DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] The mutual inductor in the present invention is a kind of power electronic components in the smart grid industry, wherein plastic encapsulation of the mutual inductor coil is a process in the production process of the mutual inductor and is a part of the manufacture of the mutual inductor.

[0021] Example 1: Refer to the attached specification Figure 1 A transformer coil plastic shell packaging device according to an embodiment of the present invention comprises a base 1, a mounting plate 2 and a discharge guide frame 13 are fixedly provided on the top of the base 1, a bearing seat 8 and an L-shaped frame 9 are fixedly provided on one end of the top of the mounting plate 2, an electric push rod 10 is installed inside the L-shaped frame 9, a lifting platform 11 is fixedly connected to the telescopic end of the electric push rod 10, and a conveying plate 12 for conveying the packaging shell is provided on the top of the bearing seat 8; The bottom end of the lifting platform 11 is provided with a gluing mechanism 4 for gluing the fastening surface of the packaging shell and a residual glue scraping mechanism 5 for cleaning the excess glue squeezed out during the crimping packaging process, and a lifting mechanism 6 is provided at the end of the top of the mounting plate 2 away from the bearing seat 8; A pushing and pressing mechanism 3 is provided between the bearing seat 8 and the lifting platform 11 for driving the conveying plate 12 to push the package shell and driving the ejecting mechanism 6 to eject the packaged finished product.

[0022] It should be noted that the present invention uses the electric push rod 10 to push the lifting platform 11 to reciprocate up and down, so that the pushing and pressing mechanism 3 that moves up and down synchronously with the lifting platform 11 intermittently pushes the shell to be packaged on the feeding plate 12 (see Fig.14 The actual shape of the product (in the image) flows in sequence between the gluing station, the residual glue scraping station and the finished product ejecting station to achieve continuous packaging processing and unloading.

[0023] Specifically, Figure 1-Figure 2 and Fig.10 As shown, the feed plate 12 is composed of a push bar, a loading bar and a connecting bar fixedly connecting the push bar and the loading bar, and is arranged in an I-shaped structure. An I-shaped groove adapted to the feed plate 12 is provided on the top of the bearing seat 8, wherein the portion of the I-shaped groove corresponding to the upper end of the push bar is a sealing setting to prevent the push bar from being dislocated during the passive pushing process. The feed plate 12 is movably arranged inside the I-shaped groove, and a slot and a supporting groove are respectively provided on the top of the push bar and the loading bar, wherein the inner bottom end of the supporting groove is arranged in a stepped structure, which can support the packaging shell without affecting the subsequent ejection mechanism 6 to eject the packaged finished transformer coil out of the supporting groove; Guide rods are fixedly provided at the four corners of the top of the bearing seat 8, and the top ends of the guide rods movably penetrate the lifting platform 11, wherein the setting of the guide rods can ensure that the lifting and lowering movement of the lifting platform 11 is limited.

[0024] It should be noted that the length of the push bar is greater than the length of the loading bar, and the push bar moves to the leftmost end under the action of the pushing and pressing mechanism 3 (refer to Figure 1 When the package shell that has been packaged at the rightmost end of the material carrying strip is in the position of the view direction (the following description of the left and right movement is all referred to this figure), the package shell that has been packaged at the rightmost end of the material carrying strip just moves to the finished product ejection station and is ejected from the supporting trough by the ejection mechanism 6 for unloading along the unloading guide frame 13.

[0025] Specifically, Figure 1-Figure 2 As shown, the pushing and pressing mechanism 3 includes two side ears 31 fixed on the outside of the lifting platform 11 and a guiding inclined seat 35 fixed on the outside of the bearing seat 8, wherein the upper half of the guiding inclined seat 35 is a right-angled trapezoidal structure, and the high point of the inclined surface on the guiding inclined seat 35 is flush with the lower end surface of the push bar, and a swing bar 32 is rotatably installed between the opposite sides of the two side ears 31 through a rotating rod, a limiting rod 33 is fixedly provided at the position of the swing bar 32 on the outside of the lifting platform 11, and a straight spring 34 is fixedly connected between the swing bar 32 and the lifting platform 11.

