Description

Technical Field

[0001] This invention relates to the pretreatment of high-frequency transformer cores, specifically to an automated and rapid operation device for dispensing adhesive onto the edge posts of the core. Background Technology

[0002] High-frequency transformers are power transformers operating at frequencies exceeding intermediate frequencies (10kHz), and are key components in switching and inverter power supplies. Most high-frequency transformers have three core posts: the middle post (called the center post) and the two outer posts (called the side posts). The dispensing process for high-frequency transformers involves applying, spraying, dripping, or filling electronic adhesive onto the core posts to fix, bond, insulate, or smooth the surface of the transformer's electronic components. Dispensing onto the side posts is done on the end faces of the side posts. In the mass production of high-frequency transformers, a stable and reliable dispensing process and result for the side posts largely determine the effectiveness of core assembly and the consistency of inductance (i.e., the electronic adhesive applied to the side post end faces ensures good overall magnetic conductivity for the two cores that have been bonded and fixed together in subsequent processes).

[0003] Since the magnetic cores of different high-frequency transformers may have side posts with different shapes, the dispensing of adhesive to the magnetic core side posts in production is still mainly done manually. However, the dispensing process for magnetic core side posts is cumbersome (especially when the end face of the magnetic core side post has irregular shapes such as concave curvature), and includes at least the processes of applying adhesive to a flat plate, flattening with rollers, inverting the magnetic core, and extruding coating. Moreover, manual operation is inefficient and inconsistent, and has become a common key technology that urgently needs to be improved in the industry's development.

[0004] Currently, only a small number of high-frequency transformers in very large-scale production use dispensing valves, scraper meshes, and other methods for auxiliary dispensing of magnetic core side posts. For example, the scraper machine proposed in Chinese patent CN212069367U, which can control the amount of glue on the transformer core side posts, meets the diverse dispensing process requirements of magnetic core side posts through the scraper mesh and the position of the opening. However, the scraper mesh is prone to inconsistent glue usage and leakage. To address this, Chinese patent CN212732820U utilizes a gluing carrier and a carrier drive assembly to uniformly perform gluing (extrusion coating), UV curing (improving gluing reliability), and material collection processes on magnetic cores arranged on a transfer plate. However, the carrier drive assembly moves sequentially between workstations, and each workstation (e.g., the glue tank) remains idle after completing one operation, resulting in low overall efficiency. Furthermore, the magnetic cores tend to stick together after gluing and UV curing, hindering integration with subsequent production operations. In contrast, Chinese patent CN118098804A utilizes positioning blocks in each fixture, along with an upper scraper and a lower lifting assembly, to improve the bonding quality of magnetic chips of the same specifications. Multiple fixtures are used to prevent magnetic core sticking. However, manual operation is required for fixing the magnetic chips before gluing and for checking the gluing effect (and removing the magnetic cores). In addition, Chinese patent CN115430785A introduces multiple gripper cylinders (i.e. pneumatic grippers) for clamping / releasing products, thereby enabling the products to move in and out of the dispensing station. However, since dispensing is only performed when the dispensing station moves to the dispensing device position, the dispensing operation is not continuous. Summary of the Invention

[0005] The purpose of this invention is to provide a high-frequency transformer core edge column dispensing machine, thereby efficiently realizing the integrated and automated dispensing operation of multiple processes, including high-frequency transformer core feeding, material handling and transfer, core edge column dispensing, and finished product output.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] The dispensing machine includes a feeding device, a conveyor belt, a transfer device, a dispensing device, and a discharging device. The feeding device includes a feeding seat and a suction mechanism for loading and unloading high-frequency transformer cores from the feeding seat during the process of moving them to the conveyor belt. The transfer device includes a clamping mechanism for picking up high-frequency transformer cores that have reached the end of the conveyor belt. The dispensing device includes a glue tank, a positioning mechanism for placing the high-frequency transformer cores picked up by the clamping mechanism, an adhesive mechanism for moving the high-frequency transformer cores placed at the positioning mechanism to the glue tank by means of a mechanical flipping motion, and a scraping mechanism for forming a glue layer at the glue tank for pressing the end faces of the high-frequency transformer cores onto the side pillars. The dispensing device includes a dispensing platform and a dispensing mechanism for moving the high-frequency transformer cores with the glue layer pressed onto the end faces of the side pillars at the glue tank to the dispensing platform by means of a mechanical flipping motion.

[0008] Preferably, the material suction mechanism specifically includes a magnet, an upper suction cylinder that can move horizontally above both the material feeding seat and the conveyor belt, and a material suction base plate connected to the upper suction cylinder. A lower suction cylinder is provided on the material suction base plate, and the magnet is provided on the magnet base plate connected to the lower suction cylinder. A material suction plate connected to the material suction base plate is provided below the magnet base plate. The high-frequency transformer core does not have magnetism, but it can be attracted by the magnet.

[0009] Preferably, the feeding device further includes a pressing mechanism, which specifically includes a pressing plate used to block high-frequency transformer cores arranged in other positions in the feeding seat during the loading of a row of high-frequency transformer cores by means of enhanced magnetic adsorption (specifically, the high-frequency transformer cores are adsorbed to the suction plate as the magnet moves down). The pressing plate is connected to the suction mechanism (specifically, the suction base plate) through a pressing spring that can be compressed downward or upward.

[0010] Preferably, the pressing mechanism further includes a pressing block that can move up and down relative to the suction mechanism (specifically the suction base plate), a pressing spring is disposed on the top of the pressing block, and a pressing sheet is disposed on the pressing block.

[0011] Preferably, the feeding device further includes a material balancing mechanism, which specifically includes a scale set on the side of the conveyor belt away from the unloading seat and a material balancing plate used to adjust the position of the corresponding high-frequency transformer core on the conveyor belt to the material balancing plate adjacent to the scale during or after unloading of the entire row of high-frequency transformer cores by means of weakening the magnetic attraction effect (specifically, as the magnet moves up and resets, the high-frequency transformer core no longer attracts to the suction plate) by pushing.

[0012] Preferably, the feeding device further includes a discharge mechanism, which specifically includes a discharge plate for pushing out the high-frequency transformer cores arranged in the feeding seat row by row and for the feeding mechanism to load the cores.

[0013] Preferably, the feeding device further includes a feeding motor, which is connected to the discharge plate via a synchronous belt mechanism located outside the discharge seat.

[0014] Preferably, the transfer device further includes a movable block that can move horizontally above both the end of the conveyor belt and the positioning mechanism, and a gripping cylinder disposed on the movable block, wherein the gripping mechanism is connected to the gripping cylinder.

[0015] Preferably, the transfer device further includes a transfer housing and a transfer motor, the moving block cooperates with a slide rail disposed in the transfer housing, and the transfer motor is connected to the moving block through a synchronous belt mechanism disposed in the housing.

[0016] Preferably, the glue tank specifically includes a temperature-controlled glue scraper box and a glue scraper platform disposed inside the glue scraper box. The glue scraper platform includes a glue groove for supporting the glue layer, and the sides of the glue scraper box are respectively provided with notches for the glue-adhesive mechanism and the discharge mechanism to be embedded.

[0017] Preferably, the dispensing device further includes an adhesive motor, the main shaft of which is connected to the adhesive mechanism. When the main shaft of the adhesive motor rotates forward by a certain angle (e.g., 90°), the adhesive mechanism swings to the positioning mechanism. When the main shaft of the adhesive motor rotates backward by a certain angle (e.g., 180°), the adhesive mechanism drives the high-frequency transformer core, which has been placed at the positioning mechanism, to swing to the glue pool.

