Description

Technical Field

[0001] The utility model relates to the technical field of jigs, in particular to a flip jig used for sponge tape application. Background Art

[0002] Sponge tape is primarily made of polyurethane (PU) or polyethylene (PE), with EVA foam as the backing, coated on one or both sides with solvent (or hot-melt) pressure-sensitive adhesive, and then backed with an easily removable release paper. Due to its unique structure and material properties, it is widely used in various applications requiring bonding, fixing, or protection, such as packaging, fixing, and protecting electronic components.

[0003] Currently, the electronics industry generally applies sponge tape in two ways: purely manual or machine-assisted. A sponge tape applying machine is one of these machines. At the same time, this machine is generally equipped with a pressure-holding mechanism to maintain pressure after application to ensure application strength. Currently, the pressure-holding and application processes are both performed on a set of jigs. There is manual participation during application, while pressure-holding is a purely machine action. During pressure-holding, there is a risk of injury if a worker's limbs accidentally enter the pressure-holding area. Utility Model Content

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0029] See also Figure 1-7 , a flip jig for sponge tape application, including a back plate 1, the back plate 1 is tilted vertically backward, the tilt angle of the back plate 1 is 10 °, the left and right positions of the bottom of the back plate 1 are provided with brackets 4, the back plate 1 is fixed to the bracket 4 at the corresponding position by bolts, and a shaft 5 is installed on the bracket 4 through a bearing sleeve, a flap 6 is provided on the front side of the back plate 1, and clamps 11 are bolted on the left and right sides of the bottom of the flap 6 corresponding to the bracket 4. The clamp 11 clamps the shaft 5 to form a rotating movable fixation, a handle 12 is bolted on the top edge of the flap 6, and a fixing part 7 is bolted on the bottom surface of the flap 6 facing away from the back plate 1 near the top edge. Pneumatic vacuum suction cups 8 are installed at both ends of the fixing part 7, and the sponge tape body 15 is adsorbed and fixed at the position of the pneumatic vacuum suction cup 8;

[0030] A pad 13 is provided at the lower front side of the backing plate 1 corresponding to the horizontal position of the flip plate 6. A workpiece placement fixture 14 is installed on the top surface of the pad 13 by bolts. Guide rail sliders 16 are bolted on the left and right sides of the bottom of the pad 13. Guide rails 18 are passed through the guide rail sliders 16. The bottom of the guide rail 18 is fixed to the rail seat 17 set at the corresponding position by bolts. A screw rod 19 is provided at the lower middle position of the pad 13. The two ends of the screw rod 19 are sleeved on the shaft seat 20 set at the corresponding position to form a set fixation. A screw motor 21 is bolted on the middle position of the bottom of the pad 13, and the screw motor 21 is connected to the screw rod 19 for transmission.

[0031] When in use, place the workpiece to be attached with sponge tape on the workpiece placement fixture 14, take the sponge tape to be attached to the position of the pneumatic vacuum suction cup 8, fix it by negative pressure adsorption, and then hold it from the handle 12 position, and use the socket rotation fixed relationship between the flap 6 and the shaft 5 to pull the flap 6 to flip it to the front and bottom so that it is buckled onto the workpiece. At this time, the sponge tape can be attached to the surface of the workpiece through its own adhesive, and at the same time, the pneumatic vacuum suction cup 8 is exhausted and no longer attracts the sponge tape, and the pasting operation can be completed at this time. After the pasting is completed, the screw motor 21 is controlled to work, so that it uses the transmission relationship with the screw 19 and relies on the support of the guide rail 18 and the guide rail slider 16 to drive the entire pad 13 to move backward, and form an internal pasting pressure compensation device in the guide rail 18 on the rear side of the support plate 1, which can compensate the pressure on the sponge tape to ensure the firmness of the adhesion.

[0032] In this embodiment, positioning rods 2 are installed at the left and right middle positions of the front side of the backrest 1, and positioning cylinders 9 are installed on the top surface of the flap 6 facing the backrest 1 at the position corresponding to the positioning rod 2. The positioning rod 2 is pushed into the positioning cylinder 9 to form a positioning limit. Positioning blocks 3 are installed on the left and right sides of the top of the front side of the backrest 1, and positioning holes 10 are preset on the flap 6 at the positions corresponding to the positioning blocks 3. The positioning blocks 3 are pushed into the positioning holes 10 to form a positioning limit.

[0033] The combination of the positioning rod 2 and the positioning cylinder 9 as well as the positioning block 3 and the positioning hole 10 enables the flap 6 to obtain a positioning and restraining effect when it is lifted to lean against the backrest plate 1 .

[0034] In this embodiment, a fixing block 22 is installed on the front side of the pad 13. A limiting rod 23 is installed on the side of the fixing block 22 facing the pad 13. The end of the limiting rod 23 reaches the middle position of the front side of the pad 13 to form a limit.

[0035] The limit rod 23 is used to prevent the screw motor 21 from driving the lower pad 13 to move too far and dislocate, so that it can be kept at the required position to ensure that the sponge tape body 15 can be attached to the correct position of the workpiece after the flap 6 is flipped down.
