Description

Technical Field

[0001] The invention belongs to the technical field of disc-shaped suspension porcelain insulator glue coating, and particularly relates to a disc-shaped suspension porcelain insulator blank glue coating device and glue coating method. Background Art

[0002] During the production process of disc-shaped suspension porcelain insulators, a layer of alumina powder needs to be placed inside the firing pad when the blank is fired. This is used to separate the bottom surface of the blank head from the firing pad and prevent the bottom surface of the blank head from sticking to the firing pad under the high temperature of the firing kiln. The more advanced practice in the industry is to apply a layer of special glue on the bottom surface of the blank head, which also serves to isolate the blank from the firing pad, and no longer uses the isolation function of alumina powder. The advantage of this is that it avoids the economic loss caused by the granular alumina powder being blown onto the surface of the blank with the stirring of the airflow in the kiln during the firing stage of the blank, resulting in waste.

[0003] At present, the glue coating on the head of the blank is done manually. During the sandblasting process of the blank, the operator holds the glue cup in one hand and uses a brush with glue on the other hand to apply special glue to the heads of the blanks on the conveyor belt of the sandblasting machine one by one. Obviously, the quality of this manual glue coating is difficult to control. In particular, the thickness, uniformity and glue coating position of the glue coating cannot be consistent for each product, and the coating effect is not ideal. It will also directly affect the effect of the special glue on the blank during firing to prevent adhesion and burning, and it is also easy to cause the head of the blank to stick to the burning pad. Waste. In order to improve the brushing quality, reduce economic losses, and save manpower, it is urgent to design an automatic glue coating device to replace manual glue coating. Summary of the invention

[0004] One object of the present invention is to provide a disc-shaped suspension porcelain insulator blank gluing device, and another object is to provide a gluing method using the same, which can facilitate gluing.

[0005] A disc-shaped suspended porcelain insulator blank glue coating device comprises an X servo axis, a Y servo axis, a Z1 axis cylinder, a Z2 axis cylinder and a glue liquid stirring barrel.

[0006] The movable end of the X servo axis has the fixed end of the Y servo axis.

[0007] The movable end of the Y servo axis has a fixed end of the Z1 axis cylinder and a fixed end of the Z2 axis cylinder.

[0008] A first residual liquid collection box is installed on one side of the fixed end of the Y servo axis.

[0009] The first residual liquid collecting box is provided with a residual liquid scraper moving shaft arranged in the X direction, and a residual liquid scraper is provided at the movable end of the residual liquid scraper moving shaft.

[0010] A second residual liquid collection box is installed on the other side of the fixed end of the Y servo axis.

[0011] A peristaltic pump is installed on the movable end of the Z1 cylinder shaft, and the outlet of the peristaltic pump is a dispensing hose.

[0012] The movable end of the Z2-axis cylinder is provided with a vertically arranged scraper rotating motor, and the scraper is fixed on the output shaft of the scraper rotating motor.

[0013] The outlet pipe of the glue mixing barrel is connected to the inlet of the peristaltic pump.

[0014] The glue liquid stirring barrel is provided with a stirrer and a liquid level sensor.

[0015] The top fixed end of the Y servo axis is provided with a distance measuring sensor.

[0016] The invention also provides a method for applying glue using the glue applying device for disc-shaped suspension porcelain insulator blank.

[0017] Its advantages are:

[0018] The device is designed with a peristaltic pump to control the amount of glue. When the dispensing tube moves at the head of the blank, the amount of glue squeezed out can be different according to the different diameters of the head of the blank. At the same time, the moving speed of the dispensing tube can be adjusted to meet the needs of glue coating thickness. The rotation speed of the scraper can be adjusted to meet the speed required by different concentrations of glue during the scraping process. The distance between the scraper and the head of the blank can be adjusted to meet the needs of different glue coating thicknesses.

[0019] In order to adapt to the possible height deviation of the same blank, the height of the blank head is measured by a distance sensor to control the actuator to accurately fall to a certain position above the blank. This design makes it possible to control the distance at which the scraper falls on the blank head during glue coating, and the thickness of the scraped glue is consistent. It also solves the problem of ensuring the same glue coating thickness when there is a height deviation of the same product.