[0018] Preferably, the discharge device further includes a discharge motor, the main shaft of which is connected to the discharge mechanism. When the main shaft of the discharge motor rotates forward by a certain angle (e.g., 90°), the discharge mechanism swings to the glue tank. When the main shaft of the discharge motor rotates backward by a certain angle (e.g., 180°), the discharge mechanism drives the high-frequency transformer core (whose side column end face is pressed onto the glue layer) at the glue tank to swing to the discharge platform.

[0019] Preferably, the discharge device further includes a straight push plate for sequentially rearranging the high-frequency transformer cores (whose side column end faces have been glued by pressing onto the adhesive layer) in the same direction (e.g., perpendicular to the incoming material direction) within the discharge platform (e.g., rotating the high-frequency transformer cores corresponding to the row in the feeding seat by 90 degrees according to their respective arrangement orientations and then arranging them closely together), and a horizontal push plate for moving the high-frequency transformer cores rearranged by the straight push plate out in another direction (e.g., perpendicular to the rearranged direction) within the discharge platform. The straight push plate and the horizontal push plate are correspondingly connected to the push cylinders respectively arranged in the corresponding directions on the outside of the discharge platform.

[0020] Preferably, the discharge device further includes a material blocking plate for separating the discharge platform (for example, separating the discharge platform in the direction of the rearranged high-frequency transformer core, so that the high-frequency transformer core moving to the discharge platform is rearranged on one side of the material blocking plate and reaches the other side of the material blocking plate when it is moved out) and a material blocking cylinder disposed above the discharge platform, the material blocking plate being connected to the material blocking cylinder.

[0021] Preferably, the gripping mechanism, adhesive mechanism, and discharge mechanism are grippers, for example, all of which adopt a gripper design with pneumatic fingers.

[0022] Preferably, the dispensing machine further includes a frame and a worktable mounted on the frame. The feeding seat, conveyor belt, glue tank, discharge table, discharge motor, and adhesive motor are all mounted on the worktable. The lower part of the positioning mechanism is located inside the frame, and the upper part of the positioning mechanism (e.g., a positioning block) is located on the worktable.

[0023] Preferably, the dispensing machine also includes a controller (e.g., a PLC) mounted on the frame. The controller is connected to the drivers of each motor in the machine (specifically including the discharge motor, adhesive motor, transfer motor, feeding motor, etc.) and the control units (e.g., air source valves such as solenoid valves mounted on the frame) of the actuators (specifically including each cylinder, pneumatic fingers, etc.).

[0024] The beneficial effects of this invention are reflected in:

[0025] This invention is based on the automated and integrated operation design of feeding high-frequency transformer cores in rows and unloading them at the end of the dispensing process. By picking up the high-frequency transformer cores from the conveyor belt at the end of the conveyor belt and placing them into the positioning mechanism, continuous and reliable dispensing of the core side posts can be achieved at the glue pool using the adhesive structure and the discharge mechanism. This avoids the high-frequency transformer cores sticking together after dispensing. Compared with manual operation, it can ensure precise control of the amount of glue dispensed to the core side posts and good consistency of the dispensing operation, which is conducive to improving product quality and has significant economic benefits.

[0026] Furthermore, the clamping mechanism, adhesive mechanism, and discharge mechanism in this invention adopt a claw design, which can be applied to the core edge column adhesive application needs of various specifications and models of high-frequency transformer cores, such as can type, RM type, E type, EC type, ETD type, EER type, PQ type, and EP type.

[0027] Furthermore, based on the miniaturization of the glue pool (since the high-frequency transformer cores are glued sequentially at the glue pool), this invention combines glue pool temperature control with the use of different glue scraping stations (specifically, glue tank depths are different, i.e., glue layer thicknesses are different) for glue scraping. This ensures the controllability of the glue thickness applied to the end face of the high-frequency transformer core (thus meeting the requirements of different core end glue dispensing processes) and allows the equipment (mainly referring to the dispensing device, etc.) to maintain a more efficient operating state.

[0028] Furthermore, based on the modular design of the whole machine, the present invention can also utilize the main shaft phase of the adhesive motor and the discharge motor for equipment installation and debugging, thereby effectively improving the overall operating efficiency of the machine in production and ensuring the high efficiency and speed of use, operation and maintenance.

Detailed Implementation

[0047] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. The embodiments described are for illustrative purposes only and are not intended to limit the scope of protection of the present invention.

[0048] Example 1

[0049] See Figure 1A The high-frequency transformer core edge column dispensing machine of the present invention mainly includes a feeding device 1, a conveyor belt 2, a transfer device 3, a dispensing device 4, a discharging device 5, a controller 6, a worktable 7, a frame 8, and solenoid valves 9. The worktable 7 is mounted on the top of the frame 8, the controller 6 is mounted on the front side of the frame 8, and multiple solenoid valves 9 are mounted on the rear side of the frame 8. The feeding device 1 is mounted on the worktable 7, and its working position is close to the left edge of the worktable 7. The conveyor belt 2 is mounted on the worktable 7 to the right of the working position of the feeding device 1, with the starting end of the conveyor belt 2 close to the front edge of the worktable 7 and the ending end of the conveyor belt 2 close to the rear edge of the worktable 7. The transfer device 3 is mounted on the worktable 7, and the starting point of the working position of the transfer device 3 is located above the end of the conveyor belt 2. The glue dispensing device 4 and the discharge device 5 are both located on the right side of the conveyor belt 2. The discharge device 5 is installed on the workbench 7 and close to the front edge of the workbench 7. The glue dispensing device 4 is installed in the area of ​​the workbench 7 between the discharge device 5 and the transfer device 3. The end point of the working position of the transfer device 3 and the working position of the glue dispensing device 4 are arranged from far to near in the material direction of the discharge device 5. The power source (e.g., motor) used to transport the high-frequency transformer core according to the process flow in the feeding device 1, conveyor belt 2, transfer device 3, glue dispensing device 4, and discharge device 5, as well as the solenoid valves 9 required to complete each process, are all connected to the controller 6 through cables. In addition, the controller 6 is also used to control the process parameters (e.g., control the glue temperature in the glue dispensing device 4 through the connected temperature measurement and heating module).

[0050] Combination Figure 1B As shown, the controller 6 can control the air circuits of corresponding actuators in the feeding device 1, transfer device 3, dispensing device 4, and discharging device 5 via the solenoid valve 9. Specifically, when the solenoid valve 9, which is connected to the air source through an external air pipe, opens or closes according to the signal from the controller 6, the corresponding actuators connected to the internal air pipe (one end of the internal air pipe is connected to the solenoid valve 9 via a pneumatic connector, and the other end extends from a pre-drilled hole on the workbench 7 to facilitate connection to the pneumatic interface on the actuator via a pneumatic connector, see details) will be controlled. Figure 1A (That is, the rest of the internal air tube can be installed inside the frame 8) to operate, such as making the pneumatic fingers grip or release the high-frequency transformer core, or making the cylinder output linear motion in the required direction, thereby achieving a more integrated and efficient automated dispensing operation based on the control of the power source.

