[0032] This section will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present invention, but it should not be understood as a limitation on the scope of protection of the present invention.

[0033] In the present invention, if directions (up, down, left, right, front and back) are described, it is only for the convenience of describing the technical solution of the present invention, and does not indicate or imply that the technical features referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, it cannot be understood as a limitation of the present invention.

[0034] In the present invention, "several" means one or more, "multiple" means more than two, "greater than," "less than," "exceeds," etc. are understood to exclude the number itself; "above," "below," "within," etc. are understood to include the number itself. In the description of the present invention, the use of "first" or "second" is solely for the purpose of distinguishing technical features and is not to be construed as indicating or implying relative importance, implicitly specifying the number of the indicated technical features, or implicitly specifying the order of the indicated technical features.

[0035] In the present invention, unless otherwise expressly defined, terms such as "disposed," "installed," and "connected" should be interpreted broadly. For example, they may refer to direct connection or indirect connection through an intermediate medium; fixed connection or detachable connection or integral molding; mechanical connection or electrical connection or mutual communication; and internal connection between two components or interaction between two components. Those skilled in the art can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0036] At present, the common loading methods for stacked sheet metal parts are manual loading and top-down magnetic suspension separators. Manual loading consumes high manpower costs, and the sheet metal parts separated by the top-down magnetic suspension separator are located at the highest point. When the sheet metal parts in the separator are taken out, the material collection process needs to be stopped, and the machine can only be started after the workers fill the materials from top to bottom, making continuous material collection impossible.

[0037] In order to solve the above technical problems, the present invention provides a feeding device.

[0038] See also Figures 1 to 11 The feeding device includes a discharge bin 100, a blanking mechanism, a magnetic spreader 200, a gripping mechanism 300 and a conveying mechanism 400, wherein the discharge bin 100 has a first feed port and a first blanking port, the blanking mechanism is arranged around the first blanking port, the blanking mechanism is used to send the material plate 001 in the discharge bin 100 out of the first blanking port, the magnetic spreader 200 has a second feed port and a second blanking port 211, the second feed port is aligned with the first blanking port, the gripping mechanism 300 is arranged on the side of the second blanking port 211 discharging material, the gripping mechanism 300 is used to grab the material plate 001 in the magnetic spreader 200, the conveying mechanism 400 is arranged between the second blanking port 211 and the gripping mechanism 300, the conveying mechanism 400 includes a moving device 410 and a driving device 420, the moving device 410 is installed at the power output end of the driving device 420, and the moving device 410 is used to receive the material plate 001 taken out by the gripping mechanism 300.

[0039] During use, the staff puts the material sheet 001 into the discharge bin 100 from the first feeding port, and sends the material sheet 001 in the discharge bin 100 out from the first dropping port through the dropping mechanism, so that the material sheet 001 enters the magnetic spreader 200. The magnetic spreader 200 separates the incoming material sheet 001 by magnetic force, so that two adjacent material sheets 001 are separated. The grabbing mechanism 300 takes out a material sheet 001 from the magnetic spreader 200 each time and places it on the moving device. On 410, the driving device 420 drives the material plate 001 on the moving device 410 to move to another workstation. The magnetic spreader 200 of this feeding device is located between the discharge bin 100 and the gripping mechanism 300, so there is no mutual influence when taking and putting materials. When there are not enough material plates 001 in the discharge bin 100, material plates 001 can be added from the first feed port at any time without stopping the material taking process, so there is no need to stop work, the whole feeding process is more coherent, and the feeding efficiency is higher.

[0040] In some embodiments, the discharge bin 100 includes a first bottom plate 110 and a plurality of guide devices 120 . The first discharge opening is provided on the first bottom plate 110 , and the guide devices 120 are circumferentially spaced apart at the edge of the first discharge opening.

