Description

Package substrate feeding stage with positioning plate

This creation is a technical field of a feeding stage, and in particular refers to a design for carrying a package substrate in a semiconductor packaging process.

As shown in FIG. 1, it is a perspective view of a conventional feeding platform, which includes a base 11, a plurality of limit rods 12 and a linkage mechanism 13 located at the bottom of the base 11. The base 11 is provided with a plurality of moving grooves 111 in different directions, and the plurality of limit rods 12 stand upright in the corresponding moving grooves 111 and can move along the moving grooves 111. The position of the plurality of limiting rods 12 corresponds to the outline periphery of a package substrate A to limit the position of the package substrate A after stacking (only one piece is shown in the figure). The movement directions of the plurality of limit rods 12 include an X-axis and a Y-axis that are perpendicular to each other. The linkage mechanism 13 is located below the base 11 and is responsible for driving the multiple limit rods 12 to move synchronously, so that the enclosed area is synchronously enlarged or reduced. The sliding mode of the linkage mechanism is a common structure, so it will not be drawn and described. However, in this embodiment, in order to achieve synchronization and quickly drive multiple limit rods 12 to move, as shown in Figure 2, the linkage mechanism 13 is designed with two shafts on the same axis. There are two gears 131, 132 and four racks 133, 134, 135 and 136 meshing with the corresponding gears. The four racks 133~136 are respectively fixed to the corresponding sliders (not shown in the figure). The block is connected with the corresponding limit rod 12, and when the gears 131 and 132 rotate coaxially, the plurality of limit rods 12 in different directions are driven to move synchronously, so as to achieve the purpose of quickly adjusting and fixing the package substrate A.

However, after long-term use, due to the frequent reciprocating movement of the limit rod 12, the gear 131 and the rack 133, 134 and the gear 132 and the rack 135, 136 are prone to gaps, which easily cause the upper limit rod 12 to move distance Misalignment will cause the position of the package substrate A placed on the base 11 to deviate, causing the machine's sensor detector to fail to sense the height of the base 11 after being driven by a lifting base. After that, if the lifting base continues to rise, it will As a result, the base 11 hits other mechanisms and deforms, causing the package substrate A to be crushed or jammed.

In order to solve the above problems, the main purpose of this creation is to provide a packaging substrate feeding stage with a positioning plate, which mainly uses a positioning plate to limit the position of each positioning rod, and further ensure that each positioning rod is in the feeding process of the packaging process. Can not move arbitrarily to avoid accidents or failures, improve machine utilization, and increase profits relatively.

In order to achieve the foregoing objectives, this creation adopts the following technical solutions:

The conventional mechanism may cause the gears and racks to wear out, resulting in inaccurate meshing and easily shift the limit rods, but it may also be offset due to other factors, such as improper pushing of the limit rods during the process of placing the package substrate , But because of the use of the positioning plate in this creation, the correct position can be corrected, corrected and maintained immediately, which will eliminate the unfavorable factors and maintain the smooth operation; 3.

As shown in Figs. 3 and 4, it is a package substrate feeding stage with a positioning plate, which includes a base 2, a plurality of limit rods 3, and a positioning plate 4. The plurality of limit rods 3 are upright and movable, and the positions of the plurality of limit rods 3 can be moved to the periphery of the outline of the package substrate after being adjusted. The positioning plate 4 has a plurality of positioning holes 41. The enclosed area of the plurality of positioning holes 41 corresponds to the size of the package substrate. The number of positioning holes 41 corresponds to the number of the limit rods 3. When the positioning plate 4 is placed on the base 2, each limit The position rod 3 is located in the corresponding positioning hole 41, so as to ensure that the limit rod 3 will not deviate during subsequent packaging operations.

Then make a detailed description of the structure of each component:

The base 2 is used for stacking the packaging substrates on it, as a material for the subsequent packaging process. In actual operation, the base 2 is fixed on a lifting base (not shown in the figure), the base 2 is continuously raised by the lifting base, and then the uppermost package substrate is sequentially sucked by the suction member. In addition, in order to cooperate with the operation of the limit rod 3, the base 2 is provided with multiple moving grooves 21 in different directions. The multiple moving grooves 21 are arranged in the X-axis direction and the Y-axis direction. Four of the moving grooves 21 adopt the X-axis direction. Set, the other two moving grooves 2 are set in Y axis.

The multiple limiting rods 3 are used to limit the position of the package substrate placed on the base 2 to prevent the package substrate from shifting when the base 2 rises. Therefore, the plurality of limit rods 3 protrude from the base 2 from bottom to top, and the position of the plurality of limit rods 3 is on the periphery of the outline of the package substrate. The multiple limit rods 3 can move linearly, and adjust the size corresponding to the package substrate in a synchronous reduction or enlargement manner. The relevant mechanism is arranged in the machine under the base 2 and adopts the same linkage mechanism as the conventional one. The number of limit rods 3 is the same as the number of moving grooves 21, and each limit rod 3 is located in the relative moving groove 21 and can move along the moving groove 21 to achieve the purpose of synchronously reducing or enlarging the size.

The positioning plate 4 is in the shape of a plate with a size corresponding to the base 2. The positioning plate 4 has a plurality of positioning holes 41, and the enclosed area of the plurality of positioning holes 41 corresponds to the size of the package substrate to be used. In other words, when a different packaging substrate is used, a different positioning plate 4 must be replaced. The number of positioning holes 41 corresponds to the number of limit rods 3. After the above-mentioned limit rod 3 has moved and adjusted its position, the creative positioning plate 4 is used to place it on the base 2. During the process, each limit rod 3 is located in the corresponding positioning hole 41, so that the limit is synchronized and restricted. The position of the position rod 3 is maintained, and each limit rod 3 cannot be moved in subsequent operations. As shown in Figure 5, after placing one or more packaging substrates A on the base 2, because the position of the limit rod 3 is fixed, the packaging substrate A will not shift, so there will be no conventional signal errors. The base 2 rises, causing the package substrate A to be crushed or jammed.

As shown in FIG. 6, it is a top view of the first embodiment of the positioning plate of the packaging substrate feeding stage with the positioning plate. In this embodiment, the shape and size of the positioning hole 41 of the positioning plate 4 must be larger than the cross-sectional area of the limiting rod 3 to provide a proper margin. In addition to facilitating the insertion of the limiting rod 3 into the positioning hole 41, the positioning plate can also be avoided 4 When driven by the lifting seat to rise and fall, it interferes with the limit rod 3. In this example, the shape of the positioning hole 41 is square or rectangular, and the cross-sectional shape of the limiting rod 3 is quadrilateral.

As shown in Figure 7, it is a diagram of the second embodiment of this creation. In this embodiment, the positioning hole 41 of the positioning plate 4 is circular, and the size is still larger than the cross-sectional area of the limiting rod 3. In this way, the contact area between the positioning plate 4 and the limiting rod 3 can be reduced, and the friction between the positioning plate 4 and the limiting rod 3 can be avoided to generate static electricity and affect the packaging yield. In addition, the shape of the positioning hole 41 can also be quadrilateral, oval, etc., but it must be larger than the cross-sectional area of the limiting rod 3.

Based on the above, the packaging substrate feeding stage with positioning plate of the present invention is placed on the base 2 by the positioning plate 4, and the positioning hole 41 is used for the limit rod 3 to pass through and synchronously restrict its position. The limit rod 3 restricts the positions of the stacked multiple package substrates A to ensure that the package substrate A does not shift, which can avoid system misjudgments, reduce equipment failures, and improve equipment utilization, which meets the patent application requirements.
