Description

Technical Field

[0001] The present invention relates to an automatic processing device for the inner cavity of a circular connector housing, and is particularly applicable to the automatic processing of the inner cavity of circular connector housing parts. Background Art

[0002] The housing of an electrical connector refers to the outer shells of plugs and sockets. The function of the outer shell is to protect the internal parts of the electrical connector such as insulators and contacts (including pins and jacks) from being damaged. At the same time, it plays a role in fixing the insulator assembly, and the positioning key grooves on it ensure the positioning of the plug and the socket. To ensure the fixing effect of the housing on the insulator assembly, a snap ring is usually inserted into the snap ring groove of the housing to fix the axial position of the insulating assembly, and a filling adhesive is poured into the gap between the housing and the assembly for rain and dust protection. Before assembly, pretreatment is usually carried out on the inner cavity of the housing, including pouring a layer of adhesive into the snap ring groove to increase the fixing effect of the snap ring, and brushing a primer at the glue pouring position between the insulating assembly and the housing to ensure the adhesion between the inner cavity of the housing and the adhesive. Currently, pouring glue into the snap ring groove and brushing the primer are mainly carried out manually. At present, when most production enterprises assemble the housing, manual operation is used to apply glue to the joint surface of the housing by using a glue applicator stick and forceps. Due to the high precision requirements for production assembly and the lack of special glue application production equipment, it is difficult to accurately control the thickness and width of the glue layer during manual glue application. During installation, there is often excess glue or lack of glue between the housings. When there is excess glue between the housings, it is difficult to clean the excess glue, and a large amount of glue is wasted in production. When there is a lack of glue between the housings, the produced products are judged as unqualified, resulting in great difficulty in training professional technical workers for enterprises, a large demand for technical workers, high labor costs, and an increase in the production cost of products.

[0003] Existing automatic glue application equipment usually requires the setting of a glue application execution device and a workpiece clamping device. The glue application execution device is usually set as brush glue application, or the workpiece can be directly placed in a glue storage box, which is relatively simple and widely used in existing glue applicators. Relatively speaking, the design requirements for the workpiece clamping device are relatively high. Especially for tubular glue application workpieces, it is very difficult to achieve automatic clamping and automatic recycling of the workpiece. Chinese Patent CN105251663B does not perform pretreatment before glue application, which will affect the glue application effect. In view of the above-mentioned many reasons, an automatic glue application device for the housing is designed. Summary of the Invention

For a method invention, specific structural implementation steps, specific data used in each step, etc. should be described; for a product invention, the composition of the structural invention, the static positions and connection relationships between various components, the dynamic action process and working principle should be described and explained in detail with reference to each drawing. The detailed implementation mode should be consistent with the technical solution, but should be more detailed and specific than the content described in the technical solution.

[0051] An automatic device for pre - treatment and glue coating of a housing before gluing in this embodiment, as Figure 14 shown, is used for glue coating treatment of the housing 11. The housing 11 is provided with an inner cavity surface 1101, and the inner cavity surface 1101 is provided with an annular inner cavity groove 1102, and glue needs to be coated at the position of the inner cavity groove 1102.

[0052] An embodiment of the present invention provides an automatic device for pre - treatment and glue coating of a housing before gluing, as Figure 1 shown, including a tray placing mechanism 1, a material detection mechanism 2, a first slide rail module 3, a four - axis robot 4, a plasma treatment mechanism 5, a glue coating mechanism 6, a first base 7, a support frame 8, a second base 9, and a workbench 10.

[0053] The four-axis robot 4 is used to grasp the housing on the tray placing mechanism 1. Meanwhile, the material detection mechanism 2 detects whether the four-axis robot 4 has missed grasping or grasped the housing in the wrong orientation. The four-axis robot 4 removes the defective housing 11 grasped in the wrong orientation and moves the qualified housing 11 to the second base 9, and the second base 9 grips the housing. Driven by the first slide rail module 3, the second base 9 is moved to directly below one side of the support frame 8. Meanwhile, the plasma treatment mechanism 5 is moved to directly above the second base 9 to perform plasma treatment on the housing 11. After that, driven by the first slide rail module 3, the second base 9 is moved to directly below the other side of the support frame 8. Meanwhile, the gluing mechanism 6 is moved to directly above the second base 9 to apply glue to the housing 11. During the plasma treatment and gluing processes, the second base 9 drives the housing 11 to rotate. After the gluing is completed, the four-axis robot 4 grasps the housing 11 on the second base 9 and moves the housing 11 to the first base 7, and the first base 7 moves the housing 11 to the next process.

[0054] As Figure 1 and Figure 2 shown, the tray placing mechanism 1 includes a tray 15, a handle 12, a proximity switch 13, and a first bracket 14. There are a handle 12 and a proximity switch 13 on both sides of the tray 15 respectively. The tray 15 is fixed on the workbench 10 through the first bracket 14. The proximity switch 13 is used to identify whether the tray 15 is placed in the appropriate position; the tray 15 is used to place the housing 11. The tray placing mechanism 1 is fixed on the workbench 10 through the first bracket 14. An operator places the tray 15 filled with the housing 11 on the first bracket 14 through the handle 12, and the proximity switch 13 identifies whether the tray 15 is placed in place.

