Description

Technical Field

[0001] This utility model belongs to the field of LED filament manufacturing equipment, and specifically relates to an LED material box loading and unloading device. Background Technology

[0002] An LED filament is an optical device composed of LED chips arranged in a filament shape. Its most significant characteristic is its ability to emit light from any angle (360 degrees), achieving high brightness, high luminous efficacy, and a high color rendering index (CRI) without the need for auxiliary optical components. During the manufacturing process, to save labor and increase product protection, LED filaments are often transported between processes in rows or sheets into a material box. An loading / unloading device automatically loads and unloads the filaments from the material box at the processing equipment. However, in existing technologies, the mounting brackets of the loading / unloading devices are often fixed in shape and fit snugly against the material box. However, due to manufacturing errors in the material boxes and errors caused by the limiting frame or clamping parts during assembly, the fit between the support and the material box is prone to be poor. This can result in the material box being loosely assembled or in a skewed state when the support is supporting it, affecting the subsequent loading and unloading of LED filaments. In addition, it is not applicable when assembling different types of material boxes. Furthermore, when the support and the material box are in an uneven mating state, it is not easy to straighten them due to friction and jamming at the contact point between the support and the material box. Forcibly straightening them can easily damage the material box and the support, requiring the material box to be picked up and placed again, which is time-consuming, laborious, and inconvenient. Utility Model Content

[0003] (a) Technical problems to be solved To overcome the shortcomings of existing technologies, an LED box loading and unloading device is proposed. This addresses the problem that existing devices often use a fixed support that fits snugly against the box. However, due to manufacturing errors and misalignments caused by the limit frame or clamping components during assembly, the fit between the support and the box is often poor. This results in the box becoming loosely assembled or tilted when the support is holding it, affecting subsequent LED filament loading and unloading. Furthermore, this device is incompatible with different box models. When the support and box are unevenly aligned, friction and locking at the contact point make it difficult to straighten. Forcibly straightening them can damage both the box and the support, requiring the box to be removed and repositioned, which is time-consuming, laborious, and inconvenient.

Detailed Implementation

[0019] The present invention will be further described in detail below with reference to the embodiments, but the implementation of the present invention is not limited thereto.

[0020] Example 1: This utility model provides an LED material box loading and unloading device: its structure includes a first telescopic component 1, an assembly table 2, a limiting frame 3, a support 7 and a slot 10. The limiting frame 3 is fixed on the assembly table 2, and the slot 10 is provided through the assembly table 2. The support 7 passes through the slot 10 and is located within the range of the limiting frame 3. The first telescopic component 1 is used to drive the support 7 to rise and fall. The support 7 includes a fixed base 701, an assembly base 702, a first sliding member 703, a side plate 704, a second sliding member 705, a third sliding member 706, a first clamping plate 707, a balance bar 711, an assembly groove 712, and a second telescopic member 713. The bottom of the assembly base 702 is fixed to the fixed base 701, and an assembly groove 712 is formed between the assembly base 702 and the fixed base 701. A side plate 704 is fixed to one end of the assembly base 702. The second sliding member 705 is located above the side plate 704 adjacent to the first clamping plate 707, and the first sliding member 703 is located at the top of the assembly base 702 adjacent to the side plate 704. The mounting base 702 is provided with a balance bar 711 on the side away from the side plate 704. The lower side of the first clamping plate 707 is slidably sleeved on the balance bar 711. The top of the first clamping plate 707 is higher than the mounting base 702. The second telescopic member 713 is fixed in the mounting groove 712. The second telescopic member 713 is used to drive the first clamping plate 707 to slide on the balance bar 711. A third sliding member 706 is provided above the side of the first clamping plate 707 adjacent to the side plate 704. The first sliding member 703, the second sliding member 705 and the third sliding member 706 are all used for the sliding adjustment of the material box when the first clamping plate 707 clamps the material box.

[0021] The first telescopic member 1 and the second telescopic member 713 are hydraulic rods, pneumatic rods and electric push rods, respectively.

[0022] The LED box loading and unloading device also includes an ejection mechanism 4, which is used to eject the LED light board from the box.

