Description

Technical Field

[0001] This utility model relates to the field of ceramic heating element processing technology, and in particular to a cutting device for processing ceramic heating elements. Background Technology

[0002] Ceramic heating elements are a new generation of medium- and low-temperature heating elements produced by printing resistance paste directly onto Al2O3 alumina ceramic green blanks, firing them at a high temperature of around 1600℃, and then processing them with electrodes and leads. They are a new generation of products following alloy heating wires and PTC heating elements, and are widely used in many fields that require medium- and low-temperature heating, such as daily life, industrial and agricultural technology, communications, medical care, and environmental protection.

[0003] A ceramic sheet cutting device is disclosed in document CN221809482U. This device, through the cooperation of a top plate and a height adjustment mechanism, can drive a pressure reducing plate to press the ceramic sheet being cut. This method can be applied to fixing ceramic sheets of various sizes, and is simple, quick, and widely applicable. In contrast, the aforementioned prior art only supports the fixing, cutting, and unloading of a single ceramic sheet. After each processing, manual resetting is required, followed by removing the ceramic sheet and placing another to be cut. This results in a high proportion of idle time and low production efficiency. Utility Model Content

[0004] The purpose of this invention is to solve the problems existing in the prior art by proposing a cutting device for processing ceramic heating elements.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A cutting device for processing ceramic heating elements includes a processing table and a laser cutting device fixedly mounted on the processing table. The processing table is equipped with a rotating mechanism and a feeding hopper. The rotating mechanism is equipped with four adsorption platforms arranged in a circular array, one of which is positioned corresponding to the feeding hopper.

[0007] The adsorption platform is equipped with a suction pump that is connected to it on its side. The top of the adsorption platform is equipped with several evenly distributed ventilation protrusions. Each ventilation protrusion has an air hole that is connected to the inside of the adsorption platform. A block is placed inside the ventilation protrusion to seal the air hole.

[0008] Preferably, the rotating mechanism includes a four-wing rotary table rotatably mounted on the worktable, with four support columns and cylinders fixedly connected to the four-wing rotary table in a circumferential array, the adsorption platform being hinged to the top of the support columns, and the cylinders being hinged between the adsorption platform and the rotary table.

[0009] Preferably, a motor is mounted on the workbench, a drive wheel is fixedly connected to the output shaft of the motor, a driven wheel is fixedly connected to the four-wing rotary table, and a synchronous belt is provided between the drive wheel and the driven wheel for transmission.

[0010] Preferably, the diameter of the drive wheel is one-quarter of the diameter of the driven wheel, and the motor is a stepper motor.

[0011] Preferably, a positioning block is fixedly connected to one corner of the top of the adsorption platform, and the positioning block is an "L" shaped component.

[0012] Preferably, the venting protrusion is a metal component, and the plug is a magnetic component, wherein the plug can be adsorbed into the venting protrusion to seal the vent.

[0013] Preferably, a sealing ring is fitted at the bottom of the block, the sealing ring abuts against the inner wall of the air hole, and a pull ring is fixedly connected to the top of the block.

[0014] Preferably, an annular pad is fixedly connected to the top of the venting boss. The annular pad is a fluororubber material component and is glued to the venting boss using high-temperature resistant adhesive.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0016] 1. In this application, four adsorption tables are arranged in a circular array and rotate periodically with the rotating mechanism to achieve continuous operation of four stations: loading, cutting, unloading, and transition. This enables parallel operation of multiple stations, reduces downtime, and allows for seamless connection between loading, processing, and unloading. It is suitable for mass production and improves production efficiency.

Detailed Implementation

[0025] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0027] like Figure 1-6 As shown, this utility model provides a cutting device for processing ceramic heating elements, including a processing table 100 and a laser cutting device 200 fixedly installed on the processing table 100. The laser cutting device 200 adopts the prior art to realize the three-dimensional movement of the laser cutter. It can be the laser cutting device 200 disclosed in CN119589144A. Other laser cutting instruments that meet the requirements of this application can also be used, which will not be described in detail here. A rotating mechanism 300 and a feeding hopper 400 are installed on the processing table 100. Four adsorption platforms 500 are arranged in a circular array on the rotating mechanism 300, and the position of one of the adsorption platforms 500 corresponds to the feeding hopper 400.

[0028] The adsorption platform 500 is fixedly installed on the side and connected to the air pump 600. The top of the adsorption platform 500 is fixedly installed with several evenly distributed ventilation protrusions 501. The ventilation protrusions 501 are provided with air holes 502 that communicate with the interior of the adsorption platform 500. A block 503 that blocks the air holes 502 is placed in the ventilation protrusions 501.

[0029] In this embodiment, the rotating mechanism 300 includes a four-wing rotary table 301 rotatably mounted on the workbench. Four support columns 302 and cylinders 303 are fixedly connected to the four-wing rotary table 301 in a circular array. The adsorption table 500 is hinged to the top of the support columns 302, and the cylinders 303 are hinged between the adsorption table 500 and the rotary table.

