Description

Technical Field

[0001] The invention relates to an inductor manufacturing device, in particular to an inductor forming machine. Background Art

[0002] Inductors are also called inductors. During production, after the coil is wound on the frame, it needs to be potted and molded. The current potting method is generally mold potting, which places the inductor in the mold, then injects the potting material, and demolds it after solidification. When the inductor to be produced is small in size, during the potting molding process, the solidified inductor is difficult to remove from the mold, or the solidified potting material is difficult to completely remove from the mold, which affects the molding quality of the inductor and makes it difficult to improve the production efficiency of the inductor. Therefore, there is an urgent need for a device that can improve the production quality of inductors, especially for smaller inductors. Summary of the invention

[0003] The purpose of the present invention is to provide an inductor forming machine to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.

[0004] The solution of the present invention to solve its technical problem is:

[0005] The inductor forming machine comprises: a forming mechanism, comprising a lower die, an upper die located above the lower die, the upper die can be moved downward to approach the lower die or upward to move away from the lower die, a limiting groove is arranged on the top side of the lower die, a plurality of lower negative pressure holes are arranged on the top side of the lower die and the inner wall of the limiting groove respectively, a lower heating source is arranged in the lower die, a plurality of upper negative pressure holes are arranged on the bottom side of the upper die opposite to the limiting groove, and an upper heating source is arranged in the upper die; a belt pulling mechanism, comprising a unwinding device and a winding device located on both sides of the lower die; a feeding mechanism, having a feeding end which can be close to or away from the limiting groove; a transferring mechanism, having a transferring end which can be close to or away from the bottom side of the upper die.

[0006] The technical scheme has at least the following beneficial effects: in the belt pulling mechanism, the unwinding device is loaded with a material belt, and after the material belt is pulled out, it passes through the top side of the lower mold and is loaded into the reeling device, and the reeling device reels the material belt, and the material belt is used to separate the potting material and the lower mold from each other, such as release paper. During the production of inductor molding, the lower negative pressure hole on the top side of the lower mold generates negative pressure, which sucks the material belt downward to abut against the top side of the lower mold, and makes the material belt sink at the position of the limiting groove to form a lower mold cavity, and the transfer end in the transfer mechanism transfers the material plate loaded with the workpiece to be potted into the bottom side of the upper mold, and the material plate is adsorbed and fixed by multiple upper negative pressure holes on the bottom side of the upper mold, and then the transfer end leaves the bottom side of the upper mold, and the feeding end in the feeding mechanism moves toward the limiting groove, and the potting material is fed into the lower mold cavity formed by the sinking of the material belt. In the initial state, the potting material is in a solid state, and the potting material is heated to a molten state by the lower heating source in the lower mold. The upper mold is moved down to the lower mold for mold closing. The upper heating source in the upper mold also heats the potting material to ensure that the potting material is heated more evenly, so that the molten potting material can be better filled into the empty space formed by the mold closing. After molding, the negative pressure suction of the lower negative pressure hole on the material strip is cancelled. When the upper mold is moved up and away from the lower mold, the material plate loaded with the potting and molding workpiece can be easily moved out of the limiting groove. Then the transfer end of the transfer mechanism is close to the bottom side of the upper mold to move the material plate loaded with the potting and molding workpiece out. At this time, the unwinding device releases a new material strip, and the winding device winds it up, so that the material strip used in the last molding is moved out of the lower mold. In this way, the material strip is adsorbed by negative pressure on the top side of the lower mold to form a lower mold cavity in the limiting groove. The material strip can be updated each time the inductor is potted and molded, so as to achieve rapid demolding, and effectively solve the problem of potting material residue in the limiting groove, thereby improving the overall production efficiency and quality.

