[0021] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0022] The oven of the present invention will be described below with reference to the accompanying drawings.

[0023] like Figure 1 and Figure 2As shown, the utility model provides an oven, which includes a frame 10, a baking tray lifting mechanism and a transfer mechanism 30. The frame 10 is provided with an oven body 11. The baking tray lifting mechanism includes at least two groups of adjustment components 20 arranged in the oven body 11, and at least two groups of adjustment components 20 include lifting ends that can be adjusted up and down; the transfer mechanism 30 includes an externally controlled transfer robot 31 and an externally controlled opening and closing component 32. The externally controlled transfer robot 31 is movably arranged above two adjacent groups of adjustment components 20; the externally controlled opening and closing component 32 is arranged above the externally controlled transfer robot 31, and control structures 321 that can be adjusted up and down are correspondingly arranged at the two ends of the moving stroke of the externally controlled transfer robot 31.

[0024] Specifically, a furnace body 11 is provided on the frame 10, and at least two groups of adjusting components 20 are provided in the furnace body 11. Each group of adjusting components 20 can accommodate multiple baking trays 200 for vertical spacing and can drive the multiple baking trays 200 to rise and fall synchronously, and each baking tray 200 can be used to hold glass. The transfer mechanism 30 is provided at the top of the furnace body 11. After one group of adjusting components 20 drives the baking tray 200 to rise to the top, one of the control structures 321 can drive the externally controlled transfer robot 31 to clamp the baking tray 200, so that the externally controlled transfer robot 31 transfers the baking tray 200 from one group of adjusting components 20 to another group of adjusting components 20, and the other control structure 321 drives the externally controlled transfer robot 31 to relax the baking tray 200 so that the other group of adjusting components 20 drives the baking tray 200 to descend, so that multiple baking trays 200 are vertically spaced on each group of adjusting components 20, so that multiple baking trays 200 can be baked synchronously, the baking efficiency is high, and the oven occupies a small area and has high space utilization.

[0025] Furthermore, if Figure 1 and Figure 2 As shown, two furnace cavities 111 for baking glass are provided in the furnace body 11, and the two furnace cavities 111 are arranged adjacent to each other, and the baking tray lifting mechanism includes two groups of adjustment components 20 arranged in the two furnace cavities 111, and the two groups of adjustment components 20 can respectively drive the baking tray 200 to rise and fall, and the externally controlled transfer manipulator 31 is movably arranged at the top of the two furnace cavities 111, one group of adjustment components 20 drives the baking tray 200 to rise to the top of the corresponding furnace cavity 111, and the externally controlled transfer manipulator 31 transfers the baking tray 200 to the top of the other furnace cavity 111, and the other group of adjustment components 20 drives the baking tray 200 to descend to the bottom of the corresponding furnace cavity 111, so that multiple baking trays 200 are vertically placed in the two furnace cavities 111, thereby improving the baking efficiency.

[0026] It is understandable that the number of furnace chambers 111 in the furnace body 11 can be set to one or more than two, and its function can include baking glass here, and can also be used for other purposes (such as temporary storage). Overall, as long as it can meet actual production needs, its arrangement form and set number can be adjusted.

[0027] In an embodiment of the utility model, a feed port and a discharge port are respectively provided on both sides of the furnace body 11, and both the feed port and the discharge port are close to the corresponding adjustment assembly 20; the oven also includes a conveying mechanism 40 arranged on the frame 10, and the conveying mechanism 40 has a plurality of conveying parts, each conveying part acts between the feed port or the discharge port and the corresponding adjustment assembly 20.

