Description

Technical Field

[0001] This application relates to the field of industrial equipment testing technology, and in particular to a dispensing imaging testing device. Background Technology

[0002] In the assembly and manufacturing process of electronic products, especially camera modules, it is necessary to attach and bond protective covers and baffles to install electronic components and other parts for protection between them, while also maintaining electrical signal connection between the protective covers and baffles.

[0003] Therefore, it is usually necessary to fill the gap between the baffle and the protective cover with silver paste (conductive adhesive) to achieve both sealing and conductivity. However, in actual production, due to the limitations of the machine's baffle attachment precision, it is difficult to maintain a uniform gap between the baffle and the protective cover after attachment. This lack of precision leads to inconsistent adhesive application around the edges of the protective cover, resulting in assembly quality problems such as gaps and excess adhesive after the dispensing process. Therefore, there is an urgent need to develop an instrument for detecting the dispensing effect. Utility Model Content

[0004] This application provides a dispensing imaging detection device, which aims to provide an instrument for detecting dispensing effects and to solve the problem of poor dispensing consistency caused by insufficient precision in the dispensing process.

[0005] This application provides a dispensing imaging detection device in several embodiments, including a support, a light source assembly, a prism module, a lens module, and an imaging module. The light source assembly is connected to the support and illuminates a preset area, which is used to place an object to be inspected. The prism module and the lens module are connected to the support. The prism module includes an incident light side and an exit light side, with the incident light side facing the preset area. The imaging module is connected to the exit light side of the prism module via the lens module and is used to acquire a recognition image of the object to be inspected at the preset area.

[0007] Optionally, the first light source is a 0° light source.

[0008] Optionally, the light source assembly further includes a second light source frame and a second light source element. The second light source frame is detachably connected to the support, and the first and second light source frames are spaced apart along the incident light direction of the prism module. The second light source element is connected to the second light source frame, and the second light source element is a 90° light source.

[0009] Optionally, the first light source holder is rotatably connected to the bracket to switch between a first position and a second position. When the first light source holder is in the first position, the first light source illuminates a preset area.

[0010] Optionally, the second light source holder is rotatably connected to the support frame to switch between a third position and a fourth position. When the second light source holder is in the third position, the second light source illuminates a preset area.

[0011] Optionally, the support includes a platform and at least two legs. A prism module, a lens module, and an imaging module are mounted on the bearing surface of the platform. The legs are connected to the platform and support it. One leg extends along its length to one side of the platform's bearing surface for detachable connection to the light source assembly.

[0012] Optionally, the support also includes a first adjustment seat and a second adjustment seat. The first adjustment seat is detachably connected to the stage panel, the second adjustment seat is connected to the first adjustment seat, and the imaging module is connected to the side of the second adjustment seat away from the first adjustment seat.

[0013] Optionally, the first and second adjustment seats shown are integrally formed structures.

[0014] Optionally, the first adjusting seat is provided with at least two first strip-shaped holes extending along a first direction, and the first adjusting seat is connected to the table panel through the first strip-shaped holes. The table panel is provided with at least two second strip-shaped holes extending along a second direction, and the table panel is connected to the first adjusting seat through the second strip-shaped holes, with an included angle between the first direction and the second direction.

[0015] Optionally, the support also includes at least one of a prism base and a lens mount. The prism module is detachably connected to the stage panel via the prism base. The lens module is detachably connected to the stage panel via the lens mount.

[0016] Optionally, the dispensing imaging inspection device also includes a code reading component, which is connected to the bracket and is used to detect the identification code of the object to be inspected. The identification code includes at least a barcode or a QR code.

[0017] The technical solutions provided in this application have the following advantages compared with the prior art:

[0018] In the aforementioned dispensing imaging detection device, after the object to be detected is placed in a preset area, the light source assembly projects light onto the adhesive surface of the object from different angles. After reflection from the adhesive surface, the light enters the light-incident side of the prism module. Through total internal reflection within the prism, the propagation path is altered, converting the adhesive image originally located at the bottom (or side) region into a horizontal (or vertical) light signal. The adjusted light signal is then focused by the lens module and transmitted to the imaging module, enabling the imaging module to acquire a clear recognition image.

