Description

Technical Field

[0001] This invention relates to the field of automated conveying and feeding equipment, specifically an automated needle and thread feeding device. Background Technology

[0002] Wire probes are miniature test probes made of thin, long tungsten steel wire as the main body, with an insulating layer and gold-plated tips. In fields such as semiconductor testing, PCB testing, and ICT in-circuit testing, test probes serve as critical signal transmission components, and their assembly accuracy directly affects the stability of test results and their service life. Current probe assembly methods mostly rely on manual or semi-automatic equipment. Operators insert scattered probes one by one into the needle sleeves of a fixture. Due to the small diameter and strict length tolerances of the probes, manual operation suffers from low efficiency, missed insertions, and misaligned insertions. Furthermore, during feeding and conveying, suction methods can easily cause wire probes to fall off, while clamping methods can easily cause them to bend and be damaged.

This invention integrates a material tray area, a feeding device, a feeding component, an automatic screw fastening machine, and a clamping conveyor line, realizing fully automated operation of the entire process of thread needles from feeding and testing to clamping. It replaces the traditional manual insertion method, avoids problems such as missing insertion or misaligned insertion, greatly improves production efficiency, and reduces labor costs.

[0043] 2. In this invention, the clamping component in the feeding assembly uses a flexible part that cooperates with the adsorption hole. When clamping the needle, it is first initially clamped by negative pressure adsorption, and then clamped by the deformation of the flexible part. This avoids the problems of needle bending and damage caused by traditional clamping methods or needle falling off by adsorption methods. It effectively protects the structural integrity of the needle. Furthermore, when the flexible part deforms and clamps, the negative pressure adsorption stops, saving air source consumption and reducing overall energy consumption. Attached Figure Description

[0050] Reference Figures 1-5 This invention provides a technical solution: an automated needle feeding device, comprising:

[0051] The base 1 has a material tray area 2 fixed on its upper surface. A material tray 21 is placed on the material tray area 2, and multiple needles 12 are arranged in an orderly manner in the material tray 21.

[0052] The detection device 3 is set on the base 1 and includes at least a size detection device and a position detection device. The size detection device is used to detect the size of the needle 12 and the position detection device is used to detect the position of the needle 12 when it is being fed.

[0053] Material box 4 is fixed on the base 1 and located between the size detection device and the position detection device;

[0054] The feeding device 5 is fixed on the base 1;

[0055] The feeding component 6 is fixed at the output end of the feeding device 5;

[0056] The automatic screw fastening machine 7 is fixed on the base 1 and is fed by the screw feeder 8 and the clamp feeder 10;

[0057] The positioning detector 9 is fixed on the base 1 and located at the working position of the automatic screw fastening machine 7, and is used to detect the placement status of the needle 12.

[0058] The fixture conveyor line 11 is located on one side of the base 1 and is used to convey the fixtures that have been loaded to the next process.

[0059] It should be noted that the feeding device 5 can be a robotic arm, which facilitates the movement and feeding of the feeding component 6. When the automatic screw fastening machine 7 is working, the clamp is first placed on the slide table, and then the slide table carries the clamp to the working position. At this time, the position detector 9 can detect the needle 12 placed on the clamp, thereby determining whether the needle 12 is placed in place. The automatic screw fastening machine 7 is an existing device, and its specific structure will not be described in detail here.

[0060] In this embodiment, the feeding component 6 includes:

[0061] The connecting rod 61 has its upper end fixed to the output end of the feeding device 5;

[0062] The fixing plate 62 is fixed to the lower end of the connecting rod 61;

[0063] The rotating cylinder 63 is fixed to one side of the fixed plate 62;

[0064] Turntable 64 is fixed at the output end of the rotating cylinder 63;

[0065] Multiple positioning plates 65 are configured and evenly distributed around the circumference of the turntable 64;

[0066] The gas supply component 66 is rotatably mounted on the turntable 64 and is connected to the gas source equipment via a gas supply nozzle 67 and a pipeline.

[0067] Multiple clamping components 68 are configured and are respectively disposed through multiple positioning plates 65.

[0068] In other words, multiple clamping components 68 can achieve continuous operation at multiple stations. The rotating cylinder 63 drives the turntable 64 to send the clamping components 68 to the testing, assembly and other stations in sequence, thereby improving cycle efficiency and reducing idle travel time.

[0069] In a preferred embodiment, the gas supply assembly 66 includes;

[0070] The fixed chamber 661 is rotatably mounted on the turntable 64 and is fixed to the connecting rod 61 by an L-bracket (not shown in the figure);

[0071] The rotating ring 663 is rotatably mounted on the outer wall of the fixed chamber 661;

[0072] Multiple connecting holes 664 are configured and arranged circumferentially on the rotating ring 663, corresponding one-to-one with the multiple clamping components 68.

[0073] Preferably, an air supply hole 662 is provided vertically below the fixed chamber 661. When the connecting hole 664 corresponds to the air supply hole 662, the fixed chamber 661 is connected to the clamping assembly 68.

