Description

Technical Field

[0001] This utility model belongs to the field of ceramic substrates and relates to ceramic substrate testing technology, specifically a defect detection device for ceramic substrates. Background Technology

[0002] Ceramic substrates, as an important material, have wide applications in electronics, optoelectronics, and energy. Their excellent performance and stability make them an ideal choice for various electronic and optoelectronic devices. Common ceramic substrate materials include alumina, aluminum nitride, silicon carbide, and silicon nitride, which are differentiated in their application across various engineering fields based on their varying performance characteristics such as thermal conductivity, bending strength, and breakdown voltage.

[0003] Currently, Chinese Patent Publication No. CN117753690A proposes a self-positioning ceramic substrate defect detection device and method. It mainly achieves rapid detection of internal defects in ceramic substrates by setting up a detection device with a needle-plate electrode structure on a detection platform and utilizing the bonding between two plates under a high voltage electric field.

[0004] However, the above-mentioned device still has certain drawbacks: for example, after the test is completed, a conveyor belt needs to be run so that the moving stage carrying the tested ceramic substrate can move to the next process to complete the classification operation. Then the moving stage is reset and the test is repeated. This process takes a long time and is difficult to meet the needs of batch testing.

[0005] Therefore, a defect detection device for ceramic substrates is needed to solve the above problems. Utility Model Content

[0006] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a defect detection device for ceramic substrates, enabling the simultaneous sorting and loading of ceramic substrates at the detection station after inspection. This shortens the time wasted during the sorting process, thereby increasing the detection rate and meeting the application requirements of batch inspection. This invention employs an adsorption extraction component comprising two adsorption handles and a rotating lifting module. A conveyor table and a placement component are located on either side of the adsorption extraction component. The two adsorption handles can move between the conveyor table and the detection component, and between the detection component and the placement component. Therefore, after the detection component completes the inspection of the ceramic substrate, one adsorption handle can output the inspected ceramic substrate from the detection component to the placement component, while the other adsorption handle can place the ceramic substrate from the conveyor table onto the detection component. This allows the device to simultaneously sort the inspected ceramic substrates and load them at the detection station, thereby shortening the time wasted during the sorting process, increasing the detection rate, and meeting the application requirements of batch inspection.

[0007] To achieve the above objectives, the first aspect of this utility model provides a defect detection device for ceramic substrates, including a machine base, a stand, a conveyor, a placement assembly, a detection assembly, and an adsorption extraction assembly.

[0008] The support frame is fixedly installed on the machine base;

[0009] The conveyor table is disposed on one side of the upper surface of the machine platform;

[0010] The placement assembly is located on the other side of the upper surface of the machine platform and is used to store qualified ceramic substrates and unqualified ceramic substrates respectively.

[0011] The detection component is disposed on the inner side wall of the stand;

[0012] The adsorption and extraction assembly is located in the middle of the lower surface of the stand and includes two interconnected adsorption handles and a rotary lifting module.

[0013] The rotary lifting module is fixedly connected to the connection of the two suction handles, and is used to control the movement of the two suction handles, so that while one suction handle moves between the conveyor table and the detection component, the other suction handle moves between the detection component and the placement component.

[0014] Furthermore, the rotating lifting module can drive the two suction handles to be positioned between the conveyor and the detection component, and between the detection component and the placement component, respectively.

[0015] Furthermore, the rotary lifting module includes a cylinder and a rotary motor;

[0016] The cylinder is used to control the raising and lowering of the suction handle;

[0017] The rotary motor is used to control the rotation of the suction handle.

[0018] Furthermore, the placement assembly includes a rotating disk, a qualified material bin, and a non-qualified material bin;

[0019] The rotary disk is mounted on the surface of the machine base by a rotary motor;

[0020] The qualified material bins and the unqualified material bins are symmetrically arranged on the rotating disk, and both can rotate to be directly below the suction handle.

[0021] Furthermore, it also includes the controller;

[0022] The controller is electrically connected to the detection component and the rotating motor;

[0023] The controller controls the operation of the rotary motor according to the detection results of the detection component on the ceramic substrate, so that the qualified material box or the unqualified material box is located directly below the adsorption handle of the ceramic substrate after adsorption detection.

[0024] Furthermore, the conveyor platform has a built-in stepper motor.

[0025] Compared with the prior art, the beneficial effects of this utility model are:

[0026] By setting up an adsorption extraction component including two adsorption handles and a rotating lifting module, and placing the conveyor and placement components on both sides of the adsorption extraction component, and allowing the two adsorption handles to move between the conveyor and the detection component and between the detection component and the placement component respectively, after the detection component completes the detection of the ceramic substrate, one adsorption handle can output the detected ceramic substrate from the detection component to the placement component, while the other adsorption handle can place the ceramic substrate on the conveyor onto the detection component. This allows the device to complete the loading operation of the ceramic substrate at the detection station while performing the classification operation on the detected ceramic substrate, thereby shortening the time wasted in the classification process of the detected ceramic substrate, improving the detection speed, and meeting the needs of batch detection applications.

[0037] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0038] Please see Figures 1 to 7 The first aspect of this utility model provides a defect detection device for ceramic substrates, including a machine base 1, a stand 2, a conveyor 3, a placement component 4, a detection component 5, and an adsorption extraction component 6.

[0039] The support frame 2 is fixedly installed on the machine base 1.

[0040] Furthermore, the conveyor 3 is disposed on one side of the upper surface of the machine base 1 for conveying the ceramic substrate to be tested, while the placement assembly 4 is disposed on the other side of the upper surface of the machine base 1 for storing qualified ceramic substrates and unqualified ceramic substrates respectively.

