Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. For ease of explanation, the terms "vertical", "horizontal", "left", "right", "upper", "lower", "inner", "outer", "bottom", etc. used in this specification indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.

[0020] Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making any creative work shall fall within the scope of protection of the present invention.

[0021] Embodiment 1

[0022] As attached Figure 1-8 As shown, a powder-liquid double-chamber bag light inspection bag loading device includes a conveying device 1, a primary transport mechanism 2, a bag sorting ring belt mechanism 3, a secondary transport mechanism 4 and a light inspection ring belt mechanism 5.

[0023] As attached Figure 1-2 As shown, the two ends of the powder-liquid double chamber bag 6 are respectively a powder chamber 61 and a liquid chamber 62, with a dividing strip in the middle, a nozzle 64 is provided at the end of the liquid chamber 62, and a circular positioning hole 63 is provided around the edge of the powder chamber 61.

[0024] In the existing production process of the powder-liquid double chamber bag 6, after the powder filling machine fills the powder raw material, the powder-liquid double chamber bag 6 is transported to the next process by the conveying device 1. Specifically, the powder-liquid double chamber bag 6 is continuously transported to the downstream process by the endless belt 11 of the conveying device 1.

[0025] As attached Figure 2-4 As shown, the primary transport mechanism 2 is used to quickly grab the powder-liquid double-chamber bag 6 on the endless belt 11 and put it into the bag sorting endless belt mechanism 3. The primary transport mechanism 2 includes a manipulator 21 and a grabbing platform 22, and a plurality of primary clamping stations 31 are arranged on the bag sorting endless belt mechanism 3. The primary transport mechanism 2 grabs the powder-liquid double-chamber bag 6 from the endless belt 11 and moves it to the top of the primary clamping station 31, then releases the powder-liquid double-chamber bag 6, and the powder-liquid double-chamber bag 6 naturally falls into the primary clamping station 31 under the action of gravity.

[0026] The manipulator 21 uses a spider man manipulator in the prior art, which can identify and obtain the position of the powder-liquid double chamber bag 6 on the endless belt 11 through visual detection technology, and quickly move to the top of the powder-liquid double chamber bag 6. The grabbing platform 22 is a horizontal plate-shaped structure, which is installed below the manipulator 21 so that the manipulator 21 can drive the grabbing platform 22 to move.

[0027] The grabbing platform 22 is provided with one or more first suction cups 221 for sucking the powder-liquid double-chamber bag 6. The first suction cups 221 are connected with a negative pressure pipeline, so that after contacting the powder-liquid double-chamber bag 6, the powder-liquid double-chamber bag 6 is sucked by negative pressure. The position of the first suction cups 221 on the grabbing platform 22 can be adjusted to facilitate the grabbing of powder-liquid double-chamber bag 6 products of different specifications.

[0028] The primary clamping station 31 includes a powder cavity area 311 and a liquid cavity area 312. After the powder-liquid dual-chamber bag 6 is filled with the powder raw materials and the liquid raw materials, the liquid cavity 62 is relatively bulging and the powder cavity 61 is relatively flat, so the height of the powder cavity area 311 is higher than the liquid cavity area 312, so that the powder-liquid dual-chamber bag 6 can maintain a stable horizontal state in the primary clamping station 31, which is convenient for positioning the powder-liquid dual-chamber bag 6.

[0029] The bag sorting ring belt is an annular conveyor belt structure, which can transfer the powder-liquid double-chamber bag 6 located in the primary clamping station 31 to the secondary transport mechanism 4. The bag sorting ring belt mechanism 3 also includes a baffle 32, a primary positioning block 33 and a primary clamping hand 34.

[0030] The baffle 32 is a plate-like structure vertically arranged around the powder chamber area 311. The distribution positions of the multiple baffles 32 are adapted to the outer edge contour of the powder chamber 61, and the outer edge contour area formed by the multiple baffles 32 is slightly larger than the area of ​​the powder chamber 61, thereby preliminarily positioning the powder chamber 61.

