Description

Technical Field

[0001] This utility model relates to the field of testing and sorting equipment technology, and in particular to a crimping device and a testing and sorting machine. Background Technology

[0002] Before leaving the factory, electronic components (such as chips) need to undergo performance testing, which is generally performed on a test sorting machine. The test sorting machine has a crimping device. When testing electronic components, the crimping head picks up the electronic components and crimps them onto the test socket for testing.

[0003] The crimping device has an airflow channel. When the gas flows through the airflow channel, it exchanges heat with the crimping head of the device, thereby controlling the temperature of the crimping head and, consequently, the temperature of the electronic components in contact with the crimping head. In traditional technology, the gas in the airflow channel is blown directly from the crimping head to the outside. This method of blowing the gas directly from the crimping head to the outside not only easily leads to gas backflow but also fails to insulate the crimping head, resulting in poor temperature control of the crimping head.

[0007] The pressure head includes a connecting part, an air outlet part, and a pickup part connected sequentially along the first direction; the connecting part and the air outlet part are both disposed in the receiving cavity, and the pickup part passes through the through hole and exits the receiving cavity; the housing is provided with an air inlet channel, and the connecting part and the air outlet part form an air outlet channel communicating with the air inlet channel;

[0008] The cover also has a first surface connecting the first end face and the second end face, and the first surface is provided with a first exhaust hole communicating with the air outlet channel;

[0009] When the airflow passes through the air outlet channel, it can exchange heat with the pressure head to transfer heat to the electronic components picked up by the pickup unit.

[0010] In one embodiment, the air outlet of the air outlet channel is located at the end of the air outlet portion away from the connecting portion;

[0011] The cover includes a first part and a second part that are connected to each other. The first part is connected to the shell, and the second part forms a second end face on the surface of the second part away from the first part along the first direction.

[0012] The first vent is located on the side of the second part away from the first part.

[0013] In one embodiment, the pressure head includes a central portion and a peripheral portion, the peripheral portion being disposed outside the central portion around an axis extending along the first direction;

[0014] The middle portion and the outer portion form the connecting portion and the air outlet portion, the remaining portion of the middle portion forms the pickup portion, a vacuum path is formed in the middle portion, and the air outlet channel is located in the outer portion.

[0015] In one embodiment, the air outlet channel includes a first channel and a second channel, wherein the first channel is disposed in the connecting portion and the second channel is disposed in the air outlet portion;

[0016] The second channel includes multiple sub-channels, which are arranged sequentially at intervals around the axis, and each sub-channel extends along the first direction.

[0017] In one embodiment, the peripheral portion has a stepped surface at one end near the pickup portion along the first direction, and the air outlet of the air outlet channel is located on the stepped surface;

[0018] and / or

[0019] The peripheral portion has an outer peripheral surface surrounding the axis, and the air outlet of the air outlet channel is located on the outer peripheral surface.

[0020] In one embodiment, there are multiple first exhaust holes, which are arranged in an arc around an axis extending along the first direction and spaced apart sequentially.

[0021] In one embodiment, the pressure head further includes an overlapping portion connected to the air outlet and located within the receiving cavity, the overlapping portion fitting against the cavity wall of the receiving cavity and surrounding the periphery of the through hole.

[0022] In one embodiment, the second end face is provided with a second exhaust hole, which is connected to both the exhaust channel and the first exhaust hole.

[0023] In one embodiment, the second end face is provided with a plurality of second exhaust holes, which are arranged sequentially at intervals around the through hole.

[0024] A testing and sorting machine includes a feeding device, a conveying device, a testing seat, a receiving device, and a pressing device as described above;

With this structural arrangement, the connecting structure not only serves to insulate the pressure head, but also effectively prevents gas backflow and ensures stable pressure head temperature because the airflow is ultimately discharged through the first exhaust port.

