[0002] A light bulb includes a bulb shell, an inner part, a wick and a lamp holder. In the related art, the installation process of the light bulb generally involves first installing the wick on the inner part, and then inserting the inner part into the bulb shell by a robot. When the inner part is installed on the bulb shell, the inner part only partially protrudes from the bulb shell, and it is difficult for the robot to install the inner part into the bulb shell by clamping the outer wall of the inner part. Therefore, the robot generally clamps the inner part by supporting the inner wall of the inner part. However, the wick has a certain length. Even after the wick is installed on the inner part, the upper end of the wick will still protrude far from the inner part. Therefore, the robot needs to provide an avoidance groove for accommodating the wick corresponding to the wick, resulting in a high production cost of the robot. In addition, if the filament of the wick is deflected to a certain extent, the filament may be touched by the robot when the robot supports the inner part, causing the filament to be further bent, affecting the product yield.

[0046] Reference Figure 1 According to the embodiment of the present application, the light bulb assembly line includes: a conveying device 1000, a bulb shell feeding device 2000, an inner component feeding device 4000 and a wick installation device 3000. Figure 1 The conveying device 1000 is used to convey the bubble shell 8100. Figure 1 The bulb shell loading device 2000 is disposed beside the conveying device 1000, and the bulb shell loading device 2000 is used to load the bulb shell 8100 onto the conveying device 1000. Figure 1 and Fig.15The inner component loading device 4000 is arranged beside the conveying device 1000. The inner component loading device 4000 includes an inner component loading driving member 4120 and an inner component clamping member 4110. The inner component clamping member 4110 is used to clamp the inner component 8200. The inner component loading driving member 4120 drives and connects the inner component clamping member 4110, so that the inner component clamping member 4110 installs the inner component 8200 on the bulb shell 8100 conveyed by the conveying device 1000. Figure 1 and Fig. 9 The wick installation device 3000 is arranged beside the conveying device 1000. The wick installation device 3000 includes a wick loading drive 3120 and a wick loading clamp 3110. The wick loading clamp 3110 is used to clamp the wick 8300. The wick loading drive 3120 drives the wick loading clamp 3110 to enable the wick loading clamp 3110 to insert the wick 8300 into the inner part 8200 assembled on the bulb shell 8100.

[0047] The light bulb assembly line of the present application is used to assemble a light bulb 8000, which includes a bulb shell 8100, an inner part 8200, a wick 8300 and a lamp cap 8400. The bulb shell 8100 includes an integrally formed head 8120 and a base 8110. The outer side of the head 8120 is arc-shaped, and the base 8110 is formed with threads and has an opening 8111 that communicates with the inside of the bulb shell 8100. The inner part 8200 is hollow inside, and the inner part 8200 is at least partially inserted into the inside of the bulb shell 8100 through the opening 8111, and a fixing structure 8210 is provided inside the inner part 8200, and the fixing structure 8210 is formed with a mounting hole 8211. The wick 8300 includes a rubber block 8310 and two filaments 8320. The bottoms of the two filaments 8320 are integrally connected. The rubber block 8310 is connected to the two filaments 8320 to wrap the resistors on the filaments 8320. The filaments 8320 are provided with mounting holes 8211, and the rubber block 8310 is stuck in the mounting holes 8211 to fix the wick 8300 and the inner part 8200 relatively. The lamp cap 8400 is threadedly connected to the base 8110 of the bulb shell 8100, and one of the filaments 8320 is bent between the head 8120 and the lamp cap 8400.

[0048] It can be understood that the bulb shell feeding device 2000 feeds the bulb shell 8100 to the conveying device 1000 in an orderly manner, and the conveying device 1000 is used to convey the bulb shell 8100 so that the bulb shell 8100 passes through the inner component feeding device 4000 and the wick installation device 3000 in sequence. When the bulb shell 8100 is conveyed to the inner component feeding device 4000, the inner component clamping member 4110 clamps the inner component 8200 by means of internal support, and the inner component feeding driving member 4120 drives the inner component clamping member 4110 to approach the bulb shell 8100 on the conveying device 1000, so as to insert the inner component 8200 into the opening 8111 of the head 8120. After the bulb shell 8100 completes the installation of the inner part 8200, the conveying device 1000 conveys the bulb shell 8100 with the inner part 8200 installed to the wick installation device 3000, the wick loading clamp 3110 clamps the wick 8300, and the wick loading drive 3120 drives the wick loading clamp 3110 to approach the bulb shell 8100 of the conveying device 1000 to insert the wick 8300 into the installation hole 8211 of the inner part 8200. Therefore, it should be understood that the light bulb assembly line of the present application first installs the inner part 8200 on the bulb shell 8100, and then inserts the inner part 8200 on the inner part 8200 assembled on the bulb shell 8100, so that the inner part clamping piece 4110 for clamping the inner part 8200 does not need to have a recess for avoiding the wick 8300, which reduces the production cost of the inner part clamping piece 4110, avoids the problem of the inner part clamping piece 4110 damaging the wick 8300, and improves the yield rate of the produced light bulb 8000. The wick feeding clamping piece 3110 can clamp the wick 8300 from the side of the wick 8300, and the wick feeding clamping piece 3110 does not need to have a recess for avoiding the wick 8300, and the wick feeding clamping piece 3110 clamps the outer side of the wick 8300, which is not easy to damage the wick 8300.

[0049] Specifically, the conveying device 1000 includes a conveying medium (not shown in the figure) and a plurality of conveying jigs (not shown in the figure). The conveying medium is, for example, a conveying belt or a conveying chain plate. The conveying jig is arranged on the conveying medium. The conveying jig is used to fix the bulb 8100. The conveying medium rotates to transmit the conveying jig to drive the bulb 8100 to move along the rotation direction of the conveying medium.

