Here, the site load-bearing column is the original support column 303 arranged in the site, and the position of the support column is fixed, so that the arrangement of the sub-transmission line 300 is adjusted according to the actual arrangement position of the site load-bearing column. For example, as shown in the figure, the field bearing columns are arranged in a straight line and are arranged at intervals, and the sub-transmission lines 300 arranged on the field bearing columns are also arranged in a straight line, so that the occupied space of the field bearing columns is fully utilized, and the occupied area of the automatic transmission lines is reduced.

Referring to fig. 1, in one embodiment, the sub-transmission lines 300 are disposed in parallel along a horizontal direction. It can be understood that the sub-conveying lines 300 are in the same horizontal direction, so that the material can be conveyed in the same horizontal plane.

Illustratively, as shown in fig. 1, the sub-transmission line 300 is a straight transmission line. The two straight-line-shaped transmission lines are arranged on two opposite sides of each supporting column 303 respectively, the two straight-line-shaped transmission lines are arranged in parallel, the material taking device 200 is located at the material taking station 301 of each straight-line-shaped transmission line, and after the material taking action is completed, the material taking device moves to the corresponding material placing station 302.

The fixing frame 201 plays a role in fixing and supporting, and provides a similar supporting platform for other components, and the fixing frame 201 is connected to the sub-transmission line 300 in a sliding manner, and meanwhile, other components also move together with the fixing frame 201. The first driving mechanism 202 provides a driving force required when the material taking assembly 203 moves up and down, and the first driving mechanism 202 is disposed on the fixing frame 201, where the first driving mechanism 202 may be a stepping motor. Get material subassembly 203 and be connected with the output of first actuating mechanism 202, get material subassembly 203 and can take place to slide relative to mount 201 promptly, for example, get material subassembly 203 and can slide relative to mount 201 in the vertical direction of gravity, or, slide relative to mount 201 in the direction that is the contained angle with the vertical direction of gravity. The second driving mechanism 205 is used to provide a driving force for the fixing frame 201 to slide on the sub-transmission line 300, and similarly, the second driving mechanism 205 may be a stepping motor. The guide mechanism 204 is used for guiding and limiting the relative sliding of the material taking assembly 203 relative to the fixing frame 201, so that the material taking assembly 203 is prevented from deviating or shaking in the sliding process, the material taking stability and the material taking precision of the material taking assembly 203 are improved, and the material taking time is shortened.

The guide mechanism 204 includes a first guide rail 208 disposed on the first mounting end surface 206 and a slider 209 disposed on the second mounting end surface 207. Thus, the take-out assembly 203 slides relative to the fixed frame 201 in a predetermined guide direction with the first guide rail 208 and the slider 209 fitted. Here, the number of the first guide rails 208 and the sliders 209 is not limited, so as to enable the material taking assembly 203 to slide relative to the fixed frame 201. Optionally, two first guide rails 208 are provided on the first mounting end surface 206, and at least two sliders 209 are provided on each first guide rail 208.

Of course, the positions of the first guide rail 208 and the slider 209 may be reversed according to practical requirements. That is, the guide mechanism 204 includes a slider 209 provided on the first mounting end surface 206 and a first guide rail 208 provided on the second mounting end surface 207.

It can be understood that the more the first installation surface for setting up guide mechanism 204 on the material taking component 203, and the more the second installation surface for setting up guide mechanism 204 on the mount 201, then, the higher the stability and the precision of taking the material component 203 to slide relative to the mount 201, simultaneously, still can improve bearing weight, can be applicable to taking overweight material promptly.

For example, the first mounting surfaces 206 of the take-off assembly 203 can be positioned adjacent to each other, or the first mounting surfaces 206 can be positioned opposite each other. And, when having a plurality of first installation terminal surfaces 206, the mount 201 is then enclosed and establishes the circumference outside at the material taking subassembly 203, satisfies corresponding demand, for example, the mount 201 is tubular structure, has the open end that supplies the material taking subassembly 203 to wear to establish and set up relatively. Thus, each inner wall end surface of the tubular structure is a second mounting end surface 207.

Specifically, referring to fig. 2, the section of the material taking assembly 203 along the direction perpendicular to the sliding direction is square, the fixing frame 201 includes a first fixing plate 210 and a second fixing plate 211 disposed on the first fixing plate 210, and the first fixing plate 210 and the second fixing plate 211 surround the circumferential outer side of the material taking assembly 203. It will be appreciated that the reclaiming assembly 203, which is square in cross-section, has four peripheral side end surfaces, which may each be a first mounting end surface 206, and similarly, the first and

second retaining plates

210 and 211 each have a second mounting end surface 207 facing the first mounting end surface 206. Thus, the first guide rail 208 or the slider 209 of the guide mechanism 204 is mounted on the corresponding first and second mounting

end surfaces

206 and 207.

Referring to fig. 3 and 4, in an embodiment, two opposite sidewalls of the first guide rail 208 are recessed inward to form a guide groove 212, the slider 209 has an accommodating groove 213 for accommodating the first guide rail 208, and two opposite sidewalls of the accommodating groove 213 are outwardly and convexly provided with a protruding rib 214 adapted to the guide groove 212. It will be appreciated that to prevent the slide 209 from being removed from the first guide track 208 in a direction perpendicular to the direction of sliding movement of the take-off assembly 203, guide slots 212 are formed in opposite side walls of the first guide track 208 adjacent to the side wall of the first guide track 208 that connects the take-off assembly 203. Meanwhile, when being installed, the first guide rail 208 is inserted into the receiving groove 213 of the sliding block 209 along the sliding direction of the material taking assembly 203. Meanwhile, the ribs 214 on the two opposite side walls of the receiving groove 213 are inserted into the corresponding guide grooves 212, so that a double anti-slip arrangement is formed between the first guide rail 208 and the slider 209.

