The present invention relates to a multi-socket pusher, and more particularly, to a multi-socket pusher capable of simultaneously pushing a plurality of sockets mounted in a device programmer (ROM writer) for a handler.

Semiconductor memories, such as EEPROM or flash memory, are produced in various sizes and shapes, and their uses are also widely used.

Information communication devices such as portable terminals, GPS devices, PDAs, and set-top boxes are embedded with a predetermined semiconductor memory chip, and an enterprise producing such information communication devices must perform programming operations for semiconductor memory chips.

Typically, device programmers, such as ROM writers, are used for programming tasks for semiconductor memory chips.

Device programmers, which are mainly used in the production line, are equipped with a large number of sockets and are programmed manually by the operator. In this case, due to the relationship between the manual work by the operator for a long time, the fatigue is accumulated, resulting in a decrease in productivity, and also a high failure rate.

The device programmer assumes that the device can mount eight sockets at once, and will be described in more detail. When eight sockets (see FIG. 1) 7 are mounted on the device programmer, the operator presses the upper frame 3 of the socket 7 with one hand one by one and then lower frame of the socket 7 with the other hand. A predetermined semiconductor memory chip is inserted into the mounting space of (1). After the semiconductor memory chip is inserted, the upper frame 3 is released by the elastic force of the spring 5 by releasing the pressing on the upper frame 3. Return to original state. This operation is performed in the same way for all the sockets 7. Subsequently, programming is performed on the inserted eight semiconductor memory chips by using a device programmer. Once the programming is completed, press the edge of the upper frame 3 of the socket 7 with one hand again, remove the existing semiconductor memory chip, which is already inserted, and insert a new semiconductor memory chip. After the socket 7 is executed, programming of the new semiconductor memory chip is performed. Such work is carried out by hand of the worker throughout the working hours.

As described above, when programming a conventional semiconductor memory chip, an operator may not only use both hands, but also a physical pain may be accompanied by a long time of work, such as a finger and a shoulder, and the fatigue may be accumulated. This leads to a problem of low productivity and delay in programming.

Accordingly, a device for connecting one cylinder to one socket 7 through a bar to push the socket by the bar, or a device for installing one cylinder to both sockets in one socket 7 to push the socket through the bar It has been proposed, but this is not only complicated configuration but also difficult to manufacture and expensive because one or two cylinders should be installed in one socket (7).

Each socket 7 has a spring 5 interposed between the upper frame 3 and the lower frame 1, and the tension of each spring 5 may be slightly different. As a result, each socket 7 may be slightly different in height. If the height is different, pushing in the same amount (force) may result in a case in which the semiconductor memory chip cannot be properly placed in the less pressed socket 7 or a normal ejection may occur. On the contrary, while pushing in the same amount (force), if the socket 7 is pushed above a predetermined push limit value, an excessive force is applied to the socket 7, which causes the socket 7 to be broken.

The present invention has been proposed to solve the above problems, and can push a plurality of sockets at the same time, and to control the degree of pushing each socket individually, thereby reducing the structure of the socket with the correct pushing operation The purpose is to provide a multi-socket pusher that can increase the seating rate of the device without giving.

Referring to the assembly process of the multi-socket pusher according to the embodiment of the present invention configured as described above are as follows.

First, the clamp and the clamp base 18 are assembled, respectively.

The clamp clamps the plurality of first shafts 14, as shown in FIGS. 3A and 3B, in which two horizontal bars 10 are positioned in parallel with each other, and three vertical bars 12 are arranged in two. The two horizontal bars 10 are coupled to both ends and the middle portion of the horizontal bar 10 at a right angle to the parallel to each other are installed in the lower portion of the two horizontal bars (10). A plurality of first shafts 14 are installed so as to be vertically upward from both ends (edge portions) of the two horizontal bars 10, and the lowest end of the first shaft 14 is locked by a lock bracket 16. ) Is installed at the bottom of the vertical bar 12.

