[0002] Currently, the assembly process in the middle stage of transformer production (core installation, coating, testing, dispensing, and marking) largely relies on manual labor or semi-automated equipment, resulting in the following technical problems: Core installation requires manual positioning and pushing, leading to high core assembly costs per transformer; Coating and dispensing processes require manual assistance for material loading and changing, which is difficult to meet the needs of mass production; Manual core positioning is prone to misalignment, causing abnormal transformer characteristics; Manual dispensing is prone to glue dot misalignment and uneven thickness, resulting in a high defect rate; Unstable tape tension control during coating can easily lead to loose winding or breakage; Core tray replacement and tape replenishment require machine shutdown; Manual handling of workpieces is required between processes, and characteristic testing is performed on specific testing equipment, requiring the workpieces to be returned to the production line after testing, resulting in long connection times; The marking process is manual, resulting in poor marking clarity and positional deviations, failing to meet product traceability requirements.

[0013] Compared with existing technologies, the advantages of the automatic assembly line for the middle section of the high-frequency transformer of this invention are as follows: This invention improves production efficiency through the fully automated design of the entire process, including magnetic core installation, coating, testing, dispensing, marking, and unloading.

[0014] From core loading, sorting, angle adjustment, and pushing installation to transformer transfer, positioning, and finished product output, the entire process requires no manual intervention, solving the problems of low efficiency and reliance on manual labor in traditional manual and semi-automated equipment; the front and rear dual modules operate synchronously, core preparation and transformer transfer are carried out in parallel, and empty material trays are automatically recycled and new material trays are automatically replenished, meeting the needs of mass production.

[0015] Adopting a dual-station alternating operation mode, the right station feeds material simultaneously while the left station is winding, and the next round of winding begins immediately after the station switch, with no downtime. Compared to single-station equipment, the coating efficiency is nearly doubled in the same amount of time, adapting to the pace of large-scale production lines. Only one tape turntable supplies adhesive to both stations, eliminating the need for additional tape supply components, reducing equipment costs and space occupation. At the same time, during station switching, the tape naturally stretches as the workpiece moves, completing the initial bonding of the new workpiece, avoiding tape waste, reducing consumable costs, and requiring no manual intervention throughout the process, making it suitable for large-scale production.

[0016] By using dual-fixture rotation and parallel loading / unloading with dispensing, the idle time of traditional single-station equipment is eliminated, improving equipment utilization and significantly reducing the dispensing time per transformer. The fixture placement slot and automated dispensing nozzle replace manual positioning, minimizing glue dot offset and reducing the difference in glue layer thickness on both sides, thus greatly reducing the defect rate. From loading / unloading to dispensing and unloading, no manual intervention is required, allowing direct integration into the transformer production line, reducing bumps and damage caused by manual handling, and minimizing human interference in the production process.

[0017] The testing station is linked with the coating and dispensing components through a transfer module. The testing process runs in parallel with the preceding and following processes, ensuring the main line operates without downtime and maintaining production speed.

[0018] Transfer module four transfers the dispensing transformer to the marking station. After marking is completed, transfer module five directly transfers it to the discharge tray without manual assistance, greatly reducing the marking time per unit. Attached Figure Description

[0020] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Unless otherwise explicitly specified and limited, the terms "installed," "connected," and "linked" should be interpreted broadly; for example, they can refer to a fixed connection or a detachable connection. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0021] The following describes the embodiments and appendices. Figures 1-12 The technical solution of the present invention will be further described below.

[0022] Example 1 An automated assembly line for the mid-section of a high-frequency transformer includes: a magnetic core mounting assembly 1, a transformer coating assembly 2, a characteristic testing assembly 4, a transformer adhesive dispensing assembly 3, a laser marking assembly 5, and a discharge tray 6 arranged sequentially. The magnetic core mounting assembly 1 assembles two sets of magnetic cores onto the transformer; the transformer coating assembly 2 secures the two sets of magnetic cores on the transformer by wrapping them with adhesive tape; the characteristic testing assembly 4 performs characteristic tests on the coated transformer; the transformer adhesive dispensing assembly 3 applies adhesive to the top of the transformer after testing; the laser marking assembly 5 marks the coated transformer; and the discharge tray 6 collects the marked transformer.