[0051] See Figure 2AThe feeding device 1 mainly consists of a feeding motor 11, a discharge mechanism 12, a balancing mechanism 13, a suction mechanism 14, a transfer cylinder 15, a transfer slide rail 16, a suction table 17, a discharge seat 18, and a pressing mechanism 19. The discharge seat 18 is made of aluminum AL6061, with a flat-bottomed straight-through groove structure on the top (which can neatly arrange the high-frequency transformer cores after turning over and reserve working positions). The discharge seat 18 (specifically its bottom) is fixed on an installation reference surface located on the workbench 7 and extending outward from the left edge of the workbench 7 for a certain length (in conjunction with...). Figure 1A As shown, specifically, the upper surface of a partition made of aluminum AL6061 and fixed to the front left edge of the workbench 7 is used as the reference surface. On the mounting reference surface, the material feeding seat 18 is located at a position slightly to the right of the center. The working position of the feeding device 1 is located at the right edge of the material feeding seat 18, and a certain distance is left between it and the conveyor belt 2 (ensuring that it does not contact the conveyor belt 2). By controlling the feeding motor 11, the high-frequency transformer core can be moved to this working position by the discharge mechanism 12. The suction table 17 is fixed on the workbench 7, and the fixed position is located on the right side of the conveyor belt 2. The material transfer slide rail 16 and the material transfer cylinder 15 are arranged from left to right on the suction table 7. On the platform 17, the suction mechanism 14 is mounted on the transfer slide rail 16, and the suction mechanism 14 is connected to the cylinder push rod of the transfer cylinder 15; the pressing mechanism 19 is used to prevent other high-frequency transformer cores that are not in the working position of the feeding device 1 from being disturbed and misloaded when the suction mechanism 14 loads the high-frequency transformer cores (i.e., loading), and at the same time, to avoid damage to other high-frequency transformer cores during loading as much as possible; the aligning mechanism 13 is used to keep the high-frequency transformer cores loaded by the suction mechanism 14 from the working position of the feeding device 1 neatly arranged after being unloaded at the conveyor belt 2 (and the arrangement position is adjusted with reference to the starting point of the working position of the transfer device 3).

[0052] See Figure 2B The material discharge mechanism 12 includes a material discharge plate 121 and a support arm 122 respectively located on the front and rear sides of the material discharge seat 18 (the two support arms 122 are respectively fixed at the corresponding side edges of the mounting reference surface, see details). Figure 1ABoth of these support arms 122 are equipped with synchronous belt mechanisms. The discharge plate 121 is located above the discharge seat 18 and can be driven by the synchronous belt mechanisms on the two support arms 122. Specifically, the discharge plate 121 is supported between the two corresponding support arms 122 by a liner 124 fixed on the synchronous belt of the two synchronous belt mechanisms. The probe 125 of the slotted sensor is fixed on the outside of the liner 124. The two slot seats 126 of the slotted sensor are fixed on the lower part of the support arm 122. One slot seat 126 is located on the left side of the discharge seat 18, and the other slot seat 126 is located on the left side of the working position of the feeding device 1. Each of the two synchronous belt mechanisms has a synchronous pulley (specifically located at the left end of the corresponding support arm 122) coaxially connected to the main shaft of the feeding motor 11 through a coupling 123.

[0053] like Figure 2B As shown, after several rows of neatly arranged high-frequency transformer cores 10 (with their core side column end faces all facing upwards) are placed in the feeding seat 18, the feeding mechanism 12 (specifically the feeding plate 121) can push the high-frequency transformer cores 10 to move to the right by a fixed distance (this distance is achieved by controlling the feeding motor 11) until the first row of high-frequency transformer cores 10 on the right enters the working position of the feeding device 1.

[0054] See Figure 2C The material straightening mechanism 13 mainly consists of a material straightening cylinder 131 and a material straightening plate 132; there are two material straightening cylinders 131, which are respectively located on the outer side of the right end of the corresponding support arm 122 (the two material straightening cylinders 131 are respectively connected to the worktable 7 through supports fixed on the worktable 7, see details). Figure 1A The forming plate 132 adopts an irregular plate structure (made of aluminum AL6061) with a flat right edge and two spaced cantilever arms on the left edge. The two cantilever arms are respectively connected to the cylinder push rods of the two forming cylinders 131 and keep the forming plate 132 in the horizontal direction. The right edge of the forming plate 132 is used to push the row of high-frequency transformer cores unloaded onto the conveyor belt 2 toward the corresponding side of the scale 133 (made of aluminum AL6061) assembled on the right side cover of the conveyor belt 2 during the process of the forming cylinder 131 driving the forming plate 132 to move to the right from the left cover of the conveyor belt 2.

[0055] See Figure 2DThe suction mechanism 14 mainly consists of a suction base plate 141, a lower suction cylinder 142, an upper suction cylinder 143, a transfer plate 144, a magnetic base plate 145, a magnet 146, and a suction plate 147. There are two lower suction cylinders 142, which are respectively installed at the front and rear ends of the suction base plate 141. The cylinder push rods of the two lower suction cylinders 142 are connected to the magnetic base plate 145 (made of aluminum AL6061), thereby suspending the magnetic base plate 145 in parallel on the suction plate. Below the material base plate 141, the bottom of the magnetic base plate 145 is tightly fixed to the magnet 146; the suction cylinder 143 is installed on the left side of the transfer plate 144, and the right side of the transfer plate 144 is installed on the cylinder push rod of the transfer cylinder 15. The bottom of the transfer plate 144 is connected to the transfer slide rail 16, so that the suction cylinder 143 can slide left and right inside the suction table 17 (that is, the suction cylinder 143 is assembled on the transfer slide rail 16 through the transfer plate 144, see details). Figure 2A The cylinder push rod of the suction cylinder 143 is connected to the suction base plate 141. A pressing mechanism 19 and a suction plate 147 (made of aluminum AL6061) are installed sequentially from the outside to the inside on the left end face of the suction base plate 141. The suction plate 147 has a strip-shaped mounting hole at its upper part, allowing adjustment of its mounting height before fixing. It is then fixed to the left end face of the suction base plate 141 using screws inserted through the mounting hole. The bottom of the suction plate 147 is an "L" shape bent to the right, giving it a horizontal plate structure located directly below the magnet 146. When the magnet 146 on the magnet base plate 145 is driven by the suction cylinder 142 from its initial position (the distance between the magnet 146 and the bottom horizontal plate structure of the suction plate 147 satisfies the bottom water level requirement), the suction plate 147 is activated. When the flat plate structure is no longer within the magnetic attraction range of magnet 146 (determined by the position) and approaches (or contacts) the upper surface of the bottom horizontal plate structure of the suction plate 147, a row of high-frequency transformer cores located at the working position of the feeding device 1 can be attracted by the magnetic force of magnet 146 and adsorbed onto the lower surface of the bottom horizontal plate structure of the suction plate 147 (i.e., magnet 146 and high-frequency transformer cores are separated on both sides of the bottom of the suction plate 147), at which point the loading is completed; then, the magnet 146 on the magnet base plate 145 is driven away from the bottom of the suction plate 147 and returns to its initial position under the drive of the suction cylinder 142, so that the high-frequency transformer cores are no longer adsorbed onto the lower surface of the bottom horizontal plate structure of the suction plate 147, i.e., the high-frequency transformer cores are released from the suction plate 147, at which point the unloading is completed.

