[0026] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0027] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a system, product, or device comprising a series of units is not necessarily limited to those steps or units explicitly listed, but may include other units not explicitly listed or inherent to such products or devices.

[0028] Example 1

[0029] Figure 1 This is a flowchart illustrating a detection method for a dispensing machine according to Embodiment 1 of the present invention. (Refer to...) Figure 1 As shown, the embodiments of the present invention can be applied to situations where dispensing and testing of products requiring adhesive are required. This method can be executed by the dispensing and testing device in the embodiments of the present invention. This system can be implemented by software and / or hardware, and can be integrated into the dispensing machine. The method specifically includes the following steps:

[0030] S110. The control scanning module performs a first scan of the product before dispensing along the first trajectory to obtain the first scan data.

[0031] Dispensing machines, also known as glue coaters, drippers, glue applicators, or glue dispensing machines, are specifically designed for fluid control. They are primarily used in product manufacturing processes to precisely dispense, inject, coat, or drip adhesives, paints, and other liquids onto specific locations on each product. They can be used to apply dots, lines, circles, or arcs. Currently, many products requiring dispensing have irregular shapes and uneven surfaces, thus demanding high precision in dispensing. Furthermore, a dispensing machine includes a processing module, a spraying module, and a scanning module. The processing module is electrically connected to both the spraying and scanning modules, allowing it to transmit dispensing and scanning commands to them respectively, thus enabling dispensing and scanning inspection of the product. Simultaneously, the processing module acquires the scanning structure from the scanning module, analyzes it, and obtains information on the dispensing status, completing the dispensing inspection process.

[0032] Furthermore, the processing module controls the scanning module to perform a first scan along the first trajectory line. The first trajectory can refer to the area scanned from the first end to the second end of the product before dispensing, and subsequent dispensing will be performed within this first trajectory area. During the first scan, the spraying module does not dispense adhesive onto the product; that is, the scanning module can acquire information such as the shape or surface condition of the product before dispensing, including the thickness, width, and distribution of the dispensing dots. This embodiment of the invention does not impose specific limitations on these aspects.

[0033] S120: Control the spraying module to apply adhesive to the product along the second trajectory, and simultaneously control the scanning module to perform a second scan of the product after adhesive application along the second trajectory to obtain the second scan data.

[0034] Furthermore, after the processing module controls the scanning module to perform the first scan along the first trajectory, the processor and the spraying module are positioned close to the end of the first trajectory. If the processing module controls the spraying module to perform dispensing, the dispensing process is performed along the second trajectory. The first and second trajectories are opposite trajectories. For example, if the area for dispensing in the product is a straight line, the first trajectory can be a straight line extending from the first end of the area to the second end, while the second trajectory is a straight line extending from the second end of the area to the first end. That is, the first and second trajectories are the same trajectory, only their directions of movement are opposite. Furthermore, the area for dispensing in the product can also be a circular area. In this case, the first trajectory can extend clockwise from the first end to the second end, and the second trajectory can extend counterclockwise from the second end to the first end. This embodiment of the invention does not specifically limit the shape of the dispensing area, i.e., the movement shape of the trajectory.

[0035] Furthermore, the processing module controls the spraying module to dispense adhesive onto the product along the second trajectory, thereby fulfilling the product's dispensing process requirements. While controlling the spraying module to dispense adhesive along the second trajectory, the processor also controls the scanning module to perform a second scan along the same trajectory. The second scanning trajectory can refer to scanning the product along the path of the first trajectory but in the opposite direction after dispensing, thereby acquiring information such as the shape or surface condition of the dispensed product. Since both the first and second scans target the same area of ​​the product, the accuracy is higher when comparing the two scans subsequently. Moreover, the processing module controls the scanning module to perform a second scan simultaneously with dispensing, improving the detection efficiency of the dispensing machine.

[0036] S130. Determine the dispensing information of the product based on the first scan data and the second scan data.

[0037] Furthermore, the first and second scan data acquired by the scanning module are transmitted to the processing module. The processing module can determine the dispensing information on the product based on the two scan structures, thereby achieving dispensing detection. For example, the dispensing information may include the thickness of the adhesive, the width of the dispensing, and the distribution of the dispensing dots. Since the scan data generated by the two scans correspond to the same scan position and the time interval is short, the accuracy of the acquired dispensing information can be guaranteed.

