Description

Technical Field

[0001] This application relates to the technical field of thermos bottle production equipment, and more specifically, it relates to a device for inspecting and unloading thermos bottle bodies after welding with discs. Background Technology

[0002] In the production of thermos flasks, vents are typically placed on the bottom surface of the flask body to allow for subsequent venting and create a vacuum layer. After the gas is released, the vents need to be sealed. This is usually done with glue. However, since the flask body is typically made of metal, using glue can create an unsightly material difference on the bottom surface. Therefore, a circular groove is usually created on the bottom surface of the flask corresponding to the vent. After sealing the vent with glue, a circular piece is welded into the groove to cover the glue, thus forming a more aesthetically pleasing, uniform metal outer surface of the flask body.

[0003] The welding of the thermos bottle body and the disc is usually done on a welding table. After welding, the welding effect needs to be checked. In related technologies, the bottle body and disc are usually loaded onto the welding table manually and welded by the resistance welding structure on the welding table. After welding, the disc is unloaded manually. During the unloading process, a hand-held suction cup is attached to the disc and pulled along the height of the bottle body to check if the disc is loose, thus checking the welding effect. Using the above method, the welding effect is checked manually. The labor intensity of the employees is high, and the force applied manually is unstable. It is easy to apply too much force, which will damage the disc, or apply too little force, which will result in inaccurate test results. Utility Model Content

[0004] To address the problem that manually inspecting the welding effect of the bottle body and the disc is labor-intensive and prone to inaccurate results due to unstable manual force, this application provides a device for inspecting and unloading the bottle body and disc after welding.

The two pneumatic grippers are arranged along the X-axis. Each pneumatic gripper includes a double-rod cylinder and two clamping blocks. A clamping block is fixed to the end of each of the two telescopic rods of the double-rod cylinder, and the opposing surfaces of the two clamping blocks are concave surfaces that match the bottle body.

[0010] Preferably, the sorting and unloading mechanism includes a lifting assembly, a two-stage pushing assembly, a transfer table, a defective product collection table, a defective product pushing assembly, and a belt conveyor. The lifting assembly is located on the side of the inspection table away from the welding table and is arranged parallel to the inspection table along the X-axis and within the range of motion of the pneumatic gripper. The lifting assembly is used to drive the bottle body to lift and lower. The transfer table is located on the side of the lifting assembly away from the inspection table and is arranged parallel to the lifting assembly along the X-axis. The defective product collection table is arranged parallel to the transfer table along the Y-axis. The belt conveyor is located on the side of the transfer table away from the lifting assembly. The two-stage pushing assembly is installed on the lifting assembly to push the bottle body on the lifting assembly onto the transfer table and to push the bottle body from the transfer table onto the belt conveyor. The defective product pushing assembly is fixed on the transfer table to push the bottle body on the transfer table toward the defective product collection table.

[0011] Preferably, the lifting assembly includes a connecting frame, a lifting platform, and a third cylinder.

[0015] The beneficial technical effects of this application are as follows: When transferring the bottle body with the welded disc on the welding table via the clamping and transfer mechanism, the bottle body is automatically fed onto the detection table. The positioning groove on the detection table positions and limits the horizontal movement of the bottle body. The pressure sensor driven by the first cylinder rises, causing the fixing block and suction cup to rise, so that the suction cup passes through the opening and adsorbs the disc welded to the bottle body. The pressure sensor driven by the first cylinder falls, causing the fixing block and suction cup to fall, so that the suction cup pulls down the disc, realizing the detection of the disc. The control system is set with a pressure value. When the pressure value does not reach the preset value, it indicates that the welding is unqualified, and the suction cup releases the adsorption of the disc. When the pressure value reaches the preset value, it indicates that the welding is qualified. The pressure sensor realizes the pressure sensing setting, which facilitates the constant force detection of the welding effect of the bottle body and the disc. The control system controls the sorting and unloading mechanism to transport qualified products on the welding table to one position for collection and unqualified products to another position for collection, realizing the automatic unloading of the bottle body. The constant force detection of the welding effect of the bottle and disc is achieved by the cooperation of the cylinder, suction cup and pressure sensor. Compared with the manual force detection by the suction cup, the detection result is more accurate. The clamping and transfer mechanism places the bottle from the welding table to the detection table and then transfers the detected bottle to the sorting and unloading mechanism. Finally, the sorting and unloading mechanism sorts and unloads the bottle automatically, which reduces the labor intensity of the employees. Attached Figure Description

