Description

Technical Field

[0001] The utility model belongs to the field of mechanical technology and relates to the processing of precision parts, in particular to a welding part feeding suction nozzle assembly. Background Art

[0002] In the 3C manufacturing industry, such as mobile phones and computers, there are many special-shaped parts to be assembled. Since special-shaped parts are non-standard parts, and the parts are small in size and of different shapes, they are not conducive to clamping and handling. Therefore, different fixtures need to be designed for different special-shaped parts, which increases production costs and is not conducive to industrial production. At the same time, due to the small size of special-shaped parts, they are easily deformed by external forces and are easily damaged during the clamping and handling process. Utility Model Content

[0003] The utility model discloses a welding part feeding suction nozzle assembly, which solves the problem of adaptation between the existing clamp and the special-shaped parts and the problem that the parts are easily deformed after being clamped by the clamp.

[0004] The welding parts feeding nozzle assembly is used as a parts grabbing device in the welding parts handling process. The feeding nozzle assembly includes:

[0005] Assembly rack;

[0006] A connecting seat, slidably connected to the assembly frame;

[0007] A driving member, used for driving the connecting seat to slide on the assembly frame;

[0008] A nozzle body, comprising a connection end connected to the connection seat, and a suction end for suctioning welding parts;

[0009] A negative pressure channel is arranged in the suction nozzle body, one end of the negative pressure channel is used to connect to the vacuum pumping device, and the other end is open to the suction end.

[0010] The present application adopts negative pressure adsorption for the transportation of special-shaped parts (for example, welding parts). Since the parts are small in size and usually light in weight, the negative pressure adsorption method can also keep the parts stable during the transportation process, thereby avoiding the problem of damage to the parts during clamping. In addition, the adsorption method does not require targeted mold opening for different parts, thereby improving versatility and solving cost issues.

[0011] Several optional methods are also provided below, but they are not intended to be additional limitations on the above-mentioned overall solution, but are merely further supplements or preferences. Under the premise that there are no technical or logical contradictions, each optional method can be combined with the above-mentioned overall solution separately, and multiple optional methods can also be combined.

[0012] Optionally, the nozzle body further includes an adjusting member, which is located at the adsorption end and is interference fit with the inner wall of the negative pressure channel, and the adjusting member is provided with at least one through hole.

[0013] Optionally, the assembly frame is provided with a slide rail and a slider that cooperate with each other, the slide rail is arranged in a vertical direction, the connecting seat is connected to the slider and moves up and down along the slide rail, the suction nozzle body is located below the connecting seat, and the driving member is located above the connecting seat.

[0014] Optionally, the driving member includes a telescopic cylinder and a transmission rod, and the telescopic cylinder and the connecting seat are transmitted through the transmission rod.

[0015] Optionally, the driving member further includes a buffer spring, one end of which acts on the transmission rod, and the other end of which acts on the connecting seat.

[0016] Optionally, an adjustable limiting structure is provided on the assembly frame, and a limiting unit cooperating with the limiting structure is provided on the connecting seat.

[0017] The beneficial effects of this application are as follows:

[0018] 1. This application adopts negative pressure adsorption to fix welding parts during transportation. Compared with the traditional clamping method, it can avoid damage to the parts caused by clamping. At the same time, the adsorption method solves the structural adaptation problem when grasping the parts, and improves the versatility.

[0019] 2. The present application provides an adjustment member at the suction end of the suction nozzle body to reduce the aperture of the negative pressure channel and increase the number of through holes at the suction end that can form negative pressure, thereby further improving the adaptability with welding parts of different shapes.

