Description

Technical Field

[0001] The utility model relates to the technical field of carrier tape processing, in particular to an automatic feeding and cutting device for carrier tapes. Background Art

[0002] Carrier tape refers to a strip product used in the field of electronic packaging. It has a specific thickness and is mainly used in the electronic component mounting industry. It is used in conjunction with a cover tape (upper sealing tape) to carry and store electronic components such as resistors, capacitors, transistors, and diodes in the pockets of the carrier tape, and the cover tape is sealed on top of the carrier tape to form a closed package to protect the electronic components from contamination and damage during transportation. The carrier tape often needs to be cut during use.

[0003] The patent with publication number CN213320315U discloses an automatic feeding and cutting device for carrier tapes, which includes a base plate, positive and negative screw rods, a conveyor belt, a first motor and a second motor. A support frame is arranged at the top of the base plate, and a conveyor belt is installed on the inner side of the support frame. A second motor is arranged at one end of the support frame through a mounting plate. The nut moving plate of the device drives the pressing block to squeeze the support column, and then the support column is fixed in the empty groove, which is convenient for the operator to fix the position of the support column, thereby facilitating the loading of carrier tapes of different diameters. However, the device has the problem of placing the carrier tape on a fixed shaft between the lifting columns for limit fixing, and then using The first motor and the second motor cooperate with the fixed shaft and the conveyor belt to transfer the carrier tape to the support plate for cutting. However, the lifting column can only be adjusted according to the thickness of the carrier tape at the beginning so that the carrier tape is in contact with the conveyor belt for transmission. However, in the process of the carrier tape being continuously conveyed to the support plate for cutting, the diameter of the carrier tape roll on the carrier disk will become smaller and smaller, which will cause the rotated carrier tape to be less and less fit with the conveyor belt, making it difficult to stably convey and cut the carrier tape, thereby affecting the cutting effect of the carrier tape and even causing the carrier tape to be damaged due to cutting. An automatic feeding and cutting device for carrier tape is proposed to solve the problem that the existing carrier tape cutting device is difficult to stably convey the carrier tape for cutting.

[0024] Furthermore, the top of the roller 7 is flush with the top of the cutting seat 2. The roller 7 is used to ensure that the carrier tape can always be nearly in contact with the cutting seat 2 during the process of the driven mechanism 13 reducing its conveying diameter, thereby ensuring the cutting effect of the carrier tape.

[0025] Furthermore, the vertical plate 9 is located on the outer ring of the slide bar 11, and the top and bottom of the spring 12 are respectively connected to the vertical plate 9 and the bottom of the movable groove 8. When the carrier disc is not installed, the spring 12 is in a normal state, and the carrier disc is fixed between the vertical plates 9 by using the fastening mechanism 10, and then the top seat 6 in the slide groove 5 is pushed to move multiple rollers 7 to the bottom of the carrier disc so that it contacts the carrier and lifts up the carrier disc. In conjunction with the spring 12 on the slide bar 11 in the movable groove 8, there is always a downward pulling force on the carrier disc, ensuring that the carrier is always nearly in contact with the cutting seat 2 during subsequent cutting.

[0026] Furthermore, the fastening mechanism 10 consists of a swivel seat 101, an electric push rod 102 and a fastening disk 103. The swivel seat 101 is mounted on the top of the vertical plate 9, the electric push rod 102 is fixed at one end of the swivel seat 101, and the other end of the electric push rod 102 is fixedly connected to the fastening disk 103. When the carrier disk is fixed between the vertical plates 9, the carrier disk can be placed in the middle position of the two fastening disks 103, and then the electric push rod 102 is turned on to drive the fastening disk 103 to clamp and fix the carrier disk 103. In conjunction with the swivel seat 101, the driving mechanism 13 can be used to transport the carrier tape for cutting, thereby improving the convenience of installing and disassembling the carrier disk of this automatic loading and cutting device.

[0027] Furthermore, the driving mechanism 13 is composed of a U-shaped frame 131, a driving roller 132, a pressure roller 133, a rotating shaft 134, a motor 135, a pressure groove 136, a pressure block 137 and a compression spring 138. The U-shaped frame 131 is fixed on the top of the cutting table 1, the driving roller 132 is fitted with the pressure roller 133 and both are arranged in the inner cavity of the U-shaped frame 131 using the rotating shaft 134. One end of the carrier tape passes through the two driving mechanisms 13 and the cutting frame 3. The carrier tape can be cut while being conveyed in cooperation with the hydraulic cutting knife 4. After cutting, the driving mechanism 13 on one side continues to compress and convey the carrier tape to improve the continuity of the carrier tape cutting.

[0028] Furthermore, a motor 135 is fixedly connected to one end of the U-shaped frame 131 , and an output shaft of the motor 135 is fixedly connected to a rotating shaft 134 on which a driving roller 132 is installed, and a top of the driving roller 132 is slightly higher than the cutting seat 2 .

[0029] Furthermore, both ends of the U-shaped frame 131 are penetrated by a pressing groove 136, and the inner cavity of the pressing groove 136 is provided with a pressing block 137 and a compression spring 138. The pressing roller 133 is arranged between the two pressing blocks 137 by means of a rotating shaft 134. When the driving mechanism 13 is used for transportation, the motor 135 can be turned on, and the rotating shaft 134 can be used to drive the driving roller 132. When the carrier tape is continuously transported through the cutting frame 3, in conjunction with the compression spring 138 on the pressing block 137 in the pressing groove 136, the pressing roller 133 can be used to press the carrier tape against the driving roller 132 according to the thickness of the carrier tape, thereby improving the stability of the carrier tape during transportation and cutting.

[0030] Working principle: When using this automatic loading and cutting device for carrier tapes, the carrier tape disc is fixed between the vertical plates 9 by means of a fastening mechanism 10, and then the top seat 6 in the push slide 5 is used to move the multiple rollers 7 to the bottom of the carrier tape disc so that it contacts and lifts up the carrier tape. In conjunction with the spring 12 on the slide bar 11 in the movable groove 8, there is always a downward pulling force on the carrier tape disc, so that the carrier tape can always fit with the cutting seat 2 during the process of the diameter of the carrier tape being reduced by the driven mechanism 13, thereby solving the problem that the existing carrier tape cutting device is difficult to stably convey the carrier tape for cutting.
