Description

Technical Field

[0001] This invention relates to the field of wire cutting test equipment, and more particularly to an LED bulb wire cutting test equipment. Background Technology

[0002] LED bulbs are widely used in home lighting, commercial lighting and other fields due to their advantages such as energy saving, long life and environmental protection. In the production and manufacturing process of LED bulbs, the processing of the lamp cup circuit (wire cutting), electrical performance testing and lamp holder assembly are key processes to ensure product quality and reliability. The rationality of the process and the accuracy of operation directly affect the production efficiency, cost control and the factory qualification rate of the product.

[0003] Currently, the industry faces several technical challenges in the wire cutting, testing, and assembly processes for LED bulbs: Firstly, the testing procedures are poorly designed, leading to material waste and inconvenience in maintenance. Existing production processes often place the circuit testing step after the lamp head assembly, meaning the lamp head and lamp cup are fixed first, and then the finished product is tested for power-on or continuity. If open circuits or short circuits are found at this point, the assembled lamp head cannot be reused, resulting in significant material waste. Secondly, because the lamp head is already fixed, the subsequent disassembly and separation of the lamp head and lamp cup for defective products is complex, difficult to maintain, and time-consuming, further increasing production auxiliary costs. Summary of the Invention

[0004] The purpose of this invention is to address the problem that in existing production processes, the circuit testing step is often placed after the lamp head is assembled. That is, the lamp head and lamp cup are fixed first, and then the finished product is tested for power-on or continuity. If problems such as open circuit or short circuit are found at this time, the assembled lamp head cannot be reused, resulting in serious material waste. Therefore, this invention proposes an LED bulb wire cutting test device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An LED bulb wire-cutting test device includes a cabinet, on which a conveying mechanism for conveying the pre-assembled lamp cup is installed. The conveyor belt surface of the conveying mechanism is provided with a plurality of first receiving seats for placing the lamp cup. A lamp head assembly mechanism is installed on one side of the upper surface of the cabinet. A rear test unit is provided on one side of the lamp head assembly mechanism. A front test unit is installed on one side of the conveying mechanism. The pre-test unit includes a first rodless cylinder mounted on the cabinet via a first bracket. A first slide cylinder is mounted on the slider surface of the first rodless cylinder. The lamp cup conveyed to the front end by the conveying mechanism is disengaged from the first receiving seat by the front pneumatic gripper mounted on the slide surface of the first slide cylinder. The bottom of the slide of the first slide cylinder is equipped with a base, and the bottom of the base is equipped with an inlet pipe. The detector installed on the top of the inlet pipe is inserted into the line to realize the continuity test before the lamp head is installed. The bottom of the inner cavity of the inlet pipe is connected to a wire cutter. The wire cutter is connected to an adjustment component inserted into the bottom of the base to realize the fixed length cutting of the line after the test is qualified.

[0006] As a further description of the above technical solution: The detector includes a test rod inserted into a base. The test rod is connected to two probes, one end of which is inserted into the inlet pipe. The probe tips are hollow cylindrical. One end of the two probes is connected to a multimeter via a wire.

[0007] As a further description of the above technical solution: A wire guide seat is inserted into the top of the inner cavity of the inlet pipe. Both the wire guide seat and the wire cutter seat are inserted into the inlet pipe through a mounting shaft. The wire cutter seat and the wire guide seat are respectively connected to a lower inclined seat and an upper inclined seat through the shaft.

[0008] As a further description of the above technical solution: A return spring is sleeved on the surface of the shaft. The two ends of the lower return spring are respectively connected to the outer wall of the inlet tube and the inner side of the lower inclined seat, while the two ends of the upper return spring are respectively connected to the inner wall of the inlet tube and the outer wall of the guide seat.

[0009] As a further description of the above technical solution: The adjustment assembly includes a ring frame sleeved on the outer surface of the two inlet pipes. Multiple double-ended inclined rods are fixed on the inner wall of the ring frame, and the two ends of the double-ended inclined rods correspond to the inclined ends of the lower inclined seat and the upper inclined seat, respectively.

