Detailed implementation manners

[0038] The following further describes the present application in detail with reference to the accompanying drawings.

[0039] An embodiment of the present application discloses a copper part assembling machine for a plastic case circuit breaker base.

[0040] Figure 8 This is the plastic case circuit breaker base after the copper parts are assembled in the present application, including a socket strip slot 7 and copper parts 8 assembled on both sides of the socket strip slot 7. For the socket strip slot 7 and the copper parts 8 involved in the subsequent text, please refer to them together Figure 8 .

[0041] Refer to Figure 1 , Figure 2 , the copper part assembling machine for the plastic case circuit breaker base includes a conveyor belt 1, a positioning mechanism 2, an assembly mechanism 3, a first lifting seat 4, a second lifting seat 5 and an unloading mechanism 6. The conveyor belt 1 is driven by a motor, and the conveyor belt 1 is used to convey the plastic case circuit breaker base backward. The positioning mechanism 2 includes an assembly platform 20, the assembly platform 20 is erected above the conveyor belt 1, and a positioning component 21 is arranged on the assembly platform 20. The positioning component 21 is used to limit and fix the plastic case circuit breaker base at the assembly station of the assembly platform 20.

[0042] Such as Figure 2 , Figure 3As shown in the figure, the positioning component 21 includes a lifting cylinder 210 fixedly installed above the assembly platform 20. The piston rod of the lifting cylinder 210 is vertically downward, and a positioning member 211 facing the assembly platform 20 is fixedly installed on the piston rod of the lifting cylinder 210. The positioning member 211 is used to insert into the socket groove of the plastic case circuit breaker base from top to bottom. When the positioning member 211 is inserted into the socket groove of the plastic case circuit breaker base under the drive of the lifting cylinder 210, the plastic case circuit breaker base will be limited and fixed at the assembly station of the assembly platform 20.

[0043] As Figure 2 , Figure 3 shown in the figure, 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 bottoms 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.

[0044] As Figure 2 , Figure 3 shown in the figure, since the interval height formed between the assembly platform 20 and the upper surface of the conveyor belt 1 is less than the height of the plastic case circuit breaker base, when the plastic case circuit breaker base to be assembled moves to directly above the first lifting seat 4 under the conveyance of the conveyor belt 1, the plastic case circuit breaker base will be limited on the first lifting seat 4 by the assembly platform 20, and the plastic case circuit breaker base cannot pass smoothly under the assembly platform 20. Subsequently, the first lifting seat 4 will be pushed by the cylinder to lift the plastic case circuit breaker base to be assembled upward from the conveyor belt 1 until the bottom surface of the plastic case circuit breaker base is flush with the upper surface of the assembly platform 20. At this time, the plastic case circuit breaker base is at the feeding station.

[0045] As Figure 2 , Figure 3 shown in the figure, it further includes a pusher 10 installed 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 plastic case circuit breaker base at the feeding station horizontally into the assembly station of the assembly platform 20.

[0046] As Figure 3 , Figure 4 shown in the figure, the assembly mechanism 3 is symmetrically arranged on the left and right sides of the assembly platform 20. The assembly mechanism 3 is used to periodically assemble copper parts into the plastic case circuit breaker base located at the assembly station of the assembly platform 20. The number of copper parts to be assembled on the same side of the plastic case circuit breaker base is three. Therefore, the assembly mechanism 3 will synchronously complete the assembly work of three copper parts on the same side each time.

[0047] As Figure 3 ,Figure 4 As shown in the figure, the assembly mechanism 3 includes an assembly base 30. An assembly cylinder 31 is arranged on the assembly base 30. A push plate 32 is fixedly installed on the piston rod of the assembly cylinder 31. The assembly cylinder 31 is used to push the push plate 32 to reciprocate horizontally along the direction of inserting the copper parts into the socket slots of the plastic case circuit breaker base. Each time the push plate 32 assembles three copper parts on the same side synchronously. Three assembly slots 33 are also arranged on the assembly base 30, and the assembly slots 33 are in one-to-one correspondence with the socket slots of the plastic case circuit breaker base to be assembled at the assembly station. When the three copper parts on the same side are respectively moved to the openings of their corresponding assembly slots 33, the push plate 32 will be driven by the piston rod of the assembly cylinder 31 to push the three copper parts into the socket slots of the plastic case circuit breaker base to be assembled along their respective assembly slots 33, thus completing the assembly of the copper parts. During assembly, the two-sided assembly mechanisms 3 will achieve synchronous assembly, greatly improving the assembly efficiency.