[0023] As a further preferred embodiment, the magnetic core mounting assembly 1 includes a front frame 101, a transformer conveying channel 102, an assembly platform 103, a front magnetic core mounting module 104, and a rear magnetic core mounting module 105. The transformer conveying channel 102 is disposed on the front frame 101, the assembly platform 103 is disposed on the front frame 101 and located in the middle of the transformer conveying channel 102, and the front magnetic core mounting module 104 and the rear magnetic core mounting module 105 are disposed on the front frame 101 and located on both sides of the assembly platform 103. Each of the rear magnetic core mounting modules 105 includes a magnetic core disk 106, a transfer module 107, a conveying platform 108, and a pushing module 109. The transfer module 107 transfers the magnetic core assembly in the magnetic core disk 106 to the conveying platform 108. The rear pushing module 109 and the front pushing module 109 sequentially push the magnetic cores on their respective conveying platforms 108 into the transformer on the assembly table 103. The front frame 101 is equipped with a transfer and discharge module 110, which sends the transformer with the magnetic core installed into the rear section of the transformer conveying channel 102.

[0024] The above structure enables the entire process of magnetic core feeding, transformer transfer, dual magnetic core installation, and finished product output without manual intervention, significantly improving efficiency compared to traditional manual installation. Through the coordination of the assembly table positioning, magnetic core sorting mechanism, and dedicated push module, the docking deviation between the magnetic core and the transformer coil is small, reducing the product defect rate and solving the problem of inaccurate positioning during manual installation. The front and rear dual magnetic core installation modules operate synchronously, allowing magnetic core preparation and transformer transfer to proceed in parallel without waiting time, meeting the needs of large-scale continuous production and reducing equipment idle time.

[0025] As a further preferred embodiment, the transfer module 107 includes a linear track assembly 1071, a lifting assembly 1072, and a magnetic core adsorption assembly 1073. The linear track assembly 1071 is installed on the upper end of the front frame 101. The upper end of the lifting assembly 1072 is installed on the linear track assembly 1071. The magnetic core adsorption assembly 1073 is installed on the lower end of the lifting assembly 1072. The magnetic core adsorption assembly 1073 includes a magnetic core vertical drive assembly 10731, a magnetic adsorption head 10732, and a pressure plate 10733. The magnetic core vertical drive assembly 10731 is installed on one side of the lower end of the lifting assembly 1072. The pressure plate 10733 is installed on the lower end of the magnetic core vertical drive assembly 10731. The magnetic adsorption head 10732 is installed on the lower end of the magnetic core vertical drive assembly 10731 and is located on the upper end of the pressure plate 10733. The linear track assembly 1071 provides a horizontal movement trajectory, driving the lifting assembly 1072 and the magnetic core adsorption assembly 1073 below to transfer between the magnetic core disk 106 and the conveyor platform 108; the magnetic core vertical drive assembly 10731 drives the magnetic adsorption head 10732 and the pressure plate 10733 to move down synchronously. The pressure plate 10733 first contacts the surface of the magnetic core to form a stable support, and the magnetic adsorption head 10732 generates magnetic force to adsorb the magnetic core through the pressure plate 10733; after being transferred to the conveyor platform 108, the magnetic adsorption head 10732 first moves up, and the magnetic force weakens as the distance increases. The pressure plate 10733 remains in a downward pressing state until the magnetic core is completely placed on the conveyor belt, and then moves up and resets as a whole with the magnetic core adsorption assembly 1073. The pressure plate 10733 prevents the magnetic adsorption head 10732 from directly contacting the magnetic core, thus preventing scratches on the surface of the magnetic core. At the same time, it ensures that the magnetic core is subjected to uniform force during adsorption, avoiding tilting or deformation. The magnetic adsorption head 10732 and the pressure plate 10733 work together to ensure that the magnetic core does not fall off or shift during the transfer process, thus improving the transfer accuracy.

[0026] The transfer module 107 further includes a tray gripping component 1074, which is installed at the lower end of the lifting component 1072. The tray gripping component 1074 includes a tray vertical drive component 10741 and a tray gripper 10742. The tray vertical drive component 10741 is installed on the other side of the lower end of the lifting component 1072, and the tray gripper 10742 is installed at the lower end of the tray vertical drive component 10741. When the magnetic cores in the core tray 106 are used up, the lifting assembly 1072 moves the tray gripping assembly above the empty tray; the tray vertical drive assembly 10741 drives the tray gripper 10742 downward, and the gripper closes to clamp the edge of the empty tray; then the lifting assembly 1072 moves the empty tray above the empty tray shelf 1063, and the gripper opens to place the empty tray on the shelf; at the same time, the chassis lifting assembly 1062 drives the new magnetic core tray on the shelf 1061 to move upward and replace the original magnetic core tray, completing the empty tray retrieval and new tray replacement. The automatic retrieval of the empty tray and the docking of the new tray eliminates the need for manual handling and reduces downtime for changing materials.

