Description

Technical Field

[0001] This utility model relates to the field of automated production technology, and in particular to a floating insert opening device and a sorting machine. Background Technology

[0002] Semiconductor chips undergo rigorous electrical performance testing before leaving the factory. To improve testing efficiency, test trays are used. Multiple inserts for loading semiconductor chips are embedded in the test tray in rows and columns. These inserts are equipped with anti-detachment structures to restrain the semiconductor chips and prevent changes in their position relative to the test tray during transfer or testing. When a robotic arm loads or removes a semiconductor chip from an insert, an opening device is needed to open the anti-detachment structure. The opening device has an opening seat at its top. As the opening seat rises, an opening element on the opening seat can be inserted into the insertion hole of the insert to open the anti-detachment mechanism.

[0003] The testing process involves different high and low temperature environments, which inevitably causes the test tray to expand and contract due to heat and deform. This causes a positional deviation between the insertion hole and the opening seat. During the docking process, when the opening seat is inserted into the insertion hole, the test tray may jam or vibrate. This can lead to semiconductor chip leakage, spillage, breakage, alarm shutdown, resulting in significant economic losses and reduced production efficiency.

[0004] To address this, some opening devices incorporate a floating mechanism below the opening seat, allowing the opening component on the opening seat to smoothly align with the insertion hole. However, during use, the floating mechanism may deform, causing the initial position of the opening seat to change. Consequently, when facing an insertion component whose position has not changed, the opening component cannot align smoothly, which can also lead to jamming or vibration of the test tray.

[0005] Therefore, it is urgent to study a floating insert opening device and a sorting machine to solve the above problems. Utility Model Content

[0029] This utility model provides a floating insert opening device and a sorting machine. The floating insert opening device includes a floating component, a lifting component, and an opening component. The floating component includes a floating support base and an elastic element, with the elastic element disposed between the floating support base and the opening base. The floating support base is connected to the output shaft of the lifting drive component and can reciprocate along a first direction. When the lifting drive component is activated, the floating support base and the elastic element drive the opening base closer to the insertion hole. Under the action of the elastic element, the opening base can change position relative to the floating support base, thereby adapting to positional deviations between the insertion hole and the opening component in the test tray, ensuring proper opening. The opening component can be smoothly inserted into the insertion hole to open the anti-detachment structure. Simultaneously, a centering component is provided between the floating support and the opening component. This component guides the relative position between the floating support and the opening component and constrains the movement of the floating support relative to the opening component. When the opening component disengages from the insertion component, it resets the opening component relative to the floating support, ensuring that the initial position of the opening component relative to the floating support remains unchanged. This allows the opening component to smoothly align with the insertion component whose position in the insertion hole has not changed. This avoids jamming and vibration of the test tray during the alignment process, thus preventing significant economic losses and ensuring production efficiency. Attached Figure Description

[0046] The embodiments of this utility model are described in detail below.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0047] like Figures 1 to 7 As shown, this embodiment provides a floating insert opening device, which includes a base 100, an opening component 400, a lifting component 200, and a floating component 300. The opening assembly 400 includes an opening seat and an opening member 411 disposed on the opening seat for opening the anti-detachment structure in the insert; the lifting assembly 200 includes a lifting drive member 210 disposed on the base 100, and the output shaft of the lifting drive member 210 can reciprocate along its own axis to provide a driving force in a first direction; the floating assembly 300 includes a floating support 310 and an elastic member 330, the floating support 310 is connected to the output shaft and can move synchronously with the output shaft; the elastic member 330 is disposed between the floating support 310 and the opening seat to make the opening assembly 400 float relative to the floating support 310; a centering member is also disposed between the floating support 310 and the opening seat, the centering member is used to guide the relative position between the floating support 310 and the opening seat and constrain the movement of the floating support 310 relative to the opening seat, and when the opening assembly 400 disengages from the insert, the opening seat is reset relative to the floating support 310.

