DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0023] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0024] like Figure 1-5 , which is a structural diagram of a material loader provided by an embodiment of the present invention, the material loader includes a mounting plate 1101, a power member 15, a transmission structure and a gripping mechanism 14;

[0025] The power member 15 is disposed on the mounting plate 1101 and is used to drive the grasping mechanism 14 to move and rotate at the same time through the transmission structure;

[0026] The transmission structure is arranged on the mounting plate 1101, and includes a driving assembly 12 and a rotating assembly 13 connected in sequence, and is used to convert the rotational motion of the power member 15 into the movement and rotation of the grabbing mechanism 14;

[0027] The grabbing mechanism 14 is disposed on the rotating assembly 13 and moves along with the rotating assembly 13 to grab or adsorb materials.

[0028] In the embodiment of the present invention, the entire loader can be arranged on a base 11 , and the base 11 includes a mounting plate 1101 , a driving seat 1102 and a cover plate 1103 .

[0029] In the embodiment of the present invention, the power member 15 can be connected to the mounting plate 1101 by screws or other common methods; the power member 15 can be implemented by a motor 1501, and can also include a mechanical transmission part 1502 and an output shaft 1503. In addition, other single elements or combinations of multiple elements that can generate rotational motion can also be used, which is not specifically limited in the embodiment of the present invention.

[0030] In the embodiment of the present invention, the transmission structure can be implemented by a combination of one or more transmission parts such as an eccentric wheel 1201, a gear, a rod group, a transmission belt, etc. The transmission structure in the embodiment of the present invention is used to convert the rotational motion of the power member 15 into the movement and rotation of the grasping mechanism 14. It should be understood that the movement here includes swinging, translation, etc., and the rotation refers to the rotational motion of the grasping mechanism 14 around a certain axis. The rotational motion here is not the same as the aforementioned swinging motion.

[0031] In the embodiment of the present invention, the gripping mechanism 14 is used to grip or adsorb materials. The gripping mechanism 14 can grip the materials by clamping, or can absorb the materials by adsorption using the suction cup 1403. When the clamping method is adopted, the gripping mechanism 14 should be equipped with a corresponding gripping drive device; when the adsorption method is adopted, a corresponding suction device should be equipped to generate negative pressure.

[0032] The loading machine provided in the embodiment of the present invention can realize the swing and rotation of the grasping mechanism 14 by using a motor 1501 through the arrangement of a transmission mechanism, so as to realize the grasping of materials and place them in the processing position after adjusting the angle of the materials. It is different from the scheme of setting multiple driving elements in the joint structure of the traditional robot arm, and has a simple structure, ingenious design and easy implementation; it can realize automatic loading in cooperation with the sheet material feeding hopper.

[0033] like Figure 5 As shown, in one embodiment of the present invention, the driving assembly 12 includes a rotating component and a swinging component, and the rotating component includes an eccentric wheel 1201;

[0034] The eccentric wheel 1201 is arranged on the output shaft 1503 of the power member 15;

[0035] The rotating component is connected to the swing component through a connecting rod group 1203, and the connecting rod group 1203 is used to drive the swing component to swing. The connecting rod group 1203 includes a pin shaft 12031, a joint bearing 12032 and a connecting rod 12033; the connecting rod 12033 is rotationally connected to the eccentric wheel 1201 through the pin shaft 12031, and the connecting rod 12033 is arranged into two sections that can move relative to each other through the joint bearing 12032.

[0036] In an embodiment of the present invention, the structure of the eccentric wheel 1201 itself can be axisymmetric. The eccentricity mainly refers to the fact that the connection position with the connecting rod group 1203 does not coincide with the wheel center of the wheel, and does not mean that the eccentric wheel 1201 itself is a non-axisymmetric structure. Of course, the eccentric wheel 1201 adopts a non-axisymmetric structure to achieve the technical effect of the present invention. This is an optional specific implementation method, and the example of the present invention does not make specific limitations on this.