[0027] The conveying platform 108 of the front magnetic core mounting module 104 and the rear magnetic core mounting module 105 includes a magnetic core assembly conveyor belt 1081, a side drive pusher plate 1082, and a rear drive pusher plate 1083. The side drive pusher plate 1082 is located on the right side of the magnetic core assembly conveyor belt 1081 to push the magnetic core assembly into a neat arrangement. The rear drive pusher plate 1083 is located on the rear side of the magnetic core assembly conveyor belt 1081 to push the neatly arranged magnetic core assembly to the front end of the magnetic core assembly conveyor belt 1081. After the magnetic core adsorption assembly transfers the magnetic cores to the magnetic core assembly conveyor belt 1081, the conveyor belt drives the magnetic cores towards the installation station. First, the side drive push plate 1082 pushes horizontally from the right side of the magnetic core assembly, pushing the laterally arranged magnetic cores towards the left reference plane, aligning the magnetic cores in the lateral direction and eliminating lateral deviation during adsorption and transfer. Subsequently, the rear drive push plate 1083 pushes forward from the rear side of the magnetic core assembly, pushing the longitudinally arranged magnetic cores towards the installation station at the front end of the conveyor belt, aligning the magnetic cores in the longitudinal direction and forming a neat magnetic core assembly. Through the bidirectional alignment of side and rear pushes, the lateral and longitudinal alignment deviations of the magnetic core assembly are reduced.

[0028] The pushing module 109 of the front magnetic core mounting module 104 includes a magnetic core gripper 1091, a first front push cylinder 1092, and a tilting cylinder 1093. The magnetic core gripper 1091 is mounted on the output end of the tilting cylinder 1093, and the tilting cylinder 1093 is mounted on the output end of the first front push cylinder 1092. The magnetic core gripper 1091 tilts to push the front magnetic core into the transformer for installation. The pushing module 109 of the rear magnetic core mounting module 105 includes a front push rod 1094 and a second front push cylinder 1095. 1094 is installed at the output end of the front push cylinder 1095. The front push rod 1094 pushes the rear magnetic core into the transformer. The output end of the conveying platform 108 of the front magnetic core mounting module 104 is provided with a magnetic core baffle 1084. The lower end of the magnetic core baffle 1084 is provided with a magnetic core baffle drive assembly 1085. The output end of the conveying platform 108 of the rear magnetic core mounting module 105 is an arc-shaped material guide channel 1086. The arc-shaped material guide channel 1086 is provided with two sets of symmetrical arc-shaped limiting blocks 1087. When the rear magnetic core moves down to the push position via the arc-shaped material guide channel 1086, the second front push cylinder 1095 drives the front push rod 1094 to push it forward horizontally. The front end of the push rod fits against the rear side of the magnetic core, pushing the magnetic core along the straight channel into the rear mounting position of the transformer. After the push is completed, the second front push cylinder 1095 drives the push rod to reset, waiting for the next magnetic core. The direct push structure is simple and reliable, and the pushing speed is fast.

[0029] The magnetic core gripper 1091 is initially in the open state. The flipping cylinder 1093 drives the gripper to flip backward 90°, aligning it with the front magnetic core at the front end of the conveyor platform. After the gripper closes and clamps the magnetic core, the magnetic core baffle 1084 moves upward to release the obstruction. The flipping cylinder 1093 then drives the gripper to flip forward 90°. After the magnetic core gripper 1091 releases the magnetic core, it re-clamps the magnetic core, adjusting it to match the front mounting port of the transformer and align it with the rear magnetic core, thus improving installation accuracy. Subsequently, the forward pushing cylinder 1092 pushes the gripper forward, pushing the magnetic core into the front mounting position of the transformer, and the gripper opens and resets.

[0030] When the front magnetic core is waiting to be loaded at the front end of the conveyor platform, the magnetic core baffle drive assembly 1085 drives the magnetic core baffle 1084 to move downward, blocking the front end of the foremost magnetic core and preventing it from falling due to the inertia or vibration of the conveyor belt. When the magnetic core gripper 1091 needs to grip the magnetic core, the baffle drive assembly drives the baffle to move upward, releasing the obstruction. After the gripper completes the gripping, the baffle moves downward again to reset. After the rear magnetic core enters the arc-shaped guide channel 1086 from the front end of the conveyor platform, it slowly moves downward along the arc-shaped trajectory. Two sets of symmetrical arc-shaped limiting blocks 1087 in the channel respectively abut from both sides of the magnetic core, limiting the magnetic core's lateral displacement.

