Description

Technical Field

[0001] This utility model relates to the field of dispensing device technology, and in particular to dispensing devices. Background Technology

[0002] In a dispensing device, the dispensing effect of the needle assembly cannot be observed with the naked eye. The conventional method for monitoring the dispensing status is to install a camera on one side of the needle assembly, point the camera at the dispensing port of the needle assembly, and use the camera to collect images of the dispensing port in real time to obtain the dispensing status.

[0003] Currently, the dispensing status of the dispensing nozzle is observed using a high-magnification fixed-magnification camera. However, the disadvantage of this type of camera is that the field of view is relatively small, and directly moving the camera can easily lead to unclear observation of the object and defocusing. In addition, when changing needle components of different sizes in the dispensing device, the camera may not be able to align with the dispensing nozzle or focus, and the process of adjusting the camera to align with and focus on the dispensing nozzle of the new needle component is quite difficult.

[0004] Therefore, there is an urgent need for a dispensing device to solve the above problems. Utility Model Content

[0042] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0043] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly.

[0044] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0045] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0046] This embodiment discloses a dispensing device, such as... Figures 1-2 As shown, the dispensing device includes a frame 1, a dispensing mechanism 2, an adjusting component 3, a swivel component 4, a guide fastener (not shown), and a camera 5. The dispensing mechanism 2 is connected to the frame 1 and includes a needle assembly 21, the lower end of which is the dispensing port. The adjusting component 3 includes a fixed end and a movable end. The fixed end is connected to the frame 1, and the movable end can slide or lock relative to the fixed end along a first direction and a second direction, the first direction and the second direction being perpendicular to each other. The swivel component 4 is provided with a first arc-shaped hole 41. 1. The center point of the dispensing port is taken as the arc center; the guide fastener passes through the first arc hole 41 and is connected to the movable end. When the swing member 4 rotates relative to the movable end, the guide fastener can slide in the first arc hole 41. The guide fastener is used to lock the relative position between the swing member 4 and the movable end, so that the swing member 4 can rotate or lock relative to the movable end along the arc direction of the first arc hole 41 around the center point of the dispensing port; the camera 5 is connected to the swing member 4. The camera 5 is used to collect images of the dispensing port to monitor the dispensing status of the dispensing port.

[0047] When the dispensing device is in operation, the movable end of the adjusting component 3 slides along the first and second directions, driving the swivel component 4 and camera 5 for initial adjustment, and then the movable end is locked. The swivel component 4 is then pushed, causing the guide fastener to slide along the arc direction of the first arc hole 41, allowing the swivel component 4 to rotate around the center point of the dispensing nozzle until the camera 5 is aligned with and focused on the dispensing nozzle, at which point the swivel component 4 is locked. This dispensing device achieves multi-angle adjustment of the camera 5 through the bidirectional sliding of the adjusting component 3 and the arc rotation of the swivel component 4, enabling the camera 5 to quickly align with the dispensing nozzles of needle components 21 of different sizes, improving adjustment efficiency, and ensuring the real-time and accurate monitoring of the dispensing status.

[0048] like Figures 1-2 As shown, when the oscillating component 4 is in its initial position, the extension direction of the camera 5 is perpendicular to the extension direction of the needle assembly 21. The extension direction of the camera 5 is the first direction, and the extension direction of the needle assembly 21 is the second direction. When the oscillating component 4 rotates upward around the center point of the dispensing nozzle along the arc direction of the first arc hole 41, it can view the dispensing nozzle from above, expanding the monitoring angle. It can observe the side state of the dispensing nozzle vertically and also view the overall shape of the dispensing nozzle from above, adapting to different dispensing monitoring needs. This allows the high-pixel camera 5 to accurately capture multi-dimensional details, improving the comprehensive monitoring of the dispensing status of the needle assembly 21. At the same time, after monitoring is completed, the camera 5 is retracted upward, so that the position of the camera 5 is higher than that of the needle assembly 21, avoiding collisions between the camera 5 and the needle assembly 21 or other components, ensuring the safe operation of the dispensing device, and reducing the risk of damage to the camera 5 and needle assembly 21 and downtime for maintenance due to collisions.

[0049] In this embodiment, camera 5 is a high-pixel camera equipped with a high-magnification high-definition lens, which can clearly capture the subtle state of the dispensing nozzle, accurately identify details such as the amount of glue and the shape of the glue line, present high-definition images, focus on key areas of dispensing, provide high-precision visual support for dispensing status monitoring, reduce judgment errors caused by image blurring, and improve the reliability of dispensing quality control.

