Description

Technical Field

[0001] The utility model relates to the technical field of flexible circuit board production and processing equipment, in particular to a feeding detection device for material tape patches. Background Art

[0002] By embedding the circuit design on a bendable thin plastic sheet, a flexible circuit board is obtained. The flexible circuit board has the characteristics of high wiring density, light weight, thin thickness and good bendability.

[0003] Processing equipment is installed along the conveyor to perform operations such as patching and testing on flexible circuit boards to complete the patching process. During the production process, the patching line is long, the production speed is not constant, the material belt starts and stops intermittently on the line, and the tension of the flexible material belt is unstable. The material belt is prone to deviation and bending, which is not conducive to the patching process and makes successful patching difficult.

[0004] To address the above issues, a Chinese patent application, application number CN202410537271.4, titled "A Double-Sided SMT Device," discloses two sets of execution sections between a loading tray and a receiving tray. The strip passes through the execution sections and is processed by processing equipment along the sides. The strip power system is comprised of a strip conveying power mechanism and a strip auxiliary power mechanism located between the execution sections and at the corners between the execution sections and the trays. The auxiliary power mechanism includes an adjustment roller and a leveling power assembly. By moving the adjustment roller, the interaction force between the strip and the adjustment roller is maintained, keeping the strip flat and unbending.

[0005] However, refer to the attached Figure 5 In the existing technology, although the problem of material strip bending has been solved, due to the large number of equipment components, loose layout, large overall equipment volume, and long execution section assembly line length, it is not conducive to improving processing efficiency, and there is still room for improvement in the material strip movement processing efficiency.

[0006] Based on the problems in the prior art, the utility model provides a feeding detection device for tape patch. Utility Model Content

[0007] The purpose of the utility model is to provide a feeding detection device for material strip patching, so as to solve the technical problems in the prior art of large equipment volume, loose component layout and low material strip moving processing efficiency.

[0008] The technical solution of the utility model is: a feeding detection device for material strip patch, comprising a side feeding platform correspondingly installed on the feeding area of ​​the first execution section and a horizontal feeding platform correspondingly installed on the second execution section; the top feeding end surface of the side feeding platform is used for spreading and feeding materials, and a side detection unit is provided on the bottom back side surface of the side feeding platform; the top feeding end surface of the horizontal feeding platform is used for spreading and feeding materials, and a horizontal detection unit is provided on the side where the bottom back side surface of the horizontal feeding platform is located;

[0009] The detection head end faces of the side detection unit and the horizontal material picking detection unit are respectively parallel to the corresponding back side surfaces of the bottom, and partial areas of the corresponding back side surfaces are respectively located within the detection areas corresponding to the side detection unit and the horizontal material picking detection unit.

[0010] Preferably, in the first execution section, the first grabbing end is driven by a three-dimensional linear module to move back and forth between the side feeding platform and the loading station of the first execution section to load the patch;

[0011] In the second execution section, the second grabbing end is driven by a three-dimensional linear module to move back and forth between the horizontal feeding platform and the loading station of the second execution section to load the patch;

[0012] During the movement and material grabbing and material transfer process, the grabbing end surface of the first grabbing end head remains parallel to the material spreading end surface of the horizontal feeding platform; during the movement and material grabbing and material transfer process, the grabbing end surface of the second grabbing end head remains parallel to the material spreading end surface of the horizontal feeding platform.

[0013] Preferably, the side of the material belt where material separation occurs is set as the material picking end, and the side of the material belt entering the side feeding platform or the horizontal feeding platform is set as the flattening end. The material belt at the material picking end extends out of the side feeding platform or the horizontal feeding platform by at least two material lengths, and the first grabbing end or the second grabbing end grabs materials at intervals on the material belt.

[0014] Preferably, the first execution section and the second execution section are respectively provided with a detection and cutting mechanism, and the detection and cutting mechanism is used to detect whether the patch on the material tape is qualified and cut off the unqualified patch section from the material tape.

[0015] Preferably, the side detection unit and the horizontal detection unit include a detection terminal and a lighting light source respectively.

[0016] Compared with the prior art, the advantages of the present invention are:

[0017] (1) The present invention adjusts the relative position relationship between the detection unit and the feeding platform so that the feeding end is within the detection area of ​​the detection unit, so that the material grabbing end can be directly detected during the material picking process. Compared with moving the material to the detection area for detection after picking up the material, this can save material picking detection time and improve processing efficiency.

