Description

Technical Field

[0001] The utility model relates to the technical field of optical communication, in particular to an automatic crimping device for a quick connector assembly. Background Art

[0002] like Figure 1 As shown, a quick connector assembly includes a customized plastic assembly 101 and a standard ceramic ferrule 102. When assembling the plastic assembly and the standard ceramic ferrule, the ceramic ferrule needs to be crimped and assembled in the plastic assembly. In order to ensure the tightness of the assembly after crimping, the outer diameter of the ceramic ferrule is made slightly larger than the diameter of the crimping hole of the plastic assembly during processing and manufacturing. In existing operations, crimping is usually performed manually, and such an operation method is prone to the following problems: 1. The force when assembling and pressing the standard ceramic ferrule is difficult to control, and there is a risk of not crimping in place or using too much force to crack the plastic assembly, resulting in an increased scrap rate; 2. Manual operation has problems such as poor product consistency and low assembly efficiency; 3. Manual operation is labor-intensive.

[0003] Therefore, how to design an automatic crimping device for a quick connector assembly with a simpler and more reasonable structural design, which can better ensure the assembly quality and improve the efficiency of the device, has become a technical problem to be solved by those skilled in the art. Utility Model Content

[0004] In view of the above-mentioned defects of the prior art, the technical problem to be solved by the present invention is how to design an automatic crimping device for a quick connector assembly which has a simpler and more reasonable structural design, can better ensure the assembly quality, and can better improve the efficiency of the device.

[0005] To achieve the above-mentioned purpose, the utility model provides an automatic crimping device for a quick connector assembly, including a base plate, a lower module is arranged on the base plate, a lower mold cavity is arranged on the upper surface of the lower module, an upper template is hingedly arranged on one side of the lower module and can be vertically rotatable, an upper mold cavity is arranged on the lower surface of the upper template, and after the upper template is rotated to a horizontal position, the upper template can be fitted on the lower module, and the lower mold cavity and the upper mold cavity are fitted together to form a placement cavity for placing the quick connector assembly, the standard ceramic ferrule of the quick connector assembly on the lower module and the upper template and in the corresponding placement cavity is penetrated outwardly by an ejector hole and is installed with an ejector, and a driving cylinder is installed on the outer end of the corresponding ejector on the base plate, and the working end of the driving cylinder is connected to the outer end of the ejector.

[0006] Thus, when the above device is working, the plastic component and the standard ceramic ferrule are placed in the lower mold cavity, and then the upper mold plate is operated to fit on the lower mold plate, so that the lower mold cavity and the upper mold cavity fit together, and at the same time, the driving cylinder drives the ejector pin to move and push the standard ceramic ferrule to be inserted and fit into the plastic component. The above device can replace the existing manual assembly operation, can better ensure the assembly quality, improve the consistency of assembly, and can better improve the efficiency of the device.

[0007] As an optimization, a mounting groove is provided on the upper end surface of the lower module, a core block is detachably mounted and fixed in the mounting groove by screws, and the lower mold cavity is provided on the core block.

[0008] In this way, the mold core blocks that are most susceptible to wear and damage can be replaced more conveniently and targetedly, thereby better ensuring dimensional accuracy and reducing use costs.

[0009] As an optimization, a mounting block is integrally formed on the lower module and corresponds to the outer side of the ejector hole, and the upper end of the mounting block extends above the upper end surface of the lower module. After the upper template is rotated to a horizontal state, one side surface of the upper template can be in contact with the inner side surface of the mounting block; a guide hole is coaxially arranged on the mounting block and corresponds to the ejector hole, and the outer end of the ejector passes through the guide hole to the outside and is connected to the working end of the driving cylinder.

[0010] In this way, by setting the mounting block, after the upper template is rotated to horizontal, one side of the upper template can be in contact with the inner side of the mounting block, which better defines the position of the upper template and makes the upper template and the lower module better fit together; secondly, it can also guide the ejector pin.

[0011] As an optimization, an intermediate block is connected and fixed to the front end of the cylinder body of the driving cylinder, and the outer end of the intermediate block is connected to the outside of the mounting block by connecting screws.

[0014] In this way, by setting up the support block, the upper template can be installed more conveniently, and by setting up the torsion spring, the upper template can have a tendency to move away from the lower module when not under force, which can make it easier to remove the parts after assembly.

[0015] As an optimization, the middle portion of the upper surface of the support block is protruded upward to form a support portion, and the protrusion is arranged on the support portion.

[0016] In this way, the structural design of the support block is simpler and more reasonable.

[0017] As an optimization, a micro switch is provided on one side of the support block; the micro switch is connected to the electromagnetic reversing valve on the base plate; the electromagnetic reversing valve is connected to the driving cylinder; the micro switch includes a switch body, a horizontal pressure strip is provided above the switch body, the outer end of the pressure strip is hingedly installed on the switch body in a vertically rotatable manner, and the outer end of the pressure strip is connected to the switch operating rod on the switch body; a spring structure is provided in the middle of the switch body and is supported on the lower surface of the pressure strip so that the pressure strip drives the switch operating rod to move upward and puts the micro switch in an open state; a pressure block is protruding outward on one side of the upper template corresponding to the pressure strip, and after the upper template rotates downward, the pressure block can be pressed on the pressure strip, and the pressure strip overcomes the thrust of the spring mechanism and rotates downward, and puts the micro switch in a closed state.

[0018] In this way, when the upper template is rotated downward to cooperate with the lower module, the micro switch can be closed at the same time, so that the magnetic reversing valve connected to it controls the driving cylinder to drive the ejector to push the standard ceramic ferrule to complete the assembly. After the assembly is completed, when taking out the parts, when the upper template is operated to rotate upward, the pressure block on the upper template is separated from the pressure strip, the spring structure drives the pressure strip to rotate and the switch operating rod moves upward and the micro switch is in the open state, and the magnetic reversing valve connected to it controls the driving cylinder to drive the ejector to move back.

[0019] As an optimization, the spring structure includes a coil spring arranged between the pressure block and the switch body, the lower end of the coil spring is sleeved on the matching protrusion on the switch body, and the upper end of the coil spring is sleeved on the boss on the lower surface of the pressure strip.

[0020] In this way, it is more convenient to install and arrange the coil spring, and the coil spring works more reliably and can better avoid being distorted after compression.

[0021] As an optimization, a roller is provided at the end of the pressure strip, and after the upper template is rotated downward, the pressing block can be pressed onto the roller at the end of the pressure strip.

[0022] In this way, by arranging the roller, the pressure strip and the pressure block can be rolled together.

[0023] As an optimization, both sides of the pressure strip end are bent and extended downward to form hinged strips, and each hinged strip is hinged on the switch body through a mounting axis; the middle part of the pressure strip end face is bent and extended inclined downward to form a limit strip.

[0024] In this way, the hinged installation of the pressure strip can be more convenient, and the tilt angle of the pressure strip can be conveniently limited.

[0025] In summary, the above-mentioned device has the characteristics of better ensuring assembly quality and better improving device efficiency; by setting a micro switch and an electromagnetic reversing valve, the use of the entire device can also be more convenient.
