Figure 1 As shown, the contact support includes a bracket, three main contact pieces, three main springs, an auxiliary contact piece and an auxiliary spring. The bracket is provided with three main through holes arranged side by side and two auxiliary through holes distributed up and down. The contact support has two specifications of normally open and normally closed. The difference between the contact support structures of the two specifications lies in the different positions of the auxiliary through holes where the auxiliary contact pieces and the auxiliary springs are located.

[0034] The first loading assembly 1 adopts the loading method of the prior art, which includes a vibration plate 11, a conveyor belt 12 located above the vibration plate, a funnel-shaped silo 13 located above the conveyor belt, a conveyor path 14 connected to the discharge end of the vibration plate, and a manipulator 15 for clamping the bracket on the conveyor path. The bottom end of the silo 13 is provided with a through hole and is located above the conveyor belt 12;

[0035] Both the main transport component 2 and the auxiliary transport component 3 can adopt the existing transport mode. Both the main transport component 2 and the auxiliary transport component 3 include a plurality of workstations 21 distributed in a straight line and capable of carrying a bracket, a connecting member 22 for connecting the plurality of workstations 21 together, a lifting motor 23 for driving the connecting member 22 to move in a vertical direction, a linear motor 24 for driving the lifting motor 23 to move in a straight line in a horizontal direction, two rails 25 fixed relative to the workbench, and a travel switch 26 for limiting the travel of the connecting member 22.

[0036] The second feeding assembly 4 can be composed of an existing vibration plate, a conveyor and a straight vibrator. One end of the conveyor is connected to the outlet end of the vibration plate. The straight vibrator is positioned below the conveyor. Three troughs for transporting the main contact sheet are provided on the conveyor. The bottoms of the three troughs are all inclined.

[0037] The main clamping assembly 5 includes three main clamping jaws 51 for clamping the main contact piece, a main linear cylinder 52 and a main vertical cylinder 53. The three main clamping jaws 51 can adopt existing pneumatic clamping jaws. The body of the main vertical cylinder 53 is upright and positioned on the workbench. The body of the main linear cylinder 52 is fixedly connected to the output shaft of the main vertical cylinder 53. The three main clamping jaws 51 are all positioned on a plate and the plate is positioned on the output shaft of the main linear cylinder 52. The three main clamping jaws 51 are respectively opposite to the three material troughs. The clamping surfaces of the three main clamping jaws 51 for fitting with the main contact piece are cut so as to be tilted relative to the horizontal plane and the tilting degree is the same as the tilting degree of the bottom of the material trough. The maximum stroke position and the minimum stroke position of the main vertical motor 53 can make the main clamping jaws 51 correspond to the main through holes on the material trough and the bracket respectively.

[0038] The third loading assembly 6 and the fifth loading assembly 10 each include a material storage block 61, a plurality of feeding pipes 62, a compression cylinder 63, the same number of compression rods 64 as the feeding pipes 62, a pushing cylinder 65 and a shifting cylinder 66. The third loading assembly 6 is used for loading and installing the main spring. The number of the feeding pipes 62 and the compression rods 64 in the third loading assembly 6 are both three. The compression cylinder 63 is positioned on the workbench through a connecting frame. The three compression rods 64 are all fixedly connected to the output shaft of the compression cylinder 63. The cylinder body of the shifting cylinder 66 is fixedly connected to the workbench and is located on one side of the carrier rail 25. A flat plate located above the shifting cylinder 66 is fixedly connected to the output shaft of the shifting cylinder 66. The height of the flat plate is the same as that of the carrier rail 25. The pushing cylinder 65 and the material storage block 61 are both fixedly connected above the flat plate and distributed along the length direction of the flat plate. Three respectively corresponding material inlet holes 67 are directly opened from the end face of the material storage block 61 toward the pushing cylinder 65. The material channels 68 are connected one by one, the bottom surface of the material channel 68 is at a height greater than the height of the bubble point of the contact piece in the bracket, and the top surface of the material channel 68 is at a height less than the height of the bubble point on the top surface of the through hole of the bracket. The three material channels 68 all penetrate the material block 61. The output shaft of the push cylinder 65 is connected to three push rods 69, and the three push rods 69 are respectively inserted into the three material channels 68. The compression cylinder 63 is positioned on the workbench through the connecting frame. The compression cylinder 63 is located above the material block 61 and compresses The output shaft of the cylinder 63 faces the material block 61, and the three feed pipes 62 are positioned on the connecting frame and are perpendicular to the upper surface of the material block 61. The ports of the three feed pipes 62 away from the material block 61 are all connected to the same vibration plate through hoses, which are not drawn in the figure. The fifth feeding assembly 10 is used for feeding auxiliary springs, and the number of the feed pipe 62, compression rod 64, feeding hole 67, material channel 68 and push rod 69 in the fifth feeding assembly 10 is one;

