Abstract
Description
Technical Field
[0001] This utility model relates to the field of measuring equipment for flexible touch screen switches in home appliances, and more specifically, it relates to a workbench device for measuring flexible touch screen switches in home appliances. Background Technology
[0002] Existing flexible touch screen switches for home appliances need to be precisely matched with the mounting slots and internal brackets of the appliance casing to avoid dimensional deviations. Otherwise, the correspondence between the touch area and the circuit will be affected. Therefore, dimensional measurement of flexible touch screen switches for home appliances is a key step to ensure their performance, reliability, assembly compatibility and user experience.
[0003] In existing image measuring instruments, the workpiece is typically placed on a platform during measurement. The platform moves horizontally along the X and Y axes, while the automatic image measuring instrument's lifting device moves along the Z axis. When the workpiece is smaller than the surface area of the platform, it can be placed directly without operator intervention. However, if the workpiece is larger than the platform, a complete measurement cannot be performed, requiring manual movement of the workpiece to move any unmeasured portions to the top of the platform. This manual operation can easily cause workpiece positional shifts, negatively impacting the measurement process.
[0004] Therefore, a new solution is needed to address this problem. Utility Model Content
[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a workbench device for measuring flexible touch screen switches of home appliances in order to solve the above-mentioned problems.
[0006] This utility model achieves the above-mentioned objective through the following technical solution: a workbench device for measuring flexible touch screen switches in home appliances, comprising a workbench body, wherein the workbench body is provided with a movable positioning device, the movable positioning device comprising: Positioning clamps are used to hold and fix flexible touch screen switches of home appliances; A guide rail assembly is used to guide the sliding direction of the positioning fixture. The guide rail assembly is fixedly mounted on the worktable body, and the positioning fixture is slidably mounted on the worktable body through the guide rail assembly. A coordinate anchor point assembly is used to mark the measurement position of a flexible touch screen switch in a home appliance. The coordinate anchor point assembly is connected to a positioning fixture. When the positioning fixture moves the flexible touch screen switch of the home appliance through the guide rail assembly, and the coordinate anchor point assembly moves synchronously with the positioning fixture, the boundary point between the measured and unmeasured parts can be determined after the flexible touch screen switch of the home appliance is moved.
[0007] The present invention is further configured such that the coordinate anchor point component includes: An identification element, bearing user-identifiable features, is slidably connected to a positioning fixture; A positioning element is used to fix the position of the marker on the positioning fixture. An elastic element is provided between the positioning element and the marker. The elastic element is used to push the positioning element to abut against the positioning fixture. The end of the positioning element away from the positioning fixture extends to the outside of the marker.
[0008] The present invention is further configured such that: a movable rod is fixedly connected to the positioning fixture, and the marker is slidably disposed on the movable rod.
[0009] The present invention is further configured such that the positioning fixture includes: The base is fixedly connected to the guide rail assembly; A workpiece locking component is used to detachably fix a flexible touch screen switch of a home appliance onto a positioning fixture. The workpiece locking component is rotatably mounted on a base, and a torsion spring is provided between the workpiece locking component and the base to push the workpiece locking component against the flexible touch screen switch of the home appliance.
[0010] The present invention is further configured such that the guide rail assembly includes: The guide rail base is fixedly installed on the main body of the worktable; A sliding rod is slidably mounted on a guide rail seat, and one end of the sliding rod is fixedly connected to a positioning fixture.
[0011] The present invention is further configured such that: the guide rail assembly further includes a limiting block, the limiting block is slidably disposed on the sliding rod, and an elastic pad is provided between the limiting block and the sliding rod for pushing one end of the limiting block to abut against the side wall of the guide rail seat; After the sliding rod is displaced, the limiting block abuts against the side wall of the guide rail seat to fix the position of the sliding rod on the guide rail seat after the displacement.