[0050] In order to allow the bulb loading device 2000 to output the bulbs 8100 in an orderly manner, refer to Figure 2 , Figure 4 and Figure 5The bulb shell feeding device 2000 includes a material guide component 2100, a material screening component 2200 and a transfer component 2500; the material guide component 2100 is provided with a material guide channel 2120, the material guide component 2100 is used to transport the bulb shell 8100 in the material guide channel 2120, the material guide channel 2120 can be stuck into the base 8110 of the bulb shell 8100 and limit the head 8120 of the bulb shell 8100 from entering; the material screening component 2200 includes a material screening plate 2210, a material screening drive 2220 and a screening box 2230, the screening box 2230 is used to contain A plurality of bulb shells 8100 are housed, a screening box 2230 is arranged above the material guiding component 2100, a discharge port 2231 is opened at the lower end of the screening box 2230, the discharge port 2231 corresponds to the material guiding channel 2120, a screening plate 2210 is arranged in the screening box 2230, a screening drive member 2220 drives and connects the screening plate 2210, and is used for making the screening plate 2210 push the bulb shells 8100 in the screening box 2230; the transfer component 2500 is used for transferring the bulb shells 8100 outputted from the material guiding channel 2120 to the conveying device 1000.

[0051] It can be understood that the screening box 2230 contains a plurality of disorderly stacked bulb shells 8100, and the bulb shells 8100 in the screening box 2230 can fall out through the discharge port 2231 at its lower end, the discharge port 2231 corresponds to the material guide channel 2120, and the bulb shells 8100 output by the discharge port 2231 can fall on the material guide channel 2120. It should be understood that at least part of the width dimension of the material guiding channel 2120 is smaller than the diameter of the head 8120 of the bulb shell 8100 and larger than the diameter of the base 8110 of the bulb shell 8100, so that the material guiding channel 2120 can pass through the base 8110 of the bulb shell 8100 but cannot pass through the head 8120 of the bulb shell 8100, thereby, the material guiding component 2100 supports the head 8120 of the bulb shell 8100, and the base 8110 of the bulb shell 8100 is inserted into the material guiding channel 2120, and the bulb shell 8100 inserted into the material guiding channel 2120 is in a vertical posture with the head 8120 facing upward and the base 8110 facing downward, and the material guiding channel 2120 has a certain length, and the bulb shells 8100 are arranged in order on the material guiding channel 2120 along the length direction of the material guiding channel 2120. The bulb shells 8100 in the material guiding channel 2120 move along the length direction of the material guiding channel 2120 so that the bulb shells 8100 leave the bottom of the screening box 2230 one by one to vacate the position on the material guiding channel 2120 corresponding to the discharge port 2231 of the screening box 2230, so that other bulb shells 8100 in the screening box 2230 can be inserted into the material guiding channel 2120. The bulb shells 8100 that are not inserted into the material guiding channel 2120 will be placed on the material guiding assembly 2100 or stacked on other bulb shells 8100. The bulb shells 8100 will be higher than the material guiding channel 2120. The screening drive 2220 can drive the screening plate 2210 to move or rotate. The screening plate 2210 pushes the bulb shells 8100 that are higher than the material guiding channel 2120 to flip the bulb shells 8100 in the screening box 2230, thereby continuously adjusting the posture and position of the bulb shells 8100 in the screening box 2230, which is conducive to the base 8110 of the bulb shell 8100 being inserted into the material guiding channel 2120. Thus, the screening box 2230 cooperates with the material guide assembly 2100 to screen the bulbs 8100 in a vertical posture, and the screened bulbs 8100 are output in an orderly manner through the material guide assembly 2100, so that the disordered bulbs 8100 in the screening box 2230 are output in an orderly manner through the material guide assembly 2100, and the postures of the bulbs 8100 transmitted by the material guide assembly 2100 are ensured to be consistent. Then, the transfer assembly 2500 can transfer the bulbs 8100 output in an orderly manner by the material guide assembly 2100 to the conveying device 1000.

[0052] Specifically, in order to prevent the bulb 8100 from falling out from between the screening box 2230 and the material guide assembly 2100, the distance between the discharge port 2231 of the screening box 2230 and the material guide assembly 2100 is smaller than the size of the head 8120, and the width of the discharge port 2231 of the screening box 2230 is smaller than the width of the material guide assembly 2100, so that the bulb 8100 can only leave the bottom of the screening box 2230 after being stuck in the material guide channel 2120. Furthermore, in order to improve the discharge efficiency of the screening box 2230, the screening drive 2220 drives the screening plate 2210 to rotate, and the screening plate 2210 can flip the bubble shell 8100 located at the bottom of the screening box 2230 to a higher position and press the bubble shell 8100 located at the top to a lower position. The screening plate 2210 has a better flipping effect on the bubble shell 8100 in the screening box 2230, and the position and posture of the bubble shell 8100 can be adjusted within a larger adjustment range, so that the probability of the bubble shell 8100 being able to be stuck in the material guide channel 2120 is higher, thereby improving the discharge efficiency of the screening box 2230.

[0053] It should be noted that the bulbs 8100 on the material guiding channel 2120 are arranged along the length direction of the material guiding channel 2120, and the heads 8120 of two adjacent bulbs 8100 are in contact with each other. The bulbs 8100 stuck in the material guiding channel 2120 are limited by the head 8120 of the bulbs 8100 supported by the material guiding component 2100. However, the outer side of the head 8120 of the bulb 8100 is arc-shaped and the bulb 8100 is light. The bulb 8100 on the material guiding channel 2120 is easy to swing, and the center of gravity of the bulb 8100 is unstable, which is not conducive to positioning the bulb 8100, and thus not conducive to the transfer component 2500 to grab the bulb 8100. Therefore, referring to Figure 5 and Figure 6 The material guide channel 2120 is formed with a material feeding position 2120a and a material discharging position 2120b along the conveying direction of the material guide component 2100. The material feeding position 2120a can be inserted into the base 8110 of the bulb shell 8100 and restrict the head 8120 of the bulb shell 8100 from entering, and the material discharging position 2120b can pass through the bulb shell 8100; the material discharging port 2231 of the screening box 2230 corresponds to the material feeding position 2120a; the bulb shell feeding device 2000 also includes a material feeding component 2300 and a material loading component 2400. A conveying channel 2311 is formed in the interior of the component 2300 along the vertical direction. The conveying component 2300 is used to convey the bulb shells 8100 along the vertical direction and output them one by one. The feed end 2312 of the conveying channel 2311 is located below the discharge position 2120b; the loading component 2400 is located below the discharge end 2313 of the conveying channel 2311, and is used to carry the bulb shells 8100; the transfer component 2500 is used to transfer the bulb shells 8100 at the loading component 2400 to the conveying device 1000.