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] Reference Figure 1 A device for inspecting and unloading a thermos bottle body after welding with a circular piece includes a workbench 1 and a control system. A welding table 2 is provided on the workbench 1, and a resistance welding structure is provided on the welding table 2 to weld the bottle body and the circular piece. Specifically, a placement groove matching the bottom contour of the bottle body is provided on the top surface of the welding table 2, and a clearance hole is provided at the bottom of the placement groove. A chamber is provided at the bottom of the welding table 2, and the clearance hole connects to the chamber. The resistance welding structure is installed in the chamber. The resistance welding structure includes a welding needle and a lifting drive component. The welding needle is aligned with the clearance hole, and the lifting drive component is connected to the welding needle to drive the welding needle to rise and fall. The welding needle is connected to an external power source. During welding, the circular piece is placed at the position of the alignment hole, and then the bottle body is placed in the placement groove to combine the bottle body and the circular piece. The lifting drive component drives the welding needle to rise, allowing the welding needle to contact the circular piece. The lifting drive component is preferably a linear module. Current is applied by an external power source, enabling the welding needle to weld the bottle body and the circular piece through resistance heating.

[0023] Reference Figure 1 and Figure 3The workbench 1 is also equipped with a detection table 3, a sorting and unloading mechanism 4, and a clamping and transferring mechanism 5. The welding table 2, the detection table 3, and the sorting and unloading mechanism 4 are arranged sequentially along the X-axis on the top of the workbench 1. The clamping and transferring mechanism 5 is used to transfer the bottle from the welding table 2 to the detection table 3 and from the detection table 3 to the sorting and unloading mechanism 4. The top of the detection table 3 is recessed with a positioning groove 31 that matches the bottom contour and size of the bottle. The middle of the detection table 3 is provided with an installation cavity 32. A vertical first cylinder 33 is fixed in the installation cavity 32. A pressure sensor 34 is provided at the top of the telescopic shaft of the first cylinder 33. The sensing end of the pressure sensor 34 is connected to a fixing block 35. A suction cup 36 is provided on the fixing block 35. The bottom surface of the positioning groove 31 has an opening that connects to the installation cavity 32. The opening aligns with the suction cup 36 so that the suction cup 36 can pass through and out. The first cylinder 33, the pressure sensor 34, the suction cup 36, the sorting and unloading mechanism 4, and the clamping and transferring mechanism 5 are all connected to the control system. The system signal connection is established. The clamping and transfer mechanism 5 clamps and transfers the welded bottle body in the placement slot on the welding table 2 to the positioning groove 31 of the detection table 3. The detection table 3 drives the pressure sensor 34 to rise through the first cylinder 33, which in turn drives the fixing block 35 and the suction cup 36 to rise, so that the suction cup 36 passes through the opening and adsorbs the circular piece welded to the bottle body. Then, the first cylinder 33 drives the pressure sensor 34 to fall, which in turn drives the fixing block 35 and the suction cup 36 to fall, so that the suction cup 36 pulls down the circular piece, realizing the detection of the circular piece. The control system is set with a pressure value. When the pressure value does not reach the preset value, it means that the welding is unqualified, and the suction cup 36 releases the adsorption of the circular piece. When the pressure value reaches the preset value, it means that the welding is qualified. The pressure sensor 34 realizes the pressure sensing setting, which facilitates the constant force detection of the welding effect of the bottle body and the circular piece. The constant force detection is more accurate than the manual force detection using the suction cup 36. After the welding effect is inspected by the inspection table 3, the bottle body is transferred from the welding table 2 to the sorting and unloading mechanism 4 by the clamping and transfer mechanism 5. Finally, the bottle body is sorted and unloaded by the sorting and unloading mechanism 4, and the bottle body is automatically unloaded, thereby reducing the labor intensity of employees.

