Description

Technical Field

[0001] This utility model relates to the field of washing machine tripod processing technology, specifically to a finished washing machine tripod packaging production line. Background Technology

[0002] Front-loading washing machines are widely used in the washing machine industry. To ensure stable operation during washing and spin-drying, a tripod is used to fix the inner tub to the rotating shaft. During operation, the motor drives the tripod and inner tub to rotate at high speed, with the tripod providing fixation and support for the inner tub. As a key structural component of the front-loading washing machine, the tripod is integrally die-cast from a central mounting shaft and three legs. The mounting shaft connects to the motor shaft. To prevent damage or contamination of the mounting shaft during transportation, manufacturers typically install protective sleeves on it. Currently, these sleeves are mostly installed manually. After shaping, grinding, and tapping, the die-cast tripod usually requires manual installation of the protective sleeves, which is time-consuming, labor-intensive, and inefficient, hindering automated production. Utility Model Content

[0003] The purpose of this utility model is to overcome the above-mentioned shortcomings and provide a finished packaging production line for washing machine tripods. By setting an outlet positioning frame at the outlet of the parallel belt conveyor, the position of each tripod's legs is made consistent, ensuring that the gripping position of the loading and unloading robot is fixed. This avoids processing errors caused by inconsistent gripping positions of the tripod's legs by the subsequent protective sleeve installation device, and realizes automatic sleeve installation of the tripod shaft. This saves time and effort, frees up labor, and greatly improves the installation efficiency of the protective sleeve, making it suitable for automated production of tripods.

[0004] The purpose of this utility model is achieved as follows:

[0005] A production line for packaging finished washing machine tripods includes a parallel belt conveyor, an outlet positioning frame, and a protective sleeve mounting device arranged sequentially from front to back. The outlet positioning frame is located at the horizontal outlet of the parallel belt conveyor. A loading and unloading robot for clamping the tripod is installed between the outlet positioning frame and the protective sleeve mounting device. The top of the ramp of the outlet positioning frame is close to and lower than the outlet of the parallel belt conveyor. A front limit stop is provided at the bottom of the ramp. A tripod shaft guide channel is provided at the center of the top of the ramp. The tripod shaft guide channel is symmetrically V-shaped and its width is inclined. The direction gradually decreases from high to low. Side limit bars are symmetrically provided on the left and right sides of the tripod shaft guide channel. The protective sleeve installation device includes a worktable. A screw is vertically provided in the center of the worktable. The screw is driven to rotate by a motor. A placement platform is provided on the top of the screw. A nut block is sleeved on the screw. The nut block is hinged to three connecting rods. The other end of each connecting rod is hinged to a clamping inner rod. The clamping inner rod is slidably connected to the clamping outer rod. The clamping outer rod is provided with a clamping block corresponding to the tripod legs. A positioning platform is provided in the center of the placement platform. A positioning hole is provided in the center of the positioning platform. A protective sleeve is preset in the positioning hole.

[0006] Preferably, the V-shaped bottom of the tripod shaft guide channel is set to an arc shape corresponding to the tripod mounting shaft.

[0007] Preferably, the landslide includes a middle beam, side beams and rollers, with two side beams arranged on the left and right sides of the middle beam, and rollers arranged between the side beams and the middle beam, with multiple rollers evenly spaced along the inclination direction of the landslide.

[0008] Preferably, the high end of the side limiting stop is fixed on the side beam, the low end is fixed on the middle beam, the tripod shaft guide channel is set on the middle beam, and the two ends of the roller shaft are rotatably set on the middle beam or the side beam through bearings.

[0009] Preferably, there is a height difference of 5-15cm between the top of the landslide and the discharge port of the parallel belt conveyor, and the landslide forms an angle of 10-30° with the horizontal plane.

[0010] Preferably, the protective sleeve has an upward opening, the tripod's mounting shaft is inserted into the positioning platform of the pre-set protective sleeve, and a downward pressure cylinder is provided directly above the positioning platform.

[0011] Preferably, the bottom of the inner clamping rod and the top of the outer clamping rod are slidably connected to a transverse guide rail, and the vertically arranged inner clamping rod and outer clamping rod move laterally synchronously.

[0012] Preferably, the positioning hole has a protective sleeve through groove extending radially outward, and the inlet of the protective sleeve through groove is connected to the protective sleeve feeding channel.

[0013] Preferably, the feeding channel includes a horizontal channel and an inclined channel. The horizontal channel is located on the extension line of the protective sleeve groove. The lower end of the inclined channel is connected to the horizontal channel. A pushing cylinder is provided at the end of the horizontal channel away from the positioning hole.

[0014] Preferably, the protective sleeve mounting device is also equipped with an oil tank, and the oil tank contains a sponge for absorbing lubricating oil.

