TECHNICAL FIELD

[0001] The application relates to a vacuum cup production technology field, in particular to a vacuum cup mouth welding equipment. BACKGROUND

[0002] With the progress of society and the development of science and technology, people's living standards and quality of life have been significantly improved. Double-layer vacuum cups are favored by consumers because of their hygiene, good insulation effect and long service life. At present, a double-layer vacuum cup generally comprises an inner container and an outer container. During processing, an operator pre-installs the outer container on the outer part of the inner container to form a semi-finished product, then places the semi-finished product on a workbench, and then expands the mouth of the inner container through an expansion mechanism pre-installed above the workbench to make the circumferential wall of the inner container mouth fit the inner wall of the outer container mouth after expansion. Then, a pre-installed welding gun is used to weld the parts where the inner container mouth and the outer container mouth fit each other together to realize the production and manufacturing of the double-layer vacuum cup. The expansion mechanism mentioned above generally comprises a conical block arranged above the workbench and a lifting member for driving the conical block to lift, which drives the conical block to move downward and stamp the inner wall of the inner container mouth to realize the expansion of the inner container mouth.

[0003] For the above-mentioned related technology, since the semi-finished product is placed on the workbench by manual operation, its placement position is not fixed, and if the placement position of the semi-finished product deviates from the position directly below the conical block, the inner wall of the inner container mouth cannot be expanded to fit the inner wall of the outer container mouth, thereby affecting the stability and expansion effect of the inner container mouth. SUMMARY

[0004] In order to accurately place the pre-installed inner container and outer container semi-finished product directly below the expansion mechanism and ensure the stability and expansion effect of the inner container mouth during expansion, the application provides a vacuum cup mouth welding equipment.

[0005] The vacuum cup mouth welding equipment provided by the application adopts the following technical scheme:

[0006] A vacuum cup mouth welding equipment comprises a workbench, a welding mechanism and an expansion mechanism arranged on the workbench, the expansion mechanism is used for inserting into the inner container mouth and expanding the inner container mouth, a positioning assembly is arranged on the workbench, the positioning assembly comprises at least two clamping blocks and a driving member for driving the two clamping blocks to move towards each other or away from each other, a storage space for inserting a cup body is reserved between the two clamping blocks, and the storage space is located directly below the expansion mechanism.

[0007] By adopting the technical scheme, the clamping block is driven by the driving member to move towards each other, so that the cup body is clamped by the clamping block below the flaring mechanism, thereby facilitating the flaring mechanism to be accurately inserted into the inner container cup and to stably flare the circumference of the inner container cup, ensuring the flaring effect and stability, and finally improving the welding stability.

[0008] As preferred, a rotating disc is rotatably connected above the workbench, and a first motor for driving the rotating disc to rotate is arranged on the workbench. The positioning assembly is multiple and arranged along the circumference of the rotating disc. During the rotation of the rotating disc, the positioning assembly on the rotating disc can move below the flaring mechanism with the rotation of the rotating disc.

[0009] By adopting the technical scheme, the positioning assembly is multiple, and all the positioning assemblies are sequentially rotated below the flaring mechanism by the rotation of the rotating disc, thereby realizing the sequential welding of batch cups and improving the automation degree of the processing of batch cups.

[0010] As preferred, a plurality of storage openings are arranged through the rotating disc, and the storage openings are arranged one by one corresponding to the positioning assemblies. The positioning assembly is located at the corresponding storage opening, the cup is inserted into the storage opening, and the positioning assembly clamps the cup in the corresponding storage opening. A blanking opening is arranged on the workbench, and any storage opening is rotated above the blanking opening in the axial direction of the blanking opening and communicates with the blanking opening with the rotation of the rotating disc.

[0011] By adopting the technical scheme, the storage opening not rotated above the blanking opening rotates with the rotation of the rotating disc under the support of the workbench. When any storage opening is rotated to the blanking opening, the clamping of the cup by the driving member is released, and the cup is separated from the sequentially arranged storage opening and blanking opening under the action of gravity, thereby realizing automatic blanking without manual taking and saving time and effort.

[0012] As preferred, the driving member includes a butt joint spring, a butt joint rod and a linkage part. The butt joint spring and the butt joint rod are arranged one by one corresponding to the clamping block.

