Description
Technical field
The present invention relates to freezing clamping device, in particular to a kind of samming freezing clamping device and its control method.
Background technique
It freezes clamping device (also known as cryogenic grip, Refrigerating suction cup etc.), is to utilize electrothermal refrigeration principle (also known as Peltier
Effect), frost by the face-to-face plate of refrigeration of cold and hot chip (also known as electric heating cooling element, semiconductor combinations piece etc.) and thereon
Medium carries out rapid refrigeration and the solid mode of ice carries out frost clamping to workpiece, can clamp conventional brace well and be difficult to clamp
Tiny precision workpiece, sheet workpiece, irregular shape workpiece etc., be widely used.Such as utility model patent " semiconductor freezing
Sucker ", application number: 201821743134.2, publication number: 208880564U, disclosed in semiconductor Refrigerating suction cup, be logical
The chill surface of semiconductor combinations piece is crossed using paltie effect, medium to conduction cooling plate and thereon carries out refrigeration frost, realizes work
Part clamping；Since semiconductor combinations piece is there are chill surface, that certainly exists heating face, therefore in the mistake of semiconductor combinations piece work
Cheng Zhong needs to take away the heat that semiconductor combinations piece heats face by radiating mode, just can guarantee that semiconductor combinations piece freezes
The cooling effect in face；And radiating flow passage add circulating cooling liquid be commonly use, preferred radiating mode.However, above-mentioned " semiconductor freezing
Sucker " used by radiating flow passage add the radiating mode of circulating cooling liquid, there is following deficiencies: when distribution is installed below in panel
More than two cold and hot chips when, the hot face of each chip is generating heat, and radiates, and when recycling cold liquid along dissipating
Hot flow path successively passes through and to first, second ..., and the cold and hot chip of n-th carries out when heat dissipation takes away heat, and the temperature of coolant liquid must
So can be higher and higher, heat dissipation effect gradually reduces, and the chip heat taken away is also fewer and fewer, just results in the chip of front in this way
Radiating, more, cooling effect is good, and corresponding positions of panels temperature is lower, and subsequent chip cooling is few, cooling effect is poor, corresponding
Positions of panels temperature is higher, in this way, panel and refrigerant thereon, the heat dissipation effect of different location is inconsistent, just deposits
In the temperature difference, refrigeration is uneven, influences clamping effect.Precision workpiece, either which kind of material will necessarily exist and expand with heat and contract with cold, is cold
The case where thermal deformation, when freezing clamping, if cryogenic temperature is uneven, it is easy to influence the precision of processing.Separately
Outside, uneven due to heat dissipation, lead to the uneven of freezing, while also influencing whether that freezing clamps temperature controlled precision,
Error is larger.There is also following deficiencies for current freezing clamping device: first is that, integral heat sink effect is poor, poor temperature uniformity, and two
It is that temperature control error is big, cannot achieve high accuracy temperature control and adjusting.Therefore, traditional samming freezes clamping device also
There are many unreasonable places, need to make improvements perfect.
Summary of the invention
In view of the above deficiencies, it the object of the present invention is to provide a kind of samming freezing clamping device and its control method, mentions
High integral heat sink effect realizes that the hot face heat dissipation of multiple cold and hot chips is consistent, guarantees panel and refrigerant difference position thereon
The cryogenic temperature set is uniform, and improves freezing and clamp temperature controlled precision.
The technical solution adopted by the present invention are as follows: a kind of samming freezing clamping device, including shell and lamina tecti (generally may be used also
To include bottom plate, as substrate element), the shell forms accommodating installation cavity, evenly distributed peace on the downside of the lamina tecti
Equipped with more than two cold and hot chips, the hot face in downside of each cold and hot chip is correspondingly arranged on cold water transition block, the cold water mistake
Crossing block includes cold water adapter cavity, cold water transition water inlet and cold water transition water outlet；
It further include being provided with into water circulating chilled water block and water outlet circulating chilled water block, the water inlet circulating chilled water block into water circulating chilled water
Runner, the water inlet circulating chilled water runner are connected with cooling water inlet, and the water inlet circulating chilled water runner corresponds to the every of same row
The cold water transition water inlet of a cold water transition block is provided with water inlet interface, and the water outlet circulating chilled water block is provided with water outlet cold water and follows
Circulation road, the water outlet circulating chilled water runner are connected with cooling water outlet, and the water outlet circulating chilled water runner corresponds to same row's
The cold water transition water outlet of each cold water transition block is provided with water outlet mouthpiece；
Further include more than two throttle valves, throttle valve setting in water inlet circulating chilled water block, and with water inlet circulating chilled water block
Each water inlet interface match, adjust water inlet circulating chilled water block water inlet interface and cold water transition block cold water transition water inlet
Conducting space, and then adjust enter cold water transition block in cold water flow.
Samming freezes the control method of clamping device, includes the following steps:
1) throttle valve is presetting: access power supply, and starting samming freezes clamping device, inputs preset voltage value, adjust each throttle valve,
And then the cold water inlet in each cold water transition block is adjusted, at the same time, it is corresponding every that lamina tecti is detected by hygrosensor
The temperature of the position of a cold and hot chip guarantees samming freezing folder so that the temperature of each position is consistent, and reaches preset temperature value
Hold the cryogenic temperature uniformity of device different location；
2) lead to during the job applications of samming freezing clamping device in the local location mounting temperature sensor of lamina tecti
The voltage value of access power supply is overregulated, and then adjusts the cooling effect of cold and hot chip, and cooperate the feedback temperature of temperature sensor,
Realize that the thermostatic of samming freezing clamping device is adjusted and controlled.
The invention has the following advantages that one, each cold and hot chip is correspondingly arranged on cold water transition block, carries out independent dissipate
Heat by heat-sink unit, good heat dissipation effect, and is easily adjusted, different location chip caused by avoiding traditional integration from radiating
Radiate inconsistent situation.Two, each cold water transition block is connected using water inlet circulating chilled water block and water outlet circulating chilled water block, as far as possible
The cold water of guarantee into each cold water transition block is the relatively uniform cold water (or other cold liquid) of the temperature of most original, guarantees to dissipate
While thermal effect, avoid traditional single cold water runner successively by chip cooling effect in front caused by each cold and hot chip
The problem of the good effect of the chip below difference of fruit, in this way, which just the equal of heat dissipation can be improved while further increasing heat dissipation effect
Even property.Three, each cold water transition block setting throttle valve is corresponded on water inlet circulating chilled water block, is adjusted section and is entered each cold water transition

2) lead to during the job applications of samming freezing clamping device in the local location mounting temperature sensor of lamina tecti
The voltage value of access power supply is overregulated, and then adjusts the cooling effect of cold and hot chip, and cooperate the feedback temperature of temperature sensor,
Realize that the thermostatic of samming freezing clamping device is adjusted and controlled.
