Description

Technical Field

[0001] This utility model belongs to the field of automotive lighting processing technology, specifically relating to a tooling tray assembly for loading lamp housings. Background Technology

[0002] In existing automated lamp housing production, especially in processes involving precise forward and backward movement and press-fit testing, tooling trays are commonly used for loading and positioning. Traditional tray positioning methods often employ simple slide rails combined with manual pushing and pulling or a single cylinder for limiting, which are prone to displacement due to force, require frequent manual intervention, and are inefficient. In the press-fit testing stage, clamping and fixing the lamp housing usually relies on bolt tightening or structural clips, which is not only cumbersome and time-consuming but also has poor adaptability to different lamp housing specifications. Frequent tooling adjustments are required when changing products, affecting production progress. The movement of the lamp housing on the tray plate mostly relies on manual labor or simple slides, lacking auxiliary movement and precise demolding design, which can easily lead to scratches on the lamp housing surface or difficulty in smooth removal after press-fit testing.

For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0027] Please see Figure 1-6 This utility model provides a technical solution: a tooling tray assembly for loading lamp housings, comprising:

[0028] The loading platform 1 has a tooling tray 2 slidably mounted on its upper surface via a track 9. The guide track 9 guides the movement of the tooling tray 2, ensuring precise trajectory. The tooling tray 2 is used to move the lamp housing workpiece back and forth for press-fit testing and is a key structure connecting various components and enabling lamp housing transfer. The end of the tooling tray 2 has a tray plate 3 for horizontally placing and clamping the lamp housing workpiece for press-fit testing. The surface of the tray plate 3 is precision-machined to ensure stable placement of the lamp housing. Pneumatic clamping mechanisms 7 are located on both sides of the end of the tray plate 3 to pneumatically clamp the placed lamp housing workpiece, enabling quick clamping and fixing of the lamp housing.

[0029] The lower end face of the tooling pallet frame 2 is equipped with electric guide rails 4 on both sides to drive the tooling pallet frame 2 to move. The electric guide rails 4 adopt a high-precision drive method, which can accurately control the moving speed and position of the tooling pallet frame 2. One side of the electric guide rail 4 is equipped with a cable chain 5 to allow the wire harness to follow the tooling pallet frame 2 without interference. The internal space of the cable chain 5 is regular, which can neatly store the wire harness and prevent the wire harness from getting tangled or rubbing against other parts during movement. Two positioning cylinders 6 are provided on both sides of the end of the loading machine table 1 to position the pallet plate 3 for forward and backward movement during loading. The four positioning cylinders 6 are symmetrically distributed and can position the pallet plate 3 from multiple directions, improving positioning stability.

[0030] The electric guide rails 4 are symmetrically installed on the surface of the loading platform 1. This symmetrical layout makes the force on the tooling pallet frame 2 more balanced and the movement more stable. In addition, two electric guide rail seats 8 are slidably installed on each electric guide rail 4. The upper end face of each electric guide rail seat 8 is fixed to both sides of the lower end face of the tooling pallet frame 2. The setting of multiple electric guide rail seats 8 enhances the firmness of the connection between the tooling pallet frame 2 and the electric guide rails 4, ensuring that there is no shaking during the movement.

[0031] A guide rail 9 is provided at the center line of the end of the loading platform 1. The guide rail 9 and the guide rail seat 10 cooperate with each other to further improve the guiding accuracy of the tooling pallet frame 2. The guide rail seat 10 is slidably provided on the guide rail 9. The upper end face of the guide rail seat 10 is fixed at the center position of the lower end face of the tooling pallet frame 2, so that the center position of the tooling pallet frame 2 can also be effectively guided, ensuring the stability of the overall movement.

[0032] The tray plate 3 has through holes 11 evenly spaced on both sides of its surface. The size of the through holes 11 matches the rollers on the movable strip 13, ensuring that the rollers can pass through smoothly. Telescopic cylinders 12 are located on both sides of the through holes 11 at the bottom of the tray plate 3. The telescopic cylinders 12 are characterized by fast response and stable thrust. The piston rod of the telescopic cylinder 12 is fixed to the bottom of the tray plate 3, ensuring a secure installation. A movable strip 13 with multiple rollers is mounted on the piston rod of the telescopic cylinder 12. The rollers are evenly distributed, distributing the weight of the lamp housing evenly and facilitating smoother movement of the lamp housing.

