[0018] The present application is further described in detail below in conjunction with the accompanying drawings.

[0019] The embodiment of the present application discloses a molded case circuit breaker base copper parts assembly machine.

[0020] Figure 8 The molded case circuit breaker base after the copper parts are assembled for this application includes a socket slot 7 and copper parts 8 assembled on both sides of the socket slot 7. Please refer to the socket slot 7 and copper parts 8 involved in the subsequent documents. Figure 8 .

[0021] Reference Figure 1 , Figure 2 The molded case circuit breaker base copper parts assembly machine includes a conveyor belt 1, a positioning mechanism 2, an assembly mechanism 3, a first lifting seat 4, a second lifting seat 5 and a discharge mechanism 6. The conveyor belt 1 is driven by a motor and is used to transport the molded case circuit breaker base backward. The positioning mechanism 2 includes an assembly platform 20, which is set above the conveyor belt 1. The assembly platform 20 is provided with a positioning component 21, which is used to limit and fix the molded case circuit breaker base on the assembly station of the assembly platform 20.

[0022] like Figure 2 , Figure 3As shown, the positioning assembly 21 includes a lifting cylinder 210 fixedly mounted above the assembly platform 20, the piston rod of the lifting cylinder 210 is vertically downwardly arranged, and a positioning member 211 facing the assembly platform 20 is fixedly mounted on the piston rod of the lifting cylinder 210. The positioning member 211 is used to be inserted into the plug slot of the molded case circuit breaker base from top to bottom. When the positioning member 211 is inserted into the plug slot of the molded case circuit breaker base under the drive of the lifting cylinder 210, the molded case circuit breaker base will be limited and fixed on the assembly station of the assembly platform 20.

[0023] like Figure 2 , Figure 3 As shown, the first lifting seat 4 and the second lifting seat 5 are arranged in sequence along the feeding direction of the conveyor belt 1, and the first lifting seat 4 and the second lifting seat 5 are symmetrically arranged on the front and rear sides of the assembly platform 20. Cylinders are arranged at the bottom of the first lifting seat 4 and the second lifting seat 5, and the first lifting seat 4 and the second lifting seat 5 are lifted and lowered in the vertical direction under the drive of their respective cylinders.

[0024] like Figure 2 , Figure 3 As shown, since the spacing height formed between the assembly platform 20 and the upper surface of the conveyor belt 1 is smaller than the height of the molded case circuit breaker base, when the molded case circuit breaker base to be assembled moves to the top of the first lifting seat 4 under the conveyance of the conveyor belt 1, the molded case circuit breaker base will be limited on the first lifting seat 4 by the assembly platform 20, and the molded case circuit breaker base will not be able to pass smoothly under the assembly platform 20. Then, the first lifting seat 4 will lift the molded case circuit breaker base to be assembled from the conveyor belt 1 upwards under the push of the cylinder until the bottom surface of the molded case circuit breaker base is flush with the upper surface of the assembly platform 20, and the molded case circuit breaker base is at the feeding station.

[0025] like Figure 2 , Figure 3 As shown, a pusher 10 is also included which is mounted above the conveyor belt 1. The pusher 10 is located on the side of the first lifting seat 4 away from the assembly platform 20. In this embodiment, the pusher 10 is a cylinder, and the piston rod of the pusher 10 faces the assembly platform 20. The pusher 10 is used to push the molded case circuit breaker base at the feeding station into the assembly station of the assembly platform 20 in the horizontal direction.

[0026] like Figure 3 , Figure 4 As shown, the assembly mechanism 3 is symmetrically arranged on the left and right sides of the assembly platform 20, and the assembly mechanism 3 is used to periodically assemble the copper parts into the molded case circuit breaker base located at the assembly station of the assembly platform 20. There are three copper parts to be assembled on the same side of the molded case circuit breaker base, so the assembly mechanism 3 will synchronously complete the assembly work of the three copper parts on the same side each time.

