Description

Technical Field

[0001] The utility model relates to the technical field of automatic assembly equipment, in particular to an automatic sponge ring gear assembly machine. Background Art

[0002] The toner cartridge used in printers and copiers has a gear 11 on its side. The gear 11 is used to receive the driving force for rotating the toner supply and development structure of the toner cartridge, such as the photosensitive drum, the developing roller, and the stirring frame. Therefore, the rotating shaft 111 of the gear 11 is rotatably supported on the side of the toner cartridge. In order to improve the sealing performance of the toner cartridge's powder bin, a sponge ring 12 is mounted on the rotating shaft 111 of the gear 11. Figures 1 to 3 shown.

[0003] In order to assemble the sponge ring 12 onto the rotating shaft 111 of the gear 11, a sponge ring assembly machine is currently provided with a transmission group for conveying the gear 11, a feeding group for conveying the sponge ring 12 and a manipulator on the frame, and a retention component that can intercept and limit the gear 11 is provided on the frame, and the manipulator can flush the cotton core of the sponge ring 12, and can transfer the sponge ring 12 after the cotton core is flushed and put it on the gear 11 intercepted by the retention component, wherein the manipulator includes a support frame, a sliding seat that can be slidably mounted on the support frame, and a support frame provided on the support frame. The output end of the sliding seat can be extended and retracted in the vertical direction. The flushing group includes a telescopic cylinder arranged on the sliding seat and a chuck arranged on the output end of the telescopic cylinder for clamping the sponge ring 12. The output end of the telescopic cylinder is arranged downward, and a retractable punch is arranged at the center of the chuck. The telescopic cylinder can drive the chuck to extend and retract up and down. In addition, the punch is inserted in the middle of the chuck, and another driving motor or elastic structure is used to make the punch move relative to the chuck. The chuck consists of two openable and closable clips, and the opening and closing are controlled by a motor.

[0004] However, the robot arm of the existing sponge ring assembly machine controls two openable and closable clips to be inserted into the cotton core hole 121 of the sponge ring 12, and controls the two clips to open to clamp the sponge ring 12 through a motor. Since the material of the sponge ring 12 itself has elasticity, the clamping force of the two clips clamping the sponge ring 12 is uneven, causing the sponge ring 12 clamped by the two clips to be tilted and offset. When the sponge ring 12 is mounted on the rotating shaft 111 of the gear 11, the central axis of the cotton core hole 121 of the sponge ring 12 and the rotating shaft 111 of the gear 11 are offset and difficult to align, thereby affecting the smoothness of the operation of the sponge ring 12 mounted on the rotating shaft 111 of the gear 11, and affecting the assembly efficiency and assembly quality. In addition, during the manufacturing process of the rotating shaft 111 of the gear 11, due to the injection molding demoulding manufacturing process, the outer periphery of the rotating shaft 111 is set in a conical shape in its axial direction, that is, one end of the rotating shaft 111 is a small diameter end 1111, and the other end of the rotating shaft 111 is a large diameter end 1112. In order to ensure the sealing effect, the aperture of the cotton core hole 121 of the sponge ring 12 is larger than the small diameter end 1111 of the rotating shaft 111, and the aperture of the cotton core hole 121 of the sponge ring 12 is smaller than the large diameter end 1112 of the rotating shaft 111. However, the manipulator of the existing sponge ring assembly machine is only The sponge ring 12 can be mounted on the small diameter end 1111 of the rotating shaft 111. In order to press the cotton core hole 121 of the sponge ring 12 onto the large diameter end 1112 of the rotating shaft 111 for interference fit so as to assemble the sponge ring 12 on the rotating shaft 111, it is necessary to additionally control the pressing head through a pressing device to press the cotton core hole 121 of the sponge ring 12 onto the large diameter end 1112 of the rotating shaft 111 for interference fit. This requires material transportation and pressing operations between the pressing device and the existing sponge ring assembly machine, which increases the process steps and greatly reduces the assembly efficiency.

[0005] In order to achieve the main purpose of the utility model, the utility model provides a sponge ring gear automatic assembly machine with high automation, good assembly quality and high assembly efficiency.

