Description

Technical Field

[0001] This utility model relates to the field of automatic assembly machine technology, and in particular to an automatic assembly machine for waterproof plugs for plastic casings of household appliances. Background Technology

[0002] In the modern home appliance manufacturing industry, the waterproof performance of a product is one of the key indicators for measuring its quality and reliability. To ensure that home appliances can operate normally and stably in various humid environments, waterproofing the plastic casing of the appliances is crucial, and the installation of waterproof plugs is an indispensable part of this process. With the continuous expansion of the home appliance market and the increasing demands of consumers for product quality, home appliance manufacturers face the dual pressure of improving production efficiency and ensuring product quality.

[0003] Currently, although some simple tooling assists manual assembly, it only reduces labor intensity to a certain extent and cannot fundamentally solve the problems of assembly efficiency and quality. For example, in the process of continuous automatic assembly of waterproof plugs by machine, users need to align all the waterproof plugs in advance to facilitate the picking and installation by the robotic arm. This makes the machine less practical in use. Therefore, an automatic assembly machine for waterproof plugs for plastic shells of household appliances was designed. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an automatic assembly machine for waterproof plugs for plastic casings of household appliances.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An automatic assembly machine for waterproof plugs for household appliance plastic shells includes a workbench. An L-shaped support plate is fixedly connected to one end of the top of the workbench. A material bucket is fixedly connected to the top of the L-shaped support plate. A top plate is fixedly connected to the top of the material bucket. A cover plate is rotatably connected to one side of the top plate. A rotating shaft is rotatably fitted onto the top plate at the center of the material bucket. A circular hole adapted to the rotating shaft is opened in the middle of the top plate. A fourth synchronous wheel is fixedly connected to the top of the rotating shaft. Multiple actuating rods are fixedly connected at equal intervals to the rotating shaft inside the material bucket. The bottom of the material bucket is conical, and grooves are opened on both sides of the bottom of the material bucket. The grooves ensure that the waterproof plug can be smoothly exited through the placement hole. A nozzle is fixedly embedded at the bottom of the material bucket at an angle. A rotating rod is rotatably fitted onto the top of the workbench near the material bucket. A circular hole adapted to the rotating rod is opened on the top of the workbench. A turntable is fixedly connected to the top of the rotating rod, and four placement holes are equidistantly opened on the top edge of the turntable, and the placement holes are adapted to the bottom of the material bucket.

[0007] Preferably, a rotating rod is rotatably sleeved on the top of the L-shaped support plate, a round hole adapted to the rotating rod is opened on the top of the L-shaped support plate, a second synchronous pulley is fixedly connected to the top of the rotating rod, and the same first synchronous belt is sleeved between the second synchronous pulley and the fourth synchronous pulley, and a third synchronous pulley is fixedly connected to the bottom of the rotating rod.

[0008] Preferably, the rotating rod is also fixedly fitted with a first synchronous pulley at the top of the worktable, and the first synchronous pulley and the third synchronous pulley are fitted with the same second synchronous belt.

[0009] Preferably, a U-shaped frame is fixedly connected to the top of the workbench, and the U-shaped frame is located at the upper corner of the turntable. An infrared transmitter is fixedly connected to the bottom inner side of the U-shaped frame, and a receiver is fixedly connected to the top inner side of the U-shaped frame. The infrared transmitter is adapted to the placement hole.

[0010] Preferably, the rotating rod is fixedly connected to a rotating plate at the bottom of the workbench, and four straight grooves are equally spaced on the edge of the rotating plate, and a first arc-shaped groove is formed on the edge of the rotating plate between two straight grooves.

[0011] Preferably, a mounting bracket is fixedly connected to the bottom of the workbench near the rotating plate, and a servo motor is fixedly connected to the bottom of the mounting bracket. A disc is fixedly connected to the top output end of the servo motor through the mounting bracket, and the disc is adapted to the first arc-shaped groove. A second arc-shaped groove is opened on one side of the disc, and the second arc-shaped groove is adapted to the rotating plate. A crossbar is fixedly connected to the bottom of the disc near the second arc-shaped groove, and a protruding rod is fixedly connected to the other end of the top of the crossbar, and the protruding rod is adapted to the straight groove. Through the arrangement of the rotating plate, the straight groove, the disc, and the protruding rod, the turntable can rotate a quarter turn for every revolution of the servo motor.

