[0001] This application relates to the field of mechanical equipment technology. More specifically, this application relates to a pusher mechanism. Background Technology

[0002] In the chip mounting process, the chip needs to be precisely picked up from the diced wafer and placed in the corresponding position on the substrate, and then firmly bonded with adhesive. The pick-and-place machine plays a core role in this process. It can place components at high speed and high precision, and successfully complete important steps such as positioning, alignment, flip-chip mounting and continuous mounting.

[0003] In practice, the step of transferring the wafer from the magazine to the chip mounter requires an automatic wafer pusher mechanism. However, existing automatic wafer pushers have many problems, such as the lack of effective support for the pusher rod assembly during operation, which makes it prone to sagging and affects the accuracy and stability of wafer pushing.

[0036] The specific embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0037] like Figure 1 As shown, in some embodiments, this application provides a pusher mechanism 100, including: a pusher base plate 101, the upper surface of which has a first guide rail 1011 extending along its length direction, and a first slider disposed within the first guide rail 1011; a first support portion 1012 disposed at one end of the first guide rail 1011, and a roller 1013 disposed on the first support portion 1012; a pusher assembly 102, the first end of which is connected to the first slider in its length direction, and the lower surface of the second end of which is slidably connected to the roller 1013; a first conveying assembly 103, the first conveying assembly 104... 03 includes two spaced-apart rotating wheels 1031 and a conveyor belt 1032 sleeved on the rotating wheels 1031, wherein the conveyor belt 1032 is parallel to the length direction of the push plate base plate 101; a first pressure block 1033 is fixedly disposed on the conveyor belt 1032, and the first pressure block 1033 is fixedly connected to the push rod assembly 102; and a drive device 105, which is connected to the first conveying assembly 103, so that the conveyor belt 1032 drives the push rod assembly 102 to move forward or backward along the length direction of the push plate base plate 101, so that the push rod assembly 102 removes the carrier from the magazine.

[0038] The pusher mechanism 100 in this solution includes a pusher base plate 101, a pusher assembly 102, a first conveying assembly 103, and a drive device 105. Specifically, the pusher base plate 101 is a rectangular plate structure with a preset length, a preset width, and a preset height, wherein the length direction refers to the attached... Figure 1The X-axis direction shown in the figure refers to the width direction. Figure 1 The Y-axis direction shown in the figure refers to the height direction. Figure 1 The Z-axis direction is shown in the figure. The upper surface of the push plate base plate 101 has a first guide rail 1011 extending along the length direction, and a first slider is provided in the first guide rail 1011. A first support portion 1012 is provided at one end of the first guide rail 1011 along the length direction, and a roller 1013 connected by a fixed shaft 1015 is provided on the first support portion 1012.

[0039] The push rod assembly 102 in this design is used to remove the carrier from the magazine. It also has a preset length, preset width, and preset height, and the extension directions of the push rod assembly 102 and the push plate base 101 are the same. The first end of the push rod assembly 102 in the length direction is fixedly connected to the first slider, which guides it to move linearly on the first guide rail 1011. The lower surface of the second end of the push rod assembly 102 in the length direction is slidably connected to the roller 1013 of the first support part 1012. That is to say, in this design, the roller 1013 supports the second end of the push rod assembly 102 to prevent it from sagging during reciprocating motion.

[0040] The first conveying assembly 103 in this solution includes two rotating wheels 1031 spaced apart along the X-axis, and a conveyor belt 1032 sleeved on the rotating wheels 1031, wherein the conveyor belt 1032 is parallel to the length direction of the push plate base plate 101. A first pressure block 1033 is fixedly disposed on the conveyor belt 1032, and the first pressure block 1033 is fixedly connected to the push rod assembly 102, thereby enabling the conveyor belt 1032 to drive the push rod assembly 102 to move.

