Description

Technical Field

[0001] This utility model relates to the field of semiconductor packaging technology, and in particular to an adaptive adjustment mechanism for heat sealing of a carrier tape. Background Technology

[0002] In existing carrier tape heat sealing technology, the installation method of the pressure block and its adjustment in conjunction with the sealing blade are crucial to ensuring heat sealing quality. Currently, the common installation method for carrier tape heat sealing involves tightening the pressure block with upper and lower screws and adjusting the direction of the sealing blade to achieve parallelism between the sealing blade surface and the pressure block surface. While this installation method can meet the basic requirements of heat sealing to a certain extent, it has many inconveniences and defects.

[0003] Specifically, the assembly and disassembly of the pressure block requires repeated tightening of screws, which is cumbersome and time-consuming, significantly reducing production efficiency. Furthermore, ensuring the parallelism between the sealing blade and the pressure block surface requires operators with high skill levels and experience; otherwise, achieving the desired heat-sealing effect is difficult. In addition, the adjustment of the fit between the sealing blade and the pressure block directly affects the appearance of the heat-sealed indentation and the tensile strength; improper adjustment can lead to unstable heat-sealing quality of the carrier tape, or even defective products.

[0004] On the other hand, eliminating the gap on the side of the carrier tape is also a challenge in existing technologies. Currently, a single sheet metal part is typically used for adjustment to eliminate the gap with the side of the carrier tape. However, this adjustment method is not only cumbersome to operate, but the sheet metal part is also prone to heat deformation in high-temperature environments, affecting the adjustment effect. At the same time, operators are easily burned by the high temperature of the sealing blade during the adjustment process, posing a safety hazard.

[0005] It is evident that the existing adjustment mechanism at the heat-sealing point of the carrier tape has problems such as cumbersome operation, difficult adjustment, susceptibility to thermal deformation, and safety hazards. Utility Model Content

[0006] The purpose of this utility model is to provide an adaptive adjustment mechanism for the heat-sealing section of a carrier tape, so as to solve the problems of cumbersome operation, difficult adjustment, and susceptibility to thermal deformation of existing adjustment mechanisms for the heat-sealing section of a carrier tape.

[0007] To achieve the above-mentioned objectives of this utility model, one embodiment of this utility model provides an adaptive adjustment mechanism for the heat-sealing section of a carrier tape, comprising:

[0008] The base has mounting grooves on its upper surface;

[0009] The pressure block is rotatably disposed in the mounting groove. Its top surface is provided with a first guide groove extending along the direction of the carrier belt and an eccentric wheel disposed adjacent to the first guide groove. The eccentric wheel is connected to the pressure block through a mounting shaft and can rotate around the mounting shaft to adjust its radial length extending into the first guide groove.

[0010] A pressure block positioning component is installed on the base and can be switched between locked and released states. When locked, the pressure block positioning component fixes the position of the pressure block, and when released, the pressure block is allowed to rotate or move freely.

[0011] As a further improvement of one embodiment of the present invention, the upper surface of the base is provided with two second guide grooves adjacent to the mounting groove. The two second guide grooves are located on both sides of the mounting groove and are symmetrically arranged. The two ends of the first guide groove are collinearly connected with the two second guide grooves.

[0012] As a further improvement of one embodiment of the present invention, the mounting groove extends perpendicular to the direction of the carrier belt travel, and the bottom wall of the mounting groove is provided with an arc-shaped groove extending along the direction of the carrier belt travel. The bottom surface of the pressure block is provided with a protrusion, and the protrusion has an arc-shaped side surface that cooperates with the inner wall of the arc-shaped groove. The arc-shaped side surface slides on the inner wall of the arc-shaped groove to allow the pressure block to rotate within the mounting groove.

[0013] As a further improvement of one embodiment of the present invention, the inner wall of the arc-shaped groove is provided with a through-hole extending along the direction of the carrier belt travel, and the arc-shaped side is provided with a limiting flange extending along the direction of the carrier belt travel. The limiting flange passes through the long flat hole, and the long flat hole has two side walls that are arranged opposite to each other perpendicular to the direction of the carrier belt travel. When the pressure block rotates in the mounting groove, the limiting flange can move between the two side walls.

[0014] As a further improvement of one embodiment of the present invention, the protrusion and the limiting flange are disposed on the bottom surface of the pressure block opposite to the first guide groove, and the limiting flange is provided with a gas flow channel communicating with the interior of the first guide groove.

[0015] As a further improvement of one embodiment of this utility model, the pressure block positioning component includes a locking screw and a locking pin. The base has a screw hole and a mounting hole connecting the screw hole. The locking screw has a tapered abutting end. The locking pin passes through the mounting hole. The locking screw is disposed in the screw hole in a manner that allows it to move along its axial direction. When the locking screw moves along its axial direction, the abutting end can abut or separate from one end of the locking pin, so that the other end of the locking pin can abut or separate from the pressure block.

