Description

Technical Field

[0001] The utility model relates to the technical field of carrier tape edge cutting, and more specifically to a carrier tape edge cutting device. Background Art

[0002] A carrier tape refers to a strip product used in the field of electronic packaging. It has a specific thickness and has holes (also called pockets) for holding electronic components and positioning holes for indexing and positioning evenly distributed along its length. During the production process of the carrier tape, its sides need to be trimmed and removed to a certain extent. At this time, a carrier tape trimming device is required.

[0003] The existing carrier tape trimming device is usually composed of two parts: a traction structure and a cutting structure. Its overall structure is relatively complex, which easily leads to an increase in its production cost and is not conducive to its popularization and use. In view of this, we propose a carrier tape trimming device. Utility Model Content

[0004] The utility model aims to overcome the deficiencies of the prior art, meet practical needs, and provide a carrier tape trimming device to solve the technical problems that the current carrier tape trimming device has a complex structure, high cost, and is not conducive to popularization and use.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: a carrier tape trimming device, comprising a concave frame, a symmetrical driven traction cutting structure is arranged inside the concave frame for front and back rotation, an active traction cutting structure symmetrical to the driven traction cutting structure is arranged inside the concave frame for front and back rotation, a driving structure is arranged on both sides of the concave frame, the driven traction cutting structure comprises a driven traction roller, matching cutting grooves are opened on both sides of the surface of the driven traction roller, the active traction cutting structure comprises an active traction roller, and knife discs symmetrical to the matching cutting grooves are arranged on both sides of the surface of the active traction roller;

[0006] The surface of the driven traction roller is located between the two groups of matching cutting grooves and is provided with a plurality of groups of notches at equal intervals, and the spacing of the notches matches the spacing of the holes on the carrier belt, and the size of the notches matches the size of the holes on the carrier belt. The surface of the active traction roller is located between the two groups of knife discs and is provided with a plurality of groups of protrusions at equal intervals, and the spacing of the protrusions matches the spacing of the holes on the carrier belt, and the size of the protrusions matches the size of the holes on the carrier belt.

[0007] The utility model cooperates with the designed driven traction cutting structure and the active traction cutting structure. The active traction roller on the active traction cutting structure cooperates with the driven traction roller on the driven traction cutting structure to clamp the carrier belt. Then the active traction roller rotates, which drives the carrier belt to move, thereby realizing the traction effect on the carrier belt. In the process of traction of the carrier belt, the knife disc on the active traction cutting structure cooperates with the matching cutting groove on the driven traction cutting structure to directly complete the side cutting of the carrier belt, thereby realizing the edge cutting processing of the carrier belt. Therefore, the driven traction cutting structure and the active traction cutting structure realize the traction and cutting of the carrier belt. The edges are integrated, the structure is simple, and the production cost can be reduced. When the driven traction roller and the active traction roller cooperate to pull the carrier tape, during the transmission of the carrier tape, the holes thereon will reciprocate through the slots on the driven traction roller, and then the raised blocks on the active traction roller will reciprocate through the holes of the carrier tape. On the one hand, it can have a limiting effect on the transmission of the carrier tape to avoid its deviation, thereby ensuring the accuracy of the cutting edge of the carrier tape by the knife disc and the coordinated cutting grooves; on the other hand, it can avoid the situation in which the holes of the carrier tape are squeezed and deformed during the traction of the carrier tape by the active traction roller and the driven traction roller, thereby affecting the subsequent use of the carrier tape.

[0008] Preferably, first connecting shafts are arranged at the centers of both sides of the driven traction roller, and the first connecting shafts are rotatably connected to the inner wall of the concave frame through bearings.

[0009] Preferably, a second connecting shaft is arranged in the center of both sides of the active traction roller, the driving structure includes an electric hydraulic push rod and a connecting plate, the connecting plate is arranged at the piston end of the electric hydraulic push rod, and one end of the second connecting shaft is rotatably connected to the connecting plate through a bearing.

[0010] Preferably, a group of the connecting plates are provided with motors at both ends of one side facing away from the concave frame, and the rotating shafts at the output ends of the motors are connected to the corresponding second connecting shafts.

[0011] Preferably, a mounting plate is arranged at the center of the top of both sides of the concave frame, and the cylinder body of the electric hydraulic push rod is arranged on the mounting plate.

[0012] Preferably, rectangular through holes are formed on both sides of the concave frame, and the second connecting shaft passes through the rectangular through holes.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The utility model cooperates the designed driven traction and cutting structure with the active traction and cutting structure. The active traction roller on the active traction and cutting structure cooperates with the driven traction roller on the driven traction and cutting structure to clamp the carrier tape. Then the active traction roller rotates, which will drive the carrier tape to move, thereby achieving the traction effect on the carrier tape. In the process of traction of the carrier tape, the knife disc on the active traction and cutting structure cooperates with the matching cutting groove on the driven traction and cutting structure to directly complete the side cutting of the carrier tape, thereby achieving the trimming of the carrier tape. Therefore, the driven traction and cutting structure and the active traction and cutting structure realize the integration of traction and trimming of the carrier tape, have a simple structure, and can reduce the production cost, thereby solving the technical problems that the current carrier tape trimming device has a complex structure, high cost, and is not conducive to popularization and use. Therefore, the utility model has the advantages of simple structure and low production cost.