In the case of the clamp, three vertical bars 12 are placed at each end and middle portions of the two horizontal bars 10 in a small angle, and then bolted, and then both ends of the two horizontal bars 10 and The first shaft 14 is press-fitted into a hole (not shown) formed in the two vertical bars 12 fastened thereto, and the bottom end of the first shaft 14 is fixed with the locking bracket 16 and the bolt. The locking bracket 16 is preferably made of a soft material such as rubber.

Meanwhile, as shown in FIGS. 4A and 4B, the clamp base 18 has a plurality of pushing holes 18a formed in the same shape at equal intervals, and the support base 28 is fixed to both sides. A hole 20 for forming a hole is formed, and a hole 22a through which the second shaft 38 penetrates is formed at a position spaced apart from the hole 20 by a predetermined distance, and a circular guide bushing receiving groove 22 is formed. It is formed while wrapping the hole 22a.

In the case of the clamp base 18, the guide brackets 26 are fastened to both sides of the plurality of pushing holes 18a with bolts 26a, and both sides of the plurality of pushing holes 18a (that is, the leftmost side). And the bracket 24 is fastened to the bolt (24a) to the outside of the guide bracket 26 fastened to the right side. Here, one side of the guide bracket 26 and the bracket 24 is formed with holes for press-fitting the hinge shaft 48 at the same height.

Then, as shown in FIG. 5, the clamp base 18 and the pedestal 30 are coupled by using the support 28 and the bolt 28a, and through the shaft movement hole 30a of the pedestal 30. The first shaft 14 of the clamp penetrates upward.

6A, the shaft bushing 32 surrounding the first shaft 14 protruding upwardly through the shaft movement hole 30a of the pedestal 30 is fixed on the pedestal 30. Fit the clamp assembly. Accordingly, the first shaft 14 is smoothly moved by the bearing inserted in the shaft bushing 32.

Subsequently, as shown in FIG. 6B, the cylindrical spring bushing 34 is inserted into the uppermost end of the first shaft 14, and then tightened with a bolt 34a, and the clamp base 18 as shown in FIG. 7. Insert the guide bushing (36) into the guide bushing insertion groove (22).

Then, as shown in FIGS. 8A and 8B, the second shaft 38 is connected to the lower first shaft 14 through the center hole (not shown) and the hole 22a of the guide bushing 36. Contact. Accordingly, one end of the second shaft 38 is in surface contact with the upper end of the spring bushing 34 and the other end of the second shaft 38 penetrates through the guide bushing 36 so as to pass through the clamp base 18. It protrudes upward through the hole 22a of (). Thus, the spring cap 40 in which the spring 42 is installed is inserted into the other end of the second shaft 38.

As shown in FIG. 9A, the vertical bars 46 are applied to the upper ends of the two second shafts 38 protruding from the left side of the clamp base 18, and protrude from the right side of the clamp base 18. The vertical bars 46 are placed on the upper surfaces of the two second shafts 38, and both ends of the driving bars 44 are horizontally contacted with both ends of the vertical bars 46 on the left and right sides thereof. The log drive bar 44 and the vertical bar 46 and the second shaft 38 are fastened to each other. Here, as shown in FIG. 9B, a plurality of recessed grooves 44a are formed in the driving bar 44 at equal intervals, and holes 44b are formed at both ends of the driving bar 44. Bottom surfaces of both end portions of the driving bar 44 having the holes 44b are recessed in a predetermined portion in the form of tracers. The concaved portion is placed on both ends of the vertical bar 46.

Next, as shown in FIGS. 10A and 10B, the hinge shaft 48 is horizontally inserted through the holes of the bracket 24 and the plurality of guide brackets 26 installed in the clamp base 18, and then the bolt ( 48a) the bracket 24 and the hinge shaft 48 are fastened to each other.

