The screw locking process is to lock the screws on the copper pillars to assemble the light board and the bottom shell.

[0003] In the related art, the LED module is generally supported and fixed by means of a screw locking fixture, and then the screws are locked manually or by machine. However, the labor efficiency is low and the labor cost is high; when the machine is locked, the locking quality is unstable and the screw locking deviation problem still occurs, which is not suitable for mass production. It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present disclosure, and therefore may include information that does not constitute prior art known to ordinary technicians in the field. Utility Model Content

[0004] The purpose of the present disclosure is to provide an LED module locking fixture to overcome the problems of low efficiency and locking deviation when screws are locked on the LED module in the related art.

[0005] Other features and advantages of the present disclosure will become apparent from the following detailed description, or may be learned in part by the practice of the present disclosure.

[0006] According to one aspect of the present disclosure, there is provided a LED module locking fixture for screw locking of LED modules, the locking fixture comprising a main body, a pressure plate and a plurality of guide pillars. The main body is provided with a receiving groove, the receiving groove is used to accommodate the LED module; the pressure plate is arranged above the main body, the pressure plate is provided with a plurality of positioning holes, the size of the positioning holes is adapted to the size of the screws; a plurality of guide pillars are arranged on the main body, the pressure plate is movably connected to the plurality of guide pillars, the pressure plate can translate along the plurality of guide pillars; wherein the pressure plate comprises a clamping state, in which the pressure plate can press against the copper pillars of the LED module, the positioning holes correspond to the positions of the copper pillars of the LED module.

[0007] During the screw locking process, the LED module is placed in the receiving groove of the main body. When the pressure plate is in a pressed state, the pressure plate presses against the copper column of the LED module to ensure the stability of the LED module during the locking process of the locking device, realize batch locking or automatic locking, and improve work efficiency. At the same time, the positioning perforations are set to correspond to the positions of the copper columns. The locking device locks the screws on the copper columns through the positioning perforations. The positioning effect of the positioning perforations on the screws can avoid screw locking deviation.

[0008] In one embodiment of the present disclosure, the locking fixture includes a limiting assembly arranged on both sides of the main body, and the pressure plate includes a yielding state. In the yielding state, the limiting assembly can limit the pressure plate; in the clamping state, the limiting assembly does not limit the pressure plate.

[0009] Through the limit assembly set on the main body, in the yielding state, the limit assembly can limit the pressure plate at a higher position, which is convenient for placing the LED module. In the pressing state, the limit assembly does not limit the pressure plate, and the pressure plate moves downward to press the copper column of the LED module. The limit assembly is used to switch the pressure plate between the yielding state and the pressing state.

[0010] In one embodiment of the present disclosure, the limiting assembly includes a rotating block and a rotating rod, the rotating block is sleeved on the rotating rod, and in a yielding state, the rotating block rotates to below the pressure plate, and the rotating block supports the pressure plate.

[0011] By sleeve-arranging the rotating block on the rotating rod, the rotating block can rotate to change its position. When it rotates to the bottom of the pressure plate, it can support the pressure plate. On the contrary, when the rotating block rotates away from the bottom of the pressure plate, the rotating block avoids the pressure plate, and the pressure plate can move downward to press the LED module. Through the selective movement of the rotating block, the matching relationship between the rotating block and the pressure plate can be changed, and the two states of the pressure plate can be realized, which has the advantage of convenient operation.

[0012] In one embodiment of the present disclosure, the limiting assembly includes a support plate and an elastic member, the support plate is arranged on the main body, the elastic member is arranged on the upper part of the support plate, the elastic member can be extended and retracted relative to the pressure plate, and a slot is provided on the pressure plate. When in the yielding state, the elastic member cooperates with the slot.

[0013] The elastic member can be extended and retracted relative to the pressure plate. When the pressure plate moves upward to the position where the elastic member corresponds to the slot, the elastic member extends and engages in the slot, so that the pressure plate can be supported and the pressure plate is in a yielding state. When the pressure plate moves downward to the state of leaving the yielding state, the elastic member is squeezed by the slot and retracts, so that the pressure plate can move downward to press against the LED module, and the pressure plate is in a compressed state. By extending and retracting the elastic member, the matching relationship between the elastic member and the slot can be changed, and two states of the pressure plate can be realized, which has the advantages of optimized structure and convenient operation.

[0014] In one embodiment of the present disclosure, the elastic member is a positioning bead.

