Description

Technical Field

[0001] This invention relates to the field of impregnation equipment technology, and more particularly to an impregnation equipment for glass insulator adhesive. Background Technology

[0002] In the production and post-processing of glass insulators, adhesive impregnation is a crucial step, aiming to ensure a strong, sealed, and durable bond between the metal fittings and the glass body. To achieve efficient and uniform adhesive coating, the glass insulators typically require multi-degree-of-freedom movements such as flipping, rotating, or tilting to ensure the adhesive fully covers and penetrates the desired area. Therefore, the industry widely employs automated equipment, with robotic grippers serving as the core actuators, responsible for the stable grasping and attitude control of the glass insulators.

[0003] In existing technologies, a common clamping method involves pre-forming one or more notches on the side wall of the cylinder at the end of the glass insulator. A robotic arm's clamping plate extends horizontally into the cylinder through these notches. Subsequently, the clamping plate is stretched axially, causing its outer edge to abut against the inner wall of the constricted structure within the cylinder, thereby clamping and fixing the glass insulator. While this method can meet clamping requirements to a certain extent, it reveals several significant drawbacks in practical applications: First, because the clamping plate needs to enter the cylinder through the side wall notch, its outer diameter must be smaller than the minimum inner diameter of the cylinder (especially the inner diameter at the constriction). This results in a limited clamping contact area and uneven distribution of clamping force. During the subsequent impregnation and flipping process, the glass insulator is prone to tilting, sliding, or even falling off due to shift in the center of gravity or inertia, seriously affecting process stability and product consistency.

[0004] Secondly, the notches drilled in the side wall of the cylinder to accommodate the clamping mechanism inevitably weaken the integrity and mechanical strength of the local structure of the glass insulator. Glass, as a brittle material, is extremely sensitive to stress concentration, and the edges of the notches easily become the starting point for crack initiation and propagation. During clamping, if the clamping force applied by the robotic arm is slightly excessive, or if dynamic loads are generated during the flipping motion, the notched area will bear much higher local stress than other parts, leading to structural damage such as microcracks, edge chipping, or even local collapse. This not only affects product yield but may also create safety hazards during operation.

[0005] Furthermore, this clamping method imposes additional constraints on the structural design of glass insulators—specifically sized and positioned notches must be reserved, which not only increases manufacturing complexity but also limits the scope for product structure optimization. At the same time, different specifications or models of insulators often require customized clamping mechanisms and notch parameters, reducing the equipment's versatility and flexible production capabilities. Summary of the Invention

[0006] This invention discloses a glass insulator adhesive impregnation device, which can solve the problems of traditional glass insulator adhesive impregnation devices, which require additional restrictions on the structural design of glass insulators due to the clamping method, and may cause the glass insulators to tilt, slide or even fall off due to center of gravity shift or inertia, as well as weaken the integrity and mechanical strength of the local structure of the glass insulator.

[0012] Preferably, the edge of the upper abutment plate is provided with a edging, and the inner wall dimension of the edging is the same as the top outer wall dimension of the terminal.

[0014] Preferably, the main body of the robotic arm is further provided with a second drive assembly, which is a motor.

[0015] Preferably, the bushing has an annular groove inside, and the upper end of the lifting cylinder has a circular locking block, which is engaged in the groove.

[0016] Preferably, the first fixing plate has a circular structure, and a plurality of first circular holes are equidistantly provided on the edge of the first fixing plate; One end of the abutment rod is provided with a second round hole, which is engaged with the first round hole, and a third round hole is provided in the middle of the abutment rod; The second fixing plate has a circular structure.

