Description

Technical Field

[0001] The utility model relates to the field of turntable type automatic assembly equipment, in particular to an automatic feeding and forming mechanism for octagonal slices. Background Art

[0002] At present, turntable automatic assembly equipment has been widely used in the assembly of electronic components. There is a kind of fuse that needs to be assembled by turntable automatic assembly equipment. This fuse is also called a temperature fuse. For example, you can refer to the "temperature-sensitive particle type temperature fuse" with the Chinese utility model patent publication number CN111105964B and the "disc for temperature fuse and temperature fuse thereof" with the Chinese utility model patent publication number CN203521349U. Fig.12 As shown, during the assembly process, the octagonal piece 99 needs to be inserted (stuck) into the fuse housing 990, and in the subsequent process, the upper end opening of the fuse housing 990 is riveted and shrunk, as shown in FIG. Fig.13 As shown, the octagonal piece 99 is formed with eight teeth 991 (which can also be understood as "corners"). Before assembly, the octagonal piece 99 is in a straight state. When the octagonal piece 99 is inserted into the fuse housing 990, the inner wall of the fuse housing 990 presses the teeth 991 relatively inwardly, which will cause each tooth 991 to bend and deform upward, and the teeth 991 will be in close conductive contact with the inner wall of the fuse housing 990; the existing rotary table type automatic assembly equipment suction and insertion piece manipulator assembly, The sheet suction and insertion robot assembly is provided with a suction nozzle, and a countersunk hole is formed on the feeding jig, in which octagonal sheets 99 stacked approximately coaxially are placed. The suction nozzle is inserted into the countersunk hole, and the lower end of the suction nozzle is pressed against the uppermost octagonal sheet 99, and then the octagonal sheet 99 is adsorbed by negative pressure. The sheet suction and insertion robot assembly moves the suction nozzle and the octagonal sheet 99 together to the corresponding upper part of the fuse housing 990 on the jig on the assembly turntable, and then moves the suction nozzle downward, and the suction nozzle inserts the octagonal sheet 99 into the fuse housing 99 0, the outer diameter of the lower end of the suction nozzle is slightly smaller than the inner diameter of the fuse shell 990, and the outer diameter of the octagonal piece 99 is larger than the inner diameter of the fuse shell 990, so the tooth portion 991 of the octagonal piece 99 is squeezed inward by the inner edge of the upper port of the fuse shell 990 and bent upward to form; however, since the edge of the tooth portion 991 of the octagonal piece 99 will inevitably have some defects such as burrs or tiny gaps, the octagonal pieces 99 of adjacent layers in the above-mentioned feeding fixture may be hooked together, or when the suction nozzle adsorbs the octagonal piece 99, the octagonal piece 99 is twisted and deformed, resulting in unstable adsorption, and the octagonal piece 99 falls during the transfer process, resulting in an error in the number of octagonal pieces 99 in the fuse shell 990 (that is, not one octagonal piece 99), resulting in occasional assembled fuses being scrapped, which will have a serious impact on the safety of electrical equipment using the fuse, so it is necessary to improve the octagonal piece feeding and forming mechanism of the prior art.

DETAILED DESCRIPTION

[0026] The utility model is further described below in conjunction with the accompanying drawings.

[0027] The utility model of the octagonal slice automatic feeding and forming mechanism, such as Figures 1 to 3 As shown, it includes a feeding component 2 and a suction and insertion sheet robot component 6, as shown Figure 4 As shown, the feeding assembly 2 is provided with a feeding fixture 21, and a material storage countersunk hole 2101 is formed on the feeding fixture 21. The material storage countersunk hole 2101 is distributed in a rectangular array on the feeding fixture 21. The material storage countersunk hole 2101 has a large depth. Specifically, the step structure in the material storage countersunk hole 2101 supports the octagonal piece 99, and the octagonal piece 99 is roughly coaxially stacked in the material storage countersunk hole 2101. Figure 4As shown, the feeding assembly 2 also includes a feeding servo motor 22, which drives the feeding fixture 21 to move in a direction parallel to the tangent of the workstation turntable 1 through a corresponding ball screw pair. During this period, the feeding fixture 21 is guided by a corresponding linear guide pair.

