Description

Technical Field

[0001] This invention relates to the field of motor parts manufacturing technology, and in particular to an automatic stamping production line for balance plates. Background Technology

[0002] The motor balance plate is made of ring-shaped aluminum plate material. Most existing balance plates are processed by cutting aluminum rods.

[0003] The inventors discovered that existing materials produced by cutting aluminum rods have a large processing area, are difficult to control in terms of thickness, require secondary manual processing of the surface, are difficult to integrate with the production line, and have low production efficiency. At the same time, the screening of products and waste materials requires manual picking or the use of vibrating screens. Manual picking is inefficient and labor-intensive, while vibrating screens can easily damage the products. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide an automatic stamping production line for balance plates. This line uses sheet metal for stamping to produce balance plates, which reduces production difficulty while ensuring product quality. Simultaneously, it utilizes a material discharge chute for automatic screening of finished products and waste materials, eliminating vibration and effectively preventing damage to finished products. This solves the problems of low production efficiency and poor product quality in existing motor-driven balance plate production lines.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution:

[0006] In a first aspect, the present invention provides an automatic stamping production line for balance plates, including a feeding mechanism, a conveying mechanism, a stamping mechanism, and a sorting mechanism. The conveying mechanism is used to transport aluminum plates stored in the feeding mechanism to the stamping mechanism for stamping and forming. The sorting mechanism is provided with a downwardly inclined sorting plate, which is connected to the stamping mechanism via a conveyor belt to receive balance plates and scrap. A discharge chute penetrating the sorting plate is provided on the sorting plate. The discharge chute is divided into a long strip chute and a circular chute. The long strip chute is close to the conveyor belt and its width is smaller than that of the balance plate. The diameter of the circular chute is equal to the outer diameter of the balance plate. A guide blocking unit is provided on the periphery of the discharge chute.

[0007] As a further implementation, the feeding mechanism consists of a lifting frame and a first robotic arm fixedly mounted on the top of the lifting machine. The first robotic arm consists of a push plate and a telescopic cylinder that drives the push plate to move, so as to push the aluminum plate onto the feeding mechanism.

[0008] As a further implementation, the feeding mechanism consists of a support frame and a first conveyor belt mounted on the support frame. A number of support plates and support platforms are spaced apart along the length of one side of the support frame. The end of the support plate near the feeding mechanism is inclined downward, and a number of rollers are rotatably mounted on the support platform along its length.

[0009] As a further implementation, the stamping mechanism consists of an operating table, a second robotic arm mounted on the operating table, a die base, and a second conveyor belt. A stamping unit is provided above the die base. The second conveyor belt and the second robotic arm are arranged opposite each other on both sides of the die base. First guide plates are provided on both sides of the second conveyor belt. An outwardly inclined first baffle is fixedly provided at one end of the first guide plate near the die base.

[0010] As a further implementation, the stamping mechanism is also provided with a punch for stamping the inner hole. The punch is divided into upper and lower sections, with the diameter of the lower section being smaller than that of the upper section.

[0011] As a further implementation, the stamping mechanism is connected to the third conveyor belt on the sorting mechanism via an inclined connecting plate. Two second guide plates are provided on the end of the third conveyor belt away from the connecting plate. The discharge ends of the two guide plates are close to each other and adjacent to the sorting plate, while the feed ends are far apart from each other.

[0012] As a further implementation, the guide blocking unit is fixedly installed on the material distribution plate. The guide blocking unit consists of a third guide plate and a second baffle. The two third guide plates are arranged opposite each other on both sides of the material discharge chute. The second baffle is located between the two third guide plates and perpendicular to the third guide plates. The second baffle is located at the end of the third guide plate away from the second guide plate to block the sliding balance plate at the circular groove.

[0013] As a further implementation, the distance between the two third guide plates is equal to the outer diameter of the balance plate.

[0014] As a further implementation, a fourth conveyor belt is provided below the elongated trough, with one end of the fourth conveyor belt connected to the waste bin.