[0037] In the embodiment of the present invention, the connecting rod group 1203 is used to drive the swinging part to swing, and the connecting rod group 1203 is driven by the eccentric wheel 1201. The connecting rod group 1203 includes a pin shaft 12031, a joint bearing 12032 and a connecting rod 12033. The connecting rod 12033 is rotatably connected to the eccentric wheel 1201 through the pin shaft 12031. The joint bearing 12032 is arranged on the connecting rod 12033. The arrangement of the joint bearing 12032 allows the two connecting ends of the connecting rod to rotate relative to each other, so as to be suitable for different connection forms.

[0038] The loading machine provided in the embodiment of the present invention is used to drive the swinging component by setting an eccentric wheel 1201 and a connecting rod group 1203. This method can adjust the swinging range of the swinging component by adjusting the eccentric distance and the rotation angle of the eccentric wheel 1201. The structure is simple and easy to implement.

[0039] like Figure 5 As shown, in one embodiment of the present invention, the swing component includes a support shaft 1202 and a swing rod 1204;

[0040] The support shaft 1202 is disposed on the mounting plate 1101;

[0041] One end of the rocker arm 1204 is rotatably connected to the support shaft 1202, and a first connecting hole is provided on the rocker arm 1204, through which the connecting rod 12033 is rotatably connected to the rocker arm 1204; a second connecting hole is provided on the rocker arm 1204, and the second connecting hole is used to connect to the rotating component 13.

[0042] In the embodiment of the present invention, driven by the connecting rod 12033, the swing rod 1204 can swing around the support shaft 1202 to drive the rotating assembly 13 to swing. Optionally, bearings can be provided at the connection between the swing component and the support shaft 1202, the connecting rod 12033 and the rotating assembly 13, and the bearings are provided to facilitate rotation.

[0043] The swing arm 1204 provided in the loading machine provided in the embodiment of the present invention can swing around the support shaft 1202 under the drive of the connecting rod 12033, thereby driving the rotating component 13 to swing, and this swinging motion mainly corresponds to the movement of the grabbing member from the material picking position to the material unloading position.

[0044] like Figure 5 As shown, in one embodiment of the present invention, the rotating assembly 13 includes a slide slot 1301, a follower 1302, a flip connecting rod 1303 and a flip shaft 1304;

[0045] The slide groove 1301 is arranged on the mounting plate 1101, and the slide groove 1301 is in a straight line shape;

[0046] The follower 1302 is slidably connected to the slide slot 1301 and is rotationally connected to the flip connecting rod 1303;

[0047] The flip connecting rod 1303 is rotationally connected to the flip shaft 1304, and the rotation axis of the follower 1302 and the rotation axis of the flip shaft 1304 do not overlap;

[0048] The flip shaft 1304 is rotatably connected to the swing rod 1204 , and the grabbing mechanism 14 is disposed on the flip shaft 1304 .

[0049] In the embodiment of the present invention, the slide groove 1301 is linear, and the follower 1302 can slide along the slide groove 1301. At the same time, the follower 1302 is rotatably connected with the flip connecting rod 1303. The rotation axis of the follower 1302 and the rotation axis of the flip shaft 1304 do not overlap. Here, the rotation axis of the follower 1302 refers to the rotation axis about which the flip connecting rod 1303 rotates around the follower 1302. The grasping mechanism 14 is arranged on the flip shaft 1304, and can rotate while moving with the flip shaft 1304.

[0050] The loading machine provided in the embodiment of the present invention can drive the grabbing mechanism 14 to move and rotate by setting a rotating component 13. The purpose of the movement is to move the grabbed material from the material picking position to the material feeding position, and the purpose of the rotation is to adjust the direction of the material during the movement. In the embodiment of the present invention, the two simultaneous movements of movement and rotation are driven by the same power part 15, reducing the use of driving elements.

