Description

Technical Field

[0001] This invention relates to the field of non-standard automated equipment technology, specifically an automatic assembly machine. Background Technology

[0002] like Figure 1 The workpiece structure shown comprises a housing 1, a cap 2, steel balls, and springs. Assembly requires a specific sequence of operations: first, a certain number of steel balls (e.g., 45, 60, or 75) are filled into the housing 1; then, the springs are installed inside the housing 1; and finally, the cap 2 is pressed onto the housing 1. In traditional assembly processes, the placement of the steel balls, the installation of the springs, and the pressing of the cap 2 are typically done manually. In the steel ball assembly step, workers must first accurately sort out the corresponding number of steel balls according to the workpiece design requirements, and then manually place them one by one into the workpiece. However, this work mode is not only time-consuming, but also prone to counting errors during the counting and filling of steel balls, which undoubtedly fails to meet the high standards of accuracy and efficiency required for large-scale mass production. Summary of the Invention

Detailed Implementation

[0066] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0067] An automatic assembly machine includes: a workbench 3 with a plurality of workstations 4 arranged linearly thereon; a housing feeding unit 5 having a positioning seat 6 disposed on the workbench 3, the housing feeding unit 5 being used to place housings 1 to be assembled on the positioning seat 6; a steel ball feeding unit 7 having a hopper 8, a distributing component 9, and a picking component 10, the hopper 8 being disposed above the workbench 3 and containing steel balls to be assembled, the distributing component 9 being movably inserted into the hopper 8 for quantitatively separating the steel balls in the hopper 8, and the picking component 10 being movably disposed above one of the workstations 4 for transporting the steel balls on the distributing component 9 to the housings 1 placed in the workstation 4; and a spring feeding unit 11 disposed to the side of the steel ball feeding unit 7. Unit 11 is used to provide springs to be assembled for the housing 1 in the working position 4; cap feeding unit 12 is located on the side of the spring feeding unit 11 away from the steel ball feeding unit 7, and the cap feeding unit 12 is used to provide caps 2 to be assembled for the housing 1 in the working position 4; detection unit 13 is located on the side of the cap feeding unit 12 away from the spring feeding unit 11, and the detection unit 13 is used to detect assembled workpieces; conveying unit 14 is located on the workbench 3, and the conveying unit 14 is used for conveying positioning seats 6 and semi-finished and finished products on each of the working positions 4; sorting unit 56 is located on the workbench 3 and to the side of the detection unit 13, and the sorting unit 56 is used to sort qualified and unqualified workpieces.

[0068] Based on the above embodiments, an exemplary structure of this solution is as follows: Figures 1 to 11 As shown, each of the following units—shell loading unit 5, steel ball loading unit 7, spring loading unit 11, cap loading unit 12, and detection unit 13—has a working position 4 on one side. During operation, the shell loading unit 5 first transports the shell 1 to be assembled to the positioning seat 6, and then the transport unit 14 transports the shell 1 from the positioning seat 6 to… Figure 2At the leftmost workstation 4, after the housing 1 is placed, the material distributor 9 on the steel ball feeding unit 7 moves within the hopper 8, separating a certain number of steel balls. Then, the material picker 10 moves and grabs the steel balls from the material distributor 9 into the housing 1, completing the quantitative loading of steel balls. After the steel balls are loaded, the conveying unit 14 transports the housing 1 containing the steel balls to the workstation 4 located to the side of the spring feeding unit 11. At this time, the spring feeding unit 11 loads springs into the housing 1 containing the steel balls. Then, the conveying unit 14 moves again to drive the steel balls and springs. The housing 1 is moved to the working position 4 located to the side of the cap feeding unit 12. At this time, the cap feeding unit 12 presses the cap 2 into the housing 1. Then the conveying unit 14 moves again to transport the housing 1 with the cap 2 assembled to the working position 4 to the side of the detection unit 13 to detect the assembled workpiece. Finally, the conveying unit 14 transports the detected workpiece to the sorting unit 56. The sorting unit 56 sorts the workpieces according to the detection results of the detection unit 13, and distinguishes between qualified and unqualified workpieces, thus completing the entire assembly process of the workpiece.

[0069] In this solution, the assembly and inspection of workpieces are automatically completed through the cooperation of the shell feeding unit 5, the steel ball feeding unit 7, the spring feeding unit 11, the cap feeding unit 12, the detection unit 13 and the conveying unit 14, which improves the assembly efficiency and accuracy of the workpieces. In addition, the steel balls are automatically and quantitatively removed from the hopper 8 by the material distribution unit 9 and the material picking unit 10 to ensure the accuracy of the number of steel balls assembled.

[0070] In this scheme, the material distribution component 9 is provided with a material distribution area 15, and the material distribution area 15 is provided with a number of positioning holes 16 for accommodating steel balls. The steel balls can be fixed in the positioning holes 16 when the material distribution component 9 moves from the bottom of the hopper 8 toward the opening of the hopper 8.

