Description

Technical Field

[0001] This utility model relates to the field of die bonding equipment technology, and in particular to a double-layer feeding assembly and die bonding equipment. Background Technology

[0002] Die bonding, also known as die bonding, involves using an adhesive to bond a wafer to a designated area on a support, creating a thermal or electrical path to facilitate subsequent wire bonding. It is mainly used in lead frame plates of various gold wire ultrasonic welding equipment, as well as various nozzles, ejector pins, dispensing heads, ceramic nozzles, through-hole needles, motors, carbon brushes, encoders, drive belts, and various spare parts, instruments, etc. of various chip mounting equipment and automated robotic arms.

[0003] The PCB board feeding technology of die bonding equipment directly restricts production efficiency and cost control. Existing feeding methods are mainly divided into two categories: single-piece gripping, which uses a vacuum suction gripper to precisely pick up a single PCB board, which is then transferred to the next station by a horizontal pushing mechanism after passing through a transfer platform. While this achieves high-precision positioning, it only processes one piece at a time, resulting in a slow production cycle. Furthermore, the integration of multiple modules such as vision positioning and gripping leads to complex equipment structure, increased floor space, and increased manufacturing costs. Multi-piece stacking, which stacks PCB boards in a material box and uses lifting or side-pushing mechanisms for batch transport, improves processing efficiency but is prone to problems such as board misalignment and adhesion. It is also only suitable for single-specification boards, requiring machine downtime during type changeovers, making it difficult to meet diverse production needs. To integrate the advantages of both methods, some solutions attempt to combine high-precision single-piece feeding with efficient multi-piece transport. However, the parallel operation of two systems leads to increased equipment size and significantly increased complexity of the mechanical transmission and control systems, resulting in a surge in equipment costs and a corresponding increase in failure rate. With the trend of small-batch, multi-variety production, there is an urgent need to develop compact and integrated feeding components to balance accuracy, efficiency and cost, and promote the technological upgrade of die bonding equipment.

[0043] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0044] The illustrations provided in this embodiment are only schematic representations of the basic concept of this utility model. Therefore, the drawings only show the components related to this utility model and are not drawn according to the actual number, shape and size of the components. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0045] In die bonding equipment, the PCB board feeding technology directly restricts production efficiency and cost control. Existing feeding methods are mainly divided into two categories: single-piece gripping, which uses a vacuum suction gripper to precisely pick up a single PCB board, which is then transferred to the next station by a horizontal pushing mechanism after passing through a transfer platform. While this achieves high-precision positioning, it only processes one piece at a time, resulting in a slow production cycle. Furthermore, the integration of multiple modules such as vision positioning and gripping leads to a complex equipment structure, increased floor space, and higher manufacturing costs. Multi-piece stacking, which stacks PCB boards in a material box and uses lifting or side-pushing mechanisms for batch transport, improves processing efficiency but is prone to problems such as board misalignment and adhesion. It is also only suitable for single-specification boards, requiring machine downtime for changes in board type, making it difficult to meet diverse production needs. To integrate the advantages of both methods, some solutions attempt to combine high-precision single-piece feeding with efficient multi-piece transport. However, the parallel operation of two systems leads to increased equipment size and significantly increased complexity of the mechanical transmission and control systems, resulting in soaring equipment costs and a higher failure rate. With the trend towards small-batch, multi-variety production, there is an urgent need to develop compact, integrated feeding components to balance accuracy, efficiency, and cost, and to drive the technological upgrade of die bonding equipment. To address this, this utility model proposes a double-layer feeding component, comprising: an upper material box rack 10, horizontally arranged and used to hold materials to be transferred; a lower material box rack 20, arranged parallel to the upper material box rack 10 and used to hold boxes of materials to be transferred, each box containing multiple stacked materials; a transfer platform 30, connected to the outlet of the upper material box rack 10; and an adsorption transfer rack 40 disposed above the transfer platform 30, the adsorption transfer rack 40 being horizontally movable and moving closer to or further away from the outlet of the upper material box rack 10. An adsorption transfer rack 40 is assembled to transfer a single material above the outlet of the upper material box rack 10 to the transfer platform 30; a material box lifting rack 50 is located at the outlet of the lower material box rack 20, and is assembled to vertically lift the material box at the outlet of the lower material box rack 20 to the transfer platform 30. When the material box is vertically lifted, the transfer platform 30 and the material box lifting rack 50 avoid each other; a pusher rack 60 is located beside the outlet of the upper material box rack 10, and is used to horizontally push a single material on the transfer platform 30 or the material in the material box to the next workstation.

