Description

Technical Field

[0001] This invention relates to cup bodies, and more particularly to a manufacturing process for a cup body. Background Technology

[0002] A cup typically consists of a lid and a body, with the lid usually screwed onto the body. During the manufacturing process, the lid and body are produced separately and then screwed together after completion.

[0003] The cup body is manufactured by first making the inner liner and the outer shell separately, and then rolling a threaded ring on the outer shell. After aligning the tops of the inner liner and the outer shell, the two are welded together.

[0004] The cup lid is manufactured by injection molding plastic into a standardized mold to form the corresponding parts, which are then assembled to form the lid. Therefore, the precision and position of the internal threads of the lid are controllable.

[0005] During the actual production process, due to errors in cup rim height, roller rolling, welding, and other factors, the threads on the outer shell vary considerably each time. Specifically, this manifests as errors in thread start height, thread thickness and fullness, and thread diameter. These combined errors will cause the lid to deviate from the intended design direction after it is screwed onto the cup body.

[0006] The above issues are still within acceptable limits for general non-directional lids and cups, and do not affect the smoothness of the screw-on fit or the sealing performance. However, for lids and cups with specific orientations, this problem causes the front of the lid to deviate from the front of the cup after screwing on, resulting in defective products. Currently, these defective products generally account for about 10% of the total number of finished cups. For these 10% of defective products, manual swapping of lids and cups is required for trial fitting. If the trial fitting is successful, the number of defective products can be slightly reduced. If the trial fitting is unsuccessful, the thickness of the sealing silicone ring needs to be further adjusted to individually configure each cup to solve the problem of the lid and cup not aligning properly. This results in a significant increase in manpower, time, and costs, thus requiring improvement. Summary of the Invention

[0007] This invention addresses the shortcomings of existing technologies, such as the inability to precisely screw the cup body onto the lid after the threads are machined, by providing a new manufacturing process for the cup body.

[0008] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0009] A manufacturing process for a cup body includes the following steps:

[0010] S1. Take a debugging inner liner and a debugging threaded ring, align the top of the debugging inner liner with the top of the debugging threaded ring and weld them together to obtain the debugging inner liner assembly.

[0011] S2. Take a real cover and screw the real cover into the threaded ring for debugging.

[0012] S3. A real lid positioning reference is provided on the real lid. The real lid positioning reference on the real lid is projected in the vertical direction to form an inner liner positioning reference on the inner liner for debugging.

[0013] S4. Remove the real cover from the debugging threaded ring, take a simulated cover, the internal thread of the simulated cover is the same as the internal thread of the real cover, screw the simulated cover into the debugging threaded ring, and then project the inner liner positioning reference in the vertical direction to form the simulated cover positioning reference on the simulated cover.

[0014] S5. Remove the simulated cover from the debugging threaded ring, and then project a reference diameter onto the top of the simulated cover with the simulated cover positioning reference as the reference. Set two positioning reference holes symmetrically with the center of the simulated cover as the center on the reference diameter.

[0015] S6. After the simulated cover is inverted, it is placed on the lower mold assembly of the welding mold. The lower mold assembly is provided with two positioning pins. The positioning pins pass through the positioning reference hole and limit the simulated cover.

[0016] S7. Take a real inner liner with the same shape as the inner liner used for debugging and a real threaded ring with the same shape as the threaded ring used for debugging. Align the top of the real inner liner with the top of the real threaded ring and weld them together to obtain a real inner liner assembly. Invert the real inner liner assembly and screw it into place with the simulated lid threaded ring through the real threaded ring.

[0017] S8. Take a real cup body shell, invert the real cup body shell and put it on the real inner liner. Then rotate the real cup body shell so that the front of the real cup body shell is aligned with the positioning reference of the simulated lid. Then align the end of the real cup body shell with the end of the real threaded ring.

[0018] S9. Press the real cup body shell tightly, and then make the simulated lid, the real inner liner component, and the real cup body shell rotate synchronously. While rotating, the connection between the real cup body shell and the real threaded ring is welded by laser to obtain the cup body.