[0016] As a further improvement of one embodiment of the present invention, it further includes a limiting cover plate, which is disposed on the top surface of the pressure block and has a limiting part that covers the first guide groove.

[0017] As a further improvement of one embodiment of the present invention, it further includes a sealing knife, wherein the limiting part is provided with an avoidance hole, the sealing knife passes through the avoidance hole and can abut against the pressure block.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] The adaptive adjustment mechanism for the heat-sealed carrier tape provided in this embodiment is simple and easy to operate, making adjustment easy and significantly improving adjustment efficiency. In addition, the pressure block can be moved out of the mounting groove and effectively restrict the position of the carrier tape in the first guide groove, thereby effectively eliminating potential safety risks.

[0049] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0050] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0051] In this utility model, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used in relation to the direction shown in the accompanying drawings, or in relation to the vertical, perpendicular, or gravitational direction of the component itself; similarly, for ease of understanding and description, "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0052] To address the problems of cumbersome operation, difficult adjustment, susceptibility to thermal deformation, and safety hazards in existing carrier tape heat-sealing adjustment mechanisms, this invention provides an adaptive adjustment mechanism for the carrier tape heat-sealing area.

[0053] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Example

[0054] like Figure 1-6 As shown, this embodiment provides an adaptive adjustment mechanism for the heat sealing of a carrier tape, which includes a base 1, a pressure block 2, and a pressure block positioning component 3.

[0055] The upper surface of the base 1 is provided with a mounting groove 11; the pressure block 2 is rotatably disposed in the mounting groove 11, and its top surface is provided with a first guide groove 21 extending along the traveling direction of the carrier belt 100 and an eccentric wheel 22 disposed adjacent to the first guide groove 21. The eccentric wheel 22 is connected to the pressure block 2 through a mounting shaft 221 and can rotate around the mounting shaft 221 to adjust its radial length extending into the first guide groove 21 by changing the eccentricity.

[0056] The pressure block positioning component 3 is set on the base 1 and can be switched between locked and released states. When the pressure block positioning component 3 is locked, it fixes the position of the pressure block 2. When the pressure block is released, it allows the pressure block 2 to rotate or move freely.

[0057] The operation process of the adaptive adjustment mechanism for the heat-sealing section of the carrier tape provided in this embodiment is as follows: The carrier tape 100 is placed in the first guide groove 21. Then, the eccentric wheel 22 is rotated to adjust its radial extension length into the first guide groove 21, thereby limiting the position of the carrier tape 100 in the direction perpendicular to the extension direction of the first guide groove 21. This configuration allows the adjustment mechanism to adapt to carrier tapes 100 of different widths. Next, the pressure block 2 is placed in the mounting groove 11. The pressure block 2 can rotate within the mounting groove 11. When an external force is applied to the pressure block 2, it is forced to rotate within the mounting groove 11 and adjust to the desired position. Then, the pressure block positioning member 3 is adjusted to the locking state, thereby fixing the position of the pressure block 2.

[0058] Understandably, when it is necessary to remove the pressure block 2 and replace the carrier belt 100 installed in the first guide groove 21, the pressure block positioning component can be adjusted to the release state, and then the pressure block 2 can be rotated and removed.

[0059] With the above settings, the operation is simple and easy to adjust, which greatly improves the adjustment efficiency; at the same time, the pressure block 2 moves out of the mounting groove 11 and restricts the position of the carrier belt 100 in the first guide groove 21, which can effectively eliminate safety hazards.

[0060] Furthermore, on the upper surface of the base 1, two second guide grooves 12 are provided near the mounting groove 11. These two second guide grooves 12 are cleverly arranged on both sides of the mounting groove 11 and are symmetrically set to ensure the balance and stability of the structure. The two ends of the first guide groove 21 are collinearly connected with the two second guide grooves 12. This design allows the carrier belt 100 to maintain a smooth and continuous travel path when transitioning from one guide groove to another. This structure not only enhances the guiding performance of the carrier belt 100 during the heat sealing process, but also makes the entire adjustment mechanism more flexible and adaptable, capable of handling carrier belts 100 of different lengths and path requirements, further improving the versatility and practicality of the mechanism.

[0061] Furthermore, the mounting groove 11 extends in a direction perpendicular to the travel of the carrier belt 100, and its structural design fully considers the rotational requirements of the pressure block 2. An arc-shaped groove 111 extending along the travel direction of the carrier belt 100 is specifically provided on the bottom wall of the mounting groove 11. This arc-shaped groove 111 provides the necessary space and support for the rotation of the pressure block 2. Correspondingly, a protrusion 23 is provided on the bottom surface of the pressure block 2, which has an arc-shaped side surface that mates with the inner wall of the arc-shaped groove 111. When the position of the pressure block 2 needs to be adjusted, the arc-shaped side surface of the protrusion 23 slides on the inner wall of the arc-shaped groove 111, thereby driving the pressure block 2 to rotate smoothly within the mounting groove 11. This structural design is simple and practical, ensuring the stability and reliability of the rotation of the pressure block 2.

