As shown in fig. 7, the second rotating mechanism 20 further includes a second supporting portion 22 and a second rotating portion 23, which are rotatably connected, and the second supporting portion 22 is used for supporting and fixing the second rotating portion 23. Specifically, the second support portion 22 may be plural. In the present embodiment, the second support portion 22 includes a second support portion 22a and a second support portion 22b respectively disposed at opposite sides of the second rotation portion 23 along the third direction 003.

The second rotating portion 23 includes a second rotating body 231 and a second rotating shaft 232, and the second rotating shaft 232 passes through the second rotating body 231 and is exposed in a third direction 003 in a direction away from the second rotating body 231 on opposite sides of the second rotating body 231. As shown in fig. 7, the second rotating body 231 is bridged between the second support portion 22a and the second support portion 22b in the third direction 003, and is rotatable with respect to the second support portion 22. Meanwhile, the second rotating shaft 232 is disposed at a distance from the mounting surface 41 along the second direction 002 to avoid the second rotating body 231 from colliding with the cabinet 40 and interfering with the cabinet when rotating.

Further, as shown in fig. 7, the second fixing member 21 is fixedly disposed on a side of the second rotating body 231 departing from the rotation center thereof, and rotates via the second rotating shaft 232, so as to drive the second rotating body 231 to rotate, and further drive the second fixing member 21 and the to-be-coated member 920 fixed on the second fixing member 21 to rotate. In the embodiment shown in fig. 7, the second fixing member 21 is plural, and the plural second fixing members 21 are arranged at intervals in the circumferential direction of the rotation direction of the second rotating mechanism 20. That is, as shown in fig. 7, the second rotating body 231 has a plurality of second fixing members (not shown), and a plurality of second fixing surfaces are sequentially and vertically connected in the circumferential direction of the rotating direction of the second rotating mechanism 20, and the number of the second fixing surfaces may be three, four, or more. In this embodiment, the number of the second fixing surfaces is four, and the second fixing members 21 are respectively fixed on the four second fixing surfaces.

In other embodiments, there may be one second fixing member 21. That is, when there is one second fixing member 21, the coating apparatus 100 of the present application may also perform coating of the second surface 922 by fixing the member to be coated 920 by the second fixing member 21.

In the present embodiment, the plurality of second fixing units 21 are independently controlled, that is, the plurality of second fixing units 21 disposed at different positions of the second rotating mechanism 20 are in a fixed state or a released state. For example, as shown in fig. 7, when the second fixing member 21a is located at the second coating position a2 and the second fixing member 21B is located at the second intersection B2, the second fixing member 21B fixes the member to be coated 920, and the other second fixing members 21 can release the member to be coated 920. The second rotating mechanism 20 controls the plurality of members to be coated 920 in a divisional manner by independently controlling the respective second fixing members 21.

As shown in fig. 7, the second fixing member 21 includes a second vacuum chuck 211, and in this embodiment, the second rotating shaft 232 is a vacuum rotating shaft, which can perform a vacuum pumping function when rotating. The second vacuum chuck 211 communicates with the second rotating shaft 232, and the second vacuum chuck 211 may be in two states including adsorption and release. Specifically, the second vacuum chuck 211 has a second opening 211a, the second opening 211a deviates from the rotation center of the second rotating mechanism 20, and the second opening 211a can abut against the first surface 921 and the second surface 922 of the to-be-coated member 920 to absorb or release the to-be-coated member 920, so as to fix or release the to-be-coated member 920. As can be appreciated, when the second vacuum chuck 211 is in the suction state, the second fixing member 21 fixes the member to be coated 920 by the second vacuum chuck 211; when the second vacuum chuck 211 is in the release state, the second fixing member 21 releases the member to be coated 920 by the second vacuum chuck 211.

The second fixing member 21 further includes a second groove 212, and the structural size of the second groove 212 is the same as that of the member to be coated 920. Specifically, as shown in fig. 7, the second groove 212 is opened on a side of the second fixing member 21 away from the second rotating body 231, and has a second bottom surface 212a, and the second vacuum chuck 211 is disposed on the second bottom surface 212a of the second groove 212. In the present embodiment, the second grooves 212 are multiple, and the multiple second grooves 212 are arranged in an array on the second fixing member 21. Second mounting 21 is through treating that coating piece 920 sets firmly in second recess 212 to through the second vacuum chuck 211 absorption treat coating piece, can carry on spacingly to fixed treat coating piece 920, in order to avoid treating that coating piece 920 takes place the displacement at coating or handing-over in-process, and then influence coating quality.

