Description

Technical Field

[0001] The invention relates to a jig for taking out copper nuts and embedding them in a mold, belonging to the field of mold auxiliary jigs. Background Art

[0002] The copper nut picking and in-mold inserting jig is a special tool used to accurately embed copper nuts into plastic or metal parts. Its core functions include: automated picking and positioning, automatic grasping, precise positioning and direction correction of copper nuts through mechanical structures or pneumatic devices, and compatibility between in-mold inserting and post-processing: it supports direct embedding (in-mold inserting) during the injection molding process, or secondary processing such as hot melt and ultrasonic treatment of already molded plastic parts.

[0003] During pre-embedding, the copper nut needs to be moved to the specified position of the mold. In order to prevent deviation, a guide rod needs to be installed in the mold for the copper nut sleeve to limit the position. When moving to the installation position, the sleeve will deviate. Therefore, it is necessary to move and press it with the chuck after installation. The chuck will be deformed for a long time. The deformed chuck will cause the center of the sleeve to deviate, causing subsequent equipment damage. Summary of the Invention

Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the invention for which protection is sought, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0037] In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Therefore, a feature specified as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0038] The existing screw sleeve will be offset when it is moved to the installation position. Therefore, it is necessary to move and press it with the chuck after installation. Over time, the chuck will be deformed. The deformed chuck will cause the center of the screw sleeve to shift, causing subsequent equipment damage. In order to solve the above problem, this case proposes the following technical solutions:

[0039] See also Figures 1 to 7The present invention provides a technical solution for a jig for taking out copper nuts and inlaying them in a mold: its structure includes: an inlay module 1, a picking module 2 is provided on the top of the inlay module 1, the inlay module 1 and the picking module 2 form a frame connection regulator 3, the inlay module 1 includes a limit claw 11 that moves left and right, a supporting positioning plate 12 is provided in the middle of the limit claw 11, the positioning plate 12 is connected to the limit claw 11 through a pusher 13 on the surface, the top of the positioning plate 12 is connected to the picking module 2, an expander 22 is provided on the surface of the bottom plate 21 of the picking module 2, the expander 22 is nested with a movable limit plate 23, the limit plate 23 is connected to the push rod 24 provided at the bottom of the bottom plate 21, the limit claw 11 includes a synchronization plate 103, and the surface of the synchronization plate 103 is provided with a The first clamping claw 101, the second clamping claw 102 is nested at the bottom of the first clamping claw 101, the second clamping claw 102 includes an auxiliary clamping head 211, the second slide rod 202 is nested in the movable hole of the claw body 201 of the auxiliary clamping head 211, and the middle of the second slide rod 202 is provided with a first push arm 204, the synchronization rod 212 of the second clamping claw 102 drives the first push arm 204 to rotate, driving the second clamping claw 102 to be movably connected with the slide claw 113 of the first clamping claw 101.

[0040] When in use: the regulator 3 of the device is used to control the rotation and elevation of the limiting claw 11, the inlay module 1 is used to remove the copper nut, and the top is used to remove the workpiece after injection molding.

[0041] The specific material-taking module 2 includes a base plate 21, and more than two expanders 22 are installed on the surface of the base plate 21. A push rod 24 is provided at the bottom of the base plate 21, and the push rod 24 is connected to the limit plate 23. The surface of the limit plate 23 is provided with a hole matching the expander 22. The expander 22 is used to be inserted into the pipe. The structure of the expander 22 includes a gas rod 223 connected to the air pipe. A support 222 is provided on the surface of the gas rod 223 for installation. An expansion head 221 is provided on the top of the gas rod 223. The expansion head 221 can expand when the gas rod 223 injects air flow, and then when the expansion head 221 is inserted into the mouth of the injection-molded pipe, the expansion can play a role of limiting clamping.

[0042] The structure of the inlay module 1 includes a limiting claw 11, a positioning plate 12 is installed in the middle of the limiting claw 11, and first slide bars 14 are installed on both sides of the positioning plate 12, which are connected to the limiting claw 11 through the first slide bars 14. A pusher 13 for driving the limiting claw 11 is also installed on the surface of the positioning plate 12. When the pusher 13 pushes the limiting claw 11 to move, it will slide on the surface of the first slide bar 14. At the same time, the first slide bar 14 can play a limiting role. A detection arm 15 is set at the bottom of the first slide bar 14. The detection arm 15 is used to detect the distance from the bottom to avoid deformation of the limiting claw 11 caused by excessive pressure. A positioning rod 16 for positioning is also set at the bottom of the positioning plate 12. The positioning rod 16 cooperates with the slot in the mold to improve positioning accuracy.

