Description

Technical Field

[0001] The present invention relates to the technical field of induction cooker glass-ceramics detection, and in particular to a multifunctional coating integrity detection system for induction cooker glass-ceramics. Background Art

[0002] The quality of induction cooker glass-ceramics directly impacts the user experience of induction cookers. In existing technologies, the integrity of multifunctional coatings on induction cooker glass-ceramics is typically assessed by observing the presence of visible scratches after abrasion resistance testing.

[0003] However, the human eye often cannot accurately detect relatively minor scratches. Furthermore, it is difficult to accurately assess the actual wear resistance of the multifunctional coating on induction cooker glass-ceramic by visual inspection.

[0004] In view of this, this application is hereby filed. Summary of the Invention

[0005] The purpose of the present invention is to provide an induction cooker microcrystalline glass multifunctional coating integrity detection system, which can more accurately detect the integrity of the induction cooker microcrystalline glass multifunctional coating, so that its actual wear resistance performance can be evaluated more reasonably and accurately, and at the same time, it can complete the detection at the same time as the wear resistance test, which is efficient and convenient.

[0006] The embodiment of the present invention is achieved as follows:

[0007] A multifunctional coating integrity detection system for induction cooker microcrystalline glass comprises a driving mechanism, a test bench, a bracket, a visual mechanism, a test seat and a processor.

[0008] The test bench is equipped with a projection screen. A bracket is installed on the top of the test bench to place the glass-ceramic to be tested.

[0009] The test seat is provided with a test tool, an air blowing hole and a light source. The air blowing hole is arranged toward the tip of the test tool, and the light source is arranged toward the rear of the test tool.

[0010] The test seat is installed on the driving mechanism so as to utilize the driving mechanism to control the test tool to perform a scratch test on the micro-ceramic glass to be tested.

[0011] The visual mechanism is used to obtain the projected image of the light source on the projection screen, and the processor is used to judge the integrity of the multifunctional coating of the micro-ceramic glass to be tested based on the projected image.

[0012] Furthermore, a mounting hole is provided on the bottom wall of the test seat, and the light source is installed in the mounting hole.

[0013] Matching grooves are formed on the opposite sides of the mounting hole. Along the feed direction of the test tool, the width of the matching groove is the same as the inner diameter of the mounting hole.

[0014] An adjusting wheel is rotatably fitted in each matching groove, the rotation axis of the two adjusting wheels in the two matching grooves are arranged along the feed direction of the test tool, and the wheel surfaces of the two adjusting wheels in the two matching grooves are in contact with each other.

[0015] The adjusting wheels are all provided with a notch, which extends from the wheel surface of the adjusting wheel toward the side where the rotation axis of the adjusting wheel is located, and the notch penetrates to both side walls of the adjusting wheel.

[0016] The adjusting wheels are driven by the adjusting mechanism to adjust the degree to which the adjusting wheels cover the mounting holes.

[0017] Furthermore, the two adjusting wheels in the two matching grooves are in a symmetrical relationship with respect to the central axis of the mounting hole.

[0018] Furthermore, the adjustment mechanism includes: an adjustment ring and a driver.

[0019] The test seat is further provided with an annular inner cavity, which is coaxially arranged with the mounting hole and communicates with the matching groove. The adjusting ring is rotatably matched in the annular inner cavity.

[0020] The adjusting ring has an outer gear ring and an inner thread. The wheel surface of the adjusting wheel is provided with matching teeth. The inner thread of the adjusting ring is in transmission cooperation with the matching teeth of the adjusting wheel. The outer gear ring of the adjusting ring is in transmission cooperation with the driver.

[0021] Furthermore, the test socket is further provided with an adjustment inner cavity, with adjustment inner cavities formed on opposite sides of the mating groove, the adjustment inner cavity and the mating groove being spaced apart. A communication port is formed on the side wall of the mating groove, and both mating grooves are connected to the adjustment inner cavity through the communication port.

