[0047] Please see Figure 1-7 The present invention provides a technical solution: an automatic rotating assembly device for a paste box tray, comprising:

[0048] The workbench 1 has a rotating drive on which a movable platform 11 is provided, and a number of positioning plates 12 are equidistantly arranged along the circumference of the movable platform 11.

[0049] Several auxiliary guide frames 2 are assembled on the positioning plate 12. Each guide frame includes a base 21 and a screw 22 rotatably mounted on the base 21. A paste box 100 is sleeved on the base 21. A screw sleeve 120 of a support plate 110 is screwed onto the screw 22. A connector 23 is provided on the top of the guide frame.

[0050] The pre-inspection station 3 is used for inspecting the ointment box 100 mentioned before assembly;

[0051] Several screwing and pressing stations 4 are arranged at equal intervals along the circumference of the movable platform 11. Screwing and pressing tubes 45 and driving mechanisms for driving the screwing and pressing tubes 45 to rise, fall and rotate are provided on them. The screwing and pressing tubes 45 are sleeved with screws 22 and circumferentially positioned to connect with the connectors 23. Their bottom surfaces abut against the top surface of the support plate 110.

[0052] Post-inspection station 5 is used to inspect the installation depth of the pallet 110 after assembly.

[0053] The assembly device of this invention, through an auxiliary guide frame and a lifting and rotating driven screw-pressing tube, can achieve inner spiral guidance and outer vertical pressing of the tray during the pressing of the tray into the ointment box, ensuring that the tray always slides coaxially relative to the ointment box, thus ensuring that the tray is assembled in place. In use, by driving the screw-pressing tube to rotate, the screw is driven to rotate, which in turn drives the screw sleeve to spirally guide the inner side of the tray. Through the downward pressing movement of the screw-pressing tube and the circumferential limiting of the ointment box on the tray, the tray is stably pressed into the ointment box in a horizontal state. With the cooperation of front and rear inspection stations, the quality of the ointment box and the tray itself, as well as the installation depth, are inspected before and after assembly to ensure high-quality and high-efficiency assembly operations.

[0054] To improve the accuracy of the detection results of parameters such as the shape of the ointment box 100 before assembly, a fixed platform 13 is provided on the inner side of the movable platform 11. The front detection station 3 is mounted on the fixed platform 13, and a sensor corresponding to the number of ointment boxes 100 on a single positioning plate 12 is provided on it.

[0055] In one embodiment, the connector 23 is generally conical, with positioning spring blocks 24 extending on both sides. The positioning spring blocks 24 slide and connect with the guide grooves arranged vertically on the inner wall of the screw-fitting tube 45.

[0056] The driving mechanism includes a first Z-axis driving device 41 and a second Z-axis driving device 43. A first slide block 42 is slidably disposed on the first Z-axis driving device 41, and the second Z-axis driving device 43 is mounted on the first slide block 42. The bottom of the telescopic shaft 431 on the second Z-axis driving device 43 is rotatably connected to the screw-pressing tube 45.

[0057] The drive mechanism also includes a screwing device 44, which includes a power supply device at the top and a drive base 441. An energized coil 442 is provided inside the drive base 441. A screwing and pressing tube 45 passes through the energized coil 442 and contains a magnet. A wire is led out from the terminal block 443 at the bottom of the power supply device and is connected to the energized coil 442.

[0058] At least two first sensors 432 are provided on the second Z-axis drive device 43. The first sensors 432 are used to sense the position of the upper end of the telescopic shaft 431.

[0059] A pair of second sensors 46 are provided on the first slide block 42. The second sensors 46 are set at the same height and are used to sense the position of the telescopic shaft 431 and the screw-pressing tube 45.

[0060] The working principle of the automatic rotating assembly device for a paste box tray in this embodiment includes: During assembly, at the manual loading station, the positioning plate 12, auxiliary guide 2, and paste box 100 are manually positioned, and then the tray 110 is pressed into the inner cavity of the paste box 100. The screw sleeve 120 is connected to the screw 22 for preliminary assembly of the tray 110. The movable platform 11 rotates, transferring the parts to be assembled to the pre-inspection station 3. Sensors on the platform perform pre-assembly inspection of the paste box 100 and the tray 110, and defective products are marked to skip the subsequent assembly process and be collected centrally. The parts to be assembled continue... The transportation process involves moving several pallets 110 sequentially to the bottom of the screw-pressing tube 45 at the corresponding screw-pressing station 4 for screw-pressing assembly. The assembly process is as follows: the first Z-axis drive device 41 moves the mating structure downwards, causing the screw-pressing tube 45 to circumferentially limit the mating joint 23 and engage with the screw 22. When its bottom surface abuts against the pallet 110, the first Z-axis drive device 41 stops operating. The second Z-axis drive device 43 operates, driving the screw-pressing tube 45 downwards via the telescopic shaft 431 to press the pallet 110 further into the paste box 100. During this process, the energized coil 442 is activated. Electricity, combined with the magnetic connection of the magnet, drives the rotation of the screw-pressing tube 45 on the telescopic shaft 431, thereby turning the screw 22. Thus, under the inner spiral guide and the downward pressure of the end face, the tray 110 remains horizontally pressed into the ointment box 100, reducing structural wear, compression, and assembly resistance. During this process, the position of the screw-pressing tube 45 is sensed by the first sensor 432 and the second sensor 46. Once it reaches the first set depth, the screw-pressing device 44 stops operating. Finally, the downward pressure of the second Z-axis drive device 43 presses the tray 110 down a second time and positions it in the ointment box. At the bottom of the body box 100, the screw 22 is guided by the reverse spiral of the support plate 110, causing the positioning spring block 24 to deform laterally and pre-tighten the structure. When it senses that it has reached the second set depth, the second Z-axis drive device 43 stops running, and the two Z-axis drive devices move upward and reset, so that the screw-pressing tube 45 is disengaged from the auxiliary guide 2, thus completing the screw-pressing assembly of a single support plate 110. After all the qualified paste boxes 100 on a single positioning plate 12 have completed the assembly of their support plates 110, the installation depth of the support plates 110 inside the assembled paste box 100 is detected by the post-inspection station 5, and qualified products and defective products are transported separately.