[0019] Subsequently, image processing algorithms can be used to analyze the filling state of the colloid in the three-dimensional gap, so as to accurately determine whether the dispensing process has met the preset precision requirements. This optical path design allows the bottom (or side) area, which was originally impossible to image directly, to be effectively captured, while avoiding positioning errors caused by mechanical structure adjustments.

[0020] Through the above technical solution, this application achieves accurate detection of dispensing quality in three-dimensional gaps, effectively identifying defects such as incomplete glue filling and glue overflow. This device replaces traditional manual visual inspection with non-contact optical detection, improving the automation level of electronic component assembly while ensuring detection accuracy and solving the problem of uncontrolled dispensing quality caused by mounting accuracy deviations. Furthermore, this solution uses a prism module to achieve optical path folding, improving the imaging quality of the recognized image while avoiding the large length space occupied by a single-direction optical path, thus enhancing the flexibility and adaptability of the dispensing imaging detection device during layout and installation.

[0033] 200. Item to be tested. Detailed Implementation

[0034] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0035] The following provides many different embodiments or examples for implementing different structures of this application. To simplify the scheme of this application, the components and arrangements of specific examples are described below. Of course, these are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0036] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0037] like Figure 1 and Figure 2 As shown, in the assembly and manufacturing process of electronic products, especially camera module 01, it is necessary to attach and bond the protective cover 011 and the baffle 012 to install electronic components and other parts for protection between them, while also maintaining an electrical signal connection between the protective cover 011 and the baffle 012.

[0038] Therefore, it is usually necessary to use the gap area between the baffle 012 and the protective cover 011 (i.e. Figure 1 At point A in the diagram, silver paste (conductive adhesive) is applied to achieve both sealing and conductivity between the two surfaces. The application trajectory of the silver paste at protective cover 011 is as follows: Figure 2 Example at point B in the text.

[0039] However, in actual production, due to the precision limitations of the machine's attachment baffle 012, the gap between the baffle 012 and the protective cover 011 after attachment (e.g.) Figure 1 The adhesive application at point A is difficult to maintain uniformity. This lack of precision leads to inconsistent adhesive application around the edges of the protective cover 011, resulting in assembly quality issues such as gaps and excess adhesive after the application process. Therefore, there is an urgent need to develop an instrument for testing the adhesive application effect.

[0040] Based on this, please refer to Figures 3 to 6 This application provides a dispensing imaging detection device, which aims to provide an instrument for detecting dispensing effects and to solve the problem of poor dispensing consistency caused by insufficient precision in the dispensing process.

[0041] like Figure 3 and Figure 4 As shown, the dispensing imaging detection device includes a support 10, a light source assembly 20, a prism module 30, a lens module 40, and an imaging module 50. The light source assembly 20 is connected to the support 10 and is used to illuminate a preset area, which is used to place the object 200 to be inspected. The prism module 30 and the lens module 40 are connected to the support 10. The prism module 30 includes an incident light side and an exit light side, with the incident light side facing the preset area. The imaging module 50 is connected to the exit light side of the prism module 30 through the lens module 40 and is used to acquire a recognition image of the object 200 to be inspected at the preset area.

[0042] It should be noted that, Figure 4 The position of the object to be inspected 200 can be a preset object. Alternatively, the object to be inspected 200 can be moved up or down to a preset area by a robotic arm or fixture, and there is no limitation on this.

[0043] Among them, the object to be inspected 200 refers to electronic products such as camera modules assembled and manufactured by adhesive bonding. Since the adhesive baffle and the protective cover need to maintain an electrical signal connection, and silver paste (a type of conductive paste) has a good reflective effect, the identification image of the object to be inspected 200 at the bonding area can be captured by video imaging. Subsequently, the identification image can be analyzed by software or manually to determine whether there are quality problems such as gaps and glue overflow after the dispensing process.

[0044] The prism module 30 refers to an optical element with optical path reversal function, which can be implemented using a right-angle prism or a pentaprism. The light-incident side of the prism module 30 receives the light signal from the area to be detected and changes the direction of light propagation through internal reflection.

[0045] The light source assembly 20 refers to a device that provides multi-angle illumination, which can be implemented using an adjustable LED array. By combining light at different incident angles, the imaging clarity of the colloid edge can be enhanced. This improves the imaging clarity of the image of the object 200 to be detected in the preset area at the imaging module 50.