[0074] The system enables dynamic air supply switching through an air supply hole 662, ensuring that only the clamping component 68 at a specific station (such as the loading station) receives air during the rotation of the turntable 64, while the air supply to other stations is disconnected, thus avoiding malfunctions and saving energy.

[0075] It should be noted that the length of the L-bracket is greater than the length of the clamping assembly 68 to avoid affecting the rotation and switching of the clamping assembly 68.

[0076] In a preferred embodiment, the clamping assembly 68 includes:

[0077] A connecting post 681 is disposed through the positioning plate 65;

[0078] The sliding column 682 is slidably disposed within the connecting column 681;

[0079] An ejector assembly is disposed within the connecting post 681 and above the sliding post 682, and a pressing spring 685 is provided between the ejector assembly and the sliding post 682;

[0080] A flexible component is disposed within the sliding column 682.

[0081] In addition, the telescopic structure of the sliding column 682 not only provides a buffer stroke when clamping the needle 12 to avoid damage to the needle from rigid impact, but also provides driving force to the flexible component, causing the flexible component to slide out.

[0082] Preferably, the ejection component includes:

[0083] A fixed plate 683 is fixed inside the connecting column 681 and located above the sliding column 682. The fixed plate 683 has a plurality of ventilation holes.

[0084] The ejector pin 684 has its upper end threadedly connected to the center of the fixed plate 683, and its lower end extends into the sliding column 682.

[0085] In other words, the position of the ejector pin 684 can be adjusted by the threaded connection of the ejector pin 684, thereby adjusting the sliding distance of the sliding column 682 and adjusting the buffer stroke.

[0086] In a preferred embodiment, the flexible component includes:

[0087] The limiting plate 688 is fixed inside the sliding column 682 and has multiple ventilation holes on it.

[0088] A sliding disk 686 is slidably disposed within the sliding column 682 and located above the limiting disk 688. The sliding disk 686 has multiple ventilation holes and a return spring 689 is provided between it and the limiting disk 688.

[0089] The sliding member 687 is fixed below the sliding disk 686 and slidably connected to the limiting disk 688;

[0090] Pull plate 690 is fixed to the lower end face of the slider 687;

[0091] The flexible component 691 is fixed below the sliding column 682 and its middle position is fixedly connected to the pull plate 690.

[0092] In other words, when the sliding column 682 slides upward by pressing, the ejector pin 684 pushes out the sliding plate 686, causing the pull plate 690 to push out the flexible part 691, forming an arc-shaped suction surface to perform suction on the needle 12. Afterwards, when the feeding device 5 drives the feeding component 6 away from the material tray 21, the sliding column 682 is reset by the pressing spring 685, and the sliding plate 686 is reset by the reset spring 689. At this time, the pull plate 690 pulls the arc-shaped chamber of the flexible part 691 to deform, thereby wrapping and clamping the needle 12. Then the air source is disconnected to complete the clamping operation.

[0093] In addition, the flexible component 691 and the pull plate 690 have arc-shaped compartments at corresponding positions, and the arc-shaped compartments have multiple adsorption holes.

[0094] The arc-shaped compartment facilitates the adsorption and clamping of the needle 12, and the needle can be adsorbed through the adsorption hole to form a preliminary clamping. When the needle 12 is placed into the clamp, the sliding column 682 first slides to push the pull plate 690 out of the flexible part 691. Then, gas can be introduced into the adsorption hole to blow air, so as to prevent the needle 12 from sticking to the flexible part 691 and make it easy to detach.

[0095] In practice:

[0096] S1: During the feeding and needle removal stage, the feeding device 5 drives the feeding component 6 to move above the material tray 21. Then, the feeding device 5 drives the feeding component 6 to move down, so that the flexible part 691 contacts the needle 12. At this time, the needle 12 is stably adsorbed by negative pressure to achieve initial clamping.

[0097] S2: Flexible clamping. The feeding device 5 drives the feeding component 6 to move upward. The sliding plate 686 is reset by the reset spring 689 and pulls the flexible part 691 to deform, thereby forming a wrapping clamping on the needle 12 to ensure that the needle is stably fixed. At this time, the air supply component 66 interrupts the air source and stops the negative pressure adsorption. The clamping is maintained only by the deformation of the flexible part, reducing the consumption of air source.

[0098] S3: Size and position detection. The feeding device 5 sends the needle 12 to the size detection device and the position detection device in sequence. The size detection device is used to determine whether the length, diameter and other dimensions of the needle meet the standard. The position detection device is used to confirm whether the posture of the needle in the clamping assembly is correct. Defective products are placed in the material box 4.

[0099] S4: Clamping and fastening. The qualified needle 12 is conveyed to the working position of the automatic screw fastening machine 7. The clamp is manually placed on the automatic screw fastening machine 7. Then the position detector 9 checks whether the clamp is placed in place and the position of the needle 12. After confirming that there is no error, the automatic screw fastening machine 7 is fed by the screw feeder 8 to complete the locking and fixing of the needle and the clamp.

[0100] S5: Finished product conveying. The assembled fixture is conveyed to the next process by the fixture conveyor line 11. At the same time, the feeding device 5 is reset and enters the next cycle.

[0101] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
