Abstract
Description
Technical Field
[0001] This utility model belongs to the field of thermally conductive adhesive technology, specifically relating to a thermally conductive adhesive production oven. Background Technology
[0002] Thermally conductive adhesive is an interface thermally conductive material widely used in electronic components, LED lighting, power modules, automotive electronics and other fields. It is mainly used to fill the microscopic gaps between the heat source and the heat sink, remove air, and establish an efficient heat conduction path. In the production process of thermally conductive adhesive, the purpose of "drying" or "curing" is to use heat to allow the solvent in the adhesive to fully evaporate and complete the cross-linking and curing reaction of the polymer resin, thereby forming a final product with stable structure and qualified performance.
[0003] In existing technologies, box-type or tunnel-type ovens are often used for batch drying of thermally conductive adhesives. However, in practical applications, thermally conductive adhesives vary significantly in their thermophysical properties and temperature sensitivity depending on their base material. Some materials may not cure completely due to insufficient heating, or they may age, yellow, or even develop internal bubbles due to excessive heating. At the same time, in order to improve efficiency, thermally conductive adhesives are often laid on trays for batch drying. However, the heating elements inside the oven are mostly fixed and the distance between them and the supporting tray cannot be adjusted. If the distance between a thin layer of adhesive and the heat source is too far, the drying time will be prolonged and the efficiency will be low. If the distance between a thick layer of adhesive and the heat source is too close, the surface layer will absorb too much heat and cure too quickly, forming a hard "shell", which will prolong the internal curing time. Utility Model Content
[0004] The purpose of this invention is to provide a thermally conductive adhesive production oven to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a thermally conductive adhesive production oven, comprising a box body, a door frame rotatably mounted on the front side of the box body, four fixing rods fixedly installed between the top and bottom of the inner wall of the box body, and multiple mounting plates connected between the four fixing rods, the mounting plates being divided into a top plate, a middle plate and a bottom plate, heating elements fixedly mounted on the bottom of the top plate and the middle plate, and placement components provided on the top of the middle plate and the bottom plate, the placement components comprising: L-shaped slide rails symmetrically arranged on the top of the middle plate and the bottom plate, a tray slidably placed between the L-shaped slide rails, and a handle provided on the front side of the tray.
[0006] Preferably, the placement assembly further includes: a placement groove is provided on the top of the middle plate and the bottom plate, and a limiting plate is symmetrically provided on the rear side of the inner wall of the placement groove.
[0007] Preferably, the upper part of the L-shaped slide rail is provided with a hook, and the lower inner side of the L-shaped slide rail is provided with a limiting post.
[0008] Preferably, a heat circulation groove is provided on the top of the housing, and a fan is provided inside the heat circulation groove.
[0009] Preferably, the number of middle plates is 2n+1.
[0010] Preferably, the number of middle plates is 3, and each of the left and right sides of the middle plates is provided with a first hinge rod that rotates in a cross manner, with the ends of the first hinge rods hinged to each other.
[0011] Preferably, both the top plate and the bottom plate are rotatably provided with two second hinge rods on their outer sides, and the ends of the second hinge rods are hinged to the ends of the first hinge rods.
[0012] Preferably, a driving component is provided at the bottom of the housing, and the output end of the driving component is connected to the base plate.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] This utility model, through the design of the driving component and the diamond-shaped hinge rod mechanism, drives the top plate, middle plate and bottom plate to move closer or further away synchronously and at equal distances, thereby achieving the distance between the heating component and the supporting tray. This allows the oven to quickly adapt to the optimal drying spacing according to the material characteristics and laying thickness of different thermally conductive adhesives, thus improving the applicability of the oven.
[0015] This utility model has a heat circulation fan installed on the top of the box to break the temperature stratification caused by the natural rise of hot air. It forces the heat to circulate and forms a stable and uniform thermal environment inside the box, ensuring that the thermally conductive adhesive on each tray can be heated evenly. This effectively avoids adhesive quality defects caused by local overheating or underheating, and ensures a high degree of consistency in product quality between batches.
[0016] The tray placement component in this invention can ensure that the tray can be accurately pushed into place, and can also prevent the tray from accidentally sliding out during the drying process due to equipment vibration or airflow disturbance, thus ensuring the continuity and stability of production.

Detailed Implementation
[0022] 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.