[0041] In this embodiment, the detection component 5 is disposed on the inner side wall of the stand 2. It should be noted that the detection component 5 is located between the conveyor table 3 and the placement component 4.

[0042] In addition, the adsorption extraction component 6 is located in the middle of the lower surface of the stand 2, and includes two interconnected adsorption handles 61 and a rotary lifting module 62.

[0043] The rotary lifting module 62 is fixedly connected to the connection of the two suction handles 61, and is used to control the movement of the two suction handles 61, so that while one of the suction handles 61 moves between the conveying table 3 and the detection component 5, the other suction handle 61 moves between the detection component 5 and the placement component 4.

[0044] It should be noted that when the adsorption handle 61 moves between the conveyor 3 and the detection component 5, it conveys the ceramic substrate to the detection component 5. When the adsorption handle 61 moves between the detection component 5 and the placement component 4, it outputs the detected ceramic substrate to the placement component 4, thus completing the sorting operation.

[0045] In summary, this device, by setting up an adsorption extraction component 6 including two adsorption handles 61 and a rotary lifting module 62, and placing the conveyor table 3 and the placement component 4 on both sides of the adsorption extraction component 6, allows the two adsorption handles 61 to move between the conveyor table 3 and the detection component 5, and between the detection component 5 and the placement component 4, respectively. Therefore, after the detection component 5 completes the detection of the ceramic substrate, one adsorption handle 61 can output the detected ceramic substrate from the detection component 5 to the placement component 4, while the other adsorption handle 61 can place the ceramic substrate on the conveyor table 3 onto the detection component 5. This allows the device to complete the loading operation of the ceramic substrate at the detection station while performing the classification operation on the detected ceramic substrate, thereby shortening the time wasted in the classification process of the detected ceramic substrate, improving the detection speed, and meeting the needs of batch detection applications.

[0046] It should be noted that the detection component 5 proposed in this embodiment is the detection device mentioned in the background art above. The detection device mainly includes two plates, and the two plates can move in the vertical direction. Therefore, the adsorption handle 61 will not interfere with the detection device during the rotation process, so as to ensure the stability of the overall device operation.

[0047] In a further embodiment, to ensure that the setting of the adsorption handle 61 does not interfere with the operation of the detection component 5, the rotary lifting module 62 is further defined.

[0048] Specifically, such as Figure 4 As shown, the rotating lifting module 62 can drive the two suction handles 61 to be positioned between the conveyor table 3 and the detection component 5, and between the detection component 5 and the placement component 4, respectively. Figures 5 to 7 As shown, when the detection component 5 completes the detection, the rotary lifting module 62 drives the two suction handles 61 to rotate along the Va direction. At this time, one suction handle 61 is positioned on the conveyor table 3, completing the extraction of the ceramic substrate, while the other suction handle 61 is positioned on the detection component 5, completing the extraction of the ceramic substrate after detection. Then, the rotary lifting module 62 drives the two suction handles 61 along the Vb direction until one suction handle 61 is positioned on the detection component 5, completing the placement of the ceramic substrate, while the other suction handle 61 is positioned on the placement component 4, completing the classification of the ceramic substrate after detection. After completing the above operations, the rotary lifting module 62 repositions the ceramic substrate back to its normal position (e.g., ...). Figure 4 As shown in the figure, at this time, the detection component 5 performs the detection of the next ceramic substrate, thereby realizing the function of batch detection of ceramic substrates.

[0049] In this embodiment, the rotary lifting module 62 includes a cylinder and a rotary motor. The cylinder is used to control the lifting and lowering of the suction handle 61, and the rotary motor is used to control the rotation of the suction handle 61.

[0050] In other embodiments, a specific placement component 4 is proposed to better classify the inspected ceramic substrates. Specifically, the placement component 4 includes a rotating disk 41, a qualified material bin 42, and a defective material bin 43.

[0051] The rotating disk 41 is mounted on the surface of the machine base 1 by a rotating motor. The qualified material box 42 and the unqualified material box 43 are symmetrically arranged on the rotating disk 41, and both can rotate to be directly below the suction handle 61.

[0052] In a further embodiment, the defect detection device for the ceramic substrate also includes a controller 7.

[0053] The controller 7 is electrically connected to the detection component 5 and the rotary motor. The controller 7 controls the rotary motor to operate based on the detection results of the ceramic substrate by the detection component 5, positioning either the qualified material bin 42 or the unqualified material bin 43 directly below the adsorption handle 61 of the ceramic substrate after adsorption testing. In other words, the controller 7 obtains the information detected by the detection component 5 on the ceramic substrate and controls whether the rotary motor operates. For example, when the detection component 5 detects the ceramic substrate as qualified, the controller 7 does not operate, ensuring that the qualified material bin 42 is directly below the adsorption handle 61 of the ceramic substrate after adsorption testing. Conversely, when the detection component 5 detects the ceramic substrate as unqualified, the controller 7 controls the unqualified material bin 43 to rotate to be directly below the adsorption handle 61 of the ceramic substrate after adsorption testing. During this process, the adsorption handle 61 does not need to perform any additional actions, allowing the adsorption extraction component 6 to simply rotate and move up and down, thus avoiding potential malfunctions due to the numerous actions performed by the adsorption extraction component 6.

[0054] It should also be noted that the conveyor 3 is equipped with a stepper motor, which is used to intermittently supply ceramic substrates. The interval time is the same as the time required for the adsorption handle 61 to reciprocate between the conveyor 3 and the detection component 5, so as to improve the coordination between the overall devices.

[0055] The above embodiments are only used to illustrate the technical methods of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of this utility model without departing from the spirit and scope of the technical methods of this utility model.
