Description

Technical Field

[0001] The utility model relates to the technical field of automated assembly equipment, in particular to an end cover compression spring assembly machine. Background Art

[0002] The toner cartridge for printers and copiers has a compression spring 13 sleeved on the support column 12 of the side end cover 11, so that part of the structure of the toner cartridge has elasticity. In order to firmly sleeve the compression spring 13 on the support column 12, the root of the support column 12 adjacent to the end cover 11 is the large diameter end 122, and the end of the support column 12 away from the end cover 11 is the small diameter end 121, so that the compression spring 13 and the large diameter end 122 of the support column 12 are interference fit, and the compression spring 13 and the small diameter end 121 of the support column 12 are clearance fit, which facilitates the compression spring 13 to be pressed from the small diameter end 121 of the support column 12 to the large diameter end 122 of the support column 12, while ensuring that the compression spring 13 is firmly sleeved on the support column 12, such as Figure 1 shown.

[0003] In order to fit the compression spring 13 onto the support column 12 of the end cover 11, an existing assembly machine clamps the compression spring 13 with a clamping claw, and a press-fitting control mechanism presses the compression spring 13 onto the support column 12 of the end cover 11, thus completing the press-fitting operation of the compression spring 13. However, after the existing assembly machine presses the compression spring 13 onto the support column 12 of the end cover 11, it no longer calibrates and confirms whether the compression spring 13 is pressed into place on the support column 12. Since there is an interference fit between the large diameter end 122 of the support column 12 and the compression spring 13, it is easy for the compression spring 13 and the large diameter end 122 of the support column 12 to be not installed in place, resulting in poor assembly quality of the compression spring 13 and the support column 12 on the end cover 11, thereby affecting the subsequent assembly process of the product, and further affecting the production assembly efficiency.

The two first clamping jaws 236 can clamp the compression spring 13 toward the support column 12 to press the compression spring 13 onto the support column 12. Furthermore, the calibration mechanism 25 of the present embodiment includes a second movable seat 251, a second control mechanism, a rotation control mechanism, a rotating seat 254, a second clamping mechanism 255 and two second clamping jaws 256.

The rotation control mechanism is disposed on the second movable seat 251 and can control the rotating seat 254 to rotate around the horizontal direction. The second clamping mechanism 255 is disposed on the rotating seat 254 and can control the two second clamping jaws 256 to move toward or away from each other. The two second clamping jaws 256 can clamp the compression spring 13 on the support column 12. Specifically, the driving mechanism of the present embodiment is a driving motor 212.

[0031] The driving mechanism of the end cap compression spring assembly machine 20 of this embodiment controls the workbench 21 to rotate in the vertical direction, so that the jig 211 on which the end cap 11 is placed rotates to the press-fitting mechanism 23. Then, the first control mechanism of the press-fitting mechanism 23 controls the first movable seat 234 to move toward the workbench 21 in the horizontal direction. At this time, the first clamping mechanism 235 on the first movable seat 234 controls the two first clamping jaws 236 to move toward each other to clamp the compression spring 13, and the first movable seat 234 moves toward the workbench 21 in the horizontal direction, so that the two first clamping jaws 236 clamp the compression spring 13 toward the support column 12 of the end cap 11 and preliminarily press the compression spring 13 from the small diameter end 121 of the support column 12 to the support column 12. Subsequently, the first clamping mechanism 235 controls the two first clamping jaws 236 to move away from each other to loosen the compression spring 13 preliminarily pressed onto the support column 12, and the first control mechanism controls the first movable seat 234 to move away from the workbench 21 in the horizontal direction to reset. Next, the driving mechanism controls the workbench 21 to rotate in the vertical direction, so that the end cover 11 preliminarily pressed with the compression spring 13 rotates to the calibration mechanism 25, and the second control mechanism of the calibration mechanism 25 controls the second moving seat 251 to move toward the workbench 21 in the horizontal direction, and then the second clamping mechanism 255 controls the two second clamping jaws 256 to move toward each other to clamp the preliminarily pressed compression spring 13 on the support column 12, and then the rotation control mechanism controls the rotating seat 254 to rotate in the horizontal direction, thereby driving the two second clamping jaws 256 to rotate while clamping the compression spring 13, accompanied by The second control mechanism controls the second movable seat 251 to continue to move toward the workbench 21 in the horizontal direction, so that the two second clamping claws 256 clamp the compression spring 13 while rotating, and the compression spring 13 continues to be pressed toward the large diameter end 122 of the support column 12, thereby ensuring that the compression spring 13 is rotated and pressed onto the large diameter end 122 of the support column 12 with interference fit, so as to ensure that the compression spring 13 and the large diameter end 122 of the support column 12 are accurately installed in place, and the compression spring 13 is prevented from falling off from the support column 12, thereby improving the assembly quality of the compression spring 13 and the support column 12 on the end cover 11, so that the assembly quality is good. In addition, the end cover compression spring assembly machine 20 of this embodiment has a high degree of automation, thereby making the production and assembly efficiency efficient.

[0032] In order to ensure the working reliability and stability of the calibration mechanism 25, the calibration mechanism 25 of this embodiment further includes a lifting control mechanism and a lifting rod 259. The lifting control mechanism can control the lifting rod 259 to move in the vertical direction, and the pressing end of the lifting rod 259 can press against the end cover 11. Therefore, before the two second clamps 256 clamp the compression spring 13 for rotation and press-fitting, the lifting control mechanism controls the lifting rod 259 to move downward in the vertical direction so that the pressing end of the lifting rod 259 presses against the end cover 11, thereby pressing and positioning the end cover 11, so that the end cover 11 is kept in a predetermined position, so as to improve the working stability and reliability of the two second clamps 256 clamping the compression spring 13 for rotation and press-fitting. Specifically, the lifting control mechanism of this embodiment is a lifting cylinder 257, the second control mechanism of this embodiment is a second cylinder 251, and the rotation control mechanism of this embodiment is a rotation cylinder 253.

The lifting rod 259 is provided with a sensing rod 2513 at the top end of the upper end of the lifting plate 258. The sensing rod 2513 can be inserted into the sensing slot 2512. When the sensing slot 2512 of the photoelectric sensor 2511 detects that the sensing rod 2513 on the lifting rod 259 has penetrated therein, it means that the pressing end of the lifting rod 259 has pressed and positioned the end cover 11, and the two second clamping jaws 256 can clamp the compression spring 13 for rotation and pressing operation.
