Abstract

The pressing mechanism includes a supporter, a pressing jig, and a temperature control mechanism, which is arranged between the supporter and the pressing jig. The first heat-exchanged fluid by the pressing jig in the first space is transported to the third space of the third temperature control unit by the transporter of the first temperature control unit of the temperature control mechanism, The first heat-exchanged fluid is hot and undergoes a second heat-exchanging with the first temperature control member of the second space of the second temperature control unit when flowing through the third space. The second heat-exchanged fluid in the third space is cooled down is injected into the first space by the transporter for heat dissipation. Thus, the temperature beside the pressing jig can be reduced, and the heat can be quickly dissipated to reduce the cost.

Description

Crimping mechanism and operating equipment

The present invention provides a crimping mechanism that saves energy costs for processing high-temperature fluids and improves heat dissipation efficiency.

Nowadays, please refer to Figures 1 and 2. After the electronic component 11 is manufactured, the operator uses a tester 12 to hold multiple electronic components 11 and transports them to an operating equipment (such as an electrical testing operating equipment or a pre-burning testing operating equipment) to perform testing operations. The tester 12 includes an electrically connected circuit board 121 and multiple test sockets 122. The test sockets 122 are used to hold and test the electronic components 11, and are equipped with an outer cover 123. The outer cover 123 covers the test sockets 122 to limit the electronic components 11. However, during the testing process of the electronic component 11, it will generate high temperature. In order to avoid excessive high temperature affecting the test quality, the tester 12 is equipped with multiple heat sinks 124 on the top of the outer cover 123 for heat dissipation.

Taking the pre-burning test operation equipment as an example, the working space 131 of the pre-burning furnace body 13 is provided with a plurality of layers of racks 132 for holding the tester 12 having a plurality of electronic components 11. One side of the pre-burning furnace body 13 is provided with an air inlet channel 133 for the gas processing device (not shown) to input gas with a preset temperature and for the gas to flow into the working space 131, so that the electronic components 11 can be pre-burned in a high temperature environment simulating future applications. Each of the testers 12 on several layers uses heat dissipation fins 124 to dissipate heat, and the high-temperature gas released by the heat dissipation flows into the working space 131. The large amount of high-temperature gas in the working space 131 then flows into the air outlet duct 134 set on the other side of the pre-calcination furnace body 13. The air outlet duct 134 transports the large amount of high-temperature gas to the gas processing device, and the gas processing device processes the large amount of high-temperature gas and cools it to a preset temperature before transporting the gas with the preset temperature back to the air inlet duct 133.

However, the large amount of high-temperature gas released from the heat sink fins 124 of dozens or hundreds of test sockets 122 into the working space 131 causes the ambient temperature around the test sockets 122 to exceed the originally preset ambient temperature. The large amount of high-temperature gas with excessive temperature is then transported to the gas processing device through the air outlet duct 134, so that the pre-burn test operating equipment must be equipped with a larger power gas processing device to cool down the large flow and excessive temperature gas to the preset temperature, resulting in considerable energy consumption and cost.

In addition, the gas treatment device with a relatively large power is relatively large in size, so that it occupies a considerable amount of space around the pre-burning test operation equipment, which is not conducive to space allocation.

The first object of the present invention is to provide a crimping mechanism, comprising at least one mounting device, at least one crimping fixture and at least one temperature control structure; the mounting device is used to assemble at least one temperature control structure, the temperature control structure comprises a first temperature control unit, a second temperature control unit and a third temperature control unit, the first temperature control unit is used to assemble the crimping fixture, and is provided with a first space having a conveyor, the conveyor can convey the fluid in the first space and perform the first heat exchange with the crimping fixture, the second space of the second temperature control unit is used to configure a first temperature control unit with a preset temperature, and the third temperature control unit is configured on the first temperature control unit. A third space is provided between the first temperature control unit and the second temperature control unit for conveying the fluid of the first heat exchange. The high-temperature fluid of the first heat exchange can be heat exchanged for the second time with the first temperature control unit of the second space during the flow in the third space. The first temperature control unit then uses the conveyor to convey the fluid of the second heat exchange and cooling in the third space into the first space for circulation. This can avoid the environment temperature around the crimping fixture from being too high. In particular, when a large number of temperature control structures are in operation at the same time, there is no need to configure a high-power fluid processing device, thereby effectively saving energy costs.