[0038] In summary, the embodiments of the present invention provide a dispensing detection method for a dispensing machine. Performing a second scan while the product is being dispensed can improve detection efficiency. Furthermore, using the detection method provided by the present invention, the product is scanned before and after dispensing on a first and second trajectory with opposite paths. The time interval between the two scans is short, while ensuring that the scanning positions are the same, thereby ensuring the accuracy of dispensing information acquisition.

[0039] Example 2

[0040] Figure 2 This is a schematic flowchart of a detection method for a dispensing machine provided in Embodiment 2 of the present invention. Figure 3 This is a schematic diagram of a dispensing machine according to Embodiment 2 of the present invention, with reference to... Figure 2 and Figure 3 As shown, this second embodiment refines the above embodiment, specifically detailing how to control the movement trajectories of the scanning module and the spraying module to achieve the dispensing detection action. In this embodiment, the method specifically includes the following steps:

[0041] S210. Adjust the laser output from the scanning module to center the laser on the first trajectory of the product.

[0042] Specifically, the scanning module outputs a laser beam, which scans the product to obtain its scanning information. For example, the scanning module can output a 3D line laser; however, this embodiment of the invention does not specifically limit the type of laser output by the scanning module. Furthermore, before controlling the scanning module to perform the scan, aligning the center of the output laser with the first trajectory of the product to be glued (i.e., pre-positioning) ensures the accuracy of the position during the subsequent first and second scans.

[0043] S220: Control the position adjustment module to move along the first trajectory and drive the scanning module to move along the first trajectory, and control the scanning module to perform the first scan of the product before dispensing.

[0044] The dispensing machine also includes a position adjustment module, and both the spraying module and the scanning module are fixedly connected to the position adjustment module. The processing module is electrically connected to the position adjustment module, meaning that the processing module controls the position movement of the position adjustment module, thereby enabling the position movement of the spraying module and the scanning module.

[0045] Specifically, by controlling the position adjustment module to move along the first trajectory, the scanning module is also moved along the first trajectory to scan the product before dispensing. Furthermore, the direction of travel of the first trajectory is the same as the direction from the spraying module to the scanning module; that is, when the position adjustment module moves along the first trajectory, the scanning module is positioned before the spraying module, and the spraying module does not dispense adhesive along this trajectory.

[0046] Optionally, the position adjustment module includes a motion axis and a fixing unit. The fixing unit is slidably connected to the motion axis and electrically connected to the processing module. The spraying module and the scanning module are fixedly connected to the fixing unit. For example, see reference... Figure 3As shown, the dispensing machine 10 includes a position adjustment module 100, which includes a motion axis 110 and a fixing unit 120. Specifically, when the processing module (not shown in the figure) controls the position adjustment module 100 to move, it controls the fixing unit 120 to slide on the motion axis 110. For example, the processing module and the position adjustment module 100 can be electrically connected or communicatively connected; this embodiment of the invention does not impose specific limitations on this. Furthermore, the fixing unit 120 is fixedly connected to the scanning module 200 and the spraying module 300, meaning the positional relationship between the scanning module 200 and the spraying module 300 is fixed. Therefore, when the fixing unit 120 moves along the first trajectory, the scanning module 200 and the spraying module 300 also move along the first trajectory. However, at this time, the scanning module 200 performs the first scan of the product, while the spraying module 300 does not dispense adhesive onto the product.

[0047] Specifically, the movement of the scanning module along the first trajectory may include: controlling the fixed unit to move along the first trajectory and slide on the motion axis to drive the scanning module to move along the first trajectory.

[0048] For example, the processing module controls the fixed unit to move on the motion axis, specifically along a first trajectory, so that the scanning module can acquire scanning information of the product before dispensing. (Reference) Figure 3 As shown, the product 20 is scanned for the first time by the dispensing machine 10 before dispensing. For example, the product 20 can be an LCD screen, etc. This embodiment of the invention does not specify a particular shape, nor does it specifically limit the shape and area of ​​the product 20 to be dispensed with glue. Specifically, the processing module controls the fixed unit 120 to move along the motion axis 110, thereby moving the scanning module 200. The first trajectory can be along the first end A of the product 20 to the second end B of the product 20. During the movement, the scanning module 200 scans the product 20 along the first trajectory. Based on the movement of the fixed unit 120, the spraying module 300 moves along with it. The spraying module 300 does not perform spraying during the first scan by the scanning module 200.

