In order to make the objects, technical solutions and advantages of the present application more clear, the technical solutions of the present application will be clearly and completely described below with reference to the detailed description of the present application and the accompanying drawings. It should be apparent that the described embodiments are only some embodiments of the present application, and not all embodiments. All other embodiments obtained by a person of ordinary skill in the art without any inventive work based on the embodiments in the present application are within the scope of protection of the present application.

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are exemplary only for the purpose of explaining the present invention, and should not be construed as limiting the present invention.

For convenience in explanation, the description herein uses terms indicating relative spatial positions, such as "upper," "lower," "rear," "front," "left," "right," and the like, to describe one element or feature's relationship to another element or feature as illustrated in the figures.

As shown in fig. 1-6, a device for detecting a light sheet disclosed for an embodiment of the present invention is used for detecting a light sheet, and includes a supporting platform 1 and at least two probe assemblies 5 disposed on the supporting platform 1. The supporting table 1 is used for placing the lamp piece 100 to be tested, one end of the probe assembly 5 is used for being connected with a wiring terminal on the lamp piece, and the other end of the probe assembly 5 is connected to external equipment to conduct the lamp piece 100, so that the lamp piece 100 is detected.

Since the positions and distances of the connection terminals of different types of the lamp sheets 100 are different, in order to realize that the lamp sheet detection apparatus is suitable for various types of lamp sheets, the probe assembly 5 needs to be adjustable on the plane where the probe assembly 5 is located. In the present embodiment, the probe assembly 5 has a guide rail 4 slidably disposed on the support table 1 along an X direction and a probe assembly 5 slidably disposed on the guide rail 4 along a Y direction, the X direction being non-parallel to the Y direction.

The probe assembly 5 can be moved in both the Y direction and the X direction by the arrangement of the above structure, but not in parallel with the Y direction and the X direction. Thus, in theory, the probe assembly 5 can move arbitrarily in the plane of the probe assembly. The probe assembly 5 can be conveniently adjusted by the aid of the structure, so that the probe assembly is suitable for various lamp sheets, and the applicability of the device is improved.

In principle, the X direction and the Y direction are either two intersecting directions, and in this embodiment, for more convenient adjustment of the probe assembly 5, the X direction is a horizontal direction, the Y direction is a direction perpendicular to the X direction, and the Y direction may be a vertical direction perpendicular to a horizontal plane or an oblique direction oblique to the horizontal plane and perpendicular to the X direction. The X direction and the Y direction are set to be perpendicular to each other, so that the probe assembly 5 can be adjusted more conveniently and accurately.

Specifically, in the present embodiment, the probe mechanism is provided with two first probe mechanisms 2 and two second probe mechanisms 3, respectively, and the first probe mechanisms 2 and the second probe mechanisms 3 can slide on the support table 1 to move toward or away from each other to adjust the distance between the two mechanisms in the X direction. The adjustment of the probe assembly 5 can be conveniently achieved by adjusting both probe mechanisms simultaneously. Of course, in other embodiments, only the first probe mechanism 2 or the second probe mechanism 3 may be adjusted to achieve adjustment of the distance between the two.

The first probe mechanism 2 and the second probe mechanism 3 have a similar structure in the present embodiment, and the first probe mechanism 2 is exemplified to be deployed here. The first probe mechanism 2 comprises a slide rail 4, the slide rail 4 is provided with a slide block 41 which is in sliding fit with the support table 1 and slides along the X direction, and a support plate 42 fixed on the slide block 41, the support frame 42 extends along the Y direction, and the probe assembly 5 is arranged on the support plate 42 in a sliding manner.

As shown in fig. 6 and 9, a first slide groove 10 adapted to the slide block 41 is provided on the support table 1, and an extending direction of the first slide groove 10 extends in the X direction, that is, the first slide groove 10 extends in the horizontal direction. To better ensure that the slider 41 slides within the first sliding slot 10, the first sliding slot 10 is retracted at the notch position to avoid the slider 41 slipping off the notch position.

In order to more conveniently control the sliding of the sliding block 41 in the first sliding slot 10, the light sheet detecting device in this embodiment further has a driving component for controlling the movement of the sliding block 41, and the driving component drives the sliding block 41 to control the movement of the guide rail 4.

Specifically, as shown in fig. 7 to 9, the driving assembly includes a rack 411 disposed at one end of the slider 41 close to the supporting platform 1 and a driving gear 7 disposed on the supporting platform 1, the driving gear 7 is engaged with the rack 411, and the driving gear 7 is rotated to drive the guide rail 4 to move along the X direction.

