Detailed implementation manners

[0017] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0018] It can be understood that the terms "first", "second", etc. used in the present application may be used herein to describe various elements, but unless otherwise specified, these elements are not limited by these terms. These terms are only used to distinguish one element from another.

[0019] As Figure 1 , Figure 2 , Figure 5 and Figure 8 shown, in one embodiment, a conveying and flipping device for linear guide rail processing is proposed, and the device includes: Main body frame 1: including a mounting table 101 provided on the main body frame 1, and a photoelectric sensor is arranged on the mounting table 101, and the photoelectric sensor is connected to the input end of the controller; Flipping mechanism 2: It includes a plurality of support rods 201 installed on the mounting table 101 for supporting the to-be-processed guide rail 205. A plurality of support universal balls 202 are rotatably installed on the surface of each support rod 201. It also includes a plurality of pressing rods 203 for restricting the downward movement of the to-be-processed guide rail 205. A plurality of pressing universal balls 204 are rotatably installed on the surface of each pressing rod 203. The support universal balls 202 and the pressing universal balls 204 are respectively in contact with the upper and lower surfaces of the to-be-processed guide rail 205. The pressing rod 203 is slidably connected to the inner wall of the support rod 201; Limiting mechanism 3: It is used for limiting and supporting the pressing rod 203 during its revolution; Pressing mechanism 4: It drives the pressing rod 203 to limit the to-be-processed guide rail 205 by cooperating with the special-shaped mechanism 5; Driving mechanism 6: It is used for driving the support rod 201 to revolve; Feeding mechanism 7: It is used for feeding the to-be-processed guide rail 205; Discharging mechanism 8: It is used for discharging the to-be-processed guide rail 205.

[0020] In the actual application of the embodiment of the present invention, when the flipping operation of the to-be-processed guide rail 205 is carried out, as Figure 1 shown, at this time, the to-be-processed guide rail 205 is conveyed to the feeding mechanism 7 by an external conveying device. Since the feeding mechanism 7 itself is driven to rotate, when the to-be-processed guide rail 205 passes through the photoelectric sensor, at this time, the signal fed back by the photoelectric sensor to the controller drives the feeding mechanism 7 to start moving, driving the to-be-processed guide rail 205 to be conveyed on the feeding mechanism 7. When the end of the to-be-processed guide rail 205 passes through the photoelectric sensor, at this time, the photoelectric sensor feeds back a signal to the controller to make the feeding mechanism 7 stop running, as Figure 2 shown. At the same time, the controller drives the driving mechanism 6 to start running. The operation of the driving mechanism 6 drives the support rod 201 to revolve. Each time the driving mechanism 6 runs, it drives the support rod 201 to revolve by 90 degrees, thereby driving the to-be-processed guide rail 205 to revolve. As the support rod 201 revolves and tilts, at this time, the to-be-processed guide rail 205 approaches the position of the central axis of the rotation of the support rod 201 under the action of the support universal balls 202. At this time, the to-be-processed guide rail 205 is attached to the limiting mechanism 3, as Figure 5 and Figure 8As shown in the figure, through the combined action of the pressing mechanism 4 and the special-shaped mechanism 5, the pressing rod 203 approaches the upper surface of the to-be-processed guide rail 205, so as to automatically limit the position of the to-be-processed guide rail 205. Through the contact limit of the supporting universal ball 202 and the pressing universal ball 204 with the to-be-processed guide rail 205, on the one hand, the contact friction is reduced to avoid scratching the surface of the to-be-processed guide rail 205, and on the other hand, the degree of freedom of the to-be-processed guide rail 205 for blanking is increased through point contact, so that the to-be-processed guide rail 205 can be flexibly blanked in different directions. When the support rod 201 rotates by ninety degrees, at this time, through the action of the feeding mechanism 7, a new to-be-processed guide rail 205 is loaded on the new support rod 201. When the support rod 201 rotates close to one hundred and eighty degrees, at this time, through the action of the pressing mechanism 4 and the special-shaped mechanism 5, the to-be-processed guide rail 205 is separated from the supporting universal ball 202. When the support rod 201 rotates to one hundred and eighty degrees, due to the action of the revolution inertia, the to-be-processed guide rail 205 moves a short distance away from the rotation center axis of the support rod 201 and stops under the resistance of the discharging mechanism 8, so as to be separated from the contact with the limiting mechanism 3, avoiding large friction between the blanking and the limiting mechanism 3. Since the discharging mechanism 8 and the feeding mechanism 7 share the output end of the controller, the discharging mechanism 8 and the feeding mechanism 7 operate synchronously. While the feeding mechanism 7 is loading, the already flipped to-be-processed guide rail 205 is pushed out through the action of the discharging mechanism 8, so as to achieve automatic flipping and blanking of the to-be-processed guide rail 205 and improve the flipping efficiency. At the same time, through the revolution of the driving mechanism 6, the to-be-processed guide rail 205 is continuously loaded, flipped and blanked in a cycle, achieving automatic cyclic operation and improving the flipping efficiency.

