[0031] In order to enable those skilled in the art to better understand the technical solutions of the embodiments of the present disclosure, the embodiments of the present disclosure are further described in detail below with reference to the drawings and specific embodiments.
[0032] As shown in FIGS. 1 to 5, the present disclosure provides a substrate fixing jig 100 for component mounting of a substrate, which comprises a fixing base 110, a carrier plate 120 arranged on the fixing base 110, and a fixing cover plate 130 arranged on the carrier plate 120. Figure 1 Figure 2 As shown in FIGS. 1 to 5, the present disclosure provides a substrate fixing jig 100 for component mounting of a substrate, which comprises a fixing base 110, a carrier plate 120 arranged on the fixing base 110, and a fixing cover plate 130 arranged on the carrier plate 120.
[0033] As shown in FIGS. 1 to 5, the present disclosure provides a substrate fixing jig 100 for component mounting of a substrate, which comprises a fixing base 110, a carrier plate 120 arranged on the fixing base 110, and a fixing cover plate 130 arranged on the carrier plate 120. Figure 5 As shown, the carrier 120 is provided with a plurality of fixing grooves 121, and a corresponding substrate 200 is fixed in each fixing groove 121. The number of the fixing grooves 121 is not specifically limited in this embodiment and can be selected according to the number of substrates for batch component placement.
[0034] A plurality of supporting bosses 111 corresponding to the positions of the substrates 200 are provided on one side of the fixing base 110 facing the carrier 120 . Each supporting boss 111 passes through the fixing slot 121 and is supported and fixed to the corresponding substrate 200 .
[0035] The cross section and size of the support boss 111 are smaller than the cross section of the substrate 200 to ensure that the support boss 111 can move up and down on the single substrate 200 of the carrier 120. The shape of the support boss 111 is not specifically limited and can be selected according to actual needs.
[0036] The fixed base 110 is provided with a first limiting structure 112, which abuts against the edge of the carrier 120 to limit the translation of the carrier 120, thereby limiting the translation of the substrate 200 in the horizontal direction, and plays a role in fixing the substrate 200 in the horizontal direction.
[0037] like Figure 4 As shown, the fixed cover plate 130 is provided with a plurality of guide grooves 131 at the corresponding base plate 200, and each base plate 200 is provided in the guide groove 131 corresponding thereto; wherein,
[0038] like Figure 4 As shown, a second limiting structure 132 is provided in the edge area of the fixed cover plate 130. The second limiting structure 132 abuts against the surface of the carrier plate 120 facing the fixed cover plate 130, and exerts a pressing effect on the carrier plate 120 to limit the warping of the carrier plate 120, thereby limiting the warping of the substrate 200 and fixing the substrate 200 in the vertical direction.
[0039] In addition, the fixed cover plate 130 is covered on the carrier plate 120 , and the fixed cover plate 130 itself presses the carrier plate 120 to limit the warping of the carrier plate 120 and further limit the warping of the substrate 200, thereby fixing the substrate 200 in the vertical direction.
[0040] Specifically, the fixed cover plate 130 is fixed on the equipment track at the upper part of the area to be mounted. A plurality of substrates 200 are fixed in the plurality of fixed grooves 121 of the carrier plate 120, and the carrier plate 120 is transported to the area to be mounted. The fixed base 110 is fixed on the equipment workbench. When the carrier plate 120 is located in the area to be mounted, the equipment workbench is raised so that the supporting boss 111 of the fixed base 110 supports and fixes the substrate 200 through the fixed groove 121, and the first limiting structure 112 abuts against the edge of the carrier plate 120 to limit the carrier plate 120 in the horizontal direction. After the fixed base 110 completes the limiting of the carrier plate 120, the equipment workbench continues to rise, so that the fixed cover plate 130 covers the carrier plate 120, and the fixed cover plate 120 and the second limiting structure can abut against the surface of the carrier plate 120 towards the fixed cover plate 130, so as to press the carrier plate 120 and limit the warping of the carrier plate 120. A plurality of substrates 200 are located in the guide groove 131 of the fixed cover plate 130, and then the substrates 200 are mounted with related components.