[0046] Lens module 40 refers to an optical system with a specific or adjustable focal length. For example, lens module 40 may use a fixed-focus industrial lens to focus the light signal refracted by the prism onto imaging module 50, so that imaging module 50 can acquire a relatively clear recognition image.

[0047] For example, after the object to be detected 200 is placed in a preset area, the light source assembly 20 projects light onto the colloidal surface of the object to be detected 200 from different angles. After being reflected by the colloidal surface, the light enters the light-incident side of the prism module 30. The propagation path is changed by the total internal reflection inside the prism, converting the colloidal image originally located in the bottom (or side) area into a light signal in the horizontal (or vertical) direction. The adjusted light signal is focused by the lens module 40 and transmitted to the imaging module 50 so that the imaging module 50 can acquire a clear recognition image.

[0048] Subsequently, image processing algorithms are used to analyze the filling state of the colloid in the three-dimensional gap to accurately determine whether the dispensing process has met the preset precision requirements. This optical path design allows the bottom (or side) area, which was originally impossible to image directly, to be effectively captured, while avoiding positioning errors caused by mechanical structure adjustments.

[0049] Through the above technical solution, this application achieves accurate detection of dispensing quality in three-dimensional gaps, effectively identifying defects such as incomplete glue filling and glue overflow. This device replaces traditional manual visual inspection with non-contact optical detection, improving the automation level of electronic component assembly while ensuring detection accuracy and solving the problem of uncontrolled dispensing quality caused by mounting accuracy deviations. Furthermore, this solution uses a prism module 30 to achieve optical path folding. While improving the imaging quality of the recognized image, the folded optical path also avoids the large length space occupied by a single-direction optical path, which is beneficial to improving the flexibility and adaptability of the dispensing imaging detection device during layout and installation.

[0050] The illumination of the preset area by the light source also affects the imaging quality of the recognized image. For example... Figure 4 and Figure 5 As shown, the light source assembly 20 includes a first light source frame 21 and a first light source element 22. The first light source frame 21 and the bracket 10 (see reference) Figure 3 The first light source component 22 is detachably connected to the first light source frame 21 and is used to illuminate a preset area.

[0051] The first light source bracket 21 refers to the support structure used to install the first light source component 22. For example, the first light source bracket can be a metal bracket with screw fixing interface or a plastic bracket with buckle structure, which is used to provide a stable installation base for the first light source component 22 and allow the position of the light source to be adjusted through disassembly operation.

[0052] The first light source 22 refers to a light-emitting element that directly generates light, such as an LED (Light Emitting Diode) light strip or a laser emitter, used to provide directional illumination to a preset area to ensure that the imaging module 50 can capture a clear and recognizable image of the object 200 to be detected.

[0053] Based on this, the light source assembly 20 is modularly installed through a detachable connection between the first light source frame 21 and the bracket 10. When it is necessary to adjust the light source illumination angle or change the light source type, the first light source frame 21 can be detached from the bracket, repositioned or replaced, and then fixed. The first light source element 22 is installed at a specific position on the first light source frame 21 to ensure that the light is concentrated and projected onto the preset area where the object to be inspected 200 is located. During the inspection process, the illumination direction of the light source can be adaptively adjusted according to the layout of the prism module 30 and the lens module 40. For example, by changing the installation angle of the first light source frame 21 on the bracket 10, the light can cover the edge gap area of ​​the object to be inspected 200.

[0054] This solution utilizes a detachable light source frame structure, enabling the light source assembly 20 to be quickly disassembled, assembled, and positioned according to the size, shape, and gap distribution of the object to be tested 200. This allows for flexible adjustment of the light source position and angle, adapting to gap changes caused by different attachment deviations, ensuring stable illumination conditions and imaging quality in the dispensing area, thereby effectively detecting the silver paste filling status and reducing missed or false detections.

[0055] The first light source 22 is a 0° light source. A 0° light source means that the incident light direction is parallel to the surface normal direction of the object to be inspected 200. Alternatively, the light direction of the first light source 22 is approximately parallel to the incident light from the prism module 30. This can be achieved by using a parallel LED array installed directly facing the preset area, allowing the light to directly and perpendicularly illuminate the surface of the object to be inspected 200. This light source can eliminate shadow interference caused by incident angle deviation, thereby improving the imaging clarity of surface details.

