[0023] In the description of the present application, it should be understood that if the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. appear, the orientation or position relationship indicated by these terms is based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.

[0024] In addition, if the terms "first" or "second" appear, these terms are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of this application, if the term "plurality" appears, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0025] In this application, unless otherwise clearly specified and limited, if the terms "installed", "connected", "connected", "fixed" and the like appear, these terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0026] In the present application, unless otherwise clearly specified and limited, if there is a description that a first feature is "above" or "below" a second feature, etc., or similar descriptions appear, it may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature being "above", "above" and "above" the second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. The first feature being "below", "below" and "below" the second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0027] It should be noted that if an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. If an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. If any, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in this application are for illustrative purposes only and do not represent the only implementation method.

[0028] The current connector has a long strip-shaped outer contour, and the various parts included therein also have corresponding tubular or columnar shapes. For example, as shown in Figures 1 and 2, the connector may include an inner shell 21, a middle piece 22, and an outer shell 23 that are sequentially sleeved from the inside to the outside. Therefore, the assembly can be completed by successively sleeved the middle piece 22 and the outer shell 23 on the inner shell 21 (here refers to the assembly of the three). However, when there is an axial misalignment between the three, simple axial plug-in is often difficult to effectively achieve sleeve assembly. Among them, the problem of misalignment mostly occurs when the outer shell 23 is assembled, that is, the outer shell 23 and the middle piece 22 are misaligned. Simply put, when assembling the outer shell 23, the inner shell 21, as the innermost component, can often be fixed by a jig. As for the middle piece 22, it is sleeved on the inner shell 21 and the outer shell 23 is sleeved on the outside. If there is a certain amount of movable space between the middle piece 22 and the inner shell 21, the middle piece 22 is prone to deflection, resulting in misalignment between the middle piece 22 and the inner hole 24 of the outer shell 23. Therefore, when the outer shell 23 is press-fitted, there is a problem that the end face of the outer shell 23 abuts against the middle piece 22 and cannot be installed smoothly.

[0029] In order to solve the above problems, the present application provides a crimping device, which includes a centering assembly. During press-fitting, the centering assembly can embrace the outer periphery of the middle piece to position the middle piece, align the middle piece with the inner hole of the outer sleeve, and improve the smoothness of axial press-fitting. The axial direction described in each embodiment of the present application can be parallel to the press-fitting direction mentioned below, and the axial direction is shown by the number O in Figure 1. The crimping device provided in each embodiment of the present application and the assembly equipment including the crimping device are described in detail below in combination with the drawings and specific implementation methods of the specification.

[0030] Referring to FIGS. 1 to 3 , an assembly device 10 provided in one embodiment of the present application is used to assemble a workpiece 20, and the workpiece 20 includes an inner shell 21, a middle piece 22, and an outer shell 23 that are sequentially sleeved from the inside to the outside. The assembly device 10 includes a crimping device 11 and a carrier 12, the carrier 12 is used to place the inner shell 21 sleeved with the middle piece 22, and the crimping device 11 is used to press the outer shell 23 onto the outer periphery of the middle piece 22, so that the inner shell 21, the middle piece 22, and the outer shell 23 are sequentially sleeved from the inside to the outside. It can be understood that the assembly device 10 can assemble the entire workpiece 20, and the crimping device 11 provided in each embodiment of the present application mainly focuses on the press-fitting of the outer shell 23. That is, before the crimping device 11 presses the outer shell 23, the semi-finished workpiece 20 has been assembled by other devices included in the assembly device 10 to form a state as shown in FIG. 2 (i.e., the state in which the middle piece 22 is sleeved on the inner shell 21).

[0031] Please refer to FIG3 . An embodiment of the present application provides a crimping device 11 , which includes a material moving component 100 and a centering component 200 . The material moving component 100 includes a first clamping jaw 110 , which can move between a material picking position and a press-fitting position. The first clamping jaw 110 at the material picking position is used to pick up the outer sleeve 23 ; the first clamping jaw 110 at the press-fitting position is used to move toward the inner shell 21 to press-fit the outer sleeve 23 onto the inner shell 21 with the middle piece 22 . The centering component 200 includes a second clamping jaw 210 , which can be clamped and opened. When clamped, the second clamping jaw 210 can hold the outer periphery of the middle piece 22 , so that along the press-fitting direction K of the first clamping jaw 110 , the middle piece 22 is aligned with the inner hole 24 of the outer sleeve 23 .

