Description

Technical Field

[0001] This utility model relates to the field of semiconductor packaging, and specifically to a transmission device. Background Technology

[0002] In semiconductor packaging manufacturing, the transfer of materials such as chips and circuit boards is a crucial step in achieving efficient production. However, with the increasing complexity of material properties, such as warpage, existing transfer devices have revealed numerous problems that urgently need to be addressed when handling such materials.

[0003] First, due to the irregular shape of warped materials, the contact area between the material and the support platform is significantly reduced. Normally, sufficient contact between the material and the support platform is fundamental to ensuring stable conveying. However, during conveying, the edges or localized areas of warped material may not adhere tightly to the support platform, resulting in a substantial reduction in the contact area. This poor contact can easily cause the material to slip, deviate, or stall during conveying, thus affecting the stability and accuracy of the conveying process.

[0004] Secondly, warped materials may interfere with the material box track when entering the box. Existing conveyor systems are typically designed for conveying and storing flat materials, but warped materials have poor compatibility with the box track. During conveying, the edges or protrusions of the warped material may collide with or become stuck in the box track, preventing the material from entering the box smoothly. This interference not only increases the failure rate in the production process but may also damage the material, thus affecting product quality.

[0005] In summary, existing conveying devices, when handling warped materials, suffer from reduced contact area between the material and the support platform, as well as interference with the material box track, which severely impacts the efficiency and quality of semiconductor packaging production. Utility Model Content

[0011] An auxiliary pressure roller is disposed on the inner side of the track frame, near the material feeding end and above the first belt, and has a first gap between it and the support platform for the outer edge of the material to pass through.

[0012] A guiding mechanism, disposed opposite to the auxiliary pressure roller and the material box, includes a guiding block and a supporting block. The guiding block and the supporting block are disposed opposite to each other on the same track frame in a direction perpendicular to the material transport direction.

[0017] In one embodiment, the second drive mechanism is disposed on the track frame near the feeding end, and the push rod is located on the side of the support platform away from the material box.

Therefore, the illustrations only show the components related to this utility model and are not drawn according to the actual number, shape and size of the components in the actual implementation.

[0030] In the semiconductor packaging field, the transport of materials such as chips and circuit boards is a critical step in the production process. With the continuous advancement of semiconductor manufacturing technology, higher demands are being placed on the accuracy, stability, and safety of the transport of these materials.

[0031] However, existing conveying devices have several problems when handling warped materials. First, due to their irregular shape, the contact area between warped materials and the support platform is reduced, making normal conveying difficult and prone to slippage or deviation. Second, when warped materials enter the material box, they may interfere with the box track, preventing smooth entry and increasing the failure rate and downtime during production. Furthermore, the material surface is easily scratched when in contact with the conveyor push rod, affecting the surface quality of the material and consequently impacting product performance and reliability.

[0032] These problems not only severely impacted production efficiency but also led to a decline in product quality and increased production costs.

[0033] To address the above-mentioned shortcomings, this application provides a transmission device. The following embodiments will now be described in detail.

[0034] This embodiment provides a transmission device, such as... Figure 1 As shown, the conveying device includes a track frame 100, a belt conveyor assembly, a push rod conveyor assembly, an auxiliary pressure roller 400, and a guide mechanism 500.

[0035] The conveying device in this embodiment includes two track frames 100, which are arranged opposite to each other, and the material is transported in the space formed by the two track frames 100. Along the material transport direction, each track frame 100 includes a loading end and a unloading end, with the unloading end located near the material box. The material in this embodiment mainly refers to chips, circuit boards, etc., that exhibit warping; however, chips, circuit boards, etc., that do not exhibit warping can also be conveyed using the conveying device provided in this embodiment.

[0036] The belt conveyor assembly includes a first guide rail 210, a first belt, a first drive mechanism 220, and a support platform 230. Specifically, a first guide rail 210 is provided on the inner side of each track frame 100, and the direction of the first guide rail 210 is parallel to the material transport direction; a first belt (not shown in the figure) is arranged parallel above each first guide rail 210; the first drive mechanism 220 is disposed on the track frame 100 and is used to drive the first belt to reciprocate along the first guide rail 210; the first drive mechanism 220 can be a motor; a support platform 230 is fixedly connected above the two first belts, and the material is placed on the support platform 230 for transport.

