Description

Technical Field

[0001] The utility model relates to the technical field of gel pen assembly equipment, in particular to a gel pen assembly device with positioning and conveying effects. Background Art

[0002] The assembly of gel pens involves the coordination of various devices. First, the pen barrel is transferred to a conveyor belt, which then gradually moves it to different assembly devices for assembly. Before assembling the back cover of the pen, the refill is first inserted into the pen barrel with a portion left, and then the back cover is hung on the end of the refill. Finally, the back cover and refill are pushed into the pen barrel through a related pushing device. However, during this process, the back cover and the pen barrel are not on the same axis (such as Figure 3 As shown in the figure), it is easy to affect the smoothness of assembly, especially when the refill is thinner, the axis of the back cover and the pen body will differ more, and the assembly effect will be worse. Utility Model Content

[0003] 1. Technical issues to be solved

[0004] In view of the deficiencies in the prior art, the utility model provides a gel pen assembly device with a positioning and conveying effect, which solves the problem that when assembling the back cover of the gel pen, the back cover and the pen holder are not on the same axis, which easily affects the smoothness of assembly.

[0005] (II) Technical solution

[0006] To achieve the above purpose, the utility model is implemented through the following technical solutions: a gel pen assembly device with positioning and conveying effect, including a conveyor belt and a workbench below it, a support frame and a fixed seat are installed on the workbench, a pressing cylinder that can press down and fix the pen holder at the top of the conveyor belt is installed on the support frame, a propulsion cylinder is installed on the fixed seat, a telescopic rod of the propulsion cylinder passes through the fixed seat and is connected to a mounting plate, and a positioning propulsion assembly is fixed on the side of the mounting plate away from the propulsion cylinder;

[0007] The positioning and propulsion assembly includes a sleeve connected to the mounting plate and having an opening at one end, a first annular airbag is bonded to the inner wall of the sleeve away from the opening, an extrusion plate is bonded to the other end of the first airbag, a pull rod is connected to the side wall of the extrusion plate, the end of the pull rod passes through the first airbag and the sleeve and is connected to the fixed seat, an airbag ring for centering and positioning the gel pen accessory is bonded to the inner wall of the sleeve near the opening, the airbag ring is connected to the first airbag through a first conduit, and a pushing block is provided in the sleeve near the airbag ring.

[0008] Furthermore, a second annular airbag is bonded to the side of the pushing block away from the opening of the sleeve, and a fixing plate fixed to the inside of the sleeve is bonded to the other end of the second airbag. A second conduit is connected between the second airbag and the airbag ring. When the airbag ring expands due to the filling of air inside, the centering and positioning operation of the gel pen accessory is also completed. At the same time, the airflow flows into the second airbag through the second conduit. The expanded second airbag can drive the pushing block to move toward the opening of the sleeve until it is flush with the opening end of the sleeve, which is beneficial to extend the pushing distance of the back cover of the gel pen, ensure the assembly effect, and also facilitate the separation of the gel pen from the device, thereby improving the smoothness of assembly.

[0009] Furthermore, a limiting rod is bonded to the side wall of the pushing block, the end of the limiting rod passes through the second airbag and extends to the other side of the fixing plate, and the limiting rod is located at the axis of the sleeve, which can ensure the stability of the movement of the pushing block.

[0010] Furthermore, the first conduit and the second conduit are located on opposite sides of the sleeve, which prolongs the time for the gas in the airbag ring to enter the second airbag, thereby facilitating the expansion of the airbag ring.

[0011] Furthermore, a protective coating is provided on the inner wall of the airbag ring to improve the wear resistance of the airbag ring.

[0012] Furthermore, the extrusion plate is movably installed in the sleeve and can slide along with the deformation of the first airbag.

[0013] (III) Beneficial effects

[0014] The utility model provides a gel pen assembly device with positioning and conveying effect. It has the following beneficial effects:

[0015] 1. In the gel pen assembly device with positioning and conveying effect, when the positioning and propulsion component drives the pen back cover to be conveyed to the pen holder, the first airbag is continuously squeezed, causing the internal gas to enter the airbag ring through the first conduit, and the inner diameter of the expanded airbag ring gradually shrinks and squeezes the pen back cover toward the axis of the pen holder, while clamping the pen back cover and conveying it to the tail end of the pen holder until the assembly is completed. The pen can be self-centered and positioned to avoid affecting the assembly effect due to the pen back cover not being coaxial with the pen holder.

[0016] 2. The gel pen assembly device with positioning and conveying effect, when the airbag ring is expanded due to the filling of air inside, the centering and positioning operation of the gel pen accessories is also completed. At the same time, the airflow flows into the second airbag through the second conduit. The expanded second airbag can drive the push block to move toward the opening of the sleeve until it is flush with the opening end of the sleeve, which is beneficial to extend the pushing distance of the back cover of the gel pen, ensure the assembly effect, and also facilitate the separation of the gel pen from the device, thereby improving the smoothness of assembly.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] The utility model provides a gel pen assembly device with positioning and conveying effect, such as Figure 1-3 As shown, it includes a conveyor belt 2 and a workbench 1 below it, a groove adapted to a gel pen is provided on the top of the conveyor belt 2, the gel pen holder is stuck in the groove and moves with the conveyor belt 2, a support frame and a fixed seat 4 are installed on the workbench 1, a pressing cylinder 3 which can press down and fix the pen holder on the top of the conveyor belt 2 is installed on the support frame, a sensor for detecting the movement state of the gel pen holder is also installed on the support frame, a propulsion cylinder 5 is installed on the fixed seat 4, the pressing cylinder 3 and the propulsion cylinder 5 are both connected with a five-way electromagnetic valve, the electromagnetic valve is connected with an air supply device, a PLC sensor electrically connected with the electromagnetic valve and the sensor is installed on the workbench 1, the telescopic rod of the propulsion cylinder 5 passes through the fixed seat 4 and is connected with a mounting plate 6, a positioning propulsion assembly 7 is fixed on the side of the mounting plate 6 away from the propulsion cylinder 5, and the axis of the positioning propulsion assembly 7 is in the same plane as the axis of the gel pen on the top of the conveyor belt 2;