[0010] As a further description of the above technical solution: The bottom ends of the two inlet pipes are connected together by a fixing plate. A threaded rod is rotatably connected to the fixing plate. The ring frame is threaded onto the outer surface of the threaded rod. A micro motor with its output end connected to the top of the threaded rod is assembled in the middle of the upper surface of the base. A guide rod with one end inserted into the base is fixed on both sides of the ring frame.

[0011] As a further description of the above technical solution: A turntable is rotatably connected to the middle of the cabinet. Multiple second receiving seats are installed on the turntable to receive lamps that have passed the pre-test and have had their wires cut. A geared motor with its output end connected to the turntable is installed on the inner top wall of the cabinet.

[0012] As a further description of the above technical solution: The rear test unit includes a second rodless cylinder mounted on the cabinet via a second bracket. A second slide cylinder is mounted on the slider surface of the second rodless cylinder, and a test lamp holder is mounted on the slide surface of the second slide cylinder via a vertical plate.

[0013] As a further description of the above technical solution: A product receiving unit is mounted on the side of the cabinet surface near the rear test unit. The product receiving unit includes a third rodless cylinder mounted on the cabinet via a third bracket. A pneumatic push rod is mounted on the slider surface of the third rodless cylinder via a support base. One end of the pneumatic push rod is connected to a rear pneumatic gripper.

[0014] As a further description of the above technical solution: A support platform is installed on the outer wall of the cabinet. The surface of the support platform is provided with a defective product receiving box and a qualified product receiving box. A front defective product slide frame is provided on the side of the cabinet near the first bracket. A rear defective product slide frame and a qualified product slide frame are provided sequentially from front to back on the side of the cabinet near the third bracket.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: By setting up a pre-test unit, the testing process is optimized and material waste is reduced. The pre-test unit tests the lamp cup circuit before lamp head assembly. Defective products fall into the defective receiving box through the previous defective product slide frame and are directly rejected, avoiding defective lamp cups from flowing into the assembly process of the lamp head assembly mechanism. There is no need to waste lamp head materials. At the same time, defective products without lamp cups are easier to disassemble and repair later, reducing auxiliary costs. During the test, the wire guide is used to fix the wire in place to prevent the wire from shaking and causing poor contact, thus ensuring the reliability of the test results. During the wire cutting process, the adjustment component drives the threaded rod to rotate via a micro motor, which in turn drives the ring frame to move smoothly along the guide rod. The double-end inclined rod precisely pushes the lower inclined seat to drive the wire cutting seat to move. Combined with the fixing effect of the wire fixing seat, the wire that has passed the inspection is cut to a fixed length, ensuring the consistency of subsequent assembly.

[0016] Meanwhile, the post-testing unit can perform a second power-on test on the finished product after the lamp holder is assembled, eliminating unqualified products generated during the assembly process. The dual testing mechanism further ensures the product qualification rate before leaving the factory. Attached Figure Description

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0020] like Figure 1 - Figure 12 As shown, the present invention provides: An LED bulb wire-cutting test device includes a cabinet 10. A conveying mechanism 11 for conveying the pre-assembled lamp cup is installed on the cabinet 10. The conveyor belt surface of the conveying mechanism 11 is provided with multiple first receiving seats 12 for placing the lamp cup. In particular, the conveying mechanism 11 realizes the automated conveying of the pre-assembled lamp cup. The first receiving seats 12 are used to prevent the lamp cup from shifting or tipping over during the conveying process, ensuring that the lamp cup is accurately conveyed to the working position of the pre-test unit 30, thereby improving the conveying efficiency and positioning accuracy. A lamp head assembly mechanism 13 is installed on one side of the upper surface of the cabinet 10. In particular, the lamp head assembly mechanism 13 is a known technology, which is used to place the lamp head on the end of the lamp cup and then fix it. The specific structure and function are not described in detail here. like Figure 1 , Figure 2 and Figure 10 As shown, a pre-test unit 30 is installed on one side of the conveying mechanism 11; The pre-test unit 30 includes a first rodless cylinder 31 mounted on the cabinet 10 via a first bracket. A first slide cylinder 32 is mounted on the slider surface of the first rodless cylinder 31. The lamp cup conveyed to the front end by the conveying mechanism 11 is disengaged from the first receiving seat 12 by the front pneumatic gripper 33 mounted on the slide surface of the first slide cylinder 32. The bottom of the slide of the first slide cylinder 32 is equipped with a base 34, and the bottom of the base 34 is equipped with an inlet pipe 35. The detector 36 installed on the top of the inlet pipe 35 is inserted into the line and performs continuity detection before the lamp holder is installed. The bottom of the inner cavity of the inlet pipe 35 is connected to a wire cutter 37. The wire cutter 37 is connected to the bottom of the base 34 via an adjustment component 39 to cut the line to a fixed length after the detection is qualified. like Figure 1 and Figure 7As shown, a turntable 14 is rotatably connected to the middle of the cabinet 10. Multiple second receiving seats are installed on the turntable 14 to receive lamp cups that have passed the pre-test and have had their wires cut. A geared motor with its output end connected to the turntable 14 is installed on the inner top wall of the cabinet 10. Specifically, when a lamp cup that has passed the test by the detector 36 and has had its wire cut by the wire cutter 37 falls into the second receiving seat, the geared motor is started to drive the turntable 14 to rotate, so that the lamp cup is rotated to the lamp head assembly mechanism 13 area for lamp head installation. It should be noted that after each lamp cup completes a process, it must be rotated to the next area by the turntable 14.