[0007] As a further improvement of the above technical solution, the unwinding device includes an unwinding frame, an unwinding motor, an unwinding lifting drive, an unwinding slider and an unwinding guide roller, the unwinding frame is located on one side of the lower mold, the unwinding motor and the unwinding lifting drive are respectively connected to the unwinding frame, the unwinding motor drive is connected to the unwinding roller, the unwinding lifting drive is transmission-connected to the unwinding slider, the unwinding guide roller is rotatably connected to the unwinding slider, the unwinding lifting drive can drive the unwinding slider to move downward and make the material strip passing through the unwinding guide roller close to the lower mold, or the unwinding lifting drive can drive the unwinding slider to move upward and make the material strip passing through the unwinding guide roller away from the lower mold. The cylindrical material strip is loaded onto the unwinding roller, and the material strip is pulled out and bypassed by the unwinding guide roller. The material strip is guided by the unwinding guide roller and then led out. After passing over the top of the lower die, it is sent to the winding device. When the inductor molding production is required, the unwinding lifting drive drives the unwinding slider to move downward, and the unwinding guide roller on the unwinding slider moves downward, driving the material strip downward on one side to press against the top side of the lower die. At this time, the lower negative pressure hole on the lower die performs vacuum adsorption on the material strip again, which can better make the material strip sink in the limiting groove to form a lower die cavity. When the material strip needs to be updated, the unwinding lifting drive drives the unwinding slider to move upward, and the unwinding guide roller on the unwinding slider also moves upward, so that the material strip moves upward away from the lower die. At this time, the material strip and the lower die are in a non-contact state, and no friction will be generated with the lower die when the material strip is wound, thereby improving the smoothness of the material strip update.

[0008] As a further improvement of the above technical solution, the winding device includes a winding frame, a winding motor, a winding lifting drive, a winding slider and a winding guide roller. The winding frame is located on the other side of the lower mold, and the winding motor and the winding lifting drive are respectively connected to the winding frame, the winding motor drive is connected to the winding roller, the winding lifting drive is transmission-connected to the winding slider, and the winding guide roller is rotatably connected to the winding slider, the winding lifting drive can drive the winding slider to move downward and make the material strip passing through the winding guide roller close to the lower mold, or the winding lifting drive can drive the winding slider to move upward and make the material strip passing through the winding guide roller away from the lower mold. The material strip that is led out from the unwinding device and passes over the top of the lower mold bypasses the winding guide roller, is guided by the winding guide roller, and then led out and wound on the winding roller. When the inductor molding production is required, the winding lifting drive drives the winding slider to move downward, and the winding guide roller on the winding slider moves downward, driving the material strip downward on the other side to press against the top side of the lower mold. At this time, the lower negative pressure hole on the lower mold performs vacuum adsorption on the material strip, which can further improve the sinking molding effect of the material strip in the limiting groove. When the material strip needs to be updated, the winding lifting drive drives the winding slider to move upward, and the winding guide roller on the winding slider also moves upward, so that the material strip moves upward away from the lower mold. At this time, the material strip and the lower mold are in a non-contact state, and no friction will be generated with the lower mold when the material strip is wound, thereby improving the smoothness of the material strip update.

At this time, the rotating conveyor belt stops working, and the transfer end can move to the rotating conveyor belt to take out the material plate and transfer it to the bottom side of the upper mold for loading. When the material plate after the inductor molding production is completed is taken out from the bottom side of the upper mold, it can also be moved to the rotating conveyor belt by the transfer end, and the rotating conveyor belt transfers the material plate to the next station. This can facilitate loading and unloading, improve the overall automation level, and further improve the overall production efficiency.

[0010] As a further improvement of the above technical solution, the conveying mechanism also includes a material blocking drive, a material blocking block, a material supporting drive and a material supporting frame. The material supporting drive and the material blocking drive are sequentially connected to the top side of the conveying frame along the conveying direction of the rotary conveyor belt.

The material supporting drive can drive the material supporting frame to protrude upward from the rotary conveyor belt or to be retracted downward into the rotary conveyor belt. The transferring end can move between the material supporting frame and the bottom side of the upper mold. When the material sheet is transferred to the side of the lower mold on the rotary conveyor belt, the material blocking drive drives the material blocking block to protrude upward from the gap between the two rotary conveyor belts to block the material sheet, which can better limit the transfer position of the material sheet and prevent the material sheet from inertial sliding on the rotary conveyor belt. Then the material supporting drive drives the supporting rack to protrude upward from the rotary conveyor belt and lift the material sheet from the rotary conveyor belt. This can ensure the accuracy of the material sheet's moving stroke. At this time, the transfer end moves close to the supporting rack to take out the material sheet and transfer it to the bottom side of the upper mold.

[0012] As a further improvement of the above technical solution, the transfer mechanism includes a transfer lifting drive, a transfer lifting seat, a transfer translation drive, a transfer translation seat, a transfer rotation drive, a transfer frame and a transfer suction cup.

