Description

Technical Field

[0001] The invention relates to the technical field of induction cooker panels, in particular to an induction cooker panel performance detection device. Background Art

[0002] Induction cooker panels are mainly divided into two categories: microcrystalline glass panels and ceramic panels. These two materials are suitable for different usage scenarios and personal needs and preferences. Among them, microcrystalline glass panels are the most commonly used induction cooker panel materials on the market. They have good heat resistance and impact resistance, and can withstand high temperature changes without breaking. At the same time, they also have good magnetic line penetration performance, which helps to improve the working efficiency of the induction cooker.

[0003] The performance of the microcrystalline glass panel is crucial to ensuring the product safety and durability of the induction cooker, so it is necessary to test the impact resistance, thermal shock resistance, and wear resistance of the microcrystalline glass panel. Currently, when testing the impact resistance of the microcrystalline glass panel, a punch is set above the panel and released at a certain height. The punch impacts the panel under the action of gravity, thereby simulating the situation of external impact during use, thereby testing the impact resistance of the panel.

[0004] The above-mentioned impact resistance test process has the following problems: only a single test scenario is set, and different temperatures, different impact heights (impact height is equivalent to impact strength) and different impact angles cannot be simulated. In the actual use scenario, the panel is in a complex situation. The result obtained by testing the panel under the premise of simulating the actual situation is true and reliable. For the current testing method, in order to simulate different situations, the panel needs to be adjusted many times. The operation process is cumbersome and the testing efficiency is not ideal. Secondly, the panel impact resistance test is mainly judged by the damage of the panel.

DETAILED DESCRIPTION

[0032] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0033] like Figure 1 and Figure 2 As shown, an induction cooker panel performance detection device comprises: two fixing frames 1 arranged symmetrically front to back, the two fixing frames 1 respectively corresponding to a high temperature group and a normal temperature group from front to back, a plurality of supporting frames 2 equidistantly arranged from left to right are fixedly provided on the lower end surface of the fixing frame 1, a locking column 3 with an axis extending from left to right is movably mounted on the lower end surfaces of all the supporting frames 2 on the same fixing frame 1, the locking column 3 can move along its axis and also rotate, and the locking column 3 is driven by an external hydraulic cylinder (not shown in the figure) to move left and right.

[0034] like Figure 1 , Figure 2 and Figure 4As shown, the left end surface of the support frame 2 is hingedly provided with a base plate 4 through a hinge frame, the locking column 3 slides left and right and penetrates the base plate 4, and a clamping mechanism 5 for clamping the panel to be tested is arranged on the base plate 4, and the clamping mechanism 5 includes a rectangular plate 50, and a rectangular plate 50 is arranged above the base plate 4, and a supporting plate 500 is fixedly provided on the upper end surface of the rectangular plate 50 through two front and rear distributed connecting columns, and four circumferentially distributed V-shaped plates 501 are arranged on the supporting plate 500, and a driving unit 52 for driving the V-shaped plate 501 to clamp the panel is commonly arranged on the base plate 4, the rectangular plate 50 and the supporting plate 500.

[0035] like Figure 1 and Figure 2 As shown, the rectangular plate 50 and the adjacent support frame 2 are jointly provided with an adjustment unit 6 for adjusting the height and tilt angle of the support plate 500. The adjustment unit 6 realizes the adjustment function through the movement and rotation process of the locking column 3. A test rod 7 is installed on the fixed frame 1, which slides up and down and corresponds to the support plate 500 one by one. A test piece 70 is provided on the lower end surface of the test rod 7. The lower end surface of the test piece 70 has the same shape as the bottom of a pot used in daily life. A driving group 8 for driving the test piece 70 to hit the panel is jointly provided on the two fixed frames 1.

[0036] like Figure 3 and Figure 5 As shown, a receiving groove is provided on the upper end surface of all the supporting plates 500 on the front side, and an electric heating plate 9 is fixedly installed in the receiving groove.

[0037] The adjustment unit 6 adjusts the multiple panels after being clamped to different heights or different angles, so that the multiple panels together form a test group with different heights and different inclination angles at normal temperature and a control group with the same height and inclination angle at high temperature and normal temperature, so as to simultaneously perform impact resistance test operations on the panels under different situations.

