Description

Technical Field

[0001] This utility model relates to a zinc oxide varistor ceramic processing system, and in particular to an automatic peeling device for square zinc oxide varistor ceramics after sintering. Background Technology

[0002] Zinc oxide varistors are generally in the form of square or round sheets, with square sheets being the most common. During sintering, hundreds or thousands of square zinc oxide varistors are typically coated with anti-sticking powder, stacked in a special sagger, and then placed in a high-temperature furnace for sintering. After high-temperature sintering, the ceramic sheets adhere tightly to each other, making them difficult to separate.

[0003] Currently, the method for peeling ceramic sheets after sintering is rather rudimentary. Generally, a worker holds a utility knife blade in one hand and a tapping device in the other, placing the blade at the seam between adjacent ceramic sheets. Because the edges of ceramic sheets usually have chamfers, there is typically a V-shaped groove at the seam. The blade of the utility knife can easily enter the bottom of this groove, and the adhered ceramic sheet can be peeled off by gently tapping the back of the blade. The main drawbacks of this method are that it is time-consuming and labor-intensive, has low peeling efficiency, is uncontrollable, and carries the risk of damaging the ceramic sheet.

[0004] As zinc oxide varistors have been widely used in the industrial field, market demand has surged, and the application scenarios have increasingly higher requirements for the product quality of zinc oxide varistors. Therefore, it is necessary to upgrade the peeling process from the perspective of improving production efficiency and ensuring product quality in order to meet market demand.

[0005] To address this, we developed a dedicated automatic peeling device for square zinc oxide pressure-sensitive ceramics after sintering, in order to overcome the aforementioned shortcomings. Utility Model Content

[0006] To address the aforementioned technical problems, this invention provides an automatic peeling device for square zinc oxide pressure-sensitive ceramics after sintering. The system of this invention features high automation, time and labor savings, high peeling efficiency, precise and controllable operation, low risk of residual wafers, reliable product quality, and a reasonable design.

[0007] The technical solution of this utility model:

[0008] An automatic peeling device for square zinc oxide pressure-sensitive ceramic after sintering includes an operating table with a peeling groove on the operating table. One end of the peeling groove is provided with a feeding port, an automatic peeling machine is provided above the feeding port, and an automatic pushing mechanism is provided on one side of the peeling groove.

[0009] The automatic peeling machine includes a housing standing on the operating table, one side of which is suspended above the peeling groove, and a peeling assembly and a position sensing assembly are connected inside.

[0010] The peeling assembly includes a peeling blade extending downward to the bottom of the housing, and the peeling blade is connected to a reciprocating drive device;

[0011] The position sensing component includes a linkage plate extending downward to the bottom of the housing, the horizontal plane of the lower end of the linkage plate being lower than the horizontal plane of the lower end of the peeling blade; the linkage plate and the peeling blade are located on the same vertical plane, and this vertical plane is parallel to the gap surface of the zinc oxide pressure-sensitive ceramic during peeling.

[0012] The upper end of the linkage plate is connected to the guide column, and a micro switch is provided at the connection point; the micro switch, the automatic feeding mechanism and the reciprocating drive device are connected to the controller.

[0013] This solution uses a peeling groove to limit the stacked ceramic sheets, feeds them through an automatic feeding mechanism, and peels them off using an automatic peeling machine. This achieves automated peeling, saving manpower, improving processing efficiency, and offering higher controllability, reducing the risk of accidental damage, and ensuring product quality. Furthermore, by rationally designing the structure and positional relationship between the position sensing component and the peeling component, this solution further improves the position judgment capability, making the peeling position more accurate, reducing the probability of misjudgment, avoiding accidental damage, and further ensuring product quality.

[0014] Preferably, in the aforementioned automatic peeling device for sintered square zinc oxide pressure-sensitive ceramic, the peeling blade is connected to the reciprocating drive device via a guide post two and a connecting rod that are interconnected, wherein the guide post two is slidably connected in the guide sleeve two inside the housing.

[0015] In this solution, by setting guide post two and guide sleeve two, the position of the peeling knife is more fixed, avoiding displacement of the peeling knife due to long-term processing, thereby further ensuring processing reliability.