[0026] It should be noted that when the pendulum bar 32 is in the initial state (i.e. Figure 2 When the lifting platform 11 is in the state shown in the figure, the straight spring 1 34 is still in the stretched state. At this time, the lowest point of the swing bar 32 just corresponds to the slot at the corresponding position on the push bar. When the electric push rod 10 is used to push the lifting platform 11 to move downward, the swing bar 32 maintains the initial state and moves downward synchronously with the lifting platform 11. When the lower end of the swing bar 32 passes through the slot at the corresponding position and contacts the inclined surface on the guide inclined seat 35, as the lifting platform 11 continues to move downward, the lower end of the swing bar 32 will continue to move along the inclined surface, and use the inclined surface area on the guide inclined seat 35 to squeeze the lower end of the swing bar 32, so that the lower end of the swing bar 32 is axially swung away from the lifting platform 11 with the rotating rod at its upper end connected to the side ear 31 as the center, thereby pushing the push bar to move leftward. When the lower end of the swing bar 32 leaves the inclined area on the guiding inclined seat 35 and enters the vertical area, as the lifting platform 11 moves downward, it will squeeze the pressed part of the ejecting mechanism 6, causing the ejecting part of the ejecting mechanism 6 to move upward, ejecting the finished packaged product out of the supporting slot.

[0027] Specifically, Figure 4-Figure 6 As shown, the gluing mechanism 4 includes a containing groove 1 opened at the bottom of the lifting platform 11, and four embedded grooves 41 are opened inside the containing groove 1, and a vertical rod 44 is fixed inside each embedded groove 41. A cross square column 42 is slidably installed between the four embedded grooves 41, and the end of the cross square column 42 extends to the corresponding interior, and one end of the cross square column 42 extending to the interior is movably sleeved on the outside of the vertical rod 44, and a straight spring 2 45 is sleeved on the outside of the vertical rod 44, which is fixedly connected to the cross square column 42 and the top surface of the inner cavity of the embedded groove 41, wherein the setting of the vertical rod 44 can ensure that the straight spring 2 45 can only be compressed in the vertical direction; A sample frame 43 is fixedly sleeved on the outside of the cross square column 42, wherein the thickness of the sample frame 43 is equal to the thickness of the shell to be packaged, and movable plates 46 are slidably sleeved at the positions corresponding to each embedding groove 41 and located on the inside and outside of the sample frame 43 on the outside of the cross square column 42, wherein the setting of the cross square column 42 can ensure that the movable plate 46 can only move linearly along the horizontal direction, thereby ensuring the stability of the subsequent gluing process, and a square spring 410 is sleeved on the outside of the cross square column 42 and fixedly connected between the surfaces of the cross square column 42 at the corresponding positions of the movable plates 46, wherein the setting of the square spring 410 can ensure that the distance between the two movable plates 46 on the corresponding sides in the initial state is greater than the thickness of the sample frame 43, so that the shell to be packaged can smoothly enter between the two sets of movable plates 46 during the rising process, and each movable plate 46 is provided with a trapezoidal block 49 and a glue outlet assembly 48 at the top and bottom ends respectively, and a U-shaped guide frame 47 is fixedly provided at the position corresponding to the trapezoidal block 49 at the top of the inner cavity of the containing groove.

[0028] It should be noted that, in the process of gluing the pre-fastened (i.e., the upper shell is placed on the top of the lower shell with the coil installed to form a gap between the two) packaging shell, when the pre-fastened packaging shell placed in the material support slot on the material loading strip is pushed to the gluing station, as the lifting platform 11 moves downward, the pre-fastened packaging shell will enter the cavity surrounded by the inner and outer movable plates 46 of the sample frame 43. When the lower end surface of the movable plate 46 contacts the material loading strip, the glue outlet point of the glue outlet component 48 is exactly at the low point of the cavity surrounded by the inner and outer movable plates 46 of the sample frame 43. Then, as the lifting platform 11 continues to move downward, the loading bar will push the movable plate 46 upward, thereby pushing the cross square column 42 to squeeze the straight spring 2 45 along the direction of the vertical rod 44, and after the trapezoidal block 49 at the top of the movable plate 46 contacts the U-shaped guide frame 47, as the lifting platform 11 continues to move downward, the U-shaped guide frame 47 will push the trapezoidal blocks 49 at the top of the movable plates 46 inside and outside the sample frame 1 43 to move toward each other, thereby driving the two movable plates 46 at the corresponding positions to move toward each other, allowing the glue outlet point of the glue outlet component 48 to enter the cavity for gluing.