[0051] like Figure 5As shown, in one embodiment of the present invention, the feeder further includes a sensor assembly 16, and the sensor assembly 16 includes a slot switch and a sensor sheet 1603;

[0052] The slot switches are provided with two and are located on the mounting plate 1101 , and the two slot switches are arranged along the circumference of the eccentric wheel 1201 ;

[0053] The induction sheet 1603 is disposed on the eccentric wheel 1201 , and when the eccentric wheel 1201 rotates, the induction sheet 1603 can trigger the slot switch to generate an electrical signal.

[0054] In an embodiment of the present invention, two slot-shaped switches are arranged circumferentially with the rotation center of the eccentric wheel 1201 as the center of the circle, and the angle between the two slot-shaped switches can be adjusted, so that the rotation angle of the eccentric wheel 1201 in each motion cycle can be adjusted. The slot-shaped switches may include slot-shaped switch A1601 and slot-shaped switch B1602. An inductor sheet is provided on the eccentric wheel 1201. When the eccentric wheel 1201 rotates and drives the inductor sheet to move to the position of the slot-shaped switch, the slot-shaped switch may be triggered to generate an electrical signal, which may be used for controlling the power part 12, such as for start-stop control, speed control or reversing control of the power part 15. Of course, it may also be used for controlling the grasping mechanism 14, which is an optional specific implementation method, and the embodiment of the present invention does not specifically limit this.

[0055] The feeder provided in the embodiment of the present invention can be used to control the power member 15 and / or the gripping mechanism 14 by setting a slot-shaped switch. The implementation method is simple, there is no need to improve the setting of the transmission structure, and the cost is low.

[0056] In one embodiment of the present invention, a three-section adjustment structure is provided on the connecting rod 12033, wherein the front and rear sections are threaded sleeves with opposite rotation directions, and the middle section is a threaded rod with threads of opposite rotation directions at both ends. The two ends of the middle section are respectively connected to the front and rear sections, and the length of the connecting rod 12033 can be adjusted by rotating the middle section.

[0057] In the embodiment of the present invention, the connecting rod 12033 is arranged into two rotatable sections through the joint bearing 12032, and the three-section adjustment structure can be arranged on any one of the two rotatable sections. The three-section adjustment structure includes a threaded sleeve and a threaded rod, and the threads of the two threaded sleeves are in opposite directions. The threaded rod is provided with threads in opposite directions that cooperate with the two threaded sleeves. By rotating the threaded rod, the two threaded sleeves can be moved closer or farther away, thereby adjusting the length of the connecting rod 12033.

[0058] The loading machine provided in the embodiment of the present invention can be used to adjust the length of the connecting rod 12033 by setting a three-stage adjustment structure on the connecting rod 12033. When the length of the connecting rod 12033 is different, the swing range of the rocker arm 1204 is different at the same rotation angle of the eccentric wheel 1201, so that the swing range of the grasping mechanism 14 can be finally adjusted, thereby improving applicability.

[0059] In one embodiment of the present invention, the first connecting hole is a strip-shaped through hole, the strip-shaped through hole is opened along the length direction of the swing rod 1204, and the position of the connecting rod in the strip-shaped through hole is adjustable.

[0060] In the embodiment of the present invention, the connecting rod 12033 is rotatably connected to the swing rod 1204 through the first connecting hole, and a connecting piece can be provided at the connection. The connecting piece is divided into two ends, one end is connected to the first connecting hole through a screw and a nut, and the other end is connected to the connecting rod 12033 through a bearing. The bearing can be provided on the connecting rod 12033 or on the connecting piece, which is an optional specific implementation. When the relative position of the connecting rod 12033 and the swing rod 1204 is to be adjusted, the position of the connecting piece relative to the first connecting hole is adjusted by loosening the nut, and then the nut is tightened to fix it.

[0061] The loading machine provided by the embodiment of the present invention can conveniently adjust the relative positions of the connecting rod 12033 and the rocker arm 1204 by setting a bar through hole at the connection between the connecting rod 12033 and the rocker arm 1204, thereby adjusting the swing range of the swing component without changing the rotation range of the eccentric wheel 1201, and finally realizing the adjustment of the swing range of the grasping mechanism 14. It is convenient to implement and easy to adjust, which can improve the applicability of the loading machine.

