Description

Technical Field

[0001] The utility model relates to the field of automatic production equipment for washing machines, in particular to automatic bearing assembly and glue dispensing equipment for a rear drum cover of a washing machine. Background Art

[0002] The back cover of a washing machine is an important component of the washing machine. Its main function is to seal the internal space of the washing machine. It is responsible for keeping the internal environment of the washing machine clean and dry, while preventing water, detergent and other dirt from overflowing during the washing process, and effectively protecting the internal parts of the washing machine from damage. In addition, as part of the washing machine structure, the back cover also provides additional support and stability to ensure that the entire washing machine is stable and reliable during operation.

[0003] In the manufacturing process of the rear drum cover of the washing machine, the screw locking of the bearing is a crucial process. This step is directly related to the tight connection between the rear drum cover and the bearing, which in turn affects the service life and safety of the entire washing machine. However, this process currently relies mainly on manual operation, which has some potential problems and hidden dangers.

[0004] First, since screwing is a manual operation, the operator's technical level and strength control vary, resulting in some screws not being securely locked or being over-tightened. Second, when manually dispensing glue, the size and uniformity of the glue dots may vary. Some screws may have too many glue dots, while others may have insufficient glue dots, affecting the fixing effect of the bearing. In addition, under the vibration and vibration generated when the washing machine is working, if the screws are not securely locked or the glue dots are insufficiently fixed, there is a great risk of the screws loosening, which may cause the rear cover to separate from the bearing, or even damage other parts.

[0005] Therefore, it is necessary to introduce automated equipment to improve production efficiency and product quality and reduce defective rates and safety hazards. Utility Model Content

