Description

Technical Field

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

[0002] In the dispensing process, the vertical distance between the dispensing head's outlet and the product is crucial. If the dispensing head's outlet is too close or too far from the product, an ideal dispensing shape cannot be obtained, reducing the dispensing quality.

[0003] In related technologies, to ensure dispensing quality, the product height needs to be measured before dispensing, and then the position of the dispensing head is adjusted vertically. The optimal dispensing height relative to the product is determined by manually adjusting the vertical height of the dispensing head, and a distance sensor is used to detect the specific height. However, this specific height is the vertical distance between the distance sensor's detection end and the product, not the vertical height of the dispensing head relative to the product. In short, there is an error in the vertical direction between the dispensing head and the distance sensor. The data obtained from the distance sensor cannot be quantified into the actual vertical distance between the dispensing head and the product. This error in the vertical direction prevents effective closed-loop analysis of the theoretical relationship between adhesive viscosity, glue valve orifice size, dispensing pressure, and dispensing height.

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

By fixing a distance detection component to the dispensing head, the distance detection component detects the vertical distance between its detection end and the upper surface of the calibration base.

By using an imaging component to capture images of the dispensing head and the calibration base in the horizontal direction, and using a reading component connected to the imaging component to read the captured images, the vertical distance D between the dispensing head outlet and the upper surface of the calibration base can be obtained. The vertical distance K = LD between the detection end of the distance sensor and the dispensing head's outlet is determined. After obtaining the specific value of K, due to the mutual fixation between the dispensing head and the distance sensor, the value of L measured by the distance sensor will continuously change as the dispensing head moves relative to the product during subsequent dispensing operations. Using LK, the actual value of the vertical distance between the dispensing head's outlet and the product can be obtained. Based on the actual value of the vertical distance between the dispensing head's outlet and the product, a closed-loop analysis can be performed to determine the theoretical relationship between glue viscosity, glue valve orifice size, dispensing pressure, and dispensing height, thus ensuring the quality of dispensing the product.

[0060] 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.

[0061] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0062] 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.

[0063] 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.

[0064] In the dispensing process, the vertical distance between the dispensing head's outlet and the product is crucial. If the outlet is too close or too far, an ideal dispensing shape cannot be achieved, reducing dispensing quality. To ensure quality, the product's height must be measured before dispensing, and then the dispensing head's position is adjusted vertically. The optimal dispensing height is determined manually by continuously adjusting the vertical height of the dispensing head relative to the product, and a distance sensor is used to detect this height. However, this height is the vertical distance between the distance sensor's detection end and the product, not the vertical height of the dispensing head relative to the product. In short, there is an error in the vertical direction between the dispensing head and the distance sensor. The data from the distance sensor cannot be quantified into the actual vertical distance between the dispensing head and the product. This error in the vertical direction prevents effective closed-loop analysis of the theoretical relationship between adhesive viscosity, valve orifice size, dispensing pressure, and dispensing height.

[0065] To solve the above problems, such as Figures 1-4 As shown, this embodiment provides a dispensing height detection device to accurately detect the vertical distance between the dispensing head 2000 and the surface of the product to be processed. The dispensing height detection device includes a calibration base 200, a distance detection element 300, an imaging component 100, and a reading component. The calibration base 200 is disposed below the dispensing head 2000. The distance detection element 300 is fixed to the dispensing head 2000 and is used to detect the vertical distance between its detection end and the upper surface of the calibration base 200. The imaging component 100 is configured to capture images of the dispensing head 2000 and the calibration base 200 in a horizontal direction. The reading component is communicatively connected to the imaging component 100 and can read the images captured by the imaging component 100 and measure the vertical distance between the dispensing head 2000's outlet and the upper surface of the calibration base 200.

