Description

Hook / slot machine for cellular phone case}

The present invention relates to a fastening part processing machine of a mobile phone case, and more particularly, by performing a complex process in a single stroke at a mass production site of small assembly parts, the defective rate of the product is reduced, and the process time is shortened to improve productivity. It relates to a binder processing unit of the mobile phone case.

In general, in the case of a small electronic device including a mobile phone, a hooking method is preferred to a bolting method. In the case of a mobile phone, the coupling between the upper and lower cases in the main body in which the main functions are built, as well as the cover in which the display and the speaker are built, is performed by a hook and a hook groove (hole type). The hook and the hook groove is provided with a plurality in order to promote the coupling force according to the assembly.

In the conventional case, in order to manufacture a small part having a large number of hooks and hook grooves in a site where mass production is required, the injection molding is performed by reflecting the hooks and hook grooves on the mold itself, and the operator performs a finishing process with a hand tool. Due to the wear of the mold, the dimensional accuracy is sharply lowered, and there is a high possibility of product defects due to differences in skill of workers. Deformation of the hook not only delays the working time in the assembly process to the finished product, but also causes other defects such as shaking, cracking and breakage.

In order to solve this problem by relying on the mold itself, it is advantageous to maintain the dimensional accuracy through a separate cutting process because the design conditions are enhanced and complicated, and the burden of cost increase is increased. Dedicated machines that automatically perform complex machining in a series of processes that are put into the process and immediately discharged.

Accordingly, the present invention is to fundamentally solve the conventional problems as described above. As a result of performing a complex process in one stroke at the mass production site of the small assembly parts, the defective rate of the product is lowered, and the process time is shortened to improve productivity. The purpose of the present invention is to provide a fastening machine for the mobile phone case.

The processing bed 50 is formed of a plate material and has a frame 53 for fixing the motor 54 and the cutter blade 56 on the upper surface, and the lower surface is operated by the operation of the cylinder 52 via the slide 50a. Transfer left and right. The cutter blade is driven through a belt connected to the motor 54, and is driven in a state in which one side is protected by an open cylindrical housing 57, and the cutter blade 56 is opened through an opening of the housing 57. It exposes and cuts the hook H of the workpiece | work A.

At this time, in order to discharge the chip (not shown) generated during the cutting process to the outside of the machine is provided with a discharge port (57a) in the rear portion of the housing (57). In this case, as shown in the enlarged view of FIG. 3, the plurality of surfaces are processed in one stroke via the double cutter blade 56, but the cutter blade 56 may be further provided according to the shape of the work A. FIG.

In addition, the copying device 60 according to the present invention is mounted on one end of the processing bed 50, and has a copy roller 62 at a position corresponding to the model M. The copying device 60 detects the outer circumferential surface shape of the model M installed on the conveying bed 20 as the copying device 60 is moved left and right integrally with the processing bed 50. It will be described in detail with reference to Fig. 5 to be described later as a cutting principle. Fig. 4 is a configuration diagram showing an enlarged support according to the present invention.

In Figure 4, the support 40 is a bearing 42, 44 for supporting the guide plate 46 fixed to the bottom of the transfer bed 20 in the vertical direction, and adjusts the bearing force of the bearing 42, 44 The adjusting bolt 48 is provided. The bearings 42 and 44 are rotatably installed on one side of the fixing plates 42a and 44a, respectively, and the fixing plates 42a and 44a are bolted to the guide blocks 41 provided on both sides of the transfer bed 20. Is fastened.

Accordingly, when the transfer bed 20 is moved to the machining position, the guide plate 46 is inserted into the support 40 to prevent the play of the transfer bed 20 by the support bearing 42 and the compression bearing 44. At this time, the guide plate 46 forms an inclined portion 46a at the end to prevent a jam when entering between the support bearing 42 and the compression bearing 44.

5 is a plan view showing a copying device according to the present invention.

In FIG. 5, the copying device 60 includes a copy roller 62 for transporting on the outer circumferential surface of the model M, a base 64 interposing the copy roller 62 at one end, and the base 64. It is fixed to the other end and at the same time to move the left and right, and the first bracket 66, and the second bracket (68) located at the rear end of the first bracket 66 for transferring the base back and forth. The copying device 60 has a copy roller 62 rotatably installed at one end of the base 64, and the other end is received on the first bracket 66. The first bracket 66 allows the base 64 to be finely adjusted in the left and right direction through the left and right adjusting devices 66a at both ends thereof, and includes a plurality of fasteners 66b at the upper end, and the left and right position adjustment is completed.

And a fixed roller 78 for supporting the wire 74. At this time, the weight 76 is provided to vary the weight to adjust the pressure to press according to the shape of the model (M) or the strength and shape of the processing surface.

1 to 6 will be described the operation of the machine according to the present invention.

First, when a switch (not shown) is operated while the work A is loaded on the die 10, the cylinder 14 descends to clamp the work A. FIG. Subsequently, as the enlarged view of FIG. 2 transfers the platen 34 by the operation of the cylinder 32, the platen 34 presses both sides of the workpiece A on the cutting groove 36a on the stroke groove 38a to hook the groove. Perform the machining of (H ') and return to the original position.

Subsequently, when the workpiece A and the model M on the transfer bed 20 are processed and detected by the operation of the cylinder 22, the motor 54 rotates the cutter blade 56 and the cylinder 52. When the cutter blade 56 and the copying device 60 on the processing bed 50 are advanced by the operation of the same, and the model M is conveyed back and forth through the transfer bed 20 along the circumference of the outer surface by the copy roller 62, As shown in the enlarged view of FIG. 3, the cutter blade 56 is interlocked to process the hook H. As shown in FIG. Subsequently, when the transfer bed 20 and the processing bed 50 are sequentially returned to the initial position by the cylinders 22 and 52, the clamp 12 of the die 10 is released to take out the work A. Then another workpiece A is loaded into the die 10 and the above operation is continuously repeated.

If the model of the product needs to be changed, the processing position is finely adjusted by adjusting the adjusting bolt 68 of the copying device 60 while the guide block 10a and the model M on the die 10 are replaced. In addition, after fixing the copy roller 62 with the fixing bolt 69, the workpiece A of the changed type is loaded on the die 10 and operated.

According to the above configuration and operation, the present invention has the effect of improving the productivity by reducing the defect rate of the product and shortening the process time by performing a complex process in one stroke in the mass production site of the small assembly parts.

It is apparent to those skilled in the art that the present invention is not limited to the embodiments described, and that various modifications and variations can be made without departing from the spirit and scope of the present invention. Therefore, such modifications or modifications will have to belong to the utility model registration claims of the present invention.
