Description

Technical Field

[0001] This utility model relates to the field of component processing technology, and in particular to a dispensing device. Background Technology

[0002] Dispensing is a process that involves applying fluids such as glue or oil to the surface of a component to seal it itself or to create a seal between components when they are connected. However, existing dispensing devices are mostly used for dispensing along straight lines or planes. For components that require dispensing along a circumferential surface, such as pipe structures, rollers, and sealing rings, continuous and uniform dispensing cannot be achieved, which can easily lead to poor sealing and reduced component quality.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0034] Please see Figure 1 and Figure 2 This utility model provides a dispensing device, including a mounting frame 10, a dispensing component 20, a first moving component 30, and a rotating component 40. The first moving component 30 is mounted on the mounting frame 10 and connected to the dispensing component 20, and can drive the dispensing component 20 to move along a first direction. The rotating component 40 is mounted on the mounting frame 10 and configured to connect with a workpiece (not shown). The rotating component 40 drives the workpiece to rotate around a second direction, which is different from the first direction.

[0035] Understandably, by connecting the workpiece to the rotating assembly 40, the first moving assembly 30 drives the dispensing component 20 to move along the first direction, so that the dispensing component 20 approaches the annular surface of the workpiece to be dispensed with glue. Then, the dispensing component 20 is controlled to apply the fluid to the workpiece. At the same time, the rotating assembly 40 drives the workpiece to rotate around the second direction, that is, so that the dispensing component 20 moves in the circumferential direction relative to the workpiece, thereby enabling the dispensing component 20 to continuously apply the fluid to the annular surface of the workpiece, thus realizing the dispensing of glue to the workpiece.

[0036] The dispensing device of this embodiment can continuously apply fluid to the annular surface of the workpiece during the dispensing process using the dispensing component 20, which is more conducive to achieving uniform dispensing, improving the sealing performance of the workpiece, and improving the quality of the workpiece. Alternatively, it can improve the sealing performance between the workpiece and its connected components when the workpiece is used in a product, thereby improving the quality of the product.

[0037] Understandably, during the process of applying fluid to the annular surface of the workpiece, the dispensing component 20 may move along the first direction, or it may remain stationary.

[0038] For example, the annular surface of the workpiece to be processed can be a circular annular surface, an elliptical annular surface, etc. For instance, if the annular surface of the workpiece to be processed is a circular annular surface, then the dispensing component 20 can be in a stationary state during the process of applying fluid to the annular surface of the workpiece to be processed by the dispensing component 20. If the annular surface of the workpiece to be processed is an elliptical annular surface, then the dispensing component 20 can be in a stationary state during the process of applying fluid to the annular surface of the workpiece to be processed by the dispensing component 20.

[0039] In some embodiments, the dispensing device further includes a second moving component 50 and a third moving component 60. The second moving component 50 is mounted on the mounting frame 10, and a first moving component 30 is drivenly connected to the second moving component 50. The second moving component 50 can drive the first moving component 30 and the dispensing element 20 to move upwards along a third direction, where the first direction and the second direction are different from the third direction. The third moving component 60 is mounted on the mounting frame 10, and a rotating component 40 is drivenly connected to the third moving component 60. The third moving component 60 can drive the rotating component 40 to move along a second direction. It is understood that by having the second moving component 50 drive the first moving component 30 and the dispensing element 20 to move, and the third moving component 60 drive the workpiece to move, the degrees of freedom of the dispensing element 20 and the workpiece to be processed are increased, facilitating the adjustment of the relative position between the dispensing element 20 and the workpiece to be processed. This allows the dispensing element 20 to be brought closer to the annular surface of the workpiece to be dispensed, enabling the dispensing device to adapt to workpieces of different sizes and structures.

[0040] In some embodiments, the first direction, the second direction, and the third direction are perpendicular, so that when the dispensing component 20 and the workpiece move relative to each other, the relative positional relationship between them is more accurate, ensuring that the dispensing component 20 applies the fluid to the area to be dispensed on the workpiece.

