Description

Technical Field

[0001] This application relates to the field of composite insulator manufacturing technology, and in particular to a glue-fitting machine. Background Technology

[0002] Adhesive bonding is currently the most widely used assembly method for composite insulator products. It mainly utilizes the gelling or solidifying properties of adhesives to fill the gaps between fiberglass pipes and flanges, connecting the two and forming a product that meets mechanical and electrical performance requirements.

[0003] Existing composite insulator gluing methods generally employ vertical gluing, which requires sequentially gluing the flanges at both ends of the composite insulator, resulting in low production efficiency and a low first-pass yield. Current horizontal gluing methods are only suitable for composite insulators with flanges at both ends. For hollow composite insulators with conductive rods, existing horizontal gluing machines cannot achieve the desired gluing effect. Therefore, a new type of gluing machine with a novel structure is needed. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this application is to provide a gluing machine that employs a horizontal gluing process. This machine can simultaneously glu the flanges at both ends of a hollow composite insulator with a conductive rod. By setting up a pressure device, the gluing pressure is kept stable to avoid bias pressure. Furthermore, dynamic pressure is applied throughout the gluing process to prevent flatness errors caused by heat deformation of the heating plate during gluing, effectively improving the product qualification rate. The machine is also easy to operate and has high production efficiency.

[0005] To solve the above-mentioned technical problems, the technical solution adopted in this application is as follows: A binding machine is provided for binding composite insulators. The composite insulator includes an insulator body, a first flange located at one end of the insulator body, a second flange located at the other end of the insulator body, and a conductive rod passing through the inner cavity of the insulator body.

[0006] In one embodiment, the main frame includes a base, an electric cylinder connecting plate, a fixing plate, and a plurality of first guide rods. The base is arranged along a first direction, and the electric cylinder connecting plate and the fixing plate are spaced apart on the base along the first direction. The plurality of first guide rods are all fixedly connected between the electric cylinder connecting plate and the fixing plate, and the plurality of first guide rods are all arranged along the first direction. The plurality of first guide rods pass through a first heating device so that the first heating device is located between the electric cylinder connecting plate and the fixing plate. The first guide rods are used to guide the first heating device to move along the first direction.

[0007] In one embodiment, the first heating device includes a first pressure plate, an intermediate transition plate, and a plurality of second guide rods.

[0010] In one embodiment, the first pressure plate is further provided with a first positioning mechanism, which includes two positioning elements, a positioning rod and a positioning handwheel. The positioning rod and the positioning handwheel are used to drive the two positioning elements to move synchronously in opposite directions or in opposite directions. The two positioning elements cooperate to fix the first flange.

[0011] In one embodiment, the second heating device includes a second pressure plate, a second heat insulation plate, and a second heating plate that are fixedly connected in sequence.

[0028] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0029] See Figures 1-2In one embodiment, a gluing machine 100 is provided for gluing composite insulators 20. The composite insulator 20 includes an insulator 21, a first flange 22 located at one end of the insulator 21, a second flange 23 located at the other end of the insulator 21, and a conductive rod 24 passing through the inner cavity of the insulator 21. One end of the conductive rod 24 is fixedly connected to the second flange 23, and the other end passes through the inner cavity of the insulator 21 and extends out of the insulator 21 from the first flange 22. The gluing machine 100 includes an electric cylinder device 101, a main frame 110, a first heating device 120, a second heating device 130, a first support device 140, a second support device 150, and a pressure device 160. The pressure device 160 is used to apply pressure to the composite insulator 20 to keep the pressure stable during the gluing process, avoid bias pressure, and implement dynamic pressure throughout the gluing process, which can prevent flatness errors caused by deformation of the heating plate and effectively improve the gluing qualification rate. The electric cylinder device 101 is located outside the main frame 110 and is used to provide power to the binding machine 100. A first heating device 120, a first support device 140, and a second heating device 130 are movably and sequentially spaced along the length of the main frame 110. A second support device 150 is fixedly connected to the main frame 110 and located between the first support device 140 and the second heating device 130. Specifically, the first support device 140, located between the first heating device 120 and the second heating device 130, is used to support the insulator 21; the second support device 150, located between the first support device 140 and the second heating device 130, is used to support the conductive rod 24.

[0030] For ease of explanation, the length direction of the main frame 110 is defined as the first direction F1, and the width direction of the main frame 110 is defined as the second direction F2. The first direction F1 and the second direction F2 are both located on the same horizontal plane, and the second direction F2 is perpendicular to the first direction F1.

[0031] The main frame 110 includes a base 111, an electric cylinder connecting plate 112, a fixing plate 113, and several first guide rods 114. The base 111 is a metal frame structure, arranged along the first direction F1, and is used to support all the devices on the binding machine 100. The electric cylinder connecting plate 112 is fixedly connected to the edge of one end of the base 111. The electric cylinder device 101 and the electrical cabinet 102 are both connected to the side of the electric cylinder connecting plate 112 away from the base 111, and are used to provide power support to the binding machine 100. The fixing plate 113 is fixedly connected to the base 111 and is spaced apart from the electric cylinder connecting plate 112 in the first direction F1. The positions of the electric cylinder connecting plate 112 and the fixing plate 113 are relatively fixed, which is suitable for binding composite insulators 20 within a certain length range. In this embodiment, the electric cylinder connecting plate 112 and the fixing plate 113 are both rectangular plates, and the electric cylinder connecting plate 112 and the fixing plate 113 are fixedly connected by four first guide rods 114, so that the main frame 110 is fixed as a whole. The four first guide rods 114 are arranged in a rectangular pattern, with their ends forming the four vertices of the rectangle. This ensures a relatively fixed position and a more stable connection between the electric cylinder connecting plate 112 and the fixed plate 113. In this embodiment, the two ends of the four first guide rods 114 are fixedly connected to the electric cylinder connecting plate 112 and the fixed plate 113, respectively. All four first guide rods 114 are arranged along the first direction F1. The four first guide rods 114 pass through the first heating device 120, positioning the first heating device 120 between the electric cylinder connecting plate 112 and the fixed plate 113. The first guide rods 114 guide the first heating device 120 to move along the first direction F1, ensuring that the axis of the first flange 22 is parallel to the first direction F1. In other embodiments, the number of first guide rods is not specifically limited, as long as they can guide the movement direction of the heating device.

