[0037] Referring to Figure 1 and Figure 2 In some embodiments, the present application provides a brittle material heating device, comprising:

[0038] a mounting seat 1;

[0039] an upper jig 2 and a lower jig 3, the upper jig 2 and the lower jig 3 are spaced apart in a vertical direction on the mounting seat 1, and a channel for passing brittle material is formed between the upper jig 2 and the lower jig 3;

[0040] a conveying mechanism 4 provided on the mounting seat 1, for conveying brittle material to the channel;

[0041] a driving mechanism 5 provided on the mounting seat 1, an output end of the driving mechanism 5 is connected to at least one of the upper jig 2 and the lower jig 3, for driving the upper jig 2 and the lower jig 3 to hold the brittle material in the channel;

[0042] a heating element 6 provided on the upper jig 2 and the lower jig 3, for heating the upper jig 2 and the lower jig 3 to heat the brittle material held by the upper jig 2 and the lower jig 3.

[0043] In the present embodiment, the brittle material heating device of the present application mainly uses the principle of direct contact heat conduction to heat the brittle material. First, the brittle material is sent into the channel formed between the upper jig 2 and the lower jig 3 by the conveying mechanism 4, the heating element 6 is installed on the upper jig 2 and the lower jig 3, when the heating element 6 works, the heat is transferred to the upper jig 2 and the lower jig 3, then the upper jig 2 and the lower jig 3 are made to hold the brittle material in the channel by the driving mechanism 5, the upper jig 2 and the lower jig 3 are in close contact with the brittle material, and the heat is conducted from the jig to the brittle material, thereby realizing the heating of the brittle material.

[0044] By setting the brittle material heating device, the brittle material can be effectively heated in contact, and the uniformity of heating can be ensured by the upper jig 2 and the lower jig 3 simultaneously supporting the brittle material. Because heat is transmitted to the brittle material from the upper and lower directions at the same time, compared with unilateral heating, the temperature gradient can be reduced, and the temperature distribution in the material is more uniform. And through the cooperation of the conveying mechanism 4 and the driving mechanism 5, the continuous heating treatment of the brittle material can be realized. For example, in industrial production, the unheated brittle material can be continuously conveyed into the channel, and then output after heating, thereby improving the production efficiency.

[0045] In some embodiments, during the process of supporting the brittle material, the pressure of the driving mechanism 5 can be controlled to avoid damage to the brittle material due to excessive extrusion, while ensuring sufficient contact pressure to effectively conduct heat.

[0046] Referring to Figure 1 and Figure 2 In some embodiments, the conveying mechanism 4 provided by the utility model embodiment comprises:

[0047] A plurality of conveying rollers 41 are rotatably arranged on the mounting base 1, and each conveying roller 41 is horizontally spaced apart.

[0048] A conveying driving member 42 is arranged on the mounting base 1, and the output end of the conveying driving member 42 is in transmission connection with each conveying roller 41, so as to drive each conveying roller 41 to rotate.

[0049] In the embodiment, the conveying driving member 42 serves as a power source, and the output end of the conveying driving member 42 is in transmission connection with each conveying roller 41. When the conveying driving member 42 is started, it transmits power to the conveying roller 41, so that the conveying roller 41 starts to rotate. The brittle material can be placed on the conveying roller 41, and there is a friction force between the surface of the conveying roller 41 and the brittle material. During the continuous rotation of the conveying roller 41, the friction force pushes the brittle material to move along the arrangement direction of the conveying roller 41, so as to achieve the purpose of conveying the brittle material to the specified position (i.e. the channel between the upper jig 2 and the lower jig 3).

[0050] Firstly, when the entire brittle material heating device is started, the conveying driving member 42 starts to work. The output shaft of the conveying driving member 42 rotates, and power is transmitted to each horizontally spaced conveying roller 41 through a transmission device (such as a chain, a belt or a gear, etc.).

[0051] Then, the operator places the brittle material on the conveying roller 41 at the starting position. With the continuous rotation of the conveying roller 41, the brittle material starts to move forward under the action of the friction force. During the movement, because each conveying roller 41 is horizontally spaced apart and rotates synchronously, the brittle material can smoothly advance on the conveying roller 41.

[0052] Finally, the brittle material is transported into the channel formed between the upper jig 2 and the lower jig 3, the transportation process is completed, and the subsequent heating process is waited.

