[0027] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as those commonly understood by technicians in the technical field of the present invention. The terms used in this specification are only for the purpose of describing specific embodiments and are not used to limit the present invention. The term "and / or" used in this specification includes any and all combinations of one or more related listed items.

[0028] In the production process of MLCC (Multilayer Ceramic Capacitor), pressing process is a key step. The capacitor structure blocks after pressing need to undergo high temperature treatment, which mainly involves taking out the capacitor structure blocks after pressing by an isostatic press, and then putting them into a heat treatment oven for high temperature treatment. The capacitor structure blocks are generally loaded in several material baskets for pressing by an isostatic press. After pressing is completed, the capacitor structure blocks are taken out together with the several material baskets.

[0029] The interior of the existing heat treatment oven is mainly a stainless steel cavity with a relatively simple structure. It is difficult to put the material basket containing the capacitor structure blocks into the heat treatment oven. Therefore, workers generally take the capacitor structure blocks out of the material basket first, and then place them into the heat treatment oven for high-temperature treatment. This makes the process of high-temperature treatment of the capacitor structure blocks more cumbersome.

[0030] The embodiment of the utility model arranges a slide rail in the heating box so that the material basket containing the capacitor structure blocks can slide directly into the heating chamber through the slide rail for high-temperature treatment, without first taking the capacitor structure blocks out of the material basket and then placing them inside the heat treatment oven for high-temperature treatment, thereby simplifying the process of high-temperature treatment of the capacitor structure blocks by the heat treatment device.

[0031] In order to facilitate readers to understand the inventive concept of the utility model, the specific structure of the heat treatment device is described below:

In this way, the feed basket 1 containing the capacitor structure block can be directly slid into the heating chamber 111 through the slide rail 14 for high temperature treatment, without first taking the capacitor structure block out of the feed basket 1 and then placing it inside the heat treatment oven for high temperature treatment, thereby simplifying the process of high temperature treatment of the capacitor structure block by the heat treatment device 1000.

[0033] In a preferred embodiment, an existing isostatic press is generally loaded with three material baskets 1, so the heating chamber 111 of the heating box 11 of the present application is designed to be able to load three material baskets 1 at a time, so that one heating box 11 can perform high-temperature treatment on the capacitor structural blocks of the three material baskets 1 of an isostatic press at one time; it can be understood that the accommodating space of the heating chamber 111 is not limited and can be adjusted according to the number of material baskets 1 loaded on the isostatic press.

[0034] As for the above-mentioned slide rail 14, the slide rail 14 can be set at the bottom of the heating chamber 111, and the shape of the slide rail 14 can be a straight line or a curve designed according to specific needs; the material of the slide rail 14 can be stainless steel or special alloys to meet the requirements of high temperature resistance, load bearing and sliding stability. Furthermore, the slide rail 14 can include a number of tracks (not shown) and fixings (not shown), and a certain distance is maintained between the several tracks. The material basket 1 can slide relative to the track, and the track can be a metal strip; one side of the fixing is fixed to the heating chamber 111, and the track is fixed to the other side of the fixing, and the fixing can be a screw or a clamp; the length and width of the slide rail 14 should be determined according to the size of the material basket 1 and the overall design of the heating box 11.

[0035] In some embodiments, the heating mechanism 100 also includes a fan 15, which is disposed at the top of the heating chamber 111. When the heat treatment device 1000 treats the capacitor structure block at high temperature, the fan 15 can circulate the hot air in the heating chamber 111 to improve the temperature uniformity in the heating chamber 111.

[0036] In a preferred embodiment, the number of the heating boxes 11, the box door 12, the heater 13, the slide rail 14 and the fan 15 are all four; the four heating boxes 11 are arranged in two rows and two columns along the first direction S1 and the second direction S2 to make the overall structure of the heat treatment device 1000 more compact, and the first direction S1 and the second direction S2 are perpendicular; one box door 12 is set in the opening 112 of one heating box 11; one heater 13 is set in the heating chamber 111 of one heating box 11; one slide rail 14 is set in the heating chamber 111 of one heating box 11, and one fan 15 is set in the heating chamber 111 of one heating box 11. It can be understood that the number of heating boxes 11, box doors 12, heaters 13, slide rails 14 and fans 15 is not limited and can be adjusted according to actual needs.

