Technical Field
[0001] This application relates to the technical field of paint breaking, and in particular to a paint breaking device. Background Technology
[0002] Traditional barrel ear welding processes typically involve manual paint removal, which is inefficient and prone to causing uneven paint damage. Manually removing paint using sandpaper or other tools is inefficient and can result in uneven paint damage, affecting welding quality or creating large, unsightly areas of paint damage. Furthermore, manual paint removal is labor-intensive, easily causing worker fatigue and impacting both efficiency and quality. Summary of the Invention
[0003] In view of the shortcomings of the existing technology, the purpose of this application is to provide a paint breaking device that can achieve precise and convenient paint breaking location.
[0004] The above-mentioned objective of this application is achieved through the following technical solution:
[0005] A paint-breaking device is provided for performing paint-breaking operations on a workpiece to be welded. The workpiece to be welded includes a first component and a second component. The paint-breaking device includes a lifting mechanism that drives the first component to move along a first direction. The lifting mechanism includes a crank-connecting rod assembly that includes a clamping position and a welding position during operation. Between the clamping position and the welding position, there is also a paint-breaking position where the lifting mechanism drives the first component to move along the first direction.
[0006] The paint-breaking device further includes a clamping mechanism that clamps the second component and moves closer to or further away from the first component along a second direction perpendicular to the first direction.
[0007] This application further specifies that the crank-connecting rod assembly includes a crank structure and a connecting rod structure, one end of the crank structure is fixedly disposed, the other end of the crank structure is connected to one end of the connecting rod structure, and the other end of the connecting rod structure drives the first component to move along the first direction.
[0008] This application is further configured such that a tray is connected to the other end of the linkage structure, and the first component is placed on the tray.
[0009] This application is further configured such that the clamping mechanism has a receiving space, and a portion of the second component can be disposed within the receiving space.
[0010] The present application is further configured such that the clamping mechanism has a groove to form the receiving space, and the receiving space is provided with a magnetic material for attracting the second component.
[0011] This application further provides that the clamping mechanism is also provided with a welding head for welding the first component and the second component.
[0012] The application further specifies that the second component includes a tip for breaking paint, the tip protruding from the receiving space and disposed toward the first component.
[0013] The present application is further configured such that the number of the tip portions is multiple and they are distributed on one end of the second component opposite to the accommodating space.
[0014] This application further specifies that the number of clamping mechanisms is two, and the two clamping mechanisms are arranged opposite to each other on both sides of the lifting mechanism.
[0015] This application is further configured to include an inner top head for defining the position of the first component, the inner top head being disposed above the lifting mechanism.
[0016] In summary, the beneficial technical effects of this application are as follows:
[0017] 1. This application uses a lifting mechanism to drive the first component to move along a first direction and sets a paint breaking position, which can achieve precise paint breaking of the workpiece to be welded and effectively improve paint breaking efficiency.
[0018] 2. This application uses a crank-connecting rod assembly, which can control the paint breaking trajectory, achieve uniform paint breaking on curved surfaces, and improve the quality of paint breaking.
[0019] 3. This application utilizes a lifting mechanism and a clamping mechanism to automate the paint breaking process, reduce manual operation, lower labor intensity, improve production efficiency, reduce human error, and improve the quality and consistency of paint breaking.
[0020] 4.

Detailed Implementation
[0028] The present application will be further described in detail below with reference to the accompanying drawings.
[0029] like Figure 1 As shown, a component A to be welded is shown. Component A includes a first component A1 and a second component A3. Specifically, the upper end of the first component A1 forms an upper opening A2.
[0030] Preferably, the part to be welded A is a barrel-shaped object to be welded, the first part A1 is the barrel body, the second part A3 is the barrel handle, and the upper end of the barrel body is open to form the barrel mouth, i.e., the upper opening A2.
[0031] like Figures 2-3 As shown, a paint-breaking device includes a lifting mechanism 1 and a pressing mechanism 2. The lifting mechanism 1 drives a first component A1 to move along a first direction. The lifting mechanism 1 includes a crank-connecting rod assembly, which includes a clamping position and a welding position during operation. Between the clamping position and the welding position, there is also a paint-breaking position where the lifting mechanism 1 drives the first component A1 to move along the first direction. The pressing mechanism 2 clamps a second component A3 and moves closer to or away from the first component A1 along a second direction perpendicular to the first direction.
