Description

Technical Field

[0001] The present invention relates to the technical field of transformer production equipment, and further relates to a transformer nameplate glue dispensing device. Background Art

[0002] Instrument transformers are a special type of transformer used primarily for measurement and electrical protection in power systems. They use the principle of electromagnetic induction to convert high voltage or high current into low voltage or low current for use in measuring instruments, protective devices, and automatic control equipment.

[0003] A nameplate needs to be installed on the transformer. The nameplate usually comes in two forms: a PCB (Printed Circuit Board) plate with an RFID (Radio Frequency Identification) electronic chip or a metal nameplate.

[0004] Currently, there are two production methods for embedding nameplates on the current transformer body: one is to cast the transformer as a whole with the nameplate; the other is to cast the transformer without the nameplate and then use a secondary production method to paste the nameplate.

[0005] As customers' technical requirements for products increase, the production cycle for RFID nameplates has lengthened. Furthermore, during the one-piece casting process, individual substandard products are inevitable, impacting the overall batch management. Using a secondary adhesive method for nameplates results in inconsistent quality, reliability, and appearance consistency, making it difficult to guarantee, and also prolonging the production process. This method also requires pre-mixing the two adhesive materials before application. This requires a large amount of pre-mixed adhesive, making it difficult to precisely match the required amount, resulting in material waste or shortage.

[0006] For those skilled in the art, how to reduce the waste caused by colloid mixing is a technical problem that needs to be solved at present. Summary of the Invention

[0007] The core of the present invention is to provide a nameplate dispensing device for a mutual inductor, which can mix the colloid in the guide tube through a mixing rod. It does not require a motion structure, simplifies the stirring structure, and does not require the mixed colloid to be prepared in advance, thus avoiding insufficient or wasted dosage. The specific scheme is as follows:

[0008] A nameplate dispensing device for a mutual inductor comprises a guide tube and a mixing rod, wherein both ends of the guide tube are connected, and the feed end thereof is used for connecting to a multi-way connector;

[0009] The mixing rod is inserted into the guide tube, and the mixing rod includes a core rod and convex teeth. A plurality of convex teeth are radially protruding from the side wall of the core rod; and a plurality of convex teeth are arranged along the axial direction of the core rod.

[0010] The feed end of the guide tube is used to input colloids of at least two different materials. The colloids are mixed and stirred when flowing through the convex teeth, and are output from the discharge end of the guide tube and coated in the glue dispensing groove of the mutual inductor.

[0011] Optionally, the protruding teeth are provided with multiple layers along the axial direction, and the projections of the protruding teeth of two adjacent layers along the axial direction are staggered with each other.

[0012] Optionally, two protruding teeth are provided in each layer, and the two protruding teeth in the same layer are centrally symmetrically distributed or axially symmetrically distributed.

[0013] Optionally, the core rod is in the shape of a rectangular parallelepiped rod;

[0014] The convex teeth include a first connecting plate and a second connecting plate fixed at a right angle, the first connecting plate is parallel to the axis of the core rod, the second connecting plate forms an angle with the axis of the core rod, and the second connecting plate forms an inclined surface toward the discharge end.

[0015] Optionally, the second connecting plate is in the shape of a right triangle;

[0016] The included angle between the second connecting plate and the core rod near the discharge end is in the range of 45°-60°.

[0017] Optionally, a connecting block is fixedly provided on the top end of the core rod, and a connecting hole is provided on the connecting block, and the connecting hole is used to connect with the multi-way connector.

[0018] Optionally, an enlarged portion is provided at the feed end of the guide tube, and an inner wall of the enlarged portion is provided with an internal thread for threaded connection with the multi-way connector;

[0019] A contraction portion is provided at the discharge end of the guide tube.

[0020] Optionally, at least three support columns are provided in the glue dispensing groove of the mutual inductor, and the support columns contact the bottom surface of the support nameplate and avoid the radio frequency tag on the bottom surface of the nameplate.

[0021] Optionally, a carrier for carrying the mutual inductor is further included, and at least two step blocks are respectively protruded upward at the four top corners of the upper surface of the carrier, for supporting and circumferentially limiting the mutual inductors of at least two different specifications.