[0062] like Figure 5 As shown, in one embodiment of the present invention, the loader also includes a cover plate 1103, which is shell-shaped and provided with an opening, and the shape of the opening matches the mounting plate 1101; an arc-shaped through groove is provided on the cover plate 1103, and the flip shaft 1304 is connected to the grabbing mechanism 14 after passing through the through groove.

[0063] In the embodiment of the present invention, the cover plate 1103 is configured in a shell shape, and the cover plate 1103 and the mounting plate 1101 can be fixed by screw connection, welding, etc. An arc-shaped through slot is provided on the cover plate 1103, and the flip shaft 1304 passes through the through slot and is connected to the grabbing mechanism 14.

[0064] The loading machine provided in the embodiment of the present invention is also provided with a cover plate 1103, and an arc-shaped groove is provided on the cover plate 1103. Through the setting of the arc-shaped groove, the flip shaft 1304 can move along the arc-shaped groove, which is actually swinging. At the same time, the flip shaft 1304 itself is still rotating, and the direction of the material can be adjusted while moving the material.

[0065] like Figure 5 As shown, in one embodiment of the present invention, the gripping mechanism 14 includes a fixing seat 1401, a suction cup 1403 seat and a suction cup 1403;

[0066] The fixing seat 1401 is disposed on the rotating assembly 13, and the relative angle between the fixing seat 1401 and the rotating assembly 13 is adjustable;

[0067] The suction cup 1403 seat is arranged on the fixing seat 1401 and is used for installing the suction cup 1403;

[0068] At least one suction cup 1403 is provided, and the suction cup 1403 is connected to an air suction or exhaust device through a pipeline.

[0069] In the embodiment of the present invention, the suction cup 1403 is a conventional component in the field, and the embodiment of the present invention will not specifically describe its installation and use methods. A plurality of suction cups 1403 can be provided, and the plurality of suction cups 1403 are preferably provided on the same plane, and can be used to adsorb sheets, plates, etc. In addition, as another optional specific implementation method, the grasping mechanism 14 can also grasp the material in a clamping manner, and the grasping mechanism 14 should be equipped with corresponding driving elements. In the embodiment of the present invention, the grasping mechanism 14 is replaceable to suit different usage scenarios, and the specific grasping mechanism 14 adopted has no substantial impact on the present invention.

[0070] The feeder provided in the embodiment of the present invention can be used for adsorbing sheets and plates by providing a gripping mechanism 14 of the suction cup 1403 type, and has a simple structure and is easy to implement.

[0071] like Figure 6 As shown, in one embodiment of the present invention, a sheet material feeding system is also provided, and the sheet material feeding system comprises:

[0072] A sheet material feeding bin 4, the sheet material feeding bin 4 is used to provide sheets to the feeder 1;

[0073] As described in any embodiment of the present invention, the loading machine 1 is used to grab the sheet from the sheet supply bin 4 and transport it to the next station; and

[0074] The control device 3 is electrically connected to the sheet material feeding bin 4 and the loader 1 respectively, and is used for controlling the operation of the sheet material feeding bin 4 and the loader 1 and matching the actions of the two.

[0075] In the embodiment of the present invention, the sheet material feeding system may further include a vacuum system 2, which may be used to generate the adsorption force of the gripping device. The control device 3 may include a display screen, an operation panel, buttons and other structures, which are conventional settings of the control device and are not specifically limited in the embodiment of the present invention.

[0076] The sheet feeding system provided by the present invention can transport the sheet from the exit position of the sheet feeding silo to the loading position of the next workstation through the cooperation between the sheet feeding silo and the loader. While realizing the sheet transportation, the direction of the sheet can be automatically flipped. The two composite actions are realized by one driving motor, which is beneficial to the realization of production automation.

