Description

Technical Field

[0001] The invention relates to pretreatment of a magnetic core of a high-frequency transformer, and in particular to automated rapid operation equipment for glue dispensing on side posts of a magnetic core. Background Art

[0002] High-frequency transformers are power transformers with operating frequencies exceeding medium frequency (10kHz) and are the main working parts in switching and inverter power supplies. Most high-frequency transformers have three cores in their cores, the middle core is called the middle core, and the cores on both sides are called side cores. The glue dispensing process of high-frequency transformers refers to applying, spraying, dripping or filling electronic glue onto the core of the core to fix, bond, insulate or smooth the surface of the electronic components of the high-frequency transformer. The glue dispensing of the side cores is performed on the end faces of the side cores. In the large-scale production of high-frequency transformers, a stable and reliable glue dispensing process and results of the side cores will largely determine the effectiveness of the core assembly and the consistency of the inductance effect (that is, the electronic glue applied on the end faces of the side cores can ensure that the two cores that have been aligned and bonded in the subsequent process have good overall magnetic conductivity).

[0003] Since the cores of different high-frequency transformers may have side columns of different shapes, the glue dispensing of the side columns of the cores in production is still mainly done manually. However, the glue dispensing process of the side columns of the cores is cumbersome (especially when the end faces of the side columns of the cores have irregular edges such as concave arcs), which at least includes the processes of flat-plate glue coating, roller flattening, core inversion, and extrusion coating. In addition, the manual operation is inefficient and has poor consistency, which has become a common key technology that urgently needs to be improved for industrial development.

[0004] At present, only a small number of high-frequency transformers with extremely large production volumes use dispensing valves, scraping meshes and other methods to perform auxiliary dispensing operations on the core side columns. For example, the scraper machine that can control the glue amount on the transformer core side columns proposed in Chinese patent CN212069367U meets the dispensing process requirements of various core side columns through scraping meshes and opening positions, but the scraping meshes are prone to different glue amounts and leaks. To this end, in Chinese patent CN212732820U, by using a glue coating carrier and a carrier driving assembly, the magnetic cores arranged on the transfer plate can be uniformly subjected to the processes of glue dispensing (extrusion coating), UV curing (to improve the reliability of glue coating) and material collection. However, the carrier driving assembly moves in each station in sequence, and the corresponding station (such as the glue tank) is in an idle waiting state after completing one operation, resulting in low overall efficiency. In addition, the magnetic cores are easily adhered to each other after being coated with glue and UV cured, which is not conducive to integration with subsequent production operations. In Chinese patent CN118098804A, the positioning blocks in each fixture, the scraper above and the lifting assembly below can be used to improve the bonding quality of magnetic chips of the same specification, and the adhesion of the magnetic cores can be avoided by setting up multiple fixtures. However, manual operation is required to fix the magnetic chips before glue dispensing and check the glue dispensing effect (and remove the magnetic cores). In addition, Chinese patent CN115430785A introduces multiple clamping cylinders (i.e., pneumatic clamps) for clamping / releasing products, thereby achieving the movement of products in and out of the dispensing seat. However, since dispensing is only performed when the dispensing seat moves to the dispenser position, the dispensing operation is not performed continuously. Summary of the invention

[0018] Preferably, the discharging device also includes a straight push plate for rearranging the high-frequency transformer cores (whose side column end faces have been glued by pressing them onto the glue layer) moved to the discharging table in sequence along the same direction (for example, perpendicular to the incoming material direction) in the discharging table (for example, rotating the high-frequency transformer cores in a whole row in the discharging seat 90 degrees according to their respective arrangement directions and then arranging them closely) and a horizontal push plate for moving the high-frequency transformer cores rearranged by the straight push plate out along another direction (for example, perpendicular to the above-mentioned rearrangement direction) in the discharging table. The straight push plate and the horizontal push plate are correspondingly connected to push cylinders respectively arranged in corresponding directions on the outside of the discharging table.

[0019] Preferably, the discharging device also includes a material blocking plate for separating the discharging table (for example, separating the discharging table in the moving-out direction of the rearranged high-frequency transformer core, so that the high-frequency transformer core moved to the discharging table is rearranged on one side of the material blocking plate and reaches the other side of the material blocking plate when moving out) and a material blocking cylinder arranged above the discharging table, and the material blocking plate is connected to the material blocking cylinder.

[0024] Furthermore, the clamping mechanism, gluing mechanism and discharging mechanism of the present invention adopt a clamping claw design, which can be applicable to the core side column gluing operation needs of high-frequency transformer cores of various specifications and models such as can type, RM type, E type, EC type, ETD type, EER type, PQ type, EP type, etc.