[0032] Specifically, the first flange 22 is clamped and fixed on the first heating device 120, the insulator 21 of the composite insulator 20 is supported on the first support device 140, the second flange 23 is clamped and fixed on the second heating device 130, a conductive rod 24 is fixedly connected to one end of the second flange 23 near the insulator 21, and the conductive rod 24 is supported on the second support device 150, so that the second flange 23 and the conductive rod 24 are stably supported and the length direction of the conductive rod 24 is parallel to the first direction F1, that is, the first flange 22, the second flange 23, the conductive rod 24 and the insulator 21 are coaxial. The pressure device 160 drives the first heating device 120 and the second heating device 130 to move along the first direction F1, moving the first flange 22 to be assembled and fixed to one end of the insulator 21, and the second flange 23 to be assembled and fixed to the other end of the insulator 21. The first heating device 120 and the second heating device 130 clamp and fix the first flange 22 and the second flange 23 at both ends of the insulator 21, respectively. At the same time, the first heating device 120 and the second heating device 130 heat the first flange 22 and the second flange 23, respectively, to achieve the gluing of the composite insulator 20. The movable arrangement of the first heating device 120 and the second heating device 130 allows them to stably clamp composite insulators of different lengths, thus enabling the gluing machine 100 to be applicable to the gluing of composite insulators of different lengths, expanding the application range of the gluing machine 100. The axial direction of the composite insulator 20 is parallel to the first direction F1, that is, the length direction of the main frame 110 and the axial direction of the composite insulator 20 are in the same direction.

[0033] The base 111 is a rectangular frame structure made of metal. The base 111 includes two first frames 1111 positioned along a first direction F1, parallel to each other and spaced apart along a second direction F2. Two second frames 1112 are fixedly connected to the ends of each of the two first frames 1111, both parallel to the second direction F2. The two first frames 1111 and the two second frames 1112 constitute the rectangular frame structure of the base 111. The electric cylinder connecting plate 112 is fixedly connected to one of the second frames 1112. The upper surfaces of the two first frames 1111 and the upper surfaces of the two second frames 1112 are located in the same horizontal plane.

[0034] Two first guide rails 115 are provided on the main frame 110. The first guide rails 115 are fixed above the base 111 along a first direction F1. Specifically, the two first guide rails 115 are spaced apart on the two first frames 1111 along a second direction F2, and the first guide rails 115 are located between the electric cylinder connecting plate 112 and the fixing plate 113. The first heating device 120 is slidably connected to the two first guide rails 115, so that the first heating device 120 can move along the first direction F1, and the first heating device 120 can move back and forth between the electric cylinder connecting plate 112 and the fixing plate 113. In this embodiment, the two first guide rails 115 are disposed above the base 111, meaning that the height of the two first guide rails 115 is higher than the top surface of the base 111, that is, the height of the two first guide rails 115 is higher than the upper surface of the first frame 1111. For example, they can be located at a position of one-quarter, one-third, or one-half of the overall height of the first frame 1111, as long as they are not located at the bottom of the first frame 1111. Compared with the structure of the bottom guide rail in the traditional glue binding machine, this can avoid glue from splashing out of the flange and dripping onto the bottom guide rail during the glue binding operation, such as when glue injection begins or stops, which would prevent the first heating device 120 from moving smoothly along the first direction F1.

[0035] The base 111 also includes two third frames 1113, both of which are parallel to the first frame 1111. The two third frames 1113 are spaced apart between the two first frames 1111 along the second direction F2, and their ends are respectively abutted and fixed to the two second frames 1112. Meanwhile, the upper surface of the third frame 1113 is lower than the upper surface of the first frame 1111, meaning the height of the third frame 1113 is less than the height of the first frame 1111. The upper surface of each of the two third frames 1113 is provided with a second guide rail 116 extending along the first direction F1. The second guide rail 116 is located between the electric cylinder connecting plate 112 and the fixing plate 113, and along the second direction F2, since the two third frames 1113 are located between the two first frames 1111, the two second guide rails 116 are also located between the two first guide rails 115. The first support device 140 is slidably connected to two second guide rails 116, enabling the first support device 140 to move along the first direction F1, and the first support device 140 to move back and forth between the first heating device 120 and the fixing plate 113. The two second guide rails 116 are positioned at a height higher than the upper surface of the third frame 1113, and their specific arrangement is similar to that of the first guide rail 115, and will not be described again.

[0036] See Figures 1-3The first heating device 120 includes a first pressure plate 121, an intermediate transition plate 122, several second guide rods 123, and a positioning adjustment device 124. In this embodiment, the first pressure plate 121 is an irregular rectangular plate with grooves on both sides, used to clamp and fix the first flange 22. The intermediate transition plate 122 is a regular rectangular plate. Both the first pressure plate 121 and the intermediate transition plate 122 are movably mounted on the first guide rail 115 via sliders and are movably connected to the main frame 110. The first pressure plate 121 and the intermediate transition plate 122 are spaced apart along the first direction F1, with the intermediate transition plate 122 located close to the electric cylinder connecting plate 112. The first pressure plate 121 and the intermediate transition plate 122 are fixedly connected by four second guide rods 123, allowing the first pressure plate 121 and the intermediate transition plate 122 to move as a whole on the base 111 along the first direction F1. The four second guide rods 123 are arranged in a rectangular pattern, with the ends of the four second guide rods 123 forming the four vertices of the rectangle. This makes the position between the first pressure plate 121 and the intermediate transition plate 122 relatively fixed and the connection more stable. In other embodiments, the four second guide rods can also be arranged in other shapes, which is not limited here, and the number of second guide rods is not specifically limited, as long as they can fix the first pressure plate and the intermediate transition plate. Further, each of the four vertices of the first pressure plate 121 is provided with a first through hole 125, and each of the four vertices of the intermediate transition plate 122 is provided with a second through hole 126. After the first through holes 125 and the second through holes 126 are matched and corresponded, the first guide rods 114 are respectively inserted to fix the first heating device 120 on the base 111, while ensuring that the axis of the first flange 22 clamped on the first heating device 120 is parallel to the first direction F1.

