[0043] The utility model is described in detail below in conjunction with the accompanying drawings.

[0044] Example 1

[0045] like Figure 1 to Figure 4As shown, the present application provides a coating fixture assembly for coating AVG30, the coating fixture assembly includes a tray 10 and a suction pen 20;

[0046] At least one mounting groove 110 is formed on the surface of the tray 10. The groove width of the mounting groove 110 is smaller than the outer diameter of the AVG 30. The mounting groove 110 is used for the AVG 30 to be suspended on the tray 10.

[0047] The suction pen 20 has a suction head 210 , and the suction head 210 is used to pass through the installation slot 110 and suck the AVG 30 from the lower surface of the AVG 30 . The suction pen 20 is used to take and place the AVG 30 .

[0048] During actual use, the AVG30 is placed upright on the surface of the tray 10, and the suction head 210 is inserted into the mounting groove 110 to suck the AVG30 from the lower surface of the AVG30. The AVG30 can be taken out and coated, which is easy to operate and will not scratch the upper surface of the AVG30. This provides a safe and reliable coating fixture for the new process of directly coating the AVG30.

[0049] In actual use, the friction between the lower surface of the AVG 30 and the upper surface of the tray 10 prevents the AVG 30 from being displaced on the tray 10 .

[0050] like Figure 3 and Figure 4 As shown, in this embodiment, the suction pen 20 further includes a negative pressure element and a pen body 220;

[0051] The suction head 210 has a suction port 211;

[0052] The pen body 220 has a negative pressure channel (not shown) for communicating with the suction head 210, and the two ends of the negative pressure channel are respectively used to communicate with the negative pressure element and the suction port 211 on the suction head 210;

[0053] When the negative pressure element is working, the suction head 210 sucks the AVG 30 through the suction port 211 .

[0054] In this embodiment, the two ends of the pen body 220 have a first connection portion 221 and a second connection portion 222 respectively, and the two ends of the negative pressure channel are connected to the negative pressure element and the suction port 211 on the suction head 210 through the first connection portion 221 and the second connection portion 222 respectively.

[0055] In this embodiment, a button switch 223 for controlling the suction pen 20 to suck and release is further provided between the first connection portion 221 and the second connection portion 222;

[0056] When the button switch 223 is pressed, the negative pressure channel is blocked, and the suction head 210 cannot suck the AVG30, so as to achieve the release of the AVG30;

[0057] When the button switch 223 is released, the suction head 210 sucks the AVG 30 to take out the AVG 30 .

[0058] In this embodiment, the second connection portion 222 is a connection tube.

[0059] The design of the connecting tube can reduce the volume of the entire suction pen 20, making it easier to take.

[0060] In this embodiment, the suction port 211 is located on the upper surface of the suction head 210;

[0061] The width of the suction head 210 is smaller than the width of the installation groove 110 , so that the suction head 210 can extend into the installation groove 110 .

[0062] In this embodiment, there are no sharp edges or corners between the structural surfaces of the suction head 210, and a smooth transition is provided to prevent the sharp edges from scratching the AVG 30.

[0063] In actual use, slight scratches on the lower surface of AVG30 do not affect the product yield.

[0064] In this embodiment, the mounting groove 110 is a sunken groove, and the thickness of the suction head 210 is smaller than the groove depth of the mounting groove 110 .

[0065] In this embodiment, the suction port 211 is located on the upper surface of the suction head 210 .

[0066] In this embodiment, the tip 210 is made of PI material that can withstand a high temperature of 400 degrees, and the pen body 220 is made of Peek material;

[0067] The tray 10 is made of aluminum alloy.

[0068] In this embodiment, the mounting groove 110 located on the surface of the tray 10 has a rounded corner or a chamfered corner.

[0069] In this embodiment, the closer the tip 210 is to the pen body 220 , the smaller the thickness of the tip 210 is, so as to facilitate the removal of the film.

[0070] In this embodiment, a plurality of mounting grooves 110 are formed on the surface of the tray 10 . The mounting grooves 110 are in a long strip structure and are arranged at intervals.

[0071] In actual use, the AVGs 30 are disposed above the mounting grooves 110 at intervals, and adjacent AVGs 30 do not contact each other.

[0072] A plurality of long strip-shaped installation slots 110 can ensure that the number of films placed is maximized, thereby improving production efficiency.

[0073] like Figure 4As shown, when multiple AVG30 are arranged on the surface of the tray 10, they are installed from right to left and from top to bottom. In this way, the AVG30 products can be placed to the maximum extent while ensuring that there is no contact between the AVG30 products.

[0074] In this embodiment, the thickness of the tray 10 is 3 mm;

[0075] The outer diameter of AVG30 is 32mm;

[0076] The depth of the mounting groove 110 is 2.5 mm, the width of the mounting groove 110 is 20 mm, and the interval between adjacent mounting grooves 110 is 20 mm;

[0077] The suction head 210 of the suction pen 20 is 10 mm wide and 2 mm thick.

[0078] In actual use, the depth of the mounting groove 110 is associated with the thickness of the suction head 210 , and the width of the mounting groove 110 is associated with the width of the suction head 210 , both of which are to enable the suction head 210 to move smoothly in the mounting groove 110 .

[0079] During actual use, hold the pen body 220 with your hand, press the button switch 223, insert the suction head 210 into the installation groove 110, align the suction port 211 with the lower surface of the AVG30, release the button switch 223, and let the suction head 210 suck the AVG30 under the action of the negative pressure element. At this time, the AVG30 can be removed from the tray 10, so that no scratches will be formed on the lower surface of the AVG30.

[0080] Example 2

[0081] The difference between this embodiment and the first embodiment is that in this embodiment, the installation groove is arranged to penetrate the tray along the groove depth direction, and at this time, the thickness dimension of the suction head is not limited by the groove depth dimension of the installation groove.

[0082] The above description is only a preferred embodiment of the utility model, and does not limit the patent protection scope of the utility model. Any equivalent structural transformation made using the contents of the utility model specification and drawings, directly or indirectly used in other related technical fields, is also included in the protection scope of the utility model.