[0032] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods: Figures 1 to 11The bearing automatic assembly and dispensing equipment of the rear drum cover of a washing machine shown in the figure includes a conveyor frame 1, on which a material conveyor line 11 capable of conveying the rear drum cover 10 of the washing machine is arranged, and the material conveyor line 11 is composed of two parallel and spaced conveyor belts. Since the rear drum cover 10 of the washing machine is directly removed from the injection molding machine by the manipulator of the injection molding machine, a material receiving plate 9 capable of lifting upward from the center of the material conveyor line 11 is arranged on the conveyor frame 1, and a material receiving lifting cylinder 91 capable of driving the material receiving plate 9 to lift up and down is arranged on the conveyor frame 1. When the rear drum cover 10 of the washing machine is removed by the manipulator of the injection molding machine and transferred to the upper part of the material conveyor line 11, the material receiving lifting cylinder 91 drives the material receiving plate 9 to move upward to receive the rear drum cover 10 of the washing machine above, and then the material receiving lifting cylinder 91 drives the material receiving plate 9 to support the rear drum cover 10 of the washing machine and finally allows the rear drum cover 10 of the washing machine to fall onto the material conveyor line 11. It should be noted that, since the washing machine rear drum cover 10 is still in a high temperature state after being removed from the injection molding machine, a cooling device 8 is provided at the middle section of the conveyor frame 1 located on one side of the material receiving plate 9, which can cover the material conveying line 11 and cool the washing machine rear drum cover on the material conveying line 11. The cooling device 8 includes an outer cover 81 covering the material conveying line 11, and a plurality of cooling fans 82 capable of blowing air downward are provided on the top of the outer cover 81. An equipment support bracket 3 is provided at the end of the conveyor frame 1. The equipment support bracket 3 is a rectangular frame-shaped box. An external protection frame 36 in the form of a frame can be installed on the top of the equipment support bracket 3 to protect the equipment carried on the equipment support bracket 3 and isolate personnel to prevent injuries. The end of the material conveying line 11 extends to the upper side of one side of the equipment carrying bracket 3, a rotatable turntable 2 is provided in the center of the equipment carrying bracket 3, a first rotating motor 20 capable of driving the turntable 2 to rotate is provided on the top surface of the equipment carrying bracket 3, a gantry 30 spanning the turntable 2 is mounted on the equipment carrying bracket 3, a manipulator guide rail 32 with one end extending to the upper side of the material conveying line 11 is horizontally provided on the gantry 30 located above the turntable 2, a manipulator guide rail 32 with one end extending to the upper side of the material conveying line 11 is provided on the manipulator guide rail 32 near the end of the material conveying line 11, and a manipulator that can move along the manipulator guide rail 32 and can clamp the rear drum cover of the washing machine transmitted from the material conveying line 11 to the turntable A first horizontal walking robot 4 is on the turntable 2, and a plurality of positioning and fixing seats 21 are arranged on the turntable 2 in sequence along the circumference, which can carry and fix the rear drum cover of the washing machine clamped by the first horizontal walking robot 4; an automatic drilling device 5 is arranged on the equipment supporting bracket 3 on one side of the outer edge of the turntable 2, and can drill a hole in the center of the rear drum cover of the washing machine on the positioning and fixing seat 21; a second horizontal walking robot 6 that can move along the robot guide rail 32 is arranged on the robot guide rail 32 on one side of the first horizontal walking robot 4; a screw locking module 61 that can move with the arm and thereby screw in the rear drum cover of the washing machine on the turntable 2 below is arranged on the arm of the second horizontal walking robot 6.Specifically, the overall working rhythm of the utility model is as follows: when the rear drum cover 10 of the washing machine is injection molded, the manipulator of the injection molding machine itself first clamps the rear drum cover 10 of the washing machine out of the injection molding machine and moves it to the top of the material conveying line 11. At this time, the material receiving lifting cylinder 91 is started to drive the material receiving plate 9 to rise to the bottom of the removed rear drum cover 10 of the washing machine, and receive the rear drum cover 10 of the washing machine. Subsequently, the material receiving lifting cylinder 91 drives the material receiving plate 9 to descend again and place the rear drum cover 10 of the washing machine on the material conveying line 11. The material conveying line 11 is turned on, and the rear drum cover 10 of the washing machine is conveyed toward the equipment supporting bracket 3. During the conveying process, the cooling device 8 pre-cools the rear drum cover 10 of the washing machine on the material conveying line 11. When the first rear drum cover 10 of the washing machine moves to the tail end of the material conveying line 11, the first horizontal manipulator 4 will clamp the rear drum cover 10 of the washing machine onto the turntable 2. Among them, such as. Figures 4 to 11 As shown, a second rotary motor 41 capable of moving up, down, left, and right with the arm is provided on the arm of the first horizontal manipulator 4, and the rotating shaft of the second rotary motor 41 is vertically arranged downward, and a support-grab type clamping mechanism 42 capable of expanding outward is provided at the end of the rotating shaft. The first horizontal manipulator 4 lifts and lowers the washing machine rear drum cover 10 by inserting the support-grab type clamping mechanism 42 into the central hole of the bearing of the washing machine rear drum cover 10. It should be noted here that the washing machine rear drum cover 10 and the bearing are integrally injection molded during the injection molding of the washing machine rear drum cover, so the entire washing machine rear drum cover 10 can be lifted only by inserting the support-grab type clamping mechanism 42 into the central hole of the bearing. The support-grab type clamping mechanism 42 is basically the same as the design structure of the prior art, that is, a clamping seat 44 is fixed on the rotating shaft at the bottom of the second rotary motor 41, and the clamping seat 44 is supported outward by an internal support type connecting rod lever or a cylinder direct drive to three support blocks 45 evenly distributed at the bottom of the clamping seat 44 in three equal parts. With this structure, when the arm of the first horizontal robot 4 moves downward with the second rotary motor 41 to the top of the bearing of the rear drum cover 10 of the washing machine, the three support blocks 45 are inserted into the central hole of the bearing of the rear drum cover 10 of the