Description

Technical Field

[0001] This utility model relates to the field of semiconductor manufacturing technology, and in particular to an outer box photography device. Background Technology

[0002] The semiconductor industry is mainly divided into complex processes of chip design, chip manufacturing, and chip packaging and testing, involving close cooperation between upstream and downstream industries. Every semiconductor manufacturer faces a large number of incoming and outgoing shipments, and the inspection of the appearance of the packaging boxes during the incoming and outgoing shipment process is crucial. This is related to whether there is any loss and the division of responsibility for the loss. In addition to visual inspection, it is also very important to take photos of the packaging boxes to preserve traceable evidence.

[0003] In this field, manual visual inspection and manual photography are usually the main methods of preservation, but this method is very inefficient and the problems of missed inspections, missed photos, and wrong photos are very common. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an outer box photography device.

[0005] To achieve the aforementioned objectives, the technical solution adopted by this utility model includes:

[0006] This utility model provides an outer box photography device, which includes a main structure, a transparent carrier plate and multiple cameras. The main structure has a accommodating chamber. The transparent carrier plate is disposed in the accommodating chamber, dividing the accommodating chamber into a first cavity and a second cavity, and the transparent carrier plate is used to support the packaging box.

[0007] The multiple cameras are divided into a first part, a second part, and a third part, with the normal of the transparent carrier plate as the height direction. The first part is located at the top of the first cavity, the second part is located on the side of the first cavity, and the third part is located at the bottom of the second cavity. The shooting direction of the cameras is all pointing towards the bearing position of the packaging box.

[0008] Based on the above technical solution, compared with the prior art, the beneficial effects of this utility model include at least the following:

[0009] The outer box photography device provided by this utility model uses a transparent carrier plate to support the packaging box, and uses multiple sets of shooting cameras distributed at the top, middle and bottom of the outer box photography device to take multi-angle shots of the packaging box in a full-encirclement manner. It can realize one-time full-view shooting of the appearance of the packaging box, avoiding the problems of missed inspection, missed shooting or wrong shooting faced by manual shooting, significantly improving the efficiency of appearance inspection of incoming and outgoing goods, and reducing labor costs.

[0010] The above description is only an overview of the technical solution of this utility model. In order to enable those skilled in the art to better understand the technical means of this application and to implement it in accordance with the contents of the specification, the preferred embodiments of this utility model are described below with reference to the accompanying drawings.

[0015] In view of the shortcomings of the prior art, the inventor of this case, through long-term research and extensive practice, has come up with the technical solution of this utility model. The following will further explain the technical solution, its implementation process, and its principles.

[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0017] Moreover, relational terms such as “first” and “second” are used merely to distinguish one component or method step from another that has the same name, without necessarily requiring or implying any such actual relationship or order between these components or method steps.

[0018] The inventors of this utility model discovered during practice that taking photos of the outer packaging of box 8 upon entry and exit is necessary for data traceability and to avoid unresolved anomalies. To prevent missed or incorrect photos, it is also usually necessary to scan the label code on the outer packaging of box 8 for identification and to link the images of each side of the carton.

[0019] The system automatically identifies the condition of the outer packaging; if the outer packaging is damaged, the system will sound an alarm and halt customs. Figure 1 and Figure 2As shown, an embodiment of this utility model provides an outer box photography device, which includes a main structure 1, a transparent carrier plate 2, and multiple cameras 3. The main structure 1 has a receiving chamber; the transparent carrier plate 2 is disposed in the receiving chamber, dividing the receiving chamber into a first cavity and a second cavity, and the transparent carrier plate 2 is used to support the packaging box 8; the multiple cameras 3 are divided into a first part 31, a second part 32, and a third part 33, with the normal direction of the transparent carrier plate 2 as the height direction. The first part 31 is disposed at the top of the first cavity, the second part 32 is disposed on the side of the first cavity, and the third part 33 is disposed at the bottom of the second cavity; the shooting direction of the cameras 3 is all pointing towards the supporting position of the packaging box 8.

[0020] In the specific implementation examples provided by this utility model, the main structure 1 can be Figure 1 and Figure 2 The frame-plate structure shown consists of a main frame 11 forming the skeleton, with some side panels 12 fixed to the frame surface for covering, forming a box structure. The interior of the box structure is the accommodating chamber. A transparent carrier plate 2 is horizontally arranged in this accommodating chamber, and the packaging box 8 is placed on this transparent carrier plate 2 during appearance inspection and photography. At the top and bottom of the accommodating chamber, multiple cameras 3 (i.e., the first part 31 and the third part 33 mentioned above) are arranged around the packaging box 8. One or more cameras 3 are also arranged in the middle (approximately at the same level as the packaging box 8) to take pictures of the packaging box 8 from multiple angles above, below, and horizontally simultaneously (or in a certain order, usually all angles can be taken during one appearance inspection and photography process). The obtained images are used for archiving and can also be further input into an image recognition model for program judgment of appearance acceptance, replacing or assisting manual visual inspection.

[0021] Furthermore, since the label of the packaging box 8 is usually affixed to the side, the horizontally positioned camera 3 (i.e., the second part 32) can also perform the task of scanning and recognizing the label code of the packaging box 8. It only requires setting a corresponding computer program to extract the barcode from the image. This is not necessarily related to the device structure provided by this utility model. The realization of the function of this utility model depends on the structural design, not on the software program.

[0022] Regarding the specific structural configuration, in some implementation schemes, such as Figure 2 As shown, the accommodating chamber is cubic in shape. The first part 31 is located at the four corners of the top surface of the accommodating chamber, the third part 33 is located at the four corners of the bottom surface of the accommodating chamber, and the second part 32 is located on the side wall of the middle part of the accommodating chamber.

