Description

Technical Field

[0001] This utility model relates to the technical field of reflow soldering equipment, specifically to a quick-release and quick-installation structure for a reflow soldering furnace cover. Background Technology

[0002] Reflow ovens are widely used in the soldering of printed circuit boards (PCBs). By precisely controlling the temperature and time, they ensure that electronic components can be reliably soldered onto the PCB. The reflow oven cover is an important component of the reflow oven, and its main function is to seal the oven body to prevent heat loss and external contamination.

[0003] During the installation of the reflow oven cover, it is usually necessary to align the positioning holes of the reflow oven cover with the fixing position, and then tighten the fastening bolts one by one to install and fix the reflow oven cover through the bolt connection. When it is necessary to remove the reflow oven cover, loosen the fastening bolts one by one, and finally remove the reflow oven cover.

[0004] Existing reflow oven covers, while capable of installation and removal via bolt connections, typically require multiple bolts. In confined spaces, each bolt must be tightened or loosened individually, increasing the complexity of installation and disassembly and adding significant time to each process, further prolonging the overall time spent on reflow oven cover assembly and disassembly. Therefore, a quick-release and quick-installation structure for reflow oven covers is proposed. Utility Model Content

[0005] To address the problems in the background technology, this utility model provides the following technical solution: a quick-release and quick-install structure for a reflow oven cover plate, comprising a plate body, positioning holes respectively provided on the rear side of the upper end of the plate body, sliding grooves respectively provided on the front side of the upper end of the plate body, mounting seats respectively provided on the upper sides of the left and right ends of the plate body, and also including a fixing mechanism.

[0006] The fixing mechanism includes trapezoidal blocks and push plates. The trapezoidal blocks are slidably connected to the mounting grooves opened on the upper side of the mounting base at the end away from the center of the plate. Push plates are provided on the upper side of the four mounting bases. The end of the push plate away from the center of the plate contacts the end of the horizontally adjacent trapezoidal block near the center of the plate.

[0007] Furthermore, the fixing mechanism also includes a crossbar and a connecting plate. The crossbar is respectively disposed on the upper side inside the mounting base. The side of the outer arc surface of the crossbar away from the center of the plate is slidably connected to the connecting plate. A trapezoidal block is fixedly connected between the opposite inner surfaces of two longitudinally adjacent connecting plates to prevent the position of the trapezoidal block from shifting.

[0008] Furthermore, the fixing mechanism also includes uprights and mounting plates. The uprights are respectively disposed inside the mounting base. Mounting plates are slidably connected to the upper side of the outer arc surface of the uprights. A push plate is fixedly connected between the opposite inner sides of two longitudinally adjacent mounting plates. The four push plates are respectively located between the ends of two longitudinally adjacent horizontal bars that are close to the center of the interior of a vertically adjacent mounting base, which can prevent the position of the push plates from shifting.

[0009] Furthermore, the fixing mechanism also includes a sliding column and a pressure plate. The sliding column is slidably connected to the guide groove provided at the upper end of the plate. The upper end of each sliding column is provided with a pressure plate. The lower end of each sliding column is fixedly connected to the upper end of the vertically adjacent push plate, which can drive the push plate to move.

[0010] Furthermore, springs are respectively provided between the end of the connecting plate near the center of the plate body and the inner wall of the mounting base. The springs are movably connected to the corresponding horizontal bars. The tension generated by the spring contraction will drive the trapezoidal block to move along the inclined surface of the push plate towards the end near the center of the plate body through the connecting plate.

[0011] Furthermore, a return spring is provided between the lower end of the mounting plate and the bottom wall of the mounting base. The return springs are all sleeved on the outside of the lower side of the upright. The thrust generated by the extension of the return spring will drive the push plate to move upward and reset through the mounting plate.

[0012] Furthermore, protective covers are provided on the front and rear sides of the upper end of the plate, and limit seats are provided on the upper side of the inside of the protective covers. The lower end of the limit seats contacts the upper end of the vertically adjacent pressure plates, and the middle of the lower end of the limit seats is provided with a relief groove. The protective covers can protect the pressure plates and prevent accidental contact that could affect the stability of the plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are: by using the combination of trapezoidal blocks and push plates, the reflow oven cover can be quickly installed or disassembled, optimizing the fixing method and replacing the traditional method of installing the reflow oven cover by bolt connection, reducing the complexity of installation and disassembly, and further shortening the time spent on installing and disassembling the reflow oven cover.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This embodiment provides a technical solution: a quick-release and quick-install structure for a reflow oven cover plate, including a plate body 1, with positioning holes 2 respectively provided on the rear side of the upper end of the plate body 1, with sliding grooves 10 respectively provided on the front side of the upper end of the plate body 1, and mounting seats 3 respectively provided on the upper sides of the left and right ends of the plate body 1.

