[0035] To keep the following description of the embodiments of this utility model clear and concise, detailed descriptions of known functions and known components are omitted.

[0036] Please refer to Figure 1 2. This utility model document proposes a partitioned negative pressure adsorption system, the specific scheme of which is as follows:

[0037] The carrier 3 is mounted on a carrier mounting base, which is connected to the conveyor rail;

[0038] The upper cover plate 1 is set on the top of the vehicle 3; the upper cover plate 1 is divided into multiple ventilation holes 101; the lower bottom plate 2 is set on the bottom of the vehicle 3 and can be detachably installed with the upper cover plate 1; the vehicle 3 is provided with multiple negative pressure zones, and the multiple negative pressure zones are arranged at intervals; the multiple negative pressure zones are arranged corresponding to the multiple ventilation holes 101.

[0039] The control module includes multiple control switches, which are used to control the opening or closing of multiple negative pressure zones.

[0040] The lower end of the bottom plate 2 is provided with an air intake 29 that is connected to the air intake device.

[0046] Furthermore, a third negative pressure zone 23 is also provided inside the vehicle 3; the third negative pressure zone 23 is arranged adjacent to the second negative pressure zone 22.

[0047] Furthermore, the third negative pressure zone 23 is divided into a fourth zone 231 and a fifth zone 232; the fourth zone 231 and the fifth zone 232 are respectively provided with a fourth air outlet and a fifth air outlet at their adjacent ends; the fourth air outlet and the fifth air outlet are respectively connected to the first negative pressure airway 20.

[0048] Additional information: The vehicle 3 is also equipped with a fourth negative pressure zone 24, which is divided into a sixth section 241 and a seventh section 242. The sixth and seventh sections 241 and 242 are respectively provided with a sixth air outlet and a seventh air outlet at their adjacent ends. The sixth and seventh air outlets are respectively connected to the first negative pressure air passage 20.

[0049] Furthermore, a fifth negative pressure zone 25 is provided inside the vehicle 3; the fifth negative pressure zone 25 is divided into an eighth section 251 and a ninth section 252; an eighth air outlet and a ninth air outlet are respectively provided at the adjacent ends of the eighth section 251 and the ninth section 252; the eighth air outlet and the ninth air outlet are respectively connected to the first negative pressure airway 20.

[0050] Furthermore, a sixth negative pressure zone 26 is also provided inside the vehicle 3; the sixth negative pressure zone 26 is divided into a tenth section 261 and an eleventh section 262; a tenth air outlet and an eleventh air outlet are respectively provided at the adjacent ends of the tenth section 261 and the eleventh section 262; the tenth air outlet and the eleventh air outlet are respectively connected to the first negative pressure airway 20.

[0051] Meanwhile, a seventh negative pressure zone 27 is also provided inside the vehicle 3; the seventh negative pressure zone 27 is divided into a twelfth section 271 and a thirteenth section 272; the twelfth air outlet and the thirteenth air outlet are respectively provided at the adjacent ends of the twelfth section 271 and the thirteenth section 272; the twelfth air outlet and the thirteenth air outlet are respectively connected to the first negative pressure airway 20.

[0052] Finally, the vehicle 3 is also equipped with an eighth negative pressure zone 28; the eighth negative pressure zone 28 is divided into a fourteenth section 281 and a fifteenth section 282; the fourteenth air outlet and the fifteenth air outlet are respectively provided at the adjacent ends of the fourteenth section 281 and the fifteenth section 282; the fourteenth air outlet and the fifteenth air outlet are respectively connected to the first negative pressure airway 20.

[0053] Furthermore, the second and third air outlets are respectively equipped with a second control switch and a third control switch; the second and third control switches are used to open or close the second and third air outlets respectively, so as to connect or disconnect the second partition 221 and the third partition 222 from the first negative pressure airway 20.

[0054] like Figure 3 As shown, an embodiment is provided in which both the second control switch and the third control switch are piezoelectric ceramics 41.

[0055] like Figure 4 As shown, another embodiment is provided, in which both the second control switch and the third control switch are electromagnetic control switches 42.

[0056] In one embodiment, the fifth negative pressure zone 40 is cylindrical and is located inside the carrier 3. It is composed of two semi-cylinders, an upper cover plate 1 and a lower base plate 2.

[0057] It should also be noted that no control switch is installed between the first air outlet and the first negative pressure air passage 20. However, control switches are installed between the negative pressure zones of the gas and the first negative pressure air passage 20, and each negative pressure zone except the first negative pressure zone has two control switches. Each control switch is ultimately controlled by the control module and operates synchronously, thereby realizing the connection or disconnection between each negative pressure zone and the first negative pressure air passage 20.

