In order to realize the transfer of the tray, a silo needs to be set in the production equipment. The main function of the silo is to realize the loading and unloading of the tray and the storage of the empty tray. Specifically, the silo includes a shell, a locking assembly and a lifting assembly. The shell includes a frame and a door. The frame has a cavity for accommodating the tray. A side door is opened on one side of the frame. The door is rotated at the side door. The locking assembly is used to lock the frame and the door to open or close the cavity. The lifting assembly is installed at the bottom of the cavity to support the tray in the cavity or release the tray. Open the locking assembly to open the door, put the empty tray into the silo, and then lock the door to close the door. Under the action of the lifting assembly, the tray gradually rises, and the rear top assembly set behind the door limits the position of the tray to ensure the accuracy of the tray position. If the door is not completely closed, that is, the position of the door is incorrect, the position of the rear top assembly will also be offset, resulting in inaccurate positioning of the tray. The tray must be placed accurately to realize the loading and unloading function. When the door is not in the correct position, the loading and unloading function cannot operate normally.
[0003] In the prior art, the locking assembly is mainly composed of a latch and an in-position sensor. The latch is installed on the warehouse door through a latch fixing seat. The two side plates of the frame respectively fix the latch seats. The two ends of the latch are respectively fixed to the latch seats to achieve locking of the warehouse door. One end of the latch has a micro end, and the latch seat corresponding to the micro end has an opening. The latch is pulled toward the micro end of the latch and away from the frame. The two ends of the latch are separated from the latch seat to engage the locking assembly. The micro end of the latch has a spring. When the latch is not completely inserted into the round hole of the latch seat, the latch is pressed against the latch seat under the action of the spring. At this time, the door lock is not locked and the warehouse door can be closed, but the position of the warehouse door is incorrect. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0026] In the semiconductor production process, semiconductor products are usually placed in trays to be transferred and processed between various stations. When waiting for processing or testing, the trays are placed in the silo. A lifting assembly is set at the bottom of the silo. The lifting assembly can be used to remove the trays in the silo during the rising and falling process. A rear lift assembly is set behind the silo door to limit the position of the tray. When the silo door is not closed in place, the tray placement position is prone to misalignment, which affects the lifting assembly to remove the tray.
[0027] The present application embodiment provides a silo 100, such as Figure 1 and Figure 2 As shown, it includes a frame 110 and a warehouse door 120, and the warehouse door 120 is used to block the opening of the frame 110. The frame is provided with a first buckle 111 extending toward the warehouse door, and the warehouse door 120 is provided with a second buckle 121 corresponding to the first buckle 111. The second buckle 121 is rotatably connected to the warehouse door 120, and the second buckle 121 is engaged with the first buckle 111 so that the frame 110 and the warehouse door 120 are locked. A stopper 112 is also provided on the frame 110, and the extension direction of the stopper 112 is the same as the extension direction of the first buckle 111. The stopper 112 is used to limit the continued movement of the warehouse door 120 toward the frame 110.
[0028] The silo 100 of the embodiment of the present application is applied to semiconductor production equipment and is used to place material trays. Specifically, the silo 100 includes a frame 110 and a silo door 120. The frame 110 has an inlet and outlet for feeding material trays. The silo door 120 is arranged at the inlet and outlet and can block the inlet and outlet after the material tray is placed. The inlet and outlet is the opening of the frame 110. Specifically, the silo door 120 and the frame 110 are movably connected. When the silo door 120 moves relative to the frame 110 to expose the opening, the material tray can enter the silo 100 through the opening. After the material tray enters the silo 100, the silo door 120 blocks the opening and the rear top assembly behind the silo door 120 pushes the material tray, so that the material tray is at a preset position, which is convenient for the top assembly to top up.