[0021] As Figure 2 and Figure 3 shown, as a preferred embodiment of the present invention, the limiting mechanism 3 includes four connecting rods 301 fixedly installed on the surface of the support rod 201. One end of every two connecting rods 301 is connected to the limiting rod 302, and buffer sponges are installed on the surface of the limiting rod 302.

[0022] In the actual application of the embodiment of the present invention, when the driving mechanism 6 drives the support rod 201 to revolve, at this time, due to the gravity of the to-be-processed guide rail 205 itself when the support rod 201 is tilted, the to-be-processed guide rail 205 moves on the supporting universal ball 202 towards the rotation center axis of the support rod 201, and then contacts the limiting rod 302. The to-be-processed guide rail 205 is supported and positioned by the buffer sponge on the limiting rod 302, so as to achieve the purpose of automatic inclined sliding positioning.

[0023] As Figure 3 、 Figure 4 、 Figure 5 、 Figure 8 and Figure 9As shown, as another preferred embodiment of the present invention, the pressing mechanism 4 includes a T-shaped rod 401 fixedly connected to the surface of the pressing rod 203. The surface of the T-shaped rod 401 is slidably connected to the inner wall of the support rod 201. A sliding rod 402 cooperating with the special-shaped mechanism 5 is fixedly installed on the surface of the T-shaped rod 401. The sliding rod 402 penetrates through the support rod 201 and is slidably connected to the support rod 201. The pressing rod 203 is connected to the inner wall of the support rod 201 through a return spring 403. The sliding rod 402 penetrates through the driving mechanism 6 and is slidably connected to the driving mechanism 6. A ball is provided at the cooperating end of the sliding rod 402 and the special-shaped mechanism 5.

[0024] In the actual application of the embodiment of the present invention, as the support rod 201 revolves, the sliding rod 402 is driven to revolve synchronously. When the support rod 201 rotates by ninety degrees, as Figure 3 、 Figure 5 and Figure 8 shown, through the cooperation of the sliding rod 402 and the special-shaped mechanism 5, the T-shaped rod 401 is driven to move towards the center axis of rotation of the support rod 201, as Figure 9 shown, and then the pressing rod 203 is driven to move towards the surface of the to-be-processed guide rail 205, so that the pressing universal ball 204 contacts the surface of the to-be-processed guide rail 205. When the support rod 201 rotates close to one hundred and eighty degrees, at this time, the sliding rod 402 drives the pressing rod 203 to move away from the support rod 201 through the action of the special-shaped mechanism 5. Due to the gravity of the to-be-processed guide rail 205 acting on the pressing rod 203 at this time, the movement of the pressing rod 203 causes the to-be-processed guide rail 205 to be separated from the support rod 201, so that the to-be-processed guide rail 205 is separated from the connecting rod 301 when the support rod 201 rotates to one hundred and eighty degrees through the inertia of revolution, thereby reducing the friction of the to-be-processed guide rail 205 during blanking and achieving the purpose of improving the blanking stability.

[0025] As Figure 8 shown, as another preferred embodiment of the present invention, the special-shaped mechanism 5 includes a special-shaped sliding rod 501 fixedly connected to the inner wall of the mounting table 101. The surface of the special-shaped sliding rod 501 is provided with an outer ring curved surface 502, a pressing curved surface 503, an inner ring curved surface 504, a relaxation curved surface 505, a transition curved surface 506 and a return curved surface 507 that cooperate with the sliding rod 402 and are smoothly connected in sequence. The track radius of the outer ring curved surface 502 is greater than the track radius of the transition curved surface 506, and the track radius of the transition curved surface 506 is greater than the track radius of the inner ring curved surface 504.

