downward, it simultaneously drives the hollow rod 370, the second actuator 330, and the gripper 310 upward or downward, thereby enabling the gripper 310 to grasp surface mount components for placement processing. When the gripper mechanism 300 is no longer needed, the cylinder 3971 drives the switching member 3973 out of the docking port, disengaging the switching assembly 397 from the output of the first actuator 210. The gripper mechanism 300 no longer participates in the gripping process, thereby improving ease of use. This embodiment can reuse the first driver 210 and save the number of linear motors, thereby achieving a compact structure of the handpiece 10 and reducing the cost of the handpiece 10.

[0049] The above-mentioned head 10 can be used in a placement machine. The head 10 includes a frame 100, at least two suction nozzle assemblies 200 and a clamping mechanism 300. Each suction nozzle assembly 200 includes a first driver 210 and a suction nozzle 220 linked to the output end of the first driver 210. The first driver 210 is connected to the frame 100 to drive the suction nozzle 220 to rise and fall relative to the frame 100. The suction nozzle 220 is used to absorb surface mount components. The clamping mechanism 300 is detachably connected to the frame 100 and includes a clamping claw 310 that can be driven to rise and fall relative to the frame 100 to grasp surface mount components. For surface mount components suitable for absorption, the suction nozzle assembly 200 can absorb such surface mount components on the loading mechanism of the placement machine for placement processing; for some special-shaped placement components, they can be clamped by the clamping mechanism 300 and then placed. In other words, the same head 10 of the present application is suitable for both sucking surface mount components for processing and grabbing mount components for processing, thus having higher versatility and compactness. Compared with using two independent placement machines or heads for processing, it can save equipment costs and space occupancy.

[0050] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0051] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.