[0028] like Figures 1 to 3 As shown, the automatic feeding and forming mechanism of octagonal slices of the present invention comprises a workstation turntable 1, a sheet loading robot assembly 3, a detection assembly 4 and a sheet cleaning assembly 5; the workstation turntable 1 is arranged outside the assembly turntable, that is, the workstation turntable 1 is located outside the assembly fixture 98 on the assembly turntable. Figure 8 As shown, a loading countersunk hole 101 adapted to the octagonal piece 99 is formed on the station turntable 1, and the upper part of the loading countersunk hole 101 is an inverted cone surface, which is convenient for the octagonal piece 99 to enter and exit the loading countersunk hole 101. Figure 1 As shown, the loading countersunk holes 101 are arranged in a group along the radial direction of the station turntable 1. For example, four loading countersunk holes 101 are arranged in a group radially, and the four groups of loading countersunk holes 101 are evenly distributed circumferentially. In other words, the station turntable 1 is a four-station turntable, such as Figure 3 As shown, for example, the workstation turntable 1 is driven to rotate by the turntable servo motor 11, and the rotation axis of the workstation turntable 1 is perpendicular to the horizontal plane. Figure 5 As shown, the sheet loading robot assembly 3 is provided with a sheet loading nozzle 31 for transferring the octagonal sheet 99 in the storage counterbore 2101 to the loading counterbore 101. Since the four loading counterbore 101 are radially arranged in a group, the four sheet loading nozzles 31 are also evenly spaced and arranged. The sheet loading nozzles 31 are extended in the up and down directions. Specifically, the sheet loading robot assembly 3 is also provided with a sheet loading lifting cylinder 32 and a sheet loading transverse cylinder 33. The sheet loading transverse cylinder 33 drives the sheet loading lifting cylinder 32 and the sheet loading nozzle 31 to move laterally (parallel to the radius of the workstation turntable 1). The sheet loading lifting cylinder 32 drives the sheet loading nozzle 31 to move up and down. The sheet loading lifting cylinder 32, the sheet loading transverse cylinder 33 and the feeding servo motor 22 form a three-axis robot mechanism. Figure 6 As shown, the detection assembly 4 is provided with a displacement sensor 41 for detecting the number of layers of the octagonal sheet 99 located in the loading counterbore 101. The displacement sensor 41 belongs to the prior art. For example, the Chinese invention patent publication number CN100578143C "A fiber grating displacement sensor" can be referred to. The displacement sensor 41 is provided with a probe rod 411 that can extend and reset automatically. The axis of the probe rod 411 is extended in the up-down direction. The displacement sensor 41 is arranged along the radial direction of the station turntable 1. Figure 7 and Fig. 9As shown, the sheet cleaning component 5 is provided with a sheet cleaning air nozzle 52 for blowing the octagonal sheets 99 in the loading counterbore 101 away from the loading counterbore 101 when the number of octagonal sheets 99 is incorrect. The sheet cleaning air nozzle 52 is arranged to blow upward, that is, the sheet cleaning air nozzle 52 is arranged coaxially with the corresponding loading counterbore 101 (when the loading counterbore 101 rotates to the workstation corresponding to the sheet cleaning component 5). The sheet cleaning air nozzle 52 is arranged below the workstation turntable 1. Since the loading counterbore 101 actually passes through the workstation turntable 1 from top to bottom, the sheet cleaning air nozzle 52 blows upward, so that the octagonal sheets 99 in the loading counterbore 101 can be blown away from the loading counterbore 101. The sheet cleaning air nozzle 52 is arranged radially along the workstation turntable 1. Fig. 9 As shown, the sheet suction and insertion robot assembly 6 is provided with a sheet suction nozzle 61 for moving and inserting the octagonal sheet 99 in the loading counterbore 101 into the fuse housing 990 on the assembly fixture 98. Specifically, the sheet suction and insertion robot assembly 6 is provided with a sheet lifting cylinder 62 and a sheet transverse movement cylinder 63. The sheet transverse movement cylinder 63 drives the sheet lifting cylinder 62 and the sheet suction nozzle 61 to move transversely, and the sheet lifting cylinder 62 drives the sheet suction nozzle 61 to move up and down. Since the four loading counterbore holes 101 are radially arranged in a group, the four sheet suction nozzles 61 are distributed at equal intervals accordingly.

