Description

Technical Field

[0001] This utility model relates to the field of printed circuit board processing equipment technology, and in particular to a printed circuit board feeding machine. Background Technology

[0002] In the manufacturing process of printed circuit boards (PCBs), the board loading stage typically requires a PCB unloading machine. Currently, these unloading machines generally use suction nozzles to pick up the PCBs. To accommodate PCBs of different sizes and improve equipment versatility, some unloading machines are equipped with multiple small-diameter suction nozzles. However, since incoming PCBs often contain dust, debris, and other foreign matter, these small-diameter suction nozzles risk clogging during operation, thus affecting loading stability and equipment operating efficiency. Utility Model Content

[0003] The technical problem solved by this utility model is to provide a stable printed circuit board feeding machine.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a printed circuit board placement machine, including a frame, an XZ two-axis moving platform, a vacuum suction device, and an air blowing pipe, wherein the XZ two-axis moving platform is disposed on the frame; the vacuum suction device is connected to the output end of the XZ two-axis moving platform, and the bottom of the vacuum suction device is provided with multiple suction nozzles; the air blowing pipe is mounted on the vacuum suction device through a bracket, the air blowing pipe is rotatable relative to the bracket, and the air blowing pipe has multiple air blowing holes distributed along the axial direction, the air blowing holes facing downwards from the suction nozzles.

[0005] In one embodiment, a locking member is further provided on the bracket, the locking member contacting the air tube to lock the air tube to the bracket.

[0006] In one embodiment, the locking member includes a connected screw and a handle. The bracket is provided with a through hole for the air tube to pass through and a screw hole communicating with the through hole. The screw hole is threadedly connected to the screw, and the end of the screw away from the handle abuts against the air tube.

[0007] In one embodiment, the handle is perpendicular to the screw.

[0008] In one embodiment, the air tube is located in front of the suction device.

[0009] In one embodiment, the frame is further provided with a lifting drive assembly and a lifting platform. The lifting platform is vertically movable relative to the frame. The lifting drive assembly is connected to the lifting platform to drive the lifting platform to move up and down. The lifting platform is located below the moving path of the vacuum suction device.

[0010] The beneficial effects of this utility model are as follows: By adding a rotatable air blowing pipe to a traditional vacuum suction device, and setting multiple air blowing holes axially towards the lower part of the suction nozzle on the air blowing pipe, dust, slag, and other foreign objects on the surface of the circuit board can be pre-blown away through the air blowing holes before suctioning the circuit board. This effectively avoids the problem of blockage caused by the small-diameter suction nozzle adsorbing foreign objects, and significantly improves the stability and reliability of the feeding process. At the same time, the rotatable design of the air blowing pipe allows for flexible adjustment of the blowing angle according to the actual working conditions, enhancing the adaptability of the device to circuit boards of different sizes and incoming material conditions. The axial distribution of multiple air blowing holes ensures that the blowing range can cover the working area of ​​each suction nozzle, achieving comprehensive pre-cleaning of the suction position. This reduces the frequency of equipment downtime for maintenance due to suction nozzle blockage, ensures continuous operation of the production line, improves overall operating efficiency, and the structure is simple and compact, easy to modify and implement on existing equipment, and is both practical and economical.

[0033] Example 1

[0034] Please refer to Figures 1 to 5 Embodiment 1 of this utility model is as follows: A printed circuit board placement machine includes a frame 1, an XZ two-axis moving platform 2, a vacuum suction device 3, and an air blowing pipe 4. The XZ two-axis moving platform 2 is mounted on the frame 1. The vacuum suction device 3 is connected to the output end of the XZ two-axis moving platform 2. The bottom of the vacuum suction device 3 is provided with multiple suction nozzles. The vacuum suction device 3 is connected to an external vacuum pump, which causes the suction nozzles to produce a vacuum suction effect. The air blowing pipe 4 is directly or indirectly mounted on the vacuum suction device 3 through a bracket 6. The air blowing pipe 4 is rotatable relative to the bracket 6. The air blowing pipe 4 has multiple air blowing holes 41 distributed along the axial direction. The air blowing holes 41 face downwards from the suction nozzles. The air blowing pipe 4 is connected to an external air source, and the air blowing holes 41 blow out the air driven by the air source.

