Description

[Technical field]

[0001] The invention belongs to the technical field of winding rubber coating, and in particular relates to a winding opening and closing clamp for hollow coils of household appliance reactors and microwave oven transformers. [Background technology]

[0002] The coil is an important part of the reactor and transformer in small household appliances. Since the coil is wound in layers to form turns, with the development of mechanization today, many automatic winding machines have appeared. Each process on the machine affects the production efficiency of the product. While strictly controlling the product quality, controlling costs and improving production efficiency are sufficient conditions for obtaining greater profits. Usually, the machine wraps the wire on the fixture and then wraps it with glue. After the wrapping is completed, the coil needs to be removed and recycled for the process. The current winding fixture has a complex structure, resulting in more assembly processes for the fixture, resulting in higher production costs and inconvenience in use. Therefore, the coil is slow to remove, and mass production requires a longer cycle, which consumes a large amount of time and slows down the overall work efficiency of the machine. [Summary of the invention]

[0003] In order to solve the existing problems in the background technology, the present invention provides a winding opening and closing fixture for hollow coils of household appliance reactors and microwave oven transformers, which has a simple structure, simple and fast control process, and the rapid removal of the coil facilitates the rapid circulation process and improves production efficiency.

[0004] The present invention adopts the following technical solutions:

[0005] The invention discloses a winding opening and closing fixture for hollow coils of household appliance reactors and microwave oven transformers, comprising a fixture base, a fixture bottom block, side plates, a latch, a pressure block, an upper cover plate and a lower cover plate. The upper cover plate and the lower cover plate can be disassembled and assembled, and form a winding station for winding coils between each other. The lower cover plate is fixed on the fixture base block, the fixture base block is fixed on the fixture base, the side plates are installed and embedded in the middle of the two sides of the fixture base block, the pressure block is slidably arranged on the side plates, the bottom of the latch is elastically connected to the fixture base, the latch slides from bottom to top through the fixture base block, and the outward side of the latch slides with the inside of the pressure block, so that the pressure block slides toward or away from each other synchronously, the pressure block is separated from the upper cover plate when it moves away from each other, and the pressure block is locked to the upper cover plate when it moves toward each other.

[0006] Furthermore, one end of the latch is a pin head, and the other end is provided with a plug hole. The pin head has a bevel end. The pin head passes through the pressing block and slides by slidingly fitting with the bevel end.

[0007] Furthermore, a spring is sleeved on one end of the plug hole and elastically connected to the clamp base.

[0008] Furthermore, a slide groove matched with the pressure block is provided on the side plate, and the pressure block is slidably placed in the slide groove. A pin shaft is provided in the pressure block, and one end of the pin head on the latch passes through the top of the pressure block. When the latch moves downward, the inclined surface end gradually slides with the pin shaft to make the pressure block slide outward. After the latch is pushed up, the inclined surface end gradually separates from the pin shaft, and the pressure block slides inward.

[0009] Furthermore, it also includes two embedded blocks, which are clamped in the clamp bottom block and the lower cover plate, and the coils are wound on the outside of the embedded blocks in sequence.

[0010] Furthermore, the upper cover plate has a locking block, which is provided with a slot corresponding to the inner end of the pressure block. The locking block is placed between the two embedded blocks. When the pressure block moves outward, it disengages from the slot, and when the pressure block moves inward, it correspondingly engages in the slot.

[0011] Furthermore, it also includes a mounting plate and a motor, the fixture base and the motor are respectively mounted on both sides of the mounting plate, and the motor and the fixture base are drivingly connected.

[0012] Furthermore, a sensor is arranged on the mounting plate next to the fixture base, the sensor and the motor are connected to an external controller, a positioning plate is installed on the fixture base, and the sensor is used to identify the position of the positioning plate.

[0013] The beneficial effects of the present invention are as follows:

[0014] The opening and closing clamp has a simple overall structure, is easy to assemble, has a low manufacturing cost, and saves investment costs.

[0015] The structure is compact and ingenious. The upper cover can be disassembled and locked by controlling the latch to slide up and down. Therefore, the coil can be quickly taken out after the rubber coating is completed, and the upper cover can be quickly assembled and locked to repeat the process cycle, shortening the connection time between processes and improving production efficiency. After the latch is pulled down, the inclined end of the pin head and the pin shaft produce a sliding fit, and the pressure block slides outward under pressure to disengage from the slot. The upper cover is quickly disassembled and the coil is taken out. After the upper cover is installed again, the latch is lifted and slides upward, and the pressure block slides inward and is inserted into the slot to quickly lock the upper cover and repeat the process. The use and control are convenient and fast, which greatly improves production efficiency.

[0021] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not limited to the present invention.

[0022] Figure 1 The invention discloses a wire winding opening and closing fixture for the hollow coil 1 of a household appliance reactor and a microwave oven transformer, which can be quickly opened and locked after winding and encapsulation, thereby shortening the time for removing the coil 1 and the connection time of the preparation process before winding, thereby shortening the time of the entire process and improving efficiency.