[0019] Step S1 is used to form the inner liner assembly for debugging, so that after being screwed onto the real cover in steps S2 and S3, the positioning reference of the inner liner is formed by the positioning reference of the real cover. The position of the positioning reference of the real cover on the real cover indicates the front of the real cover.

[0020] Step S4 further forms a simulated lid positioning reference on the simulated lid using the inner liner positioning reference. Since the threaded surface of the simulated lid is consistent with the real lid, the simulated lid will participate in the manufacturing process of the cup body as a replica of the real lid in the subsequent manufacturing process, thereby forming a unified manufacturing standard.

[0021] Step S5 is used to form two positioning reference holes on the simulated lid. Since these two positioning reference holes are gradually aligned with the positioning reference and reference diameter of the simulated lid, as long as the simulated lid is positioned through these two positioning reference holes, the front of the simulated lid, which is also the front of the real lid, can be positioned, thus providing a reference for the subsequent positioning of the front of the cup body.

[0022] In step S6, two positioning pins are set on the lower mold assembly, thereby limiting the simulated lid through the positioning pins and positioning reference holes, thus fixing the position of the simulated lid in the lower mold assembly. In the subsequent welding process of each cup body, the front of the cup body can be aligned with the simulated lid, making the alignment more convenient and accurate.

[0023] Step S7 is the welding and screwing process of the real inner liner component. Since the real inner liner component has the same shape as the inner liner component used for debugging, it can be directly screwed into the simulated lid after the real inner liner component is welded, thus forming a unified standard in the steps before and after manufacturing. In addition, since there is no real cup body shell involved at this time, the real thread ring on the real inner liner component only needs to be screwed into the simulated lid thread, without having to worry about the position of the cup body after the real thread ring and the simulated lid thread are in place, thus avoiding the problem of inconsistent thread position caused by various factors during the manufacturing process of the real thread ring.

[0024] Step S8 is the alignment step of the actual cup body shell. Since a unified alignment standard has been established in the early stage, in this step, the actual cup body shell only needs to rotate its front side to the same direction as the positioning reference of the simulated lid. After the laser welding process in step S9, the front sides of the cup body and the actual lid can be consistent after they are screwed into place.

[0025] This invention, through the above steps, divides the cup body into three parts: the actual outer shell, the actual threaded ring, and the actual inner liner. This separates the manufacturing processes of the actual outer shell and the actual threaded ring, eliminating the mutual influence between the frontal orientation of the actual outer shell and the manufacturing errors of the actual threaded ring. Next, in the manufacturing process, the actual threaded ring and the actual inner liner are first assembled to form the actual inner liner assembly. Because the actual inner liner is enclosed by the actual outer shell during use, it lacks directionality. Therefore, the assembled actual inner liner assembly itself also lacks directionality, and the combination of the two does not cause any other adverse effects. To solve the problems of frontal orientation alignment of the actual outer shell and manufacturing errors of the actual threaded ring, this invention projects the positioning reference of the actual lid onto the inner liner to form an inner liner positioning reference. Then, the inner liner... The positioning reference is projected onto the simulated lid to form the simulated lid positioning reference. Finally, the reference diameter is formed by projecting the simulated lid positioning reference, and two positioning reference holes are obtained through the reference diameter to obtain a unified standard for comparison. This allows the front face of the real lid to be projected onto the simulated lid positioning reference. In addition, the simulated lid is limited to the lower mold assembly by the two positioning reference holes and two positioning pins, so that the orientation of the simulated lid remains unchanged after it is placed on the lower mold assembly. Therefore, during the later manufacturing process, when the operator welds the real cup body shell to the real threaded ring, the operator can directly use the simulated lid positioning reference to locate the front orientation of the real cup body shell, thereby bypassing the influence of manufacturing errors of the real threaded ring. This greatly improves the matching degree of the front orientation of the real cup body shell and the real lid after screwing them together, and improves the product qualification rate.

