Detailed Description
In the following description, reference is made to or as indicated in the accompanying drawings, which are merely for emphasis instead of limiting the description in which they refer.
Referring to fig. 1 to 6, fig. 1 and 2 are schematic assembly diagrams of a chip pressing device according to the present invention; FIG. 3 is a schematic view showing the pressing unit and the body of the chip pressing device of the present invention separated from each other; FIG. 4 is a schematic diagram showing the chip pressing device of the present invention being fixedly disposed on the chip carrier; fig. 5 and 6 are exploded views of the chip pressing device of the present invention. As shown in fig. 1, the chip pressing device 1 includes a body 10, a pressing unit 20 and a clamping assembly 30.
As shown in fig. 1 to 3, at least one first connection assembly 11 is disposed on one side of the body 10. The pressing unit 20 is provided with a second connecting component 21, and the pressing unit 20 is detachably disposed on the side of the body 10 provided with the first connecting component 11. The second connecting component 21 can be connected with the first connecting component 11, and the pressing unit 20 can be connected with the first connecting component 11 through the second connecting component 21, so as to be fixed on one side of the body 10. The pressing unit 20 has a contact structure 201 for pressing the chip B disposed on the chip carrier a. The engaging component 30 is disposed on the body 10. The engaging component 30 can be operated to engage or disengage the chip pressing device 1 and the chip carrier a, i.e. the body 10 can be disposed above the chip carrier a where the chip B is disposed by the engaging component 30.
As shown in fig. 4, when the pressing unit 20 is fixedly disposed on one side of the body 10, and the body 10 is fixed above the chip carrier a by the engaging component 30, the contact structure 201 of the pressing unit 20 will correspondingly press one side of the chip B opposite to the chip carrier a; at this time, the related personnel can carry out related detection operation on the chip B through the chip bearing device A. In practical applications, the chip carrier a may be various electrical sockets (sockets) for connecting with the chip B, and the form of the chip B may also be changed according to the requirements.
In the above description, a practical example will be given below to describe the possible embodiments of the body 10, the first connecting component 11, the pressing unit 20, the second connecting component 21 and the engaging component 30 in detail. As shown in fig. 6, one side of the body 10 may be concave to form a locking groove 12. The first connecting component 11 may include four first magnetic members 111, where the first magnetic members 111 are disposed on the body 10, and the first magnetic members 111 are correspondingly disposed in the engaging grooves 12.
As shown in fig. 2 to 6, the pressing unit 20 may have a locking structure 202, and a contact structure 201 is formed by protruding one side of the locking structure 202. The shape of the clamping structure 202 corresponds to the shape of the clamping groove 12, and the clamping structure 202 can be correspondingly clamped and arranged in the clamping groove 12; when the engaging structure 202 is fixedly disposed in the engaging groove 12, the contact structure 201 is correspondingly exposed at one side of the body 10.
The second connection component 21 may include four second magnetic attraction members 211, where each second magnetic attraction member 211 can attract each first magnetic attraction member 111, for example, each first magnetic attraction member 111 and each second magnetic attraction member 211 may be magnets with different polarities, or one of the first magnetic attraction member 111 and the second magnetic attraction member 211 is a magnet, and the other is a member that can be attracted by the magnet. When the engaging structure 202 is engaged and fixedly disposed in the engaging groove 12, each first magnetic attraction member 111 will attract each second magnetic attraction member 211, and the pressing unit 20 will be correspondingly and fixedly disposed on one side of the body 10.
The shape, size, number, etc. of the first magnetic member 111 and the second magnetic member 211 can be changed according to the requirement, and are not limited to the illustration. The manner of connecting the first connecting element 11 and the second connecting element 21 is not limited to the magnetic attraction manner, and it is within the scope of the present embodiment if the first connecting element 11 and the second connecting element 21 can be connected to each other and fixed to each other, and the first connecting element 11 and the second connecting element 21 can be directly separated by manual operation. For example, the first connecting component 11 may not have the first magnetic component 111, the second connecting component 21 may not have the second magnetic component 211, and the first connecting component 11 and the second connecting component 21 may be the engaging groove 12 and the engaging structure 202, respectively, that is, the first connecting component 11 and the second connecting component 21 may be directly connected by being engaged with each other.
As described above, since the pressing unit 20 can be easily detached from the body 10, the user can replace the pressing unit 20 with the corresponding contact structure 201 according to the shape and size of the chip B to be pressed. Specifically, in the case that two chips B with different sizes are respectively disposed on two chip carriers a with the same size, a user may simply replace the different pressing units 20, so that the body 10 may be engaged with the chip carriers a with the same size through the engaging component 30, and the chips B with different sizes may be pressed by using the different pressing units 20.
