Description

Technical Field

[0001] The invention relates to a full-automatic shooting machine, in particular to a multi-head high-efficiency assembly line shooting machine. Background Art

[0002] The target shooting machine uses a camera as its "eyes" and can automatically and quickly and accurately lock onto the material to be processed through computer software or single-chip microcomputer control, thereby forming a cross target shape on the device display and finally automatically drilling a hole.

[0003] The existing fully automatic shooting machines are generally independent devices with only a single shooting mechanism, that is, the shooting machine only has a set of shooting spindles and corresponding presser feet for drilling holes. In order to improve the automation of the shooting machine, it is usually equipped with corresponding loading and unloading mechanisms. When working, the material to be processed is grabbed by the loading mechanism and placed on the workbench of the equipment, and then the material is processed by the automatic shooting mechanism. After the processing is completed, the processed material is taken out by the unloading mechanism, and this process is repeated one by one.

[0004] For example, we have retrieved an automatic shooting machine disclosed by announcement number CN 207266388 U, a fully automatic PCB integrated shooting machine disclosed by announcement number CN209050138 U, a high-precision PCB shooting machine disclosed by announcement number CN 212992689 U, and a high-precision CNC shooting machine for circuit board production disclosed by announcement number CN 214604781 U, etc.

[0005] Since this type of fully automatic target shooting has only a single target shooting mechanism, it can only process a single circuit board per unit time, and the processing of each circuit board requires a complete set of loading, processing and unloading actions, resulting in its production efficiency can only be maintained at a certain level, and cannot be further improved, and cannot match the production efficiency of its corresponding upstream and downstream production equipment. Therefore, this type of fully automatic target shooting can usually only be used as an independent device, and it cannot be incorporated into the production line, let alone achieve efficient online assembly line production.

[0006] To this end, the relevant technical personnel in this field have made further improvements to the fully automatic shooting machine. For example, a flexible circuit board shooting machine disclosed in the announcement number CN 107454748 A includes a frame and a conveyor belt arranged on the frame, and a plurality of shooting devices are arranged above the conveyor belt. In its specific embodiment, it is further disclosed that there are eight groups of shooting devices 3, which are symmetrically arranged on both sides of the conveyor belt 2. The eight groups of shooting devices 3 can punch holes at the same time, and the punching efficiency is higher. The multiple groups of shooting devices 3 are respectively fixed on multiple mounting platforms 5, and the multiple mounting platforms 5 are arranged on the frame 1 and can be horizontally moved along the X-axis and the Y-axis on the frame 1. By moving the position of the mounting platform 5, the position between the two groups of shooting machines relative to each other and the two groups of shooting machines adjacent to the same side can be adjusted. However, since each of the target shooting devices 3 is a complete assembly, the eight groups of target shooting devices 3 are actually simply arranged and accumulated eight individual target shooting devices. Although there is some improvement in processing efficiency, the mechanism is cumbersome, and the position between the two groups of target shooting machines and the two adjacent groups of target shooting machines on the same side cannot be further reduced, and it cannot adapt to the efficient processing of more sophisticated circuit boards.

[0007] In order to further improve the processing efficiency of the automatic target shooting machine, it is necessary to reasonably optimize and improve the existing fully automatic target shooting machine, especially the pressure foot assembly and punching assembly of the automatic target shooting machine, so as to achieve more efficient and refined production, and realize online assembly line production. Summary of the invention

[0008] Based on the above-mentioned deficiencies of the prior art, the present invention provides a multi-head high-efficiency assembly line type targeting machine. The present invention can simultaneously perform collaborative processing on multiple targeting points on a circuit board within a unit time, thereby greatly improving production efficiency. At the same time, it can also flexibly meet more complex and sophisticated processing requirements.

[0013] Preferably, a processing platform and a material picking and placing mechanism for grabbing materials are provided on the material processing plane.

[0014] Preferably, a material conveying mechanism and a material positioning mechanism are provided on the material processing plane.

[0015] The beneficial effects of the present invention are as follows: the multi-head high-efficiency assembly line type target shooting machine of the present invention can simultaneously perform collaborative processing on multiple target shooting points on the circuit board within a unit time, thereby greatly improving the production efficiency, and at the same time can flexibly meet more complex and more refined processing requirements, and can not only realize the independent and efficient production of a single device, but also can match the processing speed of the upstream and downstream equipment, thereby realizing online assembly line production.

[0016] The high-efficiency multi-head cooperative presser foot assembly of the present invention sets four retractable presser feet and an image collector on the same set of first substrate and first transverse guide rail, and then is driven by respective first transverse feeding mechanisms and first transverse slide plates. This can not only greatly reduce the volume of the presser foot assembly, making the equipment more compact, but more importantly, it is also conducive to improving the mutual cooperation ability between the various presser feet, and greatly reduces the spacing between adjacent presser feet, making the spacing between adjacent presser feet smaller, and can provide support for the simultaneous online processing of multiple holes with smaller spacing on the circuit board, thereby improving the processing accuracy of the equipment.
