Description

Technical Field

[0001] This utility model relates to the field of hot soldering production technology, and in particular to a fully automatic ball soldering machine. Background Technology

[0002] In existing technologies, the common method for manufacturing small, hollow plastic spherical products is to use an injection molding machine to create several hemispheres, then remove each hemisphere individually, allow it to cool, and then manually melt the end faces of the hemispheres. The hemispheres are then placed in pairs into a mold to form a spherical structure. The drawback of this production method is the long intervals between each step of the process. The time spent removing the hemispheres from the injection molding machine, allowing them to cool, and then manually melting the end faces is time-consuming, resulting in low production efficiency. Against this backdrop, the applicant is dedicated to developing a fully automatic ball-welding machine that integrates the entire process of demolding, end-face melting, and ball assembly of plastic hemispheres, significantly reducing the waiting time between steps and improving production efficiency. Utility Model Content

[0003] The purpose of this invention is to achieve integrated operation of plastic hemispheres from demolding, melting the end face, and assembling, thereby significantly reducing the waiting time between each process and improving production efficiency.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A fully automatic ball welding machine includes a robotic arm, a ball mold mechanism, and a hot welding mechanism. The ball mold mechanism includes a first drive mechanism, a first slide rail, a left half mold, and a right half mold. The left half mold and the right half mold are symmetrically slidably mounted on the first slide rail. A left ball groove is provided on the left half mold, and a right ball groove is provided on the right half mold. The left ball groove and the right ball groove are symmetrically arranged. The first drive mechanism simultaneously drives the left half mold and the right half mold to separate or close along the first slide rail. The robotic arm cooperates with the ball mold mechanism. The hot welding mechanism includes a second driving mechanism, a second slide rail, and a welding plate. The second driving mechanism drives the welding plate to slide on the second slide rail, thereby driving the welding plate to move back and forth between the center of the left half mold and the right half mold.

[0005] Furthermore, the robotic arm includes an X-axis drive mechanism, a Y-axis drive mechanism, a Z-axis drive mechanism, and a robotic gripper. The X-axis drive mechanism drives the Y-axis drive mechanism to move back and forth along the X-axis direction, the Y-axis drive mechanism drives the Z-axis drive mechanism to move back and forth along the Y-axis direction, and the Z-axis drive mechanism drives the robotic gripper to move back and forth along the Z-axis direction.

[0006] Furthermore, the mechanical gripper includes a rotary drive mechanism, a left suction plate, and a right suction plate. The rotary drive mechanism drives the right suction plate to rotate, and the left suction plate and the right suction plate cooperate with each other.

[0007] Furthermore, a plurality of left hemispherical seats are fixedly provided on the left suction plate, a first air passage is opened inside the left suction plate, a first suction cup is provided on the left hemispherical seat, and the first air passage is connected to the first suction cup. Several right hemisphere seats are fixedly installed on the right suction plate. A second air passage is opened inside the right suction plate. A second suction cup is installed on the right hemisphere seat. The second air passage is connected to the second suction cup.

[0008] Furthermore, the ball mold mechanism also includes a support frame and a guide rod, the guide rod being fixedly mounted on the support frame and passing through both the left half mold and the right half mold.

[0009] Furthermore, the hot welding mechanism also includes an adjustment plate, which is driven by the second driving mechanism to slide on the second slide rail, thereby driving the adjustment plate to move back and forth between the center of the left half mold and the right half mold.

[0010] Furthermore, there are two sets of the second slide rails, which are arranged in parallel to each other, and the upper and lower ends of the adjustment plate and the welding plate are respectively slidably mounted on the two sets of the second slide rails.

[0011] Furthermore, a third air passage is provided inside the left half mold, and the third air passage is connected to the interior of the left ball groove.

[0012] Furthermore, a fourth air passage is provided inside the left half mold, and the fourth air passage is connected to the inside of the right ball groove.

[0013] Furthermore, it also includes a feeding box, which is located below the hot welding mechanism.

[0014] The beneficial effects of this utility model are as follows: When manufacturing plastic ball products, this utility model uses a robotic arm to directly pick up the injection-molded hemispheres from the injection molding machine and moves the hemispheres in batches to the left ball groove of the left half mold and the right ball groove of the right half mold. The second drive mechanism drives the welding plate to extend to the center of the left and right half molds, and the first drive mechanism simultaneously drives the left and right half molds to close. Thus, the welding plate melts the end faces of the hemispheres in the left and right ball grooves. Then, the first drive mechanism simultaneously drives the left and right half molds to separate, and the second drive mechanism drives the welding plate away from the center of the left and right half molds. The first drive mechanism then drives the left and right half molds to close again, so that the end faces of the two symmetrical hemispheres fit together to form a finished sphere. Compared with traditional technology, this utility model realizes the integrated operation of hemisphere ejection, end face melting, and sphere assembly, eliminating the need to wait for the hemispheres to cool before manually melting the end faces, thereby significantly shortening the production time and improving production efficiency.

Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] like Figures 1 to 6 The fully automatic ball welding machine shown includes a robot arm 1, a ball mold mechanism 2, a hot welding mechanism 3, and a feeding box 4; the robot arm 1 and the ball mold mechanism 2 cooperate with each other, and the feeding box 4 is located below the hot welding mechanism 3.

[0018] The robotic arm 1 includes an X-axis drive mechanism 11, a Y-axis drive mechanism 12, a Z-axis drive mechanism 13, and a robotic gripper 14. The X-axis drive mechanism 11 drives the Y-axis drive mechanism 12 to move back and forth along the X-axis direction, the Y-axis drive mechanism 12 drives the Z-axis drive mechanism 13 to move back and forth along the Y-axis direction, and the Z-axis drive mechanism 13 drives the robotic gripper 14 to move back and forth along the Z-axis direction. The three-axis linkage of the X-axis drive mechanism 11, the Y-axis drive mechanism 12, and the Z-axis drive mechanism 13 drives the robotic gripper 14 to move.

[0019] The mechanical gripper 14 includes a rotary drive mechanism 141, a left suction plate 142, and a right suction plate 143. The rotary drive mechanism 141 drives the right suction plate 143 to rotate, and the left suction plate 142 cooperates with the right suction plate 143. The rotary drive mechanism 141 drives the right suction plate 143 to rotate 180 degrees to the left, so that the right suction plate 143 and the left suction plate 142 are on the same plane, which is conducive to the right suction plate 143 and the left suction plate 142 simultaneously picking up hemispheres from the internal mold of the injection molding machine 5. The rotary drive mechanism 141 drives the right suction plate 143 to rotate 180 degrees to the right, so that the right suction plate 143 rotates to the back of the left suction plate 142. At this time, it is convenient to transfer the hemisphere on the right suction plate 143 to the right ball groove of the right half mold 24, and at the same time transfer the hemisphere on the left suction plate 142 to the left ball groove of the left half mold 23, so that the left half mold 23 and the right half mold 24 can transfer hemispheres simultaneously.

[0020] A number of left hemispherical seats 1421 are fixedly installed on the left suction plate 142. A first air passage is opened inside the left suction plate 142. A first suction cup is installed on the left hemispherical seat 1421. The first air passage is connected to the first suction cup. A number of right hemispherical seats 1431 are fixedly installed on the right suction plate 143. A second air passage is opened inside the right suction plate 143. A second suction cup is installed on the right hemispherical seat 1431. The second air passage is connected to the second suction cup.

[0021] Both the first and second air passages are connected to a solenoid valve, which is connected to a suction device. During operation, by controlling the solenoid valve, the positive and negative air pressure inside the first and second air passages can be changed, thereby enabling the first and second suction cups to suck up and blow away the hemisphere.

[0022] The ball mold mechanism 2 includes a first drive mechanism 21, a first slide rail 22, a left half mold 23, a right half mold 24, a support frame 25, and a guide rod 26. The left half mold 23 and the right half mold 24 are symmetrically slidably mounted on the first slide rail 22. A left ball groove is provided on the left half mold 23, and a right ball groove is provided on the right half mold 24. The left ball groove and the right ball groove are symmetrically arranged. The first drive mechanism 21 simultaneously drives the left half mold 23 and the right half mold 24 to separate or close along the first slide rail 22.

[0023] The guide rod 26 is fixedly mounted on the support frame 25, and the guide rod 26 passes through both the left half mold 23 and the right half mold 24. The guide rod 26 guides the left half mold 23 and the right half mold 24, thereby improving the mold closing accuracy.

[0024] The left half mold 23 has a third air passage inside, which is connected to the interior of the left ball groove; the left half mold 23 also has a fourth air passage inside, which is connected to the interior of the right ball groove. Both the third and fourth air passages are connected to a solenoid valve, which is connected to an air extraction device. During operation, by controlling the solenoid valve, the positive and negative air pressure inside the third and fourth air passages can be changed, thereby enabling the left and right ball grooves to have the function of sucking up and blowing away the half-ball.

