Description

Technical Field

[0001] This utility model belongs to the field of visual positioning devices for multi-axis linkage packaging equipment, specifically a visual positioning device for multi-axis linkage packaging equipment. Background Technology

[0002] Multi-axis linkage packaging equipment refers to equipment that achieves complex process operations through the coordinated movement of multiple axes. As a type of multi-axis linkage packaging equipment, dispensing machines are usually equipped with multiple axes, including three linear axes (X, Y, and Z) and one or more rotary axes. They can precisely control the position and movement trajectory of the dispensing head in three-dimensional space to ensure accurate dispensing of adhesive at designated locations. This multi-axis linkage design enables dispensing machines to meet the dispensing needs of various shapes and complex structures, and they are widely used in packaging and coating operations in multiple industries such as electronics manufacturing, automobiles, and medical devices. Electronic components (such as Mini-LED chips and semiconductor wafers) are usually small in size and difficult to position accurately by manual or mechanical fixtures. Therefore, in the packaging process of dispensing machines, vision positioning devices are usually installed. These devices capture workpiece images with industrial cameras, combine them with algorithms to identify feature points, automatically identify positions and angles, and generate dispensing paths. This significantly improves dispensing efficiency and quality and reduces errors from manual operations. However, in practical applications, the installation space provided by the dispensing machine itself is relatively small and limited. This limitation directly leads to the fact that after the vision camera is fixedly installed, its shooting angle is difficult to adjust and optimize flexibly. This fixed shooting angle will undoubtedly have an adverse effect on the positioning accuracy and effect of the vision system, thus significantly reducing the overall performance and accuracy of vision positioning, and affecting the accuracy and efficiency of dispensing operations to a certain extent.

[0003] In summary, this utility model provides a visual positioning device for a multi-axis linkage packaging equipment to solve the above problems. Utility Model Content

Furthermore, some aspects of this utility model can be used alone or in any suitable combination with other aspects disclosed in this utility model.

[0015] Example 1 like Figure 1-5 As shown, this is the first embodiment of the present invention. This embodiment provides a visual positioning device for a multi-axis linkage packaging equipment, including a vision component 100, which includes a vision camera 110 and a light source 120; a support component 200, which includes a support plate 210 for supporting the vision component 100, a support rod 230 for fixing the light source 120, an adjustment block 240 and an adjustment bolt 250, an adjustment groove 260 and a second positioning bolt 290 for fixing the vision camera 110; and an adjustment component 300, which includes a fixed box 310, a connecting plate 320 located at the tail end of the vision camera 110, a transmission rod 330 that is pulverizedly connected to the connecting plate 320, a worm gear 340 and a worm wheel 350 located in the inner cavity of the fixed box 310, and a knob 360 located on the back of the fixed box 310, wherein the worm gear 340 and the worm wheel 350 are engaged.

[0016] like Figure 1-5As shown, the vision component 100 is the core component, and its vision camera 110 can accurately capture images of electronic components. Combined with the algorithm, it identifies feature points, thereby achieving precise positioning of small workpieces. This effectively solves the problem of inaccurate positioning by traditional manual or mechanical fixtures, and greatly improves the accuracy and efficiency of dispensing operations. The support plate 210 in the support assembly 200 is securely connected to the dispensing machine by bolts, ensuring the stability of the entire vision positioning device. At the same time, the support assembly 200 also includes positioning holes 270 and first positioning bolts 280 for fixing the fixing plate 220, so that the installation positions of the vision assembly 100 and the light source 120 can be flexibly adjusted according to actual needs. Even when the installation space of the dispensing machine is limited, it can ensure that the vision camera 110 obtains the best shooting angle, thereby improving the accuracy and effect of vision positioning. The adjustment component 300 achieves multi-angle adjustment of the vision camera 110 through the worm gear 350 and worm 340. This transmission method has self-locking properties, which can ensure that the vision camera 110 remains stable after adjustment and is not affected by equipment vibration or external forces. At the same time, the setting of the knob 360 allows the operator to easily manually adjust the angle of the vision camera 110, further improving the ease of use. In addition, the support rod 230 and adjustment block 240 in the support assembly 200 precisely adjust the position and angle of the light source 120 through the adjustment bolt 250 to ensure that the light can evenly cover the surface of the workpiece and provide ideal lighting conditions for the vision camera 110. This not only improves the accuracy of visual positioning, but also enables the entire device to maintain stable working performance in complex environments. Through the coordinated cooperation of the support assembly 200 and the adjustment assembly 300, the problem of the inability to adjust the angle of the vision camera 110 due to the limited installation space is effectively solved.

