As shown in fig. 2, 4 and 5a, the electronic control system 10 in the embodiment is electrically connected to each transmission structure of the automatic coating device 100, specifically including the air cylinder 43, the first motor 231, and the like.

In this embodiment, the automatic coating apparatus 100 is divided into a coating zone and a loading zone by the design of the protective cover 30. The components of the loading zone mainly complete the loading and feeding process of the electronic device 200, and the components of the coating zone mainly perform the coating operation on the electronic device 200. Therefore, the feeding process and the coating process are separated, so that sputtering pollution of the heat-conducting silicone grease to the periphery is prevented when the electronic device 200 is coated; on the other hand, the protective cover 30 also prevents dust and debris from the outside from being mixed into the heat conductive silicone grease, which affects the coating effect of the electronic device 200.

In one embodiment, as shown in fig. 5a and 7, the protective cover 30 is provided with a rotatably connected observation window 31, and the observation window 31 is positioned above the steel mesh coating plate 51. The viewing window 31 is designed to facilitate visual understanding of the working conditions of the coating zone components by the worker and to facilitate control of the process flow. For example, when the electronic device 200 is transferred to the coating area through the jig base plate 42, and then the first motor 231 and the second motor 232 operate to adjust the position of the coating knife 22 in the first direction and the second direction, the operator operates the electronic control system to change the position of the coating knife 22 in different directions by observing the positional relationship between the coating knife 22 and the steel mesh coating plate 51.

Specifically, in order to facilitate the observation of the working condition of the coating area through the observation window 31, as shown in fig. 7, the observation window 31 is opened on the panel 32 which forms an angle of 15 degrees to 75 degrees with the working plate. The observation window 31 is arranged on the panel 32 forming an included angle with the working plate, so that the worker can simultaneously obtain the main viewing angle and the overlooking viewing angle of the coating area, and the feeding and retracting operations of the coating knife 22 are more accurate.

In one embodiment, as shown in FIG. 7, the viewing window 31 is adapted to be switchable closed and an electronic switch (not shown) is provided to lock the viewing window 31 when the automatic coating apparatus 100 is in operation. The observation window 31 is designed to be in a switchable mode, so that a worker can clean the components of the coating area regularly, and particularly, the observation window 31 is pivoted on the panel 32. Meanwhile, the automatic coating device 100 coats the electronic product through the coating knife 22, in order to avoid danger in the operation process, an electronic switch is arranged on the observation window 31, and when the coating process is started, the electronic switch can lock the observation window 31, so that misoperation of workers is avoided.

In a specific embodiment, as shown in fig. 5a and 5b, the coating blade 22 includes a left coating blade 221 and a right coating blade 222, and the left coating blade 221 and the right coating blade 222 are moved in a first direction and a second direction by the positioning system 23. In the actual coating process, the left and right coating blades 221 and 222 are connected to a transfer tray 235. Under the drive of the positioning system 23, the left coating knife 221 and the right coating knife 222 are adopted to perform heat-conducting silicone grease coating on the electronic device, so that the coating efficiency can be improved.

In a specific embodiment, as shown in fig. 5b and 6a, a pressure cylinder 24 is further provided between the coating knife 22 and the positioning system 23, the coating knife 22 is moved in the second direction by the pressure cylinder 24, and the pressure cylinder 24 is controlled by the electronic control system. Specifically, as shown in fig. 5a and 5b, the left and right coating knives 221 and 222 of the coating knife 22 are provided with pressure cylinders 24, respectively, left and right pressure cylinders 241 and 242 at the connection with the transfer plate 235 of the positioning system 23. The left coating knife 221 is connected with the conveying disc 235 through a left pressure air cylinder 241, the right coating knife 221 is connected with the conveying disc 235 through a right pressure air cylinder 242, and the pressure air cylinder 24 is used for driving the coating knife 22 to move differentially in the second direction, namely, the joint between the single coating knife 22 and the steel mesh coating plate 51 in the coating process is realized.

In a specific operation process, the left coating knife 221 and the right coating knife 222 are sent to a proper position above the steel mesh coating plate 51 by the conveying disc 235, and then the left pressure cylinder 241 drives the left coating knife 221 downwards along the second direction to realize the pressure fit of the left coating knife 221 and the steel mesh coating plate 51; the right pressure cylinder 242 drives the right coating blade 222 upward in the second direction to separate the right coating blade 222 from the steel mesh coating panel 51, thereby achieving the secondary positioning of the coating blade 22 in the second direction. Then, the electronic control system 10 controls the first motor 231 to operate, and the first motor 231 drives the driving transfer plate 235 to move from left to right along the first direction through the transfer belt 233, so that the first coating of the steel mesh coating plate 51 by the left coating blade 221 from left to right is realized, and when the driving transfer plate 235 moves from the left side to the right side of the steel mesh coating plate 51, the first coating work is completed.

Next, the left pressure cylinder 241 drives the left coating blade 221 to move upward along the second direction, so as to separate the left coating blade 221 from the steel mesh coating plate 51, and the right pressure cylinder 242 drives the right coating blade 222 to move downward along the second direction, so as to press-fit the right coating blade 222 to the steel mesh coating plate 51. Then, the electronic control system 10 controls the first motor 231 to operate, drives the transfer plate 235 to move from right to left in the first direction, thereby performing a second coating of the steel mesh coating panel 51 from right to left by the left coating blade 221, and completes the second coating work when the transfer plate 235 is driven to travel from right to left of the steel mesh coating panel 51.