[0025] Furthermore, the present invention, based on the miniaturization of the glue pool (since the high-frequency transformer cores are glued one by one in the glue pool), combines glue pool temperature control and replacement of different glue scraping stations (specifically, different glue groove depths, that is, different glue layer thicknesses) for glue scraping. This can not only ensure the controllability of the glue thickness coated on the end faces of the side columns of the high-frequency transformer core (thereby meeting the requirements of different core side column glue dispensing processes), but also allow the equipment (mainly referring to the glue dispensing device, etc.) to better maintain an efficient operating state. Furthermore, based on the modular design of the whole machine, the present invention can also use the spindle phase of the viscose motor and the discharging motor to install and debug the equipment, thereby effectively improving the operating efficiency of the whole machine in production and ensuring the high efficiency and rapidity of use, operation and maintenance.

The inner side surface of the bottom of the plate 192 is in contact; there are two pressing nuts 193, which are respectively installed on a corresponding pressing bolt 196 through threaded cooperation to lock the pressing block 194 (specifically, to limit the upward movement of the pressing block 194); a strip-shaped mounting hole is opened on the upper part of the pressing piece 191 (made of aluminum AL6061), and the pressing piece 191 can be fixed on the left end surface of the pressing block 194 by means of a screw inserted into the mounting hole (and the installation height of the pressing piece 191 can be adjusted before fixing), and the bottom of the pressing piece 191 is an "L" shape bent to the right, and the assembly position of the bottom in the vertical direction is lower than the bottom of the suction piece 147 (that is, there is a height difference, see Figure 2D The material pressing bottom plate 192 is located on the left side of the material suction sheet 147 and is fixed at the same position as the material suction sheet 147 on the left end surface of the material suction bottom plate 141, so that the assembly position of the bottom of the material pressing sheet 191 in the horizontal direction is located on the left side of the bottom of the material suction sheet 147 (that is, the bottom of the material pressing sheet 191 and the bottom of the material suction sheet 147 are adjacent to each other in the horizontal direction and do not overlap each other, see Figure 2D ).

[0035] like Figure 2D and Figure 2EAs shown, when the upper suction cylinder 143 moves to the left to above the working position of the feeding device 1 under the drive of the material transfer cylinder 15, loading begins. Specifically, the upper suction cylinder 143 drives the suction bottom plate 141 to lower its height, so that before the bottom of the suction sheet 147 contacts a row of high-frequency transformer cores located at the working position of the feeding device 1, the bottom of the pressing sheet 191 first contacts another row of high-frequency transformer cores located on the left side of this row of high-frequency transformer cores (that is, the second row of high-frequency transformer cores arranged from right to left in the discharge seat 18). As the suction bottom plate 141 continues to lower its height, the height difference between the bottom of the pressing sheet 191 and the bottom of the suction sheet 147 gradually decreases as the pressing spring 195 is compressed (that is, the bottom of the suction sheet 147 is closer to the working position). The distance between a row of high-frequency transformer cores at the working position of the feeding device 1 gradually becomes smaller, and the compression of the pressure spring 195 reduces the pressure at the bottom of the pressure sheet 191, thereby avoiding damage to the row of high-frequency transformer cores contacted by the bottom of the pressure sheet 191. For this reason, 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 sheet 191 and the bottom of the suction sheet 147) until the bottom of the suction sheet 147 contacts the row of high-frequency transformer cores at the working position of the feeding device 1, and then the loading can be completed by corresponding operations on the magnet 146 on the magnet bottom plate 145 (because the function of the pressure sheet 191 is to press down the rear row of high-frequency transformer cores, it is ensured that only one row of high-frequency transformer cores is sucked up during feeding). Before starting to unload, it is necessary to first drive the loaded row of high-frequency transformer cores through the upper suction cylinder 143 and raise them to the original height along with the suction bottom plate 141. During this process, the bottom of the pressing piece 191 no longer contacts the high-frequency transformer cores in the discharge seat 18, and the pressing spring 195 is restored (that is, the height difference between the bottom of the pressing piece 191 and the bottom of the suction piece 147 is restored to the initial state when the assembly is completed), and then move to the right to above the conveyor belt 2 under the drive of the material moving cylinder 15 and start unloading. Specifically, the upper suction cylinder 143 drives the suction bottom 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, and then the unloading can be completed by corresponding operations on the magnet 146 on the magnet bottom plate 145. After that, the suction bottom plate 141 is raised, and the above operation can be repeated to load and unload again, so that at a certain time interval (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 through the whole row loading and unloading for the transfer device 3 to pick up the materials.

