Description

Technical Field

[0001] The invention relates to the technical field of semiconductor testing equipment, and in particular to a mechanical anti-dropping device. Background Art

[0002] When using semiconductor testing equipment to test chips, it is necessary to use signals to identify whether there is signal feedback from the load board or performance board. If so, the motion device is prohibited from unlocking to prevent the above-mentioned components from falling off the test equipment or the chip from falling off the carrier board after unlocking. However, certain abnormal situations are inevitable in the production process. For example, the motion device of the load board or performance board is automatically unlocked due to accidental power failure of the test equipment or other signal feedback abnormalities. At this time, the carrier board will detach from the test equipment, and the chip to be tested placed therein will fall, causing damage to the appearance or function. Summary of the invention

[0003] The present invention provides a mechanical anti-detachment device, which can be arranged between a carrier board of semiconductor testing equipment and an interface board of a test head. With the cooperation of an anti-detachment piece and a release plate, semi-automatic locking or unlocking of the carrier board and the interface board is achieved. No power control is required, and manual drive is required. The device can solve the problem of chip damage caused by automatic detachment of the carrier board when an electrically controlled motion device fails due to an accidental power outage. In addition, the entire device has a simple structure, is easy to operate, and has wide application value.

[0004] The present invention can be achieved through the following technical solutions:

[0005] A mechanical anti-slip device is provided, which is provided with a plurality of them and is arranged at intervals between a carrier board of a semiconductor test equipment and an interface board of a test head, including an anti-slip component and a release plate, both of which are connected to an elastic mechanism, the anti-slip component cooperates with an opening on the release plate, one end of the anti-slip component passes through the opening and extends toward an anti-slip notch arranged on the carrier board, and the other end is provided with a pressing surface, and the release plate is provided with an unlocking protrusion.

[0006] The pressing surface or the unlocking protrusion is manually driven to change the matching position of the anti-slipping member and the opening via the elastic mechanism, thereby locking or unlocking the anti-slipping member and the anti-slipping recess, thereby completing the locking or unlocking between the carrier board and the interface board.

[0007] Furthermore, the anti-slipping piece and the release plate are arranged vertically, the opening is arranged as a small head and a large head connected to each other, the anti-slipping piece is in the shape of a rod, and a circular protrusion is arranged on it.

[0008] Push the pressing surface horizontally to drive the elastic mechanism to release the cooperation between the large head and the annular protrusion, and at the same time drive the release plate to reset along the vertical direction, so that the small head cooperates with the non-annular protrusion position of the anti-slip part, thereby locking the anti-slip part and the anti-slip notch;

[0009] Push the unlocking protrusion vertically to drive the elastic mechanism to release the cooperation between the small head and the non-circular protrusion position of the anti-slip piece, and at the same time drive the anti-slip piece to reset in the horizontal direction, so that the large head cooperates with the circular protrusion, thereby unlocking the anti-slip piece and the anti-slip recess.

[0010] Furthermore, the release plate is arranged vertically, and the opening on the release plate is arranged in a gourd shape, with the small head on the top and the large head on the bottom.

[0011] The annular protrusion is arranged at one end close to the pressing surface, and a gap is left between the pressing surface, and the small head portion is matched with the rod-shaped position between the pressing surface and the annular protrusion.

[0012] Furthermore, the elastic mechanism includes a first spring and a second spring.

[0013] The first spring is sleeved on one end of the anti-slipping member and is always in a compressed state. One end of the first spring abuts against the housing and the other end abuts against the baffle. The baffle is sleeved on the anti-slipping member, and one side of the first spring abuts against the step surface of the annular protrusion away from the pressing surface. The baffle is also on the side of the release plate away from the pressing surface. The side of the release plate close to the pressing surface is only arranged against the inner wall of the housing.

[0014] The second spring is always in a stretched state, one end of which is connected to one end of the release plate close to the unlocking protrusion, and the other end is connected to the housing.

[0015] The housing is installed between the carrier plate and the interface plate, and is provided with a through hole for the anti-dropping member to pass through, and a notch corresponding to the pressing surface and the unlocking protrusion.

