Description

Technical Field

[0001] This invention relates to the field of aluminum substrate processing technology, and specifically to a hot pressing device for producing aluminum substrates with intelligent high-precision temperature measurement. Background Technology

[0002] Aluminum substrate is a type of copper-clad laminate with a metal base that offers excellent heat dissipation. A typical single-sided board consists of three layers: a circuit layer (copper foil), an insulating layer, and a metal base layer. It is commonly found in LED lighting products. It has two sides: a white side for soldering LED leads and a white side for the aluminum substrate, which is usually coated with thermally conductive paste before contacting the heat-conducting parts. However, traditional aluminum substrate hot-pressing equipment has a simple structure and poor performance.

[0003] The prior art patent "CN 213322175 U, A Hot Press Box for Aluminum Substrate Production" describes a hot press box for aluminum substrate production, comprising a box body with a filter chamber and an installation chamber inside. An installation frame is fixed to the inner side of the installation chamber, and a cylinder is mounted on the surface of the installation frame. A connecting block is fixedly connected to the lower end of the cylinder, and a pressure plate is mounted on the lower end of the connecting block. A heating block and a temperature sensor are mounted on the surface of the pressure plate. This hot press box directly heats the pressure plate through the heating block and is controlled by an electrical connection between the temperature sensor and a temperature controller. Compared to the traditional method of preheating heat transfer oil with a heating device and then allowing the heat transfer oil to flow into the pressure plate to heat it, this method has a simpler structure and significantly improved heating efficiency. Furthermore, the hot press box uses an electric telescopic rod to push the bottom plate open the sealed door, allowing the aluminum substrate to be replaced outside the box. Compared to the existing method of opening the box door and reaching inside to replace the aluminum substrate, this method reduces the risk of high-temperature hand exposure and heat loss due to the large opening and closing of the box door.

[0004] However, the existing hot press boxes for aluminum substrate production still have the following drawbacks: First, although the existing hot press boxes for aluminum substrate production have solved the problem of manually inserting a hand into the box to replace the aluminum substrate to some extent, their structural design is unreasonable. When the hand is extended outside the box to replace the aluminum substrate, the hot press box is in an unsealed state, and replacing the aluminum substrate requires sufficient time. This time-consuming and laborious process causes heat loss inside the hot press box, which in turn affects the temperature of the pressing plate, reduces the subsequent pressing quality, and is detrimental to the continuous pressing of aluminum substrates. Second, the existing hot press boxes for aluminum substrate production are not effective, specifically, the temperature control of the pressing plate is not precise enough. Further analysis shows that the temperature sensor of the pressing plate in the existing technology is controlled by a temperature controller, which is only a theoretical explanation and not intelligent enough. In the hot pressing production process of aluminum substrates, different specifications of aluminum substrate series products may require different and more precise temperature requirements. The temperature controller mentioned in the existing technology cannot achieve diversified temperature sampling, screening, and algorithm identification of the limit temperature of the pressing plate, and therefore cannot make intelligent and reasonable temperature control feedback commands to the pressing plate. Third, the design of the pressure plate drive structure in the existing hot press box for aluminum substrate production is unreasonable. Specifically, the existing technology only uses a single cylinder for operation, without specifying or detailing the requirements for the cylinder's driving speed and pressure. However, different thicknesses of aluminum substrates require different pressing speeds and forces during the hot pressing process. Furthermore, the pressing of aluminum substrates during production requires layered, progressively applied pressure to improve the production quality of the hot press. Therefore, we need an intelligent, high-precision temperature-measuring hot press for aluminum substrate production. Summary of the Invention

