[0037] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0038] Currently, most of the methods for cutting tape in the production workshop are to cut it manually with a knife, which increases the risk of scratching workers. Moreover, only one section of tape can be obtained in one cut, limiting the production efficiency and increasing the time cost.

[0039] To solve the above problems, this embodiment provides a tape cutting device, which simplifies the operation process of tape cutting, improves safety, reduces the time cost of production, and simplifies the structure of the cutting device.

[0040] Specifically, as Figure 1-2As shown in the figure, the tape cutting device includes a fixing frame 1, a cutting knife 2, a connecting rod assembly 3, a driving member 4 and a mounting plate 5. The mounting plate 5 extends in the first direction. A plurality of fixing frames 1 are arranged on the mounting plate 5 in a position-adjustable manner along the first direction, and a receiving groove 11 is formed at the end of each fixing frame 1. That is to say, the receiving groove 11 is formed on the side of the fixing frame 1 away from the mounting plate 5. A plurality of cutting knives 2 are respectively arranged in a plurality of corresponding receiving grooves 11. The cutting knife 2 has a storage position placed in the receiving groove 11 and a cutting position protruding from the receiving groove 11. Each cutting knife 2 is connected to the connecting rod assembly 3. The driving member 4 can drive the connecting rod assembly 3 to drive the cutting knife 2 to switch between the storage position and the cutting position. The tape is arranged at the opening of the receiving groove 11. The driving member 4 drives the connecting rod assembly 3 to move the cutting knife 2 from the storage position to the cutting position and cut the tape, which simplifies the operation process of tape cutting, avoids manual use of a blade to cut the tape, and improves safety. Moreover, by providing a plurality of fixing frames 1, multiple tapes can be cut at one time, which improves practicability, further reduces the cutting time, reduces the time cost of production, and the position of the fixing frame 1 can be adjusted along the first direction, which is beneficial to moving the fixing frame 1 according to the required length of the tape and adjusting the distance between two adjacent fixing frames 1 to cut tapes of different lengths. Using a connecting rod to connect the driving member 4 and the cutting knife 2 simplifies the structure of the cutting device, simplifies the production process of the tape cutting device, and reduces costs.

[0041] Specifically, the connecting rod assembly 3 includes a first connecting rod 31, a second connecting rod 32 and a third connecting rod 33 that are sequentially hinged. The first connecting rod 31 and the third connecting rod 33 are of equal length and parallel. The axis of the second connecting rod 32 extends in the first direction, and the second connecting rod 32 slidably penetrates through the cutting knife 2. One end of the first connecting rod 31 away from the second connecting rod 32 is fixedly connected to the output end of the driving member 4, which simplifies the structure of the cutting device, simplifies the production process of the tape cutting device, and reduces costs. Through the mutually hinged connecting rod assembly 3, the first connecting rod 31 and the third connecting rod 33 can rotate relative to the second connecting rod 32, and when the first connecting rod 31 and the third connecting rod 33 rotate relative to the second connecting rod 32, the second connecting rod 32 can drive the cutting knife 2 to move relative to the fixing frame 1. The receiving groove 11 of the fixing frame 1 can limit the cutting knife 2 to move only linearly relative to the fixing frame 1. And when the position of the fixing frame 1 is fixed, the second connecting rod 32 slidably penetrates through the cutting knife 2, which also ensures that when the cutting knife 2 switches between the storage position and the cutting position, the cutting knife 2 moves only linearly relative to the fixing frame 1. When the cutting knife 2 is placed in the receiving groove 11, it is in the storage position. When the cutting edge of the cutting knife 2 protrudes from the receiving groove 11, it is in the cutting position, that is, the cutting knife 2 moves from the storage position to the cutting position to cut the tape; and moves from the cutting position to the storage position to store the cutting knife 2.

[0042] Furthermore, the driving member 4 includes a driving motor. One end of the first connecting rod 31 away from the second connecting rod 32 is fixed to the output shaft of the driving motor. Using the driving motor to provide power for the connecting rod assembly 3 improves the degree of automation. In this embodiment, the output shaft of the driving motor can rotate around its own axis and can drive the first connecting rod 31 to rotate.

[0043] Preferably, a support seat 6 is further provided on the mounting plate 5. The support seat 6 is provided with a through hole, and a rotating rod 61 is rotatably inserted through the through hole. The rotating rod 61 is parallel to the output shaft of the driving motor. One end of the third connecting rod 33 away from the second connecting rod 32 is fixed to the end of the rotating rod 61. The support seat 6 is used to support the other end of the connecting rod assembly 3, so that the connecting rod assembly 3 can drive the cutter 2 to move more stably. The first connecting rod 31, the second connecting rod 32 and the third connecting rod 33 form three sides of a parallelogram, and the second connecting rod 32 is parallel to the mounting plate 5. When the output shaft of the driving motor rotates, the first connecting rod 31 and the third connecting rod 33 can rotate relative to the second connecting rod 32, and the second connecting rod 32 can drive the cutter 2 to move linearly relative to the fixed frame 1. The cutter 2 switches between the storage position and the cutting position, which simplifies the structure of the cutting device, simplifies the production process of the tape cutting device, and reduces the cost.

[0044] Furthermore, the driving member 4 is also arranged on the mounting plate 5. This improves the integrity of the tape cutting device and the modularity of the structure, facilitating installation and movement.

[0045] When cutting the tape, the output shaft of the driving motor rotates by a preset angle from the initial position, so that the cutter 2 placed in the receiving groove 11 in the storage position moves towards the opening of the receiving groove 11 to the cutting position to cut the tape. After the cutting is completed, the output shaft of the driving motor rotates by a preset angle in the opposite direction, and the output shaft returns to the initial position, so that the cutter 2 moves from the cutting position into the receiving groove 11 to the storage position.

