[0032] The present invention will be described in detail below in conjunction with the embodiments shown in the accompanying drawings. However, the embodiments do not limit the present invention, and any changes in mechanism, method, or function made by a person skilled in the art based on the embodiments are all within the protection scope of the present invention.

[0033] Terms such as "upper", "lower", "left", "right", "front", "back", etc. used herein to indicate relative positions in space are used for the purpose of convenience to describe the relationship between one feature and another feature as shown in the drawings. It is understood that, depending on the placement of the product 30, the terms of relative positions in space may be intended to include different orientations other than those shown in the drawings, and should not be construed as limitations on the claims. In addition, the descriptor "horizontal" used herein is not completely equivalent to being perpendicular to the direction of gravity, and a certain angle of inclination is allowed.

[0034] like Figure 1-4As shown, an embodiment of the utility model provides a pipe straightening device 100, which is suitable for straightening pipes 301 on certain products 30, such as heat-conducting copper pipes on relays.

[0035] The pipe straightening device 100 comprises a straightening mechanism 10 and a driving mechanism 20 for driving the straightening mechanism 10 to move. The straightening mechanism 10 comprises a connecting seat 1 connected to the driving mechanism 10, a first driving member 2 connected to the connecting seat 1, a fixing assembly 3 and a clamping assembly 4, wherein the fixing assembly 3 is used to fix the product 30, the clamping assembly 4 is movably arranged along a first direction relative to the fixing assembly 3, and the clamping assembly 4 can clamp and release the pipe 301 on the product 30 along a second direction perpendicular to the first direction, and the first driving member 2 is used to drive the clamping assembly 4 to move along the first direction. Figure 1 The X-axis direction is the first direction mentioned above, and the Y-axis direction is the second direction mentioned above.

[0036] When the pipe straightening device 100 is in use, the driving mechanism 20 drives the straightening mechanism 10 to move to the product 30 so that the fixing assembly 3 can fix the product 30. Then, the clamping assembly 4 clamps the pipe 301 along the second direction, and the first driving member 2 drives the clamping assembly 4 clamping the pipe 301 to move along the first direction to straighten the pipe 301. To ensure the straightening effect of the pipe 301, the first driving member 2 can drive the clamping assembly 4 to move back and forth along the first direction to repeat the process of straightening the pipe 301 multiple times.

[0037] The first direction is consistent with the extension direction of the straightened tube 301. Figure 1 As shown, product 30 is a relay ( Figure 1 Only the upper cover of the relay is shown in the figure. Pipe fitting 301 is the heat-conducting copper pipe on the relay. The straightened heat-conducting copper pipe is Figure 1 In the state shown, it needs to extend in the up and down direction. Therefore, in this embodiment, the first direction is Figure 1 In the state shown, it also extends in the up-down direction. In other embodiments, if the straightened pipe 301 needs to extend in other directions, the first direction should also be changed accordingly.

[0038] In this embodiment, the fixing assembly 3 includes a pressing block 31 for pressing the product 30, and a connecting frame 32 connecting the pressing block 31 and the connecting seat 1. The driving mechanism 20 drives the connecting seat 1 to move, which causes the connecting seat 1 to drive the pressing block 31 to move, so that the pressing block 31 can press and fix the product 30 on a platform. A soft cushion made of rubber or silicone or other materials can be provided at the contact part between the pressing block 31 and the product 30 to prevent the product 30 from being crushed.

[0039] In other embodiments, the pressing block 31 may also be replaced by a clamping fixture, which clamps the product 30 from both sides to fix the position of the product 30 .

[0040] In this embodiment, the clamping assembly 4 includes a clamping drive 41, a first clamping member 42 and a second clamping member 43 connected to the clamping drive 41 and arranged opposite to each other along the second direction, a clamping space 5 which is through-shaped in the first direction is formed between the first clamping member 42 and the second clamping member 43, and the pipe 301 can pass through the clamping space 5 along the first direction. The clamping drive 41 is used to drive the first clamping member 42 and the second clamping member 43 to move away from and closer to each other along the second direction to change the size of the clamping space 5.

[0041] When the first clamping member 42 and the second clamping member 43 are close to each other, the clamping space 5 is smaller. At this time, the first clamping member 42 and the second clamping member 43 can contact the outer peripheral surface of the pipe 301 to jointly clamp the pipe 301. When the first clamping member 42 and the second clamping member 43 clamp the pipe 301, the first driving member 2 drives the clamping assembly 4 along the first direction away from the product 30 to straighten the pipe 301. When the second clamping member 43 and the second clamping member 43 are away from each other, the clamping space 5 is larger, and the first clamping member 42 and the second clamping member 43 do not contact the pipe 301. In this way, the first driving member 2 can drive the clamping assembly 4 from a position away from the product 30 to a position close to the product 30 along the first direction to straighten the pipe 301 again.

