[0002] Defect detection equipment uses optical devices or electronic devices such as cameras to inspect the appearance of products. It can accurately detect small defects in objects and effectively improve the inspection efficiency of finished products. However, when inspecting the surface of, for example, plates, manual loading is usually required, which is very time-consuming and labor-intensive. Therefore, a new type of inspection equipment is needed to solve this problem. Utility Model Content

[0003] Other features and advantages of the utility model will be described in the following description, and partly become apparent from the description, or understood by implementing the utility model. The purpose and other advantages of the utility model can be realized and obtained through the structures specifically pointed out in the description and other drawings of the description.

[0004] The utility model aims to overcome the above-mentioned shortcomings and provide a material defect detection device for automatic feeding.

[0005] To achieve the above-mentioned purpose, the technical solution of the utility model is: a material defect detection equipment with automatic feeding, including a detection device and a conveying device, a feeding device is arranged at one end of the conveying device, the feeding device includes a base and a movable frame, the movable frame is slidably connected to the base, the base is provided with a driving mechanism for driving the movable frame to slide back and forth vertically, the movable frame is slidably connected with a grabbing mechanism for grabbing materials, and the base is provided with a linkage mechanism that utilizes the reciprocating sliding of the movable frame to drive the grabbing mechanism to slide back and forth horizontally.

[0006] By adopting the above technical solution, the feeding mechanism places the plate-like material under the movable frame when loading, and the driving mechanism can drive the movable frame to move vertically back and forth. In this way, the grabbing mechanism can continuously grab the material. After grabbing the material, as the movable frame continues to rise, the linkage mechanism will drive the material to move above the conveying device. When the material reaches the top of the conveying device, the grabbing mechanism will release the material, causing the material to fall onto the conveying device, thereby realizing automatic loading of the material. During the descent of the movable frame, the linkage mechanism will drive the grabbing mechanism to reset.

[0007] Preferably, the gripping mechanism includes a sliding box, a connecting piece and a plurality of suction cups, the sliding box has an air cavity inside, the sliding box is provided with a joint for externally connecting to an air pipe, the connecting piece is fixedly connected to the sliding box, the connecting piece has an air passage inside, the air passage is connected to the air cavity, a plurality of suction cups are fixed to the connecting piece at intervals, and the suction cups are connected to the air passage, and the sliding box is provided with a releasing mechanism for releasing the negative pressure state of the air cavity. The utility model can connect to an air pipe externally by using a joint, so that the air in the air cavity can be continuously extracted through the air pipe, so that negative pressure is formed in the air cavity, and when the suction cup is attached to the material, the material can be tightly sucked to achieve the gripping of the material, and the negative pressure state in the air cavity can be released by the releasing mechanism, so that the material can be dropped.

[0008] Preferably, the release mechanism includes a sealing plug and a magnetic block, the sealing plug and the magnetic block attract each other, the sealing plug is slidably connected to the sliding box, the sliding box has an air hole, the sealing plug blocks the air hole, and an elastic member 1 is arranged between the sealing plug and the sliding box. The utility model uses the sealing plug to block the air hole on the sliding box, so that the sliding box can maintain a sealed state after grabbing the material, and when the sliding box moves with the movable frame head, the magnetic block will attract the sealing plug, so that the sealing plug slides in the direction of overcoming the elastic force of the elastic member 1, thereby releasing the blockage of the air hole, so that the air cavity is connected to the atmosphere, and the negative pressure state is released.

[0009] Preferably, the linkage mechanism includes a winding wheel 1 and a pull rope 1, the winding wheel 1 is rotatably connected to the base, the pull rope 1 is wound around the winding wheel 1, one end of the pull rope is fixedly connected to the grabbing mechanism, a torsion spring 1 is provided between the winding wheel 1 and the base, and the movable frame is provided with a reset mechanism for driving the grabbing mechanism to reset. The utility model uses the elastic force of the torsion spring 1 to limit the rotation of the winding wheel 1, and the initial elastic force of the torsion spring 1 is greater than the resistance received by the sliding box when it slides. Therefore, when the movable frame moves downward, the winding wheel 1 will not release the pull rope 1, but pull the sliding box to slide, so that the sliding box slides to the rear end of the movable frame. When the sliding box moves to the end of the movable frame, since the sliding box cannot continue to slide, as the movable frame continues to slide downward, the winding wheel 1 will overcome the elastic force of the torsion spring 1 and rotate, and release the pull rope 1, so that the movable frame can continue to slide downward. In this way, the linkage relationship between the movable frame and the sliding box is realized, so that the grabbing mechanism can reach the top of the material before reaching the material, ensuring that the grabbing mechanism grabs the required position, and when the movable frame moves upward, the torsion spring will first release the elastic force to drive the winding wheel to rotate, and reel in the extra rope. After the reeling is completed, the torsion spring will recover and no longer apply elastic force, and the remaining rope will relax and no longer apply tension to the sliding box. At this time, the reset mechanism will drive the sliding box to move forward, so that the grabbed material can be sent to the top of the conveyor.