[0056] See Figure 2EThe pressing mechanism 19 includes a pressing plate 191, a pressing base plate 192, a pressing nut 193, and a pressing block 194. The pressing base plate 192 is generally U-shaped. Two parallel pressing bolts 196 are fixed on the bottom of the pressing base plate 192 and extend upwards into the inner side of the pressing base plate 192. Each pressing bolt 196 is fitted with a pressing spring 195. The pressing block 194 is movably mounted on the two pressing bolts 196 through two through holes penetrating its upper and lower ends, and presses down on the upper ends of the two pressing springs 195 (i.e., the two pressing springs 195 are appropriately pre-pressed by the pressing block 194). The lower ends of the two pressing springs 195 are pressed against the pressing base plate 194. The bottom inner side of plate 192 is in contact; there are two pressure nuts 193, which are respectively threaded onto a corresponding pressure bolt 196 to lock the pressure block 194 (specifically, to restrict the upward movement of the pressure block 194); the upper part of the pressure plate 191 (made of aluminum AL6061) has a strip-shaped mounting hole, and the pressure plate 191 can be fixed to the left end face of the pressure block 194 by screws passing through the mounting hole (and the installation height of the pressure plate 191 can be adjusted before fixing). The bottom of the pressure plate 191 is an L-shaped bend to the right, and the vertical assembly position of this bottom is lower than the bottom of the suction plate 147 (i.e., there is a height difference, see details). Figure 2D The pressure plate 192 is located to the left of the suction plate 147, and its fixed position is the same as that of the suction plate 147 on the left end face of the suction plate 141. This ensures that the bottom of the pressure plate 191 is positioned horizontally to the left of the bottom of the suction plate 147 (i.e., the bottom of the pressure plate 191 and the bottom of the suction plate 147 are horizontally adjacent but do not overlap; see details). Figure 2D ).

[0057] like Figure 2D and Figure 2EAs shown, when the suction cylinder 143 moves to the left under the drive of the transfer cylinder 15 to the working position above the feeding device 1, loading begins. Specifically, the suction cylinder 143 drives the suction base plate 141 to lower its height, so that before the bottom of the suction plate 147 contacts a row of high-frequency transformer cores located at the working position of the feeding device 1, the bottom of the pressure plate 191 contacts another row of high-frequency transformer cores located to the left of this row of high-frequency transformer cores (i.e., the second row of high-frequency transformer cores arranged from right to left in the feeding seat 18). As the suction base plate 141 continues to lower its height, the height difference between the bottom of the pressure plate 191 and the bottom of the suction plate 147 gradually decreases due to the compression of the pressure spring 195 (i.e., the bottom of the suction plate 147 and the bottom of the position...). The distance between a row of high-frequency transformer cores at the working position of the feeding device 1 gradually decreases, and the compression of the pressure spring 195 reduces the pressure on the bottom of the pressure plate 191, which can avoid damage to the row of high-frequency transformer cores that the bottom of the pressure plate 191 contacts. Therefore, the compressible stroke of the pressure spring 195 after assembly should not be less than the assembly height difference between the bottom of the pressure plate 191 and the bottom of the suction plate 147 until the bottom of the suction plate 147 contacts the row of high-frequency transformer cores at the working position of the feeding device 1. Then, the loading can be completed by corresponding operation of the magnet 146 on the magnet base plate 145 (since the function of the pressure plate 191 is to press down the next row of high-frequency transformer cores, it is ensured that only one row of high-frequency transformer cores is attracted during loading). Before unloading begins, the loaded row of high-frequency transformer cores needs to be driven by the suction cylinder 143 and raised to their original height along with the suction base plate 141. During this process, the bottom of the pressure plate 191 no longer contacts the high-frequency transformer cores in the unloading seat 18, and the pressure spring 195 is restored (i.e., the height difference between the bottom of the pressure plate 191 and the bottom of the suction plate 147 is restored to the initial state when the assembly is completed). Then, driven by the transfer cylinder 15, it moves to the right above the conveyor belt 2 and begins unloading. Specifically, the suction cylinder 143 drives the suction base plate 141 to lower its height again, so that the loaded row of high-frequency transformer cores is lowered to the height of the scale 133 and contacts the transmission belt 2. Then, the unloading can be completed by corresponding operations on the magnets 146 on the magnet base plate 145. Then, the suction base plate 141 is raised, and the loading and unloading can be repeated by repeating the above operations. At certain time intervals (specifically after the discharge plate 121 pushes a row of high-frequency transformer cores to the working position of the loading device 1 each time), the high-frequency transformer cores in the discharge seat 18 are moved to the conveyor belt 2 for the transfer device 3 to pick up.

[0058] See Figure 3The transfer device 3 includes a clamping cylinder 31, a transfer motor 33, a transfer column 34, a transfer housing 36, a clamping mechanism 37, a transfer vertical slide rail 38, and a moving block 39; there are two transfer columns 34, which are fixed near the rear edge of the worktable 7 (see details). Figure 1A The transfer housing 36 is mounted on two transfer columns 34. The transfer housing 36 contains parallel synchronous belt mechanisms 32 and a transfer transverse slide rail 35. The transfer motor 33 is mounted on the bottom right side of the transfer housing 36, and the main shaft of the transfer motor 33 is coaxially connected to the synchronous pulley on the corresponding side of the synchronous belt mechanism 32. A moving block 39 is mounted on the transfer transverse slide rail 35, and the rear end of the moving block 39 is connected to the synchronous belt of the synchronous belt mechanism 32. A clamping cylinder 31 and a transfer vertical slide rail 38 are mounted from top to bottom on the front end of the moving block 39, and their mounting positions protrude from the front side of the transfer housing 36. The clamping mechanism 37 specifically employs pneumatic fingers. The system includes an independent cylinder mounted on the transfer vertical slide rail 38. Driven by this independent cylinder, two finger-shaped clamping rods (made of aluminum AL6061) extending from one side (specifically the lower side) can be brought closer together to clamp a single high-frequency transformer core (specifically, clamping the outer wall of the left and right side pillars of the high-frequency transformer core; applicable high-frequency transformer core models include: can type, RM type, E type, EC type, ETD type, EER type, PQ type, EP type, etc.). When these two finger-shaped clamping rods are reset, the high-frequency transformer core can be released. The cylinder push rod of the clamping cylinder 31 is connected to the clamping mechanism 37 (specifically connected to the other side of the independent cylinder). During the transfer operation, the starting point of the working position of the transfer device 3 is defined as the position where the clamping mechanism 37, driven by the synchronous belt mechanism 32, moves with the moving block 39 to the farthest position on the left side of the transfer housing 36. The ending point of the working position of the transfer device 3 is defined as the position where the clamping mechanism 37, driven by the synchronous belt mechanism 32, moves with the moving block 39 to the farthest position on the right side of the transfer housing 36. That is, both the clamping mechanism 37 without clamping the high-frequency transformer core and the clamping mechanism 37 with clamping the high-frequency transformer core are operated by controlling the transfer motor 33 and the synchronous belt mechanism 32. Driven by the stepping belt mechanism 32, the transfer is realized between the starting point and the ending point of the working position of the transfer device 3. The clamping mechanism 37 is driven by the clamping cylinder 31 to complete the change from unclamped to clamped state during the process of descending / rising at the starting point of the working position of the transfer device 3, and to complete the change from clamped to unclamped state during the process of descending / rising at the ending point of the working position of the transfer device 3 (that is, the clamping mechanism 37 picks up the high-frequency transformer core that is conveyed by the conveyor belt 2 and stops at the end of the conveyor belt 2 in sequence).