[0041] It is worth noting that in this design, one of the two rotating wheels 1031 is a driving wheel and the other is a driven wheel. The drive device 105 is a motor, which is connected to the driving wheel. In use, the motor rotates, driving the driving wheel to rotate. The conveyor belt 1032 drives the push rod assembly 102 to move forward or backward along the length of the push plate base plate 101. The second end of the push rod assembly 102 contacts the carrier in the magazine, removing the carrier from the magazine onto the pick-and-place machine.

[0042] In this solution, the second end of the push rod assembly 102 in the pusher mechanism 100 contacts the first support part 1012 through the roller 1013, forming rolling friction. This effectively solves the problem that the push rod assembly 102, as a cantilever structure, is prone to sagging during reciprocating motion, ensuring the smooth operation of the push rod assembly 102 and the accuracy of the pusher.

[0043] like Figure 2As shown, in one specific embodiment, the push rod assembly 102 includes a push rod head 1021, a push rod head fixing block 1022, and a push rod 1023 connected in sequence, wherein the push rod head 1021 and the push rod head fixing block 1022 are connected by an elastic buffer 1024. The push rod head fixing block 1022 is provided with a mounting groove 1027, and the elastic buffer 1024 is disposed in the mounting groove 1027; the push rod head 1021 is provided with an extension 1025 and a limiting portion 1026, the limiting portion 1026 being confined within the mounting groove 1027 and connected to the elastic buffer 1024.

[0044] The push rod assembly 102 in this solution includes a push rod head 1021, an elastic buffer 1024, a push rod head fixing block 1022, and a push rod 1023 connected in sequence. Specifically, the front end of the push rod head 1021 is used to directly contact and push the carrier plate, and the rear end is provided with a rod-shaped extension 1025 extending towards the push rod head fixing block 1022. The end of the extension 1025 is connected to a limiting part 1026. The push rod head fixing block 1022 is provided with a mounting groove 1027 whose axis is consistent with the movement direction of the push rod assembly 102. The opening of the mounting groove 1027 is set towards the push rod head 1021, and the elastic buffer 1024 is also provided in the mounting groove 1027.

[0045] In this design, the elastic buffer 1024 is a spring. One end of the spring is fixed in contact with the bottom of the mounting groove 1027, and the other end is fixed in contact with the limiting part 1026 of the push rod head 1021. Specifically, the extension 1025 of the push rod head 1021 passes through the mounting groove 1027 of the push rod head fixing block 1022, the limiting part 1026 is limited within the mounting groove 1027 and abuts against one end of the spring, and the other end of the spring abuts against the bottom of the groove.

[0046] It is worth noting that the cross-sectional area of ​​the limiting part 1026 in the Z-axis direction is greater than the cross-sectional area of ​​the extension part 1025 in the Z-axis direction in this solution. In addition, the shape of the limiting part 1026 is not specifically limited in this solution; for example, the limiting part 1026 can be a circular or square boss.

[0047] In this design, a spring is provided between the push rod head 1021 and the push rod head fixing block 1022. When the push rod assembly 102 pushes the carrier plate, the elastic deformation of the spring provides a buffer space, preventing the push rod head 1021 from directly contacting the carrier plate (i.e., rigid collision). In other words, this design absorbs the impact force through the compression of the spring, preventing the carrier plate from being damaged or displaced due to excessive impact force.

[0048] like Figure 1 As shown, in a specific implementation, a displacement sensor 108 is respectively provided at both ends of the first guide rail 1011; and a sensing baffle 109 is provided on the push rod assembly 102.

[0049] In this design, two displacement sensors 108 are symmetrically mounted at both ends of the first guide rail 1011 on the pusher plate 101 to monitor the extreme positions of the pusher assembly 102. Simultaneously, a sensing baffle 109 is fixedly mounted on the pusher assembly 102. This sensing baffle 109 can be a metal sheet or a reflective sheet, etc. The position of the sensing baffle 109 precisely corresponds to the sensing range of the displacement sensors 108, ensuring that when the pusher assembly 102 moves to its extreme positions, the sensing baffle 109 can trigger the sensor action through physical obstruction or signal reflection.

