DETAILED DESCRIPTION

[0034] In order to make the objectives, technical solutions, and superiorities of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described below in connection with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort belong to the scope of protection of the present application.

[0035] As Figures 1 to 3As shown, the feeding module of the embodiment comprises a feeding base 91 and a pushing assembly 92. The pushing assembly 92 comprises a pushing mounting structure 921, a box gripper structure 922 and a pushing rod structure 923. The pushing mounting structure 921 is mounted on the feeding base 91, and the box gripper structure 922 is movably mounted on the pushing mounting structure 921. The pushing rod structure 923 comprises a pushing rod base 9231, a pushing rod mounting seat 9232, a driving member 9233, a first spring 9234 and a pushing rod 9235. The pushing rod base 9231 is mounted on the box gripper structure 922. The driving member 9233 and the pushing rod mounting seat 9232 are both slidably arranged on the pushing rod base 9231. The pushing rod 9235 is mounted on the pushing rod mounting seat 9232. The driving member 9233 is connected with the pushing rod mounting seat 9232 through the first spring 9234. When the pushing rod 9235 encounters a resistance greater than a predetermined resistance, the driving member 9233 moves relative to the pushing rod mounting seat 9232.

[0036] In the technical scheme of the embodiment, when feeding, the driving member 9233 drives the pushing rod mounting seat 9232 to move, and the pushing rod mounting seat 9232 drives the pushing rod 9235 to move. When the pushing rod 9235 pushes the carrier plate and encounters a resistance greater than a predetermined resistance, the driving member 9233 continues to move forward. Since the driving member 9233 and the pushing rod mounting seat 9232 are connected through the first spring 9234, the first spring 9234 is stretched and cannot continue to move forward, thereby preventing the carrier plate from being damaged. The technical scheme of the embodiment effectively solves the problem of carrier plate damage caused by the die bonder being stuck when pushing the carrier plate in the prior art.

[0037] As shown in the drawings, Figure 3 In the technical scheme of the embodiment, the feeding module further comprises a power assembly 93. The power assembly 93 is connected with the driving member 9233 to drive the driving member 9233 to slide on the pushing rod base 9231. The power assembly 93 can be a hydraulic structure, an electric push rod structure or a pneumatic structure. In the embodiment, the power assembly 93 is a pneumatic structure. The above structure is compact and easy to operate.

[0038] As shown in the drawings, Figures 1 to 3 In the technical scheme of the embodiment, the feeding module further comprises an alarm assembly. The alarm assembly comprises a sensing sheet, a photoelectric sensor and an alarm. The sensing sheet and the photoelectric sensor are respectively mounted on the driving member 9233 and the pushing rod mounting seat 9232. When the driving member 9233 moves relative to the pushing rod mounting seat 9232 by a predetermined distance, the sensing sheet corresponds to the photoelectric sensor to make the alarm give an alarm. The setting of the alarm assembly ensures that the operator can discover and handle the fault in time, thereby greatly improving the safety of the feeding module 90.

[0039] As shown in the drawings, Figure 3As shown, in this embodiment, the driving component 9233 is a driving plate with a groove, and the push rod mounting seat 9232 is at least partially located within the groove. This structure provides excellent limiting for the push rod mounting seat 9232. The groove design is simple, convenient, and cost-effective.

[0040] like Figure 3 As shown, in this embodiment, the push rod structure 923 further includes a second spring 9236 and a stop plate 9237. The second spring 9236 is mounted on the push rod mounting base 9232, and the stop plate 9237 is rotatably mounted on the push rod mounting base 9232. The push rod 9235 is located on the side of the stop plate 9237 away from the second spring 9236. The side of the stop plate 9237 facing the second spring 9236 has a slot. The second spring 9236 has a stop position for inserting into the slot and a clearance position for disengaging from the slot. When the stop plate 9237 is in the clearance position, the push rod 9235 can be removed from the push rod mounting base 9232. The arrangement of the second spring 9236 and the stop plate 9237 ensures that repairs and remediation can be performed in case of jamming or other situations. The stop plate can be a stop block or a stop rod.