By the first coating of the left coating knife 221 and the second coating of the right coating knife, the area to be coated of the electronic device can be uniformly and completely coated with the heat-conducting silicone grease. It should be noted that the pressure cylinder 24 can perform secondary adjustment on the position of the coating knife 22 according to the blocked pressure, so as to achieve better coating effect. For example, taking the left coating knife 221 as an example of downward feeding, after the left coating knife 221 completes one positioning in the second direction under the driving of the second motor 232, at this time, there is no contact between the left coating knife 221 and the steel mesh coating plate 51, at this time, the left pressure cylinder 241 can detect that downward feeding is needed according to the blocked pressure, and when the contact between the left coating knife 22 and the steel mesh coating plate 51 generates relative resistance after feeding to a certain position, the left pressure cylinder 241 can determine whether to continue feeding according to a preset value; similarly, after the left coating knife 221 completes the positioning in the second direction under the driving of the second motor 232, the left coating knife 221 contacts with the steel mesh coating plate 51 to generate a large pressure, the left pressure cylinder 241 can detect the need to retract upward according to the blocked pressure, and after the tool retracts to a certain position, the left pressure cylinder 241 can judge whether the tool needs to continue to retract according to the preset pressure value.

In a specific embodiment, as shown in fig. 5b, an angle fine adjustment screw 223 is provided on the coating blade 22, and the angle fine adjustment of the coating blade 22 is realized by the angle fine adjustment screw 223. In the actual operation process, the heat conductive silicone grease is pressed into the meshes of the steel mesh coating plate 51 by the blade edge of the coating blade 22 moving back and forth along the first direction, and then is uniformly coated on the area to be coated of the electronic device 200. Specifically, the angle fine adjustment screw 223 disposed on the left coating knife 221 allows the blade edge of the left coating knife 221 to incline to the left, so that when the first motor 231 drives the left coating knife to perform the first coating from the left to the right, the blade edge of the left coating knife 221 can press the heat-conductive silicone grease. Similarly, the angle fine adjustment screw 223 disposed on the right coating knife 222 allows the blade of the right coating knife 222 to tilt to the right, so that when the first motor 231 drives the right coating knife to perform the second coating from right to left, the pressing effect of the blade of the right coating knife 222 on the heat-conducting silicone grease can be achieved.

In one embodiment, as shown in fig. 6a, the length of the steel mesh support rod 52 can be adjusted to achieve the position adjustment of the steel mesh coating plate 51 in the second direction. One end of the steel mesh support rod 52 is connected with the steel mesh coating plate 51, and the other end is connected with the working plate 61; the length of the steel mesh support rod 52 determines the height of the steel mesh coating panel 51. Because the height of the electronic device depends on the height of the jig base plate 42 and the transmission base 41, and the height of the jig base plate 42 and the transmission base 41 is difficult to change once being fixed, the steel mesh support rod 52 with adjustable length can ensure that the lower plate surface (not shown in the figure) of the steel mesh coating plate 51 is better attached to the surface to be coated of the electronic device.

In a specific embodiment, as shown in fig. 6a, the steel mesh support rod 52 comprises a support guide 521 connected with the steel mesh coating plate 51 and a guide rod bearing 522 connected with the working plate, a jacking cylinder 53 is further connected between the steel mesh coating plate 51 and the working plate 61, and the jacking cylinder 53 is controlled by an electronic control system. The support guide 521 interfaces with the guide bar bearing 522 such that the support guide 521 can slide within the guide bar bearing 522, thereby ensuring that the length of the entire steel mesh support bar 52 can be adjusted. And the jacking cylinder 53 disposed between the steel mesh coating plate 51 and the working plate 61 can provide a jacking force in the second direction to the steel mesh coating plate 51, and the height of the steel mesh coating plate 51 can be adjusted by adjusting the jacking force to change the length of the steel mesh support rod 52. In other embodiments, the height of the steel mesh coating plate 51 can be adjusted by using a threaded connection, that is, the steel mesh support rod 52 is composed of two threaded rods with two threads in butt joint, and the length of the steel mesh support rod can be changed by rotating the threaded rods.

In one embodiment, as shown in FIGS. 6a and 6b, the steel mesh assembly 50 further includes a steel mesh supporting plate 54, the steel mesh coating plate 51 is detachably mounted on the steel mesh supporting plate 54, and the steel mesh supporting plate 54 is connected to the steel mesh supporting rod 52. In an actual operation process, in order to facilitate the cleaning of the steel mesh coating plate 51, the steel mesh coating plate 51 is detachably disposed on the steel mesh supporting plate 54, and then the steel mesh supporting plate 54 is connected to the steel mesh supporting rod 52. When the steel mesh coating plate 51 needs to be cleaned or replaced, the used steel mesh coating plate 51 is only required to be taken down from the steel mesh bearing plate 54, and the steel mesh support rod 52 does not need to be disassembled, thereby greatly simplifying the cleaning or replacing time.

The positioning blocks 541 are fixed on the steel mesh bearing plate 54 and enclose an area for placing the steel mesh coating plate 51. The positioning block 541 is provided with an elastic pressing block 542 connected with the positioning block 541, and after the steel mesh coating board 51 is placed in the area limited by the positioning block 541, the elastic pressing block 542 is pressed on the edge of the steel mesh coating board 51, so that the steel mesh coating board 51 is fixed.
