[0036] Reference Figure 1-8 As shown, the present invention provides a technical solution for a mobile phone frame glue dispensing device:

[0037] A mobile phone frame glue dispensing device includes a fixed clamping assembly 1, a main top rail assembly 2, a first dynamic clamping assembly 3, a second dynamic clamping assembly 4, a first rail fixing assembly 5, a second rail fixing assembly 6, and a glue dispensing assembly 7. It should be noted that the fixed clamping assembly 1, the first dynamic clamping assembly 3, and the second dynamic clamping assembly 4 work together to clamp and position the mobile phone frame 9, and the main top rail assembly 2, the first rail fixing assembly 5, and the second rail fixing assembly 6 work together and synchronously complete the rail fixing operation through the setting of the telescopic rod 81, thereby allowing the glue dispensing assembly 7 to perform the glue dispensing operation conveniently and efficiently.

[0038] Reference Figure 2-7As shown, three fixed clamping assemblies 1 are provided, which are T-shaped after being combined. The fixed clamping assembly 1 includes a hollow cavity rod 11, and the outer end of the hollow cavity rod 11 is provided with an end block 13. The side wall of the hollow cavity rod 11 is symmetrically provided with a number of side through-holes 12. The interior of the hollow cavity rod 11 is slidably connected with an inner slide rod 15 along its length direction. The side wall of the inner slide rod 15 is symmetrically provided with a number of elastic bent pieces 16. The interior of the inner slide rod 15 is rotatably connected with an inner rotating shaft 17. The end of the inner rotating shaft 17 is fixedly connected with an end threaded shaft 18. A threaded through-hole 14 is provided on the end block 13, and the end threaded shaft 18 is threadedly connected to the end block 13 at the threaded through-hole 14. It should be noted that the outer surface of the end threaded shaft 18 extending out of the end block 13 is roughened, including but not limited to structural settings such as protrusions and grooves, so that the user can easily rotate the end threaded shaft 18. When the user rotates the end threaded shaft 18, the inner slide rod 15 is controlled to slide toward the end block 13 inside the hollow cavity rod 11, so that the elastic bent piece 16 is retracted into the side hole 12 under the extrusion of the side hole 12, so that the first slide sleeve 31 and the second slide sleeve 41 in the first dynamic clamping component 3 or the second dynamic clamping component 4 can slide toward the end block 13, thereby greatly expanding the area formed by the first slide sleeve 31, the second slide sleeve 41, the second clamping rod 42 and the first clamping rod 32 to adapt to the changes in the size of the mobile phone frame part 9, greatly improving the flexibility of the device, and convenient operation to efficiently achieve clamping of mobile phone frame parts 9 of different sizes.

[0039] Reference Figure 2 As shown, the top surface of the fixed clamping assembly 1 is located at the intersection of the three fixed clamping assemblies 1 and is provided with a vertical slide rod 8. The main top rail assembly 2 includes a vertical slide frame 21 that is slidably connected to the vertical slide rod 8 and can be locked. The side walls of the vertical slide frame 21 are located above the hollow cavity rod 11 and are provided with side rods 23. The top surface of the side rod 23 is provided with a first rail groove 24.

[0040] Reference Figure 2-5 As shown, the first dynamic clamping assembly 3 includes a first sliding sleeve 31, a first clamping rod 32, and a protrusion 33. The protrusion 33 is arranged on the inner wall of the first sliding sleeve 31, and the first clamping rod 32 is arranged on the outer wall of the first sliding sleeve 31. The second dynamic clamping assembly 4 includes a second sliding sleeve 41 and a second clamping rod 42. The second clamping rods 42 are arranged on the two symmetrical outer walls of the second sliding sleeve 41, with two second clamping rods 42 arranged on each side. The inner wall of the second sliding sleeve 41 is also provided with a protrusion 33. The first dynamic clamping assembly 3 and the second dynamic clamping assembly 4 are slidably arranged on the hollow cavity rod 11, and the first rail fixing assembly 5 and the second rail fixing assembly 6 are slidably arranged on the side rod 23.

[0041] Reference Figure 2As shown, the first track fixing assembly 5 includes a third sliding sleeve 51, a first limiting rod 52, and a second track groove 53. The third sliding sleeve 51 is slidably connected to the side rod 23. The first limiting rod 52 is set on the outer side wall of the third sliding sleeve 51. The second track groove 53 is opened on the top surface of the first limiting rod 52. The second track fixing assembly 6 includes a fourth sliding sleeve 61, a second upper limiting rod 62 and a second lower limiting rod 63. The fourth sliding sleeve 61 is slidably connected to the side rod 23. The second upper limiting rod 62 is set on the two symmetrical outer side walls of the fourth sliding sleeve 61, with two provided on each side. The second lower limiting rod 63 is set on the two symmetrical outer side walls of the fourth sliding sleeve 61.