[0042] The first clamping member 42 includes a first connection block 421 connected to the clamping driving member 41, a first roller 422 rotatably connected to the first connection block 421 around its own axis, and the second clamping member 43 includes a second connection block 431 connected to the clamping driving member 41, and a second roller 432 rotatably connected to the second connection block 431 around its own axis. The axes of the first roller 422 and the second roller 432 are both perpendicular to the first direction, and the clamping space 5 is formed between the outer circumference of the first roller 422 and the outer circumference of the second roller 432. With the above arrangement, the clamping driving member 41 can drive the first roller 422 and the second roller 432 to move closer and farther. When the first roller 422 and the second roller 432 are close to each other, they clamp the pipe 301 together, and the first roller 422 and the second roller 432 are both rotatably arranged around their own axes. In this way, when straightening the pipe 301, the friction between the pipe 301 and the first roller 422 and the second roller 432 is small.

[0043] In this embodiment, one first roller 422 is provided, two second rollers 432 are provided, and the axis of each second roller 432 is arranged at an acute angle with the axis of the first roller 422, so that when the pipe 301 passes through the clamping space 5, the first roller 422 and the two second rollers 432 are distributed around the pipe 301, which can effectively clamp the pipe 301, and the clamping assembly 4 can also adapt to clamping pipes 301 of different diameters. When the clamping assembly 4 clamps the pipe 301, the first driving member 2 drives the clamping assembly 4 to move along the first direction, and the one first roller 422 and the two second rollers 432 will rotate around their own axes due to friction with the pipe 301, thereby dynamically straightening the pipe 301 to avoid damage to the pipe 301.

[0044] Further, the first roller 422 includes a first roller body 4221, a first annular groove 4222 formed by a concave formation on the outer circumference of the first roller body 4221, the first annular groove 4222 and the first roller body 4221 are coaxially arranged, and the depth and width of the first annular groove 4222 are arranged in inverse proportion, that is, the deeper the depth of the first annular groove 4222, the smaller its width. When the first roller 422 and the two second rollers 432 clamp the pipe 301, the two second rollers 432 press part of the pipe 301 into the first annular groove 4222 to effectively limit the position of the pipe 301, and the cross-section of the first annular groove 4222 is roughly V-shaped or trapezoidal, which can adapt to pipes 301 of different diameters.

[0045] In other embodiments, only one second roller 432 may be provided, and the structure may be the same as that of the first roller 422, that is, the second roller 432 includes a second roller body, a second annular groove formed by a recessed outer peripheral surface of the second roller body, the second annular groove and the second roller body are coaxially arranged, and the depth and width of the second annular groove are inversely proportional.

[0046] In this embodiment, the driving mechanism 20 includes a support 21 and a second driving member 22, the connecting seat 1 is movably connected to the support 21 along a first direction, and the second driving member 22 connects the support 21 and the connecting seat 1, so as to drive the connecting seat 1 to move along the first direction relative to the support 21. When the pipe straightening device 100 is used to straighten the pipe 301 on the product 30, the product 30 is placed on one side of the fixing component 3 in the first direction, and the second driving member 22 drives the connecting seat 1 to move along the first direction, which can drive the fixing component 3 to move to the product 30, so that the fixing component 3 can fix the product 30.

[0047] Further, the support 21 includes a bottom plate 211, a connecting plate 212 spaced apart from the bottom plate 211 in the first direction, and a connecting piece 213 connecting the bottom plate 211 and the connecting plate 212, and the connecting seat 1 is connected to the connecting plate 212. The pipe straightening device 100 can be fixed on a certain table through the bottom plate 211, and the connecting piece 213 and the connecting plate 212 set the straightening mechanism 10 at a certain height so that there is enough space under the straightening mechanism 10 to place the product 30. A plurality of connecting holes can be opened on the bottom plate 211 so that the bottom plate 211 can be fixed to a certain table through fasteners such as screws.

[0048] In this embodiment, the first driving member 2 and the second driving member 22 are telescopic cylinders, and the clamping driving member 41 is a clamping claw cylinder. All three can be driven and controlled by an air source and an electromagnetic valve. The pipe straightening device 100 does not need to be equipped with other power providing elements.

[0049] The utility model also provides a relay assembly device, which includes a conveying device for conveying relays and a pipe straightening device 100 arranged on one side of the conveying device. After the relay is conveyed by the conveying device to the pipe straightening device 100, the pipe straightening device 100 straightens the copper tube on the relay to facilitate the subsequent manufacturing process of the relay.

[0050] To sum up, in the pipe straightening device 100 and relay assembly equipment provided by the utility model, the driving mechanism 20 drives the straightening mechanism 10, so that the straightening mechanism 10 can actively move to the product. When the straightening mechanism 10 straightens the pipe 301 on the product 30, the product 30 is first fixed by the fixing component 3, and then the pipe 301 on the product 30 is straightened. The pipe straightening device 100 has a compact structure as a whole and occupies a small space.