[0049] S230: Control the position adjustment module to move along the second trajectory and drive the spraying module and scanning module to move along the second trajectory, control the spraying module to apply glue to the product, and control the scanning module to perform a second scan on the product after glue application.

[0050] Specifically, after the first scan, the position adjustment module moves along the second trajectory, which in turn moves the spraying module and the scanning module along the same trajectory, enabling the dispensing of adhesive to the product and subsequent scanning. Furthermore, the direction of travel of the second trajectory is opposite to the direction from the spraying module to the scanning module. That is, when the position adjustment module moves along the second trajectory (opposite to the first trajectory), the scanning module is positioned after the spraying module, ensuring that the product is scanned a second time after dispensing while the scanning and spraying modules are moving.

[0051] Specifically, the movement of the scanning module and the spraying module along the second trajectory may include: controlling the fixed unit to move along the second trajectory and slide on the rotating shaft to drive the spraying module and the scanning module to move along the second trajectory.

[0052] For example, the processing module controls the fixed unit to move along the motion axis. After completing the first scan, i.e., after moving along the first trajectory, it moves along the second trajectory, enabling the spraying module to dispense adhesive onto the product and the scanning module to acquire the scanning information after dispensing adhesive. (Reference) Figure 3 As shown, after the dispensing machine 10 performs a first scan of the product 20 before dispensing, the fixing unit 120 drives the scanning module 200 and the spraying module 300 to move closer to the end of the first trajectory, that is, closer to... Figure 3 The second end B of product 20 is located at the second end of the product 20. The first trajectory can refer to movement from the first end A of product 20 to the second end B, while the second trajectory can refer to movement from the second end B of product 20 to the first end A; the two trajectories are in opposite directions. Specifically, the processing module controls the fixed unit 120 to move along the motion axis 110, thereby moving the spraying module 300 and the scanning module 200. During the movement, the spraying module 300 is positioned before the scanning module 200; that is, after dispensing adhesive onto product 20, the scanning module 200 performs a second scan of product 20. This ensures that the information from the two scans corresponds to the same position, facilitating accurate comparison of the dispensing information. Furthermore, since both the scanning module 200 and the spraying module 300 are fixed to the fixed unit 120, the interval between dispensing and subsequent information acquisition is short, further ensuring the accuracy of the dispensing information.

[0053] S240. Determine the dispensing information of the product based on the first scan data and the second scan data.

[0054] In summary, the dispensing detection method for a dispensing machine provided in this embodiment of the invention improves the accuracy of detection from all angles by first locating the relative position before scanning and dispensing, acquiring scanning data before and after dispensing, and scanning the product immediately after dispensing.

[0055] Example 3

[0056] Figure 4 This is a flowchart illustrating a detection method for a dispensing machine according to Embodiment 3 of the present invention. (Refer to...) Figure 4 As shown, this third embodiment refines the above embodiments, specifically detailing how to control and determine the dispensing information of the product. In this embodiment, the method specifically includes the following steps:

[0057] S310, The control scanning module performs a first scan of the product before dispensing along the first trajectory to obtain the first scan data.

[0058] S320: Control the spraying module to apply adhesive to the product along the second trajectory, and simultaneously control the scanning module to perform a second scan of the product after adhesive application along the second trajectory to obtain the second scan data.

[0059] S330. Determine the first scan image based on the first scan data.

[0060] Specifically, the processing module can convert the acquired first scan data into a first scan image using a data image conversion function. This image format ensures that subsequent result comparison and analysis are more intuitive and concrete.

[0061] S340. Determine the second scan image based on the second scan data.

[0062] Specifically, the processing module can convert the acquired second scan data into a second scan image using a data image conversion function. By using the image format, the subsequent comparison and analysis of the first and second scan images can be more intuitive and concrete.