[0037] Combination Figure 4The positioning adjustment device 124 is fixedly connected between the first pressure plate 121 and the intermediate transition plate 122, that is, the positioning adjustment device 124 is fixedly connected to the side of the first pressure plate 121 away from the first support device 140. The positioning adjustment device 124 includes a connecting seat 1241, a base 1242 and a positioning block 1243. The connecting seat 1241 is fixedly connected between the first pressure plate 121 and the intermediate transition plate 122, and the connecting seat 1241 is arranged along the first direction F1. The base 1242 is slidably connected to the connecting seat 1241. Specifically, a third guide rail 1244 is provided above the connecting seat 1241. The third guide rail 1244 is also arranged along the first direction F1. The base 1242 is movably arranged on the third guide rail 1244 by a slider, so that the base 1242 can move along the first direction F1 on the third guide rail 1244. The base 1242 includes a first connecting plate and a second connecting plate that are connected to each other. The first connecting plate and the second connecting plate form an L-shaped structure. The first connecting plate is movably connected to the third guide rail 1244. The second connecting plate is fixedly connected to a positioning block 1243. The positioning block 1243 is provided with a first through hole 12431 for fixing the positioning block 1243 to the detachably connected second connecting plate. The positioning block 1243 is also provided with a second through hole 12432 for positioning connection with the end of the conductive rod 24.

[0038] Specifically, the end of the conductive rod 24 extending out of the first flange 22 is provided with a positioning hole for positioning and installing the composite insulator 20. In the traditional composite insulator gluing method, since there is no positioning device for the positioning hole at the end of the conductive rod, it is usually necessary to perform secondary processing on the conductive rod to form the positioning hole after the conductive rod is glued, that is, after the position of the conductive rod and the first flange are relatively fixed, according to the usage requirements. In this application, the positioning hole can be formed in one step during the initial processing of the conductive rod 24. When the composite insulator 20 is glued on the gluing machine 100, a positioning adjustment device 124 is set up, and a pin (not shown) is inserted into the second through hole 12432 of the positioning block 1243. When the conductive rod 24 is driven to pass through the inner cavity of the insulator 21 and extend out of the first flange 22, the positioning hole at the end of the conductive rod 24 matches and is fixed with the pin, so that the position of the conductive rod 24 is fixed, and there is no need to process the positioning hole after the conductive rod 24 is glued and fixed. Therefore, by installing a positioning adjustment device 124 on the gluing machine 100, positioning holes can be formed during the processing of the conductive rod 24. During gluing, the conductive rod 24 only needs to be accurately positioned by the positioning adjustment device 124 before gluing, thus eliminating the need for further processing of the conductive rod 24. This improves the production efficiency of the composite insulator 20 and reduces its production cost. Furthermore, the positioning block 1243 is detachably fixed to the base 1242, allowing for the replacement of the corresponding positioning block 1243 to match different specifications of the composite insulator 20, resulting in greater versatility.

[0039] Continue reading Figure 1 and Figure 2 The pressure device 160 driving the first heating device 120 is the first pressure device 161. The first pressure device 161 is fixedly connected between the electric cylinder connecting plate 112 and the intermediate transition plate 122, specifically located on the side of the intermediate transition plate 122 away from the first pressure plate 121. The first pressure device 161 applies pressure directly to the intermediate transition plate 122, thereby applying pressure to the entire first heating device 120, and then applying adhesive pressure to the first flange 22 clamped on the first heating device 120, so that the first flange 22 and the insulator 21 are in close contact, thereby ensuring that the mating position of the first flange 22 when it is sleeved on the outer periphery of the insulator 21 meets the design requirements of the composite insulator 20, and ensuring the adhesive quality.

[0040] Combination Figure 5 The first pressure device 161 includes a drive rod 1611, a pressure head 1612, and a pressure sensor 1613. The drive rod 1611 drives the pressure head 1612 to move the first heating device 120 along the first direction F1 and provides adhesive pressure during the adhesive bonding process. The pressure of the first pressure device 161 is adjustable in the range of 0.5 to 5T to meet the adhesive bonding requirements of different types of composite insulators.

[0041] The drive rod 1611 has a long rod-shaped structure. The end of the drive rod 1611 near the pressure head 1612 has a circular cross-section for easy connection to the pressure head 1612. The other end has a curved rectangular cross-section, meaning one pair of opposite sides are straight lines and the other pair of opposite sides are curved, ensuring a reliable and slip-free connection between the drive rod 1611 and the electric cylinder connecting plate 112. The pressure head 1612 has a cylindrical structure. A connecting block 16111 is provided at the end of the drive rod 1611 that contacts the pressure head 1612 for fixed connection. The connecting block 16111 has a cylindrical structure, and the diameter of its cross-section is larger than the diameter of the cross-section at the end of the drive rod 1611 near the pressure head 1612. In other embodiments, the shapes of the drive rod and the connecting block can also be other shapes, such as a prism for the drive rod and a cuboid for the connecting block. No specific limitations are imposed here; the actual requirements shall prevail.

