Description

Technical Field

[0001] This utility model relates to the field of cup lid latching machine technology, and in particular to a flexible latching machine that can adapt to cup lids of different materials. Background Technology

[0002] In the automated assembly production of everyday cup lids, the pin structure is a crucial component for opening, sealing, or positioning the lid, and its assembly quality directly affects the sealing performance and lifespan of the cup. Most existing pin-insertion machines rely on a fixed mold structure to clamp and position the cup lid, and use cylinders or motors to drive the pin insertion.

[0003] However, due to significant differences in size, thickness, structural rigidity, and materials such as ABS plastic, food-grade silicone, and stainless steel coated with rubber among different types of water cup lids, traditional pin-fitting machines usually require changing the clamps or adjusting the positioning structure to adapt to different water cup lid products. This is cumbersome to operate, has low switching efficiency, and is difficult to meet the needs of flexible production in a multi-variety, small-batch production mode. Utility Model Content

[0004] Based on this, it is necessary to address the significant differences in size, thickness, structural rigidity, and materials (such as ABS plastic, food-grade silicone, and stainless steel coated) of different types of cup lids. Traditional pin-fitting machines typically require changing clamps or adjusting positioning structures to adapt to different cup lid products, resulting in cumbersome operation, low switching efficiency, and difficulty in meeting the flexible production needs of multi-variety, small-batch production models. Therefore, a flexible pin-fitting machine adaptable to cup lids of different materials is provided, comprising: a base, with a support frame fixedly installed on the top of the base, and a pin-fitting machine fixedly installed on one side of the support frame; a pin-fitting adaptation mechanism, used to adapt and fix pins to cup lids of different materials and sizes, the pin-fitting adaptation mechanism being disposed on the top of the base; wherein, the pin-fitting adaptation mechanism includes a fixing frame disposed on the top of the base, an adaptation component disposed on one side of the fixing frame, an alignment component disposed on the outer side of the fixing frame, and the fixing frame being located at the bottom of the pin-fitting machine.

Multiple piston plates are slidably connected to the outer side of the connecting plate. An air pump is fixedly installed on one side of the mounting bracket. The output end of the air pump extends into the interior of the connecting plate and communicates with one side of the multiple piston plates.

[0006] Each of the piston plates has a contact plate on its opposite side, and all of the contact plates are configured in an arc shape.

[0008] The rubber strips are all configured in a semi-circular shape and are equidistantly distributed.

[0009] A connecting plate is fixedly installed on the side of the contact plate near the adjacent piston plate. The connecting plate is slidably connected to the piston plate. An induction pressure plate is fixedly installed inside the piston plate. Springs are provided on both sides of the induction pressure plate.

[0028] The following is combined with Figures 1-5 This invention describes a flexible pin insertion machine that can adapt to water cup lids made of different materials.

[0029] In one embodiment, a flexible pin-fitting machine adaptable to cup lids of different materials includes: a base 100, a support frame 200 fixedly mounted on the top of the base 100, and a pin-fitting machine 210 fixedly mounted on one side of the support frame 200; a pin-fitting adaptation mechanism 300, which is disposed on the top of the base 100 for adapting and fixing pins to cup lids of different materials and sizes; wherein, the pin-fitting adaptation mechanism 300 includes a fixing frame 310 disposed on the top of the base 100, an adaptation component 320 disposed on one side of the fixing frame 310, an alignment component 330 disposed on the outer side of the fixing frame 310, and the fixing frame 310 is located at the bottom of the pin-fitting machine 210.

[0030] In this embodiment, the water cup lid can be placed on one side of the fixing frame 310 during use. The adapter component 320 adapts and positions water cup lids of different materials and sizes. It can adaptively clamp the water cup lid according to the differences in outer diameter, edge shape and rigidity, avoiding slippage, displacement or pinching caused by differences in material hardness or size. This achieves stable fixing of various types of water cup lids. The alignment component 330 is set on the outside of the fixing frame 310. It can pass through before the pin action to automatically align the pin hole, avoiding manual adjustment or insertion failure caused by slight hole deviation, effectively improving the success rate and accuracy of the pin action.