[0027] like Figure 3 , Figure 4 As shown, the assembly mechanism 3 includes an assembly seat 30, on which an assembly cylinder 31 is provided, and a push plate 32 is fixedly installed on the piston rod of the assembly cylinder 31, and the assembly cylinder 31 is used to push the push plate 32 to reciprocate along the direction in which the copper parts are assembled into the plug-in slot of the molded case circuit breaker base. The push plate 32 will synchronously assemble the three copper parts on the same side each time, and the assembly seat 30 is also provided with three assembly grooves 33, and the assembly grooves 33 are opposite to the plug-in slots of the molded case circuit breaker base to be assembled on the assembly station. When the three copper parts on the same side are moved to the openings of their respective corresponding assembly grooves 33, the push plate 32 will be driven by the piston rod of the assembly cylinder 31 to push the three copper parts along their respective assembly grooves 33 into the plug-in slots of the molded case circuit breaker base to be assembled, thereby completing the assembly of the copper parts. During assembly, the assembly mechanisms 3 on both sides will achieve synchronous assembly, which greatly improves the assembly efficiency.

[0028] like Figure 1 , Figure 4 As shown, the assembly mechanism 3 also includes two copper vibrating plates 34, which transport the copper pieces in sequence to the corresponding assembly seats 30 through the material channel. A material transfer cylinder 35 is mounted on the assembly seat 30, and a material transfer seat 36 is fixedly arranged on the piston rod of the material transfer cylinder 35. The material transfer cylinder 35 is used to drive the material transfer seat 36 to slide back and forth along the feeding direction of the copper vibrating plate 34 material channel.

[0029] like Figure 3 , Figure 4 As shown, two adjusting cylinders 360 are fixedly mounted on the material shifting seat 36, a material shifting piece 37 is fixedly arranged on the piston rod of the adjusting cylinder 360, a material shifting column 38 is fixedly arranged at the bottom of the material shifting seat 36, and the material shifting piece 37 is symmetrically arranged on the front and rear sides of the material shifting column 38. The material shifting piece 37 and the material shifting column 38 are used to be inserted into the respective opposite copper piece wiring holes, and the three copper pieces are synchronously moved to the openings of each assembly groove 33 under the push of the piston rod of the material shifting cylinder 35.

[0030] like Figure 3 , Figure 4As shown, the adjusting cylinder 360 is used to adjust the interval between the material moving parts 37 and the material moving column 38 on both sides, and the assembly seat 30 is also provided with a driving cylinder 39, and the material moving cylinder 35 is installed on the piston rod of the driving cylinder 39, and the driving cylinder 39 is used to drive the material moving seat 36 to rise and fall in the vertical direction. When the material moving parts 37 and the material moving column 38 move to the material path of the copper vibrating plate 34, the material moving parts 37 on both sides will move to be close to the material moving column 38 under the drive of the respective adjusting cylinders 360, and then the driving cylinder 39 will drive the material moving seat 36 to descend, and the material moving parts 37 on both sides and the material moving column 38 will be inserted downward into the respective relative copper wiring holes, and then under the drive of the material moving cylinder 35, the three copper pieces will be synchronously moved out of the material path of the copper vibrating plate 34, and finally the copper pieces will be adjusted by the adjusting cylinder 360 and move to the openings of the respective corresponding assembly slots 33. Then the driving cylinder 39 drives the material shifting seat 36 to move upward, and then the material shifting cylinder 35 drives the material shifting seat 36 to retreat and reset to prepare for a new round of material shifting work.

[0031] like Figure 3 , Figure 4 As shown, when the molded case circuit breaker base completes the assembly of the copper parts, the lifting cylinder 210 will drive the positioning member 211 to withdraw from the plug slot of the molded case circuit breaker base, and then the pusher 10 will start again, and move the molded case circuit breaker base to be assembled in front from the first lifting seat 4 to the assembly platform 20. At this time, the assembled molded case circuit breaker base on the assembly platform 20 will be pushed onto the second lifting seat 5 in the raised state, and then the second lifting seat 5 will move the assembled molded case circuit breaker base from the assembly platform 20 back down to the conveyor belt 1.

