[0037] A vacuum flask production line, see Figure 1 , including a feeding device 100, a plurality of grinding devices 300 and a plurality of polishing devices 700 which are sequentially arranged and used to convey the thermos cups one by one, and also including a plurality of manipulators 200 and a control device 27, wherein the plurality of grinding devices 300 and the plurality of polishing devices 700 are respectively arranged in one-to-one correspondence with the plurality of manipulators 200; the feeding device 100, the grinding device 300, the polishing device 700 and the manipulator 200 are respectively electrically connected to the control device 27. In this embodiment, three grinding devices 300, four polishing devices 700 and seven manipulators 200 are arranged, and the manipulators 200 are six-axis manipulators 200, and the three grinding devices 300 and the four polishing devices 700 are arranged side by side, and a placement rack 10 for placing the thermos cups is installed between them, so that the manipulators 200 can place the thermos cups.

[0038] When the equipment is working, the staff puts multiple thermos cups on the feeding device 100, and then the control device 27 controls the feeding device 100 to transport the thermos cups one by one, and then several manipulators 200 grab the thermos cups in turn, and grind the welds of the thermos cups through multiple grinding devices 300, and polish the surface of the thermos cups through multiple polishing devices 700, and then the feeding is completed. The whole process does not require manual operation, and the staff only needs to place and collect the thermos cups, which saves time and labor, has high work efficiency, high consistency, and reduces production costs.

[0039] See also Figures 2 to 6 Specifically, the feeding device 100 includes:

[0040] A conveying platform 1, wherein the conveying platform 1 is provided with a clamping point 11 and a conveying assembly 12 for conveying the thermos cups to the clamping point 11 one by one;

[0041] A loading platform, which is located on one side of the conveying platform 1 and is provided with a supporting seat 21 for carrying a thermos cup, a clamping device 22 for clamping and rotating the thermos cup, and a visual alignment mechanism 23 for detecting the position of the weld of the thermos cup;

[0042] A gripping mechanism 26, the gripping mechanism 26 is used to transfer the thermos cup at the clamping point 11 to the supporting seat 21;

[0043] The visual alignment mechanism 23 is electrically connected to a signal input end of a control device 27 , and the clamping device 22 and the grasping mechanism 26 are electrically connected to signal output ends of the control device 27 , respectively.

[0044] When the loading device 100 is working, the worker only needs to place the batch of thermos cups upright on the conveying platform 1, and then the control device 27 adjusts the conveying component 12 to convey the thermos cups to the clamping point 11 one by one, and then the control device 27 adjusts the grasping mechanism 26 to transfer the thermos cups at the clamping point 11 to the supporting seat 21, and then the control device 27 adjusts the clamping device 22 to clamp the thermos cup and rotate it, and cooperates with the visual alignment mechanism 23 to make the weld of the thermos cup rotate to the position where the visual alignment mechanism 23 recognizes the weld, so as to facilitate the external manipulator 200 to clamp the thermos cup and process the weld at that position, saving time and labor, realizing automatic loading, and reducing factory production costs.

[0045] Specifically, the conveying assembly 12 includes a conveyor belt 121 and a first drive motor 122 rotatably connected to the conveying platform 1. The conveying platform 1 is provided with a block 13 surrounding the conveyor belt 121. The block 13 is provided with an opening 14 on one side of the terminal end of the conveyor belt 121. The block 13 is provided with a switch cylinder 15. The output shaft of the switch cylinder 15 is provided with a baffle for blocking the opening 14. The clamping point 11 is located at the opening 14. In this embodiment, the end of the block 13 close to the opening 14 is narrowed in a funnel shape so that the thermos cups can pass through one by one. The switch cylinder 15 is electrically connected to the signal output end of the control device 27.

[0046] The block 13 can prevent the thermos cup from falling outside the conveyor belt 121. When the conveying component 12 is working, the conveyor belt 121 continuously transports the thermos cup to the opening 14. Then the control device 27 regulates the switch cylinder 15 to drive the baffle to block the opening 14 each time a thermos cup passes through the clamping point 11, and then drives the baffle to block the opening 14 to prevent subsequent thermos cups from leaving the opening 14. After the control device 27 regulates the grabbing mechanism 26 to take away the thermos cup, it regulates the switch cylinder 15 to drive the baffle to open the opening 14, so that subsequent thermos cups can enter the clamping point 11 one by one.