[0054] It can be understood that the width of the material feeding position 2120a is smaller than the diameter of the head 8120 of the bulb shell 8100 and larger than the diameter of the base 8110 of the bulb shell 8100, so that the material feeding position 2120a can pass through the base 8110 of the bulb shell 8100 but cannot pass through the head 8120 of the bulb shell 8100, thereby, the material guiding component 2100 supports the head 8120 of the bulb shell 8100, the base 8110 of the bulb shell 8100 is inserted into the material feeding position 2120a, and the material feeding position 2120a has a certain length, so that the bulb shell 8100 inserted into the material feeding position 2120a in the screening box 2230 can leave the bottom of the screening box 2230 to vacate the position corresponding to the material feeding position 2120a and the discharge port 2231 of the screening box 2230. The guide assembly 2100 conveys the bulb 8100 in the guide channel 2120 from the feed position 2120a to the discharge position 2120b. Since the width of the discharge position 2120b is greater than the size of the head 8120 of the bulb 8100, the bulb 8100 can pass through the discharge position 2120b. After the bulb 8100 is conveyed to the discharge position 2120b, the bulb 8100 falls from the discharge position 2120b under the action of gravity and is fed into the feed channel 2311. The end 2312 enters the feed channel 2311, so that the bulb shells 8100 fall into the feed channel 2311 one by one, and the bulb shells 8100 are stacked in the feed channel 2311 along the vertical direction. The feed channel 2311 transports the bulb shells 8100 along the vertical direction, so that the bulb shells 8100 are output one by one from the discharge end 2313 of the feed channel 2311 to the loading component 2400, and then the transfer component 2500 loads the bulb shells 8100 on the loading component 2400 to the conveying device 1000 in an orderly manner. It should be understood that the material guiding component 2100 transfers the bulb shells 8100 from the material feeding position 2120a to the material discharging position 2120b, the material feeding component 2300 receives the bulb shells 8100 dropped from the material feeding position 2120a, and the bulb shells 8100 are converted from being arranged in the length direction of the material guiding channel 2120 to being stacked in the vertical direction. The bulb shells 8100 stacked in the vertical direction are limited on all sides by the inner wall of the material feeding channel 2311, and the upper and lower ends of the bulb shells 8100 are limited by adjacent bulb shells 8100, so that the center of gravity of the bulb shells 8100 is stable, and the bulb shells 8100 can fall one by one and stably on the loading component 2400, so that the transfer component 2500 can load the bulb shells 8100 at the loading component 2400 to the conveying device 1000 in an orderly manner.

[0055] Specifically, the material guide assembly 2100 includes two material guide rods 2110, and a material guide channel 2120 is formed between the two material guide rods 2110. The portion of the material guide rod 2110 corresponding to the material feeding position 2120a is used to support the head 8120 of the bulb shell 8100, and the outer side of the portion of the material guide rod 2110 corresponding to the material discharge position 2120b forms an annular groove so that the width dimension at the material feeding position 2120a becomes larger to allow the head 8120 of the bulb shell 8100 to pass through. The material guide rod 2110 is tilted from high to low along the conveying direction of the material guide assembly 2100, so that the bulb shell 8100 supported by the material guide rod 2110 slides on the material guide rod 2110 in the conveying direction.

[0056] Specifically, in order to make the bulb shell 8100 falling from the discharge position 2120b fall into the feeding channel 2311 more accurately, refer to Figure 6 The bulb shell feeding device 2000 further includes a guide plate 2130 , which is disposed beside the discharge position 2120 b and is used to guide the bulb shell 8100 in the guide channel 2120 to enter the feed channel 2311 .

[0057] It is understandable that after the bulb 8100 is transported to the discharge position 2120b along the material guide channel 2120, the bulb 8100 contacts the guide plate 2130, and the guide plate 2130 guides the bulb 8100 to fall into the material feeding channel 2311. Moreover, it is also understandable that after the material feeding channel 2311 is full, the bulb 8100 at the discharge position 2120b is supported by the bulb 8100 at the top of the material feeding channel 2311, so that the bulb 8100 at the discharge position 2120b cannot fall, and the guide plate 2130 can abut against the outer side of the bulb 8100 at the discharge position 2120b to limit the bulb 8100, and at the same time can reduce the risk of the bulb 8100 at the discharge position 2120b being pushed out by the bulb 8100 at the material feeding position 2120a.

[0058] For the specific structure of the feeding assembly 2300, refer to Figure 7 and Figure 8The feeding assembly 2300 includes a feeding pipe 2310, a connecting frame 2390, a connecting seat 2320, a first material blocking part 2330, a first linkage part 2340, a second linkage part 2350, a second material blocking part 2360, a second elastic part 2372 and a material blocking driving member 2380; a feeding channel 2311 is formed inside the feeding pipe 2310, and a material blocking hole 2314 is opened on the side of the feeding pipe 2310. The first material blocking part 2330 is arranged on the connecting seat 2320 and slidably cooperates with the connecting frame 2390 so that the first material blocking part 2330 can pass through the material blocking hole 2314. The first linkage part 2340 is provided with a plurality of first linkage parts 2340, and the plurality of first linkage parts 2340 are fixedly connected to the connecting seat 2320; the second linkage part 2350 is provided with a plurality of first linkage parts 2340, and corresponds to the first linkage parts 2340 one by one. The second linkage part 2350 is slidably matched with the connecting frame 2390 so that the multiple second linkage parts 2350 can approach or move away from each other; the second linkage part 2350 is slidably matched with the first linkage part 2340 so that the first linkage part 2340 can push the second linkage parts 2350 to move away from each other; there are multiple second material blocking parts 2360, and they correspond one to one with the second linkage parts 2350. The second material blocking parts 2360 are fixedly connected to the second linkage parts 2350, and the second material blocking parts 2360 surround the side of the discharge end 2313 of the feeding channel 2311; the second elastic part 2372 is connected to the second material blocking part 2360, and is used to give the multiple second material blocking parts 2360 an elastic force to approach each other; the material blocking driving member 2380 drives the connection seat 2320 to drive the connecting seat 2320 to move between the first position and the second position. Among them, when the connecting seat 2320 moves from the first position to the second position, the first material blocking part 2330 enters the feeding channel 2311 to abut the bulb shell 8100 in the feeding channel 2311, and the first linkage part 2340 and the second linkage part 2350 slide together, so that the multiple second material blocking parts 2360 move away from each other to allow the bulb shell 8100 to pass through; when the connecting seat 2320 moves from the second position to the first position, the first material blocking part 2330 moves away from the feeding channel 2311 to loosen the bulb shell 8100 in the feeding channel 2311, the first linkage part 2340 moves away from the second linkage part 2350, and the multiple second material blocking parts 2360 move close to each other to limit the passage of the bulb shell 8100.

