[0047] See also Figure 1-7 The present invention provides a technical solution: an automatic rotating assembly device for a paste box support plate, comprising:

[0048] A workbench 1, on which a movable platform 11 is rotatably provided, and a plurality of positioning plates 12 are equidistantly provided along the circumference of the movable platform 11;

[0049] A plurality of auxiliary guide frames 2 are mounted on the positioning plate 12, and include a base 21 and a screw 22 rotatably arranged 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 on the screw 22, and a butt joint 23 is arranged on the top thereof;

[0051] A plurality of screwing and pressing stations 4 are arranged equidistantly along the circumference of the movable platform 11, on which screwing and pressing tubes 45 and a driving mechanism for driving the screwing and pressing tubes 45 to rise, fall and rotate are arranged.

[0052] The post-inspection station 5 is used to inspect the installation depth of the support plate 110 after assembly.

[0053] The assembly device of the present invention can realize the inner spiral guiding and outer vertical pressing of the pallet during the process of pressing the pallet into the paste box through the screwing and pressing tube driven by the auxiliary guide frame and the lifting and rotating, so as to ensure that the pallet always slides coaxially with the paste box relative to each other, and ensure that the pallet is assembled in place. When in use, the screwing and pressing tube is driven to rotate, thereby driving the screw to rotate, so as to cooperate with the screw sleeve to spirally guide the inner side of the pallet, and through the downward pressing activity of the screwing and pressing tube and the circumferential limitation of the paste box on the pallet, the pallet is stably pressed into the paste box in a horizontal state; cooperate with the front and rear inspection stations to inspect the paste box before and after assembly, the quality of the pallet itself and the installation depth, so as to ensure high-quality and high-efficiency assembly operations.

[0054] In order to improve the accuracy of the detection results of parameters such as the appearance of the paste box 100 before assembly, a fixed platform 13 is provided on the inner side of the movable platform 11, and the front detection station 3 is assembled on the fixed platform 13, on which sensors corresponding to the number of paste boxes 100 on the single positioning plate 12 are provided.

[0055] In one embodiment, the docking joint 23 is tapered as a whole, and positioning spring blocks 24 extend from both sides thereof. The positioning spring blocks 24 are slidably docked with guide grooves arranged vertically on the inner wall of the screw-pressed tube 45 .

[0056] The driving mechanism includes a first Z-axis driving device 41 and a second Z-axis driving device 43. The first Z-axis driving device 41 is slidably provided with a first slide seat 42. The second Z-axis driving device 43 is assembled on the first slide seat 42. The bottom of the telescopic shaft 431 thereof is rotated to connect with the screwing and pressing tube 45.

[0057] The driving mechanism also includes a screwing device 44, which includes a power supply device and a driving seat 441 at the top. A power-carrying coil 442 is arranged in the driving seat 441. The screwing pressing tube 45 is passed through the power-carrying coil 442, and a magnet is arranged in it. The wiring rack 443 at the bottom of the power supply device leads out electric wires, and the electric wires are connected to the power-carrying coil 442.

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

[0059] The first slide seat 42 is provided with a pair of second sensors 46 . The second sensors 46 are provided at the same height and are used to sense the positions of the telescopic shaft 431 and the screw-pressed tube 45 .

[0060] The working principle of the automatic rotating assembly device for a paste box support plate of the present embodiment includes: during the assembly operation, the manual loading station manually performs assembly positioning between the positioning plate 12, the auxiliary guide frame 2, and the paste box 100, and then presses the support plate 110 into the inner cavity of the paste box 100, and the screw sleeve 120 docks with the screw rod 22 to perform preliminary assembly of the support plate 110; the movable platform 11 operates to transfer the components to be assembled to the front inspection station 3, and the sensors thereon perform pre-assembly inspection on the paste box 100 and the support plate 110, and mark the defective products so that they skip the subsequent assembly process and are collected in a centralized manner; the components to be assembled are further inspected and collected. During transportation, several support plates 110 are moved to the bottom of the screwing and pressing tubes 45 of the corresponding screwing and pressing stations 4 in turn for screwing and pressing assembly. The assembly process is specifically as follows: the first Z-axis driving device 41 drives the docking structure to move downward, and makes the screwing and pressing tube 45 circumferentially limit the docking joint 23 and sleeved on the screw 22. When its bottom surface abuts against the support plate 110, the first Z-axis driving device 41 stops running; the second Z-axis driving device 43 runs, and drives the screwing and pressing tube 45 to move downward through the telescopic shaft 431 to press the support plate 110 downward, so that it continues to be pressed into the paste box 100. During this period, the energized coil 442 is turned on The screw 22 is then screwed to rotate, thereby keeping the support plate 110 horizontally pressed in the paste box 100 under the action of the inner spiral guide and the downward pressure of the end surface, so as to reduce structural wear, extrusion and assembly resistance. During this period, the position of the screwed and pressed tube 45 is sensed by the first sensor 432 and the second sensor 46, so that after reaching the first set depth, the screwing device 44 stops running. Finally, the support plate 110 is pressed down for the second time by the downward pressure of the second Z-axis drive device 43 and positioned in the paste box 100. At the bottom of the body box 100, the screw 22 is guided by the reverse spiral of the support plate 110, so that the positioning spring block 24 is laterally elastically deformed to pre-tighten the structure. When it is sensed 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 up and reset, so that the screwing and pressing tube 45 is disengaged from the auxiliary guide frame 2, and the screwing and pressing assembly of the single support plate 110 is completed; when all qualified paste boxes 100 on the single positioning plate 12 have completed the assembly of their upper support plates 110, the installation depth of the inner support plate 110 of the assembled paste box 100 is inspected by the post-inspection station 5, and qualified products and defective products are transported separately.