[0022] A rotating shaft is fixedly connected to opposite sides of the adjustment wheel. The sidewalls of the rotating shaft are provided with radially extending locking holes. The rotating shaft extends into the adjustment cavity through a connecting port. Axially, the inner diameter of the connecting port matches the outer diameter of the rotating shaft. Radially, the inner diameter of the connecting port is larger than the outer diameter of the rotating shaft. A latch is fixedly connected to one end of the connecting port, closest to the central axis of the mounting hole, and the latch engages the rotating shaft.

[0023] A control arm is fixedly connected to the end of the rotating shaft remote from the adjustment wheel. The control arm is arranged radially along the rotating shaft and perpendicular to the central axis of the mounting hole. An adjustment hole is defined in the end surface of the control arm remote from the rotating shaft. An adjustment rod slidably fits within the adjustment hole. An elastic member is connected between the end of the adjustment rod and the bottom of the adjustment hole. Along the axial direction of the control arm, both the control arm and the adjustment rod slidably fit within the adjustment cavity.

[0024] The two adjusting wheels in the two matching grooves are arranged in parallel and spaced apart on the two adjusting rods on the same side. An adjusting gear is arranged between the two adjusting rods on the same side of the two adjusting wheels. A matching rack is arranged on the side of the adjusting rod close to the adjusting gear, and the adjusting rods are meshed with the adjusting gear through the matching rack.

[0025] The adjusting gear is matched with the driver transmission.

[0026] When the driver drives the adjustment ring, causing the notches of the two adjustment wheels in the two mating grooves to move toward each other, the adjustment gear, via the mating rack, drives the adjustment rod outward from the control arm. When the adjustment gear is just separated from the mating rack near the end of the control arm, the elastic member is in a stretched state. When the locking hole and the latch pin are aligned, the elastic member, through the control arm, pulls the rotating shaft toward the latch pin, allowing the latch pin to engage the locking hole. At this point, the mounting hole is at its maximum opening.

[0027] When the driver drives the adjustment ring, causing the notches of the two adjustment wheels in the two mating grooves to move toward opposite sides, the adjustment gear, via the mating rack, drives the adjustment rod toward the inside of the control arm. When the adjustment gear just separates from the mating rack at the end away from the control arm, the elastic member enters a resiliently compressed state, allowing the locking hole to disengage from the latch and allowing the adjustment wheel to re-engage with the adjustment ring.

[0028] Furthermore, the elastic member is a spring.

[0029] Furthermore, when the light beam of the light source does not exist in the projected image, the processor is used to control the test seat to stop moving and control the adjustment ring to rotate in the reverse direction.

[0030] The beneficial effects of the technical solutions of the embodiments of the present invention include:

[0031] When the induction cooker microcrystalline glass multifunctional coating integrity detection system provided by an embodiment of the present invention is tested, if the multifunctional coating on the surface of the microcrystalline glass to be tested is intact, that is, the test tool does not leave any scratches on the surface of the microcrystalline glass to be tested, then the projection of the light source in the projected image is a point that is adapted to the thickness of its light beam.

[0032] If the multifunctional coating on the surface of the glass-ceramic to be tested is no longer intact, that is, the test tool has left a scratch on the surface of the glass-ceramic to be tested, such as Figure 2 As shown, the light beams irradiated on the two side walls (slant surfaces) of the scratch will be deflected to the two sides of the scratch due to refraction, which causes the projection of the light source in the projected image to be offset in the width direction of the scratch.

[0033] This makes it possible to determine whether scratches have occurred.

[0034] In general, the induction cooker microcrystalline glass multifunctional coating integrity detection system provided by the embodiment of the present invention can more accurately detect the integrity of the induction cooker microcrystalline glass multifunctional coating, so that its actual wear resistance performance can be evaluated more reasonably and accurately. At the same time, it can complete the detection at the same time as the wear resistance test, which is efficient and convenient. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0046] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0047] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention as claimed, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort shall fall within the scope of protection of the present invention.