[0022] Optionally, a first chamfer is provided on the edge of the step block;

[0023] And / or, a limiting groove is provided in the central area of ​​the upper surface of the carrier, and a second chamfer is provided on the edge of the limiting groove.

[0024] The present invention provides a nameplate dispensing device for a mutual inductor. Both ends of a guide tube are through-connected, and a feed end thereof is used for docking a multi-way joint. Colloids of different materials are input from the joint to the feed end of the guide tube. The colloid moves from the feed end to the discharge end and contacts a mixing rod during the movement. The mixing rod is provided with a plurality of convex teeth, and the colloid flows through the gap between the convex teeth and the guide tube. When the colloid flows through the convex teeth, it is mixed and stirred, so that different colloids are mixed evenly. The mixed colloid is output from the discharge end of the guide tube, coated in the dispensing groove of the mutual inductor, and can be bonded to the nameplate. The present invention does not require active stirring for mixing of the colloid, and the mixing is passively completed when passing through the mixing rod. When glue supply is not needed, the feeding to the feed end can be directly stopped. There is no need to mix a large amount of colloid in advance, which reduces the waste caused by excessive colloid mixing. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] In order to enable those skilled in the art to better understand the technical solution of the present invention, the transformer nameplate dispensing device of the present invention will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0042] The invention provides a nameplate dispensing device for transformers, which can be used in transformer production equipment during the secondary nameplate pasting process. The colloid targeted by the invention is a mixed glue that exerts adhesive effect after mixing different materials. The adhesive can only be fully exerted after being fully mixed.

[0043] Combine Figure 1 、 Figure 2 As shown, the present invention provides a device for dispensing glue on transformer nameplates, comprising a guide tube 10 and a mixing rod 20. The guide tube 10 is a hollow pipe with two through-holes, one for the feed end and the other for the discharge end. The feed end of the guide tube 10 is connected to a multi-way connector (not shown in the figure). When mixing two colloids, the multi-way connector can be a tee connector; when mixing three colloids, the multi-way connector can be a four-way connector.

[0044] One of the interfaces of the multi-way connector is connected to the feed end of the guide tube 10, and each of the other interfaces is connected to a glue supply pipeline. Each of the other interfaces can input a type of colloid. When the number of types of colloids to be mixed is N, the multi-way connector can use N+1 interfaces.

[0045] The guide tube 10 can be a cylindrical structure with a circular cross section; the mixing rod 20 is inserted into the guide tube 10, and the length extension direction of the mixing rod 20 is the same as the length extension direction of the guide tube 10. The function of the mixing rod 20 is to mix the colloid entering the guide tube 10. Figure 3A 、 Figure 3B and Figure 3C As shown, the mixing rod 20 includes a core rod 210 and a convex tooth 220. The core rod 210 is a slender rod-like structure. The length extension direction of the mixing rod 20 is axial, and the direction perpendicular to the axial direction is radial. The distinction between axial and radial does not mean that the core rod 210 can only be cylindrical, and can also have other cross-sectional shapes.

[0046] The sidewall of the core rod 210 is radially protruding with a plurality of teeth 220. Each individual tooth 220 cannot form a complete circle around the core rod 210, otherwise the colloid cannot flow through. Multiple teeth 220 are arranged along the axial direction of the core rod 210. During the axial flow of the colloid along the core rod 210, the colloid will continuously contact the teeth 220. Because the teeth 220 are block-shaped structures that block the colloid, the colloid is blocked by the teeth 220 and separated into two streams, which continue to flow axially from the left and right sides of the teeth 220. All the teeth 220 distributed around the periphery of the core rod 210 cannot be located on the same straight line, but need to be staggered in the circumferential direction. During the axial flow of the colloid, the colloid will be blocked and divided by the teeth 220 that are not in the same direction. The teeth 220 will cut, stir and mix the colloid, thereby achieving stirring and mixing of colloids of different materials.

[0047] During use, at least two different colloids are fed into the feed end of the guide tube 10. The colloids are not pre-mixed and remain independent of each other. The different colloids enter the multi-way connector and initially contact the feed end of the guide tube 10. As the colloids flow axially, they are mixed and stirred as they pass through the ridges 220. Each ridge 220 divides the colloid, continuously stirring the colloids. As the colloids flow in and out, they are gradually and evenly mixed.