[0042] A pressure sensor 1613 is disposed between the pressure head 1612 and the first heating device 120. Specifically, the first pressure device 161 further includes a pressure plate 1614, which is a rectangular plate. The first pressure device 161 is connected to the first heating device 120 through the pressure plate 1614. The cross-section of the pressure plate 1614 is larger than the cross-section of the pressure head 1612. The pressure transmitted through the pressure plate 1614 can ensure the uniformity, stability, and continuity of pressure during the gluing process. The pressure sensor 1613, disposed between the pressure head 1612 and the pressure plate 1614, can accurately sense the pressure between the first pressure device 161 and the first heating device 120. In this embodiment, the accuracy of the pressure sensor 1613 is 100N, and it can work with the drive rod 1611 to sense and adjust the gluing pressure applied by the first pressure device 161. When the pressure detected by the pressure sensor 1613 is insufficient to meet the required bonding pressure, a signal is transmitted to the electrical cabinet 102. This controls the drive rod 1611 to drive the pressure head 1612 to continuously apply pressure to the first heating device 120, causing the first heating device 120 to move along the first direction F1 towards the fixed plate 113 until the pressure detected by the pressure sensor 1613 reaches the required bonding pressure. When the pressure exceeds the required bonding pressure, the drive rod 1611 immediately stops applying pressure and releases the pressure to the required level. This ensures that the pressure remains stable throughout the bonding process, eliminating the flatness error between the first flange 22 and the insulator 21 caused by the deformation of the heating plate due to heat during the bonding process after a single pressure application in existing bonding machines. Furthermore, manual monitoring is unnecessary, saving labor costs. In other embodiments, the accuracy of the pressure sensor can also be of other types, as long as it meets the bonding requirements of the composite insulator.

[0043] The first pressure device 161 also includes a locking block 1615. The locking block 1615 is a U-shaped block with one end closed and the other end open. The cross-section of the open end is an L-shape with two openings facing each other. The distance between the long sides of the two L-shapes (the sides extending along the first direction F1) is the same as the diameter of the cross-section of the connecting block 16111. The distance between the closest ends of the two short sides of the two L-shapes (the sides extending along the second direction F2) is the same as the diameter of the cross-section of the drive rod 1611 near the pressure head 1612. When the locking block 1615 is fixed to the pressure head 1612, a stepped receiving cavity is formed between the locking block 1615 and the pressure head 1612. The drive rod 1611 and the connecting block 16111 are precisely locked in the stepped receiving cavity. During assembly, first, the locking block 1615 is fixedly connected to the pressure head 1612. Then, the connecting block 16111 is snapped into the stepped receiving cavity for easy positioning. Next, the connecting block 16111 is fixedly connected to the pressure head 1612, thus achieving a fixed connection between the drive rod 1611 and the pressure head 1612. Furthermore, since a stepped receiving cavity is formed between the locking block 1615 and the pressure head 1612, the connecting block 16111 can also be directly snapped into the stepped receiving cavity, achieving a fixed connection between the drive rod 1611 and the pressure head 1612 without further fixing.

[0044] The drive rod 1611 is driven by a servo motor, which allows for precise control of its extension and retraction distance. Together with the pressure head 1612, pressure plate 1614, and pressure sensor 1613, it can precisely apply pressure to the first heating device 120, providing stable adhesive bonding pressure. In other embodiments, the pressure device can be driven by other types of motors or other driving equipment, as long as it enables the first and second heating devices to clamp the composite insulator and maintain stable adhesive bonding pressure.

[0045] In this embodiment, the locking block 1615 is fixedly connected to the pressure head 1612, the pressure head 1612 is fixedly connected to the pressure plate 1614, and the pressure plate 1614 is fixedly connected to the first heating device 120 by bolts. In other embodiments, the locking block is fixedly connected to the pressure head, the pressure head is fixedly connected to the pressure plate, and the pressure plate is fixedly connected to the first heating device by means of clamping, welding, etc. Alternatively, the locking block may not be provided, and the connecting block may be directly fixedly connected to the pressure head. As long as the respective functions can be achieved, no specific restrictions are imposed here.

[0046] In other embodiments, the components of the pressure device can also be other structures, such as triangular prisms, pentagonal prisms, etc., as long as they can cooperate with each other to achieve the function of the pressure device, and no specific restrictions are made here.

[0047] Continue to combine Figure 6The first heating device 120 clamps and fixes the first flange 22 through the first pressure plate 121 and heats the first flange 22, so that the first flange 22 is glued and fixed to one end of the insulator 21. The first pressure plate 121 includes a first body 1211, and four protruding side blocks 1212 are provided at the four corners of the first body 1211. Each of the four side blocks 1212 is provided with a first through hole 125 for passing through four first guide rods 114 respectively, so that the first pressure plate 121 can move along the first guide rods 114, and the first heating device 120 is movably mounted on the main frame 110. A first heat insulation plate 1213 and a first heating plate 1214 are fixedly mounted on the first body 1211. The first heating plate 1214, the first heat insulation plate 1213, and the first body 1211 are sequentially and fixedly connected, and are positioned on the side of the first body 1211 facing the first support device 140, so that the first heating plate 1214 directly contacts the first flange 22 of the composite insulator 20 for heating. The first body 1211 is movably connected to the main frame 110. The arrangement of the first body 1211 and the first heat insulation plate 1213 is to prevent the first heating plate 1214 from contacting other components, thereby reducing heat loss. Furthermore, the movable connection between the first body 1211 and the main frame 110, rather than the direct movable connection between the first heating plate 1214 and the main frame 110, also prevents the first heating plate 1214 from contacting other components, further reducing heat loss.

[0048] The first heating plate 1214 is a rectangular plate used to heat the first flange 22 during the gluing process. A heating tube is installed inside the first heating plate 1214. In this embodiment, the heating tube inside the first heating plate 1214 is a resistance heating tube, which has high heating efficiency, automatic temperature control, and is easy to install and maintain. In other embodiments, other types of heating tubes can be used, as long as they can reach the temperature required for gluing the first flange; no limitation is made here. The first heat insulation plate 1213 is a rectangular plate with the same length and width as the first heating plate 1214. The first heat insulation plate 1213 prevents heat transfer between the first heating plate 1214 and the first body 1211, reducing heat loss and improving heating efficiency.

