[0010] The diodes to be packaged are located in the placement interval, with the leads at both ends of the diodes located in the slots. By setting an adjustment unit, the position of the leads at both ends of a row of diodes in the placement interval is controlled by the limiting strips that abut against the outer ends of the leads, thus playing a limiting role. Moreover, the limiting strips are detachable, and the position of the lead ends of the diodes abutting against the limiting strips can be controlled by replacing the limiting strips of different widths. This not only allows for the packaging of diodes of different specifications and sizes, but also allows for the adjustment of the deviation of the leads at both ends.

[0043] Example 1

[0044] As Figures 1-3The utility model provides a kind of carrying frame for diode packaging, it includes: bottom frame 1, bearing strip 2 and adjusting unit 5.

[0045] Bottom frame 1 is the frame type structure that four sides surround middle empty out;Multiple bearing strips 2 are arranged at intervals in the bottom frame 1, specifically arranged into two columns multiple rows, spaced apart from each other, and inner wall surface of bottom frame 1 is connected to form an integral, the placing interval 3 is formed between longitudinally adjacent bearing strips 2, and the edge of bearing strip 2 close to the placing interval 3 is arranged with several clamping grooves 4, specifically, clamping groove 4 is formed by several interval setting protrusions, clamping groove 4 is formed between two protrusions, to accommodate the lead end of diode.

[0046] Adjusting unit 5 includes several limiting strips 501, the limiting strip 501 is detachably connected on the bearing strip 2, the limiting strip 501 is located on the side of the clamping groove 4 away from the placing interval 3, for abutting diode lead outer end, while, limiting strip 501 and the outside of clamping groove 4 have a certain gap, to facilitate the adjustment and the distance of the outside of clamping groove 4, when the diode to be packaged is located in the placing interval 3, the lead of both ends of diode is located in the clamping groove 4, by setting adjusting unit 5, the position of the lead of both ends of a row of diode in placing interval 3 is controlled by the abutting of limiting strip 501 in it, plays the limiting role;

[0047] And limiting strip 501 is detachably connected, can change the gap between limiting strip 501 and the outside of clamping groove 4 by replacing limiting strip 501 of different width, not only suitable for packaging diode of different specifications and sizes, but also can control the position of the lead of both ends of diode abutting limiting strip 501, to adjust the deviation of the lead of both ends, to avoid larger error when packaging.

[0048] To facilitate the adjustment of the distance of limiting strip 501 on both sides of each placing interval 3, the adjusting unit 5 further includes a bottom plate 502, the bottom plate 502 is detachably connected with the bearing strip 2, and the two limiting strips 501 are detachably connected on the bottom plate 502, and the two limiting strips 501 are located on the outside of the clamping groove 4 on both sides of the placing interval 3.

[0049] By setting the bottom plate 502, and setting the two limiting strips 501 on the bottom plate 502, the distance between the two limiting strips 501 can be measured and controlled on the bottom plate 502 after the bottom plate 502 and the limiting strips 501 are detached, and then the whole is installed in the bearing strip 2 of the bottom frame 1, to ensure the accuracy of the size between the two limiting strips 501;In addition, the bottom plate 502 and the limiting strip 501 can be detached and replaced, and after the bottom plate 502 and the limiting strip 501 are deformed too much, they can be replaced and maintained by replacing the limiting strip 501 and the bottom plate 502 to continue to use.

[0050] Meanwhile, different limiting strips 501 and bottom plates 502 can be selected according to different sizes to meet different size requirements.

[0051] In this embodiment, as shown in the figure, the bottom plate 502 comprises two clamping strips 5021 and a connecting block 5022. Figure 3

[0052] The side surface of the clamping strip 5021 abuts against the side of the clamping groove 4 away from the placement interval 3, the limiting strip 501 is connected to the clamping strip 5021, the connecting block 5022 is connected to one end of the two clamping strips 5021, the side of the connecting block 5022 away from the clamping strip 5021 abuts against the inner wall surface of the bottom frame 1, the whole formed by the clamping strip 5021 and the connecting block 5022 is connected to the inner wall surface of the bottom frame 1, the clamping strip 5021 is limited and clamped outside the clamping groove 4, and the whole forms a U-shaped structure embracing the outside of the clamping groove 4, thereby playing a positioning role.

[0053] On this basis, the positioning and fastening mode can adopt an additional screw fastener 505 for fastening connection to ensure that the bottom plate 502 is fastened and connected with the bearing piece.

[0054] To ensure the connection and fastening and position each bottom plate 502, a positioning screw 503 is screwed through the connecting block 5022 and connected with the bearing strip 2.

[0055] The positioning screw 503 fastens the connecting block 5022 and the bearing strip 2, and at the same time that the bottom plate 502 forms a U-shaped structure clamped outside the clamping groove 4, the positioning screw 503 further maintains the stability of the bottom plate 502 connected with the bearing strip 2, and in addition, the positioning screw 503 can also play a positioning role.

[0056] Specifically, the top of the positioning screw 503 is higher than the surface of the bottom frame 1, and the part of the positioning screw 503 higher than the surface of the bottom frame 1 can play a positioning role, thereby ensuring that the fixed position of the bottom plate 502 remains stable and unchanged.

[0057] As shown in the figure, Figure 4 ​As shown, to adjust the dimensional deviation at both ends of the diode without replacing the limiting strip 501, the limiting strip 501 has several strip-shaped holes 504.

They are used to pass through the strip-shaped holes 504 on the limiting strip 501 and are fixedly connected to the retaining strip 5021 in the base plate 502. Since the strip-shaped holes 504 are parallel to the length direction of the diode, before tightening the fasteners 505, the limiting strip 501 can be finely adjusted through the strip-shaped holes 504 to adjust the distance between itself and the retaining strip 4, thereby adjusting the distance to the outer end of the diode lead and solving the problem of excessive difference in the dimensions on both sides of the lead. After adjustment, the position of the limiting strip 501 is fixed by tightening the fasteners 505, thereby determining the distance between the two limiting strips 501.

[0058] like Figure 5 , 6 As shown, to ensure that the two limiting bars 501 remain parallel during adjustment, a limiting groove 506 is provided on the side of the limiting bar 501 near the base plate 502. The long axis of the limiting groove 506 is parallel to the length direction of the diode. The base plate 502 is provided with a limiting protrusion 507 that matches the limiting groove 506. The limiting groove 506 and the limiting protrusion 507 are respectively provided at the bottom of the limiting bar 501 and the top of the retaining bar 5021, respectively, and limit each other. The limiting groove 506 and the limiting protrusion 507 are provided in multiple groups. By using the cooperation of multiple limiting grooves 506 and limiting protrusions 507, the limiting bar 501 can be limited by the limiting groove 506 when it moves and is adjusted, and always maintains a straight state to be adjusted close to or away from the diode lead, thus ensuring the consistency of a batch of diode leads in a placement interval 3.

[0059] Specifically, the limiting groove 506 can be formed around the outside of the strip hole 504, and the limiting protrusion 507 is set corresponding to the fastener 505. The top of the limiting protrusion 507 has a screw hole for cooperating with the screw. At this time, the limiting protrusion 507 is an annular limiting protrusion. Figure 6 As shown.