[0038] During operation, the heights of all the supporting plates 500 on the same fixing frame 1 are adjusted through the adjustment unit 6 according to the required test conditions, that is, the straight-line distance between the supporting plate 500 and the corresponding fixing frame 1 is adjusted, the test piece 70 is assembled, and the impact area of ​​the lower end of the test piece 70 at the same height is different, so that two comparison groups with different heights but the same impact area of ​​the test piece 70 and the same height but different impact area of ​​the test piece 70 are formed on the two fixing frames 1. At the same time, the electric heating plate 9 is energized for heating, thereby forming multiple comparison groups with the same height and the same impact area of ​​the test piece 70 but different temperatures. After that, the panel to be tested is manually placed on the corresponding supporting plate 500, and the panel is clamped by the V-shaped plate 501 in the clamping mechanism 5. The driving group 8 works to release the test piece 70 from the specified height. Through the gravity of the test piece 70 itself, the test piece 70 falls freely and hits the corresponding panel, thereby testing the impact resistance of the panel under different conditions at one time.

[0039] Secondly, the angle of the support plate 500 is adjusted through the adjustment unit 6, and the support plate 500 is locked, so as to change the angle between the panel and the test piece 70, that is, change the angle at which the test piece 70 hits the panel, and repeat the above test to simulate the impact situation during daily use, thereby improving the comprehensiveness of performance testing and ensuring that the test results are reliable and true.

[0040] See also Figure 2 The figure shows multiple control groups at the same operating temperature, wherein control groups with different impact intensities are formed by setting different heights, and control groups with different impact areas are formed by setting test pieces 70 of different sizes. In conjunction with the high temperature state on another fixed frame 1, control groups with different operating temperatures are formed, and multiple detection processes of different single change factors are carried out simultaneously. It should be noted that by increasing the number of control groups, multiple control detection processes can be achieved.

[0041] like Figure 1 , Figure 3 and Figure 5 As shown, the clamping mechanism 5 also includes a sliding block 51, and four circumferentially distributed sliding blocks 51 are slidably and penetrated on the supporting plate 500. The V-shaped plate 501 is fixedly arranged on the upper end surface of the corresponding sliding block 51, and a lower pressure strip 510 is fixedly arranged on the upper end surface of the V-shaped plate 501. The end of the lower pressure strip 510 close to the center position of the supporting plate 500 is chamfered.

[0042] like Figure 1 , Figure 2 and Figure 5 As shown, the driving unit 52 includes a circular rod 520, and the rectangular plate 50 is penetrated by a circular rod 520 that slides up and down. A circular plate 521 located between the supporting plate 500 and the rectangular plate 50 is fixedly sleeved on the circular rod 520. A hinge bar 1 522 is hingedly provided between the upper end surface of the circular plate 521 and the corresponding sliding blocks 51 on the left and right sides. Another hinge bar 2 523 is hingedly provided on the lower end surfaces of the other two sliding blocks 51 and the circular plate 521 in a one-to-one manner. The corresponding two hinge bars 2 523 are slidably connected by a connecting column, and a spring 1 524 sleeved on the connecting column is fixedly provided between the corresponding two hinge bars 2 523, and a spring 2 525 sleeved on the circular rod 520 is fixedly provided between the circular plate 521 and the rectangular plate 50.

[0043] like Figure 1 and Figure 5As shown, the driving unit 52 also includes a rectangular block 526, and a rectangular block 526 corresponding to the base plate 4 is slidably sleeved on the locking column 3, and the rectangular block 526 is located on the left side of the corresponding base plate 4, and a pulling bar 527 is hingedly arranged between the rectangular block 526 and the corresponding circular rod 520, and a mounting circular plate 528 corresponding to the rectangular block 526 is fixedly sleeved on the locking column 3, and the mounting circular plate 528 is located on the right side of the corresponding rectangular block 526, and a spring three 529 sleeved on the locking column 3 is fixedly arranged between the mounting circular plate 528 and the rectangular block 526.

