Description

Technical Field

[0001] This utility model relates to the field of flexible circuit board technology for LED lamps, and in particular to an automatic bending detection fixture for flexible circuit boards with LED lamps. Background Technology

[0002] LED flexible circuit boards are flexible circuit boards used in LED lighting fixtures. They are characterized by their softness, bendability, and high flexibility. These circuit boards are mainly used to manufacture various LED light strips and other linear lighting products. When performing bending tests on this circuit board, it is necessary to place the circuit board inside a testing fixture.

[0003] Before inspecting the flexible circuit boards of LED lights, workers need to insert the circuit boards one by one into the circuit slots to limit the circuit boards to be inspected, and then bend the circuit boards one by one to achieve inspection. This process is time-consuming and reduces work efficiency. Therefore, it is necessary to propose an automatic inspection fixture for uniform bending, which can uniformly inspect the bending of circuit boards. Utility Model Content

[0004] The purpose of this utility model is to provide an automatic bending inspection fixture for flexible circuit boards with LED lights, in order to solve the problem mentioned in the background art that before inspecting the existing flexible circuit boards with LED lights, workers need to insert the circuit boards one by one into the circuit slots so that the circuit slots limit the circuit boards to be inspected, and then bend the circuit boards to be inspected one by one to achieve inspection. This process is time-consuming and reduces work efficiency.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is an automatic bending detection fixture for flexible circuit boards with LED lights, comprising:

[0007] The testing fixture assembly includes a placement plate, a set of circuit slots, and a circuit board; the circuit slots are all fixed to one side of the top of the placement plate, and one end of the circuit board is inserted into the circuit slot.

[0008] A bending assembly is provided, comprising a pressure rod, a set of plug-in plates, a connecting rod, a set of piston rods, a fixing plate, and a set of cylinders. The pressure rod is pressed above the middle of the circuit board, the plug-in plates are plugged into the other end of the circuit board, the connecting rods are fixed between the other ends of the plug-in plates, the piston rods are all fixed to the other end of the connecting rods, the fixing plate is fixed to the other side of the top of the placement plate, and the cylinders are all fixed to the outer end surface of the fixing plate.

[0009] Furthermore, the positions of the plug plate, piston rod, and cylinder are all corresponding, with one end of the piston rod passing through both sides of the fixed plate and slidably connected to the cylinder.

[0010] Vertical rods are fixedly connected to both sides of the top center of the placement plate. Vertical grooves are opened on the opposite end surfaces of the vertical rods. Electric sliders are slidably connected inside the vertical grooves. The electric sliders are fixedly connected to both ends of the pressure rod.

[0011] Furthermore, a guide rod is fixedly connected to one side of the vertical rod, and a fixing block is fixedly connected to the other end of the guide rod. The bottom end of the fixing block is fixedly connected to the top end of the placement plate.

[0012] A guide ring is slidably connected to the surface of the guide rod, and a docking rod is fixedly connected to the inner end of the guide ring. The other end of the docking rod is fixedly connected to both ends of the connecting rod.

[0013] Furthermore, it also includes auxiliary bending components;

[0014] The auxiliary bending assembly includes a fixed rod, a motor, a slot, and a lead screw; the fixed rod is fixed to the top of the connecting rod and corresponds to the position of the plug plate; the motor is fixed to the top of the fixed rod; the slot is opened inside one side of the fixed rod; and the lead screw is rotatably connected between the slot and the connecting rod.

[0015] Furthermore, the top end of the lead screw is fixedly connected to the output end of the motor, a connecting nut is slidably connected to the surface of the lead screw, and a connecting block is fixedly connected to the outer end surface of one side of the connecting nut.

[0016] Furthermore, a telescopic rod is fixedly connected to the outer end of the connecting block, and a push plate is fixedly connected to the output end of the telescopic rod.

[0017] Compared with existing technologies, the advantages of this utility model are:

[0018] I. This utility model, by setting up a pressure rod, a plug-in plate, a connecting rod, a piston rod, and a cylinder, allows the cylinder to drive the piston rod after each circuit board is plugged into the circuit slot. The piston rod then pushes the plug-in plate through the connecting rod, causing the plug-in plate to engage with the other end of the circuit board. At this time, the pressure rod presses down on the middle of the circuit board, and then the piston rod continues to move, pushing the circuit board through the plug-in plate. This causes the surface of the circuit board with LEDs to bend, thus enabling uniform bending detection of the circuit boards. This eliminates the need for workers to perform bending detection on each circuit board individually, reducing detection time and improving work efficiency.

