Description

Technical Field

[0001] The invention belongs to the technical field of insulating busbar manufacturing, and in particular relates to a metal shell cast insulating busbar and a manufacturing method thereof. Background Art

[0002] The enclosed busbar is a busbar system composed of a metal plate (steel plate or aluminum plate) as a protective shell, a conductive bar, an insulating material and related accessories. It is mainly used to transmit electrical energy and has the ability to collect and distribute electricity.

[0003] Based on the prior art, it is found that in the process of casting the busbar with the existing busbar casting equipment, since the insulating casting material is viscous as a whole, it is difficult for the insulating casting material to achieve a self-leveling effect after being cast into the template. The insulating casting material needs to be scraped flat manually with a spatula. This method is inefficient and it is difficult to ensure that the level of the insulating casting material is consistent at all locations, thereby affecting the quality of the busbar after casting.

[0004] In addition, bubbles are easily generated in the insulating castable, and the presence of bubbles will reduce the density of the insulating castable, thereby affecting the structural strength of the busbar after casting, and easily causing the busbar to deform or be damaged during subsequent use.

[0015] As a preferred technical solution of the present invention, a method for manufacturing a metal shell cast insulated busbar comprises the following steps:

[0016] S1: Clamping and limiting, arranging the conductive bars to be cast neatly in the template, and then clamping and limiting the template by multiple clamps;

[0017] S2: pouring, delivering the insulating castable into the formwork through the nozzle;

[0018] S3: scraping, the insulating castable is scraped flat by the combination of the scraper and the telescopic plate;

[0019] S4: Remove bubbles, break the bubbles in the insulating castable by reciprocating the needle, and promptly flatten the insulating castable by the scraper and telescopic plate;

[0020] S5: Vibration. High-frequency vibration is generated by a vibrating rod. The vibrating rod causes the template to vibrate, and then the insulating castable in the template generates high-frequency vibration, which helps to make the bubbles in the insulating castable float up, making it easier for the needle to scratch them, thereby improving the density of the material.

[0021] The advantages and positive effects of the present invention are:

[0022] (1) By conveying the insulating castable material into the conduit and allowing the insulating castable material to flow along the circular tube, the insulating castable material is finally conveyed into the template through the nozzle, thereby realizing automatic casting of the conductive bar, improving efficiency and reducing human labor intensity.

[0023] (2) Use a camera to detect the bend of the conductive row, and adjust the positions of all nozzles so that each nozzle can always align with the gap between two adjacent conductive rows, and then continue pouring until the pouring is completed.

[0024] (3) The scraper and all the pins are inserted into the insulating castable and contacted with the insulating castable, and then the scraper is moved along the inner side of the template to scrape the insulating castable flat. The elastic force generated by the corresponding elastic member I causes the telescopic plate to slide out of the flat plate and press against the inner side of the curved part of the template, so that the scraper and the telescopic plate combination jointly scrape the insulating castable flat, so that the horizontal height of the insulating castable at various locations is kept consistent, thereby improving the quality of the conductive bar after casting.

[0025] (4) The bubbles generated in the insulating castable are broken by the reciprocating movement of the pin, and the insulating castable can be scraped flat in time by the scraper and the telescopic plate, so as to avoid bubbles in the insulating castable, thereby improving the structural strength of the conductive bar after casting and reducing the possibility of deformation or damage of the conductive bar during subsequent use.

[0026] (5) The vibrating rod generates high-frequency vibration, which causes the template to vibrate, and then the insulating castable in the template generates high-frequency vibration, which helps to make the bubbles in the insulating castable float up, making it easier for the pins to cut through, thereby improving the density of the material. It can also cooperate with all the pins to break the bubbles in the insulating castable, thereby improving the quality and performance of the conductive bar after casting.

[0045] The entire left side surface of the telescopic plate 216 is coated with an anti-sticking coating to reduce the adhesion of the insulating casting material to the telescopic plate 216.