[0015] The beneficial effects of this utility model are:

[0016] By setting an outlet positioning frame at the outlet of the parallel belt conveyor, the position of the legs of each tripod is consistent, ensuring that the gripping position of the loading and unloading robot is fixed, and avoiding processing errors caused by inconsistent positions of the legs of the tripod held by the subsequent protective sleeve installation device.

[0017] The loading and unloading robot inserts the tripod clamp into the positioning table. The motor drives the screw to rotate, and the nut block moves downward, pushing the connecting rod, the inner clamping rod, the outer clamping rod, and the clamping block closer to the tripod, thus clamping and fixing the three legs of the tripod. The pressing cylinder presses down to push the tripod, the outer clamping rod, and the clamping block downward simultaneously. At this point, the protective sleeve is installed in place. The pushing cylinder and the pressing cylinder reset, the screw rotates in the opposite direction, and the nut block moves upward, pushing the connecting rod, the inner clamping rod, the outer clamping rod, and the clamping block away from the tripod. The tripod is then removed from the worktable by the loading and unloading robot.

[0018] The export positioning frame, in conjunction with the loading and unloading robot, enables precise positioning and gripping of the tripod, thereby automating the installation of protective sleeves for the tripod shafts. This saves time and effort, frees up labor, and greatly improves the installation efficiency of the protective sleeves, making it suitable for automated tripod production.

Detailed Implementation

[0030] See Figure 1-9 This utility model relates to a production line for packaging finished washing machine tripods, including a parallel belt conveyor line 1, an outlet positioning frame 2, and a protective sleeve installation device 3 arranged sequentially from front to back. The outlet positioning frame 2 is located at the horizontal outlet of the parallel belt conveyor line 1. A loading and unloading robot 4 for clamping the tripod is provided between the outlet positioning frame 2 and the protective sleeve installation device 3. Finished product frames (not shown in the figure) are arranged side by side on the left and right sides of the protective sleeve installation device 3 to facilitate the loading and unloading robot to transfer the tripod with the protective sleeve installed to the finished product frame.

[0031] The outlet positioning frame 2 includes a frame body 2.1, a ramp 2.2, a front limiting stop 2.3, and a side limiting stop 2.4. The top of the frame body 2.1 is provided with the ramp 2.2, the top of which is close to and lower than the discharge port of the parallel belt conveyor 1. The bottom of the ramp 2.2 is provided with the front limiting stop 2.3. A tripod shaft guide channel 2.2.1 is provided at the center of the top of the ramp 2.2. The tripod shaft guide channel 2.2.1 is symmetrically V-shaped, and its width is inclined from... The height gradually decreases from the high end to the low end. The mounting shaft 5.1 of the tripod 5 slides down along the tripod shaft guide channel 2.2.1 under gravity to the V-shaped bottom of the tripod shaft guide channel. The V-shaped bottom of the tripod shaft guide channel 2.2.1 is set to be arc-shaped corresponding to the mounting shaft of the tripod. Side limiting strips 2.4 are symmetrically provided on the left and right sides of the tripod shaft guide channel 2.2.1. The two side limiting strips 2.4 form a V-shaped stop for guiding and limiting the legs 5.2 of the tripod 5. The front ends of the two side limiting strips 2.4 are close to each other.

[0032] The landslide 2.2 forms an angle of 10-30° with the horizontal plane, with a relatively gentle slope, which reduces the sliding speed of the tripod while ensuring its smooth sliding.

[0033] To reduce contact between the tripod 5 and the landslide 2.2 and to minimize tripod wear, the landslide 2.2 is designed with a hollow structure. The landslide 2.2 includes a central beam 2.2.2, side beams 2.2.3, and rollers 2.2.4. Two side beams 2.2.3 are positioned on the left and right sides of the central beam 2.2.2. Rollers 2.2.4 are positioned between the side beams 2.2.3 and the central beam 2.2.2. Multiple rollers 2.2.4 are evenly spaced along the inclination direction of the landslide 2.2. The rollers 2.2.4 are rotatably mounted on either the central beam 2.2.2 or the side beams 2.2.3 via bearings at both ends.

[0034] The high end of the side limiting stop 2.4 is fixed on the side beam 2.2.3, and the low end is fixed on the middle beam 2.2.2. The tripod shaft guide channel 2.2.1 is set on the middle beam 2.2.2.

[0035] The protective sleeve installation device 3 includes a workbench 3.1, a transverse guide rail 3.2, an inner clamping rod 3.3, an outer clamping rod 3.4, a screw 3.5, a nut block 3.6, a connecting rod 3.7, a placement platform 3.8, and a pressing cylinder 3.9. The workbench 3.1 has a vertically positioned screw 3.5 at its center, driven to rotate by a motor 3.10, which is fixed below the workbench 3.1. The top of the screw 3.5 has a placement platform 3.8 for placing a tripod. The nut block 3.6 is fitted onto the screw 3.5. The nut block 3.6 is hinged to multiple connecting rods 3.7. The three connecting rods 3.7 are evenly distributed around the circumference of the nut block 3.6. The other end of each connecting rod 3.7 is hinged to a clamping inner rod 3.3. The clamping inner rod 3.3 is slidably connected to the clamping outer rod 3.4. The clamping outer rod 3.4 is provided with a clamping block 3.11 corresponding to the support leg of the tripod 5. The bottom of the clamping inner rod 3.3 and the top of the clamping outer rod 3.4 are slidably connected to the transverse guide rail 3.2 respectively. The vertically arranged clamping inner rod 3.3 and clamping outer rod 3.4 move laterally synchronously to achieve the clamping of the tripod.