[0059] See Figure 4AThe dispensing device 4 mainly consists of a scraper frame 41, a scraper mechanism 42, a scraper cylinder 43, a scraper transverse slide rail 44, a glue tank 45, a glue-adhesive motor 46, a positioning mechanism 47, and a glue-adhesive mechanism 48; the scraper frame 41 is fixed on the worktable 7 and located on the right rear side of the suction table 17 (see details). Figure 1A The glue scraping transverse slide rail 44 and the glue scraping cylinder 43 are arranged sequentially from left to right on the glue scraping table 41; the glue scraping mechanism 42 is located on the glue scraping transverse slide rail 44, and the glue scraping mechanism 42 is connected to the cylinder push rod of the glue scraping cylinder 43; the glue tank 45 is fixed on the worktable 7 and located below the glue scraping mechanism 42; the positioning mechanism 47 is installed on the rear side of the glue tank 45 and located below the end point of the working position of the transfer device 3; the glue-adhesive motor 46 is fixed on the worktable 7, and the glue-adhesive mechanism 48 extends towards the positioning mechanism 47 and the glue tank 45. The adhesive motor 46 is connected to the main shaft. The adhesive mechanism 48 specifically adopts pneumatic fingers and is fixed to the main shaft of the adhesive motor 46 through its independent cylinder. Thus, as the adhesive motor 46 (specifically its main shaft) rotates in the forward and reverse directions, any high-frequency transformer core transferred to the positioning mechanism 47 can be flipped and moved to the glue pool 45 through the two finger-shaped clamping rods (made of aluminum AL6061) contained in the adhesive mechanism 48 until the end faces of the two side posts of the high-frequency transformer core are directly opposite the glue pool 45.

[0060] Combination Figure 4BAs shown, the positioning mechanism 47 includes a positioning groove on the workbench 7, an upper positioning block 472 mounted in the middle of the positioning groove, and a pneumatic finger for positioning a single high-frequency transformer core. Below the positioning groove is a lower positioning plate 471 fixed within the frame 8. The independent cylinder of the pneumatic finger for positioning the single high-frequency transformer core is fixed to the lower positioning plate 471. This pneumatic finger differs from the aforementioned clamping mechanism 37 and adhesive mechanism 48 mainly in the shape of its respective clamping rod. The pneumatic finger contains two inverted "L"-shaped clamping rods 473 (made of aluminum AL6061), which pass through the positioning grooves upward along the front and rear sides of the upper positioning block 472 (made of aluminum AL6061), respectively. The top of each inverted "L"-shaped clamping rod 473 is bent 90 degrees towards the opposite side and wrapped around the top outer side of the upper positioning block 472, thereby enabling the structure to clamp the corresponding outer side walls of the two side pillars of a high-frequency transformer core in a direction orthogonal to the clamping direction of the two finger-shaped clamping rods of the clamping mechanism 37. When the clamping mechanism 37 descends to its lowest point under the drive of the clamping cylinder 31, it can release the high-frequency transformer core it is holding and place it on top of the upper positioning block 472. This ensures that the high-frequency transformer core maintains the same orientation (i.e., the end face of the core side column is facing upward) after completing the loading, unloading and transfer operations with a row of high-frequency transformer cores from the feeding seat 18. The pneumatic finger used to position a single high-frequency transformer core can release the high-frequency transformer core after adjusting the position of the high-frequency transformer core on the top of the upper positioning block 472 by clamping.

[0061] See Figure 4D The scraping mechanism 42 includes a scraping base plate 421, a left scraping plate 424, a right scraping plate 425, a buffer valve 426, and a scraping plate switching cylinder 427. The scraping plate switching cylinder 427 is fixed at the middle position on the scraping base plate 421. The scraping base plate 421 has through holes through which two cylinder push rods of the scraping plate switching cylinder 427 pass downward. The cylinder push rod of the scraping cylinder 43 is fixed at the right edge of the scraping base plate 421. The scraping base plate 421 is connected to the scraping transverse slide rail 44, so that the scraping plate switching cylinder 427 can slide left and right within the scraping platform 41 (i.e., the scraping plate switching cylinder 427 is mounted on the scraping transverse slide rail 44 through the scraping base plate 421, see details). Figure 4A The left scraper blade 424 and the right scraper blade 425 are arranged alternately in the area below the scraper base plate 421 and directly opposite the glue pool 45. The outer sides of the left scraper blade 424 and the right scraper blade 425 (the outer sides refer to the sides opposite to the scraping direction of the left scraper blade 424 and the right scraper blade 425, i.e., the right side of the left scraper blade 424 and the left side of the right scraper blade 425, see details) Figure 4AEach of the components is equipped with a scraper support plate 422 connected to the scraper base plate 421. The left scraper plate 424 is connected to one of the cylinder push rods of the scraper switching cylinder 427 (near the right edge of the scraper base plate 421) and the scraper vertical slide rail 423 fixed on its outer scraper support plate 422. The right scraper plate 425 is connected to the other cylinder push rod of the scraper switching cylinder 427 (near the left edge of the scraper base plate 421) and the scraper vertical slide rail 423 fixed on its outer scraper support plate 422. Thus, under the drive of the scraper cylinder 43, the left scraper plate 424 connected to the scraper switching cylinder 427 can be rotated. The right scraper blade 425 alternately performs scraping operations at the glue pool 45 below. (When the scraper switching cylinder 427 is about to slide out to the left, it retracts the right scraper blade 425 upwards and extends the left scraper blade 424 downwards. That is, while the scraper switching cylinder 427 slides to the left, the left scraper blade 424 is used to scrape glue within the glue pool 45. When the scraper switching cylinder 427 is about to slide back to the right, it extends the right scraper blade 425 downwards and retracts the left scraper blade 424 upwards. That is, while the scraper switching cylinder 427 slides to the right, the right scraper blade 425 is used to scrape glue within the glue pool 45. See details...) Figure 4A The buffer valves 426 are respectively installed at the left and right corners of the scraper base plate 421 (the two buffer valves 426 installed at the left corner of the scraper base plate 421 are directly opposite to the two left buffer baffles 40 near the left end of the scraper transverse slide rail 44 fixed on the scraper platform 41, and the two buffer valves 426 installed at the right corner of the scraper base plate 421 are directly opposite to the right end of the scraper transverse slide rail 44 fixed on the scraper platform 41 and the right buffer baffle 49 between the scraper cylinder 43, see details). Figure 4A This limits the stroke of the scraper cylinder 43, allowing the left scraper 424 and right scraper 425 connected to the scraper switching cylinder 427 to utilize the buffer valve 426's buffering and deceleration effect after moving into position (avoiding collisions between the left scraper 424, right scraper 425 and the glue pool 45) to ensure the scraping effect and make the scraped glue layer thickness consistent.

[0062] See Figure 4E , Figure 4F and Figure 4GThe glue tank 45 includes a glue scraper box 451, a glue scraping table 452, a temperature sensor 453, and a heating element 454. The glue scraper box 451 (made of aluminum AL6061, with its length × width × height dimensions designed according to the size of a single high-frequency transformer core, for example, 110mm × 50mm × 20mm) has notches on its front and rear sides located at the upper edge of the corresponding sides, which can be aligned with the top of the positioning mechanism 47. The glue scraping table 452 includes a plate (made of D2 steel) disposed within the glue scraper box 451, for... After the glue is poured onto the glue scraper 452 and scraped, a glue layer is formed in the glue box 451 at a certain height above the worktable 7, which serves as the working position of the dispensing device 4. The thickness of this glue layer is controlled by the groove (i.e., glue groove 4521, with a width between 17-30mm) machined through the middle and horizontally through the upper surface of the plate (made of D2 steel). By changing the glue scraper 452 with different groove depths, glue layers of different thicknesses can be formed (after scraping, glue of uniform thickness is distributed in the glue groove 4521, and excess glue is located in the glue box 4521). The glue tank 4521 is located on both sides and is used to fill the glue layer in subsequent glue scraping. Temperature sensor 453 and heating element 454 are installed below the glue scraping table 452. Temperature sensor 453 is fastened to the right side of glue box 451 by a nut, and heating element 454 is fastened to the right side of glue box 451 by an external fixing piece 455. Both temperature sensor 453 and heating element 454 are connected to controller 6 via cables, thereby controlling the glue layer to maintain a preset temperature so that the high-frequency transformer core 10 can be heated to the end faces of its two side posts. After contacting the adhesive layer, a layer of adhesive can be applied quickly, appropriately, and evenly. (The high-frequency transformer core 10 swings from the rear positioning mechanism 47 to the front adhesive pool 45 along with the adhesive bonding mechanism 48. When the adhesive bonding motor 46 reverses 180°, the end face of the uppermost side column of the high-frequency transformer core 10 flips. At this time, as the adhesive bonding mechanism 48 releases the high-frequency transformer core 10 and begins to swing back to the initial position, the corresponding high-frequency transformer core 10 that falls into the adhesive pool 45 will maintain its end face contact with the adhesive layer until it is moved again after the unloading operation.)