washing machine, and finally the support blocks 45 are pushed open by the cylinder in the clamping seat 44, and the outer wall of the support block 45 is squeezed together with the inner wall of the central hole of the bearing, completing the temporary connection with the rear drum cover 10 of the washing machine. Figures 1 to 11It can be clearly seen that since the edge of the washing machine rear drum cover 10 is not horizontal but has some protruding parts, when placing the washing machine rear drum cover 10 on the turntable 2, the edge with the protruding part needs to be turned to the outside of the turntable 2 to ensure that the washing machine rear drum cover 10 is placed horizontally and stably on the turntable 2. Therefore, an industrial camera 43 is provided at the bottom of the first horizontal walking manipulator 4 on one side of the arm, which can visually identify the washing machine rear drum cover below and then control the second rotating motor 41 to horizontally rotate the supporting and grasping clamping mechanism 42. A fill light 46 is provided around the bottom periphery of the industrial camera 43. After the industrial camera takes a picture and compares it with the preset picture in the system, it sends a signal to the system to control the rotation of the second rotating motor 41, so that the washing machine rear drum cover 10 that has been clamped by the supporting block 45 can be rotated to a suitable horizontal angle. Then the arm of the first transverse manipulator 4 drives the supporting and grasping clamping mechanism 42 to move downward to place the washing machine rear drum cover 10 on the positioning fixing seat 21 on the surface of the turntable 2. After placement, the three supporting blocks 45 are driven to retract again by the cylinder in the clamping seat 44, and the arm of the first transverse manipulator 4 moves upward, and the supporting and grasping clamping mechanism 42 leaves the washing machine rear drum cover 10 at this time, completing the loading work. Then the turntable 2 is driven to rotate by the first rotating motor 20, and the washing machine rear drum cover 10 placed on the positioning fixing seat 21 is transferred to the automatic drilling device 5 station. It needs to be explained again here that the positioning fixing seat 21 on the turntable 2 is arranged at intervals corresponding to each station of the turntable. The structure of the positioning fixing seat 21 in this embodiment is specifically as follows: it includes a protruding positioning plate 22 arranged on the surface of the turntable 2, a through hole 23 that can penetrate the positioning plate 22 and the turntable 2 below is provided in the center of the positioning plate 22, and a plurality of clamping blocks 24 are provided around the through hole 23 on the top of the positioning plate 22, and the clamping blocks 24 are in groups of two, corresponding to the convex ribs on the rear drum cover 10 of the washing machine, and just clamp the convex ribs on the rear drum cover 10 of the washing machine between the corresponding two clamping blocks 24. When the turntable 2 rotates the rear drum cover 10 of the washing machine to the corresponding automatic drilling device 5, the automatic drilling device 5 drills through the water outlet left in the center of the bearing of the rear drum cover 10 of the washing machine. It needs to be explained that, since the injection port (that is, the water outlet) of most rear drum covers 10 of washing machines is injected and molded from the hole of the central bearing during injection molding, the center of the bearing of the rear drum cover 10 of the washing machine is closed after the injection molding, so it needs to be drilled through.The automatic drilling device 5 includes a drilling rig support 51 arranged on the top surface of the equipment carrying support 3, the top of the drilling rig support 51 extends to the top of the positioning fixing seat 21, a drilling rig guide rail 52 is vertically provided on the front side of the top of the drilling rig support 51, a drilling rig slider 53 that can move up and down along the drilling rig guide rail 52 is slidably provided on the drilling rig guide rail 52, a drilling rig fixing seat 54 is provided on one side of the drilling rig slider 53, and a drilling machine 55 with a drill bit downwardly aligned with the central through hole 23 of the positioning fixing seat 21 below is provided on a side vertical surface of the drilling rig fixing seat 54, a first servo motor 56 is provided on the back of the top of the drilling rig support 51, a screw sleeve (not shown in the figure) is fixed to the back of the drilling rig fixing seat 54, a screw 57 is vertically penetrated in the screw sleeve, and the motor shaft of the first servo motor 56 is connected to the top of the screw 57 by a drilling rig lifting belt 58. The first servo motor 56 drives the screw rod 57 to rotate, and the drilling machine fixing seat 54 moves up and down, and the drilling machine 55 rises and falls synchronously with the drilling machine fixing seat 54 to drill through the central hole of the bearing of the washing machine rear drum cover 10. In order to prevent the washing machine rear drum cover 10 from deviating from the position or sliding off the positioning fixing seat 21 due to vibration during the drilling process, as shown. Fig. 9 and Fig.11 As shown in the figure, elastic pressure rods 59 are movably provided on the drill fixing seats 54 on the left and right sides of the drilling machine 55, respectively, which can press the rear drum cover of the washing machine below. The waste material drilled through the central hole of the bearing of the rear drum cover 10 of the washing machine slides out from the bottom end of the equipment support bracket 3 to the waste chute 34 outside the equipment support bracket 3 and is collected. Specifically, a guide pipe 35 is provided between the equipment support bracket 3 and the turntable 2 below the drilling machine 55, which can guide the waste material drilled by the drilling machine 55 on the rear drum cover of the washing machine below from the through hole 23 on the positioning plate 22 into the waste chute 34. The waste pieces generated by drilling will fall into the guide pipe 35 along the through hole 23 on the positioning plate 22. The guide pipe 35 is connected to the top of the waste chute 34, so the waste pieces will eventually enter the waste chute 34 along the guide pipe 35 until they are guided into the collection frame. The rear drum cover 10 of the washing machine that has been drilled will be brought by the turntable 2 to the station under the second horizontal manipulator 6 again, and the screw locking module 61 will be used to screw the bearing into the screws to strengthen the fixation. It should be noted that the screw locking module 61 in this embodiment adopts the existing blowing type screw locking machine, and the blowing type screw locking machine is only fixed on the arm of the second horizontal manipulator 6. The blow nail feeder 33 is arranged in the equipment supporting bracket 3 and is connected to the blowing type screw locking machine through a bellows. After the screws are tightened, the rear drum cover 10 of the washing machine can be taken away to the next step of the washing machine production process by manual or external manipulators.

