Description

Technical Field

[0001] This application relates to the field of glass surface treatment performance testing equipment, and in particular to a testing device and method for the anti-abrasion performance of glass screen printing. Background Technology

[0002] Induction cookers are widely used in modern kitchens due to their high efficiency, safety, and ease of cleaning. Their control panels are typically made of high-strength microcrystalline glass or crystallized glass, and the surface is screen-printed to indicate heating zones, function buttons, and other information.

[0003] When conducting abrasion tests on crystallized glass, a reciprocating friction method is usually used. The testing equipment drives the friction head to move linearly back and forth on the surface of the glass sample fixed on the platform through a drive unit.

[0004] The aforementioned equipment has a relatively simple structure and can perform standardized testing. However, its significant drawback lies in its singular motion trajectory, which can only simulate the linear dragging of the cookware and cannot realistically reproduce the curved sliding that occurs during actual use. Consequently, the test results deviate significantly from the actual wear conditions, making the evaluation of the wear resistance of the screen printing on the glass panel of the induction cooker insufficiently comprehensive and accurate.

[0005] In other words, existing technologies have the following technical problems: ordinary testing equipment is unable to simulate curved friction trajectories. Therefore, a testing device for the anti-wear performance of glass screen printing is proposed to address the above problems. Summary of the Invention

[0019] This application also provides a testing method for a testing device based on the abrasion resistance performance of glass screen printing, the testing method comprising the following steps:

[0020] a. Equipment preparation and initial setup;

[0021] First, place the glass plate in the area of ​​the processing platform and ensure that the test area is flat and unobstructed. If the glass plate is lightweight or has a smooth surface, the glass fixing assembly needs to be operated: the screw is driven by rotating the knob on the support plate frame to press down, so that the rubber pressure plate at the bottom is pressed against the side of the glass plate to prevent displacement during the test.

[0022] b. Installation and counterweight of the frying pan;

[0023] Select a test pan and embed its bottom into the circular placement groove of the pan fixing component, ensuring that the pan edge is locked into the upper edge of the groove; then turn the handle to move the downward screw downward, using the top of the screw to press against the inner wall of the pan to achieve a tight fixation; after fixing, add counterweights to the pan to simulate the load during cooking, according to the test requirements.

[0024] c. Adjustment of curvilinear motion parameters;

[0025] Operate according to the type of adjustment unit configured in the device: For screw drive mode, the rotating turntable drives the bevel gear set in conjunction, causing the screw to push the moving rod to adjust the position of the contact roller; for bolt positioning mode, first loosen the locking bolt, manually slide the moving rod to the target concave hole position, and then re-tighten it; for ratchet locking mode, pull up the unlocking rod to disengage the pawl, slide the moving rod, and then release the pawl to achieve self-locking; adjust the distance between the contact roller and the convex plate through the above operations to control the curvilinear motion amplitude, or completely separate the two to switch to a pure linear test mode;

[0026] d. Test parameter settings;

[0027] Set the operating parameters of the reciprocating linear drive unit: precisely set the travel distance to 10 cm, adjust the drive frequency so that the pan moves back and forth once every 2 seconds, and preset the total number of counter tests to 800 reciprocating cycles to ensure that the test conditions meet the standard requirements.

[0028] e. Start-up testing and motion control;

[0029] The reciprocating linear drive unit is activated, driving the U-shaped connecting frame to move the legs along the fixed guide rail to perform linear reciprocating motion; if the curve simulation function is enabled, the convex plate fixed to the first connecting arm contacts the roller during linear movement, and its arc or trapezoidal convex pushes the transverse slide to compress the connecting spring, causing the first connecting arm to produce transverse displacement, and then drives the pan to form a "linear + transverse" composite motion trajectory on the glass surface through the second connecting arm, thereby simulating the curved friction state of the pan bottom.

[0030] f. Monitoring the testing process;

[0031] Throughout the test, the movement trajectory of the pan was continuously observed to verify whether the curve amplitude met the preset value, while ensuring that the glass plate did not shift. At the same time, the operating status of the drive unit was observed and monitored to ensure the stability of the stroke, frequency and counting. If any abnormality occurred, the machine was stopped immediately for troubleshooting.

[0032] g. Test termination and result determination;

[0033] After 800 rounds of testing, the equipment will automatically stop. The glass plate will be removed and placed under a light source to determine whether it is qualified. If there are only slight scratches on the surface that are difficult to see with the naked eye, it is considered qualified. If there are any obvious linear scratches or flaking damage that are white, it is considered unqualified.