[0046] In this embodiment, the first connecting rod 31 and the third connecting rod 33 are respectively hinged to the two end portions of the second connecting rod 32, and the driving motor and the support seat 6 are arranged at both ends of the plurality of fixed frames 1. In other embodiments, the first connecting rod 3 and the third connecting rod 33 can also be hinged to the middle part of the second connecting rod 32, which is not limited herein.

[0047] Preferably, two sets of connecting rod assemblies 3 are symmetrically provided. The extending direction of the receiving groove 11 is perpendicular to the first direction, and the receiving groove 11 penetrates both sides of the fixed frame 1. Both ends of the cutter 2 extend out of the receiving groove 11, and both ends of the cutter 2 are respectively connected to the second connecting rods 32 of the two sets of connecting rod assemblies 3. By providing two sets of connecting rod assemblies 3 and both ends of the cutter 2 are connected to the second connecting rod 32, the tape cutting device operates more stably during cutting.

[0048] In this embodiment, the drive motor includes a biaxial motor. The two first linkages 31 of the two sets of linkage assemblies 3 are respectively connected to the two output shafts of the biaxial motor. Using a biaxial motor reduces the number of parts, decreases the weight, and simplifies the structure. Among them, the output shafts of the biaxial motor can rotate around their own axes and can drive the first linkages 31 to rotate. In other embodiments, the drive motor may also include two uniaxial motors arranged in opposite directions, and the axes of the two output shafts are collinear.

[0049] In this embodiment, the rotating rod 61 passes through the support seat 6, that is, both ends of the rotating rod 61 extend out of the support seat 6 and are respectively connected to the two third linkages 33 of the two sets of linkage assemblies 3.

[0050] In this embodiment, a guiding strip 51 protrudes along the first direction on the mounting plate 5, and the fixing frame 1 can slide along the guiding strip 51, which is beneficial for moving the fixing frame 1 according to the required length of the tape, adjusting the distance between adjacent two fixing frames 1, and cutting tapes of different lengths.

[0051] In this embodiment, a guiding groove 12 is formed on the surface of the fixing frame 1 facing the mounting plate 5, and the guiding strip 51 is placed in the guiding groove 12, and the guiding groove 12 and the guiding strip 51 are in clearance fit, which simplifies the structure of the sliding connection. Moreover, the guiding groove 12 and the guiding strip 51 are in clearance fit, which is beneficial for sliding the fixing frame 1 along the guiding strip 51, and also facilitates detaching the fixing frame 1 from the mounting plate 5, and is convenient for adjusting the number of fixing frames 1 according to the number of required tape segments cut by the tape cutting device at one time.

[0052] In other embodiments, a lead screw may also be provided on the mounting plate 5, and the fixing frame 1 is screwed to the lead screw, or other structural forms that can enable the fixing frame 1 to move linearly along the first direction are not limited herein.

[0053] Preferably, a locking member 13 is provided on the side wall of the guiding groove 12. The locking member 13 is used to fix the position of the fixing frame 1 on the guiding strip 51, which is beneficial for cutting tapes of the required length, avoids the fixing frame 1 from shaking on the mounting plate 5, avoids the length of the cut tape not meeting the requirements, and reduces material waste. In addition, when the tape cutting device is in an inclined state, it is convenient to fix the position of the fixing frame 1 on the mounting plate 5, improving the usability.

[0054] In this embodiment, the locking member 13 is a locking bolt. The locking bolt passes through the side wall of the guiding groove 12 and abuts against the guiding strip 51. And two locking bolts are provided.

[0055] For easy understanding, the usage method of the tape cutting device provided in this embodiment is as follows:

[0056] First, according to the number of tape segments required for each cutting and the length of each tape segment, adjust the number of fixing frames 1 and the distance between two adjacent fixing frames 1. Secondly, attach the tape to the opening of the receiving groove 11 on the fixing frame 1. Thirdly, rotate the driving motor by a preset angle to switch the cutting knife 2 from the storage position to the cutting position and cut the tape. Then, rotate the driving motor in the opposite direction by a preset angle to switch the cutting knife 2 from the cutting position to the storage position and retract the cutting knife 2 into the receiving groove 11. Finally, complete the cutting and remove the tape.

[0057] In this embodiment, the tape cutting device further includes an electric control box 7. A controller is provided inside the electric control box 7. The controller has two functions. One is to be able to control the output shaft of the driving motor to rotate by a preset angle from the initial position to switch the cutting knife 2 from the storage position to the cutting position. The other is to be able to control the output shaft of the motor to rotate back to the initial position to switch the cutting knife 2 from the cutting position to the storage position. A control button can also be provided outside the electric control box 7. Pressing the control button enables the controller to complete the above two functions.

[0058] This embodiment also provides a production line, including a tape and the above tape cutting device. The production line provided with the tape cutting device can simplify the tape cutting process in production and improve production efficiency. And by attaching the tape cutting device to the production equipment, the occupied space is reduced and the cleanliness of the production line is improved. Specifically, the tape is attached to the opening of the receiving groove 11, and the cutting edge of the cutting knife 2 faces the tape.

[0059] The production line further includes production equipment, and the tape cutting device is attached to the production equipment. Attaching the tape cutting device to the production equipment reduces the occupied space and improves the cleanliness of the production line. In this embodiment, double-sided tape is provided on the bottom surface of the mounting plate 5, which can directly paste the tape cutting device on the production equipment, improving the convenience and practicality of use.
