Description

Technical Field

[0001] The utility model relates to the technical field of rubber plug piercing, in particular to a rubber plug piercing fixture. Background Art

[0002] A rubber plug piercing fixture is a specially designed tool used in the fields of electronic manufacturing, electrical installation or other related industries to assist wires, cables or other types of wire harnesses in passing through rubber plugs (also known as insulating plugs or protective plugs). Rubber plugs are usually used to protect the ends of wires, provide electrical insulation, or in some cases, serve as mechanical protection.

[0003] Currently, the existing rubber plug piercing fixtures cannot accurately monitor the position of the rubber plug during the process of threading the wire harness through the rubber plug and automatically lock and fix the rubber plug, resulting in a decrease in the stability of the rubber plug, thereby increasing the operation time and reducing the work efficiency, and affecting the market competitiveness of the product. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the shortcomings in the existing technology that it is impossible to accurately monitor the position of the rubber plug during the process of threading the wire harness through the rubber plug and automatically lock and fix the rubber plug, resulting in a decrease in the stability of the rubber plug, thereby reducing the work efficiency and market competitiveness, and a rubber plug piercing fixture is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] The rubber plug piercing fixture includes:

[0007] A fixture base, the top of the fixture base is hinged with an upper cover through a hinge, a cylinder lock is embedded at the top of the fixture base, a first micro switch is embedded beside the cylinder lock at the top of the fixture base, a U-shaped groove is opened at the bottom of the fixture base, and ten optical fiber sensors are fixedly arranged on the top wall of the U-shaped groove in a uniform distribution. The cylinder lock is electrically connected to the first micro switch.

[0008] In a possible design, a lock tongue is slidably arranged on one side of the cylinder lock, a lock groove is opened at the top of the upper cover, and the positions of the lock tongue and the lock groove correspond to and match each other.

[0009] In a possible design, a plurality of first rubber plug placement cavities and second rubber plug placement cavities are respectively opened at the top of the fixture base. Through holes are opened at the bottoms of the plurality of first rubber plug placement cavities and second rubber plug placement cavities, and the plurality of through holes are respectively communicated with the ten optical fiber sensors. A pressing plate is fixedly arranged at the bottom of the upper cover, and convex blocks corresponding to the first rubber plug placement cavities and the second rubber plug placement cavities are arranged at the bottom of the pressing plate.

[0010] In a possible design, a second micro switch is embedded on one side of the fixture base where the U-shaped groove is located, and the second micro switch is electrically connected to the cylinder lock.

[0011] In a possible design, the shapes of the first rubber plug placement cavity and the second rubber plug placement cavity are different, and the second rubber plug placement cavity is larger than the first rubber plug placement cavity.

[0012] In a possible design, a cover is detachably arranged outside the cylinder lock at the top of the jig base.

[0013] In a possible design, mounting brackets for facilitating the installation of the jig base are fixedly arranged on both sides of the jig base.

[0014] In this application, when starting to use, first, the jig base is fixed on an appropriate workbench by using the mounting brackets to ensure firmness without shaking. Subsequently, according to the work requirements, different types of rubber plugs are respectively placed into the first rubber plug placement cavity and the second rubber plug placement cavity, and it is ensured that the positions and directions of the inserted rubber plugs conform to the design. At the same time, the first rubber plug placement cavity and the second rubber plug placement cavity can also control the distances between the respective rubber plugs and prevent other-shaped rubber plugs from being inserted. Through the function of shape limitation, the operator can quickly and effectively identify which wire harness and rubber plug are used in a set, and it is not easy to occur the situation that the wire harness penetrates the wrong rubber plug or the rubber plug is placed in the wrong direction, which can effectively save manpower and material resources and reduce operation errors;

[0015] After the rubber plugs are placed into the first rubber plug placement cavity and the second rubber plug placement cavity, the rubber plugs will enter the induction range preset by the fiber optic sensors. At this time, eight fiber optic sensors emit signals. After the operator observes the signals emitted by the fiber optic sensors and confirms that there is no problem, the upper cover is slowly lowered. When the bottom of the upper cover presses the first micro switch above, the first micro switch sends a message to the cylinder lock. At this time, the cylinder lock (the cylinder lock has been connected to the corresponding equipment before the rubber plugs are inserted) is ventilated, so that the cylinder lock pushes the lock tongue out from its interior. When the lock tongue pops out, it inserts into the lock groove on the upper cover, so that the lock tongue is located in the lock groove to press and lock the upper cover. At this time, the cylinder lock firmly locks the lock tongue. After the upper cover is closed, the multiple protrusions on the bottom pressing plate of the upper cover are correspondingly pressed into the corresponding rubber plugs in the first rubber plug placement cavity and the second rubber plug placement cavity, thereby fixing the rubber plugs to prevent the rubber plugs from moving when threading the wire harness. Subsequently, after the operator confirms that the cylinder lock is locked, the wire harness can be passed through the rubber plugs. After the wire harness passes through the jig and passes the remaining two fiber optic sensors, ten fiber optic sensors emit signals simultaneously. Through the set program, after collecting ten signals, the cylinder lock automatically unlocks after a certain time, so that the lock tongue retracts and disengages from the lock groove, and then the upper cover is opened, and the wire harness with the rubber plug inserted is taken out of the jig;

[0016] If it is necessary to unlock the upper cover in the non-automatic mode, the second micro switch can be pressed, and this operation transmits an electrical signal to the cylinder lock to retract the lock tongue, thereby allowing the upper cover to be manually opened.

