Description

Technical Field

[0001] This utility model relates to the field of door and window technology, and in particular to a sash pressure line measuring device. Background Technology

[0002] In the manufacturing process of window sashes, the window sash frame is assembled first. Then, the sash trim profile is cut separately according to the measurement data. Finally, the trim is installed onto the window sash through pressing or gluing processes. This separate processing method can ensure higher precision and sealing performance. However, since the sash trim usually needs to be cut separately, inaccurate measurements can easily lead to mismatches with the window sash, seriously affecting the quality of the window sash.

[0003] Existing methods for measuring window sashes mainly rely on manual contact measurement or high-precision equipment, but most current technologies suffer from the following problems: First, it is inefficient. When using measuring tools, people need to measure window sashes of different sizes one by one, which delays the work speed.

[0004] Secondly, the operation is complex. Existing technologies in the field of fan-line measurement usually require frequent manual calibration, which carries a high risk of human error.

[0005] Therefore, there is a need for a fan pressure line measuring device that can quickly and accurately measure the fan pressure line. Utility Model Content

[0006] To address the technical problems existing in the background art, this utility model provides a fan pressure line measuring device.

[0007] The technical solution of this utility model is as follows: The fan pressure line measuring device includes a base, a gantry frame, and a fixing part; Several conveyor rollers are distributed from front to back on the upper surface of the base; The gantry frame is slidably mounted on the base in the front-to-back direction, and a measuring head is slidably mounted on it laterally. A height correction sensor and a size measurement sensor are installed below the measuring head. The fixing part includes several vertical stop rollers and clamping components. The vertical stop rollers are arranged vertically on the edge of the base at one end of the conveyor roller, and the clamping components are arranged inside part of the conveyor roller and connected to the base, which can push the object on the conveyor roller to be squeezed onto the vertical stop rollers.

[0008] The window sash enters the device from one side onto the conveyor rollers. The rollers, controlled automatically or manually, rotate to transport the sash between the first and second vertical stops at the exit end. A clamping mechanism, aided by a telescopic cylinder, pushes the sash against the vertical stops. The measuring head is adjusted and rotates around the sash, measuring the profile height using a height correction sensor for precise positioning. The dimensional measurement sensor, through the movement of the measuring head, accurately measures the sash around its perimeter, reducing measurement errors. After measurement, the conveyor rollers begin transporting the sash towards the exit side, and the measuring head returns to its initial position. The entire process is rapid and can be automatically adjusted according to different sash sizes, improving measurement efficiency.

[0009] Regarding the design of the measuring head, it includes a protective cover and a sliding component. The protective cover is slidably connected to the gantry frame, and the sliding component is vertically slidably connected inside the protective cover. A rotating shaft is installed inside the sliding component, and a sensor base is connected below the rotating shaft, allowing the sliding component to extend downwards. A height correction sensor and a dimension measurement sensor are fixed to the surface of the sensor base. A deceleration sensor is also installed inside the sliding component. The height correction sensor measures vertical distance, the dimension measurement sensor measures horizontal distance, and the deceleration sensor detects the passage of a window sash.

[0010] To facilitate measurement, the sensor base is an inverted L-shaped plate, with the vertical section coinciding with the axis of rotation, allowing for better fit to the shape of the window sash during measurement. The height correction sensor is fixed in the horizontal section, and the dimension measurement sensor is fixed in the vertical section. Both the height correction sensor and the dimension measurement sensor use laser sensors, which improves measurement accuracy and speed.

[0011] Regarding the design of the conveyor roller, it is a powered roller, and its conveying of window sashes is controlled by a servo.

[0012] Furthermore, the base is equipped with laser beam switches on both sides of the profile entry end and discharge detection switches on both sides of the profile exit end. The laser beam switches are used to detect the window sash entering, and the discharge detection switches are used to detect the window sash exiting.

[0013] Furthermore, a start button is provided on one side of the base, allowing manual / automatic selection via the control panel. When the window sash is placed within the conveying range, the start button can be pressed manually to rotate the conveyor rollers, at which point the laser beam switch detection is disabled. Alternatively, an automatic mode can be selected, where the laser beam switch detects the entry of the window sash, and the conveyor rollers transport the window sash.

[0014] Furthermore, the conveyor rollers can be made of rubber to increase conveying friction and prevent damage to the window sash.