[0055] As Figure 1 and Figure 3 shown, the material detection mechanism 2 includes a defective product receiving box 21, an infrared detection sensor 22 (i.e., an infrared tester), and a second bracket 23. The infrared detection sensor 22 is placed on the second bracket 23. After the four-axis robot 4 grasps the housing 11 from the tray placing mechanism 1, it tests whether there is a missed grasp or a wrong grasp through the infrared detection sensor 22. If it is grasped in the wrong orientation, the housing 11 is placed into the defective product receiving box 21.

[0056] As Figure 1 and Figure 4 shown, the first slide rail module 3 includes a first servo motor 31, a first slide rail 32, and a first slider 33. The first slide rail 32 is fixed on the workbench 10. The first slider 33 is slidably connected to the first slide rail 32. The first servo motor 31 is fixed at the top of the first slide rail 32, and the first servo motor 31 drives the first slider 33 to move back and forth along the first slide rail 32. Multiple groups of the first slide rail module 3 can be set. In this embodiment, two groups of the first slide rail module 3 are set, and the first slide rails 32 of the two groups of the first slide rail module 3 are parallel to each other.

[0057] As Figure 1, Figure 10 , and Figure 11 As shown in Figure 10 and Figure 11 , the second base 9 includes a fourth bracket fixed to the first slider 33, and a clamping mechanism 91 and a rotating mechanism 95 connected to the fourth bracket. The fourth bracket includes a second upper cover plate 92, a panel 93, and a fifth fixing plate 97. The panel 93 is horizontally arranged. Two second support plates 94 and the fifth fixing plate 97 are distributed on both sides below the panel 93. The fifth fixing plate 97 is fixedly connected to the first slider 33. The second upper cover plate 92 is fixed on the equipment panel 93. The clamping mechanism 91 is connected to the second upper cover plate 92 through a pin 914. The rotating mechanism 95 is connected to the second upper cover plate 92. The sensor 96 is fixed on the second upper cover plate 92. The sensor 96 is used to detect whether the clamping mechanism 91 returns to the origin after rotating one week under the drive of the rotating mechanism 95.

[0058] As Figure 11 As shown in Figure 11 , the clamping mechanism 91 includes a rotating sleeve 952, a top plate 916, a seventh slider 913, a fourth jaw 911, and a second cylinder lever mechanism 9110. The rotating sleeve 952 is rotatably connected to the fifth bracket, and the axis of the rotating sleeve 952 is vertically arranged. The top plate 916 is located inside the rotating sleeve 952, and the top plate 916 is vertically slidably connected to the rotating sleeve 952. Inclined guide grooves 915 are formed on two opposite sides of the top plate 916, and the inclined directions of the guide grooves 915 on the two sides are opposite. Two seventh sliders 913 are provided. The pin 914 connected to each seventh slider 913 is slidably connected to one guide groove 915. The top of each seventh slider 913 is fixedly connected to a first jaw through an adapter block 912. The seventh slider 913 is horizontally slidably connected to the rotating sleeve 952. Thus, the vertical movement of the top plate 916 will drive the two seventh sliders 913 to move horizontally, realizing the mutual approach or separation between the two seventh sliders 913, and further driving the two first jaws to approach or separate from each other. The top of the rotating sleeve 952 is fixedly connected to a third upper cover plate 951. The first jaw extends out of the third upper cover plate 951 so that the housing assembly can be placed on the surface of the third upper cover plate 951. The bottom end of the top plate 916 is connected to the second cylinder lever mechanism 9110, and the second cylinder lever mechanism 9110 drives the top plate 916 to move up and down.

[0059] As Figure 12a , Figure 12b and Figure 13As shown in the figure, the rotating mechanism 95 includes a pinion gear 953, a large gear 954, and an eighth servo motor 955. The pinion gear 953 is fixed on the output shaft of the eighth servo motor 955, the large gear 954 is fixed on the outside of the rotating sleeve 952, and the pinion gear 953 meshes with the large gear 954. A first positioning protrusion 958 is provided on the rotating sleeve 952, and a second positioning groove 959 is provided on the large gear 954. After the first positioning protrusion 958 is aligned with the second positioning groove 959, the large gear 954 and the rotating sleeve 952 are locked by a positioning pin 956, so that the large gear 954 drives the sleeve 952 to rotate when it rotates. The bottom end of the top plate 916 is vertically rotatably connected to a fixed shaft 918 through a bearing 917. The bottom end of the fixed shaft 918 is connected to the second cylinder lever mechanism 9110 through a universal ball 919. The second cylinder lever mechanism 9110 is used to drive the fixed shaft 918 to move vertically up and down, and then the fixed shaft 918 drives the top plate 916 to move up and down. When the eighth servo motor 955 is started, the eighth servo motor 955 drives the pinion gear 953 to rotate, the pinion gear 953 drives the large gear 954 to rotate, the large gear 954 drives the rotating sleeve 952 to rotate, and the rotating sleeve 952 drives the internal top plate 916, the seventh slider 913, and the fourth jaw 911 to rotate together. At this time, the bottom of the top plate 916 rotates relative to the fixed shaft 918 through the bearing 917, so that the clamping and loosening of the fourth jaw 911 and the rotation of the fourth jaw 911 are relatively independent.