[0049] The first pressure plate 121 is also provided with two protrusions 1215. These two protrusions 1215 are located on the first body 1211, above and below the first heat insulation plate 1213 and the first heating plate 1214, respectively. Each protrusion 1215 has a cuboid structure, with a length equal to that of the first heat insulation plate 1213 and the first heating plate 1214, and a thickness equal to the sum of the thicknesses of the first heat insulation plate 1213 and the first heating plate 1214. The two protrusions 1215 clamp the first heat insulation plate 1213 and the first heating plate 1214, thus further securing them to the first body 1211 and ensuring a reliable connection. Furthermore, the two protrusions 1215 abut against both sides of the first heating plate 1214, further insulating it, reducing heat loss, and improving heating efficiency. The protrusions 1215 can also be made of insulating material for even better insulation.

[0050] In this embodiment, the first heating plate 1214 and the first heat insulation plate 1213 are fixedly connected to the first body 1211, and the first body 1211 and the protrusion 1215 are also fixedly connected by bolts. In other embodiments, the first heating plate, the first heat insulation plate, the first body, and the protrusion can also be of other shapes. The first heating plate, the first heat insulation plate, and the first body, as well as the first body and the protrusion, can also be connected by means of snap-fitting or other methods. Alternatively, the protrusion can be omitted, as long as a reliable connection of the first heating plate, the first heat insulation plate, and the first body can be achieved, and their respective functions can be realized.

[0051] The first pressure plate 121 is further provided with a first positioning mechanism 1216 for fixing the first flange 22. The first positioning mechanism 1216 includes two positioning elements 12161, a positioning rod 12162, and a positioning handwheel 12163. The positioning rod 12162 and the positioning handwheel 12163 are used to drive the two positioning elements 12161 to move synchronously in opposite directions. Through the bidirectional synchronous adjustment of the two positioning elements 12161, the first flange 22 can be quickly fixed on the first pressure plate 121, and the operation is simple.

[0052] The first positioning mechanism 1216 is located on the horizontal center line of the first pressure plate 121. The positioning rod 12162 is horizontally inserted between the first heat insulation plate 1213 and the first heating plate 1214 and is located at the horizontal center line of the first heating plate 1214. Two through slots for accommodating the positioning members 12161 are also provided at the horizontal center line of the first heating plate 1214. The two positioning members 12161 move synchronously towards or away from each other in the two through slots. The two positioning members 12161 are movably connected to the positioning rod 12162. The positioning handwheel 12163 is used to adjust the relative distance between the two positioning members 12161; that is, by rotating the positioning handwheel 12163, the two positioning members 12161 move synchronously towards or away from each other along the positioning rod 12162. When the diameter of the first flange 22 to be glued is small, the two positioning pieces 12161 are adjusted to move synchronously towards each other along the positioning rod 12162; when the diameter of the first flange 22 to be glued is large, the two positioning pieces 12161 are adjusted to move synchronously in opposite directions along the positioning rod 12162. By synchronously adjusting the relative distance between the two positioning pieces 12161, the rapid installation of first flanges 22 of different specifications can be achieved. The boundary of the through groove on the first heating plate 1214 can limit the minimum and maximum distance between the two positioning pieces 12161, avoiding collisions between the two positioning pieces 12161 that could damage the equipment and prevent uniform heating. Specifically, in this embodiment, the positioning rod 12162 is a lead screw with reverse threads, and the positioning piece 12161 has a matching screw hole, in which the lead screw passes. Of course, the first positioning mechanism can also adopt other structures, as long as it can adjust the position of the positioning flange.

[0053] Each positioning element 12161 has a set of mounting holes, each set including threaded holes and through holes, used to fix the first flange 22 with different structural forms. Specifically, the first flange 22 is provided with several symmetrical flange mounting holes (not shown in the figure). Currently, flange mounting holes on the market are usually threaded holes or through holes. When the flange mounting holes on the first flange 22 are threaded holes, rotating the positioning handwheel 12163 makes the two through holes on the two positioning elements 12161 correspond to the two flange mounting holes on the first flange 22 and the fixing element passes through. Then, rotating the positioning handwheel 12163 makes the fixing element lock into the corresponding through hole and flange mounting hole, thereby locking the first flange 22 and realizing the installation and fixation of the first flange 22. When the flange mounting holes on the first flange 22 are through holes, rotating the positioning handwheel 12161 makes the fixing element lock into the corresponding through hole and flange mounting hole, thereby locking the first flange 22 and realizing the installation and fixation of the first flange 22. Handwheel 12163 aligns the two threaded holes on the two positioning parts 12161 with the two flange mounting holes on the first flange 22 and allows the fixing parts to pass through. Then, rotating the positioning handwheel 12163 causes the fixing parts to lock and thus lock the first flange 22, thereby achieving the installation and fixation of the first flange 22. That is, the fixing parts pass through both the threaded holes and the through holes, which can ensure that after adjusting the distance between the two positioning parts 12161 by the positioning handwheel 12163, the first flange 22 can be locked with the positioning parts 12161, thus preventing the first flange 22 from slipping between the first flange 22 and the first heating plate 1214 during the gluing process, which would result in product defects.

[0054] In this embodiment, the fastener is a bolt. In other embodiments, the fastener may also be a pin or other structure. The first positioning mechanism may also be other structures, as long as it can achieve a reliable connection between the first flange and the first pressure plate. No specific restrictions are imposed here.

[0055] Continue reading Figure 6 A temperature sensor 1217 is also provided on the first pressure plate 121, and the temperature sensor 1217 is located on the first body 1211. The temperature sensor 1217 can monitor the surface temperature of the first flange 22. When the temperature does not reach the temperature required for gluing, the first heating plate 1214 is controlled to continue to heat up through the electrical cabinet 102. When the temperature exceeds the set temperature, the first heating plate 1214 is controlled to stop heating immediately, without the need for manual monitoring, saving labor costs.

[0056] In this embodiment, the temperature sensor 1217 is an infrared temperature sensor, employing non-contact temperature measurement. This avoids affecting the bonding condition of the first flange 22 and offers advantages such as a wide measurement range, fast measurement speed, high accuracy, and high sensitivity. In other embodiments, the temperature sensor can be other types of sensors, such as thermocouples or thermistors, as long as they can monitor the bonding temperature of the first flange in real time and accurately. It can also be placed in other locations to monitor the temperature; no specific limitations are imposed here.

