The premise of oil soaking treatment is to collect pawl products. There are some post-stamping collection devices in the prior art, such as:

[0003] A Chinese patent (publication number CN218611390U, publication date 2023.03.14) discloses a sorting-type punch press material receiving device, including a receiving belt, a frame, a receiving box, a guide member and a driving component; the guide plate is movably connected to the sheet metal member of the guide member through a rotating shaft, and a through hole is provided on the frame at the bottom of the guide member, and the through hole is located directly above the waste box in the frame, and the guide plate is movably connected to the frame through a driving component; a Chinese patent (publication number CN213224053U, publication date 2021.05.18) discloses an automatic collection device for blanking materials of a punch press, including at least one punch press, a receiving mechanism and a main conveyor belt; the receiving mechanism is suitable for collecting products punched out of the punch press and conveying the products to the main conveyor belt, so as to realize automatic receiving of products punched out by multiple punch presses. Since the structure of ratchet products is irregular and the directions after falling are different, the above transmission methods cannot achieve the regular transmission of ratchet products; when transferred to the oil soaking equipment, the contact surface between the ratchet products and the oil is different, which affects the oil soaking effect. Summary of the invention

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide an automatic material collecting device, oil soaking equipment and method for ratchet products, which can enable the ratchet products to be transmitted in a uniform posture, improve the efficiency of oil soaking, and ensure the quality of oil soaking.

[0005] In order to achieve the above object, the present invention is implemented through the following technical solutions:

[0006] In a first aspect, an embodiment of the present invention provides an automatic material receiving device for ratchet products, comprising a conveyor belt, wherein an adjustment area, a shooting area, a gripping area and a material receiving area are sequentially arranged along the conveying direction of the conveyor belt;

[0007] The adjustment area is equipped with a guide component and an adjustment roller so that the ratchet products can pass under the adjustment roller in a flat posture;

[0008] The material receiving area is provided with a grasping robot and a plurality of material receiving boxes, and the material receiving boxes are arranged on the upper side of the moving mechanism; the grasping robot is used to grasp the ratchet products entering the shooting area and place them in the material receiving boxes in a cross-stacked manner.

[0009] As a further implementation, the guide component is disposed at an edge of the conveyor belt and is arranged symmetrically relative to the conveyor belt.

[0010] As a further implementation, the inner side of the guide component is an inclined surface, and the inner sides of the two opposite guide components form a gradually shrinking guide area.

[0011] As a further implementation, the top surface of the guide component is an inclined surface, and is inclined at a set angle from the outside to the inside.

[0012] As a further implementation, the adjustment roller is a brush roller.

[0013] As a further implementation, the shooting area is installed with a camera, which recognizes the ratchet products and transmits a signal to the grasping robot.

[0014] As a further implementation, the installation surface of the moving mechanism is parallel to the conveyor belt, and the moving direction of the material receiving box is perpendicular to the conveying direction of the conveyor belt.

[0015] As a further implementation, the moving mechanism includes a moving platform, and the moving platform is connected to the linear drive mechanism.

[0016] In a second aspect, an embodiment of the present invention further provides an automatic oil-soaking device for ratchet-type products, including the material receiving device;

[0017] It also includes an oil bubble machine, which is arranged at the output end of the material receiving area.

[0018] In a third aspect, an embodiment of the present invention further provides a method for automatically soaking a product in oil, using the automatic soaking device, comprising:

[0019] The punch press discharges the material to the conveyor belt, and the ratchet products are laid flat by the guiding components and the blocking of the adjusting rollers. Then, they are conveyed to the shooting area under the adjusting rollers. After the camera recognizes the ratchet products, the grabbing robot automatically grabs the ratchet products and places them in the receiving box in a cross-stacked manner.

[0022] (1) The upper side of the conveyor belt of the present invention is sequentially provided with an adjustment area, a photographing area, a gripping area and a material receiving area. The adjustment area allows the ratchet products to enter the photographing area in a uniform flat posture. When the photographing area identifies the ratchet products, the gripping robot in the gripping area can be controlled to grip the ratchet products, and then the gripping products are placed regularly in the material receiving area. With the coordinated action of the adjustment area, the photographing area, the gripping area and the material receiving area, the material receiving efficiency is improved.

[0023] (2) The guide component of the adjustment zone of the present invention has an inclined inner side surface and a top surface, which provide preliminary guidance for the ratchet products, so that the ratchet products gradually gather at the adjustment roller, play a role in preliminary shaping, and can prevent the ratchet products from escaping from the conveyor belt, thereby ensuring the accurate transmission of materials; the adjustment roller further changes the posture of the ratchet products, ultimately achieving the purpose of unifying the posture of the ratchet products, providing effective guarantee for subsequent uniform oil soaking.

