[0033] When in use, the pallet is placed on the supporting structure, and then the core 100 to be coated with glue is placed on the pallet, and the flipping mechanism arranged at the supporting structure is controlled to lift the pallet and flip it 180°, and then the pallet is grabbed by the grabbing mechanism, and the electric slider 42 is controlled to move along the length direction of the guide rail 41 to be directly above the base 2, and then the pallet is controlled to move downward until the core 100 is inserted into the gluing mechanism to complete the gluing operation.

[0035] Among the above, Figure 5-7 The glue coating mechanism includes an integrally formed shell, which includes a shell A10 located at the upper part and a shell B1 located at the lower part, and the inner diameter of the shell A10 is smaller than the inner diameter of the shell B1, and the bottom end of the shell B1 is provided with a flange 13 protruding outward; the bottom side surface of the support ring 12 is connected to a plurality of positioning columns 122; the bottom end of the shell B1 is connected to a collecting groove 14, and the bottom side surface of the collecting groove 14 is provided with a positioning sleeve 142 that cooperates with the positioning column 122, and the bottom side surface of the positioning sleeve 142 is connected to a movable column that slides along the inner wall of the positioning sleeve 142 through a spring A143 144. During installation, the bottom end of the positioning column 122 abuts against the movable column 144; a convex tube 121 is provided on one side of the support ring 12, and the positioning column 122 is located on the outer peripheral side of the convex tube 121; a discharge port 141 is provided on the bottom side surface of the collecting tank 14, and a cover plate is detachably connected to the discharge port 141; when in use, the glue coating mechanism is placed inside the accommodating cavity 20, and the end of the abutment structure 211 provided on the fixing unit 21 abuts against the flange 13; the abutment structure 211 is a bolt threadedly connected to the fixing unit 21, or an abutment column provided on one side of the fixing unit 21.

[0036] Based on the above, in order to facilitate the overall installation of the fixing unit 21, any two adjacent fixing units 21 in the device are connected by a connecting rod 22, and the fixing unit 21 and the connecting rod 22 are connected to form an integral part; and a cross bar 23 is connected to the fixing units 21 on both edge sides of the integral part, and an insertion rod 231 is provided at the end of the cross bar 23, and a socket 201 for inserting the insertion rod 231 is provided on the upper surface of the base 2, and the outer wall of the base 2 is threadedly connected to the fastening bolt 202.

[0037] At the same time, in order to facilitate the use of the provided glue coating mechanism to evenly coat the core 100 inserted therein, as shown in FIG. Figure 5-7 A step portion is formed at the joint of the provided shell A10 and the shell B1; a silicone grease storage chamber 101 is provided in the shell A10, and two heating chambers 102 are also provided in the shell A10 located on both sides of the silicone grease storage chamber 101, and the silicone grease storage chamber 101 and the heating chamber 102 are both annular structures; the top of the silicone grease storage chamber 101 is protruding, and a perfusion pipe 104 is connected to one side wall, and a plurality of openings 103 are provided on the bottom side of the silicone grease storage chamber 101; a glue coating module 11 is abutted at the step portion; when in use, the core 100 is inserted from the top of the shell A10 into the core 1 00 contacts the inner peripheral side wall of the glue coating module 11, and the silicone grease attached to the glue coating module 11 is coated on the outer peripheral side wall of the core 100; when in use, the liquid silicone grease stored in the silicone grease storage chamber 101 forms a fluid state under the heating state, and the silicone grease in the fluid state flows from the opening 103 to the outside to the glue coating module 11 under the action of gravity, and makes the entire glue coating module 11 evenly adhered to the silicone grease, and then when the core passes through the glue coating module 11, the silicone grease adhered to the glue coating module 11 is evenly coated on the outer peripheral side wall of the core 100, thereby completing the gluing operation.

[0038] The purpose of the two heating chambers 102 mentioned above is to keep the silicone grease storage chamber 101 in a high temperature state to avoid a decrease in the fluidity of the silicone grease stored in the silicone grease storage chamber 101 after the temperature drops, resulting in the silicone grease being unable to penetrate the entire gluing module 11; at the same time, in order to facilitate the use of the gluing module 11 to gluing the core 100, the provided gluing module 11 is an annular sponge block or an annular brush, and a support ring 12 is connected to one side of the gluing module 11, and the inner diameter of the support ring 12 is smaller than the inner diameter of the shell A10.

[0042] In order to facilitate the matching and support of the pallet, the support structure includes a base plate 5 installed on the working platform 4, a plurality of positioning sleeves 51 are arranged on the upper surface of the base plate 5, and a support column 33 inserted into the positioning sleeve 51 is arranged on one side of the base plate 3.

Rectangular holes 34 for inserting the rectangular column 64 are provided on the opposite sides of the substrate 3. When in use, the connecting frame 62 is controlled to be sleeved on the outer wall of the substrate 3, and then the clamping cylinder 63 is controlled to extend to the rectangular column 64 and insert into the rectangular hole 34, and then the rotary motor 61 is controlled to rotate to complete the control of the substrate 3 to flip.
