[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0029] like Figure 1 and Figure 3 As shown, the present application provides a lamp bead testing fixture. An embodiment of the lamp bead testing fixture of the present application includes: a bracket 10 , an electrical connection seat 20 and a clamping seat 30 . Among them, the electrical connection seat 20 is arranged on the bracket 10, and the electrical connection seat 20 includes a seat body 21 and a conductive component 22 arranged on the seat body 21, and the conductive component 22 can be electrically connected to the soldering pad 101 on the lamp bead 1 to be tested; the clamping seat 30 can be raised and lowered on the bracket 10 and is located above the electrical connection seat 20, and the clamping seat 30 includes a seat body 31, a fixed clamping member 32 and a movable clamping member 33, the fixed clamping member 32 is fixedly connected to the bottom of the seat body 31 and has a first clamping surface 321, and the movable clamping member 33 is slidably arranged below the seat body 31 in a direction perpendicular to the first clamping surface 321 and has a second clamping surface 331, and the second clamping surface 331 is arranged opposite to the first clamping surface 321, and the first clamping surface 321 and the second clamping surface 331 can respectively cooperate with the two side wall surfaces of the lamp bead 1 to be tested that are arranged opposite to each other.

[0030] By applying the technical solution of this embodiment, the bracket 10 provides support for the electrical connection socket 20 and the clamping socket 30. The electrical connection socket 20 is arranged on the bracket 10 and can be electrically connected to the soldering pad 101 on the lamp bead 1 to be tested to supply power to the lamp bead 1 to be tested; the clamping socket 30 can be raised and lowered on the bracket 10 and is located above the electrical connection socket 20. During specific use, the staff can first raise the clamping socket 30 to a higher position to clamp and fix the lamp bead 1 to be tested, and then lower the clamping socket 30 that clamps the lamp bead 1 to be tested until the soldering pad 101 on the lamp bead 1 to be tested contacts the conductive component 22 of the electrical connection socket 20. The clamping seat 30 includes a seat body 31, a fixed clamping member 32 and a movable clamping member 33. The fixed clamping member 32 is fixedly arranged below the seat body 31, and the movable clamping member 33 is slidably arranged below the seat body 31. The first clamping surface 321 on the fixed clamping member 32 and the second clamping surface 331 on the movable clamping member 33 are arranged opposite to each other, and a clamping space is formed between the two to clamp the lamp bead 1 to be tested. Since the movable clamping member 33 is movably arranged on the seat body 31 in a direction perpendicular to the first clamping surface 321, the movable clamping member 33 can be away from or close to the fixed clamping member 32, and then the width of the clamping space between the first clamping surface 321 and the second clamping surface 331 is increased or decreased to adapt to the size of different models of lamp beads 1 to be tested, so as to realize the use of a lamp bead test fixture to test lamp beads 1 of various sizes. Therefore, the technical solution of this embodiment can effectively solve the problem of poor versatility of the bead test fixture in the related art.

[0031] like Figure 3 As shown, the fixed clamping member 32 also has a third clamping surface 322 arranged at an angle with the first clamping surface 321, and the third clamping surface 322 is located between the first clamping surface 321 and the second clamping surface 331. The first clamping surface 321 and the third clamping surface 322 can respectively abut against two side walls arranged adjacent to the lamp bead 1 to be tested. Among them, the first clamping surface 321 and the third clamping surface 322 can position the lamp bead 1 to be tested. After the positioning of the lamp bead 1 to be tested is completed, the position of the movable clamping member 33 is adjusted so that the second clamping surface 331 abuts against the side wall of the lamp bead 1 to be tested to fix the lamp bead 1 to be tested. Specifically, since the cross-section of the lamp bead 1 to be tested is generally a square structure, in this embodiment, the third clamping surface 322 is perpendicular to the first clamping surface 321.

