DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example: See Figure 1-4A cutting device for a carrier tape for packaging electronic components comprises a cutting table 1, the top of which is fixedly connected with a mounting mechanism 2, a limiting frame 3 and two fixed frames 11 in sequence, the inner cavity of the limiting frame 3 is provided with a U-shaped frame 4, the inner cavity of the U-shaped frame 4 is rotatably provided with a pressure roller 5, the rotating pressure roller 5 is arranged in the inner cavity of the U-shaped frame 4 by a rotating shaft 6, the outer ring of one end of the rotating shaft 6 is fixedly connected with a turning handle 7, both ends of the limiting frame 3 are penetrated with a moving groove 8, the rotating shaft 6 is located in the inner cavity of the moving groove 8, the top of the limiting frame 3 is provided with a telescopic rod 9 and a spring 10, a cutting mechanism 12 and an adjusting plate 13 are provided between the two fixed frames 11, both ends of the adjusting plate 13 are fixedly connected with an adjusting block 14, and the top of the cutting table 1 is provided with a scale 15.

[0024] Furthermore, the spring 10 is located on the outer ring of the telescopic rod 9, and the top and bottom of the telescopic rod 9 and the spring 10 are fixedly connected to the limit frame 3 and the U-shaped frame 4 respectively. The spring 10 is in a compressed state, and the transfer roller 5 is made of elastic rubber material and contacts the cutting table 1. The spring 10 on the outer ring of the telescopic rod 9 ensures that the transfer roller 5 always has a certain downward pressure, and then it can be tightened and limited according to the thickness of the carrier tape, while ensuring that when the transfer roller 5 made of elastic rubber material is rotated, the carrier tape can be smoothly transported and cut under the action of the pressure of the transfer roller 5 and the friction between the two.

[0025] Furthermore, the adjustment block 14 is located in the inner cavity of the fixing frame 11 and there is a certain relatively static friction between the two. The left side of the adjustment block 14 is flush with the zero scale line of the scale 15, ensuring that the adjustment plate 13 can be stationary under the action of the friction between the adjustment block 14 and the fixing frame 11 after the position is adjusted, which is convenient for subsequent blocking of the carrier for cutting.

[0026] Furthermore, the mounting mechanism 2 includes a stand 201 , an inner cavity of the stand 201 is provided with a rotating seat 202 , there is a certain friction force between the rotating seat 202 and the stand 201 , and one end of the rotating seat 202 is fixedly connected to a rotating rod 203 .

[0027] Furthermore, the outer ring of the rotating rod 203 is fixedly connected with multiple fastening springs 204, and the outer ring of the rotating rod 203 is provided with three evenly distributed fastening arc plates 205, and the fastening arc plates 205 are fixedly connected with the fastening springs 204. The three fastening arc plates 205 are moved toward the rotating rod 203 to compress the fastening springs 204, and then the carrier disc is put on the fastening arc plates 205 and cooperates with the fastening springs 204 to limit the installation of the carrier disc on one side of the stand 201. The friction between the rotating seat 202 and the stand 201 ensures that the carrier can be slowly and stably pulled out from the carrier disc, thereby improving the stability of subsequent carrier conveying and cutting.

[0028] Furthermore, the cutting mechanism 12 includes a cutting knife 121, which is located between the two fixed frames 11. A groove 122 is provided on the top of the fixed frame 11. A moving block 123 and a second spring 124 are provided in the inner cavity of the groove 122. The moving block 123 is fixedly connected to the cutting knife 121. The distance from the cutting knife 121 to the zero scale of the scale 15 is a fixed value. The sum of the position of the adjustment plate 13 and the distance from the cutting knife 121 to the zero scale of the scale 15 is the cutting length of the carrier tape. When the carrier tape is transported to the cutting position where it contacts the adjustment plate 13, the cutting knife 121 can be directly pressed to cut the carrier tape, and the cutting knife 121 can reset itself in cooperation with the moving block 123 and the second spring 124 in the groove 122, which is convenient for the subsequent transportation and cutting of the carrier tape.

[0029] Furthermore, an adjustment groove 16 is opened on one side of the limit frame 3, and a limit clamp 17 is set in the inner cavity of the adjustment groove 16. One side of the limit clamp 17 is in contact with the fixed frame 11. There is a certain friction between the limit clamp 17 and the adjustment groove 16 and the fixed frame 11. When the carrier tape is pulled out and passes through the bottom of the transfer roller 5, there is no need to control the position of the carrier disk on the mounting mechanism 2. The two limit clamps 17 in the adjustment groove 16 on one side of the limit frame 3 are moved to contact the two ends of the carrier tape. The friction between the limit clamp 17 and the adjustment groove 16 and the fixed frame 11 is used to fix the position of the limit clamp 17 by itself, so it can be limited according to the width of the carrier tape, thereby further improving the stability of the carrier tape conveying and cutting.

[0030] Working principle: When using this cutting device for the carrier tape for packaging electronic components, use the mounting mechanism 2 to install the carrier tape disc, then move up the U-shaped frame 4 to pull out the carrier tape and pass it through the bottom of the transfer roller 5, and cooperate with the outer ring spring 10 of the telescopic rod 9 to press and limit the carrier tape. According to the cutting length requirements, use the inner adjustment block 14 of the fixed frame 11 and the scale 15 to adjust the position of the adjustment plate 13. Use the turning handle 7 to drive the transfer roller 5 on the rotating shaft 6 to rotate, so that the carrier tape automatically moves to contact with the adjustment plate 13, and cooperates with the cutting mechanism 12 to complete the cutting, which solves the problem that the existing carrier tape cutting device is difficult to quickly and accurately cut the carrier tape.