[0041] Specifically, the first blanking port is a through-hole structure provided in the middle of the first bottom plate 110. The shape of the first blanking port is adapted to the outer shape of the material plate 001, and the first blanking port is larger than the material plate 001. The guide device 120 is a cylindrical rod. Each guide device 120 is arranged at intervals around the first blanking port. The guide device 120 extends upward perpendicular to the first bottom plate 110. The guide device 120 is connected to the inner wall of the first blanking port. The area enclosed by each guide device 120 above the first blanking port is used to place the material plate 001. The opening enclosed by the top of each guide device 120 is the first feed port. After the stacked material plates 001 are placed into the discharge bin 100, they are constrained and limited by each guide device 120. This open discharge bin 100 is not only convenient for the staff to add materials, but also has a simple structure and is easy to maintain, and the overall weight is lighter.

[0042] Of course, the guide device 120 may be configured as a plate-shaped structure in addition to being configured as a cylindrical rod structure.

[0043] See also Figure 4 In some embodiments, the blanking mechanism includes a first sensor 500, multiple connectors 600 and multiple clamps 700. The first sensor 500, each connector 600 and each clamp 700 are all installed around the first blanking port. The connector 600 has a receiving block 620, and the clamp 700 has a clamping block 720. The receiving block 620 can be extended and retracted at the edge of the first blanking port, and the clamping block 720 can be extended and retracted at the edge of the first blanking port. Along the direction of blanking, there is a gap between the receiving block 620 and the clamping block 720 to accommodate the thickness of at least one material sheet 001.

[0044] In some other embodiments, there are two connectors 600, both of which are arranged on the first base plate 110, and the two connectors 600 are respectively located on both sides of the first blanking port; there are two clamps 700, both of which are arranged on the first base plate 110, and the two clamps 700 are respectively located on both sides of the first blanking port. The two connectors 600 and the two clamps 700 are arranged alternately in the direction of the first blanking port.

[0045] Of course, the number of the adapter 600 and the clamp 700 can also be two or more, and the specific number can be arranged according to actual needs.

[0046] Specifically, the connector 600 includes a receiving block 620 and a receiving block driving component 610. The receiving block driving component 610 is installed on the first base plate 110, and the receiving block 620 is installed at the power output end of the receiving block driving component 610. The receiving block driving component 610 can drive the receiving block 620 to extend horizontally into the first blanking port or retract horizontally from the first blanking port.

[0047] Before discharging the material from the discharge bin 100, the receiving block 620 is driven by the receiving block driving component 610 to extend into the first material drop opening, thereby forming two support points in the first material drop opening. After the material sheet 001 is placed in the discharge bin 100, the material sheet 001 will be supported by the receiving block 620.

[0048] The clamp 700 includes a clamping block 720 and a clamping block driving component 710. The clamping block driving component 710 is installed on the first base plate 110, and the clamping block 720 is installed at the power output end of the clamping block driving component 710. The clamping block driving component 710 can drive the clamping block 720 to extend horizontally into the first blanking port or retract horizontally from the first blanking port.

[0049] During the working process, first the receiving block 620 of the receiver 600 extends into the first blanking port, and the stacked material sheets 001 are placed on the receiving block 620, and then the clamping device 700 is started so that the clamping block 720 of the clamping device 700 is clamped on the side of the stacked material sheets 001. Since there is a gap between the clamping block 720 and the receiving block 620 along the blanking direction to accommodate the thickness of at least one material sheet 001, when the clamping block 720 clamps the side of the material sheet 001, there will be one or more material sheets 001 between the clamping block 720 and the receiving block 620 that are not clamped by the clamping block 720, but are only restricted to the lower surface of the clamping block 720. Between the upper surface of the receiving block 620, when the receiving block 620 on the connector 600 is retracted from the first blanking port, the material sheet 001 located between the clamping block 720 and the receiving block 620 will fall from the first blanking port, thereby achieving the effect of blanking one or more materials each time. When the next blanking is required, the receiving block 620 is extended to the bottom of the stacked material sheets 001, the clamping block 720 is released, so that the stacked material sheets 001 are replaced on the receiving block 620, and then the clamping block 720 is clamped, so that a material sheet 001 is separated between the clamping block 720 and the receiving block 620, and the material sheet 001 will be blanked after the receiving block 620 is retracted.