[0020] The dispensing speed of the dispensing tube is adjustable to suit the glue coating thickness and the amount of glue required for different diameters. The rotation speed of the scraper is adjustable to suit the glue of different concentrations to be quickly flattened by the scraper.

[0021] There will be glue liquid at the glue dispensing tube outlet and the bottom edge of the scraper. For this reason, the glue dispensing tube outlet and the scraper will automatically return to the safe area after leaving the glue coating position. One is to prevent the residual liquid on the glue dispensing tube outlet and the glue coating scraper from dripping onto the blank umbrella plate, and the other is to scrape off the residual glue liquid on the scraper.

[0022] The glue mixing barrel for storing the glue coating liquid has a stirring function to prevent the concentration of the glue liquid from being weakened due to precipitation, and ensures the isolation of the special glue from the outside air, thereby stabilizing the production process and ensuring the consistency of the glue coating effect.

[0030] A disc-shaped suspended porcelain insulator blank gluing device can be used for gluing the blank head on a sandblasting machine, or an independent gluing machine to automatically brush a special glue on the blank head. The sandblasting machine conveyor belt 2 on the sandblasting machine conveys the blank 1 to the gluing station where the device is located, and the blank head is glued. The fixed bracket 16 is the frame beam of the sandblasting machine.

[0031] A disc-shaped suspended porcelain insulator blank glue coating device comprises an X servo axis 3, a Y servo axis 4, a Z1 axis cylinder 6, a Z2 axis cylinder 7 and a glue liquid stirring barrel 11. The Z1 axis cylinder 6 and the Z2 axis cylinder 7 are arranged along the Z1 axis and the Z2 axis respectively.

[0032] The fixed ends on both sides of the X servo axis 3 are mounted on the fixed bracket 16 , and the fixed end of the Y servo axis 4 is mounted on the movable end of the X servo axis 3 that moves along the X-axis direction.

[0033] The movable end of the Y servo axis 4 is mounted with the fixed end (Z1 axis cylinder rod) of the Z1 axis cylinder 6 and the fixed end (Z2 axis cylinder rod) of the Z2 axis cylinder 7 moving along the Y axis direction.

[0034] A first residual liquid collecting box (residual liquid collecting box A) 14 is installed on one side of the fixed end of the Y servo axis 4 .

[0035] The first residual liquid collecting box 14 is provided with two fixed ends of the residual liquid scraper moving shaft 8, and the movable end of the residual liquid scraper moving shaft 8 is provided with a residual liquid scraper 18 which is movable parallel to the X servo axis, and the residual liquid scraper 18 is U-shaped.

[0036] A second residual liquid collecting box (residual liquid collecting box B) 15 is installed on the other side of the fixed end of the Y servo axis 4 .

[0037] The movable end of the Z1-axis cylinder 6 (Z1-axis cylinder body) moves along the Z-axis direction, and a peristaltic pump 9 is installed on the movable end of the Z1-axis cylinder shaft 6 (the housing of the peristaltic pump 9 is fixed on the Z1-axis cylinder body), and the outlet of the peristaltic pump 9 is a dispensing tube 15. Driven by the Z1-axis cylinder 6, the peristaltic pump 9 and the dispensing tube 15 installed on the movable end of the Z1-axis cylinder shaft have two moving positions in the Z-axis direction, one position is above the second residual liquid collection box 17, that is, the outlet of the dispensing tube 15 on the Z1-axis cylinder 6 is above the second residual liquid collection box 17; the other position is that the outlet of the dispensing tube 15 moves to above the head of the blank 1.

[0038] The movable end (Z2 axis cylinder body) of the Z2 axis cylinder 7 moves along the Z axis direction, and a vertically arranged scraper rotating motor 5 is installed on the movable end of the Z2 axis cylinder 7 (the housing of the scraper rotating motor 5 is fixed on the Z2 axis cylinder body), and a scraper 13 is fixed on the output shaft of the scraper rotating motor 5. Driven by the scraper rotating motor 5, the scraper 13 rotates to complete the scraping operation of the glue on the head of the blank 1. The movable end of the Z2 axis cylinder 7 has two moving positions in the Z axis direction, one position is above the first residual liquid collection box 14, and the length direction of the scraper 13 is parallel to the X axis, and the first residual liquid collection box 14 is used to catch the residual liquid dripping from the scraper 13; the other position is that the scraper 13 moves to the top of the head of the blank 1, and the residual liquid scraper 18 is U-shaped and moves from the bottom of the scraper 13, which can clean the front, back and bottom of the lower edge of the scraper 13.

