[0043] As Figures 1 to 8 As shown in the utility model provides a kind of quick release type insert opening device, the quick release type insert opening device includes base 100, jacking assembly 200, opening assembly 300 and quick release assembly 400, wherein jacking assembly 200 includes jacking drive 210 and jacking plate 220, jacking drive 210 is located at base 100, and its output shaft extends along vertical direction, and can reciprocate along the axis direction of itself, jacking plate 220 is connected with output shaft, and moves synchronously with output shaft;Opening assembly 300 includes mounting plate 310 and opening piece 320 for opening the anti-drop structure of insert on mounting plate 310, mounting plate 310 is placed on jacking plate 220;Quick release assembly 400 includes rotating piece 410 and locking piece 420, among jacking plate 220 and mounting plate 310, one is equipped with lock connection channel 221, and the other is equipped with installation channel;Lock connection channel 221 includes main channel 2211 and auxiliary channel 2212 connected on the side of main channel 2211;Rotating piece 410 is located in installation channel and can rotate around its axis, locking piece 420 is located at one end of rotating piece 410, and can rotate synchronously with rotating piece 410, rotating piece 410 can pass through auxiliary channel 2212, and can be rotated to local rotating piece 410 is located on the side of auxiliary channel 2212, so that jacking plate 220 is clamped between locking piece 420 and mounting plate 310 or mounting plate 310 is clamped between locking piece 420 and jacking plate 220;When rotating piece 410 is rotated to locking piece 420 is opposite auxiliary channel 2212, locking piece 420 can pass through auxiliary channel 2212 to release the clamping of mounting plate 310 or jacking plate 220.

[0044] With the above structure, in the disassembly process of the opening assembly 300, only the rotating piece 410 needs to be screwed, so that the locking and unlocking of the mounting plate 310 and the jacking plate 220 can be achieved, the operation is convenient, and the disassembly efficiency of the opening assembly 300 is greatly improved; in addition, the disassembly process does not involve screws, avoiding the risk of electrical short circuit; the operation of screwing the rotating piece 410 is not limited by the operation space, which is convenient for operation and improves the user experience.

[0045] Regarding the specific installation position of the quick disassembly assembly 400, in some embodiments, the locking channel 221 is arranged on the jacking plate 220, the mounting channel is arranged on the mounting plate 310, in the axial direction of the rotating piece 410, the main channel 2211 and the mounting channel are opposite, and the rotating piece 410 can rotate in the main channel 2211, the locking piece 420 includes a connecting portion 421 and a locking portion 422 arranged on one side of the connecting portion 421, the locking piece 420 is connected with the rotating piece 410 through the connecting portion 421, and the locking portion 422 can pass through the auxiliary channel 2212 and can rotate to the side of the auxiliary channel 2212. Since in use, the mounting plate 310 is located on the side of the jacking plate 220 away from the jacking drive 210, therefore, the rotating piece 410 is installed on the mounting plate 310, which is helpful for the operation of the rotating piece 410; at the same time, the side of the jacking plate 220 away from the mounting plate 310 has a larger installation space for the swinging of the locking portion 422; avoiding interference between the locking portion 422 which plays a stopping role and the opening piece 320 on the mounting plate 310 during the swinging process. Of course, in the embodiment where the opening piece 320 is arranged sparsely, the rotating piece 410 can be arranged on the jacking plate 220, and the locking portion 422 can swing on the upper side of the mounting plate 310, so that the quick disassembly assembly 400 and the opening assembly 300 are arranged separately, and the opening assembly 300 does not need to be replaced together with the quick disassembly assembly 400 when it is replaced, thereby reducing the cost.

[0046] In some embodiments, the jacking plate 220 is provided with a locking groove 222, the locking groove 222 is in communication with the locking channel 221, and the locking portion 422 can rotate into the locking groove 222 and abut against the side wall of the side of the locking groove 222 facing the mounting plate 310. The locking groove 222 is arranged to reduce the solid structure of the jacking plate 220, reduce the material, and reduce the cost; on the other hand, it also helps to reduce the probability of interference between the locking portion 422 and other structures. The side wall of the locking groove 222 away from the locking channel 221 serves as a limiting wall, which can abut against the locking portion 422 and limit the continuous rotation of the locking portion 422.

[0047] In combination with the drawings Figure 5As shown, to realize the installation of the rotating member 410, in some embodiments, a part of the inner side wall of the installation channel extends inward to form a limiting convex ring 311. The rotating member 410 includes a rotating body 411 and a rotating stop 412 arranged at one end of the rotating body 411. The locking member 420 is arranged at the other end of the rotating body 411. The rotating body 411 is arranged to rotate in the limiting convex ring 311. The rotating stop 412 and the locking member 420 are arranged on the two sides of the limiting convex ring 311 respectively. The outer diameters of the rotating stop 412 and the locking member 420 are both greater than the inner diameter of the limiting convex ring 311. The above arrangement makes the rotating member 410 be stopped by the limiting convex ring 311, so as to prevent the rotating member 410 from being separated from the installation plate 310 in the direction towards the jacking plate 220.