[0032] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0033] Embodiment 1:

[0034] At present, although some punch press material collecting devices can realize automatic material collection, since the claw products (such as those with claws, ratchet wheels and other structures) are usually irregular in shape, they are easy to deviate from the center position on the conveyor belt, resulting in the inability of the existing punch press material collecting devices to effectively transmit and collect the claw products, affecting the subsequent oil soaking process; Based on this, this embodiment provides an automatic material collecting device for claw products, combined with Figure 1 and Figure 2 As shown, the automatic material receiving device for ratchet products includes a conveyor belt 2, one end of which corresponds to the output end of the punch press discharge belt 1 so as to receive the ratchet products after stamping; an adjustment area, a shooting area, a gripping area and a receiving area are sequentially arranged along the conveying direction of the conveyor belt 2, and the ratchet products are allowed to enter the shooting area in a uniform flat posture through the adjustment area. When the shooting area recognizes the ratchet products, the gripping robot 7 in the gripping area can be controlled to grip the ratchet products, and then the gripping products are placed regularly in the receiving area.

[0035] Specifically, the conveyor belt 2 is installed on the support frame, and its transmission speed is set according to actual requirements. The adjustment area is located at the input end of the conveyor belt 2, and the guide component 3 and the adjustment roller 4 are installed at the input end in sequence according to the conveying direction; the guide component 3 is used to gather the ratchet products to the middle area of ​​the conveyor belt 2, and the adjustment roller 4 is used to flatten the upright ratchet products, unify the conveying state of the ratchet products, and facilitate the regular placement of the collection process.

[0036] In order to ensure that all ratchet products can be transferred to the next process, they need to be initially guided; in this embodiment, two guide components 3 are provided, the guide components 3 are fixed to the edge frame of the conveyor belt 2, and the two guide components 3 are symmetrically arranged relative to the conveyor belt 2.

[0037] In this embodiment, the guide component 3 is made of sheet metal. Figure 3 and Figure 4As shown, the inner side surface and the top surface of the guide component 3 are both inclined surfaces, wherein the angle between the inner side surface of the guide component 3 and the edge frame of the conveyor belt 2 is an acute angle, and the angle between the bottom edge of the inner side surface and the conveying direction is an acute angle, so that a gradually shrinking guide area is formed between the inner side surfaces of the two guide components 3, and the ratchet products transmitted through the punch discharge belt 1 are gradually gathered to the adjustment roller 4, which plays a role in preliminary shaping.

[0038] The top surface of the guide component 3 is also an inclined surface, and the top inclined surface is inclined at a certain angle from the outside to the inside. The purpose of this setting is to prevent some ratchet-like products from falling outside the conveyor belt 2. The top inclined surface serves to guide the ratchet-like products that fall to the top of the guide component 3 to between the two guide components 3, thereby ensuring transmission accuracy and quality.

[0039] Combination Figure 1 and Figure 2 As shown, according to the conveying direction, the adjustment roller 4 is installed on the rear side of the guide component 3 and spans the upper side of the conveyor belt 2. The axis direction of the adjustment roller 4 is perpendicular to the conveying direction; one end of the adjustment roller 4 is connected to the bearing seat, and the other end is connected to the motor or other rotating power. The adjustment roller 4 rotates at a certain speed, and its speed is set according to actual requirements.

[0040] When the ratchet products fall from the punching machine discharge belt 1 to the conveyor belt 2, their states are different. Some ratchet products are in a flat state, and some are in an upright state. If the state of the ratchet products is not adjusted in the input link, the action process of the grabbing robot 7 needs to be increased during the subsequent radiotherapy, which affects the material collection efficiency. Therefore, the present embodiment installs an adjustment roller 4, and the adjustment roller 4 is at a certain height from the conveyor belt 2. The height meets the requirements for the ratchet products in a flat state to pass through, and the ratchet products that do not meet the height change their states under the blocking effect of the adjustment roller 4.

[0041] In order to ensure that the state is adjusted without damaging the pawl products, the adjustment roller 4 of this embodiment is a brush roller, and the upright pawl products can be laid flat by the movement of the brush roller.

[0042] The shooting area is provided with a support frame 6, which is fixed to the frame of the conveyor belt 2, and the camera 5 is installed through the bracket frame so that the camera 5 is located above the conveyor belt 2. When the camera 5 recognizes that a ratchet product passes by, it can send a signal to the grasping robot 7, and the grasping robot 7 grasps the ratchet product according to a predetermined trajectory.