[0033] In addition, if Figures 1 to 11As shown, in order to prevent the screws screwed into the bearing by the screw locking module 61 from loosening during the vibration of the washing machine, a glue dispensing mechanism 7 is provided on the gantry 30 on one side of the screw locking module 61, which can dispense glue on the screws before the screw locking module 61 is screwed into the screws. The glue dispensing mechanism 7 includes a connecting arm 71 rotatably mounted at the bottom of the gantry 30, a glue cylinder mounting frame 72 capable of mounting a glue cup for fixing the screw glue is fixed on the connecting arm 71, a glue squeezing cylinder 73 capable of squeezing the glue cup on the glue cylinder mounting frame 72 is provided on the connecting arm 71 at the rear end of the glue cylinder mounting frame 72, a glue dispensing head 74 is provided at the head end of the glue cylinder mounting frame 72, and a glue connecting plate 75 capable of extending to the bottom of the glue dispensing head 74 is provided at the bottom of the connecting arm 71.

[0034] In addition, if Figures 1 to 3 As shown in the figure, a controller 100 and a display screen 101 are also provided on the external protection frame 36. The operator can use the controller 100 to control the automatic assembly of the bearings of the entire washing machine rear barrel cover and the operation and shutdown of the dispensing equipment, and can also control the rhythm coordination between the various components during operation. An alarm light 102 is also provided on the controller 100. When the washing machine rear barrel cover 10 and the bearing are assembled, the alarm light 102 lights up, and the operator can remove the washing machine rear barrel cover 10 from the turntable 2, or when there is a problem with the rhythm or individual devices, the operator can be reminded to make adjustments. The display screen 101 can display various states of the entire device, allowing each step parameter to be visualized.