[0026] Preferably, in the above-described manufacturing process for a cup body, step S3 further includes the following step:

[0027] S31. Take a debugging shell, put the debugging shell over the debugging inner liner and align the end of the debugging shell with the end of the debugging threaded ring, and then rotate the debugging shell so that the front of the debugging shell is aligned with the positioning reference of the real cover.

[0028] S32. Project the actual cover positioning reference on the actual cover in the vertical direction to form a housing positioning reference on the debugging housing;

[0029] Step S7 further includes the following step:

[0030] S71. After inverting the debugging shell, place it on the real inner liner, and then rotate the debugging shell so that the shell positioning reference on the debugging shell is aligned with the simulated cover positioning reference.

[0031] S72. The debugging housing has feature points. An optical positioning device is used and emits light to align with the feature points on the debugging housing.

[0032] Step S8 is replaced by:

[0033] Take a real cup shell with the same shape as the outer shell used for debugging, invert the real cup shell and put it on the real inner liner, then rotate the real cup shell so that the feature points on the real cup shell are aligned with the light emitted by the optical positioning device, and then align the end of the real cup shell with the end of the real threaded ring.

[0034] Because the positioning reference of the simulated lid may be partially obscured by various components of the lower mold assembly after the simulated lid is placed on it, it is inconvenient for the operator to align the front of the actual cup body. However, the setup of the debugging shell allows the positioning reference on the debugging shell to align with the positioning reference of the simulated lid. This enables the light emitted by the debugging shell and the optical positioning device to work together to find a feature point on the debugging shell. Since the shape of the debugging shell is consistent with the actual cup body, when aligning the front of the actual cup body with the positioning reference of the simulated lid on the lower mold assembly, the operator no longer needs to painstakingly search for the positioning reference on the simulated lid. Instead, they can find the feature point formed by the interplay of light emitted from the optical positioning device and the actual cup body, thereby further improving the accuracy and efficiency of alignment.

[0035] Preferably, in the manufacturing process of the cup body described above, the optical positioning device is a laser positioning device.

[0036] The laser positioning device emits a more concentrated laser beam, resulting in more accurate positioning.

[0037] Preferably, in the manufacturing process of the cup body described above, the feature point is the edge of the groove or the edge of the boss.

[0038] Using the groove or protrusion edge on the actual cup body as a feature point provides a more distinct identification, which can further improve the accuracy and efficiency of alignment.

[0039] Preferably, in the above-described manufacturing process for a cup body, the welding mold further includes a mold support, an upper mold assembly, a control assembly, and a laser welding assembly. The upper mold assembly includes a pressing cylinder and a clamping die head. The pressing cylinder is disposed on the upper part of the mold support, and the clamping die head is rotatably connected to the pressing cylinder. The lower mold assembly includes an upper lifting cylinder, a rotating rod assembly, a rotary drive assembly, and a lid positioning assembly. The upper lifting cylinder and the rotary drive assembly are respectively disposed on the lower part of the mold support. The lower end of the rotating rod assembly is rotatably connected to the upper lifting cylinder, and the upper end of the rotating rod assembly is connected to the lid positioning assembly. The rotary drive assembly is connected to the rotating rod assembly, and the lid positioning assembly is rotatably connected to the mold support. The lid positioning assembly is provided with a lid receiving cavity, and the positioning post is disposed within the lid receiving cavity.

[0040] In step S6, the simulated lid is placed upside down into the lid receiving cavity of the lid positioning assembly on the lower mold assembly, and the positioning post passes through the positioning reference hole and limits the simulated lid.

[0041] In step S9, the pressing cylinder drives the pressing die head to move down and press the real cup body shell. Then, the rotation drive assembly drives the rotating rod assembly to rotate, thereby driving the lid positioning assembly, the simulated lid, the real inner liner assembly, and the real cup body shell to rotate synchronously. At the same time, the laser emitted by the laser welding assembly welds the joint between the real cup body shell and the real threaded ring to obtain the cup body.