The second object of the present invention is to provide a crimping mechanism, whose temperature control structure can make the heat-exchanged and high-temperature fluid circulate in the first and third spaces to avoid dissipating outward, so as to effectively prevent the ambient temperature around the crimping fixture from being too high. There is no need to configure a large-volume fluid processing device, thereby effectively reducing the volume to facilitate the configuration of the surrounding space of the operating equipment.

According to the operation requirements, the first space of the first temperature control unit and/or the third space of the third temperature control unit is provided with at least one fin for heat dissipation.

In this embodiment, the crimping mechanism is configured with multiple layers of temperature control structures, each layer of the temperature control structure includes multiple first temperature control units, a second temperature control unit and multiple third temperature control units. The multiple first temperature control units are assembled below the multiple third temperature control units, and the second temperature control unit and the third temperature control unit are assembled on the pressure cylinder 24, so that the pressure cylinder 24 can drive the multiple first temperature control units, the second temperature control unit and the multiple third temperature control units to synchronously displace along the crimping axis in the working space 211 of the frame 21.

The first temperature control unit is provided with a plurality of first plates 251 to enclose a first space 252, and the first plate 251 located at the bottom is provided for assembling the press-fitting jig 22. Furthermore, the inner surface of the first plate 251 of the first temperature control unit is provided with a plurality of first fins 253 facing the first space 252. The first temperature control unit is provided with a conveyor, which is a fan 254, inside the first space 252. The fan 254 can blow the fluid in the first space 252, which is a gas, toward the first fin 253, and the first space 252 can output the high-temperature gas that has undergone the first heat exchange with the first fin 253 and the press-fitting jig 22 to the third temperature control unit.

The second temperature control unit is provided with a plurality of second plates 261 to enclose at least one second space 262; the first temperature control element is a liquid, and one side of the second space 262 is provided with an inlet 263 connected to a liquid conveying device (not shown) for inputting a liquid with a preset low temperature, and the liquid can be cooling water or a refrigerant; in this embodiment, the liquid is cooling water, and the inlet 263 is used for inputting cooling water with a preset low temperature, and the cooling water flows along the liquid flow path of the second space 262 from one side to the outlet 264 on the other side, and the outlet 264 is used to output the cooling water that has been heat exchanged.

In this embodiment, the third temperature control unit uses the second plate 261 of the second temperature control unit located at the bottom as the top plate, and configures an independent third plate 271A as the bottom plate. The second plate 261 and the third plate 271A are opposite to each other and are arranged in the X direction, and a plurality of third spaces 272 are separated by a plurality of third plates 271B between the two. Furthermore, a plurality of second fins 273 are provided on the second plate 261 and the third plate 271A facing the third space 272. The two sides of the third plate 271A of the third temperature control unit are assembled and connected to the pressure cylinder 24, and can be driven by the pressure cylinder 24 to move along the compression axis.

Based on the above, the third space 272 of the third temperature control unit and the first space 252 of the first temperature control unit are provided with a first flow channel and a second flow channel which are in communication. The first flow channel is used for the first heat exchange in the first space 252 and the high-temperature gas is output to the third space 272. The second flow channel is used for the second heat exchange in the third space 272 and the cooled gas is input into the first space 252. In this embodiment, the third temperature control unit is provided with a first flow channel 274 and a second flow channel 275 on the third plate 271A, which are connected to the third space 272 and the first space 252. The first flow channel 274 allows the gas in the first space 252 and subjected to the first heat exchange with the crimping fixture 22 to flow into the third space 272, and the second flow channel 275 allows the gas in the third space 272 and subjected to the second heat exchange with the cooling water to flow out to the first space 252, so that the first space 252, the third space 272, the first flow channel 274 and the second flow channel 275 form a circulating gas flow path, which can prevent the high-temperature gas from being dispersed outward in the working space 211 around the crimping fixture 22 after the first heat exchange.

