Description

Technical Field

[0001] This application relates to the field of bottle washing machine technology, and in particular to a clamping structure and a bottle washing machine. Background Technology

[0002] In the packaging process of food and medicine, the inner and outer surfaces of the bottles must first be cleaned to ensure that their cleanliness meets production standards. A clamping mechanism holds and fixes the bottle during this process, keeping it stable and ensuring that the cleaning medium can fully contact the inner and outer surfaces of the bottle, achieving a thorough cleaning effect without any blind spots.

[0003] In the process of picking up or fixing vials, the clamping structure typically employs a single-clamp gripper. This structure consists of two clamping arms: one fixed clamping arm and the other a rotatable swinging clamping arm. The clamping force of the clamping arm mainly comes from the spring, while the opening force depends on the force exerted by the opening cam on the swinging clamping arm.

[0004] However, the aforementioned grippers may push the bottle away from its original position when gripping it, resulting in lower gripping accuracy. Utility Model Content

[0005] This application provides a clamping structure and a bottle washing machine to improve the accuracy of bottle clamping.

[0006] In a first aspect, embodiments of this application provide a clamping structure, including:

[0007] Mounting base;

[0008] A clamping assembly includes a main clamping arm, a slave clamping arm, and a linkage member. The main clamping arm and the slave clamping arm are rotatably mounted on the mounting base. The linkage member is mounted on the main clamping arm and connected to the slave clamping arm. The linkage member is configured to synchronously drive the slave clamping arm to rotate in the opposite direction when the main clamping arm rotates, so that the main clamping arm and the slave clamping arm cooperate to clamp the object to be clamped.

[0009] A drive assembly is disposed on the mounting base, the drive assembly is connected to the main clamping arm, and the drive assembly is used to drive the main clamping arm to rotate.

[0010] In one possible implementation, the linkage includes a first tooth and a second tooth, the first tooth being disposed on the main clamping arm and the second tooth being disposed on the slave clamping arm, the first tooth and the second tooth engaging.

[0011] In one possible implementation, both the main clamping arm and the slave clamping arm are provided with chucks, and the chucks are provided with limit grooves for limiting the object to be clamped.

[0012] In one possible implementation, the clamp is a polyetheretherketone (PEEK) component.

[0013] In one possible implementation, the drive assembly includes a drive rod, a connecting shaft, and a drive member. The connecting shaft is connected to the main clamping arm, one end of the drive rod is connected to the connecting shaft, and the drive member is connected to the drive rod. The drive member is used to drive the drive rod to swing, thereby rotating the connecting shaft.

[0014] In one possible implementation, the drive element includes a cam, a connecting rod, and a follower bearing. The connecting rod is disposed on the drive rod, and the follower bearing is sleeved on the connecting rod. The cam abuts against the follower bearing to push the drive rod to swing.

[0015] In one possible implementation, an elastic element is provided on the main clamping arm, the elastic element being located between the main clamping arm and the slave clamping arm, the elastic element being used to drive the clamps on the main clamping arm and the slave clamping arm to move closer to each other.

[0016] In one possible implementation, a guide rod is provided on the main clamping arm, and the elastic element is sleeved on the guide rod.

[0017] In one possible implementation, the mounting base includes an upper body and a lower body, the upper body being connected to the lower body, and the clamping assembly being located between the upper body and the lower body and connected to the upper body and the lower body respectively.

[0018] Secondly, embodiments of this application provide a bottle washing machine, including a bottle washing machine body and a clamping structure disposed on the bottle washing machine body.

[0019] This application provides a clamping structure and a bottle washing machine. The clamping structure rotatably mounts a main clamping arm and a driven clamping arm on a mounting base. A linkage connects the main and driven clamping arms, so that when the main clamping arm rotates, it synchronously drives the driven clamping arm to rotate in the opposite direction. The main and driven clamping arms cooperate to clamp the part to be clamped. A drive assembly drives the main clamping arm to rotate, thus achieving the clamping of the part. The synchronous counter-rotation of the main and driven clamping arms effectively reduces the pushing caused by the gripper's movement when clamping the part, thereby improving the clamping accuracy and stability.