[0039] The Z1 axis cylinder 6 and the Z2 axis cylinder 7 are arranged in parallel and in opposite directions. Figure 5 shown.

[0040] The device is designed with a cleaning scraper mechanism (residual liquid scraper moving shaft 8 and residual liquid scraper 18). In order to prevent the glue from dripping onto the blank umbrella plate, residual liquid collection boxes are designed below the glue dispensing tube 15 and the scraper 13 respectively. After the glue dispensing tube 15 and the scraper 13 leave the working area, they can be moved to the top of the corresponding residual liquid collection box.

[0041] The outlet pipeline of the glue stirring barrel 11 is connected to the inlet of the peristaltic pump 9 .

[0042] The glue stirring barrel 11 is provided with a stirrer 19, for example, a stirring motor and stirring blades fixed on the output shaft.

[0043] A liquid level sensor 12 is arranged on the glue mixing barrel 11 . When the liquid level is lower than or higher than a warning value, an alarm is triggered to prompt the user to add glue or to stop adding glue into the glue mixing barrel 11 .

[0044] The liquid level sensor 12 is used to detect the height of the glue in the glue mixing barrel 11, and the stirring motor is used to stir the glue in the glue mixing barrel 11. On the one hand, the rotation speed of the peristaltic pump 9 can realize quantitative operation according to the amount of glue used for different products; on the other hand, the moving speed of the glue dispensing tube 15 controlled by the X servo axis 3 can also control the amount of glue on the head of the blank 1.

[0045] A distance sensor 10 is provided at the top fixed end of the Y servo axis 4, and the distance sensor 10 is used to locate the top surface position of the head of the blank 1, and control the height of the dispensing tube 15 and the scraper 1 from the top of the blank 1 to a suitable position.

[0046] The bottom surface of the scraper 13 has the same shape as the head of the blank 1 and is at a certain distance from it. The cavity 20 formed when the scraper 13 rotates is the shape and amount of the glue scraped out.

[0047] The device comprises an X-axis, a Y-axis, a Z1-axis, a Z2-axis and a residual liquid scraper moving axis 8, a three-dimensional five-axis mechanism.

[0048] Sports Overview:

[0049] 1.5-axis linkage:

[0050] 1) Control the length and density of the glue dispenser in the X-axis direction.

[0051] 2) The Y-axis direction of the gap between the scraper 13 and the head of the blank 1.

[0052] 3) Clean the residual liquid on the scraper 13 in the Z2 axis direction.

[0053] 4) Move the dispensing tube 15 in the Z1 axis direction of the dispensing position.

[0054] 5) Rotation of the scraper 13.

[0055] 2.8 main actions:

[0056] 1) X servo axis 3, controls the dispensing length and density.

[0057] 2) Y servo axis 4 controls the gap between the scraper 13 and the head of the blank 1 to suit different products and the same product due to manufacturing differences. It is necessary to control the positioning of the scraper 13 from the head of the blank 1 according to the height signal fed back by the distance sensor 10.

[0058] 3) The scraper rotating motor 5 servo axis controls the rotation angle and number of rotations of the scraper 13.

[0059] 4) Z1 cylinder shaft, used to push the peristaltic pump 9 and the glue dispensing tube 15 to the glue dispensing position or to a safe position away from the head of the blank 1.

[0060] 5) Z2 axis cylinder, used to push the scraper rotating motor 5 servo axis to the scraping position or to the residual liquid cleaning position.

[0061] 6) The residual liquid scraper 18 on the movable end of the moving shaft 8 is used to scrape off the residual liquid on the scraper 13 during the movement.

[0062] 7) The peristaltic pump 9 quantitatively delivers the glue solution.

[0063] 8) Stirring and liquid level alarm of glue mixing barrel 11.