[0071] The steel balls to be filled are stored in the hopper 8. During operation, the dispensing component 9 first moves toward the side of the hopper 8 with an opening. During this process, the positioning holes 16 are used to limit the steel balls so that the dispensing area 15 can grab a preset number of steel balls, thereby achieving the purpose of quantitatively grabbing steel balls. Preferably, there are five dispensing areas 15 evenly distributed on the dispensing component 9, and each dispensing area 15 is provided with fifteen positioning holes 16. Therefore, each dispensing area 15 can hold 15 steel balls, and the entire dispensing component 9 can take out a maximum of 75 steel balls from the hopper 8 in a single operation.

[0072] The positioning hole 16 is a hole-like structure located on the side of the material distribution component 9 facing the opening of the hopper 8. When the diameter of the positioning hole 16 is slightly larger than the diameter of the steel ball, it should be ensured that part of the surface of the steel ball is exposed outside the positioning hole 16 so that the material handling component 10 can easily remove the steel ball from the positioning hole 16. If the diameter of the positioning hole 16 is smaller than the diameter of the steel ball, the diameter of the positioning hole 16 needs to be greater than one-quarter of the diameter of the steel ball to ensure that the steel ball in the positioning hole 16 cannot be separated from the material distribution component 9 during its movement.

[0073] Correspondingly, the material taking part 10 is provided with a material taking hole 17 corresponding to the positioning hole 16 and an air pipe connector 18 for connecting an air source. The air pipe connector 18 is located on the other side of the material taking part 10 where the material taking hole 17 is provided and is connected to the material taking hole 17. When the air pipe connector 18 is connected to the air source, it is used to provide suction force for the material taking hole 17 to adsorb the steel balls on the material distribution area 15.

[0074] The picking hole 17 is a through hole provided on the picking member 10. In order to optimize the gripping effect of the picking member 10 on the steel ball, the diameter of the through hole is preferably slightly smaller than the diameter of the steel ball. In this way, when the air pipe connector 18 is connected to the air source, a negative pressure will be generated in the through hole, which is conducive to sucking the steel ball up from the positioning hole 16. Of course, during operation, not all picking holes 17 need to be working. When 45 or 60 workpieces are picked up, some picking holes 17 on the picking member 10 do not need to be connected to the air source.

[0075] In addition, the steel ball feeding unit 7 also includes: a first fixed frame 19, with a hopper 8 mounted on the first fixed frame 19; a first driving member 20, which is vertically mounted on the first fixed frame 19 and located below the hopper 8, with a distributing member 9 connected to the output end of the first driving member 20, the first driving member 20 being used to drive the distributing member 9 to move within the hopper 8; and a second driving member 21, which is horizontally mounted on the first fixed frame 19 and located to the side of the hopper 8, with a pusher block 22 mounted on the output end of the second driving member 21. The pusher block 22 is made of soft material and is movably mounted within the hopper 8 along a direction perpendicular to the movement direction of the distributing member 9. The side of the distributing member 9 with the positioning hole 16 is located on the movement path of the pusher block 22, and the pusher block 22 is used to distribute the material. The steel balls in the positioning hole 16 are pushed away from the material distribution component 9; the third drive component 23 is horizontally set on the first fixed frame 19 and above the hopper 8; the fourth drive component 24 is vertically set at the output end of the third drive component 23, and the material picking component 10 is connected to the output end of the fourth drive component 24; the fifth drive component 25 is vertically set on the first fixed frame 19 and below the fourth drive component 24, and the output end of the fifth drive component 25 is connected to the hopper 26. The fifth drive component 25 is used to drive the hopper 26 to move closer to or further away from the material picking component 10. The hopper 26 is located on the moving path of the material picking component 10 and is used to receive the steel balls on the material picking component 10; the sensor 27 is used to detect whether steel balls are adsorbed on the material picking component 10.

[0076] The main function of the pusher block 22 is to clean the steel balls in the non-positioning holes 16 on the surface of the material distribution component 9. In order to prevent the pusher block 22 from accidentally pushing out the steel balls in the positioning holes 16, this solution uses soft materials such as soft rubber or foam to make the pusher block 22.

