Technical Field

[0001] The utility model belongs to the technical field of carrier tape forming machines, and in particular relates to a slitting device for a carrier tape forming machine. Background Art

[0002] The carrier tape forming machine is mainly used to punch holes in unprocessed carrier tapes. After punching, the carrier tapes will be rewound and collected on the reel to facilitate subsequent processing of the carrier tapes.

[0003] During the material collection process, a press is generally used to provide traction for the carrier tape to keep it in a taut state. When the carrier tape forming machine needs to cut the tape after completing a roll of storage, the carrier tape will lose the support force at the other end due to breakage. The excessive traction force of the press is likely to cause the carrier tape to move to the material collection side and slip off the fixing device, thereby affecting the winding effect of the carrier tape. Utility Model Content

[0004] The utility model provides a slitting device for a carrier tape forming machine, aiming to solve the problem that the carrier tape may move to the receiving side and slip off the fixing device due to excessive traction of a receiving and pressing part when the carrier tape loses the supporting force of the other end at the moment of cutting and breaking, thereby affecting the winding effect of the carrier tape.

[0027] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0028] The utility model embodiment provides a carrier tape forming machine slitting device, such as Figure 1-Figure 5 As shown, the carrier tape forming machine slitting device comprises:

[0029] A base 110, wherein a receiving groove is provided on the base 110, and the carrier tape passes through the base 110 through the receiving groove, and a cutting unit 120 is provided on the top of the receiving groove;

[0030] A front fixing member 130 and a rear fixing member 140, wherein the front fixing member 130 is fixed at one end of the receiving slot, and the rear fixing member 140 is slidable at the other end of the receiving slot;

[0031] The front fixing member 130 includes an outer ring frame 131, a first electric push rod 132 and a front pressure plate 133; the rear fixing member 140 includes a sliding seat 141, a second electric push rod 142 and a rear pressure plate 143. During the cutting process, the second electric push rod 142 pushes the rear pressure plate 143 to hold the carrier tape against the sliding seat 141, and the first electric push rod 132 pushes the front pressure plate 133 to hold the carrier tape against the outer ring frame 131;

[0032] The sliding seat 141 slides in a slide groove 150 provided on the base 110, and a spring 160 is further provided in the slide groove 150. The spring 160 generates a thrust to hold the sliding seat 141 against the end of the slide groove 150 close to the front fixing member 130. The base 110, the front fixing member 130 and the rear fixing member 140 constitute a slitting unit 100.

[0033] The carrier tape wound on the unloading device 400 will be processed by the processing unit 300 and then arrive at the slitting unit 100. After the processing is completed, the carrier tape passes through the front fixing member 130, the cutting unit 120 and the rear fixing member 140 in sequence and is finally wound on the receiving device 200. At the moment of cutting, the spring 160 absorbs the traction force of the unloading device 400 on the carrier tape through elastic deformation. In this process, after the cutting action occurs, the carrier tape will lose the supporting force of the other end due to breakage, and the carrier tape located on the rear fixing member 140 will move to the side close to the receiving device 200 under the action of inertia and the traction force of the receiving device 200. Since this instantaneous traction force is generated, it will be transmitted to the spring 160 in the first time; the spring 160 will offset the traction, thereby preventing the excessive traction force from causing the carrier tape to slip off the rear fixing member 140 in advance;

[0034] As a preferred implementation in this embodiment, the cutting unit 120 includes a guide frame 121, an electric hydraulic push rod 122 and a cutter 123;

[0035] The electric hydraulic push rod 122 is assembled on the guide frame 121. The guide frame 121 includes a top plate and a limiting guide block. The top plate and the limiting guide block are connected by a connecting rod. The limiting guide block is provided with a limiting knife groove. The electric hydraulic push rod 122 extends into between the top plate and the limiting guide block. The cutter 123 is connected to the end of the electric hydraulic push rod 122. The electric hydraulic push rod 122 pushes the cutter 123 to pass through the limiting knife groove to carry out cutting.

[0036] In this embodiment, a cutting table 124 is further provided below the cutting unit 120, and the cutting table 124 supports the carrier tape during the cutting process;

[0037] As a preferred implementation in this embodiment, the side wall of the sliding seat 141 is provided with a guide groove 1412; the side wall of the accommodating groove is provided with a guide rail adapted to the guide groove 1412; the bottom of the sliding seat 141 is provided with a slider 1411, and the slider 1411 slides on the base 110 provided with a slide groove 150; the slider 1411 is provided with a guide column 1413, one end of the spring 160 is nested on the guide column 1413, and the other end of the spring 160 is connected to the end of the slide groove 150 away from the front fixing member 130;

[0038] In this embodiment, the guide rail and the guide groove 1412 are used to ensure the stability of the sliding seat 141 during movement, and the spring 160 absorbs the instantaneous traction force by deformation, thereby reducing the impact of the instantaneous traction force and preventing the carrier belt from falling off the rear fixing member 140;

[0039] The electric hydraulic push rod 122, the first electric push rod 132 and the second electric push rod 142 are all prior art;

[0040] During the processing of the equipment, the carrier tape stops processing, and the first electric push rod 132 on the front fixing member 130 and the second electric push rod 142 on the rear fixing member 140 will synchronously apply pressure to the carrier tape in the stationary state, and then the cutter on the cutting unit 120 will perform the cutting operation. After the cutting is completed, the carrier tape near the side of the receiving device 200 will be subjected to the traction force of the receiving device 200. Under the double action of the sliding action and the elastic action of the rear fixing member 140, the traction force will be absorbed by the spring 160 to the greatest extent, so as to prevent the carrier tape from slipping off the rear fixing member 140;