In that state, the leveling bracket 50 and the lever 54 are mutually engaged. That is, as shown in FIG. 11A, the leveling bracket 50 and the lever 54 are fastened by a fastener 58 such as a bolt. Here, the leveling bracket 50 is formed in the body portion is stepped, as shown in Figure 11b, the push amount adjusting portion 60, such as a bolt (preferably a hexagon wrench bolt) is fastened to one side surface stepped downward A fastening hole 50a is formed, and a hole 50b to which the fixing member 70, such as a bolt or pin, is fastened is formed at one end of which is stepped downward, and the lever ( A hole 50c for engagement with 54 is formed. In addition, a lower portion of the leveling bracket 50 is excavated to be curved at a predetermined value, and a latch 52 is formed on which the hinge shaft 48 is placed. Meanwhile, the lever 54 is formed in a declination shape, but a hole (not shown) in which the fastener 58 is fitted is formed at a central portion thereof, and protrusions 56 are formed at opposite sides of the lever 54. The protrusions 56 are installed on opposite sides of the lever 54 via a bearing.

The leveling bracket 50 and the lever 54 coupled to each other as described above are fixed to the hinge shaft 48 as shown in FIGS. 12A and 12B. That is, as the latching tongue 52 of the leveling bracket 50 holds the hinge shaft 48, the hinge shaft 48 is inserted into the latching tongue 52 and the stepped downward of the leveling bracket 50. One side is positioned on the drive bar 44.

Thereafter, as illustrated in FIG. 13, one side portion of the leveling bracket 50 downwardly fastens with the driving bar 44 by using the push amount adjusting unit 60. That is, when the push amount adjusting unit 60 is inserted into the fastening hole 50a of the leveling bracket 50 and enters into the corresponding recessed groove among the plurality of recessed grooves 44a of the driving bar 44, the leveling bracket ( The coupling between the 50 and the drive bar 44 is made.

Then, as shown in FIG. 14, after the handler device programmer is installed between the clamp base 18 and the pedestal 30, a plurality of sockets are mounted in the corresponding mounting site. Thereafter, when the heights of the plurality of sockets are the same as those of the mounted plurality of sockets, it is not necessary to operate the push amount adjusting unit 60, but the heights of the plurality of sockets are slightly different. The push amount adjusting unit 60 is operated to adjust the height of the protrusion 56 of the lever 54.

That is, in FIG. 15, when the heights of the plurality of sockets are slightly different, the height of the corresponding protrusion 56 with respect to the other socket may be adjusted based on the height of one socket. In other words, when the push amount adjusting portion 60 of the leveling bracket 50 coupled with the lever 54 to adjust the height of the protrusion 56 is slightly tightened, the latch 52 of the leveling bracket 50 Since the hinge shaft 48 is rotated slightly upward with respect to the axis to slightly raise the lever 54 of the leveling bracket 50, the height of the protrusion 56 is slightly increased. On the contrary, when the push amount adjusting unit 60 is slightly loosened, the latch tongue 52 rotates slightly in the opposite direction to lower the lever 54 of the leveling bracket 50 slightly, so that the height of the protrusion 56 is increased. Will be slightly lower. In this manner, after the height of the lever 54 is properly adjusted by the respective push amount adjusting units 60, the fixing member 70 is operated to fix the present state of the operated push amount adjusting unit 60. Let's do it.

In this way, the heights of all the levers 54 are adjusted appropriately.

After adjusting the heights of all the levers 54 by operating the respective push amount adjusting units 60, as shown in FIG. 16, the adapter cap 68 is mounted between the protrusions 56 and the socket. In other words, while placing the adapter cap 68 on the upper frame of the socket, both inwardly curved portions of the adapter cap 68 are positioned to abut the protrusion 56. In this case, the adapter cap 68 may not be mounted, but when the protrusion 56 directly presses the edge of the upper frame of the socket 10, the portion pressed by the protrusion 56 receives the most force. It may be damaged. Thus, the adapter cap 68 is employed to solve this.

In the multi-socket pusher of the present invention assembled in the manner described above, two drive bars 44 and two hinge shafts 48 are provided, respectively, which may be one or three or more, if necessary. . If the bar 44 and the hinge shaft 48 are made of one or three or more, respectively, the number of the first and second shafts 14 and 38 will be correspondingly two or six or more, respectively. Such modification is sufficiently configurable by the configuration and assembly process of the present invention described above.

In addition, when the multi-socket pusher of the present invention assembled in the manner described above is mounted on the handler, it should be considered that there is a certain gap between the clamp and the lower structure of the clamp to allow the clamp to move up and down. do.