[0059] It can be understood that a plurality of bulbs 8100 are stacked in the vertical direction in the feed channel 2311 , and the bulbs 8100 can move in the vertical direction. In the initial state, the feeding channel 2311 has output a bulb shell 8100 and has passed through the first blocking part 2330 and the second blocking part 2360 and fallen on the loading assembly 2400, waiting to be taken away by the transfer assembly 2500, and the connecting seat 2320 is in the first position. At this time, the first blocking part 2330 is away from the feeding channel 2311, and the first blocking part 2330 does not abut against the bulb shell 8100 in the feeding channel 2311 to allow the bulb shell 8100 to pass through, while the first linkage part 2340 is away from the second linkage part 2350, and the multiple second blocking parts 2360 approach each other under the action of the second elastic part 2372, and the second blocking part 2360 blocks the discharge end 2313 of the feeding channel 2311 to prevent the first bulb shell 8100 at the bottom of the feeding channel 2311 from passing between the multiple second linkage parts 2350, thereby preventing the feeding channel 2311 from continuing to output the bulb shell 8100. After the transfer assembly 2500 removes the bubble shell 8100 on the loading assembly 2400, the blocking driving member 2380 drives the connecting seat 2320 to move from the first position to the second position. It should be understood that the first blocking portion 2330 is located near the discharge end 2313 of the feeding channel 2311. When the connecting seat 2320 moves from the first position to the second position, the first blocking portion 2330 is close to the feeding channel 2311 and can pass through the blocking hole 2314 to abut against the second bubble shell 8100 at the lower end of the feeding channel 2311 to limit the subsequent The bulb shell 8100 continues to be conveyed, and the first linkage part 2340 will move toward the second linkage part 2350. The first linkage part 2340 and the second linkage part 2350 slide together to push the multiple second linkage parts 2350 away from each other, thereby driving the second blocking parts 2360 on the second linkage parts 2350 to move away from each other, thereby releasing the obstruction of the discharge end 2313 of the conveying channel 2311 to allow the first bulb shell 8100 at the lower end of the conveying channel 2311 to pass between the multiple second linkage parts 2350 and fall onto the loading assembly 2400.After the transfer component 2500 takes away the first bulb shell 8100 that falls on the loading component 2400, the material blocking driving member 2380 drives the connecting seat 2320 to move from the second position to the first position, and the first linkage part 2340 moves away from the second linkage part 2350 to release the thrust on the second linkage part 2350, and the plurality of second material blocking parts 2360 approach each other under the elastic force of the second elastic part 2372, so that the plurality of second material blocking parts 2360 approach each other and re-block the discharge end 2313 of the feeding channel 2311, and the first material blocking part 2330 passes through the material blocking hole 2314 and moves away from the feeding channel 2311 to loosen the second bulb shell 8100 in the feeding channel 2311, so as to allow the second bulb shell 8100 to pass through the first material blocking part 2330 and be blocked by the second material blocking part 2360. It should be understood that at this time, the second bulb shell 8100 will become the first bulb shell 8100 located at the lower end in the feeding channel 2311. This process is repeated so that the bulb shells 8100 pass through the first material blocking portion 2330 and the second material blocking portion 2360 in an orderly manner, and are output from the material delivery channel 2311 in an orderly manner.

[0060] Specifically, refer to Figure 8 The first linkage part 2340 is a rotating wheel, and the second linkage part 2350 is provided with an inclined surface. When the connecting seat 2320 moves from the first position to the second position, the rotating wheel can contact the inclined surface on the second linkage part 2350, and the rotating wheel slides along the inclined surface on the second linkage part 2350, and pushes the second linkage part 2350 to slide relative to the connecting frame 2390, and the rotating wheel can rotate by itself, so that the rotating wheel slides smoothly on the inclined surface of the second linkage part 2350.

[0061] Specifically, the connecting frame 2390 is fixedly connected to the conveying pipe 2310 .

[0062] Specifically, refer to Figure 8 The material feeding assembly 2300 further includes a first elastic portion 2371 , which is connected to the first material blocking portion 2330 and is used to provide an elastic force to the first material blocking portion 2330 to approach the material feeding channel 2311 .

[0063] It can be understood that, in the process of the first material stopping portion 2330 abutting against the bulb shell 8100 near the feeding channel 2311, the first elastic portion 2371 can play a buffering role, so that the first material stopping portion 2330 is not easy to damage the bulb shell 8100. For example, after the first material stopping portion 2330 abuts against the bulb shell 8100 in the feeding channel 2311, the connecting seat 2320 has not reached the second position and needs to continue to move toward the feeding channel 2311. The first material stopping portion 2330 can convert the driving force of the connecting seat 2320 into pressure on the first elastic portion 2371, compressing the first elastic portion 2371, thereby reducing the clamping force of the first material stopping portion 2330 on the bulb shell 8100 and avoiding the first material stopping portion 2330 from crushing the bulb shell 8100. Moreover, in the process that the first linkage part 2340 moves away from the second linkage part 2350, the first elastic part 2371 gradually unfolds and provides an elastic force to the first material stopping part 2330 to keep the first material stopping part 2330 in contact with the bulb shell 8100, so that the second material stopping part 2360 can move together before the first material stopping part 2330 releases the bulb shell 8100, so as to ensure the limiting effect of the second material stopping part 2360 and avoid the first material stopping part 2330 releasing the bulb shell 8100 too quickly, causing the bulb shell 8100 to pass through the second material stopping part 2360 before the second material stopping part 2360 moves together, thereby affecting the orderly transportation of the bulb shell 8100.