The support rod consists of two support plates and two rollers. Each roller is connected to one end of the two support plates, and the two rollers are rotatably installed in the third and fourth circular holes, respectively.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: The equipment includes a robotic arm body with a first drive assembly and a rotating rod. A lifting cylinder is fitted onto the rotating rod and is driven axially upward and downward by the first drive assembly. An inner support mechanism is installed at the bottom of the lifting cylinder and can move synchronously with it. An upper abutment plate is fixed to the upper part of the lifting cylinder, located above the inner support mechanism. The glass insulator to be processed is placed at a predetermined position below the equipment. The first drive assembly drives the lifting cylinder downward: the upper abutment plate first contacts and presses against the outer wall of the terminal top, forming an external limit; simultaneously, the inner support mechanism enters the terminal and expands outward during its continued descent, tightly abutting against the inner wall of the terminal, forming internal support; at this time, the glass insulator is pressed downward from the outside of the terminal by the upper abutment plate, and the inner support mechanism radially supports it from the inside of the terminal, achieving a bidirectional, multi-point, and uniform clamping force distribution. After clamping, the robotic arm body can drive the entire lifting cylinder and the clamped glass insulator to rotate, flip, or tilt via the rotating rod to meet the process requirements of uniform adhesive impregnation; throughout the process, the glass insulator is firmly fixed, with no risk of slippage or displacement.

[0018] The dual clamping mechanism, employing an upper abutment plate pressing the terminal externally and an internal support mechanism supporting the terminal internally, significantly increases the effective contact area. The clamping force works synergistically along the axial and radial directions, resulting in a more even distribution and greatly improving clamping stability, effectively preventing displacement or detachment during flipping. No notches need to be made on the sidewalls of the glass insulator terminals. The internal support mechanism enters axially from the terminal opening, while the upper abutment plate acts on the intact outer wall, avoiding mechanical damage to the glass body, maintaining its structural integrity and mechanical properties, and eliminating micro-cracks and safety hazards caused by notches. This clamping method does not rely on a specific notch structure; it only requires the terminal to have a standard hollow cylindrical shape, including a constricted opening, making it suitable for various specifications of glass insulators. By adjusting the lifting stroke of the lifting cylinder or the size of the internal support mechanism, it can adapt to products with different inner diameters or heights, significantly improving equipment flexibility and versatility, and reducing customization costs.

[0033] Example 1 like Figure 1 , Figure 2 and Figure 3 As shown, a glass insulator adhesive impregnation device includes a robotic arm body 1, on which at least one first drive assembly 11 and a rotating rod 12 are provided; a lifting cylinder 2, which is sleeved on the rotating rod 12, and the first drive assembly 11 drives the lifting cylinder 2 to perform lifting and lowering movements on the rotating rod 12; an inner support mechanism 3, which is installed at the bottom of the lifting cylinder 2; an upper abutment plate 4, which is fixedly installed on the lifting cylinder 2; and a glass insulator 5, which has a terminal 51, which is a hollow cylindrical structure with a constricted top. The first drive assembly 11 drives the lifting cylinder 2 to descend, causing the upper abutment plate 4 to abut against the top outer wall of the terminal 51, and the inner support mechanism 3 enters the interior of the terminal 51 and abuts against the inner wall of the terminal 51.

[0034] In this embodiment, the device includes a robotic arm body 1, on which a first drive assembly 11 and a rotating rod 12 are mounted; a lifting cylinder 2 is sleeved on the rotating rod 12 and is driven to move axially upwards by the first drive assembly 11; an inner support mechanism 3 is installed at the bottom of the lifting cylinder 2 and can move synchronously with it; an upper abutment plate 4 is fixed to the upper part of the lifting cylinder 2 and is located above the inner support mechanism 3. The glass insulator 5 to be processed is placed at a predetermined position below the device, and the first drive assembly 11 drives the lifting cylinder 2 to move downwards: the upper abutment plate 4 first contacts and presses against the outer wall of the top of the terminal 51, forming an external limit; at the same time, the inner support mechanism 3 enters the interior of the terminal 51 and expands outwards during the continued downward movement to tightly abut against the inner wall of the terminal 51, forming an internal support; at this time, the glass insulator 5 is pressed downwards from the outside of the terminal 51 by the upper abutment plate 4, and the inner support mechanism 3 is radially supported from the inside of the terminal 51, realizing a bidirectional, multi-point, and uniform clamping force distribution. After clamping, the main body 1 of the robot arm can rotate, flip or tilt the entire lifting cylinder 2 and the clamped glass insulator 5 through the rotating rod 12 to meet the process requirements of uniform adhesive impregnation; throughout the process, the glass insulator 5 is firmly fixed without the risk of slippage or displacement.

