Abstract
Description
Technical Field
[0001] This application relates to the field of semiconductor manufacturing auxiliary fixture technology, and in particular to an auxiliary flipping fixture. Background Technology
[0002] With the development of modern electronic manufacturing technology and the increasing demands on consumer electronics products, electronic product manufacturing processes are becoming increasingly advanced. Semiconductor manufacturers need to continuously upgrade and transform their processes to meet market and customer requirements. In the assembly process of mobile phone camera modules, which includes surface mount technology (SMT), chip mounting, wire bonding, filter mounting, and lens loading, in addition to the original components, jigs and fixtures are also indispensable. Starting from the raw ceramic substrate, the product undergoes transportation, mounting, and soldering operations using various jigs and fixtures. Therefore, it is inevitable that the product will need to be transferred between trays during production to complete the requirements of the next workstation.
[0003] In related technologies, after the substrate completes surface mount technology (SMT), it undergoes process point mounting (PNP) and is transferred to another tray. If flipping is required, the product is manually flipped using tweezers. However, manually handling the product significantly reduces efficiency and can easily cause material to fall out during the process, resulting in poor product appearance and affecting the quality of the finished product.

The carrier plate is provided with a mounting groove communicating with the first acupoint. The clamping member is movably disposed on the mounting groove of the carrier plate to press against the product to be processed.
[0016] In one possible implementation, the fixing component includes a spring and a pin.

[0021] The technical solutions provided in this application have the following advantages compared with the prior art:
[0022] This application provides an auxiliary flipping fixture. Initially, the product to be processed is placed in the first cavity of a carrier plate. After the product (e.g., a substrate) is flipped to the second cavity of a flipping tray, it can proceed to the next processing step. In use, the first positioning post of the flipping tray is aligned with the first positioning hole of the carrier plate and then engaged, or the second positioning hole of the flipping tray is aligned with the second positioning post of the carrier plate and then engaged, so that the flipping tray and the carrier plate are engaged vertically. In the engaged state, the side of the flipping tray facing the carrier plate is in contact with the side of the carrier plate facing the flipping tray. Then, both are flipped simultaneously. At this time, the product to be processed falls from the first cavity into the second cavity, completing the flipping operation, so that subsequent PNP (Production Partitioning) operations can be performed. During the flipping process, because the side of the flipping tray facing the carrier plate is in contact with the side of the carrier plate facing the flipping tray, and the shape of the second cavity matches the shape of the product to be processed, the product can fall into the second cavity without misalignment. This not only improves efficiency but also prevents the product to be processed from falling and affecting its appearance, thereby ensuring the quality of the finished product.

[0037] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0038] The following disclosure provides numerous different embodiments or examples for implementing various structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.
[0039] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.
[0040] In existing technologies, after the substrate completes surface mount technology (SMT), it is first processed by PNP (Product Placement) and transferred to another tray. If flipping is required, the product is then manually flipped using tweezers. However, manually handling the product greatly affects efficiency, and it is also easy for material to fall out during the handling process, resulting in poor product appearance and affecting the quality of the finished product.
[0041] To address the technical problem that existing manual clamping products are prone to material loss during flipping, resulting in poor product appearance and affecting the quality of finished products, this application provides an auxiliary flipping fixture. By engaging the flipping tray with the carrier plate, the products to be processed can be flipped in batches, which can improve efficiency and prevent the products to be processed from falling and affecting their appearance, thereby ensuring the quality of finished products.
[0042] like Figures 1 to 3 As shown in the figure, this application embodiment provides an auxiliary flipping fixture, which includes a carrier plate 1 and a flipping tray 2. The carrier plate 1 is provided with a first acupoint 11 for accommodating the product to be processed. The flipping tray 2 is disposed above the carrier plate 1 and is provided with a second acupoint 21 for accommodating the product to be processed. The carrier plate 1 is provided with a first positioning hole 12, and the flipping tray 2 is provided with a first positioning post 22 that engages with the first positioning hole 12. Through the engagement of the first positioning hole 12 and the first positioning post 22, the flipping tray 2 and the carrier plate 1 can be connected.
[0043] Of course, in some embodiments not shown in the figure, a second positioning hole can also be provided on the flip tray 2, and a second positioning post can be provided on the carrier plate 1 to engage with the second positioning hole. The flip tray 2 and the carrier plate 1 can also be connected by engaging the second positioning hole and the second positioning post.
