[0061] In this embodiment, the first clamping roller 64 and the second clamping roller 66 can also be rotatably connected to the second frame 62, so that the friction force of the first clamping roller 64 and the second clamping roller 66 on the tape can be reduced, making it easier for the tape clamp to grab; when this solution is used in combination with the second hollow groove 622, the two ends of the first clamping roller 64 are respectively rotatably connected to the corresponding second hollow groove 622.

[0066] The workpiece of the device is not limited to the audio speaker bracket. The top surface of the first frame 32 of the device needs to be adapted to the workpiece, and the positioning mechanism can be designed separately according to the workpiece.

[0067] like Figure 2 , 4 As shown, preferably, it also includes a secondary pasting mechanism 5, the secondary pasting mechanism 5 includes a fourth bracket 52, the fourth bracket 52 is provided with a fourth driving device 54, the fourth driving device 54 is provided with a tape secondary bending mechanism on the side facing the workbench 3, and the fourth driving device 54 is used to drive the tape secondary bending mechanism to stick the tape to the bottom surface of the workpiece.

[0070] Specifically, the workpiece is located between the first tape secondary bending portion 56 and the second tape secondary bending portion 58; if the thickness of the workpiece is small, when the tape is only pasted to the front and side of the workpiece, the tape pasted to the workpiece is easy to fall off, such as: an audio speaker bracket, at this time, the tape must also be pasted to the bottom surface of the workpiece to reduce the risk of the tape falling off; the length of the tape to be pasted can be controlled by controlling the setting position of the shearing device 9 and the third drive device 48, so as to ensure that the tape length is still sufficient after the primary pasting mechanism 2 pastes the tape to the front and side of the workpiece, so that the secondary pasting mechanism 5 can be used to paste the tape to the bottom surface of the workpiece.

[0071] The working principle of this scheme is as follows. After the primary pasting mechanism 2 of this device pastes the tape to the front and side of the workpiece, the piston rod of the sixth drive device 102 retracts. After retracting into place, the fourth drive device 54 controls the first tape secondary bending portion 56 and the second tape secondary bending portion 58 to move toward each other, so that one side of the workpiece along the second direction is located in the first bending groove 562, and the other side of the workpiece along the second direction is located in the second bending groove 582. In this process, the side wall of the first bending groove 562 sticks the tape on one side of the workpiece to the bottom surface of the workpiece, and the side wall of the second bending groove 582 sticks the tape on the other side of the workpiece to the bottom surface of the workpiece.

[0072] The fourth driving device 54 can also select two cylinders to replace the first pneumatic finger. The first tape secondary bending part 56 is connected to one of the cylinders, and the second tape secondary bending part 58 is connected to the other cylinder. In this way, the tape can also be attached to the bottom surface of the workpiece.

[0074] Specifically, it also includes a third bracket 44, the third bracket 44 includes a first body and a second body connected to the first body, the first body is connected to the piston rod of the second drive device 43, the third drive device 48 is fixedly arranged on the side of the first body away from the second drive device 43, the second body extends to the side away from the third drive device 48, and the length direction of the second body is parallel to the second direction, a first accommodating space is formed between the first body and the second body, and the second drive device 43 is accommodated in the first accommodating space; a limiting protrusion 442 is also protruding from the side of the second body away from the second drive device 43, and a push rod 264 is also arranged on the first bracket 14, the axial direction of the push rod 264 is parallel to the second direction, the setting position of the push rod 264 is adapted to the setting position of the limiting protrusion 442, and the direction of the third drive device 48 pointing to the second drive device 43 is the same as the direction of the limiting protrusion 442 pointing to the push rod 264. With such arrangement, when the piston rod of the second drive device 43 retracts, that is, the piston rod moves in the direction of the third drive device 48 pointing to the second drive device 43, the piston rod will drive the third bracket 44 and the third drive device 48 to move in this direction, and the push rod 264 stops moving when it abuts against the limiting protrusion 442; the cooperation between the limiting protrusion 442 and the push rod 264 can limit the third drive device 48 in the direction of the third drive device 48 pointing to the second drive device 43, thereby controlling the length of the tape grasped by the tape clamp.

[0075] More preferably, the push rod 264 and the first bracket 14 are connected by threads, so that the length of the tape grasped by the tape clamp can be easily controlled.

[0076] More preferably, it also includes a second bracket 41, the second bracket 41 includes a third body and a fourth body connected to the third body, the third body is vertically arranged, the fourth body is horizontally arranged, and the fourth body extends to the side away from the second drive device 43, the third body is connected to the first body, the third drive device 48 is connected to the side of the third body away from the first body, the third body and the fourth body form a second accommodating space, the third drive device 48 is accommodated in the second accommodating space, and the fourth body is located above the third drive device 48; the top surface of the fourth body is also fixedly connected to a guide member 47, the bottom surface of the guide member 47 is provided with a guide groove, and the first bracket 14 is also fixedly provided with a guide rail 42, the length direction of the guide rail 42 is parallel to the second direction, and the guide groove is slidably connected to the guide rail 42. This solution enables the gravity of the third drive device 48 to act on the first bracket 14 through the cooperation of the guide member 47 and the guide rail 42, thereby reducing the risk of deformation of the piston rod of the second drive device 43; if this solution is not adopted, the gravity of the third drive device 48 directly acts on the piston rod of the second drive device 43, and long-term use may cause the piston rod of the second drive device 43 to deform. Therefore, the piston rod of the second drive device 43 will extend obliquely downward, which may cause the tape clamp to be unable to grab the tape.

