Description

Technical Field

[0001] The invention relates to the technical field of lamp processing positioning fixtures, and in particular to a positioning fixture for processing and producing LED lamps. Background Art

[0002] The positioning fixtures used in the processing and production of LED lamps are the core equipment in the manufacturing of LED lamps. Their main function is to achieve accurate positioning and stable clamping of lamps, ensuring that the produced LED lamps have high precision and high quality. These fixtures are usually made of high-strength, wear-resistant and corrosion-resistant materials. Combined with precise positioning technology, they can accurately determine the position of lamps and provide precise benchmarks for subsequent processing.

[0003] After searching, a Chinese patent with a patent publication number of CN220073918U discloses a positioning fixture for processing LED lamps. Although the device can clamp the LED lamp by simultaneously gathering the clamping plates arranged around the LED lamp placement plate to ensure that the LED lamp is located at the center of the LED lamp placement plate, the processing positioning is accurate, and the positioning accuracy of the fixture is improved. However, since the surface of the LED lamp needs to be processed after being clamped, in order to ensure the accuracy and stability during processing, it is necessary to increase the force of the clamping plate to clamp the LED lamp. After the LED lamp is tightly clamped, the clamped part is easily damaged, which greatly affects the quality of the LED lamp and is not conducive to the production of LED lamps. Summary of the invention

[0004] The purpose of the present invention is to solve the disadvantage in the prior art that after the LED lamp is tightly clamped, the clamped part is easily damaged, and a positioning fixture for processing and producing LED lamps is proposed.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions: A positioning fixture for processing and producing LED lamps, comprising a bracket and a base, wherein a patch device is fixedly mounted on the top of the bracket, and the base is located directly below the patch device, and further comprising: A positioning plate, the positioning plate is fixedly mounted on the top of the base, and a positioning groove is provided in the middle of the top of the positioning plate, a lamp plate is placed in the positioning groove, and a mounting groove is provided in the middle of the top of the positioning groove, and a lamp base band is installed on the top of the lamp plate; A weak magnetic magnet is installed in the positioning groove. A plurality of groups of assembly holes are evenly penetrated around the center of the top of the lamp panel. A positioning rod is inserted into one group of the assembly holes. The bottom end of the positioning rod is adsorbed on the top of the weak magnetic magnet. The electromagnet is arranged in the installation groove, and two conductive wires are installed on the outside of the electromagnet. The lamp panel is arranged above the electromagnet. One end of the two conductive wires away from the electromagnet passes through the positioning plate and extends outward, and is connected to an external power supply.

[0006] Preferably, an adsorption plate is fixedly mounted on the top of the electromagnet to separate the electromagnet from the lamp panel.

[0007] Preferably, the weak magnetic magnet is ring-shaped.

[0008] Preferably, it also includes a pop-up mechanism, which includes four groups of through grooves, which are opened at the top of the positioning groove and evenly surround the installation groove. A spring is fixedly connected to the bottom wall of the through groove, and a protective plate is fixedly connected to the end of the spring away from the through groove, and the top of the protective plate abuts against the bottom end of the lamp panel.

[0009] Preferably, the protective plate is made of composite material.

[0010] Preferably, it also includes an auxiliary fixing mechanism, which includes four groups of equidistant electric push rods, which are fixedly installed on the outer side of the positioning plate, and the output ends of the electric push rods penetrate the side wall of the positioning plate and extend into the positioning groove, and the output ends of the electric push rods are fixedly connected to rubber push plates.

[0011] Preferably, one end of the rubber push plate facing the lamp panel is in contact with the outer side wall of the lamp panel, so as to enhance the connection stability between the rubber push plate and the lamp panel.

[0012] Preferably, the end of the rubber push plate that is in contact with the outer side wall of the lamp panel is arc-shaped.

[0013] Preferably, it also includes an air jet mechanism, which includes four groups of pressurizers, which are fixedly installed on the top of the positioning plate, and an air jet pipe is installed at the output end of the pressurizer, and the air outlet end of the air jet pipe faces the direction of the lamp panel.