[0048] The evenly mixed colloid is discharged from the discharge end of the guide tube 10 and applied to the glue dispensing groove 401 of the mutual inductor 40. After the glue is applied, the nameplate 50 is placed and adhered to the mutual inductor 40 to achieve the bonding and fixation of the nameplate 50. The upper surface of the nameplate 50 is exposed and marked with various information of the mutual inductor.

[0049] Combine Figure 3A 、 Figure 3B As shown, the convex teeth 220 are provided with multiple layers along the axial direction of the core rod 210. The axial position of the convex teeth 220 of each layer is different. The axial projections of the two adjacent layers of convex teeth 220 are staggered and do not overlap, ensuring that the colloid can be cut and stirred when it flows to each layer in turn, so as to form a more sufficient stirring and mixing of the colloid.

[0050] Combine Figure 3A 、 Figure 3B 、 Figure 3CAs shown, two protruding teeth 220 are provided in each layer. The two protruding teeth 220 in the same layer are located in the same axial position on the core rod 210. The two protruding teeth 220 in the same layer are arranged in a centrally symmetrical or axially symmetrical distribution. When the centrally symmetrical distribution is adopted, the axis of symmetry of the two protruding teeth 220 is the central axis of the core rod 210. When the axially symmetrical distribution is adopted, the symmetry planes of the two protruding teeth 220 are located on the central axis. The symmetry planes of the protruding teeth 220 in two adjacent layers are not coplanar. The symmetry planes of the protruding teeth 220 in two adjacent layers can be at an angle of 90 degrees, 60 degrees, or the like. For protruding teeth 220 that are separated by two or more layers, the symmetry planes can be coplanar.

[0051] Combine Figure 3A 、 Figure 3B 、 Figure 3C As shown, the mandrel 210 used in the present invention is in the shape of a rectangular parallelepiped rod, but may also be cylindrical. The protruding teeth 220 include a first connecting plate 221 and a second connecting plate 222 fixed at a right angle. The first connecting plate 221 and the second connecting plate 222 are plate-like structures of a certain thickness, and are arranged perpendicular to each other. The first connecting plate 221 and the second connecting plate 222 are both fixed to the mandrel 210.

[0052] Combine Figure 3C As shown, the surface of the first connecting plate 221 is parallel to the axis of the core rod 210, and the second connecting plate 222 forms an angle with the axis of the core rod 210; since the first connecting plate 221 is parallel to the axis of the core rod 210, the first connecting plate 221 mainly provides fixed support; the second connecting plate 222 forms an inclined surface toward the discharge end, and the position of the second connecting plate 222 close to the core rod 210 is closer to the feed end, and the position of the second connecting plate 222 away from the core rod 210 is closer to the discharge end. The second connecting plate 222 forms an inclined surface to guide the flow of the colloid and to block and divide the colloid.

[0053] Combine Figure 3A 、 Figure 3B As shown, in a specific embodiment, the second connecting plate 222 of the present invention is in the shape of a right triangle, and the second connecting plate 222 gradually narrows toward the direction close to the guide tube 10, forming a structure with varying dimensions.

[0054] Specifically, the angle between the second connecting plate 222 and the core rod 210 near the discharge end ranges from 45° to 60°, inclusive. The section from the connection point between the second connecting plate 222 and the core rod 210 to the discharge end forms an acute angle with the second connecting plate 222. By varying the angle, the effect of colloid segmentation and guidance can be varied.

[0055] Combine Figure 3A 、 Figure 3BAs shown, the present invention securely mounts a connecting block 230 at the top end of the mandrel 210. The cross-sectional area of ​​the connecting block 230, perpendicular to the axis, is larger than that of the mandrel 210. The connecting block 230 can be plate-shaped or solid. Connecting holes 231 are provided on the connecting block 230. These holes are through-holes at both ends and are used to connect to a multi-way connector. Connecting pins are installed on the multi-way connector and pass through the connecting holes 231 to support the mixing rod 20. In this structure, the mixing rod 20 is merely inserted into the lumen of the guide tube 10 and is not fixed relative to the guide tube 10. The mixing rod 20 is mounted on the multi-way connector.