[0077] During operation, the first drive unit 20 moves the material distribution component 9 toward the side of the hopper 8 with an opening. At this time, most of the steel balls slide off the surface of the material distribution component 9, some steel balls are stuck in the preset positioning holes 16, and other steel balls are located in other positions on the surface of the material distribution component 9. When the material distribution component 9 moves to the running trajectory of the pusher block 22, the second drive unit 21 moves the pusher block 22 to sweep away the steel balls on the material distribution component 9 that are outside the positioning holes 16. After that, the second drive unit 21 drives the pusher block 22 to perform a reset action so that the material picking component 10 can smoothly pick up the steel balls on the material distribution component 9. Next, the third drive unit 23 and the fourth drive unit 24 drive the material picker 10 to remove the steel ball placed in the positioning hole 16 and move it above the hopper 26. At this time, the fifth drive unit 25 drives the hopper 26 to rise and actively receive the steel ball on the material picker 10. While the fifth drive unit 25 drives the hopper 26 to rise, the conveying unit 14 transports the housing 1 to the working position 4 on one side of the steel ball feeding unit 7. At this time, the outlet of the hopper 26 is facing the housing 1. The material picker 10 releases its adsorption on the steel ball. Under the action of its own gravity, the steel ball flows into the housing 1 after passing through the hopper 26, thus completing the filling of the steel ball.

[0078] Sensor 27 is configured to monitor changes in gas pressure within the air connector 18. When the positioning hole 16 on the material distributor 9 is filled with steel balls, the material receiving hole 17 of the material receiving component 10 will be blocked by the steel balls. At this time, there is no air leakage between the air connector 18 and the air source, and sensor 27 will not alarm. However, when the material receiving hole 17 is not completely filled with steel balls, the air connector 18 comes into contact with the outside atmosphere when the material receiving component 10 grasps the material, and sensor 27 will detect a leakage signal.

[0079] In addition, the spring feeding unit 11 includes: a first vibratory feeder 28, which is disposed on the side of the worktable 3; a sixth driving member 29, which is horizontally disposed on the worktable 3; a first moving block 30, which is connected to the output end of the sixth driving member 29, and the first moving block 30 is provided with a first through hole 31 movably disposed above the working position 4; a seventh driving member 32, which is connected to the first moving block 30, and the output shaft of the seventh driving member 32 is arranged parallel to the output shaft of the sixth driving member 29; and a second moving block 33, which is connected to the output end of the seventh driving member 32 and is movably disposed on the first moving block 30, and the second moving block 3 ... is provided with a first through hole 31 movably disposed above the working position 4; a sixth driving member 33, which is connected to the output end of the seventh driving member 32 and is movably disposed on the first moving block 30; and a sixth moving block 33 is provided with a first through hole 31 movably disposed above the working position 4; a sixth driving member 33, which is connected to the first moving block 30, and the sixth moving block The second perforation 34; the receiving sleeve 35, which is connected to the first moving block 30, has an inlet and an outlet that are arranged opposite to each other. The inlet is connected to the first vibrating plate 28 through a pipe, and the outlet is movably aligned with the second perforation 34. The receiving sleeve 35 is used to introduce the spring on the first vibrating plate 28 into the second perforation 34; the eighth driving member 36, which is connected to the first moving block 30, has a first pressing post 37 connected to its output end. The first pressing post 37 is arranged collinearly with the axis of the first perforation 31 and is used to press out the spring in the second perforation 34 when the axes of the first perforation 31 and the second perforation 34 are collinear.

[0080] The first vibratory feeder 28 contains springs to be assembled. During operation, the first vibratory feeder 28 transports the springs into the receiving sleeve 35. After passing through the inlet of the receiving sleeve 35, the springs enter the second through hole 34 on the second moving block 33 from the outlet. At this time, the sixth driving member 29 drives the first moving block 30 to move towards the working position 4 on the side of the spring feeding unit 11, so that the first through hole 31 on the first moving block 30 moves to the top of the housing 1. Then, the seventh driving member 32 drives the second moving block 33 to move, so that the first through hole 31 on the first moving block 30 moves to the top of the housing 1. The second through hole 34 on the second moving block 33 is collinear with the axis of the first through hole 31. The spring located in the second through hole 34 will fall into the housing 1 after passing through the first through hole 31 under its own weight. When the second moving block 33 moves the spring, causing the spring to tilt in the second through hole 34 and unable to pass through the first through hole 31, the eighth driving member 36 drives the first pressing column 37 to move, so that the first pressing column 37 passes through the second through hole 34 and the first through hole 31 in sequence, pressing the tilted spring into the housing 1.

[0081] More specifically, the cap feeding unit 12 of this solution includes: a second vibratory feeder 38, which is disposed on the side of the workbench 3; a second fixed frame 39, which is connected to the workbench 3; a first feeding channel 40, which is disposed on the second fixed frame 39 and connected to the second vibratory feeder 38, and the caps 2 fed by the second vibratory feeder 38 are arranged on the first feeding channel 40; a ninth driving member 41, which is horizontally disposed above the workbench 3; a tenth driving member 42, which is connected to the output end of the ninth driving member 41 and is vertically disposed; and an adsorption member 43, which is connected to the output end of the tenth driving member 42 and is movably disposed above the first feeding channel 40, and the adsorption member 43 is used to remove the caps 2 on the first feeding channel 40 and press them into the housing 1 on the working position 4.