[0031] The first-level positioning block 33 is a long strip-shaped block structure, and two first-level positioning blocks 33 are symmetrically arranged on both sides of the liquid chamber area 312. The upper surfaces of the two first-level positioning blocks 33 are inclined surfaces, and the inclined directions are arranged facing each other, so as to guide the liquid chamber 62. The distance between the two first-level positioning blocks 33 is slightly larger than the size of the liquid chamber 62, so as to preliminarily position the liquid chamber 62.

[0032] The first-level gripper 34 is used to grip and position the nozzle 64 of the powder-liquid double-chamber bag 6. The first-level gripper 34 is composed of two first-level clamping columns 341 arranged opposite to each other, and the distance between the two first-level clamping columns 341 is slightly larger than the size of the nozzle 64. The tops of the two first-level clamping columns 341 are provided with guiding inclined surfaces 3411 arranged opposite to each other, and the guiding inclined surfaces 3411 have a guiding effect on the nozzle 64, so as to facilitate the nozzle 64 to enter the first-level gripper 34.

[0033] As attached Figure 5-8 As shown, a plurality of secondary clamping stations 51 are arranged on the light inspection ring belt mechanism 5, and the secondary transport mechanism 4 is used for grabbing the powder-liquid double-chamber bag 6 in the primary clamping station 31 and pressing it into the secondary clamping station 51. The light inspection ring belt is a ring conveyor belt structure, which can transport the powder-liquid double-chamber bag 6 in the secondary clamping station 51 to the light inspection area downstream of the production line.

[0034] The secondary transport mechanism 4 includes a transport frame 41 and a grabbing fixture 42. The transport frame 41 includes a horizontal moving mechanism 411, a vertical moving mechanism 412 and a mounting platform 413.

[0035] The mounting platform 413 is a horizontal plate-like structure, and in this embodiment, four grabbing fixtures 42 are installed side by side below it. The mounting platform 413 is driven by a horizontal moving mechanism 411 and a vertical moving mechanism 412, so that the grabbing fixtures 42 can be driven to move back and forth in the horizontal and vertical directions. In this embodiment, the horizontal moving mechanism 411 is driven by an electric cylinder, and the vertical moving mechanism 412 is driven by an air cylinder. The air cylinder is a cylindrical metal part that guides the piston to perform linear reciprocating motion in the cylinder, and the electric cylinder is a modular product that integrates a servo motor and a lead screw, both of which are mature products in the prior art.

[0036] The grabbing fixture 42 in this embodiment is used to grab and release four powder-liquid dual-chamber bags 6 simultaneously.

[0037] The grabbing fixture 42 comprises a bag pushing pin 422, a second suction cup 421 and a bag taking gripper 423. The second suction cup 421 is communicated with the negative pressure pipeline, and the second suction cup 421 can absorb or release the powder-liquid double chamber bag 6.

[0038] The bag taking gripper 423 is used to clamp or release the pipe mouth 64 of the powder-liquid dual-chamber bag 6. The bag taking gripper 423 includes a stopper 4231 and a clamping block 4232 which are integrally arranged. The stopper 4231 is a horizontally arranged L-shaped structure, and its bottom is a clamping block 4232 with a circular arc surface. The two stoppers 4231 are combined to form a U-shaped stopper structure, and the two clamping blocks 4232 are combined to form an arc-shaped clamping structure. Both stoppers 4231 can rotate around the connection between the two stoppers 4231, driving the clamping block 4232 to rotate synchronously, so that the two clamping blocks 4232 clamp or release the pipe mouth 64 of the powder-liquid dual-chamber bag 6.

[0039] The bag pushing pin 422 is a vertically arranged columnar structure, which can be retracted vertically. When the grabbing fixture 42 grabs the powder-liquid double-chamber bag 6, the bag pushing pin 422 retracts vertically upward; when the grabbing fixture 42 releases the powder-liquid double-chamber bag 6, the bag pushing pin 422 extends vertically downward to abut against the powder-liquid double-chamber bag 6, and the abutting position of the bag pushing pin 422 and the powder-liquid double-chamber bag 6 is close to the positioning hole 63 on the powder-liquid double-chamber bag 6 and does not interfere with the positioning hole 63.

