[0051] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0052] See also Figures 1 to 3 , Figure 1 A schematic diagram of the structure of a plate-type parts conveying device provided in an embodiment of the present invention, Figure 2 A front view of a plate-like parts conveying device provided in an embodiment of the present invention, Figure 3 A top view of a plate parts conveying device provided in an embodiment of the present invention.

[0053] Disclosed in an embodiment of the present invention is a plate-like parts conveying device, which is used to convey plate-like parts between a first station, a second station and a third station arranged in sequence, wherein the first station, the second station and the third station respectively perform different processes.

[0054] The plate-type parts conveying device includes a positioning and moving assembly 100 , a driving assembly 200 and a clamping and fixing assembly 300 .

[0055] Among them, the positioning and moving component 100 includes a moving base 110, a lifting mechanism 120 and a positioning mechanism 130. The lifting mechanism 120 is arranged on the moving base 110, and the positioning mechanism 130 is arranged at the lifting end of the lifting mechanism 120. The positioning mechanism 130 is used to position and cooperate with the plate parts. When the lifting mechanism 120 rises to a preset height, the positioning mechanism 130 positions and cooperates with the plate parts and makes the plate parts detach from the clamping and fixing component 300. When the lifting mechanism 120 descends to a preset height, the positioning mechanism 130 places the plate parts in the clamping and fixing component 300 and then detaches from the plate parts.

[0056] The driving assembly 200 is transmission-connected to the movable base 110 to drive the movable base 110 to reciprocate between the first station, the second station and the third station.

[0057] The clamping and fixing assembly 300 is disposed at the first station and the second station, and is used to clamp and fix the plate parts so that the plate parts are separated from the positioning mechanism 130 when the lifting mechanism 120 descends, and to maintain the stability of the plate parts during the processing.

[0058] During application, after the plate-like part is processed at the first station, the clamping and fixing assembly 300 releases the plate-like part. The moving base 110 moves below the plate-like part, and the lifting mechanism 120 jacks up the positioning mechanism 130 to make the positioning mechanism 130 be in positioning cooperation with the plate-like part. The driving assembly 200 drives the moving base 110 to move to the second station. The lifting mechanism 120 drives the positioning mechanism 130 to descend, places the plate-like part on the clamping and fixing assembly 300 at the second station and clamps it, and then performs processing at the second station. After the process at the second station is completed, the clamping and fixing assembly 300 at the second station releases the plate-like part. The moving base 110 moves below the plate-like part, and the lifting mechanism 120 jacks up the positioning mechanism 130 to make the positioning mechanism 130 be in positioning cooperation with the plate-like part. The driving assembly 200 drives the moving base 110 to move to the third station.

[0059] Compared with the prior art, the plate-like part conveying device provided by the embodiment of the present invention can realize the conveyance of plate-like parts among multiple stations. During the transfer process, the plate-like parts are positioned by the positioning mechanism 130, and the transfer is more stable, which can avoid the problems of easy collision deformation and scratching during the hoisting of plate-like parts, improve the product quality, reduce the defect rate. At the same time, the plate-like part conveying device can be refitted on the basis of the existing production line, with small modification and low cost, and has more general applicability.

[0060] Since this case needs to transfer among three stations, in order to improve the transfer efficiency, in an embodiment of the present application, as Figures 1 to 3 shown, the moving base 110 is composed of two mutually independent movable parts, that is, the moving base 110 includes a first base 111 and a second base 112. The first base 111 is reciprocally movably arranged between the first station and the second station. After the first base 111 transports the plate-like part from the first station to the second station, the plate-like part is fixed by the clamping and fixing assembly 300 at the second station, and the first base 111 returns to the first station to facilitate the transportation of the next plate-like part to be processed. The second base 112 is reciprocally movably arranged between the second station and the third station. After the process at the second station is completed, the second base 112 loads the plate-like part from the second station and transfers it to the third station.

[0061] Since the present application is provided with two bases, namely the first base 111 and the second base 112, correspondingly, the lifting mechanism 120 includes a first lifting device 121 arranged on the first base 111 and a second lifting device 122 arranged on the second base 112. The positioning mechanism 130 includes a first positioning device 131 arranged at the lifting end of the first lifting device 121 and a second positioning device 132 arranged at the lifting end of the second lifting device 122.

[0062] As Figure 2 、 Figure 4 、Figure 5 and Figure 6 As shown in Figure 6 , in the present application, the driving assembly 200 includes a first driving device 210 for driving the first base 111. The first driving device 210 includes a moving support member 211, a driving motor 212, a first-stage transmission mechanism 213, and a second-stage transmission mechanism 214.

[0063] Among them, the moving support member 211 is reciprocally movably arranged between the first working position and the second working position. The first base 111 is slidably arranged on the moving support member 211, that is, the moving support member 211 can reciprocally slide on the device support base 400, and the first base 111 can reciprocally slide on the moving support member 211.