[0082] The second vibrating plate 38 contains the cap 2 to be assembled. The first feeding channel 40 is used to connect the second vibrating plate 38. When the adsorption member 43 is connected to the air source, it is used to transport the cap 2. After the spring is installed in the housing 1, the conveying unit 14 transports the housing 1 to the working position 4 on the side of the cap feeding unit 12. At this time, the ninth driving member 41 and the tenth driving member 42 drive the adsorption member 43 to move, transport the cap 2 in the first feeding channel 40 and press it onto the housing 1, thereby completing the assembly operation of the cap 2.

[0083] In addition, the detection unit 13 includes: a third fixed frame 44, which is connected to the worktable 3; an eleventh driving member 45, which is erected on the third fixed frame 44; a pressure sensor 46, which is connected to the output end of the eleventh driving member 45; and a second pressing column 47, which is connected to the end of the pressure sensor 46 away from the eleventh driving member 45. The second pressing column 47 is used to press the assembled workpiece placed on the work position 4.

[0084] After the cap 2 is assembled, the transport unit 14 moves the assembled workpiece to the working position 4 on the side of the detection unit 13. At this time, the eleventh drive unit 45 drives the pressure sensor 46 and the second pressing column 47 to move towards the workpiece, and makes the second pressing column 47 press on the workpiece. The pressure sensor 46 feeds back the reaction force of the workpiece on the second pressing column 47 to determine whether the workpiece is qualified.

[0085] In this scheme, the conveying unit 14 includes: a fourth fixed frame 48, which is connected to the worktable 3; a twelfth drive member 49, which is vertically mounted on the fourth fixed frame 48; a first movable seat 50, which is movably connected to the fourth fixed frame 48 and connected to the output end of the twelfth drive member 49; a thirteenth drive member 51, which is horizontally connected to the first movable seat 50; a second movable seat 52, which is movably connected to the first movable seat 50 and connected to the output end of the thirteenth drive member 51; a fourteenth drive member 53, which is horizontally connected to the second movable seat 52 and vertically mounted to the thirteenth drive member 51; and a third movable seat 54, which is movably mounted on the second movable seat 52 and connected to the output end of the fourteenth drive member 53. Multiple pneumatic grippers 55 are linearly arranged on the third movable seat 54.

[0086] During operation, the fourteenth drive unit 53 first moves the third moving seat 54 toward the working position 4, causing the pneumatic gripper 55 on the third moving seat 54 to move to the outside of the housing 1 on the working position 4. Then, the pneumatic gripper 55 clamps onto the outer wall of the housing 1. Then, the twelfth drive unit 49 moves the first moving seat 50 upward, causing the pneumatic gripper 55 to rise, so that the semi-finished and finished products on the working position 4 leave the working position 4. Then, the thirteenth drive unit 51 and the fourteenth drive unit 53 work together to move the semi-finished or finished workpiece on the pneumatic gripper 55 to the top of the next adjacent working position 4. Finally, the twelfth drive unit 49 moves the first moving seat 50 downward, so that the semi-finished or finished product on the pneumatic gripper 55 is placed on the next working position 4.

[0087] Furthermore, this solution also includes a sorting unit 56, which is set on the workbench 3 and located to the side of the detection unit 13. The sorting unit 56 is used to sort qualified and unqualified workpieces. The sorting unit 56 has two discharge channels 57, one end of which is connected to form a feed channel 58. A rotating block 59 is provided in the feed channel 58. The sorting unit 56 is provided with a fifteenth driving member 60, one end of which is inserted into the feed channel 58 and connected to the rotating block 59. The fifteenth driving member 60 is used to drive the rotating block 59 to rotate, so that the feed channel 58 is connected to one of the discharge channels 57.

[0088] After the assembled workpiece is inspected by the inspection unit 13, the pneumatic gripper 55 on the conveying unit 14 clamps the workpiece into the feed channel 58. At this time, the fifteenth driving component 60 drives the rotating block 59 to block one of the feed channels 58 and the discharge channel 57 according to the inspection result of the inspection unit 13, so that qualified and unqualified workpieces can enter different discharge channels 57, and finally complete the sorting operation of the workpieces.

[0089] Furthermore, the housing feeding unit 5 includes: a third vibratory plate 61, which is disposed on the side of the workbench 3; and a second feeding channel 62, which is disposed on the workbench 3 and connected to the third vibratory plate 61 and the positioning seat 6. The second feeding channel 62 is used to introduce the housing 1 in the third vibratory plate 61 into the positioning seat 6.

[0090] The third vibratory plate 61 contains the housing 1 to be assembled. The second feeding channel 62 is used to receive the housing 1 sent out by the third vibratory plate 61 and guide it into the positioning seat 6 so that the pneumatic gripper 55 on the conveying unit 14 can correctly grasp the housing 1.
