Detailed Description

The contents of the present invention will be further described in detail with reference to the specific embodiments, and fig. 2 and fig. 3 respectively show a schematic perspective view and a top view of the clamping tool for an automotive display screen according to the present invention, and it can be seen that the clamping tool mainly comprises a substrate 1, a Z-direction supporting top portion 2, an X-direction limiting portion 3, and a Y-direction limiting portion 4. The Z-direction supporting part 2 includes a first supporting member 21 and a second supporting member 22, both detachably fixed to the upper plane of the substrate 1, and sequentially distributed along the X-direction. The X-direction limiting portion 3 includes 4 limiting baffles 31, and is also fixedly connected to the substrate 1, and each two of the limiting baffles are in one group and symmetrically distributed on two sides of the first supporting member 21 and the second supporting member 22 along the Y-direction. The Y-direction stopper portion 4 includes a first sliding portion 41, a second sliding portion 42, and a power driving portion 43. The first glide 41 includes a first glide plate 411, a first tip assembly 412, a second tip assembly 413, and a third tip assembly 414. The first slide plate 411 is directionally displaceable along the Y direction. The first tip assembly 412, the second tip assembly 413, and the third tip assembly 414 are sequentially disposed on the first sliding plate 411 along the X direction. The second glide 42 includes a second glide plate 421, a fourth tip assembly 422, a fifth tip assembly 423, and a sixth tip assembly 424. The second sliding plate 421 can also perform directional displacement along the Y direction. The fourth tip assembly 422, the fifth tip assembly 423, and the sixth tip assembly 424 are sequentially disposed on the second sliding plate 421 along the X direction. Under the action of the power driving part 43, the first sliding part 41 and the second sliding part 42 synchronously perform displacement motion, and when the first sliding part 41 moves oppositely relative to the second sliding part 42, the clamping operation of the automobile display screen is realized; when the first sliding part 41 moves back to back relative to the second sliding part 42, the releasing operation of the automobile display screen is realized. Therefore, on one hand, the simultaneity and the synchronism of the movement of the first sliding part 41 and the second sliding part 42 are effectively ensured, the accuracy of the relative positions of the automobile display screen after the clamping is finished is ensured, and the subsequent testing work is facilitated to be smoothly carried out; on the other hand, the power driving part 43 needs lower purchase cost compared with two independent cylinders, so that the manufacturing cost of the clamping tool is reduced; and it occupies littleer installation space, does benefit to and wholly carries out layout design to centre gripping frock.

The working principle of the clamping tool for the automobile display screen is as follows: when the automobile display screen is clamped, the power driving part 43 acts, and the first sliding part 41 moves relative to the second sliding part 42 in the opposite direction until all the tip assemblies (including the first tip assembly 412, the second tip assembly 413, the third tip assembly 414, the fourth tip assembly 422, the fifth tip assembly 423 and the sixth tip assembly 424) are in contact with the side wall of the automobile display screen and are tightly pressed; subsequently, the lighting test is performed on the automobile display screen. After the test is finished, the power driving part 43 operates again, so that the first sliding part 41 moves back and forth relative to the second sliding part 42, and the clamping of the automobile display screen is released.

As a further refinement of the structure of the clamping tool for an automobile display panel, the power driving unit 43 is preferably mainly composed of a linear motor (not shown), a transient sliding unit 431, a first link 432, and a second link 433. The transition sliding assembly 431 includes a transition sliding plate 4311 and a first sliding rail sliding block assembly 4312. The first slide rail slider assembly 4312 is comprised of a first slide rail and a first slider. The transition sliding plate 4311 is disposed right above the base plate 1, and can perform directional displacement motion along the X direction under the combined action of the first sliding rail sliding block assembly 4312 and the linear motor. In the Y direction, the first sliding part 41 and the second sliding part 42 are respectively arranged on two sides of the transition sliding assembly 431. The first connecting rod 432 is hinged between the transition sliding plate 4311 and the first sliding plate 411; the second link hinge 433 is coupled between the transition glide plate 4311 and the second glide plate 421 (as shown in fig. 2, 3, 4, 5). Through adopting above-mentioned technical scheme to set up, not only realized linear electric motor to the simultaneous drive of first portion 41 and the second portion 42 that slides, and under this prerequisite, realized the enlargement of thrust to the requirement of linear electric motor output thrust has been reduced.

It should be noted that, in addition to the above-mentioned linear motor, the linear motion element may also be a linear motor module, a pneumatic cylinder, a hydraulic cylinder, or the like according to practical situations.

In order to ensure the directionality of the movement of the first sliding portion 41, a second sliding rail slider assembly 415 is further added. The second slide rail slider assembly 415 is composed of a second slide rail and a second slider, wherein the second slide rail is detachably fixed on the base plate 1, and the second slider is detachably fixed on the lower plane of the first sliding plate 411 (as shown in fig. 2). Thus, the first sliding portion 41 is effectively prevented from being biased in the process of approaching toward the display screen of the automobile, and the first tip assembly 412, the second tip assembly 413 and the third tip assembly 413 are ensured to be simultaneously contacted with the side wall of the display screen of the automobile.

Of course, for the same purpose, the second sliding portion 42 may be provided with a third sliding rail block assembly 425, similar to the first sliding portion 41. The third slide rail slider assembly 425 is composed of a third slide rail and a third slider, wherein the third slide rail is detachably fixed on the base plate 1, and the third slider is detachably fixed on the lower plane of the second sliding plate 421 (as shown in fig. 2).

Because of the smoothness nature of the centre gripping frock is put into to the automotive display screen, prevent considering in the aspect of the "jamming" phenomenon, can also be provided with first direction inclined plane 311 on limit baffle 31, and form along X direction beveling by the top of limit baffle 31. The inclination angle of the first guide slope 311 is controlled to be 45-60 deg. (as shown in fig. 6).

As a further optimization of the above technical solution, a wear-resistant coating (not shown in the figure) may be further disposed on the first guide slope 311. The wear-resistant coating can effectively reduce the relative friction coefficient between the limiting baffle plate 31 and the automobile display screen, so that the service life of the limiting baffle plate 31 is prolonged as much as possible, and the later maintenance cost of the clamping tool is reduced.

Of course, as another modified design of the above technical solution, the X-direction limiting portion 3 further includes 4 wear plates 32, which are detachably mounted on the limiting baffle 31 in a one-to-one correspondence. And the wear plate 32 includes a second guide ramp 321. The second guide slope 321 is chamfered in the X direction from the tip of the wear plate 32 (as shown in fig. 7). Therefore, when the abrasion phenomenon occurs, only the abrasion resistant plate 32 needs to be replaced by a new one, so that the later maintenance difficulty and the later maintenance cost of the clamping tool are greatly reduced.

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