[0043] The material receiving area is provided with a grasping robot 7 and a material receiving box 8. The grasping robot 7 is arranged at the rear side of the support frame 6, and the material receiving box 8 is arranged at the rear side of the grasping robot 7; the grasping range of the grasping robot 7 covers the shooting area and the area above the material receiving box 8.

[0044] In this embodiment, the grasping robot 7 adopts a magnetic material suction method, and the flattened ratchet products are sucked by the magnet at the end of the manipulator.

[0045] The receiving box 8 is placed on the upper side of the moving mechanism, and the moving mechanism can realize the transmission of the receiving box 8, which is convenient for the connection between the full receiving box 8 and the next process. The installation surface of the moving mechanism is parallel to the conveyor belt 2, and the moving direction of the receiving box 8 is perpendicular to the conveying direction of the conveyor belt 2, that is, the conveying direction of the ratchet products is changed, which can reduce the space occupied by the device and make the structure more compact.

[0046] Combination Figure 5 As shown, the moving mechanism includes a moving platform 9 and a linear drive mechanism. The moving platform 9 can be rectangular, circular or other shapes as long as it can place the material receiving box 8. The linear drive mechanism is connected to the moving platform 9 to drive the moving platform 9 and the material receiving box 8 thereon to move in the horizontal direction.

[0047] The mobile platform 9 is slidably connected to the linear guide 11 at its bottom. In the present embodiment, the linear drive mechanism adopts a cylinder 10, and the cylinder rod of the cylinder 10 is connected to the mobile platform 9. It can be understood that in other embodiments, the linear drive mechanism can also be implemented by other methods such as an electric push rod and a hydraulic cylinder.

[0048] Similarly, the structural form of the material receiving box 8 can also be set according to actual requirements, for example, a rectangular parallelepiped structure with an open top is adopted, and the grasping robot 7 can directly put down from the top of the material receiving box 8 after taking the material. The grasping robot 7 is placed in the material receiving box 8 in a cross-stacked manner, for example, the first layer of ratchet products is arranged in multiple rows, and the second layer of ratchet products is arranged in multiple columns, and they are stacked from bottom to top in sequence to form a cross-stacked manner; the capacity of the ratchet products in a material receiving box 8 can be increased, and interference or damage between products can be avoided.

[0049] In this embodiment, the guide component 3 is set to preliminarily adjust the state of the ratchet products, so that they are gathered in the conveying area of ​​the conveyor belt 2, and then the adjustment roller 4 is combined to change the placement state of the ratchet products, so that the ratchet products maintain consistency, which is convenient for the uniformity of the later soaking oil; through the camera 5 recognition combined with the grabbing robot 7, the efficient transfer of the ratchet products can be achieved, and the material collection efficiency can be improved. At the same time, the material collection box 8 is movable, which is convenient for connecting with the next process.

The automatic oil-soaking device of the present embodiment includes an oil-soaking machine 12 and the material receiving device described in Example 1. The oil-soaking machine 12 is arranged at the output end of the material receiving area. After the grasping robot 7 is filled with ratchet products, the material receiving box 8 can be placed in the oil-soaking machine 12 manually, or by adding an additional robot.

[0052] It should be noted that the newly added robot has a manipulator that is capable of grabbing the entire material receiving box 8, for example, a gripper-type manipulator is used.

[0053] The oil soaking machine 12 is an existing device and will not be described in detail here.

[0054] Embodiment 3:

[0055] This embodiment provides a method for automatically soaking oil in a ratchet product, using the automatic soaking oil device described in Embodiment 2, including the following steps:

[0056] The ratchet products fall from the punch discharge belt 1 to the conveyor belt 2, and are gathered in the conveying area of ​​the conveyor belt 2 under the guidance of the guide component 3; when the ratchet products are conveyed to the position of the adjustment roller 4, the products in other states are adjusted to a flat state, and then pass under the adjustment roller 4 and are conveyed to the shooting area.

[0057] The camera 5 recognizes the ratchet products and transmits the signal to the grasping robot 7. The grasping robot 7 rotates to the shooting area to grasp the ratchet products, and then moves to the top of the material receiving box 8 and places them in the material receiving box 8 in a cross-stacking manner; the filled material receiving box 8 moves to the output end under the action of the cylinder 10, and the full material receiving box 8 is transferred to the oil soaking machine 12 manually or robotically.

[0058] The oil-soaking machine 12 descends to soak the oil, and after a set time, the oil-soaking machine 12 rises to take out the ratchet products in the receiving box 8, and the oil-soaking operation is completed.
