Description

Technical Field

[0001] The utility model relates to the technical field of carrier tape processing, in particular to a positioning and clamping mechanism for carrier tape processing. Background Art

[0002] Carrier tape is a material used for packaging and transporting electronic components, typically used in surface mount technology (SMT) applications. It is typically made of plastic and features specific grooves or holes to secure and protect electronic components such as resistors, capacitors, and integrated circuits. The carrier tape requires a positioning and clamping mechanism during the rewinding process.

[0003] A search revealed Chinese patent application number CN216686968U, which discloses a positioning and clamping mechanism for carrier tape processing. The mechanism comprises a base plate and a rotating mechanism. Fixed feet are fixedly mounted near the four corners of the base plate's lower end. A left and right circular discs are provided on the upper and left sides of the base plate, respectively. A winding column is fixedly connected between the left and right circular discs. The rotating mechanism is disposed on the outer sides of the left and right circular discs. A fixing mechanism is disposed on the outer sides of the winding column. The carrier tape is disposed within the fixing mechanism.

[0004] Although the above patent sets a rotating mechanism and turns on the rotating motor so that the rotating shaft rotates along the rotating groove, the rotating rod rotates inside the fixed block, so that the left disc, the right disc and the winding column rotate, and the carrier tape begins to wind along the winding column, the carrier tape winding and positioning of most current equipment is relatively troublesome. The application of this device effectively avoids the above problems and improves the practicality of the equipment, but there are still the following deficiencies during use: 1. The device only clamps and fixes the carrier tape through the simple magnetic attraction principle of a magnet, which is easy to fall off during the carrier tape winding process, affecting the processing process and even damaging the carrier tape; 2. The device is only equipped with a left disc and a right disc to perform winding operations on the same batch of carrier tapes. However, there is a lack of limiting structure between the individual carrier tapes of the same batch, which easily causes the carrier tape to be skewed during winding and the winding effect is poor.

[0005] Therefore, there is an urgent need for a positioning and clamping mechanism for carrier tape processing to solve the above problems. Utility Model Content

[0006] The purpose of the present invention is to provide a positioning and clamping mechanism for carrier tape processing to solve the problems raised in the above-mentioned background technology.

[0007] In order to achieve the above-mentioned purpose of the invention, the present invention provides the following technical solutions:

[0008] A positioning and clamping mechanism for carrier tape processing, comprising a winding column, wherein the winding column is provided in multiple groups, and the outer wall of the winding column is detachably connected to a rotating rod, and further comprising:

[0009] The clamping assembly comprises an adjusting rod rotatably connected to the inner wall of the card seat, the top wall of the adjusting rod is fixedly connected to a one-way screw, the outer wall of the one-way screw is threadedly connected to a lifting plate, the outer wall of the lifting plate is fixedly connected to a symmetrically distributed fixing rod, the outer wall of the fixing rod is slidably connected to a symmetrically distributed slide, the outer wall of the fixing rod is provided with a strong spring, the outer wall of the slide is fixedly connected to a symmetrically distributed connecting frame, the end of the connecting frame away from the slide is rotatably connected to a slider, and the slider is slidably connected to the winding column, and the outer wall of the slider is fixedly connected to a clamping block;

[0010] A detachable component is provided on the outer wall of the winding column;

[0011] The width limit adjustment component is arranged on the inner wall of the winding column.

[0012] As a preferred technical solution of the present application, the detachable component includes a limit plate rotatably connected to the outer wall of the winding column, the outer wall of the limit plate is slidably connected to a symmetrically distributed clamping seat, and the clamping seat is fixedly connected to the winding column, the outer wall of the limit plate is also slidably connected to a symmetrically distributed clamping block, the inner wall of the limit plate is threadedly connected to a lever, the outer wall of the lever is rotatably connected to a positioning block, and the positioning block is located between the clamping seat and the inner wall of the block.

[0013] As a preferred technical solution of the present application, the width limit adjustment assembly includes a T-frame symmetrically slidably connected to the inner wall of the winding column, the outer wall of the T-frame is fixedly connected to the limiting disc, the inner wall of the T-frame is threadedly connected to a bidirectional screw, and the bidirectional screw is rotatably connected to the winding column, the outer wall of the bidirectional screw is fixedly connected to a main connecting block, the outer wall of the main connecting block is provided with a connecting groove, the inner wall of the connecting groove is slidably connected to a secondary connecting block, and the secondary connecting block is fixedly connected to the adjacent bidirectional screw.

[0014] As a preferred technical solution of the present application, the clamping block is fixedly connected to the winding column, and the clamping block is slidably connected to the clamping seat.

[0015] As a preferred technical solution of the present application, the strong spring is fixedly connected to the slide plate, and the end of the strong spring away from the slide plate is fixedly connected to the fixing rod.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] In the scheme of this application:

[0018] 1. A slider that slides along the curved structure of the winding column slides in opposite or opposite directions along the fixed rod as the height of the connecting frame and the slide plate changes, thereby adjusting the position of the clamping block and achieving clamping and fixing of the carrier tape. Since the slide plate and the connecting frame are height-adjusted by the threaded cooperation of the lifting plate and the one-way screw, the threaded structure can achieve a limit locking function, improving the firmness of the clamping and preventing the carrier tape from falling off during winding. This solves the problem of the existing technology that clamps the carrier tape by simple magnetic attraction, which is prone to falling off during the winding process, affecting the processing process and even damaging the carrier tape.

[0019] 2. The bidirectional screw rotates, and the threaded engagement between the bidirectional screw and the T-frame drives the T-frame to slide on the winding column, thereby adjusting the position of the limiting disc, thereby achieving width limit for carrier tapes of different widths. This prevents the carrier tape from being skewed during the winding process, which affects the winding effect. This solves the problem in the prior art of the lack of a limiting structure between individual carrier tapes in the same batch, which easily leads to skewed carrier tapes and poor winding effect.

[0020] 3. The connection between two adjacent winding columns is achieved by setting a limit disk that can be rotated and inserted into the card block and the card seat, and the positioning block is inserted between the card seat and the card block to further limit the position, thereby improving the firmness of the connection. At the same time, when adjacent winding columns are connected, the auxiliary connecting block slides into the connecting groove through the docking, which can realize the connection between the bidirectional screws on the inner walls of adjacent winding columns, realize the synchronous adjustment of multiple limit disks, shorten the adjustment time when winding the same batch of carrier tapes, and improve the winding efficiency.