[0036] See also Figure 3The transfer device 3 includes a clamping cylinder 31, a transfer motor 33, a transfer column 34, a transfer casing 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 workbench 7 (see Figure 1A ), the transfer casing 36 is installed on two transfer columns 34, and the transfer casing 36 is equipped with a parallel synchronous belt mechanism 32 and a transfer horizontal slide rail 35; the transfer motor 33 is installed on the right side of the bottom of the transfer casing 36, and the main shaft of the transfer motor 33 is coaxially connected with the synchronous belt pulley on the corresponding side of the synchronous belt mechanism 32; the moving block 39 is assembled on the transfer horizontal slide rail 35, and the rear end of the moving block 39 is connected to the synchronous belt of the synchronous belt mechanism 32; the clamping cylinder 31 and the transfer vertical slide rail 38 are installed on the front end of the moving block 39 from top to bottom, and the installation position protrudes from the front side of the transfer casing 36; the clamping mechanism 37 specifically adopts pneumatic fingers, and the pneumatic fingers It comprises an independent cylinder mounted on a transfer vertical slide rail 38, and under the drive of the independent cylinder, two finger-shaped clamping rods (made of aluminum AL6061) extending from one side (specifically the lower side) can be brought close to each other to clamp a single high-frequency transformer core (specifically, the outer wall surfaces of the left and right side columns of the high-frequency transformer core are clamped, and applicable high-frequency transformer core models include: tank type, RM type, E type, EC type, ETD type, EER type, PQ type, EP type, etc.). When the 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). When the transfer operation is performed, the gripping mechanism 37 can follow the moving block 39 to the farthest left position of the transfer casing 36 under the drive of the synchronous belt mechanism 32 as the starting point of the working position of the transfer device 3, and the gripping mechanism 37 can follow the moving block 39 to the farthest right position of the transfer casing 36 under the drive of the synchronous belt mechanism 32 as the end point of the working position of the transfer device 3, that is, the gripping mechanism 37 without clamping the high-frequency transformer core and the gripping mechanism 37 with clamping the high-frequency transformer core are both controlled by controlling the transfer motor 33 and in the synchronous belt mechanism 32. Driven by the step belt mechanism 32, transfer is realized between the starting point and the end point of the working position of the transfer device 3, wherein the clamping mechanism 37 is driven by the clamping cylinder 31 to complete the change of state from unclamped to clamped during the descent / recovery at the starting point of the working position of the transfer device 3, and to complete the change of state from clamped to unclamped during the descent / recovery at the end point of the working position of the transfer device 3 (that is, the clamping mechanism 37 is used to pick up the high-frequency transformer core transported by the conveyor belt 2 and staying at the end of the conveyor belt 2 in turn).

[0037] See also Figure 4AThe glue dispensing device 4 is mainly composed of a glue scraping stand 41, a glue scraping mechanism 42, a glue scraping cylinder 43, a glue scraping transverse slide rail 44, a glue pool 45, a glue motor 46, a positioning mechanism 47 and a glue mechanism 48; the glue scraping stand 41 is fixed on the workbench 7 and is located at the right rear side of the suction stand 17 (see Figure 1A ); The glue scraping transverse slide rail 44 and the glue scraping cylinder 43 are arranged on the glue scraping stand 41 from left to right in sequence; the glue scraping mechanism 42 is arranged 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 pool 45 is fixed on the workbench 7 and is located below the glue scraping mechanism 42; the positioning mechanism 47 is installed on the rear side of the glue pool 45 and is located below the end point of the working position of the transfer device 3; the gluing motor 46 is fixed on the workbench 7, and the gluing mechanism 48 is connected to the positioning mechanism 47 extending between the glue pool 45 and the glue pool 45. The gluing mechanism 48 is connected to the main shaft of the gluing motor 46, wherein the gluing mechanism 48 specifically adopts pneumatic fingers, and the gluing mechanism 48 is fixed to the main shaft of the gluing motor 46 through the independent cylinder contained therein, so that as the gluing motor 46 (specifically its main shaft) rotates forward and reverse, 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 gluing mechanism 48, until the end faces of the two side columns of the high-frequency transformer core are opposite to the glue pool 45.

[0038] Combination Figure 4BAs shown, the positioning mechanism 47 includes a positioning groove opened on the workbench 7, an upper positioning block 472 installed at the middle position of the positioning groove and a pneumatic finger for positioning a single high-frequency transformer core; a lower positioning plate 471 fixed in the frame 8 is provided below the positioning groove, and the independent cylinder contained in the pneumatic finger for positioning the single high-frequency transformer core is fixed on the lower positioning plate 471. The pneumatic finger is different from the above-mentioned clamping mechanism 37 and the gluing mechanism 48 mainly in the shape of the clamping rod contained in each of them, that is: the pneumatic finger for positioning the single high-frequency transformer core The pneumatic fingers contain two inverted "L"-shaped clamping rods 473 (made of aluminum AL6061), and penetrate 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 to the opposite side of the inverted "L"-shaped clamping rod 473 and then wrapped around the outside of the top of the upper positioning block 472, so that the corresponding side outer wall surfaces of the two side columns of a high-frequency transformer core can be clamped along the direction orthogonal to the clamping direction of the two finger-shaped clamping rods of the clamping mechanism 37. When the clamping mechanism 37 drops to the lowest point driven by the clamping cylinder 31, the high-frequency transformer core it clamps can be released and placed on the top of the upper positioning block 472, thereby ensuring that the high-frequency transformer core maintains the same orientation (i.e., the end surface of the core side column faces upward) after completing loading, unloading and transfer operations with a row of high-frequency transformer cores in the discharge seat 18; the pneumatic fingers 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.

