Description

Technical Field

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

[0002] The quality of induction cooker glass-ceramics is directly related to the user experience of induction cooker products. In the prior art, for the multifunctional coating of induction cooker glass-ceramics, after the wear resistance test, the integrity of the corresponding multifunctional coating is generally judged by observing whether there are obvious scratches.

[0003] However, the human eye often cannot accurately observe some relatively minor scratches. In addition, it is also difficult to more accurately evaluate the actual wear resistance of the multifunctional coating of induction cooker microcrystalline glass through human eye observation.

[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 the detection can be completed 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: 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.

[0007] The test bench is provided with a projection screen. The bracket is installed on the test bench, and the bracket is used to place the micro-ceramic glass to be tested.

[0008] 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.

[0009] 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 microcrystalline glass to be tested.

[0010] The visual mechanism is used to obtain a projection 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 according to the projection image.

[0011] Furthermore, a mounting hole is provided on the bottom wall of the test seat, and the light source is installed in the mounting hole.

[0012] Matching grooves are provided on the hole walls on opposite sides of the mounting hole. Along the cutting direction of the test tool, the width of the matching groove is the same as the inner diameter of the mounting hole.

[0013] An adjusting wheel is rotatably fitted in each matching groove, the rotation axis lines 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.

[0014] The adjusting wheel is provided with a notch, the notch 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 the side walls on both sides of the adjusting wheel.

[0015] The adjusting wheels are driven by the adjusting mechanism to adjust the degree of covering of the mounting holes by the adjusting wheels.

[0016] 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.

[0017] Furthermore, the adjusting mechanism includes: an adjusting ring and a driver.

[0018] The test seat is also 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.

[0019] 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 transmission-matched with the matching teeth of the adjusting wheel, and the outer gear ring of the adjusting ring is transmission-matched with the driver.

[0020] Furthermore, the test seat is also provided with an adjustment inner cavity, and the adjustment inner cavity is provided on opposite sides of the matching groove, and the adjustment inner cavity is arranged at a distance from the matching groove. A connecting port connected to the adjustment inner cavity is provided on the side wall of the matching groove, and both matching grooves are connected to the adjustment inner cavity through the connecting port.

[0021] The adjusting wheel is fixedly connected to a rotating shaft on both sides of the opposite sides, and a locking hole arranged along the radial direction of the rotating shaft is opened on the side wall of the rotating shaft, and the rotating shaft extends into the adjusting inner cavity through the connecting port. Along the axial direction of the mounting hole, the inner diameter of the connecting port is matched with the outer diameter of the rotating shaft. Along the radial direction of the mounting hole, 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 close to the central axis of the mounting hole, and the latch fits the rotating shaft.

[0022] The end of the rotating shaft away from the adjusting wheel is fixedly connected with a control arm, which is arranged along the radial direction of the rotating shaft and perpendicular to the central axis of the mounting hole. An adjusting hole is provided on the end surface of the end of the controlling arm away from the rotating shaft, and an adjusting rod is slidably fitted in the adjusting hole, and an elastic member is connected between the end of the adjusting rod and the bottom of the adjusting hole. Along the axial direction of the controlling arm, the controlling arm and the adjusting rod can both be slidably fitted in the adjusting inner cavity.

[0023] 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.

[0024] The adjusting gear is matched with the driving device.

[0025] When the driver drives the adjustment ring to make the notches of the two adjustment wheels in the two matching grooves move toward the opposite side, the adjustment gear drives the adjustment rod out of the control arm through the matching rack. When the adjustment gear is just separated from the end of the matching rack close to the control arm, the elastic member is in an elastic stretching state, so that when the locking hole is aligned with the bolt, the elastic member can pull the shaft to move toward the bolt through the control arm, thereby making the bolt match the locking hole. At this time, the opening of the installation hole is the largest.

[0026] When the driver drives the adjusting ring to make the notches of the two adjusting wheels in the two matching grooves move toward opposite sides, the adjusting gear drives the adjusting rod into the control arm through the matching rack. When the adjusting gear just separates from the end of the matching rack away from the control arm, the elastic member is in an elastically compressed state, so that the locking hole can be separated from the latch and the adjusting wheel can be re-matched with the adjusting ring.

[0027] Furthermore, the elastic member is a spring.

[0028] 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 opposite direction.

[0029] The beneficial effects of the technical solution of the embodiment of the present invention include: When the induction cooker microcrystalline glass multifunctional coating integrity detection system provided by the 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 matches the thickness of its light beam.

[0030] If the multifunctional coating on the surface of the tested glass-ceramic is no longer intact, that is, the test tool leaves a scratch on the surface of the tested glass-ceramic, such as Figure 2 As shown, the light beams irradiated on the two side walls (inclined 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.