[0050] In this embodiment, the dispensing device also includes a light source 8, which is mounted on the frame 1. The light source 8 illuminates the dispensing nozzle and provides lighting support for the camera 5, reducing image blurring caused by insufficient ambient light, improving the clarity and contrast of the dispensing nozzle image, and enabling the camera 5 to more accurately capture details of the dispensing status. Especially when the field of view of the high-magnification camera 5 is small, stable lighting can enhance the distinction between the dispensing nozzle and the surrounding environment. Combined with the monitoring function of the camera 5, it ensures more reliable identification of the dispensing status of different needle components 21 and improves monitoring accuracy.

[0051] like Figures 1-2As shown, the oscillating component 4 has multiple first arc holes 41, and the movable end has multiple corresponding positioning holes 332. Each of the multiple first arc holes 41 has its arc center at the center point of the glue outlet, and the radii of the multiple first arc holes 41 are different from each other. Multiple guide fasteners are respectively inserted into the multiple first arc holes 41 and are fixedly connected to their corresponding positioning holes 332. This enhances the stability of the oscillating component 4 during rotation, prevents camera 5 from shaking, ensures the stability of camera 5's posture during rotation adjustment, further improves adjustment accuracy, and allows camera 5 to more quickly align with the glue outlet of needle assembly 21 of different sizes, ensuring monitoring effectiveness.

[0052] In this embodiment, there are four first arc-shaped holes 41, and correspondingly, there are four positioning holes 332. In other embodiments, the number of first arc-shaped holes 41 can also be two, three, five, etc., and the number of positioning holes 332 can also be two, three, five, etc., without specific limitations here.

[0053] In this embodiment, the first end of the guide fastener has an external thread, which forms a threaded connection with the internal thread of the corresponding positioning hole 332 on the movable end, realizing the detachable fixation of the guide fastener and the movable end; the second end of the guide fastener passes through the first arc hole 41 of the swing member 4, and a nut adapted to the external thread of the guide fastener is sleeved on the second end of the guide fastener. When the nut is tightened, the nut and the movable end apply clamping force from both sides of the swing member 4, so that the swing member 4 and the movable end fit tightly together, realizing reliable locking after the swing member 4 rotates; when the nut is loosened, the clamping force is released, and the swing member 4 can rotate smoothly along the arc direction of the first arc hole 41, ensuring the stability of the guide fastener installation. The tightness of the nut is used to realize the quick locking and unlocking of the swing member 4, which is convenient to operate and reliable in locking, and avoids the position displacement of the camera 5 during monitoring.

[0054] like Figures 1-2 As shown, the oscillating component 4 has a first angle scale (not shown) along the outer periphery of the first arc hole 41, with the center point of the dispensing port as the center. The movable end has a first indicator (not shown), the direction of which corresponds to the first angle scale. The first indicator is used to indicate the angle of rotation of the oscillating component 4 around the center point of the dispensing port. The first angle scale on the oscillating component 4, in conjunction with the first indicator on the movable end, can visually display the rotation angle of the oscillating component 4 around the center point of the dispensing port, allowing precise control of the rotation amplitude of the camera 5. After replacing the needle assembly 21 with different sizes, the optimal monitoring angle of the camera 5 can be quickly reproduced or adjusted according to the first angle scale, reducing repeated debugging time, improving the accuracy and consistency of adjustment, further optimizing the efficiency of the camera 5 aligning with the dispensing port, and ensuring the reliability of dispensing status monitoring.

[0055] like Figures 3-4As shown, the fixed end of the adjustment component 3 includes a support member 31, and the movable end includes a first slide 32 and a second slide 33. The support member 31 is connected to the frame 1, the first slide 32 is connected to the support member 31 and can slide or lock relative to the support member 31 in a first direction, and the second slide 33 is connected to the first slide 32 and can slide or lock relative to the first slide 32 in a second direction. The first slide 32 slides in the first direction, and the second slide 33 slides in the second direction, enabling precise adjustment of the camera 5 in two directions, further expanding the adjustment range of the camera 5, accommodating more sizes of needle assemblies 21, allowing the camera 5 to be aligned more quickly with the dispensing port of different needle assemblies 21, and simplifying the adjustment operation.

[0056] In this embodiment, the positioning hole 332 is provided on the second slide 33, and the guide fastener is directly connected to the second slide 33. When the second slide 33 slides and adjusts in the second direction, it can simultaneously drive the guide fastener, the swing member 4 and the camera 5 to move, ensuring that the cooperation between the guide fastener and the first arc hole 41 is stable during the adjustment process.

