DETAILED DESCRIPTION

[0028] The following is combined with Figure 1 To Attachment Figure 6 This application is described in further detail.

[0029] Due to structural limitations, the prior art glue filling head can generally only be provided with a single one, which can only process one electronic component at a time, resulting in low efficiency and large stroke waste.

[0030] Therefore, in order to increase the processing efficiency of the AB glue pouring device, that is, to be able to pour glue on multiple workpieces to be processed at the same time. This embodiment discloses an AB glue pouring device, which includes five systems, namely: a storage system 11, a feeding system 12, a three-axis displacement system 13, a pouring system 15, and a vacuum system 14. Specifically, the storage system 11 includes a protective shell and a tank A and a tank B placed in the protective shell. Tanks A and B are used to store glue A and glue B, respectively, and are transported to the stirring vacuum defoaming machine through their respective lifting pumps for defoaming treatment. The storage system 11 belongs to the prior art and will not be repeated here. The feeding system 12 includes at least two electronic infusion pumps for lifting and metering the amount of glue delivered. The feeding system 12 is connected to the storage system 11 through pipelines to lift glue A and glue B into the subsequent process, that is, the pouring system 15. The pouring system 15 passes through two input pipes, and the outer sides of the two input pipes are generally wrapped with protective pipes to enhance the structural strength. The input pipes are connected to the feeding system 12 to supply glue A and glue B respectively. The three-axis displacement system 13 is used to drive the glue pouring system 15 to move, and includes an X-axis displacement module, a Y-axis displacement module, and a Z-axis displacement module to control the movement of the glue pouring system 15 in three axes. The three-axis displacement system 13 belongs to the prior art and will not be described in detail here. The vacuum system 14 is used to place the glue pouring system 15 in a vacuum environment to avoid the generation of bubbles during glue pouring.

[0031] In order to enable the AB glue dispensing device to achieve multi-head dispensing, the dispensing system 15 is optimized in this embodiment. The details are as follows.

[0032] In this embodiment, the glue filling system 15 includes a double glue filling valve 2, a glue mixing and conveying component 3, a glue filling component 4 and a power component 5. The double glue filling valve 2 includes a valve body 21, which belongs to the prior art and is not described in detail here. Two input channels 211 are opened in the valve body 21, which are used to convey glue A and glue B respectively. The input channels 211 are respectively connected to the corresponding input pipes for pouring glue A or glue B.

[0033] The mixing glue conveying assembly 3 includes a mixing glue delivery pipe 31 and a mixing screw 34. One end of the mixing glue delivery pipe 31 is closed, and the other end is connected to two input channels 211 at the same time. The mixing screw 34 is coaxially rotatably connected to the mixing glue delivery pipe 31, and the two are clearance-matched. The outer diameter of the mixing screw 34 is slightly smaller than or equal to the inner diameter of the mixing glue delivery pipe 31. An annular chamfer 311 is provided on the inner wall of one end of the mixing glue delivery pipe 31 close to the connecting column 212. The maximum diameter of the chamfer 311 is greater than the maximum distance between the two input channels 211, and the diameter at the minimum is equal to the inner diameter of the mixing glue delivery pipe 31. Glue A and glue B flow into the mixing glue delivery pipe 31 through the corresponding input channels 211, and are mixed and transmitted downward by the mixing screw 34. The setting of the chamfer 311 is conducive to the smooth entry of glue A and glue B into the mixing glue delivery pipe 31 to prevent being blocked by the mixing screw 34.

[0034] Furthermore, a connecting column 212 is provided at the bottom of the valve body 21. The mixed rubber delivery pipe 31 is connected to the connecting column 212. The input channel 211 passes through the connecting column 212 along the axis and is connected to the mixed rubber delivery pipe 31.

[0035] Furthermore, the mixed rubber delivery hose 31 is coaxially connected with a first connecting sleeve 32 and a first adapter ring 33. The first adapter ring 33 is slidably connected to the outside of the mixed rubber delivery hose 31. One end of the first connecting sleeve 32 is rotatably connected to the first adapter ring 33, and the inner wall of the other end is provided with an internal thread. The connecting column 212 is provided with an external thread. The first connecting sleeve 32 is threadedly connected to the connecting column 212. A first groove 312 is provided on the outer wall of the mixed rubber delivery hose 31 along its length. A first protrusion 331 that can slide in the first groove 312 is provided on the inner wall of the first adapter ring 33.