[0016] The side of the release plate close to the pressing surface is arranged close to the inner wall of the shell, and the gap is consistent with the thickness of the release plate.

[0017] Push the pressing surface horizontally, the first spring is compressed, driving the anti-slip part and the annular protrusion to move in the direction close to the anti-slip notch, releasing the cooperation between the annular protrusion and the large head. At the same time, the second spring pulls the release plate downward, so that the small head cooperates with the non-annular protrusion position, realizing the locking of the anti-slip part and the anti-slip notch, and the release plate is automatically reset at this time;

[0018] Push the unlocking protrusion vertically, driving the release plate to move upward, releasing the cooperation between the small head and the non-circular protrusion position, and the compressed first spring begins to reset, driving the anti-slip component and the circular protrusion to move away from the anti-slip recess until the large head cooperates with the circular protrusion to unlock the anti-slip component and the anti-slip recess, at which time the anti-slip component automatically resets.

[0019] Furthermore, the shell includes a Z-shaped mounting plate arranged on the connector plate, a U-shaped plate arranged in the middle position of the Z-shaped mounting plate, and the two together form a square space, a notch corresponding to the pressing surface and the unlocking protrusion is arranged on the U-shaped plate, a through hole for the anti-slip part to pass through is arranged on the Z-shaped mounting plate, and an anti-slip recess is arranged on the carrier plate at the position corresponding to the through hole.

[0020] Furthermore, the pressing surface is provided with a LOCK word, and the position of the U-shaped plate corresponding to the unlocking protrusion is provided with a RELEASE word.

[0021] The beneficial technical effects of the present invention are:

[0022] 1. The mechanical anti-dropping device of the present invention is based on the electrically controlled motion device and is added between the interface board and the carrier board of the semiconductor testing equipment. It is a secondary anti-dropping protection for the carrier board, which avoids the chip damage and other problems caused by accidental failure of the electric control. At the same time, it has an unlocking function, which will not affect the loading or removal of the chip to be tested, and has strong operability.

[0023] 2. With the help of the vertically arranged anti-slip parts and release plates, no additional tools are required. The matching position of the anti-slip parts and the opening on the release plate can be changed by manually driving the elastic mechanism, thereby realizing the locking and unlocking between the anti-slip parts and the carrier plate. The structure is simple and the operation is convenient.

[0024] 3. The small head and the large head arranged above and below the opening, as well as the matching annular protrusion and rod-shaped position, can be formed by simple processing. At the same time, the final limit of the anti-slip part and the release plate is determined by the size of the shell space, which further reduces the spatial volume of the entire device and expands the scope of application of the mechanical anti-slip device of the utility model.

[0030] The specific implementation of the present invention is described in detail below with reference to the accompanying drawings and preferred embodiments.

[0031] like Figure 1 and 2 As shown, the present invention provides a mechanical anti-slip device, which is provided with a plurality of them, which are arranged at intervals between the carrier board of the semiconductor test equipment and the interface board of the test head, including an anti-slip member 1 and a release plate 2, both of which are connected to an elastic mechanism, the anti-slip member 1 cooperates with the opening on the release plate 2, one end of which passes through the opening and extends toward the anti-slip recess arranged on the carrier board, and the other end is provided with a pressing surface 11, and the release plate 2 is provided with an unlocking protrusion 21. The pressing surface 11 or the unlocking protrusion 21 is manually driven to change the matching position of the anti-slip member 1 and the opening through the elastic mechanism, so as to achieve the locking or unlocking of the anti-slip member 1 and the anti-slip recess, thereby completing the locking or unlocking between the carrier board and the interface board. In this way, with the help of the mechanical anti-slip device composed of the anti-slip member 1, the release plate 2 and the elastic mechanism, the carrier board and the interface board can be locked or unlocked under manual auxiliary drive, so as to avoid the carrier board from falling off when the electric locking mechanism is in an abnormal state, causing damage to the product to be tested on the carrier board, etc. The whole device has a simple structure, is easy to operate, and has great value for promotion and application. The details are as follows:

