In order to solve the above-mentioned problems, the present invention provides an alignment assembly device 1000, and fig. 1 to 13 are specific embodiments of the alignment assembly device 1000 provided by the present invention.

Referring to fig. 1 to 2, the alignment assembly device 1000 includes an assembly pressure maintaining mechanism 100 and an alignment mechanism 200, wherein the assembly pressure maintaining mechanism 100 includes a mounting base 1, and two fixing portions provided on the mounting base 1 and corresponding to the housing 2000 and the light guide column 3000, and at least one of the fixing portions is movably disposed in a first direction, a second direction and a third direction, so that the mounting hole on the housing 2000 on the two fixing portions and the light guide column 3000 can be close to and far away from each other in the first direction, and the opposite position is adjusted in the second direction and the third direction; the alignment mechanism 200 includes a position detecting device 10, where the position detecting device 10 is configured to detect the centering of the center of the light guide column 3000 and the center of the mounting hole on the housing 2000 in the second direction and the third direction.

In the technical scheme provided by the invention, two fixing parts are arranged on the mounting seat 1, one fixing part is used for fixing the shell 2000, the other fixing part is used for fixing the light guide column 3000, at least one fixing part of the two fixing parts can be movably arranged in the first direction, the second direction and the third direction, the center of the light guide column 3000 and the center of the mounting hole can be aligned by adjusting the movably arranged fixing parts along the second direction and the third direction, the position detection device 10 can detect the centering degree of the center of the light guide column 3000 and the center of the mounting hole on the shell 2000 in the second direction and the third direction, after detecting that the center of the light guide column 3000 and the center of the mounting hole on the shell 2000 are aligned, the fixing part which can move along the first direction is adjusted, so that the light guide column 3000 can be accurately mounted into the mounting hole, and the position detection device can be accurately assembled with the inner wall of the shell 2000 due to the fact that the diameter of the light guide column 3000 is slightly smaller than the diameter of the mounting hole, and the position detection device 3000 is close to the mounting hole in the shell 2000, and the accurate alignment risk of the mounting hole and the crack can be avoided, and the alignment process can be realized.

Specifically, in this embodiment, the position detecting apparatus 10 includes an image capturing system 101, where the image capturing system 101 is configured to capture images of the light guiding column 3000 and the mounting hole on the housing 2000, and in order to facilitate real-time observation by an operator, the position detecting apparatus 10 further includes a display device 102, where the display device 102 is configured to display the images captured by the image capturing system 101 in an enlarged manner.

Further, the two fixing portions are adjusted in the first direction, the second direction and the third direction, so that interference between the light guide column 3000 and the housing 2000 is not guaranteed, when the light guide column 3000 is assembled on the housing 2000, a distance between the outer end surface of the light guide column 3000 and the outer end surface of the housing 2000 is required to be controlled between +0.04mm and-0.1 mm, that is, a length of the outer end surface of the light guide column 3000 protruding out of the outer end surface of the housing 2000 cannot be greater than 0.04mm, a distance between the outer end surface of the light guide column 3000 lower than the outer end surface of the housing 2000 cannot be greater than 0.1mm, and therefore, the positioning of the light guide column 3000 in the first direction is required to be controlled, and a distance between the outer end surface of the light guide column 3000 and the outer end surface of the housing 2000 is required to be controlled between +0.04mm and-0.1 mm, so in this embodiment, the assembling mechanism 100 further includes a level portion 3, and the level portion 3 is used for being attached to the outer end surface of the housing 2000 and corresponding to the housing 2000, and the first side of the light guide column 3000 is arranged along the first direction. So, after the flush part 3 is close to the outer end face of the housing 2000, when the light guide column 3000 moves along the first direction, the light guide column 3000 is propped against the flush part 3, at this time, the outer end face of the light guide column 3000 and the flush part 3 are close to the close surface of the housing 2000, that is, the outer end face of the light guide column 3000 is substantially flush with the outer end face of the housing 2000, so that the light guide column 3000 protrudes from the outer end face of the housing 2000, and the distance between the light guide column 3000 and the outer end face of the housing 2000 in the first direction is always controlled between +0.04mm and-0.1 mm.

