Description

Technical Field

[0001] The invention relates to the technical field of hardware product feeding, in particular to automatic feeding equipment for hardware product manufacturing. Background Art

[0002] Hardware products are auxiliary and accessory products used in daily life and industrial production. In the early days, they were mostly made of metal materials such as gold, silver, copper, iron, and tin, hence the name. In addition to various metal materials, non-metallic materials such as plastics and glass fibers are also widely used. Hardware products have played an important role in the survival and development of mankind. In the early days, they were mostly made of metal materials such as gold, silver, copper, iron, and tin, hence the name. In addition to various metal materials, non-metallic materials such as plastics and glass fibers are also widely used. Hardware products have played an important role in the survival and development of mankind.

[0003] Before the traditional processing of square hardware raw materials, a conveyor belt is generally used to transport the raw materials to the calibrated position in sequence. Then, a suction cup or a grasping robot is used to transport the square hardware raw materials at the calibrated position to the processing station. After the processing is completed, the hardware is flattened and taken out by another robot. Thereafter, the feeding robot continues to work in this way and feeds materials intermittently. Because the robot needs to wait for the processing of the square hardware raw materials to be completed before continuing to feed, there needs to be a gap between the square hardware raw materials on the conveyor belt. The raw materials on the conveyor belt are generally placed manually in sequence. Although there can be a gap, the distance between the gaps on each side is difficult to be completely consistent. If this continues for a long time, it is easy to cause two hardware raw materials to accumulate at the calibrated position, affecting the subsequent grasping effect of the robot, resulting in loose grasping or empty grasping, affecting production efficiency. There are still certain inconveniences in actual use. Therefore, automatic feeding equipment for hardware product manufacturing is urgently needed to solve the above problems. Summary of the invention

[0004] In order to overcome the above-mentioned technical problems, the purpose of the present invention is to provide automatic feeding equipment for hardware product manufacturing, so as to solve the problem raised in the above-mentioned background technology that because the robot needs to wait for the processing of the square hardware raw materials to be completed before continuing to feed, there needs to be a gap between the two square hardware raw materials on the conveyor belt, and the raw materials on the conveyor belt are generally placed manually in sequence. Although there can be a gap, the distance of the gap on each side is difficult to be completely consistent. If this continues for a long time, it is easy to cause two hardware raw materials to pile up at the calibrated position, affecting the subsequent grasping effect of the robot, resulting in loose grasping or empty grasping, affecting production efficiency, and there are still certain inconveniences in actual use.

DETAILED DESCRIPTION

[0035] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention. Embodiment 1

[0036] Refer to the attached drawings in the specification Figure 1 , 2 , 4 and 5, the present invention provides an automatic feeding device for hardware product manufacturing, including a conveying mechanism 1, the conveying mechanism 1 includes a bracket 111 and a conveyor belt 110 for conveying and a manipulator for grasping, and the manipulator is located at the discharge of the conveyor belt 110;

[0037] The calibration mechanism 2 includes a calibration plate 210, which is connected to the discharge side of the conveyor belt 110 and is used to place the cube hardware raw materials before grabbing them, and the height of the edges on both sides of the calibration plate 210 is higher than the height of the middle plane;

[0038] The blocking mechanism 3 includes two mounting rods 310, which are symmetrically distributed on both sides of the top of the conveyor belt 110, and the top of each mounting rod 310 is connected with an internally hollow mounting sleeve 311, the inside of the mounting sleeve 311 is movably sleeved with a wire frame rod 312 through a bearing, and the outer sides of the two ends of the wire frame rod 312 are sleeved with a wheel disc, the wire frame rod 312 is composed of two symmetrical reciprocating screw rods, and are welded into an integral component at the midline, the inner surfaces of the two mounting rods 310 are provided with a fixed sleeve 313, and the fixed sleeve 313 is movably sleeved with a linkage shaft 315 through a bearing, a lifting hole 324 is opened on the mounting rod 310, and the end of the linkage shaft 315 extends through the lifting hole 324, one side of the linkage shaft 315 is sleeved with a rubber wheel 314 whose surface is in close contact with the belt surface of the conveyor belt 110, and the other side is sleeved with a wheel disc and a wheel sleeve with the wire frame rod 312. The disks are connected by belts, and two symmetrical screw rod sleeves 316 are rotatably sleeved on the screw rack rod 312. The bottom end of the screw rod sleeve 316 is movably sleeved with an inclined push rod 317 through a rotating shaft, and the bottom end of the push rod 317 is movably sleeved with a push plate 318 through a rotating shaft. At least two pressing holes 319 are provided on the push plate 318, and a T-shaped rod 320 is inserted into the pressing hole 319. The bottom end of the T-shaped rod 320 is connected with a blocking plate 321. The inner surfaces of the two mounting rods 310 are connected with threaded sleeves 322. A threaded rod 323 is rotatably sleeved in the inner hole of the threaded sleeve 322, and the bottom end of the threaded rod 323 is connected to the top of the fixed sleeve 313 through a bearing. The lifting hole 324 is a vertical strip shape for the linkage shaft 315 to move up and down therein. The blocking surface of the blocking plate 321 is concave along the midline, and the surface is covered with a rubber skin with a thickness of at least two millimeters.