[0032] like Figure 5 , Figure 6 As shown, the unloading mechanism 6 includes a unloading rack 60 located on one side of the discharge port of the conveyor belt 1, and the unloading rack 60 is vertically arranged. A unloading chain 61 is arranged on the unloading rack 60 through the rotation of a motor, and a plurality of unloading parts 62 arranged in sequence along the rotation direction of the unloading chain 61 are fixedly arranged on the unloading chain 61. The unloading chain 61 is used to drive each unloading part 62 to be transported in the vertical direction. When the unloading part 62 rotates to the side of the unloading rack 60 facing the discharge port of the conveyor belt 1, the molded case circuit breaker base sent out from the discharge port of the conveyor belt 1 will move to the unloading part 62, and then the unloading part 62 will drive the assembled molded case circuit breaker base to be lifted upward.

[0033] like Figure 6 , Figure 7 As shown, the unloading mechanism 6 also includes a first lifting platform 63 located on one side of the unloading rack 60. The first lifting platform 63 is lifted and lowered along the height direction of the unloading rack 60 under the cooperation of the screw rod and the motor. A plurality of first storage seats 630 are stacked and fixed in sequence above the first lifting platform 63, and the feed port of the first storage seat 630 faces the unloading rack 60.

[0034] like Figure 6 , Figure 7 As shown, the unloading mechanism 6 also includes a first unloading assembly 64, which is used to push the molded case circuit breaker base that has risen to a specified height from the unloading member 62 into the first storage seat 630 at a specified height. The first unloading assembly 64 includes a mounting frame 11, a first screw rod 641 rotatably arranged on the mounting frame 11, a first unloading motor 640 fixedly arranged on the mounting frame 11, and a first unloading plate 642 threadedly connected to the outside of the first screw rod 641. The first unloading motor 640 is coaxially arranged with the first screw rod 641, and the first unloading motor 640 is used to drive the first screw rod 641 to rotate. As the first screw rod 641 rotates, the first unloading plate 642 will slide back and forth along the length direction of the first screw rod 641 under the limit of the mounting frame 11. The end of the first unloading plate 642 away from the first screw rod 641 extends to the side of the unloading member 62 located at the first unloading station.

[0035] like Figure 6 , Figure 7 As shown, when the molded case circuit breaker base is lifted by the unloading member 62 to the first unloading station, the first unloading motor 640 drives the first screw rod 641 to rotate. As the first screw rod 641 rotates, the first unloading plate 642 will push the molded case circuit breaker base to move into the first storage seat 630 at a specified height, and then the first unloading motor 640 reverses and resets the first unloading plate 642. When the molded case circuit breaker base fills the first storage seat 630, the first lifting platform 63 will drive the first storage seat 630 to move down layer by layer until the first storage seats 630 on each layer are filled with molded case circuit breaker bases.

[0036] like Figure 6 , Figure 7 As shown, the unloading mechanism 6 also includes a second lifting platform 65 located on the other side of the unloading member 62, and the first lifting platform 63 and the second lifting platform 65 are respectively located on the left and right sides of the unloading member 62. The lifting structure of the second lifting platform 65 is the same as the lifting structure of the first lifting platform 63, so it is not repeated. A plurality of second storage seats 66 are stacked and fixed on the second lifting platform 65 in sequence, and the feed port of the second storage seat 66 faces the unloading rack 60. The unloading mechanism 6 also includes a second unloading assembly 67, and the first unloading assembly 64 and the second unloading assembly 67 are arranged up and down.

[0037] like Figure 6 , Figure 7As shown, the second unloading assembly 67 includes a second screw rod 671 rotatably mounted on the mounting frame 11, a second unloading motor 670 fixedly mounted on the mounting frame 11, and a second unloading plate 672 threadedly connected to the outside of the second screw rod 671. The output shaft of the second unloading motor 670 is coaxially fixedly connected to the output shaft of the second screw rod 671, and the second unloading plate 672 reciprocates along the length direction of the second screw rod 671 under the limit of the mounting frame 11. The second screw rod 671 is used to push the molded case circuit breaker base that rises to the second unloading station from the unloading member 62 into the second storage seat 66 of each layer. The unloading principle of the second storage seat 66 is consistent with the unloading principle of the first storage seat 630, so it is not repeated.

