the first transport cylinder 3130 drives the first transport adsorption module 3140 to approach the first material 001 in a certain area (such as in the first stock assembly 200), and then the first transport adsorption module 3140 adsorbs the first material 001; the first conveying cylinder 3130 drives the first conveying suction module 3140 away from this area, and then the first conveying sliding seat 3120 moves along the first conveying sliding rail 3110 (backward in this embodiment), so as to drive the first material 001 to transfer to another area (for example, above the first guide assembly 400); the first transport cylinder 3130 drives the first transport adsorption module 3140 closer to the other region, and then the first transport adsorption module 3140 releases the first material 001 so that the first material 001 falls into the other region. It should be understood that a plurality of conveying adsorption modules can be connected to the piston rod of one conveying cylinder, so that a plurality of materials can be simultaneously adsorbed and conveyed. It should be understood that the first transporting and adsorbing module 3140 may adsorb the first material 001 through an electromagnet, a natural magnet, an air chuck, or the like. It should be understood that a plurality of conveying cylinders may be disposed on one sliding seat, and the plurality of conveying cylinders may respectively and simultaneously perform material transferring operation between areas, so as to increase working efficiency of the apparatus, for example, in this embodiment, the second conveying cylinder, the third conveying cylinder, and the fourth conveying cylinder are all connected to the same sliding seat; or the second carriage assembly 3200, the third carriage assembly 3300, and the fourth carriage assembly 3400 share a common rail and sliding seat. Specifically, the first feeding unit 3000 further includes a second transporting assembly 3200, a third transporting assembly 3300, and a fourth transporting assembly 3400, wherein the second transporting assembly 3200, the third transporting assembly 3300, and the fourth transporting assembly 3400 are all disposed on the base 100, the first transporting assembly 3100 is used for transporting the first material 001 from the first stock assembly 200 to the first guide assembly 400, the second transporting assembly 3200 is used for transporting the first material 001 from the first guide assembly 400 to the position adjusting assembly 500, the third transporting assembly 3300 is used for transporting the first material 001 from the position adjusting assembly 500 to the spot welding assembly 600, and the fourth transporting assembly 3400 is used for transporting the matched material from the spot welding assembly 600 to the storage assembly 1200 (the storage assembly 1200 is used for storing the spot welded matched material).

Referring to fig. 1 and 3, in some embodiments of the present invention, the first transport adsorption module 3140 includes a first transport mounting table 3141, a first transport cylinder 3142, a first transport magnet head 3143, and a first transport limit stop 3144, a piston rod of the first transport cylinder 3130 is fixedly connected to the first transport mounting table 3141, a housing of the first transport cylinder 3142 and the first transport limit stop 3144 are both mounted on the first transport mounting table 3141, the piston rod of the first transport cylinder 3142 is fixedly connected to the first transport magnet head 3143, the first transport magnet head 3143 is used for adsorbing the first material 001, and the first transport limit stop 3144 is used for blocking the first material 001 (and separating the first material 001 from the first transport magnet head 3143).

The operation of the first transport adsorption module 3140 is briefly described as follows: after the first conveying cylinder 3130 drives the first conveying adsorption module 3140 to approach a certain area, the first conveying adsorption cylinder 3142 drives the first conveying magnet head 3143 to extend, and the first conveying magnet head 3143 approaches the first material 001, so that the first material 001 is magnetically attracted to the first conveying magnet head 3143 (at this time, the first conveying limit stop 3144 plays a certain positioning limit role on the first material 001, so that the first material 001 is adsorbed in a fixed posture and cannot move at will); after the first transporting cylinder 3130 drives the first transporting and adsorbing module 3140 to be closer to another area, the first transporting and adsorbing cylinder 3142 drives the first transporting and adsorbing magnet head 3143 to retract, and the first material 001 magnetically attracted on the first transporting and adsorbing magnet head 3143 is blocked by the first transporting and adsorbing limit stop 3144, so that the first material 001 cannot move along with the first transporting and adsorbing magnet head 3143, and finally the first material 001 is far away from the first transporting and adsorbing magnet head 3143, the magnetic attraction force between the first material and the first material is weak, and the first material 001 is not subjected to the magnetic attraction force any more, so that the first transporting and adsorbing module 3140 releases the first material 001, and the first material 001 is placed (or falls into) another area and does not move along with the first transporting assembly 3100 any more. It should be understood that the first transporting and sucking mounting table 3141 may be provided with a plurality of first transporting and sucking cylinders 3142 (on which other structures such as the first transporting and sucking magnet head 3143 are correspondingly connected), so that the same first material 001 can be adsorbed at multiple points, and a plurality of first materials 001 can be adsorbed simultaneously. It should be appreciated that the suction limit stop shapes on different transport suction modules may be different because the attitude of the material may be different in different areas.

