Description

Technical Field

[0001] This utility model relates to the field of ceramic sheet clamping technology, and in particular to an aluminum nitride ceramic sheet clamping device. Background Technology

[0002] Aluminum nitride ceramic sheets are increasingly widely used in many fields such as electronics and machinery due to their advantages such as high thermal conductivity, good electrical insulation, and mechanical properties. However, the handling of aluminum nitride ceramic sheets during their production, processing, and transportation presents numerous challenges.

[0003] Traditional gripping devices mostly use mechanical grippers. Although this method can achieve the gripping function, aluminum nitride ceramic sheets are brittle and their surfaces are easily scratched. During the gripping process, the mechanical grippers come into direct contact with the ceramic sheets, which can easily cause scratches and damage to their surfaces, seriously affecting the quality and performance of the ceramic sheets and leading to a decrease in product yield.

[0004] Meanwhile, conventional gripping devices often lack flexible designs for the characteristics of aluminum nitride ceramic sheets, making it difficult to accurately and stably grip ceramic sheets of different shapes and sizes. They are inadequate when dealing with complex production needs. Moreover, traditional gripping devices have complex structures and the assembly and connection between components are not convenient, which not only increases the manufacturing cost and maintenance difficulty of the device, but also affects production efficiency. Utility Model Content

[0005] The purpose of this invention is to solve the problem of accurately and stably gripping ceramic sheets of different shapes and sizes in the prior art, and to propose an aluminum nitride ceramic sheet gripping device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An aluminum nitride ceramic sheet gripping device includes a first gripper and a second gripper. Both the first gripper and the second gripper consist of an airflow seat and a gripping plate inserted thereon. The gripping plates on the first gripper and the second gripper are complementary in position. When the first gripper and the second gripper are close to each other, the gripping plates on the first gripper and the second gripper are interlocked in a dogtooth pattern. The airflow seat includes a base and a cover. Multiple airflow branch pipes are equidistantly inserted in the base. Multiple insertion holes for connecting the gripping plates are opened on the cover. When the cover is assembled with the base, its airflow branch pipes are connected to the insertion holes. The gripping plates have built-in air channels. When the gripping plates are assembled with the cover, the air channels are connected to the insertion holes. Air holes communicating with the air channels are opened on the side of the gripping plates.

[0008] Preferably, the base has a receiving cavity, and its airflow branch pipe is located in the receiving cavity and penetrates the lower surface of the base. The bottom of the base is provided with a main air pipe, and the airflow branch pipe is connected to the main air pipe. One end of the main air pipe is connected to a negative pressure vacuum pump. The negative pressure vacuum pump is used to draw out and form a negative pressure, so that the clamping plate adsorbs the aluminum nitride ceramic sheet through the air hole.

[0009] Preferably, a positioning groove is provided at the edge of the upper surface of the base, and a protrusion is provided at the edge of the lower surface of the corresponding cover to fit the positioning groove. Threaded knobs are installed at the four corners of the upper surface of the base and the positioning groove, and threaded holes are provided at the four corners of the lower surface of the cover for the threaded knobs to be threaded into.

[0010] Preferably, the lower surface of the base is provided with pads at both ends, and the pads are provided with round holes, through which the main air pipe is fixed to the pads.

[0011] Preferably, the lower surface of the cover box has multiple branch pipe insertion holes in the center. When the cover box is assembled with the base, its airflow branch pipe is inserted into the branch pipe insertion hole. The upper end of the airflow branch pipe has a docking hole, and the airflow branch pipe, docking hole and insertion hole are connected.

[0012] Preferably, both the mating hole and the insertion hole are rectangular structures, and the width of the mating hole is smaller than the width of the insertion hole. The branch pipe insertion hole is circular and located at the center of the mating hole.

[0013] Preferably, one side of the gripping plate is integrally connected with a plate-shaped fork, the fork is horizontally arranged, the air passage is opened along the central axis of the gripping plate and the fork, and multiple air holes are opened at equal intervals along the direction of the air passage.

