Description

Technical Field

[0001] The utility model relates to the technical field of feeding devices, in particular to an automatic feeding device and a production system. Background Art

[0002] In the process of making the front shell of the mobile phone, the hardware needs to be implanted into the mold for injection molding. The existing automatic feeding device includes a feeding mechanism and a positioning mechanism. The outer edge of the positioning mechanism is provided with a limit block, and the limit block surrounds the positioning groove. The feeding mechanism grabs the hardware and moves to the top of the positioning groove. The feeding mechanism releases the hardware to make the hardware fall into the positioning groove. The positioning groove positions the hardware, and the manipulator grabs the hardware and puts it into the mold. The positioning mechanism relies on the inner wall of the limit groove to limit the hardware. In order to facilitate the falling of the hardware, the area surrounded by the inner wall of the positioning groove is often larger than the area of ​​the hardware. The positioning groove has poor positioning accuracy and is prone to cause the hardware to deflect after falling. In addition, the manipulator directly grabs the hardware and puts the hardware into the mold in a deflected state, which will damage the mold. Utility Model Content

[0025] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0026] Combine the following Figures 1 to 3 , describing an embodiment of the utility model.

[0027] According to an embodiment of the present utility model, on the one hand, an automatic loading device is provided, comprising a positioning mechanism 1 and a material taking and placing mechanism 2 . The positioning mechanism 1 includes a supporting platform 101 and a positioning component 102, and the positioning component 102 includes a bearing platform 1021, a fixed limit block 1022, a movable limit block 1023 and a correction drive mechanism 1024; the bearing platform 1021 and the correction drive mechanism 1024 are both arranged on the supporting platform 101, and the fixed limit block 1022 is attached to the outside of two adjacent side walls of the bearing platform 1021; the movable limit block 1023 is arranged outside the other two side walls of the bearing platform 1021, and the driving end of the correction drive mechanism 1024 is connected to the movable limit block 1023; the material taking and releasing mechanism 2 is used to grab the material 6 and place the material 6 on the bearing platform 1021; the correction drive mechanism 1024 is used to drive the movable limit block 1023 to move toward the fixed limit block 1022, so as to position the material 6 in the limit space enclosed between the fixed limit block 1022 and the movable limit block 1023.

[0028] When the automatic feeding mechanism 4 of this structure is working, the material picking and discharging mechanism 2 grabs the material 6 and transports the material 6 to the top of the supporting platform 1021, the movable limit block 1023 first moves away from the fixed limit block 1022, the material picking and discharging mechanism 2 releases the material 6, and the material 6 automatically falls onto the supporting platform 1021, and the correction drive mechanism 1024 drives the movable limit block 1023 to move toward the side wall of the supporting platform 1021, so that the material 6 moves toward the fixed limit block 1022, and the material 6 abuts against the inner wall of the fixed limit block 1022 and the movable limit block 1023. The material 6 is positioned in the limiting space surrounded by the fixed limit block 1022 and the movable limit block 1023, so as to automatically correct the material 6 with an offset position, which can significantly improve the positioning accuracy of the material 6; the subsequent transfer mechanism such as a manipulator grabs the material 6 from the supporting platform 1021 and puts the material 6 into the mold, which can improve the position accuracy of the material 6 when it is placed and prevent damage to the mold. Optionally, as Figure 2 As shown, in one embodiment, there are two movable limit blocks 1023, and the movable limit blocks 1023 are arranged one by one on the outside of the two side walls of the carrier 1021, and the correction drive mechanism 1024 is arranged one by one on the movable limit blocks 1023. The two movable limit blocks 1023 are respectively arranged outside the two adjacent side walls of the carrier 1021, and the driving end of each correction drive mechanism 1024 is respectively connected to a movable limit block 1023, and the driving ends of the two correction drive mechanisms 1024 are perpendicular to each other. When the material 6 falls onto the carrier 1021, the two correction drive mechanisms 1024 respectively drive the two movable limit blocks 1023 to move toward the side walls of the carrier 1021, so that the movable limit blocks 1023 push the material 6 and make the material 6 abut against the inner wall of the fixed limit block 1022.

[0029] like Figure 2 As shown, in some embodiments, the cross-section of the support platform 1021 parallel to its support surface is rectangular, and the correction drive mechanism 1024 drives the movable limit block 1023 to move toward the fixed limit block 1022 to position the material 6 in the rectangular limit space enclosed between the fixed limit block 1022 and the movable limit block 1023.

[0030] In other embodiments, another movable limit block 1023 may be provided. In this case, the movable limit block 1023 is in an "L"-shaped block, which includes two limit blocks that are interconnected and perpendicular to each other. In this case, one correction drive mechanism 1024 is provided, and the driving end of the correction drive mechanism 1024 is connected to the corner of the movable limit block 1023.