[0035] The dual clamping mechanism, employing an upper abutment plate 4 to press against the terminal 51 and an inner support mechanism 3 to support the terminal 51, significantly increases the effective contact area. The clamping force works synergistically along the axial and radial directions, resulting in a more uniform distribution and greatly improving clamping stability, effectively preventing displacement or detachment during the flipping process. No notches need to be made on the sidewalls of the glass insulator terminal 51. The inner support mechanism 3 enters axially from the opening of the terminal 51, while the upper abutment plate 4 acts on the intact outer wall, effectively avoiding mechanical damage to the glass body, maintaining its structural integrity and mechanical properties, and eliminating micro-cracks and safety hazards caused by notches. This clamping method does not rely on a specific notch structure; it only requires the terminal 51 to have a standard hollow cylindrical shape, including a constricted opening, making it suitable for various specifications of glass insulators. By adjusting the lifting stroke of the lifting cylinder 2 or the size of the inner support mechanism 3, it can adapt to products with different inner diameters or heights, significantly improving the flexibility and versatility of the equipment and reducing customization costs.

[0036] like Figure 4 As shown, the inner support mechanism 3 further includes a first fixed plate 121 disposed at the bottom of the rotating rod 12 and a second fixed plate 21 disposed at the bottom of the lifting cylinder 2. The first fixed plate 121 has a plurality of abutting rods 1211 arranged in a ring at equal intervals, and the second fixed plate 21 has a plurality of support rods 211 arranged in a ring at equal intervals. One end of the support rod 211 is rotatably connected to the second fixed plate 21, and the other end is rotatably connected to the middle of the abutting rod 1211. One end of the abutting rod 1211 is rotatably connected to the first fixed plate 121.

[0037] The first fixing plate 121 is fixed to the bottom of the rotating rod 12 and rotates synchronously with the rotating rod 12 but does not rise or fall; the second fixing plate 21 is fixed to the bottom of the lifting cylinder 2 and rises or falls along the axis of the rotating rod 12 with the lifting cylinder 2. Abutting rods 1211: Multiple rods are arranged in a ring at equal intervals on the first fixed plate 121, one end of which is hinged to the first fixed plate 121 and can rotate. Support rod 211: The number corresponds to the abutment rod 1211. One end is hinged to the second fixing plate 21, and the other end is hinged to the middle of the abutment rod 1211.

[0038] In this embodiment, Initial state: The lifting cylinder 2 is in a high position, the second fixing plate 21 is in a high position, the support rod 211 is almost vertical, the abutment rod 1211 is gathered in the center, the overall outer diameter is the smallest, which makes it easy to insert into the terminal 51 of the glass insulator 5; Clamping stage: The first drive assembly 11 drives the lifting cylinder 2 to move downward, the second fixed plate 21 moves downward synchronously, the support rod 211 is driven downward and rotates around the hinge points at both ends, pushing the middle part of the abutment rod 1211 to swing outward, the abutment rod 1211 rotates around its root, that is, the hinge point with the first fixed plate 121, and the free end opens radially. Final state: The outer side of the abutment rod 1211 is in close contact with the inner wall of the terminal 51, forming a multi-point, symmetrical, and evenly distributed internal support force.

[0039] When the glass insulator needs to be released, the lifting cylinder 2 rises, causing the second fixed plate 21 to move upward. The support rod 211 pulls the middle of the abutment rod 1211 back, and the abutment rod 1211 retracts. The outer diameter of the inner support mechanism decreases and becomes smaller than the opening of the terminal 51, further disengaging from the inner wall of the terminal 51, thus completing the release. The inner support mechanism 3 provides internal radial support force, and the upper abutment plate 4 provides external axial clamping force. The two work together to achieve stable, slip-free clamping of the glass insulator 5, while allowing the entire structure to rotate with the rotating rod 12, meeting the requirements of the impregnation process.

[0040] Furthermore, the top of the terminal 51 is an opening 511, which is a constricted structure. When the first drive assembly 11 drives the lifting cylinder 2 to descend, the multiple abutment rods 1211 are compressed and stretched by the lifting cylinder 2 to form a horizontal support surface 300, and the maximum outer diameter of the horizontal support surface 300 is equal to the maximum inner diameter of the terminal 51. When the first drive assembly 11 drives the lifting cylinder 2 upward, the multiple abutment rods 1211 are pulled and contracted by the lifting cylinder 2, and the maximum outer diameter of the inner support mechanism 3 is smaller than the inner diameter of the opening 511.

