In this embodiment, the detecting end of the sensor 142 is disposed at the bottom of the feeder taking mechanism 141, and the detecting end is used to abut against the topmost printing substrate, so as to determine whether the material below the feeder taking mechanism 141 reaches the height position of the detecting end of the sensor 142 when the feeder taking mechanism 141 is located above the preset position, and the fixed end of the sensor 142 extends into the feeder taking mechanism 141. Generally, when the feeding and reclaiming mechanism 141 moves to a position above the printing substrate to be reclaimed, the detecting end of the sensor 142 abuts against the top printing substrate, and when the top printing substrate is separated from the detecting end of the sensor 142 after multiple reclaiming, the sensor 142 sends a signal to the controller, and the controller controls the lifting mechanism 130 to operate according to the signal until the top printing substrate abuts against the detecting end again; and repeating the feeding process until the feeding is finished.

Specifically, one end of the gas blowing pipe 143 is disposed outside the feeder 141 and corresponds to a height position of the detection end of the sensor 142, and the other end of the gas blowing pipe 143 is connected to a gas blowing device (not shown); the blowing device is used for outputting airflow so that the airflow is output to the edge of the printing substrate through the blowing pipe, and therefore adjacent printing substrates are separated from each other, and the picking and placing process of a single printing substrate is facilitated. It is worth mentioning that the blowing device and the pneumatic device can be the same device, namely, the blowing device and the pneumatic device are integrated inside the flight material taking mechanism; the blowing device may be independent of the feeder and may blow air through the blowing tube 143, which is not limited in the present invention.

When the material supporting platform 120 supports the stacked printing substrates, the first positioning plate 151 and the second positioning plate 152 can move towards the direction close to the center of the material supporting platform 120 at the same time until the gap between the first positioning plate 151 and the second positioning plate 152 is the width of the printing substrate along the gap direction, two side edges of each stacked printing substrate are gradually aligned and leveled under the abutting action of the first positioning plate 151 and the second positioning plate 152, meanwhile, the printing substrate moves to abut against the third positioning plate 153 under the driving of the feeding belt 124, and the front edge of each printing substrate is gradually aligned and leveled under the abutting action of the third positioning plate 153. During the feeding process, a single printing substrate will stably rise under the positioning action of the first positioning plate 151, the second positioning plate 152 and the third positioning plate 153 without deflection. It should be noted that the "center of the material supporting platform 120" should be the center of the structure actually carrying the material, since the material is actually carried by the two bases 122 and the two feeding belts 124 in this embodiment, the "center of the material supporting platform 120" in this embodiment is actually the center position between the two feeding belts 124.

With reference to fig. 2 and fig. 3, and with reference to fig. 4 to fig. 8, the positioning driving mechanism 160 includes a first lead screw 161, a first guide bar 162, and a first motor 163. The first lead screw 161 is mounted on the frame 110, and the whole of the first lead screw extends in a direction perpendicular to the first positioning plate 151, and two ends of the first lead screw 161 are respectively supported on the two side plates 111. The first lead screw 161 includes a first portion 1611 and a second portion 1612, and the first portion 1611 and the second portion 1612 are oppositely rotated. The first positioning plate 151 is threadedly coupled to a first portion of the first lead screw 161, and the second positioning plate 152 is threadedly coupled to a second portion of the first lead screw 161. In this embodiment, the first portion 1611 and the second portion 1612 are two independent units, and the first portion 1611 and the second portion 1612 are coaxially fixed by a connector 1613 to realize coaxial rotation; it will be appreciated that in other embodiments of the invention, the first portion and the second portion may be two portions of the same screw structure with opposite thread directions.

