Description

Technical Field

[0001] This utility model belongs to the technical field of light source production equipment, specifically relating to a lampshade gripping machine adapted to linear light sources and ring light sources. Background Technology

[0002] In the automated assembly of lighting products, the gripping and placement of lampshades are crucial steps affecting overall production efficiency and assembly accuracy. Traditional lampshade clamping devices are typically designed for specific shapes or sizes, such as specialized clamps for linear or ring-shaped lampshades. These clamps achieve positioning through mechanical or pneumatic means and release the lampshade to a designated station after transfer. While such equipment is suitable for high-speed production lines with fixed structures, it exhibits limitations in flexible manufacturing environments with diverse product types and small batches.

[0003] Existing lampshade gripping mechanisms are often single-function and cannot simultaneously adapt to the assembly requirements of various light source structures such as linear and circular ones. Especially when the size and specifications of the lampshade change, it is often necessary to replace or significantly adjust the clamping module, or even replace the entire gripping equipment, which leads to extended changeover time on the production line, low equipment reuse rate, and seriously affects production flexibility and assembly efficiency. Utility Model Content

[0004] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a lampshade gripping machine that is compatible with linear light sources and ring light sources, so as to solve the technical problems of poor adaptability of lampshade gripping and high replacement frequency in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] This utility model includes a feeding cross and four clamping blocks. The four clamping blocks are respectively fixedly and slidably disposed on the four extension beams of the feeding cross. At least two of the clamping blocks are laterally slidably provided with elastic stop pins for blocking the lower side of the lampshade.

[0007] Optionally, it also includes a retrieval component disposed inside the clamping stop block, wherein the retrieval component causes the elastic stop pin to retract into the clamping stop block as the gripping telescopic cylinder moves downward.

[0008] Optionally, the clamping stop includes an upper block and a stop post, and the recycling assembly includes a vertical post and a recycling spring. The upper block is slidably disposed on the extension beam of the feeding cross, the vertical post is fixedly disposed on the lower side of the upper block, the lower end of the vertical post is slidably disposed inside the stop post, the recycling spring abuts against the middle section of the vertical post and the inside of the stop post, the lower end of the vertical post is provided as an inclined surface, the elastic stop pin is laterally moved disposed inside the stop post and extends from the side of the stop post, the inner end of the elastic stop pin has an insertion hole, the vertical post moves down and abuts into the insertion hole, so that the elastic stop pin retracts into the inside of the stop post.

[0009] Optionally, the clamping block further includes a lower block and a stop post. The lower block is fixed to the upper end of the stop post. The vertical post passes through both the lower block and the stop post. The upper end of the stop post is vertically slidably disposed within the lower block. The upper end of the stop post is fixedly connected to the stop post through a crossbeam. The stop post moves up and down with the vertical post and abuts against the upper side of the clamped lampshade.

[0010] Optionally, the abutment is an elastic telescopic column.

[0011] Optionally, a locking screw is also included, which passes through the upper block and abuts against the extension beam of the unloading cross.

[0012] Optionally, it also includes a gripping moving vehicle, a lampshade transfer rail, and a gripping telescopic cylinder. The gripping moving vehicle moves on the lampshade transfer rail, and the gripping telescopic cylinder is fixedly mounted on the gripping moving vehicle. The gripping telescopic cylinder drives the unloading cross to move up and down.

[0013] Optionally, the lower end of the gripping telescopic cylinder is fixedly connected to the four ends of the feeding cross via support rods.

[0014] The beneficial effects of this utility model are as follows: This device is equipped with a lampshade gripper that can clamp elongated or circular lampshades; the gripping moving carriage and the gripping telescopic cylinder move laterally and vertically in coordination, and the feeding cross carries four clamping stops to clamp and release the lampshade. The four clamping stops are adjusted in position along the four extension beams of the feeding cross, so that when clamping elongated lampshades, the four clamping stops clamp and position the four sides of the elongated lampshade, and when clamping circular lampshades, they clamp and position the outer side of the circular lampshade at four points. This is achieved by symmetrically setting two stops. The elastic stop pin on the underside of the lampshade supports the lampshade. When the material tray moves to this station, the gripping trolley moves to directly above the light source on the material tray. As the gripping telescopic cylinder moves downward, the recycling component inside the clamping stop block retracts the elastic stop pin, and the lampshade falls from top to bottom into the light source base, thus placing the lampshade. This utility model can be adapted to linear light sources of different lengths and widths, as well as circular light sources with different outer diameters. This device can be quickly adjusted according to the production needs of the product, reducing the time for device adjustment and line changeover, and greatly improving assembly efficiency and production flexibility.

[0023] The following embodiments are for illustrative purposes only. These embodiments can be combined and are not limited to the content shown in any single embodiment below.

[0024] This utility model provides a lampshade gripper that is compatible with both linear and ring light sources, such as... Figures 1-3 As shown, the device includes a gripping telescopic cylinder 412, a feeding cross 413, and four clamping stops 414. The four clamping stops 414 are slidably and fixably mounted on the four extension beams of the feeding cross 413. At least two of the clamping stops 414 have elastic stop pins 4141 slidably mounted laterally on their sides to block the lower side of the lampshade. The device also includes a recovery assembly 415 disposed inside the clamping stops 414. The recovery assembly 415 moves with the gripping telescopic cylinder 412. The elastic stop pin 4141 is moved and retracted into the clamping block 414; it also includes a gripping moving carriage 411 and a lampshade transfer guide rail 43. The gripping moving carriage 411 moves on the lampshade transfer guide rail 43. The gripping telescopic cylinder 412 is fixedly mounted on the gripping moving carriage 411. The gripping telescopic cylinder 412 drives the unloading cross 413 to move up and down. The lower end of the gripping telescopic cylinder 412 is fixedly connected to the four ends of the unloading cross 413 through support rods.