[0021] The system also includes a fixing mechanism 4; the fixing mechanism 4 includes trapezoidal blocks 43 and push plates 46. The trapezoidal blocks 43 are slidably connected to the mounting grooves on the upper side of the end of the mounting base 3 away from the center of the plate 1. The upper side of the interior of each of the four mounting bases 3 is provided with push plates 46. The end of the push plates 46 away from the center of the plate 1 contacts the end of the laterally adjacent trapezoidal blocks 43 near the center of the plate 1. The fixing mechanism 4 also includes crossbars 41 and connecting plates 42. The crossbars 41 are respectively set on the upper side of the interior of the mounting base 3. The side of the outer arc surface of the crossbars 41 away from the center of the plate 1 is slidably connected to the connecting plates 42. The inner sides of two longitudinally adjacent connecting plates 42 are fixedly connected by a... The fixing mechanism 4 also includes a trapezoidal block 43; the fixing mechanism 4 also includes a vertical rod 44 and a mounting plate 45. The vertical rod 44 is respectively set inside the mounting base 3. The upper side of the outer arc surface of the vertical rod 44 is slidably connected to the mounting plate 45. A push plate 46 is fixedly connected between the opposite inner sides of two longitudinally adjacent mounting plates 45. The four push plates 46 are respectively located between the ends of two longitudinally adjacent horizontal bars 41 near the center of the interior of a vertically adjacent mounting base 3. The fixing mechanism 4 also includes a sliding column 47 and a pressure plate 48. The sliding column 47 is slidably connected to the guide groove set at the upper end of the plate body 1. The upper end of the sliding column 47 is set with a pressure plate 48. The lower end of the sliding column 47 is fixedly connected to the upper end of the vertically adjacent push plate 46.

[0022] Wherein: A spring 5 is provided between the end of the connecting plate 42 near the center of the plate body 1 and the inner wall of the mounting base 3. The spring 5 is movably connected to the horizontal bar 41 corresponding to the horizontal direction. The tension generated by the contraction of the spring 5 will drive the trapezoidal block 43 to move along the inclined surface of the push plate 46 towards the end near the center of the plate body 1 through the connecting plate 42.

[0023] Among them, a reset spring 6 is provided between the lower end of the mounting plate 45 and the bottom wall of the mounting base 3. The reset spring 6 is sleeved on the outside of the lower side of the upright 44. The thrust generated by the extension of the reset spring 6 will drive the push plate 46 to move upward and reset through the mounting plate 45.

[0024] Among them: protective covers 7 are respectively provided on the front and rear sides of the upper end of the plate 1. Limit seats 8 are provided on the upper side of the inside of the protective cover 7. The lower end of the limit seat 8 contacts the upper end of the vertically adjacent pressure plate 48. The middle part of the lower end of the limit seat 8 is provided with a relief groove 9. The protective cover 7 can protect the pressure plate 48 and prevent accidental contact from affecting the stability of the plate 1.

[0025] The working principle of this utility model is as follows:

[0026] During the installation of the reflow oven cover, the operator inserts the plate 1 into the corresponding fixed position. When inserting the plate 1, the plate 1 will drive the trapezoidal block 43 to move. Finally, the plate 1 contacts the inner wall of the fixed position through the inclined surface of the lower end of the trapezoidal block 43 away from the inner center of the plate 1, ensuring that the trapezoidal block 43 can be tightly embedded in the interior of the fixed position, so that the trapezoidal block 43 is close to the inner wall of the fixed position, and finally forms a stable support, thereby realizing the installation and fixing of the reflow oven cover.

[0027] When it is necessary to remove the reflow oven cover, the operator inserts their fingers into the clearance groove 9 and presses the pressure plate 48. After the pressure plate 48 is subjected to pressure, it will drive the push plate 46 to move downward through the sliding column 47. The return spring 6 retracts. When the inclined surface of the upper end of the push plate 46 contacts the inclined surface of the lower end of the trapezoidal block 43 near the center of the inner side of the plate body 1, the tension generated by the retraction of the spring 5 will drive the trapezoidal block 43 to move along the inclined surface of the push plate 46 towards the end near the center of the inner side of the plate body 1 through the connecting plate 42. At this time, the trapezoidal block 43 will loosen from the inner wall of the fixed station. Then, the fingers are removed and the above operation is repeated to loosen all four trapezoidal blocks 43 from the inner wall of the fixed station. Finally, the reflow oven cover can be removed.

[0028] After the reflow oven cover is removed, the thrust generated by the extension of the reset spring 6 will drive the push plate 46 to move upward and reset through the mounting plate 45. During the movement of the push plate 46, the push plate 46 will push the trapezoidal block 43 through the inclined surface. The spring 5 extends, and finally the end of the push plate 46 away from the center of the plate body 1 will re-contact the end of the laterally adjacent trapezoidal block 43 close to the center of the plate body 1, thereby driving the trapezoidal block 43 to move and reset through the push plate 46.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