[0005] To address the shortcomings and deficiencies of existing aluminum substrate production and processing technologies, this invention provides an intelligent, high-precision temperature measurement hot pressing device for aluminum substrate production. This device features a reasonable structural design, improves the efficiency of hot pressing and aluminum substrate replacement while ensuring sealing, saves time and labor, enables different levels of pressing speed and force, meets progressive loading requirements, and allows for diverse temperature sampling, screening, and algorithmic identification of the platen's limit temperature, while also providing intelligent and reasonable temperature control for the platen.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a hot pressing device for producing aluminum substrates with intelligent high-precision temperature measurement, the hot pressing device comprising a support mechanism, a pressing mechanism, and a temperature control unit; the support mechanism comprising a base plate, a housing, support plates, and a driving component; the base plate is distributed left and right, and side wing plates are also provided on the left and right sides; the housing is vertically mounted at the center of the base plate and has an internal cavity; there are two support plates distributed left and right, and the upper surface is provided with a groove adapted to the aluminum substrate; the driving component is configured such that when one of the support plates drives the aluminum substrate... When the pressing operation is performed in the preset position of the cavity, another support plate is located outside the box for standby, maintaining the sealing effect of the cavity; the pressing mechanism includes a first hydraulic cylinder, a second hydraulic cylinder, and a pressing plate; the first hydraulic cylinder consists of four cylinders distributed at the four corners, with one end fixedly connected to the top of the box and the other end fixedly connected to the pressing plate. The first hydraulic cylinders maintain the following parameters: moving speed V and pressing force F to drive the pressing plate to move; the second hydraulic cylinders are vertically distributed, with the top end located at the center of the box and the bottom end connected to a transition plate. The connecting plate is fixedly connected to the pressing plate, so that when the first hydraulic cylinder starts the pressing operation, the second hydraulic cylinder does not work, forming a first-stage pressing; after the first hydraulic cylinder finishes its operation, the second hydraulic cylinder starts and continues to move downwards to perform the pressing operation with the following parameters: moving speed (0.6-0.8)V and pressing force (1.2-1.5)F, forming a second-stage pressing; the temperature control unit includes a resistance wire, a temperature detection sensor, a cooling fan, and a controller; the resistance wire is spirally distributed inside the pressing plate; the temperature detection sensor is located on the pressing plate. On one side of the laminated board, the box body has an air inlet on one side and an air outlet on the other side. The cooling fan is fixedly installed at the air outlet by a bracket. The controller is connected to the resistance wire, the temperature sensor and the cooling fan, and is configured to transmit a signal to the resistance wire to continuously heat it to a preset temperature T when the temperature sensor detects a low temperature extreme value; when the temperature sensor detects a high temperature extreme value, it transmits a signal to the resistance wire to shut down the operation, and at the same time triggers the cooling fan to start the cooling fan to ventilate and cool the laminated board to the preset temperature T.

[0007] As a preferred technical solution: the driving component includes a drive motor, a drive rod, and a guide rod; the drive motor is fixedly mounted on the base plate via a bracket; the drive rod extends laterally and is rotatably disposed between the two side wing plates, maintaining connection with the output shaft of the drive motor; the guide rod is distributed laterally and disposed between the two side wing plates; both support plates are sleeved and installed between the drive rod and the guide rod, maintaining a threaded connection between the support plates and the drive rod, and a sliding connection between the support plates and the guide rod; the distance between the two support plates is equal to the length of the housing.

[0008] A further preferred technical solution: the driving component further includes a sealing plate; there are three sealing plates evenly distributed, and the sealing plates are threadedly connected to the driving rod, and slidably connected to the guide rod; and the distance between two adjacent sealing plates is also equal to the length of the housing.

[0009] A further preferred technical solution: a sealing rubber ring is also provided at the outer edge of the sealing plate.

[0010] As a preferred technical solution: the pressing plate is connected to the first hydraulic cylinder through a connecting plate, one side of the connecting plate is welded to the output shaft of the first hydraulic cylinder, and the other side is connected to the pressing plate through fastening bolts.

[0011] A further preferred technical solution: the pressing plate is made of alloy plate and includes an upper plate and a lower plate, and the lower plate has a groove for mounting the resistance wire; the upper plate and the lower plate are connected by fixing bolts.

[0012] A further preferred technical solution: an insulation layer is provided between the upper plate and the lower plate.

[0013] A further preferred technical solution: The controller includes a signal receiving unit, an algorithm processing unit, and a data storage unit; the signal receiving unit is used to receive the real-time temperature of the pressing plate from the temperature sensor in a manner that accumulates and records the sampled samples sequentially, and to form a subset within a unit time for a single aluminum substrate pressing operation, and finally form a temperature database; the algorithm processing unit is used to perform numerical comparison of N sampled temperature data in the subset using algorithm formulas, and then identify and filter out the low temperature extreme value and the high temperature extreme value;

[0014] The algorithm formula for the algorithm processing unit is as follows:

[0015] Tmin-i=min(T1, T2, T3...Ti);

[0016] Tmax-j= max(T1, T2, T3…Tj);

[0017] Where Tmin-i is the sampling temperature when the i-th temperature sensor reaches the low temperature extreme value; at this time, the algorithm processing unit feeds back a heating command to the resistance wire; Tmax-j is the sampling temperature when the j-th temperature sensor reaches the high temperature extreme value; at this time, the algorithm processing unit feeds back a cooling command to the resistance wire and the cooling fan.

