This device increases the number of products processed at one time, improves product manufacturing efficiency, and eliminates the product scratching phenomenon during the original blue adhesive and carbon ink product processing. The number of layers of the transfer cart can be freely set, which can meet the processing needs of blue adhesive and carbon ink products for small PCBs after the PCB outline. This device is made of stainless steel and does not deform during use, significantly reducing product processing costs. It can realize the processing of small PCS products after the PCB outline, realizing the production of multiple PCS at one time.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0025] Please see Figures 1-6 The present invention provides the following technical solution: a carbon oil baking device, which includes a baking machine 1 positioned and assembled on the ground, and a positioning base plate 2 is nested and connected to the lower side of the inner surface of the baking machine 1, and a movable frame 3 is limited and connected to the upper surface of the positioning base plate 2.

[0026] Example 1: As Figures 1-4 The technical solution shown is provided by this utility model as follows: A carbon oil baking device, comprising: a nesting block 4, installed on the rear side of the inner surface of a movable frame 3, and a tray 5 nested on the outer surface of the nesting block 4, which is placed on the movable frame 3; a handle groove 6 is provided on the front side of the outer surface of the movable frame 3; and the movable frame 3 is provided with a limit locking mechanism. Please refer to [link to relevant documentation]. Figure 3 The movable frame 3 forms a limiting support structure with the tray 5 through the nested block 4, and the tray 5 is evenly spaced with respect to the inner surface of the movable frame 3. Furthermore, the handle groove 6 provided in the movable frame 3 facilitates the placement and removal of the tray 5. Figure 3 and Figure 4 As shown, the limiting engagement mechanism includes a take-up roller 7 rotatably connected to the right side of the inner surface of the movable frame 3, and a pull rope 8 is installed on the outer surface of the take-up roller 7. A locking member 9 is installed at the end of the outer surface of the pull rope 8. A tray 5 is engaged with the outer surface of the locking member 9, and a pressing block 10 is installed on the outer surface of the locking member 9. A return spring 11 is elastically connected between the pressing block 10 and the movable frame 3. Figure 3 and Figure 4 As shown, the movable frame 3 and the take-up roller 7 form a rotating structure, and the take-up roller 7 forms a pulling and sliding structure with the pull rope 8 and the clamp 9. The clamp 9 forms a limiting and engaging structure with the tray 5. At the same time, the clamp 9 forms an elastic reset structure with the movable frame 3 through the squeezing block 10 and the reset spring 11.

[0027] In use, the nesting block 4, assembled via the movable frame 3, nests and positions the rear side of the tray 5 when it is placed. This provides support to the movable frame 3 and increases rear-side stability. It also works in conjunction with the pressing block 10 connected to the front return spring 11 of the movable frame 3. The clamping piece 9 installed on the pressing block 10 engages with the clamping piece 9 when the tray 5 is placed on top, controlling the positioning stability of the tray 5 and preventing it from moving. After assembling multiple trays 5 onto the movable frame 3, the movable frame 3 is pushed to cooperate... The groove of the positioning base plate 2 assembled in the baking machine 1 improves the bottom limit stability when the moving frame 3 moves into the baking machine 1. When the baking machine 1 finishes working and the moving frame 3 is pulled to discharge the material and the tray 5 is to be removed, the handle groove 6 opened in the moving frame 3 is used to pick up the side of the tray 5. The winding roller 7 drives the locking piece 9 connected to the pull rope 8 to slide in the center, which can drive the locking piece 9 to disengage from the tray 5, thereby removing the tray 5 and taking out the product with carbon oil, thus improving the convenience of picking up and putting away the carbon oil tray 5.

