Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical automation and relates to a paste coating device and paste coating equipment for coating heat dissipation paste and other materials for components such as radiators. Background Art

[0002] At present, the transformation and development of automated equipment has become the main trend of manufacturing development. In modern manufacturing, mechanical devices such as automatic loading, automatic processing, and automatic assembly are widely used to replace manpower to complete most production links, so as to achieve the purpose of reducing labor costs and realizing automated production. Taking air-conditioning manufacturing companies as an example, major domestic air-conditioning manufacturers currently need to realize the automatic handling and transfer of production materials in some positions of the manufacturing line during the production of air-conditioning parts, so as to improve the automation rate of the production line, improve production efficiency, and reduce labor costs.

[0003] However, there are still some processing links that cannot be fully completed by automated machinery. In other words, although there are corresponding mechanical devices to complete them, there is still much room for improvement in the degree of automation and processing efficiency.

[0004] For example, the thermal paste is applied to the surface of components such as radiators. Specifically, the mainboard components need to be equipped with radiators to meet the heat dissipation requirements, and the contact part between the radiator and the mainboard electronic components needs to be brushed with thermal paste to improve the heat dissipation efficiency of the components; however, the current method of applying thermal paste on the surface of the radiator is mainly to manually place the printed mesh component on the surface of the radiator and other components, and then manually apply the paste and manually drive the brush knife to reciprocate to evenly apply the paste. Obviously, the manual operation method is inefficient, and the quality of thermal paste coating is difficult to accurately control, which seriously restricts the production efficiency of the entire production line.

[0005] For another example, for processed devices such as heat sinks, they need to be positioned before processing operations such as applying paste, and the current automation level of the relevant machinery in the positioning link is not high enough. Taking the positioning of the heat sink before applying paste as an example, when the heat sink to be processed is loaded onto the positioning support table, although a limit mechanism is set on the positioning support table, it is still necessary to manually move the heat sink and stop it at the limit mechanism, which has low operating efficiency and poor consistency. In addition, the loading and unloading links of the relative positioning support table currently mainly use the method of robot grasping, which has relatively low efficiency and power consumption.

In addition, the paste coating device provided in the first embodiment also includes a fifth driving component 92 that drives the fourth driving component 91 to move forward and backward. The fourth driving component 91 and the fifth driving component 92 are both realized by a screw mechanism driven by a motor in cooperation with a guide mechanism.

[0087] The paste coating device provided in the first embodiment drives the second bearing component 30 through the first driving component 20 to drive the printing screen component 40 to move up and down, so that the printing screen component 40 can be quickly positioned above the device 900 to be coated with paste; the brush knife component 70 is driven up and down by the second driving component 50, thereby automatically controlling the lowering and retracting of the brush knife component; the brush knife component 70 is driven left and right by the third component 60 to complete the brushing of the paste and ensure the uniformity of the brushing; in addition, the automatic paste feeding component 80 is set, which can automatically and quantitatively provide paste to the brush knife component 70 and the printing screen component 40.

Therefore, as an extended implementation, the paste application equipment provided in this embodiment also includes: a device positioning device 400, which is arranged at the paste application station and is used to position the device below the paste application device. By setting the device positioning device 400, the device 900 to be applied with paste can be accurately positioned below the printing screen assembly of the paste application device. In addition, as a further extended implementation, this embodiment also sets a device unloading device 500, which can quickly unload the device 900 that has been applied with paste. Moreover, an electric control cabinet 204 and a storage cabinet 206 are also provided in the first frame 201. The electric control cabinet 204 is used to centrally control various actions of the paste application device 100, the conveying device 300, the device positioning device 400, and the device unloading device 500. In addition, a control panel 205 and a warning light 207 that interact with the electric control cabinet 204 are also provided on the third frame 203.

[0093] Combination Figure 6 and Figure 7As shown, the device positioning device 400 includes: a device carrying component 410, a limiting component 420 and a positioning component 430; the device carrying component 410 is used to receive the device 900 conveyed by the conveying device 300, the limiting component 420 is arranged on the device carrying component 410 and is used to upper limit a device stop position on the device carrying component 410; the positioning component 430 is arranged on the device carrying component and is used to move and position the device 900 on the device carrying component 410 to the device stop position.

[0094] Among them, the device carrier assembly 410 includes a device positioning carrier plate 411, the limiting assembly 420 includes a front limiting mechanism 421 and a right limiting mechanism 422; the positioning assembly 430 includes a rear pushing mechanism 431 that can move forward and backward relative to the front limiting mechanism 421 and a left toggle mechanism 432 that can move left and right relative to the right limiting mechanism 422.

[0095] As an optional embodiment, the front limiting mechanism 421 is a front stopper 4211 fixedly disposed on the device bearing assembly 410 for stopping the device 900 from moving forward. The right limiting mechanism 422 can also be a right stopper fixedly disposed on the device bearing assembly 410 for stopping the device 900 from moving rightward.