[0020] 3. When the nozzle body in the present application moves downward, it can be buffered by the buffer spring, thereby reducing the pressure on the welding part when the nozzle body contacts the welding part and avoiding deformation of the welding part. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0033] It should be noted that when a component is referred to as being "connected" to another component, it may be directly connected to the other component or there may be a central component. When a component is referred to as being "disposed on" another component, it may be directly disposed on the other component or there may be a central component at the same time.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those generally understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0035] refer to Figure 1 and Figure 2 In one embodiment of the present application, a welding part feeding nozzle assembly is disclosed. As a part grabbing device in the process of welding part handling, the feeding nozzle assembly includes: a nozzle body 4 with a negative pressure channel 43 and an assembly frame 1. The assembly frame 1 is connected with a connecting seat 2 and a driving member 3. The connecting seat 2 is slidably connected to the assembly frame 1. The driving member 3 is fixed on the assembly frame 1 and provides the connecting seat 2 with power to slide on the assembly frame 1. The nozzle body 4 is connected to the connecting seat 2 and moves synchronously with the connecting seat 2.

[0036] like Figure 3 As shown, the nozzle body 4 has a connection end 41 connected to the connection base 2 and a suction end 42 for sucking the welding parts.

[0037] In some embodiments, the suction end 42 may be configured to be tapered to accommodate smaller parts.

[0038] Further, such as Figure 3 and Figure 4 As shown, the nozzle body 4 also includes an adjusting part 44, which is located at the adsorption end 42 and has an interference fit with the inner wall of the negative pressure channel 43. The adjusting part 44 is used to reduce the inner diameter of the negative pressure channel 43, and increase the adsorption force of the adsorption end 42 under the premise of inconvenient air flow in the negative pressure channel 43, and can adapt to smaller parts.

[0039] Furthermore, at least one through hole 45 is provided on the adjusting member 44. In some embodiments, the through holes 45 can be multiple and distributed in an array. When adsorbing some special-shaped parts, some of the through holes 45 can act on the parts to complete the adsorption, further improving the versatility.

[0040] In some embodiments, the adjusting member 44 may be made of a rubber member to increase the friction with the welding parts. At the same time, the rubber member is made of a flexible material and has a certain buffering effect, which can reduce the pressure on the welding parts during the downward material collection process.

[0041] refer to Figure 2 and Figure 5 The assembly frame 1 is provided with a slide rail 11 and a slider 12 that cooperate with each other. The slide rail 11 is arranged in the vertical direction. The connecting seat 2 is connected to the slider 12 and moves up and down along the slide rail 11. The suction nozzle body 4 is located below the connecting seat 2, and the driving member 3 is located above the connecting seat 2.

[0042] The driving member 3 includes a telescopic cylinder 31 and a transmission rod 32 , and the telescopic cylinder 32 and the connecting seat 2 are transmitted via the transmission rod 32 .

[0043] In order to prevent the nozzle body from moving downward and exerting excessive pressure on the welding part, causing deformation of the part when it contacts the welding part, in some embodiments, the driving member 3 also includes a buffer spring 33, one end of the buffer spring 33 acts on the transmission rod 32, and the other end acts on the connecting seat 2.

[0044] refer to Figure 5 In some embodiments, the transmission rod 32 is movably connected to the connecting seat 2. When the connecting seat 2 moves downward, the transmission rod 32 acts on the connecting seat 2 through the buffer spring 33 for buffering; when the connecting seat 2 moves upward, one end of the transmission rod 32 directly acts on the connecting seat 2 for driving.

[0045] refer to Figure 5 and Figure 6 In order to limit the travel of the connecting seat 2 on the assembly frame 1, an adjustable limiting structure 13 is provided on the assembly frame 1, and a limiting unit 21 cooperating with the limiting structure 16 is provided on the connecting seat 2.

[0046] Furthermore, the adjustable limiting structure 13 may be a first bolt and a second bolt respectively located at the upper and lower sides of the limiting unit 21. By rotating the first bolt and the second bolt to adjust the distance between the two, the movable range of the limiting unit 21 is controlled to limit the stroke.

[0047] In some embodiments, in order to improve the material taking efficiency, two groups of suction nozzle bodies may be provided on the assembly rack.

[0048] The technical features of the above-mentioned embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification. When the technical features in different embodiments are embodied in the same figure, it can be regarded that the figure also discloses the combination examples of the various embodiments involved.

[0049] The above-mentioned embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