[0063] See Figure 5A and Figure 5B The discharge device 5 mainly consists of a discharge mechanism 51, a discharge motor 52, a material blocking cylinder 53, front and rear pushing cylinders 54, a material blocking frame 55, a material blocking plate 56, a discharge platform 57, and left and right pushing cylinders 58; the material blocking frame 55 (made of aluminum AL6061) is fixed on the worktable 7 and located on the right front side of the suction platform 17 (see details). Figure 1AThe discharge platform 57 (made of aluminum AL6061) is installed on the workbench 7 and located below the material blocking frame 55; the material blocking cylinder 53 is installed on the material blocking frame 55, and the cylinder push rod of the material blocking cylinder 53 is connected to the material blocking plate 56 (made of aluminum AL6061), so that the material blocking plate 56 can be driven to move downward a certain distance to divide the discharge platform 57 into two parts (referred to as the front part of the discharge platform 57 and the rear part of the discharge platform 57, respectively); the left and right push cylinders 58 are located on the left side of the discharge platform 57, and the front and rear push cylinders 54 are located on the rear side of the discharge platform 57. The left and right push cylinders 58 and the front and rear push cylinders 54 are respectively connected to the workbench 7 through supports fixed on the workbench 7; the discharge motor 52 is fixed on the workbench 7 in the area enclosed by the front and rear push cylinders 54, the glue tank 45 and the discharge platform 57 (the left side of this area is the suction frame 17, see details). Figure 1A The discharge mechanism 51 is connected to the main shaft of the discharge motor 52. Specifically, the discharge mechanism 51 adopts pneumatic fingers, and the discharge mechanism 51 is fixed to the main shaft of the discharge motor 52 through its independent cylinder. Thus, as the discharge motor 52 (specifically its main shaft) rotates forward and backward, the high-frequency transformer core 10 left in the glue pool 45 is flipped and moved to the receiving area on the discharge table 57 by the two finger-shaped clamping rods (made of aluminum AL6061) contained in the discharge mechanism 51 (this area is located at the rear of the discharge table 57, near the left and right pushers). The material cylinder 58 can be aligned with the notches on the top of the positioning mechanism 47 and the front and rear sides of the glue scraper box 451. That is, when the material discharge mechanism 51 swings its two finger-shaped clamping rods to the receiving area, it releases the clamped high-frequency transformer core 10, thereby placing the high-frequency transformer core 10 in the receiving area (at this time, the high-frequency transformer core 10, after completing the loading, unloading and transfer and glue dispensing operations with a row of high-frequency transformer cores from the material feeding seat 18, still maintains the same orientation and is coated with glue on the two uppermost side column end faces).

[0064] like Figure 5BAs shown, the left and right push cylinders 58 have left and right straight push plates 59 (made of aluminum AL6061) fixed on their cylinder push rods. Driven by the left and right push cylinders 58, the left and right straight push plates 59 can move a certain distance from the left edge of the discharge platform 57 into the discharge platform 57 and then return to their original position. This allows a high-frequency transformer core 10 placed in the receiving area to be pushed to the right (the downward-moving resisting plate 56 prevents the high-frequency transformer core 10 from tilting during the push) and waits for the next high-frequency transformer core 10 placed in the receiving area to be pushed out. The front and rear push cylinders 54 have front and rear horizontal push plates 50 (made of aluminum AL6061) fixed on their cylinder push rods. Driven by the front and rear push cylinders 54, the front and rear horizontal push plates 50 can move a certain distance from the rear edge of the discharge platform 57 into the discharge platform 57 (the resisting plate 56 has already moved upwards before this translation process). After the movement, the high-frequency transformer cores from the feeding base 18 return to their original position before translation. This allows the entire row of high-frequency transformer cores from the feeding base 18 to be moved to the front of the discharging platform 57 after sequentially completing the glue dispensing operation and rearranging at the rear of the discharging platform 57. (Since this row of high-frequency transformer cores is formed by sequentially pushing each core to the right by the left and right push plates 59, each high-frequency transformer core has rotated 90 degrees compared to its orientation on the feeding base 18, thus minimizing the possibility of mutual adhesion after glue dispensing.) This completes the discharging operation of the row of high-frequency transformer cores from the feeding base 18 that has undergone the glue dispensing operation. Afterward, the resist plate 56 moves downward again. The discharging platform 57 can use inductive discharging (i.e., front and rear push proximity sensors 571 and left and right push proximity sensors 572 are respectively located outside the right edge of the discharging platform 57 at the front and rear, respectively, see details). Figure 5A ).

[0065] The automated and integrated process of using the above-mentioned high-frequency transformer core edge column dispensing machine for high-frequency transformer core feeding, material transfer, core edge column dispensing, and finished product output is as follows:

[0066] Step 1: Power-on Preparation

[0067] Check the stability of the equipment's power supply (which supplies power to the controller and each motor) and air supply. Adjust the clamping range of the clamping mechanism 37, the adhesive gluing mechanism 48, and the discharge mechanism 51 to match the size of the high-frequency transformer core. After confirming the thickness of the adhesive layer at the adhesive pool 45 (specifically the depth of the groove at the adhesive scraping table 452) and the remaining amount of adhesive, click "Power On" on the controller 6, and the equipment will begin self-testing.

[0068] Step 2: Begin the work

[0069] After confirming that the feeding seat 18 is in an empty state (based on the signal triggered by the probe 125 of the slot sensor after entering the slot 126 located on the left side of the feeding seat 18), the entire high-frequency transformer core 10 after being turned over is placed in the feeding seat 18, and then the operation program in the controller 6 is started. After the glue temperature in the glue tank 45 reaches the preset temperature, the equipment starts to run automatically.

[0070] Step 3: Loading the first row of magnetic cores

[0071] Under the rightward thrust of the discharge mechanism 12 (specifically the discharge plate 121), the first row of high-frequency transformer cores 10 moves to the working position of the feeding device 1. Then, the transfer cylinder 15 drives the suction mechanism 14 to move to the left above the working position. At this time, the upper suction cylinder 143 pushes the suction base plate 141 down, so that the pressing mechanism 19 first contacts the second row of high-frequency transformer cores 10 and presses it down until the suction plate 147 contacts the first row of high-frequency transformer cores 10. Then, the lower suction cylinder 142 pushes the magnet base plate 145 down, so that the magnet 146 contacts the suction plate 147 and attracts the first row of high-frequency transformer cores 10 onto the suction plate 147. After that, the upper suction cylinder 143 retracts its cylinder push rod, so that the suction base plate 141... 1. The high-frequency transformer cores 10 adsorbed on the suction plate 147 are moved upwards, and then the material transfer cylinder 15 drives the suction mechanism 14 to move to the right, so that the high-frequency transformer cores 10 adsorbed on the suction plate 147 are moved directly above the conveyor belt 2. At this time, the upper suction cylinder 143 pushes the suction base plate 141 down and lowers the high-frequency transformer cores 10 adsorbed on the suction plate 147 onto the conveyor belt 2. Then, the lower suction cylinder 142 retracts its cylinder push rod, so that the magnet 146 returns to its position, which reduces the magnetic force at the suction plate 147. After that, the upper suction cylinder 143 retracts its cylinder push rod, so that the cores 10 are detached from the suction plate 147 and remain on the conveyor belt 2. Then, the blocking cylinder 53 pushes the blocking plate 56 down to contact the discharge table 57.

