Abstract
Description
Technical Field
[0001] This utility model relates to amorphous magnetic core production equipment, and in particular to an amorphous magnetic core curing and impregnation machine, belonging to the field of electromechanical technology. Background Technology
[0002] In the production of amorphous magnetic cores in strip form, after the core is wound, it needs to be cured. Currently, the curing process used in large-scale production is the impregnation process. This involves preparing a curing solution (usually containing adhesives, also known as curing glue) in advance, placing the wound cores on perforated trays (the trays have upward-facing edges on three or four sides), immersing the trays in the curing solution, removing them, draining the solution, and then proceeding to the next drying step. Currently, this process is done manually, with workers wearing protective gloves moving the cores between workstations. This manual operation has the following problems: First, it is labor-intensive, requiring frequent manual movement between workstations. Preliminary calculations show that the weight moved manually in an 8-hour shift can reach several tons, and the movements are monotonous, leading to fatigue. Second, the curing solution is generally an organic solution containing adhesives, and contains components that are volatile at room temperature, causing air pollution and harm to health. Furthermore, the impregnation process may vary from person to person, potentially leading to differences in quality. Finally, labor costs are high in the long run. Summary of the Invention
[0003] The purpose of this invention is to overcome the above-mentioned problems in the curing of amorphous magnetic cores and to provide an amorphous magnetic core curing and impregnation machine.
[0004] To achieve the purpose of this utility model, the following technical solution is adopted: an amorphous magnetic core curing and impregnation machine, including an impregnation tank and a frame, with a draining tank connected to the rear end of the impregnation tank. The draining tank slopes downward from back to front. A front conveyor belt driven by a first motor is installed above the front part of the impregnation tank, and a rear conveyor belt driven by a second motor is installed above the rear part of the impregnation tank. A first pallet detection switch is installed on the rear side of the front conveyor belt, and a second pallet material detection switch is installed on the front side of the rear conveyor belt. A transfer mechanism is installed above the impregnation tank; the transfer mechanism includes left and right horizontal guide rails located on the gantry frame, left and right sliders are slidably installed on the left and right guide rails, and CNC lead screws in the front and back direction are fixedly connected to the left and right sliders. A mounting plate is fixedly connected to the nut of the CNC lead screw, and three drive cylinders that move in the up and down direction are fixedly installed on the mounting plate at the front and back respectively. The actuating end of the drive cylinder is fixedly connected to a gripper cylinder; the width between two adjacent gripper cylinders is adapted to the distance between the edges on both sides of the magnetic core tray; An impregnation drive mechanism is installed on the impregnation tank. The impregnation drive mechanism includes two impregnation cylinders that are fixedly installed on the outer sides of the impregnation tank in the vertical direction. A connecting frame is fixedly connected to the cylinder rod of each impregnation cylinder. The connecting frame is fixedly connected to the support frame. The support frame is located above the impregnation tank. The cylinder drives the support frame to move up and down in and out of the impregnation tank. The aforementioned motor, cylinder, and detection switch are all connected to the controller for control.
[0005] Furthermore, a front inclined groove is connected to the front end of the impregnation tank, and the front inclined groove slopes downward from front to back.
[0006] Furthermore, each side of the connecting bracket is equipped with two vertical sliders that are fixedly connected in the vertical direction. The two vertical sliders slide and engage with two vertical guide rails, which are located at the front and rear of the impregnation cylinder, respectively.

[0013] To more fully explain the implementation of this utility model, implementation examples are provided. These implementation examples are merely illustrative of this utility model and do not limit its scope.
[0014] The present invention will be further explained in detail with reference to the accompanying drawings, in which the following references are made: 1: frame; 2: front conveyor belt; 3: rear conveyor belt; 4: impregnation tank; 5: front inclined trough; 6: drain tank; 7: left and right guide rails; 8: left and right sliders; 9: CNC lead screw; 10: mounting plate; 11: first drive cylinder; 12: first gripper cylinder; 13: support frame; 14: second drive cylinder; 15: second gripper cylinder; 16: third drive cylinder; 17: third gripper cylinder; 18: tray; 19: impregnation cylinder; 20: connecting frame; 21: upper and lower guide rails; 22: upper and lower sliders.