[0021] like Figure 2 , Figure 6 and Figure 11 As shown, the detector 36 includes a test rod 361 inserted into the base 34. The test rod 361 is connected to two probes 362, one end of which is inserted into the inlet pipe 35. The probe heads of the probes 362 are hollow cylindrical. In particular, the hollow cylindrical meter head is adapted to the diameter of the wire core of the circuit. One end of the two probes 362 is connected to a multimeter through a wire. In particular, the multimeter is not shown in the figure. Specifically, in use, after the conveying mechanism 11 conveys the pre-assembled lamp cup to its front end (the end near the cabinet 10), the first rodless cylinder 31 is activated to drive the first slide cylinder 32 together with the front pneumatic gripper 33 to move above the lamp cup. At this time, the first slide cylinder 32 is activated again to control the front pneumatic gripper 33 to move downward until its gripper is on both sides of the lamp cup. Then, the front pneumatic gripper 33 is controlled to move downward so that the wire at the end of the lamp cup is inserted into the inlet pipe 35 until it is inserted into the hollow cylindrical meter head of the meter 362 and abuts against the top wall inside the meter head. At this time, the wire can be pre-tested before the wire is cut. When a problem is detected in the wire, it is placed in the unqualified area. Alternatively, the test lead 362 can be replaced with a terminal block, and the two terminals can be connected to a plug via a wire. The plug can then be connected to an external power source. It should be noted that the contact piece of the terminal block must be located on its inner top wall and be cylindrical. Using the above method, when the wire is inserted, the top of its core can be inside and wrapped by the cylindrical contact piece. At this time, the external power source can be turned on to perform a power-on test. Similarly, any unqualified products detected can be directly placed in the unqualified area.

[0022] A wire guide seat 38 is inserted into the top of the inner cavity of the inlet pipe 35. Both the wire guide seat 38 and the wire cutter seat 37 are inserted into the inlet pipe 35 via mounting shafts. The wire cutter seat 37 and the wire guide seat 38 are respectively connected to a lower inclined seat 310 and an upper inclined seat 311 via shafts. In particular, the lower inclined seat 310 and the upper inclined seat 311 have opposite inclination directions. In order to ensure the stability of the wire cutter seat 37 and the wire guide seat 38 during inward movement, an auxiliary rod is fixed to the top of the inner side of the lower inclined seat 310 and the upper inclined seat 311. One end of the auxiliary rod is inserted into the inlet pipe 35. A return spring is sleeved on the surface of the shaft. The two ends of the lower return spring are connected to the outer wall of the inlet tube 35 and the inner side of the lower inclined seat 310, respectively. The two ends of the upper return spring are connected to the inner wall of the inlet tube 35 and the outer wall of the guide seat 38, respectively.

