Description

Technical Field

[0001] The present invention relates to the technical field of corn lamp installation and production, and in particular to a jig for assembling corn lamps. The jig is suitable for a corn lamp production line. Background Art

[0002] LED corn light is a kind of LED lamp, belonging to the light source category, 360 degrees around the light, its shape and lamp beads are like corn cobs, so it is called LED corn light. However, the fan heat problem of corn light has always been criticized in the industry, such as Figure 1 The above is a schematic diagram of the structure of a side LED reflector assembly 1, comprising a side light shield 2, a side LED lamp board 3, and a heat dissipation strip 4. The heat dissipation strip is closely attached to the back of the side LED lamp board to dissipate heat. Therefore, the heat dissipation strip is particularly sophisticated. The side surface of the heat dissipation strip, facing away from the side light shield, is equipped with a plurality of inner heat dissipation fins 5 extending along the length and width of the heat dissipation strip. Outer heat dissipation fins 6 are also provided on both sides of the heat dissipation strip. The side of the corn lamp is assembled by assembling 6 to 8 side LED reflector assemblies. However, due to the large size of the corn lamp, the 6 or 8 side LED reflector assemblies are first assembled into a regular polygon, and then the lamp head and base are attached. However, one hand can only position 3 to 4 of the side LED reflectors, while the other hand completes the installation of the remaining side LED reflectors one by one. During the installation process, the side LED reflectors are supported by hand. This can cause the assembly of several side LED reflectors to collapse before they are fully installed, which is time-consuming, labor-intensive, and inefficient. Furthermore, after installation, the overall appearance of the corn light will be affected and the workmanship will not be exquisite. Specifically, the 6 or 8 side LED reflector assemblies cannot be accurately combined into a regular hexagon or octagon through manual positioning, which affects the appearance of the product.

[0003] The applicant designed a fixture that facilitates the accurate positioning and installation of several side LED reflector assemblies based on the complex heat dissipation structure on the back of the heat dissipation strips. Summary of the Invention

[0004] The purpose of the present invention is to solve the above technical problems, and the technical solution adopted is:

[0005] A fixture for assembling corn lamps, wherein the corn lamp is circumferentially composed of several side LED reflector assemblies, the side LED reflector assemblies including side light-transmitting covers, side LED lamp bead boards, and heat dissipation strips arranged sequentially from the outside to the inside, the heat dissipation strips being in close contact with the back of the side LED lamp bead boards, and several inner heat dissipation fins being arranged on the back of the heat dissipation strips, characterized in that the inner heat dissipation fins are provided with connecting strips, the fixture includes a base and a positioning plate mounted on the base, the positioning plate includes a regular polygonal body, each corner of the body extending outwardly to provide a connecting portion, the connecting portion is fan-shaped, the radius of the fan is perpendicular to the side of the regular polygonal body, a rectangular installation space is formed between two adjacent connecting portions, the installation space accommodates the heat dissipation strips, vertical grooves are provided on both sides of the connecting portion, and the vertical grooves accommodate the connecting strips.

[0006] Corn lamps are large in size and cannot be produced on ordinary assembly lines, so jigs must be used. The jigs allow several side LED reflector assemblies to be accurately positioned one by one to form a circle, eliminating the need for manual support and freeing up labor. The circle of side LED reflector assemblies will not collapse and can accurately form multiple shapes, resulting in a neat and exquisite appearance.

[0007] Furthermore, the base includes a cylindrical seat and a circular ring platform mounted on the cylindrical seat.

[0008] Furthermore, the diameter of the circular platform is larger than the diameter of the circle on which the positioning plate is located. When the eight side LED reflector assemblies are installed on the fixture, the bottom of each side LED reflector assembly rests on the upper surface of the circular platform, maintaining the flatness of the upper and lower end surfaces of the eight side LED reflector assemblies, which is more convenient for subsequent assembly of the lamp head and base.

[0009] Furthermore, the side LED reflector assembly is inserted between two adjacent connecting parts from the bottom, wherein the heat dissipation strip is located in the installation space, and the connecting strips on both sides of the heat dissipation strip are located in corresponding vertical grooves.