[0062] Further, refer to Figure 5 and Figure 6 As shown, the inner wall of the arc-shaped groove 111 is ingeniously designed, with a long, flat hole 1111 extending through the base 1 along the traveling direction of the carrier belt 100 on the inner wall. This long, flat hole 1111 provides further restriction and guidance for the rotation of the pressure block 2.

[0063] Specifically, a limiting flange 231 is provided on the arc-shaped side of the pressure block 2, extending along the traveling direction of the carrier belt 100. This limiting flange 231 passes through the elongated flat hole 1111, achieving a limiting fit between the pressure block 2 and the mounting groove 11. The elongated flat hole 1111 has two sidewalls arranged opposite each other perpendicular to the traveling direction of the carrier belt 100. These two sidewalls effectively limit the range of motion of the limiting flange 231. When the pressure block 2 rotates within the mounting groove 11, the limiting flange 231 moves between the two sidewalls, ensuring the stability and accuracy of the pressure block 2's rotation, and also preventing the pressure block 2 from falling off during rotation.

[0064] Preferably, the protrusion 23 and the limiting flange 231 are carefully arranged on the bottom surface of the pressure block 2 and positioned opposite to the first guide groove 21. This arrangement ensures both structural compactness and facilitates the realization of specific functions. One or more gas flow channels 2311 are specially formed on the limiting flange 231, connecting to the interior of the first guide groove 21. The design of this gas flow channel 2311 is ingenious; it perfectly aligns with the gas flow channel on the carrier belt 100, forming a complete gas passage.

[0065] During processing, the gas flow channel 2311 provides a stable adsorption force to the IC in the carrier tape 100, effectively preventing the IC from shaking or shifting during processing. This design not only improves processing accuracy and stability but also ensures the safety and reliability of the IC. Furthermore, the gas flow channel 2311 is highly flexible and can be adjusted and optimized according to different processing requirements and carrier tape 100 specifications.

[0066] Further, refer to Figure 3 , Figure 4 As shown, the pressure block positioning component 3 mainly consists of a locking screw 31 and a locking pin 32. These two parts work together to achieve precise positioning of the pressure block 2. The base 1 has a pre-set screw hole 13 and a mounting hole 14 communicating with the screw hole 13, providing space for the installation of the locking screw 31 and the locking pin 32. The design of the locking screw 31 is particularly special, with its abutting end 311 having a tapered surface. This design allows for better cooperation with the locking pin 32.

[0067] The locking pin 32 passes through the mounting hole 14, while the locking screw 31 is positioned in the screw hole 13 in a manner that allows it to move axially. It is typically fixed to the base 1 via a threaded connection. When the position of the pressure block 2 needs to be adjusted, simply tighten the locking screw 31 to move it axially. During this movement, the abutting end 311 of the locking screw 31 will abut or separate from one end of the locking pin 32, thereby causing the other end of the locking pin 32 to abut or separate from the pressure block 2, thus locking or releasing the pressure block 2.

[0068] The adaptive adjustment mechanism for the heat-sealing section of the carrier tape provided in this embodiment further enhances its stability and reliability by including a limiting cover plate 4. This limiting cover plate 4 is carefully positioned on the top surface of the pressure block 2 and is designed with a limiting portion that covers the first guide groove 21. The position of this limiting portion is precisely calculated to ensure that it completely covers the opening area of ​​the first guide groove 21.

[0069] During processing, various factors may cause the IC to be subjected to external force and pop out of the first guide groove 21. The presence of the limiting part effectively prevents this from happening. It acts like a barrier, firmly confining the IC within the first guide groove 21, ensuring smooth processing and the safety of the IC. This design not only improves the practicality of the mechanism but also further enhances the quality and stability of the product.

[0070] The adaptive adjustment mechanism for the heat-sealing section of the carrier tape provided in this embodiment, in addition to the previously described components, also includes the crucial sealing blade 5. The sealing blade 5 is cleverly designed and integrated with the limiting part, which has a specially provided clearance hole 41 to allow the sealing blade 5 to pass through. After the sealing blade 5 passes through the clearance hole 41, its end can abut against the pressure block 2, forming a direct mechanical action relationship.

[0071] When the pressure block positioning component 3 is in the released state, the sealing knife 5 performs its adjusting function. The sealing knife 5 applies a force to the pressure block 2, allowing the pressure block 2 to rotate within the mounting groove 11. This rotation adjusts the position of the pressure block 2, thereby achieving adaptive adjustment of the heat-sealing point of the carrier tape, improving the flexibility and practicality of the mechanism.

[0072] In summary, the embodiments of this utility model achieve the following technical effects:

[0073] The adaptive adjustment mechanism for the heat-sealed section of the carrier tape provided in this embodiment is simple and easy to operate, making adjustment easy and significantly improving adjustment efficiency. In addition, the pressure block 2 can be moved out of the mounting groove 11 and effectively restrict the position of the carrier tape 100 in the first guide groove 21, thereby effectively eliminating potential safety risks.