[0048] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0049] Furthermore, the terms "parallel" and "perpendicular" do not necessarily mean that the components must be absolutely parallel or perpendicular, but rather that they can be slightly tilted. For example, "parallel" simply means that the direction is more parallel than "perpendicular," not that the structure must be completely parallel, but rather that it can be slightly tilted.

[0050] In the description of the present invention, it should also be noted that, unless otherwise expressly specified or limited, the terms "disposed," "installed," and "connected" should be understood broadly. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediate medium, or internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0051] Please refer to Figure 1 This embodiment provides an induction cooker microcrystalline glass multifunctional coating integrity detection system, which includes: a driving mechanism (not shown in the figure), a test bench (not shown in the figure), a bracket (not shown in the figure), a visual mechanism (not shown in the figure), a test seat 100 and a processor (not shown in the figure).

[0052] The test bench is equipped with a projection screen 200. A bracket is mounted on the top of the test bench to hold the glass-ceramic 2000 to be tested. When the glass-ceramic 2000 to be tested is placed on the bracket, it is positioned above the projection screen 200, parallel to the projection screen 200, and spaced apart.

[0053] The test base 100 is provided with a test cutter 110, an air blowing hole 120 and a light source 130. The test base 100 is mounted on a driving mechanism to control the test cutter 110 to perform a scratch test on the micro-ceramic glass 2000 to be tested. The test cutter 110 is mounted on the bottom wall of the test base 100.

[0054] Taking the moving direction of the test tool 110 during the scratch test as the positive direction, the air holes 120 are located on the side of the test tool 110 away from the positive direction, that is, the air holes are located on the back side of the test tool 110 .

[0055] The air hole 120 is used to communicate with an external air supply mechanism. The air hole 120 is set toward the tip of the test tool 110 to use the air flow sent by the air supply mechanism to blow away the debris that the test tool 110 may scratch on the surface of the microcrystalline glass 2000 to be tested.

[0056] The light source 130 is located on the back side (away from the normal direction) of the air hole 120 and faces the rear of the test tool 110. This means that the light beam emitted by the light source 130 is directed toward any scratches that the test tool 110 may have made. The light path of the light source 130 is perpendicular to the test table surface. During testing, the light path of the light source 130 is perpendicular to the glass-ceramic 2000 being tested. This allows the light source 130 to illuminate any scratches left by the test tool 110 behind it through this perpendicular light path.

[0057] The visual mechanism is used to obtain the projection image of the light source 130 on the projection screen 200, and the processor is used to judge the integrity of the multifunctional coating of the micro-ceramic glass 2000 to be tested based on the projection image.

[0058] Specifically, in this embodiment, the thickness of the test tool 110 increases gradually from the tip of the test tool 110 toward the end thereof close to the test base 100. The light source 130 may be a point light source 130.

[0059] During the test, the driving mechanism is used to drive the test seat 100 to perform a scratch test on the surface of the micro-ceramic glass 2000 to be tested along a predetermined track (optionally a straight line path) and a predetermined pressure.

[0060] If the multifunctional coating on the surface of the tested glass-ceramics 2000 is intact, that is, the testing tool 110 leaves no scratches on the surface of the tested glass-ceramics 2000, then the projection of the light source 130 in the projected image is a point adapted to the thickness of its light beam.

[0061] If the multifunctional coating on the surface of the glass-ceramics 2000 to be tested is no longer intact, that is, the testing tool 110 leaves a scratch on the surface of the glass-ceramics 2000 to be tested, such as Figure 2As shown, the light beams irradiated on the two side walls (slant surfaces) of the scratch will be deflected to the two sides of the scratch due to refraction, which causes the projection of the light source 130 in the projected image to be offset in the width direction of the scratch.

