Abstract
Description
Technical Field
[0001] This utility model relates to the field of material handling and inspection, specifically to a multi-axis synchronous rotating elastic vacuum suction mechanism. Background Technology
[0002] In existing technologies, material rotation mechanisms mostly employ single or multiple mechanism rotations, with structures primarily consisting of rocker arm rotation and gear rotation. Rocker arm rotation suffers from limited rotation angles, making it unsuitable for large-angle rotations; gear rotation, on the other hand, suffers from backlash and poor repeatability. Utility Model Content
[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a multi-axis synchronous rotating elastic vacuum suction mechanism that achieves elastic pressure adsorption from above and below, avoiding positional displacement caused by suspended suction of items; when installed on the equipment handling module, it can reduce the number of times items are handled and improve equipment operation; it can be used in the inspection station to achieve one-stop multi-position inspection and improve equipment operation.
[0004] The objective of this invention is achieved through the following technical solution: This multi-axis synchronous rotating elastic vacuum suction mechanism includes:
[0005] The flexible vacuum shaft has a pipe connector installed at one end for connecting to external vacuum equipment, and a suction cup integrated at the other end for adsorbing products. A vent hole is opened through the center of the flexible vacuum shaft and the suction cup so that the pipe connector is connected to the vent hole.
[0006] A rotating spindle is sleeved on the outer circumference of an elastic vacuum shaft. A synchronous pulley is mounted on the outer circumference of the rotating spindle, and a flange is provided at the end of the rotating spindle near the suction cup; and
[0007] A spring is fitted onto an elastic vacuum shaft, and the spring rests between the flange and the suction cup;
[0008] The elastic vacuum shaft and the rotating main shaft slide relative to each other along the axial direction while being fixed relative to each other in the circumferential direction, so that the synchronous belt pulley drives the rotating main shaft and the elastic vacuum shaft to rotate synchronously.
[0009] As a further technical solution, an upper mounting plate and a lower mounting plate are also included, which are fixedly connected. The upper mounting plate is supported on the outer ring of the rotating spindle by an upper bearing, and the lower mounting plate is supported on the outer ring of the rotating spindle by a lower bearing. The upper mounting plate and the lower mounting plate are locked onto the flange by a locking nut sleeved on the outside of the rotating spindle.
[0010] As a further technical solution, the locking nut is pressed onto the upper bearing, and the upper bearing and the lower bearing are supported by washers, with the lower bearing pressed onto the flange.
[0011] As a further technical solution, slots are cut into both the upper and lower mounting plates, so that the upper bearing is embedded in the upper mounting plate and the lower bearing is embedded in the lower mounting plate.
[0012] As a further technical solution, the rotating spindle and the synchronous pulley are tightened by a shrinking sleeve.
[0013] As a further technical solution, a step is provided in the middle of the rotating spindle, and the lower part of the timing pulley rests on the step.
[0014] As a further technical solution, a non-circular hole matching the outer contour of the elastic vacuum shaft is opened at the center of the rotating spindle.
[0015] As a further technical solution, a retaining ring groove is opened on the outer wall of the end of the elastic vacuum shaft facing the pipe joint for installing a retaining ring. The retaining ring is used to abut against the upper end face of the rotating spindle, thereby limiting the downward stroke of the elastic vacuum shaft.
[0016] The beneficial effects of this utility model are as follows:
[0017] 1. The rotating spindle is driven by a synchronous belt pulley, and the rotating spindle drives the elastic vacuum shaft through a groove. The elastic vacuum shaft has ventilation holes to achieve the rotation of the adsorbed product.
[0018] 2. The structure is compact and simple, with low cost and high productivity. This method reduces the number of times items need to be handled and allows for the transport of multiple rows and columns of items at once. It effectively improves the efficiency of item handling and rotating transport; without increasing equipment costs, it reduces the cost-to-transport (C / T) ratio of equipment and improves equipment efficiency.
[0019] 3. It can also be used in testing equipment to achieve one-stop multi-position testing, reduce the number of testing stations, reduce equipment size, reduce costs, and improve market competitiveness;
[0020] 4. This structure can be installed on handling equipment and can be promoted for similar items to be rotated and adsorbed for handling and for multi-position detection of items. Attached Figure Description

[0028] The present invention will now be described in detail with reference to the accompanying drawings:
[0029] Example: As attached Figures 1-6 As shown, this multi-axis synchronous rotating elastic vacuum suction mechanism includes a pipe joint 1, a retaining ring 2, a spring 3, an upper bearing 4, a locking nut 5, a synchronous pulley 6, a lower mounting plate 7, an upper mounting plate 8, a washer 9, a rotating spindle 10, an elastic vacuum shaft 11, a shrink sleeve 12, a vent hole 13, a suction cup 14, a retaining ring groove 15, a shaped hole 16, a flange 17, and a lower bearing 18.