[0045] See Figure 1 and Figure 2 One embodiment of this application provides a crimping device 100, which is used to pick up an electronic component 400 and crimp the picked-up electronic component 400 onto a test socket 200, whereby the test socket 200 tests the electronic component 400. Optionally, the electronic component 400 is a chip. Of course, in other embodiments, the type of electronic component 400 is not limited; for example, the electronic component 400 can also be a transistor or a diode, etc.

[0046] See Figure 3 The crimping device 100 includes a connecting structure 10 and a crimping head 20. The crimping head 20 is connected to the connecting structure 10 and has a pickup part 21 for picking up electronic components 400. The connecting structure 10 is connected to a driving assembly, which drives the connecting structure 10 to move, causing the pickup part 21 to crimp the picked-up electronic components 400 onto the test socket 200 for testing. In some embodiments, the crimping device 100 includes the aforementioned driving assembly, meaning the driving assembly is part of the crimping device 100. The driving assembly of the crimping device 100 drives the connecting structure 10 to move, and the connecting structure 10 drives the pickup part 21 to move, crimping the electronic components 400 onto the test socket 200. In other embodiments, the driving assembly can also be an external structure of the crimping device 100, meaning an external driving assembly drives the connecting structure 10 to move, crimping the electronic components 400 onto the test socket 200.

[0047] The drive component is connected to the robotic arm, which can drive the drive component to move. The drive component drives the pressing device 100 to move, so as to transfer the electronic component 400 from one position to another, which facilitates the testing of the electronic component 400.

[0048] See Figure 3 and Figure 4 The connecting structure 10 includes a housing 11 and a cover 12, which together form a receiving cavity 13. (See attached image) Figures 4-6 The cover 12 is along the first direction ( Figure 4 The first direction (in the Z direction) has a first end face 121 and a second end face 122 at its two ends. The first end face 121 is connected to the housing 11, and the second end face 122 has a through hole 129 communicating with the receiving cavity 13. Specifically, the first direction is parallel to the pressing direction in which the pressing device 100 presses the electronic component 400 onto the test base 200. The pressing head 20 also includes a connecting part 22 and an air outlet 23, which are arranged sequentially along the first direction. The connecting part 22 and the air outlet 23 are both located inside the receiving cavity 13, and the picking part 21 passes through the through hole 129 to exit the receiving cavity 13. The connecting structure 10 protects the connecting part 22 and the air outlet 23, and the picking part 21 passes through the through hole 129 to exit the receiving cavity 13 for easy handling of the electronic component 400.

[0049] Continue reading Figure 2The housing 11 is provided with an air inlet channel 111, and an air outlet channel 24 is formed on the connecting part 22 and the air outlet part 23, which communicates with the air inlet channel 111. The cover 12 also has a first surface 123 connecting the first end face 121 and the second end face 122, and the first surface 123 is provided with a first exhaust hole 124 communicating with the air outlet channel 24. When the cover 12 is cylindrical, the first surface 123 is the outer peripheral surface of the cover 12.

[0050] When the airflow flows through the outlet channel 24, it can exchange heat with the pressure head 20 to transfer heat to the electronic component 400 picked up by the pickup unit 21. Optionally, the airflow flowing through the inlet channel 111, the outlet channel 24, and the first exhaust port 124 can be either hot or cold air. When the airflow is hot, the temperature of the pressure head 20 increases after exchanging heat with it; when the airflow is cold, the temperature of the pressure head 20 decreases after exchanging heat with it. Generally, the crimping device 100 also includes a heating element disposed inside the pressure head 20 for heating the pressure head 20. In this case, the cold airflow and the heating element control the temperature of the pressure head 20 through a hot-cold confrontation, thereby achieving precise temperature control of the electronic component 400.