[0039] See also Figure 4D The scraper mechanism 42 includes a scraper bottom plate 421, a left scraper plate 424, a right scraper plate 425, a buffer valve 426 and a scraper switching cylinder 427; the scraper switching cylinder 427 is fixed at the middle position on the scraper bottom plate 421, and the scraper bottom plate 421 is provided with two cylinder push rods for the scraper switching cylinder 427 to penetrate downward through the scraper bottom plate 421, and the cylinder push rod of the scraper cylinder 43 is fixed at the right edge of the scraper bottom plate 421, and the scraper bottom plate 421 is connected to the scraper transverse slide rail 44, so that the scraper switching cylinder 427 can slide left and right in the scraper stand 41 (that is, the scraper switching cylinder 427 is assembled on the scraper transverse slide rail 44 through the scraper bottom plate 421, see details Figure 4A The left and right scraper plates 424 and 425 are arranged at intervals below the scraper bottom plate 421 and in the area directly opposite to the glue pool 45. The outer sides of the left and right scraper plates 424 and 425 (the outer sides refer to the sides opposite to the scraping directions of the left and right scraper plates 424 and 425, i.e., the right side of the left scraper plate 424 and the left side of the right scraper plate 425, see Figure 4A) are respectively provided with scraper support plates 422 connected to the scraper bottom plate 421, the left scraper plate 424 is respectively connected to one of the cylinder push rods of the scraper switching cylinder 427 (close to the right edge of the scraper bottom plate 421) and the scraper vertical slide rail 423 fixed on the outer scraper support plate 422, and the right scraper plate 425 is respectively connected to the other cylinder push rod of the scraper switching cylinder 427 (close to the left edge of the scraper bottom plate 421) and the scraper vertical slide rail 423 fixed on the outer scraper support plate 422, so that the left scraper plate 424 connected to the scraper switching cylinder 427 can be driven by the scraper cylinder 43. The right scraper plate 425 alternately completes the scraping operation at the glue pool 45 below (when the scraper plate switching cylinder 427 is ready to slide out to the left, the scraper plate switching cylinder 427 makes the right scraper plate 425 retract upward and the left scraper plate 424 release downward, that is, when the scraper plate switching cylinder 427 slides to the left, the left scraper plate 424 is used to scrape glue in the glue pool 45; when the scraper plate switching cylinder 427 is ready to slide back to the right, the scraper plate switching cylinder 427 makes the right scraper plate 425 release downward and the left scraper plate 424 retract upward, that is, when the scraper plate switching cylinder 427 slides to the right, the right scraper plate 425 is used to scrape glue in the glue pool 45, see details Figure 4A ); The buffer valves 426 are respectively installed at the left and right corners of the scraper bottom plate 421 (the two buffer valves 426 installed at the left corner of the scraper bottom plate 421 are respectively opposite to the two left buffer baffles 40 fixed near the left end of the scraper horizontal slide rail 44 on the scraper stand 41, and the two buffer valves 426 installed at the right corner of the scraper bottom plate 421 are respectively opposite to the right buffer baffle 49 fixed to the right end of the scraper horizontal slide rail 44 on the scraper stand 41 and between the scraper cylinder 43, see Figure 4A ), thereby limiting the stroke of the scraper cylinder 43, so that the left scraper plate 424 and the right scraper plate 425 connected to the scraper switching cylinder 427 can use the buffering and deceleration effect of the buffer valve 426 after moving into place (to avoid the left scraper plate 424 and the right scraper plate 425 from colliding with the glue pool 45) to ensure the scraping effect and make the scraped glue layer thickness consistent.

[0040] See also Figure 4E , Figure 4F and Figure 4GThe glue pool 45 includes a glue scraping box 451, a glue scraping table 452, a temperature sensor 453 and a heating tube 454; the glue scraping box 451 (made of aluminum AL6061, and the length × width × height dimensions of the glue scraping box 451 are designed according to the size of a single high-frequency transformer core, for example, 110mm × 50mm × 20mm) is provided with notches located at the upper edges of the corresponding sides and can be aligned with the top of the positioning mechanism 47 in front and back on the front and rear sides; the glue scraping table 452 includes a plate body (made of D2 steel) arranged in the glue scraping box 451, After the glue poured onto the glue scraping table 452 is scraped, a glue layer at a certain height above the workbench 7 can be formed in the glue scraping box 451, and serves as the working position of the glue dispensing device 4. The thickness of the glue layer is controlled by a notch (i.e., glue groove 4521, with a width of 17-30 mm) machined in the middle of the upper surface of the plate body (made of D2 steel) and running through the left and right sides. By replacing the glue scraping table 452 with different notch depths, glue layers of different thicknesses can be formed (after scraping, glue groove 4521 is distributed with glue of uniform thickness, and excess glue is located at The temperature sensor 453 and the heating tube 454 are installed under the glue scraping platform 452, wherein the temperature sensor 453 is fastened to the right side of the glue scraping box 451 through a nut, and the heating tube 454 is fastened to the right side of the glue scraping box 451 through its external fixing piece 455. The temperature sensor 453 and the heating tube 454 are connected to the controller 6 through a cable, so that the glue layer can be controlled to maintain a preset temperature so that the high-frequency transformer core 10 is at the end surface of its two side columns. After contacting the glue layer, a layer of glue can be quickly, appropriately and evenly coated (the high-frequency transformer core 10 swings from the positioning mechanism 47 on the rear side to the glue pool 45 on the front side along with the gluing mechanism 48, that is, when the gluing motor 46 reverses 180°, the side column end face located at the uppermost part of the high-frequency transformer core 10 flips over accordingly. At this time, as the gluing mechanism 48 releases the high-frequency transformer core 10 and starts to swing to the initial position, the corresponding high-frequency transformer core 10 that falls into the glue pool 45 will keep its side column end face in contact with the glue layer until it is moved again through the discharging operation).