[0057] The first pressure plate 121 is further provided with a glue receiving groove 1218. The glue receiving groove 1218 is fixed on the first body 1211 and located below the first heating plate 1214 and extends along the first direction F1 to the outside of the first heating plate 1214. This allows the glue receiving groove 1218 to be used to receive the glue overflowing from the first flange 22. It can ensure that the glue receiving groove 1218 can move synchronously with the first body 1211 along the first direction F1 and is always located below the first heating plate 1214. That is, when the first flange 22 is fixed on the first heating plate 1214 and glued to the insulator 21, the glue receiving groove 1218 is always located below the first flange 22, so as to receive the glue overflowing from the first flange 22 in time and avoid the glue dripping on the ground and making it difficult to clean.

[0058] Continue to combine Figure 1 and Figure 7 The second heating device 130 includes a second pressure plate 131, a second heat insulation plate 132, and a second heating plate 133, which are fixedly connected in sequence. The second heating plate 133 is disposed facing the second support device 150. The second heating device 130 clamps and fixes the second flange 23 through the second pressure plate 131 and heats the second flange 23, so that the second flange 23 is glued and fixed to the other end of the insulator 21. The second pressure plate 131 includes a second body 1311 and two auxiliary plates 1312. The second body 1311 is a rectangular plate. The two auxiliary plates 1312 are spaced apart along the second direction F2 and are fixedly connected to the two side edges of the second body 1311 respectively. The two auxiliary plates 1312 are located on the side of the second body 1311 facing the first heating device 120, and the plate surfaces of the two auxiliary plates 1312 are parallel to each other. The second body 1311 is fixed with a second heat insulation plate 132 and a second heating plate 133. The second heating plate 133, the second heat insulation plate 132 and the second body 1311 are fixedly connected in sequence. The second heating plate 133 is arranged facing the first heating device 120 so as to directly contact the second flange 23 of the composite insulator 20 for heating. The second body 1311 is movably connected to the main frame 110.

[0059] Specifically, the base 111 is provided with two fourth guide rails 117. The fourth guide rails 117 extend along the first direction F1 and are fixed above the base 111. The two fourth guide rails 117 are spaced apart along the second direction F2, and in the second direction F2, the two fourth guide rails 117 are located between the two first guide rails 115. In the first direction F1, the fourth guide rails 117 are located between the first support device 140 and the second frame 1112 on the base 111 away from the electric cylinder connecting plate 112. The second heating device 130 is slidably connected to the two fourth guide rails 117 through the second pressure plate 131. That is, the second pressure plate 131 is movably set on the fourth guide rails 117 through the slider, so that the second heating device 130 can move along the first direction F1, and the second heating device 130 moves back and forth between the first support device 140 and the second frame 1112 on the base 111 away from the electric cylinder connecting plate 112. Meanwhile, in the vertical direction, the fourth guide rail 117 is positioned higher than the first guide rail 115. The fourth guide rail 117 is mounted on a metal frame support 118 provided on the base 111. By positioning the two fourth guide rails 117 between the two first guide rails 115, and with the fourth guide rail 117 positioned higher than the first guide rail 115, interference between the second guide rail 116 and the fourth guide rail 117, which are also positioned between the two first guide rails 115, is avoided. The structure and arrangement of the fourth guide rail 117 are similar to those of the first guide rail 115 and will not be described further.

[0060] The second body 1311 and the second heat insulation plate 132 are both designed to prevent the second heating plate 133 from contacting other components, thus reducing heat loss. Similarly, the second body 1311 is movably connected to the main frame 110, rather than the second heating plate 133 being directly movably connected to the main frame 110, also to prevent the second heating plate 133 from contacting other components and reduce heat loss. The structure and arrangement of the second heat insulation plate 132 are similar to those of the first heat insulation plate 1213, and the structure and arrangement of the second heating plate 124 are similar to those of the first heating plate 1214, and will not be described further.

[0061] The second pressure plate 131 further includes a base plate 1313, which is located at the bottom of the second body 1311 and the two auxiliary plates 1312, and connects the second body 1311 and the two auxiliary plates 1312. A second positioning mechanism 1314 is provided on the base plate 1313 for fixing the second flange 23. The second positioning mechanism 1314 includes a bottom support 13141 and two side supports 13142. The bottom support 13141 is provided on the base plate 1313, and the two side supports 13142 are respectively provided at both ends of the bottom support 13141 along the second direction F2. The two sides of the bottom support 13141 are respectively fixedly connected to the two auxiliary plates 1312. The two auxiliary plates 1312 fix the bottom support 13141 to the second pressure plate 131, thereby making the entire second positioning mechanism 1314 stable on the second pressure plate 131, and able to clamp the second flange 23 more stably. The inner surfaces of both side supports 13142 are beveled, forming a V-shaped support surface suitable for clamping flanges of various profiles of the composite insulator 20. Elastic pads are also provided on the inner surfaces of the two side supports 13142 to prevent the second flange from being bumped or damaged due to excessive clamping. The side supports 13142 are detachably fixed to the bottom support 13141. When the outer circumference of the second flange has an irregular structure, the side supports can be designed to fit the structure of that second flange, expanding the versatility of the second positioning mechanism 1314.

[0062] Continue reading Figure 7 The pressure device 160 driving the second heating device 130 is a second pressure device 162. The second pressure device 162 is fixedly connected to the side of the second pressure plate 131 away from the second support device 150. The second pressure device 162 applies pressure to the second heating device 130, thereby applying adhesive pressure to the second flange 23 clamped on the second heating device 130, ensuring tight contact between the second flange 23 and the insulator 21. This guarantees that the mating position of the second flange 23 on the insulator 21 meets the design requirements of the composite insulator 20, ensuring adhesive quality. The structure of the second pressure device 162 is similar to that of the first pressure device 161, and will not be described in detail here.

