[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Please see attached picture Figures 1 to 3 As shown, the adhesive tape assembly structure in the embodiment of the utility model includes a base plate 1, and also includes: an adhesive tape mounting wheel 2, which is rotatably arranged on the upper end of one side of the base plate 1, and the outer end of the adhesive tape mounting wheel 2 is sleeved with an adhesive tape roll 3. Since the adhesive tape mounting wheel 2 is rotatably connected, when the adhesive tape on the adhesive tape roll 3 is pulled, the adhesive tape roll 3 can drive the adhesive tape mounting wheel 2 to rotate, thereby facilitating the pulling out of the adhesive tape.

[0031] The counting component 4 includes a counting wheel 401 and a counting optical fiber sensor 402. The outer periphery of the counting wheel 401 passes through the detection area of ​​the counting optical fiber sensor 402. The counting wheel 401 is sleeved on the rear end of the adhesive tape installation wheel 2. The counting optical fiber sensor 402 is fixed to the bottom plate 1. Through the setting of the counting component 4, the number of adhesive tapes pasted can be counted and whether the adhesive tape is cut can be detected at the same time. Specifically, the counting wheel 401 rotates synchronously with the adhesive tape installation wheel 2. Through the detection of the counting optical fiber sensor 402, when the counting wheel 401 rotates once, the counting optical fiber sensor 402 feeds back once for counting, and also indicates that the adhesive tape is pulled out and one adhesive tape installation is completed. If the counting optical fiber sensor 402 does not feed back, it means that the adhesive tape is not pulled out and the adhesive tape is not installed. In addition, after the adhesive tape cutting knife 5 moves once, if the counting optical fiber sensor 402 still detects the counting wheel 401, it means that the adhesive tape has not been cut and manual intervention is required. On the contrary, if it is detected that the counting wheel 401 stops rotating, it means that the adhesive tape is successfully cut and continues to work.

[0032] The upper end of the pressing swing arm 6 is rotatably connected to the bottom plate 1 , and the lower end of the pressing swing arm 6 is rotatably connected to the pressing wheel 11 . The pressing swing arm 6 can be rotated and pressed downward, and the end of the adhesive tape is fitted to the PCB through the pressing wheel 11 .

[0033] The rolling cylinder 8 is fixed on the side of the lower end of the base plate 1 away from the lower pressure swing arm 6. A wheel frame 9 is fixed at the lower end of the slide of the rolling cylinder 8, and a tape cutting knife 5 is fixed at the upper end. One end of the wheel frame 9 is rotatably connected to a rolling wheel 10. The rolling wheel 10 is close to the lower pressure wheel 11. After the tape is attached to the PCB, the tape cutting knife 5 cuts the tape, and then the rolling cylinder 8 is actuated to cause the rolling wheel 10 to lower and roll the tape, so that the tape is tightly attached to the PCB.

[0034] As an implementation of the present utility model, please refer to the attached drawings. Figure 3 As shown, the adhesive tape installation wheel 2 includes a wheel body 201, and a plurality of tensioning blocks 202 are evenly fixed on the outer end of the wheel body 201. The tensioning blocks 202 are tightly abutted against the inner circle of the adhesive tape roll 3. The setting of the tensioning blocks 202 enables the adhesive tape roll 3 to be stably connected to the wheel body 201, wherein the tensioning blocks 202 are made of elastic material and have an oblique angle at the end to facilitate the smooth assembly of the adhesive tape roll 3.

[0035] In addition, in order to adjust the damping of the tape installation wheel 2, a connecting column 203 is fixed at the center of the outer end of the wheel body 201, the outer end of the connecting column 203 is threadedly sleeved with an adjusting handle 205, the inner end is sleeved with a friction plate 204, and the middle part of the connecting column 203 is sleeved with a spring 206, the upper and lower ends of the spring 206 are respectively abutted against the adjusting handle 205 and the friction plate 204. Since the adjusting handle 205 is threadedly sleeved with the connecting column 203, when the adjusting handle 205 is tightened, the spring 206 is compressed, and the friction force between the friction plate 204 and the wheel body 201 is increased, thereby improving the damping. Similarly, when the adjusting handle 205 is loosened, the friction force between the friction plate 204 and the wheel body 201 is reduced, thereby reducing the damping, which is convenient for adapting to different usage requirements.

