Description

Technical Field

[0001] The invention relates to the technical field of automatic gluing equipment for insulators, and in particular to an automatic gluing device and a gluing method for disc-shaped suspension insulators. Background Art

[0002] With the rapid development of my country's power grid, insulators, as important components of high-voltage transmission lines, are increasingly used in UHV transmission lines and various electrical equipment, playing the role of insulation, mechanical connection, and conductor support. With the development of technology, the design and manufacture of insulators are also constantly improving to meet the requirements of use under higher voltage levels and more complex environmental conditions. For example, insulators used in UHV transmission lines require higher mechanical strength and better anti-pollution performance.

[0003] The disc suspension insulator widely used in high-voltage power transmission and transformation is assembled by the insulator body (porcelain), steel legs and iron cap through high-strength cement bonding. The quality of the assembly of the insulator body, steel legs and iron cap is directly related to the performance of the insulator in the high-voltage power transmission and transformation network. The assembly quality requirements are high, such as the vertical centering of the insulator body, steel legs and iron cap, the coaxiality ≤0.5; no residual pores in the cement, etc.

[0004] Traditional disc suspension insulators are generally assembled by hand, because each step requires manual operation, and the production speed is limited by the worker's operating speed, and the efficiency is relatively low. In addition, manual assembly requires workers to personally perform operations such as glue injection and exhaust, which requires high skills of workers. Its quality is greatly affected by the skills and experience of the operators, so the product quality may fluctuate to a certain extent. At present, the manufacturing process of insulators is developing towards digitalization, intelligence and automation to improve production efficiency and product quality.

[0005] Chinese patent authorization announcement document number CN103345992 B discloses a step-by-step disc-shaped suspension insulator gluing method, which discloses an automatic gluing machine, including a work platform and five stations arranged on the work platform, namely station A, station B, station C, station D and station E, wherein station A is equipped with an insulator body positioning seat and a cement pouring machine for completing the process of manually placing the insulator body and pouring cement in the insulator body, station B is equipped with a steel foot clamp, an insulator body clamp and a first vibration device for completing the process of inserting the steel foot and vibration, station C is equipped with an iron cap seat, an iron cap clamp and a cement pouring machine for completing the process of manually placing the iron cap and pouring cement into the iron cap, station D is equipped with an iron cap positioning seat and a second vibration device for completing the process of positioning the iron cap, inserting the insulator body and vibration, and station E is equipped with a workpiece detection, cleaning and removal device for completing the cleaning, inspection and removal processes. The insulator positioning seat can reciprocate between station A and station B, and the iron cap positioning seat can reciprocate between station D and station E. The automatic glue assembly machine for disc-shaped suspension insulators of the above technical solution has stable and reliable product quality, high automation and production efficiency, and reduces the labor intensity of workers. However, it still has some problems. For example, the placement of the insulator body and the iron cap needs to be done manually, and the automation and production efficiency are still low, which needs to be further improved.

DETAILED DESCRIPTION

[0020] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the present invention.

[0021] An automatic gluing device for disc-shaped suspension insulators according to an embodiment of the present invention, see Figures 1 to 4 , including a main conveying line 10, a feeding mechanism 20, a first gluing mechanism 30, a porcelain piece 200 conveying line 40, a porcelain piece installation mechanism 50, a second gluing mechanism 60, a steel foot conveying line 70, a steel foot installation mechanism 80 and a swing mechanism 90.

[0022] The main conveying line 10 is along the horizontal direction. Figure 1 The conveyor line body extending in the left and right directions as shown, the left end is the front end or input end, and the right end is the rear end or output end. The main conveyor line 10 is along the conveying direction, that is, the direction from the input end to the output end, that is, Figure 1 From left to right as shown, there are iron cap gluing stations, porcelain installation stations, porcelain gluing stations, steel foot installation stations and swing stations. It should be noted that in order to achieve temporary stays at each station so as to complete the corresponding process, corresponding blockers (not shown) and check valves (not shown) are provided at each station. The specific structure of the blocker and the check valve is not specifically described or limited. For example, the blocker is an existing conventional blocking cylinder, and the check valve is an existing conventional pneumatic check valve. It can be used in conjunction with an existing conventional photoelectric sensor for in-place detection (not shown), that is, when the workpiece reaches a certain station on the main conveyor line 10, the photoelectric sensor detects the workpiece, and then the blocker and the check valve block the workpiece. In some preferred embodiments of the present invention, the main conveyor line 10 is an existing conventional double-speed chain conveyor line. The specific structure and working principle are not described in detail here, and those skilled in the art can easily know and implement it.