[0010] As an option, the corn lamp is composed of six side LED reflector assemblies in the circumference, and the positioning plate includes a regular hexagonal body.

[0011] As another option, the corn lamp is composed of eight side LED reflector assemblies in the circumference, and the positioning plate includes a regular octagonal body.

[0012] The applicant also proposed a production line for assembling corn lamps, which includes the above-mentioned jig, and utilizes a circular production line with a special jig installed on the line body.

[0013] Preferably, the production line further comprises a square tray mounted on the guide rail, and the jig is mounted on the tray, so as to be used for assembly line production and automation.

[0014] Preferably, the production line further includes an isosceles trapezoidal tray mounted on the guide rails and a delivery device. The tray is provided with a jig mounting slot. The delivery device comprises a turntable, a delivery channel disposed on the turntable, and a torsion spring mounted on the turntable via a short shaft. The turntable is also provided with a limit pin for the torsion spring. The outlet of the delivery channel is opposite the mounting slot, and the torsion spring is located inside the delivery channel. The torsion spring comprises a first curved segment, a force storage segment, a connecting segment, a deforming segment, and a second curved segment. The force storage segment is located inside the delivery channel, and its shape aligns with the circular arc surface inside the delivery channel. The force storage segment contacts the base of the jig, and the deforming segment contacts the limit pin. In conventional production lines according to the present invention, workers are required to manually transfer the jig-mounted tray to the guide rails of the production line, which is inconvenient. A further improvement is to add a delivery device. The assembly of the side LED reflector assembly onto the jig is completed outside the production line, and the jig is delivered to the tray via the delivery device, thereby improving production efficiency.

[0015] Preferably, elastic sheets are provided on both sides of the installation slot to firmly limit the fixture in the installation slot.

[0016] Compared with the prior art, the present invention has the following beneficial effects: it realizes the precise installation of several side LED reflector assemblies, makes the overall appearance of the lamp beautiful, and saves time and labor. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] The following further illustrates the embodiments of the present invention in conjunction with the accompanying drawings and implementation methods. The positional relationship described herein is consistent with the positional relationship direction of the accompanying drawings and is only for the convenience of description and does not limit the structure of the present invention.

[0028] Example 1

[0029] As mentioned in the background technology, the heat dissipation strips 4, such as Figure 4 As shown, the applicant adds a connecting strip 7 outwards of the two outermost inner heat dissipation fins on the back of the heat dissipation strip. The connecting strip is used to facilitate the installation of each side LED reflector assembly on the fixture below.

[0030] The fixture includes a positioning plate 8 and a base 9, such as Figure 2 and 3 , the positioning plate has a certain thickness and is similar to the shape of a regular octagon. Specifically, an inverted triangle extends outward from each right angle of the regular octagon. In a stricter sense, it is described as a fan-shaped shape. The center angle of the fan-shaped shape is 10 degrees. The fan-shaped shape is defined as a connecting portion 10, and the connecting portion has two straight-sided sides and a circular arc surface. A vertical groove 11 is respectively provided on each of the straight-sided sides of the connecting portion, and the position of the vertical groove 11 is closer to the circular arc surface of the connecting portion. The circular arc surface is adapted to the shape of the above-mentioned outer heat dissipation fin 6. The base includes a cylindrical seat 12 and a circular ring stage 13 mounted on the cylindrical seat. The positioning plate can be mounted on the cylindrical seat, and can also be slotted and installed at the upper end of the cylindrical seat. The circular ring stage divides the cylindrical seat into an upper cylindrical seat and a lower cylindrical seat, and the lower cylindrical seat is mounted on the tray, such as Figure 6 , allowing the entire fixture to be installed on the tray. The diameter of the circular ring platform is larger than the diameter of the circle on which the positioning plate is located. That is, when the eight side LED reflector assemblies are installed on the fixture, the bottom of each side LED reflector assembly rests on the upper surface of the circular ring platform, maintaining the flatness of the upper and lower end surfaces of the eight side LED reflector assemblies, which is more convenient for the subsequent assembly of the lamp head and base.