[0031] A transfer and feeding module 111 is installed on the front frame 101. The transfer and feeding module 111 is located on the left side of the assembly table 103. The transfer and feeding module 111 includes a material transfer rod 1111, a vertical material transfer drive assembly 1112, a horizontal material transfer drive assembly 1113, a circular rubber-coated pressure head 1114, a connecting rod assembly 1115, a stop block 1116, a stop drive assembly 1117, an upper pressure head 1118, and a pressure head drive assembly 1119. The material transfer rod 1111 is located in front of the vertical material transfer drive assembly 1112, and the rear of the vertical material transfer drive assembly 1112 is connected to the horizontal material transfer drive assembly 1113. Under the driving action, the material transfer rod 1111 is inserted into the transformer and moved to the assembly table 103. The stop block 1116 is located on the transformer. Between the conveyor channel 102 and the assembly table 103, the stop block 1116 is located on the front side of the stop drive assembly 1117, and the stop block 1116 moves back and forth under the drive. The circular rubber-coating pressure head 1114 is located at the upper end of the stop block 1116 and at the output end of the connecting rod assembly 1115. The material transfer rod 1111 is inserted into the transformer under the drive. The upper pressure head 1118 is located at the upper end of the assembly table 103 and at the output end of the pressure head drive assembly 1119. The bottom of the magnetic core disk 106 is provided with a shelf 1061, and the bottom of the shelf 1061 is provided with a chassis lifting assembly 1062. An empty material tray shelf 1063 is provided on one side of the magnetic core disk 106 and on the front frame 101.

[0032] The stop block 1116 extends under the action of the stop drive assembly 1117, blocking the transformer in the conveying channel; the transfer rod 1111 moves down and inserts into the inner hole of the transformer under the action of the vertical transfer drive assembly 1112, and the horizontal transfer drive assembly 1113 drives the rod and the transformer to move towards the assembly table. During the process, the transformer pushes the circular rubber-coated pressure head 1114 upward to prevent the tape head from being pulled open; after the transformer arrives at the assembly table, the upper pressure head 1118 moves down under the action of the pressure head drive assembly 1119 to press the top of the transformer and prevent the transformer from shifting when installing the magnetic core; at the same time, the stop block 1116 resets to block the next transformer, and the circular rubber-coated pressure head 1114 falls back under the action of gravity and the connecting rod assembly 1115 to press the tape head of the next transformer again, and the transfer rod 1111 resets.

[0033] The material transfer rod is inserted into the inner hole of the transformer for transfer, avoiding contact with the coil and preventing coil damage; the circular rubber-coated pressure head 1114 effectively fixes the tape head, solving the problem of tape opening during transformer transfer; the cooperation between the upper pressure head and the stop block enables precise positioning of the transformer on the assembly table.

[0034] The shelf 1061 is used to stack and store multiple new magnetic core trays. The chassis lifting assembly 1062 automatically adjusts the height of the shelf according to the remaining magnetic core in the magnetic core tray: when the magnetic core in the top magnetic core tray decreases, the lifting assembly slowly moves upward to ensure that the magnetic core adsorption assembly can always adsorb the top magnetic core without frequent adjustment of the adsorption height; when the top magnetic core tray is empty, the tray gripping assembly moves the empty tray to the empty tray shelf 1063, and the lifting assembly then drives the shelf to move upward to fill the adsorption station with the next new magnetic core tray.

[0035] As a further preferred embodiment, the transformer coating assembly 2 includes a middle frame 201 and a transformer conveying channel 202, a conveyor belt turntable 203, a transfer module 204, an outer workpiece turntable 205, an inner workpiece turntable 206, a drive motor 207, and a drive cutter 208, all mounted on the middle frame 201. Two sets of inner workpiece turntables 206 are rotatably mounted on the outer workpiece turntable 205. The drive motor 207 is located at the lower end of the left inner workpiece turntable 206. The upper end of the drive motor 207 has a drive arm 2071 for rotating the inner workpiece turntable 206. A transmission rod 2061 is located at the bottom of the inner workpiece turntable 206, and a workpiece placement slot 2062 is located at the top of the inner workpiece turntable 206. The rotation of the outer turntable 205 drives the inner turntable 206 on the right to rotate to the left position, and places the transmission rod 2061 of the inner turntable 206 inside the drive arm 2071. The drive motor 207 drives the inner turntable 206 on the left to rotate through the drive arm 2071 and the transmission rod 2061. The drive cutter 208 is located between the two sets of inner turntables 206. The tape placed on the tape turntable 203 winds the transformer inside the workpiece placement slot 2062 through the guide rod 2031. The transfer module 204 transfers the transformer in the transformer transfer channel 202 on the left to the workpiece placement slot 2062 and transfers the transformer in the workpiece placement slot 2062 to the transformer transfer channel 202 on the right.

[0036] Adopting a dual-station alternating operation mode, the right station feeds material simultaneously while the left station is winding, and the next round of winding begins immediately after the station switch, with no downtime waiting time. Compared with single-station equipment, the gluing efficiency is nearly doubled in the same amount of time, adapting to the rhythm of large-scale production lines. Only one tape turntable supplies glue to both stations, eliminating the need for additional tape supply components, reducing equipment costs and space occupation. At the same time, when switching stations, the tape naturally stretches as the workpiece moves, completing the initial bonding of the new workpiece, avoiding tape waste and reducing consumable costs.

