Description

Technical Field

[0001] The present invention relates to the technical field of electronic component assembly, and in particular to an assembly pressure-maintaining mechanism. Background Art

[0002] When assembling the light guide column, the assembly and pressure holding process of the light guide column is involved. During the installation process, the light guide column needs to be glued first. After completing the gluing process, the light guide column with glue is assembled into the mounting hole of the shell. In order to ensure that the light guide column and the mounting hole of the shell are firmly bonded, the pressure holding process is finally performed.

[0003] The light guide column has small dimensions and high assembly precision requirements, and fine adjustment is required during assembly to ensure assembly precision.

[0051] When assembling the light guide column, the assembly and pressure holding processes of the light guide column are involved. During the installation process, the light guide column needs to be glued first. After the gluing process is completed, the light guide column with glue is assembled into the mounting hole of the shell. In order to ensure that the light guide column and the mounting hole of the shell are firmly bonded, the pressure holding process is finally performed. The light guide column has small dimensions and high assembly precision requirements. Fine adjustment is required during assembly to ensure assembly precision. Therefore, when using an adjustment assembly pressure holding mechanism with a large unit stroke to adjust the light guide column close to the shell, deviations in the assembly may cause scratches or breakage of the light guide column, or affect the assembly precision of the light guide column. When using an adjustment mechanism with a small unit stroke to adjust the light guide column to pass through the mounting hole, the assembly efficiency of the light guide column will be affected.

[0052] In order to solve the above problems, the present invention provides an assembly pressure maintaining mechanism 100. Figures 1 to 6 This is a specific embodiment of the assembly pressure maintaining mechanism 100 provided by the present invention.

[0053] See also Figures 1 to 3 The assembly pressure maintaining mechanism 100 includes a mounting seat 1, two fixing parts and an adjustment mechanism, the two fixing parts are arranged on the mounting seat 1, the two fixing parts are corresponding to the installation of the shell and the light guide column, and at least one of the fixing parts can be movably arranged in the first direction, the second direction and the third direction, so that the mounting holes on the shell on the two fixing parts and the light guide column can approach and move away from each other in the first direction, and adjust the facing positions in the second direction and the third direction; the adjustment mechanism is used to drive the movably set fixing part to move along the first direction, and the adjustment mechanism includes a coarse adjustment mechanism 8 and a fine adjustment mechanism 9, the coarse adjustment mechanism 8 is used to adjust the position of the movably set fixing part on the first half of the assembly stroke, and the fine adjustment mechanism 9 is used to adjust the position of the movably set fixing part on the second half of the assembly stroke.

[0054] In the technical solution provided by the present invention, two fixing parts are provided on the mounting seat 1, one of which is used to fix the shell, and the other fixing part is used to fix the light guide column. At least one of the two fixing parts can be movably set in the first direction, the second direction and the third direction. By adjusting the movably set fixing part to move along the second direction and the third direction, the center of the light guide column and the center of the mounting hole can be aligned. When the fixing part that can be moved along the first direction is adjusted to move along the first direction, when the light guide column is far away from the mounting hole on the shell, the coarse adjustment mechanism 8 realizes rapid coarse adjustment of the light guide column, thereby improving assembly efficiency. When the light guide column is close to the mounting hole on the shell, the fine adjustment mechanism 9 realizes fine adjustment of the light guide column, thereby ensuring assembly accuracy, thereby providing an assembly pressure maintaining mechanism 100 that can ensure assembly accuracy while improving assembly efficiency.

[0055] Specifically, in this embodiment, the two fixing parts include a first fixing part 21 and a second fixing part 22, the first fixing part 21 is used to fix the light guide column, and the first fixing part 21 is movably provided on the mounting seat 1 along the first direction, and is used to adjust the light guide column to approach or move away from the shell in the first direction; the second fixing part 22 is used to fix the shell, and the second fixing part 22 is movably provided on the mounting seat 1 along the second direction and the third direction, and is used to adjust the alignment between the shell and the light guide column.

[0056] Specifically, the fine adjustment mechanism 9 is movably provided on the coarse adjustment mechanism 8 along the first direction, and the first fixed part 21 is movably provided on the fine adjustment mechanism 9 along the first direction. The coarse adjustment mechanism 8 is used to drive the fine adjustment mechanism 9 to drive the first fixed part 21 to move along the first direction to adjust the position of the first fixed part 21 on the front half of the assembly stroke. The fine adjustment mechanism 9 is used to drive the first fixed part 21 to move along the first direction to adjust the position of the first fixed part 21 on the back half of the assembly stroke.