[0064] For the specific structure of the material loading assembly 2400, refer to Figure 2 and Figure 3 The loading assembly 2400 includes a loading fixture 2410, a positioning plate 2420, a positioning column 2430, a first loading drive component 2440 and a second loading drive component 2450; a limiting hole 2411 for limiting the bulb shell 8100 is formed on the loading fixture 2410, and the first loading drive component 2440 drives the loading fixture 2410 to drive the loading fixture 2410 to move to the bottom of the feed channel 2311 or to the side of the transfer assembly 2500; the positioning plate 2420 is located below the limiting hole 2411, the positioning column 2430 is fixed to the upper end of the positioning plate 2420, and the second loading drive component 2450 is fixedly arranged on the loading fixture 2410, and drives the connected positioning plate 2420 to make the positioning column 2430 pass through the limiting hole 2411.

[0065] It can be understood that when the loading component 2400 needs to receive the bulb shell 8100 output from the feeding component 2300, the second loading drive component 2450 drives the positioning plate 2420 to rise to drive the positioning column 2430 to rise, and the positioning column 2430 passes through the limiting hole 2411 of the loading fixture 2410, and allows the positioning plate 2420 and the positioning column 2430 to be close to the discharge end 2313 of the feeding channel 2311. The feeding channel 2311 allows the bulb shells 8100 to be output one by one. After the feeding channel 2311 outputs a bulb shell 8100, since the posture of the bulb shell 8100 is that the head 8120 is facing upward and the base 8110 is facing downward, the positioning column 2430 can penetrate into the bulb shell 8100 through the opening 8111, and as the bulb shell 8100 falls, the positioning plate 2420 can support the bulb shell 8100. It should be understood that allowing the positioning column 2430 to receive the bulb shell 8100 close to the discharge end 2313 of the feeding channel 2311 can improve the accuracy of material receiving, and the positioning column 2430 can penetrate into the interior of the bulb shell 8100 to guide the falling process of the bulb shell 8100, and limit the bulb shell 8100 after the bulb shell 8100 leaves the feeding channel 2311. Subsequently, the second loading driving member 2450 drives the positioning plate 2420 to descend, and the positioning column 2430 descends to below the limiting hole 2411, so that the bulb 8100 enters the limiting hole 2411, and the bulb 8100 is limited by the limiting hole 2411. During the descending process of the positioning plate 2420, the outer side of the bulb 8100 can adjust the position of the bulb 8100 through the inner wall of the limiting hole 2411. After the bulb 8100 completely enters the limiting hole 2411, the position of the bulb 8100 is accurate, which is conducive to the subsequent transfer component 2500 to grab the bulb 8100. In addition, the positioning column 2430 inserted into the bulb 8100 can limit the bulb 8100 to prevent the bulb 8100 from being squeezed off by the inner wall of the limiting hole 2411. After the bulb shell 8100 is located in the limiting hole 2411, since the distance between the feeding component 2300 and the loading jig 2410 is relatively close, it is not conducive for the transfer component 2500 to grab the bulb shell 8100. Therefore, the loading jig 2410 is driven to move by the first loading driving component 2440 to make the bulb shell 8100 in the limiting hole 2411 leave the bottom of the feeding channel 2311, so as to facilitate the transfer component 2500 to grab the bulb shell 8100 in the limiting hole 2411 and transfer the bulb shell 8100 to the conveying device 1000.

[0066] For the specific structure of the transfer assembly 2500, refer to Figure 2 and Figure 3The transfer assembly 2500 includes a flipping drive 2510, a bubble shell clamp 2520, a transfer jig 2530, a transfer drive 2540 and a transfer clamp 2550. The bubble shell clamp 2520 and the transfer clamp 2550 are both used to clamp or release the bubble shell 8100. The flipping drive 2510 drives the connected bubble shell clamp 2520 to flip the bubble shell clamp 2520. The transfer drive 2540 drives the connected transfer clamp 2550 to move the transfer clamp 2550 between the transfer jig 2530 and the conveying device 1000.

[0067] It can be understood that the bulb clamping member 2520 clamps the bulb 8100 on the loading jig 2410, and the flip driving member 2510 drives the bulb clamping member 2520 to flip, and the bulb clamping member 2520 flips to the transfer jig 2530, so that the head 8120 of the bulb 8100 is inserted into the transfer jig 2530, thereby adjusting the posture of the bulb 8100 so that the head 8120 of the bulb 8100 at the transfer jig 2530 faces downward and the base 8110 faces upward, so that the opening 8111 of the bulb 8100 faces upward, which is convenient for the subsequent assembly of the inner part 8200, the wick 8300 and the lamp holder 8400 to the bulb 8100. The transfer driving member 2540 drives the transfer clamping member 2550 to clamp the bulb 8100 at the transfer jig 2530, and load the bulb 8100 onto the conveying device 1000.