[0015] The elastic member is a positioning bead. As a component that can provide pressure and accurate positioning, the positioning bead can better cooperate with the card slot and position the pressure plate on the upper part of the support plate when in the yielding state.

[0016] In one embodiment of the present disclosure, a plurality of recessed portions are provided on the edge of the pressing plate.

[0017] In the pressed state, the LED module is placed in the receiving groove with the lamp surface facing downward, and the pressing plate is pressed against the copper column of the LED module. By providing the recessed portion, the weight of the pressing plate can be reduced, thereby reducing the pressure on the lamp surface of the LED module.

[0018] In one embodiment of the present disclosure, an avoidance hole is opened on the pressing plate, and the avoidance hole can be used to avoid the electronic components of the LED module.

[0019] By providing the avoidance holes, the electronic components of the LED module are avoided, so as to prevent the electronic components from obstructing the pressing plate from moving downward along the guide pillars to a pressed state, and also to prevent the electronic components from being crushed by the pressing plate.

[0020] In one embodiment of the present disclosure, the pressure plate includes a main body and a plurality of protective rings embedded in the main body, the positioning holes are arranged in the protective rings, and the hardness of the protective rings is greater than the hardness of the main body.

[0021] By embedding a protective ring on the body of the pressure plate, the hardness of the protective ring is greater than the hardness of the body. When in a compressed state, the protective ring contacts the copper column and the screw, avoiding friction between the body and the copper column and the screw, thereby increasing the service life of the body.

[0022] In one embodiment of the present disclosure, a protrusion is provided on the top of the guide column, and a slide groove is provided on the pressure plate. When the slide groove cooperates with the guide column, the protrusion limits the upward translation of the pressure plate.

[0023] The pressing plate can be moved up and down along the guide post by arranging a slide groove on the pressing plate. Meanwhile, the convex part arranged at the top of the guide post limits the upward translation of the pressing plate, so as to prevent the pressing plate from sliding out from the top of the guide post.

[0024] In one embodiment of the present disclosure, an elastic pad is disposed in the receiving groove, and the shape of the elastic pad is adapted to the shape of the bottom wall of the receiving groove.

[0025] By matching the shape of the elastic pad with the shape of the bottom wall of the accommodating groove, the elastic pad can play a role of buffering and shock absorption on the lamp surface of the LED module, thereby protecting the lamp surface of the LED module.

[0037] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that the disclosure will be more comprehensive and complete and to fully convey the concepts of the example embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0038] The LED module can be an LED soft module, which includes a flexible light board made of a flexible insulating substrate and a rubber bottom shell. The light board has a light surface and an IC surface. The light surface is a certain number of LED lamp beads arranged together in a regular pattern and then packaged. A certain number of electronic components and copper pillars are arranged on the IC surface. The light board and the bottom shell are assembled by screwing them on the copper pillars. Using an LED module locking fixture to screw in can ensure the stability of the LED module during the locking process of the locking device, realize batch locking or automatic locking, improve work efficiency, and avoid screw locking deviation.

[0039] refer to Figure 1 and Figure 3 , Figure 1 and Figure 3 A LED module locking fixture that can embody the principles of the present disclosure is representatively shown, which is used for screw locking of LED modules, and includes a main body 10, a pressing plate 20, and a plurality of guide pillars 30. The pressing plate 20 includes a clamping state, in which the pressing plate 20 can press against the copper pillar of the LED module, and the positioning through-hole 21 corresponds to the position of the copper pillar of the LED module.

[0040] The main body 10 is provided with a receiving groove 11 for receiving the LED module. The pressing plate 20 is arranged above the main body 10, and the pressing plate 20 is provided with a plurality of positioning holes 21, the size of which matches the size of the screw. A plurality of guide posts 30 are arranged on the main body 10, and the pressing plate 20 is movably connected to the plurality of guide posts 30, and the pressing plate 20 can translate along the plurality of guide posts 30.

[0041] During the screw locking process, the LED module is placed in the receiving groove 11 of the main body 10. When the pressing plate 20 is in a pressed state, the pressing plate 20 presses against the copper column of the LED module to ensure the stability of the LED module during the locking process of the locking device, realize batch locking or automatic locking, and improve the working efficiency. At the same time, the positioning perforation 21 is set to correspond to the position of the copper column. The locking device locks the screw on the copper column through the positioning perforation 21. The positioning effect of the positioning perforation 21 on the screw can avoid the deviation of the screw locking.