[0014] Preferably, the four groups of pressurizers surround the positioning groove and are evenly distributed around the lamp panel.

[0015] Compared with the prior art, the advantages of the present invention are: 1. The present invention utilizes the weak magnetic property of the weak magnetic magnet so that the positioning rod can be easily moved on the weak magnetic magnet, thereby adapting to the positions of different assembly holes on different lamp panels. After the position of the positioning rod is determined, any assembly hole on the lamp panel is passed through the positioning rod to complete the basic positioning, and the conductive wire is energized by an external power supply, so that the electromagnet has an adsorption effect on the lamp panel, and the lamp panel is firmly fixed through the adsorption plate, so that the lamp panel can be fixed without physical contact with the lamp panel, thereby avoiding damage to the lamp panel. In addition, since the magnetic fields of the weak magnetic magnet and the electromagnet overlap with each other, and the electromagnet generates a strong electromagnetic field, the magnetic fields of the weak magnetic magnet and the electromagnet will interact with each other, enhance the attraction between each other, and generate a stronger magnetic field. This stronger magnetic field can make the positioning rod more firmly adsorbed on the surface of the weak magnetic magnet, thereby achieving a reinforcement effect.

[0016] 2. The present invention sets a pop-up mechanism and utilizes the gravity of the lamp panel and the adsorption force of the electromagnet to completely compress the spring into the through slot. The compressed spring prepares for the subsequent pop-up. When the current direction of the conductive wire is changed, the magnetic field direction of the electromagnet also changes accordingly, causing the electromagnet to repel the lamp panel. The spring will pop out from the through slot, and under the action of the repulsive force of the electromagnet and the rebound force of the spring, the lamp panel is lifted up by the protective plate. At this time, the edge height of the lamp panel is higher than the positioning slot, which is convenient for operators or machines to take the lamp panel.

[0017] 3. The present invention sets an auxiliary fixing mechanism and utilizes four sets of electric push rods to move the rubber push plate in the positioning groove toward the lamp panel, thereby pushing the lamp panel to make fine adjustments in position, ensuring that the center of the lamp panel coincides with the center of the adsorption plate, allowing the lamp panel to be adsorbed from the middle, thereby improving the adsorption effect of the lamp panel and thus improving the stability of the lamp panel when it is adsorbed and fixed.

[0018] 4. The present invention uses a jet mechanism to compress air using a pressurizer, and then ejects the compressed air from an air jet pipe, which can not only blow away dust on the LED lamp chip and improve its brightness and durability, but also because the four air jet pipes are symmetrically distributed around the lamp panel, the ejected gas forms an airflow thrust, which can prevent the lamp panel from moving during the patch process without contacting the lamp panel, thereby realizing the function of auxiliary positioning.

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0028] Reference Figure 1-7 A positioning fixture for processing and producing LED lamps includes a bracket 1 and a base 3. A patch device 2 is fixedly installed on the top of the bracket 1. The base 3 is located directly below the patch device 2, and a positioning plate 7 is fixedly installed on the top of the base 3. A positioning groove 8 is opened in the middle position of the top of the positioning plate 7. A lamp panel 4 is placed in the positioning groove 8. A lamp base band 6 is installed on the top of the lamp panel 4, and a plurality of assembly holes 5 are evenly penetrated around the center of the top of the lamp panel 4.

[0029] A weak magnetic magnet 11 is installed inside the positioning groove 8. The weak magnetic magnet 11 is annular. A positioning rod 12 is inserted into one of the multiple groups of assembly holes 5. The diameter of the positioning rod 12 is smaller than the diameter of the assembly holes 5 on the lamp panel 4, and the bottom end of the positioning rod 12 is adsorbed on the top of the weak magnetic magnet 11. Since the weak magnetic magnet 11 has weak magnetism, the positioning rod 12 can be easily moved on the weak magnetic magnet 11, so as to adapt to the positions of different assembly holes 5 on different lamp panels 4. After determining the position of the positioning rod 12, it passes through any assembly hole 5 on the lamp panel 4 to achieve a basic positioning effect. The appearance of the annular weak magnetic magnet 11 is more adapted to the appearance of the lamp panel 4, so that the lamp panel 4 can be better adsorbed and positioned by the positioning rod 12.

