Description

Technical Field

[0001] This utility model belongs to the field of visual measurement, and in particular relates to an inspection calibration plate installation device for textile workshops. Background Technology

[0002] In the textile production process of spandex and other yarn materials, faults such as reverse winding, broken yarn, and tangled yarn are prone to occur. In textile workshops, special inspection personnel are usually arranged to continuously inspect various equipment to check and deal with faults. Manual inspection is inefficient and costly, and the workshop environment is not friendly to the health of the inspection personnel.

[0003] Currently, inspection robots are used to replace manual inspections. The robot's vision system photographs and identifies equipment on the textile production line for yarn materials. To facilitate the measurement of the spatial position and geometric dimensions of the equipment, the robot's vision system needs to be calibrated. A common method is to install a calibration plate on the equipment.

[0004] The calibration plate is a flat plate with a fixed-spaced pattern array used to correct lens distortion and determine the conversion relationship between physical dimensions and pixels. It is generally a glass plate and is fixed to one side of the equipment by a mounting frame. During the production of spandex yarn, it needs to be impregnated with oil. Even slight disturbances during high-speed transmission can cause vibrations in the spandex yarn, easily causing the oil adhering to it to be flung out, forming small droplets suspended in the air. This results in a large amount of oil mist in the textile workshop, which then adheres to surrounding objects, such as the calibration plate. After prolonged production, the oil adhering to the surface of the calibration plate slowly flows downwards and accumulates on the lower edge of the mounting frame, forming a large oil sludge between the lower edge of the mounting frame and the calibration plate. When the inspection robot's vision system takes pictures, this oil sludge will cause abnormal reflections, thus affecting the normal inspection work of the inspection robot. Utility Model Content

[0005] The purpose of this utility model is to provide an inspection calibration plate installation device for textile workshops, so as to solve the technical problem that the lower side frame of the mounting frame used to install the calibration plate in the prior art is prone to accumulating a lot of oil stains, which causes abnormal reflection when the inspection robot takes pictures and affects the normal operation of the inspection robot.

[0006] To achieve the above objectives, the technical solution of the inspection calibration plate installation device for textile workshops provided by this utility model is as follows:

[0007] A calibration plate installation device for textile workshops includes a mounting base with mounting holes for mounting onto equipment. The back of the mounting base has a mounting groove for embedding the calibration plate. The front of the mounting base has a window for exposing the calibration identification area of ​​the calibration plate. The lower sidewall of the window has a converging structure that is high at both ends and low in the middle. The lowest point of the lower sidewall of the window has an oil collection trough for collecting oil. The oil collection trough extends forward and / or backward through the mounting base so that the oil in the oil collection trough can flow forward and / or backward.

[0008] As a further improvement, a confluence ramp is provided between the end and the lowest point of the middle of the lower sidewall of the window to guide the oil sludge flow to the oil collection tank.

[0009] As a further improvement, a guide channel for draining oil is provided between the lower side wall of the mounting groove and the lower side surface of the mounting base, and the rear end of the oil collection groove corresponds to and is connected to one of the guide channels.

[0010] As a further improvement, the sidewall of the flow channel and the sidewall of the mounting groove are rounded.

[0011] As a further improvement, flow channels are provided at both ends of the lower side wall of the mounting groove.

[0012] As a further improvement, the mounting base is provided with at least two mounting holes, and each mounting hole is provided with a positioning ring protruding from the back surface of the mounting base. The inner hole of the positioning ring is coaxial with the mounting hole and can allow fasteners to pass through. The positioning ring is used to be inserted into the countersunk hole on the equipment and to pre-position the mounting base during installation.

[0013] As a further improvement, the mounting base is provided with at least two positioning protrusions protruding from the back surface of the mounting base. The positioning protrusions have positioning surfaces for fitting against the side of the equipment or the side wall of the equipment's oil filling hole. The positioning surfaces on the at least two positioning protrusions are perpendicular to each other, and the height of the positioning protrusions is greater than the height of the positioning ring.

[0014] As a further improvement, an external positioning protrusion is provided at the edge of the mounting base, protruding from the back surface of the mounting base. The external positioning protrusion is used to fit against the side of the equipment to pre-position the mounting base during installation.

[0015] As a further improvement, the mounting base is provided with an inner positioning protrusion protruding from the back surface of the mounting base. The inner positioning protrusion is used to fit against the side wall of the oil filling hole on the front of the equipment to pre-position the base during installation.

[0016] As a further improvement, the mounting base is provided with at least two positioning protrusions protruding from the back surface of the mounting base. The positioning protrusions have positioning surfaces for fitting against the side of the equipment or the sidewall of the oil filling hole of the equipment, and the positioning surfaces on the at least two positioning protrusions are perpendicular to each other.

