[0038] Figure 1 The following schematically shows the structure of the automatic feeding device according to the embodiment of the present invention at a certain viewing angle. Figure 1 As shown, the utility model proposes an automatic feeding device, including a frame 100, a material bin 200 and a lifting assembly 300; the material bin 200 is located on the frame 100, and the material bin 200 has a receiving groove 101, and a lifting plate 210 is arranged inside the receiving groove 101, and the lifting plate 210 is used to place the material 10, and the lifting plate 210 can be driven to lift the material 10 to a preset position; the fixed end of the lifting assembly 300 is connected to the frame 100, and the output end of the lifting assembly 300 is used to drive the lifting plate 210 to rise and fall.
[0039] Using the automatic feeding device of this technical solution, the lifting assembly 300 drives the lifting plate 210 to rise. When the material 10 rises to a preset position, the industrial robot can grab the material 10, and this cycle repeats. Therefore, the automatic feeding device of this technical solution helps achieve high-precision automated production, effectively saves labor costs, and significantly improves work efficiency.
[0040] Optionally, the material 10 in this embodiment is a casting filter. The industrial robot grabs the casting filter and places it into the sand mold. The industrial robot reduces labor intensity and precisely places the casting filter onto the sand mold, ensuring the consistency of the sand core and improving casting quality. Alternatively, multiple materials 10 can be stacked on the lifting plate 210. When the topmost material 10 reaches a preset position, the industrial robot grabs it.
[0041] Furthermore, the rack 100 includes a tabletop 110 and support columns 120. The support columns 120 are connected to the bottom of the tabletop 110, so that there is a certain distance between the tabletop 110 and the ground, so that some components can be installed on the bottom of the tabletop 110. Optionally, the tabletop 110 is rectangular, and the number of support columns 120 is four, and the four support columns 120 are respectively located at the four corners of the tabletop 110.
[0042] Furthermore, the material bin 200 includes a bottom plate 220, a back plate 230 and at least one pair of side plates 240, the bottom plate 220 is located on the frame 100, and the plurality of side plates 240 are arranged along the first direction ( Figure 1 The back plate 230 is arranged on the bottom plate 220 along the first direction, and the side plate 240 is connected to the side plate 240 on one side of the back plate 230. The bottom plate 220, the back plate 230 and the pair of side plates 240 form a receiving groove 101.
[0043] It can be understood that the back plate 230 and the side plates 240 can be used to limit the position of the material 10, thereby improving the grasping accuracy of the industrial robot. Preferably, each bottom plate 220 is provided with multiple pairs of side plates 240, and a row of materials 10 is placed between each pair of side plates 240, thereby increasing the amount of materials 10 stored in the material bin 200. The side of the side plate 240 away from the back plate 230 is open, and the material 10 is inserted into the receiving groove 101 along the second direction. The receiving groove 101 is in the second direction ( Figure 1 The dimension of the material 10 (in the Y-axis direction) is smaller than the dimension of the material 10 in the second direction, so that the end of the material 10 away from the back plate 230 extends beyond the receiving slot 101, facilitating grasping by the industrial robot. Preferably, a support frame 260 is provided on the side of the back plate 230 facing away from the side plates 240. The support frame 260 is connected to the edge of the back plate 230. The provision of the support frame 260 ensures that the back plate 230 is securely connected to the base plate 220, preventing the back plate 230 from tipping over.
[0044] In this embodiment, the lifting plate 210 includes a connecting plate 410 and multiple lifting plate bodies. The lifting plate bodies are positioned within the receiving slots 101, and the multiple lifting plate bodies are arranged in a one-to-one correspondence with the multiple receiving slots 101. The ends of the lifting plate bodies facing away from the back plate 230 are connected via the connecting plate 410. This structure allows the lifting plate 210 to simultaneously lift the materials 10 in the multiple receiving slots 101 when it rises. Therefore, when the industrial robot is loading materials, it removes the materials 10 from each receiving slot 101 and then activates the lifting assembly 300 to drive the lifting plate 210 upward.
[0045] Furthermore, a plurality of first sockets 221 are provided on the bottom plate 220 along the first direction, a first plug board is provided at the bottom of the side plate 240, and the first plug board and the first socket 221 are plugged in; a plurality of second sockets 231 are provided on the back plate 230 along the first direction, a second socket 231 is provided on the side where the side plate 240 and the back plate 230 are connected, and the second plug board 241 and the second socket 231 are plugged in.