[0015] As a further implementation, a receiving rack is provided below the circular groove. The receiving rack consists of a turntable and several vertically fixed columns on the turntable. The columns are spaced apart along the circumference of the turntable, and the turntable is driven by a servo motor.

[0016] The beneficial effects of the present invention are as follows:

[0017] (1) The present invention uses sheet metal to stamp and produce balance plates, which reduces the production difficulty while ensuring product quality. At the same time, the material chute is used to automatically screen finished products and waste materials without vibration, which effectively avoids damage to finished products.

[0018] (2) The end of the support plate near the feeding mechanism of the present invention is inclined downward, which makes it easier to push the aluminum plate onto the support plate. Several rollers are provided on the support platform along its length direction to reduce the friction between the aluminum plate and the support platform and avoid friction damage to the aluminum plate during the process of pushing it onto the first conveyor belt.

[0019] (3) The punch of the present invention is divided into two sections, the lower section having a smaller diameter than the upper section, which allows for secondary punching of the inner hole of the circular aluminum plate to ensure that the inner hole is 100% bright in size and appearance, without producing burrs, bending or other phenomena, thus greatly ensuring the quality of the product.

[0031] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the invention. Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0032] As described in the background section, existing materials produced by cutting aluminum rods have a large processing area, difficult thickness control, and require secondary manual processing of the surface. They are difficult to integrate with the production line, resulting in low production efficiency. In addition, the screening of products and waste materials requires manual picking or the use of vibrating screens. Manual picking is inefficient and labor-intensive, while vibrating screens can easily damage the products. To solve the above technical problems, this invention proposes an automatic stamping production line for balance plates.

[0033] Example 1

[0034] In a typical embodiment of the present invention, such as Figures 1-5 As shown, an automatic stamping production line for balance plates is proposed, including a feeding mechanism 1, a feeding mechanism 2, a stamping mechanism 3, and a sorting mechanism 4 connected in sequence.

[0035] The feeding mechanism 1 is mainly used for storing aluminum plates and placing them on the feeding mechanism 2, such as... Figure 2 As shown, the feeding mechanism 1 consists of a lifting frame 11 and a first robot arm 12. There are at least two lifting frames 11. The lifting frames 11 are placed on one side of the feeding mechanism 2. Several lifting frames 11 are on the same horizontal line. A first robot arm 12 is fixed on the top of each lifting frame 11.

[0036] The lifting frame 11 is equipped with a lifting handle for supporting the aluminum plate. The lifting handle is slidably mounted on the lifting frame 11 and driven by a motor. The lifting handle can move vertically along the lifting frame 11.

[0037] The first robotic arm 12 consists of a telescopic cylinder and a push plate fixedly installed at the end of the telescopic cylinder's telescopic rod. The height of the first robotic arm 12 is the same as the height of the feeding mechanism 2. The push plate can push the aluminum plate onto the conveyor belt of the feeding mechanism 2.

[0038] like Figure 3 As shown, the feeding mechanism 2 consists of a bracket 21, a first conveyor belt 22, a support plate 23, and a support platform 24. The first conveyor belt 22 is mounted on the bracket 21 and is arranged along the length of the bracket 21. The first conveyor belt 22 is driven by a servo motor fixedly mounted on the bracket 21 to transport the aluminum plate to the stamping mechanism 3.

[0039] Multiple support plates 23 and support platforms 24 are provided. Both support plates 23 and support platforms 24 are fixedly mounted on the bracket 21 by welding. Specifically, support plates 23 are fixedly mounted on the side of the bracket 21 near the feeding mechanism 1 and are spaced apart along the length of the bracket 21. The end of the support plate 23 near the feeding mechanism 1 is inclined downward so that the aluminum plate can be pushed onto the support plate 23.

[0040] The support platform 24 is also fixedly installed on the side of the bracket 21 near the feeding mechanism 1 and spaced apart along the length of the bracket 21. The height of the support platform 24 is the same as the height of the support plate 23. Several rollers are rotatably provided on the support platform 24 along its length to reduce the friction between the aluminum plate and the support platform 24 and avoid friction damage to the aluminum plate during the process of pushing it to the first conveyor belt 22.