[0006] In order to achieve the main purpose of the utility model, the utility model provides a sponge ring gear automatic assembly machine, including a support seat, a press-fit assembly mechanism and a positioning and unloading mechanism, the positioning and unloading mechanism includes a transmission arm and a transmission control mechanism, the transmission arm is located above the support seat in the vertical direction, and the transmission arm is provided with a positioning groove, the transmission control mechanism can control the transmission arm to move in the horizontal direction, so that the positioning groove switches between a limited position and a unloading position; in the limited position, the positioning groove moves to the top of the support seat and forms a limiting area with the top end surface of the support seat, and the limiting area is used to place the gear; in the unloading position, the positioning groove moves to the support seat, and the positioning groove moves to the support seat. The outside of the support seat; the press-fitting assembly mechanism includes a moving control mechanism, a moving seat, a press-fitting control mechanism, a press-fitting column, a telescopic control mechanism and a material picking column, the moving control mechanism can control the moving seat to move in the horizontal direction, the press-fitting control mechanism is arranged on the moving seat and can control the press-fitting column to move in the vertical direction, the press-fitting end of the press-fitting column can be pressed against the sponge ring; the telescopic control mechanism is arranged on the press-fitting column and can control the material picking column to move in the vertical direction, the material picking end of the material picking column can pass through the press-fitting end of the press-fitting column and be inserted into the core hole of the sponge ring, and the material picking end of the material picking column is provided with multiple vacuum suction nozzles, and the multiple vacuum suction nozzles are evenly distributed on the circumference of the material picking column.

[0007] It can be seen from the above scheme that in the assembly process of the sponge ring gear automatic assembly machine of the utility model in which the sponge ring is pressed onto the rotating shaft of the gear, the transmission control mechanism of the positioning and unloading mechanism of the sponge ring gear automatic assembly machine controls the transmission arm to move in the horizontal direction to just above the support seat and form a limiting area between the top surface of the support seat. At this time, the positioning groove on the transmission arm is in a limited position, thereby limiting the gear within the limited area. At the same time, the movement control mechanism of the pressing and assembling mechanism of the sponge ring gear automatic assembly machine controls the moving seat to drive the pressing control mechanism, the pressing column, the telescopic control mechanism and the material taking column to move horizontally. The material collecting column moves in the vertical direction so that the material collecting column is located directly above the core hole of the sponge ring. Then the press-fitting control mechanism controls the press-fitting column to drive the telescopic control mechanism and the material collecting column to move downward in the vertical direction. The telescopic control mechanism controls the material collecting column to move in the vertical direction so that the material collecting end of the material collecting column passes through the press-fitting end of the press-fitting column and is inserted into the core hole of the sponge ring. Since the material collecting end of the material collecting column is provided with a plurality of vacuum suction nozzles, the plurality of vacuum suction nozzles are evenly distributed in the circumferential direction of the material collecting column, so that the material collecting end of the material collecting column steadily adsorbs the sponge ring on the material collecting end of the material collecting column through the vacuum suction nozzle. Then the moving control mechanism controls the moving seat The press-fitting control mechanism, the press-fitting column, the telescopic control mechanism, the material-taking column and the sponge ring are driven to move in the horizontal direction to just above the limiting area. Then the press-fitting control mechanism controls the press-fitting column to drive the telescopic control mechanism, the material-taking column and the sponge ring to move in the vertical direction toward the rotating shaft of the gear in the limiting area. When the core hole of the sponge ring is accurately sleeved on the small-diameter end of the rotating shaft of the gear, the material-taking end of the material-taking column cancels the vacuum adsorption of the sponge ring, and the telescopic control mechanism controls the material-taking column to move in the vertical direction so that the material-taking column withdraws from the core hole of the sponge ring and retracts into the press-fitting column. Continuously moving downward in the vertical direction, the press-fitting end of the press-fitting column presses against the sponge ring on the small diameter end of the rotating shaft of the gear, and the press-fitting control mechanism controls the press-fitting column to continue to move downward in the vertical direction, so that the sponge ring is press-fitted to the large diameter end of the rotating shaft of the gear through interference fit, and the gear and the sponge ring in the limit area are assembled. After that, the transmission control mechanism controls the transmission arm to move in the horizontal direction, so that the positioning groove on the transmission arm moves to the unloading position, that is, the positioning groove moves to the outside of the support seat, and the positioning groove synchronously drives the assembled sponge ring and gear to move out of the support seat for unloading operation. Therefore, the utility model sponge ring gear automatic assembly machine can put the sponge ring on the rotating shaft of the gear and press-fit it to the large diameter end of the rotating shaft of the gear through interference fit, without the need for additional press-fitting equipment, thereby reducing the assembly production cost, reducing the process steps, and improving the assembly efficiency. In addition, the assembly operation of the utility model sponge ring gear automatic assembly machine is fully automated, and the degree of automation is high, so that the assembly efficiency is high.In addition, when the sponge ring gear automatic assembly machine of the utility model performs the feeding operation on the elastic sponge ring, the feeding end of the feeding column is controlled to pass through the pressing end of the pressing column and be inserted into the core hole of the sponge ring. Since the feeding end of the feeding column is provided with multiple vacuum suction nozzles, the multiple vacuum suction nozzles are evenly distributed on the circumference of the feeding column, so that the feeding end of the feeding column can stably adsorb the elastic sponge ring on the feeding end of the feeding column through the vacuum suction nozzle, and the vacuum adsorption force on the circumference of the elastic sponge ring is uniform, thereby avoiding the tilting and offset of the sponge ring, so that the central axis of the elastic sponge ring can be coaxially aligned when it is mounted on the rotating shaft of the gear, so that the operation of mounting the elastic sponge ring on the rotating shaft of the gear is smooth, and the elastic sponge ring will not be deformed, so that the assembly quality of the sponge ring and the rotating shaft of the gear is good, thereby improving the assembly quality.