[0041] The substrate fixing jig of the embodiment of the present disclosure is used for component mounting of a substrate, and can meet the product batch production demand by fixing a carrier plate with a plurality of substrates. The first limiting structure provided on the fixed base can abut against the edge of the carrier plate, so as to limit the horizontal translation of the carrier plate and thus limit the horizontal translation of the substrate. The second limiting structure provided on the fixed cover plate can limit the warping of the carrier plate, so as to limit the vertical movement of the substrate and control the flatness of the substrate in the horizontal direction. The substrate fixing jig can fix the substrate during the component mounting process of the substrate, meet the product batch production, accurately mount the components on the substrate, improve the product yield and productivity, improve the turnover efficiency, ensure the product mounting quality, have zero scrap rate, have one-time investment, have long-term low cost investment, and save cost.
[0042] As shown in Figure 1 , Figure 2 and Figure 3 , the first limiting structure 112 is a limiting plate provided at both ends of the fixed base 110 along the length direction of the fixed base 110. When the carrier plate 120 is placed on the top of the fixed base 111, the limiting plate limits the two ends of the carrier plate 120 along the length direction, so as to limit the horizontal movement of the carrier plate 120.
[0043] Specifically, as shown in Figure 3As shown, the fixed base 110 includes a bottom plate 113, connecting plates 114 arranged on the left and right sides of the bottom plate 113, limiting plates arranged outside the connecting plates 114, and a bearing plate 115 arranged on the top of the connecting plates 114, and the bearing plate 115 is provided with a plurality of support bosses 111. When the load plate 120 is placed on the bearing plate 115, the limiting plates limit the left and right sides of the load plate 120, and the load plate 120 is prevented from moving left and right. Among them, two fixed rods 113a are arranged on the bottom plate 113, and the fixed base 110 is fixed on the equipment workbench through the fixed rods 113a.
[0044] As shown in the example, Figure 2 and Figure 3 As shown, the surface of the limiting plate facing the fixed cover plate 130 is an inclined surface inclined toward the load plate 120, which can more conveniently place the load plate 120 on the fixed base 110.
[0045] As shown in the example, Figure 4 As shown, the second limiting structure 132 is a limiting block arranged at the edge region of the side of the fixed cover plate 130 facing the load plate 120, and the limiting block abuts against the edge region of the load plate 120 to press the edge region of the load plate 120, control the flatness of the substrate 200 in the horizontal direction, and prevent the load plate 120 from warping.
[0046] It should be noted that the number of limiting blocks is not specifically limited in this embodiment, and can be selected according to actual needs. As shown in the example, Figure 4 In this embodiment, one limiting block is arranged at each of the two corner ends of the bottom edge region of the fixed cover plate 130, and of course, one limiting block can also be arranged at each of the four corner ends, which can be selected according to actual needs.
[0047] As shown in the example, Figure 4 As shown, the fixed cover plate 130 is provided with a third limiting structure 133 distributed along the periphery of the guide groove 131. The third limiting structure 133 is used to press the edge region of the substrate 200 to limit the warping of the substrate 200.
[0048] Specifically, during the lifting of the equipment workbench, the third limiting structure 133 presses the edge region of the substrate 200 located in the guide groove 131, which can directly apply pressure to the substrate 200 to limit the warping of the substrate 200.
[0049] In this embodiment, by arranging the third limiting structure on the fixed cover plate, the substrate can be directly pressed and fixed at the edge region of the substrate to control the flatness of the substrate in the horizontal direction, and further fix the substrate in the vertical direction.
[0050] Exemplarily, the third limiting structure 133 can be at least two elastic pressing pieces oppositely distributed. The first end of the elastic pressing piece is fixed to the fixed cover plate 130, and the second end of the elastic pressing piece is suspended in the guide groove 131 to abut against the edge region of the substrate 200.
[0051] In the embodiment, the third limiting structure adopts an elastic pressing piece, which buffers the pressure on the substrate during the lifting of the carrier plate, and does not damage the substrate. In addition, the elastic pressing piece plays a role in pressing and fixing the substrate.
[0052] It should be noted that the number and distribution position of the third limiting structure 133 are not limited in the embodiment, and can be selected according to actual needs. For example, in the embodiment, two third limiting structures 133 are distributed at two diagonal corner ends of the guide groove 131. Of course, four third limiting structures 133 can also be provided, and each limiting structure 133 is arranged at the corresponding corner end of the guide groove 131.
