Description

Technical Field

[0001] The invention belongs to the technical field of thermal printers, and in particular relates to a thin-sheet vacuum material taking suction head made of ceramic material. Background Art

[0002] The working principle of a thermal printer is that a semiconductor heating element is installed on the print head. After the print head is heated and contacts the thermal printing paper, the required pattern can be printed out. Its principle is similar to that of a thermal fax machine. The image is generated by heating and chemical reactions in the film. This thermal printer chemical reaction is carried out at a certain temperature. High temperature will accelerate this chemical reaction. When the temperature is below 60°C, it takes a long time, even several years, for the paper to turn dark; when the temperature is 200°C, this reaction will be completed in a few microseconds.

[0003] "Vacuum pick-up suction head" is related to the application of thermal printers in some automated production lines and packaging equipment. "Vacuum pick-up suction head" refers to the use of vacuum suction to pick up, move or position materials (such as label paper, printing media, etc.) needed by thermal printers during automated production processes; "Vacuum pick-up suction head" is to absorb objects by generating negative pressure, thereby achieving automatic material pick-up and placement. It is usually composed of a vacuum suction cup and a vacuum pump. The suction cup can tightly absorb the surface of the object and move the object to a specified position. This process does not require direct contact with the object, reducing damage to the surface of the material, and is suitable for some relatively fragile, delicate or irregularly surfaced objects; in some automated label printing systems or packaging production lines, vacuum pick-up suction heads can be used to automatically load paper or label paper for thermal printers. Through the vacuum suction head, the machine can accurately extract label paper from the material box and feed it into the printer for printing. Especially in high-speed and high-precision production lines, vacuum suction heads can improve production efficiency, reduce manual intervention, and ensure accurate alignment of labels or paper; Existing technology: For workpieces with a length-to-thickness ratio greater than 100 mm and a thickness of 2 mm or less, aluminum alloy (Al6061 or Al7075) or carbon steel is often used for processing.

[0004] Disadvantages: Workpieces with a length-to-thickness ratio greater than 100 and a thickness of 2 mm or less, when processed with aluminum alloy or carbon steel, will be severely warped after forming. The flatness is generally greater than 0.5 mm, and some warping is even greater than 10 mm. The one-time forming rate is extremely low. In most cases, it needs to be calibrated several times before it can be barely used, and the flatness of the suction head is difficult to reach within 0.10 mm. (The flatness of the existing suction head is greater than 0.5, which is prone to serious vacuum leakage and material drop during vacuum adsorption). In view of this, we propose a thin-sheet vacuum material suction head made of ceramic material. Summary of the invention

[0005] The purpose of the present invention is to provide a thin-sheet vacuum material removal suction head made of ceramic material to solve the problems raised in the above background technology.

[0006] In view of this, the present invention provides a thin-sheet vacuum material pickup suction head made of ceramic material, comprising: The thin sheet is in an "I"-shaped structure, the thin sheet is symmetrically provided with vacuum air grooves, the bottom of the vacuum air grooves is provided with a plurality of air holes 1, and a suction cup is fixedly installed at the bottom end of the air holes 1; A circular tube is arranged above the thin sheet, and a connecting tube is fixedly installed at the bottom end of the circular tube, and U-shaped tubes fixed to the thin sheet are fixedly installed at both ends of the connecting tube, and an air hole two connected to the two ends of the U-shaped tube is opened on the top of the thin sheet, and a connecting groove connected to the vacuum air groove is opened on the surrounding side of the air hole two.

[0007] In the present technical solution, by setting up a round tube, a connecting tube and a U-shaped tube, the top end of the round tube can be fixed to one end of the vacuum pump through a thread. When the vacuum pump starts running, one end of the vacuum pump will absorb the air in the vacuum air groove through the round tube, the connecting tube, the U-shaped tube, the air hole 2 and the connecting groove, and the vacuum air groove absorbs the gas in the suction cup through a plurality of air holes 1, and the suction cup is pressed against the workpiece to ensure that negative pressure is formed inside the suction cup to fix the workpiece.

[0008] In the above technical solution, further, it also includes: Two grooves are symmetrically arranged at the bottom of the sheet, and a micro electric push rod 1 is fixedly installed on the inner wall of the groove, a fixing plate is fixedly installed on the output shaft of the micro electric push rod 1, a connecting block is symmetrically fixedly installed on the bottom of the fixing plate, a micro electric push rod 2 is fixedly installed on the bottom end of the connecting block, a fixing strip is fixedly installed on the output shaft of the micro electric push rod 2, and a plurality of brushes are provided at the bottom of the fixing strip.

