Detailed Implementation
[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments;
[0026] This embodiment provides a product adhesive film application fixture, including a first base plate 1, which is a base platform made of metal. A lower mold base 2, also made of metal, is fixed to the upper surface of the first base plate 1. A first limiting pit 20 is formed by a recess in the middle of the lower mold base 2. The sidewall of the first limiting pit 20 extends to the edge of the lower mold base 2, and the first limiting block can hold the adhesive film 100. The inner surface of the first limiting pit 20 matches the outer contour of the adhesive film 100. The first limiting pit 20 extends out of the lower mold base 2, which serves as a non-displacement mechanism to facilitate the placement of the adhesive film 100 by fingers.
[0027] The first base plate 1 is provided with two first guide posts 3, and a first moving plate 4 is sleeved between the two first guide posts 3. The first moving plate 4 is fixed to the first guide posts 3 by friction. The two first guide posts 3 are set on both sides of the lower mold base 2. The first moving plate 4 is a metal plate that is fixed to the first guide post 3 by friction. That is, the first moving plate 4 is stuck on the first guide post 3. It is necessary for the employee to manually push it up and down to move the first moving plate. The first moving plate 4 will not automatically descend on the first guide post 3.
[0028] The first sliding plate 4 is provided with an upper mold base 5, which is also a metal block; bolts are screwed into the first sliding plate 4 and the upper mold base 5 for fixation; the lower surface of the front end of the upper mold base 5 is recessed to form a second limiting pit 50, which can hold the end cap product 200; a first air hole 51 is provided around the second limiting pit 50, which is used for gas to flow through.
[0029] The upper surface of the front end of the upper mold base 5 is recessed to form a first recess 52, and the bottom surface of the first recess 52 communicates with the first air hole 51; the rear end of the upper mold base 5 is provided with a second air hole 53, and the side of the first recess 52 communicates with the second air hole 53; the second air hole 53 is screwed into the threaded air nozzle 6, and the air nozzle 6 is connected to the air pump through the air pipe; the air pump is powered on to draw air, and the gas is drawn out from the first air hole 51, the first recess 52, and the second air hole 53 and flows through, and a negative pressure suction is formed below the first air hole 51.
[0030] The end cap product 200 can be adsorbed onto the first air hole 51 of the lower mold base 2. The first moving plate 4 is manually moved down, and the end cap product 200 and the adhesive film 100 are attached and fixed.
[0031] As described above, the specific usage process involves peeling the adhesive film 100 from the release paper and placing it upside down, adhesive side up, into the first limiting pit 20 of the lower mold base 2. The vacuum pump continuously draws air, and the upper mold base 5 is initially positioned at the top of the first guide post 3. The outer surface of the end cap product 200 to be adhered to is facing down. The end cap product 200 is placed in the second limiting pit 50 for adhesion and fixation. The first moving plate 4 is manually pressed downwards, squeezing the end cap product 200 and adhesive film 100 together until they are bonded. Once bonding is complete, the upper mold base 5 is manually moved upwards for the next application. The end cap product 200 can then be retrieved. This process saves employees the labor involved in bonding; employees only need to place the adhesive film 100 and the end cap product 200, saving physical effort. The fixture application is uniform, and the product standards are consistent.
[0032] Furthermore, a plastic support leg 10 is provided on the lower surface of the first base plate 1, and bolts pass through the plastic support leg 10 to connect and fix it to the first base plate 1.
[0033] As mentioned above, the plastic support legs 10 provide cushioning and support, and also make it convenient for employees to insert their palms into the lower surface of the first base plate 1 to move it.
[0034] Furthermore, the left and right ends of the lower mold base 2 are respectively connected and fixed to the first base plate 1 through bolts; a third air hole 21 with vertical penetration is opened in the middle of the first limiting hole.
[0035] As described above, the lower mold base 2 is bolted together, allowing for disassembly and replacement of adhesive films 100 of different specifications. The third air hole 21 prevents gas from being squeezed out of the adhesive film 100 within the first limiting pit 20, thus preventing the formation of a vacuum and ensuring that the adhesive film 100 adheres to the end cap product 200.
[0036] Furthermore, a first limiting plate 30 is provided on the top of the two first guide posts 3; the first limiting plate 30 is also a metal plate; a first mounting hole 300 is provided at both ends of the first limiting plate 30; a second mounting hole 301 is provided in the middle of the first limiting plate 30.
[0037] The upper surface of the first guide post 3 has a protruding first threaded post 31; the first mounting holes 300 of the first limiting plate 30 are respectively fitted into the first threaded post 31 and screwed on with nuts to fix them; the limiting bolt 32 is inverted and passes through the second mounting hole 301 and screwed on with nuts to fix it; the limiting bolt 32 is located above the first moving plate 4.
[0038] As described above, in the specific assembly process, the first limiting plate 30 passes through the first threaded post 31 and is mounted on the first guide post 3, and is fixed with a nut; the limiting bolt 32 is placed according to the required height of the first moving plate 4, and is also fixed with a nut.
[0039] The limiting bolt 32 limits the height of the first moving plate 4 to prevent the upper mold base 5 from being pressed down too fast. If the impact force is too great, it will damage the end cover product 200 and the adhesive film 100.
[0040] Furthermore, it also includes a bushing 33; the bushing 33 is cylindrical, and the bottom outer surface of the bushing 33 protrudes from the first retaining ring 330; the bushing 33 is fitted between the first guide post 3 and the first moving plate 4, and the first retaining ring 330 is in contact with the first moving plate 4.
[0041] As described above, the bushing 33 is made of plastic material and is used for frictional movement between the first guide post 3 and the first moving plate 4. It can be replaced.
[0042] Furthermore, the first movable plate 4 is connected to a handle 40.
[0043] As described above, the handle 40 is welded to the first moving plate 4, enabling one-handed operation to move the first moving plate 4 up and down.
[0044] Furthermore, it also includes a sealing block 7; the sealing block 7 covers the first recess 52, and the countersunk bolt is screwed into the sealing block 7 to connect and fix it to the upper mold base 5; the sealing block 7 is a metal block, which covers and seals the first recess 52 of the upper mold base 5 to achieve a greater air extraction effect.
[0045] It also includes a first connecting post 70; the first connecting post 70 is cylindrical, and the surfaces at both ends are recessed to form threaded pits; the first connecting post 70 is clamped between the first moving plate 4 and the sealing block 7, and the bolt passes through the first moving plate 4 to be connected and fixed to the top of the first connecting post 70, and the countersunk bolt passes through the sealing block 7 to be connected and fixed to the bottom of the first connecting post 70.
[0046] As described above, the first connecting post 70 is clamped and fixed between the first moving plate 4 and the sealing block 7, serving as a connector that can support both the upper and lower parts.