[0042] Reference Figure 1 and Figure 8 As shown, the glue dispensing assembly 7 includes a block 71, a cushion block 72, a horizontal slide bar 73, a grip bar 74, a collar 75, a glue injection tube 76 and a glue storage cavity 77. The cushion block 72 is arranged at the lower part of the block 71, the grip bar 74 is arranged at the top of the block 71, the horizontal slide bar 73 is locked and slidably connected to the block 71, the collar 75 is arranged at one end of the horizontal slide bar 73, the collar 75 is sleeved with the glue injection tube 76, and the glue storage cavity 77 is arranged at the top of the glue injection tube 76. It should be noted that, referring to Figure 8 As shown, the block 71 is connected to a screw through a thread to lock the horizontal slide bar 73. Through such a setting, the distance between the glue injection tube 76 and the edge of the mobile phone frame 9 can be adjusted to improve the flexibility of the device. When the amount of glue required is large due to the large size of the mobile phone frame (to ensure the stability of adhesion), the distance between the glue injection tube 76 and the edge of the mobile phone frame 9 is increased to prevent the glue from collapsing under the action of gravity and leaking from the edge of the mobile phone frame 9. It should also be noted that the top of the glue storage cavity 77 can be opened and closed, and specifically can be set to a cover with a thread connected to the thread thereof for adding glue to the inside thereof. The middle material can be made of extrudable materials such as rubber and plastic, so that it can be extruded and the glue stored inside is evenly squeezed out through the glue injection tube 76 (the glue injection tube 76 is connected to the glue storage cavity 77). Finally, the setting of the pad 72 is used to slide in contact with the side rod 23, the first limit rod 52 or the second limit rod 62, thereby improving the sliding stability of the dispensing component 7 and avoiding excessive wear of the horizontal slide rod 73, which affects its service life.

[0043] Reference Figure 1 and Figure 2 As shown, a telescopic rod 81 is provided between the third sliding sleeve 51 and the first sliding sleeve 31, and a telescopic rod 81 is also provided between the fourth sliding sleeve 61 and the second sliding sleeve 41. It should be noted that the telescopic rod 81 is telescopic, and its specific structure is prior art and will not be described in detail here.

[0044] Reference Figure 2As shown, in an optional embodiment: the vertical sliding frame 21 is locked on the vertical sliding rod 8 by a fastening screw 22, and the fastening screw 22 is threadedly connected to the side wall of the vertical sliding frame 21. The fastening screw 22 passes through the side wall of the vertical sliding frame 21 and presses against the vertical sliding rod 8 to lock the position of the vertical sliding frame 21 on the vertical sliding rod 8. It should be noted that through the arrangement of the vertical sliding frame 21 and the vertical sliding rod 8, the device can adjust the distance between the dispensing component 7 and the mobile phone frame 9 to adapt to mobile phone frame members 9 of different heights, thereby improving the flexibility of the device.

[0045] Reference Figure 2 and Figure 3 As shown, there are three side bars 23, and the vertical sliding frame 21 and the three side bars 23 are combined to form a T shape. The top surface of the side bar 23 where the fourth sliding sleeve 61 is located is provided with a first rail groove 24 on both sides. Figure 2 As shown, two first sliding sleeves 31 are provided, and one second sliding sleeve 41 is provided, and both the first sliding sleeve 31 and the second sliding sleeve 41 are slidably connected to the hollow cavity rod 11. One of the three hollow cavity rods 11 is arranged in the middle of the other two symmetrically arranged hollow cavity rods 11. It should be supplemented that the first sliding sleeve 31 is slidably connected to the symmetrically arranged hollow cavity rods 11, and the second sliding sleeve 41 is arranged on the asymmetrically arranged hollow cavity rod 11.

[0046] It should be noted that, referring to Figure 4 As shown, the elastic bent piece 16 can be controlled to extend out of the side opening 12, and the two symmetrically arranged first sliding sleeves 31 can be moved closer to each other. It should be noted that the elastic bent piece 16 is oriented toward the intersection of the three fixed clamping components 1.

[0047] Reference Figure 6 As shown, a plurality of elastic bent pieces 16 are arranged at equal intervals along the sliding direction of the first sliding sleeve 31 , and a plurality of protrusions 33 are arranged at equal intervals along the sliding direction of the first sliding sleeve 31 or the second sliding sleeve 41 .

