Description

Technical Field

[0001] The invention relates to the technical field of glass insulator production, and in particular to glass insulator assembly equipment. Background Art

[0002] As a key component in the power transmission system, glass insulators are widely used for insulation and mechanical support of overhead transmission lines. Their core function is to form an insulator string through series assembly to withstand high voltage and mechanical loads. The assembly process of traditional glass insulators mainly relies on manual operation. Workers need to connect individual insulators one by one through the insulator's hanging ears and metal heads, and manually insert connecting fixtures such as pins or springs to complete the fixation. This operation method has low assembly efficiency, unstable assembly quality, and high labor intensity. Especially in the large-scale construction of high-voltage transmission lines, the low assembly efficiency of insulator strings affects the supply of components and has become an important bottleneck restricting the progress of the project.

[0003] With the growing demand for efficient production in the power industry, a number of semi-automatic equipment for insulator assembly have emerged in recent years. However, the positioning accuracy of insulator hanging is poor and the hanging stability is low. The main problems of assembly accuracy and reliability have not been completely solved. In addition, the equipment maintenance cost is high, making it difficult to popularize in power construction projects that move with the construction site.

[0004] Although some automated insulator assembly equipment optimizes the insulator's suspension structure and maintains stable suspension of the insulator, it does not fully consider the compensation for alignment deviations during the insertion of connecting fixtures such as pins or spring clips, which can easily cause the connecting fixtures to wear out or become loosely fixed.

[0005] Currently, the prior art includes:

[0006] (1) Assembly efficiency and cost issues: Existing automated equipment relies on complex mechanical structures or high-precision sensors (or high-value equipment such as robotic arms), which results in excessively high equipment purchase and maintenance costs, making it difficult to achieve economical production in the assembly steps of glass insulators.

[0007] (2) There are technical shortcomings in reliability: the latch fixing link lacks an effective adaptive compensation mechanism, which can easily lead to the risk of connection failure due to assembly deviation, or failures frequently occur during the assembly process (poor positioning accuracy makes it difficult to install smoothly), resulting in reduced equipment efficiency.

[0008] (3) Insufficient product adaptability: Because most automated assembly equipment relies on compatibility with multiple product assemblies to achieve flexible production, its assembly costs can be reduced; however, existing equipment is mostly designed for insulators of specific specifications, making it difficult to be compatible with the assembly requirements of insulator strings of different sizes or structures, and cannot achieve flexible assembly.

[0009] In summary, it is found that the prior art has at least the following technical problems:

[0010] Existing glass insulator assembly equipment has technical problems such as low assembly efficiency and equipment cost performance, poor positioning accuracy in connector assembly, low assembly stability, and inability to achieve flexible assembly and poor product adaptability.

Compared with traditional manual assembly, the glass insulator assembly equipment can efficiently and stably assemble large quantities of insulators into insulator strings, thereby improving the work efficiency of the assembly production line.

[0026] (2) Reducing the equipment cost and maintenance difficulty of traditional assembly production lines: The present invention optimizes the structure of the assembly equipment and improves the functional integration by decomposing and integrating the insulator string assembly process.

[0027] Among them, the conveyor belt is responsible for the transportation of insulators, and the transported insulators are transported in a vertical placement with the metal head on the top and the hanging ear on the bottom, so that the docking station can easily realize the clamping action when receiving the insulator; and the hanging station is responsible for mounting the insulator string, and after each additional insulator is mounted under the insulator string, the hanging station will drive the insulators in the string to rise one insulator position, so that the end hanging ear of the insulator string can be kept at the same height as the metal head interface of the next insulator to be hung through lifting, which is convenient for the docking and combination of the metal head interface and the hanging ear; through the beat control, the output of the conveyor belt, the transportation of the docking station and the hanging action of the hanging station are in the beat of the same cycle.