The first guide bar 162 is mounted on the frame 110 and parallel to the first screw 161, and two ends of the first guide bar 162 are respectively supported on the two side plates 111. The first guide bar 162 is sleeved with the first positioning plate 151 and the second positioning plate 152, so that the first positioning plate 151 and the second positioning plate 152 are slidably engaged with the frame 110 in a direction parallel to the extending direction of the first screw 161. The first motor 163 is installed on the frame 110, an output end of the first motor 163 is connected to one end of the first screw 161, and the first motor 163 is configured to drive the first screw 161 to rotate, so that the first positioning plate 151 and the second positioning plate 152 move towards a direction close to the center of the material holding platform 120, or the first positioning plate 151 and the second positioning plate 152 move towards a direction away from the center of the material holding platform 120. In this embodiment, the first motor 163 is indirectly connected to the first screw 161 via a screw 164 installed between the two side plates 111 and a timing belt (not shown) wound around an end of the screw 164 and an end of the first screw 161.

Further, in order to facilitate the stacked printing substrates to travel on the feeding belt 124 so as to be positioned by the third positioning plate 153, the feeding module further includes a material driving mechanism 170, referring to fig. 2 in combination with fig. 3 to 8, the material driving mechanism 170 is connected to the pulley 123, and is configured to drive the pulley 123 to rotate so as to synchronize the feeding belt 124, so that each printing substrate moves from one end away from the third positioning plate 153 to abut against the third positioning plate 153, so as to complete the positioning of each printing substrate by the third positioning plate 153. In this embodiment, the material driving mechanism 170 includes a first gear 171, a second gear 172, and a handwheel 173. The first gear 171 is coaxially fixed to the pulley 123 at an end away from the third positioning plate 153; the second gear 172 is rotatably mounted to the frame 110 and engaged with the first gear 171; the hand wheel 173 is connected to the second gear 172, so that the worker can rotate the hand wheel 173 to rotate the second gear 172 and the first gear 171 synchronously, so as to rotate the pulley 123. The hand wheel 173 may be directly connected to the second gear, or may be indirectly connected to the second gear through an intermediate transmission device such as a gear set or a bevel gear set.

The operation of the feeding module 100 provided in the above embodiment will be briefly described below with reference to the drawings, taking the detection end of the sensor 142 higher than the height of the initially stacked printing substrates as an example.

In an initial state, the material supporting platform 120 is located at a bottom position of the frame 110, and the first positioning plate 151 and the second positioning plate 152 are respectively located at one end of the first portion 1611 and one end of the second portion 1612 away from the center of the material supporting platform 120.

When the feeding process needs to be performed, the stacked printing substrates are firstly conveyed to the position above the feeding belt 124 through an external pre-feeding mechanism, or the printing substrates are directly stacked on the feeding belt 124. Then, the handwheel 173 is rotated to make the feeding belt 124 drive the stacked printing substrates to move to abut against the first positioning plate 151, and then each printing substrate is positioned along the proceeding direction; meanwhile, the positioning driving mechanism 160 drives the first positioning plate 151 and the second positioning plate 152 to move towards the direction close to the center of the material holding platform 120 at the same time, until the gap between the first positioning plate 151 and the second positioning plate 152 is equal to the width of the printing substrate along the gap direction, and then each printing substrate is positioned along the direction perpendicular to the advancing direction.

The material taking mechanism 140 moves to the upper part of the printing substrate, the detection end part of the sensor 142 abuts against the printing substrate at the top, the suction cup 1411 extends downwards to adsorb the printing substrate, and then the material taking mechanism 140 conveys the printing substrate to the feeding module 200 to complete the taking and placing process of the single printing substrate. When the material taking process is repeated for a plurality of times until the material taking mechanism is positioned above the printing base material and the stacked printing base material is separated from the detection end part of the sensor 142, the material taking process is interrupted; at this time, the controller drives the lifting mechanism 130 to move so as to raise the material supporting platform 120 as a whole until the top printed substrate is again abutted to the above-mentioned detecting end, and the material taking mechanism 140 continues to take the material. Therefore, the number of the printing substrates on the material bearing platform 120 is continuously reduced, and the material bearing platform 120 is continuously lifted until all the printing substrates are loaded.