[0030] An installation groove 10 is opened at the middle position of the top of the positioning groove 8, and an electromagnet 17 is fixedly installed in the installation groove 10. Two conductive wires 18 are installed on the outside of the electromagnet 17, and an adsorption plate 19 is fixedly installed on the top of the electromagnet 17. A lamp panel 4 is placed on the top of the adsorption plate 19. The ends of the two conductive wires 18 away from the electromagnet 17 both extend outward through the positioning plate 7 and are connected to an external power supply. The conductive wires 18 are energized by the external power supply, so that the electromagnet 17 has an adsorption effect on the lamp panel 4, and the lamp panel 4 is firmly fixed through the adsorption plate 19 without direct contact with the electromagnet 17 to avoid excessive suction and damage to the lamp panel 4. At the same time, since the electromagnet 17 generates a strong electromagnetic field, the magnetic fields of the weak magnetic magnet 11 and the electromagnet 17 will interact with each other, thereby enhancing the attraction between them. This is because their magnetic fields overlap with each other, thus generating a stronger magnetic field. This stronger magnetic field allows the positioning rod 12 to be more firmly adsorbed on the surface of the weak magnetic magnet 11, thereby achieving a reinforcement effect. Four groups of through grooves 9 are evenly arranged at the top of the positioning groove 8 around the mounting groove 10. A spring 20 is fixedly connected to the bottom wall of the through groove 9. A protective plate 21 is fixedly connected to the end of the spring 20 away from the through groove 9. The top of the protective plate 21 abuts against the bottom end of the lamp panel 4, and the protective plate 21 is made of a composite material. Since the lamp panel 4 is placed in the positioning groove 8, the provision of the protective plate 21 can prevent the spring 20 from scratching the lower surface of the lamp panel 4. The composite material protective plate 21 is composed of a combination of multiple materials, combining the advantages of different materials, and has high strength and corrosion resistance. The corrosion-resistant characteristics prolong the service life of the protective plate 21, and the spring 20 in the through groove 9 is in a compressed state. The compressed spring 20 is prepared for the subsequent pop-up. When the current direction of the conductive wire 18 is changed, the magnetic field direction of the electromagnet 17 also changes accordingly, so that the electromagnet 17 repels the lamp panel 4, and the spring 20 pops out from the through groove 9. Under the action of the repulsive force of the electromagnet 17 and the rebound force of the spring 20, the lamp panel 4 is lifted up through the protective plate 21. At this time, the edge height of the lamp panel 4 is higher than the positioning groove 8, which is convenient for the operator or machine to take the lamp panel 4. In addition, the composite material is also lightweight, so that the protective plate 21 made of the composite material can lift the lamp panel 4 more quickly, thereby improving the efficiency of taking the lamp panel 4.

[0031] Four groups of equidistant electric push rods 15 are fixedly installed on the outer side of the positioning plate 7. The output end of the electric push rod 15 passes through the side wall of the positioning plate 7 and extends into the positioning groove 8. The output end of the electric push rod 15 is fixedly connected to a rubber push plate 16. The end of the rubber push plate 16 facing the lamp panel 4 is arc-shaped and fits with the outer wall of the lamp panel 4. By starting the four groups of electric push rods 15, the rubber push plate 16 in the positioning groove 8 is pushed forward, pushing the lamp panel 4 to make fine adjustments in position, ensuring that the center of the lamp panel 4 coincides with the center position of the adsorption plate 19, so that the lamp panel 4 is adsorbed from the middle, and the effect is better.

[0032] Four groups of pressurizers 13 are fixedly installed on the top of the positioning plate 7, which are wrapped around the positioning groove 8 and evenly distributed around the lamp panel 4. An air jet 14 is installed at the output end of the pressurizer 13, and the air outlet end of the air jet 14 is facing the lamp panel 4. The pressurizer 13 compresses the air and sprays the compressed air from the air jet 14, which can not only blow away the dust on the LED lamp chip and improve the brightness and durability; and because the four air jets 14 are symmetrically distributed around the lamp panel 4, the sprayed gas forms an airflow thrust, which can prevent the lamp panel 4 from moving during the patch process without contacting the lamp panel 4, thereby realizing the function of auxiliary positioning.