[0031] (3) Improving assembly accuracy and stability: Through the lifting and adjusting of the hanging platform, the precise rotation and horizontal sliding of the docking platform, the present invention can effectively ensure the docking accuracy of the insulator hanging ear and the metal head interface; through the horizontal force of the top block of the assembly table when delivering the plug-in, the shaking of the metal head of the insulator when inserting the connector is avoided; the plug-in unit of the plug-in hand has two degrees of freedom of movement in two directions, making the insertion of the connector more stable, and can effectively ensure the docking accuracy when the connector is inserted into the metal head interface of the insulator, reduce assembly deviation, improve the accuracy and stability of the assembly process, and thus reduce the risk of loose fixation or wear of the connector.

[0032] (4) Enhanced flexible assembly capability: The glass insulator assembly equipment of the present invention is compatible with glass insulators of various sizes and the same key structures to meet the assembly requirements of different products. It can flexibly adjust the conveyor belt, docking table, hanging table, assembly table, plug-in hand and vibration conveying unit, and has strong adaptability to support diversified production needs, thus avoiding the problem of poor assembly adaptability of traditional equipment when the specifications of the target assembly products change.

[0033] (5) Automated and intelligent production: The combination of the vibration conveying unit and the feeding unit enables the connectors to be automatically arranged and transported to the plug-in operator. The assembly process of the connectors is further separated by the assembly table, the plug-in operator and the vibration conveying unit, and the process of feeding and calling the connectors for assembly with the insulators on the assembly table is separated. The connectors can be fed continuously, and the plug-in operator does not need to wait for the connectors to be called, which further improves the efficiency of the process of assembling connectors and insulators. It also further improves the automation level of the glass insulator assembly equipment, reduces human intervention, and improves the production efficiency and assembly quality stability of the entire insulator assembly process.

[0034] In summary, the glass insulator assembly equipment of the present invention not only has significant improvements in assembly efficiency, cost control, assembly accuracy, equipment stability and product assembly quality stability, but also has strong flexible production capabilities, can adapt to changing market demands, and provides the function of assembling glass insulators of various sizes and specifications into strings on the same equipment platform, providing a practical solution for the efficient assembly and production of insulator strings.

[0054] The assembly table 4 has the freedom of horizontal rotation; a second indexing turntable 43 is installed under the assembly table 4 , and the turntable of the second indexing turntable 43 is connected to the bottom plate of the assembly table 4 .

[0055] During application, the second indexing turntable 43 is used to rotate the assembly table 4 so that the metal head interface 01 of the mounted insulator 00 string is aligned with the connector extending from the plug-in unit 61 .

[0056] The glass insulator assembly equipment of the present invention aims to solve the problems of low assembly efficiency, high equipment cost, poor positioning accuracy, poor assembly stability and insufficient product adaptability in the existing glass insulator 00 assembly technology, and the inability to realize flexible assembly; and the glass insulator assembly equipment of the present invention can:

[0057] (1) Improving the assembly efficiency of insulators 00: The present invention realizes the automated and continuous transportation and assembly of insulators 00 through the coordinated work of the conveyor belt 1 and the docking station 3, the hanging station 2, and the assembly station 4, thereby significantly improving the efficiency of the assembly process; compared with traditional manual assembly, the glass insulator assembly equipment can efficiently and stably assemble large quantities of insulators 00 into insulator strings 00, thereby improving the work efficiency of the assembly production line.

[0058] (2) Reducing the equipment cost and maintenance difficulty of the traditional assembly production line: The present invention optimizes the structure of the assembly equipment and improves the functional integration by decomposing and integrating the assembly process of the insulator 00 string. The conveyor belt 1 is responsible for conveying the insulator 00, and the conveyed insulator 00 is conveyed in a vertical position with the metal head on the top and the hanging ear 02 on the bottom, so that the docking station 3 can conveniently clamp the insulator 00 when receiving it. The hanging station 2 is responsible for mounting the insulator 00 string, and after each additional insulator 00 is mounted under the insulator 00 string, the hanging station 2 will drive the insulator 00 in the string to rise by one insulator 00 position, so that the end hanging ear 02 of the insulator 00 string can be kept at the same height as the metal head interface 01 of the next insulator 00 to be hung through lifting, so as to facilitate the docking and combination of the metal head interface 01 and the hanging ear 02. The output of the conveyor belt 1, the transportation of the docking station 3 and the hanging action of the hanging station 2 are in the same cycle rhythm through rhythm control.

