Abstract

The pressing mechanism includes a supporter, a pressing jig, and a temperature control mechanism, which is arranged between the support and the pressing jig. The first heat-exchanged gas with 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 uni. When the first heat-exchanged gas flows in the third spaced, it undergoes a second heat-exchanging with the first temperature control member of the second temperature control unit in the second space. The second heat-exchanged gas in the third space is cooled down and is discharged to the space beside the pressing jig. Thus, the temperature beside the pressing jig can be controlled to be not too high. Thereby, the cost of heat-dissipation can be reduced.

Description

Crimping mechanism and operating equipment

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

Today, as shown in Figures 1 and 2, after electronic components 11 are manufactured, they are placed in a tester 12 and transported to processing equipment (such as electrical testing equipment or burn-in testing equipment) for testing. The tester 12 includes an electrically connected circuit board 121 and multiple test sockets 122 for holding and testing the electronic components 11. The test sockets 122 are equipped with a cover 123 that covers the test sockets 122 and holds the electronic components 11 in place. However, during the testing process, the electronic components 11 generate high temperatures. To prevent excessive temperatures from affecting test quality, the tester 12 is equipped with multiple heat sinks 124 on the top of the cover 123 to dissipate heat.

Taking the pre-burning test 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 a tester 12 with a plurality of electronic components 11; an air inlet duct 133 is provided on one side of the pre-burning furnace body 13 for a gas treatment device (not shown) to input gas with a preset temperature and allow the gas to flow into the working space 131, so that the electronic components 11 can be pre-burned in a high temperature environment that simulates future applications; and then 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-furnace body 13. The air outlet duct 134 transports the large amount of high-temperature gas to the gas processing device, which 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 workspace 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. As a result, the pre-burn test operation equipment must be equipped with a larger-power gas processing device to cool down the large flow and high temperature gas to the preset temperature, resulting in considerable energy consumption and cost.

Furthermore, the larger the power of the gas treatment equipment, the larger the volume. This occupies a considerable amount of space around the pre-burn test equipment, which is not conducive to space allocation.

A first object of the present invention is to provide a crimping mechanism comprising at least one mounting device, at least one crimping jig, and at least one temperature control structure. The mounting device is configured to receive the at least one temperature control structure, which comprises a first temperature control unit, a second temperature control unit, and a third temperature control unit. The first temperature control unit is configured to receive the crimping jig and has a first space containing a conveyor capable of discharging gas within the first space for primary heat exchange with the crimping jig. The second temperature control unit is configured to have a second space for accommodating the first temperature control unit. The third temperature control unit is located between the first and second temperature control units and provides a third space for the conveyor to input the gas for the first heat exchange. As the gas flows through the third space, it undergoes a second heat exchange with the first temperature control unit in the second space. The third space then discharges the gas, which has undergone the second heat exchange and has been cooled, into the surrounding environment of the press-fitting fixture or the external environment of the press-fitting mechanism. This prevents the ambient temperature around the press-fitting fixture from rising too high. This eliminates the need for high-power gas processing equipment, especially when dozens or hundreds of temperature control mechanisms are operating simultaneously, effectively saving energy costs.

A second objective of the present invention is to provide a crimping mechanism in which the secondary heat exchange and cooling gas discharged from the temperature control structure can effectively prevent the ambient temperature around the crimping fixture from being too high, eliminating the need for a high-power and large gas processing device, thereby effectively reducing the volume and facilitating the space surrounding the operating equipment.

A third object of the present invention is to provide an operating apparatus comprising a rack, at least one crimping mechanism of the present invention, and a central control device; the rack being provided with at least one support frame for supporting at least one tester; at least one crimping mechanism of the present invention being mounted on the rack for crimping and temperature-controlling the tester; and the central control device for controlling and integrating the movement of the crimping mechanism to perform automated operations.

To help you better understand this invention, we will provide you with a better understanding of this invention by providing a preferred embodiment with accompanying drawings.

