[0002] The compressor housing is a load-bearing component of the compressor, and its loading accuracy and posture consistency directly determine the assembly accuracy and product qualification rate of subsequent processes such as end cover assembly, bearing pressing, and bolt fastening. Currently, the housing loading operation in existing compressor assembly lines has shortcomings; the angle of the housing on the conveyor belt differs from the target angle, requiring manual adjustment of the housing angle. Therefore, how to adjust the housing angle is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0003] To overcome the above-mentioned shortcomings, the purpose of this invention is to provide an automatic feeding and posture correction device for the housing of a motor compressor assembly line.

[0004] To achieve the above objectives, the technical solution adopted by this invention is as follows: an automatic feeding and posture correction device for the housing of a motor compressor assembly line, comprising a conveyor belt with housings mounted on it; a base plate is provided below the conveyor belt, with several support columns connected to the edge of the base plate, a top plate connected to the upper end of the support columns, an electric push rod installed in the middle of the top plate, the electric push rod having a movable rod, and a CCD camera installed at the lower end of the movable rod; a transfer plate is provided in the middle of the movable rod, and the movable rod and the transfer plate are rotatably connected by a first bearing; a pair of rotating seats and a motor seat are fixedly installed on the transfer plate, a worm gear is rotatably connected between the pair of rotating seats, a motor is provided in the motor seat, and the motor drives the worm gear to rotate; a worm wheel is connected to the movable rod, and the worm wheel meshes with the worm gear;

[0005] The transfer plate has several mounting slots along its edge, and clamping rods are installed in the mounting slots. The clamping rods are rotatably connected to a pair of slot walls by a first hinge pin. A cylinder is connected to the top of the clamping rod. One end of the cylinder is connected to the clamping rod by a fourth hinge pin, and the other end of the cylinder is connected to the transfer plate by a hinge seat. A slip ring is slidably connected to the movable rod. A first connecting rod is connected between the slip ring and the middle of the clamping rod. The two ends of the first connecting rod are connected to the slip ring and the clamping rod by a third hinge pin and a second hinge pin, respectively.

[0006] A further feature of the present invention is that a limit ring is connected to the lower end of the movable rod.

[0007] A further feature of the present invention is that a second bearing is provided between the slip ring and the movable rod.

[0008] The invention is further configured such that: a mounting plate is provided on the base plate, and the base plate and the mounting plate are connected by a bolt and nut assembly; a plurality of long grooves are provided in the base plate, and the bolt and nut assembly passes through the long grooves; a pair of "L"-shaped brackets are connected to the mounting plate, and a guide plate is connected to the top of the pair of brackets, with the middle part of the guide plate protruding toward the center line of the conveyor belt.

[0009] The present invention is further configured such that: the guide plate includes a first guide surface, a second guide surface, a third guide surface, a mounting ring, and a fourth guide surface; the angle between the first guide surface and the second guide surface, and the angle between the second guide surface and the third guide surface are the same, both being obtuse angles; a mounting ring is connected to both the first guide surface and the third guide surface; the fourth guide surface is connected to the upper edge of the second guide surface, and the upper edge of the fourth guide surface bends outward and extends.

[0010] A further feature of the present invention is that a gasket is provided at the lower end of the clamping rod.

[0011] The present invention is further configured such that: a fifth hinge pin is provided in the middle of the first connecting rod, a second connecting rod is rotatably connected to the fifth hinge pin, a sixth hinge pin is provided at the end of the second connecting rod, a protective ring is rotatably connected to the sixth hinge pin, and a lens is provided in the protective ring.

[0012] Compared with existing technologies, the beneficial effects of this invention are as follows: A conveyor belt loads the machine housing. A CCD camera takes pictures of the machine housing to detect its angle. The required rotation angle is calculated by comparing it with a preset target angle. An electric push rod is activated, driving the movable rod downwards until the upper end of the machine housing is between the lower ends of several clamping rods. A cylinder is activated, driving the clamping rods to rotate around the first hinge pin. Since the clamping rods and slip rings are connected by a first connecting rod, the remaining first connecting rods and clamping rods rotate synchronously, and the clamping rods together clamp the upper part of the machine housing. Then, the motor is activated, and the worm gear meshes with the worm wheel. Since the worm wheel is fixedly connected to the movable rod and cannot rotate, the rotating seat, motor, and transfer plate rotate until the angle of the machine housing is at the target angle. Afterwards, the cylinder resets, pulling the clamping rods open, and the clamping rods disengage from the machine housing. The transfer plate and movable rod reset. Then, the conveyor belt transports the machine housing to the next workstation. Attached Figure Description

[0019] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more explicit definition of the scope of protection of the present invention.

[0020] See Figure 1-5 As shown in this embodiment, an automatic feeding and posture correction device for the housing of a motor compressor assembly line includes a conveyor belt 1, on which a housing 8 is mounted; a base plate 2 is provided below the conveyor belt 1, and several support columns 9 are connected to the edge of the base plate 2. A top plate 10 is connected to the upper end of the support columns 9, and an electric push rod 11 is installed in the middle of the top plate 10. The electric push rod 11 has a movable rod 33, and a CCD camera 21 is installed at the lower end of the movable rod 33; a transfer plate 13 is provided in the middle of the movable rod 33, and the movable rod 33 and the transfer plate 13 are rotatably connected by a first bearing 12; a pair of rotating seats 23 and a motor seat 25 are fixedly mounted on the transfer plate 13, and a worm gear 14 is rotatably connected between the pair of rotating seats 23. A motor 24 is provided in the motor seat 25, and the motor 24 drives the worm gear 14 to rotate; a worm wheel 15 is connected to the movable rod 33, and the worm wheel 15 is meshed with the worm gear 14.