[0041] The support 21 is also equipped with a sensor to detect whether there is material on the first conveyor belt 22. The sensor is located at one end of the support 21 near the stamping mechanism 3. When no material is detected, it can send a signal to the control system. After receiving the signal, the control system controls the feeding mechanism 1 to push the aluminum plate onto the first conveyor belt 22.

[0042] Understandably, the feeding mechanism 2 is also equipped with an emergency unit. When the stamping process is temporarily or unexpectedly stopped, the feeding operation can be stopped and the system can resume normal operation after the stamping process is restored. This emergency unit is existing technology, and we will not go into too much detail here.

[0043] like Figure 4 As shown, the stamping mechanism 3 consists of an operating table, a second robotic arm 31, a die base 32, a stamping unit 33, a punch 34, a second conveyor belt 35, and a connecting plate 38. The second robotic arm 31, the die base 32, the stamping unit 33, the punch 34, the second conveyor belt 35, and the connecting plate 38 are all mounted on the operating table.

[0044] The mold base 32 is used to place the mold mother plate, and the stamping unit 33 is located above the mold base 32. The stamping unit 33 can work in conjunction with the mold mother plate and is mainly used for stamping and forming of round aluminum plate products.

[0045] The second robotic arm 31 is fixedly mounted on one side of the mold base 32. The second robotic arm 31 consists of a telescopic cylinder and a push plate fixedly mounted on the end of the telescopic cylinder's telescopic rod. The second robotic arm 31 is in the same plane as the mold mother plate and can push the round aluminum plate product out of the mold base 32 through the push plate.

[0046] An air gun is also installed on the control panel near the second robotic arm 31 to blow out the waste powder and prevent the waste powder from affecting the subsequent stamping of aluminum plates.

[0047] Punch 34 is mounted on stamping unit 33 and is used to punch holes in the middle of the finished circular aluminum plate. Punch 34 has a variable diameter structure and is divided into upper and lower sections. The diameter of the lower section is smaller than that of the upper section, which allows for secondary punching of the inner hole of the circular aluminum plate to ensure that the inner hole is 100% bright in size and appearance, without producing burrs, bending or other defects, thus greatly ensuring the quality of the product.

[0048] It should be noted that the pushing speed of the second robotic arm 31 should be the same as the punching speed of the stamping machine to avoid the mold damaging the second robotic arm 31.

[0049] The second conveyor belt 35 is located on one side of the mold base 32 and is opposite to the second robot arm 31. The second robot arm 31 can push the finished products and waste materials on the mold base 32 onto the second conveyor belt 35, so that they can be transported to the sorting mechanism 4 by the second conveyor belt 35.

[0050] A first guide plate 37 is provided on each side of the second conveyor belt 35. The first guide plate 37 is arranged along the length of the second conveyor belt 35 and is fixedly installed on the operating table. It is mainly used to guide the material on the second conveyor belt 35 and prevent the material from sliding out of the second conveyor belt 35 during the conveying process.

[0051] Each first guide plate 37 is fixed with a first baffle 36 at one end near the mold base 32. The first baffle 36 is inclined outward relative to the first guide plate 37, thereby blocking the waste and finished products on the mold base 32. When the second robot arm 31 pushes, the waste and finished products can be effectively pushed onto the second conveyor belt 35 by the action of the two first baffles 36 without falling outward.

[0052] The connecting plate 38 is located at the end of the second conveyor belt 35 away from the mold base 32. The connecting plate 38 is inclined and the two sides of the connecting plate 38 are fixed with baffles to prevent the material from sliding outward. The material on the second conveyor belt 35 can slide down onto the conveyor belt of the sorting mechanism 4 under the action of the connecting plate 38.

[0053] Specifically, one end of the connecting plate 38 is hinged to the operating table, and the other end is placed above the conveyor belt of the sorting mechanism 4. The bottom of the connecting plate 38 is supported by the support frame on the sorting mechanism 4.

[0054] like Figure 4 As shown, the sorting mechanism 4 is equipped with a third conveyor belt 41, which is connected to the connecting plate 38. Materials sliding off the connecting plate 38 can be loaded onto the third conveyor belt 41 and then transported by the third conveyor belt 41.