[0036] The power assembly 5 includes a driving motor 51, a power transfer shell 53 and a power reversing component 54. The driving motor 51 is arranged at the upper end of the valve body 21 to reduce the space at the bottom of the AB glue filling device. The output shaft 511 of the driving motor 51 is coaxially connected to the mixing screw rod 34. The power transfer shell 53 is connected to the bottom of the mixing rubber delivery pipe 31. A round rod 341 is provided at one end of the mixing screw rod 34 away from the driving motor 51. The round rod 341 penetrates the mixing rubber delivery pipe 31 to the power transfer shell 53 and is connected to the power reversing component 54. Further, the output shaft 511 of the driving motor 51 passes through the valve body 21 to the connecting column 212, and is provided with a first transfer sleeve 52. A polygonal first connecting groove 521 is provided in the first transfer sleeve 52. A polygonal first connecting column 342 that can be inserted into the first connecting groove 521 is provided at the end of the mixing screw rod 34. The first connecting column 342 protrudes out of the extension surface of the upper surface of the mixing rubber delivery pipe 31. When the output shaft 511 rotates, the mixing screw rod 34 can be driven to rotate through the polygonal constraint.

[0037] Since the mixing screw rod 34 is disposed in the mixing rubber pipe 31, when connecting, the mixing rubber pipe 31 is first coaxially moved to the bottom of the connecting column 212, and then moved upward to the first connecting column 342 to be inserted into the first adapter sleeve 52, and the shape is matched, at which time the upper surface of the mixing rubber pipe 31 abuts against the lower surface of the connecting column 212. Slide the first adapter sleeve 52 to the external thread of the connecting column 212, and rotate the first adapter sleeve 52 until it is tightened, thereby completing the connection between the mixing rubber pipe 31 and the valve body 21. Since the power connection shell is fixedly connected to the mixing rubber pipe 31, the power connection shell is fixed together.

[0038] The glue filling assembly 4 includes two primary glue filling tubes 41, two sealing covers 42 and a plurality of secondary glue filling tubes 43. One end of the two primary glue filling tubes 41 is connected to the power transfer shell 53, and the other end extends in a direction away from each other. The power transfer shell 53 is fixedly connected to the primary glue filling tube 41 to provide support. The two primary glue filling tubes 41 are on the same straight line, and the primary glue filling tube 41 is perpendicular to the mixed glue delivery hose 31. The end of the primary glue filling tube 41 away from the power transfer shell 53 is penetrated outward, and the sealing cover 42 can cover one end of the primary glue filling tube 41 to close the primary glue filling tube 41. The secondary glue filling tube 43 is coaxially detachably connected to the end of the primary glue filling tube 41, that is, the end away from the power transfer shell 53. Both ends of the secondary glue filling tube 43 are penetrated. A plurality of secondary glue filling tubes 43 can be respectively connected to the two ends of the two primary glue filling tubes 41 to form a continuous glue filling pipeline. The sealing cover 42 can also seal the end of the secondary glue filling tube 43. When the secondary glue filling tube 43 is connected to the primary glue filling tube 41, the sealing cover 42 can close the secondary glue filling tube 43, so that a closed glue filling pipeline is formed inside the primary glue filling tube 41 and the secondary glue filling tube 43. The primary glue filling tube 41 is provided with a primary glue filling head 411, and the secondary glue filling tube 43 is provided with a secondary glue filling head 431. In this way, an AB mixed glue flow pipeline that can be expanded arbitrarily to adapt to different numbers of processed parts is formed. It is only necessary to remove the sealing cover 42, and then connect another secondary glue filling tube 43 to the tail of the primary glue filling tube 41 or the secondary glue filling tube 43, and connect the sealing cover 42.

[0039] In order to prevent the AB mixed glue from solidifying in the primary glue filling tube 41 or the secondary glue filling tube 43, and to further stir the AB mixed glue. At the same time, in order to transport the AB mixed glue more efficiently, prevent the AB glue from completely flowing out of the front primary glue filling tube 41 or the secondary glue filling tube 43, resulting in subsequent flow interruption. A primary screw rod 46 is coaxially rotatably connected in the primary glue filling tube 41, and the primary screw rod 46 is arranged perpendicular to the length direction of the mixing screw rod 34. A first light rod 461 is coaxially arranged at one end of the primary screw rod 46, and the first light rod 461 penetrates into the power adapter shell 53 and is connected to the power reversing component 54. A secondary screw rod 47 is rotatably connected in the secondary glue filling tube 43, and the secondary screw rod 47 is coaxially and detachably connected to the end of the primary screw rod 46.

