Description

Technical Field

[0001] This application belongs to the field of workpiece handling technology, and more specifically, relates to a suction nozzle assembly and a nail mounting device. Background Technology

[0002] With the rapid development of industrial production technology, people have invented vacuum negative pressure technology for picking up workpieces. This technology is currently widely used in the production of small parts. For example, in battery production, after lithium-ion batteries are filled with electrolyte, the filling port needs to be sealed. During the sealing process, the sealing pin needs to be transferred from the material tray to the lithium-ion battery filling port. The technology used in this process for picking up the workpieces is vacuum negative pressure technology. In this process, the suction nozzle assembly is an indispensable structural component. The suction nozzle assembly needs to be connected to a vacuum generator via an air tube so that the vacuum generator can provide negative pressure to the suction cup of the suction nozzle assembly, thereby enabling the picking up of workpieces such as sealing pins.

[0003] The existing nozzle assembly still has significant structural defects, resulting in unreasonable routing of the air tubes connected to the suction cup. This leads to considerable interference from the air tubes with the movement of the nozzle assembly, affecting its working efficiency. Utility Model Content

[0034] Please see Figure 1 The suction nozzle assembly 100 and the nail-attaching device 10 provided in this application embodiment will now be described. The nail-attaching device 10 provided in this application includes a suction nozzle assembly 100, a drive mechanism 200, and a vacuum generator 300. The nail-attaching device 10 is used in the production and manufacturing of lithium-ion batteries, specifically in the sealing process of transferring sealing nails to the electrolyte filling port of the lithium-ion battery. The vacuum generator 300 provides negative pressure to the suction cup 110 of the suction nozzle assembly 100 to suck up the sealing nails. The drive mechanism 200 drives the suction nozzle assembly 100 to move in space, moving the sealing nails from the tray to the corresponding lithium-ion battery, and driving the suction nozzle assembly 100 to install the sealing nails into the sealing port of the lithium-ion battery. In this embodiment, the drive mechanism 100 is a four-axis robot. In other embodiments, the drive mechanism 100 may also be other drive components that at least drive the suction nozzle assembly 100 to rotate around a central axis z1; these will not be described in detail here.

[0035] Please see Figure 2 , Figure 3 , Figure 4 and Figure 5 This application provides a suction nozzle assembly 100, which is mainly used in the mounting device 10 described in the above embodiments for the sealing process of lithium-ion batteries. Of course, the suction nozzle assembly 100 can also be used in the handling process of other manufacturing industries. Here, this article mainly describes the suction nozzle assembly 100 provided in this application in detail with reference to its application in the mounting device 10.

[0036] Please continue reading. Figure 4 and Figure 5The suction nozzle assembly 100 includes a suction cup 110 and a mounting rod 120. The mounting rod 120 has a central axis z1. Along the central axis z1, the mounting rod 120 includes an air passage portion 122 and a connecting portion 121 connected to the air passage portion 122. The air passage portion 122 is connected to the suction cup 110, and the first end of the connecting portion 121 (not shown in the figure) facing away from the air passage portion 122 is connected to the end rotating shaft 210 of the drive mechanism 200. The air passage portion 122 is provided with a first air passage 1221, and the side wall of the air passage portion 122 is provided with an air tube mounting hole 1220 communicating with the air passage. The suction cup 110 communicates with the first air passage 1221. The connecting portion 121 is provided with a receiving space 1210 to accommodate... The space 1210 is configured to extend from the first end of the connecting part 121 toward the second end (not shown) where the connecting part 121 connects to the air passage 122. The opening 1212 of the receiving space 1210 is located at the end of the first end of the connecting part 121. The side wall of the connecting part 121 is provided with an insertion hole 1211 that communicates with the receiving space 1210. The air pipe (not shown) for connecting the vacuum generator 300 and the first air passage 1221 is configured to pass through the opening 1212 of the receiving space 1210, pass through the insertion hole 1211, and connect with the air pipe mounting hole 1220.

[0037] Specifically, the suction cup 110 is a component with a buffer function used to pick up workpieces such as sealing nails. The suction cup 110 is connected to the mounting rod 120 and communicates with the first air passage 1221. One end of the air pipe can be connected to the air pipe mounting hole 1220 through a connector component such as the air pipe connector 160, and the other end of the air pipe is connected to the vacuum generator 300. Under the action of the vacuum generator 300, a negative pressure is formed inside the suction cup 110, so that the suction cup 110 can pick up the sealing nail component under the action of the internal and external pressure difference. The mounting rod 120 is a component that connects the suction cup 110 to the end rotating shaft 210 of the drive mechanism 200. The mounting rod 120 is connected to the end rotating shaft 210 of the drive mechanism 200, so that the suction cup 110 can rotate in space with the end rotating shaft 210 of the drive mechanism 200. Of course, the drive mechanism 200 also includes a mechanism for driving the end rotating shaft 210 to move horizontally or vertically in space, which will not be described in detail here.