[0063] S350. Determine the dispensing information of the product based on the first scanned image and the second scanned image.

[0064] Specifically, the processing module compares the acquired first scan image and second scan image. The first scan image is a scan image of the product without glue, and the second scan image is a scan image of the product with glue, thereby comparing and obtaining the glue information of the product.

[0065] Optionally, a stitching algorithm is used to stitch the first scanned image and the second scanned image together to obtain an integrated image; then an image mapping algorithm is used to obtain the dispensing information in the integrated image.

[0066] Specifically, the processing module can use a stitching algorithm to stitch the first and second scanned images together to obtain a stitched integrated image. When stitching the two scanned images, the horizontal and vertical coordinates of the images are aligned to obtain the dimensions of the product's scanned outline. Then, an image mapping algorithm is used to obtain the dispensing information from the integrated image. In other words, by using both image mapping and stitching algorithms, the determination of dispensing information can be more accurate, and the detection efficiency is also higher.

[0067] Optionally, when using an image mapping algorithm to obtain adhesive dispensing information in an integrated image, data points can be obtained from the integrated image, including a first data point and a second data point. The first data point is a data point from a first scanned image, and the second data point is a data point from a second scanned image. The difference between the first data point and the second data point is then obtained, and the difference is the thickness information of the adhesive dispensing.

[0068] For example, the first data point, i.e., the data information from the first scan, can be represented as coordinate data in the image, i.e., data1(i, j). The second data point, i.e., the data information from the second scan, can also be represented as coordinate data in the image, i.e., data2(i, j). By subtracting data2(i, j) from data1(i, j), the coordinate information of the difference is obtained, i.e., △data(i, j) = data1(i, j) - data2(i, j). △data(i, j) can represent the thickness of the adhesive dispensing, meaning that there is a thickness difference at the location of adhesive dispensing in the product, and no thickness difference at the location where adhesive is not dispensed. Through the calculation of the above coordinate data, the thickness information of the adhesive dispensing is obtained more intuitively and accurately. Furthermore, in addition to reflecting the thickness information of the adhesive dispensing, the data difference of the coordinates can also reflect the width information of the adhesive dispensing and the distribution of the adhesive dots, etc. This embodiment of the invention does not specifically limit this.

[0069] In summary, in the detection method for a dispensing machine provided by this embodiment of the invention, the two scan data obtained by the corresponding processing module can be converted into scan images by using a data-image conversion function, allowing for a more intuitive judgment of the dispensing situation. Furthermore, image mapping and stitching algorithms are employed to ensure that the obtained dispensing information is more accurate, thereby guaranteeing the accuracy of the dispensing detection method.

[0071] Figure 5 This is a schematic diagram of the structure of a dispensing detection device for a dispensing machine according to Embodiment 4 of the present invention. The device can be applied to products with dispensing and scanning functions, and the device can be implemented by software and / or hardware.

[0072] like Figure 5As shown, the dispensing machine 30 includes: a first scanning module 310, a second scanning and dispensing module 320, and a dispensing information determination module 330.

[0073] The first scanning module 310 is used to control the scanning module to perform a first scan of the product before dispensing along the first trajectory and obtain the first scan data.

[0074] The second scanning and dispensing module 320 is used to control the spraying module to dispense adhesive onto the product along the second trajectory, and at the same time control the scanning module to perform a second scan on the dispensed product along the second trajectory to obtain the second scan data; wherein, the first trajectory and the second trajectory are opposite trajectories.

[0075] The dispensing information determination module 330 is used to determine the dispensing information of the product based on the first scan data and the second scan data.

[0076] The dispensing detection device for a dispensing machine provided in this invention firstly uses a first scanning module to control the scanning module to perform a first scan of the product before dispensing along a first trajectory, acquiring first scan data. Then, a second scanning and dispensing module controls the spraying module to dispense adhesive onto the product along a second trajectory, while simultaneously controlling the scanning module to perform a second scan of the product after dispensing along the second trajectory, acquiring second scan data. The first and second trajectories are opposite. Finally, a dispensing information determination module determines the dispensing information of the product based on the first and second scan data. This solves the problem of low accuracy in dispensing detection in existing technologies, ensuring the accuracy of dispensing information acquisition.