[0018] The data storage unit is used to record and store the temperature data of the signal receiving unit, and stores the data in the form of an Excel spreadsheet, with each single pressing of the aluminum substrate as a unit. At the same time, the temperature data information of the pressing of the aluminum substrate per unit quantity is defined as a tag and displayed on the page in the form of a tab page. Clicking on different tags displays and displays the hot pressing temperature status of the aluminum substrate for different quantities.

[0019] A further preferred technical solution: the preset optimal temperature range for hot pressing of the aluminum substrate is T1, wherein the preset alarm low temperature limit of the temperature sensor is 0.85T; and the preset alarm high temperature limit of the temperature sensor is 1.3T.

[0020] A further preferred technical solution: an air intake grille is provided at the air inlet, and the air intake grille is connected to the cooling fan by a signal; a filter bag is also provided at the air outlet, and the filter bag is mainly composed of HEPA air filter cotton and activated carbon wrapped inside the HEPA air filter cotton; a through hole is provided at the lower end of the side wall of the box.

[0021] The advantages of this invention compared to existing technologies are as follows: The hot pressing equipment has a reasonable structural design. Through the rational arrangement of two support plates and three sealing plates, it ensures that while one support plate drives the aluminum substrate to the preset position in the cavity for pressing, the other support plate is positioned outside the chamber for standby. This also maintains the sealing effect of the cavity, allowing workers sufficient time to replace the aluminum substrate. This avoids the problem of temperature loss inside the hot pressing chamber, which affects the temperature of the pressing plate and reduces the subsequent pressing quality, as is the case with existing technologies. Thus, while ensuring sufficient sealing of the chamber, the efficiency of hot pressing and replacement of aluminum substrates is greatly improved, saving time and labor.

[0022] This hot-pressing equipment performs well. By coordinating the first and second hydraulic cylinders and the pressing plate, and adjusting the overflow and pressure valves of the respective cylinders during initialization, the speed and pressure of the hydraulic cylinders are regulated. When the first hydraulic cylinder begins pressing, the second hydraulic cylinder remains inactive, forming a first-stage pressing. After the first hydraulic cylinder completes its work, the second hydraulic cylinder begins and continues pressing at a moving speed of (0.6-0.8)V and a pressing force of (1.2-1.5)F, forming a second-stage pressing. This further fulfills the need for different pressing speeds and pressure levels, and progressive loading, for aluminum substrates of different specifications and thicknesses, making it more practical.

[0023] This hot-pressing equipment, through the coordinated use of resistance wires, temperature sensors, cooling fans, and controllers, optimizes a temperature sampling and filtering algorithm. When the temperature sensor detects a low-temperature extreme, it sends a signal to the resistance wire to continuously heat the platen to a preset temperature T. When the temperature sensor detects a high-temperature extreme, it sends a signal to the resistance wire to shut down the operation, and simultaneously triggers the cooling fan to ventilate and cool the pressing platen to the preset temperature T. The preset temperature T is the optimal hot-pressing temperature for the aluminum substrate. This achieves diversified temperature sampling and filtering, and algorithmic identification of the platen's extreme temperature values, further enabling intelligent and reasonable temperature control of the platen. This makes the temperature measurement and control of the pressing platen more precise and efficient, further improving the hot-pressing quality and efficiency of the aluminum substrate.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] It should be noted that, in specific embodiments of the present invention, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any actual relationship or order between these entities or operations. Furthermore, terms such as "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, the use of phrases such as "comprising a..." to define an element does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0036] In the description of this invention, unless otherwise explicitly specified and limited, the terms "installed," "connected," "linked," and "equipped" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; or they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0037] Example: Figures 1 to 8 The image shows an intelligent, high-precision temperature-measuring hot pressing device for aluminum substrate production. The hot pressing device includes a support mechanism 1, a pressing mechanism 2, and a temperature control unit 3. The support mechanism 1 includes a base plate 11, a housing 12, support plates 13, and a driving component 14. The base plate 11 is distributed horizontally, with side wing plates 15 on both sides; the side wing plates are welded to the base plate. Support legs can be provided at the lower end of the base plate for auxiliary support and stability. The housing 12 is vertically mounted at the center of the base plate 11 and has an internal cavity 16. Two support plates 13 are symmetrically distributed horizontally, and their upper surfaces have grooves 17 adapted to fit the aluminum substrate. The driving component 14 is configured such that when one support plate 13 moves the aluminum substrate to a preset position in the cavity 16 for pressing, the other support plate 13 is positioned outside the housing 12 for standby, maintaining the sealing effect of the cavity 16. The lower end of the side wall of the housing 12 is also provided with a through hole 121, which is adapted to the sealing plate structure and is mainly used to provide conditions for the movement of the support plate.