[0037] As a further preferred embodiment, the outer turntable 205 of the workpiece includes a large gear 2051, a small gear 2052, a second drive motor 2053, and a timing belt 2054. The large gear 2051 is connected to the small gear 2052 through the timing belt 2054. The output end of the second drive motor 2053 is connected to the small gear 2052. Two sets of fixed platforms 20555 are fixed inside the outer turntable 205 of the workpiece. The middle part of the inner turntable 206 of the workpiece is rotatably disposed inside the fixed platform 2055. The upper end of the transmission rod 2061 is rotatably disposed inside the inner turntable 206 of the workpiece and is fixedly connected to it. After the second drive motor starts, its output shaft drives the small gear plate to rotate; the small gear plate transmits power to the large gear plate through the synchronous belt; the two sets of fixed tables rotate 180° with the large gear plate, thereby driving the two sets of workpiece inner turntables to complete the workstation switching.

[0038] The drive cutter 208 includes a drive motor 2081, a connecting rod assembly 2082, a guide rail 2084, a slider 2085, and a cutter 2083. The output end of the drive motor 2081 is rotatably connected to one end of the connecting rod assembly 2082, and the other end of the connecting rod assembly 2082 is rotatably connected to the slider 2085. The slider 2085 is slidably disposed on the guide rail 2084, and the cutter 2083 is mounted on the slider 2085. After the drive motor starts, its output shaft rotates in a circular motion, which is converted into the linear reciprocating motion of the slider through the linkage assembly. After the station switch is completed, the slider drives the cutter to extend along the guide rail between the inner turntables of the two sets of workpieces. The cutting edge of the cutter contacts and cuts the tape between the two transformers. After cutting, the motor reverses, the linkage drives the slider to reset, and the cutter exits the station. The linkage transmission, combined with the sliding of the guide rail, ensures that the cutter extends into the same position each time, accurately acting on the tape between the two transformers.

[0039] The transfer module 204 includes a linear track assembly 2041, a left transport gripper 2042, and a right transport gripper 2043. Both the left transport gripper 2042 and the right transport gripper 2043 include a lifting assembly 2044 and a pneumatic gripper 2045. The linear track assembly 2041 is mounted on the middle frame 201. The upper end of the lifting assembly 204 is mounted on the linear track assembly 2041, and the pneumatic gripper 2045 is mounted on the lower end of the lifting assembly 2044.

[0040] The linear track assembly has built-in drive components (such as servo motors and synchronous belts) that can drive the left and right transport grippers to move precisely to the designated positions along the track (the left gripper corresponds to the left end conveyor channel and the right workpiece inner turntable, and the right gripper corresponds to the right end workpiece inner turntable and the right end conveyor channel). The lifting assembly (such as cylinders and electric push rods) can drive the pneumatic grippers to move up and down; the pneumatic grippers open and close using air pressure, which can stably clamp the transformer.

[0041] As a further preferred embodiment, the transformer dispensing assembly 3 includes a rear frame 301, a transfer module 302 disposed on the rear frame 301, a rotary table 303, a transformer fixture 304, and a dispensing assembly 305. The transformer fixture 304 includes a front fixture 3041 and a rear fixture 3042 disposed opposite to each other. The front fixture 3041 and the rear fixture 3042 are provided with two sets of workpiece placement slots 3043 inside. The dispensing assembly 305 is provided with... The dispensing assembly 305, located at the upper end of the rear fixture 3042, includes a driving assembly 3051, a first dispensing nozzle 3052, and a second dispensing nozzle 3053. The driving assembly 3051 drives the first dispensing nozzle 3052 and the second dispensing nozzle 3053 to dispense adhesive onto both sides of the transformer in the front fixture 3041, respectively. The transfer module 302 transfers the transformer to be dispensed to the rear fixture 3042 and transfers the already dispensed transformer out of the rear fixture 3042.

[0042] By using dual-fixture rotation and parallel loading / unloading with dispensing, the idle time of traditional single-station equipment is eliminated, improving equipment utilization and significantly reducing the dispensing time per transformer. The fixture placement slot and automated dispensing nozzle replace manual positioning, minimizing glue dot offset and reducing the difference in glue layer thickness on both sides, thus greatly reducing the defect rate. From loading / unloading to dispensing and unloading, no manual intervention is required, allowing direct integration into the transformer production line, reducing bumps and damage caused by manual handling, and minimizing human interference in the production process.