[0056] For example, when the object to be inspected 200 is placed in a preset area, a 0° light source projects uniform light in a direction perpendicular to the object. The prism module 30 guides the reflected light path to the lens module 40, and finally the imaging module 50 captures a high-contrast surface image. By analyzing the light and dark distribution of the silver paste-filled area in the image, it can be determined whether there are any defects such as gaps or excess glue.

[0057] Because tilted light sources are prone to localized reflections or shadows due to differences in gap structure, resulting in blurred image details, 0° light sources, through perpendicular illumination, can eliminate light scattering caused by fluctuations in gap size, ensuring consistent glue morphology across different areas in the image. Therefore, by setting the first light source 22 to a 0° light source, perpendicularly incident light can clearly reveal the glue distribution in the gap area, avoiding misjudgments caused by changes in light angle, thereby improving the reliability of the detection system in identifying defects such as glue overflow and leaks.

[0058] In some embodiments, such as Figure 3 and Figure 4 As shown, the light source assembly 20 also includes a second light source frame 23 and a second light source element 24. The second light source frame 23 is detachably connected to the bracket 10. The first light source frame 21 and the second light source frame 23 are spaced apart along the incident light direction of the prism module 30. The second light source element 24 is connected to the second light source frame 23 and is a 90° light source.

[0059] The second light source bracket 23 refers to the support structure used to fix the second light source component 24. The second light source bracket 23 can be made of metal or plastic and is connected to the bracket 10 by bolts or clips, facilitating adjustment of the installation position according to testing requirements. The staggered distribution along the incident light direction of the prism module 30 means that the first light source bracket 21 and the second light source bracket 23 are arranged staggered along the direction in which the prism module 30 receives light. For example, the first light source bracket 21 and the second light source bracket 23 are staggered along the height direction, so that the illumination range of the two light sources forms complementary coverage.

[0060] A 90° light source refers to an illumination device whose light projection direction forms a 90° angle with the normal direction of the surface of the preset area (or the incident light direction of the prism module 30). Specifically, it can adopt a side-arranged LED bead or a light guide plate structure to enhance the contrast between the light and dark areas of the side wall or edge area of ​​the object to be inspected 200.

[0061] For example, the second light source frame 23 is mounted on the bracket 10 and is spaced apart from the first light source frame 21 along the height direction. The second light source element 24 is fixed on the second light source frame 23 and emits side light into the preset area using a 90° light source. When the object to be tested 200 is placed in the preset area, the 0° light source of the first light source element 22 illuminates from the front, and the 90° light source of the second light source element 24 illuminates from the side. After being reflected by the object to be tested 200, the light from the two light sources is refracted by the prism module 30 and captured by the imaging module 50, forming an image containing illumination information from different angles. By analyzing the brightness changes and contour clarity of the glue edge in the image, it can be determined whether there are defects such as leaks or glue overflow.

[0062] This solution, by adding a second light source bracket and a 90° light source, combines two different angles of light coverage to significantly improve the imaging contrast of the adhesive edge area, thereby more accurately identifying problems such as uneven adhesive layer thickness or discontinuous boundaries. In other words, through multi-angle light source collaborative imaging, the integrity of adhesive coverage in gap areas can be effectively identified, avoiding missed detections or misjudgments caused by the limited illumination range of a single light source, thus improving the reliability of adhesive dispensing quality inspection.

[0063] The first light source holder 21 can be rotatably connected to the bracket 10 to switch between a first position and a second position. When the first light source holder 21 is in the first position, the first light source element 22 illuminates a preset area. That is, the second position is the standby position of the first light source element 22.

[0064] The rotatable connection between the first light source holder 21 and the support 10 refers to the adjustment of the angle of the first light source holder 21 relative to the support 10 through a rotating shaft or hinge structure. Specifically, a connector with a damping rotating shaft can be used to achieve this, allowing the first light source holder 21 to stably stay in the desired position after rotation. The first position is the vertical illumination state where the first light source 22 is directly facing the preset area, so as to illuminate the preset area and enable the imaging module 50 to acquire a relatively clear recognition image. The second position is the storage state where the first light source 22 is offset from the preset area, at which time the first light source 22 can be in standby or maintenance state.