[0043] The limiting claw 11 is connected to the pusher 13 through the synchronization plate 103 at the back end. Multiple first clamping claws 101 are installed on the synchronization plate 103. The first clamping claw 101 controls the second clamping claw 102 at the bottom for clamping. The second clamping claw 102 is used for embedding the copper nut. The synchronization rod 212 is driven by the reduction motor 213 to move the auxiliary clamp 211 to protect the sliding claw 113 at the bottom of the cylinder 111.

[0044] The specific cylinder 111 is provided with a pneumatic component. When air flow is injected, the internal piston moves, driving the connecting rod to make the sliding claw 113 slide along the sliding seat 112 for clamping. A first limiting groove 114 and a second limiting groove 115 are opened on the surface of the sliding claw 113. The first limiting groove 114 is used to reduce the overall thickness, and the integrity is stronger after the auxiliary clamp 211 is installed. The second limiting groove 115 is used for the nesting of the auxiliary clamp 211. The claw body 201 of the auxiliary clamp 211 is stuck in the second limiting groove 115, and is movably connected, which can be buffered when adjusting the threaded sleeve.

[0045] The structure of the auxiliary chuck 211 includes a claw body 201, which is installed on both sides of the second slide rod 202 of the first push arm 204. The claw body 201 slides with the surface of the second slide rod 202. A buffer sleeve 203 is nested between the first push arm 204 and the second slide rod 202. The limit plate 23 is made of rubber material and can play a buffering role. The second push arm 205 is also nested on the surface of the first push arm 204. The second push arm 205 is installed between the rotating shaft seats 206, and the third push arm 207 is also installed between the rotating shaft seats 206. The third push arm 207 is nested with the rod body on the surface of the first push arm 204.

[0046] When using:

[0047] The drive motor of the regulator 3 can make the material taking module 2 and the inlay module 1 rotate and reverse, the copper nut is placed on the frame, and the regulator 3 controls the inlay module 1 to flip, and after flipping, the limiting claw 11 clamps the copper nut.

[0048] When the cylinder 111 pushes the sliding claw 113 to move and clamp, the surface of the claw body 201 slides synchronously.

[0049] When arriving at the injection molding area for pre-embedded copper nut, the limiting claw 11 is flipped to the specified position, and air flow is injected into the pusher 13 to drive the push rod of the pusher 13 to press, so that the limiting claw 11 moves horizontally along the first slide rod 14, and the copper nut is stuck at the outer end of the mold.

[0050] Then the reduction motor 213 is started, and a gear set is provided inside the reduction motor 213, which can drive the synchronization rod 212 to rotate. The synchronization rod 212 is engaged with the third push arm 207 and the second push arm 205. The third push arm 207 drives the rod body on the surface of the first push arm 204, which can increase the pushing torque.

[0051] The first push arm 204 drives the front claw body 201 to rotate through the second slide rod 202, thereby allowing the copper nut to move flexibly inside the mold. Compared with directly placing it with the slide claw 113, frequent impacts are required for installation.

[0052] After being pushed by the claw body 201, it is quickly aligned, and then the claw body 201 is expanded under the action of the sliding claw 113. After expansion, the first push arm 204 drives the claw body 201 to retract, and then the sliding claw 113 re-clamps, and the reduction motor 213 reciprocates the synchronous rod 212 to move the auxiliary clamp 211 so that the copper nut can be pushed into the limit rod of the mold.

[0053] After the injection molding is completed, the regulator 3 rotates the material removal module 2 to align with the mold position, and the expander 22 is engaged with the pipe fitting. After engagement, air flow is injected to expand the expansion head 221, and then the whole unit is moved to remove the mold.

[0054] The improved device forms a composite claw by engaging the sliding claw 113 with the claw body 201, which has sufficient contact area to prevent its deviation during clamping, and can control the gap between the claw body 201 and the sliding claw 113 when some copper nuts are longer, making the attachment more stable.

[0055] The third push arm 207 cooperates with the second push arm 205 to jointly push the first push arm 204, which is stronger when pressing. The first push arm 204 is connected to the second slide bar 202 through a universal buffer sleeve 203, which can buffer the impact when pressing. Since the claw body 201 and the sliding claw 113 are separated independently, the pressing pressure can be avoided from damaging the internal components of the cylinder 111, making the operation of the entire component more stable.

[0056] The above only describes the basic principles and preferred embodiments of the present invention. Those skilled in the art may make many changes and improvements based on the above description, and these changes and improvements should fall within the scope of protection of the present invention.

[0057] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