[0032] In the above-mentioned crimping device 11, the second clamping jaw 210 can hold the outer periphery of the middle piece 22 sleeved on the inner shell 21 when clamped, so that the middle piece 22 and the inner hole 24 of the outer shell 23 are aligned along the press-fitting direction K of the first clamping jaw 110, thereby improving the alignment accuracy when the outer shell 23 and the middle piece 22 are axially sleeved and assembled. Therefore, when the material transfer assembly 100 drives the outer shell 23 to be press-fitted, it can be conveniently sleeved on the inner shell 21 and the middle piece 22, thereby improving the smoothness of the press-fitting.

[0033] It should be noted that the above example uses the existence of a movable space between the middle piece 22 and the inner shell 21 to illustrate the reason why the middle piece 22 may be misaligned, but there may be many reasons for the misalignment of the middle piece 22, such as the middle piece 22 itself being deformable, etc. The embodiments of the present application do not limit the reasons for the misalignment between the middle piece 22 and the outer shell 23. The crimping device 11 provided in the embodiments of the present application can cope with various misalignment situations of the middle piece 22.

[0034] Regarding the centering assembly 200, it can be understood that if the outer shell 23 is assembled in place and a part of the middle piece 22 is still exposed from the outer shell 23, the second clamping jaw 210 can be held in the area of ​​the middle piece 22 exposed from the outer shell 23 to reduce interference with the press-fitting process of the outer shell 23. Alternatively, the second clamping jaw 210 can be configured to have a sufficiently small thickness dimension so that the second clamping jaw 210 can be accommodated between the middle piece 22 and the outer shell 23. When the outer shell 23 is assembled in place, the second clamping jaw 210 can be pulled out from the outer shell 23.

[0035] Alternatively, in one embodiment, at least in one stage of the movement of the first clamping jaw 110 along the press-fitting direction K, the second clamping jaw 210 moves in a direction away from the first clamping jaw 110 to reduce interference with the movement of the first clamping jaw 110 driving the outer sleeve 23 to be press-fitted. For example, when the first clamping jaw 110 is press-fitted to the position where a partial area of ​​the outer sleeve 23 is sleeved on the middle piece 22, the second clamping jaw 210 moves in a direction away from the first clamping jaw 110 along the press-fitting direction K to avoid the first clamping jaw 110. Since a part of the structure of the middle piece 22 has entered the inner hole 24 of the outer sleeve 23, the outer sleeve 23 can be completely sleeved outside the middle piece 22 by gradually pressing down along the outer periphery of the middle piece 22. Therefore, at this time, the second clamping jaw 210 has almost completed the centering task, so the second clamping jaw 210 is driven to be pressed down as well, which can avoid the first clamping jaw 110 and provide space for the sleeve 23 to be sleeved.

[0036] Please refer to FIG. 3 and FIG. 4. In one embodiment, the material moving assembly 100 includes a first longitudinal moving unit 120, which is connected to the first clamping jaw 110 to drive the first clamping jaw 110 in the press-fitting position to move along the press-fitting direction K. The centering assembly 200 includes a second longitudinal moving unit 220, which is connected to the second clamping jaw 210, and the second longitudinal moving unit 220 can also drive the second clamping jaw 210 to move along the press-fitting direction K. When the first clamping jaw 110 is press-fitted to the position where a partial area of ​​the outer sleeve 23 is sleeved on the middle piece 22, the second longitudinal moving unit 220 drives the second clamping jaw 210 to move along the press-fitting direction K in a direction away from the first clamping jaw 110, so as to provide space for the downward pressing and sleeve action of the outer sleeve 23.