[0038] During operation, the suction cup 110 needs to rotate, move horizontally, or move vertically under the drive of the drive mechanism 200. The nozzle needs to be connected to the vacuum generator 300 via an air tube. Therefore, the routing of the air tube after extending from the air tube mounting hole 1220 will affect the movement of the nozzle assembly 100 in space, especially its rotation. For example, if the air tube routing at the nozzle assembly 100 is unreasonable, the nozzle assembly 100 is easily interfered with by the air tube during rotation, affecting the rotation amplitude of the nozzle assembly 100. This makes the process of tightening the sealing nails through the nozzle assembly 100 overly complicated, thus affecting work efficiency. Furthermore, if the air tube routing at the nozzle assembly 100 is unreasonable, the risk of the sealing nails adsorbed on the suction cup 110 being knocked off by the air tube during rotation or translation will greatly increase, significantly reducing work efficiency.

[0039] Therefore, this application optimizes the mounting rod 120 of the end shaft 210 connecting the suction nozzle and the drive mechanism 200. Specifically, in this embodiment, the mounting rod 120 has an airway portion 122 for forming a first airway 1221 and a connecting portion 121 for connecting to the end shaft 210 of the drive mechanism 200. The connecting portion 121 is provided with a receiving space 1210, and an insertion hole 1211 communicating with the receiving space 1210 is provided on the side wall of the connecting portion 121. An opening 1212 of the receiving space 1210 is provided at the first end of the connecting portion 121. The air tube is connected to the air tube mounting hole 1220. After connection, the tube can be inserted into the receiving space 1210 through the insertion hole 1211 and exit through the opening. Based on this, by setting the receiving space 1210 and the insertion hole 1211 on the mounting rod 120, a structural basis can be provided for the routing of the air tube. This allows the air tube located in the nozzle assembly 100 to be built inside the mounting rod 120 and to exit from the top of the mounting rod 120, thereby effectively reducing the risk of the sealing pin adsorbed on the suction cup 110 being knocked off by the air tube, and thus effectively improving the working efficiency of the nozzle assembly 100. Furthermore, by building the air tube located in the nozzle assembly 100 inside the mounting rod 120, the air tube will not become entangled with the nozzle assembly 100 during its rotation, thereby significantly increasing the rotation range of the nozzle assembly 100 and thus effectively improving the working efficiency of the nozzle assembly 100.

[0040] Of course, the mounting rod 120 described above can also provide a reasonable structural basis for the routing of the air tube at the drive mechanism 200. Specifically, the end shaft 210 of the drive mechanism 200 can be set as a hollow structure, so that the air tube after the end of the mounting rod 120 can further pass through the interior of the end shaft 210 of the drive mechanism 200. This makes the routing of the air tube at the end of the drive mechanism 200 more reasonable, thereby further improving the rotation range of the nozzle assembly 100 and effectively improving the working efficiency of the nozzle assembly 100.

[0041] Furthermore, in this embodiment, the mounting rod 120 is a cylindrical integrally formed part with a central axis z1. The mounting rod 120 enables communication with the air passage of the suction cup 110, and can also be used to arrange the wiring of the air tube. This multi-purpose design can effectively simplify the structural composition of the nozzle assembly 100.

[0042] Please refer to further information. Figure 6 In the reference plane C1 perpendicular to the central axis z1 of the mounting rod 120, the first orifice orientation x2 of the tracheal mounting hole 1220 described in the above embodiment is set at an angle J1 with the second orifice orientation x3 of the insertion hole 1211 described in the above embodiment.

[0043] Specifically, due to the limitations of its material, the trachea experiences significant bending resistance in certain areas when a large bend is required. This makes it difficult for the trachea to bend and insert smoothly. For example, after exiting the trachea mounting hole 1220, the trachea requires a certain amount of bending to smoothly reach the insertion hole 1211. Therefore, to facilitate the routing of the trachea, a certain distance needs to be maintained between the trachea mounting hole 1220 and the insertion hole 1211. This reduces the amount of bending required for the trachea to bend from the mounting hole 1220 into the insertion hole 1211, thereby reducing the bending resistance between the mounting hole 1220 and the insertion hole 1211. This reduces the difficulty of routing the trachea and the risk of the trachea coming out of the insertion hole 1211 due to the bending resistance.