The butt joint spring is arranged between the clamping block and the butt joint rod, and the extension direction of the butt joint spring is parallel to the length direction of the butt joint rod. The clamping block can abut against the outer wall of the cup under the elastic force of the butt joint spring. The linkage part is used for driving the butt joint rod to rotate, so that the clamping block can abut against the cup or separate from the abutment of the cup when the butt joint rod rotates.

[0013] By adopting the technical scheme, the linkage part is used to drive the abutting rod to rotate and move the clamping block towards the cup body, so that the clamping block is abutted against the outer wall of the cup body by the elastic force of the abutting spring, the cup body is clamped, and conversely, when the cup body needs to be released, the linkage part is used to drive the abutting rod to rotate and move the clamping block away from the cup body, so that the clamping block is separated from the cup body by the elastic force of the abutting spring, and then the cup body located directly below the material falling port can smoothly pass through the material falling port under the action of gravity, and the clamping block reduces the obstruction to the cup body falling.

[0014] Preferably, the positioning assembly further comprises a ring plate, the middle part of the abutting rod is rotationally connected to the ring plate, one end of the abutting rod located at the inner side of the ring plate is connected to the clamping block, and the workbench is provided with a rotating member for driving the ring plate to rotate.

[0015] By adopting the technical scheme, the ring plate is driven to rotate by the rotating member, so that the clamping block drives the cup body clamped thereby to rotate, thereby facilitating the welding mechanism to realize welding on the whole cup body cup opening peripheral wall.

[0016] Preferably, the peripheral wall of the ring plate is provided with a gear slot, the rotating member comprises a driving gear, an abutting gear and a third motor, the driving gear and the abutting gear are both rotationally connected to the workbench, the driving gear is used to engage with the gear slot of the peripheral wall of the ring plate located directly below the flaring mechanism, the abutting gear is used to engage with the driving gear, and the driving end of the third motor is fixedly connected to the rotation center of the abutting gear.

[0017] By adopting the technical scheme, when any placement opening on the rotating disc is turned to be directly below the flaring mechanism, the outer wall of the ring plate in the placement opening will engage with the driving gear, then the abutting gear engages with the driving gear, and then the abutting gear is driven to rotate by the third motor, so that the driving gear drives the ring plate to rotate together, and since the clamping block on the ring plate clamps the cup body, the cup body can rotate together with the ring plate, so as to realize welding on the whole cup body cup opening peripheral wall.

[0018] Preferably, the linkage part comprises a driven gear, a driven rack, a driving ring piece, a driven ring piece and a reset component; the driven gear is coaxially rotationally connected to the workbench, the driven rack engages with the driven gear and is slidingly connected to the workbench, the driving ring piece is arranged on the side wall of the workbench close to the material falling port, the driving ring piece is located on the sliding path of the driven rack, and the side wall of the driving ring piece and the end wall of the driven rack are respectively provided with a displacement arc surface, the displacement arc surface is used to move the driving ring piece upward when the driven rack abuts against the driving ring piece.

[0019] The driven ring piece is arranged one-to-one corresponding to the storage opening and is inserted into the bottom wall of the rotating disc near the corresponding storage opening; when the storage opening is turned to above the material falling opening, the driven ring piece corresponding to the storage opening is located on the moving path of the driving ring piece; one end of the butt joint rod away from the clamping block is located on the moving path of the driven ring piece; the reset component is used to drive the butt joint rod to turn to a state parallel to the radial direction of the storage opening; and the reset component is also used to drive the driving ring piece and the driven ring piece to move away from the butt joint rod.

[0020] By adopting the above technical scheme, when the driving gear rotates to drive the ring plate located directly below the flaring mechanism to rotate to realize the welding of the cup mouth peripheral wall, the driven gear will rotate and drive the driven rack to move towards the driving ring piece, so that the driving ring piece moves up and pushes the driven ring piece located above the material falling opening under the pushing action of the butt joint gear and the accommodation of the accommodation arc surface, the driven ring piece will move up and push the end of the butt joint rod under the pushing of the driving ring piece, so as to realize the rotation of the butt joint rod, so that the clamping block can be separated from the cup body in the process of rotating with the butt joint rod, so that the cup body can pass through the material falling opening to realize the material falling under the action of gravity, and the reset component can reset the driving ring piece and the driven ring piece, and when the driving gear reverses, the driven rack can move away from the driving ring piece under the driving of the driven gear.

