Description

Technical Field

[0001] The utility model relates to the technical field of production and manufacturing, and specifically relates to the technical field of a lamp assembly production line. Background Art

[0002] Lamp manufacturing is a multi-step process, involving multiple links such as feeding of components, assembly, welding, and inspection. And lamp manufacturing has its own unique manufacturing problems, such as the vulnerability of the LED light source of the lamp and the problem of uneven lighting caused by the angular deviation after assembly.

[0003] Especially when using through-hole LED lamp beads as the light source, it is more fragile. During improper assembly operations or transportation, its lifespan is shortened or even directly damaged, increasing the production cost. And if the problems cannot be detected in time and directly flow to the next link, the increased cost will be even more.

[0004] Regarding this problem, for example, Chinese Patent CN201711023242.2, a protection mechanism for a production line of LED lamps, discloses a solution to prevent the LED lamps on the conveying device from falling to the bottom surface through a conveying device and a protection device.

[0005] That is to say, in the current lamp production, there is indeed an increase in the production line cost caused by lamp damage, and thus there is a need for a convenient and safe layout of the lamp assembly production line. Content of the Utility Model

[0006] In order to solve the above problems, the utility model provides a lamp assembly production line, aiming to improve the overall production efficiency and reliability of lamps through an integrated lamp assembly production line.

[0007] To achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A lamp assembly production line includes a tabletop, sprockets arranged at both ends of the tabletop, a transmission chain connecting the sprockets to form a looped transmission line, and an assembly cart installed on the transmission chain and synchronously driven with it and capable of loading products.

[0009] The transmission chain includes chain links arranged vertically and horizontally offset, connecting pins connecting the chain links. The chain links are provided with positioning holes in the middle, and the assembly cart is installed on the transmission chain through the positioning holes.

[0010] It also includes a feeding area, an assembly area, a fastening area, an inspection area, and a discharging area, which are sequentially arranged along the moving direction of the assembly cart on the outer periphery of the transmission chain.

[0011] Compared with the prior art, the loop-shaped transmission line formed by the transmission chain in this case drives the assembly vehicle when the transmission chain rotates, which can reduce the conveying cost and improve the safety while loading products on the assembly vehicle. By using its loop-shaped feature, a full-process operation area from feeding to discharging is set along the moving direction of the assembly vehicle, and the assembly to inspection is carried out coherently, which greatly avoids the damageable links of the LED lamp beads.

[0012] In some embodiments, the assembly vehicle is provided with moving wheels on the opposite side of the transmission chain. The use of the moving wheels can reduce the stress on the transmission chain, enabling the assembly vehicle on the assembly line to smoothly load products and operate.

[0013] In the preferred embodiment, the moving wheels are two universal wheels.

[0014] In some embodiments, the assembly vehicle is provided with a product placement surface. The product placement surface is inclined downward from the inner side towards the outer side in the direction of the transmission chain, and a baffle is provided at the outer edge of the product placement surface. In this way, it is convenient to pick up and place products during operation, and the design of the baffle can prevent the products from falling.

[0015] In some embodiments, the product placement surface is provided with an anti-slip and anti-static plate.

[0016] In some embodiments, the assembly vehicle is provided with positioning pieces, and the positioning pieces are provided with mounting holes corresponding to the positioning holes.

[0017] In the preferred embodiment, there are two mounting holes, and the mounting hole at the rear end is a straight slot hole that enables the positioning piece to be movably connected.

[0018] In some embodiments, protective frames with a side-view concave shape for encapsulating the transmission chain are respectively provided on both sides of the transmission chain.

[0019] In the preferred embodiment, at least a part of the assembly vehicle is located above the protective frame, so that even if the assembly vehicle is deformed under load, it will not damage the transmission chain but be supported by the protective frame.

[0020] In some embodiments, it further includes a storage platform arranged in the loop of the transmission chain, and a lighting area is provided on the upper part of the storage platform. Description of the Drawings

[0027] The features of the present utility model and other related features are further described in detail through the following embodiments for the understanding of those skilled in the same industry:

[0028] It should be noted that the words "upper" and "lower", "left" and "right" used in the following description refer to the positional relationship in the spatial range. The words "inner" and "outer" are also used to refer to the directions towards or away from the geometric center of a specific component respectively. Figure 1 The arrow direction in

[0029] Please refer to Figure 1 and Figure 2 , the overall top view and side view schematic diagrams of a kind of lamp assembly production line in this case. The production line includes a tabletop 1 as the working surface. Sprockets 2 are arranged at both ends of the tabletop 1, and a transmission chain 3 is used to connect the two sprockets 2 to form a loop transmission line. At this time, an assembly vehicle 4 capable of loading products is installed on the transmission chain 3 to make it synchronously drive with the transmission chain 3.