[0009] In the present technical solution, when there is a large amount of dust on the workpiece, the micro electric push rod 1 can be started, and the output shaft of the micro electric push rod 1 can drive the fixed plate to move downward. At the same time, the fixed plate drives the micro electric push rod 2, the fixed bar and a number of brushes to move downward through the connecting block until the micro electric push rod 2 is located under the number of suction cups. Then, the micro electric push rod 2 is started, and the output shaft of the micro electric push rod 2 drives the fixed bar to move back and forth, and the fixed bar drives the number of brushes to move back and forth to clean the dust on the workpiece, ensuring that the suction cup can tightly adsorb the workpiece.

[0010] In the above technical solution, further, the thin sheet is made of ceramic material, and the circular tube, connecting tube and U-shaped tube are connected.

[0011] In this technical solution, the ceramic material has high stability and high strength, and can be formed in one time, replacing the existing process of difficult-to-process parts with a length-to-thickness ratio greater than 100mm and a thickness less than or equal to 2mm. It replaces the yield and warping of the original metal parts and improves the utilization rate of the thin sheets. The processing material and process are changed, and aluminum-based ceramic powder is die-cast and sintered in one time. Because the hardness and strength of ceramics are much greater than those of ordinary metals, they have uniform internal stress and strong resistance to deformation after sintering, so they have inherent process advantages for long and thin workpieces. When the vacuum pump is started, one end of the vacuum pump will absorb the gas in the round tube, connecting tube and U-shaped tube.

[0012] In the above technical solution, further, the circular tube, the connecting tube and the U-shaped tube are an integrally formed structure, and both ends of the U-shaped tube are tightly bonded to the thin sheet.

[0013] In this technical solution, the structural stability of the circular tube, the connecting tube and the U-shaped tube is ensured, and the structural stability of the two ends of the U-shaped tube and the thin sheet is ensured.

[0014] In the above technical solution, further, it also includes: Two slots, the two slots are respectively opened on the two fixed strips, the ends of the two output shafts of the two micro electric push rods are fixedly installed with plug blocks, both sides of the plug blocks are opened with sockets, and the two plug blocks are respectively located in the two slots, the plug blocks are plugged into the slots, both sides of the slots and located in the fixed strips are opened with slide grooves, the slide grooves are connected with the sockets, a slide column is slidably installed in the slide groove, and one end of the slide column extends into the socket, one end of the slide column is fixedly installed with a spring fixed to the inner wall of the slide groove, a limiting groove is opened at the top of the slide groove, and a limiting rod fixed to the slide column is slidably installed in the limiting groove.

[0015] In the present technical scheme, when several brushes need to be replaced, the personnel manually squeezes the two limit rods in the corresponding limit grooves away from each other in the direction of the slot and squeezes the corresponding spring to contract, then the limit rod drives the slide column to slide in the slide groove until one end of the slide column is completely moved out of the slot, then the personnel removes the fixing strip from the plug block and aligns the slot in the new fixing strip with the slot; at this time, the personnel manually squeezes the two limit rods on the new fixing strip away from each other in the corresponding limit grooves and squeezes the corresponding spring to contract, the limit rod drives the slide column to slide in the slide groove, then the plug block is inserted into the slot, at this time, the two limit rods are released by hand, the spring rebounds and stretches to squeeze the slide column to move toward the plug block, until one end of the slide column is inserted into the slot, the new fixing strip is fixed on the micro electric push rod 2, and the brush is replaced.

[0016] In the above technical solution, further, the U-shaped tube is communicated with the second air hole.

[0017] In this technical solution, it is ensured that the U-shaped tube can absorb the gas in the second air hole.

[0018] In the above technical solution, further, the second air hole is connected to the connecting groove and the vacuum air groove.

[0019] In this technical solution, it is ensured that the second air hole is unobstructedly connected with the connecting groove and the channel in the vacuum air groove.

[0020] In the above technical solution, further, the widths of the four ends of the thin sheet are all 2 mm, and the width of the thin sheet is 118 mm.

[0021] In this technical solution, the yield rate and warping defects of the thin slices are reduced.

[0022] In the above technical solution, further, the distance between the two ends of the sheet is 88 mm, and the length of the sheet is 210 mm.

[0023] In this technical solution, the deformation resistance of the sheet is improved.

[0024] In the above technical solution, further, the vacuum air groove has a U-shaped structure.

[0025] In this technical solution, the workpiece yield rate is improved and the workpiece processing accuracy is improved.

[0026] The beneficial effects of the present invention are: 1. The ceramic sheet vacuum pick-up suction head uses ceramic material for the thin sheet. The high stability, high strength and one-time formability of the ceramic material replace the existing process of similar difficult-to-process parts with a length-to-thickness ratio greater than 100mm and a thickness less than or equal to 2mm, and replaces the original metal addition to reduce yield and warpage.

[0027] 2. The ceramic sheet vacuum feeding suction head has changed the processing material and process. It adopts aluminum-based ceramic Al2O3 powder die-casting and sintering for one-time forming.