[0063] See Figure 1 and Figure 8Two first support devices 140 are spaced apart along a first direction F1 between the first pressure plate 121 and the fixed plate 113 to support the insulator 21, so that both ends of the insulator 21 are respectively fitted and fixed to the first flange 22 and the second flange 23. The first support device 140 includes a bracket 141, a first movable support 142, a second movable support 143, and a first support part 144. The bracket 141 is slidably connected to the main frame 110. Specifically, the bracket 141 is slidably connected to two second guide rails 116 through a slider, so that the first support device 140 is movably mounted on the main frame 110 along the first direction F1, and the first support device 140 moves back and forth between the first pressure plate 121 and the fixed plate 113.

[0064] The first movable support 142 is movably mounted on the bracket 141 along the second direction F2, and the second movable support 143 is movably mounted on the first movable support 142 along the vertical direction. A vertically arranged guide frame 147 is fixedly connected to the first movable support 142, and the second movable support 143 is slidably connected to the guide frame 147, allowing the second movable support 143 to move back and forth along the vertical direction. Specifically, the first support device 140 also includes a first handwheel 145 and a second handwheel 146. Rotating the first handwheel 145 controls the movement of the first movable support 142 along the second direction F2, and rotating the second handwheel 146 controls the up and down movement of the second movable support 143 along the vertical direction. The insulator 21 is moved along the second direction F2 and the vertical direction by the first moving bracket 142 and the second moving bracket 143. This facilitates the adjustment of the concentricity between the insulator 21 placed on the first support device 140 and the first flange 22 fixed on the first heating device 120, ensuring smooth subsequent gluing. It also facilitates the hoisting of the composite insulator 20 by adjusting the distance between the composite insulator 20 and the various components of the gluing machine 100, preventing collisions and damage to the composite insulator 20 during hoisting and transportation. Since the first support device 140 mainly supports the insulator 21, its movement along the first direction F1 can be roughly adjusted manually, i.e., manually pushing the first support device 140 to slide along the two second guide rails 116, as long as it can stably support the composite insulator 20. In other embodiments, servo motors can also be used to control the movement of the first moving bracket along the second direction, the second moving bracket along the vertical direction, and the first support device along the first direction, achieving automated operation and precise control of the movement distance.

[0065] The first support portion 144 is located on the second movable bracket 143. The first support portion 144 is a V-shaped plate. Since the insulator 21 is usually a cylindrical structure, the V-shaped opening of the first support portion 144 allows the insulator 21 to be held in place when placed on the first support portion 144, preventing it from rolling and slipping off. Since the first support portion 144 is in direct contact with the insulator 21, to avoid damaging the silicone rubber skirts on the surface of the insulator 21, the contact area between the first support portion 144 and the composite insulator 20 is made of nylon. Nylon has high mechanical strength, good toughness, a smooth surface, and a low coefficient of friction, and will not damage the surface of the composite insulator 20. In other embodiments, the contact area between the first support portion and the composite insulator can be made of other materials, as long as its surface is smooth and will not damage the surface of the composite insulator.

[0066] In this embodiment, there are two first support devices 140. Two first support devices 140 can more stably support the composite insulator 20, avoiding the instability that can occur when there is only one first support device 140 and it is not in the exact center of the composite insulator 20, which could lead to tilting and falling of the composite insulator 20. In other embodiments, the number of first support devices is not limited, as long as they can support the composite insulator and maintain its balance.

[0067] See Figure 1 , Figure 9 and Figure 10 Two second support devices 150 are spaced apart along the first direction F1 between the first support device 140 and the second heating device 130 to support the conductive rod 24, so that the second flange 23 is sleeved and fixed to the insulator 21. The second support device 150 includes a mounting part 151, a second support part 152, and a lifting part 153. The mounting part 151 is used to fix the second support device 150 to the main frame 110, that is, to fix the second support device 150 to the base 111. The second support part 152 is used to directly support the conductive rod 24. The lifting part 153 is located at the bottom of the second support part 152, and the lifting part 153 can move back and forth in the vertical direction to support the second support part 152 to move back and forth in the vertical direction, so that the second support device 150 can arbitrarily support the conductive rod 24 in the vertical direction.

[0068] The lifting unit 153 includes a top connecting plate 1531, a piston rod 1532, a third guide rod 1533, a cylinder mounting base 1534, and a first cylinder 1535. The top connecting plate 1531 is a flat plate structure. One end of the piston rod 1532 is fixedly connected to one side of the top connecting plate 1531, and the other end is inserted into the first cylinder 1535. Under the driving force of the first cylinder 1535, the piston rod 1532 can move back and forth vertically within the first cylinder 1535. A second support part 152 is fixedly connected to the other side of the top connecting plate 1531. The reciprocating movement of the piston rod 1532 in the vertical direction can drive the second support part 152 to move back and forth vertically, thereby enabling the second support device 150 to arbitrarily support the conductive rod 24 in the vertical direction.

[0069] The cylinder mounting base 1534 includes a first connecting portion 15341 and a second connecting portion 15342. The first connecting portion 15341 has a first mounting hole 15343, which abuts against the top of the first cylinder 1535, and the cylinder mounting base 1534 is fixedly connected to the first cylinder 1535 through the first mounting hole 15343. The first connecting portion 15341 also has a piston rod through hole 15344, through which the piston rod 1532 is inserted into the first cylinder 1535, and then moves back and forth vertically within the first cylinder 1535. There are two second connecting portions 15342, which are respectively fixedly connected to two opposite sides of the first connecting portion 15341, and the first cylinder 1535 is engaged between the two second connecting portions 15342. Two third guide rods 1533 are provided, one on each side of the piston rod 1532. The second connecting part 15342 has guide rod through holes 15345. One end of each third guide rod 1533 is fixedly connected to one side of the top connecting plate 1531, and the other end is inserted into the second connecting part 15342 through the guide rod through hole 15345. The third guide rods 1533 serve a guiding function, reducing the radial force on the piston rod 1532 and preventing radial displacement of the piston rod 1532.