[0066] This dispensing height detection device simulates the relative positional relationship between the dispensing head 2000 and the product by setting a calibration base 200 below the dispensing head 2000. By fixing a distance detection element 300 to the dispensing head 2000, the distance detection element 300 detects the vertical distance between its detection end and the upper surface of the calibration base 200, thus obtaining the vertical distance L between the detection end of the distance detection element 300 and the upper surface of the calibration base 200. By using an imaging component 100 to capture images of the dispensing head 2000 and the calibration base 200 horizontally, and using a reading component communicatively connected to the imaging component 100 to read the captured images, the vertical distance L between the dispensing head 2000's outlet and the upper surface of the calibration base 200 is obtained. By determining the distance D, the vertical distance K = LD between the detection end of the distance detection component 300 and the dispensing port of the dispensing head 2000 can be obtained. After obtaining the specific value of K, since the dispensing head 2000 and the distance detection component 300 are fixed to each other, the value of L measured by the distance detection component 300 will continuously change as the dispensing head 2000 moves relative to the product during the subsequent dispensing operation. Using LK, the actual value of the vertical distance between the dispensing port of the dispensing head 2000 and the product can be obtained. Based on the actual value of the vertical distance between the dispensing port of the dispensing head 2000 and the product, a closed-loop analysis can be performed on the theoretical relationship between glue viscosity, glue valve orifice size, dispensing pressure and dispensing height to ensure the dispensing quality of the product.

[0067] Optionally, the dispensing height detection device further includes a first support base 700, a second support base 800, and a third support base 900. The first support base 700 supports the imaging component 100, the second support base 800 supports the calibration base 200, and the third support base 900 supports the dispensing head 2000. By setting the first support base 700 to support the imaging component 100, the second support base 800 to support the calibration base 200, and the third support base 900 to support the dispensing head 2000, the positional requirements of the imaging component 100 in the horizontal direction for detecting the dispensing head 2000 and the calibration base 200 can be met.

[0068] In an optional embodiment, the dispensing height detection device further includes a three-axis drive structure. A portion of the three-axis drive structure is installed between the first support 700 and the imaging component 100, while another portion is installed between the second support 800 and the calibration base 200. The three-axis drive structure can adjust the relative position between the calibration base 200 and the imaging component 100 in the left-right, front-back, and up-down directions, respectively. By adjusting the relative position between the calibration base 200 and the imaging component 100 in the left-right, front-back, and up-down directions, the focal length of the imaging component 100 can be adjusted to ensure effective imaging of the dispensing head 2000 and the calibration base 200 by the imaging component 100.

[0069] In this embodiment, the three-axis drive structure includes a left-right drive assembly 400, a front-rear drive assembly 500, and a vertical drive assembly 600. The left-right drive assembly 400 is mounted on a first support 700, and its output is connected to the imaging assembly 100. The left-right drive assembly 400 can drive the calibration base 200 to move in the left-right direction relative to the imaging assembly 100. The output of the vertical drive assembly 600 is connected to the calibration base 200, and it can drive the calibration base 200 to move in the vertical direction. The front-rear drive assembly 500 is mounted on a second support 800, and its output is connected to the vertical drive assembly 600. The front-rear drive assembly 500 can drive the vertical drive assembly 600 to move in the front-rear direction relative to the imaging assembly 100. By installing a left-right drive assembly 400 on the first support 700 and connecting the shooting assembly 100 to the output of the left-right drive assembly 400, the shooting assembly 100 is driven to move in the left-right direction relative to the calibration base 200. By installing a front-back drive assembly 500 on the second support 800 and connecting the output of the front-back drive assembly 500 to the up-down drive assembly 600, the calibration base 200 is connected to the output of the up-down drive assembly 600, thus achieving the effect of driving the calibration base 200 to move in the front-back and up-down directions relative to the shooting assembly 100.

[0070] It should be noted that in other embodiments, the connection relationship between the three sets of structures of the left and right drive component 400, the front and rear drive component 500 and the up and down drive component 600 and the shooting component 100 and the calibration base 200 can also be adjusted according to actual needs, as long as it can drive the shooting component 100 to move relative to the calibration base 200 in the left and right direction, the front and rear direction and the up and down direction. This embodiment does not make specific limitations.

