Description

Technical Field

[0001] This invention relates to the field of assembly equipment technology, specifically to a planar transformer and its processing equipment. Background Technology

[0002] A planar transformer is a type of transformer manufactured using printed circuit board (PCB) technology or thin-layer processes. It boasts advantages such as small size, thinness, good heat dissipation, and low leakage inductance, and is widely used in power supplies, communications, and automotive electronics. A planar transformer mainly consists of core components such as an iron core, windings, insulating materials, core fixing components, and lead terminals. Its iron core is typically made of high-frequency power ferrite material in a small-sized E-type, RM-type, or toroidal structure to reduce high-frequency losses. The windings are achieved through spiral printed lines or folded copper foil on a multi-layer PCB. The windings are connected in series or parallel through vias to form a compact planar magnetic circuit. Insulating materials isolate the winding layers from the core, ensuring electrical safety. Core fixing components (such as tape or clips) tightly bond the core to the PCB to prevent vibration or displacement. Lead terminals provide external circuit connection interfaces; some designs utilize surface mount technology to save space.

[0003] Due to the intricate structure of the internal components of existing planar transformers, which need to be mounted on a relatively thin plane, high-precision robotic arms and control systems are typically required to perform precise assembly operations. This results in high equipment costs and the need for highly skilled operators, limiting their usability. Summary of the Invention

[0053] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0054] See Figures 1-10 This invention discloses a processing equipment for planar transformers and provides the following three technical solutions:

[0055] The first embodiment includes a feeding mechanism 1 and a stacking mechanism 2. The feeding mechanism 1 connects to the stacking mechanism 2 to transfer three parts of the planar transformer to the stacking mechanism 2 respectively. The stacking mechanism 2 then stacks and bonds the three parts together. The bottoms of both the feeding mechanism 1 and the stacking mechanism 2 are inclined to facilitate the sliding of the parts. The stacking mechanism 2 includes:

[0056] The second positioning seat 22 and the third positioning seat 23 are respectively hinged to the two sides of the first positioning seat 21. The first positioning seat 21, the second positioning seat 22 and the third positioning seat 23 are used to position the three parts of the planar transformer and to adsorb the three parts by negative pressure.

[0057] The connecting seat 24 is fixedly connected to the bottom of the first positioning seat 21 by screws, and also connects the second positioning seat 22 and the third positioning seat 23.

[0058] The fixed tray 25 is used to support the connecting seat 24 and allow the connecting seat 24 to slide left and right with a fixed range under external force. The three parts are promoted to slide onto the first positioning seat 21, the second positioning seat 22 and the third positioning seat 23 in a shaking manner. The fixed tray 25 is also provided with a centering structure to center the connecting seat 24 without external force.

[0059] The base 26 has its top four corners fixedly connected to the bottom of the fixed tray 25 via uprights;

[0060] The flipping mechanism 27 is installed on the top of the base 26 and is provided in two sets, which are used to drive the second positioning seat 22 and the third positioning seat 23 to flip so as to complete the sequential stacking of the three parts.

[0061] The air supply assembly 28 is connected to the first positioning seat 21, the second positioning seat 22 and the third positioning seat 23 through pipes. It is used to extract air from the first positioning seat 21, the second positioning seat 22 and the third positioning seat 23 during the stacking stage to adsorb the three parts, and to blow out the parts after the stacking is completed.

[0062] By positioning the three sheet-like parts of the planar transformer and stacking and bonding them by folding, the assembly accuracy is guaranteed, and there is no need to use precision and high-cost equipment such as robotic arms and high-precision control systems, which greatly reduces the cost and achieves the same effect. In addition, the air supply component 28 can use the suction and exhaust functions at the same time. It can hold the parts in place to prevent them from falling when flipping, and can also blow the parts out after stacking. The operation is simple and convenient.