[0041] like Figures 1 to 3 As shown, in this embodiment, a vertical slide rail structure is also provided between the material box gripper structure 922 and the material pusher mounting frame structure 921, so that the material box gripper structure 922 can move vertically. The above structure facilitates the vertical movement of the material box gripper structure 922. The vertical movement in this embodiment includes two aspects: first, the material box gripper structure 922 moves upward after gripping the material box; second, the material box gripper structure 922 gradually rises as the carrier plate is pushed out layer by layer.

[0042] like Figure 1 and Figure 2 As shown in the technical solution of this embodiment, the feeding module further includes a material box conveying assembly 94. The material box conveying assembly 94 includes a width adjustment structure, which includes feeding baffles, feeding slide rails, and feeding screws disposed on both sides of the feeding base 91. The two ends of the feeding screw are respectively connected to the feeding baffles on both sides of the feeding base 91, and the feeding slide rails pass through the feeding baffles. The structure of the feeding screw ensures that the baffles on both sides move simultaneously, thus ensuring the symmetry of the material box from both the angle of force and the angle of position.

[0043] like Figure 1 and Figure 2 As shown, in this embodiment, the material box conveying assembly 94 further includes a conveyor belt structure, which is mounted on the loading base 91. This structure enables automatic control of the material box conveying process.

[0044] like Figure 1 and Figure 2As shown, in this embodiment, the empty material box placement section is located on the feeding base 91 and above the material box conveying assembly 94. This structure improves efficiency and saves space.

[0045] like Figures 4 to 12 As shown, this application also provides a die bonder. The die bonder includes a feeding module, which is the feeding module described above.

[0046] like Figures 4 to 8 As shown, the die bonder includes: a mounting frame module 10, a dispensing module 20, a waiting module 30, a die bonder module 40, a loading module 50, and a conveying module 60. The dispensing module 20 is mounted on the mounting frame module 10. The waiting module 30 is mounted on the mounting frame module 10. The die bonder module 40 is mounted on the mounting frame module 10 and includes a die bonder head structure 41 and a robotic arm structure 42. The robotic arm is mounted on the mounting frame module 10, and the die bonder head structure 41 is mounted on the robotic arm structure 42. The robotic arm structure 42 can drive the die bonder head structure 41 to move. The loading module 50 is mounted on the mounting frame module 10. The conveying module 60 is mounted on the mounting frame module 10 and can drive the carrier board to move between the dispensing module 20, the waiting module 30, the die bonder module 40, and the loading module 50. The loading module 90 is located on the side of the dispensing module 20 away from the die bonder module 40.

[0047] In this embodiment, the carrier, conveyed by the conveying module 60, sequentially passes through the dispensing module 20 for dispensing, and then enters the waiting module 30 for inspection, such as checking whether the dispensing is qualified. After passing through the waiting module 30, it enters the die-bonding module 40 under the drive of the conveying module 60. After completing the die-bonding work, it passes through the unloading module 50. This assembly line operation completes dispensing, inspection, and die-bonding, greatly improving the working efficiency of the die-bonding machine. This embodiment effectively solves the problems of low integration and low working efficiency of existing die-bonding machines. The carrier includes the carrier body and the objects on the carrier body.

[0048] like Figure 4 and Figure 5As shown, in this embodiment, the mounting frame module 10 includes a base assembly 11, a guide rail assembly 12, and a flow channel assembly 13. The guide rail assembly 12 is fixed on the base assembly 11, and the flow channel assembly 13 is movably mounted on the guide rail assembly 12, supporting the carrier plate on the flow channel assembly 13. The flow channel assembly 13 moves on the guide rail assembly 12, accommodating carrier plates of different sizes and models, thus enhancing the versatility of the die bonder. It should be noted that the extension direction of the guide rail assembly 12 is perpendicular to the extension direction of the flow channel assembly 13. This embodiment also includes a guide structure, which is fixed on the mounting frame module 10. The flow channel assembly 13 and the guide structure cooperate to ensure smoother movement of the flow channel assembly 13 when adjusting the width of the flow channel. Multiple guide rail assemblies are included, each adapted to the limiting support frame structure 131 and located at the bottom of the limiting support frame structure 131.