[0053] Exemplarily, the elastic pressing piece can include an elastic piece and a pressing block arranged at the end of the elastic piece. The pressing block abuts against the edge region of the substrate 200. Specifically, the first end of the elastic piece is fixed to the top of the fixed cover plate 130 around the guide groove 131, and the second end of the elastic piece is fixed with the pressing block. The pressing block can be made of resin material, which can prevent scratching of the substrate 200 when pressing the substrate 200, and ensure the reliability of the substrate 200.
[0054] Exemplarily, the elastic pressing piece and the fixed cover plate 130 can be integrally formed. Alternatively, the elastic pressing piece can be fixed to the fixed cover plate 130 by a fastener. The way in which the elastic pressing piece is fixed to the fixed cover plate 130 is not limited in the embodiment, and can be selected according to actual needs.
[0055] Exemplarily, as shown in Figure 4 , the edge region of the fixed cover plate 130 towards the carrier plate 120 is provided with a positioning column 134, as shown in Figure 5 , the carrier plate 120 is provided with a positioning hole 122 corresponding to the positioning column 134, and the positioning column 134 is inserted into the positioning hole.
[0056] In the embodiment, the positioning column arranged on the fixed cover plate plays a guiding role with the carrier plate, and realizes the alignment and fixation of the carrier plate and the fixed cover plate.
[0057] It should be noted that, as shown in Figure 4 , the edge region of the fixed cover plate 130 is provided with a fixing hole 135, and the fixed cover plate 130 can be fixed on the installation equipment track by cooperation of the fastener and the fixing hole 135.
[0058] Exemplarily, as shown in Figure 3As shown, the fixing base 110 is provided with a vacuum pipe inlet 116 for communicating with a vacuum source. The support boss 111 is provided with a plurality of vacuum suction holes, the first ends of the plurality of vacuum suction holes being in communication with the vacuum pipe inlet 116, and the second ends of the plurality of vacuum suction holes being used for suctioning the substrate 200.
[0059] Specifically, when the components of the substrate are mounted, the vacuum valve is opened, the fixing base 110 is vacuumized through the vacuum pipe inlet 116, and the substrate 200 is suctioned and fixed through the plurality of suction holes of the support boss 111.
[0060] As shown, Figure 5 As shown, the periphery of the fixing groove 121 of the carrier plate 120 is provided with a plurality of limiting columns 123, and the substrate 200 can be fixed in the fixing groove 121 through the plurality of limiting columns 123. The number of limiting columns 123 is not specifically limited in the embodiment, and can be selected according to actual needs.
[0061] As shown, Figures 1 to 5 The working principle of the substrate fixing jig of the embodiment of the present disclosure can be as follows:
[0062] The fixing cover plate 130 is fixed on the equipment track at the upper part of the to-be-mounted area through the cooperation of the fasteners and the fixing holes 135. The plurality of substrates 200 are fixed in the plurality of fixing grooves 121 of the carrier plate 120, and the plurality of limiting columns 123 limit and fix the substrates 200, and the carrier plate 120 is transmitted to the to-be-mounted stop area. The fixing base 110 is fixed on the equipment workbench through the fixing rod 113a. When the carrier plate 120 is located in the to-be-mounted stop area, the equipment workbench is raised and the vacuum pump is opened, the vacuum is introduced into the support boss 111 through the vacuum pipe inlet 116, and the substrates 200 are suctioned and fixed through the vacuum suction holes of the support boss 111. At the same time, the first limiting structure 112 abuts against the edge of the carrier plate 120 to limit the carrier plate 120 in the horizontal direction.
[0063] After the fixing base 110 completes the limiting of the carrier plate 120, the equipment workbench continues to rise, the fixing cover plate 130 is aligned with the carrier plate 120 through the positioning column 134 and is arranged on the carrier plate 120, after the alignment is completed, the carrier plate 120 is abutted against the surface of the fixing cover plate 130 through the fixing cover plate 130 itself and the second limiting structure, which plays a pressing role on the carrier plate 120 and limits the carrier plate 120 from being warped. In the alignment process, the third limiting structure 133 is arranged on the edge area of the substrate 200 located in the guide groove 131, which can directly apply pressure to the substrate 200 and limit the substrate 200 from being warped. The plurality of substrates 200 are located in the guide groove 131 of the fixing cover plate 130, and then the related components of the substrates 200 are mounted.