[0061] The rear inspection station 5 is provided with a third Z-axis driving device 51 and a fourth Z-axis driving device 53. A second slide 52 is slidably provided on the third Z-axis driving device 51. The fourth Z-axis driving device 53 is assembled on the second slide 52, and the output shaft thereof is docked with a connecting frame 54. The connecting frame 54 is an inverted L-shaped structure, and its side surface is slidably assembled with the surface of the fourth Z-axis driving device 53, and its bottom is docked with a detection guide rod 50, and the detection guide rod 50 is penetrated on the second slide 52. The second slide 52 is also provided with a third sensor 55 for sensing the position of the third Z-axis driving device 51. When inspecting the finished product after assembly, the third Z-axis drive device 51 drives the structure downward so that the detection guide rod 50 reaches the specified height. At this time, the third sensor 55 senses the initial height position, and the fourth Z-axis drive device 53 operates to drive the detection guide rod 50 to move downward, and make it contact with the support plate 110, and record the final height. The third sensor 55 obtains the descending height and makes a screwing and pressing quality judgment to distinguish qualified products from defective products.

[0062] The workbench 1 is also provided with a defective product unloading station 6, on which an X-axis driving device 61 driven radially along the movable platform 11 and a fifth Z-axis driving device 62 connected to the X-axis driving device 61 are provided, and the fifth Z-axis driving device 62 is provided with gripping fingers 60 corresponding to the number of paste boxes 100 on a single positioning plate 12. The manual loading station and the qualified product automatic unloading station are arranged on both sides of the defective product unloading station 6. After assembly, the qualified products are automatically unloaded by the qualified product automatic unloading station and transferred to the next process, and the defective products detected before and after assembly are sorted and collected by the defective product unloading station 6. The X-axis driving device 61 moves the gripping fingers 60 to the top of the defective products, and drives the corresponding gripping fingers 60 to move downward through the fifth Z-axis driving device 62 to grip the defective products, and then the gripping fingers 60 are driven to move upward and outward to the defective product collection area to uniformly recycle the defective products. The driving device is one or more of a motor, a cylinder or a hydraulic cylinder corresponding to the rotation or telescopic activity mode.

[0063] In summary, due to the adoption of the above technical solution, the paste box support plate automatic rotation assembly device of this embodiment has the following beneficial effects compared with the prior art:

[0064] 1. The assembly device of the present invention can realize the inner spiral guiding and outer vertical pressing of the pallet during the process of pressing the pallet into the paste box through the screwing and pressing tube driven by the lifting and rotating auxiliary guide frame, so as to ensure that the pallet always slides coaxially with the paste box and ensures that the pallet is assembled in place. When in use, the screwing and pressing tube is driven to rotate, thereby driving the screw to rotate, so as to cooperate with the screw sleeve to spirally guide the inner side of the pallet, and through the downward pressing activity of the screwing and pressing tube and the circumferential limitation of the paste box on the pallet, the pallet is stably pressed into the paste box in a horizontal state; cooperate with the front and rear inspection stations to inspect the paste box before and after assembly, the quality of the pallet itself and the installation depth to ensure high-quality and high-efficiency assembly operations.

[0065] 2. The two-stage support plate twisting and pressing assembly process includes the front process of pressing down the twisting and pressing tube, the front process of twisting and driving, and the back process of pressing down for secondary pressing separately. This makes the support plate more fully guided in the front process and greatly reduces the driving resistance. In the back process, the elastic pre-tightening effect of the positioning spring piece is used to ensure the pressing quality. During this period, the position of the twisting and pressing tube and the twisting and pressing process are sensed by multiple sensors to further ensure the assembly quality.

[0066] 3. After assembly, the paste box is tested for the depth of the pallet installation by means of a detection guide rod and a sensor to determine the installation quality. Qualified and defective products are sorted and collected through the defective product unloading station to improve production efficiency and quality.