[0053] The brittle material transportation operation is realized automatically by the transportation mechanism 4 with the above structure, and the work efficiency is high.

[0054] Please continue to refer to Figure 1 and Figure 2 In some embodiments, the plurality of conveying rollers 41 proposed in the embodiments of the utility model comprises:

[0055] The feeding roller 411 and the discharging roller 412 are respectively located at the first end and the last end of the transportation mechanism 4.

[0056] In the embodiment, the main function of the feeding roller 411 is to realize the smooth and accurate entry of the brittle material into the transportation mechanism 4, which is the starting link of the brittle material into the entire heating process, and lays the foundation for the subsequent transportation and heating processes. The operator places the brittle material on the feeding roller 411, and the rotation of the feeding roller 411 can introduce the brittle material into the main conveying path of the transportation mechanism 4, ensuring that the material smoothly enters the working area of the brittle material heating device.

[0057] The function of the discharging roller 412 is to smoothly output the brittle material that has completed the heating treatment from the transportation mechanism 4. It ensures that the heated brittle material can orderly leave the heating device for subsequent processing, detection or storage operations. The setting of the discharging roller 412 ensures the continuity of the entire heating process, so that the product can smoothly transition from the heating link to the next production link.

[0058] Please continue to refer to Figure 1 and Figure 2 In some embodiments, the plurality of conveying rollers 41 proposed in the embodiments of the utility model further comprises at least one intermediate roller 413, the lower jig 3 is provided with a plurality of through holes, each through hole corresponds to the setting of one intermediate roller 413, the intermediate roller 413 can be accommodated in the through hole, and part of the intermediate roller 413 is located between the upper jig 2 and the lower jig 3 to carry the brittle material.

[0059] In this embodiment, during the conveying of the brittle material, the brittle material can be displaced or deformed due to its own weight or vibration during the conveying process. The intermediate roller 413 can provide an additional support point for the brittle material between the feeding roller 411 and the discharging roller 412. By being arranged through the through hole of the lower jig 3, part of the intermediate roller 413 can be exposed to the upper surface of the lower jig 3, which can effectively support the brittle material and ensure that the material remains stable during the conveying process. In particular, for brittle materials with large size or texture, the support effect is more critical. During the conveying process, the feeding roller 411, the intermediate roller 413 and the discharging roller 412 can work cooperatively under the unified driving of the conveying driving member 42. The conveying driving member 42 ensures that the rotation speed and direction of each roller are consistent through the transmission device, so as to realize the continuous and stable conveying of the brittle material.

[0060] With reference to Figure 1 and Figure 2 In some embodiments, the brittle material heating device provided by the embodiments of the present application further comprises a transmission mechanism 8 connected to the output end of the conveying driving member 42 and each conveying roller 41. The transmission mechanism 8 comprises:

[0061] a transmission rod 81 arranged in the mounting seat 1 and transmissionally connected to each conveying roller 41;

[0062] a driving wheel 82 connected to the output end of the conveying driving member 42;

[0063] a driven wheel 83 sleeved on the transmission rod 81;

[0064] a synchronous belt 84 sleeved on and meshingly connected to the driving wheel 82 and the driven wheel 83.

[0065] In the embodiment, after the conveying driving member 42 is started, the output end drives the driving wheel 82 to rotate. Since the driving wheel 82 is in engagement with the synchronous belt 84, the rotating movement of the driving wheel 82 is transmitted to the synchronous belt 84 through the engagement of the teeth of the driving wheel 82 and the tooth grooves of the synchronous belt 84, so that the synchronous belt 84 generates linear movement. The synchronous belt 84 is in engagement with the driven wheel 83, so that the movement is transmitted to the driven wheel 83, and the driven wheel 83 is driven to rotate. Since the driven wheel 83 is sleeved on the transmission rod 81, the rotation of the driven wheel 83 drives the transmission rod 81 to rotate. The transmission rod 81 is in transmission connection with each conveying roller 41, and finally the movement is transmitted to each conveying roller 41 in sequence, so that the conveying rollers 41 rotate in the same direction and at a certain speed, and the brittle material is conveyed. Through the engagement of the synchronous belt 84 with the driving wheel 82 and the driven wheel 83, and the connection of the transmission rod 81 with each conveying roller 41, the rotating speeds of the conveying rollers 41 are highly consistent. The problems of material distortion, jamming and even damage caused by inconsistent rotating speeds of the rollers are avoided. Moreover, the synchronous belt 84 has high transmission efficiency, and can transmit the power of the conveying driving member 42 to each conveying roller 41 more completely, so that the energy loss is reduced. Moreover, the transmission mode has relatively simple structure, and is convenient to install and maintain, so that the operation cost and maintenance difficulty of the equipment are reduced.