[0032] like Figure 3As shown, in this embodiment, the seat body 31 and the fixed clamping member 32 are an integral structure, and the cross section of the fixed clamping member 32 is an "L"-shaped structure, and the two inner surfaces of the "L"-shaped structure respectively form a first clamping surface 321 and a third clamping surface 322. The movable clamping member 33 is movably arranged below the seat body 31 through a guide structure. Specifically, in this embodiment, the guide structure includes a guide groove arranged on the lower surface of the seat body 31 and a guide block arranged on the upper surface of the movable clamping member 33, the guide groove extends in a direction perpendicular to the first clamping surface 321, and the guide block is slidably arranged in the guide groove.

[0033] like Figure 1 and Figure 3 As shown, the movable clamping member 33 is guided and matched with the seat body 31, and the clamping seat 30 also includes a first adjustment knob 34 and a first adjustment screw. The first adjustment screw is located in the seat body 31 and is threadedly matched with the movable clamping member 33. The first adjustment knob 34 is connected to one end of the first adjustment screw and extends outward from the seat body 31. The first adjustment knob 34 can drive the first adjustment screw to rotate and then drive the movable clamping member 33 to move relative to the seat body 31. The rotation of the first adjustment screw is converted into the movement of the movable clamping member 33 through the threaded match between the first adjustment screw and the movable clamping member 33, which has the advantages of simple structure and easy adjustment. Specifically, the seat body 31 has a cavity inside, and the first adjustment screw and part of the structure of the movable clamping member 33 are located in the cavity. The part of the structure of the movable clamping member 33 is provided with a threaded hole, and the first adjustment screw is inserted into the threaded hole. The first adjusting knob 34 is disposed through the side wall of the cavity and extends out of the seat body 31 . The staff can drive the movable clamping member 33 to move to loosen or clamp the lamp bead 1 to be tested by turning the first adjusting knob 34 .

[0034] like Figure 1 and Figure 2 As shown, the conductive component 22 includes a support member 221 movably disposed on the base 21 and a conductive member 222 disposed above the support member 221. Specifically, the conductive member 222 is a copper column structure, and the conductive member 222 is penetrated through the support member 221. The support member 221 is movably disposed on the base 21 to drive the conductive member 222 to move, so as to adapt to the position of the pad 101 of the lamp bead 1 to be tested of different models.

[0035] like Figure 1 , Figure 2 and Figure 4As shown, the conductive component 22 also includes a second adjusting knob 223 and a second adjusting screw 224. The second adjusting screw 224 is located in the base 21 and is threadedly matched with the support member 221. The second adjusting knob 223 is connected to one end of the second adjusting screw 224 and extends outward from the base 21. The second adjusting knob 223 can drive the second adjusting screw 224 to rotate and then drive the support member 221 to move relative to the base 21 along the first direction a. Similarly, the base 21 also has a cavity inside, and part of the second adjusting screw 224 and the support member 221 are located in the cavity. The rotation of the second adjusting screw 224 is converted into the movement of the support member 221 along the first direction a through the threaded match between the second adjusting screw 224 and the support member 221, so as to adapt to the position of the soldering pad 101 of the lamp beads 1 to be tested of different models.

[0036] like Figure 1 , Figure 2 and Figure 4 As shown, the conductive component 22 also includes a third adjusting knob 225 and an adjusting gear 226. An adjusting rack 2211 meshing with the adjusting gear 226 is provided on the support member 221. The adjusting gear 226 is disposed in the base body 21. The third adjusting knob 225 is coaxially disposed with the adjusting gear 226 and extends outward from the base body 21. The third adjusting knob 225 can drive the adjusting gear 226 to rotate and thereby drive the support member 221 to move relative to the base body 21 along a second direction b, wherein the second direction b is perpendicular to the first direction a. The rotation of the adjusting gear 226 is converted into the movement of the support member 221 along the second direction b by the matching form of the gear rack. Since the adjusting gear 226 and the adjusting rack 2211 have a certain width in the first direction a, when the staff controls the support member 221 to move along the first direction a through the second adjusting knob 223, the adjusting gear 226 and the adjusting rack 2211 can always maintain a meshing state to ensure that the staff can also control the support member 221 to move along the second direction b through the third adjusting knob. The two sets of driving structures respectively realize the movement of the support member 221 along the first direction a and the second direction b, so that the support member 221 and the conductive member 222 penetrating the support member 221 can be moved to any position in the horizontal plane to adapt to the position of the soldering pad 101 of the lamp beads 1 to be tested of different models.