[0012] Compared with the prior art, the beneficial effects of this utility model are: Firstly, the positioning fixture achieves linear constraint on the workpiece movement trajectory through the precise sliding fit of the guide rail assembly and the controllable elastic force of the workpiece locking component, avoiding positional deviation caused by manual movement and ensuring measurement accuracy. Secondly, the markers on the coordinate anchor point assembly can be flexibly adjusted along the moving rod, and in conjunction with the initial coordinate recording function, segmented measurement of workpieces exceeding platform dimensions can be achieved. By associating the positions of the coordinate anchor points, data splicing errors in different local areas can be reduced, and repeated measurements can be minimized. Attached Figure Description

Example
[0016] A workbench device for measuring flexible touchscreen switches in household appliances, such as Figures 1-3 As shown, the device includes a workbench body 1, which is equipped with a movable positioning device. The movable positioning device includes a positioning fixture 2 for clamping and fixing a flexible touch screen switch for home appliances, and a guide rail assembly 3 for guiding the sliding direction of the positioning fixture 2. The guide rail assembly 3 is fixedly mounted on the workbench body 1, and the positioning fixture 2 is slidably mounted on the workbench body 1 via the guide rail assembly 3. This allows the positioning fixture 2 to slide stably when the size of the flexible touch screen switch is larger than the surface area of the workbench body 1 and cannot be fully measured. This avoids the problem that existing manual operations can easily cause the flexible touch screen switch to shift its position, which can adversely affect the measurement of the workpiece.
[0017] At the same time, such as Figures 1-3As shown, it also includes a coordinate anchor point component 4 for marking the measurement position of the flexible touch screen switch of the home appliance. The coordinate anchor point component 4 is connected to the positioning fixture 2, so that when the positioning fixture 2 moves the flexible touch screen switch of the home appliance through the guide rail component 3, the coordinate anchor point component 4 also moves synchronously. Thus, after the flexible touch screen switch of the home appliance moves, the boundary point between the measured part and the unmeasured part can be determined by the coordinate anchor point component 4, providing an operational basis for the subsequent splicing of measurement data of each local area.
[0018] The main body 1 of the workbench has a clamping plate (not shown) that is detached and fixed on the side away from the positioning fixture 2 by a magnet. After the flexible touch screen switch of the home appliance is fixedly connected to the positioning fixture 2 and laid flat, the clamping plate is placed on the flexible touch screen switch of the home appliance to fix the position of the other side of the measurement area of the flexible touch screen switch of the home appliance.
[0019] like Figures 2-3 As shown, the coordinate anchor point assembly 4 includes an identifier 7 with user-identifiable features and a positioning element 8 for fixing the position of the identifier 7 on the positioning fixture 2. The identifier 7 is slidably connected to the positioning fixture 2, so that the user can adjust the relative position between the identifier 7 and the positioning fixture 2 according to the measurement range of the image measuring instrument. After the position is determined, the positioning element 8 fixes its position.
[0020] Among them, such as Figure 3 As shown, an elastic element 9 is provided between the positioning element 8 and the marking element 7. The elastic element 9 is used to push the positioning element 8 to abut against the positioning clamp 2. The end of the positioning element 8 away from the positioning clamp 2 extends to the outside of the marking element 7. The positioning effect of the positioning element 8 is achieved by the elastic support force of the elastic element 9. When it is necessary to release the fixation, it is only necessary to pull the positioning element 8 outward, thereby compressing the elastic element 9 away from the positioning clamp 2 to achieve the fixation release.
[0021] The elastic element 9 is made of spring, which provides good elastic support for the elastic element 9.
[0022] like Figures 2-3 As shown, a movable rod 10 is fixedly connected to the positioning fixture 2, and the marker 7 is slidably disposed on the movable rod 10. By increasing the sliding range of the marker 7 through the movable rod 10, the number of local area splits can be reduced, and the measurement efficiency and accuracy can be improved. Furthermore, the positioning element 8 abuts against the outer wall of the movable rod 10, thereby adjusting the position of the marker 7 on the movable rod 10 by controlling the connection and separation of the positioning element 8 and the movable rod 10.
