Description

Technical Field

[0001] This utility model relates to the field of automotive headlight lens crimping devices, and in particular to an automotive headlight lens crimping device. Background Technology

[0002] The lens of a car headlight needs to be snapped into a lens holder, and the structure of the lens and lens holder is designed with error prevention features. One commonly used pressing tool is an upper mold that holds the lens in place and presses it into the lens holder;

[0003] For example, the utility model disclosed in CN220973390U discloses an automotive headlight lens pressing device, in which the height of the top block is greater than the height of the lens bracket protruding from the cavity. The top block contacts the support plate before the lens bracket, preventing damage to the lens bracket due to direct contact with the support plate during pressing. However, existing automotive headlight lens pressing devices mostly use suction cups to pick up the lens. But suction cups may fall off during subsequent lens transportation, causing damage to the lens, resulting in poor overall practicality. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, this utility model provides an automotive headlight lens pressing device. This device addresses the problem that existing automotive headlight lens pressing devices have a top block height greater than the lens bracket protruding from the cavity, and the top block contacts the support plate before the lens bracket, preventing damage to the lens bracket due to direct contact with the support plate during pressing. However, existing automotive headlight lens pressing devices often use suction cups to pick up the lens, which can lead to the lens falling off during subsequent transportation, causing damage and resulting in poor overall practicality.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a pressing device for automotive headlight lenses, including a base, a top frame welded to the top of the base, a cylinder fixedly installed at the middle of the top of the top frame, a lifting seat fixedly connected to the bottom of the cylinder, a guide rod fixedly installed on one side of the top of the lifting seat, an adsorption seat fixedly installed at the middle of the bottom of the lifting seat, a suction hole opened at the bottom of the adsorption seat, an air outlet groove opened on the side wall of the adsorption seat, a guide frame installed in the inner cavity of the adsorption seat, an air extractor installed on the inner side of the guide frame, a filter cotton adsorption net distributed on one side of the air extractor, and a clamping structure distributed on one side of the adsorption seat.

[0006] As a preferred technical solution of this utility model, the clamping structure includes a side plate, a clamping plate, a movable rod and a first spring. The side plate is fixedly installed on the bottom side of the lifting seat, and the clamping plate is distributed on the bottom side of the side plate. The movable rod is fixedly installed on the side wall of the clamping plate, and the first spring is sleeved on the outer side of one end of the movable rod.

[0007] As a preferred embodiment of the present invention, a pressing seat is fixedly installed at the top center of the base, and a damper is provided in the inner cavity of the pressing seat. A pressing platform is fixedly connected to the top of the damper, and a protrusion is provided on the side wall of the pressing platform.

[0008] As a preferred embodiment of this utility model, a buffer rod is fixedly installed on one side of the bottom of the pressing table, and a second spring is sleeved on the outer side of the bottom of the buffer rod, and a groove is provided on the inner side wall of the pressing seat.

[0009] As a preferred embodiment of this utility model, the bottom of the adsorption seat is provided with an arc-shaped surface, and the suction holes are equidistantly distributed on the lower surface of the adsorption seat.

[0010] As a preferred embodiment of this utility model, the pressing platform is slidably connected to the pressing seat through the buffer rod, and the buffer rod is symmetrically distributed on both sides of the bottom of the pressing platform.

[0011] Compared with the prior art, the beneficial effects that this utility model can achieve are:

[0012] 1. By combining the designed adsorption base, air pump, and suction holes, the lens can be easily and effectively adsorbed and clamped. Compared with the existing adsorption method using suction cups, it has higher safety and can effectively prevent the lens from falling off during subsequent handling. It is more practical. When the air pump is working, it will draw out air. When the lens is locked in the arc-shaped groove at the bottom of the adsorption base, the negative pressure will make the lens adhere to the bottom of the adsorption base, thus facilitating the subsequent handling of the lens. It is convenient, fast, and has higher stability.