[0012] Preferably, a robotic arm is fixedly connected to the top of the workbench away from the material bucket, and an electric suction cup is fixedly connected to the bottom of the output end of the robotic arm.

[0013] The beneficial effects of this utility model are as follows:

[0014] By employing technologies such as an infrared transmitter and receiver, a servo motor, a turntable, a placement hole, and a rotating plate, the rotation of the turntable causes the actuating rod inside the material bucket to rotate, stirring the waterproof plug. Simultaneously, a high-pressure nozzle adjusts the waterproof plug at the bottom of the bucket. When the rotating placement hole pulls out the waterproof plug, the robotic arm begins to operate; when the placement hole does not pull out the waterproof plug, the servo motor continues to rotate, and the robotic arm does not operate. This effectively solves the problems mentioned in the background technology, thereby achieving precise material handling, reducing the error rate, and improving assembly accuracy through the coordination of the placement hole and the waterproof plug, and the linkage control of the servo motor and robotic arm based on the infrared transmitter and receiver. The robotic arm only operates when the placement hole pulls out the waterproof plug. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figures 1-5 An automatic assembly machine for waterproof plugs for household appliance plastic shells includes a workbench 1. An L-shaped support plate 3 is fixedly connected to one end of the top of the workbench 1. A material hopper 301 is fixedly connected to the top of the L-shaped support plate 3. A top plate 302 is fixedly connected to the top of the material hopper 301. A cover plate 303 is rotatably connected to one side of the top plate 302. A rotating shaft 304 is rotatably fitted onto the top plate 302 at the center of the material hopper 301. A circular hole adapted to the rotating shaft 304 is opened in the middle of the top plate 302. A fourth synchronous wheel 305 is fixedly connected to the top of the rotating shaft 304. Multiple levers are fixedly connected at equal intervals inside the material hopper 301 to the rotating shaft 304. The moving rod 306, the bottom of the material bucket 301 is conical, and the bottom of the material bucket 301 is provided with grooves 308 on both sides. The bottom of the material bucket 301 is fixedly embedded with a nozzle 307 at an angle. The nozzle 307 is connected to the air pump to facilitate the adjustment of the position of the waterproof plug at the bottom of the material bucket 301. The top of the workbench 1 is rotatably fitted with a rotating rod 4 near the material bucket 301. The top of the workbench 1 is provided with a round hole that matches the rotating rod 4. The top of the rotating rod 4 is fixedly connected to a turntable 401, and four placement holes 402 are provided at equal intervals on the top edge of the turntable 401. The placement holes 402 are matched with the bottom of the material bucket 301.

[0023] In this utility model, a rotating rod 5 is rotatably sleeved on the top of the L-shaped support plate 3. A round hole adapted to the rotating rod 5 is opened on the top of the L-shaped support plate 3. A second synchronous wheel 501 is fixedly connected to the top of the rotating rod 5. The same first synchronous belt 502 is sleeved between the second synchronous wheel 501 and the fourth synchronous wheel 305. A third synchronous wheel 503 is fixedly connected to the bottom of the rotating rod 5.

[0024] In this utility model, the rotating rod 4 is also fixedly fitted with a first synchronous pulley 403 at the top of the workbench 1, and the first synchronous pulley 403 and the third synchronous pulley 503 are fitted with the same second synchronous belt 504.

[0025] In this utility model, a U-shaped frame 6 is fixedly connected to the top of the workbench 1, and the U-shaped frame 6 is located at the upper corner of the turntable 401. An infrared transmitter 601 is fixedly connected to the bottom inner side of the U-shaped frame 6, and a receiver 602 is fixedly connected to the top inner side of the U-shaped frame 6. The infrared transmitter 601 is adapted to the placement hole 402. Through the setting of the infrared transmitter 601 and the receiver 602, when the receiver 602 does not detect the signal of the infrared transmitter 601 when the turntable 401 is rotating, the robotic arm 2 can be controlled to work when the turntable 401 stops. Otherwise, the servo motor 701 is controlled to continue rotating one revolution.