[0065] Correspondingly, the second light source holder 23 is rotatably connected to the bracket 10, allowing it to rotate and switch between the third and fourth positions. When the second light source holder 23 is in the third position, the second light source element 24 illuminates a preset area. The fourth position can be a standby position for the second light source element 24, allowing for selection of either the first light source element 22 or the second light source element 24 via position switching. Alternatively, the second light source element 24 may also have other functions in the fourth position.

[0066] The second light source holder 23 is rotatably connected to the support 10 in the same way as the first light source holder 21. The third position is the working state where the second light source 24 illuminates the preset area at a vertical angle, so as to illuminate the preset area and enable the imaging module 50 to acquire a relatively clear recognition image. The fourth position is a standby state or a maintenance state, or a non-working state, to avoid the detection area. Alternatively, the second light source 24 at the fourth position may also have other functions.

[0067] For example, when it is necessary to inspect the quality of the silver paste filling in the gap area between the baffle and the protective cover, the first light source holder 21 is rotated to the first position so that the 0° light source vertically illuminates the gap area, at which point the light source directly covers the surface features of the area to be inspected. If it is necessary to adjust the light source angle to eliminate reflection interference, the second light source holder 23 can be rotated to the third position so that the 90° light source provides supplementary illumination from the side. When the inspection process is completed or equipment maintenance is required, the light source holder can be rotated to the second or fourth position to free up operating space. By switching the position of the light source holder, it is possible to adapt to the inspection requirements of different gap sizes and shapes, avoiding the problem of blind spots or reflection interference caused by fixed light sources.

[0068] In some embodiments, such as Figure 3 and Figure 5As shown, the dispensing imaging detection device also includes a code reading component 60, which is connected to the bracket 10 and is used to detect the identification code of the object to be detected 200. The identification code includes at least a barcode or a QR code.

[0069] The code reading component 60 refers to a device that can read coded information through optical scanning or image recognition. Specifically, it can be implemented by using a barcode scanner or camera combined with a decoding algorithm to automatically obtain the identification information of the object 200 to be detected.

[0070] An identification code is a coded form that contains a unique identifier for a product or production information. Specifically, it can be implemented using a barcode or a QR code. By encoding and storing product model, batch, or serial number, it ensures the correspondence between test results and objects.

[0071] For example, during the dispensing inspection process, the barcode reader 60 is integrated into the bracket 10, and its position can be adjusted to accommodate objects 200 of different sizes to be inspected. Before or after the object 200 is placed in the preset area, the barcode reader 60 can scan or photograph the identification code, and associate the acquired coded information with the recognition image generated by the imaging module 50. For example, when inspecting the silver paste filling status, the barcode reader 60 simultaneously reads the object's QR code, and the system binds and stores the product information corresponding to the QR code with the image detection result of the dispensing area, avoiding matching errors caused by manual recording.

[0072] Traditional testing methods rely on manual recording of product information, which carries the risk of data errors and omissions. This solution, however, integrates a barcode reader component 60 to automatically associate testing data with the object under test 200, while also being compatible with multiple encoding formats, reducing manual intervention. This solves the problem of the inability to automatically match testing results with product information, ensuring that the dispensing status of each object under test 200 accurately corresponds to its unique identifier, thus improving the automation and reliability of the testing process.

[0073] It should be noted that the code reading component 60 may include a code reading lens and a code reading camera. Before being placed in the preset area, the object to be detected 200 can be placed in the acquisition area of ​​the code reading lens to acquire and identify the identification code of the object to be detected 200 to associate it with the identification image acquired in the preset area. The second light source 24, located in the fourth position, can also be used to illuminate the acquisition area, enabling the code reading component 60 to accurately and quickly acquire the identification code of the object to be detected 200.

[0074] In some embodiments, such as Figure 3 and Figure 5As shown, the support 10 includes a platform 11 and at least two legs 12. A prism module 30, a lens module 40, and an imaging module 50 are mounted on the bearing surface of the platform 11. The legs 12 are connected to the platform 11 and support it. One of the legs 12 extends along its length to one side of the bearing surface of the platform 11 for detachable connection to the light source assembly 20.