[0024] Reference Figure 1 and Figure 2Furthermore, the clamping and transfer mechanism 5 includes a three-axis moving frame and pneumatic grippers. The three-axis moving frame includes a frame body 51, a Y-axis slide 52, an X-axis slide 53, and a Z-axis slide 54. The frame body 51 is located on one side of the welding table 2, the inspection table 3, and the sorting and unloading mechanism 4. A Y-axis slide rail is provided on the frame body 51, and a Y-axis slider 521 is provided on the Y-axis slide 52. The Y-axis slider 521 is slidably connected to the Y-axis slide rail 511 to realize the reciprocating sliding of the Y-axis slide 52 along the Y-axis direction. A first lead screw 512 parallel to the Y-axis is rotatably provided on the frame body 51. The first lead screw 512 is parallel to the Y-axis and threadedly connected to the Y-axis slide 52. A first servo motor 513 is also provided on the frame body 51. The first servo motor 513 is used to drive the first lead screw 512 in both forward and reverse directions. The rotation drives the Y-axis slide 52 to reciprocate along the Y-axis direction, and the displacement of the Y-axis slide 52 is precise. The control system is connected to the first servo motor 513, and the control system controls the Y-axis slide 52 to automatically reciprocate along a predetermined path. An X-axis slide rail 522 is provided on the Y-axis slide 52, and an X-axis slider 531 is provided on the X-axis slide 53. The X-axis slider 531 is slidably connected to the X-axis slide rail 522 to achieve the reciprocating movement of the X-axis slide 53 along the X-axis direction. A second lead screw 523 parallel to the X-axis is rotatably mounted on the Y-axis slide 52. A second servo motor 524 is also provided on the Y-axis slide 52, and the second servo motor 524 is connected to the second lead screw 523 to drive the second lead screw 523 to rotate in both directions, thereby driving the X-axis slide... The X-axis slide 53 reciprocates along the X-axis direction, with precise displacement. The control system is connected to the second servo motor 524, enabling the X-axis slide 53 to automatically reciprocate along a predetermined path. A Z-axis slide rail 532 is mounted on the X-axis slide 53, and a Z-axis slider 541 is mounted on the Z-axis slide 54. The Z-axis slider 541 is slidably connected to the Z-axis slide rail 532, allowing the Z-axis slide 54 to reciprocate along the Z-axis direction. A vertical second cylinder 533 is mounted on the X-axis slide 53, with its extension shaft connected to the Z-axis slide 54. Driven by the second cylinder 533, the Z-axis slide 54 automatically moves along the Y-axis direction. The second cylinder 533 is connected to the control system, enabling the Z-axis slide 54 to move automatically along the Y-axis direction. The Z-axis slide 54 automatically reciprocates along a predetermined path. The pneumatic gripper is fixed on the Z-axis slide 54 to grip or release the bottle. The movement of the Y-axis slide 52 drives the X-axis slide 53, Z-axis slide 54, and pneumatic gripper to move along the Y-axis, so that the pneumatic gripper moves to the position of the alignment welding table 2, the inspection table 3, and the sorting and feeding mechanism. The movement of the X-axis slide 53 drives the Z-axis slide 54 and pneumatic gripper to move along the X-axis, so that the pneumatic gripper is close to the bottle and grips it. The movement of the Z-axis slide 54 drives the pneumatic gripper to move along the Z-axis, so that the pneumatic gripper lifts the bottle and moves it away from the placement slot of the welding table 2 to avoid it. During placement, the bottle is placed from top to bottom.