[0062] This makes it possible to determine whether scratches have occurred.

[0063] In general, the induction cooker microcrystalline glass multifunctional coating integrity detection system provided in this embodiment can more accurately detect the integrity of the induction cooker microcrystalline glass multifunctional coating, so that its actual wear resistance performance can be evaluated more reasonably and accurately. At the same time, it can complete the detection at the same time as the wear resistance test, which is efficient and convenient.

[0064] In this embodiment, please combine Figure 3 and Figure 5 The bottom wall of the test seat 100 is provided with a mounting hole 140, and the light source 130 is mounted in the mounting hole 140. The mounting hole 140 is arranged perpendicular to the table surface of the test bench.

[0065] Matching grooves 150 are provided on the opposite side walls of the mounting hole 140. The width of the matching groove 150 is the same as the inner diameter of the mounting hole 140. In this embodiment, the cross-section of the cavity of the mounting hole 140 is rectangular, and the cross-section of the cavity of the matching groove 150 is also rectangular. Of the four side walls of the mounting hole 140, two are perpendicular to the direction of travel of the test tool 110, and the other two are arranged along the direction of travel of the test tool 110. The matching groove 150 is provided on the two side walls arranged along the direction of travel of the test tool 110, and the two side walls of the matching groove 150 are respectively flush with the two side walls perpendicular to the direction of travel of the test tool 110.

[0066] An adjusting wheel 160 is rotatably engaged with each mating slot 150. In this embodiment, one adjusting wheel 160 is rotatably engaged with each mating slot 150. The rotational axes of the two adjusting wheels 160 in the two mating slots 150 are both arranged along the feed direction (travel direction) of the test tool 110, and the wheel surfaces of the two adjusting wheels 160 in the two mating slots 150 are in contact with each other.

[0067] The adjusting wheel 160 defines a notch 161 . The notch 161 extends from the wheel surface of the adjusting wheel 160 toward the side where the rotation axis of the adjusting wheel 160 is located, and penetrates through both sidewalls of the adjusting wheel 160 .

[0068] The adjusting wheels 160 are driven by the adjusting mechanism to adjust the degree to which the adjusting wheels 160 cover the mounting holes 140 .

[0069] Specifically, the two adjusting wheels 160 in the two matching grooves 150 are symmetrical with respect to the central axis of the mounting hole 140 , and the notches 161 are also symmetrical with respect to the central axis of the mounting hole 140 .

[0070] The adjustment mechanism includes an adjustment ring 170 and a driver (not shown in the figure).

[0071] The test socket 100 further defines an annular inner cavity coaxially disposed with the mounting hole 140. The annular inner cavity is disposed around the mounting hole 140 and communicates with the mating groove 150. An adjustment ring 170 is rotatably engaged with the annular inner cavity and coaxially disposed with the annular inner cavity.

[0072] The adjusting ring 170 has an outer gear ring and an inner thread. The wheel surface of the adjusting wheel 160 is provided with matching teeth. The inner thread of the adjusting ring 170 is in driving cooperation with the matching teeth of the adjusting wheel 160 , and the outer gear ring of the adjusting ring 170 is in driving cooperation with the driver.

[0073] After the driver drives the adjusting ring 170 , the adjusting ring 170 can synchronously drive the two adjusting wheels 160 , so that the two adjusting wheels 160 can rotate synchronously in opposite directions.

[0074] When the notches 161 of the two adjusting wheels 160 are completely moved to the opposite side, Figure 3 As shown, at this time, the adjustment wheel 160 is completely located in the matching groove 150, and will not block the light in the mounting hole 140. The actual emitted light has the largest irradiation range in the width direction of the scratch.

[0075] When the notches 161 of the two adjusting wheels 160 are completely moved to opposite sides, Figure 4 As shown, at this time, the adjusting wheel 160 partially extends from the matching groove 150, and the wheel surfaces of the two adjusting wheels 160 are in contact with each other, which completely blocks the light in the mounting hole 140. It is in the fully closed state.