[0034] In order to solve the problem that in the prior art, ordinary glass abrasion resistance testing equipment cannot fully simulate the actual frictional movement of the pot bottom on the glass panel when testing crystallized glass for induction cookers using simple linear drag friction, this application designs a curve movement control component. By setting the curve movement control component, curve movement simulation can be achieved under the premise of linear reciprocating drag friction, and the curve movement amplitude can be flexibly adjusted, thereby fully simulating the curve movement of the pot bottom on the glass panel. At the same time, no additional power control equipment is required, making it simple to use and easy to operate, and it is particularly suitable for abrasion resistance testing of crystallized glass for induction cookers.

[0059] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0060] The microcrystalline glass involved in this application is an advanced inorganic non-metallic material. The testing device and testing method provided in this application are used to test the new material.

[0061] Please see Figure 1-3 As shown, a testing device for the abrasion resistance of glass screen printing is provided, the testing device comprising:

[0062] A processing platform 1 is provided, and a reciprocating linear drive unit 2 is fixedly connected to the upper surface of the processing platform 1. One end of the reciprocating linear drive unit 2 is connected to the frying pan 5 and is used to drive the frying pan 5 to move reciprocally in a linear manner.

[0063] A guide moving component 3 is disposed between the reciprocating linear drive unit 2 and the frying pan 5. The guide moving component 3 is composed of a linear guide unit and a transverse guide unit. A first connecting arm 306 is fixedly connected to the transverse guide unit. A second connecting arm 307 is rotatably connected to one end of the first connecting arm 306. A frying pan fixing component 4 is rotatably connected to one end of the second connecting arm 307. The frying pan fixing component 4 is used to connect and fix the frying pan 5.

[0064] The curve movement control component 6 consists of a protruding plate 601 fixed to the side wall of the first connecting arm 306 and an adjustment structure fixed to the surface of the processing platform 1. One end of the adjustment structure is fixedly installed with a contact roller 602, which is used to contact the protruding plate 601.

[0065] To address the problem that existing glass abrasion resistance testing equipment cannot adequately simulate the actual frictional movement of the pot bottom on the glass panel when testing crystallized glass for induction cookers using simple linear drag friction, this application designs a curved movement control component 6. By setting up the curved movement control component 6, curved movement simulation can be achieved under the premise of linear reciprocating drag friction, and the amplitude of the curved movement can be flexibly adjusted, thus fully simulating the curved movement of the pot bottom on the glass panel. Furthermore, no additional power control equipment is required, making it simple to use and easy to operate, and it is particularly suitable for abrasion resistance testing of crystallized glass for induction cookers.

[0066] As a further technical solution, the reciprocating linear drive unit 2 is an electric cylinder, which can be selected as an electric push rod, an electric hydraulic cylinder, or a ball screw device, etc., for linear mobile equipment.

[0067] For specific technical solutions, please refer to Figure 4 and Figure 5 As shown, the linear guide unit includes a fixed guide rail 301 and a slide block 302. There are two fixed guide rails 301, which are fixed in parallel on the upper surface of the processing platform 1. The slide block 302 is slidably connected to the fixed guide rail 301.

[0068] The lateral guide unit includes a leg 303, a fixed guide rod 304, and a lateral slide 305. Two legs 303 are provided, each fixed to the upper surface of one slide 302. Two fixed guide rods 304 are fixedly connected between the two legs 303. The fixed guide rods 304 pass through the lateral slide 305 and slide in cooperation with it. One end of a connecting spring 308 is fixedly connected to the side wall of the lateral slide 305, and the other end of the connecting spring 308 is fixedly connected to the side wall of the leg 303. A U-shaped connecting frame 309 is fixedly connected between the two legs 303 for connecting to one end of the reciprocating linear drive unit 2. Through this technical solution, the operation of the reciprocating linear drive unit 2 can drive the U-shaped connecting frame 309 to move, thereby driving the legs 303 to move, causing the legs 303 to reciprocate linearly along the fixed guide rail 301, achieving the guiding function of linear movement.