[0036] As an implementation method of the utility model, please refer to the attached drawings Figure 1 to Figure 2 As shown, the upper side of the front end surface of the lower pressure swing arm 6 is rotatably connected to the guide shaft 14, and the lower side near the lower pressure wheel 11 is rotatably connected to the guide shaft 2 16. A detection optical fiber sensor 15 is provided on the lower pressure swing arm 6 near the guide shaft 14. The setting of the guide shaft 14 and the guide shaft 2 16 facilitates the tensioning of the adhesive tape and the changing direction of the adhesive tape. The detection optical fiber sensor 15 is used to detect whether there is adhesive tape passing through. If there is no feedback, it means that the adhesive tape is exhausted and needs to be replaced.

[0037] It should be noted that the adhesive tape on the adhesive tape roll 3 is first pulled out from the side close to the guide shaft 14, bypasses the right side of the guide shaft 14, then bypasses the lower side of the guide shaft 2 16, and finally passes through the lower side of the lower pressure wheel 11, wherein the adhesive tape contacts the guide shaft 14, the guide shaft 2 16, and the lower pressure wheel 11 through the non-adhesive surface.

[0038] As an implementation method of the utility model, please refer to the attached drawings Figure 1 to Figure 2 As shown, a pressing cylinder 12 is fixed at the middle of the front end surface of the base plate 1, and the protruding end of the pressing cylinder 12 is hingedly connected to the pressing swing arm 6. A clamping assembly 7 is arranged on the lower side of the pressing swing arm 6. The pressing cylinder 12 drives the pressing swing arm 6 to be pressed downward, and the clamping assembly 7 is used to clamp the adhesive tape and the lower pressing wheel 11 after cutting to prevent the adhesive tape from falling out.

[0039] Specifically, the clamping assembly 7 includes a clamping cylinder 701 fixed to the lower pressure swing arm 6, and a clamping block 702 is fixed to the protruding end of the clamping cylinder 701. The clamping block 702 is L-shaped, and the end is close to the lower pressure wheel 11. The clamping cylinder 701 drives the clamping block 702 to approach the lower pressure wheel 11, so that the adhesive tape is clamped between the lower pressure wheel 11 and the end of the clamping block 702. When the adhesive tape is pasted, the lower pressure wheel 11 attaches the adhesive surface of the tape to the PCB. At this time, the clamping cylinder 701 drives the clamping block 702 to retreat, and then as the base plate 1 moves, the adhesive tape can be pulled out smoothly.

[0040] As an implementation method of the utility model, please refer to the attached drawings Figure 2 and Figure 4 As shown, the adhesive tape cutting knife 5 includes a cutting cylinder 501 fixed to the slide of the rolling cylinder 8, a cutting seat 502 is fixed to the protruding end of the cutting cylinder 501, and a blade 503 is arranged at the lower end of the blade seat 502. The cutting cylinder 501 drives the blade 503 to move, thereby cutting the adhesive tape.

[0041] In addition, the knife seat 502 is fixed with a pressing plate 504 by screws, the blade 503 is clamped between the knife seat 502 and the pressing plate 504, a scale 505 is provided on the outer side of the knife seat 502, and the blade 503 is clamped between the knife seat 502 and the pressing plate 504, so that the position of the blade 503 can be adjusted, thereby adjusting the distance between the blade 503 and the adhesive tape, so as to adapt to different usage requirements.

[0042] As an implementation method of the utility model, please refer to the attached drawings Figure 1 As shown, a rotating shaft seat 13 is fixed to the upper end of the bottom plate 1 of the adhesive tape cutting knife 5 , and the rotating shaft seat 13 is used to connect with an external moving mechanism, thereby driving the bottom plate 1 to move.

[0043] Working principle: the bottom plate 1 is connected to the external moving mechanism through the rotating shaft seat 13. When pasting the adhesive tape, the end of the adhesive tape is clamped between the lower pressure wheel 11 and the clamping block 702 and extends a certain distance. The lower pressure cylinder 12 is actuated to drive the lower pressure wheel 11 to fit the end of the adhesive tape on the PCB board. At the same time, the clamping block 702 is released, the bottom plate 1 moves, and the adhesive tape is pulled out. When the adhesive tape is pulled out, the rolling cylinder 8 is actuated, and the rolling wheel 10 is lowered to roll the adhesive tape synchronously to ensure that the adhesive tape is tightly attached. After the adhesive tape is pulled out to a set length, the adhesive tape cutting knife 5 is actuated once to cut the adhesive tape, the clamping block 702 is clamped, and after the rolling wheel 10 rolls the remaining adhesive tape, the rolling cylinder 8 is reset to complete one adhesive tape pasting. Among them, through the setting of the counting component 4, the number of pasted adhesive tapes can be counted, and at the same time, it can be detected whether the adhesive tape is cut.

[0044] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