[0042] refer to Figure 2 and Figure 5 The main body 10 can be rectangular and made of aluminum. A receiving groove 11 is provided on the upper surface of the main body 10, and the shape of the receiving groove 11 is adapted to the shape of the LED module.

[0044] By matching the shape of the elastic pad 12 with the shape of the bottom wall of the accommodating groove 11 , the elastic pad 12 can play a role in buffering and shock absorption for the lamp surface of the LED module, thereby protecting the lamp surface of the LED module.

[0045] refer to Figure 2 and Figure 5 The pressing plate 20 can be rectangular and made of aluminum. Four recessed portions 22 are provided on the four edges of the pressing plate 20, and the recessed portions 22 are recessed from the edges into the pressing plate 20. In the pressed state, the lamp surface of the LED module is placed downward in the receiving groove 11, and the pressing plate 20 is pressed against the copper column of the LED module. The weight of the aluminum pressing plate 20 is reduced by the recessed portions 22, thereby reducing the pressure on the lamp surface of the LED module.

[0046] The cross section of the recessed portion 22 can be an isosceles trapezoid. The recessed portions 22 on the two opposite edges of the pressing plate 20 are symmetrical, so that the center of gravity of the pressing plate 20 is located at the center of the pressing plate 20. When the pressing plate 20 moves up and down along the guide column 30, the pressing plate 20 can move relatively smoothly.

[0047] Although in the above embodiment, four recessed portions 22 are provided on the four edges of the pressing plate 20, the present disclosure is not limited thereto, for example, recessed portions 22 may be provided on one, two or three edges of the pressing plate 20, which may also achieve the effect of reducing the weight of the pressing plate 20.

[0048] refer to Figure 2 and Figure 5 Two avoidance holes 23 may be provided on the pressing plate 20, and the two avoidance holes 23 are arranged in the middle part of the pressing plate 20. The avoidance holes 23 are used to avoid the electronic components of the LED module, so as to prevent the electronic components from hindering the pressing plate 20 from moving downward along the guide pillars 30 to the compacted state, and also to prevent the electronic components from being crushed by the pressing plate 20.

[0049] The pressing plate 20 may include a main body 24 of the pressing plate 20 and a plurality of protective rings 25 embedded in the main body 24 . The positioning through holes 21 are disposed in the protective rings 25 . The hardness of the protective rings 25 is greater than that of the main body 24 .

[0050] Among them, the body 24 of the pressure plate 20 is made of aluminum, and the protection ring 25 can be made of copper, iron, stainless steel and other materials. There can be 18 protection rings 25, which are distributed around the two avoidance holes 23. In the clamped state, the bottom of the protection ring 25 can press against the copper column of the LED module, and a screw is placed in the positioning perforation 21 in the protection ring 25, and the screw is locked on the copper column by an electric screwdriver. In the clamped state, the protection ring 25 contacts the copper column and the screw, avoiding friction between the body 24 and the copper column and the screw, which can increase the service life of the body 24.

[0051] refer to Figure 1 , Figure 2 , Figure 3 and Figure 5 , four guide posts 30 can be arranged on the main body 10, and the four guide posts 30 are respectively located at the four corners of the main body 10. The guide posts 30 and the main body 10 can be fixedly connected by screws to enhance the stability of the guide posts 30. The guide posts 30 are perpendicular to the main body 10 and the pressing plate 20, and four slide grooves 26 are correspondingly provided at the four corners of the pressing plate 20. Through the cooperation of the slide grooves 26 and the guide posts 30, the pressing plate 20 can be translated up and down along the guide posts 30, so that the pressing plate 20 can move away from and close to the main body 10.

[0052] A protrusion 31 is provided at the top of the guide post 30. The cross-sections of the guide post 30 and the protrusion 31 may be circular, wherein the cross-sectional area of ​​the protrusion 31 is larger than the cross-sectional area of ​​the guide post 30. The protrusion 31 limits the upward translation of the pressing plate 20. When the pressing plate 20 moves upward along the guide post 30, the protrusion 31 can prevent the pressing plate 20 from sliding out of the top of the guide post 30.

[0053] refer to Figure 2 , Figure 4 and Figure 5 The locking fixture includes a limiting assembly 40 arranged on both sides of the main body 10, and the pressure plate 20 includes a yielding state and a pressing state. In the yielding state, the limiting assembly 40 can limit the pressure plate 20; in the pressing state, the limiting assembly 40 does not limit the pressure plate 20.