[0029] In the embodiment of the present application, a first buckle 111 extending toward the door 120 is provided on the frame 110, and the door 120 is provided with a second buckle 121 corresponding to the first buckle 111. The second buckle 121 is rotatably connected to the door 120. When the door 120 needs to be closed, the door 120 is first moved so that the second buckle 121 is close to the first buckle 111. When the second buckle 121 contacts the first buckle 111, the second buckle 121 is rotated so that the second buckle 121 is engaged with the first buckle 111. Since the first buckle 111 is arranged on the frame 110 and the second buckle 121 is arranged on the bin door 120, when the first buckle 111 and the second buckle 121 are engaged, the movement of the bin door 120 away from the frame 110 is restricted. In addition, a stopper 112 is also arranged on the frame 110 of the embodiment of the present application. The extension direction of the stopper 112 is the same as the extension direction of the first buckle 111, and is used to restrict the bin door 120 from continuing to move toward the frame 110. Under the engagement of the first buckle 111 and the second buckle 121 and the two-way restriction of the stopper 112, the position of the bin door 120 is more accurate. Therefore, the silo 100 of the embodiment of the present application can improve the position accuracy of the bin door 120 when it is closed.
[0030] When the position accuracy of the bin door 120 when closed is high, the position accuracy of the rear top assembly behind the bin door 120 is also high, thereby being able to improve the position accuracy of the material tray in the silo 100 .
[0031] When the door 120 needs to be opened, the second buckle 121 can be rotated first to release the engagement between the second buckle 121 and the first buckle 111 , and then the door 120 can be moved to expose the opening.
[0032] The specific structure and fastening method of the first buckle 111 and the second buckle 121 are not limited in the present embodiment of the present invention. For example, it can be as follows: Figure 1 and Figure 3The hooks shown are two hooks that are relatively hooked; it can also be a groove and an elastic protrusion that are relatively hooked, or other hooking methods, etc., which can be set by those skilled in the art according to actual conditions.
[0033] When the first buckle 111 and the second buckle 121 are connected by hooking, the first buckle 111 has a first hook on the side facing the door 120, and the second buckle 121 has a second hook on the side facing the frame 110; if the second buckle 121 is rotated, the first hook and the second hook can be engaged with each other, thereby achieving the locking of the frame 110 and the door 120.
[0034] Specifically, the stop member 112 is used to limit the door 120 from continuing to move toward the frame 110, that is, to limit the critical position when the door 120 is locked with the frame 110. The specific structure of the stop member 112 is not limited in the embodiment of the present application, as long as it can limit the critical position of the door 120 relative to the frame 110.
[0035] In addition, the connection method between the door 120 and the frame 110 is not specifically limited in the present embodiment, and can be as follows: Figure 2 The rotational connection shown may also be a slide rail connection or other forms of connection, and those skilled in the art may make specific arrangements based on actual conditions.
[0036] The silo 100 provided in the present application includes a frame 110 and a silo door 120. The silo door 120 is used to block the opening of the frame 110. The frame 110 is provided with a first buckle 111 extending toward the silo door 120. The silo door 120 is provided with a second buckle 121 corresponding to the first buckle 111. The second buckle 121 is rotatably connected to the silo door 120. The second buckle 121 is engaged with the first buckle 111 to achieve the locking of the frame 110 and the silo door 120. After the frame 110 and the warehouse door 120 are locked, since the first buckle 111 is set on the frame 110 and the second buckle 121 is set on the warehouse door 120, when the first buckle 111 and the second buckle 121 are engaged, the second buckle 121 cannot move in the direction away from the first buckle 111, thereby limiting the movement of the warehouse door 120 away from the frame 110. In addition, a stopper 112 is also provided on the frame 110. The extension direction of the stopper 112 is the same as the extension direction of the first buckle 111, which is used to limit the warehouse door 120 from continuing to move toward the frame 110. Under the engagement of the first buckle 111 and the second buckle 121 and the two-way restriction of the stopper 112, the position of the warehouse door 120 is more accurate. Therefore, the silo 100 of the embodiment of the present application can improve the position accuracy of the warehouse door 120 when it is closed.