[0028] like Figure 1 As shown, the conveying mechanism 40 is arranged on the frame 10 and has a conveying part for conveying the baking tray 200. The feed port and the discharge port are respectively connected to the two oven cavities 111 in a one-to-one correspondence. The conveying mechanism 40 can convey the baking tray 200 from the feed port to one of the oven cavities 111, and can convey the baking tray 200 in the other oven cavity 111 to the outside of the oven body 11 from the discharge port; specifically, the conveying part of the conveying mechanism 40 can transport the unbaked baking tray 200 to one of the oven cavities 111, so that one set of adjustment components 20 drives the baking tray 200 to rise to the top of the oven cavity 111, and the outside The controlled transfer robot 31 transfers the baking tray 200 to another furnace cavity 111, so that another set of adjusting components 20 drives the baking tray 200 to descend to the bottom of the furnace cavity 111. After the two furnace cavities 111 are filled with baking trays 200, the glass on multiple baking trays 200 is baked synchronously. After baking is completed, the conveying part of the conveying mechanism 40 transports the baking tray 200 from the discharge port to the outside of the furnace body 11 to complete the baking of the glass. Multiple baking trays 200 can be placed vertically in the furnace cavity 111 and driven to rise and fall by the adjusting component 20, which has the advantages of high baking efficiency and small oven footprint.

[0029] Furthermore, the oven further comprises a cooling mechanism 50 disposed at the discharge port, and the cooling mechanism 50 has a cooling channel adapted to the conveying portion. Figure 1 As shown, the cooling channel is connected to one of the conveying parts and is used for the baking tray 200 to pass through. The conveying part of the conveying mechanism 40 can convey the baking tray 200 from the discharge port to the cooling channel and convey it along the extension direction of the cooling channel. After the baking tray 200 in the furnace cavity 111 is baked, the conveying mechanism 40 can transport the baking tray 200 from the discharge port to the cooling channel. The cooling mechanism 50 cools the glass on the baking tray 200 to achieve rapid cooling of the glass, thereby further improving production efficiency.

[0030] In the embodiment of the utility model, the adjustment component 20 includes a lifting clamping structure 21 and a buffer clamping structure 22. The lifting clamping structure 21 and the buffer clamping structure 22 both have a clamping state and a relaxing state and operate alternately. The lifting clamping structure 21 can be lifted and lowered between a first height position and a second height position. Specifically, when the lifting clamping structure 21 is in a relaxing state, the buffer clamping structure 22 clamps the baking tray 200; when the lifting clamping structure 21 is in a clamping state, the buffer clamping structure 22 relaxes the baking tray 200. In addition, it should be noted that the adjustment component 20 is set in two groups, and the two groups of adjustment components 20 are respectively arranged in two oven cavities 111. The number of lifting clamping structures 21 and buffer clamping structures 22 in each group of adjustment components 20 can be one or more, and the number of lifting clamping structures 21 and buffer clamping structures 22 in each group of adjustment components 20 is consistent and arranged in one-to-one correspondence.

[0031] like Figures 2 to 5 As shown, the lifting and clamping structure 21 and the buffer clamping structure 22 are staggered in the oven cavity 111, and the lifting and clamping structure 21 and the buffer clamping structure 22 can synchronously clamp a plurality of vertically spaced baking trays 200, the conveying mechanism 40 transports the baking tray 200 from the feed port to the oven cavity 111, so that the lifting and clamping structure 21 clamps the baking tray 200 and drives the baking tray 200 to rise from a first height position to a second height position, the lifting and clamping structure 21 releases the baking tray 200 at the second height position, so that the buffer clamping structure 22 clamps the baking tray 200 at the second height position, the lifting and clamping structure 21 descends to the first height position and clamps the baking tray 200 again, the buffer clamping structure 22 is released after the lifting and clamping structure 21 clamps the baking tray 200, so that the lifting and clamping structure 21 The structure 21 drives the baking tray 200 to rise in the oven cavity 111 again, and the lifting and clamping structure 21 and the cache clamping structure 22 operate alternately to allow multiple baking trays 200 to be placed vertically at intervals in the oven cavity 111; it can be understood that after the baking trays 200 in one of the oven cavities 111 are full, the externally controlled transfer robot 31 transfers the baking tray 200 to another oven cavity 111, and the lifting and clamping structure 21 in the other oven cavity 111 reciprocates to drive the baking tray 200 to descend from the second height position to the first height position, and operates alternately with the cache clamping structure 22 until the baking trays 200 in the two oven cavities 111 are full, and then the baking trays 200 in the two oven cavities 111 can be baked synchronously, with high baking efficiency, small oven footprint, and high space utilization.