Specifically, the flush part 3 includes a flush plate 31, a first elastic member 32, and a holding head 33, where the holding head 33 is movably mounted on the flush plate 31 through the first elastic member 32, and the holding head 33 is configured to be disposed corresponding to the mounting hole so as to abut against an outer end surface of the housing 2000. It should be noted that, the elastic coefficient of the first elastic member 32 may be set to be smaller, so that the first elastic member 32 can be deformed slightly while the light guiding column 3000 abuts against the abutment head 33, but the light guiding column 3000 can be controlled within a set accuracy range.

Further, in order to avoid interference between the flush part 3 and the housing 2000 when the housing 2000 is fixed to the corresponding fixing part, and to affect the convenience of fixing the housing 2000 to the fixing part, in this embodiment, the flush part 3 is rotatably mounted on the mounting seat 1, the flush part 3 has a first working position for abutting against an outer end surface of the housing 2000 in a rotation stroke thereof, when the housing 2000 needs to be mounted and fixed, the flush part 3 is rotatably opened, and after the housing 2000 is fixed, the flush part 3 is rotated to the first working position, so that the flush part 3 abuts against the outer end surface of the housing 2000.

It should be noted that, since the light guide column 3000 needs to stand for a certain time to maintain pressure after being assembled, after the adhesive on the light guide column 3000 is firmly fixed to the housing 2000, the housing 2000 to which the light guide column 3000 is adhered can be taken down from the corresponding fixing portion, in order to avoid affecting the assembly process, the assembly pressure maintaining mechanism 100 may be provided with a plurality of units, after the assembly pressure maintaining mechanism 100 completes the assembly, in the previous stage of the pressure maintaining process, the assembly pressure maintaining mechanism 100 may be moved to another place on the alignment mechanism 200, and the next housing 2000 and the light guide column 3000 are assembled in an aligned manner.

Therefore, in this embodiment, the alignment mechanism 200 further includes a base 20, the assembly and pressure maintaining mechanism 100 is detachably mounted on the base 20, in order to ensure that, in each of the assembly and pressure maintaining mechanisms 100, the flush part 3 is capable of achieving assembly and pressure maintaining in the working first position, so the alignment mechanism 200 further includes a foolproof mechanism 30, where the foolproof mechanism 30 is used to ensure that, after the housing 2000 is fixedly mounted on the fixing part, the flush part 3 is rotated to the first working position, the foolproof mechanism 30 includes a movably disposed limit part 301, where the limit part 301 has a limit position and a yielding position in a movable stroke thereof, and the assembly and pressure maintaining mechanism 100 is fixedly limited in the base 20. Thus, after the assembly pressure maintaining mechanism 100 is placed on the base 20, the limiting portion 301 moves to the limiting position, so that the assembly pressure maintaining mechanism 100 is fixed on the base 20, if the flush portion 3 is not located at the first working position, the limiting portion 301 is always located at the limiting position, and when an operator needs to remove the assembly pressure maintaining mechanism 100 to rest, the assembly pressure maintaining mechanism 100 cannot be detached, so that the operator is reminded of rotating the flush portion 3 to the first working position, and therefore, the light guide column 3000 can be ensured to be installed at the set position.

The fool-proof means may be implemented by a structure in which, in this embodiment, the alignment assembly device 1000 further includes a conducting structure 300 and a control device, the conducting structure 300 is disposed corresponding to the level portion 3, that is, when the level portion 3 rotates to the first working position, the state of the conducting structure 300 is changed, and the control device controls, through the state of the conducting structure 300, whether the limiting portion 301 is in the limiting position or in the yielding position. Specifically, the conducting structure 300 includes a first conducting portion 310 that is movably disposed, the first conducting portion 310 has a conducting position and a disconnecting position in an active stroke, when the flush portion 3 is not in the first working position, the first conducting portion 310 is in the conducting position, in the stroke of the flush portion 3 rotating to the first working position, the flush portion 3 drives the first conducting portion 310 to switch from the conducting position to the disconnecting position, because the control device is electrically connected with the conducting structure 300 and the fool-proof mechanism 30, when the first conducting portion 310 switches to the disconnecting position, it is indicated that the flush portion 3 is already in the first working position, and when the light guide column 3000 is assembled, the end face of the light guide column 3000 will abut against the flush portion 3, so that the light guide column 3000 reaches the preset position for installation, at this time, the control device controls the fool-proof mechanism 30 to switch to the yielding position, and when the assembling mechanism 100 is completed, the assembling mechanism 100 can be assembled and disassembled and removed from the moving mechanism.

