Therefore, the glue accommodating member 22 can rotate without manual operation, the automation degree of the glue dispensing assembly 20 is improved, and the glue dispensing efficiency can be improved. When the driving motor 25 controls the glue accommodating part 22 to rotate, the rotation accuracy of the glue accommodating part 22 can be ensured, so that the smooth part of the surface of the bonding glue in the glue accommodating part 22 can be fully utilized, and more lenses can be uniformly coated with the bonding glue when the areas of the bonding glue in the glue accommodating part 22 are the same.

That is, the glue container 22 is rotatably mounted in the mounting hole through the rotating shaft 222, and the rotating shaft 222 can extend into the containing cavity 214 to be connected with the transmission member, so that the driving motor 25 can drive the glue container 22 to rotate through the transmission member. The transmission member is arranged in the accommodating cavity 214, so that the condition that the transmission member is exposed outside the connecting member 21 is avoided, the possibility that the transmission member is damaged by collision of an external object or other parts of the optical module packaging device can be reduced, the possibility that the transmission member enters sundries to influence the transmission effect can be reduced, and the transmission member can have a better transmission effect.

Of course, in other embodiments, the diameter of the transmission gear 26 sleeved on the rotating shaft 222 of the glue container 22 may be smaller than or equal to the diameter of the transmission gear 26 sleeved on the rotating shaft of the driving motor 25.
Referring to fig. 2, 5 and 6, in an embodiment, the dispensing assembly 20 further includes an adjusting assembly 23 and a glue scraping member 24 disposed on the adjusting assembly 23, the adjusting assembly 23 is disposed on the connecting member 21, the glue scraping member 24 is disposed above the glue accommodating member 22 and extends toward the glue accommodating member 22, and the adjusting assembly 23 is used for driving the glue scraping member 24 to move in an up-and-down direction. Specifically, when the glue scraping member 24 is mounted on the connecting member 21, at least a portion of the glue scraping member 24 is located above the glue accommodating member 22, and at least a portion of the glue scraping member 24 extends into the glue accommodating groove 221 and extends into the glue accommodating groove 221, and is spaced apart from the bottom of the glue accommodating groove 221. Through setting up the piece 24 of scraping gluey, and according to the thickness of holding gluey glue in the gluey groove 221, set up in advance and scrape gluey 24 height of holding gluey groove 221 relatively, when making scrape gluey 24 and hold gluey 22 relative rotations, can will hold gluey groove 221 in the protruding bonding glue of face up because of the adsorption of last lens through scraping gluey 24 promptly, thereby can guarantee to hold gluey surface layer of the bonding glue in the groove 221 comparatively level and smooth all the time, so make each lens can scribble the bonding glue of establishing comparatively evenly in holding gluey groove 221, can effectively reduce on the lens bonding glue and scribble and establish too much the condition. And through setting up adjusting part 23, can drive and scrape gluey piece 24 and move along the up-and-down direction to adjust and scrape the height that gluey piece 24 compares in holding gluey groove 221 tank bottom, in order to guarantee to hold the bonding glue in gluey groove 221 and reduce the back, also can strickle off the protruding part in bonding glue top layer through scraping gluey piece 24. Thereby, the bonding glue in the glue containing groove 221 can be fully used, and the frequency of supplementing the bonding glue into the glue containing groove 221 is reduced. Of course, in other embodiments, the glue scraping element 24 may be fixedly connected to the connecting element 21 in the up-down direction. Or only the squeegee member 24 may be provided. Or the squeegee member 24 may not be provided.