[0015] Regarding the design of the deceleration sensor, when the deceleration sensor detects the window sash at the initial position of the measuring head, the servo control causes the conveyor roller to decelerate, so that the window sash eventually stops between the first and second vertical stop rollers on the discharge side.

[0016] Furthermore, the initial position of the measuring head is located near the second vertical stop at the discharge end. The specific position can be adjusted according to the specific debugging situation, with the reference being that the window sash can be stopped at an appropriate position between the first and second vertical stop.

[0017] Furthermore, the deceleration sensor can also be used as a predictive sensor for the height of the window sash profile, preventing the measuring head from being damaged during the initial measurement and positioning process due to incorrect profile height data.

[0018] Regarding the design of the clamping component, it includes a horizontal beam. One end of the horizontal beam is connected to the base, and the other end extends parallel to the axis of the conveyor roller. A sliding seat is connected to the bottom of the horizontal beam via a slide rail. The sliding seat slides along the length of the horizontal beam. A connecting plate is provided on the side of the sliding seat near the base. A vertical telescopic mechanism is connected to the end of the connecting plate near the base. The output end of the vertical telescopic mechanism is connected to a clamping component. The highest point of the clamping component is higher than the horizontal beam. A fixed seat is provided below the end of the horizontal beam. A first telescopic cylinder is horizontally mounted on the fixed seat, and the rod head of the first telescopic cylinder is connected to the connecting plate. By sliding the connecting plate driven by the sliding seat, the horizontal movement of the clamping component can be achieved, thereby allowing the clamping component to fix the window sash to one side of the vertical stop bar.

[0019] Furthermore, for larger and heavier door panels, the friction on the conveyor rollers is greater, and the telescopic cylinder may not be able to push them. The first telescopic cylinder can clamp the large window panel by hammering. The piston rod on the first telescopic cylinder reciprocates, causing the clamping element to repeatedly push the window panel, eventually allowing the heavier window panel to gradually approach and finally fit against the vertical stop bar.

[0020] Furthermore, the clamping component can adopt a long and narrow structure, which makes it easy to place between the conveyor rollers and avoid collisions with other components, thus preventing interference with the clamping motion.

[0021] Regarding the design of the connecting plate, it is parallel to the horizontal beam and includes a first connecting part and a second connecting part. One end of the first connecting part is located below the sliding seat, and the other end is vertically connected to the middle of the second connecting part. A vertical telescopic mechanism, which is a second telescopic cylinder, is located below the second connecting part, and the end of its piston rod is connected to the bottom of the clamping member. The piston rod of the second telescopic cylinder allows the clamping member to perform vertical reciprocating motion, which is flexible in use and also prevents the clamping member from obstructing the transmission of the window sash.

[0022] Regarding the design of the clamping component, it includes a first base plate connected to the end of the piston rod of the second telescopic cylinder. The long side of the first base plate is perpendicular to the long side of the horizontal beam, and the length of the first base plate is greater than the width of the horizontal beam. Guide shafts are vertically installed at both ends of the first base plate, passing through a second connecting part. A second base plate is installed at the top of the guide shafts, positioning the horizontal beam between the two guide shafts. The two guide shafts, the two base plates, and the second connecting part form multiple square structures, increasing the stability of the clamping component. The second base plate is always higher than the horizontal beam, and a clamping block is installed above it.

[0023] Regarding the design of the clamping block, it consists of a support section and a pressure plate. The support section is located on the upper surface of the second base plate, and the pressure plate is positioned on the side of the support section near the base. The side of the pressure plate near the base is flush with the side of the second base plate below it, or protrudes outward from the side to prevent the second base plate from contacting the window sash and thus avoiding wear on the window sash during clamping. Linear bearings are installed at the connection points between the two guide shafts and the second connecting section. The clamping action is achieved through the contact between the pressure plate and the edge of the window sash.

[0024] Furthermore, the pressure plate can be made of elastic material to avoid damaging the window sash.

[0025] Regarding the design of the vertical stop bar, the vertical stop bar is rotatably connected to the edge of the base, which can reduce friction during the transportation of the window sash and prevent wear and tear on the window sash and the vertical stop bar.

