Description

Technical Field

[0001] This utility model relates to the field of carrier tape production technology, and in particular to a traction structure for carrier tape forming. Background Technology

[0002] In the field of electronic packaging, carrier tape, as a key material used to carry and transport electronic components, directly affects the packaging and performance of subsequent components. During the carrier tape molding process, the traction structure is an indispensable core component, undertaking the crucial task of stably transporting the molded carrier tape.

[0003] In existing carrier tape forming traction structures, the traction rollers are usually fixed in place. When the traction rollers wear out or need to be replaced with different specifications, the disassembly and installation process is cumbersome, consuming a lot of time and manpower, which seriously affects production efficiency.

[0004] On the other hand, during the molding and traction process, the surface of the carrier tape is prone to adsorbing impurities such as dust and debris. These impurities not only affect the appearance quality of the carrier tape, but may also cause problems such as short circuits and poor contact of electronic components during subsequent packaging. In addition, tension control of the carrier tape during the traction process is also crucial. Excessive tension can easily lead to carrier tape breakage, while insufficient tension will cause the carrier tape to become loose and wrinkled, affecting the molding quality and production stability of the carrier tape.

[0005] Therefore, we propose a traction structure for carrier tape forming. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies. Traction rollers are mostly fixed installations, which are inconvenient to replace and maintain, affecting production efficiency. Carrier belts are prone to adsorbing impurities during forming and traction, affecting appearance quality and potentially causing electronic component failures. Furthermore, improper tension control, whether too high or too low, will adversely affect the forming quality and production stability of the carrier belt.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A traction structure for carrier tape forming includes a fixed base, on which a quick-release traction assembly is mounted. The front of the fixed base is also provided with a vertical adjustment assembly. A dust removal and tension adjustment assembly is provided at the connection of the vertical adjustment assembly. The vertical adjustment assembly is used to drive the dust removal and tension adjustment assembly to perform vertical adjustment movement. The dust removal and tension adjustment assembly is used to remove dust and adjust the tension of the carrier tape when the quick-release traction assembly is traction.

[0013] As a preferred embodiment of this utility model, the carrier belt passes through the interior of the mounting frame and is connected to the traction roller. The air rod is used to drive the pressure plate and foam pad to press down, thereby applying pressure to the carrier belt and adjusting the tension. The air pump delivers compressed air to several nozzles through connecting hoses to remove dust from the carrier belt.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] To facilitate understanding of this utility model, a more comprehensive description of this utility model will be provided below with reference to relevant embodiments, and several embodiments of this utility model will be given. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of this utility model more thorough and complete.

[0022] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items. Example

[0024] like Figure 1-4 As shown, this utility model provides a technical solution: the quick-release traction assembly uses a first drive motor 21 as its power core. A reducer 22 mounted on its left side wall reduces the motor speed and increases torque, providing stable and strong power output to the traction roller 26. The output end of the first drive motor 21 is connected to the rotating shaft 23 via a bearing. The bearing effectively reduces friction during rotation of the rotating shaft 23, ensuring smooth rotation. A fixed limiting plate 25 mounted on the rotating shaft 23 is securely connected to the rotating shaft 23 by welding or high-strength bolts, thus fixing the traction roller 26. The function of the left side position is that the threaded body 24 on the right side of the rotating shaft 23 is adapted to the internal thread of the movable locking block 27. The traction roller 26 is sleeved on the rotating shaft 23, and its left side is in close contact with the fixed limiting plate 25. When it is necessary to install the traction roller 26, the traction roller 26 is sleeved into the rotating shaft 23, and then the movable locking block 27 is screwed onto the threaded body 24. By tightening the movable locking block 27, pressure is applied to the right side wall of the traction roller 26, thereby achieving quick fixation of the traction roller 26. When disassembling, the traction roller 26 can be easily removed by simply twisting the movable locking block 27 in the opposite direction.

[0025] This structural design is based on the principles of mechanical connection and threaded fastening. The fixed limiting plate 25 and the movable locking block 27 form a bidirectional limiting of the traction roller 26. The threaded connection facilitates quick disassembly and assembly, reducing the time cost of equipment maintenance and replacement of the traction roller 26. In actual production, traction rollers 26 of different specifications or wear can be quickly replaced, ensuring the continuity of production and significantly improving production efficiency.