[0064] The driving motor 212 is arranged below the moving support member 211 through a fixing seat 500, and is used for outputting torque to drive the moving support member 211 and the first base 111 to reciprocally move between the first working position and the second working position.

[0065] The first-stage transmission mechanism 213 is used to drive the moving support member 211 to reciprocally move between the first working position and the second working position. As Figure 5 and Figure 6 shown, the first-stage transmission mechanism 213 includes a driving wheel 2131 and a first transmission belt 2132. The driving wheel 2131 is arranged at the output end of the driving motor 212. The first end of the first transmission belt 2132 is connected to the first end of the moving support member 211, and the second end of the first transmission belt 2132 bypasses the driving wheel 2131 and is connected to the second end of the moving support member 211. When the driving wheel 2131 rotates under the drive of the driving motor 212, both ends of the first transmission belt 2132 reciprocally move along with the rotation of the driving wheel 2131, thereby driving the moving support member 211 to reciprocally move.

[0066] The second-stage transmission mechanism 214 is used to move along with the moving support member 211 and drive the first base 111 to reciprocally move between the first working position and the second working position. As Figure 5 and Figure 6 shown, the second-stage transmission mechanism 214 includes a first transmission wheel 2141, a second transmission wheel 2142, a third transmission wheel 2143, a fourth transmission wheel 2144, a second transmission belt 2145, and a third transmission belt 2146. The first transmission wheel 2141 is rotatably arranged at the first end of the moving support member 211. The second transmission wheel 2142 is rotatably arranged at the second end of the moving support member 211. The third transmission wheel 2143 is rotatably arranged on the side of the first base 111 close to the first transmission wheel 2141. The fourth transmission wheel 2144 is rotatably arranged on the side of the first base 111 close to the second transmission wheel 2142.

[0067] The first end of the second transmission belt 2145 is fixed to the fixed seat 500. The second end of the second transmission belt 2145 sequentially bypasses the first transmission wheel 2141 and the third transmission wheel 2143 and then is fixed to the movable support member 211. The first end of the third transmission belt 2146 is fixed to the fixed seat 500. The second end of the third transmission belt 2146 sequentially bypasses the second transmission wheel 2142 and the fourth transmission wheel 2144 and then is fixed to the movable support member 211.

[0068] When the movable support member 211 moves towards Figure 5 and Figure 6 the left side, since the first transmission wheel 2141, the second transmission wheel 2142, and the second ends of the second transmission belt 2145 and the third transmission belt 2146 are arranged on the movable support member 211, the first transmission wheel 2141, the second transmission wheel 2142, and the second ends of the second transmission belt 2145 and the third transmission belt 2146 all move synchronously with the movable support member 211. At the same time, since the first ends of the second transmission belt 2145 and the third transmission belt 2146 are both fixed to the fixed seat 500 and cannot move, the distance between the first transmission wheel 2141 and the fixed seat 500 increases, that is, the part of the second transmission belt 2145 between the first transmission wheel 2141 and the fixed seat 500 begins to become longer. At the same time, since the total length of the second transmission belt 2145 remains unchanged, the lengths of the part of the second transmission belt 2145 between the third transmission wheel 2143 and the first transmission wheel 2141 and the part of the second transmission belt 2145 between the third transmission wheel 2143 and the movable support member 211 begin to shorten, manifested as the third transmission wheel 2143 approaching the second transmission wheel 2142.

[0069] At the same time, the distance between the second transmission wheel 2142 and the fixed seat 500 shortens, that is, the part of the third transmission belt 2146 between the second transmission wheel 2142 and the fixed seat 500 begins to shorten, and the distance between the fourth transmission wheel 2144 and the second transmission wheel 2142 begins to increase, and the length of the part of the third transmission belt 2146 between them also begins to increase. Overall, when the movable support member 211 moves relative to the device support base 400, the first base 111 moves relative to the movable support member 211.

[0070] To further optimize the above technical solution, in an embodiment of the present application, as Figure 5 and Figure 6As shown, the first-level transmission mechanism 213 further includes two tension wheels 2133. The two tension wheels 2133 are respectively located on both sides of the driving wheel 2131, that is, on the side of the driving wheel 2131 close to the first working station and on the side close to the second working station. The second end of the first transmission belt 2132 bypasses the driving wheel 2131 and the two tension wheels 2133 and then is connected to the second end of the moving support member 211. And the driving wheel 2131 is located on one side of the first transmission belt 2132, and the two tension wheels 2133 are located on the other side of the first transmission belt 2132. By respectively arranging the tension wheels 2133 on both sides of the driving wheel 2131, the wrap angle of the first transmission belt 2132 relative to the driving wheel 2131 can be made larger, that is, the contact area between the first transmission belt 2132 and the driving wheel 2131 is larger, avoiding slipping and making the transmission more stable.