[0058] In another embodiment, each negative pressure zone except the first negative pressure zone has two control switches. Each control switch is ultimately controlled by the control module and operates asynchronously. Therefore, the control module can control one section of a negative pressure zone independently, thereby enabling the connection or disconnection of a negative pressure zone with the first negative pressure airway 20 independently.

[0059] like Figure 5 As shown, this utility model also provides a segmented conveying multi-carrier cyclic motion control track, including two or more partitioned negative pressure adsorption systems as described above.

[0060] It also includes an upper conveyor rail 7, a lower conveyor rail 8, a front lifting rail, a rear lifting rail, a system control module, and a position sensor mounted on the frame. The upper conveyor rail 7 includes a loading area 10, a precision conveying area 11, a non-precision conveying area 12, and a unloading area 9. The carrier 3 can move sequentially along the front lifting rail, the upper conveyor rail 7, the rear lifting rail, and the lower conveyor rail in a circular motion. The precision conveying area 11 is equipped with a precision drive mechanism, and the non-precision conveying area 12 and the lower conveyor rail are both equipped with non-precision drive mechanisms. Both the precision drive mechanism and the non-precision drive mechanism can be connected to the carrier 3 through a lock body to drive the carrier 3 to move. The position sensor is used to detect the position information of the carrier 3. The system control module controls the lock body to close or lock based on the position information of the carrier 3 to control the precision drive mechanism or the non-precision drive mechanism to drive the carrier 3 to move.

[0061] Two air intakes 29 are located on the left and right sides of the bottom plate 2, and are connected to the first air intake device 5 and the second air intake device 6 respectively during operation.

[0062] The first suction device 5 and the second suction device 6 are connected to the suction pump, respectively. Their suction operation alternates with that of the same carrier 3, enabling the same carrier 3 to move from the precision conveying area 11 to the non-precision conveying area 12. Specifically, when the carrier 3 moves from the loading area 10 to the precision conveying area 11, the first suction device 5 is in a standby state; when moving from the non-precision conveying area 12 to the unloading area 9, the second suction device 6 is in a standby state. The second carrier then repeats the above operation process.

[0063] There are two air pumps, which are installed on both sides of the upper conveying track 7.

[0064] like Figure 6 , Figure 7 As shown, the air intake device is a linear magnetic drive air intake device 13; the linear magnetic drive air intake device 13 includes an air intake channel 131, an air chamber 132, a first compression chamber 133, and a second compression chamber 134.

[0065] The first compression chamber 133 and the second compression chamber 134 are surrounded by energized coils, namely the first energized coil 1333 and the second energized coil 1334, with the two coils wound in the same direction. Inside the first compression chamber 133 and the second compression chamber 134, a first magnet 1331 and a second magnet 1341 are respectively installed to compress and discharge the gas within their respective chambers. The first compression chamber 133 and the second compression chamber 134 are connected to the air chamber 132, with an air inlet 1321 and an air inlet 1322 at each connection point. Simultaneously, an air outlet 1332 and an air outlet 1342 are respectively located at the top of the first compression chamber 133 and the second compression chamber 134 near the air chamber 132.

[0066] It should be noted that the first energized coil 1333 and the second energized coil 1334 are energized in opposite directions. Therefore, when energized, the first magnet 1331 and the second magnet 1341 move in opposite directions under the influence of the magnetic field of the energized coils. When the first magnet 1331 moves downward, since the air pressure in the first compression chamber 133 is lower than that in the air chamber 132 and the outside, the first air inlet 1321 opens and the first air outlet 1332 closes under the action of air pressure. Therefore, the first compression chamber 133 is filled with gas. At the same time, the second magnet 1341 moves upward. Under the action of air pressure, the second air inlet 1322 is closed and the second air outlet 1342 is open, and the gas in the second compression chamber 134 is discharged through the second air outlet 1342.

[0067] Conversely, when the second magnet 1341 moves downward, since the air pressure in the first compression chamber 134 is lower than that in the air chamber 132 and the outside, the second air inlet 1322 is open and the second air outlet 1342 is closed under the action of air pressure. The second compression chamber 134 is filled with gas through the second air inlet 1322. At this time, the first magnet 1331 moves upward, and the first air inlet 1321 closes and the first air outlet 1332 opens under the action of air pressure, and the gas in the first compression chamber 133 is discharged.