[0050] In this design, the displacement sensor 108 monitors whether the push rod assembly 102 has reached the predetermined position, and the sensing baffle 109 acts as a trigger element to generate a position feedback signal, achieving precise positioning monitoring. Furthermore, the feedback signal can also control the start, stop, or direction of the drive device 105. That is, when the push rod assembly 102 reaches the endpoint and ejects the carrier plate, the sensor signal triggers the motor to reverse, causing it to return to the starting point. Upon returning to the starting point, the signal triggers the motor to stop or wait for a command.

[0051] like Figure 1 and Figure 3 As shown, in one specific embodiment, the pusher mechanism 100 further includes a first adjustment component 106. The first adjustment component 106 includes a base 1061 and a pad 1065 that move relative to each other along the width direction of the pusher base plate 101, and a fastener 1067 that connects the two together when they move to a preset position. The upper surface of the pad 1065 is connected to the lower surface of the pusher base plate 101. The base 1061 includes a first panel 1062 and a second panel 1063 that is vertically disposed above the first panel 1062. The first panel 1062 is disposed parallel to the pusher base plate 101. The second panel 1063 has a notch 1064 that extends along the width direction of the pusher base plate 101. The pad 1065 has a connecting rod 1066 with a preset extension length. After the connecting rod 1066 drives the pusher base plate 101 to move to the preset position, the fastener 1067 limits it in the notch 1064.

[0052] In this design, the pusher mechanism 100 further includes a first adjustment component 106, which includes a base 1061, a pad 1065, and fasteners 1067. Specifically, the base 1061 includes a first panel 1062 parallel to the pusher base plate 101, and a second panel 1063 vertically disposed above the first panel 1062. The second panel 1063 has a notch 1064 extending along the width direction of the pusher base plate 101.

[0053] The upper surface of the pad 1065 is detachably connected to the lower surface of the push plate base 101 by bolts or other means, and the lower surface of the pad 1065 abuts against the upper surface of the base 1061. Additionally, a connecting rod 1066 is provided at one end of the pad 1065 in the Y-axis direction, wherein the extension direction of the connecting rod 1066 is consistent with the width direction of the push plate base 101. During installation, the connecting rod 1066 is inserted into the notch 1064 on the second surface, and then the pad 1065 is moved relative to the base 1061 to a preset position. Finally, the two are rigidly connected by tightening the fastener 1067, thereby fixing the push plate base 101 to a specific position in the Y-axis direction.

[0054] In this design, to prevent displacement between the pad 1065 and the base 1061, a protrusion extending along the Y-axis is provided on the upper surface of the first panel 1062, while the lower surface of the pad 1065 has a groove that matches the protrusion. In use, the pad 1065 can move along the protrusion in the Y-axis direction.

[0055] This solution allows for precise adjustment of the push plate base plate 101 in the width direction (Y-axis) by adjusting the different areas of the connecting rod 1066 to be confined within the notch 1064. This meets the high-precision alignment requirements of different magazines or carriers for the push position and is especially suitable for rapid adaptation when switching between multiple magazine models.

[0056] like Figure 1 and Figure 3 As shown, in one specific embodiment, the push plate base plate 101 has at least two mounting holes 1014 spaced apart along its length direction, and the pad plate 1065 can change the relative position of the push plate base plate 101 and the base 1061 by connecting with different mounting holes 1014.

[0057] In this design, the push plate base plate 101 has at least two mounting holes 1014 spaced apart along its length (X-axis). These mounting holes 1014 can be U-shaped holes or elongated slots, and are used to provide different mounting and positioning points. Additionally, the upper surface of the pad plate 1065 has connecting holes corresponding to the positions of the mounting holes 1014, and these connecting holes can be through holes. During assembly, fasteners 1067, such as bolts or screws, pass through the mounting holes 1014 and the connecting holes to fix the pad plate 1065 to the push plate base plate 101.

