Description

Technical Field

[0001] This invention relates to the field of capacitor packaging, and more particularly to an automatic capacitor packaging machine. Background Technology

[0002] One step in assembling a capacitor is to wrap the internal core with insulating paper and then insert it into a stainless steel casing. The insulating paper is an insulating and protective component of the capacitor, which can completely cover the internal core (the core component made of electrode foil and dielectric, etc.) to prevent the core from directly contacting the external stainless steel casing, thus preventing short circuits and ensuring the electrical safety of the capacitor. The stainless steel casing is the metal outer shell of the capacitor and belongs to the core protection and auxiliary protection structure, providing robust mechanical protection for the internal core, insulating paper, electrolyte, and other components.

[0003] During the manufacturing process, the wrapped core needs to be inserted into a stainless steel casing. If the core wrapped with insulating paper (i.e., the semi-finished core) is directly inserted into the stainless steel casing, the insulating paper is easily torn. Therefore, a packing machine needs to be designed to insert the capacitor core wrapped with insulating paper into the stainless steel casing with minimal damage to the insulating paper. Summary of the Invention

[0004] To overcome the above-mentioned shortcomings, the purpose of this invention is to provide an automatic capacitor packing machine that does not easily damage the outer insulating paper of the core when inserting the semi-finished core into the metal casing of the capacitor.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is: an automatic capacitor packing machine, comprising:

[0006] A housing conveyor for conveying horizontally oriented metal housings;

[0007] The core feeding device includes a core conveyor table and a core pushing assembly. The core pushing assembly is disposed on the core conveyor table and is used to push the core semi-finished product along the core conveyor table toward the opening end of the metal shell and push it into the metal shell.

[0008] A guide locking device, wherein the outer casing conveyor is disposed on a first side of the guide locking device, and the core feeding device is disposed on a second side of the guide locking device, the guide locking device comprising:

[0009] Guide frame, wherein the guide frame is vertically arranged;

[0010] Four guiding plates are arranged inside the guiding frame. Every two adjacent guiding plates are vertically distributed. The end of one guiding plate is slidably arranged on the side of another guiding plate and abuts against it. The four guiding plates form a "mouth"-shaped guiding opening. A step for engaging with the open end of the metal shell is provided on the first side of each guiding plate, and an outwardly expanding slope is provided on the first side of each guiding plate.

[0011] Four driving sources. The four driving sources are respectively installed on the four side frames of the guiding frame corresponding to them, and connecting blocks are respectively fixed. The four connecting blocks are respectively slidably connected to the four guiding plates through the cooperation of the first sliders and the first sliding rails, and the sliding direction is the extending direction of the guiding plates.

[0012] The beneficial effects of the automatic capacitor packing machine of the present invention are as follows: The shell conveying table conveys the metal shell into the step of the guiding opening. The core feeding device conveys the core semi-finished product to the slope of the guiding opening, and then moves the core semi-finished product along the slope towards the open end of the metal shell and finally inserts it into the metal shell, reducing the possibility of the external insulating paper of the core being scratched and ensuring the capacitor quality; In this application, slopes and steps are formed on the four movable guiding plates, with stronger flexibility, which can be used to match metal shells of different sizes; In addition, it can also be adjusted adaptively to better fit the metal shell and the core semi-finished product.

[0013] Preferably, the depth of the step ≥ the wall thickness of the metal shell; or

[0148] Pressure sensor 229 is located between the second pusher plate 228 and the first pusher plate 227, and is fixedly installed on the first pusher plate 227.

[0149] The automatic capacitor packing machine of this embodiment also includes a casing feeding device 500 and a casing conveyor line 600. The casing conveyor line 600 is used to transport metal casings 610. The metal casings 610 are in a standing position with their open ends facing upwards. The casing feeding device 500 includes a three-axis moving module 510 and a robot arm 520. The robot arm 520 is driven by the three-axis moving module 510 to pick up the metal casings 610 from the casing conveyor line 600 and transfer them to the casing conveyor table 100 which is perpendicular to the horizontal plane.

[0150] like Figure 15 , Figure 16 As shown, the robotic arm 520 includes:

[0151] Rotating gear 521 is rotatably mounted at the free end of the three-axis moving module 510, and a connecting plate 522 is fixedly installed at the bottom of rotating gear 521.

[0152] The feeding gear 523 is fixedly mounted on the downward-facing output shaft of the feeding motor 524. The feeding motor 524 is fixedly mounted on the free end of the three-axis moving module 510 and meshes with the outer gear ring of the rotating gear disk 521.

[0153] A two-way cylinder 525 is fixedly mounted on a connecting plate 522. The telescopic shafts of the two-way cylinder 525 in two directions are respectively connected to clamping plates 526. The two clamping plates 526 are used to clamp the two sides of the metal shell 610.