[0047] Specifically, the clamping device 22 includes a first sliding plate 221 and a second sliding plate 222 that are slidably connected to the loading platform and are relatively arranged on both sides of the supporting seat 21. The loading platform is provided with a first driving member 223 that drives the first sliding plate 221 and the second sliding plate 222 to move closer to and away from each other. The first sliding plate 221 is rotatably connected to an abutment seat 224, and the second sliding plate 222 is rotatably connected to an abutment cylinder 225. The second sliding plate 222 is provided with a second driving member 226 that drives the abutment cylinder 225 to rotate. In this embodiment, the first driving member 223 and the second driving member 226 are respectively electrically connected to the signal output end of the control device 27, the first driving member 223 is a first cylinder 33, and the second driving member 226 is a servo motor 761.

[0048] When the control device 27 adjusts the grabbing mechanism 26 to place the thermos cup on the supporting seat 21, the first driving member 223 then drives the first sliding plate 221 and the second sliding plate 222 to approach each other, so that the thermos cup is clamped between the abutment seat 224 and the abutment tube 225, and then the second driving member 226 drives the abutment tube 225 to rotate, thereby achieving the purpose of adjusting the weld of the thermos cup.

[0049] Specifically, the support seat 21 is slidably connected to the loading platform, the loading platform is provided with a push cylinder 227 for driving the support seat 21 to slide, the loading platform is installed with a discharge cylinder 24 for abutting against the thermos cup on the support seat 21, the loading platform is provided with a discharge trough 25, the discharge trough 25 and the discharge cylinder 24 are arranged oppositely and are respectively located on both sides of the support seat 21. In this embodiment, the push cylinder 227 and the discharge cylinder 24 are respectively electrically connected to the signal output end of the control device 27.

[0050] When the visual alignment mechanism 23 fails to detect the weld of the thermos cup or an abnormality occurs, the control device 27 controls the push cylinder 227 to drive the support seat 21 to slide to the side of the discharge chute 25, and then the control device 27 controls the discharge cylinder 24 to extend, and removes the thermos cup on the support seat 21 to the discharge chute 25 for subsequent detection of the weld of the thermos cup. When the next thermos cup is clamped on the support seat 21, the push cylinder 227 drives the support seat 21 back to the clamping device 22 so that the abutment tube 225 and the abutment seat 224 can clamp it.

[0051] Specifically, the support seat 21 includes a third sliding plate 211 slidably connected to the upper surface of the loading platform, the third sliding plate 211 is slidably connected to a receiving plate 212 in a direction perpendicular to the upper surface of the loading platform, the receiving plate 212 is provided with a plurality of V-shaped clamping plates 213 distributed in parallel and used to abut against the thermos cup, and the third sliding plate 211 is provided with a third driving member 214 driving the receiving plate 212 to slide. In this embodiment, the third driving member 214 is electrically connected to the signal output end of the control device 27.

[0052] Since the sizes of the processed thermos cups are different, it is convenient for the control device 27 to adjust the third driving member 214 to drive the V-shaped clamping plate 213 to slide up and down, so as to better receive the thermos cup removed from or installed on the clamping device 22.

[0053] Specifically, the grasping mechanism 26 is a three-axis manipulator.

[0054] Specifically, the visual alignment mechanism 23 is a CCD visual inspection machine.

[0055] Specifically, it also includes an input device 29 electrically connected to the signal input end of the control device 27 and a display 28 electrically connected to the signal output end of the control device 27. In this embodiment, the input device 29 is a mouse and a keyboard, which is convenient for the operator to control the operation of the device.

[0056] See also Figures 7 to 9 Specifically, the grinding device 300 includes a grinding table 3 and a crossbeam 31, the grinding table 3 is provided with a chassis 4, the crossbeam 31 is installed with a grinding assembly 5 for grinding a workpiece, a plurality of swing rods 32 parallel to each other are hinged between the crossbeam 31 and the grinding table 3, the plurality of swing rods 32 are arranged inside the chassis 4, and the swing rods 32 and the inner wall of the chassis 4 are abutted and matched, the grinding table 3 is installed with a first cylinder 33, the output shaft of the first cylinder 33 is provided with an abutment block 34 abutting and matching with the side of the swing rod 32, and the output shaft of the first cylinder 33 faces the side of the grinding assembly 5 for grinding the workpiece.