[0023] Specifically, Figure 2 As shown, the opening and closing fixture includes a fixture base 2, a fixture bottom block 3, a side plate 4, a latch 5, a pressure block 6, an upper cover plate 7, a lower cover plate 8 and two inserts 9, the upper cover plate 7 and the lower cover plate 8 can be disassembled and assembled, the two inserts 9 are fixedly clamped in the lower cover plate 8, and the upper cover plate 7 and the lower cover plate 8 form a winding station for winding the coil 1, the lower cover plate 8 is fixed on the fixture bottom block 3, the fixture bottom block 3 is fixed on the fixture base 2, the side plate 4 is installed and embedded in the middle of the two sides of the fixture bottom block 3, and a slide groove 41 adapted to the pressure block 6 is provided on the side plate 4. The pressing block 6 is slidably placed in the sliding groove 41, and the bottom of the latch 5 is elastically connected to the fixture base 2. Therefore, the latch 5 can slide from bottom to top through the fixture bottom block 3 and the outward side of the latch 5 slides with the inside of the pressing block 6 to make the pressing block 6 slide towards or away from each other synchronously. When the pressing block 6 moves away from each other, it disengages from the upper cover plate 7, and when the pressing block 6 moves towards each other, it locks the upper cover plate 7. Obviously, by controlling the up and down movement of the latch 5, the upper cover plate 7 can be quickly disengaged and locked, the action connection time is extremely short, the operation cycle is shortened, and the efficiency is improved.

[0024] The above scheme has a specific implementation structure as follows: Figure 3 and Figure 4 As shown, the upper cover plate 7 has a locking block 71, and a slot 710 corresponding to the inner end of the pressing block 6 is opened on the locking block 71. The locking block 71 is placed between the two inserts 9 and the winding is performed after the assembly is completed. Figure 5 One end of the latch 5 is a pin head 51, and the other end is provided with a socket 52, wherein the pin head 51 has a bevel end 510, and the angle formed by the plane of the bevel end 510 and the horizontal plane is an acute angle, the pin head 51 passes through the pressure block 6, and a pin shaft is arranged in the pressure block 6, one end of the pin head 51 on the latch 5 passes through the top of the pressure block 6, when the latch 5 moves downward, the bevel end 510 gradually slides with the pin shaft so that the pressure block 6 slides outward, at this time, the pressure block 6 is disengaged from the slot 710, and the upper cover 7 is taken out; after the latch 5 is pushed up, the inclined surface end 510 gradually disengages from the pin shaft, and the pressure block 6 slides inward. At this time, the pressure block 6 gradually engages with the slot 710, and the upper cover 7 is locked so as to be wound again. Since a spring 10 is sleeved on one end of the plug hole 52 on the latch 5 and is elastically connected to the fixture base 2, the plug shaft on the machine can quickly press down or lift the latch 5 after passing through the plug hole 52, so as to quickly control it.

[0025] In addition, see Figure 1 The opening and closing fixture also includes a mounting plate 11, a motor 12 and a sensor 13. The fixture base 2 and the motor 12 are respectively mounted on both sides of the mounting plate 11, and the motor 12 is driven and connected to the fixture base 2, thereby driving the fixture base 2 to rotate. A positioning plate 14 is fixedly provided on the fixture base 2. The controller is fixedly mounted above the mounting plate 11 for positioning and identifying the positioning plate 14. The sensor 13 and the motor 12 are both connected to an external controller. When the sensor 13 senses that the positioning plate 14 is in the sensing area, the controller commands the motor 12 to pause. At this time, the latch 5 is pulled down to take out the coil 1. After the upper cover plate 7 is assembled and locked, it reaches the winding station again, and then controls the motor 12 to rotate to perform the winding action.

[0026] The advantages of the present invention are:

[0027] The opening and closing clamp has a simple overall structure, is easy to assemble, has a low manufacturing cost, and saves investment costs.

[0028] The structure is compact and ingenious. The upper cover can be disassembled and locked by controlling the latch to slide up and down. Therefore, the coil can be quickly taken out after the rubber coating is completed, and the upper cover can be quickly assembled and locked to repeat the process cycle, shortening the connection time between processes and improving production efficiency. After the latch is pulled down, the inclined end of the pin head and the pin shaft produce a sliding fit, and the pressure block slides outward under pressure to disengage from the slot. The upper cover is quickly disassembled and the coil is taken out. After the upper cover is installed again, the latch is lifted and slides upward, and the pressure block slides inward and is inserted into the slot to quickly lock the upper cover and repeat the process. The use and control are convenient and fast, which greatly improves production efficiency.

[0029] It is known from common technical knowledge that the present invention can be implemented by other embodiments that do not deviate from its spirit and essential features. Therefore, the above disclosed embodiments are only illustrative in all respects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