[0017] The beneficial effects are as follows: The inspection calibration plate installation device for textile workshops provided by this utility model is an improvement on the existing technology. This installation device has a confluence structure on the lower side wall of the window of the mounting base that guides oil stains from both ends towards the center, and an oil collection trough at the lowest point of the lower side wall of the window that collects the oil stains. During use, the oil stains on the calibration plate flow downwards to the surface of the lower side wall of the window, and are then guided by the confluence structure into the oil collection trough, where they are discharged forward or backward, preventing oil stains from accumulating on the lower side wall of the window and affecting the inspection robot's photography.

[0023] The present invention will be further described in detail below with reference to the embodiments.

[0024] Specific Embodiment 1 of the Inspection and Calibration Plate Installation Device for Textile Workshops Provided by This Utility Model:

[0025] See appendix Figure 1 and attached Figure 2The inspection calibration plate mounting device used in this textile workshop is used to fix the calibration plate 4 onto the equipment on the textile production line. This equipment is specifically an oil-immersing device, with an oil replenishment hole 3 on its front for adding oil. The oil-immersing device includes a main housing 1 and an end cap 2 bolted to the front end of the main housing 1. The end cap 2 closes the front end of the main housing 1, and the oil replenishment hole 3 is located on the end cap 2. During production, spandex yarns enter from one side of the oil-immersing device and exit from the other side.

[0026] The calibration plate 4 is installed on the front of the oil-immersion equipment using a calibration plate mounting device for inspection in textile workshops, so that the inspection robot can take pictures.

[0027] See appendix Figure 3 The inspection calibration plate installation device used in the textile workshop includes a mounting base 5, which has mounting holes 6 for mounting onto the equipment. The back of the mounting base 5 has a mounting groove 7 for embedding the calibration plate 4, and the front of the mounting base 5 has a window 8 for exposing the calibration identification area of ​​the calibration plate 4.

[0028] The central area of ​​calibration plate 4 is a calibration identification area with a calibration identification pattern, while the edge area of ​​calibration plate 4 has no calibration identification pattern. Calibration plate 4 is inserted into mounting groove 7 from back to front, with the calibration identification area exposed from window 8. After calibration plate 4 is inserted into mounting groove 7, the back side of calibration plate 4 is flush with the back side of mounting base 5. After mounting base 5 is installed on oil immersion equipment, the back side of calibration plate 4 is limited by the front side of oil immersion equipment, and the edge area of ​​the front side of calibration plate 4 is limited by the bottom of mounting groove 7, thereby achieving fixed installation of calibration plate 4.

[0029] The main housing 1 of the oil immersion equipment has threaded holes, and the end cover 2 has countersunk holes corresponding to the threaded holes for installing bolts. The mounting base 5 has two mounting holes 6, and the positions of these two mounting holes 6 correspond to the positions of two countersunk holes on the end cover 2. This allows the original bolts to be passed through the mounting holes 6, then through the countersunk holes, and finally screwed into the threaded holes, thus simultaneously fixing the mounting base 5, end cover 2, and main housing 1 together. This method fully utilizes the existing structure of the end cover 2, eliminating the need for additional holes on the end cover 2 to install the inspection calibration plate 4 mounting device used in the textile workshop, facilitating the modification of existing equipment.

[0030] On the back side of the mounting base 5, a positioning ring 10 protruding from the back surface of the mounting base 5 is provided at each mounting hole 6. The inner hole of the positioning ring 10 is coaxial with the mounting hole 6 and has the same size, so that the positioning ring 10 can also be passed through by bolts. During the installation process, the positioning ring 10 is first inserted into the countersunk hole on the end cover 2 to achieve pre-positioning of the mounting base 5, which facilitates the subsequent bolt installation operation.

[0031] In addition to the positioning ring 10, the mounting base 5 is also provided with positioning protrusions to pre-position the mounting base 5. The positioning protrusions all protrude from the back surface of the mounting base 5, and each positioning protrusion has a positioning surface that can fit against the side of the oil immersion equipment or against the side wall of the oil replenishment hole 3 to achieve pre-positioning during installation.

[0032] The positioning protrusions include an outer positioning protrusion 11 and an inner positioning protrusion 12. The outer positioning protrusion 11 is located at the left edge of the mounting base 5, and the positioning surface on the outer positioning protrusion 11 can fit against the left side of the oil immersion equipment. The inner positioning protrusion 12 is located at the upper edge of the mounting base 5, and the inner positioning protrusion 12 can fit against the lower wall of the oil replenishment hole 3.