In one embodiment, the second fixing member 21 is detachably connected to the second rotating mechanism 20. In the embodiment, the second fixing member 21 is detachably connected with the second rotating mechanism 20, so that the second fixing member 21 can be replaced, and the coating device 100 of the present application can adapt to different sizes of the pieces to be coated 920.

The first fixing part 11 and the second fixing part 21 are arranged in a plurality of numbers, so that the first rotating mechanism 10 and the second rotating mechanism 20 can simultaneously fix or release a plurality of pieces 920 to be coated, and further, when the blade coating mechanism 30 coats the first surface 921 and/or the second surface 922, the first rotating mechanism 10 and the second rotating mechanism 20 can synchronously perform the handover process of the pieces 920 to be coated, so that the working efficiency of the coating device 100 is improved.

Further, in the present embodiment, the rotation directions of the first rotating mechanism 10 and the second rotating mechanism 20 are the same. In the embodiment shown in fig. 7, the coating apparatus 100 of the present application further includes a transmission mechanism 50 disposed between the first rotating mechanism 10 and the second rotating mechanism 20, and the first rotating mechanism 10 and the second rotating mechanism 20 are simultaneously rotated in the same direction by the transmission mechanism 50, that is, the first rotating mechanism 10 and the second rotating mechanism 20 can simultaneously rotate counterclockwise or simultaneously rotate clockwise. The transmission mechanism 50 may be a gear transmission, a hydraulic transmission, an electric transmission, or other manners or mechanisms. In the embodiment shown in fig. 7, the transmission mechanism 50 is a pulley structure, i.e. the pulley 51 is engaged with the belt 52 to realize the synchronous rotation of the first rotating mechanism 10 and the second rotating mechanism 20.

Specifically, as shown in fig. 7, the transmission mechanism 50 is located on the other side of the first rotating mechanism 10 away from the supporting frame 33 along the third direction 003, and further includes a driving motor 53. The driving motor 53 is fixedly disposed at an end of the first rotating shaft 132 away from the first rotating body 131, and the pulley 51a is fixedly disposed on the first rotating shaft 132 and located between the driving motor 53 and the first rotating body 131. A pulley 51b (not shown) is fixedly disposed at one end of the second rotating shaft 232 far away from the second rotating body 231, at least one pulley 51c is disposed between the pulley 51a and the pulley 51b, and the pulleys 51 are rotatably connected by a belt 52. That is, in this embodiment, the driving motor 53 drives the first rotating shaft 132 to rotate and simultaneously drives the pulley 51a fixed to the first rotating shaft 132 to rotate, and further, the pulley 51a drives the pulleys 51c and the belts 52 arranged between the pulley 51a and the pulley 51b to rotate synchronously, so that the second rotating shaft 232 and the first rotating shaft 132 rotate in the same direction, and thus the first rotating mechanism 10 and the second rotating mechanism 20 rotate synchronously and in the same direction.

In this embodiment, by setting the rotation directions of the first rotation mechanism 10 and the second rotation mechanism 20 to be the same, the member to be coated 920 can sequentially complete the processes of coating the first surface 921, interfacing the first surface 921 with the second surface 922, and coating the second surface 922.

Further, as shown in fig. 7, the first rotating mechanism 10 and the second rotating mechanism 20 are disposed on the mounting surface 41 along the first direction 001, and the first rotating mechanism 10 and the second rotating mechanism 20 are slidably connected along the first direction 001, that is, the first rotating mechanism 10 and the second rotating mechanism 20 can relatively move along the first direction 001. As shown in fig. 7, the coating apparatus 100 of the present application further includes a driving mechanism 60, and the driving mechanism 60 may be a telescopic hydraulic cylinder, a motor, or other structures or devices for driving the first rotating mechanism 10 and the second rotating mechanism 20 to move toward or away from each other. In the present embodiment, the driving mechanism 60 is disposed on a side of the second rotating mechanism 20 away from the first rotating mechanism 10 along the first direction, and is fixedly connected to the second rotating mechanism 20. Further, as shown in fig. 7, a fourth slide rail 411 is provided at a position where the mounting surface 41 faces the second support portion 22, and the fourth slide rail 411 extends in the first direction 001. The second supporting portion 22 is fixedly disposed on the fourth slide rail 411, so that the second rotating mechanism 20 can move along the fourth slide rail 411 relative to the first rotating mechanism 10.