[0050] Specifically, the thickness between the lower surface of the clamping block 720 and the upper surface of the receiving block 620 can be set to accommodate only one material sheet 001, so that only one material sheet 001 can be dropped at a time, or the thickness between the lower surface of the clamping block 720 and the upper surface of the receiving block 620 can be set to accommodate multiple material sheets 001, so that multiple material sheets 001 can be dropped at a time.

[0051] The first sensor 500 is a photoelectric sensor used to sense the height of the material plate 001 in the discharge bin 100. The first sensor 500 can be used as a threshold sensor for the number of remaining material plates 001 in the discharge bin 100. When the height is lower than the set threshold, the first sensor 500 is triggered to alarm and remind workers to replenish materials in time.

[0052] In order to ensure that the clamping block 720 can clamp the stacked material sheets 001, in some embodiments, serrations are provided on the clamping surface of the clamping block 720, and the serrations are arranged along the stacking direction of the material sheets 001. After the clamping block 720 clamps the stacked material sheets 001, the edges of the material sheets 001 will be embedded in the serrations of the clamping block 720, thereby improving the clamping effect and preventing the stacked material sheets 001 from falling accidentally.

[0053] The magnetic separator 200 includes a second base plate 210 and multiple magnetic modules 220. The second blanking port 211 is provided on the second base plate 210. One end of the magnetic module 220 is fixed on the second base plate 210, and the other end of the magnetic module 220 is fixed on the first base plate 110. The magnetic modules 220 are arranged at intervals around the second blanking port 211.

[0054] For details, see Figure 5 The magnetic module 220 includes a connecting seat 222 and a magnetic block 221. The magnetic block 221 is a rectangular structure. One end of the magnetic block 221 is fixed to the upper surface of the second base plate 210 through the connecting seat 222, and the other end of the magnetic block 221 is fixed to the lower surface of the first base plate 110. The magnetic modules 220 are arranged around the first blanking port and the second blanking port 211 at intervals. The magnetic field formed by the magnetic blocks 221 between the first blanking port and the second blanking port 211 is used to separate the material plates 001 entering the magnetic separator 200 so that they will not overlap with each other. In addition, the magnetic module 220 can also form a support between the first base plate 110 and the second base plate 210, effectively improving the stability of the overall device.

[0055] The second bottom plate 210 and the first bottom plate 110 are arranged parallel to each other, and the second blanking opening 211 on the second bottom plate 210 is aligned with the first blanking opening on the first bottom plate 110 along the blanking direction.

[0056] It should be noted that, since the magnetic module 220 is connected to the bottom of the first base plate 110 and is arranged around the first blanking opening, the second feed opening in this application coincides with the first blanking opening.

[0057] In some embodiments, one end of the guide device 120 extends to the second blanking opening 211 , and the other end of the guide device 120 extends from the first blanking opening. The guide device 120 is fixedly connected to the magnetic module 220 .

[0058] Specifically, the number of guide devices 120 is the same as the number of magnetic modules 220. A guide device 120 is fixed on the side of each magnetic module 220. One end of the guide device 120 extends downward to be connected to the inner wall of the second blanking port 211, and the other end of the guide device 120 extends upward through the inner wall of the first blanking port and extends from above the first blanking plate 001. In this way, the material plate 001 is always constrained by the same guide device 120 during the movement between the discharge bin 100, the first blanking port, the magnetic spreader 200 and the second blanking port 211, which effectively ensures the stability of the material plate 001 during the movement.