[0041] In this embodiment, the top of the terminal 51 of the glass insulator 5 is provided with a constricted opening 511, which forms an inner cavity that decreases in size or has a specific contour. The maximum inner diameter is located at a certain point below the constriction. The inner support mechanism 3 is composed of multiple abutment rods 1211, which are initially retracted and have a small outer diameter. When the first drive assembly 11 drives the lifting cylinder 2 to rise, the second fixing plate 21 moves upward accordingly. The support rod 211 pulls the middle of the abutment rod 1211 upward, causing the abutment rod 1211 to retract inward around its root hinge point. At this time, the maximum outer diameter of the entire inner support mechanism 3 is smaller than the minimum inner diameter of the opening 511, i.e., the inner diameter at the constriction, allowing it to be pulled out or inserted into the terminal 51 without obstruction, avoiding scratching or collision with the inner wall of the glass. As the lifting cylinder 2 descends, the second fixed plate 21 moves downward, pushing the support rod 211 to move outward and downward. The support rod 211 transmits force to the middle of the abutment rod 1211, forcing it to rotate outward around its root. Multiple abutment rods 1211 eventually extend into a nearly horizontal support surface 300, whose maximum outer diameter is precisely equal to the maximum inner diameter of the terminal 51, typically located in the stable section below the constriction. At this point, the abutment rod 1211 and the inner wall of the terminal 51 achieve full-circumference, surface-to-surface contact, forming a uniform and stable radial support force. The upper abutment plate 4 presses against the top outer edge of the terminal 51 to prevent axial movement; the inner support mechanism 3 provides radial constraint and bears the overturning inertial load. It should be noted that as long as the terminal 51 has a standard constricted hollow structure, the abutment rod 1211 can be extended to the corresponding inner diameter position by adjusting the lifting stroke. Different specifications of products only require adjustment of the descent depth; there is no need to modify the insulator structure or replace the fixture body, significantly improving flexible production capabilities. After the abutment rod 1211 extends, it forms a horizontal support surface 300, and its outer diameter precisely matches the maximum inner diameter of the terminal 51, achieving full-circumferential surface contact rather than point or line contact, significantly improving friction and support rigidity; together with the upper abutment plate 4, it completely eliminates the risk of tilting or slippage caused by center of gravity shift. The inner support mechanism 3 has an outer diameter larger than the inner diameter of the opening 511 in the released state, allowing it to move freely in and out; when clamped, it only contacts the complete inner wall, with no local stress concentration source, effectively protecting the brittle structure of the glass and preventing micro-cracks and edge chipping caused by machining defects.

[0042] Furthermore, a soft rubber pad 12111 is provided at the end of the abutment rod 1211 away from the first fixing plate 121.

[0043] In this embodiment, the rubber pad 12111 achieves self-adaptive surface-to-surface contact through elastic deformation, compensating for manufacturing tolerances or assembly deviations and resulting in more uniform clamping force. Simultaneously, its high coefficient of friction significantly enhances anti-slip capability, effectively preventing insulator displacement or detachment, especially under high-speed flipping or tilting conditions. Although this solution eliminates the need for a notch, if only a rigid metal abutment rod is used to directly contact the glass, micro-cracks may still occur due to point contact or hard-on-hard impact during clamping or vibration. The rubber pad, as a flexible buffer layer, transforms concentrated stress into distributed pressure, greatly reducing local pressure and fundamentally avoiding the risk of damage to brittle glass.

[0044] like Figure 5 As shown, the upper abutment plate 4 further includes a cylindrical fixing part 41, and at least one limiting groove 411 is provided on the inner wall of the fixing part 41; at least one positioning hole 412 is provided on the fixing part 41, and the position of the positioning hole 412 corresponds to the position of the limiting groove 411; at least one sub-plate 22 is provided on the outer wall of the lifting cylinder 2, and multiple threaded holes 221 are provided vertically and equidistantly on the sub-plate 22; the sub-plate 22 is fitted into the limiting groove 411; and the sub-plate 22 and the fixing part 41 are fixedly connected by bolts installed in the positioning hole 412 and the threaded hole 221.