[0048] In this floating insert opening device, under the action of the elastic element 330, the opening seat can change position relative to the floating support 310, thereby adapting to the situation where there is a positional deviation between the insertion hole and the opening element 411 in the test tray, ensuring that the opening element 411 can be smoothly inserted into the insertion hole to open the anti-detachment structure. At the same time, since a centering component is also provided between the floating support 310 and the opening seat, the centering component is used to guide the relative position between the floating support 310 and the opening seat and constrain the movement of the floating support 310 relative to the opening seat. When the opening component 400 disengages from the insert, it resets the opening seat relative to the floating support 310, thereby ensuring that the initial position of the opening seat relative to the floating support 310 remains unchanged. When facing an insert whose insertion hole position has not changed, the opening element 411 can also be smoothly connected. This avoids the phenomenon of the test tray jamming or vibrating plate during the connection process, thereby avoiding significant economic losses and ensuring production efficiency.

[0049] Combination Figure 4 and Figure 5 As shown, the floating support 310 has a floating channel 311, and the floating assembly 300 includes a floating pin 340. The floating pin 340 is fixed to the opening seat by a fastening screw 342 and partially passes through the floating channel 311. The elastic element 330 includes a spring, which is sleeved on the outer periphery of the floating pin 340 and its two ends abut against the opening seat and the floating support 310, respectively. The top of the floating pin 340 has a fastening screw hole, and the opening seat has a fastening hole. The outer diameter of the floating pin 340 is larger than the diameter of the fastening hole. The fastening screw 342 passes through the fastening hole and is screwed into the fastening screw hole. The opening seat is clamped between the nut of the fastening screw 342 and the floating pin 340. During the upward movement of the output axis of the lifting drive component 210, the floating support seat 310 is driven to move upward. The floating support seat 310 supports the opening seat through the elastic element 330 and drives the opening seat to move upward. When the opening seat is deflected due to resistance, the elastic element 330, which is sleeved on the outer periphery of the floating pin 340, will not misalign, thus ensuring the positional stability of the elastic element 330. In other embodiments, the elastic element 330 can also be a disc spring, which can satisfy the function of compressing and storing force and releasing elastic force after restoration.

[0050] In some embodiments, at least three floating channels 311 are provided, and these at least three floating channels 311 are arranged around the outer periphery of the output shaft of the lifting drive member 210. At least three elastic elements 330 and at least three floating pins 340 are each provided, with at least three elastic elements 330 respectively sleeved around the outer periphery of the corresponding floating pin 340, and at least three floating pins 340 respectively passing through the corresponding floating channels 311. Alternatively, four floating channels 311 are provided, located at the four corners of the floating support base 310, and four elastic elements 330 and four floating pins 340 are each provided, corresponding to the four floating channels 311. When the opening seat is subjected to localized pressure, the four elastic elements 330 provide support to the opening seat with different tilt states through varying degrees of compression. The arrangement of four elastic elements 330 significantly reduces the pressure on each elastic element 330, helping to improve the service life of the elastic elements 330.

[0051] In order for the opening seat to reset relative to the floating support 310 when the opening assembly 400 disengages from the insert, in some embodiments, the centering component includes a floating lower channel 3112 formed at the end of the floating channel 311 and a stop portion 341 disposed at the end of the floating pin 340. The inner diameter of the floating lower channel 3112 gradually increases from top to bottom, and the outer diameter of the stop portion 341 gradually increases from bottom to top, and the maximum outer diameter of the stop portion 341 is greater than the minimum inner diameter of the floating lower channel 3112; the stop portion 341 can be located in the floating lower channel 3112 to allow the opening seat to reset relative to the floating support 310. Specifically, the taper of the inner sidewall of the floating lower channel 3112 is the same as the taper of the outer sidewall of the stop portion 341, and the minimum outer diameter of the stop portion 341 is smaller than the minimum inner diameter of the floating lower channel 3112. After the opening component 400 disengages from the insert, under the action of the elastic element 330, the opening seat gradually moves away from the floating support seat 310, and drives the floating pin 340 to move synchronously. During the movement of the floating pin 340, firstly, the smallest diameter part of the stop part 341 enters the floating lower channel 3112, and then the entire stop part 341 enters the floating lower channel 3112. The outer side wall of the stop part 341 and the inner side wall of the floating lower channel 3112 abut against each other, and drive the axis of the floating pin 340 to gradually coincide with the center line of the floating lower channel 3112, thereby causing the opening seat to reset relative to the floating support seat 310. The floating channel 311 includes a connected floating upper channel 3111 and a floating lower channel 3112. The inner diameter of the floating upper channel 3111 is larger than the inner diameter of the floating lower channel 3112, and the elastic element 330 sleeved on the outer periphery of the floating pin 340 is located in the floating upper channel 3111.