[0028] Example 2: Figure 1 and Figure 5 The technical solution shown, based on Embodiment 1, further discloses the stability of the top of the movable rack 3 during the baking process, improving stability and facilitating automatic clamping and limiting, thus solving the problem of shaking of the carbon oil product in the top tray 5. The specific details are as follows: An inclined brace 12 is attached to the inner surface sidewall of the baking machine 1, and a slider 13 is rotatably connected to the front end of the outer surface of the inclined brace 12. A sliding pad 14 is slidably connected to the outer surface of the slider 13, and the sliding pad 14 is nested within the inner surface of the baking machine 1. Simultaneously, the slider 13 is controlled to slide on the inner surface sidewall of the baking machine 1. The inclined brace 12 is also equipped with an elastic compression mechanism. Figure 5 As shown, the diagonal brace 12 forms a nested sliding structure with the baking machine 1 via the slider 13 and the sliding pad 14, and the sliding pad 14 forms an internal structure with the baking machine 1. The sliding pad 14 is used to increase the sliding efficiency of the slider 13 and prevent jamming. Figure 5As shown, the elastic extrusion mechanism includes an extrusion plate 15 rotatably connected to the rear side of the outer surface of the diagonal brace 12, and a roller 16 rotatably connected to the inner surface of the extrusion plate 15. A movable frame 3 is attached to the outer surface of the roller 16. A telescopic rod 17 is installed on the outer surface of the extrusion plate 15, and a telescopic assembly 18 is telescopically connected to the outer surface of the telescopic rod 17. The telescopic assembly 18 is installed on the inner side wall of the baking machine 1, and a compression spring 19 is nested on the outer surfaces of the telescopic assembly 18 and the telescopic rod 17. The diagonal brace 12 and the extrusion plate 15 form a rotating structure, and the extrusion plate 15 forms a rolling extrusion mechanism with the movable frame 3 through the roller 16. The extrusion plate 15 forms an elastic telescopic structure with the baking machine 1 through the telescopic rod 17, the telescopic assembly 18, and the compression spring 19. At the same time, the telescopic rod 17, the telescopic assembly 18, and the compression spring 19 form a through-nested structure.

[0029] When the movable frame 3 is pushed into the baking machine 1, the side of the movable frame 3 is pressed against the inclined support 12. The inclined support 12 follows the pressing force, causing the slider 13 connected to the inclined support 12 to slide within the sliding pad 14 nested in the baking machine 1. This controls the sliding stability of the front side of the inclined support 12, preventing jamming. Simultaneously, the pressing plate 15 rotatably connected to the rear side of the inclined support 12 and the telescopic rod 17 installed on the pressing plate 15 slide within the telescopic assembly 18 installed in the baking machine 1. Simultaneously, the pressing spring 19 nested and passing through the outer side of the telescopic assembly 18 and the telescopic rod 17 retracts, causing the movable frame 3 to move stably into the baking machine 1. The top of the movable frame 3 is centered and limited by the pressing plate 15 elastically controlled by the baking machine 1, preventing the top of the movable frame 3 from shaking during hot air baking. This also controls the baking stability of the carbon oil coated on the product in the tray 5. As the movable frame 3 moves into the baking machine 1, the rollers 16 nested in the inclined support 12 and the pressing plate 15 simultaneously reduce friction damage to the movable frame 3 and improve its service life.

[0030] Example 3: Figure 1 and Figure 6 The technical solution shown, based on Embodiment 2, further discloses the efficiency of hot air baking, improves the speed of hot air delivery, increases the temperature rise rate, and solves the problem of slow temperature rise. The specific content is as follows: A heating frame 20 is nested on the lower rear side of the inner surface of the baking machine 1, and a heating wire 21 is nested on the inner surface of the heating frame 20. A heating ratchet 22 is nested on the outer surface of the heating wire 21. At the same time, a circulating fan 23 is installed on the front side of the outer surface of the heating frame 20, and the circulating fan 23 is located behind the moving frame 3. The heating ratchet 22 is equidistant from the inner surface of the heating frame 20 to increase the release of heat.

[0031] When the moving frame 3 is transported into the baking machine 1 and the cabinet door is closed, the heating wire 21 on the control heating frame 20 is started, and the circulating fan 23 is started simultaneously. The heat generated by the heating wire 21 is transferred to the heating fins 22, which can quickly circulate the heat in the baking machine 1, increase the speed of hot air blowing, and is nested and assembled in the middle and lower part of the baking machine 1 with the heating frame 20, and is symmetrically arranged. The outer side of the heating frame 20 is hollowed out to improve the air intake efficiency.

[0032] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