[0069] For further technical solutions, please refer to Figure 13 As shown, the pan fixing assembly 4 consists of a circular placement groove 401 and a pressing screw 403. The outer wall of the circular placement groove 401 is rotatably connected to one end of the second connecting arm 307. Several L-shaped fixing plates 402 are fixedly connected to the arc-shaped wall of the circular placement groove 401. The pressing screw 403 is threaded onto the L-shaped fixing plate 402. A handle 404 is fixedly connected to the top of the pressing screw 403. With this technical solution, during testing, a stainless steel, iron, or aluminum alloy pan can be selected. The pan 5 is placed inside the circular placement groove 401, with the protruding part of the upper edge of the pan 5 engaging with the upper edge of the circular placement groove 401. Rotating the handle 404 causes the pressing screw 403 to rotate and press down, pressing it firmly against the inner wall of the pan 5, thus achieving the fixing function. Simultaneously, a counterweight can be placed inside the pan 5 to simulate the weight of the food, thereby improving the realism of the test and making it more closely resemble friction operations in real-world scenarios.

[0070] For specific technical solutions, please refer to Figure 5 and Figure 6As shown, the adjustment structure of the curve movement control component 6 consists of a rectangular fixed rod 604 and a rectangular moving rod 605 fixed to the upper end of the fixed base 603. The rectangular fixed rod 604 has an internal sliding groove cavity, and the rectangular moving rod 605 is slidably connected within the cavity of the rectangular fixed rod 604. A contact roller 602 is installed at the front end of the rectangular moving rod 605, and the contact roller 602 contacts the side of the convex plate 601. An adjustment part is also provided on the rectangular fixed rod 604, which is used to adjust the extension distance of the rectangular moving rod 605. Through this technical solution, the contact roller 602... 2. In cooperation with the convex plate 601, when the first connecting arm 306 moves linearly, it drives the convex plate 601 to move linearly synchronously. When the convex plate 601 contacts the contact roller 602, it can push the first connecting arm 306 to move laterally by squeezing. At the same time, the connecting spring 308 is compressed, which can make the convex plate 601 always move in close contact with the contact roller 602. During the linear movement, it drives the first connecting arm 306 to move laterally, thereby driving the frying pan 5 to move laterally. The combination of lateral movement and linear movement makes the frying pan 5 move along a curved trajectory, realizing the function of curve friction test.

[0071] Simultaneously, the adjustment unit can adjust the position of the contact roller 602. By adjusting, the contact roller 602 can be moved closer to the convex plate 601 or away from the convex plate 601. When the contact roller 602 is close to the convex plate 601, the lateral displacement distance of the convex plate 601 is greater, resulting in a greater lateral displacement distance of the pan 5 and a larger curve amplitude. When the contact roller 602 is away from the convex plate 601, the lateral displacement distance of the convex plate 601 is smaller, resulting in a smaller curve amplitude. When the contact roller 602 is completely away from the convex plate 601 and does not contact the convex plate 601, the convex plate 601 does not move laterally and only performs a linear friction test.

[0072] Example 1 of the regulating section:

[0073] Please see Figure 7As shown, the adjusting part includes a turntable 606, a first bevel gear 607, and a drive screw 608. The rectangular moving rod 605 has an internal cavity, and a threaded sleeve 610 is fixedly connected to the internal cavity of the rectangular moving rod 605. The drive screw 608 is rotatably connected to the side wall of the internal cavity of the rectangular fixed rod 604. The drive screw 608 passes through the threaded sleeve 610 and is threadedly engaged with the threaded sleeve 610. A second bevel gear 609 is fixedly connected to the arc-shaped wall of the drive screw 608. A turntable 606 is disposed on the outer surface of a rectangular fixed rod 604 and is rotatably connected to the rectangular fixed rod 604. A first bevel gear 607 is fixedly connected to the bottom end of the turntable 606. The first bevel gear 607 and the second bevel gear 609 mesh with each other. Through this technical solution, manually rotating the turntable 606 drives the first bevel gear 607 to rotate, drives the second bevel gear 609 to rotate, drives the drive screw 608 to rotate, thereby driving the threaded sleeve 610 to move, realizing the position adjustment function of the contact roller 602.

[0074] Example 2 of the regulating section:

[0075] Please see Figure 8 As shown, the adjusting part consists of recessed holes 611 on the surface of a rectangular moving rod 605 and locking bolts 612 on a rectangular fixed rod 604. Several recessed holes 611 are provided, equidistantly spaced on the surface of the rectangular moving rod 605. Locking bolts 612 are threaded onto the rectangular fixed rod 604, with the bottom end of each locking bolt entering the recessed hole 611. This technical solution achieves locking and fixing through the cooperation of the locking bolts 612 and the recessed holes 611. When position adjustment is required, the locking bolts 612 can be loosened first, and then the rectangular moving rod 605 can be manually moved to adjust the position. After adjustment, the locking bolts 612 are tightened to re-lock them within the recessed holes 611 for fixation.