[0030] Reference Appendix Figure 1 , 2 A pipe connector 1 is installed at the upper end of the elastic vacuum shaft 11, and a suction cup 14 is integrally set at the lower end of the elastic vacuum shaft 11. At the same time, a vent hole 13 is opened through the center of the elastic vacuum shaft 11 and the suction cup 14. The pipe connector 1 is connected to the top of the vent hole 13, and the suction cup 14 is located at the bottom of the vent hole 13. After the pipe connector 1 is connected to a vacuum pump, the product can be adsorbed by the suction cup 14.
[0031] like Figure 4 , 5 As shown, a shaped hole 16 is formed at the center of the rotating spindle 10. This shaped hole 16 matches the outer contour of the elastic vacuum shaft 11, and both are regular octagons (in this embodiment, they are regular octagons, but other shapes that facilitate torque transmission are also possible). The rotating spindle 10 is sleeved on the outer periphery of the elastic vacuum shaft 11, and a timing pulley 6 is installed on the outer periphery of the rotating spindle 10. Preferably, as shown... Figure 2 As shown, the rotating spindle 10 and the synchronous pulley 6 are tightened together by the expansion sleeve 12. Due to the presence of the irregular hole 16, the elastic vacuum shaft 11 and the rotating spindle 10 remain relatively fixed in the circumferential direction, i.e., they do not rotate relative to each other, allowing the synchronous pulley 6 to drive the rotating spindle 10 and the elastic vacuum shaft 11 to rotate synchronously. Simultaneously, the elastic vacuum shaft 11 can also slide along the axial direction of the rotating spindle 10. Furthermore, as... Figure 2 As shown, spring 3 is sleeved on the elastic vacuum shaft 11, and spring 3 also rests between flange 17 and suction cup 14. When suction cup 14 contacts the product, it can float upward (slide a certain distance along the irregular hole 16 of rotating spindle 10). After suction cup 14 detaches from the product, elastic vacuum shaft 11 returns to its original position relative to rotating spindle 10 under the action of spring 3. Furthermore, as... Figure 2 , 5 As shown in Figure 6, a retaining ring groove 15 is provided on the outer wall of the end of the elastic vacuum shaft 11 facing the pipe joint 1. A retaining ring 2 is installed in the retaining ring groove 15. The retaining ring 2 can be locked against the upper end face of the rotating spindle 10, thereby limiting the downward movement of the elastic vacuum shaft 11 (to prevent the spring 3 from over-resetting).
[0032] Preferably, a step is provided in the middle of the rotating spindle 10, and the lower part of the timing pulley 6 abuts against the step to achieve positioning; the end of the rotating spindle 10 near the suction cup 14 (in the circumferential direction) extends outward to form a flange 17.
[0033] Reference Appendix Figure 2 , 3 The upper mounting plate 8 and the lower mounting plate 7 are fixedly connected by bolts. Both the upper mounting plate 8 and the lower mounting plate 7 have slots, allowing the upper bearing 4 to be embedded in the upper mounting plate 8 and the lower bearing 18 to be embedded in the lower mounting plate 7. That is, the upper mounting plate 8 is supported on the outer ring of the rotating spindle 10 by the upper bearing 4, and the lower mounting plate 7 is supported on the outer ring of the rotating spindle 10 by the lower bearing 18. A locking nut 5, sleeved on the outside of the rotating spindle 10, locks the upper mounting plate 8 and the lower mounting plate 7 onto the flange 17 of the rotating spindle 10. This causes the locking nut 5 to press against the upper bearing 4, and the upper bearing 4 and the lower bearing 18 are supported by a washer 9, with the lower bearing 18 pressed firmly against the flange 17.
[0034] The working process of this utility model:
[0035] During assembly, the rotating spindle 10 uses the irregular hole 16 to cooperate with the elastic vacuum shaft 11. The two (elastic vacuum shaft 11 and rotating spindle 10) can transmit torque, and the elastic vacuum shaft 11 can also slide along the axial direction of the rotating spindle 10. The rotating spindle 10 is tightened and fixed by the upper bearing 4, washer 9, lower bearing 18 and locking nut 5; the synchronous pulley 6 is tightened on the rotating spindle 10 by the expansion sleeve 12.
[0036] During operation, negative pressure gas, through the vent 13 of the pipe connector 1 and the flexible vacuum shaft 11, adsorbs the object (product) to be rotated onto the shaft end (suction cup 14) of the flexible vacuum shaft 11, thus achieving adsorption. The flexible vacuum shaft 11 can slide up and down in the irregular hole 16 of the rotating main shaft 10, and its relative position to the rotating main shaft 10 remains consistent. This ensures that the suction cup 14 presses the product downwards during adsorption, achieving elastic up-and-down adsorption and preventing the object from being suspended and causing positional displacement during adsorption. The rotating main shaft 10 and the flexible vacuum shaft 11 are driven to rotate synchronously by the synchronous pulley 6, thus achieving the rotation of the adsorbed product.
[0037] It is understood that, for those skilled in the art, any equivalent substitutions or modifications to the technical solutions and inventive concepts of this utility model should fall within the protection scope of the appended claims.