[0041] See also Figure 5A and Figure 5B The discharging device 5 is mainly composed of a discharging mechanism 51, a discharging motor 52, a material blocking cylinder 53, a front and rear material pushing cylinder 54, a material blocking stand 55, a material blocking plate 56, a discharging platform 57 and a left and right material pushing cylinder 58; the material blocking stand 55 (made of aluminum AL6061) is fixed on the workbench 7 and is located on the right front side of the suction stand 17 (see Figure 1A); the discharging table 57 (made of aluminum AL6061) is installed on the workbench 7 and is located below the material blocking stand 55; the material blocking cylinder 53 is installed on the material blocking stand 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 so as to use the material blocking plate 56 to separate the discharging table 57 into two parts, front and rear (referred to as the front part of the discharging table 57 and the rear part of the discharging table 57 respectively); the left and right pushing cylinders 58 are located on the left side of the discharging table 57, and the front and rear pushing cylinders 54 are located on the rear side of the discharging table 57. The left and right pushing cylinders 58 and the front and rear pushing cylinders 54 are respectively connected to the workbench 7 through the supports fixed on the workbench 7; the discharging motor 52 is fixed on the workbench 7 in the area surrounded by the front and rear pushing cylinders 54, the glue pool 45 and the discharging table 57 (the left side of the area is the suction stand 17, see specifically Figure 1A The discharge mechanism 51 is connected to the main shaft of the discharge motor 52, wherein the discharge mechanism 51 specifically adopts pneumatic fingers, and the discharge mechanism 51 is fixed to the main shaft of the discharge motor 52 through the independent cylinder contained therein, so that the high-frequency transformer core 10 left in the glue pool 45 can be turned over and moved to the receiving area on the discharge table 57 (the area is located at the rear of the discharge table 57, near the left and right push rods) through the two finger-shaped clamping rods (made of aluminum AL6061) contained in the discharge mechanism 51. The material cylinder 58 can be aligned front to back with the notches on the top of the positioning mechanism 47 and the front and rear sides of the scraper box 451), that is, the discharging mechanism 51 releases a clamped high-frequency transformer core 10 when the two finger-shaped clamping rods it contains swing to the material receiving area, thereby placing the high-frequency transformer core 10 in the material receiving area (at this time, the high-frequency transformer core 10 from the discharge seat 18 completes loading, unloading, transfer and gluing operations with a row of high-frequency transformer cores and still maintains the same orientation and is coated with glue on the two uppermost side column end faces).

[0042] like Figure 5BAs shown, left and right straight push plates 59 (made of aluminum AL6061) are fixed on the cylinder push rods of the left and right pushing cylinders 58. The left and right straight push plates 59 can be translated from the left edge of the discharge platform 57 to the inside of the discharge platform 57 for a certain distance under the drive of the left and right pushing cylinders 58, and then return to the position before the translation, so that a high-frequency transformer core 10 placed in the material receiving area can be pushed out to the right (the blocking plate 56 after the downward movement can prevent the high-frequency transformer core 10 from being deflected during the pushing process) and wait for the next high-frequency transformer core 10 placed in the material receiving area to be pushed out; front and rear transverse push plates 50 (made of aluminum AL6061) are fixed on the cylinder push rods of the front and rear pushing cylinders 54. The front and rear transverse push plates 50 can be translated from the rear edge of the discharge platform 57 to the inside of the discharge platform 57 for a certain distance under the drive of the front and rear pushing cylinders 54 (the blocking plate 56 has completed the upward movement before the translation process). After the glue dispensing operation is completed, the blocking plate 56 moves downward again; the discharging table 57 can adopt inductive discharging (that is, front and rear push material proximity sensors 571 and left and right push material proximity sensors 572 are respectively arranged outside the right edge of the discharging table 57 at the front and rear parts of the discharging table 57, and the rear and rear parts of the discharging table 57 are respectively provided with front and rear push material proximity sensors 571 and left and right push material proximity sensors 572, see details for details). Figure 5A ).

