DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] Next, the technical solutions in the embodiments of this utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, rather than all the embodiments. Based on the embodiments in this utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this utility model.

[0029] Please refer to Figure 1, the present utility model provides a technical solution: an energy-saving warming rack for solder paste processing, including a warming box 1, a box door 2 is rotatably connected to one side of the warming box 1, a ventilation opening 3 is provided on one side of the warming box 1, and a plurality of support structures 4 are provided on the inner wall of the warming box 1, achieving the effect of supporting the solder paste in the warming box 1, thus minimizing the problem that when more solder paste is placed at different times and it is difficult for personnel to distinguish, resulting in a long opening time of the box door 2 and a large change in the temperature inside the warming box 1, consuming more energy. A limiting structure 5 is provided on one side of the warming box 1, achieving the effect of limiting the box door 2. By limiting the box door 2, while preventing the box door 2 from opening too large, it remains stable, thus minimizing the impact on the normal taking of solder paste by personnel.

[0030] The following specifically describes the specific settings and functions of its support structure 4 and limiting structure 5.

[0031] As Figure 1 and Figure 2 and Figure 3 shown, the support structure 4 includes two U-shaped plates 401, one side of each of the two U-shaped plates 401 is fixedly connected to the inner wall of the warming box 1, a support plate 402 is slidably connected to the inner wall of each of the two U-shaped plates 401, a rectangular frame 403 is fixedly connected to the side of the two support plates 402 close to each other, a plurality of fixing rods 404 are uniformly fixedly connected to the inner wall of the rectangular frame 403, a rotating rod 405 is rotatably connected to the arc surface of each of the plurality of fixing rods 404, a side plate 406 is fixedly connected to one side of the rectangular frame 403, a pulling plate 407 is fixedly connected to the upper surface of the side plate 406. Pulling the pulling plate 407 drives the rectangular frame 403 to move through the side plate 406, and the pulling plate 407 plays a better role in pulling the rectangular frame 403. A rotating frame 408 is fixedly connected to the upper surface of the side plate 406, a long plate 409 is rotatably connected to the surface of the rotating frame 408, label papers 410 are fixedly connected to both sides of the long plate 409, and the long plate 409 rotates to expose the label papers 410. The label papers 410 achieve the effect of quickly knowing the position of the solder paste that has not been taken out in time after the warming duration is completed. Convex plates 411 are fixedly connected to the lower surfaces of the two U-shaped plates 401, and the arc surfaces of the plurality of rotating rods 405 are slidably connected to the upper surfaces of the convex plates 411. The rectangular frame 403 drives the rotating rods 405 to slide on the upper surfaces of the convex plates 411 through the fixing rods 404, and the convex plates 411 play a role in assisting the support of the rectangular frame 403.

[0032] As Figure 4As shown in the figure, the limit structure 5 includes a long rod 51. One end of the long rod 51 is fixedly connected to the warming box 1. A circular tube 52 is rotatably connected to the arc surface of the long rod 51. A U-shaped rod 53 is fixedly connected to the arc surface of the circular tube 52. An L-shaped plate 54 is fixedly connected to one side of the box door 2. The arc surface of the U-shaped rod 53 is slidably connected to the inner wall of the L-shaped plate 54. A positioning block 55 is fixedly connected to one side of the warming box 1. One side of the positioning block 55 abuts against the short arm of the L-shaped plate 54. The rotation of the box door 2 drives the short arm of the L-shaped plate 54 to fit with the positioning block 55. The positioning block 55 plays a role in positioning the rotation angle of the box door 2. A pull rope 56 is fixedly connected to the arc surface of the U-shaped rod 53. The other end of the pull rope 56 is fixedly connected to a pull rod 58. Two circular rings 57 are fixedly connected to one side of the warming box 1. The arc surface of the pull rope 56 is slidably connected to the inner wall of the circular ring 57. The pull rod 58 drives the U-shaped rod 53 to slide out of the circular ring 57 by means of the pull rope 56. The pull rope 56 achieves the effect of quickly separating the U-shaped rod 53 from the L-shaped plate 54 on the other side of the box door 2.

[0033] Working principle: When processing is required with solder paste, first open the box door 2 and limit it through the limit structure 5. Then pull the pull plate 407 to the side away from the warming box 1. The side plate 406 drives the rectangular frame 403 to move through the pull plate 407. The support plate 402 slides in the U-shaped plate 401 through the rectangular frame 403. The fixed rod 404 drives the rotating rod 405 to slide on the upper surface of the convex plate 411 through the rectangular frame 403. The convex plate 411 plays a role in assisting the support of the rectangular frame 403. Until the rectangular frame 403 is pulled out to a certain distance, place the refrigerated solder paste in the rectangular frame 403. The solder paste slides on the arc surface of the rotating rod 405, so that the solder paste moves to the inside of the rectangular frame 403 through the sliding of the rotating rod 405. After placing the solder paste one after another, rotate the long plate 409 through the rotating frame 408. At this time, the label paper 410 shows the warming state through the rotation of the long plate 409. The label paper 410 achieves the effect of quickly knowing the position where the solder paste has not been taken out in time after the warming time is completed. Then, drive the rectangular frame 403 into the warming box 1 again through the pull plate 407 with the help of the side plate 406. Finally, close the box door 2. After warming for three to four hours, open the box door 2 and pull out the rectangular frame 403 through the pull plate 407. The pull plate 407 plays a better role in pulling the rectangular frame 403. Through the classification of multiple rectangular frames 403 and the identification of the label paper 410, personnel can quickly pick up, thereby reducing the opening time of the box door 2, reducing the temperature difference change in the warming box 1, and then keeping the warming box 1 as close to a constant temperature as possible to improve the overall energy efficiency.

[0034] When it is necessary to limit the opening of the rear box door 2, first pull the pull rope 56 with the help of the pull rod 58. The pull rope 56 slides within the circular ring 57. The U-shaped rod 53 drives the circular tube 52 to rotate from the arc surface of the long rod 51 through the pulling of the pull rope 56. Subsequently, rotate the box door 2. After the short arm of the L-shaped plate 54 fits with the positioning block 55 through the rotation of the box door 2, the positioning block 55 plays a role in positioning the rotation angle of the box door 2. Release the pull rod 58. At this time, the U-shaped rod 53 drops due to its own gravity, and the pull rope 56 slides within the circular ring 57 through the U-shaped rod 53, achieving the effect that the pull rope 56 can also quickly separate the U-shaped rod 53 from the L-shaped plate 54 on the other side of the box door 2. The U-shaped rod 53 then drives the circular tube 52 to rotate through the long rod 51 and finally rotates into the L-shaped plate 54. The box door 2 is limited and cannot move due to the blockage of the U-shaped rod 53.
