Description

Technical Field

[0001] The utility model relates to the technical field of conveying devices, in particular to arc-shaped and straight-line turning conveying structures. Background Art

[0002] Existing automated production lines are generally divided into two types: linear and circular. A linear production line arranges workstations along a straight line and is suitable for the production of a single process. However, a linear production line is not suitable for multi-station cycle processing because the workpiece needs to move back and forth frequently between different workstations, which is inefficient. In contrast, a circular production line has a circular layout, which can realize multi-station cycle processing and improve production efficiency. In addition, a circular production line can also reduce floor space because the circular layout can make better use of space and reduce the length of the production line.

[0003] The existing annular production line conveying structure is usually composed of a straight part and an arc part, and a mover is used as a loading platform. For example, Chinese patent announcement number CN113783396B discloses "a direct-drive annular flexible conveying system and its coordinated control method", which is directly driven by a primary excitation permanent magnet linear motor, and the higher-cost permanent magnets and armatures are concentrated on one side of the armature as a short mover, while the secondary is only composed of a lower-cost laminated iron core and used as a long stator. The system cost can be greatly reduced, and the asymmetric excitation structure of the permanent magnet can generate a higher amplitude of twice the number of pole pairs of harmonic magnetomotive force under the same amount of permanent magnets. By reasonably selecting the number of secondary teeth, the fundamental magnetomotive force and the second harmonic magnetomotive force can be used evenly, effectively improving the thrust density of the motor;

[0004] However, in actual use, since the mover has a certain inertia during operation, sensors are needed to detect the position of the mover and the items it carries. However, since the annular conveying structure consists of a straight part and an arc part, many sensors need to be installed, and the installation process is cumbersome and time-consuming.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0026] Reference Figure 1-4 , the arc-shaped and straight-line turning conveying structure comprises a support platform 1, and two straight-line conveying structures 2 and two turning conveying structures 3 are arranged on the upper end of the support platform 1;

[0027] The support platform 1 is also provided with a loading platform 4 that cooperates with the linear conveying structure 2 and the turning conveying structure 3. The loading platform 4 cooperates with the linear conveying structure 2 or the turning conveying structure 3 to form a motor structure.

[0028] The support platform 1 is provided with a plurality of first detection components 5 and second detection components 6 respectively cooperating with the straight conveying structure 2 and the turning conveying structure 3;

[0029] The lower end of the stage 4 is provided with a first sensing portion that matches the first detection component 5 , and one side of the stage 4 is provided with a second sensing portion 7 that corresponds to the second detection component 6 .

[0030] In the present invention, the first detection component 5 and the second detection component 6 are used to detect the loading platform 4 passing through the straight conveying structure 2 and the turning conveying structure 3 respectively, so as to avoid the turning conveying structure 3 having an arc, which makes the moving trajectory of the loading platform 4 have an arc and causes inaccurate detection results. During the detection, multiple second detection components 6 are distributed in an arc structure to detect the moving speed of the loading platform 4 on the turning conveying structure 3. In the present invention, the straight conveying structure 2 and the turning conveying structure 3 are stators composed of electromagnetic structures, and the loading platform 4 is a mover with a permanent magnet. The straight conveying structure 2 and the turning conveying structure 3 both use incremental encoders. During assembly, the first detection component 5 and the second detection component 6 can be assembled first, and then installed on the support platform 1 uniformly, which is more convenient.

[0031] Furthermore, in the present embodiment, the straight conveying structure 2 and the turning conveying structure 3 both include a supporting portion 21 and a track 22 fixedly disposed on the supporting portion 21. A plurality of magnetic drive structures 23 are disposed on the supporting portion 21, and the magnetic drive structures 23 cooperate with the loading platform 4 to drive the loading platform 4 to move.

[0032] Furthermore, in this embodiment, the magnetic drive structure 23 includes a mounting portion 231, and a plurality of coils 232 are arranged in the mounting portion 231. The mounting portion 231 and the track 22 of the turning conveying structure 3 are both arc-shaped structures. The arc-shaped track 22 guides the loading platform 4 to perform an arc-shaped motion, thereby preventing the loading platform 4 from deviating from the preset trajectory during operation.

[0033] It should be noted that, in the present embodiment, the first detection component 5 and the second detection component 6 both include a mounting frame 51 and a magnetic grating displacement sensor 52 arranged on the mounting frame 51, a limiting mechanism 8 is arranged on the mounting frame 51, and the lower end of the magnetic grating displacement sensor 52 is provided with a plug-in portion 9 that cooperates with the limiting mechanism 8. The plug-in portion 9 and the magnetic grating displacement sensor 52 are fixed by the limiting mechanism 8, so as to facilitate the assembly of the first detection component 5 and the second detection component 6.

[0034] Furthermore, in the present embodiment, the limiting mechanism 8 includes a slot 81 opened on the mounting frame 51 and corresponding to the plug-in portion 9, and a baffle 82 is provided on one side of the slot 81. The baffle 82 is provided to limit the plug-in portion 9 and the magnetic grating displacement sensor 52, so that the slot 81 and the limiting mechanism 8 can be easily aligned during installation.

[0035] In detail, in the present embodiment, a limit slot 83 is provided on the plug-in portion 9, and a mounting slot is provided on the mounting frame 51. A plug plate 84 matching the limit slot 83 is slidably provided in the mounting slot. An adjusting component matching the plug plate 84 is also provided in the mounting slot. When the magnetic grating displacement sensor 52 is installed, the position of the plug plate 84 is controlled by the adjusting component to prevent obstruction to the installation of the magnetic grating displacement sensor 52. After the magnetic grating displacement sensor 52 is installed in place, the slot 81 corresponds to the position of the plug plate 84, and the plug plate 84 is controlled to be plugged into the slot 81, thereby fixing the magnetic grating displacement sensor 52.

[0036] In more detail, in the present embodiment, the adjustment assembly includes a reset spring 85, a gear 86 and a pressing portion 87. One side of the pressing portion 87 passes through the mounting slot and extends to one side thereof. The pressing portion 87 and the plug plate 84 are fixedly provided with a spur rack meshingly connected to the gear 86. One end of the reset spring 85 abuts against the mounting slot, and the other end abuts against the pressing portion 87 or the plug plate 84. By controlling the movement of the pressing portion 87, under the action of the gear 86, the plug plate 84 moves in the opposite direction and is plugged into or separated from the slot 81, thereby fixing or releasing the magnetic grating displacement sensor 52.

[0037] Working mode: When working, the loading platform 4 passing through the straight conveying structure 2 and the turning conveying structure 3 respectively is detected by the first detection component 5 and the second detection component 6. When assembling, the first detection component 5 and the second detection component 6 can be assembled first, and then installed on the support platform 1 uniformly, which is more convenient. First, the plug-in part 9 of the magnetic grating displacement sensor 52 is inserted into the slot 81, and the pressing part 87 is moved inward to cooperate with the gear 86 to control the plug plate 84 to retract into the installation groove, and the magnetic grating displacement sensor 52 is moved until it abuts against the baffle 82, and the pressing part 87 is released. Under the action of the reset spring 85, the plug plate 84 is plugged into the slot 81 to fix the magnetic grating displacement sensor 52.