Referring to Figures 3 and 4, the present invention's crimping mechanism is applied to an operating device, which can be electrical testing equipment or burn-in testing equipment for electronic components. The operating device includes a rack, at least one present invention crimping mechanism, and a central control device (not shown). The rack is equipped with at least one support frame for holding at least one tester. The at least one present invention crimping mechanism is mounted on the rack and includes at least one mounting device, at least one temperature control structure, and at least one crimping fixture for crimping and temperature-controlling the tester. The central control device controls and integrates the crimping mechanism's movements to perform automated operations.

Depending on the work requirements, the operating equipment can be equipped with one or more of the present crimping mechanisms. In this embodiment, the operating equipment is electronic component burn-in test equipment. A rack 21 is constructed of multiple frames to form a workspace 211. At least one support frame 213 is positioned between two side frames 212 arranged in the Z direction. The support frame 213 can be a straight-line frame, an L-shaped frame, a machine plate, or a support plate, etc., for supporting at least one tester (not shown). In this embodiment, multiple layers of support frames 213 are positioned on the inner surfaces of the two side frames 212, each arranged in pairs. The two opposing support frames 213 on each layer are arranged in the X direction.

Depending on the operating requirements, the frame 21 can be equipped with at least one second actuator (not shown) to drive the support frame 213 to move along the compression axis (e.g., the Z direction); that is, the support frame 213 supports the tester, and the second actuator can drive the support frame 213 and the tester to move in the Z direction toward the compression fixture.

According to the working requirements, if the pre-burning test working equipment needs to flow hot air of the required preset temperature into the working space 211, an air inlet duct (not shown) and an air outlet duct (not shown) communicating with the working space 211 can be configured on both sides of the rack 21. This is also possible and is not limited to this embodiment.

The crimping mechanism of the present invention is assembled on the frame 21 and includes at least one mounting device, at least one crimping fixture, and at least one temperature control structure.

At least one mount is configured to be fixed or movable. For example, the mount can be a fixed frame of a transport vehicle or a fixed frame 21 of the burn-in test equipment. For example, the mount can be a movable transfer arm of electrical test equipment or a movable frame of the burn-in test equipment. As mentioned above, the mount can be a standalone frame, a transfer arm, or a side frame 212 of the frame 21. In this embodiment, the mount is a side frame 212 of the fixed frame 21 of the burn-in test equipment, and the side frame 212 is configured in the Z direction.

At least one crimping jig 22 is provided for crimping electronic components. Depending on the operation requirements, the crimping jig 22 can perform the crimping operation, or it can be equipped with at least one exhaust unit (not shown) for performing the transfer and crimping operations of the electronic components. In this embodiment, the crimping jig 22 can perform the crimping operation of the electronic components.

Depending on operational requirements, the crimping mechanism further includes at least one second temperature control unit, mounted on the crimping jig 22, to control and adjust the electronic component's preset test temperature. For example, if the electronic component has not reached the preset test temperature, the second temperature control unit can be activated to raise or lower the test temperature. If the electronic component has reached the preset test temperature, the second temperature control unit can be deactivated. Furthermore, the second temperature control unit can be mounted between the temperature control structure and the crimping jig 22, or mounted within or at a suitable location within the crimping jig 22. As mentioned above, the second temperature control unit can be a heater, a cooling chip, or a temperature control seat containing fluid. In this embodiment, the second temperature control unit is a heater 23, which is disposed within the crimping jig 22.

At least one temperature control structure is assembled on the mount, including at least one first temperature control unit, at least one second temperature control unit, and at least one third temperature control unit; the first temperature control unit is used to assemble the compression jig 22 and is provided with a first space having at least one conveyor, which can output the gas in the first space and undergo a first heat exchange with the compression jig 22; the second temperature control unit is provided with a second space for configuring the first temperature control unit; the third temperature control unit is arranged between the first temperature control unit and the second temperature control unit and is provided with a third space for the conveyor to input the gas for the first heat exchange, the gas for the first heat exchange can undergo a second heat exchange with the first temperature control unit in the second space, and the third space discharges the gas that has undergone the second heat exchange and has been cooled.