[0039] The material moving component 7 can adopt an existing manipulator;

[0040] The fourth feeding assembly 8 can adopt the same structure as the second feeding assembly 4, and the auxiliary clamping assembly 9 can adopt the same structure as the main clamping assembly 5. Since the fourth feeding assembly 8 is used to feed the auxiliary contact sheet, and the auxiliary clamping assembly 9 is used to clamp the auxiliary contact sheet, the number of the material channel 68 in the fourth feeding assembly 8 is one, and the number of the main clamping jaws 51 in the auxiliary clamping assembly 9 is one;

[0041] In the initial state, the second loading assembly 4 and the fourth loading assembly 8 respectively transport the three main contact pieces and one auxiliary contact piece to one end of the corresponding trough, and one end of the three main contact pieces and one auxiliary contact piece are extended out of the trough and suspended in the air to remain stationary. The second loading assembly 4 and the fourth loading assembly 8 can both use the time interval set by the main controller to control whether the main contact piece and the auxiliary contact piece move to one end of the trough. The main contact piece and the auxiliary contact piece are both located on the bottom of the trough and are in an inclined state. The height of the main clamp 51 is the same as that of the trough. The feed hole 67 on the material holding block 61 is located directly below the feed pipe 62. The main spring and the auxiliary spring are vibrated by the vibration plate. The materials are fed into the corresponding feed holes 67. The distance between the bottom surface of the material channel 68 and the upper surface of the material block 61 can be designed to be equal to the length of the spring, or a component for dividing the spring in the feed pipe 62 is added so that the spring will not be located in the feed pipe 62 and the material block 21 at the same time. The two ends of the main spring and the auxiliary spring are respectively located in the feed hole 67 and the material channel 68. Taking the process of assembling a bracket as an example, the first step is to pour the bracket into the silo 13, and the bracket falls from the bottom of the silo 13 onto the conveyor belt. The conveyor belt transports the bracket to one end thereof, and the bracket falls into the vibration plate 11. The vibration plate 11 transports the bracket to the conveyor 14, and the robot 15 The bracket is moved to the rail 25 of the main transport component 2, and the carriers on both sides of the bracket are supported by the two rails 25 respectively; in the second step, under the action of the lifting motor 23 and the linear motor 24, the station 21 drives the bracket on the rail 25 to move between the main clamping component 5 and the second feeding component 4, and the main linear cylinder 52 drives the three main clamps 51 to move straight to the material channel and stop, and the three main clamps 51 start and clamp the main contact pieces at the ends of the three material troughs respectively. The three main contact pieces still remain in an inclined state. After being clamped in place, the main linear cylinder 52 resets, and the three main contact pieces detach from the corresponding material troughs. The straight vibrator starts to drive the main contact pieces in the material trough to continue Move to the end of the material trough until one end of the main contact piece is suspended in the air, and the straight vibrator stops to prepare for the next main contact piece to be clamped; the third step, the main vertical cylinder 53 drives the main linear cylinder 52 to move downward to the position where the height of the three main contact pieces is the same as the height of the main through holes in the bracket, the main vertical cylinder 53 stops, and the main linear cylinder 52 drives the three main contact pieces to move into place, and the three main contact pieces respectively penetrate the three main through holes on the bracket, and the three main clamps 51 release the main contact pieces. The three main contact pieces are restored to a horizontal state in the bracket under the action of gravity and are limited on the bracket, and then the main linear cylinder 52 and the main vertical cylinder 53 are reset successively to prepare for the next clamping;The fourth step is to operate the lifting motor 23 and the linear motor 24 again to transport the bracket equipped with the main contact sheet to the corresponding position of the material storage block 61. The ports of the three material channels 68 are respectively opposite to the three main through holes. The material moving cylinder 66 drives the pushing cylinder 65 and the material storage block 61 to move toward the bracket at the same time until the end surface of the flat plate touches the carrier rail 25. The material moving cylinder 66 stops running. The three material feeding holes 67 on the material storage block 61 correspond to the three compression rods 64 respectively. Then the compression cylinder 63 drives the three compression rods 64 to move downward. The three compression rods 64 first touch the corresponding main spring ends. As the compression rods 64 continue to move downward, the main springs are compressed until the main springs are completely located in the material channel 68. The compression cylinder 63 stops running, and the push rods 69 and the compression rods 64 do not interfere with each other. The fifth step is to drive the pushing cylinder 65 to drive the three push rods 69 to quickly push the corresponding main springs to move along the material channel 68 until the three springs break away from the material channel 68 and move forward. After the main springs are inserted into the corresponding main through holes, the pushing cylinder 65 stops, the three main springs all restore their elastic deformation and their two ends are respectively sleeved on the two bubble points in the corresponding main through holes and limited in the bracket, then the compression cylinder 63 drives the compression rod 64 to reset, and then the pushing cylinder 65 drives the three push rods 69 to reset, and the shifting cylinder 66 resets, and the main spring in the feeding pipe 62 falls into the material channel 68 through the feeding hole 67, so as to prepare for the next installation of the main spring; the sixth step, the lifting motor 23 and the linear motor 24 drive the station 21 to lift the bracket with the assembled main springs to move to the shifting assembly 7, and the shifting assembly 7 shifts the bracket with the main springs and the main contact piece to the carrier rail 25 of the auxiliary transport assembly 3, repeating the second to fifth steps, using the fourth loading assembly 8 and the auxiliary clamping assembly 9 to successively load the auxiliary contact piece and the auxiliary spring into the bracket, and finally using the shifting assembly 7 at the tail end of the auxiliary transport assembly 3 to remove and collect the assembled contact support;