That is, in the present embodiment, the driving mechanism 60 can drive the second rotating mechanism 20 to move along the fourth sliding rail 411 toward or away from the first rotating mechanism 10. Specifically, when the first rotating mechanism 10 and the second rotating mechanism 20 rotate, the driving mechanism 60 drives the second rotating mechanism 20 to move away from the first rotating mechanism 10 along the fourth sliding rail 411, so as to avoid the first rotating mechanism 10 and the second rotating mechanism 20 from colliding and interfering with each other during rotation. When the first rotating mechanism 10 drives the to-be-coated piece 920 to rotate to the first cross-over position B1 and the second rotating mechanism 20 drives the second fixing piece 21 to rotate to the second cross-over position B2, the driving mechanism 60 drives the second rotating mechanism 20 to approach the first rotating mechanism 10 along the fourth sliding rail 411, and the second fixing piece 21 abuts against the first surface 921 of the to-be-coated piece 920, so that the first fixing piece 11 can release the to-be-coated piece 920, and meanwhile, the second fixing piece 21 can fix the to-be-coated piece 920.

The coating apparatus 100 further includes a control module (not shown in the figure), which is disposed in the cabinet 40 and electrically connected to the first rotating mechanism 10, the second rotating mechanism 20 and the blade coating mechanism 30 respectively, for controlling the mutual cooperation of the first rotating mechanism 10, the second rotating mechanism 20 and the blade coating mechanism 30. Specifically, the control module comprises a processor, a position sensor and a pressure sensor. The processor can be a PLC controller, the position sensor can be a photoelectric sensor, and the pressure sensor can be a vacuum pressure sensor. Further, the position sensing device includes a first position sensing element for detecting a position state of the first fixing member 11 of the first rotating mechanism 10, a second position sensing element for detecting a position state of the second fixing member 21 of the second rotating mechanism 20, and a third position sensing element for detecting a position state of the doctor blade 31 and the steel mesh 32 in the doctor blade mechanism 30. The pressure sensor includes a first pressure sensing element for detecting a vacuum pressure value at the first opening 111a of the first vacuum chuck 111 and a second pressure sensing element for detecting a vacuum pressure value at the second opening 211a of the second vacuum chuck 211.

Specifically, the piece 920 to be coated is fixedly disposed on the first fixing element 11, and at this time, the first pressure sensing element detects a vacuum pressure value at the first opening 111a, that is, detects that the first vacuum chuck 111 is in an absorption state to fix the piece 920 to be coated. The first pressure sensing element transmits a signal of the vacuum pressure value at the first opening 111a to the processor, and the processor controls the first rotating mechanism 10 to rotate and drives the first fixing member 11 to rotate to the first coating position a 1. When the first position sensing member detects that the first fixing member 11 is located at the first coating position a1, a signal is transmitted to the processor. The processor receiving the signal controls the blade 31 of the blade coating mechanism 30 and the steel mesh 32 to approach the first rotating mechanism 10 along the second direction 002, and in this embodiment, the mesh opening 322a of the steel mesh 32 abuts against the first surface 921 of the member to be coated 920. After the third position sensing element detects that the steel mesh 32 abuts against the first surface 921 of the piece to be coated 920, a signal is transmitted to the processor, and the processor controls the scraper 31 to move relative to the mesh opening 322a along the first direction 001, so as to coat the coating 910 on the first surface 921 of the piece to be coated 920 through the steel mesh 32.

