DETAILED DESCRIPTION

[0021] It is easy to understand that according to the technical solution of the present invention, without changing the essential spirit of the present invention, a person skilled in the art can propose a variety of interchangeable structural methods and implementation methods. Therefore, the following specific embodiments and drawings are only illustrative of the technical solution of the present invention and should not be regarded as the entire present invention or as a limitation or restriction of the technical solution of the present invention.

[0022] Figure 1 The overall structure of the left and right encapsulation mechanisms is schematically shown; Figure 2 The main structure of the right-side encapsulation mechanism is schematically shown; Figure 3 The diagram shows the rear view structure of the right side rubber encapsulation mechanism. Figure 1-3 As shown, it includes a left-side gluing mechanism and a right-side gluing mechanism that are relatively arranged. The aforementioned gluing mechanism includes a movable component 2 fixed to the front side of the workbench 1, and a movable plate 3 that can reciprocate in the transverse direction is provided on the movable component 2. A plurality of rollers 4, a cutting component and a feeding fixed component are fixedly provided on the movable plate 3, wherein the cutting component and the feeding fixed component are distributed on the left and right sides of the aforementioned plurality of rollers 4. A tensioning mechanism 7 is also fixedly provided on the movable plate 3. The tensioning mechanism 7 is fixedly provided between the rollers 4 and is used to adjust the tension of the tape;

[0023] The aforementioned tensioning mechanism 7 includes a bending piece, which is movably fixed on the movable plate 3 based on its bending part, and a roller 4 is movably fixed at the bending part and one end of the bending piece. At the other end of the bending piece, it is driven up and down by a first cylinder 72 fixed on the movable plate 3, thereby changing the position of the roller located at one end above the bending piece, thereby completing the adjustment of the tensioning force of the tape.

[0024] The following is a detailed description of the fixing method of the first cylinder 72 and the bending member. The first cylinder 72 is fixed to the side of the movable plate 3 facing the movable assembly 2, that is, the first cylinder 72 is fixed to the back side of the movable plate 3. The aforementioned plurality of rollers 4 and the bending member are fixedly provided on the front side of the movable plate 3. The telescopic rod of the aforementioned first cylinder 72 is movably fixed to one end of the bending member by a connecting rod 73. A limiting hole 74 is provided on the movable plate 3 that passes through the thickness direction of the movable plate 3. The limiting hole 74 is a long hole, and the connecting rod 73 can reciprocate in the aforementioned limiting hole 74. The telescopic movement of the first cylinder 72 drives one end of the bending member to change its longitudinal position. Because its bending part is movably fixed on the movable plate 3, the roller 4 located at the other end thereof can change its longitudinal and lateral positions accordingly. To facilitate the return of the bending part, an elastic component can be fixedly installed at the bending part. By using the connecting rod 73 to push one end of the bending part 71, when the connecting rod 73 returns, the return of the bending part can be regulated by the elastic component.

[0025] The cutting assembly is described in detail below. The cutting assembly is fixed to one side of the moving direction of the movable plate 3 and includes a second cylinder 51 fixed vertically and a cutter 52. The cutter 52 is fixed to the end of the telescopic rod of the second cylinder 51 and is used to cut the tape.

