The present utility model will be further described with reference to the accompanying drawings and embodiments:

[0032] like Figures 1 to 4 As shown, a support device for heat treatment of glass insulators includes a ring chain conveyor 1 (which is prior art and its principle is not described), a heating channel 2, an inlet 21, an outlet 22, a constant temperature heating element 23, a rotating assembly, a support frame 6, a placement plate 7, support bars 8, and limiting holes 9.

[0033] The heating channels 2 are symmetrically arranged on the ring chain conveyor 1, and the heating channels 2 have an inlet 21 and an outlet 22 at both ends respectively;

[0034] Several constant-temperature heating elements 23 are arranged along the length of the inner wall of the heating channel 2;

[0035] The rotating component is mounted on the conveyor chain plate 11 of the ring chain machine 1 and the rotating component is connected to the support frame 6 (more precisely, there is an empty conveyor chain plate 11 between the conveyor chain plates 11 where two adjacent support frames 6 are located).

[0036] The placement plate 7 is connected to the support frame 6, and the placement plate 7 has several spaced support bars 8 arranged around its circumference;

[0037] The support bar 8 is integrally formed and includes a horizontal part and a curved part;

[0038] The limiting hole 9 is located in the center of the placement plate 7 and is adapted to the size of the glass part head.

[0039] Further refinements of the embodiments of this utility model, such as... Figure 2 As shown, the rotating assembly includes a connecting roller 3, a gear transmission assembly 4, and a mounting plate 5. The connecting roller 3 passes through the conveyor chain plate 11 and is rotatably connected to the conveyor chain plate 11. The gear transmission assembly 4 is fixed on the bottom surface of the conveyor chain plate 11 and connected to the connecting roller 3. The end of the connecting roller 3 away from the gear transmission assembly 4 is fixedly provided with the mounting plate 5, and a support frame 6 is welded on the mounting plate 5.

[0040] In a further refinement of the embodiment of this utility model, a six-degree-of-freedom robotic arm is fitted on one side of the arc segment of the ring chain machine 1. The six-degree-of-freedom robotic arm is connected to a flexible clamp. The six-degree-of-freedom robotic arm and the flexible clamp are not shown in the figure.

[0041] In a further refinement of the embodiment of this utility model, a heat insulation plate is provided on the inner wall of the heating channel 2, and a constant temperature heating element 23 is provided on the heat insulation plate. The heat insulation plate is not shown in the figure.

[0042] It should be noted that the ring chain conveyor 1, the constant temperature heating element 23, and the gear transmission assembly 4 are all electrically connected to the controller, which is not shown in the figure.

[0043] The working process of this utility model is as follows:

[0044] First, a glass piece (not shown in the figure) can be placed on one of the placement plates 7 using a six-degree-of-freedom robotic arm and a flexible clamp. During the placement process, the head of the glass piece passes through the limiting hole 9, and then several support bars 8 come into contact with the glass piece, which can reduce the phenomenon of large-area heat absorption of the support frame 6 during the subsequent heating process. At the same time, the arc part of the support bar 8 fits with the glass piece, which can limit the placement area of ​​the glass piece. After a glass piece is placed, the controller controls the ring chain conveyor 1 to move, which can then transport the glass piece into the heating channel 2. At the same time, the controller controls the gear transmission assembly 4 to operate, which can make the glass piece on the support frame 6 rotate slowly and uniformly. The rotation speed of the support frame 6 is preset and will not cause the glass piece to fall off.

[0045] The above process is repeated to continue to place the glass piece on the next adjacent support frame 6, and the interval of one empty conveying chain plate 11 between the two adjacent support frames 6 is to give sufficient material taking and placing time, so that the ring chain plate machine 1 does not need to stop working, and then the first placed glass piece can enter from the heated channel 2 inlet 21 on one side, and the constant temperature heating piece 23 is turned on in advance before the glass piece enters, and the temperature is raised to the pre-set temperature range and the temperature value is maintained, and then the glass piece can rotate in the heated channel 2 during heat treatment, thereby being heated sufficiently to solve the problem of uneven heating during high-temperature pressing. The layout length of one heated channel 2 is 7-8M, so that the heating time of the glass piece is sufficient, and then the glass piece is moved to the initial feeding position after being heated evenly in the two heated channels 2. At this time, the glass piece is unloaded by the six-degree-of-freedom mechanical arm cooperating with the flexible clamp for subsequent tempering and air cooling process. In this way, the probability of self-explosion of the glass piece in the subsequent tempering process due to uneven heating of the surface of the glass piece after demolding can be greatly reduced, the safety is improved, and the processing qualified rate of the glass piece is improved.

[0046] When the unloading of the glass piece on one support frame 6 is completed, a newly demolded glass piece can be placed again for a new round of heat treatment, and the subsequent glass pieces are unloaded in turn after the above process.

[0047] Compared with the prior art, the device can realize the assembly line heat treatment of the demolded glass piece, effectively support the glass piece during heat treatment and make it rotate to make the surface of the glass piece heat evenly, and the probability of self-explosion of the glass piece can be significantly reduced after the tempering process, the safety of the glass piece during processing and the qualified rate after processing are significantly improved.

[0048] In some embodiments, a plurality of flow-through holes are provided on the support strip 8 and sequentially penetrate the support strip 8 and the placing plate 7, and the flow-through holes are not shown in the figure. In this embodiment, the flow-through holes can make the glass piece heat more evenly during heat treatment, and the heat treatment effect is further improved.

Those skilled in the art should understand that the present application is not limited to the above embodiments, and the above embodiments and descriptions in the specification are only to illustrate the principles of the present application.