[0032] We can set the anti-slip member 1 and the release plate 2 vertically, such as setting the anti-slip member 1 horizontally and the release plate 2 vertically, and the opening 22 on the release plate 2 is set to be a small head and a large head connected, such as Figure 4 As shown, the anti-dropping member 1 is in the shape of a rod, and is provided with a circular protrusion 12, as shown in FIG. Figure 3 As shown, in this way, the pressing surface 11 is pushed horizontally to make the anti-slip member 1 move in the horizontal direction, driving the elastic mechanism to act, which can release the cooperation between the large head and the annular protrusion 12, and at the same time drive the release plate 2 to reset in the vertical direction, so that the small head cooperates with the non-annular protrusion position of the anti-slip member, thereby realizing the locking of the anti-slip member 1 and the anti-slip recess;

[0033] Push the unlocking protrusion 21 vertically to move the release plate 2 in the vertical direction, driving the elastic mechanism to release the cooperation between the small head and the non-annular protrusion position of the anti-slip component 1, and at the same time drive the anti-slip component 1 to reset in the horizontal direction, so that the large head cooperates with the annular protrusion, thereby unlocking the anti-slip component 1 and the anti-slip recess.

[0034] Through the vertical setting method, the movement direction of the anti-slip component 1 and the release plate 2 can be clearly defined to avoid interference, so that they can cooperate with the setting positions of the interface board and the carrier board to better complete the locking or unlocking operation. Of course, the mechanical anti-slip device of the present invention can not only be used for semiconductor test settings, but can also be applied to other components that need to be locked.

[0035] Among them, the opening 22 is gourd-shaped, with the small head on the top and the large head on the bottom. The annular protrusion 12 is arranged at one end close to the pressing surface 11, and a gap is left between the pressing surface 11. The small head cooperates with the rod-shaped position between the pressing surface and the annular protrusion 12, so as to cooperate with the horizontal pressing movement of the anti-slip component 1 to achieve locking and the vertical movement of the release plate 2 to achieve unlocking.

[0036] The elastic mechanism includes a first spring 3 and a second spring 4, wherein the first spring 3 is sleeved on one end of the anti-slipping member 1 and is always in a compressed state, and is used to drive the horizontal movement of the anti-slipping member 1, one end of which is against the shell, and the other end is against the baffle 5, and the baffle 5 is sleeved on the anti-slipping member 1, and one side of the baffle 5 is against the step surface of the annular protrusion 12 away from the pressing surface 11, and is also on the side of the release plate 2 away from the pressing surface 11. The second spring 4 is always in a stretched state, and is used to drive the vertical movement of the release plate 2, one end of which is connected to one end of the release plate 2 close to the unlocking protrusion 21, and the other end is connected to the shell,

[0037] The housing is installed between the carrier plate and the interface plate, and is provided with a through hole for the anti-dropping member 1 to pass through, and a notch corresponding to the pressing surface 11 and the unlocking protrusion 21. The side of the release plate 2 close to the pressing surface 11 is arranged close to the inner wall of the housing, and the above-mentioned gap, i.e. the gap between the annular protrusion 12 and the pressing surface 11, is consistent with the thickness of the release plate 2.

[0038] When the pressing surface 11 is pushed horizontally, one side of the baffle plate 5 is pressed against the step surface of the annular protrusion 12 and the side surface of the release plate 2, and the other side is connected to the first spring 3. Pushing the anti-slip member 1 to drive the baffle plate 5 to move will cause the first spring 3 to be compressed, driving the anti-slip member 1 together with the annular protrusion 12 to move in the direction close to the anti-slip recess, releasing the cooperation between the annular protrusion 12 and the large head. At the same time, since the second spring 4 is always in a stretched state, it will automatically pull the release plate 2 downward, that is, automatically reset, so that the small head is matched with the rod-shaped position, and the sizes of the two are the same. Therefore, the step surface of the annular protrusion 12 in the rod-shaped position will press against the release plate 2 position around the small head. The elastic force of the first spring 3 in the compressed state will act on the release plate 2 through the annular protrusion 12, so that the release plate 2 will press against the inner wall of the shell again. At this time, the inner wall plays a role in limiting the horizontal movement of the anti-slip member 1, thereby locking the anti-slip member and the anti-slip recess;

