In other embodiments, the name of the first component 210 is not limited to the body, and the name of the second component 220 is not limited to the back cover. The names of the first component 210 and the second component 220 can be changed according to the actual product name.

[0029] For ease of description, a three-dimensional coordinate system is added for illustration. The X axis is the first direction, the Y axis is the second direction, and the Z axis is the third direction. In this embodiment, the first direction, the second direction, and the third direction are perpendicular to each other. In other embodiments, the relationship between the first direction, the second direction, and the third direction can be adjusted according to the actual structure of the first element 210 and the second element 220.

[0030] The fixture 100 may include a main body 10, a carrier 15, a first clamping assembly 20, a second clamping assembly (not shown), a positioning assembly, a pressing assembly 40, and a vacuum adsorption assembly (not shown). The carrier 15, the first clamping assembly 20, the second clamping assembly, the positioning assembly (not shown), the pressing assembly 40, and the vacuum adsorption assembly may be respectively arranged inside the main body 10 or on the surface of the main body 10.

[0031] The carrier 15 is located on the surface of the main body 10 determined along the X-axis and the Y-axis, and the carrier 15 is used to carry the first element 210. The carrier 15 is provided with a groove 152, and the first element 210 is located in the groove 152. The size of the groove 152 is adapted to the size of the first element 210. The groove 152 is used to limit the first element 210 along the X-axis and the Y-axis, and can prevent the first element 210 from moving in the XY plane (the plane determined by the X-axis and the Y-axis).

[0032] The first clamping assembly 20 includes two first clamping jaws 21, which can move relative to each other to clamp the carrier 15, and are used to fix the carrier 15, thereby preventing the first element 210 from moving relative to the body 10. In this embodiment, the two first clamping jaws 21 can move relative to each other along the X-axis, that is, the two first clamping jaws 21 can clamp the carrier 15 along the X-axis.

[0033] The second clamping assembly (not shown) includes two second clamping jaws (not shown), and the two second clamping jaws can move relative to each other to clamp the second element 220. In this embodiment, the two second clamping jaws can move relative to each other along the Y axis, that is, the two second clamping jaws can clamp the second element 220 along the Y axis. After the second clamping jaw clamps the second element 220, the second element 220 is located on the side of the first element 210 away from the main body 10, and the positions of the second element 220 and the first element 210 are roughly corresponding. After the second clamping jaw clamps the second element 220, the second element 220 is subsequently limited by the joint action of the first clamping assembly 20, the second clamping assembly and the third clamping assembly, so that the positions of the second element 220 and the first element 210 correspond to each other, so as to facilitate subsequent pressing.

[0034] The positioning assembly is used to position the second element 220 so that the second element 220 corresponds to the position of the first element 210 and can temporarily support the second element 220. The positioning assembly may include a plurality of positioning units, which respectively position the second element 220 from different orientations. In this embodiment, the positioning assembly may include a first positioning unit 31, a second positioning unit 33, and a third positioning unit 35.

[0035] The first positioning unit 31 may include a first cylinder 312 and a first pusher 314. The first cylinder 312 is disposed in the main body 10. The first pusher 314 is disposed at one end of the first cylinder 312. The first cylinder 312 allows the first pusher 314 to be retractable along the X-axis so as to abut against one side of the second element 220 along the X-axis. In this embodiment, the first pusher 314 is used to abut against the short side of the second element 220.

[0036] The second positioning unit 33 may include a second cylinder 332 and a second pusher 334. The second cylinder 332 is disposed in the main body 10. The second pusher 334 is disposed at one end of the second cylinder 332. The second cylinder 332 enables the second pusher 334 to be retractable along the Y axis so as to be abutted against one side of the second element 220 along the Y axis. In this embodiment, the second pusher 334 is used to abut against the long side of the second element 220.