[0031] Optionally, in one embodiment, the correction drive mechanism 1024 includes a cylinder, and the end of the piston rod of the cylinder is connected to the movable stop block 1023 .

[0032] Preferably, the cylinder is a double-rod cylinder, which has high movement accuracy and good operation stability, and can accurately push the movable limit block 1023 toward the side wall of the supporting platform 1021, thereby improving the positioning accuracy of the positioning mechanism 1 for the material 6.

[0033] In other embodiments, the correction drive mechanism 1024 may further include an electric cylinder.

[0034] Alternatively, if Figure 2 As shown, in one embodiment, two fixed limit blocks 1022 are provided, and the two fixed limit blocks 1022 are respectively attached to the outside of two adjacent side walls of the carrier 1021. Compared with providing an "L"-shaped fixed limit block 1022, two independent straight-shaped fixed limit blocks 1022 are more convenient to install and fix, and it is convenient to attach the inner side wall of the fixed limit block 1022 to the side wall of the carrier 1021.

[0035] In one embodiment, Figure 2 As shown, the positioning mechanism 1 also includes a first detection mechanism 103, which is arranged inside the carrier 1021, and the top surface of the first detection mechanism 103 does not exceed the bearing surface at the top of the carrier 1021. The first detection mechanism 103 is used to detect whether there is material 6 above the carrier 1021. When the manipulator takes the material 6 from the carrier 1021, the first detection mechanism 103 detects that there is no material 6 on the carrier 1021, then the material taking and placing mechanism 2 grabs new material 6 and puts the new material 6 into the carrier 1021. After the first detection mechanism 103 detects that the material 6 is in place, the grabbing end of the manipulator moves to the top of the carrier 1021 to grab the material 6. The top surface of the first detection mechanism 103 does not exceed the bearing surface at the top of the carrier 1021, so that the material 6 falls to the carrier 1021 and is placed horizontally on the carrier 1021.

[0036] Specifically, in this embodiment, a groove is provided on the supporting platform 1021 , and the first detection mechanism 103 is disposed in the groove.

[0037] Optionally, material 6 is the hardware required in the production process of the front shell of the mobile phone. Since the hardware is relatively thin, when the material taking and releasing mechanism 2 grabs the hardware, multiple hardware pieces are easily stacked together, and the hardware pieces are stacked on the supporting platform 1021. After the manipulator takes the material, it puts multiple stacked hardware pieces into the mold, which will crush the mold. In order to solve this problem, in one embodiment, the positioning mechanism 1 also includes a second detection mechanism (not shown in the figure), the second detection mechanism is arranged on one side of the supporting platform 1021, the detection end of the second detection mechanism is arranged toward the inside of the supporting platform 1021, the detection end of the second detection mechanism is higher than the bearing surface of the supporting platform 1021, and the second detection mechanism is used to detect whether there are more than two pieces of material 6 stacked above the supporting platform 1021. The thickness of the hardware is the same. If only one piece of hardware is placed on the carrier 1021, the height of the detection end of the second detection mechanism is higher than the height of one piece of hardware, and the second detection mechanism detects that there is no material 6 stacked, then the manipulator receives the signal and moves to the top of the carrier 1021 to pick up the material; when there are two or more pieces of material 6 stacked on the carrier 1021, the second detection mechanism detects that there are two or more pieces of material 6 stacked, and the manipulator does not receive the signal and suspends picking up the material. The picking and unloading mechanism 2 takes away the excess hardware stacked on the carrier 1021, thereby preventing the hardware from stacking and preventing the mold from being crushed after multiple pieces of hardware are placed in the mold at the same time.

[0038] like Figure 2 As shown, the fixed limit block 1022 outside one side of the support platform 1021 includes two limit blocks arranged in sections, a gap is formed between the two limit blocks, the second detection mechanism is arranged at the position of the gap, and the detection end of the second detection mechanism is directed toward the top of the support platform 1021 through the gap.

[0039] like Figure 1 and Figure 3 As shown, in one embodiment, the automatic feeding device further includes a linear drive mechanism 3 and a feeding mechanism 4, and the feeding mechanism 4 is used to carry the material 6; the picking and unloading mechanism 2 includes a lifting drive mechanism 201 and a suction cup 202, and the suction cup 202 is connected to the driving end of the lifting drive mechanism 201, and the lifting drive mechanism 201 is connected to the driving end of the linear drive mechanism 3, and the linear drive mechanism 3 drives the picking and unloading mechanism 2 to reciprocate between the upper part of the feeding mechanism 4 and the upper part of the carrying platform 1021. The linear drive mechanism 3 drives the picking and unloading mechanism 2 to move to the upper part of the feeding mechanism 4, and the lifting drive mechanism 201 drives the suction cup 202 to descend and suck the material 6, and the linear drive mechanism 3 then drives the picking and unloading mechanism 2 to move to the upper part of the carrying platform 1021, and the suction cup 202 releases the material 6 so that the material 6 falls onto the carrying platform 1021, thereby realizing the automatic grasping and releasing of the material 6, and realizing the automatic switching of the picking and unloading mechanism 2 between the loading station and the unloading station.