[0040] The secondary clamping station 51 includes a powder cavity inspection area 511 and a liquid cavity fixing area 512. In order to facilitate the subsequent light inspection process to fully and thoroughly inspect each position of the powder cavity 61, the height of the powder cavity inspection area 511 is lower than the liquid cavity fixing area 512, and the surrounding of the powder cavity inspection area 511 is hollowed out to fully expose the powder cavity 61.

[0041] Each secondary clamping station 51 on the light inspection endless belt mechanism 5 is provided with a positioning pin 54 , a secondary positioning block 52 and a secondary clamping hand 53 .

[0042] The secondary positioning block 52 is a long strip block structure, and two secondary positioning blocks 52 are symmetrically arranged on both sides of the liquid chamber fixing area 512. The upper surfaces of the two secondary positioning blocks 52 are inclined surfaces, and the inclined directions are arranged facing each other, so as to guide the liquid chamber 62. The distance between the two secondary positioning blocks 52 is adapted to the size of the liquid chamber 62, so as to accurately position the liquid chamber 62.

[0043] The secondary gripper 53 is used to grip and position the nozzle 64 of the powder-liquid double-chamber bag 6. The secondary gripper 53 is composed of two secondary clamping columns 531 arranged opposite to each other, and the distance between the two secondary clamping columns 531 is adapted to the size of the nozzle 64. The tops of the two secondary clamping columns 531 are provided with spring pins 5311 arranged opposite to each other. When the nozzle 64 enters the secondary gripper 53, the spring pin 5311 is compressed and retracted; when the nozzle 64 enters the secondary gripper 53, the spring pin 5311 automatically pops out, thereby firmly fixing the nozzle 64 in the internal space of the secondary gripper 53, preventing the nozzle 64 from slipping out of the secondary gripper 53 by itself.

[0044] When the secondary transport mechanism 4 presses the powder-liquid dual-chamber bag 6 into the secondary clamping station 51, the two positioning pins 54 at the end of the powder chamber inspection area 511 are respectively aligned with the two positioning holes 63 on the powder-liquid dual-chamber bag 6, and are inserted into the positioning holes 63 to cooperate with the positioning holes 63 to achieve accurate positioning. In addition, the arrangement of the bag pushing pin 422 can ensure that the positioning pin 54 can be fully inserted into the positioning hole 63.

[0045] The implementation principle of the above embodiment is: When the conveying device 1 is in operation, the powder-liquid double-chamber bag 6 is continuously conveyed to the primary transport mechanism 2 along the endless belt 11. The manipulator 21 quickly moves to the top of the powder-liquid double-chamber bag 6 through visual recognition, and then starts to pump air in the negative pressure pipe connected to the first suction cup 221, sucking up the powder-liquid double-chamber bag 6 on the endless belt 11 and driving it to move to the top of a primary clamping station 31 at the bag sorting endless belt mechanism 3. At this time, the negative pressure pipe stops pumping air, the negative pressure disappears, and the current powder-liquid double-chamber bag 6 naturally falls into the primary clamping station 31, and the manipulator 21 returns to the endless belt 11 to repeat the above steps and perform the transport action uninterruptedly.

[0046] The running bag sorting annular belt mechanism 3 transfers the powder-liquid double-chamber bag 6 that has completed preliminary positioning to the secondary transport mechanism 4. The secondary transport mechanism 4 uses the horizontal moving mechanism 411 and the vertical moving mechanism 412 to make the four grabbing clamps 42 align and contact the powder-liquid double-chamber bags 6 in the four primary clamping stations 31 at the same time. The bag taking clamp 423 is opened and tightened, the pipe mouth 64 is clamped, and the negative pressure pipeline connected to the second suction cup 421 begins to evacuate air, and the powder-liquid double-chamber bags 6 in the four primary clamping stations 31 are sucked up and driven to move to the top of the four secondary clamping stations 51 at the light inspection annular belt mechanism 5. At this time, the vertical moving mechanism 412 moves vertically downward, presses the powder-liquid double-chamber bag 6 into the secondary clamping station 51, and the negative pressure pipeline stops evacuating air, the negative pressure disappears, and the current four powder-liquid double-chamber bags 6 are fixed in the secondary clamping station 51, and are transported to the light inspection area downstream of the production line by the light inspection annular belt mechanism 5, realizing the automatic connection of the front and back processes.