[0023] The LED box loading and unloading device also includes a fourth telescopic member 5 and a second clamping plate 6. One end of the fourth telescopic member 5 is fixed to the limiting frame 3, and the other end of the fourth telescopic member 5 is connected to the second clamping plate 6. The second clamping plate 6 is used to clamp the loading box on the limiting frame 3. The fourth telescopic member 5 is used to drive the second clamping plate 6 to perform clamping extension and retraction. The fourth telescopic member 5 is the same as the first telescopic member 1 or the second telescopic member 713.

[0024] The LED box loading and unloading device also includes a limiting rod 8 and a conveyor belt 9. The conveyor belt 9 is mounted on the top of the assembly table 2 and is used to transport the boxes that are lowered onto the assembly table 2. The limiting rod 8 is fixed to the assembly table 2 and is used to limit the side movement of the boxes when the conveyor belt 9 is transporting them.

[0025] In use, the material box is assembled at the limiting frame 3, and the material box is supported by the support 7 and slides at the limiting frame 3. The limiting frame 3 is used to limit the position of the material box. When assembling multiple material boxes, a stacking assembly method is adopted. The support 7 supports the bottom material box and drives all material boxes to slide. When it is necessary to discharge the material, the second clamping plate 6 can be driven by the fourth telescopic member 5 to clamp the second material box from the bottom. Then the support 7 lowers the bottom material box to the conveyor belt 9, and the support 7 is continuously lowered by the first telescopic member 1, so that the material box changes from being supported by the support 7 to being supported by the conveyor belt. Then the material box can be sent out by the conveyor belt 9. When adding material boxes, they are directly stacked on the top of the limiting frame 3. When discharging the material box, the ejection mechanism 4 is used to eject the LED filament array or plate in the material box. Before the support 7 supports the utensil, the second telescopic member 713 first drives the first clamping plate 707 to slide away from the side plate 704, so that the support 7 is in the unfolded state. When support is needed, the second telescopic member 713 drives the first clamping plate 707 to slide towards the side plate 704, so that the first clamping plate 707 contacts and clamps the utensil between the assembly base 702, the side plate 704 and the first clamping plate 707. When the first clamping plate 707 slides and clamps, the balance bar 711 can make the sliding smoother and share the force of the first clamping plate 707 and the second telescopic member 713, which can better clamp the utensil and ensure the stability of the utensil assembly. At the same time, when the utensil is tilted relative to the support 7, if it tilts towards the first clamping plate 707, the utensil will contact the third sliding member 706 of the first clamping plate 707. As the first clamping plate 707 closes, it can... The box can be directly returned to its upright position for clamping. If it is tilted towards the side plate 704, the side of the box will contact the second sliding member 705 of the side plate 704, and the bottom of the box will contact the first sliding member 703 of the side plate 704. As the first clamping plate 707 closes, the box will smoothly return to its normal fitting position under the sliding of the first sliding member 703 and the third sliding member 706. If it is tilted in other directions, since there is no limiting such as the side plate 704, it can be directly pressed back to its upright position by the mounting base 702, preventing friction and jamming that could prevent proper fitting. This ensures smooth sliding of the box during clamping, thereby achieving automatic adjustment and ensuring the fitting degree of the box and the support 7. It can also prevent damage to the box or support due to friction between the box and the support 7, and can better adapt to different box sizes for assembly, preventing situations such as box production errors or incompatibility between different models of boxes.

The roller assembly 70501 is composed of multiple rollers arranged together. The sliding belt 70502 is sleeved on the roller assembly 70501. The sliding belt 70502 is flush with the side plate 704 on the side adjacent to the first clamping plate 707. The assembly groove 70503 is located above the side plate 704 on the side adjacent to the first clamping plate 707. The roller assembly 70501 is assembled in the assembly groove 70503. The side plate 704 on the side end face of the assembly groove 70503, adjacent to the first clamping plate 707, is also provided with a clearance groove 70504 that is lower than the sliding belt 70502.

[0027] The sliding belt 70502 is made of rubber.

[0028] Among them, the first sliding member 703 and the third sliding member 706 are the same components with the same structure but different orientations compared with the second sliding member 705. The mounting groove 70503 of the first sliding member 703 is located at the top of the side plate 704 of the mounting base 702. The clearance groove 70504 of the first sliding member 703 is lower than the top of the sliding band 70502 of the first sliding member 703. The top of the sliding band 70502 of the first sliding member 703 is flush with the top of the mounting base 702. The mounting groove 70503 of the third sliding member 706 is located above the side plate 704 of the first clamping plate 707. The clearance groove 70504 of the third sliding member 706 is lower than the side plate 704 of the sliding band 70502 of the third sliding member 706. The side plate 70502 of the third sliding member 706 is flush with the side plate 704 of the first clamping plate 707.