[0057] Specifically, see Figure 5 In this embodiment, the coarse adjustment mechanism 8 includes a first fixed seat 81, a first slider 82, and a first adjustment member 83. The first fixed seat 81 is mounted on the mounting seat 1; a first guide rail is provided on the first fixed seat 81, and the first slider 82 has a sliding groove along the first direction that cooperates with the guide rail, so that the first slider 82 can be slidably mounted on the first fixed seat 81 in the first direction. The fine adjustment mechanism 9 is mounted on the first slider 82. When the first slider 82 slides in the first direction, it drives the fine adjustment mechanism 9 to move synchronously in the up and down directions. The first adjustment member 83 is mounted on the first fixed seat 81 and has a first adjustment portion that is movable along the first direction. The first adjustment portion is connected to the first slider 82. In this way, when the first adjustment member 83 performs coarse adjustment, the first adjustment portion can drive the first slider 82 to move in the first direction, ultimately adjusting the fine adjustment mechanism 9 to drive the first fixed portion 21 to move along the first direction.

[0058] It should be noted that the first adjustment member 83 can be electrically adjustable or manually adjustable. Preferably, the first adjustment member 83 is a quick clamp, and the push rod of the quick clamp forms the first adjustment portion. Since the quick clamp is a prior art, it will not be described in detail here.

[0059] Specifically, see Figure 6In this embodiment, the fine-adjusting mechanism 9 includes a second fixing seat 91, a second elastic member 92 and a second adjusting member 93. The second fixing seat 91 is provided on the first slider 82, and the first fixing portion 21 is slidably mounted on the second fixing seat 91 along the first direction; the second elastic member 92 is retractable in the first direction, and the first fixing portion 21 is movably mounted on the second fixing seat 91 through the second elastic member 92; the second adjusting member 93 is installed on the second fixing seat 91, and has a second adjusting portion movably provided along the first direction, and the second adjusting portion is used to resist the first fixing portion 21, so that the first fixing portion 21 can move synchronously with the second adjusting portion along the first direction close to the mounting hole. When the second adjusting portion moves along the first direction to separate from the first fixing portion 21, the second elastic member 92 is used to provide a tightening force for the light guide column on the first fixing portion 21 to resist the flush portion. It should be noted that the second elastic member 92 can be set as a compression spring. When the first fixing part 21 is in the initial state, the compression spring is in the maximum compression amount. When the second adjusting part is gradually adjusted, the compression spring drives the first fixing part 21 to gradually approach the mounting hole, and the deformation of the compression spring gradually decreases. When the light guide column is against the flush part, the second adjusting part continues to adjust and gradually separates from the first fixing part 21. The compression spring provides a gradually increasing pressing force for the assembly of the light guide column. After the second adjusting part is completely separated from the first fixing part 21, the compression spring provides a continuous and constant pressure holding for the light guide column.

[0060] Preferably, the second adjusting member 93 comprises a micrometer, and a screw of the micrometer forms the second adjusting portion.

[0061] Specifically, in this embodiment, the assembly pressure maintaining mechanism 100 also includes a first driving device 5 and a second driving device 6 provided on the mounting seat 1, the first driving device 5 having a first driving part 51 that moves along the second direction; the second driving device 6 is connected to the first driving part 51, and has a second driving part 61 that moves along the third direction, and the second driving part 61 is connected to the second fixed part 22, so that the second fixed part 22 drives the light guide column to move along the second direction and the third direction.

[0062] Specifically, in this embodiment, the assembly pressure maintaining mechanism 100 also includes a first fixed block 71, a movable block 72 and a second fixed block 73. The first fixed block 71 is fixed to the mounting seat 1, and the first fixed block 71 is fixed to the first driving device 5; the movable block 72 is movably mounted on the first fixed block 71 along the second direction and the third direction, the second driving device 6 is fixed to the movable block 72, the first driving part 51 is fixedly connected to the movable block 72, and the first driving part 51 drives the movable block 72 and the second driving device 6 to move along the second direction; the second fixed part 22 is installed on the second fixed block 73, the second fixed block 73 is fixedly connected to the second driving part 61, and the second driving part 61 drives the second fixed block 73 to move along the third direction.