[0030] On the outer periphery of the transmission chain 3, a loading area, an assembly area, a fastening area, an inspection area, and an unloading area are sequentially arranged along the moving direction of the assembly vehicle 4. As shown in the figure, in order to describe the surrounding operation, that is, the assembly vehicle rotates in a cycle, the assembly to inspection can be carried out coherently, which greatly avoids the damage links of the LED lamp beads. In actual application, the position intervals of its outer periphery can be adjusted according to different products, and the regional scope of this case is not limited.

[0031] Please refer to Figure 1 and Figure 2 , there is a large part of space in the middle ring of the transmission chain 3. By using this space, a storage table 11 is set up, on which hand pieces such as operation tools can be placed. At the same time, an illumination area 12 is arranged above the storage table 11. The illumination area 12 can be arranged on both sides, and an operation instruction manual 13 can be arranged in the middle. In this way, even if a rotatable assembly vehicle 4 is arranged on the tabletop 1, it will not affect the functions of placing objects and illumination in the conventional production line.

[0032] The difficulty of this case lies in how to set up an effective space to make the transmission chain 3 drive the assembly vehicle 4 to move without affecting the functions of the traditional production line. For this, please refer to Figure 5and Figure 6 The transmission chain 3 includes chain links 31 arranged in an offset manner vertically and horizontally, and connecting pins 32 connecting the said links. At this time, a positioning hole 33 is provided in the middle of the chain link 31 of this case, and the assembly vehicle 4 is installed on this transmission chain 3 through this positioning hole 33. In this way, when the transmission chain 3 rotates, it drives the assembly vehicle 4, which can reduce the transportation cost and improve safety at the same time.

[0033] Please continue to refer to Figure 5 and Figure 6 The assembly vehicle 4 is provided with a positioning piece 41, which is a thinner sheet extending from the outer edge of the assembly vehicle 4 and thinner than the main frame of the assembly vehicle 4. There are mounting holes corresponding to the positioning holes 33 on the positioning piece 41. Here, mounting pins 42 are provided at the mounting holes. As shown in the figure, the position where the mounting pin 42 is located is the position of the mounting hole, which is not shown in the figure.

[0034] In actual application, some of the assembly vehicles 4 in this case will move along a loop. Therefore, considering the displacement at the corner, the mounting holes at the rear end are designed as straight slot holes 43 that can movably connect the positioning piece 41. In this way, when rotating, the mounting pin 42 can move in the straight slot hole 43 to adjust the angle.

[0035] For the specific design of the assembly vehicle 4, please refer to Figure 3 and Figure 4 First, on the premise that one end of the assembly vehicle 4 is fixed to the transmission chain 3, a moving wheel 44 is provided on the opposite side of the assembly vehicle 4 to the transmission chain 3. The moving wheel 44 can be used to reduce the force on the transmission chain 3, so that the assembly vehicle 4 on the assembly line can smoothly load products and run. Considering that it needs to turn, it is preferred that the moving wheel 44 is two universal wheels arranged in the front-rear direction.

[0036] The assembly vehicle 4 is provided with a product placement surface 45, and the product placement surface 45 is inclined downward from the inner side in the direction of the transmission chain 3 towards the outer side. At this time, a baffle 46 is provided at the outer edge of the product placement surface 45. When operating the product in this way, because it is obliquely arranged from the outside, that is, the operator's angle is closer to the straight-ahead visual angle, it is convenient for observation and picking and placing. At the same time, the design of the baffle 46 can prevent the product from falling. And, an anti-slip and anti-static plate can also be provided on the product placement surface 45, which is very suitable for the product assembly related to circuit boards.

[0037] Please continue to refer to Figure 3 and Figure 4, After all, the transmission chain 3 is a moving mechanism. For safety reasons, protective frames 34 are respectively arranged on both sides thereof. Specifically, they are two concave structures when viewed from the side, that is, the two concave inner concave surfaces sandwich the transmission chain 3 and are arranged facing each other. At this time, at least a part of the assembly vehicle 4 is located above the protective frame 34. Even if the assembly vehicle 4 is deformed due to load, it will not damage the transmission chain 3, but will be supported by the protective frame 34. Moreover, as mentioned above, the positioning piece 41 can be a relatively thin sheet. Therefore, its bending degree can be adjusted to adapt to the product line, and this is also a feature that can be achieved on the premise of being protected by the protective frame 34.

[0038] As described above, the present case protects a lamp assembly production line. All technical solutions identical or similar to the present case should be regarded as falling within the protection scope of the present case.