[0041] For example, the first direction can be as follows Figure 1 As shown in the Z direction, the second direction can be... Figure 1 The direction perpendicular to the paper, the third direction, such as Figure 1 The X direction is shown in the diagram.

[0042] For example, the first direction is the direction of gravity, and the dispensing part 20 has an opening at the bottom along the direction of gravity, which makes it easier for the fluid to flow out of the dispensing part 20 stably.

[0043] For example, the first moving component 30, the second moving component 50, and the third moving component 60 may each include a drive motor and a lead screw and nut assembly. The drive motor drives the lead screw and nut assembly, which in turn moves the corresponding components. For example, the lead screw and nut assembly in the first moving component 30 moves the dispensing component 20.

[0044] In some embodiments, the dispensing device further includes a base 70, which is disposed on the mounting frame 10. A rotating component 40 is disposed on the side of the base 70 opposite to the mounting frame 10, and the output end of the rotating component 40 protrudes from the base 70 along a second direction. It is understood that the rotating component 40 being disposed on the side of the base 70 opposite to the mounting frame 10 creates a certain gap between the rotating component 40 and the mounting frame 10. The output end of the rotating component 40 protrudes from the base 70 along the second direction, and the workpiece is connected to the portion of the output end of the rotating component 40 that protrudes from the base 70. This arrangement allows the workpiece to be spaced apart from both the mounting frame 10 and the base 70, facilitating the rotation of larger workpieces around the second direction. This enables the dispensing device to dispense adhesive to workpieces of various sizes, improving the adaptability of the dispensing device.

[0045] For example, the base 70 may include a top plate 71 and a bottom plate 72 spaced apart along a first direction, and two side plates 73 connecting the top plate 71 and the bottom plate 72. The two side plates 73 are spaced apart relative to each other, which makes it easier to install the base 70.

[0046] In some embodiments, the rotating assembly 40 includes a rotary motor 41 and a transmission assembly, the rotary motor 41 being mounted on the mounting bracket 10. The transmission assembly is drively connected to the rotary motor 41 and is configured to connect to the workpiece. By driving the transmission assembly through the rotary motor 41, the transmission assembly can cause the workpiece to rotate about a second direction, while also facilitating the control of the workpiece's rotational speed through the transmission assembly.

[0047] Understandably, there can be one or more transmission components, with intervals between them.

[0048] For example, there are multiple dispensing components 20 and multiple transmission assemblies. The multiple dispensing components 20 are spaced apart along a third direction upwards, and multiple sets of transmission assemblies are also spaced apart along a third direction upwards, so as to simultaneously dispense adhesive onto multiple parts to be processed. For example... Figure 1 and Figure 2 As shown,

[0049] Furthermore, the transmission assembly includes a first transmission wheel 42, a rotating shaft 43, a second transmission wheel 44, and a transmission belt 45. The first transmission wheel 42 is connected to the output shaft of the rotary motor 41. The rotating shaft 43 is rotatably connected to the mounting bracket 10 and is configured to connect to the workpiece to be processed. The second transmission wheel 44 is connected to the rotating shaft 43. The transmission belt 45 is wound around the outer periphery of the first transmission wheel 42 and the second transmission wheel 44. The rotary motor 41 drives the first transmission wheel 42 to rotate, and the first transmission wheel 42 drives the second transmission wheel 44, the rotating shaft 43, and the workpiece to be processed to rotate in a second direction via the transmission belt 45.

[0050] For example, the outer periphery of the first transmission wheel 42 and the second transmission wheel 44 is provided with first transmission teeth, and the inner ring of the transmission belt 45 is provided with second transmission teeth. The first transmission teeth and the second transmission teeth mesh with each other to enhance the transmission stability of the transmission assembly.

[0051] For example, such as Figure 2 As shown, multiple transmission components can use the same first transmission wheel 42.