[0016] Preferably, in the aforementioned automatic peeling device for sintered square zinc oxide pressure-sensitive ceramic, the lower end of the second guide post is provided with an upwardly recessed square inner hole, the width of which is greater than the thickness of the peeling blade. The upper end of the peeling blade is connected to the side of the square inner hole away from the feed port via a rotating shaft, and a spring is provided between the other side and the peeling blade.

[0017] This solution avoids damage to the equipment caused by the large thickness of the peeling blade by making the peeling blade a flip-up structure. In addition, the flip-up peeling blade can also provide an outward pushing force to help separate the peeled ceramic pieces, making the design more reasonable.

[0018] Preferably, in the aforementioned automatic peeling device for sintered square zinc oxide pressure-sensitive ceramic, the lower end of the linkage plate is slidably connected to a strip roller, and the axial direction of the strip roller is parallel to the gap surface of the zinc oxide pressure-sensitive ceramic during peeling.

[0019] This solution, by installing strip rollers below the linkage plate, allows the linkage plate to make sliding contact with the surface of the ceramic sheet, further avoiding accidental damage to the ceramic sheet and ensuring product quality.

[0020] Preferably, in the aforementioned automatic peeling device for sintered square zinc oxide pressure-sensitive ceramic, the lower end of the guide column has an upward-facing T-shaped inner hole in the middle, and the upper end of the linkage plate has a T-shaped structure that mates with the T-shaped inner hole; a second spring is provided between the top of the linkage plate and the top of the T-shaped inner hole, and contacts A and B are respectively provided on the lower side of the top edge of the linkage plate and the lower side of the top edge of the T-shaped inner hole. The second spring, contacts A and B constitute the micro switch, and contacts A and B are respectively connected to the controller.

[0021] The micro switch in this solution is implemented through micro contacts A and B and spring 2. It has a simple structure, reasonable design, and strong practicality.

[0022] Preferably, in the aforementioned automatic peeling device for sintered square zinc oxide pressure-sensitive ceramic, the guide post one is slidably connected to the guide sleeve one inside the housing. The top of the guide post one is provided with a vertically downward internal threaded hole, and an adjusting screw is threadedly connected inside. The top of the adjusting screw is provided with a bevel gear one, and a bevel gear two meshes with one side of the bevel gear one. The central shaft of the bevel gear two extends out of the housing and is connected to an adjusting handle.

[0023] This solution achieves height adjustment of the linkage plate by sliding the guide post one into the guide sleeve one and adjusting the longitudinal height of the guide post one by adjusting the screw, so as to meet the peeling of ceramic pieces of different heights and sizes, making it more practical.

[0024] Preferably, in the aforementioned automatic peeling device for sintered square zinc oxide pressure-sensitive ceramic, the housing is provided with a micro switch working indicator light, which is connected to the controller.

[0025] This solution uses a microswitch indicator light to visually determine the adjustment height of the linkage plate, making operation more convenient and practical.

[0026] Preferably, in the aforementioned automatic peeling device for sintered square zinc oxide pressure-sensitive ceramic, the automatic feeding mechanism includes a chute located on one side of the peeling groove and parallel to it. A feeding screw parallel to the peeling groove is provided in the chute, and a slider is threadedly connected to the feeding screw. The slider is in close contact with the inner wall of the chute, and a crank arm is provided on the side of the slider near the peeling groove, with the end of the crank arm extending into the peeling groove. One end of the feeding screw is connected to a feeding motor, and the feeding motor is connected to the controller.

[0027] This solution utilizes a combination of a pusher screw, slider, chute, and pusher motor to push ceramic sheets. The pushing process is continuous and smooth, with a simpler structure and a more reasonable design.

[0028] Preferably, in the aforementioned automatic peeling device for sintered square zinc oxide pressure-sensitive ceramic, a V-shaped limiting groove is provided on the side of the crank arm near the automatic peeling machine. A limiting plate is provided on each side of the peeling groove near the feeding port. Multiple springs are provided between the back of the limiting plate and the side wall of the peeling groove. The line connecting the midpoint of the vertical line between two limiting plates and the intersection of the V-shaped limiting groove is parallel to the length direction of the peeling groove.