[0049] like Figure 5 As shown, in this embodiment, the flow channel assembly 13 includes a limiting support frame structure 131, which includes a first limiting support plate and a second limiting support plate. The first and second limiting support plates have an adjustable predetermined distance to form a flow channel. Both the first and second limiting support plates extend along the moving direction of the carrier plate. The limiting structure includes the first and second limiting support plates. By adjusting the distance between the first and second limiting support plates, it can accommodate carrier plates of different sizes. This structure has low manufacturing costs and is easy to operate. It should be noted that the guide structure consists of multiple guide rods, through which the first and second limiting support plates pass. The extending direction of each guide rod is parallel to the guide rail assembly 12.

[0050] like Figure 5As shown, in the technical scheme of the embodiment, the first limiting support plate comprises a first limiting plate and a first support plate, the first support plate is located on the side of the first limiting plate close to the second limiting support plate, the upper surface of the first support plate is lower than the upper surface of the first limiting plate to form a first stepped surface, the second limiting support plate comprises a second limiting plate and a second support plate, the second support plate is located on the side of the second limiting plate close to the first limiting support plate, the upper surface of the second support plate is lower than the upper surface of the second limiting plate to form a second stepped surface. The cooperation of the first stepped surface and the second stepped surface can realize the support of the carrier plate, so that the upward supporting force of the carrier plate can be realized, and the stress of the conveying module 60 is reduced. The cooperation of the side surface of the first limiting plate and the side surface of the second limiting plate avoids the carrier plate from separating from the flow channel, so that the carrier plate can better move along the predetermined track. The first limiting support plate and the second limiting support plate of the embodiment are simple in structure and easy to operate. It should be noted that the heights of the first stepped surface and the second stepped surface are the same. The first limiting plate comprises a first limiting plate segment, a second limiting plate segment, a third limiting plate segment and a fourth limiting plate segment, the second limiting plate comprises a fifth limiting plate segment, a sixth limiting plate segment, a seventh limiting plate segment and an eighth limiting plate segment. The first support plate comprises a first support plate segment, a second support plate segment, a third support plate segment and a fourth support plate segment, the second support plate comprises a fifth support plate segment, a sixth support plate segment, a seventh support plate segment and an eighth support plate segment. The first limiting plate segment and the first support plate segment are connected together, the second limiting plate segment and the second support plate segment are connected together, the third limiting plate segment and the third support plate segment are connected together, and so on. The lengths of the first limiting plate segment, the first support plate segment, the fifth limiting plate segment and the fifth support plate segment are the same, and they are correspondingly arranged with the glue dispensing module 20; the lengths of the second limiting plate segment, the second support plate segment, the sixth limiting plate segment and the sixth support plate segment are the same, and they are correspondingly arranged with the material feeding module 30; the lengths of the third limiting plate segment, the third support plate segment, the seventh limiting plate segment and the seventh support plate segment are the same, and they are correspondingly arranged with the die bonding module 40; the lengths of the fourth limiting plate segment, the fourth support plate segment, the eighth limiting plate segment and the eighth support plate segment are the same, and they are correspondingly arranged with the material discharging module 50.

[0051] As shown in Figure 5 and Figure 7 As shown, in the technical scheme of the embodiment, the flow channel assembly 13 further comprises a flow channel driving structure 132, the flow channel driving structure 132 is connected with the limiting support frame structure 131 to drive the limiting support frame structure 131 to change the predetermined distance of the flow channel. The above-mentioned structure is convenient to operate.

