Description of the Invention: [Technical Field] The present invention relates to an open device for measuring a splaying machine, especially for an open plate loading and unloading (desorption, 4+ u ^ p 〇n ) The technical test sorter uses an open device. [Prior Art] For testing of electronic components (especially semiconductor components), it is necessary to use a tester that tests electronic components of electrical connections and a test handler that electrically connects electronic components to the tester. In order to increase the processing capacity, the test sorter uses a carrier for transporting a plurality of semiconductor elements in a state of being loaded in a row (in (1) as a board). The carrier is provided with a plurality of insertion portions arranged in a matrix, and the semiconductor element is mounted on the carrier in a state of being inserted into the insertion portion. Usually, a semiconductor element tested using a test sorter is provided in a state of being loaded on a user tray. The semiconductor element supplied in the state of being loaded on the user tray is moved to the carrier by a pick and place apparatus, and the semiconductor element on the carrier which has been tested is moved to the user tray by another pick-and-place device. Further, when the carrier on which the semiconductor element is mounted is moved along the predetermined loop path to reach the test site, the semiconductor element is electrically connected to the test socket of the tester in a state of being loaded on the carrier. As described above, the carrier is moved along the loop path 201118380 in the state in which the semiconductor element is mounted, and in particular, in the side docking type test sorter, the section in which the carrier is vertically erected is moved. Therefore, the insertion portion of the carrier plate needs to be provided with a detachment preventing means to prevent the semiconductor element from coming off. However, since the insertion portion of the carrier plate is provided with the separation preventing means, when the semiconductor element is moved from the user tray to the carrier or from the carrier to the user tray, it is necessary to release the anti-disengagement state of the separation preventing device and open the insertion portion (open carrier) Therefore, the test sorter needs to be equipped with an open device. FIG. 1 is a view schematically showing a front surface of a conventional opening device 100. Referring to Fig. 1 'the prior art opening device 100 is composed of a lifting plate 110, an opening plate 120, a bolt 130, and a cylinder 140. The lift plate 110 is provided to directly receive the driving force of the cylinder 140 and can be raised and lowered. The upper surface of the open plate 120 is provided with a plurality of open pins p to open the insertion portion of the carrier. The bolt 130 serves as a fixing means for fixing the open plate 120 to the lift plate 11A. The cylinder 140 provides the driving force required for the lifting plate 11 to be lifted and lowered. The opening device 100 as described above raises the lifting plate U and the opening plate 120 by the driving force of the air cylinder 140, and the opening pin p operates the separation preventing device to open the insertion portion of the carrier. If the lifting plate 110 and the opening plate 120 are lowered, the end is completed. The open state of the insertion portion of the carrier. In addition, the semiconductor components tested by the test sorter will change their types from time to time. At this time, the insertion portion of the carrier board needs to be replaced with an insertion portion that can correspond to the physical specifications of the semiconductor element 201118380. However, if the insertion portion is replaced, the position of the separation preventing means normally formed in the insertion portion also changes, so that the opening plate of the opening device also needs to be replaced together. However, the existing opening device 100 requires a tool (screwdriver) on the upper side of the opening device 100 to loosen or tighten the bolt 13〇 for unloading the original open plate 120 and then installing a new open plate. Because the opening device 100 is disposed deep inside the test sorter, and the other side has other 0 devices. Therefore, the operation of the existing open apparatus 100 for replacing the open panel 12 is cumbersome and wastes a lot of time. Further, in order to properly manipulate the opening pin p of the opening plate 120 to properly manipulate the insertion preventing portion, the opening plate 120 is required to form an appropriate surface contact with the carrier plate. However, if the opening plate 120 and the carrier plate are in a different horizontal state, the opening pin p is opened. Not only is it impossible to properly manipulate the detachment prevention device, and the insertion portion may be damaged. SUMMARY OF THE INVENTION An object of the present invention is to provide an open device for a test sorter that can easily replace an open plate without using a special tool.

