Description

Technical Field

[0001] This utility model relates to the field of camera component inspection technology, and in particular to a quick-release structure for an adsorption-type suction head. Background Technology

[0002] In automated production and testing equipment, efficient and precise material handling is a key factor in ensuring production efficiency and product quality. Especially in the assembly and testing of precision electronic components such as camera modules, mobile phone lenses, and micro sensors, the parts are small, lightweight, have high surface finish, and are easily contaminated or scratched. Traditional mechanical clamping and handling methods are prone to surface damage or electrostatic contamination due to rigid contact, which seriously affects product yield. Therefore, vacuum adsorption material handling mechanisms are widely used in such scenarios. They achieve non-destructive gripping through flexible contact, improving the stability of operations and product integrity.

[0003] However, existing adsorption structures still have many shortcomings. On the one hand, the suction head is mostly fixed to the metal connecting rod by screws or interference fit, which is cumbersome to disassemble and inconvenient for daily cleaning or replacement. Especially after long-term operation, the plastic suction head is prone to accumulating dust or residue, affecting the adsorption effect and reducing maintenance efficiency.

[0004] On the other hand, in multi-point synchronous adsorption scenarios, if there is a slight height difference between the parts to be picked up or placed, or if there is a flatness error in the carrier, it is difficult for the rigidly connected multiple suction heads to adaptively fit the surface of the parts. This often leads to some suction heads being suspended or uneven pressure, resulting in problems such as missed suction, displacement, or even failure to pick up materials. In addition, there is a lack of buffering mechanism when the suction head contacts the parts, which can easily damage brittle or high-gloss surfaces due to impact, thus restricting the application of the equipment in high-precision and high-cleanliness environments. Utility Model Content

[0005] This utility model provides a quick-release structure for an adsorption suction head, including a back plate. At least six sets of telescopic adsorption components are arrayed on the back plate. The bottom end of each set of telescopic adsorption components is connected to an aluminum alloy head. The lower end face of the aluminum alloy head is provided with four circumferentially distributed grooves. Each groove is embedded with a magnetic strip. A plastic adsorption head is detachably fitted onto the lower outer periphery of the aluminum alloy head. Four magnetic strips are provided at corresponding positions on the upper edge of the plastic adsorption head. The magnetic strips are magnetically attracted to the magnetic strips to achieve quick connection and disassembly of the plastic adsorption head and the aluminum alloy head.

[0006] Preferably, the aluminum alloy head has an air hole inside, which extends from the top to the bottom of the aluminum alloy head, and the upper end of the air hole is connected to the lower end of the telescopic adsorption component.

[0007] Preferably, the plastic adsorption head has four air channels.

[0008] Preferably, the lower side of the aluminum alloy head is provided with a protruding edge, and the plastic adsorption head is sleeved on the outside of the protruding edge.

[0009] Preferably, magnetic sleeves are provided at the four corners of the aluminum alloy head, and magnetic posts are provided at the four corners of the plastic adsorption head. The magnetic posts are inserted into the magnetic sleeves and magnetically connected.

[0010] Preferably, the telescopic adsorption assembly includes a lower fixing sleeve fixed to the back plate, a connecting tube slidably disposed inside the lower fixing sleeve, a second telescopic groove being opened inside the lower end of the connecting tube, the upper end of the second hollow tube being slidably disposed inside the second telescopic groove, and the lower end of the second hollow tube communicating with the air hole.

[0011] Preferably, a second spring is provided inside the second telescopic groove, with the upper end of the second spring connected to the upper wall of the second telescopic groove and the lower end sleeved on the upper end of the second hollow tube.

[0012] Preferably, the upper end of the connecting pipe is connected to a hollow tube, the upper end of the hollow tube is fitted with an upper air pipe, and the lower end of the upper air pipe has an expansion groove, the upper end of the hollow tube sliding in the expansion groove.

[0013] Preferably, a spring is provided inside the telescopic groove, with the upper end of the spring connected to the upper wall of the telescopic groove and the lower end sleeved on the upper end of the hollow tube.

[0014] Preferably, a plurality of upper fixing sleeves are fixedly provided on the back plate, and the upper air pipe is fixedly provided inside the upper fixing sleeves.

[0015] This utility model provides a quick-release structure for an adsorption suction head, which, compared with the prior art, offers the following advantages:

[0016] 1. This utility model features a magnetic stripe 1 installed in the groove on the lower end face of the aluminum alloy head, and a corresponding magnetic stripe 2 installed on the upper edge of the plastic adsorption head. The two are reliably connected by magnetic attraction. The magnetic quick-release structure eliminates the need for screws, clips, or other additional fasteners. Disassembly requires only a small pulling force, facilitating quick cleaning or replacement of easily contaminated or damaged plastic adsorption heads. This significantly improves equipment maintenance efficiency. At the same time, the magnetic connection method ensures the repeatability and positioning accuracy of the assembly, avoids interface wear caused by frequent disassembly and assembly, and extends the service life of the adsorption head assembly. It is particularly suitable for automated handling of precision electronic components such as camera modules, effectively ensuring production continuity and product cleanliness.