[0044] Initially, the product to be processed is placed in the first cavity 11 of the carrier plate 1. After the product (e.g., a substrate) is flipped to the second cavity 21 of the flip tray 2, it can proceed to the next processing step. In use, such as... Figure 4 As shown, firstly, the first positioning post 22 of the flipping tray 2 is aligned with the first positioning hole 12 of the carrier plate 1 and then engaged, or the second positioning hole of the flipping tray 2 is aligned with the second positioning post of the carrier plate 1 and then engaged, so that the flipping tray 2 and the carrier plate 1 are engaged vertically. In the engaged state, the side of the flipping tray 2 facing the carrier plate 1 is in contact with the side of the carrier plate 1 facing the flipping tray 2. Then, the two in the engaged state are flipped simultaneously. At this time, the product to be processed falls from the first cavity 11 into the second cavity 21, completing the flipping operation, so as to facilitate the subsequent PNP operation. During the flipping process, because the side of the flipping tray 2 facing the carrier plate 1 is in contact with the side of the carrier plate 1 facing the flipping tray 2, the shape of the second cavity 21 is adapted to the shape of the product to be processed, and the product to be processed can fall into the second cavity 21 without misalignment. In this way, not only can efficiency be improved, but the product to be processed can also be prevented from falling and affecting the appearance, thereby ensuring the quality of the finished product.
[0045] Alternatively, the flipping tray 2 can be made of thermoplastic material, such as polystyrene (PS), which is less expensive and less prone to deformation, and can meet the requirements of long-term transit use.
[0046] In some embodiments, the first acupoint 11 has a first unilateral tolerance with respect to the product to be processed, and the second acupoint 21 has a second unilateral tolerance with respect to the product to be processed. The first unilateral tolerance is smaller than the second unilateral tolerance. For example, the unilateral tolerance between the first acupoint 11 of the carrier plate 1 and the substrate can be set to 0.072 mm, and the unilateral tolerance between the second acupoint 21 of the flipping tray 2 and the substrate can be set to 0.15 mm. This setting can increase the success rate of flipping the product to be processed.
[0047] In some embodiments, such as Figure 2 and Figure 3 As shown, there are multiple first positioning holes 12, with at least two first positioning holes 12 respectively located at both ends of the carrier plate 1. There are multiple first positioning posts 22, with each of the multiple first positioning posts 22 corresponding to one of the multiple first positioning holes 12.
[0048] For example, the carrier plate 1 is provided with at least one first positioning hole 12 at each end of its length direction, and the flipping tray 2 is provided with at least one first positioning post 22 at each end of its length direction. This arrangement can improve the tightness of the engagement between the flipping tray 2 and the carrier plate 1, thereby improving the success rate of flipping the product to be processed.
[0049] For example, it can also be configured such that: the carrier plate 1 is provided with at least one first positioning hole 12 at each end of its width direction, and the flip tray 2 is provided with at least one first positioning post 22 at each end of its width direction, which can also improve the tightness of the engagement between the flip tray 2 and the carrier plate 1.
[0050] In some embodiments not shown in the figures, multiple second positioning holes are provided, with at least two second positioning holes respectively located at both ends of the flip tray 2, and multiple second positioning posts are provided, with each of the multiple second positioning posts corresponding to one of the multiple second positioning holes.
[0051] For example, the flipping tray 2 is provided with at least one second positioning hole at each end of its length direction, and the carrier plate 1 is provided with at least one second positioning post at each end of its length direction. This arrangement can improve the tightness of the engagement between the flipping tray 2 and the carrier plate 1, thereby improving the success rate of flipping the product to be processed.
[0052] For example, it can also be configured such that: the flip tray 2 is provided with at least one second positioning hole at each end of its width direction, and the carrier plate 1 is provided with at least one second positioning post at each end of its width direction, which can also improve the tightness of the engagement between the flip tray 2 and the carrier plate 1.
[0053] Of course, the above embodiments can also be used in combination.
[0054] In some embodiments, such as Figure 3 As shown, at least two of the first positioning holes 12 have different shapes. For example, as Figure 2 and Figure 3 As shown, one of the first positioning holes 12 is square, and the first positioning post 22 that engages with the first positioning hole 12 is rectangular; the other first positioning hole 12 is circular, and the first positioning post 22 that engages with the first positioning hole 12 is cylindrical. This arrangement can improve the positioning accuracy of the flipping tray 2 and the carrier plate 1. Of course, the first positioning hole 12 can also be set to other shapes, which will not be elaborated here.