[0025] Reference Figure 1 and Figure 2 Furthermore, there are two pneumatic grippers. A rotary cylinder 542 is also installed on the Z-axis slide 54. One pneumatic gripper is fixed to the Z-axis slide 54, and the other pneumatic gripper is connected and fixed to the rotation shaft of the rotary cylinder 542. The rotary cylinder 542 drives the pneumatic gripper to rotate 180°, thus rotating the bottle 180° so that the bottom of the bottle faces upwards. The two pneumatic grippers are arranged along the X-axis, and their spacing matches the spacing between the placement groove on the welding table 2 and the positioning groove 31 on the inspection table 3. The bottles on welding table 2 move to inspection table 3 and the bottles on inspection table 3 move to sorting and unloading mechanism 4 simultaneously, which improves the efficiency of bottle transfer. The pneumatic grippers of rotary cylinder 542 are aligned with inspection table 3 during operation, so that the bottles are flipped after inspection and placed on sorting and unloading mechanism 4. This is beneficial for subsequent grinding of the discs. Both the double-rod cylinder 55 and the rotary cylinder 542 are connected to the control system and are controlled by the control system to operate automatically.

[0026] Reference Figure 2 Furthermore, the pneumatic gripper includes a double-rod cylinder 55 and two gripping blocks 56. Each of the two telescopic rods of the double-rod cylinder 55 has a gripping block 56 fixed to its end, and the opposing surfaces of the two gripping blocks 56 are concave surfaces that match the bottle body. The two gripping blocks 56 move towards each other to clamp and fix the bottle body by retracting the two telescopic rods of the double-rod cylinder 55 in sync. The two gripping blocks 56 move away from each other to clamp the bottle body by extending the two telescopic rods of the double-rod cylinder 55 in sync. The concave surfaces of the gripping blocks 56 are designed to increase the contact area with the bottle body, making the clamping more stable.

[0027] Reference Figure 1 and Figure 4Furthermore, the sorting and unloading mechanism 4 includes a lifting assembly 41, a double-stage pushing assembly 42, a transfer table 43, a defective product collection table 44, a defective product pushing assembly 45, and a belt conveyor 46. The lifting assembly 41 is located on the side of the inspection table 3 away from the welding table 2 and is arranged parallel to the inspection table 3 along the X-axis direction, within the range of motion of the pneumatic grippers. The transfer table 43 is located on the side of the lifting assembly 41 away from the inspection table 3 and is arranged parallel to the lifting assembly 41 along the X-axis direction. The defective product collection table 44 and the transfer table 46 are arranged parallel to each other. The transfer stations 43 are arranged side by side along the Y-axis. The belt conveyor 46 is located on the side of the transfer station 43 away from the lifting assembly 41. The bottle body inspected by the inspection station 3 is clamped and transferred to the lifting assembly 41 by the clamping and transfer mechanism 5. The double-stage pushing assembly 42 is installed on the lifting assembly 41, and the defective product pushing assembly 45 is fixed on the transfer station 43. In the above structure, the bottle body inspected by the inspection station 3 is clamped and transferred to the lifting assembly 41 by the clamping and transfer mechanism 5. The lifting assembly 41 is used to drive the bottle body. The lifting mechanism allows the bottle to adapt to the height difference between the testing platform 3 and the transfer platform 43. After the lifting component 41 drives the bottle to descend to the same height as the transfer platform 43, the double-stage pushing component 42 first pushes the bottle on the lifting component 41 onto the transfer platform 43. If the bottle is welded and qualified, the double-stage pushing component 42 pushes it onto the belt conveyor 46 for transport to the next process or directly for collection. If the bottle is welded and unqualified, it is pushed onto the defective product collection platform 44 by the defective product pushing mechanism set on the transfer platform 43 for collection. The qualified and unqualified bottles are sorted by diversion and conveying. The lifting component 41, the double-stage pushing component 42, the defective product pushing component 45 and the belt conveyor 46 are all connected to the control system signal and operate automatically under the control system. During sorting, the control system judges whether the product is qualified based on the pressure value fed back by the pressure sensor 34 and controls the corresponding components to operate to achieve precise diversion and conveying.