[0033] In the present invention, the LED lamp positioning fixture currently available on the market needs to clamp the lamp when in use, which may block the installation of the LED lamp core or damage the lamp tray 4. The present device not only does not require physical contact and fixation of the lamp tray 4 when installing the LED lamp chip, but also blows away the dust on the LED lamp core while achieving the fixing effect, thereby improving the brightness and durability, and after the processing is completed, the lamp tray 4 can be ejected from the positioning groove 8 for easy removal.

[0034] The weak magnetic magnet 11 is ring-shaped, and the positioning rod 12 on it can be adsorbed. Due to the weak magnetism, the positioning rod 12 can be easily moved on the weak magnetic magnet 11 to adapt to the positions of different assembly holes 5 on different lamp panels 4. The lamp panel 4 is placed in the positioning groove 8. The diameter of the positioning rod 12 is smaller than the diameter of the assembly hole 5 on the lamp panel 4. After the position of the positioning rod 12 is determined, it passes through any assembly hole 5 on the lamp panel 4 to achieve a basic positioning effect.

[0035] Simultaneously start the four electric push rods 15 to push the rubber push plate 16 in the positioning groove 8 forward, push the lamp panel 4 to make fine adjustments in position, ensure that the center of the lamp panel 4 coincides with the center of the adsorption plate 19, and allow the lamp panel 4 to be adsorbed from the middle for better effect.

[0036] The conductive wire 18 is energized, and the electromagnet 17 is in from the left and out from the right, so that the lamp panel 4 can be adsorbed by the electromagnet 17, and the lamp panel 4 is firmly fixed through the adsorption plate 19, and the lamp panel 4 is not in direct contact with the electromagnet 17 to avoid too strong suction and damage to the lamp panel 4. At the same time, since the electromagnet 17 generates a strong electromagnetic field, the weak magnetic magnet 11 and the magnetic field of the electromagnet 17 will interact with each other, thereby enhancing the attraction between them. This is because their magnetic fields overlap with each other, thereby generating a stronger magnetic field. This stronger magnetic field allows the positioning rod 12 to be more firmly adsorbed on the surface of the weak magnetic magnet 11, which has a reinforcement effect.

[0037] After the lamp panel 4 is fixed, the spring 20 in the lower through groove 9 is compressed into the through groove 9 under the combined effect of its own gravity and the adsorption force of the electromagnet 17. A protective plate 21 is provided on the spring 20 to avoid scratching the lower surface of the lamp panel 4. The compressed spring 20 is prepared for subsequent popping up.

[0038] After the lamp panel 4 is fixed, the patch device 2 and the pressurizer 13 are started, and the patch device 2 pastes the LED lamp chip on the lamp base band 6 to complete the assembly. The pressurizer 13 compresses the air and sprays the compressed air from the air jet pipe 14, which can not only blow away the dust on the LED lamp chip and improve the brightness and durability; and the four air jet pipes 14 are symmetrically distributed around the lamp panel 4, and the sprayed gas forms an airflow thrust, which can prevent the lamp panel 4 from moving during the patch process without contacting the lamp panel 4, thereby realizing the function of auxiliary positioning.

[0039] After the patch is completed, the machine is turned off, and the current of the conductive wire 18 becomes right-in and left-out, changing the direction of the magnetic field of the electromagnet 17, so that the electromagnet 17 repels the lamp panel 4, and the spring 20 also pops out from the through groove 9. Under the action of the repulsive force of the electromagnet 17 and the rebound force of the spring 20, the lamp panel 4 is lifted up by the protective plate 21. The edge height of the lamp panel 4 is higher than the positioning groove 8, which is convenient for the operator or the machine to take the lamp panel 4.

[0040] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