[0037] Further, when the first clamping jaw 110 is pressed to the position where a partial area of ​​the outer sleeve 23 is sleeved on the middle piece 22, the second longitudinal movement unit 220 drives the second clamping jaw 210 to move synchronously with the first clamping jaw 110. It can be understood that the first clamping jaw 110 clamps the outer sleeve 23 and presses it from top to bottom, that is, the first clamping jaw 110 is located above the second clamping jaw 210 along the press-fitting direction K. Therefore, the second clamping jaw 210 is configured to move synchronously with the first clamping jaw 110, and the second clamping jaw 210 can always pass through each local area in the axial direction of the middle piece 22 before the first clamping jaw 110 to position it, improve the alignment accuracy of each local area with the inner hole 24 of the outer sleeve 23, and reduce the probability of the middle area or the tail end area of ​​the middle piece 22 and the outer sleeve 23 being stuck and hindering the assembly.

[0038] In one embodiment, the outer shell 23, the middle piece 22 and the inner shell 21 can be coaxially connected. At this time, the centering positioning of the middle piece 22 by the second clamping jaw 210 is to push the middle piece 22 to be coaxially arranged with the outer shell 23 located at the press-fitting position. Please refer to Figures 3 to 5. In one embodiment, the first clamping jaw 110 has a clamping hole 111, and the second clamping jaw 210 has a centering hole 210a, and the centering hole 210a is coaxially arranged with the clamping hole 111 at the press-fitting position. Therefore, after the second clamping jaw 210 is clamped, the middle piece 22 can be coaxially arranged with the outer shell 23 located at the press-fitting position. It should be noted that when the outer shell 23 and the middle piece 22 have other positional relationships, the relationship between the centering hole 210a and the clamping hole 111 can be adjusted accordingly, so that the second clamping jaw 210 can always push the middle piece 22 to align.

[0039] Please refer to FIG. 4 and FIG. 5 . In one embodiment, the second clamping jaw 210 includes two jaws 210b, which can move toward each other to clamp and embrace the outer periphery of the intermediate member 22. The two jaws 210b are provided with an arc-shaped wall on one side facing each other. When the two jaws 210b are clamped, the two arc-shaped walls are spliced ​​to form a closed centering hole 210a. Therefore, all areas of the inner wall of the centering hole 210a can position the intermediate member 22, thereby improving the positioning effect.

[0040] In one embodiment, the carrier 12 can carry multiple inner shells 21 and middle pieces 22. The first clamp 110 can clamp multiple outer shells 23 at the same time, and the second clamp 210 can position multiple middle pieces 22 at the same time. Therefore, the first clamp 110 can press down to simultaneously press-fit multiple outer shells 23, thereby improving efficiency.

[0041] Please refer to Figures 3 to 5. In one embodiment, the material moving assembly 100 further includes a first clamping unit 130, which is connected to the first clamping jaw 110, and the first clamping unit 130 is used to drive the first clamping jaw 110 to open and clamp. The centering assembly 200 further includes a second clamping unit 230. The second clamping jaw 210 includes a first clamping portion 211 and a second clamping portion 212, and the first clamping portion 211 and the second clamping portion 212 are movable along a first direction S1. The second clamping unit 230 is connected to the first clamping portion 211 and the second clamping portion 212 respectively, and the second clamping unit 230 can drive the first clamping portion 211 and the second clamping portion 212 to move in directions close to and away from each other, so that the second clamping jaw 210 is opened and clamped.

[0042] The first clamping part 211 is provided with a plurality of first claws 213 arranged at intervals along the first direction S1, and the second clamping part 212 is provided with a plurality of second claws 214 arranged at intervals along the first direction S1. Along the first direction S1, the first claws 213 and the second claws 214 are alternately arranged at intervals, and a first claw 213 and a second claw 214 adjacent thereto cooperate to clamp the intermediate member 22. That is, a first claw 213 and a second claw 214 adjacent thereto cooperate to form a pair of centering holes 210a, and a plurality of first claws 213 correspond one by one to a plurality of second claws 214 to form a plurality of centering holes 210a. Thus, when the first clamping part 211 and the second clamping part 212 move toward or away from each other, the plurality of first claws 213 and the plurality of second claws 214 can be opened and clamped synchronously. It can be understood that any first claw 213 and any second claw 214 can be provided with an arc wall as described above.