[0038] Reference Figure 2As shown: Specifically, the driving component 14 includes a drive motor 141, a drive rod 142, and a guide rod 143. The drive motor 141 is fixedly mounted on the base plate 11 via a bracket and is connected to a control switch. The drive rod 142 extends laterally and is rotatably disposed between the two side wing plates 15, maintaining connection with the output shaft of the drive motor 141; the drive rod is located at the center of the side wing plate, and the two are connected by a keyway to maintain relative rotation but not relative movement. The guide rod 143 is distributed laterally and disposed between the two side wing plates 15; there are two guide rods, symmetrically distributed about the front and rear of the drive rod; the guide rods are connected to the side wing plates via bearings. Two support plates 13 are sleeved and installed between the drive rod 142 and the guide rod 143, maintaining a threaded connection between the support plate 13 and the drive rod 142, and a sliding connection between the support plate 13 and the guide rod 143. The support plate maintains sliding contact with the base plate, facilitating good support during the pressing process. With this setup, the drive motor is a servo-controlled motor, which precisely controls the movement stroke. Then, through forward and reverse drive, it drives the drive rod to rotate synchronously, thereby moving the support plate on the drive rod left and right, realizing the cyclic operation of loading, hot pressing and unloading of aluminum substrate.

[0039] This hot-pressing equipment features a rational structural design. Through the coordinated arrangement of two support plates and three sealing plates, it ensures that while one support plate moves the aluminum substrate to the preset position within the cavity for pressing, another support plate remains on the outside of the chamber for standby. This maintains the cavity's sealing effect, allowing sufficient time for workers to replace the aluminum substrate. This avoids the problem of temperature loss within the hot-pressing chamber, which affects the temperature of the pressing plates and reduces subsequent pressing quality, a problem inherent in existing technologies. Therefore, while ensuring sufficient chamber sealing, it significantly improves the efficiency of hot-pressing and replacement of the aluminum substrate, saving time and labor.

[0040] like Figure 3As shown: the distance between the two support plates 13 is equal to the length of the housing 12. This arrangement ensures that the drive motor's rotation is based on the requirement that the support plate moves the entire length of the housing, thus guaranteeing precise control during the reciprocating operation of one support plate in the hot pressing process and the other in the unloading and new loading processes. In this embodiment, the drive component 14 also includes three sealing plates 144. The sealing plates 144 are evenly distributed, with a threaded connection between the sealing plates 144 and the drive rod 142, and a sliding connection between the sealing plates 144 and the guide rod 143; the distance between two adjacent sealing plates 144 is also equal to the length of the housing 12. Simply put, the positional relationship between the sealing plates and the support plates is that two adjacent sealing plates are symmetrical about the support plates. A sealing rubber ring 145 is also provided at the outer edge of the sealing plate 144, and the sealing plate 144 is fitted with the through hole 121. This arrangement facilitates the formation of a sealed environment for the housing.