[0059] The assembly table 4 is responsible for mounting the insulator 00 string and providing the metal head of each insulator 00 with a function of offsetting the horizontal force of the connector inserted into the metal head interface 01; the vibration conveying unit 5 and the insertion hand 6 respectively realize the automatic sorting and conveying of the connector and the insertion of the connector into the metal head interface 01 of the insulator 00; after the hanging table 2 is fully hung to form the insulator 00 string, it is swung and hung to the hook 42 of the assembly table 4, and the assembly table 4, the vibration conveying unit 5 and the insertion hand 6 are responsible for completing the assembly process of the connector between the insulators 00.

[0060] Thereby, the insulator 00 mounting and connector fixing processes of the traditional assembly process are split, so that the mounting process performed by the mounting station 2 and the connector fixing process performed by the assembly station 4 can be executed in parallel, so that the assembly efficiency of the overall process is higher, and the two processes of insulator 00 mounting and connector assembly are separated, so that the execution accuracy of the individual processes is also higher, and the overall failure rate of the glass insulator assembly equipment is further reduced, thereby improving the reliability of the glass insulator assembly equipment and reducing the frequency of maintenance.

[0062] (3) Improving assembly accuracy and stability: Through the lifting and adjusting of the hanging platform 2, the precise rotation and horizontal sliding of the docking platform 3, the present invention can effectively ensure the docking accuracy of the insulator 00 hanging ear 02 and the metal head interface 01; through the horizontal force of the top block 41 of the assembly platform 4 when delivering the plug-in, the shaking of the metal head of the insulator 00 when inserting the connector is avoided, and the plug-in unit 61 of the plug-in hand 6 has two-way freedom of movement, which makes the insertion of the connector more stable, and can effectively ensure the docking accuracy when the connector is inserted into the metal head interface 01 of the insulator 00, reduce assembly deviation, improve the accuracy and stability of the assembly process, and thus reduce the risk of the connector being loosely fixed or worn.

[0063] (4) Enhanced flexible assembly capability: The glass insulator assembly equipment of the present invention is compatible with glass insulators 00 of various sizes and the same key structures to meet the assembly requirements of different products.

[0064] (5) Automated and intelligent production: The combination of the vibration conveying unit 5 and the feeding unit 7 enables the connectors to be automatically arranged and transported to the plug-in hand 6. The assembly table 4, the plug-in hand 6 and the vibration conveying unit 5 further split the connector assembly process, separating the feeding and calling of connectors and the insulator 00 on the assembly table 4. The connectors can be fed continuously, and the plug-in hand 6 does not need to wait for the connectors to be called, which further improves the efficiency of the process of assembling connectors and insulators 00. It also further improves the automation level of the glass insulator assembly equipment, reduces human intervention, and improves the production efficiency and assembly quality stability of the entire assembly process of insulators 00.

[0068] When in use, the first visual camera is used to dynamically capture the orientation angle of the metal head interface 01 of the insulator 00 located at the conveyor belt 1, the docking station 3 and the hanging station 2, and transmit the captured position data to the device controller, and the device controller controls the docking station 3 to rotate the insulator 00 so that the metal head interface 01 of the insulator 00 clamped by the docking station 3 is aligned with the hanging ear 02 of the insulator 00 mounted on the hanging station 2; that is, the first visual camera provides the orientation angle of the metal head interface 01 of the insulator 00 located at the conveyor belt 1, the docking station 3 and the hanging station 2, so that after the docking station 3 receives the insulator 00 from the conveyor belt 1, it slides horizontally to move the metal head interface 01 to the hanging ear 02 of the insulator 00. During the movement of docking between the insulator 00 and the hanging ear 02, the metal head interface 01 of the insulator 00 is rotated to adjust toward the hanging ear 02. After the docking station 3 completes the horizontal sliding to dock the metal head interface 01 with the hanging ear 02, the first visual camera provides the final assembly confirmation data to confirm that the insulator 00 on the docking station 3 has completed the hanging action with the insulator 00 on the hanging station 2, and the hanging station 2 raises the mounted insulator 00 string and continues to enter the next insulator 00 mounting cycle; thereby ensuring the accurate implementation of the assembly process, and improving the reliability of the insulator 00 mounting process of the conveyor belt 1, the docking station 3 and the hanging station 2, and reducing the occurrence of faults.

