Description

Technical Field

[0001] The present invention relates to the technical field of crimping equipment, in particular to a crimping machine. Background Art

[0002] In the fiber optic connector manufacturing industry, crimping machines are indispensable production equipment. However, due to their usage characteristics (semi-automatic and small operating space), crimping is also the most dangerous position in the fiber optic connector manufacturing process.

[0003] At present, there are two main ways to operate crimping machines in the fiber optic active connector manufacturing industry. The first is crimping without safety protection. When using crimping machines without protective devices, employees' fingers need to be very close to the crimping die sleeve when operating the crimping machines. Once the operator is physically tired or not paying attention, the fingers will be crushed, which cannot guarantee safety and will increase the production fatigue of employees. The second is crimping with safety protection. Using a crimping machine with safety protection devices can ensure production safety. The disadvantage is that the anti-pressure device is too large and the operation method is relatively complicated, which seriously affects production efficiency.

[0004] Based on this, a crimping machine is urgently needed to solve the above-mentioned problems. Summary of the Invention

[0005] Based on the above, the purpose of the present invention is to provide a crimping machine, which prevents the operator's fingers from entering the crimping station, prevents the occurrence of safety accidents, and increases the safety of equipment use; and the anti-crushing baffle has a simple structure, small size, and is easy to use, thereby improving production efficiency.

[0006] To achieve the above object, the present invention adopts the following technical solutions:

[0011] As an optimal technical solution for a crimping machine, the crimping slider assembly includes an upper slider and a lower slider, the upper slider is installed on the upper die sleeve, and the lower slider is installed on the lower die sleeve. When the upper slider abuts against the lower slider, the crimping hole is formed between the upper slider and the lower slider.

[0012] As an optimal technical solution for a crimping machine, the anti-crushing baffle includes a fixed seat and a bending arm, the fixed seat is fixed on the lower die sleeve, the first end of the bending arm is installed on the first end of the fixed seat, and a wire threading hole is formed between the bending arm and the fixed seat.

[0013] As an optimal technical solution of a crimping machine, a wire passing opening is provided between the second end of the bending arm and the second end of the fixing seat, and the optical fiber active connector can pass through the wire passing opening and be placed in the wire threading hole.

[0016] As an optimal technical solution for a crimping machine, positioning grooves are provided on both sides of the lower die sleeve, and the positioning grooves are used to position the fixing seat when installing the anti-crushing baffle.

[0017] As an optimal technical solution for a crimping machine, the anti-crushing baffle is made of stainless steel.

[0018] As an optimal technical solution for a crimping machine, the optical fiber active connector includes a connector and an optical fiber. When crimping the optical fiber active connector, the two anti-crushing baffles, the one closer to the connector, is the first anti-crushing baffle, and the other is the second anti-crushing baffle.

In addition, the terms "first", "second" are only used to distinguish in description, and have no special meaning.

[0033] At present, the operation of the crimping machine equipment in the optical fiber active connector manufacturing industry is mainly divided into two ways, the first way is to crimp without safety protection, using a crimping machine without safety protection device, the employee needs to operate the crimping machine, the fingers need to be very close to the crimping die sleeve, once the operator is physically tired or not concentrated, the fingers will be crushed, which cannot guarantee safety and will increase the fatigue of the employees; the second way is to crimp with safety protection, using a crimping machine with safety protection device, which can ensure production safety, the disadvantage is that the anti-pressure device is too large in size, the operation method is relatively complex, and the production efficiency is seriously affected.

[0034] To solve the above problems, as shown in Figure 1-Figure 3 The present application provides a crimping machine, which comprises a crimping mechanism 1, two anti-injury baffles 2, a pressure column and a base.

