[0002] In the field of electronic manufacturing, SMD carrier tape forming technology is a crucial step in the production of surface mount devices (SMD). Current technologies typically involve heating, forming, and drilling steps, but solutions from different manufacturers suffer from complex structures and cumbersome operations. For example, traditional equipment requires each station to be operated step-by-step, resulting in low efficiency and a lack of synchronized power source design, making automated assembly line operations difficult. Furthermore, the existing technology suffers from insufficient matching between station lengths, carrier tape positions, and connecting tapes, affecting processing accuracy. Although some equipment has attempted improvements, the following problems still exist:

[0003] 1. Poor module coordination: The heating, forming, and punching modules operate independently, increasing equipment size and energy consumption;

[0004] 2. Insufficient drilling precision: Misalignment between the cutting edge structure and the through hole can easily lead to damage to the carrier tape;

[0028] Please see Figures 1 to 3A hot roller mechanism for producing SMD carrier tape according to an embodiment of the present invention includes: a main body (1) divided into first to fourth regions along the material travel direction; a raw material guide roller (2) disposed in the first region; and a preheating device (3) disposed in the second region. The preheating device (3) includes a preheating roller assembly (31), a hot air gun (32), and a roller drum (33). The preheating roller assembly (31) receives carrier tape raw material from the raw material guide roller (2), the roller drum (33) receives preheated carrier tape raw material, and the hot air gun (32) generates hot air from the roller drum. The gun muzzle points to the roller drum (33); the transport guide wheel (4) located in the third area is used to transport the carrier belt output by the roller drum (33); the punching device (5) located in the fourth area includes a workbench (51) and a punch (52), the workbench (51) is fixed to the main body (1) by reinforcing ribs; the slitting and conveying device (6) includes a fixed platform (61) and a slitting wheel (62), the fixed platform (61) is provided with multiple walkways (63), and the slitting wheel (62) is provided with blades (64) corresponding to the walkways (63).

[0029] This device is divided into four functional areas by the main body (1). The carrier belt raw material is input from the raw material guide wheel (2) in the first area and then undergoes preheating, conveying, punching and slitting processes in sequence. In the preheating device (3), the preheating roller group (31) pulls the carrier belt through the coordinated traction of multiple rollers, and the hot air gun (32) blows hot air to the roller drum (33) to make the carrier belt soften evenly by heating. When the preheated carrier belt is sent to the punching device (5) by the conveying guide wheel (4), the punch (52) punches the carrier belt through the reciprocating motion driven by the crank. The reinforcing rib design of the worktable (51) ensures the stability of punching. Finally, the slitting and conveying device (6) cuts the carrier belt into the required width along the guideway (63) through the blade (64) of the slitting wheel (62) to avoid slitting deviation. This structure fully covers the core process flow of carrier belt production, realizes efficient continuous production, and improves production efficiency through integrated process design.

[0030] Please see Figures 1 to 3 In another embodiment, the preheating roller assembly (31) includes three preheating rollers (311) arranged in a triangle, and the tilt angle of the top preheating roller (311a) and the preheating roller (311b) near the roller drum (33) is consistent with the nozzle angle of the hot air gun (32).

[0031] The three preheating rollers (311) in the preheating roller assembly (31) are arranged in a triangle. The tilt angles of the top roller (311a) and the roller (311b) closest to the roller drum (33) are parallel to the nozzle angle of the hot air gun (32), forming a cooperative guiding path. During operation, the carrier material travels in an "S" shape in the triangular roller assembly, increasing the heating area; the airflow from the hot air gun (32) evenly covers the surface of the roller drum (33) along the tilted path, reducing heat loss and improving preheating uniformity and thermal energy utilization.

[0032] Please see Figures 1 to 3 In another embodiment, the angle between the nozzle of the hot air gun (32) and the horizontal direction is 30°~45°.

[0033] The angle between the nozzle of the hot air gun (32) and the horizontal direction is controlled within the range of 30°~45°, so that the hot air accurately covers the surface of the roller drum (33), avoids the airflow from scattering the carrier belt or the heat from being excessively concentrated in a local area, optimizes the hot air coverage area, and reduces energy waste.

[0034] Please see Figures 1 to 3 In another embodiment, the transport guide wheel (4) consists of two parallel guide wheels.

[0035] Two parallel guide rollers (4) are arranged side by side in the third area. After the carrier belt is output from the roller drum (33), it is synchronously pulled by the two guide rollers to maintain uniform speed and avoid the carrier belt deviation caused by uneven force on a single guide roller, thereby improving the stability of the transport.

[0036] Please see Figures 1 to 3 In another embodiment, the punch (52) is driven by a crank mechanism and has a pin (521) at its bottom.

[0037] The punch (52) is driven by a crank mechanism, which makes the punch (52) reciprocate in the vertical direction. The bottom pin (521) penetrates the carrier belt to form a precise hole during punching. The crank motion can convert the rotation drive of the motor into a linear punching action, making the punching efficient and precise, and adaptable to high-speed production.

[0038] Please see Figures 1 to 3 In another embodiment, the edge end of the fixed platform (61) is provided with a groove (611), and the edge end of the cutting wheel (62) is provided with a disc (621) that matches the groove (611), forming a closed structure to prevent the carrier tape from overflowing.

[0039] The groove (611) on the edge of the fixed platform (61) is nested with the disc (621) on the edge of the slitting wheel (62). When the slitting wheel (62) rotates, the gap between the slitting wheel (62) and the fixed platform (61) is completely sealed, preventing the material on the side of the carrier belt from splashing outward during slitting, thus avoiding carrier belt slitting contamination and material waste.

[0040] Please see Figures 1 to 3 In another embodiment, the number of blades (64) is equal to the number of walkways (63), and the center line of each blade (64) coincides with the center line of the corresponding walkway (63).

[0041] The number of blades (64) on the slitting wheel (62) is the same as the number of walkways (63), and the center line of the blades (64) is precisely aligned with the center line of the walkway (63). During slitting, the carrier belt travels along the walkway (63) and is cut by the blades (64) at the center position, ensuring uniform slitting width and improving slitting accuracy and product consistency.

[0042] Please see Figures 1 to 3 In another embodiment, the surface of the slitting wheel (62) is made of hardened tungsten steel.

[0043] The blade (64) of the slitting wheel (62) is made of hardened tungsten steel, which improves the wear resistance and cutting sharpness of the blade (64), reduces the replacement frequency due to wear, extends service life, and reduces maintenance costs.

[0044] Please see Figures 1 to 3 In another embodiment, the end of the ejector pin (521) is a tapered structure.

[0045] The end of the ejector pin (521) is machined into a tapered shape, which can quickly penetrate the carrier belt during punching and reduce burrs on the punching edge, improve punching quality, and reduce secondary finishing processes.

[0046] Please see Figures 1 to 3 In another embodiment, the three preheating rollers (311) are spaced equally, with an adjacent spacing of 10-15 cm.

[0047] The spacing between the three preheating rollers (311) is set to 10~15cm to ensure uniform tension of the carrier belt during operation, avoid excessive slack in the carrier belt due to excessive spacing or excessive friction due to excessive spacing, optimize material stress, and improve the quality of carrier belt forming.

[0048] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