[0063] The second embodiment differs from the first embodiment in that: the first positioning seat 21, the second positioning seat 22, and the third positioning seat 23 all include a box body 201, and the bottom of the box body 201 is covered with a bottom cover 202. The top of the box body 201 is provided with a recessed positioning groove 203. The width of the recessed positioning groove 203 on the side away from the feeding mechanism 1 corresponds to the size of the part to position the part. The width of the recessed positioning groove 203 on the side away from the feeding mechanism 1 is widened to receive the part. The two sections of the recessed positioning groove 203 are connected at an angle to guide the part. The three sides of the positioning section of the recessed positioning groove 203 are provided with negative pressure holes 204 that communicate with the inner cavity of the box body 201. The openings of the negative pressure holes 204 on the three sides of the first positioning seat 21 are also provided with air blowing holes 205.

[0064] The air supply assembly 28 includes a first negative pressure pipe 281 fixedly connected to the bottom of the first positioning seat 21, and a second negative pressure pipe 282 fixedly connected to the bottom of the second positioning seat 22 and the third positioning seat 23. The bottom end of the first negative pressure pipe 281 is sealed through to the bottom of the connecting seat 24 and is sealed with a four-way connector 283. Both ends of the four-way connector 283 are connected to the two second negative pressure pipes 282. The remaining end of the four-way connector 283 is connected to the main negative pressure pipe 284. The bottom of the air blowing hole 205 is connected to the air blowing pipe 286 through the connecting cover 206. The air blowing pipe 286 is sealed through to the bottom of the connecting seat 24.

[0065] The air supply assembly 28 also includes an air pump 287 and an electric five-way valve 288 fixedly connected to the top of the base 26. The electric five-way valve 288 includes a valve 2882 mounted on the top of the first servo motor 2881 fixedly connected to the top of the base 26. The valve plate 2883 inside the valve 2882 separates the five pipe heads into three and two. The air pump 287's inlet and outlet ends are respectively connected to the suction pipe 289 and the exhaust pipe 285. The suction pipe 289, the main negative pressure pipe 284, the blowing pipe 286, and the exhaust pipe 285 are sequentially connected to four of the pipe heads of the valve 2882. The remaining pipe head of the valve 2882 is equipped with an air filter head.

[0066] The bottom cover 202 of the first positioning seat 21 has a protruding ring 207 at the bottom corresponding to the passage of the air pipe 286. The top of the connecting seat 24 has a positioning groove 241 that matches the protruding ring 207. The inside of the connecting seat 24 has a large through groove 242 corresponding to the passage of the second negative pressure pipe 282. A U-shaped frame is fixedly connected to the bottom of the connecting seat 24 and to one side of the large through groove 242. A rotating cylinder 243 is rotatably mounted on the U-shaped frame. The second negative pressure pipe 282 overlaps the rotating cylinder 243 to reduce the friction when the second positioning seat 22 and the third positioning seat 23 flip and pull the second negative pressure pipe 282.

[0067] The centering structure includes upper magnets 244 fixedly connected to both sides of the bottom of the connecting seat 24, and lower magnets 251 fixedly connected to both sides of the top of the fixed tray 25. The upper magnets 244 and lower magnets 251 are positioned correspondingly, and the connecting seat 24 is centered relative to the fixed tray 25 by magnetic force.

[0068] Air pump 287 draws in air through suction pipe 289 and exhausts air through exhaust pipe 285. Suction pipe 289 draws air from electric five-way valve 288, and then uses main negative pressure pipe 284 to draw in air from four-way valve 283. Subsequently, the first negative pressure pipe 281 and the second negative pressure pipe 282 draw in air from the first positioning seat 21, the second positioning seat 22, and the third positioning seat 23, thus attracting the insulating substrate 3, coil 4, and magnetic core 5. After they are stacked, air pump 287 is stopped to eliminate the suction force, and then the second positioning seat 285 is controlled. 2 or the third positioning seat 23 rotates. After it has fully rotated, the air pump 287 is started until the stacking is completed. Then, the electric five-way valve 288 is switched to connect the suction pipe 289 with the main negative pressure pipe 284 and the filter head. This will draw out most of the outside air, making the suction force of the negative pressure hole 204 on the first positioning seat 21 small. The exhaust pipe 285 is connected with the blowing pipe 286, which will generate a blowing force from the blowing hole 205 to blow the parts to the left for collection. Then, the subsequent welding of the metal wire 6 and the assembly of the insulating shell 7 are carried out.