[0054] By means of the limiting assembly 40 provided on the main body 10, in the yielding state, the limiting assembly 40 can limit the pressing plate 20 at a higher position, so as to facilitate the placement of the LED module. In the pressing state, the limiting assembly 40 does not limit the pressing plate 20, and the pressing plate 20 moves downward to press the copper column of the LED module. The switching between the yielding state and the pressing state of the pressing plate 20 is realized by the limiting assembly 40.

[0055] refer to Figure 2 The limiting assembly 40 includes a rotating block 41 and a rotating rod 42 . The rotating block 41 is sleeved on the rotating rod 42 . When in the yielding state, the rotating block 41 rotates to the bottom of the pressing plate 20 , and the rotating block 41 supports the pressing plate 20 .

[0056] The rotating block 41 may have two ends, one high and one low. The high end can support the pressing plate 20, and the low end is provided with a hole. The rotating rod 42 passes through the hole and is fixedly connected to the main body 10. The rotating block 41 can rotate and change its position through the rotating rod 42. When it rotates to the bottom of the pressing plate 20, it can support the pressing plate 20. On the contrary, when the rotating block 41 rotates away from the bottom of the pressing plate 20, the rotating block 41 avoids the pressing plate 20, and the pressing plate 20 can move downward to press the LED module. Through the selective movement of the rotating block 41, the matching relationship between the rotating block 41 and the pressing plate 20 can be changed, and two states of the pressing plate 20 can be realized, which has the advantage of convenient operation.

[0057] When the LED module locking fixture is used, pull up the pressing plate 20 and move the rotating block 41 so that the rotating block 41 supports the pressing plate 20. Assemble the LED film in the receiving groove 11, with the IC facing up and the lamp facing down. Move the rotating block 41 again so that the rotating block 41 is not under the pressing plate 20, and then press the pressing plate 20 down to a tightened state. Place the screw in the positioning through hole 21 and lock the screw on the copper column with an electric screwdriver.

[0058] refer to Figure 4 and Figure 5 The limiting assembly 40 includes a support plate 43 and an elastic member 44. The support plate 43 is arranged on the main body 10. The elastic member 44 is arranged on the upper part of the support plate 43. The elastic member 44 can be extended and retracted relative to the pressing plate 20. The pressing plate 20 is provided with a slot 27. When in the yielding state, the elastic member 44 cooperates with the slot 27.

[0059] The bottom end of the support plate 43 is fixedly connected to the main body 10, and a through slot can be provided on the upper part of the support plate 43, in which the elastic member 44 is arranged. The elastic member 44 faces a side of the pressing plate 20, and a slot 27 is provided on the side, and the slot 27 can cooperate with the elastic member 44.

[0060] When the pressing plate 20 moves upward to the position where the elastic member 44 corresponds to the slot 27, the elastic member 44 extends out and is engaged in the slot 27, so that the pressing plate 20 can be supported, and the pressing plate 20 is in a yielding state. When the pressing plate 20 moves downward to the state of leaving the yielding state, the elastic member 44 is squeezed by the slot 27 and retracts, so that the pressing plate 20 can move downward to press against the LED module, and the pressing plate 20 is in a compressed state. By the expansion and contraction of the elastic member 44, the matching relationship between the elastic member 44 and the slot 27 can be changed, and two states of the pressing plate 20 can be realized, which has the advantages of optimized structure and convenient operation.

[0061] The elastic member 44 may be a positioning bead, which is also called a ball plunger or a spring plunger. The positioning bead may be composed of a housing 45, a spring 46 and a ball 47. The spring 46 with a certain pressure pushes the movement of the ball so that the device can run smoothly. As a component that can provide pressure and accurate positioning, the positioning bead can better cooperate with the card slot 27 of the pressure plate 20, and when in the yielding state, the pressure plate 20 is positioned on the upper part of the support plate 43.

[0062] When the LED module locking fixture is used, the pressing plate 20 is pulled up until the elastic member 44 is engaged with the card slot 27 of the pressing plate 20, so that the support plate 43 supports the pressing plate 20. The LED film is assembled in the receiving groove 11, wherein the IC surface faces upward and the lamp surface faces downward. Then a downward force is applied to the pressing plate 20, and the pressing plate 20 moves downward. The elastic member 44 retracts from the card slot 27 after receiving the downward force, and the pressing plate 20 continues to move downward to a clamped state. The screw is placed in the positioning through hole 21, and the screw is locked on the copper column by an electric screwdriver.