After the loading is finished, the first positioning plate 151 and the second positioning plate 152 respectively move to one end far away from the center of the material bearing platform 120 under the driving of the positioning driving mechanism 160; the loading platform 120 is driven by the lifting mechanism 130 to descend to its initial position, and the first gear 171 is engaged with the second gear 172 to wait for the loading process of the next batch of printed substrates.

The operation of initially stacking the printed substrates at a height lower than the probing end of the sensor 142 is substantially the same as the above-mentioned operation, and is not described herein.

The feeding module 100 can make the placing postures of the printed substrates consistent when feeding through the positioning mechanism 150 and the positioning driving mechanism 160, and can avoid the disadvantage that the printed patterns are different at the printing positions of different printed substrates. In addition, the first positioning plate 151 and the second positioning plate 152 are driven by the same motor through the first lead screw 161, so that synchronous motion can be realized, and various defects such as circuit cost increase, occupied large installation space, electric quantity waste and the like caused by independent driving of the two motors are avoided.

Next, a description will be given of a specific structure of the aforementioned feeder module 200.

In this embodiment, the frame of the feeding module 200 and the frame 110 of the loading module 100 are the same mechanism, but it should be understood that in other embodiments, the frame of the feeding module 200 may be another independent mechanism. The feeding wheel 220 is rotatably mounted to the frame 110, and the feeding wheel driving device 230 is fixedly mounted to the frame 110 and is used for driving the feeding wheel 220 to rotate.

In this embodiment, the feeding wheel driving device 230 is a motor, and it is understood that in other embodiments of the present invention, the feeding wheel driving device 230 may be any other device capable of realizing a rotational output, such as a rotary cylinder.

With reference to the above-mentioned pinch roller mounting base 240, with continued reference to fig. 10 and 11, the pinch roller mounting base 240 is rotatably mounted to the frame 110 via a guide shaft 212. Specifically, the guide shaft 212 is disposed parallel to the rotation axis of the feeding wheel 220, and both ends of the guide shaft are fixed to the two side plates 111. The pinch roller mount 240 includes two mounting side plates 241 disposed opposite to each other, and a mounting top plate 242 disposed between the two mounting side plates 241. The two mounting side plates 241 are respectively rotatably sleeved on the guide shaft 212, and two ends of the mounting top plate 242 are respectively fixed to the two mounting side plates 241, so that the pressing wheel mounting base 240 is parallel to the rotation axis of the feeding wheel 220.

Referring to fig. 12, which shows a partially enlarged schematic view of a portion B in fig. 11, referring to fig. 9 to 11, the first elastic member 260 is disposed at an end of the nip wheel mounting base 240 away from the feeding wheel 220, and two ends of the first elastic member 260 are respectively connected to the frame 110 and the nip wheel mounting base 240.

First elastic component 260 is located between installation roof 242 and fixing base 261, and its both ends respectively with the installation roof 242 and the fixing base 261 butt of swage wheel mount pad 240, be promptly: the first elastic member 260 indirectly abuts against the frame 110 through the fixing seat 261. Then, in the case where no printing substrate is disposed between the feeding wheel 220 and the nip wheel 250, the nip wheel 250 will abut against the feeding wheel 220 under the elastic action of the first elastic member 260, that is: the gap between the feed wheel 220 and the nip wheel 250 is zero; in the case where the printing substrate is conveyed between the feeding wheel 220 and the nip wheel 250, the gap between the feeding wheel 220 and the nip wheel 250 may vary with the thickness variation between different batches of printing substrates, and the nip wheel 250 always presses and holds the printing substrate under the action of the first elastic member 260. In this embodiment, the first elastic member 260 is a spring, and it should be understood that in other embodiments of the present invention, the first elastic member may also be other elastic elements such as rubber, silicon gel, etc., which are not limited herein.