[0040] like Figure 1 and Figure 3As shown, the automatic loading device further includes a plurality of columns 5, a support frame is disposed above the columns 5, and the support platform 101 and the linear drive mechanism 3 are both disposed on the support frame.

[0041] Optionally, in one embodiment, the lifting drive mechanism 201 is a cylinder, and the linear drive mechanism 3 is a linear module.

[0042] like Figures 1 to 3 As shown, the positioning assembly 102 is provided with at least two groups, and the loading mechanism 4, the material picking and placing mechanism 2 and the linear drive mechanism 3 are all arranged in one-to-one correspondence with the positioning assembly 102. All the material picking and placing mechanisms 2 pick up materials at the same time, and the linear drive mechanism 3 drives each material picking and placing mechanism 2 to the top of the carrier 1021 respectively, and the material 6 falls onto each carrier 1021. The correction drive mechanism 1024 is actuated to correct the position of each material 6, and the manipulator grabs the materials 6 on all the carriers 1021 at the same time, so as to implant more than two materials 6 into the mold at the same time, thereby improving production efficiency.

[0043] Optionally, in one embodiment, Figure 1 and Figure 2 As shown, there are two groups of positioning components 102, and two groups of feeding mechanism 4, material picking and placing mechanism 2 and linear drive mechanism 3 are also provided. The material picking and placing mechanism 2 is arranged above the feeding mechanism 4 and the positioning mechanism 1. There are four columns 5, and a support frame is arranged above every two columns 5. The support frame is in the shape of a rectangular frame, and the support platform 101 is fixed on the support plate at the bottom of the support frame, and the linear drive mechanism 3 is fixed on the support plate at the top of the support frame.

[0044] like Figure 3 As shown, in one embodiment, the feeding mechanism 4 includes a lifting drive mechanism (not shown in the figure), a top plate 401, a pad 402, a bottom support plate 403 and a side baffle 404. The side baffle 404 is arranged on the bottom plate, the driving end of the lifting drive mechanism is connected to the top plate 401, the pad 402 is arranged above the top plate 401, and the material 6 is stacked on the pad 402. The lifting drive mechanism drives the top plate 401 to rise to lift the material 6 to a specified height, so that the material taking and unloading mechanism 2 can take the material. Every time the material taking and unloading mechanism 2 takes away a piece of material 6, the lifting drive mechanism drives the material 6 to rise so that the material 6 on the top is kept at a predetermined height.

[0045] Alternatively, if Figure 3 As shown, each feeding mechanism 4 includes four side baffles 404, each side baffle 404 includes two mutually perpendicular connecting plates, and the four side baffles 404 enclose a rectangular space for accommodating the material 6. Figure 3 As shown, the top of the side baffle 404 is tilted outward, which can facilitate placing the material 6 on the pad 402, and also facilitate the material taking and unloading mechanism 2 to take the material 6 from the loading mechanism 4.

[0046] According to an embodiment of the present invention, on the other hand, a production system is provided, including the above-mentioned automatic loading device and transfer mechanism, the transfer mechanism is used to grab the material 6 on the carrier 1021 and put the material 6 into the mold.

[0047] When the production system of this structure is working, the material 6 is placed on the pad 402 of the loading mechanism 4, the material picking and unloading mechanism 2 grabs the material 6 and transports the material 6 to the top of the supporting platform 1021, the suction cup 202 releases the material 6, and the material 6 automatically falls onto the supporting platform 1021, and the correction drive mechanism 1024 drives the movable limit block 1023 to move toward the side wall of the supporting platform 1021 to automatically correct the material 6 with offset position, which can significantly improve the positioning accuracy of the material 6; the transfer mechanism grabs the material 6 from the supporting platform 1021 and places the material 6 into the mold, which can improve the position accuracy of the material 6 when it is placed and prevent damage to the mold.

[0048] A transfer mechanism such as a manipulator is used to grab the material 6 on the carrier 1021 and place the material 6 into the mold; in one embodiment, Figure 2 As shown, the positioning mechanism 1 also includes a positioning guide 104, which is arranged on the supporting platform 101. A matching piece is provided on the transfer mechanism.