[0046] Optionally, the first and second insertion holes 221, 231 can be arranged in correspondence. When installing the side panel 240, the first insertion plate at the bottom of the side panel 240 is aligned with the first insertion hole 221 on the bottom panel 220, and the second insertion plate 241 on the side is aligned with the second insertion hole 231 on the back panel 230. This structure facilitates the installation of the side panel 240, and allows the appropriate insertion hole to be selected based on the width of the material 10, thereby making the material bin 200 suitable for materials 10 of various widths. Optionally, the first insertion plate is an elongated plate-like structure, and the second insertion plate 241 is an L-shaped plate-like structure, ensuring that the side panel 240 can be plugged into the back panel 230 and the bottom panel 220, respectively, and preventing the side panel 240 from falling during operation.
[0047] Furthermore, a material detection unit 250 is provided on the top of the back plate 230 , and the material detection unit 250 is used to detect whether the material 10 reaches a preset position.
[0048] Specifically, the material detection unit 250 is connected to the control unit by signal. When the material 10 reaches the preset position, the material detection unit 250 can sense the material 10, thereby transmitting a signal to the control unit. The control unit then controls the lifting assembly 300 to stop driving the lifting plate 210 to rise, and controls the industrial robot to grasp the material. Optionally, the material detection unit 250 can be a photoelectric switch or a proximity switch. Optionally, the material detection unit 250 can detect whether the topmost material 10 has reached the preset position. When the material detection unit detects the material 10, the industrial robot grasps the topmost material 10.
[0049] Furthermore, Figure 2 The figure schematically shows the structure of the automatic feeding device according to the embodiment of the present utility model from another perspective. Figure 3 The following schematically shows a partial structural diagram of the automatic feeding device according to the embodiment of the present utility model. Figures 1 to 3 The lifting assembly 300 includes a lifting drive 310 and a screw 320. The lifting drive 310 is connected to the frame 100. The top of the screw 320 passes through the frame 100 and the bottom of the material bin 200 and abuts against the lifting plate 210. The lifting drive 310 is used to drive the screw 320 to rotate.
[0050] It can be understood that the lifting drive 310 drives the lead screw 320 to rotate. When the lead screw 320 rises, the supporting lifting plate 210 rises. When the lead screw 320 falls, the lifting plate 210 falls along with the lead screw 320. Optionally, the lifting drive 310 can be a servo motor.
[0051] Furthermore, the lifting assembly 300 also includes a driving wheel 330, a driven wheel 340 and a synchronous belt 350. The driving wheel 330 and the driven wheel 340 are connected through the synchronous belt 350. The driving wheel 330 is connected to the output end of the lifting drive member 310, and the driven wheel 340 is sleeved on the screw 320 and is spirally connected to the screw 320.
[0052] Specifically, the lifting drive 310 drives the driving wheel 330 to rotate, and the driving wheel 330 drives the synchronous belt 350 to rotate, so that the synchronous belt 350 drives the driven wheel 340 to rotate, and the driven wheel 340 then drives the lead screw 320 to rise or fall. Optionally, a lead screw nut 360 is fixedly connected to the center of the driven wheel 340, and the driven wheel 340 drives the lead screw nut 360 to rotate synchronously. The lead screw 320 is inserted into the lead screw nut 360 and is connected to the lead screw nut 360 by a spiral transmission. Optionally, the driving wheel 330, the driven wheel 340 and the synchronous belt 350 are located above the table 110, and the movable end of the lifting drive 310 is connected to the bottom of the table 110. The movable end of the lifting drive 310 passes through the table 110 and is connected to the driving wheel 330. The lifting assembly 300 adopts this layout method, which can effectively save the overall floor space of the automatic feeding device.
[0053] Furthermore, the automatic feeding device also includes a support assembly 400, which includes a connecting plate 410 and multiple guide rods 420. The bottom of the screw 320 and the bottom of the guide rod 420 are both connected to the connecting plate 410, and the top of the guide rod 420 passes through the bottom of the frame 100 and the material bin 200 and abuts against the lifting plate 210.
[0054] It can be understood that when the lead screw 320 rises, it will drive the connecting plate 410 to rise together, so that the connecting plate 410 supports the guide rod 420 to move upward, and then the guide rod 420 provides support for the lifting plate 210 to ensure that the lifting plate 210 can be lifted and lowered smoothly. Optionally, the connecting plate 410 is rectangular, with a weight-reducing hole in the middle, and four guide members are provided. The four guide rods 420 are respectively connected to the four corners of the connecting plate 410, and the lead screw 320 is connected to the center of the connecting plate 410. In other embodiments, the shape of the connecting plate 410, the position of the lead screw 320, the number and position of the guide rods 420 can be set according to the needs of use, and are not specifically limited here. Optionally, a guide sleeve 430 is connected to the table 110, and the guide rod 420 is inserted into the guide sleeve 430 and can move up and down relative to the guide sleeve 430. By providing the guide sleeve 430, the guide rod 420 can be prevented from tilting, ensuring that the guide rod 420 is vertically ( Figure 1 Z-axis direction) moves smoothly.