[0030] See also Figures 4 to 12This embodiment discloses a sponge ring gear automatic assembly machine 20, including a support seat 21, a press-fit assembly mechanism and a positioning and unloading mechanism. The positioning and unloading mechanism includes a transmission arm 22 and a transmission control mechanism 23. The transmission arm 22 is located above the support seat 21 in the vertical direction, and the transmission arm 22 is provided with a positioning slot 226. The transmission control mechanism 23 can control the transmission arm 22 to move in the horizontal direction so that the positioning slot 226 switches between a limited position and an unloading position. In the limited position, the positioning slot 226 moves to the top of the support seat 21 and forms a limiting area with the top surface of the support seat 21. The limiting area is used to place the gear 11; in the unloading position, the positioning slot 226 moves to the outside of the support seat 21. At the same time, the press-fit assembly mechanism of this embodiment includes a moving control mechanism 27, a moving seat 229, a press-fit control mechanism 26, a press-fit column 25, a telescopic control mechanism and a material extraction column 231. The moving control mechanism 27 can control the moving seat 229 to move in the horizontal direction. The press-fit control mechanism 26 is arranged on the moving seat 229 and can control the press-fit column 25 to move in the vertical direction. The press-fit end of the press-fit column 25 can press against the sponge ring 12. In addition, the telescopic control mechanism of this embodiment is arranged on the press-fit column 25 and can control the material extraction column 231 to move in the vertical direction. The material extraction end of the material extraction column 231 can pass through the press-fit end of the press-fit column 25 and be inserted into the core hole 121 of the sponge ring 12. The material extraction end of the material extraction column 231 is provided with a plurality of vacuum suction nozzles 2311, and the plurality of vacuum suction nozzles 2311 are evenly distributed in the circumferential direction of the material extraction column 231.