[0044] During operation, after the panel to be tested is manually placed on the supporting plate 500, the external hydraulic cylinder works to move the locking column 3 to the left. During the movement of the locking column 3 to the left, all the mounting circular plates 528 are driven to move synchronously. The mounting circular plates 528 push the corresponding spring three 529 to move synchronously. The pulling bar 527 pulls the circular rod 520 downward through the spring three 529. The circular rod 520 pulls the circular plate 521 downward, so that the spring two 525 is compressed. The circular plate 521 pulls the hinged bar one 522 and the hinged bar two 523 thereon to move downward synchronously. The sliding block 51 corresponding to the hinged bar two 523 on the same circular plate 521 is first The V-shaped plate 501 on it is driven to stick to the panel, and as the circular plate 521 continues to move downward, the spring 524 is stretched, and the elastic force generated by the stretching of the spring 524 makes the V-shaped plate 501 corresponding to the hinge bar 523 press the panel, and the circular plate 521 drives the corresponding V-shaped plate 501 to press the panel through the hinge bar 522, so the four V-shaped plates 501 on the same support plate 500 cooperate with each other to clamp the panel. It should be noted that the corresponding V-shaped plate 501 clamps the panel by stretching the spring 524, so that the above clamping method can adapt to the clamping requirements of rectangles of different sizes.

[0045] During the movement of the V-shaped plate 501, the lower pressure strip 510 thereon moves synchronously, and finally the corresponding four lower pressure strips 510 press the corresponding panel tightly and limit it on the corresponding supporting plate 500, thereby ensuring the stability of the panel during subsequent testing. At the same time, the shape of the V-shaped plate 501 can adapt to the clamping requirements of panels of different shapes such as rectangle and circle.

[0046] After the locking column 3 is reset to the right, the circular plate 521 and the rectangular block 526 are reset respectively due to the elastic force generated by the compression of the second spring 525 and the compression deformation of the third spring 529.

[0047] like Figure 1 , Figure 4 , Figure 5 and Figure 6As shown, the adjustment unit 6 also includes an adjustment bar 60, and the upper end surface of the base plate 4 is hingedly provided with two adjustment bars 60 distributed front and back, and a through slot 600 corresponding to the adjustment bar 60 is opened on the rectangular plate 50, and the adjustment bar 60 passes through the through slot 600, and a plurality of adjustment slots 601 equidistantly arranged up and down are opened from left to right on the adjustment bar 60, and a square block 602 that slides up and down is provided on the support frame 2, and a moving bar 603 is provided between the square block 602 and the corresponding rectangular plate 50 through a moving rod for joint movement, and an adjustment column 604 corresponding to the adjacent adjustment slot 601 is fixedly provided on the left end surface of the moving bar 603.

[0048] like Figure 6 As shown, a guide groove 61 is formed on the right end surface of the adjustment bar 60 .

[0049] like Figure 1 , Figure 4 and Figure 5 As shown, the adjusting unit 6 also includes a rectangular slot 62, a rectangular slot 62 is opened on the adjusting bar 60 from left to right, a T-shaped plate 620 is rotatably sleeved on the locking column 3, a sliding column 621 which penetrates the adjacent support frames 2 from left to right is fixedly provided on the right end surface of the T-shaped plate 620, a column group corresponding to two adjacent rectangular slots 62 is fixedly provided on the left end surface of the horizontal section of the T-shaped plate 620, the column group includes a plurality of latch columns 622 arranged equidistantly from front to back, a pushing bar 623 is sleeved on the sliding column 621 and the adjacent moving rod, the pushing bar 623 is fixedly connected to the sliding column 621 and movably connected to the moving rod, the pushing bar 623 can move and rotate along the corresponding moving rod, the upper and lower pushing bars 623 are slidably connected up and down by a connecting column, a spring four 624 is commonly provided between the pushing bar 623 on the moving rod and the moving bar 603, and the spring four 624 is rotatably connected to the pushing bar 623.

[0050] It should be noted that an external electric push rod (not shown in the figure) is provided on the base plate 4 for lifting the rectangular plate 50 and moving it upward, and the telescopic end of the external electric push rod is in contact with the corresponding rectangular plate 50, that is, when the telescopic end of the external electric push rod is extended, the telescopic end lifts the rectangular plate 50, and when the telescopic end is retracted, the rectangular plate 50 moves downward under the action of its own gravity and the gravity of the structure above it, thereby realizing the process of adjusting the upper and lower heights of the rectangular plate 50.