[0043] Please refer to FIG. 4 . In one embodiment, the second clamping unit 230 is connected to the second longitudinal movement unit 220 . The second longitudinal movement unit 220 is used to drive the second clamping unit 230 and the second clamping jaw 210 to move along the press-fitting direction K.

[0044] Please refer to Fig. 3. In one embodiment, the material moving assembly 100 further includes a material moving driving unit 140, which is connected to the first clamping jaw 110. The material moving driving unit 140 is used to drive the first clamping jaw 110 to move between the material picking position and the press-fitting position. Further, the material moving driving unit 140 can be connected to the first longitudinal moving unit 120 to drive the first longitudinal moving unit 120 and the first clamping jaw 110 to move between the material picking position and the press-fitting position along the second direction S2.

[0045] Please refer to FIG6 . In one embodiment, the crimping device 11 further includes a feeding assembly 300, which is used to feed the outer jacket 23. The orthographic projection of the second clamping jaw 210 in the material picking position along the pressing direction K overlaps with the feeding assembly 300 to pick up the outer jacket 23. With such a configuration, the movement of the second clamping jaw 210 along the pressing direction K can be used not only to press the outer jacket 23, but also to pick up the outer jacket 23.

[0046] Please continue to refer to FIG. 6. In one embodiment, the feed assembly 300 includes a track 310 and a lifting platform 320. The track 310 can be extended along the second direction S2, and the lifting platform 320 is arranged at one end of the track 310. The track 310 is provided with a feed channel 311 extending along the second direction S2, and the feed channel 311 is used to transport the jacket 23. In other words, the feed assembly 300 can transport the jacket 23 along the second direction S2. In the direction perpendicular to the second direction S2, at least part of the area of ​​the feed channel 311 is closed relative to the outside to improve the stability of the workpiece 20 being transported and reduce external interference. Of course, the present application can also set the feed channel 311 to have a connecting seam 312 connected to the outside. When the feed channel 311 is blocked, the dredging tool can be extended into the feed channel 311 through the connecting seam 312 to perform the dredging operation. The lifting platform 320 is provided with an open material taking position 321. The lifting platform 320 is located at one end of the feeding channel 311. The material taking position 321 is used to receive the outer jacket 23 outputted from the feeding channel 311, that is, the feeding channel 311 is used to transport the outer jacket 23 to the material taking position 321 of the lifting platform 320. The lifting platform 320 can lift the outer jacket 23 located at the material taking position 321 toward the side close to the material moving assembly 100 along the direction perpendicular to the second direction S2, and block the feeding channel 311. Since the lifting platform 320 is openly arranged, the first clamp 110 can conveniently pick up the outer jacket 23 located at the material taking position 321. In addition, the lifting platform 320 can lift the workpiece 20 located at the material taking position 321 and block the feeding channel 311, so as to prevent the outer jacket 23 in the feeding channel 311 from being continuously transported outward, which causes the position of the outer jacket 23 at the material taking position 321 to be unstable.

[0047] Please refer to Figure 6. In one embodiment, the feeding assembly 300 includes a lifting drive unit 330, which is connected to the lifting platform 320 to drive the lifting platform 320 to lift along the pressing direction K, so that the lifting platform 320 rises to a position to block the feeding channel 311 and drives the workpiece 20 located at the material picking position 321 to lift.

[0048] In one embodiment, the material conveying assembly 300 may further include a material conveying drive unit (not shown, the same below), which is used to drive the outer shell 23 to be conveyed along the material conveying channel 311, and the material conveying drive unit may be disposed at one end of the track 310 away from the lifting platform 320. For example, the material conveying drive unit may be configured as a vibration plate.

