Description

Technical Field

[0001] This utility model relates to the field of packaging equipment technology, and specifically to auxiliary equipment for semiconductor chip packaging. Background Technology

[0002] In the field of semiconductor chip packaging, efficient and stable transport of chip carriers is a key factor in ensuring packaging quality and production capacity. Traditional transport equipment mostly adopts single-station propulsion or asynchronous transport modes. The sequential transport of single carriers results in long production line cycle times, which is difficult to match the requirements of high-speed packaging processes. Carriers are susceptible to displacement due to vibration during transport, especially when multiple carriers are transported in parallel, resulting in poor synchronization and increasing the risk of chip position errors. To address this, we propose auxiliary equipment based on semiconductor chip packaging. Utility Model Content

[0003] In view of the shortcomings of the prior art, this utility model provides an auxiliary device for semiconductor chip packaging to solve the problems existing in the prior art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] An auxiliary device for semiconductor chip packaging includes a frame and a slide rail mounted on a crossbeam of the frame, characterized in that:

[0006] It also includes a conveying unit, which contains:

[0007] A linear slide fixed to the longitudinal beam of the frame;

[0008] Guide rails fixed to the upper crossbeam;

[0009] The sliding rod is connected to the moving platform of the linear slide table through the connecting plate, and slides with the slider of the guide rail through the fixed plate;

[0010] The linear slide table drives the sliding rod to move back and forth along the guide rail.

[0011] Preferably, multiple push plates are vertically fixed on the sliding rod at intervals to form a workstation interval that adapts to the chip carrier board;

[0012] As the sliding rod moves, it simultaneously pushes multiple chip carrier boards along the slide rail via a push plate.

[0013] Preferably, the top surface of the sliding rod is flush with the sliding rail, together forming a stepless composite support surface for the carrier plate.

[0014] Preferably, the push plate is detachably fixed to the sliding rod by locking bolts, and the distance between the push plates is adjustable.

[0015] Preferably, the connecting plates are two symmetrically arranged pieces, fixed to both sides of the end of the sliding rod, and a clearance space is formed between the two connecting plates to accommodate the cross section of the guide rail.

[0016] Preferably, it also includes a limiting unit, which comprises:

[0017] A rotating rod, parallel to the slide rail, is mounted on the side of the frame via a mounting bracket;

[0018] Gears fixed to the rotating rod and racks meshing with them;

[0019] Limiting plates connecting each rack;

[0020] The electric push rod drives the rotating rod to rotate via a crank, causing the limit plate to dynamically abut against the side of the carrier plate.

[0021] This invention provides auxiliary equipment for semiconductor chip packaging. It has the following advantages:

[0022] 1. By sliding the sliding rod and the guide rail, and actively driving the sliding rod with the linear slide table, combined with the station interval formed by the spaced push plates, the synchronous and stable transport of multiple chip carrier boards is achieved, which significantly improves the packaging efficiency. At the same time, the design of the sliding rod height being flush with the guide rail ensures that the carrier board moves without bumps on the composite support surface, reducing the risk of chip displacement.

[0023] 2. The limiting unit adopts a gear-rack transmission and electric push rod linkage design. The synchronous controller drives the limiting plate to dynamically move closer to the side of the carrier plate, which can offset the lateral separation force in real time, making it especially suitable for high-speed conveying scenarios. The symmetrical crank layout ensures balanced force transmission and avoids damage to the carrier plate due to pressure on one side. Attached Figure Description

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, what is described is only a part of this utility model, not all of it. Based on this utility model, all other inventions obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0030] See attached document Figure 1-4 The auxiliary equipment for semiconductor chip packaging includes a frame 1 and a slide rail 2 that is installed parallel to the upper crossbeam 11 of the frame 1 to allow the chip carrier to slide. A pair of lower crossbeams 12 that are parallel to the upper crossbeam 11 are also connected to the column of the frame 1. A longitudinal beam 13 is also connected between the lower crossbeams 12. The longitudinal beam 13 is in the same direction as the slide rail 2.

[0031] It also includes a conveying unit 4 disposed between slide rails 2 and arranged along the direction of slide rails 2. The conveying unit 4 includes a sliding rod 43, a guide rail 42, and a linear slide table 41 arranged from top to bottom and parallel to each other. The linear slide table 41 is fixedly installed on the longitudinal beam 13, and the guide rail 42 is fixedly installed on the upper cross beam 11. The sliding rod 43 is connected to the slider of the guide rail 42 through a fixing plate 45, so that the sliding rod 43 can slide along the direction of the guide rail 42. One end of the sliding rod 43 is connected and fixed to the moving platform of the linear slide table 41 through a connecting plate 44. The linear slide table 41 is used to drive its moving platform, and then drives the sliding rod 43 to slide along the direction of the guide rail 42 through the connecting plate 44.

[0032] It should be noted that there are two connecting plates 44, which are fixedly installed on both sides of the end of the sliding rod 43. A space is formed between the two connecting plates 44. The size of this space is designed to accommodate the cross section of the guide rail 42. When the sliding rod 43 is driven to slide by the linear slide table 41, the guide rail 42 fixed on the upper crossbeam 11 can pass through the space between the two connecting plates 44, thereby avoiding motion interference.

[0033] Several push plates 46 perpendicular to the sliding rod 43 are fixedly arranged at intervals along its length. The push plates 46 divide the sliding rod 43 into multiple workstation intervals that are adapted to the chip carrier. The chip carrier can be placed in the interval between adjacent push plates 46. The push plates 46 are used to accommodate and separate the chip carrier, and can also push the chip carrier when the sliding rod 43 moves, transferring the chip carrier to the next process.

[0034] When the chip carrier slides on the slide rail 2 and the sliding rod 43, there is a risk that the chip carrier will detach from the support surface due to the lack of side shielding. To address this, a limiting unit 3 is provided on the frame 1. The limiting unit 3 includes several mounting seats 35 that are parallel to the slide rail 2 and located on the side of the frame 1. The mounting seats 35 are connected by bearings to the same rotating rod 34. A gear 36 is fixedly sleeved on the rotating rod 34 located in the mounting seat 35. The gear 36 is meshed with a rack 37 that is linearly slidable in the mounting seat 35. The multiple racks 37 are connected by the same limiting plate 38 to abut against the chip carrier.

[0035] It also includes a mounting bracket 31 installed on the longitudinal beam 13. A pair of opposing electric push rods 32 are hinged on the mounting bracket 31. The output end of the electric push rod 32 is hinged to a crank 33 fixedly installed on the rotating rod 34. The electric push rods 32 are simultaneously pushed out by a synchronous controller. That is, the crank 33 drives the rotating rod 34 to rotate on the mounting base 35. The gear 36 on the rotating rod 34 meshes with the rack 37 in the mounting base 35. Under the rotation drive of the rotating rod 34, the rack 37 can be driven to move closer to the side of the chip carrier, so that the limiting plate 38 abuts against the side of the chip carrier, preventing the chip carrier from laterally separating from the support surface composed of the slide rail 2 and the sliding rod 43 during the transportation process.

[0036] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0037] The above description is only used to illustrate the technical solutions of this utility model, and is not intended to limit it. Although the utility model has been described in detail with reference to the foregoing, those skilled in the art should understand that modifications can still be made to the foregoing technical solutions, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the various technical solutions of this utility model.