[0048] As Figure 1 、 Figure 4 shown in the figure, the assembly mechanism 3 further includes two copper part vibrating bowls 34. The copper part vibrating bowls 34 sequentially convey the copper parts to their corresponding assembly bases 30 through a material channel. A transfer cylinder 35 is mounted on the assembly base 30. A transfer seat 36 is fixedly arranged on the piston rod of the transfer cylinder 35. The transfer cylinder 35 is used to drive the transfer seat 36 to reciprocate along the feeding direction of the material channel of the copper part vibrating bowl 34.

[0049] As Figure 3 、 Figure 4 shown in the figure, two adjusting cylinders 360 are fixedly installed on the transfer seat 36. A transfer member 37 is fixedly arranged on the piston rod of the adjusting cylinder 360. A transfer post 38 is fixedly arranged at the bottom of the transfer seat 36. The transfer members 37 are symmetrically arranged on the front and rear sides of the transfer post 38. The transfer members 37 and the transfer post 38 are used to insert into the respective corresponding copper part wiring holes, and under the push of the piston rod of the transfer cylinder 35, the three copper parts are synchronously moved to the openings of the respective assembly slots 33.

[0050] As Figure 3 、 Figure 4As shown in the figure, the adjusting cylinder 360 is used to adjust the interval between the two material transfer members 37 and the material transfer column 38 on both sides. A driving cylinder 39 is also provided on the assembly seat 30. The material transfer cylinder 35 is installed on the piston rod of the driving cylinder 39. The driving cylinder 39 is used to drive the material transfer seat 36 to move up and down in the vertical direction. When the material transfer members 37 and the material transfer column 38 move to directly above the material channel of the copper part vibrating disk 34, at this time, the two material transfer members 37 on both sides will move closer to the material transfer column 38 under the drive of their respective adjusting cylinders 360. Subsequently, the driving cylinder 39 will drive the material transfer seat 36 to descend. At this time, the two material transfer members 37 and the material transfer column 38 will be inserted downward into the respective copper part wiring holes on their opposite sides. Subsequently, under the drive of the material transfer cylinder 35, the three copper parts will be synchronously removed from the material channel of the copper part vibrating disk 34. Finally, under the adjustment of the adjusting cylinder 360, the copper parts will respectively move to the openings of their respective corresponding assembly grooves 33. Subsequently, the driving cylinder 39 will drive the material transfer seat 36 to move upward. Then, the material transfer cylinder 35 will drive the material transfer seat 36 to retreat and reset to prepare for a new round of material transfer work.

[0051] As Figure 3 , Figure 4 shown, after the copper parts are assembled on the plastic case circuit breaker base, the lifting cylinder 210 will drive the positioning member 211 to withdraw from the socket slot of the plastic case circuit breaker base. Then, the pusher 10 will start again and move the plastic case circuit breaker base to be assembled in front from the first lifting seat 4 onto the assembly platform 20. At this time, the plastic case circuit breaker base assembled on the assembly platform 20 will be pushed onto the second lifting seat 5 in the lifted state. Subsequently, the second lifting seat 5 will move the assembled plastic case circuit breaker base from the assembly platform 20 back down to the conveyor belt 1.

[0052] As Figure 5 , Figure 6 shown, the unloading mechanism 6 includes an unloading rack 60 located on one side of the discharge port of the conveyor belt 1. The unloading rack 60 is vertically arranged. An unloading chain 61 is rotatably arranged on the unloading rack 60 through a motor. A plurality of unloading members 62 are fixedly arranged on the unloading chain 61 at intervals in the rotation direction of the unloading chain 61. The unloading chain 61 is used to drive each unloading member 62 to convey in the vertical direction. When the unloading member 62 rotates to the side of the unloading rack 60 facing the discharge port of the conveyor belt 1, the plastic case circuit breaker base sent out from the discharge port of the conveyor belt 1 will move onto the unloading member 62. Subsequently, the unloading member 62 will drive the assembled plastic case circuit breaker base to lift upward.

