[0030] In addition, the descriptions of "first", "second", etc. in this application are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.
[0031] This application proposes a material taking device, referring to Figures 1 to 3 The material picking device includes: a mounting member 1; a first suction cup 2, including a first adsorption end and a first connecting end, the first connecting end is arranged on the mounting member 1, the first adsorption end is located on one side of the mounting member 1 and is away from the mounting member 1; a sliding member 4 is slidably connected to the mounting member 1, and the sliding direction is along the direction of the first adsorption end approaching or away from the mounting member 1; and a second suction cup 3 is arranged at one end of the sliding member 4 and is located on the same side of the mounting member 1 as the first suction cup 2, the second suction cup 3 has a second adsorption end away from the mounting member 1; the distance between the first adsorption end and the mounting member 1 is L1, the distance between the second adsorption end and the mounting member is L2, |L1-L2|≥0.
[0032] In this embodiment, the mounting member 1 can be a plate member, and the first suction cup 2 can be fixedly mounted on the mounting member 1 to absorb the target object. At the same time, the second suction cup 3 is arranged on the sliding member 4, so that the sliding member 4 is slidably connected to the mounting member 1. The second suction cup 3 can slide in the direction close to or away from the mounting member 1. When absorbing the target object, the mounting member 1 and the first suction cup 2 move toward the target object. At this time, the absolute value of the difference between L1 and L2 is the largest, and the second suction cup 3 can contact the target object first. After docking with the target object, the absolute value of the difference decreases, and the mounting member 1 continues to move toward the target object. The second suction cup 3 is blocked by the platform for receiving the target object, and the distance between the mounting member 1 becomes smaller and smaller. When the first suction cup 2 contacts and absorbs the target object, the absolute value of the above difference is equal to zero. This situation generally exists in the cutting of flat workpieces. Then the mounting member 1 can be away from the above platform. Under the influence of the dead weight of the target object, the second suction cup 3 and the target object absorbed by it are reset. There is a certain distance between the target object on the second suction cup 3 and the first suction cup 2, which can be used to separate two different targets. In practical applications, the target object may be a workpiece and waste generated after laser cutting. Specifically, the first suction cup 2 may be used to suck the workpiece, and the second suction cup 3 may be used to suck the waste. After the material is taken out, the waste and the workpiece are installed in different positions relative to each other, thereby achieving separation of the waste and the workpiece. Of course, the first suction cup 2 may be used to suck the waste, and the second suction cup 3 may be used to suck the workpiece. The positions of the first suction cup 2 and the second suction cup 3 may be set accordingly based on the positions of the workpiece and the waste. Generally speaking, the first suction cup 2 may be arranged in the middle area of the mounting member 1, and the second suction cup 3 may be arranged close to the edge area of the mounting member 1.
[0033] In some embodiments, reference Figures 1 to 4 The mounting member 1 is provided with a first channel communicating with the first suction cup 2, and the sliding member 4 is provided with a second channel 43 communicating with the second suction cup 3. The first channel and the negative pressure generator can be connected by a pipeline to build negative pressure in the first channel, so that the first suction cup 2 can be used to suck the target object.
[0034] In addition, the sliding member 4 is arranged through the mounting member 1, and the material picking device also includes a joint 5 arranged at one end of the sliding member 4 away from the second suction cup 3, and the joint 5 is connected to the second channel 43. Specifically, the mounting member 1 can be provided with a mounting hole 11, and the sliding member 4 can be a pipe fitting slidably connected to the mounting hole 11, and the internal channel of the pipe fitting is the above-mentioned second channel 43. The second suction cup 3 is arranged at one end of the pipe fitting and is connected thereto. A quick-connect connector 5 is provided at the other end of the pipe fitting, and the joint 5 can be used to connect to an external negative pressure generator through a pipeline. The negative pressures of the first channel and the second channel 43 can be controlled independently. After the material picking is completed, the negative pressure in the second channel 43 can be removed first, and the waste material can be separated from the material picking device. Then, the negative pressure in the first channel is removed, and the workpiece can be placed.
[0035] In some embodiments, reference Figures 1 to 4 A third channel 12 is provided inside the mounting member 1; a mounting hole 11 connected to the third channel 12 is provided on the mounting member 1, and the sliding member 4 is slidably connected to the mounting hole 11; a connecting hole connected to the third channel 12 is provided on the inner wall of the mounting hole 11, and an air hole connected to the second channel 43 is also provided on the sliding member 4, and the air hole is connected to the third channel 12.
[0036] In this embodiment, refer to Figure 5 , an air hole 15 (not shown in the figure) can be set on the side wall of the sliding member 4, and the air hole 15 is connected to the second channel 43 inside the sliding member 4. At the same time, two sealing rings arranged at intervals are set in the mounting hole 11, so that the connecting hole is located between the two sealing rings 14. When the air hole 15 moves with the sliding member 4, its movement range is between the two sealing rings 14, thereby realizing the communication between the first channel and the third channel 12, and the sliding member 4 and the mounting member 1 also have better air tightness. The third channel 12 is set inside the mounting member 1, and the external pipeline is directly connected to the mounting member 1 instead of the sliding member 4, so as to avoid abnormal noise caused by the movement of the external pipeline.
