1. Technical Field
The present disclosure relates to testing modules, and particularly to a testing module for testing the wear-resisting property of portable electronic device.
2. Description of Related Art
The outer surfaces of portable electronic devices (e.g., mobile phones) need to be able to withstand wear and tear. Thus, the wear-resisting property should be tested e.g., to ensure the portable electronic devices keeps a good appearance for some time.
A known testing apparatus includes a frictional member. The frictional member is driven to move repeatedly on the outer surfaces of the tested product in a predetermined time to judge the wear-resisting property of the product surface. However, this known testing module cannot change the movement stroke, and only can test a particular portable electronic device with a fixed size or shape. Each particular testing apparatus corresponds to one kind of portable electronic device which has a particular size or shape. Thus, during the process of testing, a plurality of testing apparatuses is inevitably implemented to test various kinds of portable electronic devices. It results in high costs and decreases the efficiency of the whole test.
Therefore, there is room for improvement within the art.
Many aspects of the testing module can be better understood with reference to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the testing module. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.
The testing module 100 shown in
A number of clamping members 22 are positioned on the worktable 20. Each clamping member 22 is in two parts, opposite to each other, for clamping the tested product.
The drive module 30 includes a motor 32, a rotor 34, and a latching member 36. The latching member 36 is formed on one end of the rotor 34. When the motor 32 runs, the rotor 34 rotates, which rotates the latching member 36. The latching member 36 extends through the top plate 12, and is connected to the transmission module 40 for driving the transmission module 40 to rotate, and the transmission module 40 transforms rotary motion into linear reciprocating motion.
Referring to
The nut 46 is substantially T-shaped, and is slidably received in the groove 442. The nut 46 defines a threaded hole 462 and a latching hole 464. The axis of the threaded hole 462 is parallel with the groove 442 and perpendicular to that of the latching hole 464. The bolt 48 is inserted into the through hole 444 and the groove 442, and is screwed into the threaded hole 462. The bolt 48 can be rotated to adjust the location of the nut 46 relative to the rotational plate 44.
The connecting plate 49 is attached to the rotational plate 44. Referring to
The sliding module 50 includes two guiding rails 52, two sliding blocks 54, and a support plate 56. The guiding rails 52 are mounted on the top plate 12, and the sliding blocks 54 are slidably engaged in the guiding rails 52. The sliding blocks 54 are mounted to the two sides of the support plate 56. The other end of the connecting plate 49 is mounted to the middle portion of one side of the support plate 56. Since the rotational plate 44 moves the connecting plate 49 and the guiding rails 52 cannot rotate, the connecting plate 49 drives the support plate 56 and the sliding blocks 54 to slide in a reciprocating manner relative to the guiding rails 52.
Referring to
Each frictional member 70 includes a rod body 72, a frictional head 74 and a counterweight 76. The holding member 69 is clamped to the rod body 72. The frictional head 74 is formed at the lower end of the rod body 72. The counterweight 76 is positioned at the opposite end of the rod body 72 for adjusting the amount of pressure applied by the frictional head 74 to the tested product.
During testing, the tested products are held in the clamping members 22, the frictional members 70 extend through the holding members 69, and are positioned on the connecting modules 60. The height of each frictional member 70 can be adjusted in the seat 68 according to the height required for the tested product, and in addition, the stroke of the connecting plate 49 is fully adjustable for testing different products
It is to be understood that even though numerous characteristics and advantages of the present embodiments have been set forth in the foregoing description, together with details of structures and functions of various embodiments, the disclosure is illustrative only, and changes may be made in detail, especially in the matters of shape, size, and arrangement of parts within the principles of the present invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
