Description

Technical Field

[0001] This utility model belongs to the field of chip processing technology, specifically relating to a chip board feeding device and a support mechanism. Background Technology

[0002] Ultrasonic thermoforming welding machines are high-precision devices specifically designed for semiconductor back-end processes (packaging). These machines combine heating, pressure, and ultrasonic vibration to achieve the welding of metal leads.

[0003] In the "heating" process, the equipment's worktable (heating block) preheats the components to be soldered (such as diode chips and leads fixed on a chip board) to a lower temperature (usually much lower than the soldering temperature, such as 200-300°C). This makes the material on the chip board easier to deform and helps to eliminate moisture and oxide layers on the material surface.

[0004] In actual use, depending on the different products produced (diodes, LEDs, etc.), the chip board will carry corresponding base islands and tube corners in an array. Since the shape and size of each component are different, the overall length of the chip board produced will also vary. Therefore, in order to better preheat the chip board, a heating block of the same size as the chip board will be used. Due to the limitations of the equipment structure layout, there is always a certain gap between the chip box and the heating block. This causes the chip board to deform and dent due to gravity during the process of being pushed from the chip box to the top of the heating block. Ultimately, the dented part of the chip board will hit the side wall of the heating block, making the chip board unusable.

[0005] Therefore, a chip board feeding device and a supporting mechanism are designed to solve the technical problem in the prior art where the chip board deforms due to gravity during the process of moving above the heating block, and its front end makes a rigid impact with the side wall of the heating block, resulting in damage to precision components or circuit breakage on the chip board and rendering it unusable.

[0006] It should be noted that the information disclosed in this background section is only for understanding the background technology of the present application concept, and therefore, the above description is not considered to constitute prior art information. Utility Model Content

The chip board is disposed on the upper surface of the lifting plate.

[0013] In one alternative implementation, the actuating component includes: A push cylinder is located on one side of the chip box; and The T-shaped push rod has its vertical end connected to the output end of the push cylinder, and the side wall of the horizontal end of the T-shaped push rod is adapted to abut against the side wall of the chip board.

[0014] In one optional embodiment, the chip box has a through-hole on its end face facing the feed table; The inner wall of the feeding platform is symmetrically provided with sliding grooves; wherein The length of the through opening is equal to the distance between the two grooves; and The distance between the two grooves is greater than the width of the chip board.

Furthermore, in the accompanying drawings, the thickness of the components may be exaggerated or reduced for the purpose of effectively describing the technical content.

[0026] In this document, when an element or layer is referred to as “located,” “joined to,” “connected to,” “attached to,” or “coupled to” another element or layer, it may be directly located, joined, connected, attached to, or coupled to the other element or layer, or there may be intermediate elements or layers present. Conversely, when an element is referred to as “directly on another element or layer,” “directly joined to,” “directly connected to,” “directly attached to,” or “directly coupled to” another element or layer, there may be no intermediate elements or layers present. Other terms used to describe relationships between elements should be interpreted in a similar manner (e.g., “between” versus “directly between,” “adjacent” versus “directly adjacent,” etc.). As used herein, the term “and / or” includes any and all combinations of one or more of the related listed items.

[0027] In this document, exemplary embodiments of the present disclosure will be described in more detail with reference to the accompanying drawings. As used herein, expressions such as “at least one of…” modify the entire list of elements when following a list of elements, rather than individual elements in the list. For example, the expression “at least one of a, b, and c” should be understood to include only a, only b, only c, both a and b, both a and c, both b and c, or all of a, b, and c.

[0028] The terminology used herein is for the purpose of describing specific exemplary configurations only and is not intended to be limiting. As used herein, the singular articles “a,” “an,” and “the” may also be intended to include plural forms unless otherwise clearly stated herein. The terms “comprising,” “including,” and “having” are inclusive and thus specify the presence of features, steps, operations, elements, and / or components, but do not preclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof.

Therefore, a particular feature, structure, or characteristic can be included in more than one embodiment of this disclosure, such that these phrases do not necessarily refer to the same embodiment. As used herein, the terms “example,” “exemplary,” etc., are used to “serve as an example, instance, or illustration.” Any implementation, aspect, or design described herein as “example” or “exemplary” is not necessarily to be construed as preferred or superior to other implementations, aspects, or designs.