[0037] In some embodiments, please refer to Figure 3The heat treatment device 1000 also includes a lifting mechanism 200, and the heating mechanism 100 is arranged on the lifting mechanism 200. The lifting mechanism 200 can raise the heating mechanism 100 to a height matching the isostatic press, so as to facilitate the placement of the material basket 1 containing the capacitor structure block in the isostatic press into the heating mechanism 100.

[0038] Furthermore, the lifting mechanism 200 includes a frame 21, a support platform 22 and a driving assembly 23. The support platform 22 is slidably arranged on the frame 21, the heating mechanism 100 is arranged on the support platform 22, and the driving assembly 23 is fixed to the frame 21. The driving assembly 23 is used to drive the support platform 22 to slide relative to the frame 21. In this way, the heating mechanism 100 can be lifted and lowered in the vertical direction under the drive of the support platform 22 to reach a height matching the isostatic press. The frame 21 can be made of metal profiles, the support platform 22 can be a metal plate, and the driving assembly 23 can include a driving motor and a transmission chain. When the driving assembly 23 is started, the driving motor drives the transmission chain to rotate, and the transmission chain drives the support platform 22, thereby driving the support platform 22 to slide in the frame 21.

[0039] In a preferred embodiment, the frame 21 is arranged around the support platform 22, so that when the heating mechanism 100 follows the lifting and lowering of the support platform 22, the frame 21 can surround the heating mechanism 100, thereby reducing the possibility of the heating mechanism 100 sliding out of the support platform 22; further, the frame 21 is provided with a window 211, and the window 211 corresponds to the opening 112. The basket 1 equipped with the capacitor structure block can pass through the lifting mechanism 200 through the window 211 and enter the heating chamber 111 of the heating box 11.

[0040] In some embodiments, the heat treatment device 1000 further includes a human-machine interaction mechanism 300, and the human-machine interaction mechanism 300 includes a controller (not shown), a temperature sensor 31 and a display component 32; the controller is electrically connected to the temperature sensor 31 and the display component 32 respectively, the temperature sensor 31 is arranged in the heating chamber 111, the temperature sensor 31 is used to identify the temperature of the heating chamber 111, and the display component 32 is used to display the temperature identified by the temperature sensor 31. Preferably, the display component 32 is arranged in the lifting mechanism 200, which can facilitate the user to view on the one hand, and on the other hand, can reduce the possibility of the display component 32 being damaged by the high temperature of the heating mechanism 100. It can be understood that the display component 32 can also be arranged in the heating mechanism 100. Correspondingly, the controller can be arranged in the lifting mechanism 200 or the heating mechanism 100. Specifically, the display component 32 may include a display screen and a display driving circuit, the display driving circuit is electrically connected to the display screen and the controller respectively, the display screen may be a liquid crystal display (LCD) or an organic light emitting diode display (OLED), etc., for intuitively displaying temperature data; the display driving circuit is used to convert digital signals into signals that can be recognized by the screen to control the display content.

[0041] In some embodiments, the human-computer interaction mechanism 300 also includes a storage device (not shown), which is electrically connected to the controller. The storage device is used to store temperature data recognized by the temperature sensor 31. In this way, the user can retrieve temperature data for a long time through the human-computer interaction mechanism 300. The display component 32 can display the temperature data recognized by the temperature sensor 31 in real time, and can also display the temperature data recognized by the temperature sensor 31 in the past time period. For example, the controller adopts a programmable controller (such as Siemens S7-200 series or Mitsubishi FX series), so that the display component 32 can display the temperature curve, and the user can retrieve the temperature curve record for a long time.