[0052] As shown in Figure 5 and Figure 7As shown, in this embodiment, the flow channel drive structure 132 includes a first motor, a lead screw, and two connecting parts. The output shaft of the first motor is connected to the lead screw, and both ends of the lead screw are threadedly connected to the two connecting parts. A first limiting support plate and a second limiting support plate are fixedly connected to the two connecting parts. The flow channel drive structure 132 described above has a lower processing cost and applies a more balanced force. Specifically, both ends of the lead screw connected to the two connecting parts have the same thread, which makes the force exerted by the lead screw on the two connecting parts more balanced, enabling the two connecting parts to move synchronously and simultaneously. The two connecting parts respectively drive the first limiting support plate and the second limiting support plate to move synchronously and simultaneously. When the size of the carrier plate changes and the width of the flow channel needs to be adjusted, the first limiting plate and the second limiting plate on both sides of the carrier plate simultaneously and synchronously move towards the carrier plate, thus improving the working accuracy in terms of both force and moving distance.

[0053] like Figure 4 and Figure 6 As shown in the technical solution of this embodiment, the die bonder further includes a first pressure plate structure 70 and a first top plate structure 80. The first pressure plate structure 70 is fixedly connected to the limiting support frame, and the first top plate structure 80 is disposed on the mounting frame module 10. The first pressure plate structure 70 and the first top plate structure 80 are correspondingly disposed, and the first pressure plate structure 70 cooperates with the dispensing module 20. By fixing the carrier plate with the first pressure plate structure 70 and the first top plate structure 80, the carrier plate can be limited and fixed in multiple directions, thus further ensuring the accuracy of the carrier plate during operation. The second pressure plate structure and the second top plate structure are disposed at corresponding positions in the die bonder module 40.

[0054] like Figure 4 , Figure 6 and Figure 8 As shown, in this embodiment, the first top plate structure 80 includes a second motor, a first cam, a first transmission part, and a first top plate. The second motor is connected to the first cam to drive the first cam to rotate. The first cam engages with the bottom of the first transmission part, and the top of the first transmission part is fixedly connected to the first top plate. The first top plate and the first pressure plate structure 70 have a pressing position that is close to each other or a disengaging position that is far apart from each other. The structure of the first cam ensures that the force applied by the first top plate when pressing against the load plate is relatively gentle. Similarly, when the first top plate moves from the pressing position to the disengaging position, it also moves away smoothly.

[0055] like Figure 7As shown in the technical solution of this embodiment, the first transmission part includes a first mating block and a first connecting plate. The bottom surface of the first mating block has an arc-shaped surface that mates with the first cam. The arc-shaped surface of the bottom surface of the first mating block makes the contact area between the first mating block and the first cam relatively large, thus ensuring a more stable fit between them. Furthermore, the arc-shaped structure of the first mating block also ensures that the first transmission part moves at the desired speed.

[0056] In this embodiment, the first top plate structure 80 further includes a first elastic element. One end of the first elastic element is connected to the base assembly 11, and the second end of the first elastic element is connected to the first top plate structure 80 so that the first transmission part contacts the first cam. The first elastic element ensures that the first cam and the first mating block can have a mutual pressing force under the action of external force, that is, the first transmission part always maintains a downward force under the action of spring force. The first elastic element includes two springs, which are symmetrically located on both sides of the first cam to make the force between the first transmission part and the first cam balanced and uniform. Specifically, the two springs are in a stretched state.

[0057] like Figure 7 As shown, in the technical solution of this embodiment, the first pressure plate structure 70 includes a first pressure plate 71 and a second elastic member 72. The second elastic member 72 is disposed on the first pressure plate 71. When the first top plate and the first pressure plate structure 70 are in a pressing position, the first top plate and the second elastic member 72 jointly press against the carrier plate. The provision of the second elastic member 72 ensures that when the carrier plate is pressed together by the first top plate structure 80 and the first pressure plate structure 70, the carrier plate is not rigidly pressed, and the carrier plate has a buffering force. This structure ensures that the carrier plate is not easily damaged.

[0058] like Figure 7 As shown, in this embodiment, the second elastic element 72 includes a first spring sheet, which is fixed to the first pressure plate 71. The above structure is compact and easy to use.

[0059] like Figure 7 As shown, in this embodiment, the first spring includes a first connecting plate and a first pressure foot. The first end of the first pressure foot is connected to the side of the first connecting plate. The first pressure plate 71 has a hollow hole. The first connecting plate is connected to the surface of the first pressure plate 71 away from the first top plate structure 80. The second end of the first pressure foot passes through the hollow hole. The above structure is compact and has low processing cost. Specifically, the first connecting plate and the first pressure foot are integrally formed.