[0066] With reference to Figure 1 and Figure 2 In some embodiments, the lower jig 3 is slidably connected to the mounting seat 1, and the output end of the driving mechanism 5 is connected to the lower jig 3 to drive the lower jig 3 to approach or move away from the upper jig 2 in the vertical direction.

[0067] In the embodiment, when the conveying mechanism 4 conveys the brittle material to the passage between the upper jig 2 and the lower jig 3, the driving mechanism 5 starts to act, and accurately controls the lower jig 3 to approach the upper jig 2 in the vertical direction until the upper jig 2 and the lower jig 3 clamp the brittle material and heat the brittle material.

[0068] In some embodiments, as described in the foregoing embodiments, when the driving mechanism 5 drives the lower jig 3 to move towards the upper jig 2, the intermediate roller 413 remains stationary, and the lower jig 3 continuously rises to receive the brittle material on the lower jig 3. At this time, the intermediate roller 413 is not exposed to the through hole, that is, not exposed between the upper jig 2 and the lower jig 3, the lower jig 3 receives and drives the brittle material to move upwards and abut against the upper jig 2, and at this time, the upper jig 2 and the lower jig 3 clamp the brittle material in the passage.

[0069] With reference to Figure 1 and Figure 2 In some embodiments, the upper jig 2 and the lower jig 3 are both provided with at least one receiving hole for receiving the heating member 6.

[0070] In this embodiment, the setting of the accommodating hole serves to provide a stable mounting position for the heating element 6, ensure that it does not displace during operation, and ensure that heat is uniformly and stably transmitted to the jig, thereby avoiding uneven heating or damage to components due to shaking. The accommodating hole connects the heating element 6 to the jig, reduces thermal resistance, efficiently transmits heat, increases the contact area through the jig, allows heat to be quickly and uniformly distributed, and improves the uniformity and efficiency of heating of brittle materials.

[0071] For example, heating elements such as heating rods, heating sheets, and heating tubes can be used. A heating rod is composed of a resistance wire and an insulating material. When an electric current passes through the resistance wire, heat is generated, which is transmitted to the jig through the accommodating hole. The heating rod has the advantages of simple structure, high efficiency, and low cost, and is suitable for heating various brittle materials such as glass.

[0072] A heating sheet such as a ceramic or mica heating sheet has a thin profile and can be attached to the inner wall of the accommodating hole. It generates heat using the electrothermal effect and has a large heating area, which allows for more uniform heat transmission. It is suitable for processing brittle materials that require high uniformity of heating.

[0073] A heating tube is composed of a metal tube, a resistance wire, and an insulating material inside the tube. It is resistant to high temperatures and corrosion, can be customized according to the accommodating hole, has high heating efficiency, and can operate stably in harsh environments. It is suitable for processes that require high heating temperature and stability.

[0074] Referring to Figure 1 and Figure 2 In some embodiments, the brittle material heating device also includes a heat-conducting member 9, which is arranged on one side of the upper jig 2 facing the lower jig 3 and on one side of the lower jig 3 facing the upper jig 2.

[0075] In some embodiments, the heat-conducting member 9 is made of a flexible heat-conducting material.

[0076] In this embodiment, the heat-conducting member 9 is arranged on the opposite side of the upper jig 2 and the lower jig 3, which can serve as a conductor for heat conduction, further optimizing the heat transfer path from the heating element 6 to the brittle material. The heat generated by the heating element 6 is first transmitted to the jig, and through the heat-conducting member 9, it can be more quickly and effectively conducted to the brittle material, reducing heat loss during transmission and improving overall heating efficiency.

[0077] The heat-conducting member 9 can make the heat more uniformly distributed on the contact surface between the jig and the brittle material. Different parts of the brittle material can receive relatively consistent heat, avoiding problems such as material deformation and cracking caused by local heat concentration or deficiency, which helps to improve the quality and processing precision of the product.