[0026] In the actual application of the embodiment of the present invention, when the support rod 201 revolves by ninety degrees, as Figure 8As shown, at this time, the sliding rod 402 is made to approach the rotation center axis of the support rod 201 by the action of pressing down the curved surface 503, so that the pressing universal ball 204 contacts the to-be-machined guide rail 205, and limits the to-be-machined guide rail 205. When the support rod 201 rotates around its axis by nearly 180 degrees, the sliding rod 402 is made to move away from the rotation center axis of the support rod 201 by the action of the relaxation curved surface 505, so that the to-be-machined guide rail 205 disengages from the supporting universal ball 202. When the support rod 201 continues to rotate around its axis, at this time, the sliding rod 402 passes through the reset curved surface 507, driving the pressing mechanism 4 to reset, thus achieving the purpose of automatic cyclic flipping.

[0027] As Figure 2 and Figure 6 shown, as another preferred embodiment of the present invention, the driving mechanism 6 includes a driving motor 601 fixedly installed on the mounting table 101. The driving motor 601 is connected to the output end of the controller. The output end of the driving motor 601 penetrates through the mounting table 101 and is rotatably connected to the mounting table 101. A driving drum 602 is fixedly installed at the output end of the driving motor 601. A plurality of support rods 201 are fixedly installed on the surface of the driving drum 602. The sliding rod 402 penetrates through the driving drum 602 and is slidably connected to the driving drum 602.

[0028] In the actual application of the embodiment of the present invention, when the end of the to-be-machined guide rail 205 passes through the photoelectric inductor, the photoelectric inductor feeds back a signal to the controller at this time, and then drives the driving motor 601 to operate. As Figure 2 shown, the operation of the driving motor 601 drives the driving drum 602 to rotate, and then drives the support rod 201 to rotate around its axis, thus achieving the purpose of automatically driving the to-be-machined guide rail 205 to cyclically flip.

[0029] As Figure 1 shown, as another preferred embodiment of the present invention, the feeding mechanism 7 includes a feeding motor 701 fixedly installed on the mounting table 101. The feeding motor 701 is connected to the output end of the controller. The output end of the feeding motor 701 penetrates through the mounting table 101 and is rotatably connected to the mounting table 101. A rotating gear set 702 is fixedly installed at the output end of the feeding motor 701. A feeding chain 703 is sleeved on the surface of the rotating gear set 702, and the feeding chain 703 forms a chain drive with the remaining plurality of rotating gear sets 702. The shaft section of each rotating gear set 702 penetrates through the mounting table 101 and is rotatably connected to the mounting table 101. A feeding roller 704 is coaxially and fixedly installed on the surface of the shaft section of each rotating gear set 702. The plurality of feeding rollers 704 are arranged adjacent to and spaced from the support rod 201, and both the feeding roller 704 and the supporting universal ball 202 are tangent to the same horizontal plane.

[0030] In actual application of the embodiment of the present invention, when the guide rail 205 to be processed is transported to the position of the feed roller 704 by an external conveying device, the photoelectric sensor feeds back a signal to the controller, thereby driving the feed motor 701 to operate. The operation of the feed motor 701 drives the feed roller 704 to rotate through a chain drive, thereby driving the guide rail 205 to be processed to move to the support rod 201 and separate from the original external conveying equipment, thereby achieving the purpose of automatic loading.

[0031] like Figure 1 and Figure 7 As shown, as another preferred embodiment of the present invention, the discharging mechanism 8 includes a discharging motor 801 fixedly mounted on the mounting platform 101, the discharging motor 801 is connected to the output end of the controller, the output end of the discharging motor 801 passes through the mounting platform 101 and is rotatably connected to the mounting platform 101, and the output end of the discharging motor 801 is fixedly mounted with a discharging gear set 802, the surface of the discharging gear set 802 is sleeved with a discharging chain 803, and the discharging chain 803 forms a chain drive with the remaining multiple discharging gear sets 802, the shaft section of each discharging gear set 802 passes through the mounting platform 101 and is rotatably connected to the mounting platform 101, and the shaft section surface of each discharging gear set 802 is coaxially fixedly mounted with a discharging roller 804, and multiple discharging rollers 804 are arranged adjacent to the lower pressure rod 203 at intervals, and the discharging rollers 804 and the lower pressure universal ball 204 are tangent to the same horizontal plane.

[0032] In actual application of the embodiment of the present invention, after the support rod 201 rotates one hundred and eighty degrees, the top of the downward-pressing universal ball 204 is exactly on the same horizontal plane as the top of the discharge roller 804. At this time, the feeding mechanism 7 feeds the new guide rail 205 to be processed normally, and the discharge motor 801 starts to run. The operation of the discharge motor 801 drives the discharge roller 804 to rotate through chain transmission, thereby achieving the purpose of automatically unloading the guide rail 205 to be processed.