Both ends of the first elastic member 260 are respectively abutted against the mounting top plate 242 of the pinch roller mounting base 240 and one end of the first tensioning device 262 close to the pinch roller mounting base 240.

Furthermore, in order to prevent the first tensioning device 262 from being easily loosened, the feeding module 200 further includes a first anti-loose device 2621, where the first anti-loose device 2621 is used to tightly lock and fix the first tensioning device 262 to the fixing seat 261, so as to prevent looseness. In this embodiment, the first anti-loose device 2621 is a nut, and generally, the nut locks and fixes the first tensioning device 262 to the fixed seat 261; when the tension of the first elastic member 260 needs to be adjusted, the nut is loosened, the first tensioning device 262 is rotated to adjust the tension of the first elastic member 260 to a desired state, and then the nut is tightened.

Still further, in order to prevent the first elastic member 260 from being easily separated from the mounting top plate 242 and the first tensioning device 262, an installation groove is formed in one end of the mounting top plate 242 close to the fixed seat 261, a first installation portion 2622 is coaxially and fixedly connected to one end of the first tensioning device 262 close to the mounting top plate 242, and a diameter of the first installation portion 2622 is smaller than a diameter of one end of the first tensioning device 262 close to the mounting top plate 242. One end of the first elastic member 260 is received in the mounting groove, and the other end is sleeved on the first mounting portion 2622 and abuts against one end of the first tensioning device 262 close to the mounting top plate 242.

In this embodiment, the second elastic member 2725 is a spring, and two ends of the spring are respectively abutted against the movable plate 2722 and the second connecting seat 2721, but it should be understood that in other embodiments of the present invention, the second elastic member may also be other elastic elements such as rubber, silica gel, etc., which are not limited herein. Meanwhile, it should be understood that: in other embodiments of the present invention, the second position-limiting device 2724 may also have any other structure as long as it is connected to the first position-limiting device and is abutted against the second connecting seat under the elastic action of the second elastic member 2725.

Further, to facilitate adjustment of the tension of the second resilient member 2725, the feeding module 200 further includes a second tensioning device 2726. One end of the second tensioning device 2726 is disposed between the movable plate 2722 and the second connecting seat 2721, and the other end extends in a direction away from the movable plate 2722 and is threadedly connected to the second connecting seat 2721. Two ends of the second elastic member 2725 are respectively abutted against the movable plate 2722 and one end of the second tensioning device close to the movable plate, that is: the second resilient member 2725 indirectly abuts against the second attachment seat 2721 through a second tensioning device 2726.

Further, in order to prevent the second tensioning device 2726 from being easily loosened, the feeding module 200 further includes a second anti-loosening device 2727, and the second anti-loosening device 2727 is used for locking and fixing the second tensioning device 2726 to the second connecting seat 2721, so that anti-loosening is achieved. In this embodiment, the first anti-loosening device is a nut, and generally, the nut tightly locks and fixes the second tensioning device 2726 to the second connecting seat; when the tensioning degree of the second elastic member 2725 needs to be adjusted, the nut is unscrewed, the second tensioning device 2726 is rotated to adjust the tensioning degree of the second elastic member 2725 to a desired state, and then the nut is tightened.

Still further, to prevent the second elastic element 2725 from being easily separated from the movable plate 2722 and the second connecting seat 2721, a second mounting portion 2728 is disposed at an end of the second connecting seat 2721 close to the movable plate 2722, a diameter of the second mounting portion 2728 is smaller than a diameter of an end of the second tensioning device 2725 close to the movable plate 2722, and a corresponding mounting protrusion is disposed at a position of the movable plate 2722 corresponding to the second mounting portion 2728. One end of the second elastic member 2725 is sleeved on the second mounting portion 2728, and abuts against one end of the second tensioning device 2726 close to the movable plate, and the other end of the second elastic member 2725 is sleeved on the mounting protrusion.