[0057] When an error occurs in the operation of the manipulator 200, so that the clamped workpiece is slightly far away from the grinding assembly 5, because the crossbeam 31 is hinged to the grinding table 3 through multiple swing rods 32, the output shaft of the first cylinder 33 is extended, thereby pushing the swing rod 32 to rotate a certain angle, so that the grinding assembly 5 is close to the workpiece clamped by the manipulator 200, thereby compensating for the processing error; when an error occurs in the operation of the manipulator 200, so that the clamped workpiece is too close to the grinding assembly 5, the output shaft of the first cylinder 33 is contracted, so that the grinding assembly 5 is under the reaction force of the workpiece clamped by the manipulator 200, so that the crossbeam 31 rotates a certain angle around the swing rod 32, thereby avoiding the problem that the position of the grinding assembly 5 is fixed, and then the workpiece is too close to the grinding assembly 5, resulting in scrapping or damage to the grinding equipment; the setting of the first cylinder 33 also provides a constant throwing pressure for the grinding assembly 5 to grind the workpiece. Multiple swing rods 32 are arranged in the chassis 4, and the inner wall of the chassis 4 abuts against the swing rod 32, which can limit the rotation angle of the swing rod 32.

[0058] Specifically, the grinding assembly 5 includes a grinding wheel 51 and a transmission wheel 52 which are connected to the crossbeam 31 and rotate in sequence along the length direction of the crossbeam 31. The grinding wheel 51 and the transmission wheel 52 are sleeved with a grinding belt 53. The crossbeam 31 is provided with a first driving device 35 for driving the grinding wheel 51 to rotate. In this embodiment, the first driving device 35 is a synchronous belt mechanism driven by a motor (not shown in the figure).

[0059] Specifically, it also includes an adjusting wheel 36 abutting against the inner side of the grinding belt 53, the crossbeam 31 is slidably connected to an adjusting seat 37, the adjusting seat 37 slides along the direction of approaching and moving away from the line between the grinding wheel 51 and the transmission wheel 52, the adjusting wheel 36 is rotatably connected to the adjusting seat 37, and the crossbeam 31 is provided with a second driving device 38 for driving the adjusting seat 37 to slide.

[0060] Since the sanding belt 53 will gradually loosen after being used for a period of time, the setting of the adjusting wheel 36 can be driven by the second driving device 38 to slide in the direction away from the connection line between the grinding wheel 51 and the transmission wheel 52, thereby achieving the purpose of tightening the sanding belt 53. In addition, the adjusting wheel 36 can also be slid in the direction close to the connection line between the grinding wheel 51 and the transmission wheel 52 to achieve the purpose of removing the sanding belt 53. In this embodiment, the second driving device 38 is a second cylinder 822.

[0061] Specifically, the chassis 4 is provided with a plurality of buffer blocks 41 that abut against the swing rod 32 . The provision of the buffer blocks 41 can reduce the noise of abutment and collision between the swing rod 32 and the inner wall of the chassis 4 , and reduce damage to the swing rod 32 .

[0062] Specifically, the grinding table 3 is provided with a slag trough 6, and the slag trough 6 is installed directly below the grinding wheel 51. The setting of the slag trough 6 can collect and clean the residue of the workpiece, which is clean and convenient.

[0063] In this embodiment, the first cylinder 33 , the first driving device 35 , and the second driving device 38 are electrically connected to the signal output terminals of the control device 27 , respectively.

[0064] See also Figures 10 to 12 Specifically, the polishing device 700 includes a polishing table 7 and a box 71, the polishing table 7 is rotatably connected to a cantilever 72, the cantilever 72 is rotatably connected to a polishing wheel 73, and the cantilever 72 is provided with a first driving mechanism 74 for driving the polishing wheel 73 to rotate;

[0065] It also includes an abutment member 75 that abuts the cantilever 72 away from the workpiece side. The abutment member 75 is slidably connected to the polishing table 7 along the projection direction of the swing trajectory of the cantilever 72 on the polishing table 7. The polishing table 7 is provided with a second driving mechanism 76 that drives the abutment member 75 to slide.