[0013] 2. By combining the damper, buffer rod, and second spring, the structure can effectively buffer and protect the lens during the subsequent pressing process with the housing. This prevents damage to the housing caused by excessive pressing force. When the pressing table moves longitudinally, it will drive the buffer rod to move longitudinally as well. Then, the buffer rod will drive the second spring to deform. At the same time, the damper will also deform under the pressing action of the pressing table. The combined reaction force generated by the deformation of the two will achieve the purpose of buffering and protection. Attached Figure Description

[0019] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation are all within the protection scope of this utility model without creative effort.

[0020] Example

[0021] Please refer to Figure 1 , Figure 2 and Figure 4 As shown, this utility model provides a crimping device for automotive headlight lenses, including a base 1, a top frame 2 welded to the top of the base 1, a cylinder 3 fixedly installed at the middle of the top of the top of the top frame 2, a lifting seat 4 fixedly connected to the bottom of the cylinder 3, a guide rod 5 fixedly installed on one side of the top of the lifting seat 4, an adsorption seat 6 fixedly installed at the middle of the bottom of the lifting seat 4, a suction hole 7 opened at the bottom of the adsorption seat 6, an air outlet groove 8 opened on the side wall of the adsorption seat 6, a guide frame 9 installed in the inner cavity of the adsorption seat 6, an air extractor 10 installed on the inner side of the guide frame 9, a filter cotton adsorption net 11 distributed on one side of the air extractor 10, and a clamping structure distributed on one side of the adsorption seat 6.

[0022] In use, the housing to be crimped is placed inside the crimping table 18, and then the lens is adsorbed by the adsorption seat 6. Then, the lens is crimped by the movement of the lifting seat 4.

[0023] As a further implementation of this embodiment, such as Figure 1 , Figure 2 and Figure 3 As shown, a top frame 2 is welded to the top of the base 1, and a cylinder 3 is fixedly installed at the middle of the top of the top of the top frame 2. A lifting seat 4 is fixedly connected to the bottom of the cylinder 3, and a guide rod 5 is fixedly installed on one side of the top of the lifting seat 4. An adsorption seat 6 is fixedly installed at the middle of the bottom of the lifting seat 4, and a suction hole 7 is opened at the bottom of the adsorption seat 6. An arc-shaped surface is opened at the bottom of the adsorption seat 6, and the suction holes 7 are evenly distributed on the lower surface of the adsorption seat 6. An air outlet groove 8 is opened on the side wall of the adsorption seat 6. A guide frame 9 is installed in the inner cavity of the adsorption seat 6, and a vacuum pump 10 is installed inside the guide frame 9. A filter cotton adsorption mesh 11 is distributed on one side of the air compressor 10. The side plate 12 is fixedly installed on the bottom side of the lifting seat 4. A clamping plate 13 is distributed on the bottom side of the side plate 12. A movable rod 14 is fixedly installed on the side wall of the clamping plate 13. A first spring 15 is sleeved on the outer side of one end of the movable rod 14. One end of the first spring 15 is fixedly connected to the side wall of the side plate 12, and the other end is fixedly connected to the surface of one end of the movable rod 14. The side plate 12, the clamping plate 13, the movable rod 14 and the first spring 15 form a clamping structure, and the clamping structure is set on the bottom side of the lifting seat 4.

[0024] In use, first place the lens at the bottom of the adsorption base 6, then release the lateral force applied to the two movable rods 14. The reverse force generated by the deformation of the first spring 15 will cause the movable rods 14 to return to their lateral position, thus pushing the clamping plate 13 laterally. Combined with the opposing movement of the clamping plates 13 on both sides, this achieves initial clamping and limiting of the lens. At this time, the air pump 10 operates by drawing air through the suction hole 7 at the bottom of the adsorption base 6. The air then passes through the filter cotton adsorption screen 11 inside the guide frame 9, thus achieving simple air purification. The air is filtered and purified, and then the extracted air is discharged through the air outlet 8. At the same time, under the action of negative pressure, the lens will be tightly attached to the bottom of the adsorption seat 6, which can ensure the stability of the lens during subsequent handling and prevent the lens from falling off. During the pressing, the cylinder 3 works to push the lifting seat 4 longitudinally, which in turn pushes the adsorption seat 6 longitudinally to realize the longitudinal movement of the lens, which facilitates the subsequent pressing process. When the lifting seat 4 moves longitudinally, the guide rod 5 will move longitudinally along the top frame 2, which can improve the stability of the lifting seat 4 during the longitudinal movement.