According to the above arrangement, when the first conveying cylinder 3130 drives the first conveying adsorption module 3140 to approach an area, the first conveying magnet head 3143 can be guaranteed to be completely abutted against the first material 001 (even if the first conveying cylinder 3130 drives the first conveying adsorption module 3140 to move too much, the first conveying sliding mounting seat 3145 (along the first conveying sliding rod 3146) can only relatively slide to be close to the first conveying mounting table 3141, and the equipment parts or materials cannot be crushed), so that stable adsorption can be ensured, and meanwhile, the (exactly guided) first material 001 posture cannot be changed in the adsorption process (because the first material 001 is completely abutted so as to have a certain limiting and positioning effect, particularly a conveying limit stop matched with a specific shape). It should be understood that the first transport adsorption module 3140 may further be provided with a first transport adsorption elastic member 3147, one end of the first transport adsorption elastic member 3147 is connected to the first transport adsorption mounting table 3141, the other end of the first transport adsorption elastic member 3147 is connected to the first transport adsorption sliding mounting table 3145, and the first transport adsorption elastic member 3147 is used for keeping the first transport adsorption sliding mounting table 3145 away from the first transport adsorption mounting table 3141 (i.e. a reset function); the first transport adsorption module 3140 may also be automatically reset by gravity.

It should be appreciated that in the present embodiment, the second carriage assembly 3200, the third carriage assembly 3300, the fourth carriage assembly 3400 and the first carriage assembly 3100 are substantially identical in structure (different in carriage suction limit stops).

The (second conveying assembly 3200 of the) first feeding unit 3000 conveys the first material 001 from the first guide assembly 400 onto the position adjustment assembly 500, and the (third conveying assembly 3300 of the) first feeding unit 3000 conveys the first material 001 from the position adjustment assembly 500 onto the spot welding assembly 600.

After the first materials 001 are guided, the first materials 001 are all in the same posture, the second conveying assembly 3200 conveys the first materials 001 to the position adjusting assembly 500, and the first materials 001 are positioned at specific positions on the position adjusting assembly 500 through adjustment of the position adjusting assembly 500, so that subsequent conveying and spot welding are facilitated.

Referring to fig. 2 and 7, in some embodiments of the present invention, the position adjustment assembly 500 includes an adjustment table 510, a side Fang Gangti and a side adjuster 530, the adjustment table 510 is disposed on the base 100, the adjustment table 510 is used for placing the first material 001, one side of the adjustment table 510 is provided with a side limiting protrusion 511, the side limiting protrusion 511 is used for abutting against one side of the first material 001, a housing of the side Fang Gangti 520 is mounted on the adjustment table 510, a piston rod of the side Fang Gangti 520 is connected with the side adjuster 530, and the side adjuster 530 is used for abutting against the other side of the first material 001.

The operation of the position adjustment assembly 500 (adjusting the left and right positions) is briefly described as follows:

when the first material 001 is placed on the adjustment placing table 510, the side Fang Gangti 520 drives the side adjusting member 530 (a rod) to move, so that the side adjusting member 530 abuts against the other side of the first material 001 and drives the first material 001 to continue to be transported (along the left-right direction), and finally, one side of the first material 001 abuts against the side limiting protrusion 511, thereby adjusting the left-right position of the first material 001 to a specific position.

