Description

TECHNICAL FIELD

[0001] The utility model relates to copper clad plate production and manufacturing technology, especially a kind of packaging substrate pressing system. BACKGROUND

[0002] The substrate is the basic material for manufacturing PCB, and in general, the substrate is copper foil laminated plate, and single-sided and double-sided printed boards are manufactured on the substrate material-copper foil laminated plate (CCL) by selectively processing holes, electroless copper plating, electroplating copper, etching and other processes to obtain the required circuit pattern. Another type of multilayer printed board is also manufactured by using the inner core thin copper foil plate as the base, and the conductive pattern layer and the prepreg are alternately bonded together by one-time lamination to form 3 or more conductive pattern layers interconnected. It has the functions of conduction, insulation and support. The performance, quality, processability, manufacturing cost and manufacturing level of the printed board are largely dependent on the substrate material.

[0003] The existing substrate pressing system, as shown in Figure 1 has the following defects:

[0004] Firstly, when cooling (warming up), the press heat oil needs to circulate to continuously pass through the heat exchanger for continuous cooling (warming up), and the temperature difference ΔT is limited by the area of the heat exchanger, which is basically a constant value, and cannot be quickly cooled. When the temperature changes, hot oil and cold oil are mixed (especially at the initial stage and the end), in order to improve the temperature control accuracy, the energy consumption power demand in unit time is large, and the heat production capacity of the equipment is required to be high.

[0005] Secondly, when the amount of waste heat recovery is greater than the heat consumption, the heat recovered by waste heat recovery cannot be used up, which will cause the temperature of the hot oil in the storage tank to continuously rise and exceed the safety limit value.

[0006] Thirdly, when the outside air temperature is very high in summer, the high-temperature section is cooled, and the high-temperature water converted by cooling must be transferred to the external heat exchange and heat dissipation system (such as cooling tower) in time, and the problem of hot water after heat exchange easily damaging the heat exchange fins of the external heat exchange and heat dissipation system (such as cooling tower) will occur.

[0076] Embodiment one

[0077] As shown in Figure 2 , Figure 3 , Figure 4 The packaging substrate pressing system comprises a heat exchange group 1, a cold exchange group 2, a first valve 51, a second valve 52, a controller 8 and at least one press unit 3.

[0078] The heat exchange group 1, the cold exchange group 2, the first valve 51, the second valve 52, the third valve 53 and the press group 3 are connected by pipelines;

[0079] The heat exchange group 1 comprises a first tank 11 and a hot tank temperature sensor 81; the hot tank temperature sensor 81 is used to detect the temperature of the medium in the first tank 11;

[0080] The cold exchange group 2 comprises a third tank 13 and a cold tank temperature sensor 82; the cold tank temperature sensor 82 is used to detect the temperature of the medium in the third tank 13;

[0081] The press group 3 comprises a press 6, a press temperature sensor 63 and a third pump 43;

[0082] The press temperature sensor 63 is used to detect the temperature of the press 6;

[0083] The inlet of the press 6 is the inlet of the upper hot plate 61 and the lower hot plate 62, and the outlet of the press 6 is the outlet of the upper hot plate 61 and the lower hot plate 62;

[0084] The first valve 51 has an inlet connected to the outlet of the heated medium of the heat exchange group 1, and an outlet connected to the inlet of the third pump 43;

[0085] The outlet of the third pump 43 is connected to the inlet of the press 6;

[0086] The second valve 52 has an inlet connected to the outlet of the press 6, a first outlet connected to the first inlet of the first tank 11, and a second outlet connected to an inlet of the third tank 13;

[0087] The controller 8 is used to control the opening and closing of the first outlet and the second outlet of the second valve 52 according to the temperature of the press 6 and the temperature of the medium in the first tank 11.

[0088] In the packaging substrate pressing system of the first embodiment, the controller 8 controls the opening and closing of the first outlet and the second outlet of the second valve 52 according to the temperature of the press 6 and the temperature of the medium in the first tank 11. When the heat source of the heat exchange group 1 or the cold source of the cooling machine group 2 fails, the first tank 11 (hot oil tank) or the third tank 13 (cold oil tank) still has a certain heat retention function, the functional redundancy is good, the stability of the system can be greatly improved, and the temperature of the press 6 can be precisely controlled with high efficiency and energy saving.

[0089] Embodiment two

[0090] Based on the packaging substrate press system of embodiment one, when the temperature of the press 6 is raised, if the difference between the temperature of the press 6 and the temperature of the medium in the first tank 11 is not less than a first set temperature (for example, 10°C), the controller 8 controls the second valve 52 to make the medium flowing back from the hot plate of the press 6 to flow through the second outlet of the second valve 52 to the third tank 13 of the cold exchange group 2; when the difference between the temperature of the press 6 and the temperature of the medium in the first tank 11 is less than the first set temperature (for example, 10°C), the controller 8 controls the second valve 52 to make the medium flowing back from the hot plate of the press 6 to flow through the first outlet of the second valve 52 to the first tank 11 of the heat exchange group 1.

[0091] Preferably, the temperature of the press 6 is the temperature of the medium at the outlet of the hot plate of the press 6 or the temperature of the packaging substrate press material between the upper and lower hot plates of the press 6.

[0092] Preferably, the temperature of the medium in the first tank 11 is the temperature of the medium at the outlet of the first tank 11.

[0093] Preferably, the temperature of the medium in the third tank 13 is the temperature of the medium at the outlet of the third tank 13.