[0043] The process of using the above high-frequency transformer core side column glue dispensing machine to automate and integrate high-frequency transformer core loading, material transfer, core side column glue dispensing, and finished product discharging is as follows: Step 1: Startup preparation Check the power supply of the equipment (powering the controller and each motor respectively) and the stability of the air source, adjust the clamping range of the clamping mechanism 37, the gluing mechanism 48 and the discharging mechanism 51 to match the size of the high-frequency transformer core, confirm the thickness of the glue layer at the glue pool 45 (specifically the depth of the notch of the scraper table 452) and the remaining glue, and click "Start" on the controller 6, and the equipment will start self-checking; Step 2: Start the work After determining that the unloading seat 18 is in an empty state (determined by the signal triggered by the probe 125 of the slot sensor after entering the slot seat 126 located on the left side of the unloading seat 18), the whole plate of high-frequency transformer core 10 after the inverted plate is placed in the unloading seat 18, and then the operating program in the controller 6 is started, and the equipment starts to run automatically after the glue temperature in the glue pool 45 reaches the preset temperature; Step 3 Loading the first row of magnetic cores 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, and then the material moving 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 bottom plate 141 down, so that the pressing mechanism 19 first contacts the second row of high-frequency transformer cores 10 and presses them tightly until the suction sheet 147 contacts the first row of high-frequency transformer cores 10; then the lower suction cylinder 142 pushes the magnet bottom plate 145 down, so that the magnet 146 contacts the suction sheet 147 and adsorbs the first row of high-frequency transformer cores 10 onto the suction sheet 147; then the upper suction cylinder 143 retracts its cylinder push rod to make the suction bottom plate 14 1 drives a row of high-frequency transformer cores 10 adsorbed on the material suction sheet 147 to move upward, and then the material transfer cylinder 15 drives the material suction mechanism 14 to move rightward, so that a row of high-frequency transformer cores 10 adsorbed on the material suction sheet 147 are moved to the top of the conveyor belt 2, at this time, the upper material suction cylinder 143 pushes the material suction bottom plate 141 to descend and lowers the row of high-frequency transformer cores 10 adsorbed on the material suction sheet 147 to the conveyor belt 2; then the lower material suction cylinder 142 retracts its cylinder push rod to return the magnet 146 to its position, resulting in a decrease in the magnetic force at the material suction sheet 147, and then the upper material suction cylinder 143 retracts its cylinder push rod to separate the cores 10 from the material suction sheet 147 and leave them on the conveyor belt 2; then the blocking cylinder 53 pushes the blocking plate 56 down to contact the discharge table 57; Step 4: Shift the first row of cores After the row of high-frequency transformer cores 10 moved from the unloading seat 18 to the conveyor belt 2 is sorted by the sorting mechanism 13 (specifically, the row of high-frequency transformer cores 10 remaining on the conveyor belt 2 is aligned front to back by the sorting plate 132 and the ruler 133, and aligned with the starting point of the working position of the transfer device 3), the conveyor belt 2 transports the 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 stops transporting (the conveyor belt 2 is controlled to stop transporting according to the detection signal of the arrival of the high-frequency transformer core 10 by the through-beam sensor provided at the end of the conveyor belt 2); Step 5: Single core transfer At the starting point of the working position of the transfer device 3, the clamping cylinder 31 pushes the clamping mechanism 37 to descend along the transfer vertical slide rail 38 and clamps a high-frequency transformer core 10 corresponding to the end of the conveyor belt 2. Then the clamping cylinder 31 retracts its cylinder push rod, so that the clamping mechanism 37 drives the high-frequency transformer core 10 to rise (recover), and 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 clamped by it move to the right side of the conveyor belt 2. The glue dispensing device 4 moves, and when it moves to the end point of the working position of the transfer device 3, the clamping cylinder 31 pushes the clamping mechanism 37 from the top of the positioning mechanism 47 of the glue dispensing device 4 to descend along the transfer vertical slide rail 38, and the clamping mechanism 37 releases the high-frequency transformer core 10 clamped by it, so that the high-frequency transformer core 10 is placed on the positioning mechanism 47 of the glue 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, so that the transfer device 3 is reset; Step 6: Glue a single magnetic core The position of the high-frequency transformer core 10 on the positioning mechanism 47 (specifically, the upper positioning block 472) is adjusted by clamping the high-frequency transformer core 10 with the pneumatic fingers for positioning a single high-frequency transformer core (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 released immediately, so that the placement position of the high-frequency transformer core 10 on the upper positioning block 472 is consistent with its placement position in the