[0059] In some other embodiments, one end of the magnetic module 220 is detachably connected to the first base plate 110, and the other end of the magnetic module 220 is connected to the second base plate 210 through the connecting seat 222. The connecting seat 222 is provided with an adjustment hole, and a fastener is passed through the adjustment hole to fix the connecting seat 222 on the second base plate 210. When the position of the magnetic module 220 needs to be adjusted, the bolts connecting the magnetic module 220 and the first base plate 110 are loosened, the fasteners connecting the connecting seat 222 and the second base plate 210 are loosened, and then the connecting seat 222 is slid along the adjustment hole. After adjustment is in place, the fasteners connecting the second base plate 210 and the connecting seat 222 and the bolts connecting the magnetic module 220 and the first base plate 110 are tightened. In this way, the position of the guide device 120 can be adjusted by adjusting the relative position of the magnetic module 220, thereby realizing the size adjustment of the discharge bin 100, the first blanking port, the magnetic spreader 200 and the second blanking port 211 to adapt to different types of material plates 001.

[0060] Of course, the connection method between the connecting seat 222 and the second base plate 210 can also be set to a magnetic connection method. Specifically, the connecting seat 222 is set to a magnetic structure, and the connecting seat 222 is directly adsorbed on the second base plate 210. When the position of the magnetic module 220 needs to be adjusted, the magnetism of the connecting seat 222 is disconnected for adjustment. After the adjustment is in place, the magnetic force of the connecting seat 222 is restored to make it adsorbed and connected to the second base plate 210.

[0061] See also Figure 10 In some other embodiments, the guide device 120 is installed on the magnetic module 220 through the connecting block 223 , and the connecting block 223 can be adjusted horizontally relative to the magnetic module 220 .

[0062] Specifically, a horizontally extending strip hole is provided on the connecting block 223, and a fastening bolt is passed through the strip hole to fix the connecting block 223 on the magnetic module 220. The guide device 120 is fixed to one end of the connecting block 223. When the position of the guide device 120 needs to be adjusted, the fastening bolt in the strip hole is loosened, and the connecting block 223 is slid along the strip hole to adjust the relative position of the guide device 120. After the adjustment is in place, the fastening bolt can be tightened.

[0063] See also Figure 8 、 Figure 9 In some embodiments, the present application further includes a bracket 800, a slide rail 830 is provided on the bracket 800, the mobile device 410 is slidably installed on the slide rail 830, the driving device 420 is installed on the bracket 800, and a transmission rod is installed at the power output end of the driving device 420, and the transmission rod is connected to the mobile device 410.

[0064] Specifically, the bracket 800 includes a pillar 810 and a panel 820. The pillar 810 is vertically arranged at the four corners of the panel 820 to support the panel 820. Two parallel guide rails are provided on the panel 820. A slider is installed on the moving device 410, and the slider is slidably assembled on the slide rail 830. The driving device 420 is installed on the panel 820. One end of the transmission rod is connected to the power output end of the driving device 420, and the other end of the transmission rod is connected to the moving device 410. The driving device 420 can drive the transmission rod to extend and retract, so that the transmission rod drives the moving device 410 to slide on the slide rail 830.

[0065] In some embodiments, the material grabbing mechanism 300 is mounted on the bracket 800 , and a through hole 411 for avoiding the material grabbing mechanism 300 is provided in the middle of the moving device 410 .

[0066] Specifically, the material grabbing mechanism 300 includes a lifting device and a material grabbing suction cup. The material grabbing suction cup is installed at the lifting movable end of the lifting device. The lifting device first drives the material grabbing suction cup to rise through the through hole 411 and enter the magnetic spreader 200, so that the material grabbing suction cup absorbs the material plate 001. Then the lifting device drives the material grabbing suction cup to descend and brings the material plate 001 to the moving device 410, and then the material grabbing suction cup releases the material plate 001.