[0076] When the two adjustment wheels 160 are located between the above two states, the closer they are to the fully open state, the larger the irradiation range of the actual emitted light in the width direction of the scratch, and the closer they are to the fully closed state, the smaller the irradiation range of the actual emitted light in the width direction of the scratch.

[0077] In this embodiment, the planes corresponding to the central axis of the mounting hole 140 and the central axis of the test tool 110 are arranged along the moving direction of the test tool 110 .

[0078] In this way, by adjusting the irradiation range of the actual emitted light in the width direction of the scratch so that the irradiation range of the actual emitted light in the width direction of the scratch is just consistent with the actual width of the scratch, it is possible to effectively reduce unnecessary light interference and improve detection accuracy.

[0079] Optionally, the beam diameter of the light source 130 can be flexibly selected as needed. During the test process, the test tool 110 can be paused every time it travels a distance equal to the beam diameter, and the adjustment wheel 160 can be controlled to switch between the fully open state and the fully closed state once, and all projected images in this process are collected to facilitate a more accurate judgment on whether there are scratches.

[0080] Further, please combine Figure 5-Figure 8 The test socket 100 is further provided with an adjustment cavity 180 , and the adjustment cavities 180 are provided on opposite sides of the matching groove 150 . The two adjustment cavities 180 are respectively located on the side of the mounting hole 140 close to the positive direction and the side away from the positive direction.

[0081] The regulating inner cavity 180 is spaced apart from the matching groove 150 . A communication port 181 is formed on the sidewall of the matching groove 150 and communicates with the regulating inner cavity 180 . Both matching grooves 150 communicate with the regulating inner cavity 180 through the communication port 181 .

[0082] The adjustment wheel 160 is fixedly connected to a rotating shaft 162 on opposite sides thereof. A locking hole 163 is defined along the sidewall of the rotating shaft 162 along its radial direction. The rotating shaft 162 extends into the adjustment cavity 180 through a connecting opening 181, and the locking hole 163 is located within the connecting opening 181. The locking hole 163 is located on the side of the rotating shaft 162 closest to the notch 161.

[0083] Along the axial direction of the mounting hole 140 , the inner diameter of the communication port 181 matches the outer diameter of the rotating shaft 162 . Along the radial direction of the mounting hole 140 , the inner diameter of the communication port 181 is larger than the outer diameter of the rotating shaft 162 .

[0084] One end of the communication port 181 close to the central axis of the mounting hole 140 is fixedly connected with a latch 182 for matching with the locking hole 163. When the latch 182 is not inserted into the locking hole 163, the end of the latch 182 is in contact with the shaft 162, and the shaft 162 can still rotate smoothly.

[0085] A control arm 164 is fixedly connected to the end of the rotating shaft 162 away from the adjusting wheel 160. The control arm 164 is arranged radially along the rotating shaft 162 and perpendicular to the central axis of the mounting hole 140. An adjustment hole is defined on the end surface of the control arm 164 away from the rotating shaft 162. The adjustment hole is arranged axially along the control arm 164. An adjustment rod 165 slidably fits within the adjustment hole. An elastic member 166 is connected between the end of the adjustment rod 165 and the bottom of the adjustment hole.

[0086] Along the axial direction of the control arm 164 , the control arm 164 and the adjustment rod 165 can both be slidably fitted into the adjustment inner cavity 180 .

[0087] The two adjusting wheels 160 in the two mating grooves 150 are arranged parallel and spaced apart from the two adjusting rods 165 on the same side. An adjusting gear 167 is provided between the two adjusting rods 165 on the same side of the two adjusting wheels 160. A mating rack 168 is provided on the side of the adjusting rod 165 close to the adjusting gear 167, and the adjusting rods 165 are engaged with the adjusting gear 167 through the mating rack 168.