[0036] The placement platform 3.8 has a positioning platform 3.8.1 at its center, and a positioning hole 3.8.1.1 at its center. A protective sleeve 3.12 is placed in the positioning hole 3.8.1.1 with its opening facing upward. The mounting shaft of the tripod 5 is inserted into the positioning platform 3.8.1 of the pre-set protective sleeve 3.12. A pressing cylinder 3.9 is located directly above the positioning platform 3.8.1.

[0037] The positioning hole 3.8.1.1 has a protective sleeve through groove 3.8.1.2 radially outward. The inlet of the protective sleeve through groove 3.8.1.2 is connected to the protective sleeve feeding channel 3.13. The feeding channel 3.13 includes a horizontal channel 3.13.1 and an inclined channel 3.13.2. The horizontal channel 3.13.1 is located on the extension line of the protective sleeve through groove 3.8.1.2. The lower end of the inclined channel 3.13.2 is connected to the horizontal channel 3.13.1. The end of the horizontal channel 3.13.1 away from the positioning hole 3.8.1.1 is provided with a pusher cylinder 3.14. The pusher cylinder 3.14 pushes the protective sleeve 3.12, which slides into the horizontal channel 3.13.1 under gravity, into the positioning hole 3.8.1.1 at the center of the positioning platform.

[0038] To prevent the tripod from being initially unstable, the placement platform 3.8 is equipped with support columns 3.8.2 corresponding to the three legs of the tripod in the circumferential direction.

[0039] To prevent oxidation and rust on the mounting shaft surface of the tripod, an oil sump 3.15 is also provided on the protective sleeve mounting device 3, and the oil sump 3.15 is equipped with a sponge to absorb lubricating oil.

[0040] Working principle:

[0041] After shaping, grinding, and tapping, the tripod is picked up by the loading and unloading robot and placed onto the parallel belt conveyor line 1 for automatic product packaging. The mounting shaft 5.1 of the tripod 5 faces downwards (the end of the mounting shaft 5.1 contacts the belt). When the tripod 5 reaches the discharge port, there is a 5-15cm height difference between the top of the slide 2.2 and the discharge port. The tripod 5 falls onto the slide due to gravity, and the mounting shaft 5.1 enters the tripod shaft guide channel 2.2.1 and descends along the slide. Under the limiting action of the side limiting strips 2.4, the positions of the three legs of the tripod 5 are adjusted. One of the legs of the tripod is limited on both sides between the front ends of the two side limiting strips 2.4, and the front end of the leg is limited by the front limiting strip 2.3. The other two legs are in contact with the side limiting strips 2.4 respectively, so that the positions of the legs of each tripod are consistent, ensuring that the gripping position of the loading and unloading robot is fixed, and avoiding the processing error caused by the inconsistent gripping position of the tripod legs by the subsequent protective sleeve installation device.

[0042] After the loading and unloading robot picks up the tripod from the exit positioning frame, the mounting shaft of the tripod is first inserted into the oil sump. The mounting shaft squeezes the sponge to apply oil. The oil film can isolate air and moisture and prevent the shaft surface from oxidizing and rusting.

[0043] The loading / unloading robot clamps the tripod 5 and inserts it into the positioning table 3.8.1. The motor 3.10 drives the screw 3.5 to rotate, and the nut block 3.6 moves downward, pushing the connecting rod 3.7, the inner clamping rod 3.3, the outer clamping rod 3.4, and the clamping block 3.11 closer to the tripod 5, thus clamping and fixing the three legs of the tripod. The pressing cylinder 3.9 presses down and pushes the tripod 5, the outer clamping rod 3.4, and the clamping block 3.11 downward simultaneously. At this point, the protective sleeve 3.12 is installed in place. The pushing cylinder 3.14 and the pressing cylinder 3.9 reset, the screw 3.5 rotates in the opposite direction, and the nut block 3.6 moves upward, pushing the connecting rod 3.7, the inner clamping rod 3.3, the outer clamping rod 3.4, and the clamping block 3.11 away from the tripod 5. The tripod is then removed from the worktable by the loading / unloading robot.

[0044] In addition to the above embodiments, this utility model also includes other implementation methods. All technical solutions formed by equivalent transformation or equivalent substitution should fall within the protection scope of the claims of this utility model.