[0031] The side LED reflector assembly is mounted on the fixture, which requires the cooperation of the connecting strip 7 and the vertical slot. There is a rectangular space between each two connecting parts to accommodate a number of inner heat dissipation fins, and the vertical slot accommodates the connecting strip. Figure 5 As shown, the two outermost inner fins and their respective connecting strips form a first right-angled side 14 and a second right-angled side 15, respectively; the straight sides of the connecting portion and their respective vertical grooves form a third right-angled side 16 and a fourth right-angled side 17, respectively. The distance L1 between the leftmost and rightmost inner fins shown in the figure is equal to the distance L2 between two adjacent connecting portions.

[0032] In this embodiment, the two outermost inner heat dissipation fins are further provided with positioning strips extending outwards. The positioning strips are located above the connecting strips, and the distance between the positioning strips and the connecting strips is equal to the distance from the vertical groove to the outermost side of the connecting portion, making the side LED reflector assembly more securely installed.

[0033] Installation steps: Each side LED reflector assembly is inserted into the rectangular space from its lower end. Specifically, the connecting strips are inserted into their respective vertical slots, with the first right-angled side abutting the third right-angled side, and the second right-angled side abutting the fourth right-angled side. The lower end face of the side LED reflector assembly is then pressed against the circular ring table to complete the positioning and installation of the side LED reflector assembly. All eight reflectors are installed in sequence, forming a regular octagon. The lamp head is then installed, and the entire product is removed from the fixture, flipped 180 degrees, and finally installed on the base. Screwing and soldering operations can be automated using a robotic arm.

[0034] The jig is used on an assembly line 20 , the tray 18 is mounted on a guide rail 19 , and the jig is mounted on the tray.

[0035] Example 2

[0036] The difference from Example 1 is the shape and structure of the tray in the corn light installation line. Figure 8 and 9As shown, the assembly line is annular, and the tray 18 is shaped like an isosceles trapezoid, with the long straight side of the tray 18 in close contact with the outside of the assembly line. A mounting slot 21 for the jig is located in the middle of the long straight side of the tray. Elastic plates 22 are located on either side of the mounting slot to hold the jig in place, preventing it from detaching during movement. Adjacent trays are in contact with each other in the straight section of the assembly line. A delivery device 23 is mounted on the outside of the straight section. The delivery device includes a turntable 24 that can rotate about its center. The two ends of the turntable are symmetrically arranged, with a delivery channel 25 at one end. A torsion spring 26 is mounted on the turntable via a pin, allowing it to rotate on the pin. The turntable also has a stop pin 32 for the torsion spring. The stop pin elastically deforms against one end of the torsion spring, while the other end holds mechanically stored energy. This other end also contacts the jig, imparting a certain amount of mechanical energy to the jig. Specifically, the torsion spring 26 includes a first curved segment 27, a force storage segment 28, a connecting segment 29, a deformation segment 30, and a second curved segment 31. The force storage segment is located inside the delivery channel and contacts the base of the fixture. The deformation segment 30 contacts the limit pin. When the deformation segment 30 moves to Figure 9 In the dashed area, the deformable segment 30 does not deform, and the entire torsion spring has no accumulated mechanical energy. The worker presses the second curved segment 31 to disengage the deformable segment 30 from the stop pin 32. The worker presses the protrusion between the deformable segment 30 and the second curved segment 31, and the torsion spring 26 returns to its initial state and regains its deformation. The first curved segment 27 prevents the torsion spring from pressing against the long straight edge of the pallet when the jig is activated.

[0037] Working process:

[0038] The end of the turntable closest to the assembly line is the delivery end, while the other end is the installation end. The torsion spring at the installation end is not in a deformed state. The worker assembles the eight side LED reflector assemblies on the jig located on the delivery channel. The turntable rotates 180 degrees, and the installation end becomes the delivery end. The worker adjusts the torsion spring so that the force storage section contacts the base 9 of the jig. When the mounting slot of the tray moves to a position opposite the delivery channel, the jig is ejected into the mounting slot. As the tray moves along the assembly line, the robotic arm completes tasks such as screw locking and soldering.

[0039] The present invention is not limited to the above-mentioned embodiments, and various changes can be made within the scope of knowledge possessed by ordinary technicians in this field without departing from the scope of the present invention.