[0037] The third positioning unit 35 may include a third cylinder 352 and a third pusher 354, the third cylinder 352 is disposed in the main body 10, and the third pusher 354 is disposed at one end of the third cylinder 352. The third pusher 354 includes a first portion 3542 and a second portion 3544, the first portion 3542 and the second portion 3544 are perpendicular to each other, the first portion 3542 can extend along the X axis, and the second portion 3544 can extend along the Y axis. The third cylinder 352 can make the third pusher 354 extendable along a direction intersecting the X axis and the Y axis and perpendicular to the Z axis, so as to be used to abut against the corner of the second element 220. In this embodiment, the third pusher 354 is used to abut against one of the corners of the second element 220.

[0038] Specifically, the second element 220 is the back cover of the mobile phone, and the second element 220 is a cuboid. The second element 220 includes a first side, a second side, a third side and a fourth side, the first side, the second side, the third side and the fourth side are four sides of a rectangle, the first side and the third side are parallel to each other and are short sides, the second side and the fourth side are parallel to each other and are long sides, the first push head 314 is used to abut against the first side, the second push head 334 is used to abut against the second side, and the third push head 354 is used to abut against the corner formed by the connection of the third side and the fourth side. The first push head 314, the second push head 334 and the third push head 354 work together to limit and fix the second element 220 in advance, so that the position of the second element 220 matches that of the first element 210.

[0039] The pressing assembly 40 may include a bracket 41, a cover plate 42, a handle 43, a fixing member 44, a pressing member 45 and a pressing plate 46. The bracket 41 is fixed to the main body 10 and protrudes from the main body 10 along the Z axis. The cover plate 42 is rotatably arranged on the bracket 41. In this embodiment, the cover plate 42 can rotate along the X axis to the side of the second element 220 away from the first element 210 and parallel to the XY plane. The handle 43 is rotatably arranged on the cover plate 42. The fixing member 44 is fixed to the cover plate 42, and an external force can be applied to the handle 43 so that the handle 43 drives the cover plate 42 to rotate around the X axis. After the handle 43 rotates relative to the cover plate 42, it can overlap the end of the fixing member 44 away from the cover plate 42 for stopping. The pressing member 45 is relatively fixed to the pressing plate 46, and the cover plate 42, the pressing member 45 and the pressing plate 46 can move synchronously with the handle 43. The handle 43 includes a protrusion 432, which extends toward the pressing piece 45. After the handle 43 is rotated to a certain angle, the protrusion 432 contacts the pressing piece 45, driving the pressing piece 45 to move along the Z axis. The pressing plate 46 moves along the Z axis synchronously to adjust the distance between the pressing plate 46 and the second component 220, so that the pressing plate 46 presses the second component 220 onto the first component 210 along the Z axis.

[0040] The vacuum adsorption assembly may include a vacuum pump 51 and a suction cup 53, the vacuum pump 51 is connected to the suction cup 53, the vacuum pump 51 may be located in the main body 10, the suction cup 53 is located on the surface of the pressing plate 46 away from the pressing member 45, and the vacuum pump 51 is used to generate negative pressure on the suction cup 53 so that the suction cup 53 adsorbs the second component 220. After the vacuum pump 51 adsorbs the second component 220, the second clamping jaw, the first push head 314, the second push head 334 and the third push head 354 can release the limiting effect on the second component 220, so that the pressing assembly 40 can move the second component 220 along the Z axis, so as to facilitate the pressing of the second component 220 with the first component 210.

[0041] The fixture 100 may further include a first sensor 61 and a first support frame 60, wherein the first support frame 60 is disposed on the main body 10, and the first sensor 61 is disposed at the end of the first support frame 60 away from the main body 10, and the first sensor 61 is used to sense whether the cover plate 42 is pressed against the first sensor 61. When the cover plate 42 rotates to be parallel to the XY plane, the cover plate 42 may be pressed against the first sensor 61, and the suction cup 53 contacts the second component 220. When the first sensor 61 senses the cover plate 42, the vacuum pump 51 starts to work so that the suction cup 53 absorbs the second component 220. After the suction cup 53 absorbs the second component 220, the second component 220 and the first component 210 may be spaced apart.