[0023] The feeding mechanism 20 is arranged at the front end of the main conveyor line 10, that is, the input end, and is used to transfer the iron caps 100 to be glued onto the main conveyor line 10 to realize automatic feeding of the iron caps 100. The feeding mechanism 20 in the embodiment of the present invention is an existing conventional lifting pallet transfer mechanism, which is used to vertically change the tooling pallet to realize the recycling of empty pallets. The specific structure is not described in detail, and it is easy for those skilled in the art to know and implement it.

[0024] The first gluing mechanism 30 is arranged on one side of the iron cap gluing station ( Figure 1 The rear side is exemplified in the figure), which is used to add high-strength cement into the iron cap 100 to be glued on the main conveyor line 10 according to the required set amount of cement. The high-strength cement is the high-strength cement commonly used in existing disc-shaped suspension insulators, and the details are not repeated here. The set amount of cement is also the amount used when gluing existing disc-shaped suspension insulators, and the details are not repeated here. In order to achieve the quantitative filling of high-strength cement into the iron cap 100 according to the set amount of cement, the first gluing mechanism 30 of the embodiment of the present invention is provided with a quantitative device (not shown), which is preferably a height detection sensor, which realizes the quantitative amount of cement by detecting the height of the cement filled into the iron cap 100, and is also equipped with an alarm (not shown). When the amount of cement added to the iron cap 100 reaches the set amount, the alarm will not generate an alarm signal, the blocker and the check valve will release the blockage of the iron cap 100, and the main conveyor line 10 will run the iron cap 100 filled with high-strength cement to the next station, that is, the porcelain installation station; if it is detected that the amount of cement added to the iron cap 100 does not reach the set amount, such as when the amount of cement in the first glue-binding mechanism 30 is insufficient, this will occur. At this time, the alarm will sound an alarm to prompt the operator to check the cause and solve it in time to avoid affecting normal production. In addition, preferably, the first glue-binding mechanism 30 includes a glue storage tank, and an activity maintenance mechanism (not shown) for ensuring the activity of the high-strength cement in the glue storage tank is also provided in the first glue-binding mechanism 30. For the activity maintenance mechanism, it can be selected as an existing conventional water cooler and atomizer for cement. The specific structure and working principle will not be described in detail, and those skilled in the art can easily know and implement it. The structure of the second glue-binding mechanism 60 is consistent with that of the first glue-binding mechanism 30, so it will not be described in detail here. The second gluing mechanism 60 is different from the first gluing mechanism 30 in that the installation position is different (the second gluing mechanism 60 is arranged on one side of the middle position of the main conveying line 10 (such as Figure 1 In the example, the second binding mechanism 60 is arranged behind the first binding mechanism 30. Figure 1 The second gluing mechanism 60 is used to add high-strength cement to the porcelain piece 200 which is spun and fixed in the iron cap 100 filled with high-strength cement.

[0025] The porcelain piece 200 conveying line 40 is arranged on one side of the main conveying line 10 ( Figure 1The porcelain piece 200 conveyor line 40 is used to convey the porcelain pieces 200 to be glued in the buffer. The steel foot conveyor line 70 is also arranged on one side of the main conveyor line 10 ( Figure 1 In the example shown as the rear right end), the steel foot conveyor line 70 is used to convey the cached steel foot 300 to be installed. That is, the porcelain piece 200 conveyor line 40 and the steel foot conveyor line 70 are arranged relatively spaced apart on the left and right, and the conveying directions of the porcelain piece 200 conveyor line 40 and the steel foot conveyor line 70 are opposite, and the direction of the porcelain piece 200 conveyor line 40 is consistent with the direction of the main conveyor line 10. Thereby, the porcelain piece installation mechanism 50 and the steel foot installation mechanism 80 can be arranged on one side of the middle position of the main conveyor line 10, which can reduce the entire device to be more compact and occupy a smaller area. In the embodiment of the present invention, the porcelain piece 200 conveyor line 40 and the steel foot conveyor line 70 are also existing conventional double-speed chain conveyor lines.

[0026] The porcelain installation mechanism 50 is arranged between the main conveyor line 10 and the porcelain 200 conveyor line 40, and is used to sequentially transfer and spin-fix the porcelain 200 cached on the porcelain 200 conveyor line 40 to the iron cap 100 filled with cement on the main conveyor line 10 that runs to the porcelain installation station. The steel foot installation mechanism 80 is arranged between the main conveyor line 10 and the steel foot conveyor line 70, and is used to sequentially transfer and spin-fix the steel foot 300 cached on the steel foot conveyor line 70 to the porcelain 200 filled with cement on the main conveyor line 10 that runs to the steel foot installation station. The swing mechanism 90 is arranged on one side of the swing station ( Figure 1 The rear side is shown as an example in the figure) and is used to continue spinning and fixing the porcelain part 200 in the disc-shaped suspension insulator that runs to the swinging station on the main conveyor line 10 in the iron cap 100 and to continue spinning and fixing the steel foot 300 in the porcelain part 200 while vibrating to eliminate bubbles in the cement in the porcelain part 200 and the iron cap 100.

