Board support

The present invention is a support base, especially a support base disposed on a processing machine for providing elastic support to a circuit board.

According to the advancement of technology, the automation technology of the semiconductor industry has been widely introduced to reduce the consumption of manpower in the process and improve the yield of products. In the automated process of the circuit board, the circuit board is moved to various processing machines through the conveyor belt. To place the electronic components into the circuit board, the conveyor belt transports the circuit board to the placement machine, and the placement machine can In the packaging process, the electronic components are sucked and moved to the position of the board to be placed, and then the electronic components are pressed and pressed onto the circuit board to use the surface mounted technology (SMT) to electronic components. Installed on the circuit board.

Since the circuit board is usually flexible, if a part of the circuit board is subjected to excessive pressing force, bending deformation occurs, which causes peeling of other electronic components on the circuit board. When the area of the circuit board is larger, the pressing force is applied. The greater the magnitude of the bending deformation produced, the more likely it is to cause damage to the board during the placement process, which in turn affects the yield of the finished board.

In addition, the cross-sectional area of the rear end of the rigid member 122 is smaller than the cross-sectional area of the first insertion hole 111 or the second insertion hole 112, so that each of the support columns 12 is inserted through the tail end of the rigid member 122. The first jack 111 or the second jack 112 is pulled away from one of the first jack 111 and the second jack 112. Please refer to FIG. 6 and FIG. 7 , which are schematic diagrams of another embodiment of the circuit board support seat. As shown in FIG. 6 , the circuit board support 1 of the present invention can adapt to the circuit board to be supported and adjust the support column. 12, in the number and position of the support body 11, the part of the support column 12 can be pulled away from the first socket 111 or the second socket 112, please refer to FIG. 7, so that the elastic member 121 of the support column 12 The contact with the electronic component 21 or the solder paste on the support surface of the circuit board 2 can be avoided, thereby preventing the elastic member 121 from being contaminated by tin contamination and affecting the subsequent process.

In order to maintain the number and position of the support pillars after the board support is adjusted, the circuit board support of the present invention can also be provided with a positioning plate for positioning the support column, so that the support column can be kept on the support base. As shown in FIG. 2, in the embodiment, the positioning plate 13 has a plurality of third insertion holes 131 and a plurality of fourth insertion holes 132. The support base 11 has a rail 113, and the guide positioning plate 13 enters the support base. The body 11 is configured such that the positions of the third insertion hole 131 and the fourth insertion hole 132 respectively correspond to one of the first insertion hole 111 and the second insertion hole 112, and the rigid parts of each of the support columns 12 are ordered. 122 is inserted along the first insertion hole 111 or the second insertion hole 112 to the third insertion hole 131 or the fourth insertion hole 132 corresponding to the position. In addition, the rails 113 of the support base 11 can also guide the positioning plate 13 to move relative to the support columns 12 inserted into the third and fourth insertion holes 131 and 132 to make the holes of the third and fourth insertion holes 131 and 132. The walls respectively abut the rigid members 122 of the support column 12, and the positioning of each of the support columns 12 is accomplished by a clamping force. The positioning plate 13 further has an urging portion 133 that exposes the support base 11 such as a sheet-like body, and the urging force drives the positioning plate 13 to move in the support base 11.

In the embodiment, the circuit board support base 1 can also be provided with a spring 14 , and the two ends of the spring 14 respectively contact the support base 11 and the positioning plate 13 . Moreover, the rear end of each of the rigid members 122 can also be formed with a positioning groove 123, and the spring 14 can provide an elastic force to move the positioning plate 13 relative to the support base 11, so that a part of the plate of the positioning plate 13 is embedded or separated from the rigidity. The positioning slot 123 of the member 122. When a part of the plate body of the positioning plate 13 is embedded in the positioning groove 123, as shown in FIG. 4, the longitudinal movement of each of the support columns 12 and the elastic members 121 and the rigid member 122 is restricted. At this time, the support column 12 cannot be The support base 11 is easily removed, and the number and position of the support columns of the support base can be effectively maintained, thereby completing the positioning of the support column. When a part of the plate body of the positioning plate 13 leaves the positioning groove 123, as shown in FIG. 5, the longitudinal movement of each of the support columns 12 is not restricted, and the support base 11 can be removed, so that the support column can be released. The positioning can be adapted to the number of support columns that are inserted into the support base and the position of the support plate to be supported.

In addition, the positioning plate 13 further has a first limiting member 134. Correspondingly, the inlet of the supporting base 11 rail 113 is further provided with a second limiting member 15. In the embodiment, the first limiting member 134 is a columnar body. The second limiting member 15 is a stopper, but the structural design of the first and second limiting members 134, 15 should not be limited thereto. The structural design of the supporting base 11 and the positioning plate 13 can be applied to the positioning plate 13. The movement stroke is limited, and both can be used as the first and second restriction members 134, 15 of the present creation. As shown in FIG. 4, when the urging force of the urging portion 133 is released, the spring 14 can provide elastic force to push against the positioning plate 13 in a direction away from the support base 11 until it contacts the first and second restricting members 134, 15. Thus, in order to limit the movement stroke of the positioning plate 13, the movement stroke of the positioning plate 13 is prevented from being excessively large, and the support column 12 is inclined or damaged by the shear force. In other embodiments, the spring 14 can also provide elastic force to move against the positioning plate 13, so that a part of the plate of the positioning plate 13 is separated from the positioning groove 123, and the positioning of the support column 12 is released.

It should be noted that, in the circuit board support of the present invention, if the number and position of the support columns are adjusted very frequently, the positioning plate and the spring and the like disclosed in the above embodiments may be omitted and rigid. The rear end of the piece also needs to form a positioning groove, so that not only the support column can be easily pulled away from the support base, but also the structure of the support board of the present circuit board can be simplified and the manufacturing cost can be reduced.

As shown in FIG. 2, the circuit board support base 1 is further provided with a storage box 16 which is disposed on the support base 11 and can be opened from the side of the support base 1. When the storage box 16 is opened, the storage box 16 can be opened. The support post 12 that has been withdrawn from the first insertion hole 111 or the second insertion hole 112 is placed in its storage space and stored to prevent the extracted support column 12 from being lost. In other implementations, the arrangement of the storage box in the circuit support base may also be omitted to simplify the structure of the support board of the present circuit board.