[0030] Specifically, the four adsorption tables 500 rotate periodically with the four-wing rotary table 301, passing through the loading station, laser cutting station and unloading station in sequence. After the current adsorption table 500 completes processing, the rotary table rotates 90° and the next station arrives at the corresponding position, realizing station switching and forming a continuous processing flow. Multiple stations operate in parallel, reducing downtime. The loading, processing and unloading are seamlessly connected, which is suitable for mass production.

[0031] In this embodiment, a motor 304 is mounted on the workbench, a drive wheel 305 is fixedly connected to the output shaft of the motor 304, a driven wheel 306 is fixedly connected to the four-wing rotary table 301, a synchronous belt 307 is provided between the drive wheel 305 and the driven wheel 306 for transmission, the diameter of the drive wheel 305 is one-quarter of the diameter of the driven wheel 306, and the motor 304 is a stepper motor 304.

[0032] Specifically, motor 304 controls the rotation of drive wheel 305, which drives driven wheel 306 via synchronous belt 307. Stepper motor 304 eliminates the need for encoder feedback, simplifying system complexity. It consumes power only during rotation and maintains zero power consumption when stationary. The diameter ratio of drive wheel 305 to driven wheel 306 is 1:4, and the transmission ratio is 4:1. For every revolution of motor 304, driven wheel 306 rotates 90°, thus achieving workstation switching.

[0033] In this embodiment, a positioning block 504 is fixedly connected to one corner of the top of the adsorption stage 500. The positioning block 504 is an "L" shaped component.

[0034] Specifically, the ceramic sheet is placed on the adsorption table 500, close to the "L"-shaped positioning block 504. The positioning block 504 restricts the position of the ceramic sheet and positions it before it is adsorbed. The operator does not need to precisely align the ceramic sheet, which increases the feeding speed and prevents it from shifting during cutting and causing it to be scrapped.

[0035] In this embodiment, the venting boss 501 is a metal component, and the blocking block 503 is a magnetic component. The blocking block 503 can be adsorbed into the venting boss 501 to block the air hole 502. A sealing ring 505 is sleeved on the bottom of the blocking block 503, and the sealing ring 505 abuts against the inner wall of the air hole 502. A pull ring 506 is fixedly connected to the top of the blocking block 503.

[0036] Specifically, depending on the size of the ceramic plate, the block 503 in the ventilation protrusion 501 covered by the ceramic plate is removed. The pull ring 506 facilitates the removal of the block 503, keeping the air hole 502 of the corresponding ventilation protrusion 501 open. The block 503 in the ventilation protrusion 501 not covered by the ceramic plate seals the corresponding air hole 502. The sealing ring 505 improves the sealing effect. The block 503 in the covered area is selectively removed according to the size of the ceramic plate, so that the adsorption negative pressure only acts on the actual covered area of ​​the ceramic plate, avoiding ineffective air extraction, ensuring that the adsorption force is concentrated on the effective contact surface, reducing pressure loss caused by edge leakage, and improving adsorption stability.

[0037] In this embodiment, an annular pad 507 is fixedly connected to the top of the venting boss 501. The annular pad 507 is a fluororubber material component and is attached to the venting boss 501 with high-temperature resistant adhesive.

[0038] Specifically, the fluororubber ring gasket 507 is heat resistant up to 250℃ and is attached to the top of the ventilated boss 501 to buffer the contact with the workpiece. The soft gasket prevents the ceramic sheet from being scratched, increases friction to improve the positioning effect, and is suitable for the local high temperature environment of laser cutting.

[0039] How to use and how to work this device:

[0040] When using this device

[0041] First, the operator places the ceramic sheet on the adsorption table 500, close to the "L"-shaped positioning block 504. According to the size of the ceramic sheet, the operator selectively moves the block 503 in the coverage area, so that the air hole 502 in the corresponding ventilation protrusion 501 is opened. The positioning block 504 achieves rapid coarse positioning, reducing manual adjustment time. The block 503 selectively opens the air hole 502 to ensure that the negative pressure adsorption only acts on the area covered by the ceramic sheet.

[0042] Secondly, when the air pump 600 starts, the air hole 502 generates negative pressure, which adsorbs the ceramic sheet through the open air hole 502. The block 503 with the closed air hole 502 is sealed by the sealing ring 505 to avoid ineffective air extraction and reduce pressure loss.

[0043] Subsequently, motor 304 controls drive wheel 305 to rotate, and drives four-wing rotary table 301 to rotate 90° through synchronous belt 307. After the current station adsorption table 500 rotates, it enters the laser cutting area. The laser cutting head of laser cutting equipment 200 vertically irradiates the surface of ceramic sheet, and the laser cutting head cuts ceramic sheet according to preset path.

[0044] Finally, during the cutting process, ceramic sheets continue to be placed and adsorbed at the previous station. After cutting, the rotary table rotates to the unloading station, where the air pump 600 stops and the air pump starts to lift the adsorption table 500. The cut ceramic sheets slide into the unloading hopper 400 for sorting and subsequent processes. The other stations repeat the above process, realizing continuous operation of four stations: loading, cutting, transition, and unloading. Multiple stations can operate in parallel, reducing downtime. The loading, processing, and unloading are seamlessly connected, making it suitable for mass production.

[0045] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