[0025] As a further implementation of this embodiment, such as Figure 1 and Figure 4As shown, a pressing seat 16 is fixedly installed at the top center of the base 1, and a damper 17 is provided in the inner cavity of the pressing seat 16. A pressing platform 18 is fixedly connected to the top of the damper 17, and a protrusion 19 is provided on the side wall of the pressing platform 18. The pressing platform 18 is slidably connected to the pressing seat 16 through a buffer rod 20, and the buffer rod 20 is symmetrically distributed on both sides of the bottom of the pressing platform 18. A buffer rod 20 is fixedly installed on one side of the bottom of the pressing platform 18, and a second spring 21 is sleeved on the outer side of the bottom of the buffer rod 20. One end of the second spring 21 is fixedly connected to one end surface of the buffer rod 20, and the other end is fixedly connected to the bottom of the protrusion extending from the inner cavity of the pressing seat 16. A groove 22 is provided on the inner side wall of the pressing seat 16.

[0026] When the pressing platform 18 moves longitudinally under the action of downward pressure, it will squeeze the damper 17 fixedly connected to the middle of its bottom end and cause it to deform accordingly. At the same time, the pressing platform 18 slides along the groove 22 opened on the inner side wall of the pressing seat 16 through the protrusion 19, which improves the stability of the pressing platform 18 during longitudinal movement. When the pressing platform 18 moves longitudinally, the buffer rod 20 will move longitudinally accordingly. The longitudinal movement of the buffer rod 20 will cause the second spring 21 to deform. The reaction force generated by the deformation of the second spring 21 and the damper 17 can achieve the purpose of buffer protection.

[0027] Specific working principle:

[0028] First, place the lens at the bottom of the adsorption seat 6. Then, release the lateral force applied to the two movable rods 14. The reverse force generated by the deformation of the first spring 15 will cause the movable rods 14 to return to their lateral position, thereby pushing the clamping plate 13 laterally. Combined with the opposing movement of the clamping plates 13 on both sides, the lens can be initially clamped and limited. At this time, the air pump 10 works to draw air through the suction hole 7 at the bottom of the adsorption seat 6. The air then passes through the filter cotton adsorption screen 11 in the inner cavity of the guide frame 9 to achieve simple filtration and purification. The drawn air is then discharged through the air outlet 8. At the same time, under the action of negative pressure, the lens will be tightly attached to the bottom of the adsorption seat 6, thereby ensuring the stability of the lens during subsequent handling and preventing the lens from falling off. During the pressing, the cylinder 3 works to push longitudinally. The lifting seat 4 allows the lens to move longitudinally by pushing the adsorption seat 6, facilitating subsequent pressing. The longitudinal movement of the lifting seat 4 causes the guide rod 5 to move longitudinally along the top frame 2, improving stability during this process. When the pressing table 18 moves longitudinally under downward pressure, it squeezes the damper 17 fixedly connected to its bottom center, causing it to deform. Simultaneously, the pressing table 18 slides along the groove 22 on the inner wall of the pressing seat 16 via the protrusion 19, further enhancing stability during longitudinal movement. The longitudinal movement of the pressing table 18 also causes the buffer rod 20 to move longitudinally, which in turn deforms the second spring 21. The combined reaction force from the deformation of the second spring 21 and the damper 17 provides buffering protection.