[0035] The XZ two-axis moving platform 2 is a two-dimensional positioning motion system composed of two mutually perpendicular linear motion axes, the X-axis (horizontal direction) and the Z-axis (vertical direction). Through stacked or cross-connected mechanical structures, it forms a precisely controllable motion module in the vertical plane. This platform, driven by the linkage of the X and Z axes, enables the load connected to its output end (such as a vacuum suction device 3) to achieve precise point-to-point movement, trajectory interpolation, or reciprocating motion in both the horizontal and vertical directions, thereby completing specific tasks in three-dimensional space (such as horizontal position adjustment and vertical lifting and loading / unloading actions).

[0036] The printed circuit board placement machine also includes a locking member 5 mounted on the support 6. The locking member 5 contacts the air blowing pipe 4 to lock the air blowing pipe 4 to the support 6. By adding the locking member 5 to contact and lock the air blowing pipe 4, the air blowing pipe 4 can be stably positioned after the angle adjustment is completed. This effectively prevents the angle of the air blowing pipe 4 from shifting due to equipment vibration or accidental contact, ensuring that the air blowing hole 41 is always accurately aligned with the area to be cleaned below the suction nozzle, maintaining the continuous stability of the air blowing cleaning effect, and thus improving the overall reliability of the equipment operation.

[0037] The locking component 5 includes a connected screw 51 and a handle 52. The bracket 6 has a through hole 61 for the air tube 4 to pass through and a screw hole 62 communicating with the through hole 61. The screw hole 62 is threadedly connected to the screw 51, and the end of the screw 51 away from the handle 52 abuts against the air tube 4. The locking component 5, composed of the screw 51 and the handle 52, provides a stable and reliable locking force through the threaded connection, and has a simple and compact structure. The handle 52 allows the operator to manually tighten or loosen the air tube without the need for tools, greatly simplifying the adjustment of the air tube 4 angle and improving the convenience and efficiency of equipment debugging and maintenance. In this embodiment, the handle 52 is perpendicular to the screw 51, allowing the operator to apply less force when tightening, which conforms to ergonomic design and makes operation more convenient and comfortable.

[0038] Optionally, the air blowing pipe 4 is located on the front side of the suction device, so that when the XZ two-axis moving platform 2 drives the vacuum suction device 3 to move towards the circuit board, the air blowing pipe 4 reaches the top of the circuit board before the suction nozzle to perform the air blowing cleaning action, realizing a continuous operation process of blowing first and then suction, without the need for additional reciprocating actions or pauses, thus improving the overall efficiency and smoothness of the loading operation.

[0039] The frame 1 is also equipped with a lifting drive assembly 7 and a lifting platform 8. The lifting platform 8 is adjustable in height relative to the frame 1. The lifting drive assembly 7 is connected to the lifting platform 8 to drive it to move up and down. The lifting platform 8 is located below the moving path of the vacuum suction device 3. By setting the lifting drive assembly 7 and the lifting platform 8 on the frame 1, the position of the lifting platform 8 can be automatically adjusted according to the stacking height of the incoming circuit boards, ensuring that the circuit boards are always within the effective working range of the vacuum suction device 3. This enhances the adaptability of the equipment to different incoming material heights and stacking methods. Simultaneously, it enables continuous automatic feeding of stacked circuit boards, reducing the frequency of manual intervention in adjusting material positions and further improving the automation level and continuous operation stability of the production line. In this embodiment, the lifting drive assembly 7 includes a motor, a reducer, and a lead screw connected in sequence, and the lifting platform 8 is threadedly connected to the lead screw.

[0040] The above are merely optional embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