[0077] like Figure 7 As shown, in one embodiment of the present invention, the sheet material feeding bin includes a conveying assembly 41, and the conveying assembly 41 is used to provide power for the upright sheets to be conveyed forward; the conveying assembly 41 includes a fixed plate 4102 and a plurality of rollers 4106 disposed on the fixed plate 4102;

[0078] The roller 4106 is provided with a conveyor belt 4104, and the conveyor belt 4104 is driven by a motor 4107;

[0079] The conveying portion of the conveyor belt 4104 includes a horizontal section and an inclined section, and the anti-falling block 4301 is at least in contact with the horizontal section;

[0080] The conveying assembly 41 also includes a support plate 4101 and a side baffle 4201;

[0081] The support plate 4101 is disposed on the fixed plate 4102. The shape of the support plate 4101 matches the shape of the conveying portion of the conveyor belt 4104. The support plate 4101 includes a horizontal section and an inclined section. The conveying portion of the conveyor belt 4104 is higher than the surface of the support plate 4101.

[0082] There are two side baffles 4201, which are arranged on both sides of the support plate 4101. The support plate 4101 and the side baffles 4201 on both sides form a conveying trough, and the conveying part of the conveyor belt 4104 is located at the bottom of the conveying trough.

[0083] In the embodiment of the present invention, the conveying assembly 41 is used to provide power for the conveying of the sheet, and includes a fixed plate 4102 and a roller 4106 arranged on the fixed plate 4102, the roller 4106 is installed on the fixed plate 4102 through a roller shaft 4103, and a conveyor belt 4104 is sleeved on the roller 4103. In the embodiment of the present invention, the roller 4106 is used to guide the conveyor belt 4104, and the motor 4107 drives the conveyor belt 4104 to rotate through the active roller 4108, and the motor 4107 is installed on the fixed plate 4102 through the motor seat 4105. In the embodiment of the present invention, as an optional specific implementation method, the fixed plate 4102 is placed upright, and its two side surfaces face the horizontal direction, and the conveyor belt 4104 and the roller 4106 are arranged on one of the side surfaces; it can be understood that the side surfaces of the fixed plate 4102 here refer to the two surfaces with larger areas on the fixed plate 4102.

[0084] In the embodiment of the present invention, the conveying portion of the conveyor belt 4104 refers to the portion of the conveyor belt 4104 that can contact the sheet or the anti-reversal block 4301. The conveying portion includes a horizontal section and an inclined section. The horizontal here is determined by the sheet feeding bin in a normal installation state. The horizontal here is not an absolute horizontal, but only relative to the inclination. Preferably, the inclination in the embodiment of the present invention refers to each downward inclination. In the embodiment of the present invention, the anti-reversal block 4301 can only abut the horizontal section of the conveyor belt 4104, or it can abut the horizontal section and the inclined section successively during the movement. It should be understood that since the conveyor belt 4104 rotates during operation, the horizontal section and the inclined section here do not refer to a specific position on the conveyor belt 4104, but refer to the part after any part of the conveyor belt 4104 moves to the horizontal area or the inclined area. The horizontal area and the inclined area here are respectively the part between at least two rollers 4106 arranged horizontally and at least two rollers 4106 arranged obliquely. When any portion of the conveyor belt 4104 moves between these rollers 4106, that portion of the conveyor belt 4104 becomes horizontal or inclined.

[0085] In the embodiment of the present invention, the support plate 4101 is arranged through the conveyor belt 4104, the conveying part of the conveyor belt 4104 is located on the upper surface of the support plate 4101, and the side baffles 4201 are arranged on both sides of the support plate 4101, and the side baffles 4201 and the support plate 4101 form a U-shaped conveying trough with an upper opening. Through this arrangement, the sheet can stay on the conveyor belt 4104 stably.

[0086] In the sheet material feeding system provided by the embodiment of the present invention, the conveying part of the sheet material feeding silo conveyor belt 4104 includes a horizontal section and an inclined section. After the horizontal section, the conveying of the inclined section can utilize the natural falling of the sheet material toward the inclined section to present a certain inclined state.