[0035] Specifically, a crimping station 133 is provided on the crimping mechanism 1. When the crimping mechanism 1 crimps the optical fiber active connector, a crimping hole is formed at the crimping station 133. A threading hole 21 is provided in the anti-crushing baffle 2. Two anti-crushing baffles 2 are fixed on both sides of the crimping mechanism 1. The threading holes 21 are in the same direction as the crimping holes and have corresponding positions. The optical fiber active connector can be passed through the threading holes 21 of the two anti-crushing baffles 2 and placed on the crimping station 133 between the two threading holes 21. The size of the threading hole 21 is set so that the operator's fingers cannot enter the crimping station 133. In this embodiment, the width of the threading hole 21 in the vertical direction is 10mm-15mm.

[0036] The optical fiber active connector includes a connector and an optical fiber. A clamping assembly is provided on the optical fiber. The clamping assembly, the connector and the optical fiber need to be pre-assembled manually before they can be crimped. The operator inserts the assembled optical fiber active connector into the threading hole 21 of the two anti-crush baffles 2, and at the same time places the optical fiber active connector to be processed on the crimping station 133 between the two threading holes 21. The crimping machine works and crimps the clamping assembly through the crimping mechanism 1 to fix the connector to the optical fiber. During the operator's placement of the optical fiber connector, since the anti-crush baffles 2 are provided on both sides of the crimping mechanism 1, and the width of the anti-crush baffles 2 in the vertical direction is 10mm-15mm, the optical fiber active connector can pass through the threading hole 21 of this size, but the operator's fingers cannot pass through the threading hole 21 of this size to prevent the fingers from entering the crimping station 133. The operation of the operator is restricted, so no safety accidents will occur, which increases the safety of equipment use; and the anti-crushing baffle 2 has a simple structure, a small size, does not take up space, is reasonably designed, and does not affect actual operation.

[0037] More specifically, Figure 2 As shown, the crimping mechanism 1 includes an upper die sleeve 11, a lower die sleeve 12, and a crimping slider assembly 13. The upper die sleeve 11 is mounted on the bottom of the pressurizing column, and the lower die sleeve 12 is mounted on the base. The upper die sleeve 11 is provided with a groove, and the lower die sleeve 12 is provided with a boss. The boss matches the groove and assists in positioning the upper and lower die sleeves 11, 12. The crimping slider assembly 13 is mounted between the upper and lower die sleeves 11, 12, and the crimping station 133 is located on the crimping slider assembly 13. The crimping slider assembly 13 includes an upper slider 131 and a lower slider 132. The upper slider 131 is installed on the upper die sleeve 11, and the lower slider 132 is installed on the lower die sleeve 12. Under the action of the pressure column, the upper die sleeve 11 moves downward, and the upper die sleeve 11 abuts against the lower die sleeve 12. Through the cooperation of the groove of the upper die sleeve 11 and the boss of the lower die sleeve 12, the upper die sleeve 11 and the lower die sleeve 12 are stably abutted. At the same time, the upper slider 131 abuts against the lower slider 132, and a crimping hole is formed between the upper slider 131 and the lower slider 132.

[0038] Furthermore, the anti-crushing baffle 2 includes a fixing seat 22 and a bending arm 23, wherein the fixing seat 22 is fixed on the lower mold sleeve 12, the first end of the bending arm 23 is installed on the first end of the fixing seat 22, and a threading hole 21 is formed between the bending arm 23 and the fixing seat 22.

[0039] Preferably, since the optical fiber active connector is pre-assembled by the operator before crimping, the axial distance between the two threading holes 21 is relatively long, and two anti-crush baffles 2 are provided along the direction of the threading hole 21, which makes operation difficult and inefficient. In order to improve work efficiency, a wire passing opening 24 is provided between the second end of the bending arm 23 and the second end of the fixing seat 22, and the wire passing opening 24 is connected to the threading hole 21. When the upper slider 131 and the lower slider 132 are not in contact, the operator can pass the optical fiber active connector along the radial direction of the threading hole 21 through the wire passing opening 24 of the two anti-crush baffles 2 and place it in the threading hole 21, and at the same time place it on the crimping station 133, which is simple to operate and improves work efficiency.