[0049] In one embodiment, the second clamping unit 230, the first longitudinal movement unit 120, the second longitudinal movement unit 220, the material transfer drive unit 140 and the lifting drive unit 330 can be driven by linear drive methods such as cylinders, hydraulic cylinders, electric push rods and pneumatic slides, which are not limited in the various embodiments.

[0050] In one embodiment, the crimping device 11 further includes a first support 400 and a second support 500, the material moving assembly 100 is disposed on the first support 400, and the centering assembly 200 is disposed on the second support 500. In one embodiment, the first support 400 and the second support 500 can be integrally arranged to form a base (not shown, the same below), and the material moving assembly 100 and the centering assembly 200 are both disposed on the base.

[0051] In one embodiment, the assembly equipment 10 includes a transport device (not shown in the figure, the same below), which is connected to the carrier 12 and can drive the carrier 12 to move so as to switch the carrier 12 at the centering component 200.

[0052] It should be noted that the second longitudinal movement unit 220 can not only drive the second clamping jaw 210 to press down to avoid the first clamping jaw 110, but also drive the second clamping jaw 210 to lift up to avoid the assembled workpiece 20, so as to facilitate the switching of the carrier 12. The first longitudinal movement unit 120 is similar, and the first longitudinal movement unit 120 can drive the first clamping jaw 110 to lift up.

[0053] An embodiment of the present application further provides a press-fitting method, which can be used for the press-fitting device 11 and the assembly device 10 described in each embodiment. The press-fitting method includes:

[0054] S1, driving the first clamping jaw 110 to move the outer sleeve 23 to the press-fitting position. As mentioned above, the first clamping jaw 110 can be driven to move by the material transfer driving unit 140 to drive the outer sleeve 23 to move to the press-fitting position.

[0055] S2, driving the second clamping jaw 210 to clamp the middle piece 22 sleeved on the inner shell 21, so that the middle piece 22 and the inner hole 24 of the outer shell 23 are longitudinally aligned.

[0056] S3, driving the first clamping jaw 110 located at the press-fitting position to press down in the longitudinal direction, so that the outer sleeve 23 is put on the outside of the middle piece 22.

[0057] In the above press-fitting method, the middle piece 22 is clamped by the second clamping jaws 210 before the outer sleeve 23 is press-fitted, so that the middle piece 22 is positioned to align with the inner hole 24 of the outer sleeve 23, which can facilitate the press-fitting of the outer sleeve 23.

[0058] In one embodiment, after driving the second clamping jaw 210 to clamp the middle piece 22 sleeved outside the inner shell 21, the press-fitting method further includes:

[0059] S4, when the first clamping jaw 110 is pressed to the position where the partial area of ​​the outer sleeve 23 is covered on the middle piece 22, the second clamping jaw 210 is driven to be pressed down synchronously with the first clamping jaw 110. Thus, the second clamping jaw 210 can provide space for the first clamping jaw 110 to be pressed down. Moreover, the first clamping jaw 110 and the second clamping jaw 210 are pressed down synchronously, and the second clamping jaw 210 can always pass through each local area in the axial direction of the middle piece 22 before the first clamping jaw 110 to position it, improve the alignment accuracy of each local area with the inner hole 24 of the outer sleeve 23, and reduce the probability of the middle area or the tail end area of ​​the middle piece 22 and the outer sleeve 23 being stuck and hindering the assembly.

[0060] In one embodiment, when the outer sleeve 23 is assembled in place, the press-fitting method further comprises:

[0061] S5, driving the first clamping jaw 110 to open.

[0062] S6, driving the second clamping jaw 210 to open.

[0063] S7, driving the first clamping jaw 110 to lift up.

[0064] S8, driving the second clamping jaw 210 to lift up.

[0065] S9, driving the first clamping jaw 110 to move to the material picking position to pick up the outer sleeve 23 to be assembled.

[0066] S10 , driving the carrier 12 to move to switch another carrier 12 to move to the centering assembly 200 .

[0067] The outer sleeve 23 can be continuously assembled by repeating the above steps S1 to S10.

[0068] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described 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.

[0069] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, 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. Therefore, the protection scope of the patent application shall be subject to the attached claims.
