Description

Technical Field

[0001] This utility model relates to the field of electronic device mounting equipment technology, specifically to a long auxiliary material mounting machine. Background Technology

[0002] A surface mount device (SMT) is a piece of equipment that, in a production line, is placed after a dispensing machine or screen printer. It works by moving a mounting head to accurately place surface mount components onto a PCB or FPC board.

[0003] During the mounting process of long flat auxiliary materials, because these materials are typically not rigid, they often deform along their length. When using high resolution to position the entire product, this can lead to poor matching, and consequently, low recognition rate and accuracy. Furthermore, due to the thickness of the auxiliary material and the camera's triangular imaging principle, this thickness causes image distortion and introduces positioning errors when the material is positioned at different points within the camera's field of view. The closer the positioning point is to the edge of the field of view, the greater the positioning deviation. When attempting to image the entire long auxiliary material with a single camera, both ends often enter the edge of the camera's field of view, further increasing the positioning error and affecting the accuracy of the positioning.

[0004] Therefore, a new technical solution is needed to solve the above-mentioned technical problems. Utility Model Content

Detailed Implementation

[0035] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention. The present invention will be described in detail below with reference to the accompanying drawings.

[0036] This utility model provides a mounting machine for mounting long, flat auxiliary materials. In this embodiment, "longer" refers to auxiliary materials with a length greater than 180mm. Since the auxiliary materials are not rigid materials, they usually bend and deform along their length. During the positioning and recognition process by the vision camera, positioning errors may occur due to deformation and the long length. The mounting machine provided by this utility model, by setting a first recognition component 400 and a second recognition component 500, can accurately identify the auxiliary materials, avoid errors, and ensure accurate positioning.

[0037] Specifically, such as Figure 1-5As shown, this utility model embodiment provides a flat long auxiliary material mounting machine, including a machine base 100 providing a mounting position. A feeder 110 for conveying flat and long workpieces is mounted on the machine base 100. A conveying device 300, a picking device 300, a first identification component 400, and a second identification component 500 are also mounted on the machine base 100. The conveying device 300 is positioned beside the feeder 110 along a predetermined direction. The picking device 300 is used to pick up the workpiece conveyed by the feeder 110. The workpiece is then transferred to the conveying device 300. The picking device 300 includes a three-axis moving module 310 disposed beside the feeder 110 and a suction cup assembly 320 disposed on the three-axis moving module 310 for adsorbing the workpiece. The first identification component 400 is disposed directly above the feeder 110 and includes two first vision cameras 410 distributed along the length direction of the workpiece. The second identification component 500 is disposed directly above the conveying device 300 and includes two second vision cameras 510 distributed along the length direction of the workpiece. In this embodiment, the three-axis moving module 310 includes three linear modules arranged along the X, Y, and Z axes, thereby enabling the suction cup assembly 320 to reciprocate along the X, Y, and Z axes.

[0038] During the mounting process, long auxiliary materials are fed by the feeder 110. The suction cup assembly 320, driven by the three-axis moving module 310, rotates the long auxiliary materials and transfers them onto the conveyor 300. During this process, the two first vision cameras 410 of the first recognition assembly 400 illuminate and recognize the ends of the long auxiliary materials located on the feeder 110. By recognizing the two ends of the auxiliary materials along their length, the auxiliary materials can be accurately positioned. At the same time, the conveyor 300 transports products that are stacked and mounted with the auxiliary materials during the transmission process. The two second vision cameras 510 of the second recognition assembly 500 photograph and recognize the two ends of the product along its length, thereby accurately positioning the product. Since the second vision cameras 510 are set at both ends of the product's length, visual distortion due to its large length can be avoided. When the suction cup assembly 320 transfers and mounts the auxiliary materials onto the product, the mounting process can be completed efficiently.