[0021] The edge of the transfer plate 13 is provided with several mounting grooves 16, and a clamping rod 18 is provided in the mounting groove 16. The clamping rod 18 is rotatably connected to a pair of groove walls of the mounting groove 16 by a first hinge pin 17. A cylinder 30 is connected to the top of the clamping rod 18. One end of the cylinder 30 is connected to the clamping rod 18 by a fourth hinge pin 32, and the other end of the cylinder 30 is connected to the transfer plate 13 by a hinge seat 31. A slip ring 27 is slidably connected to the movable rod 33. A first connecting rod 26 is connected between the slip ring 27 and the middle of the clamping rod 18. The two ends of the first connecting rod 26 are connected to the slip ring 27 and the clamping rod 18 by a third hinge pin 29 and a second hinge pin 19, respectively.

[0022] Conveyor belt 1 loads housing 8. CCD camera 21 takes pictures of housing 8 to detect its angle. The required rotation angle is calculated by comparing it with a preset target angle. Electric push rod 11 is activated, driving movable rod 33 to move downwards until the upper end of housing 8 is between the lower ends of several clamping rods 18. Cylinder 30 is activated, driving clamping rods 18 to rotate around the first hinge pin 17. Since clamping rods 18 and slip ring 27 are connected by a first connecting rod 26, the remaining first connecting rods 26 and clamping rods 18 rotate synchronously, and several clamping rods 18 together clamp the upper part of housing 8. Then, motor 24 is activated, worm gear 14 meshes with worm wheel 15. Since worm wheel 15 is fixedly connected to movable rod 33 and cannot rotate, rotating seat 23, motor 24, and intermediate plate 13 rotate until the angle of housing 8 is at the target angle. Then, cylinder 30 resets, pulling clamping rods 18 open, disengaging clamping rods 18 from housing 8. Intermediate plate 13 and movable rod 33 reset. Then, the conveyor belt 1 transports the housing 8 to the next station. Preferably, the height of the CCD camera 21 is higher than the height of the second hinge pin 19, so that when the movable rod 33 descends, the middle part of the first connecting rod 26 contacts the top of the housing 8, thus preventing the CCD camera 21 from colliding with and being damaged by the housing 8.

[0023] The lower end of the movable rod 33 is connected to a limiting ring 22. A second bearing 28 is provided between the slip ring 27 and the movable rod 33. Preferably, the second bearing 28 is a linear bearing, and the first bearing 12 is a bearing capable of bearing axial and radial forces, such as a thrust radial roller bearing. A mounting plate 4 is provided on the base plate 2, and the base plate 2 and the mounting plate 4 are connected by a bolt and nut assembly 5; the base plate 2 is provided with several long grooves 3, and the bolt and nut assembly 5 passes through the long grooves 3; a pair of "L"-shaped brackets 6 are connected to the mounting plate 4, and a guide plate 7 is connected to the top of the pair of brackets 6. The middle part of the guide plate 7 protrudes towards the center line of the conveyor belt 1. Guide plates 7 are provided on both sides of the upper surface of the conveyor belt 1. The housing 8 contacts the first guide surface 71, and the first guide surface 71 guides the housing 8 to move towards the center line of the conveyor belt 1 until it is between a pair of second guide surfaces 72. The guide plate 7 includes a first guide surface 71, a second guide surface 72, a third guide surface 73, a mounting ring 74, and a fourth guide surface 75. The included angle A between the first guide surface 71 and the second guide surface 72, and the included angle B between the second guide surface 72 and the third guide surface 73, are both obtuse angles. Mounting rings 74 are connected to both the first guide surface 71 and the third guide surface 73. The fourth guide surface 75 is connected to the upper edge of the second guide surface 72, and the upper edge of the fourth guide surface 75 bends outward. Preferably, the guide plate 7 contacts the lower part of the housing 8 but not the upper part. If necessary, the housing 8 can be clamped by the clamping rod 18 and raised by the movable rod 33, causing the housing 8 to detach from the conveyor belt 1 and the guide plate 7. The motor 24 drives the housing 8 to perform horizontal rotation inspection via the worm gear 14 and the worm wheel 15. After inspection, the movable rod 33 descends, and the fourth guide surface 75 guides the lower end of the housing 8 into the space between the pair of second guide surfaces 72. Preferably, the guide plate 7 is made of spring steel. A gasket 20 is provided at the lower end of the clamping rod 18.

[0024] Preferably, a fifth hinge pin 35 is provided at the middle of the first connecting rod 26, and a second connecting rod 34 is rotatably connected to the fifth hinge pin 35. A sixth hinge pin 36 is provided at the end of the second connecting rod 34, and a protective ring 37 is rotatably connected to the sixth hinge pin 36. A lens 38 is provided in the protective ring 37. The protective ring 37 is located between the CCD camera 21 and the housing 8, protecting the CCD camera 21 and preventing it from being damaged by collision with the housing 8. The lens 38 reduces the size of the image of the housing 8 (which is relatively large) and transmits it to the CCD camera 21, thus expanding the viewing angle of the CCD camera 21 and making the viewing angle wider.