[0029] Specifically, Figure 7 As shown, the glue outlet assembly 48 includes a cavity 481 arranged at the bottom end of the movable plate 46 and a glue guide groove 482 opened at the bottom end of the inner side of the movable plate 46, a through groove 483 is provided between the cavity 481 and the glue guide groove 482, a pressure plate 484 is provided inside the cavity 481, and a liquid capsule 485 fixedly connected to the inner wall of the cavity 481 and a push rod 487 movably passing through the pressure plate 484 are respectively fixed on both sides of the pressure plate 484, a straight spring 486 is fixedly connected between the pressure plate 484 and the inner wall of the cavity 481, and a connecting hose 488 is provided between the liquid capsule 485 and the through groove 483.

[0030] It should be noted that a glue delivery pipe for replenishing glue is connected to the liquid capsule 485, and a one-way valve is installed on the glue delivery pipe and the connecting hose 488, which is used to realize automatic glue replenishment by utilizing the pressure change inside the liquid capsule 485 when the liquid capsule 485 is restored to its initial state after being pressurized. In the process of gluing the cavity surrounded by the inner and outer movable plates 46 of the sample frame 43 by using the glue discharge component 48, when the U-shaped guide frame 47 pushes the trapezoidal blocks 49 at the top of the inner and outer movable plates 46 of the sample frame 43 to move toward each other, it drives the corresponding position When the two movable plates 46 move towards each other, the pre-fastened upper shell will squeeze the push rod 487 into the cavity 481, thereby pushing the pressure plate 484 to squeeze the liquid capsule 485, allowing the glue inside the liquid capsule 485 to flow through the connecting hose 488 and the through groove 483 in turn, enter the glue guide groove 482, and flow along the glue guide groove 482 to the inside of the cavity, and then as the lifting platform 11 moves upward, the push rod 487 automatically resets under the action of the restoring force of the straight spring three 486, preventing the glue from continuing to flow out, and automatically replenishing the glue inside the corresponding liquid capsule 485.

[0031] Specifically, Figure 4 and Figure 8-Figure 9 As shown, the residual glue scraping mechanism 5 includes a second container groove opened at the bottom of the lifting platform 11, a cross cylinder 51 and a second sample frame 52 fixedly sleeved on the outside of the cross cylinder 51 are fixedly arranged inside the second container groove, wherein the thickness of the first sample frame 43 is also equal to the thickness of the shell to be packaged, and a scraping glue frame 53 is arranged on the outside of the cross cylinder 51 and on the inside and outside of the second sample frame 52, and a cross plate 56 is fixedly arranged on the top of the scraping glue frame 53, wherein when the lowest point of the scraping glue frame 53 contacts the upper end surface of the material loading strip, the scraping glue point on the scraping glue frame 53 is just below the gap formed when the upper shell is placed on the top of the lower shell equipped with the coil, and the scraping glue point always fits the corresponding side wall of the packaging shell for lifting, and the bottom end surface of the second sample frame 52 just contacts the upper end surface of the upper shell, and a straight spring four 57 is fixedly connected between the cross plate 56 and the top of the inner cavity of the second container groove; A guide groove 54 is provided through the middle of each scraper frame 53, and the end of the cross cylinder 51 movably passes through the guide groove 54 at the position, and the outer side of the cross cylinder 51 is fixedly sleeved with a limit ring 55 at the inner and outer sides of each scraper frame 53, wherein the outer diameter of the limit ring 55 is larger than the width of the guide groove 54, and the two corresponding limit rings 55 are arranged to move in contact with the surface of the scraper frame 53.

[0032] It should be noted that in the process of pressing and packaging the shell to be packaged after the glue is applied, when the lowest point of the glue scraping frame 53 contacts the upper end surface of the loading strip as the lifting platform 11 moves downward, as the lifting platform 11 continues to move downward, the sample frame 2 52 will apply pressure to the upper shell, so that it is completely pressed onto the lower shell to complete the packaging. In this process, as the upper shell gradually moves downward, the glue in the gap formed when the upper shell is placed on the top of the lower shell with the coil installed will be gradually squeezed to disperse it, thereby improving the bonding effect between the upper and lower shells, and the glue scraping frame 53 will push the cross plate 56 to squeeze the straight spring four 57 upward along the guide groove 54, and in the process of dispersing the glue, part of the glue will be squeezed out and flow downward along the outer wall of the lower shell into the collecting groove on the glue scraping frame 53, and then as the lifting platform 11 moves upward, the glue scraping frame 53 will synchronously move upward along the outer side of the packaging shell to scrape off the excess glue remaining on the surface of the packaging shell.

