[0001] The present invention mainly relates to the technical field of sheet metal grinding and processing, and particularly relates to an automatic feeding device for a manipulator grinding equipment. Background Art

[0002] In the field of sheet metal grinding and processing, the traditional feeding method mainly relies on manual operation, which has problems such as low efficiency, high labor intensity, and easy generation of safety hazards. With the development of automation technology, some enterprises use robotic arms with suction cups to achieve automatic feeding. However, such a solution requires a separate feeding robotic arm, and another robotic arm is already needed for the grinding process itself, resulting in a several-fold increase in equipment costs. In addition, the drive unit of the robotic arm is complex and the maintenance cost is high, making it cost-ineffective in simple loading and unloading scenarios. Based on the above problems, there is an urgent need for an automatic feeding device that can be directly integrated into the grinding manipulator to achieve low-cost and high-precision feeding functions by simplifying the transmission structure and reducing independent drive units.

[0021] Referring to the attached Figure 1-6 , an automatic feeding device for a manipulator grinding device, includes a base 1. Two symmetrically arranged first limit columns 2 are symmetrically provided on the top of the base 1. A storage bin is formed between the two first limit columns 2. A stack of plates 3 is provided vertically in the storage bin; On one side of the storage bin, a linear drive module 4 is provided. The output end of the linear drive module 4 is connected to a pushing plate 5 and is used to drive the pushing plate 5 to perform intermittent reciprocating linear motion in the horizontal direction, so as to push the sheet material 3 at the bottom layer of the storage bin to the processing station on the other side of the storage bin. The processing station corresponds and cooperates with the processing area of the automatic grinding device 6 arranged on the base 1.

[0022] In this embodiment, after the sheet materials 3 to be ground are vertically stacked in the storage bin formed between the two first limiting columns 2, the linear drive module 4 drives the pushing plate 5 to perform intermittent reciprocating linear motion in the horizontal direction, so that the sheet material 3 at the bottom layer of the storage bin can be pushed to the processing station on the other side of the storage bin. And during the intermittent time, it can cooperate with the automatic grinding device 6 for grinding. By reciprocating and circulating, automatic continuous feeding can be carried out for the processing station. The overall mechanism is simple, and low-cost and high-precision feeding is achieved.

[0023] At the bottom of the first limiting column 2, a first sliding block 201 is fixed. The first sliding block 201 is slidably connected to a first sliding groove 101 longitudinally opened at the top of the base 1. A first limiting hole 202 is vertically penetrated through the surface of the first sliding block 201, and a first positioning bolt 7 is fitted and installed in the first limiting hole 202.

[0024] In this embodiment, after the first sliding block 201 slides in the first sliding groove 101, the first limiting column 2 keeps synchronous displacement. The first positioning bolt 7 in the first limiting hole 202 can be tightened so that its end abuts against the bottom of the first sliding groove 101, thereby locking the first sliding block 201 and the first limiting column 2 at the current position. Similarly, it can be locked at other positions, so that the distance between the two first limiting columns 2 can be adjusted to limit the sheet materials 3 of different width specifications.

[0025] On one side of the vertically stacked sheet materials 3 close to the linear drive module 4, two symmetrically distributed second limiting columns 8 are attached. The bottom ends of the second limiting columns 8 coincide with the upper surface of the sheet material 3 at the bottom layer of the storage bin.

[0026] In this embodiment, the second limiting columns 8 are used to limit the stacked sheet materials 3 to prevent the stacked sheet materials 3 from collapsing when the pushing plate 5 is feeding. There is a gap with the same thickness as the sheet material 3 between the bottom end of the second limiting column 8 and the top of the base 1 to ensure that the sheet material 3 can pass through.

[0027] On the base 1, a first fixing bracket 10 is provided. The two second limiting columns 8 are slidably connected to the first fixing bracket 10 vertically, and the tops of both are fixedly connected to a connecting plate 9. The connecting plate 9 is threadedly connected with a vertically extending lead screw 11, and the lead screw 11 is rotatably installed on the first fixing bracket 10.

[0028] In this embodiment, after rotating the lead screw 11 and in cooperation with the threaded connection between the lead screw 11 and the connecting plate 9, the second limit column 8 can be driven to slide relative to the first fixing bracket 10, so that the height of the second limit column 8 can be adjusted to accommodate plates 3 of different thicknesses.