Still further, in order to make the elastic condition between the movable plate 2722 and the second connecting seat 2721 as uniform as possible along the feeding direction, the second feeding positioning assembly 272 includes at least two second elastic members 2725, and the at least two second elastic members 2725 are sequentially arranged in parallel along the feeding direction. Correspondingly, the number of the second tensioning devices 2726 and the number of the second anti-loosening devices 2727 are two or more, and the two or more second tensioning devices and the two or more second anti-loosening devices correspond to the second elastic pieces 2725 one to one.

To ensure that the movable plate 2722 can only move in a direction parallel to the axis of rotation of the feed wheel 220, and not move in other directions to interfere with the transport of the printed substrate, the feeder module 200 further includes a guide 2729. Specifically, the guiding device 2729 includes a sliding rail 27291 and a sliding block 27292, one of the sliding rail 27291 and the sliding block 27292 is disposed on the second connecting seat 2721, and the other is disposed on the movable plate 2722. In this embodiment, the slide rail 27291 is disposed on the second connecting seat 2721 and extends in a direction parallel to the rotation axis of the feeding wheel 220; correspondingly, the sliding block 27292 is disposed on the movable plate 2722, and the sliding block 27292 is provided with a sliding slot adapted to the sliding rail 27291; the movable plate 2722 is slidably engaged with the slide rail 27291 and the slide block 27292.

Further, in order to prevent the printed substrate passing through the feeding wheel 220 and the pressing wheel 250 from entering the feeding positioning mechanism 270, the end of the printed substrate close to the second feeding positioning component 272 is located between the movable plate 2722 and the second connecting seat 2721, so that the printed substrate cannot be smoothly positioned, the feeding positioning mechanism 270 further includes a pre-guiding device. The pre-guiding device includes a first pre-guiding plate, one end of which is connected to the feeding end of the movable plate (the end of the movable plate close to the feeding wheel), and the other end of which extends to the end far away from the first feeding positioning component 271 and gradually gets away from the center of the movable plate 2722. When the printing substrate enters the feeding positioning mechanism, the end part of the printing substrate firstly abuts against the first pre-guide plate and pushes the first pre-guide plate to one end close to the second connecting seat; in the process of the printing substrate passing through the feeding and positioning mechanism, the printing substrate moves to abut against each guide wheel 2712 under the action of the reverse thrust of the first pre-guide plate and keeps relatively fixed along the direction parallel to the rotating axis of the feeding wheel 220.

Similarly, in order to avoid the situation that the printing substrate passing through the feeding wheel 220 and the pressing wheel 250 enters the feeding positioning mechanism 270, the whole position of the feeding positioning mechanism is higher than the top of the guide wheel or lower than the bottom of the guide wheel, so that the printing substrate cannot be smoothly positioned, the pre-guiding device further comprises a second pre-guiding plate, a third pre-guiding plate, a fourth pre-guiding plate and a fifth pre-guiding plate. The second pre-guiding plate and the third pre-guiding plate are both connected to the movable plate 2722 and are located at one end of the movable plate 2722 close to the first connecting seat 2711. One end of the second pre-guiding plate is connected with the top of the feeding end of the movable plate 2722, and the other end of the second pre-guiding plate extends upwards in an inclined manner and is far away from the center of the movable plate 2722; one end of the third pre-directing plate is connected to the bottom of the feeding end of the movable plate 2722, and the other end thereof extends downward and away from the center of the movable plate 2722.