[0071] Furthermore, a tensioning mechanism is also provided at the first transmission wheel 2141 and / or the second transmission wheel 2142 of the second-level transmission mechanism 214. This tensioning mechanism is used to make the wrap angle of the second transmission belt 2145 relative to the first transmission wheel 2141 larger and / or to make the wrap angle of the third transmission belt 2146 relative to the second transmission wheel 2142 larger.

[0072] As Figures 1 to 3 shown, in an embodiment of the present application, the driving assembly 200 further includes a second driving device 220 for driving the second base 112 to reciprocate between the second working station and the third working station. The second driving device 220 includes a plurality of driving piston cylinders. Each driving piston cylinder is connected in series to form a driving piston cylinder group. One end of the driving piston cylinder group is connected to the device support base 400, and the other end is connected to the second base 112.

[0073] Specifically, the second driving device 220 includes a first driving piston cylinder 221 and a second driving piston cylinder 222. The cylinder block of the first driving piston cylinder 221 is fixedly connected to the cylinder block of the second driving piston cylinder 222. The piston rod of the first driving piston cylinder 221 and the piston rod of the second driving piston cylinder 222 extend in opposite directions coaxially or parallelly. The piston rod of the first driving piston cylinder 221 is connected to the device support base 400, and the piston rod of the second driving piston cylinder 222 is connected to the second base 112.

[0074] Of course, it should be noted that the first driving device 210 and the second driving device 220 are not limited to the above structures and can be designed according to actual situations as long as reciprocating movement can be achieved.

[0075] To improve the stability of the driving piston cylinder group during driving, in an embodiment of the present application, as Figure 2 and Figure 3As shown, the second driving device 220 further includes a sliding support mechanism, which includes a support slide rail 224 and a support slider 223. Among them, the support slide rail 224 is arranged on the device support base 400, and the support slider 223 is arranged on the cylinder block of the first driving piston cylinder 221 and / or the cylinder block of the second driving piston cylinder 222, and the support slider 223 is slidably matched with the support slide rail 224.

[0076] In order to improve the accurate positioning of the plate-like parts during transportation, in an embodiment of the present application, the plate-like part conveying device further includes a positioning detection device, which includes a first trigger, a second trigger and a sensor. Among them, the first trigger is arranged on the first base 111, the second trigger is arranged on the second base 112, and sensors are respectively arranged at the positions corresponding to the first station, the second station and the third station. The sensor is used to control the first driving device 210 to stop when the first trigger is sensed, and control the second driving device 220 to stop when the second trigger is sensed. The trigger includes, but is not limited to, a photoelectric sensor, a proximity switch, etc.

[0077] The first lifting device 121 and the second lifting device 122 are used to drive the plate-like parts to lift, and can be realized by various structures, such as a piston cylinder, which can be an air cylinder or a hydraulic cylinder. It can also include a rotating motor and a transmission mechanism, and the transmission mechanism is used to convert the rotation of the rotating motor into a linear reciprocating movement. The transmission mechanism includes, but is not limited to, a gear rack mechanism, a lead screw slider mechanism and a cam link mechanism. In a specific embodiment of the present application, the first lifting device 121 and the second lifting device 122 include a plurality of lifting piston cylinders.

[0078] Preferably, in an embodiment of the present application, the first positioning device 131 and the second positioning device 132 include a positioning support frame, and the positioning support frame is provided with positioning pins and / or positioning surfaces. The positioning pins are used to cooperate with the predetermined holes of the plate-like parts, and the positioning surfaces are used to cooperate with the surface of the plate-like parts.

[0079] As Figure 7 As shown, in a specific embodiment, the first base 111 adopts a frame structure. The first lifting device 121 includes four lifting piston cylinders, and the four lifting piston cylinders are respectively arranged at the four corners of the first base 111. The cylinder block of the lifting piston cylinder is fixed on the first base 111, and the piston rod of the lifting piston cylinder is connected to the positioning support frame serving as the first positioning device 131. The positioning support frame is arranged above the first base 111, and positioning pins and positioning surfaces are arranged on the positioning support frame. The structures of the second base 112, the second lifting device 122 and the second positioning device 132 are basically the same as the layout structures of the above-mentioned first base 111, the first lifting device 121 and the first positioning device 131.

[0080] As Figures 1 to 3As shown, in an embodiment of the present application, the clamping and fixing assembly 300 includes a clamping support base 310 and a quick clamp 320. Among them, a support surface for contacting and cooperating with plate-like parts is provided at the top of the clamping support base 310. The quick clamp 320 is arranged on the clamping support base 310, and the quick clamp 320 cooperates with the support surface to clamp and fix the plate-like parts.

[0081] Of course, it should be noted that since the area of the plate-like parts is large, in order to achieve stable support for the plate-like parts, the clamping and fixing assembly 300 further includes an auxiliary support base. A support surface for contacting and cooperating with the plate-like parts is provided at the top of the auxiliary support base, but there is no need to set the quick clamp 320, and it only needs to play an auxiliary support role for the plate-like parts.