[0037] like Figure 4 As shown, the second adjustment knob 223 and the third adjustment knob 225 are arranged in parallel and both extend along the first direction a, and a slide groove extending along the second direction b is arranged on the base 21, and the second adjustment knob 223 is slidably arranged in the slide groove. When the support member 221 moves along the second direction b, the second adjustment screw 224 and the second adjustment knob 223 will follow the support member 221 to move along the second direction b, and the slide groove is arranged on the base 21 to avoid the second adjustment knob 223.

[0038] like Figures 1 to 4 As shown, the electrical connection seat 20 includes a plurality of conductive components 22, and the plurality of conductive components 22 are arranged one-to-one corresponding to the plurality of pads 101 of the lamp bead 1 to be tested, and the second adjustment knob 223 and the third adjustment knob 225 in each conductive component 22 are arranged adjacent to each other. Since the lamp bead 1 to be tested generally has a plurality of pads 101, for example, in the present embodiment, the lamp bead 1 to be tested has four pads 101, and correspondingly, the number of conductive components 22 is also four, and the arrangement of the four conductive components 22 corresponds to the arrangement of the four pads 101. Specifically, the four pads 101 are arranged in an array in the form of 2×2, and the four conductive members 222 of the four conductive components 22 are also arranged in the form of 2×2, so as to be respectively conductively connected to the four pads 101 one-to-one. The second adjustment knob 223 and the third adjustment knob 225 in each conductive component 22 are arranged together, so that the staff can adjust the position of the support member 221 in each conductive component 22.

[0039] Specifically, Figure 2 The second adjustment knob 223 and the third adjustment knob 225 shown in the figure are used to adjust the positions of the lowermost support member 221 and the conductive member 222. Figure 4 It is shown in Figure 2 The position adjustment principle diagram of the support member 221 and the conductive member 222 in FIG. 1 is as follows: Figure 4 It is only used to illustrate the adjustment principle. The shape of the support member 221 and the relative position relationship between the adjustment gear 226 and the second adjustment screw 224 are not limited to Figure 4 Preferably, as shown in Figure 1 and Figure 2 As shown, the second adjustment knob 223 and the third adjustment knob 225 are arranged on the same horizontal plane, so that the staff can adjust the position of the support member 221 conveniently through the second adjustment knob 223 and the third adjustment knob 225 .

The locking knob 40 includes a threaded rod passing through the side wall of the guide hole 351 and a knob structure arranged at the outer end of the threaded rod. When it is necessary to adjust the height of the clamping seat 30, the staff can loosen the locking knob 40 and then drive the clamping seat 30 to move along the guide vertical rod 12; when the position of the clamping seat 30 is adjusted, the staff can tighten the locking knob 40 so that the threaded rod presses against the guide vertical rod 12 to keep the clamping seat 30 in this position.

[0041] like Figure 1 and Figure 3 As shown, the seat body 31 is provided with a light-transmitting hole 311 extending in the up-down direction, and the light-transmitting hole 311 is provided corresponding to the first clamping surface 321. When the lamp bead 1 to be tested is clamped, the light-emitting surface of the lamp bead 1 to be tested faces upward, that is, toward the bottom surface of the seat body 31. The light-transmitting hole 311 is provided on the seat body 31 so that the light emitted by the lamp bead 1 to be tested after being powered on can be emitted outward through the light-transmitting hole 311, so as to test the brightness and wavelength of the lamp bead 1 to be tested.

[0042] like Figure 1 As shown, the electrical connection base 20 also includes a connector 23 disposed on the base body 21, and the connector 23 is electrically connected to the conductive component 22. The connector 23 is used to electrically connect to an external power supply and control component, and the connector 23 is electrically connected to the conductive component 222 through a conductive structure such as a wire to transmit electrical energy and control signals to the lamp bead 1 to be tested.