[0033] The outer positioning protrusion 11 and the inner positioning protrusion 12 are higher than the positioning ring sleeve 10. This allows for initial positioning before the positioning ring sleeve 10 is inserted into the countersunk hole of the end cap 2, followed by secondary positioning using the positioning ring sleeve 10. The positioning surfaces on the outer positioning protrusion 11 and the inner positioning protrusion 12 are perpendicular to each other. The outer positioning protrusion 11 and the inner positioning protrusion 12 are sufficient to accurately position the mounting base 5, facilitating the alignment and insertion of the positioning ring sleeve 10 into the countersunk hole of the end cap 2. Furthermore, the positioning surfaces on the positioning protrusions can slide against the corresponding surfaces on the oil-immersing equipment, thus enabling quick initial positioning by the installer. After initial positioning, the mounting base 5 is pushed to insert the positioning ring sleeve 10 into the countersunk hole of the end cap 2. At this point, the mounting base 5 can remain temporarily stable without manual support, facilitating bolt installation.

[0034] The mounting base 5 has a notch structure 13 at its corner to indicate the installation direction, preventing installers from accidentally installing the mounting base 5 in the wrong direction. The notch structure 13 is located on the upper end of the side of the mounting base 5 away from the outer positioning protrusion 11. In other embodiments, the notch structure 13 can also be located in other positions, or an indicator mark and pattern can be provided on the mounting base 5 to replace the notch structure 13 in indicating the installation direction.

[0035] The lower sidewall of window 8 has a confluence structure that is high at both ends and low in the middle. At the lowest point of the lower sidewall of window 8, there is an oil collection trough 15 for collecting oil stains. The oil collection trough 15 extends forward through the front side of the mounting base 5 and backward through the bottom wall of the mounting groove 7. Oil stains adhering to the front of the calibration plate 4 can flow downwards under gravity. When they reach the lower sidewall of window 8, they can flow into the oil collection trough 15 under the guidance of the confluence structure. Once the oil stains in the oil collection trough 15 have accumulated to a certain amount, they can flow out forward or backward along the trough 15. This prevents excessive oil stain accumulation above the lower sidewall of window 8, avoiding large oil stains that could cause abnormal reflections when the inspection robot takes pictures, thus ensuring the normal operation of the inspection robot.

[0036] The lower sidewall of window 8 includes two converging ramps 14, which guide the oil sludge downwards to the oil collection tank 15 from the left and right ends of the lower sidewall of window 8, respectively. In other embodiments, the converging structure may not be the converging ramps 14, but rather the surface of the lower sidewall of window 8 may be set as an arc-shaped surface, with the lowest point of the arc-shaped surface located in the middle, which can also serve the function of converging.

[0037] A flow guide channel is provided between the lower wall of the mounting groove 7 and the lower surface of the mounting base 5. In this embodiment, the flow guide channel is a flow guide trough 9, and three flow guide troughs 9 are provided, located at the middle, left end, and right end of the mounting groove 7, respectively. The flow guide trough 9 located in the middle corresponds to the position of the oil collection groove 15 and is connected to the rear end of the oil collection groove 15. The oil in the oil collection groove 15 can flow backward and enter the flow guide trough 9, and finally be discharged directly downward along the flow guide trough 9. A guiding arc angle is provided between the side wall of the flow guide trough 9 and the side wall of the mounting groove 7 to make the flow of oil more smooth and improve the efficiency of oil discharge.

[0038] The guide grooves 9 located at both ends provide more paths for oil to drain, preventing excessive oil buildup between the calibration plate 4 and the side or bottom walls of the mounting groove 7, thus aiding in oil drainage. Additionally, the guide grooves 9 at both ends also avoid the sharp corners of the calibration plate 4, preventing damage during installation and use. The mounting base 5 has separate avoidance grooves 16 at positions corresponding to the two sharp corners on the upper part of the calibration plate 4 to prevent damage to those corners.

[0039] In other embodiments of this implementation, the guide groove 9 may be provided only once, corresponding to the oil collection groove 15, and the left and right ends of the lower side wall of the mounting groove 7 may be provided only with avoidance grooves 16 to avoid the two sharp corners of the lower part of the calibration plate 4.

[0040] By placing the flow guide 9 on the back side of the mounting base 5, the flow guide 9 and mounting groove 7 can be machined in one go on the back side of the mounting base 5, which improves processing efficiency and keeps the front side of the mounting base 5 flat, resulting in a better aesthetic appearance. In other embodiments, the flow guide 9 can also be machined on the front side of the mounting base 5, or the flow guide 9 can be omitted, and the oil will flow directly from the oil collection tank 15 to the front side of the mounting base 5.

[0041] In other embodiments of this implementation, a screw can be fixedly installed on the oil immersion equipment. During installation, the mounting hole 6 is fitted onto the screw, and then a nut is installed on the screw to fix the mounting device.

[0042] In other embodiments of this implementation, the mounting device can also be fixedly mounted on the oil-immersing equipment by welding.

[0043] In other embodiments of this implementation, the mounting device can also be installed on other equipment on the textile production line that requires inspection.

[0044] In other embodiments of this implementation, the flow channel may also be a flow guide hole.