[0055] A second guide plate 42 is provided on the end of the third conveyor belt 41 away from the connecting plate 38 for guiding finished products and waste materials. There are two second guide plates 42, and both second guide plates 42 are fixedly installed on the mounting platform for installing the third conveyor belt 41. One end of the two second guide plates 42 is close to each other, and the other end is far away from each other. It can also be understood that the discharge end of the two guide plates 42 is close to each other, and the feed end is far away from each other. The end that is close to each other is adjacent to the sorting unit so that finished products and waste materials can accurately enter the sorting unit.

[0056] The sorting unit is equipped with a mounting frame, on which a sorting plate 43 is fixed. The sorting plate 43 is inclined downwards, and the finished products and waste materials on the third conveyor belt 41 slide into the sorting plate 43 and can slide downwards along the sorting plate 43.

[0057] The material distribution plate 43 is fixedly provided with a guide blocking unit. Specifically, the guide blocking unit consists of a third guide plate 44 and a second baffle 45. The two third guide plates 44 are arranged opposite to each other and are parallel to each other. The distance between the two third guide plates 44 is equal to the distance between the two ends of the two second guide plates 42 that are close to each other, and both are equal to the outer diameter of the annular finished product.

[0058] Understandably, the distance between the two third guide plates 44 can also be slightly larger than the outer diameter of the balance plate, but it should not be too large, so as to ensure that the balance plate can slide accurately into the circular groove. The specific dimensions can be determined according to actual needs.

[0059] One end of the third guide plate 44 is close to the discharge end of the second guide plate 42, and several annular finished products can enter the space between the two third guide plates 44 in sequence and accurately under the action of the two second guide plates 42.

[0060] The second baffle 45 is fixedly disposed between the two third guide plates 44 and perpendicular to the third guide plates 44. The second baffle 45 is located at the end of the third guide plate 44 away from the second guide plate 42, so as to block the annular finished product and prevent the annular finished product from sliding down the material distribution plate 43 to the ground.

[0061] The material distribution plate 43 is provided with a material drop trough 46 that runs through the material distribution plate 43. The material drop trough 46 is located inside the guide blocking unit and between two third guide plates 44. The material drop trough 46 is divided into two parts. One part is a long strip trough. The width of the long strip trough is smaller than the outer diameter of the annular finished product (i.e., the balance plate). Thus, the balance plate can slide between the third guide plates 44 without falling out of the long strip trough, while the waste material can fall down through the long strip trough.

[0062] A fourth conveyor belt 47 is provided below the elongated trough. One end of the fourth conveyor belt 47 is connected to the waste bin 48. Waste falling from the elongated trough can fall onto the fourth conveyor belt 47 and be transported to the waste bin 48 via the fourth conveyor belt 47.

[0063] The other part of the material drop chute 46 is a circular chute, which is located between the two third guide plates 44 and close to the second baffle 45. The diameter of the circular chute is the same as the outer diameter of the balance plate, and the balance plate can fall downward through the circular chute.

[0064] A receiving rack 49 is provided directly below the circular trough for collecting the balance plate. The receiving rack 49 consists of a turntable 491 and columns 492. Several columns 492 are provided and vertically fixed on the upper surface of the turntable 491. The columns 492 are spaced apart along the circumference of the turntable 491. The turntable 491 can rotate around the axis under the drive of a servo motor.

[0065] When collecting the balance plate, the turntable 491 can rotate under the drive of the servo motor, so that a column 492 on the turntable 491 is located directly below the circular groove. The balance plate can fall down through the circular groove, and the column 492 passes through the inner hole in the middle of the balance plate to collect the balance plate.

[0066] Because the balance plate is produced by stamping sheet metal, the stamping process does not change the thickness of the sheet metal, which allows for better control of the thickness of the balance plate. Moreover, the stamping process provides a better cutting effect on the balance plate, and the product dimensions can be precisely controlled by the stamping die. Furthermore, stamping sheet metal makes it easier to position the sheet metal without causing stamping deviations.

[0067] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