[0051] In the initial state, the adjusting column 604 is located in the guide groove 61 but does not cooperate with the adjusting groove 601, so the rectangular plate 50 can be moved up and down for adjustment at this time, and then the external electric push rod works to drive the rectangular plate 50 and the corresponding supporting plate 500 to move up and down, and the distance between the supporting plate 500 and the fixing frame 1 is adjusted according to the required impact distance, so as to adapt to different test requirements. At this time, the adjusting column 604 is made to be opposite to the adjusting groove 601 at the corresponding position, and then the panel is placed on the supporting plate 500 for the clamping and locking process of the panel. In this process, the locking column 3 moves leftward, and the locking column 3 first drives the locking column 3 to move leftward during the process of moving leftward. The two upper and lower opposing push bars 623 move left synchronously, and the upper push bar 623 pushes the spring four 624 to move synchronously. The elastic force generated by the deformation of the spring four 624 pushes the moving bar 603 to move left, and the moving bar 603 drives the adjustment column 604 thereon to insert into the corresponding adjustment groove 601, thereby completing the locking of the upper and lower heights of the rectangular plate 50. Secondly, as the locking column 3 continues to move left, the locking column 3 drives the T-shaped plate 620 and the latch column 622 thereon to insert into the rectangular groove 62, thereby fixing the angles of the two adjustment bars 60 on the same base plate 4. During this process, the spring four 624 is continuously compressed, and then a performance test operation is performed.

[0052] When it is necessary to change the angle of impact of the panel, when the above-mentioned latch column 622 is not inserted into the rectangular groove 62 but the adjustment column 604 is inserted into the adjustment groove 601, the locking column 3 is rotated, and the locking column 3 drives the bottom plate 4 to rotate a specified angle, and the bottom plate 4 drives the rectangular plate 50 and the supporting plate 500 to rotate through the two adjustment bars 60 thereon. At this time, the supporting plate 500 and the rectangular plate 50 rotate around the axis of the moving rod at a specified angle. During this process, the corresponding two adjustment bars 60 remain in a vertical direction, and the rectangular groove 62 is opposite to the corresponding latch column 622. Then, the locking column 3 continues to move to the left, and the latch column 622 is inserted into the corresponding rectangular groove 62. In summary, the rectangular plate 50 is locked while the angle adjustment is completed, and then performance tests under different impact angles can be carried out.

[0053] In the above process, the guide groove 61 is set to limit the control adjustment bar 60 and the corresponding adjustment column 604 are always in a ready-to-match state, so that in the subsequent process of the adjustment column 604 limiting the height of the rectangular plate 50, it is ensured that the adjustment column 604 can be accurately inserted into the adjustment groove 601.

[0054] like Figure 1 , Figure 2 and Figure 7 As shown, a fixing block 71 is fixedly provided on the lower end surface of the test rod 7, a mounting block 710 is slidably installed on the lower end surface of the fixing block 71, the test piece 70 is fixedly provided on the lower end surface of the mounting block 710, a locking groove is provided on the mounting block 710, and a locking pin 711 is slidably provided on the fixing block 71.

[0055] like Figure 7The left and right end surfaces of the fixing block 71 are both fixedly provided with mounting rods 72 with axes extending from left to right, and a weight-increasing ring 720 is sleeved on the mounting rods 72 .

[0056] Before performing the performance test, the test pieces 70 with different bottom areas are manually clamped on the fixed block 71 through the mounting block 710 thereon, and the locking pin 711 is inserted to complete the locking of the test piece 70, so as to adapt to the test requirements under different impact area conditions. By arranging different numbers of weight rings 720 on the mounting rod 72, the size of the force applied when the test piece 70 hits the panel can be adjusted, and the height adjustment process can be used to realize the adjustment process of multiple forces to meet the diverse needs of the test.

[0057] like Figure 1 , Figure 2 and Figure 7 The driving group 8 includes a connecting bar 80, and the upper end surface of the test rod 7 is fixedly provided with a connecting bar 80. A hydraulic cylinder with a vertical axis is fixedly provided between the two fixing frames 1 through a base. The hydraulic cylinder corresponds to the two connecting bars 80 opposite to each other in front and back. A bidirectional electric push rod 800 is fixedly provided at the telescopic end of the hydraulic cylinder through a mounting seat, and both telescopic ends of the bidirectional electric push rod 800 are fixedly provided with a supporting bar 801.

[0058] During the test, the two supporting bars 801 on the bidirectional electric push rod 800 are located below the connecting bar 80, and the hydraulic cylinder works to drive the two supporting bars 801 to rise. When the supporting bars 801 push the connecting bar 80 and the corresponding test piece 70 to the specified height, the bidirectional electric push rod 800 works to make the two supporting bars 801 approach each other, and the connecting bar 80 loses the supporting effect of the supporting bar 801 and falls freely, causing the test piece 70 to hit the panel for performance testing.