[0041] Let's analyze the initial state, where one support plate is inside the box (the current support plate) and another support plate is on the right side of the box, as an example: Figure 3 As shown: After the aluminum substrate of the current support plate undergoes hot pressing, the drive motor starts, causing the drive rod to rotate synchronously. This, in turn, causes both support plates to move synchronously to the left by the length of the box, i.e., length L. At this time, the support plate on the right side moves to directly below the pressing plate, awaiting the hot pressing process. The current support plate moves the hot-pressed aluminum substrate to the left side of the box body, where unloading begins, and the placement of new aluminum substrate material is completed. See details... Figure 4 As shown. After the aluminum substrate on the right support plate is hot-pressed, the drive motor reverses, causing both support plates to move synchronously to the right. The right support plate then moves the hot-pressed aluminum substrate to the right side of the box (i.e., the reset state), starting the unloading process and placing the new aluminum substrate material. At this point, the current support plate is directly below the pressing plate, and this cycle repeats. Throughout the entire movement, a sealing plate always blocks the through hole of the box, meaning there are always two sealing plates working with the box to form a sealed environment, preventing heat loss and ensuring the uniformity of the cavity temperature inside the box.

[0042] like Figure 5As shown: In this embodiment, the pressing mechanism 2 includes a first hydraulic cylinder 21, a second hydraulic cylinder 22, and a pressing plate 23. Four first hydraulic cylinders 21 are distributed at the four corners, with one end fixedly connected to the top of the housing 12 and the other end fixedly connected to the pressing plate 23. Specifically, the pressing plate 23 is connected to the first hydraulic cylinder 21 via a connecting plate 25. One side of the connecting plate 25 is welded to the output shaft of the first hydraulic cylinder 21, and the other side is connected to the pressing plate 23 via fastening bolts. The first hydraulic cylinder 21 maintains preset parameters of a moving speed V and a pressing force F to move the pressing plate 23; this can be adjusted and controlled via the cylinder's overflow valve and pressure valve. The second hydraulic cylinders 22 are vertically distributed, with their top ends located at the center of the housing 12 and their bottom ends connected to a transition plate 24. The transition plate 24 is fixedly connected to the pressing plate 23, ensuring that when the first hydraulic cylinder 21 initiates the pressing operation, the second hydraulic cylinder 22 does not operate, forming a single-stage pressing. After the first hydraulic cylinder 21 completes its operation, the second hydraulic cylinder 22 opens and continues to move downwards at preset parameters of a moving speed (0.6-0.8)V and a pressing force (1.2-1.5)F to perform the pressing operation, forming a secondary pressing. For example, Figure 7 As shown: The pressing plate 23 is made of aluminum-nickel alloy, which not only has good thermal conductivity but also sufficient strength and corrosion resistance. The pressing plate includes an upper plate 231 and a lower plate 232, and the lower plate 232 has a slot 233 for mounting the resistance wire 31; the upper plate 231 and the lower plate 232 are connected by fixing bolts 234. A heat insulation layer 235 is also provided between the upper plate 231 and the lower plate 232. With this configuration, the power required for the electrical components of the hot pressing equipment is obtained by connecting to an external power source.

[0043] This hot-pressing equipment performs well. By coordinating the first and second hydraulic cylinders and the pressing plate, and adjusting the overflow and pressure valves of the respective cylinders during initialization, the speed and pressure of the hydraulic cylinders are regulated. When pressing an aluminum substrate, the first hydraulic cylinder is activated first. As its output shaft moves the pressing plate downwards to compress the aluminum substrate, the second hydraulic cylinder remains inactive, its output shaft moving with the pressing plate, thus forming the first stage of pressing. After the first hydraulic cylinder completes its work, the second hydraulic cylinder is activated, maintaining a downward movement speed of (0.6-0.8)V and a pressing force of (1.2-1.5)F to continue pressing, forming the second stage of pressing. This process is slower but more pressure-intensive, facilitating better application of pressing force to the aluminum substrate. This hot-pressing equipment further fulfills the need for different pressing speeds and pressure levels, and progressive loading, for aluminum substrates of different specifications and thicknesses; thus, it is more practical.