According to the operation requirements, the conveyor can be a fan or a suction pump, etc., for inputting or outputting the gas into or out of the first space or the third space, and is not limited to this embodiment.

Depending on the operation requirements, the first temperature control element can be liquid, gas or a cooling chip, etc., and is not limited to this embodiment.

Depending on operational requirements, the press-fit mechanism further includes at least one first actuator, mounted on a mount to drive the temperature-control structure along the press-fit axis (e.g., the Z-axis). Furthermore, the first actuator can be a linear motor, a cylinder, or a combination of a motor and at least one transmission assembly, such as a pulley assembly or a screw-screw assembly. In this embodiment, the press-fit mechanism comprises multiple layers of first actuators arranged on the inner surfaces of the two side frames 212 of the frame 21. The two opposing first actuators on each layer are cylinders 24, arranged in the Z-direction.

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 are provided with at least one fin for heat dissipation.

In this embodiment, the pressing mechanism is configured with multiple layers of temperature control structures, and 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 units and the third temperature control units 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 pressing axis in the working space 211 of the frame 21.

The first temperature control unit is equipped with a plurality of first plates 251 to enclose a first space 252. The first plate 251 at the bottom is used to assemble the press-fitting jig 22. The first space 252 allows for the flow of external air. Furthermore, the inner surface of at least one first plate 251, facing the first space 252, is provided with a plurality of first fins 253. The first temperature control unit is equipped with at least one conveyor, a fan 254, within the first space 252. The fan 254 is capable of discharging air from the first space 252 for the initial heat exchange with the press-fitting jig 22.

The second temperature control unit is located above the first temperature control unit and is provided with a plurality of second plates 261 to enclose at least one second space 262. The first temperature control unit is a liquid. The second space 262 is provided with an inlet 263 and an outlet 264. The inlet 263 is for inputting a liquid with a preset temperature. The liquid can be cooling water or a refrigerant. In this embodiment, the liquid is cooling water. The inlet 263 on one side of the second space 262 is for inputting cooling water with a preset low temperature. The cooling water flows along the liquid flow path of the second space 262 toward the outlet 264 on the other side. The outlet 264 is for outputting the cooling water that has undergone heat exchange. The two sides of the plurality of second plates 261 of the second temperature control unit are assembled and connected to the cylinder 24, and the cylinder 24 can drive the plurality of second plates 261 to move along the axial direction of the press connection.

The third temperature-control unit is located between the first and second temperature-control units, and is provided with a plurality of third plates 271A, 271B, etc. to enclose at least one third space 272. However, the third temperature-control unit can be configured with an independent third plate as the top plate, or with the second plate 261 of the second temperature-control unit located at the bottom as the top plate. 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 is configured with another independent third plate 271A as the bottom plate. The second plate 261 and the third plate 271A are arranged vertically opposite each other and in the X direction, and a plurality of third plates 271B are used between them to separate the plurality of third spaces 272. Furthermore, the second plate 261 and the third plate 271A are provided with a plurality of second fins 273 on the side facing the third space 272. The third plate 271A of the third temperature control unit is assembled and connected to the cylinder 24 on both sides and can be driven by the cylinder 24 to move along the axial direction of the press connection.