[0037] In some embodiments, reference Figures 1 to 4 The sliding member 4 includes a first section 41 and a second section 42. The outer diameter of the first section 41 is larger than that of the second section 42. The mounting hole 11 is a stepped hole. The first section 41 is located in the section with a larger inner diameter of the stepped hole. The outer wall of the first section 41 is also provided with an air guide groove 44, which runs through both ends of the first section 41. The second channel 43 runs through the sliding member 4 and forms an air hole at the end of the first section 41. The material taking device also includes a plug 13 provided at one end of the mounting hole 11, and a first elastic member provided in the mounting hole 11 and located between the plug 13 and the first section 41. The first elastic member is used to keep the second suction cup 3 away from the mounting member 1.
[0038] In this embodiment, the section with a larger inner diameter of the stepped hole is the third section, and the section with a smaller inner diameter is the fourth section. The second section 42 of the sliding member 4 is slidably connected to the fourth section of the mounting hole 11, and the first section 41 of the sliding member 4 slides in the third section of the mounting hole 11. A step is formed at the connection between the first section 41 and the second section 42, and a step is also formed at the connection between the third section and the fourth section. The step can limit the sliding range of the sliding member 4. The second channel 43 is arranged along the length direction of the sliding member 4 and runs through the first section 41 and the second section 42. Thus, the second channel 43 is connected to the third section. The gap between the first section 41 and the third section is small, which may affect the establishment of negative pressure in the second channel 43. A gas guide groove 44 can be arranged on the periphery of the first section 41 to ensure that the gas guide groove 44 corresponds to the above-mentioned connecting hole, so that the gas enters the third channel 12 through the second channel 43, the mounting hole 11, and the gas guide groove 44 in sequence.
[0039] In this embodiment, the material taking device further includes a sealing ring 14 arranged on the inner wall of the mounting hole 11, the sealing ring 14 is located in the section with a smaller inner diameter of the mounting hole 11, and the sealing ring 14 is adapted to the second section 42. Since the step of the step hole can limit one end of the sliding member 4. A plug 13 can be provided at the port of the mounting hole 11 to limit the other end of the sliding member 4. Prevent the first section 41 from sliding out of the mounting hole 11. At the same time, the mounting hole 11 can also be sealed. The above-mentioned first elastic member can be a spring arranged in the third section of the mounting hole 11, one end of the spring abuts against the plug 13, and the other end abuts against the end of the first section 41. After the second suction cup 3 takes the material, as the mounting member 1 continues to move toward the target object, the spring is compressed until the first suction cup 2 absorbs the target object, the mounting member 1 is away from the platform where the target object is placed, and the elastic force of the spring resets the second suction cup 3. Therefore, the first elastic member enables the second suction cup 3 to reset in time to ensure the separation of waste materials from the workpiece.
[0040] In some embodiments, reference Figures 1 to 5 Of course, the elastic member can be installed not only inside the mounting member 1 but also outside the mounting member 1. The material taking device also includes a second elastic member, which is sleeved on the outer periphery of the sliding member 4. One end of the second elastic member abuts against the second suction cup 3, and the other end abuts against the mounting member 1; the second elastic member is used to keep the second suction cup 3 away from the mounting member 1. Specifically, the second elastic member can also be a spring, and the spring sleeve is provided in a section on the same side of the sliding member 4 and the first suction cup 2. One end of the spring abuts against the mounting member 1, and the other end abuts against the second suction cup 3. The elastic force of the spring makes the second suction cup 3 be in the first section 41. This installation method is simpler.
[0041] The present application also proposes a processing device, referring to Figures 1 to 4 The processing equipment includes the above-mentioned material taking device, and the processing equipment also includes a driving mechanism for driving the material taking device to move. In this embodiment, the driving mechanism can be a manipulator, and the manipulator drives the material taking device to take materials, which has a high degree of freedom.
[0042] In the embodiment of the present application, the principle of the material taking device is as follows:
[0043] The material picking device in the present application includes a mounting member 1, a first suction cup 2, a sliding member 4 and a second suction cup 3. The first suction cup 2 is mounted on the mounting member 1, and the second suction cup 3 is arranged on the sliding member 4. The sliding member 4 is slidably connected to the mounting member 1. The second suction cup 3 can slide in a direction close to or away from the mounting member 1. Relative to the mounting member 1, the second suction cup 3 is in a position beyond the first suction cup 2. When sucking the target object, the mounting member 1 moves toward the target object, and the second suction cup 3 can first contact the target object. After docking with the target object, the mounting member 1 continues to move toward the target object, and the second suction cup 3 slides with the sliding member 4 and approaches the mounting member 1. After the first suction cup 2 contacts and sucks the target object, the mounting member 1 moves away from the above-mentioned platform, and the second suction cup 3 drives the target object to reset. Subsequently, a certain distance is generated between the target object on the second suction cup 3 and the first suction cup 2, and the existence of this distance realizes the separation of different targets.
[0044] The above are only partial or preferred embodiments of the present application. Neither the text nor the drawings can limit the scope of protection of the present application. All equivalent structural changes made using the contents of the present application specification and drawings under the overall concept of the present application, or direct / indirect application in other related technical fields are included in the scope of protection of the present application.