The hanging end 212a-lb is interlocked with the operating end 212a-la when the manager rotates the operating end 2i2a ia The hook card is connected or the hook of the card end 22 lb is released. Moreover, as shown in Fig. 2d, the two corner sides of the contact surface of the hook end (1) a]b and the snap end 22ib have an inclined surface Li. For attaching the card terminal mb or unmounting by rotation, the protruding protrusion p of the card terminal 21 can be easily crossed to achieve an appropriate hooking operation or a hooking operation. A fixing pin 21 is formed between the operating end 212a_la of the rod 212a-1 and the hanging end 2l2a-lb. The through hole 2l2a-lc through which 2&_2 passes. The solid W 212a·2 is for rotatably fixing the operating rod 212a-1, and is fixed to the insertion groove 212c 10 201118380 by the through hole 212a.le of the operating rod 212 The wave-shaped gasket 212a-3 is disposed between the head portion H of the fixing pin 212a_2 and the operation cup 2 12a-1 as a member that applies a downward-direction elastic force to the operation lever. Next, the opening device 2 of the above configuration The handling and opening operation of the open panel 22 is described. Since the abnormality of the open panel 220 or the replacement of the semiconductor component to be tested 'need to replace the existing open panel 220 with a new open panel, reference is made to the plan view of FIG. The manager manually pushes the operating end 2l2a-la of the operating lever to the right side to rotate the operating lever 212a1 in the counterclockwise direction. Referring to FIG. 4, due to the operation, the lever is rotated counterclockwise according to the operating lever. The hooking ends 212a-lb release the hooking of the latching ends 221b. At this time, due to the action of the inclined surface S1 of the hooking ends 212a-lb and the wave-shaped washers 212a3, the hooking ends 212a-lb can smoothly pass through the carding ends. P1 of the 221b. σ When the vertical and horizontal forces act on the operating lever, the wave washers 212 & _3 which are maintained at a predetermined interval from the operation 且 and are only partially in contact with the operating lever are biased so that the hooking ends 212a_lb of the operating lever are horizontally fixed to the pin 2i2a_2 Tilting upward from the reference, thereby being able to pass through the projection p portion of the latching end 221b. The hooking ends 212a-lb release the hooking of the latching end 221b, and when the open panel 22 is released from the state of the mounting board 212, the manager After the existing open panel 200 is removed, as shown in FIG. 5, the snap-in protrusion 221 of the new open panel is inserted into the insertion groove 212c (specifically, a portion which is inserted into the insertion groove and further recessed downward). 11 201118380 Referring to FIG. 6', in a state where the engaging projection 221 is inserted into the insertion groove 2c, the open plate 220 is placed on the upper side of the mounting plate 212, the manager will operate the operating end 212a of the lever 212a-1. La is pushed to the left to rotate the operating lever 212a-1 in the clockwise direction. Under this operation, as shown in Fig. 7, the operating lever 212a-1 is rotated in the clockwise direction so that the hooking end is hooked to the engaging end 221b to complete the mounting of the opening plate 220. Similarly, due to the action of the inclined surface I of the hook ends 212a-lb and the wave washers 212a_3, the hook ends 212a-lb can smoothly pass through the portion of the land p of the snap end 221b. Moreover, in the state in which the wave-shaped washer 212a_3 is hooked to the latching end 221b to complete the mounting of the open plate 22, the elastic force of the downward direction is continuously applied to the hook end to achieve a locking effect, so that The hook ends 212a-lb can maintain the hooked state of the clip end 221b before being subjected to an externally applied external force. 3 to 7, only the portion of the snap-in protrusion 221 of the open plate is indicated by a comb line, and the symbol of the hook-up protrusion of the new open plate in FIGS. The symbols of the engaging projections of the conventional open plates of Figs. 3 and 4 are the same. It is known that in order to open the insertion portion of the carrier plate, the open plate 22A and the carrier plate need to be in surface contact. In this case, the horizontal state of the carrier plate and the open plate 220 may be different (or the horizontal state of the insertion portion of the carrier plate). Slightly bad). Even in such a case, the cylinder 23 is operated to raise the lift module 2 1 〇 and the open plate 220, as shown in an exaggerated view of FIG. 8, the side portion of the open plate 22 (the left portion in the drawing) is first and the carrier CB. contact. As shown in Fig. 8, in the state of 201118380, the spring 214 which is first contacted to one side of the carrier CB is compressed by the slight and continuous rise of the lifting module 210 and the opening plate 220, as shown in Fig. 9. The carrier CB and the open plate 220 form a perfect surface contact with each other. Thereby, the opening pin p of the opening plate 220 can appropriately open the insertion portion of the carrier CB.