[0077] In the above scheme, the first driving device 22 of the one-time pasting mechanism 2 is further connected to the top surface of the fourth body, and an avoidance hole of the fixing part 24 is set at the corresponding position of the fourth body, so that the space of the entire device in the height direction can be compressed. If the one-time pasting mechanism 2 is directly set on the base 1 through the bracket, in order to avoid interference with the third driving device 48 and the tape clamp, the one-time pasting mechanism 2 needs to be erected at a higher position, which will waste space on the one hand and cause instability of the equipment on the other hand.

[0078] In addition, the third driving device 48 can also select two cylinders to replace the second pneumatic finger. The first tape clamp 45 is connected to one of the cylinders, and the second tape clamp 46 is connected to the other cylinder, so that the tape can also be grasped.

[0079] like Figure 7 As shown, preferably, the bottom of the primary bending portion 28 of the adhesive tape is further connected with a pressing portion 282 , and the pressing portion 282 is in an arc shape convex toward the pressing block 26 , and the pressing portion 282 is in contact with the pressing block 26 .

[0080] Specifically, the first bending portion 28 of the adhesive tape is in the form of a sheet. If the clamping portion 282 is not provided, the first bending portion 28 of the adhesive tape may damage the adhesive tape. After the clamping portion 282 is provided, since the clamping portion 282 is in the form of an arc, the clamping portion 282 will not cause the problem of damage to the adhesive tape. More preferably, the clamping portion 282 is an elastic member. When the clamping portion 282 is an elastic member, the working steps are as follows: the piston rod of the first driving device 22 is pushed out, the fixing member 24 moves downward, and the pressing block 26 moves downward accordingly. After the pressing block 26 sticks the adhesive tape to the top surface of the workpiece, the piston of the first driving device 22 should continue to be pushed out, the first elastic member 29 is compressed, and the clamping portion 282 is out of contact with the pressing block 26. Then, the clamping portion 282 is in close contact with the side of the workpiece due to its own elasticity, so that the adhesive tape can be attached more firmly, and the air between the adhesive tape and the side of the workpiece can be discharged, reducing the risk of the adhesive tape falling.

[0081] Preferably, the number of workbenches 3 is two, the number of sixth drive devices 102 and the number of secondary pasting mechanisms 5 are both compatible with the number of workbenches 3, the workbenches 3 are respectively located on both sides of the primary pasting mechanism 2 along the first direction, the sixth drive devices 102 are respectively located at both ends of the first guide portion 12, and the secondary pasting mechanisms 5 are respectively located at both ends of the first guide portion 12.

[0082] Specifically, two workbenches 3 can constitute a double workstation, which can improve processing efficiency.

[0083] The working steps of the device of the present invention are as follows:

[0084] S10, manually threading the tape to the first tape guide mechanism 6, and passing the tape through the first tape guide mechanism 6; the piston rod of the second drive device 43 is pushed out, so that the tape clamp moves to the tape, and the fourth drive device 54 drives the second tape clamp 46 and the first tape clamp 45 to move toward each other, so as to clamp the tape, and then the piston rod of the second drive device 43 is retracted; wherein, manual threading is required only when a new tape is used;

[0085] S20, the piston rod of the sixth driving device 102 extends, so that the workbench 3 with the workpiece on the top slides to the bottom of the primary pasting mechanism 2, and the adhesive tape is located above the workpiece;

[0086] S30, the piston rod of the first driving device 22 is pushed out, so that the pressing block 26 sticks the tape to the top surface of the workpiece, and then the shearing device 9 cuts the tape between the worktable 3 and the first tape guide mechanism 6, and at the same time the tape clamp releases the tape, and then the tape primary bending portion 28 sticks the tape to the side of the workpiece;

[0087] S40, the piston rod of the sixth driving device 102 is retracted, and the fourth driving device 54 drives the first tape secondary bending portion 56 and the second tape secondary bending portion 58 to move toward each other, so that the tape is attached to the bottom of the workpiece;

[0088] When the number of the workbench 3, the secondary pasting mechanism 5 and the sixth driving device 102 is two, there is a step S35 between S30 and S40, and S35 and S40 are performed simultaneously;

[0089] S35, repeat S10, the piston rod of another sixth driving device 102 is extended, and another workbench 3 with a workpiece on the top slides to the bottom of the primary pasting mechanism 2, and the tape is now located above the workpiece; repeat S30, the piston rod of another sixth driving device 102 is retracted, and the fourth driving device 54 drives the first tape secondary bending portion 56 and the second tape secondary bending portion 58 to move toward each other, so that the tape is pasted to the bottom of the workpiece.

[0090] Repeat the above steps.
