[0039] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0040] In order for those skilled in the art to better understand the technical solutions of the present application, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0041] The embodiments of the present application disclose a product carrier for a reflow oven, as shown in the accompanying drawings, which comprises a carrier plate 1 and at least two groups of support frame groups 2. Figures 1 to 3 The carrier plate 1 is provided with a plurality of groups of fixing grooves 10, and at least part of the fixing grooves 10 are detachably and fixedly provided with the support frame groups 2.

[0042] Each set of support frame groups 2 forms a loading slot 20 for supporting the product 3. The product 3 includes wide and narrow frames of different widths. The wide frame can be an 83mm TSOT23 frame, and the narrow frame can be a 48mm SOT-563 frame, etc. At least two sets of support frame groups 2 can form at least two loading slots 20, wherein the width of the at least two loading slots 20 is different. The loading slots 20 of different widths are used to support products 3 of different specifications. In this way, the product carrier can support at least two different specifications of products 3, which has good versatility and can adapt to different specifications of products 3. There is no need to repeatedly adjust the width of the equipment, saving ineffective time and reducing production costs.

[0043] The support frame group 2 is detachable, which allows the position of the support frame group 2 on the support plate 1 to be adjusted at will. The width of the loading groove 20 can be adjusted by adjusting the distance between the two support bars of each support frame group 2 to adapt to products 3 of different specifications, resulting in lower production costs.

[0044] In the first specific embodiment, as shown in the appendix Figure 9 As shown, the fixing groove 10 includes two sets of first fixing grooves 101 and two sets of second fixing grooves 102. Each set of fixing grooves 101 is provided with a set of second fixing grooves 102, that is, the two sets of first fixing grooves 101 and the two sets of second fixing grooves 102 are nested in pairs.

[0045] As attached Figure 3 As shown, the support frame group 2 includes two sets of first support frame groups 21 and two sets of second support frame groups 22. The two sets of first support frame groups 21 are detachably fixed in the two sets of first fixing grooves 101, and the two sets of second support frame groups 22 are detachably fixed in the two sets of second fixing grooves 102, so that the two sets of first support frame groups 21 and the two sets of second support frame groups 22 are nested in pairs. The first loading groove formed by the first support frame group 21 and the second loading groove formed by the second support frame group 22 are stacked in pairs, that is, the first loading groove formed by one set of first support frame group 21 and the second loading groove formed by one set of second support frame group 22 are stacked in pairs.

[0046] As a preferred embodiment, as shown in the appendix Figure 3As shown, each of the first support frame groups 21 includes two first support bars 211 arranged in parallel, and each of the second support frame groups 22 includes two second support bars 221 arranged in parallel. The two first support bars 211 are arranged higher than the two second support bars 221, and the distance between the two first support bars 211 is greater than the distance between the two second support bars 221, so that the width of the first product slot is greater than the width of the second product slot. The first support frame groups 21 are nested with the second support frame groups 22, i.e., the two first support bars 211 are arranged with the two second support bars 221 therebetween, so that the first product slot and the second product slot are arranged in a stacked manner, and the first product slot is arranged above the second product slot. The first product slot and the second product slot are respectively suitable for carrying two products 3 of different widths. Of course, the number of the first support frame groups 21 and the second support frame groups 22 can be more than two. In the first specific embodiment, the product carrier can carry two products 3 of different specifications, wherein the two first support frame groups 21 are used to carry two wide frames of the same specification, and the two second support frame groups 22 are used to carry two narrow frames of the same specification.

[0047] As shown in the accompanying drawings, Figure 1 As shown, the support frame group 2 includes two support bars arranged in parallel, and the two support bars of the same support frame group 2 have the same height. For the same support frame group 2, the opposite sides of the two support bars are respectively provided with clamping grooves 24, and all the clamping grooves 24 of the two support bars are opposite to each other. The clamping grooves 24 of the two support bars are opposite to each other to form a product slot 20, which clamps two opposite sides of the product 3 to achieve the carrying of the product 3. The thickness of the clamping groove 24 can be set according to the thickness of the product 3. At least one end of each clamping groove 24 is formed with a material guiding port 23, which is trumpet-shaped. When the product 3 is loaded into the product slot 20, the loading difficulty of the product 3 is reduced, the loading is facilitated and fast, the loading time is saved, the loading efficiency is improved, and the production cost is reduced. Specifically, each clamping groove 24 is provided with a material guiding port 23 at each end. The material guiding port 23 is surrounded by three inclined surfaces corresponding to the upper top surface, the lower bottom surface and the side surface end of the clamping groove 24. The cross-sectional area of the material guiding port 23 is greater than the cross-sectional area of the product 3, and the cross-sectional area of the material guiding port 23 gradually decreases in the direction close to the clamping groove 24. Of course, the structure of the material guiding port 23 is not limited to this.

[0048] As shown in the accompanying drawings, Figure 2As shown, the support bar is integrally formed with at least two layers of laminated layer plates, and a clamping groove 24 is formed between any two adjacent layer plates. A set of support frame groups 2 can carry at least two products 3 in a laminated manner. The number of products 3 that can be carried by each set of support frame groups 2 is increased, a set of product carriers is saved, and production costs are reduced. It should be noted that one end of the uppermost layer plate is provided with a notch 25 to reduce the contact area between the product 3 and the uppermost layer plate. The product 3 is guided and carried by the layer plate below and loaded into the clamping groove 24, which reduces the difficulty of loading the product 3, saves time, and reduces production costs. The notch 25 in the text is formed by the missing part of one end of the uppermost layer plate. Of course, each support bar can be provided with only one clamping groove 24, or two or more clamping grooves 24.

[0049] The carrying plate 1 is formed with a plurality of guide grooves 11, and the support bars of all the support frame groups 2 are selectively loaded into the guide grooves 11, that is, only part of the guide grooves 11 are loaded with support bars, or all the guide grooves 11 are one-to-one correspondingly loaded with a support bar. The carrying plate 1 is a rectangular plate, and the guide grooves 11 can be rectangular grooves extending along the width direction of the carrying plate 1. The guide grooves 11 are used to guide the loading of the support bars and to limit the position of the support bars on the carrying plate 1. A locking member is provided between the support bar and the guide groove 11 for fixing the support bar in the guide groove 11 after loading, so as to avoid accidental sliding of the support bar relative to the guide groove 11 during the material moving process, thereby preventing the product 3 from accidentally falling off and ensuring safety. The locking member is of a detachable structure, which facilitates the disassembly and assembly of the support bar. The locking member can be a locking screw, but is not limited thereto. Of course, the mounting mode between the support bar and the guide groove 11 is not limited thereto. As a preferred embodiment, the carrying plate 1 is provided with a plurality of guide grooves 11 in parallel

[0050] As shown in the accompanying drawings Figure 1 At least one side of the guide groove 11 is protruded to form a guide boss 12. The provision of the guide boss 12 can increase the depth of the guide groove 11 to some extent, increase the contact area between the guide groove 11 and the support bar, thereby increasing the embedding depth of the support bar in the guide groove 11, and further increasing the carrying capacity of the support bar, avoiding the support bar from accidentally separating from the guide groove 11 during the loading process due to the too small embedding depth, and improving the safety.