[0043] As a further preferred embodiment, the drive assembly 3051 includes a second translational linear track assembly 3055 and a second vertical linear track assembly 3054. The second vertical linear track assembly 3054 is disposed at the upper end of the second translational linear track assembly 3055, and the first dispensing nozzle 3052 and the second dispensing nozzle 3053 are disposed at the rear end of the second vertical linear track assembly 3054. Based on the transformer's height, the nozzle is lowered to the dispensing position (close to the surface of the transformer to be dispensed). After dispensing, it is moved upwards to avoid collisions between the nozzle and the fixture or the transformer. After dispensing on one side of the transformer, the vertical track assembly (and dual nozzles) is moved horizontally to the left, aligning the nozzle with the dispensing position on the other side of the transformer. This allows for dual-sided dispensing without moving the fixture. The track assembly uses linear guides and servo drives, minimizing horizontal and vertical movement errors and ensuring precise alignment of the dual nozzles with the dispensing position each time.

[0044] The rotary table 303 includes a fixed platform 3031 and a rotary cylinder 3032. The front fixture 3041 and the rear fixture 3042 are disposed on the fixed platform 3031, and the rotary cylinder 3032 is installed at the lower end of the fixed platform 3031. After receiving the control signal, the rotary cylinder 3032 drives the fixed platform 3031 to rotate 180° around the vertical axis. The 180° rotation of the rotary table allows feeding, discharging, and dispensing to be carried out simultaneously at different workstations. When the dispensing assembly processes the front fixture, the rear fixture is simultaneously fed and discharged. There is no waiting time for the equipment, which greatly improves the overall production cycle.

[0045] The transfer module 2 302 includes a linear track assembly 2 3021, a left transport gripper 2 3022, and a right transport gripper 2 3023. Both the left transport gripper 2 3022 and the right transport gripper 2 3023 include a lifting assembly 2 3024 and a pneumatic gripper 2 3025. The linear track assembly 2 3021 is mounted on the rear frame 301. The upper end of the lifting assembly 2 302 is mounted on the linear track assembly 2 3021, and the pneumatic gripper 2 3025 is mounted on the lower end of the lifting assembly 2 3024.

[0046] The linear track assembly 3021 drives the left and right grippers to move horizontally, enabling the grippers to switch positions between the loading area and the fixture position, and between the fixture position and the unloading area. The lifting assembly 3024 drives the pneumatic gripper 3025 to move vertically, enabling the grippers to move downwards to grab and place the transformer, and to move upwards to avoid collisions. The pneumatic gripper 3025 uses air pressure to open and close, grabbing the transformer to be glued (loading) or placing the already glued transformer (unloading).

[0047] In a further preferred embodiment, the characteristic testing component 4 includes a testing platform 401, a transfer module 3 402, a testing conveyor belt 403, and a transformer conveying channel 404. The testing platform 401 is located on the right side of the transformer coating assembly 2. The transfer module 1 204 in the transformer coating assembly 2 transfers the transformer after testing on the testing platform 401 to the testing conveyor belt 403. The transfer module 3 402 moves the transformer on the testing conveyor belt 403 to the transformer conveying channel 404. The testing conveyor belt 403 is used to discharge defective products.

[0048] After the transformer is coated with rubber, it is directly transferred to the testing station by transfer module one. After the test is completed, it is transferred to transfer channel four (for qualified products) or the testing conveyor belt (for unqualified products) by transfer module three. No manual handling is required, and the process connection time is short. Unqualified products are discharged separately through the testing conveyor belt, which is physically isolated from qualified products.

[0049] As a further preferred embodiment, the laser marking assembly 5 includes a transformer conveying channel 501, a transfer module 502, a marking table 503, a laser marking machine 504, and a transfer module 505. The transformer conveying channel 501 is located at the rear end of the transformer dispensing assembly 3. The transfer module 502 moves the transformer in the transformer conveying channel 501 to the marking table 503. The laser marking machine 504 is located at the rear end of the marking table 503. The transfer module 505 moves the transformer on the marking table 503 to the discharge tray 6.

[0050] Transfer module four transfers the dispensing transformer to the marking station. After marking is completed, transfer module five directly transfers it to the discharge tray without manual assistance, greatly reducing the marking time per unit.