[0046] See Figure 1 and Figure 2 In one embodiment, the material to be transferred can be transferred to the upper material box rack 10 by a robotic arm, and the material on the upper material box rack 10 can be adsorbed onto the transfer platform 30 by the adsorption transfer rack 40. By activating the pusher rack 60, the material on the transfer platform 30 can be horizontally pushed to the next work station.

[0047] In another embodiment, after the materials to be transferred are stacked in the material box, the material box is horizontally transferred to the outlet position by the lower material box rack 20, and the material box at the outlet position of the lower material box rack 20 is vertically transferred to the side position of the pusher rack 60 by the material box lifting frame 50. When the two transportation methods are switched before the material box lifting frame 50 lifts the material box, the vertical path of the transfer platform 30 and the material box lifting frame 50 avoids each other, so that the material box can be transferred to the side position of the pusher rack 60. By starting the pusher rack 60, the single material in the material box is horizontally pushed to the next station.

[0048] In one embodiment, the pusher 60 moves horizontally and is perpendicular to the horizontal movement direction of the adsorption transfer frame 40. When the material is transferred to the side of the push path of the pusher 60, the pusher 60 moves horizontally, thus pushing the material horizontally to the next station perpendicular to the transfer direction. Therefore, the longitudinal and horizontal space of the entire equipment can be fully utilized, reducing the space occupied by the transfer equipment and reducing the cost of the entire equipment.

[0049] In one embodiment, the transfer platform 30 is disposed on the sliding avoidance unit, and the sliding direction of the transfer platform 30 is horizontal and parallel to the moving direction of the adsorption transfer frame 40.

[0050] In one specific embodiment, the transfer platform 30 is a rectangular plate with slots for positioning and engaging individual materials to ensure accurate positioning. The sliding avoidance unit includes a linear guide rail 31, which is parallel to the moving direction of the upper material box frame 10. The transfer platform 30 is slidably mounted on the linear guide rail 31, and a pushing cylinder 32 is provided on the side of the linear guide rail 31. The pushing cylinder drives the transfer platform 30 to slide on the linear guide rail 31 to avoid obstacles.

[0051] In one embodiment, see Figure 3 The upper material box rack 10 includes an upper mounting plate 11. The upper mounting plate 11 has a horizontal surface and a material box stop block 12 at one end. Multiple sets of acetal steel pads 13 are provided on the upper surface of the upper mounting plate 11. The multiple sets of acetal steel pads 13 are arranged in parallel at intervals and along the length direction of the upper mounting plate 11. A material box width adjustment rod 14 is provided on the side of the upper mounting plate 11. The material box width adjustment rod 14 is arranged in parallel with the acetal steel pads 13 and the distance between it and one side of the upper mounting plate 11 is adjustable.

[0052] In the above embodiment, the material box width adjustment rod 14 is arranged parallel to the acetal pad strip 13 and the distance between it and one side of the upper mounting plate 11 is adjustable. By adjusting the distance between the material box width adjustment rod 14 and one side of the upper mounting plate 11, it can be adapted to various types of material conveying.

[0053] In one embodiment, see Figure 4 and Figure 5 The lower material box rack 20 includes a lower feeding base plate 21. The lower feeding base plate 21 is horizontal and has multiple sets of parallel and spaced rolling synchronous belts 22 on its upper surface. The rolling synchronous belts 22 are arranged along the length of the lower feeding base plate 21 and are driven to rotate by a rolling motor 23. A material box baffle 24 is provided on the side of the lower feeding base plate 21. The material box baffle 24 is parallel to the rolling synchronous belts 22 and the distance between the baffle 24 and the side of the lower feeding base plate 21 is adjustable.