[0026] The core component of the up-and-down adjustment assembly is the lead screw 32 inside the mounting base 31. The input end of the lead screw 32 is connected to the second drive motor 33, which provides rotational power to the lead screw 32. The slider 34 installed on the lead screw 32 has an internal thread that matches the thread of the lead screw 32. The slider 34 is sleeved on the lead screw 32 through a threaded connection. When the second drive motor 33 starts, the lead screw 32 begins to rotate. Due to the threaded transmission relationship between the slider 34 and the lead screw 32, the slider 34 will move up and down along the axial direction of the lead screw 32. The slider 34 is fixed together with the mounting frame 41 by welding, bolting, or other means, thereby driving the mounting frame 41, i.e., the dust removal and tension adjustment assembly, to perform up-and-down adjustment movements.

[0027] This component utilizes the lead screw 32 and nut transmission principle. The rotation of the lead screw 32 is converted into the linear motion of the slider 34 through threaded transmission. This transmission method features high precision and smooth transmission. By controlling the forward and reverse rotation and the number of rotations of the second drive motor 33, the position of the slider 34 can be precisely adjusted. Furthermore, the height of the dust removal and tension adjustment components can be flexibly adjusted according to the specifications, thickness, and production process requirements of different carrier belts, enabling the equipment to adapt to various production needs and enhancing its versatility and adaptability.

[0028] The main body of the dust removal tension adjustment component is the mounting frame 41. The air rod 42 installed on the top of the mounting frame 41 is usually a cylinder or a pneumatic-hydraulic booster cylinder. Its output end is connected to the pressure plate 43. The foam pad 44 attached to the bottom of the pressure plate 43 has good elasticity and cushioning performance, which can avoid damage to the surface of the carrier belt when applying pressure. Several spray nozzles 45 are set on the two side walls inside the mounting frame 41, which are evenly distributed to ensure that the surface of the carrier belt is thoroughly swept. The adsorption collection seat 46 at the bottom of the mounting frame 41 is connected to the negative pressure pump 47 on the front. When the negative pressure pump 47 works, it will generate negative pressure at the adsorption collection seat 46, sucking in and collecting the dust and other impurities blown down. The connecting hose 48 on the right side wall of the mounting frame 41 is connected to the air pump 49. The compressed air generated by the air pump 49 is delivered to the spray nozzle 45 through the connecting hose 48.

[0029] In terms of dust removal, compressed air generated by air pump 49 is blown onto the carrier belt surface in the form of high-speed airflow through nozzle 45, blowing up dust, debris and other impurities attached to the carrier belt surface. At the same time, negative pressure pump 47 collects floating dust through negative pressure adsorption force generated by adsorption collection seat 46, forming a high-efficiency dust removal system that combines "blowing and suction" to effectively remove impurities from the carrier belt surface. In terms of tension adjustment, air rod 42 drives pressure plate 43 and foam pad 44 to press down on the carrier belt by controlling the output pressure. The pressure of air rod 42 is adjusted according to the required tension of the carrier belt, thereby precisely controlling the pressure on the carrier belt and adjusting the tension of the carrier belt. This avoids problems such as breakage, loosening and wrinkling of the carrier belt due to improper tension, ensuring the quality of carrier belt forming and production stability.

[0030] Workflow First, according to production needs, the second drive motor 33 drives the lead screw 32 to rotate, which in turn drives the slider 34 and the dust removal tension adjustment component to move up and down, adjusting the dust removal tension adjustment component to a suitable height.

[0031] Then, the carrier belt is passed through the interior of the mounting frame 41 and connected to the traction roller 26.

[0032] Next, using the quick-release traction assembly, the traction roller 26 is quickly installed on the rotating shaft 23 via the fixed limiting plate 25 and the movable locking block 27. The first drive motor 21 drives the rotating shaft 23 and the traction roller 26 to rotate via the reducer 22, and begins to traction the carrier belt.

[0033] During the traction process, the air pump 49 delivers compressed air to the injection port 45 through the connecting hose 48 to remove dust from the carrier belt. At the same time, the negative pressure pump 47 generates negative pressure adsorption force on the mounting frame 41 through the adsorption collection seat 46 to collect floating dust. The air rod 42 drives the pressure plate 43 and the foam pad 44 to apply pressure to the carrier belt. The tension is adjusted according to the actual situation of the carrier belt to ensure that the carrier belt is formed under appropriate tension.

[0034] When it is necessary to replace the traction roller 26 or adjust the height of the dust removal tension adjustment component, the traction roller 26 can be quickly disassembled or its position adjusted by the up-down adjustment component to meet different production needs.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