[0026] Through the above design, this utility model's sash pressing line measuring device allows the window sash to enter the conveyor roller from one side of the device. The conveyor roller is automatically or manually controlled to rotate, transporting the window sash between the first and second vertical stop rollers at the exit end. The deceleration sensor inside the measuring head can detect the window sash position to assist servo control of the transmission roller, and can also predict the height to prevent the measuring head from colliding with the window sash. The clamping component is generally square, providing structural stability. The clamping component moves horizontally and vertically via a telescopic cylinder. This saves space and allows for flexible adjustment when pushing different types of window sashes. The telescopic cylinder can also use a hammering action to ensure that heavier window sashes are pressed firmly against the vertical stop rollers, achieving a clamping effect.

[0027] The measuring head starts from its initial position, adjusts, and circles the window sash once, measuring the height of the profile using a height correction sensor and completing precise positioning. The dimensional measurement sensor, through the movement of the measuring head, accurately measures the perimeter of the window sash, reducing measurement errors and accelerating the measurement process. After measurement, the conveyor rollers transport the window sash towards the exit side, and the measuring head returns to its initial position. The entire process can be completed quickly and can be automatically adjusted according to different window sash sizes, improving measurement efficiency. Attached Figure Description

[0029] See Figures 1-6 As shown, this embodiment provides a fan pressure line measuring device, including a base 1, a gantry frame 2, and a fixing part.

[0030] Several conveyor rollers 4 are distributed from front to back on the upper surface of the base 1.

[0031] The gantry frame 2 is slidably mounted on the base 1 in the front-to-back direction, and the measuring head 3 is slidably mounted on it in the horizontal direction. A height correction sensor 31 and a size measuring sensor 32 are mounted below the measuring head 3.

[0032] The fixing part includes several vertical stop rollers 5 and clamping members 6. The vertical stop rollers 5 are arranged vertically on the edge of the base 1 at one end of the conveyor roller 4. The clamping members 6 are arranged inside part of the conveyor roller 4 and connected to the base 1, which can push the object on the conveyor roller 4 to be squeezed onto the vertical stop rollers 5.

[0033] The window sash enters the device from one side onto the conveyor roller 4. The conveyor roller 4 rotates automatically or manually, transporting the window sash between the first and second vertical stop rollers 5 at the exit end. The clamping member 6, using a telescopic cylinder, pushes the window sash against the vertical stop rollers 5, ensuring it is firmly against them. The measuring head 3 is adjusted and rotates around the window sash, measuring the profile height using the height correction sensor 31 and achieving precise positioning. The dimension measuring sensor 32 performs precise measurements around the window sash as the measuring head 3 moves, reducing measurement errors. After measurement, the conveyor roller 4 begins transporting the window sash towards the exit side, and the measuring head 3 returns to its initial position. The entire process can be completed quickly and can be automatically adjusted according to different window sash sizes, improving measurement efficiency.

[0034] Let's take a look at the specific design of each component: See Figure 1 The base 1 can be a hollow square frame, with a leveling base at the bottom to compensate for uneven ground. The conveyor roller 4 is a powered roller, with both ends mounted on the base 1. One end is connected to the adjacent conveyor roller 4 via a synchronous belt, and its rotation can be controlled by a servo. Laser beam switches 11 are installed on both sides of the window sash inlet end on the base 1, and discharge detection switches are installed on both sides of the window sash outlet end. The laser beam switches 11 detect the window sash entering, and the discharge detection switches detect the window sash exiting. The conveyor roller 4 stops conveying when the window sash leaves and until the discharge detection switches no longer detect the window sash.

[0035] As an improvement, a set of conveyor rollers can be configured on the discharge side of the equipment as a temporary storage area, and the initial position of the measuring head can be synchronized with the conveying of the window sash.

[0036] As another improvement, the discharge detection switch can consist of a laser emitter, a servo motor, and a reducer. After the laser emitter detects that the window sash has left, the reducer connected to the servo motor causes the conveyor roller 4 to decelerate and eventually stop.

[0037] Regarding the design of base 1, a cantilever extends outward from the outer edge of base 1 to avoid collision with any components. One end of the cantilever is provided with a corner and connected to base 1, while the other end is provided with a touch screen all-in-one machine and control buttons.

[0038] As an improvement to this utility model, the touch screen all-in-one machine is equipped with a keyboard and mouse, and the center line of the display can be approximately 1.5 meters above the ground. The touch screen all-in-one machine and some buttons are arranged in a cantilevered control box, and manual or automatic modes can be selected on the touch screen all-in-one machine.

