Abstract
Description
Technical Field
[0001] This utility model relates to a manually operated HD fixture, belonging to the field of optoelectronic processing technology. Background Technology
[0002] Fixtures can be divided into three categories: process assembly fixtures, project testing fixtures, and circuit board testing fixtures. In the optoelectronic technology process, process assembly fixtures are needed to place HDs. However, current HD fixtures are all placed manually, and the positioning of HDs on the HD fixtures is not accurate. This results in inconsistent HD positions when HDs are placed on the substrate manually, which makes the subsequent dispensing and bonding processes inaccurate in identifying the HD position and producing a large number of dispensing and bonding defects. Moreover, setting positioning components on each fixture can easily increase costs.
[0003] In this invention, HD refers to Hard Die, a bare chip made of hard and brittle materials such as sapphire, silicon, gallium arsenide, and lithium tantalate, used in the packaging and mounting process of optoelectronic components or electronic components. HD has a regular shape and requires precise positioning through grooves.
[0004] Therefore, in order to reduce costs while ensuring the effective placement of HD, a manual HD placement fixture is urgently needed. Utility Model Content
[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a manual HD placement fixture. By installing a detachable support plate on the main board and setting a positioning groove and an L-shaped positioning component on the main board for positioning, and setting a first HD placement area and a second HD placement area for placing HD on the support plate, the positioning and placement of HD can be performed on different components. That is, the positioning of HD on multiple support plates can be completed by a single main board, so as to reduce costs while ensuring effective placement of HD.
[0006] To achieve the above objectives / to solve the above technical problems, this utility model adopts the following technical solution:
[0007] A manual HD placement fixture includes a main board, a support plate, a first HD placement area, a second HD placement area, a positioning groove, and an L-shaped positioning assembly.
[0008] The support plate is detachably mounted on the motherboard. The first HD placement area and the second HD placement area are sequentially arranged on the support plate. Both the first HD placement area and the second HD placement area include several grooves for placing HD. The L-shaped positioning component is installed on the upper surface edge of the motherboard. The positioning groove is opened on the side of the motherboard where the L-shaped positioning component is not provided.
[0009] Furthermore, the L-shaped positioning component includes a horizontal limiting plate, a vertical limiting plate, and an origin groove. The horizontal limiting plate is fixed to the left edge of the upper surface of the motherboard, the vertical limiting plate is fixed to the top edge of the upper surface of the motherboard, and the origin groove is formed at the junction of the horizontal limiting plate and the vertical limiting plate.
[0010] Furthermore, it also includes positioning holes, which are formed on the motherboard, and positioning pins that are adapted to the positioning holes are fixed on the bottom side of the support plate.
[0011] Furthermore, it also includes mating grooves, which are formed on both sides of the top of the support plate, and mating posts are threaded onto the mating grooves.
[0012] Furthermore, the lower part of the mating post is provided with an external thread that matches the mating groove, and the upper part of the mating post is fixed with a lifting block.
[0013] Furthermore, the number of grooves in the first HD placement area is less than the number of grooves in the second HD placement area.
[0014] Furthermore, it also includes numbering slots, which are formed on the support plate.
[0015] Furthermore, the number of positioning holes is at least two.
[0016] Compared with the prior art, the beneficial effects achieved by this utility model are as follows:
[0017] The manual HD placement fixture provided by this utility model has a detachable support plate installed on the main board, and a positioning groove and an L-shaped positioning component for positioning are set on the main board. The support plate is provided with a first HD placement area and a second HD placement area for placing HD. This allows the positioning and placement of HD to be performed on different components. In other words, the positioning of HD on multiple support plates can be completed by one main board, so as to reduce costs while ensuring effective placement of HD.
[0018] The manual HD placement fixture provided by this utility model allows for the placement of HDs. After all the grooves on the current support plate have been placed, the mating column can be connected to the mating groove on the current support plate to move the support plate through the mating column. This allows for the replacement of the support plate with a new one that is not equipped with HDs, and the placement of the next batch of HDs can be carried out. Thus, the positioning of HDs on multiple support plates can be achieved through a single main board.
[0019] The manual HD jig provided by this utility model allows each support plate to be numbered by setting numbering slots on the support plate, which facilitates subsequent record management. Attached Figure Description

[0025] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.
[0026] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "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, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.
[0027] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" 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. Example 1
[0028] like Figure 1 As shown, this embodiment provides a manual HD placement fixture, including a main board 1, a support plate 2, a first HD placement area 3, a second HD placement area 4, a positioning groove 5, and an L-shaped positioning assembly.
[0029] The support plate 2 is detachably mounted on the motherboard 1. The first HD placement area 3 and the second HD placement area 4 are sequentially arranged on the support plate 2. The first HD placement area 3 and the second HD placement area 4 each include a plurality of grooves 6 for placing HD. The L-shaped positioning component is installed at the upper surface edge of the motherboard 1. The positioning groove 5 is opened on the side of the motherboard 1 where the L-shaped positioning component is not provided.