[0064] The device can be installed at the upper end of the conveyor line of the existing sandblasting machine, and can also be separated to form a special glue coating machine. The device uses the inner eye glue spraying station of the sandblasting machine to perform the glue coating operation on the head. When the blank 1 is moved from the rear end of the head outer circle positioning mechanism of the sandblasting machine, that is, the blank 1 falls on the conveyor line of the sandblasting machine and is moved to the inner eye glue spraying station, the device completes the automatic glue coating function on the top surface of the head of the blank 1.

[0065] The blank 1 of the disc-shaped suspension porcelain insulator is close to the finished product after sandblasting, glazing, and gluing on the head. Therefore, the gluing device must have reliable positioning accuracy when implementing the gluing process on the blank head. The brushing and dispensing tube 15 for quantitative extrusion and the scraper 13 for leveling the glue liquid need to be precisely controlled when they come into contact with the blank 1. Under the mechanical and electrical control adopted by the gluing device, the distance sensor 10 first measures the height of the head of the blank 1, and according to the data stored in the PLC in advance, combined with different products, the controller sends a control instruction to the actuator, which can solve the height deviation of the same product in manufacturing, and can also ensure the thickness of the head glue, which can achieve better results than manual gluing.

[0066] The X servo axis 3, the Y servo axis 4 and the residual liquid scraper moving axis 8 are all existing mechanical structures, such as a guide rail slider pair or a lead screw nut pair.

[0067] A method for applying glue using a disc-shaped suspension porcelain insulator blank gluing device comprises the following steps:

[0068] The Z1-axis cylinder 6 and the Z2-axis cylinder 7 follow the movable end of the Y-servo axis 4 to move up and down, and the fixed end of the Y-servo axis 4 follows the movable end of the X-servo axis 3 to move left and right.

[0069] When the blank 1 moves to the station at the lower end of the glue dispensing tube 15, the distance sensor 10 first measures the height of the head of the blank 1, adapts to the height deviation of the blank 1, ensures that the gap between the scraper 13 and the top surface of the head of the blank 1 meets the thickness of the glue coating, controls the glue dispensing tube 15 to descend from the top, and moves the outlet of the glue dispensing tube 15 to a suitable position away from the top surface of the head of the blank 1. The glue is quantitatively injected under the control of the peristaltic pump 9, and the amount of glue used is set on the PLC touch screen according to the different areas of the head of the blank 1. The glue is squeezed and applied to the head of the blank 1. The outlet of the glue dispensing tube 15 is on the top surface of the head of the blank 1. The cylinder rod of the Z1-axis cylinder 6 extends outward, and glue is dispensed along the diameter direction. The glue droplets at the distance from the center are small, and the glue droplets close to the circumference are large. The length and density of the glue dispensing can be quantitatively adjusted under the control of the PLC.

[0070] After the scraper 13 squeezes out the glue from the glue dispensing tube 15, the cylinder rod of the Z2-axis cylinder 7 retracts and moves to a suitable position from the upper end of the head of the blank 1. The distance between the bottom surface of the scraper 13 and the head of the blank 1 is the required glue coating thickness. The scraper rotating motor 5 drives the scraper 13 to rotate 360° to scrape the glue on the head of the blank 1. The rotation speed and number of revolutions of the scraper 13 can be set.

[0071] After the glue dispensing tube 15 completes one dispensing, the cylinder rod of the Z1 axis cylinder 6 extends and moves to the second residual liquid collection box 17 .

[0072] After the scraper 13 completes a scraping process, the cylinder rod of the Z2-axis cylinder 7 extends and moves to the first residual liquid collection box 14. At the same time, the residual liquid scraper 18 moves along the residual liquid scraper moving axis 8 to clean the residual glue on the surface of the scraper 13 to prevent the glue from accumulating for a long time and affecting the gluing effect, and wait for the gluing of the next blank 1.

[0073] The glue mixing barrel 11 is equipped with a liquid level sensor 12 for detecting the height of the glue. When the height is lower than the lower limit, an alarm is sounded to prompt the glue to be replenished. A stirrer 19 is installed in the glue mixing barrel 11. The stirring motor rotates during the glue coating process to prevent the glue from being thinned due to the precipitation of the glue.

[0074] The glue liquid is stored in the glue liquid stirring barrel 11. During the glue coating operation, the glue liquid is stirred to prevent the glue liquid from settling.