The transfer suction cup is connected to the transfer frame, and the transfer suction cup is the transfer end. The transfer lifting drive and the transfer translation drive can provide driving force for the transfer suction cup to reciprocate in the up and down directions and in the horizontal direction respectively. When the material sheet needs to be loaded to the bottom side of the upper mold, the transfer lifting drive drives the transfer suction cup to move downward. After the transfer suction cup adsorbs the material sheet, the transfer lifting drive moves upward, and the transfer translation drive drives the transfer suction cup to move horizontally to the bottom of the upper mold. At this time, the transfer rotation drive drives the transfer frame to rotate upward to transfer the material sheet to the top, and the transfer lifting drive drives the material sheet to move up again to realize the loading of the material sheet. After completion, the transfer lifting drive moves downward, and the transfer translation drive drives the transfer suction cup away from the upper mold, and the transfer rotation drive drives the transfer frame to rotate downward to prepare for the next loading of the material sheet.

[0014] As a further improvement of the above technical solution, the feeding mechanism includes a weighing device, the weighing device has a weighing outlet, and the feeding end can move between the weighing outlet and the limiting groove. The potting material to be fed is loaded into the weighing device, and each time the inductor is formed, the required weight of the potting material is removed by the weighing device and dropped into the transfer end from the weighing outlet, and then the transferor transfers the potting material to the limiting groove, so that the production quality and cost can be better controlled by weighing the material, and the production efficiency can be improved.

[0015] As a further improvement of the above technical solution, the feeding mechanism also includes a feeding translation drive, a feeding translation seat, a loading plate, a sealing drive and a sealing plate. The feeding translation drive is transmission connected to the feeding translation seat, and the feeding translation drive can drive the feeding translation seat to move between the limiting groove and the weighing outlet.

At this time, the material is discharged from the weighing outlet to the sealing plate, and the sealing plate supports the potting material. Then the feeding translation drive drives the loading plate to move to the top of the lower mold, and then the sealing drive drives the sealing plate to open the loading port. At this time, the potting material falls into the lower mold cavity formed by the material belt from the loading port because there is no sealing plate to support it, thereby realizing the feeding of the potting material. After completion, the feeding translation drive drives the loading plate away from the lower mold, and the sealing drive drives the sealing plate to cover the loading port again to prepare for the next feeding.

[0026] Reference Figure 1 The inductor forming machine includes a forming mechanism, a drawing mechanism, a feeding mechanism 300 and a transfer mechanism 400, wherein the forming mechanism includes a lower die 110 and an upper die, the upper die is installed above the lower die 110, the upper die can move downward to approach the lower die 110 or move upward away from the lower die 110, a limiting groove 111 is arranged on the top side of the lower die 110, a plurality of lower negative pressure holes are arranged on the top side of the lower die 110 and the inner wall of the limiting groove 111, a lower heating source is arranged in the lower die 110, a plurality of upper negative pressure holes are arranged on the bottom side of the upper die facing the limiting groove 111, and the upper An upper heating source is arranged in the mold, and the upper heating source and the lower heating source are heatable structural parts, for example, electric heating plates, heating tubes, etc. Naturally, the molding mechanism includes an upper negative pressure generator and a lower negative pressure generator, and the upper negative pressure generator generates a negative pressure adsorption force on multiple upper negative pressure holes, and the lower negative pressure generator generates a negative pressure adsorption force on multiple lower negative pressure holes; the pulling mechanism includes a unwinding device 210 and a winding device 220 located on both sides of the lower mold 110; the feeding mechanism 300 has a feeding end that can be close to or away from the limiting groove 111; the transferring mechanism 400 has a transferring end that can be close to or away from the bottom side of the upper mold.