[0039] As a further improvement of this utility model, a start button can be provided on one side of the base 1. In manual mode, when the window sash is placed into the conveying range, the start button can be pressed manually to make the conveying roller 4 rotate. At this time, the laser beam switch detection is invalid. Alternatively, an automatic mode can be selected, in which the entry of the window sash is detected by the laser beam switch, and the conveying roller 4 transports the window sash.

[0040] Regarding the design of the conveyor roller 4, this embodiment uses rubber material to increase the conveying friction and also avoid damage to the window sash.

[0041] Regarding the design of the vertical stop 5, the vertical stop 5 is rotatably connected to the edge of the base. When the window sash moves along the vertical stop 5, the vertical stop 5 will rotate to assist in transportation and reduce friction and wear.

[0042] Regarding the design of the gantry frame 2, it includes two uprights and a crossbeam. The two uprights are respectively set on both sides of the long side of the base 1, and the two ends of the crossbeam are set on the two uprights. The long side of the crossbeam is parallel to the axis of the conveyor roller. Guide rails are set on the long side of the base 1, and the two uprights are slidably set on the two guide rails respectively. The gantry frame 2 can be a dual servo system with gantry synchronization function.

[0043] See Figure 1 and Figure 6 Regarding the design of the measuring head, the measuring head 3 includes a protective cover and a sliding component. The protective cover is slidably connected to the gantry frame 2, and the sliding component is vertically slidably connected inside the protective cover. A rotating shaft is installed inside the sliding component, and a sensor base 34 is connected below the rotating shaft, allowing the sliding component to extend downwards. A height correction sensor 31 and a dimension measurement sensor 32 are fixed on the surface of the sensor base 34. A deceleration sensor 33 is also installed inside the sliding component. The height correction sensor 31 can measure vertical distance, the dimension measurement sensor 32 can measure horizontal distance, and the deceleration sensor 33 can detect the passage of the window sash.

[0044] To facilitate the measurement function, the sensor base 34 can be an inverted L-shaped plate, with the vertical section coinciding with the axis of rotation, allowing for better fit to the shape of the window sash during measurement. The height correction sensor 31 is fixed in the horizontal section, and the dimension measurement sensor 32 is fixed in the vertical section.

[0045] Preferably, both the height correction sensor 31 and the size measurement sensor 32 are laser sensors, which can improve the accuracy and speed of measurement.

[0046] In this invention, the measuring head 3 can be initially positioned at the starting measurement position. The sensor rotation center maintains an adjustable fixed distance from both sides of the window sash corners; specific data can be adjusted on-site. The height correction sensor 31 measures the profile height and completes precise positioning. The gantry frame 2 and the measuring head 3 work together to measure each side in a counter-clockwise sequence. Using the long side closest to the vertical stop 5 as a reference, the dimension measuring sensor 32 is positioned with the reference side, rotates 90 degrees, slides upwards, repeats three times, and then returns to the starting position to complete the measurement.

[0047] Regarding the design of the deceleration sensor 33, when the deceleration sensor 33 detects the window sash at the initial position of the measuring head 3, the servo control causes the conveyor roller 4 to decelerate, so that the window sash eventually stops between the first and second vertical stop rollers 5 on the discharge side.

[0048] Preferably, the deceleration sensor 33 can be a laser sensor, and the deceleration sensor 33 is disposed downward in the sliding member.

[0049] Furthermore, the initial position of the measuring head 3 is located near the second vertical stop 5 at the discharge end. The specific position can be adjusted according to the specific debugging situation, with the reference being that the window sash can be stopped at an appropriate position between the first and second vertical stop 5.

[0050] See Figure 2-5 Regarding the design of clamping component 6, clamping component 6 includes a horizontal beam 61. One end of the horizontal beam 61 is connected to the base 1, and the other end extends parallel to the axis of the conveyor roller 4. A sliding seat 66 is connected to the bottom of the horizontal beam 61 via a slide rail. The sliding seat 66 slides along the length of the horizontal beam 61. A connecting plate is provided at the bottom of the sliding seat 66, extending towards the base 1. A vertical telescopic mechanism is connected to the end of the connecting plate near the base 1. The output end of the vertical telescopic mechanism is connected to a clamping component. The highest end of the clamping component is higher than the horizontal beam 61. A fixed seat 62 is provided below the end of the horizontal beam 61. A first telescopic cylinder is horizontally mounted on the fixed seat 62, and the rod head of the first telescopic cylinder is connected to the bottom of the connecting plate. By sliding the connecting plate through the sliding seat 66, the horizontal movement of the clamping component can be realized, thereby allowing the clamping component to fix the window sash to one side of the vertical stop 5.