[0023] like Figure 1 and Figure 7 As shown, in order to receive defective products, a product receiving unit 40 is installed on the side of the cabinet 10 near the rear test unit 20. The product receiving unit 40 includes a third rodless cylinder 41 mounted on the cabinet 10 via a third bracket. A pneumatic push rod 42 is mounted on the slider surface of the third rodless cylinder 41 via a support base. One end of the pneumatic push rod 42 is connected to a rear pneumatic gripper 43. A support platform is installed on the outer wall of the cabinet 10. The surface of the support platform is equipped with a defective product receiving box 44 and a qualified product receiving box 45. A front defective product slide frame 46 is located on the side of the cabinet 10 near the first bracket, and a rear defective product slide frame 47 and a qualified product slide frame 48 are located sequentially from front to back on the side of the cabinet 10 near the third bracket. Specifically, the outlet ends of the front defective product slide frame 46 and the rear defective product slide frame 47 correspond to the defective product receiving box 44, and the outlet end of the qualified product slide frame 48 corresponds to the qualified product receiving box 45. like Figure 1 , Figure 4 , Figure 5 , Figure 6 and Figure 12 As shown, the adjustment assembly 39 includes a ring frame 391 sleeved on the outer surface of the two inlet pipes 35. A plurality of double-ended inclined rods 392 are fixed on the inner wall of the ring frame 391. The two ends of the double-ended inclined rods 392 correspond to the inclined ends of the lower inclined seat 310 and the upper inclined seat 311, respectively. In particular, in the initial state, the double-ended inclined rods 392 are located in the middle position between the lower inclined seat 310 and the upper inclined seat 311, and their two ends are in contact with the top end of the lower inclined seat 310 and the bottom end of the upper inclined seat 311, respectively. In this state, there is no abutment between the lower inclined seat 310 and the upper inclined seat 311. Preferably, the bottom ends of two upper inclined seats 311 inside the inlet pipe 35 are fixed with connecting plates, and the bottom ends of the connecting plates are rotatably connected with inner plates. Both ends of the inner plates are rotatably connected to the connecting plates and are fitted with torsion springs. Under the action of the torsion spring, when the inner plates rotate inward under the action of external force, when the external force is released, the inner plates will rotate back to the vertical state. At the same time, the pushing force provided by the torsion spring to keep the inner plates in the state of the device is greater than the elastic force generated after the return spring is compressed. The top of the lower inclined plate 310 is fixed with an outer plate that fits against the inner plate. The outer side of the outer plate is on the same plane as the vertical section of the lower inclined plate, meaning it does not affect the movement of the double-ended inclined rod 392. In this state, when the upper inclined plate 311 moves inward, the lower inclined plate 310 does not move inward. However, when the inclined plate 310 moves inward, it will cause the upper inclined plate 311 connected to the inner plate to move together. In this state, when the upper inclined plate 311 moves to the point where the fixed wire seat 38 connected to it abuts against the outer wall of the wire harness, the wire harness is fixed. At this time, the cutter head of the wire cutter 37 also abuts against the outer wall of the wire harness. At this point, the lower inclined plate 310 continues to push the wire cutter 37 inward to cut the wire. As the lower inclined plate 310 continues to move inward, the upper inclined plate 311 can no longer move inward. At this point, its reaction force plus the elastic force after the return spring is compressed is greater than the force of the torsion spring. In this state, the outer plate will push the inner plate to rotate inward when it moves inward. However, it should be noted that in this process, no matter what angle the inner plate rotates inward, the outer plate is still outside the inner plate. After the cutting is completed, during the reset process of the lower inclined plate 310, the inner plate gradually returns to the vertical state under the action of the torsion spring. The bottom ends of the two inlet pipes 35 are connected together by a fixing plate. A threaded rod 393 is rotatably connected to the fixing plate. The ring frame 391 is threaded onto the outer surface of the threaded rod 393. A micro motor 394 with its output end connected to the top of the threaded rod 393 is assembled in the middle of the upper surface of the base 34. A guide rod 395 with one end inserted into the base 34 is fixed on both sides of the ring frame 391. Specifically, in actual use, the front pneumatic gripper 33 moves downward under the action of the first slide cylinder 32 until the hollow cylindrical meter head of the meter 362 is fitted onto the top of the circuit. The front pneumatic gripper 33 then grips the lamp cup. The front pneumatic gripper 33 moves upward through the first slide cylinder 32. During this process, the micro motor 394 is started to control the threaded rod 393 to rotate counterclockwise, thereby driving the ring frame 391 to move upward. During this process, the top inclined surface of the double-ended inclined rod 392 gradually abuts against the upper inclined seat 311 and the fixed line seat 38, moving inward, thereby fixing the circuit and ensuring stability during the test process of the detector 36. After the circuit is fixed, the continuity of the circuit is detected by the detector 36. When a problem is detected in the circuit, the first rodless cylinder 31 drives the first slide cylinder 32, together with the front pneumatic gripper 33, to move above the previous defective product slide frame 46. Then, the first slide cylinder 32 drives the front pneumatic gripper 33 to move the lamp cup downward to the bottom and contact the previous defective product slide frame 46. At this time, the front pneumatic gripper 33 is activated to release the defective lamp cup. The lamp cup falls into the defective product receiving box 44 through the previous defective product slide frame 46 for centralized collection. Through this detection, the lamp cup can be screened in advance and the defective product is directly rejected. There is no need to detect it after the lamp head is installed, which greatly saves the cost of the lamp head. Moreover, since the defective product is not installed with a lamp head, it is more convenient for subsequent disassembly and maintenance operations. When the circuit is detected to be normal, the first rodless cylinder 31 drives the first slide cylinder 32, together with the front pneumatic gripper 33, to move above the second receiving seat. During the movement, the micro motor 394 controls the threaded rod 393 to rotate clockwise, thereby driving the ring frame 391 to move downward. During the process, the top slope of the double-ended inclined rod 392 gradually releases its resistance to the upper inclined seat 311. During this process, the wire fixing seat 38 gradually moves outward and resets under the action of the reset spring. At the same time, as the ring frame 391 continues to move downward, the bottom slope of the double-ended inclined rod 392 gradually pushes against the lower inclined seat 310, thereby driving the wire cutting seat 37 to move inward. Thus, with the cooperation of the two wire cutting seats 37, the wire is cut, leaving only the length required for subsequent installation. After shearing, the first slide cylinder 32 drives the front pneumatic gripper 33 to move the lamp cup downward into the second receiving seat. At this time, the defective lamp cup is released by activating the front pneumatic gripper 33, and the lamp cup will fall completely into the second receiving seat.