[0032] It is worth noting that the first direction in this application is as follows: Figure 2 The vertical direction is the first direction; the second direction is as follows: Figure 2 The left and right directions, i.e., the horizontal direction.
[0033] The operation of the paint breaking device is as follows: the first component A1 is transported to the lifting mechanism 1, the lifting mechanism 1 lifts the first component A1 to the clamping position, and the clamping mechanism 2 clamps the second component A3 close to the first component A1, so that the first component A1 and the second component A3 are in close contact; the lifting mechanism 1 drives the first component A1 to continue to move along the first direction. At this time, since the first component A1 and the second component A3 are in close contact, moving the first component A1 causes friction between the first component A1 and the second component A3 to achieve the paint breaking operation. After the paint breaking operation is completed, the welding operation can be carried out immediately.
[0034] It should be noted that when the lifting mechanism 1 is in the paint breaking position, the action of performing the paint breaking operation can be lifting the first component A1; when the lifting mechanism 1 is in the paint breaking position, the action of performing the paint breaking operation can also be lowering the first component A1; when the lifting mechanism 1 is in the paint breaking position, the action of performing the paint breaking operation can also be a combination of lifting the first component A1 and lowering the first component A1.
[0035] The crank-connecting rod assembly of the lifting mechanism 1 of this application automatically completes clamping, paint breaking, and welding steps during operation without manual intervention, thus improving operational efficiency and reducing labor costs. Automated operation avoids errors caused by human factors and ensures the stability and consistency of the paint breaking process.
[0036] The crank-connecting rod assembly used in this application is actually oscillating. The paint is broken by using the second part A3, which needs to be welded in the subsequent process. Even though the second part A3 and the first part A1 form an arc-shaped relative oscillation, it is different from the straight-line paint breaking or rotational paint breaking method.
[0037] Specifically, straight-line paint breaking means that the second component A3 moves in a straight line relative to the first component A1 to break the paint. This generates a lot of noise, and for barrel-shaped structures, the thickness of the broken paint is not easy to control. Furthermore, the first component A1 and the second component A3 are prone to damage. In addition, the broken paint area of straight-line paint breaking is large, which damages the integrity of the product's appearance.
[0038] Rotary paint breaking involves rotating around the axis of the second component A3 to break the paint. This method is prone to generating significant noise, and for barrel-shaped structures, it can result in the paint not being broken on both sides. Furthermore, the rotary paint breaking method generates significant friction, which can damage and deform the second component A3.
[0039] This application uses a crank-connecting rod assembly for oscillating paint breaking. Its slight curvature better accommodates the barrel-shaped first component A1. By adjusting the curvature and length of the oscillating paint breaking according to the dimensions of the first component A1 and the second component A3, relatively uniform paint breaking can be achieved. The wear on the first component A1 and the second component A3 is relatively small. Figure 5 As shown, the position of the first component A1 changes during the paint breaking process. During the paint breaking process, there is a gap J between the two extreme positions of the first component A1 in the first direction. The gap J is the distance that the first component A1 moves in the first direction during the paint breaking process.
[0040] In another preferred embodiment, the lifting mechanism 1 further includes a slider and a motor. The slider is connected to the connecting rod and moves linearly along a slide rail. The motor drives the crank to rotate, which in turn drives the connecting rod and the slider to move up and down. The cooperation between the slider and the slide rail converts the oscillating motion into a linear motion, which is used to break the paint on the workpiece A to be welded, which can adapt to the linear paint breaking method.
[0041] Furthermore, the crank-connecting rod assembly includes a crank structure 11 and a connecting rod structure 12. One end of the crank structure 11 is fixedly disposed, and the other end of the crank structure 11 is connected to one end of the connecting rod structure 12. The other end of the connecting rod structure 12 drives the first component A1 to move along a first direction.
[0042] Furthermore, a tray 13 is connected to the other end of the linkage structure 12, and the first component A1 is placed on the tray 13. The first component A1 is transported to the tray 13 by a conveyor belt or other industrially applicable transmission method, and the tray 13 moves the first component A1 in a first direction.