[0031] In the assembly process of the sponge ring 12 being pressed onto the rotating shaft 111 of the gear 11 by the sponge ring gear automatic assembly machine 20 of this embodiment, the transmission control mechanism 23 of the positioning and unloading mechanism of the sponge ring gear automatic assembly machine 20 controls the transmission arm 22 to move in the horizontal direction to just above the support seat 21 and form a limiting area between the top surface of the support seat 21. At this time, the positioning groove 226 on the transmission arm 22 is in a limited position, thereby limiting the gear 11 in the limited area. At the same time, the movement control mechanism 27 of the pressing and assembling mechanism of the sponge ring gear automatic assembly machine 20 controls the moving seat 229 to drive the pressing control mechanism 26, the pressing column 25, the telescopic control mechanism and the material taking column 231 to move in the horizontal direction, so that the material taking column 231 is located above the sponge ring 1 2, then the press-fitting control mechanism 26 controls the press-fitting column 25 to drive the telescopic control mechanism and the material taking column 231 to move downward in the vertical direction, and the telescopic control mechanism controls the material taking column 231 to move in the vertical direction, so that the material taking end of the material taking column 231 passes through the press-fitting end of the press-fitting column 25 and is inserted into the core hole 121 of the sponge ring 12. Since the material taking end of the material taking column 231 is provided with a plurality of vacuum suction nozzles 2311, the plurality of vacuum suction nozzles 2311 are evenly distributed in the circumferential direction of the material taking column 231, so that the material taking end of the material taking column 231 steadily adsorbs the sponge ring 12 on the material taking end of the material taking column 231 through the vacuum suction nozzles 2311, and then the moving control mechanism 27 controls the moving seat 229 to drive the press-fitting control mechanism 26 and the press-fitting control mechanism 25 to move downward in the vertical direction, and the telescopic control mechanism controls the material taking column 231 to move in the vertical direction, so that the material taking end of the material taking column 231 passes through the press-fitting end of the press-fitting column 25 and is inserted into the core hole 121 of the sponge ring 12. The column 25, the telescopic control mechanism, the material collection column 231 and the sponge ring 12 move in the horizontal direction to the top of the limiting area, and then the press-fitting control mechanism 26 controls the press-fitting column 25 to drive the telescopic control mechanism, the material collection column 231 and the sponge ring 12 to move in the vertical direction toward the rotating shaft 111 of the gear 11 in the limiting area. When the core hole 121 of the sponge ring 12 is accurately sleeved on the small diameter end 1111 of the rotating shaft 111 of the gear 11, the material collection end of the material collection column 231 cancels the vacuum adsorption of the sponge ring 12, and the telescopic control mechanism controls the material collection column 231 to move in the vertical direction so that the material collection column 231 withdraws from the core hole 121 of the sponge ring 12 and retracts into the press-fitting column 25, accompanied by the press-fitting control mechanism 26 controlling the press-fitting column 25 in the vertical direction. As the gear 11 continues to move downward, the pressing end of the press-fitting column 25 presses against the sponge ring 12 on the small-diameter end 1111 of the rotating shaft 111 of the gear 11, and the press-fitting control mechanism 26 controls the press-fitting column 25 to continue to move downward in the vertical direction, so that the sponge ring 12 is press-fitted onto the large-diameter end 1112 of the rotating shaft 111 of the gear 11 by interference fit, and the gear 11 and the sponge ring 12 at the limited area are assembled, and then the transmission control mechanism 23 controls the transmission arm 22 to move in the horizontal direction, so that the positioning groove 226 on the transmission arm 22 moves to the unloading position, that is, the positioning groove 226 moves to the outside of the support seat 21, and the positioning groove 226 synchronously drives the assembled sponge ring 12 and gear 11 to move out of the support seat 21 for unloading operation.Therefore, the sponge ring gear automatic assembly machine 20 of the present embodiment is capable of sleeve the sponge ring 12 on the rotating shaft 111 of the gear 11 and press fit it onto the large diameter end 1112 of the rotating shaft 111 of the gear 11 with an interference fit, without the need for additional press-fitting equipment, thereby reducing assembly production costs, reducing process steps, and improving assembly efficiency. Moreover, the assembly operation of the sponge ring gear automatic assembly machine 20 of the present embodiment is fully automated, and the degree of automation is high, making the assembly efficiency high. In addition, when the sponge ring gear automatic assembly machine 20 of the present embodiment performs a feeding operation on the elastic sponge ring 12, the feeding end of the feeding column 231 is controlled to pass through the press-fitting end of the press-fitting column 25 and be inserted into the core hole 121 of the sponge ring 12. Since the feeding end of the feeding column 231 is provided with a plurality of vacuum suction nozzles 2311, and the plurality of vacuum suction nozzles 2311 are evenly distributed in the circumferential direction of the feeding column 231, the feeding end of the feeding column 231 can stably adsorb the elastic sponge ring 12 on the feeding column through the vacuum suction nozzle 2311. At the feeding end of 231, the vacuum adsorption force on the circumference of the elastic sponge ring 12 is uniform, thereby avoiding the tilting and deviation of the sponge ring 12, so that the central axis of the elastic sponge ring 12 can be coaxially aligned when it is mounted on the rotating shaft 111 of the gear 11, so that the operation of the elastic sponge ring 12 being mounted on the rotating shaft 111 of the gear 11 is smooth, and the elastic sponge ring 12 will not be deformed, so that the assembly quality of the sponge ring 12 and the rotating shaft 111 of the gear 11 is good, thereby improving the assembly quality.