[0069] Regarding the specific structure of the docking station 3, this embodiment Figures 1 to 4As shown, the docking platform 3 includes a base 31, a sliding rod 32, a docking slide 33, a telescopic cylinder 34 and a buffer unit 35; the two ends of the two sliding rods 32 are respectively connected to the fixed plates 311 at the two ends of the base 31 in the length direction, and are respectively distributed on both sides of the length direction of the fixed plate 311; the docking slide 33 is slidably connected to the two sliding rods 32; the telescopic cylinder 34 is arranged on the side close to the hanging platform 2, and the telescopic end of the telescopic cylinder 34 passes through the fixed plate 311 and is connected to the docking slide 33, and pushes, Pull the docking slide 33 to move back and forth between the conveyor belt 1 and the hanging platform 2; four buffer units 35 are provided, and a buffer unit 35 is installed on both sides of the length direction of the two fixed plates 311 respectively, and the buffer heads of the four buffer units 35 are all facing the side end surface of the docking slide 33; a first dividing turntable 36 is installed on the docking slide 33, and a self-centering three-claw clamp 37 is installed on the turntable of the first dividing turntable 36, and the three-claw clamp 37 is used to carry and clamp the hanging ear 02 of the insulator 00.

[0070] Regarding the positions of the buffer units 35 , the two buffer units 35 on the single fixed plate 311 are both surrounded by the two sliding rods 32 and are respectively close to the two sliding rods 32 .

[0071] When in use, the buffer unit 35 is used to slow down the moving speed of the end of the moving path of the docking slide 33, so that the docking slide 33 can move more smoothly when receiving and mounting the insulator 00 and the mounting accuracy is higher.

[0072] The three-jaw clamp 37 moves to the hollow part under the conveyor belt 1, and takes a picture through the first visual camera, and transmits data to confirm that the ear 02 of the insulator 00 is located within the encirclement of the three claws, and then drives the three-jaw clamp 37 to clamp. The three claws of the three-jaw clamp 37 push the ear 02 of the insulator 00 to automatically be in the center of the closed position of the three-jaw clamp 37, completing the self-centering clamping of the docking station 3.

[0073] Regarding the specific structure of the above-mentioned mounting platform 2, this embodiment Figure 1 and Figure 3As shown, the mounting platform 2 includes a base 21, a first linear module 22, a first cantilever 23, a rotary cylinder 24, a balancing cantilever 25, a slide cylinder 26, a first connecting plate 27 and a two-claw clamp 28; the first linear module 22 is vertically mounted on the base 21, the vertical side of the first cantilever 23 is connected to the slide of the first linear module 22, the rotary cylinder 24 is mounted on the horizontal side of the first cantilever 23, and the rotary head of the rotary cylinder 24 is connected to the front of the balancing cantilever 25; the back end of the balancing cantilever 25 is connected to the slide cylinder 26 The first connecting plate 27 is connected to the slide of the slide cylinder 26 on the horizontal side, and the first connecting plate 27 is connected to the two-claw clamp 28 on the vertical side; the two-claw clamp 28 is used to clamp the hanging ring 03 of the first insulator 00 of the insulator 00 string; when the rotary cylinder 24 rotates, the slide of the slide cylinder 26 extends out, so that the path of the swinging and hanging action of the insulator 00 string forms an arc, which is used to rotate the insulator 00 string from toward the docking station 3 to toward the assembly station 4 and hang it on the hook 42.

[0074] When in use, on the two-claw clamp 28 of the mounting table, the hanging ring 03 of the first insulator 00 drives the balancing cantilever 25 with the rotary cylinder 24, so that the string of insulators 00 mounted in a string is swung and rotated 180 degrees to be hung on the hook 42 of the assembly table 4, and the swinging and hanging action path of the insulator 00 string is an arc path, which can make the insulator 00 string smoothly hung on the hook 42 of the assembly table 4.