Further, in order to facilitate the turning on of the conducting structure 300 from the off state to the on position again and automatically when the flush part 3 is turned on at the first station position, and facilitate the next normal operation, in this embodiment, the conducting structure 300 further includes a reset element 320, where the reset element 320 is configured to reset the first conducting part 310 from the off position to the on position.

Specifically, in this embodiment, the reset element 320 includes a spring, the conducting structure 300 further includes a base 330 and two second conducting portions 340, the base 330 is disposed on the mounting base 1, and the first conducting portion 310 is movably mounted on the base 330 through the spring; the two second conducting portions 340 are separately disposed at intervals on two sides of the first conducting portion 310 in the moving direction, when the first conducting portion 310 moves to the conducting position, the first conducting portion 310 conducts the two conducting portions, and when the first conducting portion 310 moves to the disconnecting position, the first conducting portion 310 is far away from the two conducting portions, so that the two second conducting portions 340 are disconnected.

More specifically, the mounting seat 1 is provided with a mounting groove, the spring is disposed in the mounting groove, the first conducting portion 310 is mounted in the mounting groove through the spring, when the first conducting portion 310 is at the conducting position, the outer end portion of the first conducting portion 310 protrudes out of the notch of the mounting groove, two first contact portions are protruding on the side portion of the first conducting portion 310, two second conducting portions 340 are disposed on two opposite side walls of the mounting groove, two second contact portions are disposed on two sides of the two second conducting portions 340, which are close to each other, respectively, when the flush portion 3 is far away from the conducting structure 300, the spring is in a compressed state, two first contact portions of the first conducting portion 310 are respectively in contact with the two second contact portions, when the flush portion 3 is close to the conducting structure 300, the two first conducting portions 310 are gradually contacted, when the first conducting portion 310 moves towards the groove bottom, the two second contact portions are further contacted by the two first contact portions 340, and the two first contact portions are gradually separated from the two first contact portions.

Specifically, in order to achieve automatic control, in this embodiment, the limiting portion 301 is disposed at intervals from the base 20 in the first direction, and the limiting portion 301 is movably disposed along the second direction; it may be appreciated that when the mounting base 1 is placed on the base 20 and the limiting portion 301 is at the limiting position, the mounting base 1 is located between the limiting portion 301 and the base 20, and when the assembly pressure maintaining mechanism 100 needs to be moved, the assembly pressure maintaining mechanism 100 is moved along the first direction, and at this time, the limiting portion 301 limits the movement of the mounting base 1. In order to achieve automatic limiting, in this embodiment, the fool-proof mechanism 30 further includes a first driving device 302 disposed on the base 20, where the first driving device 302 has a first driving portion that moves along the second direction, and the first driving portion is connected to the limiting portion 301 to drive the limiting portion 301 to move along the first direction; the control device is electrically connected to the first driving device 302, and is used for controlling the first driving device 302 to work. In this way, when the flush part 3 is located at the first working position, the on structure 300 is in an off state, and when the control device receives the off information, the first driving device 302 is controlled to work, so that the limit part 301 moves from the limit position to the yielding position.

The first driving device 302 may be an air cylinder, and an air cylinder rod of the air cylinder is provided as the first driving portion, however, the first driving device 302 may be a ball screw structure or the like in addition to the air cylinder, and the specific form of the first driving device 302 is not particularly limited in the present invention.