[0029] This embodiment specifically discloses the structure of the sliding component, which enables the material box to slide smoothly when it is stuck or in other situations, while the rest of the structure and effect remain unchanged.

The first sliding member 703 and the second sliding member 705 have the same structure. The mounting groove 70503 of the first sliding member 703 is located on the top of the side of the mounting base 702 adjacent to the side plate 704. The first detection plate 708 is fixed to the top of the side of the mounting base 702 away from the side plate 704 by the first elastic pad 715. The first pressure sensor 714 is used to detect the pressure borne by the first detection plate 708. The top of the sliding band 70502 of the first sliding member 703 is flush with the top of the first detection plate 708. The top of the side end face of the mounting groove 70503 of the first sliding member 703 is also provided with a relief groove 70504 that is lower than the top of the sliding band 70502 of the first sliding member 703.

[0031] The first elastic pad 715 is made of rubber.

[0032] When the device is in use, the support 7 can detect whether it is in contact with the material box according to the first pressure sensor 714. When the first pressure sensor 714 senses contact with the material box, it can automatically control the second telescopic member 713 to drive the first clamping plate 707 to clamp the material box, which is convenient for automated control. The rest of the structure and effect remain unchanged.

[0033] Example 4: Compared to the previous embodiments, the support 7 in this embodiment further includes a second pressure sensor 709, a second detection plate 710, and a second elastic pad 716. The third sliding member 706 has the same structure as the second sliding member 705. The assembly groove 70503 of the third sliding member 706 is located above the side of the first clamping plate 707 adjacent to the side plate 704. The second detection plate 710 is fixed below the side of the first clamping plate 707 adjacent to the side plate 704 by the second elastic pad 716. The second pressure sensor 709 is used to detect the pressure borne by the second detection plate 710. The sliding band 70502 of the third sliding member 706 adjacent to the side plate 704 is flush with the side of the second detection plate 710 adjacent to the side plate 704. The end face of the assembly groove 70503 of the third sliding member 706 adjacent to the side plate 704 is also provided with a relief groove 70504 lower than the sliding band 70502 of the third sliding member 706.

[0034] The second elastic pad 716 is made of rubber.

[0035] When the device is in use, the clamping pressure of the first clamping plate 707 can be detected to prevent the first clamping plate 707 from clamping the material box too hard and causing damage to the device or the material box. This ensures clamping stability and increases safety in use, while the rest of the structure and effect remain unchanged.

[0036] Example 5: Compared to the previous embodiments, the ejection mechanism 4 in this embodiment includes a third telescopic member 401, a body 402, a push rod 403, a connecting joint 404, and an elastic pad 405. The body 402 is fixed to the limiting frame 3. The third telescopic member 401 is assembled inside the body 402. The push rod 403 is fixed to the side of the third telescopic member 401 adjacent to the limiting frame 3.

The side of the connecting joint 404 adjacent to the push rod 403 is smaller than the side away from the push rod 403. The elastic pad 405 is sleeved and assembled on the connecting joint 404. The push rod 403 and the elastic pad 405 pass through the body 402 on the side away from the third telescopic member 401. The third telescopic member 401 is used to drive the push rod 403 and the elastic pad 405 to telescopically move towards the limiting frame 3. The third telescopic member 401 is the same as the first telescopic member 1 or the second telescopic member 713.

[0037] The elastic pad 405 is made of rubber.

[0038] When the device is in use, the ejection mechanism 4 can extend the ejector rod 403 through the third telescopic member 401 to eject the material stored in the material box. During ejection, the elastic pad 405 is used for flexible contact to reduce damage to the stored material. At the same time, the elastic pad 405 is assembled in the form of wrapping around the connector 404. The connector 404 has a structure where the side adjacent to the ejector rod 403 is smaller than the side away from the ejector rod 403, which facilitates the quick replacement of the elastic pad 405 by the elasticity of its own material. The rest of the structure and effect remain unchanged.