[0046] It further includes a motor II 301, a transmission shaft II 302, a lever 303, a limit frame 304, a limit box 305 and an elastic member II 306; the left side of the flat plate 211 is fixedly connected with the motor II 301; the output shaft of the motor II 301 is fixedly connected with the transmission shaft II 302; the transmission shaft II 302 is rotationally connected with the flat plate 211 and penetrates through the flat plate 211; the lever 303 is fixedly connected to the transmission shaft II 302; the right side of the flat plate 211 is fixedly connected with the limit frame 304; the limit box 305 is slidably connected to the limit frame 304, and the lever 303 is located inside the limit box 305; the limit box 305 is fixedly connected with the scraping plate 215; two elastic members II 306 are fixedly connected between the limit box 305 and the limit frame 304.

[0047] The driving mechanism includes an electric slide rail I 201, an electric slider I 202, an electric slide rail II 203, an electric slider II 204, a fixing frame 205 and an electric actuator I 206; the electric slide rail I 201 is fixedly connected to the support frame 2; the electric slider I 202 is slidably connected to the electric slide rail I 201; the electric slide rail II 203 is fixedly connected to the electric slider I 202; the electric slider II 204 is slidably connected to the electric slide rail II 203; the fixing frame 205 is fixedly connected to the electric slider II 204; two electric actuators I 206 are fixedly connected to the fixing frame 205. The electric actuator I 206 is an electric push rod; the telescopic parts of the two electric actuators I 206 are jointly fixedly connected to the fixing plate 207.

[0048] Manually place the template 3 on the chassis 1 in advance, then neatly arrange the conductive bars 5 to be cast in the template 3, and then use a plurality of clamps 4 to clamp and limit the template 3, thereby realizing the limitation of the arranged conductive bars 5. Then pour the insulating casting material into the template 3. The insulating casting material usually has epoxy resin as the main component and may be mixed with other materials such as volcanic rock inorganic minerals according to actual needs. After being made, the insulating casting material is in a viscous state as a whole;

[0049] When pouring the insulated busbar, first connect the external pump machine for transporting the insulating pouring material to the conduit 212 in advance. Then, taking the front side of the chassis 1 as a reference, control the electric slider I 202 to start moving leftward along the electric slide rail I 201. The movement of the electric slider I 202 drives all the connected components to move. Again, taking the front side of the chassis 1 as a reference, control the electric slider II 204 to start moving forward along the electric slide rail II 203, thereby driving all the connected components to move. Finally, make the flat plate 211 move to align with the template 3 and be located above the busbar 5. Then, control the two electric actuators I 206 to start and drive the fixing plate 207 to move downward. The movement of the fixing plate 207 drives all the connected components to move, so that all the nozzles 214 move downward to approach the busbar 5, and each nozzle 214 aligns with the gap between two adjacent busbars 5. Then, control the external pump machine to start operating and transport the insulating pouring material into the conduit 212, and make the insulating pouring material flow along the round tube 213. Finally, the insulating pouring material is transported into the template 3 through the nozzles 214, thus realizing the automatic pouring of the busbar 5, improving the efficiency and reducing the labor intensity of the human body at the same time.

[0050] And when pouring to the bent part of the busbar 5, that is, when the flat plate 211 moves to the bent part of the busbar 5, detect the bent part of the busbar 5 through the camera 2071 and transmit the detection data to the central processor. Then, control the motor I 208 to start. The rotation of the output shaft of the motor I 208 drives the transmission shaft I 209 to rotate. The rotation of the transmission shaft I 209 drives the support arm 210 to rotate. The rotation of the support arm 210 drives the flat plate 211 to rotate. The rotation of the flat plate 211 drives all the connected components to rotate, thereby adjusting the positions of all the nozzles 214, so that each nozzle 214 can always align with the gap between two adjacent busbars 5. Then, continue the pouring until the pouring is completed.