[0042] Please combine Figure 3 The pressing assembly 40 may also include a guide rod 47, which is movably arranged inside the fixing member 44. The guide rod 47 protrudes from the end of the fixing member 44 away from the cover plate 42. Before the handle 43 contacts the fixing member 44, it first contacts the guide rod 47 and is pressed against the guide rod 47, so that the guide rod 47 moves relative to the fixing member 44 along the Z-axis direction. The fixture 100 may also include a second sensor 71 and a second support frame 70. The second support frame 70 is arranged on the main body 10. The second sensor 71 is located inside the second support frame 70. The second sensor 71 is used to sense whether the guide rod 47 is pressed against the second sensor 71. When the guide rod 47 is pressed to a certain extent, the guide rod 47 contacts the second sensor 71. When the second sensor 71 senses that the guide rod 47 is pressed against the second sensor 71 for a certain period of time, the vacuum adsorption assembly stops working. Specifically, when the second component 220 contacts the first component 210, the guide rod 47 contacts the second sensor 71, and as the suction cup 53 absorbs the second component 220 and the pressing plate 46 moves along the Z axis to press the second component 220 and the first component 210 together, after the second sensor 71 senses the guide rod 47 for a certain period of time, the vacuum pump 51 stops working and stops the movement of the pressing plate 46. In other embodiments, the second sensor 71 is not limited to being located inside the second support frame 70, and the guide rod 47 is not limited to being set inside the fixing member 44, and the functions of the guide rod 47 and the second sensor 71 can be achieved.

[0043] The third pusher 354 is rotatably disposed on the main body 10, and the included angles between the rotation axis of the third pusher 354 and the X-axis and the Y-axis are both 45°, and the third pusher 354 is perpendicular to the Z-axis, so that the rotation axis of the third pusher 354 can limit the corner of the second element 220. After the limiting effect of the third pusher 354 on the second element 220 is released, the third pusher 354 can be rotated in a direction away from the second element 220 to make the third pusher 354 away from the second element 220. When the pressing assembly 40 is used to press the second element 220, the third pusher 354 can be prevented from interfering with the pressing assembly 40 (such as the cover plate 42, the pressing plate 46, etc.) to affect the operation of the pressing assembly 40.

[0044] See also Figures 4 to 7 , and combined with Figures 1 to 3 The description of the fixture 100 is provided in the figure, and the relationship between the various components in the fixture 100 provided in the embodiment of the present application is further explained through a specific assembly process.

At this time, the first pusher 314, the second pusher 334 and the third pusher 354 make the position of the second component 220 correspond to the position of the first component 210.

[0047] See also Figure 6 Combined with Figures 1 to 3 , applying force to the handle 43, driving the cover plate 42 to rotate around the X axis until it contacts the pressing piece 45. At this time, the cover plate 42 is pressed against the first sensor 61, and the suction cup 53 contacts the second component 220. After the first sensor 61 senses the cover plate 42, the vacuum pump 51 starts working, and negative pressure is generated in the suction cup 53 to adsorb the second component 220. Please refer to Figure 7 Combined with Figures 1 to 3After the suction cup 53 absorbs the second component 220 , the second clamping jaw, the first push head 314 , the second push head 334 and the third push head 354 release the limiting effect on the second component 220 .

[0048] The handle 43 is continuously rotated to press the pressing member 45 along the Z axis, and the pressing member 45 moves along the Z axis, driving the pressing plate 46 to apply a force to the second component 220 along the Z axis, thereby pressing the second component 220 and the first component 210 together to obtain a pressed product. In the process of continuing to rotate the handle 43, the handle 43 presses the guide rod 47, and the guide rod 47 moves and contacts the second sensor 71. After the second sensor 71 senses the guide rod 47, after a certain delay (for example, 1 second), the vacuum pump 51 stops working, releases the suction effect of the suction cup 53 on the second component 220, and stops the pressing plate 46 from continuing to move toward the second component 220 along the Z axis.

[0049] Apply force to the handle 43 again to open the cover 42, and then the assembled product can be obtained.