[0055] Furthermore, the automatic feeding device also includes a rotating assembly 500, the fixed end of the rotating assembly 500 is connected to the frame 100, the output end of the rotating assembly 500 is connected to the material bin 200, the material bin 200 has multiple receiving slots 101 with openings facing different directions, and the rotating assembly 500 is used to drive the material bin 200 to rotate.
[0056] See also Figure 1 and Figure 2 In this embodiment, the material bin 200 includes two sets of receiving slots 101 with openings facing in opposite directions. After the material 10 in the receiving slots 101 on the side where the lead screw 320 is located is completely grabbed, the material bin 200 can be rotated 180°, so that the receiving slots 101 on the other side are rotated above the lead screw 320, thereby continuing to grab the material 10. The dual-station material bin 200 can effectively improve work efficiency, enable the industrial robot to automatically grab the material 10 without downtime, and enhance the level of automation. In other embodiments, the material bin 200 can include three, four, or five sets of receiving slots 101 with openings facing in different directions. For example, in one embodiment, the material bin 200 includes four sets of receiving slots 101, which are arranged symmetrically about the rotation center of the material bin 200. Therefore, after the material 10 in one set of receiving slots 101 is completely grabbed, the material bin 200 can be rotated 90° to continue grabbing.
[0057] Further, see Figure 2 and Figure 3 The rotating assembly 500 includes a rotating drive member 510 and a connecting seat 520 connected to the bottom of the material bin 200. The fixed end of the rotating drive member 510 is connected to the bottom of the frame 100, and the output end of the rotating drive member 510 passes through the frame 100 and is connected to the connecting seat 520.
[0058] Optionally, the connecting base 520 is connected to the center of the base plate 220. The rotary drive member 510 can drive the connecting base 520 to rotate, thereby driving the material bin 200 to rotate. Optionally, the base plate 220 is connected to the connecting base 520 via bolts. Optionally, the rotary drive member 510 can be a rotary motor.
[0059] Furthermore, a rotation blocking member 600 is provided on the frame 100 , and the rotation blocking member 600 is configured to block the material bin 200 from continuing to rotate after the material bin 200 rotates into position.
[0060] Optionally, the rotation blocking member 600 is a roller lever type blocking cylinder. The roller lever type blocking cylinder mainly includes a fixed seat, a lever, a lifting rod and a roller. The lever is rotatably connected to the fixed seat, the roller is connected to one end of the lever, and the lifting rod is located at the other end of the lever and is used to drive the lever to rotate. When it is necessary to prevent the material bin 200 from rotating, the lifting rod descends, so that the end of the lever away from the roller descends, the roller rises, and the top of the roller is higher than the top plate, thereby preventing the bottom plate 220 from continuing to rotate; when the bottom plate 220 needs to rotate, the lifting rod drives the end of the lever away from the roller to rise, so that the roller descends. When the roller descends to the point where the top of the roller is lower than the bottom plate 220 or is in rolling contact with the bottom of the bottom plate 220, the bottom plate 220 can rotate. The blocking cylinder is a commonly used component in this field, mainly used to stop pallets on the production line, and will not be described in detail here.
[0061] For example, the working process of the automatic feeding device provided in this embodiment is described by taking the material 10 as a cast filter as an example:
[0062] First, appropriate sockets are selected based on the width of the cast filter discs to connect the side panels 240 with the bottom panel 220 and back panel 230 to form a receiving slot 101. Multiple cast filter discs are then stacked in two sets of receiving slots 101. The lifting drive 310 drives the driving wheel 330 to rotate. Driven by the synchronous belt 350, the driven wheel 340 rotates, causing the lead screw 320 to rise, lifting the lifting plate 210 until the material 10 inspection unit detects the cast filter discs. This causes the lifting drive 310 to pause, allowing the industrial robot to grab the topmost cast filter disc. When the material detection unit 250 detects that all the topmost cast filter discs near the industrial robot have been grabbed, the control unit controls the lifting drive 310 to start, raising the lifting plate 210 until the material detection unit 250 can detect the cast filter discs, and this process repeats in sequence. After all the casting filters near the industrial robot have been grabbed, the control unit lowers the roller of the roller lever-type blocking cylinder and activates the rotary drive 510, causing the material bin 200 to rotate 180°. When the material bin 200 has rotated into position, the roller rises and presses against the bottom plate 220 to prevent further rotation of the material bin 200. The industrial robot then continues to grab the casting filters.
[0063] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