[0075] The tabletop 11 refers to the flat structure used to support the prism module 30, lens module 40, and imaging module 50. It can be made of metal or high-strength composite materials to provide a stable mounting base. The legs 12 are the column structures supporting the tabletop 11. They can be height-adjustable threaded rods or telescopic rods to accommodate differences in the height of different work surfaces. The bearing surface refers to the planar area on the tabletop 11 used for mounting optical components. Precision machining ensures flatness and prevents misalignment of the optical components.

[0076] Taking the bearing surface located on the upper side of the platform 11 as an example, the light source assembly 20 is detachably connected to the end of a long support leg 12. The connection between the support leg 12 and the light source assembly 20 is achieved by means of threaded fasteners or snap-fit ​​structures, which facilitates quick replacement or adjustment of the light source position according to the testing requirements.

[0077] For example, the platform 11 is fixed to the working area by support legs 12. The prism module 30, lens module 40, and imaging module 50 mounted on the support surface constitute an optical detection path. One of the support legs 12 extends to the support surface side, and the light source assembly 20 is detachably fixed to the support leg 12 to form a stable illumination angle. When the object to be inspected 200 is placed in the preset area, the light source assembly 20 provides uniform illumination. The light is refracted by the prism module 30 and enters the lens module 40, and finally the imaging module 50 acquires and identifies the image. The extended design of the support leg 12 allows the position of the light source assembly 20 to be adjusted according to the length of the support leg 12, and the installation angle of the light source can also be adjusted around the support leg 12 to avoid light coverage deviation caused by insufficient machine attachment accuracy.

[0078] It should be noted that, as Figure 5 As shown, if there are two support legs 12, the bracket 10 also includes a support leg seat 17, that is, at least one of the support legs 12 is connected to the support leg seat 17 at its lower end. The extension direction of the support leg seat 17, the length direction of the table panel 11 and the length direction of the support leg 12 are perpendicular to each other or have an angle, so as to stably support the table panel 11.

[0079] Alternatively, the number of support legs 12 can be set to at least three, which can also stably support the platform panel 11.

[0080] Thus, through the above technical solution, the installation position of the light source component 20 can be flexibly adjusted according to the actual gap between the baffle and the protective cover, avoiding uneven illumination caused by insufficient machine attachment precision, improving the image acquisition quality of the silver paste filling area, and thereby improving the detection accuracy of gap and glue overflow defects.

[0081] When installing imaging module 50, such as Figure 3 and Figure 5 As shown, the bracket 10 also includes a first adjustment seat 13 and a second adjustment seat 14. The first adjustment seat 13 is detachably connected to the table panel 11, the second adjustment seat 14 is connected to the first adjustment seat 13, and the imaging module 50 is connected to the side of the second adjustment seat 14 away from the first adjustment seat 13.

[0082] The first adjustment seat 13 and the second adjustment seat 14 are detachably connected, which facilitates flexible adjustment of the installation height of the imaging module 50 by replacing the first adjustment seat 13 and the second adjustment seat 14 with different height dimensions.

[0083] The first adjustment seat 13 and the second adjustment seat 14 can be a split structure, that is, the first adjustment seat 13 and the second adjustment seat 14 can be detachably connected. When adjusting the height position of the imaging module 50, the first adjustment seat 13 or the second adjustment seat 14 with different height dimensions can be replaced.

[0084] Alternatively, the first adjustment seat 13 and the second adjustment seat 14 can also be an integrally formed structure, that is, the two are a single component, in order to reduce the number of parts in the whole machine. In this case, when adjusting the height position of the imaging module 50, the integral component of the first adjustment seat 13 and the second adjustment seat 14 can be replaced.

[0085] To facilitate adjustment of the horizontal position of the imaging module 50, such as Figure 5 As shown, the first adjustment seat 13 is provided with at least two first strip holes 131. The first strip holes 131 extend along the first direction X, and the first adjustment seat 13 is connected to the table panel 11 through the first strip holes 131.

[0086] By connecting the first adjustment seat 13 to the platform 11 via the first slot 131, when the horizontal position of the imaging module 50 needs to be adjusted, the fixing bolts can be loosened and the first adjustment seat 13 can be moved along the first slot 131, and then the bolts can be tightened again. This allows the installation position of the first adjustment seat 13 to be adjusted in the first direction X. Since the lens module 40 is connected to the first adjustment seat 13 via the second adjustment seat 14, the installation position of the lens module 40 in the first direction X can be adjusted synchronously.