[0072] Step 4: Shifting the first row of magnetic cores

[0073] After the material straightening mechanism 13 straightens a row of high-frequency transformer cores 10 that have moved from the self-feeding seat 18 to the conveyor belt 2 (specifically, the material straightening plate 132 and the scale 133 are used to align the row of high-frequency transformer cores 10 remaining on the conveyor belt 2 and align them with the starting point of the working position of the transfer device 3), the conveyor belt 2 transports this row of high-frequency transformer cores 10 to the end until the high-frequency transformer core 10 closest to the end of the conveyor belt 2 reaches the end of the conveyor belt 2 and the transport stops (the conveyor belt 2 stops transporting according to the detection signal of the arrival of the high-frequency transformer core 10 by the through-beam sensor located at the end of the conveyor belt 2).

[0074] Step 5 Single magnetic core transfer

[0075] At the starting point of the working position of the transfer device 3, the clamping cylinder 31 pushes the clamping mechanism 37 down along the transfer vertical slide rail 38 and clamps a corresponding high-frequency transformer core 10 at the end of the conveyor belt 2. Then, the clamping cylinder 31 retracts its cylinder push rod, causing the clamping mechanism 37 to drive the high-frequency transformer core 10 up (rebound). Then, the synchronous belt mechanism 32 drives the clamping cylinder 31 to move along the transfer horizontal slide rail 36 with the moving block 39, so that the clamping mechanism 37 and the high-frequency transformer core 10 it clamps move to the right side of the conveyor belt 2. When the dispensing device 4 moves to the end point of the working position of the transfer device 3, the clamping cylinder 31 pushes the clamping mechanism 37 down along the transfer vertical slide rail 38 from directly above the positioning mechanism 47 of the dispensing device 4, and the clamping mechanism 37 releases the high-frequency transformer core 10 it is holding, thereby placing the high-frequency transformer core 10 on the positioning mechanism 47 of the dispensing device 4; then the clamping mechanism 37 rises (returns) and returns to the starting point of the working position of the transfer device 3 with the clamping cylinder 31, thereby resetting the transfer device 3;

[0076] Step 6: Apply adhesive to each magnetic core.

[0077] The high-frequency transformer core 10 is clamped by the pneumatic fingers used for positioning a single high-frequency transformer core, and the position of the high-frequency transformer core 10 on the positioning mechanism 47 (specifically the upper positioning block 472) is adjusted (i.e., the high-frequency transformer core 10 is clamped in a direction orthogonal to the clamping direction of the clamping mechanism 37 and then immediately released, so that the placement orientation of the high-frequency transformer core 10 on the upper positioning block 472 is consistent with its placement orientation in the feeding seat 18); then the glue scraping cylinder 43 drives the glue scraping mechanism 42 to scrape out a certain thickness of glue layer in the glue pool 45 (i.e., the left glue scraping plate 424 or the right glue scraping plate 425 performs one glue scraping), and then the glue sticking motor 46 starts from the initial position (meaning that the two finger-shaped clamping rods of the glue sticking mechanism 48 are arranged vertically in their independent cylinders). The adhesive motor 46 rotates 90° clockwise, causing the adhesive mechanism 48 to swing to the positioning mechanism 47 and clamp the high-frequency transformer core 10 (the two finger-shaped clamping rods of the adhesive mechanism 48 can clamp the outer walls of the left and right side pillars of the high-frequency transformer core horizontally at the lower part of the high-frequency transformer core; that is, the adhesive mechanism 48 clamps the high-frequency transformer core placed at the top of the upper positioning block 472); then the adhesive motor 46 reverses 180°, causing the high-frequency transformer core 10 clamped by the adhesive mechanism 48 to swing to the glue pool 45 and face the glue layer. At this time, the adhesive mechanism 48 releases the high-frequency transformer core 10, so that the end faces of its two side pillars contact the glue layer; then the adhesive motor 46 rotates 90° clockwise to reset (i.e., return to the initial position).

[0078] Step 7: Single magnetic core unloading

[0079] The discharge motor 52 rotates 90° clockwise from its initial position (referring to the phase of the main shaft of the discharge motor 52 that enables the two finger-shaped clamping rods of the discharge mechanism 51 to be vertically arranged on its independent cylinder), causing the discharge mechanism 51 to swing into the glue tank 45 and clamp the high-frequency transformer core 10. (The two finger-shaped clamping rods of the discharge mechanism 51 can clamp only the outer wall surfaces of the left and right side pillars of the high-frequency transformer core 10 horizontally at the upper part; that is, the discharge mechanism 51 completes the clamping of the high-frequency transformer core after glue dispensing by clamping the part of the high-frequency transformer core remaining in the glue tank 45 that is far from the glue layer.) Then, the discharge motor 52 reverses 180°, causing the high-frequency transformer core 10 after dispensing, held by the discharge mechanism 51, to swing to the discharge platform 57. At this time, the discharge mechanism 51 releases the high-frequency transformer core 10, allowing it to stop in the receiving area. Then, the discharge motor 52 rotates 90° forward to reset (i.e., returns to the initial position). Then, the left and right push cylinders 58 push the left and right straight push plates 59 into the discharge platform 57, pushing the high-frequency transformer core 10 after dispensing, which is stopped in the receiving area, to the right. Then, the left and right push cylinders 58 retract their cylinder push rods, causing the left and right straight push plates 59 to return to their original positions.

[0080] Step 8: Displacement of the remaining magnetic core

[0081] Conveyor belt 2 continues to transport the remaining high-frequency transformer cores 10 to the end until the high-frequency transformer core 10 closest to the end of conveyor belt 2 reaches the end of conveyor belt 2 and the transport stops.

[0082] Step 9 Repeat steps 5 to 8 until the row of high-frequency transformer cores 10 that have moved from the self-feeding seat 18 to the conveyor belt 2 have been processed one by one (i.e., one by one the material is discharged). At this time, the left and right push proximity sensors 572 are triggered and generate a signal to control the rise of the material blocking plate 56.

[0083] Step 10: First row of magnetic cores discharged

[0084] The material blocking cylinder 53 drives the material blocking plate 56 to rise, and then the front and rear pushing cylinders 54 push the front and rear horizontal pushing plates 50 into the discharge platform 57, and push the row of high-frequency transformer cores 10 that have been glued and are located on the right side of the receiving area forward as a whole until they pass over the material blocking plate 56 from below. Then the front and rear pushing cylinders 54 retract their cylinder push rods, so that the front and rear horizontal pushing plates 50 return to their original positions.

[0085] Step 11: Discharge of the first tray of magnetic cores

[0086] Repeat steps 3 to 10 until each row of high-frequency transformer cores 10 in the feeding seat 18 has been processed. Then the feeding plate 121 returns (as the feeding plate 121 continues to move to the right along the feeding seat 18, the probe 125 of the slot sensor enters the slot 126 located on the left side of the working position of the feeding device 1, and the triggered signal causes the feeding plate 121 to return). The equipment issues an alarm (triggered by the front and rear push proximity sensor 571), thereby reminding the operator to remove the high-frequency transformer cores 10 that have been glued from the feeding table 57.

