The number of the linear rails 13 is equal to the number of the conveying assemblies 1, and the length of each linear rail 13 in the first direction X is equal to the length of each conveying assembly 1 in the first direction X. Preferably, the plurality of tracks 13 of the plurality of conveyor assemblies 1 are aligned, so that the transmission assembly 2 can move on each conveyor assembly 1, and the transmission assembly 2 can move the carrier 5 from one station to another station.

The spacing adjustment conveying device can further comprise a plurality of vacuumizing assemblies 4, and the vacuumizing assemblies are used for respectively vacuumizing the adsorption holes 52 of the carriers 5 when the carriers 5 stop moving, so that products are adsorbed on the carriers 5 in a vacuum adsorption mode, and the products can be prevented from moving relative to the carriers 5 in the moving process of the carriers 5.

Specifically, as shown in fig. 7 and 10, the carrier 5 may include a fixing block 53, a mounting block 54, a plug 56, and a first elastic member 57. The fixing block 53 is provided with a plurality of suction holes 52 on the side away from the transmission component 2. The fixed block 53 is provided with an air suction passage communicated with the suction hole 52. The mounting block 54 is fixedly disposed on a surface of the fixing block 53 facing the transmission assembly 2, that is, the upper surface of the fixing block 53 is provided with the suction hole 52, and the lower surface of the fixing block 53 is fixedly provided with the mounting block 54. And one surface of the mounting block 54, which is far away from the fixing block 53, is provided with an air suction hole 55. The suction hole 55 can communicate with the suction passage. The plug 56 is slidably mounted in the mounting block 54. More specifically, the plug 56 is slidably mounted in the mounting block 54 along the third direction Z. The first elastic member 57 is disposed between the plug 56 and the fixing block 53, so that the plug 56 blocks the pumping hole 55 to separate the pumping hole 55 from the pumping passage. The first elastic member 57 may be a spring or other elastic member.

As shown in fig. 8 and 10, the pumping channel may specifically include a first channel 591, a second channel 592, and a third channel 593. A first passage 591 and a second passage 592 are provided to the fixing block 53, and a third passage 593 is provided to the mounting block 54. The first passage 591 communicates with the plurality of adsorption holes 52, the second passage 592 communicates with the first passage 591, and the third passage 593 communicates with the second passage 592. When the plug 56 leaves the suction hole 55 (i.e., the plug 56 does not plug the suction hole 55), the suction hole 55 communicates with the adsorption hole 52 through the third passage 593, the second passage 592, the first passage 591; when the plug 56 blocks the air suction hole 55, the air suction hole 55 is isolated from the third channel 593, and the air suction hole 55 is not communicated with the adsorption hole 52.

In this embodiment, the evacuation assembly 4 may include a top block 41, an evacuation block 42, and a third motive member 43. The top block 41 is used for blocking the air pumping hole 55 and preventing air leakage in the process of vacuumizing. The vacuum block 42 is fixedly connected to the top block 41. The vacuum block 42 is provided with a connection 421 for connecting a vacuum power member (not shown). The connection portion 421 may be a connection hole to which a vacuum power member is connected through a pipe. The vacuum pumping power part is used for pumping vacuum to the air pumping hole 55, so that negative pressure is formed on the upper surface of the fixing block 53. The vacuum pumping power part can be a vacuum pumping pump or other power parts, and the application is not limited to this.

The third power member 43 may be mounted to the vacuum block 42. The third power member 43 is used for pushing open the plug 56 and moving the plug 56 away from the suction hole 55. After the plug 56 is pushed open by the third power member 43, the air extracting hole 55 is communicated with the air extracting passage and the vacuum-pumping power member. Specifically, the third power member 43 may be provided with a rod body capable of moving in the third direction Z, and the top block 41 is provided with a hole body for passing the rod body. After the top block 41 blocks the air exhaust hole 55, the third power member 43 can make the rod body move upward to push the plug 56 open, so that the air exhaust hole 55 is communicated with the air exhaust channel, and therefore the vacuum pumping power member can vacuumize the air exhaust hole 55 through the vacuum pumping block 42, that is, vacuumize the air exhaust channel communicated with the air exhaust hole 55 and the adsorption hole 52 communicated with the air exhaust channel.

In order to make the structure more simple and compact and further reduce the space occupied by the pitch adjustment conveyor, a vacuum assembly 4 may be integrated on the positioning assembly 3, as shown in fig. 5. The positioning assembly 3 may include a mounting plate 33 and a second elastic member 34. The vacuum assembly 4 is slidably mounted to the mounting plate 33, for example, the vacuum block 42 may be slidably mounted to the mounting plate 33 by a wire-track slider structure. The second elastic member 34 is abutted between the mounting plate 33 and the vacuum-pumping assembly 4, so that the top block 41 and the mounting block 54 are elastically abutted. The movable end of the second power member 32 is fixedly connected to the mounting plate 33, and the second power member 32 can drive the mounting plate 33 to move the vacuum pumping assembly 4 to approach or move away from the mounting block 54.

After the product is placed on the upper surface of the fixed block 53, the top block 41 shown in fig. 5 moves upward under the action of the second power member 32, the top block 41 blocks the air suction hole 55, and the third power member 43 controls the rod body to push the plug 56 open, so that a gap is formed between the plug 56 and the upper surface of the air suction hole 55, and the suction hole 52 can be vacuumized.

When the carrier 5 needs to move, the third power member 43 drives the rod body to move downward, so that the plug 56 blocks the air extraction hole 55 under the action of the first elastic member 57, thereby keeping the air extraction passages such as the first passage 591 in a negative pressure state, and the second power member 32 drives the top block 41 and the positioning member 31 to move downward, so as to release the positioning of the positioning member 31 and the positioning block 51, and separate the top block 41 from the carrier 5.

In the embodiment, the positioning component 3 and the vacuumizing component 4 are integrated together, so that when the carrier 5 drives the product to move to a corresponding station, the positioning component 3 can position the carrier 5 and vacuumize the carrier 5. The number of the positioning assemblies 3 in this embodiment is not limited, and may be set according to specific working conditions.

Further, a plurality of suction cups 58 may be disposed on a surface (i.e., an upper surface) of the fixing block 53 facing away from the driving assembly 2 for sucking the product. Another vacuum circuit may be used with the plurality of suction cups 58.