[0071] Combination Figure 5The specific structure of the left and right drive assembly 400 is described below. The left and right drive assembly 400 includes a first fixed member 410, a first movable member 420, a first drive member 430, and a first elastic reset member (not shown in the figure). The first fixed member 410 is mounted on the first support base 700. The first movable member 420 slides with the first fixed member 410 in the left and right direction. The shooting assembly 100 is mounted on the first movable member 420. The first fixed member 410 has a first through-part, and the first movable member 420 has a first abutting part. The first through-part and the first abutting part are arranged sequentially in the left and right direction. The first drive member 430 passes through the first through-part in the left and right direction and abuts against the first abutting part. The first drive member 430 can drive the first abutting part to move in the left and right direction relative to the first through-part. The first elastic reset member extends in the left and right direction. One axial end of the first elastic reset member is fixed to the first through-part, and the other axial end of the first elastic reset member is fixed to the first abutting part. The first elastic reset member can generate elastic deformation in the left and right direction.

[0072] By fixing the first fixing member 410 to the first support base 700 and providing a first movable member 420 that slides and engages with the first fixing member 410 in the left-right direction, a first through-hole portion is provided in the first fixing member 410, and a first abutting portion is provided in the first movable member 420, so that the first through-hole portion and the first abutting portion are arranged sequentially in the left-right direction, and the first driving member 430 passes through the first through-hole portion and abuts against the first abutting portion, the effect of the first driving member 430 driving the first movable member 420 to move away from the first fixing member 410 in the left-right direction can be achieved. The first elastic reset member disposed between the first through part and the first abutment part is stretched by force when the first driving member 430 drives the first movable member 420 away from the first fixed member 410 in the left and right direction. When the first driving member 430 removes the driving force on the first abutment part and no longer abuts the first abutment part, the first elastic reset member can use its own elastic force to drive the first movable member 420 to move and reset relative to the first fixed member 410, thereby achieving the effect of driving the first movable member 420 to move freely in the left and right direction relative to the first fixed member 410.

[0073] It should be noted that in this embodiment, the first elastic reset element is a spring. Springs have a simple structure, are small in size, and are easy to assemble and disassemble. In other embodiments, the first elastic reset element may also be a rubber block or other structures capable of elastic deformation; this embodiment does not impose specific limitations.

[0074] Alternatively, either the first fixed member 410 or the first movable member 420 may be provided with at least one first guide rail, and the other may be provided with at least one first guide slider. The first guide rails extend in a left-right direction, and each first guide rail slides in contact with at least one guide slider. By providing at least one guide slider in either the first fixed member 410 or the first movable member 420, and providing at least one guide slider in the other, each guide rail slides in contact with at least one guide slider, thus providing guidance for the movement of the first movable member 420 relative to the first fixed member 410.

[0075] It should be noted that, in this embodiment, the first fixing member 410 is provided with two first guide slide rails arranged side by side in the front-back direction, and both first guide slide rails extend in the left-right direction. The first movable member 420 is provided with two first guide sliders arranged side by side in the front-back direction, and each first guide slide rail slides in slidable engagement with one first guide slider. In other embodiments, the first guide slide rails can also be provided on the first movable member 420 and the first guide sliders can be provided on the first fixing member 410. The specific number of first guide slide rails and first guide sliders can also be adjusted according to actual needs, as long as each first guide slide rail slides in slidable engagement with at least one first guide slider. This embodiment does not impose specific limitations.

[0076] Furthermore, in this embodiment, the first through-part has a first threaded through-hole extending in the left-right direction, and the outer peripheral wall of the first driving member 430 along the axial direction is provided with an external thread that threadedly engages with the first threaded through-hole. After the first driving member 430 passes through the first threaded through-hole, it abuts against the first abutting part. By providing a first threaded through-hole extending in the left-right direction in the first through-part, the first driving member 430 passes through the first threaded through-hole and abuts against the first abutting part. The thread drives the first driving member 430 to move in the left-right direction, thereby improving the accuracy of the left-right movement of the first driving member 430. When it is necessary to drive the first driving member 430 to move to the left relative to the first fixed member 410, the first driving member 430 is driven to rotate in the forward direction around its own axis. When it is necessary to drive the first driving member 430 to move to the right relative to the first fixed member 410, the first driving member 430 is driven to rotate in the reverse direction around its own axis.