[0053] As Figure 6 , Figure 7 shown, the unloading mechanism 6 further includes a first lifting platform 63 located on one side of the unloading rack 60. The first lifting platform 63 moves up and down along the height direction of the unloading rack 60 under the cooperation of a lead screw and a motor. A plurality of first storage seats 630 are stacked and fixed in sequence above the first lifting platform 63. The feeding ports of the first storage seats 630 face the unloading rack 60.

[0054] As Figure 6 , Figure 7 shown, the unloading mechanism 6 further includes a first unloading component 64. The first unloading component 64 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 receiving seat 630 at the specified height. The first unloading component 64 includes a mounting frame 11, a first lead screw 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 lead screw 641. The first unloading motor 640 and the first lead screw 641 are coaxially arranged, and the first unloading motor 640 is used to drive the first lead screw 641 to rotate. With the rotation of the first lead screw 641, the first unloading plate 642 will reciprocally slide along the length direction of the first lead screw 641 under the limitation of the mounting frame 11. One end of the first unloading plate 642 away from the first lead screw 641 extends to one side of the unloading member 62 at the first unloading station.

[0055] As Figure 6 , Figure 7 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 lead screw 641 to rotate. With the rotation of the first lead screw 641, the first unloading plate 642 will push the molded case circuit breaker base into the first receiving seat 630 at the specified height. Subsequently, the first unloading motor 640 reverses and resets the first unloading plate 642. When the first receiving seat 630 is filled with the molded case circuit breaker base, the first lifting table 63 will drive the first receiving seat 630 to move down layer by layer until each layer of the first receiving seat 630 is filled with the molded case circuit breaker base.

[0056] As Figure 6 , Figure 7 shown, the unloading mechanism 6 further includes a second lifting table 65 located on the other side of the unloading member 62. The first lifting table 63 and the second lifting table 65 are respectively located on the left and right sides of the unloading member 62. The lifting structure of the second lifting table 65 is the same as that of the first lifting table 63, so it will not be described in detail here. A plurality of second receiving seats 66 are sequentially stacked and fixed on the second lifting table 65, and the feeding ports of the second receiving seats 66 face the unloading rack 60. The unloading mechanism 6 further includes a second unloading component 67. The first unloading component 64 and the second unloading component 67 are arranged up and down.

[0057] As Figure 6 , Figure 7As shown in the figure, the second unloading assembly 67 includes a second lead screw 671 rotatably arranged on the mounting frame 11, a second unloading motor 670 fixedly installed on the mounting frame 11, and a second unloading plate 672 threadedly connected to the outside of the second lead screw 671. The output shaft of the second unloading motor 670 is coaxially and fixedly connected to the output shaft of the second lead screw 671. The second unloading plate 672 reciprocally slides along the length direction of the second lead screw 671 under the limitation of the mounting frame 11. The second lead screw 671 is used to push the plastic case circuit breaker base that has risen to the second unloading station from the unloading member 62 into each layer of the second receiving seat 66. The unloading principle of the second receiving seat 66 is the same as that of the first receiving seat 630, so it will not be elaborated here.

[0058] As Figure 6 , Figure 7 shown in the figure, when each layer of the first receiving seat 630 is filled with the plastic case circuit breaker base, at this time the first unloading assembly 64 will stop running, and then the second unloading assembly 67 will start. At this time, it can ensure the continuous progress of the unloading work without affecting the normal assembly of the copper parts, without the need to stop the machine for unloading, thus ensuring the assembly efficiency. After the staff takes out the first receiving seat 630 filled with the plastic case circuit breaker base from the first lifting platform 63 and stacks the empty first receiving seats 630, the cyclic unloading can be realized. The setting of the second receiving seat 66 can provide more sufficient operation time for the replacement of the first receiving seat 630, facilitating the unloading of the staff, ensuring the production efficiency, and making the unloading work more time-saving and labor-saving.