[0044] The trachea typically connects to the insertion hole 1211 via a trachea connector 160. The volume of the trachea connector 160 and the distance between the trachea mounting hole 1220 and the insertion hole 1211 affect the amount of bending of the trachea between these two holes. The positional relationship between the first orifice orientation x2 and the second orifice orientation x3 within the reference plane C1 determines the positional relationship between the trachea mounting hole 1220 and the insertion hole 1211. If the first orifice orientation x2 and the second orifice orientation x3 are aligned in the same direction, then along the central axis z1, the insertion hole 1211 is located directly above the trachea mounting hole 1220. If the length of the mounting rod 120 along the axial direction x1 is constant, it is difficult to meet the required distance between the insertion hole 1211 and the trachea mounting hole 1220, thus affecting the bending requirements of the trachea between these two holes. Therefore, in this embodiment of the application, by setting the orientation of the first orifice x2 and the orientation of the second orifice x3 to be at an angle J1, the distance between the air tube mounting hole 1220 and the insertion hole 1211 can be further increased when the length of the mounting rod 120 along the axial direction x1 is constant. This can effectively improve the space utilization of the mounting rod 120 while also effectively reducing the difficulty of the air tube routing.

[0045] It should be noted that, in this embodiment of the application, the direction parallel to the mounting rod 120 is defined as the axial direction x1.

[0046] Furthermore, the angle J1 between the first orifice orientation x2 and the second orifice orientation x3 described in the above embodiments is greater than or equal to 30° and less than or equal to 90°. If the angle J1 between the first orifice orientation x2 and the second orifice orientation x3 is too small, the distance between the tracheal mounting hole 1220 and the insertion hole 1211 will be too short, affecting the routing of the tracheal tube between the tracheal mounting hole 1220 and the insertion hole 1211. If the angle J1 between the first orifice orientation x2 and the second orifice orientation x3 is too large, the distance between the tracheal mounting hole 1220 and the insertion hole 1211 will be too long, affecting the tightness between the tracheal tube and the mounting rod 120, and increasing the risk of the tracheal tube swaying relative to the mounting rod 120 during rotation. Therefore, in this embodiment of the application, the included angle J1 between the first orifice orientation x2 and the second orifice orientation x3 is set to be greater than or equal to 30° and less than or equal to 90°. For example, the included angle J1 can be set to actual values ​​of 30°, 45°, 60°, 90°, etc., which are greater than or equal to 30° and less than or equal to 90°. This makes the interval between the air tube mounting hole 1220 and the insertion hole 1211 more reasonable and effectively reduces the difficulty of air tube routing.

[0047] Please refer to further information. Figure 7The insertion hole 1211 described in the above embodiment has a first dimension l1 and a second dimension L2. The first dimension l1 is parallel to the central axis z1, and the second dimension L2 is perpendicular to the central axis z1. The first dimension l1 is larger than the second dimension L2. Specifically, the insertion hole 1211 can be shaped like a "racetrack" or a "rectangle". Setting the first dimension l1 to be larger than the second dimension L2 allows the insertion hole 1211 to provide a certain amount of space for the trachea along the x1 axis while restricting the trachea from swinging back and forth in a direction perpendicular to the x1 axis. The fact that the trachea can move to a certain extent along the x1 axis within the insertion hole 1211 effectively reduces the risk of the trachea getting stuck in the hole of the insertion hole 1211 when it is being pulled, causing air suffocation (the so-called air suffocation phenomenon is that the trachea is blocked by the insertion hole 1211 and cannot pass air).

[0048] Please continue reading. Figure 7 The outer contour dimension of the connecting portion 21 described in the above embodiment is larger than the outer contour dimension of the air passage portion 122 described in the above embodiment. Specifically, the air passage portion 122 is the part where the mounting rod 120 connects to the suction cup 110. It is closer to the suction cup 110 than the connecting portion 121. Therefore, the size of the air passage portion 122 has a greater impact on the operation of the suction cup 110 in a confined space. Therefore, the part of the mounting rod 120 near the suction cup 110, i.e., the air passage portion 122, is made relatively smaller. This reduces the impact of the mounting rod 120 on the operation of the suction cup 110 in a confined space, thereby effectively improving the environmental adaptability of the nozzle assembly 100.

[0049] In this embodiment, the connecting portion 121 and the air passage portion 122 described in the above embodiment are both columnar structures. The connecting portion 121 has a first radial dimension L3, and the air passage portion 122 has a second radial dimension L4. The first radial dimension L3 is the dimension of the connecting portion 121 extending in a direction perpendicular to the central axis z1, and the second radial dimension L4 is the dimension of the air passage portion 122 extending in a direction perpendicular to the central axis z1. The first radial dimension L3 is greater than the second radial dimension L4, so that the outer contour dimension of the connecting portion 21 is greater than the outer contour dimension of the air passage portion 122.

[0050] Please refer to further information. Figure 8 The suction nozzle assembly 100 described in the above embodiments further includes: a connector 130, which is connected to the suction cup 110 and the air passage 122. The connector 130 is provided with a second air passage 134, which is connected to the first air passage 1221 and the suction cup 110.