[0032] In order to further improve the efficiency of automatic loading of the gear 11, the sponge ring gear automatic assembly machine 20 of this embodiment also includes a first material transfer slide 220, a push rod 221, a push control mechanism 222, a first limit plate 227 and a first limit control mechanism. A feed port 2261 is provided on one side of the positioning groove 226 in the horizontal direction. The first material transfer slide 220 extends in the horizontal direction and docks with the feed port 2261. The push rod 221 is movably located in the first material transfer slide 220. The push control mechanism 222 can control the push rod 221 to move in the extension direction of the first material transfer slide 220. The first material transfer slide 220 is used to place the gear 11. The first limit control mechanism can control the first limit plate 227 to move in the vertical direction. The first limit plate 227 can be inserted into the feed port 2261 and form a limit area between the positioning groove 226 and the top end surface of the support seat 21. The gear 11 is placed in the first material transfer slide 220, and the push control mechanism 222 controls the push rod 221 to move in the extension direction of the first material transfer slide 220 to push the gear 11 in the first material transfer slide 220 from the inlet 2261 of the positioning groove 226 into the positioning groove 226, and then the first limit control mechanism controls the first limit plate 227 to move in the vertical direction to insert into the inlet 2261 and form a limit area between the positioning groove 226 and the top surface of the support seat 21, so that the gear 11 is limited to be positioned in the limit area, so that in the process of fitting the sponge ring 12 on the gear 11 in the limit area, the gear 11 is simultaneously loaded into the first material transfer slide 220 for waiting, which speeds up the loading rhythm and improves the assembly efficiency. Specifically, the push control mechanism 222 of this embodiment is a cylinder, and the first limit control mechanism is a cylinder.

[0033] In order to further improve the efficiency of automatic feeding of the gear 11, the sponge ring gear automatic assembly machine 20 of this embodiment also includes a first vibration disk 211, a second material transfer chute 210, a second limit plate 225 and a second limit control mechanism 228. A feed port 2201 is provided on one side of the first material transfer chute 220 in the horizontal direction. The second material transfer chute 210 extends in the horizontal direction and docks with the feed port 2201. A port of the second material transfer chute 210 away from the first material transfer chute 220 is docked with the first feeding chute 212 of the first vibration disk 211. The gear 11 is placed in the first vibration disk 211. The second limit control mechanism 228 can control the second limit plate 225 to move in the vertical direction. The second limit plate 225 can be inserted into the first material transfer chute 220 and form a positioning area between the push rod 221. The first vibration plate 211 continuously feeds the gear 11 to the second material transfer chute 210 through the first feeding chute 212, and the gear 11 in the second material transfer chute 210 is transported to the first material transfer chute 220 through the feed port 2201. When the sponge ring 12 is installed on the gear 11 in the limit area, the second limit control mechanism 228 controls the second limit plate 225 to move in the vertical direction and insert it into the first material transfer chute 220 and form a positioning area between the push rod 221, so that the gear 11 to be loaded in the first material transfer chute 220 is limited and positioned in the positioning area, so as to prepare for the next loading in the limit area, thereby speeding up the feeding rhythm of the gear 11 and improving the assembly efficiency. Specifically, the second limit control mechanism 228 of this embodiment is a cylinder.

[0034] In order to ensure that the gear 11 is loaded according to the preset swing direction, the top end surface of the first feeding chute 212 of this embodiment is protruding toward the chute and is provided with a first material selection plate 213 and a second material selection plate 214 connected to each other. The first material selection plate 213 is arranged close to the second material transfer chute 210, and the second material selection plate 214 is located in the first vibration disk 211 and protrudes from the first material selection plate 213 toward the chute. During the process of the gear 11 in the first vibration disk 211 entering the first feeding chute 212, when the rotating shaft 111 of the gear 11 is facing downward, the second material selection plate 214 protruding from the first material selection plate 213 and arranged toward the chute will interfere with the upward gear 11 to push the gear 11 with the wrong swing direction out of the first feeding chute 212 and enter the first vibration disk 211 for reloading; when the rotating shaft 111 of the gear 11 is facing upward, the second material selection plate 214 protruding from the first material selection plate 213 and arranged toward the chute will not interfere with the rotating shaft 111, and the gear 11 with the rotating shaft 111 facing upward is transported from the first feeding chute 212 to the second material transfer chute 210, so that only the gear 11 with the correct swing direction is loaded into the second material transfer chute 210, thereby improving the assembly efficiency. Furthermore, in order to ensure that the gear 11 is stably transported in the second material transfer chute 210, the two ends of the top end surface of the second material transfer chute 210 in this embodiment are respectively provided with a first baffle plate 215 and a second baffle plate 216 facing the chute, which can prevent the gear 11 from falling off the second material transfer chute 210.

[0035] In order to ensure the reliability of the feeding of the gear 11, the sponge ring gear automatic assembly machine 20 of this embodiment also includes an in-place detection mechanism, which includes a laser detection head 224 and a lifting control mechanism 223. The laser detection head 224 is located directly above the positioning area in the vertical direction, and the lifting control mechanism 223 can control the laser detection head 224 to move in the vertical direction.
