Abstract
Description
Technical Field

[0002] With the development of economy and the progress of society, electronic components (such as chips) are widely used in various fields. Before electronic components are put into use, their reliability and stability under various ambient temperatures need to be tested. At present, the refrigeration system of the test sorting machine is connected to the shuttle through a pipeline. The refrigerant in the refrigeration system is transported to the flow channel of the shuttle through the pipeline, so that the shuttle can construct a preset temperature environment to meet the testing requirements of electronic components.
[0003] In order to complete the test of electronic components, the shuttle needs to reciprocate between the test station and the loading station or between the test station and the unloading station. Generally, the pipeline uses a bellows. Since the refrigeration system is fixed, when the shuttle reciprocates, the end of the bellows connected to the shuttle will also reciprocate with the shuttle. During this reciprocating motion, a certain part of the bellows will be repeatedly bent. The bellows is very prone to fatigue damage or breakage, which will lead to refrigerant leakage and require frequent replacement of the bellows. Utility Model Content

[0035] See also Figure 1 An embodiment of the present application provides a test sorting machine, including a material shuttle 200, a refrigeration system and a pipeline structure 100. The pipeline structure 100 is connected between the refrigeration system and the material shuttle 200. The refrigeration system is used to provide a refrigerant, the material shuttle 200 is used to carry and transport the tested product, and the pipeline structure 100 is used to transport the refrigerant between the refrigeration system and the material shuttle 200, so that the refrigerant flows through the refrigeration system to the flow channel of the material shuttle 200, so as to cool or heat the tested product carried on the material shuttle 200. It should be noted here that the connection between the pipeline structure 100 and the material shuttle 200 means that the pipeline structure 100 can not only mechanically connect the refrigeration system and the material shuttle 200, but also connect the flow channel in the material shuttle 200 with the flow channel of the refrigeration system. It should also be noted that, in addition to being able to direct the refrigerant in the refrigeration system to the flow channel of the material shuttle 200 for cooling or heating the product under test, the pipeline structure 100 can also re-direct the refrigerant after heat exchange in the flow channel of the material shuttle 200 to the refrigeration system, so that the refrigerant circulates back and forth between the refrigeration system and the material shuttle 200, thereby ensuring the cooling or heating effect of cooling or heating the product under test.
[0036] In some embodiments, the product under test is a chip or an intermediate product of a chip. It is conceivable that in other embodiments, the type of the product under test is not limited, such as other semiconductor products.
[0037] See also Figure 1-Figure 3The pipeline structure 100 includes a fixed seat 10, a connecting member 20 and a sliding member 30. The connecting member 20 and the sliding member 30 are sequentially installed on the fixed seat 10 along a first direction, the connecting member 20 is fixed on the fixed seat 10, and the sliding member 30 is slidably arranged on the fixed seat 10 along the first direction. The material shuttle 200 can move along the first direction relative to the fixed seat 10, so as to move between a loading station for loading the tested product and a testing station for testing the tested product, and / or between a testing station and a unloading station for unloading the tested product.
[0038] The pipeline structure 100 also includes a first tube 40 and a second tube 50. The two ends of the first tube 40 are connected to the connector 20 and the sliding member 30 respectively. One end of the first tube 40 connected to the connector 20 is used to connect to the refrigeration system. Specifically, the pipeline structure 100 also includes a connecting tube 80, and the first tube 40 is connected to the refrigeration system through the connecting tube 80. One end of the second tube 50 is connected to the sliding member 30 and one end of the first tube 40 connected to the sliding member 30, and the other end of the second tube 50 is connected to the material shuttle 200. In this way, the material shuttle 200 is connected to the refrigeration system through the first tube 40 and the second tube 50. It should be noted that when the second tube 50 is connected to the first tube 40, the two can not only achieve mechanical connection, but also achieve fluid communication. Similarly, when the first tube 40 is connected to the refrigeration system, or the second tube 50 is connected to the material shuttle 200, the two connected to each other can not only achieve mechanical connection, but also achieve fluid communication.