[0017] 2. This utility model is equipped with a telescopic adsorption assembly. Each telescopic adsorption assembly includes an upper telescopic unit composed of a connecting tube and a hollow tube, and a lower telescopic unit composed of a hollow tube and a telescopic groove. Springs 1 and 2 are respectively set in the two layers to form a double buffer mechanism. When multiple suction heads contact the parts to be adsorbed at the same time, each telescopic unit can be compressed independently, automatically compensating for inconsistencies caused by differences in the height of the parts surface or errors in the flatness of the installation. This ensures that each adsorption point can be tightly attached to the surface of the parts, effectively avoiding problems such as missed adsorption or insufficient adsorption force. At the same time, the elastic structure plays a buffering role at the moment of contact, preventing hard collisions from damaging the surface of precision parts, improving the safety and reliability of pick-and-place operations, and meeting the needs of high-precision, high-yield automated production.

[0029] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0030] Please refer to Figures 1-8 This utility model embodiment provides an adsorption suction head quick-release structure, including a back plate 1, on which at least six sets of telescopic adsorption components are arranged in an array to achieve multi-point synchronous adsorption and improve material picking stability.

[0031] like Figures 2 to 5 As shown, each set of telescopic adsorption components includes an upper air pipe 4, a connecting pipe 8, a hollow tube 1 7, a hollow tube 2 11, a spring 1 6, and a spring 2 10, forming an elastic telescopic mechanism with dual buffering function.

[0032] Specifically, several upper fixing sleeves 2 are fixedly installed on the back plate 1. The upper end of the upper air pipe 4 is connected to the vacuum generator, and the lower end is inserted into and fixed in the upper fixing sleeve 2 to ensure the air passage is sealed. The lower end of the upper air pipe 4 has a telescopic groove 5. The upper end of the hollow tube 7 is slidably installed in the telescopic groove 5 and can slide up and down in the groove. A spring 6 is installed in the telescopic groove 5. The upper end of the spring 6 is connected to the top wall of the telescopic groove 5, and the lower end is sleeved on the outer periphery of the upper end of the hollow tube 7 to provide elastic buffer for the upper telescopic unit.

[0033] The upper end of the connecting pipe 8 is fixedly connected to the lower end of the hollow pipe 7, and the whole is slidably disposed in the lower fixing sleeve 3, which is fixed below the back plate 1.

[0034] The lower end of the connecting pipe 8 is provided with a telescopic groove 2 9. The upper end of the hollow pipe 2 11 is slidably embedded in the telescopic groove 2 9 to realize a two-stage telescopic movement. The telescopic groove 2 9 is provided with a spring 2 10. The upper end of the spring 2 10 is connected to the top wall of the telescopic groove 2 9, and the lower end is sleeved on the upper end of the hollow pipe 2 11 to provide a second-stage elastic buffer.

[0035] The lower end of the hollow tube 11 is connected to the air hole 13 at the top of the aluminum alloy head 12, so that the vacuum negative pressure is conducted sequentially through the upper air pipe 4 → hollow tube 7 → connecting pipe 8 → hollow tube 11 → air hole 13 to the adsorption end.

[0036] The aluminum alloy head 12 has an axially oriented air hole 13 inside, which extends from the top to the bottom and is used to transmit vacuum negative pressure. The lower end face of the aluminum alloy head 12 has four circumferentially evenly distributed grooves, each groove is embedded with a magnetic strip 15, and a raised edge 14 is provided on the lower outer periphery of the aluminum alloy head 12 for axial positioning and radial limiting of the plastic adsorption head 17.

[0037] The plastic adsorption head 17 has a detachable structure. Four magnetic strips 18 are provided at the corresponding positions on the upper edge of the plastic adsorption head 17. When the plastic adsorption head 17 is fitted onto the outside of the protruding edge 14, the magnetic strips 18 and the magnetic strips 15 in the groove are magnetically adsorbed and connected, completing the quick assembly.

[0038] To enhance connection stability, magnetic sleeves 16 are provided at the four corners of the aluminum alloy head 12, and magnetic posts 19 are provided at the corresponding corners of the plastic adsorption head 17. The magnetic posts 19 can be inserted into the magnetic sleeves 16 and form a magnetic fit to achieve circumferential anti-rotation and multi-point locking, preventing the adsorption head from rotating relative to each other or falling off during operation.

[0039] Furthermore, the plastic adsorption head 17 is provided with four air channels 20. The air channels 20 and the air holes 13 at the bottom of the aluminum alloy head 12 are used to draw a vacuum, ensuring that the vacuum negative pressure can be smoothly transmitted to the adsorption surface to achieve effective adsorption of the workpiece. When drawing a vacuum, the air pressure also acts on the plastic adsorption head 17, improving the stability of the plastic adsorption head 17 during use. When it is necessary to replace or clean the plastic adsorption head 17, the operator only needs to apply a slight pulling force to overcome the magnetic force and remove it as a whole. No tools are required for disassembly, making maintenance convenient.

[0040] In summary, during operation, the upper air pipe 4 is connected to a vacuum source. Negative pressure is conducted through hollow tube 1 7, connecting pipe 8, and hollow tube 2 11 to the air hole 13 of the aluminum alloy head 12, and then acts on the adsorption surface of the plastic adsorption head 17 through the air passage 20. When the adsorption head contacts the workpiece, spring 1 6 and spring 2 10 in the telescopic adsorption assembly are compressed in telescopic groove 1 5 and telescopic groove 2 9 respectively, achieving two-stage independent buffering to adapt to differences in workpiece height and ensure that all adsorption points are tightly attached. After the material is picked up, the vacuum is cut off and the workpiece is released. During maintenance, the plastic adsorption head 17 can be quickly removed for cleaning or replacement. When reinstalling, automatic alignment and firm connection are achieved by the magnetic cooperation of magnetic strip 1 15 and magnetic strip 2 18, and magnetic column 19 and magnetic sleeve 16.

[0041] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