Referring to fig. 2 and 7, in some embodiments of the present invention, the position adjustment assembly 500 further includes a side rail 540 and a side rail seat 550, the side rail 540 is disposed on the base 100, the side rail seat 550 and the side rail 540 are slidably coupled, the piston rod of the side Fang Gangti 520 is coupled to the side rail seat 550, and the side rail seat 550 and the side adjustment member 530 are coupled.

As described above, by providing the side rail 540 and the side sliding seat 550, the cylinder driving side adjuster 530 operates more stably, and the position adjustment is more accurate, without being deflected at will; and a plurality of side adjusting members 530 (a plurality of side limiting protrusions 511 are correspondingly arranged on the adjusting and placing table 510) can be arranged on the side sliding seat 550, so that the left and right positions of a plurality of first materials 001 can be simultaneously adjusted. It should be appreciated that both the slide rail and the slide seat may be replaced with each other in their installed positions, such as in the present embodiment, the side slide seat 550 may be provided on the base 100, and the side slide rail 540 and the side adjuster 530 may be coupled.

Referring to fig. 2 and 7, in some embodiments of the present invention, the position adjustment assembly 500 further includes a forward cylinder 560 and a forward adjuster 570, the housing of the forward cylinder 560 being mounted on the base 100, the piston rod of the forward cylinder 560 being connected to the forward adjuster 570, the forward adjuster 570 being adapted to abut the front side of the first material 001.

The operation of the position adjustment assembly 500 (adjustment of the front-rear position) may refer to the operation of the position adjustment assembly 500 (adjustment of the left-right position); in contrast, the first material 001 of the present embodiment is an L-shaped part, and when the first material 001 is placed on the adjustment placing table 510, a side plate thereof is suspended, so that the adjustment placing table 510 naturally limits one side of the first material 001 in the front-rear direction (without providing a structure like the side limiting protrusions 511). Referring to the above, the position adjusting assembly 500 may further include a front rail 580 and a front sliding seat 590, the front rail 580 is disposed on the base 100, the front sliding seat 590 is slidably connected to the front rail 580, the piston rod of the front cylinder 560 is connected to the front sliding seat 590, and the front sliding seat 590 is connected to the front adjusting member 570. It is to be understood that a sensor may also be provided to detect the position of the first material 001.

Referring to fig. 1 and 6, in some embodiments of the present invention, the first guide assembly 400 includes a conveyor belt 410 and a height limiting bar 420, both the conveyor belt 410 and the height limiting bar 420 are disposed on the base 100, the height limiting bar 420 is located above the conveyor belt 410, the height limiting bar 420 is spaced apart from the conveyor belt 410 by a designated distance (the designated distance is greater than the width of the narrow plate of the L-shaped first material 001 and less than the width of the wide plate of the L-shaped first material 001), the conveyor belt 410 is used to convey the first material 001, and the height limiting bar 420 is used to limit the first material 001 having a height higher than the designated distance from being conveyed by the conveyor belt 410 (because the first material 001 having a height higher than the designated distance is turned over by the height limiting bar 420, to become the first material 001 having a height not higher than the designated distance).

Since the first material 001 is L-shaped (other similar shapes are also applicable, that is, the first material 001 is formed by connecting two plates at a certain angle to each other), the L-shape is placed on the conveyor belt 410, when the L-shaped first material 001 hits the height limiting strip 420, the height of the erected plate of the L-shaped first material 001 is too high (or too wide) to be blocked by the height limiting strip 420, when the L-shaped first material 001 continues to move backwards along with the conveyor belt 410, the L-shaped first material 001 rotates counterclockwise by 90 degrees due to the action of the height limiting strip 420 (the designated distance is smaller than the width of the wider plate of the L-shaped first material 001), so that the plate of the L-shaped first material 001 originally erected becomes a lying flat state (the other plate of the original lying flat state becomes an erect state), and the turned first material 001 can smoothly pass through the gap between the height limiting strip 420 and the conveyor belt 410 and cannot be blocked by the height limiting strip 420 due to the designated distance being greater than the width of the narrower plate of the L-shaped first material 001. It should be understood that the first materials 001 stacked together may also be separated by a reasonable set of specified distances. Therefore, the height limiting strips 420 are simple and practical, and can be guided through a simple structure by utilizing the special structure and the size of the materials, so that the design is ingenious.