Based on the above, the bottom surface of the third plate 271A of the third temperature control unit can be used to assemble a plurality of first temperature control units, so that the plurality of first temperature control units can be displaced synchronously with the third temperature control unit.

Based on the above, the second temperature control unit can be provided with a single second space 262, the area of which covers the tops of a plurality of third spaces 272, or the second temperature control unit can be configured with a relative number of second spaces 262 according to the number of third spaces 272. In this embodiment, the second temperature control unit is provided with a single second space 262, the area of which covers the tops of a plurality of third spaces 272, that is, the liquid flow path of the second space 262 covers the tops of a plurality of third spaces 272, so that cooling water can flow through the tops of a plurality of third spaces 272.

Please refer to Figures 5 to 7. A tester includes an electrically connected circuit board 31 and a plurality of test sockets 32. The test sockets 32 are provided with an outer cover 33 and are capable of holding and testing electronic components 34. In this embodiment, each layer of the rack 21 of the pre-burn test operation equipment is provided with a circuit board 31 having a plurality of test sockets 32 and electronic components 34. The plurality of test sockets 32 and the plurality of electronic components 34 on each layer are located in the working space 211 of the rack 21, and the test sockets 32 are located below the corresponding crimping fixtures 22.

Each layer of the pressing cylinder 24 of the pressing mechanism drives the first temperature control unit, the second temperature control unit, the third temperature control unit and the pressing fixture 22 to move downward along the pressing axis (such as the Z direction) synchronously, so that the pressing fixture 22 is pressed against the outer cover 33 of the test seat 32, and the heating element 23 is used to control the temperature of the electronic components 34 in the test seat 32 to perform the test operation.

During the test of the electronic component 34, the electronic component 34 transfers the high temperature to the first fin 253 through the crimping fixture 22. The first temperature control unit uses the fan 254 to blow the gas in the first space 252 downward, so that the gas exchanges heat with the first fin 253 and the crimping fixture 22 for the first time, so that the crimping fixture 22 dissipates heat and the electronic component 34 is kept at the preset test temperature while the test operation is performed in the test seat 32. The first heat exchanged and high-temperature gas in the first space 252 flows into the third space 272 from the first flow channel 274. Since the third space 272 is only for the first heat exchange gas in the first space 252 corresponding to the first temperature control unit to flow in, in the state of the first heat exchange gas with a small flow rate, cooling water is input through the inlet 263 on one side of the second space 262 of the second temperature control unit, and the cooling water flows along the liquid flow path of the second space 262 toward the outlet 264 on the other side. , so that the high-temperature gas in the third space 272 located below the second space 262 can not only exchange heat with the second fin 273 and generate turbulence to dissipate heat during the flow process, but also exchange heat with the cooling water in the second space 262 for a second time to cool down. The cooling water in the second space 262 that has exchanged heat flows out from the outlet 264; the gas in the third space 272 that has exchanged heat for the second time and cooled down is then sucked into the first space 252 by the fan 254 through the second flow channel 275, and blown toward the first fin 253 to dissipate heat.

Therefore, the gas of the first and second heat exchanges can circulate in the first space 252 and the third space 272, and the high-temperature gas of the first heat exchange will not flow out to the working space 211 of the rack 21, so as to avoid the ambient temperature around the crimping fixture 22 being too high. Not only is it unnecessary to configure a high-power and large-volume gas processing device (not shown), but it can effectively save energy costs and facilitate space configuration, and more quickly ensure that the test socket 32 and the electronic component 34 perform the test operation at the preset test temperature, thereby improving the test quality.