[0057] like Figure 4 As shown, the support member 31 is provided with a first groove 311 extending along a first direction, and the second slide 33 is provided with a second groove 331 extending along a second direction. The first slide 32 includes a first sliding part 321 extending along the first direction and a second sliding part 322 extending along the second direction. The first sliding part 321 is slidably engaged with the first groove 311, and the second sliding part 322 protrudes from the side of the first sliding part 321 facing the second slide 33 and is slidably engaged with the second groove 331. The first groove 311 of the support member 31 engages with the first sliding part 321 of the first slide 32, and the second groove 331 of the second slide 33 engages with the second sliding part 322 of the first slide 32. Through the interlocking structure of the groove and the sliding part, the guiding and stability of the first slide 32 sliding along the first direction and the second slide 33 sliding along the second direction are enhanced, avoiding deviation during sliding, ensuring accurate translation adjustment of the camera 5, allowing the dispensing port of the needle assembly 21 of different sizes to enter the field of view of the camera 5 more quickly, and improving the reliability of adjustment.

[0058] It is worth noting that the first slide 32 has a roughly cross-shaped structure. The first sliding part 321 and the second sliding part 322 are stably connected. When the first slide 32 moves relative to the support member 31 in the first direction, the first sliding part 321 slides along the first groove 311, driving the second sliding part 322 to slide. The second sliding part 322 is disposed in the second groove 331 to drive the second slide 33 to move synchronously in the first direction. That is, when the operator pushes the second slide 33 to move in the first direction, the second slide 33 and the first slide 32 move synchronously relative to the support member 31 in the first direction. When the second slide 33 moves in the second direction, since the second groove 331 and the second sliding part 322 slide in cooperation in the second direction, that is, when the operator pushes the second slide 33 to move in the second direction, the second slide 33 can slide independently relative to the first slide 32 in the second direction. This achieves smooth adjustment in both directions, improves the movement accuracy of the movable end driving the swing member 4 and the camera 5, and facilitates quick alignment with the dispensing ports of different needle assemblies 21.

[0059] like Figure 4 As shown, the adjustment assembly 3 also includes a first fastener 36 and a second fastener 37. The first fastener 36 is used to connect the second sliding part 322 of the support member 31 and the first slide 32 so that the position of the first slide 32 in the first direction can be locked. The second fastener 37 is used to connect the first sliding part 321 and the second slide 33 so that the position of the second slide 33 in the second direction can be locked. This ensures that the position of the camera 5 is stable after adjustment in the first and second directions. With the locking of the swing member 4, the stability of the camera 5 after it is aligned with the dispensing nozzle is ensured, and the reliability of monitoring the dispensing status of the needle assembly 21 is improved.

[0060] like Figure 4As shown, the adjustment assembly 3 also includes a first guide member 34 and a second guide member 35. The first guide member 34 includes a first guide sleeve portion 341 and a first guide post portion 342. The first guide sleeve portion 341 is connected to the support member 31, and the first guide post portion 342 is connected to the first slide table 32 and extends along a first direction. The first guide post portion 342 and the first guide sleeve portion 341 are slidably engaged. The second guide member 35 includes a second guide sleeve portion 351 and a second guide post portion 352. The second guide sleeve portion 351 is connected to the first slide table 32, and the second guide post portion 352 is connected to the second slide table 33 and extends along a second direction. The second guide post portion 352 and the second guide sleeve portion 351 are slidably engaged. The first guide member 34 cooperates with the first guide sleeve 341 and the first guide post 342 to provide precise guidance for the sliding of the first slide table 32 in the first direction; the second guide member 35 cooperates with the second guide sleeve 351 and the second guide post 352 to provide precise guidance for the sliding of the second slide table 33 in the second direction, enhances sliding stability, avoids deviation, and enables the movable end to drive the swing member 4 and the camera 5 to move smoothly. With the rotation adjustment of the swing member 4, the accuracy and efficiency of the camera 5 in aligning with the dispensing port of different needle components 21 are further improved, ensuring that the adjustment process is reliable and smooth.

[0061] Specifically, the first guide post 342 is connected to the second sliding part 322 and is disposed below the second sliding part 322; the second guide sleeve 351 is connected to the first sliding part 321 and is disposed to the side of the first sliding part 321.

[0062] like Figure 1 As shown, the dispensing device also includes a rotating shaft 6, which is connected to the frame 1. An adjusting component 3 is also connected to the rotating shaft 6. The rotating shaft 6 can rotate or lock relative to the frame 1 around the axis of the needle assembly 21. The rotating shaft 6, connected to the frame 1, can rotate or lock around the axis of the needle assembly 21. The adjusting component 3 is mounted on the rotating shaft 6 to drive the camera 5 to rotate around the axis of the needle assembly 21, further expanding the adjustment angle range, accommodating more sizes of needle assemblies 21, allowing the camera 5 to align with the dispensing nozzle more quickly, improving adjustment flexibility and adaptability, and ensuring comprehensive monitoring.