[0028] Reference Figure 1 Furthermore, the lifting assembly 41 includes a connecting frame 411, a lifting platform 412, and a third cylinder 413. The connecting frame 411 is provided with a vertical slide rail 414, which is parallel to the Z-axis. The lifting platform 412 is provided with a vertical slider 415, which is slidably connected to the vertical slide rail 414, so that the lifting platform 412 can slide back and forth along the Z-axis to lift and lower. The third cylinder 413 is fixed on the connecting frame 411 and connected to the lifting platform 412 to drive the lifting platform 412 to lift and lower automatically. The third cylinder 413 is connected to the control system signal and is controlled by the control system to operate automatically. The bottle on the detection platform 3 is transferred to the lifting platform 412 through the clamping and transfer mechanism 5. The lifting platform 412 is driven to lift and lower by the third cylinder 413 to be flush with the detection platform 3 and the transfer platform 43.

[0029] Reference Figure 4Furthermore, the dual-stage pushing assembly 42 includes a fourth cylinder 421, a fifth cylinder 422, a first pusher block 423, a first connector 424, and a second connector 425. The first connector 424 is disposed on the telescopic shaft of the fourth cylinder 421. The fifth cylinder 422 is connected and fixedly connected to the first connector 424. The telescopic shafts of the fourth cylinder 421 and the fifth cylinder 422 are arranged parallel to each other and face the same direction. The second connector 425 is disposed on the telescopic shaft of the fifth cylinder 422. The first pusher block 423 is connected and fixedly connected to the second connector 425. The side wall of the lifting platform 412 is recessed with a receiving cavity, which extends through the opposite sides of the lifting platform 412 along the X-axis. The fourth cylinder 421 is laterally fixed to the bottom surface of the receiving cavity, and its telescopic shaft faces the detection table 3. The first pusher block 423 is located between the welding table 2 and the lifting table 412 and above the top surface of the lifting table 412. When the bottle on the lifting table 412 is pushed towards the transfer table 43, the telescopic shaft of the fifth cylinder 422 extends, driving the first pusher block 423 to move towards the transfer table 43, thus pushing the bottle onto the transfer table 43. When the bottle on the transfer table 43 is pushed towards the belt conveyor 46, the telescopic shaft of the fourth cylinder 421 extends, driving the fifth cylinder 422 and the first pusher block 423 to move towards the belt conveyor 46, thus pushing the bottle on the transfer table 43 onto the belt conveyor 46. The two cylinders drive the first pusher block 423 to achieve double-stage pushing. Both the fourth cylinder 421 and the fifth cylinder 422 are connected to the control system signal.

[0030] Reference Figure 1Furthermore, the top surface of the transfer platform 43 is recessed with a first chute 431 extending along the X-axis and penetrating its opposite sides. The defective product collection platform 44 is provided with a second chute 441 extending along the Y-axis and penetrating its opposite sides. The first chute 431 and the second chute 441 are connected, and the widths of both chute 431 and chute 441 match the width of the bottle. When the dual-stage pushing mechanism pushes the bottle from the lifting platform 412 to the transfer platform 43, it pushes it to the connection point of the first chute 431 and the second chute 441. The chute limits the bottle's position, preventing it from easily deviating during the pushing process, facilitating its movement along a precise path, and ensuring the bottle accurately falls onto the belt conveyor 46. The defective product pushing assembly 45 is installed... Mounted on the side of the transfer platform 43 away from the defective product collection platform 44, the defective product pushing assembly 45 includes a sixth cylinder 451 and a second pusher block 452. The sixth cylinder 451 is connected and fixed to the transfer platform 43, and its telescopic shaft faces the defective product collection platform 44. The second pusher block 452 is set on the telescopic shaft of the sixth cylinder 451 and aligned with the second slide groove 441. The sixth cylinder 451 drives the second pusher block 452 to move towards the defective product collection platform 44, so that the second pusher block 452 pushes the defective bottles onto the second slide groove 441 for collection. Several defective bottles with defective welding are pushed to the same position by the second pusher block 452, so that the next bottle pushes the previous one forward, so that the defective bottles are arranged on the second slide groove 441 for collection.