[0024] like Figure 1 , Figure 7 and Figure 8 As shown, a rear test unit 20 is provided on one side of the lamp head assembly mechanism 13. The rear test unit 20 includes a second rodless cylinder 21 mounted on the cabinet 10 via a second bracket. A second slide cylinder 22 is mounted on the slider surface of the second rodless cylinder 21. A test lamp holder 23 is mounted on the slide surface of the second slide cylinder 22 via a vertical plate. Specifically, the lamp head is installed through the lamp head assembly mechanism 13. After the lamp head is installed, since the finished product is not absolutely qualified, it needs to be driven to rotate to the rear test unit 20. After rotating to the position, the second rodless cylinder 21 drives the second slide cylinder 22 together with the test lamp holder 23 to move above the product to be tested. At this time, the second slide cylinder 22 drives the test lamp holder 23 to move down to be fitted onto the lamp head. Then, the finished product is powered on and lit. If it can be lit normally, it is a qualified product; if it cannot be lit normally, it is a defective product. After the test, the lamp holder is reset, and the tested finished product is moved to the next area by rotating the turntable 14. When the tested finished product moves to the product receiving unit 40, the third rodless cylinder 41 drives the pneumatic push rod 42 together with the rear pneumatic gripper 43 to move above the finished product. Then, the pneumatic push rod 42 is activated to drive the rear pneumatic gripper 43 to move down and grab the finished product. After grabbing, the pneumatic gripper 43 moves up to make the finished product detach from the second receiving seat. At this time, if the finished product is qualified, the pneumatic gripper 43 is moved above the qualified product slide frame 48 by the third rodless cylinder 41, and then the pneumatic gripper 43 is driven by the pneumatic push rod 42 to move the qualified finished product downward to contact the qualified product slide frame 48. After contact, the finished product is released. At this time, the qualified finished product enters the qualified product receiving box 45 through the qualified product slide frame 48 for centralized collection. If the finished product is defective, it needs to be moved to the defective product slide frame 47 for release, so that it is concentrated in the defective product receiving box 44.