[0023] Still with Figure 1 and Figure 2 For example, the camera 3 includes eight cameras 3 set at the eight corners of the cube and one camera 3 set on the side facing the packaging box 8, for a total of nine cameras 3. When taking pictures to inspect the appearance of the packaging box 8, nine images can be obtained at the same time. These images are then input into the MES production management system (hereinafter referred to as the MES system, Manufacturing Execution System), where they can be uniformly stored and used to determine whether the appearance quality of the packaging box 8 is qualified.

[0024] Furthermore, to ensure clear imaging, in some embodiments, the outer box imaging device may also include a top light source 4 disposed on the top surface and a bottom light source 5 disposed on the bottom surface. For example, a linear light source can be disposed on the top surface to illuminate downwards, and a linear light source can be disposed on the bottom surface to illuminate upwards. Of course, the arrangement of the light sources is not limited to this; any light source arrangement that can achieve comprehensive illumination of the packaging box 8 from all sides to ensure image quality is acceptable.

[0025] Since packaging boxes 8 from different sources or with different destinations often have different sizes or different label placements, using a positioning structure to restrict the position and orientation of the packaging boxes 8 is not suitable for the actual application needs of semiconductor manufacturers. Therefore, the preferred embodiment of this utility model adopts a transparent carrier plate 2 with a positioning structure without any protrusions or grooves on the entire surface. That is, in some embodiments, the bearing surface of the transparent carrier plate 2 is a flat and smooth plane.

[0026] As an example, the transparent carrier plate 2 can be a single piece of tempered glass or plexiglass, etc., and its bearing surface no longer has a structure that prevents the packaging box 8 from moving freely. Instead, the operator can move the packaging box 8 at will to place it at the best shooting angle.

[0027] To facilitate the handling of the packaging box 8, in some embodiments, the receiving chamber is provided with an opening located on the front of the receiving chamber.

[0028] Furthermore, referring to the arrangement of drawer slides, the preferred embodiment of this utility model also includes a transparent carrier plate 2 that can be pulled out from the opening. In some embodiments, the transparent carrier plate 2 is slidably connected to the main structure 1, and the sliding direction is from the inside of the accommodating chamber to the opening. The width of the transparent carrier plate 2 is smaller than the width of the opening, so that at least part of the transparent carrier plate 2 can slide outside the opening.

[0029] More specifically, in some embodiments, the main structure 1 is provided with a slide rail, the sliding direction of which is the direction from the inside of the accommodating chamber to the opening, and the transparent carrier plate 2 is fixed on the slide rail.

[0030] The above-mentioned setup allows the transparent carrier plate 2 to be partially or completely pulled out when it is necessary to place or remove the packaging box 8, making it easier for the operator to move or place the packaging box 8 and reducing the operator's labor intensity.

[0031] In some implementations, the opening is located on the front of the first cavity, and the second cavity is enclosed on all four sides.

[0032] Regarding other structures, in some embodiments, the outer box photographing device may further include an industrial control computer 6, with the camera 3, top light source 4, and bottom light source 5 all electrically connected to the industrial control computer 6. The industrial control computer 6 can connect to the MES system via the Internet or a local area network, upload images or image analysis results, receive instructions from the MES system, and perform actions such as tracking and locking of the packaging box 8.

[0033] In some implementations, the outer casing photographing device may further include a display 7, which is fixed on the side wall of the main structure 1 and electrically connected to the industrial control computer 6.

[0034] As a practical application example of the above embodiments, the lens angle of the camera 3 can be adjusted so that the captured image covers all six sides of the packaging box 8. A separate camera 3 can also photograph the label (containing barcodes and other identification information) affixed to the side of the packaging box 8. The software in the industrial control computer 6 can verify the information based on the MES system's inbound / outbound order number. Furthermore, after scanning the barcode, it can connect to the supplier's or customer's MES system to retrieve corresponding information (such as the number of boxes, batch number, product model, etc.). The photographed information is automatically archived and has online inspection and viewing functions. A limit on the number of photographs can also be added for confirmation. If the industrial control computer 6 software receives fewer than nine images, it will automatically issue an alarm.

[0035] The images captured can be automatically named according to the shipping order number / barcode or other information. After the images are captured, they can be automatically saved to both the specified local and network paths. For example, if the shipping order number is MSS2183020, the corresponding number of boxes is 2, and the file names are MSS2183020-1 and MSS2183020-2 respectively, with 9 images for each box.

[0036] If packaging box 8 fails to obtain a qualified image through appearance photography, the MES system can lock the packaging box 8, preventing it from proceeding to other processes or being shipped. Specifically, before processing the sales record or shipping, the MES system automatically verifies the batch photo quantity information on the shipping order. If no photos are taken or the number of photos is incomplete, the sales record cannot be processed or the product cannot be shipped, thus triggering a lockout.

[0037] When the device issues an alarm, manual verification and correction can be performed, along with subsequent processing such as rejection, rectification, or repackaging. Furthermore, the outer box photographing device provided by this invention can be designed according to the size of the largest possible package (8) for receiving / shipping, and the visual scanning field of view will be selected based on the largest single-sided field of view.

[0038] In terms of application effectiveness, in actual operation, it takes an average of 186 seconds to manually photograph each package box, while using the device provided in the above embodiment, automatic photography only takes 15 seconds, saving 181 seconds per box and improving efficiency by 97.3%.

[0039] It should be understood that the above embodiments are merely illustrative of the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