[0033] Specifically, Figure 1-Figure 2 and Figure 10-11 As shown, the ejecting mechanism 6 includes a seat block 61 fixed on the top of the mounting plate 2, a running channel is provided through a position corresponding to the I-shaped groove on one side of the seat block 61, wherein the portion of the running channel corresponding to the upper end of the push strip is also sealed to ensure the stability of the push strip during the pushing process, a sinking groove 62 is provided at the bottom of the inner side of the running channel at the position corresponding to the push strip, a swing block 63 is hingedly installed at one end of the sinking groove 62 close to the bearing seat 8, and blocks 64 that fit the outer side of the seat block 61 are fixedly provided on both sides of the swinging block 63, a straight spring 65 is fixedly connected between the swinging block 63 and the inner wall of the sinking groove 62, an arc-shaped protrusion 611 is fixedly provided on the top of the swinging block 63, wherein, when the swinging block 63 is in the position as shown in the figure, Fig.11 In the state shown, the straight spring 5 65 is still in the stretched state, and the arc-shaped protrusion 611 is just stuck in the slot at the corresponding position, so that after each push, the shell to be packaged can accurately enter the designated position on the gluing station and the residual glue scraping station, and the arc-shaped protrusion 611 can ensure that the push strip can be pushed away from the slot at the current position during the pushing process; The ejecting mechanism 6 also includes a through slot 66 which is opened through one side of the seat block 61 and a limiting frame 610 which is fixed on the outside of the seat block 61. A deflection plate 67 is rotatably installed inside the through slot 66 through a rotating rod. A straight spring 612 is fixedly connected between the end of the deflection plate 67 close to the bearing seat 8 and the mounting plate 2. A ejecting column 69 which is movably sleeved inside the limiting frame 610 is provided on one side of the seat block 61. The top end surface of the ejecting column 69 is an inclined surface, which can ensure that after the finished product is ejected from the supporting slot, it can directly fall into the unloading station along the inclined surface. When the straight spring 612 is in a natural state, the highest point of the ejecting column 69 is exactly flush with the bottom end surface of the loading strip, so that the advancement process of the loading strip will not be hindered. A supporting plate 68 fixedly connected to the outside of the deflection plate 67 is provided at the bottom of the ejecting column 69.

[0034] It should be noted that when the finished product that has been pressed and packaged is pushed out of the supporting slot, after the swinging pendulum 32 passes through the inclined surface on the guiding inclined seat 35 to enter the vertical surface area, as the lifting platform 11 continues to descend, the pendulum 32 will press the deflection plate 67 vertically downward under the limiting action of the straight spring 1 34, and compress the straight spring 612. During this process, the end of the deflection plate 67 close to the guiding inclined seat 35 will deflect downward with the rotating rod as the central axis, so that the other end of the deflection plate 67 drives the supporting plate 68 to deflect upward synchronously, so that the ejector column 69 moves vertically upward under the restriction of the limiting frame 610, allowing the top end of the ejector column 69 to pass through the supporting slot to eject the finished product and slide it to the unloading station.

[0035] Example 2: Refer to the attached specification Figure 1 and Figure 12-13 In one embodiment of the present invention, a transformer coil plastic shell packaging device is provided, wherein a labeling mechanism 7 is arranged between a feeding mechanism 6 and a discharge guide frame 13, and the labeling mechanism 7 comprises a column fixed on the top of a base 1, a bottom plate 72 is fixedly arranged on the top of the column, side frames 71 are fixedly arranged on both sides of the bottom plate 72, a cover plate 73 is fixedly arranged between the top surfaces of the two side frames 71, wherein the cover plate 73 is a U-shaped structure, so that the impeller 75 will not be blocked by the cover plate 73 during the rotation process, brackets 74 are fixedly arranged at both ends of the top of the cover plate 73, an impeller 75 driven by a servo motor is rotatably installed between the two brackets 74, a vacuum suction cup 76 is installed on the outside of the impeller 75, wherein the vacuum suction cup 76 is used to suck the label to be attached, and a stopper assembly 77 is arranged in the middle of the inner side of the two side frames 71.