[0076] Example 3 of the regulating section:

[0077] Please see Figure 9 and Figure 10As shown, the adjustment part consists of a ratchet 613 mounted on a rectangular moving rod 605 and a pawl 617 mounted on a rectangular fixed rod 604. A groove is formed on the surface of the rectangular moving rod 605, and several equally spaced ratchet 613s are formed at the groove positions. A fixed housing 614 is fixedly connected to the outer surface of the rectangular fixed rod 604. A guide slider 615 is slidably connected to the inner cavity of the fixed housing 614. A pawl 617 is fixedly connected to the bottom surface of the guide slider 615, and the bottom end of the pawl 617 extends into the tooth groove of the ratchet 613. An unlocking rod 616 is fixedly connected to the upper surface of the guide slider 615. The guide slider 615 passes through the upper wall of its inner cavity and extends to the outside of the wall. One end of a limiting spring 618 is fixedly connected to the upper surface of the guide slider 615. The other end of the limiting spring 618 is fixedly connected to the inner wall of the fixed shell 614. With this technical solution, due to the cooperation of the pawl 617 and the ratchet 613, when adjustment is needed, the rectangular moving rod 605 can be manually stretched to move and adjust the position. At the same time, the pawl 617 and the ratchet 613 can achieve reverse self-locking. When unlocking is needed, the unlocking rod 616 can be manually pulled to drive the guide slider 615 to move, so that the pawl 617 moves and separates from the ratchet 613, thereby unlocking and pushing the rectangular moving rod 605 to retract.

[0078] Example 1 of the convex plate 601:

[0079] Please see Figure 11 As shown, the convex plate 601 includes a plate body 6011 and arc-shaped protrusions 6012, and the plate body 6011 is provided with a plurality of arc-shaped protrusions 6012 arranged at equal intervals.

[0080] Example 2 of the convex plate 601:

[0081] Please see Figure 12 As shown, the convex plate 601 includes a plate body 6011 and trapezoidal protrusions 6013, and a plurality of trapezoidal protrusions 6013 are arranged at equal intervals on the plate body 6011.

[0082] For further details, please refer to Figure 14As shown, a glass fixing assembly 8 is also provided on the side of the processing platform 1. The glass fixing assembly 8 includes a support plate frame 801, a screw 802, and a rubber pressure plate 804. The support plate frame 801 is fixedly installed on the side wall of the processing platform 1. The screw 802 is threadedly connected to the support plate frame 801. A knob 803 is fixedly connected to the upper end of the screw 802, and a rubber pressure plate 804 is fixedly connected to the bottom end of the screw 802. With this technical solution, when testing a lightweight, smooth glass plate 7, manually rotating the knob 803 moves the screw 802 downward, causing the rubber pressure plate 804 to press against the side of the glass plate 7, preventing test deviation.

[0083] The test method for the abrasion resistance of the glass screen printing includes the following steps:

[0084] The test method for the abrasion resistance of the glass screen printing includes the following steps:

[0085] a. Equipment preparation and initial setup;

[0086] First, place the glass plate in the area of ​​the processing platform and ensure that the test area is flat and unobstructed. If the glass plate is lightweight or has a smooth surface, the glass fixing assembly needs to be operated: the screw is driven by rotating the knob on the support plate frame to press down, so that the rubber pressure plate at the bottom is pressed against the side of the glass plate to prevent displacement during the test.

[0087] b. Installation and counterweight of the frying pan;

[0088] Select a test pan and embed its bottom into the circular placement groove of the pan fixing component, ensuring that the pan edge is tightly locked into the upper edge of the groove; then turn the handle to move the downward screw downward, using the top of the screw to press against the inner wall of the pan to achieve a tight fixation; after fixing, add counterweights to the pan according to the test requirements to simulate the load during cooking.

[0089] c. Adjustment of curvilinear motion parameters;

[0090] Operate according to the type of adjustment unit configured in the device: For screw drive mode, the rotating turntable drives the bevel gear set in linkage, causing the screw to push the moving rod to adjust the position of the contact roller; for bolt positioning mode, first loosen the locking bolt, manually slide the moving rod to the target concave hole position, and then re-tighten it; for ratchet locking mode, pull up the unlocking rod to disengage the pawl, slide the moving rod, and then release the pawl to achieve self-locking; adjust the distance between the contact roller and the convex plate through the above operations to control the curvilinear motion amplitude, or completely separate the two to switch to a pure linear test mode.