[0056] Combine Figure 1 、 Figure 2 As shown, an expansion portion 110 is provided at the feed end of the guide tube 10. The radial dimension of the expansion portion 110 is larger than the radial dimension of the guide tube 10. The expansion portion 110 is a cylindrical thin shell. The inner wall of the expansion portion 110 is provided with an internal thread for threaded connection with the multi-way connector. The expansion portion 110 is directly fixed to the multi-way connector.

[0057] The discharge end of the guide tube 10 is provided with a contraction portion 120 to collect the colloid before discharge. Figure 3C As shown, the contraction portion 120 is composed of a plurality of stepped tubular structures that contract step by step, forming a step-by-step contraction and convergence effect. In addition, the contraction portion 120 can also adopt a conical cylindrical structure, and these specific implementation forms should be included in the protection scope of the present invention.

[0058] Combine Figure 4 As shown, the local structure of the mutual inductor 40 is shown. At least three support columns 402 are set in the glue dispensing groove 401 of the mutual inductor 40. The three points determine a plane to support the nameplate 50. Figure 3C There are four support columns 402, one at each of the four corners near the dispensing slot 401. The top points of all the support columns 402 should be on the same plane to ensure stable support of the nameplate 50.

[0059] Combine Figure 7 As shown, a radio frequency tag 501 is mounted on the bottom of the nameplate 50. The radio frequency tag 501 is pre-encapsulated with curing glue to form a protrusion on the bottom of the nameplate 50. The radio frequency tag 501 is pre-set with the information of the mutual inductor, and the information of the mutual inductor can be sensed and identified through the radio frequency tag 501.

[0060] The support column 402 contacts the bottom surface of the nameplate 50 and avoids the RFID tag 501 on the bottom surface of the nameplate 50. The support column 402 cannot contact the RFID tag 501, ensuring that the nameplate 50 contacts the support column 402 for stable support.

[0061] Because support columns 402 are pre-installed in the glue dispensing slot 401 of the transformer 40, when the nameplate 50 is placed, there is a gap between the bottom surface of the nameplate 50 and the bottom surface of the glue dispensing slot 401. This gap can accommodate the glue, allowing the glue to be evenly distributed in the glue dispensing slot 401. Without support columns 402, the nameplate 50 would be lifted up by the glue, and the glue thickness in different positions might be uneven, resulting in an uneven nameplate and affecting the appearance quality. When injecting glue, the glue only needs to be injected to a height slightly above the support columns 402 to prevent excessive glue from flowing sideways onto the upper surface of the nameplate 50.

[0062] The transformer nameplate dispensing device of the present invention further includes a carrier 60 for carrying the transformer 40, Figure 5 、 Figure 6 As shown, the carrier 60 is substantially rectangular, and ear plates for fixing are fixed in the middle of two long sides.

[0063] At least two step blocks 610 are provided at the four top corners of the upper surface of the carrier 60, protruding upwards. The step blocks 610 are higher than the upper surface of the carrier 60 to form convex blocks. Figure 5 Three step blocks 610 are respectively provided at each vertex corner. The step blocks 610 at the four vertex corners are used in conjunction with each other to support and circumferentially limit at least two mutual inductors 40 of different specifications.

[0064] Combine Figure 5 As shown, when a transformer 40 of a certain specification is placed on the upper surface of the carrier 60, the upper surface of the carrier 60 supports the transformer 40, and the lowest step block 610 forms a circumferential limit for the transformer 40; when a transformer 40 of a certain specification is placed on the upper surface of the lowest step block 610, the upper surface of the lowest step block 610 supports the transformer 40, and the second-level step block 610 forms a circumferential limit for the transformer 40; when a transformer 40 of a certain specification is placed on the upper surface of the second-level step block 610, the upper surface of the second-level step block 610 supports the transformer 40, and the third-level step block 610 forms a circumferential limit for the transformer 40.

[0065] The shapes of the step blocks 610 at each level can be set according to the bottom size of the mutual inductor. The step blocks 610 at the four corners are in an "L"-shaped right-angle shape, thereby limiting the mutual inductor in the length and width directions.