[0044] like Figure 7As shown: In this embodiment, the temperature control unit 3 includes a resistance wire 31, a temperature sensor 32, a cooling fan 33, and a controller 34. The resistance wire 31 is spirally distributed within the pressing plate 23; this arrangement results in more uniform temperature distribution and facilitates more precise temperature control. The temperature sensor 32 is located on one side of the pressing plate 23. In a preferred embodiment, four temperature sensors distributed at the four corners can be used, further enhancing the uniformity and consistency of temperature sampling. See details... Figure 6 As shown: The housing 12 has an air inlet 18 on one side and an air outlet 19 on the other side. The cooling fan 33 is fixedly installed at the air outlet 19 via a bracket. This arrangement provides a strong foundation for subsequent temperature control. The controller 34 maintains signal connections with the resistance wire 31, the temperature sensor 32, and the cooling fan 33, and is configured to transmit a signal to the resistance wire 31 to continuously heat it to a preset temperature T when the temperature sensor 32 detects a low-temperature extreme value. When the temperature sensor 32 detects a high-temperature extreme value, it transmits a signal to the resistance wire 31 to shut down the operation, and simultaneously triggers the cooling fan 33 to start ventilating and cooling the pressing plate 23 to the preset temperature T. The start of the cooling fan triggers the activation of the air intake grille, allowing external airflow to enter and cool the pressing plate. The preset optimal temperature range for hot pressing of the aluminum substrate is T1, where the preset alarm low-temperature extreme value of the temperature sensor is 0.85T; the preset alarm high-temperature extreme value of the temperature sensor is 1.3T. Taking the lamination requirements of the XD-L1 type aluminum substrate as an example, the optimal hot-pressing temperature T of this aluminum substrate is 260 degrees Celsius; the preset optimal temperature range T1 for hot pressing of the aluminum substrate is 250-270 degrees Celsius. Among them, the extreme low temperature is 221 degrees Celsius and the extreme high temperature is 338 degrees Celsius.

[0045] like Figure 8 As shown: In this embodiment, the controller 34 includes a signal receiving unit 341, an algorithm processing unit 342, and a data storage unit 343. The signal receiving unit 341 is used to receive the real-time detected temperature of the pressing plate 23 by the temperature sensor in a manner that accumulates and records the sampled data sequentially, and forms a subset within a unit time for each single aluminum substrate pressing operation, and finally forms a temperature database. The algorithm processing unit 342 is used to perform numerical comparison of N sampled temperature data in the subset using an algorithm formula, and then identify and filter out the low temperature extreme value and the high temperature extreme value; the data storage unit 343 is used to record and store the temperature data of the signal receiving unit 341, and stores the data in the form of an Excel spreadsheet, with each single pressing of the aluminum substrate as a quantity; at the same time, the temperature data information of the pressing of the aluminum substrate per unit quantity is defined as a tag and displayed on the page in the form of a tab page, and clicking on different tags displays and views the hot pressing temperature status of the aluminum substrate under different quantities.

[0046] The algorithm formula for the algorithm processing unit 342 is as follows:

[0047] Tmin-i=min(T1, T2, T3...Ti);

[0048] Tmax-j= max(T1, T2, T3…Tj);

[0049] Where Tmin-i is the sampling temperature when the i-th temperature sensor reaches the low-temperature extreme value. At this time, the algorithm processing unit 342 sends a heating command to the resistance wire 31. Tmax-j is the sampling temperature when the j-th temperature sensor reaches the high-temperature extreme value; at this time, the algorithm processing unit 342 sends a cooling command to the resistance wire 31 and the cooling fan 33.

[0050] The algorithm code for the algorithm processing unit 342 is as follows:

[0051] plaintext

[0052] function findMaxMin(data);

[0053] if len(data) == 0;

[0054] return None, None # If the data is empty, return None

[0055] max_value = data[0]

[0056] min_value = data[0]

[0057] for i in range(1,len(data));

[0058] if data[i] > max_value;

[0059] max_value = data[i]

[0060] if data[i] <min_value;

[0061] min_value = data[i]

[0062] return max_value, min_value;

[0063] …

[0064] Example:

[0065] Suppose the dataset is 'data=【230,228,240,228250,338,229,260,250,230,250】':

[0066] initialization:

[0067] 'max_value=230'

[0068] 'min_value=230'

[0069] Traverse the dataset:

[0070] 'i=1':'data[1]'=228,'228<230',so'min_value=228'.

[0071] 'i=2':'data[2]'=240,'240>230', so''max_value=240'.

[0072] 'i=3':'data[3]'=228,'228<228', (unchanged).