These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0034] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0035] In the bottle cleaning process for food and pharmaceutical packaging, single-clamp grippers often exhibit low precision and are prone to deviation when gripping bottles. This structure consists of a fixed clamping arm and a rotating, opening / closing swinging clamping arm. The asymmetrical design of the fixed and swinging arms makes it difficult for the grippers to achieve precise centering when gripping bottles. During movement, the swinging arm is prone to deviating from its ideal position due to mechanical errors, wear, or vibration, causing the grippers to fail to accurately center the bottle. Secondly, the clamping force relies on a spring, and the spring's elastic coefficient and fatigue level are affected by various factors, such as spring aging due to long-term use and temperature changes, making the clamping force unstable and unable to be evenly applied to the bottle. Furthermore, the opening force is exerted by the opening cam on the swinging clamping arm. This structure is susceptible to mechanical vibration and cam wear during movement, leading to inaccurate or unstable opening actions. These structural defects interact, causing the grippers to wobble or loosen when gripping bottles, ultimately resulting in instability during bottle handling and even bottle dropping.

[0036] This application provides a clamping structure and a bottle washing machine. The clamping structure rotatably mounts a main clamping arm and a driven clamping arm on a mounting base. A linkage connects the main and driven clamping arms, so that when the main clamping arm rotates, it synchronously drives the driven clamping arm to rotate in the opposite direction. The main and driven clamping arms cooperate to clamp the part to be clamped. A drive assembly drives the main clamping arm to rotate, thus achieving the clamping of the part. The synchronous counter-rotation of the main and driven clamping arms effectively reduces the pushing caused by the gripper's movement when clamping the part, thereby improving the clamping accuracy and stability.

[0037] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0038] This application provides a clamping structure, referring to... Figure 1 , Figure 2 and Figure 3 The clamping structure includes a mounting base 100, a clamping assembly 200, and a drive assembly 300.

[0039] The clamping assembly 200 includes a main clamping arm 210, a slave clamping arm 220, and a linkage 230. Both the main clamping arm 210 and the slave clamping arm 220 are rotatably mounted on the mounting base 100. The linkage 230 is mounted on the main clamping arm 210 and connected to the slave clamping arm 220. The linkage 230 is configured to synchronously drive the slave clamping arm 220 to rotate in the opposite direction when the main clamping arm 210 rotates, so that the main clamping arm 210 and the slave clamping arm 220 cooperate to clamp the object to be clamped. The drive assembly 300 is mounted on the mounting base 100 and connected to the main clamping arm 210. The drive assembly 300 is used to drive the main clamping arm 210 to rotate.

[0040] The linkage 230 enables synchronous counter-rotation of the main gripper arm 210 and the slave gripper arm 220, effectively reducing the pushing caused by the gripper's movement when clamping the item to be held, thereby improving the clamping accuracy and stability. It not only accurately clamps the item to be held but also maintains high reliability during the high-speed operation of the bottle washing machine, effectively avoiding bottle drops or positional deviations caused by unstable clamping.

[0041] In the embodiments of this application, the object to be clamped is a bottle. In other embodiments, the object to be clamped may be other articles.

[0042] In one possible implementation, refer to Figure 1 and Figure 2 The mounting base 100 includes an upper base 110 and a lower base 120. The upper base 110 is connected to the lower base 120. The clamping assembly 200 is located between the upper base 110 and the lower base 120 and is connected to the upper base 110 and the lower base 120 respectively.

[0043] For example, the upper seat 110 includes a flat plate portion and a boss portion, which are integrally formed. The boss portion is disposed at the edge of the flat plate portion, so that the upper seat 110 is L-shaped. The lower seat 120 has a flat plate structure. A mounting groove is formed between the upper seat 110 and the lower seat 120. The clamping assembly 200 is installed in the mounting groove and partially extends out of the mounting groove to clamp the part to be clamped.

[0044] For example, the upper seat 110 is bolted to the lower seat 120.

[0045] In one possible implementation, refer to Figure 2 and Figure 3 The linkage 230 includes a first tooth 231 and a second tooth 232. The first tooth 231 is disposed on the main clamping arm 210, and the second tooth 232 is disposed on the slave clamping arm 220. The first tooth 231 and the second tooth 232 mesh with each other.