Next, the operation of the multi-socket pusher according to the embodiment of the present invention will be described with reference to FIGS. 17 to 21.

17 is a perspective view illustrating a state in which the multi-socket pusher is not pushed according to an embodiment of the present invention, and FIG. 18 is a side view of FIG. 17, in which the state is not pushed to each socket as in FIG. 16. On the other hand, the height of the projection 56 of the lever 54 is appropriately adjusted, and such a state is assumed to be an initial state.

In this initial state, when the push operation is performed, the power transmitted to the multi-socket pusher of the present invention is transmitted from the cylinder (not shown) mounted on the handler to the first shaft 14 of the clamp. Accordingly, the first shaft 14 rises a predetermined value in the upward direction, and the first shaft 14 is brought into surface contact with the spring bushing 34 on the uppermost end of the first shaft 14 by the rising of the first shaft 14. The two shafts 38 rise in a predetermined value in the upward direction as shown in Figs. 19 and 20.

As the second shaft 38 is raised, as shown in FIGS. 19 and 20, the driving bar 44 ascends slightly upwards as a whole. As a result, the rear end of the leveling bracket 50 (that is, the push) is increased. The amount of the adjustment portion 60 is fastened slightly rises, and the front end of the leveling bracket 50 (that is, the portion where the lever 54 is engaged) is the hinge shaft 48 as shown in FIG. The shaft will rotate slightly downward.

The lever 54 fixed to the front end of the leveling bracket 50 is also lowered vertically by the downward rotation of the front end of the leveling bracket 50 so that the projections 56 formed on both inner surfaces of the lever 54 are vertically lowered. The adapter cap 68 will be pressed. In the initial state, the protrusion 56 may contact the inwardly curved portion (curve) of the adapter cap 68 or may be slightly separated. This depends on the adjustment amount of the push amount adjustment unit 60.

As a result, the adapter cap 68 pushes the edge of the upper frame of the socket evenly throughout.

Thereafter, when the push operation is completed, the first shaft 14 is lowered to return to the initial state, and the spring bushing 34 at the uppermost end of the first shaft 14 is lowered by the lowering of the first shaft 14. The second shaft 38, which is in surface contact with the N, also returns to the initial state as shown in FIGS.

Subsequently, the driving bar 44 descends to return to the initial state by the lowering of the second shaft 38, and the leveling bracket 50 also returns to the initial state. In the case of the leveling bracket 50, the rear end of the leveling bracket 50 (that is, the portion where the push amount adjusting unit 60 is fastened) is slightly lowered to return to the original initial state, and the leveling bracket 50 The front end portion (i.e., the portion where the lever 54 is engaged) returns to its initial state by slightly raising and rotating around the hinge shaft 48 as shown in FIG.

By the upward rotation of the front end of the leveling bracket 50, the lever 54 fixed to the front end of the leveling bracket 50 also rises slightly vertically to release the push on the socket. Therefore, the upper frame of the socket is raised to its original position by the elastic force of the spring provided between the upper frame and the lower frame of the socket.

As a result, the adapter cap 68 located on the upper frame is also raised, and the raised adapter cap 68 returns to the initial state of contact with or slightly separated from the protrusion 56 of the lever 54. .

On the other hand, the present invention is not limited only to the above-described embodiment, but can be modified and modified within the scope not departing from the gist of the present invention, the technical idea to which such modifications and variations are also applied to the claims Must see

As described in detail above, according to the present invention, it saves time to be programmed by simultaneously pushing a plurality of sockets mounted in the device programmer (Rom Writer) for the handler using one power source or a drive source (for example, a cylinder, a motor). The amount of push of each socket can be adjusted individually, so that the push to each socket with different heights or tensions can be precise. This not only minimizes the failure rate of sockets, but also increases productivity.

In particular, the adapter cap adopted for each socket evenly transmits the force to the upper frame of the socket so that the socket is uniformly pushed without being biased or biased to one side and the buffer structure does not overload the structure of the socket. By providing a prolongation of the socket and has the advantage of solving the problem that the device is not properly inserted or ejected.