[0015] 2. The utility model also provides a notch on the driven traction roller and a raised block on the active traction roller. Therefore, when the driven traction roller and the active traction roller cooperate to pull the carrier tape, during the transmission of the carrier tape, the holes thereon will reciprocate through the notch on the driven traction roller, and then the raised block on the active traction roller will reciprocate through the holes of the carrier tape. On the one hand, it can have a limiting effect on the transmission of the carrier tape to avoid its deviation and ensure the accuracy of the cutting edge of the carrier tape by the knife disc and the cooperating cutting groove. On the other hand, it can avoid the situation in which the holes of the carrier tape are squeezed and deformed during the traction of the carrier tape by the active traction roller and the driven traction roller, thereby affecting the subsequent use of the carrier tape.

The active traction and cutting structure 3 is lowered, so that the active traction roller 301 cooperates with the driven traction roller 201 to clamp the carrier tape, and then the active traction and cutting structure 3 is driven to rotate through the driving structure 4. The active traction roller 301 on the active traction and cutting structure 3 rotates, and cooperates with the driven traction roller 201 to drive the carrier tape to move, so as to achieve the traction effect on the carrier tape, and in the process of traction of the carrier tape, the knife disc 302 on the active traction roller 301 cooperates with the matching cutting groove 202 on the driven traction roller 201 to directly complete the side cutting of the carrier tape, so as to achieve the trimming of the carrier tape. Therefore, the driven traction and cutting structure 2 and the active traction and cutting structure 3 realize the integration of traction and trimming of the carrier tape, and the structure is simple, and the production cost can be reduced.

[0024] Specifically, first connecting shafts 204 are arranged in the center of both sides of the driven traction roller 201 , and the first connecting shafts 204 are rotatably connected to the inner wall of the concave frame 1 through bearings, and the driven traction roller 201 is rotatably installed through the first connecting shafts 204 .

[0025] Furthermore, a second connecting shaft 304 is arranged in the center of both sides of the active traction roller 301, and the driving structure 4 includes an electric hydraulic push rod 401 and a connecting plate 402. The connecting plate 402 is arranged at the piston end of the electric hydraulic push rod 401, and one end of the second connecting shaft 304 is rotatably connected to the connecting plate 402 through a bearing; a group of connecting plates 402 are arranged with motors 403 at both ends of one side facing away from the concave frame 1, and the rotating shaft of the output end of the motor 403 is connected to the corresponding second connecting shaft 304; a mounting plate 101 is arranged in the center of the top of both sides of the concave frame 1, and the cylinder body of the electric hydraulic push rod 401 is arranged on the mounting plate 101. The electric hydraulic push rod 401 can drive the connecting plate 402 to rise and fall, thereby adjusting the height of the two groups of active traction and cutting structures 3, so that it can cooperate with the driven traction and cutting structure 2 to clamp the carrier tape, and the motor 403 can drive the second connecting shaft 304 to rotate, and then the second connecting shaft 304 drives the active traction roller 301 to rotate.

[0026] Preferably, rectangular through holes 102 are opened on both sides of the concave frame 1, and the second connecting shaft 304 passes through the rectangular through holes 102. The rectangular through holes 102 facilitate the second connecting shaft 304 to move up and down.

On the one hand, this can have a limiting effect on the transmission process of the carrier tape to prevent it from being offset, thereby ensuring the accuracy of the cutting edge of the carrier tape by the knife disc 302 and the matching cutting slot 202; on the other hand, this can prevent the holes of the carrier tape from being squeezed and deformed during the traction process of the carrier tape by the active pulling roller 301 and the driven pulling roller 201, thereby affecting the subsequent use of the carrier tape.

[0028] Working principle: This embodiment provides a carrier tape trimming device. First, when trimming the carrier tape, the carrier tape is placed on two sets of driven traction rollers 201, and then the driving structure 4 drives the two sets of active traction and cutting structures 3 to descend, so that the active traction rollers 301 cooperate with the driven traction rollers 201 to clamp the carrier tape, and then the driving structure 4 drives the active traction and cutting structure 3 to rotate, and the active traction rollers 301 on the active traction and cutting structure 3 rotate, and cooperate with the driven traction rollers 201 to drive the carrier tape to move, so as to achieve the traction effect of the carrier tape, and in the process of traction of the carrier tape, the knife disc 302 on the active traction roller 301 cooperates with the matching cutting groove 202 on the driven traction roller 201 to directly complete the side cutting of the carrier tape, so as to achieve the trimming of the carrier tape, so the driven traction and cutting structure 2 and the active traction and cutting structure 3 realize the integration of traction and trimming of the carrier tape, the structure is simple, and the production cost can be reduced;

On the one hand, this can have a limiting effect on the transmission of the carrier tape to prevent it from shifting, thereby ensuring the accuracy of the cutting edge of the carrier tape by the knife disc 302 and the cooperating cutting slot 202; on the other hand, this can prevent the holes of the carrier tape from being squeezed and deformed during the traction of the carrier tape by the active traction roller 301 and the driven traction roller 201, thereby affecting the subsequent use of the carrier tape.