discharge seat 18); then the scraping cylinder 43 drives the scraping mechanism 42 to scrape out a certain thickness of glue layer in the glue pool 45 (i.e., the left scraping plate 424 or the right scraping plate 425 performs a scraping operation), and then the glue motor 46 is moved from the initial position (referring to the ability to vertically arrange the two finger-shaped clamping rods of the glue mechanism 48 on its independent cylinder) to the glue pool 45. The gluing motor 46 (the main shaft phase of the gluing motor 46 above) rotates forward 90°, so that the gluing mechanism 48 swings to the positioning mechanism 47 and clamps the high-frequency transformer core 10 (the two finger-shaped clamping rods of the gluing mechanism 48 can only clamp the outer wall surfaces of the left and right side columns of the high-frequency transformer core in the horizontal direction at the lower part of the high-frequency transformer core; that is, the gluing mechanism 48 completes the clamping of the high-frequency transformer core placed on the top of the upper positioning block 472); then the gluing motor 46 is reversed 180°, so that the high-frequency transformer core 10 clamped by the gluing mechanism 48 swings to the glue pool 45 and faces the glue layer, at which time the gluing mechanism 48 releases the high-frequency transformer core 10, so that the end surfaces of its two side columns contact the glue layer; then the gluing motor 46 rotates forward 90° to reset (that is, return to the initial position); Step 7 Single core removal The discharging motor 52 rotates forward 90° from the initial position (referring to the main shaft phase of the discharging motor 52 that enables the two finger-shaped clamping rods of the discharging mechanism 51 to be vertically arranged on its independent cylinder), so that the discharging mechanism 51 swings into the glue pool 45 and clamps the high-frequency transformer core 10 (the two finger-shaped clamping rods of the discharging mechanism 51 can only clamp the outer wall surfaces of the left and right side columns of the high-frequency transformer core 10 in the horizontal direction at the upper part of the high-frequency transformer core 10; that is, the discharging mechanism 51 completes the clamping of the high-frequency transformer core after the glue is dispensed by clamping the part of the high-frequency transformer core that is left in the glue pool 45 away from the glue layer. ); then the discharging motor 52 is reversed 180°, so that the high-frequency transformer core 10 after glue dispensing held by the discharging mechanism 51 swings to the discharging platform 57, at which time the discharging mechanism 51 releases the high-frequency transformer core 10, so that it stays in the material receiving area; then the discharging motor 52 is forward rotated 90° to reset (i.e., return to the initial position); then the left and right pushing cylinders 58 push the left and right straight push plates 59 into the discharging platform 57, and push the high-frequency transformer core 10 after glue dispensing staying in the material receiving area to the right, and then the left and right pushing cylinders 58 retract their cylinder push rods to return the left and right straight push plates 59 to their positions; Step 8 Remaining core shift The 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 the conveyor belt 2 reaches the end of the conveyor belt 2 and stops transporting; Step 9 Repeat steps 5 to 8 until the row of high-frequency transformer cores 10 that move from the unloading seat 18 to the conveyor belt 2 are processed one by one (i.e., the unloading is completed one by one), at which time the left and right pusher proximity sensors 572 are triggered and generate a signal to control the rise of the blocking plate 56; Step 10: Unloading the first row of magnetic cores The material blocking cylinder 53 drives the material blocking plate 56 to rise, and then the front and rear material pushing cylinders 54 push the front and rear horizontal push plates 50 into the material discharging platform 57, and push the row of high-frequency transformer cores 10 that have been glued and are on the right side of the material receiving area forward as a whole, until they pass over the material blocking plate 56 from below, and then the front and rear material pushing cylinders 54 retract their cylinder push rods to return the front and rear horizontal push plates 50 to their original positions; Step 11: First plate of magnetic cores removed Repeat steps 3 to 10 until each row of high-frequency transformer cores 10 in the discharge seat 18 is completed, and then the discharge plate 121 returns (as the discharge plate 121 continues to move to the right along the discharge seat 18, the probe 125 of the slot sensor enters the slot seat 126 located on the left side of the working position of the loading device 1, and the triggered signal causes the discharge plate 121 to return), and the device issues an alarm (the alarm signal is triggered by the front and rear pusher proximity sensors 571), thereby reminding the operator to remove the high-frequency transformer core 10 that has been glued on the discharge table 57; Step 12: Continuous operation Repeat steps 2 to 11 to continue placing the high-frequency transformer cores 10 in the unloading seat 18 (for example, replacing the second plate, the third plate of high-frequency transformer cores in the unloading seat 18, etc.), until all the high-frequency transformer cores 10 of the same batch are completed; Step 13: Stop and clean up Click "Stop" on controller 6 to turn off the power and gas supply, and clean the equipment.