[0043] like Figure 4 As shown, the clamping mechanism 2 has a receiving space 21, and a part of the second component A3 can be disposed in the receiving space 21; the clamping mechanism 2 has a groove to form the receiving space 21, and the receiving space 21 is provided with a magnetic object 22 for attracting the second component A3. Specifically, the second component A3 is sent into the receiving space 21 through a conveying track.
[0044] The second component A3 requires no manual placement; it automatically enters the receiving space 21 via a conveyor track, simplifying the operation process, reducing manual intervention, and improving work efficiency. A magnetic material 22 attracts the second component A3, ensuring its precise positioning within the receiving space 21 and guaranteeing accurate relative positioning between the first component A1 and the second component A3, thereby enhancing the paint-breaking effect. Using a magnetic material 22 to attract the second component A3 avoids problems such as loosening and slippage that are common with traditional mechanical clamping methods, improving the reliability of the device and reducing the failure rate.
[0045] The clamping mechanism 2 is also equipped with a welding head for welding the first component A1 and the second component A3. The welding head is used to perform the welding process directly after the paint is broken.
[0046] The paint breaking and welding processes are integrated into one device, eliminating the need to separate the first component A1 and the second component A3. This simplifies the operation process and improves production efficiency.
[0047] The welding head and clamping mechanism 2 are integrated into one design. After the paint is removed, the first component A1 and the second component A3 are already precisely positioned, allowing for direct welding. This ensures accurate welding position and improves welding quality. Simultaneously, the integrated process reduces manual operation steps, minimizes errors caused by manual handling, improves product consistency, and lowers production costs.
[0048] Integrating paint breaking and welding functions into one device saves production space, improves equipment flexibility, and facilitates production operations in limited spaces.
[0049] like Figure 6 As shown, the structure of the second component A3 is illustrated. The second component A3 includes a tip A31 for breaking paint. The tip A31 protrudes from the receiving space 21 and is disposed toward the first component A1. There are multiple tips A31 and they are distributed on one end of the second component A3 opposite to the receiving space 21.
[0050] Multiple pointed tips A31 act simultaneously on the first component A1, which can effectively increase the paint breaking area, shorten the paint breaking time, and improve the paint breaking efficiency. Multiple pointed tips A31 are distributed at one end of the second component A3, forming a paint breaking surface, which can effectively enhance the paint breaking effect and improve the paint breaking depth and uniformity.
[0051] The number and distribution of the tips A31 can be adjusted according to actual needs to accommodate first components A1 of different sizes and shapes, improving the flexibility of paint breaking. Multiple tips A31 disperse the paint breaking pressure, reducing localized pressure on the first component A1 and preventing excessive deformation or damage during the paint breaking process. The even distribution of multiple tips A31 effectively enhances the stability of the paint breaking process, reducing the risk of vibration or deviation during the process.
[0052] There are two clamping mechanisms 2, which are arranged opposite to each other on both sides of the lifting mechanism 1. Furthermore, the two clamping mechanisms 2 move synchronously, that is, they move closer to or further away from the first component A1 simultaneously. Preferably, the intelligent high-speed welding earphone for a round can is selected from the intelligent high-speed welding earphone for a round can in Chinese invention patent application document CN109108555A.
[0053] See Figure 3 As shown, the paint breaking device also includes an inner top head 3 for defining the position of the first component A1. The inner top head 3 is located above the lifting mechanism 1 and extends into the upper opening A2 of the component A to be welded, thereby providing support for paint breaking and subsequent welding processes.
[0054] The inner top head 3 in this application limits the position of the first component A1 during the paint breaking operation, ensuring that the first component A1 remains fixed during the paint breaking and welding process, avoiding welding defects caused by positional deviations and improving welding quality.
[0055] The inner top head 3 provides support for the first component A1, keeping it stable during the paint breaking process. This avoids uneven paint breaking or damage caused by the shaking of the first component A1, improves paint breaking efficiency and effect, and also avoids the denting and deformation caused by the pressure applied during paint breaking and welding on both sides. This protects the integrity of the first component A1 and reduces production losses.
[0056] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