[0048] It should be noted that the elastic bent piece 16 is elastic as the name implies. The elastic bent piece 16 and the protrusion 33 are arranged so that the first sliding sleeve 31 or the second sliding sleeve 41 can only slide in one direction. Figure 5 As shown, the user pushes the first slide 31 or the second slide 41 to slide on the hollow cavity rod 11 to adapt to the size of the mobile phone frame part 9. After the protrusion 33 bends the elastic bent piece 16, the elastic bent piece 16 returns to its original shape, thereby clamping the protrusion 33, thereby clamping the mobile phone frame part 9 between the first slide 31, the second slide 41, the first clamping rod 32 and the second clamping rod 42, thereby completing the fixation of the mobile phone frame part 9.

[0049] It should be noted that, referring to Figure 4As shown, the first clamping rod 32 slides in the gap between the two second clamping rods 42, referring to Figure 1 and Figure 2 As shown, the clamping block 71 slides in the gaps between the first rail groove 24 , the second rail groove 53 and the two second upper limit rods 62 .

[0050] It should be noted that the top and bottom surfaces of the first clamping rod 32 slide in contact with the second clamping rod 42, the clamping block 71 slides in contact with the inner side surfaces of the first rail groove 24 and the second rail groove 53, and slides in contact with the two second upper limit rods 62. This arrangement makes the dispensing component 7 more stable during the dispensing process, thereby improving the dispensing quality.

[0051] Reference Figure 5 As shown, the first sliding sleeve 31, the first clamping rod 32, the second clamping rod 42 and the second sliding sleeve 41 are used to clamp the mobile phone frame member 9, refer to Figure 8 As shown, a pull ring is provided on the outer side wall of the handle 74 . It should be noted that the provision of the pull ring facilitates the user to push the handle 74 .

[0052] The working principle of this device is further explained and supplemented through the working process of this device: when using this device to perform glue dispensing operation on the mobile phone frame part 9, it is only necessary to place the mobile phone frame part 9 between the first slide 31, the first clamping rod 32, the second slide 41 and the second clamping rod 42, and then push the first slide 31 and the second slide 41 to achieve clamping and positioning of the mobile phone frame part 9. In this process, due to the setting of the telescopic rod 81, the length of the gap between the first rail groove 24, the second rail groove 53 and the two second upper limit rods 62 corresponds to the four side dimensions of the mobile phone frame part 9. At this time, the user pushes the block 71 to slide in the gap between the first rail groove 24, the second rail groove 53 and the two second upper limit rods 62 through the grip rod 74, and squeezes the glue storage cavity 77 during the pushing process, so that the glue in the glue storage cavity 77 can be squeezed out from the glue injection tube 76 and fall on the edge of the mobile phone frame part 9, completing the glue dispensing operation.

[0053] Through the arrangement of the fixed clamping component 1, the main top rail component 2, the first dynamic clamping component 3, the second dynamic clamping component 4, the first rail fixing component 5, the second rail fixing component 6, the vertical slide bar 8 and the telescopic rod 81, the rail fixing operation is successfully completed in the process of clamping and positioning the mobile phone frame part 9, thereby facilitating the glue dispensing operation of the glue dispensing component 7, greatly improving the glue dispensing efficiency and accuracy, and the device can simultaneously complete the clamping, positioning, rail fixing and glue dispensing of two mobile phone frame parts 9, further improving the glue dispensing efficiency of the device, finally, the device can flexibly adjust the position of the first slide sleeve 31, the second slide sleeve 41 and the vertical slide frame 21, so as to adapt to the clamping, positioning and glue dispensing of mobile phone frame parts 9 of different sizes, with high flexibility and convenient operation, and is suitable for promotion and use in the glue dispensing process of mobile phone frames.

[0054] Because the elastic bent piece 16 is elastic, the first slide sleeve 31 or the second slide sleeve 41 can move a short distance toward the end block 13 without rotating the end threaded shaft 18. At this time, the elastic bent piece 16 is pushed toward the end block 13 by the protrusion 33 in the first slide sleeve 31 or the second slide sleeve 41. Through such a setting, when the mobile phone frame part 9 of the same size is replaced for glue dispensing operation, the device does not need to rotate the end threaded shaft 18. The elastic bent piece 16 is retracted into the side hole 12 to slide the first slide sleeve 31 toward the end block 13. Only the first slide sleeve 31 or the second slide sleeve 41 needs to be pushed lightly to take out the mobile phone frame part 9 after glue dispensing, and then the new mobile phone frame part 9 can be put in. The clamping and positioning can be completed by letting go. Through such a setting, the glue dispensing efficiency of the device for a large number of mobile phone frame parts 9 is greatly improved, which is more suitable for mass production.

[0055] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