[0029] This solution incorporates a V-shaped limiting groove on one side of the crank arm and a limiting piece that presses from both sides towards the center at the material feeding end of the peeling groove. This ensures that the stacking direction of the ceramic sheets is always parallel to the centerline of the peeling groove, thus keeping the peeling gap surface parallel to the peeling blade and the linkage plate. This prevents the gap surface from forming an angle with the surface where the peeling blade is located, which could damage the ceramic sheets. This solution further ensures the reliability of processing and reduces the risk of accidental damage. Furthermore, it can process ceramic sheets of different widths, making it more practical.

[0030] Preferably, in the aforementioned automatic peeling device for sintered square zinc oxide pressure-sensitive ceramic, the inlet end of the limiting plate is provided with an outwardly flipped arc-shaped surface.

[0031] This solution features an outward-flipping arc-shaped surface at the entrance end of the limiting plate, making it easier for the ceramic plate to enter between the limiting plates, resulting in more convenient operation and a more reasonable design.

[0032] The beneficial effects of this utility model are:

[0033] 1. This utility model limits the stacked ceramic sheets by using a peeling groove, feeds them through an automatic feeding mechanism, and peels them off using an automatic peeling machine. This achieves automated peeling, saves manpower, improves processing efficiency, and offers higher controllability, lower risk of accidental damage, and better product quality assurance. Furthermore, by rationally designing the structure and positional relationship between the position sensing component and the peeling component, this utility model further improves the position judgment capability, making the peeling position more accurate, reducing the probability of misjudgment, avoiding accidental damage, and further ensuring product quality.

[0034] 2. In this utility model, by setting the second guide post and the second guide sleeve, the position of the peeling knife is more fixed, avoiding displacement of the peeling knife due to long-term processing, thereby further ensuring the reliability of processing.

[0035] 3. By making the peeling blade a flip-up structure, this utility model can avoid the problem of equipment damage caused by the large thickness of the peeling blade.

[0039] 7. This utility model, by setting a micro switch working indicator light, allows for intuitive judgment of the adjustment height of the linkage plate, making operation more convenient and practical.

[0040] 8. This utility model uses a combination of a pusher screw, a slider, a groove and a pusher motor to push ceramic sheets. The pushing process is continuous and smooth, the structure is simpler and the design is more reasonable.

[0041] 9.

Detailed Implementation

[0056] The present invention will be further described below with reference to the embodiments, but this should not be construed as limiting the present invention.

[0057] Embodiments of this utility model

[0058] An automatic peeling device for square zinc oxide varistors after sintering, as shown in the attached figure. Figure 1-11 As shown, it includes an operating table 1, a peeling groove 2 on the operating table 1, a feeding port 3 at one end of the peeling groove 2, an automatic peeling machine 5 above the feeding port 3, and an automatic pushing mechanism 4 on one side of the peeling groove 2.

[0059] The automatic peeling machine 5 includes a housing 510 standing on the operating table 1, one side of the housing 510 is suspended above the peeling groove 2, and a peeling assembly and a position sensing assembly are connected inside it.

[0060] The peeling assembly includes a peeling blade 511 extending downward to the bottom of the housing 510. The peeling blade 511 is made of sharpened metal blade. The peeling blade 511 is connected to a reciprocating drive device 516, which is specifically an electric telescopic cylinder.

[0061] The position sensing component includes a linkage plate 512 extending downward to the bottom of the housing 510. The thickness of the lower end of the linkage plate 512 is less than the maximum opening width of the V-groove at the top of the gap surface of the adjacent ceramic sheet. The horizontal plane where the lower end of the linkage plate 512 is located is lower than the horizontal plane where the lower end of the peeling blade 511 is located. The linkage plate 512 and the peeling blade 511 are located on the same vertical plane, and this vertical plane is parallel to the gap surface when peeling zinc oxide pressure-sensitive ceramic sheets.

[0062] The upper end of the linkage plate 512 is connected to the guide post 517, and a micro switch is provided at the connection point; the micro switch, the automatic feeding mechanism 4 and the reciprocating drive device 516 are connected to the controller 6.