As shown in fig. 3, 5 and 6, it should be noted that, in practical applications, the body 10 may further have a first foolproof structure 13, and the pressing unit 20 further has a second foolproof structure 22. When the first connecting component 11 and the second connecting component 21 are connected to each other, and the pressing unit 20 is fixed to the body 10, the first fool-proof structure 13 and the second fool-proof structure 22 are fixed to each other. Specifically, the body 10 may be concavely formed with a groove adjacent to the engaging groove 12, and the groove is communicated with the engaging groove 12, and the groove may be used as the first foolproof structure 13. The second fool-proof structure 22 may be a protruding structure formed by extending the engaging structure 202. In this way, when the user fixes the engaging structure 202 to the engaging groove 12, the user must make the second foolproof structure 22 correspond to the first foolproof structure 13, so that the engaging structure 202 can be smoothly engaged in the engaging groove 12, and thus the problem that the contact structure 201 is incorrectly pressed against the chip B due to incorrect installation of the pressing unit 20 by the user can be avoided. Of course, the shapes and the arrangement positions of the first fool-proof structure 13 and the second fool-proof structure 22 may be changed according to the requirements, and the embodiments shown in fig. 3, 5 and 6 are only exemplary.
As shown in fig. 4 to 6, opposite sidewalls of the body 10 may be respectively concaved inward to form an operation groove 14. The engaging component 30 may include two engaging members 31 and two elastic members 32. Each of the fastening members 31 may be provided with a pivot shaft 33 pivotally connected to the pivot hole 15 of the body 10. The two snap members 31 may be correspondingly located in the two operation slots 14. One end of each fastener 31 and the chip carrier a may have a fastening structure 311, A1 capable of being mutually fastened. The two elastic members 32 are correspondingly disposed between the two fastening members 31 and the body 10. One end of each elastic member 32 is fixed to the body 10, and the other end of each elastic member 32 is fixed to the clip 31. As for the manner in which the two ends of each elastic member 32 are respectively fixed to the fastening member 31 and the main body 10, for example, as shown in fig. 4 to 6, corresponding slots are formed in the fastening member 31 and the main body 10, and the ends of the elastic members 32 are correspondingly engaged with each other and disposed in the slots, but not limited thereto.
As shown in fig. 7, when each of the fastening members 31 is operated to rotate relative to the main body 10, each of the elastic members 32 located between each of the fastening members 31 and the main body 10 is pressed to generate an elastic restoring force, so that the user can clamp the two fastening members 31 to the chip carrier a in the state of fig. 7. As shown in fig. 4, when the fastening structure 311 of the fastening member 31 is correspondingly fastened with the fastening structure A1 of the chip carrier a, the elastic restoring force generated by each elastic member 32 can make the fastening structure 311 of each fastening member 31 more firmly clamp the fastening structure A1 of the chip carrier a.
In the embodiment, the engaging component 30 has two fastening members 31, and the body 10 clamps the chip carrier a through the two fastening members 31, so as to be fixedly disposed above the chip carrier a, but the components included in the engaging component 30 are not limited thereto. The engaging component 30 may be any structure or may include any member as long as the body 10 is detachably fixed to the chip carrier a.
It should be noted that, in various applications, the chip pressing device 1 may further include a pivot assembly (not shown) fixedly disposed on the body 10, and the pivot assembly of the chip pressing device 1 can pivot with a corresponding pivot assembly (not shown) on the chip carrier a, so that the chip pressing device 1 can be operated to rotate relative to the chip carrier a. When the user operates the chip pressing device 1 to rotate the chip pressing device 1 towards the chip carrier a, and accordingly the chip pressing device 1 is located directly above the chip carrier a, the user can reuse the fastening assembly 30 to fasten the chip pressing device 1 and the chip carrier a, so that the chip pressing device 1 is fixedly disposed directly above the chip carrier a.
Fig. 8 is an exploded view of the chip pressing device set 2 according to the present invention. As shown in fig. 8, the chip pressing device set 2 includes a chip pressing device 1 and a plurality of pressing units 20A and 20B. The chip pressing device 1 includes a body 10 and a locking assembly 30. The body 10 is provided with a first connection assembly 11. Each pressing unit 20A (20B) has a locking structure 202, a contact structure 201, and a second connecting component 21. For the detailed description of the body 10, the engaging member 30, the first connecting member 11, the engaging structure 202, the contact structure 201 and the second connecting member 21 of each pressing unit 20, please refer to the above description, and the detailed description is omitted herein.
In summary, the chip pressing device 1 and the chip pressing device set 2 of the present invention can allow the user to correspondingly replace the pressing units 20 with different contact structures 201 according to different sizes of the chips B, so that the user can press the chips B with different sizes on the same size chip carrier by using the same body 10 and different pressing units 20, and the user does not need to purchase two groups of chip pressing devices 1, thereby reducing the research and development costs of the related research personnel. In contrast, for the manufacturer of the chip pressing device 1, for the chip carrier device a with the same size, the manufacturer may only develop and produce different pressing units 20 without redesigning the whole chip pressing device 1, so as to reduce the production cost and development cost thereof.
The foregoing description is only of the preferred embodiments of the invention and is not intended to limit the scope of the invention, so that all changes which come within the meaning and range of equivalency of the description and drawings are intended to be embraced therein.