[0068] In order to improve the installation accuracy of the wick 8300 relative to the inner part 8200, refer to Fig. 9 and Fig.10 The wick installation device 3000 also includes a first guide drive member 3210, a first guide portion 3220 and a second guide portion 3320. The first guide portion 3220 is formed with a first guide channel 3230, and the first guide channel 3230 is used to pass through the wick 8300 clamped by the wick loading clamp 3110; the second guide portion 3320 is formed with a second guide channel 3330, and the second guide channel 3330 is used to pass through the wick 8300 clamped by the wick loading clamp 3110; the guiding range of the second guide channel 3330 is smaller than the guiding range of the first guide channel 3230. Among them, the first guide drive 3210 drives the first guide part 3220 to move the first guide part 3220 between the wick loading clamp 3110 and the second guide part 3320 to connect the first guide channel 3230 with the second guide channel 3330, so that the wick 8300 clamped by the wick loading clamp 3110 can pass through the first guide channel 3230 and the second guide channel 3330 in sequence, or is used to make the first guide part 3220 leave between the wick loading clamp 3110 and the second guide part 3320 to avoid the wick loading clamp 3110.

[0069] It can be understood that the conveying device 1000 conveys the bulb shell 8100 installed with the inner part 8200 to the bottom of the second guide part 3320. When the wick 8300 needs to be inserted into the inner part 8200, the first guide drive member 3210 drives the first guide part 3220 to move to one side of the second guide part 3320 and is located between the wick loading clamp 3110 and the second guide part 3320, and the first guide channel 3230 is connected to the second guide channel 3330. The wick loading clamp 3110 clamps the wick 8300 and is located above the first guide portion 3220. The wick loading drive 3120 drives the wick loading clamp 3110 to move downward so that the lower end of the wick 8300 passes through the first guide channel 3230 and enters the second guide channel 3330. Subsequently, the first guide drive 3210 drives the first guide portion 3220 to leave the bottom of the wick loading clamp 3110 to avoid the descending path of the wick loading clamp 3110, so that the wick loading clamp 3110 can continue to move downward. Fig.17 , so that the wick 8300 passes through the second guide channel 3330 and is inserted into the inner part 8200.

[0070] It should be understood that the first guide channel 3230 penetrates the first guide portion 3220, and the diameter of the first guide channel 3230 decreases from high to low. The second guide channel 3330 penetrates the second guide portion 3320, and the diameter of the second guide channel 3330 decreases from high to low, so that the first guide channel 3230 and the second guide channel 3330 can guide the wick 8300 inserted from high to low. Fig.17 , so that the wick 8300 can be more accurately inserted into the installation hole 8211 of the inner part 8200. And the guiding range of the first guiding channel 3230 is greater than the guiding range of the second guiding channel 3330. The first guiding channel 3230 located at the top can first guide the wick 8300 preliminarily, and the second guiding channel 3330 located at the bottom can further guide the wick 8300. Therefore, the first guiding channel 3230 cooperates with the second guiding channel 3330 to increase the guiding range of the wick 8300, so as to improve the guiding effect of the wick 8300, and ensure the normal installation of the wick 8300 even when the wick 8300 is greatly deflected. Furthermore, after the wick 8300 passes through the first guide channel 3230, the first guide portion 3220 can leave the bottom of the wick loading clamp 3110 to allow the wick loading clamp 3110 to further descend, thereby making the first guide portion 3220 not affect the downward movement of the wick loading clamp 3110, thereby increasing the guiding range without affecting the downward movement path of the wick loading clamp 3110, thereby ensuring that the wick 8300 can be assembled in place.

[0071] Specifically, the guiding range of the first guide channel 3230 is greater than the guiding range of the second guide channel 3330, that is, the maximum diameter of the first guide channel 3230 is greater than the maximum diameter of the second guide channel 3330, and the minimum diameter of the first guide channel 3230 is greater than the minimum diameter of the second guide channel 3330. It should be understood that the diameter of the lower end of the first guide channel 3230 is the minimum diameter of the first guide channel 3230, and the diameter of the upper end of the second guide channel 3330 is the maximum diameter of the second guide channel 3330, so that the diameter of the upper end of the second guide channel 3330 is greater than or equal to the diameter of the lower end of the first guide channel 3230, so as to ensure that the end of the wick 8300 can enter the second guide channel 3330 when passing through the first guide channel 3230, and avoid the second guide channel 3330 being too narrow, so that the wick 8300 passing through the first guide channel 3230 cannot enter the second guide channel 3330. The lower end of the first guide portion 3220 is connected to the upper end of the second guide portion 3320 to avoid a gap between the first guide portion 3220 and the second guide portion 3320 that causes the end of the wick 8300 to be mistakenly inserted, thereby affecting the installation of the wick 8300.

[0072] Regarding the specific form of the first guide portion 3220, refer to Fig.10 The first guide portion 3220 includes at least two first guide blocks 3221. The first guide driving member 3210 drives and connects the first guide blocks 3221 to drive the multiple first guide blocks 3221 to approach or move away from each other. When the multiple first guide blocks 3221 approach each other, the multiple first guide blocks 3221 are enclosed to form a first guide channel 3230. When the first guide blocks 3221 move away from each other, the first guide blocks 3221 leave the bottom of the wick loading clamp 3110.

[0073] It is understandable that when the wick 8300 needs to be guided, the first guide driving member 3210 drives one or more first guide blocks 3221 to approach each other so that the first guide blocks 3221 are connected and enclosed to form the first guide channel 3230. When the wick feeding clamp 3110 needs to be avoided, the first guide driving member 3210 drives the guide blocks to move away from each other so that a space allowing the wick feeding clamp 3110 to pass through is formed between the first guide blocks 3221, and the wick feeding clamp 3110 passes between the multiple first guide blocks 3221 to move further downward.

[0074] Furthermore, after the wick 8300 is installed, the conveying device 1000 conveys the bulb shell 8100 with the wick 8300 installed thereon away, and when the first guide blocks 3221 move away from each other, the wick 8300 installed on the inner component 8200 can be avoided.

[0075] In order to further improve the installation stability of the wick 8300 relative to the inner part 8200, refer to Fig.10 The wick installation device 3000 includes a second guide driving member 3310, which drives and connects the second guide portion 3320 to make the second guide portion 3320 leave between the wick loading clamp 3110 and the conveying device 1000 to avoid the wick loading clamp 3110.