[0030] In the above technical solution, by installing a detachable support plate 2 on the motherboard 1, and setting a positioning groove 5 and an L-shaped positioning component on the motherboard 1 for positioning, and setting a first HD placement area 3 and a second HD placement area 4 for placing HD on the support plate 2, the positioning of HD and the placement of HD can be performed on different components. That is, the positioning of HD on multiple support plates 2 can be completed by one motherboard 1, so as to reduce costs while ensuring effective placement of HD.
[0031] The groove 6 is the same size as the HD to ensure the accuracy of the HD's positioning. The positioning slot 5 is located on the side of the motherboard 1 to assist in the installation and positioning of the motherboard 1 on the worktable. In most cases, the HD is placed manually using this manual HD placement fixture. When the production period is short and the efficiency of manual HD placement is insufficient, the efficiency of HD placement can be improved by using an L-shaped positioning component in conjunction with the relevant operating machine. The long and short shaft ends of the L-shaped positioning component can be used as the X and Y axes for auxiliary positioning. Thus, when the machine is working, the operator can set the intersection of the long and short shaft ends as the origin and program the machine so that the machine can accurately position the HD in the groove 6. Example 2
[0032] like Figures 1-4 As shown, the manual HD sizing fixture provided in this embodiment differs from the manual HD sizing fixture provided in Embodiment 1 in that:
[0033] like Figure 1 and Figure 2 As shown, to achieve auxiliary positioning of the L-shaped positioning component, the L-shaped positioning component includes a horizontal limiting plate 7, a vertical limiting plate 8, and an origin groove 9. The horizontal limiting plate 7 is fixed at the left edge of the upper surface of the main board 1, and the vertical limiting plate 8 is fixed at the top edge of the upper surface of the main board 1. The origin groove 9 is opened at the intersection of the horizontal limiting plate 7 and the vertical limiting plate 8. The horizontal limiting plate 7 and the vertical limiting plate 8 can serve as the X-axis and Y-axis in positioning, and the origin groove 9 serves as the origin. Thus, when the machine is working, the operator can program the machine after setting the intersection of the origin groove 9 as the origin so that the machine can accurately position the HD in the groove 6.
[0034] like Figure 2 and Figure 3 As shown, in order to achieve a detachable connection between the support plate 2 and the main board 1, a positioning hole 10 is also included. The positioning hole 10 is opened on the main board 1, and a positioning post 11 that matches the positioning hole 10 is fixed on the bottom side of the support plate 2.
[0035] like Figure 1 , Figure 3 and Figure 4 The diagram shows the movement of the support plate 2 after all HDs have been placed on it. It also includes a mating groove 12, which is located on both sides of the top of the support plate 2. A mating post 13 is threaded onto the mating groove 12. Moving the mating post 13 allows for rapid movement of the support plate 2. The threaded connection between the mating post 13 and the mating groove 12 allows the mating post 13 to be removed before placing the HDs to avoid interference. When the support plate 2 needs to be moved later, the mating post 13 can be reconnected to the mating groove 12.
[0036] like Figure 4 The diagram shows the connection between the mating groove 12 and the mating column 13. The lower part of the mating column 13 is provided with an external thread that matches the mating groove 12. The upper part of the mating column 13 is fixed with a lifting block 15. The cross-sectional area of the lifting block 15 is larger than the radial area of the mating column 13, which facilitates the movement of the support plate 2 through the mating column 13.
[0037] To facilitate partition management, such as Figure 1 As shown, the number of grooves 6 in the first HD placement area 3 is less than the number of grooves 6 in the second HD placement area 4. By having a first HD placement area 3 and a second HD placement area 4 with different numbers of grooves 6, the HDs can be divided into sections based on the number of grooves on the support plate 2, which facilitates subsequent management.
[0038] To number each support plate 2 for easy record management, a numbering slot 14 is also included, which is formed on the support plate 2, such as... Figure 1 As shown, the numbering slot 14 is located in the first HD placement area 3 and the second HD placement area 4. The numbering slot 14 can be installed in a magnetic or slot-type manner, which can be selected according to the actual situation.
[0039] To ensure stability when the support plate 2 is connected to the main board 1, the number of positioning holes 10 is at least two, such as... Figure 2 As shown, in this embodiment, there are two positioning holes 10, but it is not limited to this. When considering that two positioning holes 10 are not enough, more positioning holes 10 can be selected, and the number of positioning posts 11 can be adjusted accordingly.
[0040] In summary, the manual HD placement fixture provided in this embodiment allows for the placement of HDs. After all the grooves 6 on the current support plate 2 have been placed, the mating post 13 can be connected to the mating groove 12 on the current support plate 2. The support plate 2 can be moved by the mating post 13 to replace the support plate 2 without an HD, and the next batch of HDs can be placed. Thus, the positioning of HDs on multiple support plates 2 can be achieved through a single main board 1. By setting a numbering groove 14 on the support plate 2, each support plate 2 can be numbered for subsequent record management.
[0041] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
