Example (b):
in the prior art, the device of the dispenser is mature, but the requirement of the dispenser on the higher accuracy of the 5G mobile phone is not satisfied, if the device structure is completely redesigned, the difficulty is very high, and the investment is very high.
Specifically, referring to fig. 1, an automatic spot heat-conducting gel device in the prior art generally includes a base, a plastic suction box positioning mechanism fixed on the base, a four-axis manipulator capable of being controlled by a control system, a feeding and discharging mechanism arranged on the four-axis manipulator, a glue dispensing mechanism, and a visual positioning mechanism; through the cooperation of these mechanisms, the automatic dispensing thermal conductive gel operation of the mobile phone (such as an optical module automatic dispensing thermal conductive gel device shown in application No. 2018201556742) is completed. The specific structure, operation principle and operation method of such devices are all the prior art, and are not described herein.
In contrast, the present embodiment is an improvement of the dispensing mechanism. Firstly, referring to fig. 2, the glue dispensing mechanism comprises a mounting plate 1, a cylinder 2, a glue spraying valve 3 and a hot reflux assembly, wherein the mounting plate is fixed on a four-shaft mechanical arm, the cylinder is fixed on the mounting plate, the glue spraying valve is arranged on the mounting plate in a vertically sliding manner, and the glue spraying valve is connected with the cylinder so as to move up and down under the driving of the cylinder.
In detail, referring to fig. 2 and 3, the thermal reflow assembly includes an annular heat shield 4, a cylindrical heat shield 41, a shield support 42, and a heat conductive coil 43. The side view of the annular heat insulation baffle 41 is in a circular truncated cone shape with a large top and a small bottom, a through hole in the middle part is enough for the needle tube of the glue spraying valve 3 to pass through, and the radial extension line of the annular heat insulation baffle 4 is positioned on the needle tube above the outlet of the needle tube to ensure that the outlet of the needle tube just extends out of the through hole in the middle part of the annular heat insulation baffle. The cylindrical heat insulation baffle 41 is cylindrical and is positioned above the annular heat insulation baffle, the lower edge of the cylindrical heat insulation baffle is connected with the outer edge of the annular heat insulation baffle, and an included angle of 90-120 degrees is formed between the annular heat insulation baffle and the cylindrical heat insulation baffle 41 in the cross section. The baffle bracket 42 comprises at least two 7-shaped, C-shaped, 1-shaped or U-shaped connecting frames, one end of each connecting frame is fixed on the outer surface of the glue spraying valve 3, and the other end of each connecting frame is fixed on the cylindrical heat insulation baffle 41 to support the whole hot reflux assembly. The heat conductive coil 43 is annularly disposed at a corner of the cylindrical heat insulating barrier between the annular heat insulating barriers. With the arrangement, a fan-shaped heat radiation surface is formed between the annular heat insulation baffle plate 4 and the cylindrical heat insulation baffle plate 41, and the glue spraying valve needle pipe is always maintained in a stable temperature range by the heat of the heat radiation surface. The mode of maintaining the temperature of the heat radiation is mild, the condition of sudden temperature change cannot occur, and due to the arrangement of the annular heat insulation baffle plate 4 and the cylindrical heat insulation baffle plate 41, the lowest position of the annular heat insulation baffle plate is higher than the outlet position of the needle tube of the glue spraying valve 3 and lower than the highest end of the needle tube, the heat cannot radiate to 5G mobile phone parts to be glued, the glue is ensured to be uniformly and not solidified, and the glue dispensing operation and the glue dispensing effect cannot be influenced. The structure is very simple, but the arrangement is very ingenious. The heat conducting coil wound by the common needle tube has the possibility of sudden temperature change, or the needle tube has higher temperature, so that the heat conducting gel is directly leaked and the like, but the scheme can not be used for keeping the temperature of the needle tube within a certain temperature range by the heat radiation of the fan-shaped radiation surface, so that the mounting difficulty is lower, the operation is more convenient, the work of other parts of the dispensing machine can not be influenced, and the dispensing operation can not be influenced; the outlet of the needle tube is not in the range of fan-shaped heat radiation, but still can be slightly influenced, so that the needle tube can not be gelled, and meanwhile, the arrangement can completely avoid heat transmission to 5G mobile phone parts, so that the arrangement is ingenious.
In addition, the mounting plate 1 of the present embodiment is provided with a battery jar 11, a battery 44 is arranged in the battery jar, and the battery and the heat conducting coil are connected in series. Of course, the electric control system of the electrical conductivity thermal gel device itself may be used for supplying power, and this embodiment does not limit this, as long as the electric heating coil can be powered to generate heat. In order to make the temperature of the needle tube more clear and more convenient for inspection, the outlet of the needle tube of the glue spraying valve 3 is provided with a temperature sensor, and the temperature sensor and the heat conducting coil can also be connected with an electric control system of the electric conduction thermal gelation device, so as to realize uniform control and maintain the temperature of the needle tube within a certain range (the technology is mature and is not described herein).
As a preferable scheme, the glue spraying valve 3 is a MARK glue spraying valve in germany, which can realize accurate control of glue amount, and the glue dispensing precision is less than or equal to 0.015 mm. Meanwhile, the glue spraying valve has an advanced 'suck-back' function, and can suck back glue remained outside the glue spraying valve needle pipe into the glue spraying valve needle pipe every time so as to prevent heat-conducting gel from blocking the glue spraying valve needle pipe due to the fact that the heat-conducting gel is remained outside and solidified. Of course, the gel spraying valve is easy to cause the gel to be condensed in the needle tube and block the needle tube because the heat conduction gel needs to be recycled. When adopting this kind to spout gluey valve, the cooperation this application modified hot reflux subassembly, its result of use is better.
In conclusion, the precision of the point heat-conducting gel can be greatly improved through a very simple improved structure, the precision requirement of the 5G mobile phone is met, the position, the quantity and the uniformity of the heat-conducting gel all reach the highest standard, the heat dissipation requirement of the 5G mobile phone is further met, and the practicability is very high.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