[0060] The rotating sleeve 952 is provided with a third positioning groove 957. The top plate 916 is located in the third positioning groove 957, and the third positioning groove 957 can slide vertically along the axis of the rotating sleeve 952 in the positioning groove 957.

[0061] When the first servo motor 31 is started, the first servo motor 31 drives the first slider 33 and the second base 9 to move together. Then, the second base 9 drives the housing 11 clamped on the second base 9 to move, so that the housing 11 is moved to the position to be processed.

[0062] As Figure 1 and Figure 5a shown in the figure, the four-axis robot 4 includes a second servo motor 41, a connecting ring 42, a robot 43, a three-jaw chuck 44, and a third bracket 45. The third bracket 45 is fixed on the workbench 10. The bottom of the robot 43 is fixed on the third bracket 45 through a pin 914. The three-jaw chuck 44 is connected to the fourth axis of the robot 43 through the connecting ring 42. The three-jaw chuck 44 is provided with a second servo motor 41, and the second servo motor 41 is used to drive the third jaw of the three-jaw chuck 44 to clamp or loosen the housing 11.

[0063] As Figure 5b 、 Figure 5c and Figure 5dAs shown, the three-jaw chuck 44 includes a fixed bracket 441, a main body housing 442, a driving lead screw 443, a central member 444, a sliding block 445, an L-shaped rod 446, and a third jaw 447. The fixed bracket 441 is fixedly connected to the connecting ring 42, and the main body housing 442 is fixedly connected to the fixed bracket 441. The top of the main body housing 442 is fixedly connected with an upper cover 4421, and the bottom is fixedly connected with a lower cover 4422. The central member 444 is located inside the main body housing 442. The driving lead screw 443 passes through the central member 444 and is threadedly connected to the central member 444. The central member 444 is vertically slidably connected to the main body housing 442. The driving lead screw 443 is rotatably connected to the upper cover 4421 and the lower cover 4422. The central member 444 is provided with three planes parallel to the axis of the driving lead screw 443, and each plane is provided with a guiding inclined groove 4441. The included angle between the guiding inclined groove 4441 and the axis of the central member 444 is 50 degrees. Along one rotation direction of the driving lead screw 443, the inclination directions of each guiding inclined groove 4441 are the same. Three sliding blocks 445 are provided, and each sliding block 445 is slidably connected to a guiding inclined groove 4441 respectively. The inner wall of the main body housing 442 is provided with a horizontal limiting groove, and the sliding block 445 is clamped in the limiting groove. Thus, when the central member 444 moves vertically, the sliding block 445 is limited by the main body housing 442 and cannot move along the axial direction of the driving lead screw 443, but can only move along the radial direction of the driving lead screw 443. The bottom of each sliding block 445 is fixedly connected with a third jaw 447 through an L-shaped rod 446. Thus, when the sliding block 445 moves along the radial direction of the driving lead screw 443, it drives the third jaw 447 to clamp or loosen. The second servo motor 41 is connected to the fixed bracket 441, and the output shaft of the second servo motor 41 is connected to the top end of the driving lead screw 443 through a coupling for driving the driving lead screw 443 to rotate. The structural setting of the three-jaw chuck 44 enables the third jaw 447 to have a larger moving stroke. Furthermore, the three-jaw chuck 44 can be applicable to more casings 11 of different models and sizes.

[0064] The main body housing 442 is connected with a sensor, and the top of the central member 444 is connected with a shielding block. During the upward movement of the central block, when the shielding block reaches the position of the sensor, the second servo motor 41 is turned off.

[0065] As Figure 1 and Figure 9As shown, the support frame 8 includes a first upper cover plate 81, a third fixed plate 82, a first support plate 83, and a bottom plate 84. The bottom plate 84 is fixedly connected to the workbench 10. The first upper cover plate 81 is directly above the bottom plate 84. The first upper cover plate 81 and the bottom plate 84 are fixed by two first support plates 83. There is a third fixed plate 82 on each of the upper side edges of the two first support plates 83. The two third fixed plates 82 are both vertically arranged. The third fixed plate 82 is directly above the first slide rail 32, and the length direction of the third fixed plate 82 is perpendicular to the length direction of the first slide rail 32. A plasma processing mechanism 5 is connected to the outside of one third fixed plate 82, and a gluing mechanism 6 is connected to the outside of the other third fixed plate 82. The support frame 8 can also be used for equipment wiring.

[0066] As Figure 1 and Figure 6 shown, the plasma processing mechanism 5 includes a second slide rail 51, a third servo motor 52, a second slider 53, a fourth servo motor 54, a third slide rail 55, a third slider 56, a first fixed plate 57, and a plasma spray gun 58. The second slide rail 51 is fixed on a third fixed plate 82. The third servo motor 52 is located at one end of the second slide rail 51. The third servo motor 52 is used to drive the second slider 53 that is horizontally slidably connected to the second slide rail 51 to move back and forth.