[0051] However, during the process of pouring the busbar 5, since the insulating pouring material is overall viscous, it is difficult for the insulating pouring material to achieve the self-leveling effect after being poured into the template 3. It is still necessary for workers to use a spatula to scrape the insulating pouring material flat. This method has low efficiency and is difficult to ensure that the horizontal heights of all parts of the insulating pouring material are the same, which will affect the quality of the busbar 5 after pouring. Moreover, air bubbles are likely to be generated in the insulating pouring material, and the existence of air bubbles will reduce the density of the insulating pouring material, thereby affecting the structural strength of the busbar 5 after pouring, and it is easy to cause the busbar 5 to deform or be damaged during subsequent use;

[0052] To solve the above problems, after pouring the insulation casting material into the template 3 through all the nozzles 214, control the two electric actuators I 206 to start and drive the fixing plate 207 to move downward. The movement of the fixing plate 207 drives the movement of all the connected components, so that the scraper 215 and all the pins 2151 are inserted into the insulation casting material and come into contact with it. Also, the two telescopic plates 216 are inserted into the insulation casting material. Since the left side of the telescopic plate 216 is cut into an inclined shape, when the telescopic plate 216 moves to the inside of the template 3, the telescopic plate 216 will be squeezed by the inside of the template 3, causing the telescopic plate 216 to retract into the flat plate 211. And the elastic force generated by the corresponding elastic member I 2161 makes the telescopic plate 216 always press against the inside of the template 3. Then, control the electric slider I 202 and the electric slider II 204 to start in the same way as above, so that the scraper 215 moves along the inside of the template 3, thus leveling the insulation casting material;

[0053] And when the flat plate 211 moves to the bent part of the busbar 5, the camera 2071 detects the bent part of the busbar 5 and transmits the detection data to the central processor. Then, control the motor I 208 to start in the same way as above. The output shaft of the motor I 208 rotates, driving the transmission shaft I 209 to rotate. The rotation of the transmission shaft I 209 drives the rotation of all the connected components, thus driving the rotation of the two telescopic plates 216. At the same time, the elastic force generated by the corresponding elastic member I 2161 of the telescopic plate 216 makes the telescopic plate 216 slide out of the flat plate 211 and press against the inside of the bent part of the template 3, so that the combination of the scraper 215 and the telescopic plate 216 levels the insulation casting material together, keeping the horizontal height of each part of the insulation casting material consistent, thereby improving the quality of the cast busbar 5.

[0054] And while the scraper 215 levels the insulation casting material, control the motor II 301 to start. The output shaft of the motor II 301 rotates, driving the transmission shaft II 302 to rotate. The rotation of the transmission shaft II 302 drives the lever 303 to rotate. The rotation of the lever 303 squeezes the limit frame 305, causing the limit frame 305 to reciprocate along the limit frame 304 and compress all the elastic members II 306. Then, the movement of the limit frame 305 drives the movement of the scraper 215, and the movement of the scraper 215 drives all the pins 2151 to reciprocate. Thus, the bubbles generated in the insulation casting material are punctured by the reciprocating movement of the pins 2151, and the insulation casting material can be leveled in time by the scraper 215 and the telescopic plate 216. Therefore, it is possible to avoid the insulation casting material containing bubbles, thereby improving the structural strength of the cast busbar 5 and reducing the possibility of deformation or damage of the busbar 5 during subsequent use.

[0062] S5: Vibration, generating high-frequency vibration through the vibrating rod 403, the vibrating rod 403 causes the template 3 to vibrate, and further causes the insulating casting material in the template 3 to generate high-frequency vibration, which helps the air bubbles in the insulating casting material to float up, facilitating the insertion needle 2151 to break them, thereby improving the density of the material.

[0063] To further reduce the air bubbles in the insulating casting material, when the flat plate 211 moves to align with the template 3, control the two electric actuators II 401 to start and drive a special-shaped connecting rod 402 to move respectively, so that the two special-shaped connecting rods 402 move away from each other. When the flat plate 211 moves into the template 3, at this time, the two vibrating rods 403 are respectively located outside the two templates 3, and the two vibrating rods 403 respectively abut against the outer surface of the two templates 3. Then control the vibration motor arranged in the vibrating rod 403 to operate, so that the vibrating rod 403 generates high-frequency vibration, the vibrating rod 403 causes the template 3 to vibrate, and further causes the insulating casting material in the template 3 to generate high-frequency vibration, which helps the air bubbles in the insulating casting material to float up, facilitating the insertion needle 2151 to break them, thereby improving the density of the material, and being able to cooperate with all the insertion needles 2151 to break the air bubbles in the insulating casting material, thereby improving the quality and performance of the conductive bar 5 after casting.