[0045] In this embodiment, since the sub-plate 22 is provided with multiple equally spaced threaded holes 221, the user can select the appropriate threaded hole 221 for fixing according to the height or constriction position of the terminal 51 of different models of glass insulators 5; for example, for shorter insulators, the lower threaded hole 221 is selected; for taller insulators, the upper threaded hole 221 is selected; after adjustment, the axial position of the upper abutment plate 4, i.e., the height of the pressing surface, changes accordingly, ensuring that it is always accurately pressed into the ideal position of the top outer edge of the terminal 51. The limiting groove 411 is not only used for installation guidance, but also prevents the sub-plate 22 from rotating circumferentially under torque, ensuring the stability of the upper abutment plate 4 under rotation conditions; the bolt connection provides high tensile and shear strength, ensuring that the connection does not loosen under dynamic loads such as flipping and acceleration.

[0046] Furthermore, the edge of the upper abutment plate 4 is provided with a edging 42, and the inner wall dimension of the edging 42 is the same as the top outer wall dimension of the terminal 51.

[0047] In this embodiment, it should be noted that the inner diameter or inner contour of the edging 42 is completely consistent with the outer dimensions of the top outer wall of the terminal 51, and is usually a cylindrical or conical surface that matches the outer wall of the constricted section. When the lifting cylinder 2 descends, the upper abutment plate 4 descends accordingly, and the edging 42 fits into and tightly fits the top outer periphery of the terminal 51. The edging 42 automatically centers the terminal 51 at the moment of contact, eliminating the initial placement deviation; the edging 42 forms full circumferential contact with the outer wall of the terminal 51, effectively suppressing the slight sway or shaking caused by inertia during the flipping or rotation process; the contact force is evenly distributed along the inner wall of the edging 42, avoiding local high pressure caused by point contact.

[0048] Furthermore, the main body 1 of the robotic arm is provided with a base plate 13, and the first drive assembly 11 is an electric push rod; the first drive assembly 11 is mounted on the upper surface of the base plate 13, and the telescopic rod of the first drive assembly 11 extends from the lower surface of the base plate 13; the upper end of the lifting cylinder 2 is connected to a connecting plate 23, and the telescopic rod of the first drive assembly 11 is fixedly connected to the connecting plate 23, such as by bolts or flanges. The rotating rod 12 passes through the interior of the lifting cylinder 2, but is not fixed to it, only providing rotational support.

[0049] In this embodiment, when the electric push rod extends, the telescopic rod pushes the connecting plate 23 downward, causing the lifting cylinder 2 to descend synchronously along the rotating rod 12; when the electric push rod retracts, the telescopic rod pulls the connecting plate 23 upward, causing the lifting cylinder 2 to rise synchronously. Throughout the process, the lifting cylinder 2 only performs axial linear motion and does not rotate with the electric push rod, ensuring that the movement trajectory of the inner support mechanism 3 and the upper abutment plate 4 is precisely controllable. The electric push rod's stroke, speed, and thrust can be precisely adjusted by a PLC or motion controller.

[0050] like Figure 6 and Figure 7 As shown, the robotic arm body 1 is further provided with a second drive assembly 14, which is a motor. The output end of the second drive assembly 14 is fixedly connected to the upper end of the rotating rod 12 to drive the rotating rod 12 to rotate. A first through hole 131 is provided on the base plate 13, and a second through hole 232 is provided on the connecting plate 23. The rotating rod 12 is movably installed in the first through hole 131 and the second through hole 232. A bushing 231 is provided on the lower surface of the connecting plate 23, and the upper end of the lifting cylinder 2 is rotatably connected to the bushing 231.

[0051] In this embodiment, the first drive assembly 11 is responsible for the lifting motion, driving the lifting cylinder 2 to move axially along the rotating rod 12 to achieve clamping or releasing; the second drive assembly 14 is responsible for the rotational motion, and its output shaft is rigidly connected to the upper end of the rotating rod 12, directly driving the rotating rod 12 to rotate around its own axis.