[0038] like Figure 6 , Figure 7 As shown, when the first storage seats 630 of each layer are filled with molded case circuit breaker bases, the first unloading assembly 64 will stop running, and then the second unloading assembly 67 will start. At this time, the unloading work can be ensured to continue without affecting the normal assembly of copper parts, without stopping the unloading, and the assembly efficiency is guaranteed. After the staff takes out the first storage seat 630 filled with molded case circuit breaker bases from the first lifting platform 63, and then stacks the empty first storage seats 630, the reciprocating unloading can be realized. The setting of the second storage seat 66 can provide more sufficient operating time for the replacement of the first storage seat 630, facilitate the unloading of the staff, ensure production efficiency, and save time and effort in unloading.

[0039] The embodiment of the present application also discloses an assembly process of a molded case circuit breaker base copper part, using the above-mentioned molded case circuit breaker base copper part assembly machine, including: S1: placing the molded case circuit breaker bases to be assembled on the feeding end of the conveyor belt 1 in sequence; S2: Positioning, when the conveyor belt 1 conveys the molded case circuit breaker base to be assembled to the first lifting seat 4, the molded case circuit breaker base to be assembled is lifted to be flush with the assembly platform 20 by the first lifting seat 4; then the molded case circuit breaker base on the first lifting seat 4 is pushed onto the assembly platform 20 by the pusher 10, and then the positioning member 211 is inserted into the slot of the molded case circuit breaker base by the lifting cylinder 210, so that the molded case circuit breaker base is limited and fixed on the assembly platform 20; S3: Assembling, the copper parts are periodically assembled into the circuit breaker base located on the assembly platform 20 by the assembly mechanisms 3 on both sides; after the assembly is completed, the assembled molded case circuit breaker base is pushed out from the assembly platform 20 to the second lifting platform 5 by the pusher 10, and the second lifting platform 5 then moves the assembled molded case circuit breaker base from the assembly platform 20 to the conveyor belt 1; S4: Automatic unloading, the assembled molded case circuit breaker base is automatically loaded into the first storage seat 630 and the second storage seat 66 through the unloading mechanism 6.

[0040] The implementation principle is as follows: the first lifting seat 4 will, under the push of the cylinder, lift the molded case circuit breaker base to be assembled from the conveyor belt 1 upward until the bottom surface of the molded case circuit breaker base is flush with the upper surface of the assembly platform 20, at which time the molded case circuit breaker base is in the feeding station. Then the pusher 10 is used to push the molded case circuit breaker base in the feeding station into the assembly station of the assembly platform 20 in the horizontal direction. When the positioning member 211 is inserted into the slot of the molded case circuit breaker base under the drive of the lifting cylinder 210, the molded case circuit breaker base will be limited and fixed on the assembly station of the assembly platform 20. Then, the copper parts are periodically assembled into the molded case circuit breaker base located at the assembly station of the assembly platform 20 through the assembly mechanisms 3 on both sides.

[0041] When the molded case circuit breaker base has completed the assembly of the copper parts, the lifting cylinder 210 will drive the positioning member 211 to withdraw from the plug slot of the molded case circuit breaker base, and then the pusher 10 will start again and move the molded case circuit breaker base to be assembled in front from the first lifting seat 4 to the assembly platform 20. At this time, the assembled molded case circuit breaker base on the assembly platform 20 will be pushed onto the second lifting seat 5 in the raised state, and then the second lifting seat 5 will move the assembled molded case circuit breaker base from the assembly platform 20 back down to the conveyor belt 1.

[0042] When the molded case circuit breaker base is lifted to the first unloading station by the unloading member 62, the first unloading motor 640 drives the first screw rod 641 to rotate. As the first screw rod 641 rotates, the first unloading plate 642 pushes the molded case circuit breaker base to move into the first storage seat 630 at a specified height, and then the first unloading motor 640 reverses and resets the first unloading plate 642. When the molded case circuit breaker base fills the first storage seat 630, the first lifting platform 63 will drive the first storage seat 630 to move down layer by layer until the first storage seats 630 on each layer are filled with molded case circuit breaker bases.

[0043] When the first storage seats 630 on each layer are filled with molded case circuit breaker bases, the first unloading assembly 64 will stop running, and then the second unloading assembly 67 will start. At this time, the unloading work can be continued without affecting the normal assembly of copper parts, without stopping for unloading, thus ensuring the assembly efficiency.

[0044] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