[0026] In this utility model, the rotating rod 4 is fixedly connected to the rotating plate 705 at the bottom of the workbench 1. Four straight grooves 706 are equally spaced on the edge of the rotating plate 705, and a first arc-shaped groove is formed between two straight grooves 706 on the edge of the rotating plate 705.

[0027] In this utility model, a mounting bracket 7 is fixedly connected to the bottom of the workbench 1 near the rotating plate 705, and a servo motor 701 is fixedly connected to the bottom of the mounting bracket 7. A disc 702 is fixedly connected to the top output end of the servo motor 701 through the mounting bracket 7, and the disc 702 is adapted to the first arc groove. A second arc groove is opened on one side of the disc 702, and the second arc groove is adapted to the rotating plate 705. A crossbar 703 is fixedly connected to the bottom of the disc 702 near the second arc groove, and a protruding rod 704 is fixedly connected to the other end of the top of the crossbar 703. The protruding rod 704 is adapted to the straight groove 706. Through the shape design of the straight groove 706, the rotating plate 705, the disc 702 and the crossbar 703, the turntable 401 rotates exactly one-quarter of a turn when the servo motor 701 rotates one revolution.

[0028] In this utility model, a robotic arm 2 is fixedly connected to the top of the workbench 1 at the end away from the material hopper 301, and an electric suction cup is fixedly connected to the bottom of the output end of the robotic arm 2. Through the setting of the robotic arm 2, the waterproof plug can be automatically picked up and installed.

[0029] Working principle: In use, the nozzle 307 is connected to the air pump, and the servo motor 701 and the robotic arm 2 are powered. Multiple waterproof plugs are placed into the material bin 301. The servo motor 701 is started to rotate one revolution, causing the disc 702 and the crossbar 703 to rotate one revolution. Under the action of the straight groove 706 and the protruding rod 704, the rotating rod 4, the turntable 401, and the rotating plate 705 rotate one-quarter revolution, thereby causing the placement hole 402 at the bottom of the material bin 301 to move away, and the new placement hole 402 to return to the original position. At the bottom of the material hopper 301, under the action of the second synchronous belt 504, the rotating rod 5, and the first synchronous belt 502, the rotating shaft 304 drives the actuating rod 306 to rotate, causing the waterproof plug inside the material hopper 301 to be actuated. The waterproof plug has a larger upper end and a smaller lower end, and the placement hole 402 is adapted to the smaller end of the waterproof plug. When the turntable 401 rotates continuously, if the placement hole 402 comes out from the bottom of the material hopper 301, it will bring out a waterproof plug. The placement hole 402 at the bottom of the material hopper 301 needs to be adjusted. The servo motor 701 rotates two revolutions, and the turntable 401 rotates half a revolution before it can approach the robotic arm 2. During this process, the placement hole 402 from the material bin 301 will pass through the U-shaped frame 6. When the placement hole 402 reaches one side of the robotic arm 2 through the U-shaped frame 6, if the receiver 602 detects the signal from the infrared transmitter 601, it means that the placement hole 402 has not brought out the waterproof plug. The controller controls the servo motor 701 to continue rotating one revolution, and the turntable 401 to continue rotating a quarter revolution. When the receiver 602 does not detect the signal from the infrared transmitter 601, it means that the placement hole 402 that just approached the robotic arm 2 has a waterproof plug. The robotic arm 2 can then be started to work, and the waterproof plug at that location will be picked up by the suction cup and installed on the nearby appliance shell. At the same time, the nozzle 307 is connected to the air pump. The air pump can work together when the servo motor 701 stops, which is convenient for adjusting the position of the waterproof plug at the bottom of the material bin 301 and preventing the placement hole 402 from not being able to bring out the waterproof plug for a long time.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