[0039] The guiding mechanism 4 is arranged at the feeding side of the conveyor belt 110 .

[0040] When in use, the conveyor belt 110 is started, and the staff intermittently places the square hardware raw materials on the conveyor belt 110. At this time, the rubber wheel 314 will rotate with the movement of the conveyor belt 110, thereby driving the linkage shaft 315 to rotate, and then driving the wire rack rod 312 to rotate continuously through the wheel plate and the belt, and the two screw rod sleeves 316 engaged therewith will reciprocate symmetrically, so that the inclination angle of the pressing plate 217 changes periodically and the push plate 318 moves up and down periodically;

[0041] When the push plate 318 gradually descends, the blocking plate 321 will contact the belt surface. At this time, the push plate 318 continues to descend, causing the T-shaped rod 320 to rise from the pressure hole 319, while the blocking plate 321 remains in position to block a square hardware material. When the push plate 318 descends to the bottom end and rises, the push plate 318 first moves along the T-shaped rod 320 until the end of the T-shaped rod 320 is in close contact with the push plate 318. The push plate 318 continues to rise and then drives the blocking plate 321 to rise, thereby removing the obstruction to the square hardware material and allowing it to continue to move along the conveyor belt 110. The blocking plate 321 will reciprocate to block the next square hardware material, creating a certain distance between it and the previous square hardware material, and finally detaching from the conveyor belt 110 to the top of the calibration plate 210, waiting for mechanical capture. Embodiment 2

[0042] Refer to the attached drawings in the specification Figure 3 The difference between the second embodiment and the above embodiment is that the calibration plate 210 is tilted as a whole, and a blocking bar 211 is connected to the open end side thereof, which is used to block and position the other party's hardware raw materials. Two symmetrical guide plates 212 are arranged on the blocking bar 211, and the two guide plates 212 are both tilted, and an inverted trapezoidal space is formed in the middle, which is used to guide the other party's hardware raw materials. Two symmetrical adjustment holes 213 are provided on the blocking bar 211, and the guide plates 212 are movably sleeved in the adjustment holes 213 through a rotating shaft. The inner surfaces of the ends of the two adjustment holes 213 are connected to first springs 214, and the first springs 214 are in an undeformed state and the adjustment holes 213 are in an inclined state. A moving hole 216 is provided at the midpoint of the blocking bar 211, and a moving hole 216 is inserted into the moving hole 216. A pressure rod 218 is inserted, and a pressure plate 217 is connected to the end of the pressure rod 218 close to the conveyor belt 110, and a pushing strip 219 whose two sides are in contact with the blocking strip 211 is connected to the end of the pressure rod 218 away from the conveyor belt 110. A second spring 220 is connected between the pushing strip 219 and the blocking strip 211, and the second spring 220 is in a non-deformed state, and the pressure plate 217 is not in the moving hole 216. The outer diameter of the square hardware raw material is larger than the aperture of the moving hole 216. When the pressure plate 217 is located in the moving hole 216, the two guide plates 212 are in a parallel state and in contact with the two sides of the square hardware raw material for centering the raw material. Both sides of the pushing strip 219 are movably sleeved with rollers 221 through a rotating shaft, and rubber pads 215 are connected to the clamping surfaces of the two guide plates 212.

[0043] The hardware raw material gradually approaches the blocking bar 211 along the inclined surface of the calibration plate 210, squeezing the pressure plate 217, so that the pressure plate 217 moves into the movable hole 216 and the second spring 220 is stretched. At this time, the pushing bar 219 will squeeze the narrow opening of the guide plate 212 as the pressure plate 217 moves, so that the wide opening of the guide plate 212 gradually approaches until they are parallel, and pushes the hardware raw material to the center. When the robot takes the hardware raw material, the first spring 214 and the second spring 220 release their elastic potential energy to reset each part. Embodiment 3

[0045] When in use, the guide strip 411 can guide the solid hardware material to move to the center line of the conveyor belt 110, and when the infrared sensor 413 does not detect any material passing within the specified time, the adjustment rod 415 descends, so that the dredging rod 418 is close to the surface of the conveyor belt 110, and then the cylinder 416 is started to move the dredging rod 418 back and forth to dredge the open part of the guide strip 411.