[0021] As a preferred, the butt joint gear is always engaged with the driving gear, and the third motor is a brake motor.

[0022] By adopting the above technical scheme, since the ring plate will be engaged with the surface of the driving gear when the rotating disc rotates, it is easy to drive the driving gear to rotate at this time, and a series of movements of the driven rack, the driving ring piece and the like are caused, and at this time, since the rotating disc is rotating, there may not be a storage opening corresponding to the material falling opening above the material falling opening. If the driving ring piece moves up at this time, it will be hindered by the rotating disc, resulting in the tendency of the driving ring piece to move upward, but the movement is hindered. In order to reduce the occurrence of this situation, the application limits the butt joint gear to always engage with the driving gear, and uses the third motor as a brake motor to limit the rotation of the driving gear and the driven gear, so that only when the third motor is started, the driving gear will rotate, that is, only at this time, the driving ring piece will move up.

[0023] As a preferred, the surface of the clamping block is provided with an arc surface, and the arc surface of the clamping block is provided with a flexible pad.

[0024] By adopting the above technical scheme, the arrangement of the flexible pad and the arc surface can ensure the stable clamping of the clamping block to the cup body while reducing the wear degree of the abutting surfaces of the clamping block and the cup body when they abut against each other.

[0025] As a preferred, the workbench is provided below the material falling opening with a conveyor belt, and the surface of the conveyor belt is provided with a buffer pad.

[0026] By adopting the technical scheme, the cup body falling from the material falling port is received by the conveying belt, and the buffer pad is arranged to buffer the cup body, so that the cup body is protected while being automatically conveyed.

[0027] To sum up, the present application has at least one of the following beneficial technical effects:

[0028] 1. The driving member drives the clamping block to move towards each other, so that the cup body is clamped by the clamping block below the flaring mechanism, so that the flaring mechanism can be accurately inserted into the inner container cup opening and stably flared around the inner container cup opening, ensuring the flaring effect and stability, and finally improving the welding stability.

At this time, the inner diameter of the storage space 222 surrounded by all the clamping blocks 22 located in the same storage port 111 is smaller than the outer diameter of any cup body 7, i.e., smaller than the outer diameter of the outer container 6. Therefore, when any cup body 7 with an arbitrary outer diameter is inserted into the storage space 222, the clamping block 22 will abut against the outer wall of the cup body 7 under the elastic force of the docking spring 231, so as to clamp the cup body.

[0040] With reference to Figure 3, the inner part of the rotating disc 11 near each ring plate 21 is provided with a containing cavity 112 for the end of the docking rod 232 to rotate; each ring plate 21 corresponds to a driven ring piece 2334, the driven ring piece 2334 is slidingly connected to the lower surface of the rotating disc 11, and the inner diameter of the driven ring piece 2334 is greater than the caliber of the storage port 111. The reset spring 2337 corresponding to the driven ring piece 2334 is fixedly connected between the driven ring piece 2334 and the rotating disc 11, and the length direction of the reset spring 2337, the sliding direction of the driven ring piece 2334 and the depth direction of the storage port 111 are parallel to each other, when the reset spring 2337 and the reset torsional spring 2336 are not deformed, the corresponding driven ring piece 2334 is located below the docking rod 232 which is in a horizontal state at this time, and the end of the docking rod 232 away from the clamping block 22 is located on the upward moving path of the driven ring piece 2334.

[0041] With reference to Figure 2 and Figure 3 , the number of the driven ring pieces 2333 is one, and the driven ring piece 2333 is slidingly connected below the blanking port 13 of the workbench 1, and the inner diameter of the driven ring piece 2333 is greater than the caliber of the blanking port 13.