[0052] A first through hole 131 is provided on the base plate 13, and a second through hole 232 is provided on the connecting plate 23. The rotating rod 12 passes through the first through hole 131 and the second through hole 232, but is not fixed to the connecting plate 23. A bushing 231 is provided on the lower surface of the connecting plate 23, and the upper end of the lifting cylinder 2 is rotatably connected to the bushing 231 through a bearing or clearance fit. Therefore, when the electric push rod is activated, the connecting plate 23 drives the lifting cylinder 2 to move up and down, while the rotating rod 12 remains stationary. When the motor is started, the rotating rod 12 rotates, and drives the glass insulator 5 to rotate synchronously through the inner support mechanism 3, while the lifting cylinder 2 can rotate accordingly or remain relatively stationary, depending on whether it is clamped. The lifting motion is transmitted by the connecting plate 23, and the rotational motion is transmitted by the rotating rod 12. The two are mechanically independent and do not interfere with each other.

[0053] Process execution flow: The electric push rod pushes the lifting cylinder 2 downward, the upper stop plate 4 presses and the inner support mechanism 3 opens to complete the clamping of the glass insulator 5; the motor starts to drive the rotating rod 12 to rotate, the inner support mechanism 3 drives the glass insulator 5 to rotate, and the adhesive is evenly wetted on the outer surface of the glass insulator 5; the motor stops, the electric push rod rises, the clamp is released, and the glass insulator 5 is taken out.

[0054] like Figure 8 As shown, the bushing 231 further has an annular groove 2311 inside, and the upper end of the lifting cylinder 2 is provided with a circular locking block 24, which is fitted into the groove 2311.

[0055] In this embodiment, the locking block 24 is confined between the upper and lower walls of the slot 2311 and cannot detach axially, ensuring that the lifting cylinder 2 is always connected to the connecting plate 23 and will not fall off even when the electric push rod retracts or under vibration conditions; the locking block 24 can rotate freely around the axis of the rotating rod 12 in the slot 2311, so that when the second drive assembly 14 drives the rotating rod 12 to rotate, the inner support mechanism 3 drives the glass insulator 5 to rotate, and the lifting cylinder 2 can rotate synchronously or remain relatively stationary, depending on the clamping state, without mechanical interference.

[0056] like Figure 4As shown, further, the first fixing plate 121 has a circular structure, and a plurality of first circular holes 1212 are equidistantly provided at the edge of the first fixing plate 121; one end of the abutting rod 1211 is provided with a second circular hole 12112, the second circular hole 12112 is fastened to the first circular hole 1212, and a third circular hole 12113 is provided in the middle of the abutting rod 1211; the second fixing plate 21 has a circular structure, and a plurality of connecting blocks 213 are equidistantly provided at the edge of the lower surface of the second fixing plate 21, and a fourth circular hole 2131 is provided on the connecting block 213; the support rod 211 is composed of two support plates 2113 and two roller shafts 2114, each roller shaft 2114 is connected to one end of the two support plates 2113, and the two roller shafts 2114 are respectively rotatably installed in the third circular hole 12113 and the fourth circular hole 2131.

[0057] In this embodiment, one end of the abutment rod 1211 is provided with a second circular hole 12112, which is aligned and fastened with the first circular hole 1212 by a pin or directly, forming a root hinge point, allowing the abutment rod to rotate around this point; a roller shaft 2114 passes through a third circular hole 12113, achieving a hinge with the middle of the abutment rod 1211; another roller shaft 2114 passes through a fourth circular hole 2131, achieving a hinge with the bottom of the connecting block 213; the roller shafts 2114 can rotate freely within the corresponding circular holes, forming a low-friction rotary pair. This is only one specific embodiment of the inner support mechanism 3. Other specific structures can also be used so that when the lifting cylinder 2 descends and squeezes the inner support mechanism 3, the inner support mechanism 3 expands; when the lifting cylinder 2 rises and pulls the inner support mechanism 3, the inner support mechanism 3 contracts and gathers.

Any equivalent structural or procedural transformations made based on the content of the present invention's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