The driving gear 7 may be a circular gear rotatably mounted on the supporting platform 1, a mounting groove 11 is provided on the supporting platform 1, the mounting groove 11 is communicated with the first sliding chute 1, and the position of the mounting groove 11 is opposite to the position of the rack 411. The driving gear 7 is rotatably installed in the installation groove 11. The rack 411 and the slide block 41 are driven to move by rotating the driving gear 7 so as to control the movement of the guide rail 4. The movement of the control slider 41 can be adjusted more finely by the arrangement of the drive gear 7. In another embodiment, the driving gear 7 may also be a worm provided on the supporting platform 1, and the slider 411 is provided with a helical rack adapted to the worm.

In the embodiment, the guide rails 4 on the first probe mechanism 2 and the second probe mechanism 3 are respectively provided with a separate driving component for controlling the movement of the guide rails, so that the position between the two probe mechanisms can be adjusted more flexibly. Of course, in another embodiment, the two guide rails 4 can be moved simultaneously by one drive assembly, but when the two guide rails 4 are controlled by one drive assembly, only the two guide rails can be moved closer to each other or away from each other simultaneously.

Further, as shown in fig. 4 to 6, in order to facilitate more precise control of the movement of the guide rail 4, a second scale 12 is further disposed on the support table 1, and the second scale 12 extends in the X direction. A second pointer 412 adapted to the second scale 12 is disposed on the guide rail 4. The position of the indication rail 4 on the support table 1 is realized by the cooperation of the second indication needle 412 and the second scale 12.

In this embodiment, the second pointer 433 is fixed to the slider 41, and a pointer chute fixedly fitted to the second pointer 412 is provided on the support table 1, and the pointer chute extends in the X direction. The first end of the second pointer 412 is fixed on the slider 41, and the second end of the second pointer 412 penetrates through the pointer chute and extends outwards to the position of the second scale 12.

As shown in fig. 4 to 7, the guide rail 4 has a metal via 424 extending in the Y direction. The metal via strip 424 is electrically connected to an external device, and the probe assembly 5 is electrically connected to the metal via strip 424. The probe assembly 5 is electrically connected to an external device through a metal via 424. The probe assembly 5 is in contact with the metal via 424 at all times during the sliding process.

The guide rail 4 is provided with a mechanism sliding groove 422 in sliding fit with the probe assembly 5, and the mechanism sliding groove 422 extends along the Y direction. The metal via 424 is exposed toward the mechanism chute 422. In this embodiment, the metal via strip 424 is actually disposed on the inner side wall of the mechanism sliding groove 422, and such a structure prevents the metal via strip 424 from being exposed, i.e., away from the position touched by the person, thereby preventing the risk of electric shock of the operator, and improving the safety of the detection device.

As shown in fig. 10-11, the probe assembly 5 has a probe base 53 and a probe head 54 slidably engaged with the mechanism slide channel 422. The probe base 53 is provided with a metal contact 51 which is in butt fit with the metal conducting strip 424, and the metal contact 51 is electrically connected with the probe head 54. One end of the metal contact 51 facing the metal via strip 424 is a spherical end, and the spherical end can conveniently slide with the metal via strip 424. The arrangement of the above structure can realize the electrical connection of the metal via strip 424 while ensuring the smooth sliding of the metal contact 51 and the metal via strip 424.

Further, in order to better achieve the connection contact between the metal contacts 51 and the metal via strips 424, in this embodiment, the probe head 54 is disposed on the side of the probe base 53 away from the mechanism sliding groove 422, and the metal contacts 51 are disposed on the side of the probe base 53 away from the mounting surface of the probe head 54. Accordingly, the metal via bar 424 is disposed at the bottom of the mechanism chute 422. The abutting force generated by the lamp slice after the probe head 54 and the lamp slice are contacted can act on the metal contact 51 through the probe base 53, so that the metal contact 51 abuts on the metal conducting strip 424, and the contact stability of the metal contact 51 and the metal conducting strip 424 is further ensured.

A conduction bar mounting groove for mounting and fixing the metal conduction bar 424 is arranged at the bottom of the mechanism sliding groove 422, and the metal conduction bar 424 is fixed in the conduction bar mounting groove. In this embodiment, two metal contacts 51 are disposed on the probe base 53, the two metal contacts 51 are symmetrically disposed on the probe base 53, two corresponding metal conducting bars 424 are also disposed, and the two metal conducting bars 424 are symmetrically disposed in the mechanism sliding groove 422.