[0063] like Figure 1 and Figure 5 As shown, the dispensing mechanism 2 also includes a glue cylinder 22, which is connected to the frame 1. A needle assembly 21 is connected to the lower end of the glue cylinder 22 and communicates with it. The glue cylinder 22 can hold the glue, and the axis of the needle assembly 21 coincides with the axis of the glue cylinder 22. The glue contained in the glue cylinder 22 can be discharged through the needle assembly 21, which is connected to it. The axis of the needle assembly 21 coincides with the axis of the glue cylinder 22, so that the glue flows in a coaxial direction, reducing the resistance and residue caused by directional deviation during the transmission of the glue, allowing the glue to flow out stably and ensuring a stable dispensing state.

[0064] like Figure 1 and Figure 5 As shown, the dispensing device also includes a fastening clamp 9, which is an arched clamp. The first end of the arched clamp is rotatably connected to the frame 1, and the second end of the arched clamp is detachably fastened to the frame 1. The frame 1 is provided with an arc-shaped groove that can hold part of the glue tube 22. When the second end of the arched clamp is fastened to the frame 1, the glue tube 22 is locked in the area enclosed by the arched clamp and the arc-shaped groove, so that the glue tube 22 is fixedly connected to the frame 1. After the second end of the arched clamp is unfastened to the frame 1, the locking of the glue tube 22 is released, making it convenient to disassemble and replace the glue tube 22.

[0065] like Figure 1 and Figure 5 As shown, the needle assembly 21 includes a needle 211 and a connector 212. Both ends of the connector 212 are connected to the needle 211 and the glue cartridge 22, respectively. The lower end of the needle 211 is the glue outlet, ensuring a sealed and smooth glue delivery path. Optionally, the connector 212 is a Luer connector. The standardized structure of the Luer connector makes the connection between the needle 211 and the glue cartridge 22 tighter, facilitating easy installation and removal and providing good sealing, reducing the risk of glue leakage, improving the efficiency of replacing needles 211 of different specifications, facilitating stable control of the glue dispensing state, and enhancing the reliability and adaptability of the dispensing device.

[0066] like Figure 1 and Figure 5 As shown, the frame 1 has an annular boss 11 surrounding the rubber tube 22. The upper end of the rubber tube 22 passes through the annular boss 11, and the axis of the annular boss 11 is collinear with the axis of the rubber tube 22. The rotating shaft 6 has a clearance hole 62 that fits with the outer circumferential surface of the annular boss 11. The rotating shaft 6 can be fitted onto the annular boss 11 through the clearance hole 62, and the inner wall of the clearance hole 62 is rotatably connected to the outer circumferential surface of the annular boss 11, so that the rotating shaft 6 can rotate relative to the frame 1 around the axis of the needle assembly 21. The annular boss 11 of the frame 1 is rotatably connected to the inner wall of the clearance hole 62 of the rotating shaft 6, and the axis of the annular boss 11 is collinear with the axis of the rubber tube 22, so that the rotating shaft 6 can rotate smoothly around the axis of the needle assembly 21, providing a stable circumferential rotation basis for the adjustment assembly 3 and the camera 5.

[0067] In this embodiment, the dispensing device also includes a bearing. The inner ring of the bearing is connected to the outer peripheral surface of the annular boss 11, and the outer ring of the bearing is connected to the inner wall of the clearance hole 62, which greatly reduces the rotational resistance and makes the shaft rotating component 6 drive the camera 5 to rotate around the axis of the needle assembly 21 more smoothly and the adjustment efficiency is higher.

[0068] In this embodiment, the shaft rotating component 6 is also provided with a second arc hole 63. The axis of the second arc hole 63 is collinear with the axis of the annular boss 11. The fastener can pass through the second arc hole 63 and connect with the frame 1. After the shaft rotating component 6 rotates to a suitable position, the shaft rotating component 6 can be locked to ensure the circumferential position of the shaft rotating component 6, the adjustment component 3, the swing component 4 and the camera 5 is stable.

[0069] like Figure 1 and Figure 5 As shown, the rotating shaft 6 is provided with a second angle scale 61, the center of which is located on the axis of the needle assembly 21. The dispensing device also includes a second indicator 7 mounted on the frame 1. The direction of the second indicator 7 corresponds to the second angle scale 61. The second indicator 7 is used to indicate the angle of rotation of the rotating shaft 6 around the axis of the needle assembly 21. The second angle scale 61 of the rotating shaft 6 cooperates with the second indicator 7. The center of the second angle scale 61 is located on the axis of the needle assembly 21.