[0058] It is worth noting that, in terms of adjustment, the connecting holes of the pad 1065 can be aligned with the mounting holes 1014 at different positions on the pusher plate 101. By selecting different mounting holes 1014 for connection, the position of the pusher plate 101 relative to the base 1061 along its length (X-axis) can be adjusted. Then, the fasteners 1067 are tightened using nuts or studs to rigidly connect the pad 1065 to the pusher plate 101, fixing the adjusted position. In other words, this solution does not rely on complex sliding mechanisms or precision components; simply connecting the pad 1065 to the mounting holes 1014 at different positions on the pusher plate 101 allows for convenient adjustment of the relative position of the pusher plate 101 along the X-axis. This solution is suitable for scenarios requiring rapid adaptation to different magazine widths or pusher plate distances, effectively improving equipment debugging efficiency.

[0059] like Figure 1 and Figure 4 As shown, in one specific embodiment, the pusher mechanism 100 further includes a support assembly 107, which includes a fixed seat 1071 and an adjusting seat 1072. The first end of the adjusting seat 1072 is connected to the base 1061, and the second end is connected to the fixed seat 1071. The adjusting seat 1072 has a mounting hole 1073 extending along the thickness direction of the pusher base plate 101. The fixing member on the fixed seat 1071 changes the distance between the pusher base plate 101 and the fixed seat 1071 by connecting to different positions of the mounting hole 1073.

[0060] In this design, the pusher mechanism 100 also includes a support assembly 107, which includes a fixed base 1071 and an adjusting base 1072. The first end of the adjusting base 1072 is connected to the base 1061, and the second end is connected to the fixed base 1071. The main body of the adjusting base 1072 is provided with a mounting hole 1073 extending along the thickness direction (Z-axis direction) of the pusher base plate 101. The mounting hole 1073 can be an elongated slot or a U-shaped hole. A fixing member is provided on the fixed base 1071. The fixing member passes through the mounting hole 1073 of the adjusting base 1072 and is connected to the pusher base plate 101.

[0061] This solution changes the vertical distance between the fixed base 1071 and the adjusting base 1072 by installing the fixing component at different positions (i.e., at different heights within the mounting hole 1073) of the adjusting base 1072. This, in turn, adjusts the distance between the push plate base plate 101 and the fixed base 1071, achieving position adjustment of the push plate base plate 101 in the Z-axis direction. In other words, by changing the position of the fixing component within the mounting hole 1073 of the adjusting base 1072, this solution can precisely adjust the height (Z-axis direction) of the push plate base plate 101 to accommodate magazines or carriers of different heights, ensuring that the push rod assembly 102 is aligned with the magazine in the height direction, thus meeting the accuracy requirements for vertical position during the pushing process.

[0062] In one specific implementation, a clearance portion 1074 is provided at the first end of the adjusting seat 1072. An angle adjusting member 1075 is fixed to the adjusting seat 1072 via a connecting shaft 1076 at the clearance portion 1074. The angle adjusting member 1075 is connected to the base 1061 and is used to adjust the pitch angle of the pusher mechanism 100. The clearance portion 1074 provides rotational space for angle adjustment.

[0063] In this design, the first end of the adjusting seat 1072 of the pusher mechanism 100 is provided with a clearance portion 1074. An angle adjusting member 1075 is fixedly installed in the clearance portion 1074 via a connecting shaft 1076, and the angle adjusting member 1075 is connected to the base 1061. In addition, the pusher mechanism 100 also includes a locking assembly adapted to the angle adjusting member 1075, which is used to fix the relative position of the adjusting seat 1072 and the base 1061 after the angle adjustment is completed.

[0064] During the adjustment process, manually or with tools, rotate the adjusting seat 1072 to tilt the push plate base plate 101 and the push rod assembly 102 together until the push rod head 1021 is parallel to the contact surface of the clip carrier. After the adjustment is in place, fix the adjusting seat 1072 with the locking assembly (such as tightening screws through the fixing holes of the adjusting seat 1072 and the base 1061) to prevent the angle from shifting during operation.