[0029] The following briefly describes the working principle of the feeding and forming mechanism of the utility model: Figure 1 and Figure 2As shown, the upper sheet robot assembly 3 drives the upper sheet suction nozzle 31 to move to the top of the storage countersunk hole 2101 on the feeding fixture 21, and the upper sheet suction nozzle 31 moves downward, so that the lower end of the upper sheet suction nozzle 31 extends into the storage countersunk hole 2101 and abuts against the upper side of the octagonal sheet 99, and the upper sheet suction nozzle 31 uses negative pressure to hold the octagonal sheet 99, and the upper sheet robot assembly 3 drives the upper sheet suction nozzle 31 to move to the top of the loading countersunk hole 101 of the workstation turntable 1, and the upper sheet suction nozzle 31 moves downward to place the octagonal sheet 99 into the corresponding loading countersunk hole 101, so that four octagonal sheets 99 are loaded onto the workstation turntable 1 at one time, and then the turntable servo motor 11 drives the workstation turntable 1 to rotate 90° clockwise, so that the octagonal sheet 99 is transferred to the detection group At the workstation corresponding to component 4, the detection component 4 moves the displacement sensor 41 downward, and the probe rod 411 of the displacement sensor 41 is vertically inserted downward into the corresponding loading countersunk hole 101, so that the lower end of the probe rod 411 of the displacement sensor 41 contacts the top of the octagonal piece 99, and then the probe rod 411 of the displacement sensor 41 is blocked by the octagonal piece 99 and retracts upward relative to the displacement sensor 41 body. During each detection, the displacement sensor 41 body moves down to the same height position. If the number of octagonal pieces 99 in the loading countersunk hole 101 is wrong, for example, when two octagonal pieces 99 are stacked together, the probe rod 411 of the displacement sensor 41 is relatively more retracted into the displacement sensor 41 body. When the number of octagonal pieces 99 is zero, , the probe rod 411 of the displacement sensor 41 is relatively less retracted into the displacement sensor 41 body, so that the displacement sensor 41 can accurately sense the number of octagonal pieces 99 in the loading countersunk hole 101 through the above changes. After the measurement is completed, the displacement sensor 41 is raised and reset, and the station turntable 1 then transfers the octagonal pieces 99 that have been tested to the corresponding station of the cleaning component 5. If the detection component 4 previously detected that the number of octagonal pieces 99 in a group of loading countersunk holes 101 is one, then the control system will not control the cleaning air nozzle 52 to work. However, if the detection component 4 detects that the number of octagonal pieces 99 in any loading countersunk hole 101 is wrong, the control system will control the cleaning air nozzle 5 according to the detection result. 2 works, each cleaning air nozzle 52 simultaneously sprays compressed air upwards, so that the octagonal pieces 99 in each loading countersunk hole 101 are blown away, that is, even if the number of octagonal pieces 99 in a loading countersunk hole 101 is zero, the corresponding cleaning air nozzle 52 also sprays compressed air to prevent the octagonal pieces 99 in the loading countersunk hole 101 from flying into the loading countersunk hole 101 that originally had no octagonal pieces 99; the station turntable 1 continues to transfer the loading countersunk hole 101 to the station corresponding to the sheet suction and insertion manipulator assembly 6, if the detection assembly 4 does not detect an error in the number of octagonal pieces 99, the control system controls the sheet suction and insertion manipulator assembly 6 to work, and the sheet insertion nozzle 61 correspondingly sucks and holds the octagonal pieces 99 in the loading countersunk hole 101, such as Fig.10As shown, the insert sheet manipulator assembly 6 moves the insert sheet suction nozzle 61 and the octagonal sheet 99 to the top of the fuse housing 990 on the assembly fixture 98 on the assembly turntable, and the insert sheet suction nozzle 61 moves down. The lower end of the insert sheet suction nozzle 61 is inserted into the corresponding fuse housing 990, so that the tooth portion 991 of the octagonal sheet 99 is squeezed inward by the inner edge of the upper port of the fuse housing 990 and bent upward to form, and then the insert sheet suction nozzle 61 releases the octagonal sheet 99, and the insert sheet suction nozzle 61 moves up to leave the fuse housing 990, and the assembly turntable rotates to drive the assembly fixture 98 to transfer to the next assembly station. However, if the detection component 4 detects that the number of octagonal sheets 99 is wrong, the control system will not control the insert sheet manipulator assembly 6 to perform an action on the wrong group of loading countersunk holes 101, but the control system waits for the octagonal sheet 99 on the station turntable 1 without error. When all the octagonal pieces 99 in a row of storage countersunk holes 2101 of the feeding fixture 21 are sucked away, the feeding servo motor 22 drives the feeding fixture 21 to move one row spacing of the storage countersunk holes 2101. As can be seen from the above, the automatic feeding and forming mechanism of the utility model can prevent two or more octagonal pieces 99 from being inserted into the same fuse housing 990, and can also pre-exclude the defective octagonal pieces 99 that are twisted and deformed and cannot be well held, and avoid the octagonal pieces 99 from falling off during the process of transferring the octagonal pieces 99 to the assembly fixture 98 by the inserting nozzle 61, thereby avoiding the error in the number of octagonal pieces 99 in the fuse housing 990, which is conducive to improving the product quality of the fuse.