[0039] Continue reading Figure 1 , the first tube 40 includes at least two sub-tubes 41 that are movably connected. When the shuttle 200 moves in the first direction, the second tube 50 can follow the shuttle 200 to move in the first direction. Since the second tube 50 is connected to the sliding member 30, when the second tube 50 moves in the first direction, the sliding member 30 moves relative to the fixed seat 10 in the first direction. Since the two ends of the first tube 40 are respectively connected to the connecting member 20 and the sliding member 30, and the connecting member 20 is fixed to the fixed seat 10, the sliding member 30 pulls or pushes the first tube 40 when it moves in the first direction, and the sub-tubes 41 of the first tube 40 generate relative movement under the action of the sliding member 30, thereby changing the length of the first tube 40 in the first direction. That is, the length of the first tube 40 in the first direction can be adapted to the position of the shuttle 200 relative to the fixed seat 10 in the first direction.
[0040] In the pipeline structure 100 provided in the embodiment of the present application, when the shuttle 200 moves along the first direction, it can drive the second tube 50 to move along the first direction as a whole, so that the sliding member 30 is linked, and then the sub-tubes 41 of the first tube 40 are relatively moved, thereby changing the length of the first tube 40 in the first direction. In this way, during the movement of the shuttle 200 along the first direction, neither the first tube 40 nor the second tube 50 will be deformed. Compared with the method of using a corrugated tube in the prior art, each pipeline will not be repeatedly bent during the movement of the shuttle 200, and fatigue fracture is not likely to occur. The service life of each pipeline is increased, frequent replacement of the pipeline is avoided, and production efficiency is guaranteed.
[0041] The first tube 40 and the second tube 50 are both rigid tubes, which are hard and not easily deformed. Thus, when the shuttle 200 moves relative to the fixing seat 10 in the first direction, the first tube 40 and the second tube 50 are guaranteed not to deform, thereby preventing the first tube 40 and the second tube 50 from bending and breaking. Specifically, the first tube 40 and the second tube 50 are both copper tubes. Of course, in other embodiments, the material of the first tube 40 and the second tube 50 is not limited, as long as the material can ensure that the first tube 40 and the second tube 50 have a certain hardness and are not easily deformed.
[0042] In some embodiments, the fixed seat 10 is provided with a second slide rail 70, and the sliding member 30 is installed on the second slide rail 70. The second slide rail 70 is used to guide the sliding member 30 along the first direction, so as to ensure that the sliding member 30 always follows the material shuttle 200 to move along the first direction during the movement of the material shuttle 200 along the first direction. Of course, in some other embodiments, the pipeline structure 100 can also omit the second slide rail 70. In this case, a slide groove is provided on the fixed seat 10, and the sliding member 30 is arranged in the slide groove, and the slide groove can also play the role of guiding the sliding member 30 along the first direction.
[0043] In some embodiments, the pipeline structure 100 further includes a rotary joint 60, and two adjacent sub-tubes 41 are hinged through the rotary joint 60. The two sub-tubes 41 at the end are installed on the connector 20 and the sliding member 30 through the rotary joint 60, and are respectively connected to the refrigeration system and the second tube 50 through the rotary joint 60. That is, the two ends of the first tube 40 are respectively installed on the connector 20 and the sliding member 30 through a rotary joint 60, one end of the first tube 40 is connected to the refrigeration system through the rotary joint 60 at the end, and the other end of the first tube 40 is connected to the second tube 50 through the rotary joint 60 at the end. The second tube 50 can follow the shuttle 200 to move in the first direction, thereby driving the sliding member 30 to move in conjunction, and the sub-tube 41 rotates through the rotary joint 60, thereby changing the length of the first tube 40 along the first direction. In a specific embodiment, the first tube 40 includes two sub-tubes 41, at which time one end of a sub-tube 41 is arranged on the connector 20 through the rotary joint 60, and the end is connected to the connecting tube 80 through the rotary joint 60. The two sub-tubes 41 are hinged via a rotating joint 60, the other end of the other sub-tube 41 is disposed on the sliding member 30 via the rotating joint 60, and the end is connected to the second tube 50 via the rotating joint 60. In another specific embodiment, the number of sub-tubes 41 included in the first tube 40 is not limited.
[0044] In the above arrangement, the sub-tubes 41, the sub-tubes 41 and the connecting member 20 and the sliding member 30, and the second tube 50 and the sub-tube 41 are all connected via a rotary joint 60. In this way, when the material shuttle 200 moves along the first direction, the sub-tubes 41 rotate via the rotary joint 60 so that the length of the first tube 40 in the first direction is matched with the position of the material shuttle 200 on the fixed seat 10, thereby avoiding deformation of the first tube 40 and the second tube 50 when moving along the first direction.