Referring to fig. 2 and 6, in some embodiments of the present invention, the first guide assembly 400 further includes a first position detection sensor 430 and an ejection cylinder 440, both of the first position detection sensor 430 and the ejection cylinder 440 are disposed on the base 100, the first position detection sensor 430 is used to detect the first material 001 in the wrong placement state, and the ejection cylinder 440 is used to eject the first material 001 in the wrong placement state out of the conveyor belt 410.

When the first material 001 is not placed in an L shape, but placed in a J shape (and the L placement are substantially mirror symmetry) or placed in a "], the height limiting bar 420 cannot perform the guiding function, and at this time, the first position detecting sensor 430 detects that the first material 001 is placed in an incorrect state, and the ejection cylinder 440 ejects the first material 001 out of the conveyor belt 410. It should be appreciated that the first position detecting sensor 430 may be provided in plurality to detect the placement state of the first material 001 in more precise detail. It should be understood that, since the first material 001 is stored in an L-shape (original factory state), the first material 001 rarely has a J-shape placement error. It should be appreciated that the first guide assembly 400 further includes a speaker gathering structure 450, where the speaker gathering structure 450 is disposed on the base 100 and beside the conveyor belt 410, and is similar to a bell mouth structure, such that the first material 001 is gathered (approximately adjusting the left and right positions of the first material 001).

Referring to fig. 2 and 6, in some embodiments of the present invention, the first alignment assembly 400 further includes an alignment conveyance module 460 and a flipping conveyance module 470, each of the alignment conveyance module 460 and the flipping conveyance module 470 being disposed on the base 100, the alignment conveyance module 460 being configured to convey the first material 001 from the conveyor 410 onto the flipping conveyance module 470, the flipping conveyance module 470 being configured to invert the first material 001.

The structure and operation of the alignment transport module 460 is described above with reference to the first transport assembly 3100; it is to be appreciated that a sensor may be provided at the end of the conveyor belt 410 that guides the conveyor module 460 to convey the first material 001 when the sensor detects that the end of the conveyor belt 410 conveys the first material 001. In this embodiment, the first material 001 needs to lie prone (i.e. its vertical plate is downward rather than upward) to be matched with the second material 002 for spot welding, so after the above-mentioned height limiting bar 420 is guided, the first material 001 needs to be turned over, so that its vertical plate is downward, and the turning and conveying module 470 needs to be provided.

Referring to fig. 2 and 6, in some embodiments of the present invention, the overturn carrying module 470 includes an overturn jaw 471, an overturn driving member 472, a first jacking cylinder 473 and a first jacking support 474, the housing of the first jacking cylinder 473 is mounted on the base 100, the piston rod of the first jacking cylinder 473 is connected with the first jacking support 474, the first jacking support 474 is used for jacking the first material 001, the overturn driving member 472 is disposed on the base 100, the overturn driving member 472 is in transmission connection with the overturn jaw 471, and the overturn driving member 472 is used for driving the overturn jaw 471 to approach, clamp and overturn the first material 001 being jacked.

The flipping operation of the flipping transport module 470 is briefly described as follows:

the first lifting cylinder 473 drives the first lifting support 474 to lift, and the first lifting support 474 lifts one first material 001 placed on the concave-convex structure so that the first material 001 is far away from the concave-convex structure (prevents the concave-convex structure from obstructing the overturning of the first material 001); the flip driving member 472 drives the flip jaw 471 (right-hand movement) to approach the first material 001; the flip driving member 472 drives the flip jaw 471 to clamp the first material 001; the overturning driving part 472 drives the overturning clamping jaw 471 to overturn the first material 001, so that the upright plate of the first material 001 faces downwards; the overturning driving part 472 drives the overturning clamping jaw 471 to release the first material 001, so that the overturned first material 001 falls onto the first jacking supporting piece 474; the flip driving member 472 drives the flip jaw 471 (left-shifted) away from the first material 001 (to be later turned back to the original state); the first lifting cylinder 473 drives the first lifting support 474 downward, eventually causing the inverted first material 001 to be replaced on the concave-convex structure.