[0063] Specifically, the movable block 72 includes a first movable part 721 and a second movable part 722 arranged in sequence in the first direction, the first movable part 721 extends along the second direction, and the second movable part 722 extends along the third direction. A first limiting groove is provided on the first fixed block 71, and the first limiting groove laterally penetrates the first fixed block 71 in the second direction. A second limiting groove is provided on the second fixed block 73, and the second limiting groove laterally penetrates the second fixed block 73 in the third direction. The second movable part 722 is provided in the second limiting groove. In this way, the movable block 72 is installed between the second fixed block 73 and the first fixed block, which, on the one hand, prevents external dust from entering between the movable block 72 and the second fixed block 73 and the first fixed block, thereby preventing the movement from being obstructed or affecting the adjustment accuracy.

[0064] Specifically, in this embodiment, the first drive device 5 includes a first ball screw, which includes a first drive nut, and the first drive portion 51 includes the first drive nut; and / or the second drive device 6 includes a second ball screw, which includes a second drive nut, and the second drive portion 61 includes the second drive nut. Manually adjusting the screw ensures the adjustment accuracy of the second fixing portion 22 and facilitates real-time control of the movable distance of the second fixing portion 22.

[0065] Specifically, see Figure 4In this embodiment, the assembly pressure-maintaining mechanism 100 further includes a flush portion for abutting against the outer end surface of the shell, and the second fixing portion 22 includes a mold base 221, a flip cover plate 222 and a second fixing buckle 223. The mold base 221 is arranged on the mounting seat 1, and is formed with a positioning groove 212a for accommodating the shell. The positioning groove 212a is provided with an opening at one end in the first direction, and the flush portion is provided corresponding to the opening. The inner wall of the positioning groove 212a is penetrated by a through opening 222a for the first fixing portion 21 to extend into the positioning groove 212a. In this way, when the shell is buckled into the positioning groove 212a, the positioning groove 212a controls the single-side gap to be 0.05 mm, so that the positioning accuracy of the shell is high. The flip cover 222 is movably mounted on the mold base 221. The flip cover 222 is used to open and close the notch of the positioning slot 212a, preventing the housing from sliding out of the notch of the positioning slot 212a and preventing the housing from moving in the second or third directions during assembly. When the flip cover 222 is rotated, the second fixing buckle 223 is correspondingly arranged with the movable end of the flip cover 222. When the flip cover 222 closes the notch of the positioning slot 212a, the second fixing buckle 223 fixes the flip cover 222 to the mold base 221, preventing the flip cover 222 from rotating freely. The through opening 222a is provided to facilitate the first fixing portion 21 to extend into the housing for installation of the light guide.

[0066] Furthermore, since it is necessary to dispense glue on the light guide column before assembling and pressurizing the light guide column, in order to facilitate the dispensing, in this embodiment, the first fixing part 21 includes a fixing body 211 and a fixing tool 212, and the fixing body 211 is movably arranged on the mounting seat 1 along the first direction, and the fixing tool 212 is detachably installed on the fixing body 211. The fixing tool 212 is used to fix the light guide column, so that the light guide column can be moved from the dispensing station to the pressure holding station, and it is also convenient to install and fix the light guide column on the fixing body 211 through the fixing tool 212.

[0067] Furthermore, in one embodiment, a positioning protrusion is provided on the fixed body 211, and a positioning groove 212a is formed on the fixing fixture 212 to cooperate with the positioning protrusion. In this way, the fixing fixture 212 can be accurately positioned by plugging and fitting the positioning groove 212a with the positioning protrusion. In another embodiment, a first magnetic part is provided on the fixed body 211, and a second magnetic part 2121 is provided on the fixing fixture 212 to be magnetically connected to the first magnetic part. Such an arrangement prevents the fixing fixture 212 from falling off the fixed body 211. The form of the fixed body 211 and the fixing fixture 212 can be selected from the above-mentioned embodiments, or all the technical features of the above-mentioned two embodiments can be selected.

[0068] Furthermore, to facilitate observation of the relative position between the light guide and the mounting hole, in this embodiment, the fixture 212 is further provided with a power supply unit 213 for supplying power to the light guide. After the fixture 212 is mounted on the fixed body 211, the power supply unit 213 supplies power to the light guide, causing the light guide to emit light for easier monitoring.

[0069] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention.