[0027] For the porcelain installation mechanism 50, the steel foot installation mechanism 80 and the rocking mechanism 90, all of them are devices provided with a crank-connecting rod mechanism. Specifically, the porcelain installation mechanism 50 includes a first truss (not shown) that can move laterally and vertically, a first vertical telescopic rod connected to the first truss (not shown, its structure is consistent with the second vertical telescopic rod), a first crank-connecting rod mechanism (not shown, its structure is consistent with the second crank-connecting rod mechanism) connected to the driving end of the first driving mechanism (not shown, such as a driving motor) provided on the first vertical telescopic rod, and a first clamp 51 connected to the output end of the first crank-connecting rod mechanism. The first clamp 51 includes a plurality of first clamps 511 that expand outward to clamp the porcelain 200 and perform a spinning action under the drive of the first driving mechanism and contract inward to release the porcelain 200 after the spinning is completed. The first crank-connecting rod mechanism includes a first crankshaft (not shown) provided at the input end and the output end, respectively, and a first intermediate connecting rod (not shown) located between the two first crankshafts. As shown in FIG. Figure 2As shown, the steel foot installation mechanism 80 includes a second truss (not shown) that can move laterally and vertically, a second vertical telescopic rod 81 connected to the second truss, a second crank-connecting rod mechanism 83 connected to the driving end of a second driving mechanism 82 arranged on the second vertical telescopic rod 81, and a second clamp 84 connected to the output end of the second crank-connecting rod mechanism 83. The second clamp 84 includes a plurality of second clamps 841 that contract inwardly to clamp the steel foot 300 and perform a spinning action under the drive of the second driving mechanism 82 and expand outwardly to release the steel foot 300 after the spinning is completed. The second crank-connecting rod mechanism 83 includes a second crankshaft 831 respectively arranged at the input end and the output end and a second intermediate connecting rod 832 located between the two second crankshafts 831. The swing mechanism 90 includes a third truss (not shown) that can move horizontally and vertically, a third vertical telescopic rod (not shown) connected to the third truss, and its structure is consistent with the second vertical telescopic rod, a third crank-connecting rod mechanism (not shown) connected to the driving end of a third driving mechanism (not shown) provided on the third vertical telescopic rod (not shown), a third clamp (not shown, and its structure is consistent with the second clamp) connected to the output end of the third crank-connecting rod mechanism (not shown), and a vibrator (not shown) provided on the third clamp. The third clamp includes multiple A third clamp (not shown in the figure, its structure is consistent with that of the second clamp) contracts inward to clamp the steel foot 300 or the porcelain part 200 and performs spinning under the drive of the third driving mechanism and expands outward after the spinning is completed to release the steel foot 300 or the porcelain part 200. When the third clamp clamps the steel foot 300 or the porcelain part 200 for spinning, the vibrator vibrates to eliminate bubbles in the cement in the porcelain part 200 and the cement in the iron cap 100. The third crank-connecting rod mechanism includes a third crankshaft respectively provided at the input end and the output end and a third intermediate connecting rod located between the two third crankshafts. In other words, the main structures of the porcelain installation mechanism 50, the steel foot installation mechanism 80 and the rocking mechanism 90 are similar, and all include a truss, a telescopic rod, a crank-connecting rod mechanism, a driving mechanism and a clamp. In the embodiment of the present invention, the first truss, the second truss and the third truss are all double truss structures, as exemplified by Figure 1 The cross-shaped structure shown has a transverse guide rail (not shown) and a vertical guide rail (not shown) to enable transverse and vertical movement. The difference is that the fixture of the porcelain mounting mechanism 50 is different from the fixture of the steel foot mounting mechanism 80 and the swing mechanism 90, and the swing mechanism 90 is also provided with a vibrator in the fixture.