It should be understood that the flip driving member 472 is formed by combining a plurality of parts, and can drive the flip clamping jaw 471 to move left and right (for example, a sliding rail and sliding block structure driven by an air cylinder to move, the flip clamping jaw 471 is arranged on the sliding block), can drive the flip clamping jaw 471 to open or clamp, and can also drive the flip clamping jaw 471 to rotate (for example, the air cylinder drives the rack to move, and drives the gear to rotate, so as to drive the flip clamping jaw 471 to rotate).

Referring to fig. 2 and 6, in some embodiments of the present invention, the overturning and conveying module 470 further includes a conveying strip 475, a conveying table 476, an overturning and conveying sliding seat 478, an overturning and backward moving cylinder 479, and an overturning and lifting cylinder (which is hidden by the conveying table 476 in the drawing), wherein a first concave-convex structure 110 is disposed on the base 100, a second concave-convex structure 475a is disposed on the conveying strip 475, the first concave-convex structure 110 and the second concave-convex structure 475a are both used for placing the first material 001, a shell of the overturning and lifting cylinder is mounted on the base 100, a piston rod of the overturning and lifting cylinder is fixedly connected with the conveying table 476, the overturning and conveying sliding seat 477 is disposed on the conveying table 476, the overturning and lifting sliding seat 478 is slidably connected with the overturning and conveying sliding seat 477, a piston rod of the overturning and backward moving cylinder 479 is fixedly connected with the overturning and lifting cylinder 478, the concave-convex structure 475 is disposed on the overturning and lifting cylinder is used for lifting the first material 001 (such that the first material 001 is separated from the first concave-convex structure 110, the first material 001 is placed on the second cylinder 479 for driving the first material to move to the first material 001.

The following briefly describes the transport operation of the reverse transport module 470:

The guide conveying module 460 conveys the first material 001 after guide to the first concave-convex structure 110 of the base 100 (a sensor can be arranged to detect whether the first material 001 is in place or not, and then conveying work is executed); the turning lifting cylinder drives the conveying table 476 to lift, and drives the turning sliding rail 477 (and the turning back moving cylinder 479) on the conveying table 476, the turning sliding seat 478 on the turning sliding rail 477, the conveying bar 475 on the turning sliding seat 478 and the second concave-convex structure 475a on the conveying bar 475 to lift together, so that the first and the second concave-convex structures 475a on the conveying bar 475 finally support the first material 001, and the first material 001 is far away from the base 100 (above the first concave-convex structure 110); the turning back moving cylinder 479 drives the turning sliding seat 478 (sliding relative to the turning sliding rail 477) to move back, so as to drive the conveying strip 475 on the turning sliding seat 478, the second concave-convex structure 475a on the conveying strip 475 and the first material 001 on the second concave-convex structure 475a to move back together, and finally, the first material 001 is moved to the position above the second first concave-convex structure 110; the turning lifting cylinder drives the conveying table 476 to descend so as to drive the parts and the first material 001 on the second concave-convex structure 475a to descend together, and finally, the first material 001 is replaced on (the second concave-convex structure on) the base 100, and the conveying strip 475 is far away from the first material 001 (the conveying strip 475 is positioned below the first material 001); the turning back moving cylinder 479 drives the turning sliding seat 478 (sliding relative to the turning sliding rail 477) to move forward, so as to drive the conveying strip 475 on the turning sliding seat 478 and the second concave-convex structure 475a on the conveying strip 475 to move forward together, and finally, the second concave-convex structure 475a moves to the lower part of the first material 001; the turning lifting cylinder drives the conveying table 476 to lift, so that the parts are lifted together, and finally, a second concave-convex structure 475a on the conveying strip 475 supports the first material 001, and the first material 001 is far away from the base 100 (above the second first concave-convex structure 110); in this cycle, the first material 001 is carried back.