[0029] The linear drive module 4 includes a connecting plate 401. One end of the connecting plate 401 is fixed to the end of the pusher plate 5, and the other end is provided with two symmetrically arranged guide rods 402, which are horizontally slidably connected to a second fixing bracket 403 arranged on the top of the base 1. The linear drive module 4 further includes a servo motor 404 installed on the base 1. The output end of the servo motor 404 is fixed with a turntable 405. An eccentric drive pin 406 is provided at one end of the turntable 405 away from the servo motor 404. The drive pin 406 is slidably installed in a composite track groove opened on the connecting plate 401. The composite track groove includes a continuously connected arc-shaped guiding portion 407 and a vertical guiding portion 408, and the vertical guiding portion 408 is communicated with both ends of the arc-shaped guiding portion 407.

[0030] In this embodiment, after the servo motor 404 is started, the turntable 405 rotates synchronously. The eccentric drive pin 406 thereon will move within the composite track groove. In cooperation with the horizontal sliding between the second fixing bracket 403 and the guide rod 402, when the drive pin 406 slides into the two vertical guiding portions 408, the pusher plate 5 can be driven to perform a linear reciprocating motion. When the drive pin 406 slides into the arc-shaped guiding portion 407, the movement track of the drive pin 406 is the same as that of the arc-shaped guiding portion 407, so that the pusher plate 5 will not be driven to move, thereby realizing the intermittent reciprocating linear motion of the pusher plate 5.

[0031] Extension rods 12 are symmetrically fixed on both sides of the pusher plate 5. A slide rail 13 inclined towards the center of the plate 3 is fixed at the end of each extension rod 12. A second slider 14 is slidably fitted in the slide rail 13. The second slider 14 is fixedly connected to the end of the first longitudinal plate 151 of the special-shaped plate 15. The special-shaped plate 15 is integrally formed by a first longitudinal plate 151 and a second longitudinal plate 152 arranged in parallel and a transverse plate 153 connecting the two. A third slider 16 slidably fitted with the second chute 102 on the top of the base 1 is fixed at the bottom of the first longitudinal plate 151. The free end of the second longitudinal plate 152 extends to both sides of the processing area and is provided with corresponding limiting plates 17.

[0032] In this embodiment, when the linear drive module 4 drives the pusher plate 5 to push the sheet 3 at the bottom layer of the storage bin to the processing station, the slide rail 13 moves in a synchronous straight line. The second slider 14 will slide within the slide rail 13, thereby driving the third slider 16 to slide within the second chute 102, enabling the entire special-shaped plate 15 to move towards the outside of the sheet 3. Another special-shaped plate 15 moves relatively. The two limit plates 17 will move relatively towards the outside of the sheet 3. Similarly, when the linear drive module 4 drives the pusher plate 5 to move in the reverse direction, the two limit plates 17 will move towards the inside of the sheet 3. That is, when the automatic grinding device 6 grinds the sheet 3, the two limit plates 17 will clamp and position the sheet 3. When the pusher plate 5 feeds the sheet 3 to the processing station, the two limit plates 17 will release the currently clamped and positioned sheet 3, and the fed sheet 3 will push the sheet 3 at the processing station away from the processing station, thereby realizing automatic feeding while being able to clamp and position the sheet 3 and release the clamp.

[0033] One side of the limit plate 17 is fixedly provided with a mating sleeve 18. The mating sleeve 18 is axially provided with a plurality of second limit holes 181 distributed longitudinally at equal intervals and forms a sliding pair with the second longitudinal plate 152. The second longitudinal plate 152 is provided with a third limit hole 154 along the length direction corresponding to the sliding area of the mating sleeve 18. The third limit hole 154 is coaxially arranged with the selected second limit hole 181 and is tightly connected through a second positioning bolt 19.

[0034] In this embodiment, after the mating sleeve 18 slides on the second longitudinal plate 152, select a second limit hole 181 to align with the third limit hole 154, and then install the second positioning bolt 19 into the aligned second limit hole 181 and third limit hole 154 to achieve tight connection, so as to position the limit plate 17 at the current position. Similarly, it can be positioned at other positions, thereby being able to change the distance between the two limit plates 17 for clamping and limiting sheets 3 of different width specifications.

[0035] Finally, a triangular reinforcement plate 155 is provided at the intersection node of the first longitudinal plate 151, the second longitudinal plate 152 and the transverse plate 153 to enhance the overall structural strength. And a blanking slope 103 is formed at the outer end of the processing station facing away from the storage bin. The sheet 3 after grinding can enter the next station through the blanking slope 103.

[0036] The above embodiments only represent a certain implementation mode of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention should be subject to the appended claims.
