Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of conveying equipment, in particular to a ring-shaped assembly table. BACKGROUND

[0002] At present, flow assembly lines are widely used in various production workshops. Due to site or process requirements, the tooling table (tray) used for assembly needs to be recycled, and the tooling table can be independently controlled to stop or flow at each station, and the flow line and other stations remain unaffected. Common circulating flow lines include double-layer flow lines and ring-shaped flow lines. The double-layer flow line needs to be provided with lifting equipment at both ends of the line body for circulating the tooling tables on the upper and lower layers, and the effective stations can only be arranged on the upper layer. If the assembly line is ring-shaped, the line body can be single-layer, but a turntable or other special equipment needs to be provided for the tooling table to turn and circulate, and such a ring-shaped line occupies a large area. The above conventional schemes are complex in equipment, high in manufacturing cost, and low in use efficiency, and because the operating stations on the line are far apart, multiple sets of process auxiliary equipment need to be configured. The present application has the advantages of compact structure, small area occupied, high circulating efficiency, shared auxiliary process equipment, cost saving, and more prominent advantages in scenarios with fewer stations.

[0046] The annular assembly table runs, the drive motor 201 of the drive assembly 2 runs all the time, the drive shaft 206 is driven by the speed reducer 202 all the time, the assembly table 4 is connected with the drive shaft 206 through the connecting assembly 3 and the torsion limiter 205, when the blocking wheel 5031 of the blocking cylinder 503 of the face assembly 5 is lowered, the assembly table 4 moves around the axis of the drive shaft 206, when the blocking wheel 5031 of the blocking cylinder 503 of the face assembly is raised, the assembly table 4 moves to the position where the blocking block 406 contacts with the blocking wheel 5031 of the blocking cylinder 503, the corresponding torsion limiter 205 of the assembly table 4 is overloaded and slips, the drive shaft 206 continues to rotate, and the assembly table 4 does not move, wherein the initial position of the blocking cylinder 503 is the raised state, the sensor 504 is triggered, at this time the drive shaft 206 rotates all the time, the assembly table 4 is blocked by the blocking wheel 5031 of the blocking cylinder 503, which causes the torsion limiter 205 connected therewith to be overloaded and slip, so the assembly table 4 does not move and stops at the original position; when the assembly content of the first station is completed, the operator confirms that the current station condition meets the release condition, presses the release button 506 of the first station, and there is no assembly table 4 in the front second station and the blocking wheel 5031 of the second station blocking cylinder 503 is in the raised state, the control system controls the blocking wheel 5031 of the first station blocking cylinder 503 to be lowered, and the assembly table 4 runs forward, before the assembly table 4 completely leaves the first station, the sensor 504 of the first station is triggered all the time, the blocking wheel 5031 of the first station blocking cylinder 503 does not rise, when the assembly table 4 completely leaves the first station, the sensor 504 of the first station will not be triggered, the signal is lost, at this time the blocking wheel 5031 of the first station blocking cylinder 503 rises, and waits for the next assembly table 4 to enter the station to start the next cycle, pressing the emergency stop button 505 of any station will immediately stop the drive motor 201 to ensure the safety of people and equipment. Thus the control of the flow of each assembly table 4 is realized without affecting the power transmission to other assembly tables 4.

[0047] If the assembly table 4 needs to be removed as a whole, the rotating plunger 409 is pulled out to make the movable head 4091 of the rotating plunger separate from the U-shaped groove 4031 of the rotating block 403, at this time the rotating block can be rotated out of the longitudinal limitation of the first guide rail 501 and the second guide rail 502 with the second cam bearing follower 402, as shown in the position; Figure 6 Then the cover plate 304 of the connecting assembly 3 is removed, at this time the assembly table 4 can be taken out vertically upward as a whole, which is convenient for the maintenance and replacement of the assembly table 4.

4. A ring-shaped assembly table according to claim 1, characterized in that, Two rotating blocks (403) are symmetrically arranged on the base plate (408). Two horizontally arranged second cam bearing followers (402) are installed at both ends of the rotating blocks (403). The axial direction of the second cam bearing followers (402) is perpendicular to the horizontal plane of the base plate (408).

5. A ring-shaped assembly table according to claim 1, characterized in that, The first guide rail (501) and the second guide rail (502) are both annular guide rails. The first guide rail (501) and the second guide rail (502) have different diameters and are concentric circles.

6. A ring-shaped assembly table according to claim 1, characterized in that, Multiple blocking cylinders (503) are evenly distributed in a circular pattern on the support base (1), and multiple sensors (504) are evenly distributed in a circular pattern on the support base (1). The position and number of the sensors (504) match those of the blocking cylinders (503).

7. A ring-shaped assembly table according to claim 1, characterized in that, The first guide rail (501) is connected to a first cam bearing follower (401) installed on the outside of the base plate (408) and a second cam bearing follower (402) installed on one end of the rotating block (403). The second guide rail (502) is connected to a first cam bearing follower (401) installed on the inside of the base plate (408) and a second cam bearing follower (402) installed on the other end of the rotating block (403). The first cam bearing follower (401) is located at the top of the first guide rail (501) and the second guide rail (502), and the second cam bearing follower (402) is located on the side wall of the first guide rail (501) and the second guide rail (502).