[0031] This makes it possible to determine whether scratches have occurred.

[0032] 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, and the detection can be completed at the same time as the wear resistance test, which is efficient and convenient.

DETAILED DESCRIPTION

[0036] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are 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 here can be arranged and designed in various different configurations.

[0037] 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 claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] 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, further definition and explanation thereof is not required in subsequent drawings.

[0039] In addition, the terms "parallel", "vertical", etc. do not mean that the components must be absolutely parallel or vertical, but can be slightly tilted. For example, "parallel" only means that its direction is more parallel than "vertical", and does not mean that the structure must be completely parallel, but can be slightly tilted.

[0040] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "setting", "installation" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be a communication between the two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0041] Please refer to Figure 1 The present 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).

[0042] The table top of the test bench is provided with a projection screen 200. A bracket is installed on the test bench, and the bracket is used to place the micro-ceramic glass 2000 to be tested. When the micro-ceramic glass 2000 to be tested is placed on the bracket, the micro-ceramic glass 2000 to be tested is located above the projection screen 200 and is parallel to the projection screen 200 and spaced apart.

[0043] The test base 100 is provided with a test cutter 110, a blowing hole 120 and a light source 130. The test base 100 is installed on a driving mechanism to control the test cutter 110 to perform a scratch test on the microcrystalline glass 2000 to be tested. The test cutter 110 is installed on the bottom wall of the test base 100.

[0044] Taking the moving direction of the test tool 110 during the scratch test as the positive direction, the air hole 120 is located on the side of the test tool 110 away from the positive direction, that is, the air outlet is located on the back side of the test tool 110 .

[0045] 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 airflow 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.

[0046] The light source 130 is located on the back side (the side away from the positive direction) of the blowing hole 120, and the light source 130 is arranged toward the rear of the test tool 110, that is, the light beam emitted by the light source 130 is directed toward the scratches that may be made by the test tool 110. The light path of the light source 130 is arranged perpendicular to the table of the test table, that is, during the test, the light path of the light source 130 is perpendicular to the micro-ceramic glass 2000 to be tested. In this way, the light source 130 can illuminate the scratches left behind by the test tool 110 through the vertical light path.

[0047] 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 determine the integrity of the multifunctional coating of the micro-ceramic glass 2000 to be tested according to the projection image.

[0048] Specifically, in this embodiment, the thickness of the test cutter 110 increases gradually from the tip of the test cutter 110 to the end thereof close to the test seat 100. The light source 130 may be a point light source 130.

[0049] 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.

[0050] 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 that matches the thickness of its light beam.

[0051] If the multifunctional coating on the surface of the tested glass-ceramics 2000 is no longer intact, that is, the testing tool 110 leaves scratches on the surface of the tested glass-ceramics 2000, such as Figure 2As shown, the light beams irradiated on the two side walls (inclined 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.

[0052] This makes it possible to determine whether scratches have occurred.

[0053] 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.

[0054] 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 table.

[0055] Matching grooves 150 are provided on the hole walls on opposite sides 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 the present embodiment, the cross-section of the hole cavity of the mounting hole 140 is rectangular, and the cross-section of the groove cavity of the matching groove 150 is also rectangular. Among the four side walls of the mounting hole 140, two are perpendicular to the moving direction of the test tool 110, and the other two are arranged along the moving direction of the test tool 110. The matching groove 150 is provided on the two side walls arranged along the moving direction 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 moving direction of the test tool 110.

[0056] An adjusting wheel 160 is rotatably engaged in each matching groove 150. In this embodiment, an adjusting wheel 160 is rotatably engaged in each matching groove 150. The rotation axis of the two adjusting wheels 160 in the two matching grooves 150 are 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 matching grooves 150 are in contact with each other.

[0057] The adjusting wheel 160 is provided with 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 the notch 161 penetrates through the two side walls of the adjusting wheel 160 .

[0058] 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 .

[0059] 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 notch 161 is also symmetrical with respect to the central axis of the mounting hole 140 .

[0060] The adjustment mechanism includes: an adjustment ring 170 and a driver (not shown in the figure).

[0061] The test seat 100 also has an annular inner cavity, which is coaxially arranged with the mounting hole 140, annularly arranged around the mounting hole 140, and communicates with the matching groove 150. The adjustment ring 170 is rotatably fitted in the annular inner cavity, and the adjustment ring 170 is coaxially arranged with the annular inner cavity.

[0062] 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. The outer gear ring of the adjusting ring 170 is in driving cooperation with the driver.

[0063] 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.

[0064] 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, and the actual emitted light has the largest irradiation range in the width direction of the scratch.