[0030] Research has revealed that in actual use, depending on the different products being manufactured (diodes, LEDs, etc.), the chip board will array and support corresponding base islands and tube corners. Due to the different shapes and sizes of the components, the overall length of the produced chip board will also vary. Therefore, in order to better preheat the chip board, a heating block of the same size as the chip board will be used. Due to the installation requirements of the overall equipment, there is always a certain gap between the chip box and the heating block. This causes the chip board to dent due to the lack of support below it when it is pushed from the chip box to the top of the heating block. Ultimately, the dented part of the chip board will hit the side wall of the heating block, rendering the chip board unusable.

[0031] Based on the above research, this disclosure provides a chip board feeding device and a support mechanism. By providing a support mechanism, multiple support plates in the support mechanism are placed between the chip box and the heating block. When the chip board is pushed towards the heating block, the multiple support plates support the lower end face of the chip board, preventing the chip board from denting due to lack of support during movement and ultimately hitting the side wall of the heating block, thus causing the chip board to be scrapped.

[0032] The shortcomings of the above solutions are the result of the inventor's practical experience and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure should be considered as the inventor's contribution to this disclosure.

[0033] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0034] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0035] In some embodiments, such as Figure 1 and Figure 2 As shown, before heating the chip board 5, the operator first places the chip box 2 on one side of the feeding table 1. Several chip boards 5 are placed in the chip box 2 (only one is shown in the figure). After the chip box 2 is in place, the lifting cylinder 400 is activated. Its output end drives the lifting rod 401 and the lifting plate 402 fixed to the upper end of the lifting rod 401 to move upward. This lifts the chip board 5 at the top of the chip boards 5 placed on the lifting plate 402 to align with the through hole 20. Then, the pushing cylinder 410 is activated. Its output end drives the T-shaped push rod 411 to extend. The horizontal side wall of the T-shaped push rod 411 abuts against the side wall of the top chip board 5, thereby pushing the top chip board 5 to slide out of the through hole 20. As the T-shaped push rod 411 continues to extend, the two long sides of the chip board 5 slide into the two symmetrically opened sliding grooves 11 in the feeding table 1 until the chip board 5 slides directly above the heating block 10.

[0036] In some embodiments, such as Figure 2 and Figure 3 As shown, when the chip board 5 is pushed out of the through-hole 20, the lower end face of the chip board 5 abuts against the upper end face of the multi-section support plate 33. The multi-section support plate 33 fills the gap between the chip box 2 and the heating block 10, preventing the lower end face of the chip board 5 from sinking due to lack of support during the movement. During the installation process, the height of the right inclined plate 331 in the multi-section support plate 33 is slightly higher than the upper end face of the heating block 10 so that the chip board 5 falls on the upper end face of the heating block 10.

[0037] In some embodiments, such as Figure 3 and Figure 4 As shown, when the size of the chip board 5 is changed, the heating block 10 that matches the chip board 5 is replaced simultaneously. Therefore, the distance between the heating block 10 and the chip box 2 will change. When the distance between the two increases, after the chip board 5 moves out of the through-hole 20, the rotary motor 30 is started. Its output end drives the lead screw 32 to rotate. The upper end face of the moving plate 34 is fixed to the right inclined plate 331, and the moving plate 34 is threadedly engaged with the lead screw 32. Therefore, during the rotation of the lead screw 32, the moving plate 34 and the right inclined plate 331 will be driven to move along the axis of the lead screw 32. During this process, the left inclined plate 330 and one of the fixed plates 31 remain stationary. As the right inclined plate 331 moves away from the left inclined plate 330, the slide bar 333 will slide out from between the corresponding driven plates 332 along the F1 direction (as shown). Figure 4 (as shown in the diagram), that is, the length of the multi-section carrier plate 33 is increased to accommodate the spacing between the chip box 2 and the heating block 10.

[0038] In the description of the embodiments of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0039] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence unless expressly indicated herein. Therefore, without departing from the teachings of the exemplary embodiments, the first element, component, region, layer, or segment discussed above may be referred to as the second element, component, region, layer, or segment.

[0040] Spatially relative terms, such as “inside,” “outside,” “below,” “below,” “down,” “above,” “up,” etc., may be used herein to describe the relationship between one element or feature illustrated in the figures and another element or feature. In addition to the orientations depicted in the figures, spatially relative terms may be intended to cover different orientations of the device in use or operation. For example, if the device in the figure is flipped, an element described as “below” or “below” other elements or features would be oriented as “above” other elements or features. Thus, the example term “below” can cover both above and below orientations. The device may be oriented in other ways (rotated 90 degrees or in other orientations), and the spatially relative descriptors used herein are interpreted accordingly.

[0041] In the above discussion, unless otherwise stated, when used to describe numerical values, the terms “about,” “approximately,” “basically,” etc., indicate a change of + / - 10% in that value.

[0042] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