[0023] like Figure 1As shown, the positioning fixture 2 includes a base 11 fixedly connected to the guide rail assembly 3 and a workpiece locking member 12 for detachably fixing the flexible touch screen switch of the home appliance onto the positioning fixture 2. The workpiece locking member 12 is rotatably mounted on the base 11, and a torsion spring (not shown) is provided between the workpiece locking member 12 and the base 11 to push the workpiece locking member 12 against the flexible touch screen switch of the home appliance. Thus, when the flexible touch screen switch of the home appliance to be measured is fixed on the positioning fixture 2, the spring force of the torsion spring can be overcome by moving the workpiece locking member 12. The spring force of the torsion spring is set to 5-10N to ensure that the flexible touch screen switch of the home appliance has no obvious deformation and the displacement relative to the positioning fixture 2 is ≤0.01mm, taking into account both the reliability of the fixation and the protection of the flexible material.
[0024] like Figures 1-3 As shown, the guide rail assembly 3 includes a guide rail seat 5 fixedly installed on the worktable body 1 and a sliding rod 6 slidably set on the guide rail seat 5. One end of the sliding rod 6 is fixedly connected to the positioning fixture 2. Thus, the sliding rod 6 and the guide rail seat 5 are engaged by a precision ball slider, with a straightness error ≤0.01mm / 100mm, thereby controlling the sliding direction and position of the positioning fixture 2 and avoiding deviation from affecting the measurement.
[0025] Among them, such as Figures 2-3 As shown, the guide rail assembly 3 also includes a limiting block 13, which is slidably mounted on the sliding rod 6. An elastic pad 14 is provided between the limiting block 13 and the sliding rod 6 to continuously push one end of the limiting block 13 against the side wall of the guide rail seat 5. Thus, through the cooperation of the limiting block 13 and the elastic pad 14, the block is fixed in position on the guide rail seat 5. This allows for real-time positioning when the user adjusts the position of the positioning clamp 2. The elastic pad 14 is an airbag, inflated to 101325 Pascals, ensuring that the preload of the limiting block 13 embedded in the slot is stable at 8-15 N.
[0026] Working principle: Step 1: Fix the flexible touch screen switch of the home appliance to be measured onto the positioning fixture 2, ensuring that the flexible touch screen switch of the home appliance is stationary relative to the positioning fixture 2; Step 2: Then pull the positioning piece 8 outward, thereby separating the positioning piece 8 from the moving rod 10, releasing the position fixation of the marker piece 7, and then move the position of the marker piece 7 so that the marker piece 7 moves to the boundary of the measurement area of the image measuring instrument. Then remove the external force on the positioning piece 8, the position of the positioning piece 8 is reset, and the position of the marker piece 7 is fixed, thereby determining the measurement range of the area. Then start the image measuring instrument to perform the measurement, and measure the first area of the flexible touch screen switch of the home appliance through the image measuring instrument. Step 3: After the image measuring instrument completes the measurement of the first local area, the base 11 of the sliding positioning fixture 2 moves outward, thereby moving the second local area of the flexible touch screen switch of the home appliance into the detection field of view. At the same time, when the base 11 moves, the moving rod 10 drives the marker 7 to move together, so that the measurement boundary of the first local area can be determined by the marker 7, and then the positional relationship between the second local area and the first local area can be determined. Then, when the image measuring instrument is positioned before measuring the second local area, the initial position can be confirmed by the marker 7. Then, the second step is repeated to determine the measurement range of the second local area. Then, the image measuring instrument is started to measure the second area of the flexible touch screen switch of the home appliance. Step 4: Repeat step 3 until all areas of the flexible touch screen switch of the home appliance are measured. The measurement data of each local area are spliced by associating the position of the coordinate anchor point component 4.