[0051] Furthermore, the fixed seat 62 adopts an inverted "L" shape, with its short side fixed below the horizontal beam, and a first telescopic cylinder set on the long side away from the base 1. The center part of the telescopic cylinder passes through the fixed seat 62 to connect with the piston rod. The upper surface of the sliding seat 66 is slidably connected to the slide rail, and the lower surface is fixedly connected to the connecting plate.

[0052] As a further improvement, for a door panel with large size and heavy weight, the friction force on the conveying roller 4 is relatively large, which may cause the telescopic cylinder to be unable to push. The first telescopic cylinder can realize the clamping of a large window panel through a hammering action. The piston rod on the first telescopic cylinder drives the clamping member to repeatedly push the window panel through reciprocating motion, so that the heavier window panel can gradually get closer and finally fit against the vertical stop rod 5.

[0053] In this embodiment, the overall horizontal cross beam 61 can adopt a long strip structure, the part fixed on the base 1 is a square with a wider width, and bolts are used on the square to fix the horizontal cross beam 61 on the edge of the base 1. The overall clamping member 6 can adopt a long and narrow structure, which is convenient to be arranged between the conveying rollers 4 and can avoid collision with other components that affects the progress of the clamping movement.

[0054] Regarding the design of the connecting plate, the connecting plate can be parallel to the horizontal cross beam 61. The connecting plate includes a first connecting part and a second connecting part. One end of the first connecting part is arranged below the sliding seat 66, and the other end is vertically connected to the middle of the second connecting part. A vertical telescopic mechanism is arranged below the second connecting part, the vertical telescopic mechanism is a second telescopic cylinder, and the end of its piston rod is connected to the bottom of the pressing member. In this embodiment, the telescopic cylinder can be an air cylinder.

[0055] Preferably, both the first connecting part and the second connecting part can adopt a square plate structure, and the two are vertically combined to form a "convex" shape. A connecting shaft is vertically arranged below the first connecting part, and the piston rod head of the first telescopic cylinder is connected with a shaft end bearing, which is sleeved on the connecting shaft to realize the connection between the first telescopic cylinder and the connecting plate.

[0056] Regarding the design of the pressing member, the pressing member includes a first bottom plate, the first bottom plate is connected to the end of the piston rod of the second telescopic cylinder, the long side of the first bottom plate is perpendicular to the long side of the horizontal cross beam 61, and the length of the first bottom plate is greater than the width of the horizontal cross beam 61. Guide shafts 63 are vertically arranged at both ends of the first bottom plate, two guide shafts 63 pass through the second connecting part, and a second bottom plate is arranged at the top ends thereof, so that the horizontal cross beam 61 is located between the two guide shafts 63, and linear bearings are arranged at the connecting parts of the two guide shafts 63 and the second connecting part. The second bottom plate is always higher than the horizontal cross beam 61, and a pressing block is arranged above it.

[0057] Regarding the design of the pressing block, the pressing block is divided into a supporting part 64 and a pressing plate 65, the supporting part 64 is located on the upper surface of the second bottom plate, the pressing plate 65 is arranged on the side of the supporting part 64 close to the base 1, the side of the pressing plate 65 close to the base 1 is flush with the side surface of the second bottom plate below it, or protrudes outward from the side surface, so as to prevent the second bottom plate from contacting the window panel and avoid wearing the window panel during the clamping process. The clamping action is performed through the contact between the pressing plate and the edge of the window panel.

[0058] Furthermore, the support 64 can be a rectangular block located in the middle of the second base plate on the side away from the base 1, and its shape is consistent with that of the pressure plate 65. The two are connected by bolts.

[0059] As an improvement, the pressure plate 65 is made of elastic material to avoid damaging the window sash.

[0060] In this invention, the operator places the window sash at the feed side, ensuring it is flush against the vertical stop bar 5. After the window sash is conveyed to the designated position, the piston rod in the second telescopic cylinder rises, and the guide shaft 63 drives the clamping component to rise vertically. The piston rod of the first telescopic cylinder pushes the clamping component to move towards the base 1, causing the pressure plate 65 to contact the window sash, thus completing the clamping motion.