[0040] Further, the secondary glue filling tube 43 is coaxially connected with a second connecting sleeve 44 and a second adapter ring 45. The second adapter ring 45 is slidably connected to the outside of the secondary glue filling tube 43. One end of the second connecting sleeve 44 is rotatably connected to the second adapter ring 45, and the inner wall of the other end is provided with an internal thread. The inner wall of the sealing cover 42 is provided with the same internal thread. The outer wall of the end of the primary glue filling tube 41 is provided with an external thread. The other end of the secondary glue filling tube 43 is provided with the same external thread. The second connecting sleeve 44 can be threadedly connected with the primary glue filling tube 41 or other secondary glue filling tubes 43. A second groove 432 is provided along the length of the outer wall of the secondary glue filling tube 43. The inner wall of the second adapter ring 45 is provided with a second protrusion 451 that can slide in the second groove 432. Further, one end of the secondary spiral rod 47 is provided with a second adapter sleeve 471, and the other end is provided with a third connecting column 472. A polygonal second connecting groove 4711 is provided in the second adapter sleeve 471. The end of the primary screw rod 46 is provided with a polygonal second connecting column 462 that can be inserted into the second connecting groove 4711. The structure of the third connecting column 472 is the same as that of the second connecting column 462. The second connecting column 462 protrudes outside the primary glue filling tube 41, and the third connecting column 472 protrudes outside the secondary glue filling tube 43. The second connecting sleeve 44, the second adapter ring 45, the first connecting sleeve 32, and the first adapter ring 33 have the same structure and principle, which will not be repeated here. Through this arrangement, the secondary glue filling tube 43 and the primary glue filling tube 41 or other secondary glue filling tubes 43 can be conveniently connected, and the sealing performance is high. The second connecting column 462, the second adapter sleeve 471, and the third adapter sleeve have the same structure and principle as the first connecting column 342 and the first adapter sleeve 52, which will not be repeated here. In this way, the secondary screw rod 47 can cooperate with the second adapter sleeve 471 or the third adapter sleeve through the second connecting column 462, so that when the primary screw rod 46 rotates, several secondary screw rods 47 are driven to rotate simultaneously. In addition, a circular counterbore 421 is formed on the sealing cover 42 , and the third adapter sleeve or the second adapter sleeve 471 at the end is accommodated through the circular counterbore 421 .

[0041] The glue pouring assembly 4 also includes a transition box 48. The transition box 48 is connected to the power transfer shell 53. A first through groove 313 communicating with the internal space is provided at the bottom of the mixed glue delivery pipe 31, and a second through groove 412 is provided at the upper end of the first-level glue pouring pipe 41 close to the power transfer shell 53. The space inside the transition box 48 is arranged in an inverted T shape, with the upper end connected to the mixed glue delivery pipe 31 through the first through groove 313, and the lower two ends are respectively connected to the corresponding first-level glue pouring pipe 41 through the corresponding second through grooves 412. The bottom inner wall of the internal space of the transition box 48 is higher than the plane where the horizontal diameter of the first-level glue pouring pipe 41 is located to prevent backflow. The bottom of the internal space of the transition box 48 is inclined to improve the flow efficiency of the AB mixed glue. The outer surface of the transition box 48 is covered with an insulation layer 481, and the insulation layer 481 is made of materials such as asbestos, which plays a role in weakening the heat exchange capacity between the transition box 48 and the external space.

[0042] Further, the power reversing component 54 includes a reversing worm 541 and two worm wheels 542. The reversing worm 541 is rotatably connected to the power transfer shell 53. The round rod 341 is coaxially connected to the reversing worm 541. The worm wheel 542 is rotatably connected to the power transfer shell 53. The worm wheels 542 are separated on both sides of the reversing worm 541 and mesh with the reversing worm 541 at the same time. Further, the power reversing component 54 also includes two active bevel gears 543 and two driven bevel gears 544. The first light rod 461 penetrates into the power transfer shell 53 and coaxially connects the bevel gears. The driven bevel gear 544 meshes with the active bevel gear 543. The active bevel gear 543 is connected to the center of the corresponding worm wheel 542 through a rotating shaft. The power supplied by the output shaft 511 of the drive motor 51 is transmitted through the cooperation of the worm wheel 542 and the reversing worm 541, avoiding the need for another power source to save costs. At the same time, it can also reduce the bottom space of the AB glue filling device, making the device more integrated.

[0043] The implementation principle of an AB glue pouring device in the embodiment of the present application is as follows: The double glue filling valve 2 is supplied with glue A and glue B through the material storage system 11 and the material supply system 12. Glue A and glue B are mixed in the mixed glue delivery pipe 31, and the mixing screw rod 34 is driven to rotate by the output shaft 511 of the driving motor 51, so that glue A and glue B are mixed and transported. The AB mixed glue enters the transition box 48 through the first through groove 313, and enters the first-level glue filling pipe 41 through the second through groove 412. Under the rotation of the first-level screw rod 46, it is delivered to the workpiece to be processed by the first-level glue filling head 411. The remaining AB mixed glue enters the second-level glue filling pipe 43 in turn, is transported by the second-level screw rod 47, and is poured onto the workpiece to be processed at the second-level glue filling head 431. The power of the first-level screw rod 46 and the second-level screw rod 47 are both converted by the power reversing component 54 to convert the power of the mixing screw rod 34.

[0044] The double glue filling valve is displaced by a three-axis displacement system to adapt to the position of the workpiece to be processed.

[0045] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