[0076] It can be understood that after the end of the wick 8300 passes through the second guide channel 3330 and is inserted into the mounting hole 8211 of the inner part 8200, the second guide drive 3310 drives the second guide part 3320 to leave the bottom of the wick loading clamp 3110 to avoid the wick loading clamp 3110, so that the wick loading clamp 3110 can move further downward, and the wick 8300 is further inserted into the inner part 8200, thereby improving the connection stability and tightness between the wick 8300 and the inner part 8200.

[0077] For the specific structure of the second guide portion 3320, refer to Fig.10 The second guide portion 3320 includes at least two second guide blocks 3321, and the second guide driving member 3310 drives and connects the second guide blocks 3321 to drive the multiple second guide blocks 3321 to approach or move away from each other; when the multiple second guide blocks 3321 approach each other, the multiple second guide blocks 3321 are enclosed to form a second guide channel 3330; when the second guide blocks 3321 move away from each other, the second guide blocks 3321 leave the bottom of the wick loading clamp 3110 to avoid the wick loading clamp 3110.

[0078] It is understandable that when the wick 8300 needs to be guided, the second guide driving member 3310 drives one or more second guide blocks 3321 to approach each other so that the second guide blocks 3321 are connected and enclosed to form a second guide channel 3330. When the wick feeding clamp 3110 needs to be avoided, the second guide driving member 3310 drives the second guide blocks 3321 to move away from each other so that a space allowing the wick feeding clamp 3110 to pass through is formed between the second guide blocks 3321, and the wick feeding clamp 3110 passes through the plurality of second guide blocks 3321 to move further downward.

[0079] To improve the accuracy of Wick 8300 installation, refer to Fig.10The wick installation device 3000 further includes a bulb limiting block 3341 corresponding to the second guide block 3321. The bulb limiting block 3341 is fixed below the second guide portion 3320. When a plurality of bulb limiting blocks 3341 are close to each other, the plurality of bulb limiting blocks 3341 enclose a limiting space 3350. The limiting space 3350 is used to accommodate the bulb 8100 to limit the bulb 8100. Since the bulb limiting blocks 3341 correspond to the second guide block 3321 one by one and are fixedly connected, the second guide driving member 3310 can drive the bulb limiting blocks 3341 and the second guide block 3321 to synchronously approach or move away from each other. In the initial state, the plurality of bulb stop blocks 3341 are relatively far away from each other to avoid the bulb 8100 transported by the conveying device 1000. After the conveying device 1000 transports the bulb 8100 to between the bulb stop blocks 3341, the second guide drive 3310 drives the bulb stop blocks 3341 to approach each other, so that the bulb stop blocks 3341 surround the bulb 8100 and form a limit space 3350, so that the bulb 8100 is located in the limit space 3350, which limits the bulb 8100. If the bulb 8100 is skewed, the bulb stop blocks 3341 can guide the bulb 8100 in the process of approaching each other. After the installation of the wick 8300 is completed, the second guide drive 3310 drives the bulb stop blocks 3341 to move away from each other, so that the conveying device 1000 can transport the bulb 8100 with the wick 8300 installed away.

[0080] Specifically, the second guide driving member 3310 is connected to the bulb limit block 3341, and drives the second guide block 3321 to move by driving the bulb limit block 3341. In some other embodiments, the second guide driving member 3310 can also directly drive the second guide block 3321 to move, and drive the second guide block 3321 to drive the bulb limit block 3341 to move.

[0081] To bend the wick 8300, refer to Fig.11 , Fig.13 and Fig.14 The light bulb assembly line of the present application further comprises a guiding assembly 3400, a wire drawing assembly 3500 and a bending assembly 3600, wherein the guiding assembly 3400, the wire drawing assembly 3500 and the bending assembly 3600 are sequentially arranged on the side of the conveying device 1000 along the conveying direction of the conveying device 1000; the guiding assembly 3400 is used to guide the wick 8300 on the inner part 8200, referring to Fig.11 The guiding assembly 3400 includes a guiding drive 3410 and at least two guiding blocks 3420. The guiding drive 3410 drives and connects a plurality of guiding blocks 3420 to form a guiding channel 3430 so that the plurality of guiding blocks 3420 are enclosed to form a guiding channel 3430. The guiding channel 3430 is used to accommodate a plurality of filaments 8320 on the wick 8300. Fig.13The wire drawing assembly 3500 includes a translation drive member 3510, a wire drawing drive member 3520 and at least two wire drawing blocks 3530. The wire drawing drive member 3520 drives and connects a plurality of wire drawing blocks 3530 to form a wire drawing channel for accommodating one of the filaments 8320 on the wick 8300. The translation drive member 3510 drives and connects the wire drawing drive member 3520 to make the wire drawing drive member 3520 translate to bend the filament 8320 in the wire drawing channel. Fig.14 The bending assembly 3600 includes a second lifting drive member 3610 and a bending head 3620. The second lifting drive member 3610 drives the bending head 3620 to make the bending head 3620 press down the bent filament 8320 to bend the filament 8320.

[0082] It can be understood that the conveying device 1000 conveys the bulb 8100 with the wick 8300 installed thereon through the guiding assembly 3400, the wire drawing assembly 3500 and the bending assembly 3600 in sequence, and the state of the wick 8300 is referred to as Fig.17 The conveying device 1000 conveys the bulb 8100 with the wick 8300 to the bottom of the guiding assembly 3400, and the two filaments 8320 on the wick 8300 are located between the guiding blocks 3420. The guiding drive member 3410 drives the plurality of guiding blocks 3420 to approach each other. In the case that the filament 8320 is deflected, the filament 8320 will be pushed by the guiding blocks 3420 to correct the filament 8320 into the guiding channel 3430, so as to guide the filament 8320. It should be noted that, since the filament 8320 is relatively soft and the cross-sectional size of the guiding channel 3430 is larger than the cross-sectional size of the filament 8320, the guiding block 3420 only pushes the filament 8320 and does not clamp the filament 8320, thereby avoiding clamping the deflected filament 8320. In addition, the guiding channel 3430 extends along the distribution direction of the two filaments 8320. When the wick 8300 is installed deflected, resulting in the two filaments 8320 being distributed deflected, the guiding block 3420 can push the filament 8320 as they approach each other, thereby driving the rubber block 8310 of the wick 8300 to rotate a certain angle in the mounting hole 8211 on the inner part 8200, so that the distribution direction of the two filaments 8320 is correct, thereby facilitating the subsequent wire drawing assembly 3500 to accurately clamp the filament 8320, thereby avoiding the wire drawing assembly 3500 failing to clamp the filament 8320 or the wire drawing direction being incorrect.