[0031] It should be noted that the existing cup lid pinning machine 210 typically includes: a base 100 for supporting the entire machine structure, a pinning actuator such as an electric pinning device or a pneumatic punch for providing pin driving force, a support platform for placing cup lids, and a manual or semi-automatic auxiliary alignment mechanism for positioning the cup lid pin holes. The adapter component 320 is located on one side of the fixed frame 310 and is used for adaptive clamping of cup lids of different materials and sizes. This clamping process is completed before the pinning machine 210 is started, and the clamping state does not interfere with the downward pressing path of the pin head. The alignment component 330 is located on the outside of the fixed frame 310, and its action flow is time-separated from the pinning action—that is, the positioning calibration is completed before the pinning action is executed, so that it will not interfere with or resist the pinning machine 210 during the pinning process.

[0032] like Figure 2 , Figure 3 and Figure 4 As shown, the adapter component 320 includes a connecting plate 321 fixedly installed on one side of the mounting bracket 310. Multiple piston plates 322 are slidably connected to the outer side of the connecting plate 321. An air pump 323 is fixedly installed on one side of the mounting bracket 310. The output end of the air pump 323 extends into the interior of the connecting plate 321 and communicates with one side of the multiple piston plates 322.

[0033] In this embodiment, multiple piston plates 322 are synchronously driven by the air pump 323 to slide along the radial direction of the connecting plate 321, which can achieve adaptive clamping of water cup lids of different sizes. It is especially suitable for common plastic lids, metal lids or composite material lids, which are difficult to clamp uniformly due to differences in outer diameter, tolerance or edge rigidity. The piston plates 322 can achieve flexible and controllable clamping force through air pressure regulation, effectively avoiding the risk of brittle lid breaking or deforming due to excessive clamping force, while avoiding water cup lid sliding or displacement caused by insufficient clamping force, thereby ensuring the stability and accuracy of subsequent pin action.

[0034] Each of the multiple piston plates 322 has a contact plate 324 on the side that is far apart from each other, and the multiple contact plates 324 are all set in an arc shape.

[0035] In this embodiment, the contact plate 324 can make larger contact with the inner ring wall of the cup lid, which not only improves the uniformity of force during clamping, but also effectively adapts to cup lid structures with different inner diameter curvatures, preventing deformation, slippage, or damage to the cup lid due to excessive local force. The arc-shaped contact surface enhances clamping stability and further improves the adaptability of the adapter component 320 to cup lids of different materials and sizes.

[0036] The surface of the contact plate 324 is provided with a groove, and multiple rubber strips 325 are fixedly installed on the surface of the groove of the contact plate 324.

[0037] In this embodiment, by providing grooves on the surface of the contact plate 324 and fixing multiple rubber strips 325 within the grooves, the contact plate 324 has stronger cushioning and anti-slip capabilities when clamping the cup lid. The rubber strips 325 have good flexibility and friction properties, which can enhance the clamping stability without damaging the surface of the cup lid. They are particularly suitable for cup lids made of thin-walled, fragile, or smooth materials such as plastic and glass, effectively preventing slippage, displacement, or deformation during the clamping process.

[0038] Multiple rubber strips 325 are all set in a semi-circular shape, and multiple rubber strips 325 are equidistantly distributed.

[0039] In this embodiment, by setting multiple rubber strips 325 to a semi-circular shape, a more uniform contact surface can be provided when in contact with the inner wall of the cup lid, improving the coverage and force balance during clamping, and avoiding damage to the cup lid caused by localized concentrated force.

[0040] A connecting plate 326 is fixedly installed on the side of the contact plate 324 near the adjacent piston plate 322. The connecting plate 326 is slidably connected to the piston plate 322. An induction pressure plate 327 is fixedly installed inside the piston plate 322. Springs 328 are provided on both sides of the induction pressure plate 327. One side of the induction pressure plate 327 is in contact with the connecting plate 326.

[0041] In this embodiment, by setting a sensing pressure plate 327 inside the piston plate 322 and arranging springs 328 on both sides thereon, real-time sensing feedback of the force state of the contact plate 324 during the clamping of the cup lid can be realized. When the contact plate 324 contacts the inner wall of the cup lid and reaches the preset clamping force, the sensing pressure plate 327 is displaced by the force and buffered and fed back by the deformation of the spring 328, thereby judging whether the clamping state is stable. The sliding connection between the connecting plate 326 and the piston plate 322 enables the displacement of the sensing pressure plate 327 to be accurately transmitted to the contact plate 324, realizing the detection of whether the cup lid is firmly fixed before the pin is inserted, which helps to avoid slippage, deformation or damage caused by insufficient or excessive clamping.