[0042] Compared with the manual assembly of the contact support, this design realizes the automation of the contact support assembly. The main spring and the auxiliary spring are installed conveniently and accurately, which improves the production efficiency of the enterprise and reduces the labor cost of the enterprise.

[0043] For further optimization, refer to Fig. 9As shown, the third loading assembly 6 and the fifth loading assembly 10 also include a limit cylinder 60 arranged opposite to the container block 61 and fixed relative to the workbench, and a plurality of limit rods 601 positioned on the output shaft of the limit cylinder 60. The number of the limit rods 601 in the third loading assembly 6 is three, and the number of the limit rods 601 in the fifth loading assembly 10 is one. The limit rod 601 corresponds to the push rod 69. During the assembly process, the limit rod 601 will be driven by the limit cylinder 60 to insert into the main through hole before the push rod 69. Or in the auxiliary through hole, then the push rod 69 pushes the main spring or the auxiliary spring into the main through hole or the auxiliary through hole. After the main spring or the auxiliary spring touches the end of the limit rod 601, the push rod 69 stops pushing, and the main spring or the auxiliary spring recovers its deformation and is limited in the bracket. Such a design can provide a limit for the main spring or the auxiliary spring to avoid the main spring or the auxiliary spring flying out of the bracket due to inertia after being pushed quickly, thereby improving the accuracy of the positioning of the main spring or the auxiliary spring in the bracket and indirectly improving the qualified rate of assembly.

[0044] As a specific implementation method of the improvement, refer to Fig.12 As shown, the auxiliary clamping assembly 9 includes a second auxiliary clamping jaw 91, an auxiliary linear cylinder 92, an auxiliary vertical cylinder 93 and a rotary motor 94. The auxiliary vertical cylinder 93 stands on the workbench. The cylinder body of the auxiliary linear cylinder 92 is fixedly connected to the output shaft of the auxiliary vertical cylinder 93. The body of the rotary motor 94 is fixedly connected to the output shaft of the auxiliary linear cylinder 92. The second auxiliary clamping jaw 91 is fixedly connected to the output shaft of the rotary motor 94. The fourth feeding assembly 8 can be composed of an existing vibration plate, a straight vibrator and a conveyor. The bottom of the groove on the conveyor for accommodating the auxiliary contact piece can be a horizontal plane. The conveyor and the second auxiliary clamping jaw 91 are arranged opposite to each other. After one end of the auxiliary contact piece extends out of the conveyor and stops moving, the auxiliary linear cylinder 92 drives the rotary motor 94 to move toward the conveyor, and uses the second auxiliary clamping jaw 91 to clamp one end of the auxiliary contact piece. Then the auxiliary linear cylinder 92 is reset, the auxiliary contact piece leaves the conveying path, the auxiliary vertical cylinder 93 drives the second auxiliary clamp 91 to move to a position at the same height as the auxiliary through hole, and the rotating motor 94 drives the auxiliary contact piece to rotate a certain angle. As the auxiliary linear cylinder 92 drives the rotating motor 94 to move toward the bracket so that the auxiliary contact piece passes through the auxiliary through hole, the rotating motor 94 releases the auxiliary contact piece, and the auxiliary contact piece is limited in the bracket. The rotating motor 94 is reset during the resetting process of the auxiliary linear cylinder 92 and the auxiliary vertical cylinder 93 to prepare for clamping the auxiliary contact piece. Compared with the design in which the clamping surface of the second auxiliary clamp 91 and the bottom of the groove on the conveying path are both processed into inclined surfaces, this design can simplify the processing difficulty and size requirements of related components. At the same time, the rotating motor 94 can conveniently change the inclination state of the auxiliary contact piece, with high flexibility, which is convenient for the installation of the auxiliary contact piece.