[0051] In the above configuration, the air outlet channel 24 inside the pressure head 20 is connected to the air source through the air inlet channel 111 on the housing 11. Compared to the method of connecting the air outlet channel 24 to the air source through copper pipes and corrugated pipes, this frees up internal space of the machine and reduces the use of pipelines, which not only reduces costs but also reduces the risk of leakage caused by repeated bending of pipelines. Furthermore, since the connecting part 22 and the air outlet 23 are located inside the receiving cavity 13, that is, the housing 11 and the cover 12 are wrapped around the connecting part 22 and the air outlet 23, the air outlet channel 24 opened in the connecting part 22 and the air outlet 23 is located inside the receiving cavity 13. After the airflow flows through the air outlet channel 24 and exchanges heat with the pressure head 20, it is discharged through the first exhaust port 124. With this structural configuration, the connecting structure 10 not only serves to insulate the pressure head 20, but also effectively prevents gas backflow and ensures the temperature stability of the pressure head 20, since the airflow is finally discharged through the first exhaust port 124.

[0052] Meanwhile, during the process of the pressure head 20 picking up and placing electronic components 400, the airflow can be controlled to continuously flow through the air outlet channel 24 to exchange heat with the pressure head 20. Since the first exhaust port 124 is located on the first surface 123 of the cover 12 connecting the first end face 121 and the second end face 122, the airflow blowing out from the first exhaust port 124 will not directly blow onto the electronic components 400, making it less likely for the electronic components 400 to fall off the pickup part 21, thus ensuring the picking and placing effect. Because the airflow continuously flows through the air outlet channel 24 to exchange heat with the pressure head 20 during the picking and placing of electronic components 400, the problem of the pressure head 20 exchanging heat with the surrounding environment and warming up will not occur, ensuring stable temperature control of the electronic components 400, thereby ensuring accurate test results.

[0053] Specifically, the connecting structure 10 is made of a thermally insulating material with low thermal conductivity to insulate the pressure head 20, reducing heat exchange between the warm gas inside the pressure head 20 and the external environment, thereby reducing energy loss. More specifically, the airflow from the first exhaust port 124 is parallel to the plane where the electronic component 400 is located. This ensures that the airflow does not blow directly onto the electronic component 400, thus preventing the electronic component 400 from falling off the pickup section 21 and ensuring the effective picking and placing of materials.

[0054] In some embodiments, see further reference. Figure 3 The air outlet 241 of the air outlet channel 24 is located at the end of the air outlet 23 away from the connecting part 22 along the first direction. (Continue reading...) Figure 5 The cover 12 includes a first part 125 and a second part 126 connected to each other. The first part 125 is connected to the shell 11. The surface of the second part 126 away from the first part 125 along a first direction forms a second end face 122. A first exhaust port 124 is provided on the side of the second part 126 away from the first part 125. An exhaust port 241 is located at one end of the exhaust channel 24 near the first exhaust port 124. Airflow in the exhaust channel 24 flows out through the exhaust port 241 and then flows to the first exhaust port 124 for discharge. If the end face of the second part 126 connected to the first part 125 along the first direction is defined as the third end face, then the side face is the surface connecting the second end face 122 and the third end face.

[0055] Since the air outlet 241 of the air outlet channel 24 is located at the end of the air outlet 23 away from the connecting part 22, and the first exhaust port 124 is located on the side of the second part 126 away from the first part 125, the path of the air outlet channel 24 can be extended, and the heat exchange time between the airflow and the pressure head 20 can be increased under the same airflow speed, thereby improving the heat exchange effect between the airflow and the pressure head 20, and thus ensuring the temperature control effect of the electronic components 400.

[0056] It is conceivable that in other embodiments, the vent 241 may also be located at other positions on the vent portion 23, such as at one end of the vent portion 23 near the connecting portion 22 along the first direction, which is not limited here. Of course, the first exhaust vent 124 may also be located at other positions on the cover 12, such as at one end of the second portion 126 near the first portion 125 along the first direction, which is also not limited here.