It should be appreciated that the reverse conveyance module 470 may convey a plurality of first materials 001 at a time. It should be understood that the concave-convex structure has concave parts or convex parts or a combined structure of the concave parts and the convex parts, is suitable for supporting the first material 001, is embedded with the shape and the placement posture of the first material 001, and has a certain limiting and positioning effect on the first material 001. It should be understood that, because the first material 001 needs to be turned over during the conveying process, the placing posture of the first material 001 changes, so that the concave-convex structure (front-back concave structure) for supporting the first material 001 has a certain difference. It should be understood that a sensor may be provided to detect whether the first material 001 is placed on the last first concave-convex structure 110 of the base 100, and if so, the first material 001 is timely carried away by (the second carrying assembly 3200 of) the first feeding unit 3000, thereby preventing stacking of the first material 001 therein.

Referring to fig. 2 and 6, in some embodiments of the present invention, the overturning and conveying module 470 further includes a position auxiliary adjusting cylinder 4710 and a push rod 4711, wherein a housing of the position auxiliary adjusting cylinder 4710 is mounted on the base 100, a piston rod of the position auxiliary adjusting cylinder 4710 is connected to the push rod 4711, and the push rod 4711 is used to jack up one side of the first material 001 (such that one side of the first material 001 is flattened and is more easily absorbed and conveyed by the conveying assembly).

Because the first material 001 is placed in a shape of "≡after being turned over, and when spot welding is performed, the first material 001 is required to be placed in a shape of" factory ", so that the position auxiliary adjusting cylinder 4710 and the ejector rod 4711 are arranged, the posture of the first material 001 on the base 100 is adjusted, the first feeding unit 3000 (the second conveying adsorption module of the second conveying assembly 3200) is convenient to grasp, and the first material 001 is conveyed to the spot welding assembly 600 (or the position adjusting assembly 500) without additional posture adjustment, and the phenomenon that the first material 001 moves randomly when being placed is reduced.

The working process is briefly described: before the first feeding unit 3000 conveys the first material 001 on the first concave-convex structure 110, the position auxiliary adjusting cylinder 4710 drives the ejector rod 4711 to ascend, the ejector rod 4711 abuts against the inner side surface of the first material 001, and one side plate of the first material 001 is lifted, so that the original 'type' placement of the first material 001 is changed into 'factory' type placement; the first feeding unit 3000 carries away the first material 001; the position-assist adjustment cylinder 4710 drives the jack 4711 to retract. It should be understood that if the first feeding unit 3000 conveys a plurality of first materials 001 at a time, a plurality of lifters 4711 are correspondingly provided, and the plurality of lifters 4711 may be connected to one position auxiliary adjustment cylinder 4710 through one mounting table. It should be appreciated that the lift pins 4711 raise a side plate of the first material 001 such that the first material 001 is generally "factory" -shaped, but may not be entirely "factory" -shaped (i.e., may not be entirely horizontal on one side thereof), but may be slightly biased to be "a" shaped to prevent the first material 001 from sliding off.

Referring to fig. 2 and 6, in some embodiments of the present invention, the first guide assembly 400 further includes a folding baffle 480, a folding cylinder 490, and a folding push plate 4100, the folding baffle 480 is disposed on the base 100, the folding baffle 480 is used to abut against one side of the first material 001, a housing of the folding cylinder 490 is mounted on the base 100, a piston rod of the folding cylinder 490 is connected to the folding push plate 4100, and the folding push plate 4100 is used to abut against the other side of the first material 001.

The working process is briefly described: before the first feeding unit 3000 conveys the first material 001 on the first concave-convex structure 110, the folding cylinder 490 drives the folding push plate 4100 to move towards a direction approaching to the first material 001, so that the folding push plate 4100 abuts against the other side of the first material 001, and the folding push plate 4100 pushes the first material 001 to move, and finally, one side of the first material 001 abuts against the receiving folding baffle 480 (may be just approaching, but not abutting really, and the folding baffle 480 plays a role in preventing); the first feeding unit 3000 carries away the first material 001; the folding cylinder 490 drives the folding push plate 4100 to return. The arrangement thus serves to adjust the position of the first material 001.

The following steps: the third feeding unit 1000 drives the third sliding seat 1020 to slide on the third sliding rail 1010 (leftwards), so as to drive the spot welding table 610 on the third sliding seat 1020 and the matched materials spot-welded on the spot welding table 610 to return; the (fourth carriage assembly 3400 of the) first feeding unit 3000 carries the mating materials on the spot welding stage 610 onto the stock assembly 1200, awaiting further processing.