[0027] As can be seen from the above, in the belt pulling mechanism, the unwinding device 210 is loaded with a material belt, and after the material belt is pulled out, it passes through the top side of the lower mold 110 and is loaded into the reeling device 220, and the reeling device 220 reels the material belt, and the material belt is used to separate the potting material and the lower mold 110 from each other, such as release paper. During the inductor molding production, the lower negative pressure hole on the top side of the lower mold 110 generates negative pressure, which sucks the material belt downward to the top side of the lower mold 110, and makes the material belt sink at the position of the limiting groove 111 to form The transfer end in the transfer mechanism 400 transfers the material plate loaded with the workpiece to be potted into the bottom side of the upper mold, and the material plate is adsorbed and fixed by the multiple upper negative pressure holes on the bottom side of the upper mold. Then the transfer end leaves the bottom side of the upper mold, and the feeding end in the feeding mechanism 300 moves toward the limiting groove 111, and the potting material is fed into the lower mold cavity formed by the sinking of the material belt. In the initial state, the potting material is in a solid state. The lower heating source in the lower mold 110 is used to heat the potting material to a molten state, and the upper mold is The upper mold moves downward to approach the lower mold 110 for mold closing. The upper heating source in the upper mold also heats the potting material to ensure that the potting material is heated more evenly, so that the molten potting material can be better filled into the empty space formed by the mold closing. After molding, the negative pressure suction of the lower negative pressure hole on the material strip is cancelled. When the upper mold moves upward away from the lower mold 110, the material plate loaded with the potting molding workpiece can be easily moved out of the limiting groove 111. Then the transfer end of the transfer mechanism 400 is close to the bottom side of the upper mold to move the material plate loaded with the potting molding workpiece out. At this time, the unwinding device 210 releases a new material strip, and the winding device 220 winds it up, so that the material strip used in the last molding is moved out of the lower mold 110. In this way, the material strip is adsorbed by negative pressure on the top side of the lower mold 110 to form a lower mold cavity in the limiting groove 111. The material strip can be updated each time the inductor is potted and molded, so as to achieve rapid demolding, and effectively solve the problem of potting material residue in the limiting groove 111, thereby improving the overall production efficiency and quality.

[0028] The unwinding device 210 is mainly used to unwind the material strip. Since the lower mold 110 needs to perform negative pressure adsorption on the material strip, the distance between the material strip and the lower mold 110 cannot be too large. However, when the material strip is replaced, it needs to move relative to the lower mold 110. In order to reduce the wear on the material strip and improve the smoothness of the movement of the material strip, in this embodiment, Figure 3As shown, the unwinding device 210 includes an unwinding frame 211, an unwinding motor 212, an unwinding lifting drive 213, an unwinding slider 214 and an unwinding guide roller 215. The unwinding frame 211 is located on one side of the lower mold 110, the unwinding motor 212 and the unwinding lifting drive 213 are respectively connected to the unwinding frame 211, the unwinding motor 212 is drivingly connected to the unwinding roller, the unwinding lifting drive 213 is transmission-connected to the unwinding slider 214, the unwinding guide roller 215 is rotatably connected to the unwinding slider 214, the unwinding lifting drive 213 can drive the unwinding slider 214 to move downward and make the material strip passing through the unwinding guide roller 215 close to the lower mold 110, or the unwinding lifting drive 213 can drive the unwinding slider 214 to move upward and make the material strip passing through the unwinding guide roller 215 away from the lower mold 110. The cylindrical material strip is loaded onto the unwinding roller, and after being pulled out, the material strip passes around the unwinding guide roller 215, and is guided by the unwinding guide roller 215 and then led out, and is sent to the winding device 220 after passing over the top of the lower mold 110. When the inductor molding production is required, the unwinding lifting drive 213 drives the unwinding slider 214 to move downward, and the unwinding guide roller 215 on the unwinding slider 214 moves downward, driving the material strip downward on one side to abut against the top side of the lower mold 110. At this time, the lower negative pressure on the lower mold 110 The pressing hole then vacuum absorbs the material strip, which can better sink the material strip in the limiting groove 111 to form a lower mold cavity. When the material strip needs to be updated, the unwinding lifting drive 213 drives the unwinding slider 214 to move upward, and the unwinding guide roller 215 on the unwinding slider 214 also moves upward, so that the material strip moves upward away from the lower mold 110. At this time, the material strip and the lower mold 110 are in a non-contact state, and no friction will be generated with the lower mold 110 when the material strip is rolled up, thereby improving the smoothness of updating the material strip. Of course, the unwinding slider 214 is connected to the unwinding frame 211 in a sliding manner in the up and down direction, which can improve the stability and smoothness of the up and down movement of the unwinding slider 214. In addition, a tensioning roller is also provided on the unwinding roller. The material strip pulled from the unwinding roller passes through the tensioning roller and then bypasses the unwinding guide roller 215. The tensioning roller is used to increase the tension of the material strip when unwinding.