[0069] Figure 9 and Figure 10 The middle arrow indicates the direction of airflow.

[0070] The feeding mechanism 1 includes:

[0071] The three sets of feeding racks 11 are respectively connected to the three sets of sinking positioning grooves 203 on their left ends, and the left ends of the three sets of feeding racks 11 are all fixed on the fixed trays 25.

[0072] The bracket 12 is fixedly connected to the bottom of the feeding rack 11 to support the three sets of feeding racks 11.

[0073] The magnetic core 5, insulating substrate 3 and coil 4 are transported to three sets of loading racks 11 by conveyor belt or other equipment, and then slid into three sets of sinking positioning grooves 203. The surface of the insulating substrate 3 is coated with glue or double-sided tape is pasted on it.

[0074] The multiple pipelines of the air supply component 28 are connected and directionally controlled by a four-way valve 283 and an electric five-way valve 288, so that only one air pump 287 is needed to simultaneously realize negative pressure suction and air blowing discharge operations, and the two do not interfere with each other. The electric five-way valve 288 can be switched and started and stopped, making the control simple and convenient.

[0075] The third embodiment differs from the first embodiment mainly in that the flipping mechanism 27 includes:

[0076] The second servo motor 271 has a small toothed pulley 272 fixedly connected to its output end.

[0077] The large toothed pulley 273 is rotatably connected to the left side of the fixed tray 25, and the large toothed pulley 273 is driven by meshing with the small toothed pulley 272 through the gear belt 274;

[0078] The short shaft 275 is fixedly connected to the left side of the second positioning seat 22 and the third positioning seat 23;

[0079] The lever 276 has one end fixedly connected to the large toothed pulley 273, and the other end of the lever 276 is sleeved on the short shaft 275. The other end of the lever 276 has a groove 277 that is adapted to the short shaft 275.

[0080] After the second servo motor 271 drives the small toothed pulley 272 to rotate, it drives the large toothed pulley 273 to rotate through the gear belt 274, which in turn drives the large toothed pulley 273 and the lever 276 to rotate. The lever 276 pushes the short shaft 275 to make the second positioning seat 22 or the third positioning seat 23 flip, thereby causing the parts on it to flip and stack.

[0081] By driving the lever 276 to rotate via the second servo motor 271, the second positioning seat 22 and the third positioning seat 23 can be flipped sequentially. The operation is simple and convenient, and the degree of automation is high.

[0082] See Figures 11-13 The present invention discloses a planar transformer, including an insulating substrate 3, a coil 4 and a magnetic core 5. The coil 4 and the magnetic core 5 are both attached to the surface of the insulating substrate 3, and the magnetic core 5 is located inside the coil 4. Metal wires 6 are welded on both the coil 4 and the magnetic core 5. The insulating substrate 3 is transferred to the first positioning seat 21, and the magnetic core 5 and the coil 4 are transferred to the second positioning seat 22 and the third positioning seat 23, respectively.

[0083] The insulating substrate 3, coil 4 and magnetic core 5 are stacked together in two sets. The insulating substrate 3, coil 4 and magnetic core 5 are wrapped with an insulating shell 7. Electrodes 8 are embedded and fixed on both sides of the top of the insulating shell 7, and the metal wire 6 is electrically connected to the electrode 8.

[0084] Furthermore, all content not described in detail in this specification is existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used.