[0045] It should be noted that, please continue to refer to Figure 2 The rotary joint 60 includes a first part 61 and a second part 62 that can generate relative rotation, and the two structures connected by the rotary joint 60 are respectively connected to the first part 61 and the second part 62 of the rotary joint 60. It should also be noted that the rotary joint 60 can not only realize the connection between pipelines, but also realize the flow communication between pipelines, and can ensure that the fluid will not leak during rotation.
[0046] Furthermore, since the rotary joint 60 connected to the connecting member 20 can rotate relative to the connecting member 20, a bearing is provided between the rotary joint 60 and the connecting member 20 to ensure smooth rotation of both.
[0047] Furthermore, a first slide rail is provided on the fixed seat 10, and the rotary joint 60 located between the two sub-tubes 41 has a motion track. The first slide rail is extended along the motion track, and the rotary joint 60 located between the two sub-tubes 41 is installed on the first slide rail, and the first slide rail is used to guide the rotary joint 60 along the motion track to prevent the rotary joint 60 from running off. It can be understood that in other embodiments, a slide groove can also be provided on the fixed seat 10 to guide the rotary joint 60 through the slide groove, which is not limited here.
[0048] It should be noted that the extension shape of the first slide rail is related to the motion track of the rotary joint between the two sub-tubes 41. Generally, the motion track of the rotary joint 60 between the two sub-tubes 41 is a curve, and the first rail extends along the curve.
[0049] In other embodiments, all sub-tubes 41 of the first tube 40 extend along the first direction and are mutually nested, and the second tube 50 can follow the shuttle 200 to move along the first direction, thereby driving the sliding member 30 to move in a linked manner, so that the sub-tubes 41 slide relative to each other, so as to change the length of the first tube 40 in the first direction. That is, the first tube 40 is a telescopic tube that can be telescopic in the first direction, and the sub-tubes 41 of the telescopic tube are mutually nested. When the second tube 50 follows the shuttle 200 to move in the first direction, the sliding member 30 also moves in the first direction. When the sliding member 30 moves in the first direction, the mutually nested parts of the sub-tubes 41 of the telescopic tube extend or retract, so as to change the length of the first tube 40 in the first direction.
[0050] Since the sub-tubes 41 are mutually socketed, when the material shuttle 200 moves along the first direction, the sub-tubes 41 slide relatively to each other, so that the length of the first tube 40 in the first direction is adapted to the position of the material shuttle 200 on the fixed seat 10, thereby avoiding deformation of the first tube 40 and the second tube 50 when moving along the first direction.
[0051] It should be noted that the relative sliding of the sub-tubes 41 will not cause leakage of the fluid.
[0052] In some embodiments, the material shuttle 200 is a long strip structure and its extension direction is parallel to the first direction. The second tube 50 is bent to connect with the material shuttle 200. Since the extension direction of the material shuttle 200 is parallel to the first direction, the second tube 50 is bent to connect with the material shuttle 200, which can reduce the space occupied by the pipeline structure 100 in the first direction.
[0053] The second tube 50 is bent along the first direction and the second direction. The first direction intersects the second direction. Specifically, the first direction is perpendicular to the second direction. In some specific embodiments, the fixing seat 10 is a rectangular plate-shaped structure, and the first direction is the length direction of the fixing seat 10 ( Figure 1The second direction is the width direction of the fixing seat 10 ( Figure 1 Of course, in some other implementations, the first direction and the second direction are not specifically limited.
[0054] In a specific implementation, continue to refer to Figure 1 , the material shuttle 200 is located at one end of the connecting member 20 and the sliding member 30 in the second direction, and the second tube 50 includes a first connecting tube 51 and a second connecting tube 52 connected to each other, the first connecting tube 51 extends along the second direction, and the second connecting tube 52 extends along the first direction. That is, at this time, the second tube 50 is a primary bending tube. The first connecting tube 51 is connected to the sliding member 30, and the second connecting tube 52 is connected to the material shuttle 200. In this way, the structure of the second tube 50 can be simplified, thereby simplifying the entire pipeline structure 100.