[0030] Furthermore, if Figure 6 As shown, the detection component 4 is provided with a sensor lifting cylinder 42, and the sensor lifting cylinder 42 drives the displacement sensor 41 to move up and down. Specifically, the displacement sensor 41 is installed on the same sensor lifting seat, and the piston rod of the sensor lifting cylinder 42 is installed and connected to the above-mentioned sensor lifting seat. The detection component 4 is provided with a measuring support rod 43 for supporting the bottom surface of the octagonal piece 99, and the measuring support rod 43 is arranged along the radial direction of the workstation turntable 1. The detection component 4 is provided with a support rod lifting cylinder 44, and the support rod lifting cylinder 44 drives the measuring support rod 43 to move up and down. Specifically, the measuring support rod 43 is inserted on the same support rod lifting seat, and the piston rod of the support rod lifting cylinder 44 is installed and connected to the above-mentioned support rod lifting seat. The above-mentioned sensor lifting seat and the above-mentioned support rod lifting seat are guided by the same vertically arranged linear guide pair. As shown Figure 6 As shown, the detection assembly 4 has a positioning plate 45 for limiting the position of the measurement support rod 43. The positioning plate 45 is fixedly installed on one side of the stand by screws. The positioning plate 45 is located between the above-mentioned sensor lifting seat and the above-mentioned support rod lifting seat. When the station turntable 1 transfers a group of loading countersunk holes 101 to the corresponding station of the detection assembly 4, the support rod lifting cylinder 44 first lifts the measurement support rod 43, as shown in FIG. Fig.14As shown, the upper end of the measuring support rod 43 is inserted upward into the lower part of the loading countersunk hole 101. When the upper end of the support rod lifting seat contacts the bottom of the positioning plate 45, the measuring support rod 43 is blocked and positioned. At this time, the upper end surface of the measuring support rod 43 is just flush with the internal step surface of the loading countersunk hole 101, that is, the bottom of the octagonal piece 99 is just against the upper end surface of the measuring support rod 43. Then the sensor lifting cylinder 42 lowers the displacement sensor 41, and the probe rod 411 is inserted into the upper part of the loading countersunk hole 101. Since the upper part of the octagonal piece 99 blocks the probe rod 411, the probe rod 411 is relatively retracted into the displacement sensor 41. The sensor lifting cylinder 42 can use an adjustable stroke cylinder, so that the displacement sensor 41 body can be moved down to the same height position each time; when there is only one (one layer) of octagonal piece 99 in the loading countersunk hole 101, the distance that the probe rod 411 is retracted relative to the inside of the displacement sensor 41 is used as the reference for the correct number of octagonal pieces 99, as shown in FIG. Fig.14 As shown, by providing the measuring support rod 43 to support the octagonal piece 99 , the octagonal piece 99 can be prevented from being pressed downward by the probe rod 411 , which is also beneficial for accurate measurement of the displacement sensor 41 .

[0031] Furthermore, if Figure 2 and Figure 7 As shown, the flake-clearing assembly 5 includes a flake-clearing pipe 51 and a collecting box 53. The collecting box 53 is arranged on the outside of the station turntable 1. One end of the flake-clearing pipe 51 can be correspondingly covered above the loading countersunk hole 101. That is to say, when the station turntable 1 rotates the loading countersunk hole 101 to the corresponding station of the flake-clearing assembly 5, the loading countersunk hole 101 is just located below one end of the flake-clearing pipe 51, and the other end of the flake-clearing pipe 51 is connected to the collecting box 53. The cross-section of the flake-clearing pipe 51 can be rectangular. When the flake-cleaning jet nozzle 52 blows up the octagonal flakes 99 in the loading counterbore 101 from bottom to top, the octagonal flakes 99 fly upward to one end of the flake-cleaning pipe 51, and the compressed air mixed with the octagonal flakes 99 is guided through the flake-cleaning pipe 51 to flow toward the other corresponding end of the flake-cleaning pipe 51, and finally the octagonal flakes 99 enter the collecting box 53. Through the above-mentioned arrangement, the octagonal flakes 99 can be properly collected after flying out of the loading counterbore 101, thereby preventing the octagonal flakes 99 from flying around and affecting the subsequent processes.