The third plate 271A of the third temperature control unit can serve as the top plate of the first temperature control unit. The third plate 271A is provided with at least one first opening 274 connecting the first space 252 and the third space 272. The first opening 274 is used for the fan 254 of the first temperature control unit to output the gas of the first heat exchange in the first space 252 to the third space 272. Furthermore, at least one second opening 275 is provided on the third plate 271A and/or the third plate 271B, connecting the third space 272 and the surrounding environment of the press-fitting jig 22 (or/and the external environment of the rack 21). The second opening 275 is used to exhaust the gas generated by the second heat exchange in the third space 272. In this embodiment, the third temperature-control unit is provided with multiple second openings 275 on the third plate 271A, connecting the third space 272 and the external environment of the press-fitting jig 22 (i.e., the working space 211 of the rack 21), to exhaust the gas generated by the second heat exchange and cooling in the third space 272. As described above, the bottom surface of the third plate 271A of the third temperature-control unit can be mounted with multiple first temperature-control units, allowing the multiple first temperature-control units to move synchronously with the third temperature-control unit.

As described above, the second temperature-control unit can be provided with a single second space 262, the area of which covers the tops of multiple third spaces 272. Alternatively, the second temperature-control unit can be provided with a corresponding number of second spaces 262 based on 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 multiple third spaces 272. In other words, the liquid flow path of the second space 262 covers the tops of multiple third spaces 272, allowing cooling water to flow through the tops of the multiple third spaces 272.

Referring to Figures 5 through 7, a tester includes an electrically connected circuit board 31 and multiple test sockets 32. The test sockets 32 are equipped with covers 33 and are capable of holding and testing electronic components 34. In this embodiment, each shelf 213 of the rack 21 of the burn-in test equipment is configured to hold a circuit board 31 with multiple test sockets 32 and electronic components 34. Each layer of multiple test sockets 32 and multiple electronic components 34 is located in the working space 211 of the rack 21, with the test sockets 32 positioned below the corresponding press-fit fixture 22.

Each level of the press-fit mechanism's press cylinders 24 drive the first, second, and third temperature-control units, along with the press-fit fixture 22, to synchronously move downward along the press-fit axis (e.g., the Z direction). This allows the press-fit fixture 22 to press-fit against the outer cover 33 of the test socket 32. The heater 23 then controls the temperature of the electronic components 34 within the test socket 32 to perform the test operation.

During the testing process of the electronic component 34, the electronic component 34 transfers high temperature to the first fin 253 through the press-fit fixture 22. The first temperature control unit uses the fan 254 to draw air into the first space 252 and into the first fin 253. The high-temperature gas undergoes the first heat exchange with the press-fit jig 22 and is transported through the first port 274 to the third space 272 of the third temperature-controlled unit. This dissipates heat from the press-fit jig 22 and maintains the electronic component 34 at the preset test temperature while the test operation is performed within the test socket 32. Since the third space 272 of the third temperature-controlled unit only allows the first heat exchange gas from the corresponding first space 252 of the first temperature-controlled unit to flow in, cooling water is introduced through the inlet 263 on the side of the second space 262 of the second temperature-controlled unit while the first heat exchange gas is flowing at a low flow rate. The cooling water flows along the liquid flow path of the second space 262 toward the outlet 264 on the other side. During the flow process, the high-temperature gas in the third space 272 below the second space 262 undergoes the primary heat exchange and not only exchanges heat with the second fins 273, generating turbulence and dissipating heat, but also undergoes a secondary heat exchange with the cooling water in the second space 262, cooling the gas. The cooling water in the second space 262 that has undergone the secondary heat exchange flows out of the outlet 264. The gas in the third space 272, which has undergone the secondary heat exchange and has been cooled, is then discharged through the second port 275 to the ambient space surrounding the press-fitting jig 22 (i.e., to the working space 211 of the rack 21) or to the outside of the working equipment.

Therefore, the crimping mechanism utilizes a temperature control structure to prevent the ambient temperature around the crimping fixture 22 from being too high. This not only eliminates the need for a high-power and bulky gas handling device (not shown), but also effectively saves energy costs and facilitates space allocation. It also more quickly ensures that the test socket 32 and electronic component 34 perform testing operations at the preset test temperature, thereby improving test quality.