[0070] The second connecting part 15342 is further provided with a plurality of second mounting holes 15346 on the side away from the first cylinder 1535. The mounting part 151 is fixedly connected to the cylinder mounting seat 1534 through the second mounting holes 15346. Specifically, the mounting part 151 includes a first mounting plate 1511 and a second mounting plate 1512. The first mounting plate 1511 and the second mounting plate 1512 are connected to each other to form an L-shaped structure. The side of the first mounting plate 1511 away from the second mounting plate 1512 abuts against the second connecting part 15342 and is fixedly connected to the second connecting part 15342 through the second mounting holes 15346. The second mounting plate 1512 is fixedly mounted on the base 111. A reinforcing member 1513 is also provided between the first mounting plate 1511 and the second mounting plate 1512. The reinforcing member 1513 connects the sides of the first mounting plate 1511 and the second mounting plate 1512 that are close to each other, making the structure of the second connecting part 15342 more stable, thereby making the second support device 150 stably set on the base 111.

[0071] Continue reading Figure 9 The second support part 152 includes a support base 1521 and a V-shaped roller support 1522. The support base 1521 is fixedly connected to the top connecting plate 1531 of the lifting part 153. The lifting part 153 can drive the second support part 152 to move back and forth in the vertical direction, thereby allowing the second support device 150 to arbitrarily support the conductive rod 24 in the vertical direction. The V-shaped roller support 1522 includes several evenly distributed rollers, which are fixedly connected to the support base 1521 and are arranged in a V-shape. This allows the conductive rod 24 to be held in place when placed on the second support part 152, preventing it from rolling and slipping. Since the second support part 152 is in direct contact with the conductive rod 24, the V-shaped roller support 1522 is made of nylon to avoid damaging the outer surface of the conductive rod 24. Nylon has high mechanical strength, good toughness, a smooth surface, and a low coefficient of friction, so it will not damage the surface of the composite insulator 20. In other embodiments, the contact area between the second support and the composite insulator can be made of other materials, as long as their surface is smooth and will not damage the outer surface of the conductive rod.

[0072] See Figure 1 and Figure 11The fixing plate 113 is a rectangular plate, which is fixedly connected to the base 111 in the vertical direction. Two fifth guide rails 1131 extending vertically are provided on the side of the fixing plate 113 near the first heating device 120, and the two fifth guide rails 1131 are spaced apart along the second direction F2. A reinforcing plate 1132 is slidably connected to the two fifth guide rails 1131 via a slider. A second cylinder 1133 is also connected to one side of the reinforcing plate 1132. Driven by the second cylinder 1133, the reinforcing plate 1132 can move vertically on the fifth guide rails 1131. The fixing plate 113 also has a through-hole 1134 located between the two fifth guide rails 1131, which is a through-hole channel. Its size is larger than that of the second flange 23, providing a through-hole channel for the second flange 23 and the conductive rod 24. When the second flange 23 is driven to pass through the through-hole 1134 and is located at the end of the insulator 21, the drive reinforcement plate 1132 moves vertically toward the second flange 23 and is secured to the second flange 23, further fixing the second flange 23. The second cylinder 1133 is fixed to the side of the fixing plate 113 near the first heating device 120, and is located on the side of one of the fifth guide rails 1131 away from the other. The fixing plate 113 has four third mounting holes 1135, and four first guide rods 114 are fixedly connected to the fixing plate 113 through the third mounting holes 1135.

[0073] Continue reading Figure 2 The binding machine 100 also includes an accordion cover 170, which is movably mounted on the two first guide rods 114 along the length of the main frame 110 and located below the glue receiving groove 1218. Specifically, the accordion cover 170 includes a telescopic part, which is accordion-shaped and composed of several connected pleats. The telescopic part can be extended and retracted along the length of the main frame 110. Placing the accordion cover 170 below the glue receiving groove 1218 can receive glue overflowing from the glue receiving groove 1218, preventing excessive glue from dripping onto the ground and being difficult to clean. In this embodiment, there is one accordion cover 170. In other embodiments, accordion covers may be provided below both glue receiving grooves; no specific limitation is made here.

[0074] The working process of the binding machine 100 is as follows: the first flange 22 is fixed to the first heating device 120, the second flange 23 connected to the conductive rod 24 is fixed to the second heating device 130, the insulator 21 is horizontally placed on the two first support devices 140, and the movement of the insulator 21 is controlled by the first moving bracket 142 and the second moving bracket 143 to make the first flange 22, the second flange 23, and the insulator 21 coaxial. The first pressure device 161 drives the first heating device 120 to move along the length direction of the main frame 110, and the second pressure device 162 drives the second heating device 130 to move along the length direction of the main frame 110. The heating device 130 moves along the length of the main frame 110, and at the same time adjusts the positioning conductive rod 24 through the positioning adjustment device 124 until the first flange 22 and the second flange 23 are respectively sleeved on both ends of the insulator 21 and clamp the insulator 21, so as to realize the matching installation of the first flange 22 and the second flange 23 with the insulator 21 and maintain the required adhesive pressure. The adhesive is injected through the injection holes of the first flange 22 and the second flange 23 respectively, and the first heating plate 1214 and the second heating plate 133 are heated to the required adhesive temperature, so that the adhesive is cured and the composite insulator 20 is glued.

[0075] The beneficial effects of this application are as follows: Unlike the prior art, the gluing machine of this application includes a main frame, a first heating device, a second heating device, a first support device, a second support device, and a pressure device. It can simultaneously glue the flanges at both ends of a hollow composite insulator with conductive rods, realizing a horizontal gluing process for composite insulators with conductive rods. Furthermore, by setting up a pressure device, the gluing pressure is kept stable, avoiding bias pressure. Moreover, dynamic pressure is applied throughout the gluing process, which can prevent flatness errors caused by heat deformation of the heating plate during the gluing process, effectively improving the product qualification rate. It is also easy to operate and has high production efficiency.