[0052] To ensure the effectiveness of opening and resetting the socket, combined with Figure 6 and Figure 7As shown, in some embodiments, the centering component further includes a centering seat 510 and a centering member 520. The centering seat 510 includes a centering connecting portion 511 and a centering mounting portion 512. One end of the centering connecting portion 511 is connected to the opening seat. The centering mounting portion 512 is connected to the centering connecting portion 511 and is located below the floating support seat 310. The centering member 520 is disposed on the centering mounting portion 512. One of the top of the centering member 520 and the bottom of the floating support seat 310 has a positioning protrusion 521, and the other has a positioning groove 312. The outer diameter of the positioning protrusion 521 gradually decreases in the direction toward the positioning groove 312, and the inner diameter of the positioning groove 312 gradually increases in the direction toward the positioning protrusion 521. When the opening seat moves away from the floating support seat 310, the positioning protrusion 521 can be inserted into the positioning groove 312 to reset the opening seat. The positioning protrusion 521 is hemispherical or has a chamfered end, and the groove wall of the positioning groove 312 is conical or arc-shaped. This configuration ensures that when the opening seat is away from the floating support seat 310, the positioning protrusion 521 is inserted into the positioning groove 312, and guided by the inner wall of the positioning groove 312, it can guide the opening seat to return to its original position relative to the floating support seat 310.

[0053] In one embodiment of this invention, a positioning groove 312 is provided on the side of the floating support 310 away from the opening seat, and a centering seat 510 is provided on the opening seat. An elastic element 330 is provided between the opening seat and the floating support 310 at the centering seat 510. In this embodiment, a positioning protrusion 521 is provided on the top of the centering element 520 to improve processing convenience. The elastic element 330 also helps to increase the support force of the opening seat away from the floating support 310; in addition, the elastic element 330 at this location also helps to improve the force balance of the opening seat and avoid problems such as the opening seat sinking into the floating support 310 at the centering seat 510. In this embodiment, the outer diameter of the positioning protrusion 521 and the inner diameter of the positioning groove 312 both gradually decrease from bottom to top.

[0054] Regarding the installation of the elastic element 330, a first groove 421 is provided on the side of the opening seat facing the floating support seat 310, and a second groove 313 is provided on the side of the floating support seat 310 facing the opening seat. One end of the elastic element 330 of the centering seat 510 is located in the first groove 421, and the other end is located in the second groove 313.

[0055] To limit the maximum distance between the opening seat and the floating support seat 310, in some embodiments, the centering member 520 is a stud with its top protruding upward to form a positioning protrusion 521. The centering mounting portion 512 is provided with a centering threaded hole, and the stud and the centering threaded hole are threadedly engaged to make the distance between the positioning protrusion 521 and the centering mounting portion 512 adjustable. Tightening the stud moves the positioning protrusion 521 closer to the centering mounting portion 512, that is, the positioning protrusion 521 moves away from the floating support seat 310, thereby increasing the maximum distance between the opening seat and the floating support seat 310. Tightening the stud in the opposite direction moves the positioning protrusion 521 closer to the floating support seat 310, thereby decreasing the maximum distance between the opening seat and the floating support seat 310. In addition, the compression amount of the elastic member 330 in the working state can be adjusted to control the elastic support force when the opening member 411 on the opening seat is inserted into the insertion hole. Finally, the initial position of the opening seat can also be adjusted to accommodate inserts with different distances.