[0019] Second, based on the first beneficial effect, a fixed rod with a vertical groove is set at the top of the connecting rod. A motor is fixedly connected to the top of the fixed rod. The motor drives the lead screw inside the vertical groove to rotate, causing the lead screw to move the connecting nut on the surface. At the same time, a telescopic rod is provided on the outer end of the connecting nut. When the circuit board is bent uniformly, the telescopic rod drives the push plate of the output rod to extend, so that the push plate presses the surface of the circuit board when it is bent, thereby causing the circuit board to bend a second time, thus enabling the circuit board to obtain a more comprehensive bending detection.

[0027] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0030] Please see Figures 1-3 As shown, this embodiment is an automatic bending detection fixture for flexible circuit boards with LED lights, comprising:

[0031] The testing fixture assembly includes a placement plate 11, a set of circuit slots 12 and a circuit board 13; the circuit slots 12 are all fixed to one side of the top of the placement plate 11, and one end of the circuit board 13 is inserted into the circuit slot 12.

[0032] The placement plate 11 is used to place the circuit slots 12 and the circuit board 13. The circuit slots 12 are used for inserting one end of the circuit board 13. There are six circuit slots 12 in total.

[0033] The bending assembly includes a pressure rod 21, a set of plug-in plates 22, a connecting rod 23, a set of piston rods 24, a fixing plate 25, and a set of cylinders 26. The pressure rod 21 is pressed above the middle of the circuit board 13, the plug-in plate 22 is plugged into the other end of the circuit board 13, the connecting rod 23 is fixed between the other ends of the plug-in plate 22, the piston rods 24 are all fixed to the other end of the connecting rods 23, the fixing plate 25 is fixed to the other side of the top of the placement plate 11, and the cylinders 26 are all fixed to the outer end surface of the fixing plate 25.

[0034] The pressure rod 21 is used to press the middle of the circuit board 13 to be tested. The plug-in plate 22 is used for plugging into the other end of the circuit board 13. The connecting rod 23 is used to connect all the plug-in plates 22. The piston rod 24 is used to push the connecting rod 23. The fixing plate 25 is used to connect the cylinder 26. The cylinder 26 is used to drive the piston rod 24.

[0035] The positions of the plug plate 22, piston rod 24 and cylinder 26 are all corresponding. One end of the piston rod 24 passes through both sides of the fixed plate 25 and is movably and slidably connected to the cylinder 26.

[0036] Vertical rods 27 are fixedly connected to the top center of the placement plate 11 on both sides of the edge. Vertical grooves 28 are opened on the opposite end surfaces of the vertical rods 27. Electric sliders 29 are slidably connected inside the vertical grooves 28. Electric sliders 29 are fixedly connected to the two ends of the pressure rod 21.

[0037] The number of plug-in plates 22, piston rods 24 and cylinders 26 are equal. Cylinders 26 drive piston rods 24, causing piston rods 24 to move and extend through fixed plates 25, thereby driving connecting rods 23 and plug-in plates 22 to move together. Vertical rods 27 are used to open vertical slots 28, which are used to move electric sliders 29. Electric sliders 29 are electrically connected to an external power source. Electric power drives electric sliders 29 to move up and down inside vertical slots 28, thereby driving pressure rods 21 to move.

[0038] A guide rod 291 is fixedly connected to one side of the vertical rod 27, and a fixing block 292 is fixedly connected to the other end of the guide rod 291. The bottom end of the fixing block 292 is fixedly connected to the top end of the placement plate 11.

[0039] A guide ring 293 is slidably connected to the surface of the guide rod 291. A mating rod 231 is fixedly connected to the inner end of the guide ring 293. The other end of the mating rod 231 is fixedly connected to both ends of the connecting rod 23.