[0055] In some other embodiments, the second tube 50 may also be a multi-stage bending tube. For example, in one specific embodiment, the second tube 50 may also include a third connecting tube and a fourth connecting tube, the third connecting tube is connected to the second connecting tube and extends along the second direction, the fourth connecting tube is connected to the third connecting tube and extends along the first direction, and the fourth connecting tube is connected to the material shuttle 200. It should be noted that in some other specific embodiments, the number of bending stages of the second tube 50 is not limited.
[0056] It is conceivable that in other embodiments, the second tube 50 may also be arranged in other ways. For example, the second tube 50 is not a bent tube but a straight tube. As long as it can move along the first direction with the material shuttle 200 and is not easily deformed, it is not limited here.
[0057] Furthermore, in the second direction, the first tube 40 is located between the second tube 50 and the connecting member 20 and the sliding member 30 , so that the space occupied by the pipeline structure 100 in the second direction can be reduced.
[0058] The first tube 40 and the second tube 50 are both provided in two numbers, and the two first tubes 40 are used as the first input tube and the first output tube respectively, and the two second tubes 50 are used as the second input tube and the second output tube respectively. The first input tube is connected to the second input tube, and the first output tube is connected to the second output tube. The first input tube and the first output tube are both connected to the refrigeration system, the second input tube is connected to the input port of the shuttle 200, and the second output tube is connected to the output port of the shuttle 200. In this way, the refrigerant in the refrigeration system can enter the shuttle 200 through the first input tube and the second input tube in sequence, and the refrigerant in the shuttle 200 can flow back to the refrigeration system through the second output tube and the first output tube in sequence, so that the refrigerant can circulate back and forth between the refrigeration system and the shuttle 200.
[0059] It should be noted that when the first tube 40 is connected to the refrigeration system through the connecting tube 80, each first tube 40 is provided with a corresponding connecting tube 80. It should also be noted that when the test sorting machine has a plurality of shuttles 200, each shuttle 200 is provided with two first tubes 40 and a second tube 50, so that the refrigerant can circulate between the refrigeration system and each shuttle 200.
[0060] Further, the first input tube and the second input tube form an input tube group, and the first output tube and the second output tube form an output tube group. The input tube group and the output tube group are arranged in sequence in the third direction. The first direction, the second direction and the third direction intersect each other. Specifically, the first direction, the second direction and the third direction are perpendicular to each other. In a specific embodiment, when the fixing seat 10 is a rectangular plate-shaped structure, the third direction is the thickness direction of the fixing seat 10.
[0061] The above arrangement enables the input tube group and the output tube group to be stacked in the third direction, thereby avoiding relative interference between the input tube group and the output tube group when they are arranged on the same layer and move.
[0062] It should be noted that when the sub-tubes 41 of the first tube 40 are connected via the rotary joints 60, the input tube group and the output tube group are respectively provided with a set of rotary joint groups. The rotary joint group includes the rotary joints 60 provided between the sub-tubes 41, and also includes the rotary joints 60 provided on the connecting member 20 and the sliding member 30.
[0063] Another embodiment of the present application further provides a pipeline structure 100 included in the above-mentioned test sorting machine.
[0064] The pipeline structure 100 and the test sorting machine provided in the embodiment of the present application have the following beneficial effects:
[0065] 1. Both the first tube 40 and the second tube 50 are rigid tubes, and the first tube 40 includes at least two sub-tubes 41 that are movably connected. When the material shuttle 200 moves along the first direction, it can drive the second tube 50 to move along the first direction as a whole, so that the sliding member 30 is linked, and then the sub-tubes 41 of the first tube 40 generate relative movement, thereby changing the length of the first tube 40 in the first direction. In this way, during the movement of the material shuttle 200 along the first direction, the first tube 40 and the second tube 50 will not be deformed, and fatigue fracture is not likely to occur. The service life of each pipeline is increased, frequent replacement of the pipeline is avoided, and production efficiency is guaranteed.
[0066] 2. The adjacent sub-tubes 41 of the first tube 40 are connected by a rotating joint 60 to form a connecting rod mechanism. In this way, when the shuttle 200 moves along the first direction, the structures of the connecting rod mechanism rotate to make the length of the first tube 40 match the position of the shuttle 200 relative to the fixing seat 10 in the first direction. Compared with the method of using a corrugated tube in the prior art, the first tube 40 can be prevented from being deformed, thereby increasing the service life of the first tube 40.
[0067] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0068] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
