[0002] After punching, the automotive terminals need to be wound onto an H-shaped paper tray. The sides of the paper tray need to be sealed with tape. The tape is pasted in a U-shape, usually at three or four points, that is, the paper tray is sealed with tape every 120° or 90° to prevent the wound automotive terminals from loosening during subsequent transportation. The existing paper trays are sealed manually, with low pasting efficiency, and it is difficult to ensure that the lengths pasted on the two sides of the paper tray are consistent. Summary of the invention

[0003] The invention aims to solve the technical problems that the existing U-shaped adhesive tape has low efficiency and is difficult to ensure the length of the adhesive tapes on both sides.

[0004] The technical solution adopted by the present invention to solve its technical problem is:

[0005] A U-shaped adhesive tape pasting device comprises a fixed vertical plate, which is arranged vertically in the left and right directions, and is fixedly connected (directly or indirectly) to an air shaft (the air shaft is used to wind the adhesive tape); two pressure rollers arranged opposite to each other on the left and right sides are rotatably installed on the vertical plate through a mounting frame (the rollers can rotate freely), and the axes of the pressure rollers are arranged vertically, and a gap is left between the two pressure rollers for accommodating workpieces; and a cutting mechanism is also included, which is located outside the gap (i.e., on the left side of the left pressure roller or on the right side of the right pressure roller), and the cutting mechanism comprises a blade and a linear drive pair driving the blade away from or close to the vertical plate, and the linear drive pair is fixedly connected (directly or indirectly) to the vertical plate. The invention relates to a vertical plate; it also includes a first clamping jaw mechanism and a second clamping jaw mechanism for clamping the tape, the clamping jaws of the first clamping jaw mechanism and the second clamping jaw mechanism are arranged opposite to each other on the left and right sides and are located in the direction of the pressure roller away from the vertical plate, the first clamping jaw mechanism is fixedly connected (directly or indirectly) to the vertical plate and is located on the outside of the cutter mechanism, and the second clamping jaw mechanism and the cutter mechanism are located on the same side of the first clamping jaw mechanism; it also includes a first cylinder and a second cylinder, the first cylinder and the second cylinder are both arranged in the left and right directions, the cylinder body of the first cylinder is fixed to the vertical plate, the movable part is fixedly connected to the cylinder body of the second cylinder, and the movable part of the second cylinder is fixedly connected to the second clamping jaw mechanism.

[0006] The beneficial effects of the present invention are:

[0007] 1) The U-shaped adhesive tape pasting device of the present invention is provided with an air shaft, a pressure roller, a cutter mechanism, a clamping claw mechanism, etc., which cooperate with each other to realize the mechanization of U-shaped adhesive tape pasting, which greatly improves the pasting efficiency and reduces the labor cost compared with the existing manual work; and in combination with the relevant software design, the device can be used in an automated production line, which can better meet the needs of industrial automation;

[0008] 2) In the U-shaped adhesive tape pasting device of the present invention, the second clamping mechanism is driven by a double cylinder method, and the two cylinders cooperate to stretch the adhesive tape.

DETAILED DESCRIPTION

[0014] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0015] Reference Figure 1The U-shaped adhesive tape pasting device of the present invention comprises a fixed vertical plate 1, which is arranged vertically in the left and right directions. The vertical plate 1 is fixedly connected with an inflatable shaft 2, which is a commonly used structure in the art. In specific implementation, a friction damping structure can be configured to tension the adhesive tape when the adhesive tape is stretched; two pressure rollers 4 arranged opposite to each other on the left and right are rotatably installed on the vertical plate 1 through a mounting frame 3, and the axis of the pressure roller 4 is arranged vertically. The mounting frame 3 can adopt an ordinary connection structure, and a gap 5 is left between the two pressure rollers 4 to accommodate the workpiece; it also includes a cutting mechanism located outside the gap 5, the cutting mechanism includes a blade 6 and a linear driving pair 7 driving the blade 6 away from or close to the vertical plate 1, the linear driving pair 7 is fixedly connected to the vertical plate 1, and the linear driving pair 7 can adopt a cylinder, a motor screw pair, a motor synchronous belt and the like. Here, a cylinder is preferably used for driving, a On the one hand, it can better adapt to the space requirements of the entire equipment, and on the other hand, the cost is also low; it also includes a first clamping jaw mechanism 8 and a second clamping jaw mechanism 9 for clamping the tape. The clamping jaw mechanism is a mature structure in this field, and preferably uses pneumatic fingers with simple structure and low cost; the clamping jaws of the first clamping jaw mechanism 8 and the second clamping jaw mechanism 9 are arranged opposite to each other on the left and right and are located in the direction away from the vertical plate 1 of the pressure roller 4, the first clamping jaw mechanism 8 is fixedly connected to the vertical plate 1 and is located on the outside of the cutter mechanism, and the second clamping jaw mechanism 9 and the cutter mechanism are located on the same side of the first clamping jaw mechanism 8; it also includes a first cylinder 10 and a second cylinder 11, the first cylinder 10 and the second cylinder 11 are both arranged in the left and right direction, the cylinder body of the first cylinder 10 is fixed on the vertical plate 1, the movable part is fixedly connected to the cylinder body of the second cylinder 11, and the movable part of the second cylinder 11 is fixedly connected to the second clamping jaw mechanism 9.