[0029] Similarly, the winding device 220 includes a winding frame 221, a winding motor 222, a winding lifting drive 223, a winding slider 224 and a winding guide roller 225. The winding frame 221 is located on the other side of the lower mold 110, the winding motor 222 and the winding lifting drive 223 are respectively connected to the winding frame 221, the winding motor 222 is drivingly connected to the winding roller, the winding lifting drive 223 is transmission-connected to the winding slider 224, and the winding guide roller 225 is rotatably connected to the winding slider 224. The winding lifting drive 223 can drive the winding slider 224 to move downward and make the material strip passing through the winding guide roller 225 approach the lower mold 110, or the winding lifting drive 223 can drive the winding slider 224 to move upward and make the material strip passing through the winding guide roller 225 away from the lower mold 110. The material strip led out from the unwinding device 210 and passing over the top of the lower mold 110 passes around the winding guide roller 225, and is guided by the winding guide roller 225 and then led out and wound on the winding roller. When it is necessary to produce the inductor molding, the winding lifting drive 223 drives the winding slider 224 to move downward, and the winding guide roller 225 on the winding slider 224 moves downward, driving the material strip downward to press against the top side of the lower mold 110 on the other side. At this time, the lower negative pressure hole on the lower mold 110 performs vacuum adsorption on the material strip, which can further improve the sinking molding effect of the material strip in the limiting groove 111. When the material strip needs to be updated, the winding lifting drive 223 drives the winding slider 224 to move upward, and the winding guide roller 225 on the winding slider 224 also moves upward, so that the material strip moves upward away from the lower mold 110. At this time, the material strip and the lower mold 110 are in a non-contact state, and no friction is generated with the lower mold 110 when the material strip is rolled up, thereby improving the smoothness of updating the material strip. Similarly, the winding slider 224 is connected to the winding frame 221 by sliding in the up and down directions, which can improve the stability and smoothness of the up and down movement of the winding slider 224. In addition, a tensioning roller is also provided on the winding roller. The material strip pulled from the winding roller passes through the tensioning roller and then bypasses the winding guide roller 225. The tensioning roller is used to increase the tensioning force of the material strip when winding.

[0030] In the above embodiment, the material sheet loaded with the workpiece to be potted can be placed manually at a set position, and the transfer end is repeatedly moved to the position to load the material sheet, and in order to further improve the overall production efficiency, such as Figure 2As shown, the present invention also includes a conveying mechanism 500, which includes a conveying frame 510 and a belt conveyor 520. The conveying frame 510 is located beside the lower mold 110, and the belt conveyor 520 is arranged on the conveying frame 510. The belt conveyor 520 is formed with at least two rotary conveyor belts arranged at intervals, and the transfer end can move between the rotary conveyor belt and the bottom side of the upper mold. The material sheet with the workpiece to be potted is placed on the belt conveyor 520, and the rotary conveyor belt rotating in the belt conveyor 520 moves the material sheet to the side of the lower mold 110. At this time, the rotary conveyor belt stops working, and the transfer end can move to the rotary conveyor belt to take out the material sheet and transfer it to the bottom side of the upper mold for loading. After the material sheet after the inductor molding production is completed is taken out from the bottom side of the upper mold, it can also be moved to the rotary conveyor belt by the transfer end, and the rotary conveyor belt transfers the material sheet to the next workstation. This can facilitate loading and unloading, improve the overall automation level, and further improve the overall production efficiency.