[0063] In this specific implementation, the operating table 1 needs to be fixed at a fixed position on the assembly line, and it can start working after the power is turned on. The specific working process is as follows:

[0064] First, the sintered ceramic sheet 9 is placed in the peeling groove. The automatic pusher mechanism 4 is activated to contact one end of the ceramic sheet 9 and continues to push the ceramic sheet 9 until the upper surface of the other end of the ceramic sheet contacts the lower surface of the linkage plate 512. At this time, the ceramic sheet has an upward lifting effect on the linkage plate 512. The micro switch is in the off state, the reciprocating drive device 516 is in the stopped state, and the automatic pusher mechanism 4 continuously pushes the ceramic sheet forward. The linkage plate 512 moves in the opposite direction relative to the ceramic sheet. When the bottom end of the linkage plate 512 enters the V-groove at the top of the gap surface of the adjacent ceramic sheet, since the thickness of the lower end of the linkage plate 512 is less than the maximum opening width of the V-groove, the linkage plate 512 will move downward and enter the V-groove. The downward movement distance is shown in the attached figure. Figure 10 As shown in d, the moving distance is exactly the start / stop stroke of the micro switch. At this time, the micro switch is in the on state, and the electrical signal is transmitted to the controller 6. The controller 6 first controls the automatic feeding mechanism 4 to stop working, and then controls the reciprocating drive device 516 to start working, pushing the peeling blade 511 downward to move and insert into the gap surface of the ceramic sheet, peeling off the ceramic sheet at the end. Then the reciprocating drive device 516 drives the peeling blade 511 to retract upward, completing one action. At this time, the controller 6 continues to control the automatic feeding mechanism 4 to start working, pushing the ceramic sheet forward, and the linkage plate 512 is continued to be lifted upward. The micro switch is turned off. When the next gap surface is reached, the previous action is repeated, so as to realize the continuous automatic peeling of the ceramic sheet.

[0065] Further implementation, for example, is attached. Figure 1-11 As shown, the peeling blade 511 is connected to the reciprocating drive device 516 via a second guide post 513 and a connecting rod 515, wherein the second guide post 513 is slidably connected in a second guide sleeve 514 inside the housing 510. The second guide post 513 and the second guide sleeve 514 fit tightly together to prevent the peeling blade 511 from shifting on the horizontal plane.

[0066] Further implementation, for example, is attached. Figure 1-11 As shown, the lower end of the guide post 513 has a square inner hole 529 that is recessed upwards. The width of the square inner hole 529 is greater than the thickness of the peeling blade 511. The upper end of the peeling blade 511 is connected to the side of the square inner hole 529 away from the feed port 3 via a rotating shaft 530. A spring 531 is provided between the other side and the peeling blade 511.

[0067] In this embodiment, the peeling blade 511 can be made of a 1-2mm thick blade with a sharpened lower end. When the peeling blade 511 is not inserted into the gap of the ceramic sheet, under the action of the spring 531, the peeling blade 511 remains vertically downward, and the longitudinal surface of its cutting edge overlaps with the longitudinal surface of the bottom end of the linkage plate 512, ensuring that during peeling, the insertion position of the peeling blade 511 is exactly within the gap surface sensed by the linkage plate 512. However, when the peeling blade 511 is inserted into the gap, due to its thickness, it will squeeze the ceramic sheet to both sides. The side that has not been peeled is fixed in position and has no room to move, thus easily causing damage to the peeling blade 511 or the ceramic sheet. In this embodiment, after the peeling blade 511 is connected by the rotating shaft 530, the peeling blade 511 can be deflected in the peeling direction to avoid squeezing the unpeeled ceramic sheet. At the same time, as shown in the attached... Figure 11 As shown, the flipped peeling blade 511 pushes the ceramic sheet away, making it easier for it to peel off and detach. When the peeling blade 511 moves upward away from the gap, it returns to its original position in the spring 531.

[0068] Further implementation, for example, is attached. Figure 1-11 As shown, a strip roller 528 is slidably connected to the lower end of the linkage plate 512. The axial direction of the strip roller 528 is parallel to the gap surface when peeling the zinc oxide pressure-sensitive ceramic sheet. In this embodiment, the strip roller 528 is similar to the ballpoint pen ball, embedded in the bottom end of the linkage plate 512, and can slide but will not fall off.

[0069] Further implementation, for example, is attached. Figure 1-11 As shown, the lower end of the guide post 517 has an upward-facing T-shaped inner hole 524 in the middle. The upper end of the linkage plate 512 is a T-shaped structure that mates with the T-shaped inner hole 524. A spring 525 is provided between the top of the linkage plate 512 and the top of the T-shaped inner hole 524. Contacts A526 and B527 are respectively provided on the lower side of the top edge of the linkage plate 512 and the lower side of the top edge of the T-shaped inner hole 524. The spring 525, contact A526, and contact B527 constitute the micro switch. Contacts A526 and B527 are respectively connected to the controller 6.