[0042] It should be noted that the sensing plate 327 is an elastic detection structure located in the center of the piston plate 322. Its material can be stainless steel springs, alloy springs, or conductive rubber pads, etc., which possess deformation feedback capabilities and exhibit good resilience and fatigue resistance. When subjected to axial pressure from the connecting plate 326, the sensing plate 327 undergoes a slight deformation, thereby driving the internal sensing unit or linking with the displacement monitoring device to determine whether the contact plate 324 has effectively adhered to and clamped the inner wall of the cup lid. Springs 328 are provided on both sides of the sensing plate 327 to provide a rebound force after the clamping action is completed, preventing the sensing structure from malfunctioning or causing a decrease in accuracy due to prolonged pressure.

[0043] like Figure 2 and Figure 5 As shown, the alignment assembly 330 includes an electric slide rail 331 disposed on the outside of the fixing frame 310. The electric slide rail 331 is fixedly installed on the top of the base 100, and the output end of the electric slide rail 331 is fixedly connected to one side of the fixing frame 310.

[0044] In this embodiment, the electric slide rail 331 can drive the entire fixed frame 310 to make precise lateral fine adjustments under the action of control commands, so that the position of the cup lid relative to the pin machine 210 can be automatically aligned.

[0045] Multiple laser calibrators 332 are fixedly installed at the bottom of the pin-mounting machine 210, and all of the laser calibrators 332 are located on the top of the connecting plate 321.

[0046] In this embodiment, by fixing multiple laser calibrators 332 at the bottom of the pin-fitting machine 210 and arranging them in the top area of ​​the connecting plate 321, the actual position of the cup lid pin hole can be accurately detected in non-contact manner before the pin is inserted. The laser calibrator 332 can emit a high-precision laser beam to scan and position the cup lid pin hole in real time and feed back the deviation information to the control system, which is used to drive the electric slide rail 331 to adjust the micro-displacement of the fixing frame 310, thereby achieving high-precision alignment between the pin hole and the pin-fitting machine 210.

[0047] It should be noted that the laser calibrator 332 is a non-contact, high-precision positioning sensor device. Its main function is to scan and position the cup lid's pin hole in real time before the pin is inserted. The laser calibrator 332 emits a fine laser beam to illuminate the target area and, by combining the recovery and calculation of the reflected light, obtains the center coordinates, hole diameter, and offset of the pin hole relative to the pin-inserting mechanism 210. This device typically integrates a signal processing module, which can transmit the positioning data to the control system in real time, enabling automated adjustment of the position of the pin-inserting mechanism 210 or the cup lid clamping part to ensure precise alignment between the pin's movement and the hole position.

[0048] Working Principle: During use, the operator places the cup lid to be inserted on one side of the fixing frame 310. Under the action of the control signal, the adapter component 320 starts the air pump 323, driving multiple circumferentially arranged piston plates 322 to slide towards the center, thereby causing the contact plate 324 at its front end to contact and adhere to the inner ring wall of the cup lid. The rubber strip 325 on the contact plate 324 provides flexible cushioning and anti-slip force to prevent the cup lid from slipping or being damaged due to material differences or dimensional tolerances. When the clamping force reaches the preset value, the built-in sensing pressure plate 327 deforms due to the force, and the displacement signal is fed back through the spring 328 to determine that the clamping action has been completed and stabilized. Subsequently, the alignment component 330 is activated, controlling the electric slide rail 331 to drive the fixing frame 310 to make fine adjustments in the lateral direction, so that the cup lid's insertion hole is roughly aligned with the insertion position of the insertion machine 210. At this time, multiple laser calibrators 332 on the bottom of the pin-inserting machine 210 are simultaneously activated to perform non-contact scanning of the pin holes on the surface of the cup lid, obtaining the precise coordinates of the hole positions. When a slight deviation in the pin hole is detected, the system automatically drives the electric slide rail 331 to perform micro-position correction based on the laser calibration data until the hole position and the pin tip are precisely aligned. After completing the above steps, the pin-inserting machine 210 initiates the pin-inserting action, precisely pressing the pin into the hole of the cup lid, completing the pin-inserting process. The entire process achieves adaptive clamping and high-precision alignment for cup lids of various materials and sizes.

[0049] It should be noted that the pin-inserting machine, induction pressing plate, laser calibrator, and electric slide rail mentioned above are all devices with relatively mature existing technologies. The specific model can be selected according to actual needs. At the same time, the pin-inserting machine, induction pressing plate, laser calibrator, and electric slide rail can be powered by the built-in power supply or by the mains power. The specific power supply method should be selected according to the situation, and will not be elaborated here.

[0050] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0051] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