[0026] The present invention also includes a feeding assembly, which is fixedly arranged on one side of the moving direction of the movable plate 3, just like the aforementioned cutting assembly, and includes a locking mechanism and a movable clamping mechanism, while the aforementioned cutting assembly is fixedly arranged between the locking mechanism and the clamping mechanism. The aforementioned locking mechanism includes a stopper 811 fixed on the movable plate 3 and a movable block 812 coaxially arranged with the stopper 811, so that the movable block 812 can be located above or below the stopper 811. The movable block 812 is driven by a third cylinder 813 to move it closer to or further away from the aforementioned stopper 811, thereby completing the locking or loosening of the tape. The aforementioned third cylinder 813 is also fixedly arranged on the movable plate 3. The movable clamping mechanism includes a clamping cylinder 821 and a movable cylinder 822. The clamping cylinder 821 is fixed on the connecting block 823 facing the aforementioned block 811. The connecting block 823 is fixedly connected to the end of the telescopic rod of the movable cylinder 822. Under the action of the movable cylinder 822, the clamping cylinder 821 fixed on the aforementioned connecting block 823 can approach or move away from the block 811. During the feeding process, the locking mechanism first locks the end of the tape, and under the drive of the movable cylinder 822, the clamping cylinder 821 approaches the stop block 811, and the clamping cylinder 821 clamps the end of the tape. At this time, the third cylinder 813 drives the movable block 812 to move downward. After loosening the tape, the clamping cylinder 821, driven by the movable cylinder 822, pulls out the end of the tape to complete the feeding process; further, when the tape needs to be cut, after the clamping cylinder clamps the end of the tape, the movable block 812 moves upward under the action of the third cylinder 813, and is in close contact with the stop block 811 to complete the locking of the tape, and then the cutting mechanism completes the cutting of the tape.

[0027] It also includes a tensioning assembly 9, which is arranged between the aforementioned cutting assembly and the locking mechanism. The tensioning assembly 9 includes a fourth cylinder 91 fixed vertically on the movable plate 3, and a tensioning wheel is fixedly provided at the end of the movable rod of the fourth cylinder 91. The fourth cylinder 91 drives the tensioning wheel to move close to or away from the tape. When the tensioning wheel is in a position close to the tape, the tensioning wheel adjusts the tension of the tape to facilitate the cutting process or the encapsulation process.

[0028] It is worth noting that, in order to save space, the aforementioned second cylinder 51, third cylinder 813 and fourth cylinder 91 are fixedly arranged on the movable plate 3 in a parallel manner, and can drive the aforementioned block 811, tensioning wheel and cutter 52 to move upward in the form of a connecting rod. There is no need to arrange the aforementioned block 811, tensioning wheel and cutter 52 coaxially with the cylinder, which can save longitudinal space to a certain extent.

[0029] The movable component 2 includes a connecting plate 21 fixed to the front side of the workbench 1, a slide rail 22 is fixedly provided on the connecting plate 21 along the length direction of the connecting plate 21, and a slider matching the slide rail 22 is fixedly provided on the rear side of the movable plate 3. The movable plate 3 is movably fixed to the slide rail 22 by the slider. The movable plate 3 can be driven by a cylinder fixed on the workbench 1 to reciprocate along the length direction of the slide rail 22, thereby completing the adjustment of the lateral position of the movable plate 3 and facilitating the encapsulation process.

[0030] The aforementioned loading and fixing assembly is fixed to the side of the movable plate 3, facing away from the cutting assembly. The loading and fixing assembly includes a plate 61 and a limiting post 62 fixed between the plate 61. A limiting block 63 is mounted on the limiting post 62, and the limiting post 62 is used to fix the roll of adhesive tape. During the actual encapsulation process, the loading and fixing assembly 6 is used to fix the adhesive tape. The ends of the adhesive tape are sequentially wound around the roller 4. The roller 4 completes the tensioning and transfer of the adhesive tape, and the ends are placed in the locking mechanism. The movable clamping mechanism then clamps the ends of the adhesive tape to assist in the encapsulation process. After the encapsulation is completed, the tape is cut by the cutting mechanism. The entire process is completely automatic and does not require additional human assistance. In addition, by setting up a completely symmetrical rubber wrapping mechanism on the left and right, the rubber wrapping process of the casing can be carried out multiple times, and the continuous rubber wrapping process can be guaranteed. That is, when the tape on one side is used up, the rubber wrapping mechanism on the other side can be used in time to continue the rubber wrapping process. At this time, the used tape can be replenished, avoiding the stop of the production process due to the need to replenish materials, and improving production efficiency.

[0031] The technical scope of the present invention is not limited to the contents described above. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical concept of the present invention, and these deformations and modifications should all fall within the scope of protection of the present invention.