[0031] After the rotary conveyor belt has transported the material sheet to the right position, the material sheet can be stopped at the set position only by stopping the rotary conveyor belt. When the rotary conveyor belt transports the material sheet too fast, the material sheet is prone to relative slippage on the rotary conveyor belt after the rotary conveyor belt stops moving. Therefore, in order to further improve the accuracy of the material sheet being transferred to the right position, in this embodiment, the conveying mechanism 500 also includes a material blocking drive 530, a material blocking block 540, a material supporting drive 550 and a material supporting frame 560. The material supporting drive 550 and the material blocking drive 530 are sequentially connected to the top side of the conveying frame 510 along the conveying direction of the rotary conveyor belt. The material blocking drive 530 is transmission-connected to the material blocking block 540, and the material blocking drive 530 can drive the material blocking block 540 to protrude upward from the gap between the two rotary conveyor belts or to be retracted downward into the rotary conveyor belt. The material supporting drive 550 can drive the supporting frame 560 to protrude upward from the rotary conveyor belt or to be retracted downward into the rotary conveyor belt. The transfer end can move between the supporting frame 560 and the bottom side of the upper mold. Naturally, an avoidance space is provided on the top side of the conveying frame 510 corresponding to the position of the material blocking plate and the supporting frame 560, so that the material blocking plate and the supporting frame 560 can extend upward from the supporting frame 560 and protrude from the rotary conveyor belt. When the material sheet is transferred to the side of the lower mold 110 on the rotary conveyor belt, the material blocking drive 530 drives the material blocking block 540 to protrude upward from the gap between the two rotary conveyor belts to block the material sheet, which can better limit the transfer position of the material sheet and prevent the material sheet from inertial sliding on the rotary conveyor belt. Then the material supporting drive 550 drives the supporting rack 560 to protrude upward from the rotary conveyor belt and lift the material sheet from the rotary conveyor belt. In this way, the accuracy of the material sheet's moving stroke can be ensured. At this time, the transfer end moves again to be close to the supporting rack 560, takes out the material sheet and transfers it to the bottom side of the upper mold.

The transfer lifting drive 410 and the transfer translation drive 430 can respectively provide driving force for the transfer suction cup 470 to reciprocate in the up and down directions and in the horizontal direction. When the material sheet needs to be loaded to the bottom side of the upper mold, the transfer lifting drive 410 drives the transfer suction cup 470 to move downward. After the transfer suction cup 470 adsorbs the material sheet, the transfer lifting drive 410 moves upward, and the transfer translation drive 430 drives the transfer suction cup 470 to move horizontally to the bottom of the upper mold. At this time, the transfer rotation drive 450 drives the transfer frame 460 to rotate upward to transfer the material sheet to the top, and the transfer lifting drive 410 drives the material sheet to move up again to realize the loading of the material sheet. After completion, the transfer lifting drive 410 moves downward, and the transfer translation drive 430 drives the transfer suction cup 470 away from the upper mold, and the transfer rotation drive 450 drives the transfer frame 460 to rotate downward to prepare for the next loading of the material sheet.

When the material plate needs to be placed in the cooling box 600, the cooling translation drive drives the cooling box 600 to move above the support rack 560. At this time, the transfer suction cup 470 can directly place the material plate into the cooling box 600 through translation and up and down movement, saving the active driving source at the transfer end and improving the convenience of the transfer end in transferring the material plate between the support rack 560, the bottom side of the upper mold, and the cooling box 600.

[0037] The feeding end in the feeding mechanism 300 can be used only for transferring the potting material. At this time, the potting material can be manually loaded on the feeding end, and then moved from the feeding end to the top of the lower mold 110 for loading, or the potting material can be loaded into the feeding end each time by an external device. In order to improve the overall automation level, Figure 4 As shown, in this embodiment, the feeding mechanism 300 includes a weighing device, the weighing device has a weighing outlet, and the feeding end can move between the weighing outlet and the limiting groove 111.

The transfer box 362 is connected to each other, the storage barrel 364 and the discharge barrel 363 are staggered in the up-down direction, the stirring paddle is connected to the storage barrel 364 along the axis of the up-down direction, the material-pickup gear is connected to the transfer box 362 along the axis of the up-down direction, and a plurality of material-pickup grooves are arranged around the outer periphery of the material-pickup gear, and the rotation path of the outer periphery of the material-pickup gear passes directly below the storage barrel 364 and directly above the discharge barrel 363.

At this time, the weighing instrument 361 keeps weighing the transfer box 362 and the storage barrel 364, so as to know the weight of the material fed into the discharge barrel 363 and discharged outward.

At this time, the material is discharged from the weighing outlet to the sealing plate 350, and the sealing plate 350 supports the potting material. Then the feeding translation drive 310 drives the loading plate 330 to move to the top of the lower mold 110, and then the sealing drive 340 drives the sealing plate 350 to open the loading port. At this time, the potting material falls into the lower mold cavity formed by the material belt from the loading port because there is no sealing plate 350 to support it, so as to realize the feeding of the potting material. After completion, the feeding translation drive 310 drives the loading plate 330 away from the lower mold 110, and the sealing drive 340 drives the sealing plate 350 to cover the loading port again to prepare for the next feeding.
