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.

SUMMARY OF THE INVENTION The present invention has been proposed to solve the above-described problems, and an object thereof is to provide a multi-socket pusher capable of simultaneously pushing a plurality of sockets and individually controlling the degree of pushing each socket. .

The multi-socket pusher according to the present invention includes a clamp base 10 having a plate-shaped center portion installed on a device programmer (not shown) in which a plurality of sockets are mounted; A shaft 12 having one end fixed vertically to the side (edge portion) of the clamp base 10 and vertically moving up and down by power provided from a power source (or drive source) such as a cylinder or a motor; The clamping plate is installed flat on the upper surface of the clamp base 10, the portion facing the position on which the socket is mounted is punched in the longitudinal direction, the clamping plate formed with a plurality of push amount adjustment holes (14c) around the perforated portion (14); A plurality of clampers 16 fitted around the perforated portion 24 of the clamping plate 14 at the bottom of the clamping plate 14 and mounted on the plurality of sockets and clamped as if they surround the socket. ; And a plurality of push amount adjusting units 18 connected to the plurality of clampers 16 through the plurality of push amount adjusting holes 14c to adjust the push amounts for the respective sockets.

Here, the clamp base 10 is a quadrangular plate-shaped perforated center, a hole 10a for coupling with the shaft 12 is formed in the corner portion, the clamping plate (near the hole 10a) A hole 10b for engaging with 14 is formed. The clamp base 10 is coupled to the shaft 12 by bolts 26.

In addition, a hole 14a is formed at the corner of the clamping plate 14 by the bolt 28 to be coupled to the clamp base 10. A central hole 24 in the longitudinal direction (horizontal direction) is formed in the center portion of the clamping plate 14, the hole 24 is a portion facing the socket mounting position (i.e., the clamper 16). Is formed). In the present invention, the long hole 24 is shown in two, but the number may be one or three or more depending on the situation.

In addition, in the arrow direction (A direction) in FIG. 3, the upper and lower positions of the long holes 24 are fixed to the left and right position fixing holes 14b by the positions where the sockets are mounted for engagement with the flange of the clamper 16. Is formed, and between the left and right position fixing holes 14b, a push amount adjusting hole 14c into which the push amount adjusting unit 18 is inserted is formed.

In addition, the clamper 16 is formed in the form of a delimiter having a center portion drilled and flanges on both sides. The clamper 16 is coupled to the clamping plate 14 through left and right position fixing holes 16a formed in both flanges, respectively, which are fitted by position pins 22. In addition, a push amount adjusting hole 16b is formed between the left and right fixing holes 16a respectively formed in the flanges on both sides to vertically fit the push amount adjusting unit 18. The clamper 16 of the above-described type is provided with the number of sockets which can be simultaneously mounted to the device programmer.

The push amount adjusting unit 18 is made of a bolt such as a hexagon wrench bolt as shown in FIG. The bolt is installed through the flange of the clamper 16 through the push amount adjusting hole 14c of the clamping plate 14 and the push amount adjusting hole 16b of the clamper 16. Between the clamping plate 14 and the flange of the clamper 16, that is, the push amount adjusting hole 14c and the push amount adjusting hole (when the clamping plate 14 and the clamper 16 are coupled to each other) 16c) is interposed between the elastic member 20, such as a spring.

Here, the push amount control unit 18 and the elastic member 20 serves to push the socket in place exactly. If you do not press the right position, the socket may be broken or the socket may not be pushed correctly. This is to prevent this. The push amount adjusting unit 18 to adjust the push amount of each socket, the elastic member 20 is inserted into the tension because it is easy to adjust the push amount.

The other side of the shaft 12 fixed to the corner of the clamp base 10 is clamped by two horizontal bars 30 and three vertical bars 32 and 33. That is, two horizontal bars 30 are positioned in parallel to each other, and three vertical bars 32 and 33 are coupled to both ends and middle portions of the two horizontal bars 30, but with respect to the horizontal bars 30. It is installed at the lower portion of the two horizontal bars 30 in parallel to each other at a right angle. The lower end of the other end of the shaft 12 is installed at the bottom of the vertical bar 32 by a lock bracket 36.

More specifically, the three vertical bars (32, 33) to each end and the middle portion of the two horizontal bars 30 in a small angle to each other holes (ie, 30c and 32b, 30b and 33b) Is fixed with a bolt (34). Thereafter, the other end of the shaft 12 is press-fitted into the holes 30a and 32a formed at both ends of the two horizontal bars 30 and the two vertical bars 32 fastened thereto, and then the shaft 12 ) Is fixed to the bottom of the bracket with a locking bracket (36). The locking bracket 36 is preferably made of a soft material such as rubber. A hole 32c in a direction orthogonal to the hole 32a is formed in the periphery of the hole 32a of the vertical bar 32 positioned on the left and right side among the three vertical bars 32 and 33. The locking bracket 36 is bolted through the hole 32c.

A hole 33a is formed in the center of the vertical bar 33, which is located in the middle among the three vertical bars 32 and 33, and the moving shaft of the cylinder 42 which provides the push force to the hole 33a. Is press-fitted.