[0033] The rollers on the movable strip 13 are made of wear-resistant material and have a long service life. The rollers can pass through the through hole 11 to the upper end of the tray plate 3 by the extension and retraction of the piston rod of the telescopic cylinder 12, which is used to assist the movement of the car lamp housing on the tray plate 3, reduce the friction between the lamp housing and the tray plate 3, and prevent the surface of the lamp housing from being scratched.

[0034] A top sleeve 14 is provided through one side of the through hole 11 to lift the automotive lamp housing for unloading after press-fitting inspection. The inner wall of the top sleeve 14 is smoothed to reduce friction with the piston rod of the unloading cylinder 15. The unloading cylinder 15 is installed at one end of the top sleeve 14 located at the bottom of the tray plate 3. The piston rod of the unloading cylinder 15 is movably disposed within the top sleeve 14. The top sleeve 14 guides and protects the piston rod, making the extension and retraction of the piston rod smoother. This is used to lift the automotive lamp housing for unloading, and the degree of automation is high.

[0035] Positioning through holes 16 are provided on both sides of the surface of the pallet 3, and the position of the positioning through holes 16 corresponds precisely to the position of the piston rod of the positioning cylinder 6. The piston rod of the positioning cylinder 6 passes through the positioning through holes 16 and is used to position the movement of the pallet 3 before and after loading. The positioning accuracy can reach a high standard, which meets the strict position requirements of press-fitting inspection.

[0036] The pneumatic clamping mechanism 7 includes positioning strips 17 on both sides of the tray plate 3. These positioning strips 17 provide initial positioning of the lamp housing, preventing significant displacement during placement. Fixed blocks 18 are provided at both ends of the positioning strips 17, providing mounting carriers for the clamping cylinder 19 and the clamping top block 20, ensuring a stable structure. The clamping top block 20 extends through one side of the fixed block 18, and its end is equipped with an elastic buffer pad to prevent damage to the lamp housing surface during clamping. The clamping cylinder 19 is located on the other side of the fixed block 18. The air pressure of the clamping cylinder 19 can be adjusted according to the material and hardness of the lamp housing, allowing for controllable clamping force. The piston rod of the clamping cylinder 19 is fixedly connected to one end of the clamping top block 20 using high-strength fasteners to ensure reliable power transmission, enabling the clamping top block 20 to clamp the automotive lamp housing under the push of the clamping cylinder 19.

[0037] Specifically, in use, firstly, the car lamp housing is placed on the tray plate 3, where the positioning strip 17 provides initial positioning. Then, the pneumatic clamping mechanism 7 is activated, and the clamping cylinder 19 pushes the clamping top block 20 to clamp the lamp housing from both sides, ensuring that the lamp housing is stably placed on the tray plate 3.

[0038] Next, the electric guide rail 4 drives the electric guide rail seat 8 to move, which in turn causes the tooling pallet frame 2 to move smoothly on the guide rail 9 using the guide rail seat 10. The cable chain 5 moves with the tooling pallet frame 2 to avoid the wire harness getting tangled or pulled. When the tooling pallet frame 2 moves to the loading or inspection position, the piston rod of the positioning cylinder 6 extends and passes through the positioning through hole 16 on the pallet plate 3 to accurately position the pallet plate 3 for pressing and inspection operations.

[0039] When the lamp housing needs to be adjusted on the tray 3, the telescopic cylinder 12 drives the movable strip 13 to rise, allowing the rollers to pass through the through hole 11 to the upper end of the tray 3, assisting in the easy movement of the lamp housing. After the pressing and testing is completed, the telescopic cylinder 12 drives the rollers to retract, and the piston rod of the unloading cylinder 15 extends along the top sleeve 14, lifting the lamp housing to achieve automatic unloading and facilitate the removal of the lamp housing. After the operation is completed, the piston rod of the positioning cylinder 6 retracts, and the electric guide rail 4 drives the tooling tray frame 2 to reset, waiting for the next loading operation.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