[0037] In one possible implementation of the present application, Figure 1 and Figure 3As shown, a contact sensor 113 is also provided on the frame 110, and the contact sensor 113 is flush with the end surface of the stopper 112 facing the door; if the door 120 is closed, the contact sensor 113 contacts the door 120 and can send a signal that the door 120 is closed.
[0038] In the prior art, the sensor is a distance detector, and there is a large distance between the warehouse door 120 and the detector. When the distance detector detects that the distance is a preset distance, it is determined that the warehouse door 120 is closed. When the relative position offset between the warehouse door 120 and the frame 110 is very small, the distance detector cannot detect it, which affects the detection accuracy. In the embodiment of the present application, the contact sensor 113 is arranged on the frame 110, and the contact sensor 113 is flush with the end surface of the stopper 112 facing the warehouse door. When the warehouse door 120 is closed, the warehouse door 120 contacts the stopper 112. Since the contact sensor 113 is flush with the end surface of the stopper 112, the warehouse door 120 contacts the stopper 112 while contacting the contact sensor 113. When the contact sensor 113 contacts the warehouse door 120, a closing signal of the warehouse door 120 is issued. Since the contact sensor 113 sends a closing signal of the warehouse door 120 only when the warehouse door 120 contacts the contact sensor 113, and when the warehouse door 120 contacts the contact sensor 113, that is, when the warehouse door 120 contacts the stopper 112, that is, when the warehouse door 120 is closed, the contact sensor 113 of the embodiment of the present application can improve the accuracy of detection.
[0039] Optionally, the stopper 112 is a stop screw or a stop spring.
[0040] in, Figure 1 and Figure 3 The stopper 112 is a stop screw, which is threadedly connected to the frame 110. The stop screw is rigid, and the distance between the end of the stop screw and the frame 110 is adjusted to determine the stop position of the door 120. In order to increase the stability of the stop screw in defining the position of the door 120, a nut can be provided at the end of the screw to increase the contact area between the stop screw and the door 120.
[0041] In addition, the stopper 112 may also be a stopper spring, which is compressed when the door 120 is closed, and accumulates elastic potential energy. When the first buckle 111 and the second buckle 121 are released from engagement, the stopper spring releases the elastic potential energy, and drives the door 120 to separate from the frame 110. It is understandable that, because the stopper spring is a retractable component, in order to limit the critical position of the door 120 relative to the frame 110, the position of the end of the stopper spring when it is compressed to the shortest distance can be set as the critical position of the door 120.
[0042] In one achievable method of the embodiment of the present application, first buckles 111 extending toward the door 120 are respectively provided at both ends of the frame 110 along the first direction, and second buckles 121 are respectively provided at both ends of the door 120 along the first direction. The two first buckles 111 and the two second buckles 121 are respectively engaged with each other in a one-to-one manner so that the frame 110 is locked with the door 120.
[0043] A first buckle 111 is respectively provided at both ends of the frame 110, and a second buckle 121 is respectively provided at both ends of the door 120. In this way, when the door 120 blocks the opening of the frame 110, the opposite ends of the door 120 are locked by buckles, which can further improve the position accuracy of the door 120 when it is closed.
[0044] Optional, such as Figure 2 As shown, the two second buckles 121 are fixedly connected via a rotating shaft 122 , and a rotating fixed block 123 rotatably connected to the rotating shaft 122 is provided on the door 120 , and the rotating fixed block is used to carry the rotating shaft 122 .
[0045] In practical applications, the two second buckles 121 can rotate simultaneously to achieve engagement with the first buckle 111. In the embodiment of the present application, a rotating shaft 122 is provided to connect the two second buckles 121, and a rotating fixed block 123 is provided on the door 120 to carry the rotating shaft 122. The rotating shaft 122 is rotatably connected to the rotating fixed block 123. In this way, when the rotating shaft 122 is rotated, the two second buckles 121 on the rotating shaft 122 rotate synchronously with the rotating shaft 122, and the rotating shaft 122 is located at the front of the door 120, which can facilitate the operation of the operator.
[0046] The number of the rotating fixed blocks 123 is not limited in the present embodiment of the present application, and can be as follows: Figure 2 The two shown may also be one or three, as long as they can support the rotating shaft 122 .