[0075] In addition, a counterweight 251 is provided on the balancing cantilever 25, and the counterweight 251 balances the weight of the insulator 00 string, the sliding cylinder 26, the first connecting plate 27 and the two-claw clamp 28, so as to avoid the problem of unbalanced shaking when the insulator 00 string is swung and hung; the balancing effect of the counterweight 251 enables the insulator 00 string to swing smoothly and be hung on the assembly table 4 during the process of the rotary cylinder 24 driving the balancing cantilever 25 to hang the insulator 00 string, thereby improving the success rate of the insulator 00 string being hung from the hanging table 2 to the assembly table 4, and further improving the reliability of the equipment.

[0076] In order to synchronize the rhythm of the conveyor belt 1 outputting the insulator 00 and the docking station 3 for the round trip transport, this embodiment Figure 1 and Figure 2 As shown, a plurality of blocking cylinders 11 are arranged on the hollow path of the conveyor belt 1 .

[0077] During use, the blocking arm of the blocking cylinder 11 swings up and down to abut against or separate from the hanging ear 02 of the insulator 00, so as to match the conveying rhythm of the insulator 00 with the transport rhythm of the docking station 3.

[0078] In order to enable the plug-in unit 61 to accurately insert the connector into the metal head interface 01 of the insulator 00, a second visual camera is also included on the plug-in unit 61. The shooting direction of the second visual camera is toward the assembly table 4, and the shooting center is colinear with the midline position of the top block 41 of the assembly table 4.

[0079] When in use, the second visual camera is used to dynamically capture the horizontal orientation angle and vertical height of the metal head interface 01 of the insulator 00 located on the assembly table 4, and transmit the captured position data to the equipment controller.

[0080] In order to ensure that the plug-in unit 61 can accurately insert the connector into the metal head interface 01 of the insulator 00 without causing the problem of assembly displacement due to misalignment, the embodiment Figure 1 As shown, a V-shaped opening is provided at the end of the top block 41. When the metal head of the insulator 00 abuts against the top block 41, the two side walls of the V-shaped opening abut against the outer periphery of the metal head of the insulator 00 in a self-centering manner, so as to self-position the centerline position of the insulator 00.

[0081] When in use, the centerline position of the metal head interface 01 of the insulator 00 is made to coincide with the centerline position of the V-shaped opening. When inserting the connector, the center of application of the horizontal force coincides with the centerline position of the metal head interface 01 of the insulator 00 and the centerline position of the V-shaped opening, so that the action of the plug-in unit 61 inserting the connector into the metal head interface 01 of the insulator 00 can be carried out smoothly without problems of force offset and assembly displacement due to insertion deviation.

[0083] During application, the spiral rising process of the vibration disk 51 is realized by the vibrator 52 and the spiral regular track. The spiral regular track not only guides the connecting parts to spirally rise, but also regularizes the orientation and arrangement of the connecting parts.

[0084] When the vibration conveying unit 5 needs to be adapted to other connecting parts, it only needs to replace the spiral regular track of the adapted vibration plate 51 and the linear guide groove 53 of the linear conveying connecting part, so as to realize the flexible adaptation of the vibration conveying unit 5 to connecting parts of various specifications.

[0089] Specifically, the connecting piece is a pin.

[0090] A second embodiment of the glass insulator assembly apparatus is as follows Figure 5As shown, the difference between this embodiment and the first embodiment is that the plug-in unit 61 includes a plug-in gun 611, and the tail of the plug-in gun 611 is connected to the output port of the delivery tube 71; a pneumatic auxiliary tube 614 is connected to the path of conveying the connector inside the plug-in gun 611, and the pneumatic auxiliary tube 614 is connected to the pressurized air source, and the connector is driven to move forward in the plug-in gun 611 by the pressurized compressed air; a clamping electric cylinder 612 and a clamping sensor 613 are installed on the muzzle adjacent to the plug-in gun 611, and the clamping sensor 613 identifies the position of the connector by infrared sensing.