[0045] As a specific implementation method of the improvement, since the contact support has two specifications, normally open and normally closed, the bracket needs to be placed upright and inverted during the production process of installing the auxiliary contact piece and the auxiliary spring. The bracket placed upright on the carrier rail 25 and the bracket placed inverted on the carrier rail 25 are at different heights above the upper surface of the carrier rail 25. After being lifted by the workstation 21, the auxiliary through holes of the auxiliary contact piece to be installed in the upright bracket and the inverted bracket are at different heights. Therefore, two production lines are required for the contact supports of the two specifications, which increases the cost of the enterprise. To solve this problem, refer to Fig.13 As shown, the auxiliary clamping assembly 9 also includes a positioning seat 95, a positioning cylinder 96 and a positioning cylinder 97. The positioning cylinder 96 is fixedly connected to the workbench and is respectively located on both sides of the auxiliary clamping assembly 9 with the second auxiliary clamping jaw 91. The height of the positioning cylinder 96 is higher than the height of the rail 25. The positioning seat 95 and the positioning cylinder 97 are both positioned on the output shaft of the positioning cylinder 96. The positioning seat 95 is provided with a positioning groove 951 for the bracket to be inserted. The positioning groove 951 is provided with a chamfered surface 952 that can slide relative to the edge of the bracket on a groove wall in the length direction of the bracket. The chamfered surface The distance between 952 and the opposite groove wall gradually decreases along the direction in which the bracket is inserted into the alignment groove 951. A top piece 953 capable of contacting the side wall of the bracket is elastically connected to the groove wall of the alignment groove 951 relative to the groove wall where the chamfered surface 952 is located. One end of the top piece 953 penetrates the groove wall of the alignment groove 951. A spring sleeved with the outside of the top piece 953 is arranged in the alignment groove 951. The alignment groove 951 faces the bracket on the carrier rail 25. The positioning cylinder 97 is located above the alignment groove 951 and its output shaft faces the alignment groove 951. The fourth feeding assembly 8 can be located above the positioning cylinder 97.

[0046] There are two fifth loading assemblies 10 and they are distributed along the length direction of the rail 25. The push rods 69 of the two fifth loading assemblies 10 are at different heights and correspond to the auxiliary through holes of the upright bracket and the auxiliary through holes of the inverted bracket equipped with auxiliary contact sheets, respectively. During the processing, the upright or inverted bracket will be lifted up by the workstation 21 and moved to the front of the alignment seat 95 along with the workstation 21. When the workstation 21 is still lifting the bracket, the alignment cylinder 97 drives the alignment seat 4 to move toward the bracket. As the bracket slides relative to the beveled surface 952 and enters the alignment groove 951, the bracket moves in the length direction of the rail 25. The other side of the bracket contacts the top piece 953 and pushes the top piece 43 to move out of the alignment groove 41. The spring is compressed until the edge of the bracket is separated from the beveled surface 952, the bracket enters the alignment groove 951 and no longer moves. The bracket is clamped by the top piece 953 and the groove wall of the alignment groove 951, and then the workstation 21 moves downward and separates from the bracket. , and then the bracket is pushed downward by the output shaft of the positioning cylinder 97 so that the auxiliary through hole on the bracket is at a fixed height.