[0056] In some embodiments, to lock the stud, the adjusting nut 530 is screwed onto the stud and abuts against the centering mounting portion 512, thereby locking the stud to the centering mounting portion 512. In other embodiments, to lock the stud, the lower end of the stud has a smooth, unthreaded shank, and the centering mounting portion 512 has a locking screw hole. The locking screw and the locking screw hole are threaded together and abut against the stud.

[0057] The floating insert opening device includes two centering seats 510 and two centering members 520. The two centering members 520 can be inserted into corresponding positioning grooves 312. The two centering seats 510 are respectively located on both sides of the output shaft of the lifting drive member 210 to ensure the balance of force on the opening seat. Three or more centering seats 510 can also be provided, and they are symmetrical about the output shaft of the lifting drive member 210.

[0058] In another embodiment of this example, the positioning groove 312 is provided on the top of the centering member 520, and the floating support 310 is provided with a positioning protrusion 521 on the side opposite to the opening seat, which helps to reduce the weight supported by the elastic member 330, reduce the requirements on the elastic member 330, reduce costs, and improve the floating flexibility of the opening seat.

[0059] To prevent the opening seat from moving too far towards the floating support 310, which could result in an insufficient gap between them and affect the service life of the elastic element 330, in some embodiments, the floating assembly 300 further includes a rigid limiting member 320. The rigid limiting member 320 is located on the opening seat and has a limiting portion at its lower end that abuts against the top surface of the floating support 310. The rigid limiting member 320 is a limiting screw, and the opening seat has a limiting screw hole. The limiting screw is threaded into the limiting screw hole, and its lower end face forms the limiting portion. For example, two limiting screws are respectively located on both sides of the output shaft of the lifting drive 210 and are symmetrical about the axis of the output shaft to ensure balanced force distribution when the opening seat is close to the floating support 310 and is limited, thus preventing lateral tilting.

[0060] In use, after the opening member 411 is inserted into the insertion hole, the opening seat needs to continue to move closer to the insertion member so that the opening member 411 can push and open the anti-dislodgement structure of the insertion member. During this process, it is necessary to ensure the positional stability of the opening seat and avoid wobbling relative to the floating support 310. To achieve this purpose, in some embodiments, one of the floating support 310 and the opening seat is provided with a guide protrusion 314 and the other is provided with a guide groove 422. When the floating support 310 and the opening seat are close together, the guide protrusion 314 can be inserted into the guide groove 422.

[0061] Specifically, the outer diameter of the guide protrusion 314 gradually decreases along the direction approaching the guide groove 422, while the inner diameter of the guide groove 422 gradually decreases along the direction away from the guide protrusion 314. The minimum outer diameter of the guide protrusion 314 is smaller than the maximum inner diameter of the guide groove 422. This arrangement allows the opening seat to adapt to insertion holes at different positions. Even if there is a slight offset relative to the floating support 310, after the opening member 411 is inserted into the insertion hole, as the opening seat continues to approach the floating support 310, the guide protrusion 314 and the guide groove 422 allow the opening seat to move horizontally to a fixed position relative to the floating support 310, i.e., the axis of the floating pin 340 coincides with the center line of the floating lower channel 3112. The second and third directions, which are perpendicular to the first direction, are both horizontal directions.

[0062] To minimize the impact on the number of opening components 411 that can be installed, the opening base includes a mounting plate 410 and an adapter plate 420 connected together. The opening component 411 is disposed on the mounting plate 410, and the floating pin 340 and the rigid limiting member 320 are both mounted on the adapter plate 420. The guide groove 422 is formed in the adapter plate 420. This reduces the number of openings in the mounting plate 410 and ensures that the number of opening components 411 can be installed on the mounting plate 410.

[0063] In addition, to ensure that the opening component 411 can be smoothly inserted into the insertion hole of the insert, a positioning pin 412 is also installed on the mounting plate 410. The positioning pin 412 can be inserted and engaged with the positioning hole of the insert. Specifically, each opening component 411 is provided with two positioning pins 412, and the two positioning pins 412 corresponding to the opening component 411 are located at opposite corners of the opening component 411.