[0078] In some embodiments, the use of the heat-conducting member 9 in a flexible heat-conducting material serves to provide a certain buffering effect during the clamping of the fragile material by the jig, thereby reducing the direct pressure of the jig on the fragile material and reducing the risk of material rupture due to excessive clamping force. At the same time, during heating, the flexible heat-conducting material can better adapt to such changes due to thermal expansion and contraction, thereby avoiding damage to the material due to thermal stress concentration. For example, flexible graphite sheets, heat-conducting rubber, etc. can be used. Flexible graphite sheets have extremely high thermal conductivity and are soft in texture, and can be well fitted to the surface of the fragile material. They also have good chemical stability and are not prone to chemical reactions in high-temperature environments, making them suitable for use in fragile material heating scenarios that require high temperatures. Heat-conducting rubber combines the flexibility of rubber with certain heat-conducting capabilities. It can be made into various shaped gaskets or coatings and installed on the jig. Heat-conducting rubber also has certain shock-absorbing and cushioning properties, which can effectively transfer heat while protecting the fragile material.

[0079] Referring to Figure 1 and Figure 2 In some embodiments, the fragile material heating device proposed in the embodiments of the present application further comprises a stop component 10 arranged at the end of the conveying mechanism 4. The stop component 10 comprises a stop driving member 101 arranged on the mounting seat 1 and a stop piece 102 arranged at the output end of the stop driving member 101. The stop driving member 101 is used to drive the stop piece 102 to move in the vertical direction, so as to block the horizontal movement of the fragile material in the channel.

[0080] In this embodiment, when the conveying mechanism 4 conveys the fragile material close to the end of the channel, the stop driving member 101 can be started by the control system according to the preset program or the feedback signal of the sensor. The output end of the stop driving member 101 drives the stop piece 102 to move upward in the vertical direction.

[0081] After the stop piece 102 rises to a certain height, it is located on the horizontal movement path of the fragile material in the channel. At this time, the fragile material continues to move with the conveying mechanism 4, and when it contacts the stop piece 102, its horizontal movement is blocked.

[0082] When it is necessary to let the fragile material continue to advance or proceed to the next step, the stop driving member 101 reverses its action to drive the stop piece 102 to move downward in the vertical direction, so that it leaves the horizontal movement path of the fragile material, and the fragile material can continue to move forward under the action of the conveying mechanism 4.

[0083] The position of the fragile material in the channel can be accurately controlled by the stop component 10. During the heating and other processing of the fragile material, accurate positioning of the position is crucial to ensure the processing quality. For example, the residence time and position accuracy of the fragile material in the heating area are ensured, thereby ensuring the uniformity and consistency of heating.

[0084] Referring to Figure 1 and Figure 2 In some embodiments, the brittle material heating device further comprises a heat insulation layer 11, which is arranged on the side of the upper jig 2 away from the lower jig 3 and on the side of the lower jig 3 away from the upper jig 2.

[0085] In this embodiment, the heat insulation layer 11 is arranged on the side of the upper and lower jigs 3 away from each other to prevent heat from being dissipated to the environment. Without the heat insulation layer 11, a large amount of heat will be wasted when the heating element 6 is working, reducing energy efficiency. With the heat insulation layer 11, the heat conduction coefficient is reduced, the heat is retained between the jig and the material, the energy utilization rate is improved, and the cost is reduced. When the jig is heated, without the heat insulation layer 11, other parts of the equipment will be damaged, such as reducing the performance of nearby wires and electronic components, and even scalding the operator. The heat insulation layer 11 can reduce the temperature of the jig surface and protect the equipment and personnel safety. The heat insulation layer 11 also maintains the temperature around the jig stable, avoiding temperature fluctuations due to heat dissipation. Unstable temperature will cause uneven heating of the brittle material, affecting the quality, and causing deformation, cracking, etc. The heat insulation layer 11 reduces heat dissipation, ensuring heating quality and consistency.

[0086] The above only describes some or preferred embodiments of the present application, neither the text nor the drawings can limit the scope of protection of the present application, any equivalent structural transformation using the content of the present application specification and drawings, or direct / indirect application in other related technical fields are included in the scope of protection of the present application.