[0039] In this embodiment, a stripping plate 111 is provided at the output end of the feeder 110. The first identification component 400 is located directly above the stripping plate 111, and two first vision cameras 410 are arranged along the length of the stripping plate 111, respectively at both ends of the stripping plate 111. Specifically, the auxiliary material is attached to the material strip and forms a roll, which is then mounted on the feeder 110. After the material strip passes through the stripping plate 111, the auxiliary material is peeled off on the material strip, making it easier for the suction cup component 320 to pick it up. At this time, the first vision camera 410 corresponds to the stripping plate 111 and is located directly above it, so that the auxiliary material can be identified after it is peeled off from the material strip, thereby positioning the auxiliary material.

[0040] In this embodiment, to more accurately identify the products conveyed by the conveying device 300 and ensure the accuracy of auxiliary material placement, the second identification component 500 is further provided with an upper light source plate 520. The upper light source plate 520 is located below the two second vision cameras 510 and is used to illuminate the products towards the conveying device 300. Two illumination windows 521, corresponding to the two second vision cameras 510, are provided on the upper light source plate 520. The upper light source plate 520 can illuminate the products during identification, preventing visual errors caused by lighting conditions.

[0041] In this embodiment, the conveying device 300 is used to transport products. At the same time, the application of auxiliary materials is also completed on the conveying device 300, and the products after application are conveyed along a predetermined direction. It includes a frame, a drive device 203, a lower light source plate 204, and a conveyor belt 205. The frame 201 is mounted on the machine base 100 along the predetermined direction, and rollers 202 are rotatably connected to both ends. The drive device 203 is driven by any one of the rollers 202. The lower light source plate 204 is mounted on the frame 201 corresponding to the upper light source plate 520. The conveyor belt is sleeved on the two rollers 202 and covers the lower light source plate 204. The conveyor belt 205 is driven by the drive device 203 to perform reciprocating transmission.

[0042] In other words, during the mounting process of the conveyor 300, the lower light source board 204 can illuminate the product from below, thereby providing supplementary lighting to the product and ensuring the accuracy of the positioning process of the second identification component 500.

[0043] During the mounting process, a clamping assembly 210 is also provided on the conveyor 300. The clamping assembly 210 is used to clamp and fix the product, thereby ensuring the accuracy of mounting. The clamping assembly 210 includes two units located on both sides of the conveyor belt 205, which can clamp the two side edges of the product to keep it stable. The clamping assembly 210 includes a clamping cylinder 211, a vertical plate 212, and a clamping plate 213. Figure 3 As shown, the clamping cylinder 211 is fixedly mounted on the frame; one end of the vertical plate 212 is connected to the clamping cylinder 211 in the vertical direction and is driven by the clamping cylinder 211 to move back and forth along the width direction of the conveyor belt 205; the other end of the vertical plate 212 extends vertically and above the conveyor belt 205; one end of the clamping plate 213 is fixedly mounted above the vertical plate 212, and the other end extends horizontally toward the center of the conveyor belt 205.

[0044] In this embodiment, an example of the structure of the suction cup assembly 320 is given, such as... Figure 5 As shown, the suction cup assembly 320 includes a mounting base 321, a rotating shaft 322, and a suction cup motor 323. Specifically, the mounting base 321 is driven to the three-axis moving module 310; the rotating shaft 322 is vertically oriented and rotatably connected to the mounting base 321, and a mounting plate (not shown in the figure) with a suction nozzle is fixedly mounted on the downward-facing end of the rotating shaft 322; the suction cup motor 323 is fixedly mounted on the mounting base 321 and driven to the rotating shaft 322 to drive the rotating shaft 322 to rotate. By driving the rotating shaft 322 to rotate through the suction cup motor 323, the direction of the mounting plate can be adjusted, thereby ensuring more precise placement of auxiliary materials and products.

[0045] In this embodiment, to further improve the mounting accuracy, a third identification component 600 is also provided on the machine 100. The third identification component 600 is located on the travel path of the suction cup assembly 320 and is used to identify the lower surface of the workpiece gripped by the suction cup assembly 320. The third identification component 600 includes a third vision camera 610 with its lens facing upwards. That is to say, during the transfer of auxiliary materials, the third vision camera 610 identifies the auxiliary materials again to detect the state of the lower surface of the auxiliary materials (that is, the mounting surface) to ensure that there are no foreign objects that affect the reliability of the mounting.