It is to be appreciated that the fifth transport assembly 8100 and sixth transport assembly 8200 are similar in structure to the first transport assembly 3100 (transport adsorption modules are different and otherwise identical).

Referring to fig. 3 and 11, in some embodiments of the present invention, the fifth transfer assembly 8100 includes a fifth transfer slide 8110, a fifth transfer slide 8120, a fifth transfer cylinder 8130, and a fifth transfer adsorption module 8140, the fifth transfer slide 8110 being disposed on the base 100, the fifth transfer slide 8120 and the fifth transfer slide 8110 being slidably coupled, an outer shell of the fifth transfer cylinder 8130 being mounted on the fifth transfer slide 8120, a piston rod of the fifth transfer cylinder 8130 being fixedly coupled to the fifth transfer adsorption module 8140, the fifth transfer adsorption module 8140 being for adsorbing the second material 002.

The structure and operation of fifth carriage assembly 8100 are described with reference to first carriage assembly 3100.

Referring to fig. 10 and 11, in some embodiments of the present invention, the fifth transport suction module 8140 includes a fifth transport suction stage 8141, a fifth position adjustment motor 8142, a fifth position adjustment mount 8143, and a suction member 8144, a piston rod of the fifth transport cylinder 8130 is fixedly connected to the fifth transport suction stage 8141, the fifth position adjustment mount 8143 is rotatably connected to the fifth transport suction stage 8141, the fifth position adjustment motor 8142 is in driving connection with the fifth position adjustment mount 8143, the suction member 8144 is mounted on the fifth position adjustment mount 8143, and the fifth position adjustment motor 8142 is used for adjusting a suction angle of the suction member 8144.

Because the second storage tank 710 is fixed in size (particularly, the width of the second storage tank is fixed), the placing posture of the second material 002 may be different when placing the second material 002 with different widths (for example, when the width of the second material 002 is smaller than the width of the storage space in the second storage tank 710, the second material 002 may be laid flat in the second storage tank 710, and when the width of the second material 002 is larger than the width of the storage space in the second storage tank 710, the second material 002 may be placed in the second storage tank 710 only in an inclined manner, and the larger the width of the second material 002, the larger the angle of inclination of the second material 002. Therefore, the fifth position adjusting motor 8142 can drive the fifth position adjusting mounting seat 8143 to rotate, so that the adsorption angle of the adsorption member 8144 is adjusted, and the adsorption device is suitable for adsorbing the second materials 002 with different widths (different inclination angles).

In this embodiment, the fifth conveying adsorption platform 8141 is used as a base, the fifth position adjusting mounting seat 8143 and the fifth conveying adsorption platform 8141 are rotationally connected, two fifth position adjusting mounting seats 8143 are provided and can simultaneously adsorb two second materials 002, one ends of the two fifth position adjusting mounting seats 8143 are connected with belt wheels, and the fifth position adjusting motor 8142 is connected with the two belt wheels through a belt, so that the two fifth position adjusting mounting seats 8143 can be simultaneously driven to rotate by the same angle. It is to be understood that the suction member 8144 (and the sixth transport assembly 8200) may be made to suck the second material 002 by an electromagnet or an air suction cup.

Referring to fig. 11, in some embodiments of the present invention, the fifth transport suction module 8140 further includes a fifth sensor 8145 and a sensing block 8146, the sensing block 8146 and the fifth position adjustment mount 8143 are fixedly connected, the fifth sensor 8145 is mounted on the fifth transport suction table 8141, and the fifth sensor 8145 is used to detect the position of the sensing block 8146.

The sensing block 8146 rotates along with the rotation of the fifth position adjustment mounting seat 8143, and the state of the sensing block 8146 is detected by the fifth sensor 8145, so that the rotation angle of the fifth position adjustment mounting seat 8143 can be detected, thereby facilitating the adjustment of the suction angle of the suction member 8144. In this embodiment, the fifth sensor 8145 is a photoelectric switch, so that the fifth position adjustment mounting base 8143 (the fifth position adjustment motor 8142) returns to the original position; in particular, the adsorption angle may be adjusted when the second material 002 in the second stock assembly 700 is adsorbed, and the adsorbing member 8144 may be returned to its original position (i.e., the sensing block 8146 rotates to the middle of the photoelectric switch to shut off the photoelectric switch) when the second material 002 is placed on the second guide assembly 900.