[0018] (2) During the movement and material grabbing and transferring process, the grabbing end face of the grabbing head remains parallel to the material spreading end face of the feeding platform, without the need to rotate and adjust the posture, saving time and improving processing efficiency.

[0026] The following is a further detailed description of the present invention in conjunction with specific embodiments:

[0027] like Figure 1 As shown, a feeding detection device for material strip patching is applied to a double-sided patch machine system for flexible circuit board processing. In the system, two sets of feeding mechanisms, rolling mechanisms, and patch mechanisms are arranged on the production line of the first execution section and the second execution section perpendicular to each other to patch the material strip 9.

[0028] The feeding detection device includes a lateral feeding platform 3 installed corresponding to the feeding area of ​​the first execution section 7 and a horizontal feeding platform 4 installed corresponding to the second execution section 8; the lateral feeding platform 3 and the horizontal feeding platform 4 have the same components and operating principles, and the horizontal feeding platform 4 is rotated 90 degrees and placed sideways to obtain the lateral feeding platform 3.

[0029] The top feeding end face of the side feeding platform 3 is used for spreading and feeding materials, and a side detection unit 1 is provided on the bottom back side of the side feeding platform 3; the top feeding end face of the horizontal feeding platform 4 is used for spreading and feeding materials, and a horizontal detection unit 2 is provided on the bottom back side of the horizontal feeding platform 4;

[0030] The side detection unit 1 and the horizontal detection unit 2 respectively include a detection head 10 and a lighting source 11. Figure 2 .

[0031] Refer to the attached Figure 3 The detection head end face of the side-standing detection unit 1 is parallel to the corresponding bottom back side, and part of the corresponding back side is within the detection area of ​​the side-standing detection unit 1. Figure 4 The detection head end surface of the horizontal detection unit 2 is parallel to the corresponding bottom back side surface, and a partial area of ​​the corresponding back side surface is within the detection area of ​​the horizontal detection unit 2.

[0032] In the first execution section 7, the first grabbing end head 5 is driven by a three-dimensional linear module to move back and forth between the side feeding platform 3 and the loading station of the first execution section to load and patch. During the movement and grabbing and transferring process, the grabbing end face of the first grabbing end head 5 remains parallel to the material spreading end face of the side feeding platform 3.

[0033] In the second execution section 8, the second grabbing end head 6 is driven by a three-dimensional linear module to move back and forth between the horizontal feeding platform 4 and the loading station of the second execution section to load the patch; during the movement and grabbing and transferring process, the grabbing end face of the second grabbing end head 6 remains parallel to the spreading end face of the horizontal feeding platform 4.

[0034] Prior art (see Appendix Figure 5 ) The feeding platform, the loading station of the execution section, and the detection unit are not in the same straight line, and the grabbing end needs to rotate and adjust the direction after taking the material before loading. In the loading process, after the grabbing end takes the material and leaves the feeding platform, it first moves to the detection area of ​​the detection unit, pauses for inspection, and then moves to the loading station to load the material.

[0035] In this embodiment, through the relative relationship between the layout components, the material picking ends of the two groups of feeding platforms are directly set in the detection area of ​​the detection end, and the material grabbing ends are directly inspected during the material picking process. Since the feeding end of the feeding platform and the loading station of the execution section are maintained in the same straight line extension direction, there is no need to rotate and adjust the angle direction of the material grabbing end.

[0036] Therefore, compared with the prior art, this embodiment can save the time of stopping for inspection and the time of rotating to adjust the angle direction of the grabbing end, thereby improving efficiency. In addition, the structure between the equipment components is more compact, reducing the size of the equipment.

[0037] The side where the material belt 9 enters the side feeding platform 3 or the horizontal feeding platform 4 is set as the flattened end, and the material belt 9 at the material picking end extends out of the side feeding platform 3 or the horizontal feeding platform 4 by at least two material lengths, and the first grabbing end 5 or the second grabbing end 6 picks up materials at intervals on the material belt 9 to achieve smooth material picking.

[0038] In addition, a detection and cutting mechanism 12 is respectively provided at the unloading end of the first execution section 7 and the second execution section 8 to detect whether the patches on the material strip 9 are qualified and to cut off the unqualified patch sections from the material strip 9.

[0039] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with this technology to understand the content of the present invention and implement it accordingly, and they are not intended to limit the scope of protection of the present invention. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes that fall within the meaning and scope of the equivalent elements of the claims are included in the present invention.