Further, the probe assembly 5 further includes a metal spring 52, and the probe head 54 is elastically connected to the metal contact 51 through the metal spring 52. The probe base 53 is provided with a mounting hole 50 for accommodating the metal spring 52, and the probe head 54 is movably arranged in the mounting hole 50 and protrudes to the outer side surface of the probe base 53 under the action of the metal spring 52. The probe tip compresses the metal spring 52 when the light sheet is pressed against the probe tip 54. The connection contact of the probe tip 54 with the connection terminals of the lamp chip is more flexibly stabilized by the metal spring 52.

It will be appreciated that the support 4 also has a stop mechanism 43 for limiting the position of the probe assembly 5 on the support plate 42, as shown in figure 5. The limiting mechanism 43 is provided with a stop block 431 and a bolt body 432 which penetrates through the stop block 431 and is in threaded connection with the probe assembly 5; the supporting plate 42 is provided with a limiting mechanism sliding groove 420 which extends along the Y direction and is in clearance fit with the bolt body 432, and the bolt body 432 can slide up and down along the limiting mechanism sliding groove 420; the stopper 431 and the probe assembly 5 are respectively disposed at both sides of the supporting plate 42.

When the probe assembly 5 needs to be locked, the bolt body 432 is screwed forward in the direction of the probe base 5 by screwing the bolt body 432 so as to be fixed on the probe base 53, so that the two ends of the probe assembly 5 and the stop block 431 are respectively pressed and attached on the supporting plate 42 to realize the locking and fixing of the probe assembly 5. When the probe assembly 5 is required to slide, the clamping effect of the probe assembly 5 and the stop block 431 on the support plate 42 is reduced by unscrewing the bolt body 432, and thus the adjustment of the probe assembly 5 in the Y direction can be realized.

In this embodiment, the supporting plate 42 has a stopper slide groove 423 slidably engaged with the stopper 431, the stopper slide groove 423 and the mechanism slide groove 422 are oppositely disposed at the front and rear sides of the supporting plate 42, and the mechanism slide groove 422 and the stopper slide groove 423 are communicated through a limiting mechanism slide groove 420. The stopper 431 can be restricted by the stopper slide groove 423, so that the stopper 431 is prevented from rotating along the circumferential direction of the bolt body 432.

Further, as shown in fig. 8, in order to control the position of the probe assembly 5 in the Y direction more accurately, a first scale 421 arranged along the Y direction is provided on the guide rail 4; a first pointer 433 matched with the first scale 421 is fixedly connected to the probe assembly 5. The specific position of the control probe assembly 5 can be determined more precisely by the cooperation of the first scale 421 and the first pointer 433.

The two terminals of the lamp strip 100 are generally disposed on the same horizontal plane, which requires the probe assemblies 5 of the first probe mechanism 2 and the second probe mechanism 3 to be located at the same height, and the probe assemblies located on the two probe mechanisms can be conveniently adjusted to be located at the same height through the cooperation of the first scale 421 and the first pointer 433.

Specifically, in this embodiment, the first scale 421 is disposed on the side of the supporting plate 42 opposite to the sliding surface of the probe assembly 5, and the first pointer 433 is disposed on the stop block 431. The probe assembly 5 is arranged on the opposite side of the sliding surface, so that the probe assembly 5 can be conveniently adjusted. Because there is the sheltering from of lamp piece 100 in the testing process on probe subassembly 5 slip plane one side, therefore inconvenient to probe subassembly 5 regulation, and set up first scale 421 in the one side that deviates from the slip plane and then avoided the appearance of above-mentioned condition.

Further, as shown in fig. 3, the supporting table 1 has a positioning member 15 for defining the position of the object to be measured. The retainer 15 has a first positioning portion 151 for abutting against the rear side surface of the positioning piece 100 and a second positioning portion 152 for abutting against the left side surface or the right side surface of the positioning piece 100.

As shown in fig. 1-3, the light sheet detection device further has a base 8; the supporting table 1 is rotatably arranged on the base 8 through an angle adjusting mechanism. The angle adjustment mechanism can swing the support table 1 in the front and rear directions, and thus the placement position of the lamp sheet 100 placed on the support table 1 can be adjusted to be suitable for detection of lamp sheets in various states. In this embodiment, the supporting platform 1 has a supporting surface 16 for supporting the bottom of the lamp sheet 100, and the supporting surface 16 intersects with the plane of the base 8; the angle adjusting mechanism is used for adjusting the intersecting angle of the supporting surface 16 and the plane of the base 8.