It should be noted that during the process of driving the cup body 7 directly below the flaring mechanism 4 to rotate and perform cup mouth peripheral wall welding, in order to make the clamping block 22 disengage from the contact with the cup body 7 before the cup body 7 is welded, the embodiment of the application is specially limited as follows: for example, when the driven ring piece 2334 pushes the end of the abutting rod 232 upwards and makes the clamping block 22 rotate and disengage from the peripheral wall of the cup body 7, at this time the cup body 7 located directly below the flaring mechanism 4 has been rotated more than 180° to complete the welding.

[0043] With reference to Figure 1 And Figure 2 The flaring mechanism 4 includes a conical block 41, a lifting piece 42 and a second motor 43, the driving end of the second motor 43 is connected to the upper end of the conical block 41, the lifting piece 42 is used to drive the conical block 41 and the second motor 43 to lift, the lifting piece 42 can be a combination structure of a motor lead screw, the outer diameter of the conical block 41 gradually decreases from top to bottom, and the outer diameter of the lowermost end of the conical block 41 is smaller than the inner diameter of the cup mouth of the inner container 5 before flaring, and the outer diameter of the uppermost end of the conical block 41 is greater than the inner diameter of the cup mouth of the inner container 5 before flaring and smaller than the inner diameter of the outer container 6. The welding mechanism 3 includes a laser welding gun 31, a guide wheel 32 and a mechanical arm 33, the mechanical arm 33 can be two, and the laser welding gun 31 and the guide wheel 32 correspond to one mechanical arm 33 respectively, so as to drive the laser welding gun 31 and the guide wheel 32 to move towards or away from the cup mouth position where the inner container 5 and the outer container 6 are fitted, the guide wheel 32 is rotationally connected to the driving end of the mechanical arm 33, so as to contact the cup mouth position where the inner container 5 and the outer container 6 are fitted, so as to realize positioning.

[0044] The implementation principle of the thermos cup mouth welding equipment in this application embodiment is as follows: the first motor 12, the second motor 43, the third motor 243, the lifting component 42, the laser welding gun 31, and the robotic arm 33 can be electrically connected to the PLC controller in advance, so that the start and stop of the first motor 12, the second motor 43, the third motor 243, the lifting component 42, the laser welding gun 31, and the robotic arm 33 can be automatically controlled by the PLC controller.

[0045] In actual production, the outer liner 6 is first fitted onto the outside of the inner liner 5 to form a semi-finished cup body 7. Then, the cup body 7 is inserted into the storage space 222 on the turntable 11. At this time, the connecting spring 231 is deformed by the squeezing of the inner wall of the cup body, so that the clamping block 22 abuts against the outer wall of the cup body 7, thereby clamping and fixing the cup body 7. Then, the turntable 11 is driven to proceed according to... Figure 1 The cup body 7 is rotated in the direction indicated by arrow c, so that it stops rotating when it is directly below the flaring mechanism 4. At this time, any of the other placement ports 111 on the turntable 11 will rotate to be directly above the material discharge port 13 in the axial direction. Then, the lifting component 42 drives the conical block 41 to move down and insert it into the mouth of the inner liner 5. As the conical block 41 moves down step by step, the peripheral wall of the mouth of the inner liner 5 is expanded outward to fit against the inner wall of the mouth of the outer liner 6. At this time, the second motor 43 and the third motor 243 are started at the same time to drive the cup body 7 to rotate. At the same time, the mechanical arm 33 puts the guide wheel 32 against the part where the mouth of the inner liner 5 fits against the mouth of the outer liner 6. The mechanical arm 33 moves the laser welding gun 31 to align with the above-mentioned fitting part, and then starts the laser welding gun 31 to weld the fitting part, thus achieving the welding of the peripheral wall of the mouth of the cup.

[0046] During the rotation of the cup 7, the driven gear 2331 drives the driven rack 2332 to move and push the driving ring plate 21 upward. The driving ring plate 21 pushes the driven ring plate 21 located directly above the discharge port 13, so that the driven ring plate 21 pushes the connecting rod 232 to rotate. The connecting rod 232 drives the clamping block 22 to rotate and disengage from the cup 7, so that the cup 7 located directly above the discharge port 13 passes through the discharge port 13 under its own weight and falls onto the conveyor belt 14. Finally, the cup falling from the discharge port 13 is conveyed by the conveyor belt 14.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