[0040] It is further preferred that, since the existing anti-pressure device is too large, employees cannot visually monitor the product during operation, product quality cannot be effectively controlled, and the operation method is relatively complicated, which seriously affects production efficiency. To solve this problem, in this embodiment, the thickness of the bending arm 23 is less than the thickness of the fixed seat 22, and the bending arm 23 is installed on the top surface of the fixed seat 22 and is located on the side away from the crimping mechanism 1, so that a gap is formed between the bending arm 23 and the upper die sleeve 11. On the one hand, the operator can visually monitor the crimping condition of the product through the gap, improve product quality, and at the same time improve product crimping efficiency. On the other hand, when the upper die sleeve 11 moves downward, friction between the upper die sleeve 11 and the anti-crushing baffle 2 is prevented, which damages the crimping machine or the anti-crushing baffle 2, thereby increasing the service life of the crimping machine. Furthermore, the raw material cost of the anti-crushing baffle 2 is reduced, the production cost is reduced, and its weight is reduced, which is convenient for assembly.

[0041] When crimping a fiber optic connector, the two anti-crush plates 2, located closer to the connector, are the first anti-crush plate 201 and the second anti-crush plate 202. The thickness of the first anti-crush plate 201 is greater than that of the second anti-crush plate 202. In this embodiment, the fixing base 22 of the first anti-crush plate 201 is 8 mm thick, and the bending arm 23 is 2 mm thick. This creates a 6 mm gap between the bending arm 23 and the upper die sleeve 11. This gap allows the operator to observe the placement and crimping of the fiber optic connector, improving the crimping quality of the product. The second anti-crush plate 202, however, is only used to restrict the operator's fingers from entering the crimping slider. Therefore, its thickness can be smaller than that of the first anti-crush plate 201, facilitating adjustment of the fiber optic connector's position and reducing material costs. In this embodiment, the fixing base 22 of the second anti-crush plate 202 is 4 mm thick, and the bending arm 23 is 1.5 mm thick. Other thicknesses are possible in other embodiments.

[0042] Preferably, two crimping stations 133 are provided in the crimping slider assembly 13, and two positioning bosses 211 corresponding to the two crimping stations 133 are also provided in the threading hole 21 of the first anti-crush baffle 201. When the optical fiber active connector is inserted into the threading hole 21, the side wall of the connector abuts against the positioning boss 211. At this time, the clamping assembly of the optical fiber active connector is placed in the preset crimping station 133, and the positioning boss 211 improves the crimping quality and production efficiency of the product.

[0043] Furthermore, the crimping machine includes bolts. The fixing base 22 is provided with a strip-shaped hole 25, and the lower die sleeve 12 is provided with a threaded hole 121. The bolts can be inserted into the strip-shaped hole 25 and threadedly connected to the threaded hole 121 of the lower die sleeve 12. The heads of the bolts abut the outer surface of the fixing base 22 on the side away from the lower die sleeve 12, thereby securing the anti-crushing shield 2 to the lower die sleeve 12. In this embodiment, two threaded holes 121 are provided on both sides of the lower die sleeve 12, and each anti-crushing shield 2 is secured by two bolts, improving its stability. Furthermore, the bolts can slide within the strip-shaped holes 25, facilitating adjustment of the position of the anti-crushing shield 2 and the position of the positioning boss 211 relative to the crimping station 133, facilitating assembly. Preferably, positioning grooves 122 are provided on both sides of the lower die sleeve 12. These positioning grooves 122 are used to position the fixing base 22 during installation, facilitating assembly of the anti-crushing shield 2. In this embodiment, the width of the strip-shaped hole 25 is 3.5 mm. The bolts are φ3 mm bolts.

[0044] Preferably, the anti-crushing baffle 2 is made of stainless steel, which has high strength and is not easy to rust, thereby increasing the service life of the anti-crushing baffle 2. Moreover, the anti-crushing baffle 2 is easy to process and has low cost, and can be used in the optical fiber connector manufacturing industry, with strong applicability.