[0066] By providing the step blocks 610 , one carrier 60 can accommodate a variety of mutual inductors 40 of different specifications, thereby improving the utilization rate of the carrier.

[0067] Combine Figure 5 As shown, in one embodiment, a first chamfer 611 is provided on the edge of each step block 610. The first chamfer 611 forms an inclined surface, which can serve as a guide when placing the mutual inductor and reduce the occurrence of the mutual inductor being stuck.

[0068] In one embodiment, a limiting groove 620 is provided in the center area of ​​the upper surface of the carrier 60. The limiting groove 620 is concave downwards, and a second chamfer 621 is provided at the edge of the limiting groove 620. A smaller mutual inductor can be placed in the limiting groove 620. Figure 5 In the displayed structure, four transformers of different specifications and sizes can be placed.

[0069] Multiple carriers are placed on a circular guide rail conveyor line, onto which the transformers to be poured are placed. Nameplates are loaded using an automatic loading mechanism. A barcode scanner automatically scans the transformers and performs an RFID check on the nameplates. The collected data is then bound and stored in the equipment database. The equipment automatically injects glue at the labeling area. The matching nameplates are automatically attached to the workpieces and then heated and cured. The equipment automatically grabs the labeled transformers, places them in a temporary storage line, and transports them to the next process. By designing carriers that can hold various types of transformers, the system enables automatic quantitative dispensing of nameplates, as well as automatic RFID and barcode identification and binding.

[0070] Manual loading: Transformer products to be OEMed are brought to a location near the production line and manually placed into the product carriers on a circular rail conveyor. After unloading, the circular rail conveyor automatically transports the products to the code scanning and matching station. The carriers are made of plastic or nylon to prevent friction between the products and the fixtures during operation, which could cause damage to the product. Each carrier has a reserved area for nameplate storage, which is used for subsequent product code scanning and matching.

[0071] Nameplate feeding mechanism: This mechanism primarily consists of a nameplate placement module (which uses a vacuum mechanism to grab nameplates), a nameplate loading conveyor, radio frequency inspection equipment, and a nameplate feeding mechanism. A pallet containing a certain number of nameplates is manually placed onto the nameplate conveyor. The nameplate placement module extracts the nameplates and places them at the radio frequency inspection station for inspection. After inspection, the nameplates are fed to the island rail conveyor, where they are transported simultaneously with the products at the manual loading station.

[0072] Scanning and matching mechanism: This station is mainly composed of a scanning gun; the scanning gun reads the product QR code of the circular rail conveyor and pairs and binds it with the information of the nameplate radio frequency station, and sends it to the computer storage system.

[0073] Glue injection mechanism: This mechanism is primarily composed of a glue dispenser and a control system. Once the product nameplate and product code are paired, the circular rail conveyor moves the product to the glue injection station. The glue retaining mechanism moves out of the way, and the glue dispenser injects glue to the product nameplate location. After glue injection, the glue retaining mechanism returns to its original position.

[0074] Nameplate assembly mechanism: It mainly consists of a vacuum mechanism and a shift mechanism. After the product is injected with glue and moved to this station, the nameplate is sucked by the vacuum and assembled with the product through the shift mechanism.

[0075] Scan code detection: Use a barcode scanner to read the assembled nameplate for detection.

[0076] Nameplate drying and curing: This system primarily consists of an off-line fixture and an electric heating lamp (the temperature of the lamp is adjustable and mounted on the off-line conveyor). The off-line fixture picks up the scanned and inspected products and places them onto the off-line conveyor for a drying and curing station. This station heats the nameplates after assembly to help the adhesive cure quickly.

[0077] Off-line mechanism: It mainly consists of an off-line conveyor and a full-material sensing device. Products with completed nameplate assembly are transported to the full-material sensing device via the off-line conveyor.

[0078] This invention improves the quality, reliability, and consistency of nameplates on transformers, preventing cracking caused by shrinkage around the nameplates. It also reduces the inefficient transfer of products during the production process, which is time-consuming and labor-intensive. Automated processing increases production efficiency by approximately two times and reduces production costs by approximately 75%. RFID nameplates are protected from damage during the production process, ensuring smoother production organization.

[0079] The above description of the disclosed embodiments is intended to enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