[0066] When the polishing machine is working, the first driving mechanism 74 drives the polishing wheel 73 to rotate. As the usage time increases, the polishing wheel 73 becomes smaller and smaller. The staff starts the second driving mechanism 76 to make the abutment 75 slide and abut against the side of the cantilever 72 away from the workpiece, thereby pushing the polishing wheel 73 to move in the direction close to the workpiece, so as to approach the workpiece and automatically compensate for the polishing accuracy of the polishing wheel 73. Compared with the existing technology, there is no need to replace a new polishing wheel 73 to compensate for the polishing accuracy, which saves more polishing wheels 73 and saves time and effort.

[0067] Specifically, the abutment member 75 is an abutment plate, which is provided with a strip through hole for the cantilever 72 to pass through. The setting of the strip through hole enables the abutment plate to form a frame structure. The setting of the frame structure makes it easy for the abutment plate to abut the cantilever 72 through the opposite inner side walls of the frame when sliding, without the need to set the abutment members 75 on both sides of the cantilever 72 at the same time.

[0068] Specifically, the polishing table 7 is provided with a constant force regulating mechanism 8 which abuts against the cantilever 72 away from and close to either side of the workpiece. The setting of the constant force regulating mechanism 8 facilitates the staff to adjust the pressure between the polishing wheel 73 and the workpiece at any time according to actual conditions, thereby avoiding excessive pressure of the polishing wheel 73 on the workpiece, thereby causing damage to the workpiece.

[0069] Specifically, the constant force regulation mechanism 8 includes an abutment wheel 81, and the polishing table 7 is provided with a third driving mechanism 82 for driving the abutment wheel 81 to abut the cantilever 72. In the present embodiment, the second driving mechanism 76 is a gear rack mechanism 762 driven by a servo motor 761, and the servo motor 761 is installed on the abutment plate. Of course, according to actual conditions, the second driving mechanism 76 can also adopt a screw mechanism driven by a cylinder or a motor. The third driving mechanism 82 is a mounting plate 821 installed on the polishing table 7, and a second cylinder 822 is installed on the mounting plate 821. The abutment wheel 81 is rotatably connected to the output shaft of the second cylinder 822. Of course, according to actual conditions, the third driving mechanism 82 can also adopt a screw mechanism driven by a motor.

[0070] Specifically, the constant force regulating mechanism 8 is arranged on the abutting plate. In this embodiment, the mounting plate 821 is mounted on the abutting plate.

[0071] Specifically, the first driving mechanism 74 includes a second driving motor 741, the cantilever 72 is rotatably connected to a rotating shaft 742, the polishing wheel 73 is installed on the rotating shaft 742, and a synchronous belt transmission assembly (not shown in the figure) is provided between the output shaft of the motor and the rotating shaft 742. The second driving motor 741 drives the synchronous belt transmission assembly to drive the polishing wheel 73 to rotate, thereby avoiding direct connection between the output shaft of the second driving motor 741 and the polishing wheel 73, realizing soft starting, and avoiding the problem of damage to the motor when the load is too large.

[0072] Specifically, the polishing wheel 73 is installed at the upper end of the cantilever 72, and the second drive motor 741 is installed at the lower end of the cantilever 72. In this way, the second drive motor 741 is equivalent to a counterweight installed at the lower end of the cantilever 72, which avoids the situation where the polishing wheel 73 at the upper end of the cantilever 72 swings at the lower end of the cantilever 72 when polishing the workpiece, thereby improving the stability of the polishing machine.

[0073] Specifically, the polishing table 7 is provided with a base 77, and the base 77 is slidably connected with a slider 78 along the projection direction of the swing trajectory of the cantilever 72 on the base 77, and the slider 78 and the lower end of the cantilever 72 are connected with a tension spring 79. This arrangement further improves the stability of the lower end of the cantilever 72. When the lower end of the cantilever 72 is forced to swing, the slider 78 slides and drives the tension spring 79 to extend, and the tension spring 79 converts the force into the elastic force of the tension spring 79, thereby achieving a buffering effect.

[0074] Specifically, it also includes a waste trough 9 installed on the polishing table 7. The waste trough 9 is located directly below the polishing wheel 73. The waste trough 9 is convenient for staff to collect and sort out waste residues.

[0075] In this embodiment, the second cylinder 822 , the second drive motor 741 and the servo motor 761 are electrically connected to the signal output terminals of the control device 27 , respectively.

[0076] The above embodiments are merely explanations of the present invention and are not limitations of the present invention. After reading this specification, those skilled in the art may make modifications to the embodiments without any creative contribution as needed. However, such modifications are protected by the patent law as long as they are within the scope of the claims of the present invention.