[0023] Example 1
[0024] like Figures 1 to 4 The oven shown is for producing thermally conductive adhesive. It includes a box body 1, a door frame 2 that is rotatably provided on the front side of the box body 1, four fixing rods 3 that are fixedly installed between the top and bottom of the inner wall of the box body 1, and multiple mounting plates 4 that are connected between the four fixing rods 3. The mounting plates 4 are divided into a top plate 41, a middle plate 42 and a bottom plate 43. Heating elements 5 are fixedly installed at the bottom of the top plate 41 and the middle plate 42. Placement components 6 are provided on the top of the middle plate 42 and the bottom plate 43. The placement components 6 include: L-shaped slide rails 601 that are symmetrically provided on the top of the middle plate 42 and the bottom plate 43, and a tray 602 that is slidably placed between the L-shaped slide rails 601. A handle 603 is provided on the front side of the tray 602. The placement component 6 also includes: a placement groove 604 on the top of the middle plate 42 and the bottom plate 43, and a limiting plate 605 symmetrically provided on the rear side of the inner wall of the placement groove 604; a hook 7 rotatably provided on the upper part of the L-shaped slide rail 601, and a limiting post 8 provided on the inner side of the lower part of the L-shaped slide rail 601; a heat circulation groove 9 is opened on the top of the box body 1, and a fan 10 is provided in the heat circulation groove 9; the number of middle plates 42 is 2n+1, and the number of middle plates 42 is 3, and the left and right sides of the middle plates 42 are provided with first hinge rods 11 that are rotatably arranged in a cross manner, and the ends of the first hinge rods 11 are hinged to each other; two second hinge rods 12 are rotatably provided on the outer sides of the top plate 41 and the bottom plate 43, and the ends of the second hinge rods 12 are hinged to the ends of the first hinge rods 11; a driving component 13 is provided at the bottom of the box body 1, and the output end of the driving component 13 is connected to the bottom plate 43.
[0025] This invention utilizes the design of the driving component 13 and the diamond-shaped hinge rod mechanism to drive the top plate 41, middle plate 42, and bottom plate 43 to move synchronously and equidistantly towards or away from each other, thereby adjusting the distance between the heating element 5 and the supporting tray 602. This allows the oven to quickly adapt to the optimal drying spacing based on the material characteristics and thickness of different thermally conductive adhesives, improving the oven's applicability. A heat circulation fan 10 is installed at the top of the oven body 1 to break the temperature stratification caused by the natural rise of hot air, forcing heat circulation and creating a stable and uniform thermal environment within the oven. This ensures that the thermally conductive adhesive on each tray 602 is heated evenly, effectively avoiding adhesive quality defects caused by localized excessively high or insufficient temperatures, and guaranteeing high consistency in product quality between batches. The tray 602 placement component 6 in this invention ensures that the tray 602 is accurately pushed into place and prevents the tray 602 from accidentally sliding out during the drying process due to equipment vibration or airflow disturbance, ensuring the continuity and stability of production.
[0026] Example 2
[0027] like Figures 1 to 4 The oven shown is for producing thermally conductive adhesive. It includes a chamber body 1 with a rotating door frame 2 on the front side. The door frame 2 is used to open the chamber body 1 to allow the insertion of a tray 602 containing thermally conductive adhesive and to remove it after drying. Closing the door frame facilitates the drying of the thermally conductive adhesive. Four fixing rods 3 are fixedly installed between the top and bottom of the inner wall of the chamber body 1. Multiple mounting plates 4 are connected between the fixing rods 3. The number of mounting plates 4 depends on the actual height of the chamber body 1, specifically consisting of one top plate 41, multiple middle plates 42, and one bottom plate 43. The top plate 41 is slidably connected to the fixing rod 3, and the bottom plate 43 is slidably connected to the fixing rod 3. The number of middle plates 42 is 2n+1. When the number of mounting plates 4 is limited to 5 in this embodiment, the number of middle plates 42 is 3. The upper and lower middle plates 42 are slidably connected to the fixing rod 3, and the middle middle plate 42 is fixedly connected to the fixing rod 3. It can be understood that when the number of mounting plates 4 is 7, the middle middle plate 42 is still fixedly connected to the fixing rod 3, and the other middle plates 42 are slidably connected to the fixing rod 3.