[0015] As shown in the attached figure, an amorphous magnetic core curing and impregnation machine includes an impregnation tank 4 and a frame. A drain tank 6 is connected to the rear end of the impregnation tank, and the drain tank slopes downward from back to front. A front inclined trough 5 is also connected to the front end of the impregnation tank. The front inclined trough 5 can catch the curing liquid adhering to the third gripper cylinder and the second gripper cylinder. The front inclined trough slopes downward from front to back. A front conveyor belt 2 driven by a first motor is installed above the front part of the impregnation tank, and a rear conveyor belt 3 driven by a second motor is installed above the rear part of the impregnation tank. A dryer can be directly connected after the rear conveyor belt of this equipment. The tray flows out of the rear conveyor belt and directly enters the dryer.
[0016] A first pallet detection switch is installed on the rear side of the front conveyor belt, and a second pallet material detection switch is installed on the front side of the rear conveyor belt. The first motor can be a conventional motor; when the first pallet detection switch detects a pallet, it stops the first motor. The second motor can be a servo motor or a stepper motor; when the second pallet detection switch detects a pallet, the second motor drives the conveyor belt to move backward a certain distance. The pallet detection switches can be photoelectric switches, proximity switches, or lights. The front and rear conveyor belts and their control methods are commonly used existing technologies in material conveying.
[0017] A transfer mechanism is installed above the impregnation tank. The transfer mechanism includes left and right horizontal guide rails 7 located on the gantry frame. Left and right sliders 8 are slidably installed on the left and right guide rails 7. CNC lead screws 9 in the front and back direction are fixedly connected to the left and right sliders. A mounting plate 10 is fixedly connected to the nut of the CNC lead screw 9. Three drive cylinders that move in the up and down direction are fixedly installed on the mounting plate. The actuating end of the drive cylinder is fixedly connected to a gripper cylinder. The width between two adjacent gripper cylinders is adapted to the distance between the edges on both sides of the magnetic core tray. In the figure, the three drive cylinders are the first drive cylinder 11, the second drive cylinder 14, and the third drive cylinder 16. The first gripper cylinder 12, the second gripper cylinder 15, and the third gripper cylinder 17 are fixedly connected to the corresponding drive cylinders. The first and second drive cylinders are responsible for transferring the tray from the support frame to the rear conveyor belt, and the second and third drive cylinders are responsible for transferring the tray from the front conveyor belt to the support plate. The use of three drive cylinders avoids the use of CNC lead screws with too long a stroke.
[0018] A glue-dipping drive mechanism is installed on the glue-dipping tank. The glue-dipping drive mechanism includes two vertically oriented glue-dipping cylinders 19 fixedly installed on both sides of the glue-dipping tank. Each cylinder rod is fixedly connected to a connecting frame 0, which is fixedly connected to a support frame 13 located above the glue-dipping tank. The cylinders drive the support frame to move up and down in and out of the glue-dipping tank. In this embodiment, each connecting frame is equipped with two vertically oriented sliders 22, which are slidably engaged with two vertically oriented guide rails 21 located at the front and rear of the glue-dipping cylinders, respectively. The aforementioned motor, cylinders, and detection switches are all connected to a controller.
[0019] To enable the front conveyor belt to start automatically after the pallet is loaded, a third pallet detection switch can be installed in front of the front conveyor belt. The third pallet detection switch is connected to the controller. After the third pallet detection switch detects the pallet, it controls the first motor.
[0020] The working process of this dipping machine is as follows: The left and right sliders are adjusted to the appropriate positions, and the pallet is placed on the front conveyor belt. The first motor starts. After the first pallet detection switch detects the pallet, the first motor stops. The CNC screw starts, moving the second and third drive cylinders above the corresponding edge of the pallet. The second and third drive cylinders drive the gripper cylinders downwards, causing the edge to enter the gripper. The gripper cylinders clamp the edge. The second and third drive cylinders move upwards. The CNC screw moves the pallet above the support frame. The second and third drive cylinders move downwards. After the pallet falls onto the support frame, the second and third gripper cylinders release, and the second and third drive cylinders... The process involves an upward reset, where the CNC screw drives the first and second drive cylinders to move above the corresponding edge of the tray. The dipping cylinder then moves downwards to immerse the tray in the curing liquid. The dipping cylinder then moves upwards to lift the tray. The first and second drive cylinders then drive the gripper cylinder downwards to bring the edge into the gripper. The gripper cylinder then clamps the edge. The first and second drive cylinders move upwards. The CNC screw moves the tray above the rear conveyor belt. The first and second drive cylinders then move downwards. The tray falls onto the rear conveyor belt, and the gripper cylinder releases. The second tray detection switch detects the tray and the conveyor belt moves backward a certain distance. The tray drains on the rear conveyor belt, and the drained liquid falls into the drain tank and then flows into the dipping tank.