[0048] The quick release assembly 400 further includes an elastic member 430 arranged between the rotating member 410 and the installation plate 310. The elastic member 430 is used to apply an elastic force to the rotating member 410, so as to move the rotating member 410 in the direction close to the jacking plate 220, thereby making the locking member 420 and the installation plate 310 always have a gap therebetween for accommodating the jacking plate 220 and clamping the jacking plate 220 between the locking member 420 and the installation plate 310. Specifically, the elastic member 430 includes a spring which is sleeved on the rotating body 411 and abuts against the bottom surface of the limiting convex ring 311 and the top surface of the locking member 420 at two ends respectively. The spring is sleeved on the rotating body 411 and is limited at one end by the limiting convex ring 311 and at the other end by the locking member 420, thereby realizing the omnibearing limitation of the spring and ensuring the stability of the working process of the spring.

[0049] In other embodiments, the elastic member 430 can also be replaced by a sleeve. When the length of the sleeve is limited, it is only required that the distance between the locking member 420 and the side wall of the installation plate 310 towards the jacking plate 220 is greater than or equal to the thickness of the jacking plate 220.

[0050] As to the connection between the locking member 420 and the rotating member 410, in some embodiments, the locking member 420 is detachably connected to the lower end of the rotating member 410 and located below the bottom surface of the mounting plate 310. Specifically, the rotating member 410 includes a rotating body 411 and a necked portion 413 arranged at the lower end of the rotating body 411, the lower end of the necked portion 413 is upwardly provided with a locking screw hole extending along the extending direction of the necked portion 413, the locking member 420 is provided with a locking hole, the necked portion 413 is arranged in the locking hole, a locking screw 440 is screwed into the locking screw hole, and the diameter of the locking hole is smaller than the outer diameter of the rotating body 411 and the outer diameter of the nut of the locking screw 440. The lower end of the necked portion 413 is the end of the necked portion 413 away from the rotating body 411, in other words, the lower end of the necked portion 413 is the end of the necked portion 413 close to the jacking plate 220. This arrangement can effectively connect the locking member 420 and the rotating member 410, and the nut of the locking screw 440 supports the locking member 420 to avoid the separation of the locking member 420 and the rotating member 410. Further, the quick release assembly 400 further includes a gasket 450, the gasket 450 is sleeved on the locking screw 440 and clamped between the locking member 420 and the nut of the locking screw 440. The gasket 450 is an elastic gasket 450, so that the locking screw 440 is subjected to an elastic force away from the rotating body 411 to make the connection between the locking screw 440 and the rotating member 410 more firm.

[0051] In some embodiments, the locking screw 440 can be replaced by a nut, a thread is arranged on the outer periphery of the necked portion 413, the necked portion 413 is arranged in the locking hole, and the nut is screwed on the necked portion 413 so that the locking member 420 is clamped between the stepped surface between the rotating body 411 and the necked portion 413 and the nut.

[0052] To rotate the rotating member 410, in some embodiments, the top of the rotating member 410 is provided with a rotating portion 414 for cooperating with a screwdriver to rotate the rotating member 410. The top end of the rotating member 410 is the end of the rotating member 410 away from the jacking plate 220. For example, the top end of the rotating member 410 is provided with a groove to form the rotating portion 414, the groove is in the shape of a straight line to adapt to a straight-line screwdriver. For another example, the top end of the rotating member 410 is provided with a groove to form the rotating portion 414, the groove is in the shape of a cross to adapt to a cross screwdriver.

[0053] During the rotation of the rotating member 410, to ensure that the locking member 420 can move synchronously with the rotating member 410, in some embodiments, the outer side of the necked portion 413 is provided with at least one first limiting plane, the side wall of the locking hole is provided with at least one second limiting plane, and the first limiting plane and the second limiting plane correspondingly abut. In other embodiments, the rotating member 410 and the locking member 420 can also be fixedly connected by welding or adhesion.

[0054] To ensure that the jacking plate 220 and the mounting plate 310 cannot rotate relative to each other, in some embodiments, one of the jacking plate 220 and the mounting plate 310 is provided with a positioning pin 312, and the other is provided with a positioning slot, and the positioning pin 312 can be inserted into the positioning slot. For example, the mounting plate 310 is provided with at least two positioning pins 312, the two positioning pins 312 are arranged at intervals, and are arranged on both sides of the mounting channel, and the mounting plate 310 is provided with at least two positioning slots, and the two positioning slots are arranged corresponding to the two positioning pins 312. During installation, first, the two positioning pins 312 are inserted into the two positioning slots, and then the rotating member 410 is screwed to drive the locking member 420 to rotate to one side of the auxiliary channel 2212, so that the jacking plate 220 is clamped between the locking member 420 and the mounting plate 310 to complete the installation of the opening assembly 300.

[0055] In some embodiments, the opening assembly 300 further comprises an opening positioning member 330 mounted on the mounting plate 310, which is used in cooperation with the opening member 320 to open the anti-disengagement structure of the insert. The opening positioning member 330 is a columnar structure, and the end away from the mounting plate 310 is a sharp corner structure. The insert is provided with a positioning hole, and before the opening member 320 opens the anti-disengagement structure, the opening positioning member 330 is inserted into the positioning hole, so that the opening member 320 can precisely cooperate with the anti-disengagement structure and open it.

[0056] The embodiment also provides a handler comprising the quick-release insert opening device as in any of the above embodiments, which is used to open the anti-disengagement structure of the insert in the test tray before the DUT is loaded into the test tray. The DUT can be a semiconductor chip. With the above structure, during the process of sorting and replacing different types of opening assemblies 300, the handler only needs to screw the rotating member 410 to achieve the locking and unlocking of the mounting plate 310 and the jacking plate 220, without involving screws, avoiding the risk of electrical short circuit. The operation of screwing the rotating member 410 is not limited by the operation space, which is convenient for operation and improves the user's experience.