[0042] In some embodiments, the human-computer interaction mechanism 300 further includes an operating component 33, and the controller is electrically connected to the operating component 33 and the heater 13, respectively. The operating component 33 is used for the user to adjust the temperature of the heating chamber 111. For example, the user inputs an electrical signal to the controller through the operating component 33, and the controller adjusts the heating power of the heater 13 through the electrical signal input by the operating component 33, thereby adjusting the temperature of the heating chamber 111. In addition, the user can retrieve the temperature curve record of the heating chamber 111 for a long time through the operating component 33. Preferably, the operating component 33 is arranged on the lifting mechanism 200, which can facilitate the user to view on the one hand, and reduce the possibility of the operating component 33 being damaged by the high temperature of the heating mechanism 100 on the other hand. It is understandable that the operating component 33 can also be arranged on the heating mechanism 100. Specifically, the operating component 33 may include buttons, knobs, touch screens, etc., and the user can input instructions through buttons, knobs and touch screens.

[0043] In some embodiments, the human-computer interaction mechanism 300 further includes a panel 34, and the display component 32 and the operating component 33 are arranged on the panel 34, so that the panel 34 can carry the display component 32 and the operating component 33 together, which is convenient for the installation of the display component 32 and the operating component 33; preferably, the panel 34 is arranged on the lifting mechanism 200 to meet the viewing and operation of the user, and can reduce the possibility of the display component 32 and the operating component 33 being damaged by the high temperature of the heating mechanism 100. It can be understood that the panel 34 can also be arranged on the heating mechanism 100. The material of the panel 34 can be a high temperature resistant material, such as an inorganic compound material and a high molecular polymer material.

[0044] In some embodiments, the heat treatment device 1000 further includes an electronic lock 400 and a controller, wherein the controller is electrically connected to the heater 13 and the electronic lock 400, respectively, and the electronic lock 400 is disposed on the heating box 11; wherein, when the box door 12 closes the opening 112 and the heater 13 is in a heating state, the electronic lock 400 locks the box door 12; when the heater 13 is not in a heating state, the electronic lock 400 does not lock the box door 12. For example, the controller adopts a programmable controller, and during the operation of the temperature program, the electronic lock 400 locks the box door 12, and the box door 12 cannot be opened manually. After the temperature program stops, the electronic lock 400 is automatically released, and the user can open the box door 12 to take out the basket 1. In this way, it is possible to reduce the possibility that the user accidentally opens the box door 12 during high-temperature operation of the heating box 11, thereby affecting the normal heat treatment process of the capacitor structure block, thereby improving the product yield.

[0045] In a preferred embodiment, the electronic lock 400 includes a lock seat (not shown) and a lock head (not shown), the lock seat is fixed to the heating box 11, and the lock head is arranged on the box door 12, wherein when the box door 12 closes the opening 112 and the heater 13 is in a heating state, the lock seat and the lock head are self-locking so that the box door 12 and the heating box 11 are locked; when the heater 13 is not in a heating state, the lock seat and the lock head are not self-locking so that the box door 12 and the heating box 11 are not locked.

[0046] In the embodiment of the utility model, the heat treatment device 1000 can place the basket 1 containing the capacitor structural block as a whole into the heating chamber 111 by setting the slide rail 14 in the heating chamber 111, which greatly improves the working efficiency. By setting the heating mechanism 100 on the lifting mechanism 200, so that the heating mechanism 100 matches the height of the isostatic press, the user can easily put the basket 1 containing the capacitor structural block into and out of the heating chamber 111 without the need for transportation, which greatly improves the working efficiency. By installing an electronic lock 400 on the heating box 11 to control the automatic locking of the box door 12 and the heating box 11, the locking and unlocking states of the electronic lock 400 are controlled according to the temperature program of the controller to avoid human error and improve the product yield. Through the human-computer interaction mechanism 300, the temperature curve of the heating chamber 111 can be automatically generated, which is convenient for tracing and improves the quality traceability.