[0046] The precise linkage between the main gripper arm 210 and the driven gripper arm 220 is achieved through the meshing of the first tooth 231 and the second tooth 232. When the main gripper arm 210 rotates, the first tooth 231 drives the second tooth 232 to rotate in the opposite direction, thereby ensuring that the driven gripper arm 220 moves synchronously and in the opposite direction to the main gripper arm 210. This not only improves the accuracy and stability of gripping, but also reduces the shaking and positional deviation of the gripped part during the gripping process through precise gear meshing, significantly improving the reliability and gripping efficiency of the grippers in the bottle washing machine.

[0047] In some examples, the first tooth 231 and the second tooth 232 can be a complete gear. The axis of rotation of the first tooth 231 coincides with the axis of rotation of the main clamping arm 210, and the axis of rotation of the second tooth 232 coincides with the axis of rotation of the secondary clamping arm 220.

[0048] In other examples, the first tooth 231 and the second tooth 232 can also be partial gears, which are portions of a gear cut radially while retaining some teeth. By using partial gears, the overall weight can be effectively reduced, and the required installation space can be reduced.

[0049] For example, the main clamping arm 210 and the slave clamping arm 220 are arranged symmetrically.

[0050] In one possible implementation, refer to Figure 3 and Figure 4 Both the main clamping arm 210 and the slave clamping arm 220 are provided with chucks 240, and each chuck 240 is provided with a limiting groove 241, which is used to limit the part to be clamped.

[0051] A limiting groove 241 is provided on the chuck 240. The limiting groove 241 can limit the position of the part to be clamped, ensuring that it will not slip or deviate during the clamping process. In this way, the gripper can hold the part to be clamped more stably, improving the clamping accuracy and reliability. This not only reduces the risk of bottles falling due to unstable clamping, but also improves the overall operating efficiency and product quality of the bottle washing machine.

[0052] For example, the limiting groove 241 can be a V-shaped groove.

[0053] For example, the chuck 240 has insertion slots on both sides, and each end of the main clamping arm 210 and the driven clamping arm 220 has two insertion rods. The insertion rods are inserted into the two insertion slots. The chuck 240 is also provided with connecting bolts, which pass through the chuck 240 and are threadedly connected to the main clamping arm 210 or the driven clamping arm 220. By inserting the insertion rods into the insertion slots, the chuck 240 is limited and initially fixed, and then fixed by the connecting bolts to improve the stability of the chuck 240.

[0054] In one possible implementation, the chuck 240 is a polyetheretherketone (PEEK) component.

[0055] Polyether ether ketone (PEEK) components possess excellent thermal stability and mechanical properties. This effectively extends the service life of the chuck 240 and prevents metal parts from scratching the workpiece during clamping.

[0056] In one possible implementation, refer to Figure 2 , Figure 7 and Figure 8 The drive assembly 300 includes a drive rod 310, a connecting shaft 320, and a drive member 330. The connecting shaft 320 is connected to the main clamping arm 210. One end of the drive rod 310 is connected to the connecting shaft 320. The drive member 330 is connected to the drive rod 310 and is used to drive the drive rod 310 to swing so as to rotate the connecting shaft 320.

[0057] For example, the main clamping arm 210 has a connecting hole in the middle, and the connecting shaft 320 is inserted into the connecting hole. Flange bearings 321 are sleeved on both ends of the connecting shaft 320 so that the two ends of the connecting shaft 320 are rotatably connected to the upper seat 110 and the lower seat 120 respectively, and the main clamping arm 210 uses the connecting shaft 320 as the rotating axis.

[0058] For example, the driven arm 220 is configured the same as the main arm 210, and is also provided with a connecting hole. It is rotatably connected between the upper body 110 and the lower body 120 via a connecting shaft 320. The rotation axes of the driven arm and the main arm are parallel.

[0059] For example, the connecting shaft 320 is fixedly connected to one end of the driving rod 310 and is perpendicular to the length direction of the driving rod 310. By rotating the driving rod 310, the connecting shaft 320 can be driven to rotate, thereby driving the driving arm to rotate.

[0060] For example, to improve clamping efficiency, multiple clamping assemblies 200 are mounted on the same mounting base 100. In the example of this application, six clamping assemblies 200 are provided on the same mounting base 100.

[0061] In one possible implementation, refer to Figure 2 , Figure 5 and Figure 6 The driving component 330 includes a cam 331, a connecting rod 332, and a follower bearing 333. The connecting rod 332 is mounted on the driving rod 310, and the follower bearing 333 is sleeved on the connecting rod 332. The cam 331 abuts against the follower bearing 333 to push the driving rod 310 to swing.