[0028] Furthermore, a drive unit 13 is provided at the bottom of the housing 1. The drive unit 13 can be an electronic device such as a motor or a telescopic cylinder. The output end of the drive unit 13 is connected to the bottom plate 43. The middle plate 42 is provided with first hinge rods 11 on both sides, and the ends of the first hinge rods 11 are hinged to each other. At the same time, two second hinge rods 12 are provided on the outer sides of the top plate 41 and the bottom plate 43. The ends of the second hinge rods 12 are hinged to the ends of the first hinge rods 11. The second hinge rods 12 are equal to half of the first hinge rods 11. Finally, the mounting plates 4 are connected by a rhomboid frame. When the middle plate 42 is fixed, when the drive unit 13 moves the bottom plate 43 upward, all the mounting plates 4 will move closer to the middle plate 42 at the same distance under the action of the first hinge rods 11 and the second hinge rods 12. Conversely, when the drive unit 13 moves the bottom plate 43 downward, the mounting plates 4 will move away from the middle plate 42.
[0029] Furthermore, when heating elements 5 are fixedly installed at the bottom of both the top plate 41 and the middle plate 42, the tray 602 containing thermally conductive adhesive can be placed on top of the middle plate 42 and the bottom plate 43. This will cause the drive element 13 to operate in advance, thereby adjusting the spacing of each mounting plate 4 (including the top plate 41, the middle plate 42, and the bottom plate 43) to achieve the adjustment of the drying spacing. In this way, thermally conductive adhesive of different thicknesses or materials can be flexibly adapted according to different drying requirements, effectively improving the heat utilization efficiency and drying uniformity.
[0030] Meanwhile, a heat circulation tank 9 is opened at the top of the chamber 1, and a fan 10 is installed in the heat circulation tank 9. This can effectively prevent the temperature stratification caused by the natural rise of hot air, and quickly and evenly blow the heat generated by the bottom heating unit to every corner of the chamber. This ensures that each layer of thermally conductive adhesive is in a stable and uniform thermal environment, avoiding the problem of the paste charring due to excessive local temperature or incomplete drying due to insufficient temperature, thus ensuring the consistency of drying quality. Moreover, the solvent or carrier contained in the thermally conductive adhesive will evaporate after being heated. The directional airflow formed by the fan 10 can form a continuously flowing "air curtain" on the surface of the thermally conductive adhesive. This greatly accelerates the dissipation speed of volatile components on the surface of the paste and quickly removes the humid air rich in solvent vapor from the surface of the workpiece, greatly improving the overall drying efficiency and drying effect.
[0031] Example 3
[0032] like Figures 1 to 4The oven for producing thermally conductive adhesive shown includes a body 1, with a placement assembly 6 on the top of a middle plate 42 and a bottom plate 43. The placement assembly 6 includes: L-shaped slide rails 601 symmetrically arranged on the top of the middle plate 42 and the bottom plate 43, through which a tray 602 can be smoothly slidably placed between the L-shaped slide rails 601 via its two side edges; a handle 603 is provided on the front side of the tray 602 for workers to push and pull the tray 602; to ensure that the tray 602 can reach the preset work position after being pushed in, a placement groove 604 is provided on the top of the middle plate 42 and the bottom plate 43, and the L-shaped slide rails 601 are installed on the left and right sides of the placement groove 604; a limiting plate 605 is symmetrically arranged on the rear side of the inner wall of the placement groove 604. When the tray 602 is pushed to the end along the slide rail, its rear end will come into close contact with the limiting plate 605, thereby limiting the rear of the tray 602 and preventing it from going too deep.
[0033] A hook 7 is rotatably provided on the upper part of the L-shaped slide rail 601 (i.e., the upper part of the vertical bar), and a limiting post 8 is provided on the lower inner side of the L-shaped slide rail 601 (i.e., the side of the horizontal bar near the mounting groove 604). The hook 7 is rotated outward in advance so that it does not hook with the limiting post 8, so that the tray 602 can be pushed into place. After being pushed in, the hook 7 is rotated inward until it hooks the lower limiting post 8. At this time, the hook 7 is tilted and forms a stable triangular shape with the cross-section of the L-shaped slide rail 601, thereby limiting the front of the tray 602 and preventing the risk of the tray 602 accidentally sliding out due to vibration or airflow disturbance during the operation of the oven.
[0034] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
