[0039] The embodiments of the present invention are further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the embodiments of the present invention, rather than to limit the embodiments of the present invention. It is also necessary to explain that, for ease of description, only parts related to the embodiments of the present invention are shown in the accompanying drawings, rather than all structures.

[0040] like Figure 1As shown, this embodiment provides an inserter, which includes a manipulator 300, a visual component 400 and a multi-head sorting inserter mechanism. Figure 2 As shown, the manipulator 300 includes a driving mechanism 3100, and the multi-head sorting plug-in mechanism includes a multi-head sorting mechanism 100 and a plug-in assembly 200. The multi-head sorting mechanism 100 is driven and connected to the driving mechanism 3100. By optimizing the multi-head sorting plug-in mechanism, the plug-in machine can reduce the use of cylinders, valves and air pipes, and has the characteristics of simple wiring and small size.

[0041] like Figure 2-4 As shown, the multi-head sorting mechanism 100 includes a valve seat 1, on which at least two groups of sorting shafts 12 are slidably arranged; accordingly, the plug-in assembly 200 includes at least two groups of clamping and inserting mechanisms 2100, and the clamping and inserting mechanisms 2100 include a connecting piece 2111, and the sorting shaft 12 can be selectively extended to connect with the connecting piece 2111, thereby realizing the connection between the multi-head sorting mechanism 100 and the clamping and inserting mechanism 2100, and then when the multi-head sorting mechanism 100 moves, the clamping and inserting mechanism 2100 connected thereto moves accordingly to complete the sorting. By connecting the multi-head sorting mechanism 100 with the clamping and inserting mechanism 2100, the movement of the multi-head sorting mechanism 100 drives the movement of the corresponding clamping and inserting mechanism 2100, which replaces the separate drive cylinder set on each group of clamping and inserting mechanisms 2100, effectively reducing the number of drive cylinders used, and simplifying the structure and wiring. Optionally, a groove is set on the connecting piece 2111 to connect with the sorting shaft 12, which has a simple structure and is easy to operate.

[0042] In this embodiment, six groups of sorting shafts 12 are slidably arranged on the valve seat 1 of the multi-head sorting mechanism 100, and the sorting shafts 12 are distributed circumferentially along the valve seat 1; accordingly, the plug-in assembly 200 includes six groups of clamping and inserting mechanisms 2100, wherein the six groups of clamping and inserting mechanisms 2100 can be selectively distributed circumferentially along the multi-head sorting mechanism 100; each group of sorting shafts 12 corresponds to one group of clamping and inserting mechanisms 2100, and the structure is simple, which can facilitate the connection between the sorting shaft 12 and the connecting piece 2111, and at the same time has better aesthetics. In other embodiments, the number and spatial distribution of the clamping and inserting mechanisms 2100 and the sorting shafts 12 can be selected according to actual needs, such as multiple clamping and inserting mechanisms 2100 and multiple sorting shafts 12 can be arranged in a straight line respectively.

[0043] Specifically, Figure 5-7 The figure shows a multi-head sorting mechanism 100, in which the valve seat 1 includes a cavity 11, a sorting shaft 12 is slidably connected to the cavity 11, and the sorting shaft 12 is connected to a reset spring 13. The sorting shaft 12 can be driven to extend and connect to the connecting piece 2111, and when there is no external force driving the sorting shaft 12, it is driven to retract and disconnect from the connecting piece 2111 by the reset spring 13. Compared with the reset drive method such as pneumatic or other structures, the reset spring 13 has a simple structure and is easy to use.

[0044] Optionally, the sorting shaft 12 is extended by pneumatic drive, and pneumatic drive has the advantages of simple structure, reliability, low cost and convenient maintenance. Specifically, the multi-head sorting mechanism 100 also includes a gas distribution block assembly 2 and at least two groups of control valves 3, wherein the number of control valves 3 corresponds to the number of sorting shafts 12. In addition, the gas distribution block assembly 2 may include a total air inlet 21 and multiple groups of air ports 22 connected to the control valves 3, the air outlet of the control valve 3 is connected to the cavity 11, and the control valve 3 can drive the sorting shaft 12 to selectively extend by controlling the opening and closing of the total air inlet 21 and the cavity 11.