[0064] To ensure the stability and smoothness of the movement of the floating support 310, and in conjunction with Figure 1 As shown, the lifting assembly 200 also includes a guide rod 220 and a sliding bearing 230. The sliding bearing 230 is fixed to the base 100, and the base 100 is provided with a sliding channel. The upper end of the guide rod 220 is connected to the floating support 310 and is slidably disposed inside the sliding bearing 230 and the sliding channel.

[0065] In some embodiments, the lifting assembly 200 further includes a limiting rod 240 and an upper limiting member 250. The base 100 is provided with a limiting channel. The limiting rod 240 is slidably disposed within the limiting channel along a first direction. The upper end of the limiting rod 240 is connected to the floating support 310, and the lower end is connected to the upper limiting member 250 located below the base 100. The outer diameter of the upper limiting member 250 is larger than the inner diameter of the limiting channel. When the floating support 310 moves to its upper limit position, the upper limiting member 250 engages with the limiting channel and abuts against the base 100.

[0066] Four limiting rods 240 are provided, and the four limiting rods 240 are respectively located on the outer periphery of the output shaft of the lifting drive member 210. In this embodiment, the upper limiting member 250 is connected to the four limiting rods 240 simultaneously. Among them, the upper limiting member 250 is provided with a buffer 251 to buffer the buffering force between the upper limiting member 250 and the base 100. The upper limiting member 250 is provided with a clearance channel, and the lifting drive member 210 is located in the clearance channel, which makes the overall structure compact and helps to reduce the space occupation.

[0067] The lifting assembly 200 also includes a lower limit member 260, which is located between the floating support 310 and the base 100. The lower end of the lower limit member 260 abuts against the top surface of the base 100, and its upper end abuts against the bottom surface of the floating support 310. When the floating support 310 moves to its lower limit position, the lower limit member 260 abuts against the base 100. The lower limit member 260 is a sleeve fitted around the outer periphery of the limiting rod 240. The sleeve's design limits the minimum distance between the floating support 310 and the base 100 by its own height; it also allows for positioning via the limiting rod 240, avoiding the need for a fixed structure and facilitating assembly. In use, the bottom of the sleeve abuts against the base 100. When the floating support 310 moves to its lower limit position, the side of the floating support 310 facing the base 100 abuts against the top of the sleeve.

[0068] This embodiment also provides a sorting machine, including the floating insert opening device of any of the above embodiments, used to open the anti-detachment structure of the insert located in the test tray before loading the test object into the test tray or unloading the test object from the test tray. The test object can be a semiconductor chip. With the above-described structure, when the sorting machine opens the anti-detachment structure of the insert, the opening seat can change position relative to the floating support seat 310 under the action of the elastic element 330. This adapts to positional deviations between the insertion hole and the opening element 411 in the test tray, ensuring that the opening element 411 can be smoothly inserted into the insertion hole to open the anti-detachment structure. Simultaneously, a centering component is provided between the floating support seat 310 and the opening seat. This component guides the relative position between the floating support seat 310 and the opening seat and constrains the movement of the floating support seat 310 relative to the opening seat. When the opening component 400 disengages from the insert, it resets the opening seat relative to the floating support seat 310, ensuring that the initial position of the opening seat relative to the floating support seat 310 remains unchanged. Even when facing an insert with an unchanged insertion hole position, the opening element 411 can smoothly dock. This avoids jamming or vibration of the test tray during docking, thus preventing significant economic losses and ensuring production efficiency.

[0069] In addition, the sorting machine also includes a feeding device for loading the test subject into the test tray, a testing device for testing the test subject in the test tray, an unloading device for unloading the test subject in the test tray after the test is completed, and a transport device for moving the test tray and allowing the test tray to circulate between the devices.

[0070] Along the flow direction of the test tray, the floating insert opening device can be set in front of the feeding device or in front of the unloading device.

[0071] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