[0028] The structures of the first clamp of the porcelain installation mechanism 50 and the second clamp of the steel foot installation mechanism 80 are different. Specifically, Figure 3As shown, the structure of the steel foot installation mechanism 80 is used as an example to illustrate the embodiment of the present invention. The second clamp includes a second clamp body in the middle and a plurality of (four in the figure) second clamp jaws distributed around the periphery of the second clamp body. The lower end of any second clamp extends inwardly, that is, the lower ends of all second clamp jaws shrink inwardly. When clamping, they can be clamped on the outer wall of the steel foot 300 to achieve clamping so that they can reciprocate under the driving action of the second driving mechanism and the second crank connecting rod mechanism to achieve the spinning fixation of the steel foot 300. As for the clamp of the porcelain installation mechanism 50, that is, the first clamp, as shown in FIG. Figure 4 As shown, the first clamp includes a first clamp body in the middle and a plurality of (two in the figure) second clamps distributed around the periphery of the first clamp body, and any second clamp is L-shaped, that is, the lower end of the second clamp is extended outward, so that the second clamp can be pressed against the inner wall of the porcelain part 200 when expanding outward to realize the spinning installation of the porcelain part 200. The purpose of such design is to use the clamp of this structure. Since the middle part of the top of the porcelain part 200 has an inwardly concave cavity for the filling of high-strength cement and the installation of the steel foot 300, the first clamp is pressed against the inner wall of the porcelain part 200 during the spinning installation, so that the first clamp and the inner wall of the porcelain part 200 can form a sufficiently large friction force, which is convenient for the spinning installation of the porcelain part 200. As for the vibrator, it is a conventional high-frequency low-amplitude vibration device used for the glue assembly of disc-shaped suspension insulators.

[0029] In some preferred embodiments of the present invention, the ceramic installation mechanism 50, the second glue installation mechanism 60 and the steel foot installation mechanism 80 share a common installation base. The first truss of the ceramic installation mechanism 50 and the second truss of the steel foot installation mechanism 80 share a common vertical truss. This can improve the integration, reduce the occupied area, and make the entire device more compact.

[0030] The embodiment of the present invention also provides a gluing method of the automatic gluing device for the disc-shaped suspension insulator based on the above embodiment, such as Figure 5 As shown, the following steps are included: The loading mechanism 20 is lifted to transport the tray with the iron caps 100 to be glued to the front end of the main conveyor line 10; The main conveyor line 10 is operated to transfer the tray with the iron caps 100 to be glued to the iron cap glueing station and is blocked by the blocker and the backstop at the iron cap glueing station; The first gluing mechanism 30 fills the iron cap 100 to be glued with high-strength cement according to the set amount and stops filling after the detection reaches the set amount. The main conveyor line 10 runs forward to sequentially transfer the iron caps 100 to be glued at the rear end to the iron cap gluing station for filling with high-strength cement. If the detection does not reach the set amount, the alarm will sound an alarm prompt; As the main conveyor line 10 continues to run, the iron cap 100 filled with high-strength cement runs to the porcelain installation station, and the porcelain installation mechanism 50 transplants the porcelain 200 cached on the porcelain 200 conveyor line 40 and spins and fixes it on the iron cap 100 filled with high-strength cement running to the porcelain installation station; The iron cap 100 with the porcelain part 200 installed moves forward to the porcelain part gluing station along with the operation of the main conveyor line 10. The second gluing mechanism 60 adds high-strength cement to the porcelain part 200 according to the set amount and stops adding after the detection reaches the set amount. The main conveyor line 10 moves forward to sequentially transfer the porcelain part 200 filled with cement at the rear end of the operation to the steel foot installation station for installation of the steel foot 300. If the detection does not reach the set amount, the alarm will sound an alarm prompt; The steel foot installation mechanism 80 transfers and spins the steel foot 300 cached on the steel foot conveyor line 70 to the porcelain piece 200 filled with high-strength cement running to the steel foot installation station on the main conveyor line 10; The porcelain pieces 200 with the steel legs 300 installed thereon move forward to the swinging station in sequence as the main conveying line 10 runs, and the swinging mechanism 90 continues to spin the steel legs 300 and the porcelain pieces 200 and vibrates at the same time to eliminate bubbles in the high-strength cement; The glued disc-shaped suspension insulator is moved forward to the next process as the main transmission line 10 runs.

[0031] In summary, the automatic gluing device for disc-shaped suspension insulators in the embodiment of the present invention realizes automatic loading and automatic installation of iron caps, porcelain parts and steel feet, and automatic filling of cement, with a high degree of automation, and realizes automatic gluing in the production process of disc-shaped suspension porcelain insulators, thereby improving the production efficiency of porcelain insulators, reducing the labor intensity of workers, and being able to complete more insulator gluing tasks in a short time; it reduces the links of manual operation and reduces product quality problems caused by improper manual operation.