[0045] At present, the protective devices commonly used in the market are large in size and complicated to operate, which seriously affects production efficiency. The specific structure and process are as follows: the lower slider is installed on the slider plate, and a slide rail is set at the bottom of the slider plate. The height of the slider plate and the slide rail is adjusted to meet the height requirements of the crimping station. The slider plate is slid out of the crimping station along the slide rail. Then the operator pre-assembles the optical fiber active connector and places it on the lower slider on the slider plate. The slider plate then carries the optical fiber active connector and moves it along the slide rail to the crimping station. Finally, the optical fiber active connector is crimped. Some protective equipment also comes with a fixing jig to prevent the optical fiber active connector from slipping during the movement and crimping process. The existing technology has a complex structure, cumbersome operation process, and low production efficiency.

[0046] Based on this, in this embodiment, a crimping process is also provided, which is applicable to the crimping machine to reduce safety hazards of operators and increase the service life of the crimping machine, thereby improving the crimping quality of the optical fiber active connector. The crimping process steps are as follows:

[0047] S1. Check the status of each component on the crimping machine: The crimping machine needs to be checked before use. The oil pressure in the pressurized column is within the safe range, the air pressure is within 0.4 MPa-0.6 MPa, and the counter and timer can be used normally.

[0048] S2. Assemble the crimping mechanism 1: Use a hexagonal tool to screw the upper die sleeve 11 and the lower die sleeve 12 into the pressurizing column and base of the crimping machine respectively, and adjust the position until the upper die sleeve 11 and the lower die sleeve 12 fit together perfectly during crimping.

[0049] According to the model of the optical fiber active connector, the corresponding upper slider 131 and lower slider 132 are selected and slid into the upper mold sleeve 11 and the lower mold sleeve 12 respectively along the horizontal direction.

[0050] S3. Install the anti-crushing baffles 2 on the crimping mechanism 1: Place two anti-crushing baffles 2 on both sides of the lower die sleeve 12 and fix them with four φ3 bolts.

[0051] S4. Check the assembly quality of the pre-assembled optical fiber connector: Check the pre-assembled optical fiber connector in the previous process to see if the optical fiber, connector and pressing components are pre-assembled properly.

[0052] S5. Place the pre-assembled optical fiber connector on the crimping station 133 and clamp the connector and the optical fiber tail with both hands.

[0053] S6. Crimping mechanism 1 crimps the optical fiber connector: After the optical fiber connector to be crimped is placed, step on the crimping machine once or twice to perform crimping.

[0054] S7. Place the qualified products on the turnover tray and pass them to the next process.

[0055] When crimping, the crimping machine in this embodiment only needs to place the pre-assembled optical fiber active connector directly on the crimping station 133 for crimping. Compared with the crimping process of the crimping machine with protective devices in the prior art, it has been verified through actual on-site production operations that the production efficiency is increased by 40%, and it also has the effect of preventing crush injuries.

[0056] Furthermore, during actual production operations, the crimping slider assembly 13 needs to be adaptively replaced and adjusted according to the different models of optical fiber active connectors in production. On average, the crimping slider assembly 13 needs to be replaced twice a day. The replacement method in the prior art is relatively complicated. It is necessary to remove the upper slider from the upper mold sleeve and the lower slider from the slider plate. After the replacement is completed, the relative positions of the upper and lower sliders need to be re-adjusted. Each replacement of the crimping slider takes more than 20 minutes. On average, it takes more than 40 minutes to replace the crimping slider every day, which wastes manpower and production time and is inefficient. In this embodiment, when replacing different crimping slider assemblies 13, since the anti-compression baffle 2 is fixed on the lower mold sleeve 12, it does not affect the replacement operation of the crimping slider assembly 13. The upper slider 131 is directly replaced from the upper mold sleeve 11, and the lower slider 132 is replaced from the lower mold sleeve 12. The operation is simple, and the shortest replacement time is only 2 minutes, which greatly improves the replacement efficiency of the crimping slider assembly 13.

Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and that various obvious changes, readjustments, and substitutions can be made by those skilled in the art without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments and may include many other equivalent embodiments without departing from the concept of the present invention. The scope of the present invention is determined by the scope of the appended claims.