[0070] In this embodiment, when the linkage plate 512 is pushed upward, the compression spring 525 is compressed, and contacts A526 and B527 are disconnected. When the lower end of the linkage plate 512 enters the gap surface of the ceramic sheet, the spring 525 pushes the linkage plate 512 downward, causing contacts A526 and B527 to contact, forming an electrical signal and transmitting it to the controller 6.

[0071] Further implementation, for example, is attached. Figure 1-11As shown, the guide post 517 is slidably connected to the guide sleeve 518 inside the housing 510. The top of the guide post 517 is provided with a vertically downward internal threaded hole, and an adjusting screw 519 is threadedly connected inside it. The top of the adjusting screw 519 is provided with a bevel gear 520. A bevel gear 521 is meshed on one side of the bevel gear 520. The central shaft of the bevel gear 521 extends out of the housing 510 and is connected to an adjusting handle 522.

[0072] When the height of the ceramic sheet changes, the adjusting handle 522 is rotated, which drives the adjusting screw 519 to rotate. The adjusting screw 519 is fixed in the longitudinal direction. Therefore, the guide post 517 will move up and down relative to the adjusting screw 519, thereby driving the linkage plate 512 to move up and down, so as to adjust the height of the linkage plate 512 to meet the peeling requirements of ceramic sheets of different heights.

[0073] Further implementation, for example, is attached. Figure 1-11 As shown, the housing 510 is provided with a micro switch working indicator light 523, which is connected to the controller 6.

[0074] In this embodiment, the microswitch indicator light 523 is synchronized with the microswitch's on / off state. When the microswitch is on, the microswitch indicator light 523 is constantly lit; when the microswitch is off, the microswitch indicator light 523 is off. When adjusting the height of the linkage plate 512, the stacked ceramic sheets must first be placed below the linkage plate 512. The linkage plate 512 is then adjusted to the lowest point of the V-groove on the gap surface and brought into contact with it, while ensuring that the microswitch indicator light 523 is lit. When the microswitch indicator light 523 is off, it indicates that the guide post 517 has moved too far downwards, causing the microswitch to disengage. Therefore, ensuring that the lowest point of the linkage plate 512 enters the V-groove on the gap surface and that the microswitch indicator light 523 is constantly lit indicates that the device is in a working state.

[0075] Further implementation, for example, is attached. Figure 1-11 As shown, the automatic feeding mechanism 4 includes a slide groove 41 located on one side of the peeling groove 2 and parallel to it. A feeding screw 42 parallel to the peeling groove 2 is provided in the slide groove 41. A slider 43 is threadedly connected to the feeding screw 42. The slider 43 is in close contact with the inner wall of the slide groove 41. A crank arm 45 is provided on the side of the slider 43 near the peeling groove 2. The end of the crank arm 45 extends into the peeling groove 2. A feeding motor 44 is connected to one end of the feeding screw 42. The feeding motor 44 is connected to the controller 6.

[0076] When pushing ceramic pieces, the pusher motor 44 drives the pusher screw 42 to rotate, and the slider 43 moves on the pusher screw 42 to push the ceramic pieces. When resetting, the pusher motor 44 simply reverses.

[0077] Further implementation, for example, is attached. Figure 1-11 As shown, a V-shaped limiting groove 46 is provided on the side of the crank arm 45 near the automatic peeling machine 5. A limiting piece 7 is provided on each side of the peeling groove 2 near the feeding port 3. Multiple springs 8 are provided between the back of the limiting piece 7 and the side wall of the peeling groove 2. The line connecting the midpoint of the vertical line connecting two limiting pieces 7 and the intersection point of the V-shaped limiting groove 46 is parallel to the length direction of the peeling groove 2. When the width of the ceramic sheet is less than the width of the peeling groove 2, the V-shaped limiting groove 46 and the limiting piece 7 work together to keep the ceramic sheet in the center position.

[0078] Further implementation, for example, is attached. Figure 1-11 As shown, the entrance end of the limiting piece 7 has an outwardly flipped arc-shaped surface.