Further, after the coating of the first surface 921 is completed, in the present embodiment, the processor controls the second rotating mechanism 20 to move away from the first rotating mechanism 10 until the first rotating mechanism 10 and the second rotating mechanism 20 do not interfere with each other when rotating. Further, the first rotating mechanism 10 rotates and drives the to-be-coated member 920 to rotate to the first cross-connecting position B1, and meanwhile, the second position sensing element detects the position state of the second fixing member 21 and transmits a signal to the processor, and the processor controls the first rotating mechanism 10 to rotate and drives the second fixing member 21 to rotate to the second cross-connecting position B2. When the first fixing member 11 rotates to the first cross position B1 and the second fixing member 21 rotates to the second cross position B2, the processor controls the first fixing member 11 to release the member to be coated 920 and controls the second fixing member 21 to fix the member to be coated 920, and at this time, the second surface 922 of the member to be coated 920 is exposed.

The second pressure sensing element detects a vacuum pressure value at the second opening 211a, and the processor controls the second rotating mechanism 20 to be away from the first rotating mechanism 10 and controls the first rotating mechanism 10 and the second rotating mechanism 20 to rotate simultaneously. The second rotating mechanism 20 drives the fixed member to be coated 920 to rotate to the second coating position a2, and the processor controls the scraper 31 and the steel mesh 32 to approach the second rotating mechanism 20 along the second direction 002, i.e. in this embodiment, the mesh opening 322b abuts against the second surface 922 of the member to be coated 920. The processor controls the blade 31 to move in the first direction 001 with respect to the screen port 322b to apply the coating 910 on the first side 921 of the member to be coated 920 through the steel net 32, thereby completing the application of the first side 921 and the second side 922 of the member to be coated 920.

Referring to fig. 8, fig. 8 is a schematic view of a working scene of the member to be coated 920. In general, when the power device 930 such as an electronic component is operated, a large amount of heat is generated and needs to be transmitted to the outside through the heat dissipation housing 940 in real time. The heat-dissipating housing 940 is generally connected to the power device 930 through the member to be coated 920. At this time, if the power device 930, the to-be-coated member 920, and the heat dissipation housing 940 are directly assembled in sequence, there may be more gaps between the power device 930 and the to-be-coated member 920 and between the to-be-coated member 920 and the heat dissipation housing 940, which affects the heat dissipation efficiency of the power device 930, reduces the performance of the heat dissipation housing 940, and even makes the heat dissipation housing 940 unable to function. Therefore, it is possible to reduce contact thermal resistance by applying the coating material 500 on both sides of the member to be coated 920 for filling fine gaps between the power device and the member to be coated, and between the member to be coated and the heat dissipation case.

This application coating device 100 can realize that it is specific at the relative both sides face coating 910 that treat the piece 920 of coating automatically, through set up first fixed part 11 on first rotary mechanism 10 and fix and treat the piece 920 of coating to expose first face 921, so that when first rotary mechanism 10 rotated, can drive and treat that the piece 920 of coating stops in first application position A1 and first handing-over position B1 in proper order.

By arranging the second fixing member 21 on the second rotating mechanism 20, when the second rotating mechanism 20 rotates, the second fixing member 21 can be driven to be stopped at the second interface position B2 and the second coating position a2 in sequence. When the piece to be coated is located at the first intersection position B1 and the second fixing member is located at the second intersection position B2, the piece to be coated 920 is released by the first fixing member 11, the second fixing member 21 fixes the piece to be coated 920 and exposes the second surface 922, and then the process of joining the first surface 921 and the second surface 922 of the piece to be coated is completed.

Further, by arranging the blade coating mechanism 30 to be slidably connected to one side of the first rotating mechanism 10 and one side of the second rotating mechanism 20 along the second direction 002, so that the piece to be coated 920 is located at the first coating position a1, or when the piece to be coated 920 is located at the second coating position a2 by the second fixing member 21, the blade coating mechanism 30 can slide and approach to the piece to be coated 920 to coat the coating 910 on the first surface 921 or the second surface 922, thereby completing the coating process of the first surface 921 and the second surface 922 of the piece to be coated 920.

Further, the coating device 100 can realize a full-automatic process of coating the first surface 921 and the second surface 922 of the piece 920 to be coated, so as to improve the coating efficiency of the piece 920 to be coated and the coating precision of the coating 910.