Referring to fig. 2 and 9, in some embodiments of the present invention, the second centering assembly 900 includes a second centering placement table 910, a second centering inclined plate 920, a second centering mounting seat 930, and a second centering cylinder 940, the second centering placement table 910 is disposed on the base 100, the second centering placement table 910 is used for placing the second material 002, the second centering placement table 910 is provided with a centering through groove 911, the centering through groove 911 is located at a side of the second material 002, a housing of the second centering cylinder 940 is mounted on the base 100, a piston rod of the second centering cylinder 940 is fixedly connected with the second centering mounting seat 930, the second centering inclined plate 920 is mounted on the second centering mounting seat 930, the second centering inclined plate 920 is disposed with a centering inclined surface 921, the second centering inclined plate 920 is protruded onto the second centering placement table 910 through the centering through groove 911, and the centering inclined surface 921 is used for abutting against a side wall of the second material 002.

It should be appreciated that the sixth transport adsorption module of the sixth transport assembly 8200 includes a compact to facilitate depressing the second material 002 while transporting the second material 002 to assist in directing the second material 002. It should be understood that, since the guiding inclined plate is provided, the range surrounded by the uppermost end of the guiding inclined plate 921 is larger than that of the second inclined plate, and the range surrounded by the lowermost end of the guiding inclined plate 921 is substantially as large as that of the second inclined plate, that is, the range surrounded by the guiding inclined plate becomes smaller and smaller when the guiding inclined plate rises.

The operation of the second guide assembly 900 is briefly described as follows:

the fifth transfer assembly 8100 of the second feeding unit 8000 transfers the second material 002 from the second stock assembly 700 onto the second alignment and placement stage 910; the second guiding cylinder 940 drives the second guiding mounting base 930 to rise, and drives the plurality of second guiding inclined plates 920 on the second guiding mounting base 930 to rise together, so that the range surrounded by the guiding inclined plane 921 is smaller and smaller; until the guide inclined plane 921 abuts against the second material 002, the second material 002 is pushed to move (or the second material 002 slides down relatively along the guide inclined plane 921), so that the position of the second material 002 is adjusted; the second guide cylinder 940 drives the second guide mounting base 930 to descend and drives the second guide inclined plate 920 to descend together; the sixth conveying assembly 8200 of the second feeding unit 8000 conveys the second material 002 from the second guide placement stage 910 onto the spot welding assembly 600 (spot welding stage 610) such that the second material 002 abuts the first material 001. It should be understood that, in the actual guiding process, multiple guiding operations (the second guiding cylinder 940 drives the second guiding mounting base 930 to lift and lower multiple times) may be performed, so as to ensure that the position of the second material 002 is well adjusted. It should be understood that, since the second material 002 is in a sheet shape, and is very soft, when the second material 002 in a sheet shape is closely attached to the table surface of the second guide table 910, the second material 002 is easy to bend and does not move (friction force effect) when an external force is applied (particularly, the position of the second material 002 in the left-right direction is adjusted in the length direction or the left-right direction), so that the adjustment effect is not good when a structure similar to that of the position adjustment assembly 500 is adopted; when the second guiding assembly 900 of this embodiment is adopted, when the position of the second material 002 is not aligned, the second guiding inclined plate 920 lifts the second material 002, so that the second material 002 is not closely attached to the table top, and bears the gravity of a part of the second material 002, so that the friction between the second material 002 and the table top is reduced, the second material 002 is easier to move, and the position of the second material 002 is better adjusted (especially, after the guiding is performed for many times, the guiding effect is good). It should be appreciated that when the sixth conveyance assembly 8200 conveys the second material 002, the sixth conveyance assembly 8200 presses the second material 002, which can help the second material 002 to better adjust its position.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of one of ordinary skill in the art without departing from the spirit of the present invention.