[0037] The push rod conveying assembly includes a second guide rail 310, a push rod 320, a second drive mechanism 330, and a second belt (not shown in the figure). The second guide rail 310 is located on the outer side of one of the track frames 100, and is parallel to the material transport direction. The second drive mechanism 330 is mounted on the track frame 100 and connected to the push rod 320 via the second belt to drive the push rod 320 to move along the second guide rail 310. The push rod 320 then moves the material placed on the support platform 230. The second drive mechanism 330 can be a motor.

[0038] Auxiliary pressure rollers 400 are symmetrically arranged on the inner side of the two track frames 100. The auxiliary pressure rollers 400 are located near the unloading end of the track frame 100 and above the first belt. Figure 1 The first belt is not shown; therefore, the auxiliary pressure roller 100 is shown above the first guide rail 210. A first gap exists between the auxiliary pressure roller 400 and the support platform 230, allowing the outer edge of the material to pass through. The vertical height of the first gap is less than the warp height of the material, thus allowing for compression and gentle downward pressure. This increases the contact area between the material and the support platform 230, enhancing friction and eliminating slippage, deviation, or stagnation of warped material during conveying, thereby improving the stability and accuracy of the conveying process.

[0039] Both track frames 100 have a guide mechanism 500 at their ends (i.e., the unloading end). The guide mechanism 500 is located between the auxiliary pressure roller 400 and the material box. Each guide mechanism 500 includes a guide block 510 and a bearing block 520, along a direction perpendicular to the material transport direction (i.e., Figure 1In the vertical direction of the material box, the guide block 510 and the support block 520 are arranged opposite each other, and there is a second gap between the guide block 510 and the support block 520 for the outer edge of the material to pass through. The vertical height of the second gap is less than the warp height of the material, which can also squeeze the material, increase the contact area between the material and the support table 230 and enhance the friction between the material and the support table 230. In addition, since the guide mechanism 500 is arranged adjacent to the material box, the squeezing of the material by the guide mechanism 500 also helps to guide the material smoothly into the track inside the material box, solving problems such as poor conveying, jamming, and interference with the material box track.

[0040] The conveying device provided in this embodiment, by setting an auxiliary pressure roller 400 and a guiding mechanism 500, can effectively press the material onto the support platform 230, significantly increasing the contact area between the material and the support platform 230. This greatly enhances the friction between the material and the support platform 230, ensuring that the material can move stably and smoothly during the conveying process. It avoids slippage, deviation, or stagnation caused by insufficient contact area, significantly improving the reliability and stability of the conveying. The guiding mechanism 500 can also precisely guide the material to smoothly enter the material box, effectively solving the problem of interference between warped material and the material box track in the prior art. It can ensure that the material avoids collision or jamming with the material box track when entering the material box, reducing the failure rate in the production process and improving production efficiency.

[0041] In an optional embodiment, the auxiliary pressure roller 400 is connected to a drive spring disposed within the track frame 100. The auxiliary pressure roller 400 has a passive lifting function, which can be achieved by the drive spring. Specifically, a groove and a through hole are formed on the track frame 100, with the through hole communicating with the groove. The drive spring is disposed within the groove, with one end of the drive spring fixedly connected to the top or bottom of the groove, and the other end of the drive spring being a free end. A connector is disposed on the free end, and the connector passes through the through hole and connects to the auxiliary pressure roller 400. To ensure a straight path of movement for the drive spring, a guide rail can be disposed within the drive spring, allowing the drive spring to lift and lower along the guide rail. Thus, the first gap formed between the auxiliary pressure roller 400 and the support platform 230 can accommodate warped materials of different thicknesses, and the conveying device provided in this embodiment has universality.