[0042] It also includes step S10: the pressing cylinder drives the pressing die head to move up, and then the upper cylinder pushes the simulated lid out upward through the rotating rod assembly and the lid positioning assembly, thereby removing the cup body from the simulated lid.

[0043] The mold support supports all components, the upper mold assembly presses the real cup shell during welding, the control assembly controls the operation of each component, the rotation drive assembly drives the rotating rod assembly to rotate, thereby causing the lid positioning assembly, the real inner liner assembly, and the real cup shell to rotate during welding, and the laser welding assembly welds the joint between the real cup shell and the real threaded ring. The lid positioning assembly can accommodate the simulated lid and limit its position, and can also work with the top cylinder to push the simulated lid out after welding, making it easier for the operator to remove the welded cup.

[0044] Preferably, in the above-described manufacturing process for a cup body, the lid positioning assembly includes a mounting base, a movable base, and an ejector block. The mounting base is rotatably connected to a mold support, and the mounting base has a mounting base receiving cavity. The movable base is placed in the mounting base receiving cavity, the lid receiving cavity and the positioning post are disposed on the movable base, the ejector block is located in the lid receiving cavity, and the positioning post passes through the ejector block. The upper end of the rotating rod assembly passes through the mounting base and the movable base and is connected to the ejector block.

[0045] The mounting base is used to install the movable seat and the ejector block. The movable seat is placed inside the mounting base, which improves the flexibility of mold changing and can better adapt to the placement requirements of different simulated covers. The ejector block and the rotating rod assembly work together to eject the simulated cover after welding, which improves the efficiency of picking and placing.

[0046] As a preferred embodiment, in the manufacturing process of the cup body described above, an ejector spring is also fitted on the positioning post, one end of the ejector spring abuts against the inner wall of the lid receiving cavity, and the other end of the ejector spring abuts against the ejector block.

[0047] The ejection spring further enhances the smoothness of the simulated lid ejection, thereby improving ejection efficiency.

[0048] As a preferred embodiment, in the manufacturing process of the cup body described above, a resetting reinforcing rib is also provided between the mounting base and the movable base.

[0049] The reset reinforcing bar can be used to support the movable seat, so that the position height of the real threaded ring supported by the movable seat after the real threaded ring is screwed into the simulated lid remains consistent each time, thereby improving the concentricity between the real threaded ring and the real cup body shell during mass production.

[0050] Preferably, the manufacturing process of the cup body described above further includes a limiting drive cylinder and an intermediate docking seat. The limiting drive cylinder is disposed on the mold support, the intermediate docking seat is connected to the limiting drive cylinder, the mounting seat is rotatably connected to the intermediate docking seat, and at least two limiting posts are evenly disposed on the intermediate docking seat, the upper end of the limiting post corresponding to the mold support.

[0051] In step S6, before the simulated lid is placed upside down into the lid receiving cavity of the lid positioning component on the lower mold assembly, the limiting drive cylinder first drives the mounting seat to move upward through the intermediate docking seat until the upper end of the limiting post on the intermediate docking seat abuts against the mold support and stops. At the same time, the upper push cylinder also moves the ejector block upward synchronously through the rotating rod assembly.

[0052] In step S10, the downward pressing cylinder drives the pressing die head to move upward, and then the limiting driving cylinder first drives the mounting seat to move downward through the intermediate docking seat, so that the ejector block, the simulated lid, and the cup body on the mounting seat are initially ejected under the action of the rotating rod assembly; then the upward pressing cylinder drives the rotating rod assembly to move upward and ejects the ejector block, the simulated lid, and the cup body again. At this time, the cup body and the simulated lid are removed from the ejector block together, and then the cup body is removed from the simulated lid.

[0053] The setting of limit drive cylinder, intermediate docking seat and limit post can, on the one hand, make the cover positioning component move up and down, which is convenient for simulating the placement and ejection of the cover. On the other hand, it can make the cover positioning component stop at the same position every time it moves upward, thereby improving the accuracy of welding. Furthermore, the limit post can also be leveled by pressing against the mold support, thereby further improving the product quality. Attached Figure Description