[0096] The rear pushing mechanism 431 includes a second linear module 4311 and a pushing member 4312. The second linear module 4311 is arranged in the front-to-back direction above the device carrier assembly 410, and the right end of the pushing member 4312 is fixedly connected to the slider of the second linear module 4311. More specifically, the pushing member 4312 includes an L-shaped pushing plate 43121 and a clamping plate 43122. The clamping plate 43122 has a longitudinal clamping surface for clamping the device 900 to the front stopper 4211. In addition, the rear pushing mechanism 431 also includes a second guide mechanism 4313, which is arranged in the front-to-back direction above the device carrier assembly, and the pushing member 4312 is slidably supported on the second guide mechanism.

[0097] The left toggle mechanism 432 includes a fourth cylinder 4321 and a toggle member 4322. The fourth cylinder 4321 is arranged on the pusher 4312 in a left-right direction, and the toggle member 4322 is connected to the cylinder arm of the fourth cylinder 4321. More specifically, the toggle member 4322 is a toggle rod arranged in a front-to-back direction, with its rear end fixedly connected to the cylinder arm of the fourth cylinder 4321, and its front end used to toggle the device 900 rightward.

[0098] In the above optional implementation manner, when limiting the position of the device 900 to be coated with paste, the front stopper 4211 and the right stopper define the device stop position; when the device 900 to be coated with paste is conveyed to the device supporting assembly 410 through the conveying device 300, the rear pushing mechanism 431 and the left toggle mechanism 432 respectively push the device 900 forward and toggle it to the right, so that the device 900 is positioned at the device stop position; when the device 900 on the device supporting assembly 410 completes the paste coating operation, the rear pushing mechanism 431 and the left toggle mechanism 432 reset backward and left respectively; at this time, the device 900 after the paste coating is completed is unloaded manually or by a robot.

[0099] As another optional embodiment, in order to make the right-side limiting mechanism 422 have both a stopping function and an auxiliary function of material feeding after applying the paste, the right-side limiting mechanism 422 includes a third linear module 4221 and a right-side push block 4222. The third linear module 4221 is arranged in a left-right direction on the front side above the device supporting assembly 410, and the front end of the right-side push block 4222 is fixedly connected to the slider of the third linear module 4221.

[0100] In the above-mentioned another optional embodiment, when limiting the device 900 to be coated with paste, the third linear module 4221 fixes the right push block 4222 at the right stop position, and the right push block 4222 is used for limiting; when the device 900 to be coated with paste is conveyed to the device supporting assembly 410 through the conveying device 300, the rear pushing mechanism 431 and the left toggle mechanism 432 respectively push the device 900 forward and toggle the device 900 to the right, so that the device 900 is positioned at the device stop position; when the device 900 on the device supporting assembly 410 completes the paste coating operation, the rear pushing mechanism 431 and the left toggle mechanism 432 reset backward and to the left respectively; at this time, the third linear module 4221 of the right limiting mechanism 422 drives the right push block 4222 to move to the left, thereby pushing the device 900 after the paste coating is completed to the left.

[0101] Continue to see Figure 6 and Figure 7In this embodiment, the height of the device positioning carrier plate 411 is higher than the height of the conveying surface of the conveying device 300; the device bearing assembly also includes a lifting mechanism 412, which is arranged at the junction of the conveying device and the device bearing assembly. Specifically, the lifting mechanism includes a fifth cylinder 4121 and a tray 4122, the fifth cylinder 4121 is arranged on the rear side of the device positioning carrier plate 411 with the cylinder arm facing upward, and the tray 4122 is connected to the cylinder arm of the fifth cylinder 4121 and moves up and down between the upper surface of the device positioning carrier plate 411 and the conveying surface of the conveying device 300. In this way, the device 900 transmitted to the front end of the conveying device 300 first falls on the lifting mechanism 412, and then is lifted by the lifting mechanism 412 to the same height of the device positioning carrier plate 411, and then pushed forward by the rear side pushing mechanism 431. Such a design can simplify the design of the rear side pushing mechanism 431, that is, the rear side pushing mechanism 431 only needs to move forward and backward.

[0102] Of course, the lifting mechanism 412 may not be provided, so that the upper surface of the device positioning support plate 411 is flush with the conveying surface of the conveying device 300; in this case, the pushing member 4312 of the rear pushing mechanism 431 needs to go around the rear of the device 900 before it can be pushed forward; in this way, the pushing member 4312 of the rear pushing mechanism 431 also needs to be configured with a driving mechanism to drive its up and down movements, and the structural design will be relatively complicated.

[0103] Continue to see Figure 6 and Figure 7 , the device unloading device 500 is arranged on the left side of the device carrying component 410, and the device unloading device 500 includes a device temporary storage carrier plate 501, a material unloading conveying component 502 and a material pushing component 503. The device temporary storage carrier plate 501 is used to receive the device 900 that has been coated with paste on the device positioning carrier plate 411; wherein, the device 900 that has been coated with paste can be transferred by a device transfer component such as a robot, or the third linear module 4221 of the right side limit mechanism 422 mentioned above drives the right side push stopper 4222 to move to the left, so as to push the device 900 that has been coated with paste to the left to the device temporary storage carrier plate 501. In addition, the material pushing component 503 is used to push the device 900 from the device temporary storage carrier plate 501 to the material unloading conveying component 502 for unloading.