[0051] like Figures 1-12 As shown, the working process of this application is as follows: I. Assembly process of the two sets of magnetic cores of the transformer: Preparation stage: 1. The front magnetic core mounting module 104 and the rear magnetic core mounting module 105 prepare and load the front and rear magnetic cores. Specifically, in the transfer module 107, the lifting component 1072 and the magnetic core adsorption component 1073 are driven by the linear track component 1071. The magnetic core adsorption component 1073 adsorbs a row of magnetic cores in the magnetic core disk 106 and transfers them to the magnetic core group conveyor belt 1081 on the conveyor platform 108. (After the magnetic adsorption head 10732 inside the magnetic core adsorption component 1073 moves down, it adsorbs the magnetic cores through the pressure plate 10733 and places them on the magnetic core group conveyor belt 1081. After the magnetic adsorption head 10732 moves up, the magnetic force weakens, while the pressure plate 10733 still presses the magnetic cores until the entire magnetic core adsorption component 1073 moves up). Then, a row of magnetic cores on the magnetic core group conveyor belt 1081 is pushed by the side drive push plate 1082 to push the magnetic core group into a neat arrangement. The rear drive push plate 1083 pushes the neatly arranged magnetic core group to the front end of the magnetic core group conveyor belt 1081.

[0052] The transformers in the left-side transformer conveyor channel 102 move to the right in sequence until the last transformer moves to the stop block 1116 and is blocked by the stop block 1116. At the same time, the circular rubber-coated pressure head 1114 also presses down on the end of the rubber tape of the last transformer wire wrapping, preventing it from opening.

[0053] Transformer loading: The stop block 1116, driven by the stop drive assembly 1117, releases the obstruction of the conveying channel; the transfer rod 1111, driven by the vertical transfer drive assembly 1112, is inserted into the inner hole of the transformer and then moves laterally through the horizontal transfer drive assembly 1113. Simultaneously, the transformer's rightward movement pushes the circular rubber-coated pressure head 1114 to rotate upwards until the transformer is moved onto the assembly table 103. Then, the upper pressure head 1118, driven by the pressure head drive assembly 1119, presses the transformer down onto the assembly table 103; then, the circular rubber-coated pressure head 1114, under the influence of gravity and the connecting rod assembly 1115, falls again, blocking the tape head of the next transformer; at the same time, the stop block 1116, driven by the stop drive assembly 1117, blocks the conveying channel, preventing the next transformer from moving; the transfer rod 1111 resets. Rear magnetic core installation: The magnetic core of the rear magnetic core assembly conveyor belt 1081 is driven by the rear drive push plate 1083 and moves down gradually along the arc-shaped guide channel 1086. The arc-shaped limit block 1087 can limit the magnetic core inside the arc-shaped guide channel 1086 from detaching. Then the lowest magnetic core is pushed forward by the front push rod 1094 and the front push cylinder 1095 until the rear magnetic core is installed on the rear side of the transformer.

[0054] Front core installation: The magnetic cores of the front core assembly conveyor belt 1081 move to the front end under the drive of the rear drive push plate 1083. The magnetic core baffle 1084 blocks the frontmost magnetic core under the action of the magnetic core baffle drive assembly 1085 to prevent it from falling. The magnetic core gripper 1091 is rotated 90 degrees backward by the flip cylinder 1093. The magnetic core gripper 1091 clamps the frontmost magnetic core. After receiving the required signal, the magnetic core baffle 1084 moves upward to release the obstruction of the magnetic core. The magnetic core gripper 1091 can smoothly rotate forward 90 degrees under the action of the flip cylinder 1093. After the magnetic core gripper 1091 puts down the magnetic core, it re-grips the magnetic core (aligning it with the rear magnetic core). After adjusting the position, the magnetic core is released. Then, under the action of the front push cylinder 1092, it is installed on the front side of the transformer.

[0055] Material discharge stage: The material discharge module 110 transfers the transformer with two sets of magnetic cores installed to the transformer conveying channel 102 on the right.

[0056] II. Transformer rubber coating assembly process: Material loading stage: The left transport gripper 2042 of the transfer module 204 moves along the linear track assembly 2041 to the left transformer transfer channel 202 (i.e. the right transformer transfer channel 102). It is lowered by the lifting assembly 2044 and clamped by the pneumatic gripper 2045, transferring the uncoated transformer to the workpiece placement slot 2062 of the right workpiece inner turntable 206 of the workpiece outer turntable 205. At this time, the transformer to be coated has been pre-placed in the workpiece placement slot 2062 of the left workpiece inner turntable 206, and the tape on the tape turntable 203 is guided by the guide rod 2031, and its initial end has been bonded to the front end face of the left transformer.

[0057] Left-side winding stage: The transmission rod 2061 at the bottom of the inner turntable 206 of the left workpiece is embedded in the drive arm 2071 of the drive motor 207. The drive motor 207 starts and drives the drive arm 2071 to rotate. Through the transmission rod 2061, the inner turntable 206 of the left workpiece rotates one revolution within the fixed platform 2055 of the outer turntable 205 of the workpiece. During this process, the tape turntable 203 releases tape synchronously with the rotation of the transformer. The tape maintains a stable tension through the guide rod 2031 and is evenly wound around the surface of the left transformer to fix the internal magnetic core.