[0010] Preferably, the reset mechanism comprises a reel 2 and a pull rope 2, the pull rope 2 is wound around the reel 2, and one end of the pull rope 2 is fixedly connected to the gripping mechanism, the reel 2 is rotatably connected to the movable frame, and a torsion spring 2 is arranged between the reel 2 and the movable frame 2, and the initial elastic force of the torsion spring 1 is greater than the maximum elastic force of the torsion spring 2. In the utility model, when the sliding box slides under the pull of the pull rope 1, the pull rope 2 will be pulled out from the reel 2, so that the reel 2 rotates in the direction of overcoming the elastic force of the torsion spring 2, and when the sliding box no longer receives the pulling force of the pull rope 1, the torsion spring 2 will release the elastic force to drive the reel 2 to reel in the pull rope 2, so that the pull rope 2 pulls the sliding box to reset.

[0011] Preferably, an extension rod is slidably connected in the movable frame, and a second elastic member is provided between the extension rod and the movable frame. The utility model utilizes the extension rod and the second elastic member so that the extension rod of the movable frame can continue to slide under the action of the driving mechanism to overcome the elastic force of the second elastic member after being blocked by the material, so that the grabbing mechanism can always reach the material on the uppermost layer.

[0012] Preferably, the driving mechanism includes a movable block, a reciprocating screw, a guide rod and a motor, the delay rod is fixedly connected to the movable block, the reciprocating screw and the guide rod are both inserted at both ends of the movable block, the reciprocating screw is rotatably connected to the base, the guide rod is fixedly connected to the base, the reciprocating screw is transmission-connected to the movable block, and the motor is transmission-connected to the reciprocating screw through a reduction box. The utility model utilizes a motor to drive the reciprocating screw to rotate, drive the movable block to reciprocate, and thereby realize the driving of the movable frame.

[0013] Preferably, the movable frame is rotatably connected to a guide wheel for guiding the direction of the pull rope 1. The utility model can change the direction of the pull rope 1 by using the guide wheel, so that the pulling force applied by the pull rope 1 to the sliding box can be in the same straight line as the sliding direction of the sliding box, reducing the force required to pull the sliding box.

[0014] In summary, the beneficial effects of the utility model are:

[0015] 1. The driving mechanism can drive the movable frame to move vertically back and forth. In this way, the grabbing mechanism can continuously grab the material. After grabbing the material, as the movable frame continues to rise, the linkage mechanism will drive the material to move above the conveying device. When the material reaches the top of the conveying device, the grabbing mechanism will release the material, causing the material to fall onto the conveying device, thereby realizing automatic loading of the material.

[0016] 2. Use the joint to connect the external vacuum equipment to form negative pressure in the air cavity, which can cooperate with the suction cup to suck the material. When the sliding box moves above the conveying device, the magnetic block can be used to attract the sealing plug to separate the sealing plug from the air hole, thereby releasing the negative pressure state of the air cavity and allowing the material to fall.

[0032] like Figure 1-4 As shown, an automatic feeding material defect detection device includes a detection device 1 and a conveying device 2. A feeding device is arranged at one end of the conveying device 2. The feeding device includes a base 3 and a movable frame 4. The movable frame 4 is slidably connected to the base 3. The base 3 is provided with a driving mechanism for driving the movable frame 4 to slide back and forth vertically. The movable frame 4 is slidably connected with a grabbing mechanism for grabbing materials. The base 3 is provided with a linkage mechanism for utilizing the reciprocating sliding of the movable frame 4 to drive the grabbing mechanism to slide back and forth horizontally.

[0033] By adopting the above technical solution, the feeding mechanism places the plate-like material under the movable frame 4 when feeding, and utilizes the driving mechanism to drive the movable frame 4 to reciprocate vertically. In this way, the grabbing mechanism can continuously grab the material. After grabbing the material, as the movable frame 4 continues to rise, the linkage mechanism will drive the material to move above the conveying device 2. When the material reaches the top of the conveying device 2, the grabbing mechanism will release the material, so that the material falls on the conveying device 2, thereby realizing automatic feeding of the material. During the descent of the movable frame 4, the linkage mechanism will drive the grabbing mechanism to reset.

[0034] The grabbing mechanism includes a sliding box 5, a connecting piece 6 and a plurality of suction cups 7. The sliding box 5 has an air cavity 8. The sliding box 5 is provided with a joint 9 for connecting an external air pipe. The connecting piece 6 is fixedly connected to the sliding box 5. The connecting piece 6 has an air passage inside, and the air passage is connected to the air cavity 8. A plurality of suction cups 7 are fixed on the connecting piece 6 at intervals, and the suction cups 7 are connected to the air passage. The sliding box 5 is provided with a release mechanism for releasing the negative pressure state of the air cavity 8. The joint 9 can be used to connect an external air pipe, so that the air in the air cavity 8 can be continuously extracted through the air pipe, so that a negative pressure is formed in the air cavity 8. When the suction cup 7 is attached to the material, the material can be tightly sucked to achieve the grabbing of the material. The negative pressure state in the air cavity 8 can be released by the release mechanism, so that the material can fall.