[0014] Preferably, the clamping plate comprises a first clamping piece and a second clamping piece, and the first clamping piece and the second clamping piece have the same shape. The air passage is opened on the side where the first clamping piece and the second clamping piece are in contact. The bottom of the clamping plate is connected to a plug-in block, and the plug-in block has a through hole in the center that communicates with the air passage.

[0015] Preferably, the two sides of the lid are connected to the liner by screws, and the liner has the same shape as the clamping plate.

[0016] Compared with the prior art, the present invention provides an aluminum nitride ceramic sheet clamping device, which has the following beneficial effects:

[0017] 1. This aluminum nitride ceramic sheet clamping device uses an airflow branch pipe inside the base, connected to an external negative pressure vacuum pump to create negative pressure, and utilizes the air holes on the clamping plate to adsorb aluminum nitride ceramic sheets. This non-contact adsorption clamping method, compared with traditional mechanical clamping, avoids scratching and damage to the surface of the ceramic sheet, and is especially suitable for aluminum nitride ceramic sheets with fragile and easily damaged surfaces.

[0018] 2. This aluminum nitride ceramic sheet gripping device, through the built-in air channels in the gripping plate and the equidistantly spaced air holes along the air channel direction, enables a more uniform distribution of adsorption force on the ceramic sheet, ensuring firm adsorption and preventing the ceramic sheet from falling off or being damaged due to uneven force. The bifurcated structure further increases the gripping area and adsorption range, and the gripping plate, composed of a first clamping piece and a second clamping piece, facilitates the opening of the air channels and the manufacturing and maintenance of the gripping plate. The design of the plug-in block and its central through hole facilitates the plug-in connection between the gripping plate and the cover box, as well as the air channel connection.

[0019] 3. This aluminum nitride ceramic sheet clamping device uses the complementary positions of the clamping plates on the first and second clamping devices, which interlock in a dog-tooth pattern when close together. This design can better fit the shape of the aluminum nitride ceramic sheet, improve the stability and accuracy of clamping, and adapt to the clamping needs of ceramic sheets of different shapes and sizes. Furthermore, a positioning groove is opened on the edge of the upper surface of the base, and a protrusion is provided on the edge of the lower surface of the cover to match it. Threaded knobs are installed at the four corners of the base to cooperate with the screw holes of the cover, which facilitates accurate assembly of the cover and the base, ensures correct connection between the airflow branch pipe and the insertion hole, and enhances the stability of the overall structure.

[0020] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model can effectively avoid damage to the surface of aluminum nitride ceramic sheets, and can flexibly and stably clamp ceramic sheets of different specifications. It is also a simple clamping device that is easy to assemble and maintain. Attached Figure Description

Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0031] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0032] See Figure 1 and Figure 2 This is a structural diagram of an aluminum nitride ceramic sheet gripping device in this embodiment. The device mainly consists of a first gripper 100 and a second gripper 200, which have similar structures and cooperate with each other to achieve stable gripping of the aluminum nitride ceramic sheet. Furthermore, the gripping plates 103 on the first gripper 100 and the second gripper 200 are complementary in position. When the first gripper 100 and the second gripper 200 are close to each other, the gripping plates 103 on both are staggered in a dog-tooth pattern. This staggered distribution design can ensure effective gripping of the aluminum nitride ceramic sheet while avoiding mutual interference between the two grippers during the gripping process, thereby improving the stability and reliability of the gripping operation.