[0039] The unlocking protrusion 21 is pushed vertically to drive the release plate 2 to move upward, and the opening moves toward the direction of the large head. The small head gradually separates from the step of the rod-shaped position, and the cooperation between the small head and the rod-shaped position is released. At this time, the compressed first spring 3 begins to reset, driving the anti-slip component together with the annular protrusion 12 to move in the direction away from the anti-slip recess, that is, automatically reset, until the large head cooperates with the annular protrusion. At this time, the baffle 5 contacts the side of the release plate 2, and the elastic force of the first spring in the compressed state will be transmitted to the release plate 2 through the baffle 5, so that the release plate 2 will rest against the inner wall of the shell again. At this time, the inner wall limits the horizontal movement of the anti-slip component, thereby realizing the unlocking of the anti-slip component 1 and the anti-slip recess.

[0040] In order to adapt to the vertical movement of the release plate 2, the shell should be designed to have a square structure, or at least the inner wall that is close to the release plate 2 should be a planar structure, and it should be arranged along the movement direction of the release plate 2 to cooperate with the movement of the release plate 2; of course, we can set guide grooves on the inner wall of the shell along the movement direction of the release plate 2, and clamp the two sides of the release plate 2 in the corresponding guide grooves, so that it can not only meet the vertical movement requirements of the release plate 2, but also play a role in limiting the horizontal direction.

[0041] In order to better define the position of the baffle plate 5 on the anti-slip component 1 , a retaining spring 6 may be provided between the baffle plate 5 and the step surface of the annular protrusion 12 so that the retaining spring 6 may directly rest against the baffle plate 5 .

[0042] like Figure 1 and 2 As shown, the shell includes a Z-shaped mounting plate 7 arranged on the connector plate, and a U-shaped plate 8 is arranged in the middle position of the Z-shaped mounting plate 7. They can be fixed together by bolts, and the two together form a square space for placing the anti-slip component 1, the release plate 2, the elastic mechanism, etc., and the size thereof is determined according to the movement range of the anti-slip component 1 and the release plate 2. A notch corresponding to the pressing surface 11 and the unlocking protrusion 21 is arranged on the U-shaped plate 8, and a through hole for the anti-slip component 1 to pass through is arranged on the Z-shaped mounting plate 7, and an anti-slip recess is arranged at the position corresponding to the through hole on the carrier plate, wherein the middle position of the Z-shaped mounting plate is convenient for cooperation with the U-shaped plate 8, and the positions at both ends can cooperate with the connector plate and the carrier plate, so it is convenient for installation and avoidance.

[0043] The word LOCK may be provided on the pressing surface 11 , and the word RELEASE may be provided on the U-shaped plate 8 at a position corresponding to the unlocking protrusion 21 , so as to remind the user of the operation direction.

[0044] The unlocking protrusion 21 is arranged perpendicular to a side surface of the release plate 2. Figure 4As shown, an extension tongue 22 is provided on each side of the side opposite to the one side, a spring pin 9 is provided across the two side plates of the U-shaped plate 8, and two second springs 4 are provided, which are vertically arranged between the extension tongue 22 and the spring pin 9, one end of which is connected to the extension tongue 22, and the other end is connected to the spring pin 9, so as to ensure that the elastic force can be applied to the release plate 2 to the maximum extent. In addition, the distance between the unlocking protrusion 21 and the upper edge of the corresponding notch on the U-shaped plate 8 should be consistent with the inner diameter of the large head, so that the movement range of the unlocking protrusion 21 can be limited.

[0045] Although specific embodiments of the present invention are described above, those skilled in the art should understand that these are merely examples and that various changes or modifications may be made to these embodiments without departing from the principles and essence of the present invention. Therefore, the scope of protection of the present invention is limited by the appended claims.