[0016] When working, it is divided into the following structural steps:

[0017] S1, first wrap the tape around the inflatable shaft 2, and clamp the end of the tape in the clamping claw of the first clamping claw mechanism 8;

[0018] S2, the first cylinder 10 is controlled to move, and the second cylinder 11 is moved to a state where the movable part is located closest to the first clamping mechanism 8, so that the second clamping mechanism 9 is close to the first clamping mechanism 8 until the clamping jaws of the second clamping mechanism 9 clamp the end of the tape, and then the clamping jaws of the first clamping mechanism 8 are released, and the first cylinder 10 and the second cylinder 11 move in opposite directions, and the second clamping mechanism 9 moves away from the first clamping mechanism 8, so that the tape is stretched to its longest length;

[0019] S3, then align the position on the side of the workpiece to be pasted with the gap 5 and make it contact with the tape, then start the second cylinder 11 to move it in the direction close to the first clamping mechanism 8, and at the same time press the workpiece in the direction close to the vertical plate 1, the tape is pasted on the surface of the workpiece in a U shape and the length of the tape pasted on the surface gradually increases;

[0020] S4, when the second cylinder 11 moves to the extreme position, the first clamping mechanism 8 clamps the tape, and then the second clamping mechanism 9 releases the tape, and at the same time, the blade 6 moves away from the vertical plate 1 under the action of the linear drive pair 7 until the tape is cut;

[0021] S5, the workpiece continues to move toward the vertical plate 1 until the pressure wheel presses the two ends of the tape tightly against the surface of the workpiece, and then the workpiece is taken out;

[0022] S6. Repeat S2-S5 to process the next workpiece.

[0023] There are actually two ways to connect the first cylinder 10 and the second cylinder 11: one is that the second cylinder 11 is extended in the direction away from the first clamping mechanism 8. In this way, in step S2, the second cylinder 11 should be retracted first and then extended, and then retracted in step S3; the second is that the second cylinder 11 is extended in the direction close to the first clamping mechanism 8. In this way, in step S2, the second cylinder 11 should be extended first and then retracted, and then extended in step S3. Both methods are acceptable, but the first method is preferred because the first method is more convenient for structural space arrangement.

[0024] Here, the consistency of the length of the tape on the two surfaces of the workpiece is ensured as follows: in combination with the orientation of the accompanying drawings, it is only necessary to set the stroke of the second cylinder 11 so that the second cylinder 11 moves to the point in step S3 where the clamping position of the second clamping mechanism 9 and the cutting position of the cutting mechanism are symmetrical about the gap 5 and stops. Because one end of the tape is clamped in the clamping jaws of the second clamping mechanism 9 and the other end is formed by cutting with the cutter, now the clamping jaws of the second clamping mechanism 9 are symmetrical with the cutting position, that is, the length of the tape exposed in the gap 5 is consistent, and the gap 5 is U-shaped, and the length of the tape on both sides is also consistent, thereby ensuring that the length of the tape on the two surfaces of the workpiece is consistent.

[0025] Furthermore, the inflatable shaft 2 is fixed to the back of the vertical plate 1, and a first mounting plate 12 is vertically fixed to the front of the vertical plate 1. At least two redirecting rollers 13 are rotatably mounted on the outer surface of the first mounting plate 12, and the redirecting rollers 13 and the pressure rollers 4 are in the same horizontal plane. This structure can reduce the occupied space and has strong structural stability. In specific implementation, the number and position of the redirecting rollers 13 should be easy to design by those skilled in the art. Preferably, one of the redirecting rollers 13 can be arranged on the right side of the first clamping mechanism 8, so that the first clamping mechanism 8 will not be subjected to pulling force when clamping the tape, which is more conducive to the stability of the structure.

[0026] Preferably, the first cylinder 10 is a rodless cylinder, and the second cylinder 11 is a slide cylinder. If an ordinary cylinder is used, the structural installation and connection is not very convenient. The use of a rodless cylinder and a slide cylinder greatly simplifies the connection structure between the two cylinders, and the structural stability is stronger. Further, the slide cylinder extends in a direction away from the first clamping jaw mechanism 8.

[0027] Furthermore, a second mounting plate 14 is vertically fixed to the front of the vertical plate 1, and the linear drive pair 7 and the first clamping mechanism 8 are both fixed to the second mounting plate 14. This is a preferred connection structure, with smoother structural connection, reasonable spatial arrangement, and stronger structural stability. In other embodiments, the linear drive pair 7 and the first clamping mechanism 8 can be fixed to the vertical plate 1 directly or indirectly through other components.

[0028] Furthermore, the distance between the two pressure rollers 4 is adjustable, and the distance between the pressure rollers 4 and the vertical plate 1 is adjustable. The adjustment of the above two distances is a common design in this field, and is usually achieved by using structures such as strip holes. Specifically, the distance between the pressure roller 4 and the vertical plate 1 can be adjusted by adjusting the position of the pressure roller 4 on the mounting frame 3; the distance between the two pressure rollers 4 can be adjusted by adjusting the positions of the two mounting frames 3 on the vertical plate 1. The position adjustment can be achieved by using strip holes in combination with bolts or other common structures. The distance between the two pressure rollers 4 is adjustable, so that the device can be used to attach workpieces of different thicknesses; the distance between the pressure roller 4 and the vertical plate 1 is adjustable, so that the device can meet the requirements for different adhesive lengths of the tape.