[0083] After the guiding assembly 3400 completes the guiding of the filament 8320, the conveying device 1000 conveys the bulb 8100 to the wire drawing assembly 3500, where one filament 8320 will be located between the wire drawing blocks 3530, and the wire drawing drive 3520 drives the wire drawing blocks 3530 to approach each other so that the wire drawing blocks 3530 clamp or surround the filament 8320 to limit the filament 8320, and then, the translation drive 3510 drives the wire drawing drive 3520 to translate, so as to drive the wire drawing block 3530 to translate, so that the wire drawing block 3530 bends the limited filament 8320 in the horizontal direction to achieve the initial bending of the filament 8320.

[0084] After the wire drawing assembly 3500 completes the preliminary bending of the filament 8320, the conveying device 1000 conveys the bulb 8100 to the bending assembly 3600, and the bulb 8100 is located below the bending head 3620. The second lifting drive member 3610 drives the bending head 3620 to descend, so that the bending head 3620 is pressed down to further bend the preliminary bent filament 8320. Fig.16 , so that one of the filaments 8320 is bent until it is close to or close to the head 8120 of the bulb shell 8100, so as to complete the bending of one filament 8320.

[0085] In summary, before the filament 8320 is bent, the filament 8320 is guided by the guiding block 3420 in cooperation with the guiding driver 3410, so as to improve the accuracy of subsequent bending, thereby improving the product yield. After the filament 8320 is guided, the wire drawing block 3530, the wire drawing driver 3520 and the translation driver 3510 are used to achieve the preliminary bending of one of the filaments 8320, and then the preliminary bent filament 8320 is further bent by the bending head 3620 in cooperation with the second lifting driver 3610, so that one of the filaments 8320 is bent to be close to or close to the head 8120 of the bulb shell 8100. The filament 8320 is gradually bent through two steps, so as to improve the accuracy of the bending of the filament 8320, and reduce the risk of the filament 8320 breaking due to a single bending, thereby further improving the product yield.

[0086] It should be noted that, since the filament 8320 is relatively soft, in the process of the wick feeding clamp 3110 clamping the filament 8320 to insert the wick 8300 into the mounting hole 8211 of the inner part 8200, in order to reduce the risk of the filament 8320 bending during the installation process and to facilitate the guide block 3420 to drive the rubber block 8310 to rotate in the mounting hole 8211, the wick feeding clamp 3110 is in the process of inserting the wick 8300 into the inner part 8200. Do not fully install the wick 8300. First partially insert the rubber block 8310 into the mounting hole 8211 to reduce the downward pressure of the wick loading clamp 3110 on the filament 8320 during the installation process and reduce the risk of bending of the filament 8320. In addition, since the rubber block 8310 is only partially inserted into the mounting hole 8211, the friction between the rubber block 8310 and the inner wall of the mounting hole 8211 is small, which can facilitate the rotation of the rubber block 8310 relative to the mounting hole 8211.

[0087] Then, in order to install the wick 8300 relative to the inner part 8200, refer to Fig.12 , the lower end of the guide block 3420 is provided with a protrusion 3421, referring to Fig.11 The guiding assembly 3400 also includes a first lifting drive member 3440 , which drives the connected guiding block 3420 to make the protrusion 3421 abut against the rubber block 8310 on the wick 8300 .

[0088] After the guiding block 3420 completes the guiding of the filament 8320, the first lifting drive member 3440 drives the guiding drive member 3410 to descend, so as to drive the guiding block 3420 to descend, so that the protrusion 3421 at the lower end of the guiding block 3420 is inserted into the interior of the inner part 8200, and the protrusion 3421 is abutted against the rubber block 8310 on the wick 8300, so as to push the wick 8300 to be further inserted into the mounting hole 8211, so that the wick 8300 is installed in place, so that the wick 8300 and the inner part 8200 are tightly connected.

[0089] It should be understood that after the rubber block 8310 is completely inserted into the mounting hole 8211 , the protrusion 3421 can continue to move downward to abut against the inner component 8200 , so that the inner component 8200 and the bulb 8100 are more tightly connected.

[0090] Specifically, two guide blocks 3420 are provided. After the two guide blocks 3420 abut against each other to form the guide channel 3430, the protrusions 3421 on the two guide blocks 3420 are arranged at intervals to allow the filament 8320 to pass through between the two guide blocks 3420, thereby avoiding interference between the guide blocks 3420 and the filament 8320. The cross-sectional size of the rubber block 8310 is relatively large, and the protrusions 3421 on the two guide blocks 3420 can respectively abut against the two sides of the upper end of the rubber block 8310 to push the rubber block 8310.

[0091] Specifically, the lamp panel assembly line of the present application further includes a lamp holder installation device 5000, a filament cutting device 6000 and a rivet installation device 7000. The filament cutting device 6000, the lamp holder installation device 5000 and the rivet installation device 7000 are sequentially arranged on the side of the conveying device 1000 along the conveying direction of the conveying device 1000. The lamp holder installation device 5000 is used to install the lamp holder 8400 to the head 8120 of the bulb shell 8100. The lamp holder 8400 and the head 8120 of the bulb shell 8100 clamp the bent filament 8320, and another filament 8320 will pass through the lamp holder 8400. The filament cutting device 6000 is used to cut the filament 8320 passing through the lamp holder 8400. The rivet installation device 7000 is used to install the rivet 8410 on the lamp holder 8400 so that the lamp holder 8400 can seal the bulb shell 8100.

[0092] The embodiments of the present application are described in detail above in conjunction with the accompanying drawings, but the present application is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the purpose of the present application. In addition, the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.