[0067] In order to ensure that the material plate 001 grabbed by the grabbing mechanism 300 can be placed stably on the moving device 410, in some embodiments, a second sensor 412 and multiple receiving seats 413 are provided on the moving device 410, and the second sensor 412 and each receiving seat 413 are distributed around the through hole 411, and the second sensor 412 is connected to the driving device 420.

[0068] Specifically, the receiving seats 413 are distributed around the through hole 411 according to the recessed positions of the material sheet 001. Some of the receiving seats 413 are provided with pins corresponding to the positioning holes on the material sheet 001. After the grabbing mechanism 300 grabs the material sheet 001, the recessed positions on the material sheet 001 will correspond to the receiving seats 413, and the positioning holes on the material sheet 001 will be inserted into the pins on the corresponding receiving seats 413, so that the material sheet 001 is placed stably on the moving device 410 and will not fall off during the movement.

[0069] In addition, a guide plate 414 is vertically provided on the mobile device 410. The guide plate 414 is used to stick to the edge of the material sheet 001. When the grabbing mechanism 300 pulls the material sheet 001 to move downward, the edge of the material sheet 001 will drop along the guide plate 414. The guide plate 414 plays a vertical guiding role, ensuring that the guide plate 414 can accurately drop vertically to the receiving seat 413 of the mobile device 410.

[0070] When the second sensor 412 senses that the material sheet 001 is stably attached to the receiving seat 413, the driving device 420 will drive the moving device 410 to retract to move the material sheet 001 to the next material-picking position. When the material sheet 001 is taken away and the second sensor 412 no longer senses the material sheet 001, the driving device 420 drives the moving device 410 to extend, so that the moving device 410 returns to its initial state.

[0071] The second sensor 412 may be a photoelectric sensor device.

[0072] See also Figure 7 、 Figure 11 When the shape of the material sheet 001 is relatively irregular and the weight distribution is uneven, when the material sheet 001 freely falls from the discharge bin 100 into the magnetic spreader 200, it is easy to overturn, twist and other problems. In order to solve this technical problem, in some embodiments, a correction mechanism 900 is provided between the first bottom plate 110 and the second bottom plate 210. The correction mechanism 900 includes a mounting block 910 and a correction rod 920. The correction rod 920 is detachably connected to the first bottom plate 110 and / or the second bottom plate 210 through the mounting block 910. The correction rod 920 is located at the edge of the second blanking port 211, and the correction rod 920 is provided with serrations 921.

[0073] Specifically, the correction mechanism 900 is set at a position where the material plate 001 is prone to overturning or twisting. Generally, the correction mechanism 900 is set between two adjacent magnetic modules 220 at the position where overturning or twisting is prone to occur. The mounting block 910 can be installed on the first base plate 110 to fix the correction rod 920, or the mounting block 910 can be installed on the second base plate 210 to fix the correction rod 920. The mounting block 910 can also be fixed on both the first base plate 110 and the second base plate 210 to fix the correction rod 920. The correction rod 920 is provided with a serration 921 on the side facing the second blanking port 211, or the entire correction rod 920 can be set to a structure with serrations 921.

[0074] When the material sheet 001 enters the magnetic spreader 200 and has problems such as overturning or twisting, the material sheet 001 will sink into the serrations 921 of the correction rod 920. The overturned or twisted point will first contact the serrations 921. The serrations 921 will act as a support and buffer, allowing the overturned or twisted point to change its force state and restore to a horizontal state, thereby being evenly affected by the magnetic field force.

[0075] In some other embodiments, a long hole 911 is provided on the mounting block 910, and a bolt is passed through the long hole 911 to fix the mounting block 910 on the first base plate 110. When the position of the correction mechanism 900 needs to be adjusted, the bolt in the long hole 911 can be loosened, and the mounting block 910 can be slid along the long hole 911. After the position is adjusted, the bolt can be tightened.

[0076] Of course, the present application is not limited to the above-mentioned embodiments. Those skilled in the art may make equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of the present application.