[0033] See Figure 3 and Figure 5This is a schematic diagram of the gripper structure in this embodiment. Both the first gripper 100 and the second gripper 200 in this embodiment consist of an airflow seat and a gripping plate 103. The airflow seat is a key component providing adsorption power and connection support. The gripping plate 103 directly contacts the aluminum nitride ceramic sheet and performs the adsorption and gripping action. The base 101 is the basic support component of the airflow seat, and has an internal receiving cavity 1012. Multiple airflow branch pipes 1015 are equidistantly arranged within the receiving cavity 1012, extending from the lower surface of the base 101. A main air pipe 1014 is located at the bottom of the base 101, and all airflow branch pipes 1015 are connected to the main air pipe 1014. One end of the main air pipe 1014 is connected to a negative pressure vacuum pump, model R29.655, with a measurement range of 0-760m. The adjustable range is 0-400 mmHg. The power supply is 120 / 240Vac±20%. Negative pressure generated by a vacuum pump allows gas to be drawn in through the air holes 1035 of the clamping plate 103, thus achieving the adsorption of aluminum nitride ceramic sheets. The lower surface of the base 101 has feet at both ends, each with a round hole through which the main air pipe 1014 is fixed, ensuring a stable connection of the main air pipe 1014 and the stability of the entire device during operation. The cover box 102 is located above the base 101, and its sides are connected to liner plates 104 by screws. The liner plates 104 have the same shape as the clamping plate 103, facilitating the positioning and guidance of the clamping plate 103 during clamping. The cover box 102 has multiple insertion holes 1023 for connecting the clamping plate 103. Figure 4 In this embodiment, a protrusion is provided at the lower surface edge of the lid 102, which matches the positioning groove 1011 opened at the upper surface edge of the base 101, achieving precise horizontal positioning of the lid 102 and the base 101. Simultaneously, threaded knobs 1013 are fitted at the four corners of the positioning groove 1011 on the upper surface of the base 101, and corresponding screw holes are opened at the four corners of the lower surface edge of the lid 102. The lid 102 is firmly fixed to the base 101 through the threaded connection between the threaded knobs 1013 and the screw holes. Furthermore, in... Figure 6 In this embodiment, the lower surface of the cover 102 is provided with a plurality of branch pipe insertion holes 1021. When the cover 102 is assembled with the base 101, the airflow branch pipe 1015 is inserted into the branch pipe insertion hole 1021. The upper end of the airflow branch pipe 1015 is provided with a docking hole 1022. The airflow branch pipe 1015, the docking hole 1022 and the insertion hole 1023 are interconnected. The docking hole 1022 and the insertion hole 1023 are both designed as rectangular structures. The width of the docking hole 1022 is smaller than the width of the insertion hole 1023. This design is conducive to the directional flow of gas in the channel and the stable insertion of the clamping plate 103. The branch pipe insertion hole 1021 is circular and located at the center of the docking hole 1022 to ensure the coaxiality and sealing of the airflow branch pipe 1015 after insertion.

[0034] See Figure 7 and Figure 8 This is a schematic diagram of the clamping plate structure in this embodiment. In this embodiment, a horizontally arranged plate-shaped bifurcated structure is integrally connected to one side of the clamping plate 103. The air passage 1034 is opened along the central axis of the clamping plate 103 and the bifurcation, and multiple air holes 1035 are equally spaced along the direction of the air passage 1034 to ensure uniform distribution of adsorption force when clamping the aluminum nitride ceramic sheet. The clamping plate 103 is composed of a first clamping plate 1031 and a second clamping plate 1032, both of which have the same shape. The air passage 1034 is also shown in the diagram. 034 is located on the side where the first clamping piece 1031 and the second clamping piece 1032 fit together. This design facilitates the processing and maintenance of the air passage 1034. The bottom of the clamping plate 103 is connected to the insertion block 1033, and the insertion block 1033 has a through hole in the center that communicates with the air passage 1034. When the clamping plate 103 is assembled with the cover box 102, the air passage 1034 communicates with the insertion hole 1023 on the cover box 102 through the through hole of the insertion block 1033, thereby forming a complete gas passage.

[0035] In summary, this aluminum nitride ceramic sheet gripping device, through its reasonable structural design and the principle of negative pressure adsorption, achieves efficient and stable gripping of aluminum nitride ceramic sheets, and has significant application value in related ceramic sheet processing and handling fields.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