[0077] Optionally, the front and rear drive assembly 500 includes a second fixed member 510, a second movable member 520, a second drive member 530, and a second elastic reset member (not shown in the figure). The second fixed member 510 is mounted on the second support base 800, the second movable member 520 slides with the second fixed member 510 in the front-rear direction, the upper and lower drive assembly 600 is mounted on the second movable member 520, the second fixed member 510 has a second through portion, the second movable member 520 has a second abutting portion, the second through portion and the second abutting portion are arranged sequentially in the front-rear direction, the second drive member 530 passes through the second through portion in the front-rear direction and abuts against the second abutting portion, the second drive member 530 can drive the second abutting portion to move relative to the second through portion in the front-rear direction, the second elastic reset member extends in the front-rear direction, one axial end of the second elastic reset member is fixed to the second through portion, the other axial end of the second elastic reset member is fixed to the second abutting portion, and the second elastic reset member can generate elastic deformation in the front-rear direction.

[0078] By fixing the second fixing member 510 to the second support base 800 and providing a second movable member 520 that slides and engages with the second fixing member 510 in the left-right direction, a second through-part is provided inside the second fixing member 510, and a second abutting part is provided inside the second movable member 520, so that the second through-part and the second abutting part are arranged sequentially in the front-back direction, and the second driving member 530 passes through the second through-part and abuts against the second abutting part, the effect of the second driving member 530 driving the second movable member 520 to move away from the second fixing member 510 in the front-back direction can be achieved. The second elastic reset member disposed between the second through part and the second abutment part is stretched under force when the second driving member 530 drives the second movable member 520 away from the second fixed member 510 in the front-back direction. When the second driving member 530 removes the driving force on the second abutment part and no longer abuts against the second abutment part, the second elastic reset member can use its own elastic force to drive the second movable member 520 to move and reset relative to the second fixed member 510, thereby achieving the effect of driving the second movable member 520 to move freely relative to the second fixed member 510 in the front-back direction.

[0079] Similarly, the up-down drive assembly 600 includes a third fixed member 610, a third movable member 620, a third drive member 630, and a third elastic reset member. The third fixed member 610 is fixed to the second movable member 520, and the third movable member 620 and the third fixed member 610 slide in the up-down direction. The calibration base 200 is mounted on the third movable member 620. The third fixed member 610 has a third through part, and the third movable member 620 has a third abutting part. The third through part and the third abutting part are arranged sequentially in the up-down direction. The third drive member 630 passes through the third through part in the up-down direction and abuts against the third abutting part. The third drive member 630 can drive the third abutting part to move in the up-down direction relative to the third through part. The third elastic reset member extends in the up-down direction. One axial end of the third elastic reset member is fixed to the third through part, and the other axial end of the third elastic reset member is fixed to the third abutting part. The third elastic reset member can generate elastic deformation in the up-down direction.

[0080] In this embodiment, the front and rear drive assembly 500 is provided with a second guide slide rail and a second guide slider, and the upper and lower drive assembly 600 is provided with a third guide slide rail and a third guide slider. Moreover, the connection method between the second drive member 530 and the second through part and the connection direction between the third drive member 630 and the third through part are the same as the connection method between the first drive member 430 and the first through part. For the sake of simplicity, they will not be described in detail here.

[0081] In one of the alternative solutions, such as Figure 5 As shown, the imaging assembly 100 includes a camera 110, which is disposed on one side of the calibration base 200 along the horizontal direction. The camera 110 is fixed to the first movable member 420, and is configured to capture images of the dotted head 2000 and the calibration base 200 in the horizontal direction. It should be noted that in this embodiment, the camera 110 is a CCD camera. CCD cameras have a simple structure and high imaging accuracy.