In one embodiment, adjustment assembly 23 includes an adjustment member 231, a resilient member 233, and a mounting member 234, wherein resilient member 233 and adjustment member 231 are disposed on connecting member 21, mounting member 234 is disposed on resilient member 233 and spaced apart from connecting member 21, squeegee member 24 is disposed on mounting member 234, and adjustment member 231 has a threaded rod 232 extending toward mounting member 234, and threaded rod 232 is configured to drive mounting member 234 toward connecting member 21. Specifically, the elastic member 233 has one end connected to the connection member 21 and the other end connected to the mounting member 234 such that the mounting member 234 is spaced apart from the connection member 21 and the extension direction of the screw 232 coincides with the moving direction. When the adjusting member 231 drives the screw 232 to move toward the mounting member 234, the screw 232 can abut against the mounting member 234, and the mounting member 234 can drive the scraping element 24 to move downward (i.e., to move toward the bottom of the glue receiving groove 221). During the downward movement of the mounting member 234, the elastic member 233 can be driven to be elastically deformed, and at this time, the elastic member 233 has a tendency to drive the mounting member 234 to move upward. Namely, after the screw 232 presses the mounting member 234 down to a proper position for fixing, the mounting member 234 and the frictioning member 24 can be in a balanced state under the action of the screw 232 and the elastic member 233, so that the purpose of adjusting the height of the frictioning member 24 relative to the bottom of the glue accommodating groove 221 can be achieved. When the adjusting screw 232 moves in the opposite direction and is away from the mounting member 234, the mounting member 234 can drive the scraping element 24 to automatically move upward and return under the action of the elastic member 233, so that the adjusting process of the scraping element 24 is convenient. In addition, in order to enable fine adjustment of the squeegee 24 in the up-down direction, the adjustment member 231 may be a differential head. Of course, in other embodiments, the elastic member 233 may not be provided. Alternatively, the squeegee member 24 may be attached to the screw 232 such that the screw 232 extends in the up-down direction.
In one embodiment, the elastic member 233 is a spring, and the connecting member 21 has a pad 213, one end of the spring is disposed at the upper end of the pad 213, and the other end is connected to the mounting member 234. Specifically, the elastic sheet is disposed above the connecting member 21 in parallel and spaced from the connecting member 21, that is, the thickness direction of the elastic sheet is consistent with the up-down direction, so that when the mounting member 234 is mounted at the end of the elastic sheet far away from the cushion block 213, the mounting member 234 is spaced from the connecting member 21, so as to ensure that the mounting member 234 and the frictioning member 24 move downward sufficiently. By providing the elastic member 233 in the form of a spring plate, the overall height of the dispensing assembly 20 in the up-down direction can be reduced due to the thinner spring plate. Of course, in other embodiments, the elastic member 233 may be a spring or a rubber pad.
In one embodiment, the number of the elastic pieces is multiple, the elastic pieces are arranged at intervals along the vertical direction, and the elastic pieces are connected with the mounting member 234. The acting force of the elastic piece 233 applied to the mounting piece 234 upwards can be increased, the possibility that the glue scraping piece 24 and the mounting piece 234 move downwards under the self gravity can be reduced, the glue scraping piece 24 is more stable in a balanced state, and the effect of scraping the surface of the bonding glue is better. The number of the elastic sheets can be two, three or four, and the like. Of course, in other embodiments, the number of the elastic pieces may be one.
In one embodiment, the screw 232 extends in a horizontal direction, the mounting member 234 has a slope 235 facing the screw 232, the slope 235 gradually inclines away from the connecting member 21 in the advancing direction of the screw 232, and the screw 232 can abut against the slope 235.
Specifically, the forward direction of the screw 232 refers to the direction in which the screw 232 moves toward the mounting member 234, and is also the extending direction of the screw 232, and the inclined surface 235 is inclined with respect to the vertical direction and is inclined with respect to the forward direction of the screw 232. When screw 232 moves towards inclined plane 235 to when the butt with inclined plane 235, inclined plane 235 receives the downward butt effort of screw 232, and when screw 232 continued to move towards advancing direction, when this butt effort is greater than the elasticity of elastic component 233, can push down mounting part 234 for mounting part 234 drives and scrapes gluey 24 and move down. Compared with the way that the screw 232 extends along the vertical direction, the overall height of the dispensing assembly 20 along the vertical direction can be reduced. Of course, in other embodiments, the screw 232 may also extend in the up-down direction.