The second lead screw 2732 extends in a direction parallel to the rotation axis of the feeding wheel 220 and is mounted on the frame 110, and two ends of the second lead screw are respectively supported on the two side plates 111. The second lead screw 2732 includes a third portion 2733 and a fourth portion 2734, wherein the third portion 2733 and the fourth portion 2734 are opposite in rotation. The first connecting seat 2711 is threadedly connected to the third portion 2733 of the second lead screw 2732, and the second connecting seat 2721 is threadedly connected to the fourth portion 2734 of the second lead screw 2732. In this embodiment, the third portion 2733 and the fourth portion 2734 are two independent units, and the third portion 2733 and the fourth portion 2734 are coaxially fixed by a connector to realize coaxial rotation; it is understood that in other embodiments of the present invention, the third portion and the fourth portion may also be two portions with opposite thread directions, which are disposed on the same screw rod structure. In a direction parallel to the extension direction of the second lead screw 2732, the first feeding positioning element 271 and the second feeding positioning element 272 are slidably engaged with the frame 110, in this embodiment, the first connecting seat 2711 and the second connecting seat 2721 are respectively sleeved on the guide shaft 212 to achieve the sliding engagement; it is understood that the first feeding positioning assembly 271 and the second feeding positioning assembly 272 can be slidably engaged with the frame 110 in other manners. The output end of the second motor 2732 is connected to the second lead screw 2732, and is used for driving the second lead screw 2732 to rotate, so that the first feeding positioning component 271 and the second feeding positioning component 272 move in the opposite direction or move in the opposite direction at the same time.

It should be noted that, in this embodiment, the second lead screw 273 and the lead screw 164 are in the same structure, and the second motor 2372 and the first motor 163 are in the same structure, so that the printing apparatus can drive the first positioning plate 151, the second positioning plate 152, the first feeding positioning component 271 and the second feeding positioning component 272 simultaneously through the same motor; when the first lead screw 161 and the second lead screw 273 have the same size, the printing apparatus can synchronously adjust the gap between the first positioning plate 151 and the second positioning plate 152 and the gap between the first feeding positioning assembly 271 and the second feeding positioning assembly 272 by the first lead screw, the second lead screw and the synchronous belt connected with the first lead screw and the second lead screw, and the two gaps are always consistent with the width of the printing substrate, so that the printing apparatus is very convenient.

The operation of the feeder module 200 will be briefly described with reference to the drawings.

When the printing substrate is not pressure-fed between the feeding wheel 220 and the nip wheel 250, the nip wheel 250 abuts against the feeding wheel 220 under the elastic action of the first elastic member 260.

When the feeding wheel 220 feeds, the pressing wheel 250 swings at a certain angle on the common abutting action of the printing substrate and the first elastic member 260, so that the gap between the pressing wheel 250 and the feeding wheel 220 can just allow the printing substrate to pass through. When another printing substrate with a different thickness is replaced, the tension of the first elastic member 260 can be adjusted by the first tensioning device to adapt to the thickness of the replaced printing substrate.

When the printing substrate moves to the feeding positioning mechanism, the height of the printing substrate is kept moderate under the cooperation of the second pre-guide plate, the fourth pre-guide plate and the movable plate 2722, the printing substrate is kept fixed along the direction parallel to the rotation axis of the feeding wheel 220 under the pushing action of the first pre-guide plate and the movable plate 2722, and the printing substrate gradually moves to the printing platform under the pushing action of the feeding wheel 220 and the positioning action of the feeding positioning mechanism to perform a printing process.

Therefore, the feeding module 200 provided by the embodiment can effectively avoid the technical problem that the feeding wheel and the pressing wheel are clamped due to overlarge thickness of the printing substrate, so as to adapt to the printing substrates with different thickness specifications.

Because the base is rigid structure, its effect that bears the printing substrate for the conveyer belt is better, so the design of many conveyer belts parallel arrangement can reduce to a certain extent to print the substrate and bear because printing substrate gravity too big and whole recessed when single conveyer belt to lead to spouting the not good drawback of seal effect. Certainly, the two side edges of the first conveying belt and the second conveying belt perpendicular to the preset direction can also be supported on the top plate of the base, so that the defect that the jet printing effect is poor due to the fact that the first conveying belt and the second conveying belt are concave due to the gravity of the first conveying belt and the second conveying belt is avoided.