Referring to fig. 3 to 6, in an embodiment, the material taking assembly 203 includes a material taking rod 215, a rack 216 engaged with the first driving mechanism 202, and the grabbing mechanism 100 disposed at one end of the material taking rod, the material taking rod 215 has a first mounting end surface 206, the first mounting end surface 206 has a rack 216, and an output end of the first driving mechanism 202 has a gear engaged with the rack 216. It can be understood that the material taking rod 31 is disposed through the fixing frame 201, the first mounting surface 206 is disposed on the material taking rod 31, the number of the racks 216 can be adjusted according to the number of the first driving mechanisms 202, one rack 216 or several racks 216 can be disposed on the first mounting surface 206, and each rack 216 corresponds to one first driving mechanism 202.

Referring to fig. 7 to 10, in one embodiment, the grabbing mechanism 100 includes a fixing portion 10, a driving portion 20, a pushing portion 30, and at least two grabbing portions 40 slidably connected to the fixing portion 10. Here, the fixing portion 10 plays a role of supporting and fixing, the driving portion 20 provides a power source, the pushing portion 30 realizes output or transmission of power, and the grabbing portion 40 plays a role of grabbing an object, and when the pushing portion 30 outputs or transmits a driving force, each grabbing portion 40 is driven to slide relative to the fixing portion 10, so as to achieve the purpose of picking and placing the object.

The pushing portion 30 and the fixing portion 10 are arranged in a relatively sliding manner, the driving portion 20 can drive the pushing portion 30 to slide relative to the fixing portion 10, and the relative position of the pushing portion 30 and the fixing portion 10 can be limited. Here, when the driving part 20 supplies power, the pushing part 30 slides relative to the fixed part 10, and the pushing part 30 acts in contact with each grabbing part 40, so that each grabbing part 40 simultaneously gathers or simultaneously separates to slide, and the action of grabbing or releasing the target object is formed; when the driving part 20 stops outputting power, the pushing part 30 is kept still relative to the fixing part 10, similarly, each grabbing part 40 is in a static state relative to the fixing part 10, at this time, each grabbing part 40 keeps the current grabbing state, and thus, the target object is not easy to fall off from the grabbing parts 40.

Illustratively, the fixed portion 10 has a housing chamber 10a therein, the pushing portion 30 includes a sliding plate 31 slidably connected to the housing chamber 10a and a pushing rod 32 disposed on the sliding plate 31, the sliding plate 31 is adapted to the driving portion 20, and one end of the pushing rod 32 away from the sliding plate 31 abuts against each of the grabbing portions 40. It can be understood that the sliding path of the sliding plate 31 is limited in the accommodation chamber 10a, that is, the sliding plate 31 is limited and guided by the inner wall of the accommodation chamber 10a, so that the sliding plate 31 slides along the axial direction of the fixing part 10. Meanwhile, the pushing rod 32 slides in the accommodating cavity 10a along with the sliding plate 31, and one end of the pushing rod 32 away from the sliding plate 31 abuts against each grabbing part 40, so as to drive each grabbing part 40 to slide towards or away from the central axis of the fixing part 10.

Specifically, the push lever 32 has a first abutment slope 30a, and the catching portion 40 has a second abutment slope 40a fitted to the first abutment slope 30 a. As can be understood, when the push lever 32 slides with the slide plate 31, the first abutment slope 30a and the second abutment slope 40a abut against each other, that is, the second abutment slope 40a slides on the first abutment slope 30a, thereby changing the driving force direction of the driving part 20. And, in order to realize that the grabbing part 40 has a gathering or separating taking and placing state under the driving of the pushing rod 30. The first abutting inclined surface 30a is provided with a guide rib structure 61, and the second abutting inclined surface 40a is provided with a guide groove structure 62 adapted to the guide rib structure 61. With the guide rib structure 61 being received in the guide groove structure 62, an interconnecting force is formed between the first abutting inclined surface 30a and the second abutting inclined surface 40a, so that the first abutting inclined surface 30a and the second abutting inclined surface 40a do not separate regardless of the movement of the push lever 30 toward or away from the catching portion 40. Of course, the positions of the guide rib structures 61 and the guide groove structures 62 may be reversed, that is, the guide groove structures 62 are formed on the first abutting inclined surface 30a, and the guide rib structures 61 are formed on the second abutting inclined surface 40 a.

When the first abutting inclined surface 30a and the second abutting inclined surface 40a abut and slide, the grasping portions 40 are in a pick-and-place state of being gathered or separated. It will be understood that when the number of the catching portions 40 is two, the push rod 32 has two first abutting inclined surfaces 30a adapted to abut against a corresponding number of second abutting inclined surfaces 40 a. When the number of the catching portions 40 is more than three, the pushing rod 32 has more than three annular first abutting inclined surfaces 30a for abutting fit with the second abutting surfaces 40 a.

And the driving part 20 is an input end 20a and an output end 20b communicated with the accommodating cavity 10a, and the input end 20a and the output end 20b are used for external fluid to enter and exit the accommodating cavity 10 a. It can be understood that, in the present embodiment, the fluid is introduced through the input end 20a and the fluid is discharged through the output end 20b, so as to change the position of the pushing portion 30 in the accommodating chamber 10a, and meanwhile, when the fluid circulation is stopped at both the input end 20a and the output end 20b, the pushing portion 30 stably hovers in the accommodating chamber 10a, so that the grabbing portion 40 abutting against the pushing portion 30 maintains the current position, thereby ensuring the stability in grabbing the object.