[0057] In some embodiments, see Figure 7 and Figure 8The pressure head 20 includes a central portion 25 and a peripheral portion 26. The peripheral portion 26 is disposed around the central portion 25 along an axis extending in a first direction; that is, the peripheral portion 26 wraps around the central portion 25 in the direction of its circumference around the axis. It should be noted that the peripheral portion 26 may wrap around a portion of the central portion 25 or completely enclose the central portion 25. In some specific embodiments, the peripheral portion 26 wraps around a portion of the central portion 25. In this case, the portion of the central portion 25 wrapped by the peripheral portion 26 and the peripheral portion 26 together form a connecting portion 22 and an air outlet 23. The remaining portion of the central portion 25 not wrapped by the peripheral portion 26 forms a pickup portion 21. A vacuum passage 251 is formed within the central portion 25, and an air outlet channel 24 is disposed within the peripheral portion 26. By including the central portion 25 and the peripheral portion 26 in the pressure head 20, the opening of the vacuum passage 251 and the air outlet channel 24 is facilitated.

[0058] It should be noted that, since both the connecting part 22 and the air outlet 23 of the pressure head 20 are located in the connecting structure 10, a connecting air passage 112 is provided on the connecting structure 10 to enable the connection between the vacuum passage 251 and the vacuum pumping equipment (see [reference]). Figure 4 The connecting air passage 112 is used to connect the vacuum air passage 251 and the vacuum equipment.

[0059] Continue reading Figure 2 The air outlet passage 24 includes a first passage 242 and a second passage 243. The first passage 242 is located at the connecting part 22, and the second passage 243 is located at the air outlet part 23. (Continue reading) Figure 4 and see Figure 9 and Figure 10 The second channel 243 includes multiple sub-channels 2431, which are arranged sequentially at intervals around the axis, and each sub-channel 2431 extends along the first direction. Specifically, the vacuum passage 251 extends along the first direction, and the multiple sub-channels 2431 are arranged sequentially at intervals around the vacuum passage 251.

[0060] With the above configuration, the airflow enters the first channel 242 through the air intake channel 111, and then flows through the first channel 242 into multiple spaced sub-channels 2431. In this way, the airflow can exchange heat with the pressure head 20 in multiple sub-channels 2431, thereby improving the uniformity of heat exchange.

[0061] Furthermore, the multiple sub-channels 2431 have the same extension length and cross-sectional area along the first direction, and are evenly spaced around the axis, so that the airflow can be evenly distributed to the multiple sub-channels 2431, thereby further improving the uniformity of heat exchange.

[0062] In some embodiments, the air intake passage 111 is not located on the end face of the housing 11, but rather on the side of the housing 11, in order to reduce the flow path of the airflow in the air intake passage 111. Optionally, see [further details omitted]. Figure 4The intake passage 111 is along the second direction ( Figure 4 The first channel 242 extends in the X direction. The first direction intersects the second direction, specifically, the first direction is perpendicular to the second direction. In order to communicate with the intake channel 111, the first channel 242 includes a third channel 2421 and a fourth channel 2422. The third channel 2421 communicates with the intake channel 111 and extends along the second direction. The fourth channel 2422 is arranged in a ring around the vacuum passage 251. The fourth channel 2422 connects the third channel 2421 and the second channel 243.

[0063] It is conceivable that in other embodiments, the arrangement of the air intake channel 111 and the first channel 242 is not limited, as long as the arrangement can ensure normal airflow.

[0064] In some embodiments, see further reference. Figure 8 The outer portion 26 has a stepped surface 261 at one end near the pickup portion 21 along the first direction, and the air outlet 241 of the air outlet channel 24 is located on the stepped surface 261. This arrangement makes the path of the air outlet channel 24 longer, resulting in better heat exchange. At the same time, the airflow flows out of the air outlet channel 24 through the air outlet 241 on the stepped surface 261 and enters the receiving cavity 13. After exchanging heat with the pressure head 20 in the receiving cavity 13, it flows out through the first exhaust hole 124, further ensuring the heat exchange effect.

[0065] It should be noted that when the second channel 243 includes multiple sub-channels 2431, each sub-channel 2431 has a sub-hole, and all the sub-holes together form the air outlet 241 of the air outlet channel 24.

[0066] In other embodiments, the peripheral portion 26 has an outer peripheral surface surrounding the axis, and the air outlet 241 of the air outlet channel 24 is located on the outer peripheral surface of the peripheral portion 26. In this way, the airflow can flow smoothly through the air outlet 241 to the first exhaust port 124 for discharge, ensuring the exhaust effect.