[0065] When the notches 161 of the two adjusting wheels 160 are completely moved to the opposite side, Figure 4 As shown, at this time, the adjusting wheel 160 partially extends out from the matching groove 150, and the wheel surfaces of the two adjusting wheels 160 are in contact with each other, which will completely block the light in the mounting hole 140. It is in the fully closed state.

[0066] When the two adjustment wheels 160 are located between the above two states, the closer 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 to the fully closed state, the smaller the irradiation range of the actual emitted light in the width direction of the scratch.

[0067] 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 .

[0068] 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 excess light interference and improve detection accuracy.

[0069] Optionally, the beam diameter of the light source 130 can be flexibly selected as needed. During the test, the test tool 110 can be paused after traveling 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 can be collected to facilitate a more accurate judgment on whether there are scratches.

[0070] Further, please combine Figure 5-Figure 8 The test socket 100 is further provided with an adjustment inner cavity 180 , and the adjustment inner cavities 180 are provided on opposite sides of the matching groove 150 , and the two adjustment inner 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.

[0071] The adjusting inner cavity 180 is spaced apart from the matching groove 150 . A communication port 181 communicating with the adjusting inner cavity 180 is formed on the side wall of the matching groove 150 . Both matching grooves 150 communicate with the adjusting inner cavity 180 through the communication port 181 .

[0072] The two opposite sides of the adjusting wheel 160 are fixedly connected with a rotating shaft 162, and the side wall of the rotating shaft 162 is provided with a locking hole 163 arranged along its radial direction. The rotating shaft 162 extends into the adjusting inner cavity 180 through the connecting port 181, and the locking hole 163 is located in the connecting port 181. The locking hole 163 is provided on one side of the rotating shaft 162 close to the notch 161.

[0073] 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 greater than the outer diameter of the rotating shaft 162 .

[0074] One end of the communication port 181 close to the central axis of the mounting hole 140 is fixedly connected with a latch 182 adapted to the locking hole 163. When the latch 182 is not inserted into the locking hole 163, the end of the latch 182 fits the shaft 162, and the shaft 162 can still rotate smoothly.

[0075] A control arm 164 is fixedly connected to one end of the rotating shaft 162 away from the adjusting wheel 160. The control arm 164 is arranged along the radial direction of the rotating shaft 162 and perpendicular to the central axis of the mounting hole 140. An adjusting hole is provided on the end surface of the end of the control arm 164 away from the rotating shaft 162. The adjusting hole is arranged along the axial direction of the control arm 164. An adjusting rod 165 is slidably fitted in the adjusting hole. An elastic member 166 is connected between the end of the adjusting rod 165 and the bottom of the adjusting hole.

[0076] 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 .

[0077] The two adjusting wheels 160 in the two matching grooves 150 are arranged in parallel and spaced apart from the two adjusting rods 165 on the same side. An adjusting gear 167 is arranged between the two adjusting rods 165 on the same side of the two adjusting wheels 160. A matching rack 168 is arranged on one side of the adjusting rod 165 close to the adjusting gear 167. The adjusting rods 165 are meshed with the adjusting gear 167 through the matching rack 168.

[0078] The adjusting gear 167 is in driving cooperation with the driver.

[0079] The adjusting ring 170 and the adjusting gear 167 are both in transmission cooperation with a driver, and the driver is used for synchronously driving the adjusting ring 170 and the adjusting gear 167 .

[0080] 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 the clockwise direction.

[0081] 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, such as Figure 7 As shown, in this state, the adjusting gear 167 can continue to rotate, the adjusting ring 170 can also 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 to move toward the latch 182 through the control arm 164, so that the latch 182 is matched with the locking hole 163. At this time, the adjusting hole is translated to the side where the central axis of the mounting hole 140 is located for a distance, but the adjusting wheel 160 is still completely located in the matching 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.

[0082] When the driver is required 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 in the counterclockwise direction.

[0083] At this time, the adjusting gear 167 rotates in the opposite direction, and drives the adjusting rod 165 into 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 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, the adjusting gear 167 and the adjusting ring 170 continue to rotate in the original direction, so that the notches 161 of the two adjusting wheels 160 in the two matching grooves 150 can move to the opposite side, that is: Figure 3 The status shown is Figure 4 The state movement shown, at this time, for Figure 3 As for the adjusting wheel 160 on the left, it rotates counterclockwise. Meanwhile, the elastic member 166 is continuously in a compressed state, the rotating shaft 162 is continuously attached to the side of the communication port 181 away from the latch 182, the latch 182 is kept separated from the locking hole 163, and the adjusting wheel 160 can rotate freely to adjust the opening of the mounting hole 140.

[0084] 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.

[0085] 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 .

[0086] Optionally, the elastic member 166 is a spring.

[0087] 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, and the detection can be completed at the same time as the wear resistance test, which is efficient and convenient.

[0088] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
