Description
Technical Field
[0001] This utility model relates to the field of connectors, and in particular to a pre-assembly tool for a micro connector matrix. Background Technology
[0002] During the assembly process of miniature connectors, steps such as crimping, assembly, and riveting are usually required, all of which necessitate the correct movement of the parts to the assembly operation area.
[0003] The commonly used feeding method is:
[0004] 1. Manual loading: Parts are placed into the assembly area one by one using tweezers and other tools. This method relies on the workers' manual skills. When a product with 50 to 100 micro-guide needles to be installed on an insulating board is encountered, a worker can only produce a few products a day under a microscope. At the same time, the defect rate of the workpiece is high, which is time-consuming and labor-intensive, and the product is not competitive at all.
[0005] 2. Automated feeding can be achieved through automated equipment, such as vision robots combined with flexible vibratory feeders, or customized XY mechanisms for vibratory feeder flow channels. However, this method involves significant equipment investment and a long development cycle, and its applicability is limited in today's market environment of small-batch, multi-variety production. Often, by the time the developed production equipment is in place, the product's optimal life cycle has passed. Furthermore, the invested equipment is not compatible with other products. To address these issues, we propose a miniature connector matrix pre-assembly tool. Utility Model Content
[0006] The purpose of this invention is to provide a pre-assembly tool for a miniature connector matrix, which has the advantages of fast assembly speed, short tool development cycle, low tool manufacturing cost, and the ability to achieve free positioning of parts, orientation recognition, and small modularization.
[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a micro connector matrix pre-assembly tool, including a fixed frame, a differential screen slidably connected to the inner wall of the fixed frame, a tension spring fixedly connected between the inner wall of the differential screen and the inner wall of the fixed frame by a spring fastener, a laser steel mesh bolted to the inner wall of the fixed frame and located at the bottom of the differential screen, a microchannel guide plate bolted to the bottom of the fixed frame, a micropore funnel bolted to the bottom of the microchannel guide plate, an insulator screen plate provided at the bottom of the micropore funnel, and a bracket provided between the insulator screen plate and the micropore funnel.
[0008] Using the above technical solution, by placing the guide pin part into the tool and gently shaking it, the part will fall into the matrix groove until all the grooves are filled. Pressing the differential screen part will cause it to pass through the laser steel mesh. The part will only fall in the preset direction and enter the microchannel guide plate. The part will slide into the micro-hole funnel according to the designed channel, and then enter the bracket and insulator screen plate through the micro-hole funnel. The bracket can be removed and directly delivered to the assembly station. The assembly speed is fast, the tool development cycle is short, the tool manufacturing cost is low, and it can realize the free positioning of parts, orientation recognition, and small modularization.
[0009] The present invention is further configured such that: a slider is bolted to the surface of the differential screen, and a groove is slidably connected to the surface of the slider, and the groove is formed on the inner wall of the fixed frame.
[0010] By adopting the above technical solution, and by setting up sliders and chutes, differential screen deviation is prevented and stability is improved.
[0011] The present invention is further configured such that a pressing block is bolted to the surface of the differential screen.
[0012] By adopting the above technical solution, the differential screen can be easily moved by setting up a pressing block.
[0013] The present invention is further configured such that the flow channel of the microchannel guide plate has a structure that is larger at the top and smaller at the bottom.
[0014] By adopting the above technical solution, the flow channel of the microchannel guide plate is set with a structure that is larger at the top and smaller at the bottom, which limits the width of the part, reduces the possibility of the part rolling inside, and maintains the correct orientation of the part.
[0015] In summary, this utility model has the following beneficial effects:
[0016] This invention involves placing the guide pin part into the tool and gently shaking it. The part will fall into the matrix grooves until all grooves are filled. Pressing the differential screen part will cause it to pass through the laser steel mesh. The part will only fall in a preset direction and enter the microchannel guide plate. The part will slide into the micro-hole funnel according to the designed channel, and then enter the bracket and insulator screen plate through the micro-hole funnel. The bracket can be removed and directly delivered to the assembly station. The assembly speed is fast, the tool development cycle is short, the tool manufacturing cost is low, and it can realize the free positioning of parts, direction recognition, and small modularization.