[0040] The guide rod 291 is used for connecting and moving the guide ring 293, and the fixed block 292 is used for connecting the guide rod 291. When the cylinder 26 drives the piston rod 24, the piston rod 24 pushes the connecting rod 23, so that the connecting rod 23 drives the guide ring 293 to move on the guide rod 291 through the docking rod 231, so that the guide ring 293 and the guide rod 291 assist the connecting rod 23 to move, making the connecting rod 23 move more smoothly.

[0041] Working principle: In use, one end of the circuit board 13 is inserted into the circuit slot 12 one by one. At this time, the electric slider 29 is located above the inside of the vertical slot 28. Since the electric slider 29 is electrically connected to the external power supply, the electric power drives the electric slider 29 to move downward inside the vertical slot 28, causing the electric slider 29 to drive the pressure rod 21 to move, causing the pressure rod 21 to press the middle of the circuit board 13. Then the cylinder 26 is opened, and the cylinder 26 drives the piston rod 24, causing the piston rod 24 to push the connecting rod 23. At this time, the connecting rod 23 is driven by the docking rod 231. The guide ring 293 moves on the guide rod 291, causing the guide ring 293 and the guide rod 291 to move together with the auxiliary connecting rod 23, making the connecting rod 23 move more smoothly. At the same time, the piston rod 24 pushes the plug-in plate 22 through the connecting rod 23, so that the plug-in plate 22 is engaged with the other end of the circuit board 13. Then the piston rod 24 continues to move, causing the piston rod 24 to continue to push the circuit board 13 through the plug-in plate 22, causing the surface of the circuit board 13 with LEDs to bend, thereby uniformly performing bending detection on the circuit board 13.

[0042] The above steps, through the interaction between cylinder 26 and piston rod 24, can drive connecting rod 23 and plug plate 22 to move.

[0043] Please see Figures 1-4 As shown, this embodiment, based on embodiment 1 above, further includes:

[0044] Auxiliary bending components;

[0045] The auxiliary bending assembly includes a fixed rod 31, a motor 32, a slot 33, and a lead screw 34; the fixed rod 31 is fixed to the top of the connecting rod 23 and corresponds to the position of the plug plate 22; the motor 32 is fixed to the top of the fixed rod 31; the slot 33 is opened inside one side of the fixed rod 31; and the lead screw 34 is rotatably connected between the slot 33 and the connecting rod 23.

[0046] The fixing rod 31 is used to open the slot 33, the motor 32 is used to drive the lead screw 34 to rotate, the slot 33 is used to connect and rotate the lead screw 34, and the lead screw 34 is used to connect and move the connecting nut 35.

[0047] The top end of the lead screw 34 is fixedly connected to the output end of the motor 32. A connecting nut 35 is slidably connected to the surface of the lead screw 34. A connecting block 36 is fixedly connected to the outer end surface of one side of the connecting nut 35.

[0048] When the motor 32 starts, it can drive the lead screw 34 to rotate in the slot 33 through the output end, causing the lead screw 34 to drive the connecting nut 35 on its surface to move. The connecting block 36 is used to connect the telescopic rod 37. When the connecting nut 35 moves, the telescopic rod 37 can be driven to move together through the connecting block 36.

[0049] A telescopic rod 37 is fixedly connected to the outer end of the connecting block 36, and a push plate 38 is fixedly connected to the output end of the telescopic rod 37.

[0050] Telescopic rod 37 is electrically connected to an external power source. Electricity drives telescopic rod 37, causing its output end to move outward, which in turn causes the push plate 38 to move together.

[0051] Working principle: When the cylinder 26 pushes the circuit board 13 to bend uniformly through the piston rod 24 and the plug plate 22, the motor 32 starts. The motor 32 drives the lead screw 34 to rotate in the slot 33 through the output end, causing the lead screw 34 to move the connecting nut 35 on its surface. The connecting nut 35 drives the telescopic rod 37 to move together through the connecting block 36. When the connecting nut 35 moves to the appropriate position, the motor 32 stops. Then, since the telescopic rod 37 is electrically connected to the external power source, the telescopic rod 37 is electrically driven, causing the output end of the telescopic rod 37 to move outward. The output end of the telescopic rod 37 drives the push plate 38 to move together, so that the push plate 38 presses the surface of the circuit board 13 during bending, thereby causing the circuit board 13 to bend twice, thus enabling the circuit board 13 to obtain a more comprehensive bending detection.

[0052] The above steps can improve its functionality.