[0088] The adjusting gear 167 is in driving cooperation with the driver.

[0089] The adjusting ring 170 and the adjusting gear 167 are both coupled with a driver, and the driver is used to synchronously drive the adjusting ring 170 and the adjusting gear 167 .

[0090] When the driver drives the adjusting ring 170 to move the notches 161 of the two adjusting wheels 160 in the two matching grooves 150 toward one side, for example, Figure 4 The status shown is Figure 3 The state movement shown, at this time, for Figure 4 As for the adjusting wheel 160 on the left, it rotates in a clockwise direction.

[0091] At this time, the adjusting gear 167 drives the adjusting rod 165 out of the control arm 164 through the matching rack 168. When the adjusting gear 167 is just separated from the end of the matching rack 168 close to the control arm 164, the elastic member 166 is in an elastically stretched state. Figure 7 As shown, in this state, the adjusting gear 167 can continue to rotate, the adjusting ring 170 can continue to drive the adjusting wheel 160, and the rotating shaft 162 continues to rotate relative to the latch 182. When the locking hole 163 is aligned with the latch 182, the elastic member 166 can pull the rotating shaft 162 toward the latch 182 through the control arm 164, thereby making the latch 182 engage with the locking hole 163. At this time, the adjusting hole is translated a distance toward the side where the central axis of the mounting hole 140 is located, but the adjusting wheel 160 is still completely located in the engaging groove 150. At this time, the adjusting wheel 160 is locked by the latch 182, as shown in FIG. Figure 8 As shown, the mounting hole 140 is in a fully open state, and the opening degree reaches the maximum.

[0092] When it is necessary to use the driver to drive the adjusting ring 170 to move the notches 161 of the two adjusting wheels 160 in the two matching grooves 150 toward opposite sides, for example, Figure 3 The status shown is Figure 4 The state movement shown, at this time, for Figure 3As for the adjusting wheel 160 on the left side, it needs to be driven to rotate counterclockwise.

[0093] At this time, the adjusting gear 167 rotates in the opposite direction, driving the adjusting rod 165 into the control arm 164 through the mating rack 168. When the adjusting gear 167 is just separated from the end of the mating rack 168 away from the control arm 164, the elastic member 166 is in an elastically compressed state, so that the locking hole 163 can be separated from the latch 182, and the adjusting wheel 160 can be re-engaged with the adjusting ring 170. At this time, continuing to rotate the adjusting gear 167 and the adjusting ring 170 in the original direction, the notches 161 of the two adjusting wheels 160 in the two mating grooves 150 can be moved toward opposite sides, that is, Figure 3 The status shown is Figure 4 The state movement shown, at this time, for Figure 3 As for the adjustment wheel 160 on the left side, it rotates counterclockwise. At the same time, the elastic member 166 remains in a compressed state, the rotating shaft 162 continues to fit the side of the communication port 181 away from the latch 182, and the latch 182 remains separated from the locking hole 163. The adjustment wheel 160 can rotate freely to adjust the opening of the mounting hole 140.

[0094] During the test, when the light beam of the light source 130 does not exist in the projected image, that is, when the mounting hole 140 is in a fully closed state, the processor is used to control the test socket 100 to stop moving and control the adjustment ring 170 to rotate in the opposite direction.

[0095] Through the above design, the rotation range of the adjusting wheel 160 can be reasonably controlled to avoid over-adjustment, thereby improving the controllability of the adjusting wheel 160.

[0096] Optionally, the elastic member 166 is a spring.

[0097] To sum up, the induction cooker microcrystalline glass multifunctional coating integrity detection system provided by the embodiment of the present invention can more accurately detect the integrity of the induction cooker microcrystalline glass multifunctional coating, so that its actual wear resistance performance can be evaluated more reasonably and accurately. At the same time, it can complete the detection at the same time as the wear resistance test, which is efficient and convenient.

[0098] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