[0058] Station switching stage: Drive motor 2053 drives the small gear 2052 of the workpiece outer turntable 205 to rotate. The small gear 2052 drives the large gear 2051 to rotate 180° through the synchronous belt 2054, so that the transformer with one turn of tape wrapped on the left side (with tape) rotates to the right station, and the transformer without tape wrapped on the right side rotates to the left station. During the switching process, when the right-side transformer with tape moves with the station, the tape on its surface is pulled out to the right in sync. Because the tension is stable, the pulled-out tape is just stuck to the front end of the newly switched transformer on the left side, completing the automated connection of the initial tape bonding.

[0059] Cutting and unloading stage: The drive motor 2081 of the drive cutter 208 starts, and drives the slider 2085 to slide along the guide rail 2084 through the connecting rod assembly 2082, so that the cutter 2083 extends into the inner turntable 206 of the two sets of workpieces and accurately cuts the tape connecting the two transformers; then the right transport gripper 2043 of the transfer module 204 moves to the right station, clamps the transformer that has been coated with glue and transfers it to the right transformer conveying channel 202 to complete the unloading.

[0060] Cyclic operation: Repeat the above steps to achieve a continuous cycle of uncoated transformer loading, left-side winding, station switching, tape cutting, and finished product unloading.

[0061] III. Transformer Characteristic Testing Procedures: Transfer module 2 302 moves the coated transformer to the testing platform 401. The transformer on the testing platform 401 undergoes inductance, capacitance and other characteristic tests through the testing equipment. If the test fails, transfer module 3 402 places the tested transformer onto the testing conveyor belt 403. The testing conveyor belt 403 sends out the unqualified transformer, while the qualified transformer is directly transferred to the transformer conveying channel 404 via transfer module 3 402.

[0062] IV. Transformer dispensing process: Material loading stage: The left transport gripper 3022 of the transfer module 302 moves along the linear track assembly 3021 to accurately place the transformer to be glued in the four transfer channels 404 into the two sets of placement slots 3043 of the rear fixture 3042, completing the initial material loading.

[0063] The first set of dispensing and parallel feeding: The rotary cylinder 3032 of the rotary table 303 drives the fixed platform 3031 to rotate 180°, so that the rear fixture 3042 (containing the transformer to be dispensed) is rotated to the bottom of the dispensing assembly 305, and the front fixture 3041 is rotated to the rear side; the first dispensing nozzle 3052 and the second dispensing nozzle 3053 move down in the vertical linear track assembly 3054 to apply glue to the right side of the two sets of transformers to be dispensed in the fixture, then the vertical linear track assembly 3054 moves up, the horizontal linear track assembly 3055 moves to the left, and the vertical linear track assembly 3054 moves down again to apply glue to the left side of the transformer by the first dispensing nozzle 3052 and the second dispensing nozzle 3053; At the same time, the front fixture 3041 rotates to the rear, and the left transport gripper 3022 continues to load the new transformer to be glued into the placement slot 3043 of the front fixture 3041, so as to realize the parallel operation of glue dispensing and material loading.

[0064] The second set of dispensing and parallel unloading: After the first set of dispensing is completed, the fixed platform 3031 rotates 180° again, and the front fixture 3041 (containing the new transformer to be dispensed) moves to the underside of the dispensing assembly 305 for double-sided dispensing; at the same time, the right transport gripper 3023 of the transfer module 302 moves along the linear track assembly 3021 to remove the dispensed transformer from the rear fixture 3042, realizing parallel dispensing and unloading. A set of transformers in the placement slot 3043 is removed by the right transport gripper 3023, and the left transport gripper 3022 enters the loading action.

[0065] Cyclic operation: Repeat the above steps, with the left gripper continuously feeding material, the right gripper continuously discharging material, the rotary table changing fixtures, and the dispensing assembly continuously dispensing glue, forming a closed-loop automated process.

[0066] V. Transformer laser marking process: As a further preferred embodiment, the laser marking assembly 5 includes a transformer conveying channel 501, a transfer module 502, a marking table 503, a laser marking machine 504, and a transfer module 505. The transformer conveying channel 501 is located at the rear end of the transformer dispensing assembly 3. The transfer module 502 moves the transformer in the transformer conveying channel 501 to the marking table 503. The laser marking machine 504 is located at the rear end of the marking table 503. The transfer module 505 moves the transformer on the marking table 503 to the discharge tray 6.

[0067] The transfer module 4 502 moves the transformer that has been glued in the transformer transfer channel 5 501 to the marking table 503, where the laser marking machine 504 performs laser marking on the transformer.

[0068] Transformer mounting process: After marking is completed, the transfer module 505 moves the transformer on the marking table 503 to the discharge tray 6 for loading.

It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of the present invention without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of the present invention through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