[0035] The release mechanism includes a sealing plug 10 and a magnetic block 11. The sealing plug 10 and the magnetic block 11 attract each other. The sealing plug 10 is slidably connected with the sliding box 5. The sliding box 5 has an air hole 24. The sealing plug 10 blocks the air hole 24. An elastic member 12 is provided between the sealing plug 10 and the sliding box 5. The air hole 24 on the sliding box 5 is blocked by the sealing plug 10, so that the sliding box 5 can maintain a sealed state after grabbing the material. When the sliding box 5 moves with the head of the movable frame 4, the magnetic block 11 will attract the sealing plug 10, so that the sealing plug 10 slides in the direction of overcoming the elastic force of the elastic member 12, and the air hole 24 is unblocked, so that the air cavity 8 is connected to the atmosphere, and the negative pressure state is released.

[0036] The linkage mechanism includes a winding wheel 13 and a pull rope 14. The winding wheel 13 is rotatably connected to the base 3. The pull rope 14 is wound around the winding wheel 13. One end of the pull rope is fixedly connected to the grabbing mechanism. A torsion spring 1 is provided between the winding wheel 13 and the base 3. The movable frame 4 is provided with a reset mechanism for driving the grabbing mechanism to reset. The rotation of the winding wheel 13 is limited by the elastic force of the torsion spring 1. The initial elastic force of the torsion spring 1 is greater than the resistance received by the sliding box 5 when it slides. Therefore, when the movable frame 4 moves downward, the winding wheel 13 will not release the pull rope 14, but pull the sliding box 5 to slide, so that the sliding box 5 slides to the rear end of the movable frame 4. When the sliding box 5 moves to the end of the movable frame 4, since the sliding box 5 cannot continue to slide, as the movable frame 4 continues to slide downward, the winding wheel 13 will overcome the elastic force of the torsion spring 1 and rotate, and release the pull rope 14, so that the movable frame 4 can continue to slide downward. In this way, the linkage relationship between the movable frame 4 and the sliding box 5 is realized, so that the grabbing mechanism can reach the top of the material before reaching the material, ensuring that the grabbing mechanism grabs the required position, and when the movable frame 4 moves upward, the torsion spring 1 will first release the elastic force to drive the winding wheel 13 to rotate, and reel in the extra rope 14. After the reeling is completed, the torsion spring 1 is restored and no longer applies elastic force, and the remaining rope 14 is relaxed and no longer applies tension to the sliding box 5. At this time, the reset mechanism will drive the sliding box 5 to move forward, so that the grabbed material can be sent to the top of the conveying device 2.

[0037] The reset mechanism includes a reel 2 15 and a pull rope 2 16. The pull rope 2 16 is wound around the reel 2 15, and one end of the pull rope 2 16 is fixedly connected to the gripping mechanism. The reel 2 15 is rotatably connected to the movable frame 4, and a torsion spring 2 is arranged between the reel 2 15 and the movable frame 4. The initial elastic force of the torsion spring 1 is greater than the maximum elastic force of the torsion spring 2. When the sliding box 5 slides under the pull of the pull rope 14, the pull rope 2 16 will be pulled out from the reel 2 15, so that the reel 2 15 rotates in the direction of overcoming the elastic force of the torsion spring 2. When the sliding box 5 no longer receives the pulling force of the pull rope 14, the torsion spring 2 will release the elastic force to drive the reel 2 15 to reel in the pull rope 2 16, so that the pull rope 2 16 pulls the sliding box 5 to reset.

[0038] An extension rod 17 is slidably connected inside the movable frame 4, and an elastic member 18 is provided between the extension rod 17 and the movable frame 4. By using the extension rod 17 and the elastic member 18, the extension rod 17 can continue to slide under the action of the driving mechanism to overcome the elastic force of the elastic member 18 after the movable frame 4 is blocked by the material, so that the grabbing mechanism can always reach the uppermost material.

[0039] The driving mechanism includes a movable block 22, a reciprocating screw rod 19, a guide rod 20 and a motor 21. The delay rod is fixedly connected to the movable block 22. The reciprocating screw rod 19 and the guide rod 20 are both arranged at both ends of the movable block 22. The reciprocating screw rod 19 is rotatably connected to the base 3. The guide rod is fixedly connected to the base 3. The reciprocating screw rod 19 is transmission-connected to the movable block 22. The motor 21 is transmission-connected to the reciprocating screw rod 19 through a reduction gearbox. The motor 21 is used to drive the reciprocating screw rod 19 to rotate and drive the movable block 22 to reciprocate, thereby realizing the driving of the movable frame 4.

[0040] The movable frame 4 is rotatably connected with a guide wheel 23 for guiding the direction of the pull rope 14. The guide wheel 23 can change the direction of the pull rope 14, so that the pulling force applied by the pull rope 14 to the sliding box 5 can be in the same straight line as the sliding direction of the sliding box 5, reducing the force required to pull the sliding box 5.

[0041] It should be noted that many specific details are set forth in the above description to facilitate a full understanding of the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.