[0060] like Figure 7As shown, in this embodiment, the angle between the plane of the first connecting plate and the plane of the first pressure foot is greater than 90° and less than 180°. The second end of the first pressure foot has an outward flange, which is connected to the first pressure foot through an arc-shaped connecting part. The angle between the plane of the first connecting plate and the plane of the first pressure foot is greater than 90° and less than 180°, which ensures the ease of use of the first spring piece. For example, when the first spring piece moves downward, the increased angle between the plane of the first connecting plate and the plane of the first pressure foot can achieve the force and elastic force on the carrier plate. The second spring piece includes a second connecting plate and two second pressure feet. The two second pressure feet are arranged opposite to each other on both sides of the second connecting plate. The first connecting plate and the second connecting plate have the same structure, and the first pressure feet have the same structure. When there are multiple hollow holes, adjacent hollow holes have connecting bridges. The second connecting plate is connected on the connecting bridges. Both ends of the second connecting plate have second pressure feet, so that both sides of the second connecting plate can form elastic pressure on the carrier plate. The first spring piece is used at the position of the hollow holes at both ends, and the second spring piece is used at the position of the connecting bridge between two adjacent hollow holes.

[0061] In the technical solution of this embodiment, the unloading module 50 includes an anti-static push rod, which pushes the carrier plate away from the flow channel assembly and also prevents static electricity from damaging the carrier plate.

[0062] like Figure 4 As shown, in this embodiment, the conveying module 60 includes a third motor, a conveyor belt, driven wheels, and a carrier plate clamping structure. The third motor and driven wheels are respectively disposed at both ends of the mounting module. The conveyor belt cooperates with the third motor and driven wheels, and the carrier plate clamping structure is disposed on the conveyor belt. The conveyor belt can ensure a large span for the conveying module 60. In this embodiment, multiple carrier plate clamping structures can be used, which improves efficiency. For example, the dispensing module 20 and the die bonding module 40 can work simultaneously, moving different carrier plates at the same time. The second top plate structure includes a fourth motor, a second cam, a second transmission part, and a second top plate.

[0063] In this embodiment, the carrier plate clamping structure includes a clamping mounting base, a fixed clamping part, a movable clamping part, and a clamping drive part. The clamping mounting base is mounted on a conveyor belt, the fixed clamping part is fixedly mounted on the clamping mounting base, and the clamping drive part is mounted on the clamping mounting base. The clamping drive part is connected to the movable clamping part to drive the movable clamping part closer to the fixed clamping part in a clamping position, or to drive the movable clamping part away from the fixed clamping part in a released position. The part of the carrier plate clamping structure that mates with the carrier plate is made of PEEK (polyetheretherketone) material. The carrier plate clamping structure described above is easy to operate. The movable clamping part can be connected to a pneumatic cylinder, a hydraulic cylinder, or an electric actuator.

[0064] like Figures 8 to 12As shown, in this embodiment, the die-bonding head structure 41 includes a die-bonding head 411 and a die-bonding head connector 412. The die-bonding head connector 412 is fixed to the robotic arm structure 42, and the die-bonding head 411 is magnetically mounted on the die-bonding head connector 412. The robotic arm structure 42 can drive the die-bonding head 411 to work, making the die-bonding work more precise and highly automated. The die-bonding head 411 and the die-bonding head connector 412 are connected by magnetic force, which greatly improves the assembly and disassembly efficiency. The die-bonding head 411 and the die-bonding head connector 412 are magnetically attracted and fixed, reducing the steps of installing and removing screws.

[0065] In this embodiment, the die bonder 411 includes a die bonder body and a die bonder mounting base. The die bonder mounting base has a mounting hole, and the die bonder body is installed in the mounting hole. The structure of the die bonder body and the die bonder mounting base facilitates maintenance and allows for the installation of mating structures, such as a ferromagnetic material in the die bonder mounting base.