[0017] The utility model has the following beneficial effects:

[0018] In the utility model, through the limitation of the shapes of the rubber plug placement cavity one and the rubber plug placement cavity two, the inner cavity can be designed according to the shape of the rubber plug, ensuring the placement position and direction of different rubber plugs, controlling the distance between each rubber plug, and preventing rubber plugs of other shapes from being inserted. At the same time, the function of shape limitation enables the operator to quickly and effectively identify which wire harness and rubber plug are used in a set, not easily resulting in the situation of the wire harness being inserted into the wrong rubber plug or the rubber plug being placed in the wrong direction, effectively saving manpower and material resources and reducing operation errors.

[0019] In the utility model, through the setting of ten fiber optic sensors, it can reliably ensure the prevention of the rubber plug not being in place and the wrong direction during the process of the wire harness passing through the rubber plug, thereby improving the product quality reliability and reducing the defective rate in wire harness processing, and thus enhancing the customer competitiveness.

[0020] The cooperation among the ten fiber optic sensors, the micro switch and the cylinder lock in the utility model uses the ten fiber optic sensors to accurately monitor the position of the rubber plug, and cooperates with the linkage mechanism of the first micro switch and the cylinder lock to realize the automatic locking and unlocking process of the upper cover. This not only ensures the stability of the rubber plug during the process of the wire harness passing through, but also significantly saves the operation time through the automated process, improves the work efficiency, provides great convenience for the operator, and at the same time enhances the market competitiveness of the product.

[0028] Referring to Figures 1-4 , the jig includes:

[0029] A jig base 1, on the top of which a top cover 2 is installed by a hinge connection method, so that the top cover 2 can be flexibly opened and closed. A cylinder lock 3 (model number can be: QG16-20) is embedded at the position of the rubber plug placement cavity one 7 and the rubber plug placement cavity two 8 on the top of the jig base 1. The cylinder lock 3 is used to realize the automatic locking and unlocking functions of the top cover 2. Next to the cylinder lock 3, a first micro switch 5 is also embedded on the top of the jig base 1. The first micro switch 5 is used to detect the closed state of the top cover 2 and trigger the action of the cylinder lock 3.

[0030] In order to monitor the placement of the rubber plugs, a U-shaped groove is designed at the bottom of the jig base 1, and ten evenly distributed fiber optic sensors 4 (model number can be: LS12-DS15C1) are fixedly installed on the top wall of the U-shaped groove. These fiber optic sensors 4 are preset with an induction range. When the rubber plugs are correctly placed in the rubber plug placement cavities, they will enter the induction area of the sensors, thereby triggering signal output. The cylinder lock 3 and the first micro switch 5 are electrically connected to achieve signal transmission and control.

[0031] A lock tongue 301 is slidably installed on one side of the cylinder lock 3, and a lock groove 201 is correspondingly opened on the top of the top cover 2. When the cylinder lock 3 is closed and triggers the first micro switch 5 (model number can be: HJ-16), after the cylinder lock 3 receives the signal from the first micro switch 5 and is ventilated, it will push the lock tongue 301 out from its interior until it is inserted into the lock groove 201 of the top cover 2 to achieve firm locking of the top cover 2.

[0032] In order to fix the rubber plugs and prevent them from moving during the wire harness threading, a plurality of rubber plug placement cavities one 7 and rubber plug placement cavities two 8 are respectively opened on the top of the jig base 1. Through holes are provided at the bottoms of the plurality of rubber plug placement cavities one 7 and rubber plug placement cavities two 8, and the through holes are communicated with the fiber optic sensors 4 to ensure that the sensors can accurately sense the in-place situation of the rubber plugs. A pressing plate 9 is fixedly installed at the bottom of the top cover 2, and convex blocks corresponding to the rubber plug placement cavities one 7 and rubber plug placement cavities two 8 are provided at the bottom of the pressing plate 9. When the top cover 2 is closed, the convex blocks will press on the rubber plugs to further fix the rubber plugs.

[0033] To improve the operational flexibility, a second micro switch 6 (model: HJ-16 for example) is also embedded on one side of the U-shaped groove of the fixture base 1. This switch is electrically connected to the cylinder lock 3, allowing the cylinder lock 3 to be manually unlocked when needed, so that the locking tongue 301 retracts, thereby opening the upper cover 2.

[0034] This application can be used in the technical field of rubber plug inserting fixtures, and can also be used in other fields applicable to this application.

[0035] Embodiment 2

In addition, the rubber plug placement cavity 1 7 and the rubber plug placement cavity 2 8 are designed with different shapes, and the size of the rubber plug placement cavity 2 8 is larger than that of the rubber plug placement cavity 1 7. By shape restriction, it is ensured that different types of rubber plugs can be placed in the correct position and direction.

[0037] A detachable cover 10 is also provided on the top of the fixture base 1 outside the cylinder lock 3. This cover 10 can protect the cylinder lock 3 from dust and debris.

[0038] Finally, mounting brackets 11 are fixedly installed on both sides of the fixture base 1. These mounting brackets 11 not only enhance the structural stability of the fixture base 1, but also provide convenient mounting interfaces, enabling the entire fixture to be easily mounted on a workbench or other fixed positions.

[0039] However, as is well known to those skilled in the art, the working principles and wiring methods of the cylinder lock 3, the fiber optic sensor 4, the first micro switch 5, and the second micro switch 6 are common knowledge. They all belong to conventional means or well-known common sense, and will not be elaborated here. Those skilled in the art can make arbitrary selections according to their needs or convenience.