[0087] Step 12 Continuous Operation

[0088] Repeat steps 2 to 11 to continue placing the high-frequency transformer core 10 in the feeding seat 18 (for example, replacing the second and third high-frequency transformer cores in the feeding seat 18, etc.) until all the high-frequency transformer cores 10 in the same batch have been processed.

[0089] Step 13 Shutdown and Maintenance

[0090] Click "Stop" on controller 6 to turn off the power and gas supply, and clean the equipment.

[0091] Example 2

[0092] To shorten operation time and improve production efficiency, Example 2 differs from Example 1 in the following ways:

[0093] Before magnet 146 returns to its original position (and ensuring the bottom of pressure plate 191 is above scale 133), the material balancing plate 132, pushed by material balancing cylinder 131, moves to the right between conveyor belt 2 and the bottom of suction plate 147, and pushes a row of high-frequency transformer cores adsorbed on the bottom of suction plate 147. Thus, with the cooperation of material balancing plate 132, unloading is completed through corresponding operations on magnet 146. The process of material balancing plate 132 moving to the left as material balancing cylinder 131 retracts its cylinder push rod can be performed after unloading. Simultaneously, conveyor belt 2 is started until the first high-frequency transformer core arranged from back to front on conveyor belt 2 reaches the end of conveyor belt 2, at which point conveyor belt 2 stops.

[0094] Example 3

[0095] To shorten operation time and improve production efficiency, Example 3 differs from Example 1 in the following ways:

[0096] After the adhesive motor 46 drives the adhesive mechanism 48 to reverse the high-frequency transformer core 10 held at the self-positioning mechanism 47 (and before it moves and flips to be close to the glue pool 45), the left scraper 424 or the right scraper 425 scrapes the glue once.

[0097] Example 4

[0098] To shorten operation time and improve production efficiency, Example 4 differs from Example 1 in the following ways:

[0099] See Figure 4C As the clamping mechanism 37 begins to rise under the drive of the clamping cylinder 31, on the one hand, by controlling the start and stop of the conveyor belt 2, the first high-frequency transformer core currently arranged at the front of the end of the conveyor belt 2 is transported to the end of the conveyor belt 2 and waits for material to be picked up (specifically, waiting for the clamping mechanism 37 to return to the starting point of the working position of the transfer device 3 and descend to a position where the clamping mechanism 37 can clamp the high-frequency transformer core). On the other hand, the adhesive motor 46 first rotates 90° clockwise from its initial position (during which the placement orientation of the high-frequency transformer core on the positioning mechanism is adjusted), so that the two finger-shaped clamps of the adhesive mechanism 48 can grip the high-frequency transformer core. The rod swings to the top of the upper positioning block 472 and clamps the high-frequency transformer core 10 placed at the top of the upper positioning block 472. Then, the adhesive motor 46 reverses 180° to swing the high-frequency transformer core 10 clamped by the adhesive mechanism 48 to directly above the working position of the dispensing device 4 and releases the high-frequency transformer core 10. After that, the adhesive motor 46 returns to its initial position by rotating 90° forward again, so that the adhesive mechanism 48 can continue to perform dispensing operations on the next high-frequency transformer core transferred to the positioning mechanism 47 (i.e., the high-frequency transformer core waiting to be picked up).

[0100] Example 5

[0101] To shorten operation time and improve production efficiency, Example 5 differs from Example 1 in the following ways:

[0102] When the adhesive mechanism 48 has released the high-frequency transformer core 10 it was holding (which remains in the glue pool 45) directly above the working position of the dispensing device 4 and begins to return to the initial position with the adhesive motor 46, the discharge motor 52 first rotates 90° clockwise from the initial position, causing the two finger-shaped clamping rods of the discharge mechanism 51 to swing to the glue pool 45. The discharge mechanism 51 then holds the high-frequency transformer core 10 in the glue pool 45 after dispensing. At this time, the discharge motor 52 can swing the high-frequency transformer core 10 held by the discharge mechanism 51 to the receiving area by reversing 180°. After that, the discharge motor 52 returns to its initial position by rotating 90° clockwise again. At this time, the discharge mechanism 51 can continue to move the next high-frequency transformer core 10 remaining in the glue pool 45 (see embodiment 4), and push out the previous high-frequency transformer core 10 placed in the receiving area by the left and right push plates 59.

[0103] Example 6

[0104] To shorten operation time and improve production efficiency, Example 6 differs from Example 1 in the following ways:

[0105] When the high-frequency transformer core closest to the beginning of the conveyor belt 2 from the feeding seat 18 is transferred to the positioning mechanism 47, there are no more high-frequency transformer cores on the conveyor belt 2 (detected and determined by the through-beam sensor located at the end of the conveyor belt 2). The adhesive motor 46 and the discharge motor 52 will return to their respective initial positions after the adhesive mechanism 48 and the discharge mechanism 51 complete the dispensing and discharge of the high-frequency transformer core 10 (see embodiments 3, 4, and 5). At this time, as... The left and right push plates 59 push out the high-frequency transformer cores 10 from the receiving area. The discharge plate 121 pushes the high-frequency transformer cores that were originally in the last row in the discharge seat 18 to the working position of the feeding device 1. Then, the suction mechanism 14 loads a row of high-frequency transformer cores that have been pushed to the working position of the feeding device 1 and then unloads them onto the conveyor belt 2. Before the loading and unloading of this row of high-frequency transformer cores is completed, the blocking plate 56 rises and completes the unloading operation of a row of high-frequency transformer cores from the discharge seat 18 that has undergone the glue dispensing operation.

[0106] Example 7

[0107] To improve the effectiveness of the pressing mechanism 19 in the material loading process of the suction mechanism 14 (it was found during the trial run of the dispensing machine prototype of Example 1 that, due to the strong magnetic attraction of the magnet 146, the pressing plate 191 sometimes cannot completely block the high-frequency transformer cores of the next row, and some high-frequency transformer cores may still be attracted to the suction plate 147), the difference between Example 7 and Example 1 is as follows:

[0108] The pressure block 194 is movably mounted on two parallel and upward-pointing pressure bolts 196 fixed to the bottom of the pressure base plate 192 (which is U-shaped) through two through holes penetrating its upper and lower ends. The lower end of the pressure block 194 directly contacts the inner bottom surface of the pressure base plate 192. The lower end of the pressure spring 195 fitted on each pressure bolt 196 contacts the upper end of the pressure block 194, while the upper ends of the two pressure springs 195 are locked by the pressure nut 193 (i.e., the two pressure springs 195 are directly pre-pressed by the pressure nut 193). By interchangering the mounting positions of the pressure springs 195 and the pressure block 194 on the pressure bolts 196 (relative to embodiment 1), it is ensured that the pressure mechanism 19 can completely block the next row of high-frequency transformer cores during the loading process of the suction mechanism 14.

[0109] In summary, the high-frequency transformer core edge column dispensing machine provided by this invention adopts a whole-disk core loading and unloading operation method, which is highly adaptable to cores of different specifications, with stable and reliable dispensing quality and high yield. In addition, the machine has a high degree of automation, a compact working area, and a small footprint, and can maintain efficient operation for a long time. It significantly reduces manual labor and effectively lowers the intensity of manual labor. It can provide important technical support and equipment guarantee for the development of high-frequency transformer related industries, thereby improving the overall economic benefits of the industry.