[0042] In an optional embodiment, the vertical height of the first gap is between 0.1 mm and 2 mm. The height of the first gap can fluctuate between 0.1 mm and 2 mm to accommodate warped materials of different thicknesses in the prior art. This embodiment does not specifically limit the vertical height of the first gap, as long as it can meet the requirements for warped materials of different thicknesses in the prior art.

[0043] In optional embodiments, such as Figure 2As shown, along the material transport direction, the length of the guide block 510 is greater than the length of the support block 520. Part of the guide block 510 is located above the first guide rail 210. The lower surface of the guide block 510 located above the first guide rail 210 has a first ramp 511, that is, the lower surface of the first guide rail 210 near the auxiliary pressure roller 400 has a first ramp 511. Along the material transport direction, the vertical distance from the first ramp 511 to the upper surface of the first guide rail 210 gradually decreases. That is, the guide block 510 and the support platform 230 form a gradually narrowing channel (such as a funnel or horn shape) through the first ramp 511, which can prevent the warped material edge from hitting the side wall instantly. In the contraction section of the first ramp 511, it is gradually corrected to the center line by multi-stage guide surfaces. In this way, efficient and stable transmission can be achieved through gradual force application and dynamic correction.

[0044] In an optional embodiment, the angle between the first ramp 511 and the horizontal plane is not less than 15°. The inclined guide surface of the first ramp 511 decomposes the lateral extrusion force into normal pressure and axial propulsion force, which can reduce local pressure and avoid surface scratches or coating peeling of the warped material; at the same time, the tapered structure of the first ramp 511 increases the contact time with the warped material, reduces the instantaneous speed of the warped material entering the material box, and prevents the warped material from impacting the inner wall of the material box.

[0045] In optional embodiments, such as Figure 1 As shown, the second drive mechanism 330 is located at the loading end of the track frame 100, and the push rod 320 is located on the side of the support platform 230 away from the material box. In the prior art, the second drive mechanism 330 is located in the middle of the track frame 100. In the conveying device of this embodiment, the second drive mechanism 330 is moved to the loading end position. The position of the second drive mechanism 330 in this embodiment can avoid contact with the warped material, reducing the risk of scratches and abrasions to the warped material. In the prior art, the push rod 320 is located in front of the support platform 230. In this embodiment, the push rod 320 is located behind the support platform 230, which can avoid contact between the push rod 320 and the surface of the warped material, reducing the risk of scratches and abrasions to the warped material.

[0046] In an optional embodiment, the upper surface of the support block 520 is flush with the lower surface of the track in the material box, which effectively prevents the height difference between the warped material and the material box, and helps to solve problems such as uneven conveying of warped materials and jamming.

[0047] In optional embodiments, such as Figure 2 As shown, the conveying device in this embodiment includes at least two sets of auxiliary pressure rollers 400. Each set of auxiliary pressure rollers 400 includes two auxiliary pressure rollers 400 that are disposed opposite to each other inside the track frame 100, which further improves the stability and reliability of warped materials during the conveying process.

[0048] In optional embodiments, such as Figure 2As shown, a second ramp 521 is provided on the upper surface of the end of the support block 520 away from the material box, that is, the second ramp 521 is provided on the upper surface of the end of the support block 520 near the auxiliary pressure roller 400. Along the material transport direction, the vertical distance from the second ramp 521 to the lower surface of the guide block 510 gradually decreases, that is, the upper surface of the support block 520 and the guide block 510 at the point where they begin to overlap is provided with the second ramp 510, and the point where they begin to overlap forms a gradually narrowing channel (such as a funnel or horn shape), which can further improve the stability and reliability of warped materials during transport.

[0049] In an optional embodiment, the angle between the second ramp 521 and the horizontal plane is not less than 5°. The inclined guide surface of the second ramp 521 decomposes the lateral extrusion force into normal pressure and axial propulsion force, which can reduce local pressure and avoid surface scratches or coating peeling of the warped material; at the same time, the tapered structure of the second ramp 521 increases the contact time with the warped material, reduces the instantaneous speed of the warped material entering the material box, and prevents the warped material from impacting the inner wall of the material box.

[0050] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