[0023] The present invention will be further described in detail below with reference to the accompanying drawings.
[0024] Example 1:
[0025] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A pre-assembly tool for a micro connector matrix includes a fixed frame 1. A differential screen 2 is slidably connected to the inner wall of the fixed frame 1. A tension spring 3 is fixedly connected between the inner wall of the differential screen 2 and the inner wall of the fixed frame 1 via a spring fastener. A laser steel mesh 4 is bolted to the inner wall of the fixed frame 1, and the laser steel mesh 4 is located at the bottom of the differential screen 2. A microchannel guide plate 5 is bolted to the bottom of the fixed frame 1. A micropore funnel 6 is bolted to the bottom of the microchannel guide plate 5. An insulator screen plate 7 is provided at the bottom of the micropore funnel 6. An insulating screen plate 7 is provided between the insulator screen plate 7 and the micropore funnel 6. Equipped with a bracket 8, by placing the guide pin part into the tool and gently shaking it, the part will fall into the matrix groove until all grooves are filled. Pressing the differential screen 2 will cause the part to pass through the laser steel mesh 4. The part will only fall in the preset direction and fall into the microchannel guide plate 5. The part will slide into the microporous funnel 6 according to the designed channel, and then enter the bracket 8 and the insulator screen plate 7 through the microporous funnel 6. The bracket 8 can be removed and directly delivered to the assembly station. The assembly speed is fast, the tool development cycle is short, the tool manufacturing cost is low, and it can realize the free positioning of parts, orientation recognition, and small modularization.
[0026] refer to Figure 4 A slider 9 is bolted to the surface of the differential screen 2, and a groove 10 is slidably connected to the surface of the slider 9. The groove 10 is opened on the inner wall of the fixed frame 1. By setting the slider 9 and the groove 10, the differential screen 2 is prevented from shifting and the stability is improved.
[0027] refer to Figure 2 and Figure 5 The differential screen 2 is bolted with a pressing block 11, which facilitates the movement of the differential screen 2.
[0028] refer to Figure 4 The flow channel of the microchannel guide plate 5 has a structure that is larger at the top and smaller at the bottom. By setting the flow channel of the microchannel guide plate 5 to have a structure that is larger at the top and smaller at the bottom, the width of the part is limited, the possibility of the part rolling inside is reduced, and the correct orientation of the part is maintained.
[0029] Brief Description of Usage: This design tool employs two processing methods: 1. FDM 3D printer, with a printing model accuracy greater than ±0.1mm; 2. Laser cutting, with a cutting model accuracy of approximately ±0.01mm. Combining these two methods, ordinary structural parts are 3D printed, while high-precision parts are laser cut. Except for the laser screen, all other parts of the tool are 3D printed, significantly reducing processing costs. When the guide pin part is placed inside the tool, the differential screen 2 is initially closed. Gently shaking the tool will cause the part to fall into the matrix grooves of the differential screen 2 until all grooves are filled. The differential structure at both ends of the part is specifically designed with grids that allow the part to fall only from a specific direction. For any extra parts, the tool has a pre-stored area. Ensure that there is only one part in each groove. Press the pressing block 11 to move the differential screen 2. Since the rectangular groove of the differential screen 2 and the groove of the laser steel mesh 4 are misaligned, the movement of the differential screen 2 aligns the grooves, and the part will pass through the laser steel mesh 4. The laser steel mesh 4 is specially designed to ensure that the central conductor can only fall in one direction, and the part will only fall in the preset direction. After releasing the hand, the differential screen 2 closes under the action of the tension spring 3, and the part falls into the microchannel guide plate 5. The part will slide to the preset position according to the designed channel, and fall into the insulator screen plate 7 through the micro-hole funnel 6. At this time, the positioning of the batch of parts is completed. Remove the bracket 8 and proceed to the next process.
[0030] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