[0091] d. Test parameter settings;

[0092] Set the operating parameters of the reciprocating linear drive unit: precisely set the travel distance to 10 cm, adjust the drive frequency so that the pan moves back and forth once every 2 seconds, and preset the total number of counter tests to 800 reciprocating cycles to ensure that the test conditions meet the standard requirements.

[0093] e. Start-up testing and motion control;

[0094] The reciprocating linear drive unit is activated, driving the U-shaped connecting frame to move the legs along the fixed guide rail to perform linear reciprocating motion. If the curve simulation function is enabled, the convex plate fixed to the first connecting arm contacts the roller during linear movement. Its arc or trapezoidal convexity pushes the transverse slide to compress the connecting spring, causing the first connecting arm to produce transverse displacement. Then, through the second connecting arm, the pan is driven to form a "linear + transverse" composite motion trajectory on the glass surface, realizing the simulation of the curved friction state of the pan bottom.

[0095] f. Monitoring the testing process;

[0096] Throughout the test, the movement trajectory of the pan was continuously observed to verify whether the curve amplitude met the preset value, while ensuring that the glass plate did not shift. At the same time, the operating status of the drive unit was observed to ensure the stability of the stroke, frequency and counting. If any abnormality occurred, the machine was stopped immediately for troubleshooting.

[0097] g. Test termination and result determination;

8. A test method based on the test apparatus for the abrasion resistance of glass screen printing according to any one of claims 1-7, characterized in that: The testing method includes the following steps: a. Equipment preparation and initial setup; First, place the glass plate in the area of ​​the processing platform and ensure that the test area is flat and unobstructed. If the glass plate is lightweight or has a smooth surface, the glass fixing assembly needs to be operated: the screw is driven by rotating the knob on the support plate frame to press down, so that the rubber pressure plate at the bottom is pressed against the side of the glass plate to prevent displacement during the test. b. Installation and counterweight of the frying pan; Select a test pan and embed its bottom into the circular placement groove of the pan fixing component, ensuring that the pan edge is locked into the upper edge of the groove; then turn the handle to move the downward screw downward, using the top of the screw to press against the inner wall of the pan to achieve a tight fixation; after fixing, add counterweights to the pan to simulate the load during cooking, according to the test requirements. c. Adjustment of curvilinear motion parameters; Operate according to the type of adjustment unit configured in the device: For screw drive mode, the rotating turntable drives the bevel gear set in conjunction, causing the screw to push the moving rod to adjust the position of the contact roller; for bolt positioning mode, first loosen the locking bolt, manually slide the moving rod to the target concave hole position, and then re-tighten it; for ratchet locking mode, pull up the unlocking rod to disengage the pawl, slide the moving rod, and then release the pawl to achieve self-locking; adjust the distance between the contact roller and the convex plate through the above operations to control the curvilinear motion amplitude, or completely separate the two to switch to a pure linear test mode; d. Test parameter settings; Set the operating parameters of the reciprocating linear drive unit: precisely set the travel distance to 10 cm, adjust the drive frequency so that the pan moves back and forth once every 2 seconds, and preset the total number of counter tests to 800 reciprocating cycles to ensure that the test conditions meet the standard requirements. e. Start-up testing and motion control; The reciprocating linear drive unit is activated, driving the U-shaped connecting frame to move the legs along the fixed guide rail to perform linear reciprocating motion; if the curve simulation function is enabled, the convex plate fixed to the first connecting arm contacts the roller during linear movement, and its arc or trapezoidal convex pushes the transverse slide to compress the connecting spring, causing the first connecting arm to produce transverse displacement, and then drives the pan to form a "linear + transverse" composite motion trajectory on the glass surface through the second connecting arm, thereby simulating the curved friction state of the pan bottom. f. Monitoring the testing process; Throughout the test, the movement trajectory of the pan was continuously observed to verify whether the curve amplitude met the preset value, while ensuring that the glass plate did not shift. At the same time, the operating status of the drive unit was observed and monitored to ensure the stability of the stroke, frequency and counting. If any abnormality occurred, the machine was stopped immediately for troubleshooting. g. Test termination and result determination; After 800 rounds of testing, the equipment will automatically stop. The glass plate will be removed and placed under a light source to determine whether it is qualified. If there are only slight scratches on the surface that are difficult to see with the naked eye, it is considered qualified. If there are any obvious linear scratches or flaking damage that are white, it is considered unqualified.