[0062] For example, cam 331 can be rotatably connected to mounting base 100 or rotatably mounted on the frame of bottle washing machine. Cam 331 is connected to a motor so that cam 331 can be driven to rotate by the motor (not shown in the figure).

[0063] For example, the connecting rod 332 is fixed to the end of the active rod 310 away from the connecting shaft 320, and the connecting rod 332 is parallel to the connecting shaft 320.

[0064] In the embodiments of this application, two follower bearings 333 are provided, and both follower bearings 333 are sleeved on the connecting rod 332 to increase the contact area with the cam 331.

[0065] For example, in order to improve efficiency and reduce the use of motors, multiple clamping assemblies 200 on the mounting base 100 share the same cam 331.

[0066] For example, the connecting rod 332 can be a bolt, and two washers 334 are fitted on the connecting rod 332. The washers 334 are located on both sides of the follower bearing 333 to reduce loosening and friction damage of the connecting rod 332 during rotation.

[0067] The precise driving of the drive rod 310 is achieved through the coordinated action of the cam 331, connecting rod 332, and follower bearing 333. The connecting rod 332 is mounted on the drive rod 310, and the follower bearing 333 is sleeved on the connecting rod 332, ensuring smooth movement and low friction. When the cam 331 rotates, it smoothly pushes the drive rod 310 to swing through contact with the follower bearing 333. The rotation of the cam 331 can precisely control the swing angle of the drive rod 310, thereby achieving precise control of the clamping actions of the main clamping arm 210 and the slave clamping arm 220.

[0068] In one possible implementation, an elastic element 250 is provided on the main clamping arm 210, the elastic element 250 is located between the main clamping arm 210 and the slave clamping arm 220, and the elastic element 250 is used to drive the clamps 240 on the main clamping arm 210 and the slave clamping arm 220 to move closer to each other.

[0069] For example, the elastic element 250 is disposed on the side of the main clamping arm 210 away from the chuck 240, so that the elastic element 250 and the chuck 240 are respectively located on both sides of the rotation axis of the main clamping arm 210, and the elastic element 250 provides elastic force for the reset of the main clamping arm 210.

[0070] After the cam 331 drives the active rod 310 to swing, causing the main clamping arm 210 and the slave clamping arm 220 to clamp, the main clamping arm 210 and the slave clamping arm 220 can be reset by the elastic force of the elastic element 250, so that the cam 331 and the follower bearing 333 on the connecting rod 332 always remain in close contact.

[0071] For example, the elastic element 250 can be a spring.

[0072] In one possible implementation, a guide rod 260 is provided on the main clamping arm 210, and an elastic element 250 is sleeved on the guide rod 260.

[0073] For example, a spring is sleeved on the guide rod 260 and is in a compressed state to provide a restoring force.

[0074] This application provides a bottle washing machine, including a bottle washing machine body and a clamping structure disposed on the bottle washing machine body.

[0075] The clamping structure in this embodiment is the same as the clamping structure provided in any of the above embodiments, and can bring the same or similar technical effects. It will not be described in detail here, but can be referred to the description of the above embodiments.

[0076] The bottle washing machine provided in this application embodiment rotatably mounts the main clamping arm 210 and the slave clamping arm 220 on the mounting base 100. The main clamping arm 210 and the slave clamping arm 220 are connected by a linkage 230, so that when the main clamping arm 210 rotates, it synchronously drives the slave clamping arm 220 to rotate in the opposite direction. The main clamping arm 210 and the slave clamping arm 220 cooperate to clamp the part to be clamped. The drive assembly 300 drives the main clamping arm 210 to rotate, thus achieving the clamping of the part to be clamped. The linkage 230 achieves synchronous reverse rotation of the main clamping arm 210 and the slave clamping arm 220, effectively reducing the pushing caused by the gripper's movement when clamping the part to be clamped, thereby improving the clamping accuracy and stability. It not only accurately clamps the part to be clamped but also maintains high reliability during high-speed operation of the bottle washing machine, effectively avoiding bottle dropping or positional deviation problems caused by unstable clamping, thus improving bottle washing efficiency and product quality.
