Description

Technical Field

[0001] The utility model relates to the technical field of electronic component processing, in particular to a chip arrangement visual detection device. Background Art

[0002] In the manufacturing of electronic components such as LEDs, MOS tubes, and chips, LED arrays, MOS tube arrays, and chip arrays are often first manufactured on a support frame and then die-molded. Finally, the individual electronic components are cut and cut. The quality of these arrays placed in the mold for die-molding is closely related to whether the arrays are placed correctly. If the arrays are placed upside down or offset, the subsequent die-molding process will be greatly affected. However, the placement of the arrays on the mold net is done manually, and whether the placement is correct is mainly judged by the naked eye. The human eye is easily tired and cannot always see, which can easily lead to missed detections and cannot guarantee the quality of the inspection. Utility Model Content

[0003] Based on this, it is necessary to provide a visual inspection device for the placement of slices that is not easily missed, has high inspection quality, and reduces the workload of workers in order to address the problem of judging the placement position of slices on existing molds.

The multi-axis robot arm can move with the camera module, and then the camera can clearly capture images of the film arrangement on the mold under the action of the auxiliary light source. The captured image can be used by the judgment device to determine whether it is in place. In addition, the clamping and transporting mechanism can efficiently and accurately place the film arrangement on the mold, and can also remove the film arrangement from the mold.

[0020] To facilitate understanding of the present invention, a more comprehensive description of the present invention will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to facilitate a more thorough and comprehensive understanding of the disclosure of the present invention.

[0021] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there can be an intermediate element. When an element is considered to be "connected to" another element, it can be directly connected to the other element or there can be an intermediate element. In addition, the term "and / or" in this article is merely a description of the association relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are intended only to describe specific embodiments. For example, “inner,” “outer,” “left,” “right,” and similar expressions are intended only for illustrative purposes and are not intended to limit this invention.

[0023] Please refer to Figures 1 to 5 , is a schematic diagram of a film arrangement visual inspection device 100 of the present invention, which includes an adapter frame 20, at least one camera module 30 installed on the adapter frame 20, and at least one clamping and transporting mechanism 40. The camera module 30 includes a camera 31 and an auxiliary light source 32. The auxiliary light source 32 can improve the lighting environment for image acquisition, thereby improving the clarity of image acquisition. The clamping and transporting mechanism 40 includes a beam 41 connected to the adapter frame 20, two connecting rods 42 extending downward from the beam 41, a base plate 43 connected to the bottom of the two connecting rods 42, at least one clamping cylinder 44 installed on the top surface of the base plate 43, and a clamping arm 45 connected to the clamping cylinder 44. The bottom end of the clamping arm 45 is lower than the bottom surface of the base plate 43. Two clamping arms 45 are symmetrically installed on one of the clamping cylinders 44, so that the clamping action can be completed.

[0024] Furthermore, in this embodiment, the number of camera modules 30 and the number of clamping and transporting mechanisms 40 are both two groups, and two groups of camera modules 30 and clamping and transporting mechanisms 40 can improve efficiency.

[0025] Furthermore, there are multiple auxiliary light sources 32, and the multiple auxiliary light sources 32 are arranged around the camera 31, so that a clear visible lighting environment can be formed around the camera 31 to ensure the clarity of image acquisition.

[0026] The camera module 30 further includes a connecting plate 33 connected to the adapter 20, an adjustment plate 34 hingedly connected to the connecting plate 33 and connected to the camera 31, and an adjustment bolt (not shown) mounted on the connecting plate 33. The adjustment plate 34 has an arc-shaped hole 35 through which the adjustment bolt passes. During use, the camera 31 can rotate the adjustment plate 34 to a preset angle and then lock it with the adjustment bolt, allowing the camera to adjust the capture angle as needed, which is very practical.

[0027] Furthermore, a support plate 46 is mounted on the top surface of the base plate 43, and a clamping cylinder 44 is connected to the support plate 46. Two support plates 46 are mounted on the base plate 43, and each base plate 43 has two clamping cylinders 44.

[0028] Furthermore, a threaded sleeve 48 is mounted on the crossbeam 41, and the outer wall of the connecting rod 42 is threadedly connected to the threaded sleeve 48. During use, the connecting rod 42 can be rotated to drive the bottom plate 43 to adjust its height, thereby driving the clamping cylinder 44 to adjust its height. To ensure the adjustable limit effect of the connecting rod 42, a limit ring 49 is installed on the top of the connecting rod 42. In this embodiment, the clamping arm 45 is arranged in an L-shape, so that the clamping cylinder 44 can lift and clamp the tablets, providing support for the bottom of the tablets.