[0036] It should be noted that in the process of the finished product leaving the material support trough and sliding down the inclined surface of the top of the top column 69, the finished product will fall directly onto the bottom plate 72 and be temporarily blocked by the stop assembly 77 between the opposite sides of the two side frames 71. Then, as the impeller 75 rotates, the vacuum suction cup 76 that sucks the label to be attached will rotate toward the finished product, so that the label can be attached to the side of the finished product. After the labeling is completed, the vacuum suction cup 76 releases the adsorption effect on the label to be attached. Then, as the impeller 75 continues to rotate, it will push the finished product that has been labeled to squeeze the stop assembly 77, so that the finished product that has been labeled can slide directly along the bottom plate 72 to the unloading guide frame 13 for guiding the unloading.

[0037] Specifically, Fig.13As shown, the stopper assembly 77 includes a groove 771 opened on the inner side of the side frame 71, a round rod 772 is fixedly provided inside the groove 771, a baffle 773 is rotatably sleeved on the outer side of the round rod 772, an arc rod 775 is fixedly provided on one side of the baffle 773, an arc tube 776 is fixedly provided on the inner side of the groove 771, and one end of the arc rod 775 is movably inserted into the arc tube 776, an arc spring 777 sleeved on the outer side of the arc rod 775 and the arc tube 776 is fixedly connected between the baffle 773 and the inner wall of the groove 771, and a film pressure sensor 774 is installed on the side of the baffle 773 away from the arc rod 775, wherein the film pressure sensor 774 is used to detect whether the sliding finished product contacts the baffle 773, thereby controlling the rotation of the impeller 75 and controlling the vacuum suction cup 76 to release the adsorption state of the label to be attached.

[0038] It should be noted that when the arc spring 777 is in the natural state, the stopper assembly 77 is just in the Fig.13 In the state shown, at this time, the end of the arc rod 775 away from the baffle 773 is still inserted into the arc tube 776, and the distance between the opposite ends of the two baffles 773 is less than the width of the finished product. In the process of using the stopper assembly 77 to block the finished product that slides onto the bottom plate 72 for labeling, when the sliding finished product contacts the baffle 773, a pressure is applied to the baffle 773 to deform the arc spring 777, but the finished product will not completely break through the baffle 773 and continue to slide. At the same time, the applied force The film pressure sensor 774 will also generate a signal, thereby controlling the servo motor to drive the impeller 75 to rotate 120° through the control end. During this process, the rotating impeller 75 will push the baffle 773 to continue to squeeze the arc spring 777 while pushing the finished product to continue to squeeze the baffle 773. When the film pressure sensor 774 collects a larger pressure signal, it will control the control end to release the adsorption effect of the vacuum suction cup 76 on the label to be attached, so that the finished product with the label can be separated smoothly and continue to slide after completely passing the baffle 773. When the finished product with labeling has completely passed over the baffle 773, the baffle 773 will be reset under the compression restoring force of the arc spring 777 to achieve the action of blocking the labeling of the next round of finished products that slide down.

[0039] In the above technical solution, the electric push rod 10 mentioned is of model HB-DJ801; the servo motor model is JSMA-PUC02D; the vacuum suction cup 76 adopts a miniature vacuum suction cup of model ZP3-T16BS-A12-04; and the film pressure sensor 774 adopts a sheet-type differential pressure sensor of model FSR-A406.

[0040] A method for packaging a transformer coil plastic shell using the above-mentioned transformer coil plastic shell packaging device specifically includes the following steps: S1, material preparation: placing the package shell to be pre-fastened in the material support slot on the material loading strip, adding glue to the liquid capsule, and at the same time, sucking the label to be attached on the material suction side of the vacuum suction cup 76; S2, alternately push and eject the material: the electric push rod 10 is used to push the lifting platform 11 to perform reciprocating lifting and lowering motion, so that the swing bar 32 that performs synchronous lifting and lowering motion is guided by the guide inclined seat 35 to push the push bar to move forward intermittently, thereby driving the packaging shells placed on the material loading bar to flow between the gluing station, the residual glue scraping station and the finished product ejecting station in sequence, and in the process of the swing bar 32 pressing the deflection plate 67 downward, the finished product inside the material holding slot on the material loading bar is ejected by the ejector column 69 lifted by the support plate 68 and slides to the labeling station; S3, labeling: the label is attached to the outside of the packaging shell by the rotating impeller 75, and the finished product is pushed to continue to squeeze the baffle 773, so that the finished product passes the obstacle area and slides onto the unloading guide frame 13 and slides to the receiving station for collection.