[0066] like Figure 9 As shown, in this embodiment, the die bonder mounting base includes a ferromagnetic body, a first mounting section, a limiting section, and a second mounting section. The limiting section is located between the first and second mounting sections. The ferromagnetic body is located on the side of the first mounting section away from the limiting section, and the outer diameter of the limiting section is larger than the outer diameter of the first mounting section. The ferromagnetic body facilitates the mating connection between the die bonder body and the die bonder mounting base. The limiting section ensures that the bottom edge of the die bonder mounting base abuts against the upper surface of the limiting section. The limiting section is a circular plate, and the upper part of the first mounting section is frustoconical, while the lower part is cylindrical. Figure 12 As shown. The second mounting section is fixed to the die bonder body by a pin. The side wall of the second mounting end has a pin through hole, and the side wall of the die bonder body has a groove corresponding to the pin hole. The pin passes through the pin through hole and enters the groove.

[0067] like Figure 11 As shown, in this embodiment, the die bonder connector 412 includes a base body and a connecting tube. The connecting tube is disposed on the side wall of the base body and can communicate with the die bonder body. The above structure is compact and easy to connect. The negative pressure adsorbed by the connecting tube is between 0.1 kPa and 0.8 kPa.

[0068] like Figure 11 and Figure 12 As shown, in this embodiment, the mounting hole extends from the end of the second mounting section away from the limiting section to the first mounting section. The sidewall of the first mounting section has a connecting hole that connects the mounting hole and the connecting tube. The above structure is compact and easy to install, and the die bonding head body is a hollow tube.

[0069] like Figure 11 and Figure 12As shown, in this embodiment, the die bond connector 412 further includes a magnet, and the connector includes a receiving space, within which the magnet is disposed. The above structure is compact and offers high assembly / disassembly efficiency. In this embodiment, the magnet is a permanent magnet, and the connection between the die bond 411 and the die bond mounting base is achieved through the attraction of the two magnets. When disassembling, the die bond 411 is removed from the die bond mounting base by external force. Alternatively, the magnet can be an electromagnet; when disassembly is required, the electromagnet is de-energized, and the die bond 411 is removed under the influence of gravity or external force.

[0070] like Figure 11 and Figure 12 As shown, in this embodiment, the ferromagnetic material and the first mounting section are located within the accommodating space, and the first mounting section has a mutually cooperating limiting part with the wall of the accommodating space. This results in a high fitting accuracy between the die bonder 411 and the die bonder connector 412. The first mounting section has a frustum that mates with the frustum section, further improving the fitting accuracy between the connector and the die bonder 411, and reducing the processing cost of the above structure. The accommodating space, from the side away from the die bonder 411 to the side closer to the die bonder 411, sequentially includes a first cylindrical section, a second cylindrical section, a frustum section, and a cylindrical section, with the magnet mounted inside the connector. The side wall of the first mounting base has a foolproof surface, and the side wall of the connector has a plane that mates with the foolproof surface. A fixing hole is located on the side wall of the connector corresponding to the foolproof surface, and a pin is used to fix the first mounting end to the connector.

[0071] like Figure 11 and Figure 12 As shown, in this embodiment, the die bonding module 40 further includes a die bonding head removal structure and a die bonding head storage structure 43, both of which are mounted on the mounting frame module 10. This structure further improves the automation level of the die bonding machine. When the die bonding head 411 needs to be replaced, it is removed by the die bonding head removal structure, and then the die bonding head 411 in the die bonding head storage structure is automatically installed using magnetic force. The die bonding head removal structure can be a standalone structure or part of a system, for example, a connecting tube blowing out positive pressure gas, which removes the die bonding head 411 using the force of the positive pressure gas.

[0072] It should be noted that the die bonder in this embodiment has multiple cameras. For example, a camera (or a video camera if needed) is installed at the position of the material receiving module 30 to detect the dispensing result. Both the dispensing module 20 and the die bonder module are equipped with cameras to detect the dispensing and die bonding processes. This embodiment also includes a movable camera that can be moved to the required detection position as needed.