[0094] In the packaging substrate press system of embodiment two, when the temperature of the press 6 is raised, the heat of the medium comes from the medium in the first tank 11. During the process of raising the temperature of the press 6, the medium with high heat is connected to the third pump 43 through the first valve 51, enters the hot plate of the press 6, and then flows back to the first tank 11 from the hot plate through the first outlet of the second valve 52. When the temperature of the press 6 is raised, as the difference between the temperature of the press 6 and the set process temperature becomes smaller, the controller 8 correspondingly controls the rotation speed of the third pump 43 to be reduced and controls the opening degree of the first valve 51 and the second valve 52 to be reduced. At the beginning of raising the temperature of the press 6, there is a part of cold oil in the press 6 and the pipeline. At this time, when the difference between the temperature of the press 6 and the temperature of the medium in the first tank 11 is not less than a first set temperature (for example, 10°C), the medium flowing back from the hot plate of the press 6 flows through the second outlet of the second valve 52 to the third tank 13 of the cold exchange group 2. When it is detected that the difference between the temperature of the press 6 and the temperature of the medium in the first tank 11 is less than the first set temperature (for example, 10°C), the controller controls the opening degree of the first outlet of the second valve 52 to be increased to make the medium flow to the first tank 11 of the heat exchange group 1. In the packaging substrate press system of embodiment one, during the process of raising the temperature of the press 6, the cold medium can be ensured to flow back to the third tank 13 of the cold exchange group 2 and the hot medium can be ensured to flow back to the first tank 11 of the heat exchange group 1, so that the heat can be fully utilized without waste, and the energy efficiency can be greatly improved.

[0095] Embodiment three

[0096] Based on embodiment two, as shown in FIG. 2, the packaging substrate press system further comprises a third valve 53. Figure 3 、 Figure 4 The first outlet of the second valve 52 is connected to the inlet of the third valve 53.

[0099] The third valve 53 and the first valve 51 are proportional valves of the same type.

[0100] Preferably, when the temperature of the press 6 is to be raised, the controller 8 controls the rotation speed of the third pump 43, the proportional opening of the first valve 51 and the proportional opening of the third valve 53 according to the difference between the temperature of the press 6 and the set process temperature.

[0101] Preferably, when the temperature of the press 6 is to be raised, the rotation speed of the third pump 43 is positively correlated with the difference, and the proportional opening of the first outlet of the third valve 53 plus the proportional opening of the first outlet of the first valve 51 equals 1.

[0102] Preferably, when the temperature of the press 6 is to be maintained, and the temperature to be maintained is higher than the temperature of the medium in the third tank 13, the controller 8 controls the proportional opening of the first outlet of the third valve 53 and the proportional opening of the first outlet of the first valve 51 according to the temperature to be maintained, and the proportional opening of the first outlet of the third valve 53 plus the proportional opening of the first outlet of the first valve 51 equals 1, and controls the rotation speed of the third pump 43 according to the temperature to be maintained. The flow rates of the two valves can ensure temperature stability, so as to accurately maintain the temperature.

[0103] In the packaging substrate pressing system of the third embodiment, when the temperature of the press 6 is to be raised, the heat of the medium comes from the medium in the first tank 11. During the process of raising the temperature of the press 6, the medium with high heat passes through the first outlet of the first valve 51, enters the hot plate of the press 6 through the third pump 43, and then returns to the first tank 11 through the first outlet of the second valve 52 and the second outlet of the third valve 53. When the temperature of the press 6 is to be raised, as the difference between the temperature of the press 6 and the set process temperature becomes smaller, the controller 8 correspondingly controls the rotation speed of the third pump 43 to be reduced, and controls the proportional openings of the third valve 53 and the first valve 51, so as to accurately control the temperature of the press 6 and improve energy efficiency.

[0113] Preferably, when the temperature of the press 6 is to be lowered, and a large amount of heat needs to be absorbed, the controller 8 controls the proportional opening of the first outlet of the third valve 53 and the first valve 51 to gradually change at the same time, so that the medium from the press 6 returns to the first tank 11 or to the third tank 13.

[0114] Preferably, when the temperature of the press 6 is to be lowered, if the difference between the temperature of the medium at the outlet of the press 6 and the temperature of the medium in the first tank 11 is less than a first set temperature, the controller 8 controls the proportional opening of the second outlet of the third valve 53 to increase, thereby increasing the amount of medium returning to the first tank 11.

[0116] Preferably, when the temperature of the press 6 is to be lowered, if the difference between the temperature of the medium at the outlet of the press 6 and the temperature of the medium in the first tank 11 is greater than or equal to a first set temperature, the controller 8 controls the proportional opening of the first outlet of the third valve 53 to increase, and the proportional opening of the second outlet of the first valve 51 to increase, thereby increasing the amount of medium returning to the third tank 13.

[0117] Preferably, when the temperature of the press 6 is to be lowered, if the difference between the temperature of the medium at the outlet of the press 6 and the temperature of the medium in the first tank 11 is greater than a second set temperature (for example, 20°C, the temperature difference is large), the second set temperature is greater than the first set temperature, the controller 8 controls the first outlet of the second valve 52 to be closed and the second outlet to be opened, controls the first outlet of the fourth valve 54 to be opened, so that the medium flowing out of the press 6 is directly led to the third tank 13, and then to the press side inlet of the second heat exchanger 32, and then flows from the press side outlet of the second heat exchanger 32 to the fourth valve 54, and then to the third pump 43 and the press 6 to form a temperature lowering cycle.

[0119] The fifth embodiment

[0120] Based on the fourth embodiment, as shown in Figure 3 、 Figure 4 The packaging substrate pressing system further comprises a sixth pump 46.