[0025] The robotic arm 1 picks up the hemisphere that has been injection molded in the injection molding machine 5 and moves the hemisphere into the left ball groove and the right ball groove. It operates the solenoid valve to make the air pressure inside the third air passage and the fourth air passage negative. At this time, the left ball groove and the right ball groove hold the hemisphere.

[0026] The hot welding mechanism 3 includes a second drive mechanism 31, a second slide rail 32, a welding plate 33, and an adjustment plate 34. The second drive mechanism 31 drives the welding plate 33 to slide on the second slide rail 32, thereby driving the welding plate 33 to move back and forth between the left half mold 23 and the right half mold 24.

[0027] The second drive mechanism 31 drives the adjustment plate 34 to slide on the second slide rail 32, thereby driving the adjustment plate 34 to move back and forth between the left half mold 23 and the right half mold 24.

[0028] There are two sets of second slide rails 32, which are arranged in parallel to each other. The upper and lower ends of the adjustment plate 34 and the welding plate 33 are respectively slidably mounted on the two sets of second slide rails 32.

[0029] After the hemispheres are attracted to the left ball groove on the left half mold 23 and the right ball groove on the right half mold 24, the second drive mechanism 31 drives the adjustment plate 34 to extend to the center of the left half mold 23 and the right half mold 24. The first drive mechanism 21 drives the left half mold 23 and the right half mold 24 to close, thereby leveling the hemispheres in the left ball groove and the right ball groove, so that the ends of the hemispheres are on the same plane, which is beneficial to the subsequent hot melting operation of the welding plate 33.

[0030] The spherical products produced by this invention have fewer weld marks, require less grinding time, and generate less waste. This invention enables fully automated production, resulting in faster production speeds and lower deformation rates.

[0031] The working principle of this utility model is as follows: the three-axis linkage of the X-axis drive mechanism 11, the Y-axis drive mechanism 12, and the Z-axis drive mechanism 13 drives the mechanical claw 14 to move between the two internal molds of the injection molding machine 5. The rotation drive mechanism 141 drives the right suction plate 143 to rotate 180 degrees to the left, so that the right suction plate 143 and the left suction plate 142 are on the same plane. The hemisphere is picked up from the internal mold of the injection molding machine 5 by the first suction cup on the left suction plate 142 and the second suction cup on the right suction plate 143 at the same time.

[0032] The three-axis linkage of the X-axis drive mechanism 11, Y-axis drive mechanism 12, and Z-axis drive mechanism 13 drives the mechanical claw 14 to move between the left half mold 23 and the right half mold 24. The rotation drive mechanism 141 drives the right suction plate 143 to rotate 180 degrees to the right, so that the right suction plate 143 rotates to the back of the left suction plate 142. At this time, the hemisphere on the right suction plate 143 is transferred to the right ball groove of the right half mold 24, and the hemisphere on the left suction plate 142 is transferred to the left ball groove of the left half mold 23, so that the left half mold 23 and the right half mold 24 transfer the hemisphere at the same time.

[0033] The second drive mechanism 31 drives the adjustment plate 34 to extend to the center of the left half mold 23 and the right half mold 24. The first drive mechanism 21 drives the left half mold 23 and the right half mold 24 to close, thereby leveling the hemispheres in the left and right ball grooves so that the ends of the hemispheres are on the same plane, which is beneficial for the subsequent hot melting operation of the welding plate 33.

[0034] The first driving mechanism 21 drives the left half mold 23 and the right half mold 24 to separate. The second driving mechanism 31 drives the welding plate 33 to extend to the center of the left half mold 23 and the right half mold 24. The first driving mechanism 21 simultaneously drives the left half mold 23 and the right half mold 24 to close, thereby melting the hemispherical end faces in the left and right ball grooves through the welding plate 33. Then, the first driving mechanism 21 simultaneously drives the left half mold 23 and the right half mold 24 to separate. The second driving mechanism 31 drives the welding plate 33 to leave the center of the left half mold 23 and the right half mold 24. The first driving mechanism 21 drives the left half mold 23 and the right half mold 24 to close again, thereby making the end faces of the two symmetrical hemispheres fit together to form a finished sphere.

[0035] The first drive mechanism 21 drives the left half mold 23 and the right half mold 24 to separate again. By controlling the solenoid valve, the internal air pressure of the third air passage and the fourth air passage is positive, thereby blowing the finished ball in the left ball groove or the right ball groove into the feeding box 4.

[0036] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of protection of the present utility model. Therefore, any equivalent changes made in accordance with the scope of the patent application of the present utility model shall still fall within the scope of the present utility model.