[0087] Correspondingly, such as Figure 6As shown, the tabletop 11 is provided with at least two second strip-shaped holes 111, which extend along a second direction Y. The tabletop 11 is connected to the first adjusting seat 13 through the second strip-shaped holes 111. The second direction Y has an angle with the first direction X.

[0088] Thus, by connecting the platform 11 to the first adjusting seat 13 via the second slot 111, when the horizontal position of the imaging module 50 needs to be adjusted, the fixing bolts can be loosened and the first adjusting seat 13 can be moved along the second slot 111, and then the bolts can be tightened again. This allows for adjustment of the mounting position of the first adjusting seat 13 in the second direction Y. Since the lens module 40 is connected to the first adjusting seat 13 via the second adjusting seat 14, the mounting positions of the lens module 40 and the second adjusting seat 14 in the second direction Y can be adjusted simultaneously.

[0089] Taking the first direction X and the second direction Y as two mutually perpendicular directions in the horizontal plane as an example, the bolt passes through the first strip hole 131 and the second strip hole 111 in sequence along the vertical direction to connect the first adjusting seat 13 and the platform 11. Through the aforementioned arrangement of the first strip hole 131 and the second strip hole 111, the installation position of the first adjusting seat 13 relative to the platform 11 can be flexibly adjusted within the second direction Y and the first direction X, facilitating flexible adjustment of the installation position of the imaging module 50 relative to the platform 11 in the horizontal plane.

[0090] Thus, the configuration of the first adjustment seat 13 and the second adjustment seat 14 facilitates flexible adjustment of the installation position of the imaging module 50 in the three-dimensional space of up and down, front and back, and left and right, thereby avoiding the inability to correct optical path offset caused by installation errors or equipment aging, which would affect the detection accuracy.

[0091] This solution utilizes a detachable, dual-layer adjustable base structure, enabling flexible adjustment of the imaging module's position. This allows for fine-tuning of the module's horizontal and vertical positions to adapt to optical path calibration requirements under various operating conditions. It resolves image shift issues caused by installation errors or equipment deformation, improves the clarity of the dispensing area image and the accuracy of detection results, thereby effectively preventing missed or false detections.

[0092] like Figure 3 and Figure 5 As shown, the bracket 10 also includes at least one of the prism base 15 and the lens holder 16.

[0093] The prism module 30 is detachably connected to the stage panel 11 via the prism base 15. The prism base 15 is a support structure used to fix the prism module 30. Specifically, it can be a metal or non-metal base with positioning grooves and locking bolts. By adjusting the tightness of the locking bolts, the installation position of the prism module 30 on the stage panel can be controlled, thereby ensuring that the light incident side of the prism module 30 is accurately aligned with the preset area.

[0094] The prism base 15 is detachably connected to the threaded hole of the platform 11 by bolts. When it is necessary to adjust the horizontal position of the prism module 30, the bolts can be loosened and the prism base 15 can be slid to the target position on the surface of the platform 11 and then locked again.

[0095] In addition, the mounting height of the prism module 30 can be adjusted by replacing the prism base 15 with different heights and sizes to accommodate lens modules 40 with different height requirements.

[0096] Correspondingly, the lens module 40 is detachably connected to the table panel 11 via the lens holder 16. The lens holder 16 refers to the mounting component used to support the lens module 40. For example, it can be implemented using a bracket structure with slide rails and clips. The distance between the lens module 40 and the light-emitting side of the prism module 30 can be adjusted via the slide rails, and different specifications of the lens module 40 can be quickly disassembled and replaced via the clips.

[0097] In some embodiments, the prism base 15 can be replaced with a mounting plate with magnetic adsorption function, which is connected to the table panel 11 by magnetic attraction. The lens holder 16 can be replaced with a fixing base with a spring clamping structure, which clamps lens modules of different diameters by spring pressure.

[0098] By setting up a detachable prism base 15 and lens holder 16, the position of the optical components can be flexibly adjusted according to the actual working conditions, thus solving the problem of detection failure caused by insufficient baffle attachment accuracy.