The cylinder 42 is fixed to a central portion of the bottom surface of the pedestal 40 installed horizontally between the clamp base 10 and the horizontal bar 30. Holes 40a through which the shaft 12 penetrates are formed at the corners of the pedestal 40, and holes 40b for fixing the shaft bushings 38 are formed around the holes 40a. Is formed.

In the embodiment of the present invention, the cylinder 42 is shown as a power source or drive source, but may be a motor other than the cylinder. In the case of a motor, the motor may be regarded as being fixed to the center of the bottom surface of the pedestal 40.

In addition, the shaft bushing 38 is also fastened to the upper end of the shaft 12 fixed to the edge of the clamp base 10. The shaft bushing 38 is a device programmer (ROM writer) as shown in FIG. When installed between the clamp base 10 and the pedestal 40, it is interposed between the edge of the device programmer and the edge of the clamp base 10. Accordingly, the shaft 12 is smoothly moved by a bearing inserted in the shaft bushing 38. In addition, a certain distance is maintained between the clamp base 10 and the upper shaft bushing 38 for vertical movement of the shaft 12.

In addition, when the multi-socket pusher of the present invention configured as described above is mounted on the handler and the vertical structure of the vertical bar (32, 33) and the lower structure of the vertical bar (32, 33) for vertical vertical movement of the shaft (12); Should be considered to have some gap.

Next, the operation of the multi-socket pusher according to the embodiment of the present invention will be described with reference to FIGS. 6 to 8.

6 is a state in which the multi-socket pusher and the device programmer of the present invention are coupled to each other, and a plurality of sockets 46 are mounted on the device programmer.

Individual push amount adjustments to the plurality of sockets 46 are made before or after the clamp base 10 is installed on the device programmer. The following description assumes that the individual push amount adjustment is performed after the clamp base 10 is installed on the device programmer.

Initially, the operator installs the clamp base 10 on a device programmer with a number of sockets 46 mounted thereon, joining the edge of the clamp base 10 to the top of the shaft 12 with the bolt 26. Let's do it.

Then, a plurality of clampers 16 are individually coupled to the clamping plate 14 using the positioning pins 22. After the coupling between the clamper 16 and the clamping plate 14 is made, the elastic member 20 and the push amount adjusting unit 18 are coupled to positions corresponding to the respective sockets 46.

Before engaging the clamping plate 14 and the clamp base 10 with each other, the operator observes the height of the plurality of sockets 46 seen on the clamp base 10 and adjusts the push amount accordingly. The unit 18 is operated. For example, tightening the push amount adjusting portion 18 made of a hexagon wrench bolt will increase the amount of socket push more than the tightened amount less.

In this manner, when the operation of all the push amount adjusting unit 18 is completed, the clamping plate 14 and the clamp base 10 are coupled to the bolt 28. Thereby, it will be in the state like the side view of FIG.

After that, when the push operation is performed, first, the cylinder 42 under the pedestal 40 is operated by the operation command signal, so that the moving shaft having one end pressed into the center portion of the vertical bar 33 moves downward. The vertical value is moved vertically. Accordingly, one end is fixed to the corner portion of the clamp base 10 and the other end of the shaft 12 fixed to the corner portion of the horizontal bar 30 and the vertical bar 32 is vertically moved downward in a predetermined value. .

Thus, the clamping base 10 fixed to the shaft 12 and the clamping base 10 and the clamping plate 14 coupled to the upper surface of the clamping base 10 are vertically lowered, whereby the clamping plate 14 as shown in FIG. The clamper 16, which is fastened through the respective position fixing holes 14b and the push amount adjusting holes 14c in the long hole 24 of the c), descends vertically to press the upper frame of the lower socket 46.

In particular, since the elastic member 20 such as a spring is inserted between the clamping plate 14 and the clamper 16 and is subjected to tension, the push amount adjustment unit 18 may be further tightened due to failure in adjusting the push amount. Even if it is loosened or loosened more, the amount of push is reduced to some extent by the tension of the elastic member 20.

Thereafter, after the push operation is completed, the state returns to the state as shown in FIG.

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, a plurality of sockets mounted in a device programmer for a handler (eg, a ROM writer) are selected as a whole by simultaneously pushing a plate and a power source or a driving source (for example, a cylinder, a motor, etc.) simultaneously. The force is applied to the sockets and the amount of pushing of each socket can be adjusted individually, as well as the tension is retained by the spring insert, which allows the push to each socket with different heights or tensions to be precise. This not only minimizes the failure rate of sockets, but also increases productivity.

In addition, programming and socket push for a socket can be simultaneously processed for a plurality of sockets, thereby reducing the time required for programming and chip ejection.

In particular, the clamper is installed to surround the socket, the clamping plate to press the clamper is also in the form of a flat plate so that the same force is transmitted to the upper frame of the socket during the push operation. As a result, the socket is not pushed to one side or pushed unbiased, and the socket can be pushed uniformly.