Claims

1. A hot pressing device for producing aluminum substrates with intelligent high-precision temperature measurement, characterized in that: The hot pressing equipment includes a support mechanism, a pressing mechanism, and a temperature control unit. The support mechanism includes a base plate, a housing, support plates, and a driving component. The base plate is distributed horizontally, with side wing plates on both sides. The housing is vertically mounted at the center of the base plate and has an internal cavity. There are two support plates distributed horizontally, with grooves on their upper surfaces to accommodate aluminum substrates. The driving component includes a drive motor, a drive rod, and a guide rod. The drive motor is fixedly mounted to the base plate via a bracket. The drive rod extends horizontally and is rotatably positioned between the two side wing plates, maintaining a connection to the output shaft of the drive motor. The guide rod is distributed horizontally and positioned between the two side wing plates. Both support plates are fitted between the drive rod and the guide rod, maintaining a threaded connection between the support plate and the drive rod, and a sliding connection between the support plate and the guide rod. The distance between the two support plates is equal to the length of the housing. The driving component also includes three sealing plates; the sealing plates are evenly distributed and are threadedly connected to the driving rod, and are slidably connected to the guide rod; and the distance between two adjacent sealing plates is equal to the length of the housing. The pressing mechanism includes a first hydraulic cylinder, a second hydraulic cylinder, and a pressing plate. Four first hydraulic cylinders are distributed at the four corners, with one end fixedly connected to the top of the housing and the other end fixedly connected to the pressing plate. The first hydraulic cylinders maintain preset parameters of a moving speed V and a pressing force F to move the pressing plate. The second hydraulic cylinders are vertically distributed, with their tops positioned at the center of the housing and their bottoms connected to a connecting plate. The connecting plate is fixedly connected to the pressing plate, ensuring that when the first hydraulic cylinders are engaged in pressing operations, the second hydraulic cylinders are not working, forming a single-stage pressing. After the first hydraulic cylinders have finished their work, the second hydraulic cylinders are engaged and maintain preset parameters of a moving speed of 0.6V-0.8V and a pressing force of 1.2F-1.5F to continue pressing downwards. The process involves a two-stage pressing operation. The temperature control unit includes a resistance wire, a temperature sensor, a cooling fan, and a controller. The resistance wire is spirally arranged within the pressing plate. The temperature sensor is located on one side of the pressing plate. The housing has an air inlet on one side and an air outlet on the other. The cooling fan is fixedly mounted to the air outlet via a bracket. The controller maintains signal connections with the resistance wire, the temperature sensor, and the cooling fan, and is configured to transmit a signal to the resistance wire to continuously heat it to a preset temperature T when the temperature sensor detects a low-temperature extreme value. When the temperature sensor detects a high-temperature extreme value, it transmits a signal to the resistance wire to shut down the operation and simultaneously triggers the cooling fan to ventilate and cool the pressing plate to the preset temperature T.

6. The intelligent high-precision temperature measurement hot pressing equipment for aluminum substrate production as described in claim 5, characterized in that: The controller includes a signal receiving unit, an algorithm processing unit, and a data storage unit. The signal receiving unit receives the real-time temperature of the pressing plate from the temperature sensor in a manner that accumulates and records the sampled data sequentially. It then forms a subset within a unit of time based on a single aluminum substrate pressing operation, and finally forms a temperature database. The algorithm processing unit compares the N sampled temperature data within the subset using an algorithm formula, thereby identifying and filtering out low-temperature extreme values ​​and high-temperature extreme values. The algorithm formula for the algorithm processing unit is as follows: Tmin-i=min(T1, T2, T3...Ti); Tmax-j= max(T1, T2, T3…Tj); Where Tmin-i is the sampling temperature when the i-th temperature sensor reaches the low temperature extreme value; at this time, the algorithm processing unit feeds back a heating command to the resistance wire; Tmax-j is the sampling temperature when the j-th temperature sensor reaches the high temperature extreme value; at this time, the algorithm processing unit feeds back a cooling command to the resistance wire and the cooling fan. The data storage unit is used to record and store the temperature data of the signal receiving unit, and stores the data in the form of an Excel spreadsheet, with each single pressing of the aluminum substrate as a unit. At the same time, the temperature data information of the pressing of the aluminum substrate per unit quantity is defined as a tag and displayed on the page in the form of a tab page. Clicking on different tags displays and displays the hot pressing temperature status of the aluminum substrate for different quantities.