[0032] In an embodiment of the utility model, the lifting and clamping structure 21 includes a lifting plate 211, a lifting drive member 212, a first translation drive member 213 and two groups of first sub-plate sheet metals 214. The lifting drive member 212 is transmission-connected to the lifting plate 211 and can drive the lifting plate 211 to lift and lower between a first height position and a second height position. The two groups of first sub-plate sheet metals 214 are movably arranged on the lifting plate 211 and are transmission-connected to the first translation drive member 213 so as to move closer to each other for clamping or away from each other. That is, the first translation drive member 213 can drive the two groups of first sub-plate sheet metals 214 to move closer to each other for clamping the baking tray 200 or away from each other to release the baking tray 200. In addition, it should be noted that the first sub-plate sheet metal 214 is provided in two groups, and the two groups of first sub-plate sheet metal 214 are respectively provided at both ends of the baking tray 200. The number of the first sub-plate sheet metal 214 in each group can be one or more, and the number of the first sub-plate sheet metal 214 in the two groups can be the same or different. The two groups of first sub-plate sheet metal 214 can cooperate to clamp the baking tray 200 from both ends of the baking tray 200.

[0033] like Figures 2 to 5 As shown, the two groups of first plate sheet metals 214 are symmetrically arranged on the lifting plate 211 and are movable. The first translation driving member 213 can drive the two groups of first plate sheet metals 214 to move toward each other, so that the two groups of first plate sheet metals 214 cooperate to clamp the baking tray 200. The lifting driving member 212 can drive the lifting plate 211 to rise and fall in the oven cavity 111, so that the lifting plate 211 drives the two groups of first plate sheet metals 214 and the baking tray 200 to rise and fall. When the lifting plate 211 drives the baking tray 200 to rise to the second highest position, the lifting plate 211 can move the two groups of first plate sheet metals 214 and the baking tray 200 to rise and fall. After the baking tray 200 is raised to the first height position or drops to the first height position, the first translation drive member 213 drives the two groups of first sub-plate sheet metals 214 to move oppositely to loosen the baking tray 200, so that the cache clamping structure 22 clamps the baking tray 200, and the lifting drive member 212 drives the lifting plate 211 to reset and clamp the baking tray 200 again to drive the baking tray 200 to rise and fall, and the lifting clamping structure 21 and the cache clamping structure 22 operate alternately so that a plurality of baking trays 200 can be synchronously placed vertically at intervals in the oven cavity 111, thereby reducing the floor space.

[0034] Furthermore, a plurality of vertically arranged first clamping grooves 215 are formed on the first plate sheet metal 214, and the size of the first clamping grooves 215 is gradually expanded from the inside to the outside. Figure 6As shown, the first clamping groove 215 is used for the edge of the baking tray 200 to extend into, and the two groups of first sub-plate sheet metals 214 move toward each other, so that the two symmetrically arranged first clamping grooves 215 cooperate to clamp the baking tray 200, and the clamping is stable and reliable, which effectively prevents the baking tray 200 from falling into the oven cavity 111 and getting stuck. Moreover, the size of the first clamping groove 215 is gradually expanded from the bottom of the groove toward the groove mouth. Even if the baking tray 200 is deformed, the first clamping groove 215 can still allow the baking tray 200 to extend into and support the baking tray 200, which greatly reduces the risk of getting stuck. Moreover, the multiple first clamping grooves 215 are vertically arranged in sequence in a serrated shape to achieve synchronous clamping of multiple baking trays 200. In addition, the first sub-plate sheet metal 214 can be made of stainless steel, which has the advantages of high strength and good high temperature resistance.