[0059] The embodiment of the present application also discloses an assembly process for the copper parts of the plastic case circuit breaker base. Using the above-mentioned plastic case circuit breaker base copper part assembly machine, it includes:

[0060] S1: Feeding, placing the plastic case circuit breaker bases to be assembled in sequence at the feeding end of the conveyor belt 1;

[0061] S2: Positioning, when the conveyor belt 1 conveys the plastic case circuit breaker base to be assembled to the first lifting seat 4, the first lifting seat 4 lifts the plastic case circuit breaker base to be assembled to be flush with the assembly platform 20; then the pusher 10 pushes the plastic case circuit breaker base on the first lifting seat 4 onto the assembly platform 20, and then the lifting cylinder 210 inserts the positioning member 211 into the socket slot of the plastic case circuit breaker base to limit and fix the plastic case circuit breaker base on the assembly platform 20;

[0062] S3: Assembly, periodically assembling the copper parts into the circuit breaker base located on the assembly platform 20 through the two-side assembly mechanisms 3; after the assembly is completed, the pusher 10 pushes the assembled plastic case circuit breaker base out of the assembly platform 20 onto the second lifting seat 5, and the second lifting seat 5 then moves the assembled plastic case circuit breaker base down from the assembly platform 20 to the conveyor belt 1;

[0063] S4: Automatic unloading. The assembled plastic case circuit breaker base is automatically loaded into the first storage seat 630 and the second storage seat 66 through the unloading mechanism 6.

[0064] The implementation principle is as follows: The first lifting seat 4 will be pushed by the cylinder to lift the plastic case circuit breaker base to be assembled upward from the conveyor belt 1 until the bottom surface of the plastic case circuit breaker base is flush with the upper surface of the assembly platform 20. At this time, the plastic case circuit breaker base is at the feeding station. Subsequently, the pusher 10 is used to push the plastic case circuit breaker base at the feeding station horizontally onto the assembly station of the assembly platform 20. When the positioning member 211 is inserted into the socket slot of the plastic case circuit breaker base under the drive of the lifting cylinder 210, the plastic case circuit breaker base will be limited and fixed at the assembly station of the assembly platform 20. Then, the copper parts are periodically assembled into the plastic case circuit breaker base located at the assembly station of the assembly platform 20 through the two-side assembly mechanisms 3.

[0065] After the plastic 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 socket slot of the plastic case circuit breaker base. Then, the pusher 10 will be started again and move the plastic case circuit breaker base to be assembled in front from the first lifting seat 4 onto the assembly platform 20. At this time, the assembled plastic case circuit breaker base on the assembly platform 20 will be pushed onto the second lifting seat 5 in the lifted state. Subsequently, the second lifting seat 5 will move the assembled plastic case circuit breaker base from the assembly platform 20 back down to the conveyor belt 1.

[0066] When the plastic case circuit breaker base is lifted to the first unloading station by the unloader 62, the first unloading motor 640 drives the first lead screw 641 to rotate. As the first lead screw 641 rotates, the first unloading plate 642 will push the plastic case circuit breaker base into the first storage seat 630 at the specified height. Subsequently, the first unloading motor 640 rotates in reverse and resets the first unloading plate 642. When the first storage seat 630 is filled with the plastic case circuit breaker base, the first lifting platform 63 will drive the first storage seat 630 to move down layer by layer until each layer of the first storage seat 630 is filled with the plastic case circuit breaker base.

[0067] When each layer of the first storage seat 630 is filled with the plastic case circuit breaker base, at this time, the first unloading assembly 64 will stop operating, and then the second unloading assembly 67 will be started. At this time, it can ensure the continuous progress of the unloading work without affecting the normal assembly of the copper parts, without the need to stop the machine for unloading, and ensure the assembly efficiency.

[0068] The above are all the preferred embodiments of this application. The protection scope of this application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