[0044] Example 2 In order to shorten the operation time and improve the production efficiency, the difference between Example 2 and Example 1 is as follows: Before the magnet 146 returns to its original position (and ensure that the bottom of the pressing sheet 191 is above the scale 133), the material plate 132 moves rightward to between the conveyor belt 2 and the bottom of the material suction sheet 147 under the push of the material cylinder 131, and pushes a row of high-frequency transformer cores adsorbed on the bottom of the material suction sheet 147, so that the material plate 132 cooperates with the corresponding operation of the magnet 146 to complete the unloading. And the process of the material plate 132 moving leftward with the material cylinder 131 retracting its cylinder push rod can be carried out after the unloading is completed, and the conveyor belt 2 is started while the process is being carried out, until the first high-frequency transformer core arranged from the back to the front on the conveyor belt 2 reaches the end of the conveyor belt 2 and stops the conveyor belt 2.

[0045] Example 3 In order to shorten the operation time and improve the production efficiency, the difference between Example 3 and Example 1 is as follows: After the glue motor 46 drives the glue mechanism 48 to reverse the clamped high-frequency transformer core 10 from the positioning mechanism 47 (and before it moves and flips to near the top of the glue pool 45), the left scraper 424 or the right scraper 425 performs a scraping operation.

[0046] Example 4 In order to shorten the operation time and improve the production efficiency, the difference between Example 4 and Example 1 is as follows: See also Figure 4CAs the clamping mechanism 37 starts 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 in front of the end of the conveyor belt 2 is transported to the end of the conveyor belt 2 and waits for material collection (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 the clamping mechanism 37 can clamp the high-frequency transformer core), on the other hand, the glue motor 46 first rotates forward 90° from the initial position (in this process, the placement orientation of the high-frequency transformer core on the positioning mechanism is adjusted), so that the two finger clamps of the glue mechanism 48 The rod swings to the top of the upper positioning block 472 and completes the clamping of the high-frequency transformer core 10 placed on the top of the upper positioning block 472. Then the glue motor 46 reverses 180° to swing the high-frequency transformer core 10 clamped by the glue mechanism 48 to just above the working position of the glue dispensing device 4 and releases the high-frequency transformer core 10. Thereafter, the glue motor 46 returns to its initial position by rotating forward 90° again, so as to continue to perform glue dispensing operation on the next high-frequency transformer core (i.e., the high-frequency transformer core waiting for material collection) transferred to the positioning mechanism 47 through the glue mechanism 48. Example 5 In order to shorten the operation time and improve the production efficiency, the difference between Example 5 and Example 1 is as follows: When the glue mechanism 48 has released the high-frequency transformer core 10 (the core remains in the glue pool 45) it clamped just above the working position of the glue dispensing device 4 and begins to return to the initial position with the glue motor 46, the discharging motor 52 first rotates forward 90° from the initial position to swing the two finger-shaped clamping rods of the discharging mechanism 51 to the glue pool 45, and the discharging mechanism 51 clamps the high-frequency transformer core 10 after glue dispensing in the glue pool 45. At this time, the discharging motor 52 can swing the high-frequency transformer core 10 clamped by the discharging mechanism 51 to the material receiving area by reversing 180°; thereafter, the discharging motor 52 returns to its initial position by rotating forward 90° again, and at this time, the next high-frequency transformer core 10 remaining in the glue pool 45 can be moved by the discharging mechanism 51 (refer to Example 4), and the previous high-frequency transformer core 10 placed in the material receiving area can be pushed out by the left and right straight push plates 59.

[0047] Example 6 In order to shorten the operation time and improve the production efficiency, the difference between Example 6 and Example 1 is as follows: When the high-frequency transformer core closest to the starting end of the conveyor belt 2 in a row of high-frequency transformer cores from the unloading seat 18 on the conveyor belt 2 is transferred to the positioning mechanism 47, there is no high-frequency transformer core on the conveyor belt 2 at this time (detected and determined by the cross-beam sensor arranged at the end of the conveyor belt 2), the gluing motor 46 and the discharging motor 52 will return to their respective initial positions after the gluing mechanism 48 and the discharging mechanism 51 complete the dispensing and discharging of the high-frequency transformer core 10 (refer to Examples 3, 4 and 5). At this time, as The left and right straight push plates 59 push out the high-frequency transformer cores 10 in the material receiving area, and the discharge plate 121 pushes the high-frequency transformer cores originally in the back row in the discharge seat 18 to move to the working position of the loading device 1, and then the suction mechanism 14 pushes a row of high-frequency transformer cores pushed to the working position of the loading device 1 for loading and then unloading to the conveyor belt 2. Before the loading and unloading of this row of high-frequency transformer cores is completed, the material blocking plate 56 rises and completes the unloading operation of a row of high-frequency transformer cores from the discharge seat 18 that have undergone the glue dispensing operation.

[0048] Example 7 In order to improve the effect of the pressing mechanism 19 during the charging process of the suction mechanism 14 (it was found in the trial operation after the dispensing machine prototype of Example 1 was assembled that due to the strong magnetic attraction of the magnet 146, the pressing sheet 191 sometimes cannot completely block the high-frequency transformer cores in the rear row, and some of the high-frequency transformer cores may still be adsorbed on the suction sheet 147), the difference between Example 7 and Example 1 is as follows: The press block 194 is movably assembled on two press bolts 196 fixed on the bottom of the press base plate 192 (which is "U" shaped) and inserted upward into the inner side of the press base plate 192 through two through holes penetrating its upper and lower end surfaces, and the lower end of the press block 194 is directly in contact with the inner side of the bottom of the press base plate 192; the press spring 195 mounted on each press bolt 196 has its lower end in contact with the upper end of the press block 194, and the upper ends of the two press springs 195 are locked by the press nut 193 (that is, the two press springs 195 are directly pre-tightened appropriately by the press nut 193). By exchanging the assembly positions of the press spring 195 and the press block 194 on the press bolt 196 (relative to Example 1), it is ensured that the press mechanism 19 can completely block the high-frequency transformer cores in the next row during the process of the suction mechanism 14 loading the entire row of high-frequency transformer cores.
