[0023] The preferred embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0024] like Figures 1 to 6As shown, this embodiment provides a quick-detachable guide rail structure for a vertical tin spraying machine, including: a guide rail 1, a support rod 2 and a support module assembly 3, the support rod 2 is symmetrically arranged at both ends of the support module assembly 3, one end of the support rod 2 is connected to the support module assembly 3, and the other end of the support rod 2 is provided with a guide rail mounting seat 4, and the guide rail 1 is detachably arranged on the guide rail mounting seat 4.

[0025] The guide rail 1 described in this embodiment refers to the guide rail of the PCB circuit board, which is used to ensure that the PCB circuit board will not run around when entering the tin furnace 12. The support rod 2 is symmetrically arranged at the two ends of the tin furnace stirring assembly 3, and the guide rail mounting seat 4 is arranged on the inner bending end of the support rod 2, and the bending end is arranged at the end of the support rod 2 away from the support module assembly 3; the guide rail 1 is detachably arranged at the end of the support rod 2 away from the support module assembly 3 through the guide rail mounting seat 4, so that the guide rails 1 symmetrical at both ends can be quickly assembled, so as to achieve the fixing and installation of the PCB circuit board through the guide rails 1 symmetrically arranged at both ends. In the actual production process, the support module assembly 3 can also be replaced by a screw assembly. This embodiment adopts a matching quick-release structure design, which makes the disassembly and installation process of the guide rail 1 simpler and more efficient, and no longer needs to readjust the accuracy, thereby effectively improving the production efficiency and shortening the production time of the product.

[0026] Preferably, Figures 1 to 6 As shown, mounting arms 5 are provided at both ends of the support module assembly 3 in this embodiment, and the support rod 2 is detachably provided on the mounting arms 5. That is to say, in this embodiment, not only the guide rail 1 is detachably designed, but also the support rod 2 for mounting the guide rail 1 is detachably designed, thereby better meeting the production requirements of different tin furnaces 12 or different PCB circuit boards.

[0027] like Figure 1 As shown, in this embodiment, the mounting arm 5 is provided with a reinforcing rib 6, and the reinforcing rib 6 is arranged on a side of the mounting arm 5 away from the supporting rod 2, so as to ensure that sufficient supporting force is provided.

[0028] More specifically, Figures 1 to 4 As shown, a concave mounting groove 7 is arranged at the top of the mounting arm 5 of the present embodiment, and a T-shaped mounting portion 8 matching the concave mounting groove 7 is arranged at one end of the support rod 2, and the T-shaped mounting portion 8 and the concave mounting groove 7 are detachably connected, so that the support rod 2 can be quickly installed and removed by snap-in.

[0029] As shown in the figure Figure 4As shown, since the guide rail 1 needs to be inserted into the tin furnace 12, the size requirement is higher. Therefore, unlike the detachable structure of the support rod 2, the guide rail mounting seat 4 of this embodiment is provided with an insertion hole 9, and the outer side of the guide rail 1 is provided with an insertion end 10 matching the insertion hole 9. The insertion end 10 is detachably connected to the insertion hole 9, so that the outer side of the guide rail 1 can be inserted and quickly installed and removed between the support rod 2. After taking out the guide rail 1 each time, when installing the guide rail 1 again, it is only necessary to align the guide rail 1 with the insertion hole 9 and insert it into place, and there is no need to readjust the accuracy. Therefore, the fixing accuracy of the quick-detachable guide rail structure can be improved through the optimized design of the structure, which provides a better basis for reducing the product scrap rate caused by falling off the cylinder.

[0030] It is worth noting that if Figure 1 and Figure 3 As shown, the inner top of the guide rail 1 of this embodiment is provided with a trumpet-shaped introduction port 11, which is large at the top and small at the bottom, so as to facilitate the rapid insertion and removal of the PCB circuit board; at the same time, it can also better improve the fixing accuracy of the guide rail structure to reduce the product scrap rate caused by falling out of the cylinder. Preferably, the trumpet-shaped introduction port 11 also includes a recessed mounting hole 19, which refers to a reserved recessed hole position structure, which is not a necessary structural feature. The reserved recessed hole position structure can facilitate the matching of screws or limiters and other structures according to actual application requirements to achieve the function of fixing and limiting.

[0031] In practical applications, the tin furnace stirring assembly 3 of this embodiment is arranged on the side or above the tin furnace 12, such as Figure 5 As shown, the support module assembly 3 is arranged on the side of the tin furnace 12, and the guide rail 1 is inserted into the tin furnace 12 from the top of the tin furnace 12 through the support rod 2, so as to ensure that the PCB circuit board will not move around when entering the tin furnace 12.

[0032] Preferably, the center point of the guide rail 1 in this embodiment coincides with the center point of the tin furnace 12. That is, the center axis between the guide rails 1 at both ends of the molding or screw assembly 3 coincides with the center axis of the tin furnace 12. With such a design, regardless of the size of the PCB product, it can be fixed in the middle position of the tin furnace 12 as the guide rail 1 is raised or lowered, and because the center point of the guide rail 1 coincides with the center point of the tin furnace 12, it is ensured that the center point of PCB products of different sizes does not change during the left and right movement of the guide rail 1, thereby better ensuring its tin spraying effect.

[0033] like Figure 1 and Figure 6As shown, the support module assembly 3 described in this embodiment includes a servo motor 13, a base 14, a sliding seat 15 and a mounting seat 16, wherein the mounting seat 16 is arranged above the base 14 and the sliding seat 15, and the sliding seat 15 is arranged between the base 14 and the mounting seat 16, and the support rod 2 is arranged above the mounting seat 16, that is, the support rod 2 is connected to the mounting seat 16 through the mounting arm 5, and the base 14 is connected to the servo motor 13, so that under the action of the servo motor 13, the base 14 and the mounting seat 16 can achieve relative movement in the left and right directions, and the track 1 is driven to move left and right through the mounting arm 5 and the support rod 2.

[0034] More preferably, the support module assembly 3 described in this embodiment also includes an accordion protection cover 17, and the accordion protection cover 17 is arranged on the base 14 and between the mounting baffles 18 at both ends of the base 14, so as to play a protective role when relative movement in the left and right directions is realized between the base 14 and the mounting seat 16.

[0035] In summary, the present embodiment provides a guide rail 1 and a support rod 2 of matching design, wherein the support rod 2 is symmetrically arranged at both ends of the tin furnace stirring assembly 3, one end of the support rod 2 is connected to the support module assembly 3, and the other end of the support rod 2 is provided with a guide rail mounting seat 4, and the guide rail 1 is detachably arranged on the guide rail mounting seat 4, so that it can be quickly disassembled and installed through a matching structure, and there is no need to readjust the accuracy, which effectively improves production efficiency and shortens product production time. On this basis, the present embodiment further optimizes the structure of the guide rail 1, the support rod 2 and the support module assembly 3, improves the fixing accuracy of the guide rail structure, and reduces the product scrap rate due to falling out of the cylinder.