[0055] In some embodiments, at least two second positioning holes have different shapes. For example, one second positioning hole is triangular, and the second positioning post that engages with the second positioning hole is triangular; the other second positioning hole is rhomboid, and the second positioning post that engages with the second positioning hole is prismatic. Of course, the second positioning holes can also be configured with other shapes, which will not be elaborated here.
[0056] In some embodiments, such as Figure 5 and Figure 6 As shown, the second acupoint 21 has a guide slope 211. (As indicated...) Figure 6 As shown, due to the presence of the guide slope 211, the cross-section of the second acupoint 21 gradually increases from top to bottom. During the flipping process, it plays a guiding role for the product to be processed, allowing the product to fall smoothly into the second acupoint 21.
[0057] In some embodiments, such as Figure 7 and Figure 8 As shown, a fixing assembly 13 for fixing the product to be processed is provided on the carrier plate 1. The fixing assembly 13 includes a clamping member 131. The carrier plate 1 is provided with a mounting groove 14 communicating with the first acupoint 11. The clamping member 131 is movably disposed on the mounting groove 14 of the carrier plate 1 to hold the product to be processed. Initially, the product to be processed is placed in the first acupoint 11 of the carrier plate 1. The clamping member 131 can hold the product to be processed and provide clamping force to the product to be processed, thereby fixing it. When it is necessary to flip it, the clamping member 131 moves away from the product to be processed relative to the carrier plate 1, so that the product to be processed can fall smoothly into the second acupoint 21 of the flipping tray 2.
[0058] Optionally, the clamping member 131 may be flat or block-shaped.
[0059] Furthermore, such as Figure 7 and Figure 8As shown, the fixing component 13 includes a spring 132 and a pin. The spring 132 is embedded in the mounting groove 14. One end of the spring 132 is connected to the carrier plate 1, and the other end of the spring 132 is connected to the clamping member 131. The clamping member 131 is provided with a first pin hole, and the carrier plate 1 is provided with a second pin hole corresponding to the first pin hole. The clamping member 131 is connected to the carrier plate 1 through the pin. Initially, the product to be processed is placed in the first cavity 11 of the carrier plate 1. The spring 132 is in a stretched state. One end of the pin passes through the first pin and the second pin in sequence and is engaged with the carrier plate 1, so that the clamping member 131 will not move relative to the carrier plate 1 under the elastic action of the spring 132. When flipping is required, the pin is removed, and the clamping part 131 moves away from the product to be processed relative to the carrier plate 1 under the restoring force of the spring 132. The clamping part 131 will not provide clamping force to the product to be processed. After flipping, the product to be processed can fall smoothly into the second acupoint 21 of the flipping tray 2 under its own gravity.
[0060] In some embodiments, such as Figure 3 As shown, the carrier plate 1 is provided with a first handle position 15. Specifically, a first groove may be provided on the side of the carrier plate 1 facing the flip tray 2 to form the first handle position 15 for convenient operation.
[0061] In some embodiments, such as Figure 2 As shown, the flip tray 2 is provided with a second handle position 23. Specifically, the flip tray 2 may be provided with a second groove to form the second handle position 23. There may be two second grooves, which are respectively provided at both ends of the flip tray 2 for convenient operation.
[0062] In some embodiments, such as Figure 1 and Figure 2 As shown, the flipping tray 2 is provided with reinforcing ribs 24. The orthographic projection of the reinforcing ribs 24 on the horizontal plane does not intersect with the orthographic projection of the second acupoint 21 on the horizontal plane. Multiple reinforcing ribs 24 can be provided, and the multiple reinforcing ribs 24 are crisscrossed to enhance the structural strength of the flipping tray 2. The orthographic projection of the reinforcing ribs 24 on the horizontal plane does not intersect with the orthographic projection of the second acupoint 21 on the horizontal plane to avoid affecting the normal falling of the product to be processed.
[0063] In some embodiments, multiple first acupoints 11 are provided, and the multiple first acupoints 11 are spaced apart; multiple second acupoints 21 are provided, and the multiple second acupoints 21 correspond one-to-one with the multiple first acupoints 11. With multiple first acupoints 11, multiple products to be processed can be flipped and fall into the multiple second acupoints 21 of the flipping tray 2 at the same time, thereby further improving efficiency.