[0023] The positioning and propulsion assembly 7 includes a sleeve 71 connected to the mounting plate 6 and having an opening at one end. The open end of the sleeve 71 is close to the pen back cover without the pen holder installed. The sleeve 71 can only move as far as the open end close to the pen holder. An annular first airbag 72 is bonded to the inner wall of the sleeve 71 on the side away from the opening. An extrusion plate 73 is bonded to the other end of the first airbag 72. A pull rod 74 is connected to the side wall of the extrusion plate 73. The end of the pull rod 74 passes through the first airbag 72 and the sleeve 71 and is connected to the fixing seat 4. An airbag ring 75 for centering and positioning the gel pen accessories is bonded to the inner wall of the sleeve 71 and close to the opening. The airbag ring 75 is connected to the first airbag 72 through a first conduit. The volume of the bag ring 75 is much smaller than that of the first air bag 72. A pushing block 76 is provided inside the sleeve 71 and near the air bag ring 75. When the rear cover of the pen is assembled to the tail end of the pen shaft, the propulsion cylinder 5 extends to drive the positioning propulsion assembly 7 to move toward the rear cover side of the pen, and the sleeve 71 gradually covers the rear cover of the pen. Since the pull rod 74 fixes the extrusion plate 73, the first air bag 72 is continuously squeezed, causing the internal gas to enter the air bag ring 75 through the first conduit. The inner diameter of the expanded air bag ring 75 gradually shrinks and squeezes the rear cover of the pen toward the axis of the pen shaft. At the same time, the rear cover of the pen is clamped and transported to the tail end of the pen shaft until the assembly is completed. It can be self-centered to avoid the rear cover of the pen affecting the assembly effect due to not being coaxial with the pen shaft.

[0024] Specifically, a ring-shaped second airbag 78 is bonded to the side of the push block 76 away from the opening of the sleeve 71, and a fixing plate 79 fixed to the inside of the sleeve 71 is bonded to the other end of the second airbag 78. A second conduit is connected between the second airbag 78 and the airbag ring 75. When the airbag ring 75 expands due to the filling of air inside, the centering and positioning operation of the gel pen accessory is also completed. At the same time, the airflow flows into the second airbag 78 through the second conduit. The expanded second airbag 78 can drive the push block 76 to move toward the opening of the sleeve 71 until it is flush with the opening end of the sleeve 71, which is beneficial to extend the pushing distance of the back cover of the gel pen, ensure the assembly effect, and also facilitate the separation of the gel pen from the device, thereby improving the smoothness of assembly.

[0025] Specifically, a limiting rod 77 is bonded to the side wall of the push block 76 , and the end of the limiting rod 77 passes through the second airbag 78 and extends to the other side of the fixing plate 79 . The limiting rod 77 is located at the axis of the sleeve 71 , which can ensure the stability of the movement of the push block 76 .

[0026] Specifically, the first conduit and the second conduit are located on opposite sides of the sleeve 71 , which prolongs the time for the gas in the airbag ring 75 to enter the second airbag 78 , thereby facilitating the expansion of the airbag ring 75 .

[0027] Specifically, a protective coating 8 is provided on the inner wall of the airbag ring 75 to improve the wear resistance of the airbag ring 75 .

[0028] Specifically, the extrusion plate 73 is movably installed in the sleeve 71 and can slide along with the deformation of the first airbag 72 .

[0029] Working principle: When in use, when the rear cover is assembled to the rear end of the pen barrel, the propulsion cylinder 5 extends and drives the positioning propulsion assembly 7 to move toward the side of the pen rear cover, and the sleeve 71 gradually covers the pen rear cover. Since the pull rod 74 fixes the extrusion plate 73, the first air bag 72 is continuously squeezed, causing the internal gas to enter the air bag ring 75 through the first conduit. The inner diameter of the expanded air bag ring 75 gradually shrinks and squeezes the pen rear cover toward the axis of the pen barrel, while clamping the pen rear cover and transporting it to the rear end of the pen barrel until the assembly is completed. When the air bag ring 75 expands due to the air filling inside, the centering and positioning operation of the gel pen accessory is also completed. At the same time, the air flow flows into the second air bag 78 through the second conduit. The expanded second air bag 78 can drive the push block 76 to move toward the opening of the sleeve 71 until it is flush with the open end of the sleeve 71, which is beneficial to extend the propulsion distance of the gel pen rear cover, ensure the assembly effect, and also facilitate the separation of the gel pen from the device, thereby improving the smoothness of assembly.