[0047] In order to further facilitate the operation, a handle 125 may be connected to the rotating shaft 122, and the second buckle 121 may be rotated by rotating the handle 125. In actual operation, the operator may lift or press the handle 125 to rotate the rotating shaft 122, and then the rotation of the second buckle 121 is driven by the rotation of the rotating shaft 122.
[0048] In one possible implementation of the embodiment of the present application, Figure 1 and Figure 3 As shown, the rotating fixed block 123 extends toward the second buckle 121 to form an abutment portion, and an elastic member 124 is arranged between the abutment portion and the second buckle 121. When the second buckle is subjected to force, the elastic member accumulates elastic potential energy, and when the elastic member releases the potential energy, the first buckle and the second buckle are engaged.
[0049] An elastic member 124 is arranged between the abutment of the rotating fixed block 123 and the second buckle 121. The elastic member 124 accumulates elastic potential energy when the second buckle 121 is forced to move away from the first buckle 111, so that the second buckle 121 has a tendency to move toward the first buckle 111 under the action of the elastic potential energy. In this way, when the first buckle 111 and the second buckle 121 are engaged, the engagement stability of the second buckle 121 and the first buckle is higher under the action of the elastic potential energy, and when the elastic member completes releasing the potential energy, the first buckle and the second buckle are just engaged, thereby improving the stability of the door 120 when it is closed.
[0050] Optional, such as Figure 1 and Figure 3 As shown, the first buckle 111 is disposed on the frame 110 through a limiting fixing block 114 , and the position of the first buckle 111 relative to the limiting fixing block 114 is adjustable.
[0051] Specifically, a waist-shaped hole can be provided on the first buckle 111, a connecting hole can be provided on the position-limiting fixing block 114, and then a connecting piece can be sequentially passed through the waist-shaped hole and the connecting hole to realize the connection between the first buckle 111 and the position-limiting fixing block 114. The position of the first buckle 111 and the position-limiting fixing block 114 can be adjusted by adjusting the specific position of the connecting piece in the waist-shaped hole.
[0052] The position of the first buckle 111 relative to the limiting fixing block 114 is adjustable, so that the end position of the first buckle 111 toward the door 120 can be adjusted according to actual needs, that is, the position of the first buckle 111 can be adjusted according to the engagement position of the door 120 and the second buckle 121, so that the first buckle 111 and the second buckle 121 are stably engaged.
[0053] In addition, if Figure 1 and Figure 3 As shown, the stopper 112 may also be disposed on the limiting fixing block 114 . When the stopper 112 is a stop screw, the stop screw is threadedly connected to the limiting fixing block 114 .
[0054] In one achievable manner of the embodiment of the present application, the limiting fixing block 114 is detachably connected to the frame 110 so that the position of the limiting fixing block 114 relative to the frame 110 is adjustable.
[0055] The positions of the limiting fixing block 114 and the frame 110 along the height direction can be adjusted, so that the limiting fixing blocks 114 on both sides can have the same height, which facilitates the engagement of the first buckle 111 and the second buckle 121 .
[0056] The specific adjustable method is not limited in the embodiments of the present application. For example, the connection method of the first buckle 111 and the limiting fixing block 114 can be the same as that of a waist-shaped hole. Alternatively, a mounting groove can be set on the frame 110, and the position of the limiting fixing block 114 in the mounting groove can be adjusted and then fixed. Those skilled in the art can make specific settings based on actual conditions.
[0057] The embodiment of the present application also discloses a testing mechanism with the silo, including a frame, on which a transport assembly for transporting a tray, a test assembly for testing the chips in the tray, and the silo 100 for placing the tray are arranged, and the silo 100 is located below the transport assembly. The testing mechanism with the silo includes the same structure and beneficial effects as the silo 100 in the aforementioned embodiment. The structure and beneficial effects of the silo 100 have been described in detail in the aforementioned embodiment, and will not be repeated here.
[0058] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