[0061] The post-inspection station 5 is equipped with a third Z-axis drive device 51 and a fourth Z-axis drive device 53. A second slide block 52 is slidably mounted on the third Z-axis drive device 51. The fourth Z-axis drive device 53 is mounted on the second slide block 52, and its output shaft is connected to a connecting frame 54. The connecting frame 54 is an inverted L-shaped structure, with its side slidably fitted onto the surface of the fourth Z-axis drive device 53. Its bottom is connected to a detection guide rod 50, which passes through the second slide block 52. A third sensor 55 for sensing the position of the third Z-axis drive device 51 is also provided on the second slide block 52. During the finished product inspection after assembly, the third Z-axis drive device 51 drives the structure to move downward, causing the detection guide rod 50 to reach the specified height. At this time, the third sensor 55 senses the initial height position, and the fourth Z-axis drive device 53 operates, driving the detection guide rod 50 to move downward and make it abut against the tray 110, and records the final height. The third sensor 55 obtains the descent height and performs a screwing and pressing quality judgment to distinguish between qualified and defective products.

[0062] The workbench 1 is also equipped with a defective product unloading station 6. The defective product unloading station 6 is equipped with an X-axis drive device 61 that drives radially along the movable platform 11 and a fifth Z-axis drive device 62 that docks with the X-axis drive device 61. The fifth Z-axis drive device 62 is equipped with grippers 60 corresponding to the number of paste boxes 100 on a single positioning plate 12. The manual loading station and the automatic unloading station for qualified products are located on both sides of the defective product unloading station 6. After assembly, qualified products are automatically unloaded by the automatic unloading station for qualified products and transferred to the next process. Defective products detected before and after assembly are sorted and collected by the defective product unloading station 6. The X-axis drive device 61 moves the grippers 60 above the defective products, and the fifth Z-axis drive device 62 drives the corresponding grippers 60 to move downward to grip the defective products. Then, the grippers 60 are driven upward and outward to the defective product collection area for unified recycling of defective products. The aforementioned driving device is one or more of a motor, cylinder, or hydraulic cylinder that corresponds to the rotation or extension movement.

[0063] In summary, due to the adoption of the above technical solution, the automatic rotating assembly device for ointment box trays in this embodiment has the following advantages compared with the prior art:

[0064] 1. The assembly device of the present invention, through the auxiliary guide frame and the lifting and rotating driven screw-pressing tube, can realize the inner spiral guidance and outer vertical pressing of the tray during the pressing of the tray into the ointment box, so as to ensure that the tray always slides coaxially with the ointment box and ensures that the tray is assembled in place. In use, by driving the screw-pressing tube to rotate, the screw is driven to rotate, which in turn drives the screw sleeve to provide spiral guidance to the inner side of the tray. Through the downward pressing of the screw-pressing tube and the circumferential limiting of the ointment box on the tray, the tray is stably pressed into the ointment box in a horizontal state. With the cooperation of the front and rear inspection stations, the quality of the ointment box and the tray itself and the installation depth are inspected before and after assembly to ensure high-quality and high-efficiency assembly operation.

[0065] 2. The two-stage pallet screwing and pressing assembly process, which involves pressing down the screwing and pressing tube, driving the screwing in the front process, and pressing down and pressing separately in the back process, ensures that the pallet is guided more fully and the driving resistance is greatly reduced in the front process. In the back process, the elastic pre-tightening effect of the positioning spring ensures the pressing quality. During this process, multiple sensors are used to sense the position of the screwing and pressing tube and the screwing and pressing process to further ensure the assembly quality.

[0066] 3. After assembly, the paste box is tested for tray installation depth using a detection guide rod and sensor to determine its installation quality. Then, qualified and defective products are sorted and collected at the defective product unloading station to improve production efficiency and quality.