[0045] Specifically, the valve seat 1 is installed above the gas distribution block assembly 2 and the end faces are in contact. The valve seat 1 is provided with a valve seat air inlet 14 connected to the cavity 11, and the gas distribution block assembly 2 is provided with a gas distribution block assembly air outlet 221, so that the valve seat air inlet 14 is connected with the gas distribution block assembly air outlet 221, and the control valve 3 controls the opening and closing of the valve seat air inlet 14 and the main air inlet 21 as needed to drive the sorting shaft 12 to selectively extend. Specifically, when the air circuit of the control valve 3 is connected, the air source enters the first air port 222 of the gas distribution block assembly 2 from the air outlet of the control valve 3, passes through the air circulation hole inside the gas distribution block assembly 2, enters the valve seat air inlet 14 from the gas distribution block assembly air outlet 221, and then enters the cavity 11 to push the sorting shaft 12 to extend. The gas distribution block assembly 2 is in contact with the valve seat 1, so that the multi-head sorting mechanism 100 has a compact structure and a small volume. By setting an internal air circulation hole inside the structure of the gas distribution block assembly 2, the use of the air pipe between the control valve 3 and the valve seat 1 is reduced, making the structure compact. Further optionally, a sealing groove is provided on the outer periphery of the gas distribution block assembly outlet 221, and a sealing ring is provided on the sealing groove to enhance the sealing between the gas distribution block assembly 2 and the valve seat 1, reduce compressed air leakage, and improve production efficiency.

[0046] like Figure 8As shown, in this embodiment, the gas distribution block assembly 2 is provided with a total air inlet 21 and six groups of air inlets 22, the six groups of air inlets 22 are distributed along the circumference of the gas distribution block assembly 2, and the total air inlet 21 is arranged on the circumferential side wall of the gas distribution block 26. Each group of air inlets 22 includes a first air inlet 222, a second air inlet 223 and a third air inlet 224; six groups of control valves 3 are distributed along the circumference of the gas distribution block 26, and are respectively installed on the gas distribution block 26 and contact each other at the end faces. Specifically, the first air port 222 is connected to the air inlet of the control valve 3, and the control valve 3 is connected to the air source through the first air port 222; the second air port 223 is connected to the air outlet of the control valve 3, and when the control valve 3 is actuated and the air circuit is connected, the control valve 3 is connected to the cavity 11 through the second air port 223, and drives the sorting shaft 12 to extend; the third air port 224 is connected to the exhaust port of the control valve 3, and when the control valve 3 is actuated to stop the air supply, the control valve 3 discharges the gas through the third air port 224. The six groups of control valves 3 are installed on the gas distribution block 26, which is convenient for centralized management and has a compact structure. The gas distribution block assembly 2 enables the first air port 222 in each group of air ports 22 to be connected to the main air inlet 21 through the connecting hole, so that all control valves 3 are uniformly supplied with air by the gas distribution block 26, while reducing the use of air pipes.

[0047] In this embodiment, the air distribution block assembly 2 includes an air distribution block 26 and an end cover 24. An annular groove 23 is provided on the end surface of the air distribution block 26. The end cover 24 and the annular groove 23 form an annular connecting hole, and the annular connecting hole is connected to the main air inlet 21 and the six groups of first air ports 222. The air inlet of each control valve 3 can be connected to the main air inlet 21 through the annular connecting hole. Specifically, on the air distribution block 26, the main air inlet 21 is connected to all the first air ports 222 through the connecting hole, that is, the control valve 3 supplies air through the main air inlet 21, instead of each first air port 222 being connected to a single air inlet on the air distribution block 26, which can reduce the number of air inlets on the air distribution block 26, thereby simplifying the structure of the air distribution block 26 and reducing the number of air pipes used. Dividing the annular connecting hole into two structures, the annular groove 23 and the end cover 24, can facilitate processing and reduce costs. The end cover 24 is provided with a groove at the contact end with the gas distribution block 26. The gas distribution block assembly 2 also includes a seal 25, which is provided on the groove to enhance the sealing effect of the annular connecting hole and improve production efficiency. In other embodiments, according to design or processing considerations, the gas distribution block 26 and the end cover 24 are optionally an integral structure, that is, the annular groove 23 and the end cover 24 are an integral annular connecting hole. According to the distribution of the air port 22, the connecting hole can be any other shape. For example, if the air port 22 and the main air inlet 21 are on the same plane, the connecting hole is preferably a linear shape to facilitate processing operations.