[0052] Furthermore, the first drive wheel 42 and / or the second drive wheel 44 include a first segment 421, a second segment 422, and a third segment 423 arranged sequentially along the second direction. A first stepped surface is formed between the first segment 421 and the second segment 422, and a second stepped surface is formed between the second segment 422 and the third segment 423. The drive belt 45 is wound around the outer periphery of the second segment 422. The first and second stepped surfaces are used to restrict the movement of the drive belt 45 along the second direction. It is understood that the outer diameters of the first segment 421 and the third segment 423 are larger than the outer diameter of the second segment 422, such that a first stepped surface is formed between the first segment 421 and the second segment 422, and a second stepped surface is formed between the second segment 422 and the third segment 423. The drive belt 45 can abut against the first stepped surface and / or the second stepped surface, restricting the movement of the drive belt 45 in the second direction, preventing the drive belt 45 from coming off, and ensuring the stability of the transmission assembly.

[0053] For example, the outer periphery of the second segment 422 is provided with a first transmission tooth.

[0054] In some embodiments, the rotating assembly 40 further includes a support 46, which includes two mounting portions 461 spaced apart along a second direction. Each mounting portion 461 has a mounting hole. The rotating shaft 43 is rotatably connected to the mounting holes of the two mounting portions 461. The second transmission wheel 44 is located between the two mounting portions 461. This enhances the rotational stability of the rotating shaft 43, allowing the workpiece connected to the rotating shaft 43 to rotate stably and improving the dispensing quality.

[0055] For example, such as Figure 1 and Figure 2 As shown, the support 46 includes a connecting portion 462 and two mounting portions 461, with the two mounting portions 461 located on the same side of the connecting portion 462. The connecting portion 462 protrudes from at least one side of the two mounting portions 461 along a third direction, facilitating the connection of the connecting portion 462 to the base body 70 via fasteners.

[0056] For example, such as Figure 1 and Figure 2 As shown, the rotating assembly 40 includes two supports 46, which are spaced apart along a third direction, and two transmission assemblies are rotatably connected to the two supports 46 respectively.

[0057] In some embodiments, the workpiece is fastened to the rotating assembly 40 by fasteners, thereby connecting the workpiece and the rotating assembly 40.

[0058] For example, the rotating shaft 43 of the rotating assembly 40 is provided with a threaded hole, and the fastener can be a screw or bolt. The shank of the fastener can pass through the workpiece and engage with the threaded hole of the rotating shaft 43 to fasten the workpiece to the rotating assembly 40.

[0059] In other embodiments, the rotating assembly 40 includes a connector 47, which has a slot 471 on one side along the second direction, into which the workpiece to be processed is engaged. It is understood that when the workpiece is engaged in the slot 471, the annular surface of the workpiece to be glued is located outside the slot 471, thus connecting the workpiece to the transmission assembly, facilitating the assembly and disassembly of the workpiece, and improving the efficiency of glue dispensing.

[0060] For example, the connector 47 can be connected to the rotating shaft 43 by magnetic attraction, or the connector 47 can be connected to the rotating shaft 43 by fasteners.

[0061] For example, such as Figure 1 and Figure 2 As shown, the connector 47 may include a first part and a second part connected together. The first part may be sleeved on the outer periphery of the rotating shaft 43 to ensure the connection stability between the connector 47 and the rotating shaft 43. The second part may be provided with a slot 471.

[0062] For example, the outer diameter of the second part may be larger than that of the first part, so as to control the overall weight of the connector 47 while matching the size of the slot 471 of the second part with that of the workpiece to be processed.

[0063] Furthermore, the connector 47 is also provided with a clearance groove 472 that connects to the slot 471. It can be understood that by providing a clearance groove 472 on the connector 47, it is possible to facilitate, for example, the insertion of a robotic arm or human hand, to engage the workpiece to be processed into the slot 471 of the connector 47 and to remove the workpiece from the connector 47.

[0064] For example, the clearance groove 472 extends through the outer surface of the connector 47.

[0065] For example, there may be one or more clearance slots 472.

[0066] like Figure 2 As shown, the clearance groove 472 is provided with two clearance grooves 472. A robot or human hand can reach into the two clearance grooves 472 and clamp the workpiece to be processed, and remove the workpiece from the connector 47.

[0067] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