[0067] It should be noted that, regardless of whether the air outlet 241 is located on the stepped surface 261 or on the outer peripheral surface of the outer part 26, the air outlet 241 is positioned close to the first exhaust hole 124 so that the airflow can be discharged through the first exhaust hole 124 in a timely manner after flowing out through the air outlet 241.

[0068] In some embodiments, see further reference. Figure 4 and Figure 8 The pressure head 20 also includes an overlapping portion 27, which is connected to the air outlet 23 and located within the receiving cavity 13. The overlapping portion 27 overlaps and fits against the cavity wall of the receiving cavity 13 and surrounds the periphery of the through hole 129. By providing the overlapping portion 27, the assembly stability of the pressure head 20 and the connecting structure 10 can be increased.

[0069] For details, please refer to [link / reference]. Figure 4 The receiving cavity 13 includes a first cavity 131 located between the stepped surface 261 and the overlapping part 27. The first exhaust hole 124 is directly opposite the first cavity 131 along the second direction. After the gas discharged through the exhaust hole 241 provided on the stepped surface 261 enters the first cavity 131, it flows directly to the first exhaust hole 124 and is discharged.

[0070] Continue reading Figure 4 When the air outlet 23 is not tightly fitted to the inner wall of the cover 12, the cover 12 is provided with a blocking part 127. The blocking part 127 can block the airflow in the first cavity 131 from flowing to the gap between the air outlet 23 and the cover 12, ensuring that the airflow flows from the first cavity 131 to the first exhaust hole 124 for discharge.

[0071] Furthermore, in order to ensure a better assembly effect between the pressure head 20 and the connecting structure 10, the size of the connecting part 22 is set to be larger than the size of the air outlet 23. At this time, a step is formed between the connecting part 22 and the air outlet 23, and the connecting part 22 overlaps the upper limit pressure head 20 of the cover 12.

[0072] In some embodiments, see further reference. Figure 5 The second end face 122 is provided with a second exhaust port 128, which is connected to both the exhaust channel 24 and the first exhaust port 124. Thus, when the crimping device 100 crimps the electronic component 400 onto the test holder 200 for testing, a portion of the airflow flowing out through the exhaust channel 24 is discharged through the second exhaust port 128 to directly exchange heat with the electronic component 400, ensuring effective temperature control of the electronic component 400.

[0073] Optionally, the first end face 121 is provided with a plurality of second exhaust holes 128, which are arranged sequentially and at intervals around the through hole 129. In this arrangement, airflow is discharged from the plurality of second exhaust holes 128, ensuring uniform temperature throughout the electronic component 400.

[0074] Another embodiment of this application provides a test sorting machine, including a feeding device, a conveying device, a test seat 200, a receiving device, and the aforementioned pressing device 100.

[0075] The feeding device provides electronic components 400 to the conveying device, which then transports the electronic components 400 between the feeding device and the crimping device 100. The crimping device 100 picks up the electronic components 400 transported by the conveying device and crimps them onto the test holder 200 for testing. The conveying device can also transport the tested electronic components 400 to the receiving device for collection. Since the crimping device 100 has beneficial effects, the test sorting machine including the crimping device 100 has the same beneficial effects, which will not be described in detail here.

[0076] Specifically, the test holder 200 has a test cavity. When the pressure head 20 presses the electronic component 400 onto the test holder 200, the second part 126 of the cover 12 is accommodated in the test cavity. At this time, the airflow discharged through the first exhaust port 124 and the second exhaust port 128 enters the test cavity, reducing the temperature difference between the surrounding environment and the pressure head 20, thus facilitating temperature control of the electronic component 400. An exhaust gap 300 is formed between the connecting structure 10 and the test holder 200, allowing the airflow in the test cavity to flow out through the exhaust gap 300, ensuring a continuous flow of airflow through the first exhaust port 124 and the second exhaust port 128, thereby guaranteeing effective temperature control of the electronic component 400.