[0054] Similarly, in the above embodiments, the material box baffle 24 is parallel to the rolling synchronous belt 22 and the distance between it and the side of the lower feed plate 21 is adjustable. By adjusting the distance between the material box baffle 24 and the side of the lower feed plate 21, it can be adapted to the conveying of various types of material boxes.

[0055] In one embodiment, see Figure 10 To receive the material box at the discharge end of the lower bottom plate 21, a mounting base plate 51 is provided below the material box lifting frame 50. A slide rail 52 is provided on the mounting base plate 51. The slide rail 52 is horizontal and parallel to the lower material box frame 20. A slider 53 is provided on the slide rail 52. A horizontal lead screw 54 is rotatably provided on the mounting base plate 51. The horizontal lead screw 54 is parallel to the slide rail 52 and cooperates with the nut on the slider 53. The horizontal lead screw 54 is driven by a horizontal motor 55.

[0056] In the above embodiment, by activating the horizontal motor 55, the material box lifting frame 50 and the slider 53 slide on the slide rail 52, thereby bringing the material box lifting frame 50 closer to the outlet of the lower material box frame 20 to receive the material box.

[0057] In one embodiment, see Figure 8 and Figure 9 To enable gripping and vertical lifting of the material box, the material box lifting frame 50 includes a vertical frame 56, which is fixed to the slider 53. A lower gripper 57 of the material box is vertically slidably mounted on the vertical frame 56. A vertical screw 561 is rotatably mounted on the vertical frame 56, and the vertical screw 561 cooperates with a vertical nut mounted on the lower gripper 57 of the material box. An upper gripper 58 of the material box is vertically slidably mounted on the vertical frame 56. A vertical cylinder 562 is mounted on the vertical frame 56, and the vertical cylinder 562 drives the upper gripper 58 of the material box to move closer to or away from the lower gripper 57 of the material box.

[0058] In one embodiment, the vertical cylinder 562 can also form a vertical sliding engagement with the vertical frame 56 via a slide rail. When the upper gripper 58 of the material box grips the upper part of the material box, the lower gripper 57 of the material box slides vertically upward. When the entire material box is dragged upward, the vertical cylinder 562 can also move along with it, transferring the material box to the position in front of the outlet of the pusher 60.

[0059] In one embodiment, see Figure 11 and Figure 12 The pusher frame 60 includes a pusher mounting base 61, a pusher upright plate 62 is provided on the pusher mounting base 61, a pusher adjusting seat 63 is horizontally provided on the upper end of the pusher upright plate 62, a pusher mounting base plate 64 is provided on the pusher adjusting seat 63, a linear track 641 is provided on the pusher mounting base plate 64, a pusher 65 is slidably provided on the linear track 641, the linear track 641 is horizontal and perpendicular to the horizontal movement direction of the adsorption transfer frame 40, a pusher driving belt 642 is provided on the pusher mounting base plate 64, the pusher driving belt 642 is arranged parallel to the pusher 65 and driven by a pusher motor 643, and the pusher 65 is used to perform horizontal pushing of materials.

[0060] In the above embodiment, a guide roller is provided at the front end of the push rod mounting base plate 64, and the push rod 65 is located between the guide rollers. The guide rollers can be used to guide the push rod 65 horizontally to ensure the accuracy of the push rod 65 in pushing the material.

[0061] Furthermore, the adsorption transfer rack 40 includes an adsorption rack 41 composed of multiple adsorption heads. The adsorption rack 41 is mounted on a vertical drive mechanism, which drives the adsorption rack 41 to move vertically. The vertical drive mechanism is mounted on a horizontal drive mechanism, which drives the adsorption rack 41 to move horizontally and to move closer to or further away from the outlet of the upper material box rack 10.

[0062] This utility model also proposes a die bonding device, which includes a double-layer feeding assembly. Through the parallel double-layer layout of the upper feed box 10 and the lower feed box 20, the horizontal projected area of ​​the device is reduced compared to traditional dual-mode feeding devices while achieving the same function. The number of mechanical structural components is simplified, directly reducing the manufacturing cost of the device. This effectively solves the problems of large size and high cost of existing multi-mode feeding devices. Since this die bonding device adopts all the technical solutions of all the above embodiments, it possesses at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated further here.