[0017] Example 2 Reference Figure 3 and 5 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0018] In this embodiment, the support plate 210 is fixedly connected to the dispensing machine by bolts, and the support assembly 200 also includes a positioning hole 270 and a first positioning bolt 280 for fixing the fixing plate 220.

[0019] The positioning hole 270 is opened at the front end of the top of the support plate 210 and is provided in several sets. One end of the first positioning bolt 280 passes through the fixing plate 220 and extends into the inner cavity of the positioning hole 270, and is threadedly connected to the inner cavity of the positioning hole 270.

[0020] One end of the support rod 230 is fixedly connected to the fixing plate 220, and the other end of the support rod 230 passes through the inner cavity of the adjusting block 240 and is movably connected to the inner cavity of the adjusting block 240. The adjusting bolt 250 passes through the adjusting block 240 and is tightly fitted to the support rod 230. The light source 120 is fixed to the bottom of the adjusting block 240.

[0021] The adjustment groove 260 is located at the rear end of the top of the support plate 210, and the bottom of the second positioning bolt 290 passes through the adjustment groove 260 and is threadedly connected to the fixing box 310.

[0022] like Figure 3 and 5 As shown, the fixing plate 220 is secured to the top front end of the support plate 210 by engaging with the positioning hole 270 on the support plate 210 via the first positioning bolt 280. Different positioning holes 270 can be selected for installation according to actual needs to adjust the horizontal position of the fixing plate 220. After the support rod 230 is fixedly connected to the fixing plate 220, the adjusting block 240 can slide along the support rod 230. The adjusting bolt 250 passes through the adjusting block 240 and fits tightly against the support rod 230, fixing the position of the adjusting block 240 on the surface of the support rod 230, thereby adjusting the position of the light source 120. The adjusting groove 260 is a long strip design, located at the rear end of the top of the support plate 210. The second positioning... Positioning bolt 290 passes through adjustment groove 260 and is threadedly connected to fixed box 310, allowing fixed box 310 to be adjusted horizontally at the rear end of support plate 210 and fixed by second positioning bolt 290. Support plate 210, as the base, is directly fixed to dispensing machine frame by bolts. Positioning holes 270 are distributed at the front end of support plate 210, which, together with first positioning bolt 280, realize multi-position pre-positioning of fixed plate 220. Support rod 230 passes through adjustment block 240 and is locked by adjustment bolt 250 to form single-point suspension structure, providing stable support for light source 120. Adjustment groove 260 provides horizontal degree of freedom adjustment for vision camera 110 and locks it in place with second positioning bolt 290.

[0023] Example 3 Reference Figure 2-5 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0024] In this embodiment, the fixing box 310 is located at the rear end of the bottom of the support plate 210, the bottom of the connecting plate 320 is fixedly connected to the vision camera 110, and the worm 340 and worm wheel 350 are rotatably connected to the inner wall of the fixing box 310 through bearings.

[0025] One end of the transmission rod 330 is fixedly connected to the connecting plate 320, and the other end of the transmission rod 330 is fixedly connected to the worm gear 350. One end of the knob 360 passes through the inner cavity of the fixed box 310 and is fixedly connected to the worm 340.

[0026] like Figure 2-5 As shown, the fixed box 310 is located at the bottom rear end of the support plate 210. The worm gear 340 and worm wheel 350 are installed inside through bearings. The transmission rod 330 passes through the fixed box 310 and is rigidly connected to the connecting plate 320. The knob 360 forms a rotary input interface with the end of the worm gear 340 through a threaded pair. By rotating the knob 360, the transmission system of the worm gear 340 and worm wheel 350 can be driven, thereby realizing the precise adjustment of the angle of the vision camera 110. Combined with the horizontal displacement function of the adjustment groove 260, precise positioning in two-dimensional space is achieved.

[0027] In use, simply rotate the knob 360, and the worm 340 will rotate accordingly. Due to the meshing relationship between the worm 340 and the worm wheel 350, the worm wheel 350 will also rotate accordingly, which in turn drives the connecting plate 320 to rotate through the transmission rod 330, ultimately achieving the adjustment of the angle of the vision camera 110. This adjustment method is not only highly accurate but also easy to operate, greatly improving work efficiency. At the same time, because the worm wheel 350 and worm 340 transmission has self-locking properties, the vision camera 110 can remain stable after adjustment and will not shift due to equipment vibration or external interference, ensuring the accuracy and stability of visual positioning.
