Implementation

[0023] The following is combined with Figure 1 , Figure 2 The utility model is further described in detail with specific implementation methods.

[0024] Example 1: Please refer to Figure 1 to Figure 2 , a gluing mechanism, comprising:

[0025] A fixture 2 for holding an electronic component 23;

[0026] An XZ type moving mechanism is connected to the fixture 2 and drives the fixture 2 to move up and down and horizontally;

[0027] The rotating table 14 is connected to a rotating driving mechanism for driving the rotating table 14 to rotate;

[0028] The glue injection mechanism is used to provide liquid glue to the surface of the rotating table 14 .

[0029] When the technical solution is working, the X-type moving mechanism drives the clamp 2 to the loading area, and the clamp 2 clamps the electronic component 23. The surface of the electronic component 23 that needs to be coated is located on the lower bottom surface and lower than the clamp 2. Then the XZ-type moving mechanism drives the clamp 2 to move, so that the electronic component 23 moves to the top of the rotating table 14 and is close to the rotating table 14; the glue injection mechanism continuously injects glue into the surface of the rotating table 14, and the rotating drive mechanism drives the rotating table 14 to rotate. When the glue contacts the bottom surface of the electronic component 23, the glue sticks to the bottom surface, thereby completing the gluing process. After gluing is completed, the XZ-type moving mechanism drives the clamp 2 to move upward, and then moves horizontally to the unloading area, and releases the clamp 2. This reciprocating action is repeated. The entire process does not require manual operation.

[0030] See also Figure 2 Furthermore, the clamp 2 includes a finger cylinder, which includes two clamping blocks 20, the clamping block 20 is connected with an L-shaped clamping arm 21, the horizontal section of the L-shaped clamping arm 21 is provided with a connecting groove 22 that matches the clamping block 20, and the connecting groove 22 is provided with a plurality of connecting holes 24.

[0031] When clamping the electronic components 23, the present technical solution adopts the method of cooperating between the finger cylinder and the L-shaped clamp arm 21. The L-shaped clamp arm 21 can adjust the connection position with the clamp block 20 by setting the connection groove 22 to adapt to the electronic components 23 of different shapes and sizes.

[0032] Furthermore, the XZ type moving mechanism is connected to a rotary cylinder 3 , and the rotary cylinder is connected to the clamp 2 .

[0033] When working, the clamp 2 first clamps the electronic component 23 to be glued, and places it on the rotating table 14 for gluing. After gluing is completed, the product needs to be placed in the unloading area. When placing it in the unloading area, the product needs to face the glued surface upward, so a rotating cylinder 3 is set to flip the clamp 2 180 degrees to adjust the product position.

[0034] Furthermore, the glue injection mechanism includes a bracket arranged on one side of the rotating table 14 , the bracket is connected to a container 9 for storing glue, the lower end of the container 9 is connected to a guide tube 13 , and the guide tube 13 is located above the rotating table 14 .

[0035] The glue has a certain viscosity. The container 9 and the guide tube 13 are set above the rotating table 14. The glue will slowly flow out of the guide tube 13 and fall onto the rotating table 14. The aperture of the guide tube 13 is set to be smaller, and the glue flow rate is smaller. Combined with the rotation speed of the rotating table 14 and the feeding and gluing speed of the clamp 2, the glue can basically be kept on the rotating table 14.

[0036] Preferably, a heating device 11 is connected to the lower end of the container 9 .

[0037] The heating device 11 may be a thermocouple or the like, and is used to keep the glue in the container 9 in a liquid state.

[0038] More preferably, a glue injection hole is provided at the upper end of the container 9.

[0039] .Furthermore, an L-shaped connecting block 8 is connected to the side of the container 9, the vertical section of the L-shaped connecting block 8 is fixedly connected to the container 9, the horizontal section of the L-shaped connecting block 8 is provided with a through hole, and the bracket includes a vertical support rod 12, the upper end of the vertical support rod 12 is provided with an external thread and is connected to two limit nuts 10, the support rod passes through the through hole, and the two limit nuts 10 are respectively located on the upper and lower sides of the horizontal section.

[0040] The L-shaped connecting block 8 is connected to the support rod, and the height of the container 9 can be adjusted by adjusting the two limit nuts 10. When adjusting, the two limit nuts 10 can be moved to the upper and lower sides first, and then the height of the horizontal section can be adjusted. After the adjustment is completed, the two limit nuts 10 can be rotated to abut the horizontal section.

[0041] Furthermore, the driving mechanism includes driving cylinders 19 and 17 , and the rotating table 14 is rotatably connected to the driving cylinders 19 and 17 through a transmission mechanism. A support block 15 is provided on one side of 17 , and the support block 15 is connected to a scraper plate 16 , which is located above the rotating table 14 .

[0042] The transmission mechanism can be a reducer, etc., and the prior art will not be described in detail. By arranging the support block 15 and the scraper 16 on one side of 17, the glue can be prevented from gathering on the rotating table 14. During the rotation process, the scraper 16 scrapes the glue flat on the rotating table 14, so that the electronic components 23 can be glued more evenly.

[0043] Furthermore, the XZ type moving mechanism includes a support frame 7, the support frame 7 is connected to a horizontally laterally arranged linear motor 6, the linear motor 6 is connected to a vertical plate 5 and drives the vertical plate 5 to move horizontally, the vertical plate 5 is connected to a lifting cylinder 4, and the lifting cylinder 4 is connected to the rotating cylinder.

[0044] The XY type moving mechanism mainly includes a horizontal linear module and a vertical linear module connected to each other, which can be the existing technology. The technical solution adopts a combination of a horizontally arranged linear motor 6 and a lifting cylinder 4, and has a simple structure.

[0045] Furthermore, a loading conveying mechanism 1 and a unloading conveying mechanism 18 are provided on both sides of the rotating table 14 .

[0046] The loading conveying mechanism 1 and the unloading conveying mechanism 18 have the same structure, except that the conveying directions are opposite.

[0047] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention.