[0032] Furthermore, if Figure 2 and Fig.11As shown, the flake cleaning pipe 51 includes a flat pipe portion 511 and a drop pipe portion 512 for inserting into the upper part of the collecting box 53. The drop pipe portion 512 is arranged to be inclined downward, that is, the flat pipe portion 511 is arranged horizontally, and the upper end of the drop pipe portion 512 is connected to one end of the flat pipe portion 511, and the other end of the flat pipe portion 511 is closed. However, an octagonal piece entrance is formed on the lower side of the other end of the above-mentioned flat pipe portion 511, and the above-mentioned octagonal piece entrance can be aligned with the loading countersunk hole 101. In other words, "one end of the flake cleaning pipe 51 can cover the top of the loading countersunk hole 101", so the octagonal piece 99 is blown up and enters the above-mentioned flat pipe portion In the other end corresponding to 511, the upper wall of the material-dropping pipe part 512 is formed with an array of exhaust holes 5121, so that the compressed air mixed with the octagonal slices 99 flows through the flat pipe part 511. When the airflow is guided by the material-dropping pipe part 512 and turns downward, the airflow can be dispersed to the upper outer part of the film-clearing pipe 51 through the exhaust holes 5121, so that the airflow rushing into the collection box 53 is weakened, and the octagonal slices 99 entering the material-dropping pipe part 512 can fall into the collection box 53 by gravity because the material-dropping pipe part 512 is tilted downward, so that the airflow can avoid violently scouring the collection box 53 and causing the octagonal slices 99 in the collection box 53 to be blown away again. During this period, the diameter of the exhaust hole 5121 should be set smaller than the outer diameter of the octagonal slices 99.

[0033] Furthermore, if Fig. 9 As shown, the suction and insertion sheet manipulator assembly 6 is provided with a shell support fixture 64, such as Fig.10 As shown, the housing fixture 64 is formed with a housing through hole 641 for the upper end of the fuse housing 990 to be adapted and inserted relatively. The housing fixture 64 is in a plate shape. Fig. 9 As shown, the suction and insertion sheet manipulator assembly 6 is provided with a shell lifting cylinder 65, and the shell lifting cylinder 65 drives the shell fixture 64 to move up and down. Fig.10As shown, the insert suction nozzle 61 can pass through the corresponding shell through hole 641; through the above arrangement, when the station turntable 1 transfers the loading countersunk hole 101 and the octagonal piece 99 in the loading countersunk hole 101 to the corresponding station of the insert suction manipulator assembly 6, the shell lifting cylinder 65 first lowers the shell fixture 64, so that the bottom of the shell fixture 64 is close to the upper side of the corresponding assembly fixture 98, and at the same time, the upper part of the fuse housing 990 on the assembly fixture 98 is relatively inserted upward into the shell through hole 641, and then the insert lifting cylinder 62 and the insert transverse cylinder 63 are assembled. The moving inserting nozzle 61 is closed to hold the octagonal piece 99 in the loading counterbore 101 and transfer it to the top of the fuse housing 990, and then the inserting nozzle 61 is inserted into the supporting shell through hole 641. When the octagonal piece 99 is inserted into the fuse housing 990, since the inner wall of the supporting shell through hole 641 supports the wall of the fuse housing 990, it is prevented that the wall of the fuse housing 990 is supported to be partially bulged, and the upper part of the fuse housing 990 is also prevented from being pushed and bent, which is conducive to the stable process of inserting the octagonal piece 99 into the fuse housing 990. The upper and lower ends of the supporting shell through hole 641 are respectively formed with bell mouths, the lower bell mouth is used to guide the upper end of the fuse housing 990 to be relatively inserted, and the upper bell mouth is used to avoid the octagonal piece 99. When the octagonal piece 99 is assembled, the insert piece lifting cylinder 62 and the insert piece transverse movement cylinder 63 are combined to move the insert piece suction nozzle 61 to reset the insert piece suction nozzle 61, and then the shell supporting lifting cylinder 65 is reset to raise the shell supporting fixture 64.