[0051] Specifically, as a replaceable component, the suction cup 110 often requires different models to be replaced depending on the working conditions in practical applications. The mounting rod 120, as a component connecting to the drive mechanism 200, is complex and costly to replace during use. Furthermore, the connection points used by different signal suction cups 110, such as threaded connections, generally have different thread specifications. This means that when replacing the suction cup 110, the existing nozzle assembly 100 also requires replacing the corresponding mounting rod 120. The mounting rod 120, as the connecting part 121 to the drive mechanism 200, has a relatively high manufacturing cost. Therefore, using the suction cup 110 and mounting rod 120 together would significantly increase the operating cost of the nozzle assembly 100. Therefore, by connecting the suction cup 110 to the mounting rod 120 via a connector 130, with the connector 130 serving as the intermediate connecting part 121, the manufacturing and replacement costs can be reduced to some extent compared to using the mounting rod 120.

[0052] Please continue reading. Figure 5 and Figure 8 The suction cup 110, connector 130, and mounting rod 120 described in the above embodiments are connected to each other by threads. Specifically, the airway portion 122 described in the above embodiments has a first internal thread (not shown in the figure) on its inner side, and one end of the suction cup 110 has a first external thread (not shown in the figure). The connector 130 includes a first connecting end 131 and a second connecting end 132 connected to the first connecting end 131. The first connecting end 131 has a second external thread (not shown in the figure) that mates with the first internal thread, and the second connecting end 132 has a second internal thread (not shown in the figure) that matches the first external thread. Thus, the suction cup 110 is connected by the first external thread engaging with the second internal thread of the second connecting end 132 of the connector 130, and the first connecting end 131 of the connector 130 is connected by the second external thread engaging with the first internal thread of the airway portion 122.

[0053] The second external thread described in the above embodiment can be set as a G-thread, which can effectively improve the connection sealing between the first air passage 1221 and the second air passage 134.

[0054] The outer periphery of the connector 130 is also provided with a hexagonal nut structure (not shown in the figure), and the outer periphery of the suction cup 110 is also provided with a hexagonal nut structure. The hexagonal nut structure makes it easy to screw the connector 130 and the suction cup 110, thereby facilitating the connection between the suction cup 110 and the connector 130, and between the connector 130 and the mounting rod 120.

[0055] Please continue reading. Figure 5 and Figure 8The air passage 122 described in the above embodiment is provided with a stepped portion 1222 that is recessed into the first air passage 1221 relative to the end of the air passage 122. An annular limiting groove 1223 is provided on the side wall between the end of the air passage 122 and the stepped portion 1222. The first internal thread starts from the stepped portion 1222 and extends into the first air passage 1221 along the axial direction x1. The connector 130 also includes a limiting portion 133, which is located between the first connecting end 131 and the second connecting end 132 along the axial direction x1. One side of the limiting portion 133 abuts against the stepped portion 1222. The suction nozzle assembly 100 described in the above embodiment also includes a limiting retaining ring 140, which is limited within the annular limiting groove 1223. The limiting retaining ring 140 abuts against the other side of the limiting portion 133 away from the stepped portion 1222 along the axial direction x1. The axial direction x1 is parallel to the central axis z1.

[0056] Specifically, the end of the air passage 122 is the end of the air passage 122 that is axially x1 away from the connecting part 121. The second external thread of the first connecting end 131 of the connector 130 is matched and connected with the first internal thread of the air passage 122. After one side of the limiting part 133 on the connector 130 abuts against the stepped part 1222, the limiting retaining ring 140 is then locked in the annular limiting groove 1223. In this way, the limiting retaining ring 140 can limit the connector 130 along the axial x1, thereby effectively reducing the probability of loosening of the connection between the connector 130 and the mounting rod 120, and thus effectively improving the connection stability between the connector 130 and the mounting rod 120.

The suction nozzle assembly 100 described in the above embodiment also includes a mating block 150, which is disposed in the notch portion 1214. The end rotating shaft 210 is disposed between the mating block 150 and the solid portion 1213 and abuts against the mating block 150 and the solid portion 1213 respectively. The solid portion 1213 and the mating block 150 are detachably connected to clamp the end rotating shaft 210 between the solid portion 1213 and the mating block 150.

[0058] Specifically, the sidewall of the first end of the connecting part 121 is a semi-enclosed structure arranged around the central axis z1. The solid part 1213 is the sidewall of the first end of the connecting part 121, and the notch part 1214 is a notch space arranged radially opposite to the sidewall of the first end along the mounting rod 120. The mating block 150, after being disposed in the notch part 1214, can mate with the solid part 1213, making the first end of the connecting part 121 a semi-fully enclosed structure arranged around the central axis z1. The solid part 1213 and the mating block 150 can be detachably connected by bolts or other components, thereby clamping the end shaft 210 of the drive mechanism 200 between the solid part 1213 and the mating block 150, thus connecting the mounting rod 120 and the drive mechanism 200.