[0065] This solution utilizes the hinged design between the connecting shaft 1076 and the angle adjustment component 1075 to enable flexible rotation of the pusher mechanism 100 in the Ry axis direction. This allows for precise adjustment of the tilt angle of the pusher head 1021, ensuring it is parallel to the wafer contact surface and preventing push jamming or wafer tilting, thus improving the stability and accuracy of wafer removal. Furthermore, this angle adjustment function, along with X-axis, Y-axis, and Z-axis adjustments, forms a four-dimensional adjustment system, enabling precise positioning of the pusher mechanism 100 with full degrees of freedom in space. This meets the stringent requirements for pusher posture in high-precision scenarios such as chip mounting, further enhancing the automation level and production yield of the equipment.

[0066] like Figure 5As shown, in one specific embodiment, the push plate base plate 101 also has a second guide rail 1041 arranged parallel to the first guide rail 1011. A second slider is provided in the second guide rail 1041, and a mounting base plate 1042 is fixedly connected above the second slider. The first conveying assembly is arranged on the mounting base plate 1042. On the side of the push plate base plate 101 away from the push rod assembly 102, there is a second conveying assembly 104. The second conveying assembly 104 includes two spaced-apart rotating wheels 1043 and a conveyor belt 1044 sleeved on the rotating wheels 1043. The first side of the conveyor belt 1032 is connected to the push rod assembly 102, and the second side of the conveyor belt 1032 is fixedly connected to the second side of the conveyor belt 1044 through a second pressure block 1045. The first side of the conveyor belt 1044 is fixedly connected to the mounting base plate 1042 through a third pressure block 1046. The driving device 105 is connected to the rotating wheels 1043, thereby driving the conveyor belt 1032 to move.

[0067] In this design, the push plate base plate 101 also has a second guide rail 1041 arranged parallel to the first guide rail 1011. A second slider is installed inside the second guide rail 1041, and a mounting base plate 1042 is fixedly connected above the second slider. The first conveying assembly 103 is installed above the mounting base plate 1042. In addition, this design also has a second conveying assembly 104 on the push plate base plate 101 on the side of the mounting base plate 1042 away from the push rod assembly 102. The second conveying assembly 104 includes two spaced-apart rotating wheels 1043 and a conveyor belt 1044 sleeved on the rotating wheels 1043. The conveyor belt 1044 is parallel to the conveyor belt 1032 of the first conveying assembly 103. The first side of the conveyor belt 1032 is connected to the push rod assembly 102 via the first pressure block 1033. The second side of the conveyor belt 1032 is fixedly connected to the second side of the conveyor belt 1044 via the second pressure block 1045. The first side of the conveyor belt 1044 is fixedly connected to the mounting base plate 1042 via the third pressure block 1046. Furthermore, to improve the stability of the movement of the second pressure block 1045, a third guide rail 1047 is provided on the upper surface of the mounting base plate 1042. A third slider is provided in the third guide rail 1047, and the third slider is fixedly connected to the second pressure block 1045.

[0068] It is worth noting that, in the above scheme, the first side of the conveyor belt 1032 refers to the side closer to the push rod assembly 102, and the second side refers to the side farther away from the push rod assembly 102. The first side of the conveyor belt 1044 refers to the side closer to the conveyor belt 1032, and the second side refers to the side farther away from the conveyor belt 1032.

[0069] During operation, the motor is connected to the wheel 1043 in the second transmission assembly 104 via a coupling, driving the conveyor belt 1044 of the second transmission assembly 104 to move, and in turn driving the conveyor belt 1032 in the first transmission assembly 103 to move. In this solution, while the conveyor belt 1032 moves a preset distance along the first direction and the first pressure block 1033 moves a preset distance along the second direction, the mounting base plate 1042 also drives the first pressure block 1033 to move a preset distance along the second direction (the first direction and the second direction are two opposite directions along the X-axis). Therefore, under the premise of the same number of motor rotations, the moving distance of the push rod assembly 102 can reach twice that of the solution with only the first transmission assembly 103 and the first guide rail 1011. In other words, this solution reduces the overall length of the mechanism by about half when achieving the same stroke, significantly improving space utilization.