[0048] like Fig. 9 and 10As shown, the plug-in assembly 200 also includes a fixing frame 2200 and six elastic fixing members 2112. Each group of the clamping and inserting mechanisms 2100 is connected to the fixing frame 2200 through an elastic fixing member 2112. When the clamping and inserting mechanisms 2100 are not connected to the sorting shaft 12, the clamping and inserting mechanisms 2100 remain stationary under the action of the elastic fixing members 2112. When the clamping and inserting mechanisms 2100 are connected to the sorting shaft 12 and driven by the driving mechanism 3100, the clamping and inserting mechanisms 2100 can overcome the elastic force of the elastic fixing members 2112 and slide relative to the fixing frame 2200. During the movement, the elastic fixing members 2112 always exert a vertical reverse force on the clamping and inserting mechanisms 2100, so that the clamping and inserting mechanisms 2100 can move stably without vibration. Optionally, the elastic fixing members 2112 are coil springs, which have the advantage of providing power without the need for electrical energy.

[0049] In this embodiment, the clamping mechanism 2100 includes a slide bar 2113, which plays the role of supporting the components on the clamping mechanism 2100. The slide bar 2113 is sequentially provided with a first fixed block 2114, a connecting piece 2111, a compression spring 2115 and a second fixed block 2114, and the two ends of the compression spring 2115 are respectively against the fixed block 2114 and the connecting piece 2111. A pressure sensor 2117 is provided on the fixed block 2114, and a trigger rod 2116 is provided on the connecting piece 2111. During the plug-in process of the clamping mechanism 2100, if there is an abnormal error such as inaccurate hole position that causes the plug-in failure, a reverse force will be fed back to the clamping mechanism 2100, thereby pushing the trigger pressure sensor 2117 to contact with the trigger rod 2116, and the pressure sensor 2117 feeds back a signal to a control system such as a programmable logic controller (PLC). Controller, PLC), and then the control system sends a signal to stop the clamping and inserting mechanism 2100 from executing the action, which can effectively avoid product damage caused by incorrect plug-in and improve the stability of the plug-in.

[0050] The clamping and inserting mechanism 2100 is provided with a quick-change joint 2118, which has the function of quick clamping and releasing, and can quickly replace different end tools. One end of the quick-change joint 2118 is fixed on the slide bar 2113, and the other end is provided with a clamping claw cylinder 2119 to complete the clamping and plug-in functions. Accordingly, a tool library can be set up to improve the applicability and flexible production of the plug-in machine according to the needs of different workpieces. Optionally, the slide bar 2113 is a spline shaft, and the spline shaft enables the clamping and inserting mechanism 2100 to have circumferential positioning relative to the fixed frame 2200; further optionally, the slide bar 2113 is set as a hollow shaft, and the air pipe is connected above the hollow shaft, instead of directly connecting the air pipe directly to the clamping claw cylinder 2119, which is convenient for the arrangement of the air pipe and makes the plug-in head more concise as a whole.

[0051] The technical principles of the embodiments of the present invention are described above in conjunction with specific embodiments. These descriptions are only for explaining the principles of the embodiments of the present invention and cannot be interpreted in any way as limiting the protection scope of the embodiments of the present invention. Based on the explanations herein, those skilled in the art can think of other specific implementation methods of the embodiments of the present invention without creative work, and these methods will fall within the protection scope of the embodiments of the present invention.