[0154] An auxiliary cylinder 527 has its cylinder body mounted on one of the clamping plates 526, and the end of the telescopic shaft of the auxiliary cylinder 527 is connected to another clamping plate 526.

[0155] The working principle of this embodiment is as follows:

[0156] The outer shell conveyor line 600 conveys the standing metal outer shell 610. The three-axis moving module 510 drives the robot arm 520 to move to the material picking station of the outer shell conveyor line 600, pick up the metal outer shell 610, and then transfer it to the outer shell conveyor table 100. The outer shell conveyor table 100 is in a vertical state, perpendicular to the horizontal plane. The end face limiting member 160 and the first side limiting member 170 are both in the open state. That is, the telescopic shaft 161a of the limiting cylinder 161 drives the rotating shaft 165 to move outward. The limiting rod 162 fixed at the end of the rotating shaft 165 also moves outward. The limiting protrusion 166 moves from the horizontal section 164a to the arc section 164b. The limiting rod 162 rotates and is in a vertical state. At the same time, the two first side limiting plates 175 are in a far apart state. At this time, the metal outer shell 610 can be placed on the support plate 150 more easily. After the outer casing 610 is in place, the telescopic shaft 161a of the limiting cylinder 161 retracts, the limiting protrusion 166 moves from the arc-shaped section 164b to the horizontal section 164a and resets, and the limiting rod 162 rotates to the horizontal direction, abutting against the end face of the metal casing 610 to limit it and prevent it from tipping over. At this time, the metal casing 610 is limited to prevent it from tipping over. Next, the casing conveying table 100 needs to be rotated to a horizontal state. The telescopic shaft of the casing conveying cylinder 410 retracts, driving the casing conveying table 100 to rotate to a horizontal state, corresponding to the guide port 331 in the horizontal direction. The end face limiting member 160 and the first side limiting member 170 loosen or slightly loosen the metal shell 610, and the core pushing assembly 220 pushes it to the guide port 331 until the open end of the metal shell 610 is engaged with the step 332. First, the driving cylinder drives the lower guide plate 330 to rise until the metal shell 610 is inserted into the step. Then, the three electric cylinders drive the upper guide plate 330, the left guide plate 330, and the right guide plate 330 to move toward the metal shell 610 and clamp the open end of the metal shell 610.

[0157] The core is picked up by other robotic arms and placed on the loading end of the core conveyor 210. At this time, the loading end rotates to face the core semi-finished product loading station, and the core conveyor 210 is in an inclined position with the loading end higher than the limiting end. After the core is wrapped with insulating paper by hand, it will slide along the inclined core conveyor 210 to the core pusher assembly 220 due to gravity and be abutted by the second pusher plate 228. The two sides are limited by the second side limiting member 270. Then the telescopic shaft of the core cylinder 240 extends, and the core conveyor 210 rotates to a horizontal position, but the loading end is still in the core semi-finished product loading station. Driven by motor 261, the core gear 260 rotates, causing the rotating bracket 230 to rotate 180°. The feeding end can rotate to a position where it aligns with the guide port 331. Driven by motor 221, the core screw 222 rotates, causing the sliding block 223 to move along the third slide rail 224 towards the guide port 331. The core semi-finished product moves along the slope 333 towards the guide port 331 and is pushed into the interior from the opening of the metal casing 610 until it is in place. Due to space limitations, a pusher cylinder 226 is used to compensate for the stroke. If the core semi-finished product cannot be pushed into the opening of the metal casing 610, the second pusher plate 228 will move along the guide post towards the first pusher plate 227, and then press the pressure sensor 229 between the first pusher plate 227 and the second pusher plate 228. The pressure sensor 229 will detect a pressure value exceeding the predetermined range. At this time, it indicates that the insulating paper wrapped around the core semi-finished product is not attached to the outer surface of the core within a reasonable error range, or that the opening of the metal casing 610 is too small. The pressure sensor 229 transmits this information to the controller, which then transmits it to the alarm to sound an alarm. The operator then checks the device. If there is no problem and the pressure value detected by the pressure sensor 229 is within a reasonable predetermined range, the core semi-finished product can be directly pushed into the metal casing 610 to complete the casing installation.

[0158] The telescopic shaft of the outer shell conveying cylinder 410 extends again, driving the outer shell conveying table 100 to rotate to a vertical position. During the flipping process, the end face limiting member 160 and the first side limiting member 170 clamp the metal outer shell 610, waiting for the three-axis moving module 510 to drive the robot arm 520 to grab the finished product and transfer it to the receiving platform. When the robot arm 520 grabs the finished product, the end face limiting member 160 and the first side limiting member 170 are released. After the robot arm 520 transfers the finished product to the receiving platform, it goes to the outer shell conveying line 600 to grab the next metal outer shell 610 to the vertical surface formed by the outer shell frame 110 and the support plate 150.