[0025] This utility model includes a lampshade gripper capable of holding elongated or circular lampshades. A gripping moving vehicle 411 and a gripping telescopic cylinder 412 move laterally and vertically in coordination. A feeding cross 413 carries four clamping stops 414 to grip and release the lampshade. The four clamping stops 414 are adjusted in position along the four extension beams of the feeding cross 413, so that when gripping an elongated lampshade, the four stops clamp and position it on all four sides; when gripping a circular lampshade, the four stops clamp and position it at four points on the outer side. The lampshade is symmetrically positioned with two stops below the lampshade. The elastic stop pin 4141 on the side can support the lamp cover. When the material tray moves to this station, the gripping moving cart 411 moves to directly above the light source of the material tray. As the gripping telescopic cylinder 412 moves down, the recycling component 415 in the clamping stop block 414 retracts the elastic stop pin 4141, and the lamp cover falls from top to bottom into the light source base, realizing the placement of the lamp cover. This utility model can be adapted to linear light sources of different lengths and widths, as well as circular light sources with different outer diameters. This device can be quickly adjusted according to the production needs of the product, reducing the device adjustment and line change time, and greatly improving assembly efficiency and production flexibility.

[0026] like Figures 1-3 As shown, the clamping stop 414 includes an upper block 4142 and a stop post 4143, and the recycling assembly 415 includes a vertical post 4151 and a recycling spring 4152. The upper block 4142 is slidably disposed on the extension beam of the unloading cross 413 and also includes a locking screw 44, which passes through the upper block 4142 and abuts against the extension beam of the unloading cross 413. The vertical post 4151 is fixedly disposed on the lower side of the upper block 4142. The lower end of the vertical column 4151 is slidably disposed within the stop post 4143. The retraction spring 4152 abuts against the middle section of the vertical column 4151 and the interior of the stop post 4143. The lower end of the vertical column 4151 is provided with an inclined surface. The elastic stop pin 4141 is laterally movable within the stop post 4143 and extends from the side of the stop post 4143. The inner end of the elastic stop pin 4141 has an insertion hole. When the vertical column 4151 moves downward and abuts into the insertion hole, the elastic stop pin 4141 retracts into the interior of the stop post 4143.

[0027] In this structure, the stop posts 4143 are used to block the four sides of the lampshade, clamping and limiting the lampshade. The blocking can be set as follows: Figure 2The stepped structure shown in the diagram allows the step structure to be positioned at the outer edge of the lampshade base as the feeding cross 413 moves downward above the light source base, supporting and lowering the stop post 4143. As the feeding cross 413 continues to move downward, the upper block 4142 and the vertical post 4151 overcome the retraction spring 4152 and move downward. The lower inclined surface of the vertical post 4151 inserts into the sliding hole 41411 of the elastic stop pin 4141, causing the elastic stop pin 4141 to retract into its interior. With the elastic stop pin 4141 retracted, the lampshade can fall directly into the light source base. The feeding cross 413 moves upward, and the vertical post 4151 moves elastically upward along the stop post 4143. The elastic stop pin 4141 pops out from the stop post 4143, allowing for the next clamping and installation of the lampshade. This scheme achieves automatic linkage between clamping and releasing of the lampshade through the inclined drive of the vertical post 4151 and the cooperation of the elastic stop pin 4141. The automatic retraction of the 4141 elastic stop pin ensures the lampshade falls accurately and without collision into the base, significantly improving placement accuracy and product yield. The overall structure is stable and reliable, with a high degree of automation, further enhancing the assembly efficiency of the equipment's light source.

[0028] In further proposals, such as Figures 1-3 As shown, the clamping block 414 further includes a lower block 4144 and a stop post 4145. The lower block 4144 is fixed to the upper end of the stop post 4143. The vertical post 4151 passes through both the lower block 4144 and the stop post 4143. The upper end of the stop post 4145 is vertically slidably disposed within the lower block 4144. The upper end of the stop post 4145 is fixedly connected to the stop post 4143 via a crossbeam. The stop post 4145 is an elastic telescopic column. The stop post 4145 moves up and down with the vertical post 4151 and abuts against the upper side of the clamped lampshade.

[0029] In this design, by setting up a lower block 4144 and a stop post 4145, the stop post 4145 can abut against the upper side of the lampshade when clamping it. As the feeding cross 413 moves downwards, the stop post 4145 presses downwards against the lampshade. Combined with the retraction of the elastic stop pin 4141, this quickly pushes the lampshade into the light source base, preventing the lampshade from getting stuck on the clamping stop block 414 and effectively solving the risk of the lampshade getting stuck or not being placed correctly. This design significantly improves the success rate and consistency of lampshade installation, further enhances the stability and automation level of the equipment, and further improves the overall assembly capability.

[0030] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