In some configurations, for example, when the elastic member 233 is a spring, in order to prevent the mounting member 234 from moving along the forward direction of the screw 232, a limiting structure may be disposed on a side of the mounting member 234 facing away from the screw 232 to limit the movement of the mounting member 234 along the forward direction of the screw 232 and ensure that the mounting member 234 only moves downward. Of course, the position-limiting structure may not be provided, for example, in the embodiment where the elastic member 233 is an elastic piece, the elastic piece is disposed above the connecting member 21 in parallel, that is, the advancing direction of the screw 232 is perpendicular to the thickness direction of the elastic piece, and since the elastic piece mainly deforms in the thickness direction and is difficult to deform in the length direction and the width direction, when the screw 232 abuts against the inclined surface 235, the elastic piece mainly moves downward, and the deformation in the advancing direction of the screw 232 is extremely small, so that the position-limiting structure may not be provided.
In one embodiment, the glue container 221 is annular and disposed around the rotation axis 222 of the glue container 22. I.e. the axis of the glue-receiving slot 221 is substantially collinear with the axis of rotation 222 of the glue-receiving member 22. When the glue containing piece 22 is rotatably connected with the connecting piece 21, the lens can be ensured to be better coated with the bonding glue in the glue containing groove 221, so that when the area of the glue containing groove 221 is smaller, the requirement of coating the bonding glue on the lens can be met. So will hold gluey groove 221 setting and be cyclic annular, can enough guarantee to hold gluey piece 22 when rotating, frictioning piece 24 can strickle the bonding glue in holding gluey groove 221, also can avoid holding the extravagant condition of glue of gluey groove 221 central point position. Of course, in other embodiments, the glue containing groove 221 may be a circular groove.
Referring to fig. 7 and 8, in an embodiment, the connecting member 21 is rotatably connected to the base 10 and has a first state (refer to fig. 2) and a second state (refer to fig. 8), in the first state, the glue containing groove 221 is located below the material taking member 30 to allow the material taking member 30 to clamp the lens and coat the adhesive glue in the glue containing member 22, and in the second state, the glue containing groove 221 and the material taking member 30 are spaced apart from each other in the horizontal direction. The rotation axis 222 of the connecting member 21 extends along the opening direction of the glue containing groove 221, and the glue containing groove 221 and the rotation axis 222 of the connecting member 21 are arranged at intervals.
Specifically, the connecting member 21 is long, one end of the connecting member 21 is rotatably connected to the base 10 and is disposed beside the material taking member 30, and the other end is provided with a glue containing groove 221. Therefore, after the material taking part 30 clamps the lens on the circuit board on the placing seat 40 to perform optical path coupling and the accurate installation position of the lens on the circuit board is determined, the lens only needs to move upwards, then the glue containing part 22 moves to a position between the material taking part 30 and the circuit board, and the glue containing groove 221 is located below the material taking part 30 and the lens, so that the lens can move downwards and the glue containing groove 221 is coated with bonding glue. When the lens is stained with the bonding glue, the lens is moved upwards, and the glue containing member 22 is moved towards the direction away from the material taking member 30, so that the lens can be clamped by the material taking member 30 and moved downwards to be bonded on the circuit board. Owing to at this in-process, lens only need move along upper and lower direction, need not move along the horizontal direction, so reduced the moving range of lens at the point in-process of gluing to can reduce the error that produces when lens remove, when guaranteeing that lens bond on the circuit board, the bonding position of lens is less with the mounting position error that the coupling was confirmed, is favorable to improving the installation accuracy of lens, promptly the utility model discloses technical scheme can reduce the influence of the encapsulation accuracy of process to lens of gluing. In addition, compared with the sliding connection between the connecting member 21 and the base 10, a longer slide rail or other structure needs to be disposed on the base 10, so that the structure is simpler, and the occupied space on the base 10 is smaller. Of course, in other embodiments, the connecting member 21 may be slidably connected to the base 10.
In one embodiment, the base 10 is provided with a driving member 11, and the driving member 11 is drivingly connected to the connecting member 21. Particularly, the driving member 11 is a rotary cylinder, so that the connecting member 21 can be accurately positioned when rotating to the second state, and the rotary cylinder has a compact structure and a small installation space, and is beneficial to reducing the size of the optical module packaging device. Of course, in other embodiments, the driving member 11 may be a motor.
The above only is the preferred embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structure changes made by the contents of the specification and the drawings under the inventive concept of the present invention, or the direct/indirect application in other related technical fields are included in the patent protection scope of the present invention.
